SURFACE WATER SUPPLY OF SNAKE RIVER BASIN, 1959

SCOPE OF WORK

This volume is one of a series of 20 reports presenting records of stage, discharge, 

and content of streams, lakes, and reservoirs in the United States during the 1959 water 

year. Since 1888, when the United States Geological Survey first studied streamflow in 

relation to problems of irrigation, similar records have been obtained at more than 

15,200 gaging stations in the 50 States. On September 30, 1959, the Geological Survey 

and cooperating organisations were maintaining 7,110 gaging stations. Partial-record 

stations for low flow or for flood flow have been operated at many other points. In 

addition, discharge measurements are made at miscellaneous sites. The records for the 

1959 water year at gaging stations, partial-record stations, and miscellaneous sites in 

the Snake River basin are given in this report.

COOPERATION

Many State, municipal, and private organizations have cooperated with the Geological 

Survey in this work by either furnishing or helping to collect data. Organizations that 

supplied data are acknowledged in station descriptions, and organizations that assisted 

in the collection of data through cooperative agreements with the Survey are:

Idaho: Idaho Department of Reclamation, G. N. Carter, State reclamation engineer; 

Idaho State Fish and Game Commission, Ross Leonard, , director.

Nevada: Department of Conservation and Natural Resources, H. A. Shamberger, 

director, and office of State Engineer, Edmund Muth.

Oregon: Office of the State Engineer, L. A. Stanley, and State Highway Commission, M. K. Mclver, chairman.

Utah: Office of the State Engineer, W. D. Criddle.

Washington: State Department of Conservation, Earl Coe, director, through Division of Water Resources, M. G. Walker, supervisor.

Wyoming: Office of the State Engineer, Earl Lloyd.

Assistance in the form of funds or services was given by the Corps of Engineers, 

Department of the Army, in collecting records published herein for 19 gaging stations, 

of which 13 were in Idaho, 2 in Oregon, 2 in Washington, and 2 in Wyoming.

Assistance was also furnished by the Forest Service of the Department of Agriculture; 

by the Bonneville Power Administration, and the Bureau of Reclamation of the United States 

Department of the Interior; and by the Atomic Energy Commission. 

The following organizations aided in collecting records:

Idaho: Board of Control for Boise Project, Idaho Power Co., Idaho Water 

District 36, North Side Canal Co., Twin Falls Canal Co., Utah Power & Light Co., 

Washington Water Power Co., Pacific Northwest Power Co., American Falls Reservoir 

District 2, and watermasters for Big Lost, Little Lost, Bid Wood, Little Wcod, 

Boise, and Lake Fork Payette Rivers, and Mud Lake.

Information of a more detailed nature than that published for most of the gaging stations given in this report Is on file in the district offices listed above. Provisional 

records of discharge prior to publication, and other unpublished data concerning the 

gaging-station records may generally be obtained from the district office.

DEFINITION OF TERMS AND ABBREVIATIONS

The terms of streamflow and other hydrologic data, as used in this report, are defined 

as follows:

Gaging station is a particular site on a stream, canal, lake, or reservoir where 

systematic observations of gage height or discharge are obtained. When used in connection with a discharge record, the term is applied herein only to those gaging stations 

where a continuous record of discharge is obtained.

Partial-record station is a particular site where limited stream-flow data are collected systematically over a period of years for use in hydrologic analyses.

Cubic foot per second (cfs) is the rate of discharge of a stream whose channel is 

1 square foot in cross-sectional area and whose average velocity is 1 foot per second.

Cubic feet per second per square mile (cfsm) is the average number of cubic feet of 

water flowing per second from each square mile of area drained, assuming that the runoff 

is distributed uniformly in time and area.

Runoff in inches (in.) shows the depth to which the drainage area would be covered if 

all the runoff for a given time period were uniformly distributed on it.

Acre-foot (ac-ft) is the quantity of water required to cover an acre to the depth of 

1 foot and is equivalent to 43,560 cubic feet.

Cfs-day is the volume of water represented by a flow of 1 cubic foot per second for 

24 hours. It is equivalent to 86.4UO cubic feet, 1.983471 acre-feet, or 646,317 gallons, 

and represents a runoff of 0.0372 inch from 1 square mile.

Stage-discharge relation is the relation between gage height and the amount uf water 

flowing in a channel, expressed as volume per unit of time.

Control designates a feature downstream from the gage that determines the stagedischarge relation at the gage. This feature may be a natural constriction of the channel, a long reach of the channel, or an artificial structure.

Contents is the volume of water in a reservoir. Unless otherwise indicated, volume is 

computed on the basis of a level pool and does not Include bank storage.

The drainage area of a stream at a specified location is that area, measured in a horizontal plane, which is so enclosed by a topographic divide that direct surface runoff 

from precipitation normally would drain by gravity into the river above the specified 

point. Figures of drainage area given herein include all closed basins, or noncontributing areas, within the area unless otherwise noted.

DOWNSTREAM ORDER AND STATION NUMBERS

Beginning with the series of reports for the water year ending September 30, 1951, the 

order of listing gaging-station records was changed. In this report, in a downstream 

direction along the main stem, all stations on a tributary entering above a main-stem station are listed before that station. If a tributary enters between two main-stem stations, it is listed between them. A similar order is followed in listing stations on 

first rank, second rank, and other ranks of tributaries. To indicate the rank of any 

tributary on which a gaging station is situated and the stream to which it is immediately 

tributary, each indention in the listing of gaging stations in the table of contents of 

this report represents one rank. This downstream order and system of idention show 

which gaging stations are on tributaries between any two stations on a main steii and the 

rank of the tributary on which each gaging station is situated.

The order of listing used before the publication of the 1951 report listed first all 

stations on the main stem from headwaters toward mouth, then all stations on the uppermost tributary to the main stem from the tributary's source to mouth, and then all stations from source to mouth of the uppermost tributary to the tributary.

As an added means of identification, each gaging station and partial-record station 

has been assigned a station number. The numbers have been assigned in the same downstream order used in this report. In assigning station numbers, no distinctior is made 

between partial-record stations and regular gaging stations, so that the station number 

for a partial-record station indicates downstream-order position in a list made up of 

both types of stations. Gaps are left in the numbers to allow for new stations that may 

be established; hence the numbers are not consecutive. The complete number for each 

station includes the part number, but the station number shown in this report, just to 

the left of the station name, consists of only the essential digits of the complete number. For example, for a station with the complete number 13-0100.00, the station number 

shown in this report is 100. The notation to the left of the hyphen is the part number; 

it is 13 for all stations in this report and is therefore omitted.

