SURFACE WATER SUPPLY OF SNAKE RIVER BASIN,

1917.

AUTHORIZATION AND SCOPE OP WORK.

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

measurements of flow made on streams in the United States during 

the year ending September 30, 1917.

The data presented in these reports were collected by the United 

States Geological Survey under the following authority contained 

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

Provided, That this officer [the Director] shall have the direction of the Geological 

Survey and the classification of public lands and examination of the geological structure, mineral resources, and products of the national domain.

The work was begun in 1888 in connection with special studies 

relating to irrigation in the arid west. Since 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, and 

for the investigation of underground currents and artesian wells, and for the preparation of reports upon the best methods of utilizing the water resources.

Annual appropriations for the fiscal years ending June 30,1895-1918.

1895......................................................... $12,500

1896......................................................... 20,000

1897 to 1900, inclusive......................................... 50,000

1901 to 1902, inclusive......................................... 100,000

In the execution of the work many private and State organizations 

have cooperated, either by furnishing data or by assisting in collecting 

data. Acknowledgments for cooperation of the first kind are made 

in connection with the description of each station affected; cooperation of the second kind is acknowledged on page 5.

Measurements of stream flow have been made at about 4,240 

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

the Hawaiian Islands. In July, 1917, 1,180 gaging stations were 

being maintained by the Survey and the cooperating organizations.
2 SURFACE WATER SUPPLY, 1917, PART XII- B.

Many miscellaneous discharge measurements were made at other 

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

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

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

available in the regular water-supply papers from time to timeV

DEFINITION OF TERMS.

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

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

into two groups (1) those that represent a rate of flow, as secondfeet, gallons per minute, miner's inches, and discharge in secondfeet per square mile, and (2) those that represent the actual quantity 

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

The principal terms used in this series of reports are second-feet, 

second-feet per square mile, run-off in inches, and acre-feet. They 

may be defined as follows:

"Second-feet" is an abbreviation for "cubic feet per second." A 

second-foot is the rate of discharge of water flowing in a channel 

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

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

unit from which others are computed.

"Second-feet per square mile" is the average number of cubic 

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

on the assumption that the run-off is distributed uniformly both as 

regards tune and area.

"Run-off in inches" is the depth to which an area would be covered if all the water flowing from it in a given period were uniformly distributed on the surface. It is used for comparing run-off 

with rainfall, which is usually expressed in 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 are here defined:

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

"relation of gage height to discharge."

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

of the channel or artificial structure below the gage which determines 

the stage-discharge relation at the gage. It should be noted that the 

control may not be the same at all stages. .- :

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

gage the gage height to which the surface of the water falls, 

when the discharge is reduced to zero.

EXP;LANATION CXP DATA. ;

The data presented in this report cover the year beginning October 

1, 1916, and ending September 30, 1917. At the beginning of January in most parts of the United States much of the precipitation ia 

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 wates 

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

of September, on the other hand, the only stored ^ater available for 

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

precipitation within that year.

The base data collected at gaging stations consist of records' of 

stage, measurements of discharge, and general information used ;fco 

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 an<i II.) 

The general methods are outlined in standard textbooks on the 

measurement of river discharge.

SVom the discharge measurements rating tables are prepared that 

give the discharge for any stage, and these rating tables, when applied 

to the gage heights, give the daily discharge from which the monthly 

4and yearly means of discharge are 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.

The description of the station gives, in addition to statements 

regarding location and equipment, information in f egard to any conditions that may affect the permanence of the stage-discharge relation? 

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

for log driving, shifting of channel, 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 

statges, and the accuracy of the records.

The table of daily discharge gives the discharge in second-feet 

corresponding to the mean of the gage heights read each day. At 

stations on streams subject to sudden or rapid diurnal fluctuation the 

discharge obtained from the rating table and the mean daily gage 

height may not be the true mean discharge for the day. If auch
4 SURFACE WATER SUPPLY, 1917, PART .XII B.

stations are equipped with water-stage recorders, the true mean daily 

discharge may be obtained by computing the mean daily gage 

height and applying it to the rating table, by averaging quantities 

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

discharge integrator, an instrument operating on the principle of the 

planimeter and containing as an essential element the rating curve 

of the station.

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

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

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

indicate correctly the stage when the water surface was at crest 

height and the corresponding discharge was consequently larger than 

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

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

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

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

this average flow computations recorded in the remaining columns, 

which are defined on page 2, are based.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS.

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

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

of observation of stage, measurement of flow,, and interpretation of 

records. , A paragraph in the description of the station gives information 

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

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

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

discharge.1

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 depth of 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"

i For a more detailed discussion of the accuracy of stream-flow data s4e Grover, N. C., and Hoyt, J. C., 

Accuracy of stream-flow data: U. S. Geol. Survey Water-Supply Paper 400, pp. 53-59,1916.
; DIVISIOIST OE WORK. 5

and "Run-off in inches" are therefore not computed if such errors 

appear probable. The computations are also omitted for stations 

on streams draining areas in which the annual rainfall is less than 20 

inches. All figures representing "second-feet per square mile" and 

"run-off in inches" previously published by the Survey should be 

used with caution because of possible inherent sources of error not 

known to the Survey.

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.

COOPERATION.

During the year ending September 30, 1917, work in the Snake 

River basin was carried on in cooperation with the States of Oregon, 

Nevada, and Washington, effected under contracts made between 

the Director of the Federal Survey and the State engineers or other 

officials and authorized by legislative acts appropriating money.

Special acknowledgements are due to Mr. John H. Lewis, State 

engineer of Oregon; to Mr. Henry Landes, State geologist of Washington ; and to Mr. W. M. Kearney, succeeded by Mr. J. G. Scrugham, 

State engineer of Nevada; for the efficient manner in which they 

represented their States in the investigations.

Acknowledgements are due also to the United States Reclamation 

Service, the United States Forest Service, and the United States 

Indian Office, which permitted the freest use of data gathered exclusively for them and paid for by them. The United States Weather 

Bureau and the officials of Yellowstone National Park furnished hydrometric and climatic data.

The following cities, private companies, and individuals have 

aided in the collection of records by paying the expense of work or 

otherwise assisting: City of Pocatello, Twin Falls Canal Co., Idaho 

Power Co., Twin Falls North Side Land & Water Co., Maney Bros. 

Construction Co., Mr. P. W. McCarthy, Mr. Charles Skipper, and Mr. 

T. C. Shawver.

DIVISION OF WORK.

SNAKE RIVER NEAR KORAN, WYO.

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

County, and United States Reclamation Service dam at outlet of Jackson Lake.

No important tributaries between dam and station. 

DRAINAGE AREA. 820 square miles.

RECORDS AVAILABLE. September 21, 1903, to September 30, 1917. 

GAGE. Inclined staff on left bank. Datum lowered 1.0 foot on July 26,1915. Stevens

water-stage recorder installed June 14, 1917, on bank at rear of staff gage. Gage

read by employees of United States Reclamation Service. 

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

wading. 

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

permanent. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 9.30 feet June 18-20

(discharge, 12,000 second-feet); minimum stage recorded, 0.72 foot at 3.15 a. m.

September 30 (discharge, 44 second-feet).

1903-1917: Maximum stage recorded, 8.8 feet (old datum) July 6, 1910 (discharge, 12,100 second-feet); practically no flow during a few days in 1907 and 1909

owing to closing of gates in Jackson Lake dam. 

ICE. Stage-discharge relation not affected by ice. 

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

Lake.
SNAKE BIVEB.

REGULATION. Flow controlled by operation of gates in Jackson Lake dam. Storage 

capacity of reservoir, 790,000 acre-feet.

ACCURACY. Two well-defined rating curves used^ one applicable October 1 to June 

15, the other June 18 to September 30. Shifting-control method used June 16 

to 17. Discharge October 1 to July 14 obtained by applying mean daily gage 

height to rating table; discharge July 15 to September 30 is the mean of hourly 

discharge. For high stages, rating curve defined by measurements made 

during 1917 and 1918 indicates that discharge greater than 7,000 second-feet as 

published for the years 1910 to 1916, inclusive, is probably too small. Records 

good except for period June 23 to July 14, for which they are fair.

COOPERATION. Gage-height records furnished by United States Reclamation Service.

SNAKE RIVER AT ALPINE, IDAHO.

LOCATION. In T. 3 S., R. 46 E., 300 yards below ranch house, 1 mile below highway 

bridge at Alpine, Bonneville County, and Idaho-Wyoming State line. Salt 

River enters just above station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. June 20, 1916, to September 30,1917.

GAGE. Vertical staff in two sections on right bank. Stevens water-stage recorder 

installed June 1, 1917, at site of low-water staff. Observers, Mrs. Hattie Miller 

and T. R. Newell.

DISCHARGE MEASUREMENTS. Made from highway bridge, or from cable installed 

June 14, 1917, 200 feet downstream from gage, and below mouth of Salt River. 

Measurements of the flow of Snake River at the highway bridge are combined 

with those of the flow of Salt River to obtain the flow below mouth of Salt River.

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

stages. - Control shifts during high water.

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

recorder, 10. 99 feet atl a. m. June 19 (discharge, 38,200 second-feet); minimum 

stage recorded, 2.70 feet at 9 a. m. November 15-16 (discharge, 2,130 second-feet)!

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

winter.

REGULATION. Flow controlled by storage at Jackson Lake reservoir, which was 

completed in 1916. Capacity of reservoir about 790,000 acre-feet.

ACCURACY. Stage-discharge relation changed during high water in June. Rating 

curve used before change fairly well denned between 2,500 and 27,000 secondfeet; curve used after change well defined between 4,000 and 33,000 second-feet. 

Gage read to hundredths once daily September 30 to. December 2 and May 3 to 

June 1; after that date, mean daily gage heights obtained by inspecting recorder 

graph. Operation of water-stage recorder satisfactory. Daily discharge ascertained by applying daily gage height to rating table or by shifting-control method 

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

SNAKE RIVER NEAR HEISE, IDAHO.

LOCATION. In sec. 5, T. 3 N., R. 41 E., 600 feet above Anderson dam, in Bonneville 

County, 3 miles above Heise, and 25 miles below site of station formerly maintained near Lyon. Several small creeks enter between the two stations.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 25, 1910, to September 30, 1917.

