SURFACE WATER SUPPLY OF SNAKE RIVER BASIN, 1942

SCOPE OF WORK

This volume is one of a series of 14 reports presenting results of measurements of 

stage and flow nade on streams, lakes, and reservoirs in the Uhitsd States during the 

water year ending September 30, 1942. 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 contents of lakes and reservoirs have been made at about 9,400 gaging stations 

in the United States and also at many gaging stations in Alaska and Hawaii. In July 1942, 

4,970 gaging stations were being maintained by the Geological Survey and cooperating 

organizations. Miscellaneous discharge measurements were made at many other points.

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

either by furnishing data or by assisting 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 on page 11.

DEFINITION OF TERMS

The units in which stream-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 

whose average velocity is 1 foot per second.

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

second from each square mile of area drained, on the assumption that the run-off is distributed uniformly both as regards time and area.

"Run-off 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. It is used 

for comparing run-off 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 commcnly used in connection with 

storage for irrigation.

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

hours. It is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallons and 

represents a run-off of 0.0372 inch from 1 square mile.

"Stage-discharge relation" Is an abbreviation for the term "relation between gage 

height and discharge."

"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.

EXPLANATION OF DATA

The base data collected at gaging stations consist of records of stage, measuremsnts 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 on plate 1.

Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application of the dally mean gage height to these 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 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 "shifting-control" 

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 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 stations In the same or nearby basins. The days 

Included in the periods of ice effect and the days during the winter period on which discharge measurements were made are Indicated In the table of 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 daily discharge of 

the stream, and a table of monthly and yearly discharge and run-off. Skeleton rating 

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

preater 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 

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 i^ecords. Under "Average discharge" is given the 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 daily 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 times of their occurrence are given below the table of monthly discharge for some 

stations. This supplementary information' is generally omitted for stations having drainage areas of less than 10 square miles or more than 10,000 square miles or if the peak 

discharges usually exceed the corresponding mean discharges for the day by less than 10 

percent.

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 flashy floods the daily mean discharge Is determined from gageheight graphs based on gage readings made once or twice daily or oftener, as stated in 

the station description. 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 

dally 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.

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 dally discharge and not the momentary discharge when the 

water surface was at crest stage. Likewise, in the column headed "Minimum" the quantity 

given is the minimum daily 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 stage 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.

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. This made February 9 a 23-hour day. Time prior to 2 a.m.
4 SURFACE WATER SUPPLY, 1942, PART 13

February 9 as given herein refers to standard time; time after 2 a.m. February 9 refers 

to war time. To convert war time to standard time, subtract 1 hour.

Records of daily discharge prior to February 9, 1942, published herein have been computed on the basis of standard time. Records subsequent to that date have been computed 

on the basis of war time. The discharge given for February 9 is the mean for 23 hours. 

The mean discharge and run-off for the month of February have been computed from the total 

second-foot-days for the month without adjustment for the fact that February 9 was a 

23-hour day. The small error resulting from this procedure has been disregarded.

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 dally records are accurate within 

5 percent; "good," within 10 percent; "fair," within 15 percent; and "poor," within 20 or 

a higher percent. The records of monthly and yearly mean discharge and run-off 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 "secondfeet per ,s qua re mile" and "run-off in inches" are not published unless 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. Figures of second-feet per square mile and run-off 

in inches are also omitted if the drainage area includes large noncontrlbutlng 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 affords opportunity for more detailed stuTlies 

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 7. 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 Tapers 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 each year and are published under "Miscellaneous discharge measurements" at the 

end of each report, the streams and points of measurement listed appearing In the sane 

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. 7), contains a summary 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.

Note.- Of the records for the stations operated by the Oregon State engineer, those for 1925-30 are 

published In Bulletin 8 of the State engineer, and those fop 1931-36 (Including some to December 

1936) In Bulletin 9; those for 1937-42 have not been published.

Records for the stations operated by Idaho Water District 36 are published In the annual reports of 

that organization.

The Soil Conservation Service began In 1938 to make studies of run-off from two areas of less than 

220 acres each In the vicinity of Enmett, Idaho, and from two areas of less than 180 acres each In 

the vicinity of Moscow, Idaho. The records are In the files of that organization.

w., at dam on Snake River,at Moran. Datum of gage Is at mean eea level (levels by 

Bureau of Reclamation).

Drainage area.- 816 square miles.

Records available.- July 1908 to September 1942 (1908-10, fragmentary).

Extremes.- Maximum contents during year 853,380 acre-feet July 1 (elevation, 6,769.26 

reet;; minimum, 227,740 acre-feet Oct. 1 (elevation, 6,742.26 feet).

feet); no usable contents, on 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. 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-feet. The earth 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 gatee). 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.

Location.- Water-stage recorder, lat. 43°18', long. 116°26', In NEi sec. 35, T. 1 S.,

K. 11*., 4i miles downstream from Swan Falls power plant and 7i miles northeast of

Murphy.

Drainage area.- 41,900 square miles.

Hecords avaiiaDle.- August to October 1912, August 1913 to September 1942. 

Average aiscnargeT- 29 years (1913-42), 10,550 second-feet. 

Ejqremes.- naxiiHum discharge during year, 23,900 second-feet Apr. 27 (gage height, 8.92

reetJT minimum, 6,760 second-feet (regulated) Aug. 12 (gage height, 3.75 feet).

1912-42: Maximum discharge, 47,300 second-feet June 22, 1918 (gage height, 13.95

feet, site and datum then In use); minimum observed^ 3,950 second-feet (discharge

measurement) July 20, 1934, when stage was below Intake pipe. 

