INTRODUCTION.

AUTHORITY FOB 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 80, 1895, 

by appropriations in successive sundry civil bills passed by Congress 

under the following item:

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

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

The various appropriations that have been made for this purpose 

are as follows:

Annual appropriations for the fiscal year ending June 30 

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

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

SCOPE OF INVESTIGATIONS.

These investigations of stream flow are not complete nor do they 

include all the river systems or parts thereof that might purposefully 

be studied. The scope of the work is limited by the appropriations 

available. The field covered is the widest and the character of the 

work is believed to be the best possible under the controlling conditions. The work would undoubtedly have greater scientific importance and ultimately be of more practical value if the money now 

expended for wide areas were concentrated on a few small drainage 

basins; but such a course is impossible because general appropriations made by Congress are applicable to all parts of the country. 

Each part demands its proportionate share of the benefits. ,

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

period of years long enough to determine within reasonable limits the 

entire range of flow from the absolute maximum to the absolute 

minimum. The length of such a period manifestly differs for different streams. Experience has shown that the records for some 

streams should cover from five to ten years, and for other streams 

twenty years or even more, the limit being determined by the relative 

importance of the stream and the interdependence of the results with 

other long-time records on adjacent streams.

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

degree of precision possible with a rational expenditure of time and a 

judicious expenditure of a small amount of money. In all engineering work there is a point beyond which refinement is needless and 

wasteful, and this statement applies with especial force to streamflow measurements. It is confidently believed that the stream-flow 

data presented in the publications of the Survey are in general sufficiently accurate for all practical purposes. Many of the records are, 

however, of insufficient length, owing to the unforeseen reduction of 

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

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

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

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

has been investigated. During 1909 regular gaging stations were 

maintained by the Survey and cooperating organizations at about 

850 points in the United States, and many miscellaneous measurements were made at other points. Data were also obtained in regard 

to precipitation, evaporation, storage reservoirs, river profiles, and 

water power in many sections of the country and will be made available in the regular surface water-supply papers and in special papers 

from time to time.
THE GREAT BASIN. 9 

PURPOSES OF THE WORK.

The results contained in this volume are requisite to meet the 

immediate demands of many public interests, including navigation, 

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

land drainage, and flood prevention.

Navigation. The Federal Government has expended more than 

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

It is obvious that the determination of stream flow is necessary to the 

intelligent solution of the many problems involved.

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

federal irrigation systems, and this amount is far exceeded by the, 

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

of any irrigation system depends absolutely on the amount of water 

available. Therefore investigations of stream flow in that portion of 

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

lands, but constitute an insurance of federal and private investments.

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

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

interest than the branches already named, it nevertheless has so 

broad a significance with respect to the general welfare that the 

Federal Government is ultimately and intimately concerned.

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

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

and the cost of steam power is increasing accordingly. Industrial 

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

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

affords the only avenue now open. When the electric transmission 

of power was accomplished the relation of our water powers to 

national economy changed entirely. Before the day of electric 

transmission, water power was important only at the locality at 

which it was generated, but it has now become a public utility in 

which the individual citizen is vitally interested. Inasmuch as the 

amount of water power that may be made available depends on the 

flow of rivers, the investigation of flow becomes a prerequisite in the 

judicious management of this source of energy.

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

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

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

When this land is drained it becomes exceedingly productive and its 

value increases many fold. Such reclamation would add to the 

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

consideration in connection with drainage projects. If by the drainage of a large area into any particular channel that channel becomes

so gorged with water which it had not hitherto been called upon to 

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

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

drainage improvement.

Flood prevention. The damage from floods in the United States 

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

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

the property of great regions should be reduced in the orderly progress 

of government. It goes without saying that any consideration of 

flood prevention must be based on a thorough knowledge of stream 

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

along the great lowland rivers.

PUBLICATIONS.

The data on stream flow collected by the United States Geological 

Survey since its inception have appeared in the annual reports, 

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

evolution and to changes in governmental requirements, the character 

of the work and the territory covered by these different publications 

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 1909. 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 1909. 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.

THE GREAT BASIN. 13

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

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

of drainage area, local changes in name and lake surface being disregarded. After all stations from the source to the mouth of the 

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

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

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

being given before taking up the next one below.

The exceptions to this rule occur in the records for Mississippi 

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

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

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

forth over the lake surface.

DEFINITION OF TERMS.

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

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

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

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

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

defined as 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 wider 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.

THE GREAT BASIN. 15 

EXPLANATION OF TABLES.

For each drainage basin there is given a brief description of general 

conditions covering such features as area, source, tributaries, topography, geology, conditions of forestation, rainfall, ice conditions, 

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

importance or interest.

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

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

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

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

For stations located at weirs or dams the gage-height table is omitted.

In addition to statements regarding the location and' installation 

of current-meter stations the descriptions give information in regard 

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

gage height to discharge, covering such points as ice, logging, shifting 

conditions of flow, and backwater; also information regarding diversions which decrease the total flow at the measuring section. Statements are also made regarding the accuracy and 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.

The discharge measurements and gage heights are the base data 

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

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

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

recorded during the period for which it is applicable. It is not 

published in this report but can be determined from the daily gage 

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

First plot the discharge measurements for the current and earlier 

years on cross-section paper with gage heights in feet as ordinates
16 SURFACE WATER SUPPLY, 1909 PART X.

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

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

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

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

curve used and will lie among the plotted discharge measurements. 

After drawing the rating curve, a table can be developed by scaling 

off the discharge in second-feet for each tenth foot of gage height. 

These values should be so adjusted that the first differences shall 

always be increasing or constant, except for known backwater 

conditions.

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

corresponding to the observed gage heights as determined from the 

rating tables.

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 13, are based.

FIELD METHODS OP MEASURING STREAM PLOW.

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^/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 dis* 

charge 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 GREAT BASIN. 17

the general conditions. It is seldom used by the United States 

Geological Survey.0

Weir method. Relatively few stations are maintained at weirs or 

dams by the United States Geological Survey. Standard types of 

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

accurate coefficients have been experimentally obtained give very 

accurate records of discharge if properly maintained. At practically 

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

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

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

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

backwater at high stages, uncertainty regarding coefficient, 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.6

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 of the discharge curves 

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

In determining the daily flow different office methods are necessary 

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

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

the same.

Great care is taken in the selection and equipment of gaging 

stations for determining discharge by velocity measurements, in 

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

a Full information regarding this method is given in the various text-books on hydraulics.

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

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

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

exhausted. It can, however, be consulted at most of the larger libraries of the country or it can be obtained 

from the superintendent of documents, Washington, D. C., at a cost of 20 cents.

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 esentially 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 PL I, A.) These points are spaced equally for 

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

and are spaced unequally for other parts according to the discretion 

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

spaced farther apart than 5 per cent of the distance between 

piers, nor farther apart than the approximate mean depth of the 

section at the time of measurement.

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.0

Depths for the determination of the area are usually obtained by 

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

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

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

section.

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

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

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

this method is limited to special conditions where it is impracticable 

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

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

high degree of accuracy is not necessary. Tube floats are very satisfactory for ase 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.0

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.6

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

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

left the same type of meter is shown equipped for wading measurements, to record by the acoustic method; on the right the meter 

is shown equipped to record electrically. (See PL I, B.} Briefly, 

the meter consists of six cups attached to a vertical shaft which 

revolves on a conical hardened steel point when immersed in moving water. The revolutions are indicated electrically. The rating, 

or relation between the velocity of moving water and the revolutions 

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

water for a given distance at different speeds and noting the number 

of revolutions for each run. From these data a rating table is prepared which gives the velocity per second of moving water for any

text-books on stream flow.

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 PL I, A.) On the 

assumption that the vertical velocity curve is a common parabola 

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

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

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

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

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

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

practice of the United States Geological Survey.

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

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

for which the coefficient for reducing to mean velocity has been 

determined or must be assumed.

Extensive experiments by means of vertical velocity curves show 

that the thread of mean velocity generally occurs between 0.5 and 

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

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

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

large number of vertical velocity curve measurements, taken on 

many streams and under varying conditions, show that the average 

coefficient for reducing the velocity obtained at 0.6 depth to mean

SMALL PRICE CURRENT METERS.
THE GREAT BASIN. 21

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 

th"e 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.0

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

o For information in regard to flow under ice cover see Water-Supply Paper U. S. Geol. Survey No. 187.
22 SURFACE WATEK SUPPLY, 1909 PAET X.

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. 17.) 

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 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 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 figure 1 and 

stations of the north Atlantic coast drainage basins.

Class 2 is confined mainly to stations on rough, mountainous 

streams with steep slopes. The beds of such streams are as a rule 

comparatively permanent during low and medium stages and when 

the flow is sufficiently well defined by an adequate number of discharge 

measurements before and after each flood the stations of this class
THE GKEAT BASIN. 23

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 examples of 

stations of this type see stations of the upper Missouri River basin.

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

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

funds at the disposal of the Survey this is manifestly impossible, nor 

is it'necessary for the uses to which discharge data are applied. The 

critical points are, as a rule, at relatively high. or low stages. 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 hiy 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 wellrated wooden flume of rectangular section there would result, other 

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

velocity, each plotting 0.5 foot above the original curves when 

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

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

reduces or increases all three values of discharge, area, and velocity
24 SURFACE WATER SUPPLY; 1909 PART X.

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 illustrative example of a station of this ^ type see stations of 

the south Atlantic coast drainage basins.

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
THE GEE AT BASIN. 25

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 examples of stations 

of this type see stations in the Platte, Arkansas, Rio Grande, and 

lower Colorado drainage basins.

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 feasible, by means of comparison with adjacent 

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

notes accompanying such estimates follow the daily and monthly 

discharge tables.

For most of the northern stations estimates have been made 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 much
26 SURFACE WATER SUPPLY, 1909 PART X.

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.

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

the purpose of making a measurement to determine the constancy of 

conditions of flow since the last measurement made during the preceding year, and also to check the elevation of the gage. On account 

of lack of funds or for other causes, some stations were not visited 

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

permanent up to the time of the last preceding measurement, it is 

considered best to publish values of discharge on the basis of the 

latest verified rating curve rather than to omit them altogether, 

although it should be distinctly understood that such records are at 

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

less degree, of the period of records since the date of the last measurement of the current year. As a rule the accuracy notes are based on 

the assumption that the rating curve used is strictly applicable to the 

current year.

In order to give engineers and others information regarding the 

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

daily discharge tables, stating the probable accuracy of the rating 

tables used, and an accuracy column is inserted in the monthly discharge table. For the rating tables "well defined" indicates in general that the rating is probably accurate within 5 per cent; "fairly 

well defined," within 10 per cent; "poorly defined" or "approximate," within 15 to 25 per cent. These notes are very general and 

are based, on the plotting of the individual measurements with reference to the mean rating curve.

The accuracy column in the monthly discharge table does not apply 

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

monthly mean. It is based on the accuracy of the rating, the probable reliability of the observer, and knowledge of local conditions. In
THE GEEAT BASIN. 27

+

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 

published, and hence allow more or less improvement in the computed results of earlier years. It is therefore expected that the 

engineer who makes serious use of the data given in these papers will 

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

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

republishing data for different drainage basins for five or ten year 

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

so far as the funds for such work are available.

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

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

is not expected that they will be used for other than preliminary 

estimates. The daily discharges are published to allow a more 

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

of deficient flow.

COOPERATIVE DATA.

Cooperative data of various kinds and also data regarding the 

run-off at many stations maintained wholly by private funds are 

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

Geological Survey.

Many stations throughout the country are maintained for specific 

purposes by private parties who supply the records gratuitously to 

the United States Geological Survey for publication. When such 

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

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

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

completely verify all such records furnished because of lack of funds 

or for other causes they are published for what they are worth, as
28 STJBFACE WATER SUPPLY, 1909 PAET X.

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

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

to be reasonably good.

COOPERATION AND ACKNOWLEDGMENTS. **"

_ The work in Utah in 1909 has been done in cooperation wifcJi the 

State. House bill No. 157, chapter 98, of the General Laws of 

Utah for 1909, approved March 22, 1909, contain the following:

Be it enacted by the legislature of the State of Utah:

SECTION 1. The state engineer shall make hydrographic surveys of each stream 

system and source of water supply in the State, beginning with those most used, 

obtaining and recording all available data pertaining to the water supply of the State. 

He is hereby authorised to cooperate with the agencies of the United States Gpvernment engaged in similar surveys and investigations. For the purpose of making 

hydrographic surveys, there is hereby appropriated from the general revenues of the 

State the sum of two thousand dollars ($2,000) annually, guch appropriation being 

contingent upon the United States making a like appropriation for such purpose, to 

be expended within the State.

An agreement was entered into July 1, 1909, between the Director 

of the United States Geological Survey and the state engineer of 

Utah for cooperative work under the provision of this act, whereby 

each party should contribute two thousand dollars ($2,000) for a 

survey to determine the amount of flowing water in the streams.

The principal provisions were substantially 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. Salaries of gage observers are paid from the state .funds; the 

salaries and traveling and field expenses of the engineers are divided 

between the two parties in some manner agreed upon, accounts being 

rendered monthly in accordance with the regulations of the Geological 

Survey.

4. The streams and localities in which investigation shall be made 

are determined by conference between the state engineer and the 

representative of the Geological Survey.

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

Survey.

Special acknowledgment is due to Mr. Caleb Tanner, state engineer 

of Utah, who Was constituted the agent of the State in carrying out 

the provisions of the act.

GENERAL DESCRIPTION OP THE GREAT BASIN.

In the interior of the North American Continent, west of the 

Rocky Mountains, is an immense.area known as the Great Basin, 

the streams of which do not discharge to the ocean. The area is not 

one single drainage basin, but consists rather of a number of basins, 

some of which are connected and others closed; the outer rim of all, 

however, is at such an elevation that the region as a whole has no 

surface outlet.

In outline the Great Basin is rudely triangular. It is bordered on 

the west by the Sierra Nevada, on the north by the Columbia plateaus, on the east by the Rocky Mountains and the Colorado plateaus, and the southern extremity extends almost to the Gulf of 

California. This inclosed area is approximately 800 miles long from 

north to south, 500 miles broad at its widest part, and has been estimated to include 208,000 square miles. It comprises the western 

part of Utah, almost all of Nevada, and contiguous parts of Idaho, 

Oregon, and California. *

Topographically this interior drainage area is characterized by 

isolated, narrow mountain ranges, trending north and south and 

separated by broad valleys varying considerably in altitude. In the 

southern part the valleys are low, Death Valley being below sea level;
30 SUEFACE WATEE SUPPLY, 1909 PAET X.

in the north the valleys have a general elevation of 4,000 to 5,000 

feet. Many of the intervening highlands rise several thousand feet 

above their bases, and some of the peaks of the bordering ranges 

attain elevations of 13,000 feet above sea level.

Upper branches of the intermontane valleys extend into the 

interior ranges as narrow drainage ways that are dry during most of 

the year; but the drainage from the high mountains on the east and 

west borders of the basin passes through deep canyons into the broad 

valleys, where the perennial streams maintain lakes. Among these 

are Great Salt, Utah, and Sevier lakes in the eastern part, and Pyramid, Winnemucca, Honey, Walker, Mono, and Owens lakes in the 

western part of the Great Basin. Except Utah Lake, which discharges by Jordan River into Great Salt Lake, these lakes are saline 

in character, as a consequence of the concentration of salts due to 

evaporation. Bear Lake, in the mountains of the eastern border, and 

Lake Tahoe, in the Sierra, are large bodies of fresh water that drain, 

respectively, to Great Salt and Pyramid lakes. Shallow, temporary 

bodies of water accumulate in some of the broad intermontane valleys 

during the wet season but completely evaporate during the summer, 

leaving muddy plains called playas.

