SURFACE WATER SUPPLY OF THE NORTH PACIFIC

COAST, 1907-8.

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:

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

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 to that which can be provided with 

the appropriations available. The field covered and the character 

of the work are believed to be the best that could be accomplished 

under the controlling conditions. It would undoubtedly be of more 

scientific importance and ultimately of more practical value if the 

money now applied to wide areas were concentrated on a few small 

basins. 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 maintained during a period of years sufficient to cover all stages, in order that within 

reasonable limits the entire range of flow from the absolute maximum 

to the absolute minimum may be determined. The length of such a 

period manifestly varies for different streams and can not be absolutely determined. Experience has shown that the records should 

cover from five to ten years, or for some streams twenty years or 

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 the Geological Survey endeavors 

to approach as nearly as possible the highest degree of precision 

which a rational expenditure of time and a judicious expenditure of 

a small amount of money will allow. In all engineering work there 

is a point of refinement beyond which it is needless and wasteful to 

proceed, and this principle applies with especial force to stream-flow 

measurements. It is confidently believed that with some unavoidable exceptions the stream-flow data presented in the publications of 

the Survey are 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 

many stations. All persons are cautioned to exercise the greatest 

care in the utilization of such incomplete records.

Kecords of varying lengths have been obtained at about 1,400 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 1907 and 1908 regular 

gaging stations were maintained by the Survey and cooperating 

organizations at about 740 points in the United States, and in addition numerous miscellaneous measurements were made. Data were 

also obtained in regard to precipitation, evaporation, storage reservoirs, river profiles, and water power in many sections of the country.
INTRODUCTION. 11

These data will be made available in the regular surface water-supply 

papers and in special papers from time to time.

PURPOSES OF THE WORK.

Among the purposes for which the results contained in this volume 

are requisite are navigation, irrigation, domestic water supply, water 

power, swamp and overflow land drainage, and flood prevention. 

The demands of all these interests are immediate.

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 $42,000,000 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 is based absolutely on the amount of water 

available. Therefore investigations of stream flow in that portion 

of the country are of first importance in the redemption of the lands, 

as well as constituting an insurance of federal and private investments.

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

supply, and while the federal interest in this aspect of the matter 

is less direct than in the aspects already named, this use of water 

nevertheless has so broad a significance with respect to the general 

welfare that the Federal Government is ultimately and intimately 

concerned.

Water power. The time is rapidly approaching when the development of the water power of the country will be an economic necessity. 

Our stock of coal is being rapidly depleted and the cost of steam 

power is increasing accordingly. Industry will cease its growth if 

cheap power is not available, and in that event the United States as a 

nation will cease to progress. Water power is the only avenue now 

open. When the electric transmission of power was accomplished, the 

relation of our water powers to national economy changed entirely. 

Previous to the day of electric transmission the importance of a water 

power was largely confined to 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 is dependent 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 condi-
12 SURFACE WATER SUPPLY, 1907-8.

tions. 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 

drainage of a large area into any particular channel, that channel 

becomes so gorged with water that overflow conditions are created in 

places not previously 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 

exceeds $100,000,000 annually and in the year 1908 the aggregate 

damage, based on reliable data, 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 

has 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 States has been 

divided into twelve parts, whose boundaries coincide with certain 

natural drainage lines. The areas so described are indicated by the 

following list of papers on surface water supply for 1907 and 1908. 

The dividing line between the North Atlantic and South Atlantic 

drainage areas lies between York and James rivers.

NOTE. No data regarding stream flow are given in the 15th and 17th annual reports.

The records at most of the stations discussed in these reports 

extend over a series of years. An index of the reports containing 

records prior to 1904 has been published in Water-Supply Paper 119. 

The first table which follows gives, by years and drainage basins, the 

numbers of the papers on surface water supply published from 1899 

to 1908. Wherever the data for a drainage basin appear in two 

papers the number of one is placed in parentheses and the portion of 

the basin covered by that paper is indicated in the second table. For 

example, in 1904 the data for Missouri River were published in WaterSupply Papers 130 and 131, and the portion of the records contained 

in Water-Supply Paper 131, as indicated by the second table, is that 

relating to Platte and Kansas rivers.

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

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

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 follows:

"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 others 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 in inches" 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.

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

required to cover an acre to the 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, rating 

table, table of monthly and yearly discharges, and run-off. For 

stations located at weirs or dams the gage-height and rating tables 

are omitted and a table of daily discharge is substituted. For 

stations where the flow is computed by shifting-channel methods, a 

table of daily discharge is given in place of rating tables, which are 

not used in these methods of computation.

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 full information regarding 

diversions which decrease the total flow at the measuring section. 

Statements are also made regarding the accuracy and reliability 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 correction to 

the gage heights is 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. 

11947 10 2
18 SURFACE WATER SUPPLY, 1907-8.

The discharge measurements and gage heights are the base data 

from which the rating 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 published 

to enable engineers to determine the daily discharge by its application to the table of gage heights or to check results in the table 

of monthly discharge.

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 period when the 

water surface was at crest height and the corresponding discharge 

consequently larger than given in this 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 15, 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 formulas; (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.

Slope method. Much information has been collected relative to the 

coefficients to be used in the Chezy formula, v = c -s/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 in 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 the method the 

reader is referred to the various text-books 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
INTRODUCTION. 19

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, crest 

which is not level, 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 dams 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.

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 a) 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 editions of both of these water-supply 

papers are practically exhausted. They can, however, be consulted 

at most of the larger libraries of the country or they can be obtained 

from the Superintendent of Documents, Washington, D. C., at a cost 

of 20 cents for No. 180 and 35 cents for No. 200. Remittances must 

be made by postal money order, express order, or New York draft.

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;

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

a variation of more than about 5 per cent in 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

« Water-Supply Paper 200 Is a revision of No. 150, the edition of which is exhausted,
20 SUKFACE WATEK SUPPLY, 1907-8.

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, B.) 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 at the 

time of measurement.

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. (For a discussion of methods of computing 

the discharge of a stream see Engineering News, June 25,1908.)

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 d6bris 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. For further information regarding 

this method the reader is referred to Water-Supply Paper 95 and to 

the various text-books covering the general subject of stream flow.

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. Plate 

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

equipped for measurements at bridge and cable stations. On the 

sides the same type of meter is shown equipped for wading measurements to record by the acoustic method on the left and by the electric 

method on the right. 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 number of revolutions is 

indicated electrically. The rating, or 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. 

(See PI. I, A.) From these data a rating table is prepared which
22 SURFACE WATEE SUPPLY, 1907-8.

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, B.) 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

PRICE PENTA-RECORDING CURRENT METERS.
INTRODUCTION. 23

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. For information in regard to flow under ice cover, see 

Water-Supply Paper 187.

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
24 SUBFACE WATEE SUPPLY, 1907-8.

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. 19.) 

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.

For every published rating table the following assumptions are 

made for the period of application of the table: (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. 

For illustrative example of a station of this type see Water-Supply 

Paper 241 and Plate IV.

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
INTRODUCTION. 25

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. For illustrative example of a 

station of this type see Water-Supply Paper 246.

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. 

The 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 their 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 the channel caused by cut, or fill, or both, at and 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
26 SURFACE WATER SUPPLY, 1907-8.

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

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

rarely exist.

(6) 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 controlling 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. For illustration of a station of this class see Water-Supply Paper 242, page 23.

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
INTKODUCTION. 27

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. For illustrative 

example of a station of this type, showing the Bolster method of 

determining the daily discharge graphically, see Water-Supply 

Papers 247 and 249.

The computations have, as a rule, been carried to 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 monthly discharge 

tables.

For most of the northern stations estimates have been made of 

the monthly discharge during frozen periods. These are based on 

measurements under ice conditions wherever 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 

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
28 SURFACE WATER SUPPLY, 1907-8.

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 prevail.

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.

In order to give engineers and others information regarding the 

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

rating tables and an accuracy column is inserted in the monthly discharge table. In 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, the 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, but 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 in 

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

year nearly always throw new light on data already collected and
INTRODUCTION. 29

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. This is particularly true of the maximum and minimum 

figures, which in the very nature of the method of collecting these 

data are liable to large errors. The maximum value should be 

increased considerably for many stations in considering designs for 

spillways, and the minimum value should be considered for a group 

of, say, seven days and not for one day.

The rating table, provided the engineer accepts it, is published 

primarily to allow him to apply it directly to the daily gage heights 

and rearrange the daily discharges in order of magnitude or by some 

other method.

COOPERATION AND ACKNOWLEDGMENTS.

The work in Oregon has been done in cooperation with the State. 

The legislature of 1905 passed an act providing an annual appropriation of $2,500 contingent upon the United States Geological Survey 

allotting an equal amount to be expended within the State for the 

investigation of its water resources.

The act of 1905 makes the state engineer the agent of the State in 

this cooperation, and each year a contract is entered into between the 

state engineer and the Director of the Geological Survey. The principal features of the contract are as follows:

1. The United States Geological Survey retains direct supervision 

of the field work and the preparation of the data for publication.

2. All the material collected field notes, maps, etc. are open at 

any time to the inspection of the state engineer, and if they are not 

entirely satisfactory the agreement can be terminated at any time.

3. The salaries of classified employees and cost of nonexpendable 

equipment is paid from the government fund, while traveling 

expenses, salary and expenses of field assistants, and cost of expendable supplies are paid from the state fund. 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.
30 SURFACE WATER SUPPLY, 1907-8.

To secure efficiency, no better scheme than cooperative investigations of this nature can be devised. The State is the chief beneficiary, 

for its interest in procuring a thorough knowledge of its resources is 

paramount. At a very moderate cost for field work it can take advantage of an organization already trained in the collection of the data 

and obtain the published results without additional expense.

Unfortunately the amount appropriated by the State is altogether inadequate to satisfy the demand for water-supply data. 

The United States Geological Survey, therefore, has found it necessary to expend more than treble the amount required to meet the 

State's appropriation. The United States Reclamation Service, 

which is perhaps the heaviest investor in the development of the 

State's resources, has been so handicapped in its work for lack of 

water-supply data that it has expended from its own fund considerable money for investigations of this nature. Interbureau agreements 

have been reached whereby the greater part of the work for the 

Reclamation Service is carried on by the Geological Survey through 

its organized force, and the actual cost thereof refunded. For the 

calendar year 1908 there has been expended by the Geological Survey from government and state funds a total of $10,810.79, distributed 

as follows:

ROGUE RIVER DRAINAGE BASIN.

DESCRIPTION.

Rogue River drains the southwestern corner of the State of Oregon, 

its basin extending from the extreme western part of Klamath 

County across Jackson and Josephine counties, and including the 

northern half of Curry County. On its north are the Rogue River 

Mountains and on the east are the Cascades, while in the southern 

part of the area is a spur of the Siskiyou Mountains. In all the basin 

comprises 5,080 square miles.
32 SURFACE WATER SUPPLY, 1907-8.

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 the Rogue 

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, 

and its principal tributaries are from the south, as is shown by the 

following table:

Principal tributaries of Rogue River.

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

North Fork. Middle Fork.

Elk Creek. South Fork.

Stewart Creek. Big Butte Creek (drainage area, 268

Evans Creek. square miles).

Leland Creek. Little Butte Creek (drainage area, 361

square miles). 

Bear Creek (Stewart 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 Lake, which lies to the east in the center of Crater Lake Natural 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 a nor any other reaching the surface within a few 

miles. The walls inclosing the lake are made up of alternating 

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

and are so porous as to afford an easy passage for much water. 

Springs are abundant and remarkable in size. Little and Big Butte 

creeks drain the southern portion of the Cascade Forest Reserve. 

Bear Creek, formerly called Stewart Creek, drains the famous fruit 

section of Rogue River valley; Applegate Creek drains the Siskiyou 

Mountains; and Illinois River the territory to the south of the main 

stream near the coast.

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 completely timbered, but the stand is not so 

heavy as on the area to the north drained by Umpqua River, as the

oDiller, J. S., Geology of Crater Lake Natural Park: Prof. Paper U. S. Geol. Survey No. 3,1902, p. 60.
KOGTJE KIVEB DRAINAGE BASIN. 33

precipitation is lighter. 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. At the headwaters 

of the stream the greater part of the precipitation is rainfall during 

the winter months. As is usual in regions where the precipitation 

is sufficient for the production of crops without irrigation, development along this line is inconsiderable. 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, however, 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 qualit}r of apples, pears, and other fruits raised there.

The streams of this area, like others draining the Cascade Mountains, afford wonderful possibilities for water-power development. At 

present the only important plants are those of the Rogue River Electric Company at Gold Ray and at Prospect.

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

For the three and half 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.

The following gaging stations have been maintained in this river 

basin:

Rogue River near Tolo (1905 to 1908).

North Fork of Rogue River at Prospect (1907 and 1908).

Little Butte Creek near Eagle Point (1907 and 1908).

Bear Creek at Talent (1907 and 1908).

Applegate Creek at Murphy (1907 and 1908).

Rogue River near Galice (1907).

NORTH FORK OF ROGUE RIVER AT PROSPECT, OREG.

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

River Electric Company's dam one-half mile above Prospect, 5 miles 

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

River gorge.

The fall of the river through this gorge is to be utilized by the 

company 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.

34 SUEFACE WATER SUPPLY, 1907-8.

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. The gage located above the dam was 

read daily from July 17 to October 10, 1907, and once or twice a 

week during the first half of 1908, but the daily ratings during 1908 

were made on an auxiliary gage at the observer's house. No estimates of flow are possible with the data at hand, but it is hoped 

that a permanent rating curve can later be developed to which these 

records of gage heights can be applied.

ROGUE RIVER NEAR TOLO, OREG.

This station was established August 30, 1905. It is located at 

Gold Ray, the site of the Rogue River Electric Company's power 

plant, 1^ miles below Tolo and just below the mouth of Bear Creek.

The data obtained at this station have great value in connection 

with the use of the river for water-power development and its proposed use for extensive irrigation works, a number of large ditches 

being already under construction.

The station is located below the tail race of the power plant, at 

which a dam about 20 feet high forms a large forebay. (See PL III, 

.A.) The flow at the station is, therefore, irregular, depending upon 

the amount of water used through the turbines. The velocity of the 

water at the gaging station is quite swift, and the channel is not 

stable. 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.

LITTLE BUTTE 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.

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 represent the 

natural run-off from the drainage area. The data are insufficient 

for an estimate of extreme values.

This stream is already used to a large extent for irrigation and 

additional developments are under way. It also furnishes municipal 

water supply for the city of Medford.

BEAR CREEK AT TALENT, OEEG.

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

380 square miles.

The gaging station was established July 11, 1907, at a highway 

bridge at Talent, 500 feet above the head of a power and irrigation
ROGUE EIVEE DRAINAGE BASIN. 41

canal which diverts water from the left bank, about one-half mile 

below the mouth of Wagner Creek and 1^ miles above the mouth of 

Anderson Creek.

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 exceptionally favorable for good results. 

The bed of the stream is somewhat changeable and a new rating curve 

will have to be developed after each flood.

APPLEGATE CREEK AT MURPHY, OREG.

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 measures 606 square miles.

This station was established July 22,1907. It is located at Murphy, 

8 miles above the mouth of the creek and 7 miles from Grants Pass.

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 dam a short distance below, and as this dam is a temporary affair, 

made of brush, it is washed away, either wholly or in part, with every 

rise in the creek, even during irrigating seasons. For this reason it 

was necessary during 1907 and 1908 to develop four rating curves, and 

to interpolate a part of the records.

UMPQUA RIVER DRAINAGE BASIN. 

DESCRIPTION.

Umpqua River is formed by the junction of its North and South 

forks near the city of Roseburg in Douglas County, Oreg. The 

North Fork rises in Diamond Lake on the summit of the Cascade 

Mountains at an elevation of 5,300 feet and pursues a westward 

course. The South Fork is also formed by two forks the northern 

rising in old Bailey Mountain about 4 miles south of Diamond Lake, 

and the southern on the northern slope of Abbot Butte, and the 

united waters flow westward and northward. From the junction of 

its principal forks, the Umpqua takes a tortuous but in general 

northerly course to Elkton, beyond which its course is more nearly 

westward until it debouches into the Pacific at Winchester Bay in 

the northwestern part of Douglas County. Its total drainage area 

comprises about 4; 000 square miles. At Scottsburg, just above 

tide water, 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, draining the 

divide between the Umpqua and Willamette basins; Cow Creek, 

which drains the divide between Rogue River and the Umpqua 

drainage; and the North and South forks.

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

comparative 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, it is 48 

inches. The mouth of the stream probably receives as much as 60 

inches of this 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 may be found on the smaller creeks of
48 SUEFACE WATER SUPPLY, 1907-8.

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 possibilities for waterpower development in this area are almost 

phenomenal, there are no plants of importance.

There is a remarkable difference between the run-off of the North 

and South forks of the Umpqua which would have been very difficult to detect except through actual records of stream flow. The 

annual run-off of the North Fork is 4 second-feet per square mile 

while that of the South Fork is 1.6 second-feet per square mile. Since 

records have been kept, highest run-off values were shown in 1907. 

It is probable that 1905 was a year of low run-off, although the 

records do not cover that period.

The following gaging stations have been maintained in this drainage 

basin:

Umpqua River near Elkton (1906 to 1908).

North Fork of Umpqua River near Oak Creek and Winchester (1905 to 1908).

South Fork of Umpqua River near Brockway (1905 to 1908).

Mill Creek near Ash (1907 to 1908).

SOUTH FOEK OF UMPQUA EIVEE NEAE BEOCKWAY, OEEG.

This station was established December 6, 1905. It is located just 

below Winston's bridge, 6 miles south of Roseburg, 3 miles below the 

mouth of Lookingglass Creek, 10 miles below the mouth of Myrtle 

Creek, and 7 miles above the junction of the North and South forks 

of the Umpqua. Measurements were originally made from a cable, 

but this was destroyed by flood January 4, 1907, and since that date 

measurements have been made from the highway bridge. The datum 

of the gage has not been changed since it was established.

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

a permanent rating curve has been established. The ice conditions 

during the winter months do not cause interference, and the records 

are believed to be reliable.

The data obtained are of particular interest in studying the run-off 

conditions from forested areas under a high rainfall.

UMPQUA RIVER NEAR ELKTON, OREG.

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

Portland, through whose courtesy the gage heights are made available. It is located at Smiths Ferry at the falls in the river 4 miles
UMPQUA EIVER DRAINAGE BASIN. 51

above Elkton. No tributaries of importance 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 a high rainfall.

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.

a Gage height recorded as 0.0 November 2 to 19; it was probably lower than this November 5 to 18; discharge for 9 to 18 estimated at 1,150 second-feet.

6 Gage readings of 0.0 accepted, although the river probably went a little lower in early part of September.

c Gage heights of 0.0 have been accepted, although the river probably went somewhat lower in October.

d Discharges for August 11 to October 12 have not been computed, as the river was probably below the 

zero of the gage most of the time.

NOTE. Owing to poor gage readings, the monthly discharges are liable to very large errors at low stages.