EXPLANATION OF DATA

The base data collected at gaging stations consist of records of stage and measurements of discharge. In addition, observations of factors affecting the stage-discharge 

relation, weather records, and other information are used to supplement base data in 

determining the daily flow. The records of stage are obtained either from direct readings on a nonrecording gage or from a water-stage recorder that gives a continuous record
4 SURFACE WATER SUPPLY, 1959, PART 13

of fluctuations. Measurements of discharge are made with a current meter by the general 

methods adopted by the Geological Survey on the basis of experience in stream gaging 

since 1888. These methods are described in Water-Supply Paper 888 and are also outlined 

in standard textbooks on the measurement of stream discharge.

Rating tables giving the discharge for any stage are prepared from stage-discharge 

relation curves defined by discharge measurements. If extensions to the rating curves 

are necessary to define the extremes of discharge, they are made on the basis of indirect 

measurements of peak discharge (such as slope-area or contracted-opening measurements,, 

computation of flow over dams or weirs, and by other methods), velocity-area studies, and 

logarithmic plotting. The application of the daily mean gage height to those rating 

tables gives the daily mean discharge, from which the monthly and the yearly mean discharge are computed. If the stage-discharge relation is subject to change because of 

frequent or continual change in the physical features that form the control, the daily 

mean discharge is determined by the shifting-control method, in which correction factors 

based on individual discharge measurements and notes by engineers and observers are used 

in applying the gage heights to the rating tables. If the stage-discharge relation for 

a station is temporarily changed by the presence of aquatic growth or debris on the control, the daily mean discharge is computed by what is essentially the shifting-control 

method.

At some gaging stations the stage-discharge relation is affected by backwater from 

reservoirs, tributary streams, or other sources. This necessitates the use of the slope 

method in which the slope or fall in a reach of the stream is a factor in determining 

discharge. Information requisite for determining the slope or fall is obtained by means 

of an auxiliary gage set at some distance from the base gage. At some stations the 

stage-discharge relation is affected by changing stage. If so, the rate of change in 

stage is used as a factor in the determination of discharge.

At most gaging stations in the northern part of the United States and at some in the 

mountainous regions of other parts the stage-discharge relation is affected by ice during 

the winter, and it becomes impossible to compute the discharge in the usual manner. Discharge for periods of ice effect is computed on the basis of the gage-height record and 

occasional winter discharge measurements, consideration being given to the available 

information on temperature and precipitation, notes by gage observers ani engineers, and 

comparable records of discharge for other stations in the same or nearby basins. If the 

stage-discharge relation is affected by ice, this information is given in a note to the 

table. No mention is made of occasional days of ice effect if the degree of accuracy of 

daily records is not changed.

The data herein presented generally comprise a description of the station, a skeleton 

rating table, and a table showing the daily discharge and monthly and yearly discharge 

of the stream. Records are published for the water year which begins on October 1 and 

ends on September 30. A calendar for the water year 1959 is shown on Page IV for the 

purpose of finding the day of the week for any date.

The description of the station gives the location, drainage area, records available, 

type and history of gages, average discharge, extremes of discharge, general remarks, and 

notations of revisions of the previously published record. The location of the gaging
EXPLANATION OF DATA 5

station and the drainage area are obtained from the most accurate maps available. River 

mileage, given under "Location" for some stations, is that determined and used by the 

Corps of Engineers unless other-wise noted. Under "Records available" are given the 

periods for which there are published records generally equivalent to those at the present site. Under "Gage" are given the type of gage currently in use and the datum of the 

present gage above mean sea level, and a condensed history of the types, locations, and 

daturas of previous gages used during the period of records available. Under "Average 

discharge" is given the average discharge for the number of years indicated. It is not 

given for stations having fewer than five complete years of record or for stations where 

changes in water development during the period of record cause the figure to have little 

significance. Under "Extremes" are given the maximum discharge and gage height; the minimum discharge if there is little or no regulation; the minimum daily discharge if there 

is extensive regulation (also the minimum discharge if useful); and the minimuir gage 

height (unless it is of no importance). In the first paragraph, the data giver are for 

the complete current water year unless otherwise specified. In the second paragraph, 

the data given are for the periods of record within the calendar year dates in the heading (not necessarily those for the complete years indicated by .the heading dates). 

Reliable information concerning major floods that have occurred outside the period of 

record are given in the third or last paragraph under "Extremes." Unless other-vise qualified, the maximum discharge corresponds to the crest stage obtained by use of a waterstage recorder, a crest-stage indicator, or a non-recording gage read at the tine of the 

crest. If the maximum gage height did not occur at the same time as the maximum discharge, it is given separately. Information pertaining to the accuracy of the records 

and conditions which affect the natural flow at the gaging station is given under 

"Remarks."

Previously published records of some stations have been found to be in error on the 

basis of data or information later obtained. Revisions of such records are usually published along with the current records in one of the annual reports. In order to make it 

easier to find such revised records, a paragraph headed "Revisions (water years)" has 

been added to the description of all stations for which revised records have b3en published. Listed therein are all-reports in which revisions have been published, each 

followed by the water years for which figures are revised in that report. In listing the 

water years only one number is given; for instance, 1933 stands for the water year October 1, 1932, to September 30, 1933. If no daily, monthly, or annual figures of discharge 

are concerned in the revisions, that fact is brought out by notations after the year 

dates as follows: "(M)" means tbat only the instantaneous maximum discharge vras revised; 

"(m)" that only the instantaneous minimum was revised; and "(P)" that only peak discharges were revised. If the drainage area has been revised, the report in which the 

revised figure was first published is given. It should be noted that for all stations 

for which cubic feet per second per square mile and runoff in inches are published, a 

revision of the drainage area necessitates corresponding revision of all figures based on 

the drainage area. Revised figures of cubic feet per second per square mile end runoff 

in inches resulting from a revision of the drainage area only are usually not published 

in the annual series of reports.
6 SURFACE WATER SUPPLY, 1959, PART 13

Skeleton rating tables are published for all stations except those at which the dally 

discharge for the greater part of the open-water period was determined ty the shiftingcontrol method, the slope method, or other special methods involving an equivalent adjustment to the gage height of more than one-tenth foot. Skeleton rating tables are generally 

not published for stations on canals.

