AUTHORIZATION AND SCOPE OF WORK

This volume is one of a series of 14 reports presenting records of 

measurements of flow made on streams in the United States during 

the year ending September 30, 1925.

The data presented in these reports were collected by the United 

 States Geological Survey under the following authority contained 

in the organic law (20 Stat. L., p. 394):

Provided, That this officer [the Director] shall have the direction of the Geological Survey and the classification of public lands and examination of the 

geological structure, mineral resources, and products of the national domain.

The work was begun in 1888 in connection with special studies 

relating to irrigation in the West. Since the fiscal year ending 

June 30, 1895, successive appropriation bills passed by Congress have 

carried the following items:

For gaging the streams and determining the water supply of the United States, 

and for the investigation of underground currents and artesian wells, and for the 

preparation of reports upon the best methods of utilizing the water resources.

In the execution of the work many private and State 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 10.

Measurements of stream flow have been made at about 5,120 

points in the United States and also at many points in Alaska and 

the Hawaiian Islands. In July, 1925, 1,710 gaging stations were 

being maintained by the Survey and the cooperating organizations. 

Many miscellaneous discharge measurements were made at other 

points. In connection with this work data were also collected in 

regard to precipitation, evaporation, storage reservoirs, river profiles,

1
J SURFACE WATER SUPPLY, 1925, PART XII B

and water power in many sections of the country and will be made 

available in water-supply papers from time to time.

DEFINITION OF TERMS

The volume of water flowing in a stream the "run-off" or "discharge" is expressed in various terms, each of which has become 

associated with a certain class of work. These terms may be divided 

into two groups (1) those that represent a rate of flow, as seeondfeet, gallons per minute, miner's inches, and discharge in second-feet 

per square mile, and (2) those that represent the actual quantity of 

water as run-off in inches, acre-feet, and millions of cubic feet. The 

principal terms used in this series of reports are second-feet, secondfeet per square mile, run-off in inches, and acre-feet. They may be 

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 of 

rectangular cross section 1 foot wide and 1 foot deep at an average 

velocity of 1 foot per second. It is generally used as a fundamental 

unit from which others are computed.

"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 the 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.

The following terms not in common use are here defined:

"Stage-discharge relation," an abbreviation for the term "relation 

of gage height to discharge."

"Control," a term used to designate the section or sections of the 

stream channel below the gage which determine the stage-discharge 

relation at the gage. It should be noted that the control may not 

be the same section or sections at all stages.

The "point of zero flow" for a gaging station is that point on the 

gage the gage height at which water ceases to flow over the control.

EXPLANATION OF DATA

The data presented in this report cover the year beginning October 

1, 1924, and ending September 30, 1925. At the beginning of January in most parts of the United States much of the precipitation
EXPLANATION OP DATA O

in the preceding three months is stored as ground water, in the form 

of snow or ice, or in ponds, lakes, and swamps, and this stored water 

passes off in the streams during the spring break-up. At the end of 

September, on the other hand, the only stored water available for 

run-off is possibly a small quantity in the ground; therefore the runoff for the year beginning October 1 is practically all derived from 

precipitation within that year.

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 from

FIGUKE 1. Typical gaging station

direct readings on a staff or chain gage or from a water-stage recorder 

that gives a continuous record of the fluctuations. Measurements of 

discharge are made with a current meter. The general methods are 

outlined in standard textbooks on the measurement of river discharge. 

A typical gaging station equipped with water-stage recorder and 

measuring cable and car is shown in Figure 1.

From the discharge measurements rating tables are prepared that 

give the discharge for any stage. The application of the daily gage 

heights 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 comprise a description of the station, a table giving 

records of discharge measurements, a table showing the daily discharge of the stream, and a table of monthly and yearly discharge 

and run-off.
4 SURFACE-WATER SUPPLY, 1925, PART XII B

If the base data are insufficient to determine the daily discharge, 

tables giving daily gage height and records of discharge measurements are published.

The description of the station gives, in addition to statements 

regarding location and equipment, information in regard to any 

condition that may affect the permanence of the stage-discharge 

relation, covering such subjects as the occurrence of ice, the use of 

the stream for log driving, shifting of control, and the cause and 

effect of backwater; it gives also information as to diversions that 

decrease the flow at the gage, artificial regulation, maximum and 

minimum recorded stages, and the accuracy of the records.

The table of daily discharge gives, in general, the discharge in 

second-feet corresponding to the mean of the gage heights read each 

day. At stations on streams subject to sudden or rapid diurnal 

fluctuations the discharge obtained from the rating table and the 

mean daily gage height may not be the true mean discharge for the 

day. If such stations are equipped with water-stage recorders, the 

mean daily discharge may be obtained by averaging discharge at 

regular intervals during the day or by using the discharge integrator, 

an instrument operating on the principle of the planimeter and containing as an essential element the rating curve of the station.

In the table of monthly discharge the column headed "Maximum" 

gives the mean flow for the day when the mean gage height was 

highest. As the gage height is the mean for the day it does not 

indicate correctly the stage when the water surface was at crest 

height and the corresponding discharge was consequently larger than 

given in the maximum column. Likewise, in the column headed 

"Minimum" the quantity given is the mean flow for the day when the 

mean gage height was lowest. The column headed "Mean" is the 

average flow in cubic feet per second during the month. On this 

average flow computations recorded in the remaining columns, 

which are defined on page 2, are based.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily (1) on the 

permanency of the stage-discharge relation and (2) on the accuracy 

of observation of stage, measurements of flow, and interpretation of 

records.

A paragraph in the description of the station gives information 

regarding the (1) permanence of the stage-discharge relation, (2) 

precision with which the discharge rating curve is defined, (3) refinement of gage readings, (4) frequency of gage readings, and (5) methods 

of applying daily gage height to the rating table to obtain the daily 

discharge.
PUBLICATIONS O

For the rating tables "well defined" indicates, in general, that the 

rating is probably accurate within 5 per cent; "fairly well defined," 

within 10 per cent; "poorly defined," within 15 to 25 per cent. 

These notes are very general and are based on the plotting of the 

individual measurements with reference to the mean rating curve.

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 run-off 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 

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. All figures 

representing "second-feet per square mile" and "run-off in inches" 

published in the earlier reports by the Survey should be used with 

caution because of possible inherent sources of error not known to 

the Survey.

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 stations 

must first be satisfied. To give an idea of the amount of prior appropriations, a paragraph on diversions is presented in each station 

description. The figures given can not be considered exact but 

represent the best information available.

The tables of monthly discharge give only a general idea of the 

flow at the station and should not be used for other than preliminary 

estimates; the tables of daily discharge allow more detailed studies 

of the variation in flow. It should be borne in mind, however, that 

the observations in each succeeding yeaf may be -expected to throw 

new light on data previously published.

PUBLICATIONS

Investigation of water resources by the United States Geological 

Survey has consisted in large part of measurements of the volume 

of flow of streams and studies of the conditions affecting that flow, 

but it has comprised also investigation of such closely allied subjects 

as irrigation, water storage, water powers, underground waters, and 

quality of waters. Most of the results of these investigations have 

been published in the series of water-supply papers, but some have 

appeared in the bulletins, monographs, professional papers, and 

annual reports.

Year

The records at most of the stations discussed in these reports 

extend over a series of years, and miscellaneous measurements at 

many points other than regular gaging stations have been made
8 SURFACE WATER SUPPLY, 1925, PART XII B

each year. An index of the reports containing records obtained 

prior to 1904 has been published in Water-Supply Paper 119.

The table following gives, by years and drainage basins, the numbers of the papers on surface-water supply published from 1899 to 

1918. The data for any particular station will, as a rule, be found in 

the reports covering the-years during which the station was maintained. For example, data for Machias River at Whitneyville, Maine, 

1903 to 1921, are published in Water-Supply Papers 97, 124, 165, 201, 

241, 261, 281, 301, 321, 351, 381, 401, 431, 451, 471, 501, and 521, 

which contain records for the New England streams from 1903 to 

1921. Results of miscellaneous measurements are published by 

drainage basins.

GAGING-STATION RECORDS

SNAKE RIVER

SNAKE RIVER AT SOUTH BOUNDARY OF YELLOWSTOWE NATIONAL PARK

LOCATION. A quarter of a mile below junction of Lewis and Snake Rivers, half 

a mile north of Snake River Park ranger station and south boundary of 

Yellowstone National Park, and 25 miles north of Moran, Wyo.

DRAINAGE AREA. 190 square miles (measured on topographic maps).

RECORDS AVAILABLE. June 19, 1913, to September 30, 1925.

GAGE. Stevens 8-day water-stage recorder on right bank referred to auxiliary 

chain gage on bridge. Overhanging chain gage oh right bank 2J^ miles 

above used only as reference gage. Read by Joseph Markham.

DISCHARGE MEASUREMENTS. Made from cable 225 feet below upper reference 

gage or by wading.

CHANNEL AND CONTROL. Bed composed of coarse gravel; clean except for occasional lodgment of drift. Control probably permanent at ordinary stages. 

One channel at gage but divided by an island into two channels at control. 

Condition at upper auxiliary location similar except that the stream is in one 

channel at all stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during periods ©ctotoer 

1-17 and June 16 to July 15, 7.24 feet at 11 p. m. June 20 (discharge, 6,450 

second-feet); minimum stage, 2.49 feet from 8 to 11 a. m. October 1 (discharge, 229 second-feet); probably even lower stages occurred during period 

of no record.

1913-1925: Maximum discharge recorded in 1925; minimum stage, 1.4 

feet October 26-31, 1915 (discharge, 160 second-feet).

ICE. Stage-discharge relation not affected by ice, the formation of which is 

prevented by hot springs above gage.

DIVERSIONS. None above station.

REGULATION. None.

ACCURACY. Stage-discharge relation practically permanent. Rating curves 

fairly well defined. Operation of water-stage recorder satisfactory. Daily 

discharge obtained by applying mean daily gage height to rating table. 

Records good.

COOPERATION. Gage-height record parti y furnished by .United States Bureau of 

Reclamation.

DIVERSIONS FROM SNAKE RIVER BETWEEN HEISE AND SHELLEY GAGING STATIONS, IDAHO

Between Heise and Shelley gaging stations 50 separate canals divert water 

from Snake River for irrigation. More than one-third of these head in the 

Great Feeder, an old channel of the river, which has been equipped with head 

gates. Gaging stations are maintained at head of each canal by the United 

States Geological Survey for the Idaho State Department of Reclamation to 

facilitate distribution of the water. Records are available from June 1, 1919, 

to September 30, 1925.

Stage-discharge relation on most of the canals is affected by growth of aquatic 

plants or by operation of check gates. Rating ciirves well defined. Gages read 

to hundredths daily June 1 to August 31, on alternate days during month of 

May, and occasional readings during September. Records good.

Combined daily discharge, in second-feet, of canals diverting from Snake River between the Heise and Shelley gaging stations, for the irrigation season of 1925

SNAKE RIVER 21

SNAKE RIVER NEAR SHELLEY, IDAHO

LOCATION. In sec. 17, T. 1 N., R. 37 E., a quarter of a mile above Woodville

highway bridge and 3 miles north of Shelley, Bingham County. 

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 18, 1915, to September 30, 1925. 

GAGE. Water-stage recorder on right bank; inspected by C, A. McCurdy. 

DISCHARGE MEASUREMENTS. Made from cable 600 feet above gage or by wading. 

CHANNEL AND CONTROL. Control formed by lava-rock reef extending across

channel about 500 feet below gage. Banks high and clean at gage and control 

EXTREMES OF DISCHARGE. Maximum stage recorded during period October 1

to November 8 and April 3 to September 30, 12.54 feet at 5 p. m. May 23

(discharge, 27,600 second-feet); minimum stage, 4.16 feet from 1 to 2.30

p. m. October 3 (discharge, 1,020 second-feet).

1915-1925: Maximum stage recorded, 16.97 feet at 1.30 p. m. June 17,

1918 (discharge, 47,200 second-feet); minimum stage, 3.61 feet at 1.30 p. m.

September 19, 1924 (discharge, 666 second-feet). 

ICE. Stage-discharge relation probably seriously affected by ice; observations

discontinued during winter. 

DIVERSIONS. Practically the entire normal summer flow of river above station

is appropriated by numerous diversions in the Idaho Falls district. 

REGULATION. Normal flow during the irrigation season is augmented by release

of stored flood waters in Jackson Lake for use on the Minidoka and Twin

Falls tracts.

ACCURACY. Stage-discharge relation permanent. Rating curve fairly well defined. Operation of water-stage recorder satisfactory except for short periods.

Daily discharge obtained by applying mean daily gage height to rating table.

Records good.

DIVERSIONS FROM SNAKE RIVER BETWEEN SHELLEY AND BIACKFOOT BRIDGE GAGING

STATIONS, IDAHO

Fourteen separate canals divert water from Snake River for irrigation between 

Shelley and Blackfoot Bridge gaging stations. Gaging stations are maintained 

at heading of each canal by the United States Geological Survey for the Idaho 

State Department of Reclamation to facilitate distribution of the water. Records 

are available from May 19, 1924, to September 30, 1925. From June 1, 1919, 

to September 30, 1923, diversions from Snake River were summarized in two 

groups with the station at Porterville Bridge for the intermediate point. After 

October 1, 1923, the intermediate point was at Blackfoot Bridge.

Stage-discharge relation on most of the canals is affected by growth of aquatic 

plants or by operation of check gates. Rating curves are well defined. ' Gages 

read to hundredths on alternate days during May, daily June 1 to August 31, 

and occasionally during September. Records good.

REGULATION. Normal flow during irrigation season is augmented by the release 

of stored .flood waters in Jackson Lake for use on the Minidoka and Twin 

Falls tracts.

ACCURACY. Stage-discharge relation changed for low water during the period 

of record. Rating curves well defined. Operation of water-stage recorder 

satisfactory. Daily discharge ascertained by applying to rating table mean 

daily gage height determined by inspecting recorder graph or as noted in 

footnote to table of daily discharge. Records good.

At this point Snake River is divided into three channels, which are listed from 

east to west as Nos. 1, 2, and 3. One gage serves for Nos. 1 and 2 channels and 

one gage for No. 3 channel.

DIVERSION FROM SNAKE RIVER BETWEEN BLACKFOOT BRIDGE AND ClOUGH RANCH GAGING

STATIONS, IDAHO

Between Blackfoot Bridge and Clough ranch gaging stations, one small canal 

(Smith Maxwell Canal) diverts water from Snake River for irrigation. A 

gaging station is maintained at heading of canal by the United States Geological 

Survey for the Idaho State Department of Reclamation to facilitate distribution 

of the water. Records are available from May 1 to September 30, 1924 and 1925.

Stage-discharge relation is affected by growth of aquatic plants. Rating 

curve fairly well defined. Gage read to hundredths daily May 14 to September 

30. Discharge estimated May 1-13. Records fair.

SNAKE MVEB AT CIO UGH RANCH, NEAR BIACEFOOT. IDAHO '

LOCATION. In sec. 31, T. 3 S., R 34 E., a quarter of a mile below mouth of 

Blackfoot River and 14 miles southwest of Blackfoot, Bingham-County. 