NORTH FORK OF UMPQUA RIVER NEAR OAKCREEK AND WINCHESTER,

OREG.

This station was established September 6, 1905, at Dixon's farmhouse, 3 miles west of Oakcreek, 10 miles below the mouth of 

East Fork of North Fork, and 9 miles northeast of Roseburg. The 

observer moved away October 10, 1908, and on November 10 the 

station was moved to Winchester, at the Southern Pacific Railroad bridge, about 6 miles north of Roseburg and 6 miles above the
54 SURFACE WATER SUPPLY, 1907-8.

mouth of the stream. As no important tributaries enter between 

the old and new positions, the records are comparable.

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 South Fork afford some very interesting information concerning the run-off from forested areas.

The following measurement was made November 10, 1908: Width, 

216 feet; area, 861 square feet; gage height, 1.86 feet; discharge, 

1,270 second-feet.

Daily gage height, in feet, of North Fork of Umpqua River near Oakcreek, Oreg.,for 1907.

a Discharges interpolated June 22 to 30.

MILL CREEK NEAR ASH, OREG.

This station was established May 29/1907. It is located at the outlet of Loon Lake, in the lower Umpqua River drainage area. Measurements are made by wading just below the outlet of the lake, and the
tTMPQTJA RIVER DRAINAGE BASIN. 57

gage heights used in determining the discharge are those observed 

in the lake on the south shore, one-half mile above the outlet.

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. The gage heights 

have been furnished by J. G. Kelley, of Portland.

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 River Bay, about 6 miles northwest 

of Kernville. Its total length is approximately 50 miles, and its 

drainage area measures about 320 square miles.

Its 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 show very little variation in 

the total run-off of this drainage area, but it is probable that 1905 

would be classed as a dry year, while 1906 may safely be considered 

a wet year.

Only one station has been maintained in this basin that at 

Siletz (1905 to 1908).

SILETZ RIVER AT SILETZ, OREG.

This station, which was established November 25, 1905, is located 

at Siletz Ferry, 9 miles north of Toledo, 6 miles below the mouth of 

Rock Creek.
SILETZ EIVER DRAINAGE BASIN. 59

The data obtained at this station 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 gage datum has not been changed since the gage was established, and the records for the medium and low stages are reliable. 

The stream is subject to sudden and violent floods, but as the station 

is somewhat inaccessible, it has been impossible up to the present 

time to obtain measurements during flood periods. The estimates 

for such periods have, therefore, been made by an extension of the 

discharge curve, a method which appears to be legitimate, as the 

stream is entirely confined within its banks at the gaging section.

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 

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
62 SURFACE WATER SUPPLY, 1907-8.

southerly direction, it turns westward and forms the boundary lines 

between Washington and Oregon, and empties into 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:

Square miles.

Washington.................................................. 48, 000

Idaho....................................................... 81, 380

Montana.................................................... 25, 000

> Nevada...................................................... 5, 280

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

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

This area is limited on the west 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 table 

lands. 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 (14,380 feet), Mount Adams (12,307 feet), Mount 

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

The principal tributaries of the Columbia River from source to 

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:

a Parts of the Columbia and its tributaries marked with asterisk are navigable under favorable conditions. 

Practically all these stretches of river can be made navigable at all seasons of the year at comparatively small 

expense. The Columbia and Snake Rivers were formerly navigated throughout the year, except during 

occasional blockades from ice, from Celilo to Lewiston. It will be noted that part of Snake River,, from, 

mouth to Riparia, is now marked "navigable under favorable conditions."

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. In 1907 the Columbia 

bar had a navigable depth of approximately 26 feet at low tide; 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 1906 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 ra 

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 sixty-five years and large areas have been 

cleared, the percentage of forested area to the entire area has been 

reduced but slightly. It is believed that at least 45 per cent (about 

11,600 square miles) of the drainage area of Columbia River is forested, 

and that about 5,800 square miles contain merchantable timber.

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 to 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 Cascade Range, however, ice conditions during the winter months 

are not encountered.
COLUMBIA EIVEE DRAINAGE BASIN. 65

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 irrigation, the area ranges from the extremely arid 

region, where irrigation is absolutely essential, through the semi-arid 

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 

brought under irrigation 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 250,000 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 the Columbia River occurred in June, 

1894. The highest floods on the tributaries of this river are invariably caused by "chinook" a warm wind, usually accompanied by 

rain, occurring in the spring and fall. The fall "chinook" usually 

brings the highest waters, since it may occur immediately after a 

heavy snow has covered the mountain ranges. The Columbia itself 

is not greatly affected at such times.

COLUMBIA RIVER NEAR PASCO, WASH.

This station was established October 15, 1904. It is located at the 

Northern Pacific Railway bridge near Pasco, 4 miles above the mouth 

of Snake River and 7 miles below the mouth of Yakima River. Only 

one current-meter measurement has been made at this station. The 

gage heights, however, are complete, and it is hoped that future 

measurements will develop a rating curve to which these can be applied. Since September 1, 1908, the records have been furnished 

by the United States Weather Bureau. The datum of the gage is 

307.75 feet above sea level.

COLUMBIA EIVER AT THE DALLES, OREG.

This station is located at The Dalles, below the mouth of Deschutes 

River and above Hood and Klickitat rivers. Records of gage heights 

have been kept at this point by the Weather Bureau since 1892. A 

number of measurements were made in 1903 by the United States 

Engineer Corps. In 1907 and 1908 measurements were made by 

the Geological Survey, and these in connection with the earlier measurements fully develop the discharge curve. (See PI. IV.)

A comparison has also been made between the gage readings at 

The Dalles and those taken at Cascade Locks, 20 miles down the
68 SURFACE WATER SUPPLY, 1907-8.

river. At the lower point the gage records are nearly complete for 

thirty years. The elevation of gage datum at The Dalles is 45.6 feet 

and at Cascade Locks 42.5 feet above sea level. The locks were formally opened in 1896, and at that time the gage was moved, a datum 

6 feet lower than the former gage being used until December 31, 

1899. The conditions at the locks are such that a permanent rating 

is perfectly feasible. At this point the river breaks over a ledge of 

rock, falling about 20 feet in one-fourth mile. It is practically certain that the channel conditions have remained permanent since the 

readings began in 1879, and the very stable relation which is found 

between the gage records at this point and those at The Dalles indicate that the channel conditions at The Dalles have also been permanent. The drainage area between the two points is about 2,600 

square miles, or about 1 per cent of the total drainage area of the 

river. Hood River, from the Oregon side, and Klickitat and White 

Salmon rivers from the Washington side, are the principal intervening tributaries.

The extreme low-water periods of the intervening streams do not 

coincide with those of the Columbia, occurring in September instead 

of in February. In September the discharge from the rivers intervening is about 1 or 2 per cent of the flow in the Columbia. In February it is probably from 4 to 10 per cent.

In view of the value which long-time records of flow have in a general study of run-off conditions throughout the country, it is believed 

that the discharges determined from the measurements made at The 

Dalles and gage heights at Cascade Locks, and a comparison of the 

gages at The Dalles and the Cascade Locks, will be welcomed by 

engineers of the country. The records are liable to some error at 

extremely low stages, as no measurements have been made below gage 

height 1.4 feet on The Dalles gage, and the relation of the gage readings is uncertain below gage height 0.5 foot, so the low-water discharges prior to 1892 are probably subject to greater error than those 

since that date, since they are made up from the gage readings at 

Cascade Locks.

In the adjustment of a discharge curve among the measurements greater weight was given those made by current meter than 

those by floats. The floats used by the Engineer Corps were long 

rods weighted to float in an upright position, reaching from the surface to as near the bed of the river as practicable. The float and 

meter measurements by the Engineer Corps were made at Cayuse 

Rock over a 1,000-foot range, 7 miles below The Dalles. The float 

measurements of June 20 and July 9, 1908, were made at The Dalles 

gaging station over a 1,000-foot range. The floats used were weighted 

rods, 5 feet in length. The points where they crossed the gage lines 

were determined by a transit. A coefficient of 1.05 was used to 

reduce surface to mean velocities in the vertical. This coefficient is

the mean coefficient from ten vertical velocity curves taken October 

31, 1907. For this measurement a large Price current meter held 

on a piano wire was used. A small cable was thrown across the 

.channel, fastened at the water's edge on each bank, and allowed to 

sag below the surface just sufficient to permit the passage of steamers. The cable was tagged at 10-foot intervals and used to hold a 

small boat from which the meter was operated. In this manner it 

was possible to take velocities at all points in the vertical, although 

depths of nearly 90 feet were encountered. A reeling device was used 

to measure depths whereby the position of the meter below the surface at all times was indicated by a dial. The shape of the vertical 

velocity curves for such depths is found to be somewhat different in 

shallow water, the curve being nearly vertical except near the top 

and bottom, where it curves gently toward the lower velocities. 

This readily accounts for the high coefficient found for surface 

velocities.

The gage height records at both The Dalles and Cascade Locks

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, near 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 

Cosur d'Alene and Cabinet ranges, crossing the "panhandle" of Idaho 

in Bonner County, flowing through Lake Pend Oreille, and entering 

Washington near the town of Newport in Stevens County. From 

Usk to the international boundary line its course is northward, and 

just beyond the boundary it turns and flows directly west to its 

junction with the Columbia. 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 in the 

past a and may still be used locally. The Bitterroot in this decision 

refers to a portion of the main stream so called, and not to the tributary known as the Bitterroot River.

The Land Office maps of Montana, Idaho, and Washington on 

which the Clark Fork drainage area is shown indicates 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.

a 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.)

! 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 but 1,900 feet.

Much of the region drained by Clark Fork and its tributaries is well 

timbered, especially in the mountains, and the drainage area includes 

parts of the Lewis and Clark, Helena, Hell Gate, Missoula, Lolo, 

Bitterroot, Cosur d'Alene, and Cabinet national forests.

As might be expected, 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 nearing 

completion. 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 basis contains many valuable power streams. On 

a few streams power plants have already been installed and more 

are under construction.

The run-off records extend back to 1898. During this period, 1899 

was the wettest year and 1905 was the dryest.

CLARK FORK AT MISSOULA, MONT.

This station was established July 10, 1898, at Higgins Avenue 

Bridge, Missoula, Mont., but was removed May 27, 1899, to the 

bridge of the Bitterroot Valley division of the Northern Pacific Railway, about one-half mile downstream. The gage datum has remained unchanged since the gage was removed. The records supply 

data for power, irrigation, and general statistical purposes. The 

station was discontinued July 1, 1907.

The drainage area at Missoula, including the area drained by the 

Big Blackfoot and the main stream and its smaller tributaries is 

5,960 square miles. Just below Missoula, the Bitterroot enters the 

river and about 100 miles below is the mouth of the Flathead. 

From the source of the stream there are many small water rights, the 

water being used for irrigation. At Bonner, where the Big Blackfoot
84 SUKFACE WATEK SUPPLY, 1907-8.

enters, the Missoula Light and Power Company develop 5,000 

ultimate horsepower and are entitled to the entire flow of the river. 

Another plant is under construction on the Big Blackfoot.

As the climate is mild, this stream usually freezes only partly over 

during the colder months.

Estimates at this station are subject to slight error. The swiftness of the river at high stages may cause the channel to shift. In 

low water it is comparatively sluggish.

Undoubtedly the greatest crest flow occurred in June, 1908, but no 

records are obtainable.

The following measurement was made May 1, 1907: Width, 280 

feet; area, 1,260 square feet; gage height, 5.50 feet; discharge,5,070 

second-feet.

CLARK FORK AT PRIEST RIVER, IDAHO, AND NEWPORT, WASH.

The Priest River station on Clark Fork was established June 26, 

1903, but was discontinued April 30, 1905. It 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 

during the last three winters. The winter records are complete for 

1903-4, 1904-5, and 1905-6.

By comparing simultaneous gage readings at Priest River and 

Newport from April, 1904, to April, 1905, a very satisfactory relation 

has been established. The monthly discharges of Clark Fork at 

Priest River have also been compared with those of Columbia River 

during the winter months when records were obtained at both stations, 

the following percentages being obtained.

NOTE. Discharges for June 26 1903, to April 30, 1905, are based on gage heights at Priest River; since 

May 1, 1905, on the records at Newport, except those for the winter months since December, 1906, which 

have been estimated on percentages of the discharge at The Dalles.
90 SURFACE WATER SUPPLY, 1907-8.

BITTERROOT RIVER ° NEAR GRANTSDALE, MONT.

Bitterroot River rises in the high mountains that form the boundary line between Montana and Idaho, flows northward, and unites 

with Clark Fork a short distance below the city of Missoula. Its 

drainage area comprises about 1,550 square miles. Its tributaries 

are all small. Those from the east drain comparatively low hills 

and add little to the supply of the river, but the west side branches 

are numerous, drain precipitous and heavily wooded areas, and 

their discharge is regulated by many small lakes fed by banks of 

snow, remnants of which continue far into the summer. From 

Hamilton to Missoula, a distance of 48 miles, the fall of the river is 

350 feet, or 7.3 feet to the mile.

The river affords a few possible power sites, but these will probably remain undeveloped for some time, as construction cost would 

be heavy. The water of the stream is extensively used for irrigation, and the valley is probably the best irrigated in the State. Logging is carried on to some extent on this river.

The gaging station was established April 25, 1902, to obtain 

information as to the quantity of water available for irrigation, and 

was discontinued December 31, 1907. It was located on the highway bridge 2 miles southwest of Grantsdale and 5 miles southwest 

of Hamilton. Two large ditches, the New Hedge and the Republican, are taken out of the stream some distance above the station, 

and a large project to irrigate 50,000 acres is now nearing completion. 

The water is taken from Rock Creek, a small tributary rising in Lake 

Como.

The channel is straight above and below the station. The current 

has a medium velocity at moderate stages, but is extremely swift at 

high water. The bed of the stream is composed of bowlders and is 

shifting. The river is partly frozen over during a month or more in 

the winter. The datum of the standard chain gage remained unchanged. Estimates obtained are very good.

FLATHEAD RIVER NEAR POLSOX, MONT.

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.

From August 23 to September 26, 1908, the lake level fell steadily 

from 2,881.1 feet to 2,880.2 feet, as determined by a gage at Poison.

The gaging 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 1908 the mean discharge was 12,100

amount of power can be developed. 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 gage 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.

STILL WATER RIVER NEAR KALISPEL, MONT.

Stillwater River rises in the northern part of Flathead County and 

flows southeastward through several lakes into Flathead River.

The gaging station, which was established September 25, 1906, and 

discontinued May 31, 1907, was located at the Reiter wagon bridge 

2 miles from Kalispel. The flow is controlled by dams above. The 

measuring section is below the mouth of Whitefish River and includes 

the flow of that stream. The intake of the city waterworks is between 

the mouth of Whitefish and the gage. Owing to the extreme sluggishness of the Stillwater above the mouth of the Whitefish, it is 

impossible to make measurements; hence the flow of the Stillwater 

is obtained by subtracting the flow at the Whitefish station from that 

at this station. This gives the amount available for irrigation.

LITTLE BITTERROOT CREEK NEAR DAYTON, MONT.

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.

The gaging station was established April 18, 1908, near Dayton, 

at McDonald's ranch, 12 miles north of the Warm Springs, on 

the Flathead Indian Reservation, and the results 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.

The datum of the gage has not changed since it was established. 

The channel is not likely to shift. This river freezes over in winter.

discharge of neighboring streams.

CROW CREEK NEAR RONAN, MONT.

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.

The gaging 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 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. The gage datum has 

not been changed since the station was established.

98 SURFACE WATER SUPPLY, 1907-8.

This station affords good conditions for obtaining accurate discharge data, as the channel does not change appreciably except 

during flood stages.

MUD CREEK NEAR RONAN, MONT.

Mud Creek, a small tributary of Crow Creek, rises about 6 miles 

southeast of Flathead Lake and flows southwestward.

The gaging station, which was established April 17, 1908, to obtain 

data for irrigation, is located 3 miles northwest of Ronan. The 

United States Reclamation Service will probably use the water on 

the Flathead project. The Pablo ditch, the only one of importance, 

diverts water from the creek a few miles above the station. No 

changes have been made in the gage, as the current is very sluggish 

and it is difficult to obtain accurate results.

o Discharge for April estimated from a measurement made April 17. 

MISSION CREEK NEAR ST. IGNATIUS, MONT.

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. Its only important tributary, Dry Creek, 

enters it just above St. Ignatius.

The gaging station which is located opposite the home of A. A. 

Booke, about 1 mile downstream from St. Ignatius, was established 

September 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.
102 SUEFACE WATER SUPPLY, 1907-8.

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 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.

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.

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 Felman'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, and some of the water 1 or 2 second-feet sinks 

into the ground and is lost before it reaches the gage. At low and 

medium stages none of the water reaches Mission Creek, and during 

the winter and early spring it 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.

POST 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 it is possible to equalize the flow of the stream 

throughout the year by storage in the lake.

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.

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. The 

gage datum has remained unchanged.

JOCKO EIVER NEAR JOCKO, MONT.

Jocko River rises in the eastern part of the Flathead Indian 

Reservation and flows in a general northwesterly direction into 

Flathead River near Dixon.

The station, which was established August 20, 1908, to obtain 

data for irrigation, is located near the highway bridge on the road 

between Jocko and Ravalli about 1{ miles northwest of the Jocko 

Agency. The Reclamation Service is now irrigating the Jocko 

Valley. Big Knife and Blodgett creeks enter the 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 in the upper Jocko Valley.

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.

Although the waters of this stream are being used for irrigation, 

its power possibilities could be developed. The river 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 gaging station is located about 400 feet downstream from a 

point opposite the railroad station at Ravalli. It was established 

October 18, 1906, to obtain data for use in connection with irrigation 

and power development.

Several small ditches divert water above the gage for irrigation. 

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.

a Gage heights for May 30 to July 21 are uncertain, as the gage settled about June 1 and was not corrected until July 21. No ice at this station.

& The gage was washed out June 2 by high water and was replaced June 25 at the same datum. The 

highest stage of the flood was determined by high-water marks to be 7.63 feet, and probably occurred 

about June 10.

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 the 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.

There are no ditches diverted from this stream. The water may 

possibly be utilized by the Reclamation Service. As the creek has 

a high altitude, it freezes over in cold weather. The 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 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. 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.

FINLEY CREEK NEAR JOCKO, MONT.

Finley Creek, a tributary of Jocko River, is formed by its East 

and West forks, which rise in the Mission Range and unite about 

one-eighth mile above the gaging stations.

The station, which was established August 19, 1908, is located at 

the ford 2^ miles south of Jocko and 3^ miles east of Arlee, and is 

300 feet south of the Northern Pacific Railway. No ditches of 

importance are diverted from this creek, but possibilities are good 

and the Reclamation Service will utilize this water on the Jocko 

project.

The stream freezes over in the winter. The gage datum has 

remained unchanged. The accuracy of the measurements is good.

EAST FINLEY 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 gage is permanent and the datum 

has remained unchanged.

