AUTHORIZATION AND SCOPE OF WORK

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

measurements of flow made on streams in the United States during 

the year ending September 30, 1924.

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 9.

Measurements of stream flow have been made at about 4,990 

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

Hawaiian Islands. In July, 1924, 1,670 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, evaporatibn, storage reservoirs, river profiles, 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 secondfeet, 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, acre-feet, and millions of cubic 

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, 1923, and ending September 30, 1924. At the beginning of 

January in most parts of the United States much of the precipitation 

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
EXPLANATION OP DATA O

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 

direct reading 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 by the general methods 

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.

FIGURE 1. Typical gaging station

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.

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

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

The description of the station gives, in addition to statements 

regarding location and equipment, information in regard to any conditions that may affect the permanence of the stage-discharge relation, covering such subjects as the occurrence of ice, the use of the
4 SURFACE WATER SUPPLY, 1924, PART XII B

stream for log driving, shifting 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 

fluctuation 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 quantities of 

discharge for regular intervals during the day, or by means of a 

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 

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

of observation of stage, measurement 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 the daily gage height to the rating table to obtain the daily 

discharge.

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
PUBLICATIONS O

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" previously published 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 sections of the 

United States are located above most of the diversions from those 

streams, and the discharge recorded does not show the water supply 

available for further development, as prior appropriations below the 

station must first be satisfied. 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 table of monthly discharge gives 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 year may be expected to throw new 

light on data previously published.

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, ground 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 monographs, bulletins, professional papers, and annual reports.

The results of stream-flow measurements are now published annually in 12 parts, each part covering an area whose boundaries coincide 

with natural drainage features as indicated below:

PART I. North Atlantic slope basins (St. John River to York River).

II. South Atlantic slope and eastern Gulf of Mexico basins (James River to 

the Mississippi).

III. Ohio River Basin.

IV. St. Lawrence River Basin.

V. Upper Mississippi River and Hudson Bay Basins.

VI. Missouri River Basin.

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 

each year. An index of the reports containing records obtained prior 

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

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

1923. The data for any particular station will 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 

SKTAKE RIVER AT SOUTH BOUNDARY OF YELLOWSTOKTE WATIOWAI 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. 490 square miles (measured on topographic maps). 

RECORDS AVAILABLE. June 19, 1913, to September 30, 1924. 

GAGE. Stevens eight-day water-stage recorder on right bank; installed July 20,

1921; read by Peters and Newell. Overhanging chain gage on right bank

2^4 miles above used only as reference gage. 

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. Conditions at auxiliary location similar except that the stream is

in one channel at all stages. 

EXTREMES OF DISCHARGE. Maximum stage recorded during period May 20 to

September 30, 6.39 feet at 10 p. m. May 20 (discharge, 4,310 second-feet);

minimum stage, 2.39 feet at 5 a. m. September 4 (discharge, 205 second-feet). 

1913-1924: Maximum stage recorded, 7.45 feet June 12, 1923 (discharge,

6,280 second-feet); minimum stage, 1.4 feet October 26-31, 1915 (discharge,

160 second-feet). 

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

prevented by hot springs above gage. 

DIVERSIONS. None above station. 

REGULATION. None. 

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

Operation of water-stage recorder satisfactory. Daily discharge obtained

by applying mean daily gage height to rating table. Records good. 

COOPERATION. Part of gage-height record and one measurement furnished by

United States Bureau of Reclamation.

SNAKE RIVER WEAR MORAW, WYO.

LOCATION. In sec. 17, T. 45 N., R. 114 W., IK miles below Moran post office, 

Teton County, and United States Bureau of Reclamation dam at outlet of 

Jackson Lake. No important tributaries between dam and station.

DRAINAGE AREA. 820 square miles.

RECORDS AVAILABLE. September 21, 1903, to September 30, 1924.

GAGE. Vertical staff in two sections on left bank. Datum lowered 1.0 foot July 

25, 1915. Stevens water-stage recorder installed June 14, 1917, on bank to 

rear of staff gage. Gage read by Joseph Markham.

DISCHARGE MEASUREMENTS. Made from cable 100 feet below gage or by wading.

CHANNEL AND CONTROL. Bed of gravel and boulders. Control practically permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.60 feet at 8 

p. m. July 19 (discharge, 9,080 second-feet); minimum discharge, estimated 

19 second-feet December 16-31 (stage-discharge relation affected by ice). 

1903-1924: Maximum stage recorded, 10.41 feet at 8 p. m. June 12, 1918 

(discharge, 15,100 second-feet); practically no flow during a few days in 1907 

and 1909 as a result of closing of gates in Jackson Lake Dam.

ICE. Stage-discharge relation affected by ice. Gates in dam at Jackson Lake 

are closed during winter. Flow past gage represents leakage through dam 

and inflow from springs.

DIVERSIONS. None between dam and station and practically none above Jackson Lake.

REGULATION. Flow controlled by operation of gates in Jackson Lake Dam. 

Storage capacity of reservoir 847,000 acre-feet.
SNAKE EIVER 13

ACCURACY. Stage-discharge relation permanent after July 1. Rating curve well 

denned; parallel curves used May 25 to June 7 and June 9-23. Operation of 

water-stage recorder satisfactory. Daily discharge May 25 to September 30, 

ascertained by averaging the hourly discharge obtained by applying mean 

hourly gage height from the recorder graph to the rating table; shifting-control method used June 8, 9, and 24-30. Records excellent.

COOPERATION. Gage-height record and two discharge measurements furnished 

by United States Bureau of Reclamation.

GREAT FEEDEE CANAL NEAR EIEIE, IDAHO

LOCATION. In sec. 36, T. 4 N., R. 40 E., 700 feet below head of canal, 4 miles 

east of Ririe, and 14 miles southeast of Rigby, Jefferson County. Diversion 

gates of canal 2 miles below Heise gaging station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 31, 1923, to September 30, 1924.

GAGE. Friez water-stage recorder on left bank; inspected by Ira Moore.

DISCHARGE MEASUREMENTS. Made from cable 500 feet below gage or by wading.

CHANNEL AND CONTROL. Bed composed of cobbles and gravel drift. Banks 

fairly clean. One channel for all stages. Control fairly permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during periods October 1 

to December 8 and May 3 to September 30, 7.1 feet May 17-18 (discharge, 

3,930 second-feet); minimum discharge probably occurred during period of 

no record.

1923-1924: Maximum stage recorded, 7.10 feet May 17-18, 1924 (discharge, 3,930 second-feet); minimum stage, 2.67 feet on September 25, 1923 

(discharge, 591 second-feet).

ICE. Stage-discharge relation seriously affected by ice. Observations discontinued during winter.

DIVERSIONS. None above nor below gage of sufficient importance to affect 

stage-discharge relation.

REGULATION. Flow is regulated by canal head gates.

ACCURACY. Stages-discharge relation not entirely permanent. Standard rating 

curve and one parallel curve used. Shifting-control method employed for 

short period. Operation of water-stage recorder satisfactory except for 

short period. Daily discharge obtained by applying mean daily gage height 

to rating table except as shown in footnote to table of daily discharge. 

Records good.

DIVERSIONS FROM SNAKE RIVER BETWEEN HEISE AND SHEIIEY 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 heading of each canal by the United States 

Geological Survey for the Idaho State Department of Reclamation to facilitate
SNAKE RIVER

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

30, 1924.

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

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

to hundredths daily May 19 to September 30. Records good.

Combined daily discharge, in second~feet, of canals diverting from Snake River 

between Heise and Shelley gaging stations for the irrigation season of 1924

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. 

DKAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 18, 1915, to September 30, 1924. 

GAGE. Friez 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 500 feet below gage. Banks high and clean at gage and control. 

EXTREMES OP DISCHARGE. Maximum stage recorded during period, October

1-19 and April 1 to September 30, 8.40 feet at 4 p. m. June 2 (discharge,

11,000 second-feet); minimum stage, 3.61 feet at 1.30 p. m. September 19

(discharge, 666 second-feet).

1915-1924: Maximum stage recorded, 16.97 feet at 1.30 p. m. June 17,

September 19, 1924 (discharge, 666 second-feet).
20 SURFACE WATER SUPPLY, 1924, PART XII B

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

discontinued during winter.

DIVERSIONS. Practically the entire normal summer flow of the 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 project and 

Twin Falls tracts.

ACCURACY. Stage-discharge relation practically permanent. Rating curves 

fairly well defined. Operation of recorders satisfactory except April 13-17, 

April 25 to May 2, May 4-6, and 10. Daily discharge obtained by applying 

to rating table mean daily gage height from recorder graph, except for estimated periods, April 13-17, April 25 to May 2, and May 4-6, and interpolated discharge May 10. Records good.

DIVERSIONS FROM SNAKE RIVER BETWEEN SHELLEY AND BLACKFOOT BRIDGE GAGING

STATIONS, IDAHO

Between Shelley and Blackfoot Bridge gaging stations, 14 separate canals 

divert water from Snake 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 May 19 to September 30, 1924, division of record 

made from Shelly to Porterville Bridge station the latter being discontinued at 

end of 1923 irrigation season.

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

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

to hundredths daily May 19 to September 30. Records good.

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

between Shelley and Blackfoot Bridge gaging stations for the irrigation season 

of 1924

22 SURFACE WATER SUPPLY, 1924, PART XII B

SNAKE RIVER (NOS. 1 AND 2 CHANNELS) BELOW BLACEFOOT BRIDGE, NEAR 

BLACEFOOT, IDAHO

LOCATION. In NW. M T. 3 S., R. 35 E., one-half mile below Blackfoot highway 

bridge and 2 miles west of Blackfoot, Bingham County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 24 to September 30, 1924.