Blackfoot River is the only large tributary between station and mouth of 

Henrys Fork, 60 miles above. Portneuf and Bannock Rivers and about 2,500 

second-feet of spring water enter between this station and station at Neeley.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. June 6, 1910, to September 30, 1925.

GAGE. Friez water-stage recorder on right bank; installed July 6, 1913; inspected 

by J. A. Clough.

DISCHARGE MEASUREMENTS. Made from cable 50 feet above gage or by wading.

CHANNEL AND CONTROL. Bed composed of very coarse gravel. Two channels 

at low and medium stages. Control shifts slightly during high water.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 10.59 feet at 

3 a. m. May 24 (discharge, 24,700 second-feet); minimum stage, 2.12 feet 

at 1 p. m. October 4 (discharge, 442 second-feet).

1910-1925: Maximum stage recorded, 14.8 feet (approximately) at 5 p. m. 

June 18, 1918 (discharge, about 46,200 second-feet); exact discharge uncertain because of probable shift in stage-discharge relation at about this time. 

Minimum stage, 1.93 feet at 6 p. m. August 25, 1919 (discharge, 118 secondfeet!

1 Formerly known as " Snake River near Blackfoot."
SNAKE RIVER 29

ICE, Floating ice sometimes present for short periods; stage-discharge relation 

apparently not affected.

DIVERSIONS. Practically entire normal summer flow of river is diverted above 

station.

REGULATION. Flow regulated by storage in Jackson Lake Reservoir and in 

Blackfoot-Marsh Reservoir on Blackfoot River. Practically entire sjommer 

flow is released water from these reservoirs.

ACCURACY. Stage-discharge relation changed during high water in May. 

Rating curves well defined. Operation of water-stage recorder satisfactory except for short periods in winter when clock stopped and occasional staff gage readings were used. Daily discharge ascertained by applying mean daily gage height to rating table. Shifting-control method used 

May 21-23. Records good.

SNAKE RIVER AT NEEIEY, IDAHO

LOCATION. In seo. 11, T. 8 S., R. 30 E., half a mile north of Neeley post office, 

Power County, 4 miles northwest of American Falls, and 32 miles above 

Minidoka Dam. Portneuf and Bannock Rivers and 2,500 second-feet of 

spring water enter Snake River between this station and station at Clough 

ranch. Raft River enters 18 miles below Neeley.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 17, 1906, to September 30, 1925.

GAGE. Friez water-stage recorder installed August 8, 1910, on left bank at 

same site and datum as staff gage previously used; inspected by A. J. Ayers.

DISCHARGE MEASUREMENTS. Made from cable at gage.

CHANNEL AND CONTROL. Bed of river at measuring section rough, especially 

near right bank. One channel at all stages. Control composed of lava 

rock, probably partly overlain with coarse gravel; shifts slightly.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 10.04 feet at 

11 p. m. May 24 (discharge, 26,800 second-feet); minimum stage, about 2.97 

feet from 11 a. m. to 4 p. m. October 7 while float well was being deepened 

(discharge, about 1,040 second-feet).

1906-1925: Actual maximum stage doubtful; maximum mean daily stage, 

13.5 feet June 20, 1918 (discharge, 48,400 second-feet); minimum stage and 

discharge occurred October 7, 1924.

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Numerous canals near Blackfoot and Idaho Falls divert practically 

the entire normal summer flow of Snake River.

REGULATION. Summer flow augmented by stored water from Jackson Lake for 

use on Minidoka and Twin Falls tracts. Considerable diurnal fluctuation 

at low stages due to operation of power plant 4 miles upstream.

ACCURACY. Stage-discharge relation fairly permanent; affected by ice December 

18 to January 2 and January 4-6. Rating curve well defined above 1,800 

second-feet. Operation of water-stage recorder satisfactory except for 

periods during winter when well was frozen. Daily discharge ascertained 

by application of mean daily gage height to rating table except as noted in 

footnote to table of daily discharge. Records excellent except for December 

and January for which they are good.

SNAKE RIVEE AT MILNER, IDAHO

LOCATION. In sec. 29, T. 10 S., R. 21 E., 500 yards below Milner Dam, at 

Milner, Twin Falls County. No tributaries enter Snake River between 

Minidoka station and Milner, and no noteworthy inflow between Milner 

and station near Twin Falls except seepage and spring water.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 10, 1909, to September 30, 1925.

GAGE. Friez water-stage recorder on left bank below highway bridge; inspected 

by McConnel and Gilham.

DISCHARGE MEASUREMENTS. Made from cable 400 yards above gage, from foot 

planks midway between gage and cable, or by wading.

CHANNEL AND CONTROL. Bed at gage composed of lava rock, overlain with 

very slight gravel deposits and occasional loose rock. Left bank high and 

steep; right bank confines flow in narrow gorge below 15-foot gage datum; 

full river width above that point. Control practically permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 18.44 feet at 

1 a. m. May 12 (discharge, 19,000 second-feet); minimum stage, 1.5 feet 

October 23-24 (discharge, 8 second-feet).

1909-1925: Maximum stage recorded, 20.1 feet (original gage) June 12, 

1909 (discharge, 44,400 second-feet); minimum stage, 1.5 feet August 22-26 

and October 23-24, 1924 (discharge, 8 second-feet).

ICE. Stage-discharge relation not seriously affected by ice.

DIVERSIONS. Twin Falls Canals divert water at Milner Dam, just above station. During part of the season practically entire flow of river is diverted 

by these canals.
SURFACE WATER SUPPLY, 1925, PART XII B

REGULATION. -Flow past station during irrigation season is regulated at .Milner 

Dam.

ACCTJKACT. Stage-discharge relation practically permanent. Rating curves 

fairly well defined. Operation of water-stage recorder satisfactory except 

during extremely low stages, when staff gage was read to hundredths twice 

daily. Daily discharge ascertained by applying mean daily gage height to 

rating table except on days when considerable fluctuation in stage occurred, 

when mean of hourly discharge was used. Records good.

COOPERATION. Gage-height record and three discharge measurements furnished 

by Twin Falls Canal Co.

deep lava canyon; very rough. Control formed by low falls 70 feet below 

gage; permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year from waterstage recorder, 13.3 feet from 4 to 6 a. m. May 12 (discharge, 18,000 secondfeet) ; minimum stage, 1.15 feet October 22-27 (discharge, 428 second-feet).

1923-1925: Maximum stage and discharge recorded May 12, 1915; minimum stage, 0.8 foot May 16-20, 1924 (discharge, 378 second-feet).

Icp. Stage-discharge relation not affected by ice.

DivERSioNs. No water diverted from the river between this station and station 

at Milner.

REGULATION. Flow past station is regulated directly by diversions of the North 

and South Side Canals at Milner, where practically the entire flow of the 

river is diverted during large part of irrigation season; flow at such times 

consists of inflow and seepage between this station and the one at Milner.

ACCURACY. Stage-discharge relation permanent. Rating curve fairly welldefined below 14,000 second-feet. Operation of water-stage recorder 

satisfactory except for few short periods. Daily discharge ascertained by 

applying to rating table mean daily gage height determined by inspection of 

recorder graph, except as indicated in footnote to table of daily discharge. 

Records good.

SNAKE RIVER NEAR HAGEBMAN, IDAHO

LOCATION. In sec. 2, T. 8 S., R. 13 E., one-eighth mile above Owsley Bridge, 

just above Upper Salmon Falls, and 4 miles south of Hagerman, Gooding 

County. Big Wood River enters 11 miles below.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. August 24, 1912, to June 18, 1917; July 25, 1919, to 

September 30, 1925.

GAGE. Friez water-stage recorder on right bank; installed April 20, 1921; 

inspected by F. M. Gregg.

DISCHARGE MEASUREMENTS. Made from cable 100 feet below gage.

CHANNEL AND CONTROL. Control rocky; permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 6.27 feet at 

11 a. m. May 12 (discharge, 24,100 second-feet); minimum stage, 3.30 feet 

at 6 a. m. October 1 (discharge, 5,080 second-feet).

1912-1917; 1919-1925: Maximum stage recorded, 7.75 feet at 6 p. m. 

June 10, 1914 (discharge, 35,100 second-feet); minimum stage, 3.1 feet

SNAKE RIVER 41

ICE] Stage-discharge relation not affected by ice.

DIVERSIONS. No noteworthy diversions between this station and the one at 

Milner. Practically entire flow of river is diverted at Milner during part of 

irrigation season by the Twin Falls Canals, and flow at Owsley Bridge is 

maintained largely by springs and waste water from irrigation above.

REGULATION. Flow directly regulated by diversions of the Twin Falls Canals 

at Milner.

ACCURACY. Stage-discharge relation changed March 18 to April 28. Standard 

rating curve well defined. Water-stage recorder operated satisfactorily 

except for short periods October to February. Daily discharge ascertained 

by applying to rating table mean daily gage height determined by inspecting 

recorder graph. Records good.

LOCATION. In sec. 7, T. 5 S., R. 11 E., 300 feet east of Oregon Short Line Railroad station at King Hill, Elmore County. Big Wood River enters from 

north 20 miles above station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 13, 1909, to September 30, 1925.

GAGE. Inclined staff set in concrete on right bank installed August 24, 1922; 

read by employee of United States Bureau of Reclamation.

DISCHARGE MEASUREMENTS. Made from cable 100 feet below gage.

CHANNEL AND CONTROL. Bed composed largely of gravel. Control is lava reef 

partly overlain with gravel; shifts slightly.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 11.24 feet ,at 

8 a. m. May 26 (discharge, 25,400 second-feet); minimum discharge, 6,710 

second-feet October 1-10, 24-27, and July 19-22.

1909-1925: Maximum stage recorded, 16.3 feet June 22, 1918 (discharge, 

47,200 second-feet); minimum stage, 4.5 feet July 7-9 and August 15 and 16, 

1910 (discharge, 4,760 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. No important diversions for irrigation are made between this 

station and the one at Milner.

REGULATION. Flow regulated by diversions at Milner. During certain parts of 

irrigation season practically the entire flow of river is appropriated, and flow 

at King Hill is derived largely from springs and seepage water from the Twin 

Falls tracts.

ACCURACY. Stage-discharge relation permanent during the year. Rating curve 

well denned. Gage read to hundredths once daily. Daily discharge ascertained by applying daily gage height to rating table. Records good.

COOPERATION. Gage-height record furnished by United States- Bureau of 

Reclamation.

SNAKE RIVER NEAR MURPHY, IDAHO

LOCATION. In NW. }/i sec. 18, T. 2 S., R. 1 E., Ada County, three-quarters 

of a mile below Swan Falls power plant, 9 miles northeast of Murphy, 

Owyhee County, and 38 miles below mouth of Bruneau River.

DRAINAGE AREA. 41,900 square miles (measured on United States Land Office 

maps).

3221 29 4
44 SURFACE WATER SUPPLY, 1925, PART XII B

RECORDS AVAILABLE. August 29 to October 31, 1912; August 21, 1913, to September 30, 1925.

GAGE. Au water-stage recorder on right bank a quarter of a mile below house 

on Glass ranch; installed July 31, 1924; inspected by George Bahler and 

J. G. Glass.

DISCHARGE MEASUREMENTS. Made from boat at ferry cable 1^ miles above

CHANNEL AND CONTROL. Bed composed1 of lava rock overlain with deposits of 

sand, silt, and gravel, where not scoured out by current. Control permanent. Banks not subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage during year, from water-stage 

recorder, 8.94 feet at 8.30 a. m. May 13 (discharge, 27,000 second-feet); 

minimum mean daily discharge, 6,830 second-feet October 1-3 and August 

10; absolute minimum stage and discharge not definitely known because 

water fell below intake pipe at times of minimum load at power plant above. 

1912-1925: Maximum stage recorded, 13.95 feet at 10 p. m. June 22, 

1918 (discharge, 47,300 second-feet); minimum stage, about 2.25 feet at 

6 a. m. August 6, 1917 (discharge, about 5,000 second-feet). Stage probably 

fell equally low at times of minimum load at power plant above during lowwater periods, 1919 to 1925, inclusive.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. A number of small pumping plants divert water for irrigation 

between this station and the one at King Hill.

REGULATION. Large diurnal fluctuations in stage are caused by operation of 

gates at dam above and by variation in load at power plant, but because of 

small relative amount of storage obtained, the changes are of short duration.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined. 

Operation of water-stagfe recorder satisfactory except for few short periods. 

Daily discharge ascertained by applying to rating table mean daily gage 

height obtained by inspection of recorder graph. Records good.

The following discharge measurements were made: 

May 1, 1925: Gage height, 4.62 feet; discharge, 12,300 second-feet. 

May 2, 1925: Gage height, 4.38 feet; discharge, 13,600 second-feet. 

July 28, 1925: Gage height, 1.41 feet; discharge, 8,660 second-feet.

SNAKE RIVER AT WEISER, IDAHO

LOCATION. In sec. 31, T. 11 N., R. 5 W., one-third mile above wagon bridge at 

Weiser, Washington County. Between this station and station near 

Murphy, Sucker Creek and Owyhee and Malheur Rivers enter Snake River 

from left and Boise, .Eayette, and Weiser .Rivers from right.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 8, 1910, to September 30, 1925. Fragmentary 

gage-height record obtained by United States Weather Bureau since 1895.

GAGE. Inclined concrete gage on right bank; read by J. W. Lapish. Elevation 

of zero of gage is at 2,087.22 feet above sea level.

DISCHARGE MEASUREMENTS. Made from cable 200 yards below bridge.

CHANNEL AND CONTROL. Bed composed of rocks and coarse gravel. One channel at all stages. Control fairly permanent.

EXTREMES OF DISCHARGE. Maximum discharge recorded during year, 63,100 

second-feet February 6; minimum stage, 2.02 feet October 4 (discharge, 

7,140 second-feet).

1910-1925: Maximum stage recorded, 13.60 feet May 23, 1921 (discharge, 

83,100 second-feet); minimum stage, 1.35 feet August 5, 1924 (discharge, 

5,100 second-feet), A stage of 15.7 feet was observed March 3, 1910, on 

old Weather Bureau gage (discharge, about 100,000 second-feet).

ICE. Stage-discharge relation affected by occasional ice jams during severe 

winters.
46 SURFACE WATER SUPPLY, 1925, PART XII B

DIVERSIONS. Some water is diverted by pumping, between Weiser and the 

station near Murphy.

REGULATION. Diurnal fluctuations during periods of low water due to operations 

at Swan Falls power plant above.

ACCURACY. Stage-discharge relation changed during ice-affected period December 22 to January 19 and again April 30 to May 19. A well-defined rating 

curve and two parallel curves used October 1 to December 21, January 20 

to April 29, and May 20 to September 30. Daily discharge ascertained by 

applying daily gage height to rating table; shifting-control method used 

April 30 to May 19. Records good except for estimated periods for which 

they are fair.

COOPERATION. Gage-height record furnished by United States Weather Bureau.

SNAKE RIVER AT OXBOW, OREG.

LOCATION. In NW. M sec. 16, T. 7 S., R. 48 E. Willamette meridian, at Oxbow 

station on Homestead branch of Oregon Short Line Railroad, Baker County, 

five-eighths mile above intake of diversion tunnel for Oxbow power plant, 

and \^i miles southeast of Copperfield post office.

DBAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 22, 1923, to September 30, 1925.