Geologically the Great Basin is well known as the type region of 

the "basin-range structure." Many of the isolated narrow mountain 

ranges that trend north and south are steep on one side, exposing 

cross sections of the rocks, and sloping on the other, conforming with 

the dip of the strata. These ranges have been uplifted by movements 

of the earth's crust which have broken it into tilted blocks. The 

greatest displacements of the Great Basin are associated with the 

eastern and western borders, the Wasatch Mountains and the Sierra 

Nevada having been uplifted many thousand feet. The mountains 

of the Great Basin are commonly composed of Paleozoic strata, often 

modified by volcanism, and the products of weathering and disintegration of these rocks have accumulated in the broad intervening 

valleys which are strewn to great depths with unconsolidated debris.

The climate of the Great Basin is extremely arid, and except in a 

few favored spots where irrigation is practiced the region in general is 

a desert. Over the larger part of the area the precipitation is less 

than 10 inches, but it is greater on the bordering highlands, especially 

on the Sierra Nevada, where it is over 40 inches. The temperature 

varies widely, owing to the large extent of the area and to differences 

in elevation. Over most of the region the heat of the summer days 

is intense, but the diurnal variation is considerable. Evaporation is 

enormous. From the surface of the water in the vicinity of Salt 

Lake City it amounts to about 60 inches in a year, and over the 

major part of the Great Basin it is much greater, amounting in places 

to possibly 150 inches.
THE GREAT BASIN. 31

An arid climate, however, has not always prevailed in this region. 

In late geologic time (early Quaternary) the bordering high mountains supported glaciers and enormous lakes, the old shore lines of 

which are now plainly marked on the sides of many valleys, accumulated in the Great Basin. The two largest of these lakes have been 

named after early explorers. Lake Bonneville occupied a considerable part of western Utah, its shrunken remnants being represented 

by Sevier, Utah, and Great Salt lakes; and Lake Lahontan covered 

an immense area in western Nevada.

The chief rivers of the Great Basin rise in the mountains which form 

its eastern and western borders and receive their principal supply 

from melting snow. The nature of the stream discharge is characteristic ; the maximum commonly occurs in late spring or early summer, after which the flow decreases, reaching a minimum during the 

winter months. After leaving the mountains the streams receive 

little or no increment; in the broad, waste-filled valleys evaporation 

and seepage cause diminution in size, and often they entirely cease 

to flow.

For convenience of treatment the drainage of the Great Basin has 

been divided into four areas, viz, Wasatch Mountains, Humboldt 

Sink, Sierra Nevada, and Great Basin drainage in Oregon. The data 

collected in these areas during 1909 are given in the following pages.

WASATCH MOUNTAINS DRAINAGE AREA.

PRINCIPAL STREAMS.

The Wasatch Mountains drainage area includes the western half 

of Utah and small portions of Idaho and Wyoming. The various 

streams head either in the Wasatch Mountains or in the plateaus to 

the south, 'and discharge into Great Salt Lake or Sevier Lake. The 

following are the principal rivers of the area:

Bear and Weber rivers, discharging into Great Salt Lake.

City, Red Butte, Parleys, Emigration, Mill, and Big and Little 

Cottonwood creeks, tributary to Jordan River and thus to Great Salt 

Lake. These creeks have small drainage areas, but in their mountain courses maintain perennial flows. On reaching the main valley 

they are extensively used for irrigation, and City, Parleys, and Emigration creeks furnish the chief water supply for Salt Lake City.

American Fork, Hobble Creek, Spanish Fork, and Provo River, 

discharging into Utah Lake.

Sevier River, with its tributary San Pitch River, draining into 

Sevier Lake, and Beaver River, nominally a part of the Sevier Lake 

drainage, but only a small portion of its highest floods ever reach 

the lake.
32 SURFACE WATER SUPPLY, 1909 PART X.

BEAU RIVER BASIN.

DESCRIPTION.

Bear River rises on the northern slope of the Uinta Mountains, in 

the northeastern part of Utah, and after a circuitous course in 

which it leaves Utah and enters Wyoming, reenters Utah, appears 

again in Wyoming, and makes a long detour in Idaho it returns to 

Utah and finally discharges its waters into Great Salt Lake. The 

maximum elevation of the upper rim of the basin is 13,000 feet.

In the upper part of its course, above the Dingle gaging station, 

the country is rough and broken, the rocks of the extreme headwater 

regions being principally sandstone and quartzite covered with a thin 

layer of soil, which supports scattered groves of fir and aspen. Farther down the prevailing formation is a compact limestone covered 

with a clayey soil, generally dry and with a rank growth of sagebrush. 

The tributary streams are numerous and well distributed, but most 

of them are short and confined to steep, narrow canyons. The basin' 

contains no marshes, extensive meadows, .or forests, but a few small 

lakes lie near the head of the river. The greater part of the precipitation is in the form of snow. Numerous small springs and the melting snow are the chief sources of supply of the streams. The annual 

high-water period occurs during May and June, and the stream is 

not subject to quick floods or freshets.

Just below Dingle the main stream passes through the north end of 

Bear Lake valley in a well-defined channel with no overflow, and 

from this point to Preston it is confined largely to a steep-walled 

canyon, interrupted by occasional short, narrow valleys containing 

irrigated farms. The tributaries in this portion of the basin are few, 

the principal ones being Mink and Cottonwood creeks. About 10 

miles below Dingle the outlet to Bear Lake joins the river. This is a 

small, crooked, sluggish stream that discharges but little water at any 

time, though it is the only visible outlet to Bear Lake, which, has an 

area of about 144 square miles.

The total unappropriated flow between Dingle and Preston is used 

for irrigation. There is no storage on the main stream, but on Mink 

Creek a number of small storage reservoirs are contemplated or in 

process of construction, the water to be diverted for the irrigation of 

lands in the northwest end of Cache Valley.

Between Preston and the lower end of Cache Valley the. Bear flows 

sluggishly along the west side in a well-defined channel, and during 

extreme floods overflows slightly and covers a very narrow strip 

immediately along the river. The principal tributary streams in this 

portion of the course are Cub Creek and Logan River. Cub Creek 

rises in the Bear River Range and drains a rough limestone country 

with but little overlying soil. The creek is confined to a steep, narrow canyon until it reaches Cache Valley, where it flows sluggishly
THE GREAT BASIN. 33

for about 15 miles through a winding, but well-defined, channel into 

Bear River. It discharges considerable water into the main stream 

during flood and winter seasons, but its entire summer flow is used for 

irrigation in the north end of Cache Valley. A gaging station was 

maintained during a part of 1900 and 1901 on Cub Creek about 4 

miles northeast of Franklin, at the mouth of the canyon, but owing 

to unfavorable conditions it was discontinued.

Logan River enters the Bear about 7 miles above the gaging station at Collinston, a short distance above the point where it leaves 

Cache Valley and enters the canyon.

Practically the only inflow to the Bear in Cache Valley is from 

seepage and springs. The lower portions of the valley form an 

artesian basin containing numerous small, flowing wells. The water 

table lies very near the surface, and during the early spring the lower 

lands are largely swamp.

The Bear River Canal Company diverts the entire summer flow of 

the stream above Collinston onto agricultural lands lying on both 

sides of the river below Bear River canyon. This system has a 

capacity of 1,000 second-feet, and during the winter and flood seasons a part of the water is used to develop electric power at a point 

about one-fourth mile above the Collinston station and is returned 

to the river at Collinston. From 10 to 30 second-feet reaches the 

stream through leaks and as seepage from the diversion canals.

Owing to the complete control of the stream by irrigation works 

the discharge is liable to extreme variation at any period.

Within the periods for which records are available the wettest year 

was 1907, the run-off at Collinston in the year being 2,680,000 acrefeet; in 1890, 1894, 1897, 1899, and 1909 the run-off was also high, 

the total for each of these years exceeding 2,000,000 acre-feet. The 

driest year was 1905, when the run-off at Collinston, Utah, was only 

701,000 acre-feet.

Gaging stations have been maintained in this basin as follows:

Bear River at Dingle, Idaho, 1903-1909.

Bear River near Preston, Idaho, 1889-1909.

Bear River near Collinston, Utah, 1889-1909.

Bear Lake at Fishhaven, Idaho, 1904-1906.

Cub Creek near Franklin, Idaho, 1900-1901.

Logan River near Logan, Utah, 1896-1909.

Logan, Hyde Park, and Smithfield canal, 1904, 1906-7, 1909.

Blacksmith Fork near Hyrum, Utah, 1900-1909.

Blacksmith Fork power plant race near Hyrum, Utah, 1904-1909.

Box Elder Creek at Brigham, Utah, 1909.

BEAR RIVER AT DINGLE, IDAHO.

This station, which was established May 9, 1903, to determine the 

run-off available for storage in Bear Lake, is located in a cut-off 

built by the Oregon Short Line Railroad Company one-fourth mile 

63150° WSP 270 11 3
34 SURFACE WATER SUPPLY, 1909 PART X.

east of Dingle railroad station, about 10 miles above the outlet of 

Bear Lake, below the proposed intake of the diversion canal to the 

lake. There is some diversion for irrigation above this point.

Measurements are made from a car and cable. The inclined 

staff gage is located near the cable and its datum has remained 

unchanged since the station was established.

'The records at this station are not affected by artificial control 

above or below, but the river is usually frozen over during the period 

from December 1 to March 31, the ice reaching a thickness of 14 or 

15 inches, this, however being a smooth cover, no anchor or needle 

ice ever having been known to form.

The conditions during the open-water season at this station are 

excellent, and fairly accurate estimates of the flow under ice have been 

made, so that, on the whole, the records at this station may be considered excellent.

The following discharge measurement was made at this station 

by W. M. O'Neill:

May 6, 1909: Width, 121 feet; area, 556 square feet; gage height, 6.94 feet; 

discharge, 2,110 second-feet.

Daily gage height, in feet, of Bear River at Dingle, Idaho, for 1909.

NOTE. The daily discharges from April to November are based on a rating curve well denned between 

390 and 3,180 second-feet. Discharges interpolated for days of missing gage heights during this period. 

During the periods of ice conditions the discharges were estimatedf rom the 1908 ice curve and the observer's

notes on ice conditions.

36 SURFACE WATER SUPPLY, 1909 PART X.

BEAR RIVER NEAR PRESTON, IDAHO.

This station, which was established October 11, 1889, and has since 

been continuously maintained, is located just below the wagon bridge 

on the road from Preston to Battle Creek, at a point about 4J miles 

northwest of Preston, Idaho, and about 10 miles north of the IdahoUtah state line. The records show practically the amount of water 

passing from Idaho into Utah and will be of value in the final adjudication of water rights.

No important tributaries enter above the station; those coming in 

below are Battle Creek, entering a few hundred feet below the station, and Cub Creek and Logan River, entering in Cache Valley, 

about 18 and 40 miles, respectively, below the station. There are at 

present no important diversions above the station, although the river 

passes through large areas of irrigable land.

The river seldom freezes over at the station; but the flow is sometimes slightly affected by the presence of slush ice. The channel 

shifts slightly during floods; but the conditions for measurement are 

always good.

Discharge measurements are made from a cable and car, about 300 

feet below the bridge. A new gage was installed, April 3, 1909, below 

the cable at a point about 200 feet below the old gage and reads 0.05 

foot lower than the old gage. The new curve was found to be parallel 

to the old curve, and the gage heights taken during 1909, previous to 

the establishment of the new gage, have been referred to the new gage 

datum. The estimates of flow at this station may be considered 

excellent.

BEAR RIVER NEAR COLLINSTON, UTAH.

This station, which was established July 1, 1889, and has been 

continuously maintained since, is located in the lower end of the Bear 

River canyon, about 6 miles north of the Collinston railroad station 

and about one-fourth mile below the Telluride power plant. 'The 

records show practically the amount of unappropriated water below 

all diversions.

The principal tributaries above are Cub Creek and Logan River; 

the only tributary below is Malade River, which enters 18 or 20 miles 

below the station. Most of the normal low-water flow of the river 

at this point is appropriated by the Bear River Canal Company, 

which diverts water at a point about 2 miles above the station. The 

Telluride Power Company also diverts water about 2 miles above the 

station for power development, but returns it to the river above the 

station.

Measurements are made from a car and cable.

The records are not affected by artificial control below, but some 

variations in daily flow may be caused by manipulation of gates on 

the dam 2 miles above the station. A little shore ice occasionally 

forms at the station, but the effect on the discharge is very slight. .

The channel is fairly permanent, the measuring conditions are 

good, and the records may be considered excellent. The datum of 

the inclined staff gage has remained unchanged.

LOGAN RIVER BASIN.

DESCRIPTION.

Logan River rises on the west slope of the Bear River Range, flows 

southwest, then northwest, and unites with Bear River near Benson, 

Utah. The entire basin is rough and rugged, the elevations ranging 

from 4,500 to 9,000 feet, and the stream being confined largely to a 

steep and rough channel in a comparatively narrow canyon. The 

principal rock is a compact limestone with little or no soil covering 

except near the summit of the range, where a thin layer supports 

large groves of fir and aspen. The lower reaches of the stream are 

practically barren of timber except for a few scattered pines and a 

growth of underbrush. A large amount of timber has been cut and 

the area has been overgrazed by sheep and cattle.

Probably three-fourths of the precipitation in the basin is snow, 

the melting of which forms the chief source of supply for the spring 

and early summer flow; the late summer and winter flow is derived 

chiefly from springs, which are well distributed over the basin.

In its upper course the Logan receives many short, swift tributaries. 

Temple Fork and South .Fork, which enter, respectively, about 10 

and 15 miles above Logan, are perennial streams and furnish onethird to one-fourth of the total flow. Blacksmith Fork comes in 

below the Logan gaging station. None of the run-off is stored at 

present. The entire flow of the river, after being used to develop 

power at two electric plants near the mouth of the canyon, is diverted 

for irrigation.
THE GREAT BASIN. 41

LOGAN RIVER NEAR LOG AN, UTAH.

This station, which was established June 1, 1896, discontinued 

July 18, 1903, and reestablished April 13, 1904, is located about 2 

miles east of Logan, Utah, about one-fourth mile below the Hercules 

power house, near the mouth of the canyon. The records show the 

total amount of water available for irrigation in the valley below.

The station is below all tributaries except Blacksmith Fork and 

Cache River, which enter about 5 and 10 miles, respectively, below 

the station. Water is diverted above the station to develop power, 

but is returned to the river above the station. The Logan, Hyde 

Park, and Smithfield canal diverts above the station, and records 

have been kept on this canal in order that the total flow from the 

drainage area might be determined. Practically all the normal low 

water flow is diverted for irrigation below the station.

The equipment consists of a car and cable and an inclined staff 

gage.

The records are not affected by artificial control nor by ice conditions, but the high velocity at the station causes shifting of the 

bed of the stream and makes the measuring conditions rather unfavorable. The results are therefore liable to some error, but may be. 

considered fairly good. The gage datum has remained unchanged 

since January 1, 1906.

LOGAN, HYDE PARK, AND SMITHFIELD CANAL NEAR LOGAN, UTAH.

This canal diverts water for irrigation and domestic use in Logan, 

Hyde Park, and Smithfield. Records are fragmentary. Gage 

heights are available for parts of 1904 and 1905, for the entire year 

1906, and for parts of 1907 and 1909.

The channel is permanent, and a rating curve has been developed 

from measurements made in 1909. These discharges, so far as are 

available, have been added to those at-the station on Logan River 

at the mouth of the canyon in order to determine the total flow of 

the river. The total amount diverted by the canal during 1909 was 

26,300 acre-feet.

The gage in the canal is above a spillway which discharges into 

the river above the station. No record was kept of the amount 

spilled in 1909, but it probably ranged from 2 to 5 second-feet, and 

the discharges of the canal as given are too large by this amount.

THE GREAT BASIN. 45

BLACKSMITH FORK AND POWER-PLANT RACE NEAR HYRUM, UTAH.

