SURFACE WATER SUPPLY OF THE NORTH PACIFIC

COAST, 1909.

By J. C. STEVENS, E. C. LA RUE, and F. F. HENSHAW.

INTRODUCTION.

AUTHORITY FOR INVESTIGATIONS.

This volume contains results of flow measurements made on certain streams in the United States. The work was performed by 

the water-resources branch of the United States Geological Survey, 

either independently or in cooperation with organizations mentioned 

herein. These investigations are authorized by the organic law of 

the Geological Survey (Stat. L., vol. 20, p. 394), which provides, 

among other things, as follows:

Provided that this officer [the Director] shall have the direction of the Geological 

Survey and the classification of public lands and examination of the geological structure, mineral resources, and products of the national domain.

Inasmuch as water is the most abundant and most valuable mineral 

in nature, the investigation of water resources is included under the 

above provision for investigating mineral resources. The work has 

been supported since the fiscal year ending June 30, 1895, by appropriations in successive sundry civil bills passed by Congress under the 

following item:

For gaging the streams and determining the water supply of the United States, and 

for the investigation of underground currents and artesian wells, and for the preparation of reports upon the best methods of utilizing the water resources.

The various appropriations that have been made for this purpose are 

as follows:

Annual appropriations for the fiscal year ending June 30 

1895............................................................... $12,500

1896............................................................... 20,000

1897 to 1900, inclusive............................................. 50,000

12 SURFACE WATEE SUPPLY, 1909, PART XII. 

SCOPE OF INVESTIGATIONS.

These investigations are not complete, nor do they include all the 

river systems, or parts thereof, that might purposefully be studied. 

The' scope of the work is limited by the appropriations available. 

The field covered is the widest and the character of the work is 

believed to be the best possible under the controlling conditions. 

The work would undoubtedly have greater scientific importance and 

ultimately be of more practical value if the money now expended 

for wide areas were concentrated on a few small drainage basins; 

but such a course is impossible because general appropriations made 

by Congress are applicable to all parts of the country. Each part 

demands its proportionate share of the benefits.

It is essential that records of stream flow shall be kept during a 

period of years long enough to determine within reasonable limits 

the entire range of flow from the absolute maximum to the absolute 

minimum. The length of such a period manifestly differs for different 

streams. Experience has shown that the records for some streams 

should cover from 5 to 10 years, and for other streams 20 years or 

even more, the limit being determined by the relative importance 

of the stream and the interdependence of the results and other 

long-time records on adjacent streams.

In the performance of this work an effort is made to reach the 

highest degree of precision possible with a rational expenditure of 

time and a judicious expenditure of a small amount of money. In 

all engineering work there is a point beyond which refinement is 

needless and wasteful, and this statement applies with especial force 

to stream-flow measurements. It is confidently believed that the 

stream-flow data presented in the publications of the Survey are in 

general sufficiently accurate for all practical purposes. Many of the 

records are, however, of insufficient length, owing to the unforeseen 

reduction of appropriations and consequent abandonment of stations. All persons are cautioned to exercise the greatest care in using 

such incomplete records.

Records have been obtained at more than 1,550 different points in 

the United States, and in addition the surface water supply of small 

areas in Seward Peninsula and the Yukon-Tanana region, Alaska, 

has been investigated. During 1909 regular gaging stations were 

maintained by the Survey and cooperating organizations at about 850 

points in the United States, and many miscellaneous measurements 

were made at other points. Data were also obtained in regard to 

precipitation, evaporation, storage reservoirs, river profiles, and 

water power in, many sections of the country, and will be made 

available in the regular surface water-supply papers and in special 

papers from time to time.

PURPOSES OF THE WORK.

The results contained in this volume are requisite to meet the 

immediate demands of many public interests, including navigation, 

irrigation, domestic water supply, water power, swamp and overflow 

land drainage, and flood prevention.

Navigation. The Federal Government has expended more than 

$250,000,000 for the improvement of inland navigation, and prospective expenditures will approximate several times this amount. It is 

obvious that the determination of stream flow is necessary to the 

intelligent solution of the many problems involved.

Irrigation. The United States is now expending $51,000,000 on 

Federal irrigation' systems, and this amount is far exceeded by the 

private expenditures of this nature in the arid West. The integrity 

of any irrigation system depends absolutely on the amount of water 

available. Therefore investigations of stream flow in that portion 

of the country are not only of first importance in the redemption of 

the lands, but constitute an insurance of Federal and private investments.

Domestic water supply. The highest use of water is for domestic 

supply, and although this branch of the subject is of less direct 

Federal interest than the branches already named, it nevertheless 

has so broad a significance with respect to the general welfare that 

the Federal Government is ultimately and intimately concerned.

Water power. The development of the water power of the country 

is an economic necessity. Our stock of coal is being rapidly depleted 

and the cost of steam power is increasing accordingly. Industrial 

growth and, as a consequence, the progress of the United States as a 

nation will cease if cheap power is not available. Water power 

affords the only avenue now open. When the electric transmission 

of power was accomplished the relation of our water powers to national 

economy changed entirely. Before the day of electric transmission 

water power was important only at the locality at which it was generated, but it has now become a public utility in which the individual 

citizen is vitally interested. Inasmuch as the amount of water power 

that may be made available depends on the flow of rivers, the investigation of flow becomes a prerequisite in the judicious management 

of this source of energy.

Drainage of swamp and overflowed lands. More than 70,000,000 

acres of the richest land in this country are now practically worthless 

or of precarious value by reason of overflow and swamp conditions. 

When this land is drained it becomes exceedingly productive and 

its value increases many fold. Such reclamation would add to the 

national assets at least $700,000,000. The study of run-off is the 

first consideration in connection with drainage projects. If by the
14 SURFACE WATEE SUPPLY, 1909, PART XII.

drainage of a large area into any particular channel that channel 

becomes so gorged with water which it had not hitherto been called 

on to convey that overflow conditions are created in places where previously the land was not subject to inundation, then drainage results 

merely in an exchange of land values. This is not the purpose of 

drainage improvement.

Flood prevention. The damage from floods in the United States 

probably exceeds on the average $100,000,000 annually, and in the 

year 1908, according to estimates based on reliable data, the aggregate damage approximated $250,000,000. Such an annual tax on 

the property of great regions should be reduced in the orderly progress of government. It goes without saying that any consideration 

of flood prevention must be based on a thorough knowledge of stream 

flow, both in the contributing areas which furnish the water and along 

the great lowland rivers.

PUBLICATIONS.

The data on stream flow collected by the United States Geological 

Survey since its inception have appeared in the annual reports, 

bulletins, and water-supply papers. Owing to natural processes of 

evolution and to changes in governmental requirements, the character 

of the work and the territory covered by these different publications 

have varied greatly. For the purpose of uniformity in the presentation of reports a general plan has been agreed upon by the United 

States Reclamation Service, the United States Forest Service, the 

United States Weather Bureau, and the United States Geological 

Survey, according to which the area of the United Spates has been

The order of treatment of stations in any basin in these papers is 

downstream. The main stem of any river is determined on the 

basis of drainage area, local changes in name and lake surface being 

disregarded. After all stations from the source to the mouth of the 

main stem of the river have been given, the tributaries are taken up 

in* regular order from source to mouth. The tributaries are treated 

the same as the main stream, all stations in each tributary basin 

being given before taking up the next one below.

The exceptions to this rule occur in the records for Mississippi 

River, which are given in four parts, as indicated above, and in the 

records for large lakes, where it is often clearer to take up the streams 

in regular order around the rim of the lake than to cross back and 

forth over the lake surface.

DEFINITION OF TERMS.

The volume of water flowing in a stream the "run-off" or "discharge" is expressed in various terms, each of which has become 

associated with a certain class of work. These terms may be divided 

into two groups: (1) Those which represent a rate of flow, as secondfeet, gallons per minute, miner's inches, and run-off in second-feet 

per square mile, and (2) those which represent the actual quantity 

of water, as run-off in depth in inches and acre-feet. They may be 

defined as f ollows:

" Second-foot "'is an abbreviation for cubic foot per second and is 

the rate of discharge of water flowing in a stream 1 foot wide, 1 foot 

deep, at a rate of 1 foot per second. It is generally used as a fundamental unit from which otners are computed by the use of the factors 

given in the following table of equivalents.

"Gallons per minute" is generally used in connection with pumping 

and city water supply.

The " miner's inch" is the rate of discharge of water that passes 

through an orifice 1 inch square under a head which varies locally.

It is commonly used by miners and irrigators throughout the West 

and is defined by statute in each State in which it is used.

"Second-feet per square mile" is the average number of cubic feet 

of water flowing per second from each square mile of area drained, 

on the assumption that the run-off is distributed uniformly both as 

regards time and area.

"Run-off, depth in inches on drainage area," is the depth to which 

the drainage area would be covered if all the water flowing from it in 

a given period were conserved and uniformly distributed on the surface. It is used for comparing run-off with rainfall, which is usually 

expressed in depth in inches.

84547° WSP 272 11 2
18 SURFACE WATER SUPPLY, 1909, PART XII.

"Acre-foot" is equivalent to 43,560 cubic feet, and is the quantity 

required to cover an acre to tlie depth of 1 foot. It is commonly 

used in connection with storage for irrigation work.

EXPLANATION OF TABLES.

For each drainage basin there is given a brief description of general conditions covering such features as area, source, tributaries, 

topography, geology, conditions of forestation, rainfall, ice conditions, 

irrigation, storage, power possibilities, and other special features of 

importance or interest.

For each regular current-meter gaging station are given in general, 

and so far as available, the following data: Description of station, 

list of discharge measurements, table of daily gage heights, table 

of daily discharges, table of monthly and yearly discharges and 

run-off. For stations located at weirs or dams the gage-height table 

is omitted.

In addition to statements regarding the location and installation 

of current-meter stations the descriptions give information in regard 

to any conditions which may affect the constancy of the relation of 

gage height to discharge, covering such points as ice, logging, shifting conditions of flow, and backwater; also information regarding 

diversions which decrease the total flow at the measuring section. 

Statements are also made regarding the accuracy and reliabilty of 

the data.

The discharge-measurement table gives the results of the discharge 

measurements made during the year, including the date, name of 

hydrographer, width and area of cross section, gage height, and 

discharge in second-feet.

The table of daily gage heights gives the daily fluctuations of the 

surface of the river as found from the mean of the gage readings 

taken each day. At most stations the gage is read in the morning 

and in the evening. The gage height given in the table represents 

the elevation of the surface of the water above the zero of the gage. 

All gage heights during ice conditions, backwater from obstructions, 

etc., are published as recorded, with suitable footnotes. The rating 

is not applicable for such periods unless the proper corrections to 

the gage heights are known and applied. Attention is called to the 

fact that the zero of the gage is placed at an arbitrary datum and has 

no relation to zero flow or the bottom of the river. In general, the 

zero is located somewhat below the lowest known flow, so that 

negative readings shall not occur.
20 SURFACE WATEE SUPPLY, 1909, PART XII.

The discharge measurements and gage heights are the base data 

from which rating tables, daily-discharge tables, and monthly-discharge tables are computed.

The rating table gives, either directly or by interpolation, the 

discharge in second-feet corresponding to every stage of the river 

recorded during the period for which it is applicable. It is not published in this report but can be determined from the daily gage 

heights and daily discharges for the purpose of verifying the published results as follows:

First plot the discharge measurements for the current and earlier 

years on cross-section paper with gage heights in feet as ordinates 

and discharge in second-feet as abscissas. Then tabulate a number 

of gage heights taken from the daily gage-height table for the complete range of stage given and the corresponding discharges for the 

days selected from the daily-discharge table and plot the values on 

the cross-section paper. The last points plotted will define the 

rating curve used and will lie among the plotted discharge measurements. After drawing the rating curve, a table can be developed 

by scaling off the discharge in second-feet for each tenth foot of 

gage height. These values should be so adjusted that the first differences shall always be increasing or constant, except for known 

back-water conditions.

The table of daily discharges gives the discharges in second-feet 

as determined from the rating tables corresponding to the observed 

gage heights.

In the table of monthly discharge the column headed "Maximum" 

gives the mean flow, as determined from the rating table, for the day 

when the mean gage height was highest. As the gage height is the 

mean for the day, it does not indicate correctly the stage when the 

water surface was at crest height and the corresponding discharge 

consequently larger than given in the maximum column. Likewise, 

in the column of "Minimum" the quantity given is the mean flow for 

the day when the mean gage height was lowest. The column headed 

"Mean" is the average flow in cubic feet for each second during the 

month. On this the computations for the remaining columns, 

which are defined on page 17, are based.

FIELD METHODS OF MEASURING STREAM FLOW.

There are three distinct methods of determining the flow of openchannel streams: (1) By measurements of slope and cross section 

and the use of Chezy's and Kutter's formula; (2) by means of a 

weir or dam; (3) by measurements of the velocity of the current and 

of the area of the cross section. The method chosen depends on the 

local physical conditions, the degree of accuracy desired, the funds 

available, and the length of time that the record is to be continued.
NORTH PACIFIC COAST. 21

Slope method. Much information has been collected relative to the 

coefficients to be used in the Chezy formula, v=c~\/Rs. This has 

been utilized by Kutter, both in developing his formula for c and in 

determining the values of the coefficient n which appears therein. 

The results obtained by the slope method are in general only roughly 

approximate, owing to the difficulty hi obtaining accurate data and 

the uncertainty of the value for n to be used in Kutter's formula. 

The most common use of this method is in estimating the flood discharge of a stream when the only data available are the cross section, 

the slope as shown by marks along the bank, and a knowledge of the 

general conditions. It is seldom used by the United States Geological Survey. For full information regarding this method the 

reader is referred to the various textbooks on hydraulics.

Weir method. Relatively few stations are maintained at weirs or 

dams by the United States Geological Survey. Standard types of 

sharp-crested and broad-crested weirs within the limits for which 

accurate coefficients have been experimentally obtained give very 

accurate records of discharge if properly maintained. At practically 

all broad-crested weirs, however, there is a diversion of water either 

through or around the dam, usually for the purpose of development 

of water power. The flow is often complicated, and the records are 

subject to errors from such sources as leakage through the dam, 

backwater at high stages, uncertainty regarding coefficient, irregularity of crest, obstructions from logs or ice, use of flashboards, old 

turbines with imperfect ratings, and many others depending on the 

type of development and the uses of the diverted water.

In general, records of discharge at dam are usually accurate enough 

for practical use if no others are available. It has been the general 

experience of the United States Geological Survey, however, that 

records at current-meter gaging stations under unobstructed channel 

conditions are more accurate than those collected at dams, and where 

the conditions are reasonably favorable are practically as good as 

those obtained at sharp-crested weirs.1

Velocity method. Streams in general present throughout their 

courses, to a greater or less extent, all conditions of permanent, semipermanent, and varying conditions of flow. In accordance with the 

location of the measuring section with respect to these physical conditions, current-meter gaging stations may in general be divided 

into four classes (1) those with permanent conditions of flow; 

(2) those with beds which change only during extreme high water;

1 The determination of discharge over the different types of weirs and dams is treated fully in "Weir 

experiments, coefficients, and formulas" (Water-Supply Paper 200) and in the various textbooks on 

hydraulics. "Turbine water-wheel tests and power tables" (Water-Supply Paper 180) treats of the discharge through turbines when used as meters. The edition of the latter paper is nearly exhausted. It 

can, however, be consulted at most of the larger libraries of the country, or can be obtained from the Superintendent of Documents, Washington, D. C., at a cost of 20 cents.
22 SURFACE WATEK SUPPLY, 1909, PART XII.

(3) those with beds which change frequently but which do not cause 

a variation of more than about 5 per cent of the discharge curves 

from year to year; and (4) those with constantly shifting beds. 

In determining the daily flow different office methods are necessary 

for each class. The field data on which the determinations are 

based and the methods of collecting them are, however, in general 

the same.

Great care is taken in the selection and equipment of gaging 

stations for determining discharge by velocity measurements, in 

order that the data may have the required degree of accuracy. 

They are located, as far as possible, at such points that the relation 

between gage height and discharge will always remain constant 

for any given stage. The experience of engineers of the Geological 

Survey has been that permanency of conditions of flow is the prime 

requisite of any current-meter gaging station when maintained for 

several years unless funds are available to cover all changes in conditions of flow. A straight, smooth section without cross currents, 

backwater, boils, etc., at any stage is highly desirable, but on most 

streams is not attainable except at the cost of a cable equipment/ 

Rough, permanent sections, if measurements are properly made by 

experienced engineers, taking measuring points at a distance apart 

of 2 to 5 per cent or less of the total width, will within reasonable 

limits yield better results for a given outlay of money than semipermanent or shifting sections with smooth, uniform current. So far 

as possible stations are located where the banks are high and not 

subject to overflow at high stages and out of the influence of tributary 

streams, dams, or other artificial obstructions which might affect the 

relation between gage height and discharge.

A gaging station consists essentially of a gage for determining 

the daily fluctuations of stage of the river and some structure or 

apparatus from which discharge measurements are made usually a 

bridge or cable.

The two factors required to determine the discharge of a stream 

past a section perpendicular to the mean direction of the current 

are the area of the cross section and the mean velocity of flow normal 

to that section.

In making a measurement with a current meter a number of 

points, called measuring points, are measured off above and in the 

plane of the measuring section at which observations of depth and 

velocity are taken. (See PI. I, A) These points are spaced equally 

for those parts of the section where the flow is uniform and smooth 

and are spaced unequally for other parts, according to the discretion 

and judgment of the engineer. In general the points should not be 

spaced farther apart than 5 per cent of the distance between piers, 

nor farther apart than the approximate mean depth of the section 

at the time of. measurement.

B. FOR WADING MEASUREMENT. 

TYPICAL GAGING STATIONS.

NORTH PACIFIC COAST. 23

The measuring points divide the total cross section into elementary 

strips at each end of which observations of depth and velocity are 

made. The discharge of any elementary strip is the product of the 

average of the depths at the two ends times the width of the strip 

times the average of the mean velocities at the two ends of the strip. 

The sum of the discharges of the elementary strips is the total discharge of the stream.1

Depths for the determination of the area are usually obtained by 

sounding with the current meter and cable. In rough sections or 

swift current an ordinary weight and cable are used, particular care 

being taken that all observations shall be in the plane of the cross 

section.

Two methods of determining the velocity of flow of a stream are 

in general use the float method and the current-meter method.

The float method, with its various modifications of surface, subsurface, and tube or rod floats, is now considered obsolete in the ordinary practice of the United States Geological Survey. The use of 

this method is limited to special conditions where it is impracticable 

to use the current meter, such as in places where large quantities of 

ice or debris which may damage the meter are flowing with the current, and for miscellaneous measurements or other work where a 

high degree of accuracy is not necessary. Tube floats are very satisfactory for use in canals with regular bottoms and even flow of current. Measurements by the float method are made as follows: 

The velocity of flow of the stream is obtained by observing the time 

which it takes floats set free at different points across the stream 

to pass between two range lines about 200 feet apart. The area 

used is the mean value obtained from several cross sections measured 

between the two range lines. The chief disadvantages of this method 

are difficulty in obtaining the correct value of mean area for the 

course used and uncertainty regarding the proper coefficient to 

apply to the observed velocity.2

The Price current meter is now used almost to the exclusion of 

other types of meters by the United States Geological Survey in the 

determination of the velocity of flow of water in open channels, a 

use for which it is adapted under practically all conditions.3 Plate 

II shows in the center the new type of penta-recording current meter 

equipped for measurements at bridge and cable stations; on the left 

the same type of meter is shown equipped for wading measurements

however, be consulted at most of the larger libraries of the country, or can be obtained from the Superintendent of Documents, Washington, D. C., at a cost of 15 cents.

to record by the acoustic method; on the right tJ' e meter is shown 

equipped to record electrically. (See PI. I, B.) Briefly, the meter 

consists of six cups attached to a vertical shaft which revolves on a 

conical hardened-steel point when immersed in moving water. The 

revolutions are indicated electrically. The rating, or the relation 

between the velocity of the moving water and the revolutions of the 

wheel, is determined for each meter by drawing it through still water 

for a given distance at different speeds and noting the number of revolutions for each run. From the data thus obtained a rating table is 

prepared which gives the velocity per second of moving water for any 

number of revolutions in a given time interval. The ratio of revolutions per second to velocity of flow in feet per second is very nearly a 

constant for all speeds and is approximately 0.45.

Three classes of methods of measuring velocity with current meters 

are in general use multiple-point, single-point, and integration.

The two principal multiple-point methods in general use are the 

vertical velocity curve and 0.2 and 0.8 depth.

In the vertical velocity curve method a series of velocity determinations are made in each vertical at regular intervals, usually about 

10 to 20 per cent of the depth apart. By plotting these velocities as 

abscissas and their depths as ordinates and drawing a smooth curve 

among the resulting points, the vertical velocity curve is developed. 

This curve shows graphically the magnitude and changes in velocity 

from the surface to the bottom of the stream. The mean velocity 

in the vertical is then obtained by dividing the area bounded by 

this velocity curve and its axis by the depth. This method of obtaining the mean velocity in the vertical is probably the best known, 

but. on account of the length of time required to make a complete 

measurement its use is largely limited to the determination of coefficients for purposes of comparison and to measurements under ice.

In the second multiple-point method the meter is held successively 

at 0.2 and 0.8 depth, and the mean of the velocities at these two points 

is taken as the mean velocity for that vertical. (See PI. I, A.) On 

the assumption that the vertical velocity curve is a common parabola 

with horizontal axis, the mean of the velocities at 0.22 and 0.79 depth 

will give (closely) the mean velocity in the vertical. Actual observations under a wide range of conditions show that this multiple-point 

method gives the mean velocity very closely for open-water conditions and that in a completed measurement it seldom varies as much 

as 1 per cent from the value given by the vertical velocity curve 

method. Moreover, the indications are that it holds nearly as well 

for ice-covered rivers. It is very extensively used in the regular 

practice of the United States Geological Survey.

The single-point method consists in holding the meter either at 

the depth of the thread of mean velocity or at an arbitrary depth

for which the coefficient for reducing to mean velocity has been 

determined or must be assumed.

Extensive experiments by means of vertical velocity curves show 

that the thread of mean velocity generally occurs between 0.5 and 

0.7 total depth. In general practice the thread of mean velocity is 

considered to be at 0.6 depth, and at this point the meter is held in 

most of the measurements made by the single-point method. A 

large number of vertical velocity curve measurements, taken on 

many streams and under varying conditions, show that the average 

coefficient for reducing the velocity obtained at 0.6 depth to mean 

velocity is practically unity. The variation of the coefficient from 

unity in individual cases is, however, greater than in the 0.2 and 

0.8 method and the general results are not as satisfactory.

In the other principal single-point method the meter is held near 

the surface, usually 1 foot below, or low enough to be out of the effect 

of the wind or other disturbing influences. This is known as the subsurface method. The coefficient for reducing the velocity taken at 

the subsurface to the mean has been found to be in general from 

about 0.85 to 0.95, depending on the stage, velocity, and channel 

conditions. The higher the stage the larger the coefficient. This 

method is especially adapted for flood measurements, or when the 

velocity is so great that the meter can not be kept in the correct 

position for the other methods.

The vertical integration method consists in moving the meter at a 

slow, uniform speed from the surface to the bottom and back again 

to the surface and noting the number of revolutions and the time 

taken in the operation. This method has the advantage that the 

velocity at each point of the vertical is measured twice. It is useful 

as a check on the point methods. In using the Price meter great 

care should be taken that the vertical movement of the meter is not 

rapid enough to vitiate the accuracy of the resulting velocity.

The determination of the flow of an ice-covered stream is difficult, 

owing to diversity and instability of conditions during the winter 

period and also to lack of definite information in regard to the laws of 

flow of water under ice. The method now employed is to make frequent discharge measurements during the frozen periods by the 0.2 

and 0.8 and the vertical velocity curve methods, and to keep an 

accurate record of the conditions, such as the gage height to the surface of the water as it rises in a hole cut in the ice, and the thickness 

and character of the ice. From these data an approximate estimate 

of the daily flow can be made by constructing a rating curve (really 

a series of curves) similar to that used for open channels, but considering, in addition to gage heights and discharge, the varying thickness of ice.1

26 SURFACE WATER SUPPLY, 1909, PART XII.

OFFICE METHODS OF COMPUTING AND STUDYING DISCHARGE AND

RUN-OFF.

At the end of each year the field or base data for current-meter 

gaging stations, consisting of daily gage heights, discharge measurements, and full notes, are assembled. The measurements are plotted 

on cross-section paper and rating curves are drawn wherever feasible. 

The rating tables prepared from these curves are then applied to 

the tables of daily gage heights to obtain the daily discharges, and 

from these applications the tables of monthly discharge and run-off 

are computed.

Rating curves are drawn and studied with special reference to 

the class of channel conditions which they represent. (See p. 21.) 

The discharge measurements for all classes of stations when plotted 

with gage heights in feet as ordinates and discharges in second-feet 

as abscissas define rating curves which are more or less generally 

parabolic in form. In many cases curves of area in square feet 

and mean velocity in feet per second are also constructed to the 

same scale of ordinates as the discharge curve. These are used 

mainly to extend the discharge curves beyond the limits of the 

plotted discharge measurements, and for checking purposes to avoid 

errors in the form of the discharge curve and to determine and eliminate erroneous measurements. Plate III shows a typical rating 

curve.

For every rating table prepared the following assumptions are 

made for the period to which the table applies: (a) That the discharge is a function of and increases gradually with the stage; (&) 

that the discharge is the same whenever the stream is at a given 

stage, and hence such changes in conditions of flow as may have 

occurred during the period of application are either compensating or 

negligible, except that the rating as stated in the footnote of each 

table is not applicable for known conditions of ice, log jams, or other 

similar obstructions; (c) that the increased and decreased discharge 

due to change of slope on rising and falling stages is either negligible 

or compensating.

As already stated, the gaging stations may be divided into several 

classes, as indicated in the following paragraphs:

The stations of class 1 represent the most favorable conditions for 

an accurate rating and are also the most economical to maintain. 

The bed of the stream is usually composed of rock and is not subject 

to the deposit of sediment and loose material. This class includes 

also many stations located in a pool below which is a permanent 

rocky riffle that controls the flow like a weir. Provided the control 

is sufficiently high and close to the gage to prevent cut and fill at the 

gaging point from materially affecting the slope of the water surface,

the gage height will for all practical purposes be a true index of the 

discharge. Discharge measurements made at such stations usually 

plot within 2 or 3 per cent of the mean-discharge curve, and the rating 

developed from that curve represents a very high degree of accuracy. 

Stations of this type are found in the north Atlantic coast drainage

Class 2 is confined mainly to stations on rough mountainous streams 

with steep slopes. The beds of such streams are, as a rule, comparatively permanent during low and medium stages, and when the flow 

is sufficiently well defined by an adequate number of discharge 

measurements before and after each flood the stations of this class 

give nearly as good results as those of class 1. As it is seldom possible to make measurements covering the time of change at flood 

stage, the assumption is often made that the curves before and after 

the flood converged to a common point at the highest gage height 

recorded during the flood. Hence, the only uncertain period occurs 

during the few days of highest gage heights covering the period of 

actual change in conditions of flow. Stations of this type are found 

in the upper Missouri River drainage basin.

Class 3 includes most of the current-meter gaging stations maintained by the United States Geological Survey. If sufficient measurements could be made at stations of this class results would be 

obtained nearly equaling those of class 1, but owing to the limited 

funds at the disposal of the Survey this is manifestly impossible, 

nor is it necessary for the uses to which discharge data are applied. 

The critical points are, as a rule, at relatively high or low stages. 

Percentage error, however, is greater at low stages. No absolute rule 

can be laid down for stations of this class. Each rating curve must 

be constructed mainly on the basis of the measurements of the current 

year, the engineer being guided largely by the past history of the 

station and the following general law: If all measurements ever made 

at a station of this class are plotted on cross-section paper, they will 

define a mean curve which may be called a standard curve. It has 

been found in practice that if after a change caused by high stage, a 

relatively constant condition of flow occurs at medium and low 

stages, all measurements made after the change will plot on a smooth 

curve which is practically parallel to the standard curve with respect 

to the ordinates or gage heights. This law of the parallelism of ratings is the fundamental basis of all ratings and estimates at stations 

with semipermanent and shifting channels. It is not absolutely correct, but with few exceptions answers all the practical requirements 

of estimates made at low and medium stages after a change at a 

high stage. This law appears to hold equally true whether the 

change occurs at the measuring section or at some controlling point 

below. The change is of course fundamentally due to change in
28 SURFACE WATER SUPPLY, 1909, PART XII.

the channel caused by cut or fill, or both, at or near the measuring 

section. For all except small streams the changes in section usually 

occur at the bottom. The following simple but typical examples 

illustrate this law:

(a) If 0.5 foot of planking were to be nailed on the bottom of a 

well-rated wooden flume of rectangular section, there would result, 

other conditions of flow being equal, new curves of discharge, area, 

and velocity, each plotting 0.5 foot above the original curves when 

referred to the original gage. In other words, this condition would 

be analogous to a uniform fill or cut in a river channel which either 

reduces or increases all three values of discharge, area, and velocity 

for any gage height. In practice, however, such ideal conditions 

rarely exist.

(&) In the case of a cut or fill at the measuring section there is a 

marked tendency toward decrease or increase, respectively, of the 

velocity. In other words, the velocity has a compensating effect, 

and if the compensation is exact at all stages the discharge at a given 

stage will be the same under both the new and the old. conditions.

(c) In the case of uniform change along the crest of a weir or rocky 

control point, the area curve will remain the same as before the 

change, and it can be shown that here again the change in velocity 

curve is such that it will produce a new discharge curve essentially 

parallel to the original discharge curve with respect to their ordinates.

Of course, in actual practice such simple changes of section do not 

occur. The changes are complicated and lack uniformity, a cut at 

one place being largely offset by a fill at another and vice versa. 

If these changes are very radical and involve large percentages of 

the total area as, for example, on small streams there may result 

a wide departure from the law of parallelism of ratings. In complicated changes of section the corresponding changes in velocity 

which tend to produce a new parallel discharge curve may interfere 

with each other materially, causing eddies, boils, backwater, and 

radical changes in slope. In such extreme conditions, however, the 

measuring section would more properly fall under class 4 and would 

require very frequent measurements of discharge. Special stress is 

laid on the fact that in the lack of other data to the contrary the 

utilization of this law will yield the most probable results.

Slight changes at low or medium stages of an oscillating character 

are usually averaged by a mean curve drawn among them parallel 

to the standard curve, and if the individual measurements do not 

vary more -than 5 per cent from the rating curve the results are 

considered good for stations of this class. Stations of this type are 

found in the south Atlantic coast and eastern Gulf of Mexico drainage 

basins.
NOKTH PACIFIC COAST. 29

Class 4 comprises stations that have soft, muddy, or sandy beds. 

Good results can be obtained from such sections only by frequent 

discharge measurements, the frequency varying from a measurement every two or three weeks to a measurement every day, according to the rate of diurnal change in conditions of flow. These measurements are plotted and a mean or standard curve drawn among 

them. It is assumed that there is a different rating curve for 

every day of the year and that this rating is parallel to the standard 

curve with respect to their ordinates. On the day of a measurement the rating curve for that day passes through that measurement. For days between successive measurements it is assumed 

that the rate of change is uniform, and hence the ratings for the 

intervening days are equally spaced between the ratings passing 

through the two measurements. This method must be modified or 

abandoned altogether under special conditions. Personal judgment and a knowledge of the conditions involved can alone dictate 

the course to pursue in such cases. Stations of this type are found 

in the Platte, Arkansas, Rio Grande, and lower Colorado drainage 

basins.

The computations have, as a rule, been carried io three significant 

figures. Computation machines, Crelle's tables, and the 20-inch 

slide rule have been generally used. All computations are carefully 

checked.

After the computations have been completed they are entered in 

tables and carefully studied and intercompared to eliminate or 

account for all gross errors so far as possible. Missing periods are 

filled in, so far as is feasible, by means of comparison with adjacent 

streams. The attempt is made to complete years or periods of discharge, thus eliminating fragmentary and disjointed records. Full 

notes accompanying such estimates follow the daily and monthly 

discharge tables.

For most of the northern stations estimates have been made on 

the monthly discharge during frozen periods. These are based on 

measurements under ice conditions whenever available, daily records 

of temperature and precipitation obtained from the United States 

Weather Bureau climate and crop reports, observers' notes of conditions, and a careful and thorough intercomparison of results with 

adjacent streams. Although every care possible is used in making 

these estimates they are often very rough, the data for some of 

them being so poor that the estimates are liable to as much as 25 

to 50 per cent error. It is believed, however, that estimates of this 

character are better than none at all, and serve the purpose of indicating in a relative way the proportionate amount of flow during 

the frozen period. These estimates are, as a rule, included in the 

annual discharge. The large error of the individual months has a
30 SURFACE WATER SUPPLY, 1909, PAET XII.

relatively small effect on the annual total, and it is for many purposes desirable to have the yearly discharge computed, even though 

some error is involved in doing so.

ACCURACY AND RELIABILITY OF FIELD DATA AND COMPARATIVE

RESULTS.

Practically all discharge measurements made under fair conditions are well within 5 per cent of the true discharge at the time of 

observation. Inasmuch as the errors of meter measurements are 

largely compensating, the mean rating curve, when well defined, is 

much more accurate than the individual measurements. Numerous 

tests and experiments have been made to test the accuracy of currentmeter work. These show that it compares very favorably with the 

results from standard weirs, and, owing to simplicity of methods, 

usually gives results that are much more reliable than those from 

stations at dams, where uncertainty regarding the coefficient and 

complicated conditions of flow prevails.

The work is, of course, dependent on the reliability of the observers. 

With relatively few exceptions the observers perform their work 

honestly. Care is, taken, however, to watch them closely and to 

inquire into any discrepancies. It is, of course, obvious that one 

gage reading a day does not always give the mean height for that 

day. As an almost invariable rule, however, errors from this source 

are compensating and virtually negligible in a period of one month, 

although a single day's reading may, when taken by itself, be considerably in error.

The effort is made to visit every station at least once each year 

for the purpose of making a measurement to determine the constancy of conditions of flow since the last measurement made during 

the preceding year, and also to check the elevation of the gage. On 

account of lack of funds or for other causes some stations were not 

visited during the current year. If conditions of flow have been 

reasonably permanent up to the time of the last preceding measurement, it is considered best to publish values of discharge on the basis 

of the latest verified rating curve rather than to omit them altogether, although it should be distinctly understood that such records 

are at times subject to considerable error. This is also true, although 

to a less degree, of the period of record since the date of the last 

measurement of the current year. As a rule the accuracy notes are 

based on the assumption that the rating curve used is strictly applicable to the current year.

In order to give engineers and others information regarding the

probable accuracy of the computed results, footnotes are added to the

discharge tables, stating the probable accuracy of the rating tables

 used, and an accuracy column is inserted in the monthly discharge
NORTH PACIFIC COAST. 31

table. For the rating tables "well defined" indicates in general 

that the rating is probably accurate within 5 per cent; "fairly well 

defined," within 10 per cent; "poorly defined" or " approximate/' 

within 15 to 25 per cent. These notes are very general and are based 

on the plotting of the individual measurements with reference to the 

mean rating curve.

The accuracy column in the monthly discharge table does not apply 

to the maximum or minimum nor to any individual day, but to the 

monthly mean. It is based on the accuracy of the rating, and probable reliability of the observer, and knowledge of local conditions. In 

this column A indicates that the mean monthly flow is probably 

accurate within 5 per cent; B, within 10 per cent; C, within 15 per 

cent; D, within 25 per cent. Special conditions are covered by footnotes.

USE OF THE DATA.

In general, the. policy is followed of making available for the public 

the base data which are collected in the field each year by the Survey 

engineers. This is done to comply with the law, and also for the 

express purpose of giving to any engineer the opportunity of examining the computed results and of changing and adjusting them as 

may seem best to him. Although it is believed that the rating tables 

and computed monthly discharges are as good as the base data up to 

and including the current year will warrant, it should always be borne 

hi mind that the additional data collected at each station from year 

to year nearly always throw new light on data already collected and 

published, and hence allow more or less improvement in the computed results of earlier years. It is therefore expected that the engineer who makes serious use of the data given in these papers will 

verify all ratings and make such adjustments in earlier years as may 

seem necessary. The work of compiling, studying, revising, and 

republishing data for different drainage basins for five or ten year 

periods or more is carried on by the United States Geological Survey 

so far as the funds for such work are available.

The values in the table of monthly discharge are so arranged as 

to give only a general idea of the conditions of flow at the station, 

and it is not expected that they will be used for other than preliminary estimates. The daily discharges are published to allow a more 

detailed study of the variation in flow and to determine the periods 

of deficient flow.

COOPERATIVE DATA.

Cooperative data of various kinds and data regarding the run-off 

at many stations maintained wholly by private funds are incorporated 

in the surface water-supply reports of the United States Geological 

Survey.
32 SURFACE WATEE SUPPLY, 1909, PART XII.

Many stations throughout the country are maintained for specific 

purposes by private persons, who supply the records gratuitously to 

the United States Geological Survey for publication. When such 

records are supplied by responsible persons and appear to be reasonably accurate they are verified, so far as possible, and estimated values 

of accuracy are given. Records clearly known to be worthless or 

misleading are not published. As it is, however, impossible to verify 

completely all such records furnished because of lack of funds or for 

other causes they are published for what they are worth, because 

they are of value as a matter of record and afford at least approximate information regarding stream flow at the particular localities. 

The Survey does not, however, assume any responsibility for inaccuracies found in such records, although most of them are believed 

to be reasonably good.

COOPERATION AND ACKNOWLEDGMENTS.

During 1909 the work in Oregon, Washington, Idaho, and Montana was done.under cooperative agreements between the United 

States Geological Survey and the respective States.

In this work the State is the chief beneficiary, for its interest in 

obtaining a thorough and reliable knowledge of its water resources is 

paramount. At a very moderate cost for field work the State procures the services of men already trained in collecting and analyzing 

the fundamental data, and after the material has been gathered it is 

published without additional expense on the part of the State. .

In general the cooperative agreements specify that the United 

States Geological Survey shall allot from its appropriation a sum 

equal to that appropriated from State funds; but to obtain results 

at ail commensurate with public needs it has been necessary to expend 

a much larger sum.

The United States Reclamation Service, which is a heavy investor 

in the development of the water resources of the Western States, 

has been so handicapped by a lack of physical data that it has been 

forced to expend from its own fund considerable money for investigations of this kind. The United States Indian Office also in the development of projects for the benefit of the Indians, has found it necessary to make certain investigations of water supply. As these investigations are closely allied with the collection of statistics of rain and 

snowfall, the cooperation of the United States Weather Bureau has 

been enlisted to a small extent. The engineers of the Geological 

Survey in their regular field work are able to install and inspect some 

of the rainfall stations maintained by the Weather Bureau with but 

little loss of time. Under agreements with the Reclamation Service 

and with the Office of Indian Affairs the work has been performed
NORTH PACIFIC COAST. 33

under the direction of the engineers of the Geological Survey. Careful cost accounts have been kept of this work and repayments made 

to the Geological Survey of the amounts represented.

COOPERATION IN OREGON.

In 1905, the Oregon Legislature passed an act providing for an 

annual appropriation of $2,500 for the investigation of water resources 

within the State, contingent upon an equal allotment by the United 

States Geological Survey for similar investigations. The State engineer represents the State in this cooperation and each year makes an 

agreement with the Director of the Geological Survey. The principal 

features of this agreement are:

1. The United States Geological Survey assumes the responsibility of gathering, analyzing, and publishing the data.

2. Field notes, maps, etc., and all data gathered as a result of field 

studies are at all times open to inspection of the State engineer, and 

if they are not entirely satisfactory the agreement can be terminated 

at any time.

3. Salaries of classified employees and the cost of nonexpendable 

equipment are paid from Government funds, while traveling expenses, salaries and expenses of field assistants, cost of expendable 

supplies, etc., are paid from the State funds. In this manner practically the entire amount of the State's appropriation is expended 

within the State.

4. The cost of publication is borne entirely by the Geological 

Survey.

During the calendar year 1909 the total expense for water-supply 

investigations from Government and State funds in Oregon was 

$8,606.66. This amount was distributed among the several cooperating bureaus as follows:

The inordinately high average cost of each discharge measurement 

in Oregon $52 is very simply explained. In previous years more 

funds were available and a larger number of stations were installed 

than could be maintained by the funds allotted in 1909. To avoid 

interrupting the continuity of records, the field work was eliminated 

except in that part of central Oregon where cooperative agreements 

with the Reclamation Service made it possible to continue the work; 

in the other parts of the State the money was expended for the payment of gage observers, with the expectation that when additional 

funds are available a sufficient number of discharge measurements 

can be made at these stations to enable the computation of discharge.

COOPERATION IN WASHINGTON.

The legislature of Washington passed an act in 1909 containing the 

following section:

In order to complete the topographic map of the State of Washington, and for the 

purpose of making more extensive stream measurements and otherwise investigating 

and determining the water supply of the State, there is hereby appropriated the sum 

of $30,000 for cooperation with those branches of the United States Geological Survey 

engaged in this work. This appropriation, however, shall be contingent upon and not 

become available unless the United States Government appropriates an equal amount 

to be expended for similar purposes within the State. The Board of Geological Survey 

is hereby authorized and directed to enter into such agreements with the Director of 

the United States Geological Survey as will insure that the said surveys and investigations be carried on in the most economical manner, and that the maps and data be 

available for the use of the public as quickly as possible.

The appropriation of $30,000 was for two years' work. The 

division of the amount between topographic surveys and watersupply investigations was left open to agreement. It was agreed that 

the sum of $10,000 should be expended for the former and $5,000 for 

the latter during the fiscal year 1910. In the State of Washington 

the Board of Geological Survey is made the cooperating agent. This 

board is represented by the State geologist, Henry Landes. The 

agreements entered into between the Director of the United States 

Geological Survey and the Washington State Board of Geological 

Survey were similar to that cited for the cooperative work in Oregon.

A systematic study of the available water power in Washington 

was also Ijegun under the cooperative agreement. The area to be
NORTH PACIFIC COAST. 35

investigated first is the Cascade Range and the first unit of this area 

is the southern portion. Surveys of the principal rivers draining 

that portion of the Cascade Range south of Mount Rainier were 

made during the fieldseason of 1909. River profiles were made and 

the low-water discharge of the streams determined at critical points. 

On each stream surveyed a gaging station was installed in addition 

to the temporary ones. The results from these permanent stations 

for subsequent years can be compared with those obtained at the 

temporary stations during the summer season of 1909. The results 

of these power investigations and the maps accompanying them will 

be published in special water-supply papers.1

The following tables give the cost of water resources investigations 

in the State during 1909 and the distribution of these expenses. The 

$5,000 appropriated by the State was largely used for water-power 

surveys. Agreements did not go into effect until June 1. The total 

expenditures were $13,277.54, distributed as follows:

COOPERATIVE WORK IN COLUMBIA RIVER DRAINAGE BASIN, MONT.

The work in the Columbia River drainage basin in Montana is carried on largely in cooperation with the United States Reclamation 

Service. The work is confined entirely to streams in connection with 

reclamation projects on Flathead River and its tributaries. With 

the exception of a few observers paid by the Geological Survey and 

the State of Montana, the entire cost of the work is borne by the 

Reclamation Service.

The following is a statement of the amounts and a distribution of the 

expenditures:

COOPERATIVE WORK IN IDAHO.

The State of Idaho, acting under authority given by the legislature 

of 1909 through its State land board, appropriated the sum of $2,000, 

contingent upon the expenditure by the United States of an equal 

amount, for the investigation of the water resources of the State.

On July 1, 1909, a contract was entered into between the State 

engineer, representing the State of Idaho, and the Director of the 

Geological Survey, representing, the United States. This contract 

provided for the expenditure of $2,000 by each party during the 12 

months from July 1, 1909, to June 30, 1910, for the purpose of making 

this investigation. The principal features of the contract are practically the same as those of the contract with the State of Oregon (p. 

33).

ROGUE RIVER DRAINAGE BASIN.

DESCRIPTION.

Rogue River drains an area in the southwestern corner of the 

 State of Oregon, including the extreme western part of Klamath 

County and portions of Jackson, Josephine, and Curry counties. On 

its north side are the Rogue River Mountains, on the east are the 

Cascades, and in southern part of the area is a spur of the Siskiyou 

Mountains. In all, the basin comprises 5,080 square miles.

The river is formed by three principal forks the North, Middle, 

and South which rise among the peaks of the Cascade Range and 

unite near Prospect, in Jackson County. From this point Rogue 

River winds in a general westerly direction to the ocean, which it 

enters near the town of Gold Beach, in Curry County. In the 

lower half of its course the stream hugs closely the base of the Rogue 

River Range. Its principal tributaries are shown by the following 

table:

Principal tributaries of Rogue River.

From the north and :west. From the east and south.

Middle Fork.

South Fork.

Big Butte Creek (drainage area, 268 square

North Fork.

Elk Creek.

Stewarts Creek.

Evans Creek.

Leland Creek. Little Butte Creek (drainage area, 361

square miles). 

Bear Creek (Stewarts Creek) (drainage

area, 380 square miles). 

Applegate Creek (drainage area, 606 square

miles). 

Illinois River.

The North Fork, or main stream, derives its water from springs, 

probably supplied from Crater La"ke, which lies near the center of 

Crater Lake National Park, at an elevation of 6,240 feet above sea 

level. This lake occupies the crater of an ancient volcanic mountain, 

to which the name Mount Mazama has been applied. The lake has 

no visible outlet.1 The walls inclosing it are made up of alternating

i Diller, J. S., Geology of Crater Lake National Park: Prof. Paper U. S. Geol. Survey No. 3, 1902, p. 60.
NORTH PACIFIC COAST. 47

sheets of lava, dipping away from the lake practically in all directions. 

