SURFACE WATER SUPPLY OF SNAKE RIVER BASIN, 1958

SCOPE OF WORK

This volume is one of a series of 18 reports presenting measurements of stage, discharge, and content of streams, lakes, and reservoirs in the United States during the 

water year ending September 30, 1958. Since 1883, when the United States Geological 

Survey first studied streamflow in relation to problems of irrigation, similar measurements have been made at more than 14,000 gaging stations in the 48 States and at many 

others in the Territories of Alaska and Hawaii. On September 30, 1958, the Geological 

Survey and cooperating organizations were maintaining 7,uau gaging stations, including 

those in Alaska and Hawaii. 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 water year October 1, 1957, to September 30, 1953, 

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:

DEFINITION OP 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 wi tli 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 wuere limited stream-flow data are collected systematically over a period of years for use In nydrologic analyses.

Cubic foot per second (cfs) is tie rate of discnarge of a str-am rthose channel is 

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

Cubic feet per second per square mile (cfsni) 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 whicn 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 represontc-u bj a flow of 1 cubic foot per second for
DOWNSTREAM ORDER AND STATION NUMBERS 3

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.

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.

WSP is used as an abbreviation for "Water-Supply Paper" in references to previously 

published reports.

DOWNSTREAM ORDER AND STATION NUMBERS

Beginning with the series of reports for the water year ending September 30, Id51, 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-stern 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 indention show 

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

rank of the tributary on which eacn 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 distinction 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 has eight digits, but the station number as 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.UO, the station number shown 

in this report is 100. The notation in the two places to the left of the hyphen is the 

part number, it is (13) for all stations in this report and is therefore omitted.
SURFACE WATER SUPPLY, 1958, PART 13 

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 

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 arid 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 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.
EXPLANATION OF DATA 5

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 1958 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 

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 otherwise 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 datums 

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 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 indicator, 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 the 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)" 

that only the instantaneous minimum was revised; and "(P)" that only peak discharges were
6 SURFACE WATER SUPPLY, 1958, PART 13

revised. If the drainage area has been revised, the report in which the revised figu.-d 

was first published is given. It should be noted that for all stations for whio\ 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 and runoff in inches 

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

annual series of reports.

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 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 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 crest stage. 

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. 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.
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 7

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.

For moat 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 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 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 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" 

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

5 percent; "good," less that 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.
8 SURFACE WATER SUPPLY, 1958, PART 13

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 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 

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.

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

lines. Formerly, the results of streamflow measurements were published in 14 volumes,

HYDROLOGIC CONDITIONS

Runoff was above median during the water year in most of the area covered by this 

report except during April when runoff was generally below median. Flooding occurred in 

the Weiser River basin, Idaho, in February, where several streams approached maximum 

known stages, and Pine Creek near Cambridge reached a new peak of record. Below average 

temperatures in April delayed melting from the higher elevation snowfields in central 

Idaho. May temperature was far above average and runoff accelerated to produce mean 

monthly flows higher than any other month of record in upper Big Wood River basin and in 

Boise River basin above Arrowrock Reservoir. Peak flows, highest of record or near the 

maximum of record, occurred in some tributaries in the upper Big Lost, Big Wood, and 

South Fork of Boise River drainages during May. Runoff was below median in upper Snake 

River basin during July, August, and September. However, as a result of return flow 

from ample irrigation supplies in southern Idaho, mean monthly flow at Snake River at 

Weiser during August and September reached within 2 percent of the maximum of record for 

these months. For two key gaging stations in the area covered by this report, a comparison of the monthly and annual mean discharge during the 1958 water year with the median 

discharge for the 25-year period (1921-45) is shown in figure 2 on the following page.

SNAKE RIVER MAIN STEM

105. Jackson Lake at Moran, Wyo.

Location. Lat 43°51', long 110°35', in sec. 18, T. 45 N. , R. 114 W. , near left end of 

spillway over dam on Snake River at Moran.

Drainage area. 824 sq mi.

Records available.--July 1908 to September 1958 (1908-10 fragmentary).