Blacksmith Fork rises on the western slope of the Bear River 

Range and flows southwest and then northwest into Logan River. 

The drainage basin of the tributary is in every way similar to that of 

the main stream. Only the flood and winter discharge, however, 

reaches the Logan, the entire spring and summer flow being used for 

irrigation on the tillable lands below the gaging station.

The station, which was established July 19, 1900, discontinued 

December 31, 1902, and reestablished May 16, 1904, is located at the 

mouth of the canyon, about 10 miles southeast of Logan and about 5 

miles from Hyrum, the nearest railway and post-office point. It is 

about 800 feet above the Hyrum city power plant and about 500 feet 

below the intake of the power canal. A station was established on 

the power-plant race on May 16, 1904, and the total flow from the 

drainage area since that date is given by the sum of discharges at 

these two stations. The original station was above the intake of the 

power canal. The records show the total amount of water available 

for irrigation in the valley belo,w.

The equipment consists of a car and cable and a vertical staff gage. 

The flow is not affected by artificial control above or below the station or by ice at either gage. The velocity at the river station is very 

high., and a slight shifting of channel during high water makes the 

records somewhat liable to error. The results, however, may be 

considered fairly good. Gage heights on the power-plant race for 

1909 are very uncertain and have not been published. The gage 

datum has remained unchanged since the new stations were established in 1904.

BOX ELDER CREEK AT BRIGHAM, UTAH.

Box Elder Creek is tributary to Box Elder Lake, about 3 miles 

northwest of Brigham, Utah. At high stages the water may reach 

Bear River. The gaging station, which was established May 20, 

1909, to determine the amount of unappropriated water passing this 

/ point, is located about three-fourths of a mile northwest of Brigham 

City, Utah, on the Third West Street Bridge, and about one-half 

mile above the Oregon Short Line Railroad crossing. The gage is 

of the vertical type and is located on the northwest corner of the 

bridge.

The records are not affected by ice conditions or by artificial control above or below the station. The gage heights observed at this 

station are believed to be unreliable and no records can be worked 

up from 1909 measurements.

WEBER RIVER BASIN. 

DESCRIPTION.

Weber River rises on the northern slope of the Uinta Mountains 

and flows in a tortuous course northwestward into Great Salt Lake.

The upper portion of the basin is very rough. The highest peaks, 

reaching an elevation of about 13,000 feet, are masses of sandstone 

and quartzite, barren of vegetation and covered with snow for almost 

the entire year. Farther down the prevailing formation is limestone overlain with sandstone and conglomerate. A thin layer of 

soil covers the basin in patches and supports small groves of fir and 

aspen. The basin contains no extensive forests, meadows, or marshes. 

The greater part of the precipitation is in the form of snow, the melting of which is the chief source of the spring flood and early summer 

flow. A large part of the normal flow is derived from springs, which 

are well distributed over the area. Many tributaries, all short and 

confined to steep, narrow canyons, enter all along the course.

Between Oakley and Croyden the river traverses a very narrow 

valley comprising irrigated farms. The principal rock formation 

over this area is of conglomerate and sandstone, with but little 

loose and porous overlying soil except near the stream bed, where 

the deposit of bowlders and soil varies from 10 to 20 feet in depth. 

The chief tributaries in this stretch of the river are Beaver Creek, 

which enters from the south about 6 miles below Oakley and drains a 

rough country about 71 square miles in extent; Chalk Creek, from the 

east, which drains a rough, dry country about 428 miles in area and 

enters the Weber 15 miles above Croyden; and Lost Creek, which 

comes in from the east at a point about one-half mile above the Devils 

Slide gaging station and has a drainage area of 205 square miles.

Between Croyden and Plain City the stream flows in a well-defined 

channel through a comparatively narrow, steep canyon, with occasional stretches of valley containing irrigated farming lands. The 

rock is a porous and badly fissured sandstone and conglomerate, 

with but very little overlying soil. Near the mouth of the canyon 

the material is a very rough but compact limestone. East Creek, 

which enters near Morgan, discharges but little water into the river, 

as its flow is completely controlled by a storage reservoir about 

5 miles above its mouth, the water being used for irrigation in Morgan 

Valley, through which the Weber flows. After leaving the Wasatch. 

Range the Weber enters Great Salt Lake valley, through which it 

flows in a well-defined channel with no overflow.

Ogden River joins the Weber about 8 miles above Plain City. It 

drains a rough and rugged limestone area, 363 square miles in extent, 

in the western slopes of the Wasatch Range. The main stream and 

its numerous small tributaries are confined to steep, narrow canyons. 

The entire normal flow of the stream is diverted for irrigation near
THE GREAT BASIN. 49

the foot of the canyon about 3 miles above the mouth of the river, 

after being used for the development of power by the Utah Light and 

Railway Company. The flood and winter flow, therefore, is all that 

reaches the Weber, except for a small amount of seepage from the 

irrigated district. The city of Ogden also derives its water supply 

from Ogden River.

&t present no storage reservoirs are used on the Weber, but a 

number of sites are available.

The wettest year since records have been kept was 1909, when 

1,290,000 acre-feet wasted into Great Salt Lake from the Weber 

basin, as shown by the records at the Plain City station. The year 

1905 was by far the driest year, when only 298,000 acre-feet wasted 

into Grreat Salt Lake.

The gaging stations maintained in this basin are as follows:

Weber River near Oakley, Utah, 1904-1909.

Weber River at Devils Slide (Croydon), Utah, 1905-1909.

Weber River near Uinta, Utah, 1889-1901, 1903.

Weber River near Plain City, Utah, 1903-1909.

Lost Creek near Croydon, Utah, 1905.

Chalk Creek at Coalville, Utah, 1904-5.

Ogden River at Ogden, Utah, 1895-1901.

WEBER RIVER NEAR OAKLEY, UTAH.

This station, which was established October 22, 1904, is located 

near the mouth of the canyon above Kamas Prairie, about 3 miles 

above Oakley, Utah, the nearest post-office. The records show 

the total amount of water available for diversion through Kamas 

Pass into Provo River in connection with the proposed Weber River 

project.

The station is below South Fork and above Kamas Creek and is 

above all diversions to the Kamas Prairie region.

Measurements are made from a cable and car.

The river freezes over at the station at times during the winter 

season, but as the winter flow is fairly constant good results are 

obtained by interpolating between periods when the river is known 

to be open.

The bed of the stream is fairly permanent and the results may be 

considered good. The datum of the inclined staff gage has remained 

unchanged since the station was established.

WEBER RIVER AT DEVILS SLIDE, UTAH.

This station, which has formerly been called Weber River near 

Croydon, was established February 1, 1905, to determine the amount 

of water available for storage in the Henefer basin, about 2 miles 

above the station, in connection with the proposed Weber River 

project. It is located at the new town of Devils Slide, about 1J 

miles west of Croydon and 10 miles below Echo.

Lost Creek is tributary about one-fourth mile above the station 

and Chalk Creek enters about 15 miles above. The only diversions 

above are those for irrigation in Kamas Prairie and in the narrow 

valleys above the station.

Measurements are made from a cable and car.

The river never freezes over at the station although slush ice runs 

at times. This ice, however, does not seriously affect the discharge. 

The channel is fairly permanent and the measuring conditions are 

good. The records are not affected by artificial control above or 

below the station and may be considered excellent. The datum 

of the staff gage has remained unchanged since the station was 

established.

WEBER RIVER NEAR PLAIN CITY, UTAH.

This fetation was established in 1903 under the direction of the state 

enginee[r and was maintained by the State of Utah until May 14, 1905, 

when it was taken up by the United States Geological Survey, by 

whom it has since been maintained in cooperation with the State. 

It is located at the highway bridge on the main road to Plain City and 

West Weber, about 10 miles northwest of Ogden, Utah, and about 6 

miles above the mouth of the river.

The station is below all tributaries and diversions, Ogden River 

entering about 8 miles above the station. The records show the total 

amount of water discharged into Great Salt Lake and will be valuable 

in the adjudication of water rights on the Ogden and Weber rivers.

Discharge measurements are made from the bridge. The upstream 

face of i the center bridge pier is graduated, marked with white paint, 

and foi[ms the gage.

The records are very little affected by ice, although the river 

freezes at times near the station. There is no effect from artificial 

control} above or below the station, and as the bed of the stream 

changes only very slightly the records may be considered excellent.

JORDAN RIVER BASIN. 

DESCRIPTION.

Jordan River rises in Utah Lake and discharges into Great Salt 

Lake about 5 miles northwest of Salt Lake City. The discharge of 

the river is entirely controlled, and most of the water is diverted into 

canals for irrigation in Salt Lake County.

The principal tributaries of Jordan River are from the Wasatch 

Mountains to the east, and in order from south to north they are Little 

Cottonwood, Big Cottonwood, Mill, Parleys, Emigration, Red Butte, 

and City creeks. Measurements of all these streams except Red Butte 

Creek were begun by F. C. Kelsey, the city engineer of Salt Lake City, 

in-the fall of 1898. The discharges have been measured by weirs near 

the lower end of the canyon, thus giving the total flow of the creek, 

available for irrigation or city water supply. The records are incomplete for some of the stations, but otherwise are excellent.

The daily discharges for these stations for 1909 and the monthly 

discharge for the entire period covered by the records are published 

below through the courtesy of G. F. McGonagle, city engineer of 

Salt Lake City.

LITTLE COTTONWOOD CREEK NEAR SALT LAKE CITY, UTAH.

Little Cottonwood Creek is the most southern of the streams 

tributary to Jordan River on which records have been obtained. The 

flow is measured over two 15-foot Cippoletti weirs, located near the 

mouth of the canyon.

BIG COTTONWOOD CREEK NEAR SALT LAKE CITY, UTAH.

Big Cottonwood Creek, the largest tributary of Jordan River, 

rises near Clayton Peak, which reaches an elevation of over 12,000 

feet. Its headwaters are very mountainous (see PL III) and heavily 

timbered. The discharge is measured near the mouth of the canyon 

by means of a compound weir (see PL IV), which serves not only to 

measure the water, but to distribute it among the various claimants. 

The weir is just below the power plant of the Utah Power Company, 

the operation of which, causes a diurnal fluctuation in the discharge.

PROVO RIVER BASIN.

DESCRIPTION.

Provo River rises in the Uinta Mountains and flows westward in a 

steep, narrow canyon until it reaches Heber or Provo Valley, through 

which it winds in a well-defined channel. Leaving the valley it flows 

southwestward, cutting through the Wasatch Range in another steep, 

narrow, and extremely rough canyon, and finally discharging its 

surplus waters into Utah Lake.
72 SURFACE WATER SUPPLY, 1909 PART X.

In the mountain regions the principal rock is a compact limestone. 

Except in Heber Valley little soil is found in any part of the basin. 

Small groves of fir and aspen are, however, scattered over almost the 

entire area, and there is a light growth of underbrush. No extensive 

forests, meadows, or marshes exist. In the canyons the stream 

receives numerous short and swift tributaries which derive their 

principal supply from springs, but a part also from the melting of the 

snow that covers portions of the mountains during the entire year. 

The highest peaks reach elevations of about 13,000 feet above sea 

level.

Heber Valley, comprising an area of about 20 square miles, is an 

irrigated farming district. The surface is covered with loose bowlders, 

gravel, and very porous soil. Most of the water is taken from the 

main stream, but a part is diverted from small creeks that enter the 

valley from the south. The most important of these is Daniels 

Creek, into which some water is diverted from Strawberry River, a 

tributary of Green River, by three small canals in low passes at the 

head of the creek.

At the head of the river are a few lakes, but they are so small that 

they probably have little effect in regulating the flow. No storage 

is used on the stream at present, but a few favorable sites will doubtless be developed in the future, as the entire flow, after being used by 

a power plant at the mouth of the canyon, is now utilized in the 

vicinity of Utah Lake, and the supply is altogether insufficient.

The wettest year since records have been kept in this basin was 

1907, when the discharge at the station of the Telluride Power Company's dam was 477,000 acre-feet. The driest year was 1905, when 

at the same station the discharge was 192,000 acre-feet.

The following stations have been maintained in this basin:

Provo River above Telluride Power Company's dam near Provo, Utah, 1905-

1909.

Provo River at mouth of canyon, near Provo, Utah, 1889-1906. 

Provo River at Denver and Rio Grande Railroad bridge, near Provo, Utah, 1905. 

Provo River at San Pedro, Los Angeles and Salt Lake Railroad bridge, near

Provo, Utah, 1903-4.

PROVO RIVER ABOVE TELLURIDE POWER COMPANY'S DAM NEAR PROVO,

UTAH.

This station, which was established February 1, 1905, to determine 

the amount of water available for irrigation in Utah Valley, is located 

about 1 mile above the Telluride Power Company's dam and about 4 

miles above the mouth of the canyon and about 11 miles from Provo.

The station is below all tributaries, South Fork entering about onefourth mile above the station. Some water is diverted above the 

station for irrigation in Heber Valley, and all the normal low-water
THE GREAT BASIN. 73

flow is diverted for irrigation below the station. The Telluride 

Power Company diverts water about 1 mile below the station for 

power development, but returns it to* the river at the mouth of the 

canyon.

The equipment consists of a cable and car and an inclined staff gage. 

The gage datum was changed July 24, 1908, when the station was 

established at a point one-fourth mile above the old site.

The records are not affected by ice nor by artificial control above, 

but there seems to be some backwater effect either from the dam 

below the station or from some unknown cause, and the records since 

the dam was raised in July, 1908, have not been satisfactory.

74 SURFACE WATER SUPPLY, 1909 PART X.

HOBBLE CREEK BASIN. 

DESCRIPTION.

Hobble Creek rises on the western slope of the Wasatch Mountains 

and flows in a general southwesterly direction to Utah Lake. In 

the greater part of the basin the soil cover is very thin and supports 

but a scanty growth of timber and brush. The steep, narrow canyon 

in which the stream flows is broken here and there by narrow openings 

or flats, covered with a shallow deposit of bowlders and soil and 

comprising irrigated farms. As these tracts lie along the banks of 

the creek, a large part of the water used on them is returned to the 

stream as seepage. The creek has no important tributaries, but 

short intermittent streams which flow in steep, narrow canyons 

enter all along the course. No storage reservoirs, lakes, or marshes 

control the flood discharge, which occurs in the spring as a result of 

the melting snow. The entire normal summer flow is used for 

irrigation below the canyon.

Within the period for which records are available, the year of the 

greatest run-off was probably 1909, or possibly 1907, but records are 

not complete for that year. The driest year, according to the record 

at Springville, was 1905, when the discharge was 21,650 acre-feet.

Only one station has been maintained in this basin, that near 

Springville, Utah, 1904-1909.

HOBBLE CREEK NEAR SPRINGVILLE, UTAH.

This station, which was established March 23, 1904, to determine 

the amount of water available for irrigation in Utah Valley in connection with the Strawberry Valley project of the United States Reclamation Service, is located at a point about 1 mile above the mouth of 

the canyon, 4 miles southeast of Springville, Utah, and just below the 

Springville electric power plant. The station is above all diversions 

and below all tributaries.

Practically no ice forms at the station, the winter flow being largely 

from springs. In May, 1909, a flood tore out the old gage and changed 

the section to s,uch an extent that it was found advisable to change the 

location of the station. A new vertical staff gage was therefore 

installed at a point about 1,000 feet upstream from the old gage and 

about 200 feet below the power plant.

Measurements are made from a cable and car or by wading. The 

bed of the stream at this point is more nearly permanent than at the 

old station. A good rating curve has been obtained, and the records 

at the new station may be considered excellent. All gage heights since 

June 1, 1909, refer to the new gage.

NOTE. The daily discharges from January 1 to May 31 are based on a rating curve which is not well 

defined for 1909. The rating after June 1 is for the new station and is well defined. Daily discharges for 

days of missing gage heights were obtained by interpolation and from high-water marks.

