SURFACE WATER SUPPLY OF SNAKE RIVER BASIN, 1955

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, 1955. Since 1888, when the United States Geological 

Survey first studied streamflow in relation to problems of irrigation, similar measurements have been made at more than 13,250 gaging stations in the 48 States and at many 

others in the Territories of Alaska and Hawaii. On September 30, 1955, the Geological 

Survey and cooperating organizations were maintaining 6,860 gaging stations, including 

those in Alaska and Hawaii. Discharge measurements only were made at many other points 

in the 1955 water year, most of which are published at the end of this report. The name 

of each stream measured at points other than gaging stations is not listed in the index 

to this report. Only the major river basins in which measurements were made are listed 

under the item "Discharge measurements" in the index.

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, M. R. Kulp, State reclamation engineer; 

Idaho State Pish and Game Commission, Ross Leonard, director; Idaho Water District 

7AB, M. H. Coffin, water-master; and Crane Creek Administration Board, E. W. Horner, 

secretary.

Oregon: Office of the State Engineer, C. E. Stricklin, succeeded by L. A. Stanley, 

and State Highway Commission, B. R. Chandler, chairman. 

Utah: Office of the State Engineer, J. M. Tracy.

Washington: State Department of Conservation and Development, W. A. Galbraith, 

director, through Division of Water Resources, M. G. Walker, supervisor.

Wyoming: Office of the State Engineer, L. C. Bishop.

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, 3 in Oregon, and 4 in Wyoming.

Assistance was also furnished by the Forest Service and the Soil Conservation Service 

of the Department of Agriculture; by the Bonneville Power Administration, Office of 

Indian Affairs, 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:

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 usually be obtained from the district office.

DEFINITION OP TERMS AND ABBREVIATIONS

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

as follows:

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 is the depth to which an area would be covered if all the water draining from it in a given period were uniformly distributed on its surface. The term is 

used for comparing runoff with rainfall, which is also usually expressed in Inches.

Acre-foot is the quantity of water required to cover an acre to the depth of 1 foot 

and is equivalent to 43,560 cubic feet. The term is commonly used in relation to storage 

for irrigation.

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

24 hours. It is equivalent to 86,400 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.
EXPLANATION OF DATA 3

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 OF LISTING GAGING STATIONS

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 #ank 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 each gaging station is situated.

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

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

from source to mouth of the uppermost tributary to the tributary.

EXPLANATION OP 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 date 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. Typical structures in use at gaging 

stations are shown in figure 1.

Rating tables giving the discharge for any stage are prepared from stage-discharge relation curves defined by discharge measurements. If extensions to the rating curve are 

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

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

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

EXPLANATION OP DATA 5

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

tables gives the dally 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 dally 

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

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

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

a station is temporarily changed by the presence of aquatic growth or debris on the 

control, the dally 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 datermlning 

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 stagedischarge 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.

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 

and runoff 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 1955 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 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
6 SURFACE WATER SUPPLY, 1955, PART 13

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 nonrecording 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 revision, 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 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 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
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 7

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. Runoff 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 discharges 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.

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 most gaging stations on lakes and reservoirs the data presented comprise a description of the station and a monthly summary table of stage and contents. For some reservoirs 

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

stages is usually given in the first report in which data for the reservoir are published, 

but it is omitted from succeeding reports.

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 than 10 percent; "fair," less than 15 percent; and "poor,"
8 SURFACE WATER SUPPLY, 1955, PART 13

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.

Runoff 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 runoff in inches are not published 

unless storage or diversion records are included to indicate the extent of the regulation 

or diversion, or unless satisfactory adjustments can be made 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 mus-t first be supplied to existing irrigation systems.

PUBLICATIONS

To facilitate publication of the annual series of reports, the area of the United 

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, one

Note. Records for all stations in Oregon through September 19lO are contained In WSP 370, superseding all earlier reports for these stations.

The records at most of the stations discussed in these reports extend over many years. 

Discharge measurements at many points other than regular gaging stations have been 

made each year and are published at the end of each report. The streams and points of 

measurement are listed in the same order as the streams and gaging stations in the body 

of the report. An Index of the. records obtained before 1904 has been published in WaterSupply Paper 119.