GAGE. Au water-stage recorder on left bank installed December 20, 1923; 

inspected by Wm. T. Kingsley and L. W. Goodin.

DISCHARGE MEASUREMENTS. Made from cable at gage.

CHANNEL AND CONTROL. Bed composed of gravel and boulders. Banks high; 

not subject to overflow. One channel at all stages. Control fairly permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year from waterstage recorder, 19.14 feet at 6 a. m. February 6 (discharge, about 70,600 

second-feet); minimum stage, 7.02 feet from 7 to 8 a. m. August 10 (discharge, 6,480 second-feet).

1923-1925: Maximum stage and discharge recorded February 6, 1925; 

minimum stage, 6.30 feet between 5 and 6 a. m. August 6, 1924 (discharge, 

4,890 second-feet).

ICE. Stage-discharge relation seldom affected by ice.

DIVERSIONS. A number of small pumping plants divert water for irrigation 

between this station and the one at Weiser.

REGULATION. Diurnal fluctuations during periods of low water due to operations of Swan Falls power plant above.

ACCURACY. Stage-discharge relation assumed to have changed slightly during 

ice-affected period December 23 to January 16. Rating curve used prior to 

shift is well defined between 5,000 and 31,000 second-feet; curve used thereafter well defined between 6,500 and 55,000 second-feet. Operation of 

water-stage recorder satisfactory except for short periods in December and 

January when float froze in well. Daily discharge ascertained by applying 

to rating table mean daily gage height determined by inspection of recorder 

graph. Records good except for estimated periods for which they are fair.

DIVERSIONS FROM HENRYS FORK BETWEEN ASHTON AND ST. ANTHONY GAGING STATIONS,

IDAHO

Between Ashton and St. Anthony gaging stations six separate canals divert 

water from Henrys Fork for irrigation. Gaging stations are maintained at 

headings of each canal by the United States Geological Survey for the Idaho 

State Department of Reclamation to facilitate distribution of water. Records 

are available from June 1, 1919, to September 30, 1925.

Stage-discharge relation on most of the canals afifected by growth of aquatic 

plants or by operation of check gates. Rating curves well defined. Gages read 

to hundredths daily except during September, when occasional readings were 

made. Records good.

DIVERSIONS FROM HENRYS FORE BETWEEN ST. ANTHONY AND REXBURG GAGING

STATIONS, IDAHO

Between St. Anthony and Rexburg gaging stations four separate canals divert 

water from Henrys Fork for irrigation. Gaging stations are maintained at 

heading of each canal by the United States Geological Survey for the Idaho 

State Department of Reclamation to facilitiate the distribution of the water. 

Records are available from June, 1919, to September 30, 1925.

Stage-discharge relation on most of the canals affected by the growth of 

aquatic plants or by the operation of check gates. Rating curves well defined. 

Gages read to hundredths daily except during September, when occasional 

readings were made. Records good.

Combined daily discharge, in second-feet, of canals diverting from Henrys Fork 

between St. Anthony and Rexburg gaging stations, for the irrigation season of 

1925

DIVERSIONS FROM FALL RIVER ABOVE GAGING STATION NEAR SQUIRREL, IDAHO

Above the gaging station near Squirrel three separate canals divert water 

from Fall River for irrigation. Gaging stations are maintained at heading of 

each canal by the United States Geological Survey for the Idaho State Department of Reclamation to facilitate distribution of the water. Records are available from June 1, 1919, to September 30, 1925.

Stage-discharge relation of these canals affected by growth of aquatic plants. 

Rating curves fairly well defined. Gages read to hundredths daily except during September, when occasional readings were made. Records good.
TRIBUTARY BASINS

Combined daily discharge, in second-feet, of canals diverting from Fall River above 

gaging station near Squirrel, Idaho, for the irrigation season of 1925

LOCATION. In sec. 35, T. 9 N., R. 44 E., 9 miles southeast of Marysville and

4 miles northeast of Squirrel post office, Fremont County. Marysville

Canal diverts half a mile upstream. This station was formerly known as

"Fall River near Fremont." 

DRAINAGE AREA. 390 square miles. 

RECORDS AVAILABLE. January 1, 1904, to June 30, 1909; May 2, 1918, to

September 30, 1925. At Wilson's sawmill, 3 miles above present site,

August 24, 1902, to December 31, 1903. 

GAGE. Vertical staff on left bank installed January 1, 1904; read by T. W. and

J. D. Luetjen.

DISCHARGE MEASUREMENTS. Made from cable 200 feet below gage or by wading. 

CHANNEL AND CONTROL. Bed composed of boulders in gravel drift. Control

formed by riffie below gage; fairly permanent. Banks high, clean, and not

subject to overflow. One channel at all stages. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.68 feet at

7.30 p. m. May 23 (discharge, 3,650 second-feet); minimum stage not

recorded.

1904-1909, 1918-1925: Maximum stage recorded, 5.6 feet June 14, 15,

and 23, 1918 (discharge, 5,380 second-feet); minimum stage, 1.46 feet at

1 p. m. January 19, 1924 (discharge, 124 second-feet).

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Three irrigation canals divert above station.

REGULATION. None except that due to head-gate changes of canals above 

station.

ACCURACY. Stage-discharge relation remained practically permanent after iceaffected period December 15 to February 21. One rating curve parallel to 

standard shape but slightly lower in discharge used throughout open-water 

period; fairly well defined by measurements at medium low and high stages. 

Gage read to hundredths daily. Daily discharge determined by application 

of daily gage height to rating table. Records good except during iceaffected period for which they are fair.

DIVERSIONS FROM FAIL RIVER BETWEEN SQTJIRREI AND CHESTER GAGING STATIONS, IDAHO

Between Squirrel and Chester gaging stations nine separate canals divert 

water from Fall River for irrigation. Gaging stations are maintained at heading 

of each canal by the United States Geological Survey for the Idaho State Department of Reclamation to facilitate distribution of water. Records are available 

from June 1, 1919, to September 30, 1925.

Stage-discharge relation on most of the canals affected by growth of aquatic 

vegetation or by operation of check gates. Rating curves fairly well defined. 

Gage read to hundredths daily except during September, when occasional readings are made. Records good.

Combined daily discharge, in second-feet, of canals diverting from Fall River between 

Squirrel and Chester gaging stations, for the irrigation season of 1925

DIVERSIONS FROM TETON RIVER BETWEEN GAGING STATION NEAR ST. ANTHONY AND

MOUTH OF RIVER, IDAHO

Between St. Anthony gaging station and the mouth of the stream 14 separate 

canals divert water from Teton River for irrigation. Gaging stations are maintained at heading of each canal by the United States Geological Survey for the 

Idaho State Department of Reclamation to facilitate distribution of the water. 

Records are available from June 1, 1919, to September 30, 1925.

The stage-discharge relation on these canals is affected by growth of aquatic 

plants. Rating curves are only fairly weU defined. Gages read to hundredths 

daily except during September, when occasional readings were made. Records 

fair.

Combined daily discharge, in second-feet, of canals diverting from Teton River 

between the St. Anthony gaging station and the mouth of the river, for the irrigation season of 1925

GRAYS LAKE OUTLET NEAR HERMAN, IDAHO

LOCATION. In sec. 15, T. 3 S., R. 42 E., 3 miles below bridge at outlet of lake 

and 3J^ miles west of Herman, Bonneville County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 5, 1916, to September 30, 1925, when records were 

discontinued.

GAGE. Stevens continuous water-stage recorder on right bank; installed April 

20, 1918; inspected by Emory Poulson.

DISCHARGE MEASUREMENTS. Made from cable near gage or by wading.

CHANNEL AND CONTROL. Channel composed of gravel and small cobbles; left 

bank subject to overflow at gage height of about 3.5 feet. Control is rock 

ledge 25 feet below gage; practically permanent. Point of zero flow determined September 17, 1924, as at gage height 0.45 foot ±0.05 foot.

EXTREMES OF DISCHARGE. Maximum stage recorded during year from waterstage recorder, 2.96 feet from 1 to 2 p. m. May 30 (discharge, 214 secondfeet); minimum stage, 0.83 foot from 5 to 10 p. m. September 12 (discharge, 

2.3 second-feet).

1916-1925: Maximum stage recorded, 5.9 feet at 9 a. m. May 15, 1917 

(discharge, 1,350 second-feet); minimum stage, 0.63 foot August 30 and 31, 

1920 (discharge, 0.5 second-foot).

ICE. Ice practically stops flow from lake at times, but springs probably keep 

channel near gage free from ice. Observations discontinued during winter.

DIVERSIONS. No diversions between outlet of lake and station. Diversions for 

irrigation are made above lake, but amount of water so diverted is not 

known. On May 25, 1924, United States Office of Indian Affairs completed 

a dam at outlet of lake and after that date water has been diverted from 

south end of lake through Clark Cut into Meadow Creek Basin and thence 

into Blackfoot-Marsh Reservoir.

REGULATION. Flow past station is regulated by head gate in dam at outlet of 

lake.

ACCURACY. Stage-discharge relation permanent. Rating curve well denned below 250 second-feet. Operation of water-stage recorder satisfactory. Daily 

discharge ascertained by applying to rating table mean daily gage height 

obtained by inspection of recorder graph except as indicated in footnote to 

table of daily discharge. Records good.

County, and 45 miles southeast of Blackfoot.

RECORDS AVAILABLE. January 1, 1912, to September 30, 1925.

<*AGE. Vertical staff near spillway at right'end of dam; read to hundredths by 

B. B. Reynolds. Gage datum was raised 51.6 feet on April 23, 1918, but 

subsequent readings have been reduced to original datum. To reduce published gage heights to elevation above sea level add 6,048.40 feet.
78 SURFACE WATER SUPPLY, 1925, PART XII B

EXTREMES OP STAGE. Maximum stage recorded, 60.39 feet July 10 and 11; 

minimum stage, 43.25 feet October 2.

1912-1925: Maximum stage recorded, 68.60 feet June 27-30, 1912; minimum stage, 40.76 feet September 28 and 29, 1919. 

COOPERATION. Gage-height record furnished by United States Office of Indian

Affairs.

Stored water from this reservoir is used for irrigation of lands near Poqatello 

and on Fort Hall Indian Reservation, the area covered by the project being 

about 50,000 acres. The reservoir1 is formed by a loose rock and hydraulic-fill 

dam with a concrete core wall, paved on the reservoir side to prevent erosion. 

The dam is 120 feet long at base, 250 feet long at crest, and about 40 feet high, 

the elevation at crest being 6,132.0 feet. The reservoir is 17 miles long and 5J^ 

miles wide at the widest point, and covers about 15,000 acres of land. The 

spillway, excavated in rock at north end of dam, is 50 feet wide, and the crest 

elevation is 6,118.5 feet at which elevation the capacity of reservoir is 312,000 

acre-feet. Since reconstruction of spillway in 1924 and 1925, provision has been 

made by means of flashboards to store water to an elevation of 6,124 feet, at 

which elevation the capacity of reservoir is 409,000 acre-feet. Elevation at 

lowest point to which water may be drawn is 6,086 feet. The present distribution system comprises 61 miles of main canal, 128 miles of laterals, and llj^ 

miles of drainage ditch.

LOCATION. In sec. 7, T. 2 S., R. 38 E., 1% miles above mouth of canyon, 3 miles 

above N. A. Just ranch, 10 miles southeast of Shelley, Bingham County, 

and 18 miles northeast of Blackfoot. Below all large tributaries.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. June 26, 1909, to September 30, 1925. March .23, 1903, 

to December 31, 1909, records were obtained near Presto, 5 miles below 

present site. No tributaries enter between the two sites, but during the 

irrigation season several canals divert about 50 second-feet.

GAGE. Friez water-stage recorder on right bank; inspected by R. E. Reid and 

M. A. Jensen.

DISCHARGE MEASUREMENTS. Made by wading or from cable at gage.

CHANNEL AND CONTROL. Bed rocky and rough. One channel at all stages. 

Control shifts occasionally.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage 

recorder, 5.16 feet at 4 p. m. July 21 (discharge, 1,030 second-feet); minimum 

stage probably occurred during period when ice affected stage-discharge 

relation.

1909-1925: Maximum stage recorded, 6.30 feet at 9 p. m. July 23, 1923 

(discharge, 1,830 second-feet); minimum stage, 2.83 feet at midnight 

January 23, 1919 (discharge, about 15 second-feet). Ice jam above station 

caused temporary drop in stage.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. No noteworthy diversions are made from river or tributaries above 

station.

REGULATION. Flow regulated by storage in Blackfoot-Marsh Reservoir of 

United States Office of Indian Affairs, about 40 miles upstream.

ACCURACY. Stage-discharge relation not permanent; affected by ice December 

6 to January 23. Standard rating curve well defined. Operation of waterstage recorder fairly satisfactory except during winter, when occasional staff 

readings were obtained. Daily discharge ascertained by applying to rating 

table mean daily gage height obtained by inspecting recorder graph or from 

staff gage readings. Open-water records, good; from December to February, 

fair.

BLACKFOOT RIVER NEAR BLACKFOOT, IDAHO

LOCATION. In sec. 27, T. 3 S., R. 34 E., 2 miles above junction of Blackfoot 

River with Snake River and 8 miles southwest of Blackfoot, Bingham 

County.

DBAINAQE AREA. Not measured.
TEIBUTABY BASINS 83

RECORDS AVAILABLE. July 27, 1913, to September 30, 1925.

GAGE. Inclined staff on right bank, half a mile south of Kofoed ranch house; 

read by Eva Davis.

DISCHARGE MEASUREMENTS. Made by wading or from cable 100 yards below 

gage.

CHANNEL AND CONTROL. Bed composed of gravel. Control presumably of 

same material; fairly permanent. One channel at all stages. Banks 

covered with heavy growth of brush and willows which may affect stagedischarge relation at high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 8.58 feet 

at 11 a. m. September 23 (discharge, 696 second-feet); minimum stage, 4.08 

feet at 12.20 p. m. July 15 (discharge, 2 second-feet).

1913-1925: Maximum stage recorded, 9.6 feet at 12.30 p. m. May 21,1921 

(discharge, 868 second-feet); no flow on numerous days in 1919, 1921, and 

1924.

ICE. No records obtained during winter.

DIVERSIONS. Principal diversions above gage are the Fort Hall canals near 

Blackfoot; several smaller diversions also made near Blackfoot.

REGULATION. Flow regulated by storage in Blackfoot-Marsh Reservoir of the 

United States Office of Indian Affairs and by manipulation of canal head 

gates above station.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve 

well defined below 500 second-feet and fairly well defined above that stage 

Gage read to hundredths daily; diurnal changes in stage caused by regula 

tion are often source of error. Daily discharge ascertained by applying 

gage height to rating table; shifting-control method used June 23 to July 14. 

Records fair.

MEADOW CREEK NEAR HENRt, IDAHO

LOCATION. In sec. 3, T. 6 S., R. 42 E., half a mile above flow line of BlackfootMarsh Reservoir, three-fourths mile below Goose Lake or Pelican Slough, 

and 1% miles northeast of Henry, Caribou County.

DRAINAGE ABBA. Not measured.

RECORDS AVAILABLE. April 20, 1914, to September 30, 1925.

