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, 1954. 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 13,050 gaging stations in the 48 States and at many 

others in the Territories of Alaska and Hawaii. On September 30, 1954, the Geological 

Survey and cooperating organizations were maintaining 6,750 gaging stations, including 

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

in the 1954 water year, most of which are published at the end of this report.

COOPERATION

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

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

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

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

Idaho: Idaho Department of Reclamation, M. R. Kulp, State reclamation engineer; 

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

7AB, M. H. Coffin, water-master.

Oregon: Office of the State Engineer, C. E. Stricklin, 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, and C. J. Bartholet, supervisor of hydraulics, succeeded by M. G. 

Walker.

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 16 gaging stations, 

of which 10 were in Idaho, 2 in Oregon, and 4 in Wyoming.

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

of the Department of Agriculture and the Bonneville Power Administration, Office of 

Indian Affairs, and the Bureau of Reclamation of the United States Department of the 

Interior.

The following organizations aided in collecting records:

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

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

Washington Water Power Co., and water-masters for Big Lost, Little Lost, Big Wood, 

Little Wood, Boise, and Weiser Rivers, Lake Fork Payette River, and Mud Lake.

Oregon: Baker, Malheur, Union, and Wallowa Counties, Pacific Power & Light 

Co., and Warmsprings Irrigation District. 

Washington: Washington Water Power Co.

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.

Control designates a feature downstream from the gage that determines the stagedischarge relation at the gage. This feature may be a natural constriction of the 

channel, a long reach of the channel, or an artificial structure.
EXPLANATION OF DATA 3

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 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 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 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 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 

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

FIGURE 1. GAGING-STATION STRUCTURES
EXPLANATION OP DATA 5

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 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 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 1954 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 

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
6 SURFACE WATER SUPPLY, 1954, PART 13

(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 

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
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 7

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 tnan 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," 

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
8 SURFACE WATER SUPPLY, 1954, PART 13

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

values 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 must 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 

for each of the 14 parts. Beginning with the reports for 1951, the records are published 

in 18 volumes, there being 2 volumes each for Parts 1, 2, 3, and 6. The boundaries of the

Note. Records for all stations in Oregon through September 1910 are contained In WSP 37O, 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 under "Miscellaneous discharge measurements" 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 Water-Supply Paper 119.

Each of the reports on the surface-water supply for the year 1939 (Water-Supply Paper 

883 for the Snake River basin) contains, for the area included in that report, a summary 

of yearly discharge at gaging stations at which 10 or more complete years of record had 

been collected. These summaries were reprinted separately.

Reports also have been published that are compilations of records for various areas, 

usually a single State or drainage basin. These reports contain records previously published {some of which may have been revised), as well as some records not contained in 

the annual series of water-supply papers. The following table contains a list of these 

reports for the area covered by this report.

HYDROLOGIC CONDITIONS

The water year 1954 was characterized by above median runoff from most of the tributaries above Idaho Falls in the Snake River basin. Below Idaho Falls the runoff from 

right-bank tributaries was above the median and runoff from left-bank tributaries was below the median. Some fairly high flows occurred during May on right bank tributaries and 

tributaries above Idaho Falls. However, the only flood of note was a cloudburst type 

flood on Wild Horse Creek, a tributary to the upper reach of Big Lost River. The drought 

In the southwestern states reached the headwaters of left-bank tributaries to the Snake 

River. Runoff from Owyhee River near Gold Creek, Nev., was only about 30 percent of the 

26-year median 1918-25, 1937-54. For two key gaging stations in the area covered by this 

report, a comparison of the monthly discharge during the 1954 water year with the median 

discharge for the 25-year period 1921-45 is shown below.

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.

SNAKE RIVER MAIN STEM 33

Snake River near Heise, Idaho

Location. Lat 43°36'45", long 111 0 39'05", in SW£ sec. 5, T. 3 N., R. 41 E., on left bank 

about 500 ft upstream from Anderson Canal headgate, 3 miles upstream from Heise, 6 miles 

east of Ririe, and 23 miles upstream from Henrys Pork.

Drainage area.--5,752 sq mi.

Records available. September 1910 to September 1954. 

Fork Snake River near Heise.

Prior to 1911, published as South

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

]T929. Prior to July 9, 1913, staff gage, and July 9, 1913, to Sept. 29, 1922, waterstage recorder, at 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 d1seharge. 44 years, 6,868 efs (4,972,000 aore-ft per year).

Extremes.--Maximum discharge during year, 30,800 ofs June 28 (gage height, 9.07 ft); minimum, 1,930 cfs Mar. 4 (gage height, 1.54 ft).

1910-54: Maximum discharge, about 60,000 efs May 19, 1927, result of washing out of 

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

1,210 efs 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 (6,080 acre-ft diverted during year), which 

diverts If 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 1954 are given in WSP 1353.

