SURFACE WATER SUPPLY OF SNAKE RIVER BASIN, 1943

SCOPE OF WORK

This volume Is one of a series of 14 reports presenting results' of measurements of , 

stage and flow made on streams, lakes,.and reservoirs In the United States during the 

water year ending September 30, 1943. The work was begun In 1888 in connection with, 

special studies relating to Irrigation. Measurements of the flow of streams and of the 

stage and contente of lakes and reservoirs have been made at about 9,670 gaging stations 

In the 48 States and also at many In the Territories of Alaska and Hawaii. In July 1943, 

5,130 gaging stations, Including those In Hawaii, were being maintained by the Geological 

Survey and cooperating organizations. Miscellaneous discharge measurements were made 

during the water year at many other points.

In the execution of the work many State and private organizations have cooperated, 

either by furnishing data or by aeslstlng In collecting data. Cooperation of the first 

kind Is acknowledged In connection with the description of each station affected; cooperation of the second kind Is acknowledged, under the heading "Cooperation," In the introductory matter that precedes the gaging-etatlon records in each volume. In the present 

volume, the section on cooperation, of the second kind appears on page 12.

- DEFINITION OF TERMS

The unite In which etream-flow data are presented in this report and other terms used 

herein are defined as follows:

"Second-feet" Is an abbreviation for "cubic feet per second." A second-foot Is the 

rate of discharge of a stream whose channel is 1 square foot in cross-sectional area and 

whoee average velocity le 1 foot per second.

"Second-feet per equare mile" Is the average number of cubic "feet of water, flowing per 

second from each square mile of area drained, on the aesumptlon that the runoff Is distributed uniformly both as regards time and area.

"Runoff in Inches" is the depth to which ah area would be covered if all the water 

draining from-it In a given period were uniformly distributed on Its surface. It is- used 

for comparing runoff with rainfall, which is usually expressed in inches.

An "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 connection with 

storage for Irrigation.

"Second-foot-day" is the volume of water represented by a flow of 1 second-foot for 24 

hours. It le 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 an abbreviation for the term "relation between gage 

height and discharge."
2 SURFACE WATER SUPPLY, 1943, PART 13

"Control" Is a term used to designate a. feature downstream from-the gage that determines 

the stage-discharge relation at the gage. This feature may be a natural section, a reach 

of the channel, or an artificial structure.

"Contents" Is a term applied to the volume of water In a reservoir, not Including water 

In bank storage unless so Indicated.

EXPLANATION OF DATA

The base data collected at gaging stations consist of records of stage, measurements of 

discharge, and general information used to supplement the records of stage and discharge 

measurements In determining the daily flow. The records of stage are obtained either from 

direct readings on a nonrecordlng gage or from a water-stage recorder that gives a continuous record of the fluctuations. Measurements of discharge are made with a current 

meter by the general methods outlined In standard textbooks on the measurement of river 

discharge. Typical structures In use at gaging stations are shown In figure 1.

Rating tables giving the discharge for any stage are prepared from the discharge1 measurements. The application of the dally mean gage height to these rating tables gives the 

daily mean discharge, from which the monthly and the yearly mean discharge are computed. 

If the-stage-discharge relation is subject to change because of frequent or continual 

change in the physical features that form the control, the daily mean discharge is 

determined by the "shifting-control method," In which correction factors based on individual discharge measurements and notes by engineers and observers, are used in applying the 

gage heights to the rating tables. At times the stage-discharge relation for a station 

may be temporarily changed by the presence of aquatic growth or debris on the control. 

For such times the daily mean discharge is computed by what Is essentially the "shiftingcontrol" method, described above.

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

reservoirs, tributary streams, or other sources, which necessitates the use of the "slope 

method," in which the slope or fall in a reach of the stream Is a factor in the determination of discharge. Information requisite for determining the slope or fall is obtained 

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

the stage-discharge relation Is affected by changing stage, and for them the rate of 

change of 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, which makes it impossible to compute the discharge In the usual manner. Discharge for ceriods of Ice effect Is computed on the basis of the gage-height record and 

occasional winter discharge Tneasurements, consideration being given to the available information on temperature and precipitation, notes by gage observers and engineers, and 

comparable records of discharge for stations in the same or nearby basins. The days 

Included In tne periods of ice effect and- the days during the winter period on which discharge measurements were made are Indicated in the table by symbols referring to footnotes 

or are given In a general note following the table.