THE GREAT BASIN. 77

SPANISH FORK BASIN. 

DESCRIPTION.

Spanish Fork rises in the Wasatch Mountains and flows northwestward into Utah Lake. The area is generally barren and supports 

but little timber or brush. The stream flows in a steep, narrow 

canyon, with a very few small openings in which are irrigated farms. 

The tributaries are all short and many of them are intermittent. 

The most important, Diamond Fork and Thistle Creek, enter, respectively, about 8 and 10 miles above the gaging station, near Spanish 

Fork, and, like the main stream, occupy narrow, steep-walled canyons. 

The normal flow comes largely from springs scattered over the entire 

basin; the flood discharge is direct surface run-off from melting snow.

No storage reservoirs are used on the stream. The entire normal 

low-water flow is diverted at the mouth of the canyon and used for 

irrigating lands near Utah Lake.

The stream at present is used for power development at one plant 

installed in 1908 by the United States Reclamation Service, near the 

mouth of the canyon.

During the period for which records are available the wettest 

year was 1909, when discharge at the station at the mouth of the 

canyon near Spanish Fork, including that of the power canal, was 

228,000 acre-feet, of which about 160,000 acre-feet wasted into Utah 

Lake, according to the records at the Lake Shore station, which are 

not quite complete. The driest year, according to the above records, 

was 1905, when 65,810 acre-feet were discharged at the mouth of the 

canyon, of which 19,230 acre-feet wasted into the lake.

The following stations have been maintained in this basin:

Spanish Fork at Thistle, Utah, 1909.

Spanish Fork near Spanish Fork, Utah, 1900-1909.

United States Reclamation Service power canal near Spanish Fork, Utah, 1909.

Spanish Fork near Mapleton, Utah, 1900-1901.

Spanish Fork near Lake Shore, Utah, 1903-1907, 1909.

Diamond Fork near Thistle, Utah, 1908-9.

SPANISH FORK AT THISTLE, UTAH.

This station, which was established December 3, 1907, to determine the amount of water available for irrigation and power development in connection with the Strawberry Valley project of the United 

States Reclamation Service, is located half a mile below Thistle station 

on the Denver and Rio Grande Railroad.

Thistle Creek enters about one-half mile above the station and 

Diamond Fork conies in about 2 miles below. There are no important 

diversions above the station,
78 SURFACE WATER SUPPLY, 1909 PART X.

The river usually freezes over at the station during two or three 

months in the winter, but as the winter flow is fairly constant good 

estimates may be made. The records are not affected by artificial 

control.

Although the section is somewhat shifting, many measurements 

have been made and the results may be considered excellent. The 

equipment consists of a vertical staff gage and a cable and car. The 

gage datum has remained unchanged since the station was established.

80 SURFACE WATER SUPPLY, 1909 PART X.

SPANISH FORK NEAR SPANISH FORK, UTAH.

This station, which was established May 23, 1900, discontinued 

November 30, 1901, and reestablished March 26, 1903, to determine 

the total water available from Spanish Fork for irrigation near Utah 

Lake, is located in the mouth of the canyon, 600 feet above the 

diversion dam of the East Bench Irrigation Company and about 5 

miles southeast of Spanish Fork, Utah. The records are of special 

importance to the United States Reclamation Service in connection 

with the Strawberry Valley project.

The station is below all tributaries and above all important diversions except the Reclamation Service power canal, which diverts 

water at a point about one-half mile above the station. The water 

thus diverted is used to develop power, after which a part of the 

water is returned to the river, the remainder being turned into the 

Salem canal and used for irrigation. The entire low-water flow of 

the river below the station is used for irrigation. The amount of 

water diverted is measured and added to the discharge of the river.

The records are little affected by ice and show no effect from 

artificial control below, but variations in daily flow are caused by 

manipulation of gates on the Reclamation Service diversion dam 

above.

Measurements are made from a cable and car.

Although the section is somewhat shifting, numerous measurements have been made and the results obtained are excellent. The 

datum of the staff gage has remained unchanged since the staion 

was established.

NOTE. These discharges are for the combined discharge of the river and power canal.

UNITED STATES RECLAMATION SERVICE POWER CANAL NEAR SPANISH

FORK, UTAH.

This station, which was established January 1, 1909, to determine 

the amount of water diverted by the Reclamation Service for power 

in connection with the Strawberry Valley project, is located in the 

mouth of the canyon at a point about 1J miles below the canal head 

gates and about 5 miles southeast of Spanish Fork, Utah.

The station is located in the middle of a long tangent on the canal, 

which is smoothly lined with concrete. A good rating curve has 

been obtained and the records may be considered excellent. The 

gage datum has remained unchanged since the station was established.

The discharge of this canal has been added to that of the river at 

the station near Spanish Fork, just below, to give the total discharge 

of Spanish Fork above the diversions.

SPANISH FORK AT LAKE SHORE, UTAH.

This station, which was established December 10, 1903, discontinued July 10, 1907, and reestablished March 10, 1909, to determine 

the amount of water wasted into Utah Lake, is located about 3 miles 

west of Spanish Fork, Utah, 1 mile east of Lake Shore, and about 

3 miles above the mouth of the river.

The station is below all tributaries and diversions, all the low-water 

flow being diverted above. The station was originally located about 

800 feet above the wagon bridge on the road from Spanish Fork to 

Lake Shore, but as the conditions were very unsatisfactory it was 

relocated at a point about one-half mile farther downstream, where 

the measuring conditions are excellent.

Measurements are made from a cable and car.

The records are not affected by ice or artificial control below. The 

bed of the stream is fairly permanent at the new station, a good 

rating curve has been obtained, and the 1909 records may be considered excellent. The datum of the staff gage has remained 

unchanged since the new station was established.

DIAMOND FORK NEAR THISTLE, UTAH.

This station, which was established December 2, 1907, to determine 

the amount of water available for irrigation and power development 

in connection with the Strawberry Valley project of the United 

States Reclamation Service, is located about 2^ miles northwest of 

Thistle, Utah, and about one-fourth mile above the mouth of the 

river.

As the station is below all tributaries and there are no important 

diversions above or below, the records show the total run-off from 

the Diamond Fork drainage area.

Discharge measurements are made from a footbridge. The gage 

is an inclined staff near the bridge.

The river is frozen over at the station during several months, but 

as the winter flow is fairly constant good estimates may be made. 

The records are unaffected by artificial control. Although the section shifts a great deal throughout the year, many measurements 

were made in 1909 and the records may be considered good. The 

gage datum has remained unchanged since the station was established.

PAYSON CBJJEK BASIN. 

PAYSON CREEK NEAR PAYSON, UTAH.

Payson Creek rises on the south of Spanish Fork at an elevation 

of about 7,000 feet above sea level and flows northwestward to Utah 

Lake. One station has been maintained in this basin, that near 

Payson, Utah, 1908-9.

This station was established April 8, 1908, to determine the amount 

of water available for irrigation in connection with the Strawberry 

Valley project of the United States Reclamation Service. It is 

located at the power plant in the mouth of the canyon, about 1| 

miles southeast of Payson, Utah.

Records during 1908 and part of 1909 were obtained from a rectangular weir above the tail race of the power plant. During the 

latter part of 1909 records were obtained-from a new weir below the 

tail race. Both weirs are rectangular, with 12-foot length of crest. 

As both these weirs are very poorly constructed and the records 

are very unsatisfactory, no reliable estimates of daily discharge can 

yet be made.

THE GREAT BASIN. 89 

SEVIER RIVER BASIN. 

DESCRIPTION.

Sevier Kiver is formed by the junction of South and East forks, 

which rise in Garfield and Kane counties in southern Utah and meet 

near Junction. The river flows northeastward to a point near Gunnison, northwestward nearly to Leamington, and then turns sharply 

to the southwest and discharges into Sevier Lake. It is more than 

200 miles long, measured by general course, and drains an area of 

about 5,000 square miles above the lower end of Sevier Valley.

The river occupies a long, narrow basin and receives few tributaries, San Pitch Kiver and Salina Creek being the most important. 

Salina Creek, which enters about 15 miles above Gunnison, is characterized by rapid run-off and during flood season carries an immense 

amount of sediment.

The San Pitch joins the Sevier near Gunnison below the gaging 

station on the main stream. Its flow is controlled By a storage 

reservoir about 15 miles above the mouth and is used for irrigating 

small tracts along the river. Manti Creek, its principal tributary, 

which enters above the reservoir, drains a barren area and has a 

rapid run-off.

Considerable irrigation is practiced from the Sevier above Gunnison, and the flow is controlled by a few small storage reservoirs.

The wettest year in the basin since 1900 was 1907 and the driest 

was 1902, the ratios of discharge for the two years being about 11 to 1.

The following gaging stations have been maintained in this basin:

Sevier River near Marysvale, Utah, 1906-1909. 

- Sevier River near Gunnison, Utah, 1900-1909. 

Sevier River near Leamington, Utah, 1889-1893. 

Salina Creek near Salina, Utah, 1900. 

San Pitch River near Gunnison, Utah, 1900-1905. 

Manti Creek near Manti, Utah, 1900.

SEVIER RIVER NEAR MARYSVALE, UTAH.

This station, which was established February 18, 1906, to determine the amount of water available for irrigation and storage in the 

upper valley of Sevier Kiver, is located about 6 miles above Marysvale, Utah, about 3 miles below the site of the proposed state dam 

on Sevier River, and about 10 miles below the junction, of South and 

East forks. The equipment consists of a cable and car and a vertical 

staff gage, which has remained unchanged since the station was 

established.

During very cold weather the records are somewhat affected by 

ice. The flow is not affected by artificial control below, but the 

daily flow depends to some extent on manipulations of gates at 

storage reservoirs on the South and East forks. The bed of the 

stream is somewhat shifting, but the results may be considered good.

SEVIER RIVER NEAR GUNNISON, UTAH.

This station, which was established June 29, 1900, to determine 

the amount of water available for irrigation at this point, is located 

at the highway bridge on the road to Westview precinct, about 4 

miles west of Gunnison, Utah.

It is about three-fourths of a mile above the mouth of San Pitch 

River and below all other important tributaries.

Measurements are made from the bridge or by wading. An 

inclined staff gage is located just below the bridge, the datum of 

which has remained unchanged since the station was established.

The records are occasionally slightly affected by ice and the bed of 

the stream shifts somewhat during floods, but on the whole the 

records may be considered good.

BEAVER RIVER BASIN. 

DESCRIPTION.

Beaver River with, its tributaries, North, South, and Indian creeks, 

rises on the western slope of the Tushar Mountains, in the southwestern part of Utah, and flows in a westerly direction to Minersville, 

thence northerly until its waters are lost in the sands.

The upper portion of the drainage area is rough and mountainous, 

some of the peaks rising to elevations of over 12,000 feet, and the 

flow in this portion of the basin is regulated both by snow and by 

the nature of the soil which absorbs and holds back the moisture. 

The lower portion of the drainage area consists of a high dry plateau, 

most of which is desert.

Beaver River is nominally a part of the Sevier Lake drainage, but 

a few miles north of Milford it becomes intermittent in flow and only 

a small portion of the highest floods ever reaches the lake.
94 SURFACE WATER SUPPLY, 1909 PART X.

The following stations have been maintained in this basin:

Beaver River near Beaver, Utah, 1906. 

Minersville Canal at Minersville, Utah, 1906. 

North Fork of North Creek near Beaver, Utah, 1906. 

South Fork of North Creek near Beaver, Utah, 1906. 

South Creek near Beaver, Utah, 1906. 

Indian Creek near Beaver, Utah, 1906. 

Beaver River near Minersville, Utah, 1909.

BEAVER RIVER AT MINERSVILLE, UTAH.

This station, which was established April 13, 1909, to determine 

the amount of unappropriated water available for irrigation at this 

point, is located about one-half mile below the Beaver County bridge 

and about three-fourths of a mile northwest of Minersville, Utah.

The station is below all tributaries, Indian Creek, North Creek, 

and South Creek entering 10, 12, and 15 miles, respectively, above 

the station. The Minersville Canal diverts all the normal low-water 

flow at a point about 2 miles above the station, at which the river is 

usually dry during several months in the summer.

Measurements are made from a footbridge, built for the purpose. 

An inclined staff gage is located just above the bridge. The gage 

datum has remained unchanged since the station was established.

The records are not affected by ice nor by artificial control below. 

The section is fairly permanent and the records may be considered 

good.

HUMBOLDT SINK DRAINAGE BASIN.

HTJMBOLDT BIVEB. 

DESCRIPTION.

Humboldt River rises in the northeastern part of Nevada and flows 

west and southwest a distance of about 350 miles into Humboldt Lake 

or Sink, in the western part of the State. The entire basin is surrounded by high and rugged peaks, some of which attain elevations 

of 11,000 feet above sea. A dam built a few years ago prevents the 

overflow in flood season from reaching Carson Sink, about 30 miles to 

the west.

The river is anomalous among the streams of the Great Basin in 

that both its source and its terminus are well within the area of interior drainage. Its valley is narrow, and its course and that of its 

tributaries lie in general through a barren region destitute of large 

trees and supporting few shrubs except scattered clusters of willows. 

The valley of the main stream affords the only east and west pass 

through the mountains of Neyada, and is followed by the Southern 

Pacific Railroad.

During the early spring and summer months the run-off of the North 

and South forks is very heavy because of the melting of the snows at 

the headwaters; as soon as the snow is all gone the rivers are left 

without a source of supply and their channels gradually become dry.

Several tributaries find their way into the main river, Rock Creek 

and Reese River entering near Battle Mountain, the North and South 

forks near Elko, and the Little Humboldt near Winnemucca.

Although opportunities for reclamation are many, the cost of the 

necessary work would be very great owing to the engineering difficulties to be overcome. The basin affords several reservoir sites 

where the flood waters could be collected and stored for use during 

the summer months.
THE GEEAT BASIN. 97

Lovelock Valley is considered the most fertile valley in the basin, 

and the entire flow of the river is appropriated for irrigation.

Alfalfa and grass hay are the chief crops; the land is best adapted 

for grazing.

The availability of the stream for power development is small, 

owing to the slight fall. Possibly the best stream for this purpose is 

the South Fork.

Within the period for which records are available the wettest year 

was 1907 and the driest year 1905.

The following stations have been maintained in this basin:

Humboldt River near Elko, Nev., 1895-1902.

Humboldt River at Palisade, Nev., 1902-1906.

Humboldt River at Battle Mountain, Nev., 1896-1897.

Humboldt River near Golcbnda, Nev., 1894-1909.

Humboldt River near Oreana, Nev., 1896-1909.

Marys River near Deeth, Nev., 1902-1903.

North Fork of Humboldt River near Peko, Nev., 1898-1900.

North Fork of Humboldt River near Halleck, Nev., 1902-1909.

South Fork of Humboldt River near Elko, Nev., 1896-1909.

Pine Creek near Palisade, Nev., 1902-1904.

Rock Creek near Battle Mountain, Nev., 1896.

HUMBOLDT RIVER NEAR GOLCONDA, NEV.

This station, which was established October 24, 1894, to determine 

the quantity of water available for irrigation in the vicinity of Golconda and Winnemucca, is located at the highway bridge 1^ miles 

north of the town of Golconda. It was discontinued December 31, 

1909.

The station is below the central valley, below Reese River and 

Rock and Keely creeks, and above all other important tributaries 

except Little Humboldt River, which enters about 12 miles below. 

Considerable water is diverted above the station, almost the entire 

low-water flow being used for irrigation.

The records are believed not to be materially affected by ice, but 

information as to winter conditions is meager.

Discharge measurements are made from the highway bridge or by 

wading.

During 1907 the staff gage was fastened to the bridge. The bridge 

and gage were washed out in December, 1907, and beginning January 

1, 1908, all readings have been taken from the original inclined staff 

gage on the left bank, reading 0.1 foot higher than the gage on the 

bridge.

