INTRODUCTION.

AUTHORITY FOR INVESTIGATIONS.

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

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

either independently or in cooperation with organizations mentioned 

herein. These investigations are authorized by the organic law of 

the Geological Survey (Stat. L., vol. 20, p. 39'4), which provides, 

among other things, as follows:

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

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

Inasmuch as water is the most abundant and most valuable 

mineral in nature, the investigation of water resources is included 

under the above provision for investigating mineral resources. The 

work has been supported since the fiscal year ending June 30, 1895, 

by appropriations in successive sundry civil bills passed by Congress 

under the following item:

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

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

The various appropriations that have been made for this purpose 

are as follows:

Annual appropriations for the fiscal year ending June 30 

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

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

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

1901 to 1902, inclusive............................................... 100, 000

1903 to 1906, inclusive............................................... 200, 000

1907................................................................. 150, 000

1908 to 1910, inclusive............................................... 100,000

SCOPE OF INVESTIGATIONS.

These investigations are not complete nor do they include all the 

river systems or parts thereof that might purposefully be studied. 

The scope of the work is limited to that which can be provided with 

the appropriations available. The field covered and the character 

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

under the controlling conditions. It would undoubtedly be of more 

scientific importance and ultimately of more practical value if the 

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

basins. Such a course is impossible because general appropriations 

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

part demands its proportionate share of the benefits.

It is essential that records of stream flow shall be maintained during a period of years sufficient to cover all stages, in order that within 

reasonable limits the entire range of flow from the absolute maximum 

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

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

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

more, the limit being determined by the relative importance of the 

stream and the interdependence of the results and other long-time 

records on adjacent streams.

In the performance of this work the Geological Survey endeavors 

to approach as nearly as possible the highest degree of precision 

which a rational expenditure of time and a judicious expenditure of 

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

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

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

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

the Survey are sufficiently accurate for all practical purposes. Many 

of the records are, however, of insufficient length, owing to the unforeseen reduction of appropriations and consequent abandonment of 

many stations. All persons are cautioned to exercise the greatest 

care in the utilization of such incomplete records.

Records of varying lengths have been obtained at about 1,400 different points in the United States, and in addition the surface water 

supply of small areas in Seward Peninsula and the Yukon-Tanana 

region, Alaska, has been investigated. During 1907 and 1908 regular 

gaging stations were maintained by the Survey and cooperating 

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

also obtained in regard to precipitation, evaporation, storage reser-

voirs, river profiles, and water power in many sections of the country. 

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

papers and in special papers from time to time.

PURPOSES OF THE WORK.

Among the purposes for which the results contained in this volume 

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

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

The demands of all these interests are immediate.

Navigation. -The Federal Government has expended more than 

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

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

the intelligent solution of the many problems involved.

Irrigation. The United States is now expending $42,000,000 on 

federal irrigation systems, and this amount is far exceeded by the private expenditures of this nature in the arid West. The integrity of 

any irrigation system is based absolutely on the amount of water 

available. Therefore investigations of stream flow in that portion 

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

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

Domestic water supply. The highest use of water is that of domestic supply, and while the federal interest in this aspect of the 

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

water nevertheless has so broad a significance with respect to the 

general welfare that the Federal Government is ultimately and intimately concerned.

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

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

power is increasing accordingly. Industry will cease its growth if 

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

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

open. When the electric transmission of power was accomplished, 

the relation of our water powers to national economy changed entirely. Previous to the day of electric transmission the importance 

of a water power was largely confined to the locality at which it was 

generated, but it has now become a public utility in which the individual citizen is vitally interested. Inasmuch as the amount of 

water power that may be made available is dependent on the flow 

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

judicious management of this source of energy.

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

acres of the richest land in this country are now practically worth-
8 SURFACE WATER SUPPLY, 1907-8.

less, 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 runoff is the first consideration in connection with drainage projects. 

If by the drainage of a large area into any particular channel that 

channel becomes so gorged with water that overflow conditions are 

created in places not previously subject to inundation, then drainage results merely in an exchange of land values. This is not the 

purpose of drainage improvement.

Flood prevention. The damage from floods in the United States 

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

damage, based on reliable data, approximated $250,000,000. Such 

an annual tax on the property of great regions should be reduced in 

the orderly progress of government. It goes without saying that any 

consideration of flood prevention must be based on a thorough 

knowledge of stream flow, both in the contributing areas which furnish the water and along the great lowland rivers.

PUBLICATIONS.

The data on stream flow collected by the United States Geological 

Survey since its inception have appeared in the annual reports, 

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

evolution and to changes in governmental requirements, the character 

of the work and the territory covered by these different publications 

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

States Reclamation Service, the United States Forest Service, the 

United States Weather Bureau, and the United States Geological 

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

divided into twelve parts, whose boundaries coincide with certain 

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

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

The dividing line between the North Atlantic and South Atlantic 

drainage areas lies between York and James rivers.

NOTE. No data regarding stream flow are given in the 1 Jth and 17th annual reports.

The records at most of the stations discussed in these reports 

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

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

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

numbers of the papers on surface water supply published from 1899 

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

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

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

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

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

relating to Platte and Kansas rivers.

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

downstream. The main stem of any river is determined on the
INTRODUCTION. 11

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 wide, 1 foot 

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

given in the following table of equivalents.

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

and city water supply.

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

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

It is commonly used by miners and irrigators throughout the West 

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

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

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

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

regards time and area.

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

be covered if all the water flowing from it in a given period were 

conserved and uniformly distributed on the surface. It is used for 

comparing run-off with rainfall, which is usually expressed in depth 

in inches.

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

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

used in connection with storage for irrigation work.
12 SURFACE WATER SUPPLY, 1907-8. 

CONVENIENT EQUIVALENTS.

The following is a list of convenient equivalents for use in hydraulic 

computations:

1 second-foot equals 40 California miner's inches (law of March 23, 1901). 

1 second-foot equals 38.4 Colorado miner's inches. 

1 second-foot equals 40 Arizona miner's inches.

1 second-foot equals 7.48 United States gallons per second; equals 448.8 gallons per 

minute; equals 646,272 gallons for one day. 

1 second-foot equals 6.23 British imperial gallons per second. 

1 second-foot for one year covers 1 square mile 1.131 feet or 13.572 inches deep. 

1 second-foot for one year equals 31,536,000 cubic feet. 

1 second-foot equals about 1 acre-inch per hour. 

1 second-foot for one day covers 1 square mile 0.03719 inch deep. 

1 second-foot for one 28-day month covers 1 square mile 1.041 inches deep. 

1 second-foot for one 29-day month covers 1 square mile 1.079 inches deep.

EXPLANATION OF TABLES.

For each drainage basin there is given a brief description of 

general conditions covering such features as area, source, tributaries, topography, geolog}T , conditions of forestation, rainfall, ice 

conditions, irrigation, storage, power possibilities, and other special 

features of importance or interest.

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

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

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

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

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

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

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

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

not used in these methods of computation.

In addition to statements regarding the location and installation 

of current-meter stations the descriptions give information in regard 

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

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

conditions of flow, and backwater; also full information regarding 

diversions which decrease the total flow at the measuring section. 

Statements are also made regarding the accuracy and reliability of 

the data.

The discharge-measurement table gives the results of the discharge 

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

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

discharge in second-feet.

