SURFACE WATER SUPPLY OF SNAKE RIVKR BASIN, 1938

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 tin water year 

ending September 30, 1938. The work was begun in 1888 in connection with special studies 

relating to irrigation. Measurements of stream flow have been made at about 7,800 points 

in the United States and also at many points in Alaska and the Hawaiian Island?. In July 

1938, 3,830 gaging stations were bing maintained by the Geological Survey and cooperating 

organizations. Many miscellaneous discharge measurements were made at 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. Acknowledgments for cooperation of the first kind are made in connection with the description of each station 

affected; cooperation of the second kind is acknowledged on page 8.

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 water flowing in a channel when the cross-sectional area is 1 square 

foot and the 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 

flowing 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", equivalent to 43,560 cubic feet, is the quantity of water required to 

cover an acre to the depth of 1 foot. 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 is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallons and 

represents a run-off of 0.0372 inches from one square mile.

"Stage-discharge relation" is an abbreviation for the term "relation of gag0 height to 

discharge."

"Control" is a term used to designate the natural section or reach of the channel Or 

artificial structure below the gage which determines the stage-discharge relation at the

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 gage heights and discharge

2 EXPLANATION OF DATA

measurements In determining the dally 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 the fluctuations. Measurements of discharge are made w'.tli a current 

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

discharge. Typical gaging stations, equipped with water-stage recorder arti measuring 

cable and car, are shown on plate 1.

Rating tables giving the discharge for any stage are prepared from the discharge 

measurements. The application of the dally gage height to these rating tables gives the 

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

The data presented for each gaging station In the area covered by this report usually 

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 except for those stations whose dally 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 determined from the best available maps, and information in regard to diversions that 

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

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

the number of years Indicated. It is given only for stations for which ttere are 10 or 

more complete years of record. Information under "Extremes" gives the maximum discharge 

and gage height; the minimum discharge if there is little or no regulatior; the minimum 

daily discharge if there Is extensive regulation, and also the minimum discharge If useful; and the minimum gage height except when 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 nonrecording gage read at the time of the crest. Likewise the 

minimum represents the lowest discharge, unless otherwise qualified. The peak discharge 

for the year with the time of Its occurrence Is given below the table of monthly discharge 

for some stations. Selected lower peaks are also given If the peak dlschrrge exceeded the 

mean discharge for that day by more than 10 percent. This supplementary information Is 

generally not given for stations having drainage areas of less than 10 square miles or 

more than 10,000 square miles.

The table of dally discharge gives, for stations equipped with nonrecording gages, the 

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

of the gage. For flashy floods the mean daily discharge Is determined frcm gage-height 

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 the tpble gives the 

discharge corresponding to the mean dally gage height except for stations on streams subject to sudden or rapid fluctuation. For stations subject to such flucturtion the mean 

dally gage height may not indicate the true mean dally discharge, which mrst be obtained 

by averaging the discharge for Intervals of the day or by using the discharge Integrator, 

an instrument for obtaining the mean dally discharge from a continuous gape-height graph 

and containing as an essential element the rating curve of the station.

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

for each month of the figures for that month given in the table of daily discharge. The 

column headed "Maximum11 gives the maximum dally discharge and not the discharge when the 

water surface was at crest height. Likewise, In the column headed "Mlnlnna" the quantity

given Is the minimum dally discharge. The column headed "Mean" Is the average flow In 

cubic feet per second during the month.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily (1) on the permanency of the stagedischarge relation and (2) on the accuracy of observation 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 

percent or more.

The monthly means for any station may represent with high accuracy the quantity of 

water flowing past the gage, but the figures showing discharge per square mile and depth 

in inches may be subject to gross errors caused by the inclusion of large noncontributing 

districts In the measured drainage area, by lack of information concernirg water diverted 

for irrigation or other use, or by inability to interpret the effect of artificial regulation of the flow of the river above the station. "Second-feet per square mile" and 

"run-off In inches" are therefore not computed if such errors appear probrble. The computations are also omitted for stations on streams draining areas in whicl: the annual 

rainfall Is less than 20 inches.

Many gaging stations on streams in the Irrigated areas of the United Statea are situated above most of the diversions from those streams, so that 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 gives a general Idea of the flow at the station. The 

table of daily discharge allows more detailed studies of the variation in flow. It should 

be borne In mind, however, that the observations In each succeeding year may be expected 

to throw new light on data previously published, and that greater degrees of refinement in 

computations and records may be warranted with increased data and use of improved 

equipment.

26 SNAKE RIVER MAIN STEM

Snake River near Hagerman, Idaho

Location.- Water-stage recorder, lat. 42°46', long. 114°53', in NWi sec. 1, T. 8 S., R. 

13 E., just upstream from Upper Salmon Falls, an eighth of a mile upstream from Owsley 

Bridge, and 4 miles south of Hagerman. Big Wood River enters 11 miles downstream. 