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

HYDROLOGIC CONDITIONS

During most of water year 1955 streamflow In the Snake River basin did not vary greatly 

from the median. Drought conditions continued in the extreme south portion of the basin; 

runoff of Owyhee River near Gold Creek, Nev., was the lowest of record and only 26$ of the 

annual median. In March the runoff in the western half of the basin was deficient, being 

record-low in Clearwater, Salmon, Payette, and Boise River basins. By April the area of 

deficient runoff had spread to cover the entire basin; the flow of Snake River at Heise, 

Idaho, and that of several tributaries, was record-low for April. During July and August 

flow was generally above median in the western part of the basin as a result of snowmelt 

and rain; runoff of several tributaries was near record high-for the respective months. 

For two key gaging stations in the area covered by this report, a comparison of the monthly 

and annual mean discharge during the 1955 water year with the median discharge for the 

25-year period 1921-45 is shown in figure 3 below.

GAGING-STATION RECORDS

SNAKE RIVER MAIN STEM 

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 1955 (1908-10 fragmentary).

Gage. Electric tape gage read once dally. 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 851,330 acre-ft June 27 (elevation, 6,769.17 ft); 

minimum, 190,450 acre-ft Sept. 26 (elevation, 6,740.40 ft).

1908-55: Maximum contents, 857,220 acre-ft June 23, 1937 (elevation, 6,769.40 ft); 

no usable-contents on 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 elevations 

6,730 ft (top of baffles to sluices) and 6,769 ft (top of spillway gates). Water is 

used for irrigation In Snake River Valley, Idaho. Contents as given herein are for 

8 a.m.; all available for release.

Cooperation.--Reservoir elevation and capacity table furnished by Bureau of Reclamation.

1929. Prior to July 9, 1913, staff gage and July 9, 1913, to Sept. 29, 1922, waterstage recorder, at present site at datum 2.65 ft higher. Sept. 30, 1922, to Oct. 5, 

1933, water-stage recorder at present site at datum 2.0 ft higher than present datum.

Average discharge. 45 years, 6,841 cfs (4,953,000 acre-ft per year).

Extremes. Maximum discharge during year, 18,800 cfs June 17 (gage height, 6.73 ft); minimum daily, 1,800 cfs Jan. 7.

1910-55: 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, 

1,210 cfs Jan. 22, 1935 (gage height, 1.15 ft).

Flood during 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). Station is above all irrigation diversions from main river except Riley ditch (5,280 acre-ft diverted during year), which 

diverts li 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 1955 are given in WSP 1403.

Bureau of Reclamation (Corps of Engineers benchmark). Prior to September 1922, staff 

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

Average discharge. 35 years, 49.3 cfs (35,690 acre-ft per year).

Extremes.--Maximum discharge during year, 461 cfs Aug. 4 (gage height, 3.72 ft); minimum 

daily, 8 cfs Oct. 28 to Dee. 25.

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

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

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

Drainage area.--481 sq mi.

Records available. November 1938 to September 1955.

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, 138,540 acre-ft May 12 (elevation, 6,303.41 ft), 

minimum, 26,715 acre-ft Sept. 25 (elevation, 6,280.45 ft).

1938-55: Maximum contents, that of May 12, 1955; minimum after first filling of 

reservoir in Way 1939, 16,855 acre-ft Sept. 27, 1940 (elevation, 6,274.22 ft).

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

Capacity, 127,265 acre-ft between elevations 6,239 ft (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 prevents withdrawal of storage to elevation 

6,230 ft (sill of lower outlet). Dead storage negligible. Water is used for irrigation of lands in Premont-Madison irrigation district between Ashton and Rexburg. Contents given herein are for 8 a.m.; all available for release.

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

Location. Lat 42°31', long 114°01', in sec. 29, T. 10 S., R. 21 E., on left bank 50 ft 

upstream from highway bridge and 700 ft downstream from headgates at Milner Dam.

Records available.--May 1909 to September 1955. Monthly discharge only for some periods, 

published in WSP 1317.

Gage.--Water-stage recorder. Datura of gage is 4,121.5 ft above mean sea level, datum of 

1929. Prior to May 13, 1913, staff gage, and May 13, 1913, to Apr. 24, 1914, waterstage recorder, at highway bridge 50 ft downstream at present datura.

Average discharge . 29 years (1926-55), 1,757 cfs (1,272,000 acre-ft per year).

Extremes. --Maximum discharge during year, 3,810 cfs July 27 (gage height', 10.64 ft); mini-

 mum, 46 cfs Oct. 29 (gage height, 1.35 ft).