They are porous enough to afford passage for considerable water. 

Springs around the base of the mountain are abundant. Little and 

Big Butte creeks drain the southern portion of the Crater Lake 

National Forest. Bear Creek, formerly called Stewart Creek, drains 

the famous fruit section of the Rogue River valley; Applegate Creek 

drains the Siskiyou Mountains; and Illinois River drains the territory 

to the south of the main stream near the coast, a portion of which is 

in the Siskiyou National Forest.

The drainage area is, in general, mountainous, elevations ranging 

from sea level at Gold Beach to 9,760 feet at the summit of Mount 

McLaughlin (formerly known as Mount Pitt), a snow-capped peak 

dividing the drainage of Big Butte and Little Butte creeks. The 

general elevation of the mountain range at the headwaters of the 

Rogue is 6,000 feet. Prospect is 3,000 feet, Ashland is 1,938 feet, 

and Grants Pass 956 feet above sea level.

The area is almost entirely forested. The mean annual rainfall at 

Gold Beach is 86 inches, at Grants Pass 33, at Ashland 27, on the 

headwaters of Illinois River 70, and at Crater Lake 100 inches. On 

the headwaters of the stream a large part of the precipitation during 

the winter months is in the form of snow. The rainfall is insufficient 

for the production of crops without irrigation.

Fish Lake ditch, which diverts water from Little Butte Creek, is 

the largest in operation. A number of little ditches are used to 

irrigate the narrow valley lands contiguous to the small streams. 

In this manner Ashland, Wagner, and Applegate creeks are largely 

appropriated for irrigation. It is realized that the agricultural 

resources of this section of the country will not be utilized in the 

most economic manner until irrigation is practiced extensively. The 

valley lands in the vicinity of Grants Pass along Bear Creek are 

particularly adapted to fruit culture, and the Rogue River valley 

has become justly famous for the excellent quality of its apples, 

pears, and other fruits.

The streams of this area, like others draining the Cascade Mountains, 

afford wonderful opportunities for water-power development. At 

present the only important plants are those of the Rogue River 

Electric Co. at Gold Hill and at Prospect.

Stream measurements in this basin were begun in August, 1905. 

For the four years the highest run-off values are shown by the records 

for 1907. It is probable that the lowest values would have been 

found in 1905 if records for that year had been complete.

NORTH FORK OF ROGUE RIVER AT PROSPECT, OREG.

This station was established July 17, 1907, just above the Rogue 

River Electric Co.'s dam, half a mile above Prospect, 5 miles above
48 SURFACE WATER SUPPLY, 1909, PART XII.

the junction with the South Fork, and at the head of Rogue River 

gorge. Gage readings are furnished by the Rogue River Electric Co.

The fall of the river through this gorge is to be utilized for development of water power. The data are valuable chiefly in connection 

with water-power development, but they furnish also some very 

useful information concerning the run-off from forested areas under 

the climatic conditions which exist in the southern portion of the 

Cascade Range.

No equipment has yet been installed for making measurements 

during high water, and at low water the only point available is in a 

very narrow canyon where the water is extremely turbulent and the 

velocities are most irregular.

During 1907 a vertical staff gage was used, located about 250 feet 

above the dam. Daily readings during 1908 and 1909 were made 

from a staff gage at the observer's house below the dam. This gage 

was washed out on November 23, 1909, and replaced by the observer 

December 20, 1909.

No discharge measurements were made during 1909.

A rating curve has not yet been developed for this station.

NORTH PACIFIC COAST. 49

ROGUE RIVER NEAR TOLO, OREG.

This station, which was established August 30, 1905, is located 

just below the dam of the Eogue Eiver Electric Co.'s power plant 

at Gold Ray, Oreg., 1J miles below Tolo, Oreg., and below the confluence of Bear Creek.

The staff gage is fastened to a pier of the highway bridge about 

250 feet below the dam and below the tailrace of the power house. 

It is about 300 feet upstream from the cable measuring section.

The data obtained at this station are of value in connection with 

the use of the river for water-power development and its proposed 

use for extensive irrigation, a number of large canals being already 

under construction.

The flow at this station is affected by the operation of the power 

plant. The velocity of the water at the measuring section is swift 

and the channel rough, and although conditions are apparently 

permanent it has been impossible to develop a permanent rating 

curve. The records, particularly those taken at low water, are not 

as accurate as could be desired.

No discharge measurements were made during 1909. The station 

was last inspected December 29, 1908, and the accuracy of the daily 

and monthly discharges given below depends on the permanency of 

conditions of flow and of the elevation of the gage since that date.

Daily gage height, in feet, of Rogue River near Tolo, Oreg., for 1909.

LITTLE BTTTTE. CREEK NEAR EAGLE POINT, OREG.

Little Butte Creek is formed near Lake Creek in Jackson County, 

by the union of its North and South forks, the united waters flowing 

westward and joining Rogue River about 3 miles east of Table Rock.
NORTH PACIFIC COAST. 51

This stream is used to a large extent for irrigation, and additional 

developments are under way. It also furnishes a water supply for 

the city of Medford. It is practically the only available source of 

water for complete irrigation of the upper Eogue River valley. This 

valley is drained directly by Bear Creek, and comprises about 60,000 

acres of agricultural land, nearly all of which is susceptible of intensive agriculture. Fine fruits constitute the most remunerative product of the farm, and this valley has become justly famous for the 

excellent quality of its apples and pears.

The gaging station was established July 13, 1907. It is located at 

Tronson & Guthrie's fruit ranch, 1 mile above Eagle Point, about 2 

miles above the mouth of Antelope Creek, and above the head of a 

ditch which diverts water for milling at Eagle Point.

A number of small ditches divert water from the stream above the 

station, so that the flow here obtained does not wholly represent the 

natural run-off from the drainage area.

The following discharge measurement was made by A. P. Stover:

September 17, 1909: Gage height, 0.75 feet; discharge, 37.1 second-feet.

Daily gage height, in feet, of Little Butte Creek near Eagle Point, Or eg., for 1909. 

[Tronson & Guthrie, observers.]

BEAR CREEK AT TALENT, OREG.

Bear Creek, formerly known as Stewart Creek, rises in the southeastern part of Jackson County, and flows northwestward to its junction with Eogue River near Tolo. Its entire drainage area comprises 

380 square miles.
NOKTH PACIFIC COAST. 53

The gaging station was established July 11, 1907, at a county highway bridge at Talent, Oreg., 500 feet above the head of a power and 

irrigation canal which diverts water from the left bank, about half a 

mile below the mouth of Wagner Creek and 1 § miles above the mouth 

of Anderson Creek. The vertical staff gage is attached to the bridge 

from which discharge measurements are made.

The stream is used largely for irrigation, and the data obtained at 

this station are useful in that connection. Any increase of irrigation 

development from this stream will require the construction of storage 

reservoirs.

The conditions are not favorable for good results. The bed of the 

stream is somewhat changeable, and without a large number of gagings each year only the merest approximation to actual discharges can 

be secured. No discharge measurements were made during 1909.

Daily gage height, in feet, of Bear Creek at Talent, Oreg.,for 1909.

APPLEGATE CHEEK AT MTJBPHY, OBEG.

Applegate Creek rises in the Siskiyou Mountains in the northwestern part of Siskiyou County, Cal., flows northeastward into Jackson County, Oreg., for about 20 miles, then turns to the northwest 

and unites with Rogue River about 8 miles west of Grants Pass in 

Josephine County. Its drainage area comprises 606 square miles.
54 SURFACE WATER SUPPLY, 1909, PART Xll.

The gaging station was established July 22, 1907, at a county highway bridge at Murphy, Oreg., 8 miles above the mouth of the creek 

and 7 miles from Grants Pass.

The vertical staff gage is on the right bank 250 feet below the bridge 

from which discharge measurements are made. The gage datum 

has remained the same.

The data obtained at this station are needed in connection with the 

use of the stream for irrigation, mining, and the development of water 

power. Small ditches are numerous in the vicinity of the station, 

but most of them serve only a single farm. It has been observed 

that since early irrigation has been practiced the summer flow of the 

stream at this point is more uniformly maintained than before.

The conditions at the station are not favorable for very good results. 

The height of the water is affected in an irregular manner by a brush 

dam about 600 feet below the gage. It is washed away, either 

wholly or in part, with every rise in the creek, even during irrigating 

seasons.

No discharge measurements were made during 1909, and estimates 

of discharge are withheld until more data have been obtained.

Daily gage height, in feet, of Applegate Creek at Murphy, Oreg., for 1909.

South Fork is also formed by two forks the northern rises in Old 

Bailey Mountain about 4 miles south of Diamond Lake, and the 

southern on the northern slope of Abbot Butte and flows westward 

^nd northward. From the junction of its principal forks, Umpqua 

River takes a tortuous but in general northerly course to Elkton, 

beyond which its course is more nearly west until it empties into the 

Pacific Ocean at Winchester Bay, in the northwestern part of Douglas 

County. Its total drainage area comprises about 4,000 square miles. 

At Scottsburg, just above tidewater, the area measures 3,070 square 

miles. The North Umpqua drains 1,080 and the South Umpqua 1,990 

square miles. The important tributaries of the Umpqua are Smiths 

River, which drains the low mountainous area near the coast;- Elk 

Creek, which drains the divide between the Umpqua and Willamette 

basins; Cow Creek, which drains the divide between Rogue River 

and the Umpqua drainage basin; and the North and South forks.

The country is rough and mountainous, and the streams flow in 

comparatively narrow valleys bordered by narrow stretches of agricultural land. The general elevation of the headwaters is 6,000 feet, 

with a few snow-capped peaks 8,000 to 10,000 feet high. As the 

elevation at Roseburg is 485 feet above sea level, it is apparent that 

the North Fork falls nearly 3,800 feet in the 75 miles from Diamond 

Lake to Roseburg by the river channel. The lower portion of the 

Umpqua has comparatively little fall, as is evidenced by the very 

winding character of the stream.

The region is one of the most densely forested in the United States, 

and probably 80 per cent of the drainage area can be classed as 

heavily forested. About one-fourth of the forest area is included 

in the national forests; the rest is owned by corporations and individuals.

The mean annual rainfall at Roseburg is 30 inches; at Drain, near 

the divide between the Willamette and Umpqua drainage basins, it is 

48 inches. The mouth of the stream probably receives as much as 

60 inches per annum, while at the headwaters the precipitation is 

100 inches or more. Except on the headwaters, all of this falls as 

rain during the nine months of the year from September to May.

Little or no irrigation has been practiced in the Umpqua Valley, 

although a few small ditches take water from the smaller creeks

tributary to the North and South forks. The agricultural products 

consist of grain and fruits. For the production of apples, prunes, 

and similar fruits, the climate and soil are especially well adapted. 

Although the opportunities for water-power development in this area 

are almost phenomenal, there are no plants of importance.

SOUTH FORK OF UMPQUA RIVER, NEAR BROCKWAY, OREG.

This station, which was established December 6, 1905, is located 

just below Winston's highway bridge, 6 miles south of Roseburg and 

3 miles east of Brockway, Oreg., 3 miles below the mouth of Lookingglass Creek, 10 miles below the mouth of Myrtle Creek, and 7 miles 

above the confluence of the North and South forks of Umpqua 

River.

The data obtained at this station are of particular interest in 

studying the run-off from forested areas and are of practical use for 

economic development of the water resources of this region.

The staff gage consists of an inclined low-water section, on the 

right bank, and a vertical high-water section, originally located at 

the cable section about 300 feet below the highway bridge, to which 

it was transferred January 14, 1907.

Discharge measurements were originally made from a cable, but 

this was destroyed by flood January 4, 1907. Since this date the 

highway bridge has been used. The gage datum has remained unchanged.

The conditions at this station are favorable for good results, and a 

permanent rating curve has been established. There is never any 

ice at this station. No discharge measurements were made in 1909.

UMPQUA RIVER, NEAR ELKTON, OREG.

This station, which was established October 18, 1905, by J. G. 

Kelley, of Portland, through whose cooperation the station is maintained, is located at Smiths Ferry at the falls in the river 4 miles 

above Elkton, Oreg. No important tributaries are received by the 

river in the vicinity of the station, the nearest being Elk Creek, 3 

miles downstream.

The data obtained here are valuable chiefly in connection with 

water-power development, but they are also of considerable scientific 

interest, in that they determine run-off factors for large areas heavily 

forested and under heavy rainfall.

The inclined gage is 100 feet above the ferry on the left bank. 

The conditions at the station are favorable for good results. The 

channel is fairly permanent. The banks are high and do not overflow, although the river is subject to enormous floods. The datum 

of the gage has not been changed since it was established, but the 

gage heights have not been observed with any degree of refinement.

No discharge measurements were made during 1909.

NOTE. These discharges are based on a rating curve that is well denned between 1,100 and 13,000 secondfeet. The rating table above 8,500 second-feet is the same as that published in Water-Supply Paper No. 

252, p. 52. Discharges Aug. 8 to 31, Sept. 2 to 26, and Oct. 10 to 17 are estimates, based on comparisons 

of hydrographs for other stations in Umpqua River basin.

NORTH FORK OF UMPQUA RIVER AT WINCHESTER, OREG.

The station, which was originally established September 6, 1905, 

at Dixon's farmhouse 10 miles below the mouth of the East Fork of 

the North Fork, 3 miles west of Oak Creek, Oreg., and 9 miles northeast of Roseburg, Oreg., was moved on November 10, 1908, to the 

Southern Pacific Railroad bridge at Winchester, Oreg., about 6 

miles north of Roseburg and 6 miles above the mouth of the stream. 

As no important tributaries enter between these points the records 

are comparable.

The present staff gage is in three sections, and is fastened to the 

left pier of the railroad bridge from which discharge measurements 

are made. The gage is about 600 feet below a power plant and 

about 1,200 feet below a highway bridge from which high-water 

measurements can be made.

During 1909 both the middle and high-water sections were washed 

out at different times but were replaced at the same datum. Readings during these periods were obtained by measuring down from the 

base of the rail and were later corrected to agree with the datum of 

the gage.

The stream is subject to sudden floods, caused usually by chinook 

winds in the spring or fall, by which the snows on the headwaters of 

the stream are rapidly melted.

The records obtained at this point furnish data of considerable 

value in connection with water-power development and irrigation, 

for which the waters of the river will probably be used to some extent. 

The data have also much scientific value, as the studies of this stream 

and of the South Fork afford some very interesting information concerning the run-off from forested areas.
NORTH PACIFIC COAST. 61

No discharge measurements were made during 1909.

MILL CHEEK NEAR ASH, OREG.

This station, established May 29, 1909, is at the outlet of Loon 

Lake, in the lower Umpqua River basin, in T. 23 S., R. 10 W., 

near Ash, 12 miles south of Scottsburg, Oreg. It is reached by stage 

from Drain, Oreg.

The staff gage is on the south shore of the lake about three-fourths 

of a mile above the outlet and near the observer's house. Discharge 

measurements are made by wading at the lower end of a pool just 

below the outlet of the lak£. The gage heights have been furnished 

by J. G. Kelley, of Portland, Oreg.

The data are of value chiefly in connection with the development 

of water power. The stream has a heavy grade below the station, 

and Loon Lake offers a possible site for storage.

No discharge measurements were made during 1909. On account 

of the effect of wind the lake heights can not be used for determining 

the minimum discharge during the low-water season, but they can 

be used to determine the total run-off when sufficient discharge 

measurements have been obtained.

SILETZ RIVER DRAINAGE BASIN. 

DESCRIPTION.

Siletz River rises in the mountains in the western part of Polk 

County, Oreg., at an elevation of about 3,000 feet above sea level, 

flows in a general southwesterly direction to Siletz in Lincoln County, 

and thence winds tortuously northward and westward until it enters 

the Pacific Ocean through Siletz Bay, about 6 miles northwest of 

Kernville. Its total length is approximately 50 miles, and its drainage area measures 320 square miles.

The basin is densely timbered throughout, although some areas 

of logged-off lands may be found on the lower reaches of the stream.

The mean annual rainfall at the mouth of the river is 75 or 80 

inches; at the headwaters it is undoubtedly as high as 150 inches. 

The annual run-off shows about 9 second-feet per square mile of 

drainage area. The records thus far shows very little variation in 

the total run-off of this drainage area.

- SILETZ RIVER AT SILETZ, OREG.

This station was established November 25, 1905, about 1 mile 

above Siletz Ferry at Siletz, Oreg., near the Siletz and Toledo stage 

road, 9 miles north of Toledo and 6 miles below the mouth of Rock 

Creek.
NORTH PACIFIC COAST. 63

The data collected are chiefly of scientific interest, as the river is 

fairly typical of the short streams draining the western slope of the 

Coast Range and the run-off factors obtained here are doubtless 

applicable to other streams similarly located. The records are also 

of value in connection with a possible power development near Siletz.

The staff gage is near the cable equipment. The gage datum has 

not been changed. The stream is subject to sudden and violent 

floods, and as the gaging station is somewhat inaccessible it has been 

impossible up to the present time to secure high-water measurements. The records for medium stages are reliable but are uncertain at low stages.

No discharge measurements were made during 1909. The cable 

was washed away during the flood of November 22, 1909, and has not 

been replaced.

COLUMBIA RIVER DRAINAGE BASIN.

DESCRIPTION.

Columbia River has its source in Columbia Lake, in the eastern division of the Kootenai district, in British Columbia. From Columbia 

Lake it flows north to the fifty-second parallel of latitude, turns
64 SUEPACE WATEK SUPPLY, 1909, PAET XII.

abruptly southward, nearly paralleling its former course, flows 

through a series of narrow lakes, and crosses the international boundary line near the northeast corner of the State of Washington, where 

it receives Clark Fork. After traversing Washington in a general 

southerly direction, it turns westward and forms the boundary lines 

between Washington and Oregon, and empties into the Pacific Ocean 

at the forty-sixth parallel of latitude.

The total drainage area of the Columbia is estimated from the best 

available maps to be 259,000 square miles, divided as follows:

Area of Columbia River drainage basin.

Wyoming.................................................... 5, 270

British Columbia.............................................. 38, 700

This area is limited on the east by the Rocky Mountains and is 

traversed north and south by the Cascade and Coast ranges. Between the mountain ranges are rolling, rough, and mountainous tablelands. Mean altitudes range from sea level near the mouth of the 

river to 8,000 feet in the Rocky Mountains, 5,000 feet in the Cascade 

Range, 1,000 to 4,000 feet in the intervening table-lands. Many peaks 

in the mountain ranges extend into the region of eternal snow, the 

highest in the Cascade Range, including Mount Baker (10,827 feet), 

Mount Rainier (14,360 feet), Mount Adams (12,307 feet), Mount 

Hood (11,225 feet), and Mount Jefferson (10,200 feet).

The principal tributaries of Columbia River from the source to 

the mouth are listed in the following table:

The river is navigable in long stretches throughout its course in 

the United States, but owing to rapids and falls continuous navigation is not possible in the natural condition of the river. The navigable waters of the Columbia and its tributaries aggregate a total of 

2,136 miles, distributed as follows:

The improvement of this river system for navigation is being carried on as rapidly as funds will permit. The work at present under 

way consists, briefly, of the deepening of the mouth of the Columbia 

River through the construction of jetties. It is expected that when 

projects now under way are completed a depth of 40 feet may, if 

necessary, be obtained. The opening of the Cascade locks and 

canals to traffic in 1896 rendered the river navigable in one unit from 

the mouth to Big Eddy. When the projected locks and canal have 

been constructed around the obstructions between Celilo and Big 

Eddy, a distance of about 8J miles, the Columbia will be open to 

steamboat navigation from Priest Rapids to the-sea a distance of 

400 miles.

The area drained by the Columbia includes perhaps the largest 

consolidated area of forests in the world. Originally almost the 

entire area, except those arid portions midway between the mountain 

ranges, was covered with dense forests, and although the territory 

has been settled for about 65 years and large areas have been cleared, 

the ratio of forested area to the entire area has been reduced but 

slightly.

The rainfall is distributed over the area most irregularly. From 

the Pacific coast eastward to the summit of the Coast Range the 

mean annual rainfall varies from 100 to 150 inches. In the basins 

between the Coast and Cascade ranges, it drops to about 40 inches 

per annum. It increases again to about 100 inches on the summit of 

the Cascade Range, and decreases very rapidly beyond the summit, 

until at the eastern base of the Cascades it has dropped to about 14 

inches. At the mouth of Snake River the mean annual rainfall is 

about 9 inches, but this extremely low rainfall obtains only in the 

lower altitudes. Beyond this point the rainfall again increases in 

Washington and northern Idaho to about 20 inches, while in eastern 

Oregon it continues at about 9 inches or less. In the eastern areas 

a large proportion of precipitation appears as snow, and during the 

winter months the streams are more or less icebound. West of the
NORTH PACIFIC COAST. 67

Cascade Range, however, the winter stream flow is not affected 

by ice.

The climate of the area exhibits all the variations from the rigorous climate of the northern latitudes, as found in British Columbia 

and the higher table-lands of Oregon and Idaho, to the mild climate 

of western Oregon and Washington.

As regards agriculture, the area ranges from the extremely arid 

region, where irrigation is absolutely essential, through the semiarid 

country, where dry farming and irrigation are practiced side by side, 

to the humid country that, strictly speaking, is arid in the summer 

months. In the Willamette Valley, for instance, where the mean 

annual rainfall is approximately 40 inches, only 5 per cent of this 

amount is received during the growing season, and the fullest agricultural development will not be realized until this entire portion of 

the area is under the irrigation ditch as completely as are the arid 

portions beyond the mountains. The irrigated areas of the Pacific 

Northwest are being extended so rapidly that it is almost impossible 

to keep pace with the development, and yet, comparatively speaking, 

a very small portion of the irrigable area has been developed. At 

present 1,500,000 acres of land are under irrigation in the Northwest, 

and this area will be more than doubled when projects now being 

constructed are completed. The values of irrigated agricultural 

lands vary from about $30 per acre for the poorest qualities of hay 

lands to $3,000 per acre for the intensely cultivated orchards.

Columbia River and its tributaries afford at least one-third of the 

available water powers in the entire United States, but developments 

along this line have scarcely begun. About 150,000 horsepower are 

at present developed by water power in Oregon, Washington, and 

Idaho.

Lumbering has been the principal industry of the Northwest, and 

the streams of the country have therefore been used not only for 

water-power development but for the transportation of logs from the 

timbered mountain slopes to the mills and factories in the valleys 

below. Comparatively few streams, however, carry sufficient water 

during the summer months, and it has been necessary to build temporary dams on a large number of streams, where the logs are stored 

until released by opening the gates in the dam. The "splash" thus 

caused usually suffices to carry the logs to their destination.

The highest recorded flood in Columbia River occurred in June, 

1894. The highest floods on the tributaries are invariably caused by 

the " chinook" a warm wind, usually accompanied by rain, occurring in the spring and fall. The fall "chinook" usually brings the 

highest waters, as it may occur immediately after a heavy snow has 

covered the mountain ranges. The Columbia itself is not greatly 

affected at such times.
68 SURFACE WATER SUPPLY, 1909, PART XII.

The following special reports contain information regarding the 

surface waters of Columbia River basin:

Water-Supply Paper 253, Water powers of the Cascade Range, Part I, southern 

Washington, contains stream flow data and river profiles on rivers in Klickitat, White 

Salmon, Little White Salmon, and Lewis River drainage basins.

Supplement to First Biennial Report of the State Engineer of Oregon, 1906, contains 

all data on Oregon streams, compiled from published records of the United States 

Geological Survey.

COLUMBIA RIVER NEAR PASCO, WASH.

This station was established October 15, 1904, at the Northern 

Pacific Railway bridge near Pasco, Wash., 4 miles above the mouth 

of Snake River and 7 miles below the mouth of Yakima River.

One discharge measurement has been made at this station. The 

gage heights are complete. Future measurements are needed to 

develop a rating curve to which the gage heights can be applied.

Since September 1, 1908, the records have been furnished by the 

United States Weather Bureau. The gage datum used by the 

United States Geological Survey is 307.75 feet above sea level; the 

datum of the Weather Bureau gage is 10 feet higher. The gage 

heights published below are referred to the Survey datum.

NORTH PACIFIC COAST. 69

COLUMBIA RIVER AT THE DALLES, OREG.

This station is located 2,000 feet below the ferry at The Dalles, 

Oreg., and is below the mouth of Deschutes River and above Hood 

and Klickitat rivers.

There are two gages at The Dalles, the Government, or Brooks 

gage, used by the United States Geological Survey, made up of several sections attached to piling of the viaduct connecting Regulator 

Dock with the warehouse; and the United States Army engineer's 

gage, which is similar but has a datum 8.9 feet lower than the 

Brooks gage.

Discharge measurements are made from a gasoline launch held in 

position by a cable sagging into the water in order to allow the passage of river steamers. The cable is stretched at time of each measurement.

A comparison has been made between the gage readings at The 

Dalles and those taken at Cascade Locks, 20 miles down the river, at 

which point the gage records are nearly complete for 30 years. The 

elevation of the gage datum at The Dalles is 45.6 feet and at Cascade 

Locks 42.5 feet above sea level.

When the locks were formally opened in 1896 the gage was moved 

and a datum 6 feet lower was used until December 31, 1899. The 

condition at the locks are such that a permanent rating is perfectly 

feasible.

Records of gage heights have been kept at The Dalles by the United 

States Weather Bureau since 1892. A number of measurements 

were made in 1903 by the United States Army engineers. In 1907 

and 1908 measurements were made by the United States Geological 

Survey, and these in connection with earlier measurements fully 

develop the discharge curve. 1

No discharge measurements were made in 1909.

NOTE. These discharges are based on a ratine; curve that is well defined between 69,000 and 740,000 second-feet. The curve is the same as that used in computing the 1892 to 1908 data, Water-Supply Paper 

No. 252, p. 71.

As a result of an ice jam, Jan. 11 to 27, the daily discharges are abnormally low during the first part of 

this period. The rise of Jan. 20 to 26 was caused by heavy rains in Oregon.

Daily discharges Jan. 30 to Feb. 3 interpolated.

CLARK FORK DRAINAGE BASIN. 

DESCRIPTION.

Clark Fork of Columbia River rises in the Silverbow Mountains, 

Montana, about 18 miles southwest of Butte. For about 40 miles it 

flows northward, but near Garrison, Powell County, it turns to the 

northwest and maintains this general course through a distance of 

about 125 miles until it reaches St. Regis, in Missoula County, where 

it turns abruptly to the northeast. At Paradise, in Sanders County, 

it resumes its northwesterly course, passing between the Cceur d'Alene 

and Cabinet ranges, crossing the "panhandle" of Idaho in Bonner 

County, flowing through Lake Pend Oreille, and entering Washington at Newport in Stevens County. From Usk to the international 

boundary line its course is northward, and just beyond the boundary 

it turns directly west to its junction with the Columbia just inside 

Canadian territory. From source to mouth its length, exclusive of 

windings, is, roughly, 420 miles, and its drainage area measures 

25,800 square miles. To the river thus described various names have 

been applied 1 and may still be used locally.

The General Land Office maps of Montana, Idaho, and Washington 

on which the Clark Fork drainage area is shown indicate more than 

150 tributary streams, but by far the greater number of these are very 

short, and scarcely a dozen can be called rivers. The most important 

are listed in the table following.

1 Clark Fork; river in Idaho, Montana, and Washington. (Not Bitter Root, Bitterroot, Clarke, Clarks 

River, Deer Lodge, Deerlodge, Hell Gate, Hellgate, Missoula, Silver Bow, nor Silverbow.) See Third 

Report U. S. Board Geog. Names, 1907, p. 51.

Bitterroot in this decision refers to a portion of the main stream so called, and not to the tributary known 

as Bitterroot River.

From the north and east.

Little Blackfoot River.

Salmon River (British Columbia).

The river leaves the Silverbow Mountains near the Continental 

Divide at an elevation of about 5,000 feet above sea level and flows 

through a valley 3 or 4 miles wide, bounded by rolling hills. At Garrison it is 4,300 feet above sea. From Garrison the valley gradually 

narrows to a mile or less at Missoula (elevation 3,200 feet), broadens 

out just west of Missoula near the mouth of the Bitterroot, and again 

narrows as the river approaches the Mission Range. Many of the 

peaks in this range exceed 8,000 feet in altitude. At Paradise the 

stream is about 2,500 feet above sea level, and at Pend Oreille Lake 

the elevation is 1,900 feet. Its course through Washington and 

British Columbia is in a deep canyon bordered in places by narrow 

benches. Through the unsurveyed portion in Washington this canyon is wild and picturesque. The river has many rapids and falls, 

and in places the rocky gorge is narrow enough to be spanned by foot 

logs. The stream falls nearly 500 feet in the last 40 miles of its 

course. The elevation of Boundary is 1,346 feet.

A great deal, of snow lies in the mountains from November to June, 

and many of the streams are frozen over in the colder months. During the greater part of the year, however, the streams are open, because of the milder climate on the western slope of the Continental 

Divide.

Irrigation in the Bitterroot Valley has been developed quite extensively. A large private enterprise near Hamilton is now completed. 

The United States Reclamation Service is irrigating the Flathead 

Indian Reservation by diverting water from the smaller streams. A 

project to dam Flathead River and develop power for pumping water 

from the lake is now under way. One hundred thousand acres will 

be irrigated on the Flathead.

Reservoir sites available for storage are numerous. The Mission 

Range has several that will be used by the Reclamation* Service; also 

good storage-reservoir sites are to be found on the Bitterroot and 

upper Little Bitterroot.

The drainage basin contains many valuable power streams. On a 

few streams power plants have already been installed and more are 

under construction. The lower 20 miles of the main river offers some 

exceptional opportunities for power developments in large units.

The run-off.records extend back to 1898. During this period, 1899 

was the wettest year and 1905 was the driest.

CLARK FORK AT NEWPORT, WASH.

A station on Clark Fork was established at. Priest River, Idaho, 

June 26, 1903, but was discontinued April 30, 1905. The gage was 

located 1,000 feet downstream from Priest River railroad station 

and one-fourth mile below the mouth of Priest River.

Gage records were begun at Newport, Wash., by the United States 

Weather Bureau in April, 1904, and they have been continuous from 

that date, except for the months of December, January, and February. The winter records are complete for 1903 to 1906.

The Weather Bureau gage is attached to the dock of the Pend 

Oreille River Navigation Co. on the left bank of the river.

High-water sections are set in line with each other at several locations on the river bank.

Gage heights are furnished by the United States Weather Bureau.

By comparing simultaneous gage readings at Priest River and Newport from April, 1904, to April, 1905, a very satisfactory relation has 

been established.

The results of this study, including discharge measurements, rating 

table, and monthly discharge from 1904 to 1908, were published in 

Water-Supply Paper 252, pages 85-89.

No discharge measurements were made in 1909, but the conditions 

are practically permanent and good results have been obtained.

NORTH PACIFIC COAST.

CLARK FORK AT METALINE, WASH.

This station is located at the town of Metaline, and was established

November 4, 1908, by Ham, Yearsley and Ryrie, of Spokane. The

gage is in two sections and is graduated in feet and tenths, one

section from zero to 32 feet and the other from zero to 10 feet.

Observations are taken twice daily. The data are of importance in

connection with water-power development. The city of Spokane is

to examine the feasibility of a municipal lighting plant near Metaline.

The following discharge measurement was made by H. L. Frazer:

October 23, 1908, gage height 1.5 feet, discharge 12,100 second-feet.

Daily gage height, in feet, of Clark Fork at Metaline, Wash., for 1908.

FLATHEAD RIVER DRAINAGE BASIN. 

DESCRIPTION.

Flathead River rises on the western slope of the Continental Divide 

in the southeastern part of British Columbia and takes a general 

southerly course, passing through Flathead Lake to Dixon, Mont., 

where it turns abruptly and flows westward to its junction with Clark 

Fork, about 3 miles southeast of Paradise. It is a large stream with 

a number of important tributaries, chief among which may be mentioned the Middle and South forks,, which rise in the Rocky Mountains, in the Lewis and Clark National Forest, flow northwestward, 

the Middle Fork uniting with the main stream about 6 miles southwest of Belton and the South Fork near Columbia Falls; Stillwater 

River, which enters near Kalispel; Swan River, which comes into 

Flathead Lake; Little Bitterroot River, which drains the northwestern part of the Flathead Indian Reservation; and Jocko River, which 

drains the southeastern part of the reservation.

The valleys of the Middle and South forks and the main stream 

above Columbia Falls are very mountainous, but from Columbia Falls 

to the lake the valley is broad and fertile, and the stream is sluggish. 

Below the lake the river traverses the Flathead Indian Reservation, 

with its wide expanse of irrigable land. The river is not subject to 

sudden fluctuations in volume, as the lake serves to regulate its flow.

FLATHEAD RIVER ABOVE FLATHEAD LAKE.

In order to determine the relative height and slope of Flathead 

River above Flathead Lake at different stages three gages were established April 24, 1909.

The upper gage is located across the river from the steamboat 

landing at Demersville, Mont., 3 miles below Kalispel, Mont. The 

second gage is located near the ranch buildings of F. N. Damon, 10 

miles below Kalispel and 7 miles below Demersville. The third is 

at Keller's ranch, 1 mile above Holt, 16 miles below Kalispel and 

about 6 miles above the point where it enters Flathead Lake. The 

zeros of the three gages are each 2,800 feet above sea level. As the 

current at these gages is sluggish, .the river freezes entirely over 

during the winter months.

Daily gage height, in feet, of Flathead River at Demersville, near Kalispel, Mont., for 1909.

NOTE. Ice not reported at this station. Probably same as at Kalispel, Dec. 4 to 31. 

FLATHEAD LAKE AT POLSON, MONT.

This station, which was established August 23, 1908, is located at 

the steamboat dock at the town of Poison, Mont. Poison is at the 

southern extremity of the lake, 35 miles north of Ravalli, on the 

Northern Pacific Railway, and about the same distance south of 

Kalispel.

The records show the fluctuation of the lake at different periods of 

the year and are of value in connection with the irrigating of the 

Flathead Indian Reservation. The gage is of the ordinary staff type 

reading from 77 to 94 feet. It is nailed to the middle piling at the 

extreme end of the steamboat pier. Gage datum is 2,800 feet above 

sea level.

NOTE. Add 2.800 feet for sea-level elevation. Ice conditions at this station not reported. 

FLATHEAD RIVER NEAR POLSON, MONT.

This station was established July 23, 1907, at Michels Ferry, 8 

miles below Poison. In the vicinity of the station the river has a fall 

of 240 feet in 6 miles. In 1909 the mean discharge was 11,800 secondfeet, and as it is possible to equalize the flow, an enormous amount 

of power can be developed.
80 SURFACE WATER SUPPLY, 1909, PART XII.

At the Newell dam site, located by the United States Reclamation 

Service, the stream flows from a narrow canyon whose bounding 

cliffs reach a great height. It is proposed to utilize the power for a 

pumping project to irrigate the lands of the Flathead Indian Reservation. There are no diversion canals taken from the river. The 

chain gage is located on the right bank just above the ferry. Its datum 

has not been changed since the station was first established, and 

estimates obtained at this station are excellent, as there is no appreciable change in the channel. Gaging conditions are little affected 

by ice, and good winter records are obtained. All measurements are 

made from car on ferry cable.

LITTLE BITTERROOT CREEK DRAINAGE BASIN.

DESCRIPTION.

Little Bitterroot Creek rises in Little Bitterroot Lake, near Marion, 

Mont., flows in a general southeasterly direction, and unites with 

Flathead River 12 miles north of Dixon. It is about 50 miles long, 

has numerous small tributaries, and drains an area of about 600 square 

miles. Several reservoir sites have been surveyed in the upper part 

of the stream, about 15 miles above the gaging station. Near Hubbart the stream has a sheer fall of about 50 feet and is bounded by 

high cliffs.

LITTLE BITTERROOT CREEK NEAR HUBBART, MONT.

The station on Little Bitterroot Creek was established April 22, 

1909, in a box canyon just below the falls, 1^ miles from Hubbart 

post office and 15 miles south of Marion, but because of the poor 

gaging conditions the station was moved October 17 to a point about 

1 mile above the former location, 1^ miles west of the ranch buildings 

of the Hubbart Cattle Co. and just above the canyon leading to the 

second fall of the Little Bitterroot.

Data obtained at this station will be used in connection with irrigation projects on the Flathead Indian Reservation.

A few small streams enter the creek above the station, but the 

principal source of water supply is Bitterroot Lakes. A few ditches 

divert water near the headwaters of the stream. The staff gage at 

the new station has a new datum. All measurements are made by 

wading. The stream freezes over at the gage in winter. Records 

of stream flow so far obtained are only fair.

LITTLE BITTERROOT CREEK NEAR DAYTON, MONT.

This gaging station, which was established April 18, 1908, at McDonald's ranch, is located near Dayton, Mont., 12 miles north of the 

Warm Springs, on the Flathead Indian Reservation. The records 

will be used by the United States Reclamation Service to determine 

the amount of water available for irrigating portions of Little Bitterroot Valley. Above the station a few small tributaries add to the 

volume of the creek and several ditches take water from it. The 

water is not all appropriated.

A staff gage is nailed to a piling of the foot bridge just back of the 

observer's house. At most stages measurements can be made to an 

advantage from this foot bridge.

CROW CREEK DRAINAGE BASIN.

DESCRIPTION.

Crow Creek rises in the eastern part of the Flathead Indian Reservation and flows in a generally southwesterly direction, entering Flathead River about 3 miles below the mouth of the Little Bitterroot.

CROW CREEK NEAR RONAN, MONT.

This station, which was established September 21, 1906, for the 

purpose of obtaining data for use in connection with a project to 

irrigate the Flathead Indian Reservation, is located about 4 miles 

south of Ronan, Mont., at the highway bridge on the stage road from 

St. Ignatius to Ronan. Investigations in connection with this project have been carried on by the United States Reclamation Service 

since the summer of 1907.

No important tributaries enter the creek above the station and no 

Water is diverted. Mud and Spring Creeks empty into Crow Creek 

several miles below. The current is very sluggish and during the 

winter months the discharge is affected by ice. A staff gage is nailed 

to the bridge pier on the left bank. Its datum has not been changed 

since the station was established.

This station affords good conditions for obtaining accurate discharge data as the channel does not change appreciably except during 

flood stages.

High-water measurements are made from the bridge, but in low 

water better results may be obtained by wading.

MUD CREEK NEAR RONAN, MONT.

Mud Creek rises about 6 miles southeast of Flathead Lake and

flows southwestward into Crow Creek.

The gaging station was established April 17, 1908, on Jeffrey's 

ranch, 3 miles northwest of Ronan, Mont., to obtain data for use 

by the United States Reclamation Service on the Flathead project.

The staff gage is nailed to a post driven in the ground just above a 

foot log from which measurements are made. The Pablo ditch, which 

takes water from the creek about 200 feet below the gage, is the only 

diversion of importance.

As the velocity is sluggish it is difficult to obtain accurate results.

MISSION CREEK DRAINAGE BASIN.

DESCRIPTION.

Mission Creek rises in the western slope of the Mission Range and 

flows in a general northwesterly direction into Flathead River about 

3 miles above Dixon. The only important tributaries are Dry and 

Post creeks, which enter Mission Creek just above St. Ignatius.

MISSION CREEK NEAR ST. IGNATIUS, MONT.

This station, which is located opposite the home of A. A. Booke, 

about 1 mile downstream from St. Ignatius, was established Septem 

ber 21, 1906, to obtain data for use in connection with water-power 

and irrigation projects. Two or three small ditches, which are used 

to irrigate about 800 acres near St. Ignatius Mission, divert water 

above the gage.

A few miles above the station where the stream flows out from 

mountains it has a fall of nearly 1,000 feet and affords an excellent 

opportunity for water-power development.

The staff gage was washed out July 5, 1907, and on July 24 a new 

gage was installed a short distance downstream and with a datum 

0.30 foot lower; on January 25, 1908, this gage was lowered 0.39 

foot. The gage was again destroyed by high water June 7, 1908, and 

was replaced June 26, 20 feet farther downstream at a different 

datum. Discharge measurements are made by wading near the 

gage..

The current is swift and the records of flow are but little affected 

by ice during the winter months. The channel shifts during high 

water, but at ordinary stages the conditions for obtaining accurate 

discharge data are good.

DRY CREEK NEAR ST. IGNATIUS, MONT.

Dry Creek rises on the western slopes of the Mission Range, in the 

southeastern part of the Flathead Reservation, and flows northwestward into Mission Creek.

The gaging station, which was established April 16, 1908, to 

obtain data for use in connection with a project to irrigate land in 

Mission Creek Valley, is located opposite Fellsman's ranch, about 

3^ miles southeast of St. Ignatius. The creek is the outlet of St. 

Marys Lake, which will be used as a reservoir to store the entire 

flow of the stream.

The current is swift. The bed of the stream is composed of coarse 

gravel and bowlders. Measurements are made by wading near the 

staff gage. No change in gage datum has been made. At low and 

medium stages none of the water reaches Mission Creek, and during
NORTH PACIFIC COAST.

the winter and early spring ceases to flow at the gage. Above the 

station one small ditch diverts water for irrigation. The only 

tributary is a small creek which enters from the right a short distance below the station. The conditions are fair for obtaining accurate discharge data.

TOST CREEK NEAR ST. IGNATIUS, MONT.

Post Creek rises on the western slope of the Mission Range and 

flows southwestward to Mission Creek. It is the outlet of Lake 

McDonald, and its flow can be equalized throughout the year by 

utilizing the lake for storage.

The gaging station, which was "established September 21, 1906, 

to obtain data for use in connection with irrigation and power projects, is located at the home of Joseph Allard, about 10 miles-north 

of St. Ignatius, Mont.

Two small ditches divert water above the gage to irrigate a few 

acres. The North Fork, the only important tributary, enters 2 or 3 

miles below the gage.

During the flood of June, 1908, a new channel was opened through 

the timber on the right bank. Flow in this channel was first measured November 9, 1908. Computations after June, 1908, have been 

revised to include the flow in this new channel and supersede data as 

published in Water-Supply Paper 252.

The staff-gage datum has remained unchanged. Discharge measurements are made by wading just below the gage.

The current is swift, and the records of flow are but little 'affected 

by ice during the winter months. The channel is permanent, and 

the conditions for obtaining accurate discharge data are good.

NOTE. These discharges, except as noted below, are based on rating curves applicable as follows: Jan. 1 

to Mar. 31,1908, indirect method for shifting channels used. Apr. 1 to June 5, 1908, well defined between 

25 and 380 second-feet. June 26, 1908, to Dec. 31, 1909, includes the flow in new channel and is fairly 

well defined between 24 and 215 second-feet. Discharges June 6 to 25, 1908, estimated; July 20 to 31,1908. 

estimated by hydrograph comparison with the flow at neighboring stations; Jan. 5, 6, May 11 to 14, and 

June 17, 1909, interpolated; Aug. 1 to 25, and Sept. 12 to Nov. 30, 1909, estimated by hydrograph comparison with neighboring stations.

NOTE. Estimates for 1908 have been revised on basis of additional data and supersede those published 

for this station in Water-Supply Paper 252, page 110.

JOCKO RIVER DRAINAGE BASIN. 

DESCRIPTION.

Jocko River rises in the eastern part of the Flathead Indian Reservation and flows in a general northwesterly direction into Flathead 

River near Dixon.

JOCKO RIVER NEAR JOCKO, MONT.

This station, which was established August 20, 1908, is located at 

the highway bridge on the road between Jocko and Ravalli about 

1| miles northwest of the Jocko Agency. Big Knife Creek enters 

Jocko River above the gage, and Finley, Agency, and Valley creeks 

enter below the station. A few small ditches divert water from 

Jocko River between its source and Ravalli, and the waters of its 

tributaries are used to some extent for irrigation near the Jocko 

Agency. Indian ditch, diverted from the East Finley, is the largest 

ditch now in operation. Five thousand acres are to be irrigated hi 

the upper Jocko Valley.

A staff gage is nailed to the middle pier of the downstream side 

of the highway bridge. The gage datum has remained constant.

Measurements are made by wading at low water and from the 

highway bridge in flood season. The channel is not likely to shift in 

ordinary stages.

The stream is being used by the Reclamation Service for irrigation. This river also affords opportunities for power development, 

as it carries a good supply of water at a rapid fall, and in many places 

is bounded by high cliffs.

JOCKO RIVER AT RAVALLI, MONT.

This station, which is located about 400 feet downstream from a 

point opposite the railroad station at Ravalli, Mont., was established 

October 18, 1906, to obtain data for use in connection with irrigation 

and power development.

Several small irrigation ditches divert water above the staff gage, 

but the total diversion probably does not exceed 1 per cent of the 

discharge of the stream.

The current is swift and the flow is but little affected by ice during 

the winter months. The channel shifts during very high water, but 

is permanent at ordinary stages. The conditions for obtaining 

accurate discharge data are good. The gage datum has remained 

unchanged.

At ordinary and low stages measurements are made by wading 

near the gage. During flood stages they can be made from a highway 

bridge three-fourths of a mile above the gage.

BIG KNIFE CREEK NEAR JOCKO, MONT.

Big Knife Creek is a small stream that rises in the mountains and 

flows in a westerly direction until it joins Jocko River about a mile 

north of the Jocko Agency.

The station, which was established August 19, 1908, is located 

near the small highway bridge which spans the creek about 2£ miles 

northeast of Jocko, Mont. The staff gage is located just above the 

bridge. All measurements are made by wading.

There are no ditches diverted from this stream. The creek freezes 

over in cold weather. The staff gage datum has remained unchanged. 

The channel does not shift except in extremely high water.

AGENCY CREEK NEAR JOCKO, MONT.

