SURFACE WATER SUPPLY OF SNAKE RITFB 

BASIN, 1915.

AtTTHOBIZATION AND SCOPE OF

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

measurements of flow'made on streams in the United State** during 

the year ending September 30,1915.

The data presented in these reports were collected by thr United 

States Geological Survey under authority implied in the organic law 

(20 Stat. It., pi 394), which contains the following paragrapl:

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

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

The work was begun in 1888 in connection with special studies of 

water supply for irrigation. 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 streama^and determining the water supply of the United £ *ates, and 

for the investigation of underground currents and artesian wells, and for th* preparation of reports upon the best method's of utilizing the water resources.

In the execution of the work many private and State organizations 

have cooperated, either by furnishing data or by assisting in collecting data. Acknowledgments for cooperation of the first kind are 

made in connection with the description of each station affected; 

cooperation of the second kind is acknowledged,on page 13.

Measurements of stream flow have been made at, about 3 $00 points 

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

Hawaiian Islands. In July, 1915, 1,350 gaging stations we^e being 

maintained by the Survey and the cooperating organisations. Many, 

miscellaneous discharge measurements were made at other points;,

8 SURFACE WATEE SUPPLY, 1915, PART XII B.

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 time 

Information in regard to publications relating to water resources is 

presented in the appendix to this report.

DEFINITION OF TERMS.

The volume of water flowing in a strtam the "run-off" oi* "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 depth hi inches, acre-feet, and1 millions of 

cubic feet. The principal terms used in this series of reports are 

second-feet, second-feet per square mile, run-off hi inches, and acrefeet. 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 by the use of the factors given 

in the tables of convenient equivalents (pp. 9-40), -

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

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

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

regards time and area.

"Run-off depth 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 runoff with rainfall, which is usually expressed in depth of 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 ar$ here defined:

"Stage-discharge relation," an abbreviation for th^ expression 

"relation of gage height to discharge."

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

the stream below the gage which determine the stage-discharge relation at the gage. It should be noted that the control may not be the 

same section or sections at all stages.

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

gage the gage height to which tjbe surface of the river would' 

fall if there were no flow.

BXPLANATTON OF DATA.

The data presented in. this report cover the year beginning October 

1, 1914, and ending September 30, 1915. At the 1st of Jarnary in 

most parts of the United States much of the precipitation in the preceding three months is stored as ground water, in the form of enow 

or ice, or in ponds, lakes, and swamps, and this stored wate"* passes 

off in the streams during the spring break-up; at the end of September, on the other hand, the only stored water available for run-off 

is possibly a small quantity in the ground; therefore the rur^-off for 

the year beginning October 1 is practically all derived from precipitation within that year.

The base data collected at gaging stations consist of records of 

stage, measurements of discharge, and general information used to 

supplement the gage heights and discharge measurements in determining the daily flow. The records of stage are obtained eitl *ac from 

direct readings on a staff or chain gage or from a water-stage recorder that gives a continuous record of the fluctuations. l*easurements of discharge are made-with a current meter by the general 

methods outlined in standard textbooks on the measurement of river 

discharge. (See Pis-. I and II.)

From 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 

and yearly mean discharge is determined. ,
12 SURFACE WATEE SUPPLY, 1915, PART XII B.

The data presented for each gaging station in the ares, 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 dailj discharge, 

tables giving daily gage heights and results of discharge measurements 

are published.

The description of the station gives, in addition to statements 

regarding location and equipment, information in regard to any conditions that may affect the constancy of the stage-discharge relation, 

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

for log driving, shifting of channel, and the ea"us"e ant! effect of backwater; it gives also information as to diversions that decrease the 

flow at the gage, artificial regulation, maximum an'i minimum 

recorded stages, 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. . When such 

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 vas at crest 

height and the corresponding discharge was consequently -larger than 

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

" Minimum," the quantity given ia the mean flow for tit * d-ay when 

the mean , gage height wa^ lowest, The column headed' '-Bfean" is 

the average $ow ia cubic feet for-eacli second during the month. On 

this average flow" computations recorded in the remaining columns,- 

which are defined on page. 8, are based.

ACCURACY OF FIEIJ> DATA AND COMPUTED

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

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

of observations of stage, measurements of flow, and interpretation. 

of records. . .

Foot-notes added to1 the daily-discharge tables give information 

regarding the probable accuracy of the rating tables used, and an

accuracy column is inserted in the monthly-discharge t&Mev ' For the 

rating tables, "well defined" indicates, in general, that? the trying 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 letter in/the column headed "Accuracy," in the montl ly-Mlischarge table, rates the accuracy of the monthly mean and not that 

of the estimate-of maximum or minimum discharge or the discharge 

for any one day. The rating is determined by considering the accuracy of the rating curve, the probable reliability of the observer, the 

number of gage readings per day, the range of the fluctuation ir stage, 

and local conditions. In this column A indicates that determination 

of the mean monthly flow is probably accurate within 5 per ciait; B, 

within 10 per cent; C, within 15 per cent; D, within 25 peM cent. 

Special' conditions are covered by footnotes.

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 inch«ts may 

be subject to grdss errors caused by the inclusion of large noncontributing districts in the measured drainage area, by lack of information concerning water diverted for irrigation or other use or by 

inability to interpret the effect of artificial regulation of the flow of 

the river above the station. "Second-feet per square mile" and 

"run-off (depth in inches) " t are therefore not computed if sue! errors 

appear probable. Tlie computations are also omitted for stations on 

streams draining areas in which the annual rainfall is less tVan 20 

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

"run-off - (depth 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, 1915, work In the Snake 

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

Orejgon, 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. The State of Idaho, however, furnished no funds for the 

cooperative work after November 30, 1914. ' " -

20 SURFACE WATER SUPPLY, 1915, PARtf XII B.

SNAKE RIVER. NEAR HEISE, IDAHO.

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

Bonneville County, 3 miles above Heise and 25 miles below the station formerly 

maintained near Lyon. Several small creeks enter between the two stations.

DRAINAGE ABBA. Not measured.

RECORDS AVAILABLE. September 25, 1910, to September 30, 1915.

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

to vertical staff gage. Observer, Parley Byington.

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

CHANNEL AND CONTROL. Bed composed of coarse gravel and cobbleot two channels 

at low and medium stages. Control formed by crest of Andersor dam, which is 

a fairly permanent crib and rock structure. Stage-discharge relation affected at 

times by repair work on dam and injury to crest caused by ice ?nd high water.

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

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

recorder, 6.15 feet at 4 a. m. June 28 (discharge, 17,100 second-foet); minimum 

stage recorded, 1.1 feet at 10 a. m. March 10 (discharge, 2,180 seccnd-feet).

1910-1915: Maximum stage recorded, 10.35 feet on June 16 and 17, 1911 (discharge, 36,000 second-feet) ; minimum stage March 10, 1915.

DIVERSIONS. No large diversions above station. Small ditch of about 20 secondfeet capacity diverts just above the station.

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

reservoir.

ACCURACY. Stage-discharge relation practically permanent except when affected 

by ice. Rating curve well defined between 2,200 and 27,000 secon d-feet. Waterstage recorder not in operation continuously and one reading a day was obtained 

on staff gage except December 9 to February 21. Daily discharge ascertained 

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

22 SURFACE WATER SUPPLY, 1915, PART XII T

SNAKE RIVER NEAR SHELLEY, IDAHO.

LOCATION. In sec. 17, T. 1 N., K. 37 E., about one-fourth mile upstream from the

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

DRAINAGE AREA. Not measured.

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

GAQE. Friez water-stage recorder on right bank; standard hook gf*re in float well,

and combination vertical and inclined staff gage outside. James Fugal, observer. 

DISCHARGE MEASUREMENTS. Made from the Woodville bridged 

CHANNEL AND CONTROL. Control is a lava rock reef extending across the channel

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

WINTER FLOW. Stage-discharge relation probably seriously affecte'1 by ice. 

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

9.6 feet at 9 p. m. June 4 (discharge, 15,400 second-feet); minimum stage from

recorder, 4.88 feet at 4 a. m September 2 (discharge, 1,800 secoid-feet). 

DIVERSIONS. Numerous diversions in the Idaho Falls district above the station

appropriate practically the entire normal summer flow of the river. 

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

of stored flood waters from Jackson Lake for use on Minidoka project. 

ACCURACY. Stage-discharge relation practically permanent. Ratir? curve referred

to hook gage well denned between 1,900 and 12,000 second-feet. Daily discharge

ascertained by applying to rating table mean daily gage heights determined by

inspection of gage-height graph. Records good.

SNAKE RIVER NEAR BLACKFOOT, IDAHO.

LocATioN.---In sec. 31, T. 3 S., R. 34 E., about one-fourth mile below mouth of Blackfoot River and 14 miles southwest of Blackfoot, Bingham County. Blackfoot 

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

Fork, about 60 miles above. Portneuf and Bannock rivers, together with about 

2,500 second-feet of spring water, enter between this station and that e.t Neeley.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. June 6, 1910, to September 30, 1915.

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

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

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

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

staff was installed. Observer, James A. Clough.

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

wading.

CHANNEL AND CONTROL. Bed composed of very coarse gravel; two channels at low 

and three at medium stages. Control shifts slightly during high water but was 

permanent during 1915.

WINTER FLOW. Floating ice sometimes present for short periods; stage-discharge 

relation apparently not affected.

EXTREMES OF DISCHARGE. Maximum stage recorded during year 8.55 feet at 6 a. m. 

June 5 (discharge, 15,800 second-feet); minimum stage recorded, 1.98 feet at 

5 p. m. July 27 (discharge 388 second-feet).

1910-1915: Maximum stage recorded 12.63 feet at noon June 8, 1914 (discharge 

35,600 second-feet); minimum stage 1.89 feet August 11 and 15, 1910 (discharge, 

238 second-feet).

DIVERSIONS. Practically all the natural summer flow diverted above the station,

REGULATION. Flow regulated by storage in Jackson Lake reservoir and also by 

storage in Blackfoot-Marsh. reservoir on Blackfoot River. Practically all of 

present summer flow is released water from these reservoirs.

ACCURACX. Stage-discharge relation permanent during year. Rating c^rve well 

defined between 400 and 20,000 second-feet. Operation of water-stags recorder 

satisfactory except as noted in footnote to table of daily discharge. Discharge 

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

inspection of gage-height graph October 1 to July 19, August 4 to 28, and September 13 to 30; July 20 to August 3, gage heights derived from graph drawn 

through daily staff-gage readings; August 29 to September 12 gage height^ obtained 

by one reading a day. Records good throughout year.

SNAKE BIVER BASIS'. 27

SHAKE RIVER AT NEELEY, IDAHO.

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

County, 4 miles southwest of American Falls, and about 32 miles above the Minidoka dam. Portneuf and Bannock rivers and about 2,500 second-feet of spring 

water enter Snake River between the Blackfoot gaging station and Neeley. Raft 

River enters about 18 miles below Neeley.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 17, 1906, to September 30, 1915.

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

staff gage originally used.

DISCHARGE MEASUREMENTS. Made from cable at gage.

CHANNEL AND CONTROL. Control is of lava rock, probably partly overlain with 

coarse gravel; permanent during 1915. Bed of river at measuring section is 

rough, especially near right bank. Both banks are high and clean. One channel 

at all stages.

WINTER PLOW. Stage-discharge relation seriously affected by ice durng parts of 

December and January; flow estimated principally by comparison with the 

record of flow at the Blackfoot station.

EXTREMES OP DISCHARGE. Maximum stage during year from water-sta^e recorder, 

8.22 feet at 11 p. m., June 6 (discharge, 17,400 second-feet); minimum stage, 

3.98 feet at 9 p. m., July 26 (discharge 2,750 second-feet).

1906-1915: Maximum stage recorded, 12.5 feet June 11, 1909 (disci <*rge, 41,100 

second-feet); minimum stage recorded, 3.65 feet August 20-22, 190f (discharge, 

2,220 second-feet).

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

practically the entire natural summer flow of Snake River.

REGULATION. The summer flow at this station is augmented by stored water from 

Jackson Lake for use on the Minidoka project, and also by stored water from the 

Blackfoot-Marsh reservoir.

ACCURACY. Stage-discharge relation permanent during year except wl ?n affected 

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

except for short periods as noted in foot-note to table of daily discharge. Discharge ascertained by applying to rating table mean daily gage heights obtained by 

inspection of gage-height graph (for exceptions see footnote to table of daily 

discharge). Records fair for December; good for rest of year.

SNAKE BIVER BASIN. 29

SNAKE RIVER NEAR MINIDOKA, IDAHO.

LOCATION. M sec. 2, T. 9 S., R. 25 E., 100 yards below HowBlFs ferry, 1 r^ile below 

the Reclamation Service dam, 6 miles southeast of Minidoka post ofrce, Minidoka County, the nearest railroad point, and about 6 miles above the Mor+^omery's 

ferry station, which waa discontinued December 31, 1910. Raft Rrrer enters 

between the stations at Neeley and Minidoka.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 21, 1910, to September 30, 1915.

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

at same datum as staff gage used prior to August 28, 1911; also Stevers long-distance recorder installed April 1, 1915. G. H. Home, observer.

DISCHARGE MEASUREMENTS. Made from cable about 50-feet below the gaje.

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

Control shifts slightly but infrequently.

WINTER FLOW. Some shore ice appears in vicinity of gage; stage-discharge relation 

belieyed to have been unaffected during winter of 1914-15.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 10.90 feet from 

4 to 5 p. m., November 15 (discharge, 21,800 second-feet); minimuir stage recorded, 4.05 feet from 11 a. m. to 3 p. m. October 13 (discharge, 960 se?ond-feet). 

1910-1915: 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).

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

Neeley and Minidoka stations (see pp. 81-84). The nearest diversions below the 

station are the Twin Falls North Side and South Side canals at JfiBner (see pp. 

90-94).

REGULATION. Flow entirely regulated by storage above Minidoka dan (storage 

capacity, 54,000 acre-feet).

ACCURACY. Stage-discharge relation changed somewhat between January 28 and 

March 30. Rating curves well denned. Operation of water-stage recorder 

satisfactory except for short periods during the winter months. From October 

to March repairs were being made to the spillway and tailrace at the dam and 

water was stored during the day and released at night; discharge for practically 

all days during this period determined hourly. See note to table of daily discharge. Records good except for December.

COOPERATION. United States Reclamation Service furnished gage-heifht record 

and made two discharge measurements.

NOTE. All readings from staff gage.

SNAKE RIVER AT MILNER. IDAHO.