Gage. Electric tape gage read once daily. Datum of gage is 2.19 ft above mean sea level, 

unadjusted. Prior to June 1, 1941, staff gage at site 300 ft upstream at same datum.

Extremes.--Maximum contents during year 845,700 acre-ft June 28 (gage height, 6,768.95 ft); 

minimum, 450,780 acre-ft Apr. 16 (gage height, 6,752.57 ft).

1908-58: Maximum contents, 857,220 acre-ft June 23, 1937 (gage height, 6,769.40 ft); 

no usable content several days during period August to October 1919.

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

Cooperation. Reservoir gage heights and capacity table furnished by Bureau of Reclamation.

SNAKE RIVER MAIN STEM

iver near Heist;, Idahc

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.

Records available.--September 1910 to September 1958. 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 

1929. 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. 4b years, 6,360 cfs (4,966,000 acre-ft per year).

Extremes. Maximum discharge during year, 19,100 cfs May 25 (gage height, 6.71 ft); minimum, 540 cfs Dec. 5.

1910-53: 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, -0.13 ft).

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

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

partly regulated by Jackson Lake (see p. 13) and Palisades Reservoir (see p. 27). Station is above all irrigation diversions from main river except Riley ditch (4,800 

acre-ft diverted during year) which diverts 1-j 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 1953 are 

given in W3P 1574.

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

HENRYS FORK BASIN

Location. Lat 44°36', long 111°21' , in SW£ 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 former Lake 

Post Office.

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

Records available. May 1920 to September 1958 (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 

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

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

Average discharge.--29 years (1929-58), 46.7 cfs (33,810 acre-ft per year).

Extremes. Maximum discharge during year, 498 cfs Aug. 18 (gage height, 3.75 ft); minimum, 9 cfs Oct. 6 to Nov. 15.

1920-58: Maximum discharge, 907 cfs June 13, 1926 (gage height, 5.40 ft); no flow 

part of 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. 41). Since 1923, floodwaters of Dry (Tyghee) 

Creek have been diverted at times into Henrys Lake (none diverted during 1958).

Revisions.--WSP 1217: Drainage area.

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, 138,215 acre-ft May 13 (elevation, 6,303.37 ft); 

minimum, 17,170 acre-ft Sept. 23 (elevation, 6,274.46 ft).

1938-58: Maximum contents, 140,515 acre-ft May 13, 1957 (elevation, 6,303.65 ft); 

minimum after first filling of reservoir in May 1939, 16,855 acre-ft Sept. 27, 1940

44 BLACKFOOT RIVER BASIN

£85. Blackfoot River near Blackfoot, Idaho

Location.--Lat 43°07'50", long 112°28'35", at east quarter corner of sec. 23, T. 33., 

R. 34 E., on left bank 135 ft downstream from highway bridge, 2 miles upstream from 

mouth, and 6 miles southwest of Blaokfoot.

Drainage area. 1,295 sq mi, including that of Sand Creek whose flow is diverted to 

Elackfoot River through the Idaho canal.

Records_ available.--July 1913 to September 1958 (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-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.--27 years (1931-58), 155 cfs (112,200 acre-ft per year).

Extremes.--Maximum discharge during year, 1.030 cfs Apr. 30 (gage height, 6.30 ft); minimum, 4 cfs July 17 (gage height, 1.08 ft).

1913-53: Maximum discharge, 1,040 cfs May 26, 1957 (gage height, 7.04 ft); no flow 

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 are poor. Flow regulated by Blackfoot-Marsh Reservoir (capacity at spillway crest, 312,000 acre-ft, 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.

1929 (preliminary adjustment). Prior to July 6, 1913, staff gages at practically same 

site and datum.

Average discharge.--32 years (1926-58), 4,045 cfs (2,928,000 acre-ft per year).

Extremes.--Maximum discharge during year, 13.000 cfs May 13 (gage height, 7.28 ft); minimum, 225 cfs Aug. 9 (gage height, 0.31 ft).

1910-58: Maximum discharge, 46,200 cfs June 18, 1918 (gage height, 14.80 ft); 

minimum, 111 cfs Nov. 10, 1934 (gage height, 0.80 ft).

