o For the purpose of uniformity in the presentation of reports, a general plan has been agreed upon by the 

United States Reclamation Service, the United States Forest Service, the United States Weather Bureau.

Into 12 parts, whose boundaries coincide with natural drainage lines indicated by the parts of the report.

The data presented in these reports were collected by the United 

States Geological Survey under authority implied in the organic law 

(20 Stat. L., p. 394), which contains the following paragraph:

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

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

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

water supply for irrigation.

PUBLICATIONS.

Measurements of stream flow have been made at nearly 2,000 

points in the United States, and also at many points in small areas 

in Seward Peninsula and the Yukon-Tanana region, Alaska, and in 

the Hawaiian Islands. During 1911 gaging stations were maintained 

by the Survey and the cooperating-organizations at about 1,500 points 

in the United States, and many discharge measurements were made 

at other points. In connection with this work data were also collected hi 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 surface water-supply papers 

from time to time. A complete list of the gaging stations maintained 

by the Survey to and including 1910, and a list of the papers relating 

to the water supply of the country, have been published by the Survey 

as Water-Supply Paper 280. An index to the reports containing 

stream-flow measurements prior to 1904 has been published as WaterSupply Paper 119.

For each calendar year there has been prepared a report embodying the stream-flow data collected during that year, which has been 

published either as a part of the Annual Report of the Director, as a 

bulletin, or as a water-supply paper, as shown by the following table:

EXPLANATION OF DATA.

The data presented in this report cover the year beginning October 

1, 1910, and ending September 30, 1911, and not, as in previous 

reports, the calendar year. At the 1st of January in most parts of the 

country a large amount of precipitation for the preceding three 

months is stored, either as ground water in the form of snow or in 

lakes. This stored water passes off in the streams during the spring 

break-up. At the end of September the only stored water available 

for run-off in the streams is possibly a small amount held in ground 

storage. Therefore the run-off for a year, beginning with October 1, 

is practically all derived from precipitation occurring within that year.

For each regular current-meter gaging station the following data, so 

far as available, are given: Description of the station, list of discharge 

measurements, table of daily gage heights, table of daily discharge, and 

table of monthly and yearly discharges and run-off. For stations 

located at weirs or dams the gage-height table is omitted.

In addition to statements regarding the location and installation 

of current-meter stations, the descriptions give information in regard 

to any conditions which may affect the constancy of the relation of 

gage height to discharge, covering such points as ice, logging, shifting channels, and backwater; also information regarding diversions 

which decrease the total flow at the measuring section. Statements 

are also made Tegarding the accuracy and reliability of the data.

The table of daily gage heights records the daily fluctuations of the 

surface of the river as found from the mean of the gage readings taken 

each day, usually in the morning and in the evening. The gage 

height given in the table represents the elevation of the surface of 

the water above the zero of the gage. All gage heights affected by 

the presence of ice in the streams or by backwater from obstructions 

are published as recorded, with suitable footnotes. The rating table 

is not applicable for such periods unless the proper corrections to the 

gage heights are known and applied. Attention is called to the fact 

that the zero of the gage is placed at an arbitrary datum and has no 

relation to zero flow or the bottom of the river. In general, the zero 

is located somewhat below the lowest known flow, so that negative 

readings shall not odcur.

The discharge measurements and gage heights are the base data 

from which rating tables, daily discharge tables, and monthly discharge tables are computed.
20 SURFACE WATER SUPPLY, 1911, PART XII.

The rating table gives, either directly or by interpolation, the discharge in second-feet corresponding to every stage of the river recorded 

during the period for which it is applicable. It is not published in 

this report, but can be determined from the tables of daily gage 

heights and daily discharge as follows:

First plot the discharge measurements for the current and earlier 

years on cross-section paper, with gage heights in feet as ordinates 

and discharge in second-feet as abscissas. Then tabulate a number 

of gage heights taken from the daily gage-height table for the complete range of stage given and the corresponding discharges for the 

days selected from the daily discharge table and plot the values on 

cross-section paper. The last points plotted will define the rating 

curve used and will lie among the plotted discharge measurements. 

After drawing the rating curve, a table can be developed by scaling 

off the discharge in second-feet for each tenth foot of gage height. 

These values should be so adjusted that the first differences shall 

always be increasing or constant, except for known backwater 

periods.

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

corresponding to the observed gage heights as determined from the 

rating tables.

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

gives the mean flow, as determined from the rating table, for the day 

when the mean gage height was highest. As the gage height is the 

mean for the day, it does not indicate correctly the stage when the 

water surface was at crest height, and the corresponding discharge 

was consequently larger than given in the maximum column. Likewise, in the column of "Minimum" the quantity given is the mean 

flow for the day when the mean gage height was lowest. The column headed "Mean" is the average flow in cubic feet for each second 

during the month. On this the computations for the remaining 

columns, which are defined on page 17, are based.

The field methods used hi the collection of the data presented in 

this series of reports are described in the introductory sections of 

Water-Supply Papers 261 to 272, inclusive, "Surface water supply 

of the United States, 1909." Plates I and II show the average precipitation and run-off in the United States as determined from the 

measurements of stream flow made by the Geological Survey and

ACCURACY OF FIELD DATA AND COMPUTED RESULTS.

The accuracy of stream-flow data depends primarily on the natural 

conditions at the gaging station and on the methods and care with 

which the data are collected. Errors of the first group depend on 

the degree of permanency of channel and of permanency of the relation between discharge and stage.

Errors of the second class are due, first, to errors in observation of 

stage; second, to errors in measurements of flow; and, third, to errors 

due to misinterpretation of stage and flow data.

In order to give engineers and others information regarding the 

probable accuracy of the computed results, footnotes are added to the 

daily discharge tables, stating the probable accuracy of the rating 

tables used, and an accuracy column is inserted in the monthly discharge table. For the rating tables "well defined" indicates, in 

general, that the rating is probably accurate within 5 per cent; 

"fairly well defined," within 10 per cent; "poorly defined" or "approximate," 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 accuracy column in the monthly discharge table does not 

apply to the maximum or minimum nor to any individual day, but 

to the monthly mean. It is based on the accuracy of the rating, the 

probable reliability of the observer, and knowledge of local conditions. In this column A indicates that the mean monthly flow is 

probably accurate within 5 per cent; B, within 10 per cent; C, within 

15 per cent; D, within 25 per cent. Special conditions are covered 

by footnotes.

Even though the monthly -means for any station may represent 

with a high degree of accuracy the quantity of water flowing past 

the gage, the figures showing discharge per square mile and depth of 

run-off in inches may be subject to gross errors which result from 

including in the measured drainage area large noncontributing districts or omitting estimates of water diverted for irrigation or other 

use, and they should therefore be considered as only approximate, 

particularly for periods of irrigation or of low water. For these 

errors it is as a rule not feasible to make adequate correction.

In general the base data collected each year by the Survey engineers are published not only to comply with the law but to afford 

any engineer the means of examining and adjusting to his own needs 

the results of the computations. The table of monthly discharge is so 

arranged as to give only a general idea of the flow at the station and 

should not be used for other than preliminary estimates. The determinations of daily discharge allow more detailed studies of the variation in flow by which the period of deficiency may be determined.
22 SURFACE WATEE SUPPLY, 1911, PART XII.