Zero of gage is 3,873.46 feet above mean sea level.

Records available.- August 1912 to June 1917, July 1919 to September 1938. 

Average discharge.- 22 years (1912-15, 1919-38), 8,150 second-feet.

Extremes.- Maximum daily discharge during year, 22,300 second-feet May 6; Hnximum gage 

height, 7.37 feet July 2; minimum daily discharge, 5,000 second-feet May 16-18; 

minimum gage height, 3.62 feet May 29.

1912-17, 1919-38: Maximum discharge, 35,100 second-feet June 10, 1914; maximum 

gage height, 9.12 feet June 7, 1936: minimum discharge, 4,030 second-feet July 15 to 

Aug. 2, 1915 (gage height, 3.1 feet). Data in 1916 and 1917 insufficient for determination of maximum and minimum discharge.

Remarks.- Records good. Because of changes in gates and flashboards at Upper Salmon 

Falls, discharge for Nov. 10, Apr. 4-11, Apr. 17 to May 9, and May 11 to July 12 were 

computed on basis of records for Snake River below Lower Salmon Falls. Practically 

entire flow at Milner diverted during irrigation season; only minor diversions below 

Milner.

Discharge, In second-feet, water year October 1937 to September 1936

T. UN., R. 45 E., 2 miles upstream from Alpowa Creek, 7 miles below Clarkston, and 

134 miles upstream from mouth. Zero of gage Is 670 feet above mean sea level (benchmark of Corps of Engineers, U. S. Army).

Drainage area.- 103,200 square miles.

Records available.- Ocotber 1915 to September 1922 and August 1928 to September 1935 

(at site at Riparia, 66 miles downstream) and October 1935 to September 1938 in reports of Geological Survey. October 1909 to September 1933 (at former site) In State 

Water-Supply Bulletin 5. All records equivalent.

Average discharge.- 29 years (1909-38), 46.,320 second-feet.

Extremes.- Maximum discharge during year, 219,-000 second-feet May 29, 30 (gage height, 

32.44 feet); minimum, 14,100 second-feet Oct. 1 (gage height, 9.54 feet).

1909-38: Maximum discharge observed, 270,000 second-feet May 20, 1921 (gage 

height, 19.0 feet, at former site); maximum gage height known, 24.7 feet, at former 

site, June 5, 1894 (discharge, about 409,000 second-feet); minimum discharge, possibly as low as 9,000 second-feet sometime during period of ice effect, Jan. 6 to 

Feb. 20, 1937.

Remarks.- Records excellent except those for period of missing gage heights, Dec. 7-14, 

which were computed on basis of recorded range of stage, and records for Clear-water 

River at Spalding, Idaho, and are fair. Small diversions by pumping between this 

station and the one at Oxbow.i Considerable diurnal fluctuation as a result of 

pondage for power on Clearwater River at Lewiston.

66 BIG LOST RIVER BASIN

Mackay Reservoir near Mackay, Idaho

Location.- Staff gage on head-gate tower of dam, lat. 43°57', long. 113°40', in sec. 12, 

T. 7 N., R. 23 E., 4 miles northwest of Mackay. Zero of gage is 6,000 above mean sea 

level.

Records available.- January 1919 to September 1938.

Extremes.- Maximum contents during year, 41,270 acre-feet May 30 (gage height, 64.20 

feet); minimum, 142 acre-feet Oct. 3-8 (gage height, 7.85 feet).

1919-38: Maximum contents, those of May 30, 1938; no available storage during some 

periods in 1919, 1920, 1924, 1926, 1929, and each year of period 1931-1935; minimum 

stage, 6.3 feet Aug. 5, 1934.

Remarks.- Gage heights computed as for midnight on day shown based on once-daily gage 

readings Oct. 1 to Apr. 30 and Aug. 22 to Sept. 30, and twice-daily gage readings 

May 1 to Aug. 21. Capacity of reservoir is 33,400 acre-feet between gage heights 7.0 

and 62.0 feet. Water is used for irrigation of lands within Big Lost River irrigation district. There is considerable seepage around the dam because of its porous 

foundation, but the greater part of this water finds its way back to Big Lost River 

between the reservoir and station below the reservoir near Mackay. Gage-height 

record and capacity table furnished by water-master for Big Lost River.

BIG WOOD RIVER BASIN 

Big Wood River above North Gooding canal, near Shoshone, Idaho

93

Location.- Staff gage, lat. 43°06', long. 114°18', in sec. 10, T. 4 S., R. 18 E., 1 mile 

upstream from North Gooding canal, 13 miles below Magic Dam, and 14 miles northeast of 

Shoshone.

Records available.- April 1921 to September 1938.

