SURFACE WATER SUPPLY OF SNAKE RIVER BASIN, 1940

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, 1940. 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 8,800 gaging stations In the United States 

and also aft many gaging stations In Alaska and Hawaii. In July 1940, 4,760 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 10.

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 commonly used In connection with 

storage for irrigation.

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

hours. It Is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 6^6,317 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 a feature below the gage that defines the stagedischarge 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 stag-e, measurements of 

discharge, and general information used to supplement the records of stsge 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. 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 mean daily gage height to these rating tables gives the 

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

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

comprise a description of the station, a table showing the daily discharge of ths 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 rega~d 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 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 nonrecording gage read at the time of the crest. Likewise the minimum discharge represents the lowest stage, 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 exceedsd 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 nonrecording 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 daily 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 txiose on 

streams subject to sudden or rapid fluctuation, the table gives the discharge co^responding to the mean daily gage height. 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.

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 

or fall in a reach of the stream as a factor in the determination of discharge. Information requisite for determining the slope or fall is obtained by means of an auxiliary

GAGING-STATION STRUCTURES.
EXPLANATION OF DATA 3

gage set at some distance from the base gage. The auxiliary gage, If one is used, is 

described under "Location." 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 occasional winter discharge 

measurements and gage heights, 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 disc^iarge measurements were made are indicated in the table by symbols referring to footnotes.

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 "Maximum" gives the maximum daily discharge and not the instantaneous 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.

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 daily records are accurate within 

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

a higher percent.

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 "run-off in inches" are not published unless storage or diversion records 

are included indicating the extent of the regulation or diversion or unle°s 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 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 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 the Increase In data and the use of 

Improved equipment.

Note.- Reports containing records for years after 1901 are given ir table on page 6.

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

the papers on surface water supply published from 1899 to 1940. The data Tor 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, 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.- Of the records for the stations operated by the Oregon State engineer, those fo" 1925-50 

are published In Bulletin 8 of the State engineer, and those for 1951-56 (Including some to 

December 1936) In Bulletin 9; those for 1937-40 have not been published.

Records for the stations operated by Idaho Water District 56 are published in the annual reports 

of that organization.

The Soil Conservation Service began In 1958 to make studies of run-off from two areas of less 

than 250 acres each In the vicinity of Emmett. Idaho, and from two areas of less than 10T acres each 

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

COOPERATION

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

IP. GAGING-STATION RECORDS

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., a 

short distance above dam on Snake River. Datum of gage is at mean sea level (levels 

by Bureau of Reclamation.)

Drainage area.- 816 square miles.

Records available.- July 1908 to September 1940 (1908-10, fragmentary).

Extremes.- Maximum contents during year, 853,640 acre-feet June 15 (elevation, 6,769.26 

feet); minimum, 154,790 acre-feet Sept. 19 (elevation, 6,738.57 feet).

1908-40: Maximum contents, 857,220 acre-feet June 23, 1937 (elevation, 6,769.40 

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

6,730.00 feet).

Re-narks.- Reservoir was formed in 1906 by log crib dam, with a uspMe capacity of 300,000 

acre-feet. This dam was washed out in July 1910 and replaced 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 gates) above 

 nean sea level. Water is used for irrigation in Snake River Valley, Idaho. Gage 

read once daily at 7 a.m. during irrigation season and at 8 a.m. during res': of year. 

Contents as given are computed from elevation at those times; all available for release.

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

Geological Survey
SNAKE RIVER MAIN STEM 15

Snake River near Heise, Idaho

Location.- Water-stage recorder, lat. '43°37', long. 111°40', in sec. 5, T. 3 N., R. 41 E., 

3 miles upstream from Heise and 23 miles upstream from Henrys Fork. Datum of gage is 

5,014.90 feet above mean sea level.

Drainage area.- 5,740 square miles.

Records available.- September 1910 to September 1940 except for winters of 1914-24.

Average discharge.- 30 years (1910-40), 6,770 second-feet.

Extremes.- Maximum discharge during year, 13,900 second-feet June 17 (gage height, 5.87 

feet); minimum, 1,740 second-feet Jan. 20 (gage height, 1.60 feet).