1909-55: Maximum daily discharge, 4,600 cfs Aug. 12, 1918, including about 1,200 

cfs wasted through spillway below station and returned to river; maximum discharge for 

irrigation use 3,810 cfs July 21, 1952, July 24, 1953, and July 27, 1955; no flow 

Sept. 20, 1920.

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

controlled by headgates. Diversions began in March 1905 when 30,000 acres were reported as irrigated. By 1912 this had increased to 147,000 acres and during recent years 

the irrigated area has been reported as 202,000 acres.

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

Revisions (water years).--WSP 1347: 1910-16.

1929. Prior to May 28, 1919, staff gages at slightly different sites and daturas.

Average discharge. 29 years (1926-55), 2,039 cfs (1,476,000 acre-ft per year).

Extremes. Maximum discharge during year, 6,550 cfs Apr. 17 (gage height, 10.97 ft); minimum, 5 cfs Sept. 29, 30 (gage height, 1.34 ft).

1909-55: 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. Plow regulated by American Falls Reservoir (see p. 51), Lake 

Walcott (see p. 55) and other reservoirs having a combined usable capacity of about 

3,300,000 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. Plow includes some stored water 

released for use downstream by Idaho Power Co.

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

82 MUD LAKE-LOST RIVER BASINS

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 54 miles northeast of Terreton. Prior to Oct. 1, 1954, at site 2.7 miles southwest.

Drainage area. 1.050 sq mi, approximately, not including Medicine Lodge Creek. 

Records available.--April 1921 to September 1955.

Gage_._"Water-stage recorder. Datum of each 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, 30,600 acre-ft May 7, 8; maximum gage height,

7.02 ft Apr. 26 (affected by wind); minimum contents, 3,550 acre-ft Oct. 24 (gage height, 

0.08 ft).

1921-55: 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). e

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 1955. 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 frequentlv 

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.

MALAD RIVER BASIN 103

Big Wood Slough at Hailey, Idaho

Location. Lat 43°31'00", long 114°19'30", in sec. 9, T. 2 N., R. 18 E., on left bank 

40 ft upstream from bridge on State Highway 22, an eighth of a mile northeast of Big 

Wood River, and an eighth of a mile southwest of Hailey.

Drainage area.--See Big Wood River at Hailey on following page. 

Records available. June 1915 to September 1955.

Gage.--Water-stage recorder. Datum of gage is 5,301.17 ft above mean sea level, preliminary. Prior to Apr. 12, 1936, staff gages at or near highway bridge, at same datum.

Extremes. Maximum discharge during year, 57 cfs May 6 (gage height, 3.32 ft); maximum 

gage height, 4.24 ft Jan. 11 (ice jam); minimum discharge, 1.9 cfs May 19 (gage height, 

1.66 ft).

1915-55: Maximum discharge observed, 419 cfs June 6, 1921, from rating curve 

extended above 280 cfs; maximum gage height, 5.55 ft (top of ice in well) Jan. 20-23, 

1937; no flow at times in several years.

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

which are fair. Flow controlled at inoperative powerplant half a mile upstream to 

meet the requirements of irrigation diversion and sewage dilution. Big Wood Slough 

is a natural channel of Big Wood River and its discharge plus the discharge of Big 

Wood River at Hailey (see following page) is total discharge of river at this point.

Cooperation. Water-stage recorder inspected by employees of Water District No. 7 AB.

MALAD RIVER BASIN 

Little Wood River near Richfield, Idaho

113

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

a mile upstream from Byrns Slough and heading of Dietrich Canal, 1 mile east of railroad station at Richfield, and 14 miles downstream from Silver Creek.

Drainage area.--570 sq mi, approximately.

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

1955 except 1913, 1921).

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

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

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

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

Extremes.--Maximum discharge during year, 246 cfs Apr. 3 (gage height, 3.42 ft); maximum 

gage height, 6.32 ft Mar. 7 (ice jam); minimum discharge, 58 cfs June 10; minimum gage 

height, 2.23 ft May 13, June 10.

1911-55: Maximum discharge recorded, 868 cfs May 3, 1938 (gage height. 3.97 ft, 

site and datum then in use); minimum recorded, 7.6 cfs June 24, 25, 1920 (gage height, 

0.52 ft, site and datum then in use).

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

record, which are poor. Diversions for irrigation of about 38,300 acres above station. 