As the channel is somewhat shifting the records are not of the best, 

but the station is nevertheless probably the most reliable on the 

Humboldt.

HUMBOLDT RIVER NEAR OREANA, NEV.

This station, which was established January 27, 1896, to determine 

the amount of water available for storage-reservoir sites in the 

vicinity of Humboldt station and also for the six canal systems now 

in operation below Oreana, is located near Oreana, Nev., about 

12 miles northeast of Lovelock and below all tributaries. The station 

was discontinued December 31, 1909.
100 SURFACE WATER SUPPLY, 1909 PART X.

Discharge measurements are made by means of a cable and car 

or by wading. Several staff gages have been in use at this station. 

The datum of the present gage has remained unchanged since 1904.

The channel is very unstable and sufficient measurements have 

not been made to give results that are entirely satisfactory or reliable. The gage heights are affected by ice during severe weather.

NOTE. The discharges from January 1 to March 20 are based on a rating curve fairly well defined above 

70 second-feet. Results for January probably too large because of possible ice effects. Discharges March 21 

to June 14 were obtained by the indirect method for shifting chminels. Discharges June 15 to December 9 

are based on a rating curve well defined above 163 second-feet. December 10 to 31, discharge estimated 

because of ice conditions.

102 SURFACE WATEB SUPPLY, 1909 PABT X.

NOETH FOEK OF HUMBOLDT EIVEE NEAE HALLECK,0 NEV.

This station, which was established October 10, 1902, is located 

one-fourth mile above the mouth of North Fork, 2 miles west of 

Elburz station on the Southern Pacific Railroad, and about 6 miles 

west of Halleck, the nearest post-office. It was discontinued December 31, 1909. Records at this point show the total flow of the river.

Discharge measurements are made by means of a cable and car. 

A new gage was installed August 5, 1909, being set to read the same 

as the old gage.

The channel is somewhat shifting, and the results are therefore 

only approximate. The gage heights also seem to be "affected by 

backwater from the main Humboldt. The river freezes during the 

winter, but information as to ice conditions is very meager.

104 SURFACE WATER SUPPLY, 1909 PART X.

SOUTH FORK OF HUMBOLDT RIVER NEAR ELKO, NEV.

This station, which was established August 29, 1906, to determine 

the amount of water available for storage, is located about 12 miles 

southwest of Elko, Nev., 6 miles above the mouth of the river, and 

is above the proposed reservoir site of the United States Reclamation Service. The station was discontinued December 31, 1909. 

As the station is below all tributaries the records show the total 

run-off from the basin of the South Fork.

The river freezes during two or three months of the winter, the 

ice probably reaching a considerable thickness, but information as 

to winter conditions is very meager.

Discharge measurements are made by means of a cable and car, 

or by wading.

The gage was removed February 26, 1907, about 1,000 feet upstream; and gage heights since that time bear no determined relation to previous readings. The channel at the station is somewhat 

shifting. During 1909 the gage heights were affected by the raising 

of a diversion dam below. As sufficient measurements have not 

been made to indicate the full extent of these changes the published 

estimates of discharge are only approximate.

SIERRA NEVADA DRAINAGE AREA.

PRINCIPAL STREAMS.

The Sierra Nevada drainage area includes the western part of 

Nevada, the eastern part of California, and'a small part of southcentral Oregon. The principal rivers of the area are Truckee River, 

discharging into Pyramid and Winnemucca lakes; Walker River, 

flowing into Walker Lake; Carson River, emptying into Carson Sink; 

Susan River, which flows into Honey Lake; and Owens River, discharging into Owens Lake.

TRUCKEE RIVER BASIN. 

DESCRIPTION.

The Truckee River system comprises the main river and several 

minor tributaries, all having as their chief sources of supply small 

mountain lakes. Truckee River itself is the natural outlet of Lake 

Tahoe, a beautiful mountain lake, 193 square miles in area, lying at 

an elevation of more than 6,000 feet above sea, and noted as the 

largest body of fresh water in the United States at so high an altitude. 

Nearly three-fourths of the lake is in California and the rest is in 

Nevada.

Issuing from the northwest side of Lake Tahoe the Truckee flows 

almost due north to the town of Truckee, Cal., where it turns to the 

east. At Wadsworth, Nev., the river again turns north and discharges into Pyramid and Winnemucca lakes, saline bodies of water 

without outlets. From the lake to Verdi, Nev., a distance of 35 

miles, the country is heavily timbered with fir and pine; below Verdi 

barren wastes alternate with small and fertile valleys the Verdi
THE GREAT BASIN, 107

Valley, the Reno or Truckee Valley, and the Wadsworth Valley all 

of which have a rich, productive soil. The total length of the Truckee 

is about 110 miles and itsxtotal fall is about 2,350 feet.

Donner Creek, the natural outlet of Donner Lake, is the first 

important tributary of the Truckee, which it enters at the town of 

Truckee. Prosser Creek, the second tributary, and the natural outlet 

of several small lakes, enters about 5 miles northeast of Truckee, and 

Little Truckee River, the natural outlet of Webber and Independence 

lakes, comes in at Boca, Cal., about 2 miles farther along. Each of 

these tributaries rises at an elevation of 6,000 feet above sea level, and 

each flows from a lake whose capacity can be enlarged by building a 

dam across its outlet. The region about the lakes is thickly forested 

and receives during the winter months very heavy snowfall. During 

the season of thaw this snow affords an immense run-off, almost all 

of which could be stored by enlarging the natural lakes.

Three power plants have been installed on the Truckee the 

Farad (Mystic), Fleish, and Washoe plants with an emergency 

plant near Reno, Nev. The plants have an average capacity of about 

2,500 horsepower each and they supply practically all the power used 

by the towns of Verdi, Reno, Carson City, Yerington, Gardnerville, 

Sparks, and Virginia City, Nev. There are many falls on the headwaters of the small tributaries.

Almost all the minimum flow of the river is appropriated for irrigation, but further storage development would make more water available for both irrigation and power.

Within the period covered by the records, 1907 was by far the 

wettest year and 1900 the driest year. The ratio in the two years 

for the state-line station was about 3.4 to 1.

The following gaging stations have been maintained in the Truckee 

River basin:

Lake Tahoe at Tahoe, Cal., 1900-1909.

Truckee River at Tahoe, Cal., 1895, 1900-1909.

LAKE TAHOE AT TAHOE, CAL.

Records of the height of Lake Tahoe have been kept since 1900 

to determine the amount of water drawn from storage and the possibility of further regulation of the outflow. These records are now 

for the first time available for publication. All gage heights have 

been referred to a datum 6,220 feet above sea level, the gage now in 

use being set at that datum. The gage heights for 1907 and 1908 as 

given in Water-Supply Paper 250, page 102, refer to a datum 6,225.5 

feet above sea level.

From 1889 until early in 1904, the floor of the outlet gates of the 

dam had a mean elevation of 6,223.3 feet, and the crest of the spillway at its highest point was 6,229.3 feet. Since 1904 the mean elevation of the floor of the gates has been 6,223.08, that of the lowest 

gate 6,223.04, and that of the lowest part of the spillway has been 

6,229.50.

The following table summarizes the fluctuations of the lake for the 

past twenty-two years as far as they have been recorded:

114 SUEFACE WATER SUPPLY, 1909 PAET X.

TEUCKEE EIVER AT TAHOE, CAL.

This station, which is located at Tahoe, Cal., about one-fourth 

mile below the outlet of Lake Tahoe, was established June 17, 1900, 

to determine the total outflow of the lake and its value as a storage 

reservoir information needed by the United States Reclamation 

Service in connection with the Truckee-Carson project.

A timber dam across the river about 500 feet from the lake completely regulates the flow of the river, sometimes causing sudden 

fluctuations and often cutting down the outflow to 15 or 20 secondfeet, or the amount of leakage through the dam. The equipment 

consists of a cable and car and a vertical staff gage.

The channel is liable to shift only in a slight degree and records 

are reliable. The datum of the gage has not-been changed. The 

flow is practically unaffected by ice.

The following discharge measurement was made by L. J. Towne:

May 18, 1909: Width, 68 feet; area, 126 square feet; gage height, 1.40 feet; discharge, 134 second-feet.

Daily gage height, in feet, of Truckee River at Tahoe, Cal., for 1909.

TRUCKEE RIVER AT NEVADA-CALIFORNIA STATE LINE.

This station, which is located at the state line, 17 miles west of 

Reno, Nev., was established September 1, 1899, to determine the 

quantity of water available for use in the Reno or Truckee Valley.

The station is below all tributaries which have their headwaters in 

the Sierra Nevada divide, and is above all diversions,
116 SURFACE WATER SUPPLY, 1909 PAET X.

The gage was formerly located at Farad, 2^ miles above the 

measuring section. On June 14, 1909, the station was moved downstream 1\ miles to Calvada.

The equipment consists of a cable and car and an inclined staff 

gage located 50 feet downstream from the cable. Gage heights in 

the following table January 1 to June 30 are from the old gage; from 

July 1 to December 31 they are from the new gage.

The flow is probably unaffected by ice. The channel is somewhat 

shifting, requiring rerating after each high-water period. Flood 

measurements are made with difficulty, owing to the high velocities 

of the current. Records are fairly reliable.

TRUCKEE RIVER AT RENO, NEV.

This station, which is located in the city of Reno, about 12 miles 

below the California-Nevada line, near the upper end of Truckee 

Meadows, was established July 1, 1906, by the United States Weather
118 SURFACE WATER SUPPLY, 1909 PART X.

Bureau, in connection with its measurements of snowfall in the high 

Sierra, and gage heights have been furnished by that bureau.

The station is below all diversions for Truckee Valley, above any 

return waters, and below practically all tributaries except Steamboat 

Creek, which enters from the south a few miles below.

Discharge measurements are made from the Rock Street Bridge, 

about 800 feet downstream from the Virginia Street Bridge, where 

the vertical staff gage is located. Low-water measurements are 

made by wading. The datum of the staff gage is 4,481.60 feet above 

sea level and has remained unchanged. Measuring conditions are 

good, the stream bed is permanent, and the records are unaffected 

by ice and are considered good. (See fig 1.)

TRUCKEE RIVER AT DERBY DAM, NEV.

This station, which is located about 2 miles east of darks', Nev., 

three-fourths of a mile above the Reclamation Service diversion dam 

for the main canal of the Truckee-Carson project (see PI. V), was 

established July 1, 1907, to determine the amount of water available 

for the canal and the amount in excess of the requirements of the 

water users in the Wadsworth Valley.

The equipment consists of a cable and car and an inclined staff 

gage in two sections, the datum of which has remained unchanged. 

This station replaces the station at Vista, giving practically the 

same record.

Results obtained at this station are good, although at times gage 

heights are evidently affected by backwater?

DONNER CREEK NEAR TRUCKEE, CAL.

Donner Creek flows from the east end of Donner Lake eastward 

into Truckee River about 1| miles above Truckee, Cal., its length 

being about 2 miles.

The gaging station, which was established October 23, 1902, to 

determine the amount of water available for storage in Donner Lake 

for use on the Truckee-Carson project, is located 150 feet below the 

dam of the Donner Creek Ice Company and 1 \ miles west of Truckee, 

Cal., and below the mouth of Cold Creek, the principal tributary.

Discharge measurements are made from a cable and car. Four 

different gages were used during 1909. Previous to June 1 all gage 

heights are referred to the datum of the old gage. Beginning June 1 

they refer to a permanent inclined gage installed September 12, 1909, 

about 40 feet downstream from the old gage.

The record is considered reliable. It is probably not greatly 

affected by ice, but it is affected by the raising and lowering of the 

gates of the storage dam at the outlet of Donner Lake.

NOTE. The discharges from January 1 to June 1 are based on a well-defined rating curve. The same 

rating curve is applicable for December 2 to 31 if the gage heights to the rating curve are first reduced 1.6 

feet, corresponding to the difference in datums of the two gages. Discharges June 2 to December 1 are 

based on a rating curve well defined between 31 and 345 second-feet.

PROSSER CREEK NEAR HOBART MILLS, OAL.

This station, which is located just below Alder Creek, about 2 

miles above the mouth of Prosser Creek, 4 miles north of Truckee, 

and 3 miles below Hobart Mills, Cal., was established June 27, 1903, 

to determine the amount of water available for storage near the 

headwaters of the stream. It was discontinued October 15, 1904, 

and reestablished September 23, 1907, some miscellaneous measurements having been made at this point in the meantime.

Measurements are made from a wagon bridge or by means of a 

car and cable. The present gage is painted on the northeast iron 

pier of the bridge, and has been used since January 15, 1909.

The section is permanent between floods, but results are sometimes affected by ice conditions. Estimates for 1907-8 have been 

recomputed on the basis of data more recently available. Gage 

heights for 1907-8 are given in Water-Supply Paper 250, page 116.

LITTLE TRUCKEE EIYER AT STARR, CAL.

Little Truckee River rises on the eastern slope of the Sierra Nevada, 

in northwestern Nevada County, Cal., flows north, then east, and 

then south, and unites with the Truckee at the town of Boca, Cal.

The station was established June 25, 1903, to obtain data for the 

United States Reclamation Service as to the quantity of water available for storage at Independence and Webber lakes and along the 

course of the stream, and also for power development. It was originally located at Bruhn's mill, or Pine station, on the Boca and Loyalton Railroad. On January 1, 1908, it was moved 2 miles upstream 

to Starr, Cal., which is about 5 miles north of Boca, the nearest 

post-office. The flow is practically the same at both places. The 

station is below all tributaries except Dry Creek.
132 SURFACE WATER SUPPLY, 1909 PART X.

Discharge measurements are made from a cable and car. A new 

inclined gage was established August 3, 1909, with a datum 1 foot 

lower than the original gage. All 1909 gage heights refer to the new 

gage.

Kesults at Pine station have been poor on account of shifting 

channel, but the station at Starr promises to give good results. The 

creek freezes during parts of the winter.

134 SURFACE WATEE SUPPLY, 1909 PART X.

INDEPENDENCE CREEK BELOW INDEPENDENCE LAKE, CAL.

Independence Creek flows northeastward into Little Truckee 

River from the east end of Independence Lake, which lies near the 

crest of the Sierra Nevada at an elevation of nearly 7,000 feet and 

has an area of 709 acres.

The gaging station was established October 24, 1902, about oneeighth mile below the lake, in order to determine the amount of 

water available for storage. The records are also of interest as 

showing the run-off of a small area near the mountain crest. The 

station was discontinued June 30, 1907; records for 1907 were 

omitted from Water-Supply Paper 250 through an oversight.

Discharge measurements were made from a cable and car, or by 

wading. Two vertical staff gages were used; one 200 feet upstream 

from the cable was used .until July 1, 1904, when a new gage was 

installed about 75 feet below the lake outlet, both gages reading the 

same. Measuring conditions were good; the stream bed shifted 

somewhat, due to the filling in of sand, but the records as a whole 

are good, except those for 1906 and 1907, which are somewhat uncertain on account of lack of sufficient measurements. The discharge 

is controlled by the dam at the lower end of the lake. The monthly 

discharges for the entire period of records have been recomputed and 

are given below:

« Discharges for July to December have been estimated as 14 per cent of Little Truekee River at Starr 

station, this being a mean ratio derived from comparison of records; results are approximate.

NOTE. These discharges are based on rating curves covering the following periods: October 24, 1902, 

to May 15, 1903; May 16 to August 22, 1903; August 27, 1903, to May 25, 1904; May 26, 1904, to July 8, 1905; 

July 9 to September 30, 1905; October 1, 1905, to June 30, 1907. All are fairly well denned between 0.5 and 

130 second-feet except the last, which is not well defined for 1907.
THE GREAT BASIN. 137

CARSON RIVER BASIN. 

DESCRIPTION.