1910-40: Maximum discharge, about 60,000 second-feet May 19, 1927, result of washing 

out of landslide on Gros Ventre River (gage height, about 16.0 feet, present datum); 

minimum, 1,210 second-feet Jan. 22, 1935 (gage height, 1.15 feet).

Remarks.- Records excellent except those for periods of ice effect, which are fair. Station is above all irrigation diversions from main river except Riley ditch (capacity, 

about 30 second-feet), which diverts 1 mile above station. About 105,000 acres irrigated 

by diversions from tributaries above station in both Wyoming and Idaho. Flow partly 

regulated by Jackson Lake (see p. 12 ).

Diversions from Snake River between Heise and Shelley gaging stations, Idaho

Between Heise and Shelley gaging stations, 47 canals divert water from Snake River for 

Irrigation; of these, 36 divert above mouth of Henrys Fork. Records available diring each 

Irrigation season from 1919 to 1940. One of the canals is equipped with a water-stage 

recorder, the others with staff gages which are read once daily; records of discharge are 

combined to show total diverted flow. Records good except those for May, which are fair.

 published (10,100 square miles) did not include area of Mud Lake Basin.

Records available.- March 1915 to September 1940 ( summer months only during some years ) .

Extremes.- Maximum discharge during year, 9,470 second-feet June 7 (gage height, 7.91

 feet ) : minimum, 1,010 second-feet Sept. 19 (gage height, 4.18 feet).

1915-40: Maximum discharge, 47,200 second-feet June 17, 1918 (cage height, 16.97 

feet); minimum, 288 second-feet Nov. 5, 1934 (gage height, 2.22 feet).

Greatest discharge known, slightly In excess of 70,000 second-feet (estimated) June

Diversions from Snake River between Shelley and Clough Ranch gaging stations, Idaho

Between Shelley and Clough Ranch, 13 canals divert water from Snake River for irrigation. Records available during each irrigation season from 1919 to 1940. The two largest 

canals are equipped with recorders, the others with staff gages which are read once dally. 

Records of discharge are combined to show total diverted flow, and are good.

Location.- Water-stage recorder, lat. 43°07', long. 112°31', in SEt sec. 30 (revised), T. 

3 S., R. 34 E., a quarter of a mile downstream from Blackfoot River and 14 miles 

southwest of Blackfoot.

Drainage area.- Indeterminate because of large noncontributing areas. Figure previously 

published (11,700 square miles) did not include area of Mud Lake-Lost River Basin.

Records available.- June 1910 to September 1940.

Extremes.- Maximum discharge during year, 6,620 second-feet June 9 (gage height, 5.55 

reetj; minimum, 148 second-feet July 15 (gage height, 0.57 foot).

1910-40: Maximum discharge, 46,200 second-feet June 18, 1918 (gage height, 14.80 

feet); minimum, 111 second-feet Nov. 10, 1934 (gage height, 0.80 foot). Late in summer of 1905 there was no flow in Snake River for a distance of 10 miles In vicinity of 

Blackfoot. On Aug. 9, 1905, discharge of Snake River just below mouth of Blackfoot 

River was 39 second-feet, supplied by ground-water inflow a short distance upstream.

Remarks.- Records excellent. Flow regulated by Jackson Lake (see p. 12), Henrys Lake 

(see p. 40), Island Park Reservoir (see p. 44), Grassy Lake (see p. 6T), and BlackfootMarsh Reservoir, having a combined capacity of 1,483,000 acre-feet. Many diversions 

above station for irrigation.

Remarks.- Records good. Flow regulated by American Falls Reservoir (see p. 20), Lake 

Walcott (see p. 23) and other reservoirs having a combined usable capacity of about 

3,300,000 acre-feet, and greatly reduced by diversions at Milner Dam fo~ irrigation. 

About 1,300,000 acres of land irrigated by diversions from river and its tributaries 

above station. Flow includes some stored water released for use below station by 

Idaho Power Co.

(at former site) in State Water-Supply Bulletin 5.

Average discharge.- 31 years (1909-40), 47,700 second-feet.

Extremes.- Maximum discharge during year, 126,000 second-feet May 12, 13 (gage height, 24.7 

feet); minimum, 11,500 second-feet Aug. 25; minimum gage height, 8.68 feet Aug. 17.