GAGE. Stevens continuous water-stage recorder on left bank; installed June 27, 

1914; inspected by Mrs. W. J. Chester.
86 SURFACE WATER SUPPLY, 1925, PART XII B

DISCHARGE MEASUREMENTS. Made from cable at gage or by wading.

CHANNEL AND CONIROL. Bed composed of rock and gravel. One channel at 

all stages. Banks very brushy. Control somewhat shifting.

EXTREMES OP DISCHARGE. Maximum stage recorded during year from waterstage recorder, 4.28 feet at 4 a. m. April 18 (discharge, 321 second-feet); 

minimum stage, 1.60 feet October 10 (discharge, 8.5 second-feet).

1914-1925: Maximum stage recorded, 4.81 feet May 17, 1917 (discharge, 

424 second-feet; minimum discharge probably somewhat less than 0.5 

second-foot during July, 1919.

ICE. Stage-discharge relation seriously affected by ice; observations discontinued 

during winter.

DIVERSIONS. Several small irrigation diversions above gage.

REGULATION. None prior to June, 1924. After that time some water diverted 

from Grays Lake through Clark Cut into Meadow Creek above station.

ACCURACY. Stage-discharge relation not permanent owing to accumulation and 

removal of moss and debris on control. Standard rating curve fairly well 

defined. Operation of water-stage recorder unsatisfactory at times owing 

to clock trouble. Daily discharge ascertained by applying to rating table 

mean daily gage height determined by inspection of recorder graph, except 

as noted in footnote to daily-discharge table. Records fair for low water 

and interpolated periods; others good.

COOPERATION. One discharge measurement furnished by United States Office 

of Indian Affairs.

NOTE. Error in readings from Magill gage caused by action of ice Dec. 26 to Feb. 18 and by action of 

wind Oct. 3, 4, and Sept. 6; contents determined from gage-height graph based on readings from gage 

at Oswley Canal Go's pump house.

CAMAS CREEK NEAR DUBOIS, IDAHO

LOCATION. In NE. H SE. % sec. 13, T. 11 N.,R. 38 E.,2 miles north of Lone 

Tree Reservoir, 2 miles downstream from 18-mile shearing corral, 5J^ miles 

south of Idmon, and 19 miles northeast of Dubois, Clark County. Station 

is 26 miles north (upstream) of gage on Camas Creek near Camas.

DRAINAGE AREA. 216 square miles (measured on United States Geological 

Survey map of Mud Lake Basin).

RECORDS AVAILABLE. April 11, 1921, to September 30, 1925.

GAGE. Stevens continuous water-stage recorder on right bank; inspected by 

Survey engineers.

DISCHARGE MEASUREMENTS. Made at high stages from wagon bridge 2 miles 

above gage at which point during extreme high stages water flows in a flood 

channel to the left of main channel and unites above gage. Measured by 

wading at low and medium stages 700 feet above gage.

CHANNEL AND CONTROL. Bed composed of lava boulders and gravel; practically 

permanent. Banks fairly high and brushy; right bank subject to overflow. 

Control well defined.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.39 feet at 

4 p. m. April 18 (discharge, 848 second-feet); minimum stage, 0.82 foot from 

noon October 1 to 4 a. m. October 2 (discharge, 15 second-feet).

1921-1925: Maximum stage recorded, 5.75 feet probably on May 21, 1922 

(discharge, 1,550 second-feet); minimum stage, 0.65 foot from 4 p. m. June 5 

to 9 a. m. June 6, 1924 (discharge, 8.5 second-feet).

ICE. Stage-discharge relation seriously affected by ice. Records discontinued 

during winter.

DIVERSIONS. Two stock-watering ditches of the Wood Live Stock Co. are the 

principal diversions above station. In addition, a number of small irrigation 

ditches divert water from tributaries above.

REGULATION. Some water stored in Frazier Reservoir, which has a capacity of 

from 2,000 to 3,000 acre-feet, on West Camas Creek, and released during 

low-water period for use above gaging station.

ACCURACY. Stage-discharge relation changed during winter. Rating curves 

well defined. Operation of water-stage recorder satisfactory. Daily discharge ascertained by applying to rating table mean daily gage height 

determined by inspection of recorder graph except as noted in footnote to 

table of daily discharge. Records excellent except April to June which are 

good; estimated periods fair.

by wading.

CHANNEL AND CONTROL. Bed composed of lava covered in places by gravel. 

Control formed by lava boulders; well detined. Banks high; one channel at 

all stages.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage 

recorder, 2.13 feet at 4 a. m. April 22 (discharge, 150 second-feet); minimum 

discharge occurred during winter and was not accurately determined.

1921-1925: Maximum stage recorded, 4.82 feet at 9.30 a. m. May 22, 

1922 (discharge, 645 second-feet); minimum stage, 0.06 foot from 10 

p. m. July 5 to 2 a. m. July 6, 1924 (discharge, 2.6 second-feet).

ICE. Stage-discharge relation seriously affected by ice.

CAMAS CREEK AT CAMAS, IDAHO

LOCATION. In E. ^ SE. J^ sec. 21, T. 8 N., R. 36 E., half a mile above mouth of 

Beaver Creek, 350 feet above bridge of Oregon Short Line Railroad at 

Camas, Jefferson County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 13 to September 30, 1925.

GAGE. Vertical staff on right bank; read by William McCall. Prior to August 

21 gage was located 800 feet downstream on left bank and at different 

datum from present site.

DISCHARGE MEASUREMENTS. Made from wagon bridge 300 feet below gage or 

by wading.

CHANNEL AND CONTROL. Bed composed of fine gravel and sand. Control not 

well defined; subject to growth of aquatic plants. Banks low; several 

channels at high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during period, 1.53 feet 

April 23 (discharge, 134 second-feet); minimum discharge, 11 second-feet 

July 2.

DIVERSIONS. A number of irrigation and stock water diversions above station.

REGULATION. Flow past station affected to some extent by losses through lava 

crevices in Lone Tree * Reservoir, 29 miles upstream. Gates in dam not 

changed during year.

ACCURACY. Stage-discharge relation changed frequently owing to moss growth 

below present gage and to stock trampling on control below gage in use prior 

to August 21. Shifting-control method used, based on actual discharge 

measurements referred to two standard rating curves; the first applicable 

April 13 to August 20 for original gage and the second applicable August 21 

to September 30 for gage at present site. Gage read to hundredths once 

daily. Daily discharge obtained by applying daily gage height to rating 

table except as indicated in footnote to table of daily discharge. Records 

fair.

COOPERATION. Gage-height record furnished by Camas Mutual Irrigation 

District.

BEAVER CREEK AT DUBOIS, IDAHO

LOCATION. In NW. M sec. 21, T. 10 N., R. 36 E., at Ed F. Palmer ranch, half

a mile north of Dubois, Clark County. This stream is locally known as

Dry Creek. 

DRAINAGE AREA. 220 square miles (measured on United States Geological

Survey map of Mud Lake drainage basin). 

RECORDS AVAILABLE. April 15, 1921, to September 30, 1925. 

GAGE. Vertical staff attached to cottonwood tree on left bank, 25 feet below

wagon bridge; read by W. L. Miller.

DISCHARGE MEASUREMENTS. Made from wagon bridge or by wading. 

CHANNEL AND CONTROL. Bed composed of lava rock and gravel. Control

fairly well defined but occasionally fouled by drift. Banks steep and brushy;

one channel at all stages. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.50 feet at

10.30 a. m. April 12 (discharge, about 463 second-feet); channel probably dry

October and November with very little flow thereafter prior to March 16. 

1921-1925: Maximum stage recorded, 4.9 feet May 20, 1922 (discharge,

637 second-feet); stream reported dry August 3 to about November 30, 1924. 

[CE. Stage-discharge relation seriously affected by ice.
94 SURFACE WATER SUPPLY, 1925, PART XII B

DIVERSIONS. A few small diversions several miles upstream. After high water 

practically the entire flow is diverted below gage for irrigation.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Rating curve fairly well 

defined below 250 second-feet used April 2 to July 10; shifting-control 

method used thereafter. Gage read to hundredths twice daily April 12 to 

June 15; once daily at other times. Daily discharge ascertained by applying 

daily gage height or mean daily gage height to rating table. Records fair 

except for estimated periods for which they are poor.

gage or by wading.

CHANNEL AND CONTROL. Bed composed of gravel; shifts occasionally. One 

channel at low and medium stages; right bank is overflowed at high stages. 

Control fairly well defined.

EXTREMES OF DISCHARGE. Maximum mean daily stage recorded during year, 

3.14 feet June 23 (discharge, 775 second-feet); channel reported dry November 1 to May 7.

1919-1925: Maximum stage recorded, 3.37 feet June 16, 1922 (discharge, 

999 second-feet); no flow April 27 to May 16,1920, in winter of 1923, for long 

periods in 1924, and January 1 to May 7, 1925.

ICE. Stage-discharge relation affected by ice; no flow during winter 1924-25.

DIVERSIONS. None between gage and reservoir. Several canals divert water in 

vicinity of Chilly above "dry beds" which extend from a few miles above 

gage to a point about 15 miles above.

REGULATION. None.
102 SURFACE WATER SUPPLY, 1925, PART XII B

ACCURACY. Stage-discharge relation changed slightly during period of no flow.

Rating curves well defined. Operation of water-stage recorder satisfactory.

height obtained by inspection of recorder graph. Records good except for

estimated periods, which are fair. 

COOPERATION. Gage-height record and two discharge measurements furnished

by water commissioner for Big Lost River.

The record at this station represents part of the natural flow of Big Lost River 

and, taken in conjunction with the record for west channel of Big Lost River 

and with the record for east and west channels of Warm Spring Creek, will show 

the entire flow of Big Lost River at this point. The combined flow of Big Lost 

River and Warm Spring Creek represents practically the entire surface flow at 

this point into Mackay Reservoir situated a short distance below. For record at 

station on west channel of river and on east and west channels of Warm Spring 

Creek see pages 103,110, and 112, respectively. For combined flow of both channels of Big Lost River and both channels of Warm Spring Creek see page 105.

MACKAY RESERVOIR NEAR MACKAY, IDAHO

LOCATION. In sec. 12, T. 7 N., R. 23 E., 4 miles northwest of Mackay, Ouster

County.

RECORDS AVAILABLE. January 1, 1919, to September 30, 1925. 

GAGE. Vertical staff on head-gate tower near right end of dam; read to hundredths once daily by employees of Utah Construction Co. Datum of gage

6,000 feet above sea level. 

EXTREMES OF CONTENTS. Maximum stage recorded during year, 55.40 feet July

9 (contents, 30,470 acre-feet); minimum stage, 7.40 feet October 20-30

(contents, 67 acre-feet).

1919-1925: Maximum stage recorded, 63.62 feet June 26, 1922 (contents,

40,500 acre-feet); minimum contents, water surface below bottom of outlet

tunnel August 1 to October 19, 1919, August 5, 17-27, 31, September 1-5,

12-14, and 18, 1920, and August 5, 1924 (minimum stage during these

periods, 6.6 feet August 24 to September 2, 1919). 

CooJPERATroN. Gage-height record furnished by Utah Construction Co. through

water commissioner for Big Lost River.

Stored water from this reservoir is used for irrigation of land near Arco, under 

Utah Construction Co.'s Carey Act project. About 5,100 acres is under cultivation at present, but this area is subject to change from year to year. The 

reservoir is formed by a gravity earth dam 750 feet in length at crest. The crest 

is 75 feet above bottom of concrete core wall below which there is 15 feet of sheet 

piling to prevent excessive seepage. Crest of spillway is 10 feet below crest of 

dam and 55 feet above bottom of outlet tunnel. Elevation of bottom of outlet 

tunnel corresponds to 7.0 feet on gage, at which stage the usable storage is zero, 

although there is about 125 acre-feet of water in reservoir, which is not available 

for use. Elevation of crest of spillway corresponds to 62.0 feet on gage, at which 

stage capacity of reservoir is 38,400 acre-feet, about 2,400 acres of land being 

submerged. As foundation of dam is located on very porous material and core 

wall does not penetrate to bedrock, heavy seepage loss occurs, and at times during 

low water the inflow is not sufficient to counteract this loss plus the loss sustained 

by evaporation. Thus the stage of water in reservoir occasionally falls below 

bottom of the outlet tunnel. A study of stream-flow records at this point indicates that most of the seepage from the reservoir reappears in river channel 

above gaging station at the "Narrows" 1J^ miles downstream, where favorable 

rock structure forces underground water to the surface. Additional water also 

appears, part of which is probably side drainage and part evidently flows
TRIBUTARY BASINS 107

underground at places where the surface flow into the reservoir is measured and 

thence through reservoir. Seepage loss will probably diminish as silting takes 

place, although the amount of water thus lost has not varied appreciably in the 

last few years.

BIG IOST RIVER BELOW MACKAY RESERVOIR, NEAR MACKAY, IDAHO

LOCATION. In sec. 18, T. 7 N., R. 24 E., 450 feet below Oleison suspension 

bridge, half a mile above heading of Streeter ditch, 1J^ miles below Mackay 

Dam, and 2J^ miles above Mackay, Ouster County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. December 1, 1903, to August 31, 1906; May 12, 1912, 

to March 15, 1915; January 1, 1919, to September 30, 1925.

GAGE. Friez water-stage recorder on left bank; installed May 4, 1920; inspected by employees of Utah Construction Co. From April 29, 1913, to 

March 15, 1915, records were obtained at what is commonly known as the 

Streeter gage, a vertical staff located 1 mile below present site. Streeter 

ditch diverts water between these two points.

DISCHARGE MEASUREMENTS. Made from cable just below gage cr by wading.

CHANNEL AND CONTROL. Bed composed of gravel; shifts occasionally. Moss 

growth at times affects stage-discharge relation.

EXTREMES OP DISCHARGE. Maximum mean daily stage recorded during year, 

3.97 feet May 22 (discharge, 1,380 second-feet); minimum stage, 1.22 feet 

November 2 (discharge, 38 second-feet).

1903-1906; 1912-1915; 1919-1925: Maximum stage recorded, 5.79 feet 

June 10, 1921 (discharge, 2,990 second-feet); minimum discharge, November 2, 1924. 

3221 29 8
108 SURFACE WATER SUPPLY, 1925, PART XII B

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Numerous diversions above Mackay Reservoir but Sharp ditch 

is only diversion between gage and reservoir.

REGULATION. Flow past gage regulated by operation of gates in Mackay Dam. 

Prior to 1917 regulation from storage above was practically negligible.

ACCTJKACT. Stage-discharge relation changed very slightly during October and 

during high water in June. Standard rating curve well defined. Operation of water-stage recorder satisfactory. Daily discharge ascertained by 

applying to rating table mean daily gage height determined by inspecting 

recorder graph. Records excellent.

COOPERATION. Gage-height record and two discharge measurements furnished 

by water commissioner for Big Lost River.

411 second-feet); minimum stage and discharge, May 7, 1925.

ICE. Stage-discharge relation occasionally affected by ice.

DIVERSIONS. Practically entire flow diverted during irrigation season. Flow 

during summer represents return flow from irrigation above. Entire flow 

impounded in Mackay Reservoir below.

REGULATION. None.