For stations equipped with water-stage recorders, except those on streams subject to 

sudden or rapid fluctuation, the daily table gives the discharge corresponding to the 

daily mean gage height. For stations subject to such fluctuation the daily mean gage 

height may not indicate the true daily mean discharge, which must be obtained by averaging the discharge for parts of the day or by using the discharge integrator, an instrument for obtaining the daily mean discharge from a continuous gage-height graph and containing, as an essential element, a curve representing the stage-discharge relation at 

the station. For stations equipped with nonrecording gages, the table of daily discharge 

gives the discharge corresponding to once-daily readings of the gage, or to the mean of 

twice-daily readings, or to the mean gage height determined from gage-height graphs based 

on gage readings. For periods of rapidly changing stage, the daily mean discharge is 

determined from gage-height graphs based on gage readings, the frequency of which is 

stated in the station description.

In the table of daily discharge, the figures for the maximum day and the minimum day 

for each month are underlined. If the figure is repeated, it is underlined only on the 

first day of its occurrence.

In the monthly summary below the daily table, the line headed "Total" gives the sum of 

the daily figures; it is the total cfs-days for the month. The line headed "Mean" gives 

the average flow in cubic feet per second during the month. Discharge for the month may 

be expressed in cubic feet per second per square mile (line headed "Cfsm"), or in inches 

(line headed "In."), or in acre-feet (line headed "Ac-ft"). Figures for cubic feet per 

second per square mile and runoff in inches are omitted if the drainage area -includes 

large noneontributing areas, or if the average annual rainfall over the drainage basin is 

usually less than 20 inches.

In the yearly summary below the monthly summary, the figures of maximum are the maximum daily discharges, not the momentary discharge when the water was at crest stage. 

Likewise, the minimums in this summary are the minimum daily discharges.

Peak discharges and the times of their occurrence and corresponding gfge heights of 

most stations are listed below the table of daily and monthly discharge. All independent 

peaks above the selected base are given. The base discharge, which is given in parentheses, is selected so that an average of about three peaks a year will be presented. Peak 

discharges are not published for canals, ditches, drains, or for any stream for which the 

peaks are subject to substantial control by man.

Footnotes to the table of daily discharge indicate periods when discharge was computed 

or estimated by unusual or special methods during periods of no gage-height record and 

Ice effect, or by other effects that reduce the degree of accuracy of the records. Days 

on which discharge measurements were made are indicated by asterisk and footnote unless 

they were made at frequent regular intervals, in which instance the general frequency of 

discharge measurements is given under "Remarks" in the station description.
ACCURACY OF FIKLD DATA AND COMPUTED RESULTS 7

For most gaging stations on lakes and reservoirs the data presented comprise a 

description of the station and a monthly summary table of stage and contents. For some 

reservoirs a table showing daily contents or stage is given. A skeleton table of capacity 

at given stages is published each year for all reservoirs for which records are published 

on a daily basis, but is not published for reservoirs for* which only monthly data are 

given.

At many gaging stations water samples are collected from the streams for the purpose 

of making chemical analyses, computing dissolved solids, suspended sediment loads, and 

particle-size distribution, or measuring water temperatures. For most of these samples 

the results are published in an annual series of water-supply papers entitled "Quality of 

Surface Waters of the United States" which is issued in four volumes. In this report 

under "Remarks" a reference is made to quality-of-water records collected at gaging stations on a regular basis and published in the quality-of-water reports. At many other 

gaging stations quality-of-water data are obtained at irregular intervals and published 

as "miscellaneous analyses" in quality-of-water reports; such records are not referred to 

in "Remarks" paragraph in this report. At many gaging stations water temperatire is 

obtained also at the time a discharge measurement is made; such temperature readings are 

not reported in the quality-of-water annual reports.

Data collected at partial-record stations and at miscellaneous sites are given at the 

end of each report. Partial-record stations are presented in two tables. The first is 

a table of discharge measurements at low-flow partial-record stations, and the second is 

a table of annual maximum stage and discharge at crest-stage stations. Discharge measurements at miscellaneous sites are given in a third table. Occasionally, a series of 

discharge measurements are made within a short time period to investigate the seepage 

gains or losses along a reach of a stream or to determine the low-flow characteristics of 

an area. Such measurements are given in special tables after the list of measurements at 

miscellaneous sites.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of streamflow data depends primarily on (1) the stability of fie stagedischarge relation or, if the control is unstable, the frequency of discharge measurements, and (2) the accuracy of observations of stage, measurements of discharge, and 

interpretation of records.

The station description states the degree of accuracy of the records. "Excellent" 

indicates that, in general, the error in the daily records is believed to be less than 

5 percent; "good," less than 10 percent; "fair," less than 15 percent; and "poor," probably more than 15 percent. The records of monthly and yearly mean discharge and runoff 

are, in general, more nearly accurate than the daily records.

Discharge at some stations, as indicated by the monthly mean, may vary widely from 

natural runoff, owing to diversion, consumption, regulation by storage, increase or 

decrease in evaporation due to artificial causes, or to other factors. For suih stations, 

figures of cubic feet per second per square mile and of runoff in inches are not published unless satisfactory adjustments can be made for diversions, for changes in contents 

of reservoirs, or for other changes incident to use and control. Evaporation from a

564834 O - 60 -2
8 SURFACE WATER SUPPLY, 1959, PART 13

reservoir is not included in the adjustments for changes in reservoir contents, unless 

it is so stated. Even at those stations where adjustments are made, large errors in 

computed runoff may occur when relatively large negative adjustments are made or when 

evaporation is large in comparison with the observed discharge.

Many gaging stations on streams in the irrigated areas of the United States are situated above most of the diversions from those streams, and therefore the discharge recorded 

does not actually show the water supply available at the stations for further development, 

because water must first be supplied to existing irrigation systems.

PUBLICATIONS

Basic data for gaging stations are published in an annual series of reports consisting 

of 20 volumes, including one each for the States of Alaska and Hawaii. Tl-e area of the 

other 48 States is divided into 14 parts whose boundaries coincide with certain natural 

drainage lines. Formerly, the annual series of reports on surface-water eupply consisted 

of 14 volumes, one for each of the 14 parts. Beginning with the reports for 1951, the 

records for the 48 States were published in 18 volumes, there being 2 volumes each for

Note. Records for all stations in Oregon through September 1910 are contained in WSP 370, superseding" all earlier reports for these stations.

A compilation of records for the area covered by this report through September 1950 has 

been published as Water-Supply Paper 1317. That report contains a summary of monthly and 

annual discharges for all previously published records as well as some records not contained in the annual series of water-supply papers. All records were reeyajnined and 

revised where waoranted. Estimates of discharge were made to fill short gaps whenever 

practical.

The reports listed in the foregoing tables contain the customary records of discharge 

collected during the systematic operation of gaging stations. Detailed irformation on 

the stage and discharge of many streams during major floods has been included in special 

reports on these floods published by the Geological Survey!. The more recent of these

HYDROLOGIC CONDITIONS

Runoff for the water year was generally excessive in the northern part of the basin, 

near median in the central part, and deficient in the southern part. Delayed srownelt 

and above average temperatures caused excessive runoff during June in most of tte basin. 