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

to vertical staff gage; inspected by Parley Byington.

DISCHARGE MEASUREMENTS. Made from cable about 100 feet below gage.

CHANNEL AND CONTROL. Bed composed of coarse gravel and cobblestones. Two 

channels at low and medium stages. Control formed by crest of Anderson dam. 

The dam was washed out during high water of June, 1917, causing considerable 

change in the stage-discharge relation.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 10.20 feet at 2.30 

and 4.30 p. m. June 18 (discharge, 38,900 second-feet); minimum stage recorded, 

from water-stage recorder, 1.79 feet at 6 p. m. April 19 (discharge, 3,200 secondfeet); actual extremes probably occurred during periods of no record.

1910-1917: Maximum stage recorded, as stated above; minimum stage, 1.1 

feet at 10 a. m. March 10, 1915 (discharge, 2,180 second-feet); actual maximum 

probably occurred during period of no record.

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

during winter.

DIVERSIONS. No large diversions above station. A small ditch of about 20 secondfeet capacity takes out just above station.

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

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

during high water in June when Anderson dam was washed out. Standard rating 

curve used before change, well defined between 2,200 and 27,000 second-feet; rating 

curve used after change, well defined between 4,000 and 20,000 second-feet. 

Operation of water-stage recorder satisfactory except on July 24, September 4-S, 

and September 8-9, when inlet to float well was clogged. Daily discharge ascertained by applying mean daily gage height to rating table except for period July 

16 to September 29, for which the mean of hourly discharges was used. Records 

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 mites southwest of Blackfoot, Bingham County. Blackfoot Eiver 

is the only large tributary between station and mouth of Henrys Fork, 60 miles 

above. Portneuf and Bannock rivers, together with 2,500 second-feet of spring 

water, enter between this station and the one at Neeley.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. June 6, 1910, to September 30, 1917.

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 new staff gage 

was installed; read by James A. Clough.

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

gage.

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 during the year from water-stage recorder, 12.67 feet at 10 p. m. June 22 (discharge, 36,200 second-feet); minimum 

stage, 3.23 feet at 5 p. m. January 17 (discharge, 1,510 second-feet).

1910-1917: Maximum stage recorded, as stated above; minimum stage, 1.89 feet 

August 11 and 15, 1910 (discharge, 238 second-feet).

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

apparently not affected.

DIVERSIONS. Practically all the natural summer flow of the river is diverted above 

station.

REGULATION, Flow regulated by storage in Jackson Lake reservoir and also by storage in Blackfoot-Marsh reservoir on Blackfoot River. Practically all the summer 

flow is water released from these reservoirs.

ACCURACY. Stage-discharge relation changed slightly in Jun , Two rating curves 

used, one applicable October 1 to June 19, the other Jun * 22 to September 30. 

Rating curve used before the change, well defined between^tOO and 20,000 secondfeet; curve used after the change, well defined between 2,000 and 86,4)00 second-feet. 

Operation of water-stage recorder satisfactory except January 13 to 25. Gage read to 

hundredth*} once daily during that period. Daily discharge ascertained by 

applying to rating table mean daily gage height obtained by inspecting gage-height 

graph; shifting-control method used June 20 and 21. Records good.

SNAKE EIVBE. 17 

SHAKE RIVES AT HEEISY. 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 Palls, and 32 miles above Minidoka dam. 

Portneuf and Bannock rivers and 2,500 second-feet of spring water enter Snake 

River between station near Blackfoot and that at Neeley. Raft River enters 

18 miles below Neeley.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 17, 1906, to September 30, 1917.

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

staff gage originally used; inspected by Morgan and Richards.

DISCHARGE MEASUREMENTS. Made from cable at gage.

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

right bank. Banks high and clean. One channel at all stages. Control is of 

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

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

11.73 feet at 2 a. m. 'June 24 (discharge, 37,700 second-feet); minimum stage, 4.9 

feet at 9 a. m. February 6; minimum discharge of about 3,700 second-feet probably occurred about January 17.

1906-1917: Maximum stage recorded, 12.5 feet June 11, 1909 (discharge, 41,100 

second-feet); minimum stage recorded, 3.65 feet August 20-22, 1906 (discharge, 

2,220 second-feet).

ICE. Stage-discharge relation seriously affected by ice during parts of December, 

January, and February; flow estimated principally by comparison with the record 

obtained at the Blackfoot station.

DIVERSIONS. Numerous canals in the vicinity of Blackfoot and Idaho Falls divert 

practically the entire natural summer flow of Snake River.

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

on the Minidoka project and Twin Falls tracts.

ACCURACY. Stage-discharge relation permanent during year except as affected by 

ice. Rating curve well defined. Operation of water-stage recorder satisfactory, 

except November 19 to March 24, during which period staff gage was read to hundredths once daily. Mean daily gage heights obtained by inspecting recorder 

graph and from staff record. Daily discharge ascertained by applying mean 

daily gage height to rating table, except as noted in footnote to daily-discharge 

table. Records good. ! ;

NOTE. Add 4.200 feet to gage heights to reduce to sea-level datum.
SNAKE KTVEB.

SNAKE RIVER HEAR MINIDOKA, IDAHO.

LOCATION. In sec. 2, T. 9 S., R. 25 E. } 100 yarda below Howell's ferry, 1 mile below . 

Reclamation Service dam, 6 miles southeast of Minidoka post office, Minidoka 

County, nea?e8t railroad point, and 6 miles above Montgomery's ferry station, 

which was discontinued December 31, 1910. Raft River enters between station 

at Neeley and that near Minidoka.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 21, 19l6, to September 30. 1917.

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 April 1,1915. Gage read by employees1 of United States Reclamation Service.

DISCHARGE MEASUREMENTS. Made from cable about 50 feet downstream from gage.

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

Control shifts slightly but infrequently.

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

13.72 feet at 10.30 p. m. June 24 (discharge, 34,900 second-feet); minimum stage, 

5.32 feet at 12.10 a. m. October 1 (discharge, 3,140 second-feet).

1910-1916: Maximum stage recorded, 14.18 feet from 4 to 5 p. m. June 8, 1914 

(discharge, 36.400 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 is formed in vicinity of gage and river closes farther downstream; stage-discharge relation affected at times.

DIVERSIONS. The North Side and South Side Minidoka canals divert water between 

the Neeley and Minidoka stations. (See pp. 97-100.) The nearest diversions 

below the station are the Twin Falls North Side and South Side canals, at Milner. 

(See pp. 100-104.)

REGULATION. Flow partly regulated by storage above Minidoka dam (storage capacity, 54,000 acre-feet).

ACCURACY. Stage-discharge relation permanent during year except as affected by 

ice. Rating curve well defined. Operation of water-stage recorder satisfactory 

except during very short periods, when Stevens long-distance recorder records 

were used. Discharge ascertained by applying to rating table mean daily gage 

height obtained by inspecting gage-height graph except as noted in footnote to 

daily-discharge table. Daily-discharge record from December 1 to February 28 

too unreliable to warrant publication, on account of insufficient data for ice 

study. Monthly discharge as published for this-period is believed to be fairly 

accurate. Records October 1 to November 30 and March 1 to September 30, 

good.

COOPERATION. Gage-height record furnished'by United States Reclamation Service.

Discharge measurements of Snake River near Minidoka, Idaho, during the year ending

SNAKE RIVER AT MILNER, IDAHO.

LOCATION. In sec. 29, T. 10 S., R. 21 E., 300 yards below Milner dam, at Milner, 

Twin Falls County. No tributaries enter Snake River between Minidoka station 

and Milner, and no large amount of water between Milner and station near Twin 

Falls except seepage and spring water.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 10, 1909, to September 30, 1917.

GAGE. Staff gage in three sections; installed October 20, 1909; high and low sections vertical, middle section inclined; read by F. W. Deming October 1 to July 

14 and September 11 to 30; by L. H. Perrine July 15 to September 10. An 

auxiliary gage in two sections is about 100 yards below main gage, to which it 

bears no definite relation; low-water section, an inclined staff on right bank; 

high-water section, an inclined staff on left bank; datum of auxiliary gage lowered 1 foot July 30 and 1 foot September 7, 1916. Gage used prior to October 20, 

1909, was a vertical staff 6n the right bank at about the same datum as the present 

gage.
26 SURFACE WATER SUPPLY, 1917, PART XII B.

DISCHARGE MEASUREMENTS. Made from a cable at gage, from foot planks at the 

auxiliary low-water gage, or by wading. Measurements may also be made from 

the suspension highway bridge a quarter of a mile below the main gage, but conditions for making measurements at this bridge are poor.

CHANNEL AND CONTROL. Bed of stream at both the main gage and the auxiliary gage 

consists of lava rock, which also forms the control for the low-water gage. Control 

for main gage is an old crib-and-rock diversion dam and is practically permanent 

for medium and high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 17.5 feet June 25 

(discharge, 28,100 second-feet); minimum stage, 1.35 feet at 8 a. m. October 1 

(discharge, 18 second-feet).

1909-1917: Maximum stage recorded, 20.1 feet June 12, 1909 (discharge, 44,400 

second-feet); minimum stage recorded, 1.08 feet (old datum on auxiliary gage) 

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

ICE. Stage-discharge relation not seriously affected by ice; open-water rating curve 

assumed applicable. Observations discontinued during part of winter because 

gages are inaccessible to observer.

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

station. During part of the season practically the entire flow of the river is taken 

by these canals.

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

dam.

ACCURACY. Stage-discharge relation changed during high-water period. Rating 

curve-fairly well defined before change; not well defined after change. Gage 

read to hundredths once daily while water is being released from storage, and to 

half-tenths once daily during rest of year. Daily discharge ascertained by applying mean daily gage height to rating table and by ahifting-control method. 

Records only fair because of infrequency of gage readings and discharge measurements and sudden changes in flow.

COOPERATION. Gage-height record furnished by the Twin Falls Canal Co., and some 

discharge measurements were made by an assistant of the State engineer.

SHAKE RIVER HEAR TWIN FALLS, IDAHO.

LOCATION. In sec. 33, T. 9 S., R. 17 E., at Perrine's bridge, on I. B. Perrine'e 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, when station was discontinued.

69971 22 WSP 463 3
28 SURFACE WATER SUPPLY, 1917, PART XII B.

