SURFACE WATER SUPPLY OP SNAKE RIVER BASIN, 1960

SCOPE OP 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 1960 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 

15,500 gaging stations in the 50 States. On September 30, 1960, the Geological Survey 

and cooperating organizations were maintaining 7,300 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 

1960 water year at gaging stations, partial-record stations, and miscellaneous gites 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, 

and Idaho Department of Fish and Game, 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 12 were in Idaho, 2 in Oregon, 6 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, Big Wood, Little Wood, 

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

Oregon: Baker, Malheur, Union, and Wallowa Counties; Idaho Power Co.; Pacific 

Power & Light Co.; and Warmsprings Irrigation District.

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 hydrologlc 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 u?ed 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 pe~ second for 

24 hours. It is equivalent to 86,400 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 of 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.
EXPLANATION OF DATA

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 noncontrlbuting 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 

%hich gaging' stations are on tributaries between any two stations on a main stem 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 f'.rst all 

stations on the main stem from headwaters toward mouth, then all stations on th3 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 distinction is made 

between partial-record stations and regiilar 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-tfischarge 

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

determining the daily flow. The records of stage are obtained either from direct readings on a nonrecordlng gage or from a water-stage recorder that gives a continuous record
4 SURFACE WATER SUPPLY, I960, 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 detris 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 Jhe 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 and 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 1960 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 b;r the 

Corps of Engineers unless otherwise noted. Under "Records available" are given the 

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

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

daturns of previous gages used during the period of records available. The reference to 

"datum of 1929" and adjustments of other years are to the datum and adjustments of the 

U. S. Coast and Geodetic Survey. 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 minimum gage height (unless it Is of no importance). In the 

first paragraph, the data given 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 otherwise qualified, the maximum discharge corresponds to the crest 

stage obtained by use of a water-stage recorder, a crest-stage gage, or a non-recording 

gage read at the time 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 been 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 that only the instantaneous maximum discharge was revised; 

"(m)'1 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 ard 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, 1960, PART 13

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

discharge for the greater part of the open-water period was determined by the ahiftingcontrol method, the slope method, or other special methods involving an eq-iivalent 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-heigf t 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 cuMc feet per 

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

large noncontributing 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 crept atage. 

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

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

most stations are listed below the table of daily and monthly discharge. A31 independent 

peaks above the selected base are given. The base discharge, which is giver 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 footrote 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 OP FIELD 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 atage 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 hot 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 gating stations on a regular basis and published in the quallty-of-water reports. At manv 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 temperature 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 gi\en 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 measrrements at 

miscellaneous sites.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of streamflow data depends primarily on (1) the stability of the 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" 

indicate? 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 aid 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 such stations, 

figures of cubic feet per second per square mile and of runoff in inches are rot 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
8 SURFACE WATER SUPPLY, I960, 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 nade 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 2u volumes, including one each for the States of Alaska and Hawaii. The 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 supply 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 

Parts 1, 2, 3, and 6. The boundaries of the various parts are indicated by the following

Note. Records for all stations in Oregon through September 1910 are contained In WSP 370, supersedlng 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 reexamined and 

revised where warranted. 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 information 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 

special reports also contain other pertinent hydrologic information and analyses and 

compilations of data relating to earlier notable floods. The list on the following page

.HYDROLOGIC CONDITIONS

Streamflow was excessive in Clearwater River at the lower end of Snake River basin. In 

contrast, streamflow was deficient in Snake River above Palisades Reservoir and in Goose 

Creek and Portneuf River basins. Mean annual discharge was lower than for any year since 

the serious drought of 1934 in Big Wood River basin above Magic Reservoir and Snake River 

basin above Jackson Lake, lower than any year since 1937 in Big Lost River basin, and 

lower than any year since 1940 in Mud Lake basin. Flow of Snake River at King Hill, which 

measures the return flow from 1.6 million acres of irrigated land and spring flow from the 

Snake River plain, was less than for any year since 1941. Most streams above Weiser, Idaho, 

flowed considerably below average. Maximum monthly flows of record for October occurred 

in the Clearwater, Salmon, and Boise River basins. Flash floods from thunderstorms 

occurred in Jenkins Canyon, a tributary of Portneuf River, and in One Mile Creek, a tributary of Raft River, on August 1. Peak discharge for Jenkins Canyon was 2,360 cfs from . 

about 5 square miles.