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

good. Diurnal fluctuations caused by gates and power plant at dam. Several diversions

by pumping between this station and station at King Hill. 

Correction.- The minimum dally discharge for the water year 1941 has been corrected to

e,9BO second-feet, superseding figure published In Water-supply Paper 933.

Island Park Reservoir near Island Park, Idaho

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 1942.

Extremes.- Maximum contents observed during year, 137,230 acre-feet May 29 (elevation

 6,203.25 feet); minimum observed, 39,140 acre-feet Oct. 3, 4 (elevation, 6,285.55 feet).

1938-42: Maximum contents observed, that of May 29, 1942; 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) and 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. 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.

42 HENRYS FORK BASIN

Diversions from Henrys Fork between Ashton and St. Anthony gaging stations, Idaho

Between Ashton and St. Anthony gaging stations seven canals divert water from Henrys 

Fork for Irrigation. Records available for each irrigation season from 1919 to 1942. 

Discharge of canals computed from staff-gage readings, or interpolated, and combined to 

show total diverted flow. Records good for July 17 to Sept. 30, when all staff gages 

were read dally, and fair for May 1 to July 16, when some gages were read dally and some 

biweekly.

Discharge, In second-feet, water year October 1941 to September 1942

for Irrigation. Records available for part of each irrigation season from 1919 to 1942. 

Discharge of canals computed from staff-gage readings, or Interpolated, and combined to 

show total diverted flow. Records good for July 1 to Sept. 30, when all staff gages 

were read daily, and fair for Hay 1 to June 30, when some gages were read daily and some 

biweekly.

feet); practically no storage Oct. 1 to Nov. 15, 1937 (at 4 p.m., Nov. 15 water was 

diverted from Camas Creek into lake).

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

water and surface tributaries. For complete description of Mud Lake region see Watersupply Paper 818. Water for irrigation is diverted from lake and tributaries by pumping and gravity. Camas Creek diversion canal reported in operation Oct. 1-31 and 

July 20 to Sept. 30. Area of lake is varied from time to time by changes In dikes. 

High winds occasionally disturb the recording of lake stages. Figures given herein 

represent contents above gage height, -4.0 feet. Capacity table prepared from surveys 

made by Geological Survey adjusted for changes in dikes.

wnicn are fair. Diversions above station for irrigation. The sum of the combined discharge of east and west channels of Big Lost River and of the combined discharge of 

east and west channels of Warm Spring Creek, near Mackay, represents practically entire 

surface flow of Big Lost River whidh enters Mackay Reservoir.

Cooperation.- Gage-height record furnished by wateimaster for Big Lost River.

17.

1917-42: Maximum contents observed, 300,900 acre-feet May 4, 5, 1939 (elevation, 

3,219.0 feet); no storage during period in each of several years when natural flow 

was passing through reservoir.

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, which, project officials state, 

may have been reduced as much as 5,000 to 6,000 acre-feet by the deposition of silt.

1926-42: Maximum 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 1933-42 when gates In dam were closed.

Remarks.- Records good except those below 5 second-feet &nd those for Sept. 2-28, which

 are fair. Flow regulated since Nov. 2, 1930, by Deadwood Reservoir (see preceding 

page). During late fall of 1936 the Bureau of Reclamation cut transmountaln canal to 

divert a small flow from a tributary of Johnson Creek to Deadwood River Basin for 

supplemental storage in Deadwood Reservoir. Discharge measurements made on. May 28, 

July 1, and field estimate on Sept. 2, 1942, Indicate flow In this canal of 20.3,

152 PAYETTE RIVER BASIN

Payette Lake at Lardo, Idaho

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

~or iaKe on North Fork of Payette River, at Lardo. 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 1942 (fragmentary).

Extremes.- Maximum gage height observed during year, 8.12 feet July 2, 3;-minimum observed, 

1.79 feet Oct. 4.

1921-42: Maximum 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 range by a structure consisting of a serlee 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 a 

variation in stage of 5 feet corresponds to a capacity of about 25,000 acre-feet. 

Water Is used for Irrigation of lands in vicinity of Qnmett. No diversion above 

station. Because of draw-down In outlet channel, stages at gage are slightly lower at 

times than stages of lake.

Cooperation.- Gage-height record furnished by Forest Service supplemented during period 

nay 19 to July 31 by observation by employee of Payette valley Water Users Association 

and July 19 to Sept. 2 by records of Bureau of Reclamation.

PAYETTE RIVER BASIN 157

Lake Fork Reservoir near McCall, Idaho

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

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

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

Records available.- April 1926 to September 1942.

Extremes.- Maximum contents observed during year, 19,010 acre-feet July 5 (elevation, 

5,118.30 feet); no storage during fall and winter.

1926-42: Maximum contents observed, 19,740 acre-feet June 19, 1941 (elevation, 

5,118.75 feet); probably no storage above elevation 5,101.0 feet during fall and 

winter each year .

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

 16,5)40 acre-feet between elevations 5,101.0 feet (lower limit 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 used for irrigation of 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. Gage read once daily.

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

Extremes.- Maximum discharge during year, 59,900 second-feet May 27 (gage height, 27.00 

feet); minimum, 3,360 second-feet Feb. 19 (gage height, 11.99 feet).

1910-17, 1919-42: Maximum discharge observed, 88,800 second-feet June 9, 1921 

(gage height, 31.2 feet), from rating curve extended above 75,000 second-feet; minimum discharge, 1,580 second-feet Dec. 11, 1932 (gage height, 10.23 feet), from rating 

curve extended below 2,200 second-feet.