ACCURACY. Stage-discharge relation changed January 14 to February 21 and July 

1-30. Rating curve well defined between 70 and 170 second-feet and fairly 

well defined above, and curves parallel thereto, used February 22 to June 30, 

October 1 to January 13, and July 31 to September 30, respectively; shiftingcontrol method used at other times. Operation of water-stage recorder 

satisfactory. Daily discharge ascertained by applying to rating table mean 

daily gage height obtained by inspection of recorder graph. May to July, 

records fair; others good.

DIVERSIONS. None between gage and head gates and none for some distance

below. Surplus water may be discharged into river through waste gates

about 200 feet below head of canal. 

REGULATION. Flow fegulated by head and waste gates. 

ACCURACY. Stage-discharge relation not permanent; affected by growth of

aquatic plants in summer and by ice December 18-31 and January 6-24.

Three standard rating curves well defined. Operation of water-stage

recorder satisfactory except for periods during December and January when

well was frozen; staff gage read to hundredths once daily November 1 to

March 31 and twice daily for remainder of year. Daily discharge obtained

by applying to rating table mean daily gage height obtained from staff

reading or by inspecting recorder graph, averaging discharges on days of

considerable fluctuation. Records good. 

COOPERATION. Gage-height record and 44 discharge measurements furnished by

North Side Canal Co. (Ltd.).

North Side Twin Falls Canal diverts water from north side of Snake River at 

Milner Dam and furnishes water for stock and irrigation on about 240,000 acres 

of land in Jerome, Lincoln, and Gooding Counties. The distribution system 

comprises about 100 miles of main canal and 625 miles of laterals.

SOUTH SIDE TWIST FAILS CANAL AT MILNER, IDAHO

LOCATION. In sec. 29, T. 10 S., R. 21 E., at wagon bridge one-eighth mile below 

head gates at Milner, Twin Falls County.

RECORDS AVAILABLE. May 10, 1909, to September 30, 1925.

GAGE. Friez water-stage recorder on left bank, at site and datum of vertical 

staff gage installed early in summer of 1912; staff gage has been used since 

that time for stages above 5.3 feet. Inspected by McConnel and Gilham.

DISCHARGE MEASUREMENTS. Made from cable 50 feet above gage or by wading.

CHANNEL AND CONTROL. Channel at gage blasted out of rock; practically permanent. Occasional slight changes in control are due to deposition of silt.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 10.61 feet 

at 8 p. m. June 11 (discharge, 3,710 second-feet); minimum stage probably 

occurred at stage lower than water-stage recorder could register.

1909-1925: Maximum discharge, 4,600 second-feet August 12, 1918; 

canal dry September 20, 1920.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. None above gage and no sizable ones for several miles below.

REGULATION. Flow regulated by head gates.

ACCURACY. Stage-discharge relation not permanent; affected by ice December 

17 to January 1, January 3 to February 2, and February 4. Standard 

rating curve well denned. Operation of water-stage recorder satisfactory 

except for short periods in January and March when stage was lower than 

recorder could register. Staff gage read twice daily to hundredths during 

these periods. Daily discharge ascertained by applying to rating table 

mean daily gage height obtained by inspection of recorder graph or from 

staff gage readings. Discharges were averaged on days of large fluctuation. 

Shifting-control method used during several periods. Records good.

COOPERATION. Gage-height record and 20 discharge measurements furnished 

by Twin Falls Canal Co.

South Side Twin Falls Canal diverts water from south side of Snake River 

at Milner Dam and furnishes water for stock and irrigation on about 200,000 

acres of land near Twin Falls. The distribution system comprises about 110 

miles of main canal and 590 miles of laterals.

ROCK CREEK NEAR TWIN FAILS, IDAHO

LOCATION. On south line of sec. 36, T. 9 S., R. 16 E., at highway bridge, 3 

miles above confluence with Snake River and 3J^ miles northwest of Twin 

Falls, Twin Falls County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 27, 1922, to September 30, 1925.

GAGE. Friez water-stage recorder on right bank; installed July 31, 1922; inspected by T. T. Rutledge.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of lava rock covered with boulders, 

gravel, and silt. One channel at all stages. Banks high; covered with 

brush. Control formed by lava reef covered in part by boulders and brush 

growth; fairly permanent.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage 

recorder, 4.70 feet at 5 p. m. January 29 (discharge, 939 second-feet); 

minimum discharge, 112 second-feet November 28.

1922-1925: Maximum stage and discharge recorded occurred January 29, 

1925; minimum stage, 1.01 feet from 3 p. m. to midnight August 3, 1924 

(discharge, 94. second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. After spring floods the normal flow is entirely diverted for irrigation several miles upstream. Flow past gage derived largely from waste 

and seepage water from the South Side Twin Falls tract.

REGULATION. At times waste water from South Side Twin Falls Canal which 

crosses Rock Creek 10 miles above causes appreciable changes in stage.

ACCURACY. Stage-discharge relation not permanent. Rating curves well defined below 375 second-feet and extended above. Operation of water-stage 

recorder satisfactory except for short periods. Daily discharge ascertained 

by applying to rating table mean daily gage height determined from inspection of recorder graph except as indicated in footnote to table of daily discharge. Shifting-control method used January 29, 30, and June 16-18. 

Records good except for stages above 375 second-feet for which they are 

fair, and for estimated periods for which they are poor.

COOPERATION. Gage-height record furnished by Murtaugh Irrigation District.

BIG WOOD RIVER AT HAHEY, IDAHO

LOCATION. In sec. 9, T. 2 N., R. 18 E., at steel highway bridge a quarter of a

mile southwest of Hailey, Blaine County.

DRAINAGE AREA. 640 square miles (measured on topographic maps). 

RECORDS AVAILABLE. June 11, 1915, to September 30, 1925. 

GAGE. Vertical staff on right bank; installed October 2, 1922; read by R. F.

Bowman and C. J. Bradley.
TRIBUTARY BASINS 137

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of coarse gravel and sand; clean. 

Banks low; covered with light brush. Log cribbing along left bank constructed in April, 1922, prevents overflow and confines flood discharge in 

one channel. Control subject to change at high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 5.45 feet at 

7.15 a. m. May 21 (discharge, 2,710 second-feet); minimum discharge, 0.1 

second-foot October 2-9.

1915-1925: Maximum stage recorded, 5.70 feet June 12, 1921 (discharge, 

3,560 second-feet); minimum discharge, 0.1 second-foot September 10-20 

and October 2-9, 1924.

ICE. Stage-discharge relation slightly affected by ice.

DIVERSIONS. A number of small diversions for irrigation, principally from 

tributaries, are made above station. Hailey power plant, half a mile 

upstream, utilizes as a tailrace a natural channel on east side of river known 

as Big Wood Slough. A large amount of water is diverted from main stream 

in this manner and is returned to river below station. A record of flow of 

Big Wood Slough is being obtained (see p. 150), and the total flow of Big 

Wood River is represented by amount of water passing both stations.

REGULATION. Variation in the amount of water used at Hailey power plant 

causes some diurnal fluctuation at gage, but as observations on the river 

and on Big Wood Slough are practically simultaneous each day, the effect 

of such regulation is probably eliminated.

ACCURACY. Stage-discharge relation changed very slightly during winter and 

twice during spring flow. Rating curves well defined. Gage read to hundredths twice daily April 8 to August 30 and once daily at other times 

except during winter. Daily discharge ascertained by applying daily and 

mean daily gage height to rating table except as indicated in footnote to 

table of daily discharge. Records on the whole are good; poor for estimated 

periods when flow was practically negligible.

COOPERATION. Four discharge measurements furnished by water master for 

Big Wood and Little Wood Rivers.

Tables of combined discharge of Big Wood River and Big Wood Slough are 

published herein.

MAGIC RESERVOIR WEAR RICHFIELD, IDAHO

LOCATION. In NE. M SE. M sec. 18, T. 2 S., R. 18 E., Blaine County, 18 

miles northwest of Richfield, Lincoln County.

DRAINAGE AREA. 1,500 square miles (furnished by Idaho Irrigation Co.).

RECORDS AVAILABLE. February 3, 1909, to September 30, 1925. Prior to 

April 4, 1909, gage-height record only is available. Practically no storage 

prior to July 14, 1909, when first stop logs were placed in tunnel entrance.

GAGE. All readings made by measuring with a weighted steel tape from tower 

on east side of dam. Below elevation, 4,855 feet readings obtained by measuring from a well-defined offset in walls of tower; when stages are above 

that elevation measurements are made in a 5^i-inch well casing which 

serves as a stilling well, bolted to face of tower. Readings made by attendants at dam. Observations are referred to an assumed datum which is 

about 137 feet lower than sea level. (To change readings to sea-level 

datum about 137 feet should be subtracted.)

EXTREMES OF CONTENTS. Maximum stage recorded during year, 4,935.07 feet 

May 20, 21, and 31 (contents, 191,778 acre-feet); minimum stage, 4,824.10 

feet October 10 (contents, 207 acre-feet). Lower stage may have occurred 

October 1-6 when gage was not read.

1909-1925: Maximum stage recorded, 4,935.08 feet June 18, 1922 (contents, 191,818 acre-feet); reservoir drained December 24-26 and 29, 1909, 

August 25, September 11-16, 19, 21, 22, December 14-18 and 21-31, 1919, 

January 1-6, August 9, 10, and 20-23, 1920, August 29 to September 30, 

1924.

COOPERATION. Gage-height record furnished by water master for Big Wood and 

Little Wood Rivers.

Stored water from this reservoir is used for irrigation on about 69,000 acres 

of land, under Carey Act project of the Big Wood Canal Co. (Ltd.), operated 

prior to 1921 by Idaho Irrigation Co. The reservoir is formed by a gravity 

earth and rock fill dam several hundred feet long at crest and 127 feet above 

bottom of outlet gates. Concrete lip spillway 400 feet long is provided, crest 

of which is 15 feet below top of dam. Elevation of bottom of outlet gates corresponds to 4,818.5 feet on gage which is about 3 feet lower than the actual stage 

of zero storage. At times, however, the stage may fall below 4,821.5 feet, 

depending upon the amount of normal flow passing through reservoir. Elevation of concrete lip spillway crest corresponds to 4,930 feet on gage. Use of a 

system of flashboards extends the actual elevation of spillway crest to 4,935 

feet with respect to gage datum, at which stage the capacity of the reservoir is 

about 191,000 acre-feet, as determined by latest capacity table, based upon 

inflow and outflow records, about 4,000 acres being submerged at this stage.

BIG WOOD RIVEK BELOW MAGIC DAM, NEAR RICHFIELD, IDAHO

LOCATION. In sec. 18, T. 2 S., R. 18 E., Blaine County, half a mile below Magic 

Dam and 18 miles northwest of Richfield, Lincoln County. No tributaries^ 

between dam and station.

DBAINAGE ABEA. Not measured.

RECORDS AVAILABLE. April 19, 1911, to September 30, 1925.

GAGE. Gurley water-stage recorder on right bank; installed April 20, 1916;.: 

inspected by Ed. Dayton.

DISCHABGE MEASUREMENTS. Made from cable at gage or by wading.

CHANNEL AND CONTBOL. Bed and control composed of clean coarse gravel and, 

small boulders; somewhat shifting. Banks high and brushy.

EXTBEMES OF DISCHARGE. Maximum stage during year from water-stage^ 

recorder, 6.81 feet at 8 p. m. May 20 (discharge, 2,510 second-feet); minimum 

discharge, 4.1 second-feet (by measurement) November 30.

1911-1925: Maximum stage recorded, 9.2 feet May 18, 1911 (discharge. 

5,070 second-feet); no flow reported February 3, 1915.

ICE. Stage-discharge relation seldom affected by ice.

DIVERSIONS. No diversions are made by Big Wood Canal Co. above this station, 

but numerous ranch diversions are made in the upper drainage area, thelargest quantity of water probably being used in the district below Hailey. 

Flood waters are stored in Magic Reservoir just above station and the first 

diversion by the company is Richfield Canal, 2 miles below.

REGULATION. Flow past station completely regulated by gates in outlet tunnel! 

at Magic Dam.-
TRIBUTARY BASINS 143

ACCURACY. Stage-discharge relation changed during high water June 20 to 

August,4. Standard rating curve well defined. Operation of water-^tage 

recorder satisfactory. Daily discharge ascertained by applying to rating 

table mean daily gage height obtained by inspection of recorder graph or 

for days of considerable fluctuation in stage by averaging discharge for 

intervals of the day. Shifting-control method used June 20 to August 4. 

Records excellent except for estimated periods, for which they are good.

COOPERATION. Gage-height record and several discharge measurements furnished by water master for Big Wood and Little Wood Rivers.

Discharge measurements of Big Wood River below Magic Dam, near Richfield, 

Idaho, during the year ending September 80, 1925

Feb. 11, Feb. 13 to Mar. 13, and Sept. 15 based on gate changes, records and information furnished by water 

master for Big Wood and Little Wood Rivers; winter flow consists only of leakage through gates at Magic 

Dam. Discharge interpolated Nov. 13-14 and Dee. 18-19. Braced figures show mean discharge for periods 

indicated.

BIG WOOD RIVER ABOVE NORTH GO ODIN G CANAL. NEAR SHOSHONE, IDAHO

LOCATION. In sec. 10, T. 4 S., R. 18 E., 1 mile above heading of North Gooding

Canal, 13 miles below Magic Dam, and 14 miles northeast of Shoshone,

Lincoln County.

DRAINAGE AREA. Not measured. 

RECORDS AVAILABLE. April 21, 1921, to August 22, 1925, when station was

temporarily discontinued, because Lincoln Canal will carry flow of river

around gage. Records will be resumed during future irrigation seasons if

water passes this point. 

GAGE. Vertical staff on right bank; read by J. H. Gilmore. Datum raised 5.0

feet April 16, 1923.

DISCHARGE MEASUREMENTS. Made from cable 300 feet below gage or by wading. 

CHANNEL AND CONTROL. Bed composed of lava rock partly covered with gravel.

Control formed by lava rock riffle 100 feet below gage; fairly permanent.

One channel at all stages. Point of zero flow occurs at a gage height of

approximately 0.5 foot. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.78 feet at

6 a. m. May 22 (discharge, 1,510 second-feet); channel reported dry most

of nonirrigation season.

1921-1925: Maximum stage recorded, 12.79 feet (old datum) June 13,

1921 (discharge, 3,330 second-feet); channel practically dry except during

irrigation seasons each year. 

ICE. Channel practically dry during winter. 

DIVERSIONS. Numerous diversions for irrigation made above and below station.

Richfield and Lincoln Canals are main diversions between station and Magic

Dam. Lincoln Canal, completed in spring of 1925, diverts water around

station on right bank to conserve channel losses in the natural stream bed

throughout an 8-mile stretch of river. 

REGULATION. Flow regulated by operation of head gates at Magic Dam 13

miles above. 

ACCURACY. Stage-discharge relation practically permanent. Rating curve well

defined between 100 and 1,500 second-feet. Gage read to hundredths twice

daily. Daily discharge ascertained by applying mean daily gage height to

rating table, except as indicated in footnote to table of daily discharge.

Records good. 

COOPERATION. Gage-height record and two discharge measurements furnished

by water master for Big Wood and Little Wood Rivers.

