8UBFACE WATEB StJPPLY OF SNAKE EIYEE BA&IN, 1921

This volume is onj& 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, 1921.

The data presented in these reports were collected by the United 

States Geological Surrey under the following authority contained in 

the organic law (20 Slat. 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 Ibegun ui 18§8 in connection with special studies 

relating to irrigation in the arid West. Sinbe the fiscal year ending 

June 30, 1895, successive sundry civil bills passed by Congress have 

carried the following item and appropriations:

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

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

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

2 SURFACE WATER SUPPLY, 1921, PART XII B

Measurements of stream flow have been made at about 5,200 

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

the Hawaiian Islands. In July, 1921, 1,350 gaging stations were being 

maintained by the Survey and the cooperating organizations. Many 

miscellaneous discharge measurements are. made, at .other points. In 

connection with this work data were also' collected in regard t6 precipitation, evaporation, storage .reservoirs, river profiles, and water 

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

the water-supply papers from time to time.

DEFINITION OF TE&MS

The volume of water flowing in a stream the^ "runoff" or "disr 

qharge" is expressed in various terms,, ;each of , which fras become 

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

into two groups (1) those that represent a rate of flow, as second-feet 

gallons per minute, miners' 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 tsecond-feet, second-feet per 

square mile, run-off in inches, and acre-feet. They may be defined 

,as follows:

" Second-feet" is an abbreviation for " cujbip 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 eubic feet 

of water flowing per second from each square mile of area drained,-on 

the assumption that the run-off is distributed uniformly both asregards 

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 rua-off with rainfall, 

which is usually expressed in depth 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 &re here defined;

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

of gage height to discharge." i- v ,

" Control "; a term used to designate the natural section or stretch of 

the channel or artificial structure below thegage wnich determines th& 

stage-control relation at the gage. It should bb nb^eid that the control 

may not be the same section or sections at all stages.

EXPLANATION OF DATA 3

The "point of zero flow;" for. a gagkig 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, 1920, and ending September 30, ,1921. 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 run-off is possibly a small quantity in the ground; therefore the run-off for. the year beginning October 1 is practically all 

derived from precipitation within the 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 readings on a staff or chain gage or from a water-stage recorder 

that gives a continuous record of the fluctuations. Measurements 'of 

discharge are made with a current meter. (See/ Pis. I, IL) The 

general methods are outlined in standard textbooks on the measure?- 

ment of river discharge.

From the discharge measurements rating tables are prepared that 

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

height to these rating tables, gives the daily discharge from which 

the monthly and yearly mean discharge is determined.

The data presented for each gaging station, in the area covered by. 

this report comprise a description of the station, a table giving results 

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 results of discharge measurements are published, i

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 lelar 

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

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

backwater, > it gives also information as to .diversions, that * .decrease 

the flow at the gage, artificial regulation, maximum and ^minimum 

recorded stages, and tha accuracy of the -records. : , u 

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

second-feet corresponding to the mean of the gage heights- fead <eaeh

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

fluctuation the discharge obtained from the rating table and 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 surf ace 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 pages 2 

and 3, 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 

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 commuted if such errors appear
PUBLICATIONS 0

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. [,

PUBLICATIONS

Investigation of water resources by the Unitedi States Geological 

Survey has consisted in large part of measurements of the volume 

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

but it has comprised also investigation of such closely allied subjects 

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

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

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

appeared in the bulletins, professional papers, monographs, and 

annual reports. - The results of stream-flow measurements are now published 

annually hi 12 parts, each part covering an area whose boundaries 

coincide with natural drainage features as indicated (below:

NOTE, No data regarding stream flow are given in the 15th and 17th annual reports.

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 basin, the numbers of papers on surface-water supply published from 1899 to 1921. 

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 1902 to 1921 for any station in the area covered by 

Part III are published in Water-Supply Papers 83, 98, 128,169, 205, 

243, 263, 283, 303, 323,353,383, 403, 433, 453, 473, 503, and 523, which 

contain records for the Ohio River basin for those years. Results 

of miscellaneous measurements are published by drainage basins.

GAGING-STATION RECORDS

SNAKE RIVER AT SOUTH BOUNDARY OF YELLOWSTONE NATIONAL PARK

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

mile north of Snake River soldier station and south boundary of Yellowstone 

National P; ark, and 25 miles north of Moran, Wyo.

DRAINAGE AREA. 490 square miles (measured on topographic maps).

RECORDS AVAILABLE. June 19,1913, to September 24,1921.

GAGE. Overhanging chain gage on right bank used December 1,1920, to June 27, 

1921; read by W. N. Purdue. Stevens eight-day water-stage recorder used 

July 20 to September 24,1921. Auxiliary chain gage on bridge about 2 J^ miles 

downstream used August 4 to September 2 and September 4-14,1918, and 

July 25 to September 1 and September 3 and 4,1920, and June 28 to July 

19,1921; read by Sheffield and Elder.

DISCHARGE MEASUREMENTS. Made from cable 225 feet below 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 December 

1,1920, to September 24,1921, 6.5 feet at 8 p. m. on May 28 (discharge, 5,580 

 second-feet),; minimum stage record, 2.0 feet February 24 to March 5 (discharge, 287 second-feet).

1913-1921: Maximum discharge, 5,690 second-feet June 2,1914; minimum 

stage recorded, 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 the gage.

DIVERSIONS. None above station.

REGULATION. None.

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

well defined. Two parallel curves used; rating curve for auxiliary gage 

fairly well defined. Operation of water-stage recorder satisfactory July 20 

to September 24. Gage read to half-tenths once daily. Daily discharge 

obtained by applying daily gage height to rating tables except as noted in 

footnote to daily-discharge table. Records fair.

COOPERATION. Gage-height record furnished by superintendent of Yellowstone 

National Park and by the United States Bureau of Reclamation.

RECORDS AVAILABLE. September 25,1910, to September 30, 1921.

GAGE. Friez water-stage recorder on left bank; installed July 8, 1913, and 

referred to combined vertical and inclined staff gage which was used prior 

to that date. Gage inspected by W. J. Kremer and Lena Byington.

DISCHARGE MEASUREMENTS. Made from cable about 300 feet below gage.

CHANNEL AND CONTROL. Bed composed of rock ledge, coarse gravel, and cobblestones. One channel at all stages. Control formed by the Anderson dam, 

parts of which washed out during the high-water periods of 1917 and 1918.

EXTREMES OF DISCHARGE. Maximum stage recorded during period April 4 to 

September 30, 6.91 feet at 5 p. m. on June 14 (discharge, 34,000 secondfeet) ; minimum stage recorded, 0.34 foot at 2 a. m. on September 30 (discharge, 3,550 second-feet).

1910-1921: Maximum discharge, about 52,000 second-feet, June 16,1918; 

minimum discharge, 2,180 second-feet, March 10, 1915.

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

DIVERSIONS. No large diversions above station. A small ditch of about 25 

second-foot capacity diverts water just above station.

REGULATION. Flow controlled to a large extent by storage in Jackson Lake 

reservoir.

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

well defined below 26,000 second-feet. Operation of water-stage recorder 

satisfactory except during short period April 6-9. Daily discharge obtained 

by applying to rating tables mean daily gage height determined by inspection of recorder graph. Records good.

DIVERSIONS FROM SNAKE RIVER BETWEEN HEISE AND SHELLEY GAGING

STATIONS, IDAHO

Between Heise and Shelley gaging stations 47 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 facilitatedistribution of the water. Records are available from June 1, 1919, to September 30, 1921.

Stage-discharge relation on most of the canals affected by growth of aquaticplants or by operation of check gates. Rating curves well defined. Gages read 

to hundredths daily except during September, when occasional readings were 

made. Records good.

Combined daily discharge, in second-feet, of canals diverting from Snake River between Heise and Shelley gaging stations for the irrigation season of 1921

SNAKE RIVER NEAR SHELLEY, IDAHO

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

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

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 18, 1915, to September 30, 1921.

GAGE. Friez water-stage recorder on right bank, standard hook gage in float 

well, and combination vertical and inclined staff gage outside. Observe rs> 

James Thorne and C. A. McCurdy.

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

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

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

EXTREMES OP DISCHARGE. Maximum stage recorded during period April 20 to 

September 30, 13.17 feet at 10 a. m. on June 1 (discharge, 30,400 secondfeet); minimum stage recorded, 5.78 feet at noon on September 30 (discharge, 2,850 second-feet).

1915-1921: Maximum stage recorded, 16.97 feet at 1.30p. m. on June 17, 

1918 (discharge, 47,200 second-feet); minimum stage, 3.68 feet at 9.15 

a. m. August 29, 1919 (discharge, 702 second-feet).

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

discontinued during winter.

DIVERSIONS. Practically the entire natural summer flow of the river above station is appropriated by numerous diversions in the Idaho Falls district.

REGULATION. Natural 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 ourve well 

defined. Operation of water-stage recorder satisfactory except April 20-27 

and September 26-29. Daily discharge obtained by applying to rating 

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

April 21-23, for which it was interpolated. Records excellent.

DIVERSIONS FROM SNAKE RIVER BETWEEN SHELLEY AND PORTERVILLE GAGING

STATIONS, IDAHO

Between the Shelley and Porterville gaging stations nine separate canals divert 

water from Snake River for irrigation. Gaging stations are maintained at heading of each canal by 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, 1921.

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 except during September, wTien occasional readings 

were made. Records good.

SNAKE RIVER AT PORTERVILLE BRIDGE, NEAR BLACKFOOT, IDAHO

LOCATION. In sec. 26, T. 2 S., R. 35 E., 3i miles north of Blackfoot, Bingham 

County, a quarter of a mile below Porterville Bridge and just below heading 

of Danskin canal. Station was formerly maintained at Porterville Bridge, 

above heading of Danskin canal.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 13, 1918, to September 30, 1921, at present site; 

June 12 to September 30, 1916, at sight at Porterville Bridge.

GAGE. Friez water-stage recorder on left bank, referred to hook gage inside well 

and vertical staff outside; installed October 27, 1918, at site of inclined 

gage which has been used since May 13, 1918, but at a datum 1.54 feet 

higher. An auxiliary low-water gage on left bank about 100 yards upstream 

is used during extremely low stages. Gage used prior to September 30, 1916, 

vertical staff on right abutment of Porterville Bridge.

DISCHARGE MEASUREMENTS, Made from cables over two channels about a 

quarter of a mile below gage or by wading.

CHANNEL AND CONTROL. Bed composed of cobble in gravel drift; clean except 

for occasional lodgment of drift. Control shifts at high stages. One channel at gage but divided by an island into two channels at control, except at 

low stages.
20 SURFACE WATER SUPPLY^ 1921, PAET XII B

EXTREMES OF DISCHARGE. Maximum stage recorded during period May 31 to 

September 30, 9.44 feet at 10 a. m. on June 1 (discharge, 28,600 second-feet); 

minimum stage recorded, 3.60 feet at 2.30 p. m. September 29 (discharge, 

1,770 second-feet).

1916; 1918-1921: Maximum stage from inclined gage, 13.5 feet June 17 

and 18, 1918 (discharge, 46,900 second-feet); minimum stage from auxiliary 

low-water gage, 2.07 feet at 9 a. m. on September 16, 1919 (discharge, 30 

second-feet).

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

DIVERSIONS. Practically the entire natural summer flow of the river is diverted 

above the station.

REGULATION. Natural flow during irrigation season is augmented by the release of stored flood waters in Jackson Lake for use on the Minidoka and 

Twin Falls tracts.

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

well defined below 6,500 second-feet. Operation of water-stage recorder 

satisfactory. Daily discharge obtained by applying to rating table mean 

daily gage height determined from inspecting recorder graph and by shifting-control methods. Records May to July, fair; August to September, good.

SNAKE RIVER 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 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, 1921.

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

site and datum as staff gage installed October 1, 1912. Original gage used 

June 6, 1910, to September 30, 1912, was 50 feet above present site. Datum 

of gage raised 0.06 foot June 25, 1911, and 0.03 foot October 1, 1912, when 

newv staff was installed. Observer, 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 from waterstage recorder, 11.51 feet at 1 p. m. on June 1 (discharge, 28,800 second-feet);; 

minimum stage, 3.54 feet from 6 p. m. October 1 to noon of October 2 (discharge, 1,370 second-feet). ;

1910-1921: Maximum stage recorded during period, from water-stage 

recorder, 14'.8 feet (approximately) at 5 p. m. on 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 second-rf eet). ;

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

apparently not affected.