It should be borne in mind that the observations in each succeeding 

year may be expected to throw new light on data already collected 

and published, and the engineer who makes use of the figures presented in these papers should verify all ratings and make such 

adjustments for earlier years as may seem necessary.

COOPERATION AND ASSISTANCE. 

CONDITIONS OF COOPERATIVE WORK.

During the year ending September 30, 1911, the work in Oregon, 

Washington, Idaho, and Montana has been done under cooperative 

agreements between the United States Geological Survey and the 

respective States.

In this work the State is the chief beneficiary, for its interest in 

obtaining a thorough and reliable knowledge of its water resources is 

paramount. At a very moderate cost for field work the State procures the services of men already trained in collecting and analyzing 

the fundamental data, and after the material has been gathered it is 

published without additional expense on the part of the State.

In general the cooperative agreements specify that the United 

States Geological Survey shall allot from its appropriation a sum 

equal to that appropriated from State funds; but to obtain results 

at all commensurate with public needs it has been necessary to expend 

a much larger sum.

The United States Reclamation Service, which is a heavy investor 

in the development of the water resources of the Western States, 

has been so handicapped by a lack of physical data that it has been 

forced to expend from its own fund considerable money for investigations of this kind. The United States Indian Office also, in the development of projects for the benefit of the Indians, has found it necessary to make certain investigations of water supply. As these investigations are closely allied with the collection of statistics of rain and 

snowfall, the cooperation of the United States Weather Bureau has 

been enlisted to a small extent. The engineers of the Geological 

Survey in their regular field work are able to install and inspect some 

of the rainfall stations maintained by the Weather Bureau with but 

little loss of time. Under agreements with the Reclamation Service 

and with the Office of Indian Affairs the work has been performed 

under the direction of the engineers of the Geological Survey. Careful cost accounts have been kept of this work and repayments made 

to the Geological Survey of the amounts represented.

In order to determine the run-off from drainage areas in western 

forest reserves, cooperation has been entered into between the United 

States Geological Survey and the Forest Service. The gages are read, 

as a rule, by forest rangers or persons in the immediate vicinity of the
COOPERATION AND ASSISTANCE. 23

stations if possible. Discharge measurements are made by engineers 

appointed and paid by the Forest Service. These engineers are 

instructed and their work is supervised by engineers of the United 

States Geological Survey. The final records are studied, ratings are 

made, and the results are published by the Geological Survey.

Cooperation with the States is effected under contracts which are 

made between the Director of the Federal Survey and the State 

engineers or other officials and are authorized by legislative acts 

appropriating moneys. The State contracts are essentially of the 

same order, the principal provisions being substantially as follows:

1. The United States Geological Survey retains direct supervision 

of the field work and the preparation of the data for publication.

2. The Federal Survey retains possession of all material collected 

field notes, maps, etc. but this material is open at all times to 

inspection by the State officials, and if not satisfactory the agreements 

^can be terminated at any time.

3. The salaries of gage observers and the salaries and traveling and 

field expenses of the engineers are divided between the two parties in 

some manner agreed upon, the accounts being rendered monthly in 

accordance with the regulations of the Federal Survey.

4. The streams and localities in which investigations shall be made 

are determined by conference between the State officials and the 

representatives of the United States Geological Survey.

5. The cost of publication is borne entirely by the Federal Survey.

United States Geological Survey, made up of several sections attached to the 

piling of the viaduct connecting Regulator Dock with the warehouse; the United 

States Army Engineers' gage, similar in form but with a datum 8.9 feet lower than 

the Brooks gage. Gage at Cascade Locks is attached to the side of wooden fender 

of upper locks chamber between upper guard and locks gates. Elevation of gage 

datum at Cascade Locks, 42.5 feet above sea level, except December 1, 1896, to 

December 31, 1899, when datum was N 60 feet lower. Elevation of datum of 

Brooks gage, 45.6 feet.

Channel. Rocky and pennanent at the rapids at Cascade Locks the control for all 

three gages.

Discharge measurements. In 1903 made by United States engineers with rod 

floats and meter from a steamer. In 1907 by United States Geological Survey 

engineers with meter from a launch. In 1908 flood measurements by United 

States Geological Survey engineers 2,000 feet below the gage at The Dalles.

Accuracy. Results good.

Cooperation. Station has been maintained in cooperation with the United States 

Weather Bureau and the United States Engineer Corps.

CLARK FORK NEAR PLAINS, MONT.

Location. At Cooper's Ferry, in lot 7, sec. 7, T. 19 N., R. 26 W., about 3 miles

above Plains, Mont., and about 7 miles below the mouth of Flathead River. 

Records available. October 28, 1910, to September 30, 1911. 

Drainage area. 19,900 square miles. 

Gage An overhanging chain gage on the right bank, about 150 feet below the ferry

cable.

Channel. Practically permanent. 

Discharge measurements. Made from ferry cable. 

Winter flow. Stream freezes over at the gage for short periods during the winter,

but is open at control section below gage. Relation between gage height and

discharge little, if any, affected by ice. 

Diversions. A number of small ditches take water for irrigation from tributaries of

Flathead River and headwaters of Clark Fork. 

Accuracy. Rating curve good, but gage-height record somewhat doubtful at times.

RACETRACK CREEK NEAR ANACONDA, MONT.

Location. In sec. 15, T. 6 N., R. 11 W., directly above the falls in Race Track 

Creek about 3 miles above the Race Track ranger station and 17 miles from Anaconda, near the head works of the State of Montana power flume.

Records available. July 11 to October 31, 1911.

Drainage area. 38 square miles.

Gage. Vertical staff fastened to a tree and ledge rock on left bank.

Channel. Rock; probably permanent. Channel at gage divided by a large rock.

Discharge measurements. Made by wading.

Winter now. Seriously affected by ice.

Diversion. Water diverted above station for mining. A placer ditch takes out 

immediately below. The State of Montana is building a flume to carry water 

from a point near the gage for development of power to light the State buildings 

at Deer Lodge. Below the station nearly the entire flow is diverted from the 

stream for irrigation.

Accuracy. Results poor. Gage heights affected by diversion of water from one 

channel to the other by means of ice or debris lodging across either channel.

Cooperation. Field data furnished by the United States Forest Service.

SNAKE KTVEH 1 NEAR MOEAN, WYO.

Location. In sec. 17, T. 45 N., R. 114 W. sixth principal meridian, about 1J miles 

below Moran post office and the United States Reclamation Service dam at the 

outlet to Jackson Lake.

Records available. September 21, 1903, to September 30, 1911.

Drainage area. 820 square miles.

Gage. Inclined staff gage on the left bank; datum unchanged.

Channel. Gravel and bowlders. Practically permanent since 1909 and will probably continue so with the water controlled as it is.

Discharge measurements. Made from a cable and car about 100 feet below the 

gage and, at low stages, by wading.

Winter flow. Relation between gage heights and discharge not affected by ice.

Diversions and storage. No important tributaries and no diversions between the 

dam and the station, and practically no diversions from the river above the lake. 

Storage capacity of the reservoir with the dam at its present elevation, 400,000 

acre-feet.