1909-40: Maximum discharge observed, 270,000 second-feet May 20, 1921 (gage height, 

19.0 feet, site and datum then In use); minimum discharge, possibly as low as 9,000 

second-feet sometime during period of ice effect, Jan. 6 to Feb. 20, 1937.

Maximum stage known, 24.7 feet, at Riparia, June 5, 1894, from floodmarks, determined by U. S. Weather Bureau (discharge, 409,000 second-feet).

Remarks.- Records excellent. Small diversions by pumping between this station and station 

at Oxbow. Large diurnal fluctuation caused by power plant on Clearwater River above 

Lewiston.

Island Park Reservoir near Island Park, Idaho

Location.- Staff gage on reservoir bank and mercury pressure gage in gate house, lat. 

44"£b', long. 111°24', 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 1940.

Extremes.- Maximum contents observed during year, 135,855 acre-feet Apr. 29 (elevation 

6,303.08 feet); minimum observed, 16,855 acre-feet Sept. 27 (elevation 6,274.22 feet).

1938-40: Maximum contents observed, 136,905 acre-feet May 5-6, 1939; minimum 

observed, that of Sept. 27, 1940.

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) above mean sea level. 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 once daily at 8 a.m. Contents given herein are computed from elevation at that 

time; all available for release.

Cooperation.- Gage-height record and capacity table furnished by Bureau of Reclamation.

(gage height, 3.1 feet, datum then In use from floodmark), from rating curve extended 

above 100 second-feet; minimum observed, that of Jan. 15, 1940.

Remarks.- Records good. Hany diversions above and below station for irrigation. Prior to 

1937 water was stored In small reservoir of Blalne County Investment Co. on Dry Creek, 

about 40 miles above station, and during irrigation seasons was released and carried 

through Corral and Wet Creeks to Little Lost River, from which It was diverted into the 

company's main canal a quarter of a mile bel-ow station.

Geological Survey
76 BIG LOST RIVER BASIN

Big Lost River (east channel) above Mackay Reservoir, near Mackay, 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 1940. 

Average discharge.- 21 years, 49.0 second-feet.

Extremes.- Maximum discharge during year, 465 second-feet June 1 (gage height, 3.40 feet); 

practically no flow Mar. 1 to May 12, Aug. 23-30.

1919-40: Maximum discharge, 1,320 second-feet June 7, 1938 (gage height, 5.02 

feet); no flow during long periods in each year of 1920, 1923-38, 1940.

Remarks.- Records good except those for periods of no gage-height record, 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 entire surface flow of Big Lost 

River which enters Mackay Reservoir.

Cooperation.- Gage-height record and estimates of flow Aug. 31, 

by water-master for Big Lost River.

from confluence with Marsh Creek.

Records available.- September 1937 to September 1940. October 1911 to August 1914, at 

site about l-t miles upstream.

Extremes.- Maximum discharge observed during year, 13 second-feet May 12-15; maximum gage 

height observed, 1.05 feet May 13, 14; minimum discharge observed, 5.6 second-feet Mar. 

5; minimum gage height observed, 0.74 foot Kar. 18.

1911-14, 1937-40: Maximum discharge observed, 95 second-feet July 15, 1938, by 

velocity-area method on basis of floodmark at measuring section; minimum observed, 3.4 

second-feet Dec. 24-27, 1913.

Remarks.- Records good. Gage read twice daily. Malad power plant, which has a small

reservoir above station, may cause slight diurnal fluctuations. Water is diverted from 

Eirch Creek half a mile belov, station and carried by internountain canal to Devil Creek

Geological Survey
94 TRIBUTARIES BETWEEN PORTNEUF RIVER AND. SALMON FALLS CREEK

Goodlng canal at Mllner, Idaho

Location.- Water-stage recorder on Mllner-Gooding canal In SWi sec. 7 and staff gages

 on North Side Canal Co. diversions In sees. 18 and 19, T. 10 S., R. 21 E., about 3 

miles downstream from head gates that are In sec. 2S, T. 10 S., R. 21 E., lat. 42 31 , 

long. 114°01'.