DIVERSIONS. Practically entire natural summer flow of the 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 not permanent. Rating curves well' 

denned. Operation of water-stage recorder satisfactory except during 

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

used. Daily discharge ascertained by applying to rating table staff reading 

or mean daily-gage height obtained by inspecting gage-height graph, except 

as noted in footnote to daily-discharge table. Records good.

SURFACE WATER SUPPLY; 1921, PART Xll B

SNAKE RIVER AT NEELEY, 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-feet of

spring water enter Snake River between this station and station near Black-

. foot. Raft River enters 18 miles below Neeley.

DBAINAGE AKEA, Not measured.

RECORDS AVAILABLE. March 17, 1906, to September 30, 1921.

GAGE. Friez water-stage recorder installed Augusts, 1910, on left bank at same 

site and datum as staff gage previously used. Observer, H. R. Wallis.

DISCHARGE MEASUREMENTS. Made from cable at gage.

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

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

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

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

recorder, 10.97 feet at 6 p. m. June 2 (discharge, 32,200 second-feet); minimum stage, 4.34 feet at 4 a. m. October 3 (discharge, 3,560 second-feet).

1906-1921: Actual maximum stage doubtful; maximum mean daily stage, 

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

3.65 feet August 20-22, 1906 (discharge, 2,220 second-feet).

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Numerous canals near Blackfoot and Idaho Falls divert practically the entise natural summer flow of Snake River.

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

use on Minidoka project and Twin Falls tracts. Diurnal fluctuations sometimes result from operation of power plant 4 miles upstream.

ACCURACY. Stage-discharge relation changed slightly January 13-14, affected 

by ice January 13, 14, and February 8 and 9. Two well-defined rating 

curves used. Operation of water-stage recorder satisfactory except for short 

periods during winter when well was frozen, and September 17-28, when 

float well was being rebuilt. Daily discharge ascertained by applying t» 

rating tables staff reading or mean daily gage height obtained by inspection of recorder graph, except as noted in footnote to table of daily discharge. 

Records excellent.

SNAKE RIVER 27':

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 AKEA. Not measured.

RECORDS AVAILABLE. April 21, 1910, to September 30, 1921.

GAGE. Friez water-stage recorder on right bank directly across river from and 

at same datum as staff gage used prior to August 28, 1911; also Stevens 

long-distance recorder installed in 1915. Gage inspected by employees of 

United States Bureau of Reclamation.

DISCHARGE MEASUREMENTS. Made from cable about 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 during year from water-stage recorder, 13.36 feet at 3 p. m. June 2 (discharge, 32,900 second-feet); minimun 

stage, 5.03 feet at 5 a. m. October 3 (discharge, 2,550 second-feet).

1910-1921: 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; stage-discharge 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.

REGULATION. Flow partly regulated by storage in Lake Walcott above Minidoka dam (storage capacity about 67,000 acre-feet above spillway).

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

well defined between 3,000 and 20,000 second-feet; one parallel curve used. 

Operation of water-stage recorder satisfactory. Daily discharge ascertained 

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

of recorder graph and by shifting-control methods, except December 10-18, 

for which it was interpolated. Records good.

NOTE. Gage-height record is mean of two daily observations.

SNAKE RIVER AT MILNER, IDAHO

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

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

Minidoka station and Milner, and no noteworthy inflow between Milner and 

station near Twin Falls except seepage and spring water.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 10, 1909, to September 30, 1921.
30 SURFACE WATER SUPPLY, 1921, PART XII B

GAGE. Friez water-stage recorder on left bank below highway bridge, referred 

to combination vertical and inclined staff gage; installed May 28, 1919. 

Staff gage in three sections on left bank 400 yards upstream, used October 

20, 1909, to May 27, 1919, except when supplemented by an auxiliary gage 

at different datum in three sections 100 yards downstream. Datum of 

auxiliary gage lowered 1 foot July 30 and 1 foot September 7,1916. Original 

gage used prior to October 20, 1909, was a vertical staff on right bank at 

about the same datum as gage used after that date. Observer, W. N. 

McConnel.

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

foot planks midway between gage and cable, or by wading. Measurements 

may also be made from the suspension highway bridge immediately above 

gage, but measuring conditions at this bridge are poor.

CHANNEL AND CONTROL. Bed of stream 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 elevation 15 

feet gage datum; full river width above that point. Control practically permanent.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage recorder, 21.21 feet at 6 p. m. June 3 (discharge, 27,000 second-feet); minimum stage recorded, 1.61 feet on August 10-12 and 27-28 (discharge, 11.9 

second-feet).

1909-1921: Maximum stage recorded, 20.1 feet (original gage) on June 

12, 1909 (discharge, 44,400 second-feet); minimum stage, 1.08 feet (old 

datum auxiliary gage) August 17-18, 1915 (discharge, 9 second-feet).

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

DIVERSIONS. Twin Falls canals divert water at Milner dam, just above the 

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 below 20,000 second-feet. Operation of water-stage recorder satisfactory except during extreme low stages, when staff gage was read twice 

daily to hundredths. Discharge ascertained by applying mean daily gage 

height to rating table except on days when marked changes occurred, when 

mean of hourly discharge was used. Records good.

COOPERATION. Gage-height record and thirteen discharge measurements furnished by Twin Falls Canal Co.

Discharge measurements of Snake River at Milner, Idaho, during the year ending

32 SURFACE WATER SUPPLY, 1921, PART XII B

SNAKE RIVER NEAR TWIN FALLS, IDAHO

LOCATION. In sec. 33, T. 9 S., R. 17 E., at Perrine's 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, 1921.

GAGE. Combined inclined and vertical staff set in concrete, installed August 

18, 1921, at same site and datum as former inclined staff located on left 

bank, 100 feet above bridge; read by T.-C. Shawver.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Bed of stream at measuring section very rough. 

Banks high; not subject to overflow. Control composed of lava boulders 

and solid rock; practically permarient.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 12.92 feet at 

6 a. m. June 4 (discharge, 30,600 second-feet); minimum stage, 2.22 feet 

July 16-18, 20-23 (discharge, 570 second-feet).

1911-1917; 1919-1921: Maximum stage recorded, 13.3 feet at 6 a. m. 

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

stage recorded, 2.05 feet June 27 to July 4, July 9-16, 18-20, 28, 29, and 

31, August 1-3, 6, and 7, 1915 (discharge, 468 second-feet).

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 the station regulated directly by diversions of the 

North Side and South Side canals at Milner, where practically entire flow 

of river is diverted during the 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 practically 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 though parts of the records of daily discharge may be somewhat in 

error as a result of diurnal fluctuations due to operation of gates at Milner 

dam.

COOPERATION. Services of observer paid by Idaho Power Co.

34 SURFACE WATER SUPPLY, 1921, PART XII B

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, 1921.

GAGE. Friez water-stage recorder installed April 20, 1921, replacing Stevens 

continuous water-stage recorder located on right bank, installed November 

15, 1916, at same datum as former inclined gage. Inspected by employees 

of the Idaho Power Co. Inclined staff on left bank 50 feet below ferry used 

prior to August 15, 1915. Vertical staff at same site used thereafter until 

November 15, 1916. All gages at same datum.

DISCHARGE MEASUREMENTS. Made from cable 100 feet below gage.

CHANNEL AND CONTROL. Control rocky; permanent.

EXTREMES or DISCHARGE. Maximum stage during year, from water-stage recorder, 7.63 feet at 10 a. m. June 3 (discharge, 33,800 second-feet); minimum 

stage, 3.24 feet July 17 (discharge, 4,720 second-feet).

1912-1917; 1919-1921: 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 the one at 

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

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

maintained largely by springs and waste water from irrigation above.

REGULATION. Flow regulated by diversions of the Twin Falls canals at Milner.

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

Daily discharge ascertained by applying to rating table mean daily gage 

height determined by inspecting recorder graph, and by interpolation or estimation as shown by footnote to daily-discharge table. Records, when recorder was in operation, excellent. Estimated periods based upon Twin 

Falls and King Hill records, good.

COOPERATION. Services of observer paid by Idaho Power Co.

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, 1921.

GAGE. Inclined staff on right bank; installed August 17, 1910; read by E. T. 

Giles and M. J. Beach. Original gage, used May 13, 1909, to March 1, 1910, 

was a vertical staff on left bank at practically the same site as present gage, 

but at datum about 2.2 feet higher. Temporary staff gage three-fourths of 

a mile above, used March 7 to August 16, 1910.

DISCHARGE MEASUREMENTS. Made from cable 100 feet below gage.

CHANNEL AND CONTROL. -Bed at gage and measuring section composed largely of 

gravel. Control is lava reef partly overlain with gravel;' shifts slightly.

EXTREMES op DISCHARGE. Maximum stage recorded during yearj 14.48 feet at 

4.55 p. m. June 3 (discharge, 37,900 second-feet); minimum stage, 5.5 feet 

July 14, 16-19, 21, and 22 (discharge, 6,280 second-feet).

1909-1921: 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

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. No important diversions for irrigation are made between this 

station and the one #t Milner.

REGULATION. Flow regulated by diversions at Milner. During;i3ertain parts of 

irrigation season practically the entire flow of the river at Milner is appropriated, and flow at King Hill is derived largely from springs and; i?pepage 

water from the Twin Falls tracts.

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

well defined. Gage read to hundredths once daily. Daily discharge ascertained by applying daily gage height to rating table and interpolating for 

days of no gage heights. Records good.

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

Reclamation.

 stage may have occurred on a day of no record. Minimum stage not definitely known because water fell below inlet pipe at times of minimum load 

at the power plant above.

1912-1921: 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, 1920, and 1921.

ICE. Stage-discharge relation not affected by ice.

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

between this station and that 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 the small relative amount of storage obtained, changes are of short duration.

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

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

periods indicated by breaks in record as noted in footnote to daily-discharge 

table. Daily discharge ascertained by applying to rating table mean 

daily gage height obtained by inspection of recorder graph. Daily discharges good except for periods of estimation, interpolation, or days based 

on partial day gage-height record, which are fair. Monthly summary good.

COOPERATION. Services of an observer furnished by Idaho Power Co.

SNAKE RIVER AT WEISER, IDAHO

LOCATION. In sec. 31, T. 11 N., R. 5 W., a third of a mile above wagon bridge 

at Weiser, Washington County. Between this station and station near 

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

from left and Boise, Payette, and Weiser rivers from right.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 8, 1910, to September 30, 1921. Fragmentary 

gage-height records obtained by Weather Bureau since 1895.

GAGE. Inclined concrete gage on right bank; installed by Weather Bureau; 

read by J. W. Lapish. Elevation of zero of gage is^at 2,087.22 feet above 

sea level. Gage used October 8,1910, to September 30,1914, was an inclined 

staff on right bank about 200 yards below wagon bridge at different datum.

DISCHARGE MEASUREMENTS. Made from cable 200 yards below bridge.

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

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 13.60 feet 

May 23 (discharge, 83,100 second-feet); minimum stage, 2.05 feet July 31 

(discharge, 7,140 second-feet).

1910-1921: Maximum stage recorded. that of May 23, 1921; minimum 

stage, 1.5 feet (Weather Bureau datum) August 28 and 29, 1915, and August 

1, 1919 (discharge, 5,550 second-feet). A stage of 15.7 feet was observed 

March 3,1910, on old Weather Bureau gage (discharge, about 100,000 secondfeet).

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 operation 

of Swan Falls power plant above.

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

Gage read to hundredths once daily. Daily discharge ascertained by applying daily gage height to rating table. Records good, except for extremely 

low water for which they are fair, because owing to diurnal fluctuations 

caused by operation of Swan Falls power plant one daily gage reading may 

not be true index of mean daily flow.

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

SNAKE RIVER AT RIP ARIA, WASH.

LOCATION. In sec. 31, T. 13 N., R. 38 W., at Oregon-Washington Railroad & 

Navigation Co.'s bridge at Riparia, Whitman County.

DRAINAGE AREA. 102,000 square miles (measured by United States WeatherBureau) .

RECORDS AVAILABLE. October 1, 1915, to September 30, 1921. Gage height 

record during parts of May and June, 1900 to 1902, May 1 to November 30, 

1904, July'1,1905, to December 31, 1906, February 1, 1908, to June30,1910, 

and August 1, 1910, to February 28, 1917, obtained and published by 

United States Weather Bureau. .!