Runoff for September, caused by unseasonal rains, exceeded previous flows of record for 

the month in several tributaries and was near the maximum of record in others. .Cloudbursts In the hills north and northeast of Boise on August 20 caused floods in several 

small tributaries. Discharges per square mile at the crest of the floods were IT far 

the highest ever measured in that part of Snake River basin. Drought conditions again 

returned to the southern tributaries of Snake River. Annual runoff of the Owyhee River 

near Gold Creek, Nevada, was the lowest in 31 years of record and only 24 percent of 

median.

the capacity was further increased to 847,000 acre-ft between gage heights 6,730 (top 

of baffles to sluices) and 6,769 ft (top of spillway gates). Water is used for irrigation in Snake River Valley, Idaho. Figures given herein represent usable contents.

HENRYS FORK BASIN 29 

420. Island Park Reservoir near Island Park, Idaho

Location. Lat 44°25'11", long 111°23'52", a quarter of a mile south of quarter corner 

between sees. 28 and 29, T.13 N., R.43 E., in gatehouse shaft at dam on Henrys Fork, 

three-eighths of a mile upstream from Buffalo River and 2 miles west of Island Park 

Post Office.

Drainage area. 481 sq mi.

Records available. November 1938 to September 1959.

Gage. Electric-tape gage read once daily. Datum of gage is at mean sea level (levels by 

Bureau of Reclamation).

Extremes. Maximum contents during year, 137,395 acre-ft May 3 (elevation, 6,303.27 ft); 

 minimum, 16,790 acre-ft Oct. 13 (elevation, 6,274.17 ft).

1938-59: Maximum contents, 140,515 acre-ft May 13, 1957 (elevation, 6,303.65 ft); 

minimum after first filling of reservoir in May 1939, that of Oct. 13, 1958.

Remarks. Reservoir is formed by earth-fill rock-faced dam. Storage began Nov. 15, 1938. 

Capacity, 127,265 acre-ft between elevations 6,239 (normal low-water level with outlet 

gates open) and 6,302 ft (crest of spillway). Natural flow passing through reservoir 

when outlet gates are open limits withdrawal of storage to elevation 6,230 ft (sill of 

lower outlet). Dead storage negligible. Water is used for irrigation of lands in 

Fremont-Madison irrigation district between Ashton and Rexburg. Figures given herein 

represent usable contents.

Cooperation. Reservoir elevations and capacity table furnished by Bureau of Reclamation.

42 BLACKFOOT RIVER BASIN

685. Blackfoot River near Blackfoot, Idaho

Location. Lat 43°07'50", long 112°28'35", at east quarter corner of sei.28, T.3 S., 

R.34 E., on left bank 125 ft downstream from highway bridge, 2 miles upstream from 

mouth, and 8 miles southwest of Blackfoot.

Drainage area.--1.395 sq mi, including that of Sand Creek whose flow is diverted to Blackfooc River through the Idaho canal.

Records available. July 1913 to September 1959 (prior to October 1931, summer months 

only).Monthly discharge only for some periods, published in WSP 1317.

Gage.--Water-stage recorder. Altitude of gage is 4,420 ft (from river-proflie survey). 

Prior to May 8, 1926, staff gages and May 8, 1926, to June 25, 1937, water-stage 

recorder, at site half a mile upstream at different datum.

Average discharge. 28 years (1931-59), 153 cfs (110,800 acre-ft per year).

Extremes.--Maximum discharge during year, 1,010 cfs Apr. 4 (gage height, 6.22 ft); no flow 

June 10-13, July 28-30.

1913-59: Maximum discharge, 1,040 cfs May 26, 1957 (gage height, 7.04 ft); no flow 

for many days. At time of peak flow about 1,300 cfs was being lost above station to 

 canal diversions and percolation.

Remarks.--Records good except those for periods of ice effect, which ar? poor, and those 

for periods of no gage-height record and discharges below 20 cfs, which are fair. 

Flow regulated by Blackfoot-Marsh Reservoir (capacity at spillway crest, 312,000 acreft, and maximum capacity with flashboards, 413,000 acre-ft). Many diversions above 

station for irrigation. Most of flow during nonirrigation season and part of that 

during irrigation season is supplied by waste from Snake River canals.

Cooperation. Gage-height record furnished by Office of Indian Affairs. 

Revisions. WSP 1217: Drainage area.

Rating table, water year 1958-59, except periods of ice effect (gage

height, in feet, and discharge, in cubic feet per second)

Tug. 29, 1912, at site 200 ft downstream at different datum.

Average discharge.--45 years, 45.2 cfs (32,720 acre-ft per year).

Extremes.--Maximum discharge during year, 89 cfs Apr. 7 (gage height, 2.58 ft); minimum, 

0.9 cfs Aug. 17 (gage height, 1.07 ft).

1911-16, 1919-59: Maximum discharge, 1,670 cfs Jan. 23 or Feb. 24, 1943 (gage 

height, 7.6 ft, from floodmark), from rating curve extended above 600 cfs by logarithmic plotting; no flow July 22 to Aug. 10, Aug. 22-30, 1934, Aug. 15 to Oct. 3, 

1935, July 22 to Sept. 25, 1940, Sept. 14, 1947.

Remarks. Records excellent except those for periods of ice effect, which are fsir.

Decreed water rights are reported to apply to about 2,700 acres above station. Diversions for irrigation are made as flow permits to a major part of this acreage. Flow 

of artesian well, completed in 1935, enters below station. Practically entire flow 

passing station is stored in Oakley Reservoir (see p. 61).

Records available. May 1911 to September 1916, March 1919 to September 1959. Monthly 

discharge only for some periods, published in WSP 1317.

Gage. Water-stage recorder and concrete control. Altitude of gage is 4,820 ft (by 

Farometer). Prior to Sept. 1, 1912, water-stage recorder at approximately present 

site at different datum. Sept. 1-30, 1912, staff gage at site three-quarters of a 

mile downstream at different datum. Apr. 8, 1913, to Sept. 30, 1916, and Mar. 28, 

1919, to Aug. 15, 1931, water-stage recorder at site 1 mile upstream from present site 

at different datum.

Average discharge. 45 years, 14.7 cfs (10,640 acre-ft per year).

3.6 cfs Nov. 17 (gage height, 4.64 ft).