For most of the gaging stations on streams In the area covered by this report the data 

presented comprise a description of the station, a table showing the dally discharge of

the stream, and a table of monthly and yearly discharge and runoff. Skeleton rating 

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

greater part of the year was determined by the shifting-control method, the slope method, 

or other special methods.

The description of the station gives the type of gage; its latitude and longitude as 

determined from the best available maps, and information In regard to diversions that 

decrease the flow at the gage, artificial regulation from pondage or storage, and the 

accuracy of the records. Under "Average discharge" is given £he average discharge for the 

number of years indicated. It is given only for stations for which there are 10 or more 

complete years of record. Under "Extremes" are given the maximum discharge and gage 

height; the minimum discharge if there is little or no regulation; the minimum dally discharge if there is extensive regulation (also the minimum discharge if useful); and the 

minimum gage height (unless It Is of no importance). Unless otherwise qualified, the 

maximum discharge corresponds to the crest stage, obtained by use of a water-stage 

recorder or a nonrecordlng gage read at the time of the crest. Likewise the minimum discharge represents the lowest stage, unless otherwise qualified, selected peak discharges 

with the timc<? of their occurrence are glven,below the table of monthly discharge, for some 

stations. This supplementary Information is generally omitted for a station at which the 

drainage area of the etream is less than 10 or more than 10,000 square miles or at which, 

on most days, the peak discharge exceeds the mean discharge by less than 10 percent.

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

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

dally 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 in 

second-feet corresponding to once-daily readings of the gage or the mean of twice-daily 

readings. For periods of rapidly changing stage the dally mean discharge is determined 

from gage-height graphs based on gage readings made once or twice dally or oftener, as 

stated in the station description.

In the table of monthly discharge the column headed "Second-foot-days" gives the sum 

for each month of the figures given In the table of daily discharge. The column headed 

"Maximum" gives the maximum daily discharge, not the momentary discharge when .the water 

surface wae at crest stage. Likewise, In the column headed "Minimum" the quantity given 

is the minimum dally discharge. The column headed "Mean" gives the average flow in cubic 

feet per second during the month.

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

a table showing daily contents is given. A skeleton table of capacity at given stages Is 

usually given in the first report In which data for a station are published but is omitted 

from succeeding reports.
SURFACE WATER SUPPLY,- 1943, PART 13 5 

TIME BASIS

At 2 a.m. on February 9, 1942, as an emergency measure, the Nation shifted from 

standard time to "war time," and clock time in the several zones of the country was moved 

ahead 1 hour, or to 3 a.m. Records of daily discharge prior to February 9, 1942, were 

computed on the basis of standard time. Records subsequent to that date have been computed 

on the basis of war time. To convert war time to standard time, subtract 1 hour.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

»

The accuracy of stream-flow data depends primarily on (1) the permanency 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 flow, and interpretation of 

records.

The station description gives a statement in regard to the general 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 accurate than the daily records.

Yield at some stations as indicated by monthly means may vary widely from natural yield, 

owing to diversion, consumption, regulation by storage, increase or decrease in evaporation 

due to artificial causes, or other factors. For such stations figures of "second-feet per 

square mile" and "runoff in inches" are not published unlsss storage or diversion records 

are included indicating 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 its inclusion is indicated. Figures of second-feet 

per square mile and runoff in inches are also'omitted if the drainage area includes large 

noncontributing areas or If the average annual rainfall over the drainage area is less 

than 20 inches.

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 show the water supply available for further development, as prior appropriations 

below the station must first be satisfied.

The table of monthly discharge presents in summary the distribution of the flow past 

the station. The table of daily discharge a/fords opportunity for more detailed studies 

of the variation in flow. As further observations in each succeeding year may be expected 

to throw-new light on data previously published, it should be borne in mind that such data

are subject to revision in succeeding water-supply papers.

Papers on surface water supply containing records from 1899 to date, grouped by years 

and drainage basins, are listed by number on page s. The data for any particular 

station will, In general, be found in the reports covering the years during which the 

station was maintained. For example, the data for 1910 to 1920 for any station In the 

area covered by part 3 are published In Water-Supply Papers 283, 303, 323, 353, 403, 433, 

453, 473, and 503, which .contain records for the Ohio River Basin for those years.

