SURFACE WATER SUPPLY OF SNAKE RIVER BASIN, 1939

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, 1939. The work was begun in 1888 in connection with special studies 

relating to Irrigation. Measurements of flow of streams and measurements of stage and contents or lakes and reservoirs have been made at about 8,240 gaging stations In the United 

States and also at many gaging stations in Alaska and Hawaii. In July 1939, 4,160 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 cooperat-Jd, 

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 9.

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 Tor "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 or 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-root," 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-root 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 one square mile.

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

discharge."

"Control" Is a term used to designate the natural section or reach or the channel or 

artiricial structure below the gage that 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 with a current 

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

discharge. Gaging station structures are shown on plate 1.

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

mean 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 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 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 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 minlmun daily 

discharge if there is extensive regulation (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 discharge 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 daily discharge gives, for stations equipped with nonrecordlnj gages, the 

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

of twice-daily readings. For flashy floods the mean dally discharge is determined from 

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, except 

those on streams subject to sudden or rapid fluctuation, the table gives the discharge 

corresponding to the mean daily gage height. For stations subject to such fluctuation the 

mean daily gage height may not indicate the true mean dally discharge, which must 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 gageheight 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" giv^s the sum 

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

column headed "Maximum" gives the maximum daily discharge and not the discharge when the 

water surface was at crest height. 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.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily on (1) the permanency of the stagedischarge relation and (2) 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 per cent; "fair," within 15 percent; and "poor," within 20 or a 

higher percent.

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

owing to diversions, amount consumed, 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 "run-off In Inches" are not published unless reservoir 

records are included Indicating the extent of the regulation, or 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, 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 dally discharge allows more detailed studies of the variation In flew. 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 the increase In data and the use of Improved 

equipment.

Note.- The reports that contain records for years after 1901 are given in the table on 

Page 6.

The table on the following page gives, by years and drainage basins, the numbers of 

the papers on surface water supply published from 1899 to 1939. 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 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 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.

 Records for some earlier years published in water-supply papers of the Geological Survey.

Note.- All the stations in the above table were operated by the State engineer of 

Oregon, and the records have been published in the bulletins of that office, as follows: 

Those for 1915-24, In Bulletin 7: those for 1925-30, in Bulletin S, those for 1931-36 

(including some to December 1936), In Bulletin 9. Records for 1937-39 have not been 

published.

Records of run-off have also been collected by the Soil Conservation Sen-ice from two 

areas of less than 250 acres each near Emmett, Idaho, and two areas of less than 100 acres 

each near Moscow, Idaho. These records an contained in the files of the Soil Conservation 

Service.

COOPERATION

The work In the several States was done under cooperative agreements witl the organizations listed below.

Idaho: Department of Reclamation, R. W. Faris, succeeded Jan. 1, 1P39, by James 

Spofford, commissioner, and the State Water Conservation Board, N. V. fharp, chairman. 

Oregon: Office of the State engineer, Charles E. Strlcklin.

Washington: State Department of Conservation and Development, John Brooke Fink, 

director, and C. J. Bartholet, supervisor of hydraulics.

Wyoming: Office of the State engineer, John B. Quinn, succeeded by L. C. Bishop. 

Financial assistance was also furnished by the Corps of Engineers, United States Army; 

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

the Interior; the Flood Control Committee, the Weather Bureau, the Soil Conrervatlon Service, and the Forest Service, United States Department of Agriculture; and tte Works 

Progress Administration.

Funds for the construction, repair, and improvement of gaging stations wrcre allocated 

to the Geological Survey by the Federal Emergency Administration of Public Works.

Assistance in collecting records was rendered also by the following municipalities, 

organizations, corporations, and individuals:

and Weiser Rivers and Mud Lake.

Oregon: Warmsprings Irrigation District, Malheur, Baker, Union, and Wallowa Counties, 

Eastern Oregon Light & Power Co., and Inland Power & Light Co.

DIVISION OF WORK

The data for Snake River at and above Milner, Idaho, for stations on tributaries that 

enter Snake River above Idaho Falls (except those in the Salt River Basin in Wyoming), and 

for Blackfoot River near Blackfoot, Idaho, were collected and prepared for publication under 

the supervision of Lynn Crandall, district engineer. For all other stations in Idaho, for 

stations in Salmon Falls Creek. Basin in Nevada, and for Snake River at Oxbow, Oreg., the 

data were collected and prepared for publication under the supervision of T. R. Newell, 

district engineer.

For all other stations in the several states the data were collected and p-epared for 

publication under the supervision of district engineers as follows: In Oregoi, G. H. 