The table of daily gage heights gives the daily fluctuations of 

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

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

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

the elevation of the surface of the wrater 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,
14 STJEFACE WATEE SUPPLY, 190*7-8.

The discharge measurements and gage heights are the base data 

from which the rating tables and monthly discharge tables are 

computed.

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

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

recorded during the period for which it is applicable. It is published 

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

of monthly discharge.

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

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

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

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

water surface was at crest height and the corresponding discharge 

consequently larger than given in this column. Likewise, in the 

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

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

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

month. On this the computations for the remaining columns, which 

are defined on page 11, are based.

FIELD METHODS OF MEASURING STREAM FLOW.

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

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

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

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

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

available, and the length of time that the record is to be continued.

Slope method. Much information has been collected relative to the 

coefficients to be used in the Chezy formula, V= c ^jRs. This has 

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

determining the values of the coefficient n which appears therein. 

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

approximate, owing to the difficulty in obtaining accurate data and 

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

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

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

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

reader is referred to the various text-books on hydraulics.

Weir method. Relatively few stations are maintained at weirs or 

dams by the United States Geological Survey. Standard types of 

sharp-crested and broad-crested weirs within the limits for which
IFTEODUCTION. 15

accurate coefficients have been experimentally obtained give very 

accurate records of discharge if properly maintained. At practically 

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

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

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

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

backwater at high stages, uncertainty regarding coefficient, crest 

which is not level, obstructions from logs or ice, use of flashboards, 

old turbines with imperfect ratings, and many others depending on 

the type of development and the uses of the diverted water.

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

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

experience of the United States Geological Survey, however, that 

records at current-meter gaging stations under unobstructed channel 

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

the conditions are reasonably favorable are practically as good as 

those obtained at sharp-crested weirs.

The determination of discharge over the different types of weirs 

and dams is treated fully in "Weir experiments, coefficients, and 

formulas" (Water-Supply Paper 200) a and in the various textbooks on hydraulics. "Turbine water-wheel tests and power tables" 

(Water-Supply Paper 180) treats of the discharge through turbines 

when used as meters. The edition of this water-supply paper is 

exhausted. It can, however, be consulted at most of the larger 

libraries of the country or can be obtained from the Superintendent 

of Documents, Washington, D. C., at a cost of 20 cents. Remittances 

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

Velocity method. Streams in general present throughout their 

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

location of the measuring section with respect to these physical 

conditions, current-meter gaging stations may in general be divided 

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

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

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

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

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

In determining the daily flow different office methods are necessary 

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

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

the same.

Great care is taken in the selection and equipment of gaging 

stations for determining discharge by velocity measurements, in 

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

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

between gage height and discharge will always remain constant 

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

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

requisite of any current-meter gaging station when maintained for 

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

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

streams is not attainable except at the cost of a cable equipment. Rough, permanent sections, if measurements are properly made by experienced engineers, taking measuring points at 

a distance apart of 2 to 5 per cent or less of the total width 

will within reasonable limits yield better results for a given outlay 

of money than semipermanent or shifting sections with smooth, 

uniform current. So far as possible, stations are located where the 

banks are high and not subject to overflow at high stages and out 

of the influence of tributary streams, dams, or other artificial obstructions which might affect the relation between gage height and 

discharge.

A gaging station consists essentially of a gage for determining 

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

apparatus from which discharge measurements are made, usually 

a bridge or cable.

The two factors required to determine the discharge of a stream 

past a section perpendicular to the mean direction of the current 

ar,e the area of the cross section and the mean velocity of flow normal 

to that section.

In making a measurement with a current meter a number of 

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

plane of the measuring section at which observations of depth and 

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

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

and are spaced unequally for other parts according to the discretion 

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

be spaced farther apart than 5 per cent of the distance between 

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

time of measurement.

The measuring points divide the total cross section into elementary 

strips at each end of which observations of depth and velocity 

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

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

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

strip. The sum of the discharges of the elementary strips is the total 

discharge of the stream. (For a discussion of methods of computing the discharge of a stream see Engineering News; June 25, 

1908.)

Depths for the determination of the area are usually obtained 

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

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

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

cross section.

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

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

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

of this method is limited to special conditions where it is impracticable 

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

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

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

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

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

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

used is the mean value obtained from several cross sections measured 

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

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

course used and uncertainty regarding the proper coefficient to 

apply to the observed velocity. For further information regarding 

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

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

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

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

determination of the velocity of flow of wT ater in open channels, a 

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

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

equipped for measurements at bridge and cable stations. On the 

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

method on the right. Briefly, the meter consists of six cups attached 

to a vertical shaft which revolves on a conical hardened steel point 

when immersed in moving wT ater. The number of revolutions is 

indicated electrically. The rating, or relation between the velocity 

of the moving water and the revolutions of the wheel, is determined 

for each meter by drawing it through still water for a given distance 

at different speeds and noting the number of revolutions for each 

run. (See PL I, A.} From these data a rating table is prepared 

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

of revolutions in a given time interval. The ratio of revolutions per

18 SURFACE WATER SUPPLY, 1907-8.

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 platting these velocities as 

abscissas and their depths as ordinates and drawing a smooth curve 

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

This curve shows graphically the magnitude and changes in velocity 

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

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

velocity curve and its axis by the depth. This method of obtaining 

the mean velocity in the vertical is probably the best known, but 

on account of the length of time required to make a complete measurement its use is largely limited to the determination of coefficients 

for purposes of comparison and to measurements under ice.

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

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

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

assumption that the vertical velocity curve is a common parabola 

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

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

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

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

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

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

practice of the United States Geological Survey.

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

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

which the coefficient for reducing to mean velocity has been determined or must be assumed.

Extensive experiments by means of vertical velocity curves show 

that the thread of mean velocity generally occurs between 0.5 and 

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

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

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

large number of vertical velocity curve measurements, taken on 

many streams and under varying conditions, show that the average 

coefficient for reducing the velocity obtained at 0.6 depth to mean 

velocity is practically unity. The variation of the coefficient from

PRICE PENTA-RECORDING CURRENT METERS.
INTRODUCTION. 19

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

0.8 methods and the general results are not as satisfactory.

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

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

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

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

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

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

method is especially adapted for flood measurements, or when the 

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

position for the other methods.

The vertical-integration method consists in moving the meter at a 

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

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

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

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

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

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

rapid enough to vitiate the accuracy of the resulting velocity.

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

owing to diversity and instability of conditions during the winter 

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

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

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

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

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

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

a series of curves) similar to that used for open channels, but considering, in addition to gage heights and discharge, the varying thickness of ice. For information in regard to flow under ice cover, see 

Water-Supply Paper 187.

OFFICE METHODS OF COMPUTING AND STUDYING DISCHARGE AND

EUN-OFF.

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

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

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

The rating tables prepared from these curves are then applied to 

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

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

are computed.
20 SURFACE WATER SUPPLY, 1907-8.

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 published rating table the following assumptions are 

made for the period of application of the table: (a) That the discharge is a function of and increases gradually with the stage; (6) 

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

stage, and hence such changes in conditions of flow as may have occurred during the period of application are either compensating or 

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

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

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

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

or compensating.

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

classes, as indicated in the following paragraphs:

The stations of class 1 represent the most favorable conditions for 

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

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

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

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

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

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

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

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

discharge. Discharge measurements made at such stations usually 

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

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

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

Paper 241.