1911-16, 1919-59: Maximum discharge recorded, 270 cfs Aug. 17, 1941 (gage height, 

6.99 ft), from rating curve extended above 100 cfs on basis of velocity-area studies 

and peak flow over weir (a higher flow may have occurred Aug. 15, 1931); minimum 

recorded, 2.3 cfs Feb. 22, 1949, result of freezeup.

Remarks. Records good except those for period of no gage-height record, which are fair. 

A few small diversions above station. Flow of artesian well, completed in 1936, enters 

above. Practically entire flow passing station is stored in Oakley Reservoir.

1150. Mud Lake near Terreton, Idaho

Location. Lat 43°54', long 112°21 I , in ME^SE^ sec.32, T.7 N., R.35 E., 670 ft north of 

mouth of Camas Creek, 4.4 miles northeast of First Owsley pumphouse, and 5? miles northeast of Terreton.

Drainage area. 1,130 sq mi, approximately, not including Medicine Lodge Creek.

Records available.--April 1921 to September 1959.

Gage.--Water-stage recorder. Datum of gage is 4,774.99 ft above mean sea level, unad- 

;fusted. Prior to Oct. 31, 1931, staff gages at or near pumphouse (now used as supplementary gage) at same datum. Oct. 31, 1931, to Sept. 30, 1954, water-stage reiorder at 

site 2.7 miles southwest and 2 miles north of First Owsley pumphouse at same datum.

Extremes.--Maximum contents during year, 22,900 acre-ft Apr. 23, 24, 26; maximum gage

height, 5.64 ft Apr. 22, 24 (affected by wind); minimum contents, 3,500 acre-f; Aug. 13 

(gage height, 0.05 ft).

1921-59: Maximum contents observed, 61,660 acre-ft May 5, 1923 (gage height, 

9.20 ft); practically no contents Oct. 1 to Nov. 15, 1937, due to bypassing Canas Creek 

(see Remarks).

Remarks. Mud Lake is a perched body of water confined by earth dikes and fed by ground 

water and surface tributaries augmented by well flows and surface inflow from North 

Lake. For complete description of Mud Lake region, see WSP 818. Water for irrigation 

is diverted for lake by pumping. During low-lake stages, inflow from Camas Creek may 

be bypassed through Camas Creek diversion canal directly to lake outlet channel leading 

to First Owsley pumping plant. Bypass was not used during 1959. Other irrigation 

diversions are made by various means from adjacent lakes and wells and Camas C-eek 

above lake. Area of Mud Lake is varied from time to time by changes in dikes. Figures

f

iven herein represent contents above gage height -4.0 ft. Capacity table prepared 

rom surveys made by Geological Survey and adjusted for changes in dikes. High winds 

are frequent, and stage at recorder during wind doas not usually represent the mean for 

the lake. 

Cooperation. Water-stage recorder inspected by employees of Water District No. 63 and

supplemental staff-gage readings furnished by Owsley Canal Co. 

Revisions. WSP 1567: Drainage area.

MUD LAKE-LOST RIVER BASINS 99

1260. Mackay Reservoir near Mackay, Idaho

Location. Lat 43°57', long 113"40' , in sec.12, T.7 N., R.23 E., on headgate toi-er of dam 

on Big Lost River, 4 miles northwest of Mackay.

Drainage area.--783 sq mi.

Records available.--January 1919 to September 1959.

Gage. Staff gage read once daily. Datum of gage is 6,000 ft above mean sea level, Utah 

Construction Co. datum, or about 6,001.2 ft above mean sea level, unadjusted.

Extremes.--Maximum contents observed during year, 35,530 acre-ft Apr. 20 (gage height, 

59.70 ft); minimum observed, 232 acre-ft Sept. 13, 14 (gage height, 8.35 ft).

1919-59: Maximum contents observed, 44,710 acre-ft June 28, 1957 (gage height, 

66.75 ft); no available contents during periods in 1919-20, 1924, 1926, 1929, 1931-35; 

minimum gage height observed, 6.3 ft Aug. 5, 1934.

Remarks. Reservoir is formed by earth- and rock-fill dam, which was reconstructed in 

1917-18; storage impounded by original dam not recorded. Crest of spillway was raised 

5 ft in September 1956. Capacity is 44,370 acre-ft between gage heights 7.0 and 

66.5 ft (crest of spillway). Dead storage reported to be about 125 acre-ft. Water is 

used for irrigation of about 33,000 acres in Big Lost River irrigation district. About 

9,000 acres irrigated from Big Lost River and tributaries above reservoir. Considerable seepage around dam because of its porous foundation, but the greater part of this 

water returns to Big Lost River between reservoir and station below reservoir, near 

Mackay. Figures given herein represent usable contents.

Cooperation. Gage readings and capacity table furnished by Water District No. 27.

Flow at this station plus flow of Brailsford ditch (see preceding page) gives total 

flow from Riley and Lewis Springs plus small intervening inflow. Flow diverted from 

Lewis Spring to Brailsford ditch for irrigation. Slight regulatior by ponds at fish 

hatchery. Beginning about Aug. 30, 1957, water was diverted from Hickel Spring to 

Riley Creek above station.

Correction.--Monthly and yearly figures for water year 1957-58 adjusted for diversion in 

Brailsford ditch should read adjusted for inflow from Bickel Spring.

120 MALAD RIVER BASIN

1510. Little Wood River near Richfield, Idaho

Location.--Lat 43°03', long 114°08' , in sec.30, T.4 S., R.20 E., on right bank half a 

mile upstream from Byrns Slough and heading of Dietrich Canal, 1 mile east of railroad 

station at Richfield, and 14 miles downstream from Silver Creek.

Drainage area. 570 sq mi, approximately.

Records available. January 1911 to September 1959 (irrigation seasons only prior to 1955 

except 1913 , 1921).

Gage. Water-stage recorder. Altitude of gage is 4,270 ft (by barometer). Prior to 

Sept. 5, 1918, staff gage at site 500 ft downstream at datum 0.92 ft lower. Sept. 5, 

1918, to Apr. 13, 1920, staff gage and Apr. 14, 1920, to May 20, 1954, water-stage 

recorder, at site 500 ft downstream at datum 0.08 ft higher than present datum.

Average discharge.--7 years (1912-13, 1920-21, 1954-59), 155 cfs (112,200 acre-ft per 

year).

Extremes. Maximum discharge during year, 304 cfs Nov. 11 (gage height, 3.65 ft); maximum 

gage height, 3.94 ft Jan. 8 (ice Jam); minimum discharge, 56 cfs June 10; minimum gage 

height, 2.16 ft Aug. 18.