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 East Finley gage. 

The 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 vicinity of Jocko Agency. The Reclamation Service contemplates enlarging it and increasing its capacity. During the irrigating season the ditch carries about 6 second-feet. Accuracy of 

measurements is fair.

VALLEY CREEK NEAR RAVALLI, MONT.

This station was established August 20, 1908, at the crossing of the 

highway between Jocko and Ravalli. It is 3 miles east of Ravalli, 

8 miles west of Arlee, and near the mouth of the stream, which, is a 

tributary of Jocko River. It was established in order to obtain 

comparative results. The gage is read only at times when the engineer 

visits it.

Data obtained on this creek are for use in connection with irrigation 

projects. An ordinary staff gage is placed on the left bank above 

the bridge. Measurements are made by wading.

SPOKANE RIVER DRAINAGE BASIN.

DESCRIPTION.

Spokane River rises in Lake Cceur d'Alene in western Idaho, at 

an elevation of 2,124 feet above sea level, flows westward and northwestward and empties into Columbia River in the north-central part 

of Lincoln County, Wash. The river is used for both water power 

and irrigation. Large power plants are located at the falls at Spokane 

and at Post Falls, Idaho, and a large plant has recently been completed 9 miles below Spokane. The total water power developed from 

this stream aggregates 45,000 horsepower. Irrigation is practiced in 

the valley of Spokane River and its tributaries.

The mean annual rainfall at Spokane is 17 inches, an amount which 

is fairly representative of the drainage area.

The following gaging stations have been maintained in this river 

basin:

Spokane River at Spokane (1896 to 1908).

Little Spokane River near Spokane (1903 to 1905).

Hangman Creek at and near Tekoa (1904 and 1905).

North Fork of Hangman Creek near Spokane (1904 and 1905).

SPOKANE RIVER AT SPOKANE, WASH.

This station was originally established October 17, 1906, and the 

records are practically continuous since that date, although the location of the station has been changed from time to time in order to 

secure better gaging conditions. The station is above the mouth of 

Hangman Creek, and there are no important tributaries above the 

station. The present location is at Martha street crossing, onefourth mile above the Mission Street Bridge, a cable station being
118 SURFACE WATER SUPPLY, 1907-8.

established at this point April 11, 1904. The gage was located on the 

piers of the Mission Street Bridge and was read until March 1, 1907. 

Since that date the gage at the cable has been used for daily observations. The gages at Mission street and Martha street were read 

simultaneously during March, 1907, to determine the relation between them, and the records for January and February have been 

reduced to Martha street gage. The datum of the Martha street gage 

is 1,851.926 feet above sea level.

The data at this station are valuable in connection with both water 

power and irrigation development. The water power developed 

within a short distance of the gaging station probably aggregates 

45,000 horsepower.

The conditions at the present gaging site are favorable for good 

results. The channel is not always stable, and slight changes occur 

which make it necessary to modify the rating curve from time to 

time, particularly for the lower stages.

Excessive and damaging floods are hardly possible on this stream, 

as the flow is controlled by natural storage in Lake Cceur d'Alene.

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
OKAlSTOGAlSr RIVER DRAINAGE BASIN. 121

per annum. The principal tributaries in the United States are 

Similkameen and Conconully rivers and Antwine, Bonaparte, 

Salmon, and Johnson creeks.

The main stream is navigable from Brewster to Riverside, except 

during low-water periods, while the tributaries are used largely for 

irrigation.

The following gaging stations have been maintained in this river 

basin:

Sinlaheekin Creek near Loomis (1903 to 1905). 

Johnson Creek near Riverside (1903 to 1907). 

Salmon Creek near Malott (1903 to 1908).

JOHNSON CREEK NEAR RIVERSIDE, WASH.

Johnson Creek is a very small stream, but as the water rights are 

not settled a record of its flow was necessary in the development of 

the Okanogan project. This station, which was established May 30, 

1903, and abandoned December 31, 1907, was located near the mouth 

of the stream. The equipment consists of a rectangular weir, 8 feet 

long. On March 7, 1907, the crest of the weir was level, but the zero 

of the gage was one-tenth higher than the crest of the weir during 

1905 to 1907. The post to which it was fastened probably had been 

raised by ice. The datum of the gage was 1,228.63 feet above sea 

level.

Daily discharge, in second-feet, of Johnson Creek near Riverside, Wash., for 1907.

SALMON CREEK NEAR MALOTT, WASH.

This station, which was established May 27, 1903, is located on 

the stage road between Malott and Conconcully, 14 miles from 

Malott and 11 miles from Conconcully, and is 6 miles above 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. 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 conditions at the station are favorable for good results if a 

sufficient number of measurements are made each year. The bed of 

the creek, however, is not stable, and a number of rating curves have 

been used. The measurements have been made by the engineers of 

the Okanogan project, and the results furnished to the Geological 

Survey, but they are too incomplete to form an accurate basis for 

estimates of flow.

METHOW RIVER DRAINAGE BASIN.

METHOW RIVER AT PATEROS, WASH.

Methow River rises on the eastern slope of the Cascade Mountains 

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 that of Lake Chelan, 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.

The gaging station, which was established November 9, 1903, is 

located about 1 mile above the mouth of the river and the town of 

Pateros. 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 the records are as reliable as could be expected with the few 

measurements it has been possible to obtain during the past two 

years.

It is notable that the conditions which caused damaging floods on 

nearly all other streams draining the Cascade Range on November 

14 to 16, 1906, did not have any effect on this river.

128 SURFACE WATER SUPPLY, 1907-8.

MISCELLANEOUS MEASUREMENT.

A measurement of the Pateros ditch at the highway crossing, near 

K. K. Parker's ranch, near Pateros, April 15, 1907, gave a discharge 

of 3.8 second-feet. Water surface was 1.92 feet below top of bridge

floor.

CHELAN RIVER DRAINAGE BASIN.

CHELAN RIVER AT CHELAN, WASH.

Chelan River, which enters Columbia River at Chelan Falls, forms 

the outlet of Chelan Lake, a narrow body of water, 48 miles long, 

lying at an elevation of 1,080 feet above sea level. The area contiguous to the lake is exceedingly rough and mountainous and lightly 

forested.

The mean annual rainfall at Chelan is 13 inches.

This station wT as established November 6, 1903. It is located just 

below the outlet of Chelan Lake, 4 miles northwest of Chelan Falls, 

in the town of Chelan.

The data obtained at this station are valuable principally for use 

in water-power development, as the river has a fall of 380 feet in the 

4 miles between the outlet of the lake and the junction of the river 

with the Columbia.

Sufficient measurements have not been made to give good results 

at this station, as the channel appears to be somewhat shifting. The 

flow of the river is partially controlled by a dam at the foot of the 

lake.

WENATCHEE RIVER DRAINAGE BASIN. 

WENATCHEE RIVER AT CASHMERE, WASH.

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 emptying into Columbia River at the town of 

Wenatchee,
WENATCHEE EIVEK DRAINAGE BASIN. . 131

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 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.

Irrigation has been extensively practiced in the lower portion of 

the area, but is confined to the valley lands contiguous to the streams. 

The Wenatchee Valley has become justly famous for its apples and 

other fruits, and lands for orchards are valued at $1,000 per acre and 

upward.

The gaging station, which was established July 26, 1904, is located 

at the upper highway bridge in Cashmere, one-half mile below the 

mouth of Mission Creek, and 8 miles above the mouth of the river.

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

development of irrigation and water power. The Great Northern 

Railway has recently built a hydro-electric plant to run the trains 

through the Cascade tunnel by electric power.

The conditions at the station are not at all favorable for good 

results, and it is somewhat doubtful if the datum of the gage has been 

maintained absolutely since the station was established. During 

the summer of 1907 the highway bridge was rebuilt and the gage 

removed. A temporary gage was installed by the observer November 17, 1907. The observer reports that this temporary gage was 1 

foot above the gage datum as determined by water levels. This 

temporary gage was destroyed March 16, 1908, and on April 7, 1908, 

the observer installed a temporary gage which was used until September 28, 1908, when a permanent gage was installed and the corrections for the temporary gage determined. The gage heights have 

been corrected to correspond with the original gage datum.

The lowest discharge on this stream occurs during the winter 

months, when the headwaters are icebound.

Owing to uncertainty regarding the accuracy of the gage heights, 

estimates of monthly discharge for 1907-8 are withheld until more 

information can be obtained.

The following measurement was made September 28, 1908: Width, 

109 feet; area, 344 square feet; gage height, 0.90 foot; discharge, 

665 second-feet.

o The river was partly frozen over January 1 to February 8; the ice reached a maximum thickness of 12 

inches along the shore. The middle of the channel remained open and slush ice was running most of the 

time.

During the summer the highway bridge was built and the gage removed. A temporary gage was installed 

by the observer November 17. The observer reports that the temporary gage was 1 foot above gage 

datum as determined by water levels. Gage readings have been corrected.

6 Gage readings January 1 to March 16 were taken from temporary gage installed November 17, 1907.

The gage was washed out March 16, and another temporary gage installed April 7, which was used until 

September 28, when a permanent gage was installed. All gage heights are liable to considerable error.

YAKIMA RIVER DRAINAGE- BASIN. 133 

MISCELLANEOUS MEASUREMENT.

A measurement of Mission Creek at the bridge one-fourth mile 

above the mouth near Cashmere, April 13, 1907, gave a discharge of 

194 second-feet. Water surface was 3.05 feet below an 8d. nail in 

east face of cottonwood tree on left bank, 25 feet below the bridge.

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 River. Its drainage area comprising 5,270 

square miles, extends southward from the Wenatchee Mountains 

within 20 miles of Columbia River and includes a stretch of nearly 100 

miles of the eastern slopes of the Cascade Range. It has many tributaries, the most important coming from the west, as is shown by the 

following table:

Principal tributaries of Yakima River.

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

Kachess River (Kachess Lake). 

Clealum (Clealum Lake). 

Teanaway Creek. 

Swauk Creek. 

Kittitas Creek. 

Cherry Creek.

Big Creek.

Taneum Creek.

Man-as-tash Creek.

Wenas Creek.

Naches River (draining about 50 miles of 

Cascade Range).

Tieton River.

Cowiche 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 very 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 is 2,230, Clealum Lake 2,130, Ellensburg 1,545, NorthYakima 

1,090, and Kiona 515 feet.

The agricultural lands of this basin lie in four distinct valleys. The 

upper one, which begins just below the mouth of Swauk Creek, is 

known as the Kittitas Valley. It is somewhat oval in shape, about 

30 miles long by 16 miles wide. Ellensburg is its chief city. Below 

the 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 the 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
134 SURFACE WATER SUPPLY, 1907-8.

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 individual 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 successsful operation for a number of years. The products produced 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 the basin. Irrigated orchards in the vicinity of North Yakima 

have attained a value of $1,000 to $3,000 per acre. It is recognized 

that only through the development of storage can the fullest use of 

the waters be made. (See PI. Ill, B, p. 36.)

The United States Reclamation Service has undertaken the general 

development of this valley. The principal storage reservoirs are 

found in Lakes Keechelus, Kachess, Clealum, and Bumping, and at 

McAllister Meadows on Tieton River. The development of the 

projects will be made in several units. The first was accomplished by 

the purchase of the Sunnyside Canal, which diverts water from the 

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 River 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. The third unit, on which work is progressing at 

present, is the Wapato project, which contemplates the enlargement 

and extension of two canals built by the United States Indian Service 

and the development of small storage reservoirs on the headwaters of 

Toppenish Creek. The lands to be irrigated are largely included in 

the Yakima Indian Reservation.

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 

Company. 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.
YAKIMA RIVER DRAINAGE BASIN. 135

The following gaging stations have been maintained in this basin:

Yakima River near Martin (1903 to 1908).

Tieton River at headworks, near Natches (1906 to 1908).

Tieton River near Naches (1902 to 1908).

North Fork of Atanum Creek, near Tampico (1907 to 1908).

Atanum Creek at The Narrows, near Tampico (1908).

Atanum Creek near Yakima (1904 to 1908).

South Fork of Atanum Creek, near Tampico (1907 to 1908).

Toppenish Creek near Toppenish (1908).

Satus Creek near Alfalfa (1908).

In addition to the data collected at the river stations, records of the 

principal canals diverting water from the Yakima River and tributaries were kept during the irrigating season of 1904 and 1905. The 

following regular canal stations have been maintained:

New Reservation canal near Yakima (1904 to 1908). 

Old Reservation canal near Wapato (1904 to 1908). 

Sunnyside canal near Yakima (1904 to 1908). 

Kiona canal near Kiona (1904, 1905, and 1908).

Lake gages have also been observed, as follows:

Lake Keechelus near Martin (1906 to 1908). 

Lake Kachess near Easton (1905 to 1908). 

Lake Clealum near Roslyn (1906 to 1908).

Records of evaporation have been obtained in Lake Kachess (1907 

and 1908), and also in Sunnyside canal at Zillah (1907 and 1908).

LAKE KEECHELUS NEAR MARTIN, WASH.

A gage was established in Keechelus Lake January 12, 1906, It is 

located just above the outlet of the lake, 4 miles northeast of Martin, 

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 later datum, which is 

2,457.00 feet above sea level.

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 at Martin, to compute the inflow into the lake.

YAKIMA RIVER NEAR MARTIN, WASH.

This station was established October 18, 1903. It is located at the 

outlet of Lake Keechelus, 4 miles northwest of Martin station on the 

Northern Pacific Railway.

The data here obtained are used by the United States Reclamation 

Service in their general studies for the reclamation of lands in the 

Yakima River valley. Lake Keechelus is at present used as a 

storage reservoir. A temporary timber dam has been constructed, 

which will be replaced later by a permanent dam high enough to 

fully develop the storage capacity of this area.

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 here. The datum of the gage, which 

is 2,448.76 feet above sea level, has not been changed since it was 

installed, although a number of rating curves have been necessary. 

The flood of November 14, 1906, changed the channel somewhat, 

and later an attempt was made to improve channel conditions by 

shattering some of the larger bowlders above and below the station 

with dynamite.

While dam was under construction, January 19 to April 16, water was shut off during the day and allowed 

to run nights, Sundays, and some other periods when it was impossible to work.

Water was shut off from September 17 to 10 a. m. October 9.

& Flow shut off at lake on days when gage height is not given.

a This table is not applicable for ice or obstructed-channel conditions. It is based on five discharge 

measurements made during 1907 and is well defined between gage heights 6.4 feet and 8.7 feet. The 1906 

rating table is used from January 1 to 7.

6 This table is not applicable for ice or obstructed-channel conditions. It is based on three discharge 

measurements made during 1908 and the higher 1907 measurements, and is well denned between gage

NOTE. The amount of water stored has been computed from the gage height and storage table for Late 

Keechelus. The "natural" run-off in acre-feet and mean discharge represent the flow into the lake, less 

evaporation, or the run-off and discharge that would have occurred had the lake been held at a constant 

level.

YAKIMA RIVER AT CLEALUM, WASH.

This station, which was established August 25, 1906, for the purpose 

of determining the most economic method of operating the storage 

reservoirs contemplated and under construction on the headwaters 

of Yakima River by the United States Reclamation Service, is 

located just above the town of Clealum, 6 miles above the mouth of 

Teanaway River, and 3 miles below the mouth of Clealum River. 

The flow obtained here is taken in conjunction with that at Umtanum 

and Union Gap in the distribution of stored waters.

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. Ice conditions, 

which obtain for a short period during the winter months, affect to a 

small degree the accuracy of the data. At such times, and where 

other means fail, the data are usually supplied by interpolation.

NOTE. The amount of stored water at this station is the sum for Lakes Keechelus, Kachess, and Clealum. 

YAKIMA RIVER AT UMTANUM, WASH.

This station, which was established August 25, 1906, is located at 

Umtanum Siding, in the canyon of Yakima River between the Selah 

and Kittitas valleys, 1 mile above the mouth of Umtanum Creek. 

The station has great value in the general scheme of reclamation 

undertaken by the United States Reclamation Service, for 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 conditions at this station are favorable for good results and 

the data obtained are reliable. A riffle control is located about 100 

yards below the gaging section, and although high floods will change 

the cross section at the point of measurement these changes are 

counterbalanced by corresponding changes in velocity; thus the gage
144 SURFACE WATER SUPPLY, 1907-8.

height is always a stable index of the flow. The estimates during 

the winter months are rendered somewhat uncertain by ice conditions, but as these conditions do not prevail for very long periods and 

do not occur at critical stages the errors due to this cause are not great.

i Discharges for periods when there were ice conditions, or when gage was not read, have been estimated 

by multiplying the discharge at Clealum by the following coefficients: January 1 to February 9, 1.50; 

May 21 to 31, 1.25; June, 1.05; July, 1.00; August 1 to 9, 0.90; Comparisons of the discharge at the two 

stations for periods covered by the records indicate that these are the most probable ratios.

YAKIMA RIVER NEAR YAKIMA, WASH.

This station, which is located at Union Gap, a narrow gap in the 

lower Yakima-Moxee valleys, was established August 14, 1893, but 

discharge can be computed only from August 19, 1895, as the records 

are fragmentary prior to that date. The station is of great importance 

in determining the discharge, as it is unaffected by the diversions for the 

large irrigated areas above and below. It is just below the mouth of 

Atanum Creek and above the head gate of the New Reservation canal, 

the distance between these points being less than one-half mile. The 

discharge at this point is approximately equal to the sum of the discharge of Yakima River at Umtanum and 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, 

the Old and the 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
YAKIMA RIVER DRAINAGE BASIN. 147

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 is nearly complete for 1908, but no rating table can be applied to them, as no 

measurements were made during 1908. The discharge has been 

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. The discharge can 

seldom be corrected for these conditions and is therefore liable to

some error.

NOTE. Discharges for May to December, 1908, were obtained by adding the flow of the Sunnyside, Old 

and New Reservation canals to the flow over the Sunnyside dam.
150 SUKFACE WATER SUPPLY, 1907-8.

YAKIMA RIVER NEAR WAPATO, WASH.

This station, which was established April 25, 1908, is located 

at the headgate 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, (See PI. VI.) The gage readings show the head 

of water on the crest of this dam and are obtained by means of a 

hook gage. The discharge measurements are made from a cable 

which spans the river 500 feet below the dam. A sluiceway in the 

dam is closed by means of flashboards during the irrigating season. 

On this account two rating curves have been developed; one for 

the sluiceway open and the other for the sluiceway closed. There 

is also a fish ladder near the sluiceway through which a small quantity of water flows all the time.

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. The Old Reservation canal diverts water from the right 

bank of Yakima River, one-half mile above this station; the New 

Reservation canal takes it from the same bank 2 miles above. The 

Union Gap canal (Lombard Horseley ditch) diverts water from 

the Moxee Valley, which is carried to Union Gap to irrigate lands 

to the east and south of this station. During the irrigating season 

the natural flow at this point is augmented by the release of stored 

waters in Lakes Keechelus, Kachess, and Clealum, where temporary 

dams have been constructed and operated by the Reclamation 

Service.