GAGE. Inclined staff on left bank about 100 feet above bridge; read by T. 0. 

Shawver.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Bed of river at measuring section very rough. Banks 

high; not subject to overflow. Control consists of lava boulders and solid rock; 

permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 12*6 feet at 6.10 

p. m. June 25 (discharge, 29,300 second-feet); minimum stage recorded, 2.5 feet 

October 1 and 2 (discharge, 720 second-feet).

1911-1917: Maximum stage recorded, IS.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 

27-30, July 1-4, 9-16, 18-20, 28-29, 31, and August 1-3, 6-7, 1915 (discharge, 468 

second-feet).

ICE. Stage-discharge relation not seriously affected by ice. Open-channel rating 

curve assumed applicable.

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 is regulated directly by the diversions of the 

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

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

consists of inflow and seepage between this station and that 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 of monthly discharge excellent, though parts of the records of daily discharge may be somewhlt 

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

COOPERATION. Gage-height record furnished by T. C. Shawver.

The following discharge measurement was made by C. G. Paulsen: 

November 17, 1916: Gage height, 5.66 feet; discharge, 5,700 second-feet.

SNAKE RIVER NEAR HA0ERMAH, IDAHO.

LOCATION. In sec. 2, T. 8 S., R. 13 E., at Owsley's ferry, just above Upper Salmon 

Falls, and 4 miles south of Hagennan, Gooding County. Big Wood River enters 

10 miles below.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. August 24, 1912, to June 18, 1917, when station was discon 

tinued.

GAGE. Stevens water-stage recorder on right bank about 200 feet above the ferry; 

installed November 15, 1916, and referred to an outside staff set at same datum 

as former gage; read by C. Owsley. Previous to November 15, vertical staff on 

left bank about 50 feet below ferry, installed August 15, 1915, at same site and 

datum as former inclined gage.

DISCHARGE MEASUREMENTS. Made from cable about 100 feet below gage.

CHANNEL AND CONTROL. Control rocky; practically permanent during year.

EXTREMES OP DISCHARGE. Maximum and minimum stages during year not determined because of unreliable gage-height record.

1912-1915: Maximum etage recorded, 7.75 feet at 6 p. m. June 10, 1914 (discharge, 35,100 second-feet); minimum stage recorded, 3.1 feet July 15 to August 

2, 1915 (discharge, 4,030 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. No noteworthy diversions between this station and that at Milne*. 

Practically entire flow of river is diverted at Milner during part of the irrigation 

season by the Twin Falls canals, and the flow at Owsley's ferry is maintained 

largely by springs and waste water from irrigation;

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

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

curve well defined. Gage-height record not satisfactory, owing to poor operation 

of recorder and unreliable observer. Daily discharge ascertained by applying 

to rating table mean daily gage height obtained by inspection of recorder graph. 

For periods when recorder was not operating, discharge was estimated or interpolated on basis of observer's record. Daily discharge may be subject to large 

error, but monthly discharge is believed to be fairly accurate.

SNAKE BIVBR. SI

SNAKE RIVEK AT KING HILL, IDAHO. A

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, 1917. '.

GAGE. Inclined staff on right bank; installed August 17, 1910; read by P» W, McCarthy. Original gage, used May 13, 1909, to March 1, 1910, was a verfical staff 

on left bank at practically the same section as present gage, but at datum about 

2.2 feet higher. Temporary staff gage three-fourths mile above present site, 

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 OF DISCHARGE. Maximum stage recorded during year, 13.8 feet at 6 

p. m. May 31 (discharge, 36,600 second-feet); minimum stage recorded, 5.6 

feet October 1, 2, August 7-18, September 1-2 (discharge, 6,610 second-feet).

1909-1917: Maximum stage recorded, 13.1 feet June 12, 13, 1909 (discharge, 

41,900 second-feet); minimum stage recorded, 4.5 feet July 7-9 and August 15, 

16, 1910 (discharge, 4,760 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. No noteworthy diversions for irrigation are made between this station 

and that at Milner.

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

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

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

Falls tracts.

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

curve fairly well defined. Gage read to quarter-tenths once daily until May 1, 

after which date it was read about thrice weekly. Daily discharge ascertained 

by applying daily gage height to rating table and interpolating for days of no 

leights. Records good.

SNAKE RIVER NEAR MURPHY, IDAHO.

LOCATION . In NW. J sec. 18, T. 2 S., R. 1 E., three-quarters of a mile below Swan

Falls power plant, 1J miles below company ferry, and 12 miles east of Murphy,

Owyhee County. Gage is in Ada County 38 miles below mouth of Bruneau River.

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

RECORDS AVAILABLE. August 21, 1913, to September 30, 1917. Fragmentary records

prior to August 21, 1913.
SNAKE 1IVEB.

GAGE. Pries water-stage recorder on right bank a quarter of a mile .fcelow house 

.onranchof S. N. Glass;installed September 7,1914;inspected by S.N. Glass. Temporary vertical staff gage installed at this site August 29, 1912, was replaced 

August £2, 1913. Friez water-stage recorder, temporarily installed December 

13, 1913J, to June 27, 1914. All gages at practically same site and set to same 

datum.

DISCHARGE MEASUREMENTS. Made from ferry boat 1| miles above gage.

CHANNEL AND CONTROL. Stream bed of lava rock with deposits of sand, silt, and gravel 

where not scoured out by current. Control practically permanent. Banks not 

subject to overflow.

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

11.85 feet at 6 p. m. June 1 (discharge, 38,300 second-feet); minimum stage, 

about 2.25 feet at 6 a. m. August 6 (discharge, about 5,000 second-feet).

1912-1917: Maximum stage recorded, 12.13 feet at 11.30 a. m. June 10,1914 (discharge, 39,600 second-feet); minimum stage occurred in 1917.

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 manipulation of 

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

small amount of storage at dam the changes are of short duration.

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

curve well defined. Operation of water-stage recorder satisfactory, except as noted 

in footnote to table of daily discharge. Daily discharge ascertained by apply-? 

ing to rating table mean daily gage height obtained by inspecting recorder 

graph. Records fair.

COOPERATION. Gage-height record furnished by Idaho Power Co.

No discharge measurements were made at station during the year.

Daily discharge, in second-feet, of Snake River near Murphy, Idaho, for the year ending

SNAKE RIVER AT WEISKB, IDAHO.

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

Washington County. Between this station and that near Murphy, Sucker Creek 

and Owyhee and Malheur rivers enter Snake River from left and Boise, Payette, 

and Weiser rivers from right.

DRAINAGE ABBA. Not measured.

RECORDS AVAILABLE. October 8, 1910, to September 30, 1917. Fragmentary gageheight records obtained by Weather Bureau since 1895.

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

J. W. Lapish. 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 about 200 yards below bridge.

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

all stages. Control fairly permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 11.9 feet May 28-29 

(discharge, 70,400 second-feet); minimum stage recorded, 1.8 feet August 14 (discharge, 6,490 second-feet).

1910-1917: Maximum stage recorded, 14.5 feet (United States Geological Survey 

gage datum) June 15, 1912 (discharge, 73,800 second-feet); minimum stage, 1.5 

feet (Weather Bureau datum) at 8 a. m. August 28 and 29,1915 (discharge, 5,550 

second-feet).

ICE. Stage-discharge relation not seriously affected by ice; open-channel rating curve 

used throughout the year, except for period January 20-28.

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

but almost entirely by pumping.

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

defined. Gage read to tenths once daily. Daily discharge ascertained by 

applying daily gage height to rating table, except for period when stage-discharge 

relation was affected by ice, for which it was estimated. Records good.

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

Discharge measurements of Snake River at Weiser, Idaho, during the year ending Sept. SO,

1917.

SNAKE RIVER AT RIPARIA, WASH.

LOCATION. In sec. 31, T. 13 N., R. 38 W., at Oregon-Washington Railroad & Navi ;ation Go's bridge at Riparia, in Whitman County.

DRAINAGE AREA. 102,000 square miles (authority, United States Weather Bureau).

RECORDS AVAILABLE. October 1, 1915, to September 30, 1917. Gage-height record 

during parts of May and June, 1900-2, May 1 to November 30, 1904, July 1, 

1905, to December 31, 1906, February 1, 1908, to June 30, 1910, and August 1, 

1910, to February 28, 1917, obtained and published by United States Weather 

Bureau.

GAGE. Vertical staff in three sections, the highest section being on first bridge pier 

from right bank, and the lower sections on upper draw guard of bridge. On September 12, 1917, chain gage installed on bridge at same datum; read by R. E. 

Wilcox.

DISCHARGE MEASUREMENTS. Made from bridge at gage.

CHANNEL AND CONTROL. Texas Rapids, about half a mile below gage, forms control. 

The United States Army Engineer Corps is removing rock from the channel and 

dumping it on another part of the control, but this work apparently does not 

affect permanence of stage-discharge relation.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 18.2 feet May 30 

(discharge, 256,000 second-feet); minimum stage recorded, 1.4 feet September. 

3-10 and 23 (discharge, 16,200 second-feet).

1916-17: Maximum stage recorded same as for 1917; minimum stage recorded, 

1.4 feet October 1, 1915, and September 3-10 and 23, 1917 (discharge, 16,200 

second-feet, revised since publication in Water-Supply Paper 443).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. A large amount of water is diverted for irrigation.

REGULATION. Flow is regulated to some extent by storage for irrigation in Jackson 

Lake reservoir (capacity, 790,000 acre-feet) and other smaller reservoirs in the 

basin; also by diversions for irrigation.

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

read to tenths once daily. Daily discharge ascertained by applying daily 

gage height to rating table. Records prior to March good, for first half of March 

fair, and for remainder of year excellent.

COOPERATION. Gage-height record furnished by United States Army Engineer 

Corps and United States Weather Bureau.

RECORDS AVAILABLE. July 31 to November 11, 1906; July 20 to September 30, 1917,

when station was temporarily discontinued. 

GAGE. Vertical staff on right bank; read by R. B. Lozier. Lietz water-stage recorder

installed July 19, 1917, but owing to unsatisfactory operation discharge is based

chiefly upon daily gage-height readings. 

DISCHARGE MEASUREMENTS. Made by wading or from two highway bridges 500

feet above gage.