Class 2 is confined mainly to stations on rough mountainous streams 

with steep slopes. (See fig. 1.) The beds of such streams are as a 

rule comparatively permanent during low and medium stages and when 

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

measurements before and after each flood the stations of this class 

give nearly as good results as those of class 1. As it is seldom pos-

sible 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.

Class 3 includes most of the current-meter gaging stations maintained by the United States Geological Survey. If sufficient 

measurements could be made at stations of this class results would 

be obtained nearly equaling those of class 1, but owing to the limited funds at the disposal of the Survey this is manifestly impossible, nor is it necessary for the uses to which discharge data are 

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

stages. The percentage error, however, is greater at low stages. No 

absolute rule can be laid down for stations of this class. Each rating 

curve must be constructed mainly on the basis of the measurements 

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

history of the station and the following general law: If all measurements ever made at a station of this class are plotted on cross-section 

paper, they will define a mean curve which may be called a standard 

curve. It has been found in practice that if, after a change caused by 

high stage, a relatively constant condition of flow occurs at medium 

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

smooth curve which is practically parallel to the standard curve with 

respect to their ordinates, or gage heights. This law of the parallelism of ratings is the fundamental basis of all ratings and estimates 

at stations with semipermanent and shifting channels. It is not 

absolutely correct, but with few exceptions answers all the practical 

requirements of estimates made at low and medium stages after a 

change at a high stage. This law appears to hold equally true 

whether the change occurs at the measuring section or at some controlling point below. The change is of course fundamentally due to 

change in the channel caused by cut, or fill, or both, at and near the 

measuring section. For all except small streams the changes in section usually occur at the bottom. The following simple but typical 

examples illustrate this law:

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

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

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

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

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

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

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

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

rarely exist.
INTRODUCTION. 23

(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 description of a station of this class see Water-Supply Paper 242.

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

Good results can be obtained from such sections only by frequent 

discharge measurements, the frequency varying from, a measurement every two or three weeks to a measurement every day, according to the rate of diurnal change in conditions of flow. These 

measurements are plotted and a mean or standard curve drawn 

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

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

standard curve with respect to their ordinates. On the day of a 

measurement the rating curve for that day passes through that 

measurement. For days between successive measurements it is 

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

for the intervening days are equally spaced between the ratings 

passing through the two measurements. This method must be

modified or abandoned altogether under special conditions. Personal judgment and a knowledge of the conditions involved can 

alone dictate the course to pursue in such cases. For illustrative 

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

determining the daily discharge graphically, see Water-Supply 

Papers 247 and 249.

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

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

rule have been generally used. All computations are carefully 

checked.

After the computations have been completed they are entered in 

tables and carefully studied and intercompared to eliminate or 

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

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

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

notes accompanying such estimates follow the monthly discharge 

tables.

For most of the northern stations estimates have been made of 

the monthly discharge during frozen periods. These are based on 

measurements under ice conditions wherever available, daily records 

of temperature and precipitation obtained from the United States 

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

adjacent streams. Although every care possible is used in making 

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

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

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

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

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

annual discharge. The large error of the individual months has a 

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

some error is involved in doing so.

ACCURACY AND RELIABILITY OF FIELD DATA AND COMPARATIVE

RESULTS.

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

observation. Inasmuch as the errors of meter measurements are 

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

much more accurate than the individual measurements. Numerous 

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

results from standard weirs, and, owing to simplicity of methods,
INTRODUCTION. 25

usually gives results that are much more reliable than those from 

stations at dams, where uncertainty regarding the coefficient and 

complicated conditions of flow prevail.

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

With relatively few exceptions, the observers perform their work 

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

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

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

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

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

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

In order to give engineers and others information regarding the 

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

rating tables and an accuracy column is inserted in the monthly discharge table. In the rating tables "well defined " indicates in general 

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

defined," within 10 per cent: "poorly defined" or " approximate," 

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

on the plotting of the individual measurements with reference to the 

mean rating curve.

The accuracy column in the monthly discharge table does not apply 

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

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

this column, A indicates that the mean monthly flow is probably 

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

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

USE OF THE DATA.

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

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

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

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

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

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

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

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

year nearly always throw new light on data already collected and 

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
26 SURFACE WATER SUPPLY, 1907-8.

more is carried on by the United States Geological Survey so far as 

the funds for such work are available.

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

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

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

estimates. This is particularly true of the maximum and minimum 

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

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

t increased considerably for many stations in considering designs for 

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

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

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

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

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

other method.

GENERAL DESCRIPTION OF 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 pla-

teaus,, 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; 

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, YVinnemucca, Honey, TYalker, 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 play as.

Geological!}' 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
28 SURFACE WATER SUPPLY, 1907-8.

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.

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 

frcm 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 1907 and 1908 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, 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 exten-

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

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 L^tah 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 Collinston the Bear flows sluggishly along the 

west side of Cache Valley in a well-defined channel, and during
30 SUKFACE WATER SUPPLY, 1907-8.

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 

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 Collmston in the year being 2,680,000 acrefeet; in 1890, 1894, 1897, 1899, and 1907 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, 1903-1908.

Bear River near Preston, Idaho, 1889-1908.

Bear River near Collinston, Utah, 1889-1908.

Bear Lake at Fishhaven, Idaho, 1904-1906.

Cub Creek near Franklin, Idaho, 1900-1901.

Logan River near Logan, Utah, 1896-1908.

BEAR RIVER AT DINGLE, IDAHO.

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

discharge available for storage in Bear Lake, is located about 10 

miles above the outlet of Bear Lake, below the proposed intake of the 

diversion canal to the lake (see PI. Ill, A], and above all important 

diversions.

The station is situated in a cut-off built by the Oregon Short Line 

Railroad Company. Measuring conditions are excellent, the channel 

is fairly permanent, and records for the open-water season are very 

reliable. The river is frozen over from about December 1 until the 

middle or last of March, the ice gradually increasing to a thickness of 

about 1.2 feet. No anchor or needle ice forms and fairly accurate 

estimates of discharge during the frozen period can be made. These 

estimates are specially important, as in the winter season all the 

water is available for diversion into Bear Lake.

a River probably blocked with ice above gaging station, thus shutting off the water and releasing it in 

the two or three days following.

NOTE. The river was frozen over January 1 to March 9, 1907; the ice increased in thickness from 0.6 

foot, January 6, to 1.2 February 7 to 22; decreased to 0.6 foot March 7, and was gone March 18. Ice conditions November 25 to 28, 1907, and from about December 18, 1907, to March 17. 1908; the ice reached, 

a maximum thickness of 1.2 feet February 1 to 15, 1908. River began to freeze November 14, 1908, but 

probably was not frozen over until about December 20.

NOTE. The discharges for ice periods were determined as follows: For February, 1907, an ice rating 

table was used, based on measurements in 1904 to 1906 under ice conditions similar to those existing in 

February, through ice 1 to 1.2 feet thick. For January and March 1 to 9, discharges were estimated by a 

transition between this table and that for the open channel periods before and after, taking into account 

the thickness of ice. November 25 to 28 were interpolated on account of slush ice. For January 19 to 

March 14, 1908, an ice table was used, parallel with respect to gage height to that used in February, 1907, 

and 0.35 foot higher, this being the amount that the 1908 open water rating plots above that for the period 

before the high water of 1907. December 18, 1907, to January 18, 1908, estimated by transition between 

open water and ice tables; March 15 to 17 interpolated. For December 21 to 31, ice has been assumed to 

be 0.5 foot thick.