1911-59: Maximum discharge recorded, 868 cfs May 3, 1938 (gage height, 3.97 ft, 

site and datum then in use); maximum gage height recorded, 8.60 ft Feb. 21, 1956 (ice 

Jam); minimum discharge recorded, 7.6 cfs June 24, 25, 1920 (gage height, 0.52 ft, site 

and datum then in use).

Remarks. Records good except those for periods of ice effect, which are fair. Diversions 

for irrigation of about 38,300 acres (1950 determination) above station. Flow partly 

regulated by Little Wood Reservoir (capacity, 12,180 acre-ft), Fish Creek Reservoir 

(capacity, 13,700 acre-ft), and three small reservoirs on tributaries (combined capacity, 690 acre-ft). River above Silver Creek is dry a large part of the time because 

of channel losses and irrigation diversions above Carey.

Rating table, water year 1958-59, except periods of loe effect (gage 

height, in feet, and discharge, in cubic feet per second)

MALAD RIVER BASIN 121

1515. Little Wood River at Shoshone, Idaho

Location.--Lat 42°56', long 114°24', in sec.2, T.6 S., R.17 E., on left bank Just upstream 

from dam used prior to 1955 for diversion of town water supply, 400 ft upstream from 

highway bridge in Shoshone.

Drainage area.--620 sq mi, approximately.

Records available.--April 1922 to September 1959 (irrigation seasons only prior to 1955).

Gage.--Water-stage recorder. Datum of gage is 3,956.99 ft above mean sea level, datum of 

T929, supplementary adjustment of 1947. Prior to Oct. 18, 1954, at datum 1.98 ft 

higher.

Extremes.--Maximum discharge during year, 535 cfs May 18 (gage height, 3.73 ft); minimum daily, 30 cfs Oct. 6-8.

1922-59: Maximum discharge recorded, 697 cfs May 13, 1958 (gage height, 4.78 ft); 

maximum gage height, 9.42 ft Feb. 27, 1957 (ice jam); no flow July 29, 1931, Cot. 3, 

1938.

Remarks. Records excellent except those for periods of ice effect, which are fair. Diversions for irrigation of about 52,200 acres (1950 determination) above station. Flow 

affected by operation of Milner-Gooding canal, which diverts from Snake River and 

crosses little Wood River above station, by operation of five reservoirs above Carey 

(see Remarks for station near Richfield), and by Big Wood River water deliveries 

through Byrns Slough to Dietrich Canal which diverts from left bank of Little Wood 

River at Richfield.

SNAKE RIVER MAIN STEM 125

1545. Snake River at King Hill, Idaho

Location. Lab 43°00'10", long 115°12'05" (revised), in SW^ sec.7, T.5 S., R.ll'E., on 

right bank 300 ft east of railroad station at King Hill and 20 miles downstream from 

Malad River.

Drainage area. 35,800 sq mi, approximately. 

Records available.--May 1909 to September 1959.

Gage. Water-stage recorder. Datum of gage is 2,492.3 ft above mean sea level, by stadia 

levels. May 13, 1909, to Mar. 1, 1910, staff gage on left bank at present site at 

datum 2.20 ft higher. Mar. 7 to Aug. 16, 1910, staff gage three-quarters of a mile 

upstream at different datura. Aug. 17, 1910, to Oct. 7, 1928, staff gage at present 

site and datum.

Extremes.--Maximum discharge during year, 16,400 cfs Oct. 16 (gage height, 8.96 ft); minimum, 1,990 cfs Dec. 3 (gage height, 2.60 ft); minimum daily, 6,700 cfs Dec. 3.

1909-59; Maximum discharge observed, 47,200 cfs June 22, 1918 (gage height, 16.3 ft), 

from rating curve extended above 30,000 cfs; minimum observed, 1,250 cfs Jan. 10, 1950 

(gage height, 1.75 ft); minimum daily, 4,760 cfs July 7-9, Aug. 15, 16, 1910.

Remarks. Records excellent. Flow regulated by powerplants at Lower Salmon Falls and near 

Bliss and by many reservoirs above station. Practically entire flow at Milner diverted 

at times during some irrigation seasons; flow at King Hill is then derived largely from 

springs and seepage entering below Milner. About 1,590,000 acres irrigated by diversion from river and its tributaries above station. Records of chemical analyses and 

water temperatures for the water year 1959 are given in WSP 1644.

of Reclamation).

Extremes.--Maximum contents observed during year, 939,400 acre-ft Apr. 6-8 (elevation, 

2,654.70 ft); minimum observed, 572,400 acre-ft Sept. 19 (elevation, 2,614.95 ft).

1932-59: Maximum contents observed, 1,140,000 acre-ft Apr. 15, 1S52 (elevation, 

2,671.40 ft); minimum observed since full capacity was attained on May 7, 1936, 

462,700 acre-ft Oct. 10, 1955 (elevation, 2,599.44 ft).

Remarks.--Reservoir is formed by concrete arch-gravity dam, completed in September 1932; 

storage began Oct. 16, 1932. Capacity, 1.122,000 acre-ft between elevations 2,367.5 

(bottom of sluice gates) and 2,670.0 ft (top of spillway gate), 715,000 acre-ft 

between elevations 2,590.2 (diversion tunnel) and 2,670.0 ft. Dead storage below 

elevation 2,367.5 ft negligible. Figures given herein are of contents above elevation 

2,367.5 ft. The reservoir will generally not be drawn below elevation 2,590.2 ft. 

Water is released through diversion tunnel to South Canal for irrigation of lands west 

of Snake River in vicinity of Homedale, Idaho, and to North Canal for irrigation of 

lands north and west of Owyhee River, and through sluice gates to river for Owyhee 

Canal, which diverts about 18 miles downstream.

BOISE RIVER BASIN 145

1940. Arrowrock Reservoir at Arrowrock, Idaho

Location. Lat 43°36', long 115°55', in E| sec.13, T.3 N., R.4 E., at dam on Boise River 

at Arrowrock, 14 miles east of Boise.

Drainage area. 2,210 sq mi, approximately. 

Records available. October 1917 to September 1959.

 £_. Staff gage graduated on face of dam read once daily, 

evel (levels by Bureau of Reclamation).

Datum of gage is at mean sea

Extremes. Maximum contents observed during year, 286,600 acre-ft June 24 (elevation, 

 3,216.0 ft); minimum observed, 1,250 acre-ft Sept. 18 (elevation, 3,001.0 ft).

1917-59: Maximum contents observed, 301,200 acre-ft May 29, 1948 (elevation,

3,219.1 ft); no usable contents during period in each of several years when sluice

gates were open and natural flow was passing through reservoir.