The records obtained here are as reliable as can be obtained by 

calibration of a permanent overflow dam by means of a current 

meter, and, although the river is subject to freezing during the 

winter months, the ice conditions do not interfere with records at 

this point.

YAKIMA RIVER AT KIONA, WASH.

This station, which was established August 20, 1895, is located 

in the town of Kiona, 23 miles above the mouth of the river. 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 above and below 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. 

There is also a wasteway from the extremity of the Sunnyside canal 

where the amount wasted is measured, but as it flows in a natural 

channel to the river from the point of measurement a part of the 

water is again diverted in small ditches for irrigation. During the 

irrigating season little or no surface water reaches the river from this 

wasteway, although a large part of it, doubtless, finds its way through 

the gravel bed of the arroyo.

The flow at the gaging station is controlled by a riffle about 1,000 

feet below the bridge, and this has made the development of a permanent rating curve possible. The gages have been altered during the 

life of the station, but 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. The data of 

1907-8 are not greatly complicated by ice conditions.

a On January 1 the river froze about one-fourth way across from each bank, the ice varying from 2 to 8 

inches in thickness. This ice went out February 5, forming an ice gorge and causing a sudden rise in gage 

height. There was probably ice obstruction during the latter part of February. There was a heavy flow 

of slush ice from January 1 to February 5, but the main channel was open at all times.

*> There was slush ice January 31 and February 1; shore ice, February 2 and 3,10 feet from either bank 2 

inches thick. The main channel was clear throughout the year.

YAKIMA RIVER NEAR RICHLAND, WASH.

This station was established July 28, 1906, and has been maintained during irrigating seasons only.

The data are of particular value in showing the amount of water 

that is contributed by the Yakima to Columbia River during the 

irrigating season, after the irrigation requirements have been satisfied. 

It is located below all important diversions. In 1907 it was located 

at Richland Ferry, 8 miles above Kennewick, 2^ miles above the 

mouth of the river. As conditions were poor it was necessary to use 

temporary gages which were washed out at the first rise in the fall, 

and the station was discontinued as soon as the river rose to a height 

where measurements could not be made by wading. During 1908 it 

was located at the bridge 3 miles below its former position, but an 

insufficient number of measurements were made to form the basis of 

an estimate of flow. The gage heights, however, will be applicable to 

a rating curve developed later, as the channel conditions are stable.

The following measurement was made August 13, 1907, 1,000 feet 

above the bridge:

Width, 140 feet; area, 142 square feet; gage height, 2.50 feet; 

discharge, 199 second-feet.

Daily gage height, infect, of Yaldma River near Richland, Wash., for 1907 and 1908.

KACHESS LAKE NEAR EASTON, WASH.

Kachess Lake is divided into two parts, known as Kachess and 

Little Kachess, which are connected by a short channel called The 

Narrows. The elevation of the water surface is 2,230 feet above sea 

level, and the superficial area at the medium stage is 3,600 acres. 

A gage was established in Lake Kachess September 20, 1905. It is 

located about 300 feet above the dam at the outlet. The gage 

datum in this lake is at an elevation of 2,227.02 feet above sea level 

and has not been changed since the gage was installed.

Daily gage height, in feet, of Kachess Lake near Easton, Wash., for 1907 and 1908.

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 Kachess River, to compute the inflow into the lake.
158 SURFACE WATER SUPPLY, 1907-8.

KACHESS RIVER NEAR EASTON, WASH.

This station, which was established October 14, 1903, is located 

one-half mile below the outlet of Lake Kachess and 2 miles northwest 

of Easton. The river receives no important tributaries.

This station is of great value, as the records determine the amount 

of water available for storage in Lake Kachess, which forms one of 

the principal reservoirs under consideration by the United States 

Reclamation Service, and will probably be the first one constructed 

on the headwaters of Yakima River.

The channel is open throughout the entire 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 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 has been used.

The flow is under artificial control, the lake being used for storage 

by the Cascade Canal Company prior to its acquisition by the United 

States Reclamation Service.

NOETH FOEK OF CLEALUM EIVEB, AT GALENA, WASH.

This station, which was established June 16, 1907, is located at 

Galena post-office, just below the mouth of Camp Creek, 1 mile above 

the mouth of Boulder Creek and 5 miles above the junction of North 

and Middle forks of Clealum Kiver. It is not possible with the 

present data to form an estimate of the flow, but the gage heights are 

complete for the low-water season of 1907, and it will be possible later 

to develop a discharge curve to which these heights can be applied.
YAKIMA RIVER DRAINAGE BASIN. 161

The following measurement was made June 16, 1907: 

Width, 35 feet; area, 180 square feet; gage height, 5.24 feet; discharge, 250 second-feet.

Daily gage height, in feet, of North Fork of Clealum River at Galena, Wash., for 1907.

CT>EALUM LAKE NEAR ROSLYN, WASH.

Observations of the height of Clealum Lake were begun January 

25, 1906. Four gages have been used at this point:

Gage No. 1 was in operation January 25 to March 31, 1906. On 

the later date this gage was washed away by \vaves during a storm 

on the lake. As the gage was not referred to any bench mark and the 

datum is lost for that period, the heights reported are not comparable 

with subsequent records.

Gage No. 2 was installed May 4, 1906. It is located above the outlet of the lake and indicates the true height of the w^ater surface of 

the lake.

Gage No. 3, which was installed June 17, 1907, is attached to the 

abutment of the dam located about 200 feet below the outlet of the 

lake. The zero of this gage coincides w-ith the top of the sill on the 

bottom of the outlet tunnels in the dam. It was expected that when 

water was stored the natural fall between the outlet and the dam 

would be obliterated and the gage readings on Nos. 2 and 3 w^ould 

then be comparable.

Gage No. 4 is a stilling box gage installed November 9, 1907, at the 

same datum and locality as No. 3. The datum of the gage No. 2 is 

0.45 foot belowr the datum of gage No. 3, and it was the intention to 

correct all previous heights observed on gage No. 2 to the datum of 

gage No. 3. Since gage No. 3 was installed the records on No. 2 were 

inadvertently suspended, except from July 7 to November 9, 1907, 

11947 10- 11
162 SUEFACE WATER SUPPLY, 1907-8.

when simultaneous records were kept. On March 4, 1908, the flashboards were placed in the dam and storage of water began. By 

March 15, 1908, the water had reached sufficient height to obliterate 

the natural fall of the water surface between the outlet of the lake and 

the dam, and although observations were taken on gage No. 3 they 

have been made comparable with the datum of No. 2 by correcting 

them + 0.45 foot. This will hold until such time as the water is drawn 

down to about 5 feet on gage No. 3, when the fall between the outlet 

and the dam will again be visible. The observed heights from May 4,

1906. to June 17, 1907, and from July 7 to November 9, 1907, and the 

corrected heights from March 15 to December 31, 1908, are given in 

the first table. From June 17 to July 7, 1907, and from November 9,

1907. to March 14, 1908, the observations from gage No. 3 (or No. 4) 

are given in the second table. They are not comparable, except in 

an approximate way, with those in the first table. Simultaneous 

readings taken between July 7 and November 9, 1907, do not reveal 

a consistent relation between the two gages, as the fall is variable, 

depending upon the number of flashboards in place and upon the 

amount of water allowed to pass the dam.

The normal water surface of Clealum Lake is at an elevation of 2,130 

feet, and the area of the lake is 2,200 acres at that height. The zero 

of gage No. 2 is 2,122.30 feet above sea level.

NOTE. This table is for gage No. 2, on the lake.

CLEALUM RIVER NEAR ROSLYN, WASH.

This station, which was established October 10, 1903, is located 

at the outlet of Clealum Lake, which is to be utilized for storage by 

the United States Reclamation Service.

The data obtained are of great value in connection with the development of irrigation in the Yakima Valley, and particularly in 

determining the economic storage capacity of this area.
YAKIMA BIVER DBAINAGE BASIN. 165

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 Company, and the flow during the summer 

months was therefore partially under control, although the dam was 

of temporary construction and was replaced each season.

o Discharges have been recomputed for gage heights of less than 2.1 feet, using the 1907-8 table. These 

values supersede those given in \V. S. P. 214, p. 56.

& Discharges have been interpolated from June 10 to July 17, inclusive, and from July 19 to August 4, for 

days on which gage was not read.

c Mean discharge for February 1 to 9 has been estimated at 400 second-feet, by comparison with other 

stations and considering the rise of Clealum Lake. The flow during August and September, 1907, and during July and August, 1908, is too high, as the dam at the outlet of Lake Clealum was under construction 

and repair. The water was usually shut oft during a part of each twenty-four hours on working days.

NACHES RIVER NEAR NILE, WASH.

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,
168 SURFACE WATER SUPPLY, 1907-8.

among which may be mentioned Bumping River, Rattlesnake Creek, 

Tieton River, and Cowiche Creek. Of these the Tieton is the most 

important. The headwater streams drain a very mountainous 

country (PI. V, A and B).

This station, which was established June 25, 1904, is located If 

miles above the mouth of Tieton River, and one-half mile above the 

headgate of the Selah Valley canal, the highest diversion from 

Naches River.

The records of flow obtained at this station are of considerable 

value, in connection with the irrigation projects in the valley. The 

waters of the river are entirely used for irrigation during the summer 

months. The United States Reclamation Service proposes to divert 

the entire flow of Tieton River and replace this amount by constructing a storage reservoir at Bumping Lake on the headwaters of the 

Naches, and the station data are necessary to facilitate the intelligent 

and economical distribution of storage waters.

The gage was destro}^ed by the flood of November 15, 1906, but it 

was replaced at the same datum on January 28, 1907. The gage 

datum has not been changed since the station was installed, although 

changes in the stream bed have made it necessary to revise the rating 

curve at various times. During the winter months the river is frequently icebound, although no ice gorges form so as to affect the gage 

heights at the station. Anchor ice frequently forms in the bed of the 

stream and the water freezes over in the quieter portions of the gaging 

section. The records of winter flow, therefore, are not as reliable as 

could be desired, and where they have affected the results due allowances have been made.

NACHES RIVER NEAR NORTH YAKIMA, WASH.

This station was first established August 14, 1893, 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 at Union 

Canal, one-half mile above the mouth of the river. The North Yakima 

power canal, however, diverts 80 to 200 second-feet past the gaging 

station continuously. 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 and car between the 

two bridges. Gages have been maintained below the railroad 

bridge and on the highway bridge, and on the cribwork which extends 

as a protection for the approach to the railroad bridge on the right 

bank.

The conditions have never permitted of a permanent rating curve. 

The stream is subject to heavy floods, and during such times the bed, 

which is composed of gravel and cobblestones, changes so materially 

that a new rating is required after each high water. The present 

location of the station was chosen June 18, 1908, when a gage was 

installed on the right bank, 800 feet above the railroad bridge. The 

datum of the gage bears no determined relation to the earlier gage 

datums. The river at this point is spanned by a long cable reaching
172 SURFACE WATER SUPPLY, 1907-8.

from the high bluff on the left bank to an artificial dike on the right 

bank. At all ordinary and medium stages a permanent rating 

curve can be developed, but it is likely that an excessive flood will 

make it necessary to develop an entirely new rating curve.

During the winter months ice conditions interfere with the determination of flow to a considerable extent. The ice which forms in 

the river frequently jams at the railroad bridge, and during such periods it is necessary to interpolate the records of flow.

NOTE. On March 30, 1907, a new chain gage was installed at the new toll bridge to replace the one destroyed by the flood of November, 1906. Datum the same as previous chain gage. This chain gage replaced 

a temporary staff gage installed November 22, 1906.

On December 10,1907, the bridge was removed and with it the chain gage. A vertical staff gage was installed on the pile foundation of an old concrete pier on right bank about 50 feet upstream from end of old 

bridge. The gage was set at same datum as chain gage.

On June 18, 1908, a new vertical staff gage was installed about 800 feet above railroad bridge, and a few 

days later a new chain gage was installed reading the same as vertical gage.

a This table is not applicable for ice or obstructed-channel conditions. It is based on 2 discharge 

measurements made during November, 1906, and the 1907 table, and is fairly well denned. It is used 

because the gage heights for this period refer to a datum 0.30 foot below the one used before and after.

b This table is not applicable for ice or obstructed-channel conditions. It is based on 12 discharge 

measurements made during 1907 and is well denned. This table applies to gage heights from the chain 

gage established March 30, and to those from the temporary gage, which have been corrected to the same 

datum.

cThis able is not applicable for ice or obstructed-channel conditions. It is based on 1 discharge 

measurement made during 1908 and the 1907 low-water measurements and is fairly well defined. Below 

gage height 6.7 feet it is the same as the previous table. This table is for the staff gage, which was set 

to read the same as the chain gage at low stages, but as the fall between the gages became greater at high 

water a different table is necessary.

d This table is not applicable for ice or obstructed-channel conditions. It is based on 6 discharge 

measurements made during 1908 and is well defined above gage height 2.9 feet. It gives the discharge 

for gage heights on chain gage 800 feet upstream from railway bridge.

YAKIMA RIVER DRAINAGE BASIN. 177

TTETON RIVER AT HEADWORKS OF TIETON CANAL NEAR NACHES,

WASH.

This station, which was established March 29, 1906, was moved on 

June 27, 1907, 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. 

There are no tributaries in the immediate vicinity of the station. 

Two gages have been used the one at the cable, where measurements were made; the other at Weisberger's power plant, 1J miles 

downstream. The measurements are referred to both gages, and a 

rating curve has been developed for each.

The records obtained at this station furnish data of great value 

in connection with the general reclamation of the Yakima Valley. 

The entire flow of Tieton River at low water 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 Naches River.

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.

it was located just below the mouth of Oak Creek. On the latter 

date it was removed to a point 200 feet above the mouth of Oak 

Creek, thus excluding 19 square miles of drainage area. On March 23, 

1907, the station was again moved to the highway bridge at Camp
YAKIMA EIVER DRAINAGE BASIN. 181

No. 1 of the United States Keclamation Service, where construction 

of the Tieton Canal tunnels was under way. At this point a power 

plant was built for the generation of electric power to be used in the 

excavation of the tunnels. As the bridge from which the measurements were made and the gage are both located between the intake of 

the canal and the power house, the flow of the canal should be added to 

that obtained in the river in order to represent the natural flow of the 

stream. It was impracticable to rate the power canal, and on this 

account no estimates of the flow at this point have been made since 

the power canal was put in operation, July 10, 1907.

184 SURFACE WATER SUPPLY, 1907-8.

NORTH FORK OF ATANUM CREEK NEAR TAMPICO, WASH.

Atanum Creek, which is formed by the union of North and South 

Forks, near Tampico, in Yakima County, 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.

A gaging station was established August 26, 1907, on the North 

Fork at Goodman's ranch, 3^ miles above the junction with South 

Fork, and 100 feet below the mouth of Nasty Creek. It is above all 

diversions from the stream.

The data obtained here have considerable value as the waters of 

this stream are extensively used for irrigation throughout the Atanum 

Valley by both Indian and white settlers.

The conditions at the station are not favorable for very accurate 

results. The station was installed primarily to determine the lowwater flow. The current is swift and there are no facilities for making 

measurements except by wading. An estimate of the flow at higher 

stages has been made by extending the discharge curve. The records 

at the station are not complete, as it was impossible to obtain continuous observation of gage height.

ATANUM CREEK AT 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," 3^ miles east of 

Tampico and 3 miles below the junction of North and South forks.

The flow here presumably includes all return waters from irrigation in the upper part of the drainage basin; but this presumption 

is very doubtful as the situation is greatly complicated by an innumerable number of small ditches both above and below the station, 

and the records should not be considered to represent the natural 

run-off from this drainage area.

ATANUM CREEK NEAR YAKIMA, WASH.

This station was established May 11, 1904, and was discontinued 

December 30 of the same year because of poor gaging conditions. 

Observations were again resumed August 27, 1907, at the same point. 

The present 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 creek forms the 

northern boundary of the Yakima Indian reservation, and the 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 portions of the stream there is a considerable 

quantity of return water from irrigation which is measured at this 

station.

The station does not furnish favorable conditions, and the gage 

readings are not very good. The water at the gage is considerably 

disturbed by riffles. No ice forms to interfere with the determination 

of discharges.

SOUTH FORK OF ATANUM CREEK NEAR TAMPICO, WASH.

This station, which was established August 27, 1907, is located at 

Shanafelt's ranch, 2 miles above Tampico and 2^ miles above the 

junction with the North Fork. It is above all important diversions, 

but two or three small ditches divert water for individual tracts of 

land above the station.

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

the use of the waters of the stream for irrigation by both Indian and 

white settlers. This portion of the river forms the northern boundary of the Yakima Indian Reservation.

It was impossible to find a favorable section for the accurate 

determination of the discharge. The banks of the stream are very 

thickly covered with willows and the channel is not permanent. 

The measurements are made by wading at any suitable point that 

can be found, or from a private bridge one-fourth mile below 

the gage when the river is high. There is a small by-channel whose 

waters do not pass the gage but are measured at the bridge. The 

discharge at the higher stages has been estimated by extending 

the discharge curve.

TOPPENISH CREEK NEAR TOPPENISH, WASH.

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.

This station, which was established October 31, 1909, to aid the 

United States Reclamation Service in its general study of the water 

supply available for the development of the Wapato project, is located 

at Prahl's ranch, 4 miles south and 4 miles west of Toppenish. After 

leaving the hills this river spreads into innumerable sloughs, which 

traverse the plains, and it is almost impossible to find a point where 

all the flow can be measured.

The conditions at this station, although not favorable for refined 

results, are such that the entire flow is measured except during extreme high water, when a slough one-half mile south of the station 

will probably carry some water. The station was abandoned March 3, 

1909, in favor of a point just below the mouth of Simcoe Creek.

SATUS CREEK NEAR TOPPENISH, WASH.

Satus Creek, which drains the southern part of the Yakima Indian 

Reservation, unites with Yakima River about 8 miles below the 

mouth of Toppenish Creek.

This station 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, for which a knowledge of 

all streams draining the Yakima Reservation is of great importance. 

The station is located 4 miles west and 10 miles south of Toppenish, 

a short distance above the mouth of Dry Creek.

In general, conditions on this stream are not favorable for good 

results, but the station is located a short distance above a riffle control, where a stable relation between the gage heights and the flow 

can probably be determined. It is isolated, however, and very difficult to obtain continuous observations of gage heights, only weekly 

readings being possible at present.

CANALS IN YAKIMA VALLEY. 

NEW RESERVATION CANAL NEAR YAKIMA, WASH.

The New Reservation canal diverts water from the right bank of 

the Yakima River 6 miles below North Yakima and just below 

Union Gap.

The gaging station, which was established May 9, 1904, is located 

at a highway bridge 1,000 feet below the head-gate and above all 

diversions from 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 this canal.
YAKIMA EIVEE DRAINAGE BASIN. 193

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

The velocity of the water in the canal is slow, and on this account 

water grass grows profusely in the bed and on the banks of the canal, 

creating back-water conditions at the gage as the season advances. 