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

EXTREMES OF DISCHARGE. Maximum stage recorded during 1917, 2.31 feet July 20

(discharge, 68 second-feet).

DIVERSIONS. None within 3 miles above or below gage. 

REGULATION. None. 

ACCURACY. Stage-discharge relation not permanent. Two fairly well denned

rating curves used, one applicable July 20 to August 8, the other August 22 to

September 30. Operation of water-stage recorder unsatisfactory. Daily dis~ 

.charge ascertained by applying daily gage height to rating table; interpolated 

>; for days of no gage height, except September 20-24, for which it was estimated; 

^gjpf ting-control method used August 9-21. Records after August 8, good.

CHANNEL AND CONTROL. Bed composed of loose gravel; shifting. Banks low and 

subject to overflow at medium stages. Two channels at low stages; numerous 

channels at high stages; channel curved above and below gage.

EXTREMES OF DISCHARGE. Maximum stage recorded, 1.68 feet July 7 (discharge, 

indeterminate because of shifting control and poor definition of rating curve at 

that stage); minimum stage recorded, 0.86 foot at 7 a. m, September 22 (discharge, 

60 second-feet).

curves used; one applicable July 15 to 29, the other August 8 to 20 and August 

27 to September 12. For remaining periods of year shifting-control method was 

used, based upon measurements which define shifts very well for intervening 

periods. Gage read to quarter-tenths twice daily prior to July 16, and to hundredths twice daily for remainder of season. Daily discharge ascertained by 

applying mean daily gage height to rating table or by shifting-control method, 

except the period July 4-14 for which rating curve was not defined. Records 

fair.

RECORDS AVAILABLE. April 5, 1916, to August 5, 1917. 

GAGE. Vertical staff on right bank; read by W. C. Handy and A. C. Morris. 

DISCHARGE MEASUREMENTS. Made from cable near gage or by wading.
TRIBTJTABY BASINS. 77

CCE. At times flow from lake is practically shut off by ice but springe probably keep 

channel free from ice near gage.

EXTREMES or DISCHARGE. Maximum stage recorded during season, 5.9 feet at 9 a. m. 

May 15 (discharge, 1,350 second-feet); minimum stage not definitely known but 

during early part of April discharge was about 1.0 second-foot.

1916-1917: Both maximum and minimum stages occurred in 1917.

DIVERSIONS. No diversions between lake and station. Diversions for irrigation 

are made above the lake, but amount of water diverted is not known.

REGULATION. No artificial regulation above station.

Accuracy. Stage-discharge relation practically permanent. Gage read to tenths 

once daily May 1-28 and to quarter-tenths thereafter. Two well-defined rating 

curves used, one applicable October 1 to November 4, the other May 1 to August 5. 

Daily discharge ascertained by applying daily gage height to rating table, except 

for days of no gage reading for which it was interpolated. Records good.

IDAHO (GOVERNMENT) CANAL NEAR SHELLEY, IDAHO.

LOCATION. In sec. 31, T. 1 N., R. 37 E., Bingham County, 600 feet below canal 

headgates, 1J miles southwest of Shelley, and 10 miles above point where Sand 

Creek crosses canal.

RECORDS AVAILABLE. June 20, 1912, to September 30, 1917. No water diverted 

during 1913 because of break in the canal.

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

by J. A. Vaughn. Bristol water-stage recorder has been operated at times, but records were not satisfactory; inclined staff always used as standard reference gage.

DISCHARGE MEASUREMENTS. Made by wading or from a suspension footbridge at 

the gage.

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

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

section evidently furnishes a permanent point of zero flow at about 0.0 foot gage 

height.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.45 feet at 10 

a. m. July 6 (discharge, 218 second-feet); minimum flow probably zero when 

headgates are closed, but has not been definitely determined, as no records are 

obtained when gates are closed.

1912-1917: Maximum stage recorded, 3.7 feet July 29, 1912 (discharge, 308 

second-feet); minimum as stated above.

DIVERSIONS. None.

REGULATION. Flow controlled at the headgates 600 feet above.

ICE. Canal not operated during winter.

ACCURACY. Stage-discharge relation sometimes affected by growth of vegetation. 

Rating curve well defined for open water; changes not defined by discharge measurements. Gage read to hundredths once daily. Daily discharge determined by 

applying daily gage height to rating table except as noted in footnote to dailydischarge table. Records fair.

Idaho 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. 27, T. 2 S., R. 36 E. The canal also 

receives water from Sand Creek about 10 miles below station.

BLACKFOOT RIVER ABOVE RESERVOIR, NEAR HENRY, IDAHO.

LOCATION. About sec. 9, T. 7 S., R. 42 E., at Cully's ranch, 1$ miles above flow 

line of Blackfoot-Mansh reservoir, 7 miles south of Henry, Bannock County, and 

13 miles north of Soda Springs.

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

RECORDS AVAILABLE. March 25. 1914, to September 30, 1917.

GAGE. Vertical staff on right bank about half a mile above Cully's house and 200 

feet below the shearing plant; read by Mrs. T. W. Cully until May 1, and Mrs. 

A. C. Swanson for remainder of year. The original gage used March 25 to September 30, 1914, was a vertical staff attached to streamward side of right bridge pier 

about three-fourths of a mile above.

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

CHANNEL AND CONTROL. One channel at all stages, although the right bank near 

gage is probably subject to overflow at high stages. Bed of stream is rough; 

composed of loose rocks and boulders and some gravel. Control is of loose rock; 

fairly permanent.

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

mark above gage, about 6.8 feet, May 16 (discharge, 2,060 second-feet); maximum 

stage recorded during year, 6.1 feet at 1 p. m. May 17 (discharge, 1,680 secondfeet); minimum stage recorded, 1.65 feet at 10.30 a. m. November 13 (measured 

discharge, 52 second-feet); minimum discharge may have occurred during winter 

when stage-discharge relation was affected by ice.

1914-1917: Maximum stage recorded May 16, 1917 (see above); minimum stage 

recorded, 1.40 feet at 9.30 a. m. September 1, 1915 (discharge, 55 second-feet). 

Minimum discharge probably occurred during winter.
80 SUBFACE WATER SUPPLY, 1917, PART XII B.

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

during winter.

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

REGULATION. None. The entire flow passing gage is impounded in the BlackfootMarsh reservoir 1J miles below.

ACCURACY. Stage-discharge relation permanent, except as affected by ice. Two 

fairly well-defined rating curves used, one applicable October 1 to November 5, the other April 23 to September 30, except as noted in footnote to dailydischarge table. Gage read to hundredths once daily. Daily discharge ascertained 

by applying daily gage height to rating table, except as indicated in footnote to 

daily-discharge table. Records good, except for November, for which they are 

poor.

82 SURFACE WATER SUPPLY, -1917, PART XII B. 

BLACKFOOT RIVER KBAR HENRY, IDAHO.

LOCATION. In sec. 11, T. 5 S., R. 40 E., 200 feet below wagon bridge at Rockyford 

crossing, 1 mile below Blackfoot-Marsh dam of United States Indian Service and 

12 miles northwest of Henry, Bannock County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. July 15, 1908, to September 30, 1917.

GAGE. Friez water-stage recorder installed September 18, 1912, in wooden shelter 

on left bank; referred to outside vertical staff. Prior to September 18,1912, gage 

was a vertical staff a few feet downstream from present gage. The datum of original gage lowered 0.11 foot between July 15, 1908, and May 25, 1912; and the 

datum of the present gage is the same as original gage on May 25, 1912. B. B. 

Reynolds makes daily staff gage readings and inspects the Friez recorder.

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

wading.

CHANNEL AND CONTROL. One channel at all stages. Stream bed consist of lava 

rock, boulders, and gravel. Control is fairly permanent. Growth of moss at 

times affects stage-discharge relation.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 3.04 feet June

21 and morning of June 22 (discharge, 822 second-feet), minimum stage, 0.50

foot afternoon of May 11 and morning of May 12 (discharge, about 1 second-foot).

1908-1917: Maximum stage recorded, 4.15 feet May 14, 1909 (discharge, l,64o

second-feet); minimum stage recorded May 11, 12, 1917.

ICE. Stage-discharge relation slightly affected by ice.

DIVERSIONS. Only a few small diversions are made for purposes of irrigation from 

the river and its tributaries above the reservoir.

REGULATION. Flow past station consists entirely of stored water from reservoir and 

is controlled by gates at the dam.

ACCURACY. Stage-discharge relation affected by growth of aquatic plants. Two 

well-defined rating curves used. Recorder not operating November 6 to June 22; 

stage determined from daily readings on staff gage; mean daily gage heights for 

rest of year obtained by inspecting recorder graph. Daily discharge ascertained 

by applying daily gage height to rating table, except as indicated in footnote to 

daily-discharge table. Open-water records good; winter records fair.

material; fairly permanent. One channel at all stages. Banks covered with 

heavy growth of brush and willows, which may affect stage-discharge relation at 

high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 9.03 feet at 2.30 

p. m. May 31 (discharge, 671 second-fee^); minimum stage, 4.5 feet at 8.10 p. m. 

June 29 (discharge, estimated 65 second-feet).

1913-1917: Maximum stage recorded, 9.03 feet May 31, 1917; maximum discharge recorded, 673 second-feet September 21-22, 1914; water below gage at 

7.20 p. m. June 17, 1915 (discharge, estimated 40 second-feet).

ICE. No records obtained during winter.

DIVERSIONS. Principal diversions above gage are the Fort Hall canals near Blackfoot, but several smaller diversions are made near Blaekfoot.

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

United States Indian Service, and by manipulation of headgates of Fort Hall 

canals near Blaekfoot.

ACCURACY. Stage-discharge relation permanent during period of record. Rating 

curve well defined above 120 second-feet. Gage read to hundredths once daily. 

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

MEADOW CREEK NEAR HENRY, IDAHO.

LOCATION. In sec. 3, T. 6 S., R. 42 E., half a mile above flow line of Blackfoot-Marsh 

reservoir, three-quarters of a mile below Goose Lake or Pelican Slough, and 1J 

miles northeast of Henry, Bannock County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 17, 1914, to September 30, 1917.

GAGE. Stevens continuous water-stage recorder installed June 27,1914, on left bank; 

inspected by Ray Christensen. Vertical staff at same location and datum used 

April 17 to June 26,1914.