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

second, for the water year 1912, superseding those published in WSP 332, are given herewith:

SNAKE RIVER MAIN STEM 35

Diversions from Snake River between Heise and Shelley gaging stations, Idaho

Between Heise and Shelley gaging stations, 47 canals divert water from Snake River for 

irrigation; of these, 36 divert above month of Henrys Fork. Records available during each 

irrigation season from 1919 to 1954. One of the canals is equipped with a water-stage 

recorder, the others with staff gages, which are read once daily. Discharge combined to 

show total diverted flow. Records include Riley ditch, which diverts 1-| miles above 

Heise gaging station. Records good.

Extremes. Maximum discharge during year, 2,950 cfs May 22 (gage height, 5.31 ft); minimum, 217 cfs Dec. 8 (gage height, 1.60 ft).

1890-93, 1903-9, 1920-54: Maximum discharge observed, 5,830 cfs June 13, 1893 

(gage height, 6.90 ft, site and datum then in use); minimum, 215 cfs (revised) Mar. 12, 

1906 (gage height, 1.00 ft, site and datum then in use).

Revisions. The maximum discharge observed for the water year 1909 has been revised 

to 5,230 cfs June 5, 6, 1909 (gage height, 6.8 ft, site and datum then in use) and the 

minimum discharge for the water year 1906 has been revised to 215 cfs Mar. 12, 1906 

(gage height, 1.00 ft, site and datum then in use), superseding figures published in 

previous water-supply papers.

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

 40,000 acres of land irrigated from diversions above station. Water is diverted at 

times during irrigation season from Henrys Fork through Cross Cut Canal to Teton River 

three-quarters of a mile above station (11,750 acre-ft diverted into river during 1954 

irrigation season).

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

 second, for the water years 1903-6, 1908-9, superseding those published in WSP 100, 

135, 178, 214, 252 and 272 are given herewith. Figures of daily discharge for the 

periods Nov. 12, 1903, to Feb. 25, 1904, Dec. 1-13, 1904, Jan. 1 to Feb. 28, 1909, 

published in WSP 100, 135 and 272 are considered to be in error due to failure to consider backwater effect from ice. These records should not be used.

Diversions from Teton River between St. Anthony gaging station and mouth, Idaho

Between St. Anthony gaging station and mouth, 19 canals divert water from Teton River 

for irrigation of 30,000 acres of land. Records available for part of each irrigation 

season from 1919 to 1954. Discharge of canals computed from daily or twice-weekly staffgage readings, or interpolated, and combined to show total diverted flow. Records good.

Discharge, In cubic feet per second. May to September 1954

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

Average discharge. 23 years (1931-54), 154 cfs (111,500 acre-ft per year).

Extremes. Maximum discharge during year, 466 cfs Oct. 24 (gage height, 4.75 ft); minimum, 

4 cfs July 15, Aug. 19, 31.

1913-54: Maximum discharge, 868 cfs May 21, 1921; no flow for many days.

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

which are fair. 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.

DIVERSIONS FROM SNAKE RIVER BETWEEN GOOSE CREEK AND SNAKE RIVER AT MILNER 71

Gooding Canal at Milner, Idaho

Location.--Headgates of canal, lat 42°31', long 114°01', in sec. 28, T. 10 S., R. 21 E., 

at Milner Dam.

Records available. May 1930 to September 1954.

Gage. Water-stage recorder on Milner-Gooding Canal at site 3 miles downstream from headgates. Staff gage on A lateral l| miles downstream, and differential recorder on control gates of diversion 3 miles downstream from headgates.

Average discharge. 19 years (1935-54), total 975 cfs; Milner-Gooding project, 560 cfs; 

North Side Canal Co. project, 415 cfs.

Extremes. Maximum daily discharge during year, 2,610 cfs July 14, 15, 20; no flow for 

many days.

1930-54: Maximum daily discharge, 2,740 cfs Aug. 2, 1953; no flow for many days.

Remarks. Records good. Gooding Canal diverts water from Snake River for Milner-Gooding 

project of Bureau of Reclamation and in part for project of North Side Canal Co. The 

latter project also receives water through the North Side Twin Falls Canal and P. A. 

lateral. Discharge of canal is computed by combining the discharge of Milner-Gooding 

diversion and that of North Side Canal Co. diversions below their division point and 

adding 35 cfs to that sum for loss between headgates and division point.

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

Reservoir District No. 2.

98 MUD LAKE-LOST RIVER BASINS

Mud Lake near Terreton, Idaho

Location . La t 43°53', long 112 0 24', in SW£ sec. 1, T. 6 N., R. 34 E., 2 miles north of 

First Owsley pumphouse, 2| miles northeast of Terreton, and 14 miles southwest of 

Hamer.

Drainage area. --1,050 sq mi, approximately, not including Medicine Lodge Creek.