BEAR RIVER NEAR PRESTON, IDAHO.

This station, which is situated at the upper end of Cache Valley, 

about 6 miles from Preston, Idaho, and 10 miles north of the IdahoUtah state line, has been maintained continuously since October 11, 

32606 IRR 250 10 3
34 SUEFACE WATER SUPPLY, 1907-8.

1889. The records are necessary to determine the amount of water 

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

Cub Creek and Logan River enter the Bear in the valley below 

the station. Few diversions are made above, but large areas of 

irrigable land are available. It is possible to divert the river from a 

point near Soda Springs, at the north end of the Bear River Range, 

over the divide to lands adjacent to Portneuf River, a tributary of 

the Snake.

More or less ice forms at this station for two or three months 

during the winter. The river seldom freezes over, but when the 

morning gage readings show the effect of anchor and slush ice the 

afternoon readings have been used. The channel shifts slightly 

during floods but measuring conditions are good.

NOTE. The river is known to have been frozen or the gage heights to have been affected by slush or 

anchor ice during the following periods: January 1 to 26, February 7 to 9, and November 18 to 27, 1906; 

December 17 to 24,1907; February 4 to 9, November 29 to December 3, and December 17 to 27,1908. There 

was slush ice in the morning at other times during December to March, but the afternoon readings were 

unaffected and have been used. There was some obstruction from ice from about January 1 to February 

10, 1907, which probably did not materially affect the gage readings.

OTE. In computing the above discharges the following corrections and estimates have been made: 

, January 1 to 18, interpolated; February 10 to 20, interpolated with measurement of February 17;

September 24 to October 15, 1908, and December 22 to 28, 1908, interpolated.

BEAR RIVER NEAR COLLINSTON, UTAH.

This station, which is located 6 miles north of Collinston station, 

on the Oregon Short Line Railroad, about one-fourth mile below 

the electric-power plant in Bear River canyon, was established 

July 1, 1889, and has been kept continuously since that date. From 

July 6, 1906, to August, 1907, however, only weekly gage readings 

were obtained.

The station is at the lower end of the canyon separating Cache 

and Great Salt Lake valleys and is below all diversions from the 

stream. The records show the amount of unappropriated water discharged into Great Salt Lake. Malade River is the only tributary 

below this point.

Almost the entire summer flow of the stream in years of low water 

is diverted by the Bear River Canal Company at a point above the 

station to agricultural lands on both sides of the river below the 

canyon. The system has a capacity of about 1,000 second-feet, 

and during the winter and flood seasons a part of the water is used
38 SUEFACE WATER SUPPLY, 1907-8.

to develop electric power above the gaging station and is returned 

to the river.

Bear River seldom freezes over at this station. During December 

and January ice forms in a narrow strip along each bank, but does 

not appreciably affect the determination of discharge.

The stream bed at the section has not changed in several years 

and records are very reliable. Changes of load at the power plant 

above and changes in the amount of diversion in canals may, however, cause sudden fluctuations in gage heights.

NOTE. Daily discharges for January 1 to August 15, 1907, were obtained from weekly gage readings by 

the aid of a hydrograph, following the rate of rise and fall of the river at the Preston station.

LOGAN RIVER NEAR LOGAN, UTAH.

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 numerous short and swift 

tributaries. Temple Fork and South Fork, which enter, respectively,
BEAK RIVER BASIN. 41

about 10 and 15 miles above the Logan, are perennial streams and 

furnish one-third to one-fourth of the total flow. Blacksmith Fork 

comes in below the 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.

A gaging station was established June 1, 1896, about 2 miles east 

of the city of Logan, near the mouth of the canyon. It was discontinued July 18, 1903, and reestablished April 13, 1904, at a point 

along the canyon road about 50 feet below the highway bridge, at 

the mouth of the canyon, 800 feet below the Hercules power house 

and about 1,000 feet above the old gaging station.

This point is above Blacksmith Fork and Cache River and is below 

all other tributaries. It is above all diversions except the Logan, 

Hyde Park, and Smithfield canal. Records have been kept on this 

canal at various times in order to determine the total flow of the river. 

(See p. 45.) The drainage area is 218 square miles.

The gage was moved downstream about 400 feet January 1, 1906. 

The datum has not been changed since that date.

Practically no ice forms at this station and measuring conditions 

are fairly good, but the channel shifts considerably. Velocities are 

so high that bowlders and gravel are moved along the river bed 

during floods. The results are therefore liable to some error.

NOTE. These discharges supersede those published in Water-Supply Paper 212, p. 27. Five secondfeet have been deducted from the discharge of the canal, November 14 to 20, and 27 to December 31, this 

amount having been spilled into the river below the station on the canal and above the station on the river. 

Discharge measurements and gage heights for 1906 are given in Water-Supply Paper 212, pp. 26-27.

NOTE. These discharges do not include the flow of the Logan, Hyde Park, and Smithfleld canal, which 

diverts water past the station. The records on the canal for 1904 to 1907 give an approximate Idea of the 

amount of diversion for other years. (See p. 45.)
BEAE KIVER BASIN. 45

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

This canal diverts water for irrigation and domestic use in the 

three towns. Records are fragmentary. Gage heights are available 

for parts of 1904 and 1905, for the entire year 1906, and for part of 

1907.

The channel is permanent, however, 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 gage in the canal is above a spillway which discharges into the 

river above the station. The amount spilled has usually been estimated by the observer and has been deducted from the total discharge 

obtained as indicated above.

a Gage heights for 1904 are given in Water-Supply Paper 133, p. 248, for September 17 to 23, 1905; they 

ranged from 4.45 to 4.47. This is the only portion of 1905 for which records are available.

NOTE. Water was spilled from the canal below the gage into the river above the station on the latter, as 

follows: November 14 to 20, and November 27 to December 31, 1906, 5 second-feet; January 1 to May 31, 

1907, 2 to 7.5 second-feet; August 26 to December 31,1907, 1 to 10 second-feet. These figures are very uncertain, as they were only estimated by the observer.

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 on Blacksmith Fork was established July 19, 1900, near 

the tollgate in the mouth of the canyon near Hyrum, Utah, and was 

discontinued December 31, 1902. It was reestablished May 16, 1904, 

about 1,000 feet farther downstream, 800 feet above the Hyrum city 

power plant and 500 feet below the intake of the power canal or race.

A station was established on the power-plant race on the same date, 

to determine the amount diverted past the station on the river. The 

combined records show the total supply in Blacksmith Fork above 

diversions for irrigation.
48 SURFACE WATER SUPPLY, 1907-8.

Ice does not form at either gage, and conditions at both stations 

are good, although the channel of the river shifts slightly at high 

stages, owing to the very swift current.

52 SURFACE WATER SUPPLY, 1907-8. 

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. Numerous 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 conies 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 ex-
WEBER RIVER BASIN. 53

tent, 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 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.

At 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 1907, when 

1,270,000 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 Great Salt Lake.

The gaging stations maintained in this basin are as follows:

Weber River near Oakley, Utah, 1904-1908. 

Weber River near Croyden, Utah, 1905-1908. 

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

Weber River near Plain City, Utah, 1903-1908. 

Lost Creek near Croyden, Utah, 1905. 

Chalk Creek at Coalville, Utah, 190-1-5. 

Ogden River at Ogden, Utah, 1895-1901.