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

CHANNEL AND CONTROL. Control consisted originally of an old rock diversion dam 

about 100 feet below gage, but this was torn out August 17-19, 1915, and stagedischarge relation completely changed. New control is of rocks and gravel; 

somewhat shifting. One channel at all stages, but banks are covered with brush 

and stage-discharge relation may be affected.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 4.81 feet at 12.10 

a. m. May 17 (discharge, 424 second-feet); minimum stage recorded, 1.83 feet at 

2 p. m. September 22 (discharge, 11 second-feet).

1914-1917: Maximum stage recorded May 17, 1917; minimum stage recorded, 

about 1.06 feet July 17, 1916 (discharge, about 0.4 second-foot).

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

during winter.

DIVERSIONS. None above gage.

REGULATION. None.

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

curves used, one applicable October 1 to November 11 and May 1 to June 13, the 

other June 14 to September 30. Daily discharge ascertained by applying to 

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

except for winter and the periods indicated in footnote to daily-discharge table. 

Records fair.

IDAHO (GOVERNMENT) CANAL HEAR FIRTH, IDAHO.

LOCATION. In sec. 13, T. 2 S. T R. 36 E., Bingham County, 100 feet above double 

metal flume by which canal crosses Eastern Idaho Slough, a quarter of a mile 

below nearest highway bridge, 1£ miles below point where Sand Creek crosses 

canal, and 5 miles southeast of Firth.

RECORDS AVAILABLE. March 29, 1914, to September 30, 1917.

GAGE. Friez water-stage recorder on left bank; read by Vaughn, Jensen, and Kaiser.

DISCHARGE MEASUREMENTS. Made by wading or from one of the highway bridges 

above.

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

shifts slightly but flume heading just below furnishes what should be a permanent 

control for high stages. Point of zero flow at about 0.5 or 0.6 foot gage height.

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

4.53 feet at 9 a. m. August 19 (discharge, 315 second-feet); minimum stage, 0.53 

foot at 9 a. m. April 20 (discharge, estimated as no flow); observer reported no flow 

March 14 to 28.

1914-1917: Maximum stage recorded, 5.30 feet at 3.35 p. m. June 21, 1916 (discharge, 428 second-feet); minimum stage as above stated.

ICE. Stage-discharge relation seriously affected by ice. Data inadequate for determination of winter discharge.

DIVERSIONS. None.

REGULATION. Flow partly regulated by Snake River headgates, about 12 miles 

above, and partly by gates at the Sand Creek crossing, about 1J miles above.

ACCURACY. Stage-discharge relation changed slightly September 18 to 21, and was 

affected by ice during winter. Rating curve well defined for open water. Operation of water-stage recorder unsatisfactory at times; supplemented by daily staff 

readings during part of year. Daily discharge ascertained by applying to rating 

table mean daily gage height obtained by inspecting recorder graph, except as 

noted in footnote to table of daily discharge. Records good for periods for which 

daily discharge is given.

Idaho (Government) canal diverts water from left bank of Snake River in sec. 31. 

T. 1N., R. 37 E., and discharges into Blackfoot River in sec. 24, T. 2 S., R. s'e E. 

The canal receives water from Sand Creek just above this station.

SAND CREEK NEAR FIRTH, IDAHO.

LOCATION. In sec. 7, T.2 S., E. 37 E., Bingham County, 400 feet downstream from 

point where Idaho (Government) canal crosses creek and 4 miles east of Firth.

RECORDS AVAILABLE. December 21, 1916, to September 30, 1917.

QA<JB. Vertical staff on left bank on upstream side of highway bridge. Prior to 

May 17,1917, vertical staff on left bank, 300 feet upstream; read by J. A. Vaughn,

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

flume crossing creek 50 feet downstream.

69971 22 WSP 463 7
92 SURFACE WATER SUPPLY, 1911, PAST XH B.

CHANNEL AND CONTEOL. Bed composed of silt, sand, and fine gravel; probably not 

permanent. Banks clean; subject to overflow at high stages. Point of zero flow, 

about 0.8 foot gage height.

EXTREMES OP DISCHARGE. Maximum discharge, estimated 211 second-feet, May 24 

and 29; minimum discharge, no flow, April 27, June 19 to July 3, July 28-29, 

and Aug. 2-4.

ICE. Stage-discharge relation seriously affected by ice. Data inadequate for determination of daily discharge during ice period.

DIVERSIONS. None below Idaho (Government) canal crossing and above the station.

REGULATION. The Idaho (Government) canal has been constructed directly across 

the channel of the creek above the station. The canal receives the entire flow 

of the creek as tributary and regulates the flow returned to creek channel below 

by means of headgates. Above this point, numerous canal systems utilize the 

creek channel as a waste ditch.

ACCURACY. Stage-discharge relation at both gages permanent for period except as 

affected by ice. Rating curves fairly well defined. Gage read to hundredths 

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

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

FORT HALL UPPER CANAL NEAR BLACKFOOT, IDAHO.

LOCATION. In sec. 13, T. 3 S., R. 35 E., Bingham County, 500 feet below headgatea 

and 3J miles southeast of Blackfoot.

RECORDS AVAILABLE. May 8, 1912, to September 30, 1917.

GAGE. Vertical staff in stilling well on right bank and sloping gage painted on right 

side about midway of concrete rating section. Bristol water-stage recorder used 

during 1912 and parts of 1913 and 1914. All gages set to same datum and at practically same site. Gage read by ditch rider and gate tender.

DISCHARGE MEASUREMENTS. Made by wading or from suspension footbridge at gage.

CHANNEL AND CONTROL. Concrete trapezoidal rating section.

EXTREMES OF DISCHARGE. 1912-1917: Maximum stage recorded, 4.90 feet at 7 p. m. 

July 28,1917; maximum discharge recorded at 6 p. m. July 20,1917, 407 secondfeet; minimum flow occurs during winter when a very small quantity of water is 

run for stock.

ICE. Observations discontinued during winter.

DIVERSIONS. None above station or for several miles below.

REGULATION. Flow regulated at headgates 500 feet above.

ACCURACY. Stage-discharge relation changed during winter; affected by moss during July, August, and September. Rating curves well defined for open water 

both before and after change. Gage read to half-tenths twice daily. Daily discharge ascertained by applying mean daily gage height to rating table, and by 

shifting-control method. Records fair.

FORT HALL LOWER CANAL NEAR BLACKFOOT, IDAHO.

LOCATION. In sec. 15, T. 3 S., R. 35 E., Bingham County, 200 feet below ford where 

road to headgates half a mile above crosses canal and 2£ miles southeast of 

Blackfoot.

RECORDS AVAILABLE. May 15, 1912, to September 30, 1917.

GAGE. Inclined staff on right bank near center of concrete rating section; read by 

ditch rider for the United States Indian Service. Bristol water-stage recorder 

at same site, but referred to datum 1.53 feet lower than that of staff gage was 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 a third of a mile below gage. Variations in amount of 

water carried in a large lateral that diverts between the gage and the check and 

the growth of moss and weeds in the canal caused several changes in stage-discharge relation during season.

EXTREMES OF DISCHARGE. 1912-1917: Maximum stage recorded during period, 3.15 

feet at 7.40 a. m. July 21, 1917 (discharge, 224 second-feet); 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 during most of winter the headgates are closed.
TBIBTTTABY BASTNS.

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

gage and the check that acts as the main control.

REGULATION. Flow regulated at the headgates half a mile above gage.

ACCURACY. Stage-discharge.relation not permanent; affected by variation in quantity of water diverted immediately below ga'ge, by changes at the control, and 

by growth of aquatic vegetation. Two'fairly well defined rating curves and one 

parallel curve used. Gage read to half-tenths twice daily. Daily discharge ascertained by applying mean daily gage height to rating table and by shifting-control 

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

96 STJEFACE WATEE SUPPLY, 1911, PAET XII B.

POB.TNETTT RIVER AT POCATELXO, IDAHO.

LOCATION. In sec. 27, T. 6 S., R. 34 E., 20 feet above old slaughter house bridge at 

foot of Carson Street, in west end of Pocatello, Bannock County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. August 31, 1911, to September 30, 1917. For station about 

a mile upstream, May 18,1897, to October 14,1899.

GAGE. Vertical staff on left bank just below highway bridge; constructed in 1914; 

read by W. S. Hutson. The gage in use 1897-99 was a vertical staff spiked to pier 

of wagon bridge one-eighth of a mile below plant of Pocatello Electric Light Co.

DISCHARGE MEASUREMENTS. Made by wading or from upstream side of old slaughter 

house bridge.

CHANNEL AND CONTROL. Bed of stream at gage and measuring section consists of 

rocks and medium-sized boulders; very rough. One channel except at extremely 

high stages when left bank is overflowed. Control fairly permanent, although 

it shifts within well-defined limits.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.2 feet at 1 p. m. 

April 13 (discharge, 1,150 second-feet); estimated discharge of more than 2,000 

second-feet during period May 13 to June 14, when left bank was overflowed; 

minimum stage recorded, 2.6 feet at 8 a. m. July 29 (discharge, 129 second-feet). 

1911-1917: Maximum stage recorded, 6.4 feet May 23 and 24, 1912 (discharge, 

1,240 second-feet); estimated maximum discharge of more than 2,000 secondfeet occurred during period May 13 to June 14, 1917, when left bank was overflowed; minimum stage recorded, 2.0 feet July 4,1915 (discharge, 52 second-feet). 

1897-1899: Maximum stage recorded, 12.80 feet May 18, 1897 (discharge, 1,880 

second-feet); minimum stage recorded, 6.10 feet July 4-11, 13, and 17-18, 1898 

(discharge, 14 second-feet).

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Numerous ranch diversions are made above the gage. The largest 

single diversion is that made by the canal of the Portneuf-Marsh Valley Canal Co., 

which diverts water for use in irrigating lands in the vicinity of Downey.

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

storage reservoir of this company is near Chesterfield and has a capacity of about 

28,000 acre-feet.

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

Rating curves, fairly well defined, used October 1 to December 31 and March 2 

to September 30. Gage read to half-tenths thrice weekly. Daily discharge ascertained by applying daily gage height to rating table and interpolating for days of 

no gage height, except during January and February when stage-discharge relation was affected by ice, and during period May 13 to 14 when stage over-topped 

the gage. Records fair.