Records available. April 1921 to September 1954.

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

Prior to Oct. 31, 1931, staff gages at or near pumphouse (now used as supplementary 

gage) at same datum.

Extremes. --Maximum contents during year, 33,100 acre-ft Apr. 21-23; maximum gage height, 

7.10 ft Apr. 22; minimum contents, 3,200 acre-ft Sept. 3 (gage height, -0.12 ft).

1921-54: Maximum contents observed, 61,660 acre-ft May 5, 1923 (gage height, 9.20 

ft); practically no contents Oct. 1 to Nov. 15, 1937, due to bypassing Camas Creek (see 

Remarks ) .

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

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

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

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

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

to First Owsley pumping plant. Bypass was not used during 1954. 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.

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

Extremes. Maximum contents observed during year, 40,220 acre-ft June 30 (gage height, 

63.40-ft); minimum observed, 3,780 acre-ft Sept. 30 (gage height, 20.10 ft).

1919-54: Maximum contents observed, 42,390 acre-ft May 30, 1951 (gage height, 

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

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

Remarks.--Reservoir is formed by earth-and rock-fill dam, which was reconstructed in 1917- 

18; storage impounded by original dam not recorded. Capacity is 38,400 acre-ft between 

gage heights 7.0 ft (bottom of outlet tunnel) and 62.0 ft (crest of spillway). Dead 

storage reported to be about 125 acre-ft. Water is used for irrigation of about-33,000 

acres in Big Lost River irrigation district. About 9,000 acres irrigated from Big Lost 

River and tributaries above reservoir. Considerable seepage around dam because of its 

porous foundation, but the greater part of this water returns to Big Lost River between 

reservoir and station below reservoir, near Mackay. Figures given herein represent 

usable contents.

120 MALAD RIVER BASIN

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 (revised) 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 1954.

Qage. 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. 73 cfs Apr. 15 (gage height, 3.71 ft); maximum 

gage height, 3.87 ft Jan. 13 (ice jam); minimum discharge, 0.8 cfs Dec. 26 (gage height, 

1.47 ft).

1915-54: 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.

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. Prior to 

May 21, 1954, at site 500 ft downstream.

Drainage area. 570 sq mi, approximately.

Records available. January 1911 to September 1954 (no winter records).

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

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

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

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

Extremes. Maximum discharge during year, 211 cfs Nov. 20 (gage height, 1.99 ft, site and 

datum then In use); minimum recorded, 54 cfs May 10, 17; minimum gage height recorded, 

1.22 ft May 10.

1911-54: 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 good. Diversions for irrigation of about 38,300 acres above station. 

Flow partly regulated by Little Wood Reservoir (capacity, 11,700 acre-ft), Fish Creek 

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

because of channel losses and Irrigation diversions above Carey.

Cooperation.--Water-stage-recorder graph and two discharge measurements furnished by 

Water District No. 11 AB.

King Hill Canal near Hagerman, Idaho

Location. Lat 42°52', long 114°55', in SWtr sec. 27, T. 6 S., R. 13 E., on left bank above 

entrance to inverted siphon crossing Snake River, half a mile west of highway bridge 

over Malad River and 3f miles north of Hagerman.

Records available.--March 1930 to September 1954 (irrigation seasons only, 1930-37, 

1940-45).

__.--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.--1930-54; 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).

134 SNAKE RIVER MAIN STEM

Snake River at King Hill, Idaho

Location. Lat 43*00', long 115 0 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 1954.

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 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, 19,100 cfs May 30 (gage height, 9.88 ft); minimum, 1,810 cfs Jan. 19 (gage height, 2.43 ft); minimum daily, 6,740 cfs May 20.

1909-54: 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 Palls and near 

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

during most irrigation seasons; flow at King Hill is then derived largely fro.Ti 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 1954 are given in WSP 1353.

154 BOISE RIVER BASIN

Arrowrock Reservoir at Arrowrock, Idaho

Location. Lat 43°36', long 115°55', in E| sec 

Arrowrock, 22 miles by road east of Boise.

Drainage area. 2,210 sq mi, approximately. 

Records available.--October 1917 to September 1954.

Gage. Staff graduated on face of dam read once daily, 

(surveys of Bureau of Reclamation).

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

Datum of gage is at mean sea level

Extremes.--Maximum contents observed during year, 294,700 acre-ft June 27 (elevation, 

3,218.6 ft); minimum observed, 12,320 acre-ft Oct. 15 (elevation, 3,050.9 ft).

1917-54: 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.

BOISE RIVER BASIN 

Diversions from Boise River between Boise and Notus gaging stations, Idaho

163

Between Boise and 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 diversion covering period April to September for years 

1947-54 in reports of Geological Survey. Records of daily diversion for each canal from 

1916 to 1954 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. Records fair.