GAGE. Friez water-stage recorder on left bank of No. 2 channel one-fourth mile 

below head of island where No. 1 channel comes out of river; inspected by 

D. G. Taylor.

DISCHARGE MEASUREMENTS. Made from cables (No. 1 channel one-fourth mile 

above gage; No. 2 channel 50 feet below gage) or by wading.

CHANNEL AND CONTROL. Bed composed of cobble in gravel drift. Control subject to occasional shifts. Banks low and subject to overflow at high stages. 

Two channels at gage, except at low stages, when No. 1 channel is dry.

EXTREMES OF DISCHARGE. Maximum stage recorded during period, 5.15 feet at 

11 p. m. June 2 (discharge, 7,800 second-feet); minimum stage, dry on 

numerous days in summer.

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. One 

small canal diverts between this station and the station at Clough ranch.

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

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

tracts.

ACCURACY. Stage-discharge relation fairly permanent. Rating curve welldefined. Operation of water-stage recorder satisfactory except July 31 to 

September 30, when stage was too low to record; May 2, 8, and 9, when 

clock stopped; and June 13, when inlet pipe did not function. Daily discharge ascertained by applying to rating table mean daily gage height determined from inspecting recorder graph or as noted in footnote to table o* 

daily discharge. Records good, except for August and September for which 

they are fair.

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.

SNAKE RIVER (NO. 3 CHANNEL) BELOW BLACKFOOT BRIDGE, NEAR BLACKFOOT, IDAHO

LOCATION. In NW. M T. 3 S., R. 35 E., 2 miles below Blackfoot highway 

bridge and 3^ miles southwest of Blackfoot, Bingham Cpjunty.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 3 to September 30, 1924.

GAGE. Friez recorder on right bank; inspected by D. G. Taylon

DISCHARGE MEASUREMENTS. Made from cable 40 feet below gage or by wading.

CHANNEL AND CONTROL. Bed composed of coarse gravel over cobbles. Banks 

not subject to overflow except at extremely high stages. One channel at 

gage, several overflow channels cross island between Nos. 2 and 3 channels 

at high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during period, 3.81 feet 

at 1 a. m. June 3 (discharge, 1,390 second-feet); minimum stage, dry on 

several days during August and September.

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. One 

small canal diverts between this station and the station at Clough ranch.
24 SURFACE WATER SUPPLY, 1924, PART XII B

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.

ACCUBACY. Stage-discharge relation fairly permanent. Rating curve well 

defined. Operation of water-stage recorder satisfactory. Daily discharge 

ascertained by applying to rating table mean daily gage height obtained by 

inspection of recorder graph, by interpolation, 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 BIACKFOOT BRIDGE AND CIO UGH GAGING STATION,

IDAffO

Between Blackfoot Bridge and Clough gaging station, 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.

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

fairly well defined. Gage read to hundredths daily May 24 to September 30. 

Discharge estimated May 1-23. Records fair.

SNAKE RIVER AT CLOUGH RANCH, NEAR BLACKFOOT, 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 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, 1924,

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 OF DISCHARGE. Maximum stage recorded during year, 6.76 feet at 

8 a. m. June 3 (discharge, 9,330 second-feet); minimum stage, 1.48 feet 

September 1-2 (discharge, 131 second-feet).

1910-1924: 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).

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 summer 

flow is released water from these reservoirs.

ACCURACY. Stage-discharge relation changed during winter. Standard rating 

curves well denned. Operation of water-stage recorder satisfactory except 

during periods of coldest weather, when occasional staff gage readings were 

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

rating table, except as noted in footnote to daily-discharge table. Records 

good.

SHAKE RIVER AT WEEIEY, IDAHO

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

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

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

spring water enter Snake River between this station and station near 

Blackfoot. Raft River enters 18 miles below Neeley. 

82484 29 3
28 SURFACE WATER SUPPLY, 1924, PART XII B

DRAINAGE ABBA. Not measured.

RECORDS AVAILABLE. March 17, 1906, to September 30, 1924.

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

by A. J. Ayers.

DISCHARGE MEASUREMENTS. Made from cable at gage.

CHANNEL AND CONTROL. Bed 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, 7.0 feet at 

noon June 3 (discharge, 12,100 second-feet); minimum stage 3.46 feet at 7 

a. m. September 5 (discharge, 1,780 second-feet).

1906-1924: Actual maximum stage doubtful; maximum mean daily stage, 

13.5 feet June 20, 1918 (discharge, 48,400 second-feet); minimum stage, 3.46 

feet at 7 a. m. September 5, 1924 (discharge, 1,780 second-feet).

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 project and Twin Falls tracts. New power plant completed at American Falls during 1924 causes considerable diurnal fluctuation 

at station.

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

1-11. Eating curve well defined above 2,000 second-feet; fairly well defined 

below that stage. 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 or as noted 

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

February, for which they are fair.

SNAKE RIVER NEAR MINIDOKA, IDAHO

LOCATION. In sec. 2, T. 9 S., R. 25 E., 100 yards below Howells Ferry, 1 mile 

below United States Bureau of Reclamation dam, 6 miles southeast of 

Minidoka post office, Minidoka County, nearest railroad point, and 6 miles 

above Montgomerys Ferry gaging station, which was discontinued December 

31, 1910. Raft River enters between this station and station at Neeley.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 21, 1910, to September 30, 1924.

GAGE. Friez water-stage recorder on right bank; inspected by employees of 

United States Bureau of Reclamation.

DISCHARGE MEASUREMENTS. Made from cable 50 feet below gage.

CHANNEL AND CONTROL. Bed composed of coarse gravel. One channel at all 

stages. Control shifts slightly.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.36 feet at

2 p. m. October 28 (discharge, 7,780 second-feet); minimum stage, 4.13 

feet from 6 to 10 a. m. September 23 (discharge, 1,440 second-feet).

1910-1924: Maximum stage recorded, 16.02 feet at 1 a. m. June 21, 1918 

(discharge, 45,900 second-feet); minimum stage, 4.05 feet from 11 a. m. to

3 p. m. October 13, 1914 (discharge, 960 second-feet).

ICE. Some shore ice forms near gage and river closes farther down; stagedischarge relation slightly affected at times.

DIVERSIONS. The North Side and South Side (Minidoka) Canals divert water 

between the Neeley and Minidoka stations. The nearest diversions below 

the station are Twin Falls North Side and South Side Canals at Milner.
SNAKE EIVEE 31

EEGULATION. Flow partly regulated by storage in Lake Walcott above Minidoka 

Dam (storage capacity about 67,090 acre-feet above spillway).

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

well defined above 2,000 second-feet; one parallel curve used. Second 

parallel curve used to define period January 4-27, when stage-discharge 

relation was slightly ice affected. Operation of water-stage recorder satisfactory. Daily discharge ascertained by applying mean daily gage height 

to rating table using shifting-control method January 3 and 28-31. Records 

good.

COOPERATION. Gage-height record and three discharge measurements furnished 

by United States Bureau of Eeclamation.

LAKE MILKER AT MILNER, IDAHO

LOCATION. In sec. 29, T. 10 S., R. 21 E., in backwater of Twin Falls Co.'s dam 

at Milner, Cassia County.

RECORDS AVAILABLE. April 10, 1911, to September 30, 1924.

GAGE. Hook gage supplemented by float gage in same well at dam; latter installed June 1, 1920, consists of target which moves directly with large float 

in well and automatically indicates stage on graduated scale above gagehouse floor. A Lietz and a Friez water-stage recorder have also been used

NOTE. Qage height is the mean of two daily observations.
SNAKE RIVER 33

SNAKE RIVER AT MILKER, 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, 1924.

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

May 28, 1919; 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 gage datum of 15 feet; full 

river width above that point. Control practically permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during the year, 10.85 feet 

at 1. p. m. October 24 (discharge, 6,480 second-feet); minimum stage, 1.50 

feet August 22-26 (discharge, 8 second-feet).

1909-1924: Maximum stage recorded, 20.1 feet (originalgage) June 12,1909 

(discharge, 44,400 second-feet); minimum flow occurred at gage height 1.50 

feet August 22-26, 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 taken by 

these canals.

REGULATION. Flow past the station during the irrigation season is regulated at 

Milner Dam.

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

defined. Operation of .water-stage recorder satisfactory except during 

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

Daily discharge ascertained by applying mean daily gage height to rating 

table except Apr. 9,15,16,18-20, when marked changes occurred, when mean 

of hourly discharge was used. Records good.

COOPERATION. Gage-height record and 3 discharge measurements furnished by 

Twin Falls Canal Co.

second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. No water diverted from 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 the 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 well 

defined. 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.

COOPERATION. Gage-height record and two discharge measurements furnished 

by Idaho Power Co.

SNAKE EIVEE NEAR TWIN FAILS, IDAHO

LOCATION. In sec. 33, T. 9 S., R. 17 E., at Perrine Bridge, on Blue Lakes ranch, 

4 miles north of Twin Falls, Twin Falls County, and 4 miles below Shoshone 

Falls. Outlet of Blue Lakes enters Snake River 200 feet below gage and 

Salmon Falls Creek enters 18 miles below.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 29,1911, to June 30,1917, and May 1,1919, to 

September 30, 1924.

GAGE. Combined inclined and vertical staff set in concrete, on left bank 100 

feet above bridge; installed August 18, 1921; read by employees on Blue 

Lakes ranch.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Bed at measuring section very rough. Banks high; 

not subject to overflow. Control composed of lava boulders and solid 

rock; practically permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 6.7 feet at 

4.15 p. m. October 24, 7.10 a. m. October 25, and 7 p. m. October 29 (discharge, 7,960 second-feet); minimum stage, 2.0 feet May 25 and 27 (discharge, 

475 second-feet).

1911-1917; 1919-1924: Maximum stage recorded, 13.3 feet at 6 a. m. 

and 7 p. m. June 10,1914 (discharge, 32,200 second-feet); minimum discharge, 

468 second-feet, several periods in June, July, and August, 1915.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. No water is diverted from the river between this station and that 

at Milner, except by small ranch ditches.