Several attempts have been made to get rid of this growth, as it 

interferes with the operation of the canal, but the attempts have 

been only partially successful. Discharges, therefore, must be obtained by the indirect method, which will give reasonably accurate 

results if a sufficient number of measurements are available.

The discharge at this station for 1908 has been added to that of 

the Old Reservation canal, the Sunnyside canal, and Yakima River 

at Wapato, to give the discharge of Yakima River at Union Gap, 

near Yakima.

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. There is 

a slough carrying considerable water that is taken into this canal at 

a point 280 feet below the head gate. It 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 waste way 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, but they represent the amount of water taken 

from the Yakima River. The discharges at the railroad bridge have 

been used to estimate the diversions from the Yakima River for 

May, June, November, and December, 1908, as the records at the 

intake do not cover these results.

Little choice was offered in the selection of the station, as the range 

where all the inflow could be measured above all diversions was only 

about 50 feet in length. The velocity at this point is sufficiently 

swift to prevent the growth of weeds, but it also has the effect of 

changing the channel when a large head is diverted into the canal. 

For the purposes for which the station was established the data are 

sufficiently accurate.

The data are valuable in connection with irrigation and also have 

an important bearing on the general hydrographic studies of the 

Yakima River system. The discharge at this station during 1908 

has been added to that of Sunnyside canal, the New Reservation
198 SUBFACE WATER SUPPLY, 1907-8.

canal, and Yakima River at Wapato, to obtain the discharge of 

Yakima River at Union Gap.

NOTE. The discharge at this station for July to October is about 90 per cent of that at the old station 

just below. The discharge has therefore been estimated as 230 second-feet for May and 186 second-feet for 

June. For November and December the discharge has been assumed to have been the same as at the old 

station.
YAKIMA RIVER DRAINAGE BASIN.

SUNNYSIDE CANAL NEAR WAPATO, WASH.o

201

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 500 feet below the intake, and above all deliveries.

The Sunnyside canal (PI. VI) was purchased by the United States 

Reclamation Service in July, 1906. It is at present somewhat over 

60 miles in length and irrigates nearly 42,000 acres of land. There 

are over 250 diversions from the main canal, one lateral Snipes 

Mountain being nearly 15 miles in length. In its general direction the canal parallels Yakima River, traversing the country at 

right angles to the drainage lines. 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 

laterals into beats, varying from 3 to 8 miles in length, each in charge 

of a patrolman. Gaging stations are maintained at the extremities 

of the beats, where the daily flow is obtained. 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 inclusion in this report, and only the quantity of water diverted 

from Yakima River as measured at the intake is presented in detail. 

A summary of the results obtained at other points on the canal is 

given and contains some very interesting data on evaporation and 

seepage (see below). Seepage investigations were made both on the 

main canal and on certain laterals especially chosen for that purpose.

Anew inclined gage was installed April 6, 1907, but the gage heights 

for this year 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 gage was installed just 

above this bridge and at a different datum. Measurements and gage 

heights for 1908 are referred to this gage.

the five months May to September, 1908.

o Discharges for October were omitted from 1906 report.

NOTE. Discharge for November', 1908, estimated. There may also have been a small amount of flow 

during December, 1908.
YAKIMA KIVER DRAINAGE BASIN. 205

KIONA CANAL NEAR KIONA, WASH.

This canal diverts water from the left bank of Yakima Kiver, 5 

miles upstream from Kiona, in sec. 10, T. 9 N., K. 20 E. It is operated by the Northern Pacific Irrigating Company. 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

EVAPORATION STATION AT LAKE KACHESS, WASH.

This station was established December 17, 1905, for the purpose 

of determining the evaporation from a water surface in this altitude. 

The records obtained here will doubtless be applicable to the other 

mountain lakes in this vicinity. The equipment consists of the 

usual evaporation pan with a sharp steel point in the center of the 

pan, the water surface being set at the level of the point at the time 

of each observation. Prior to June 11 the pan was anchored to a 

large rock in the middle of the lake about one-fourth mile above the 

outlet. On the latter date it was moved to a point near the outlet, 

where the water surface would not be subject to the wave action that 

interfered with the records at its former location. There is little 

difference in the atmospheric conditions at the two localities, and the 

records should be comparable.

EVAPORATION STATION AT ZILLAH, WASH.

During the seasons of 1907 and 1908 an evaporation pan has been 

maintained in the main Sunnyside canal at Zillah, Wash. This pan 

is of the usual pattern, observations being taken at intervals of two 

or three days and immediately after showers. The data obtained 

are believed to be as reliable as is possible with this method.

COLUMBIA RIVER DRAINAGE BASIN. 209 

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 Shoshone, 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, where it turns 

abruptly northward, forming 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 at 

Pasco Junction.

Practically all the large and most important tributaries of Snake 

River have their sources in the high mountains, which are heavily 

timbered. The heaviest timbered areas are those at the head of the 

South Fork in the Yellowstone Park region, the upper areas of the 

Teton, Fall, and North Fork of Snake rivers in southeastern Idaho, 

and those of upper Boise and Payette rivers in central Idaho.

Mean annual precipitation has a wide range throughout the Snake 

River drainage area. 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 past few years there has been considerable rainfall in this section 

and dry farming has been practiced successfully. In the valleys in 

the vicinity of Idaho Falls, Blackfoot, and St. Anthony, Idaho, the 

temperature 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 this drainage basin occurred in 1905. 

The wet years occurred in 1896, 1899, 1904, and 1907.

Snake River is noted for its many feasible storage sites, but only a 

very few have been developed. About 300,000 acre-feet can be stored 

at Jackson Lake by a temporary dam which has been installed by 

the United States Reclamation Service. The largest site is at Swan 

Valley on the South Fork of Snake, and the water available for 

11947 10 14
210 SURFACE WATER SUPPLY, 190*7-8.

storage is approximately 4,000,000 acre-feet. Feasible reservoir 

sites are also found on the North Fork of Snake, Fall, Teton, Boise, 

and Payette rivers. Most of these sites will, no doubt, be used at 

some future date by the United States Reclamation Service in connection with the Minidoka, Dubois, and Payette-Boise irrigation 

projects.

Although irrigation has reached a high stage of development in 

the Snake River valley, approximately 6,000,000 acre-feet of water 

annually run to waste. Eventually thousands of acres of arid land 

will be irrigated by the storage of these flood waters.

The water-power possibilities are almost unlimited, but only a few 

sites have been developed owing to the lack of market for power in 

large quantities. 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.

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, from which most of 

the drainage 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:

SNAKE RIVER. 

SNAKE RIVER NEAR BLACKFOOT, IDAHO.

This station is located at a wagon bridge 3£ miles north of Blackfoot, Idaho. Measurements were made during 1908 from the upstream side of the bridge. Measurements made during August, 1908, 

were affected by backwater and the gage readings bear no direct 

relation to the discharge, as during the period of these measurements 

a temporary diversion dam was being built across the river about 100 

yards below.

212 SURFACE WATER SUPPLY, 1907-8.

SNAKE RIVER AT NEELEY, IDAHO.

This station, which was established March 17, 1906, in order to 

obtain a record of the discharge of Snake Kiver above the Minidoka 

and Twin Falls irrigation projects, is located at Bennion's ranch, onehalf mile north of the Neeley post-office, Idaho, 4 miles west of American Falls, the nearest railway point, and 3 miles above the backwater 

from the Minidoka dam.

Port Neuf Kiver joins the Snake about 5 miles above the station, 

and Kaft Kiver, which is very small, enters about 10 miles below.

Eighty-four canals, most of them in the vicinity of Blackfoot and 

Idaho Falls, Idaho, divert water from Snake River above this station. 

When these channels are diverting all the water in the river, and the 

channel is dry for a distance of 10 miles near Blackfoot, Idaho, a flow 

of about 2,000 second-feet is formed at the Neeley station. This 

water comes from springs in the river channel for a distance of 20 miles 

above the station.

The velocity of the current is rather low during all stages. The bed 

of the river at this point is permanent, being composed of solid rock. 

The gage heights are not affected by logging or artificial control above 

and seldom by ice. The gage datum has remained unchanged since 

the station was established.

SNAKE RIVER DRAINAGE BASIN. 215

SNAKE RIVER NEAR MINIDOKA, IDAHO.

This station was originally established August 3, 1895, at Montgomery's ferry, on the stage road from Minidoka to Albion, 4 miles 

east of Rupert, Idaho, and 10 miles below the diversion dam for the 

Minidoka irrigation project. Measurements at Montgomery's ferry 

show the amount of water available for irrigation there and for the 

newly constructed Twin Falls canals heading 23 miles below, and 

indicate also the conditions that will exist for power development at 

Shoshone Falls, about 45 miles below, after the irrigable lands of 

Snake River valley shall have been reclaimed.

The nearest tributary above the station is Raft River, which enters 

the Snake from the west about 18 miles above. No important tributaries enter below the station for a distance of 40 miles.

The low-water discharge at this station falls below 2,000 secondfeet during the latter part of July and August in dry years. The 

Twin Falls irrigation canals divert about 25 miles below and their 

water right calls for 3,400 second-feet, while the Minidoka project 

(PL VII, -B), which diverts 12 miles above the station, has a water 

right of 2,000 second-feet. The deficiency during low water is supplied by stored water from Jackson Lake, Wyoming.

The records are somewhat affected by ice during January and 

February, and some irregularity of flow is caused by the changing of 

gates at the Minidoka dam 12 miles above.

The gage datum has remained unchanged since August 28, 1905.

The records at this station are very good. The cross section is 

permanent and a good rating curve has been obtained.

NOTE. Discharges have been computed, using the 1906 rating for medium and low stages. The two 

measurements made in 1907 and 1908 plot about 5 per cent smaller than this curve, but the channel is 

believed to be permanent. These values are subject to revision should further data confirm the later 

measurements.

JACKSON LAKE NEAR MORAN, WYO.

Jackson Lake is situated just east of the Idaho-Wyoming state 

line, a short distance south of the Yellowstone National Park. It is 

drained by the South Fork of Snake River. Its storage possibilities 

have been developed by the construction of a dam near the lake 

outlet.

SOUTH FORK OF SNAKE RIVER AT MORAN, WYO.

This station, which was established September 21, 1903, to determine the amount of water available in Jackson Lake, is located 

directly back of the post-office at Moran, Wyo., and about threefourths of a mile below the outlet of Jackson Lake.

There are no diversions above the station, which lies between 

Pacific Creek and the outlet of the lake, and the record covers only 

the water that flows from the lake.

The records are not affected by logging or ice conditions, but a 

temporary dam has been installed at the lake by the United States 

Reclamation Service and the daily flow at the station is affected by 

the raising and lowering of the gates at the dam. The annual runoff, however, is not affected.

The gage datum has remained unchanged since the station was 

established.

As the cross section is permanent a very good rating curve has 

been obtained and the records may be considered very reliable.

SOUTH FORK OF SNAKE RIVER NEAR LYON, IDAHO.

This station, which was established April 18, 1903, in order to 

determine the water available for storage at the Swan Valley reservoir 

site, 2 miles above, is located on the old site of Wedekind's ferry, 

between Lyon and Swan Valley, at the upper end of Conant Valley.
SNAKE RIVER DRAINAGE BASIN. 221

No tributaries enter below this station, and the records therefore 

show the run-off for the entire drainage basin of the South Fork of 

Snake River. The main tributaries above are Salt, John Day, 

Hobacks, Gros Ventre, and Buffalo rivers.

No water is diverted above the station except for a few shoestring 

ranches along the river.

The gage heights are not affected by logging operations, but are 

affected by ice during the winter months, and the daily flow shows 

somewhat the effect of the raising and lowering of the gates at the 

Jackson Lake reservoir above.

A new gage was set October 16, 1904, about 1 mile above the gage 

first installed, and the gage datum has remained unchanged since that 

time.

The cross section is permanent and a good rating has been obtained. 

The records may be considered very reliable.

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 South Fork.

The gaging station, which was established August'20, 1902, to 

determine the amount of water available for storage purposes above, 

after deducting the amount already appropriated for irrigation, is 

located at North Fork Bridge, 2 miles south of Or a and 10 miles above, 

St. Anthony, Idaho.

Teton and Fall rivers enter below the gaging station, the Teton 

coming in about 3 miles above the junction of the North Fork with 

the South Fork of Snake River. Above the gaging station the principal tributaries are Robinsons Creek and Warm River. No water 

is diverted for irrigation above the station. The river is subject 

to no artificial control above and is too shallow for logging.

The gage datum has remained unchanged since the station was 

established.

The records are fair during high water and good during low water, 

some inaccuracy being due to changes in the channel. Gage heights 

are affected only slightly by ice conditions.

226 SUEFACE WATEK SUPPLY, 1907-8.

FALL RIVER AT FREMONT, IDAHO.

Fall River rises in the southwestern part of Yellowstone National 

Park and flows westward, uniting with the North Fork of the Snake 

near Chester, Idaho.

A gaging station was established January 1, 1904, about 900 feet 

from Fremont post-office, in order to determine the amount of flood 

water available for storage in the Fall River meadows.

As the river receives no important tributaries below the station, 

the records show practically the total run-off from the Fall River 

drainage area. One comparatively small irrigation canal diverts 

above the station.

The records are not affected by logging or artificial control of the 

water above, but are affected by ice during the winter months.

The gage datum has remained unchanged since the station was 

established.

The cross section is rather rough, but is permanent, and a good 

rating curve has been obtained. The records may be considered 

reliable for open channel conditions.

TETON RIVER NEAR ST. ANTHONY, IDAHO.

Teton River is the most important tributary of the North Fork of 

the Snake, rises in the Teton Mountains south of the Yellowstone 

National Park, and flows westward uniting with the North Fork 

about 8 miles southwest of St. Anthony, Idaho.

The gaging 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, Idaho.

No tributaries enter below the station, but the flow is affected by 

tributaries and a canal above the station and the records should 

therefore be used carefully.

The gage heights are not affected by logging or artificial control 

above, but are somewhat affected by ice during the winter months.

The gage datum has remained unchanged.

A good rating curve has been obtained and the records may be 

considered reliable.

SNAKE RIVER DRAINAGE BASIN. 231

BLACKFOOT RIVER 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 southwestward 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 ROSSFORK, IDAHO.

This station, which was established July 15, 1908, to determine 

the amount of water available for storage at the reservoir at Blackfoot Marsh, now under construction by the Indian Service, 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. The discharges at this station can not yet be computed.

BLACKFOOT RIVER NEAR PRESTO, IDAHO.

This station, which was established April 17, 1903, to determine 

the flood waters available for storage, is located on the ranch of 

James Just, 2 miles west of Presto and about 15 miles from Blackfoot, Idaho.

No tributaries enter below the station and the tributaries above 

are small streams flowing 10 second-feet or less. Two irrigation 

canals divert above the station.
232 SUBFACE WATER SUPPLY, 190*7-8.

The records are not affected by logging or artificial control above, 

but are affected by ice during the winter months.

The gage datum has remained unchanged since the station was 

established.

The cross section is nearly permanent and a fair rating curve 

has been obtained. The records may be considered good.

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.

This station, which was established April 25, 1904, discontinued 

August 31, 1906, and reestablished July 1, 1907, is located at 

Howell's ranch, the last one on the left bank, about 25 miles upstream from Mackay, Idaho, 7 miles from Chilly, and 3 miles above 

Kinickinick Point.

The object of the station is to determine the amount of water 

available for storage at the reservoir site 3 miles above Mackay.

Until April 20, 1906, the gage was located one-fourth mile from 

the ranch. It was moved in order to place it on the main channel.

The stream receives no tributaries of any importance below the 

station. One small irrigation ditch diverts above the station.

The gage heights are not affected by logging or artificial control 

above the station, but ice prevails to such an extent that it is necessary to discontinue readings for about three months in the winter.

The channel section is permanent and a good rating curve has 

been obtained. The records may be considered reliable.
236 SURFACE WATER SUPPLY, 1907-8.

The following measurement was made October 4, 1907:

Width, 80 feet; area, 140 square feet; gage height, 2.50 feet; discharge, 207 secondfeet.

Daily gage height, in feet, of Big Lost River near Chilly, Idaho, for 1907 and 1908.

NOTE. The 1906 rating table is believed to apply fairly well to these gage heights, but as the only measurement made in 1907-8 plots 12 per cent smaller than this table, no discharges have been computed.
SNAKE EIVEE DRAINAGE BASIN. 237

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 point of junction with Snake River in the western part 

of Lincoln County. It is about 100 miles long and drains an area 

about 4,500 square miles in extent. It receives a numberof tributaries, 

the most important being Camas Creek and Little Wood River.

The gaging 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 data obtained are 

used to determine the amount of water available for storage at this 

reservoir.

Little Wood River joins Big Wood River about 15 miles below 

the station, and the main tributary is Camas Creek about 26 miles 

above.

A reservoir dam is now under construction at the Cottonwoods, 

15 miles above, where the whole flow of the river will be stored for 

the irrigation of a tract east of Shoshone, Idaho.

The records are not affected by ice, logging, or artificial control 

above.

The gage datum has remained unchanged since the station was 

established.

The cross section is permanent and a good rating curve has been 

obtained. The records may be considered very reliable.

SNAKE RIVER DRAINAGE BASIN. 239

SUCCOR CREEK NEAR HOMED ALE, 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.

The 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 one-half 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.

The station is below all tributaries and diversion canals. The 

entire low-water flow is diverted and used for irrigation above.

Gage heights are affected only by changes in the channel. The 

cross section is not permanent and a new rating must be obtained 

each year. The records are only fair.

OWYHEE RIVER BASIN. 

DESCRIPTION.

Owyhee River rises in the Independence Forest Reserve 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., exactly opposite the mouth of Boise River in Idaho. The total 

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 and the trees are those characteristic of arid sections. 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 a considerable 

period during the winter months, so that records for this part of the 

11947 10 16
242 SUEFACE WATER SUPPLY, 1907-8.

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 the Owyhee and Malheur rivers. On the upper 

portions of the river conditions are favorable for impounding the 

flood and winter flows for irrigation during the summer months; but 

as the region is without transportation facilities, very little is known 

concerning its topography, geology, or hydrography.

One gaging station has been maintained in this drainage basin and 

that at the mouth of the river. Records have been obtained at this 

point (1890 to 1896 and 1903 to 1908).

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 one-half mile from Owyhee post-office and 3 miles 

above the mouth of the stream.

The data have practical value in connection with irrigation development and have also scientific interest, as they may be used to 

determine the run-off factors applicable to large arid areas without 

timber.

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 waste 

ways 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 in 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 icebound 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. 

The rating curve is permanent, as the flow is controlled by a riffle 200 

yards below the station. Conditions are favorable for good results, 

and the records are believed to be reliable.

SNAKE RIVER DRAINAGE BASIN. 245

BOISE TMVER BASIN. 

DESCRIPTION.

Boise River rises in the western part of Blaine County and flows 

westward across Elmore, Ada, and Caldwell counties to its junction 

with Snake River. Its drainage area is mountainous and well 

wooded.