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

Milner, Twin Falls County. No tributaries enter Snake River between the Minidoka station and Milner, and no important amount of water between Milner and 

the station near Twin Falls, except some seepage and spring water.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 10,1909, to September 30,1915.

GAGE. Staff gage in three sections, high and low sections vertical, and mHdle inclined, on left bank, installed Oqtober 20, 1909; read by F. W. Deming October 1 

to June 26 and by T. R. Newell, June 27 to September 30. An auxiliary lowwater gage is installed on the right bank about 100 yards below the main gage, to 

which it bears no definite relation. The original gage used prior to October 20, 

1909, was a vertical staff on the right bank at approximately the same dHum as 

tiie present gage.
32 SURFACE WATER SUPPLY, 1915, PART XII B.

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

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

the suspension highway bridge one-fourth mile below the main ga#e, but the conditions there are poor.

CHANNEL AND CONTROL. Control for main gage is an old erib-and-rocV diversion dam 

and is practically permanent for medium and high stages. Bed of the stream 

both at the main gage and at the auxiliary gage consists of lava rock, which also 

forms the control for the low-water gage.

WINTER FLOW. Stage-discharge relation not seriously affected by i~e; open water 

rating assumed applicable; observations are, however, discontinued during part 

of winter as gages are at times inaccessible.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 16.3r feet at 8 a. m., 

November 15 (discharge, 20,400 second-feet); minimum stage recorded, 1.08 feet 

(on auxiliary gage) August 17 and 18 (discharge, 9 second-feet).

1909-1915: Maximum stage recorded, 20.1 feet June 12, 1909 (d ^charge, 44,400 

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

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

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

station. During part of the season practically the entire flow of tl 9 river is taken 

by these canals.

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

Milner dam.

ACCURACY. Stage-discharge relation practically permanent during the year. Gage 

read to hundredths once daily, October 1 to June 26, and twice daily June 27 to 

September 30. Discharge ascertained by applying mean daily gage heights to 

rating table. Records good except for April and May when gage was not read regularly.

COOPERATION. Gage-height record furnished by the Twin Falls Cam-1 Co., some discharge measurements by special assistant to State engineer stationed at this 

station.

34 SURFACE WATER SUPPLY, 1915, PART XH T 

SNAKE RIVER NEAR TWIN FALLS, IDAHO.

LOCATION. In sec. 33, T. 9 S., R. 17 E., at Perrine's bridge on the I. B. Perrine Blue 

Lakes ranch, about 4 miles north of the city of Twin Falls, Twin Falls County, 

and 4 miles below Shoshone Falls. The outlet of the Blue Lakes enters Snake 

River about 200 feet below the gage, and Salmon Falls Creek enters about 18 

miles below.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 29, 1911, to September 30, 1915.

GAGE. Inclined staff on left bank, about 100 feet above the bridge; re*d by employees 

of I. B. Perrine.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Control consists of lava boulders and solid rock, permanent. 

Bed of river at measuring section is very rough. Banks are higl and not subject 

to overflow.

WINTER PLOW. Stage discharge relation not seriously affected by ice; open channel 

rating curve assumed applicable.

EXTREME OP DISCHARGE. Maximum stage recorded during year, 10.6 feet at 7 a. m., 

November 16 (discharge, 21,500 second-feet); minimum stage recorded, 2.05 feet 

June 27, 29, and 30, July 1-4, 9-16, 18-20, 28-29, and 31; August 1-3, and 6, 7 

(discharge, 468 second-feet).

1911-1915: Maximum stage recorded, 13.3 feet at 6 a. m. and 7 p. m., June 10, 

1914 (discharge, 32,200 second-feet); minimum stage recorded, 2.05 feet, June 27, 

29, and 30, July 1-4, 9-16, 18-20, 28-29, and 31, August 1-3, ard 6-7, 1915 (discharge, 468 second-feet).

DIVERSIONS. No diversions are made from the river between this station and the one 

at Milner except small ranch ditches.

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

South side canals at Milner, where practically the entire flow of the river is diverted during 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 disci irge ascertained 

by applying mean daily gage heights to rating table. Records of monthly discharge excellent though parts of the records of daily discharge may be somewhat 

in error as a result of diurnal fluctuations due to operation of gate-" at Milner dam.

SNAKE RIVER NEAR HAOERMAK, IDAHO.

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

Falls, and about 5 miles south of Hagerman, Gooding County. Big Wood River 

enters about 10 miles below.

DRAINAGE AREA. Not measured.

 RECORDS AVAILABLE. August 24, 1912, to September 30,1915.

GAGE. Vertical staff on left bank about 50 feet below the ferry; installed August 15, 

1915, at same location and datum as former inclined gage. Gage No. 2 read 

by Clarice Owsley. An auxiliary inclined staff is also maintaired at the site of 

a proposed power house If miles below.

DISCHARGE MEASUREMENTS. Made from cable about 150 feet above gage.

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

WINTER FLOW. Stage-discharge relation not affected by ice; op^n-water rating 

curves are applicable throughout winter.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 6.3 feet at 7.20 

a. m. November 16 (discharge, 23,100 second-feet); minimum stage recorded, 

3.1 feet July 15 to August 2 (discharge, 4,030 second-feet).

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

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

DIVERSIONS. No diversions of importance between this station anc? that at Milner. 

Practically entire flow of the 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 up th-i river.

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

ACCURACY. Stage-discharge relation practically permanent dunn-? year. Bating 

curve well denned. Gage read to quarter tenths twice daily. Discharge ascertained by applying mean daily gage heights to the rating table, Records food 

except for a few days when gage heights are questionable.

38 SURFACE WATER SUPPLY, 1915, PART XH B. 

SNAKE RIVER AT KING THTT.T., IDAHO.

LOCATION. In sec. 7, T. 5 S., R. 11 E., about 300 feet east of the Orepon Short Line 

Railroad station at King Hill, Elmore County. Big Wood River enters from the 

north about 20 miles above the station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 13, 1909, to September 30,1915.

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

staff on the left bank at practically the same section as the present gage, but with 

datum about 2.2 feet higher. Temporary staff gage about three-fourths mile above 

present location used March 7 to August 16, 1910.

DISCHARGE MEASUREMENTS. Made from cable about 100 feet below g"»ere.

CHANNEL AND CONTROL. Bed at the gage and measuring section cor<t>osed largely 

of gravel. The control is a lava reef partly overlain with gravel; shifts slightly.

WINTER FLOW. Stage-discharge relation unaffected by ice; open-channel ratings 

applicable throughout winter.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 11.6 feet at 2.56 

p. m. November 16 (discharge, 26,300 second-feet); minimum etage recorded, 

5.1 feet June 27 and 29 (discharge, 5,740 second-feet).

1909-1915: Maximum stage recorded, 13.1 feet June 12 and 13, 1909 (discharge, 

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

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

DIVERSIONS. No important diversions for irrigation are made between the Milner 

station and King Hill.

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 changed slightly during the year. Rating 

curves well denned. Gage read to quarter tenths daily. Discharge determined 

by applying daily gage heights to several rating tables during year. Records 

good.

40 SURFACE WATER SUPPLY, 1915, PART XII B. 

SNAKE RIVER NEAR MURPHY, IDAHO.

LOCATION. In the NW. J sec. 18, T. 2 S., B. 1 E., three-fourths rfile below the 

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

Murphy. The gage is on the Ada County side of the river and is 38 miles below 

the mouth of Bruneau River.

DRAINAGE ABBA. 41,900 square miles (measured on United States Lan-* Office maps).

RECORDS AVAILABLE. August 21,1913, to September 30, 1915.

GAGE* Friez water-stage recorder on right bank one-fourtht mile below house of 

S. H. Gantwell; installed September 7, 1914. Temporary vertical staff first 

installed at this site August 29,1912, was replaced October 2,1912, by an inclined 

staff, and a vertical low-stage section was added August 22, 1913. Temporarily 

installed water-stage recorders were in operation December 13, 1913, to June 27, 

1914. All gages at practically the same location and set to the same datum. 

Records prior to August 21, 1913, fragmentary.

DISCHARGE MEASUREMENTS. Made from ferryboat 1£ miles above the gage.

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

silt, and gravel, where not scoured out by the current. Control practically 

permanent; banks not subject to overflow.

WINTER PLOW. Stage-discharge relation not affected by ice.

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

8.52 feet at 2 p. m. November 17, 1914 (discharge 25,600 second-fe3t); minimum 

stage not definitely determined but less than 1.45 feet on several occasions 

during manipulation of gates at the power plant. Minimum mean daily stage, 

 1.2 feet July 17 and 23 (discharge 5,560 second-feet).

1912-1915: Maximum stage recorded 12.13 feet at 11.30 a. m, June 10, 1914 

(discharge 39,600 second-feet); minimum stage as noted for current year.

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 due to the manipulation of 

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

of the small amount of storage obtained at the dam the change* are of short 

duration.

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

defined. Operation of water-stage recorder satisfactory except as noted in footnote to table of daily discharge. Daily discharge determined by applying to 

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

Records good.

COOPERATION. Gage-height record furnished by Electric Investment Co., formerly 

the Idaho Railway Light & Power Co.

The following .discharge measurement was made by A. W. Harrington: 

May 10,1915: Gage height, 1.70 feet; discharge, 3,780 second-feet.

second-feet; May 24-28,12,300 second-feet; June 7 and 8,17,000 second-feet. During parts of certain days 

in July_, Aug., and Sept., stage fell below range of recorder, owing to manipulation of gates at r°wer house, 

but this fluctuation affected accuracy of daily discharge record but slightly.

SNAKE RIVER AT WKISER, IDAHO.

LOCATION. In sec. 31, T. 11N., E. 5 W., about one-third of a mile above wagon bridge

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

Succor Creek and Owyhee and Malheur rivers enter Snake River on the left bank

and Boise, Payette, and Weiser rivers on the right bank. 

DRAINAGE AREA. Not measured. 

RECORDS AVAILABLE. October 8, 1910, to September 30, 1915. Fragmentary record

of gage heights 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. Control fairly

permanent. One channel at all stages. 

WINTER PLOW. Stage-discharge relation not seriously affected by ice; open channel

rating curve used throughout the year. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.4 feet at 8 a. m.,

November 18 (discharge 28,600 second-feet); minimum stage, 1.5 feet at 8 a. m.,

August 28 and 29 (discharge 5,550 second-feet).

1910-1915: Maximum stage recorded, 14.5 feet (U. S. G. S. 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). 

DIVERSIONS. Some water diverted between Weiser and station near Murphy but

almost entirely by pumping. 

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

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

applying daily gage heights to rating table. 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,

1915.

44 SURFACE WATER SUPPLY, 1915, PART XII B.

SNAKE RIVER NEAR BT7RBANK, WASH.

LOCATION. In sec. 28, T. 9 N., R. 31 E., at the head of Fivemile Rapids, abo*» 

intake of Burbank Power & Water Co. 's canal, 4 miles above Burbrnk, in Wafla 

Walla County.

DRAINAGE AREA. 109,000 square miles (measured on General Land Office and 

Forest Service maps).

RECORDS AVAILABLE. September 1, 1909, to September 30, 1915; fragmentary 

records October 2, 1907, to August 31, 1909.

GAGE. Inclined staff 1,500 feet above canal intake; datum 300 feet above sea level; 

auxiliary vertical staff at lower end of power canal. Gage read daily by Harry 

Phelps, Lewis Dunlap, and E. B. Madden.

DISCHARGE MEASUREMENTS. Made from Northern Pacific Railway bridge at Burbank, 4 miles below gage.

CHANNEL AND CONTROL. Control at head of rapids; may shift at flood stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 42.6 feet May 20 

and 21 (discharge, 122,000 second-feet); minimum stage recorded, 34.6 feet September 1 and 2 (discharge, 13,000 second-feet).

1909-1915: Maximum stage recorded, 51.8 feet May 29, 1913 (disci arge, 298,000 

second-feet, revised); minimum stage recorded, 34.6 feet September 4, 1914 

(discharge, 13,000 second-feet, revised).

WINTER PLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. A large amount of water is diverted from Snake River for irrigation in 

southern Idaho. x

STORAGE. Jackson Lake reservoir (capacity, 400,000 acre-feet) is the largest in 

operation.

ACCURACY. Stage-discharge relation practically permanent during the year; not 

affected by ice. Rating curve well defined below 225,000 second-feet. Gage 

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

heights to rating table. Records excellent for periods in which regular gage was 

read, good for thos6 in which readings were obtained from gage in power canal, 

and fair when based partly on hydrographic comparison with records of flow at 

Lewiston and Riparia. See footnote to table of daily discharge.

COOPERATION. Gage-height record furnished by the Burbank Co.

LOCATION. In sec. 30, T. 6 N., R. 39 E., Madison County, just below higirvay bridge 

about a mile below mouth of south channel of Teton River, 7 miles below main 

channel of Teton River, and 7 miles due west of Rexburg; below all tributaries.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 13, 1909, to September 30, 1915. ' GAGE. Friez water-stage recorder on right bank about 250 feet below br'dge; prior 

to April 5, 1913, vertical staff on right bank about 25 feet farther downstream. 

Datum of gages used before January 1, 1912, 0.67 foot higher than that of present 

gage. F. P. Hansen, observer.

DISCHARGE MEASUREMENTS. Made from cable about one-fourth mile b^low gage, 

from highway bridge above gage, or by wading.

CHANNEL AND CONTROL. Bed composed of mud, sand, and fine grave?: shifting. 

Except at the bridge left bank is overflowed at high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded, 8.90 feet at 7 a. m. June 4 

(discharge, 6,200 second-feet); minimum stage, 1.90 feet at 6 p. m. August 10 

(discharge, 481 second-feet).

1909-1915: Maximum stage recorded, 8.7 feet (equal to 9.37 feet present datum) 

June 6 and 7, 1909 (discharge, 7,680 second-feet); minimum stage recorded, 

August 10, 1915.

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

DIVERSIONS. Irrigation canals divert water above station but definite mformation 

as to number of canals and quantity of water diverted is not available.

REGULATION. None except that due to opening or closing head gates of irrigation 

canals.

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

October 1 to June 4 (except during winter) and September 10-30. Sfean daily 

gage heights obtained by inspecting gage-height graph. Daily discharge ascertained by applying mean daily gage heights to rating table except June 5 to 

September 9, for which period shifting-control method was used. Records good.

IDAHO (GOVERNMENT) CANAL NEAR SHELLEY, IDAHO.

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

head gatea, 1J miles southwest of Shelley, and 10 miles above point vhere Sand

Greek crosses canal. 