BIG WOOD RIVER BELOW NORTH GOODING CANAL, NEAR SHOSHONE, IDAHO

LOCATION. In sec. 15, T. 4 S., R. 18 E., 300 yards below heading of North 

Gooding Canal, 13 miles northeast of Shoshone, Lincoln'County, and 14 

miles below Magic Dam.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. January 1, 1911, to September 30, 1925.

GAGE. Gurley 7-day water-stage recorder on right bank; installed July 5,. 

1920; inspected by water master for Big Wood and Little Wood Rivers and 

his assistants. Prior to July 8, 1918, datum was about 6 feet lower than 

present datum.

DISCHARGE MEASUREMENTS. Made from cable 100 feet below gage or by wading.
146 SURFACE WATER SUPPLY, 1925, PART XII B

CHANNEL AND CONTROL. Bed composed of lava rock; practically permanent, 

rough. At extremely high stages water overflowed above North Gooding 

diversion dam into secondary channel to left of gage. Control fairly well 

denned.

EXTREMES OP DISCHARGE. Maximum measured discharge, 1,020 second-feet 

May 21; channel reported dry except during period of recorded flow.

1911-1925: Maximum stage recorded, 15.0 feet (old datum) May 18, 

1911 (discharge, 3,180 second-feet); no flow occurred during several different 

periods since establishment of station.

ICE. Channel reported dry during winter.

DIVERSIONS. Station is below all diversions of Big Wood Canal Co. North 

Gooding and Richfield Canals divert between station and Magic Dam. 

Lincoln Canal (designed to carry about 700 second-feet), construction of 

which was completed in spring of 1925, heads 7 miles below Magic Dam 

and enters North Gooding Canal one-fourth mile above station. It diverts 

water on right bank of Big Wood River for purpose of conserving loss in 

natural channel throughout this stretch of river.

REGULATION. Flow past station is regulated by gates at Magic Dam and head 

gates of North Gooding and Richfield Canals.

ACCURACY. Stage-discharge relation practically permanent. Rating curve 

well defined. Water-stage recorder operated satisfactorily except for short 

periods when clock caused trouble. Staff readings made twice daily were 

used May 3-4, 25-31, June 1-7, July 28-31, and August 1-2. Daily discharge obtained by applying mean daily gage height to rating table. During 

periods water-stage recorder was operated, mean daily gage height determined by inspection of recorder graph except for days of considerable fluctuation when mean discharges were obtained for intervals of the day. Records 

good.

COOPERATION. Gage-height record and five discharge measurements furnished 

by water master for Big Wood and Little Wood Rivers.

BIG WOOD RIVER AT GOODING, IDAHO

LOCATION. In sec. 29, T. 5 S., R. 15 E., Gooding County, 30 feet below highway 

bridge and half a mile north of Gooding station on Oregon Short Line Railroad.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 1,1921, to September 30,1925. From June 2,1896, 

to October 31,1899, at approximately same site but known as "Malad River 

at Toponis."

GAGE. Gurley water-stage recorder on left bank; inspected by James Devaney.

DISCHARGE MEASUREMENTS. Made from cable 600 feet below gage or by wading.

CHANNEL AND CONTROL. Bed composed of lava rock overlain with gravel. Control formed by lava-rock riffle 300 feet below gage; growth of willows and 

weeds affects stage-discharge relation occasionally. One channel at all 

stages. Zero flow would occur at gage height of 0.80 foot ±0.10 foot, as 

determined April 27, 1923.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage 

recorder, 3.63 feet at 4 p. m. May 22 (discharge, 735 second-feet); channel 

reported dry April 8 to noon April 26, 8 a. m. August 22 to 5.30 a. m. August 

24, September 18-30, and at other times during period of no record.

1921-1925: Maximum stage recorded, 5.80 feet May 7, 1922 (discharge, 

2,340 second-feet); channel dry for long periods each year.

ICE. Channel generally dry during winter.

DIVERSIONS. Numerous diversions for irrigation above and below station.

REGULATION. Flow regulated by operation of head gates at Magic Dam and 

by diversions above gage.

ACCURACY. Stage-discharge relation changed May 8-17 and May 26 to August 

16, owing to fouled condition of control. Standard rating curve well defined. 

Operation of water-stage recorder satisfactory. Daily dischage ascertained 

by applying to rating table mean daily gage height determined by inspection of recorder graph or for days of considerable fluctuation by averaging discharges for intervals of a day. Shifting-control method used 

May 8-17 and May 26 to August 16. Record fair.

COOPERATION. Gage-height record and' several discharge measurements furnished by water master for Big Wood and Little Wood Rivers.

BIG WOOD SLOUGH AT HAHEY, IDAHO

LOCATION. In sec. 9, T. 2 N., R. 18 E., at highway bridge, one-eighth mile northeast of steel highway bridge across Big Wood River, and one-eighth mile 

southwest of Hailey, Blaine County.

RECORDS AVAILABLE. June 11, 1915, to September 30, 1925.

GAGE. Vertical staff in concrete stilling well on left bank 3 feet below highway 

bridge; installed August 3, 1923; read by R. F. Bowman.

DISCHARGE MEASUREMENTS. Made from footbridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel. Banks covered 

with brush and may be overflowed. One channel at all stages. Control 

formed by a wood stave water pipe, laid in bed of stream about 15 feet 

below gage; changes slightly.

EXTREMES OP DISCHARGE. Maximum discharge during year, 262 second-feet 

occurred at 5.50 p. m. August 14 (gage height, 1.90 feet); minimum stage, 

1.36 feet March 16 and 17 (discharge, 59 second-feet).

1915-1925: Maximum stage recorded, 3.00 feet June 6, 1921 (discharge, 

419 second-feet; minimum discharge, 0.9 second-foot March 21-24, 1919.

ICE. Stage-discharge relation seldom affected by ice.

DIVERSIONS. None.

REGULATION. The amount of water passing gage is affected by load at power 

plant half a mile upstream, and there is considerable fluctuation. The 

main river station is affected inversely by any such regulation, so that the 

accuracy of the summation of the two records is presumably affected only 

slightly by this factor.

ACCURACY. Stage-discharge relation changed frequently during year by accumulation on and removal of drift from control. Standard rating curve 

fairly well defined. Gage read to hundredths once daily October to March 

and twice daily April to August. Daily discharge ascertained by applying 

daily gage height or mean daily gage height to rating table. Discharge 

estimated on account of ice effect December 18 to January 18. Records 

fair.

COOPERATION. Five discharge measurements furnished by water master for 

Big Wood and Little Wood Rivers.

Big Wood Slough is a natural channel of Big Wood River that is utilized also 

as a tailrace for Hailey power plant. Record from this station represents & part 

of the natural flow of Big Wood River and taken in conjunction with the record 

at the near-by station on the main river (see p. 136), will show the entire flow 

of the river at this point. For record of combined flow of Big Wood River and 

Big Wood Slough see page 139.

and silt. One channel at all stages. Control formed by Cippoletti weir set 

in concrete, located immediately below gage; weir crest is 17.64 feet in 

length. Zero of gage set to agree with average elevation of weir crest.

EXTREMES OP DISCHARGE. Maximum stage recorded during period, 1.35 feet 

July 19 and 20 (discharge, 96 second-feet); reported dry May 21 and practically dry during nonirrigation season.

1919-1920; 1923-1925: Maximum stage recorded, 1.46 feet August 3-5, 

1923 (discharge, 108 second-feet); practically no flow during nonirrigation 

seasons since completion of reservoir above gage in 1920.

ICE. Stage-discharge relation probably affected by ice; practically no flow in 

winter.

DIVERSIONS. None between station and dam.

REGULATION. Flow completely regulated by operation of gates in dam above.

ACCURACY. Stage-discharge relation changed slightly August 14, caused by 

leakage under weir. Standard rating curve well defined; parallel curve used 

May 7 to September 30. Gage read to hundredths once daily. Daily 

discharge determined by applying daily gage height to rating table. Discharge interpolated June 5. Records good.

COOPERATION. Gage-height record furnished by water master for Fish Creek.

The following discharge measurements were made:

July 10, 1925: Gage height, 0.58 foot; discharge, 26.8 second-feet.

August 27, 1925: Gage height, 0.63 foot; discharge, 31.8 second-feet.

channel at all stages. Control formed by 12-foot Cippoletti weir set in 

concrete. Zero of gage corresponds to average elevation of weir crest.

EXTREMES OP DISCHARGE. Maximum stage occurred during period of estimated 

discharge, May 8-23; minimum discharge, 0.3 second-foot several days 

after July 16. Probably not actual extremes.

1920-1925: Maximum stage recorded, 0.93 foot at 9 p. m. April 22, 1922 

(discharge, 42.8 second-feet); minimum discharge, 0.1 second-foot at 8.30 

p. m. August 8, 1920, and several days in 1924 after June 26. Probably 

not actual extremes.

ICE. Stage-discharge relation affected by ice; records discontinued during 

winter.

DIVERSIONS. One small diversion above gage.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent. Rating curve used based on 

standard weir formula for 12-foot Cippoletti weir which has been fairly well 

substantiated by several discharge measurements made 1923-1925. Depth 

of water over weir crest measured to hundredths about twice a week. Daily 

discharge determined by applying daily gage height to rating table and 

interpolating for days when gage was not read. Records poor May 8-23; 

otherwise fair.

COOPERATION. Gage-height record furnished by water master for Fish Creek.

The following discharge measurements were made:

May 24, 1925: Gage height, 0.16 foot; discharge, 2.2 second-feet.

July 10, 1925: Gage height, 0.05 foot; discharge, 0.4 second-foot.

LOCATION. In sec. 35, T. 1 S., R. 7 E., 8 miles southwest of Bennett, Elmore

County, and 17 miles northeast of Mountain Home. 

DKAINAGE AKEA. Not measured.

RECORDS AVAILABLE. April 3, 1924, to August 12, 1925. 

GAGE. Readings obtained by measuring with steel tape from top of upstream

corner of masonry gate tower on southeast end of dam; read by J. N. Goset.

Elevations referred to datum of Mountain Home Cooperative Irrigation Co.
168 SURFACE WATER SUPPLY, 1925, PART XII B

EXTREMES OF STAGE. Maximuir stage during year from high-water marks in

spillway, 4,455.30 feet about April 20; reservoir practically empty after

August 12.

1924-1925: Maximum stage recorded, about April 20, 1925; reservoir

empty in fall of each year. 

COOPERATION. Occasional readings furnished by Mountain Home Cooperative

Irrigation Co.

This reservoir is used partly as a storage unit and partly as an equalizing basin 

for natural flow of Long Tom Creek and for storage water released from Little 

Camas Reservoir which is carried several miles through an open canal and series 

of tunnels into Long Tom Basin. From Long Tom Reservoir water is released 

and flows through Long Tom and Canyon Creeks to the head of Mountain Home 

feeder canal and is used for irrigation on about 5,000 acres of land near Mountain 

Home.

The reservoir is formed by a gravity earth dam with a crest of 400 feet. Crest 

is 56 feet above bottom of outlet tunnel and 6 feet above crest of spillway. Elevation of bottom of outlet tunnel corresponds to 4,404.15 feet referred to recorded 

reservoir stages, at which stage the available storage is practically zero. Elevation of crest of spillway corresponds to 4,453.87 feet, at which stage the capacity 

of the reservoir is about 4,040 acre-feet, about 153 acres of land being submerged

OWYHEE RIVER NEAR GOLD CREEK, NEV.

LOCATION. In W. }/% sec. 24, T. 44 N., R. 54 E., one-eighth mile below Wild 

Horse dam site, 9 miles west of Gold Creek, Elko County, and 65 miles 

north of Elko.

DRAINAGE AREA. 209 square miles (measured on map compiled by irrigation 

service of United States Office of Indian Affairs).

RECORDS AVAILABLE. March 26, 1916, to September 30, 1925.

GAGE. Stevens continuous water-stage recorder on left bank; inspected by 

Emery Johnson.

DISCHARGE MEASUREMENTS. Made from cable at gage or by wading.

CHANNEL AND CONTROL. Bed composed of rocks and loose sand. Left bank 

high and rocky; right bank is overflowed at extremely high stages. One 

channel at all stages. Dense growth of willows along banks. Control is 

gravel riffle in each of two channels where stream is divided by small island 

500 feet below gage; subject to change by work of beavers.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 6.73 feet at 

5 a. m. April 12 (discharge, 860 second-feet); minimum discharge, about 1 

second-foot August 20-23 (stage affected by backwater from beaver dam).

1916-1925: Maximum stage 10.11 feet at 2 a. m. May 5, 1922 (discharge 

by extending rating curve, 1,810 second-feet); minimum discharge probably 

less than 1 second-foot in August, 1918.

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Wild hay meadows above station practically only land irrigated.

ACCURACY. Stage-discharge relation changed during winter; affected by ice 

greater part of winter and by beaver dam July 16 to September 30. Rating 

curves fairly well defined below 250 second-feet and extended above. Operation of water-stage recorder satisfactory October 1 to November 9, April 1 

to June 21, July 8 to August 28, and September 15-30. Discharge during 

winter, for periods when affected by beaver dam, and for periods when no 

gage heights were taken, interpolated or estimated from observer's notes 

and by comparison with flow of Owyhee River at station near Owyhee. 

Records good, April to June; fair, October and November; and probably 

poor for remainder of year.

The following discharge measurements were made: 

May 6, 1925: Gage height, 3.52 feet; discharge, 211 second-feet. 

May 25, 1925: Gage height, 2.50 feet; discharge, 67.5 second-feet. 

June 18, 1925: Gage height, 1.85 feet; discharge, 19.7 second-feet.

LOCATION. In sec. 21, T. 46 N., R. 53 E., 40 feet above mouth of Jones Brook,.

half a mile above J. P. Jones ranch, 4 miles below Mountain City, and 8-

miles southeast of Owyhee, Elko County.

DRAINAGE AREA. 380 square miles (measured on Forest Service map). 

RECORDS AVAILABLE. November 29, 1913, to September 30, 1925. 

GAGE. Stevens continuous water-stage recorder on right bank; inspected by

P. W. Davidson. 

DISCHARGE MEASUREMENTS. Made from cable 125 feet above gage or by wading..
TRIBUTARY BASINS 175

CHANNEL AND CONTROL. Bed consists of ledge rock and boulders filled in with 

sand and gravel; permanent, except for slight changes at very low stages 

One channel at all stages. Banks covered with willows and brush; subject 

to overflow. At low stages a riffle just below gage forms control; shifts 

occasionally. At high stages a secondary control becomes effective; 

practically permanent.

EXTREMES OP DISCHARGE. Maximum stage during year from water-stage 

recorder, 8.97 feet at 9.30 p. m. April 12 (discharge, 1,230 second-feet). 

Minimum discharge, 3 second-feet August 21-23.

1914-1925: Maximum discharge, 2,600 second-feet May 5, 1922; minimum 

discharge less than 1 second-foot August 5 and 16, 1924.

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. A number of ranches above station divert water from main 

stream and tributaries for irrigation mainly of hay meadows.

REGULATION. None.

ACCURACY. Stage-discharge relation for low water changed during period of 

ice effect December 19 to January 31. Rating curves well defined. Operation of water-stage recorder satisfactory except April 21-26. Daily discharge ascertained by applying mean daily gage height to rating table. 

Discharge estimated for periods when no gage heights were obtained and 

during ice-affected period, by comparison with Gold Creek record and 

observer's notes at Mountain City. Records good.