Agency Creek is a small stream that rises in the Mission Range and 

flows in a westerly direction until it joins Jocko River near Agency.

The stream has a steep grade and a rapid flow. It partially 

freezes over during the colder months. Its flow is controlled by the 

melting snow in the mountains.

The station, which was established August 19, 1908, is located 

about 2 miles east of Jocko, just above the intake of the Matt ditch, 

the largest ditch leaving the stream. Smaller ditches are diverted 

below. A small staff gage is used. All measurements are made by 

wading.

EAST JFINLEY CREEK NEAR JOCKO, MONT.

East Finley, a small creek rising in the Mission Range and fed by 

melting snow in the mountains, unites with the West Fork to form 

Finley Creek.

The station, which was established August 18, 1908, to obtain 

data for irrigation, is 4 miles southeast of Jocko, 4£ miles east of 

Arlee, and is located just above the intake of the Indian ditch. This 

ditch is the only diversion and in low water takes practically the entire 

flow of the stream. The staff gage is permanent and the datum has 

remained unchanged. Measurements are made by wading.

INDIAN DITCH NEAR JOCKO, MONT.

This station, which was established August 18, 1908, is located on 

the ditch just below its intake, 50 feet below the gage on East Finley 

Creek. A staff gage is in the flume and measurements can be made 

there or in the ditch. The data obtained are to determine the amount 

of water now used in the ditch. The ditch is about 4 miles long and 

irrigates land in the vicinty of Jocko Agency. During the irrigating 

season the ditch carries about 6 second-feet.

SPOKANE RIVER DRAINAGE BASIN. 

DESCRIPTION.

Spokane River rises in Coeur d'Alene Lake in western Idaho, flows 

west and northwest and discharges into Columbia River at Fort 

Spokane, Wash. The principal tributaries received between the 

lake and the Columbia are Lattah or Hangman Creek, which enters 

the stream from the south near Spokane, Wash.; Little Spokane 

River, which comes in from the north about 12 miles below Spokane; 

and Chamokane Creek, which is tributary from the north and forms 

the eastern boundary of the Spokane Indian Reservation. Its 

drainage area comprises about 4,000 square miles. Nearly all of it 

is heavily forested and a large area is included in the Coeur d'Alene 

National Forest.

The topography of the country is rugged and broken. The valleys' 

sides are very steep and many of the peaks rise to regions of perpetual snow.

The mean annual rainfall at Spokane is 17 inches, at St. Maries, 

20 inches, and on the summit of the Coeur d'Alene Mountains it is 

probably 50 inches or more. A large portion of the precipitation, 

particularly at the higher altitudes, is in the form of snow whose 

gradual melting helps to feed the streams during the summer season. 

Occasionally the snow banks are melted suddenly by chinook winds, 

and when these winds are accompanied by heavy rainfall the flood 

damage is sometimes great, although its severity is mitigated to a 

large extent by the natural storage in Coeur d'Alene Lake.

The lands bordering Spokane River are for the most part agricultural. Above Spokane the valley is comparatively wide and level 

and is underlain throughout with coarse gravel that affords ample 

ground-water storage from which a liberal supply for irrigation can 

be drawn. A gravity system diverts water from the right bank of 

Spokane River at Post Falls. Below Spokane7 where the river flows

in a comparatively deep canyon, the agricultural lands consist of 

narrow strips along the river banks and are irrigated for the most 

part by pumping from the river. The lands flanking the canyon of 

Spokane River are high and are used extensively for wheat raising. 

The chief products of the region, however, are from its mines.

CcBur d'Alene Lake, which receives the drainage fronrthe western 

slope of the CcBur d'Alene Mountains occupies a wide valley between 

two ranges of mountains. Its upper end is within the Cceur d'Alene 

Indian Reservation. The lands bordering it are for the most part 

low and swampy, and the lake itself is being gradually filled by 

sediment brought in by St. Joseph and Cceur d'Alene rivers, its 

principal tributaries. Undoubtedly, the lake once extended a considerable distance up the valleys of these streams, and for 15 or 20 

miles, above their mouths the bottom lands are subject annually to 

overflow, except where the rivers are artificially confined in their 

channels. Along the immediate banks of the streams the land is 

relatively higher than that nearer the hills. The channels of the 

rivers are comparatively deep and are favorable for navigation. 

The valleys are used more or less for agriculture.

The Spokane affords a large amount of power. At Post Falls, 8 

miles below the outlet of Cceur d'Alene Lake, the Washington Water 

Power Co. has constructed a dam and power plant. The crest of 

this dam is at elevation 2,116.5 feet above sea level and is provided 

with a bear-trap dam 100 feet in length by means of which the water 

can be raised 10 feet above the crest proper. There are also eight 

Tainter gates which, when opened, afford an additional spillway 

length of 159 feet. The company's overflow privileges do not allow 

them to raise the height of water in CcBur d'Alene Lake above an 

elevation of 2,126 feet. During floods, therefore, the Tainter gates 

are opened and the bear-trap dam is lowered in order to afford as 

large capacity of outflow as possible. When the water falls to an 

elevation of 2,126 feet in the lake the bear trap is raised and the 

Tainter gates are manipulated to maintain the water at this point 

as nearly as possible. The waters so stored are released through 

the power houses. The Post Falls plant of the Washington Water 

Power Co. has'a nominal capacity of 15,000 horsepower; the Spokane 

plant, 12,000 horsepower. The Ninemile plant of the Inland 

Empire Railway Co. has a capacity of 10,000 horsepower. (See 

PL IV, A.) At Little Falls the Washington Water Power Co. is 

just completing a plant for a development of 20,000 horsepower. 

Another plant is projected at a favorable point 14 miles below Little 

Falls, and still another at the Narrows at the mouth of the river near 

Fort Spokane. At both of these places plants of 20,000 horsepower 

capacity could be constructed.
116 SURFACE WATER SUPPLY, 1909, PART XII.

CCEUR D'ALENE LAKE AT CCEUR D'ALENE, IDAHO.

A gage was established in this lake February 15, 1905, at Cceur 

d'Alene, Idaho, by the United States Geological Survey. The records 

were suspended on September 30, 1905, by the Survey, but the 

Washington Water Power Co. has maintained gage readings here 

since that time. Since April 26, 1903, the St. Joe Boom Co. has kept 

gage records at their sorting gap at Chatcolet at the mouth of St. 

Joseph River.

The zero of the United States Geological Survey gage is 2,119.75 

feet above sea level and the same datum has been used by the Washington Water Power Co. The St. Joe Boom Co.'s gage is at an 

arbitrary datum. Comparison of records for 1906-7 indicates that 

the zero of this gage is 2,118.80 feet above sea level. On December 

28 and 29, 1909, a comparison of the Washington Water Power Co.'s 

gage and the St. Joe Boom Co.'s gage indicates the zero of latter gage 

to be 2,118.55 feet. Such comparisons are not as reliable as could 

be desired on account of wind effect on the lake and the gradual 

rising and falling of the lake surface. The Washington Water 

Power Co. has used 2,118.7 as the zero of the Boom Co.'s gage, and 

this elevation is probably as nearly correct as can be determined 

without running a very expensive level line over the mountains or 

installing self-registering gages.

All gage heights observed from the St. Joe Boom Co.'s gage from 

April 26, 1903, to February 14, 1905, had been reduced to the datum 

of the United States Geological Survey gage. Add 2,100 feet for 

sea-level elevation. Gage records have been furnished by the St. Joe 

Boom Co. and the Washington Water Power Co.

SPOKANE RIVER AT SPOKANE, WASH.

A record of gage heights of Spokane River has been kept by the 

Washington Water Power Co. at their dam at Spokane, Wash.,1 

since March 22, 1891.

The station was originally established by the United States Geological Survey October 17, 1896, but gage height readings were not 

begun until October 25, 1896. They have been continuous since that 

date. From October 17, 1896, to July 8, 1903, the station was at 

the Oregon Railroad & Navigation Co.'s railway bridge. From July 8, 

1903, to March 30, 1904, it \vas located at the Olive Avenue Bridge.

The gage at the Olive Avenue Bridge was set to read the same as 

the one at the Oregon Railroad & Navigation Co.'s bridge, and, 

although there was a fall of 1.43 feet, the gages did read practically 

the same between 2.85 and 5 feet. On March 30, 1904, a gage was 

installed on the south side of the Mission Street Bridge and a cable 

was installed for making measurements at Martha Street, half a 

mile above the Mission Street Bridge. The gage at Mission Street 

was read from March 30, 1904, to March 1, 1907. On April 17, 1905, 

an auxiliary gage was installed a short distance upstream from the 

cable at Martha Street. During 1906-7 simultaneous readings were 

obtained on the Mission and Martha Street gages in order to determine the relation between the two. 2 Since March 1, 1907, the Martha 

Street gage has been used for daily observations.

At present measurements are made from the cable at Martha 

Street.

1 For full description of this station see the Eighteenth Ann. Kept. U. S. Geol. Survey, pt. 4, 1896, pp. 

359-360. Gage heights from 1891 to 1896, with full notes regarding changes in waste-gate openings and 

flashboards as furnished by the company, were published in Water-Supply Paper U. S. Geol. Survey 

No. 11, pp. 85-88.

s This table was published in Water-Supply Paper U. S. Geol. Survey No. 252, p. 119.
NOKTH PACIFIC COAST. 121

The conditions at the station are favorable for good results. The 

banks are not subject to overflow. The bed of the stream is composed of gravel and changes slightly during freshets, but the flow is 

controlled by a broad riffle above Mission Street. The discharge of 

the river at this point is greatly influenced by the operation of the 

power plant at Post Falls. During the summer water is stored in 

Cosur d'Alene Lake. A dam for this purpose was completed in July, 

1906.

The gage heights for 1891-1896, furnished by the Washington 

Water Power Co., have been revised by applying corrections for 

manipulation of the waste gates and flashboards and are republished 

in the following tables. By means of a table of gage relations, 

determined from simultaneous readings during 1896-1897 for this 

gage and the United States Geological Survey gage at the Oregon 

Railroad & Navigation Co/s bridge and the 1897 rating table,1 a 

rating table has been developed which is applicable for the above 

period. Estimates of discharge for 1891-1896 are published below for 

the first time. The data for 1897 to 1908 have been published in the 

regular reports for those years. (See tables on pp. 15-16.) Though 

many of these data are good, some of them are subject to certain 

revisions based on later measurements. The revision has not yet 

been made.

NOTE. The daily discharges for 1909 are based on a rating curve that is well denned below 2,700 secondfeet, and fairly well defined above this. The rating curve was applied as for open-water conditions for 

the entire year, as the slight ice conditions in January probably caused no appreciable eflect on the flow. 

Discharge under artificial control from Post Palls dam during summer months.

132 SUEFACE WATEE SUPPLY, 1909, PAET XII. 

OKANOGAN RIVER DRAINAGE BASIN. 

DESCRIPTION.

Okanogan River rises in Okanogan Lake, in British Columbia, and 

flows southward, entering Columbia River near Brewster, Wash. 

Its course in Canada lies through a series of narrow lakes. The 

drainage area is comparatively rough and mountainous, and is timbered except along the river. The rainfall is approximately 20 

inches a year.

The principal tributaries in the United States are Similkameen 

and Conconully rivers and Sinlahekin, Antoine, Bonaparte, Johnson, and Salmon creeks. The main stream is navigable from Brewster to Riverside, except during low-water periods, and the tributaries are used largely for irrigation.

SALMON CREEK NEAR OKANOGAN, WASH. 1

This station, which was established May 27, 1903, is located on 

the stage road between Malott and Conconully, 14 miles from Malott 

and 11 miles from Conconully, and is 6 miles above Okanogan, Wash., 

at the mouth of the stream. The waters of this creek are used for 

storage in the development of the Okanogan project of the United 

States Reclamation Service, which has recently been completed. 

(See PI. IV, #.) About 20,000 acres of land have been brought under 

irrigation and are at present open to settlement under the terms of 

the reclamation act.

The vertical staff gage is on the left bank, opposite the house of 

the observer. Discharge measurements are made from a footbridge.

The conditions at the station are favorable for good results. The 

bed of the creek, however, is not stable, and in order to obtain refined 

results frequent discharge measurements should be made each year.

in the northern part of Okanogan County and flows southeastward, 

uniting with Columbia River near Pateros. It is about 60 miles long, 

and its drainage basin, which lies west of the Okanogan Basin and 

east of the basin of Chelan Lake, comprises about 1,700 square miles. 

The most important tributaries of the Methow are its East Fork, 

which joins it near Winthrop, and Twisp River, which enters from 

the west at Twisp.

The country is rough and mountainous and lightly forested. The 

mean annual rainfall ranges from 70 to 80 inches on the summit of 

the Cascades to about 15 inches at the mouth of the river. Irrigation 

is not practiced except on the lands lying contiguous to the streams. 

A project is now under way whereby a large portion of the water will 

be used for the irrigation of bench lands in the vicinity of Brewster. 

The climatic conditions are favorable for intensive agriculture.

METHOW RIVER AT PATEROS, WASH.

This station was first established May 3, 1903, about one-fourth 

mile above the old county bridge at Pateros, Wash., and then moved, 

June 17, 1903, about one-half mile upstream.

The inclined gage at the new location is fastened to two pine trees 

on the left bank and out of the influence of backwater from Columbia 

River. The first two discharge measurements were made from the 

county bridge. This bridge washed out in the summer of 1903 and
NOKTH PACIFIC COAST. 135

subsequent measurements were made from a temporary bridge near by. 

On June 4, 1904, a cable was installed 500 feet above the gage.

No tributaries enter in the immediate vicinity of the station. During the winter months observations are sometimes complicated by ice, 

although the difficulty has not been serious.

The conditions at the station are favorable for good results, and it 

is believed that the records are fairly reliable considering the few 

measurements made.

CHELAN RIVER DRAINAGE BASIN. 

DESCRIPTION.

Chelan River forms the outlet of Lake Chelan in Chelan County, 

Wash. The river, which joins Columbia River at Chelan Falls, 

Wash., is only 4 miles long and in this distance has a fall of 380 

feet, which as yet has not been utilized for power development.

Chelan Lake is a narrow body of water, 48 miles long and about 

1 mile wide, lying at an elevation of 1,080 feet above sea level. It 

is fed by mountain streams which have their sources in the glaciers 

of the Cascade Range. Owing to its great depth and to the mild 

temperature of the region, the lake is open to navigation for the 

whole year. The area contiguous to the lake is exceedingly rugged 

and mountainous and is lightly forested. The mean annual rainfall 

at Chelan is about 13 inches.

CHELAN RIVER AT CHELAN, WASH.

This station was established Novembet 6, 1903, at a highway 

bridge 3,000 feet below the outlet of Chelan Lake, 4 miles northwest 

of Chelan Falls, in the town of Chelan, Wash.

Discharge measurements prior to 1906 were made from the new 

highway bridge half a mile above the gage and above a dam at the 

outlet of the lake. This dam partially controls the flow of the river. 

Since 1906 discharge measurements have been made at the lower 

bridge where the staff gage is located. The gage datum has remained 

unchanged. High-water measurements can best be made at the 

upper bridge.

The data obtained here are valuable for use in future water-power 

developments.

WENATCHEE RIVER DRAINAGE BASIN. 

DESCRIPTION.

Wenatchee River rises in Cady Pass, at an elevation of 4,500 feet, 

flows southeastward, passing through Wenatchee Lake at an elevation of 1,870 feet, and empties into Columbia River at the town of 

Wenatchee, Wash. With its tributaries it drains a stretch of the 

eastern slope of the Cascade Mountains about 40 miles long and the 

territory north of the Yakima River drainage basin, from which it is 

separated by the Wenatchee Mountains.

The river has a number of tributaries, among which may be mentioned North Fork River, which flows into Wenatchee Lake near its 

head, and Chiwawa, Nason, Chumstick, Icicle, Peshastin, and Mission creeks. The upper part of the drainage area is heavily forested, 

but the extreme lower part consists of timberless hills and ridges, in 

most places covered with sagebrush.

The mean annual precipitation at Wenatchee is 16 inches, a large 

part of it being in the form of snow. During portions of the winter 

the streams are icebound.

The data obtained are used in connection with the development of 

irrigation and water power. The Great Northern Railway has recently built a hydroelectric plant at Leavenworth, where about 7,000 

horsepower is developed to operate trains through the Cascade tunnel.

WENATCHEE RIVER AT SHERMAN SPUR, NEAR DRYDEN, WASH.

This station was established April 27, 1909, by the Valley Power 

Co. at their power plant at Sherman Spur, a station on the Great 

Northern Railway, near Dryden post office and about 6 miles
140 SURFACE WATER SUPPLY, 1909, PART XII.

above Cashmere, Wash. It is about 500 feet below the Great 

Northern Kailway bridge, and about 1 mile below the head gate of 

High-Line canal.

The gage is a vertical staff fastened to the cribwork opposite the 

power house, and is practically in the tailrace of the power plant. 

No equipment for measuring discharge has been installed.

Gage heights have been furnished by the Valley Power Co.

1909.

WENATCHEE RIVER, AT CASHMERE, WASH.

This station was originally established July 26, 1904, at the highway bridge in Cashmere, Wash., 1J miles below the mouth of Mission 

Creek and 8 miles above the mouth of the river. The bridge was 

rebuilt during the summer of 1907 and the staff gage removed, readings being taken from the temporary gages set by the observer. On 

September 28, 1908, the staff gage was replaced on the bridge at the 

same datum and the gage heights for the intervening period reduced 

to this datum. These gage heights, however, are liable to considerable error.
NORTH PACIFIC COAST. 141

Gage heights were resumed June 20, 1909, and continued until 

October 12. On October 13, 1909, the station was moved 1 mile 

above its former location to a new highway bridge, called the upper 

bridge, on the main road from Cashmere to Leavenworth, where 

conditions for gaging are much better. A chain gage was installed on 

the bridge. Discharge measurements are made from the bridge. 

Gage heights for 1907 and 1908 were published in Water-Supply 

Paper 252, page 132. Daily and monthly estimates of discharge for 

1904 to 1906 have been revised on the basis of later measurements 

and supersede those published in Water-Supply Papers 178, page 42, 

and 211, page 40.

NOTE. The'daily discharges for July 27,1904, to Oct. 12,1909, are based on a fairly well-defined rating curve.

Discharges interpolated for missing periods as follows:

Jan. 2 to 5, Sept. 29 to Oct. 19, Oct. 31 to Nov. 17, and Nov. 30, 1907, Mar. 17 to Apr. 6, 1908.

Water above the gage June 11 to 15, 1908, and discharge estimated as 18,000 second-feet per day.

Discharge estimated Aug. 29 to 31, 1908.

The daily discharges Apr. 26 to June 19,1909, were obtained from the above rating curve by the aid of a 

gage height relation between the gage at the lower bridge and the records at Sherman Spur.

The daily discharges Oct. 13 to Dec. 31,1909, were obtained from a rating curve well defined between 1,000 

and 3,600 second-feet. Discharges Oct. 14 to 16,1909, interpolated.

CRAB CHEEK DRAINAGE BASIN. 

DESCRIPTION.

The streams of the large area of the Columbia Plains embraced in 

the great sweep of the river bounded on the north and west by the 

Columbia, on the south by Snake River, and on the east by the one 

hundred and eighteenth meridian, are insignificant. The only one 

that maintains a perennial flow along the greater portion of its 

channel is Crab Creek, which rises in the vicinity of Davenport, 

Wash., at an elevation of about 2,500 feet. The real channel of Crab 

Creek parallels the Great Northern Railway as far as Adrian. It 

then turns abruptly southward, flows through the easterly tier of 

sections in T. 21 and 22 N., R. 27 E., to about section 12 of T. 21, 

thence diagonally southeastward in a fairly straight course to the 

head of Parker Horn of Moses Lake. This portion of the stream 

may be designated as upper Crab Creek. Along the greater part of 

this stretch, above Wilson Creek, the surface flow is perennial, though 

the channel is at times dry from an unknown distance above Odessa 

to a point about 3 miles below, where the stream emerges from the 

gravels in considerable volume. The water sinks again below Wilson Creek, except for a few weeks during the spring high water. 

About 15 miles below the lake the stream again takes a westerly 

direction, flowing in a broad-bottomed, steep-walled canyon. At 

some point near the middle of this lower course Crab Creek sinks 

finally, and it delivers no surface water to the Columbia at the 

mouth of its canyon, except at times of freshets. This section of 

the stream below Moses Lake may be designated lower Crab Creek.

Crab Creek has only a few branches that contribute to its surface 

flow throughout the year and a few more that flow during the rainy
NOBTH PACIFIC COAST. 147

season, but it has a great number of deep tributary canyons, many 

of them scores of miles in length, which are dry except at periods of 

unusually heavy rainfall. These canyons, dry or containing only 

small streams disproportionate to their size, are known as coulees. 

They have all the topographic characters of stream-carved valleys, 

but evidently could not have been formed by stream erosion under 

present conditions. Their origin must be referred to a prehistoric 

period in which the region had an abundant rainfall and was well 

watered by surface streams. These branching systems of dry canyons represent ancient river systems.

The most important of the branches of the ancient Crab Creek system, except Grand Coulee, is Lind Coulee, in which the Northern 

Pacific Railway runs from Providence to Ritzville.

Providence Coulee, in which Hatton, Scott, and Connell are situated, is now devoid of flowing water, though it once formed the trunk 

of a river system almost as large as that for which Crab Creek is the 

master stream.

Of all the abandoned canyons of the Columbia Plains, however, the 

greatest and most remarkable is Grand Coulee. Not only does it 

possess many features of scenic grandeur, but its geologic history is 

of the highest interest. This great chasm was carved by Columbia 

River at a time when its profound gorge was dammed by a great ice 

lobe that came down the valley of the Okanogan and pushed southward some 30 miles across the plateau south of the master stream. 

The waters of the Columbia, deflected by the great glacier, flowed 

along its eastern face, and continuing southward in what is now the 

bed of Crab Creek regained their proper channel just above Sentinel 

Bluffs.

Lakes, generally small and shallow and invariably situated in 

coulees, are numerous hi the northern portion of the region. Their 

basins were formed by the erosion of former streams or dammed by 

wind-blown materials, and they are therefore usually elongated in 

form and separated by stretches of dry or meadowy land. The most 

important series of lakes in this region is that which lies in the bottom 

of the Grand Coulee and which includes Moses Lake, the largest sheet 

of water in the Columbia Plains.

Most of the lakes in this arid region have no outlets; others overflow only in the rainy season; as a consequence the small amounts of 

salts contained hi all surface waters are concentrated hi the lake 

basins by evaporation, and most of the lakes are more or less alkaline, 

Moses Lake containing about 0.32 gram of total solids per liter of 

water.*

i Ann. Kept. Geol. Survey Washington, vol. 1,1901, p. 294.
148 SUBFACE WATEB SUPPLY, 1909, PAET XII.

The lakes in the lower section of the Grand Coulee are successively 

higher from south to north, and the northern lakes occasionally overflow to the south at seasons of high water. It follows that while the 

water of the northernmost of these lakes is comparatively fresh and 

palatable, the waters of the others become successively more alkaline to 

the south, those of Soap Lake, the most southerly, being extremely 

alkaline.

The annual rainfall in this area is from 10 to 20 inches, most of 

which falls during the winter months. On the higher lands, which 

receive more rainfall than the valley lands, great quantities of wheat 

are grown; on the lower lands successful agriculture is not possible 

without irrigation. Some development by pumping from Moses Lake 

and from wells has proved fairly successful. About 1,000 acres of 

land between Adrian and Ephrata are irrigated by a gravity system 

that takes water from Upper Crab Creek.

UPPER CRAB CREEK NEAR EPHRATA, WASH.

This station, which was established June 21, 1909, is located at 

Drumheller's ranch, 8 miles southeast of Ephrata, in the SE. I sec. 5, 

T. 20 N., K. 27 E. It is maintained in cooperation with Ham, Yearsley & Ryrie, of Spokane. The data obtained are of value in connection with the development of irrigation by storage in Moses Lake.

The gage is a vertical staff on the right bank of the stream at a 

private bridge 500 feet south of Drumheller's house. Measurements 

are made from the bridge. The bed of the stream is of hard clay 

and not liable to change.

The waters in this stream are supplied entirely from copious springs 

about 6 miles above the station.

150 SURFACE WATEE SUPPLY, 1909, PAET XII.

MOSES LAKE AT MOSES LAKE, WASH.

The lake gage was established in the Parker Horn of Moses Lake 

June 23, 1909. The gage is located 1 mile west of Moses Lake post 

office, on the east shore of Moses Lake near the center of sec. 28, 

T. 19N.,K. 28 E. The gage was established in connection with the 

evaporation station at this point.

Heights obtained here are used in the study of the available 

storage in Moses Lake, the waters of which will be used to irrigate 

lands on the south side of Frenchman Hill.

The evaporation pan is of galvanized iron, 3 feet square and 2 feet 

deep, inclosed by a boom of logs. In the center of- the pan is a needle 

point to which the water is adjusted at-the time of observations. The 

observer is supplied with a cup which holds sufficient water to increase 

the depth in the pan one-tenth of an inch. In this manner the number of cupfuls added at each observation is readily reduced to inches 

of evaporation. There is also a rain gage at Moses Lake post office.

Daily gage height, in feet, of Moses Lake at Moses Lake, Wash., for 1909.

LOWER CRAB CREEK NEAR WARDEN, WASH.

This station, which was established June 23, 1909, is located on 

the McManaman ranch, 12 miles west of Warden, in the SW. | 

sec. 24, T. 17 N., R. 28 E. The data obtained here are used in connection with the proposed project for the storage of water in Moses 

Lake for the irrigation of lands south of Frenchman Hill.

The gage is a vertical staff driven in the bed of the stream on the 

left bank. Measurements are made by wading. The banks of the 

stream are low and subject to overflow. The bed is composed of 

shifting sand. During the summer months the water is supplied by 

seepage from Moses Lake and from several springs in the vicinity. 

The largest spring, that on the lower Drumheller ranch, probably 

discharges 15 to 20 second-feet.

YAKIMA RIVER DRAINAGE BASIN. 

DESCRIPTION.

Yakima River rises in Keechelus Lake, in the northwestern part 

of Kittitas County, and flows southeastward for about 150 miles to 

its junction with the Columbia, 8 miles northwest of Pasco and 4 

miles above the mouth of Snake Eiver. Its drainage area, comprising 5,270 square miles, extends southward from the Wenatchee 

Mountains and includes a stretch of nearly 100 miles along the eastern slope of the Cascade Eange. It has many tributaries, the most 

important coming from the west, as is shown by the following table:
NORTH PACIFIC COAST. 153

Principal tributaries of Yakima River.

From the north, and east: 

Kachess Biver (Kachess Lake). 

Clealum River (Clealum Lake), 

Teanaway Creek. 

Swauk Creek. 

Wilson Creek. 

Cherry Creek 

Selah Creek.

From the south and west:

Big Creek.

Taneum Creek.

Manastash Creek.

Wenas Creek.

Naches River (draining about 50 miles of 

Cascade Range).

Tieton River.

Oowiche Creek.

Atanum Creek (forming northern boundary of Yakima Indian Reservation).

Toppenish Creek (draining Yakima Indian Reservation).

Satus Creek.

The country at the headwaters of these streams is densely forested 

and mountainous. The general elevation of the summit of that 

portion of the Cascade Mountains drained by them is 5,500 feet 

above sea level. Keechelus Lake is 2,458 feet above sea level, 

Kachess Lake 2,230, Clealum Lake 2,130, Ellensburg 1,545, North 

Yakima 1,090, and Kiona 515 feet.

The agricultural lands of this basin lie in four distinct valleys. 

The upper, beginning just below the mouth of Swauk Creek and 

known as the Kittitas Valley, is somewhat oval in shape, about 30 

miles long and 16 miles wide. Ellensburg is its chief city. Below 

Kittitas Valley the river flows in a narrow canyon, from which it 

emerges into Selah Valley. From Selah Valley it passes through 

a narrow gap into Yakima and Moxee valleys. Below Moxee Valley the river has cut its way through the Atanum and Rattlesnake 

ridges, forming a short narrow canyon, known as Union Gap. Below 

Union Gap the river flows to its mouth through a wide valley, 

unbroken except for the Toppenish Ridge, which lies south of the 

river, approximately at right angles to its course.

The mean annual rainfall at Clealum is 28 inches, at Ellensburg 

10 inches, at North Yakima 9 inches, and at Sunnyside 7 inches. 

The greater part of the precipitation occurs in the winter as snow. 

The snowfall near the summit of the Cascade Range frequently 

aggregates 25 or 30 feet in one season.

Irrigation has been practiced in this valley for many years, and 

ditches of all sizes from the small ditch watering a few acres on 

the banks of the creeks to large canals that extend for 60 miles and 

cover 40,000 or 50,000 acres of land have been in successful operation for a number of years. The products cover the entire range of 

irrigated agriculture, from hay and grain in the upper portion of the 

valley to the fancy fruits raised throughout the lower portions of
154 SURFACE. WATEE SUPPLY, 1909, PART XII.

the basin. Irrigated orchards in the vicinity of North Yakima have 

attained a value of $1,000 to $3,000 an acre.

The United States Reclamation Service has undertaken the general 

development of this valley. The principal storage reservoirs are 

Keechelus, Kachess, Clealum, and Bumping lakes, and at McAUister Meadows on Tieton River. The development of the projects 

will be made in several units. The first was started by the purchase of the Sunnyside canal, which diverts water from Yakima 

River below Union Gap. The second unit is the Tieton project, 

which diverts water from Tieton River for the benefit of land to the 

west of North Yakima. As Tieton Rvier is the principal tributary 

of the Naches, whose natural flow has been entirely appropriated 

for irrigation through private enterprises, the water to be taken 

from the Tieton will be replaced by the release of water from the 

Bumping Lake Reservoir. Other units are the Wapato project, 

which contemplates the enlargement and extension of two canals 

built by the United States Indian Office and the development of 

small storage reservoirs on the headwaters of Toppenish Creek and 

Kittitas unit for the irrigation of lands in Kittitas Valley.

The intensive agriculture of this valley has rendered necessary 

the development of water powers. Several water-power plants are 

in successful operation, the largest being the plant of the Wapatox 

Co. Water is taken from Naches River in a long canal and used 

both for water power and irrigation.

Records of stream flow have been maintained in this valley since 

1893. The year 1905 was the driest year since records have been 

obtained; 1903 was a wet year.

KEECHELUS LAKE NEAE MARTIN, WASH.

A gage was established in Keechelus Lake January 12, 1906. It 

is just above the outlet of the lake, 4 miles northwest of Martin, 

Wash., on the State road over Snoqualmie Pass.

The gage as originally established was 300 feet from the outlet of 

the lake at an arbitrary datum. When the dam at the outlet was 

completed in the winter of 1906-7, the gage was moved, and now 

indicates the height above the sill of the outlet tunnels in the dam. 

All records have been corrected to this latter datum, which is 2,457 

feet above sea level. (See PL V.)

NOTE. This table has been used to determine the amount of water stored in or drawn from the lake and 

in connection with the records on Yakima River near Martin to compute the inflow into the lake. .

This table differs slightly from that published in Water-Supply Paper 252. It is the same as is now used 

by the United States Reclamation Service.

YAKIMA RIVER NEAR MARTIN, WASH.

This station, which was established October 18, 1903, is located 

at the outlet of Keechelus Lake, 4 miles northwest of Martin station, 

on the Northern Pacific Railway.

The data are used by the United States Reclamation Service in 

their general studies for the reclamation of lands in the Yakima 

River valley. Keechelus Lake is at present used as a storage reservoir. A temporary timber dam has been constructed, which will be 

replaced by a permanent dam high enough to fully develop the 

storage capacity of this area.
156 SURFACE WATER SUPPLY, 1909, PART xn.

On November 14, 1903, the staff gage was destroyed and records 

were discontinued until January 28, 1904, when a new vertical staff 

was installed 75 feet above the old location at a new datum, 2,448.76 

feet above sea level. The datum of this gage has remained unchanged. All gage heights in 1903 were reduced to the datum of the 

new gage. The new gage is about 1,000 feet below the outlet of the 

lake and about 800 feet below the dam. Discharge measurements 

are made from a cable at the gage.

The conditions at the station are favorable for obtaining good 

results. During the winter months, although the lake freezes, the 

flow at the station is under open-channel conditions on account of 

the rapid velocities which obtain.

158 SURFACE WATER SUPPLY, 1909, PART XII.

YAKIMA RIVER AT CLEALUM, WASH.

The station, which is located at the highway bridge just above the 

town of Clealum, Wash., 6 miles above the mouth of Teanaway 

Eiver and 3 miles below the mouth of Clealum River, was established 

August 26, 1906, to obtain data to be used in determining the most 

economic method of operating the storage reservoirs contemplated 

and under construction on the headwaters by the United. States 

Reclamation Service. The records also show the combined flow of 

the three rivers forming the headwaters of Yakima River.

A chain gage is installed on the highway bridge, from which discharge measurements are made. The flood of November, 1906; 

partly destroyed the bridge and the gage equipment. The datum 

was maintained, although the channel conditions were so altered that 

another rating was required. Since that date the conditions have 

been more favorable for good results than they were before, and the 

data are reliable. On November 7, 1909, it was found that the gage 

datum had lowered 0.27 foot, by the settling of the bridge. No corrections were made to the gage heights, as it was impossible to determine when the settling occurred. Sufficient measurements were 

made in 1909 to define a rating curve for the changed datum.

Ice affects the gage heights for a short period during the winter 

months. At such times, and where other means fail, the data are 

usually supplied by interpolation.

YAKIMA EIVER AT UMTANUM, WASH.

The station which was established August 25, 1906, at Umtanum, 

Wash., in the canyon of Yakima River between the Kittitas and 

Selah valleys, 1 mile above the mouth of Umtanum Creek, affords 

data that are valuable in the general scheme of reclamation undertaken by the United States Reclamation Service. The records indicate the amount of water available from Yakima River for the Selah 

and Moxee valleys and show also the amount passing the Kittitas 

Valley after all seepage waters from irrigation are returned to the 

river. The records are also extensively used during the irrigating 

season at this point in conjunction with those at Clealum and Union 

Gap in studying the most economic method of operating storage 

reservoirs which are contemplated and under construction for the irrigation of the valley.

The vertical staff gage is in four sections, located as follows: The 

low-water section is in the right bank back of the section house; 

section 2 is a staff 25 feet downstream; section 3 is 50 feet back of the 

low-water section; and the high-water section is 20 feet back of the 

third section. Discharge measurements are made by means of a cable 

equipment 75 feet upstream from the low-water section.

The conditions are favorable for good results and the data obtained 

are reliable. A riffle control is located about 300 feet below the gaging 

section, and the gage height is a good index of the flow. Gage heights 

are somewhat affected during the winter months by ice, but, as the 

ice periods are short and do not occur at critical stages, the errors 

due to this cause are not great.

YAKIMA RIVER NEAR YAKIMA, WASH.

This station is located at Union Gap, a short canyon through 

Atanum Ridge near Yakima, Wash. It was established August 14, 

1893, but discharge can be computed only from August 19, 1895, as 

the records are fragmentary prior to that date. This station was 

discontinued December 31, 1909, in favor of the Wapato station.

The station is of importance to the determination of the discharge 

of the river, as it is located at a critical point unaffected by the diversion of water for the large irrigated areas above and below. It is just
NORTH PACIFIC COAST. 163

below the mouth of Atanum Creek and above the head gate of the 

New Reservation canal; there is only a short stretch of river in which 

the station can be located, the distance between these points being 

less than half a mile. The discharge at this point is approximately 

equal to the sum of the discharge of Yakima Kiver at Umtanum, 

Naches River at North Yakima, Atanum Creek, the return waters in 

the Selah and Moxee valleys, and the waste from the North Yakima 

power canal. The records show also the amount of water available 

for the Sunnyside and Old and New Reservation canals, all of which 

have their intakes a short distance below.

The records were fairly reliable until the flood of November 15, 

1906, which so deepened the channel at the measuring section that the 

current is very sluggish at low water. The flood also deepened a 

small channel near the left bank, which previously did not carry water 

except at flood periods, but which now carries a considerable portion 

of the flow even at medium stages. On account of these changes it 

has been impossible since the above date to obtain reliable estimates 

of discharge. The record of gage heights for 1909 is not published as 

the gage heights are not a true index of the discharge. The monthly 

discharge may be computed, however, by adding the flow of the three 

canals to the flow over the Sunnyside dam.

The datum of the gage has not been changed since the station was 

established, but a number of rating curves have been used on account 

of changing conditions.

The river frequently freezes during the winter months, and ice 

jams are common in the vicinity of the station.

This station, which was established April 25, 1908, is located just 

below the head gate of the Sunnyside canal, which is owned and operated by the United States Reclamation Service.

The flow at this point is controlled by a concrete diversion dam 500 

feet long, of ogee cross section 7 feet high. A sluiceway in the dam 

is closed by means of flashboards during the irrigating season. There 

is also a fish ladder near the sluiceway through which a small quantity 

of water flows all the time.

Discharge measurements are made from a cable which spans the 

river 1,000 feet below the dam. Two gages were read in 1909 a hook 

gage and a chain gage. The hook gage is in the fore bay above the controlling gates for Sunnyside _canal and indicates head of water flowing over the dam. An auxiliary gage installed above the dam was 

used when the hook gage was frozen up, these readings being corrected 

to the hook gage datum. The chain gage is located at the cable section at an arbitrary datum. The relation between the gages has been
164 SURFACE WATER SUPPLY, 1909, PART XII.

determined and all gage heights for 1909 are referred to the datum of 

the chain gage. Owing to variable effect of drift logs on the crest of 

the dam the hook gage heights are not a good index of discharge. 

Those obtained from the chain gage have therefore been used in determining discharge. The records are reliable.

The results obtained at this station, when added to the diversions 

measured in the Sunnyside canal, the Old and New Reservation 

canals are comparable with records formerly obtained at Union Gap.

YAKIMA RIVER AT KIONA, WASH.

This station was established August 20, 1895, at the highway 

bridge about 1,800 feet northwest of the Northern Pacific Railway 

station. No tributaries enter in the vicinity of this station.

The chief value of the data lies in the fact that they cover a long 

period and are accurate. Much water is diverted from the river, 

both below and above the station. At the medium and high stages 

the total amount of diverted water is but a small per cent of the 

flow of the river, but at low stages this condition is reversed, and 

the water passing Kiona consists in large part of return water from 

irrigation. The data obtained here are, however, of value as indicating the flow at Prosser, which, on account of certain water rights, 

becomes of considerable importance. Between Prosser and Kiona, a 

distance of 14 miles, there is only one diversion of consequence, the 

Kiona canal and one contribution to the stream, the Prosser wasteway at the end of the Sunnyside canal.

The flow at the gaging station is controlled by a riffle about 1,000 

feet below the bridge, and this control has made the development of 

a permanent rating curve possible. The chain gage now used was 

installed May 8, 1906, on the bridge from which discharge measurements are made, to replace the old wire gage and staff gages formerly 

used. All gage heights have been corrected to a uniform datum. 

During the winter months a small amount of ice is apt to form in 

the vicinity of the station, but only in exceptional seasons does this 

ice interfere with the determination of flow.

YAKIMA RIVER NEAR RICHLAND, WASH.

This station, which is located below all diversions, is maintained 

during the later part of irrigating seasons only to determine the 

amount of water flowing from the Yakima into Columbia River during the low-water period.

The station was originally established at Richland Ferry, Wash., 

8 miles above Kennewick and 2^ miles above the mouth of the river. 

It was moved during 1908 to a highway bridge on the road from 

Richland to Kennewick, half a mile abo~,e the mouth of the river, 

where more favorable measuring conditions existed.
NORTH PACIFIC COAST. 169

The gage used in 1906 was located 500 feet below the ferry. On 

August 13, 1907, a staff gage was installed on an old bridge pier at 

the ferry. The staff gage which was set August 28, 1908, at the highway bridge at a different datum was not found in 1909; consequently 

a new staff was fastened to a pile on the left bank underneath the 

bridge. No relation has yet been determined between the 1908 and 

1909 gages; consequently estimates for 1908 are withheld.

Discharge measurements at the ferry location were made by wading. Measurements at the bridge location are either made from the 

bridge or by wading. The bed of the stream is of gravel and cobblestones and the flow is controlled by a riffle 200 feet below the gage.

CABIN CREEK NEAR EASTON, WASH.

This station was established May 12, 1909, at the Northern Pacific 

Railway bridge one-half mile above the mouth of the stream 2f 

miles west of Easton, Wash. The data are valuable in the general 

study of the Yakima River system to determine the amount of water 

contributed to Yakima River by Cabin Creek and run-off factors that 

can be applied to similar areas.

The gage is a vertical staff fixed to a piling on the right bank underneath the railroad bridge. Measurements are made from the bridge 

or by wading at low stages. There is an east channel whose waters 

do not pass the gage but this is measured and included in the discharge. The east channel is carried under the railroad embankment in a 42-inch iron pipe. The water is confined at all stages by 

the railroad embankment.

The bed of the stream is of gravel and subject to change during 

high stages. From a tributary of Cabin Creek above the station a 

6-inch wooden pipe diverts water for locomotive use at Easton.

Discharge measurements of Cabin Creek near Easton, Wash., in 1909.

NOTE. This4able has been used in determining the amount of water stored in or drawn from the lake, 

and in connection with the records on Kachess River, to compute the inflow into the lake. This table 

differs slightly from that published in Water-Supply Paper 252. It is, however, the same as used by the 

United States Reclamation Service.

KACHESS RIVER NEAR EASTON, WASH.

This station was established October 14, 1903. It is located half a 

mile below the outlet of Kachess Lake and 2 miles northwest of 

Easton. The river receives no important tributaries.

The records determine the amount of water available for storage 

in Kachess Lake, which forms one of the principal reservoirs under 

consideration by the United States Reclamation Service.

The flow is under artificial control, the lake being used for storage 

by the Cascade Canal Co. prior to its acquisition by the United States 

Reclamation Service.

The channel is open throughout the year at this point. The current is swift and ice does not form. The channel conditions at the 

station are not favorable for a high degree of accuracy. The bed is 

composed of gravel and cobblestones and at low stages it is difficult 

to measure depths accurately.

The datum of the inclined staff gage, which is 2,178.41 feet above 

sea level, has not been altered since it was established, and except for 

slight modifications at the low stages a single discharge curve was 

used up to and including 1908. High-water measurements in 1909 

indicated that the high-water portion of the curve gave too large 

discharges, so it has been modified somewhat for 1909 to better 

equalize these later measurements. Discharge measurements are 

made from a cable equipment at the gage.

BIG CREEK NEAR CLEALUM, WASH.

This station, which is located 10 miles west of Clealum, Wash., 

about 4 miles east of Easton, Wash., 1 mile above the highway 

crossing of Big Creek and 50 feet above the head of the Diener ditch, 

the uppermost diversion from this stream, was established May 12, 

1909, to determine the amount of water contributed by Big Creek 

to Yakima River. It was also expected that certain run-off factors 

would be secured that would be applicable on Little Creek, the next 

tributary upstream from Big Creek, but owing to poor records after 

June 9, caused by ditch diversion, the purpose has not yet been 

satisfactorily accomplished.

The gage is a vertical staff fixed to the root of a large tree on the 

right bank. Measurements are made by wading at the riffle 30 

feet below the gage. The banks of the stream are heavily wooded 

and subject to overflow in high stages. The bed of the stream is of 

gravel and sand but the flow is controlled by the riffle.

Observations at this station were suspended September 1, 1909, 

for lack of an observer.

Gage Discharge.

NOTE. The gage observer reported the water as above the gage on June 1 and 2. The above daily discharges were obtained from a fairly well-defined rating curve.

CLEALUM LAKE NEAR ROSLYN, WASH.

Observations of heights of Clealum Lake were begun January 25, 

1906.

The first gage was used until March 31, 1906, when it was destroyed 

by waves. The gage was not referred to a bench mark and the datum 

is lost for that period. The gage heights reported are therefore not 

comparable with subsequent records. Gage No. 2 was installed May 

4, 1906. It is located above the outlet of the lake. The zero of the 

gage is at an elevation of 2,122.30 feet above sea level, United States 

Geological Survey datum. During the winter of 1907-8 a temporary crib dam was constructed 200 feet below the outlet of the lake.

On June 17, 1907, gage No. 3 was fixed to the abutment of this 

dam. The zero of this gage coincides with the top of the sill of the 

outlet tunnels in the dam at an elevation of 2,122.75 feet above sea 

level, United States Geological Survey datum.

Between the outlet of the lake and the dam there is some fall to the 

water surface when the lake stage is below 6 feet, which increases as 

the stage decreases. Prior to March 15, 1908, while the dam was 

under construction, the heights observed on gage No. 3 are not comparable with those formerly obtained on gage No. 2. Since the latter 

date the water has been maintained at a sufficient height to obliterate 

the fall between the two gages. During 1908 a correction of 0.45 

foot was added to heights observed on gage No. 3 to make them 

comparable with those on No. 2, but for 1909 this correction has not 

been made. To render the 1908 records from gage No. 3 comparable
NORTH PACIFIC COAST. 177

with those of 1909 and subsequent years, 0.45 foot should be subtracted from them.

Gage No. 5, installed during 1909, is above the outlet of the lake 

and will not be affected by the fall between the outlet and the dam 

at low stages.

When the lake surface is drawn down sufficiently to develop an 

appreciable current between the lake and the dam, gage No. 5 is 

read; at other times gage No. 3, which is not affected by wave action 

on the lake, is read; gage No. 4 is an auxiliary gage at the dam, 

reading from the same datum as gages Nos. 3 and 5. It is in a stilling 

box in order to indicate the heights with a greater degree of accuracy.