Records available.- May 1930 to September 1940.

Extremes.- Maximum dally discharge during year, 2,410 second-feet July 15-21; no flow at 

times. 1939-40: Maximum dally discharge, that of July 15-21, 1940; no flow at times.

Remarks.- Records good. Goodlng canal diverts water from Snake River for Mllner-Gooding

 project of Bureau of Reclamation and In part for project of North Side Canal Co. The 

latter project also receives water through the North Side Twin Falls canal and P. A. 

lateral. Discharge of canal computed by combining the discharge of Mllne--Goodlng 

diversion and that of North Side Canal Co. diversions below their division point and 

adding 20 to 50 second-feet to that sum for loss between head gates and division 

point.

Cooperation.- Gage-height record and some discharge measurements furnished by North Side 

Canal Co. and American Falls Reservoir District No. 2.

Discharge, In second-feet, water year October 1939 to September 1940

96 TRIBUTARIES BETWEEN PORTNEUF RIVER AND SALMON FALLS CREEK

South Side Twin Falls canal at Milner, Idaho

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

ti., 700 feet downstream from head gates at Milner.

Records available.- May 1909 to September 1940.

Extremes.- Maximum discharge during year, 3,640 second-feet July 21 (gage height, 10.42

 feet); minimum, 35 second-feet (estimated) Oct. ,29 to Nov. 2.

1909-40: Maximum daily discharge, 4,600 second-feet Aug. 12, 1918, computed on 

basis of stage-discharge relation for canal plus estimates by hydrograpl: er of water 

wasted through spillway; no flow Sept. 20, 1920.

Remarks.- Records excellent except those for periods of ice effect, which are good, and

 those of no gage-height record, which are fair. Flow controlled by operation of head 

gates. South Side Twin Falls 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 furnished by Twin Falls Canal Co.

Discharge, in second-feet, water year October 1939 to September 1940

TRIBUTARIES BETWEEN PORTNEUF RIVER AND SALMON FALLS CREEK 

Rock Creek near Twin Falls, Idaho

97

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

 16 K., at highway bridge, 3 miles upstream from mouth and 4 miles northwest of Twin 

Falls.

Records available.- March 1922 to September 1940. 

Average discharge.- 18 years, 211 second-feet.

Extremes.- Maximum discharge during year, 460 second-feet Aug. 30 (gage height, 3.16

 feet); minimum, 95 second-feet Mar. 29, 30 (gage height, 1.74 feet).

1922-40: Maximum discharge, about 984 second-feet Sept. 21, 1927 (ga,?e height, 4.5 

feet, datum then in use, from floodmarks); minimum, 94 second-feet Mar. 22, Apr. 1-3, 

11, 12, 1935.

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 Fells low-line canal, which crosses Roc'-c Creek 12 

miles upstream from station, causes abrupt fluctuations In stage at times. Irrigation 

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

108 BIG WOOD RIVER BASIN 

Big Wood Slough at Halley, Idaho

Location.- Water-stage recorder, lat. 43°31'00", long. 114°19'30", in sec. 9, T. 2 N., R. 

18 E., at highway bridge, an eighth of a mile northeast of steel highway bridge over 

Big Wood River, and an eighth of a mile southwest of Halley.

Records available.- June 1915 to September 1940. 

Average discharge.- 25 years, 111 second-feet.

Extremes.- Maximum discharge recorded during year, 272 second-feet July 6 (gage height, 

3.34 feet); minimum, 1 second-foot Mar. 30 to Apr. 23, May 1-3, 8.

1915-40: Maximum discharge observed, 419 second-feet June 6, 1921, fron rating 

curve extended above 280 second-feet; maximum gage height, 5.55 feet (elevation of 

top of ice In well) Jan. 20-23, 1937; no flow May 8, 1931, Oct. 20 to Nov. 3, 1938.

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

Flow affected by operation of Halley power plant half a mile upstream. Big Wood 

Slough, a natural channel of Big Wood River, is utilized as a tallrace for the power 

plant, and its discharge plus the discharge of Big Wood River at Halley, Idaho, gives 

the total flow of river at this point.

Cooperation.- Gage-height record and two discharge measurements furnished by water-master 

for Big Wood and Little Wood Rivers.