Accuracy. Rating curve well denned; results good.

Cooperation. Gage heights furnished by the Reclamation Service.

SNAKE RIVER 1 NEAR HEISE, IDAHO.

Location. In sec. 5, T. 3 N., R. 41 E., Boise meridian, about 600 feet above the 

Anderson dam, a crib and stone diversion structure, about 3 miles above Heise 

and about 25 miles below the Lyon station. Several small creeks enter between 

the Lyon and Heise stations.

Records available. September 25, 1910, to September 30, 1911.

Drainage area. Not measured.

1 Formerly called South Fork of Snake River.
268 SURFACE WATER SUPPLY, 1911, PART XII.

Gage. Vertical staff on left bank.

Channel. Channel under the cable shifts; relation of gage height to discharge controlled by Anderson dam. This relation has been affected at times by repair 

work on the dam and damage to the crest by high water and ice.

Discharge measurements. Made from a cable about 100 feet below the gage.

Winter flow. Affected by ice.

Diversion and storage. Station is above all the main diversions from Snake 

River. A small ditch diverts water around the station, but its maximum capacity is probably not 20 second-feet. The only water stored above the station 

is at Jackson Lake, Wyo., where the Reclamation Service dam can at present 

store abont 400,000 acre-feet.

Accuracy. Records impaired by ice gorges in the winter and by damage to the 

crest of the dam by ice and floods.

274 SUEFACE WATER SUPPLY, 1911, PAKT XII.

SNAKE RIVER AT HO WELL'S FERRY, NEAR MINIDOKA, IDAHO.

Location. In sec. 2, T. 9 S., R. 25 E., Boise meridian, 100 yards below Howell's 

ferry, about 1 mile below the Reclamation Service dam and about 6 miles south 

of Minidoka post office, the nearest railroad point. About 6 miles above the 

Montgomery's ferry station, discontinued December 31, 1910. Raft River enters 

between the Neeley and Minidoka stations.

Records available. April 21, 1910, to September 30, 1911.

Drainage area. Not measured.

Gage. Lietz automatic gage installed August 28, 1911, on the right bank referred 

to and directly across the river from the staff gage used previous to August 28, 

1911.

Channel. Coarse gravel; shifts slightly but infrequently.

Discharge measurements. Made from a cable about 50 feet below the gage.

Winter flow. Relation between gage height and discharge is somewhat affected 

by ice.

Diversions and storage. The North Side and South Side Minidoka canals divert 

between Neeley and the Minidoka station. No diversions between the station 

and the Twin Falls North Side and South Side canals at Milner. About 54,000 

acre-feet storage is possible at Minidoka dam.

Accuracy. Conditions for measuring discharge good; records reliable for greater part 

of year.

Cooperation. Expense of maintenance borne by the United States Reclamation 

Service.

SOUTH SIDE MINIDOKA CANAL NEAR MINIDOKA, IDAHO.

Location. In sec. 12, T. 9 S., R. 25 E., Boise meridian, about 300 yards below the

Minidoka dam and about 6 miles south of Minidoka. 

Records available. April 21, 1909, to December 31, 1911. 

Gage. Friez automatic. Position of gage was changed between the seasons of 1909

and 1910, the gage being moved 200 or 300 feet farther down the canal. Datum

unchanged since the spring of 1910. 

Channel. Canal section is in earth and may shift. The canal was widened below

the station during the winter of 1910-11, changing the relation of gage height to

discharge. 

Discharge measurements. Made from a suspension footbridge a few feet above

the gage. 

Accuracy. Grade of the canal is light and velocities are low, but records are believed

to be reliable. Conditions have, however, necessitated the use of several rating

curves. 

Cooperation. Expense of maintenance borne by the Reclamation Service.

NOTE. Gage heights Apr. 10 to July 31 are daily readings; those for Aug. 1 to Sept. 30 are the means of 

two readings per day.

SNAKE RIVER AT MILNER, IDAHO.

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

river receives no tributaries between this station and the one above.

Records available. May 10, 1909, to September 30, 1911.

Drainage area. Not measured.

Gage. Inclined staff on the left bank read at low and medium stages; vertical 

section read at high stages. This gage was installed October 20, 1909, and set to 

read the same on that date as the gage previously used, which was located about 

100 yards upstream. During parts of the irrigating season, owing to the small 

flow of water, a temporary station is maintained about 100 yards below the main 

gage.
COLUMBIA EIVEE BASIN. 281

Channel. In lava rock canyon; fairly permanent.

Discharge measurements. Made from a cable at the gage and from foot planks

at the temporary low-water station. 

Winter flow. Not materially affected by ice. 

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

station and at times during the irrigating season practically the whole flow of

the river is taken. 

Accuracy. Conditions for determining discharge are poor, but the records are

believed to be fairly reliable. 

Cooperation. Maintained in cooperation with the Twin Falls North Side Land &

Water Co. and the Twin Falls Canal Co.

NOTE. Discharge determined from several fairly well defined rating curves and by indirect method for 

shifting channels.
COLUMBIA RIVER BASIN. 283

NORTH SIDE TWIN FALLS CANAL AT MILNER, IDAHO.

Location. In sec. 20, T. 10 S., R. 21 E. Boise meridian, at a highway bridge about 

three-fourths of a mile below the headgates at the Milner dam.

Becords available. May 10, 1909, to September 30, 1911.

Gage. Vertical staff; datum unchanged.

Channel. Permanent, but is badly covered with moss during certain seasons of the 

year; during winter of 1909-10 canal was lined with concrete.

Discharge measurements. Made from cable about 150 feet below gage.

Winter flow. Not affected by ice.

Accuracy. Individual measurements can be made with a fair degree of accuracy, 

but the daily discharge estimates are approximate at times on account of the 

unusually variable relation between gage height and discharge, caused principally by the moss growth, but perhaps in some measure by changes in entrance 

velocity at the head gates or other unexplained phenomena. Monthly estimates, however, are based on sufficient actual measurements to be fairly reliable.

Cooperation. Many of the discharge measurements were furnished by the Twin 

Falls North Side Land & Water ,Co. and the gage heights by the Twin Falls 

Canal Co.

Discharge measurements of North Side Twin Falls canal at Milner, Idaho, in the year

ending Sept. 30, 19-11.

SNAKE RIVER AT WEISER, IDAHO.

Location. In sec. 31, T. 11 N., R. 5 W., Boise meridian, about 200 yards downstream

from the wagon bridge at Weiser, and about 1 mile below the mouth of Weiser

River. 

Records available. October 8, 1910, to September 30, 1911. The United States

Weather Bureau has obtained gage heights at a gage about half a mile above the

Survey gage for parts of almost every year since 1895. 

Gage. Sloping gage on the right bank; datum unchanged. 

Channel. Rocks and coarse gravel; should be fairly permanent. 

Discharge measurements. Made from a cable a few feet below gage. 

Diversions. Some water for irrigation diverted between Bang Hill and Weiser, but

almost entirely by pumping. 

Accuracy. Conditions for determining flow good; records reliable.

Discharge measurements of Snake River at Weiser, Idaho, in the year ending Sept. 30,1911.

SNAKE RIVER NEAR BURBANK, WASH.