RECORDS AVAILABLE. June 20, 1912, to September 30, 1915. No water diverted

during 1913 because of break in canal. 

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

Hanks. Bristol water-stage recorder operated during previous season-": inclined

staff alwaya used as reference gage. 

DISCHARGE MEASUREMENTS. Made by wading or from suspension footbridge about

3 feet below gage. 

CHANNEL AND CONTROL. Trapezoidal concrete rating section. Collection of brush

and growth of aquatic plants cause changes in stage-discharge relation, but bottom

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

on gage. 

EXTREMES OF DISCHARGE. Maximum stage recorded during the year, 2.83 feet at

1.30 p. m. August 5; maximum discharge at gage height 2.7 feet June 28 (discharge,

142 second-feet); minimum flow practically zero probably about 0.0 on gage but

has not been definitely determined as no records are kept when head gatea are shut

down.

1912-1915: Maximum stage recorded, 3.7 feet July 29, 1912 (discharge, 308

second-feet); minimum as stated in preceding paragraph. 

WINTER FLOW. Canal not operated during winter.

1908-1915: Maximum stage recorded, 4.15 feet May 14, 1909 (discharge, 1,640 

second-feet); minimum stage recorded January 21, 1915.

WINTER PLOW. Stage-discharge relation not affected by ice; owing to proximity of 

station to reservoir, channel remains open.

DIVERSIONS. Only a few small diversions are made fqr irrigation from river and 

tributaries above reservoir.

REGULATION. Flow controlled by gates at dam.

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

well-defined rating curves used, one applicable October 1 to February 4, the other 

February 5 to September 30. Recorder not in operation October 1 to March 31; 

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

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

by applying daily gage heights to rating table. Records good.

all important tributaries.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE . June 26, 1909, to September 30, 1915. From April 17, 1903, 

to December 31, 1909, records were obtained near Presto, about 5 mil<v3 below 

site of present station; no tributaries enter between the two sites, but during the 

irrigation season several ditches divert probably 50 second-feet.

GAGE. Friez water-stage recorder on right bank; observer, Rufus E. Reid.

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

somewhat shifting.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 5.50 feet at 2.30 

p. m. June 26 and 2 p. m. July 3 (discharge, 1,120 second-feet); minimum stage 

recorded, 3.33 feet at 3 p. m. February 12 (discharge, 85 second-feet). Lower 

stages may have occurred during January or the first part of February, when the 

stage-discharge relation was affected by ice.

1909-1915. Maximum stage recorded, 5.80 feet at 11.45 p. m. AprT 1, 1913 

(discharge, 1,370 second-feet); minimum stage recorded about 3.1 feet I member 

29, 1911 (discharge, 45 second-feet)..

WINTER FLOW. Stage-discharge relation seriously affected by ice; flow estimated 

from discharge measurements and comparison with record of flow at station near 

Henry.

DIVERSIONS. No important diversions from river or tributaries above statior.

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

of the United States Indian Service, about 40 miles upstream.

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

January, and February. Rating curves well defined by measurements except 

during winter months. Mean daily gage heights obtained by inspecting recorder graph. Daily discharge, except for periods during which stage-discharge 

relation was affected by ice, ascertained by applying daily gage heights to rating 

table. Records good.

LITTLE BLACKFOOT RIVER AT HENRY, IDAHO.

LOCATION. In sec. 10, T. 6 S., R. 42 E., on Skinner's ranch, at Henry, Bannock 

County, a short distance above flow line of Blackfoot-Marsh reservoir.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE.-.-March 24, 1914, to September 30, 1915.

GAGE. Vertical staff fastened to log across stream just below Skinner's barn. Read 

by Beatrice Skinner.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Bed composed of rock, sand, and gravel. Control is rock 

crest of an 8-foot falls. Stage-discharge relation affected by growth of aquatic 

plants during large part of year.

WINTER PLOW. Stage-discharge relation not affected by ice; channel kept open by 

warm springs.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 2.6 feet at 7 p. m., 

April 6 (discharge, 124 second-feet); minimum stage, 1.33 feet Jrnuary 1 and 3 

(discharge, 11 second-feet). Minimum discharge may have occurred in August. 

1914-15. Maximum stage recorded, 3.5 feet at 8 p. m., April 19,1914 (discharge, 

determined from extension of rating curve, about 292 second-foet); minimum 

stage, 1.20 feet March 24, April 1 and 2, and from 6 p. m., July 4, to July 7, 1914; 

minimum discharge, determined by shifting-control method, 6.9 feet July 5, 6, 

and 7, 1914.

DIVERSIONS. A ditch for watering stock takes out about 300 feet above station arid 

a small ditch diverts water from the warm springs that enter the river between 

station and reservoir.

REGUJLATION . None.

ACCURACY. Stage-discharge relation affected by growth of aquatic plarts, but changes 

up to July 23 are well denned by measurements. Rating curve fairfy well defined 

January 22 to April 30. Gage read to hundredths twice daily. Daily discharge 

ascertained by applying daily gage heights to rating table January 22 to April 30 

and by shifting-control method for rest of year except October J.-3 and July 24 

to September 28. Records fair, except those for July 23 to September 30, which 

are poor.

62 SURFACE WATER SUPPLY, 1915, PART XII B

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-fourths mile below Goose Lake or Pelican Slough, and 1$ miles 

northeast of Henry, Bannock County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 17, 1914, to September 30, 1915.

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

staff at same site and datum used April 17 to June 26,1914. Mrs. John B. Curtis, 

observer.

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

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

about 100 feet below gage, but this dam was torn out August 17-19 and stage- 

- discharge relation entirely changed. New control is of rocks and gravel; somewhat shifting. One channel at all stages, but banks are very brushy and stagedischarge relation may be affected.

EXTREMES OP DISCHARGE. Maximum stage recorded during yerr, 2.94 feet at 

3 p. m. May 26 (discharge, 50 second-feet); minimum stage recorded, 1.36 feet at 

2 p. m. September 1 (discharge, 2.2 second-feet).

1914-15: Maximum stage recorded, 4.39 feet April 17, 1914 (discharge, 281 

second-feet); minimum stage recorded September 1, 1915.

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

DIVERSIONS. No known diversions above gage.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Two rating cv*ves used, each 

fairly well defined, one applicable October 2 to November 20 and April 25 to 

August 16, the other August 20 to September 30. Records lacHng for several 

short periods, owing to unsatisfactory operation of water-stage recorder. Mean 

daily gage heights obtained by inspecting recorder graph. Daily discharge ascertained by applying gage heights to rating tables. Records good for June and 

July and fair for other months.

64 SURFACE WATEE SUPPLY, 1915, PART XII B.

IDAHO (GOVERNMENT) CANAL NEAR FIRTH, IDAHO.

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

metal flume by which canal crosses the Eastern Idaho Slough, one-fourth mile 

below nearest highway bridge, 1J miles below the point where Sard Creek crosses 

the canal, 5 miles southeast of Firth, and about 5 miles above po;nt where canal 

discharges into Blackfoot River.

RECORDS AVAILABLE. March 29, 1914, to September 30, 1915.

GAGE. Friez water-stage recorder on left bank, inspected by J. A. Vaugho.

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

above station.

CHANNEL AND CONTROL. Bed of canal composed of silt, sand, and fire gravel; probably shifts slightly; flume heading just below gage furnishes wl it should be a 

permanent control for high stages. Point of zero flow about gage height 0.6 foot.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 4.20 feet at 6 p. m 

May 12 (discharge, 288 second-feet); minimum discharge practically zero,but can 

not be exactly determined as water was below inlet pipe to float well.

1914-15: Maximum stage recorded, 4.29 feet at 5 a. m., May 9, 1914 (discharge, 

315 second-feet); minimum practically zero, as stated in preceding paragraph.

WINTER FLOW. Stage-discharge relation seriously affected by ice. Data insufficient 

to warrant determinations.

DIVERSIONS. None above station or between station and outlet of crjaal into Blackfoot River.

REGULATION. Flow regulated partly by Snake River head gates, 12 miles above station, and partly by gates at the Sand Creek crossing, about 1J mil^s above.

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

December 9 to about March 13. Rating curve well defined above 40 second-feet. 

Recorder not operated during winter; outside staff gage read weekly December 9 

to March 13. Mean daily gage heights obtained by inspecting recorder graph. 

Daily discharge ascertained by applying gage heights to rating table. Records 

of flow exceeding 40 second-feet excellent; for lower flow records are less reliable 

because of poorer definition of rating curve and possible shifting o* canal bed.

Idaho (Government) canal diverts water from left bank of Snake F;ver in sec. 31, 

T. 1 N., R. 37 E., and discharges into Blackfoot River in sec. 24, T. 2 S., R. 36 E. 

The canal receives water from Sand Creek about 1J miles above this station. Water 

discharged into Blackfoot River during the irrigation season is diverged by the Fort 

Hall upper and lower canals for use on Fort Hall reservation. For record at station 

at head of canal see page 51.

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 head gates half a mile above crosses canal and about 2$ miles southeast 

of Blackfoot.

RECORDS AVAILABLE. May 15, 1912, to September 30, 1915.

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

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

at same site but at datum 1.53 feet lower than that of staff gage was used from 

1912 to 1914.

DISCHABGE MEASUREMENTS. Made from suspension footbridge at gage.

CHANNEL AND CONTROL. Channel at gage is trapezoidal concrete rating station at 

sides of which mud and silt have been deposited. Principal control is a wooden 

check across the canal about a third of a mile below gage; this control r?jnamed 

»unchanged from April 20 to September 30, 1915, but variations in the anount of 

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

the growth of moss and weeds in the canal caused several changes in the stagedischarge relation during the season.

EXTREMES OP DISCHARGE. 1912-1915; maximum stage recorded, 1.70 feet July 14, 

1915 (discharge, 156 second-feet), corresponding to about 3.23 feet on eld gage; 

canal reported dry on many dates.

WINTER PLOW. No winter records obtained. Small -quantities of water ar? run at 

times for use of stock but during most of the winter the head gates are clo^d.

DIVERSIONS. None above gage; a large lateral diverts water about a quarter of a mile 

below gage, and one small ditch diverts between the gage and the ch%k that 

acts as the main control.

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

ACCURACY. Stage-discharge relation not permanent; affected by variation in quantity of water diverted by large lateral below gage and by growth of moss at d weeds 

in canal. Rating curves fairly well defined; applicable as follows: October 

1-10; April 20-30; and August 3 to September 30; May 23 to July U. Gage 

read to tenths or half tenths twice daily. Daily discharge ascertained by 

applying daily gage heights ti rating tables; shifting-control method u^ed May 

1-22 and July 12 to August 2. Records fair.

Fort Hall lower canal diverts from left bank of Blackfoot River in sec. 11, T. 3 S., 

R. 35 E. Water is used for irrigation on Fort HaU Indian reservation.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 1.65 feet October 

21 to 25 (discharge, 308 second-feet); minimum stage recorded, 1.24 feet February 21 to March 15 (discharge, 196 second-feet).

1903-1915: Maximum stage recorded, 5.4 feet, at 9.30 a. m., Ju^e 4, 1914 (discharge, 1,880 second-feet); minimum stage recorded, 0.36 foot March 26-28, 1914 

(discharge, 41 second-feet).

WINTER PLOW. Stage-discharge relation unaffected by ice; open-chmnel rating assumed applicable.

DIVERSIONS. Numerous diversions are made from the river above tie gage. Sharp 

ditch and Streeter ditch divert water between the gage and the dam.

REGULATION. None, though the flow past the gage may be regulated by the gates 

at the Mackay dam when that structure is completed.

ACCURACY. Eating curve well defined below 1,000 second-feet but not verified by 

discharge measurements since July 28, 1914. Gage read to half-tenths once daily. 

Records fair.

SHARP DITCH NEAR MACKAY, IDAHO.

LOCATION. In sec. 12, T. 27 N., R. 23 E., 250 feet below head of ditch, half a mile 

below the Mackay dam, and 3J miles northwest of Mackay, Ouster County.

RECORDS AVAILABLE. June 6, 1912, to October 24, 1914, when station wa« discontinued.

GAGE. Vertical staff on left bank; installed June 26, 1913; read by F. Fclntosh. 

Original gage was vertical staff attached to inside of rating flume, on left side, 40 

feet below head gates and 200 feet above site of present gage. Relation between 

present and original gage not determined.

DISCHARGE MEASUREMENTS. Made by wading or from footbridge 100 feet below 

gage.

CHANNEL AND CONTROL. Control consists of gravel and sand and is poorly defined. 

Stage-discharge relation affected at times by backwater from moss and weeds in 

channel.

EXTREMES OP DISCHARGE. Maximum stage recorded during October, 6.55 feet 

October 1-2, 12, and 14 (discharge, 9.5 second-feet); minimum stage recorded, 

6.3 feet October 7 and 8 (discharge, 5.3 second-feet).

1912-1914: Maximum discharge recorded, 38 second-feet June 24, 1912 (corresponding to 6.9 feet on original gage); minimum discharge recorded, 1 secondfoot June 10,1913 (corresponding to 5.2 feet on original gage); accuracy of recorded 

minimum doubtful on account of unstable condition of gage. Ditch reported 

practically dry May 1-7, 1913.

WINTER FLOW. Presumably derived from leakage through head gates; ro winter 

records.

DIVERSIONS. Station is above all points of diversion for irrigation, but there is a small 

wasteway above the present gage.

REGULATION. Flow controlled by head gates and by small wasteway above gage.

ACCURACY. Records poor; applicability of rating curve not closely definei by discharge measurements.

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

E., a mile above heading of Streeter ditch and half a mile below Mackay drm. The 

water is used for irrigation, on land northwest of Mackay and above Streeter ditch.

PORTNETTF RIVER BELOW RESERVOIR, NEAR CHESTERFIELD, IDAHO.

LOCATION. In sec. 30, T. 6 S., R. 39 E., one-fourth mile below dam of Fortneuf-Marsh

Valley Canal Co., and 2$ miles west of Chesterfield, Bannock County. Topons

Creek enters Portneuf River 3 miles below. 

DRAINAGE AEEA. Not measured.

RECORDS AVAILABLE. May 23,1912, to April 9, 1915, when station was discontinued. 

GAGE. Vertical staff on right bank, directly under the Hess-McGinnir flume, which

carries the Portneuf diversion canal across the river; read about once a week by

employees of the Portneuf-Marsh Valley Canal Co.
SNAKE RIVER BASIN. 75

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

CHANNEL AND CONTROL. Bed consists of fine gravel. Stage-discharge relation 

seriously affected by moss in channel during summer. A wooden control, effective at low stages only, was installed July 27, 1912, about 6 feet below gage; a 

natural control farther downstream becomes effective at medium and hi|rh stages.