GAGE.-^-Chain gage on railroad bridge installed September 12, 1917; read by 

W. W. Pickett, jr. Previous gage was vertical staff in three sections referred 

to same datum; the highest section on first bridge pier from right bank and 

the lower sections on upper draw guard of bridge.

DISCHARGE MEASUREMENTS. Made from railr6ad bridge.

EXTREMES OF DISCHARGE. vlaximum stage recorded during year, 19.0 feet May 

20 (discharge, 270,000 second-feet); minimum stage recorded, 1.5 feet August 

31 (discharge, 16,700 second-feet).

1916-1921: Maximum stage recorded that of May 20, 1921; minimum 

stage recorded, 0.1 foot August 28 to September 5, 1919 (discharge, 10,900 

second-feet); discharge may have been less in December, 1919, when stagedischarge relation was affected by ice.

Maximum stage determined from high-water mark, as published by the 

United States Weather Bureau, 2^.7 feet, June 5, 1894 (discharge, 409,000 

second-feet, estimated by extending rating curve).

CHANNEL AND CONTROL. Control for low stages is sand and gravel channel above 

Texas Rapids; shifting. For high stages control is solid lava bed of Texas 

Rapids half a mile below gage; permanent.

ICE. Stage-discharge relation occasionally affected by ice.

DIVERSIONS. A large amount of water is diverted above gage for irrigation,

REGULATION. Flow is partly regulated by storage in Jackson Lake reservoir 

(capacity, 847,000 acre-feet), Arrowrock reservoir (capacity, 280,000 acrefeet), Deer Flat reservoir (capacity, 177,000 acre-feet), and in other smaller 

reservoirs in the basin; also by diversions for irrigation.

ACCURACY. Stage-discharge relation for low water changed slightly on May 20; 

not affected by ice. Rating curves well defined. Gage read to half-tenths 

' once daily. Daily discharge ascertained by applying daily gage height to 

fating table. Records good.

DIVERSIONS FROM |HENRYS FORK BETWEEN ASHTON AND ST. ANTHONY GAGING

m STATIONS, IDAHO

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

water from Henrys Fork for irrigation. Gaging stations are maintained at heading of each canal by the United States Geological Survey for the Idaho State 

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

available from June 1, 1919, to September 30, 1921.

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

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

to hundredths daily except during September, when occasional readings were 

made. Records good.

Combined daily discharge, in second-feet, of canals diverting from Henrys Fork between Ashton and St. Anthony gaging stations for the irrigation season of 1921

DIVERSIONS FROM FALL RIVER ABOVE GAGING STATION NEAR SQUIRREL, IDAHO

Above the gaging station near Squirrel three separate canals divert water 

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

each canal by the United States Geological Survey for the Idaho State Department of Reclamation to facilitate distribution of the water. Records are available from June 1, 1919, to September 30, 1921.

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

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

GRAYS LAKE OUTLET NEAR HERMAN, IDAHO

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

and 3*4: miles west of Herman, Bonneville County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 5, 1916, to September 30, 1921.

GAGE. Stevens continuous recorder on right bank installed April 20, 1918; inspected by Mrs. C. H. Johnson. Prior to April 20, 1918, vertical staff on 

right bank at practically same location and datum.

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 approximately 3.5 feet. Control 

is rock ledge about 25 feet below gage; practically permanent. Point of 

zero flow determined August 2, 1921, as at gage height 0.43 foot ±0.05 

foot.

EXTREMES OP DISCHARGE. Maximum stage during year, from well-defined 

high-water marks, 5.0 feet on about April 30 (discharge, about 784 secondfeet); minimum stage, 0.8 foot September 27 (discharge, 2.3 second-feet). 

Channel reported practically dry prior to April 16.

1916-1921: 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. Records discontinued during winter. Ice practically stops flow from lake 

at times, but springs probably keep channel near gage free from ice.

DIVERSIONS. No diversions between lake and station. Diversions for irrigation are made above lake, but amount of water diverted is not known.

REGULATION. No artificial regulation above station.

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

well defined. Operation of recorder not entirely satisfactory on account of 

poor attention by observer. Daily discharge ascertained by applying to 

rating table mean daily gage height obtained by inspection of recorder 

graph, and estimating for certain periods when recorder was not operating. 

Records poor May 1-14; fair June 2-19 and for September; and good for 

remainder of period of record.

GAGE. Inclined staff on right bank set in the concrete of rating section; read 

by Antone Christensen.

DISCHARGE MEASUREMENTS. Made from suspension footbridge at the 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 furnished a permanent point of zero flow "at gage height 

about 0.0 foot.

EXTREMES OF DISCHARGE. Maximum stage recorded during period June 1 to 

September 30, 4.48 feet at 10.50 a. m. August 3 (discharge, 443 secondfeet); minimum flow, zero, June 1-14.

1912-1921: Maximum stage recorded, 4.83 feet August 12, 1920 (discharge, 

486 second-feet); minimum flow zero during practically all periods of no 

record, when head gates were closed.

ICE. Canal not operated during winter.

DIVERSIONS. None.

REGULATION. Flow controlled at the head gates 600 feet above.

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

well defined; two parallel curves used. Gage read to hundredths daily. 

Daily discharges ascertained by applying daily gage height to rating table 

except as noted in footnote to daily-discharge table. 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.

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

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 

approximately 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 5^4 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 a«re-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 

3J^ miles of drainage ditch.

recorder, 3.45 feet at 3 p. m. May 15 (discharge, 1*230 second-feet); minimum stage, 0.80 foot November 2-15 (discharge, 9 second-feet). A lower, 

stage and discharge may have occurred during period of no record.

1908-1921: Maximum stage recorded, 4.45 >feet May 14, 1909 (discharge, 

1,640 second-feet); minimum stage, 0.50 foot May: ll, 12, 1917 (discharge, 

about 1 second-foot).

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

DIVERSIONS. Few small diversions for irrigation above reservoir.

REGULATION. Flow entirely regulated by storage in reservoir.

ACCURACY. Stage-discharge relation affected by growth of moss. Used rating 

curve which is well defined between 5 and 970 second-feet, and several curves 

parallel thereto. Records from water-stage recorder available only subsequent to April 25; staff gage readings used during remainder of year. Staff 

gage read to hundredths usually once daily, except during winter months 

when only occasional readings were obtained. Daily discharge ascertained 

by applying mean daily gage height to rating table except for periods of 

shifting control and estimation as noted in footnote to daily^discharge table. 

For period when water-stage recorder was in operation daily gage heights 

obtained by inspection of recorder graph. Records good.

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

76 SURFACE WATER SUPPLY, 1921,' PART XII B

BLACKFOOT RIVER NEAR SHELLEY, IDAHO

LOCATION. In sec. 7, T. 2 S., R. 38 E., Bingham County, 1J^ miles above mouth 

of canyon, 3 miles "above N. A. Just's ranch, 10 miles southeast of Shelley, 

Bingham County, and 18 miles northeast of Blackfoot. Below all important tributaries.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. June 26,1909, to September 30, 1921. From March 23, 

1903, to December 31, 1909, records were obtained near Presto, about 5 

miles below site of present station. No tributaries enter between the two 

sites, but during the irrigation season several canals divert probably 50 

second-feet.

GAGE. Friez water-stage recorder on right bank. Observer, 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, 6.07 feet at 9 p. m. May 18 (discharge, 1,670 second-feet); minimum stage, 3.03 feet at 10 p. m. November 28 (discharge, approximately 17 

second-feet).

1909-1921: Maximum stage recorded that of May 18, 1921; minimum 

stage, 2.83 feet at midnight January 23, 1919 when ice jam above station 

 caused temporary drop in stage (discharge, about 15 second-feet).

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. No noteworthy diversions are made from river or tributaries 

above station.

REGULATION. Flow regulated largely by storage in the Blackfoot-Marsh reservoir of United States Indian Service, about 40 miles upstream.

ACCURACY. Stage-discharge relation permanent except as affected by ice. Rating curve well denned for open-channel conditions. Operation of waterstage recorder fairly satisfactory except during winter period, when 

occasional staff readings were secured. Daily discharge ascertained by 

applying to rating table mean daily gage height obtained by inspecting 

recorder graph, except as noted in footnote to daily-discharge table. 

Records good.

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

County.

JDBAINAGE ABEA. Not measured.

RECOEDS AVAILABLE. July 27, 1913, to September 30,1921.
SURFACE WATEB SUPPLY, 1921, PAST XII B

GAGE. Inclined staff on right bank half a mile south of the Kofoed ranch 

house. Observer, O. L. Kofoed.

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

wading.

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

same material, fairly permanent. One channel at all stages. Banks covered with heavy growth of brush and willows which may affect stagedischarge relation at high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during period May 7 to 

September 30, 9.60 feet at 12.30 p. m. May 21 (discharge, 868 second-feet)*; 

minimum flow, zero June 12-14.

1913-1921: Maximum stage recorded that of May 21, 1921; minimum 

flow recorded as zero on numerous days in 1919-1921.

JCE. No records obtained during winter.

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

Blackfoot, several smaller diversions also made near Blackfoot.

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

the United States Indian Service, and by manipulation of canal head gates 

above station.

ACCURACY. Stage-discharge relation permanent during peiiod. Standard rating curve well defined between 95 and 710 second-feet. Gage read to hundredths or quarter-tenths daily; diurnal changes in stage caused by regulation are often source of error. Daily discharge ascertained by applying 

gage height to rating table or as noted in footnote to daily-discharge table; 

Records fair.

SAND CHEEK NEAK 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 September 30, 1921.

GAGE. Vertical staff on left bank on upstream side of highway bridge; read by 

P. W. Wernette. Prior to May 17, 1917, vertical staff on left bank, 300 feet 

9 upstream.

DISCHARGE MEASUREMENTS. Made from highway bridge or from small flume 

crossing creek 50 feet downstream or by wading.

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

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

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

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.28 feet at 

4 p. m. May 21 (discharge, 258 second-feet); creek reported dry June 5-8 

and 11-13.

1916-1921: Maximum stage recorded, 4.34 feet at 7 a. m. on April 3, 1919 

(discharge, 348 second-feet); minimum flow zero on days when regulation 

head gates were closed.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. None between Idaho (Government) canal crossing and station.

REGULATION. Idaho (Government) canal which crosses the creek 400 feet above 

the station receives the entire flow of creek as tributary and regulates flow 

returned to creek below by means of head gates. Above this point the 

creek channel is utilized as a waste ditch for numerous canal systems.

ACCURACY. Stage-discharge relation changed during winter; affected by ice 

December 14 to March 8. Two well-defined rating curves used. Gage read 

to half-tenths once daily. Daily discharge ascertained by applying mean 

daily gage height to rating tables except as noted in footnote to daily discharge table. Records good for open-channel periods.

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 September 30, 1921.

GAGE. Stevens eight-day recorder on right bank installed July 14, 1921; referred 

to inclined staff on right bank near center of concrete rating section; read 

by ditch rider for United States Indian Service. Bristol water-stage recorder at same site, datum 1.53 feet lower, used from 1912 to 1914.

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 

a 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 causes several changes in stagedischarge relation during each season.

EXTREMES OF DISCHARGE. Maximum discharge recorded during period, 346 

second-feet June 26; canal dry during various periods in winter season.

1912-1921: Maximum discharge recorded on August 2, 1920, 412 secondfeet; canal reported dry on numerous dates.

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

times for use of stock, but head gates are closed during greater part of 

winter.

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

the 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 immediately below gage, by variable conditions 

at control cheek and by growth of aquatic vegetation. Standard rating 

curves fairly well defined; several parallel curves used. Operation of waterstage recorder satisfactory July 14 to August 25 and September 1 to 29. 

Staff gage read to hundredths twice daily during remaining periods. Daily 

discharge ascertained by applying to rating tables mean staff gage reading 

or mean daily gage height obtained by inspecting recorder graph. Records 

good.

Fort Hall lower canal diverts water from left bank of Blaekfoot River in sec. 

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

LITTLE LOST RIVER AT RAYMOND RANCH, NEAR EOWE, IDAHO

LOCATION. In sec. 29, T. 10 N., R. 27 E., 100 feet above wagon bridge at 

Raymond ranch, l^J miles above Wet Creek and 32 miles northwest of 

Howe, Butte County.

DRAINAGE AEEA. Not measured.

RECORDS AVAILABLE. April 13 to September 30, 1921. From August 28, 1910, 

to October 3, 1913, records were collected at station designated as "Little 

Lost River near Glyde, Idaho,"1 'about 2% miles upstream in sec. 18, T. 10 

N., R. 27 E.