Plow partly regulated by Little Wood Reservoir (capacity, 11,700 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 

time, because of channel losses and irrigation diversions above Carey.

114 MALAD RIVER BASIN

Little Wood River at Shoshone, Idaho

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

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

from highway bridge in Shoshone.

Drainage area. 620 sq mi, approximately.

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

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

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

higher.

Extremes. Maximum discharge during year, 554 cfs May 15 (gage height, 5.28 ft); mini1922-55: Maximum discharge recorded, 673 cfs Apr. 28, 1952 (gage height, 5.24 ft, 

datum then in use); practically no flow July 29, 1931, Oct. 3, 1938.

Remarks. Records excellent except those below 40 cfs, which are fair and those for

 periods of ice effect or no gage-height record, which are poor. Diversions for irrigation of about 52,200 acres above station. Plow affected by operation of MilnerGooding 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.

Cooperation.--Two discharge measurements furnished by employees of Water District 

No. 11 AB.

1940-46).

Gage. Water-stage recorder. Altitude of gage is 2,850 ft (by barometer). Prior to 

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. 1930-55: Maximum daily discharge, 344 cfs May 23, 24, 1954; no flow or small 

flow from leakage at headgate during nonirrigation seasons and other periods when 

gates were closed.

Remarks. Records excellent. This canal, which is operated by King Hill Irrigation District to provide water for irrigation of about 10,000 acres, diverts from Idaho Power 

Co.'s canal, which in turn diverts from Malad River (Malad Springs water).

Cooperation.--Water-stage recorder graph for supplementary gage furnished by King Hill 

Irrigation District. Three discharge measurements furnished by Idaho Power Co.

Revisions (water years). WSP 723: 1930.

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

good. Flow regulated by powerplants at Lower Salmon Falls and near Bliss and many 

reservoirs above station. Practically entire flow at Milner diverted during irrigation season; flow at King Hill is then derived largely from springs and seepage 

entering below Milner. About 1,590,000 acres of land irrigated by diversions from 

river and its tributaries above station. Records of chemical analyses and water 

temperatures for the water year 1955 are given in WSP 1403.

118 CANYON CREEK BASIN

Mountain Home feeder canal near Mountain Home, Idaho

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 1955 (irrigation 

season 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, 

water-stage recorder, at site 30 ft downstream at datum 0.07 ft lower.

Extremes.--1924-29, 1931-55: Maximum daily discharge, 182 cfs Jan. 1, 1943; no flow at 

times during most years.

Remarks.--Records excellent except those below 20 cfs, which are good, and those for 

periods of no gage-height record, 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 

times when there is a surplus of water for irrigation, canal feeds directly into Mountain Home Reservoir. No diversion from canal above station. Plow regulated by headgates in Canyon Creek and by Long Tom and Little Camas Reservoirs.

Discharge, in cubic feet per second, water year October 1954 to September 1955

 2,637 60 ft); minimum observed, 474,400 acre-ft Sept. 30 (elevation, 2,601.23 ft). 

1932-55: Maximum contents observed, 1,140,000 acre-ft Apr. 15, 1952 (elevation 

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

of Sept. 30, 1955.

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

 stoFage began Oct. 16, 1932. Capacity, 1,122,000 acre-ft between elevations 2,367.5 

ft (bottom of sluice gates) and 2,670 ft (top spillway gate), 715,000 acre-ft between 

elevations 2,590.2 ft (diversion tunnel) and 2,670 ft. Dead storage below elevation 

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

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

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

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

and west of Owyhee River, and through sluice gates to river for Owyhee Canal, which 

diverts about 18 mile downstream.

140 BOISE RIVER BASIN

Arrowrock Reservoir at Arrowrock, Idaho

Location. Lat 430 36', long 115°55', in Ei sec. 13, T. 3 N., R. 4 E., at dam on Boise 

River at Arrowrock and 14 miles east of Boise.

Drainage area. 2.210 sq mi, approximately. 

Records available. October 1917 to September 1955.

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

(surveys of Bureau of Reclamation).

Extremes. Maximum contents observed during year, 292,800 acre-ft May 22, June 6 (elevation, 3,218.0 ft); minimum observed, 12,360 acre-ft Oct. 15 (elevation, 3,051.0 ft).

1917-55: Maximum contents observed, 301,200 acre-ft May 29, 1948 (elevation, 

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

gates were open and natural flow was passing through reservoir.