Canfield, the work being done in collaboration with Charles E. Stricklin, State engineer; 

in Washington, G. L. Parker; in Wyoming, Robert Follansbee; and in Nevada, A. B. Purton.
GAGING STATION RECORDS 11

SNAKE RIVER MAIN STEM 

Jackson Lake at Moran, Wyo.

Location.- Staff gage, lat. 43°51', long. 110"35' In sec. 18, T. 45 N., R. 114 W., on 

Bnake River, a short distance above lake outlet at Moran. Zero of gage Is 6,700 feet 

above mean sea level (Bureau of Reclamation datum).

Drainage area.- 816 square miles.

Records available.- July 1908 to September 1939 (1908-10, fragmentary).

Extremes.- Maximum contents during year, 850,300 acre-feet June 19 (gage height, 69.13 

feet); minimum, 312,530 acre-feet Sept. 29 (gage height, 46.32 ft.).

1908-39: Maximum contents, 857,220 acre-feet, June 33, 1937 (gage height, 69.40 

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

30.00 feet).

Remarks.- In 1906 Bureau of Reclamation began construction of a log crib dam, which created a reservoir with a usable capacity of 300,000 acre-feet. This dan washed but In 

July 1910 and was replaced by an earth dam, creating a capacity of 380,000 acre-feet. 

The earth dam was raised In 1916 and the capacity thereby Increaspd to about 790,000 

acre-feet. In 1917, by dredging the outlet, the capacity was further Increased to 

847,000 acre-feet between gage heights 30 and 69 feet (gate sill Is at gage height 28 

feet). Water Is used for Irrigation In Snake River Valley, Idaho. Gage read once 

dally, at 7 a.m., and contents as given computed from gage height at that time; all 

available for release. Gage-height record furnished by Bureau of Reclamation.

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

Wood River.

Records available.- May 1909 to September 1939. 

Average discharge.- 30 years, 10,740 second-feet.

Extremes.- Maximum discharge during year, 17,800 second-feet Apr. 11 (gage height, 9.34 

reet;; minimum, 6,060 second-feet June 1 (gage height, 5.32 feet).

1909-39: Maximum discharge, 47,200 second-feet June 22, 1918 (gage height, 16.3 

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

Remarks.- Records excellent. Discharge for periods of missing gage heights, Sept. 11-16, 

18-24, computed on basis of records for stations below Lower Salmon Falls (near Hagerman) 

and near Murphy; that for Sept. 17 computed on basis of once-daily staff-gage reading. 

Practically entire flow at Milner diverted during Irrigation season, so ttat flow at 

King Hill Is derived largely from springs and from seepage entering below Milner.

BIG LOST RIVER BASIN 85

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

Location.- Water-stage recorder, lat. 43°59', long. 113°45', in sec. 32, T. 8 N., R. 23 

E., 3 miles upstream from Mackay Dam, above flow line of reservoir, and about 7i miles 

northwest of Mackay.

Records available.- May 1919 to September 1939. 

Average discharge.- 20 years, 49.3 second-feet.

Extremes.- Maximum discharge during year, 265 second-feet May 51 (gage height, 2.78 feet),

 computed by slope method; minimum, 3 second-feet Aug. 14 (gage height, 0.13 foot). 

1919-39: Maximum discharge, 1,320 second-feet June 7, 1938 (gage height, 5.02 

feet); no flow during long periods In 1920 a .d each year of 1923-38.

Remarks.- Records fair January to September; others good. Discharge for period when

 stage-discharge relation was affected by backwater from Mackay Reservoir, Jan. 1 to 

June C, computed on basis of discharge measurements, slope methods, weather records, 

and records for stations on nearby streams. 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 Paver, which enters Kackay 

Reservoir.' Gage-height record and results of three discharge measurements furnished 

by watermaster for Big Lost River.

Warm Spring Creek (east channel) near Mackay, Idaho

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

23 K., 700 feet upstream from confluence with west channel of Warm Spring Creek and 

about 74 miles northwest of Mackay. Prior to Dec. 3, 1938, staff gage at site 200 feet 

downstream, datum 0.29 foot lower.

Records available.- May 1919 to September 1939. 

Average discharge.- 20 years, 28.5 second-feet.

Extremes.- Maximum discharge recorded during year, 37 second-feet my 19, 20 (gage height, 

1.90 feet); minimum, 13 second-feet Apr. 27-29, Aug. 23, 24; minimum gage height, 1.49 

feet Apr. 28, 29.

1919-39: Maximum discharge, 225 second-feet June 15, 1922; minimum,9 second-feet 

May 8, 9, 13, 14, 1919, and May 18-21, 1920.

Remarks.- Records good except those for Oct. 1 to Dec. 2 and May 21 to June 30, which are 

 fair. Discharge May 28-30 computed on basis of records for stations on nearby streams. 