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

by Bureau of Reclamation). Prior to June 1, 1941, staff gage at site 300 ft upstream 

at same datum.

Extremes. Maximum contents during year, 850,300 acre-ft June 19 (elevation, 6,769.13 ft) 

minimum, 374,960 acre-ft Sept. 30 (elevation, 6,749.19 ft).

1908-60: Maximum contents, 857,220 acre-ft June 23, 1937 (elevation, 6,769.40 ft); 

no usable contents for several days during period August to October 1919.

Remarks. Reservoir was formed by log crib dam in 1906 with a usable capacity o^

300,000 acre-ft. This dam washed out in July 1910 and was replaced by an earth dam, 

forming a reservoir with a usable capacity of 380,000 acre-ft. The earth dan was 

raised in 1916, increasing the usable capacity to 790,000 acre-ft. In 1917, by 

dredging the outlet, the capacity was further increased to 847,000 acre-ft b?tween 

elevations 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.

SNAKE RIVER MAIN STEM 

375. Snake River near Heise, Idaho

27

Location. Lat 43°36'45", long 111°39'05", in SW£ sec.5, T.3 N., R.41 E. , on left bank 

500 ft upstream from Anderson canal headgate, 3 miles upstream from Heise, 6 miles east 

of Ririe, and 23 miles upstream from Henrys Fork.

Drainage area. 5,752 sq mi. Mean altitude, 7,770 ft.

Records available. September 1910 to September 1960. Monthly discharge only for some 

periods, published in.WSP 1317. Prior to 1911, published as South Fork of Snake River 

near Heise.

Gage. Water-stage recorder. Datum of gage is 5,015.3 ft above mean sea level, datum of 

T929. Prior to July 9, 1913, staff gage and July 9, 1913, to Sept. 29, 1922, waterstage recorder, at datum 2.65 ft higher. Sept. 30, 1922, to Oct. 5, 1933, water-stage 

recorder at datum 2.0 ft higher.

Average discharge. 50 years, 6,830 cfs (4,945,000 acre-ft per year).

Extremes. Maximum discharge during year, 15,100 cfs July 29 (gage height, 5.66 ft); minimum, 1,180 cfs Feb. 18 (gage height, 1.06 ft).

1910-60: Maximum discharge, about 60,000 cfs May 19, 1927, result of washing out 

of landslide on Gros Ventre River (gage height, about 16.0 ft, present datum); minimum, 

460 cfs Nov. 10, 12, 1956 (gage height, -0.18 ft).

Flood in early June 1894 was probably as great as flood of May 19, 1927.

Remarks. Records excellent except those for period of ice effect, which are good. Flow 

partly regulated by Jackson Lake (see p. 13) and Palisades Reservoir (see p. 25). 

Station is above all irrigation diversions from main river except Riley ditch (5,920 

acre-ft diverted during year) which diverts l£ miles upstream from station. About 

107,000 acres in Wyoming and Idaho irrigated by diversions from tributaries above 

station. Records of chemical analyses and water temperatures for the water year 1960 

are given in WSP 1744.

Revisions (water years).--WSP 1217: Drainage area. WSP 1347: 1912.

28 HENRYS PORK BASIN

395. Henrys Fork near Lake, Idaho

Location. Lat 44°36', long 111°21', in SWi sec.26, T.15 N., R.43 E., on left bank a 

quarter of a mile downstream from Henrys Lake Dam and 4 miles south of fcrmer Lake 

Post Office.

Drainage area.--98 sq mi, approximately, including 6 sq mi of Dry Creek basin.

Records available.--May 1920 to September 1960 (prior to October 1929, irrigation seasons 

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

Gage. Water-stage recorder. Datum of gage is 6,450.62 ft above mean sea level, levels 

oy Bureau of Reclamation (Corps of Engineers bench mark). Prior to September 1922, 

staff gage at site 3 miles downstream and below mouth of Dry Creek at different datum.

Average discharge. 31 years (1929-60), 47.2 cfs (34,170 acre-ft per year).

Extremes.--Maximum discharge during year, 299 cfs Sept. 8 (gage height, 2.97 ft); minimum 

not determined, occurred sometime during period of no gage-height record.