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

raised 5 ft in 1937; storage began in 1915. Capacity, 286,600 acre-ft between elevations 2,974 ft (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 contents 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 ft 

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

lands in Boise Valley.

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

Records available. January 1895 to September 1916 (no winter records 1904-5, 1907), 

October 1954 to September 1955. Published as "near Highland" 1905-15 and as "below 

Moore Creek, near Arrowrock" 1916.

Gage. Remote recorder records'of openings of six slide gates, one hollow-jet valve, and 

elevation of Lucky Peak Reservoir. Prior to Mar. 18, 1905, staff gages at sites about 

1 mile downstream at different datums. Mar. 18, 1905, to Mar. 20, 1915, staff gages and 

Mar. 21, 1915, to Sept. 30, 1916, water-stage recorders, at sites 5 to 7 miles upstream 

at different datums.

Average discharge. 18 years (1895-96, 1897-1903j 1905-6, 1907-16, 1954-55), 2,983 cfs 

(2,160,000 acre-ft per year).

Extremes. Maximum discharge during year, 9,860 cfs June 23; no flow Oct. 17 to Feb. 18, 

Feb. 20, during building of gate structure at Lucky Peak Dam.

1895-1916, 1954-55: Maximum discharge observed, 35,500 cfs June 14, 1896; no flow 

Oct. 17, 1954, to Feb. 18, 1955, Feb. 20, 1955.

Remarks. Records excellent except those based on engineers of watermaster's estimates, 

which are poor. Discharge measurements made 6 to 28 times per month. Daily discharge 

computed from gage ratings. Plow regulated by Lucky Peak Reservoir (see preceding 

page), Arrowrock Reservoir (see p. 140), and Anderson Ranch Reservoir (see p. 138). 

Small diversions from tributaries upstream for irrigation.

148 BOISE RIVER BASIN

Piversions from Boise River between near Boise and at Boise gaging stations, Idaho

(Formerly published as diversions from Boise River between Cowling Ranch and Boise

gaging stations, Idaho)

Between near Boise and at Boise gaging stations (prior to October 1954, 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 1947-55, 

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

Survey. Records of daily diversion for each canal from 1916 to 1955 on file In office 

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

for New York Canal. Diversion through New York Canal for period October to March as reported by Boise project, Board of Control were: October, 60,880 acre-ft, February, 

5,000 acre-ft; March, 38,090 acre-ft.

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

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

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

River.

Discharge, in cubic feet per second, April to September 1955.

Records for January 1906 to March 1907, published in WSP 272 and 370 have been found 

to be unreliable and should not be used. Published as Middle Fork Malheur River at 

Riverside, 1906-7, as Middle Pork of Malheur River above South Fork, at Riverside, 

1909-10, as Malheur River above South Fork, at Riverside, in Water-Supply Paper 370, 

1906-10, and as Malheur River at Warm Springs reservoir site, near Riverside 1914-17,

Gage.--Water-stage recorder and concrete control. Altitude of gage is 3,305 ft (by barometer). Prior to Dec. 9> 1914, staff or chain gage at several sites 3 miles downstream, 

200 ft upstream from South Fork, at various datums. Dec. 9, 1914, to July 24, 1917, 

water-stage recorder at site 1 mile upstream and 500 ft upstream from dam site at different datum. Mar. 18, 1919, to Apr. 27, 1920, staff gage at site 1 mile upstream and 

250 ft downstream from dam at different datum. Apr. 28, 1920, to Sept. 28, 1949, hook 

gage at different sites within 80 ft of present site and at present datum.

Average discharge.--36 years (1919-55), 162 cfs (117,300 acre-ft per year).

Extremes.--Maximum discharge during year, 530 cfs May 13 (gage height, 4.88 ft); no flow 

at times.

1909-10, 1915-17, 1919-55: Maximum discharge observed, 7,200 cfs (revised) Mar. 1, 

1910 (gage height, 10.7 ft, site and datum then in use), from rating curve extended 

above 820 cfs by logarithmic plotting; no flow at times.

Revisions.--The maximum discharge observed for the water year 1910 has been revised 

to 7,200 cfs Mar. 1, 1910 (gage height, 10.7 ft), superseding figure published in 

WSP 413.

Remarks.--Records good except those below 10 cfs, which are poor. Flow completely regulated since November 1919 by Warmsprings Reservoir (see p. 167). Diversions for irrigation of about 13,000 acres above station.