Discharge, in seccnd-feet, water year October 1939 to September 1940

 E., a quarter of a mile upstream from outlet of canal, 7 miles west of Richfield, 11 

miles northeast of Shoshone, and 12i miles downstream from Magic Dam.

Records available.- May 1925 to September 1940 (1929-36, irrigation season only).

Extremes.- Maximum discharge during year, 162 second-feet May 23 (gage height, 1.14 feet); 

no flow for long periods.

1925-40: Maximum discharge, 667 second-feet May 29, 1927 (gage height, 2.48 feet), 

from rating curve extended above 550 second-feet; no flow for long periods each year.

Remarks.- Records good. Canal diverts water from right bank of Big Wood River in sec. 9,

 T. 3 S., R. 18 E., from which point it approximately paralells rtver for 10 miles, to 

head of North Gooding canal, in sec. 15, T. 4 S., R. 18 E., where its water is either 

diverted into North Gooding canal or returned to Big Wood River. Canal is used to 

avoid large channel losses in natural bed of river. Five ditches have rights to divert 12.5 second-feet above this station for irrigation.

Cooperation.- Gage-height record and three discharge measurements furnished by watermaster

 lor Big Wood and Little Wood Rivers.

UNITED STATES DEPART-TO1 OF THE INTERIOR 

Geologic Survey
BOISE RIVER BASIN 

Arrowrock Reservoir at Arrowrock, Idaho

133

Location.- Graduations on upstream face of dam on Boise River, lat. 43°36', long. 115°55', 

in Et 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 1940.

Extremes.- Maximum contents observed during year, 299,700 acre-feet June 1 (elevation, 

3,218.6 feet}; minimum observed, 11,260 acre-feet Nov. 1 (elevation, 3,035.0 feet). 

1917-40: Maximum contents, 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 crncrete-arch dan, 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) above mean sea level. 

Dead storage negligible. Figures given herein represent total contents. Project 

officials state that total capacity of reservoir may have been reduced as raich as 5,000 

or 6,000 acre-feet by the deposition of silt. Water is used for irrigation of lands 

in Boise Valley.

Cooperation.- Gage-height record and capacity table furnished by Bureau of Reclamation.

Contents, In acre-feet, water year October 1939 to September 1940

MALHEUR RIVER BASIN 159

Reservoirs in Malheur River Basin, Oreg.

VJarmsprings Reservoir.- Tape gage, lat. 43°35', long. 118°12', in SEi sec. 8, T. 23 S., R.' 

37 E., at dam on Malheur River, 4 miles upstream from South Fork of Malheur River and 4 

miles northwest of Riverside. Datum of gage is 3,327 feet above mean sea level (surveys 

of Bureau of Reclamation); gage readings have been reduced to elevations above mean sea 

level. Drainage area, 1,100 square miles. Records available, January 1920 to September 

1940. Maximum contents observed during year, 193,800 acre-feet Apr. 22 (elevation, 

3,406.82 feet); minimum observed, 65,460 acre-feet Oct. 5-10, 27, 28 (elevation, 

3,371.85 feet). Maximum contents observed during period 1920-40, that of Apr. 22, 1940; 

no storage Sept. 18 to Nov. 1, 1929, Aug. 26 to sometime in November 1935.

Revision.- Beginning October 1939, capacity table used has been slightly revised on 

basis of data furnished by Bureau of Reclamation. Previously published contents of 

194,300 acre-feet for elevation of 3,406.40 feet on May 19-22, 1938, reduced to 191,800 

acre-feet by revised table.

Reservoir is formed by concrete arch dan; storage began in 1919. Capacity, 190,000 

acre-feet (revised) between elevations 3,327 feet (bottom of outlet tunnel) and 3,406 

feet (top of 5-foot flashboards). Dead storage, 1,400 acre-feet below elevation 3,327 

feet. Figures given herein represent usable capacity. In 1926 a half interest in reservoir was purchased by the Federal Government for Vale project of Bureau of Reclamation. Gage readings furnished by Bureau of Reclamation. Water used to irrigate lands 

on both sides of river between Namorf and Ontario.