WEBER RIVER NEAR OAKLEY, UTAH.

This station, which is located about 3 miles above Oakley, Utah, 

200 feet south of the main canyon road, was established October 

22, 1904, to determine the amount of water available for diversion 

through the low Kamas Pass into Provo River in connection with 

the Weber River project.

The station, which is about 6,600 feet above sea level, is below 

South Fork, above Beaver or Kamas Creek, and above all diversions 

to the Kamas prairie region.

The river is frozen two or three months during the winter, sometimes to a depth of nearly a foot, and occasionally forms jams when 

it goes out. Gage heights are also affected by slush and anchor 

ice. Fairly reliable estimates of discharge for the winter period 

can, however, be made by interpolating between days when open 

water is known to have existed, as the winter discharge varies little. 

The channel is permanent and records for the open-water periods 

are good.

WEBER RIVER NEAR CROYDON, UTAH.

This station, which is located at Devils Slide, about 1^ miles west 

of the town of Croydon and 10 miles below the town of Echo, just 

below the canyon at the lower end of Henefer Valley, 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 Weber River project.

Lost Creek enters one-fourth mile above the station and Chalk 

Creek about 15 miles above. The only diversions above the station 

are those in the Kamas prairie region and for the narrow valley 

below.

The flow is apparently little affected by ice. The occurrence of 

slush ice is noted, but no allowance is made for this. Otherwise the 

records are good, although the channel shifts slightly at high water. 

(See fig. 1, p. 21.)

WEBER RIVER BASIN. 59

WEBER RIVER NEAR PLAIN CITY, UTAH.

This station was established in 1903 under the direction of the 

state engineer of Utah, and was maintained by the State until 

May 14, 1905, when it was taken up by the United States Geological 

Survey in cooperation with the State. It is located at the highway 

bridge on the main road to Plain City and West Weber, 10 miles 

east of Ogden, and below all diversions and tributaries.

The records show the amount of water discharged into Great 

Salt Lake, information necessary for the adjudication of water rights 

on Ogden and Weber rivers.

Ice seldom affects the gage readings, although the river freezes 

occasionally during extremely cold weather. The current is very 

sluggish at low wrater, but at high stages the velocity reaches 3 

feet per second and the bed, being composed of clay, sand, and 

gravel, shifts slightly. A good rating curve has usually been developed for the period between floods.

Discharge measurements of Weber River near Plain City, Utah, in 1907 and 1908.

PROVO RIVER BASIN.

DESCRIPTION.

Provo River rises in the Uirita 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.

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
PROVO RIVER BASIN. 63

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-

1908.

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 total flow of the river into this valley, takes the place of the 

station at the mouth of the canyon, which has been maintained since 

1889. It is located about one-half mile below Forks station, on the 

Provo Canyon branch of the Denver and Rio Grande Railroad, about 

4 miles above the mouth of the canyon.

The station is below South Fork and all other tributaries and above 

all diversions into Utah Lake Valley. Some water is diverted for 

irrigation in Heber Valley above the station.

Little ice forms at this station. The gage heights have been somewhat affected by backwater from the diversion down below. This 

dam was raised about July 12, 1908, and the station had to be moved 

upstream a quarter of a mile, as near the forks as possible, but it is 

still too near the dam and results since that time have not been 

satisfactory.

Proro, Utah, in 1906-1908.

NOTE. There was little or no ice during 1907 or 1908. Gage heights July 12 to 24, 1908, were affected by 

backwater from the diversion dam and have been omitted. Gage heights for the two months previous 

are liable to be somewhat in error on this account. Gage heights beginning July 25 are for the new station

NOTE. This table is not applicable for ice or obstructed-channel conditions below gage height 5.5 feet. 

It is based on 14 discharge measurements made during 1905-1907, and is fairly well denned between gage 

heights 3.7 feet and 5.5 feet. Above gage height 5.5 feet the rating curve is drawn to average the three 

measurements, two of whichwereprobably made when the gage was affected by backwater from the diversion dam of the power flume. It is not the normal curve but probably gives the best average results.

PROVO RIVER AT MOUTH OF CANYON NEAR PROVO, UTAH.

This station, which was located about 6 miles above Provo and 

1,200 feet above the power house of the Telluride Power Company, 

was established July 27, 1889, to determine the amount of water 

available at the mouth of the canyon for irrigating lands near Utah 

Lake, and was discontinued June 30, 1906. The station established 

February, 1905, 4 miles above the mouth of the canyon and above 

the dam of the Telluride Power Company, now furnishes the necessary data, the discharge being practically the same at the two points.

The discharge of the Telluride Power Company's flume has been 

added to that at the station to give the total of the river. Discharges 

were omitted from the 1906 report but are included here for comparative purposes. No discharge measurements were made in 1906.

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.
68 SURFACE WATER SUPPLY, 1907-8.

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

greatest run-off was probably 1907, as on other streams in the vicinity, 

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, 1904-1908.

HOBBLE CREEK NEAR SPRINGVILLE, UTAH.

This station, which is located about 1 mile above the mouth of the 

canyon, 4 miles southeast of Springville electric-power plant, was 

established March 23, 1904, to determine the total discharge of the 

creek available for irrigation in connection with the Strawberry 

Valley project of the United States Reclamation Service. The 

station is above all diversions and below all tributaries.

Practically no ice forms at the station, as the normal winter flow 

comes largely from springs. The channel is composed of loose, fine 

gravel and shifts almost constantly. As sufficient measurements 

can not as a rule be made to determine the amount of change, the 

results obtained are liable to considerable error. Discharges for 

1906 and the early part of 1907 can not be computed because of 

insufficient data.

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 very little timber or brush. The stream is confined to 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,
SPANISH FOKK BASIN. 71

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. (See PI. Ill, B.)

During the period for which records are available the wettest }rear 

was 1907, when discharge at the station at the mouth of the canyon, 

near Spanish Fork, was 203,000 acre-feet, of which 98,500 acre-feet 

wasted into Utah Lake, according to the records at the Lake Shore 

station. The driest year according to the above records was 1905, 

when 65,810 acre-feet was 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:

SpanishFork at Thistle, Utah, 1908. 

Spanish Fork near Spanish Fork, Utah, 1900-1908. 

Spanish Fork near Mapleton, Utah, 1900-1901. 

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

Diamond Fork near Thistle, Utah, 1908.

SPANISH FORK AT THISTLE, UTAH.

This station, which was established December 3, 1907, is located 

one-half mile below Thistle station on the Denver and Rio Grande 

Railroad, just below the mouth of Thistle Creek and about 2 miles 

above the mouth of Diamond Fork. Gage height records began 

January 11, 1908.

The flow is uninfluenced by diversion or storage. The gage 

heights are often affected by ice during the winter. The section is 

permanent except during extreme floods and results for the openwater period are good.

SPANISH FORK NEAR SPANISH FORK, UTAH.

This station, which is located 600 feet above the dam of the East 

Bench Irrigation Company, 5 miles southeast of Spanish Fork, was 

established May 23, 1900, discontinued November 30, 1901, and 

reestablished March 26, 1903, to determine the total water supply 

from Spanish Fork available for irrigating lands near Utah Lake. 

The records are of special importance to the United States Reclamation Service in connection with Strawberry Valley storage reservoir 

project.

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

some water past the station during the last part of 1908.