1920-60: Maximum discharge, 907 cfs June 13, 1926 (gage height, 5.40 ft); no flow 

for part of each day Sept. 17, 18, 1952.

Outflow from Henrys Lake was reported to have ceased entirely late in summer of 1889.

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

Flow regulated by Henrys Lake (see p. 39). Since 1923, floodwaters of Dry (Tyghee) 

Creek have been diverted at times into Henrys Lake (some diverted during I960).

Location. Lat 44 025'11", long 111°23 I 52", a quarter of a mile south of quarte" corner 

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

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 1960.

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

b~y Bureau of Reclamation).

Extremes. Maximum contents during year, 136,990 acre-ft Apr. 13 (elevation, 6,303.22 ft); 

minimum, 12,760 acre-ft Sept. 30 (elevation, 6,270.66 ft).

1938-60: Maximum contents, 140,515 acre-ft May 13, 1957 (elevation, 6,313.65 ft); 

minimum after first filling of reservoir in May 1939, that of Sept. 30, 1960.

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.

42 BLACKFOOT RIVER BASIN

685. Blackfoot Rive^ near Bla^kfoot, Idaho

Location. Lat 43°07'50", long 113°28'35", at east auarter corner of sec.28, T.3 S., 

R.34 E., on left bank 125 ft downstream from nisrhway bridge, 2 miles mstream from 

mouth, and 8 miles southwest of B.1 ckfo-.t.

Drainage area. 1,295 sq mi, including fra i S. S?~ii Creek whose flow is diverted to Blackfoot River through the Idaho canal.

Records available. July 1913 to September 1960 (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 (river-profile 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.--29 years (1931-60), 152 cfs (110,000 acre-ft per year).

Extremes.--Maximum discharge during year, 1,070 cfs Mar. 9 (gage height, 6.42 ft); no flow 

May 10-13, 16-18, June 1-3. 

1913-60: Maximum discharge, that of Mar. 9, 1960; no flow for many dfys.

Remarks. Records good except those below 5 cfs and those for periods of ice effect or no 

gage-height record, which are poor. Flow regulated by Blackfoot-Marsh Reservoir (capacity at spillway crest, 312,000 acre-ft, and maximum capacity with flaslr boards , 413,000 

acre-ft). Many diversions above station for irrigation. Most of fl^w during nonirrigation season and part of that during irrigation season is supplied by waste from Snake 

River canals.

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

Revisions. WSP 1217: Drainage area. 

Rating table, water year 1959-60, except periods of ice effect (gage height, In feet, and

discharge, in cubic feet per second)

Drainage area. 182 sq mi. Mean altitude, 5,670 ft.

Records available. May 1955 to September 1960 (discontinued).

Gage. Water-stage recorder. Altitude of gage is 4,720 ft (from topographic map).

Average discharge. 5 years, 5.14 cfs (3,720 acre-ft per year).

Extremes. --Maximum discharge during year, 275 cfs Mar. 6 (gage height, 6.21 ft); no flow 

for long periods.

1955-60: Maximum discharge, that of Mar. 6, 1960, from rating curve extended above 

70 cfs on basis of slope-area measurement at gage height 6.10 ft; no flow for long 

periods in each year.

Remarks. Records good except those for periods of ice effect or no gage-height record, 

which are poor. Practically entire flow diverted for irrigation above station during 

growing season. Discharge measurements of East Fork made about once a montl- to 

supplement this record (see p. 254).

60 GOOSE CREEK BASIN

825. Goose Creek above Trapper Creek, near Oakley, Idaho

Location. Lat 42°07'10", long 113°56'20", in sec.13, T.15 S., R.21 E., on right bank 

a quarter of a mile upstream from maximum flowline of Oakely Reservoir, 5 miles 

upstream from Trapper Creek, 5 miles south of Oakley Dam, and 9 miles southwest of 

Oakley.

Drainage area.--633 sq mi. Mean altitude, 6,030 ft.

Records available. April 1911 to September 1916, March 1919 to September 1960. Monthly 

discharge only for some periods, published in WSP 1317.

Gage. Water-stage recorder. Altitude of gage is 4,770 ft (by barometer). Prior to 

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

Average discharge. 46 years, 44.8 cfs (32,430 acre-ft per year).