Late in summer of 1905 there was no flow in Snake River for a distance of 10 miles 

in vicinity of Blackfoot. On Aug. 9, 1905, discharge of Snake River just below mouth 

of Blackfoot River was 39 cfs, supplied by ground-water inflow a short distance 

upstream.

Remarks.--Records excellent. Plow regulated by Jackson Lake (see p. 13), Palisades Reservoir (see p. 27), Henrys and Crassy Lakes (see p. 41), Island Park Reservoir (see 

p. 31), and Blackfoot Marsh Reservoir, having a combined capacity of 2,883,000 acre-ft.

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 flowline of Oakley Reservoir, 5 miles upstream from 

Trapper Creek, 6 miles upstream from Oakley Dam, and 9 miles southwest of Oakley.

Drainage area. 633 sq mi (revised).

Records available . April 1911 to September 1916, March 1919 to September 1958. Monthly 

discharge only for some periods, published in WSP 1317.

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

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

Average discharge.--44 years, 45.7 cfs (33,090 acre-ft per year).

Extremes. Maximum discharge during year, 557 cfs Feb. 17 (gage height, 4.87 ft); minimum, 3.0 cfs Sept. 13 (gage height, 1.27 ft).

1911-16, 1919-58: 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 poor.

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. 64).

published in WSP 1317.

Gage.--Water-stage recorder. Datum of gage is 4,062.9 ft above mean sea level, datum of 

T929. Prior to May 28, 1919, staff gages at slightly different sites and datums.

Average discharge.--32 years (1926-58), 2,083 cfs (1,508,000 acre-ft per year).

Extremes.--Maximum discharge during year, 7,620 cfs Apr. 7 (gage height, 11.80 ft); minimum, 90 cfs Apr. 21 (gage height, 2.76 ft).

1909-58: Maximum discharge, 40,000 cfs June 21, 1918 (gage height, 19.9 ft, site 

and datum then in use); minimum, 2 cfs Mar. 17-28, 1936 (gage height, 1.18 ft).

Remarks. Records good. Flow regulated by American Falls Reservoir (see p. 52), Lake 

Walcott (see p. 58), and other reservoirs having a combined usable capacity of about 

4,700,000 acre-ft. About 1,340,000 acres of land irrigated by diversions from river 

and its tributaries above station, from which the return flow in large part enters 

Snake River between Milner and King Hill stations. Flow includes some stored water 

released for use downstream by Idaho power Co.

Cooperation. Gage-height record furnished by Twin Falls Canal Co. -and North Side Canal 

Co.

1955-58: Maximum discharge, 298 cfs Feb. 15, 1957 (gage height, 2.89 ft), from 

rating curve extended above 150 cfs on basis of conveyance study and logarithmic 

plotting; minimum, 56 cfs Mar. 7, 1956 (gage height, 1.48 ft).

Remarks.--Records good. Only leakage passes Salmon River Canal Co. dam, where flow is 

diverted for irrigation. Flow at station is derived from seepage past dam, underground flow from adjacent irrigated land, and surface waste over rim of canyon. 

Diversion by pumping below Salmon River Canal Co. dam and above station for irrigation 

of 2.,400 acres in project of Magic Water Company, Inc.

Correction. Mean discharge for water year 1956 has been corrected to 106 cfs superseding 

 Igure published in WSP 1447.

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

Extremes. Maximum contents during year, 27.000 acre-ft May 9-11, 14, 15; maximum gage 

height 6.34 ft May 12 (affected by wind); minimum contents, 4,210 acre-ft Aug. 6, 7 

(gage height, 0.42 ft).

1921-58: 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. By-pass was not used during 1958. 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 frequently disturb the recording of lake stages.

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

supplemental staff-gage readings furnished by Owsley Canal Co.

Revisions. WSP 1247: Drainage area.

Gage. Water-stage recorder. Datum of gage is 6,061.80 ft above mean sea level, unadjusted. Prior to Sept. 22, 1934, at site 550 ft upstream at different datums (datum 

raised 1 ft Apr. 20, 1920). Staff gage on Wackay Reservoir is used as an auxiliary 

gage during periods of backwater from reservoir.