Revisions (water years).--WSP 833: 1936. WSP 1063: 1942-45. Revised figures of discharge, in cubic feet per second, for the water years 1909-10, and 1917, superseding

at Beulah, a quarter of a mile downstream from Agency Valley Dam and 12 miles northwest 

of Juntura.

Drainage area. 440 sq mi, approximately (revised).

Records available. June 1926 to September 1955. Published as "near Beulah" June 1926 to 

September 1935.

Gage. Water-stage recorder. Datum of gage is 3,262.20 ft above mean sea level, datum of 

1929, supplementary adjustment of 1947. June 26, 1926, to Apr. 24, 1936, water-stage 

recorder 1 mile (revised) downstream at different datum. Apr. 25, 1936, to Sept. 30, 

1949, staff gage 20 ft downstream at present datum.

Average discharge.--20 years (1935-55), 131 cfs (94,840 acre-ft per year).

Extremes. Maximum discharge during year, 358 cfs July 19 (gage height, 2.31 ft); minimum, 

0.1 cfs Jan. 21, 22.

1926-55: Maximum discharge, 7,000 cfs May 7, 1942 (gage height, 8.4 ft, from floodmark) , from computation of peak flow over dam, caused by failure of gates at Agency 

Valley Dam; no flow at times.

Remarks. Records good except those below 10 cfs, which are poor. Flow regulated by 

Agency Valley Reservoir since December 1935 (see p. 167). Diversions for irrigation 

of about 3,000 acres above station. Prior to Apr. 25, 1936, station was below intake 

of 2 diversions for irrigation of about 120 acres below station.

Revisions. Revised figures of discharge, in cubic feet per second, for the water years 

1927-32, and 1934, superseding those published in WSP 653, 673, 693, 708, 723, 738 and 

768, are given herein. Complete tables of daily discharge are given for the water

extended above 1,000 cfs; maximum gage height, 6.98 ft Mar. 26, 1952; no flow at times.

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

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 above station for irrigation of 

about 7.000 acres.

Lake Pork Reservoir near McCall, Idaho

Location. Lat 44°54', long 116°03', in NW^NW^ sec. 13, T. 18 N., R. 3 E. , on Lake Fork 

Payette River, 3 miles east of McCall.

Drainage area. 64 sq mi, approximately.

Records available. April 1926 to September 1955 (fragmentary).

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

once daily during irrigation season. Datum of gage is at mean sea level (levels bv 

Lake Irrigation District).

Extremes. Maximum contents observed during year, 19,070 acre-ft July 14 (elevation, 

5,118.34 ft); practically no storage at times during fall and winter.

1926-55: Maximum contents observed, 19,740 acre-ft June 19, 1941 (elevation, 

5,118.75 ft); no storage above elevation 5,101.0 ft for long periods during fall and 

winter of most years.

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

167940 acre-ft between elevations 5,101.0 ft (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 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 

? i of Sates - Stage in reservoir reported below 5,101.0 ft as follows: Nov. 29 

5,100.31 ft; Dec. 28, 5,099.56 ft; Feb. 3, 5,099.48 ft; Mar. 15, 5,099.37 ft- Apr 4 

5,099.22 ft; Apr. 17, 5,100.98 ft. Storage figures from gage heights as observed. '

Records available. January to December 1948 (fragmentary), January 1949 to September 1955.

Gage. Staff gage read once daily. Datum of gage is at mean sea level (preliminary, unadjusted levels of U. S. Coast and Geodetic Survey).

Extremes. Maximum contents observed during year, 404,900 acre-ft July 2, 9-14 (elevation

4.815.00 ft); minimum, 113,300 acre-ft Feb. 26-28, on basis of inflow-outflow studies ' 

1948-55: Maximum contents observed, 405,100 acre-ft June 20, 1953 (elevation

4.815.01 ft); no contents at times during March and September 1948.

Remarks. Reservoir is formed by earth-fill dam completed in May 1949. Storage began

Nov. 7, 1947. Capacity, 703,200 acre-ft between elevations 4,766 ft (4.0 ft above sill 

of outlet tunnel) and 4,828 ft (top of spillway gates). Figures herein show contents 

above elevation 4,766 ft. The Bureau of Reclamation plans to limit withdrawal to 

elevation 4,787.5 ft, retaining 50,000 acre-ft capacity as dead storage. Contents table 

computed from tables furnished by Bureau of Reclamation (revised 1950). Water is used 

for irrigation of lands in the Payette Division of the Boise project and for power at 

Black Canyon powerplant near Emmett.