Results at the station are little affected by ice, the river freezing 

only in exceptionally cold weather. The bed of the stream is composed of sand and gravel, and as the current is swift, especially at 

high water, the channel is somewhat shifting. Satisfactory results, 

however, have usually been obtained.

NOTE. Discharge estimated December 18 to 31, 1908.

SPANISH FORK NEAR LAKE SHORE, UTAH.

This station, which was located about 3 miles west of the town of 

Spanish Fork and about 3 miles from Utah Lake, was established 

December 10, 1903, to determine the amount of unappropriated 

run-off discharged into Utah Lake, and was discontinued July 10, 

1907. The entire normal summer now is diverted above the station, 

and the stream is dry from some time in June and July until about 

December 1.

The records have been little affected by ice. The bed is of a very 

shifting character and results have been rather unsatisfactory. 

Gage heights prior to May 26, 1904, were observed on a gage just 

below the bridge on the highway from Spanish Fork to Lake Shore. 

After that time they were read from a gage at the cable, 800 feet 

above the bridge. All gage heights for 1904 have been reduced to 

corresponding readings on the old gage.

78 SURFACE WATER SUPPLY, 1907-8.

DIAMOND FORK NEAR THISTLE, UTAH.

Diamond Fork (also known as North Fork) is tributary to Spanish 

Fork about 2 miles below the mouth of Thistle Creek. The gaging 

station, which was established December 2, 1907, is located about 

one-fourth mile above the mouth.

The Strawberry Valley tunnel will discharge into the headwaters 

at an elevation of nearly 7,500 feet. At present the run-off at the 

station is unaffected either by diversion or storage. Results are 

rendered somewhat inaccurate by shifting channel, and during the 

winter by ice.

SEVIEB RIVER BASIN. 

DESCRIPTION.

Sevier River 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
80 SUKFACE WATER SUPPLY, 1907-8.

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 River 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 manitained in this basin:

Sevier River near Marysvale, Utah, 1906-1908. 

Sevier River near Gunnison, Utah, 1900-1908. 

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 River, is located about 6 miles above Marysvale, 

the nearest railroad station, and about 10 miles below the junction of 

South and East forks.

A gage for high-water records was established May 23, 1906, at a 

different datum from that of the regular gage and was read until 

June 9, and for a few days thereafter. All gage heights have been 

reduced to the datum of the regular gage.

The results are somewhat affected by ice during severe weather, 

but are otherwise fairly reliable. The stream bed is of clay and will 

shift occasionally at high water. Gage-height records have not been 

obtained continuously.

SEVIER RIVER NEAR GUNNISON, UTAH.

This station, which was established June 29, 1900, to obtain data 

for use in connection with irrigation in the Sevier Valley, is located 

about 4 miles west of Gunnison, Utah, on the road to Westview precinct. It is about three-fourths of a mile above the mouth of San 

Pitch Kiver and below all other tributaries of importance.

The river freezes occasionally during the winter and the channel is 

liable to shift slightly during floods, but on the whole the records 

obtained are good.

a Gage heights for 1906 are given in Water-Supply Paper 212, p. 46. Those for July 1 to 11 are 1.4 too high.

NOTE. Discharges estimated on account of ice conditions, January 1 to 19, 1906, and December 19 to 

31,1908; the open-channel rating was applied the rest of the three years, though there may have been some 

ice. Discharges interpolated on days when gage was not read.

HTJMBOLDT SINK DRAINAGE BASIN.

HUMBOLDT RIVER. 

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 is in general through a barren region destitute of large 

trees and supporting few shrubs except scattered clusters of willows. 

Affording the only east and west pass through the mountains of 

Nevada, the valley of the main stream 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 the 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.

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 Golconda, Nev., 1894-1908.
HUMBOLDT SINK DRAINAGE BASIN. 87

Humboldt River near Oreana, Nev., 1896-1908.

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., 1902-1908.

South Fork of Humboldt River near Elko, Nev., 1896-1908.

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 1| miles north of the town of 

Golconda.

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 lowwater flow being used for irrigation.

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

information as to winter conditions is meager.

Two gages have been used at this station, the difference in datum 

being 0.1 foot, and the observers' records do not always specify 

which gage was used. 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.

NOTE. Gage heights for 1907 were read from the gage at the wagon bridge. This gage was washed away 

in December. The gage used in 1908 was the old gage on the left bank, which read 0.1 foot higher than 

the gage at the bridge.

NOTE. The river was frozen December 16 to 31,1908; there was a little ice in the first half of the month; 

the effect on the discharge was urobably very slight. The 1908 gage heights refer to a datum 0.1 foot lower 

than those of 1907.

fairly well defined. The change in conditions between the last measurement of 1907 and the first of 1908 

may have taken place gradually, but in the absence of definite information it has been assumed to occur 

on January 1, which was the highest water of the period.

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 channel is very unstable and sufficient measurements have not 

been made to give results that are entirely satisfactory or reliable.

NOTE. Discharges estimated January 29 to February 7, and December, 1908.

NORTH FORK OF HUMBOLDT RIVER NEAR 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. Records at this point show 

the total flow of the river.

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.

and 1908.

SOUTH FORK OF HUMBOLUT 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. 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.

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 1908 the gage heights were affected by the raising of 

a diversion dam below. As sufficient measurements have not yet 

been made to indicate the extent of these changes the published 

estimates of discharge are only approximate.

NOTE. This table is not applicable for ice or obslrucled-channel conditions. It is based on one discharge 

measurement made during 190S, and is well defined only for medium stages in midsummer. For low 

water it is only approximate. The last change in the diversion dam noted by the observer occurred on 

May 22, and raised the gage height 0.3 foot or about the same as the difference between this and the previous table. The dam has been assumed to remain constant until the end of the year.

100 SURFACE WATER SUPPLY, 1907-8.

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 ari 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 

Valley, the Reno or Truckee Valley, and the Wadsworth Valley. All 

three have a rich, productive soil. The total length of the Truckee is 

about 110 miles and its total 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.

TRUCKEE RIVER BASIN. 101

Three power plants have been installed on the Truckee: The 

Farad (Mystic), Fleish, and Washoo plants, with an emergency 

plant near Reno, Nev. (See PI. V, B.} 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, Eeno, Carson City, 

Yerington, Gardnerville, Sparks, and Virginia City, Nev. There 

are many falls on the headwaters of the small tributaries. (See PL 

V, A.)

Almost all of 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, 1900-1901, 1907-8.

Truckee River at Tahoe, Cal., 1895, 1900-1908.

Truckee River near Boca, CaL, 1890.

Truckee River at Nevada-California state line, 1899-1908.

Truckee River near Laughtons, Nev., 1890.

Truckee River at Reno, Nev., 1906-1908.

Truckee River near Essex, Nev., 1889.

Truckee River at Vista, Nev., 1890-91, 1899-1907.

Truckee River at Derby dam, Nev., 1907-8.

Truckee River near Wadsworth, Nev., 1902-1905.

Lake Winnemucca Inlet near Wadsworth, Nev., 1902-1905.

Donner Creek near Truckee, CaL, 1902-1908.

Prosser Creek near Hobart Mills, CaL, 1903-4, 1907-8.

Prosser Creek near Boca, CaL, 1889-90, 1902-3.

Independence Creek below Independence Lake, CaL, 1902-1906.

Little Truckee River at Pine Station and Starr, CaL, 1903-1908.

Little Truckee River near Boca CaL, 1890.