REGULATION. Flow past station regulated directly by diversions of North Side 

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

diverted during latter 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 probably permanent. Rating curve well 

defined. Gage read to quarter-tenths twice daily. Daily discharge ascertained by applying mean daily gage height to rating table. Records good.

SNAKE RIVER NEAR HAGERMAN. 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 10 miles below.

DRAINAGE AREA. Not measured.

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

September 30, 1924.

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 OF DISCHARGE. Maximum stage recorded during year, 4.7 feet October 25 and 30 (discharge, 12,600 second-feet); minimum discharge measured, 

4,690 second-feet, September 6.

1912-1917; 1919-1924: Maximum stage recorded, 7.75 feet at 6 p. m. 

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

15 to August 2,1915 (discharge, 4,030 second-feet). Data insufficient in 1916 

and 1917 for determination of maximum and minimum stages.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. No important diversions between this station and 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 regulated by diversions of the Twin Falls canals at Milner.

ACCURACY. Stage-discharge relation changed October 8-25. Well-defined rating curve used October 1-7 and curve parallel thereto October 26 to September 

30. Water-stage recorder operated satisfactorily except for short periods in 

April, June, and September. Daily discharge ascertained by applying to 

rating table mean daily gage height determined by inspecting recorder graph, 

except as indicated in footnote to table of daily discharge. Records for October to January, good; February to September, excellent.

SNAKE RIVER AT KING HILL, IDAHO

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, 1924.

GAGE. Inclined staff on right bank installed August 24, 1922; read by 

employees 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, 8.77 feet February 8 (discharge, 15,800 second-feet); minimum discharge, 6,070 secondfeet several days during May to September.
40 SURFACE WATER SUPPLY, 1924, PART XII B

1909-1924: 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 practically permanent. Rating curve well 

defined. 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. ^ sec. 18, T. 2 S., R; 1 E., Ada County, three-quarters of 

a mile below Swan Falls-power plant, 12 miles east of Murphy, Owyhee 

County, and 38 miles below mouth of Bruneau River.

DKAINAGE ABEA. 41,900 square miles (measured on United States Land Office 

maps).

RECOBDS AVAILABLE. August 29 to October 31, 1912; August 21, 1913, to 

September 30, 1924.

GAGE. Au water-stage recorder installed July 31, 1924, replaced a Friez recorder 

in use since September 7, 1914, on right bank a quarter of a mile below ranch 

house of S. N. Glass; inspected by George Bahler.

DISCHAKGE MEASUKEMENTS. Made from boat at ferry cable 1J£ miles above 

gage.

CHANNEL AND CONTROL. Bed composed of lava rock with deposits of sand, silt 

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

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

recorder, 6.26 feet at 9 a. m. February 9 (discharge, 18,700 second-feet);, 

minimum mean daily discharge, 6,130 second-feet, June 29 and July 4; 

absolute minimum stage and discharge not definitely known because water 

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

1912-1924: 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 in 1919 to 1924, 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 probably permanent. Rating curve fairly 

well defined. Operation of water-stage 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 

fair.

The following discharge measurement was made:

September 2, 1924: Gage height, 0.34 foot; discharge, 7,400 second-feet.

DISCHARGE MEASUREMENTS. Made from cable 200 yards below bridge.

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

EXTBEMES OF DISCHARGE. Maximum stage recorded during year, 6.60 feet 

February 9 (discharge, 28,900 second-feet); minimum stage, 1.35 feet August 

5 (discharge, 5,100 second-feet.)

1910-1924: Maximum stage recorded, 13.60 feet May 23, 1921 (discharge, 

83,100 second-feet); minimum stage, 1.35 feet August 5, 1924. 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 not affected by ice.

DIVERSIONS. Some water is diverted between Weiser and the station near 

Murphy by pumping.

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

at Swan Falls power plant above.

ACCURACY. Stage-discharge relation practically permanent. Rating curve welldefined. 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 Weather Bureau.

SNAKE RIVER AT OXBOW, OEEG.

LOCATION. In NW. % 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 1*4= miles southeast of Copperfield post office.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 22, 1923, to September 30, 1924.

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

inspected by William T. Kingsley and L. W. Goodin. Prior to December 

20, 1923, an inclined staff at present site and datum was used.

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, 13.42 feet at 11 a. m. February 9 (discharge, 30,800 secondfeet); minimum stage, 6.30 feet from 5 to 6 a. m. August 6 (discharge, 4,890 

second-feet).

1923-1924: Maximum stage recorded, 15.5 feet June 12, 1923 (discharge, 

42,900 second-feet); minimum stage and discharge occurred August 6, 1924.

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.

ACCURACT. Stage-discharge relation assumed to have changed slightly October 

16-24. Rating curve well defined. Gage read to hundredths once daily prior 

to December 20, and at other times during April, May, and June when water 

was below inlet pipe as noted in footnote to table of daily discharge; waterstage recorder satisfactorily operated during remainder of year. Daily 

discharge ascertained by applying daily gage height to rating table except as 

noted in footnote to table of daily discharge. For periods water-stage 

recorder was operated, mean daily gage height determined by inspection of 

recorder graph. Records excellent July to September; others good.

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 the water. Records 

are available from June 1, 1919, to September 30, 1924.

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

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

to hundredths daily May 19 to September 30. Records good.
TRIBUTARY BASINS

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

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, 1924.

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

Rating curves fairly well defined. Gages read to hundredths daily May 19 to 

September 30. Records good.

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

gaging station near Squirrel, Idaho, for the irrigation season of 1924

FALL RIVER NEAR SQUIRREL, IDAHO

LOCATION. In sec. 35, T. 9 N., R. 44 E., 9 miles southeast of Marysville, 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, 1924. Three miles above at Wilson's sawmill August 24,1902, 

to December 31, 1903.

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

T. W. 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 riffle 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, 3.48 feet 

at 8.30 a. m. May 21 (discharge, 1,920 second-feet); minimum stage, 1.46 

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

1904-1909; 1918-1924: 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 on canal above station.

ACCURACY. Stage-discharge relation practically permanent; affected by ice 

November 29 to February 13. Two rating curves used during year differing 

very little except in shape and at low stages. Gage read to hundredths once 

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

table. Records good.

DIVERSIONS FROM FALL RIVER BETWEEN SQUIRREL AND CHESTER GAGING STATIONS, IDAH'G

Between Squirrel and Chester gaging stations nine separate canate 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 sare available 

from June 1, 1919, to September 30, 1924.
62 SURFACE WATER SUPPLY, 1924, PART XII B

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. 

Gages read to hundredths daily May 19 to September 30. Records good.

DIVERSIONS FROM TETON RIVER BETWEEN GAGING STATION NEAR ST. ANTHONT 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, 1924.

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

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

daily May 19 to September 30. Records fair.

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

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

of 1924

GRATS 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, 1924.

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, 5.00 feet at 3.30 p. m. April 25 (discharge, 775 second-feet) ; 

minimum discharge, 1.0 second-foot, May 26-31, August 27-31, September 

1-4 and 14-17. Lower flow may have occurred during period of no record. 

1916-1924: 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 foi 

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 some water has been diverted from south 

end of lake through Clark cut into Meadow Creek Basin and thence into 

Blackfoot-Marsh Reservoir.

REGULATION. Some regulation after May 25, 1924, due to construction of dam 

at outlet of lake.

ACCURACY. Stage-discharge relation permanent during year. Rating curves 

well defined. Operation of water-stage recorder unsatisfactory. Staff gage 

read to hundredths about once a week after August 1. Daily discharge ascertained by applying mean daily gage height to rating table except as indicated 

in footnote to table of daily discharge. During periods water-stage recorder 

was operated, mean daily gage heights were determined by inspection of 

recorder graph. Records fair.

IDAHO (GOVERNMENT) CANAL NEAR SHELLEY, IDAHO «

LOCATION. In sec. 31, T. 1 N., R. 37 E., 600 feet below canal head gates, 1J£ 

miles southwest of Shelley, Bingham County, and 10 miles above point where 

Sand Creek crosses canal.

RECORDS AVAILABLE. June 20,1912, to September 30,1924. No water diverted 

during 1913 because of break in canal.

GAGE. Friez water-stage recorder on right bank installed September 12, 1923. 

Datum of gage about 0.12 foot lower than original gage. Recorder inspected 

and daily staff readings made by M. A. Jensen and D. G. Taylor.

DISCHARGE MEASUREMENTS. Made from suspension footbridge at gage or by 

wading.

CHANNEL AND CONTROL. Trapezoidal concrete rating section. Growth of weeds 

and brush causes changes in stage-discharge relation, but bottom of rating 

section evidently furnishes a permanent point of zero flow at gage, height of 

about 0.0 foot.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 4.79 feet at 

1 a. m. May 20 (discharge, 681 second-feet); minimum discharge, practically 

no flow during period of no record and on days reported dry by observer.

1912-1924: Maximum stage recorded, 4.83 feet August 12, 1920; maximum discharge, 681 second-feet on May 20, 1924; minimum discharge, 

practically no flow during periods of no record when head gates were closed.

ICE. Canal not operated during winter.

DIVERSIONS. None.

REGULATION, Flow controlled at head gates 600 feet above.

ACCURACY. Stage-discharge relation changed during winter. Standard rating 

curves well defined. Daily discharge October 4-27, November 14-18, 

May 8 to July 6, July 8-15, ascertained by applying to rating table mean 

daily gage height obtained from recorder graph or frOm daily staff gage 

readings; for other periods of record it was ascertained by use of observers' 

notes. Records good.

Idaho (Government) Canal diverts water from left bank of Snake River in 

sec. 31, T. 1 N., R. 37 E. and discharges into Blackfoot River in sec. 24, T. 2 

S., R. 36 E. The canal also receives water from Sand Creek about 10 miles 

below station.