NOTE. This table has been used to determine the amount of water in, or drawn from, the lake, and in 

connection with the records on Clealum River, to compute the inflow into the lake. This table differs

States'Reclamation Service.

84547° WSP 272 11 12
178 SURFACE WATER SUPPLY, 1909, PART XII.

CLEALUM RIVER NEAR ROSLYN, WASH.

This station was established October 10, 1903, to obtain data for 

use in connection with the development of irrigation in the Yakima 

Valley. It is located below the outlet of Clealum Lake, which is to 

be utilized for storage by the United States Reclamation Service.

The inclined staff gage is 1,000 feet below the outlet of the lake, 

about 2^ miles northwest of Roslyn, Wash. It is about 500 feet 

above the cable from which discharge measurements are made.

The conditions at the station are favorable for good results and a 

permanent rating curve has been developed. There was a little dead 

water at low stages, but this difficulty has been removed by relocation of the cable on August 20, 1908, about 500 feet below the former 

site. The datum of the gage has remained constant since the station 

was established. Ice does not interfere with the determination of 

flow during the winter months.

During the winter of 1907 the Reclamation Service completed a 

temporary timber dam for storage. The outflow of the lake is therefore under artificial control.

Before the dam was constructed the lake was used for storage by the 

Cascade Lumber Co., and the flow during the summer months was 

therefore partially under control, although the dam was of temporary 

construction and was replaced each season.

TE AN A WAY RIVEE NEAR CLEALUM, WASH.

This station, which is located at the lower Teanaway highway 

bridge 4£ miles southeast of Clealum, Wash., about half a mile above 

the mouth' and below all diversions for irrigation, was established 

April 2, 1909, to determine the amount of water contributed to 

Yakima River from the Teanaway drainage area.

A number of important ditches take water above the station for 

irrigation, and it was impossible to select a site above them. As 

the stream is used extensively for floating logs during the spring 

months the estimates are subject to errors from the unknown effects 

of backwater caused by logs in the channel. Some unusual fluctuations in the discharge are also caused by water for log driving released 

daily from the splash dams on the forks of the stream 20 miles above 

the station.

The chain gage is fixed to the downstream side of the bridge from 

which measurements are made. The right bank is high and of 

cemented gravel; the left bank is low and wooded and subject to 

overflow during high stages. The bed of the stream is of hard clay 

and gravel and is not likely to change.

SWAUK CREEK NEAR CLEALUM, WASH.

This station, which is located 1J miles above the mouth of Swauk 

Creek, in a narrow canyon on the ranch of B. F. Boice, 12 miles 

southeast of Clealum, was established April 3, 1909, to determine 

the amount of water contributed to Yakima River by this drainage 

area. The canyon of the stream is comparatively narrow and a 

large part of the water diverted for irrigation is taken out by small 

ditches and is returned to the stream above the station. One 

high-line ditch diverts water to lands in the vicinity of Ellensburg, 

thus taking them out of this drainage area altogether.

The gage is a vertical staff fixed to a stump on the right bank 500 

feet below the farmhouse. The banks of the stream are comparatively high and will not overflow except during extreme flood. 

The bed of the stream is of sand and gravel and liable to change 

during floods.

TANEUM CEEEK NEAR THORP, WASH.

This station, which is located 6£ miles above Thorp, 150 feet below 

the logging bridge on the ranch of G. W. De Shazer, was established 

April 4, 1909, to determine the amount of water contributed by this 

drainage area to Yakima R.iver, but on account of the many diversions it was necessary to locate the station above them. The highest 

ditch of importance is Bruton's which heads one-fourth mile below 

the station.

The gage is a vertical staff fixed to an 8-inch cottonwood tree on 

the left bank. Measurements are made by wading in the vicinity 

of the station. The banks of the stream are low, covered with brush, 

and subject to overflow. The bed of the stream is of sand and gravel 

and is liable to change at medium and high stages.

MANASTASH CREEK NEAR ELLENSBURG, WASH.

This station, which was established April 5, 1909, to determine 

the amount of water contributed by the Manastash Creek basin to 

Yakima River, is located a short distance above the mouth of the 

canyon, at a private bridge on the ranch of A. L. Sackett and 8| 

miles west of Ellensburg, Wash.

Below the canyon the creek spreads in a number of channels and 

its water is diverted at many points for irrigation. The amount 

measured at the station, which is at the only suitable point where all 

the waters are confined in one channel, is considerably reduced by 

evaporation before the creek reaches Yakima River, into which it 

finally flows through several channels.

The gage is a vertical staff spiked to a balm tree on the left bank 35 

feet below the bridge. Measurements are made from a foot log below th£»gage or by wading. The banks of the stream are free from 

vegetation and will overflow in extreme high water. The bed is of 

gravel and fairly permanent.

WENAS CREEK NEAR SELAH, WASH.

This station, which was established March 30, 1909, to determine 

the amount of water contributed by the Wenas Creek basin to Yakima 

River, is located about one-half mile above the mouth of the creek 

in the SE. I sec. 18, T. 19 N., R. 14 E.

This station is below all diversions for irrigation and just above a 

rocky gorge through which the creek flows to its junction with 

Yakima River.

The gage is a vertical staff on the left bank 200 feet below the ford 

on Walter Hustead's ranch. Measurements are made by wading or 

from a foot plank 100 feet above the ford. The banks of the stream 

are covered with brush and will overflow in extreme high water.

NACHES RIVER DRAINAGE BASIN. 

DESCRIPTION.

Naches River rises in the western part of Kittitas County, Wash., 

and flows southeastward into the Yakima above the town of North 

Yakima. It is about 50 miles long, and receives the drainage from 

a strip of the eastern slope of the Cascade Range extending from 

Green Pass southward for about 50 miles. It has a number of tributaries among which are Bumping River, heading in Bumping Lakes, 

Rattlesnake Creek, Tieton River, and Cowiche Creek. Of these the 

Tieton is the most important. The headwater streams drain a 

mountainous country.

NACHES RIVER AT ANDERSON'S RANCH, NEAR NILE, WASH.

This station, which was established April 24, 1909, to obtain data 

for power and irrigation projects, particularly in connection with 

the release of stored water from Bumping Lake, is located at Anderson's ranch, 10 miles above Nile post office and 1 mile below the 

mouth of Gold Creek.

Anderson's ditch diverts water from the left bank about 1 mile 

above the station but carries a comparatively small amount.

The gage is a vertical staff in two sections, fixed to a yellow pine 

tree on the left bank directly back of Anderson's house. It is 500 

feet downstream from the cable, from which discharge measurements 

are made.

The right bank is very steep and is covered with alders. The left 

bank is wooded and will overflow in extreme high water. The bed 

of the stream is of gravel and cobblestones and is liable to change 

during freshets.

NACHES RIVER AT OAK FLAT, NEAR NILE, WASH.i

This station, which, is located 2 miles above the mouth of Tieton 

River and half a mile above the heaclgate of the Selah Valley Canal, 

was established June 25, 1904, to obtain data for use in connection 

with the development of the excellent power sites above the station, 

and the equitable distribution of stored water from Bumping Lake 

reservoir.

The original gage was an inclined staff on the left bank near the 

cable section. On April 13, 1909, the cable and gage were moved

L This station called "Naches Eiver near Nile" in the 1907-8 report.
NORTH PACIFIC COAST. 193

800 feet upstream to a point affording better gaging conditions. 

The new gage is of the chain-and-weight type and is fastened to a 

cantilever beam 75 Teet above the cable on the left bank. It was 

installed at an arbitrary datum; therefore, gage records beginning 

April 13, 1909, are not comparable with those made at the old station.

NACHES RIVER BELOW TIETON RIVER, NEAR NACHES, WASH.

This station, which is located 5 miles above Naches, Wash., 600 

feet below the mouth of Tieton River and 600 feet above the headgate of the Wapatox Power Canal, 500 feet above a waste from the
NORTH PACIFIC COAST. 195

Selah Valley canal, was established August 4, 1905, and used as a 

temporary station during the low-water period of 1905. On March 

16, 1909, the station was reestablished and equipment installed for 

making measurements at all stages, in order to obtain data to check 

the records of the station at Oak Flat on Naches River and at Cobb's 

ranch on Tieton River. If the diversion in the Selah Valley can^l 

is added to the discharge, at these stations the results should be comparable with the discharges below. During 1909 the water returning 

to Naches River through this wasteway was not of sufficient amount 

to affect the results.

The gage is in two sections an inclined gage on the left bank in 

the measuring section, which reads to 7.3 feet, and a vertical staff 

which reads from 7.3 to 16 feet. Measurements are made from a 

cable.

The right bank of the stream is rather low, is wooded, and is subject 

to overflow at high stages. The left bank is high, rocky, and will 

not overflow. The bed of the stream is of gravel and cobblestones, 

but will change during freshets. Ice is not likely to affect this 

station except in unusually cold weather.

NACHES RIVER AT NORTH YAKUSA, WASH.

This station was established August 14, 1903, near the mouth of 

Naches River at North Yakima, Wash., and has been maintained 

continuously since that date, except during the intervals when gages 

and gaging equipment were put out of commission by floods.

The data obtained represent the contribution of this drainage 

area to the flow of the Yakima after all irrigation requirements have 

been satisfied. The entire flow of the river during the summer 

months is diverted for irrigation in the Naches and Yakima valleys. 

The station is located below the lowest diversion for irrigation. The 

North Yakima power canal, however, diverts 80 to 200 second-feet 

past the station continuously, a portion of which is wasted into 

Yakima River.

Gages have been maintained below the Northern Pacific Railway 

bridge, and on the highway bridge at North Yakima, and on the 

crib work which extends as a protection for the approach to the 

railroad bridge on the right bank. The present location of the station was selected June 18, 1908, when a chain gage was installed on 

the right bank, 800 feet above the railroad bridge. This gage was 

destroyed October 3, 1909. Gage heights from October 12 to 25, 

1909, were used from a temporary staff gage and reduced to the 

datum of the chain gage. A new chain gage was installed October 

26, 1909, at the same place and at the same datum. The datum of 

these chain gages bears no determined relation to that of the earlier 

gages.

The location of the measuring section has been changed several 

times. - At first measurements were made at the railroad bridge; 

then from the highway bridge 200 feet above the railroad bridge, and 

still later from a cable installed between the two bridges.
198 SURFACE WATER SUPPLY, 1909, PART XII.

The river at the present location of the gage is spanned by a long 

cable reaching from the high bluff on the left bank to an artificial 

dike on the right bank. Discharge measurements are now made 

from this cable.

In the vicinity of North Yakima the river bed is composed of gravel 

and cobblestone and during heavy floods changes so materially that 

a new rating is required after each high-water period. At the present 

location of the gage conditions are such that a good rating curve 

can be developed for all ordinary and medium stages. During the 

winter months ice jams frequently occur at the railroad bridge and 

interfere with the determination of flow to a considerable extent.

NOTE. Ice conditions: During January and the first part of February the river was partially frozen 

over to a depth varying from 2 to 7 inches, but for the greater portion of this period it was open at the gage. 

From Dec. 21 to 31 the gage heights were affected by backwater, caused by slush ice.

BUMPING RIVER DRAINAGE BASIN.

DESCRIPTION.

Bumping River rises in Fish Lake, near Carlton Pass, at an altitude of about 4,300 feet above sea level, and flows northeastward 

about 10 miles to Bumping Lake, which lies about 3,400 feet above 

sea level. Thence it flows northeasterly about 15 miles to its junction with Naches River. About 4 miles above its mouth it receives 

its principal tributary, American River, a stream which heads on the 

high divide of the Cascade Range and flows northeastward. The 

area drained by American River is heavily forested, and its flow is 

supplied largely by snow banks.

Bumping Lake, which is located in the Mount Rainier Forest 

Reserve about 12 miles in a direct line nearly due east from Mount 

Rainier, 46 miles northwest of Naches, and 20 miles southwest of 

Nile, is to be used as a storage reservoir, from which water will be 

released to replace in the lower Naches River water diverted from 

Tieton River for the Tieton project.

BUMPING LAKE NEAR NILE, WASH.

A vertical staff gage was installed on the north shore of Bumping 

Lake about one-fourth mile above the outlet April 27, 1909, to obtain 

data for use in connection with the operation of the storage reservoir. 

When surveys of the lake have been completed it will be possible to 

develop a storage table similar to that for the lakes at the headwaters of Yakima River, to be used in connection with the station on 

Bumping River to determine the natural flow of the river.

BUMPING RIVER AT BUMPING LAKE, NEAR NILE, WASH.

This station was first established June 13, 1906, at a point about 

600 feet below the outlet of Bumping Lake, but records were not kept 

continuously, except for a short period in 1906, until it was reestablished, on July 3, 1909. Its present location is 1,200 feet below the 

site of the Bumping Lake storage dam, 100 feet below the end of the 

spillway. The data obtained here will be valuable in connection with 

the release of stored water from Bumping Lake.

Two gages were installed, one on the bridge at the dam site and the 

other at the cable section 1,200 feet below. Observations were begun 

at the bridge gage April 27 and discontinued September 16. Observations were begun at the cable gage August 7. Simultaneous observations have been obtained and all gage heights are referred to the cable

The right bank of the stream is heavily wooded and overflows at a 

gage height of 5 feet. The left bank is nearly vertical to a point above 

high water and is heavily timbered. The bed of the stream is of 

coarse gravel and cobblestones and is fairly permanent. There is a 

riffle control 200 feet below the station.

AMERICAN RIVER NEAR NILE, WASH.

The station, which is located at a highway bridge three-fourths of 

a mile above the mouth of American River, 35 miles above Naches 

and 20^ miles above Nile, was established April 25, 1909, for use in 

connection with the releasing of water stored in Bumping Lake 

Reservoir.

The gage is a vertical staff fixed to the right abutment of the 

bridge from which measurements are made. On account of the 

isolation of the station it is practically impossible to obtain continuous observations.
204 SURFACE WATER SUPPLY, 1909, PART XII.

The right bank is high and wooded and will not overflow. The left 

bank is low and will overflow in extreme flood. The bed of the stream 

is composed of gravel and cobblestones and is fairly permanent.

Discharge measurements of American River near Nile, Wash., in 1909.

TIETON RIVER DRAINAGE BASIN.

DESCRIPTION.

Tieton River, the principal tributary of the Naches, rises on the 

eastern slopes of the Cascade Range in the vicinity of Cowlitz Pass 

and flows in a general northeasterly direction, joining Naches River 

about .17 miles above the junction of the latter with the Yakima. 

A peculiarity of the river is the turbid milk-white appearance of its 

waters. The water of the South Fork of the Tieton, 25 miles above 

its mouth, is, however, perfectly clear. The forks head in the 

glaciers of a peak of the Cascades known locally as Goat Rock.

About 4 miles below the fork is a remarkable soda spring whose 

waters are very palatable.

The entire flow of Tieton River at low stages will be diverted to 

irrigate lands in the vicinity of North Yakima. The amount so 

taken will be replaced from the Bumping Lake storage reservoir on 

the headwaters of the Naches.

TIETON RIVER AT M ?ALLI8TER MEADOWS, NEAR NACHES, WASH.

This station, which is located 800 feet above the McAllister 

Meadows dam site and about 30 miles southwest of Naches, Wash., 

was established August 28, 1908, to determine the relation between 

the flow at this point and that at the headworks of the Tieton Canal 

and at the mouth of Tieton River, where records of several years 

standing are available.

The station is about 1J miles below the jnouth of South Fork of 

Tieton River, half a mile above the mouth of Wildcat Creek, and 9 

miles above the headworks of Tieton Canal.

The vertical staff gage is nailed to a tree on the left bank, 100 feet 

above the cable, from which discharge measurements are made.

TIETON RIVER AT HEADW-ORKS OF TIETON CANAL, NEAR NACHES, WASH.

This station was first established March 29, 1906, about 1 mile 

below the intake of Tieton Canal, about 21 miles southwest of Naches, 

Wash. On June 27, 1907, the station was moved to a point about 

one-half mile above its former position. It is now located about 500 

feet below the intake of the Tieton Canal, which has recently been 

constructed by the United States Reclamation Service, and 15 miles 

above the mouth of the stream. The river receives no tributaries in 

the immediate vicinity of the station.
208 SUEFACE WATER SUPPLY, 1909, PART XII.

At the former location a vertical staff gage at the cable section was 

us§,d. At the present location two gages have been used, one 20 feet 

below the cable from which measurements are made, the other at 

Weisberger's power plant, 1^ miles downstream. During 1907 and 

1908 the measurements were referred to both gages and a rating curve 

developed for each. From January 1 to April 8, 1909, the powerhouse gage was read, but from a relation curve between the two gages 

these gage heights were reduced to the datum of the cable gage. On 

July 28, 1909, a Bristol automatic recording gage was installed at the 

cable at the same datum as the staff gage there.

As the velocity of the water is rapid, ice does not interfere with the 

determination of flow during the winter season. Great difficulty has 

been encountered in obtaining continuous gage observation, as this 

portion of the country is uninhabited. The conditions at the station 

are not ideal, but it is believed that the results are as reliable as can 

be procured under the natural conditions of channel which exist on 

this stream.

Gage heights for 1909 were furnished by the United States Reclamation Service.

TIETON RIVER AT COBB's RANCH, NEAR NACHES, WASH. 1

This station, which affords data of value in connection with the 

general scheme of the Reclamation Service to develop for irrigation 

the Yakima River drainage basin, has been located at various points. 

From April 24, 1902, to March 7, 1906, it was located just below the 

mouth of Oak Creek on Cobb's ranch. On the latter date it was 

moved to a point 200 feet above the mouth of Oak Creek, thus excluding 19 square miles of drainage area. On March 23, 1907, it was 

moved to the highway bridge at camp No. .1 of the United States 

Reclamation Service; at this point it was between the intake and 

tailrace of the power canal which furnished electric power for construction of two large tunnels on the Tieton canal; no attempt to 

determine discharges was made while the plant was in operation. 

On April 14, 1909, the station was established at Cobb's ranch, below 

the mouth of Oak Creek, a short distance downstream from the point 

where it was first located on April 24, 1902.

The gage is an inclined staff bolted to solid rock on the left bank 

100 feet upstream from the cable. Measurements are made from a 

standard cable equipment. The bed and banks of the stream are 

solid basalt and will not change. The right bank has a gentle slope 

and is lightly covered with soil and is timbered to almost the water's 

edge.

During 1909 the flow of water at this station was affected to a 

small degree by the operation of the power plant at camp No. 1, 

although the station is below the tailrace of the plant.

1 This station called "Tieton River near Naches" in Water-Supply Paper 252, p. 180.

ATANUM CREEK DRAINAGE BASIN. 

DESCRIPTION.

Atanum Creek is formed by the union of North and South forks, 

in Yakima County, near Tampico, Wash. It flows eastward, joining Yakima River about 10 miles below the mouth of Naches River. 

The creek and its South Fork make the greater part of the northern 

boundary of the Yakima Indian Reservation. Its waters are extensively used for the irrigation of Indian lands on the south side and 

for lands belonging to the white settlers on the north. Throughout 

the lower portion of the stream it receives considerable return water 

from this irrigation.
NORTH PACIFIC COAST. 213

NORTH FORK OF ATANUM CREEK NEAR TAMPICO, WASH.

This station, which is located on the North Fork at Goodman's 

ranch, 3 miles above Tampico, Wash., 3J miles above the junction 

with South Fork, and 100 feet below the mouth of Nasty Creek, was 

established August 26, 1907, to determine the low-water flow available for irrigation. It is above all diversions from the stream.

The vertical staff gage is spiked to a small cottonwood tree on the 

left bank.

The conditions at the station are not favorable for very accurate 

results. The current is swift and there were no facilities for making 

measurements except by wading until 1910, when a cable was installed. An estimate of the flow at higher stages has been made by 

extending the discharge curve parallel to the 1910 curve.

The records at the station are not complete, as it was impossible 

to obtain continuous observation of gage height.

NOTE. These discharges for 1909 are based on a rating curve that is fairly well defined. Discharges 

for days having no gage records in the" periods covered are interpolated except as noted: Oct. 1 to 31, 

mean discharge estimated as 17 second-feet, as the observer noted the gage height remained practically 

constant during the month. Discharges for November and Dec. 1 to 6, estimated by intercomparisons 

and hydrograph studies of the stations maintained in Atanum Creek and its tributaries.

NORTH PACIFIC COAST. 215

ATANUM CREEK AT THE NARROWS, NEAR TAMPICO, WASH.

This station was established June 25, 1908. It is located at a point 

in the river locally known as "The Narrows," 3J miles east of 

Tampico, Wash., and 3 miles below the junction of North and 

South forks.

The vertical gage is on the right bank near the highway about 100 

feet above a ford. The flow here is assumed to include all return 

waters from irrigation in the upper part of the drainage basin; but 

the correctness of this assumption is very doubtful, as the situation 

is greatly complicated by an innumerable number of small ditches 

both above and below the station. The records should not therefore 

be considered to represent the natural run-off from this drainage 

area. Gagings are made from a car and cable equipment.

NOTE. These discharges, except for frozen period, are based on a rating curve that is well denned between 

discharges 25 and 190 second-feet. Discharges Jan. 7 to 18 reduced 20 per cent from open-water rating to 

allow for ice conditions. Discharges interpolated for days having no gage record.

NORTH PACIFIC COAST. 217

ATANUM CREEK NEAR YAKIMA, WASH.

This station was established May 11, 1904, at the Northern Pacific 

Railway bridge about 1 mile southeast of Yakima, Wash., and was 

discontinued December 30, 1904. Observations were again resumed 

August 27, 1907, at the same point. The present vertical staff gage 

is located just above the Northern Pacific Railway bridge, and the 

measurements are made from the bridge during high water and by 

wading at low water.

The data obtained at this point are valuable in connection with a 

general study of the reclamation of the Yakima 'Valley now in 

progress by the United States Reclamation Service.

The conditions at this station are unfavorable for accurate results 

and the gage readings are not sufficiently trustworthy to warrant 

their publication. The water at the gage is considerably disturbed 

by riffles. No ice forms to interfere with the determination of 

discharges.

SOUTH FORK OF ATANTTM CREEK NEAR TAMPICO, WASH.

This station, which is located at Shannafelt's ranch, 2 miles above 

Tampico, Wash., and 2£ miles above the junction with the North 

Fork of Atanum Creek, was established August 27, 1907, to obtain 

data for use in connection with irrigation in Yakima Valley. It is 

above all diversions except two small ditches that take water for 

individual tracts of land above the station.

The banks of the stream are very thickly covered with willows and 

brush and the channel is not permanent. The vertical staff gage is 

on the right bank about 500 feet below the observer's house. 

Measurements are made by wading at low stages in the vicinity of 

the gage or from a private bridge one-fourth mile below. There is a 

small by-channel whose waters do not pass the gage, but are measured 

at the bridge. During high stages in the summer time the brush on 

the banks of the stream cause a backwater effect that is not noticeable in the spring and winter, when the leaves are not on the trees.

TOPPENISH CREEK DRAINAGE BASIN. 

DESCRIPTION.

Toppenish Creek, which drains the northern part of the Yakima 

Indian Reservation, enters Yakima River from the west about 25 

miles below the mouth of Atanum Creek. After leaving the hills 

the creek spreads into innumerable sloughs and it is almost impossible to find a point where all the flow can be measured. Its principal 

tributary is Simcoe Creek.

The Reclamation Service proposes to divert water from Toppenish 

Creek near Fort Simcoe to a reservoir on Simcoe Creek.
220 SURFACE WATER SUPPLY, 1909, PART* XII.

TOPPENISH CREEK NEAR FORT SIMCOE, WASH.

This station, which is located 3 miles east and about 1 mile south 

of Fort Simcoe, 1 mile below the highway bridge in sec. 26, T. 10 N., 

R. 16 E., was established February 27, 1909, to obtain data for use 

in connection with the project for the irrigation of lands in the Yakima Indian Reservation.

The station is about 8 miles above Simcoe Creek. The gage is of 

the chain-and-weight type and is attached to a cantilever beam 8. 

feet downstream from the gaging section on the right bank. Measurements are made from a cable. The right bank is high and rocky 

and not liable to overflow. The left bank is low and will overflow at 

high stages. The bed of the stream is of gravel and cobblestones 

and fairly permanent.

TOPPENISH CREEK NEAR WAPATO, WASH.

This station was established March 10, 1909, to replace a station 

10 miles downstream from this point, formerly designated as Toppenish Creek near Toppenish. It is located about 5 miles south 

and 9 miles west of Wapato and 1,000 feet below the mouth of Simcoe
222 SURFACE WATER SUPPLY, 1909, PART XII.

Creek. The data are of value in connection with the proposed project for the irrigation of lands in the Yakima Indian Reservation.

The gage is of the chain and weight type and is fastened to a cantilever beam on the left bank 200 feet above the cable from which 

measurements are made. The banks of the stream are comparatively high, but are subject to overflow at high stages. They are 

covered with a thick growth of willows and brush. The bed of the 

stream is of sand and is liable to change during medium and high 

stages.

TOPPENISH CREEK NEAR TOPPENISH, WASH.

This station was established October 31, 1908, to aid the United 

States Reclamation Service in its general study of the water supply 

available for the development of the Wapato project and was 

abandoned March 3, 1909, in favor of Wapato station. It was 

located at Prahl's ranch, 4 miles south and 4 miles west of Toppenish. 

The chain gage was located on the right bank at the cable.

The conditions at this station, although not favorable for refined 

results, are such that the entire flow is measured except during
224 SURFACE WATER SUPPLY, 1909, PART XII.

will probably carry some water.

The following discharge measurement was made by L. R. Alien:

March 4, 1909: Width, 29 feet; area, 137 square feet; gage height, 4.86 feet; discharge, 210 second-feet.

TOPPENISH CREEK: AT ALFALFA, WASH.

This station, which is located at the highway bridge 300 feet 

above the Northern Pacific Railway crossing, one-half mile east 

of Alfalfa, Wash., and a short distance above the mouth of the 

stream, was established March 6, 1909, to obtain data for use in a 

general study for the reclamation of lands in the Yakinaa Indian 

Reservation. The agricultural lands are very flat and an extensive 

drainage system must be constructed in connection with the proposed 

irrigation system.
NORTH PACIFIC COAST. 225

The gage is a vertical staff on the right and downstream side of 

the bridge from which measurements are made. The banks of the 

stream are comparatively low and will overflow in extreme high 

water. The bed of the stream is rocky and subject to change during 

freshets.

SIMCOE GREEK: NEAR FORT SIMCOE, WASH.

This station, which is located 3' miles north and 2 miles east of 

Fort Simcoe, Wash., in sec. 34, T. 11 N., R. 16 E., at the site for a 

proposed dam where considerable storage can be developed, was 

established February 28, 1909, to obtain data for use in connection 

with the irrigation of lands in Yakima Indian Reservation.
NOKTH PACIFIC COAST. 227

The gage is of the chain-and-weight type and is fastened to a cantilever beam 10 feet above the gage on the right bank. The length of 

the chain is 11.50 feet. Measurements .are made from a foot log. 

The banks of the stream are low and liable to overflow during high 

water. The bed of the stream is gravel and sand and liable to change 

during freshets.

SAT AS CREEK NEAR TOPPENISH, WASH.

Satas Creek drains the southern part of the Yakima Indian Reservation and unites with Yakima River about 8 miles below the mouth 

of Toppenish Creek. The drainage area of Satas Creek at its mouth 

is about 600 square miles.
NORTH PACIFIC COAST. 229

This station, which is located a short distance above the mouth of 

Dry Creek, about 1,000 feet below the public highway and ford, 4 

miles west and 10 miles south of Toppenish, Wash., was established 

November 8, 1908, to obtain data for use by the United States Reclamation Service in connection with the development of the Wapato 

project.

The gage is a vertical staff in two sections, located about 150 feet 

above the measuring section. Discharge measurements are made 

from a cable equipment. The gage is a short distance above a riffle 

control, and a stable relation between gage heights and discharge can 

probably be determined. Owing, however, to its isolated location, 

only weekly readings have been obtained.

a The hign water of Jan. 22,1909, may have been caused by a temporary ice jam below the station combined with some flood water. Discharge estimated for this day.

NOTE. The daily discharges for 1908 and 1909 are based on rating curves applicable as follows: Nov. 

6,1908, to Feb. 17, 1909, fairly well defined above 40 second-feet; Feb. 18 to Dec. 31,1909, well defined; the 

daily discharges for 1908 and 1909 have been obtained from these rating curves by interpolation between 

observer's gage heights and by means of a hydrographic comparison with Toppenish Creek near Fort 

Simcoe.

CANALS IN YAKIMA GALLEY. 

DESCRIPTION.

About 50 private irrigation canals divert water from Yakima 

River and its tributaries. These, together with existing Government canals, irrigate approximately 200,000 acres of land and use 

more than the entire natural flow of Yakima River at low water.

In order to obtain an ample supply during the period of extreme 

low water, temporary storage dams have been constructed at the 

outlets of the three Yakima lakes Keechelus, Kachess, and Clealum. The temporary reservoirs thus formed impound about 80,000 

acre-feet of the flood-water flow of the river, and this, when drawn 

out as needed during the irrigating season, furnishes enough water to 

supply all the land under existing projects.

Only about one-half of the total irrigable area in the Yakima 

Valley, however, is now under irrigation ditches. Extensive projects 

are under way or prospective, by which the United States Reclamation Service proposes to more than double the present irrigated area 

of the Yakima Valley. To do this the low-water flow of Yakima 

River must be increased to more than double its present amount, 

and five large storage dams will be constructed for this purpose. 

Each of the temporary dams at the three Yakima lakes will be 

replaced by an immense permanent dam; the large storage dam at 

Bumping Lake, now nearing completion, and a proposed dam at 

McAllister Meadows, on Tieton River, will also be operated. The
232 SURFACE WATER SUPPLY, 1909, PART XII.

combined capacity of the reservoirs formed by these five large dams 

will aggregate about 800,000 acre-feet. This water, if economically 

distributed, will water practically all the irrigable area in the Yakima 

Valley.

These general statements as to the magnitude of the Yakima 

projects make at once apparent the great importance of hydrographic 

work in this valley. It is obvious that a systematic study of canal 

discharge must be maintained here in order to apportion the stored 

water equitably among users, to procure data which will lead to an 

economical irrigation duty, and to promote sound engineering in the 

construction of future systems and units of this system.

The first hydrographic work on private canals in the Yakima Valley 

was done in 1904. During that year an estimate of discharge was 

obtained on all the larger canals.1 This work was continued in 

1905, and a diversion duty was settled upon, the rights of private 

users estimated, and acreage under private projects determined.2 

After 1905 the private canal work was practically dropped, although 

a few miscellaneous measurements were made in 1906. Nothing at 

all was done in 1907 and 1908.

Owing to large increases in acreage under private and Government 

canals in the years following 1905, it was found that the records of 

acreage, duty, and discharge obtained at that time were fast becoming out of date, and that it would be desirable to obtain a continuous record of private canal discharge in order to handle stored 

waters effectively and apportion the supply equitably among users.

To this end the private canal work was again taken up in 1909. A 

record of flow was secured on the principal ditches for three months 

July, August, and September. This work in 1909 was under the 

supervision of C. F. Gleason, junior engineer of the United States 

Reclamation Service.

NEW RESERVATION CANAL NEAR YAKIMA, WASH.

The New Reservation canal diverts water from the right bank of 

Yakima River 6 miles below North Yakima and just below Union Gap.

The gaging station was established May 9, 1904, at a highway 

bridge 1,000 feet belwo the head gate and above all diversions from
234 SURFACE WATER SUPPLY, 1909, PART XII.

the canal. The canal carries a small amount of water during the 

winter months for domestic uses, but the station records are of 

value only in connection with irrigation.

At present the canal is owned and operated by the United States 

Indian Service. The Wapato project of the United States Reclamation Service, by which the lands on the Yakima Indian Reservation 

will be irrigated, involves as one of its features the enlargement and 

extension of the canal.

The conditions at the station are not favorable for good results. 

The current in the canal is low, and water grass grows profusely in 

the bed and on the banks of the canal, creating backwater at the 

gage as the season advances. Several unsuccessful attempts have 

been made to get rid of this growth, as it interferes with the operation 

of the canal. Discharges therefore must be obtained by the indirect 

method, which will give reasonably accurate results if a sufficient 

number of measurements are secured.

236 SURFACE WATER SUPPLY, 1909, PART XII.

OLD RESERVATION CANAL NEAR WAPATO, WASH.

This canal was constructed and is operated by the United States 

Indian Service for the benefit of Indian lands on the Yakima Reservation.

A station was first established June 7, 1904, at the Northern 

Pacific Railway bridge about 1 mile below the head gate. A slough 

that carries considerable water is taken into this canal at a point 280 

feet below the head gate. The water is carried to a point about 1,000 

feet farther down the canal and there returned to the slough, which 

continues parallel to the river and forms both a wasteway for the 

canal and a channel from which diversions are made for irrigation.

On June 23, 1908, a new station was established 300 feet below the 

head gate of the canal and below the point where the waters from the 

slough are received, and just above the first diversion. The records 

at this point are not comparable with those formerly obtained at the 

railroad bridge, bu.t they represent the amount of water taken from 

Yakima River.

STHTNYSIDE CANAL.

DESCRIPTION. 1

The Sunnyside canal diverts water from the left bank of Yakima 

River in sec. 28, T. 12 N., R. 19 E., Willamette meridian. The canal 

system Was purchased from the Washington Irrigation Co. by the 

United States Reclamation Service in July, 1906. Active operation 

by the Government began in 1907.

The canal is now 60 miles long and parallels Yakima River in its 

general direction. It irrigates practically all the land between the 

canal and the river, and has one lateral Mabton siphon which 

crosses the river to lands on the south side. In all, about 47,000 

acres of land were irrigated in 1909. The operation of this system 

requires that hydrographic work of an exceptional degree of accuracy 

be carried on. During the irrigating season the general scheme of 

operation is effected by dividing the canal and the main lateral into

1 Description abstracted in part from Stevens, J. C., Hydrography as an aid in the successful operation of 

an irrigation system; Proc. Am. Soc. Civil Eng., fol. 36, No. 9, November, 1910, p. 1320; also discussion in 

vol. 36, No. 10, December, 1910, p. 1737. Mr. Stevens's paper contains a detailed account of this canal, 

together with data as to the amount of water used at various points, and gains and losses from seepage.

beats, ranging in length from 3 to 8 miles, each in charge of a patrolman. Gaging stations, where the daily flow is measured, are maintained at the extremities of the beats. The amount diverted from 

the main canal is also measured by means of weirs or special measuring boxes. A complete discussion of the very interesting data that 

have been obtained on this canal system is too lengthy for discussion in this report, so that only the quantity of water diverted from 

Yakima River as measured at the intake is presented in detail.

SUNNYSIDE CANAL NEAR WAPATO, WASH.

This station was established April 22, 1904, although records of 

flow of the canal have been kept ever since it has been in operation. 

It is located 1,000 feet below the intake and above all deliveries.

A new inclined gage was installed April 6, 1907, but the published 

gage heights for 1907 refer to the old vertical staff gage used in 1906. 

On July 31, 1907, a gaging bridge was erected 600 feet below the intake of the canal. In the spring of 1908 a new inclined staff gage 

was set just above this bridge at a different datum. Gage heights 

for 1908 and 1909 are referred to this gage. Gage heights from April 

20 to October 2, 1909 were taken by a Leitz self-registering gage set 

at the same datum as the staff gage at the bridge.

240 SURFACE WATER SUPPLY, 1909, PART XII,

KIONA CANAL NEAR KIONA, WASH.

Kiona canal diverts water from the left bank of Yakima River, 5 

miles upstream from Kiona, in sec. 10, T. 9 N., R. 20 E. It is operated by the Northern Pacific Irrigation Co. The first systematic 

measurements were made in 1904, the station being established 

June 6. The records were interrupted during 1906-7, but were begun 

again on May 7, 1908.

The principal value of the records is in making a study of the discharge of Yakima River at Prosser. A station was established at 

Prosser May 30, 1904, but on account of the impossibility of measuring the discharge at low water the station was abandoned on December 12, 1906. The flow is under the artificial control of the power 

plant and mills located here. The station on Kiona canal was therefore established with the intention of accounting for the inflow and 

diversions between Prosser and Kiona, since at the latter point reliable discharge records of long standing are available. The data 

herewith represents the amount diverted from Yakima River at this 

point.

SNAKE RIVER DRAINAGE BASIN. 

DESCRIPTION.

Snake River, the largest tributary of the Columbia, rises among 

the high peaks of the Rocky Mountains in Yellowstone National 

Park, western Wyoming and northeastern Idaho, heading in the 

divide from which streams flow northward and eastward into the 

Missouri and southward and westward to the Colorado and the lakes 

of the Great Basin. From Shoshcne, Lewis, and Hart lakes, in 

Yellowstone National Park, the South Fork of the river flows southward, broadening into Jackson Lake (4 miles wide and 18 miles long) 

and passing through Jackson Valley (8 miles wide and 40 miles long), 

beyond which, near the Idaho-Wyoming line, it enters a long canyon. 

In the southern part of Fremont County, Idaho, it receives the North 

Fork. Below the junction of the forks the Snake flows westward 

across Idaho to a point near Homedale, near the Oregon-Idaho line, 

where it turns abruptly northward and forms for about 170 miles the 

boundary between Idaho and Oregon, and for 30 miles more that 

between Idaho and Washington. At Lewiston it crosses into Washington, flows northwest, west, and southwest, and joins the Columbia 

near Pasco.

Practically all the important tributaries of Snake River have their 

sources in the high mountains, which are heavily timbered. The 

most heavily timbered areas are those at the head of the South Fork 

in the Yellowstone Park region, the upper areas of Teton, Fall, and 

North Fork of Snake rivers in southeastern Idaho, and those of 

upper Boise and Payette rivers in central Idaho.

Precipitation in the Snake River drainage area ranges from 6 or 8 

inches in the valley to 50 inches at the head of many of the tributaries. In the -higher altitudes the precipitation is practically all in 

the form of snow, but the snowfall in the lower valleys, below American Falls, Idaho, is comparatively light. During the last few years 

there has been considerable rainfall, and dry farming has been practiced successfully in the valleys in the vicinity of Idaho Falls, Blackfoot, and St. Anthony, Idaho. The temperature in these valleys 

ranges from 100° in the summer to 35° below zero in the winter; in 

the Twin Falls and Boise valleys the temperature ranges from 

approximately 110& in the summer to zero in the winter.

The driest year ever known in the drainage basin was 1905; the 

wet years were 1896, 1899, 1904, 1907, and 1909.

Snake River basin has many feasible storage sites, but only a very 

few have been developed. About 300,000 acre-feet can be stored in 

Jackson Lake by a temporary dam which has been constructed by 

the United States Reclamation Service. The largest site is at Swan 

Valley on the South Fork of Snake, and the water available for
250 SURFACE WATER SUPPLY, 1909, PART XII.

storage is approximately 4,000,000 acre-feet. Reservoir sites are also 

found on North Fork of Snake, Fall, Teton, Boise, and Payette 

rivers. Many of these sites will, no doubt, be used at some future 

time by the United States Reclamation Service in connection with 

the Minidoka and Payette-Boise projects.

Although irrigation has reached a high stage of development in 

the Snake River valley, approximately 6,000,000 acre-feet of water 

annually is unutilized. Eventually these flood waters will be stored 

and used to irrigate thousands of acres of arid land.

The streams afford enormous water powers, but only a few sites 

have been developed owing to the lack of market. Large power 

plants have been installed on Payette, Boise, and Snake rivers at 

American Falls, Shoshone Falls, and at the Minidoka dam, and many 

other smaller plants are also in use. (See PI. VI.)

The upper drainage basin of the South Fork comprises the timbered 

mountainous country west and southwest of Yellowstone Lake. The 

east side of its valley is bounded by the Wind River Range, from the 

slopes of which it receives a large number of tributaries, and the west 

side by the high Teton Mountains. Most of the drainage from Teton 

Mountains flows westward through Teton River into North Fork.

Below the junction of North and South forks the Snake receives 

many tributaries, the most important of which are listed in the following table:

SOUTH FOEK OF SNAKE EIVEE AT MOEAN, WYO.

This station, which was established September 21, 1903, to determine the amount of water available for storage at Jackson Lake, is 

located just back of the discontinued post office at Moran, Wyo., and 

about three-fourths of a mile below the United States Reclamation 

Service dam at the outlet of Jackson Lake.

No tributaries enter and no water is diverted between the station 

and the Jackson Lake reservoir, so that the record shows only the 

water flowing over the reclamation dam. The principal tributaries 

below the station are Buffalo, Gros Ventre, John Day, and Salt rivers.

Discharge measurements are made from a car and cable about 150 

feet below the inclined staff gage.

The gage heights are not affected by ice or by artificial control 

below the station, but some irregularity in daily flow is caused by the 

opening and closing of the gates at the dam above. The gage datum 

has remained unchanged since the establishment of the station.

A slight change of bed was observed after the spring floods of 1909, 

but the new rating curve is well defined and the records may be considered excellent.

SOUTH FORK OF SNAKE RIVER NEAR LYON, IDAHO.

This station, which was established April 18, 1903, is located just 

below the highway bridge between Conant and Swan valleys, about 

2 miles below the lower end of Swan Valley.

As the South Fork of Snake River receives no tributaries below 

this point the records show the total amount of water available from
NORTH PACIFIC COAST. 253

the South Fork for irrigation below and for storage in the Swan 

Valley reservoir site just above. Between this station and Jackson 

Lake above a number of important tributaries enter, the run-off at 

Lyon being about four times that at Moran. Chief among these 

tributaries are Buffalo River, which enters about 2 miles below Moran; 

Gros Ventre River, which comes in near Jackson, Wyo., about 30 

miles below Moran; and John Day and Salt rivers, which enter near 

the Idaho-Wyoming line, about 60 miles below Moran. A small 

amount of water is diverted above this station for irrigation on small 

ranches along the river.

The inclined staff gage is located on the north bank about 300 feet 

below the iron bridge and 1 mile above the cable station. The gage 

datum remained unchanged from October 16, 1904, to August 25, 

1909. On August, 25, 1909, a chain gage was constructed directly 

across the river from the inclined gage. Readings on this gage from 

August 26 to December 31, 1909, have been corrected by a constant 

equation to make them comparable with previous readings.

Discharge measurements are made by means of a cable equipment 

at the old site of Wedekinds Ferry.

Winter records are affected by ice. In the daily flow artificial 

control above causes some irregularities, but there is no effect from 

artificial control below.

A slight shifting of channel was observed after the spring floods of 

1909, but a good rating curve has been obtained and the records may 

be considered excellent.

a Mean discharge estimated as 45 per cent of discharge at Neeley Station. 

SNAKE EIVEE AT NEELET, IDAHO.

This station, which was established March 17, 1906, is located onehalf mile north of Neeley post office, Idaho, 4 miles west of American 

Falls, the nearest railway point, and about 32 miles above the Minidoka dam.

The principal tributaries above this station are Blackfoot and Port 

Neuf rivers. Raft River enters the Snake between Neeley and the 

Minidoka dam.

A large amount of water is diverted above this station by canals 

in the Idaho Falls irrigation district. During years of low precipitation Snake River is dry at Blackfoot, but a flow of about 2,000 

second-feet is formed at Neeley by the water from the Blackfoot and 

Port Neuf rivers and from springs in the river channel between 

Blackfoot and Neeley.

A slight shifting of channel was observed after the high water of 

1909. The gage datum has remained unchanged since the station 

was established.

The rating curve is well defined, and the records may be considered 

good.

a Mean estimated on basis of comparisons with other stations in Snake River basin. 

SNAKE EIVEE NEAE MINLDOKA, IDAHO.

The station, which is located at Montgomery's Ferry, on the stage

road from Minidoka to Albion, was established August 3, 1895, and

has been maintained continuously since that time, except during the

year 1900. The station is 6 miles due east of Rupert, Idaho, 10

84547° WSP 272 11 17
258 SURFACE WATER SUPPLY, 1909, PART XII.

miles below the Minidoka dam, and 23 miles above the diversion 

dam of the Twin Falls canals at Milner. Measurements at Montgomery's Ferry indicate the amount of water available for the Twin 

Falls canals, but some seepage water is returned to the river from 

the Minidoka tract below the station.

Raft River is the only important tributary entering Snake River 

between this station and that at Neeley, 44 miles above. No important tributaries enter below the station for a distance of 40 miles.

In dry years the discharge at this station falls below 2,000 secondfeet during the latter part of July and August. As the water rights 

of the Twin Falls canals call for an amount considerably in excess of 

this, the deficiency has to be supplied by stored water from Jackson 

Lake, Wyo.

The records are somewhat affected by ice during the winter months 

and by backwater from the Milner dam, but they may be considered 

as fairly good. Some irregularity of flow is caused by the opening 

and closing of the gates at the Minidoka dam. (See PI. VI, A, p. 250.)

The gage datum has remained unchanged since August 28, 1905.

NORTH SIDE MINIDOKA CANAL NEAR MINIDOKA, IDAHO.

This station, which was established by the United States Reclamation Service May 1, 1909, is located about 350 feet below the head 

gates at the Minidoka dam.

The records show the total amount of water diverted from Snake 

River on the north side at the Minidoka dam. This water is used 

for irrigation on the Minidoka project of the United States Reclamation Service.

The canal runs through a rock cut in the vicinity of the station, 

and the velocity is rather high for obtaining the best results.

SOUTH SIDE MINIDOKA CANAL NEAR MINIDOKA, IDAHO.

This station, which was established by the United States Reclamation Service April 21, 1909, is located just below the head gates at 

the Minidoka dam. Discharge measurements, however, were made 

by engineers of the Reclamation Service during 1908. The records 

show the total amount of water diverted from Snake River by the 

United States Reclamation Service for the irrigation of the South 

Side Minidoka tract.