GAGE. Vertical staff on left bank; read by Mrs. Nelle Raymond.

DISCHARGE MEASUREMENTS. Made from wagon bridge below gage 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 

backwater from bridge and channel obstruction below at high stages. Banks 

are overflowed during extreme high water.

EXTREMES OF DISCHARGE. Maximum stage recorded during period April 13 to 

September 30, 3.73 feet June 5 (discharge, 159 second-feet). Some time 

between June 7 and 29 when gage was not read, the stage, according to 

water marks on gage, rose to 4.33 feet (discharge, not determined). Minimum stage'recorded, 0.96 foot April 25 (discharge, 20 second-feet).

ICE. Stage-discharge relation not affected by ice during period of reeord.

DIVERSIONS. Several small ranch diversions above and numerous diversions 

for irrigation below. The Blaine CSunty Investment Co. stores and diverts 

water from Dry Creek, a tributary which enters Little Lost River some 

distance above the gage, 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 changed during high water. Rating curve 

used prior to May 16^ defined by two discharge measurements obtained at 

fairly low stages and drawn parallel to later curve. From May 16 to June 

7, when stages were above 2.25 feet on the gage, a backwater correction curve 

was used. Rating curve used during remainder of year well defined between 

30 and 90 second-feet. Gage read to hundredths once daily. Daily discharge determined by applying daily gage height to rating table. Records 

good for discharge below 90 second-feet; others fair.

BIG LOST RIVER AT HOWELL RANCH, NEAR CHILLY, IDAHO

LOCATION. In sec, 30, T. 8 N., R. 21 E., at Hovrell ranch, 12 miles southwest 

of Chilly, Custer County, and 30 miles northwest of Mackay, nearest railroad 

point. This station was formerly described as "Big Lost River near Chilly."

DRAINAGE AREA. Not .measured.

RECORDS AVAILABLE. April 25, 1904, to August 31, 1906; July 1, 1907, to November 14, 1914; May 11, 1920, to September 30, 1921.

GAGE. Friez water-stage recorder installed June 17, 1920, on left bank and referred to outside vertical staff used May ,11 to June 16, 1920; inspected by 

Mrs. John Howell. A vertical staff at same site but at a datum 2.07 feet 

higher was used June 7, 1912, to November 14, 1914. Prior to June 7, 1912, 

a vertical staff on left bank 100 feet below present gage and at a different 

datum was used.

DISCHARGE MEASUREMENTS. Made from cable 50 feet above gage or by wading. Prior to April, 1921, cable was about one-quarter of a mile below gage.

CHANNEL AND CONTROL. Bed composed of sand, gravel, and cobbles. Channel 

straight. Banks covered with brush and subject to overflow at high stages. 

Control composed of gravel and cobbles; likely to shift at high stages.
TffiBUTAEY BASICS 103

EXTREMES OF DISCHARGE.' Maximum stagd during year frca& water^stage *e-. 

corder, 5.94 feet 4 to 8 a: m. June 12 (discharge, 3,500 second-feet); 

minimum stage, 2.70 feet December 23 (measured discharge, 61 second-feet). 

A lower stage and discharge may have occurred during perfod of no record. 

19(04-1921 (not including period of no record; see "Records available"): 

Maximum stage recorded that of June 12, 1921; minimum stage, 1.9 feet 

April 2, 1909 (discharge, 35 second-feet).

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Several small 'diversions above. Prior to relocation of cable the"1 

discharge 6f Hamjnerly ditch, with a capacity of about 2& second-feet, which 

diverted 100 yards above former cable location, was added to measured 

discharges at cable to obtain total flow past gage.

REGULATION. None.

AccuRAsry. Stage-discharge relation not permanent. Rating curve, which is 

well defined between 74 and 3,100 second-feet, and several curves parallel 

thereto were used. Daily discharge ascertained by applying to rating table 

mean daily gage height obtained by inspection of recorder graph. Because 

of uncertainty regarding time of change of stage-discharge relation after 

middle of July,-daily records for this period may be somewhat in error, 

Monthly records good.

BIG LOST RIVER BELOW CHILLY SINKS, NEAR CHtLLY, IDAHO

LOCATION. In sec. 30, T. 8 N., R. 23 E., at State highway bridge just below 

Chilly Sinks, 6 miles above Maekay dam, and 8 miles southeast of Chilly, 

Glister County. Gage is 4 miles below Thousand Spring* Slough and at a 

point where ground water, presumably from Chilly Sinks or "dry beds," 

commences to rise. > > ' :.- -

DRAINAGE AREA. Not measured. n

RECORDS AVAILABLE. May 1 to September 30, 1921.

GAGE. Vertical staff on left bank 25 feet above highway bridge; read by Ed 

Mulligan.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel. Control formed 

by w'eH-defined gravel riffle 150 feet below gage; subject to change at 

high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during period May 1 to 

September 30, 4.57 feet June 12 (discharge, 2,330 second-feet); minimum 

stage, 0.36 foot May 6 (discharge, 3.5 second-feet). A lower stage and discharge may have occurred during period of no record.

ICE. No record.

DIVERSIONS. Numerous irrigation ditches divert above station.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during high water of June 12. 

Two well-defined rating curves used, one applicable May 4 to June 12, theother applicable June 24 to September 27. Gage read to hundredths at infrequent intervals except during May and June when more frequent readings were obtained. Daily discharge ascertained by applying gage height 

to lating table or for days of no record by estimation or interpolation as 

noted in footnote to table of daily discharge. Records prior to July 15, t 

fair; thereafter, good.

COOPEKATI^. Gage-height record aod results of several discharge measurements furnished by water commissioner for Big Lost River.

Big Lost River divides 6 miles above, forming another channel which is locally 

knowngas ( 'back channel" of Big Lost River and parallels the main channel 

oii,;the*iout^west until their waters converge in Mackay reservoir. Water flows 

in; secondary channel during period when Stage in Big Lost River is sufficiently 

high to cross the sinks. These sinks, a part of which are dry usually from 

first part of August until about middle of May,, extend froma point about 7 miles 

above to within 2 miles of gage. To determine total discharge of Big Lost River 

at this point, flow at this station should be combined with that passing gage on 

back channel of Big Lost River (station about 1 mile distant).

BIO LOST RIVER (BACK CHAHHEL) BELOW CHILLY SINKS, NEAR CHILLY.IJJAHO

LOCATION. In sec. 24, T. 8 N., R. 22 E., at State highway bridge 7 miles above 

Mackay dam, 7 miles southeast of Chilly, Ouster County, and 11, miles 

northwest of Mackay. '

DKAINAGE AREA. Not measured.

RECORDS AVAILABLE. May I to October 31, 1921, when station was discontinued. '

GAGE. Vertical staff fastened to- tree on right bank, installed June 9, 10 feet 

above hig&way bridge. Batfum of gage raised 2 feet July 12, 1921; readings subie^uent to June 9 corrected to new datum. Original gage which 

was washed out June 7, 1921, was a vertical staff installed May 12, 1921, 

at same location but at different datum. Gage read by Ed Mulligan.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wad|ng.

CHANNEL AND CONTROL. Bed composed of sand and gravel. Control formed" 

by gravel riffle located a short distance below; subject to change at high 

stages. Point of zero flow at gage height 0.80 foot ±0.05 foot as determined 

September 5, 1921.

EXTREMES OF DISCHARGE. Maximum stage recorded May 1 to October 31, 4.10 

feet June 13 (discharge, 383 seeoncj-feet); channel reported dry May 1-11.

ICE. No record.

DIVERSIONS. A number of ranch diversions for irrigation above.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Two rating cur-ves used/ 

one applicable May 12 to June 7 is fairly well defined between 2 and 130 

aeeond-feet, the other applicable June 9 to October 31 is well defined to 310 

second-feet. Gage read to hundredths about once a week except during May 

and June, when more frequent readings were obtained. Daily discharge ascertained by applying gage heights to ?»ting table except for periods indicated 

in footnote to daily-discharge table. Records fair chiefly because of fragmentary gage-height record.

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

Big Ijpst River divides 5 miles abjove Ration, forming this channel, which is locally kj}own as " back channel ' of Big Lost River, and parallels the main channel 

until tfteir waters converge in Mackay rpservoir. During high stages or when 

water flows across Chilly Sinks or dry beds water flows in this channel above 

gage. The greater part of thesfe dry beds, which extend from a point about 6 

miles above to within a short distance of the gage, is dry usually from first part 

of August until about middle of May. To determine total discharge of Big Lost 

River at this point flow at this station should be combined with that passing 

gage on main channel of Big Lost River below Chilly Sinks (see p. 107).

114 SURFACE WATER SUPPLY, 1921, PART XII B 

MACKAY RESERVOIR NEAR MACK AT, 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, 1921. Records obtained by Utah Construction Co. prior to January 1, 1919, but were not

published by United States Geological Survey. 

GAGE. Vertical staff on head-gate tower near right end of dam; read by

W. C. Hooper, employee of the Utah Construction Co. Datum of gage 6,000

feet above sea level. 

EXTREMES OF CONTENTS. Maximum stage recorded during year, 62:58 feet June

23 (contents, 39,150 acre-feet); minimum stage recorded, 7.2 feet October

13 and 14 (contents, 33 acre-feet).

1919-1921: Maximum stage recorded that of June 23, 1921; minimum

stage, 6.6 feet August 24 to September 2, 1919, when water surface was

below bottom of outlet tunnel. 

COOPBKATION. Records furnished by Utah Construction Co. through water

commissioner of Big Lost River.

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

the Utah Construction Co.'s Carey Act project. About 7,000 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 in 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" 1J^ miles downstream, where favorable rock structure forces underground water to the surface. Additional water also reappears, part of which is 

probably side drainage and 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 MACK AY, 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, 1 J/£ miles below Mackay dam, and 

23^ miles above Mackay, Custer 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, 1921.

GAGE. Friez water-stage recorder on left bank referred to vertical staff, installed May 4, 1920, 40 feet upstream from location of Steveng eight-day 

recorder used January 1, 1919, to May 3, 1920; inspected by employees of 

Utah Construction Co. A vertical staff gage installed January 6, 1912, at 

Oleson suspension bridge 450 feet above present gage, was in use until 

April 28, 1913. From April 29, 1913, to March 15, 1915, records were obtained at what is commonly known as the Streeter gage, a vertical staff 

located 1 mile below present gage. The Streeter ditch diverts water between 

these two points.

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

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

of moss at times affects stage-discharge relation.

EXTREMES OF DISCHARGE, Maximum stage recorded during year, 5.79 feet June 

10 (discharge, 2,090 second-feet); minimum stage, 1.08 feet October 20 (discharge, 50 second-feet).

1903-1921 (not including period of no record, see "Records available"): 

Maximum stage recorded that of June 10, 1921; minimum stage recorded, 

0.36 foot March 26-28,1914 (discharge, 41 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. N'umerous diversioas above Maekay reservoir, but Sharp ditch is 

only diversion between gage and reservoir.
116 SURFACE WAITER SUPPLY, WZL, PART XII B

REGULATION. Flow past gage is, regulated by operation of> gated in Macks$ 

dam. Prior to 1917 regulation from- storage above was practically negligible.

ACCUBACY. Stage-discharge relation shifts within fairly well defined limits*. 

Two well-defined rating curves and several curves parallel thereto were used^ 

Changes in stage-discharge relation werei ascertained by merins of numerous 

discharge measurements and application of rating determined accordingly. 

Daily discharge ascertained by applying to rating table mean daily gage 

height determined by inspection of recorder graph or by shifting-control 

method as noted in footnote to daily discharge table. Records good.

COOPERATION, Gage-height record furnished by Utah Construction Co., and 

several discharge measurements furnished by water commissioner for Big 

Lost River.

7^ miles northwest of Mackay, Custer County.

DRAINAGE ABBA. Not measured.

RECORDS AVAILABLE. May 1, 1919, to September 30, 1921. - '.'.'..

GAGE. ' Vertical staff on right bank; read by employees of the Utah Construction Co. Prior to May 3, 1920, a vertical staff at about same datum and 

located on right bank 100 feet above present gage was used. .......

DISCHARGE IWEASUREMENTS. Made by wading or from suspension bridge 125 

feet above gage.

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

all stages. Banks steep and covered with brush. Stage-discharge relation' 

affected by growth of mosp.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.25 feet June 

10 (discharge, 200 second-feet); mean discharge for period June 11-16 estimated at 215 second-feet. Minimum stage, 1.38 feet April 28 (discharge, 14 

second-feet). Actual maximum and minimum flow no doubt .occurred o.n 

days of no record.