The records at most of the stations discussed in these reports extend over a series of 

years . Miscellaneous measurements at many points other than regular gaging stations have 

been made each1 year and are published under "Miscellaneous discharge measurements" at the 

end of each report, the streams and points of measurement listed appearing in the same 

relative order as the streams and gaging stations in the body of the report. An Index of 

the records obtained prior to 1904 has been published in Water-Supply Paper 119.

Each of the reports on surface water supply for the year 1939, issued as Water-Supply 

Papers 871 to 884 (see table on p. 8 ), contains a eummary of yearly discharge at gaging 

stations In the area covered by that report. Gaging stations at which 10 or more complete years of record have been collected are represented. These summaries are available 

also as separate reprints.

Location.- Electric tape gage, lat. 43°51', long. 110°35', In sec. 18, T. 45 N., R. 114

 W., at dam on Snake River, at Moran. Datum of gage is at mean sea level (levels by 

Bureau of Reclamation).

Drainage area.- 816 square miles.

Records available.- July 1908 to September 1943 (1908-10, fragmentary).

Extremes.- Maximum contents during year, 854,150 acre-feet July 2, 10, 21-23, 29 (eleva-

 lion, 6,769.28 feet); minimum, 321,540 acre-feet Oct. 1 (elevation, 6,746.74 feet). 

1908-43: Maximum contents, 857,220 acre-feet June 23, 1937 (elevation, 6,769.40 

feet); no usable contents several days In period August to October 1919 (elevation, 

6,730.00 feet). ,

Remarks.- Reservoir was formed by log crib dam In 1906 with a usable capacity of 300,000

 acre-feet. The dam washed out In July 1910 and was replaced by an earth dam, forming 

a reservoir with a- usable capacity of 380,000 acre-feet. The earth1 dam was raised In 

1916 Increasing the usable capacity to 790,000 acre-feet. In 1917, by dredging the 

outlet, the capacity was further Increased to 847,000 acre-feet between elevations 

6,730 feet (top of baffles In sluices) and 6,769 feet (top of spillway gates). Water 

Is used for Irrigation In Snake River Valley, Idaho. Gage read once dally at 8 a.m. 

Contents as given herein are computed from elevation at that time; all available for 

release.

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

4,062 feet (from river-profile map).

Records available.- May 1909 to September 1943.

Extremes.- Maximum discharge during year, 23,100 second-feet June 6 (gage height, 20.10

 minimum, ,12 second-feet July 27-30; - minimum gage height, ,1.56 . feet July 28-30. 

1909-43: Maximum discharge, 44,400 second-feet June 12, 1909 (gage height, 20.10 

feet, site and datum then in use); minimum, 2 second-feet Mar. 17-28, 1936 (gage 

height, 1.18 feet).

Remarks.- Records excellent except those for period July 19 to Aug. 19, which are fair. 

Flow regulated by American Falls Reservoir (see p. 21), Lake Walcott (see p. 24) 

and other reservoirs having a combined usable capacity of about 3,300,000 acre-feet, 

and greatly reduced by dlversionsabove Mllner Dam for irrigation. About 1,300,000 

acres of land irrigated by diversion from river and tributaries above station. Flow 

includes some stored water released for use downstream by Idaho Power Co.

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

feet, site and datum then in use), from rating curve extended above 20,000 secondfeet; minimum, undetermined leakage through Twin Falls power plant at times since 

Nov. 23, 1935.

Remarks.- Records excellent except those above. 18,000 second-feet and those for periods 

ot no gage-height record, which are fair. Flow regulated by Twin Falls power plant and 

many reservoirs above station. Practically entire flow is diverted at Milner during 

irrigation season; no diversions between Milner and Kimberly.

Snake River at King Hill, Idaho

Location.- Water-stage recorder, lat. 43°00', long. 115°11', in SWi sec. 7, T. 5 S., 

R. HE., 300 feet east of railroad station at King Hill and 20 miles downstream from 

Big Wood River.

.Records available.- May 1909 to September 1943.

Extremes.- Maximum discharge during year, 31,000 second-feet June 7 (gage height, 13.06 

reet); minimum, 7,370 second-feet May 25 (gage height, 5.Q5 feet).

1909-43: Maximum discharge observed, 47,200 second-feet June 22, 1918 (gage height, 

16.3 feet), from fating curve extended above 30,000 second-feet; minimum observed, 

4,760 second-feet July 7-9, Aug. 15, 16, 1910 (gage height, 4.5 feet).