The stage of the canal is recorded by an automatic gage about 300- 

feet from the headworks, and measurements are made from a suspension footbridge located near the gage.

264 SURFACE WATER SUPPLY, 1909,'PART XII.

SNAKE RIVER AT MILNER, IDAHO.

This station, which is located at Milner, Idaho, about 1,000 feet 

below the diversion dam of the Twin Falls canals, was established 

May 10, 1909, in cooperation with the Twin Falls Land & Water 

Co., to determine the amount of water wasting over the Milner 

dam and available for use for irrigation and power development 

below. In connection with the records obtained at the stations 

on the Twin Falls canals, the records show the total amount of water 

available above the Milner dam.

No important tributaries enter the river between this station 

and the Minidoka station above and Shoshone Falls below.

Water is diverted above the station by two irrigation canals 

at the Minidoka dam and two irrrigation canals at the Twin Falls 

dam in addition to all -the water diverted in the Idaho Falls irrigation district. The normal low-water flow in dry years is already 

appropriated above this point and during the month of August 

must be supplemented by stored water from Jackson Lake, Wyo.

Measurements are made from a car and cable. The low-water 

section of the gage is an inclined staff at the cable section. The 

upper section is a vertical staff located about 15 feet upstream.

The records at this station are not affected by ice. Some irregularity of flow is caused by the opening and shutting of the gates on 

the Milner dam just above.

The gage datum has remained unchanged since the station was 

established. Owing to unfavorable conditions for measuring, the 

records at this station can be considered only fair. A sufficient 

number of measurements have not yet been obtained to develop a 

rating curve.

SOUTH SIDE TWIN FALLS CANAL AT MILNER, IDAHO.

This station, which is located at a highway bridge crossing the canal 

at a point near the Oregon Short Line Railroad depot, about onefourth mile below the canal head gates on the Milner dam, was 

established May 10, 1909, in order to determine the total amount of 

water diverted by the South Side canal for irrigation in the South 

Side Twin Falls tract.

A vertical staff gage is attached to the downstream side of the 

bridge. Discharge measurements are made from the top of a covered water pipe on the upstream side of the bridge.

The records are not affected by ice or by change in control below. 

The flow is regulated at the head gates on the Milner dam.

No change has been made in the gage datum since the gage was 

installed.

SNAKE RIVER AT KING HILL, IDAHO.

This station, which is located at the suspension foot bridge near the 

Oregon Short Line Railroad depot in the village of King Hill, Idaho, 

.and below Twin Falls and Shoshone Falls, was established May 13, 

1909, in order to determine the total flow of Snake River available 

for irrigation and power below Big Wood River, including the return 

water from the Minidoka and Twin Falls irrigation tracts. At present this is the lowest station on Snake River in Idaho.

The river receives only two important tributaries betw.een this 

station and Milner Salmon Falls River, which joins the Snake about 

30 miles above King Hill, and Big Wood River, which comes in about 

20 miles above King Hill. Bruneau River is tributary to the Snake 

about 40 miles below the station.

The total normal low-water flow of Snake River is diverted above 

this station for use in the Minidoka and Twin Falls irrigation tracts. 

During dry years practically the total flow during the irrigating season 

will be derived from return water from these tracts and the flow of 

springs in the canyon.

A vertical staff gage is attached to the left pier of the suspension 

bridge on the downstream side. Discharge measurements are also 

made from the downstream side of the bridge. The gage datum has 

remained unchanged since the station was established.

The records are not affected by ice or by artificial control below, 

but some irregularity of flow is caused by the opening and shutting of 

the gates on the Milner dam.

SNAKE RIVER AT BURBANK, WASH.

This station was established October 2, 1907, by the Burbank 

Power & Water Co., which has undertaken to reclaim several thousand 

acres near Burbank by pumping water from Snake River. Power is 

developed by a plant utilizing the fall in Fivemile Rapids.

Two gages are maintained No. 1, on the right bank, 1,500 feet 

upstream from the intake of the power canal; No. 2, on the left bank, 

at the tailrace of the power plant, 9,200 feet below the upper gage. 

Both gages are graduated in feet and tenths and read from sea level. 

In the published gage-height tables, however, the gage datum has 

been taken as 300 feet above sea level.

Measurements are made from the upstream side of the Northern 

Pacific Railway (Pendleton branch) bridge about 3 miles below the 

power house, 3^4 miles east of Pasco, one-half mile west of Burbank, 

Wash., one-fourth mile above the mouth of the river, and 3^4 miles 

below the foot of Fivemile Rapids.

The channel at the measuring section is straight above and below 

the station. The water is swift at all stages of the stream and will 

probably be confined within the section limited by the abutments 

to the railroad bridge. Gage reading to 28 feet is attached to the 

upstream side of the draw span, but as this gage is affected by backwater from Columbia River, the heights thereon will not accurately 

indicate the discharge. The conditions at the upper gage are favorable for good results. The observed gage heights are not affected 

by backwater from Columbia River and will probably be a stable 

index of the discharge, if suitable corrections can be made for artificial control of water at the head gates.

The construction of a wing dam at the head of the power canal 

in August, 1909, had the effect of raising the water at the upper 

gage an unknown amount. The gage at the tailrace was not installed 

until after the wing dam was completed. It will therefore be impossible to determine the exact effect caused by this wing darn, although
272 SURFACE WATER SUPPLY, 1909, PAET XII.

it is probable that some measure of it can be obtained by comparing 

the records with those observed at Riparia on the Weather Bureau 

gage.

Gage heights at the tailrace are not yet available for publication. 

As these are necessary in the preparation of estimates of discharge 

and also as an insufficient number of discharge measurements have 

been made, no attempt has been made to compute daily and monthly 

discharges.

The following discharge measurement was made October 19, 1909, 

by G. L. Parker:

Width, 700 feet; area, 11,400 square feet; gage height, 336.6 feet; discharge, 26,800 

second-feet. ' Area computed from standard cross section made December 24, 1909. 

Gage height refers to mean sea-level datum.

NORTH FORK OF SNAKE RIVER BASIN. 

NORTH FORK OF SNAKE RIVER NEAR ORA, IDAHO.

The North Fork of Snake River rises in Lake Henry and flows south 

and southwest to its junction with the South Fork.

The gaging station, which was established August 20, 1902, is 

located at the North Fork bridge, 2 miles south of Ora, and 10 miles 

above St. Anthony, Idaho. The records show the total amount of 

water available for storage at this point. The station was discontinued June 30, 1909.

The principal tributaries above are Robinson Creek and Warm 

River, both of which enter about 10 miles above Ora. The principal 

tributaries below are Fall River; which enters about 5 miles below, 

and Teton River, which enters about 20 miles below. No water is 

diverted above the station.

The records are not affected by ice or artificial control above.

The gage datum remained unchanged during the maintenance of 

the station.

84547° WSP 272 H- -18
274 SURFACE WATER SUPPLY, 1909, PART XII.

The following discharge measurement was made May 21, 1909, by 

E. S. Fuller:

Width, 202 feet; area, 575 square feet; gage height, 3.3 feet; discharge, 3,000 second 

feet.

NORTH PACIFIC COAST. 275

NORTH FORK OF SNAKE RIVER NEAR REXBtTRG-, IDAHO.

This station, which is located just below the highway bridge 7 miles 

due west of Rexburg, Idaho, was established April 13, 1909, to determine the total amount of water available from the North Fork of 

Snake River.

It is below all tributaries and diversions. The principal tributaries above are Robinson Creek and Warm, Fall, and Teton rivers, 

the Teton entering about 1 mile above the station.

The vertical staff gage is located on the right bank about 250 feet 

downstream from the highway bridge. Discharge measurements are 

made by means of a car and cable about three-fourths of a mile 

downstream from the highway bridge.

The gage heights are affected by ice during the winter months.

The gage datum has remained unchanged since the station was 

established. The bed of the stream at the gaging section is somewhat shifting, but fairly good records may be obtained by making 

frequent discharge measurements.

NORTH PACIFIC COAST. 277

FALL RIVER AT FREMONT, IDAHO.

This station, which was established January 1, 1904, in order 

to determine the amount of flood water available for storage in 

the Fall River meadows reservoir site, is located at the discontinued 

Fremont post office about 9 miles southeast of Marysville, Idaho.

As the river receives no important tributaries below the station 

the records show practically the total run-off from the Fall River 

drainage area. Two comparatively small irrigation canals divert 

above the station.

The records are affected by ice during the winter months but are 

not affected by artificial control above or below. The gage datum 

has remained unchanged since the station was established. The 

cross section is rough but permanent.

This station was discontinued June 30, 1909.

The following discharge measurement was made by E. S. Fuller:

May 22, 1909: Width, 144 feet; area, 445 square feet; gage height, 3.9 feet; discharge, 

2,470 Becond-feet.

Daily gage height, in feet, and discharge, in second-feet, of Fall River at Fremont, Idaho,

for 1909.

TETON RIVER NEAR ST. ANTHONY, IDAHO.

This station, which was established April 23, 1903, to obtain data 

for use in connection with proposed irrigation work on Teton River 

and to determine the amount of flood water available for storage, 

is located at the bridge on the stage road from St. Anthony to Victor, 

about 7 miles from St. Anthony.

No tributaries of any importance enter below the station. The 

principal tributaries above are Canyon Creek, entering about 10 

miles above, and North Fork, entering about 20 miles above. The 

Teton canal diverts water above the station.

The records are somewhat affected by ice during the winter months, 

but are not affected by artificial control above or below. The 

gage datum has remained unchanged since the station was established. 

The records may be considered good.

This station was discontinued June 30, 1909.

The following discharge measurement was made by E. S. Fuller:

May 23, 1909: Width, 98 feet; area, 498 square feet; gage height, 3.75 feet; discharge, 2,070 Becond-feet.

Daily gage height, in feet, and discharge, in second-feet, of Teton River near St. Anthony,

Idaho, for 1909.

BLACKFOOT RIVER DRAINAGE BASIN. 

DESCRIPTION.

Blackfoot River rises on the western slopes of the Preuss Range, 

in the southeastern part of Bannock County, Idaho, and flows northwestward to a point about 6 miles east of Presto, whence its course 

is southwest ward to its junction with the Snake at Blackfoot. It is 

about 80 miles long and much of its drainage area is mountainous.

BLACKFOOT RIVER NEAR HENRY, IDAHO.i

This station, which is located 200 feet below the wagon bridge at 

Rockyford, 1 mile below the dam, and 45 miles from Rossfork, the 

most convenient railway station, was established July 15, 1908, to

i This station called "near Rossfork" in Water-Supply Paper 252, p. 231.
280 SURFACE WATER SUPPLY, 1909, PART XII.

determine the amount of water available for storage at the reservoir 

at Blackfoot Marsh, now under construction by the Indian Office. 

The dam and station are near Henry post office.

No tributaries enter the river between this station and the dam 

above and no water is diverted. The principal tributaries between 

the station and the mouth of the canyon below are Corral, Brush, 

and Wolverine creeks.

A vertical timber gage is set on the left bank above the cable from 

which discharge measurements are made.

The records are somewhat affected by ice during the winter, but 

a fairly good estimate of winter flow can be made. Gage heights 

show no effect of artificial control below, but some irregularity in 

daily flow may be caused by operations at the dam above.

The gage datum has remained unchanged since the station was 

established.

BLACKFOOT RIVER NEAR SHELLEY, IDAHO.

This station, which is located in sec. 7, T. 2 S., R. 38 E., Boise 

meridian, about 1^ miles above the mouth of the canyon, 18 miles 

northeast from Blackfoot, and about 10 miles southeast from Shelley, the nearest post office and railway station, was established June 

26, 1909, to determine the total flood waters available from Blackfoot River for storage.

The principal tributaries that enter the Blackfoot between this 

station and the Indian Office dam, 37 miles above, are Corral Creek, 

30 miles above; Brush Creek, 15 miles above; and Wolverine Creek, 

1 mile above. The river receives no important tributaries below the 

station and no important diversions above.

A vertical staff gage hi a stilling box is located on the right bank 

20 feet above the cable from which discharge measurements are 

made. A Friez improved automatic gage is located on the right 

bank 10 feet above the cable, inclosed in a small gage house. The 

automatic gage is set weekly to correspond with the staff gage.

During December and January ice makes it impossible to get good 

records. The gage heights are unaffected by control below, but 

some irregularity of flow is caused by the operation of the gates on 

the Indian Office dam above. The gage datum has remained 

unchanged since the station was established.

BLACKFOOT RIVER NEAR PRESTO, IDAHO.

This station, which is located on the ranch of James Just, 2 miles 

east of the discontinued Presto post office and about 15 miles northeast from Blackfoot, Idaho, was established April 17, 1903, to determine the amount of flood waters available for storage. The station 

was discontinued December 31, 1909.

No tributaries enter the river between this station and the one in 

the canyon 5 miles above, and there are no important tributaries 

below. Between this station and the station in the canyon four 

small irrigation canals divert about 50 second-feet of water during 

the irrigating season. This is about equal to the average summer 

inflow between this station and the Indian Office dam, 42 miles above.

Discharge measurements are made by means of a cable equipment 

located about one-fourth mile below the inclined staff gage.

The records are not affected by artificial control below, but some 

irregularities in daily flow occur, due to artificial control and ice conditions above. The gage datum has remained unchanged since the 

station was established.

SEEPAGE INVESTIGATIONS ON BLACKFOOT RIVER, IDAHO.

An investigation of the amount of seepage water returning to 

Blackfoot River between Rockyford dam, near Henry post office, 

Idaho, and the cable station near Presto, Idaho, a distance of about 

42 miles, was made in cooperation with the United States Indian 

Office, October 10-15, 1909, along lines similar to the investigations 

on Boise River of previous years.1

i For data on the seepage investigations made on Boise River, Idaho, in 1898, 1901-1903, and 1905-1908, 

see Water-Supply Paper 252, pp. 248-252.
NORTH PACIFIC COAST. 287

Weather conditions for this were ideal, and the maximum variation in stage of the river as recorded by a Friez automatic gage 

located at the mouth of the canyon about 5 miles above Presto, 

Idaho, showed only 0.01 foot. As the variation in the river during 

the investigation was so slight the measurements were treated as 

though made instantaneously.

A rapid reconnaissance was made between Rockyford and Presto 

and eight sections were chosen for river measurements, including 

these two. Of these, the section near Henry and the four sections 

chosen below Brush Creek were all good gaging sections, but the 

other three were less satisfactory, owing to rough stream bed and 

high velocities.

Twenty-one creeks and springs were found to be discharging water 

into the river between Rockyford and the mouth of the canyons, and 

all these were measured with a current meter. Between the mouth 

of the canyon and the Presto station four canals are taken out, but 

of these, only two were carrying water during the period covered by 

the investigation.

The results of all the measurements made are tabulated below.

BIG LOST RIVER NEAR CHILLY, IDAHO.

Big Lost River rises in the southern part of Ouster County, Idaho, 

flows northeastward to a point about 3 miles southeast of Chilly, then 

turns abruptly and flows southeastward for about 50 miles. About 

15 miles below Lost River it makes another turn to the northeast and 

25 miles farther on its waters are lost in a sink.

The gaging station, which was established April 25, 1904, discontinued August 31, 1906, and reestablished July 1, 1907, is located 

at Ho well's ranch, about 30 miles upstream from Mackay, Idaho, 

7 miles from Chilly, the nearest post office, and 3 miles above 

Kinickinick Point. The records show the total amount of water 

available for storage at the reservoir site 3 miles above Mackay.

The stream receives no important tributaries below the station, 

and there are no important diversions above.
NORTH PACIFIC COAST. 289

The records are not affected by artificial control above or below, 

but ice prevails during the winter months to such an extent that it 

is necessary to discontinue readings about three months. The gage 

datum has remained unchanged since August 20, 1906. The channel 

section is permanent.

RAFT RIVER DRAINAGE BASIN. 

DESCRIPTION.

Raft River rises on the eastern slope of Goose Creek Mountain 

in the southwestern part of Cassia County, Idaho, flows southeastward a short distance into Utah, then turns to the east and north, 

reenters Idaho, and takes a general northerly course to its junction 

with Snake River about 12 miles above the Minidoka dam.

RAFT RIVER NEAR BRIDGE, IDAHO.

This station, which is located at a wagon bridge on the Langford 

ranch, about 4 miles from Bridge, the nearest post office, and about 

25 miles southeast of Albion, Idaho, in sec. 27, T. 15 S., R. 26 E., 

Boise meridian, was established September 18, 1909, to determine 

the amount of flood water available for storage in a reservoir site 

4 miles above.

The river receives no important tributaries above the station. 

The principal tributaries below are Clear Creek, which enters about 

8 miles below, and Cassia Creek, entering about 15 miles below. 

All the normal low-water flow is already appropriated by ranches 

above the station.

The vertical staff gage is attached to the right abutment on the 

downstream side of the bridge, from which discharge measurements 

are made.

The records are affected by ice during the winter months but 

are not affected by artificial control above or below.

The gage datum has remained unchanged since the station was 

established.

CASSIA CREEK NEAR CONANT, IDAHO.

This station, which is located at Conant's ranch in sec. 24, T. 13 S., 

R. 25 E., about 15 miles southeast of Albion, Idaho, and about 5 

miles above the junction of Cassia Creek with Raft River, was established September 18, 1909, to determine the amount of flood water 

available for storage in connection with a Carey Act project on 

Cassia Creek.

The creek receives no tributaries below the station. All the 

normal low-water flow is already appropriated by ranches above 

the station.

The vertical staff gage is about one-eighth mile downstream from 

the highway bridge at Conant's ranch.

Low-water measurements are made by wading at the gaging section. At present there is no equipment from which to make highwater measurements.

The records are somewhat affected by ice during the winter months, 

but are not affected by artificial control above or below.

The gage datum has remained unchanged since the station was 

established.

GOOSE CREEK NEAR OAKLEY, IDAHO.

Goose Creek rises on Sugar Peak, in the extreme northeastern 

corner of Nevada, flows southeast, east, and then in a general northeasterly course to its junction with the Snake, near Burley, in the 

northern part of Cassia County, Idaho. The creek is about 70 miles 

long (map measurement) and receives tributaries that drain both the 

eastern and the western slopes of Goose Creek Mountains.

The gaging station, which is located at a wagon bridge 1 mile above 

the Oakley dam site and about 6 miles south of Oakley, Idaho, the nearest post office, was established May 26,1909, to determine the amount 

of water available for storage, in connection with a Carey Act project.

Trapper Creek joins Goose Creek one-eighth mile above the 

station. The principal tributaries below are Birch, Basin, and 

Antelope creeks.

The vertical staff gage is fastened to the downstream side of the 

bridge, from which the discharge measurements are made.

 The records are somewhat affected by ice during the winter.

The gage datum has remained unchanged since the station was 

established.

BIG COTTONWOOD CREEK NEAH OAKLEY, IDAHO.

Big Cottonwood Creek rises in the western part of Cassia County 

and flows northerly and northwesterly to its junction with the Snake 

River at Murtaugh, in Twin Falls County, about 5 miles west of Milner. The creek is about 25 miles long and its tributaries are few and 

unimportant.

The gaging station, which is located just above Roark's ranch, 

about 10 miles northwest of Oakley, the nearest post office, and 

about 15 miles south of Milner, the nearest railway station, was 

established November 27, 1909, to determine the amount of water 

available for a proposed Carey Act land segregation. The staff gage 

is spiked to a cottonwood tree on the right bank.

Measurements are made by wading, except during extreme high 

water.

ROCK CREEK NEAR ROCK CREEK, IDAHO.

Rock Creek rises in the eastern part of Twin Falls County and flows 

in a general northerly and northwesterly direction about 30 miles 

to its junction with Snake River, 5 miles northwest of Twin Falls. 

Its principal tributary is Cottonwood Creek.

The gaging station, which is located 011 the ranch of E. M. Crockett, 

about 3 miles above Rock Creek post office, was established November 28, 1909, to determine the amount of water available for a proposed Carey Act land segregation.

The gage is on the left bank about 50 feet below the footbridge 

and is spiked to a log from which discharge measurements are made.

A good rating covering the range of stages in 1909 has been obtained and the records may be considered good.

SALMON FALLS RIVER DRAINAGE BASIN. 

DESCRIPTION.

Salmon Falls River rises in the northern part of Elko County, Nev., 

flows in a general southerly direction for about 25 miles, then turns 

abruptly and flows irregularly northward to its junction with Snake 

River, near Austin, in the northwestern part of Twin Falls County, 

Idaho. From source to mouth the river is about 100 miles long.

SALMON FALLS RIVER AT SAN JACINTO, KEY.

This station, which is located about 7 miles north of the San 

Jacinto ranch and about 20 miles south (by road) of Salmon dam, 

was established September 17, 1909, to take the place of the station 

established earlier in the year at the Salmon dam site 15 miles below, 

as the latter station will soon be flooded out by backwater from the 

dam now under construction. The records of this new station give 

practically the same data as those obtained at the lower station.

Shoshone Creek enters the river just above the station and Cedar 

Creek about 30 miles below. The vertical staff gage is located on 

the right bank at the mouth of the canyon and about 350 feet downstream from the mouth of Shoshone Creek.

Low-water measurements can be made by wading. At present there 

is no cable equipment from which to make high-water measurements

The gage datum has remained unchanged since the station was 

established. No rating curve has yet been deduced from the observations.

SALMON FALLS RIVER NEAR TWIN FALLS, IDAHO.

This station, which is located about 35 miles south of Twin Falls 

and about three-fourths of a mile upstream from the Salmon dam, 

was established May 31, 1909, to determine the amount of water 

available for storage in the Salmon Falls River reservoir now under 

construction.

Shoshone Creek enters the river about 15 miles above the station 

and Cedar Creek enters about 15 miles below.

The cable equipment from which measurements are made at ordinary and high stages is just upstream from the highway bridge on 

the road from Salmon dam to Cedar Creek. Low water measurements are made by wading. A vertical staff gage is located on the 

left bank about 15 feet upstream from the cable.

The records are affected by ice during the winter months but in 

1909 were not affected by artificial control above or below. As soon 

as the Salmon dam is completed this station will be flooded out and 

the records must be discontinued.

The gage datum has remained unchanged since the station was 

established. A-good rating curve has been obtained and the records 

during the open-water season may be considered excellent.

CEDAR CREEK NEAR ROSEWORTH, IDAHO.

This station, which is located about 10 miles south of Roseworth, 

the nearest post office, about 25 miles south of Buhl, the nearest railway point, and about 7 miles west of Salmon dam, was established 

May 30, 1909, to determine the amount of water available for storage 

in connection with a Carey Act project on Cedar Creek.

Cedar Creek joins Salmon Falls River about 12 miles below the 

station. House Creek, the main source of supply, enters about 2^ 

miles above.

The gage is about 100 feet above the mouth of the West End Twin 

Falls Irrigation Co.'s tunnel and immediately upstream from the 

Cedar Creek dam site at Butte, and about 1 mile downstream from 

the mouth of the canyon.

Discharge measurements are made from a plank across the stream 

at the gage.

There is said to be some gain from seepage between this station 

and House Creek. When the Cedar Creek dam is completed this 

station will be flooded out by backwater and new stations will 

have to be established on Cedar Creek and House Creek above their 

junction.

The records are probably not seriously affected by ice, and during 

1909 there was no effect from artificial control above or below.

BIG WOOD RIVER NEAR SHOSHONE, IDAHO.

Big Wood (Malade) River rises near Galena Peak, in the northern 

part of Blaine County, Idaho, and flows southward and southwestward to its junction with Snake River in the western part of Lincoln 

County. It is about 100 miles long and drains an area of about 4,500 

square miles in extent. It receives a number of tributaries, the most 

important being Camas Creek and Little Wood River.

This station, which was established June 5, 1905, discontinued 

December 31, 1906, and reestablished March 7, 1908, is located at 

A. D. Silva's ranch, 1 mile below the steel wagon bridge and 7 miles 

northwest of Shoshone, Idaho.

The records of this station show the total amount of water available 

for storage in the reservoir now under construction at the Cottonwoods, 15 miles above. The principal tributaries are Camas Creek, 

which enters about 26 miles above the station, and Little Wood River, 

entering about 15 miles below.

During the winter months the records are slightly affected by ice. 

They are not affected by artificial control below, but during the irrigating season practically the total flow of the river is diverted above. 

The gage datum has remained unchanged since the station was 

established.

The channel is permanent and a very good rating curve has been 

obtained. (See PL III, p. 26.)

LITTLE CANYON CREEK AT GLENNS FERRY, IDAHO.

Little Canyon Creek, a stream about 20 miles long, joins Snake 

River from the north at Glenns Ferry.

The gaging, which is located in the western part of the town of 

Glenns Ferry, Idaho, at the highway bridge on the road from Glenns 

Ferry to Hammett, just above the point at which the creek crosses 

the tracks of the Oregon Short Line Railroad, was established 

November 20, 1909, to determine the amount of water available for 

the irrigation of Carey Act lands.

The staff gage is attached to the bridge, from which discharge 

measurements are made at high stages. Measurements at low water 

are made by wading.

The records of this station show the total discharge of the creek 

into Snake River. No rating has yet been obtained.

BENNETT CREEK NEAR MEDBURY, IDAHO.

Bennett Creek rises in the southern part of Elmira County and 

flows southward into Snake River about 12 miles west of Glenns 

Falls. It is about 25 miles long.

The gaging station, which is located at the highway bridge, about 

2 miles west of Medbury, Idaho (Hammett railroad station), and 

about one-half mile north of the tracks of the Oregon Short Line 

Railroad, was established November 20, 1909, to determine the 

amount of water available for irrigation of Carey Act lands.

The records show the total discharge into Snake River from the 

Bennett Creek drainage.

The staff gage is attached to the bridge, from which discharge 

measurements are made at medium and high stages. Measurements 

at low water are made by wading.

The following discharge measurement was made by O. W. Hartwell:

December 14, 1909: Width, 20 feet; area, 18.8 square feet; gage height, 0.80 foot; 

discharge, 30.7 second-feet.

BRUNEAU RIVER DRAINAGE BASIN. 

DESCRIPTION.

Bruneau Kiver rises in northern Nevada, flows in a general 

northerly direction, and enters Snake Kiver in Owyhee County, Idaho. 

Its basin is of a rolling character and is devoted to stock raising. Systematic measurements on this river have been maintained by Andrew 

J. Wiley for the Owyhee Land & Irrigation Co., immediately below 

the head works of its canal system, 10 miles east of Grand view, Idaho.

BRUNEAU RIVER NEAR HOT SPRING, IDAHO.

This station, which was established July 3, 1909, to determine the 

amount of water available for storage in connection with irrigation 

on the Bruneau tract, is located at Dunham's ranch, about 2 miles 

upstream from the Hot Spring post office.

The principal tributaries above are West Fork, which enters the 

Bruneau about 35 miles upstream; East Fork, which comes in about 

15 miles above; and Hot Creek, which is tributary about one-half 

mile above the station. No important tributaries enter the river 

between the station and Snake River, about 20 miles below.

The vertical -staff gage is located about one-fourth mile above 

Dunham's farmhouse on the right bank and about 600 feet below 

the cable station.

The records are not affected by ice or by artificial control above or 

below. The gage datum has remained unchanged since the station 

was established.

BRTTNEATJ RIVER NEAR GRANDVIEW, IDAHO.

This station, which was established May 1, 1909, to determine the 

amount of water wasting into Snake River over the Bruneau dam, is 

located about one-fourth mile below the headworks of the Owyhee 

Land and Irrigation Co.'s canal system, where a station was maintamed from 1895 to 1903. It is 10 miles east of Grandview and about 

8 miles west of Bruneau, Idaho.

The gage installed in 1895 was used until March 6, 1903, when a new 

staff gage was set at the same datum, 25 feet upstream on the left 

bank, at the ford on the old stage road about 1 mile above the mouth 

of the river. On May 1, 1909, readings on this gage were resumed and 

continued until November 6, 1909, when a new vertical staff gage was 

installed at the same datum about 46 feet upstream on the left bank.

High-water measurements are made from a boat and stayline 

attachment. Low-water measurements can be made by wading 

about 300 feet downstream from the gage.

As no record has been kept of the water diverted by the canal system, 

the discharge as measured at this station does not show the run-off 

from the drainage area above the station. The capacity of the canal 

system is about 540 second-feet.

The records will probably not be seriously affected by ice but will 

be affected by changes in the gates on the dam above.

SUCCOR CREEK NEAR HOMEDALE,, IDAHO.

Succor Creek rises in the Mahogany Mountains, in the eastern part 

of Malheur County, Oreg., flows northeastward, and joins Snake River 

near Homedale, Idaho.

This gaging station, which was established March 19, 1903, in order 

to determine the amount of water which wastes annually into Snake 

River, was originally located at a small truss bridge built to carry a 

flume, about half a mile above the mouth of the creek. It has been 

moved twice, the second time on August 28, 1907, when the cable was 

moved about one-fourth mile downstream. On January 24, 1908, a 

new chain gage was installed at a point about 200 feet above the cable. 

This gage was washed out January 20, 1909, but was replaced on 

January 23, 1909, by a new staff gage with the same datum.

The station is below all tributaries and diversion canals. The 

entire low water flow is diverted for irrigation purposes above.

OWYHEE RIVER DRAINAGE BASIN.

DESCRIPTION.

Owyhee Kiver rises in the Independence National Forest in the 

north-central portion of Nevada, flows north, then northwest across 

the corner of Idaho and into Oregon, where it turns abruptly and 

flows northeastward to its junction with Snake River, near Nyssa, 

Oreg., opposite the mouth of Boise River in Idaho. The total
NORTH PACIFIC COAST. 315

length of the river is about 220 miles, and the drainage area comprises 11,100 square miles.

The country drained is an exceedingly arid desert", the annual 

precipitation ranging from 6 to 9 inches, the larger part occurring as 

snowfall. Forests are entirely lacking except on the extreme headwaters, and even there they are small. The general elevation of 

the river basin is about 4,000 feet, and the altitudes have but little 

effect on the precipitation. The streams are frequently frozen for 

considerable periods during the winter months, so that records for 

this part of the year are subject to inaccuracies. The low-water 

flow of this stream at the mouth is nearly all taken by a large canal 

for the irrigation of lands lying between Owyhee and Malheur rivers. 

On the upper stretches of the river conditions are favorable for 

impounding the flood and winter flows for irrigation during the 

summer months.

OWYHEE RIVER AT OWYHEE, OREG.

This station, which was established March 26, 1890, discontinued 

October 3, 1896, and reestablished August 27, 1903, is located at 

the county bridge half a mile from Owyhee post office and 3 miles 

above the mouth of the stream.

The data have practical value in connection with irrigation 

development.

The Owyhee ditch diverts water 6 miles above the gaging station. 

A record of the flow of this canal was kept during the irrigating 

season of 1905 at a point 2 miles below the intake. The maximum 

diversion during this period was 210 second-feet, in June. There 

are five wasteways on this canal, the first two being above the 

gaging station. The natural flow of the river at this point must 

therefore be obtained by adding the diversion hi the canal to the 

flow obtained at the river gaging station, and subtracting from 

this sum the amount returning from the first two waste ways.

The entire low-water flow is diverted for irrigation and the flow 

measured at this point at such times is only seepage water.

During the winter months the gage heights are somewhat affected 

by ice, but the periods during which the stream is ice-bound are 

short, and even at such.times approximate records can be obtained. 

The datum of the gage has not been changed since its installation in 

1903.

No discharge measurements were made during 1909.

This station was last inspected May 28, 1908. The accuracy of the 

daily and monthly discharges given below is, therefore, dependent 

upon the permanency of conditions of flow and of the elevation of 

the gage since that date. As the flow is controlled by a riffle 200 

yards below the station and measuring conditions are favorable for 

good results, the records are believed to be reliable.

NOTE. These discharges are based on the 1908 rating curve, which is fairly well defined. Discharges 

from Dec. 12 to 31 reduced 10 per cent on account of ice conditions. January discharges computed as for 

open-channel conditions. Those for Jan. 1 to 7 may be somewhat too large due to probable ice effect.

a The drainage area for this station has been revised on the basis of later map measurements.

BOISE EIVEE DKAINAGE BASIN. 

BOISE RIVER NEAR HIGHLAND, IDAHO.

Boise River rises in the western part of Blaine County and flows 

westward across Elmore, Ada, and Canyon counties to its junction 

with Snake River. Its drainage area is mountainous and well 

wooded.

The gaging station was established July 27, 1905, to replace the 

station at Boise. It is located 3 miles southwest of Highland post 

office, about 8 miles above the old Boise station, and 15 miles east of 

Boise, the nearest railway point.

The records show the total 41ood waters available from. Boise River 

and are used in connection with the distribution of the low-water 

flow, all of which is used for irrigation below. (See PL VII.)

Moores Creek joins the river 2 miles above the station. The 

tributaries below are unimportant. But little water is diverted 

above the station.

Measurements are made from a cable and car at all stages. The 

gage is on the left bank of the stream about 100 feet below the cable.

The gage heights are somewhat affected by ice during the winter 

months. . The gage datum remained unchanged during 1909.

NOTE. These discharges are based on rating curves applicable as follows: Jan. 1 to Mar. 31, fairly welldefined; Apr. 1 to 24, indirect method for shifting channels; Apr. 25 to June 5, fairly well defined; June 6 

to July 23, fairly well denned; July 24 to Nov. 8, indirect method for shifting channels; Nov. 9 to Dec. 31, 

fairly well denned.

The slush ice in January probably did not seriously affect the open-channel conditions.

CANAL SEEPAGE IN BOISE VALLEY, IDAHO.

During July, 1909, an investigation was conducted jointly by the 

United States Reclamation Service, United States Geological Survey, 

and the State of Idaho to determine the amount of loss by seepage 

and evaporation in the canals in Boise Valley. This task was rendered exceedingly difficult by the short time available, which necessitated the use of the so-called instantaneous method of measurement, and also by the fact that the managers of the canal systems were 

tmwilling to have the flow of water regulated for any considerable 

length of time in the main canals for fear of complaints from water 

users. Some fear was also felt that the experiments might injure their 

rights to use of water.

Measurements were made on the Farmers Union canal July 9 

and 13, on the Settlers canal July 15, on the Eureka canal July 19, 

on the Caldwell High Line canal July 21, and on the Middleton Water 

Co. canal July 24.

Gages graduated to be read to 0.01 foot were so located at the measuring sections that they immediately indicated any change in the 

water level of the canal, but were not subject to wave action. These 

gages were read every few minutes during measurements.

The vertical velocity curve method was employed in making the 

measurements, the measuring points being at 0.25-foot intervals 

from the surface, and the bottom point being as near the bed of the 

canal as the meter could be held. The bottom point of two of the 

meters used was 0.45 foot; the third meter was used with the weight 

above the cups and could be lowered to 0.15 foot of the bottom. 

The slight difference in the ratings of the meter was negligible.
320 SUBFACE WATEB SUPPLY, 1909, PABT XII.

The canal sections were selected with reference to (1) the character 

of canal between stations, whether bottom, side-hill, or bench canals; 

(2) the regularity of flow; (3) the character of bottom and crosssection of the canal at station; (4) the length of section to be measured; and (5) the number of laterals to be measured or turned off.

The method of procedure in making a test on a canal was as follows:

Measurements were begun at the upper station of the canal by a 

party consisting of two engineers, and were carried on quickly until 

all the other sections had been measured. All water diverted from 

the main canal between measuring sections by laterals was also 

measured and accounted for. In making the measurements on the 

Farmers Union canal on July 13 three parties were employed throughout the day, each party measuring at each of the three sections in 

turn. The headgates at the river were regulated and the water 

surface in the canal held all day at as nearly a constant level as 

possible. .

The summary of the results obtained in this seepage investigation 

is given in the following table:

a Results at station C discarded as not being reliable.

6 This loss is balanced by waste water entering the canal from higher lands.

From the foregoing observations it would appear that in the 

bottom canals, when the land on either side of the canal is irrigated, 

there is practically no loss from seepage and evaporation, but that 

in nearly all there is a gain and that in some of the canals the gain 

is very marked. The side hill and bench canals lose slightly, averaging about 1 per cent per mile for canals carrying from 100 to 200 

second-feet. In nearly all canals or sections of canals on the river
NORTH PACIFIC COAST. 321

bottoms the seepage and waste water from irrigated lands above 

a canal tends to compensate for losses by seepage and evaporation. 

The bench-land canals have a much greater apparent loss than canals 

in the lower or bottom lands.

MALHEUR RIVER DRAINAGE BASIN. 

DESCRIPTION.

Malheur River rises in the eastern part of Harney County, flows 

northward, receiving the Middle Fork near Riverside, the North 

Fork near Juntura, and Bully Creek at Vale, and discharges into 

Snake River at Ontario. Its drainage area, which includes the 

southeastern slope of the Blue Mountains and the eastern border 

of the divide that marks the boundary of the Great Basin in Oregon, 

is fan shaped, the outer border extending 140 miles along the 

mountain summits. The basin at the mouth of the river measures 

4,150 square miles and at Riverside 1,910 square miles.

Elevations within the basin range from 5,000 feet at the headwaters to 2,000 at the mouth. The country is generally rough and 

broken and is largely covered with sagebrush. Irrigation is restricted 

to the lower lands immediately adjoining the streams. The headwater areas are lightly forested, but elsewhere the area is timberless 

and is utilized as range for cattle and sheep.

The mean annual rainfall ranges from 16 inches on the headwaters to 10 inches at Vale. During the winter months the streams 

are icebound for part of the time.

This area offers some exceptional advantages for irrigation, for in 

it are combined large storage possibilities, ample stream flow, and 

enormous areas of desert lands.

MALHEUR RIVER AT VALE, OREG.

This station was originally established March 20, 1890. Observations were suspended June 30, 1891, resumed January 1, 1895, suspended again September 30, 1896, and again resumed May 20, 1903. 

They were interrupted from April 1, 1907, to May 29, 1908. The 

station at present is located within the city limits of Vale, one-fourth 

mile below the mouth of Bully Creek and 2J miles above the mouth 

of Willow Creek. The datum of the chain gage has not been changed 

since May 20, 1903.

The data obtained at this station are very valuable, as the waters 

of the stream are extensively used for irrigation, the low-water 

flow being entirely appropriated for this purpose. Measurements 

do not show the natural flow of the stream because of diversions 

for irrigation above.1

MIDDLE FORE OF MALHETTR RIVER ABOVE SOUTH FORK, AT RIVERSIDE, OREG.

This station, which is located about 200 feet above the mouth of 

South Fork of Malheur River at Riverside, Oreg., was established 

January 3, 1906, to determine the amount of water available for 

storage in the Warm Springs reservoir site about 6 miles above. At 

present a large part of the summer flow is used for irrigation in small 

ditches that water the lands immediately contiguous to the stream.

A temporary vertical staff gage, located about 400 feet above the 

cable, was used until January 24, 1906, when it was replaced by a 

permanent sloping staff gage 15 feet below the cable. This was used 

until washed out on March 29, 1906. It was replaced, May 8, 1906, 

by a chain gage at the same location and datum. The gage readings 

during the interval were read from a temporary gage and reduced to 

the chain-gage datum. The station was discontinued March 31, 

1907, on account of its inaccessibility and excessive cost. It was,
324 SURFACE WATER SUPPLY, 1909, PART XII.

however, reestablished December 15, 1908, and a new vertical staff 

gage installed about 200 feet above the cable on the left bank. An 

auxiliary chain gage was also installed at the cable in order to determine a relation between the gages at the two locations, but as the 

chain gage was destroyed on January 15, 1909, this relation was not 

determined. It is believed, however, that the form of the curve for 

both locations is practically the same. As the gage heights from the 

chain gage were affected by backwater from the South Fork this gage 

was not replaced.

The conditions at the staff gage above the cable are not favorable 

for refined results. The bed of the stream is of gravel and liable to 

change during freshets.

Ice interferes somewhat with winter records. Ice jams frequently 

form and cause backwater.

Gage heights for this station for 1906, 1907, and 1908 appeared in 

Water-Supply Papers 214, page 103, and 252, page 260.

NOTE. Daily discharges for 1906-7 are based on a rating curve denned by one measurement made in 

1906, and the general form of the 1909 curve. Discharges for January, 1907, estimated because of ice 

conditions.

The daily discharges for 1909 are based on a rating curve well denned between 60 and 800 second-feet. 

Discharges interpolated for days when gage heights were missing. Discharges from Dec. 11 to 31 reduced 10 per cent on account of ice conditions.

MIDDLE FORE OF MALHEUR RIVER BELOW SOUTH FORE, AT RIVERSIDE, OREG.

This station, which is located at the county highway bridge about 

1,000 feet below the mouth of the South Fork of Malheur River at 

Riverside, Oreg., was established December 15, 1908, to determine 

the amount of water flowing through the canyon of Malheur River. 

Gage height observations were not begun until January 16, 1909, as 

it was at first not intended to maintain the station regularly.

The vertical staff gage is attached to the right abutment of the 

bridge from which discharge measurements are made.

Ice interferes somewhat with winter records as at the station above 

the mouth of the South Fork.

As the gage heights are rather uncertain they are withheld until 

more data are obtained. No rating curve has yet been developed.

NORTH FORK OF MALHEUR RIVER NEAR BETTLAH, OREG.

This station, which is located 7 miles below Beulah, Oreg., in sec. 

33, T. 20 S., R. 37 E., was established March 21, 1909. The gage is 

of the chain-and-weight type.

The records represent practically the total run-off of North Fork 

and are of especial value as showing the quantity for storage in the 

Beulah or Agency Valley reservoir site just above.

Measurements are made from a standard cable equipment. The 

right bank is low but is not liable to overflow. The left bank is high 

and rocky. The bed of the stream is composed of gravel and will 

change in ordinary freshets.

PAYETTE RIVER DRAINAGE BASIN. 

DESCRIPTION.

Payette River rises in the eastern part of Boise County, Idaho, and 

flows in a generally westerly direction to its junction with Snake 

River near Payette, Idaho. It is about 110 miles long and drains 

an area comprising approximately 3,565 square miles. Its basin 

is well wooded and mountainous and is similar to that of Boise River.

The principal tributaries of the Payette are its Middle and North 

forks. The low-water flow of the river is appropriated for irrigation 

in the valleys below Horseshoe Bend, but more than a million acrefeet of flood water runs to waste each year. Payette Lake, at the 

head of the North Fork, affords a good storage site, which will be 

used by the United States Reclamation Service.

PAYETTE- RIVER NEAR HORSESHOE BEND, IDAHO.

This station, which was established February 13, 1906, to determine the total amount of water available for irrigation, is located 

on the main river, about 10 miles below the junction of the North 

and South Forks, at a point known as Jerusalem, 5 miles above Horseshoe Bend post office, and about 32 miles from Boise, the most convenient railway point.

There are no tributaries below the station except small creeks, 

which are dry the greater part of the year. Squaw Creek is the 

largest of these. As no water is diverted above the station, the 

records give the total amount of water available from the upper 

Payette basin.

The gage heights are not affected by ice, but some irregularities 

in daily flow are caused by flushing during the logging season. The 

gage datum has remained unchanged.

NORTH FORK OF PAYETTE RIVER DRAINAGE BASIN. 

NORTH FORK OF PAYETTE RIVER AT LARDO, IDAHO.

This station was established August 25, 1908, to determine the 

amount of water available for storage on Big Payette Lake.

On this date a temporary gage was established about If miles 

below the lake outlet and was about the same distance from the 

Lardo post office. This gage was read from September 1 to October 

8, 1908. On October 14, 1908, a permanent vertical staff gage was 

installed on the left bank one-fourth mile below the lake outlet.
NOKTH PACIFIC COAST. 333

A car and cable equipment from which discharge measurements 

are made is located about half a mile below the gage.

LAKE FORK OF PAYETTE RIVER NEAR M'CALL, IDAHO.

This station, which was established September 28, 1909, to determine the amount of water available for a proposed Carey Act project 

on the Lake Fork of Payette River, is located in sec. 13, T. 18 N., 

R. 3 E., at Waini's ranch, about 1 mile below Little Payette Lake 

and about 5 miles from McCall post office.

One small creek enters between this station and the outlet of the 

lake. There are no diversions above, but a small canal heads about 

one-quarter mile below the staff gage.

The gage heights are very little affected by ice and not at all by 

artificial control above, but will at times show the effect of backwater from the dam at the head of the irrigation canal below.

High-water measurements will be made from a cable equipment 

located about 200 feet below the gage. Low-water discharge measurements can be made by wading about one-fourth mile upstream 

from the gage.

A good rating covering the range of 1909 gage heights has been 

obtained.

POWDER RIVER DRAINAGE BASIN. 

DESCRIPTION.

Powder Kiver, which drains the eastern slope of the Blue Mountains, rises in the extreme western portion of Baker County, flows 

east, then north through Baker City to the town of North Powder, 

where it turns abruptly to the southeast and empties into Snake 

River in the east-central part of Baker County.
NOKTH PACIFIC COAST. 337

The general elevation of the headwaters is 6,000 feet above sea 

level, while that of the valley is 3,300 feet. Sumpter is 4,415 feet 

above sea level, and Baker City, 3,586 feet. The only important 

tributary stream is Eagle Creek, which drains the southern part of 

the Powder River Mountains and empties into the Powder near its 

mouth. The total drainage area of Powder River at the mouth is 

1,660 square miles; at Baker City it is 341 square miles.

At" the headwaters the country is mountainous and heavily forested 

and the principal industry is mining and lumbering. The valley of 

the Powder has not been greatly developed, although a number of 

irrigation ditches are in operation. Any extensive development will 

involve the construction of storage reservoirs, for which facilities are 

not lacking.