The following discharge measurements were made: 

May 7, 1925: Gage height, 5.77 feet; discharge, 598 second-feet.2 

May 26, 1925: Gage height, 3.65 feet; discharge, 214 second-feet. 

June 19, 1925: Gage height, 2.52 feet; discharge, 62.7 second-feet.

LOCATION. In sec. 2, T. 21 S., R. 46 E., at county bridge, 1J^ miles southwest 

of Owyhee, Malheur County, 3 miles above mouth of river, and 10 miles 

southwest of Nyssa.

DRAINAGE AKEA. About 11,100 square miles. Watershed poorly defined on 

available maps.

RECORDS AVAILABLE. March 26, 1890, to December 31, 1893; January 1, 1895, 

to October 3, 1896; August 28, 1903, to September 30, 1916; May 17 to 

October 9, 1920; March 8, 1921, to September 30, 1925.

GAGE. Chain gage on upstream side of highway bridge; read by Walter Pinkston 

or Mrs. S. J. Watson.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of gravel; may shift during high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.5 feet February 7 (discharge, 7,100 second-feet); minimum stage, 1.60 feet July 31, 

August 1 and 4-11 (discharge, 2 second-feet).

1890-1893; 1895-96; 1903-1916; 1920-1925: Maximum stage recorded, 

12.9 feet March 2, 1910 (discharge, 23,200 second-feet). No flow July 7,19, 

and August 14-16, 1924.

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Owyee Canal, the principal diversion immediately above the station, heads about 6 miles above gage. This canal diverts practically entire 

natural low-water flow of river. (See p. 179.)

REGULATION. Variation in the flow may be caused by manipulation of gates at 

head of Owyee Canal.

OWYHEE CANAL NEAR OWYHEE, QREG.

LOCATION. In NE. ]£ sec. 12, T. 21 S., R. 45 E., 1 mile below head of canal, 6 

miles southwest of Owyhee, Malheur County, and 15 miles southwest of

RECORDS AVAILABLE. October 5, 1911, to September 30, 1916; and irrigation 

seasons 1904, 1905, and 1920-1925.

GAGE. Stevens 8-day water-stage recorder at right end of bridge; read by W. 

H. Beam.

DISCHARGE MEASUREMENTS. Made from footbridge at gage.

CHANNEL AND CONTROL. Bed clean and smooth. Control not well defined but 

fairly permanent except as affected by check 1 mile downstream.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.24 feet at 

noon May 12 and 17 (discharge, 326 second-feet); canal dry at times.

1904-5; 1911-1916; 1920-1925: Maximum stage recorded, 4.3 feet May 

17, 1921, and May 10-11, 1922 (discharge, 333 second-feet); canal dry at 

various times each year.

ICE. No record during winter.

DIVERSIONS. Station above all diversions from canal; surplus water is returned 

to Owyhee River through two wasteways between gage and station on 

river near Owyhee.

REGULATION. Abrupt changes of stage due to manipulation of head gates not 

to be expected, as water is kept at nearly constant stage.

ACCURACY. Stage-discharge relation permanent except as affected by varying 

number of flashboards on check 1 mile below gage June 11 to August 31. 

Standard rating curve well denned. Correction applied for backwater effect 

somewhat uncertain. Water-stage recorder operated satisfactorily April 

1 to August 2, except as indicated in footnote to daily-discharge table; staff 

gage read to hundredths once a day August 2-29. Daily discharge ascertained by applying daily gage height to rating table. Records good April 

1 to June 30 and fair July 1 to August 31.

COOPERATION. Record furnished by State engineer of Oregon.

Owyhee Canal diverts water from Owyhee River in sec. 18, T. 21 S., R. 46 E. 

In 1920 it supplied water for irrigation to 13,397 acres of land near Owyhee, 

Nyssa, and Ontario.

The following discharge measurements were made:

April 23, 1925: Gage height, 2.95 feet; discharge, 191 second-feet.

(contents, 286,100 acre-feet); natural flow passing through reservoir, September 13-17, September 20 to October 1, 1919, September 13 to October 10, 

1920, September 19 to October 22,1922, and August 19 to October 15,1924.

COOPERATION. Gage-height record and table of storage capacity furnished by 

United States Bureau of Reclamation.

Stored water from this reservoir is used for irrigation of land in Boise Valley. 

The reservoir is formed by a concrete dam, gravity section, 348.5 feet high and 

1,100 feet long at crest. Base of dam is 223 feet thick and thinnest point near top 

is 15.5 feet thick. A 16-foot roadway is carried across on top of dam. A lip 

spillway at north end of dam has a carrying capacity of 40,000 second-feet. 

Elevation of spillway crest referred to gage datum is 3,205 feet, the capacity of

NOTE. Natural flow passing through reservoir Oct. 1-15. Contents estimated Nov. 19, 23-24, Dec. 

18-24, Jan. 1-2, 4, and 7, based on inflow and outflow records as furnished by United States Bureau of 

Reclamation; interpolated because of missing gage heights Aug. 15, 25, Sept. 4 and 20.

BOISE RIVER AT DOW1ING RANCH, NEAR ARROWROCK, IDAHO

LOCATION. In sec. 15, T. 3 N., R. 4 E., at Dowling ranch, Elmore County, 

.three-fourths mile above Moore Creek, 2 miles below Highland power dam, 

and 4 miles below Arrowrock.

DRAINAGE AREA. 2,230 square miles (measured on topographic maps).

RECORDS AVAILABLE. March 12, 1911, to September 30, 1925.

GAGE. Friez water-stage recorder on left bank; installed March 19, 1915; inspected by J. N. Davis.

DISCHARGE MEASUREMENTS. Made from cable 50 feet below gage or by wading.

CHANNEL AND CONTROL. Bed composed of gravel and boulders. One channel 

at all stages. Control shifts slightly. Stage of zero flow as determined 

March 28, 1924, at gage height 0.30 foot ±0.2 foot.

EXTREMES OP DISCHARGE. Maximum stage during year from water-stage recorder, 8.72 feet at 10 a. m. May 20 (discharge, 14,300 second-feet); minimum 

discharge estimated at 5 second-feet November 2-10, December 21 to January 6, and March 26-29.

1911-1925: Maximum stage recorded, 9.27 feet from noon to 4 p. m. June 

12, 1921 (discharge, 16,500 second-feet); minimum discharge, estimated at 

5 second-feet November 2-10, December 21 to January 6, and March 26-29, 

1925.
184 SURFACE WATER SUPPLY, 1925, PART XII B

ICE. Stage-discharge relation affected by ice during severe winters.

DIVERSIONS. No important diversions above station. New York Canal of 

Boise project, United States Bureau of Reclamation, diverts 10 miles below 

and has a maximum capacity of 2,500 second-feet. Several smaller canals, 

total capacity of about 2,900 second-feet, divert below New York Canal.

REGULATION. Since February 21, 1915, flow has been regulated at Arrowrock 

Dam, 4 miles upstream, which has storage capacity of about 280,000 acrefeet. Water is stored during winter and spring and released during irrigation 

season.

ACCURACY. Stage-discharge relation changed slightly November 11, 21, February 26 to March 8 and April 4-20; affected by ice January 7-22. Two 

standard rating curves used; the first, applicable October 1-31, well denned, 

below 3,500 second-feet; second, applicable March 9 to April 3 and April 21 

to May 29, well defined below 13,000 second-feet; curves parallel to second 

curve used November 12-20, November 22 to February 25, May 30 toSeptember 30. Operation of water-stage recorder satisfactory except for 

short period when water was below intake pipe of well. Daily discharge 

ascertained by applying to rating table mean daily gage height determined 

by inspection of recorder graph. Records good except for estimated periods, 

for which they are fair.

COOPERATION. Several discharge measurements furnished by United States; 

Bureau of Reclamation and water master for Boise River.

MOORE CREEK NEAR ARROWROCK, IDAHO

LOCATION. In sec. 21, T. 3 N., R. 4 E., at highway bridge on Boise-Arrowrock 

road, a quarter of a mite above mouth, and 3 miles southwest of Arrowrock, 

Boise County.

DRAINAGE AREA. 426 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 1, 1914, to September 30, 1925 (discharge measurements only prior to December 1, 1915).

GAGE. Vertical staff on right bank, 15 feet above highway bridge; read by Oliver 

Call.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of boulders, cobbles, and sand. Control 

shifts frequently owing to deposition of sand at low stages and scouring out 

at high stages. Stream usually carries much sand and silt as a result of 

placer operations in Boise Basin. One channel at all stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 3.50 feet April 

12 (discharge, 2,280 second-feet); minimum discharge, 24 second-feet 

October 2.

1915-1925: Maximum stage recorded, 6.3 feet April 11, 1916 (discharge, 

3,140 second-feet); minimum stage, 0.09 foot August 13-15, 17, and 18, 

1924 (discharge, 7.9 second-feet).

ICE. Stage-discharge relation not seriously affected by ice.

DIVERSIONS. No important diversions above station.

RE GUL ATI o N. None.

ACCURACY. Stage-discharge relation not permanent; affected by ice December 

18-29. Two standard well-defined rating curves. Gage read to hundredths 

once daily; rough water at high stages makes it difficult to read gage with 

refinement. Daily discharge determined by applying gage height to rating 

table. Records of daily discharge subject to error; records of monthly 

discharge, good.

COOPERATION. Several discharge measurements made by employees of United 

States Bureau of Reclamation and water master for Boise River; gage-height 

record furnished by the former.

MAIHEUE RIVEE BELOW WARMSPRINGS RESERVOIR, NEAR RIVERSIDE, OREG.

LOCATION. In SW. % sec. 17, T. 23 S., R. 37 E., 1 mile below Warmsprings 

Dam, 3 miles above mouth of South Fork, and 4 miles northwest of Riverside, Malheur County.

DBAINAGE AREA. About 1,100 square miles.

RECORDS AVAILABLE. December 9, 1914, to July 4, 1917; March 18, 1919, to 

September 30, 1925. From January 3, 1906, to March 31, 1907, and December 15, 1908, to May 25, 1910, records were obtained at a station at 

Riverside 4 miles below,

GAGE. Vertical staff on left bank used since April 28, 1920; read by U. S. Yost.

DISCHAHGE MEASUREMENTS. Made from highway bridge one-fourth mile below 

dam or by wading.

CHANNEL AND CONTHOL. Concrete control 200 feet below gage. There is some 

disintegration of concrete during winter because of poor quality. Above a 

medium stage concrete control is submerged and contraction and riffle 200 

feet farther downstream acts as control for gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.72 feet at 

time of measurement on April 27 (discharge, 900 second-feet); seepage 

amounted to 1 second-foot when gates to reservoir were closed October 

1 to April 23 and May 6-8.
TRIBUTARY BASINS 197

1906-1925: Maximum discharge recorded, 5,490 second-feet March 2, 

1910; minimum discharge recorded prior to construction of dam, practically 

no flow during August, 1910; determined by subtracting discharge of South 

Fork from discharge of main river below South Fork. Minimum discharge 

since construction of dam somewhat less than 1 second-foot when gates 

are closed; stream dry August 1 to September 16, 1919, while dam was 

being constructed.

ICE. No water released from dam during winter.

DIVEESIONS. A large area of bottom land is irrigated with flood water above 

station.

REGULATION. Flow past station entirely controlled by operation of gates in 

Warmsprings Dam beginning November, 1919.

ACCURACY. Stage-discharge relation changed during winter. Rating curves 

fairly well defined. Staff gage read to hundredths once a day and time noted 

when change was made in gate openings at dam. Daily discharge ascertained by applying daily gage height or mean daily gage height to rating 

table. Records good.

MALHEUR RIVER NEAR HOPE, OREG.

LOCATION. In SW. M sec. 5, T. 19 S., R. 43 E., half a mile above intake of 

Vines Canal and railroad bridge, 15 miles west of Vale, and 6J^ miles west 

of Hope, Malheur County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 30 to October 26, 1919; May 5 to September 30, 

1920; fragmentary record during 1921 and 1922; October 1, 1922, to September 30, 1925. Station maintained half a mile below Vines Canal, March 

22 to September 30, 1914.

GAGE. Stevens continuous water-stage recorder- on left bank; inspected by 

C. L. Bachelder and H. G. Kennard.

DISCHARGE MEASUREMENTS. Made from cable at gage or by wading.

CHANNEL AND CONTROL. Bed composed of sand, gravel, and boulders; subject 

to shift at high stages. One channel at all stages.

EXTREMES OF DISCHARGE. Maximum discharge from water-stage recorder, 

about 8,100 second-feet from 1 to 2 p. m. February 5; minimum discharge, 

estimated 50 second-feet December 26 , and January 23.

1919-1925: Maximum discharge recorded, that of J.925; minimum stage, 

0.02 foot from,5 to 9 p. m. September 2, 1919 (discharge, 3.5 second-feet).

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Several email canals divert water above station.

REGULATION. Flow controlled to a large extent by Warmsprings Dam 60 miles 

above.

ACCURACY. Stage-discharge relation practically permanent; affected by ice 

probably December 18 to January 29. Rating curve fairly well defined 

below 4,000 second-feet. Operation of water-rgtage recorder satisfactory 

except for periods indicated in footnote to daily-discharge table; recorded 

gage heights unreliable and not used after June 30, because of poor connection between well and river. Daily discharge ascertained by applying to 

rating table mean daily gage height determined from recorder graph by 

inspection. Discharge estimated for periods of no record. Records good 

except for estimated periods for which they are fair.

The following discharge measurements were made: 

January 23, 1925: Gage height, 2.80 feet; 5 discharge, 50 second-feet. 

April 7, 1925: Gage height, 2.08 feet; discharge, 389 second-feet. 

April 26, 1925: Gage height, 2.72 feet; discharge, 809 second-feet.

200 SURFACE WATER SUPPLY, 1925, PART XII B

GAGE. Stevens 8-day water-stage recorder on left bank inspected by James 

Minougham.

DISCHARGE MEASUREMENTS. Made from bridge 200 feet below gage or by 

wading.

CHANNEL AND CONTROL. Bed of sand and loose gravel. Just below gage is an 

artificial control of concrete. The crest is 2 feet above stream bed, 8 inches 

wide, inclined toward right where there is a low-water section 3 feet long 

and 6 inches lower than high-water crest. The cut-off walls at ends conform 

to slope of banks. Control was reconstructed in November, 1922, extending 

cut-off wall deeper into bed and banks and adding a concrete apron 6 feet 

long,

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage 

recorder, 2.63 feet from 10 to 11 a; ra. February 23 (discharge, 169 seeoadfeet). No flow August 1 to September 30.

1904-1906; 1910-1915; 1921-1925: Maximum discharge (computed from 

cross section and estimated velocities) 1,400 second-feet March 20, 1910. 

No flow at times.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Several small diversions above station irrigating a large area of 

meadowland; reservoir No. 3 just below. Eldorado ditch diverted no 

water into Willow Creek, 25 miles above gaging station, in 1925.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined. 

Operation of water-stage recorder satisfactory February 5 to August 2 

except for a few scattered days; staff gage read to hundredths once every 

other day except October 1 to February 4 and August 1 to September 30 

when there was little or no flow. Daily discharge ascertained by applying to 

rating table mean daily gage height obtained from recorder graph by inspection. Records good.