Remarks.- Records good. Plow regulated by many reservoirs above station. Practically 

entire flow at Milner diverted during irrigation season so that flow at King Hill is

Location.- Electric tape gage, lat. 44°25', long. 111°24', in gate house shaft at dam 

on Henrys Fork, a quarter of a mile south of quarter corner between sees. 28 and 29, 

T. 13 N., R. 43 E., a quarter of a mile upstream from Buffalo River, and 2 miles west 

of Island Park. Datum of gage is at mean sea level (levels by Bureau of Reclamation).

Drainage area.- 478 square miles.

Records available.- November 1938 to September 1943.

Extremes.- Maximum contents observed during year, 136,340 acre-feet ffey 30 (elevation, 

6,303.14 feet); minimum observed, 60,535 acre-feet on several days in October and 

November (elevation, 6,291.32 feet).

1938-43: Maximum contents observed, 137,230 acre-feet my 29, 1942 (elevation, 

6,303.25 feet); minimum observed after first filling of reservoir, 16,855 acre-feet 

Sept. 27, 1940 (elevation, 6,274.22 feet).

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

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

outlet gates open) arid 6,302 feet (crest of spillway). Natural flow passing through 

reservoir when outlet gates are open prevents withdrawal of storage to elevation 6,230 

feet (sill of lower outlet). Dead storage negligible. Water is used for irrigation 

in Fremcnt-I&dison irrigation district between Ashton and Rexburg,. Gage read at 8 a.m. 

Contents given herein are computed from elevations at that time; all available for 

release.

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

BIO LOST RIVER BASIN 69

Big Lost River (west channel) above Mackay Reservoir, near Mackay, Idaho

Location.- Water-stage recorder, lat. 43°58', long. 113°45', In sec. -5, T. 7 N., R. 23 

£., above flow line of reservoir, 3 miles upstream from Mackay Dam, and 7& miles northwest of Mackay.

Recorde available.- May 1919 to September 1943. 

Average discharge.- 24 years, 57.6 second-feet.

Extremes.- Maximum discharge during year, 376 second.-feet June 20; maximum-gage height, 

a. 71 reet May'31; minimum discharge, 34 second-feet Apr. 9-13, 15, 16 (gage height. 

1.96 feet).

1919-43: Maximum discharge, 1,200 second-feet (estimated) sometime during period

« June 5-16, 1921 (gage height, 4.45 feet, site and datum then in use): minimum, 9 

second-feet May 22, 26, 1935.

Remarks.- Records good except those for June to August, which are fair. Diversions above 

station for irrigation. The sum of the combined discharge of east and west channels 

of Big Lost River and the combined discharge of east and west channels "of Warm Spring 

Creek, near Mackay, represents practically the entire surface flow of Big Lost River 

which enters Mackay Reservoir (see following page).

88 TRIBUTARIES AND DIVERSIONS BETWEEN PORTNEUF RIVER AND SALMON FALLS CREEK

South Side Twin Falls Canal at Mllner, Idaho

Location.- Water-stage recorder, lat. 42°31", long. 114°01', In sec. 29, T. 10 S., R. 21 

is.1 ., YUO feet downstream from head gates at Mllner Dam.

Records available.- May 1909 to September 1943.

Extremes.- Maximum discharge during year, 3,670 second-feet July 31 (gage height, 10.33 

feet); minimum dally, 35 second-feet (estimated by observer) Oct. 26-29.

1909-43:' Maximum dally discharge, 4,600 second-feet Aug. 12, 1918, computed on 

basis of stage-discharge relation for canal plus estimates by hydrographer of water 

wasted through spillway below station and returned to river; no flow Sept. 20, 1920.

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

record, which are fair. Flow controlled by head gates. Canal diverts water from 

Snake River at Milner Dam for Irrigation of 202,000 acres of land In Twin Falls 

County.

Cooperation.- Gage-height record and one discharge measurement furnished by Twin Falls 

uanai co.

TRIBUTARIES AND DIVERSIONS BETWEEN PORTNEUF RIVER AND SAIGON FALLS CREEK 89 

Rock Creek near Twin Falls, Idaho

Location.- Water-stage recorder, lat. 42°36', long. 114°32', in SWi sec. 36, T. 9 S., 

RT~IB~E., at highway bridge, 3 miles upstream from mouth and 4 miles northwest of 

town of Twin Falls.

Records available.- March 1922 to September 1943. 