The Carson Kiver basin includes the area lying south of Lake 

Tahoe and between the Walker and Truckee river basins. Carson 

River is formed by its West and East forks, which rise in the 

extreme eastern part of California in a rugged and mountainous 

country heavily timbered with fir and pine, and flow northeastward 

to their union near the town of Gardnerville, Nev. From this point 

the river flows northward to Carson City, thence eastward through a 

rough and barren chain of hills and valleys, and finally discharges 

into the Carson Sink. The river is about 120 miles long, falling in 

this distance about 1,900 feet.

The water of the Carson is derived entirely from the snowfall and 

run-off from the high mountains. The basin contains no lakes, but 

many ideal reservoir sites are available near the headwaters and 

along the main river. These sites have been thoroughly investigated by the United States Reclamation Service and others interested.

Several fertile valleys lie along the course of this river and much 

land is unutilized for lack of water.

The minimum flow is all appropriated and the distribution of the 

water each year is the cause of much dissatisfaction. During the early 

spring and summer months the river is a raging torrent, but in the 

later summer the discharge is barely sufficient to supply the irrigation 

demand. By building reservoirs in the mountains this condition 

could be greatly improved and the waters of the two forks so controlled that the average daily flow would be greatly increased.

Good power sites are available along both forks of the river, but 

are at present wholly undeveloped.

Within the period for which records are available the wettest year 

was 1907 and the driest year 1905. The rate of run-off in these two 

years was three to one.

The following is a list of the stations maintained in the Carson 

River basin:

East Fork of Carson River at Rodenbah's ranch, near Gardnerville, Nev.,

1900-1907.

East Fork of Carson River at Horseshoe Bend, near Gardnerville, Nev., 1908-9. 

Carson River near Empire, Nev., 1900-1909. 

Carson River near Hazen, Nev., 1908-9. 

West Fork of Carson River at Woodfords, Cal., 1900-1909.
138 SUEFACE WATER SUPPLY, 1909 PART X.

EAST FORK OF CARSON RIVER NEAR GARDNERVILLE, NEV.

This station, which was established October 17,1900, at Rodenbah's 

ranch, about 5 miles southeast of Gardnerville, proved unsatisfactory, 

and on March 27, 19087 a new station was established at a place 

known as Horseshoe Bend, about 9 miles south of Gardnerville and 

3 miles above the old station. This point is below all tributaries and 

above all diversions. Measuring conditions are favorable, the section 

is permanent, and results are good.

The equipment consists of a car and cable and an inclined staff 

gage.

140 SURFACE WATER SUPPLY, 1909 PART X.

CARSON RIVER AND BRUNSWICK MILL POWER CANAL NEAR EMPIRE, NEV.

This station, which was established October 21, 1900, was originally 

located three-fourths of a mile east of Brunswick Mill and 2^ miJes 

east of Empire, Nev. This gage was washed out by a flood March 

19, 1907. On April 12, 1907, a new gage was installed on the crest 

of the diversion dam of the Brunswick Mill canal, \\ miles below 

Empire and 6 miles east of Carson City, Nev. Only one measurement 

was referred to this gage, and elevation of the gage datum was not 

referred to the crest of the dam, therefore no discharges can be computed from this time until June 7, 1907, when a new gage was installed 

on the county bridge at Brunswick Mill, 500 feet below. All gage 

heights since that time refer to the same datum. Discharge measurements are made from a car and cable located just above the highway 

bridge. An inclined gage is located under the bridge. The power 

canal of the mill has diverted water past the gage on the river since 

April 12, 1907, so its discharge must be added to give the total. As 

records have been kept on the canal only since April 13, 1908, the 

total flow of the river prior to that time can be estimated only approximately. The power is now used to pump water for irrigation, 

although formerly it was used to run a stamp mill. The station on 

the canal is at a bridge crossing the canal directly opposite the cable 

in the river.

The records at this point show the discharge of the river below the 

Gardnerville Valley and above the Dayton Valley, and are of value 

to the United States Reclamation Service in connection with the 

Truckee-Carson project and to the state engineer of Nevada in the 

adjustment of water rights.

Good results have been obtained on the river, but the gage in the 

canal is within the influence of backwater from the mill and is not 

always an index of the discharge. Discharges for the canal are 

therefore only approximate. Ice interferes with records at times 

during the winter.

144 SURFACE WATER SUPPLY, 1909 PART X.

CARSON RIVER NEAR HAZEN, NEV.

This station, which is located about 8 miles south of Hazen and 

above Truckee canal chute, was established January 12, 1908, to 

determine the amount of water from Carson River available for 

storage in connection with the Truckee-Carson project of the United 

States Reclamation Service. A reservoir of about 100,000 acre-feet 

capacity will be erected at this point to conserve the flood waters of 

the Carson and also the water delivered by the Truckee canal.

To avoid the effect of backwater from the canal chute the gage 

was moved upstream on April 28, 1908. Gage heights prior to that 

time are of no value. Discharge measurements are made by wading 

and from the cable, which is about 1,500 feet upstream from the 

chute at the end of the canal. An inclined gage is located on the left 

bank just below the cable.

The plotting of the discharge measurements indicates some shift 

in the channel. Well-defined ratings for 1908 and 1909 have been 

developed, however. The 1908 gage heights are given in WaterSupply Paper 250, page 128.

NOTE. The daily discharges from April 28,1908, to January 15,1909, are based on a rating curve that is 

fairly well defined above 73 second-feet. From January 16 to December 31 discharges are based on a rating 

curve well defined between 17 and 3,000 second-feet. The river was dry or water standing in pools August 

1 to October 4, 1908. Discharges November 25-December 1 and December 11-31, 1908, estimated.

effect during portions of January and December, 1909, and that the means as computed for these months 

are too great.
THE GREAT BASIN. 147

WEST FORK OF CAESON RIVER AT WOODFORDS, CAL.

West Fork of Carson River in Alpine County, Cal., flows in a 

general northerly direction and unites with East Fork in Douglas 

County, Nev.

The gaging station, which is located about three-fourths mile 

above the post-office at Woodfords, Cal., and 200 feet from the main 

road between Woodfords and Blue Lake, was established October 

18, 1900, to determine the flow of the stream available for storage. 

On May 18, 1907, the gage and bench mark were washed out, and 

on June 8 the gage was reestablished at the same location at a different datum.

The stream bed is permanent, but is very uneven and the current 

is very rough. The measurements prior to 1907, though scattering, give a fairly well-defined curve. A fairly well-defined rating, 

applicable since June. 8, 1907, has been developed. The extent of 

ice conditions during the winter is not definitely known.

HONEY LAKE BASIN.*

Honey Lake occupies a shallow depression in Honey Lake valley, 

in the southeastern part of Lassen County, Cal. It may be classed 

as a playa lake, as it is without outlet and becomes completely desiccated during seasons of unusual aridity. It is supplied principally 

by Susan River, which enters it from the northwest, but it receives 

also some tribute during the rainy season from Long Valley. The 

hot springs along its northern border also furnish considerable quantities of water. The area of the lal^e varies with the seasons as well 

as from year to year, as is common with all inclosed lakes. Its outline is indefinite, as its shores are usually low and marshy and in

places form broad tule swamps. Its waters are quite strongly 

alkaline, unfit for human use, and are always of a greenish-yellow 

color, due to the impalpable mud held in suspension.

The following stations have been maintained in Susan River basin:

Susan River near Susanville, Cal., 1900-1905. 

Willow Creek at Merrillville, Cal., 190^-1905. 

Willow Creek near Standish, Cal., 1900-1905.

The results of measurements at these stations were published in 

Water-Supply Paper 177, pages 42-49.

MONO LAKE BASIN."

Lake Mono is situated in east-central California, within a few miles 

of the California-Nevada boundary. The thirty-eighth parallel and 

the one hundred and nineteenth meridian intersect in the center of 

the lake. It lies at the eastern base of the Sierra Nevada, and its 

drainage area forms one of the many independent hydrographic 

basins into which the vast region included between the Rocky Mountains and the Sierra Nevada, known as the Great Basin, is divided. 

The western rim of its drainage area, formed by the crest line of the 

Sierra Nevada, coincides for 36 miles with the western margin of 

the Great Basin.

Situated at the junction of two well-defined and strongly contrasted geographic provinces, the Mono basin partakes of leading 

characteristics of each. It is remarkable for its diversity of topography, its varied and striking contrasts of scenery, its wide range of 

climate, and corresponding variations of flora.

Lake Mono is 6,380 feet above the sea. The lowest pass in the 

serrate mountain crest along its western border is 3,000 feet above 

its surface. The highest peaks that overshadow it rise more than 

6,000 feet above the level of the lake. The eastern portion of the 

basin partakes of the character of the arid region of interior drainage 

of which it forms a part, and includes valleys covered with sagebrush 

and rugged mountain slopes, which are but scantly clothed with 

cedar and pifion. The tone of the landscape in this portion of the 

basin is gray and russet-brown, characteristic of the desert. Over 

its entire area no running water can be found during the greater part 

of the year, and the region is consequently silent and lifeless. To 

one reared under more humid skies this portion of the Mono basin 

would appear a veritable desert, but that it is not really a*ttesert is 

shown by the fact that it produces nutritious bunch grass among the 

clumps of sagebrush in sufficient abundance to afford pasturage for 

a few cattle and horses.

The southwestern border of the basin includes magnificent mountains, that are clothed in favored places with forests of pine. The

highest peaks reach far above the timber line and bear a varied and 

beautiful alpine flora. In the canyons" that descend from the snow 

fields and miniature glaciers about the higher summits the rush of 

creeks and rills is heard throughout the year. The eastern and western portions of this single hydrographic basin are fragments of two 

distinct geographic provinces. One has the desolation and solitude 

of the Sahara, the other the rugged grandeur of the Pyrenees.

The lake derives the principal portion of its water supply from the 

creeks that descend the eastern slope of the Sierra and empty into 

it from the south and west. Supplementing the surface drainage are 

a number of springs, some of which are of considerable size.

The creeks tributary to Lake Mono are of clear, pellucid water, and 

flow through channels excavated for the most part in granite and 

metamorphosed sediments, but near their mouths they have eroded 

small gorges through lacustral marls and volcanic lapilli deposited 

during previous high-water stages of the lake. No chemical analyses 

of these waters have been made, but they have, without question, 

the normal purity of mountain streams. We may be sure, however, 

that like other streams they hold a small percentage of mineral matter in solution, which is left when evaporation takes place.

None of the springs of the basin are highly charged with mineral 

matter, but, on the contrary, some of the more copious are remarkable for their purity.

With the exception of a very small spring on the road between 

the town of Aurora and the valley of the same name,, all springs of 

the basin are either in the bottom of the lake or quite near its shores, 

and they occur in greatest abundance near the base of the mountains. 

Only three of those that rise on the land have a temperature noticeably above the normal. The character of most of those rising in the 

bottom of the lake is uncertain. In some instances they reveal their 

presence in cold weather by the vapor to be seen on the lake surface 

above them, and are thus known to be thermal.

No gaging stations have been maintained on streams tributary to 

Mono Lake, but a few miscellaneous measurements have been made. 

These are recorded in Water-Supply Paper 251.

OWENS RIVER BASIN.

The Owens River basin is situated in the eastern part of California 

in Mono and Inyo counties, east of the main crest of the Sierra, which 

for a distance of about 140 miles forms the watershed between it and 

the basin of San Joaquin, Kings, and Kern rivers. It is south of 

Mono Lake basin and north of the arid region separating it from the 

Mohave Desert at the south. Its eastern limit is determined by the 

White Mountains at the north and the Inyo Mountains at the south. 

The length of the basin is about 120 miles; its width is about 20
THE GREAT BASIN. 153

miles at the south and 30 miles at the north, and its total area, 

including Owens Lake, comprises approximately 2,800 square miles, 

of which about 1,100 square miles are east of the river.

Owens River rises among the high peaks of the Sierra, east of 

Mount Lyell and directly opposite the headwaters of San Joaquin 

River, at an altitude of nearly 12,000 feet above sea level. It flows 

eastward into Long Valley, thence southwest ward through Owens 

River canyon into Owens Valley, thence eastward and southward 

through the trough of the valley to Owens Lake, about 20 miles 

southeast of Mount Whitney and directly opposite the northern part 

of the Kern River basin. The total length of the river is about 125 

miles 45 miles above the lower end of the canyon and 80 miles in 

Owens Valley.

More than forty lateral streams, many of them, however, comparatively small, drain a part of the eastern slope of the Sierra and enter 

the main stream from the west. The principal tributaries, from 

north to south, are as follows: Rock, Pine, Horton, McGee, Birch, 

and Bishop creeks, opposite the San Joaquin basin; Coyote, Baker, 

Big Pine, Birch, Tinemaha, Taboose, Goodale, Division, Sawmill 

(Eightmile), Thibaut, Oak, Pine, and Symmes creeks, opposite Kings 

River basin; and Shepard, Bairs (Moffett), George, Hogback, Lone 

Pine, Tuttle, Richter,. Cottonwood, and Ash creeks, opposite Kern 

River basin. No drainage enters Owens River from the east except 

during exceptionally heavy rainstorms, which are rare.

The basin is long and comparatively narrow and its topography is 

varied. It comprises a rough east-side mountain slope 5 or 6 miles 

wide, a valley floor about 6 miles wide, and a west-side slope ranging 

from 6 to 10 miles or more in width. The west-side area is made up 

of a very rugged and precipitious mountain slope 4 or 5 miles wide, 

and a sloping alluvial plain composed of delta-fan surfaces ranging 

from 1 to 5 miles in width and lying at the foot of the mountains and 

west of the western margin of the valley. Owens Valley is smooth 

and ranges in altitude from 3,600 feet at the south end to about 4,100 

feet at the north end. The crest of the east-side range of mountains 

averages about 6,000 feet higher than the valley floor. The west-side 

plain consists of a porous granitic alluvium of considerable depth; 

and ranges in altitude from about 4,000 feet at the western valley 

margin to about 6,000 feet at the foot of the mountains. It has a 

fairly uniform slope of 400 to 600 feet to the mile. The eastern slope 

of the Sierra is very steep and rugged, and ranges in altitude from 

about 6,000 feet at the foot to 13,000 or 14,000 feet at the crest. The 

geologic formation is granitic.

The eastern slope of the basin is practically barren of vegetation, 

except for places of scanty desert growth. The western slope has a 

very slight soil covering and only a sparse timber growth, found
154 SURFACE WATER SUPPLY, 1909 PART X.

chiefly along the water courses. All the western slope, a large part of 

the eastern slope, and the central part of Owens Valley are included 

in national forests.

The mean annual precipitation in Owens River basin is very light, 

especially on the valley floor and the eastern slope. The only records 

available are for the valley and indicate that the mean annual precipitation there is about 5 inches. On the Sierra slope the precipitation probably increases with increase of latitude and certainly increases with increase of altitude. On the higher parts of the slope 

it is probably 30 or 40 inches and possibly more; and it occurs almost 

entirely as snow, whose melting feeds the numerous streams that 

issue from this slope. These streams usually have their minimum 

flow in February and their maximum in July. Their combined maximum is about ten times their combined minimum. There is about 

the same ratio of disparity in the monthly extremes of precipitation, 

but the seasons are reversed.

Owens Valley is extensively cultivated and particularly adapted to 

stock raising. Numerous diversions are made for irrigation at different points on Owens River and tributaries, particularly in the upper 

part of the valley. Considerable water is also used for irrigating 

meadow lands in Long Valley north of Owens River canyon, but it 

is returned to the river above the head of Owens Valley.

Many excellent reservoir sites exist on the main stream and on the 

upper reaches of its tributaries.

There are many opportunities for power development in this basin. 

The fall is so great and the minimum flow of the stream so large and 

reliably constant that many thousands of horsepower could be developed. It is estimated that a minimum of more than 100,000 horsepower could be obtained without storage, and this amount could be 

considerably more than doubled by utilizing all the possible storage. 