Steamboat Creek at Steamboat Springs, Nev., 1900-1901.

LAKE TAHOE AT TAHOE, CAL.

Lake Tahoe lies on the boundary between Nevada and California, 

at an elevation of 6,225 feet above sea level, and has an area of 

124,000 acres, or about 193 square miles. It is the largest body of 

water at so high an elevation in the United States. (See PI. IV.)

Records of the height of the lake have been kept to determine its 

fluctuation and the approximate amount of water drawn from 

storage.

TRUCKEE RIVER 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 15 or 20 second-feet, 

or the amount of leakage through the dam.

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.

TEUCKEE EIVEE AT NEVADA-CALIFOENIA 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.

The gage is located at Farad, 1\ miles above the measuring section. 

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.

Discharge measurements of Truckee River at Nevada-California state line, in 1907 and 1908.

TRUCKEE RIVER AT VISTA, NEV.

This station, which is located 7 miles east of Reno and one-fourth 

mile from Vista railroad station, was established August 18, 1899, to 

determine the amount of water available below the Truckee Valley 

for use of the main canal of the Truckee-Carson project, which takes 

water from the river about 16 miles below.

The gage has been washed out, replaced, and moved several times. 

The gage used April 16 to December 31, 1907, has no determined 

relation to previous gages, as it was in a different location. Measurements in 1907 were made at a cable below the railroad bridge where 

the gage was located, and were referred to a gage at the cable as well 

as to the regular gage.

NOTE. The gage was washed out March 19, 1907. On April 17 the observer recommenced readings by 

measuring from the top of the west abutment of the railroad bridge. The gage heights after that are referred 

to this point, assumed elevation 20.0 feet. Readings for August to December are somewhat uncertain, but 

comparisons with records at the Derby dam station tend to confirm them.

TRUCKEE RIVER AT DERBY DAM, NEV.

This station, which is located about 2 miles east of Clarks, Nev., 

three-fourths mile above the Reclamation Service diversion dam for 

the main canal of the Truckee-Carson project (see PL VI), 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. This station replaces the station at 

Vista, giving practically the same record. Results obtained at this 

station are good.

TRUCKEE EIVER BASIN. 113

DONNER CREEK NEAR TRUCKEE, CAL.

Donner Creek flows from the east end of Donner Lake eastward 

into Truckee River about 1J 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.

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.

PEOSSER CREEK NEAR HOBART MILLS, CAL.

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.
116 SURFACE WATER SUPPLY, 1901-8.

The section is permanent, but results are considerably affected by 

ice. No measurements have yet been obtained at extreme low stages.

LITTLE TRUCKEE RIVER AT *PINE STATION AND STARR, CAL.

Little Truckee River rises on the eastern slope of the Sierra Nevada, 

in northwestern Xevada 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. (See PI. 

V, A.) 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.

Results 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.

SUEFACE WATER SUPPLY, 1907-8. 121 

CARSON RIVER BASIN. 

DESCRIPTION.

The Carson River basin includes that area which lies 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. 

Carson River near Empire, Nev., 1900-1908. 

Carson River near Hazen, Nev., 1908. 

West Fork of Carson River at Woodfords, Cal., 1900-1908.

EAST PORK 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, 1908, 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
122 SURFACE WATER SUPPLY, 1907-8.

above all diversions. Measuring conditions are favorable, the section 

is permanent, and results are good.

CARSON RIVER AND BRUNSWICK MILL POWER CANAL NEAR EMPIRE,

NEV.

This station, which was established October 21, 1900, was originally 

located three-fourths mile east of Brunswick Mill and 2J miles 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, 1^ 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 

moved to the county bridge at Brunswick Mill, 500 feet below. All 

gage heights since that time refer to the same datum. 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 water is now used to pump water for irrigation, although formerly it was used to run a stamp mill.

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 an 

index of the discharge for only a part of the time. Discharges for the 

canal are therefore only approximate. Ice interferes with records 

at times during the winter.

backwater, and partly by interpolation between measurements, and are approximate. The discharge of 

the canal seems to remain fairly constant, and was probably about the same for 1907.

CARSON RIVER NEAR HAZEN, NEV.

This station, which is located about 16 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. Sufficient measurements have not yet been 

made to define a rating curve for this station.

NOTE. The river was dry or standing in pools July 30 to October 4; gage heights estimated October 5

part of the time.

WEST FORK OF CARSON RIVER NEAR WOODFORDS, CAL.

West Fork of Carson River rises 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.

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. Sufficient measurements have not 

yet been referred to the new gage to define a rating curve. The 

extent of ice conditions during the winter is not definitely known.

SURFACE WATER SUPPLY, 1907-8. 131 

WALKER RIVER BASIN. 

DESCRIPTION.

Walker River rises on the eastern slope of the Sierra Nevada in two 

main branches whose basins are separated by a group of mountains 

known as the Sweet water Range. The East Fork of Walker River 

recedes the drainage from the eastern slope of the Sweetwater Range 

and from the western slope of the Walker River Range; the West 

Fork flows at the base of the main range of the Sierra Nevada. From 

the union of the forks, near Yerington, the river flows sluggishly northward, passing through the fertile Yerington Valley (Mason Valley) to a 

point east of Wabuska, where it turns to the east and southeast, and 

60 miles beyond enters Walker Lake. The length of the river is 

about 120 miles, in which distance its fall is about 1,600 feet.

The basin contains but three important valleys Antelope Valley 

on the West Fork, Smith Valley, a fertile tableland presenting ample 

opportunity for reclamation, also under the West Fork, and Yerington 

Valley, which takes its water from the two forks. Only recently have 

the water rights in this last-named valley been adjusted. The minimum flow is not sufficient to supply the demand during the summer 

months, although excellent reservoir sites near the headwaters of the 

forks are available for storing the flood waters for use during the dry 

season. The snowfall in the winter months is very heavy, giving 

assurance of an ample supply for reservoirs.

No irrigation projects are at present being constructed, but surveys have been made b}r the Reclamation Service to show the feasibility of such projects. A line of levels run by the Reclamation 

Service from a point above Yerington to Carson River near Towle's 

ranch shows that water can be easily diverted by gravitation from 

Walker River to the Carson. The opportunities for power development afforded by both forks are as yet undeveloped by private 

companies because of the small demand for power near the rivers. 

Power development from the main stream is not feasible.

Only three gaging stations have been maintained for any great 

length of time in the Walker River drainage basin, and these were 

discontinued July 31, 1908, owing to lack of funds.

The stations are as follows:

East Fork of Walker River near Yerington, Nev., 1902-1908.

Walker River near Nordyke, Nev., 1895.

Walker River near Wabuska, Nev., 1902-1908.

West Fork of Walker River near Coleville, Cal., 1902-1908.

Very reliable estimates of flow of the river can be obtained by 

adding the run-off of the two forks.
132 SURFACE WATEK SUPPLY, 1907-8.

EAST FORK OF WALKER RIVER NEAR YERINGTON, NEV.

This station, which was established October 6, 1902, to determine 

the quantity of flow available for storage and irrigation, was located 

at Koss ranch, about 10 miles southeast of Yerington, Nev., near the 

junction with West Fork. The station was discontinued July 31,1908.

The stream bed is of shifting sand and clay, and satisfactory 

results could not be obtained with the small number of measurements that could be made. Information as to ice conditions is

WALKER RIVER NEAR WABUSKA, 1STEV.