Average discharge.--39 years, 73.3 cfs (53,070 acre-ft per year).

Extremes. Waximum discharge during year, 1,000 cfs Way 25 (gage height, 5.52 ft)- no

5.97 ft July 2, 1957 (backwater from Wackay Reservoir); no flow for long periods in 

many years.

Remarks.--Records good except those "below about 10 cfs, which are fair, and those for

periods of no gage-height record, which are poor. Diversions above station for irrigation. See page 101 for total surface inflow to Wackay Reservoir. Zollinger ditch, on 

left bank, sometimes carries water past station but flow was negligible for current 

year.

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.

Records available.--January 1919 to September 1958.

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, 38,400 acre-ft May 25, 29, June 1. 4, 

28-30, July 6 (gage height, 62.00 ft); minimum observed, 7,230 acre-ft Sept. 30 (gage 

height, 27.40 ft).

1919-58: 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

T9T7-18; 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 (bottom 

of outlet tunnel) 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 represent usable contents.

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

RILEY CREEK BASIN 107

1340. Riley Creek below Lewis Spring, near Hagerman, Idaho

Location. Lat 42°45'50", long 114°51 1 30", in SE^NW^ sec. 6, T. 83., R. 14 E., on left 

bank 560 ft downstream from confluence of Riley Creek springs and Lewis Spring, an 

eighth of a mile downstream from U. S. Fish Hatchery, and 4 miles southeast of 

Hagerman.

Records available.--June 1951 to September 1958.

Gage. Water-stage recorder. Altitude of gage is 2,955 ft (from topographic map). Prior 

to June 17, 1955, at site 1,200 ft downstream at different datum.

Average discharge.--? years, 62.8 cfs (45,460 acre-ft per year), excluding diversion from 

Bickel Spring.

Extremes.--1951-58: Maximum daily discharge, 78 cfs Nov. 14, 15, 20-23, 1953; minimum 

 daily, 50 cfs July 7, 21, 22, 29, 30, Oct. 3-5, 1956.

9.42 ft Feb. 27, 1957 (ice jam); no flow July 29, 1931, Oct. 3, 1938.

Remarks. Records excellent except those for period of shifting-control, which are good, 

and those for periods of no gage-height record, which are poor. Diversions for irrigation of about 52,200 acres (1950) above station. Plow 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 for 

Dietrich Canal via Little Wood River at Richfield.

Apr. 1, 1948, staff gage at site 400 ft upstream at datum 1.95 ft higher. Apr. 1, 

1948, to May 22, 1951, staff gages at present site at different datum prior to Apr. 12, 

1949; at present datum thereafter. Supplementary gage 500 ft downstream from siphon 

efflux, used June 1, 1949, to May 22, 1951.

Extremes.--1930-58: Maximum daily discharge, 348 cfs July 2, 1956; no flow or small flow

12K SNflKE RIVER MAIN STEM

1545. Snake River at King Hill, Idaho

Location. Lat 43°00' , long 115°11', in SW£ sec. 7, T. 5 S., R- 11 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 1958.

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

site and datum.

Extremes. Maximum discharge during year, 19,000 cfs Apr. 25 (gage height, 9.71 ft); minimum, 2,150 cfs Jan. 1 (gage height, 2.74 ft); minimum daily, 7,430 cfs July 13, 18.

1909-58: 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 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 1958 are given in WSP 1574.

CANYON CREEK BASIN 

1605. Mountain Home feeder canal near Mountain Home, Idaho

129

Location. Lat 43°13' , long 115°42', in sec. 36, T. 2 S., R. 6 E., on right bank 40 ft 

downstream from point of diversion from Canyon Creek and 5 miles north of Mountain 

Home.

Records available . April 1924 to September 1929, April 1931 to September 1958 (irrigation seasons only 1924-29, 1931-35, 1938-45).