1919-1921: Maximum stage recorded that of June 10, 1921; minimum 

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

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Natural flow practically all diverted during irrigation season. 

Flow during summer represents return flow from irrigation above. Entire 

flow stored in Mackay reservoir.

REGULATION. None.

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

and brush along banks. Gage read to hundredths once a week except during 

irrigation season when more frequent readings were obtained. Upon basis 

of frequent discharge measurements shifting-control methdd was used 

throughout the year. For days of no record discharge estimated or 

interpolated by comparison with record at station on west channel of Warm 

Spring Creek. Records fair, chiefly on account of numerous breaks in record 

and because of constantly changing channel conditions.

COOPERATION. Gage-height record furnished by Utah Construction Co. Several 

discharge measurements furnished by water commissioner for Big Lost 

River.

DITCH NEAR MACKAY, IDAHO

LOCATION. In sec. 12, T. 7 N., R. 23 E., 250 feet below head of ditch, half a 

mile below Mackay reservoir, and 3J^ miles northwest of Mackay, Ouster 

County.

RECORDS AVAILABLE. June 6, 1912, to October 24, 1914, and March 24, 1919, 

to September 30,1921.

GAGE. Vertical staff on right bank installed April 20, 1920; read during irrigation season by water master or employees of Utah Construction Co. From 

March 24, 1919, to April 20, 1920, a temporary vertical staff on left bank 

100 feet above present gage was used. Gage used June 6, 1912, to June 

25, 1913, was a staff on flume 40 feet below head gates, and gage used June 

26 to October 24, 1914, was vertical staff at the same site as present gage. 

Relation between present and former gages not determined.

DISCHARGE MEASUREMENTS. Made from footbridge or by wading.

CHANNEL AND CONTROL. Control composed of gravel and sand and is poorly 

denned. Stage-discharge relation affected at times by moss and weeds in 

channel.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.50 feet 

June 23 (discharge, 42 second-feet); canal reported dry during winter and 

on other days during season when water was shut off.

1912-1921 (not including period of no record; see "Records available"): 

Maximum discharge recorded that of June 23, 1921; ditch reported dry 

during winter and on other days when water is shut off.

ICE. None. Winter flow presumably derived from leakage through head gates,.

DIVERSIONS. Station is above all points of diversion.

REGULATION. Flow controlled by head gate and by a small wasteway above 

gage.

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

Standard rating curve, which is well denned between 5 and 40 second-feet 

and several curves parallel thereto were used. Gage read to hundredths 

once daily May 10 to August 24 and at irregular intervals during remainder of year. Daily discharge .ascertained by applying daily gage height to 

rating table or by shifting-control method during periods of change in 

rating as noted in footnote to daily-discharge table. Daily discharge estimated and interpolated for periods of no record (see footnote to table of 

daily discharge). Records good.

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

Sharp ditch diverts from east side of Big Lost River sec. 12, T. 7 N., R. 23 

E., 1 mile above heading of Streeter ditch and half a mile below Mackay reservoir. The water is used for irrigation on land northwest of Mackay and 

above Streeter ditch.

GOOSE CREEK ABOVE TRAPPER CREEK, NEAR OAKLEY, IDAHO

LOCATION. In sec. 13, T. 15 S., R. 21 E., 5 miles above Trapper Creek and 10, 

miles south of Oakley, Cassia County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 29, 1911, to September 30, 1916; March 27, 1919, 

to September 30, 1921.

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

Oakley Canal Co. Datum unchanged since August 29, 1912. Gage used 

prior to flood of July 30, 1912, was on right bank 200 feet downstream and 

at a different datum.

DISCHARGE MEASUREMENTS. Made from cable 250 fe,et above gage. ,

CHANNEL AND CONTROL. Bed composed of rock, overlain with mud and silt. 

Control of same material, subject to change. Banks are high and not likely 

to be overflowed. Point of zero flow determined on July 31, 1915, at gage 

height 0.9 foot.

EXTREMES OP DISCHARGE. Maximum stage during year from water-stage recorder, 5.23 feet, at 9 a. m. May 18 (discharge, 670 second-feet); minimum 

stage, 1.64 feet at 8 a. m. November 30 (discharge, 9.7 second-feet). Both 

higher and lower stages no doubt occurred during period of no record. 

. 1911-1916; 1919-1921: Maximum stage recorded that of May 18, 1921; 

minimum stage, 1.19 feet at 9 a. m. August 13, 1915 (discharge, 1.1 secondfeet).

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

DIVERSIONS. A number of small Canals and ditches divert above station chiefly 

for irrigation of lands belonging to the Utah Construction Co.

REGULATION. None except that due to diversions.

ACCURACY. Stage-discharge relation not permanent. Two rating curves, which 

are well defined to 130 second-feet and fairly well defined above, and curves 

parallel thereto based on frequent discharge measurements were used during 

the year. Operation of water-stage recorder not entirely satisfactory, because of faulty operation of inlet pipe. Daily discharge ascertained by 

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

recorder graph or by shifting-control method as noted in footnote to daily 

discharge table. Records good except for possible inaccuracy due to faulty 

operation of inlet pipe.

COOPERATION. Gage-height record furnished by Oakley Canal Co.

: TRAPPER CREEK NEAR OAKLEY, IDAHO

LOCATION. In sec. 33, T. 14 S., R. 21 E., 1^ miles above Nelson ranch, 1 mile 

from east boundary of Minidoka National Forest, 5 miles above Oakley dam, 

and 9 miles southwest of Oakley, Cassia County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May'1, 191.1, to September 30, 1916; March 28, 1919, to 

September 30, 1921.

GAGE. Friez water-stage recorder on left bank 1 mile west of east boundary of 

Minidoka National Forest installed April 8, 1913; inspected by employees 

of Oakley Canal Co. From May 1, 1911, to August 27, 1912, a Lietz waterstage recorder was used half a mile downstream and at a different datum; 

from August 28, 1912, to April 7, 1913, fragmentary records were obtained 

from a staff gage opposite Nelson's house IJxJ miles below present installation.

DISCHARGE MEASUREMENTS. Made by wading. Flow at gage augmented about 

3 second-feet during summer of 1921 by drilling two artesian wells 1 mile 

above gage.

CHANNEL AND CONTROL. Bed composed of small boulders and coarse gravel; 

control shifting. Banks brushy and not likely to be overflowed.

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

recorder, 3.44 feet May 28 and June 8 (discharge, 98 second-feet); minimum 

stage, 1.99 feet October 1-6 (discharge, 9.6 second-feet). A lower stage 

and discharge may have occurred during a period of no record.

1911-1916; 1919-1921: Maximum stage recorded that of May 28 and 

June 8,1921; minimum stage probably occurs in winter when stage-discharge 

relation is affected by ice.

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

DIVERSIONS. No diversions of consequence above station.

REGULATION. None.

ACCURACY. Stage-discharge relation changed due to collection of brush and 

debris on control. Two fairly well defined curves and curves parallel thereto, 

were used. Operation of water-stage recorder not satisfactory at times. 

Daily discharge ascertained by applying to rating table mean daily gage 

height obtained by ihspection of recorder graph, except as noted in footnote 

to daily discharge table. Records fair except for October and November, 

which are good.

COOPERATION. Gage-height record furnished by Oakley Canal Co.

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, 1921.

GAGE. Stevens eight-day water-stage recorder on right bank, referred to staff 

in float well; installed April 1, 1918; inspected by McConnel and Grose. 

Staff gage attached to left abutment of old highway bridge 100 yards 

upstream used prior to that time. A slide gage and a Lietz water-stage

^ recorder at same site and datum were used periodically 1911-1913. New 

datum April 1, 1918.

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 mean discharge, 3,200 second-feet July 

5-7 and 29-31. Canal dry October 1-7, March 30, and April 1.

1909-1921: Maximum mean discharge that of July 5-7 and 29-31, 1921. 

Minimum flow, zero at 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; several parallel curves used. Operation of water-stage recorder satisfactory April 21 to 

September 30; staff gage read to hundredths once daily November 1 to 

April 2 and twice daily for remainder of year. Daily discharge obtained by 

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

or by inspecting recorder graph; also by shifting-control method or as noted 

in footnote to daily discharge table. Records good October to March; 

excellent April to September.

COOPERATION. Gage-height record and 17 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.

SOUTH SIDE TWIN FALLS CANAL AT MILNER, IDAHO

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

below head gates at Milner, in Twin Falls County. 

RECOBDS AVAILABLE. May 10, 1909, to September 30, 1921.
TRIBUTARY BASINS 155

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

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

that time for stages above 5.3 feet. Original gage was a vertical staff attached to lower side of highway bridge 100 feet downstream; installed 

May 10, 1909; used for stages below 5.3 feet. The two gages read practically the same, although datum of upstream gage is 0.1 foot higher. 

Observer, W. N. McConnel.

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

CHANNEL AND CONTROL. Channel at gage blasted out of rock; practically 

permanent. Occasionally slight changes in control are due to deposition of 

silt.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 10.62 feet at 

noon June 19 (discharge, 3,640 second-feet); minimum stage recorded, 1.32 

feet at 10 a. m. on March 13, waste gates open (discharge, 35 secondfeet).

1909-1921: Maximum discharge, 4,600 second-feet August 12, 1918; 

minimum stage, 0.76 foot on September 20, 1920 (no flow).

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. None above gage and none of consequence for several miles 

below.

REGULATION. Flow regulated by head gates.

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

6 to February 19. Two well-defined rating curves used. Gage read twice 

daily to hundredths December 6-31 and May 24-28. Operation of waterstage recorder satisfactory for remainder of year. Daily discharge ascertained by applying to rating table mean daily gage height obtained by 

inspection of recorder graph or from staff gage readings, except as noted in 

footnote to daily discharge table. Records excellent except December to 

February, for which they are good.

COOPERATION. Gage-height record and 26 discharge measurements furnished 

by Twin Falls Canal Co.

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

at the Milner dam and furnishes water for stock and irrigation on about 

200,000 acres of land near Twin Falls. The distribution system comprises 

about 110 miles of main canal and 590 miles of laterals.

166 SURFACE WATER SUPPLY, 1921, PART XII B

SALMON FALLS CREEK NEAR SAN JACINTO, NEV. '

LOCATION. In sec. 23, T. '47 N., R. 64 E., in canyon 200 yards below county 

highway bridge, 250 yards below mouth of Shoshone Creek, and 5 miles 

north of San Jacinto, Elko County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 17, 1909, to September 30, 1916, and October 

1, 1918, to September 30, 1921.

GAGE. Barrett and Lawrence water-stage recorder installed on right bank November 20, 1911; inspected by employees of Salmon River Canal Co. Original gage used prior to June 30, 1910, was a vertical staff on right bank a 

short distance upstream and at different datum. July 1,1910, to November 

19, 1911, record obtained from Friez recorder at present location and 

datum.

DISCHARGE MEASUREMENTS. Made from cable 20 feet below gage or by wading.

CHANNEL AND CONTROL. Bed composed of gravel; somewhat shifting. No welldefined control. Left bank is subject to overflow. Stage of zero flow determined August 11, 1921, gage height 1.66 feet ±0.05 foot.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage recorder, 7.00 feet 8 a. m. to 1 p. m. May 8 (discharge, 1,170 second-feet); 

a higher stage and discharge no doubt occurred during period of no record. 

Minimum stage, 2.56 feet October 2 (discharge, 25 second-feet).

1909-1916; 1919-1921: Maximum stage recorded, 7.5 feet May 22, 1912 

(discharge, 1,280 second-feet); minimum stage, 2.28 feet July 25, 1919 

(discharge, 10 second-feet).

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

Canal Co., which forms a reservoir having a capacity of approximately 

180,000 acre-feet, is 15 miles below station.

ACCURACY. Stage-discharge relation not permanent. Two rating curves used; 

one applicable October 1 to' February 14 is well defined between 10 and 600 

second-feet, the other applicable February 20 to September 30 is well defined 

between 30 and 950 second-feet. Because of inaccessibility of station several breaks occurred in gage-height record. Daily discharge ascertained by 

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

recorder graph. Records good.

COOPERATION. Gage-height record furnished by Salmon River Canal Co. *

and cobbles along right bank; shifting.