Location. At the head of Fivemile Rapids, 1,500 feet above the intake of the power 

canal about If miles above the power plant of the Burbank Power & Water Co., 

about 5 miles east of Burbank and 5J miles above the mouth of the river.

Records available. September 1, 1909, to September 30, 1911; fragmentary gage 

records October 2, 1907, to August 31, 1909. Readings on a gage below the rapids 

in the tailrace of the power plant, June 24, 1909, to October 31, 1910.

Drainage area. 108,600 square miles.

Gage. Inclined staff on right bank reading from 334 to 352 feet, sea-level datum. 

The datum of the published gage heights is 300 feet above sea level. The gage 

in the tailrace of the power plant reads sea-level elevation also.

Channel. The control for the gage is the head of the rapids. The plotting of the 

discharge measurements indicates that the control has remained practically 

constant since about August, 1909. During that month a wing dam was constructed at the head of the power canal which raised the water at the gage a 

small amount.

Discharge measurements. Made from a bridge on the Pendleton branch of the 

Northern Pacific Railway about one-fourth mile above the mouth of the stream. 

A gage reading to 28 feet is attached to the bridge, but is affected by backwater 

from the Columbia.

Winter flow. Not affected by ice.

Accuracy. Rating curve well defined between 20,000 and 240,000 second-feet. 

Records for September and October, 1909, may have been affected by construction work on the wing dam, and their accuracy has been reduced.

Cooperation. Gage-height record furnished by the Burbank Power & Water Co.

HENRYS FORK 1 AT WARM RIVER, IDAHO.

Location. In sec. 12, T. 9 N., R. 43 E. Boise meridian, about half a mile from the 

Warm River railroad station, and about 300 yards above the mouth. of Warm 

River; above all main tributaries.

Records available. September 3, 1910, to September 30, 1911.

Drainage area. Not measured.

Gage. Vertical staff on left bank; datum unchanged.

Channel. Gravel and sand; moss; bottom shifts slightly.

Discharge measurements. Made from a cable at the gage.

Diversions. Practically no water diverted above the station; no storage yet provided.

Winter flow. Relation between gage heights and discharge not appreciably affected 

by ice.

Accuracy. Records good, though determination of daily discharge may be approximate for short periods during which moss exists in the channel.

HENEYS FOEK NEAR REXBTJEG, IDAHO.

Location. In sec. 30, T. 6 N., B. 39 E. Boise meridian, just below the highway 

bridge 7 miles due west of Rexburg. No tributaries between this station and 

the junction of the North and South Forks of Snake River. About 1 mile above 

the station the south channel of the Teton enters North Fork, and 7 miles above 

the main Teton or Pierre River'enters. Fall River enters about 20 miles and 

Warm River about 35 miles above.

Records available. April 13, 1909, to September 30, 1911.

Drainage area. Not measured.

Gage. Vertical staff on right bank about 150 feet below the bridge. In 1912 the 

gage was found to be approximately 0.7 foot low, but measurements seemed to 

indicate that practically all of this shift occurred during the winter of 1911-12.

Channel. Shifting gravel.

'Winter flow. Affected by ice.

Discharge measurements. Made from a cable about one-fourth mile below gage 

or from the highway bridge. At high stages water overflows both banks, and 

at a few points the direction of the current is not exactly normal to the cable. 

These angles, however, are taken into account in the computations.

Diversions. No diversions from the North Fork below the station; most of the water 

used above the station is taken from the tributaries.

Accuracy. Estimates of daily discharge probably approximate for greater part of 

time; monthly means should be fairly reliable.

NOTE. See footnote to table of daily discharge.

BLACKFOOT RIVER NEAR HENRY, 1 IDAHO.

Location. In sec. 11, T. 5 S., R. 40 E. Boise meridian, about 200 feet below the 

wagon bridge at Rockyford crossing, about 1 mile below Blackfoot Marsh dam of 

the Indian Service, and about 30 miles south of Soda Springs, the most convenient railroad station. Henry post office is about 12 miles southeast of the dam. 

Only a small amount of seepage enters the river between the dam and the station.

Records available. July 15, 1908, to September 30, 1911.

Drainage area. Not measured.

Gage. Vertical timber of left bank.

Channel. Lava bowlders, gravel, and bedrock; practically permanent. Moss exists 

in the stream bed during certain periods.

Discharge measurements. Made by wading or, when necessary, from a cable 

immediately below the gage.

Winter flow. Affected by ice.

Diversions. No water is diverted between the dam and the station and practically 

none between the dam and the Shelley station below.

Accuracy. The daily estimates for this station are approximate at times because of 

the presence of ice or of moss in the channel, but sufficient measurements have 

been made to make the monthly estimates reliable. A rough check can be made 

on the estimates from the record of the gate openings at the dam.

Cooperation. Gage-height records furnished and expense of maintenance borne by 

the Office of Indian Affairs.

Discharge measurements of Blackfoot River near Henry, Idaho, in the year ending Sept.

30, 1911.

NOTE. Discharge for periods in which channel was unobstructed determined from a well-defined rating 

curve. This curve was used Nov. 6 to Dec. 10, Jan. 1 to 22, Jan. 24 to Feb. 16, and Feb. 24 to July 4. Estimates of daily discharge Oct. 1 to Nov. 5 are roughly approximate and not considered of sufficient accuracy 

for publication. Mean discharge for October estimated at 24.9 second-feet; Nov. 1 to 5 and Deo. 6 to 9 and 

11 to 31, 28 second-feet. These estimates are based on studies of elimatologic records, observer's notes, and 

hydrograph comparison with the Shelley station. Discharge also estimated for Jan. 23 and Feb. 17 to 23. 

Discharge July 5 to Sept. 30, when gage heights were affected by growth of moss, obtained directly from 

meter measurements, and for intervening periods from a fairly well defined rating curve.

BLACKFOOT RIVER NEAR SHELLEY, IDAHO.

Location. In sec. 7, T. 2 S., R. 38 E. Boise meridian, about 1£ miles above the 

mouth of the canyon, and about 3 miles above the N. A. Just ranch, 10 miles 

southeast of Shelley post office, and about 18 miles northeast of Blackfoot. Below 

all important tributaries; Wolverine Creek enters about 1J miles above.
COLUMBIA EIVEE BASIN. 301

Records available. June 26, 1909, to September 30, 1911. Records were obtained 

at Presto, about 5 miles below, from April 17, 1903, to-December 31, 1909. No 

tributaries enter between the two stations, but during the irrigation season four 

small canals divert about 50 second-feet of water.

Drainage area. Not measured.

Gage. A Friez automatic gage on the right bank, outside staff gages of which there 

are two, one inclined, and one vertical in a barrel stilling well. Both gages are 

set to same datum, which has remained unchanged since the gages were established.

Channel. Practically permanent but somewhat rough.

Discharge measurements. Made from cable about 10 feet below the gage house.

Winter flow. Gage heights somewhat affected by ice.

Diversions and storage. No diversions of any importance above the station. The 

entire flood flow of the river is stored behind the Indian Service dam 40 miles 

above.

Accuracy. Rough cross section makes accurate low-water measurements difficult.

Cooperation. Expense of maintenance borne by the Office of Indian Affairs.