BIACEFOOT RIVER ABOVE RESERVOIR, NEAR HENRY, IDAHO

LOCATION. About sec. 9, T. 7 S., R. 42 E., at Swanson ranch, 1^ miles above 

flow line of Blackfoot-Marsh Reservoir, 7 miles south of Henry, Caribou 

County, and 13 miles north of Soda Springs.

DRAINAGE AREA. 360 square miles (measured on Land Office map).

RECORDS AVAILABLE. March 25, 1914, to September 30, 1924.

GAGE. Vertical staff on right bank to rear of Swanson's house and 500 feet 

below highway bridge; installed June 23,1921; read by Mrs. A. C. Swanson.

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

CHANNEL AND CONTROL. Bed rough; composed of loose rocks and boulders 

with some gravel. Control of loose rock, fairly permanent. One channel 

at ordinary stages; two or three channels at high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.00 feet 

April 24 (discharge, 1,110 second-feet); minimum discharge, 40 second-feet, 

August 28 to September 5. Lower flow may have occurred during winter. 

1914-1924: Maximum stage estimated from high-water mark above gage, 

6.85 feet May 16, 1917 (discharge, 2,060 second-feet); minimum stage, 

0.98 foot August 17, 1919 (discharge, 23 second-feet). Minimum discharge 

probably occurred during periods of no record.

ICE. Stage-discharge relation affected by ice; records discontinued during 

winter.
74 SURFACE WATER SUPPLY, 1924, PART XII B

DIVERSIONS. A few small ranch diversions are made above gage.

REGULATION. None. Entire flow passing gage is stored in Blackfoot-Marsh 

Reservoir 1J^ miles below.

ACCURACY. Stage-discharge relation changed several times after high water due 

to accumulation of moss and debris on control. Rating curves well defined. 

Gage read to hundredths once daily. Daily discharge ascertained by applying daily gage height to rating table; shifting-control method used May 10 

to June 5, August 20-31, and September 21-30. Records good, except for 

estimated periods for which they are poor.

COOPERATION. Several discharge measurements furnished by United States 

Office of Indian Affairs.

BI,ACKFOOT-MARSH RESERVOIR NEAR HENRY, IDAHO

LOCATION. In sec. 12, T. 5 S., R. 40 E., 12 miles northwest of Henry, Caribou 

County, and 45 miles southeast of Blackfoot.

RECORDS AVAILABLE. January 1, 1912, to September 30, 1924.

GAGE. 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.

EXTREMES OF STAGE. Maximum stage recorded, 56.05 feet June 10; minimum 

stage, 42.00 feet October 9, 11, 13, 14, 17, and 18.

1912-1924: Maximum stage recorded, 68.60 feet June 27-30, 1912; minimum stage, 40.76 feet September 28 and 29, 1919.

ACCURACY. Gage moved several times during year on account of construction 

work on dam. As some of the gage settings were probably not checked 

by level, part of the record may be slightly in error with respect to datum.

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

Affairs.

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

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

50,000 acres. The reservoir 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 

reservoir is 17 miles long and 5^j 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 feet. The capacity of the reservoir 

at elevation of crest of spillway is 303,000 acre-feet. Elevation of lowest point to 

which water may be drawn is 6,090 feet. The distribution system comprises 56 

miles of main canal, 108 miles of laterals, and 3Mi miles of drainage ditch.

78 SURFACE WATER SUPPLY, 1924, PART XII B

BLACKFOOT RIVER NEAR SHELLEY, IDAHO

LOCATION. In sec. 7, T. 2 S., R. 38 E., 1J^ 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 important tributaries.

DRAINAGE ABBAS. Not measured.

RECORDS AVAILABLE. June 26, 1909, to September 30, 1924. 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 approximately 50 second-feet.

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

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, 5.11 feet 7 a. m. to 2 p. m. July 20 (discharge, 997 second-feet)," 

minimum stage, 3.09 feet at 2 a. m. December 21 (discharge, 31 second-feet). 

1909-1924: Maximum stage recorded, 6.30 feet at 9 p. m. July 23, 192£ 

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

January 23, 1919 (discharge, approximately 15 second-feet). Ice jam 

above station caused temporary drop in stage.

ICE. Stage-discharge relation seriously affected by ice.

DI'VERSION. No noteworthy diversions are made from river or tributaries above 

station.

REGULATION. Flow regulated largely 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. Standard 

rating curves fairly well defined. Shifting-control method used July 4. 

Operation of water-stage recorder fairly satisfactory, except during periods 

of ice effect when weekly staff, readings were obtained. Daily discharge 

ascertained by applying mean daily gage height to rating table, except for 

periods of ice effect and for periods of no record as indicated in footnote 

to table of daily discharge. Records fair.

minimum stage, 0.95 foot June 29 (discharge, 2.6 second-feet). According to 

marks on banks, a considerably higher discharge occurred sometime prior 

to May 4.

1914-1924: 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. Two well-defined rating 

curves used, applicable, respectively, October 4-13 and May 4 to September 

11. Operation of water-stage recorder satisfactory except for short periods 

in October, May, and June. Daily discharge ascertained by applying1 torating table mean daily gage height determined by inspection of recorder 

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

SAND CREEK NEAR FIRTH, IDAHO

LOCATION. In sec. 7, T. 2 S., R. 37 E., 400 feet downstream from point where

Idaho (Government) Canal crosses creek and 4 miles east of Firth, Bingham

County. 

RECORDS AVAILABLE. December 21, 1916, to June 30, 1924, when station was

discontinued. 

 GAGE. Vertical staff on left bank, just above highway bridge; read by P. W.

Wernette. 

DISCHARGE MEASUREMENTS. Made by wading, from highway bridge, or from

small flume crossing creek 50 feet downstream.
86 SUKFACE WATER SUPPLY, 1924, PART XII B

CHANNEL AND CONTKOL. Bed composed of silt, sand, and fine gravel; probably 

not permanent. Banks clean but subject to overflow at high stages. Point 

of zero flow, about 0.2 foot gage height; measured October 11, 1921.

EXTREMES OF DISCHARGE. Maximum discharge recorded during period, 31 

second-feet at 7 a. m. May 25; creek dry April IB-24.

1916-1924: Maximum discharge recorded at gage-height 4.34 feet at 7 

a. m. April 3, 1919 (discharge, 348 second-feet). Flow zero on days when 

regulation head gate was closed.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. None between canal crossing and station.

REGULATION. The Idaho (Government) Canal has been constructed directly 

across the channel of the creek above station. The canal receives the 

entire flow of the creek as tributary and regulates the flow returned to the 

creek channel below by means of head gates. Above this point numerous 

canal systems utilize the creek channel as a waste ditch.

ACCURACY. Stage-discharge relation not permanent; affected by ice December 9 

to* March 31. Standard rating curve well defined. Gage read to hundredths 

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

to rating table; shifting-control method used April 29 to June 1. Records 

good for open-channel season; fair for ice-affected period.

FORT HALL LOWER CANAL NEAR BLACKFOOT, IDAHO

LOCATION. In sec. 15, T. 3 S., R. 35 E., 200 feet below ford where road to head' 

gates half a mile above crosses canal and 2J^ miles southeast of Blackfoot,. 

Bingham County.

RECORDS AVAILABLE. May 15, 1912, to June 30, 1924, when station was discontinued.

GAGE. Stevens eight-day water-stage recorder on right bank; installed July 14,. 

1921; read by ditch rider for United States Office of Indian Affairs.

DISCHARGE MEASUREMENTS. Made from suspension footbridge at gage.

CHANNEL AND CONTROL. Channel at gage is trapezoidal concrete rating section,, 

at sides of which sand and silt have been deposited. Principal control is 

wooden check across canal about one-third mile below gage. Variations 

in amount of water carried in a large lateral that diverts between gage and 

check and growth of moss and weeds in canal caused several changes in* 

stage-discharge relation.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.50 feet 

May 24 (discharge, 321 second-feet); canal dry during various periods in 

winter.

1912<-1924: Maximum stage recorded, 4.51 feet at 6 a. m. July 9, 1922 

(discharge, 544 second-feet). Canal reported dry on numerous dates.

ICE. No record obtained during winter. Small quantities of water are run at 

times for use of stock, but during greater part of winter the head gates areclosed.
TRIBUTARY BASINS 89

DIVERSIONS. None above gage; one large and one small lateral divert between 

gage and check that forms main control.

REGULATION. Flow regulated at head gates half a mile above gage.

ACCURACY. Stage-discharge relation not permanent; affected by variation in 

quantity of water diverted just below gage, by variable conditions at control, 

and by growth of aquatic vegetation. Standard rating curves fairly well 

defined. Shifting-control method used June 12. Partly estimated October 5. 

Operation of water-stage recorder satisfactory. Daily discharge ascertained 

by applying mean daily gage height obtained from inspection of recorder 

graph to rating table except days when shifting-control method was used or 

estimate made. Records fair.

Fort Hall Lower Canal diverts water from left bank of Blackfoot River in sec. 

11, T. 3 S., R. 35 E. Water is used for irrigation on Fort Hall Indian Reservation. 

The following discharge measurements were made: 

April 30, 1924: Gage height, 1.70 feet; discharge, 87.9 second-feet. 

June 10, 1924: Gage height, 2.46 feet; discharge, 171 second-feet. 

June 24, 1924: Gage height, 2.14 feet; discharge, 182 second-feet.

TRIBUTARY BASINS 91

CAMAS CREEK NEAR DUBOIS, IDAHO

LOCATION. In NE. M SB. M sec. 13, T. 11 N., R. 38 E., 2 miles north of Lone 

Tree Reservoir, 2 miles downstream from 18-mile shearing corral, 5% 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).