This station, which was located about 300 feet above the Carson 

and Colorado Railroad bridge, near the section house at Clever 

station and about 2^ miles east of Wabuska, was established July 22, 

1902, to determine the amount of water flowing into Walker Lake 

and also the amount of water returned by seepage, as the locality 

is below all diversions for irrigation. The station was discontinued 

July 31, 1908. The gage datum has remained unchanged.

The records are unreliable because of the shifting river bed. For 

1908, gage heights only are available.

conditions and lack of measurements.

WEST FORK OF WALKER RIVER NEAR COLEVILLE, CAL.

This station, which was established October 5, 1902, to determine 

the total flow of the river above all diversions and to obtain for the
WALKER RIVER BASTTST. 137

Reclamation Service reliable data concerning storage and irrigation 

opportunities, was discontinued July 31, 1908. The data were also 

used by the Nevada state engineer in adjusting water rights in Smith 

and Antelope valleys.

The cable was located about 1 mile east of the point where the 

main road from Topaz to Bridgeport crosses Lost Canyon Creek and 

is 600 feet from the road. The gage was about one-half mile above 

the cable.

The gage datum remained unchanged during the continuance of the 

station. The channel is permanent, the flow is apparently unaffected 

by ice or artificial control, and the record is good.

GREAT BASIN" DRAINAGE AREA IN" OREGON. 139 

OWENS RIVER BASIN.

Owens River rises in the Sierra Nevada in eastern California and 

flows southeastward parallel with this range, finally discharging its 

waters into Owens Lake. Its basin, which lies between the Sierra 

Nevada on the west and the White Mountains on the east, has a 

length from north to south of approximately 150 miles and a width of 

from 20 to 25 miles. Practically the entire flow of the river is 

derived from the Sierra Nevada, as it drains the eastern slope of this 

range from Mount Lyell on the north to a point some distance 

below Mount Whitney on the south.

The results of data collected in the Owens River valley in 1907-8 

are contained in Water Supply Paper 251, which presents the results 

of all river discharge data collected in California during 1907-8.

GREAT BASIN DRAINAGE AREA IN OREGON.

DESCRIPTION.

The Great Basin drainage area in Oregon comprises about onefourth of the State. The surface waters throughout this area drain 

into the natural depressions in the ground, the water either evaporating or, if the flow is sufficient, forming perennial lakes. The area 

is generally high and rolling. Forests, except on the borders of the 

basin, are small. The soil is rough, sparsely covered with grass, and 

is given largely to range for sheep and cattle. The rainfall throughout the basin is about 10 inches per annum.

The principal lakes are Harney, Maineur, Warner, Summer, Silver, 

Christmas, Goose, and Abert. With the exception of Silver Lake 

all are alkaline. The surface waters of this basin are very valuable 

for irrigation, but unfortunately are insufficient in quantity. The 

irrigated valley lands contiguous to the streams have been taken, and 

the low-water flow of the principal streams is entirely used.

The general elevation of the Great Basin in Oregon is between 

4,000 and 5,000 feet. The ridges of mountains which form the rim of 

this basin have an approximate elevation of 7,000 feet. At Burns the 

elevation is 4,185; Silver Lake post-office, 4,380; Lake Abert, 4,209; 

and Warner Lake, 4,544.

Irrigation is almost an absolute necessity for growing anything 

except the hardier wheats, which have been raised with more or less 

success by the dry-farming process. Any extensive irrigation development will necessitate the investment of large sums of money in 

storage reservoirs and canal systems.

The principal streams of this basin, classified by the lakes into 

which they flow, are as follows: Silvies River, discharging into 

Malheur Lake; Donner and Blitzen River, draining the western slope
140 SURFACE WATER SUPPLY, 1907-8.

of Steins Mountain and flowing north into Malheur Lake; Silver Creek 

into Harney Lake; Silver, Bridge, and Bear creeks into Silver Lake; 

Summer Creek and Ana River into Summer Lake; and Chewaucan 

River into Lake Abert.

Silver Creek, in Lake County, drains the divide between the Great 

Basin and Klamath River drainage, flowing northward into Paulina 

Marsh and thence into Silver Lake, from which at high stages it overflows onto the Silver Lake Desert. From the same divide Bear Creek 

and Bridge Creek flow into Paulina Marsh. Ana River is a small 

stream, about 1^ miles long, which empties into Summer Lake, a 

strongly alkaline body of water. The waters of Ana River are warm 

and of excellent quality, as they come from subterranean depths 

through five large springs. The temperature of the water winter and 

summer is about 62° and the combined flow of the springs is about 

145 second-feet. Chewaucan River rises on the opposite side of the 

divide from Sprague River and flows north through Chewaucan Marsh 

into Lake Abert.

The following gaging stations have been maintained in this drainage 

basin:

Silvies River near Burns, Oreg., 1903-1906 and 1908.

Silvies River near Silvies, Oreg., 1903-1905.

Silver Creek (Harney County) near Riley, Oreg., 1904-1906 and 1908.

Silver Creek (Lake County) near Silver Lake, Oreg., 1904-1907.

Bridge Creek near Silver Lake, Oreg., 1905-6.

Bear Creek near Silver Lake, Oreg., 1905-6.

Ana River near Summer Lake, Oreg., 1905.

Chewaucan River near Paisley, Oreg., 1905-1907.

In addition to these gaging stations, a few records of lake heights 

have been kept in Silver Lake, Summer Lake, Harney Lake, and 

Malheur Lake. For several of these stations, which were reestablished the latter part of December, 1908, the data are withheld until 

the 1909 report.

SILVER CREEK NEAR SILVER LAKE, OREG.

> This station, which is located H miles southwest of Silver Lake 

post-office, 3 miles below the mouth of the West Fork of Silver Creek, 

in sec. 28, T. 28 N., R. 14 E., was established December 29, 1904, at 

the time the Silver Lake project was under investigation by the 

United States Reclamation Service. The present flow of the creek 

during the irrigating season is entirely appropriated for irrigation, 

and any additional development will involve the construction of 

storage reservoirs.

Ice interferes with the observations during the winter months. 

The conditions at the station, however, are favorable for good results 

during the open season. Owing to lack of funds the station was
GEEAT BASIN DRAINAGE AREA IN OREGON. 141

abandoned March 31, 1907, but observations were again resumed 

January 11, 1909. No measurements were made during 1907.

CHEWAUCAX RIVER AT PAISLEY, OREG.

This station, which was established January 4, 1905, is one-half 

mile above Paisley, 500 feet above Conn's mill ditch. George Conn's 

irrigation ditch diverts water from the left bank of the stream 2^ 

miles above the gaging station.

The results are of considerable value in connection with irrigation 

projects. The Chewaucan project was under investigation by the 

United States Reclamation Service in 1904 and 1905, but the data 

concerning the water supply were insufficient and construction has 

not yet been authorized. Since that time the State has entered into 

contract with private parties for the reclamation of about 12,000 

acres to the north and west of Paisley. Owing to the inaccessibility 

of the station and the lack of funds the station was abandoned December 10, 1907, but observations were again resumed January 17, 1909.

The conditions at the station are favorable for good results during 

the open season. The channel is not stable during floods, and the 

high waters during April, 1907, so modified the channel that the old 

rating curve was not applicable and no estimates have been possible 

since that date. No measurements were made during 1907.