NORTH SIDE TWIN FALLS CANAL AT MILKER, IDAHO.

LOCATION. IB sec. 20, T. 10 S., R. 21 E., Minidoka County, at highway bridge half 

a mile north of Milner post office and three-fourths of a mile below headgates at 

Milner dam.

EECOEDS AVAILABLE. May 10, 1909, to September 30, 1917.

GAGE. Vertical staff attached to downstream side of bridge near left bank; read by 

F. W. Deming, November 12,13, 21, 23, December 9 to May 6; rest of year Stevens 

8-day water-stage recorder at slightly different site and datum. Datum of gage 

practically unchanged since establishment of station. A slide gage installed on 

bridge in 1911 and set to read same as staff gage was discontinued in 1913. A 

Lietz water-stage recorder, which was installed in 1912 in a shelter over the staff 

gage, never operated entirely satisfactorily and was abandoned in 1913.
TBIBUTABY BASOTS. 101

DISCHARGE MEASUREMENTS. Made from cable 150 feet below bridge gage.

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

growth is heavy during summer and stage-discharge relation is seriously affected. Control apparently indeterminate.

EXTREMES OF DISCHAEOE. Maximum stage during year from water-stage recorder, 

8.31 feet at 6.15 p. m. July 26 (discharge, 2,930 second-feet); canal dry February 

7 to 9 and April 10 to May 2.

1909-1917: Maximum discharge as noted above; canal reported dry during 

various periods.

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

DIVEBSIONS. None between gage and headgates 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.

ACCUBACT. Stage-discharge relation not permanent, changes being due largely to 

growth of aquatic plants. Several well-defined parallel rating curves used. Staff 

gage read to half-tenths once daily, December 9 to May 6; operation of waterstage recorder satisfactory for rest of year, except November 12, 13, 21, and 

23, when staff readings were substituted. Dally discharge ascertained by applying to rating table mean daily gage height obtained by inspecting recorder graph 

or by shifting-control method. Records for periods in which gage-height record 

was tak6n from water-stage recorder excellent; those for other periods fair.

COOPERATION. Some discharge measurements furnished by State engineer of Idaho; 

gage-height record and some measurements furnished by Twin Falls North Side 

Land & Water Co.

The North Side Twin Palls canal diverts water from the north side of Snake River at 

the Milner dam and furnishes water for stock and irrigation for about 240,000 acres in 

Minidoka, Lincoln, and Gooding counties. The distribution system comprises about 

100 miles of main canal and 625 miles of laterals.

SOtTTH 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

headgates at Milner, in Twin Falls County. 

RECORDS AVAILABLE. May 10, 1909, to September 30, 1917.
TB(IBUTABY BASINS. 103

GAGE. Vertical staff in two sections; read by L. H. Perrine and F. W. Benoang, 

The main or upper section of'the gage is on the left bank of the canal about 100 

feet upstream from the highway bridge, to the lower side of which the low-water 

section is fastened. This lo\y-water section is the original gage, but on account 

of the difficulty in making readings accurately at high stages the high-water 

section was installed early in the summer of 1912 and has since been used exclusively for stages above 5.3 feet. The two sections read practically the same, although the datum of the upstream section is about 0.1 foot higher than the other. 

' A Friez water-stage recorder is installed opposite the upper staff gage; used 

June 9-16, June 23 to July 14j, July 16 to August 4, August 18-25, August 27 to 

September 15, 1917.

DISCHARGE MEASUREMENTS. Made from highway bridge and suspension bridge 150 

feet upstream.

CHANNEL AND CONTROL. Channel at gage is blasted out of rock; practically permanent. Occasionally slight changes in control are due to washing in and deposition 

of silt.

EXTREMES OF DISCHARGE. Maximum discharge during year, 3,690 second-feet October 16 and at 10 a. m. July 24; minimum stage, 1.20 feet May 17, 18, and 19 

(discharge, 23 second-feet).

1909-1917: Maximum stage as stated above; minimum stage recorded, 0.8 foot 

April 7, 1913 (discharge, 11 second-feet).

ICE. Stage-discharge relation affected by ice in canal below waste gates. Information insufficient to warrant computation for winter.

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

REGULATION. Flow regulated by headgates.

ACCURACY. Stage-discharge relation changed by ice during winter and by closing 

waste gates below station in March. Rating curve well denned for normal position of waste gates; fairly well defined for open waste gates. Gage read to tenths 

once daily except during shor^; period when operation of water-stage recorder was 

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

table except for periods noted in footnote to daily-discharge table. Records 

for October and November, fair; April to September, good.

COOPERATION. Gage-height record and part of discharge measurements furnished 

by the Twin Falls Canal Co. and by the State engineer of Idaho.

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

at the Milner dam. This canal furnishes water for stock and for irrigation of about 

200,000 acres near Twin Falls. The distribution system comprises about 110 miles 

of main canal and 590 miles of laterals.

and gravel; fairly permanent. One channel at all stages. Banks covered with 

brush; both subject to overflow. At low stages control is riffle between gage and 

Jones Brook; at high stages rapids below brook may become control.

EXTREMES OF DISCHARGE. Maximum discharge during year, 1,750 second-feet on 

May 15, estimated from hydrographic comparison with Owyhee River near 

Gold Creek; minimum stage from wateratage recorder, 1.61 feet at midnight 

August 25 (discharge, 9 second-feet).

1913-1917; Maximum stage occurred in 1917; minimum discharge, 7.5 secondfeet, August 23,1915.

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

DIVERSIONS. No important diversions above gage.

REGULATION . None.

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

1,500 second-feet. Operation of water-stage recorder satisfactory, except for 

breaks in record, as shown in footnote to daily-discharge table. Daily discharge 

ascertained by use of discharge integrator, except for breaks in gage-height record, 

for which discharge was interpolated or estimated from hydrographic comparison 

with Owyhee River near Gold Creek. Records obtained by use of integrator 

below 1,500 second-feet, good; others fair.

JORDAN CREEK NEAR JORDAN VALLEY, OREG.

LOCATION. In sec. 9, T. 30 S., R. 45 E., in canyon at lower end of Jordan Valley, 9 

miles below Jordan Valley post office, Malheur County. Cow Creek enters Jordan Creek 7 miles below station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 28,1911, to September 30,1917.
TMBUTABY BASINS. 121

GAGE. Inclined staff on right bank one-eighth of a mile below upper end of the 

canyon; read by Marcos Renteria.

DISCHABGE MEASUEEMENTS. Made by wading or from cable near gage.

CHANNEL AND CONTROL. One channel. Control consists of lava rock; probably permanent. During the summer growth of moss frequently affects the stage-discharge relation to a marked degree.

EXTEEMBS OP DISCHARGE. Maximum stage recorded during year, 12.3 feet April 26 

(discharge, 3,620 second-feet); minimum discharge, practically no flow September 10-25.

1911-1917: Maximum stage recorded, April 26, 1917; creek reported dry for 

periods of several weeks in 1911, 1914, 1915, 1916, and 1917.

ICE.T Stage-discharge relation seriously affected by ice.

DIVERSIONS. Practically the entire sxunmer flow of the stream is used by the many 

small diversions in valley above gage. Flood water is also diverted into Antelope 

reservoir.

REGULATION. None, except that due to diversions.

ACCURACY. Stage-discharge relation permanent except as affected by ice. Rating 

curve well defined. Gage read to hundredths thrice weekly except during winter 

when it was read once weekly. Daily discharge ascertained by applying daily 

gage height to rating table and interpolating for days of no gage heights, except 

for periods when stage-discharge relation was affected by ice, for which it was 

ascertained by means of observer's notes and weather records. Open-water 

records good; winter records poor.

The following discharge measurement was made by T. R. Newell: 

June 10, 1917: Gage height, 7.02 feet; discharge, 826 second-feet.

LITTLE CAMAS CREEK BELOW RESERVOIR, NEAR BENNETT, IDAHO.

LOCATION. In sec. 4, T. 1 S., R. 9 E., a short distance below Camas reservoir and I 

mile north of Bennett, Elmore County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 22 to June 30, 1917, when station was discontinued.

GAGE. MeConnel recording gage on right bank; read by C. E. Tappan, an employee 

of Idaho State engineer.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Bed of sand and fine gravel; probably shifting.

EXTREMES OF DISCHARGE. Maximum discharge during period, 80 second-feet June 

1 and 2; minimum discharge during period, estimated 0.7 second-foot June 30.

DIVERSIONS. None between station and Camas reservoir.

REGULATION. Flow regulated by headgates on Camas reservoir and indicates amount 

wasting into South Fork of Boise River.

ACCURACY. Stage-discharge relation practically permanent. Operation of waterstage recorder unsatisfactory. Rating curve well defined. Daily discharge 

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

inspection of recorder graph, and interpolation and estimates based on amount 

diverted through canal above. Records only fair, chiefly on account of poor gage- 

 height record.

COOPERATION. Station operated and maintained by Idaho State engineer.

denned and shifting.

EXTREMES OP DISCHARGE. Maximum discharge during period, 68 second-feet July 9, 

10, and 12; minimum stage recorded, 0.30 foot November 1 (discharge, no flow): 

no flow estimated on August 7.

DIVERSIONS. None.

REGULATION. The flow past station is regulated by headgates at Camas reservoir.

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

aquatic vegetation. Operation of water-stage recorder satisfactory. Daily .discharge ascertained by applying daily gage height to rating table, by estimating, 

and by shifting-control method during period when stage-discharge relation was 

affected by vegetation. Records fair.

COOPERATION. Station operated and maintained by the Idaho State engineer.

Little Camas canal diverts water from Little Camas Creek, in Boise River basin, to 

Canyon Creek basin through Long Tom Creek. The canal draws water from Little 

Camas reservoir in sec. 9, T. 1 S., R. 9 E., and discharges into Long Tom Creek in 

sec. 27, T. 1 S., R. 8 E. The capacity of the canal is about 65 second-feet.

SMITH CREEK NEAR LENOX, IDAHO.

LOCATION. In sec. 12, T. 2 N., R. 6 E., at lower crossing, half a mile above mouth 

and 5 miles northwest of Lenox, Eimore County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. January 1, 1916, to September 30, 1917. A few measurements were made by the United States Reclamation Service prior to 1916.