BOISE RIVER BASIN 165

Boise River basin winter drainage investigation

The winter season drainage conditions in Boise Valley are pertinent to investigations 

of feasibility of developing additional irrigation water supplies by diverting the winter 

flow of certain drains to storage reservoirs or by pumping from wells located within the 

irrigated tract during the irrigation season. Board of Control and River Watermaster records provide information concerning drain discharges and canal diversions during the 

irrigation season. The watermaster applies these data to the river station discharge 

records to determine losses and gains in river channel during summer operations. Little 

detail is available other than the overall differences between flows recorded at river 

gaging stations during the winter season.

On Jan. 25, 1954, two field runs of the "spot type" were made. One of these included 

discharge measurements at points where nine south side drains crossed the Phyllis Canal. 

These, combined with the river flow below that canal heading, are compared with January 

averages recorded in 1936, 1937, and 1938, showing the current status of those sources 

of supplemental water supply via winter season storage, which were investigated 1936-38. 

The other field run included Boise River measurements to define gains and losses in some 

10 successive channel reaches between the mouth of Moore Creek 4 miles downstream from 

Arrowrock Dam and the confluence with Snake River some 69 miles downstream. Stock water 

diversions through irrigation canals were measured in each section; also, drain ditch and 

other miscellaneous tributary flows entering the river. The locations of the measuring 

points were reviewed in the field and several results confirmed by repeat measurements on 

the days following.

During the period of the investigation, the valley lands were drier than usual for the 

time of year with no snow accumulated on the ground. The Arrowrock Reservoir and the New 

York Canal diversion gates were closed Dec. 5, 1953, to Feb'. 15, 1954. No releases were 

being nade from Deer Flat Reservoir and no diversion was being made from Wilson and 

Elijah drains via siphon to the north side Notus unit. Monthly precipitation at Boise 

was below normal during both December and January. The small side streams were contributing very little to the valley area proper.

Discharge measurements on Boise River and drains crossing Phyllis Canal to Boise River, Idaho, 

Jan. 25, 1954, versus corresponding January mean flows 1936, 1937, and 1938

Extremes. Maximum discharge during year, 740 cfs May 11 (gage height, 5.30 ft); minimum 

recorded, 2 cfs. Oct. 18, 19 (but may have been less during period of backwater from 

beaver dam).

1906-17, 1919-54: Maximum discharge observed, 5,490 cfs Mar. 2, 1910 (gage height, 

10.7 ft, site and datum then in use, from rating curve extended above 820 cfs; no flow 

at times.

Remarks .--Records good except those below 10 cfs, which are poor. Plow completely regulated 

since November 1919 by Warmsprings Reservoir (see p. 173). Diversions for irrigation of 

about 16,000 acres above station.

Revisions (water years).--WSP 833: 1936. WSP 1063: 1942-45.

182 PAYETTE RIVER BASIN

Lake Fork Reservoir near MoCall, 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 MoCall.

Drainage area. 64 sq mi, approximately.

Records available. April 1926 to September 1954 (fragmentary).

Gage. 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 by 

Lake Irrigation District).

Extremes.--Maximum contents observed during year, 19,140 acre-ft June 22-24, 26 (elevation, 

5,118.38 ft); practically no storage at times during fall and winter.

1926-54: 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, 

16,940 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 of 

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

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

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

elevation of sill of gates. Stage in reservoir reported below 5,101.0 ft as follows: 

Jan. 21, 5,099.85 ft; Feb. 25, 5,100.16ft. Storage figures from gage heights as observed.

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

downstream from Pall Creek, 2-g- miles northeast of French Creek Post Office, and 16 

miles east of Riggins.

Drainage area. 12,270 sq mi, approximately. 

Records available.--October 1944 to September 1954.

Gage. Staff gage read once daily. Datum of gage is 1,908.92 ft above mean sea level, 

unadjusted. Since Jan. 13, 1952, supplementary staff gage 3 miles upstream.

Average discharge.--10 years, 10,400 cfs (7,529,000 acre-ft per year).

Extremes. Maximum discharge during year, 62,300 cfs May 21 (gage height, 23.70 ft, 

supplementary gage, from graph based on gage readings); minimum observed, 2,440 cfs 

Jan. 13 (gage height, -0.52 ft, supplementary gage).

1944-54: Maximum discharge observed, 75,300 cfs May 29, 1948 (gage height, 33.50 ft); 

minimum observed, 1,790 cfs Dec. 27, 1952 (gage height, -1.30 ft, supplementary gage).

Remarks.--Records excellent except those for periods of ice effect or doubtful gage-height 

record, which are good. Amount of water diverted above station for irrigation is a 

negligible percentage of total flow.

MISCELLANEOUS DISCHARGE MEASUREMENTS 287

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. 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.

Determinations of peak flow at points other than regular gaging stations are given in 6. 

separate table on page 291.