Extremes. Maximum discharge during year, 183 cfs Mar. 7 (gage height, 3.23 ft); minimum, 2.2 cfs Nov. 18 (gage height, 1.22 ft).

1911-16, 1919-60: Maximum discharge, 1,670 cfs Jan. 23 or Feb. 2^>, 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 good except those for periods of ice effect or no gage-height record, 

which are fair. 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. 62).

MUD LAKE-LOST RIVER BASINS 85

1150. Mud Lake near Terreton, Idaho

Location. Lat 43°54', long 112°21', In NE^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 1960.

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

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

Extremes. Maximum contents during year, 26,900 acre-ft May 11; maximum gage height,

6.36 ft May 12 (affected by wind); minimum contents, 3,570 acre-ft Nov. 4; minimum gage 

height -0.01 ft Nov. 4 (affected by wind).

1921-60: 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 Camas 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 from 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 1960. Other irrigation 

diversions are made by various means from adjacent, lakes and wells and Camas Creek 

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

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

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

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

for the lake.

Cooperation.--Water-stage recorder inspected by employees of Water District No. 66.

MUD LAKE-LOST RIVER BASINS 93

1260. Mackay Reservoir near Mackay, Idaho

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

on Big Lost River, 4 miles northwest of Mackay.

Drainage area. 788 sq mi.

Records available. January 1919 to September 1960.

Gage. Water-stage recorder. Datum of gage Is 6,000 ft above mean sea level, Utah Conr 

struction Co. datum, or 6,000.4 ft above mean sea level, datum of 1929, Pacific Northwest supplementary adjustment of 1947. Prior to Oct. 15, 1959, staff gage at same site 

and datum.

Extremes. Maximum contents during year, 32,070 acre-ft Apr. 29 (gage height, 56.79 ft); 

minimum not determined.

1919-60: 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, 19?9, 1931-35; 

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

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

1517-18; 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. Prior to Oct. 1, 1959, contents below 1,000 acre-ft may be in error at times 

as readings at gage were too low because of fall in outlet channel. Figures given 

herein represent usable contents.

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

Remarks. Records excellent except those above 200 cfs, which are good, and those for

periods of ice effect or doubtful or no gage-height record, which are fair. Diversions 

above station for irrigation of about 6,450 acres (1950 determination). Storage in 

Little Wood Reservoir (capacity, 12,180 acre-ft) began Feb. 12, 1941. Flow is also 

affected by Campbell, Cameron, and Howard Reservoirs (combined capacity, 690 acre-ft) 

on South Fork Muldoon and Little Fish Creeks.

Cooperation. Water-stage recorder inspected by employees of Little Wood Feservoir Co. and 

Water District No. 11 C.

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

Average discharge. 8 years (1912-13, 1920-21, 1954-60), 149 cfs (107,900 acre-ft per 

year).

Extremes.--Maximum discharge during year, 220 cfs Apr. 5 (gage height, 3.27 ft); maximum 

gage height, 6.56 ft Jan. 7 (ice Jam); minimum discharge, 41 cfs Aug. 14 (gage height, 

2.12 ft).

1911-60: 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 F<?b. 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 above station (1950 determination). Plow partly 

regulated by Little Wood Reservoir (capacity, 12,180 acre-ft), Pish 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.

SNAKE RIVER MAIN STEM 115

 1545. Snake River at King Hill, Idaho

Location. Lat 43°00'10", long 115°12'05", 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 Big Wood 

River.

Drainage area. 35,800 sq mi, approximately. 

Records available. May 1909 to September 1960.

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

Tevels. 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 datum. Aug. 17, 1910, to Oct. 7, 1928, staff gage at present 

site and datum.

Extremes.--Maximum discharge during year, 15,300 cfs Mar. 7 (gage height, 8.65 ft); minimum, 2,980 cfs May 2 (gage height, 3.49 ft); minimum daily, 6,070 cfs May 5.

1909-60; 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,

Remarks.--Records excellent. Flow regulated by powerplants at Lower Salmon Palls 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. Diversions for irrigation of about 

1,590,000 acres above station. Records of chemical analyses and water temperatures for 

the water year 1960 are given in WSP 1744.

Owyhee Reservoir at Owyhee Dam, near Nyssa.