RECOBDS AVAILABLE. April 11, 1921, to September 30, 1924.

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

Geological Survey engineers.

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

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

flood channel to the left of main channel and unites above the gage. Measured by wading at low and medium stages 300 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 period from waterstage recorder, 2.02 feet April 16 (discharge, 138 second-feet); minimum 

stage, 0.65 foot from 4 p. m. June 5 to 9 a. m. June 6 (discharge, 8.5 secondfeet) . Maximum discharge probably occurred about April 25 during period 

of no record.

1921-1924: Maximum stage recorded, 5.75 feet probably on May 21, 1922 

(discharge, 1,550 second-feet); minimum stage and discharge occurred in 

1924.

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

during winter,

DIVERSIONS. Two stock-watering ditches of 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 

2,000 to 3,000 acre-feet, on West Camas Creek, and released during lowwater period for use above gag'ing station.

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

applicable after April 14, well-defined between 10 and 200 second-feet. 

Operation of water-stage recorder not wholly satisfactory. Daily discharge 

ascertained by applying to rating table mean daily gage height determined 

by inspection of recorder graph. Records good except for interpolated and 

estimated periods for which they are fair.

IITTLE LOST RIVEE AT RAYMOND RANCH, NEAR HOWE, IDAHO

LOCATION. In sec. 29, T. 10 N., R. 27 E., at Raymond ranch, 1J^ miles above 

Wet Creek and 32 miles northwest of Howe, Butte County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 13, 1921, to September 26, 1924, when station was 

discontinued. From August 28, 1910, to October 3, 1913, records were collected at station on Little Lost River near Clyde, Idaho, 2J^ miles upstream.

GAGE. Prior to April, 1924, vertical staff on left bank 100 feet above wagon 

bridge; thereafter, vertical staff on left bank just below bridge and 145 

feet below original location; at different datum. Gages read by Mrs. Nelle 

Raymond.

DISCHARGE MEASUREMENTS. Made from wagon bridge or by wading.

CHANNEL AND CONTROL. Bed composed of gravel and sand; subject to change 

at high stages. Control fairly well defined at low stages but affected by 

choking of channel below at high stages. Banks overflowed during extremely 

high water.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.00 feet at 

7.30 a. m. May 19 (discharge, 103 second-feet); minimum stage, 0.92 foot 

at 8 p. m. July 22 (discharge, 20 second-feet). A lower discharge probably 

occurred during winter when no record was obtained.

1921-1924: Maximum stage, 4.33 feet, obtained from high-water marks 

on gage post, occurred sometime between June 7 and 29, 1921; discharge 

not determined. Minimum discharge estimated, 14 second-feet, January 

16-20, 1922 (stage-discharge relation affected by ice).

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

DIVERSIONS. Several small ranch diversions above and numerous diversions for 

irrigation below. Water that is stored in the Blaine County Investment 

Co.'s reservoir on Dry Creek, a tributary that enters Little Lost River 

some distance above gage, is diverted during irrigation season through a 

pipe line and open ditch over small divide into Corral Creek, thence into 

Wet Creek through which water flows into Little Lost River below station and is used for irrigation on the company's project about 30 miles 

downstream.

REGULATION. None except as affected by diversions above.

ACCURACY. Stage-discharge relation not permanent. October 1 to December 

15 curve parallel to rating curve which is well defined between 30 and 140 

second-feet was used; April 18 to September 26 rating curve which is well 

defined between 15 and 80 second-feet was used. Gage read to hundredths 

usually twice daily. Daily discharge determined by applying daily gage 

height to rating table except December 10 and 11 and May 12-27 during 

which latter period stage-discharge relation was affected by choking channel 

conditions below and a backwater curve based upon measurement was used. 

Records good except for May, for which they are fair.

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

gage to a point about 15 miles above.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Two well-defined rating 

curves and one parallel curve were used, applicable, respectively, October 1 

to December 7, May 16-26 and June 15 to September 30, and May 31 to 

June 8. Operation of water-stage recorder fairly 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; shifting-control method used May 27-30 and June 

9-14. Records fair.

COOPERATION. Gage-height record and several discharge measurements furnished by water commissioner for Big Lost River.

The record at this station represents a 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 located 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 105,113, and 115, respectively. For combined flow of both 

channels of Big Lost River and both channels of Warm Spring Creek, see page 107.

BIG IOST RIVER (WEST CHANNEL) ABOVE MACKAY RESERVOIR, NEAR MACKAY, IDAHO

LOCATION. In sec. 5, T. 7 N., R. 23 E., 3 miles above Mackay Dam, above flow 

line of reservoir, and 7% miles above Mackay, Ouster County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 9, 1919, to September 30, 1924.

GAGE. Stevens eight-day water-stage recorder on left bank; installed May 4, 

1920; inspected by employees of Utah Construction Co.

DISCHARGE MEASUREMENTS. Made from suspension footbridge just above gage 

or by wading.

CHANNEL AND CONTROL. Bed composed chiefly of gravel. Channel winding. 

Banks subject to overflow at extremely high stages. Control of gravel, fairly 

well defined, but subject to change.

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

1.65 feet May 20 and 21 (discharge, 141 second-feet); minimum stage, 0.97 

foot April 1-20 (discharge, 22 second-feet).

1919-1924: Maximum discharge estimated, 1,200 second-feet from highwater mark on gage (4.45 feet) during period June 5-16, 1921, when waterstage recorder was not operating. Minimum discharge from actual discharge 

measurement, 18.3 second-feet May 1, 1920.

ICE. Ice formation negligible on account of spring inflow above.

DIVERSIONS. None between station and reservoir. Several canals divert water 

above the "dry beds" which extend from a point a few miles above station 

to a point about 15 miles above near Chilly. No surface flow passes the 

"dry beds" except during fairly high stages.

REGULATION. None.

ACCURACY. Stage-discharge relation changed slightly May 16 and 17 and June 

10-15. Well-defined rating curve and a curve parallel thereto were used. 

Operation of water-stage recorder satisfactory except for several short periods. Daily discharge ascertained by applying to rating table mean daily 

gage height obtained by inspection of recorder graph, except as noted in 

footnote to daily-discharge table; shifting-control method used May 16, 17, 

and June 10-15. Records good.

COOPERATION. Gage-height record and several discharge measurements furnished by water commissioner for Big Lost River.

MACKAY RESERVOIR WEAR 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, 1924. 

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, 54.85 feet

April 24-27 (contents, 29,850 acre-feet); minimum stage, 6.95 feet August

5 (water surface below bottom of outlet tunnel).

1919-1924: 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. 

COOPERATION. 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 

the Utah Construction Co.'s Carey Act project. About 5,200 acres are 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 the reservoir, which is 

not available for use. Elevation of crest of spillway corresponds to 62.0 feet on 

gage, at which stage the capacity of the reservoir is 38,400 acre-feet, about 2,400 

acres of land being submerged. As the foundation of the dam is on very porous 

material and the 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 the reservoir occasionally falls below the bottom of the outlet tunnel. A study of the 

stream-flow records at this point indicates that most of the seepage from the 

reservoir reappears in the river channel above the gaging station at the " Narrows"
TRIBUTARY BASINS 109

1*^5 miles downstream, where favorable rock structure forces underground water 

*to the surface. Additional water also reappears, part of which is probably side 

drainage while part evidently flows underground at the places where the surface 

flow into the reservoir is measured and thence through the 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 LOST RIVER BELOW MACKAY RESERVOIR, NEAR MACKAY, IDAHO

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

half a mile above heading of Streeter ditch, 13^ miles below Mackay Dam,

and 2^2 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, 1924. 

'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 1 mile below present site. Streeter ditch

diverts water between these two points.

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

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

growth at times affects stage-discharge relation. 

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

3.02 feet October 14 (discharge, 812 second-feet); minimum stage, 1.25 feet

noon to midnight November 6 (discharge, 46 second-feet).

1903-1906; 1912-71915; 1919-1924: Maximum stage recorded, 5.79 feet

June 10, 1921 (discharge, 2,990 second-feet); minimum stage, 0.36 foot

March 26-28, 1914 (discharge, 41 second-feet).
110 SURFACE WATER SUPPLY, 1924, PART XII B

ICE. Stage-discharge relation not affected by ice.

DIVEESIONS. 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.

ACCURACY. Stage-discharge relation changed slightly October 15-28 and September 1-9, for which shifting-control methods were used. For remainder of 

year three well-defined rating curves were used. Operation of water-stage 

recorder satisfactory. Daily discharge ascertained by applying to rating 

table mean daily gage height determined by inspecting recorder graph, 

except for periods for which shifting-control methods were used. Records 

good.

COOPERATION. Gage-height record and several discharge measurements furnished 

by water commissioner for Big Lost River.

WARM SPRING CSEEK (EAST CHANNEL) NEAR HACEAY, IDAHO

LOCATION. In NE. ^i sec. 5, T. 7 N., R. 23 E., 500 feet above junction with 

west channel of Warm Spring Creek, 3?^ miles above Mackay Dam, and 

7J^ miles northwest of Mackay, Custer County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 1, 1919, to September 30, 1924.

GAGE. Vertical staff on right bank; read by employees of Utah Construction Co.

DISCHARGE MEASUREMENTS. Made from suspension bridge 125 feet above gage 

or by wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel. One channel at 

all stages. Banks steep and covered with brush. Channel congested by 

growth of moss during summer.

EXTREMES OP DISCHARGE. Maximum discharge recorded during year, 52* 

second-feet May 19 and 20; minimum discharge, 13 second-feet May 5-10- 

Actual maximum and minimum flow may have occurred on days of no record1919-1924: Maximum discharge recorded, 225 second-feet June 15,. 

1922; minimum discharge, 9 second-feet May 8, 9, 13, 14, 1919, and May18-21, 1920.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Natural flow practically all diverted during irrigation seasonFlow during summer represents return flow from irrigation above. Entireflow stored in Mackay Reservoir 3J-£ miles below.