BIG LOST RIVER NEAR CHILLY, IDAHO.

Location. In sec. 30, T. 8 N., R. 21 E. Boise meridian, at Howell's ranch, about 

12 miles from Chilly post office and about 30 miles up the river from Mackay, 

the nearest railroad point.

Records available. April 25, 1904, to August 31, 1906, and from July 1, 1907, to 

November 11, 1911, excepting winter months.

Drainage area. Not measured.

Gage. Vertical staff on left bank, directly back of Howell's shop.

Channel. Coarse gravel; fairly permanent.
COLUMBIA EIVEB BASIN. 303

Discharge measurements. Made from a cable about half a mile below the gage.

Winter flow. Winter records not kept at this station, but a measurement made 

December 19, 1910, under conditions normal to winter gave a discharge of 67.9 

second-feet for a gage height of 2.98 feet, measured to top of water in a hole cut 

through 1 foot of ice at the gage. Total ice cover at the gage; riffles below partly 

open.

Diversions. Two small ditches divert at times between the gage and the cable, 

but their combined capacity is probably not over 5 second-feet. Several small 

ditches divert water between the station and Mackay, but practically no water 

is diverted above the1 station.

Accuracy. Sufficient measurements have been made to afford data for reliable

estimates of discharge during the periods for which gage heights were obtained.

The water that sinks in places between this station and the Mackay Dam site rises

again wholly or in part above the dam site. 

In this stretch are several tributaries. Thousand Springs Creek, carrying on

September 10, 1911, a measured flow of 56 second-feet, and Warm Springs Creek

an estimated flow of 30 second-feet on August 4, 1910, have fairly constant discharge.

LITTLE LOST RIVER NEAR CLYDE, IDAHO.

Location. In sec. 18, T. 10 N., R. 27 E. Boise meridian, at the Mulkey ranch, 1

mile upstream from Clyde post office, which is at the Baringer ranch; above the

mouth of Wet Creek and below Pass Creek. 

Records available. August 28, 1910, to September 30, 1911. 

Drainage area. Not measured. 

Gage. Vertical staff. 

Channel. Gravel; shifts. 

Discharge measurements. Made from a foot log across the stream at the gage or

by wading.

Diversions. Small ranch ditches divert water both above and below the station. 

Accuracy. Owing to shifting character of the stream the daily estimates of discharge

may be only approximate at times, but records on the whole are fairly reliable.

POKTNEUF KIVEB, NEAR PEBBLE, IDAHO.

Location. In sec. 26, T. 7 S., R. 38 E., Boise meridian, at the ranch of W. A. Gamble, 

3 miles north of Pebble post office and about 6 miles below Topons Creek.

Records available. September 8, 1910, to September 30, 1911.

Drainage area. Not measured.

Gage. Vertical staff, in two sections, bolted to rock on left bank about 100 yards 

below the ranch house; datum unchanged.

Channel. Gravel and small bowlders; probably permanent. Moss grows on the 

bottom of the stream,
COLUMBIA RIVER BASIN. 309

Discharge measurements. Made from a suspension footbridge and by wading.

Winter flow. Not much affected by ice.

Diversions and storage. A number of springs exist between the station and a 

storage dam of the Portneuf-Marsh Valley Irrigation Co., about 9 miles above the 

station. Topons Creek is to be diverted into the reservoir, which has a storage 

capacity of about 28,000 acre-feet. The Portneuf-Marsh Valley Irrigation Co.'s 

canal diverts from the river about 14 miles below the station. Small ranch 

ditches take out above and below the station.

Accuracy. The relation of gage height to discharge is at times affected by the growth 

of moss in the channel. Sufficient measurements have been obtained to make 

the computations reliable.

RAFT RIVER NEAR BRIDGE, IDAHO.

Location. In see. 7, T. 15 S., R. 27 E. Boiee meridian, about one-fourth mile above 

the Olson ranch and 2 miles above Bridge poet office.

Becords available. September 18, 1909, to September 30, 1911.

Gages. From September 18, 1909, to February 28,1910, a vertical staff gage located 

at the bridge near Hawking's ranch house was used. This gage was washed out on 

February 28, 1910, and on March 15, 1910, a new gage was installed with datum 

3.42 feet lower. A supplementary gage was also installed in a high-water channel which carried water in 1910 and for some time after the flood. The discharge 

records published for 1910 include the flow in both channels. On January 30, 

1911, the gage was washed out again, the bridge also being carried away. On 

February 24, 1911, a sloping gage was installed on the right bank farther down
COLUMBIA RIVER BASIN. 311

the stream, at the Olson ranch. .The datum of this gage is unrelated to that of 

the old gage at Hawkins's ranch. A supplementary gage is also installed in a 

high-water channel which carries water at flood times unless dammed off. The 

datum of this gage has remained the same.

Channel. Present channel is of gravel and shifts at times. The high-water channel 

is dammed off during the irrigating season, but the dam is likely to go out during 

flood periods.

Discharge measurements. At ordinary stages made by wading; high-water 

measurements must be made from bridges across various sloughs, etc.

Winter flow. Somewhat affected by ice.

Diversions. Most of the small ranch ditches that divert water above the station 

are flood-water rights.

Accuracy. Present station is well rated, and the published records are fairly reliable, especially those derived from observations at the present gage.

NOTE. Discharge determined as follows: Oct. 1 to Dec. 12 from a well-defined rating curve; Mar. 5 to 

May 17 and July 5 to Sept. 30 from a well-defined rating curve; June 10 to 20 from a fairly well-defined 

rating curve; May 18 to June 9 and June 21 to July 4 shifting channel methods were used; mean discharge 

Dec. 13 to 31, Jan. 1 to 25, and Feb. 24 to 28, estimated at 20 second-feet; Mar. 1 to 4 estimated as given. 

Data insufficient to make reliable estimates for the high-water period of Jan. 26 to Feb. 11. The above 

estimates do not include flow in the flood channel. A gage record was obtained for flood channel from 

Feb. 24 to Apr. 10 when the channel was dry. No measurements were made of the flood channel, but the 

discharge for Feb. 24 to Apr. 10 has been estimated roughly at 350 acre-feet.

CASSIA CKEEK NEAK CON ANT, IDAHO.

Location. In sec. 19, T. 13 S., R. 26 E. Boise meridian, about 200 yards below the 

point at which the road crosses the creek at the ranch of Mrs. E. F. Conant, and 

about 1 mile above Conant post office; below all tributaries.

Records available. September 18, 1909, to September 30, 1911.

Drainage area. Not measured.

Gage. Vertical staff on left bank about 10 feet above the suspension footbridge. 

Gage has raised at various times, but gage heights as published have been reduced 

as nearly as possible to original gage datum.

Channel. Gravel; shifts.

Discharge measurements. Made from a suspension footbridge and wading.

Winter flow. Ice forms at the gage in winter.

Diversions. Ranch ditches divert both above and below the station.

Accuracy. Records are approximate for part of the time, as the conditions of the 

gage and channel were unstable and gage readings were unreliable.

SALMON FALLS CREEK NEAR SAN JACINTO, NEV.