Remarks. Reservoir is formed by gravity-section concrete-arch dam completed in 1915 and 

raised 5 ft in 1937; storage began in 1915. Capacity, 286,600 acre-ft between elevations 2,974 (9.5 ft above sluice gate sill) and 3,216 ft (highest position of movable 

crest of spillway). Silt deposition at dam has raised the lower storage level and 

decreased the capacity of the reservoir. Prior to Oct. 1, 1952, contents in publications of the Geological Survey applied from original capacity table and no silt corrections were made. Beginning Oct. 1, 1952, contents applied from revised table, which is 

the original table reduced by amounts varying from 347 acre-ft at elevation 2,974 to 

5,000 acre-ft at elevation 3,085 ft and above. Water is used for irrigation in Boise 

Valley.

Cooperation.--Gage readings and capacity table furnished by Bureau of Reclamation.

Between near Boise and at Boise gaging stations (prior to 1955 water year, published 

as between Dowling Ranch and Boise gaging stations), six principal canals and several 

small farm laterals divert water from Boise River for irrigation.

Records of total diversion during period April to September for each canal for years 

1919-46, combined daily diversion covering period April to September fo~ years 1947-59 

and daily flow of New York Canal February 1939 to October 1948 in reports of Geological 

Survey. Records of daily diversion for each canal from 1916-to 1959 on file in office of 

Idaho State Reclamation Engineer. No record of October and March diversion except for 

New York Canal. Diversion through New York Canal for period October to March as reported 

by Boise project, Board of Control was: October, 32,900 acre-ft; February, 56,230 acre-ft; 

March 6,910 acre-ft.

2120. Diversions from Boise River between at Boise and Notus gaging stations, Idaho

Between at Boise and at Notus gaging stations, 21 principal canals and several small 

farm laterals divert water from Boise River for irrigation.

Records of total diversions during period April to September for each canal for years 

1919-46 and combined daily diversions covering period April to September for years 

1947-59 in reports of Geological Survey. Records of daily diversions for each canal from 

1916 to 1959 on file in office of Idaho State Reclamation Engineer. Diversions usually 

made also during October and March; no record available.

Records show summation of discharge for these diversions. Staff gages on diversions 

read daily or several times weekly, and discharge measurements made frequently. Field 

data obtained and records summarized under direction of E. B. Karn, water-master for Boise 

River.

162 MALHEUR RIVER BASIN

2200. Malheur River at Little Valley, near Hope, Oreg.

Location. Lat 43°54', long 117°30', in SE£ sec.24, T.19 S., R.42 E., or right bank 

500 ft downstream from bridge at Little Valley, 8 miles southwest of Hope, and 

14 miles southwest of Vale.

Drainage area. 3,010 sq mi, approximately. 

Records available. April 1949 to September 1959.

Gage. Water-stage recorder. Datum of gage is 2,424.03 ft (revised) above mean sea 

level, datum of 1929, supplementary adjustment of 1947.

Average discharge. 10 years, 224 cfs (162,200 acre-ft per year).

Extremes.--Maximum discharge during year, 1,670 cfs Sept. 14 (gage height, 4.80 ft); 

minimum, 17 cfs for many days.

1949-59: Maximum discharge, 12,300 cfs Feb. 24, 1957 (gage height, 11.5 ft, from 

floodmark), from rating curve extended above 1,700 cfs on basis of slope-area measurement of peak flow; minimum, 12 cfs Oct. 27, 1955.

The two greatest floods known occurred in March 1894 and March 1930, on basis of 

records for former station near Namorf.

Remarks.--Records good except those for periods of ice effect, which are poor. Flow

regulated by Warmsprings and Agency Valley Reservoirs (see p. 164). Vale-Oregon Canal 

diverts as much as 600 cfs on left bank at Namorf in sec.31, T.20 S., R.41 E., for 

irrigation of about 31,000 acres, largely below the station. Many small diversions 

for irrigation above station.

Revisions (water years). WSP 1217: 1949-50(M). WSP1397: 1950.

Records available.--May 1933 to September 1934, November 1934, March 1935, March, 

April 1936, June 1937 to September 1959. Monthly discharge only for some periods, 

published in WSP 1317.

;e. Water-stage recorder and concrete control. Altitude of gage is 2,313 ft (by

"evels to reference point furnished by Union Pacific Railroad). Prior to Mar. 15, 1937,

water-stage recorder or staff gage at site 2 miles upstream at different datom.

Mar. 15, 1937, to Jan. 1, 1940, water-stage recorder at present site at datun 0.38 ft

higher.

Average discharge. 23 years (1933-34, 1937-59), 42.3 cfs (30,620 acre-ft per ysar).

Extremes. Maximum discharge during year, 155 cfs Sept. 13 (gage height, 2.00 ft); minimum, 3.3 cfs Apr. 14.

1933-34, 1937-59: Maximum discharge, 8,980 cfs Feb. 24, 1957 (gage height, 10.5 ft, 

from floodraarks), from rating curve extended above 2,600 cfs on basis of sloie-area 

measurement of peak flow; no flow at times.

Remarks. Records good except those for periods of backwater from moss and debris, which 

are fair, and those for periods of iee effect or no gage-height record, whic1? are 

poor. Occasional fluctuations caused by releases from Vale-Oregon Canal which diverts 

water for irrigation of lands west of Vale; considerable return flow at times enters 

Bully Creek above station. Diversions for irrigation of about 7,000 acres above 

station. Records of suspended sediment loads and water temperatures for water year 

1959 are given in WSP 1644.

Location. Lat 44°54'30", long 116 C 07'30", In sec.8, T.18 N., R.3 E., on left bank at 

McCall, a quarter of a mile downstream from outlet of Payette Lake.

Drainage area. 144 sq mi.

Records available.--September 1908 to June 1917, May 1919 to September 1959. Prior to 

October 1942, published as "at Lardo."

Gage. Water-stage recorder. Altitude of gage is 4,970 ft (by barometer). Prio-1 to

Oct. 14, 1908, staff gage at site 1 mile downstream at different datum. Oct. 14, 1908, 

to Dec. 18, 1923, staff gages at sites near present gage at present datum.

Average discharge.--48 years (1908-16, 1919-59), 358 cfs (259,200 acre-ft per year).

Extremes. Maximum discharge during year, 2,490 cfs June 15 (gage height, 6.02 ft); minimum, 8.5 cfs Oct. 5-9 (gage height, 1.39 ft).

PAYETTE RIVER BASIN 173

2410 . Lake Pork Reservoir near McCall , Idaho

Location. Lat 44°54' , long 116°03', in NW^NWi sec. 13, T.18 N. , R.3 E., at outlet gate 

near center of dam on Lake Fork Payette River, 3 miles east of McCall.