BOISE RIVER NEAR HIGHLAND, IDAHO.

This station wTas established July 27, 1905, to replace the Boise 

station. It is located 2 miles below the mouth of Moores Creek, 3 

miles southwest of Highland post-office, about 8 miles above the old 

Boise station, and 15 miles east of Boise, the nearest railroad point.

The object of the station is to determine the amount of flood waters 

available. The records have proved to be very valuable in connection with the distribution of the low-water flow, which is all used for 

irrigation. Moores Creek enters the river 2 miles above the gaging 

station; no tributaries come in below. There are no diversions above 

the station.

The gage heights are somewhat affected by ice during the winter 

months, and the daily flow may also be affected by flushing during 

the logging season.

The gage datum has remained unchanged during 1908.

The cross section is permanent and a good rating curve has been 

obtained. The records may be considered very reliable.

SEEPAGE INVESTIGATIONS ON BOISE RIVER.

Investigation of the amount of seepage water returning to Boise 

River between the mouth of the canyon 8 miles above Boise and the 

highway bridge 1^ miles above Caldwell were made August 5 11, 

1907, and September 19-25, 1908. The work was done on foot by 

following the river channel and keeping close to the water's edge, so 

that the discharge of every canal and natural stream could be obtained. The flow of large streams was measured and that of small 

ones was estimated.

Between the canyon and the Highland gaging station, 8 miles 

upstream, the river flows through a narrow, rocky gorge, and there 

is practically no loss or gain.

The net seepaga is the difference between the discharge of the 

river at the upper point plus all the tributaries between the two 

points of measurement and the discharge of the river at the lower 

point plus all the diverted water between the two points in question.

RESULTS IN 1907.

On August 5, 1907, the gage at Highland read 5.2 feet, showing a 

discharge, according to the rating table, of 2,150 second-feet; on 

August 12 the gaging showed 1,689 second-feet, with gage at 4.65 

feet; these figures indicate a decrease of 461 second-feet during the 

period covered by the study. By taking 1,920 second-feet as the
SNARE RIVER DRAINAGE BASIN. 249

discharge at the mouth of the canyon, the necessary allowance is 

made for the decrease in discharge.

The summer of 1907 was one of the wettest ever known to the 

irrigators in the Boise Valley, and the discharge was almost double 

that for the same period during previous }T ears.

The results ma}7 be tabulated as follows:

RESULTS IN 1908.

On September 19, 1908, a gaging was made at the Highland station. The gage was at a height of 3.90 feet, giving a discharge of 

1,255 second-feet. On September 25 the gage had dropped to 3.5 

feet and the result of gaging gave a discharge of 880 second-feet. 

The average of the two gagings was 1,068 second-feet, which was used 

as the average discharge at the mouth of the canyon, which is about 

8 miles below the gaging station.

The results, tabulated, are as follows:

PAYETTE RIVER 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.

a Mistakes were found in calculation. The result of 255.3 serond-feet as published in Water-Supply 

Paper No. 100 should read 139.6 second-feet.
SNAKE RIVER DRAINAGE BASIN. 253

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.

NORTH FORK OF PAYETTE RIVER AT LARDO, IDAHO.

The North Fork of Payette River rises in Big Payette Lake, flows 

southward, and unites with the main stream near Pinehurst.

The gaging station, which was established August 25, 1908, to 

obtain a record of the amount of water available for storage on Big 

Payette Lake, is located about one-fourth mile below the lake outlet 

and the same distance from Lardo, Idaho.

The equipment consists of a vertical staff gage and a cable and car. 

The discharge can not be computed until more data are available.

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
254 SURFACE WATEK SUPPLY, 1907-8.

Horseshoe Bend post-office, Idaho, and about 32 miles from Boise, 

the most convenient railway point.

There are no tributaries below the gaging 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 irregularity of 

flow is caused by flushing during the logging season in June and 

July. This, however, only affects the daily discharge and not the 

monthly run-off.

The gage datum has remained unchanged and the records are good.

MALHEUR RIVER 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 sage brush, and 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 land 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 conjoined large storage possibilities, ample stream flow, and 

enormous areas of desert lands. The United States Reclamation
SNAKE BIVER DKAINAGE BASIN. 257

Service has under consideration a project which contemplates the 

construction of reservoirs on the headwaters of the Malheur and its 

principal tributaries.

The following gaging stations have been maintained in this river 

basin:

Malheur River at Halliday's bridge near Ontario (1904 to 1905).

Malheur River at Vale (1890 to 1896 and 1903 to 1908).

Malheur River at McLaughlin's bridge near Vale (1904 to 1906).

Malheur River near Westfall (1903 to 1905).

Willow Creek at Dell (1904 to 1906).

Willow Creek near Malheur (1904 to 1906).

Bully Creek at Vale (1904 and 1905).

Bully Creek at Warm Springs (1905 to 1907).

Middle Fork of Malheur River at Riverside (1906 and 1908).

During the period covered by these records, the flow of the Malheur appears to have been greatest in 1904 and lowest in 1895. The 

earlier records are not as dependable as those of later years.

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. 

Since the latter date they were interrupted only 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 

2^ 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 th.3 stream are extensively used for irrigation, the low-water flow 

being entirely appropriated for this purpose. Unfortunately measurements do not show the natural flow of the stream because of diversions for irrigation above. During 1904 and 1905, while the Malheur project was under investigation by the United States Reclamation Service, measurements were made during the irrigating season of 

the more important ditches. The following table gives the principal 

canals, the location of the head-gate, and the maximum amount 

diverted, as shown by measurements taken in 1904 and 1905:

Any future development must involve the construction of roservoirs on the headwaters of the stream.

During the winter months the records of flow are rendered somewhat inaccurate by ice conditions. As the bed of the stream is 

composed of shifting sand, a permanent rating curve can not be 

obtained. Unless a number of measurements are made each season 

it is impossible to prepare reliable estimates of flow.

MIDDLE FORK OF MALHEUR RIVER AT RIVERSIDE, OREG.

This station, which was established January 3, 1906, was abandoned 

March 7, 1907, because'of its inaccessibility and the impossibility of 

getting a sufficient number of measurements except at an excessive 

cost. It was, however, reestablished on December 15, 1908, and is 

being maintained at the present time. It is located one-half mile 

above Riverside post-office, which is reached by stage 125 miles from
260 SURFACE WATER SUPPLY, 1907-8.

Vale. It is 200 feet above the mouth of the Malheur River. A srasre

O O

was also installed on the Middle Fork of the Malheur about one-half 

mile below the mouth of the South Fork, where measurements are 

made in conjunction with those at the regular stations above.

The data obtained here will be chiefly of value in determining the 

storage possibilities on this river for irrigation.

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

The bed of the stream is composed of sand and gravel and changes 

at every freshet. During the winter months the river freezes and ice 

gorges frequently form, which back water above the gage.

BULLY CREEK NEAR VALE, OREG.

This station, which was first established August 10, 1903, was 

destroyed by flood and discontinued March 11, 1904, in favor of a 

station at the mouth of the creek. It was again established January 

29, 1905, and maintained until March 31, 1907, when it was discontinued for lack of funds. It was located 13 miles above the mouth 

of the creek and 2 miles below the mouth of Cottonwood Creek.

The data obtained have considerable value, for the creek affords 

storage facilities important to the development of irrigation in the 

Malheur basin.

The conditions at the station have never been favorable for good 

results, and dependable estimates of discharge can be made only when 

it is possible to secure a large number of measurements throughout 

each season.

POWDER RIVER BASIN. 

DESCRIPTION.

Powder River, which drains the eastern slope of the Blue Mountains, rises in the extreme western portion of Baker County, flows 

west, then north through Baker City to the town of North Powder,
262 SURFACE WATER SUPPLY, 1907-8.

where it turns abruptly to the southeast and empties into the Snake 

River in the east central part of Baker County.

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 winter as 

the streams are icebound for weeks at a time.

The lowest run-off from this basin since records have been kept 

occurred in 1905; the highest occurred in 1904, but 1907 was a close 

second.

Only one gaging station has been maintained in this basin that 

at Salisbury.

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 has of recent years been logged off.

During the winter months the stream frequently remains frozen 

for long periods, and although an attempt has been made to develop 

rating curves for ice conditions, the results have not been very 

satisfactory.

GRANDE RONDE RIVER BASIN. 

DESCRIPTION.

Grande Ronde River, which 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
266 SURFACE WATER SUPPLY, 1907-8.

the Blue Mountain Range), rises on the divide in the extreme southern portion of Union County, flows in a generally northeasterly direction and empties into Snake River at Zindel, Washington, about 

12 miles from the point where the Snake crosses the Oregon-Washington line. The principal tributaries of the Grande Ronde are 

Joseph Creek, which drains the Chesnimnus Forest Reserve, the Wallowa, which rises in the Powder Mountains and drains the Wallowa 

Forest Reserve, 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 

forest reserves. 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 practiced 

to an elaborate extent, although exceptionally good possibilities 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 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. The year 1905 was a "dry year" and all streams in the 

basin carried less quantities of water than during other years covered by the records. The year 1907 was a "wet year."

The following gaging stations have been maintained in this drainage 

basin:

Grande Ronde River at Hilgard, Oreg. (1903 to 1908). 

Grande Ronde River at Elgin, Oreg. (1903 to 1908). 

Grande Ronde River at Zindel, Wash. (1904 to 1908). 

Catherine Creek near Union, Oreg. (1907). 

Wallowa River near Joseph, Oreg. (1903 to 1908). 

Wallowa River near Wallowa, Oreg. (1903 to 1907). 

Wallowa River near Elgin, Oreg. (1903 to 1908).
SNAKE BIVEft DRAINAGE BASIN.

GRANDE RONDE RIVER AT HILGARD, OREG.

This station, which was established November 6, 1903, is located 

one-half mile below Hilgard station, on the Oregon Railroad and Navigation line, and just below the mouth of Five Points Creek, which is 

the most important tributary above the Grande Ronde Valley.

The data obtained here are necessary to determine the quantity of 

water available for irrigation in Grande Ronde Valley, at the head 

of which the station is located.

At this point the river is chiefly used for the transportation of logs, 

and 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 are grounded on the bars below the station 

and even in the cross section where measurements are made, producing back-water influence.

Gage heights for 1906 were omitted from Water Supply Paper 

No. 214 as they were considerably affected by backwater from log 

jams. It is now believed that this obstruction existed for only a 

small portion of the year, and as such periods are fairly well covered 

by discharge measurements and observer's notes, discharges have 

been recomputed, making proper allowance for backwater.

a- This table is based on 10 discharge measurements made during 1904-1907, and is fairly well defined 

between gage heights 2.7 feet and 5.0 feet. Below gage height 3.5 feet it is not applicable for ice or obstructed-channel conditions; above this it is somewhat smaller than the open-water table to allow for 

the obstructed conditions generally existing during high-water periods.

b This table is based on 4 discharge measurements made during 1906-1908, all of which are believed 

to have been made under partially obstructed-channel conditions similar to those that existed during 

1908. It is fairly well defined between gage heights 3.0 feet and 4.9 feet, but is-very uncertain below 

that. Above gage height 4.8 it is the same as the 1906 and 1907 table.

NOTE. The following correction has been made to discharges to allow for obstructed channel conditions:

1906: March 8 to 11, based on measurement of March 10; March 19 to 21, interpolated on account of ice; 

May 14 to 31, based on a rating curve through measurement of May 16; June, taken as two-thirds the openchannel discharge as indicated by measurement of June 22; December 1 to 6, based on measurement of 

December 4, on account of ice.

1907: January 7 to February 4, estimated 250 second-feet; February 5 to 8, 840 second-feet, on account 

of ice; March 14 to 20, 0.6 foot subtracted from gage height before applying table; March 21, based on gage 

height of 5.6 feet, taken after the logs went out.

The observer makes no note of logs after May 1, 1907, so that no corrections can be made after that date, 

and the records are more liable to error than before that date. The discharge at this station has been compared with that at Elgin below, and the ratios obtained indicate that the results are fairly reliable as a 

whole, but that those for the early part of 1908 are probably somewhat too large.

GRANDE RONDE RIVER AT ELGIN, OREG.

This station, which was established November 20, 1903, is located 

at the lower end of Grande Ronde Valley, within the city limits of 

Elgin, above the mouth of Clarks Creek and below the mouth of 

Indian Creek. The datum of the chain gage has not been changed 

since its instaljation.
SNAKE RIVER DRAINAGE BASIN. 271

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 

Konde Valley.

The conditions at the station are not at all 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 estimates published herewith are only fairly accurate.

a Discharges interpolated December 16 to 27, 1907, and January 31 and February 1 and 13, 1908. 

GRANDE RONDE RIVER AT ZINDEL, WASH.

This station, which was established June 30, 1904, is located 2 

miles above the mouth of the stream, 1| miles below Joseph Creek. 

Its records show the quantity of water contributed to Snake River 

by the Grande Ronde drainage basin.

The data obtained are chiefly of scientific interest in connection 

with a general study of run-off factors from such forested areas as 

are found in the Blue Mountains.

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, and it is hoped that a sufficient number of ratings 

can be made in the future to develop this curve and thereby obtain 

an estimate of the flows for the years covered by gage records.

CATHERINE CREEK NEAR UNION, OREG.

275

This station, which was established May 15, 1906, is located in 

a canyon one-half mile below Robbins's sawmill, 6 miles above 

Union, and above all diversions for irrigation, but below the intake 

of the water-supply pipe for the city of Union. A small dam about 

one-fourth mile above the station is used lay a mill.

Reliable records obtained at this point would be of great economic 

importance. The stream has a well-maintained flow throughout 

the irrigating season, but is nearly all used for irrigation during the 

summer months. An additional supply is possible only by the 

construction of storage reservoirs.

During the winter months the water at the station freezes from 

the bottom, forming anchor ice, and the records during this period 

of the year are therefore not to be depended upon. During the 

summer months the flow obtained at the station is more or less 

irregular, because of the nonuniform use of water at the mill above. 

As it was impossible to obtain continuous gage observations, the 

station was abandoned May 19, 1907.

The following measurement was made April 30, 1907.

Width, 39 feet; area, 67 square feet; gage height, 3.20 feet; discharge, 302 secondfeet.

WALLOWA RIVER NEAR JOSEPH, OREG.

This station, which was established November 12, 1903, is located 

500 feet below the outlet of Wallowa Lake, li miles above Joseph. 

Four large irrigation ditches divert a large portion of the stream, 

the highest one heading about 500 feet below the station. A timber 

dam at the outlet of Wallowa Lake is jointly 'owned and operated 

by the managers of the irrigation ditches.

The data obtained here have practical value in connection with 

irrigation development and have also scientific interest in connection 

with the determination of run-off values from the forested areas of 

the Powder River Mountains.

The bed of the stream is composed of coarse gravel and bowlders 

and is very rough. Individual measurements of flow can not be 

made with great accuracy, and changing channel conditions have 

made it impossible to develop a permanent rating curve. The 

results thus far obtained are not as accurate as could be desired.

WALLOWA RIVER NEAR WALLOWA, OREG.

This station, which was established November 14, 1903, was 

abandoned March 31, 1907, as it was impossible to obtain continuous gage observations and as the record did not show the flow of the 

stream at critical points. It was located one-fourth mile below 

the mouth of Bear Creek and 1£ miles from Wallowa, in the midst 

of an irrigated valley. Diversions are numerous above and below 

this point and a small irrigation ditch diverts water from the right 

bank about 300 feet above the station. During the winter months 

the stream is subject to ice conditions which greatly affect the determination of flow.

The following measurement was made May 4, 1907:

Width, 83 feet; area, 150 square feet; gage height, 2.50 feet; discharge, 669 secondfeet.

WALLOWA RIVER NEAR ELGIN, OREG.

This station, which was established November 18, 1903, is located 

near Minam station, on the extension of the Elgin branch of the 

Oregon Railroad and Navigation Company's line just below the 

mouth of Minam River and 9 miles below the lower end of the Wallowa 

Valley.
SNAKE EIVEB DEAINAGE BASIN. 279

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.

It has been difficult to obtain continuous observations at this 

point, and the records are therefore somewhat broken. During the 

winter months ice conditions affect the results to a considerable 

degree, and the winter records are not as reliable as could be desired. 

Occasionally ice gorges form below the station, which back the water 

above the gage. The flow of the stream is, however, fairly uniform.

a Ice conditions for 1907 as follows: First freeze January 4, depth of ice 4 inches. This ice went out 

January 15 and formed an ice gorge which caused the high gage height on this date. From January 27 to 

February 5 the river was frozen about two-thirds over and solid about the gage.

PALOUSE RIVER BASIN. 

DESCRIPTION.

Palouse River rises in the northern part of Lattah County, Idaho, 

on the divide between the Spokane and Snake River drainage, 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 the Palouse is Rock Creek, which drains 

a number of small lakes in the northern part of Whitman County. 

The agricultural lands consist chiefly of rolling table-lands, largely 

utilized for the production of wheat. No forests of magnitude are
SNAKE RIVER DRAINAGE BASIN. 281

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 area is well adapted to irrigation agriculture, although 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 of magnitude 

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 the outlets of such 

coulees will develop storage reservoirs of great 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.

The year 1905 is the "dry year" of the records and 1901 the "wet 

year."

The following gaging stations have been developed in this drainage 

basin:

Palouse River at Hooper (1897 to 1908). 

Palouse River at Elberton (1904 to 1905). 

Cow Creek at Hooper (1904). 

Cow Creek at Keystone (1904 to 1905). 

Rock Creek near St. Johns (1903 to 1905).

PALOUSE RIVER AT HOOPER, WASH.

This station, which was established April 1, 1897, is located 1 mile 

above the mouth of Cow Creek.

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 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.

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. From April 21, 1907, to June 14, 1908, no observations 

were taken, but as this period did not include critical stages of the 

river, and as the records cover a long period, the omission is not as 

serious as it might be. The datum of the present gage is 1,053.42 

feet above sea level.

WALLA WALLA RIVER DRAINAGE BASIN. 

DESCRIPTION.

Walla Walla River rises on the western slope of the Blue Mountains 

and flows westward into the Columbia. Its drainage area lies immediately north of that of the Umatilla 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. 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, and that 

in the manner characteristic of the Blue Mountains. The lower half 

is given to the production of wheat without irrigation, while 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.

On the headwaters of the stream very favorable opportunities for 

the development of water power and storage facilities are found 

which, if developed, would more than double the value of this stream. 

The entire low-water flow of the river is appropriated many times 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.

The following gaging stations have been maintained in this river 

basin:

Walla Walla River at Whitman, Wash. (1897 to 1899).

Walla Walla River near Milton, Oreg. (1903 to 1908).

South Fork of Walla Walla River near Milton, Oreg. (1903 to 1908).

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 W^est 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.
286 SURFACE WATER SUPPLY, 1907-8.

It has been impossible to find a point where the records would not 

be complicated by diversions for irrigation, as the waters of the stream 

are appropriated many times over during the summer.