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

POWDER RIVER BASIN 

Powder River near Robinette, Oreg.

Location. Lat 44°46 I 10", long 117°04'10", in E| sec. 22, T. 9 S., R. 46 E., on left bank 

2t miles northwest of Robinette and 2j miles upstream from mouth.

Drainage area. 1,660 sq mi, approximately.

Records available.--September 1928 to September 1955.

Gage. Water-stage recorder. Datum of gage is 1,937.01 ft above mean sea level, datum of 

1929, supplementary adjustment of 1947. Prior to Aug. 24, 1936, staff gage at site 

half a mile upstream at different datum. Aug. 24, 1936, to Oct. 31, 1948, staff gage 

at site 50 ft upstream at present datum.

Average discharge. 27 years, 514 cfs (372,100 acre-ft per year).

Extremes.--Maximum discharge during year, 1,870 cfs June 12 (gage height, 3.37 ft); minimum, 64 cfs Sept. 1 (gage height, 0.07 ft).

1928-55: Maximum discharge, 5,320 cfs May 28, 1948 (gage height, 6.6 ft, from 

floodmark, site then in use); minimum observed, 18 cfs Sept. 2-10, 1931.

The date of occurrence of the maximum discharge for water year 1947 has been corrected to May 8, 1947, superseding date published in WSP 1093.

diversions above station for irrigation; none below. One canal with capacity of about 

5 cfs diverts around station on left bank. Flow partly regulated by several reservoirs, the largest being Thief Valley Reservoir near North Powder (capacity, 17,400 

acre-ft).

Revisions.--WSP 1217: Drainage area. Revised figures of discharge, in cubic feet per 

second, for the water years 1929-1936, and 1949, superseding those published iri 

WSP 693, 813, and 1153, are given herewith:

a quarter of a mile upstream at different datum.

Average discharge.--27 years, 473 cfs (342,400 acre-ft per year).

Extremes.--Maximum discharge during year, 2,740 cfs May 21 (gage height, 5.05 ft); minimum, 45 cfs Jan. 4.

1928-55: Maximum discharge, 5,700 cfs May 28, 1948 (gage height, 7.06 ft); minimum 

observed, 16 cfs Nov. 22, 1931. Revisions.--The maximum discharge for the water year 1932 has been revised to 4,030 

cfs May 21, 1932 (gage height, 5.32 ft, from graph based on gage readings), superseding figure published in WSP 738.

Remarks.--Records excellent except those for periods of ice effect, which are fair. Diversions for irrigation of about 4,000 acres above station. Water is diverted above 

station from Sheep Creek and Little Sheep Creek to Grande Ronde River basin for irrigation of about 6,500 acres (revised) in Wallowa Valley.

Revisions (water years). WSP 883: 1938. WSP 1217: Drainage area. Revised figures of 

discharge, in cubic feet per second, for the water years 1929 and 1949, superseding

unadjusted. Since Jan. 31, 1952, supplementary staff gage 3 miles upstream.

Average discharge.--11 years, 10,230 cfs (7,406,000 acre-ft per year).

Extremes.--Maximum discharge during year, 56,700 cfs June 13 (gage height, 26.18 ft, from 

graph based on gage readings); minimum daily, 2,050 cfs Dec. 21,

1944-55: Maximum discharge observed, 75,300 cfs May 29, 1948 (gage height,

Lake by Silver Lake Canal and Joseph powerplant tailrace (see p. 241). City of Joseph 

diverts less than 1 cfs from Wallowa Lake for municipal supply.

DISCHARGE MEASUREMENTS AT POINTS OTHER THAN GAGING- STATIONS 303

Measurements of streamflow in the Snake River basin made at points other than regular 

gaging stations are given In the following table. Most of these measurements were made 

during periods of base flow when streamflow Is primarily from ground-water storage. Measurements believed to have been made under base-flow conditions are Identified by an asterisk (*) to the left of the discharge figure. These measurements when correlated with the 

simultaneous discharge of a nearby stream where continuous records are available will give 

a picture of the low-flow potentiality of stream. The column headed, "Measured previously 

shows the water years In which measurements were made at the same, or practically the 

same, site.

Determinations of peak flow at points other than regular gaging stations are given In 

a separate table on page 306.
