SURFACE WATER SUPPLY OF SNAKE RIVER BASIN, 1937

SCOPE OF WORK

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

flow made on streams in the United States during the water year ending September 30, 1937. 

The work was begun in 1888 in connection with special studies relating to irrigation. 

Measurements of stream flow have been made at about 7,200 points in the United States 

and also at many points in Alaska and the Hawaiian Islands. In July 1937, 3,380 

gaging stations were being maintained by the Geological Survey and the 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 acknowedged 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 a 

rate of flow of 1 cubic foot per second, or the rate of discharge of water flowing in a 

channel when the cross-sectional area is 1 square foot and tlie 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 required to cover an 

acre to the depth of 1 foot. The term is commonly used in connection with storage for 

irrigation.

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

24 hours.

"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 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 

measurements in determining the daily flow. The records of stage are obtained either
2 ACCURACY OF FIELD DATA AND COMPUTED RESULTS

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 o'utllned in standard textbooks on the measurement of river 

discharge. Typical gaging stations, equipped with water-stage recorder and 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 daily gage height to these rating tables gives the 

daily discharge from which the monthly and yearly mean discharge is 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 shifting-control method or by use of slope 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. Information under "Extremes" gives 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, 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 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 stations equipped with water-stage recorders the table gives the 

discharge corresponding to the mean daily gage height except for stations on stream subject to sudden or rapid fluctuation. For stations subject to such fluctuation the mean 

daily gage height may not indicate the true mean daily 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 daily discharge from a continuous gage-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 discharge 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 daily 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 under "Remarks" in regard to the general 

accuracy of the records. "Excellent" indicates that, in general, the daily records are

In error not more than 5 percent; "good", not more than 10 percent; "fair", not more than 

15 percent; and "poor", over 15 percent.

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 noncontrlbutlng 

districts In the measured drainage area, by lack of Information concerning 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 probable. The computations are also omitted for stations on streams draining areas In which the annual 

rainfall 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 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 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.

The foregoing table gives, by years and drainage basins, the numbers of the papers on 

surface water supply published from 1899 to 1937. 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 from 1910 to 1920 for any station in the area covered 

by part 3 are published in Water-Supply Papers 283, 303, 323, 353, 383, 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 in the same relative order as the regular gaging stations. An index 

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

From time to time reports have been published that are compilations of records for 

various areas, usually a single State or drainage basin. These reports contain records 

previously published (some of which have been revised), as well as some records not contained in the annual series of water-supply papers. The following table gives the 

numbers and titles of these reports, arranged in alphabetical order by States and 

drainage basins.

Diversions from Snake River between 

Helse and Shelley gaging stations, Idaho

Between Heise and Shelley gaging stations 50 canals divert water from Snake River 

for irrigation; 40 divert above mouth of Henrys Fork and 10 below. Most or these canals 

are equipped with staff gages read once daily; a few have water-stage recorders. Records 

showing combined discharge of all canals for each irrigation season during 1919 to 1937 

are available.

80 TRIBUTARIES BETWEEN PORTNEUF RIVER AND SALMDN FALLS CREEK

Rock Creek near Twin Falls, Idaho

Location.- Water-stage recorder, lat. 42°36', long. 114°32», in SW 1/4 sec. 36, T. 9 S., 

R. 16 E., at highway bridge, 3 miles above mouth and 4- miles northwest of Twin Falls. 

Prior to Sept. 27, 1937 at site 100 feet upstream, datum 1.50 feet higher.

Records available.- March 1922 to September 1937. 

Average discharge.- 15 years, 214 second-feet.

Extremes.- Maximum discharge during year, 514 second-feet Apr. 29 (gage height, 2.36 

reet); minimum, 102 second-feet Apr. 8 (gage height, 0.48 foot).

1922-37: Maximum discharge, 984 second-feet Sept. 21, 1927 (gage height, 4.5 feet, 

from high-water marks); minimum, 94 second-feet Mar. 22, Apr. 1-3, 11, 12, 1935.