Location. In sec. 23, T. 47 N., R. 64 E. Mount Diablo base and meridian, at the 

upper end of the canyon, just below the mouth of Shoshone Creek: about 6 

miles north of San Jacinto; above the backwater from Salmon dam about 20 

miles down the river.

Records available. September 17, 1909, to September 30, 1911. Records from 

May 31, 1909, to May 28, 1910, obtained just above dam, at a station known 

as Salmon Falls Creek near Twin Falls; no diversions and no important tributaries between the two stations.

Drainage area. Not measured.

Gage. Friez automatic gage installed June 5, 1910. A staff gage a short distance 

upstream and at different datum, was used September 17, 1909, to June 30, 1910.

Channel. Hard bottom with a few rocks; fairly permanent.

Discharge measurements. Made from a cable 10 feet below the gage or, at low 

stages, by wading.

Winter flow. Affected by ice at times.

Diversion and storage. Ranch ditches divert water above the station. The dam 

of the Twin Falls Salmon River Land & Water o. will store all the water in 

Salmon Falls ,River, and the records of this station will indicate practically the 

entire amount running into the reservoir.

Accuracy. Rating curves change somewhat, but records are reliable.

Cooperation. Gage heights furnished by the Twin Falls Salmon River Land & 

Water Co.

BIG WOOD RIVER NEAR SHOSHONE, IDAHO.

Location. In sec. 17, T. 5 S., R. 17 E. Boise meridian, at a private wagon bridge 

at A. D. Silva's ranch, 1 mile below the steel wagon bridge and 7 miles northwest of Shoshone; 24 miles below Magic dam. No tributaries between this station and the one below North Gooding diversion.

Records available. June 5, 1905, to September 30, 1911.

Drainage area. Not measured.
336 SURFACE WATER SUPPLY, 1911, PART XII.

Gage. Vertical staff on right bank about 10 feet below the private bridge built in 

the fall of 1910.

Channel. Smooth and permanent, except for temporary obstructions in May and 

June, 1911. :

Discharge measurements. Made from a cable about 100 yards above gage.

Diversions. No important diversions between the North Gooding station and the 

ditch at Silva's ranch; ranch ditches divert below.

Accuracy. Results are reliable except for May and June, 1911. Accuracy of records for periods during which ice was present somewhat approximate. Records 

for period during and since the construction of Magic dam may contain errors, 

due to the artificial control.

NOTE. Discharge determined as follows: Oct. 1 to Dec. 20, Feb. 27 to May 15, and June 14 to Sept. 30. 

from a rating curve well defined above 20 second-feet; May 20 to June 12, from a rating curve well defined 

between 1,000 and 1,500 second-feet. Unstable conditions apparently existed May 20 to June 12, and the 

accuracy for those months has been reduced. Mean discharge Dec. 21 to 31 estimated at 45 second-feet; 

January, 50 second-feet; Feb. 1 to 9, 60 second-feet; Feb. 26, 400 second-feet. Shifting-channel methods 

used May 16 to 19, and June 13; discharge June 9 to 10 estimated from measurements.

ALKALI CREEK NEAR GLENNS FERRY,, IDAHO.

Location. In sec. 27', T. 5 S., R. 9 E. Boise meridian, where the county road from 

Glenns Ferry to Hammett crosses Alkali Creek, about 3 miles west of Glenns 

Ferry; below all tributaries.

Records available. November 20, 1909, to April 23, 1910; December, 1910; January 25 to June 15, 1911 (gage heights and measurements only during 1911).

Drainage area. 38 square miles.

Gage. Staff gage originally at the ford. During summer of 1910 a new bridge was 

built, and on January 25, 1911, a gage was spiked to the downstream side.
COLUMBIA RIVER BASIN. 343

Channel. Gravel; may shift; control artificial in 1911; railroad dike below.

Discharge measurements. Made by wading, or from the bridge at flood stages.

Winter flow. Affected by ice.

Artificial control. During the irrigating season a large part of the flow is maintained by irregular leakage and waste from the Kings-Hill Extension Irrigation 

Co.'s canal which crosses the creek in a flume above the gaging station. The 

amount of water from the canal varies also, and the normal flow of the creek is 

not definitely known.

Accuracy. Results are approximate.

Cooperation. Gage heights have been furnished by the Kings-Hill Extension 

Irrigation Co. No estimates of flow have been made for 1911 because of lack of 

data.

BRUNEAU RIVER NEAR HOT SPRING, IDAHO.

Location. In sec. 34, T. 7 S., R. 6 E. Boise meridian, at Dunham's ranch, about 

2 miles above Hot Spring post office; below all important tributaries except 

Jacks and Wickahoney creeks.

Records available. July 3, 1909, to September 30, 1911,

Drainage area. Not measured.
350 SURFACE WATER SUPPLY, 1911, PART XII.

Gage. A vertical staff on the right bank. The original gage, a vertical staff on 

right bank, about one-quarter mile above Dunham's house, was destroyed by 

flood March 2, 1910; on March 12, 1910, the gage was re-established close to Dunham's house at the end of the rocky cliff which is on the left bank of the stream. 

 The datum of the present gage is unrelated to that of the original gage.

Channel. Coarse gravel and rocks; control shifts at times.

Discharge measurements. Made from the cable at the gage or, when stage permits, by wading.

Winter flow. Not affected by ice.

Diversions. Small ranch diversions only above the station. Buckaroo ditch diverts 

about 1 mile below the station, and about 20 miles below is the storage and diversion dam of the Owyhee Land & Irrigation Co.

Accuracy. Ratings well defined; records reliable.

Records available. March 26, 1890, to December 31, 1893; January 1, 1895 to

May 15, 1897, and August 27, 1903, to September 30,1911. 

Drainage area. 11,100 square miles. Area approximate and should be used with

caution. Watershed not well defined on available maps. 

Gage. Chain gage on upstream side of highway bridge. 

Channel. Bed of cemented gravel; fairly permanent; one channel only.
864 SUEFACE WATER SUPPLY, 1911, PART Xtt.

Discharge measurements. Made from highway bridge and by wading.

Diversions. The Owyhee canal diverts water from left bank about 6 miles above 

the station. Practically all the normal low-water flow is taken; maximum diversion by this canal approximately 250 second-feet.

Winter flow. Gage heights affected for short periods by ice, but not seriously.

Accuracy. Conditions unfavorable for accurate measurements at very low stages; 

higher stage records, of paramount interest at this station, probably reliable.

BOISE RIVER NEAR HIGHLAND,, IDAHO.

Location. In sec. 32, T. 3 N., R. 4 E. Boise meridian, about one-fourth, mile above 

Smythe's ranch and one-half mile below Kirk's ranch (the old Kunzi ranch). 

About 3 miles southwest of the old Highland post office and about 1 mile above 

Gooseneck, the nearest station on the Boise & Arrowrock Railroad; about 8 

miles above the old station near Boise, which it replaced on July 27, 1905; 2J 

miles below the mouth of Moores Creek and below all important tributaries.

Records available. December 15, 1894, to October 31, 1904, at the old station; 

from March 18, 1905, to September 30, 1911, at the present station. '

Drainage area. 2,650 square miles.
372 SURFACE WATER SUPPLY, 1911, PART XII.