Average discharge.- 21 years, 211 second-feet.

Extremes.- Maximum discharge during year, 410 second-feet June 13 (gage height, 3.02 

reetj; minimum, 130 second-feet Feb. 10, 11 (gage height, 1.94 feet).

1922-43: Maximum discharge, 984 second-feet Sept. 21, 1927 (gage height, 4.5 feet, 

datura then in use. from floodmarks); minimum, 90 second-feet Mar. 28, 1941 (gage 

height, 1.66 feet).

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

poor. Practically all normal summer flow diverted several miles above station for 

irrigation. Waste water from South Side Twin Falls low-line canal, which crosses Rock 

Creek*12 miles above station, causes abrupt fluctuations in stage at times. Irrigation 

waste water and return flow from project lands enter above gage.

Location.- Graduations on upstream face of dam on Boise River, lat. 43°36', long. 

115°55', in Ei sec. 13, T. 3 N., R. 4 E., at Arrowrock, 22 miles by road east of 

Boise. Datum of gage is at mean sea level (surveys of Bureau of Reclamation).

Drainage area.- 2,210 square miles.

Records available.- October 1917 to September 1943.

Extremes.- Maximum contents observed during year, 300,300 acre-feet July 8, 9 (elevation, 

3,218.8 -feet); minimum contents not determined; no usable contents Oct. 18, 19, When 

sluice gates were open.

1917-43: Maximum contents observed, 300,900 acre-feet May 4, 5, 1939 (elevation, 

3,219.0 feet); no usable contents during period in each of several years when sluice 

gates were open.

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

raised 5 feet in 1937; storage began in 1915. Capacity, 291,600 acre-feet between 

elevations 2,956 feet (11 feet below center line of sluice gates, 8.5 feet below sill) 

and 3,216 feet (crest of movable spillway at highest position). Dead storage, 

negligible. Figures given herein represent total contents (including bank storage), 

which, project officials state, may have been reduced as much as 5,000 to 6,000 acrefeet by the deposition of silt. Water is used for irrigation of lands in Boise Valley. 

Gage read once daily about 8 a.m.

1940-43: Maximum discharge, that of Apr. 20, 1943; minimum, that of Dec. 16, 1942.

Remarks.- Records good except those for periods of no gage-height record and those for

 month of April, which are fair. Flow regulated by Arrowrock Reservoir (see p. 128). 

New York, Rldenbaugh, and several smaller canals divert between Moore Creek and this 

station. Small amount of water from cottonwood Oulch enters between original and 

present site but records are considered to be comparable.

PAYBTTE RIVER BASIN 153

Deadwood River below Deadwood Reservoir, near Lowman, Idaho

Location.- Water-stage recorder, lat. 44°18', long. 115°39', in NEi sec. 17, T. 11 N.,

 IT. 7 E., 300 feet upstream from Wilson Creek, a quarter of a mile downstream from 

Deadwood Dam at lower end of Deadwood Basin, 15 miles north of Lowman, and 18 miles 

upstream from mouth.

Drainage area.- 108 square miles.

Records available.- October 1926 to September 1943.

Average discharge.- 16 years (1927-43), 188 second-feet.

Extremes.- Maximum discharge during year, 1,740 second-feet June 1 (gage height, 5.46 feet}, from rating curve extended above 1,200 second-feet; minimum not determined, 

occurred when gates at dam were closed.

1926-43: Haximum discharge, 2.150 second-feet May 26, 1928 (gage height, 5.67 feet, 

site and datum then in use); small amount of leakage from reservoir for long periods 

during 1930-43 when gates 19 dam were closed.

Remarks.- Records good except those below 5 second-feet, which are poor. Flow regulated

 since' Nov. 2, 1930, by Deadwood Reservoir (see preceding page). During late fall of 

1936 the Bureau of Reclamation cut an intermountain canal to divert a small flow from 

a tributary of Johnson creek in Salmon River Basin to Deadwood River Basin for supplemental storage in Deadwood Reservoir. Discharge measurements or field estimates made 

on June 12, July 13, Sept. 6, 1943, indicate flow in this canal of 25, 12.6, and 1.5 

second-feet, respectively.

Discharge, in second-feet, water year October 1942 to Sept either 1643

Records available.- August 1921 to September 1943. 

Average discharge.- 22 years, 366 second-feet. 