Drainage area. 64 sq mi, approximately.

Records available . April 1926 to September 1959 (fragmentary).

Gage. Staff gage and graduations on concrete gate-control structure of dam; gage read 

once or twice daily during irrigation season. Datum of gage is at mean sea level 

(levels by Lake Irrigation District).

Extremes . Maximum contents observed during year, 20,140 acre-ft June 25, 30, July 5, 6 

(elevation, 5,119.00 ft); practically no storage during winter months.

1926-59: Maximum contents observed, 20,140 acre-ft June 24, 25, 1958, June 25, 30, 

July 5, 6, 1959 (elevation, 5,119.00 ft); no storage above elevation 5,101.0 f; for 

long periods during fall and winter of most years.

Remarks . Reservoir is formed by earth- and rock-fill dam completed in 1926. Capacity, 

16,940 acre-ft between elevations, 5,101.0 (lower limit of capacity table, 4.0 ft 

above gate sill of outlet) and 5,117.0 ft (top of f lashboards , 5.0 ft above s~)illway 

crest). Dead storage unknown. Water is used for irrigation of about 6,800 acres of 

land near McCall and Norwood. Figures given herein represent contents above 5,101.0 ft. 

There is some usable storage below elevation 5,101.0 ft, but natural flow passing 

through reservoir when outlet gates are operating prevents withdrawal of storage to 

elevation of sill of gates. Elevation in reservoir during water year 1959 reported 

below 5,101.0 ft as follows: Dec. 2, 5,100.97 ft; Jan. 20, 5,100.50 ft; Feb. 25, dry 

at gage.

Cooperation. Elevation record and capacity table furnished by Lake Irrigation District.

194 SNAKE RIVER MAIN STEM 

2690. Snake River at Weiser, Idaho

Location.--Lat 44°14'40", long 116°58'25", in sec.31, T.ll N., R.5 W., on right bank a 

third of a mile upstream from highway bridge at Weiser and a third of a mile downstream 

from Weiser River.

Drainage area.--69,200 sq mi, approximately.

Records available. October 1910 to September 1959. Fragmentary gage-height record

obtained by U. S. Weather Bureau since 1895. Monthly discharge only for October 1910, 

published in WSP 1317.

Gage. Water-stage recorder. Datum of gage is 2,086.64 ft above mean sea level, datum of 

1929, supplementary adjustment of 1947. Prior to Oct. 1, 1914, staff gage half a mile 

downstream at different datum. Oct. 1, 1914, to Oct. 11, 1933, staff gage at present 

site and datura.

Extremes. Maximum discharge during year, 21,600 cfs Sept. 16 (gage height, 5.68 ft); 

minimum, 9,820 cfs July 3 (gage height, 3.00 ft).

1910-59: Maximum discharge, 84,500 cfs Apr. 29, 1952 (gage height, 14.67 ft); minimum observed, 5,100 cfs Aug. 5, 1924 (gage height, 1.35 ft).

Flood of Mar. 3, 1910, reached a stage of 17.1 ft present site and datum,from reading on old U. S. Weather Bureau gage (discharge, 120,000 cfs). Flood in June 1894 was 

considerably higher.

Remarks. Records excellent except those for doubtful gage-height record, which are good. 

Flow regulated by many reservoirs above station. Diurnal fluctuation caused by Swan 

Falls powerplant. Diversions for irrigation of about 2,473,000 acres (1948 determination) above station.

Revisions (water years) . WSP 1317: 1918. WSP 1567: 1910(M).

DISCHARGE AT PARTIAL-RECORD STATIONS AND MISCELLANEOUS SITES 257

As the number of streams on which streamflow information is likely to be desired far 

exceeds the number of stream-gaging stations feasible to operate at one time, the Geological Survey collects limited streamflow data at sites other than stream-gaging stations. 

When limited streamflow data are collected on a systematic basis over a period of years 

for use in hydrologic analyses, the site at which the data are collected is called a 

partial-record station. Data collected at these partial-record stations are usable in lowflow or flood-flow analyses, depending on the type of data collected. In addition, discharge measurements are made at other sites not included in the partial-record program. 

These measurements are generally made in times of drought or flood to give better areal 

coverage to those events. Those measurements and others collected for some special reason 

are called measurements at miscellaneous sites.

Records collected at partial-record stations are generally presented in two tables. 

However, no records at low-flow partial-record stations are available for the 1959 water 

year. A table of annual maximum discharge at crest-stage stations is given first, followed 

by a table of measurements made at miscellaneous sites for both low flow and high flow.

Crest-stage partial-record stations

The following table contains annual maximum discharges for crest-stage stations. A 

crest-stage gage is a device which will register the peak stage occurring between inspections of the gage. A stage-discharge relation for each gage is developed from discharge 

measurements made by indirect measurements of peak flow or by current meter. The date of 

the maximum discharge is not always certain but is usually determined by comparison with 

nearby continueus-record stations, weather records, or local inquiry. Only the maximum 

discharge for each water year is given. Information on some lower floods may have been 

obtained but is not published herein. The years given in the period of record represent 

water years for which the annual maximum has been determined.

266 INFLOW TO SNAKE RIVER

Inventory of inflow to South bank of Snake River between gaging stations at Milner and 

below Lower Salmon Falls, near Hagerman, Idaho.

Flow at gaging station at Milner is regulated by storage In reservoirs having a combined usable capacity of about 4,700,000 acpe-ft and by diversions above station for irrigation of about 1,340,000 acres of land. At times practically entire flow is diverted. 

Three canals, South Side Minidoka, Milner low lift, and South Side Twin Falls divert from 

left bank of Snake River and contribute to the return flow entering Snake River from 

south bank between at Milner and below Lower Salmon Falls gaging stations. They irrigate 

a combined area reported at 268,170 acres.

Three sets of measurements of all measurable flows entering the river from the south 

bank were made near their mouths during periods Sept. 15-24, 1958, Mar. 24 to Apr. 9, 

1959, and Aug. 3-10, 1959. Some subsurface flow enters below water surface and cannot be 

measured or estimated directly. Results are summarized in table below. Flows measured 

in principal inflow channels are listed separately in the preceding table, "Measurements 

at miscellaneous sites." Measurements in each of the individual return flow channels are 

on file in Boise district office, U. S. Geological Survey, Surface Water Branch.

Between gaging stations Snake River 

at Milner and near Kimberly, Idaho. 

Between gaging stations Snake River 

near Kimberly and near Buhl, Idaho. 

Between gaging stations Snake River