REGULATION. None.

ACCURACY. Stage-discharge relation affected by growth of moss and by brush 

along banks. Well-defined rating curve used February 28 to March 27; shifting-control method used during remainder of year. Gage read to hundredthsonce or twice a week. Daily discharge ascertained by applying gage height 

to rating table and by interpolation for days when gage was not read. 

Records fair chiefly because of infrequent gage readings and because of 

changing channel conditions.

COOPERATION. Gage-height record and several discharge measurements furnished by water commissioner for Big Lost River.

The record at this station represents a portion of the natural flow of Big Lost 

River and taken in conjunction with the record for west channel of Warm SpringCreek and east and west channels of Big Lost River will show the entire surfaceflow of Big Lost River which enters Mackay Reservoir a short distance below - 

For record from station on west channel of Warm Spring Creek and east and westchannels of Big Lost River see pages 115, 103, and 105, respectively. For record 

of combined flow of both channels of Big Lost River and Warm Spring Creek see

DIVERSIONS. Numerous ranch diversions above gage. The largest single diversion is canal of Portneuf-Marsh Valley Canal Co., which irrigates land near 

Downey.

REGULATION. None below head of Portneuf-Marsh Valley Canal Co.'s canal. 

Storage reservoir of company near Chesterfield has capacity of about 28,000 

acre-feet.

ACCURACY. Stage-discharge relation changed during winter and from July 23 

to September 19. Two well-defined rating curves used; one applicable 

October 1 to December 30, the other February 6 to July 22; September 20-30 

curve parallel to latter curve used. Gage read to half-tenths several times 

a week. Daily discharge ascertained by applying daily gage height to rating 

table for days when gage was read and by interpolation for intervening days; 

shifting-control method used July 23 to September 19. Open-water records 

good; winter records fair.

NORTH SIDE TWIN FALLS CANAL AT MILNER, IDAHO

LOCATION. In sec. 20, T. 10 S., R. 21 E., Jerome County, half a mile north of 

Milner post office, Twin Falls County, and three-fourths of a mile below 

head gates at Milner Dam.

RECORDS AVAILABLE. May 10, 1909, to September 30, 1924.

GAGE. Stevens eight-day water-stage recorder on right bank; installed April 1, 

1918; inspected by McConnel and Gilham.

DISCHARGE MEASUREMENTS. Made from cable at gage.

CHANNEL AND CONTROL. Channel is a permanent concrete-lined section. Growth 

of moss heavy during summer and stage-discharge relation is seriously 

affected. Control apparently indeterminate.

EXTREMES OF DISCHARGE. Maximum stage recorded, 8.75 feet at 9 a. m. May 9 

(discharge, 3,020 second-feet); canal dry October 4-11.

1909-1924: Maximum discharge occurred at gage height 8.68 feet July 

5-7 and 29-31, 1921 (discharge, 3,200 second-feet); canal dry many times 

when head gates were closed.

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

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 regulated by head and waste gates.

ACCURACY. Stage-discharge relation not permanent; changes due largely to 

growth of aquatic plants. Standard rating curve well defined; many parallel 

curves used. Operation of water-stage recorder satisfactory. Staff gage read 

to hundredths once daily November 1 to March 31 and twice daily for remainder of year. Daily discharge ascertained by applying to rating table mean 

daily gage height obtained from staff reading or by inspecting recorder graph; 

also by shifting-control method. Records good November to March; excellent for October and from April to September.

COOPERATION. Gage-height record and 46 discharge measurements furnished 

by North Side Canal Co. (Ltd.).

The North Side Twin Falls Canal diverts water from the north side of Snake 

River at the 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.

ROCK CREEK REAR 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 33^ miles northwest of Twin 

Falls, Twin Falls County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 27, 1922, to September 30, 1924.

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

by H. T. Henderson and T. T. Rutledge.

DISCHARGE MEASUREMENTS. Made from highway bridge at gage 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 OP DISCHARGE. Maximum stage during year from water-stage 

recorder, 3.35 feet at 5 a. m. November 12 (discharge, 563 second-feet); 

minimum stage, 1.01 feet from 3 p. m. to midnight August 3 (discharge, 94 

second-feet).

1922-1924: Maximum stage recorded, 3.43 feet at 7 p. m. July 23, 1923 

(discharge, about 589 second-feet); minimum discharge occurred August 3, 

1924.

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 permanent during year. Rating curve 

well defined below 400 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. Records good.

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

BIG WOOD RIVER AT HAILEY, 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, 1924.

GAGE. Vertical staff on right bank; installed April 6, 1920; read by R. F. 

Bowman.

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 changes at high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.80 feet May 

17 (discharge, 587 second-feet); minimum discharge, 0.1 second-foot September 10-20.

1915-1924: Maximum stage recorded, 5.70 feet June 12, 1921 (discharge, 

3,560 second-feet); minimum discharge, September 10-20, 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 the flow 

of Big Wood Slough is being obtained (see page 151), 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 during winter. Rating curves 

fairly well defined. Gage read to hundredths once daily. Daily discharge 

ascertained by applying daily gage height to rating table. Records good 

except for estimated periods for which they are fair.

COOPERATION. Two 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 RESEEVOIE NEAE RICHFIELD, IDAHO

LOCATION. In NE. Y± SE. Y± 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, 1924. 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% inch well casing which 

serves as a stilling well, bolted to face of tower. Reading made by attendants 

at the dam. Observations are referred to an assumed datum which is about 

137 feet lower than sea level.

 COOPEBATION. 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 

Tock filled 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 SLOUGH AT HAILEY, 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, 1924. 

GAGE. Vertical staff 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 subject to overflow. One channel at all stages. Control formed

by a wood-stave water pipe, laid in bed 15 feet below gage; changes slightly. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 1.90 feet at

2.40 p. m. July 5 (discharge, 251 second-feet); minimum stage, 1.00 foot

April 17 (discharge, 18 second-feet).

1915-1924: 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 but

slightly by this factor. 

ACCURACT. Stage-discharge relation practically permanent during year.

Rating curve fairly well defined. Gage read to hundredths once daily.

Daily discharge ascertained by applying daily gage height to rating table.

Records fair. 

COOPERATION. Four 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 the Hailey power plant. The 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, will show the entire flow of the 

river at this point. For record from station on the main river see page 139. For 

record of combined flow of Big Wood River and Big Wood Slough see page 140.

length. Zero of gage set to agree with average elevation of weir crest.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 1.30 feet 

June 8 (discharge, 90 second-feet); minimum stage, 0.14 foot, September 29 

(measured discharge, 3.1 second-feet). Lower flow occurred during period 

of no record.

1919-1920; 1923-1924: Maximum stage recorded, 1.46 feet August 3 

and 5, 1923 (discharge, 108 second-feet); minimum stage, 0.08 foot February 

15, 16, and 21, 1920 (discharge, 1.5 second-feet). Probably not actual 

extremes.

JOE. Stage-discharge relation probably affected by ice; records discontinued

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Bed composed of coarse sand and gravel. One channel 

at all stages. Control formed by Cippoletti weiT with 12-foot crest. Zero 

of gage corresponds to average elevation of weir crest.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 0.22 foot 

April 20 (discharge, 4.2 second-feet); minimum discharge, 0.1 second-foot, 

several times after June 26. Probably not actual extremes.

1920-1922; 1924: 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. Probably not actual 

extremes.

ICE. Stage-discharge relation affected by ice.

DIVERSION. One small diversion above gage.

REGULATION. None.

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

used based on standard weir formula for 12-foot Cippoletti weir which has 

been fairly well substantiated by several discharge measurements made in 

1923 and 1924. Gage read to hundredths nearly every day in May and June; 

readings made infrequently at other times. Daily discharge determined by 

applying daily gage height to rating table except for days of missing records 

for which it was interpolated as noted in footnote to table of daily discharge. 

Records fair.

IONG TOM RESERVOIR NEAR BENNETT, IDAHO

LOCATION. In sec. 35, T. 1 S., R. 7 E., 8 miles southwest of Bennett, Elmore

County, and 17 miles northeast of Mountain Home. 

DRAINAGE AKEA. Not measured. 

RECORDS AVAILABLE. April 3 to June 25, 1924. 

GAGE. Readings obtained by measuring with steel tape from top of upstream

corner of masonry gate tower on southeast end of dam; read by C. J.

McGrath. Elevations referred to datum of Mountain Home Cooperative

Irrigation Co. 

EXTREMES OF STAGE. Maximum stage recorded during period of record, 4,446.22

feet May 1; minimum stage, 4,406.73 feet June 25. 

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 the Mountain 

Home feeder canal and used for irrigation on about 5,000 acres of land near 

Mountain Home.

The reservoir is formed by a gravity earth dam 400 feet in length at crest. 

The 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 reservoir is about 4,040 acre-feet, about 153 acres 

of land being submerged.

COOEEBATION. 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 

the 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 

the reservoir at that stage being 259,000 acre-feet. A movable crest is provided 

for the spillway, the top of which is at elevation 3,211 feet. The capacity of the 

reservoir at that stage is 276,500 acre-feet, and about 2,900 acres of land is

DIVERSIONS FROM BOISE RIVER, IDAHO

Below mouth of Moore Creek and between gaging stations at Dowling ranch 

and Notus, 27 principal canals and a number of small farm laterals divert water 

from Boise River for use in irrigation.

Daily gage-height records were obtained, frequent discharge measurements 

made, and records summarized under direction of A. V. Tallman, water master 

for Boise River.

Records are available from 1919 to 1924. Record of daily diversions subsequent to 1915 is on file in office of Idaho commissioner of reclamation.