Gage. March 18 to July 31, 1905, gage heights obtained from a temporary gage 

on the right bank below Smythe'a house; from August 1, 1905, to November 

21, 1909, -a sloping gage on the right bank about one-fourth mile above Smythe's 

house at different datum; from November 22, 1909, to September 30, 1911, a 

vertical staff gage on left bank and about 50 feet farther upstream. Reads the 

same as gage across river at low stages but differs at high stages.

Channel. Rough, with bowlders and gravel. Control changes during high water, 

filling in and cutting out, but seems to return to a condition of equilibrium after 

each high-water stage.

Discharge measurements. Made from a cable about 100 feet above the present

Diversions. Practically no water is diverted above the station. Low-water flow 

is all diverted farther down during the irrigating season.

Accuracy. Enough measurements have been made to insure a reliable record even 

for periods of shifting channel. Relation between gage height and discharge 

is somewhat affected by ice.

Cooperation. Some of the discharge measurements have been furnished and the 

expense of maintaining this station has been borne by the United States Reclamation Service.

Discharge measurements of Boise River near Highland, Idaho, in the year ending Sept.

SO, 1911.

Location. In sec. 24, T. 2 N., R. 6 E. Boise meridian, at R. S. Sandlin's ranch, 

about 1 mile above the mouth of Smiths Creek, about 3 miles above the flow line 

of the Arrowrock reservoir, 13 miles above the mouth of the South Fork, and 

about 18 miles above the Arrowrock dam; about 7 miles from Prairie post office. 

Smiths Creek, Long Gulch, and Rattlesnake Creek enter between the station 

and Boise River.
374 SURFACE WATER SUPPLY, 1911, PART XII.

Records available. March 24 to September 30, 1911.

Drainage area. 1,090 square miles.

Gage. Sloping gage on right bank.

Channel. Control seems permanent, though bed at the cable IB composed of mud and 

gravel, and cuts out and fills.

Discharge measurements. Made from cable about 75 feet above the gage.

Diversions. No important diversions above or below, the river occupying a canyon 

with sheer walls 400 feet high for a large part of its course.

MALHEUR RIVER AT RIVERSIDE, OREG.1

Location. At the county highway bridge in sec. 22, T. 23 S., E. 37 E., about 1,000 

feet below mouth of the South Fork, and about half a mile west of Riverside post 

office.

Records available. January 16, 1909, to September 30, 1911.

Drainage area. 1,910 square miles. Area approximate, as watershed is not well 

denned on available maps.

' Formerly known as "Middle Fork of Malheur River near Riverside, Oreg."
876 SURFACE WATER SUPPLY, 1911, PART

Gage. Chain gage on downstream side of bridge. Staff gage referred to slightly

different datum used prior to June 12, 1910.

Channel. Gravel and small bowlders; control may be changed by ice jams. 

Discharge measurements. Made from the bridge or by wading. 

Winter flow. Affected by ice.

Diversions. Some water is diverted above for ranches. 

Accuracy. Results good for ordinary stages. Extreme low and high stage records

somewhat uncertain because of lack of discharge measurements at corresponding 

Gage-height record of doubtful accuracy at times.

MALHEUR RIVER AT VALE, OREG.

Location. In sec. 29, T. 18 S., R. 45 E. Willamette meridian, at the highway bridge 

at Vale, Oreg., one-fourth mile below mouth of Bully Creek and 2£ miles above 

the mouth of Willow Creek.

Records available. March 20, 1890, to Sept. 30, 1891; January 1, 1895, to September 30,1896; April 15 to July 31,1897; March 20,1903, to April 1,1907; May 29, 

1908, to September 30,1911.
378 SURFACE WATER SUPPLY, 1911,' PART XII.

Drainage area. 4,860 square miles.1

Gage. Chain gage on. downstream side of bridge. Gage datum unchanged since 

May 20, 1903.

Channel. Gravel; shifts; one channel only.

Discharge measurements. High-stage measurements made from a suspension 

footbridge about one-quarter mile below gage; low-stage measurements can be 

made by wading.

Diversions. Important diversions for irrigation both above and below the station.

Winter flow. Gage heights affected by ice during severe winters.

Accuracy. Records for low stage not satisfactory on account of small shifts in channel; high-stage record probably reliable.

NOTE. The recorded gage heights for Feb. 11 to 26 and Mar. 6 to about Mar. 17 are believed to be unreliable, 

due to either poor gage observations or the presence of an ice jam below.

1 Value published in 1906 report is accepted as probably better than 4,190 as used in 1909 and 1910 reports. 

Area is approximate, asjvatersned is not well defined on available maps.

NOTE. Discharge Oct. 1 to Nov. 19,1910, determined from a fairly well defined rating curve; discharge 

Nov. 20 to 30 estimated as the sum of the discharge of Malheur River at Riverside and North Fork near 

Beulah plus 10 second-feet; discharge for December is the sum of discharge at these two stations plus an 

allowance of 20 second-feet for inflow.

Discharge for the periods Jan. 7 to 23, Jan. 30 to 31, Mar. 18 to May 6, and June 12 to Sept. 30, 1911, 

were determined from four fairly well defined rating curves; mean discharges were estimated as follows: 

Jan. 1 to 6 and 24 to 29,180 second-feet; Feb. 1 to 5,1,400 second-feet; Feb. 6 to 28,360 second-feet; Mar. 1 to 

5,380 second-feet; Mar. 6 to 10,1,500 second-feet; Mar. 11 to 17,1,900 second-feet; May 7 to 31,210 second-feet;

three-quarters of a mile from Riverside post office. 

Records available. May 25, 1910, to September 30, 1911. 

Drainage area. 800 square miles. Area approximate as water shed is not well

defined on available maps.

Gage. Vertical staff in three sections on right bank.

Channel. Gravel and bowlders; free from vegetation and not likely to shift. 

Discharge measurements. Made from cable just above the gage or by wading. 

Diversions. A small but undetermined amount of water is used for irrigation along

the stream. 

Winter flow. Affected by ice during severe winters. Ice jams form occasionally

above the station. 

Accuracy. Results good except at extreme low stages or at times when gage

heights are affected by ice.

certain times and cause backwater at gage. 

Discharge measurements. Made from a suspension footbridge just below the

gage, or, when stage will permit, by wading. 

Winter flow. Not seriously affected by ice. 

Diversions. Small ranch ditches divert water from the stream. 

Accuracy. Bating curves fairly well denned; results fairly reliable.

LOST OEEEK NEAR TAMARACK, IDAHO.

Location. In sec. 28, T. 19 N., R. 1 W. Boise meridian, about one-fourth mile below 

the dam of the Lost Valley reservoir, 6 miles southwest of Tamarack post office, 

and 20 miles north of Council.

Records available. Gage-height records obtained at the gaging station only for part 

of 1911, but total run-off for 1910 and 1911 has been computed from data furnished 

by the Weiser Valley Land & Water Co. The tables of total run-off are published 

herewith in addition to the data obtained directly at the gaging station.
400 SURFACE WATER SUPPLY, 1911, PART XII.

Drainage area. 30 square miles.

Gage. Vertical staff on left bank.