Remarks.- Records good except those for two of the periods of missing gage heights, 

Jan. 9-28, Jan. 31 to Feb. 14, which were estimated and are poor. Those for the 

other periods of missing gage heights were computed as follows: For Mar. 14, 15, 

17-22, on basis of gage-height trend Mar. 13, 16, 23; for Apr. 9-11, on basis of 

gage-height record Apr. 8, 12 and records for Twin Falls South Side Canal. Normal 

summer flow practically all diverted for irrigation several miles upstream. Waste 

water from South Side Twin Falls Low Line Canal, which crosses Rock Creek 12 miles 

(revised) above, causes abrupt fluctuations in stage at times. Irrigation wastes 

and drain discharges from project lands enter above gage. Gage-height record furnished by Murtaugh Irrigation District.

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

BOISE RIVER BASIN 123

Drains crossing Phyllls Canal to Boise River, Idaho

Phyllls Canal diverts from 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 Nampa and thence 

westward, passing though sec. 24, T. 3 N., R. 3 W., about 1J miles north of upper 

embankment of Deer Flat Reservoir. Eight principal drains cross Phyllls Canal In this 

reach. Records of the flow of these drains at points from which the flow could be 

diverted, by gravity or pumping, Into Phyllis Canal were collected during the winter 

season, Nov. 20, 1936, to Mar. 31, 1937.

A summary of the drain flow available for diversion during winters 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 drains to supplement the stor^ 

age Impounded In Deer Flat Reservoir.

7 E., 300 feet above mouth of Wilson CreeK, a quarter of a mile below Deadwood Dam at 

lower end of Deadwood Basin, 15 miles north of Lowman, and 18 miles above mouth of Deadwood River.

Drainage area.- 108 square miles.

Records available.- October 1926 to September 1937.

Average discharge.- 10 years, 174 second-feet.

Extremes.- Maximum discharge during year, 1,070 second-feet Aug. 87 (gage height, 4.20 

fept;; practically no flow Dec. 20 to Jan. 12, Mar. 20-31.

1927-37: 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 In dam were 

closed.

Remarks.- Records good except those for periods when reservoir gates were closed, Dec. 20 

to Jan. 12, Mar. 20 to July 10, which are poor. Discharge for Nov. 28, Dec. 19, Jan. 

13, Mar. 19, July 11, Sept. 30, computed on basis of reported gate changes. Flow regulated since Nov. 2, 1930, by operation of gates in Deadwood Dam. During the late fall of 

1936, the U. S. Bureau of Reclamation cut an Intermountaln canal to divert a small flow 

of water from a tributary of Johnson Creek to Deadwood River basin for supplemental 

storage in Deadwood Reservoir. Measurements of July 14 and 25 indicated flow in diversion of 4.82 and 1.76 second-feet, respectively. Once dally staff gage readings Nov. 4 

to Mar. 19 and gage-height record for Oct. 1 to Nov. 3 and July 11 to Sept. 30, furnished by U. S. Bureau of Reclamation.

140 PAYETTE RIVER BASIN

 Payette Lake at Lardo, Idaho

Location.- Staff gage, lat. 44°55' , long. 116°07', In sec. 8, T. 18 N., R. 3 E., at outlet of lake at Lardo. Zero of gage is 4,982.24 feet above mean sea level.

Drainage area.- 131 square miles.

Records available.- August 1921 to September 1937 (fragmentary).

Extremes.- Maximum stage observed during year, 8.08 feet June 19; minimum, 1.25 feet

1921-37: Maximum stage observed, 8.75 feet July 13, 1935; minimum, 0.95 foot Oct. 

3, 1931.

Remarks.- No diversions above station. Regulation of storage for use in lower Payette 

River Valley effected by flashboards on dam in outlet channel. Because of location of 

gage in outlet channel, gage heights show slightly lower elevations at times than those 

that prevailed on main lake. Gage-height record furnished by U. S. Forest Service, 

supplemented by reports from Bureau of Reclamation, July 6 to Aug. 14.