EXTREMES OF DISCHARGE. Maximum stage recorded October to April, 2.50 feet 

February 6,13, and 20 and March 13 and20 (discharge, 7.1 second-feet); r^inimum 

stage recorded, 2.30 feet January 23 (discharge, 1.5 second-feet).

1912-1915: Maximum stage recorded, 4.80 feet April 19-22,1914 (discharge, 81 

second-feet); minimum stage recorded January 23, 1915.

WINTER FLOW. Stage-discharge relation not affected by ice, probably because of 

proximity of station to reservoir. Open-channel rating curves assumed applicable.

DIVERSIONS. The Portneuf diversion canal takes water from river just below reservoir, 

one-fourth mile above station; present capacity of reservoir about 28,000 acrefeet; supply from Portneuf River augmented by feeder canal from Topo^s Creek. 

Main canal diverts about 23 miles below station; numerous ranch diversions 

between dam and point of diversion of main canal.

REGULATION. Flow regulated by gates at dam and by diversion into Portneuf diversion canal.

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

curves used, one applicable October 1 to December 15, the other Decenrber 16 to 

April 9. Gage read once or twice a week. Discharge ascertained by applying 

daily gage heights to rating table and interpolating for days on which gage was 

not read. Records poor.

Daily discharge, in second-feet, of Portneuf River below reservoir, near 

Idaho, for the year ending Sept. 80,1915.

employees of the Portneuf-Marsh Valley Canal Co.

DISCHARGE MEASUREMENTS. Made from downstream side of highway bridge half a 

mile above gage.

CHANNEL AND CONTROL. Control is a loose rock riffle 500 feet below g*#e. Blasting 

operations in March, 1915, removed some of the rock .forming this control and 

changed stage-discharge relation.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 3.51} feet October 

1-3 (discharge, 276 second-feet); maximum discharge, 284 second-feet June 23 

and 25 (corresponding to a gage height of 2.92 feet). Minimum stage recorded 

1.98 feet August 27-29 and 31 (discharge, 127 second -feet).

1913-1915. Maximum stage recorded, 6.1 feet, April 3, 1913 (discharge, 902 

second feet); minimum stage recorded August 27-29 and 31, 1915.

DIVERSIONS. Numerous ranch diversions are made above the station. The storage 

reservoir of the Portneuf-Marsh Valley Canal Co. (present capacit7 about 28,000 

acre-feet) is near Chesterfield. \

REGULATION. Flow during irrigation season regulated to large ex*<mt from the 

Portneuf-Marsh Valley reservoir.

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

rating curves used, one applicable October 1-30 and the other June 8 to September 

30. No records obtained November 1 to June 7. Daily discharge ascertained 

by applying daily gage heights to rating tables. Records good.

TOPONS CREEK SEAR CHESTERFIELD, IDAHO.

LOCATION. In sec. 34, T. 6 S., E. 38 E., at the Butterfield ranch, half a r<ile below 

head of diversion canal into the Portneuf-Marsh Valley reservoir ani 7 miles 

west of Chesterfield, Bannock County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE; April 25, 1912, to November 6, 1914, when station was discontinued.

GAGE. Vertical staff on right bank, back of Butterfi eld's barn and about 100 yards 

downstream.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Bed rocky. Channel likely to be partly clogged at times 

by drift and fallen trees.

WINTER FLOW. Stage-discharge relation greatly affected by ice.

EXTREMES OF DISCHARGE. 1912-1915: Maximum stage recorded, 8.0 feet May 21, 

1912 (discharge, 355 second-feet); minimum discharge probably occur-ed during 

winter months.

DIVERSIONS AND STORAGE. A few small ditches take out above and below station, 

but the main diversion, at least in flood period, is into the Portneuf-Marsh Valley 

reservoir on Portneuf River by means of a feeder canal heading about half a mile 

above the gage. s

ACCURACY. Stage-discharge relation not permanent. No discharge mer^urements 

made after September 18, 1914. Rating curve poorly defined. Gage read twice 

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

« table and interpolating for days of missing gage heights. Records -poor.

Daily discharge, in second-feet, of Topons Creek near Chesterfield, Idaho, for the year

ending Sept. SO, 1915.

2 miles southwest of Bridge, Cassia County. Clear Creek entBrs Raft River 

below Bridge but surface flow from this stream seldom reaches t^e river.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 18, 1909, to March 22, 1915, wlnn station was 

discontinued

GAGE. Inclined staff on right bank; installed February 24, 1911; road by Andrew 

Olson. A supplementary gage is also installed about 1 mile southeast of the main 

gage in a slough which carries water at flood times unless dammed off. Prior to 

February 24, 1911, two different gages were used, at the Langford ranch, about 

If miles above site of present gage.

DISCHARGE MEASUREMENTS. Made by wading near the gage or front a bridge onefourth mile downstream, at Olson's house.

CHANNEL AND CONTROL. Bed of stream is of clay overlain with gravel, and may be 

expected to shift during flood period. The high water channel is dammed off 

and carried no water during the year ending September 30, 1915.

EXTREMES OF DISCHARGE. Maximum stage recorded during open v^ter periods 

October to March 3.55 feet November 30 and December 5 and 7 (discharge, 

21 s»cond-feet); minimum stage recorded, 3.25 feet March 21 and 22 (discharge, 

10 second-feet).

1909-1915: Maximum stage recorded, 6.5 feet June 12, 1912 (discharge, 457

REGULATION. None except such as might be caused by changes of head gates of 

ditches and canals.

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

well defined. Operation of water-stage recorder not satisfactory and ga^e-height 

record unreliable at times. Mean daily gage heights obtained by inspecting 

recorder graph. Daily discharge ascertained by applying mean dfily gage 

heights to rating table. Records for greater part of year fair, but at times are 

poor, chiefly because of unreliability of gage-height record.

GAGE. Friez water-stage recorder on left bank since April 8, 1913. From May 1, 

1911, to August 27, 1912, a Lietz water-stage recorder was used, half a mile downstream from site of present gage and at different datum; from' August 28, 1912, 

to April 7, 1913, fragmentary records were obtained from a staff gage opposite 

Shaw's house, 1£ miles below site of present gage.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Stream bed composed of small boulders ani coarse gravel; 

fairly permanent except at extremely high stages. Banks brushy and not likely 

to be overflowed.

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

2.59 feet at 7 a. m. June 1 (discharge, 35 second-feet); minimum stage recorded, 

1.96 feet September 3-8, inclusive (discharge, 9.1 second-feet).

1911-1915: Maximum stage recorded, 3.17 feet at 10 p. m. February 28, 1914 

(discharge, 70 second-feet); minimum flow undoubtedly occurred in the winter, 

when stage-discharge relation is affected by ice.

WINTER FLOW, Stage-discharge relation greatly affected by ice; observations discontinued during the winter.

DIVERSIONS. None of consequence above station.

REGULATION. None.

ACCURACY. Stage-discharge relation practically permanent. Rafr'ng curve well 

defined. Gage-height record not fully reliable at times. Mean daily gage 

heights obtained by inspecting recorder graph. Daily discharge ascertained by 

applying mean gage heights to rating table. Records good.

BIRCH CREEK NEAR OAKLEY, IDAHO.

LOCATION. In.sec. 24, T. 14 S., R. 23 B., Cassia County, 600 feet below head gates of 

Birch Creek feeder canal, three-fourths mile below Martindale's house, and 5 

miles southeast of Oakley.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 21, 1914, to September 30, 1915, for present location; 

January 1, 1912, to May 31, 1913, for station above feeder canal.

GAGE. Friez water-stage recorder on left bank about 50 feet from the road; at station 

"above the canal a vertical staff gage was used, supplemented at times by a Lietz 

water-stage recorder.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Bed composed of boulders which contract the channel 

just below the gage and make a good control; permanent under ordinary conditions of flow. Banks high; overflow unlikely. Point of zero flow, according 

to measurements made May 6,1915, gage height 0.08 foot.

EXTREMES of DISCHARGE. Maximum stage during year, from wate~-stage recorder, 

1.24 feet at 7 p. m. April 16 (discharge, 20 second-feet); gage heights for period of 

minimum flow not available.

1912-1915: Maximum stage recorded, 4.5 feet April 8, 1912 (discharge, 55 

second-feet); minimum stage recorded, 0.12 foot at 9 p. m. August 26, 1914 

(discharge practically zero).

WINTER PLOW. Observations discontinued during winter.

DIVERSIONS. The Birch Creek feeder canal diverts water from tl ^ stream about 

600 feet above the gage and discharges into the Goose Creek reservoir of the 

Twin Falls-Oakley Land & Water Co. Practically no water was diverted through 

this canal during 1915.

REGULATION. The flow can be entirely or partly regulated at the h^ad gates of the 

feeder canal.

ACCURACY. Stage-discharge relation practically permanent. Ratir<r curve poorly 

defined October 1 to December 6, fairly well defined March to July. Mean 

daily gage heights obtained by inspecting recorder graph. Daily discharge 

ascertained by applying mean gage heights to rating tables. Records fair.

NORTH SIDE TWIN FALLS CANAL AT MILNER, IDAH*\

LOCATION. In sec. 20, T. 10 S., R. 21 E., Minidoka County, at high-ray bridge half a 

mile north of Milner post office and about three-fourths mile bebw head gates at 

Milner dam.

RECORDS AVAILABLE. May 10, 1909, to September 30, 1915.

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

by F. W. Deming, October 1, 1914, to June 26, 1915, and by T. R. Newell, June 

27, to September 30, 1915. Datum of gage has remained unchanged since the 

establishment of the station and the original gage is still in use. A slide gage was 

installed on the bridge in 1911 and was set to read the same as fie vertical staff, 

but its use was discontinued in 1913. A Lietz water-stage recorder was installed 

in 1912, in a shelter over the staff gage, but it never operated enti^ly satisfactorily 

and its use was abandoned in 1913. At the present time the vertical staff is used 

exclusively.

DISCHARGE MEASUREMENTS. Made from a cable about 150 feet below the gage.

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

growth is heavy during the summer months and stage-discharge relation is greatly 

affected. Control section apparently indeterminate.

WINTER PLOW. Stage-discharge relation not affected by ice; open-channel rating 

curves used throughout year.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.6 feet at 8 a. m. 

June 14 (discharge, 2,600 second-feet); canal reported dry October 7 to November 25.

1909-1915: Maximum discharge recorded, 2,800 second-feet, July 13, 14, 19, 

and 20, 1913, corresponding to a gage height of 7.9 feet. Canal reported dry at 

various times in 1909, 1910, and 1914.

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

gage. Surplus water may be discharged into the river through vuste gates about 

200 feet below head of canal.

REGULATION. Flow regulated by the head gates and waste gates.

ACCURACY. Stage-discharge relation riot permanent. Gage read on-?e daily October 

1 to June 26 and twice daily June 27 to September 30. Daily discharge ascertained by shifting-control method. Records excellent for periods in which discharge measurements were made daily; good for rest of year. i

COOPERATION. Most of the discharge measurements have been, made by the hydrographer stationed at this point by the State during the irrigation season in connection with the delivery of stored water from Jackson Lake.

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

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

240,000 acres of land in Minidoka, Lincoln, and Gooding counties. The distribution 

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

SNAKE RTVEB BASIN. 93

SOUTH SIDE TWIN FALLS CANAL AT MILNER, IDAHO.

LOCATION. In sec. 29, T. 10 S., R. 21 E., at the wagon bridge about one-ei?hth of a 

mile below the head gates at the village of Milner, Twin Falls County.

RECORDS AVAILABLE. May 10, 1909, to September 30, 1915.

GAGE. Vertical staff in two sections, read by F. W. Deming October 1, 1914, to 

June 26, 1915, and by T. R. Newell from June 27 to September 30, 1915. 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 low-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 ether. A 

Friez water-stage recorder is installed opposite the upper staff gage, but was not 

in use during the year ending September 30, 1915.

DISCHARGE MEASUREMENTS. Made from the bridge.

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

permanent, but slight changes of control occasionally occur due to washing in 

and deposit of silt.

WINTER PLOW. Stage-discharge relation seldom affected by ice; open-chanr si rating 

curves used throughout year. Because of the close proximity of tin gaging 

station to the head gates, ice never forms in the immediate vicinity of the gage, 

but it has been known to form to a sufficient extent farther down the canal to affect 

the stage-discharge relation.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 9.8 feet May 1-9, 

June 12-14 and 17 (discharge, 3,250 second-feet); minimum stage reccrded, 1.8 

feet March 10 and April 3 (discharge, 94 second-feet).'

1909-1915: Maximum stage recorded in May and June, 1915; mininmm stage 

recorded, 0.8 foot April 7, 1913 (discharge, 11 second-feet).

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

below.

REGULATION. Flow regulated at head gates.

ACCURACT. Stage-discharge relation practically permanent, but may hrve been 

changed slightly by effect of ice during winter months. Rating curve well defined. 

Gage read once daily October 1 to June 26 and twice daily June 27 to September 

30. Discharge determined by applying mean daily gage height to rating table. 

Open-water records good; winter records somewhat uncertain, owing to unknown 

effect of ice.

COOPERATION. Gage-height record furnished and part of the discharge measurements made by employees of the Twin Falls Canal Co. and of the Idrho State 

Engineer.

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 the irrigation of 

about 200,000 acres of land in the vicinity of Twin Falls. The distribution system 

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

BIG COTTONWOOD CREEK NEAR OAKLEY, IDAHO.

LOCATION. In sec. 19, T. 13 S., R. 21 E., one-fourth mile above hiding of Twin 

Falls-Oakley Land & Water Co. feeder canal, 1 mile above J. H. Boark's house, 

2 miles above mouth of Cedar Creek, and 10 miles northwest of Oakley, Cassia 

County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. November 27, 1909, to January 10, 1915, wl ^n station was 

discontinued.
SNAKE RIVER BASIN. 95

GAGE. Friez water-stage recorder on left bank half a mile above site of vertical 

staff gage which was used November 27, 1909, to April 27, 1913. Present gage 

read 0.72 foot July 28, 1913, when old gage read 1.20 feet.

DISCHARGE MEASUREMENTS. Made, by wading or from footbridge at old statfon.

CHANNEL AND CONTROL. Bed composed chiefly of small cobblestones and loulders; 

may shift at high stages. Banks fairly high; overflow unlikely. Point of zero 

flow estimated August 25, 1915, gage height 0.3 foot.