The mean annual rainfall at Baker City is 15 inches; in the headwater region it is probably twice that amount, the greater part falling 

during the winter in the form of snow. The determination of stream 

flow in this area is rendered somewhat difficult during the whiter, as 

the streams are icebound for weeks at a time.

POWDER RIVER AT SALISBURY, OREG.

This station, which was established -December 20, 1903, is located 

10 miles above Baker City and one-fourth mile below Salisbury, a 

station on the Sumpter Valley Railroad. It is above all important 

diversions for the Powder River valley.

The data are of considerable practical value, as the waters are used 

for mining above the station and for irrigation below. They are also 

of scientific interest, because this drainage area was once quite heavily 

forested, but is being rapidly logged off.

A small ditch diverts .water about one-fourth mile above the gage. 

This ditch carries considerable water during the spring and early 

summer, but its percentage to the flow in the river'is small. The 

observer increases his readings by 0.1 foot to allow for this. On 

October 10, 1909, the ditch carried 0.5 second-foot.

The vertical staff gage is on the left bank, about 40 feet above a 

wagon bridge, from which discharge measurements are made. The 

gage datum has remained unchanged.

The daily discharge of the river is affected somewhat by placer 

mining operations upstream. During the spring and fall the gage 

heights are affected by melting snow from the Blue Mountains, the 

afternoon gage heights being always higher than the morning readings. 

During the winter months the stream frequently remains frozen for 

long periods. Although an attempt has been made to develop rating 

curves for ice conditions, the results have not been very satisfactory.

POWDER RIVER NEAR NORTH POWDER, OREGk

This station, which was established March 9, 1909, is located at the 

dam site in the lower end of Thief Valley, 7 miles east of North Powder, 

Oreg. A large irrigation project is proposed whereby the waters of 

Powder River will be stored above this point and used for the reclamation of approximately 40,000 acres of land.

About 1 mile above the station a temporary dam is constructed 

each year that raises the water to a sufficient height to subirrigate the 

adjoining lands. For this reason the river is under more or less 

artificial control during the extreme low-water period.

The gage, which consists of an inclined law-water section and a 

vertical section, is located in the measuring section at the cable. 

Discharge measurements are made from a standard cable equipment. 

The bed of the stream is of bowlders and gravel and is not likely to 

change except in extreme high water. Both banks are high and will 

not overflow,

EAGLE CREEK NEAR BAKER CITY, OREG.

This station, which is located 700 feet below the confluence of 

West Eagle Creek with Eagle Creek, and about 35 miles northeast 

of Baker City, was established May 20, 1909, by O. C. Finkelnburg, 

who cooperates with the Geological Survey in maintaining the 

station.

The data obtained at this station will be valuable in connection 

with the irrigation of lands in the Powder River valley, into which 

the waters can be diverted.

The gage is a vertical staff, graduated in feet and tenths, on the 

right bank, 5 feet upstream from the measuring section. Discharge 

measurements are made from a suspended footbridge.
342 SURFACE WATER SUPPLY, 1909, PART XII.

The bed of the stream is composed of gravel and cobblestones, 

and is very rough, but is not likely to change except during extreme 

high water. Anchor ice will probably affect the determination of 

winter discharge to a small extent.

GRANDE RONDE RIVER DRAINAGE BASIN. 

DESCRIPTION.

Grande Ronde River drains the eastern slope of the Blue Mountains 

in Oregon and the northern slopes of the Powder River Mountains, 

a comparatively high range that runs at right angles to the Blue 

Mountain Range. The river rises on the divide in the extreme southern portion of Union County, flows in a northeasterly direction and 

empties into Snake River at Zindel, Wash., about 12 miles below 

the Oregon-Washington line. The principal tributaries of the Grande 

Ronde are Joseph Creek, which drains the Chesnimnus National Forest; the Wallowa, which rises in the Powder Mountains and drains 

the Wallowa National Forest; and Catherine Creek, which drains the 

western portion of the Powder. Mountains. The drainage area of 

Grande Ronde River at its mouth is 3,950 square miles. Above the 

mouth of the Wallowa the drainage area is 1,590 square miles.

The topography of this basin is generally rough, the area being 

almost entirely surrounded by mountain ranges which slope gradually to Grande Ronde Valley, a large area of agricultural land 

approximately 2,700 feet above the sea level. The general elevation 

of the Powder and Blue Mountains, from which the river receives its 

water supply, is 8,000 feet.

The drainage area of this river, except in the agricultural valleys, 

is almost entirely forested, a large part being included in the national 

forests. The mean annual rainfall at La Grande is 19 inches, but 

on the headwaters of the stream it is probably 35 inches. The 

greater part of this precipitation occurs during the winter months as 

snow. The river is subject to an annual spring rise, due to the melting of snow in the mountains, and damaging floods are frequently 

caused by the sudden melting of snows by chinook winds.

The agricultural activities have in the past been largely confined 

to the production of wheat, and irrigation has not been extensively 

practiced, although exceptionally good opportunities are afforded. 

Only the lower valley lands immediately contiguous to the streams 

have been irrigated, but there are at present under consideration a 

number of larger projects that involve the construction of reservoirs
344 SURFACE WATER SUPPLY, 1909, PART XII.

and the irrigation of large areas by means of long canals. Records 

of the flow of some of the streams in this basin have been kept since 

1904.

GRANDE RONDE RIVER AT HILGARD, OREG.

This station, which is located at the county highway bridge, onehalf mile below Hilgard station on the Oregon Railroad & Navigation line at the he'ad of Grande Ronde Valley and just below the 

mouth of Five Points Creek, which is the most important tributary 

above the Grande Ronde Valley, was established November 6, 1903, 

to determine the quantity of water available for irrigation.

At this point the river is chiefly used for the transportation of logs, 

and on this account it has been almost impossible to obtain reliable 

records of flow. There are a number of dams on the stream, behind 

which water is impounded and then released in order to carry the 

logs to their destination. Many times logs ground on the bars below 

the station, and even in the cross-section where measurements are 

made, and produce backwater.

The vertical staff gage is fastened to the downstream side of the 

middle pier of the bridge, from which discharge measurements are 

made. The gage datum has remained unchanged.

The following discharge measurement was made by F. F. Henshaw:

October 14, 1909: Width, 37.5 feet; area, 33.4 square feet; gage height, 2.83 feet; 

discharge, 32.3 second-feet.

Daily gage height, in feet, of Grande Ronde River at Hilgard, Oreg.,for 1909.

NOTE. These discharges are based on a rating curve that is not well defined.

Discharges Jan. 1 to 17, reduced 25 per cent and Dec. 19 to 31 reduced 15 per cent from openwater rating, to allow for ice conditions. Other days during the winter months are probably affected 

to a greater or less extent by ice conditions.

346 SURFACE WATER SUPPLY, 1909, PART XII.

GRANDE RONDE RIVER AT ELGIN, OREG.

This station, which was established November 20, 1903, is located 

at the county highway bridge on the road from Elgin to Wallowa, 

Oreg., at the lower end of Grande Ronde Valley. It is within the 

city limits of Elgin, above the mouth of Clarks Creek and below the 

mouth of Indian Creek.

The data collected here have general interest in connection with 

the study of the run-off of this basin and because of the use of the 

waters of the stream and tributaries for irrigation in the Grande 

Ronde Valley.

A chain gage is attached to the upstream side of the bridge. 

Discharge measurements are made from the downstream side. The 

gage datum has remained practically unchanged.

The conditions at the station are not favorable for good results. 

The bed is exceedingly rough, and at high water the current flows at 

a decided angle to the bridge from which gagings are made.

The following discharge measurement was made by F. F. Henshaw:

October 15, 1909: Width, 51 feet; area, 54.3 square feet; gage height, 1.64 feet; 

discharge, 74.1 second-feet. Made by wading, 200 feet above bridge.

Daily gage height, in feet, of Grande Ronde River at Elgin, Oreg., for 1909.

GRANDE RONDE RIVER AT ZINDEL, WASH.

This station was established June 30, 1904. It is located at Zindel 

Ferry, 2 miles above the mouth of the stream, 1£ miles below Joseph 

Creek. The records show the quantity of water contributed to Snake 

River by the Grande Ronde drainage basin.
348 SURFACE WATER SUPPLY, 1909,, PART XII.

The data obtained are of scientific interest in connection with a 

general study of run-off factors from such forested areas as are found 

in the Blue Mountains, and are also of value in determining the value 

of the water powers of the lower Grande Ronde.

An inclined gage is located on the left bank just below the ferry. 

Discharge measurements are made from the ferryboat.

The datum of the gage has not been changed since it was installed. 

The gage-height records are complete, but, owing to the inaccessibility 

of the station, few measurements have been made. The conditions 

at the station are favorable for the construction of a permanent 

rating curve.

No measurements were made in 1909.

Daily gage height, in feet, of Grande Ronde River at Zindel, Wash., for 1909.

WALLOWA RIVER NEAR JOSEPH, OREG.

This station, which was established November 12, 1903, is located 

about 300 feet below the controlling dam at the outlet of Wallowa 

Lake and about 1^ miles above Joseph, Oreg.

The data are of value in connection with irrigation development 

and have scientific interest in connection with the determination of 

run-off from the forested areas of the Powder River Mountains.
NOETH PACIFIC COAST. 349

Four large irrigation ditches divert a large portion of the normal 

flow of the river below the gage, the headgate for the first diversion 

being about 125 feet below the gage. The timber dam at the outlet 

of Wallowa Lake is jointly owned and operated by the managers of 

the irrigation ditches.

The original staff gage was located on Wallowa Lake near its outlet, 

but when the timber regulating dam was constructed it was moved 

July 12, 1905, to a point on the right bank of the river 500 feet downstream and 50 feet above a footbridge, from which the discharge 

measurements are made. From March 31 to July 12, 1905, readings 

were taken on a temporary gage about 100 feet below the dam and 

reduced to the datum of the new staff gage set July 12, 1905. The 

gage heights are subject to regulation by the dam above.

The bed of the river is composed of coarse gravel and bowlders and 

is very rough. Individual discharge measurements can not be made 

with great accuracy, except by taking unusual precautions, but a 

rating curve averaging all the measurements gives fair results.

The following discharge measurement was made by F. F. Henshaw:

October 17, 1909: Width, 27 feet; area, 36.4 square feet; gage height, 2.13 feet; 

discharge, 88.6 second-feet. This measurement was made by wading.

Daily gage height, in feet, of Walloiva River near Joseph, Oreg.,for 1909.

WALLOWA RIVER NEAR ELGIN, OREG.

This station, which was established November 18, 1903, is located 

in Wallowa Canyon, at Minam post office, about 9 miles below the 

lower end of Wallowa Valley, just below .the mouth of Minam River
NORTH PACIFIC COAST. 351

and 12 miles from Elgin, Oreg. It is near Minam station on the extension of the Elgin branch of the Oregon Railroad & Navigation 

Co.'s line.

The data are of interest in connection with the determination of 

run-off factors for areas similar to the Wallowa drainage and will 

be valuable for water-power developments.

The gage is in two sections on the left bank at the site of the old 

bridge which collapsed during October, 1905. Discharge measurements were formerly made here, but from this date until August, 

1906, they were made from a temporary bridge 900 feet upstream. 

The new steel highway bridge, from which measurements are now 

made, is about 1,000 feet upstream from the gage. The location and 

datum of the gage have remained unchanged.

During the winter months ice affects the results to a considerable 

degree. Occasionally ice gorges form below the station which back 

the water above the gage. The flow of the stream is fairly uniform.

The following discharge measurement was made by F. F. Henshaw:

October 16, 1909: Width, 130 feet; area, 230 square.feet; gage height, 2.55 feet; 

discharge, 433 second-feet.

Daily gage height, in feet, of Wallowa River near Elgin, Oreg., for 1909. 

[A. M. Bowell, observer.]

PALOUSE RIVER DRAINAGE BASIN. 

DESCRIPTION.

Palouse River rises in the northern part of Latah County, Idaho, on 

the divide between the Spokane and Snake River drainage basins, 

flows west and then south, and discharges into Snake River in the 

southwest corner of Whitman County, Wash. The drainage area 

comprises 2,310 square miles, and at Winona measures 1,120 square 

miles.

The surface is in general rolling and in some places is rough and 

broken. The average elevation at the headwaters of the stream is 

3,000 feet above sea level; the elevation at Coif ax is 1,974 feet.

The principal tributary of Palouse River is Rock Creek, which 

drains a number of small lakes in the northern part of Whitman 

County, Wash. The agricultural lands consist chiefly of rolling 

table-lands, which are largely utilized for the production of wheat. 

No forests of magnitude are found on the drainage area, and such as 

do exist are of the small black pines near the headwaters of the stream.

The mean annual rainfall is about 20 inches, much of which falls 

during the winter months in the form of snow.

The region is well adapted to irrigation, though the present development in that direction is restricted to the small areas contiguous 

to the streams where irrigation by individual or small company 

ditches is possible. A number of projects have been contemplated, involving the storage of waters from the main stream and its 

tributaries in some of the storage sites which are found in this area. 

These sites are in the form of long canyons, called coulees, usually 

dry. Dams constructed at favorable points in such coulees will 

develop storage reservoirs of considerable capacity, but unfortunately 

the water must be supplied by artificial channels, as the drainage area 

above them is usually insufficient to insure an adequate water supply. 

The soil of the country is well adapted to all kinds of products possible through irrigated agriculture.

PALOTTSE RIVER AT HOOPER, WASH.

This station, which was originally established April 1, 1897, by the 

land department of the Northern Pacific Railway, was taken over by 

the United States Geological Survey September 9, 1897, and reestablished about 1 mile downstream and above the mouth of Cow Creek. 

It is 1 mile from Hooper, Wash., a station on the Oregon Railroad & 

Navigation Co.'s line.

The data obtained at this point are of value as indicating the 

amount of water available for irrigation on the lands of the Washtucna 

Valley and the territory to the north of Pasco. As the low-water 

flow is comparatively small, any development for irrigation must

84547° WSP 272 11 23
354 SURFACE WATER SUPPLY, 1909, PART XII.

involve the construction of storage reservoirs. A number of sites 

were under consideration when the Palouse project was investigated 

by the United States Reclamation Service.

Several gages have been used, all referred to the same datum. The 

present gage is in two sections; an inclined low-water staff and a vertical staff on the right bank at the cable from which discharge measurements are made. The gage datum has remained unchanged. It 

is 1,053.42 feet above sea level.

The conditions at the station are favorable for good results. During 

the winter months there is little or no interference from ice, so that 

continuous records have been possible when gage observers were 

available.

The following discharge measurement was made by G. L. Parker:

October 20, 1909: Width, 60 feet; area, 68 square feet; gage height, 1.01 feet; discharge, 26 second-feet.

Daily gage height, in feet, of Palouse River at Hooper, Wash., for 1909. 

[Mrs. L. C. Huffman, observer.]

WALLA WALLA RIVER DRAINAGE BASIN. 

DESCRIPTION.

Walla Walla River rises on the western slope of the Blue Mountains 

in the southwest portion of Walla Walla County, Wash., and the 

northeastern part of Umatilla County, Oreg., and flows westward into 

Columbia River. Its drainage area lies immediately north of that of 

Umatilla River and is in many respects similar.

Altitudes within the basin range from 5,000 feet on the headwaters 

to 1,000 feet near Walla Walla, and the mean annual rainfall ranges 

from 30 inches in the upper portion to 12 in the lower portion of 

the area. Only the upper part of the drainage area is forested; the 

lower half is given to the production of wheat without irrigation, but 

the lands contiguous to the streams are extensively irrigated.

Climate and soil combine to make the country wonderfully productive, and the agricultural products range from the hardier forage crops 

to fancy fruits.

The headwaters of the stream afford many water-power and storage 

sites which, if developed, would more than double the value of this 

stream. Many times the low-water flow of the river is appropriated 

for irrigation, and the only solution to a situation that has been aggravated in the extreme and promises to become even more critical as 

additional areas are irrigated lies in the construction of storage 

reservoirs.

The conditions for obtaining reliable records of stream flow are not 

good. The river throughout is swift, and the bed is composed of 

gravel that changes with every freshet, thus making a permanent rating impossible. On this account the records are incomplete and usually cover the period between floods. Floods on this stream are 

caused suddenly by chinook winds that melt the snows on the headwaters. Some of these floods have been exceedingly harmful, rendering large areas of fine farm lands worthless and causing great 

damage to life and property.

WALLA WALLA RIVER NEAR MILTON, OREG.

The records for this station begin February 14, 1903, but they are 

not continuous. The station has been located at various points from 

the town of Milton to the Jewel West Bridge, 3 miles above, where a 

station was established August 16, 1906. Owing to lack of observers, 

however, the records are not continuous even at this point. A small 

ditch diverts water from the river just above the station.

The stream bed is composed of coarse gravel, and as the river 

is subject to violent floods a permanent rating curve has not been 

constructed; instead it has been practicable to obtain results only
NOETH PACIFIC COAST. 357

between floods. A number of gages and equipments for gaging have 

been washed away during these excessive floods, and at such a time 

the aspect of the river undergoes a great change.

As a result of a flood which occurred May 30, 1906, new channels 

were formed in many places.

No discharge measurements were made during 1909. The gage was 

read up to July 5, 1909, but as the records are entirely unreliable the 

data are withheld from publication.

SOUTH FORK OF WALLA WALLA RIVER NEAR MILTON, OREG.

This station was originally established February 15, 1903, 1 mile 

above the mouth of the river and 7 miles from Milton, Oreg.

The flood of May 30, 1906, changed the channel of the river and 

left the gage high and dry. On August 10 a new station was established one-fourth mile above the head gate of the Northwest Gas & 

Electric Co.'s pipe line, in the canyon, 12 miles from Milton. It is 

above all diversions for irrigation.

The data obtained at this station are of considerable value in connection with both water power and irrigation, and they also furnish 

some interesting information concerning the run-off from small forested drainage areas under the climatic conditions that obtain in the 

Blue Mountains. The stream is fed by springs and the flow is well 

maintained, although subject to violent floods.

The conditions at this station are not permanent, and a new rating 

curve will be required after each large flood. Since the station was 

established one gage has been washed away and the records interrupted from March 14, 1908, to October 14, 1908, when a new gage 

was installed at the same point and datum as the old. Individual 

measurements can be made with accuracy at low stages. For lowwater conditions the records obtained prior to August 10, 1906, are 

not comparable with those obtained afterwards, because the water is 

largely diverted for irrigation in small ditches before reaching the 

lower station. A considerable portion of this water is undoubtedly 

returned to the stream, and there are also some contributions from 

intermediate drainage.

No discharge measurements were made during 1909. Daily and 

monthly estimates of discharge are withheld until more data have 

been obtained.

TJMATILLA RIVER DRAINAGE BASIN. 

DESCRIPTION.

Umatilla River rises in the northeast corner of Umatilla County, 

Oreg., flows generally westward a distance of 80 miles, and empties 

into Columbia Eiver at the town of Umatilla, Oreg. The drainage 

area above Pendleton spreads out in fan shape, including the western 

slope of the Blue Mountains for a distance of about 70 miles.

The principal tributaries are Birch, McKay, and Meacham creeks. 

The drainage area measures 2,130 square miles at the mouth of the 

river, 640 square miles at Pendleton, and 353 square miles at Gibbon.

The mean annual rainfall ranges from about 30 inches on the summit of the Blue Mountains to 9 inches-at the mouth of the stream, 

being 14 inches at Pendleton and 25 inches at Weston, on the divide 

between Umatilla and Walla Walla rivers. The headwater regions 

of the stream are heavily forested, but downstream the forests give 

place to rolling table-lands devoted to wheat growing. The immediate valley of the river has been irrigated for many years, and the 

entire low-water flow of the stream has been appropriated for irriga-
NOETH PACIFIC COAST. 359

tion. The United States Reclamation Service has completed a project to irrigate about 20,000 acres near Hermiston. The soil of this 

portion of the drainage basin is sandy and the climatic conditions are 

favorable for the production of fruit.

The bed of the river throughout its course is composed of coarse 

gravel, which shifts during the sudden and violent floods, changing 

conditions materially. The river has developed a flood plain from 

100 to 500 feet in width.

UMATILLA EIVEE AT GIBBON, OREG.

This station, which was established July 22, 1896, is located on the 

Umatilla Indian Reservation, 1 mile below Gibbon, Oreg., about 1| 

miles below the mouth of Meacham Creek, and 2 miles above the 

mouth of Squaw Creek.

Records of flow have been kept since 1896; but they have been 

interrupted by destruction of the equipment by floods or through 

the lack of an observer. These records are of particular value to irrigation projects in the lower valley and to water-power development.

Violent floods have already destroyed several gages and cables. 

After each flood the conditions are so altered that it is necessary to 

rerate the station. The maintenance of a permanent gage datum is 

therefore not essential. Owing to the shifting nature of the bed at 

high water, crest discharges can not be determined. Estimates during flood periods have, however, been-made either from facts obtained 

from local authorities or by comparison with the other stations farther downstream whenever it could be done with a reasonable degree 

of accuracy.

UMATILLA RIVER NEAR YOAKUM, OREG.

This station was established May 5, 1903, at the Yoakum highway 

bridge, 1^ miles east of the Yoakum station of the Oregon Railroad 

& Navigation Co. and 18 miles below Pendleton, Oreg.

No tributaries enter in the immediate vicinity of the station, but 

water is diverted for irrigation by a number of ditches both above 

and below, the most important being the Horseshoe ditch, which 

takes water about 1 mile above the gaging site. A number of large 

canals take water from the river at points farther down, the largest 

of these being a supply canal for Cold Springs reservoir, which has 

recently been constructed by the United States Reclamation Service 

for the Umatilla project.

The gage is a split rail spiked to the south abutment of the highway 

bridge, from which discharge measurements are made.

The gage datum has not been changed since the station was established. Conditions are favorable for good results at all stages except 

extreme high water, when the banks of the stream in the vicinity of 

the station overflow and the entire flood plain is covered.

The following discharge measurement was made in 1909 by H. D. 

McGlashan:

March 12, 1909: Width, 76 feet; area, 293 square feet; gage height, 5.20 feet; discharge, 937 second-feet.
362 SURFACE WATER SUPPLY, 1909, PART XII.

Daily gage height, in feet, of Umatilla River near Yoakum, Oreg.,for 1909.

NOTE. These daily discharges are based on a rating curve that is well defined between discharges of 20 

and 7,660 second-feet. Discharges Jan. 10 to 16 reduced 40 per cent; Jan. 17 to 19 interpolated on account 

of ice conditions.

The daily discharges for Jan. 30 to Feb. 21 were obtained from corrected gage heights based on a relation 

curve between this station and that at Gibbon, and are approximate. See footnote to gage heights.

UMATILLA RIVER NEAR UMATILLA, OREG.

This station, which was established October 21, 1903, is located 

about 1^ miles above the mouth of the river, about 1^ miles above 

Umatilla, Oreg., about one-half mile below the diversion dam of the 

Oregon Land & Water Co.'s canal, and one-fourth mile above the 

head gate of the Brownell ditch.

Records at this point show the quantity of water flowing into 

Columbia River after the irrigation requirements have been satisfied.

The gage is on the left bank and is in two sections, both of which 

are sloping and bolted securely into rock. Discharge measurements 

are made from a cable equipment 45 feet above the gage. It is 

equipped with a stay line for flood work.

The natural conditions affecting the flow during open water at this 

station are exceptionally good. The stream bed is nearly flat from 

bank to bank and is free from debris; the bed and banks for a long 

distance above and below the station are on solid rock; the velocity 

of the water is sufficiently swift to prevent the deposition of silt or 

sand, and even at extreme floods the water is all confined within the 

banks of the stream. Sufficient discharge measurements have been 

made to develop an absolutely permanent rating curve covering a 

range of stage from 0 to 11,000 second-feet. Ice is likely to affect 

the discharge considerably during the winter months.

An ice jam took out the lower portion of the inclined gage about 

January 17 or 18, 1909. This was not repaired during the year. 

The observer made his readings by the use of a portion of the gage 

that remained intact, holding it on the same slope. The gage heights 

for 1909 below 3.5 feet are, however, subject to error and the daily 

and monthly estimates, which are based on them, are therefore not 

as good as they should be.

No discharge measurements were made during 1909.

JOHN DAY RIVER DRAINAGE BASIN. 

DESCRIPTION.

John Day River drains the country to the northwest of the Blue 

Mountains. The river rises on the divide between Grant and Baker 

counties, Oreg., flows westward and then northward, and joins Columbia River about 28 miles above The Dalles. Its principal tributaries 

are the North, Middle, and South forks. Its total drainage area is 

7,800 square miles.

The general elevation of its headwaters is about 6,000 feet above 

sea level; at Fossil the elevation is 1,500 feet. The headwater region 

of the stream is forested. Except wheat, which is grown on the rolling uplands by the "dry farming" process, no agricultural products 

of consequence can be raised without irrigation, and as the areas 

which admit of easy irrigation are confined to the immediate valleys 

of the streams, comparatively little has been done in this direction. 

A number of projects are, however, contemplated, under which, by 

means of storage reservoirs and high-line canals, enormous areas of 

very productive table-lands would be developed. The storage facilities are ample for this purpose. It is not likely that extensive development will be undertaken until more detailed studies of flow have 

been made.

The mean annual rainfall varies from 24 inches on the headwaters 

to 10 inches at the mouth. The winters are cold, and the streams are 

frequently icebound throughout the greater part of the winter.

JOHN DAY RIVER NEAR DAYVILLE, OREG.

This station, which is located at a private wagon bridge on K. F. 

MacRae's ranch, 3 miles above Dayville, Oreg., and 3 miles above 

the mouth of the South Fork of John Day River, was established 

November 23, 1908, to obtain data for the study of the possibilities 

of irrigation from this stream by means of storage, as a number of 

excellent reservoir sites are found dn the river above this point.

The vertical staff gage is bolted to the center pier of the bridge 

from which discharge measurements are made.

JOHN DAY RIVER AT M; DONALD, OREG.

This station, which is located at McDonald Ferry and post office, 

16 miles above the mouth of the stream, and one-half mile below 

the mouth of Rock Creek, was established December 16, 1904, to 

determine the amount of water available for irrigation and waterpower development. Storage reservoirs must, however, be constructed to equalize the flow of the stream, which in its natural condition is subject to wide fluctuations. The winter gage heights are 

sometimes affected for short periods by ice.

The general conditions at the station are exceptionally favorable, 

and what appears to be an absolutely permanent rating curve has 

been established.

An inclined gage is bolted to bridge timbers on the left bank 180 

feet upstream from the cable from which discharge measurements 

are made. The datum of the gage has not been changed. The 

observations of gage height are exceptionally good, and the discharge 

data are reliable. No discharge measurements were made during 

1909.

Daily gage height, in feet, of John Day River at McDonald, Oreg., for 1909. 

[Win. Murray, observer.]

SOUTH FORK OF JOHN DAY RIVER AT DAYVILLE, OREG.

This station was established November 21, 1908. It is located onehalf mile above Dayville and 1 mile above the mouth of the stream. 

The Dayville ditch diverts water about one-fourth mile above the 

station, and the flow in the ditch should be included in that of the 

main river to determine the natural flow at this point.

The vertical staff gage is fastened to an alder on the left bank about 

10 feet above the cable, from which discharge measurements are made.

The data obtained will be of value in determining the amount of 

water available for irrigation, as facilities for storing a large portion of 

the annual flow 'are afforded above this point.

DESCHUTES RIVER DRAINAGE BASIN. 

DESCRIPTION.

. Deschutes River has its source in a number of mountain lakes at 

the summit of the Cascade Range just east of the waters of Willamette River in Klamath and Crook counties, Oreg. Its course is 

northward to Columbia River, which it enters about 15 miles above 

The Dalles.

The principal tributaries of Deschutes River are White, Warm 

Springs, Metolius, and Crooked rivers, and the West Fork of the 

Deschutes. All except Crooked River drain the eastern slope of 

the Cascades and contribute the larger portion of the stream flow.
NOETH PACIFIC COAST. 373

The entire drainage area of the system is 9,180 square miles, distributed as follows:

Area of Deschutes River drainage basin.

Square miles.

Deschutes at Bend............................................. 1,530

Deschutes above the mouth of Crooked River................... 2,520

Deschutes at Sherar Bridge.................................... 8, 750

Deschutes River above Lava post office (locally known as Little 

River)...................................................... 720

Crooked River................................................. 2,920

East Fork of Deschutes River.................................. 200

West Fork of Deschutes River.................................. 500

Topographically the area is rough and mountainous. The agricultural lands consist largely of high table-lands cut by deep canyons 

through which the rivers flow, and small arable areas which border 

the streams. The soil is a coarse disintegrated lava. The rocks of 

the entire area are volcanic and so peculiarly porous that the basin 

acts like a huge sponge in the matter of ground storage. Deschutes 

River has perhaps the most remarkable uniform flow of any river 

comparable with it in size, and its economic value is almost incalculable. At the mouth of the stream the maximum flow is six times 

and at Bend only three times the minimum. Ocular evidence of this 

uniformity of flow is presented by the low grass-grown banks between 

which the river flows throughout its upper portions.

The general elevation of the lands around Bend is 3,600 feet above 

sea level; that of the summit of the Cascade Mountains is from 5,000 

to 6,000 feet. Prineville is 2,868 feet above sea level, and Paulina, 

near the upper portion of the Crooked River drainage basin, 3,684 feet.

The timbered portion of this drainage basin is found on the eastern 

slope of the Cascades and on the headwaters of Crooked River.

The annual rainfall varies from 100 inches on the summit of the 

Cascade Mountains to 10 inches along the main course of the stream. 

At Prineville the mean annual rainfall is 9 inches; at Warm Springs, 

11 inches; at Bend, 15 inches. On the headwaters of Crooked 

River the precipitation is probably 20 inches or more.

Although the winter temperatures are low, ice does not affect the 

determination of stream flow to any extent. This is due to the fact 

that the waters reach the river in the form of springs. The high 

stages usually occur in July as the result of the melting of snows in 

the mountains, although occasionally floods are caused by chinook 

winds in the early spring or late fall.

It has been estimated that Deschutes River alone from Bend to 

the mouth, a distance of 140 miles, is capable of furnishing over a 

million horsepower. Power plants need fear neither shortage of 

water during the summer months nor damage from flood. During 

the low-water period, throughout the lower 130 miles of the river's
374 SURFACE WATER SUPPLY, 1909, PART XII.

course, it flows in a narrow canyon with an average fall of about 20 

feet to the mile, and conditions are such that a succession of dams 

could be built almost through its entire length. (See PL VIII.)

DESCHUTES RIVER AT ALLEN's RANCH, NEAR LAVA, OREG.1

This station was established February 17, 1905, on C. B. Alien's 

ranch, about 1 mile north of Lava, Oreg., in the SW. ^ SW. £ sec. 8, 

T. 20 S., R. 11 E. It is half a mile above the mouth of the West 

Fork of Deschutes River. The data obtained here are particularly 

valuable in connection with irrigation development.

The inclined staff gage is on the east bank of the river, about 50 

feet above the cable from which discharge measurements are made. 

The gage datum has not been changed, but the records are not as 

accurate as they should be, owing to a troublesome growth of weeds 

that appears in the river in the vicinity of the station during the 

summer months. As the season advances these weeds greatly retard 

the flow and cause backwater at the gage. Ice is likely to somewhat 

affect the discharge during December, January, and February.

The following discharge measurement was made by R. B. Post:

April 22, 1909: Width, 69 feet; area, 227 square feet; gage height, 7.08 feet; discharge, 432 second-feet.

Daily gage height, in feet, of Deschutes River at Alien's ranch, near Lava, Oreg., for 1909.

876 SURFACE WATER SUPPLY, 1909, PART XII.

DESCHUTES RIVER AT WEST'8 RANCH, NEAR LAVA, OREG.

This station was established June 20, 1906, at a private bridge on 

B. F. West's ranch, about 2 miles north of Lava, Oreg., and 18 miles 

above Bend, Oreg. It is just below the mouth of Spring River and 

about 1J miles below the mouth of West Fork of Deschutes River.

This station affords exceptionally favorable conditions and the 

results are above the average in accuracy. It is located above all 

present diversions from the stream and furnishes the requisite data 

for determining the quantity of water available for irrigation of lands 

in the Deschutes Valley. At present two large canals are operated 

under the provisions of the Carey Act by the Deschutes Irrigation & 

Power Co. The complete reclamation of all land segregated under 

this law contiguous to Deschutes River will bring the total to 360,000 

acres under irrigation.

The staff gage first used at this station was spiked to the right 

approach of the bridge. A new vertical staff gage was set April 10, 

1907, in the same section but 2 feet riverward at the same datum. 

The datum of these gages has not been changed since the station was 

established. Discharge measurements are made from the bridge.

The river at this point never freezes, as it is entirely spring fed, and 

although it is used for logging its channel is deep and the current swift 

and gage heights are not affected. On February 20, 1909, the observer moved away and the records will be interrupted until another 

can be secured. The interval can, however, be filled from the Benham Falls station.

DESCHUTES RIVER AT BENHAM FALLS, OREG.

This station, which is located 700 feet above Benham Falls, about 

14 miles above Bend, Oreg., and above the intake of an irrigation 

canal under construction at this point, was established April 1, 1909, 

and is maintained in cooperation with the Deschutes Irrigation & 

Power Co.

On July 29, 1909, a cable was installed for making discharge measurements and a staff gage placed on the right bank near the cable. 

Better conditions were found at this point than obtained at the 

section of the lower gage installed by the Deschutes Irrigation & 

Power Co., which reads 3.35 feet lower than the United States Geological Survey gage.

The banks of the stream in the vicinity of the cable are low, but 

are not subject to overflow. The channel is straight and the bed of 

the stream is of sand and gravel. Weeds grow along each bank and 

may interfere somewhat with the determination of discharge in the 

summer months.

The results at this station are comparable with those formerly 

obtained at West's ranch, about 4 miles upstream from this point.
378 SURFACE WATER SUPPLY, 1909, PART XII.

The following discharge measurement was made by R. B. Post:

July 30, 1909: Width, 137 feet; area, 969 square feet; gage height, 4 feet; discharge, 

1,560 second-feet.

Daily gage height, in feet, of Deschutes River at Benham Falls, Oreg.,for 1909.

NOTE. Discharges at West's ranch used Jan. 1 to Feb. 20; discharges at Bend used Feb. 21 to Mar. 29. 

Owing to the method of determining the monthly estimates for January, February, and March, the means 

for these months can not be considered as accurate as the following months.

DESCHUTES KIVER AT BEND, OREG.

A station was established at Sizemore's bridge, near Bend, December 22, 1904, and data were published for 1905 and 1906, but the 

conditions were not favorable for accurate results, as the channel at 

this point is comparatively shallow and exceedingly rough and the 

gage heights are influenced by back water from saw logs impounded 

at a mill below the station, and the data for these years are therefore 

not reliable.

On March 30, 1907, gage records were suspended at this point and 

on April 23, 1907, the station was reestablished at Statt's bridge, in 

Bend, Oreg. A gage was bolted to a bowlder near the pumping 

plant.
380 SURFACE WATER SUPPLY, 1909, PART XII.

The gage heights at this location are not artificially influenced, but 

there are no facilities for making accurate measurements. The 

records of gage heights are furnished without cost to the Survey by 

Mr. C. A. Stanborough, engineer of the city pumping plant. As the 

discharge of the river at this point is of general interest in the study 

of the river system, a rating has been developed by comparison with 

stations on the river and canals above.

The following discharge measurement was made by R. B. Post:

December 18, 1909: Width, 99 feet; area, 789 square feet; gage height, 1.89 feet; 

discharge, 2,010 second-feet.

Daily gage height, in feet, of Deschiites River at Bend, Oreg.,for 1909.

involved in determining these estimates the accuracy of the monthly means can not be considered better 

than fair.

DESCHUTES RIVER AT LAIDLAW, OREG.

This station was established January 1, 1909, at the old Laidlaw 

highway bridge in Laidlaw, Oreg. It is below all important diversions for irrigation. A short distance below the station the river 

enters a canyon which it follows to its mouth.

The vertical staff gage is attached to piling on the highway 

bridge. Discharge measurements are made from the new county 

bridge 1 mile upstream from the gage. As no observer was available
382 SURFACE WATEE SUPPLY, 1909,, PART XII.

at the upper bridge location, it was found necessary to locate the 

gage at the lower bridge, where measuring conditions are not good. 

At the measuring section the right bank is low, but is not liable to 

overflow. The left bank is high and rocky, more or less covered with 

brush and willows. The bed of the stream is composed of gravel 

and is fairly permanent.

Below Laidlaw the stream is essentially a power stream, and above 

the conditions are favorable for diversion of water into irrigation 

canals.

NOTE. Discharges Jan. 1 to Nov. 30 were obtained from a rating curve which is not well defined; 

Dec. 4 to 26 from a curve which is well defined between 1,400 and 2,090 second-feet. Discharges for days 

for which there are no gage heights were estimated from a hydrograph comparison with the flow at Bend 

except for Dec. 1 to 3, which were interpolated.

DESCHUTES RIVER NEAR BIGGS, OREG.

This station was first established October 19, 1897, at the Free 

Bridge and known as "Deschutes River near Moro." It was discontinued December 31, 1899, and reestablished July 7, 1906, at
384 SURFACE WATER SUPPLY, 1909, PART XII.

Taylor's ranch, near Biggs post office, Oreg., 1^ miles above the 

mouth of the river, about the same distance above the Oregon Railroad & Navigation Co.'s bridge, and about 1 mile above Moody's 

toll bridge. The river at this point runs in a deep canyon and there 

are no tributaries for several miles upstream. The water at this 

point is at present used only for an insignificant amount of irrigation. 

The records at this station are directly comparable with those 

obtained at the Free Bridge near Moro from 1897 to 1899, although 

conditions at the the earlier station are not nearly so favorable for 

accurate results as are those at the present location.

The staff gage is in two sections on the right bank, about 450 feet 

below the cable from which discharge measurements are made. The 

upper section of the gage is vertical and located near the inclined 

low-water section.

No discharge measurements were made during 1909. The station 

was last inspected October 10, 1908, and conditions of flow are 

believed to be unchanged. The accuracy of the daily and monthly 

discharges given below is dependent upon the permanency of conditions of flow and the elevations of the gage since that date.

Daily gage height, in feet, of Deschutes River near Biggs, Oreg., for 1909. 

[Wilbur Taylor, observer.]

WEST FORK OF DESCHUTES RIVER NEAR LAVA, OREG.1

This station was established February 26, 1905, on the ranch of 

Joseph Whitfield, in the NE. i NE. £, sec. 24, T. 20 S., R. 10 E., 1£ 

miles west of Lava, Oreg., and about the same distance above the

junction of West Fork with Deschutes River. It was discontinued 

March 31, 1907, and reestablished at the same place April 23, 1909. 

A discharge measurement was made, however, on March 28, 1908. 

See Water-Supply Paper 252, page 318.

The inclined staff gage is located on the right bank above the cable 

from which discharge measurements are made.

Ice affects the flow past the station during the winter to some 

extent. In the summer a growth of weeds in the river bed causes 

backwater conditions at the gage.

The station furnishes data of considerable economic value, as the 

waters of the stream will be largely used for irrigation. Some exceptional storage sites are found in the headwaters of the river.

TUMALO CREEK DRAINAGE BASIN. 

DESCRIPTION.

Tumalo Creek rises on Ball Butte in the southwestern part of 

Crook County, Oreg., and flows in a general easterly course to its 

junction with Deschutes River, about 4 miles south of Laidlaw.
388 SURFACE WATER SUPPLY, 1909, PART XII.

The Columbia Southern Irrigation Co. selected about 27,000 

acres of land for development under the terms of the Carey Act. 

Land with water rights was sold to settlers, and construction of 

canals was begun before any knowledge was obtained of the flow of 

the stream. Later it was found that the water was not sufficient 

for more than about one-third of the land and considerable litigation 

followed.

TUMALO CREEK NEAR LAIDLAW, OREG.

This station was-first established May 15, 1906, one-half mile 

above the head gate of the Columbia Southern canal in «ec. 2, T. 

18 S., R. 10 E. At this point records were obtained during the irrigation season only, observations being furnished by the patrolman 

in the employ of the irrigation company. During the winter no 

patrolman was kept at the head gates, and a substitute station was 

kept at a bridge on the Bend-Sisters Road, 6 miles downstream. As 

first located the station was below the intake of the Wimer canal 

and during the period from May 15, 1906, to April 1, 1908, the flow 

in Wimer canal should be added to that in Tumalo Creek to obtain 

the natural flow at this point. On the latter date, however, the 

Tumalo Creek station was moved to a point 1^ miles above the intake 

of the Columbia Southern canal and 300 feet above the Wimer 

canal.1 Gages at the new station are not comparable with those at 

the old. During 1909 arrangements were made whereby winter 

records were secured.

The records of gage height are furnished without cost to the Survey 

by the Columbia Southern Irrigation Co.

LEWIS CREEK NEAR LAIDLAW, OREG.

Lewis Creek is a mountain stream about 1J miles long that rises 

in Lewis Lake, a small lake in the Cascade Range, and enters Tumalo 

Creek 2 miles above the intake of the Columbia Southern canal.

The station was established April 2, 1908, at the trail crossing near 

the mouth of the creek near Laidlaw, Oreg. The vertical staff gage 

is on the left bank about 6 feet above the trail crossing. Discharge 

measurements are made from a small foot log.

The data will be valuable in the study of possible storage development in the basin of Tumalo Creek.

No discharge measurements were made during 1909.

SQUAW CREEK AND M ALLISTER S DITCH NEAR SISTERS, OREG.

Squaw Creek rises in the Cascade Range in the southwestern part 

of Crook County, Oreg., and flows northeastward to its junction with 

Deschutes River. Its waters are used extensively for irrigation in 

small ditches. Segregations of large areas of land have been made 

for reclamation under the provisions of the Carey Act to be irrigated 

from this creek. 

The station on Squaw Creek was established June 15, 1906. It is 

located 4 miles south of Sisters and above all present ditches except
NORTH PACIFIC COAST. 391

McAllister's ditch. McAllister's ditch heads a short distance above 

the station, and the amount diverted in 'this ditch should be added 

to that measured in the creek in order to determine the natural flow 

of the stream at this point. The vertical staff gage on the creek is 

located on the right bank about 3 feet above a foot log used in making 

discharge measurements. The station on the ditch is located just 

above the wasteway gate. Measurements are made from cross timbers 

on the upstream side of this wasteway.

A short distance below the station a temporary brush dam is constructed each year to divert water into McAllister's ditch. This is 

altered, by freshets and washed away in the fall. On this account 

the records of flow are not as reliable as could be desired.

The following discharge measurement was made by R. B. Post:

May 29, 1909: Width, 7.7 feet; area, 12.9 square feet; gage height, 1.60 feet; discharge, 17.4 second-feet.

CROOKED RIVER DRAINAGE BASIN. 

DESCRIPTION.

Crooked Kiver, the principal tributary of Deschutes Kiver from 

the east, rises in the Blue Mountains in the eastern part of Crook 

County, Oreg., is about 125 miles long, and drains a total area of 

about 2,920 square miles. The principal tributaries are Bear, Beaver, 

and Ochoco creeks.

The river flows through a narrow valley, in some places a mere 

gorge and in others opening out to a width of more than a mile. 

The topography of the basin is varied and picturesque. For about 

25 miles above the mouth the contiguous table land is rolling and 

is covered with a sparse growth of juniper. Above this point the 

surface is more broken, and low hills rise rapidly to lofty mountains covered with a heavy growth of pine timber. The prominent 

topographic features are the abrupt rim rocks along the watercourses 

and the deeply eroded sides of the mountains that rise above the 

lava flow. Altitudes range from 2,500 feet to 6,000 feet above sea 

level. The principal rocks of the region are basaltic lava, sandstone, 

and allied sedimentary rocks and some dikes of a porphyritic material, 

and these rocks disintegrated make up the soil.

Approximately 20 per cent of the drainage area is forested with 

pine timber. The annual rainfall at Prineville is about 9 inches, but 

it is much greater in the higher altitudes. As this precipitation is 

well distributed throughout the year some crops can be raised without irrigation, but no successful general agriculture is possible without irrigation.

Although nearly the entire flow of the stream is used for irrigation 

during the irrigating season, no effort has been made to store the flood
394 SURFACE WATER SUPPLY, 1909, PART XII.

water of the river in order to increase the summer flow. In addition 

to the reservoir site at Stewart's grade, about 12 miles above Post, 

there are many other places along the river where dams could be constructed and water stored for irrigation and power development, the 

most important site being at Summit Prairie, on the North Fork.

CROOKED RIVER NEAR POST, OREG.

This station was established November 9, 1908, at Stewart's grade, 

in the deep canyon 12 miles above Post and 6^ miles below the mouth 

of North Fork of Crooked River, at a proposed site for a dam that will 

impound a large amount of water for irrigation. It is about half a 

mile below the junction of the North Fork of Crooked River.

The staff gage is on the right bank at the cable from which discharge measurements are made. On October 22, 1909, the gage 

datum was lowered 1 foot and all 1909 readings corrected to the 

new datum. The gage heights for 1908, published in Water-Supply 

Paper 252, page 327, should be increased 1 foot to be comparable 

with the 1909 gage heights.

NOTE. These daily discharges for 1908-9, except as noted, are based on a rating curve fairly well defined 

between 40 and 1,400 second-feet.

The gage heights for 1908 were increased 1 foot before applying the rating table. See description.

Discharges Nov. 27 to Dec. 2, 1908, interpolated; Dec. 15 to 31, 1908, reduced 10 per cent; Jan. 1 to 15, 

1909, reduced 20 per cent; Jan. 17 and 18, interpolated; Jan. 28 to Feb. 12, reduced 25 per cent; Dec. 3 to 

27, 1909, reduced 60 per cent; and Dec. 28 to 31, reduced 20 per cent to allow for ice conditions.