EXTREMES or DISCHARGE. Maximum stage recorded during year and for period 

of record in 1920 and 1921, 4.50 feet June 11-13, 1921 (discharge, 2}100 

second-feet); minimum stage, 0.21 foot November 6, 1920 (discharge, 80 

second-feet). A lower stage and discharge may have occurred during period 

of no record.

ICE. No record.

DIVERSIONS. Several small ranch diversions above and below gage.

REGULATION. None except that due to diversions.

ACCURACY. Stage-discharge relation not permanent. Curve well defined and 

curve parallel thereto used Octob'er 1 to May 10. Fairly well-defined curve 

used for remainder of year. Gage read to hundredths twice daily. Gageheight record not entirely satisfactory because observer at times read gage 

slightly high. Daily discharge ascertained by applying mean daily gage 

height to rating table, or by shifting-control methods. Records fair.

COOPERATION. Results of several discharge measurements furnished by water 

master for Big Wood and Little Wood rivers.

BIG WOOD RIVER AT HAILEY, IDAHO

LOCATION. In sec. 9, T. 2 N., R. 18 E., at steel highway bridge one-fourth 

mile southwest of Hailey, Blaine County.

DEAINAGE ABEA. 640 square miles (measured on topographic maps).

RECORDS AVAILABLE. June 11, 1915, to September 30, 1921.

GAGE. Vertical staff set in concrete on right bank, installed April 6, 1920, at a 

datum 1 foot lower than previous gage; used April 8, 1920, to September 

30, 1921. From April 3, 1917, to April 7, 1920, a vertical staff in two sections was used; high-water section on left bank and low-water section at 

different datum on right bank; all readings on low-water staff corrected to 

datum of high-water section. Prior to April 3, 1917, an inverted stadia 

board attached to pile near left bank was used. Zero gage height on vertical 

staff used April 3, 1917. to April 7, 1920, was at gage height 6.00 feet on 

inverted stadia board gage. Gage read by employees of United States 

Forest Seryice.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

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

Channel fairly straight above and below station. Banks covered with 

light brush; subject to overflow at high stages when river may flow in from 

one to three channels, the number depending on the stage. Low-water 

control formed by sheet piling used to protect a water may# that crosses 

the river; high-water control subject to shift.

EXTREMES OF DISCHAKGE. Maximum stage recorded during year, 5.70 feet June 

12 (discharge, 3,560 second-feet); minimum stage, 0.51 foot January 30 

(discharge, estimated, 0.4 second-foot).

1915-1921: Maximum stage recorded, that of June 12, 1921; minimum 

stage that of January 30, 1921.

ICE. Stage-discharge relation slightly affected by ice at times.

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 the station. Records 

of the flow of Big Wood Slough have been obtained (see p. 190), and the total 

flow of Big Wood River is represented by amount of water passing both 

stations (pp. 173-4).

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.
172 SURFACE WATER SUPPLY, 1921, PART XII B

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

December 9 to March 4. Three well-defined rating curves and curves parallel 

thereto used during the year. Gage read to hundredths once daily. Daily 

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

good except for discharge above 2,000 second-feet, for which they are fair.

COOPERATION. Gage-height record prior to July 1, 1921, furnished by Idaho 

Irrigation Co. Water master for Big Wood and Little Wood rivers 

furnished results of measurements made by him.

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

published herewith.

ranch, l}£ miles above flow line of Magic reservoir, and 10 miles southwest 

of Bellevue, Blaine County. Camas Creek enters reservoir 3 miles below 

station.

DBAINAGE AREA. 823 square miles (measured on topographic and Land Office 

maps).

RECORDS AVAILABLE. July 6,1911, to September 30,1921.

GAGE. Gurley water-stage! recorder on right bank installed July 8,1921, three- 1 

eighths mile above former location which was used prior to June 16, 1921, 

when gage was washed out by high water. Datum at new location not 

determined. Inspected by assistants of Wood River water master. For 

gages used prior to June 16,1921, see Water-Supply Paper 513.

DISCHARGE MEASUREMENTS. Made from cable 30 feet above gage or by wading.

CHANNEL AND CONTROL. Bed composed of coarse gravel. Control of same 

material; shifts occasionally. Both banks are clean and may be overflowed 

at extremely high stages.

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

recorder, 6.07 feet at 7 p. m. June 16 (discharge, 3,660 second-feet); a 

. higher stage and discharge no doubt occurred during period of no record 

after gage had been washed out; minimum stage, 0.71 foot at 6 p. m. October 6 

(discharge, 44 second-feet). A lower discharge may have occurred during 

period of no record.

1911-1921: Maximum stage recorded, that of June 16, 1921; minimum

BIG WOOD RIVER BELOW MAGIC DAM, NEAR RICHFIELD, IDAHO

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

dam of Big Wood Canal Co. (formerly Idaho Irrigation Co.) and 18 miles 

northwest of Richfield, Lincoln County. No tributaries between dam and 

station.

DRAINAGE ABBA. Not measured.

RECORDS AVAILABLE. April 19, 1911, to September 30, 1921.

GAQE. Gurley water-stage recorder on right bank installed April 20, 1916, to 

replace former Lallie recorder at same location. Gage inspected by Ed Dayton and G. T. Parkinson. Datum presumably unchanged since establishment of station,

DISCHARGE MEASUREMENTS. Made from cable 10 feet above gage or by wading.

CHANNEL AND CONTROL. Bed composed of clean coarse gravel and small boulders. Control of same material; somewhat shifting. Point of zero flow 

determined September 17, 1921, at gage height 0.85 foot ±0.05 foot.

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

recorder, 9.18 feet at 8 p. m. June 12 (discharge, 4,240 second-feet); minimum stage, 1.20 feet October 11-23 (discharge, 1.9 second-feet).

1911-1921: Maximum stage recorded, 9.2 feet May 18,1911 (discharge, 

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

ICE. Stage-discharge relation seldom affected by ice.

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

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

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

diversion by the company is the Richfield canal, about 2 miles below.

REGULATION. Flow past station is regulated by gates in outlet tunnel at Magic, 

dam.

ACCURACY. Stage-discharge relation practically permanent. Rating curve 

which is well defined up to 3,600 second-feet, and curve parallel thereto used 

during the year. Daily discharge ascertained by applying to rating table 

mean daily gage height obtained by inspection of recorder graph, or for days 

when fluctuations were extreme, discharge ascertained by averaging results 

obtained by applying gage height for hourly or other regular interval to the 

rating table. Records good.

COOPERATION. Gage-height record and most of discharge measurements furnished by water maste for Big Wood and Little Wood rivers.

DISCHARGE MEASUREMENTS. Made by wading or from cable located 300 feet 

below gage.

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

Control formed by lava-rock riffle about 100 feet below gage; fairly permanent. One channel at all stages. Point of zero flow occurs at a gage height 

of approximately 4.50 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during period April 1 to 

September 30, 12.79 feet June 13 (discharge, 3,330 second-feet); channel 

reported dry prior to April 21 and subsequent to September 16.

ICE. No records; channel practically dry.

DIVERSIONS. Numerous diversions for irrigation made above and below station. 

Richfield canal of Big Wood Canal Co. (operating Idaho Irrigation Co.'s, 

project) is main diversion between station and Magic dam.

REGULATION. Flow regulated by operation of head gates at Magic dam about 

13 miles above, except when water is wasted over spillway.

ACCURACY. Stage-discharge relation probably permanent. Rating curve which 

is well defined between 100 and 1,500 second-feet and curve parallel thereto 

used during the period. Gage read to hundredths twice daily. Daily discharge ascertained by applying mean daily gage height to rating table; 

shifting-control method used June 4-13. Records good.

COOPERATION. Gage-height record and discharge measurements furnished by 

water master for Big Wood and Little Wood rivers.

BIG WOOD SLOTTG5 AT HAILEY, IDAHO .,

LOCATION. In sec. 9, T. 2 N., R. 18 E., at highway bridge one-eighth of a mile 

 northeast of steel highway bridge across Big Wood River and one-eighth 6f 

a mile southwest of Hailey, Blaine County.

RECORDS AVAILABLE. June 11, 1915, to September 30, 1921.

GAGE. Vertical staff spiked to downstream side of highway bridge, installed 

April 4, 1917; read by employees of United States Forest Service. Prior to

-.. - . April 4, 1917, an inverted stadia board at same location was used; 2.0 foot? 

mark on stadia board corresponds to 2.0-footmark on present gage.

DISCHARGE MEASUREMENTS. Made from footbridge or by wading. ;

CHANNEL AND CONTROL. Bed composed of sand and gravel. Banks covered with 

brash anjd siiifjelct to overflow. One channel at all stages. Control is top 

of a wood-stave water pipe, laid in bed of stream about 15 feet below gage» 

= overlaid with gravel and sand; subject to shift.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.0 feet June 

6 (discharge, 419 second-feet); minimum stage, 1.58 feet October 3 (discharge, 66 second-feet).

1915-1921: Maximum stage recorded that of June 6, 1921; minimum discharge, 0.9 second-foot March 21-24, 1919.

ICE. Stage-discharge relation not seriously 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 diurnal fluctuation. 

The main river is affected inversely by any such regulation, so the accuracy 

of the summation of the two records is presumably affected only slightly by 

this factor.

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

rating curves used, one applicable October 1 to November 18; the other 

applicable November 20 to September 12. Gage read to hundredths once 

daily. Gage-height record reliable except as noted in footnote to daily 

discharge table. Daily discharge ascertained by applying daily gage height 

to rating table. Records fair,

COOPERATION. Gage-height record prior to July 1 furnished by Idaho Irrigation 

Co. Several discharge measurements furnished by water master for Big 

Wood and Little Wood rivers.
BASICS

Big Wood Siougha^a, natural channel of Big Wood Ri^er that is utiliitod aMo 

as a tailrace for the Hailey power plant. Record from this station represents a 

portion of the natural flow~of Big Wood River arid taken in conjunction with 

the record at ttfe Hear4>y station on the main river (see p. 172) will show the 

entire flow of the river at this point. For record of the combined flow of Big 

Wood River airid Big W«od Slough see pages 173 and 174.

CAMAS CREEK NEAR BLAINE, IDAHO

LOCATION. In sec. 15, T. 1 S., R. 16 E., 500 feet below sheep bridge, a quarter 

of a mile north of Macon siding on Hill City branch of Oregon Short Line 

Railroad, 1^ miles-belew railroad crossing, 2*4 miles .above backwater of 

Magic reservoir, and 4 miles southeast of Blaine, Camas County. No 

tributaries or diversions between station and Magic reservoir.

DRAINAGE AREA.-' Not measured.

RECORDS AVAILABLE. May 9, 1912, to September 30, 1921. Results of discharge measurements made in 1911 by Idaho Irrigation Co. are also available.

GAGE. Gurley water-stage recorder on left bank; installed June 1,1916. Lallie 

water-stage recorder at same location used prior to 1916. Location and 

datum of gage unchanged since 1912. Gage inspected by deputy water 

masters.

DISCHARGE MEASUREMENTS. Made from sheep bridge or by wading.

CHANNEL AND CONTROL. Bed of stream is rocky but control somewhat shifting. 

One channel at all stages. Point of zero flow determined August 24, 1921, 

as at gage heights 0.52 foot ±0.05 foot.

EXTREMES OP DISCHARGE. Maximum stage during period June 1 to September 

30 from water-stage recorder, 5.15 feet at 4 a. m. June 3 (discharge, 870 

second-feet); discharge June 1 estimated mean for day, 920 second-feet. 

Minimum stage, 1.12 feet August 30, September 13,14 (discharge, 4.4 secondfeet) . A lower stage and discharge probably occurred during period of no 

record.

1911-1921: Maximum stage recorded, 10.76 feet April 12, 1916 (measured 

discharge, 5,240 second-feet); minimum stage, 0.89 foot 4 to 6 p. m. August 

17) 1920 (discharge, 2.3 second-feet). These figures probably do not represent actual extremes.

ICE. Records discontinued during winter.

DIVERSIONS. Many small diversions are made above station, but no data are 

available concerning them.

REGULATION. None.
"TRIBUTARY BASINS

ACCUBACT. Stage-discharge relation not permanent, shifts within fairly well 

defined limits. Rating curve is well defined between 4 and 900 second-feet. 

Daily discharge ascertained by applying to rating table mean daily gage 

height obtained by inspection of recorder graph, except for periods indicated 

in footnote to daily discharge table. Records fair chiefly because of changing 

channel conditions and breaks in gage-height record. '

COOPERATION. Gage-height record and number of discharge measurements 

furnished by water master for Big Wood aiid Little Wood rivers.