Practically all natural flow diverted during Irrigation season. Flow during summer 

represents return water from Irrigation. The sum of the combined discharge of east 

and west channels of Warm Spring Creek and the combined discharge of east and west 

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

of Big Lost River, which enters Mackay Reservoir. Gage-height record and results of 

two discharge measurements furnished by watermaster for Big Lost River.

 Stage-discharge relation affected by ice; discharge computed on basis of two discharge measurements, gage heights, weather records, and records for Arrowrock Reservoir at Arrrnroek and South 

Fork of Boise River near Lenox.
146 BOISE RIVER BASIN

Arrowrock Reservoir at Arrowrock, Idaho

Location.- Graduations on face of dam on Boise River, lat. 43°36', long. 115°5a', in Ei

 sec. 13, T. 3 N., R. 4 E., at Arrowrock, 22 miles by road east of Boise. Zero of gage 

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

Drainage area.- 2,210 square miles.

Records available.- October 1917 to September 1939.

Extremes.- Maximum contents during year, 300,900 acre-feet May 4, 5 (gage height, 3,219.0

 feet); minimum, 15,620 acre-feet Sept. 30 (gage height, 3,047.0 feet).

1917-39: Maximum contents, those of May 4, 5, 1939; no storage during p3riod 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 

elevation 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. Project officials state that total 

capacity of reservoir may have been reduced as much as 5,000 to 6,000 acre-feet by the 

deposition of silt. Water is used for irrigation of lands in Boise Valley. Gageheight record and capacity table furnished by Bureau of Reclamation.

PAYETTE RIVER BASIN 187

Payette Lake at Lardo, Idaho

Location.- Staff gage at outlet of lake on North Fork of Payette River, lat. 44°55', 

long. 116 007', in sec. 8, T. 18 IJ., R. 3 E., at Lardo. Zero of gage is 4,982.24 feet 

above mean sea level (general adjustment of 1912).

Drainage area.- 131 square miles.

Records available.- August 1921 to September 1939 (fragmentary).

Extremes.- Maximum rage height observed during year, 8.40 feet June 17; minimum observed, 

1.52 feet Sept. 29.

1921-39: 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 ttie natural range by a structure 

consisting 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 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 the vicinity of Qmett. No diversion above 

station. Because of drawdown in outlet channel stages at the gage are slightly lower 

at times than stages of lake. Gage-height record furnished by U. S. Forest Service 

supplemented during period May 31 to Aug. 8 by records of Bureau of Reclamation.

YEARLY-DISCHARGE SUMMARY 

PART 13. SNAKE RIVER BASIH

The following tables summarize in convenient form for general reference and for use in 

preliminary investigations the figures of yearly discharge and run-off for certain gaging 

stations in the Snake River Basin, previously published in the annual series of watersupply papers. All gaging stations, both active and discontinued, at which 10 or more 

complete years of record have been collected and published are represented, also some 

special stations, as noted below. The summaries present figures of maximum and minimum 

daily discharge and yearly mean discharge and run-off, for both the water years ending 

September 30 and the calendar years. The figures for the water years prior to 1911 and 

figures for the calendar years 1911 to 1933 have not been previously published in the 

annual water-supply papers but are included in these summaries.

The number of the water-supply paper in which the figures of daily and monthly discharge as well as yearly discharge are published is shown in the column headed W.S.P. (no. 

and page). The descriptions contained in the water-supply papers indicated give detailed 

information relative to the gaging stations, including location, diversions, regulation by 

storage, effect of irrigation, and other pertinent information. Records for stations 

which were operated prior to 1901 are generally contained in the annual reports of the 

Geological Survey. Reference is made to these reports if records have not also been published in water-supply papers.

Figures of drainage area are given for each station when known. These figures have 

been revised from time to tirne as more accurate maps have become available. The discharge 

per square mile and run-off in inches in the following tables, in general, have been revised according to the latest figure for the drainage area.

Summaries for incomplete years are given for those stations in irrigated regions for 

which seasonal records were collected in order to show the flow available for irrigation. 

They have been compiled from the records of daily and monthly discharge contained in the 

water-supply paper indicated. For summaries after 1911 if the period extends beyond 

Sept. 30, records of daily and monthly discharge after that day are contained in the 

water-supply paper indicated for the following year. An incomplete year is included for 

other stations if the maximum daily discharge or minimum daily discharge for all the years 

of record occurred in that year.

Former names under which records for some of the stations have been published in the 

annual water-supply papers are indicated in these yearly summaries as follows:

1. If the name of the stream or town or other feature to which the station Is 

referred has been changed, the former name is given in parentheses, indicating that records for some of the earlier years are published under the obsolete name.

2. If the entire name of a station has been changed, the superseded name and years 

when it was used are given in parentheses beneath the present name.