OCHOCO CREEK AND ELLIOTT DITCH NEAR PRINEVILLE, OREG.

The station on Ochoco Creek was established October 29, 1908, 

at Elliott's ranch, 6 miles east of Prineville, Oreg., in the NE. | sec. 5, 

T. 15 S., R. 17 E., on the dam site for a reservoir proposed in connection with the development of the Ochoco irrigation project by the 

United States Reclamation Service.

The vertical staff gage is fastened to an alder on the left bank just 

above the cable from which discharge measurements are made. The 

gage datum was lowered 0.75 foot July 15, 1909, and all 1909 readings 

corrected to the new datum. The gage heights in 1908, published 

in Water-Supply Paper No. 252, page 329, should be increased 0.75 

foot to be comparable with the 1909 gage heights.

The Elliott Ditch diverts water from the left bank of the creek 

about 1,000 feet above the gaging station. Records are kept on the 

flow in the ditch in order to determine the natural flow of the creek. 

The vertical staff gage is installed in the ditch about 150 feet upstream 

from the creek gage. Discharge measurements are made from a 

foot plank.

NOTE. The gage heights for 1908 were increased 0.75 foot before applying the rating table. See 

description.

The discharges for 1909 were obtained from a rating curve which is fairly well defined below discharge of 

200 second-feet. Discharges Dec. 27, 1908, to Jan. 14, 1909, estimated on account of ice conditions. Discharge Dec. 20 to 24, 1908, estimated to average 15 second-feet per day. Discharges interpolated for all 

other days when gage was not read.

METOLIUS RIVER NEAR SISTERS, OREG.

This station was established October 31, 1908, at Rigg's ranch, 

7 miles above the mouth of the stream and 26 miles northeast of 

Sisters, in sec. 28, T. 11 S., R. 11 E. A vertical staff gage is located 

about 50 feet upstream from the cable from which discharge measurements are made.

The results obtained here will be particularly valuable for waterpower development and in making a general study of run-off conditions in the Deschutes River system. The stream throughout its 

course runs in a deep canyon and is entirely spring fed. The flow is 

well maintained throughout the year.

404 SURFACE WATER SUPPLY, 1909, PART XII.

CANALS AND DITCHES IN DESCHUTES RIVER BASIN. 

CENTRAL OREGON AND PILOT BUTTE CANALS NEAR BEND, OREG.

The Central Oregon and Pilot Butte canals have a common head 

gate where water is diverted from Deschutes River, 3 miles above 

the town of Bend. They are operated for the reclamation of a large 

area of land segregated under the provisions of the Carey act by the 

Deschutes Irrigation & Power Co., by whom the gage-height records 

are furnished without cost to the Survey. The data obtained are 

valuable in a study of the hydrographic features of the Deschutes 

River system.

The station on the Central Oregon canal was established March 11, 

1905. Measurements are made in a flume.

The station on the Pilot Butte canal was established March 6, 

1905, half a mile below the wasteway and 1 mile below the point 

where the water diverted from Deschutes River is divided into the 

two canals. The measurements are made in an earth section and 

small changes in the channel have operated to diminish the accuracy 

of the results over what would have been obtained under stable 

channel conditions.

The water is turned out of these canals in freezing weather.

.No discharge measurements were made on Pilot Butte canal 

during 1909.

The following discharge measurement was made by R. B. Post:

April 22, 1909: Width, 13 feet; area, 27.3 square feet; gage height, 2.10 feet; discharge, 144 second-feet.

Daily gage height, in feet, of Central Oregon canal near Bend, Oreg.,for 1909.

[Deschutes Irrigation & Power Co., observer.]

WIMER CANAL NEAR LAID LAW, OREG.

The Wimer canal diverts water from Tumalo creek about threefourths of a mile above the head gate of the Columbia Southern canal. 

The station was established June 16, 1906, just below the head gate of 

the canal and above the wasteway. It is maintained during the 

irrigation season only. The quantities shown during 1906-7 represent the amount diverted from the river. A part of this was returned 

through the wasteway which enters Tumalo Creek above the head 

gate of the Columbia Southern canal. On April 1, 1908, the station 

was moved to a point below the wasteway, and the records for that 

year show the net amount diverted for irrigation. The water is 

turned out of the canal during freezing weather.

COLUMBIA SOUTHERN CANAL NEAR LAIDLAW, OREG.

This station was established May 15, 1906. It is located in a 

flume 200 yards below the head gate of the canal. The canal was 

constructed, by the Columbia Southern Irrigation Co. for the irrigation of about 27,000 acres of land to be reclaimed under the provisions of the Carey Act. The records of gage heights are furnished 

without cost to the Survey by the company.

The results obtained are of great value to the State, the company, 

and to the settlers on the project. The conditions are favorable 

for good results and the data so far obtained are reliable. The 

station is maintained during the irrigating season only.

The water is turned out of the canal during freezing weather.

KLICKITAT RIVER DRAINAGE BASIN. 

DESCRIPTION.

Klickitat River drains the eastern slope of the southern portion 

of the Cascade Range in Washington. Its position is similar to that 

of Deschutes River in Oregon, except that the two streams flow in 

opposite directions. Both empty into Columbia River a short distance east of the divide.

Klickitat River rises in Goat Mountain, at an elevation of 8,500 

feet above the sea, flows generally southward, paralleling the main 

range of the Cascades, and empties into Columbia River near the 

town of Lyle. The total length of the main stream is 105 miles. 

The principal tributaries, named in their order downstream, are, from 

the west, McCreedy Creek, West Fork, Cunningham Creek, Big 

Muddy River, Bacon Creek, and Outlet Creek; from the east, Diamond Fork,1 Piscoe Creek, Surveyors Creek, White Creek, Little 

Klickitat River, and Swale Creek. The total drainage area is 1,160 

square miles, distributed as follows:

The most prominent feature of the area is Mount Adams, which 

crowns the summit of the divide at an elevation of 12,307 feet. The 

glaciers on this peak cover 2,300 acres. Those to the east supply 

the water in Big Muddy River and Little Muddy Creek during the 

summer months.

The region has been the scene of' pronounced volcanic activity 

and its general topography is in consequence abrupt and rugged. 

The streams as a rule flow in deep canyons cut into the. basalt and 

lavas. Near the summit of the divide and the spurs that extend 

from it are a number of grassy meadows bordered by low benches of 

level or gently rolling land. Many of the meadows are swampy during 

wet seasons, and lakes occupy the deeper depressions. From the 

summit of the range eastward the steep slopes of the mountains give 

way to high, rolling table-lands, into which the streams have cut

River, the largest eastern tributary.

deeply. The canyon walls are very steep and angular and in places 

2,000 feet high, For the most part the rivers occupy the entire 

floors of the canyons, although on the inside of bends there is usually 

a flood plain 100 to 500 feet in width.

The soil of the area has resulted from the disintegration of the 

lavas and basalts. Some of the lavas are very porous, having the 

appearance of sponge, and in places considerable scoria and pumice 

are found. The rocks produce a coarse, porous soil that absorbs large 

quantities of water and readily delivers it to the ground rocks. Thus 

the ground-storage capacity of the area is relatively high. The result 

is that the streams have a fairly uniform flow and maintain a good 

discharge during the summer months. This natural tendency is 

further augmented by additional waters supplied by the glaciers on 

Mount Adams and the snow banks that stand in favored spots well 

into the summer.

The entire area, except the extreme eastern portion, is more or less 

covered with timber. On the west side of the river the growth is 

heavy, but it gradually thins out toward the eastern boundary of the 

basin. Only 4 per cent of the total area lies within the Columbia 

National Forest. In this portion about 80 per cent is heavily timbered and 18 per cent has been burned over. Of the entire area about 

75 per cent is timbered, but the stand on over half of this is less than 

2,000 feet board measure per acre. In the national forest about 55 

per cent of the timber is yellow pine. Red or yellow fir constitutes 

20 per cent of the stand, tamarack 10 per cent, white pine 5 per cent, 

mountain hemlock 5 per cent, and all other species 5 per cent. Over 

the entire area yellow pine is the predominating species. The sides 

and bottoms of the canyons are studded with patches of scrub oak 

in the lower portions, and cottonwoods and alders grow profusely 

near the water's edge.

Only a small part of the land suitable for agriculture is cultivated. 

In the vicinity of Glenwood an important amount of hay is cut from 

the moist table-lands. Irrigation is practiced to some extent on these 

lands. Hay and the hardier vegetables constitute the principal crops. 

Wheat is raised in considerable quantities on the high lands in the 

eastern portion of the drainage area. Irrigation is practiced also on 

the lower stretches of the river, but the irrigated tracts are small and 

lie in narrow strips along the river bank in the bottom of the canyon. 

About 3 miles below Little Klickitat there is a garden and strawberry 

patch of about 3 acres, which produces abundantly under irrigation.

The only railroad in the area is the Goldendale branch of the Spokane, Portland & Seattle Railway (the "north bank" route). This 

branch runs from Lyle, on the main line, to Goldendale, near the 

southeastern border of the State. It follows the river canyon for 17 

miles, crossing the river twice in that distance. It leaves the river a

short distance above Klickitat and follows Swale Creek Canyon to the 

uplands. A county road from Goldendale to Glenwood crosses the 

river near the mouth of Dead Canyon. Between Klickitat and Parrotts Bridge the canyon is without trails and is well-nigh impassable. 

From Parrotts Bridge to the source a trail follows the river or the 

bench lands bordering it. There are also trails along the ridges, but 

they are almost impassable during the winter months except on 

snowshoes.

There are a number of mineral springs in the area. Eest Soda 

Springs is a famous camping resort to which a road has been- built 

down the canyon from the Goldendale-Glenwood road. A ferry was 

also installed by popular subscription. The soda springs below West 

Fork furnish an abundance of mineral water fully equal to the water 

of the famous Shasta Springs in California. Below McCormick 

Meadows is another soda spring of excellent quality. The water 

issues from seams in the bedrock.

So far as known the area contains no very large reservoir sites. 

Many small ones, however, could be developed in the swamps and 

lakes of the upland benches. The best sites are found on Fish Lake 

Stream, a tributary of West Fork. Fish Lake, Howard Lake, and 

Two Lakes could probably be developed to a moderate extent. The 

grade of Fish Lake Stream is comparatively flat and detailed investigation would probably discover good storage sites. Near the headwaters of Hellroaring Creek there is a favorable site for storage. The 

waters of this stream are largely supplied from Mazama Glacier. 

About a mile below the glacier the stream spreads in two branches 

through a comparatively flat meadow. The south branch has a 

good dam site at the east end of the meadow, where a dam 100 feet 

high could be constructed. The north branch falls over the escarpment, dropping over 200 feet in one-fourth mile. It is likely that 

considerable storage could be developed at McCormick Meadows on 

the main stream, 5 miles by trail above the mouth of Diamond Fork. 

There is little doubt that all these1 reservoirs would be filled every 

season.

On account of the fairly steep grade, well-maintained flow, and 

rocky canyons through which Klickitat Eiver and its tributaries 

flow, the system offers some exceptionally favorable opportunities for 

power development. At present, however, there are no such developments in the drainage area, although several water filings have been 

made for power and irrigation.

West Fork and Big Muddy River offer some favorable opportunities for high-head developments. The streams flowing directly from 

Mount Adams, are almost literally "on end," and there are numerous falls which could readily be utilized for power development. 

Below the mouth of Hellroaring Creek, Big Muddy River enters a
NORTH PACIFIC COAST. 413

box canyon, in places not over 6 feet wide, cut into the basalt. 

The total fall in the last 3| miles is 968 feet. Above the mouth of 

Hellroaring Creek this stream falls 1,300 feet in 4 miles over large 

bowlders that fill the river bed. The bed of Hellroarmg Creek is 

similarly strewn with bowlders, and the waters fall nearly 2,000 feet 

in 51 miles. One-half mile above the mouth of West Fork there 

are falls 15 feet in height. Another drop of about the same height 

occurs three-fourths of a mile below the mouth of Little Muddy Creek 

and there are several falls on Fish Lake Stream, a short distance 

above its mouth. The grade of the main Klickitat is fairly uniform, 

averaging 44.5 feet "to the mile for the 73 miles surveyed. The fall 

gradually decreases from 63 feet to the mile below Diamond Fork 

to 20 feet to the mile at the head of the box canyon. This box 

canyon continues from a point about half a mile above the lower 

railroad bridge to the mouth of the river, but the lower 1^ miles are 

subject to backwater from Columbia River. The canyon has been 

cut in the solid basalt, and in places is not over 10 feet in width, 

with perpendicular sides of jagged rock. The total fall here is 75 

feet in three-fourths of a mile. Favorable sites for dams are numerous on the main stream, and the benches along the river in some 

places render construction of open canals entirely feasible. On the 

steep canyon sides, however, water would be more safely carried in 

large pressure pipes. During warm weather the waters, particularly those from Mount Adams, carry considerable glacial silt which 

would cut machinery badly.

During the summer of 1909 the United States Geological Survey 

made a water-power survey of this basin.1 Discharge measurements 

were made on all important tributaries and of the main river at 

various points. The stream-flow data obtained during this investigation are included in the present report.

KLICKITAT RIVER ABOVE AND BELOW BIG MUDDY RIVER, NEAR KLICKITAT, WASH.

From October, 1904, to June 26, 1908, the Klickitat Irrigation & 

Power Co. made a series of measurements on Big Muddy River and 

Klickitat River above and below the mouth of the Big Muddy. 

Through the courtesy of the company the results are presented here 

as furnished, except that, following the rule of the Geological Survey, 

discharge data are given only to three significant figures. They were 

computed to hundredths of a second-foot by the company. No gage 

heights were recorded.

In 1908 and 1909 William K. King, chief engineer of the Klickitat 

Valley Development Co., made some discharge measurements and 

had gage readings taken to determine the discharge at the lowest 

stage during the winter of 1908-9. The results are published here 

through the courtesy of Mr. King.

The discharge measurements were made with a Lallie meter, the 

rating table furnished by the manufacturers being used. Later this 

meter was rated at the United States Geological Survey rating station at Chevy Chase, Md., and it was found that the manufacturer's 

table gave velocities nearly 17 per cent too low. The original notes 

of Mr. King have therefore been recomputed, and a revision of his 

first estimates is given below.

The first gage established by Mr. King was near the Camp Klickitat 

gaging bridge of the Klickitat Irrigation & Power Co., in the NE. \ sec. 

10, T. 7 N., K. 12 E., and the measurements were made from the
NOKTH PACIFIC COAST. 415

bridge. The results are therefore comparable with those obtained by 

that company.

Two measurements were made at this point and gage heights were 

observed during September and October, 1908. From these the 

table of discharges has been computed.

KLICKITAT EIVEE AT HANSON'S CABLE, NEAE KLICKITAT, WASH.

The second gage installed by Mr. King was at Hanson's cable, a 

short distance below the mouth of Outlet Creek. This gage was read 

during the fall and winter of 1908-9, and probably represents as 

severe low-water conditions during the winter as will be encountered.

KLICKITAT KIVER AT WELS FERRY, NEAR LYLE, WASH.

In 1908 and 1909 daily gage heights were recorded at Wels Ferry, 

about 8 miles below Klickitat, and about 6 miles above Lyle, Wash., 

by Ham, Yearsley & Ryrie, of Spokane. These heights are published through the courtesy of that firm.

KLICKITAT RIVER AT KLICKITAT, WASH.

This station, which is located at Klickitat, Wash., 14 miles above 

the mouth of the river, was established July 3, 1909, to obtain data 

for use in connection with power and irrigation projects.-

The gage is a vertical staff fastened to an oak stump on the right 

foank in line with the post office. Measurements are made from 

the Spokane, Portland & Seattle Kailway bridge, three-fourths of 

a mile above the gage.

The banks of the stream are high and rocky and will not overflow. 

The bed of the stream is composed of gravel and cobblestones and 

is fairly permanent. There are no irrigable lands in the immediate 

vicinity of the station, but the waters may be diverted to higher 

lands bordering Columbia River. Plans for diversion and storage 

of water to irrigate the high table-lands that lie between Yakima 

and Columbia rivers, known as Horse Heaven Plateau, have been 

made. The construction of this canal will involve the expenditure 

of many millions of dollars, as a canal 119 miles long would have 

to be constructed before irrigable lands are reached; but the lands 

are exceedingly fertile and climatic conditions are favorable for intensive agriculture. The diversion point for this project would necessarily be some point in the vicinity of West Fork of Klickitat River, and 

considerable storage would have to be developed in order to provide 

a sufficient water supply.

WHITE SALMON RIVER DRAINAGE BASIN. 

DESCRIPTION.

White Salmon River has its source in three glaciers on the West 

side of Mount Adams. The largest of these is White Salmon River 

Glacier. To the north of this lies Pinnacle Glacier and to the south 

Avalanche Glacier. The river flows southward and empties its 

waters into Columbia River at the town of Underwood. The source 

and mouth of the river lie on the same meridian. The river has a 

total length of 38.5 miles and a total drainage area of 352 square 

miles.

Trout Creek is the principal tributary. It drains the high spurs 

and secondary peaks tp the southwest of Mount Adams, flows in a 

southeasterly direction, and empties into White Salmon River near 

Trout Lake post office. Three small creeks Big Spring Creek from 

the west and Gilmer and Rattlesnake creeks from the east empty 

into the river below Trout Creek in the vicinity of Husum. Gotchen 

Creek, the principal tributary above Trout Creek, drains the high 

spurs to the southeast of Mount Adams.

The drainage area of White Salmon River is distributed as follows:

The prominent topographic feature of the area is Mount Adams 

and the spurs and secondary peaks that surround it. These peaks
NOBTH PACIFIC COAST. 421

crown the bounding lines of the drainage area, which is roughly 

V-shaped, with Mount Adams at the apex. On the west Steamboat 

Mountain (at an elevation of 4,600 feet), the Castle (5,100 feet), and 

Old Huckleberry (5,200 feet) stand like sentinels on the summit of 

the divide. South Butte (7,790 feet), Snow Plow (5,070 feet), 

Snipes Mountain (4,800 feet), King Mountain (4,710 feet), and Snow 

Mountain (3,620 feet) prominently mark the eastern boundary. 

The basin is therefore roughly trough shaped, with several smaller 

peaks within it. The topography is bold and picturesque. The 

streams flow in deep canyons on beds of bowlders, with here and 

there ledges of basalt or stretches of box canyons that have vertical, 

jagged sides and solid beds.

The whole drainage basin is covered with lava and basalt, in which 

the canyons have been carved. Near Mount Adams many cinder 

cones and bombs give evidence of recent volcanic activity. Red 

Butte, 3 miles northeast of Mount Adams, has an elevation of 7,203 

feet. The cone is 500 feet high, with a crater 175 feet in diameter 

and 75 feet deep. Much of the pumice, scoria, and lava from these 

cones is highly colored, and volcanic glass is found in various shades 

from black masses to transparent globules. The bombs on the 

lower slopes of Mount Adams are rough spherical masses of lava, of 

homogeneous texture, ranging up to 30 feet in diameter. Near the 

headwaters are large areas of partly exposed lava beds. A line of 

caves may be traced along this formation for 20 miles or more. In 

some places the caves have been formed by the liquid mass flowing 

from under a solidified crest; in others they may have resulted 

from the action of gases and are in effect huge bubbles. One of these 

in sec. 25, T. 6 N., R. 9 E. is widely known as the Ice Cave. The 

temperature is so low that water accumulating and freezing during 

the winter does not thaw out during the following summer. The 

ice is found in masses on the floor and in stalactites and stalagmites 

formed by surface water dripping through" crevices in the roof. 

These form during the winter and are partly melted during the summer. The area in which these caves lie is drained by Trout Creek. 

The basin contains several small intermittent watercourses in which 

the water sinks at many points. It is likely that much of the surface 

water finds its way deep into these lava beds, emerging into lower 

portions of "White Salmon River or even into the adjacent drainage 

basin of Little "White Salmon River.

The mam river flows in a deep canyon whose sides are bordered 

by heavily rolling table-lands or mountains. From a point 3 miles 

below Trout Creek to a point 2J miles above Husum the river flows 

in a narrow box canyon. This has been cut squarely into the basalts 

and the recent lava flows that have overspread them. The canyon 

is about 11 miles long and nearly every part of it would afford a 

favorable site for a dam. Trout Creek, on the other hand, is essen-
422 SURFACE WATER SUPPLY, 1909, PART XIT.

tially a surface stream below Trout Lake. The banks are bordered 

by fairly level stretches of- open meadows and agricultural land.

The north line of T. 6 N. forms the southern boundary of the 

Columbia National Forest. Logging operations have been carried 

on for years in this drainage area, for the most part on lands adjacent to the river. The entire drainage area is heavily forested except 

where cleared for agriculture. Within the national forest the timbered area constitutes 73 per cent of the total, 26 per cent is burned, 

and 1 per cent is above timber line. The species are distributed in 

about the same proportion as those in the adjacent Klickitat basin, 

except that there is more red or yellow fir and less yellow pine. The 

stand of timber within the national forest is about as follows:

cent. 

0 to 2,000 feet b. m. per acre..................................... 18

2,000 to 5,000 feet b. m. per acre..................................... 30

5,000 to 10,000 feet b. m. per acre................................. 40

10,000 to 25,000 feet b. m. per acre................................ 8

25,000 to 50,000 feet b. m. per acre................................ 4

There are no railroads in the drainage area except the Spokane, 

Portland & Seattle Railway, which crosses the river at its mouth in 

its course along the right bank of Columbia River. The principal 

towns are Underwood and White Salmon, the latter being on the 

high table-land east of the river near its mouth. Husum post office 

is at the mouth of Rattlesnake Creek. Trout Lake post office is 

near the mouth of Trout Creek, on the east side of the river, and 

Guler is on Trout Creek near the outlet of Trout Lake. Good wagon 

roads and stage lines connect all the towns. The upper portion of 

this area is a favorite summer resort, and many campers will be 

found around Trout Lake and Guler in the summer.

The rolling benches along the lower part of the river have been 

cleared for agriculture. Most of these lands are in orchards and the 

territory has become justly famous for the excellent quality of its 

apples and other fruit. In T. 6 N. the lands along the river are 

comparatively flat, and some of them were natural meadows. These 

open lands have been enlarged by clearing the timber around them, 

and the whole valley presents a delightful picture of prosperity. In 

this portion of the valley irrigation is practiced extensively. The 

water for the ditches is diverted from Trout Creek and White Salmon River. These ditches are small but numerous, and they have 

an abundant supply of water.

At present lumbering is the principal industry of this territory. 

The Wind River Lumber Co. has constructed several splash dams 

on White Salmon River by means of which logs are floated from the 

upper portion of the drainage area to the mouth of the river, where 

they are gathered and transported in rafts to the mills on the lower 

Columbia.
NORTH PACIFIC COAST. 423

At Husum is a small power plant owned and operated by the 

Husum Power Co. The present capacity of the plant is 200 horsepower. It is developed by a twin turbine with 26-inch wheels, belt 

connected to a 75-kilowatt alternator, generating at 2,300 volts. 

Current is transmitted to White Salmon, 6^ miles, and up the valley 2 miles, for lighting and power. The water is supplied to the 

wheels by a canal 200 feet in length. The canal normally carries 

120 second-feet and develops a head of 17 feet around falls in the 

river at this point.

So far as known the basin affords no large reservoir sites. Trout 

Lake is the only flat area that would be suitable, but the outlet is 

a broad valley, and no favorable dam sites are found. Most of the 

water runs off during the spring, exposing the lake bed as a marshy 

flat. A small amount of storage might be developed at Steamboat 

Lake near the headwaters of Trout Creek.

Owing to the porous lava rocks of which the area is composed and 

the soil resulting from its disintegration, a large amount of water is 

held in ground storage. Springs are numerous along the river and 

seepage into it is large. Most of the summer flow, however, is supplied by the glaciers on Mount Adams. Above Trout Creek, White 

Salmon River has its lowest discharge during cold weather, while on 

hot summer days the discharge is high, and the water is heavily loaded 

with glacial silt. Trout Creek, on the other hand, has its lowest 

period at the end of the summer season. During the winter months 

the discharge is relatively high from surface drainage from the large 

area through which it flows. The two streams therefore maintain 

a well-balanced flow during the year. Floods occur during heavy 

rains when accompanied by chinook winds, which suddenly melt the 

snow on the hills. The heaviest floods are likely to occur in the 

autumn after an early snowfall. A flood from this cause of greater 

or less magnitude may be expected about the middle of each November and at other times during the winter months. Spring floods 

dccur periodically, but are rarely so severe as the fall floods and are 

not so sudden. These result from the more gradual melting of snow 

in the mountains as warm weather approaches. This melting is 

arrested at night, with the result that the stream shows daily variations of considerable magnitude.

No discharge data are available except those gathered during the 

course of the water power survey made by the United States Geological Survey in the summer of 1909.1 Measurements were made 

at several points on the main stream and its tributaries. The 

stream-flow data obtained during the investigation are included in 

the present report.

1 For the results of this investigation including profiles of the rivers surveyed see Stevens, J. C., Water 

powers of the Cascade Range, pt. 1, Southern Washington: Water-Supply Paper U. S. Geol. Survey No. 

253, 1910.
424 SURFACE WATER SUPPLY, 1909, PART XII.

Owing to the steep grade, well-maintained summer flow, and rocky 

canyons through which White Salmon Eiver flows, opportunities for 

water-power developments are abundant. The average fall of the 

main river for that portion surveyed 32.1 miles is 83 feet to the 

mile. Nine miles of the river's course above the mouth of Gilmer 

Creek has an average fall of 117 feet to the mile; in the last 3 miles the 

fall averages 53 feet to the mile. Trout Creek falls 115 feet from Trout 

Lake to its mouth, somewhat more than 2 miles. Where the north 

line of sec. 25, T. 5, R. 10, crosses White Salmon Eiver there are two 

falls with a total drop of 35 feet. At Husum there is a drop of 15 feet, 

and at a point 4 miles above the boundary of the national forest there 

is a drop of 5 feet.

The Wind Eiver Lumber Co. has splash dams for floating logs 

in sec. 14, T. 6, E. 10; sec. 6, T. 5, R. 11; and sec. 14, T. 3, E. 10. 

The waters of the river are used extensively for this purpose, and 

doubtless certain water rights have attached.

WHITE SALMON RIVER AT HUSUM, WASH.

This station, which is located 1,200 feet above the falls, 1,600 feet 

above the highway bridge at Husum, Wash , and is 7-| miles above 

the mouth of the river, was established September 23, 1909, to obtain 

data concerning the low-water flow of the stream.

Discharge measurements are made from the bank by means of a 

meter suspended on a light cable. No equipment has been installed 

for making measurements at high stages. Just below the station is a 

flume which diverts water for the Husum power plant. The gage is 

%a vertical staff in two sections.

The following discharge measurement was made by H. D. McGlashan:

September 23, 1909: Width, 93 feet; area, 249 square feet; gage height, 3.12 feet; 

discharge, 621 second-feet.

TROUT CREEK AT GULER, WASH.

This station, which, is located at Guler post office, Wash., 2 miles 

above the mouth of the creek, one-fourth mile below Trout Lake and 

above all diversions for irrigation, was established September 16, 

1909, to obtain data concerning low-water stages.

The gage is on the left bank 500 feet below the highway bridge on 

the meridian line between sees. 22 and 23, T. 16 N., R. 10 E. The 

lower section is inclined and reads to 3 feet. The upper section is 

vertical and reads from 3 feet to 11.5 feet. At low water the measurements are made by wading, and from the highway bridge during 

high stages. Sufficient measurements have not yet been made to 

fully develop a rating curve.

The following discharge measurement was made by H. D. McGlashan:

September 16,1909: Width, 37 feet; area, 34 square feet; gage height, 1.32 feet; discharge, 47 second-feet.

Daily gage height, in feet, of Trout Creek at Guler, Wash., for 1909.

426 SURFACE WATER SUPPLY, 1909, PART XII.

LITTLE WHITE SALMON RIVER DRAINAGE BASIN. 

DESCRIPTION.

Little White Salmon River drains the extreme south end of the 

Cascade Range in Washington. It lies between the main summit of 

this range and the White Salmon River drainage basin. The river 

rises on Old Huckleberry Mountain, at an elevation of 5,200 feet, 

flows almost directly south, and empties into Columbia River near 

the town of Cooks, 6J miles downstream from the mouth of White 

Salmon River. The principal tributaries enter from the west, and 

in order downstream are Moss Creek, Lava Creek, and Rock Creek. 

The main river has a total length of 17 miles and a total drainage 

area of 132 square miles. The drainage area above Moss Creek is 37 

square miles, and at a point below the mouth of Lava Creek 110 

square miles. Lava Creek drains 72 square miles.

The general topographic features of the country are similar to those 

of the territory drained by White Salmon River. Old Huckleberry, 

the highest mountain, has no well-defined summit, but is rather an 

elongated ridge with projecting spurs to the north and south. The 

area is rough and mountainous. The stream flows in a very deep 

canyon with steep and rugged sides. There are benches paralleling 

the river several hundred feet above the water surface for a portion 

of its length. The immediate valley is occupied almost entirely by 

the stream, the flood plain being very narrow.

The forests on this area are similar to those in the Klickitat and 

White Salmon drainage basins, previously described, except that the 

stand is heavier and the species show the change from a semiarid to 

a humid climate.

The southern boundary of the Columbia National Forest crosses 

the river about 7 miles above its mouth. Within this area 93 per 

cent of the land is covered with forest and 7 per cent has been burned. 

Nearly all of the burned areas are being restocked, and the forest 

cover has been established. About 55 per cent of the stand of timber 

is red and yellow fir, 10 per cent hemlock, 10 per cent red cedar, 5 

per cent white pine, 5 per cent yellow pine, and 15 per cent other 

species. The average stand of timber for this drainage area is over 

4,000 feet board measure per acre; 24 per cent of the area has a stand 

of less than 2,000 feet board measure per acre, 60 per cent from 2,000 

to 5,000 feet, 7 per cent from 5,000 to 10,000 feet, and 9 per cent from 

10,000 to 25,000 feet.

There are no railroads in the drainage area except one which crosses 

the river at its mouth. A wagon road follows the main river from 

Cooks to the head of the stream. Agriculture is not extensively 

practiced, although a few small tracts, mainly on bench lands along
NOETH PACIFIC COAST. 427

the river, have been cleared and planted to crops. On the right bank, 

3 miles above the mouth, there is a bench containing over 600 acres. 

The timber on this bench has been logged and the land is now on the 

market at $150 an acre. The conditions are favorable for raising 

fruit. On the opposite side of the river is another narrow bench 

extending for several miles upstream. These lands would doubtless 

raise fruit of good quality if cleared. It is estimated that there are 

30,000 acres of land in the Little White Salmon River drainage area 

suitable for agriculture after the timber has been removed.

The principal industry at present is lumbering. Large quantities 

of timber have already been cut from the area outside of the national 

forest. The logs removed are generally hauled by wagon down the 

canyon road. One mill is in operation at present 3 miles above the 

mouth. The sawed lumber is floated in a flume to Columbia River. 

During the summer of 1909 the United States Geological Survey 

made a water-power survey of this river and its tributaries. A 

river profile was made and the summer flow determined at several 

points. 1 The stream-flow data obtained during this survey are included 

in this present report. No other discharge data has been obtained 

on this stream by the Geological Survey prior to 1909. The river 

is subject to heavy floods during the fall and winter, and the summer 

discharge is comparatively low. During the summer months the 

principal source of supply is Moss Creek. Though this stream is not 

long, it is probably well supplied with water from underground 

sources. Lava Creek is an intermittent stream flowing through 

lava beds, and although its drainage area is comparatively large, 

a large proportion of the water falling upon it sinks into the ground, 

probably to reappear at points farther down. It is very likely 

that Moss Creek receives considerable water from the territory 

through which Lava Creek flows.

The porous texture of the lavas that cover these areas tends to 

vitiate any and all laws of stream discharge when expressed in terms 

of drainage area.

This stream affords an opportunity for a comparatively small 

plant under a high head. It is likely that during nine months of the 

year considerable power could be developed, but in the summer 

season the water supply is too small for a plant of large capacity. 

If developed, water would be diverted below the mouth of Lava 

Creek and carried about 6 miles along the side of the canyon in a 

pressure pipe. In this manner over 1,100 feet of head could be 

utilized.

1 For the results of this investigation, including profiles of the rivers surveyed, see Stevens, J. C., Water 

powers of the Cascade Range, pt. 1, Southern Washington: Water-Supply Paper U. S. Geol. Survey No. 

253,1910.

LITTLE WHITE SALMON EIVEE BELOW LAVA CEEEK, NEAE COOKS, WASH.

From 1903 to 1906 the Portland Railway, Light & Power Co. 

made determinations of discharge of Little White Salmon River 

below Lava Creek, about 5 miles north of Cooks, Wash. A rectangular weir, 16.2 feet in length, was installed and daily records kept. 

Through the courtesy of the company these records are given in 

the following table:

Daily discharge, in second-feet, of Little White.Salmon River below Lava Creek,near Cooks

Wash., for 1903-1906.

430 SURFACE WATER SUPPLY, 1909, PART XII.

LITTLE WHITE SALMON RIVER NEAR COOKS, WASH.

This temporary station was established October 4, 1909. It is 

located at the fish hatchery one-half mile above the mouth of the 

river near Cooks, Wash. The gage is a vertical staff spiked to the 

right abutment of a bridge supporting an old lumber flume 200 feet 

below the fish hatchery. Measurements are made by wading a 

short distance below the gage. No permanent equipment has been 

installed for making measurements at high stages, as at such times 

the station is not beyond influences of backwater from Columbia 

River.

The following discharge measurement was made by H. D. McGlashan:

October 4, 1909: Width, 84 feet; area, 136 square feet; gage height, 2.09 feet; discharge, 170 second-feet.

Daily gage height, in feet, of Little White Salmon River near Cools, Wash., for 1909.

SANDY RIVER DRAINAGE BASIN. 

DESCRIPTION.

Sandy River has its source in the glaciers of Mount Hood and flows 

northwestward and unites with Columbia River at Troutdale. It 

drains the eastern slope of the Cascade Mountains at the very north-
NORTH PACIFIC COAST. 431

ern extremity in Oregon. The principal tributaries are Bull Run 

River, which drains the Bull Run National Forest and furnishes the 

water supply for the city of Portland; Salmon River, the Little 

Sandy, and Zigzag, Camp, and Still creeks. The elevation at Bull 

Run post office is 647 feet above sea level; at Salmon post office, 

1,000 feet; at Bull Run Lake, 3,161 feet; and at Government Camp, 

3,880 feet. The summit of Zigzag Mountain is 5,014 feet in altitude 

and that of Mount Hood 11,225 feet. The drainage area includes 

521 square miles at the mouth of the river, 228 square miles above 

the mouth of Bull Run, and 118 square miles above the mouth of 

Zigzag Creek. The drainage area of Bull Run River at the mouth is 

168 square miles.

The mean annual precipitation at Bull Run is 76 inches; at Government Camp, 87 inches. It is likely, however, that the figure for 

Government Camp is not representative, because of the close proximity of the station to Mount Hood. A large part of the precipitation 

on the headwaters falls as snow. In the foothills, however, it nearly 

all appears as ram during the nine months from September to May. 

The value of the waters of this stream lies in their availability for 

municipal water supplies and in the water power that can be generated by them. Favorable sites for power development are numerous 

and the distance to an industrial center is not great. A large portion 

of the drainage area is heavily forested, although there are many 

areas from which the timber was burned a good many years ago. 

These areas have, however, grown up in second-growth timber and 

the underbrush is almost impenetrable.

As is usual with glacial streams, a protracted period of cold weather 

is very likely to cause lower water for a short period in winter than 

the natural low-water flow in the summer time.

SANDY RIVER AT SALMON, OREG.

This station was established December 12, 1907, at a highway 

bridge 1 mile below Salmon post office, Oreg. It is 1 mile below the 

mouth of Salmon River. This station furnishes data of value hi connection with water-power development. The chain gage is located 

on the upstream side of the highway bridge from which the discharge 

measurements are made.

Conditions at the station are favorable for individual measurements of considerable accuracy during medium and low stages; at a 

high stage, however, the current is very swift and somewhat turbulent. During the summer months glacial silt is deposited, which 

destroys the stability of the rating at low stages.
432 SURFACE WATER SUPPLY, 1909, PART XII.

The following discharge measurement was made by R. B. Post:

September 11, 1909: Width, 86 feet; area, 253 square feet; gage height, 3.33 feet; 

discharge, 352 second-feet.

Daily gage height, in feet, of Sandy River at Salmon, Oreg^for 1909.

BULL KUN RIVER NEAR BULLRUN, OREG.

This station was established August 20, 1907, by the water board 

of the city of Portland in cooperation with the United States Geological Survey, to obtain data in regard to the water supply. A 30- 

mile pipe line diverts water at this point for the city of Portland. 

The drainage area of the stream is very densely forested and the 

water is exceptionally clear and pure.

The staff gage which is located just above the intake to the Portland water supply pipe line was read throughout the year, but as 

gage heights were affected at low stages by a temporary brush dam 

that was constructed for diverting water into the pipe line a Friez 

self-registering gage was installed July 28, 1909, at the cable site 1£ 

miles above the intake. Since August 1, 1909, observations of gage 

heights have been made from both gages. During periods of extreme 

flood, or during intervals when the Friez gage was not recording) 

gage heights have been estimated for the upper gage by means of the 

relation which has been established between the two gages. In this 

manner a continuous record has been secured.

NOTE. The discharges are based on rating curves applicable as follows: Jan. 1 to July 31, fairly well 

defined and applied to staff gage records; Aug. 1 to Dec. 31, well defined between 80 and 230 second-feet; 

fairly well defined above 230 second-feet. Applied to Friez automatic gage records. For days on which 

automatic gage record is missing discharge has been obtained from an estimated gage height, which is 

determined from relation of staff gage.

436 SURFACE WATER SUPPLY, 1909, PART XII. 

WILLAMETTE RIVER DRAINAGE BASIN. 

DESCRIPTION.

Willamette River drains a trough-shaped area, extending north 

and south between the Coast and Cascade ranges in Oregon. The 

area is roughly rectangular, approximately 230 miles hi length and 

about 85 miles in width. The Willamette proper is formed by the 

junction of three main tributaries which unite in the vicinity of 

Eugene; these are the Coast Fork, the Middle Fork, and the McKenzie. 

The river is navigable for ocean-going vessels from the mouth to 

Portland, and for ordinary river steamboats from Portland to Corvallis, except during a few months of each year. From Corvallis to 

Eugene the river is navigable for light-draft boats during medium 

stages of the river. The falls of Willamette River at Oregon City 

are passed by a series of five locks, which are at present in private 

ownership.

The other principal tributaries of Willamette River ape Santiam, 

Molalla, and Clackamas rivers. From the Coast Range flow Long. 

Tom, Marys, Luckiamute, Yamhill, and Tualatin rivers. The 

drainage areas of this river and its principal tributaries are given in 

the following table:

From the summit of the mountain ranges the slopes are steep, but 

they merge gradually into a wide alluvial valley or gently rolling 

agricultural lands.

The entire drainage area of this river was originally primeval 

forest, and although considerable areas in the valley have been 

cleared for agriculture the area may still be considered densely forested. The portions of the basin that contribute most to the flow of 

the streams are almost entirely within the boundaries of the national 

forests, while the privately owned timber lands extend from the 

boundaries of the national forests to the main stream in the valley, 

except where lands have been cleared. Thus whatever beneficial 

influence the original forest may have exerted on the regulation of 

stream flow, its effect is still in evidence, as the water-producing 

portions of the area have not been disturbed.
NOKTH PACIFIC COAST. 437

The mean annual rainfall presents some rather peculiar features. 

Although precipitation records at the summit of the Coast Range 

are meager, it is likely that the total annual rainfall is as much as 

150 inches. As the eastern slope of the Coast Range is descended, 

precipitation falls very rapidly to about 40 inches, but gradually increases again until at the summit of the Cascade Range it is approximately 100 inches annually. From north to south the same general 

variation is observed; although the differences are not so striking. 

At the mouth of the river the precipitation is approximately 50 inches, 

which gradually decreases to about 40 in the vicinity of Corvallis, 

but increases again to 55 or 60 inches at the summit of the Calapooya 

Mountains, which form the southern boundary of the drainage area. 

Except on the summit of the mountain ranges this precipitation 

appears almost entirely as rainfall, 95 per cent falling during nine 

months, from September to May. On the mountain ranges part of 

the precipitation is snowfall, and the country is subject during the 

spring and fall to warm chinook winds, accompanied by rather 

sudden melting of these snows, which frequently cause considerable 

damage from floods. During the growing season when the precipitation rarely exceeds 2 inches, the country is practically an arid section. 

Although irrigation has not been practiced hi the valley, it is likely 

that before many years a large part of the agricultural bottom lands 

will be placed under irrigation. Small ditches and pumping plants 

have been constructed, and the returns from irrigated agricultural 

lands show an increase of from 50 to 500 per cent in production over 

the nonirrigated lands.

This area has never been mapped topographically, so that it is impossible to determine the extent of storage facilities. The operation 

of storage reservoirs would, however, greatly increase the economic 

value of the river system, as it would probably render the river navigable from Eugene to its mouth during all portions of the year and at 

the same time diminish the damage from floods that annually threaten 

the agricultural lands and the industries of the valley. It would also 

make the river many times more valuable than it is at present for 

water-power development.

The highest known flood hi the Willamette Valley occurred December, 1861, when the discharge at Albany was 220,000 cubic feet per 

second. The highest gage reading at Portland since that date occurred in 1894, but was due to backwater from Columbia River. 

The years 1899 and 1907 were "wet years." The year 1905 was a 

comparatively dry year. The longest record of stream flow in this 

basin has been obtained by applying recent measurements made at 

Albany to records obtained by the United States Weather Bureau 

since 1895.
438 SURFACE WATER SUPPLY, 1909, PART XII.

MIDDLE FORK OF WILLAMETTE RIVER AT JASPER, OREG.

This station was established September 16, 1905, at the ferry 

near Jasper post office, Oregon, 2 miles above Natron and 3 miles 

below the mouth of Fall Creek.

The waters of this stream are particularly valuable for water 

power and will probably be used in the future for irrigation. The 

records also furnish some very reliable data concerning the run-off 

from heavily forested areas where the precipitation is high. A 

recently constructed storage reservoir at Waldo Lake on the North 

Fork of Middle Fork seems to augment the summer flow over what 

formerly obtained. Stored water was released during August and 

September, 1909.

The vertical staff gage is on the right bank about 30 feet above 

the cable. Discharge measurements are made from a cable equipment. The stream is largely used for transporting logs during all 

seasons of the year, and records of flow are therefore somewhat 

unreliable during the low-water periods, as logs frequently ground 

on the bars below the station and cause backwater on the gage. 

Except for this, the records are reliable, and no change of gage datum 

has occurred since the station was established.

WILLAMETTE RIVER AT ALBANY, OREG.

On July 21, 1905, the United States Geological Survey, established 

a station at the Corvallis & Eastern Railroad bridge within the city 

limits of Albany, Oreg. It is below the mouth of Calapooya River 

and 7 miles above the mouth of Santiani River. The staff gage is 

located on the second pier from the right bank and discharge measurements are made from the railroad bridge.

The United States Weather Bureau has maintained records of gage 

heights at Albany, Oreg., since 1879. On September 27, 1906, the 

Weather Bureau gage was moved from its former location on the 

steel highway bridge, 2,000 feet above the railroad bridge, to a better and more convenient location. The present gage is in two sections. The first is attached to one of the piers of the dock of Westgate Bros. The high-water section is attached to their warehouse 

and 30 feet nearer the shore.

Continuous records of gage heights have been obtained from the 

United States Geological Survey gage since the station was established, but as conditions are more favorable for better results at the 

upper sections estimates have been computed based o~n the Weather 

Bureau gage heights. 1 In constructing the rating curve for this gage 

the earlier measurements at medium and low stages have been 

platted as coordinates with the Weather Bureau observer's reading 

for the day.

The data at this station are especially valuable in the determination 

of run-off values from forested areas and will be of economic impor1 Monthly and yearly estimates of discharge for 1879,1892 to 1908 were published in Water-Supply Papei 

U. S. Geol. Survey No. 252, 1910, pp. 354-358. l

tance in the proper design of river improvements for navigation purposes and in the development of water power and irrigation.

No discharge measurements were made during 1909.

The gage heights for 1909 were furnished by the United States 

Weather Bureau.

WILLAMETTE RIVER AT OREGON CITY, OREG.

This station is located about a mile below the falls at Oregon City, 

Oreg., and above Clackamas Rapids.

Gage heights are obtained from a vertical staff gage located at the 

foot of the falls in the lower locks, and have been recorded since 

August 19, 1883. The gage heights are affected by back water from 

Columbia River at high stages, and probably by back water from 

Clackamas River at high stages of that stream, but during the summer months the gage heights would be fairly good index of the discharge. The station was established by the Portland Railway, Light 

& Power Co. with the intention of developing a discharge curve to 

which the old gage heights during the summer months could be 

applied.

At ordinary stages the waters of Willamette River at this point 

are entirely used for power development. The Portland Railway,
NOBTH PACIFIC COAST. 443

Light & Power Co. has the major interest in the water rights at this 

point. Besides furnishing power for municipal uses at Portland, the 

company leases power to the several paper mills at Oregon City. 

The aggregate installation of power wheels probably amounts to 

40,000 horsepower, but there is only sufficient water;to develop 

10,000 horsepower at low stages of the river. During such periods 

the paper mills are obliged to use steam power or suspend work. 