The following discharge measurements were made: 

March 19, 1925: Gage height, 1.20 feet; discharge, 21.2 second-feet. 

March 22, 1925: Gage height, 1.02 feet; discharge, 12.7 second-feet. 

April 25, 1925: Gage height, 1.35 feet; discharge, 29.6 second-feet.

September 30, 1925.

GAGE. Friez water-stage recorder on left bank; installed December 19, 1923; 

inspected by F. L. Williams, Datum unchanged since October 14, 1908.

DISCHARGE MEASUREMENTS. Made from cable half a mile below gage or by 

wading.

CHANNEL AND CONTROL. Bed and control composed of boulders, cobbles, and 

gravel; slightly shifting. One channel at all stages.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage 

recorder, 6.42 feet at 9 p. m. May 21 (discharge, 3,020 second-feet); minimum 

stage, 0.98 foot November 7 and 8 (discharge, 3.0 second-feet).

1908-1917; 1919-1925: Maximum stage recorded, 7.5 feet June 5, 1909 

(discharge, 4,250 second-feet); minimum discharge, 3 second-feet October 

21 and 22, 1911, November 10-26, 1919, and November 7 and 8, 1924.

ICE. Stage-discharge relation very seldom affected by ice, presumably because 

of proximity of station to Payette Lake.

DIVERSIONS. None above station.

REGULATION. Flow during irrigation season partly regulated by changing flashboards in dam installed in October and November, 1923, at outlet of Payette 

Lake a quarter of a mile above.

ACCURACY. Stage-discharge relation permanent except May 6-18, when tree on 

right end of control caused slight backwater effect; affected by ice December 

17 to January 10 and during early part of February. Rating curve well 

defined below 2,700 second-feet. Ice formation in gage well and lack of 

regular visits to gage caused frequent gaps in record; otherwise water-stage 

recorder operated satisfactorily. Daily discharge ascertained by applying 

to rating table daily gage height determined by inspection of recorder graph. 

Records good except for estimated periods for which they are fair.

COOPERATION. Gage-height record furnished by United States Forest Service.

River, and 2^ miles west of Lowman, Boise County.

DRAINAGE AREA. <217 square miles (measured on topographic maps).

RECORDS AVAILABLE. August 11, 1921, to September 30, 1925.

GAGE. Stevens continuous water-stage recorder on left bank; inspected by 

W. C. Taylor.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of gravel and boulders; rough. Banks 

fairly low but not subject to overflow; gradient steep. Control fairly well 

defined, wide, and not sensitive; practically permanent.

EXTREMES op DISCHARGE. Maximum stage during year from water-stage recorder, 4.14 feet at 1 a. m. May 20 (discharge, 2,500 second-feet); minimum 

stage, 1.14 feet October 20-23 (discharge, 78 second-feet). Actual minimum 

discharge probably occurred December 18 during ice-affected period immediately following unusual drop in temperature.

1921-1925: Maximum stage recorded, 4.53 feet at 3 a. m. May 26, 1922 

(discharge, 3,080 second-feet); minimum stage, 1.12 feet August 29, 1924 

(discharge, 75 second-feet). Lower discharge may have occurred about 

December 18, 1924, during extremely cold period.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during ice-affected period 

November 28 to January 31. Rating curves well defined. Operation of 

water-stage recorder satisfactory except during winter when its operation 

was discontinued on account of severe ice conditions. Staff gage read to 

hundredths about once a week during winter. Daily discharge ascertained 

by applying to rating table mean daily gage height determined from inspection of recorder graph or from staff gage readings. Records good except 

from December to March, for which they are poor.

228 SURFACE WATER SUPPLY, 1925, PART XII B

CRANE CREEK NEAR MIDVALE, IDAHO

LOCATION. In SE. y± sec. 19, T. 12 N., R. 2 W., 400 feet below Crane Creek 

Dam and 12 miles southeast of Midvale, Washington County. No tributaries between dam and station; Last Chance Creek enters three-fourths 

mile below.

DRAINAGE AREA. 269 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 30, 1910, to April 8, 1916; May 1, 1924, to 

September 30, 1925.

GAGE. Au water-stage recorder on right bank, installed May 2, 1924; inspected 

by Jesse W. Bain and Kenneth A. Hodge.

DISCHARGE MEASUREMENTS. Made from cable or by wading.

CHANNEL AND CONTROL. Bed composed of lava rocks and coarse gravel; very 

rough. One channel at all stages. Control formed by Cippoletti weir, 

crest of which is 20 feet long, installed in concrete, 25 feet below gage. 

Average elevation of weir crest corresponds to 0.02 foot on gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.42 feet 

February 7 to 7.30 a. m. February 13 (discharge, 674 second-feet); channel 

reported dry October 1 to noon February 4, 9 a. m. February 19 to 5 p. m. 

February 23, and 1 p. m. March 13 to noon March 16.

1910-1916; 1924-25: Maximum stage recorded, 8.9 feet December 3, 

1910 (discharge, 4,240 second-feet); no flow reported at various times when 

gates in dam are closed.

DIVERSIONS. No large diversions above gage. Flood waters are impounded in 

Crane Creek Reservoir and flow past gage therefore shows only the amount 

of water released through the dam and does not necessarily represent the 

actual flow of Crane Creek.

REGULATION. Flow completely regulated by gates at dam.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined 

below 300 second-feet. Gage read to hundredths twice daily February 4 to 

March 8, after which time water-stage recorder was satisfactorily operated. 

Daily discharge ascertained by applying mean daily gage height to rating 

table. Records good.

COOPERATION. Gage-height record furnished in part by Crane Creek Reservoir 

Administration Board.

TRIBUTARY BASINS

SALMON RIVER AT WHITEBIRD, IDAHO

243

LOCATION. In sec. 22, T. 28 N., R. 1 E., at highway bridge near Whitebird, 

Idaho County, just above Whitebird Creek and below all sizable tributaries.

DRAINAGE AREA. 13,600 square miles (measured on Land Office map, edition of 

1909).

EECOBDS AVAILABLE. August 18, 1910, to September 30, 1917; October 1, 1919, 

to September 30, 1925.

GAGE. Chain gage on handrail of highway bridge since September 14, 1920; read 

by R. E. Shuck and L. E. Shuck.

DISCHARGE MEASUREMENTS. Made from cable 900 feet below gage. Discharge 

measurements include flow of Whitebird Creek which enters Salmon River 

between gage and cable.

CHANNEL AND CONTROL. Channel straight for several hundred feet above and 

below gage; one channel at all stages. Banks not subject to overflow. 

Control composed of section of river channel and large boulder riffle threeeighths mile below; permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 16.4 feet May 

20-21 (discharge, 58,600 second-feet); minimum stage, 1.70 feet October 1 

(discharge, 3,020 second-feet). Lower flow may have occurred during 

severe cold period December 18-27, when stage-discharge relation was 

affected by ice. 

1910-1917; 1919-1925: Maximum stage recorded, 21.2 feet June 9, 1921 

(discharge, 88,800 second-feet); minimum stage on November 15, 1916, 

when water was below gage (estimated discharge, 2,500 second-feet).

Maximum stage determined from high-water marks, 27.5 feet June, 1894 

(discharge, 120,000 second-feet); estimated by extending rating curve.

ICE. Stage-discharge relation affected by ice during severe winters.

DIVERSIONS. Amount of water diverted for irrigation above station negligible.

REGULATION. None.

ACCURACY-. Stage-discharge relation permanent; affected by ice December 18-27. 

Rating curve well denned. Gage read to hundredths once daily. Daily 

discharge ascertained by applying daily gage height to rating table. Records 

good except for estimated period for which they are fair.

The following discharge measurements were made:

September 21, 1925^: Gage height, 3.01 feet; discharge, 5,060 second-feet.

September 21, 1925: Gage height, 3.02 feet; discharge, 5,070 second-feet.

LOCATION. In sec. 3, T. 10 N., R. 13 E., one-eighth mile above Valley Creek 

ranger station, one-fourth mile above confluence with Salmon River, threeeighths mile below Stanley, Custer County.

DRAINAGE AREA. 176 square miles (measured on topographic maps).

KECORDS AVAILABLE. December 21, 1910, to October 31, 1913; May 2, 1921, 

to September 30, 1925.

GAGE. Vertical staff on left bank installed May 2, 1921; read by W. L. Rose 

and R. E. Allan.

DISCHARGE MEASUREMENTS. Made from log bridge 300 feet upstream or by 

wading.

 CHANNEL AND CONTROL. Bed composed of gravel. Control well defined; 

practically permanent. Banks fairly low; left bank may be overflowed at 

extremely high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 2.96 feet at 

7 p. m. May 21 (discharge, 939 second-feet); minimum discharge estimated, 

55 second-feet December 18-27 during severe cold weather when stagedischarge relation was affected by ice.

1910-1913; 1921-1925: Maximum stage recorded, 4.4 feet May 29, 1921 

(discharge, 1,850 second-feet); minimum stage, 0.84 foot September 7, 1924 

(discharge, 41 second-feet).
TRIBUTARY BASINS 245

ICE. Stage-discharge relation affected by ice.

DIVEBSIONS. A few ranch diversions for irrigation above station.

REGULATION. None.

ACCTJEACT. Stage-discharge relation changed slightly during year. Two welldefined rating curves were used, the first applicable December 2-15 and the 

second applicable April 13 to September 30; curve parallel to latter used 

December 31 to April 6; shifting-control method used April 8-12. Gage 

read to hundredths twice daily April 20 to June 30, somewhat irregularly 

at other times. Daily discharge determined by applying daily or mean 

daily gage height to rating table or by interpolation for days when gage 

was not read. Records fair.

YANKEE FORK OF SALMON RIVER NEAR CIATTON, IDAHO

LOCATION. In sec. 20, T. 11 N., R. 15 E., at Sunbeam Dam, 350 feet above 

confluence with Salmon River, 3 miles west of Robinson Bar, 7 miles south 

of Bonanza, and 18 miles west of Clayton, Ouster County.

DRAINAGE AREA. 195 square miles (measured on topographic maps).

RECORDS AVAILABLE. May 3, 1921, to September 30, 1925.

GAGE. Vertical staff on right bank; read by Herman Meissner and Ferris Clark, 

Datum of gage lowered 0.40 foot June 26, 1924; lowered 0.65 foot September 

17, 1922. All gage heights prior to October 1, 1922, referred' to original 

datum; all gage readings from October 1, 1922, to September 30, 1924, 

reduced to datum established September 17, 1922; thereafter, all gage 

heights referred to datum established June 26, 1924.

DISCHARGE MEASUREMENTS. Made from highway bridge 250 feet below gage or 

by wading.

CHANNEL AND CONTROL. Bed composed of rock, boulders, and gravel. Control 

formed by rock and gravel riffle 50 feet below gage; well defined at low and 

medium stages. Although gradient is steep, control not well defined at 

high stages, due possibly to a slight backwater effect from Salmon River when 

in flood. One channel at all stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 4.75 feet 

May 29 (discharge, 1,760 second-feet); minimum discharge probably less 

than 25 second-feet during frozen period in December.

1921-1925: Maximum stage recorded, 5.24 feet at 8 p. m. June 12, 1921 

(discharge, 3,360 second-feet); minimum stage, 0.10 foot at 8 a. m. April 5, 

1924 (discharge, 22 second-feet). Lower flow may have occurred during 

ice-affected periods.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent after ice period. Rating curve 

well defined below 800 second-feet and extended above parallel to former 

curve. Gage read to half-tenths twice daily May 23 to July 23; once daily 

usually at other times. Daily discharge ascertained by applying daily or 

mean daily gage height to rating table. Records March to August good 

except those for estimated periods, which are fair; record poor for December and September.

COOPERATION. Gage-height record furnished by Lowe & von Brecht.

EAST FORK OF WALLOWA RIVER NEAR JOSEPH, OREG.

LOCATION. In SE. M sec. 29, T. 3 S., R. 45 E., one-fourth mile above mouth, 

1 mile below diversion dam of Enterprise Electric Co., 1 mile above Wallowa 

Lake, and 6 miles south of Joseph, Wallowa County.

DISCHARGE AREA. Not measured.

RECORDS AVAILABLE. July 27, 1924, to September 30, 1925.

GAGE. Vertical staff on right bank, 100 yards above bridge on road to power 

house; read by W. K. Wagner. Also auxiliary inclined gage at diversion 

dam 1 mile above.

DISCHARGE MEASUREMENTS. Made from bridge 100 yards below gage, from 

plank across stream, or by wading.

CHANNEL AND CONTROL. Channel curved above and below gage. Bed of coarse 

gravel and boulders; practically permanent. Steep gradient. Banks are not 

overflowed except in extremely high water. Control 10 feet below gage, 

well defined.

EXTREMES OF DISCHARGE. Maximum stage recorded during period July 27, 

1924, to September 30, 1925, 1.92 feet June 29 (discharge, 111 second-feet); 

minimum open-water stage, 0.72 foot March 31 and April 2 (discharge, 3.3 

second-feet). During the cold periods in December and January, flow was 

estimated to have reached a minimum of 3.0 second-feet.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. The penstock to power house of Enterprise Electric Co. diverts 

at dam 1 mile upstream.

REGULATION. Operation of power plants affects flow, maximum effect being, 

during low-water period; during extremely low-water periods in winter 

practically all flow at dam is diverted.

ACCURACY. Stage-discharge relation changed April 15; affected by leaves on 

control October 21-31 and by iee during winter. Rating curves fairly well 

defined. Staff gage read to hundredths twice daily except during winter when 

it was read once a day. Daily discharge ascertained by applying daily or 

mean daily gage height to rating table. Records good for open channel and 

fair during ice period.

Discharge over dam, length of crest of spillway being 21.6 feet, has been computed from weir tables for rectangular contracted weir, the application of which 

was checked by one discharge measurement, for the few days gage at dam was 

read. They indicate that inflow between dam and gaging station is 2 to 3 secondfeet at low water and averages 17 per cent of flow at gaging station when flow at 

station is more than 15 second-feet.

CHANNEL AND CONTROL. Control is a 5-foot Cippoletti weir made from 2-inch 

plank, beveled at top and set in concrete.

EXTREMES OF DISCHARGE. Maximum stage recorded during period of record, 

0.62 foot at 12.15 p. m. April 10 (discharge, 9.4 second-feet); minimum stage, 

0.34 foot August 31 and September 1, 1924 (discharge, 3.5 second-feet).

ICE. Stage-discharge relation not affected by ice.

REGULATION. Flow regulated by discharge through nozzle for impulse wheel 

in power house, but opening in nozzle is changed only about twice a day, 

minor variations in load being *aken care of by deflection of nozzle.

ACCURACY. Stage-discharge relation permanent. Rating curve well denned. 

Staff gage read to hundredths twice daily except December 17 to March 22 

and April 1-12, when only one daily reading was obtained. Daily discharge 

ascertained by applying to rating table daily or mean daily gage height. 

Records good.

Water is diverted at dam on East Fork of Wallowa River into a conduit, 16 to 18 

inches in diameter, and carried 1 mile to power house. After leaving power house 

the water follows a tortuous channel for a quarter of a mile and discharges into 

West Fork. Elevation of crest of dam above nozzle at power house is 1,160 feet.