JACK CREEK NEAR TTJSCAHORA, NEV.

LOCATION. In sec. 35, T. 42 N., R. 52 E., at R. M. Woodward ranch on ElkoMountain City stage road, 8 miles above confluence with South Fork of

Owyhee River and 12 miles northeast of Tusearora, Elko County. 

DRAINAGE AREA. 31 square miles (measured on United States Forest Service

map).

RECORDS AVAILABLE. May 15, 1913, to September 30, 1921, r 

GAGE. Vertical staff on right bank 500 feet below Woodward's house; read by

R. M. Woodward.

DISCHARGE MEASUREMENTS. Made by wading. 

CHANNEL AND CONTROL. -Bed composed of coarse gravel and small boulders;

shifting. Banks low and lined with willows; subject to overflow at extreme

high stages. 

EXTREMES OF DISCHARGE. Maximum stage recorded, 3.00 feet at 6 p. m. May

18 (discharge, 372 second-feet); minimum stage, 0.18 foot September 11-27

(discharge, 2 second-feet). , ,, , ,

1913-1920: Maximum stage recorded, 3.6 feet at 6 p. m. May 14, 1917

(discharge, 465 second-feet); minimum discharge, 0.6 second-foot September

2 and 3, 1918.

ICE. Stage-discharge relation usually affected by ice each winter. - 

DIVERSIONS. Small ditches on Woodward ranch practically only diversions

above station. Have little effect on flow except during August and September.

REGULATION. None.

ACCURACY. Stage-discharge relation changed slightly during high water; affected 

, by ice December 7-27, January 12-18, and February 14-22. Two rating-curves

used, each fairly well defined between 2 and 200 second-feet. Staff gage

read about every other day October to February and August to September.

Daily readings obtained during a considerable part of the other months.

Daily discharge determined by applying to rating tables the staff gage

i'.) readings except during ice-affected periods when mean discharge was esti-

! mated from current-meter measurements, observer's notes, and study of

 climatic records. Discharge for days when gage was not read ^obtained .by

interpolation. Records fair. 

COOPERATION. Gage-height record furnished by R. M. Woodward.

TRIBUTARY BASINS 223 

MOORE CREEK NEAR ARROWROCK. IDAHO

LOCATION. In sec. 21, T. 3 N., R. 4 E., Boise County, a quarter of a mile above 

highway bridge on Boise-Arrowroek road, half a mile above mouth, and 5 

miles southwest of Arrowrock.

DRAINAGE AREA. 426 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 1, 1914, to September 30, 1921 (discharge measurements only, prior to December 1, 1915).

GAGE. Graduations to feet and tenths chiseled on face of rock ledge on left 

bank of stream and marked with white paint; used prior to July 15, 1921. 

Temporary vertical staff at different datum about 700 feet downstream on 

left bank was used thereafter. Gage read by Oliver Call.

DISCHARGE, MEASUREMENTS. Made from highway bridge a quarter of a mile 

below, or by wading.

CHANNEL AND CONTROL. Bed composed of boulders, cobbles, and sand. Control shifts frequently owing to deposition of sand during low stages and 

cutting out during high stages. Stream frequently carries much sand and 

silt as a result of placer operations in Boise basin. One channel at all 

stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 5.5 feet April 

3 (discharge, 2,170 second-feet); minimum stage, 0.60 foot (temporary 

gage) September 1, 2 (discharge, 33 second-feet).

1915-1921: Maximum stage, 6.3 feet April 11, 1916 (discharge, 3,140 

second-feet); minimum stage, 0.60 foot August 17, 21-23, 1920 (discharge, 

17 second-feet).

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

DIVERSIONS. No important diversions above station.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Bed of stream changes 

constantly, but variations in stage-discharge relation not great. Prior to 

July 15 a well-defined standard rating curve, and curves parallel thereto, 

used October 1 to July 15 based on frequent discharge measurements, A 

poorly defined curve, used for temporal y gage July 16 to September 30. 

Shifting-control method used for intervening periods as noted in footnote 

to daily discharge table. On account of rough water, especially at higher 

stages, it is difficult to read gage with refinement. Gage read to half-tenths 

once daily during high water and to hundredths during low-water-period. 

Daily discharge obtained by applying gage height to rating table. Because 

of rapid fluctuations during high-stage period, one daily reading may not 

always be a true index of mean daily flow. Daily discharge may also be 

somewhat in error due to shifting of channel, but monthly summary is good.

COOPERATION. Several discharge measurements made by employees of United 

States Bureau of Reclamation and water master for Boise River.

DIVERSIONS FROM BOISE RIVER, IDAHO

Below mouth of Moore Creek and between gaging stations at Bowling 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 1921. Record of daily diversions subsequent to 1915 is on file in office of Idaho commissioner of reclamation.

MALHEUR RIVER NEAR DREWSEY, OR.EG.

LOCATION. In SW. ^ sec. 32, T. 20 S., R. 36 E., at Drinkwater ranch 2 miles 

below mouth of Otis Creek, 4 miles below Drewsey, Harney County, and 6 

miles above high-water line of Warmsprings reservoir.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. June 1 to December 29, 1920, and April 11 to September 

4, 1921. The records at this station are not directly comparable with 

records at station referred to as Malheur River near Drewsey March 9 to 

September 30, 1914, because of inflow of Griffin, Otis, and Stinking Water 

creeks.

GAGE. Stevens 8-day water-stage recorder on left bank referenced to outside 

staff gage beginning July 14, 1921, inspected by Silas Tillotsen. Staff gage 

read three times a week up to July 5.

DISCHARGE MEASUREMENTS. At low and medium stage made by wading 300 

feet below gage; at high stages made by combining discharge of Malheur 

River at bridge near Drewsey and Otis Creek at bridge near mouth.

CHANNEL AND CONTROL. Bed composed of gravel and sand. Control likely to 

shift. One channel except at extreme high stage when water would overflow left bank.

EXTREMES OF DISCHARGE. Maximum stage recorded during the period ending 

September 4,1921, 5.63 feet at 1 a. m. April 14 (discharge, 2,240 secondfeet); minimum stage recorded, 0.75 foot August 7 (discharge, 7 secondfeet).

1920-1921: Maximum stage recorded that of April, 14, 1921; minimum 

stage recorded, 0.62 foot August 17, 1920 (discharge, 2.6 second-feet).

ICE. Stage-discharge relation not affected by ice during period covered by 

records. 

DIVERSIONS. Several small diversions above station, no diversions around 

station or between station and Warmsprings reservoir.

REGULATION. None.

ACCURACY. Stage-discharge relation practically permanent. Rating curve 

fairly well defined below 1,200 second-feet. Operation of recorder satisfactory except for short periods as noted in footnote to table of daily discharge. 

Daily discharge ascertained by applying to rating table mean daily gage 

height obtained by inspecting recorder graph or weekly gage reading August 2 to September 4. Records good except for periods when discharge was 

estimated or in excess of 1,500 second-feet when they are fair.

232 SURFACE WATER SUPPLY, 1921, PART XII B

MALHETTR RIVER NEAR HOPE, OREG.

LOCATION. In SW. % sec. 5, T. 19 S., R. 43 E., half a mile above intake of 

Vines canal, half a mile above railroad bridge, 15 miles west of Vale, and 6J/2 

miles west of Hope, Malheur County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 30 to October 26,1919; May 5 to September 30,1920; 

fragmentary record during 1921. Station maintained half a mile below 

intake of Vines canal, March 22 to September 30, 1914.

GAGE. Stevens continuous water-stage recorder on left bank, referred to outside staff gage.

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

CHANNEL AND CONTROL. Bed composed of sand, gravel, and boulders; subject to shift at high stages. One channel at all stages.

EXTREMES OP DISCHARGE. Maximum discharge during year estimated as the 

same amount as for the Namorf station, 3,950 second-feet (recorder not 

operating on that date); minimum discharge, estimated as 50 second-feet 

October 1. (Recorder not operating until October 8.)

1919-1921: Maximum discharge, that of 1921; minimum stage from 

water-stage recorder, 0.02 foot from 5-9 p. m. September 2, 1919 (discharge, 

3.5 second-feet).

ICE. No records during winter.

DIVERSIONS. Several small canals divert water above this point.

REGULATION. Flow controlled to a large extent by Warmsprings dam 60 miles 

above.

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

Operation of water-stage recorder unsatisfactory except fqr shoit periods. 

Daily discharge ascertained by applying to rating table mean daily gage 

height determined by inspecting recorder graph. Records good for days 

when gage heights are available.

The record a't this station shows the discharge above the intakes of the canals 

of the Warmsprings Irrigation District. It was used in partly defining and 

checking the rating for the station qn Malheur River at Namorf. Because of 

the numerous breaks in the record, and because the flow at Namorf, except for 

diversions at Harper, is practically the same as that at this station, no attempt 

was made to estimate the discharge for periods of no gage record.

WILLOW CREEK HEAR MALHEUR, OREG.

LOCATION. In sec. 6, T. 14 S., R. 41 E., at Stanfield ranch, half a mile above 

flow line of reservoir No. 3 t>f Willow River Land & Irrigation Co. and 

2J^ miles south of Malheur, Malheur County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. November 20, 1904, to August 14, 1906, March 19, 1910, 

to August 2, 1911, March 27, 1912, to September 30, 1915, and March 1 to 

September 30, 1921.

GAGE. Barrett and Lawrence water-stage recorder on left bank referenced to 

outside vertical staff gage, the zero of gage was set at same level as top of 

low-water section of control; inspected two or three times each week by 

James Minongham.

DISCHARGE MEASUREMENTS. Made from bridge 200 feet below gage or by 

wading.

CHANNEL AND CONTROL. Just below gage is an artificial control of concrete. 

The crest is 2 feet above stream bed, 8 inches wide, inclined toward right 

end 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. Because the cut-off 

wall in bed of stream was not deep enough some water leaked under the 

control. The stream bed is sand and loose gravel.

EXTREMES OP DISCHARGE. Maximum stage recorded during period March 1 to 

September 30, 3.1 feet at midnight March 17 (discharge, 310 second-feet); 

minimum flow estimated by observer as 0.2 second-foot on September 9.

ICE. Stage-discharge relation seriously affected by ice during winter.
234 SURFACE WATER SUPPLY, 1921, PART XII B

DIVERSIONS. Several small diversions above station; reservoir No. 3 just below. 

Eldorado ditch diverted 4,480 acre-feet from tributaries of Burnt River into 

basin of Willow Creek, 25 miles above gaging station, during period April 9 

to September 30.

ACCURACY. Stage-discharge relation permanent except during first period of 

high water March 17-27. Rating curves well defined except one used 

March 17-27. Operation of water-stage recorder satisfactory except for a 

few days. Daily discharge ascertained by applying to rating table mean 

daily gage height obtained by inspecting recorder graph, except March 17-27 

when daily discharge was obtained by applying mean gage height to a curve 

drawn through measurement made March 23 and 24 and parallel to standard 

curve. Records excellent except March 17-27, when they are fair.

NORTH FORK OF PAYETTE RIVER 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 AKEA. 131 square miles (measured on topographic and! Land Office 

maps).

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

September 30, 1921.

GAGE. Inclined staff on left bank installed July 25, 1911; lead by \fernqn Land. 

Original temporary gage, used September 1 to October 8, 1908, was 1 mile 

below site of present gage; permanent vertical staff gage, used until July 25, 

1911, was installed October 14,1908, on left bank 30 feet below present 

site. Gage datum unchanged since October 14, 1908.

DISCHARGE MEASUREMENTS. Made from cable half a mile below gage, from highway bridge at Lardo, or by wading.

CHANNEL AND CONTROL. Bed of stream and control composed of cobbles and 

gravel; slightly shifting. One channel at all stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 7.15 feet June 

9 (discharge, 3,590 second-feet); minimum stage, 1.30 feet July 20 (discharge, 

6 second-feet).

1908-1917; 1919-1921: 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 pfroximity of station to Payette Lake.

DIVERSIONS. None above station.

REGULATION. Flow during July, August, and Septe'mber, partly regulated by installation and later gradual removal of a temporary dam at outlet of Payette 

. Lake a quarter of a mile above.
23S SURFACE WATER SUPPLY, 1921, PAST XII B

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

curves and curves parallel thereto used during the year. Gage read to halftenths once daily. Gage-height record somewhat unreliable during winter and 

discarded entirely for period November 18 to December 4. Daily discharge ascertained by applying daily gage height to rating table except as 

noted in footnote to daily discharge table. Daily discharge considered only 

fair chiefly because of possible inaccuracy of gage-height record; monthly 

summary good.