EXTREMES OF DISCHARGE. Gage heights for the year ending September 30, 1915, too 

incomplete to warrant publication of maximum and minimum.

1909-1914: Maximum stage recorded, 3.7 feet (old gage datum) May 30, 1912 

(discharge, 125 second-feet); minimum discharge practically zero and was 

observed in both 1910 and 1915.

WINTER PLOW. Stage-discharge relation not seriously affected by ice; open-channel 

rating curve assumed applicable.

DIVERSIONS. During the late summer most of the flow of the stream is diverted 

around the station in order to minimize loss by seepage. The capacity of the 

diversion ditch is not definitely known.

REGULATION. None except that due to diversion.

ACCURACY. Stage-discharge relation practically permanent throughout the year. 

Eating curve fairly well defined. Gage-height record fragmentary. Mean daily 

gage heights determined by inspecting recorder graph. Daily discharge ascertained by applying mean gage heights to rating table. Records fair atove and 

poor below 2 second-feet.

COOPERATION. Gage-height record furnished by the Twin Falls-Oakley Land & 

Water Co.

RECORDS AVAILABLE. September 17, 1909, to September 30, 1915.

GAGE. Barrett and Lawrence water-stage recorder on the right bank; installed 

November 20, 1911. Gage used prior to June 30, 1910, was a vertical staff on 

right bank a short distance upstream from site of present gage r ud at different 

datum. From July 1, 1910, to November 19, 1911, record was obtained from a 

Friez recorder at present site and datum.

DISCHARGE MEASUREMENTS. Made by wading or from a cable 20 fee* below gage.

CHANNEL AND CONTROL. Bed composed of gravel. Control shifts slightly. At high 

stages left bank is subject to overfldw, and creek may flow in two channels.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.79 feet May 25 

and'26 (discharge, 246 second-feet); minimum stage recorded, 2.18 feet September 14 and 16 (discharge, 14 second-feet).

1909-1915: Maximum stage recorded, 7.5 feet May 22, 1912 (discharge, 1,280 

second-feet); minimum stage recorded 2.18 feet September 14 and 16, 1915 (discharge, 14 second-feet).

WINTER FLOW. Stage-discharge relation not seriously affected by ice; open channel 

rating curve assumed applicable.

DIVERSIONS. A large number of diversions on the ranches of the Vineyard Land & 

Stock Co. above the station appropriate practically all the lo^-water flow of 

Salmon Falls Creek and Shoshone Creek.

REGTOATION. None above the gage. The dam of the Twi,n Falls-Salmon River Land 

& Water Co. is about 15 miles below the station and the Salmon reservoir has a 

capacity of about 180,000 acre-feet.

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

denned October 1 to December 15 and December 30 to September 30. Mean 

daily gage heights obtained by inspecting recorder graph. Daily discharge 

ascertained by applying mean gage heights to rating tables; shifting-control 

method used December 16-29. Records good.

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

made by the Twin Falls-Salmon River Land & Water Co.

San 'Jacinto, Elko County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 14, 1914, to August 24, 1915, when action was discontinued.

GAGE. Stevens water-stage recorder on right bank; installed August 27,1914; May 14 

to August 27, staff gage about 500 feet downstream at different datum, used also 

as a reference gage for Lietz water-stage recorder June 15 to July 31, 1914, and 

Stevens recorder August 3 to 27, 1914.

DISCHARGE MEASUREMENTS. Made by wading or from a cable abo^t 500 feet downstream.

CHANNEL AND CONTROL. Bed consists of gravel and loose rocks. Control not 

permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.94 feet 9 to 11 

p. m. May 23 (discharge, 151 second-feet); Tpinimi^Tn stage, 3.5S feet at 10 a. m. 

July 27 (discharge, 7.6 second-feet).

1914-15: Maximum stage recorded, 5.94 feet 9 to 11 p. m. May 23, 1915 (discharge, 151 second-feet); minimum stage, 0.26 foot (old staff gag-e datum) August 

22-27, 1914 (discharge, 7.4 second-feet).

WINTER FLOW. Stage-discharge relation probably affected by ice. No winter records 

obtained.

DIVERSIONS. Station above all diversions -on Shoshone ranch. Numerous diversions 

made in Shoshone basin about 10 miles above station.

ACCURACY. Stage-discharge relation not permanent; changed daring the winter. 

Rating curves well defined October 1 to December 6 and February 15 to August 24.

SNAKE EIVEE BASIN. 103

BIO WOOD RIVER AT HAILEY, IDAHO.

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

southwest of Hailey, Blaine County.

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

RECORDS AVAILABLE. June 11 to September 30,1915.

GAGE. Inverted stadia board spiked to pile near left abutment of bridge" read by 

G. C. Hendrickson.

DISCHARGE MEASUREMENTS. -Made from bridge or by wading.

CHANNEL AND CONTROL. Channel fairly straight above and below station. Banks 

low, covered with light brush, and subject to overflow at high stages, irhen river 

may flow in from one to three channels, the number depending on the stage. 

Bed consists of coarse gravel and sand; clean. Low-water control consists of 

sheet piling used to protect a water main crossing river; high-water control subject 

to shift but permanent during 1915. Point of zero flow, determined August 5, 

1915, gage height 5.7 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.23 fee* June 25 

(discharge, 883 second-feet); minimum stage recorded, 4.88 feet September 

29-30 (discharge, 21 second-feet).

WINTER FLOW. No information.

DIVERSIONS. Only a few small diversions for irrigation are made above tl * station. 

The Hailey power plant, half a mile upstream, utilizes as a tailrace a natural 

channel on the east side of the river known as Big Wood Slough; a larps amount 

of water diverted from main channel in this manner is returned to river below 

station. A record of the flow of Big Wood Slough is obtained, and the total flow 

of Big Wood River is represented by the amount of water passing botl stations.

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

some diurnal fluctuation in flow passing the gage. Observations on the river 

and on Big Wood Slough are taken practically at the same hour each dsy, so that, 

the effect of regulation is probably eliminated.

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

defined for low and medium stages. Gage read to hundredths dail;'. Daily 

discharge ascertained by applying gage heights to rating table. Records good.

COOPERATION. Gage-height record furnished and most of the-discharge measurements 

. made by the Idaho Irrigation Co.

For record of Big Wood Slough see page 110.

GAGE. Vertical staff on left bank.

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

CHANNEL AND CONTROL. Channel is cut in lava rock. Stream bed rough. Control

somewhat shifting. On account of rough cross section and irrofijulai' velocities

conditions for making measurements are poor. 

EXTREMES oi1 DISCHARGE. Maximum stage recorded during the year, 9.4 feet at

7 p. m. July 11 (discharge, 242 second-feet); minimum stage recorded, 7.48 feet

September 25 and 27 (discharge, 22 second-feet). 

1911-1915: Maximum stage recorded, 15.0 feet May 18, 1911 (discharge, 3,180

second-feet); minimum stage recorded 1.22 feet February 14, 1911 (discharge,

zero). Zero discharge also recorded February 9-13 and March 5-6, 1911, and

October 19-20 and 26, 1912.

WINTER FLOW. Observations discontinued during the winter. 

DIVERSIONS. Station is below all diversions of the Idaho Irrigation Co. The North

Gooding and Rich-field canals divert between the station and the Magic dam. 

REGULATION. Flow past station is regulated by gates at Magic dam and by the head

gates of the North Gooding and Richfield canals.

BIG WOOD SLOUGH AT HAILEY, IDAHO.

LOCATION. In Bee. 9, T. 2 N., R. 18 E., at highway bridge about o^e-eighth mile 

northeast of the Bteel highway bridge across Big Wood River and one-eighth 

mile southwest of Hailey, Blaine County.

RECORDS AVAILABLE. June 11 to September 30, 1915.

GAGE. Inverted stadia board spiked to center pile on downstream sMe of highway 

bridge; read by G. C. Hendrickson.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel. Bank^ covered with 

brush and subject to overflow. One channel at all stages. Control consists of 

top of a wood-stave water pipe laid in bed of stream about 15 feet below gage.

EXTREMES OP DISCHARGE. Ma-rimnm stage recorded during year, 1.64 feet July 9 

(discharge, 207 second-feet); minimum stage recorded, 2.03 feet August 27 (discharge, 117 second-feet).

WINTER FLOW. No information.

DIVERSIONS. None.

REGULATION. Amount of water passing gage affected by load at power plant half a 

mile upstream and there is considerable diurnal fluctuation. River is affected 

inversely by any such regulation, so that the accuracy of the surrmation of the 

two records is presumably affected only slightly by this factor.

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

defined. Gage read to hundredths once daily. Daily discharge ascertained' by 

applying daily gage heights to rating table. Records good.

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

made by the Idaho Irrigation Co.

Big Wood Slough is a natural channel of Big Wood River that is utilised also as a 

tailrace for the Hailey power plant. The record at this station repre^nts a portion 

of the natural flow of Big Wood River and taken in conjunction with the record at 

the nearby station on the river will show the total flow of the river at tMs point. For 

record of station on the river see page 103.

DRAINAGE AREA . Not measured.

RECORDS AVAILABLE. July 3,1909, to March 15,1915, when station vas discontinued. 

GAGE. Vertical staff on right bank near Dunham's house; read I y Sid Dunham.

Original gage (in use July 3,1909, to March 1,1910, inclusive) w»«i a vertical staff

on the right bank a quarter of a mile upstream from site of preaent gage. Relation

between the two gages not determined.

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

CHANNEL AND CONTROL. Bed of stream and control composed of coarse gravel,

shifting during floods. One channel at all stages, although rigM bank may be

overflowed in times of flood; left bank rocky and high. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.21 feet May 1

(discharge, 607 second-feet); minimum stage recorded, 3.7 feet December 10-21

(discharge, 59 second-feet). 

1909-1915: Maximum stage recorded, 10.6 feet (on old gage) March 1, 1910

(discharge, 5,660 second-feet); minimum stage recorded, 3.20 feet January 10,

1913 (discharge, 2 second-feet). 

WINTER FLOW. Stage-discharge relation not affected by ice. Hot springs along the

river keep the temperature of the water above the freezing point. 

DIVERSIONS. A few small ditches serving ranches divert water fron the tributaries

of Bruneau River above the gage. 

REGULATION. None. 

ACCURACY. Stage-discharge relation practically permanent October to March.

Rating curve fairly well defined. Gage read to half tenths on~e daily. Daily

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

good.

The following discharge measurement was made by A. W. Harrington: 

May 1,1915: Gage height, 5.21 feet; discharge, 607 second-feet.

BRtTlTEAtr RIVER NEAR GRANDVIEW, IDAHO.

LOCATION. In sec. 1, T. 6 S., R. 4 E., 500 yards below the Grandview dair and the 

head of the Grandview canal, 1J miles above mouth of Bruneau River, and 11 

miles southeast of Grandview, Owyhee County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. January 1,1895, to December 31,1903; May 1,1909, to September 30, 1915.

GAGE. Vertical staff on left bank; installed March 10,1910; read by 8. A. Hullenix. 

Gages used prior to March 10,1910, differed slightly in location and were at a datum 

' 0.87 foot higher than that of present gage.

DBSCHAKSE MEASUREMENTS. Made by wading or from cable just above ga?e.

CHANNEL AND CONTROL. Bed and control consist of coarse gravel which shifts during 

extreme floods. Banks clean. One channel at all stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.2 feet at 11 a. m. 

May 22 (discharge, 1,210 second-feet); mjr>imtim stage recorded, 1.9 feet. July 31 

to August 8 (discharge, 5 second-feet).

1895-1903 and 1909-1915: Maximum stage recorded March 2, 1910, de*«rmined 

by observing position otflood marks, equal to 11.0 feet on present gage (discharge 

estimated from extension of rating curve, 5,700 second-feet); minimum stage 

recorded, 1.7 feet August 27 and September 3-7, 1911 (discharge, 1 second-foot).

WINTER FLOW. Stage-discharge relation not affected by ice, presumably I eeause of 

the numerous hot springs in the vicinity of Hot Spring aad Bruneau.
118 SURFACE WATER SUPPLY, 1915, PART XII B.

DIVERSIONS. Grand view canal and Buckaroo ditch are the principal diversions rfbove 

the station, but a number of small ditches also divert water from tl 3 Bruneau and 

its tributaries for use on ranches.

REGULATION. Practically no water is stored above the station. The Grandview 

dam, which is a diversion structure only, impounds in its reservoir a relatively 

small quantity of water.

ACCURACY. Stage-discharge relation practically permanent during the year. Bating 

curve well denned. Gage read to tenths once daily. Observations October to 

December not entirely reliable. Daily discharge ascertained by applying daily 

gage heights to rating table. Records poor October to December, good for rest of 

year.

DISCHARGE MEASUREMENTS. Made by wading or from cable 125 feet above gage. 

CHANNEL AND CONTROL. Bed consists of ledge rock and boulders filled in with sand

and gravel; should be fairly permanent. One channel at all stages. Banks

covered with brush; both subject to overflow. At low stages there is a riffle

between the gage and Jones Brook but at high stages the rapids below the brook

may become the control. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.77 feet at 11 p. m.

April 16 (discharge, 432 second-feet); minimum stage, 1.35 feet at 11 p. m. August

23 (discharge, 7.5 second-feet). 

1913-1915: Maximum stage recorded, 9.36 feet April 15, 1914 (discharge, 1,360

second-feet); minimum stage recorded August 23, 1915. 

WINTER FLOW. Discharge relation is affected by ice. No records obtained during

the winter of 1914-15.

DIVERSIONS. No important diversions above gage. 

REGULATION. None. 

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

defined. Mean daily gage heights obtained by inspecting recorde~ graph. Daily

discharge ascertained by applying mean gage heights to rating table. Records

good.

OWYHEE RIVER NEAR OWYHEE, OREG.

LOCATION. In sec. 2, T. 21 S., R. 46 E., at the county bridge If miles southwest of 

Owyhee, Malheur County, 3 miles above mouth of river and 10 miles southwest 

of Nyssa.

DRAINAGE AREA. About 11,100 square miles. Watershed not well denned on available maps.

RECORDS AVAILABLE. March 26, 1890, to October 3, 1896; August 27, 190P, to September 30, 1915.

GAGE. Chain gage on upstream side of highway bridge; read by Mrs. S. J. Watson.

DISCHABGE MEASUREMENTS. Made from the bridge or by wading.