The Los Angeles aqueduct, when completed, will have a capacity of 

400 second-feet and a total fall of more than 3,000 feet from its intake 

in Owens Valley to its outfall in San Fernando Valley near the city 

and will generate more than 100,000 horsepower. A full development of all the power opportunities in Owens River basin would 

probably yield more than 300,000 horsepower continuously.

Considered as a source of water supply, Owens River basin has 

other features of special interest. Nearly all the streams rise in glacial lakelets and marshes which are located at high altitudes near the 

crest of the Sierra, and serve to a certain extent as storage reservoirs 

in regulating the flow. The streams emerge from the mouths of their 

canyons upon the porous alluvial plain at the base of the Sierra, which 

is 1 to 5 miles in width and several hundred feet deep and across 

which they flow to the Owens River channel in the trough of the valley. This belt of debris is the source of a large and important loss,
THE GEEAT BASIN. 155

part of which appears in numerous springs throughout the valley. 

Perhaps stronger evidence of the great loss by seepage is afforded by 

the broad belt of wet and somewhat boggy land which extends over 

a large part of the trough of the basin. Undoubtedly large quantities of water can be obtained by sinking wells within this area. Several artesian wells which have been sunk in the vicinity of Independence yield a strong flow and give convincing evidence of an artesian 

belt in the valley. With a view to the greatest ultimate utilization 

of the valley's water supply, the city of Los Angeles is conducting 

special investigations to determine the depth to and fluctuations in 

the ground-water plane and the rate of evaporation from free water 

surface and saturated gravels near Independence; also to determine 

the amount of precipitation on the alluvial plain at the base of the 

Sierra between the 4,000 and 6,000 feet contours and the seepage 

losses of creeks crossing it.

The longest run-off record in Owens River basin extends back to 

1903, when stations were established on the main stream and on 

Rock and Pine creeks near Round Valley, and Bishop Creek near 

Bishop. The wettest year since that time was 1906 or 1907 and the 

driest 1905. The total flow during the wettest year was nearly 

double that during the driest.

The following gaging stations have been maintained in this basin:

Owens River near Round Valley, 1903-1909.

Owens River near Tinemaha, 1906-1909.

The results of stream measurements at these stations for 1909 are 

published in Water-Supply Paper 271.
156 SURFACE WATER SUPPLY., 1909 PART X.

In the fall of 1903 stations were established on five or six of the 

principal streams in Owens Valley and on numerous diversion canals 

used for irrigation. These stations were maintained two or three 

years to obtain general statistical data on the water supply of Owens 

Talley, and also for the purpose of determining the quantity^! 

water used for irrigation at that time and the suitability of the valley 

for a reclamation project. After the city of Los Angeles had acquired 

its extensive holdings in the valley and had taken active steps to 

utilize the flow of Owens River and tributaries for a municipal water 

supply, many other stations were established at the request of and 

in cooperation with the city. Since that time all stations in Owens 

Valley have been maintained in cooperation with the city of Los 

Angeles, the city paying all field and maintenance expenses and the 

National Government furnishing and paying an engineer to do the 

work.

All stations in Owens Valley, except those on Owens River, are 

located near the western margin of the valley, and most of them are 

below the delta fans which extend eastward from the mouths of the 

canyons and are above all diversions. Almost without exception 

measurements are made from footbridges or by wading. The current is swift at almost every station and the channel is subject to 

more or less change.

GREAT BASIN DRAINAGE IN OREGON. 

DESCRIPTION.

In Oregon, as in other portions of the Great Basin, the surface 

waters collect in natural depressions in the ground. Where the flow 

into these depressions is sufficient perennial lakes are formed of such 

extent that the inflow balances evaporation; where the surface flow 

is insufficient, intermittent lakes or play as are formed. The principal lakes in Oregon are Harney, Malheur, Warner, Summer, Silver, 

Goose, and Abert. With the exception of Silver Lake in Lake County 

the waters of all these lakes are more or less alkaline.

MALHEUR AND HARNEY LAKES DRAINAGE BASIN.

DESCRIPTION.

Malheur and Harney lakes, which are in Harney County, occupy 

a large basin having a general elevation of 4,100 feet and rimmed by 

mountain ranges whose elevation is between 5,000 and 7,000 feet. 

They are connected by a small strait known as The Narrows, through 

which the water of Malheur flows into Harney Lake. For this reason 

the water of Malheur Lake is practically fresh while that of Harney 

Lake is alkaline. The average rainfall in the basin is about 10
THE GREAT BASIN. 157

inches; on the summit of the divide it is probably about 18 inchesjor 

more.

The agricultural lands in this basin comprise nearly 700,000 acres 

of flat alluvial soil forming a circular valley surrounding the lakes 

and extending like fingers into the valleys of tributary streams.

The lower lands are more or less swampy and have for years been 

utilized as hay flats. During the spring months, when water is 

abundant, small rock-and-brush dams sufficiently high to cause the 

streams to overflow their banks are constructed at convenient points. 

Much of the meadow lands may thus be covered by a foot or more of 

running water during five or six weeks of the season. As the stream 

flow diminishes the swamp and hay lands gradually drain until the 

middle of July, when they are sufficiently dry to permit the cutting 

of hay.

Comparatively small areas are cultivated, and on .these the crops 

are limited to rye, oats, and barley. The principal industry of the 

region has been stock raising, and this has afforded a ready market 

for all grain and hay that could be raised. During recent years, however, much of the hay lands have been taken as homesteads and the 

better lands are rapidly being developed.

The principal streams in this basin are Donner und Blitzen River, 

from the south, and Silvies River, from the north, flowing into Malheur Lake; and Silver Creek, flowing from the northwest into Harney 

Lake. South of Silver Creek in a flat valley lies Silver Lake, a small 

playa which is supplied by overflow from Silver Creek. Donner und 

Blitzen River, with its principal tributaries Keiger, McCoy, and Mud 

creeks, drain the western slope of Steins Mountain. This mountain, 

which is the most prominent topographic feature in the area, is a 

long timberless ridge, extending northeast and southwest, with a 

crest length of 60 miles or more. The eastern slope forms an abrupt 

escarpment; the western slope, which forms a gradual ascent is 

deeply cut by canyons into which enormous quantities of snow are 

drifted each year, thus serving as efficient storage reservoirs for 

winter precipitation. The snows melt gradually and the flow of the 

streams draining the western slope of the mountain is therefore 

well maintained throughout the year.

Silvies River drains the northern part of the Malheur-Harney basin, 

rising in the heart of the Blue Mountains, flowing generally southward through a broken country to Harney Valley, which it traverses 

in a southeasterly direction, and emptying into swamp lands bordering the northern shores of Malheur Lake. A large part of its drainage 

area is heavily timbered. The stream is very "flashy," being subject 

to sudden floods which as suddenly subside. The summer flow is 

practically nothing.
158 SUEFACE WATEE SUPPLY, 1909 PAET X.

Silver Creek heads in a spur of the Blue Mountains and flows southeastward through Silver Creek valley into Harney Basin. The upper 

portion of its drainage area is well timbered, but the lower portion 

is bare. The stream is subject to sudden floods and in summer its 

flow practically ceases.

Between Silvies River and Silver Qreek and flowing in the same 

general direction is Sagehen Creek, a small stream heading in a spur 

of the Blue Mountains and draining a rough, broken country. It 

empties into the marsh surrounding the northern end of Malheur 

Lake near the point where. Silvies Rivers enters this marsh.

The eastern rim of Harney Valley is broken by a low pass known 

as Malheur Gap. Through this gap a drainage canal could be 

excavated that at the deepest portion would not require a cut of 

more than 18 or 20 feet. This canal would carry the waters of the 

lakes into Malheur River by way of a tributary of the South Fork. 

Such a project was at one time begun, but riparian owners of the 

lake border feared that the absence of these large bodies of water 

would have an unwholesome effect on the climate of the basin. 

Accordingly an injunction was issued restraining the company from 

building the project.

Gaging stations have been maintained in this basin as follows:

Silvies River near Silvies, Oreg., 1903-1905,1909.

Silvies River near Burns, Oreg., 1903-1906, 1908-9.

Donner und Blitzen River near Diamond, Oreg., 1909.

McCoy Creek near Diamond, Oreg., 1909.

Keiger Creek near Diamond, Oreg., 1909.

Silver Creek near Riley, Oreg., 1904-1906, 1908-9.

SILVIES EIVER NEAE SILVIES, OEEG.

This station, which is located at the proposed dam site about 3 

miles southwest of Silvies, Oreg., in sec. 14, T. 19 S., R. 31 E., was 

established June 16, 1903. Observations were suspended from 

December 31, 1904, to January 8, 1909, for lack of funds.

An inclined gage is located on the left bank under the cable. The 

right bank is a berm over which the water flows for 400 feet at an 

elevation of 5 feet on the gage. The cable spans the entire channel.

The results obtained at the station are valuable in connection with 

storage development. At the site of the station a dam can be constructed which will impound all the annual run-off from the drainage 

area above it. The water so stored could be diverted from the 

stream for the irrigation of lands in Harney Valley. This project 

was under investigation at one time by the United States Reclamation 

Service.
THE GREAT BASIN. 159

The conditions at the station are not favorable for highly accurate 

results, as it is impossible to establish a permanent rating curve. 

The banks of the stream are covered with heavy brush which serves 

to create unstable conditions to a certain extent. The bed is sandy, 

and some changes occur at flood times. During the winter months 

ice interferes materially with the determination of flow, but due 

allowance for such conditions has been made.

THE GREAT BASIF. 161

SILVIES RIVER NEAR BURNS, OREG.

This station was established August 14, 1903, but lack of funds 

caused suspension of observations from July 24, 1906, to December 11, 

1908. The gage is located at a wagon bridge near Barker's house, 10 

miles upstream from Burns. The cable from which gagings are made 

is at Lampshiire's ranch, 1 mile above the gage.

The conditions at the cable are not favorable for accurate measurements. The stream flows through' a flat, alluvial bottom. The 

banks are lined with a dense growth of willows and underbrush. The 

right bank is subject to overflow for about 600 feet. The left bank 

is high and will not overflow. A number of sloughs carry part of the 

water from Immigrant Creek around the gage and cable. On this 

account the discharge at the station is somewhat less than the actual 

run-off from the watershed.

The water of Silvies River is largely used for the flood irrigation 

of hay lands in Harney Valley. As even the flood discharge of the 

stream is used for this purpose, the development of an irrigation 

project that would contemplate the diversion of the water would 

involve the settlement of accrued water rights.

DONNER UND BLITZEN RIVER NEAR DIAMOND, OREG.

The waters of this stream are used for the irrigation of hay lands 

in the JDonner und Blitzen swamp, which extends from P ranch to 

Narrows and embraces nearly 100,000 acres of land. The ranch is 

owned by the William Hanley Company, who has furnished observations of gage heights voluntarily.

This station was established January 27, 1909, on the P ranch, 25 

miles southwest of Diamond.

Measurements were made from a private wagon bridge near the 

ranch buildings. A vertical staff gage is installed on thq right bank 

just below the bridge.

Five irrigation ditches divert water from the stream| above the 

bridge, and a brush and rock dam about 300 feet below t|he bridge is 

used to divert the water into another ditch. When water is to be 

diverted' the dams are repaired and raised by the addition of more 

rock and brush. The ditches are not closed until the fall.

The dam below the station has had an unstable influence on the 

gage heights.

The records represent considerably less than the natural flow of 

the stream, particularly during the irrigation season. The normal 

combined capacity of the five ditches is about 35 secondt-feet. Two 

of these ditches run water during the entire year; thijee of them 

during the irrigation season only. No record has been kjept of their 

actual time of operation.
164 SURFACE WATER SUPPLY, 1909 PAET X.

The station was moved on May 23, 1910, to the mouth of the 

canyon 2 miles above the bridge above all irrigation ditches. The 

banks of the stream, from a point near the mouth of the canyon 

5 miles above the P ranch to its mouth at Narrows, 30 miles below 

the P ranch, are subject to overflow during flood times. The immediate banks are covered with a dense growth of willows and underbrush. It is almost impossible to find a point where the stream can 

be measured in a single channel, even at moderate stages.

NOTE. These estimates represent considerably less than the natural flow of the stream, as no records 

were kept on the five ditches diverting water above the station.

CREEK NEAR DIAMOND, OREG.

This station was established January 27, 1909. It was first located 

three-fourths of a mile west of Diamond ranch house and 3 miles 

from Diamond post-office. Observations were suspended June 30, 

1909, because of the lack of an observer.
166 SURFACE WATER SUPPLY, 1909 PART X.

Several irrigation ditches divert water above the station for hay 

lands in the Diamond swamp, but no estimate has been made of the 

flow in these ditches, and the results obtained during 1909 do not represent the natural flow of the stream. The discharges, therefore, 

are only of general interest.

The course of the stream is through an alluvial bottom, and the 

banks are densely covered with willows and brush. The grade is 

light, and the branches of the trees trailing in the water form obstructions by catching drift and debris, which produce unstable gage 

heights. The results do not possess a high degree of accuracy.

The station was moved on May 23, 1910, to Kesterson's ranch, 2f 

miles above the old location and above all present irrigation ditches.

KEIGER CREEK NEAR DIAMOND, OREG.

The waters of Keiger Creek are used for the irrigation of hay land 

in the Diamond swamp.

The gaging station, which was established January 26, 1909, is 

located 3 miles south of Diamond post-office, and is above all present 

irrigation ditches.

The gage is a vertical staff on the right bank. Measurements are 

made by wading at any convenient point near the gage. No facilities have been provided for making measurements at high stages.

The stream flows through an alluvial bottom on a flat grade. The 

banks are subject to overflow and are densely grown with willows 

and underbrush. The treetops, trailing in the water, catch debris 

and form obstructions which produce unstable conditions at the gage. 

For this reason the results do not possess a high degree of accuracy, but 

they are sufficient for a general study of the behavior of the stream.

SILVER CREEK NEAR RILEY, OREG.

This station was established April 19, 1904. On account of insufficient funds observations were suspended from July 14, 1906, to 

January 14, 1909. On the latter date a cable was installed 200 feet 

above the bridges crossing Silver Creek on Cecil's ranch and about 12 

miles north of Kiley. These bridges are on the main stage road 

from Prineville to Burns.

One hundred feet below the cable is a brush and rock dam which 

diverts water into three channels. Stable relations between discharge 

and gage heights can be established only during the irrigating seasons 

and the time between first fall flood, when the dam is washed out, 

and the spring, when it is reconstructed. Usually only the brush, 

earth, and smaller stones are washed away. For this reason results 

at this station will be only approximate, but it is the only site that 

can be utilized that is within practicable distance of an observer.

When the station was reestablished January 14, 1909, it was practically impossible to install a permanent gage. Temporary gages 

have therefore been used, each being referenced to an iron post on 

the right bank 40 feet downstream from the gage. The elevation 

above gage datum is 11.80.

The waters of Silver Creek are now largely used for the irrigation 

of hay lands in Silver Creek valley. The Silver Creek reservoir site, 

which was investigated by the Reclamation Service, is 3 or 4 miles 

above the station. At this point a large quantity of water can be 

stored. Below the station on both sides of the stream are large areas 

of agricultural land which could be irrigated from stored water.

WARNER LAKE DRAINAGE BASIN. 

DESCRIPTION.

Wapner Lake includes a chain of lakes and marshes extending in a 

general north and south direction between two high escarpments in 

the southeastern portion of Lake County. The waters of these lakes 

flow from south to north, and the lakes in the southern end of the 

valley are therefore fresh while those at the northern end are alkaline. The larger lakes in the area from north to south are Crump 

Lake, Hart Lake, Flagstaff Lake, and Bluejoint Lake. The general 

elevation of the water surface is 4,550 feet.