NORTH FORK OF PAYETTE RIVER AT VAN WYOK, IDAHO

LOCATION. In sec. 26, T. 14 N., R. 3 E., at highway bridge half a mile north 

of Van Wyck, Valley County, and 2 miles northwest of Cascade. Willow 

Creek, a small stream, enters from south half a mile below.

DRAINAGE AREA. 586 square miles (measured on topographic and Land Office 

maps).

RECORDS AVAILABLE. January 1, 1912, to June 30, 1916; June 9, 1920, to September 30, 1921. Gage heights January 1 to August 7, 1912, were derived 

from private records from comparative gage readings; daily discharge not 

determined prior to June 20, 1912. Several discharge measurements made 

during 1919 and spring of 1920.

GAGE. Vertical staff spiked to downstream side of second bridge pier from right 

end of bridge; read by Udell Witchey October 1 to December 6, and L. S. 

Kimball April 7 to Septembei 30. Gage used August 8, 1912, to May 4, 

1913, was a vertical staff at same location, reading 0.6 foot higher than 

present gage.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of rock overlain by sand and gravel; 

control somewhat shifting.

EXTREMES OP DISCHARGE. Maximum stage recorded during the period, 8.6 feet 

May 20 (discharge, 8,700 second-feet); minimum stage, 1.6 feet August 8 

(discharge, 171 second-feet).

1912-1916; 1920-1921: Maximum discharge that of May 20, 1921; minimum stage, 1.70 feet August 20 and 21, 1920 (discharge, 128 second-feet).

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

DIVERSIONS. Practically no diversions are made from main stream above station, 

but numerous diversions for irrigation are made from tributaries.

REGULATION. Flow during July, August, and September partly regulated by installation and later gradual removal of a temporary dam at outlet of Payette Lake 30 miles above.

ACCURACY. Stage-discharge relation changed during high water of May 18. 

Two rating curves used one applicable October 1 to May 17, is fairly well 

defined between 140 and 4,300 second-feet and an extension above; the 

other, applicable May 21 to September 30, is fairly well defined between 190 

and 7,500 second-feet. Gage read to quarter-tenths once daily. Daily discharge ascertained by applying daily gage height to rating table except as 

noted in footnote to daily discharge table. Records fair.

SURFACE WATER StJPPLY, 1921, PART XII B

MIDDLE FORK OF WEISfiR RIVER NEAR MESA, IDAHO

LOCATION. In NW. ^i sec. 10, T. 15 N., R. 1 W., at State highway bridge at 

former post office of Middle Fork, 2 miles above junction with Weiser 

River,. 2^ miles north of Mesa, Adams County, and three-fourths of a mile 

below former gaging station described as " Middle Fork of Weiser .Rivet 

near [or at] Middle Fork, Idaho."

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. August 18,1919j to November 12,1921, when records were 

discontinued. Records are available for station three-fourths of a mile upstream, October 4, 1910, to August 31, 1913.

GAGE. Vertical staff on left bank bolted to tree about 25 feet below highway 

bridge; read by W. J. Evans. Gage at former site, three-fourths of a mile 

upstream, was an inclined staff on right bank.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of gravel. Control formed by welldefined gravel riffle just below gage; shifts at high stages. One channel at all 

stages. Stage of zero flow as determined August 25, 1921, is at gage 

height 1.10 feet, ±O.Q5 foot.

EXTREMES OP DISCHARGE. Maximum stage recorded during period October 1, 

1920, to November 12, 1921, 6.06 feet May 20-22 (discharge, 1,070 secondfeet); minimum stage, 1.70 feet October 19-23, 1921 (discharge, 10 secondfeet).

1919-1921: Maximum stage recorded that of May 20-22, 1921; minimum 

stage, 1,58 feet August 19 to September 1, 1919, and July 24-26, 1920 (discharge, 1.7 second-feet).

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

during winter.

DIVERSIONS.- The principal diversion is Mesa Orchards ditch, which diverts 

about 6^ miles upstream.

REGULATION. None except that due to diversions.

ACCURACY. Stage-discharge relatiofi- not permanent. Rating curve which is 

well defined to 420 second-feet used October 1 to November 6, 1920; curve 

which is well defined between 15 and 300 second-feet and fairly well defined 

above, and a curve parallel thereto, used November 7, 1920, to November 

; :I2, 1921. Gage read to hundredths once daily, gage-height record at times 

is not entirely reliable. Daily discharge ascertained by applying daily gage 

height to rating table; shifting-control method used August 1-12 and 

September 1-8. Records fair chiefly because of possible inaceuracy in gageheight record.

COOPERATION. Gage-height record furnished by Mesa Orchards Co.

LITTLE WEISER RIVER NEAR. CAMBRIDGE, IDAHO , ,.

LOCATION. Near line between sees. 8 and 9, T.vl4 N., R. 2 W., on Gladhart 

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

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

Creek.

DRAINAGE AREA. 187 square miles (measured on topographic maps and United 

States Geological Survey base map of Idaho).

RECORDS AVAILABLE. May 22, 1920, to September 30, 1921.

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

highway bridge; read by Mary M. Lynch and Mrs. W. J. Martin.

DISCHARGE MEASUREMENTS. Made from wooden 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 about 75 feet below gage; subject to 

change during high water. Stage of zero flow at gage height 1.30 feet as 

determined August 25, 1921,

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.70 feet at 

4 p. m. March 18 (estimated discharge, 1,990 second-feet). An estimated 

mean discharge of 2,350 second-feet occurred December 31 when gage was 

submerged. Minimum stage, 1,55 feet August 31 to September 2, 10, 11 

(discharge, 0.6 second-foot).

1920-1921: Maximum discharge that of December .31, 1920; channel 

reported dry August 2 to September 14 and September 17-25, 1920.

ICE. None reported.

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 during high-water period. One 

fairly well defined curve and two curves which are well defined between 

30 and 800 second-feet and curves parallel thereto used during the year. 

Above 800 second-feet curves- are an extension. Gage read to hundredths 

twice daily. Daily discharge ascertained by applying mean daily gage 

height to rating table except as noted in footnote to daily discharge table. 

Records for discharge between 3 and 30 second-feet subject to error because 

of poor definition of rating curve. Records for other discharge up to 800 

second-feet are good, above 800 second-feet, fair.

R. 3 W., at head of flume 150 feet below diversion dam.

RECORDS AVAILABLE. June 23, 1920, to September 30, 1921.

GAGE. Friez water-stage recorder installed September 15, 1921, on left side of 

and 700 feet above end of wooden flume. Prior to September 15, 1921, 

water-stage recorder located 150 feet below head of flume and 3% miles 

above present location. Gage inspected by John R. Scott. Except for small 

leakage between two locations flow is about the same at both points.

DISCHARGE MEASUREMENTS. Made from plank across flume.

CHANNEL AND CONTROL. Section of wooden flume forms control. Zero flow determined for upper location June 25, 1920, as at gage height 0.36 foot. For 

new location, control formed by section of wooden flume and earth section 

of canal below.

EXTREMES OF DISCHARGE. Maximum stage during irrigation season, from waterstage recorder, 1.94 feet July 27-29 (discharge, 69 second-feet); minimum 

stage, 0.97 foot (new datum) September 30 (discharge, 18 second-feet). 

Canal dry during nonirrigation season.

1920-1921: Maximum stage recorded, 2.83 feet at 4 to 8 a. m. July 15 

(discharge, 79 second-feet); canal reported dry during nonirrigation season

ICE. No record. Canal dry except during irrigation season.

DIVERSIONS. None between gage and point of diversion.

REGULATION. Flow controlled by head gates at head of flume.

ACCURACY. For original location of gage, stage-discharge relation changed because of removal of check boards. Rating curves are well defined. For 

period September 16-30 for new location of gage, rating curve which is well 

defined chiefly by 1922 measurements. Daily discharge ascertained by applying to rating table mean daily gage height obtained by inspection of 

recorder graph. Records excellent.

shifts slightly.

EXTREMES OP DISCHARGE. Maximum stage recorded during period, November

21 to September-30, 8.1 feet May 20, 21, 24, and 25 (discharge, 3,010

second-feet); minimum discharge estimated as 1 second-foot August 14-31.

1909-1916; 1920-1921: Maximum stage recorded, that of May 20, 21, 24,

and 25, 1921; stream bed dry in August and September, 1910.

ICE. Stage-discharge relation seriously affected by ice. No ice during period 

of record in 1921.

DIVERSIONS. Water is diverted from Powder River and its tributaries for 

irrigating 72,000 acres of land above this station.

REGTJLAT i ON . None.

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

defined below 2,000 second-feet. Gage read to hundredths once a day.

LOCATION. In see. 6, T. 21 N., R. 22 E., at rear of Rose ranch buildings, 300 

feet below island, just above Lemhi River, and a quarter of a mile, below 

highway bridge at Salmon, Lemhi County.

DRAINAGE AREA. -3,600 square miles (Forest Service records).

RECORDS AVAILABLE. April 25, 1912, to September 30, 1916, and July 6, 1919, 

to September 30, 1921.

GAGE. Inclined staff on left bank installed October 20, 1913; read by-E. A. 

and Viola Renner. Prior to October 20, 1913, gage was an inclined staff 30 

feet upstream. Both gages referred to same datum but present gage reads 

about 0.08 foot lower.'

DISCHARGE MEASUREMENTS. Made from cable 700 feet below gage. ; 

CHANNEL AND CONTROL. Bed composed of rock overlain with sand and gravel. 

Control shifts slightly. One channel at all stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 9,35 feet June 

12 (discharge, 16,400 second-feet); minimum stage, 2.2.,feet, December 17 

and January 11 (discharge, 875 second-feet).

1912-1916; 1919-1921: Maximum stage recorded that of June 12, 1921; 

minimum discharge recorded, 710 second-feet August 30 to September 3, 

December 8 and 9, 1919.

ICE. Stage-discharge relation somewhat affected by ice.

DIVERSIONS. A small ditch diverts from left bank between bridge and gage but 

its maximum capacity is less than 1 per cent of low-water flow. Numerous 

small diversions, principally on tributaries above.

REGULATION. Nese. -----

ACCURACY. Stage-discharge relation not permanent. Two rating curyes were 

used; one, applicable October Ito December 10, is fairly well defined between 

900 and 7,000 Second-feet, the other, applicable December 17 to September 

30, is well defined between 900 and 9,000 second-feet and fairly well defined 

above. Prior to July 20 gage read irregularly, thereafter read to hundredth* 

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

rating table and interpolating and estimating for days of no gage height, as 

noted in footnote to daily discharge table. Records good except for interpolated and estimated periods, for which they are fair.

COOPERATION. Part of gage-height record furnished by United States Forest 

Service.

22, 1920, to September 30, 1921.

GAGE. Inclined gage on right!bank at end of remains of old crib, dam used 

November 22 to June 26; inclined gage on right bank 75 feet upstream 

used June 27 to September 30. The gage used February 16, 1918, to 

September 2, 1920, was at about the same location as the second gage 

used in 1921, and its datum was 1.0 foot lower than both gages used 

in 1921; gage reader, S. U. Evans.

DISCHARGE MEASUREMENTS. Made from highway bridge below gage or by 

wading.

CHANNEL AND CONTROL. Control is formed by remains of an old dam, fairly 

permanent, but not the same for both gages; channel .of gravel.

EXTREMES OF DISCHARGE. Maximum stage recorded during the period November 

22 to September 30, 5.5 feet March 4 (discharge, 4,350 second-feet); minimum discharge, 6 second-feet August 30 (gage height, 1.02 feet). 

1918-1921: Maximum and minimum discharge occurred in 1921.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. -Stage-discharge relations for the two gages not the same but 

permanent; affected by ice on control January 12-21 and by a temporary 

diversion dam August IS to Sepember 30. Rating curve for gage used 

November 22 to June 26, well -defined above and poorly defined below 200 

second-feet; curve used June 27 to September 30 well defined above and 

poorly defined below 70 second-feet. Staff gage read to hundredths once 

daily. The gage is difficult to read above & stage of 4.5 feet; observer's 

readings above that point have been reduced to conform to gage readings 

made by visiting engineers. Daily discharge ascertained by applying daily 

gage height to rating tables, except August 13 to September 30 when they 

are applied indirectly. Records fair except for discharge above 3,000 and 

below 70 second-feet, which are poor.