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 

between floods. A number of gages and gaging equipments have 

been washed away during these excessive floods, and at such times 

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.

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.

The flood of May 30, 1906, changed the channel of the river and 

left the gage high and dry. On August 10 of that year a new station 

was established one-fourth mile above the headgate of the Northwest 

Gas and Electric Company'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
288 SURFACE WATER SUPPLY, 1907-8.

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 were 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, but an insufficient number 

of measurements between floods will make estimates correspondingly 

inaccurate. The highest discharge recorded since the station was 

established is 1,660 second-feet, April 14, 1904, but this value, however, does not nearly represent the flood discharge at this point. 

For low-water 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, but there are also some contributions from intermediate drainage.

UMATILLA RIVER DRAINAGE BASIN. 

DESCRIPTION.

Umatilla River rises in the northeastern corner of Umatilla 

County, Oreg., and flows generally westward a distance of 80 miles, 

emptying into Columbia River at the town of Umatilla. The area 

above the town of 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 Meachum 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 quite heavily forested, but downstream the forests 

give place to rolling table-lands devoted to the production of wheat. 

The immediate valley of the river has been irrigated for many years, 

and the entire low-water flow of the stream is appropriated for irrigation. The United States Reclamation Service has completed a 

project to irrigate about 20,000 acres near Hermiston (PI. VII, A). 

The soil of this portion of the drainage basin is sandy and the climatic

conditions are favorable for the production of fruit. The highest 

run-off obtained since records have been kept occurred in 1899 and 

the lowest in 1906.

The following gaging stations have been maintained in this drainage 

basin:

Umatilla River near Umatilla (1904 to 1908).

Umatilla River at Yoakum (1903 to 1908).

Umatilla River at Pendleton (1891 to 1892 and 1903 to 1905).

Umatilla River at Gibbon (1896 to 1908).

McKay Creek near Pendleton (1903 to 1904).

TJMATILLA RIVER AT GIBBON, OREG.

This station was established July 22, 1896, and has been maintained continuously since that date except for certain intervals when 

an observer was not available or when the gage equipment had been 

washed away by flood. The records of the flow at this station are 

of particular value, as the waters are entirely used in the lower valleys for irrigation, and at this point the river affords some exceptional advantages for water-power development. The station is 

located on the Umatilla Indian Reservation, 1 mile below Gibbon 

post-office, about 1^ miles below the mouth of Meacham Creek, and 2 

miles above the mouth of Squaw Creek.

The river here is subject to sudden and violent floods, and it has 

been impossible to establish a permanent rating curve. The bed of 

the stream throughout its course is composed of coarse gravel, and 

the river has a flood plain from 100 to 500 feet in width. When these 

floods occur, the appearance of the locality is changed almost beyond 

recognition. Gage after gage has been washed away and a number 

of gaging cables have been destroyed. Under such conditions the 

maintenance of a permanent gage datum is of no consequence and the 

station has to be rerated after each destructive flood. The actual 

quantity of water carried at the crest of the flood at such times can 

not be determined, because the maximum change in the channel is 

then taking place.

For the reasons above stated the records at the station have been 

intermittent, but estimates of the flow during the interval of interruption have been made, either from the facts obtained from local 

authorities or by comparison with other stations farther down stream, 

whenever it could be done with a reasonable degree of accuracy.

UMATILLA RIVER AT YOAKUM, OREG.

This station, which was established May 5, 1903, is located 18 miles 

below Pendleton, 1^ miles east of the Yoakum station of the Oregon 

Railroad and Navigation Company. No tributaries enter in the
294 SURFACE WATER SUPPLY, 1907-8.

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 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.

a Discharge of March 14 estimated at 16,000 second feet. 

UMATILLA. RIVER NEAR UMATILLA, OREG.

This station, which was established October 21, 1903, in order to 

determine the quantity of water flowing into Columbia River after 

the irrigation requirements had been satisfied, is located 1^ miles 

above the mouth of the river near the town of Umatilla, one-fourth 

mile below the diversion point of the Oregon Land and Water 

Company's canal, and one-fourth mile above the headgate of the 

Brownell ditch.

The conditions at the station are favorable for excellent results. 

The bed and banks of the stream for the half mile above and below 

the station are of solid rock, and an absolutely permanent rating 

curve has been obtained. The velocity of the water at this point is 

sufficiently rapid to prevent the deposit of silt or sand in the vicinity 

of the station, and even at extreme floods the water is all confined 

within the banks of the stream.

JOHN DAY RIVER DRAINAGE BASIN. 

DESCRIPTION.

John Day River, which drains the country to the northwest of the 

Blue Mountains, rises on the divide between Grant and Baker counties, Oreg., flows westward and then northward and joins the Columbia about 28 miles above The Dalles. Its principal tributaries are 

are the North, Middle, and South forks. Its total drainage area 

includes 7,800 square miles. The general elevation of its headwaters 

is about 6,000 feet above sea level; at Fossil the elevation is about 

1,500 feet.

Only the headwater region of the stream is forested, the greater 

part of the basin being utilized as range for sheep and cattle or for the 

growing of wheat by the "dry farming" process.
300 SURFACE WATER SUPPLY, 1907-8.

The mean annual rainfall varies from 24 inches on the headwaters 

to 10 inches at the mouth. The winters are cold, and trie streams are 

frequently icebound throughout the greater part of the winter. 

Except wheat, which is raised on the rolling uplands, 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. Since records have been kept, the highest 

run-off occurred in 1907 and the lowest in 1905.

The following gaging stations have been maintained in this river 

basin:

John Day River near Dayville (1908). 

John Day River at McDonald (1904 to 1908). 

South Fork of John Day River at Dayville (1908). 

Rock Creek near Arlington, Oreg. (1905).

JOHN DAY RIVER NEAR DAYVILLE, OREG.

This station, which was established November 23, 1908, is located at 

McRae's ranch, 3 miles above Dayville, and 3 miles above the mouth 

of the South Fork of the John Day River.

The data obtained here will be valuable chiefly for the study of the 

possibilities of irrigation from this stream by means of storage, as a 

number of excellent reservoir sites are found on the river above this 

point.

The following measurement was made November 23, 1908:

Width, 40 feet; area, 62 square feet; gage height, 0.55 feet; discharge, 154 secondfeet.

Daily gage height, in feet, of John Day Rirer near Dayville, Oreg., for 1908.

JOHN DAY RIVER DRAINAGE BASIN. 301

JOHN DAY RIVER AT MCDONALD, OREG.

This station, which was established December 16, 1904, 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.

The results obtained at this station are of considerable economic 

importance, as the stream will be used for both water power and irrigation. 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 disturbed for 

short periods by ice conditions, but it is thought improbable that the 

reliability of the results has been affected to any important degree. 

The general conditions at the station are exceptionally favorable, and 

what appears to be an absolutely permanent rating curve has been 

established. The datum of the gage has not been changed and the 

data are considered absolutely trustworthy.

The following measurement was made November 24, 1908:

Width, 263 feet; area, 542 square feet; gage height, 1.87 feet; discharge, 427 secondfeet.

Daily gage height, in feet, of John Day River at McDonald, Oreg., for 1907 and 1908.

SOUTH FORK OF JOHN DAY RIVER AT DAYVILLE, OREG.

This station, which was established November 21, 1908, is located 

one-half 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 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.

The following measurement was made November 22, 1908:

Width, 71 feet; area, 51 square feet; gage height, 0.46 foot; discharge, 41 second-feet.

DESCHUTES RIVER DRAINAGE BASIN. 

DESCRIPTION.

Deschutes River has its source in a number of mountain lakes at 

the summit of the Cascades just over the mountains from the headwaters of Willamette River, and its course is northward to the 

Columbia, 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 the Crooked River drain the eastern slope of 

the Cascades and contribute the larger portion of the stream flow. 

The entire drainage area of the system is 9,180 square miles, distributed as follows:

DESCHUTES RIVER DRAINAGE BASIN. 305

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 has 

the effect of a huge sponge. Deschutes River has perhaps the most 

remarkably 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 only six times the minimum. Ocular 

evidence of this uniformity of flow is presented by the low grassgrown banks between which the river flows for its entire course.

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 only timbered portion of this drainage basin is found on the 

eastern slope of the Cascades, and constitutes about 15 per cent of 

the total area. The divide between Crooked River and the John 

Day basin is sparsely timbered. The uniform flow of this stream 

can not be attributed to forestatiori. Indeed the entire timber supply could be removed without in the least affecting the flow of the 

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. 

Twenty-five miles farther east, 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 conditions do 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 and result from 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 

mouth, a distance of 140 miles, is capable of furnishing a million 

horsepower, and by including such tributaries as White and Metolius 

rivers and the West Fork, this figure may probably be raised to a 

million and a half. Power plants need fear neither shortage of water 

during the summer months nor damage from flood. During the lowwater period, throughout the lower 130 miles of the river's course, it 

flows in a narrow canyon with an average fall of 20 feet to the mile, 

and conditions are such that a succession of dams could be built 

almost throughout its entire length.

306 SURFACE WATER SUPPLY, 1907-8.

The following gaging stations have been maintained in this drainage 

basin:

Deschutes River at Alien's ranch, near Lava (Little River) (1905 and 1908).

Deschutes River at West's ranch near Lava (1906 to 1908).

Deschutes River at Bend (1904 to 1908).

Deschutes River near Moro (1897, 1898, and 1899).

Deschutes River near Biggs (1906 to 1908).

East Fork of Deschutes River at Crescent (1904 to 1908).

West Fork of Deschutes River (Big River) near Lava (1905 to 1907).

Tumalo Creek near Laidlaw and Bend (1906, 1907, and 1908).

Lewis Creek near Laidlaw, Oreg. (1908).

Squaw Creek near Sisters (1907 and 1908).

Crooked River near Post (1908).

Crooked River near Prineville (1908).

Ochoco Creek near Prineville (1908).

Metolius River near Sisters (1908).

DESCHUTES RIVER AT ALLEYS RANCH, NEAR LAVA, OREG.

This station, which was established February 17, 1905, is located 

one-half mile above the mouth of the West Fork at C. B. Alien's 

ranch, 1 mile north of Lava. The stream at this point is locally 

known as Little River. The data obtained here are particularly 

valuable in connection with irrigation development and in a general 

study of the run-off factors of this very interesting area.

The datum of the gage has not been changed since the station was 

established, but the records are not as accurate as could be wished. 

During the summer months a very troublesome growth of weeds 

appears in the river in the vicinity of the station, and as the season 

advances these weeds greatly retard the water and create backwater conditions at the gage. Discharges for 1908 have therefore 

been obtained by an indirect method, similar to that used for shifting 

channels. Where a sufficient number of measurements are made 

this method will give fairly reliable results, but as only a few have 

been made at this station, the results are liable to error. Prior to 

1908 a curve averaging all the measurements was made.

DESCHUTES RIVER AT WEST'S RANCH, NEAR LAVA, OREG.

This station was established June 20, 1906, at a private bridge on 

West's ranch, 18 miles above Bend. It is just below the mouth of 

Spring River and about 1^ miles below the mouth of West Fork.

This station affords exceptionally good 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 

and Power Company. The complete reclamation of all land segregated under this law will bring the total to 225,000 acres under 

irrigation.

The river at this point never freezes, as the stream is entirely 

spring-fed, and although the stream is used for logging, the channel 

is deep and the current swift and gaging operations are not affected. 

The gage datum has not been changed since the station was installed, 

and the records are continuous.

312 SURFACE WATER SUPPLY, 1907-8.

DESCHUTES RIVER AT BEND, OREG.

This station was established at Sizemore's bridge December 22, 

1904. Although data were published for 1905 and 1906, they are 

not at all reliable. The conditions at the station are not favorable 

for accurate results, as the channel 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. On 

March 30, 1907, gage records were suspended at this point and on 

April 23, 1907, they were begun at Staat's bridge in the town of 

Bend. The conditions at this bridge, however, are no better than 

they were at the former location, and discharge measurements are 

inconsistent. The records of gage heights, which are furnished 

without cost to the U. S. Geolog'ical Survey by Mr. C. A. Stanburrough, engineer of the city pumping plant, are published as being of 

general interest in the study of the river system. The discharge at 

this point is practically the same as at West's ranch.

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 Taylor's 

ranch, 1J miles above the mouth of the river. 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 

the conditions at the earlier station are not nearly so favorable for 

accurate results as are those in the present location.

316 SURFACE WATER SUPPLY, 1907-8.

EAST FORK OF DESCHUTES RIVER AT CRESCENT,0 OREG.

This station, which was established December 25, 1904, and 

abandoned March 31, 1908, was located at Crescent, in the SW. ^ 

sec. 30, T. 24 S., R. 9 E.

The data obtained here are particularly valuable in connection 

with irrigation development. A large project involving the irrigation of Walker basin is proposed, the water supply for which will be 

obtained from this stream. The conditions at the station are not 

favorable for good results and those obtained are liable to considerable 

error.

WEST FORK OF DESCHUTES RIVER NEAR LAVA, OREG.

A station was established February 26, 1905, on the stream locally 

known as Big River, 1J miles west of Lava post-office and about the 

same distance above the mouth of the stream, in the NE. J sec. 24, 

T. 20 S., R. 10 E. As it was impossible to obtain continuous observations of gage height, the station was abandoned March 31, 1907.

The station furnishes data of considerable economic value, as the 

waters of the stream will be largely used for irrigation and some 

exceptional storage sites are found on its headwaters. The flow of 

the West Fork can approximately be estimated by deducting the 

flow of the Deschutes (Little River) at Lava and about 300 secondfeet for Spring River, from the flow obtained on Deschutes River at 

West's ranch. (See description of Deschutes River at West's ranch.)

TUMALO CREEK NEAR LAIDLAW AND BEND, OREG.

This station, which was established May 15, 1906, has been maintained at two different points on the stream. The regular Tumalo 

station was originally located one-half mile above the head-gate of 

the Columbia Southern canal in sec. 2, T. 18 S., R. 10 E. At this 

point records were obtained during the irrigating season only, observations being taken by the patrolman on the Columbia Southern canal, 

who lived at the head-gate. During the winter months, however, no 

patrolman was kept at this point, and records were obtained at a bridge 

on the Bend-Sisters road about 6 miles downstream from the regular Tumalo station. At the lower point approximate results have 

been obtained during the winter months, although the conditions do 

not favor accuracy. The gage datum has been changed, as the bridge 

was removed some time during the winter of 1907-8, and the gage was 

moved with it without making record of the date of change.

The records from the regular station at Tumalo during the irrigating season are fairly reliable, as the conditions are favorable for good 

results, and observations were carefully and conscientiously kept. 

The records of gage height are furnished without cost to the Survey 

by the Columbia Southern Irrigating Company. During the irrigating season of 1906-7 the station was located between the head-gate 

of the Columbia Southern canal and the head-gate of the Wimer ditch. 

The natural flow at this point is obtained by adding the diversion of 

Wimer canal to the flow in the stream. On April 1, 1908, the station was moved to a point 1J miles above the intake of the Columbia 

Southern canal and about 300 feet above the intake of Wimer canal. 

(See the descriptions of stations on these canals.)

The data obtained on Tumalo Creek are valuable principally in 

connection with irrigation development. The Columbia Southern 

Irrigating Company selected about 27,000 acres of land for reclamation under the provisions of the Carey Act without having adequate 

information as to the water supply. The canal was hurriedly con-

structed and land was sold to the settlers. It was afterward found 

that the quantity of water was not sufficient without storage to 

supply more than one-third of the segregation. This has entailed a 

great amount of litigation and has been a great source of trouble 

between the State, the company, and the settlers.

NOTE. Discharges for January 1 to April 18,1907; November 1, 1907 to March 31,1908, and November 1 

to December 31 are for the station near Bend. For April 19 to October 31, 1907, they are the sums of the 

discharges at the Laidlaw station and of the Wimer canal; for April to October, 1908, they are for the Laidlaw 

station above the Wimer canal. The values for March, April, and November, and possibly for the winter months, may not correctly represent the total flow of the creek, as there may have been some water 

diverted past the lower station in both the Wimer and Columbia Southern canals. The minima of both 

1907 and 1908 are liable to error on this account, but the effect on the yearly means should not be very

LEWIS CREEK NEAR LAIDLAW, OREG.

This station was established April 2, 1908, at the mouth of the 

creek, which has its source in a small lake and empties into Tumalo 

Creek 2 miles above the intake of the Columbia Southern canal.

The data will be valuable in the study of possible storage development in the basin of Tumalo Creek.

SQUAW CREEK NEAR SISTERS, OREG.

This station, which was established June 15, 1906, is located above 

all present ditches with the exception of McAllister ditch, which 

was not completed at the time the station was established. There 

is a waste-way from McAllister ditch just below the station, and 

the flow in the canal should be added to that in the creek to determine the natural flow at this point. (See list of miscellaneous measurements in the Deschutes drainage basin for gagings of McAllisters 

ditch.)

The waters of Squaw Creek are extensively used for irrigation in 

small ditches, and segregation of large areas of land have been made 

for reclamation under the provisions of the Carey Act to be irrigated 

from this creek.

The data at this station are not very reliable. A short distance 

below the station is a diversion dam, consisting of logs, brush, stone, 

etc., which either goes out entirely or is altered during freshets, 

so that the relation between gage height and discharge at the station 

is not stable. The gage washed out on January 12, 1909. The 

stream usually freezes during a portion of the winter and during 

such period records are unreliable.

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, in the NE J 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. Elliott's ditch diverts water from the 

left bank of Ochoco Creek about 1,000 feet above the gaging station. 

A station is also maintained on the ditch in order to determine the 

natural flow of the creek at this point.

The following measurement was made on Ochoco Creek, December 

27, 1908:

Width, 12 feet; area, 7 square feet; gage height, 0.10 feet; discharge, 5.5 secondfeet.

NOTE. Water was standing in pools November 4 to 8; creek frozen over December 20, and partly frozen 

December 21 to 30.

The following measurement was made on Elliott ditch, November 

3, 1908:

Width, 6.3 feet, area of section 3.5 square feet, gage height 2.32 feet, discharge 2.9 

second-feet.

From November 4 to 8, gage height 1.3 feet; November 9 to December 31 the ditch 

was dry.

METOLIUS RIVER NEAR SISTERS, OREG.

This station was established October 31, 1908, at Riggs's ranch, 7 

miles above the mouth of the stream and 26 miles northwest of 

Sisters, in sec. 28, T. 11 S., R. 11 E.

The results obtained here will be particularly valuable for use in 

connection with water-power 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, no 

doubt because of the very porous nature of the soil composing the area. 

The headwaters are quite heavily forested.

The following measurement was made October 22, 1908:

Width, 102 feet; area, 326 square feet; gage height, 0.60 foot; discharge, 1,490 secondfeet.

CANALS AND DITCHES IN DESCHUTES RIVER BASIN. 

CENTRAL OREGON AND PILOT BUTTE CANALS NEAR BEND, OREG.

These 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 and 

Power Company, 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, 

in which the State of Oregon is deeply interested.