Protected by- the high ridges that border it on both sides, this valley has reached a fairly high stage of agricultural development. At 

the base of the hills bordering the western shores of Hart and Crump 

lakes are a'number of prosperous ranches, whose products include 

fruit, grains, and nearly all agricultural crops.
170 SURFACE WATER SUPPLY, 1909 PART X.

The principal streams in this basin are Twentymile Creek, flowing 

from the south; Warner Creek, or Deep Creek, as it is locally called, 

flowing from the west; and Honey Creek, flowing from the west. 

These streams drain a high, practically timberless, ridge, but the flow 

of the streams is well maintained during the summer months. Warner Creek is the most important of these streams and Honey Creek 

is the next, though Twentymile Creek furnishes about the same 

amount of water as Honey Creek. All three are used more or less 

for irrigation, and any additional development will require construction of storage reservoirs on their headwaters.

Around the west side and north end of the valley is a large area of 

agricultural land, which is now growing sagebrush. The Warner 

Lake Irrigation Company has under way the irrigation of these 

lands by water stored on the headwaters of Warner and Honey 

creeks. The project is to be developed under the provision of the 

Carey Act.

Gaging stations have been maintained in this basin as follows:

Honey Creek at Plush, Oreg., 1909. 

Warner Creek at Adel, Oreg., 1909.

HONEY CHEEK AT PLUSH, OREG.

This station was established May 13, 1909, at a wagon bridge onefourth mile north of Plush. The gage first used was a vertical staff 

fastened to the bridge, but the gage heights were affected by temporary dams used below the station to divert water into irrigation 

ditches. On November 1, 1909, the gage was moved to the canyon, 

1 mile above the bridge, where its records should give a stable discharge curve. A cable was also installed at this point, from which 

discharge measurements can be made, except at extreme low water, 

at which time measurements are made by wading.

On Honey Creek are several favorable sites for the storage of 

water which can be used to irrigate lands lying to the north and west 

of Flagstaff and Bluejoint lakes. The Warner Lake Irrigation Company is investigating the feasibility of irrigating these lands under 

the provisions of the Carey Act, and the station was maintained in 

cooperation with this company.

Estimates of daily discharge for 1909 are withheld because of 

insufficient data and changing conditions of flow.

NOTE. Stream frozen over December 7. Ice conditions probably existed throughout the month. All

WARNER CREEK AT ADEL, OREG.

The station on Warner Creek (locally known as Deep Creek) was 

established May 11, 1909. Measurements are made from the county 

bridge 300 yards south of Adel post-office; the gage is located about 

200 feet upstream from the bridge and above a series of rapids.

Below the bridge the grade of the stream is very flat, and the water 

is diverted by means of a temporary dam, which is repaired at the 

beginning of each irrigation season. The gage, however, is out of 

the influence of this dam. Two ditches that head several miles 

above the gage divert water around it. The combined discharge of 

these ditches on May 18, 1910, was estimated at 12 second-feet.

Several reservoir sites are available on Warner Creek above the 

station where water could be stored for the irrigation of lands along 

the borders of the chain of lakes in Warner Valley.

No estimates of discharge are possible for 1909 on account of insufficient data and changing conditions of flow.

The station is maintained in cooperation with the Warner Lake 

Irrigation Company, which furnishes gage heights and has made some 

of the current-meter measurements.

ABERT LAKE DRAINAGE BASIN.

DESCRIPTION.

Abert Lake is a strongly alkaline body of water lying near the central part of Lake County. It has a surface area of 60 square miles at 

an elevation of 4,210 feet. The waters are largely supplied from 

Chewaucan River and Crooked Creek.

Chewaucan River rises on the high divide in the southern part of 

Lake County and flows northward into Chewaucan marsh, through 

which it meanders in a southeasterly direction and flows into Abert 

Lake at its southern extremity.

The principal agricultural development in the basin consists of the 

hay lands in the Chewaucan marsh and the area of irrigated lands
THE GREAT BASIN. 173

bordering the marsh on the south and along Chewaucan River in the 

vicinity of Paisley.

One gaging station has been maintained in this basin on Chewaucan 

River at Paisley, Oreg., 1905-1907, 1909.

CHEWAUCAN RIVER AT PAISLEY, OREG.

This station, which is located in the SE. J sec. 23, T. 33 S., R. 18 

E., one-fourth mile upstream from Paisley, was established January 4, 

1905. On account of insufficient funds observations were suspended 

from January 1, 1908, to January 17, 1909.

The gage is a vertical staff on the right bank 60 feet upstream from 

the cable, from which discharge measurements are made.

The left bank is high; the right bank is low and will overflow at 

high stages for a distance of 500 feet or more.

Near the station are several irrigation ditches. George Conn's 

ditch, which heads about 2% miles above the station, diverts water 

around the gage. Conn's mill ditch diverts water from the left bank 

250 feet below the gage, where a low timber dam has been constructed. 

This dam increases the gage heights artificially, but it is fairly permanent, and the accuracy of the records is not greatly affected by it. 

A short distance below Conn's mill ditch the Brattain ditch diverts 

water from the right bank. It follows the foothills for many miles 

down the river valley, and its water is used to irrigate land immediately around Paisley and large areas of hay land in Chewaucan 

marsh.

The waters of Chewaucan River at present are used forirrigation and 

for flooding hay lands in Chewaucan marsh. A segregation of 12,000 

acres northeast of Paisley has been made for reclamation under the 

terms of the Carey Act. It is proposed to store water for these lands 

at a point 20 miles upstream from Paisley. The development of this 

project, however, has been hindered by certain water-right claims of 

the owners of hay lands in Chewaucan marsh. Th6 general practice 

here has been to flood the lands during the spring and winter to a 

depth of several feet. As all the waters are claimed for this flooding 

no development work can proceed until the water rights have been 

settled. There is undoubtedly sufficient water for all interests if it is 

wisely used.

SUMMER LAKE; DRAINAGE BASIN.

DESCRIPTION.

Summer Lake is a strongly alkaline body of water with a surface 

area of about 70 square miles, at an elevation of 4,300 feet. The 

water is supplied largely from Ana River, a stream 7 miles long, 

which heads in five large springs on the northern border of the valley. 

These springs supply a continuous flow of about 145 second-feet. The 

water has a nearly constant temperature of 65°.

The agricultural development in this basin is limited to a narrow 

strip lying at the foot of a high escarpment along the western shore 

of Summer Lake. This narrow strip is the most favored section in 

central Oregon and in it intensive agriculture has been practiced 

since 1848. The escarpment is effective protection against the cold 

winds from the west and north, which in passing over make an eddy 

drawing the warm air of the lake over the lands and serving to equalize 

the temperature. The region has long been famous for its fruit. 

Apples, pears, peaches, cherries, and berries of all kinds are grown in 

abundance and failures are practically unknown.
THE GREAT BAS^N. 177

Along the eastern shore of the lake and extending eastward into 

the wide valley adjoining Chewaucan marsh is a large area of agricultural land, a portion of which could undoubtedly be watered from 

Ana River and another portion from Chewaucan River. Projects 

looking to the irrigation of these lands have been under consideration 

but nothing definite has yet been done.

The only gaging station maintained in this basin is the one on Ana 

River near Summer Lake, Oreg., 1905 and 1909.

ANA RIVER NEAR SUMMER LAKE, OREG.

This station, which was established March 28, 1905, is located near 

the head of Ana River, in the NW. J SE. J sec. 6, T. 30 S., R. 17 E., 

about 6 miles northwest of the town of Summer Lake, Oreg. No 

continuous observations of gage heights were obtained until January 

14, 1909. It was found, however, that the fluctuations in the gage 

heights were caused by temporary diversion dams in the stream about 

3 miles below the gage. Discharge measurements indicate that the 

flow is practically constant and equal to 145 second-feet. On this 

account observations of gage heights were suspended February 9, 

1910.

The waters of this stream are supplied from five large springs which 

lie along a fault line. The waters have a temperature throughout the 

year of 65° F. The water surface of the upper spring is 39.3 feet above 

normal water surface in Summer Lake; the water surface of the fifth 

or lower spring is 7.5 feet above that of Summer Lake. Below the 

second spring an attempt has been made to raise the water by an 

earth dam sufficiently high to divert it into a ditch for the irrigation 

of lands on the right, or south, side of the stream. This dam will raise 

the water 58 feet. The project is being developed by persons owning 

desert claims in the vicinity.

SILVER LAKE DBAINAGE BASIN. 

DESCRIPTION.

Silver Lake is a body of fresh water approximately 15 square miles 

in area, at an elevation of 4,340 feet. The western, southern, and 

eastern borders of the lake consist of high escarpments; to the northwest is Pauline marsh.

63150° WSP 270 11 12
178 SURFACE WATER SUPPLY, 1909 PART X.

Silver Creek, Bridge Creek, and Bear Creek flow from Yamsay and 

Hagar mountains northward into Pauline marsh and thence southeastward into Silver Lake.

The water surface in the lake fluctuates considerably. During a 

succession of high-water years the water rises sufficiently to overflow 

into Thorn Lake and cover a small portion of the desert to the east. 

This fact perhaps accounts for the freshness of the lake. After a succession of dry years the lake- surface diminishes and the waters become 

more and more alkaline, until freshened again by another overflow.

The principal agricultural development at the present consists of 

hay lands in Pauline marsh and small irrigated tracts bordering the 

streams. During recent years all land suitable for agriculture has 

been taken as homesteads, and dry farming has been practiced with 

more or less success.

To the northeast and practically connected with Summer Lake 

drainage basin is Christmas Lake Valley, a flat alluvial area comprising 300,000 acres. This valley has no surface streams, but contains two or three small lakes. Alkaline Flat, near the northeastern 

part of the valley,'is an intermittent lake; south of it Christmas Lake 

is a perennial body of water, at an elevation of 4,296 feet. North of 

Christmas Lake is Fossil Lake, and in the extreme southwestern portion and practically connected with Silver Lake basin is Thorn Lake. 

Nearly all the lands of Christmas Lake Valley have been taken as 

homesteads. Dry farming is practiced extensively and good crops of 

grain and potatoes and other crops have been raised. Water for 

domestic purposes is found in comparatively shallow wells. Near 

the eastern border of the valley, however, wells 40 feet in depth have 

encountered salt water.

Gaging stations in this basin have been maintained as follows:

Silver Creek near Silver Lake, Oreg., 1904-1907, 1909. 

Bridge Creek near Silver Lake, Oreg., 1905-6. 

Bear Creek near Silver Lake, Oreg., 1905-6, 1909.

SILVER CREEK NEAR SILVER LAKE, OREG.

This station was first established December 29, 1904. On March 

31, 1907, it was abandoned for lack of funds, but the observations 

were resumed on January 11, 1909. It is located 1| miles southwest 

of Silver Lake post-office, in sec. 28, T. 28 S., R. 14 E.

The bed and banks of the stream are fairly permanent. The gage 

is an inclined staff on the right bank near the cable from which discharge measurements ape made. The elevation of the gage has been 

verified from time to time by means of a bench mark near it at elevation 18.12. The gage has maintained its datum to the present time,
THE GREAT BASIN. 179

The results obtained at this station are of considerable value. The 

country through which the creek flows is more or less arid, and the 

natural summer flow of nearly all the streams is appropriated for 

present irrigation requirements. Any additional development will 

require storage. Several fairly good storage sites are available on 

Silver Creek, and below it lie areas of agricultural land that could 

easily be irrigated from stored waters.

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

records are believed to be reliable.

THE GREAT BASIN. 181

BEAR CREEK NEAR SILVER LAKE, OREG.

The station on Bear Creek (locally known as Buck Creek), was 

first established January 21, 1905. It was abandoned on July 21, 

1906, but observations were again resumed January 11, 1909. It is 

located 3 miles southwest of Silver Lake post-office, at the county 

highway bridge.

The conditions at this station are not favorable for good results. 

Above the station a diversion dam has been constructed, and below 

it several brush dams are put in each year for the purpose of diverting water in small ditches or for flooding hay lands. These artificial 

conditions affect the height of the water, creating back-water influence on the gage, and for this reason it has been impossible to make 

reliable estimates of discharge.

The results at the station are chiefly of local interest. The waters 

of the stream are appropriated during the summer months for irrigation, and there has been considerable litigation over them.

The following discharge measurement was made by R. B. Post:

April 28, 1909: Width, 34 feet; area, 83.4 square feet; gage height, 5.79 feet; discharge, 39.7 second-feet.

Daily gage height, in feet, of Bear Creek near Silver Lake, Oreg.,for 1909.

182 SURFACE WATEB SUPPLY, 1909 PAET X. 

GOOSE LAKE DRAINAGE BASIN. 

DESCRIPTION.

Goose Lake lies partly in Oregon and partly in California. It has 

a total surface area of 190 square miles at an elevation of 4,750 feet. 

The lower two-thirds of the lake surface is in California, but the 

greater portion of the agricultural lands bordering it are in Oregon, at 

its northern end and along both sides. Immediately along the northern edge of the lake are considerable areas of marsh hay lands, but 

farther north the valley is an unreclaimed sagebrush desert except for 

a few homesteads which have recently been taken.

The water of Goose Lake is slightly alkaline, though considerably 

less so than that of other lakes in the vicinity. This is accounted for 

by the fact that the lake has overflowed into Pit River in comparatively recent times, the last overflow having occurred about 1862. 

The lower end of the lake is also bordered by lava beds, through 

which some water may be lost by percolation.

Drews Creek, Cottonwood Creek, and Thomas Creek, the principal 

streams flowing into this basin, drain the southeast slope of a high 

timbered ridge near the southern corner of Lake County. The water 

of Drews Creek is at present being utilized by the Oregon Valley Land 

Company for the reclamation of 40,000 acres of land in the Goose 

Lake Valley. A storage reservoir of 60,000- acre-feet capacity is 

being constructed on Drews Creek about 5 miles above the mouth 

of the river canyon. From this reservoir an irrigation ditch has been 

constructed which carries water along the borders of the valley, both 

north and south of Drews Creek. A northern -branch wastes into 

Thomas Creek near the city of Lakeview. There is also a good storage 

site on Cottonwood Creek which undoubtedly will be utilized in the 

near future. The flow of Drews and Cottonwood creeks is well maintained throughout the year.

The following gaging station has been maintained in this basin: 

Cottonwood Creek, near Lakeview, Oreg., 1908-9.

COTTONWOOD CREEK NEAR LAKEVIEW. OREG.

This station was first established November 22, 1908, at a proposed 

site for a storage dam in sec. 29, T. 38 S., R. 19 E., and about 10 

miles west of Lakeview. On November 22 a trapezoidal weir was 

installed and a gage placed above it as an index to the head. The 

length of the weir was 10 feet. On January 19, 1909, the length of 

the weir was increased to 15 feet. During high stages there is considerable velocity of approach, and corrections therefor have been 

made.
THE GBEAf BASIN.

On January 19 a footbridge was installed about 1,000 feet below 

the weir. An inclined gage was set on the left bank, and measurements were made by current meter from the bridge, as the weir had 

been so damaged by a flood that a certain amount of leakage developed 

in the abutments. This damage, however, was shortly repaired, but 

no estimates are possible with the data collected.

At the gaging station there is a small channel to the right which 

carries water at high stages. Both banks are wooded and overflow 

at flood times.

The results obtained at this station will be valuable in connection 

with the proposed irrigation of lands in Goose Lake valley. A dam 

at the proposed site will develop about 30,000 acre-feet storage. 

These waters used in connection with those of Drews Creek will be 

sufficient to irrigate 60,000 acres of land.

The station is maintained in cooperation with the Oregon Valley 

Land Company, which has furnished the weir data and gage heights.

The following discharge measurement was made by R. B. Post:

' May 7,1909: Width, 26 feet; area, 41 square feet; gage height, 1.88 feet; discharge, 

118 second-feet.