Extremes.- Maximum discharge during year, 4,560 second-feet about Apr. 22 (gage height, 

9.63 feet, from high-water marks); no flow Oct. 1 to Apr. 19 and July 21 to Sept. 30. 

1921-38: Maximum discharge, that for Apr. 22, 1938; no flow for long periods.

Reiaarks.- Records good except those for period of missing gage heights, July 18-20, which 

were computed on basis of field estimates of flow and are poor. Discharge for Apr. 

23-27 computed on basis of records for station below Magic Dam. Many diversions for 

irrigation. Richfield and Lincoln canals are main diversions between station and 

Magic Dam. Lincoln canal, completed in spring of 1925, diverts all the flow, except 

during high water, around station on right bank to avoid channel losses in the natural 

stream bed. Flow regulated by diversions above station and by operation of head gates 

at Magic Dam. Gage-height record and two discharge measurements furnished by watermaster for Big Wood and Little Wood Rivers.

Extremes.- Maximum discharge during year, 12,800 second-feet May 3 (ga?e height, 9.12 

feet); minimum, 31 second-feet Aug. 10 (gage height, 0.26 foot).

1920-38: Maximum discharge observed, 14,500 second-feet May 19, 20, 1921; maximum 

gage height, that of May 3, 1938; minimum discharge, 10 second-feet Aug. 18, 1920.

Remarks,.- Records good except those for period of missing gage heights. Oct. 4-31, which 

were estimated and are poor, and those for periods of channel changs, Jan. 26 to 

May 1, which were computed on basis of five discharge measurements, recorder records, 

and records for nearby stations and are fair. Discharge for Oct. 1-3 computed on 

basis of once-daily staff-gage readings at former site, 360 yards downstream. Station is below all diversions for irrigation in Boise Valley. Flow regulated by storage in Arrowrock Reservoir. Many diversions for irrigation above station.

140 BOISE RIVER BASIN

Drains crossing Phyllls canal to Boise River, Idaho

Phyllls canal diverts from the left bank of Boise River In sec. 24, T. 4 N., R. 1 W., 

3£ miles southwest of Eagle. The canal flows west and south through Namja and thence 

westward, passing through sec. 24, T. 3 N., R. 3 W., about 1J miles nortt of upper embankment of Deer Flat Reservoir. Eight principal drains cross Phyllls canal in this reach. 

Records or the flow of these drains at points from which the flow could te diverted by 

gravity or pumping Into Phyllls canal were collected during the winter season, November 

£3, 1937, to March 31, 1938.

A summary of the drain flow available for diversion during winter searons is useful In 

conjunction with records for North and South Channels of Boise River near Eagle, to determine the feasibility of diverting water from these sources to supplement the storage 

Impounded In Deer Flat Reservoir.

north side of Malheur River. In 1930 capacity of reservoir was increased by 

flashboards from 170,000 acre-feet at gage height 74.0 feet (crest of spillway) to 

192,500 acre-feet at gage height 79.0 feet (top of flashboards).

Extremes.- Maximum discharge observed during year, 1,320 second-feet Jun* 10 (gage

 height, 4.65 feet); minimum, not determined, occurred when gates at dam were closed. 

1927-38: Maximum discharge. 2,150 second-feet May 26, 1928 (gage height, 5.67

feet, at former site and datum); practically no flow for long periods when gates Indam were closed. 

Remarks.- Records good except those for periods when reservoir gates wer^ closed, Oct.

 1, Dec. 12 to Feb. 16, Feb. 21 to June 4, which are poor. Discharge for Oct. 2, 3,

gate changes, and that for June 4 computed on basis of reported flow over spillway. 

Flow regulated since Nov. 2, 1930, by operation of gates In Deadwood Dam. During 

the late fall of 1936, the Bureau of Reclamation cut an intermountain canal to divert 

a small flow from a tributary of Johnson Creek to Deadwood River Basin for supplemental storage in Deadwood Reservoir. Measurement of July 17 Indicated a flow In diversion of 9.08 second-feet. Once-daily staff-gage readings Oct. 2 to Di?c. 11, Feb. 17- 

20, June 5-21 and gage-height record for June 22 to Sept. 30 furnished by Bureau of

Records available.- October 1929 to September 1938. November 1910 to Augrst 1912 (gage 

heights only) at approximately same site.

Extremes.- Maximum discharge during year, 24,500 second-feet April 18 (gage height, 11.07 

feet); minimum, 267 second-feet Dec. 8 (gage height, 1.23 feet).

1929-38: Maximum discharge, 34,800 second-feet June 10, 1933 (gage height, 13.44 

feet), from rating curve extended above 25,000 second-feet; minimum, probably less 

than 100 second-feet Jan. 8, 1937, during period of ice effect.

Remarks.- Records good. No diversions.

Revislo"n.- Figure of yearly mean discharge and that of discharge per square mile for