The station on the Central Oregon canal was established March 11, 

1905; measurements are made from flumes. The maximum amount 

diverted into this canal since its construction was 248 second-feet, 

August 10 to 13, 1908.

The station on Pilot Butte canal was established March 6, 1905, 

one-half mile below the waste-way 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 maximum amount diverted since the construction 

of the canal is 284 second-feet on August 9 to 12, 1908.

WIMER CANAL NEAR LAIDLAW, OREG.

This canal diverts water from Tumalo Creek about three-fourths 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 

irrigating 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 this year show the net amount diverted for irrigation. 

To obtain the natural flow of the stream at this point for the years
DESCHUTES EIVER DRAINAGE BASIN. 335

1906 and 1907, the quantity diverted should be added to the flow in 

the creek. During 1908 the station on the creek was moved to a 

point above the intake of the Wimer canal, and the records there 

obtained represent the natural flow of the stream. The records of 

gage height are furnished without cost to the United States Geological 

Survey by the Columbia Southern Irrigating Company.

COLUMBIA SOUTHERN CANAL NEAR LAIDLAW, OREG.

This station, which was established May 15, 1906, is located in 

a flume 200 yards below the head-gate of the canal. The canal was 

constructed by the Columbia Southern Irrigation Company 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 U. S. Geological 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.

HOOD RIVER DRAINAGE BASIN. 

DESCRIPTION.

Hood River drains the northern slopes of Mount Hood. It is 

formed by the junction of the East and West forks, which drain 

opposite sides of the mountain, and flows northeastward into Columbia River at Hood River. The waters of the stream are used for 

both water power and irrigation, and, being supplied from the glaciers 

on the mountain, the flow is well maintained through the summer 

months. The drainage area is heavily forested although part of the 

area was burned many years ago. The mean annual precipitation 

at Hood River is 36 inches. The valley of the stream is noted for 

its production of apples, berries, and other fruit. The following 

gaging stations have been maintained:

Hood River at Tucker's Bridge (1897 to 1899). 

Hood River at Winans (1905 to 1907).

HOOD RIVER AT WINANS, OREG.

This station was established November 17, 1905, and abandoned 

March 31, 1907, because it was impossible to obtain continuous gageheight records. It was located 300 feet below the junction of the 

East and West forks at Winans, 10^ miles above Hood River, Oreg.

The data obtained at this station are of considerable scientific 

interest and economic value. The waters of the stream are largely
340 SURFACE WATER SUPPLY, 1907-8.

used for both, irrigation and water power. The stream is supplied by 

glaciers and its drainage area is very heavily forested. The flow is 

well maintained throughout the summer months. The gage datum 

was not changed. During the maintenance of the station the conditions were not favorable for reliable results. High waters caused 

changes in the channel and rerating was necessary after each change. 

No measurements were made during 1907.

SUKFACE WATER SUPPLY, 1907-8. 341 

SANDY RIVER DRAINAGE BASIN. 

DESCRIPTION.

Sandy River has its source in the glaciers of Mount Hood and flows 

northwestward, uniting with Columbia River at Troutdale. It 

drains the eastern slope of the Cascade Mountains at the very northern 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. 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 rain during the nine months from September to May. 

The value of the waters of this stream lie in their availability for 

municipal water supplies and in the 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.

Estimates of maximum and minimum values can not be made, as the 

records do not cover a sufficiently long period. Judging from records 

kept in adjacent* areas, the maximum discharge during recent years 

probably occurred in the winter of 1907 and the minimum in September or October of 1905. 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. 

Such a condition, however, would not occur except after an exceptionally dry fall. The waters are milky during the summer months.

The following gaging stations are maintained in this river basin:

Sandy River at Salmon post-office (1908).

Bull Run River near Bull Run (1907 and 1908).
342 SURFACE WATER SUPPLY, 1907-8.

SANDY KIVER AT SALMON, OREG.

This station was established December 12, 1907, at a highway 

bridge 1 mile below Salmon post-office. It is 1 mile below the mouth 

of Salmon River. This station furnishes data of value chiefly in connection with water-power development.

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, and on this account the final 

results are not as accurate as could be desired.

BULL RUN RIVER NEAR BULL RUN, 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. It is situated about 1^ miles above the intake of 

a 30-mile pipe line that supplies the city of Portland with water. 

The gage is located just above a small wing dam construction 

which diverts water into the pipe line. The measurements are made 

from a cable about 1| miles above this point. This wing dam is 

merely a rock-and-brush affair which is built during the low-water 

period. It washes out at the first freshet in the fall. Its effect has 

been detrimental to accurate results on account of backwater effect 

at the gage.

The facilities are good for accurate gagings. The drainage area 

of this stream is completely and densely forested and the water is 

exceptionally clear and pure.

WILLAMETTE RIVER DRAINAGE BASIN. 

DESCRIPTION.

Willamette River drains a shallow trough-shaped area, extending 

north and south between the Coast and Cascade ranges in Oregon. 

The area is roughly rectangular, approximately 230 miles in 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 the Willamette are Santiam, Mollala, 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:

WILLAMETTE RIVER DRAINAGE BASIN. 347

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 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, still exists, as the water-producing portions of the area 

have not been disturbed.

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 Calapooia 

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 in 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 agriculture lands 

show an increase from 50 to 500 per cent in production over the nonirrigated lands.

No portion of this area has ever 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 this river system, as it would probably render 

the river navigable from Eugene to its mouth during all portions of
348 SUEFACE WATER SUPPLY, 1907-8.

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.* If storage facilities for impounding 850,000 acre-feet per annum could be found, 

the navigability of the river from Eugene to the mouth would be 

assured, and the entire cost of construction would be more than 

returned from benefits which would accrue in increased water-power 

facilities at Oregon City alone.

The highest known flood in 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. 77 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.

The following gaging stations have been maintained in this river 

basin:

Middle Fork of Willamette River at Jasper (1905 to 1908).

Willamette River at Albany (1895 to 1908).

Coast Fork of Willamette River at Goshen (1905 to 1908).

McKenzie River near Springfield (1905 to 1908).

North Fork of Santiam River at Detroit (1907 to 1908).

North Fork of Santiam River at Mehama (1905 to 1907).

Santiam River at Jefferson (1905, 1906, and 1908).

Marion Fork of Santiam River at Marion Lake, near Detroit (1907).

Puzzle Creek near Detroit (1907).

Permelia Creek near Detroit (1907).

Whitewater Creek near Detroit (1907).

South Fork of Santiam River at Waterloo (1905 to 1907).

Luckiamute River near Suver (1905 to 1908).

South Fork of Yamhill River at Sheridan (1906 to 1908).

Yamhill River at Lafayette (1908).

Molalla River near Molalla (1905 to 1908).

Clackamas River at Barton and Estacada (1905 to 1908).

MIDDLE FORK OF WILLAMETTE RIVER AT JASPER, OREG.

This station was established September 16, 1905, and has been 

maintained continuously since that date, although owing to loss of 

gaging equipment during the flood of February, 1907, no gagings 

were made during that year. The equipment was replaced October 

13, 1908, and subsequent measurements have developed a curve that 

is applicable to the gage heights obtained during the interval. The 

station is located at the ferry near Jasper post-office, 2 miles above 

Natron and 3 miles below the mouth of Fall Creek.
WILLAMETTE RIVER DRAINAGE BASIN. 349

The waters of this stream are particularly valuable for waterpower, and will no doubt 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. 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.

352 SURFACE WATER SUPPLY, 1901-8.

WILLAMETTE RIVER AT ALBANY, OREG.

This station, which was established July 21, 1905, is located at the 

Corvallis and Eastern Railroad bridge within the city limits of 

Albany, just below the mouth of Calapooia River and 7 miles above 

the mouth of Santiam River.

It was established in connection with the general study of the runoff of Willamette River and its tributaries, to develop a rating curve 

for gage heights of long standing which had been obtained by the 

United States Weather Bureau. The data will be particularly valuable for the determination of run-off values from forested areas and 

will be used in the proper design of river improvements for navigation 

purposes and for development of water power and irrigation. Readings have been obtained at the railroad bridge since the station was 

established, but it has been found that the Weather Bureau gage is 

located at a more permanent section and they have therefore been 

used in preference to those at the Survey gage. The measurements 

at medium and low stages have been plotted as coordinates with the 

Weather Bureau observer's reading for the day.

The gage heights at the Weather Bureau gage from 1879 to 1906 

have been published in " Daily river stages of the principal rivers of 

the United States," as follows:

1878-1888, Part III, pp. 46-56. 

1892, Part IV, p. 435. 

1893-1895, Part V, pp. 36-38. 

1896-1899, Part VI, pp. 116-117. 

1900-1904, Part VII, pp. 202-204. 

1905-6, Part VIII, p. 73.

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 and 4 miles above the mouth of Coast 

Fork. 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 times, but they have 

been replaced at the same datum and no material inaccuracy in the 

records has been caused on this account.

WILLAMETTE KIVER DRAINAGE BASIN. 361

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 has recently been replaced by a 

highway bridge 3 miles below Waterville, 4 miles above Thurston, 

and 3 miles above the 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 

both irrigation and water power. The station also furnishes data 

for determining run-off factors from heavily forested areas with 

high rainfall.

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. The measurements taken during high water are not very 

reliable. The water is too swift to make soundings possible, and 

depths are necessarily estimated from previous measurements at a 

lower stage, but as the gage is located about 200 feet above the 

point of measurement, the height of water surface at the cable can 

not be determined accurately. Since the establishment of the 

station a highway bridge has been built between the gage and the 

cable, and whatever relation may have existed between the height 

of the water surface at the gage and at the cable has been disturbed 

by the piers of this bridge, which have caused bars to form below 

them. Individual measurements of low and medium stages can be 

made with accuracy and are reliable.

364 SURFACE WATER SUPPLY, 1907-8.

NORTH FORK OF SANTIAM RIVER AT DETROIT, OREG.

This station was established January 24, 1907, by J. G. Kelley, of 

Portland, who has cooperated with the U. S. Geological Survey in 

its maintenance. The station is located at a footbridge 1 mile above 

Detroit, about 1J miles above the mouth of Britenbush 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 

(PI. VIII).

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.

NORTH FORK OF SANTIAM RIVER AT MEHAMA, OREG.

This station, which was established July 5, 1905, was discontinued 

March 31, 1907. It was located just below the highway bridge at 

Mehama, about 1J miles north of Lyons and 12 miles below the 

junction of Little North Fork and North Fork.

This stream is subject to excessive floods. During one of these 

the gaging equipment was destroyed and the station was abandoned 

in favor of the station at Detroit.

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 the highway bridge at Jefferson, 2J 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, falling very low in the 

summer time and being subject to excessive and violent floods. The 

North Fork, on the other hand, maintains a well-established flow 

during the low-water season, and although the actual flood discharge 

is probably as high as that obtained from the South Fork, the value 

per square mile is considerably less.
368 SUEPACE WATEE SUPPLY, 1907-8.

The records obtained from the date of establishment to July 1, 1906, 

are not reliable. The gage was located on a pier of the bridge, and it 

was impossible to obtain even approximate heights during flood 

time. Since its reestablishment on October 15, however, the gage 

installed by the Jefferson Mill Company is used. It is located at the 

mill just above the bridge, where accurate heights can be obtained.

The following measurement was made October 15, 1908:

Width, 433 feet; area, 3,880 square feet; gage height, 3.75 feet; discharge, 9,550 

second-feet.

MARION FORK OF SANTIAM RIVER AT MARION LAKE, NEAR DETROIT,

OREG.

This station was established February 23, 1907, by J. G. Kelley, of 

Portland, through whose courtesy the records are furnished. It is 

located about 200 feet below the outlet of Marion Lake, 30 miles from 

Detroit, from which town it is reached by trail. The gage heights are 

obtained by measuring down from a reference point. The results 

will be of value in connection with the development of water powers 

on this stream. The individual measurements are accurate, but on 

account of the isolation of the station it has been impossible to 

obtain a sufficient number of measurements and heights to insure 

reliable estimates of flow.

PUZZLE CREEK NEAR DETROIT, OREG.

This station was established February 23, 1907, by J. G. Kelley, of 

Portland, who furnishes the records. The gage heights are obtained 

by measuring down from a reference point which has an assumed 

elevation of 10.0 feet. The stream has a prodigious fall, and the 

results will be of considerable value for the general study of waterpower development on the North Fork of the Santiam.

The station is located about 50 feet above the mouth of the stream, 

in the only point where the water is quiet enough to admit of even 

an approximate gaging being made. The station is isolated, and

WHITEWATER CREEK NEAR DETROIT, OREG.

This station was established February 23, 1907, and has been 

maintained by J. G. Kelley, of Portland, by whom the records are 

supplied. It is located about one-quarter mile above the mouth 

of the stream, in the NW. i sec. 21, T. 10 S. 7 R. 7 E., and is reached 

by trail from Detroit.

The data from this station are of value in the general study of 

the water-power possibilities of the North Fork of Santiam River. 

Gage readings are obtained by measuring down from a reference 

point which has an assumed elevation of 10.0 feet. Sufficient measurements have not been made to develop a reliable rating curve, 

and the chief dependence for data will be the measurements that 

have been obtained. No gage heights were obtained during 1908.

SOUTH FORK OF SANTIAM RIVER AT WATERLOO, OREG.

This station was established July 28, 1905, and was discontinued 

March 31, 1907. It was located one-half mile below the highway 

bridge at Waterloo, about 4 miles above the mouth of Hamilton 

Creek, and 3 miles above the dam by means of which water is diverted 

into a power canal for use in the town of Albany. The floods of 

November, 1906, destroyed the gaging equipment, and although 

the records are of considerable value the available funds would not 

permit of its reestablishment.

LUCKIAMUTE RIVER NEAR STIVER, 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 south of Monmouth and 

3 miles below the junction of the North and South forks.
374 SURFACE WATER SUPPLY, 1907-8.

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.

a Discharge interpolated September 3 to 11.

SOUTH FORK OF YAMHILL RIVER AT SHERIDAN, OREG.

This station was established April 25, 1906. It is located at the 

highway bridge in Sheridan, 2 miles below the mouth of Mill Creek.

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.

No change in gage datum has occurred since the station was established, and 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.

YAMHILL RIVER AT I.A FAYETTE, OREG.

This station, which 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, is located at the 

county highway bridge at La Fayette, Oreg., three-fourths of a 

mile above the locks and about 1^ miles below the junction of the 

North and South forks.

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.

MOLALLA RIVER NEAR MOLALLA, OREG.

This station, which was established November 1, 1905, 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.

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.

NOTE. Low-water discharge below 165 second-feet for July to November, 1907, and July to September 

1908, estimated and intercompared with the discharge of Clackamas and North Fork of Santiam rivers. 

The mean values given are subject to large errors and are merely given for the purpose of showing in a 

rough way the relatively low flow at this station as compared with other adjacent streams at extreme low 

Stages.
WILLAMETTE RIVER DRAINAGE BASIN.

CLACKAMAS RIVER AT ESTACADA, OREG.

383

' This station was established April 6, 1908, and replaces the station 

formerly maintained at Barton. It is located on the Oregon Water 

Power Company's park at Estacada, about If miles downstream 

from the Portland Railway Light and Power Company's hydroelectric plant at Cazadero. The river at this point flows in a deep 

canyon, and it was impossible to find a site which should combine 

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, and a rating curve 

has been developed for each. 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 and need not be given consideration.

The non-uniform 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, nearly disappears 

at medium stage, and is eliminated at high water.

CLACKAMAS RIVER NEAR BARTON, OREG.

This station was established October 2, 1905, and was maintained 

until superseded by the station at Estacada, established April 6, 1908. 

It is located on the farm of H. Breithaupt, 3 miles west of Barton and 

1.5 miles below the mouth of Deep Creek, in sec. 20, T. 2 S., R. 3 E.

This stream is particularly valuable for its water power, and in this 

connection the records of flow have been invaluable. They are also 

of great scientific interest, as they furnish data concerning the run-off 

from heavily forested areas, and will be extensively used in the general 

study of the water supply of the Willamette River system.

The river never freezes at this point, and the records are believed 

to be fairly reliable. The river, however, is subject to heavy floods, 

which have caused damage to gages and gaging equipment, so that 

4uring the year 1907 no measurements were obtained, although the 

gage-height records are complete. Gage-height records were continued until the close of the year 1908 in order to obtain a comparison 

between the gages at Estacada and Barton. One measurement was 

made during the summer of 1908 to determine the applicability of the 

rating of 1906 to later gage heights.

The following measurement was made September 26, 1908, from a 

boat 150 feet above the former cable section:

Width, 137 feet; area, 311 square feet; gage height, 2.61 feet: discharge, 816 secondfeet.

SURFACE WATER SUPPLY, 1907-8. 389

PTJGET SOUND DRAINAGE BASIN.

DESCRIPTION.

The drainage of the western slope of the Cascade Mountains in 

Washington is to Puget Sound. The most important streams are Nisqually River, which drains the southern portion of Mount Rainier; Puyallup River, which drains 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; Stillagaumish 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 enormous quantities of water power (PL IX), 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 niches 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 Marble Mount 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, i% rarely high enough to do a great amount of damage, as the
390 - SURFACE WATER SUPPLY, 1907-8. .

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 highest flood from this cause occurred November 14 

to 17, 1906.

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.

The following gaging stations have been maintained in this basin:

White River near Buckley (1899 to 1902).

Cedar River at Ravensdale (1902 to 1908).

Cedar River at Cedar Lake (1902 and 1903).

Cedar River near Seattle (1895 to 1898).

Snoqualmie River at Snoqualmie Falls (1902 to 1906).

Stillaguamish River near Robe (1902 and 1903).

South Fork of Skykomish River at Index (1902 to 1905).

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 Ravensdale.

The data obtained at this station are of great value, as they are 

continuous and reliable and constitute practically the only stream 

flow 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 (1) is 120 feet. It is steel shod, of triangular 

section. The upstream slope forms an angle of 30 degrees with the 

horizontal and the downstream slope an angle of 60 degrees. For 

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. (For a description of 

the measurement of the amount diverted see Trans. Am. Soc. Civil 

Eng., vol. 49, p. 112.) The datum of the gage is the elevation of 

the crest of the dam 436 feet above sea level, and has not been altered 

since it was established. The results are reasonably accurate.

SURFACE WATEE SUPPLY, 1907-8. 393 

SUMMARY OF MEAN DISCHARGE PER SQUARE MILE.

The following summary of mean discharge per square mile is given 

to allow ready comparison of relative rates of run-off from different 

areas in the north Pacific coast drainages. It shows in a general 

way the seasonal distribution of run-off, and the effect of snow, 

ground, surface, and artificial storage. The most important fact 

worth noting is the almost entire lack of uniformity or agreement 

between any two stations. This indicates that the discharge of each 

stream is a law unto itself, and that all projects dependent on stream 

flow, if they are to be developed along the safest and most economical 

lines, must be based on records of stream flow collected with great 

care over a long series of years as near the location of the project under consideration as possible.