Gage. Water-stage recorder and concrete control. Altitude of gage is 3,330 ft (by barometer). Prior to May 4, 1924, staff gage and May 4, 1924, to Sept. 30, 1929, waterstage recorder, at site 30 ft downstream at datum 0.07 ft lower.

Extremes.--1924-29. 1931-58: Maximum daily discharge, 182 cfs Jan. 1, 1943; no flow at 

times most years.

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

which are poor. Canal diverts from Canyon Creek in sec. 36, T. 2 S., R. 6 E., and 

delivers water to Mountain Home cooperative canal, which heads in Mountain Home feeder 

canal half a mile below station, for irrigation of about 5,000 acres in Mountain Home 

Irrigation District. During nonirrigation season and at time when there is a surplus 

of water for irrigation, canal feeds directly into Mountain Home Reservoir. No diversion from canal above station. Flow regulated by headgates in Canyon Creek and by Long 

Tom and Little Camas Reservoirs.

Discharge, in cubic feet per second, water year October 1957 to September 1958

and 2-f miles northwest of Bennett (Dixie Store).

Drainage area.--982 sq mi.

Records available.--April 1943 to September 1958 (includes flow of Dixie Creek prior to 

October 1946 and excludes Dixie Creek thereafter).

Gage. Water-stage recorder. Altitude of gage is 3,850 ft (from topographic map of Bureau 

of Reclamation).

Average discharge.--15 years, 1,020 cfs (738,400 acre-ft per year).

Extremes.--Maximum discharge during year, 7,510 cfs May 20 (gage height, 9.13 ft); minimum, 

16 cfs Oct. 28 (gage height, 1.42 ft).

1943-58: Maximum discharge, 9,850 cfs May 25, 1956 (gage height, 10.56 ft); minimum, 

0.3 cfs Feb. 16, 1950 (gage height, 0.99 ft), but may have been less during period of 

ice effect.

Remarks. Records excellent. Flow of Little Camas Creek stored in Little Camas Reservoir 

(no spill most years) and diverted through Little Camas Canal (see p. 145) for irrigation of about 5,000 acres of land in vicinity of Mountain Home. Flow regulated by 

Anderson Ranch Reservoir (see preceding page) beginning Dec. 15, 1945.

14 E BOISE RIVER BASIN

13, T. 3 N., R. 4 E., at dam on Boise

Drainage area.--3.210 sq mi, approximately. 

Records available.--October 1917 to September 1956.

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

(surveys of Brueau of Reclamation).

Extremes.--Maximum contents observed during year, 291,600 acre-ft June 26 (elevation, 

2,217.6 ft); no usable contents Oct. 6-14 when sluice gates were open.

1917-5b: Maximum contents observed, 301,200 acre-ft May 29, 1948 (elevation, 

3,219.1 ft); no usable contents during period in each of several y^ars 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 tablts reduced by amounts varying from 347 acre-ft at elevation 2,974 ft 

to 5,000 acre-ft at elevation 3,035 ft and above. Water is used fur irrigation in 

Boise Valley.

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

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 1947-58 

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

1958 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, watermaster for Boise 

River.

southwest of Vale.

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

Records available.--April 1949 to September 1958.

C!ag_e_.--Water-stage recorder. Datum of gage is 2,424.13 ft above mean sea level, datum of 

1929, supplementary adjustment of 1947.

Average discharge.--9 years, 238 cfs (172,300 acre-ft per year).

Extremes. Maximum discharge during year, 4,9GO cfs Feb. 16 (gage height, 7.52 ft), from 

rating eurve extended above 1,700 cfs as explained below; minimum, 19 cfs Jan. 7, 8 

(gage height, 1.61 ft).

1949-58: Maximum discharge, 12,300 cfs Feb. 24, 1957 (gage height, 11.E ft, from 

floodmark), from rating curve extended above 1.7UO cfs on basis of slope-area measurement of peak flow; minimum, 1C 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 or no gage-height record, 

which are poor. Plow regulated by Warmsprings and Agency Valley Reservoirs (see 

P. 167). Vale-Oregon Canal diverts as much as 600 cfs on left bank at Namorf in 

sec. 31, T. 20 3., R. 41 E., for irrigation of about 31,000 acres, largely below the 

station. Many small diversions for irrigation above station.