NOTE. Gates in dam reported opened on Apr. 1 for release of water through Little Camas Canal. Reservoir empty 9n May 31 when gates were closed. Readings on May 28-29 do not represent actual reservoir stages owing to fall in low stage outlet channel from main body of water to point under reference point 

where readings were made. Under present condition of outlet channel, the lowest stage to which main 

body of water in reservoir can actually be drawn is at an elevation of about 4,931.00 feet.

MALHEUR RIVER 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 ABEA. About 1,100 square miles.

RECORDS AVAILABLE. December 9, 1914, to July 4, 1917; Msrch 18, 1919, to 

September 30, 1924. From January 3,1906, to March 31,1907, and December 15, 1908, to May 25, 1910, records were obtained at a site 4 miles 

below, at Riverside.

GAGE. Vertical staff on left bank installed April 28, 1920;

DISCHARGE MEASUREMENTS. Made from a highway bridge a 

below dam or by wading.

CHANNEL, AND CONTROL. Concrete control 200 feet below gage 

poor quality and disintegrates during winter. Above a 

concrete control is submerged and contraction and riffle 

downstream acts as control for gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during 

1-13 (discharge, 435 second-feet); seepage was estimated 

when gates to reservoir were closed October 30, 1923, 

September 29 and 30, 1924.

1906-1924: Maximum discharge recorded, 5,490 second 

1910 (gage height on Riverside gage, 10.0 feet); minimum 

prior to construction of dam, practically no flow durin 

determined by subtracting discharge of South Fork from 

river below South Fork. Minimum discharge since cons 

somewhat less than 1 second-foot when gates are closed; 

August 1 to September 16, 1919, while dam was being constructed.

ICE. No water released from dam during winter.

DIVERSIONS. 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 above 4.2 feet changed probably due to 

scouring of river bed below crest of artificial control by ice during winter. 

Rating curves well defined. Staff gage read tohundredths once a day and 

time noted when change was made in gate openings at dam. Daily discharge ascertained by applying daily gage height to rating table. Records 

fair.

GAGE. Stevens eight-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 wide. The cut-off walls at ends conform to slope of the banks. 

The control was reconstructed in November, 1922, extending cut-off wall 

deeper into bed and banks of stream and adding a concrete apron 6 feet long.

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

recorder, 2.25 feet at 5 p. m. February 8 (discharge, 116 second-feet). No 

flow October 1-30 and July 6 to September 30.

1904-1906; 1910-1915; 1921-1924: Maximum discharge (computed from 

cross section and estimated velopities) 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 

meadow land; reservoir No. 3 just below. The Eldorado ditch diverted 

no water into Willow Creek, 25 miles above gaging station, in 1924.

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

Operation of water-stage recorder satisfactory November 6 to December 9, 

February 7 to March 5, and April 1 to May 22; staff gage read once every 

other day for remainder of year except July 10 to September 30 when there 

was practically no flow. Daily discharge ascertained by applying to rating 

table daily gage height or mean daily gage height determined from recorder 

graph by inspection. Records good.

No discharge measurements made during year; rating checked by measurements 

during 1925.

(discharge, 18,900 second-feet); minimum discharge, September 17, 1924.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Several diversions for irrigation from tributaries above.

REGULATION. During spring and summer flow past station slightly affected by 

regulation at outlet of Payette Lake, 58 miles above.

ACCURACY. Stage-discharge relation changed on December 22, in January, 

May 22 to June 14, and June 22-29, by deposits of material wasted down 

left bank and onto control from blasting and excavating side hill cut for 

new highway. Standard rating curve well defined. Gage read to hundredths once daily. Daily discharge ascertained by applying daily gage 

height to rating table; shifting-control method used May 22 to June 14 and 

June 22-29. Records good except during estimated periods for which 

they are fair.

KORTH FORE OF FAYETTE BIVER AT LARDO, IDAHO

LOCATION. In sec. 8, T. 18 N., R. 3 E., a quarter of a mile below Lardo, Valley 

County, and outlet of Payette Lake. No tributaries enter between lake 

and gage.

DRAINAGE AREA. 131 square miles (measured on topographic and Land Office 

maps).

RECORDS AVAILABLE. September 1, 1908, to June 30, 1917; May 24, 1919, to 

September 30, 1924.

GAGE. Friez water-stage recorder on left bank, installed December 19, 1923; 

staff gage read prior to that date. Gage read by F. L. Williams.

DISCHARGE MEASUREMENTS. Made from cable half a mile below gage or by wading.

CHANNEL AND CONTROL. Bed and control composed of cobbles and gravel; 

slightly shifting. One channel at all stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year from waterstage recorder, 5.90 feet from 5 to 6 a. m. May 13 (discharge, 2,490 secondfeet); minimum stage, 1.23 feet December 20-23 (discharge, 7 second-feet). 

1908-1917; 1919-1924: Maximum stage recorded, 7.5 feet June 5, 1909 

(discharge, 4,250 second-feet); minimum discharge, 3 second-feet October 21 

and 22, 1911, and November 10-26, 1919.

ICE. Stage-discharge relation not 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. From 1919 to 1923, some regulation effected during July, August, and 

September, by installation and later gradual removal of temporary dam 

about 500 feet above present dam.

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

defined. Gage read to hundredths once daily October 1 to December 15, 

except for intervening periods of missing readings as noted in footnote to 

table of daily discharge. Water-stage recorder operated satisfactorily during 

remainder of year. Daily discharge ascertained by applying daily gage 

height to rating table, or for days having large range in stage, by averaging 

discharge for intervals of the day. During period water-stage recorder was 

operated mean daily gage height determined by inspection of recorder graph 

Records excellent except for estimated periods for which they are fair.

COOPERATION. Gage-height record furnished by United States Forest Service.

recorder, 3.11 feet from 2 to 4 a. m. May 14 (discharge, 1,070 second-feet); 

minimum stage, 1.12 feet August 29 (discharge, 75 second-feet). Actual 

maximum stage and discharge probably occurred May 16 or 17 when waterstage recorder was not operating.

1921-1924: Maximum stage recorded, 4.53 feet at 3 a. m. May 26, 1922 

(discharge, 3,080 second-feet); minimum stage and discharge recorded, 

August 29, 1924.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during ice-affected period December 2 to March 29. Rating curves fairly well defined. Operation of waterstage recorder satisfactory except during winter and for few other short 

periods. 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 except December 2, 

March 30, April 6, and 13, when daily staff gage readings were used. Records 

good July to September; others fair;

214 SURFACE WATER SUPPLY, 1924, PART XII B

RECORDS AVAILABLE. October 5, 1910, to January 31, 1913; October 1, 1919, to 

September 30, 1924.

GAGE. Stevens continuous water-stage recorder on left bank; installed June 17, 

1924. Vertical staff at same site used prior to that date; read and inspected 

by Willard and J. A. Finn.

DISCHARGE MEASUREMENTS. Made by wading or from highway bridge one-half 

mile below gage.

CHANNEL AND CONTROL. Bed composed of sand and coarse gravel. Banks covered with brush; left bank not likely to be overflowed; right bank subject 

to overflow at extremely high stages. Control formed by poorly defined 

gravel riffle and by log embedded in stream bed below gage; affected at 

times by debris.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.28 feet May 

19 (discharge, 212 second-feet); minimum stage, 0.44 foot June 5 (discharge, 

2.6 second-feet).

1910-1913; 1919-1924: Maximum discharge recorded, 687 second-feet 

April 13 and May 18-23, 1921; minimum discharge, 0.5 second-foot, July 

23-27, 1911.

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

winter.

DIVERSIONS. Several small ditches divert above and below station.

REGULATION. Flow regulated by head gates at Lost Creek Reservoir 12 miles 

above. Gates in dam changed only at infrequent intervals.

ACCURACY. Stage-discharge relation changed slightly several times due to debris 

on control. Standard rating curve well defined. Gage read to hundredths 

once daily prior to June 17; thereafter water-stage recorder was satisfactorily 

operated. For period water-stage recorder was operated, mean daily gage 

height determined by inspection of recorder graph. Daily discharge ascertained by applying daily gage height to rating table. Records good except 

those for April and May, which are fair.

Co.).

RECORDS AVAILABLE. January 1, 1910, to August 21, 1914; May 21, 1920, to 

September 30, 1921; May 22 to September 30, 1924.

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

21, 1920; inspected by Verne Brewer and W. E. Talboy.

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

CHANNEL AND CONTROL. Bed composed of gravel, cobbles, and boulders; very 

rough. One channel at alL stages. Control formed by well-defined rock 

riffle 20 feet below gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year from waterstage recorder, 1.85 feet from noon June 16 to midnight June 18 (discharge, 

53 second-feet); gates in dam above reported closed sometime in February 

after which channel was practically dry until May 22.

LOCATION. Near line between sees. 8 and 9, T. 14 N., R. 2 W., on Gladhart 

Lane, half a mile south of State highway, 4^4 miles east of Cambridge, 

Washington County, 5 miles above mouth, and 7 miles below entrance of 

Grays Creek.

DBAINAQB AREA. 187 square miles (measured on topographic maps and United1 

States Geological Survey base map of Idaho).
TRIBUTARY BASINS 221

RECOBDS AVAILABLE. May 22, 1920, to September 30, 1924.

GAGE. Vertical staff fastened to streamward side of right abutment of highway 

bridge; read by Mrs. W. J. Martin. From September 1 to November 1, 

1923, during construction of new highway bridge, a temporary staff 50d feet 

upstream was used. All readings practically correspond to original datum.

DISCHARGE MEASUREMENTS. Made from highway bridge at gage or by .wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel. Channel winding 

above and below gage. Banks subject to overflow at high stages. Control 

formed by well-defined gravel riffle 75 feet below gage; subject to change 

during high water. Stage of zero flow at gage height 0.55 foot determined 

June 16, 1924.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, about 7.5 

feet as determined by well-defined high-water mark on gage, February 8 

(discharge, about 2,400 second-feet); minimum stage, no flow after July 19. 