CHANNEL AND CONTROL. Bed consists of gravel and'small rock; may shift during 

high stages. Stage of zero flow determined September 4, 1915, as 1.85 feet.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 6.5 feet March 31 

(discharge 4,420 second-feet); minimum stage recorded, 2.05 feet September 4-5 

(discharge, 6 second-feet).

1890-1896 and 1903-1915: Maximum stage recorded, 12.9 feet March 2, 1910 

(discharge, 23,200 second-feet); minimum stage recorded, 2.00 feet September 

13-27, 1914 (discharge, 1 second-foot).

WINTER FLOW. Stage-discharge relation often seriously affected by ice; flow estimated from discharge measurments, observer's notes, and weather records.

DIVERSIONS. The Owyhee canal, the principal diversion above the station, heads 

about 6 miles above the gage. This canal diverts practically all of the natural 

low-water flow of Owyhee River; maximum diversion about 250 second-feet.

REGULATION. Variation in the flow at the station may be caused by manipulation of 

the gates at the head of Owyhee canal.

ACCURACY. Stage-discharge relation not permanent; affected by ice December 12 to 

February 10. Rating curve poorly defined used October 1 to December 11; 

curve fairly well defined used February 11 to September 30. Gage reac1 to quarter-tenths once daily. Gage height record doubtful at times. Daily discharge 

ascertained by applying gage heights to rating table. Records fair.

26 (determined from water marks; no gage-height record; discharge, 168 secondfeet); minimum stage recorded, 0.3 foot February 14 and August 18-26 (discharge, 

1.5 second-feet). Flow was probably as low as 1 second-foot for a few days in 

December and January and possibly between August 27 and 31.

1913-1915: Maximum stage recorded, 2.17 feet (present datum) April 10, 1914 

(discharge, 244 second-feet). Minimum occurred in 1915.

WINTER FLOW. Stream freezes over; stage-discharge relation affected by ice. During 

the early spring there is considerable diurnal fluctuation. Determinations of 

discharge based on observer's notes, weather records and observation made 

during short periods in which there was practically no effect from ice.

DIVERSIONS. No important diversions above gage.

REGULATIONS. None.

ACCURACY .-HStage-discharge relation practically permanent; affected by ice November 

15 to February 1. Rating curve well defined. Gage read to half tenths once or 

twice daily before September 3 and to hundredths after that date. Daily discharge ascertained by applying mean daily gage heights to rating taWe. See 

footnote to table of daily discharge. Open-water records good; others fair.

LOCATION. -In sec. 9, T. 30 S., E. 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 ABBA. Not measured.

RECORDS AVAOABLB. April 28, 1911, to September 30, 1915.
SNAKE BIVEB BASIN.

GAGE. Inclined staff on right bank, one-eighth mile below upper end of the canyon; read by Marcos Renteria.

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

CHANNEL AND CONTROL. One channel. Control consists of lava rock; probably 

permanent. During the summer months growth of moss frequently affects the 

stage-discharge relation to a marked degree.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 6.6 feet at 9 a. m.,

May 20 (discharge, 655 second-feet); creek dry at gage August 17 to September 30.

1911-1915: Maximum stage recorded, 9.9 feet April 24, 1912 (discharge, 2,150

second-feet); creek reported dry for periods of several weeks in 1911, 1914, and

1915.

WINTER PLOW. Stage-discharge relation seriously affected by ice; flow estimated 

from observer's notes and weather records.

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

small diversions in the valley above the gage. Flood water ie also diverted into 

the Antelope reservoir.

REGULATION. None.

ACCURACY. Stage-discharge relation practically permanent; affected by ice November 19-24 and December 1 to February 28, and by growth of moss drring the 

summer. Rating curve well defined. Gage read to hundredths on^e daily. 

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

Records good except for periods during which Stage-discharge relation war affected 

by ice or moss.

OWTHEE CANAL NEAR OWYHEE, OREG.

LOCATION. In sec. 6, T. 2] S., R.' 46 E., at the bridge which crosses the canal at the 

Wilson ranch, 2$ miles below head of canal, 5 miles southwest of Owyhee, Malheur County, and 15 miles southwest of Nyssa.

RECORDS AVAILABLE. May to October, 1904; May to September, 1905; October 5, 

1911, to September 30, 1915.

GAGE. Inclined staff on right bank at upstream eide of bridge; read during the 

irrigation season by the ditch rider. Gage used during 1904 a,nd 1905, was omefourth mile upstream from site of present gage.

DISCHARGE MEASUREMENTS. Made from the bridge or by wading.

CHANNEL AND CONTROL. Bed of canal ie clean and smooth. Control not well denned 

but fairly permanent.

EXTREMES OP DISCHARGE. 1904-1905 and 1911-1915: Maximum rtage recorded, 5.2 

feet May 18 and 23,1915 (discharge 240 second-feet); no flow June 18-19, June 24, 

and July 10-11, 19] 5, and at various times in 1912, 1913, 1914, and 1915.

WINTER PLOW. Canal freezes. Winter gage readings not available; flW estimated 

from discharge measurements and observer's notes.

DIVERSIONS. Surplus water is returned to the Owyhee River thror^h'two wasteways 

between the gage and the station on the river near Owyhee; cne of these wasteways is a quarter of a mile below the gage. Two small ditchep with a combined 

, capacity probably not exceeding 3 second-feet divert from th1? canal above the 

station.

REGULATION. Abrupt changes of stage due to manipulation of he^-d gates not to be 

expected, as water is kept at nearly constant stage.

ACCURACY. Stage-discharge relation not changed during the yea*-; affected by ice 

during the winter. Rating curve well defined. Gage read to tenths once daily. 

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

Records good during irrigation season but poor for winter.

The Owyhee canal diverts water from Owyhee River in sec. 18, T. 21 S., R^ 

46 E., and in 1915 supplied water for irrigation to about 9,000 a^es of land in the 

vicinity of Owyhee, Nyssa, and Ontario. During the winter the flow past the 

gage is derived from snow and from leakage through the head ga+«s and is returned

BOISE RIVER AT BOWLING'S RANCH, NEAR ARROWROCK, IDAHO.

LOCATION. In sec. 15, T. 3 N., E. 4 E., at Bowling station on Boise and Arrowrock 

Eailroad, Elmore County, three-fourths mile above Moore Creek, 2 miles below 

Highland power dam, and 4 miles below Arrowrock.

DRAINAGE AREA. 2,230 square miles (measured on topographic maps).

EECORDS AVAILABLE. March 13, 1911, to September 30, 1915.

GAGE. Friez water-stage recorder on left bank; installed March 19, 1915, to replace 

an inclined staff set to same datum and at practically the same site.

DISCHARGE MEASUREMENTS. Made from cable 50 feet below gage.

CHANNEL AND CONTROL. Bed composed of gravel and boulders. On^ channel at all 

stages. Control subject to slight changes.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 4.85 feet at 8 a. m. 

April 20 (discharge, 3,340 second-feet); minimum stage recorded, 2.08 feet at 

6 p. m. May 13 (discharge, 307 second-feet.)

1911-1915: Maximum stage recorded 8.7 feet June 13, 1911 (d^charge, 15,100 

second-feet); minimum stage recorded May 13, 1915.

WINTER PLOW. Stage-discharge relation at times seriously affectei by ice; flow 

estimated from discharge measurements, observer's notes, and weather records,

DIVERSIONS. No diversions of importance above the station and none between it 

and next station below.

REGULATION. On and after February 21, 1915, flow was regulated at Arrowrock 

dam, 4 miles upstream. Storage capacity of Arrowrock reservoir is about 280,000 

acre-feet. Water is stored during the winter and spring and released during the 

irrigation season. 

ACCURACY. Stage-discharge relation changed slightly during the witter of 1914-15; 

affected by ice December 14 to February 18. Two well-definei rating curves 

used, one applicable October 1 to December 13, the other February 19 to September 30. Staff gage read daily throughout the year. Mean daily gage heights 

after March 19 obtained by inspecting recorder graph. Daily discharge ascertained by applying mean daily gage heights to rating table. Eecords excellent 

for open-water season, good for December aad February, and iai1 for January.

COOPERATION. A large number of current-meter measurements made by employees 

of the United States Reclamation Service and of the Idaho State engineer have 

been furnished to the Survey.

BOISE RIVER NEAR HIGHLAND, IDAHO.

LOCATION. In sec. 32, T. 3 N., R. 4 E., Ada County, one-fourth mile above Smythe's 

ranch, half a mile below Kirks, the nearest station on the Bcise & Arrowrock 

Railroad, 2 miles below Moore Creek, and about 3 miles southwest of the old 

Highland post office.

DRAINAGE AREA. 2,650 square miles (measured on topographic maps).

RECORDS AVAILABLE. December 15, 1894, to October 31, 1904, at the old station 

near Boise, 8 miles downstream; March 18, 1905, to August 24, 1915. at the station herein described; August 25 to September 30, 19,15, at an?w site, 1| miles 

upstream.

GAGE, Friez water-stage recorder installed on left bank March 21, 1915, and used 

until August 24. August 25 to September 30, 1915, vertical staff installed on 

left bank about 1J miles farther upstream and at a different datum. March 18 

to July 31,1905, a temporary gage on right bank below Smythe's house; August 1, 

1905, to November 21, 1909, sloping gage at different datum on right bank about 

one-fourth mile above Smythe's house; November 22, 1909, to March 20, 1915, 

vertical and inclined staffs on left bank about 50 feet farther upstream and reading the same at low stages as the one across the river at the sane datum but 50 

feet below the water-stage recorder. Edgar Kirk, observer.

DISCHARGE MEASUREMENTS. Made from a-cable about 50 feet above the Friez gage.

CHANNEL AND CONTROL. Bed of stream composed of sand, gravel, and boulders. Control shifts frequently, owing to deposition or washing out of tailings from placer 

mines above. One channel at all stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.54 feet at 3 

a. m. June 26; maximum discharge recorded during year, 3,650 second-feet at 

11 a. m. April 20, at gage height 7.16 feet. Minimum discharge 463 second-feet 

December 17 and 21 (gage height 3.2 and 3.3; ice present); minimum stage recorded, 3.01 feet at 9 a. m. February 28.

1905-1915: Maximum stage recorded, 13.7 feet April 15,1907 (discharge, 17,000 

second-feet); minimum stage recorded, 2.7 feet December 10 and 11, 1905 (discharge, 450 second-feet).

A maximum discharge of 40,100 second-feet occurred June 14,1896, at the old 

station near Boise.
SKAKE 137

WIN/PER FLOW. Stage-discharge relation at times seriously affected by ice; flow 

estimated from discharge measurements, observer's note^s, and weather records.

DIVERSIONS. No important diversions above the station. The New Yorlr canal of 

the Boise project, United States Reclamation Service, diverts abort 6 miles 

below and has a maximum capacity of about 2,500 second-feet. Be'ow this a 

number of smaller canals divert from the river, their total maximurr capacity 

amounting to about 2,500 second-feet.

REGCXATION. Plow since February 21, 1915, regulated at Arrowrock dari, about 6 

miles above.

ACCURACY, Stage-discharge relation not permanent, changes being well denned by 

numerous discharge measurements. Affected by ice December 15 to about 

February 10. Several well-defined rating curves used. Mean daily ga?e heights 

March 21 to August 24 obtained by inspecting recorder graph. Daily discharge 

ascertained by applying mean daily gage heights to rating tables or by shiftingcontrol method. Open-water records good; winter records fair.

COOPERATION. Numerous discharge measurements made by employees of the United 

States Reclamation Service and of the Idaho State engineer.

COTTONWOOD CREEK NEAR ARROWROCK, IDAHO.

LOCATION. In sec. 35, T. 4 N., R. 5 E., Boise County, 200 feet above the bridge where 

the Twin Springs-Arrowrock road crosses the creek and one-fourth mile north of 

the south boundary of the Boise National Forest; 1£ miles above moutl of creek 

and about 13 miles, by road, from Arrowrock.

DRAINAGE AjpA. 23 square miles (measured on topographic maps).

RECORDS AVAILABLE. March 7, 1914, to September 30, 1915.

GAGE. Vertical staff reading from 0.0 to 3.0 feet, spiked to a large cottoniyood tree 

on left bank, 15 feet from road; read by Mrs. Eldora Bedrock.

DISCHARGE MEASUREMENTS. Made by wading, usually at a section about 100 feet 

above the gage.

CHANNEL AND CONTROL. Bed consists of boulders and gravel with pockets of fine 

sand; rough. Control shifts during high stages. No weeds grow in channel, but 

backwater from drift on control may be expected at times. A reinforced1 concrete 

artificial control was completed about 15 feet below the gage October 24, 1915.

EXTREMES OP DISCHARGE. Maximum stage during year, 1.00 foot at 8 a, m. May 

19 (discharge, 29 second-feet); minimum stage, 0.03 foot August 12 to 15 (discharge, 0.4 second-foot).

1914-15: Maximum stage recorded, 1.95 feet at 6 p. m. April 15,1914 (discharge, 

108 second-feet); minimum stage recorded August 12-15, 1915.

WINTER FLOW. Observations discontinued December 13 to February 2f, Stagedischarge relation apparently not affected by ice during period of record.

DIVERSIONS. No known diversions above gage. One small ditch diverts water at 

brush dam 250 feet below gage.

REGULATION. None.

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

curves used during the year. Gage-height record inaccurate at times. Daily 

discharge ascertained by applying daily gage heights to rating table or by shiftingcontrol method. Records fair.

COOPERATION. Some discharge measurements were made by engineers of tl 9 United 

States Reclamation Service.

MOORE CREEK NEAR ARROWROOT IDAHO.

LOCATION. In sec. 21, T. 3 N., R. 4 E., Boise County, one-fourth nolle al ove highway bridge on Boise-Arrowrock road, half a mile above mouth, and about 5 miles 

southwest of Arrowrock.

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

RECORDS AVAILABLE. October 1, 1914, to September 30, 1915 (discharge measurements only).

GAGE. Graduations to feet and tenths chiseled on the face of a rock ledge on the left 

bank of the stream and marked with white paint.

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

one-fourth mile below.

CHANNEL AND CONTROL. Bed consists of boulders, cobbles and sand. Cortrol shifts 

frequently owing to deposition of sand in low stages and cutting out in high stages. 

Stream usually carries much sand and silt as a result of placer operatiors in Boise 

Basin. One channel at all stages.

WINTER FLOW. Stage-discharge relation ordinarily not seriously affectei by ice. 

Effect of ice presumably diminished by the proximity of a group of htt springs 

just above station.

DIVERSIONS. No important diversions above station.

REGULATION. None.