Sage.--Staff gage read once daily. Datum of gage is at mean sea level (levels by Bureau 

of Reclamation).

Extremes. Maximum contents observed during year, 943,800 acre-ft Apr. 18-21 (elevation,

 2,655.10 ft); minimum observed, 577,000 acre-ft Oct. 1 (elevation, 2,615.55 ft).

1932-60: Maximum contents observed, 1,140,000 acre-ft Apr. 15, 1952 (elevation, 

2,671.40 ft); minimum observed since full capacity was attained 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 2,6?0.0 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 wes 4-, 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.

136 BOISE RIVER BASIN

1940. Arrowrock Reservoir at ftrrcwrock, Idaho

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

at Arrowrock, 14 miles east of Boise.

Drainage area. 2,210 sq mi, approximately. 

Records available. October 1917 to September 1960.

Gage. Staff gage graduated on face of dam read once daily. Datum of gage is at mean sea 

level (surveys by Bureau of Reclamation).

Extremes. Maximum contents observed during year, 291,900 acre-ft Apr. 13 (elevation, 

3,217.7 ft); minimum observed, 2,080 acre-ft Sept. 12 (elevation, 3,009.0 ft).

1917-60: 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 

ralFed 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.

BOISE RIVER BASIN 143

2045. Diversions from Boise River between near Boise and at Boise gaging stations, Idaho

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 for years 1947-60, 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 1916-60 on file In office of Idiho State 

Reclamation Engineer. No record of October to March diversions 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, 3,400 acre-ft; January, 854 acre-ft; February, 62,060 

acre-ft; March, 72,160 acre-ft.

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

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

obtained and records summarized under direction of E. B. Karn, watermaster for Boise River.

Discharge, in cubic feet per second, April to September 1960

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

Between at Boise and at Notus gaging stations, 21 principal canals ani 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 1947-60 

in reports of Geological Survey. Records of daily diversions for each canal from 1916-60 

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 gagers 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, watermaster for Boise

Location.--Lat 43°54', long 117°30' , in SE£ sec.24, T.19 S., R.42 E., on right bank 500 ft 

downstream from bridge at Little Valley, 8 miles southwest of Hope, ani 14 miles southwest of Vale.

Drainage area.--3,010 sq mi, approximately. 

Records available.--April 1949 to September 1960.

Gage.--Water-stage recorder. Datum of gage is 2,424.03 ft above mean sea level, datum of 

1929, supplementary adjustment of 1947.

Average discharge. 11 years, 219 cfs (158,500 acre-ft per year).

Extremes.--Maximum discharge during year, 3,910 cfs Mar. 8 (gage height, 6.55 ft); minimum, 21 cfs Feb. 29.

1949-60: 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 slo^e-area measurement of peak flow; minimum, 12 cfs Oct. 27, 1955.

The two greatest floods known occurred in March 1894 and March 1910, 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. 154). 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 station. Many small diversions for 

irrigation above station.

Revisions (water years). WSP 1217: 1949-50(M). WSP 1397: 1950.

MALHEUR RIVER BASIN 153

2270. Bully Creek near Vale, Oreg.

Location. Lat 43°57'30", long 117°20 I 30", in SW£ sec.33, T.18 S., R.44 E., on right bank 

5 miles southwest of Vale and 7 miles upstream from mouth.

Drainage area. "570 sq mi, approximately.

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

1936, June 1937 to September 1960. Monthly discharge only for some periods, published 

in WSP 1317.

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

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 datum. 

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

higher.

Average discharge. 24 years (1933-34, 1937-60), 42.0 cfs (30,410 acre-ft per year).

Extremes. Maximum discharge during year, 1,320 cfs Mar. 21 or 22 (gage height, 4.64 ft, 

from floodmark); minimum, 2.8 cfs sometime during period Nov. 5 to Dec. 7, b'it may 

have been less during periods of ice effect.

1933-34, 1937-60: Maximum discharge, 8,980 cfs Feb. 24, 1957 (gage height, 10.5 ft, 

from floodmarks), from rating curve extended above 2,600 cfs on basis of slo^e-area 

measurement of peak flow; no flow at times.

Remarks. Records fair except those for periods of ice effect or no gage-height record 

and those above 50 cfs, which 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 1960 are given in WSP 1744.