GAGE. Vertical staff on right bank 40 feet above bridge; read by R. S. Sandlin.

DISCHARGE MEASUREMENTS. Made from bridge or by wading at sections above gage.

CHANNEL AND CONTROL. Bed composed of lava bedrock and large lava boulders 

with some sand and gravel. Control practically permanent. One channel 

except at very high stages, when creek may overflow around right end of bridge. 

Stream turbulent in spring.

EXTREMES OF DISCHARGE. Maximum stage recorded during period, 4.2 feet May 15 

(discharge, 401 second-feet); minimum discharge, 0.2 second-foot July 27.

1916-1917: Maximum stage recorded, May 15, 1917; minimum discharge, 0.2 

second-foot August 23-30, 1916, and July 27, 1917.

ICE, Stage-discharge relation affected by ice during winter.

DIVERSIONS. Practically entire summer flow of creek diverted above station for 

irrigation on Smith Prairie and by -Krall's ditch, which heads one-eighth of a 

mile above gage. No diversions below gage.

REGULATION. Artificial regulation to a very slight extent by several small storage 

reservoirs on headwaters of stream.

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

well defined below 250 second-feet. Gage read to quarter-tenths or hundredths 

(the degree depending on the stage), two or three times weekly. Daily discharge 

ascertained by applying daily gage height to rating table and interpolating for 

days when gage was not read. On account of infrequent gage readings, record is 

considered only fair.

136 SURFACE WATER SUPPLY, 1917, PART XII B. 

RATTLESNAKE CREEK NEAR LENOX, IDAHO.

LOCATION. In sees. 27 and 28, T. 3 N., R. 6 E., half a mile above mouth of creek, 

13 miles (by water) southeast of Arrowrock, and 13 miles (by wagon road) northwest of Lenox, Elmore County.

DRAINAGE AREA. 46 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 1, 1915, to September 30, 1917. Several discharge 

measurements were made by engineers of the United States Reclamation Service 

during summer and fall of 1915.

GAGE. Prior to June 29, 1916, a vertical staff attached to downstream corner of right 

abutment of bridge one-fourth of a mile above mouth; since that date a vertical 

staff on left bank, about 300 feet farther upstream, and above the influence of 

backwater; read by S. F. Kesl and G. Aulbach.

DISCHARGE MEASUREMENTS. Made by wading at all but extremely high stages, when 

measurements may be made from highway bridge, though conditions are unfavorable.

CHANNEL AND CONTROL. Control for both gages composed of small boulders, coarse 

gravel, and sand. Since the recession of backwater from old gage, the control has 

been so changed by deposits of sand as to render records from this gage valueless. 

Control for upper gage probably fairly permanent. Channel of stream winding; 

Banks fairly high and covered with brush. Stream turbulent.

EXTREMES OF DISCHARGE. Maximum stage recorded, 2.40 feet April 12 (discharge, 

167 second-feet); minimum stage recorded, 1.15 feet September 21 (discharge, 6 

second-feet).

1915-1917: Maximum stage recorded, 2.9 feet March 21, 1916 (discharge, 182 

second-feet); minimum stage recorded September 21,1917.

ICE. Stage-discharge relation affected by ice November 11-27 and February 22 to 

March 8.

DIVERSIONS. KesPs ditch diverts from right side of creek about 3 miles above gage, 

but the average amount of water diverted probably did not exceed 1 second-foot. 

A few small diversions are made from tributaries farther upstream.

REGULATION. None other than slight effect of diversions.

ACCURACT. Stage-discharge relation practically permanent for both gages. Rating 

curve fairly well defined. Gage read to hundredths at rather irregular intervals 

averaging about thrice weekly. Daily discharge ascertained by applying daily 

gage height to rating table and interpolating for days of no gage heights, except for 

periods indicated in footnote to daily-discharge table. Records fair December to 

March because of meager data; good for remainder of year.

138 SURFACE WATER SUPPLY, 1917, PART XII B.

WILLOW CHEEK NEAR LENOX, IDAHO.

LOCATION. In sec. 1, T. 2 N., R. 5. E., 100 feet above extreme backwater from 

Arrowrock dam, three-eighths of a mile above mouth of creek, and 17 miles northwest of Lenox, Elmore County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 1, 1916, to September 30, 1917. A few discharge measurements were made by employees of United States Reclamation Service during 

the summer and fall of 1915.

GAGE. Graduations to feet and tenths chiseled on sloping face of granite boulder on 

right bank; read by S. F. Kesl. From November 19, 1915, to May 16, 1916, gage 

was 250 feet below, and consisted of graduations chiseled on two large lava boulders. No relation between the two gages.

DISCHARGE MEASUREMENTS. At low and medium stages made by wading; no equipment for high-stage measurements.

CHANNEL AND CONTROL. Bed composed of large boulders and rocks, with cobbles 

and sand; very rough. Rock in control probably permanent, but stage-discharge 

relation may be affected by scour and deposition of sand. Banks high. One 

channel at all stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 1.95 feet May 12 

(discharge, 234 second-feet); minimum stage recorded, 0.10 foot August 25 

(discharge, 0.5 second-foot). 

1916-1917: Maximum and minimum stages occurred in 1917.

ICE. Stage-discharge relation undoubtedly affected by ice, though observer made 

few notes.

DIVERSIONS. Many diversions made for irrigation from Willow Creek and Wood 

Creek above station.

REGULATION. None other than that due to effect of diversions.

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

well defined. Gage read to hundredths once weekly. Daily discharge ascertained by applying gage height to rating table and interpolating for days of no 

gage height, except for periods when stage-discharge relation was affected by 

ice, for which it was estimated. Records only fair because of infrequent gage

140 SURFACE WATER SUPPLY, 1917, PART XII B.

< 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-Arrowrock road, half a mile above mouth of creek, and 

5 miles southwest of Arrowrock.

DRAINAGE AREA. 426 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 1, 1914, to September 30, 1917; discharge measurements only prior to December 1, 1915.

GAGE. Graduations to feet and tenths chiseled on face of a rock ledge on left bank of 

stream and marked with white paint; read by A. P. Webb.

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

one-fourth of a mile below.

CHANNEL AND CONTROL. Bed consists of boulders, cobbles, and sand. Control 

shifts frequently owing to deposition of sand at low stages and cutting out at 

high stages. Stream usually carries much sand and silt as a result of placer operations in Boise Basin. One channel at all stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.65 feet on the 

morning of May 15 (discharge, 2,430 second-feet); minimum stage recorded, 0.86 

foot September 11 and 12 (discharge, 28 second-feet).

1915-1917: Maximum stage, 6.3 feet April 11, 1916 (discharge, 3,140 secondfeet); minimum stage recorded, 0.67 foot August 30, 1915 (measured discharge, 

17.8 second-feet).

ICE. Stage-discharge relation ordinarily not seriously affected by ice, prooably 

because of group of hot springs just above station.

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 are not great. Well-defined 

rating curves, based chiefly on previous season's measurements, were used during 

the year. On account of rough water, especially at the higher stages, it is difficult 

to read gage with refinement. Gage read to quarter-tenths once daily during 

high water and to hundredths during low-water period. Daily discharge ascertained by applying daily gage height to rating table and interpolating for days 

of no gage height. Records good.

COOPERATION. Several discharge measurements made by employees of United 

States Reclamation Service.

MA.LHETJB RIVER, AT WARM SPRINGS RESERVOIR SITE, NEAR RIVERSIDE. OREG.

LOCATION. In sec. 7, T. 23 S., R. 37 E., 500 feet above dam site of proposed Warm 

Springs reservoir, 2 miles south of Armstrong's house, 4 miles above mouth of 

South Fork, and 5 miles northwest of Riverside, Malheur County.

DRAINAGE AREA. About 1,100 square miles.

RECORDS AVAILABLE. December 9, 1914, to July 24, 1917, when station was discontinued. From January 3, 1906, to March 31, 1907, and from December 15, 1908, 

to May 25, 1910, records were obtained at a station about 4 miles below.

GAGE. Stevens continuous water-stage recorder on left bank; read by E. L. Armstrong. Staff gage about 200 feet above mouth of South Fork, used 1906 to 1910.

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

CHANNEL AND CONTROL. Gravel and small stones; likely to shift in floods. One 

channel for medium and high stages, but during low stages water crosses riffle 

in two or more channels.

EXTREMES OF DISCHARGE. Maximum stage from water-stage recorder, 4.60 feet at 

11.30 a. m. February 26 (discharge, 1,780 second-feet); minimum stage recorded, 

0.89 foot at 7 a. m. December 13 (discharge, 15 second-feet).

1906-1917: Maximum discharge, 5,490 second-feet for a stage of 10 feet on 

lower gage March 2,1910; minimum discharge, 2 second-feet August 5 to 30, 1909.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. A large area of bottom land is irrigated with flood water above this 

station.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during year; affected by ice December 5 to February 25. Rating curve used October 1 to April 12 fairly well defined 

between 5 and 100 second-feet and well defined between 100 and 1,500 second-feet; 

curve used April 13 to July 24 well denned above 150 second-feet and fairly well 

defined below. Gage read twice weekly during winter. Recorder operated 

satisfactorily October 1 to November 15 and February 26 to July 4. Daily 

discharge ascertained by applying to rating table mean daily gage height determined by inspecting recorder graph, except for period when stage-discharge 

relation was affected by ice, for which it was ascertained by means of discharge 

measurements, observer's notes, and weather records. Records good for October 

and March to July; fair for November; poor December to February.

146 SUEFACE WATEE SUPPLY, 1917, PAET XII B.

BULLY CREEK AT WARM SPRINGS, NEAR VALE, OREG.

LOCATION. In sec. 4, T. 18 S., R. 43 E., a quarter of a mile east of Warm Springs 

stage station on Vale-Westfall road, a quarter of a mile below mouth of Cottonwood Creek, and 14 miles west of Vale, Malheur County.

DRAINAGE AREA. 569 square miles (measured on Land office map).

EECORDS AVAILABLE. August 11, 1903, to March 10, 1904; January 24, 1905, to 

March 31,1907; January 1,1911, to May 31,1917, when station 'taas discontinued. 

Records are also available for a station about 12 miles below from April 8,1904, to 

December 31,1905.