Agency Valley Reservoir.- Pressure gage with mercury column, lat. 43°55', long. 118°09', in 

SW:i sec. 15, T. 19 S., R. 37 E., at dam on North Fork of Malheur River, a quarter of a 

mile northwest of Beulah. Gage readings are elevations above mean sea level by original surveys of Bureau of Reclamation, or 7.72 feet less than elevations above mean sea 

level by 1929 general adjustment. Drainage area, 420 square miles. Records available, 

December 1935, when storage began, to September 1940. Maximum contents observed during 

year, 61,060 acre-feet Mar. 27 (elevation, 3,340.60 feet); minimum obse--ved, 29,410 

acre-feet Sept. 18 (elevation, 3,320.9 feet). Maximum contents observed during period 

1935-40, that of Mar. 27, 1940; minimum observed since full capacity was attained on 

Apr. 9, 1938, that of Sept. 18, 1940.

Reservoir is formed by earthfill rock-faced dam; storage began in 1935. Capacity, 

59,920 acre-feet between elevations 3,263.21 feet (bottom of outlet tunnel) and 3,340 

feet (top of 17-foot spillway gates); with gates lowered the capacity is 32,220 acrefeet. No dead storage. Figures given herein represent usable contents. Water is 

used for irrigation of lands below Juntura, on Vale project of Bureau of Reclamation. 

Capacity table and dally gage readings furnished by Bureau of Reclamation.

Other reservoirs.- There are several other reservoirs in the Malheur River Basin, all with 

less than 3,500 acre-feet capacity except Williw Creek Ho. 3 Reservoir near Malheur, 

which has a capacity of 49,000 acre-feet.

PAYETTE RIVER BASIN 167

Deadwood Reservoir near Lowman, Idaho

Location.- Staff gage at dam on Deadwood River, lat. 44°18', long. 115°39', in SE± sec. 

8, T. ]1 N., R. 7 E., 15 miles north of Lowman. Datum of gage is at irean sea level 

(levels by Bureau of Reclamation).

Drainage area.- 108 square miles.

Records available.- October 1935 to September 1940.

Extremes.- Maximum elevation observed during year, 5,335.6 feet June 4-8; minimum observed, 

 5,291.9 feet Oct. 4, 5, 9, 10, 12-14.

1936-40: Maximum elevation observed, 5,336.6 feet June 9, 10, 193f; minimum observed, 5,260.1 feet Oct. 1, 1935.

Remarks.- Reservoir Is formed by concrete arch darn, completed In 1930; storage began Nov. 

ii, 19SO. Reported capacity 160,400 acre-feet between elevation 5,230.0 feet (minimum 

operating level because of fish protection, 27 feet above sill of emergency gate in 

front of needle valve) and 5,334.0 feet (crest of spillway). Storage below elevation 

5,230.0 feet about 1,500 acre-feet. Water Is used to augment flow of Payette River at 

Black Canyon power plant near Emmett. During the late fall of 1936, Bureau of Reclamation cut an intermountain canal to divert a small flow of water fron a tributary of 

Johnson Creek In Salmon River Basin to Deadwood River Basin for supplemental storage 

In Deadwood Reservoir. Measurement of June 14, 1940, Indicates a flov in this canal 

of 30.6 second-feet. Gage read once dally.

Cooperation.- Gage-height record furnished by Bureau of Reclamation.

Geological Survey
1AJ PAYETTE RIVER BASIN

Payette Lake at Lardo, Idaho

Location.- Staff gage at outlet or lake on North Fork of Payette River, lat. 4<J-°55', long.

 JL16°07', In sec. 8, T. 18 N., R. 3 E., at Lardo. Datum 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 1940 (fragmentary).

Extremes.- Maximum gage height observed during year, 8.14 feet June 15; minlmuti observed, 

1.57 feet Nov. 10, 17, 21.

1921-40: 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 the natural range by a structure 

consisting of a series of concrete filled cribs supporting removable flasMnards, 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 Emmett. No diversion above station. 

Because of drawdown In outlet channel, stages at the gage are slightly lower at times 

than stages of lake.

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

 period July 5 to Aug. 16 by records of Bureau of Reclamation.

Gage height, in feet, water year October 1939 to September 1940