1920-1924: Maximum discharge estimated, based on well-defined highwater mark on gage, 2,400 second-feet, February 8, 1924; no flow August 2 

to September 14, September 17-25, 1920, and July 20 to September 30, 1924.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Numerous ditch and canal diversions above, chiefly for irrigation 

of land in Indian Valley.

REGULATION. None except that due to diversions.

ACCURACY. Stage-discharge relation changed following high water on February 8. Rating curves well defined below 250 second-feet. Gage read to 

hundredths twice daily. Daily discharge ascertained by applying mean 

daily gage height to rating table, using shifting-control method February 

9-12. Records good except for discharges above 250 second-feet and during 

estimated periods for which they are fair.

CRANE CREEK NEAR MIDVALE, IDAHO

LOCATION. In SE. % 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-quarters of a mile 

below.

DRAINAGE AKEA. 269 square miles (measured on topographic maps).

RECOKDS AVAILABLE. October 30, 1910, to April 8, 1916; May 1 to September 30, 

1924.

GAGE. Au water-stage recorder on right bank; installed May 2, 1924; inspected 

by Jesse Bain. Prior to May 1,1924, used staff gage at different datum, 100 

feet upstream.

DISCHAKGE MEASUKEMENTS. 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.

EXTKEMES OF DISCHAKGE. Maximum stage during year from water-stage 

recorder, 1.84 feet at noon June 22 (discharge, 184 second-feet); channel 

reported dry May 1, after 10 a. m. September 30, and at other times prior 

to May 1.

1910-1916; 1924: 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
224 SURFACE WATER SUPPLY, 1924, PART XII B

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. 

Operation of water-stage recorder satisfactory June 15-27 and July 9 to September 30. Staff gage read to hundredths twice daily during remaining 

periods. Daily discharge ascertained by applying mean daily gage height 

to rating table, except for estimated periods as indicated in footnote to table 

of daily discharge. Mean daily gage height for period when water-stage 

recorder was operated, determined by inspection of recorder graph.

COOPERATION. Gage-height record furnished in part by Crane Creek Reservoir Administration Board.

CRANE CREEK IRRIGATION DISTRICT CANAL NEAR WEISER, IDAHO

LOCATION. In sec. 7, T. 11 N., R. 3 W., 3J^ miles below diversion dam of

Washington County Irrigation District,8 and 12 miles northeast of Weiser,

Washington County.

RECORDS AVAILABLE. June 23, 1920, to September 30, 1924. 

GAGE. Friez water-stage recorder on right bank installed May 5,1923; inspected

by Lee Cobb, C. C. Herner, and Sylvester Holmes. 

DISCHARGE MEASUREMENTS. Made from plank across flume. 

CHANNEL AND CONTROL. Section of wooden flume and earth canal section forms

control. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.07 feet at 1

p. m. May 26 (discharge, 52 second-feet); canal probably dry prior to March

7 and portions of April 11 and 12.

8 Formed by reorganization of Crane Creek and Sunnyside Irrigation Districts.
TRIBUTARY BASINS

1920-1924: Maximum stage recorded, 2.83 feet (upper location) 4 to 8 

a. m. July 15, 1920 (discharge, 79 second-feet); canal usually dry during 

nonirrigation periods.

DIVERSIONS. None between gage and point of diversion.

REGULATION. Flow controlled by head gates at diversion dam.

ACCURACY. Stage-discharge relation changed somewhat gradually after June 8 

owing to silt deposits below gage. Well-defined rating curve used March 8 to 

June 8; parallel curves based on frequent discharge measurements used after 

June 8. Operation of water stage-recorder satisfactory- April 12 to August 9 

and August 23 to September 6. Staff gage read to hundredths once daily at 

other times except prior to March 26 and after September 6 when readings 

were obtained rather irregularly. Daily discharge ascertained by applying 

mean daily gage height to rating table, or for days having large range in stage 

by averaging discharge for intervals of the day. Mean daily gage height 

obtained by inspection of recorder graph when water-stage recorder was 

operated. Records good April to August; others fair.

COOPERATION. Washington County Irrigation District furnished gage-height 

record.

Crane Creek Irrigation District Canal diverts water from south side of Crane 

Creek in sec. 3, T. 11 N., R. 3 W., 5^4 miles below Crane Creek Reservoir where 

water is released and transported through canal for irrigation of lands of the 

Washington County Irrigation District, aggregating 10,000 acres, of which less 

than 1,500 acres were irrigated in 1924. The district operates about 100 miles of 

canal and irrigation structures under one management.

230 SURFACE WATER SUPPLY, 1924, PART XII B

POWDER RIVER NEAR NORTH POWDER, OREG.

LOCATION. In NE. ^ sec. 12, T. 6 S., R. 39 E., at entrance to short canyon 

below North Powder Valley, 3 miles northeast of North Powder, Union 

County; below all tributaries and return water from irrigation in North 

Powder Valley and near backwater of proposed Thief Valley Reservoir.

DRAINAGE AREA. 775 square miles; at lower end of Thief Valley, 826 square 

miles.

RECORDS AVAILABLE. May 20, 1913, to September 30, 1915; March 10 to July 

31, 1916; February 1 to July 31, 1920; November 21, 1920, to July 26, 1924. 

Records at this station are almost directly comparable with those at station 

below Thief Valley, March 9, 1909. to June 30, 1912, as the inflow between 

two points constitutes only a negligible percentage of the total.

GAGE. Inclined staff on left bank; read by Mrs. H. C. Bid well.

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

CHANNEL AND CONTROL. Bed composed of rocks with some sand; occasional 

slight shifts.

EXTREMES OP DISCHARGE. Maximum stage recorded during period, 2.81 feet 

February 15 (discharge, 392 second-feet); minimum stage, 0.3 foot July 

11-13, 16-19, and 26 (discharge, 1 second-foot.)

1909-1916; 1920-1924: Maximum stage recorded, 8.1 feet May 20, 21, 

24, and 25, 1921 (discharge, 3,010 second-feet); stream dry in August and 

September, 1910.

ICE. Stage-discharge relation affected by ice December 12 to February 10.

DIVERSIONS. Water is diverted from Powder River and its tributaries for 

irrigating 72,000 acres of land above station.

REGULATION. None.

ACCURACY. Stage-discharge relation changed when ice was going out February 

5-10. Rating curve used before change well defined; rating curve used after 

change fairly well defined. Gage read to hundredths once a day. Daily 

discharge ascertained by applying daily gage height to rating table. Records 

good except for estimated period when stage-discharge relation was affected 

by ice for which they are fair.

The following discharge measurement was made:

April 9, 1924: Gage height, 1.74 feet; discharge, 131 second-feet.

.LOCATION. In sec. 20, T. 11 N., R. 15 E., a quarter of a mile below Sunbeam 

Dam and mouth of Yankee Fork, 3 miles above Robinson Bar, 7 miles south 

of Bonanza, 12 miles below Stanley and mouth of Valley Creek, and 17 

miles above Clayton, Custer County.

DRAINAGE AREA. 841 square miles (measured on topographic maps).

HECORDS AVAILABLE. October 28, 1921, to September 30, 1924.

'GAGE. Vertical staff on left bank; read by Peter Ryan and Andrew Brown.

DISCHARGE MEASUREMENTS. Made from cable three-tenths mile below gage.

OHANNEL AND CONTROL. Bed composed of boulders and gravel. Control 

formed by well-defined boulder and rock riffle; practically permanent. 

Banks high. One channel at all stages.

.EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.0 feet 

May 17 and 18 (discharge, 2,820 second-feet); minimum discharge, 281 

second-feet August 22-27 and September 2. (Actual minimum stage of 

0.00 foot occurred August 24.)

1922-1924: Maximum stage recorded, 7.6 feet June 7, 15, and 17, 1922 

(discharge, 6,760 second-feet); minimum discharge, August 22-27 and September 2, 1924.

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. None of importance above station.

.REGULATION. None. Future operation of power plant at Sunbeam Dam may 

affect flow somewhat during low stages due to probable changes in gate 

opening. Power plant not in operation at present.

ACCURACY. Stage-discharge relation unchanged after October 12; affected by 

ice December 16 to January 31. Rating curve well defined between 250 

and 6,000 second-feet. Gage read to hundredths twice daily prior to July 5; 

thereafter once daily. Daily discharge ascertained by applying daily gage 

height or mean daily gage height to rating table, except as indicated in footnote to table of daily discharge. Records fair.

 COOPERATION. Gage-height record furnished by Love & Von Brecht.

YANKEE FORK OF SALMON RIVER NEAR CIAYTON, 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 17 miles west of Clayton, Ouster County.

DRAINAGE AREA. 195 square miles (measured on topographic maps).

RECORDS AVAILABLE. May 3, 1921, to September 30, 1924.

GAGE, Vertical staff on right bank; read by Peter Ryan, Andrew Brown, and 

F. H. 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 for 1924 reduced to datum in use after 

September 17, 1922.

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 denned at low and 

medium stages. Although gradient is steep control is not well defined at 

high stages due possibly to a slight backwater effect from Salmon River when 

it is in flood. One channel at all stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.10 feet May 

20-22 (discharge, 729 second-feet); minimum stage, 0.10 foot at 8 a. m. 

April 5 (discharge, 22 second-feet). Actual minimum may have occurred 

during winter when discharge was not accurately determined.

1921-1924: Maximum stage recorded, 5.24 feet at 8 p. m. June 12, 1921 

(discharge, 3,360 second-feet); minimum stage and discharge recorded April 5, 

1924. 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 changed slightly during ice-affected period 

December 1 to April 4. Rating curves well defined. Gage read to hundredths 

twice daily October 1 to July 18; thereafter gage was read once daily. 

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

rating table. Records good except for estimated periods for which they are