GAGE. Two-section staff gage on left bank; upper section inclined, lower vertical; 

read by Walter Keele. Several gages have been in use at this station; they have 

been maintained at present datum since June, 1911, and probably since 1905.

DISCHARGE MEASUREMENTS. Made from cable or by wading.

CHANNEL AND CONTROL. Bed consists of coarse gravel; shifts during high stages. 

One channel at all stages. Stage-discharge relation seriously affected during 

summer by the heavy growth of aquatic plants in the channel.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 3.4 feet at 3 p. m. 

May 11 (discharge, 675 second-feet); minimum stage recorded, 0.85 foot October 

1 to 3 (discharge, 4 second-feet).

1903-1917: Maximum stage recorded, 8.6 feet March 1, 1910 (discharge, estimated from extension of rating curve, 6,240 second-feet). Creek dry March 19 

to 23, 1915, owing to water being held back by dam above; water standing in 

pools August 2 to September 15, 1911, and the discharge at gage during this and 

other periods probably zero.

ICE. Stage-discharge relation seldom affected by ice since dam was built above station.

DIVERSIONS. Numerous small ranch diversions are made both above and below the 

gage. The reservoir of the Vale-Oregon Irrigation Co. is about 3 miles above gage, 

but no diversions have yet been made into the company's canala.

REGULATION. Flow regulated to a certain extent by dam of Vale-Oregon Irrigation 

Co. since early part of 1915, the effect apparently being to increase the natural 

summer flow by storage and gradual release of flood waters.

ACCURACT. Stage-discharge relation remained practically permanent throughout 

year. Rating curve fairly well defined. Gage read to quarter-tenths once daily. 

Daily discharge ascertained by applying daily gage height to rating table. Records good except for February, for which month they are uncertain because 

only one daily gage reading was obtained during the high water on the 25th and 

26th, and for October and May, for which the use of the rating curve is doubtful.

WORTH FORK OF PAYETTE RIVER AT LARDO, IDAHO.

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

and outlet of Big Payette Lake. No tributaries entef between lake and gage.

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

RECORDS AVAILABLE. September 1, 1908, to June 30, 1917, when station was dis- 

* continued.

GAGE. Inclined staff on left bank installed July 25, 1911; read by Neal Boydstun. 

Original temporary gage (used Sept. 1 to Oct. 8,1908) was about 1 mile below site 

of present gage; permanent vertical staff gage (used until July 25, 1911) was 

installed October 14, 1908, on left bank about 30 feet below present site. 

datum unchanged since October 14, 1908.
148 SURFACE WATER SUPPLY, 1917, PART XII B.

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

CHANNEL AND CONTROL. Bed of stream and control consists of cobbles and gravel;

slightly shifting. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.6 feet June 20

(discharge, 2,980 second-feet); minimum stage recorded, 1.60 feet November

22-28 (discharge, 21 second-feet). 

1908-1917: Maximum stage recorded, 7.5 feet June 5, 1909 (discharge, 4,250

second-feet); minimum stage recorded, 1.1 feet October 21 and 22,1911 (discharge,

3 second-feet). 

ICE. Stage-discharge relation affected by ice, presumably because of the proximity

of the station to Big Payette Lake. 

DIVERSIONS. None above station. 

REGULATION . None. 

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

curve is based on measurements during 1919 and shape of previous curves, and is

well defined. Gage read to hundredths once daily for low stages and to halftenths and tenths for medium and high stages. Daily discharge ascertained by

applying daily gage height to rating table. Records fair, chiefly because no

measurements were made during year.

Daily discharge, in second-feet, of North Fork of Payette River at Lardo, Idaho, for the

year ending Sept. SO, 1917.

SOTTTH FORE OF BURNT RIVER AT HAHDMAN RANCH, NEAR UNITS', OREG.

LOCATION. In NW. J sec. 27, T. 13 S., R. 36 E., at ranch of J. R. Hardman, 8 miles 

southwest of Unity, Baker County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 13, 1916, to September 30, 1917.

GAGE. Vertical staff on upstream end of right abutment of private wagon bridge; 

read by O. M. Hardman.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Gravel; practically permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 1.7 feet May 15 

(discharge, 83 second-feet); minimum stage recorded, 0.70 foot October 1 to 13 

(discharge, 15 second-feet). 

1916-1917: Maximum and minimum stages occurred in 1917.

ICE. Stage-discharge relation never affected by ice.

DIVERSIONS. The Eldorado ditch diverts water from most of the tributaries of South 

Fork above station and carries it over Beam Creek divide into Willow Creek 

where it is used for irrigation. This ditch carried water during the spring until 

about July 1 but obtained most of its supply from streams which enter the river 

below the gaging station. The Fleetwood or Lancaster ditch diverts about 7 

second-feet past the gage during irrigation season.

REGULATION. None.

ACCURACY, Stage-discharge relation practically permanent. Rating curve well defined between 14 and 50 second-feet. Gage read to quarter-tenths once daily. 

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

The following discharge measurement was made by R. C. Briggs: 

July 30, 1917: Gage height, 0.82 foot; discharge, 21 second-feet.

slightly curved immediately above; one channel at all stages. Banks not subject 

to overflow. Control composed of large boulders 1,000 feet below gage; permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 18.6 feet June 18 

and 19 (discharge, 77,000 second-feet); minimum stage on November 15 when 

water was below gage, estimated at 0.8 foot (discharge, 2,500 second-feet).

1910-1917: Maximum stage recorded, 20.05 feet at 6 p. m. June 19, 1916 (discharge, 85,100 second-feet); minimum stage recorded on November 15, 1916.

ICE. Stage-discharge relation affected by ice during severe winters.

DIVERSIONS. Amount of water diverted for irrigation above station inconsiderable,

REGULATION. None.

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

Rating curve well defined. Gage read to hundredths twice daily. Daily discharge ascertained by applying mean daily gage height to rating table. Records 

excellent.

I TUCAHTHTOHT RIVER NEAR STARBTTCK, WASH.

LOCATION. In sec. 23, T. 12 N., R. 38 E., half a mile below Pataha Creek and 6 miles

east of Starbuck, 'Columbia County. 

DRAINAGE AREA. Not measured. 

RECORDS AVAILABLE. November 8, 1914, to September 30, 1917, when station was

discontinued.

GAGE. Inclined staff in two sections on left bank; read by Wesley and Oswald Martin. 

DISCHARGE MEASUREMENTS. Made by wading near gage or from bridge 1 mile

CHANNEL AND CONTROL. Bed composed of solid rock. Channel straight for 100 

feet above and below gage. Banks of light soil; wooded; left bank high; overflows right bank at gage height 5.5 feet. Control is vertical drop of 2 feet over. 

solid rock, 100 feet below gage. Stage-discharge relation affected by cutting low 

bank at bend at control and by building diversion dam below gage. Stage of 

zero flow, according to measurements made September 28, 1915, gage height 

0.60 ±0.1 foot.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.50 feet at 4 p. m. 

May 14 (discharge, 1,940 second-feet); minimum discharge, 58 second-feet September 2 and 9.

1914-1917: Maximum stage recorded, 8.5 feet at 7 p. m. February 10, 1916 

(discharge, 5,740 second-feet); minimum stage recorded, 1.60 feet August 24-31, 

1915 (discharge, 39 second-feet).

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Many small irrigation ditches divert water above gage; amount dir 

verted probably 10 per cent of usual flow during July and August. A large part 

of the diverted water seeps back to river above gage.

REGULATION . None.

ACCURACY. Stage-discharge relation affected by logs and varying amount of debris 

. on control October 1 to November 23; affected by ice November 12-19, December 

26 to January 1, and January 14-23; changed at medium high water April 26; 

affected by building of log and brush diversion dam below gage on or about July 

27. Rating curve used prior to change on April 26 well defined between 100 and 

1,500 Second-feet; curves used April 26 to July 26 and September 1-30 fairly well 

defined. Gage read to hundredths twice daily. Daily discharge ascertained 

by applying mean daily gage height to rating tables, except for period when 

stage-discharge relation was affected by ice for which it was ascertained by means 

of observer's notes and weather records. Shifting-control method used October 1 

to November 23. Discharge for July 27-31 and monthly mean discharge for August, when stage-discharge relation was affected by varying amount of backwater 

from diversion dam, estimated by hydrographic comparison with flow of Mill 

Creek near Walla Walla. Records good except for periods noted when stage discha^rge was affected by backwater from ice or varying amount of debris on control.

TRIBUTARY BASINS.

PALOUSE RIVER HEAR WINONA, WASH.

LOCATION. In sec. 5, T. 16 N., R. 39 E., 1,000 feet below Rock Creek, 7 miles southwest of Winona, in Whitman County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. December 16, 1914, to September 30, 1917, when station was 

discontinued.

GAGE. Inclined staff on right bank; installed November 30, 1915; read by Theodore 

McDougall. Prior to November 30, 1915, inclined and vertical staff on right 

bank about 200 feet below Rock Creek.

DISCHARGE MEASUREMENTS. Made from cable at gage or by wading. 2

CHANNEL AND CONTROL. Bed composed of gravel; shifting. Right bank high; left 

bank subject to overflow at high stages. Stage of zero flow, according to measurements made October 8, 1917, gage height 0.60 foot ±0.02 foot.

EXTREMES op DISCHARGE. Maximum stage recorded during year, 12.9 feet from highwater mark, between 5. p. m. April 8 and 5 p. m. April 9 (discharge, il,800 

second-feet); minimum stage recorded, 1.43 feet September 27 (discharge, 14 

second-feet).

1914-1917: Maximum stage occurred in 1917; minimum stage recorded, 0.48 

foot September 27, 1915 (discharge, 9 second-feet).

ICE. Stage-discharge relation affected by ice during severe winters.

DIVERSIONS. Several irrigation ditches divert water above gage; though individually 

small they probably take in the aggregate a large proportion of the extreme lowwater flow.

REGULATION. Flow slightly regulated by splash dams in Idaho.

ACCURACY. Stage-discharge relation changed during high water February 6; not 

affected by ice. Rating curve used prior to change well defined; curve used 

after change well defined below and fairly well defined above 1,500 second-feet. 

Gage read to hundredths once daily. Daily discharge ascertained by applying 

daily gage height to rating table, except for days of no gage reading for which it 

was interpolated. Records good.