2545. Lost Creek near Tamarack, Idaho

Location.--Lat 44°57' , long 116°28', in SE£NW£ sec. 28, T. 19 N. , R. 1 W. , on right bank 

a quarter of a mile downstream from dam of Lost Valley Reservoir, 4 miles west of 

Tamarack, and 16 miles north of Council.

Drainage area.--29.4 sq mi.

Records available . January 1910 to August 1914, May 1920 to September 1921, May 1924 to 

November 1929 (fragmentary); March 1930 to September 1958.

Gage. Water-stage recorder. Datum of gage is 4,729.6 ft above mean sea level (riverprofile survey). Prior to Apr. 1, 1912, staff gage at same datum.

Average discharge.--28 years (1930-58), 39.6 cfs (28,670 acre-ft per year).

Extremes.--Maximum discharge during year, 513 cfs May 12 (gage height, 3.52 ft); no flow 

Nov. 22 to Jan. 28.

1910-14, 1920-21, 1924-58: Maximum discharge, 688 cfs May 17, 18, 1921 (gage 

height, 4.29 ft); no flow at times when gates in dam were closed.

Remarks. Records good except those below 10 cfs, which are fair, and those for periods of 

no gage-height record, which are poor. No diversion between reservoir and station; 

practically entire flow diverted below station during irrigation season. Plow regulated since 1910 by Lost Valley Reservoir (see preceding page).

Cooperation. Water-stage recorder inspected occasionally by employees of Lost Valley 

Reservoir Co.

PALOUSE RIVER BASIN 257

3510. Palouse River at Hooper, Wash.

Location. Lat 46°45'30", long 118°08'50", in SEi sec. 27, T. 15 N., R. 37 E., on left 

bank 150 ft downstream from State Highway 11B bridge at Hooper and 0.4 mile upstream 

from Cow Creek.

Drainage area. --2, 540 sq mi, approximately.

Records available.--April to August 1897 (gage heights only), September 1897 to December 

1899, April 1900 to April 1907, June 1908 to July 1912, March 1913 to March 1916, 

February 1951 to September 1958. Prior to 1904, sometimes published as "near Hooper."

Gage. Water-stage recorder. Altitude of gage is 1,040 ft (from topographic map). Apr. 1 

to Aug. 31, 1897, staff gage at site 2? miles upstream at different datum. Sept. 9, 

1897, to March 1916, various staff gages at site ij- miles upstream from present site 

at different datums. Feb. 8 to Mar. 28, 1951, staff gage at present site and datum.

Average discharge.--20 years (1897-99, 1900-1906, 1908-11, 1913-15, 1951-58), 623 cfs 

(451,000 acre-ft per year).

Extremes. Maximum discharge during year, 7,760 cfs Feb. 13 (gage height, 11.55 ft); minimum, 5.6 cfs Aug. 23 (gage height, 3.11 ft).

1897-1916, 1951-58: Maximum discharge, 29,800 cfs Mar. 2, 1910 (gage height, 

22.00 ft, from graph based on gage readings, site and datum then in use); no flow for 

part of June 25, 1910.

Correction.--The 1908 and 1909 momentary maxima were erroneously published in 

WSP 1317. TTIere is no momentary maximum discharge for water year 1908 and 17,700 cfs 

(not previously published, estimated) is the momentary maximum discharge for water 

year 1909.

Remarks. Records good except those for period of ice effect, which are fair, and those 

below 25 cfs, which are poor. No regulation. Diversions above station for irrigation, 

domestic and municipal use.

DISCHARGE AT PARTIAL-RECORD STATIONS AND MISCELLANEOUS SITES 259

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 

f®r use In hydrologlc 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 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 for both low flow and high flow are given in a third table.

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 inspect 

tions 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 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. The maximum discharge for 

each year since the crest-stage gage was established is given. The peak discharge for 

some years may have been published in a previous report as a measurement of discharge. 

Figures given herein supersede all previous figures of peak discharge for the floods 

listed.