PAYETTE RIVER BASIN 163

2410. Lake Fork Reservoir near McCall, Idaho

Location. Lat 44 0 54' , long 116°03' , in NW£NW£ 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 1960 (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 25-28 (elevation,

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

1926-60: Maximum contents observed, 20,140 acre-ft June 24, 25, 1958, June 25, 30, 

July 5, 6, 1959, June 25-28, 1960 (elevation, 5,119.00 ft); no storage above elevation 

5,101.0 ft for long periods in fall and winter of most years.

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

 IFTS'40 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 flashboards, 5.0 ft above spillway 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 feet, in reservoir, during water year 1960 reported 

below 5,101.1 ft as follows:

Jan. 25............. 5,100.40 Feb. 23............ 5,099.90

WEISER RIVER BASIN 173

2515. Weiser River at Tamarack, Idaho

Location.~Lat 44°57', long 116 e 23', in NWlNE^ sec. 31, T.19 N., R.I E., on left bank 

43 ft upstream from railroad bridge, 0.65 mile south of Tamarack, and l£ miles 

upstream from Beaver Creek.

Drainage area. 36.5 sq mi. Mean altitude, 4,69& ft. 

Records available. September 1936 to September1'1960.

Gage. Water-stage recorder. Altitude of gage is 4,080 ft (by barometer). Prior to 

Oct. 8, 1949, staff gage at site a quarter of a mile upstream at different datum.

Average discharge. 24 years, 43.7 cfs (31,640 acre-ft per year).

Extremes. Maximum discharge during year. 511 cfs Apr. 7 (gage height, 4.77 f".}..; minimum, 

1.3 cfs Sept. 9 (gage height, 1.05 ft).

1936-60: Maximum discharge, 1,320 cfs Dec. 22, 1955 (gage height, 7.17 ft), from 

rating curve extended above 600 cfs on basis of slope-area measurement of peak flow; 

minimum, 0.5 cfs Sept. 21, 1958.

Remarks. Records good except those for periods of ice effect, which are fair. No diversion above station. Diurnal fluctuation caused by millpond at Tamarack. Small flow 

from Boulder Creek in Salmon River basin enters Weiser River above station through 

transmountaln diversion during late irrigation season.

SNAKE RIVER-MAIN STEM 243

3435. Snake River near Clarkston, Wash.

Location. Lat 46°25'30", long 117°10'30", in lot 1, sec.16, T.ll N., R.45 E., on right 

bank 2 miles upstream from Alpowa Creek, 7 miles downstream from Clarkston, and 

134 miles upstream from.mouth.

Drainage area. 103,200 sq mi, approximately.

Records available. October 1915 to September 1960 in reports of Geological Survey.

Monthly discharge only for some periods, published in WSP 1317. October 1909 to September 1953 (monthly discharge only) in State Water-Supply Bulletin 6. Prior to October 1935, published as "at Riparia." Gage-height records collected at Riparia 1900-16 

(fragmentary), 1935-48, are contained in reports of U. S. Weather Bureau.

Extremes. Maximum discharge during year, 163,500 cfs June 4 (gage height, 27.80 ft); minimum, 11,900 cfs Aug. 23 (gage height, 8.55 ft); minimum daily, 15,900 cfs Aug. 22.

1909-60: Maximum discharge, 369,000 cfs May 29, 1948 (gage height, 40.36 ft, from 

high-water mark in well); minimum, 6,660 cfs Sept. 2, 1958 (gage height, 6.79 ft).

Maximum stage known, 24.7 ft June 5, 1894, Riparia site and datum, determined from 

floodmarks by U. S. Weather Bureau (discharge, 409,000 cfs).

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

fair. Over 2,840,000 acres are irrigated above station from numerous large irrigation 

projects. Regulation from many storage reservoirs above station and fluctuations during low-water periods from powerplants on Clearwater River at Lewiston, Idaho, and 

Snake River at Brownlee Dam.

DISCHARGE AT PARTIAL-RECORD STATIONS AND 'MISCELLANEOUS SITES 253

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 

low-flow 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 1960 water 

year. A table of annual maximum discharge at crest-stage stations is given f.rst, 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 continuous-record stations, weather records, or local inquiry. Only fie 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.