COOPERATION. Discharge measurements made'during year by employees of United 

States Reclamation Service.

staff. v

DISCHARGE MEASUREMENTS. Made from the highway bridge or by wfding.

CHANNEL AND CONTROL. Bed of stream and coDtrol consist of grave' and cobbles; 

shift in high water and as a result of ice jams. One channel at all stages.

EXTREMES OF DISCHARGE. Maximum discharge recorded October to January: 98 

second-feet October 4-12 (gage height 1.6 feet); minimum discharge presumably 

occurred during December, when stage-discharge relation was afferted by ice.

1909-1915: Maximum stage recorded, 11.6 feet, morning of Marcl 2, 1910, from 

high-water marks (discharge estimated from extension of rating cirve as 16,400 

second-feet); minimum discharge recorded, 2.6 secoad-feet July 2F to August 5, 

1914 (gage height, 0.7 foot).

WINTER FLOW. Stage-discharge relation seriously affected by ice; f ow estimated 

from discharge measurements, observer's notes, and comparison v'th records at 

other stations.

DIVERSIONS. Numerous ranch diversions are made from both South Fork and'Malheur River above station.

REGULATION. None.

ACCURACY. Records for October and November, fair; those for December and January poor.

Control fairly permanent; effect of moss and weeds slight.

EXTEEMES OP DISCHARGE. 1914-15: Maximum discharge recorded, 20 second-feet 

October 4 to 12 (corresponding to a gage height of 1.9 feet); minimum stage 

recorded, 1.65 feet at time of measurement August 27 (discharge, 7.8 secondfeet). Lower discharges, of which there is no record, probably occurred during 

th'e summer.

1910-1915: Maximum stage recorded, 6.1 feet April 25, 1912 (discharge, 1,990 

second-feet); minimum stage recorded, 1.00 foot July 30 to August 1, 1914. (discharge, zero); zero discharge also recorded July 18 to 20, 1913, ft gage height 

1.20 feet.

156 SUILPACE WATEE SUPPLY, 1915, PART XII B. 

NORTH FORK OF PAYETTE RIVER AT LARDO, IDA.HO.

LOCATION. In sec. 8, T. 18 N., R. 3 E., about one-fourth mile below Lardo, Boise 

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

lake and the gage.

DRAINAGE AREA. 131 square miles (measured on topographic an<? LandX)fficemaps).

RECORDS AVAILABLE. September 1,1908, to September 30,1915.

GAGE. Inclined staff on left bank installed July 25, 1911; read daily 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. Gage datum unchanged since October 14, 1908.

DISCHARGE MEASUREMENTS. Made by wading or from cable cue-half 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, 4.8 feet at 7.30 

a. m. May 23 (discharge, 1,300 second-feet); minimum stage recorded, 1.55 feet 

September 25 to 30 (discharge, 19 second-feet).

1908-1915: 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).

WINTER PLOW. Stage-discharge relation not 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 changed during April, 1915; not affected by 

ice. Two well-defined rating curves used, October 1 to April 3 and April 9 to 

September 30. Gage read to quarter-tenths once daily. Drily discharge ascertained by applying daily gage heights to rating table. Records excellent.

DIVERSIONS. Practically no diversions made above station.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during winter; affected by ice December 1 to March 24. Two fairly well defined rating curves used, one October 1 to 

November 30, the other March 25 to September 30. Gage r?ad to half-tenths 

once daily; gage heights somewhat uncertain during low stages Daily discharge 

ascertained by applying daily gage heights to rating tables, except during period 

for which stage-discharge relation was affected by ice. Records good April to 

July; fair for October, November., August, and September; poor for winter 

months.

COOPERATION. Gage-height record furnished by L. S. Kimball.

CRANE CREEK NEAR MIDVALE, IDAHO.

LOCATION. In sec. 19, T. 12 N., R. 2 W., 300 feet below dam of Crane Creek Irrigation Co., and 12 miles southeast pf Midvale, Washington County. No tributaries 

between dam and station; Last Chance Creek enters a short distance below.

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

RECORDS AVAILABLE. October 30, 1910, to September 30, 1915.

GAGE. Staff on right bank in three vertical sections and one inclined section; read 

by Gilbert Thornton, gate keeper at the dam.

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

CHANNEL AND CONTROL. Bed composed of lava rocks and coarse gravel; vory rough. 

Control practically permanent. Banks very brushy.

45725° 18 WSP 413 11
162 SURFACE WATER SUPPLY, 19J.5, PART XII B.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 4.9 feet May 19-29 

(discharge, 629 second-feet); gates at dam closed January 1 to April 17, and discharge during this'period assumed as zero.

1910-1915: Maximum stage recorded, 8.9 feet December 3, 1910 (discharge, 

4,240 second-feet). Zero flow reported at various times when gates at dam were 

closed.

WINTER PLOW. Stage-discharge relation not affected by ice; open water rating 

curve assumed applicable in December. The comparative freedom from ice at 

this station is probably due to the proximity of the station to the reservoir.

DIVERSIONS. No large diversions above the gage. Flood waters are impounded in 

the storage reservoir of the Crane Creek Irrigation Co. just above the gage. The 

record of flow at the station shows only the amount of water disci arged from the 

reservoir and does not necessarily represent the true flow of Crane Creek.

REGULATION. Flow completely regulated by gates at dam. Wher the gates are 

closed the flow has been considered as zero, but there may be som* slight seepage 

which is th7ts unaccounted for.

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

Bating curve fairly well defined. Gage read to tenths once daily. Gage height 

record fair. Daily discharge ascertained by applying daily gage heights to rating 

table. Records fair.

thereafter; gage reader, J. L. Hendricks.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Gravel with some rock at control; fairly permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 1.25 feet May 14 

(discharge, 28 second-feet); minimum stage recorded, 0.82 foot April 28 (discharge, 

12 second-feet), caused by diversion of water in Eldcrado ditch.

WINTER FLOW. Stream does not freeze as most of the low-water flow ames from 

springs.

DIVERSIONS. An old mining ditch, the Eldorado, diverts water from mc*«t of the 

tributaries of South Fork above the station. It carried water during tl 3 greater 

part of April over the Beam Creek divide into Willow Creek, where it was used 

for irrigation. The water was turned out May 1.

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

defined between 10 and 25 second-feet. Gage read about every other day during 

April, and weekly thereafter. Daily discharge ascertained by apply'ig daily 

gage heights to rating table. Records fair.

with sand and gravel-. Control shifts slightly.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 4.4 feet at 9 a. m. 

June 2 (discharge, 3,780 second-feet); minimum stage occurred during winter 

months (discharge not accurately known).

1912-1915: Maximum stage recorded, 8.3 feet June 1, 1913 (discharge, 12,800 

second-feet); a discharge of 12,900 second-feet corresponding tc a gage height 

of 8.2 feet occurred June 10, 1912. Minimum stage and discharge, not accurately 

known, occurred during winter months.

WINTER PLOW. Stage-discharge relation affected by ice December to January; 

discharge estimated from weather records and observer's notes.

DIVERSIONS. A small ditch diverts from left bank between bridge and gage but 

its total capacity is less than 1 per cent of low-water flow.

REGULATION. None.

ACCURACY. State-discharge relation practically permanent during th^ year; affected 

by ice December 4 to February 10. Bating curve fairly well defined. Gage 

read to half-tenths once daily. Daily discharge, except during- winter, ascertained by applying daily gage heights to rating table. Open-water records good; 

winter records poor.

The following discharge measurement was made by Martin and Stewart of the 

United States Forest Service: 

November 27,1914: Gage height, 2.44 feet; discharge, 1,260 eeeond-f?et.

Daily discharge, in second-feet, of Salmon River at Salmon, Idaho, for the yew ending Sept.

rating curve assumed applicable.

DIVERSIONS. An inconsiderable amount of water is used for irrigation above gaging 

station.

REGULATION. None.

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

days in December. Rating curve well defined above 3,000 second-fee*. Gage 

read to hundredths twice daily. Daily discharge ascertained by applying gage 

heights to rating table. Records excellent.

No discharge measurements were made during the year.

GRANDE RONDE RIVER AT HILGARD, OREO.

LOCATION. In the SW. J sec. 32, T. 2 S., R. 37 E., half a mile east of Hflgard, Union 

County, at the county highway bridge just below Five Points Creek, about 8 

miles above head of Grande Ronde Valley.

DRAINAGE ABBA. 660 square miles.

RECORDS AVAILABLE. November 6, 1903, to March 3, 1910; October 1, 1910, to 

September 30, 1915, when station was discontinued.

GAGE. Vertical staff nailed to right abutment of former bridge; used since January 

5,1912. Gage reader, J. W. Scott. Gage on pier of former bridge used November 

6, 1903, to March 4, 1910, when bridge and gage were washed away. Gage on 

left abutment of the same bridge used 1910 and 1911.

DISCHAKGE MEASUREMENTS. Made from downstream side of new steel bridge about 

20 feet below gage, or by wading.

CHANNEL AND CONTROL. Sand and gravel; fairly permanent. The use of tbe stream 

for log driving formerly affected the stage-discharge relation, especially for about 

two months in early summer; no logs have been driven since about 1910.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.05 feet April 13 

(discharge, 1,240 second-feet); minimum stage recorded, 0.50 foot Augrst 30-31 

(discharge, 15 second-feet).

'1903-1915: Maximum stage recorded, 8.0 feet March 17, 1908; maximum discharge, 4,610 second-feet (gage height, 7.5 feet) April 14, 1904. Minimum stage 

recorded, 2.20 feet June 25, 26, 30, July 1, 1905 (discharge, 3 second-feet), caused 

by holding back water in logging dams. Minimum stage recorded since 1909, 

when the splashing ceased, 0.68 foot September 22 and 23, 1913 (discharge, 14.8 

second-feet).

WINTER PLOW. Stage-discharge relation seriously affected by ice about two months 

(average) each winter; flow estimated from meter measurements, observer's 

notes, and studies of weather records.

REGULATION. Practically none at present.

ACCURACY. Stage-discharge relation practically permanent during the year; affected 

by ice from December 9 to February 13. Rating curve well denned. Daily 

discharge (except for winter) ascertained by applying daily gage heights to rating 

table. Open-water records good; winter records poor.

WALLOWA RIVER AT JOSEPH, OREG.

LOCATION. In sec. 5, T. 3 S., R. 45 E., about '300 feet below the regulating dam at 

the outlet of Wallowa Lake, and 50 feet above footbridge; half a mile above 

Joseph, Wallowa County, above the head gates of four irrigating di+ehes, the first 

taking out 125 feet below the gage.

DRAINAGE AREA. -52 square miles.

RECORDS AVAILABLE. November 12, 1903, to August 23, 1907; Jim* 14, 1908, to 

March 31, 1914; May 20 to September 25, 1915.

GAGE. Vertical staff bolted to a large boulder on right bank, used since July 12, 

1905. Read by J. W. Winston. Original gage, read Novembe- 12, 1903, to 

March 30, 1905, on lake. Temporary gage 100 feet below dam, March 31 to 

July 11, 1905.

DISCHARGE MEASUREMENTS. Made by wading at low water; formerly from footbridge.

CHANNEL AND CONTROL. Boulders; practically permanent; banks are seldom overflowed; current awift and velocities uneven across section.
SNAKE EIVEE BASIN. 183

EXTREMES OF DISCHARGES. Maximum stage recorded during year, 3.20 feet at 8 

a. m. June 23 (discharge, 560 second-feet); minimum stage recorded, 1.88 feet 

at time of measurement March 22 (discharge, 41.6 second-feet).

1904-1915: Maximum stage recorded, 3.60 feet June 12-13, 1912 (discharge, 850 

second-feet). This can not be corrected to natural flow. Minimum stage recorded, 1.8 feet September 27, 30, October 1,1906, February 17 to March 16, 1907 

(discharge from revised curve, 30 second-feet). This is probably tl ? natural 

flow.

WINTER FLOW. Discharge relation unaffected by ice on account of proxirrity to the 

lake outlet.

REGULATION. About 10,000 acre-feet of storage has been developed in Wallowa 

Lake; used since 1905, and monthly discharge corrected for storage sin?e 1912.

ACCURACY. Stage-discharge relation practically permanent. Rating cu~ve fairly 

well defined between 40 and 400 second-feet and poorly denned out^de these 

limits. Daily discharge ascertained by applying gage heights to rating table. 

Monthly mean discharge corrected for storage in Wallowa Lake before computing 

discharge in second-feet per square mile and run-off in depth in inches. Records 

good.

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

March 22, 1915: Gage height, 1.88 fyet; discharge, 41.6 second-feet.

Daily discharge, in second-feet, of Wallowa River at Joseph, Oreg., for the year ending

office of Marengo, 9 miles southwest of Pomeroy, in Columbia County, 17| miles 

north of Dayton, and 14 miles above Petaha Creek.

DRAINAGE ABBA. Not measured.

RECORDS AVAILABLE. August 31, 1913, to June 30, 1915, when station was discontinued.

GAGE. Vertical staff in two sections at highway bridge. Lower section on .pile 

3 feet from left abutment; upper section on left abutment; read by William 

Brockman.

DISCHARGE MEASUREMENTS. Made by wading near gage.

CHANNEL AND CONTROL. Bed of stream composed of gravel. Control formed by 

riffle 75 feet below gage; shifting at high water. Banks not subject to cverflow. 

Stage of zero flow, determined September 29, 1915, gage height 0.3 foot.

EXTREMES OF DISCHARGE. Maximum discharge during the period October 1, 1914, 

to June 30, 1915, estimated at 285 second-feet May 20 and 21, by hydrograph 

comparison with record of Tucannon River near Starbuck; minimum stage 

recorded, 1.20 feet at 7.30 a. m. December 24 (discharge, 25 second-fret).

1913-1915: Maximum stage recorded, 2.55 feet at 4.40 p. m. April 15, 3914 

(discharge, 370 second-feet); minimum stage recorded December 24, 1914.

WINTER PLOW. Stage-discharge relation affected by ice for short periods during 

severe winters.

DIVERSIONS. Several small diversions for irrigation above station.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent; affected by ice Decemler 19-23 

and 28, 1914. Rating curve, well defined below 200 second-feet, used August 

31, 1913, to April 15, 1914; rating curve well defined throughout used April 15, 

1914, to June 30, 1915. Gage read to half-tenths twice daily from August 3], 

1913, to July 25, 1914, and to hundredths twice daily from July 26, 1914, to June 

30, 1915. Observer's record doubtful March 17 to April 2 and May 19-21, 1916. 