Extremes.- Maximum discharge during year, 3,400 second-feet June 1 (gage height, 4.63

feet;; minimum, 33 second-feet Nov. 21 (gage height, 0.84 foot); minimum dally,' 40

sjecond-feet Jan. 18.

1921-43: Maximum discharge, 4,230 second-feet May 9, 1928 (gage height, 5.17 feet),

from rating curve extended above 3,200 aecond-feet; minimum, 28 second-feet Nov. 4,

1935 (gage height, 0.83 foot); minimum dally, 34 second-feet Nov. 4, 1935. 

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

which are fair. Flow regulated by Deadwood Reservoir (see p.152). Small amount of

water diverted from tributary of Johnson Creek In Salmon River Basin to Deadwood River

Basin during year. 

Correction.- The minimum dally discharge during January 1942 was not determined; the

figure published In Water-supply Paper 963 Is In error.

PAYETTE RIVER BASIN 166

Payette Lake at McCall, Idaho 

(Formerly published as Payette Lake at Lardo, Idaho)

Location.- Staff gage, lat. 44°55', long. 116°07', In sec. 8, T. 18 N., R. 3 E., at out- 

 let of lake on North Fork Payette River, at McCall. Datum of gage Is 4,982.24 feet 

above mean sea level, adjustment of 1912.

Drainage area.- 131 square miles.

Records available.- August 1921 to September 1943 (fragmentary).

Extremes.- rfexlmum gage height observed during year, 8.13 feet July 23; minimum observed,

1921-43: Miximum gage height observed, 8.75 feet July 13,*1935; minimum observed, 

0.95 foot Oct. 3, 1931.

Remarks.- Elevation of Payette Lake Is regulated within natural rangs by a structure conslstlng of a series of concrete-filled cribs supporting removable flashboards, completed in 1923. Some regulation Is reported to have been effected by timber flashboards for several earlier years. Lake area Is approximately 5,000 acres and no 

capacity table has been developed. Water Is used for Irrigation of lands In vicinity 

of Emmett. No diversion above station. Because of draw-down In outlet channel, 

stages at the gage are slightly lower at times than stages of lake.

Coo ration.- Gage-height record furnished by Forest Service supplemented during period1 

flay 9 to Aug. 11 by observations by employee of Payette Valley Water Users Association 

and Bureau of Reclamation.

» Winter discharge measurement made on this day.

a No gage-height record; discharge computed on basis of auxiliary record at power plant.

o Stage-discharge relation indefinite because of backwater from reservoir; discharge computed on 

basis of special gage-height computation developed from auxiliary gage-relation curve.

Hote.- Float restrained by Ice in well Dec. 3-8, Dec. 16 to Apr. 5; discharge interpolated Dec. 

3-8 and computed on basis of auxiliary record at power plant Deo. 16 to Apr. 5.

Time baaIs« Mountain war time. To convert war time to standard time, subtract 1 hour.
PAYETTE RIVER BASIN 

Lake Fork Reservoir near McCall, Idaho

161

Location.- Staff gage and graduations on concrete gate-control structure of dam on Lake 

 FoTTTayette River, lat. 44°54', long. 116°03', in NWiNWi sec. 13, T. 18 N., R. 3 E.,

3 miles east of McCall. Datum of gage is at mean sea level (levels by Lake Irrigation

District).

Records available.- April 1926 to September 1943.

Extremes^ Maximum contents observed during year, 19,300 acre-feet July 22 (elevation, 

t>,iio.4B feet); no storage during fall and winter.

1926-43: Maximum contents observed, 19,740 acre-feet June 19, 1941 (elevation, 

5,118.75 feet); pr*obably no storage above elevation 5,101.0 feet during tali and winter 

each.

Remarks.- Reservoir Is formed by earth-and rock-fill dam completed In 1926. Capacity, 

16,940 acre-feet between elevations 5,101.0 feet (lower y.mit of capacity table, 4.0 

feet above gate sill of outlet) and 5,117.0 feet (top of flashboards, 5.0 feet above 

spillway crest). Dead storage unknown. Water is ueed for irrigation of about 6,800 

acres of land in vicinity of Norwood. Figures given herein represent contents above 

5,101.0 feet. There is some usable storage below elevation 5,101.0 feet, but natural 

flow passing through reservoir when outlet gates are operating prevents withdrawal of 

storage to elevation of sill of gates. Qage read once daily. Time of reading variable. 

Storage figures from gage heights as observed.

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