The Portland Railway, Light & Power Co. also owns and operates 

the locks at this point. The fall of the river at low water is about 41 

feet, and a dam has been constructed around the brink of the falls 

where, by means of flashboards, the head is increased for low stages 

of the river. This causes backwater for many miles up stream, and it 

was impossible to select a site where a discharge curve could be developed for all stages of the river. The point selected was the only one 

in that vicinity where the determination of discharge could be made, 

and here the flow will be more or less under artificial control.

Discharge measurements are made from a boat held by a cable 

which is stretched across the river at the time of gaging. Up to the 

present time a sufficient number of measurements have not been 

made to develop a rating curve here.

KELSEY RIVER NEAR HAZELDELL, OREG. 1

Kelsey River is the next important tributary of the Middle Fork 

of the Willamette above the North Fork.

This station was established October 12, 1909, in cooperation with 

the United States Geological Survey by the Waldo Lake Irrigation 

& Power Co. at a highway bridge on the Willamette military road, 

1 mile above the mouth of the stream.

The chain gage is attached to the wagon bridge,, from which discharge measurements are made at high water. Measurements at low 

water are made by wading.

The right bank is high and rocky; the left is comparatively low and 

will overflow at high water. The bed is of gravel and cobblestones 

and fairly permanent. The data obtained at this station are valuable 

chiefly in connection with power development.

The following discharge measurement was made by A. P. Stover:

October 11, 1909: Width, 65 feet; area, 

charge, 139 second-feet.

NORTH FORK OF MIDDLE FORK OF WILLAMETTE RIVER NEAR HAZED*

DELL, OREG.

This station was established October 12, 1909, by the Waldo Lake 

Irrigation & Power Co., which cooperates with the Geological Survey 

in its maintenance. It is located half a mile above the confluence of 

the North Fork with the Middle Fork of Willamette River and hah6 

a mile below the Willamette military road crossing. A storage 

reservoir has been built at Waldo Lake, which makes possible the 

irrigation of considerable agricultural land in the lower valley. At 

present the waters are used principally for driving logs during the 

low-water season.

The gage is a vertical staff on the right bank, spiked to a maple 

tree. The discharge measurements are made by wading at low water, 

or from the highway bridge half a mile above at high water. Both 

banks of the stream are high, and the bed of the stream is composed 

of gravel and cobblestones, and is fairly permanent.

The data at present available are insufficient for a determination 

of discharge.

The following discharge measurement was made by A. P. Stover:

October 12, 1909: Width, 92 feet; area, 126 square feet; gage height, 1.03 feet; discharge, 165 second-feet.

Daily gage height, in feet, of North Fork of Middle Fork of Willamette River near Hazeldell, Oreg., for 1909.

COAST FORK OF WILLAMETTE RIVER NEAR GOSHEN, OREG.

This station was established August 23, 1905, and has been maintained continuously since that date. It is located at a highway 

bridge 3 miles east of Goshen, 9 miles southeast of Eugene, 5 miles 

west of Jasper, Oreg., and 4 miles above the mouth of Coast Fork.

The gage is in two sections. The lower section is nailed vertically 

to an old pier in the center of the stream, the upper portion is painted 

on the lower bridge caisson on the left b ank. Discharge measurements 

are made from the highway bridge.
446 SURFACE WATER SUPPLY, 1909, PART XII.

The records are of value in a general study of run-off conditions in 

the Willamette Valley. If storage could be supplied the stream 

would be valuable for both water-power and irrigation development. 

Gages have washed out at tunes, but they have been replaced at the 

same datum and no material inaccuracy in the records has been 

caused on this account.

The following discharge measurement was made by H. D. McGlashan:

Jan. 18, 1909: Width, 266 feet; area, 2,400 square feet; gage height, 10.02 feet; 

discharge, 14,800 second-feet.

Daily gage height, in feet, of Coast Fork of Willamette River near Goshen, Oreg., for 1909.

M KENZIE RIVER NEAR SPRINGFIELD, OREG.

This station was established September 12, 1905, and has been 

maintained continuously since that date. It is located at Hendricks 

Ferry an old river crossing that was replaced by a highway bridge 

in 1908 11 miles above Springfield, 3 miles below Waterville, 4 

miles above Thurston, Oreg., and 3 miles above £he mouth of Camp 

Creek.

The results obtained at this station have considerable economic 

value, as it is probable that this river will be extensively used for
448 SURFACE WATER SUPPLY, 1909. PART XII.

both irrigation and water power. The station also furnishes data 

for determining run-off factors from heavily forested areas with high 

rainfall.

The vertical staff gage is spiked to a small willow tree on the 

left bank about 250 feet above the cable station. Discharge measurements are made from a cable equipment. Those taken during 

high water in the past are not very reliable. Individual measurements at low and medium stages can be made with accuracy. No 

measurements were made during 1909.

The conditions at this station do not favor accurate results. The 

stream is extensively used for floating logs during all seasons of 

the year, and the gage records have been greatly influenced thereby. 

Individual daily records may be greatly in error, although it is probable 

that this error diminishes rapidly as records of longer periods are 

considered.

SANTIAM EIVEE DRAINAGE BASIN. 

MARION FORK OF SANTIAM RIVER AT MARION LAKE, NEAR DETROIT, OREG.

This station was established February 23, 1907, by J. G. Kelley, 

of Portland, Oreg., who furnished the records. It is located about 

200 feet below the outlet of Marion Lake, 30 miles from Detroit, 

Oreg., from which it is reached by trail, 

84547° WSP 272 11 20
450 SURFACE WATER SUPPLY, 1909, PART XII.

The gage heights for 1907 were obtained by measuring down from 

a reference point. From January to July, 1909, the gage used recorded maximum and minimum stages between observations. On 

August 1, 1909, a 15-foot rectangular weir was installed from which 

the discharges were determined until November 20, 1909, when it 

was washed away. These discharges have not been published as 

they are thought to be too small.

No discharge measurements have been made at this station since 

1907.

The results obtained at this station will be of value in connection 

with the development of water powers on this stream.

NORTH FORK OF SANTIAM RIVER NEAR DETROIT, OREG.

This station was established January 24, 1907, by J. G. Kelley, of 

Portland, who has cooperated with the Survey in its maintenance. 

The station is located at a footbridge 1 mile above Detroit, Oreg., 

about \\ miles above the mouth of Britenkmsh Creek, and 2 miles 

below the mouth of Bowlder Creek.

The records are of particular use in furnishing data for the development of water power, for which this stream is exceptionally valuable.
NORTH PACIFIC COAST. 451

As the low-water flow is the value specifically sought, no particular 

effort has been made to determine the flood discharge, and only the 

low-water records have been computed.

The station was discontinued October 31, 1909, in favor of another 

several miles upstream, where gaging conditions are better.

No discharge measurements were made during 1909, and no estimates of discharge are permissible with the data available. The 1907-8 

rating curve is not applicable.

SANTIAM RIVER AT JEFFERSON, OREG.

This station was established July 19, 1905, and was discontinued 

July 1, 1906, but was reestablished October 15, 1908. It is located 

at Jefferson, Oreg., 2 J miles below the junction of the North and South 

forks, measurements being made either from the highway bridge or 

from the Southern Pacific Railroad bridge. It is 9 miles above the 

mouth of the stream and below all tributaries.

The stream is particularly valuable for its water powers, although 

it seems probable that extensive use will be made of its waters for 

irrigation in the near future. The stream system is composed of two 

very dissimilar branches, the North and South forks. The total 

annual amount contributed by each fork is approximately the same, 

but the flow of the South Fork is very irregular, failing very low in the 

summer time and being subject to excessive and violent floods. The
452 SURFACE WATER SUPPLY, 1909, PART XII.

North Fork, on the other hand, maintains a well-established flow 

during the low-water season.

The original staff gage was located on a pier of the railroad bridge. 

It was impossible to obtain even approximate heights during flood 

stages. The records obtained prior to July 1, 1906, are not reliable. 

Since this station was established, October 15,1908, the gage installed 

by the Jefferson Mill Co. was used. It is located at the mill just 

above the bridge, where accurate gage heights can be obtained. This 

gage is at the same datum as the old gage. The United States 

Weather Bureau gage that is on the middle pier of the railroad bridge 

is also at the same datum.

Sufficient data are not at present available for an accurate determination of daily and monthly discharge.

NOETH PACIFIC COAST.

PUZZLE CREEK NEAR DETROIT, OREG.

453

A station on this stream was established at its mouth in February, 

1907, by J. G. Kelley, of Portland, who has cooperated with the 

United States Geological Survey in its maintenance. The gage 

heights were obtained by measuring down from a reference point, 

which had an assumed elevation of 10 feet. On August 6, 1909, 

6-foot rectangular weirs were installed on North and South forks 

of Puzzle Creek and were used to obtain the discharge until the 

November flood, when both weirs were washed out. The results 

obtained on both forks have been added, but are not comparable 

with those obtained at the mouth of the stream on account of intermediate drainage.

The data obtained at this station are valuable principally for use 

in development of water power.

No current-meter measurements have been made at this station 

since 1907.

NOTE. These estimates are based on the combined flow over a 6-foot weir on the North Fork and one 

on the South Fork, daily discharges for missing days being interpolated. The leakage through weirs, 

velocity of approach, and possible roundness of crests have been neglected. If any of these have any 

effect, the discharges as given are too small.
454 SURFACE WATER SUPPLY, 1909, PART XII.

PERMELIA CREEK NEAR DETROIT, ORE6.

This station was established February 23, 1907. It is located at 

the Minto trail crossing in sec. 33, T. 10 S., R. 7 E., about one-half 

mile above the mouth of the stream. The station has been maintained by J. G. Kelley, of Portland, Oreg., who furnishes the records.

The data are valuable principally in connection with a general 

study of the possibilities for water-power development on the North 

Fork of Santiam River. The gage heights are obtained by measuring 

down from a reference point, which is a spike in a 6-inch aldar on 

the left bank 30 feet upstream from the trail crossing.

No discharge measurements were made during 1909.

LUCKIAMUTE RIVER NEAR SUVER, OREG.

This station was established August 18, 1905, and has been maintained continuously since that date. It is located just below Helmick bridge on the public highway, 4 miles northwest of Suver, Oreg., 

4 miles south of Monmouth, and 3 miles below the junction of the 

North and South forks.

The staff gage is in two sections; the lower is an inclined rod driftbolted to a bridge post. The upper portion is vertical and nailed to 

a bridge timber. Discharge measurements are made from a cable 

equipment.
NORTH PACIFIC COAST. 455

The results furnish data valuable in the general study of run-off 

from the forested areas of the eastern slope of the Coast Range and 

are comparable in a general way with the records on Yamhill River. 

The river is subject to excessive and violent floods, due to the sudden 

melting of snows on the mountain slopes. At the station the river 

flows in a comparatively deep canyon and the records are believed 

to be reliable. No discharge measurements were made during 1909. 

It is believed that no changes occurred during the year to alter the 

rating.

YAMHILL RIVER DRAINAGE BASIN. 

SOUTH FORE OF YAMHILL RIVER AT SHERIDAN, OREG.

This station was established April 25, 1906. It is located at the 

highway bridge in Sheridan, Oreg., 2 miles below the mouth of Mill 

Creek. It was discontinued June 30, 1909, for lack of an observer.

The records determine in a general way the run-off from the 

eastern slope of the Coast Range and are particularly valuable in the 

study of forestry and run-off conditions. It is also probable that 

the waters will be used in the near future for irrigation.

The staff gage is attached to the right bridge pier.

No change in gage datum has occurred since the station was established. Discharge measurements are made from the highway bridge. 

The records are believed to be fairly reliable, although the conditions 

are not ideal. The banks of the river are densely covered with 

willows and brush that render the accurate determination of flood 

discharge difficult.
NORTH PACIFIC COAST. 457

No discharge measurements were made during 1909.

458 SURFACE WATER SUPPLY, 1909,, PART XII.

YAMHILL RIVER AT LA FAYETTE, ORE6.

This station was established October 6, 1908, for the purpose of 

developing a rating curve to be applied to old records of gage height 

obtained at the locks by the United States Weather Bureau and the 

United States Army engineers. It is located at the county highway 

bridge at La Fayette, Oreg., three-fourths of a mile above the locks 

and about \\ miles below the junction of the North and South forks.

The vertical staff gage is in two sections, attached to the north 

abutment of the highway bridge from which discharge measurements 

are made.

The data will be particularly valuable for determining the run-off 

from areas draining the eastern slope of the Coast Range. The 

run-off on this range is exceedingly high and the river is subject to 

excessive floods. They will also complete the study of general 

run-off conditions in the Willamette Valley.

No discharge measurements were made during 1909, and the data 

obtained are insufficient for a determination of discharge.

Daily gage height, in feet, of Yamhill River at La Fayette, Oreg., for 1909.

MOLALLA RIVER BASIN. 

MOLALLA RIVER NEAR MOLALLA, OREG.

This station was established November 1, 1905. It is located 

3 miles below the mouth of the North Fork of the Molalla on the 

farm of Raymond Dickey, 3| miles southeast of Molalla post office, 

Oreg.

This will probably be one of the first streams to be used for irrigation in the Willamette Valley, and for this reason the data are particularly valuable. The records also furnish a measure of the run-off 

from streams draining the foothills of the Cascades from which a 

part of the forest cover has been cut.

Since the establishment of the station the gage datum has not 

been changed, although the gage has washed out several times. It 

was replaced as soon as practicable afterwards, but there still remain 

intervals when the gage heights were estimated and on this account 

low-water estimates are impossible. The gage heights are affected 

somewhat by logs during the logging season. No discharge measurements were made during 1909. Ths conditions at the station 

require a large number of measurements each season, and on this 

account it was necessary to discontinue the records on July 12, 1909, 

until more funds are available.

Daily gage height, in feet, of Molalla River near Molalla, Oreg., for 1909.

CLACKAMAS RIVER DRAINAGE BASIN. 

CLACKAMAS RIVER NEAR CAZADERO, OREG.

This station was established January 1,1909, by the Portland Railway, Light & Power Co., with which the Geological Survey cooperates 

in its maintenance. The station is located 2 miles above the dam of 

the Portland Railway, Light & Power Co., at Cazadero, Oreg., and is 

above all backwater influence from that dam.
460 SURFACE WATER SUPPLY, 1909, PART XII.

The gage is a vertical staff graduated to feet and tenths, and reads 

sea-lsvel elevations (Portland Railway, Light & Power Co. datum). 

It is about 50 feet above the cable. Measurements are made from a 

standard cable and car equipment. The gaging section is located in a 

comparatively quiet pool just above a riffle and below a rather narrow box canyon. Conditions are not favorable for discharge measurements at high water, but are favorable for good results at medium 

and low stages. Both banks of the stream are high and rocky. The 

bed is composed of gravel and cobblestones. '

The station is at the second dam site of the Clackamas River 

development by Portland Railway, Light & Power Co., where it is 

proposed to erect a dam for the development of water power to be 

operated in conjunction with the plant .at Cazadero. Th3 data 

obtained ara therefore of value in this connection, and furnish reliable data for comparative purposes elsewhere.

A gage is also maintained at the company's dam 2 miles downstream where daily gage readings are obtained. The dam as first constructed had a triangular crest, downstream slope 2^:1 and upstream 

slope 6:1. In 1909 it was reconstructed. It is now of ogee cross 

section, constructed of timber with an upstream slope of 2|:1. The 

crest is at an elevation of 521.25 feet and is 170 feet in length and 

about 40 feet above the apron. The abutments of the dam extend 

upstream 53 feet from the crest. In the left abutment are located 

the gates for diverting water into the power canal, and the gage is 

located at the extreme left end of the left abutment, and hence is 53 

feet upstream from the crest of the dam. It is graduated in feet and 

tenths, and reads from sea level (Portland Railway, Light & Power 

Co. datum).

EVAPORATION STATION NEAR CAZADERO, OREG.

This station was established May 1, 1909. The evaporation pan 

is located in the forebay of the power plant of the Portland Railway, 

Light & Power Co., at Cazadero, Oreg. The pan is of standard type, 

3 feet square and 18 inches deep, with a needle point in the center to 

which the water surface can be adjusted at the time of observation. 

The observer is supplied with a cup, the contents of which will raise 

the water 0.1 inch. The elevation of the water surface in the forebay 

is about 520 feet above mean sea level.. The station is maintained 

in cooperation with the Portland Railway, Light & Power Co.

CLACKAMAS RIVER AT ESTACADA, OREG.

This station was established April 6, 1908, and replaces the station 

formerly maintained at Barton, Oreg. It is located on the Oregon 

Water Power Co.'s park at Estacada, Oreg., about If miles downstream from the Portland Railway, Light & Power Co.'s hydroelectric plant at Cazadero. The river at this point flows in a deep 

canyon, and it was impossible to find a site whicn combined proper

gaging facilities with easy accessibility. It was therefore necessary 

to install two gages. The upper gage No. 1 on which daily readings are made, is located at the foot of a stairway leading to the 

water's edge opposite the dance hall in the park. The cable from 

which measurements are made is located about one-fourth mile 

downstream from this point, where gage No. 2 was installed. All 

measurements have been referred to both gages. Between the two 

gages there is a small amount of inflow from springs, the larger being 

from the left bank just above the gaging site. The flow of these 

springs, however, is hardly over 1 per cent of the flow of the stream 

at extreme low water.

The nonuniform use of the water at the power plant causes daily 

fluctuations in the quantity of water passing the gaging station. 

This fluctuation is very noticeable at low water, but becomes relatively less at higher stages. On account of these artificial variations 

in flow it was necessary to establish a station out of influence of the 

power plant. Accordingly this station, 2 miles above Cazadero, was 

established January 1, 1909. The discharge at the two points 

should be virtually the same as there are no intervening tributaries.

For purposes of comparison, however, the discharges for 1909 at 

this station are given.

LEWIS RIVER DRAINAGE BASIN. 

DESCRIPTION.

Lewis River has its source in Adams Glacier, on the northwest 

slope of Mount Adams, flows in a general southwesterly direction, 

and empties into Columbia River 19 miles below Vancouver, Wash. 

Its lower half forms the boundary line between Cowlitz and Clarke 

counties, Wash.; its upper half is entirely within Skamania County. 

The total length of the main river is 110 miles, and the stream drops 

7,900 feet in that distance.

The principal tributaries in order downstream are, from the north, 

Muddy River, Pine Creek, Swift Creek, Cougar Creek, and Speilei 

Creek; from the south, Drift Creek, Siouxon Creek, Canyon Creek, 

Cedar Creek, and South Fork. Of these South Fork has the largest 

drainage area, but contributes a relatively small portion of the flow. 

Muddy River and Pine and Swift creeks supply a large part of the 

tributary discharge.

The total area drained by Lewis River is 1,070 square miles, distributed as follows:

466 SURFACE WATER SUPPLY, 1909, PART XII.

Mount Adams, 12,307 feet high, and Mount St. Helens, 9,750 feet 

(height not accurately determined), are the prominent topographic 

features of this territory. Mount Adams is just to the east of the 

summit of the Cascade Range and Mount St. Helens is 35 miles 

almost due west from Mount Adams and 14 miles southwest from the 

nearest point on the divide. Other peaks are Steamboat Mountain 

(4,600 feet) and The Castle (5,100 feet), standing southwest of the 

headwaters. Powderhorn Peak is near the mouth and north of the 

river.

The area is characterized by rough mountains and by ridges and 

spurs from the highest peaks. Toward the summit of the range the 

country becomes more abrupt and rugged. The streams all flow in 

canyons. In the upper portions the canyon sides are steep and 

rugged; in the lower stretches there are high benches of fairly level 

land and valleys of small extent bordering the river.

The rocks are almost entirely of igneous origin and comprise 

basalts, lavas, and pumice. Some recent lava flows lie around the 

bases of Mount St. Helens and Mount Adams. The rivers have cut 

deeply into these formations and in some places ten or more distinct 

lava flows can be counted. The soil resulting from the disintegration of these rocks is mixed with volcanic ash and is very fertile. 

Trees and brush grow in profusion, and where valley lands have 

been cleared good crops can be raised.

About one-fourth of the Lewis River drainage basin lies within the 

Columbia National Forest. Within this area the average stand of 

timber is over 13,000 feet b. m. per acre. The entire area is essentially densely forested, and although logging operations have been 

carried on for years the cut-over area forms a relatively small part 

of the total. The lands contiguous to the lower portion of the river 

are the only ones that show the effect of these logging operations, 

and they are rapidly being restocked except where they have been 

cleared for agriculture. Red and yellow fir are the predominating 

species and constitute about 50 per cent of the total stand. There 

are also large quantities of hemlock, Noble fir, and cedar. All through 

the forests the underbrush is very dense. Wherever the continuous 

shade of the large trees has been broken by logging or on burned areas 

the undergrowth is most pronounced. Salal, vine maple, huckleberry, 

dogwood, syringa, snowberry, wild rose, blackberry, and salmonberry 

are prevalent species. These, mingled with young seedlings of the 

conifers and with ferns, vines, and brambles and the decaying and 

moss-covered trunks of fallen trees, make an almost impenetrable 

mass.

The Seattle and Portland line of the Northern Pacific Railway 

crosses Lewis River near its mouth, and a logging branch line runs 

from Vancouver to Yacolt, near the headwaters of Cedar Creek. The
NORTH PACIFIC .COAST. 467

main stream is navigable for small boats as far as Ariel except during 

the low-water season. A river steamer runs regularly between Portland and Woodland, and a small steamboat runs from Woodland to 

Ariel, or Runyons Landing, as this place was known before the post 

office was established.

A wagon road follows the north bank of the river from Woodland to 

Petersons and there is a good trail from Petersons to Pine Creek. 

There is also a wagon road on the south side of the river from Woodland to Cressup's ferry. The drainage area of South Fork is not so 

mountainous and is much better improved, there being a goodly 

number of settlers and roads in all directions.

The percentage of'farming land in this area is comparatively small. 

Where timbered lands have been cleared, however, as along the rolling 

table-lands and broader valley of South Fork and the lower portions 

of the main river, good crops can be grown. Farther upstream the 

valley becomes narrower and the suitable farm land is in small benches 

or narrow strips in the floor of the canyon. All crops common to a 

mild and moist climate are grown. Fruits of all kinds are found in 

abundance. Apples, pears, cherries, and small fruits and berries are 

grown with excellent results. At present, however, the principal 

industry is lumbering. There are a number of lumber and shingle 

mills near the mouth of the river, although most of the logs cut are 

transported by water to the mills on Columbia River. At many 

points along the main stream flumes lead from the high mountains 

to the river bank. These are used for floating shingle bolts from the 

hills into the river.

So far as known there are no favorable sites where a large amount 

of storage could be developed. In the canyon of the main stream 

there are numerous dam ssites where a moderate amount of storage 

could be developed for the use of a power plant with daily load 

variations.

Lake Merrill lies on the divide between the headwaters of Cougar 

Creek and Kalama River. It has no surface outlet, but its waters 

probably find their way through the lavas that surround it into both 

these streams. It could doubtless be raised and water could be 

diverted in either direction, although diversion into Kalama River 

would be the easier. The formations indicate that the larger portion of the water now flows into Kalama River. The water surface 

of the lake is less than 1 square mile and the drainage area comprises 

6.9 square miles. During the summer of 1909 the United States 

Geological Survey made a water-power survey of this basin.1 Discharge measurements were made on all important tributaries and on 

the main stream at various points to determine the summer flow.

1 For the results of this investigation, including profiles of the rivers surveyed, see Stevens, J. C., Water 

powers of the Cascade Range, pf. 1, Southern Washington: Water-Supply Paper U. S. Geol. Survey 

No. 253,1910.
468 SURFACE WATER SUPPLY, 1909, PART XII.

The stream-flow data obtained during this investigation are included 

in the present report.

So far as could be learned at the time of this survey no records of 

discharge or gage heights have been kept on any of the streams hi 

this basin. There is a gage at Woodland which is used as a guide 

for determining the time of running boats, and another one was 

found at Ariel, but no systematic records of river heights have been 

kept from either of them.

Lewis River has a fairly well maintained flow during the summer 

season. This flow is largely supplied from the glaciers on Mount 

Adams and Mount St. Helens. The grade of the main stream, 

however, is not exceptionally steep until the ascent of the main 

range is begun. From Ariel to the falls, 14 miles above the mouth 

of Muddy River, the stream falls 1,495 feet in 51.4 miles, an average 

of 29 feet to the mile. In the upper 14 miles of this distance the 

average fall is 39.5 feet to the mile; in the last 7 miles the average 

fall is only 11.3 feet to the mile. Muddy River was surveyed for 9 

miles above its mouth, and an average fall of 44.4 feet to the mile 

was found. Pine Creek drops 233 feet in the last 1.6 miles, an average of 146 feet to the mile. Swift Creek has an average fall at its 

mouth of 172 feet to the mile, and Cougar Creek 125 feet to the mile.

Many favorable sites for dams are found along the main stream 

and tributaries! These occur where the canyons narrow to chasms 

with vertical jagged walls of solid rock. In many places bedrock is 

exposed in the bed of the stream or is lightly covered with gravel 

and bowlders. Along the canyon sides there are many benches upon 

which open canal construction would be possible. The more feasible 

sites are along the upper portions of the river, and it is likely that 

opportunities for high-head developments will be found beyond the 

limits of the survey. This portion of the river, however, is best 

reached from the east side of the range that is, by way of White 

Salmon River, Trout Creek, and the Indian Race Tracks. There are 

no trails along Lewis River above Muddy River. The river canyon 

is almost impassable in this portion, and no further progress could 

have been made without adding an unwarranted amount to the 

expense of the investigation.

Being glacier fed, the river is heavily loaded with glacial silt near 

the headwaters. This silt, however, gradually settles out, and in the 

lower reaches the water is comparatively clear. Muddy River, the 

most pronounced glacial tributary, is supplied from the glaciers on 

Mount St. Helens. Pine Creek is not a glacial stream, the water 

being largely supplied from ground storage in the lava beds through 

which it flows. Swift Creek, on the other hand, is glacial, and the 

waters are white with silt during warm weather.

LEWIS RIVER ABOVE MUDDY RIVER, NEAR COUGAR, WASH.

This station, which is located 1£ miles above the mouth of Muddy 

Kiver, 18 miles above Peterson's ranch and 23 miles above Cougar 

post office, was established August 8, 1909, to obtain data concerning 

low-water flow.

The gage is a vertical staff fastened to a vertical face of rock on the 

right bank. Measurements were made by wading, and no facilities 

have been provided for making measurements at high stages. On 

account of the isolation it was not possible to secure daily observations.

LEWIS RIVER AT PETERSON'S RANCH, NEAR COUGAR, WASH.

This station was established July 27, 1909. It is located 1,000 

feet above the mouth of Swift Creek, at the first riffle below a large 

outcrop of rock on the right bank, 2 miles above Peterson's ranch 

and 7 miles above Cougar post office, Wash. The gage is a vertical 

staff graduated to feet and tenths in two sections, the first 12 feet 

being attached to a point of the rock above mentioned. Measurements are made by use of a meter running on a small cable and operated from the bank. The river is crossed by means of a raft.

This station is intended as a permanent one, although facilities for 

making measurements at high stages have not yet been installed. 

It is maintained in cooperation with H. L. Gilbert, of Portland, 

Oreg.

LEWIS RIVER AT ARIEL, WASH.

This station was established July 7, 1909. It is located opposite 

Ariel post office, Wash., one-fourth mile above the mouth of George 

Creek. It was intended as a temporary station only, and no facilities were installed for making measurements at high stages. The 

gage is a vertical staff fixed to an alder stump on the right bank near 

the post office and store. Measurements were made either from a 

boat held in place by a small cable spanning the stream or by wading 

at a riffle 1,000 feet below the gage. Conditions at the station are 

not favorable for good results. The stream is used principally for 

floating logs. These logs lodging on the riffle in the vicinity of the 

station cause variable backwater conditions for which it is impossible to make correction.

MUDDY RIVER AT MOUTH, NEAR COUGAR, WASH.

This station was established August 6, 1909. The gage is a vertical staff located half a mile above the mouth of the river on the first
NORTH PACIFIC COAST. 473

riffle below a rocky gorge, 18 miles above Peterson's ranch and 23 

miles above Cougar post office, Wash. The station was established 

for temporary purposes only, to determine the low-water flow for 

1909, and no facilities were installed for making measurements at 

high stages. Measurements were made with a meter suspended from 

a small cable spanning the stream and operated from the river bank. 

The following discharge measurement was made by C. W. Harris:

August 6, 1909: Width, 87 feet; area, 149 square feet; gage height, 0.80 foot; discharge, 317 second-feet.

Gage height, in feet, of Muddy River at mouth, near Cougar, Wash., for 1909.

474 SURFACE WATER SUPPLY, 1909, PART XII.

PINE CREEK AT MOUTH, NEAR COUGAR, WASH.

This station was established August 4, 1909. The gage is a vertical staff on the left bank of the stream at the old camp grounds, 

about one-fourth mile above the mouth of the stream, near the 

quarter corner between sees. 23 and 24, T. 7 N., R. 6 E., about 13 

miles east from Cougar, Wash.

The station was established to determine low-water conditions 

during the summer season of 1909, and no permanent equipment 

was installed for making measurements at high stages. Measurements were made with a meter suspended from a light cable spanning 

the stream and operated from the bank. On account of remoteness 

from settlement continuous records of gage heights were not secured.

The following discharge measurement was made by C. W. Harris:

August 4, 1909: Width, 32 feet; area, 53 square feet; gage height, 1.00 foot; discharge, 142 second-feet.

Gage height, in feet, of Pine Creek at mouth, near Cougar, Wash., for 1909.

SWIFT CREEK AT MOUTH, NEAR COUGAR, WASH.

This station was established July 27, 1909. It is located 2 miles 

from Peterson's ranch, about 4^ miles east and 1 mile north of 

Cougar post office, Wash., one-fourth mile above the mouth of the 

stream, near the point where the north line of sec. 28, T. 7 N., R. 5 E. 

crosses Swift Creek. The gage is a vertical staff fixed to the right 

bank. Measurements are made from a foot log or by wading near 

the gage. As the station was established only to determine lowwater conditions during the summer season of 1909, no equipment 

was installed for making measurements at high stages.

The following discharge measurement was made by C. W. Harris:

July 27, 1909: Width, 49 feet; area, 78 square feet; gage height, 2.20 feet; discharge, 

179 second-feet.

Gage height, in feet, of Swift Creek at mouth, near Cougar, Wash., for 1909.

COWLITZ RIVER DRAINAGE BASIN.

TOUTLE EIVER BASIN.

DESCRIPTION.

Toutle River, the largest tributary of Cowlitz River, has its source 

in Spirit Lake, on the northwestern slope of Mount St. Helens, 

flows in a general westerly direction, and empties into Cowlitz River 

2 miles above Castle Rock, Wash. The total length of the river 

from the outlet of Spirit Lake to its junction with Cowlitz River is 

54.3 miles, and the total fall in that distance is 3,153 feet.

The principal tributaries, in their order downstream, are Cold 

Creek, Hoffstadt Creek, and Green River from the north and Alder 

Creek, South Fork, and Outlet Creek from the south.

The total drainage area is 510 square miles, distributed as follows:

NORTH PACIFIC COAST. 477

The prominent topographic feature of the area is Mount St. Helens. 

The elevation of this peak has not been accurately determined, but is 

given as between 9,750 and 10,000 feet. The general topography of 

the region is bold and rugged, somewhat similar to that of the adjoining basin of Lewis River. The area is probably the dissected and 

eroded remainder of a broad plateau that was modified by distorting 

uplifts and more or less covered with lava flows.

The country to the north and east of Mount St. Helens is included 

in the St. Helens mining district, and here the volcanic rooks are 

absent. The general formation in the mining district is syenite cut 

by porphyry dikes striking almost northwest and dipping 60° or 

70° W. Northwest of the syenite belt the country rock is mostly 

quartzite, broken and traversed by a series of almost perpendicular 

veins, whose general strike is northeast and southwest. Many of the 

veins of the district are of great width and carry sulphide ores, mostly 

of copper, iron, and lead. They are true fissure veins and are found 

along the contact between the porphyry dikes and the country rock. 1

The lands contiguous to the lower portion of the river are high and 

rolling but not rugged. Upstream these rolling lands are gradually 

replaced by narrower valleys and bench lands topped by bold peaks 

with scarred and eroded sides. - The river canyons, however, are 

not so abrupt as those of the other streams considered in this report, 

but the sides are of more uniform slope, with here and there a rocky 

bluff on one bank or the other. The stream flows on a bed of gravel 

and cobblestones through almost its entire length, with scattered 

ledges of partly exposed bedrock dipping steeply into the gravel bed 

of the river. This indicates that the river canyons at one time were 

deeper but that they have been filled by water-deposited gravel and 

talus from the canyon sides.

Only a small portion of this area lies within the Columbia National 

Forest. The west line of T. 5 N. is the western boundary of this 

forest, but practically all tracts along the river within it are patented 

lands.

The average stand of timber on the area is probably 10,000 feet 

b. m. per acre except where it has been logged off. The timber from 

the easily accessible tracts has been partly removed, but the greater 

portion of the timber in the basin is still in its virgin state. Most of 

the logged-off areas are being restocked and all is covered with young 

growth and underbrush except where the lands have been cleared for 

agriculture.

. The species found are those common to the western slope of the 

Cascade Range. Red or yellow fir constitutes about 50 per cent of 

the stand, cedar about 10 per cent, hemlock 5 per cent, and white fir

Ann. Kept. Washington Geol. Survey for 1901, vol. 1, pt. 2 -
478 SURFACE WATER SUPPLY, 1909, PART XII.

5 per cent, with considerable quantities of Noble fir, mountain hemlock, and Englemann spruce. The rivers are lined with dogwood, 

alders, and maple, and over all there is a dense undergrowth of vines, 

brambles, ferns, and deciduous shrubs.

The Seattle and Portland line of the Northern Pacific Kailway 

crosses the river near its mouth, but elsewhere there are no railroads 

in the area. There is a wagon road from Castle Rock to Spirit Lake, 

and from it roads and trails lead in various directions. A trail follows Green River to the St. Helens mining district. The lower 

portion of the drainage area is well provided with wagon roads. 

Roads lead from Castle Rock to Silver Lake and Sightly and to points 

on South Fork and the rolling lands between that stream and Cowlitz River.

The first discoveries of metalliferous ores in the mining district 

were made in 1891 and the district was formed September 22, 1892. 

At the present time there is considerable activity in this region, and 

there is every indication that if transportation facilities were provided some valuable mining property would be developed here. The 

mines and proposed transportation lines to them should afford a 

good market for water power.

Agriculture plays no small part in this region. All along the river 

and on the rolling lands nearer the mouth many tracts have been 

cleared for diversified farming or planted to orchards. The soil is 

rich and the climate is favorable for fruit raising and other forms of 

intensive agriculture. Hay and grains are plentiful along the shores 

of Silver Lake, and garden vegetables, potatoes, and small fruits and 

berries are raised in abundance wherever the attempt has been made.

Lumbering, however, has been and probably will continue for 

some years to be the principal industry. Several small shingle and 

lumber miUs are in operation, but the greater portion of the logs are 

transported to the larger mills on lower Cowlitz and Columbia rivers.

At present there are no developed water powers in the drainage 

area, but near the outlet of Spirit Lake some power rights have reached 

the point of preliminary construction of crib dams and diverting 

flumes. The properties are claimed by adverse interests, so that all 

work has been stopped by injunction and the respective rights are 

in litigation.

Spirit Lake, at the head of the main stream, has a total drainage 

area of 12 square miles and a normal surface area of 2.2 square miles. 

About 80,000 acre-feet could be developed by raising the water 

surface 50 feet. This is equivalent to a uniform flow of 200 secondfeet for 200 days. There is no doubt that this reservoir would be 

filled each winter season. Silver Lake (or Toutle Lake, as it is 

sometimes called), in the lower portion of the area, has a drainage
NORTH PACIFIC COAST. 479

area of 42 square miles and a surface area of 5.1 square miles. Its 

water surface could not be raised very much, but it is probable that 

50,000 acre-feet could be stored. The run-off from the drainage 

area, however, is relatively small, and Outlet Creek, which joins it to 

the trunk stream, is usually dry in summer.

Toutle Fiver is a glacial stream. The summer flow is largely 

supplied by the glaciers on the northern slope of Mount St. Helens. 

The waters from these glaciers do not flow into Spirit Lake, but reach 

the main stream through three tributaries from the south. Some 

water from the glaciers on the west side of the mountain flows into 

South Fork, but the contribution to that stream from this source 

is smaU. Green River is not fed by glaciers but receives its waters 

from surface drainage and ground storage during the summer. Its 

headwaters reach into the high spurs of the main range and it doubtless draws from snow banks that remain well into the summer.

During the summer of 1909 the United States Geological Survey 

made a water-power survey of this basin.1 Discharge measurements 

were made on aU the important tributaries and on the main stream 

at various points to determine the summer flow. The stream-flow 

data obtained during this investigation are included in this present 

report.

Toutle River has an average fall, in the 54.3 miles from Spirit 

Lake to its mouth, of 58.1 feet to the mile. The fall in the upper 10 

miles averages 137 feet and in the lower 10 miles 19 feet to the mile. 

Green River, at the mouth, has an average fall of 20.8 feet to the 

mile, but the faU increases rapidly as the stream is ascended. South 

Fork, at its mouth, has an average fall of 19.2 feet to the mile, but the 

grade does not increase greatly until near the spurs of Mount St. 

Helens.

Although the stream in general flows on a gravel bed, there are 

many favorable localities for diversion of the water into open canals 

or pressure pipes. The sides of the canyon and the benches along 

the river afford opportunities for canal construction.

TOUTLE RIVER AT ST. HELENS, WASH.

This station was established September 11, 1909. It is located 

at the county bridge across Toutle River at St. Helens, Wash., in 

the SE. I sec. 15, T. 10 N., R. 2 E., above the mouth of Alder Creek. 

It is 4 miles above the mouth of Green River and one-fourth mile 

from St. Helens post office, Wash. The gage is a vertical staff 

10 feet long, graduated to feet and tenths, and fixed to the down1 For the results of this investigation, including profiles of the river surveyed, see Stevens, J. C., Water

TOUTLE EIVER NEAR CASTLE ROCK, WASH.1

This station was established September 4, 1909. The gage is 

located at the downstream end of a large rock on the left bank near 

the quarter corner between sees. 12 and 13, T. 10, R. 1 W.,2 about 

1| miles southeast from Tower, Wash., and about 2£ miles below the 

South Fork of Toutle River and Outlet Creek. The station was 

established in conjunction with several others in this drainage basin 

for the study of low-water conditions on this stream.

!This station was called "near Tower" in Water-Supply Paper 253. 

2 R. 1 E., as given in Water-Supply Paper 253, is an error.

PUGET SOUND DRAINAGE BASIN. 

DESCRIPTION.

The drainage of the western slope of the Cascade Mountains in 

Washington is into Puget Sound. The most important streams are 

the Nisqually, which drains the southern portion of Mount Rainier; 

the Puyallup, draining the northern and western portion of Mount' 

Rainier; White River, which drains the northern\and;eastern portion 

of Mount Rainier; Green River, the canyon of which is occupied by 

the Northern Pacific Railway; Cedar River, from which the city of 

Seattle draws its water supply; Snoqualmie River; Skykomish River, - 

whose canyon is occupied by the Great Northern Railway; Stila84547° WSP 272 11 *-31
482 SURFACE WATER SUPPLY, 1909, PAET XII.

guamish River; and Skagit River, which drains the territory between 

Mount Baker and the main summit of the Cascade Range.

Comparatively little is known concerning the run-off and other 

hydrographic characteristics of these streams. They are capable of 

furnishing great quantities of water power, as the fall is great, and 

the flow generally well sustained during the summer months. The 

area is perhaps one of the most densely forested sections of the United 

States, a large portion of the headwaters of all the streams being 

included within the boundaries of national forests.

The mean annual rainfall of this area varies greatly from point to 

point. Puget Sound has long been noted for its excessive rainfall, 

yet in the very midst of this area of abundant precipitation is found 

a small section that is almost semiarid. The mean annual rainfall at 

Olympia is 55 inches, at Tacoma 47, at Seattle 36. West of Seattle, 

on Hood Canal, the precipitation is 76 inches per annum, while 35 

miles to the north, at Port Townsend, the precipitation is only 21 

inches. Across Admiralty Strait from Port Townsend the rainfall is 

23 inches. The country adjacent to Port Townsend lies to the 

northeast of the Olympic Mountains in the path of the prevailing 

winds of the southwest, but the winds are deprived of a large part of 

their moisture before Port Townsend is reached. Northeastward the 

precipitation gradually increases again, and at Marblemount it is 47 

inches per annum. The only reliable records of precipitation near 

the summit of the Cascades have been obtained at Snoqualmie Falls, 

where, at an elevation of 438 feet, the precipitation is 60 inches. It is 

probable that on the summit of the Cascades the annual precipitation 

is 120 inches or more. A large part of the precipitation in this portion 

of the country falls during the nine months from September to May. 

On the summit of the Cascades it is mostly snowfall. Snow deposits 

during a single winter frequently aggregate 40 feet or more. When 

these snows disappear in the spring, high waters may be expected in all 

streams draining these mountains. The regular spring run-off, however, is rarely high enough to do a great amount of damage, as the 

streams are very steep and carry the water away rapidly. Climatic 

influences, however, frequently combine to cause very destructive 

floods. These usually occur in the fall after the first heavy snowfall, 

and are caused by chinook winds from the southwest when accompanied by rain. These winds are annual occurrences, but only when 

they follow a heavy precipitation of early snow do they cause damaging floods.

The only complete records of run-off are those obtained on Cedar 

River. From these records it appears that the year 1905 was an 

exceptionally low year as far as run-off was concerned, and 1903 a 

wet year.
NORTH PACIFIC COAST. 483

CEDAR RIVER NEAR RAVENSDALE, WASH.

This station was established September 27, 1902.. It is located at 

the intake of the pipe line which furnishes water to the city of Seattle. 

It is 15 miles below Clear Lake and 3 miles north of Raveflsdale.

The data obta'ined at this station are of great value, as they are 

continuous and reliable and constitute practically the only streamflow data on the western slope of the Cascade Range in Washington. 

The flow is obtained from the formula Q=3.75LH3/2 + 35. The gage 

heights represent the head of water (H) on the crest of the dam. 

The length of the crest (L) is 120 feet. The crest is steel shod and 

of triangular section. The upstream slope forms an angle of 30° 

with the horizontal and the downstream slope an angle of 60°. F,or 

this dam a mean of the coefficient obtained from the current-meter 

measurements made from 1902 to 1906 gives a value of c=3.76, 

while the mean obtained from a set of weir experiments for a dam 

of similar type is approximately 3.73. (See Water-Supply Paper 

200, PI. X, series 140.) In computing the rating table c has been 

given the value of 3.75. The quantity 35 is added as the amount 

diverted into the pipe line. . This diversion varies within small limits, 

but 35 second-feet has been used throughout in computing the run-off 

for this area. (For a description of the measurement of the amount 

diverted see Trans. Am. S'oc. Civil Eng., vol. 49, p. 112.) The datum 

of the gage was set to coincide with the crest of the dam at an elevation of 436 feet above sea level. The gage had not been checked for 

several years until April, 1911, when it was found to read 0.11 foot 

too high. It is not known when the change occurred, so 1909 gage 

heights have not been corrected. The amount of water diverted in 

the pipe lines has also been somewhat greater than 35 second-feet 

since the completion in 1909 of the new pipe line with a capacity of 

70 second-feet.

No current-meter measurements were made during 1909.

SKAGIT RIVER NEAR MARBLEMOTJNT, WASH.

This station was established December 21, 1908, and is maintained 

in cooperation with the Skagit Power Co. The station is located 

800 feet above the point known as the "Corner," at the mouth of the 

canyon, about 1 mile above the mouth of Goodell Creek and about 

26 miles above Kockport, the nearest railway station. The river is 

subject to enormous floods that do a great deal of damage in the 

lower portions of the stream, and any attempt to remedy the conditions will require a thorough knowledge of the discharge of the river.

The gage is a vertical staff on the right bank in the measuring section. Measurements are made from a cable and car. The banks of 

the stream are high and rocky and will not overflow. The bed is 

composed of granite bowlders and is very rough, although in the 

immediate section where measurements are made the river flows 

quite smoothly.

CASCADE RIVER NEAR MARBLEMOUNT, WASH.

This station was established March 8, 1908, by the Skagit Power 

Co., which installed the equipment and furnishes gage readings and 

most of the discharge measurements. It is located 8 miles above the
488 SURFACE WATER SUPPLY, 1909, PART XII.

mouth of Cascade River and the same distance above Marblemount, 

Wash. It is at a proposed site for a dam and power plant. Above 

this point the river grade is comparatively flat and considerable 

storage can be developed here.

Three gages have been read, as follows: Gage No. 1 at a foot log 

below the camp of the power company. This gage was used from 

March 8 to March 31, 1909. Gage No. 2 was installed April 1, 1909, 

about 6 miles downstream and set to read the same as No. 1. As the 

river grade is very flat they are assumed to read the same at all stages. 

It was in use from April 1 to May 24, 1909. Gage No. 3 was put in 

May 25, 1909, and used the rest of the year. It is 500 feet above the 

location of No. 1, which had washed out. On June 1,1909, the station 

was moved to gage No. 3. Rating curves have been developed for 

the three gages. Gage No. 3 is a vertical staff on the right bank 100 

feet upstream from the cable from which measurements are made. 

The channel in the vicinity of the station is straight; the banks are 

too high to overflow. The bed of the stream is of gravel and cobblestones and' permanent except during extreme high water. The 

water at all stages is comparatively swift and the bed is rough. On 

this account it is necessary to obtain a relatively large number of 

measurements, as the individual errors of each measurement are comparatively large.