Daily discharge ascertained by applying mean daily gage heights to ratin? tables, 

except for periods of doubtful gage readings and ice effect. Records good except 

for periods of estimated discharge. Determinations of discharge August 31,1913, 

to September 30, 1914, supersede those published in. Water-Supply Paper 393.

198 SURFACE WATER SUPPLY, 1915, PART XII F

TUCAHNON RIVER NEAR STARBUCK, WASH.

LOCATION. In sec. 23, T. 12 N., E. 38 E., half a mile below mouth of Petaha Creek,

and 6 miles east of Starbuck, Columbia County. 

DRAINAGE AREA. Not measured.

BECORDS AVAILABLE. November 8, 1914, to September 30, 1915. 

GAGE. Inclined staff in two sections on left bank, 1,000 feet above observer's house;

read by Wesley Martin.

DISCHARGE MEASUREMENTS. Made by wading or from a bridge 1 mile below gage. 

CHANNEL AND CONTROL. Channel straight for 100 feet above and l^low gage. Bed

composed of solid rock. Banks made up of light soil; wooded; left bank high;

right is overflowed at gage height 5.5 feet. Control is a vertical c""op of 2 feet over

solid rock, 100 feet below gage. Stage of zero flow, determined September 28,

1915, gage height 0.6 ±0.1 foot. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.2 feet on morning

of February 1 (discharge, 970 second-feet); minimum stage, 1.60 feet August 24-31

(discharge, 39 second-feet). 

WINTER FLOW. Stage-discharge relation seriously affected by ice; flow estimated from

discharge measurements, observer's notes, and weather records. 

DIVERSIONS. Many small irrigation ditches divert water above gage probably about

10 per cent of natural flow during July and August. A large part of the diverted

water returns to the river above the gage in the form of seepage. 

BEGULATION. None. 

ACCURACY. Stage-discharge relation not permanent; changed by construction of a

low wing dam during August, 1915, and affected by ice during December and

January. Two rating curves used, each well defined below 600 second-feet;

one applicable November 8 to July 31, the other August 16 to September 30.

Gage read to hundredths twice daily. Daily discharge ascertained by applying

gage heights to rating table; shifting-control method used August, 1-15. > Records

excellent except for December, January, and August, for which they are good.

202 SURFACE WATER SUPPLY, 1915, PAET XII P

PALOUSE RIVER NEAR WINONA, WASH.i

LOCATION. In se,c. 5, T. 16 N., R. 39 E., 200 feet below Rock Creek, 7 miles southwest of WinoBa, in "Whitman County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. December 16,1914, to September 30, 1915.

GAGE. Inclined and vertical staff on right bank, 200 feet below confluence with 

Rock Creek; read by Theo. McDougall.

DISCHARGE MEASUREMENTS. Made from cable 900 feet below gage or by wading.

CHANNEL AND CONTROL. Bed composed of gravel; probably shifting. Right bank 

high; left bank subject to overflow at high stages. Stage of zero flow, according 

to measurements made December 16, 1914, and September 18, 1915, 0.0±0.1 

foot.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.2 feet at 4.20 

p. m. February 3 (discharge, 2,800 second-feet); minimum stag^ recorded, 0.48 

foot at 2.30 p. m. September 27 (discharge, 9 second-feet).

WINTER FLOW. Stage-discharge relation seriously affected by ice; flow estimated 

from discharge measurements, observer's notes, and weather records.

DIVERSIONS. Several irrigation ditches divert water above gage. Though small 

individually, they probably aggregate a large proportion of the extreme low-water 

flow.

REGtrLATioN. None.

ACCURACY. Stage-discharge relation practically permanent during the year; affected 

by ice for a few days in December and January. Rating curve well defined 

below 3,100 second-feet. Gage read to hundredths once daily; corrections to be 

applied to observed gage heights somewhat uncertain; very lifct*** diurnal,fluctuation. Daily discharge ascertained by applying daily gag® height to rating table. 

Records good except for periods in which flow was leas than 190 second-feet or 

gage was not read for five or more day».

204 SURFACE WATER SUPPLY, 1915, PART XII I 

PALOTTSE RIVER AT HOOPEE, WASH.

LOCATION. In sec. 26, T. 15 N., R. 37 E~., 1 mile east of Hooper, Whitman County, 

and 2 miles above Cow Creek.

DRAINAGE AREA. 2,210 square miles.

RECORDS AVAILABLE. April 1, 1897, to December 31, 1899; April 1, 1900, to April 

20,1907; June 14, 1908, to July 31, 1912; March 7, 1913, to September 30, 1915

GAGE. Vertical and inclined staff in four sections, on right bank, 300 feet above and 

across the river from the Oregon-Washington Railroad & Navigation Co.'s water 

tank. Original gage (Apr. 1 to Aug. 31, 1897), a vertical staff 1 mile above site 

of present gage; since September 9,1897, several gages <d present site and datum. 

Gage read by Mis. L. 0. Huffman.

DISCHARGE MEASUREMENTS. Made by wading or from cable 200 fee* below highway 

bridge at Hooper.

CHANNEL AND CONTROL. Gage is in long, riffle-controlled pool. Stream bed composed of solid rock covered with loose boulders; shifts during flcpds. Left bank 

high; not subject to overflow; right bank low and covered with brush.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 6.7 feet at 3 p. m., 

May 21 (discharge, 2,580 second-feet); probably higher stage and discharge 

during night of February 3. (See Palouse River near Winom, Wash.) Minimum stage recorded, 0.54 foot September 10-11 (discharge, 6 second-feet).

1897-1915: Maximum stage recorded, 21.0 feet March 2,1910 (discharge, 27,800 

second-feet); minimum stage June 25, 1910 (entire flow diverted; no flow past 

gage part of day).

WINTER FLOW. Stage-discharge relation not seriously affected by ice; open-channel 

rating curve assumed applicable. '

DIVERSIONS. Several small irrigation ditches divert water above the gage, the largest 

being the Palouse Irrigation & Power Oo.'s canal, the maxiirum capacity of 

which is about 15 second-feet.

ACCURACY. Stage-discharge relation changed during high water of February, 1914. 

Rating curve used March 7, 1913, to February 26, 1914, well denned between 

150 and 10,000 second-feet; curve used February 27, 1914, to Sep*«mber 30, 1915, 

well defined between 20 and 10,000 second-feet. Gage read to hundredths once 

daily. Daily discharge ascertained by applying daily gage teights to rating 

tables. Records good except those for periods of low water.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 15,1903, to September 30,1905 (published as "Rock 

Creek near St. John, Wash,"); March 30, 1914, to September 30, 1915.

GAGE. Vertical staff on.county bridge 200 feet below outlet of Rock Lake; fastened 

to downstream caisson of second pier from left bank. Gage used from October 

15, 1903, to September 30, 1905, was a vertical rod fastened to fifth pile bent of 

southeast approch to highway bridge over the creek at outlet of lal <3; datum 

of this gage not the same as that of present gage. Gage read by Herbert Babcock.

DISCHARGE MEASUREMENTS. Made by wading or from county bridge at gawe.

CHANNEL AND CONTROL. Bed of stream composed of solid rock covered unth sharp 

volcanic d6bris; will not shift. Right bank high; left bank low and subject to 

overflow at gage height 5.0 feet, so that two channels are formed. Control for 

stages up to 2.00 feet is rock riffle 100 feet below gage; control for higher stages is 

an unfinished earth dam half a mile below; low-water control permanent; highwater control unstable. Stage of zero flow, according to measurements made 

October 29, 1914, 0.35±O.Q5 foo.t.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 4.3 feet at 4 p. m. 

February 12 (discharge, 393 second-feet); minimum stage recorded. 0.30 foot 

October 1-17 (discharge practically zero).

1903-1905, 1914-15: Maximum stage recorded, 15.60 feet Marcl 9, 1904 

(discharge, 1,980 second-feet); minimum stage recorded, 10.00 feet September 23 

to October 25, 1904, 9.76 feet September 24-30, 1905, 0.30 foot September 4-9, 

1914, 0.20 foot September 10-30,1914, and 0.30 foot October 1-17,1914 (discharge 

during these periods practically zero).

WINTER-FLOW. Stage-discharge relation not affected by ice. Ice formed in still 

water, but control remained open.

DIVERSIONS. None.

REGOTATION. The gates in the low dam at outlet of Rock Lake are seldom regulated.

1 For discharge of Bock Creek at mouth see p. 211.
208 SURFACE WATER SUPPLY, 1915, PART XII B

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

Rating curve poorly defined below 10 second-feet, fairly well defined between 

10 and 60 second-feet, and well defined between 60 and 300 second-feet. Gage 

read to hundredths once daily; gage-height record not very reliable April 29 to 

October 31, 1914, and August 22 to September 30, 1915. ' Daily discharge ascertained by applying daily gage heights to rating table. Records gcod for discharge 

above 30 second-feet, fair for discharge between 10 and 30 second-feet, and poor 

below 10 second-feet.

STREAM-GAGING STATIONS AND PUBLICATIONS 

RELATING TO WATER RESOURCES.

ESrTRODTTCTION.

Investigation of water resources by the United States Geological 

Survey has consisted in large part of measurements of the volume of 

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

it has comprised also investigation of such closely allied subjects as 

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

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

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

appeared in the bulletins, monographs, professional papers, and 

annual reports.

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

coincide with natural drainage features as indicated below:

Part I. North. Atlantic slope basins.

II. South Atlantic slope and eastern Gulf-of Mexico basins.

III. Ohio River basin.

IV. St. Lawrence River basin. 

. V. Upper Mississippi Eiver and Hudson Bay basins.

VI. Missouri River basin.

VII. Lower Mississippi River basin. 

VIII. Western Gulf of Mexico basins.

IX. Colorado River basin.

X. Great Basin.

XI. Pacific slope basins in California. 

XII. North. Pacific slope basins, in three volumes:

A, Pacific slope basins in Washington and upper Columbia Eiver basin.

B, Snake River basin.

C, Lower Columbia River basin aiid Pacific slope basins in Oegon.

HOW GOVERNMENT REPORTS MAY BE OBTAINED OR CONSULTED.

Water-supply papers and other publications of the United States 

Geological Survey containing data in regard to the water resources' 

of the United States may be obtained or consulted as indicated 

below.

1. Copies may be obtained free of charge by applying to the 

Director of the Geological Survey, Washington, D. C. Th"» edition 

printed for free distribution is, however, small and is soon exhausted.

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

1915. The data for any particular station will, as a rule, be found in 

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

1903 to 1915, are published in Water-Supply Papers 97, 124, 165, 

201, 241, 261, 281, 301, 321, 351, 381, and 401, which contain records 

for the New England streams from 1903 to 1915. Results of miscellaneous measurements are published by drainage basins.

In these papers and in the following lists the stations are arranged 

in downstream order. The main stem of any river is determined 

by measuring or estimating its drainage area that is, the herdwater 

stream having the largest drainage area is considered the continuation of the main stream, and local changes in name and lake surface 

are disregarded. All stations from the source to the mouth of the 

main stem of the river are presented first, and the tributaries in 

regular order from source to mouth follow, the streams in each 

tributary basiirbeing listed before those of the next basin below.

In exception to this rule the records for Mississippi River are 

given in four parts, as indicated on page in, and the records for large 

lakes are presented in order of the streams around the rim of the lake.

The largest rivers discharging into the Pacific Ocean in Oregon 

and Washington are Rogue, Umpqua, and Columbia rivers and 

streams that reach the ocean through Puget Sound. The principal 

tributaries' of the Columbia are Kootenai, Clark Fork, Spokane, 

Wenatchee, Yakima, Snake, Walla Walla, Umatilla, John Day, Deschutes, Klickitat, Willamette, and Lewis rivers. Nisqually, Puyallup, 

White, Snohomish, and Skagit rivers flow into Puget Sounc\ The 

streams of this division drain wholly or in part the States of Idaho, 

Montana, Nevada, Oregon, Utah, Washington, and Wyoming.

GEOLOGIC FOLIOS.

Under the plan adopted for the. preparation of a geologic map of the United States 

the entire area is divided into small quadrangles, bounded by certain meridians and 

parallels, and these quadrangles, which number several thousand, are separately 

surveyed and mapped.1 The unit of survey is also the unit of publicatim, and the 

maps and description of each quadrangle are issued in the form of a folio When all 

the folios ate completed they will constitute the Geologic Atlas of the Ui ^ted States,

A folio is designated by the name of the principal town or of a promirent natural 

feature within the quadrangle. Each folio includes maps showing the topography, 

geology, underground structure, and mineral deposits of the area mapped and several 

pages of descriptive text. The text explains the maps and describes the topographic 

and geologic features of the country and its mineral products. The topographic map 

shows roads, railroads, waterways, and, by contour lines, the shapes of the hills and 

valleys and the height above sea level of all points in the quadrangle. The arealgeology map shows the distribution of the various rocks at the surface. Th ?- structuralgeology map shows the. relations of the rocks to one another underground. The 

economic-geology map indicates the location of mineral deposits that are commercially 

valuable. The artesian-water map shows the depth to underground-water horizons. 

Economic-geology and artesian-water maps are included in folios if the conditions in 

the areas mapped warrant their publication. The folios are of special interest to 

students of geography and geology and are valuable as guides in the development astd 

utilization of mineral resources.

The folios numbered from 1 to 163, inclusive, are published in only one form (18 by 

22 inches), called the library edition. Some of the folios that bear numbers higher 

than 163 are published also in an octavo edition (6 by 9 inches). Owing to a fire 

in the Geological Survey Building May 18, 1913, the stock of geologic foUos 

was more or less damaged by fire and water, but the folios are usable and are 

sold at the uniform price of 5 cents each, with no reduction for wholesale orders. 

This rate applies to folios in stock from 1 to 184, inclusive (except reprirts), also the 

library edition of folio 186. The library edition of folios 185,187, and higher numbers 

sells for 25 cents a copy, except that some folios which contain an umisually large 

amount of matter sell at higher prices. The octavo edition of folio 18f and higher 

numbers sells for 50 cents a copy except folio 193, which sells for 75 cents' a copy. If 

34 folios selling at 25 cents each (or their equivalent in higher-priced folios) are ordered 

at one time a discount of 40 per cent is allowed; $5.10 is the minimum amount accepted at this rate.

All the folios contain descriptions of the drainage of the quadrangles. The folios 

in the following list contain also brief discussions of the underground waters in connection with the economic resources of the areas and more or less informatior concerning 

the utilization of the water resources.

An asterisk (*) indicates that the stock of the folio is exhausted.