Channel. Rough; bed of stream is rock; banks high and sparsely covered with 

willow bushes; one channel at all stages.

Diversions and storage. No diversions between dam and station. Available 

capacity of reservoir at the present elevation of the spillway is reported by the 

company to be 13,000 acre-feet.

Accuracy. Daily discharge for 1911 represents the mean of two current-meter measurements each day. Estimates of run-off for 1910 and 1911 probably reasonably 

accurate.

Cooperation. Records and estimates are based on data furnished by Swendsen, 

Swendsen & Pierce, engineers for the Weiser Valley Land & Water Co. Data for 

1911 were collected by Lynn Crandall, junior engineer United States Geological 

Survey, on furlough and employed by the above firm.

NOTE. Records for Jan. 1 to June 30,1910, and Jan. 1 to June 23,1911, show amount of water passing the 

gaging station below the dam. Records for July 1 to Dec. 31 each year represent the inflow into the reservoir determined from monthly estimates based on measurements of inflow and knowledge of local conditions. On May 22,1910, the gates were partly and on July 1,1910, entirely closed. In 1911 the gates were 

closed June 24. The water stored estimated by Swendsen, Swendsen & Pierce as 12,500 acre-feet for 1910 

and 11,000 acre-feet for 1911 was released between July 1 and Dec. 31 each year, and passed the gaging 

station in addition to the amounts shown in above tables for July to December. The tabulated yearly 

values include the amounts stored and released.

COLUMBIA RIVER BASIN. 411

POWDER EIVEE NEAE NOETH POWDER, OEEG.

Location. In the NW. £ sec. 26, T. 6 S., R. 40 E., at proposed dam site for Thief

Valley reservoir, 7 miles east of North Powder and about 8 miles southeast of

Telocasset.

Records available. March 9, 1909, to September 30, 1911. 

Drainage area. 826 square miles. 

Gage. Inclined and vertical staff. 

Channel. Bowlders and gravel; practically permanent. 

Discharge measurements. Made from cable and car at gage section. 

Winter flow. River freezes; gage heights may be affected two or three months. 

Artificial control. Temporary dam constructed each year about 1 mile above the

station to subirrigate adjoining lands. May cause some fluctuation during the

low-water periods. 

Diversions. Most of the low-water flow of Powder River and tributaries is diverted

above this point for irrigation. 

Accuracy. Results good, except during the winter, when as a rule no estimates can

be made. 

Cooperation. Gage readings furnished in part by the Powder Land & Irrigation

Co.

No discharge measurements made during the year.

Daily gage height, in feet, of Powder River near North Powder, Oreg., for the year ending

Sept. SO, 1911.

and 2J miles by trail northeast of the Basin mine, 35 miles northeast of Baker.

Records available. July 24 to September 2, 1911. With the addition of West 

Fork records at the station give the same results as the station below, which was 

maintained May 20 to September 29, 1909, March 1 to September 10, 1910, and 

June 21 to July 23, 1911. Records at the lower station for 1911 are of no value 

on account of unfavorable conditions.

Drainage area. Not measured.

Gage.- Vertical staff.

Channel. Rocky; practically permanent.

Discharge measurements. Made from cable and car, or by wading. Conditions 

at cable unfavorable for accurate measurements.

Winter flow. Probably affected by ice.

Diversions. Sparta ditch diverts some water above station.

Cooperation. Gage readings furnished by Powder Land & Irrigation Co.

SALMON RIVER NEAR PIERSON, IDAHO.

Location. In sec. 1 (approximate), T. 8 N., R. 13 E. Boise meridian, at George 

Achen's ranch, about 4J miles below Pierson post office. Fourth of July Creek 

enters about one-half mile above the station and Lake Creek (outlet to Redfish 

Lakes) about 12 miles below.

Records available. December 23, 1910, to June 4, 1911.

Drainage area. Not measured.

Gage. Originally a vertical staff on right bank, opposite a lone pine tree on the 

left bank about 300 yards from Achen's house. June 5, 1911, this gage was 

washed out and was replaced on August 4 by a sloping gage at same point. Readings on the new gage were begun September 24. Relation of the new datum to 

the old not definitely known.

Channel. Coarse gravel; should be permanent.

Discharge measurements. Made from a cable and car or, during low stages, by 

wading.

Winter flow. Ice exists along the shores of the stream, but the gage heights are 

not believed to be seriously affected thereby.

Diversions. No diversions from the river in this vicinity.

Accuracy. Reliable estimates from records on old gage are impossible because of 

lack of discharge measurements referred to that gage.

about one-half mile below the present gage at the present site of the cable and 

auxiliary gage. Relation between the first and second gages not determined.

Channel. Gravel; probably shifting. Two channels at present gage during extreme 

high water.

Discharge measurements. Made from a bridge at Benner's ranch, from the cable, 

or by wading.

Diversions. No important diversions above the station.

Winter flow. Affected by ice to some extent.

Accuracy. No measurements referred to the first gage and no estimates possible for 

December 21 to May 5. Results from records on the second gage are believed 

to be good.

PAHSIMEROI RIVER NEAR GOLDBURG, IDAHO.

Location. In sec. 19, T. 11 N., R. 24 E. Boise meridian, near a large dead tree 

standing on the left bank; about three-fourths of a mile northwest of McJilton's 

house, about 10 miles southwest of Goldburg post office, and about 1 mile above 

the mouth of Burnt Creek.

Records available. January 30, 1910, to September 30, 1911.

Gage. On April 12, 1910, a new vertical staff gage was installed on the right bank 

about 30 feet below the old one which was at the dead tree. Gage heights prior 

to April 12 have been referred to the new gage by comparative readings.

Channel. Gravel, and probably permanent.

Discharge measurements. By wading or, when'necessary, from a cable.

Winter flow. Ice forms in winter months from 2 to 5 feet thick and flow decreases 

at times to practically nothing.

Diversions. Wells ditch diverts water about 4 miles below the station and carries 

it over a low divide into Goldburg Creek.

Accuracy. Rating curve well defined; open-channel records are reliable.

BIG CREEK NEAR PATTERSON, IDAHO.

Location. On unsurveyed land approximately in sec. 18, T. 13 N., R. 24 E. Boise 

meridian, at the mouth of the canyon and directly down the hill from Carey's 

mine, about 8 miles north of Goldburg post office and about 6 miles southeast 

of Patterson; below all important tributaries.

Records available. January 28, 1910, to September 30, 1911.

Gage. Vertical staff on left bank.

Channel. Rocky; should be permanent.

Discharge measurements. Made from a footbridge at high stages and by wading 

at low water.

Winter flow. Affected slightly by ice.

Diversions. A large part of the flow sinks or is used for irrigation before reaching 

Pahsimeroi River. A diversion is proposed just below the station to carry the 

water into a proposed reservoir on Goldburg Creek.

Accuracy. Rating curve fairly well defined; records reliable.

GRANDE RONDE RIVER AT HILGARD, OREG.

Location. In sec. 32, T. 2 S., R. 37 E., about half a mile east of Hilgard, just 

below Five Point Creek, at the county highway bridge, about 8 miles above 

head of Grande Ronde Valley.

Records available. November 6,1903, to March 3,191Q; October 1,1910, to October 

5, 1911.

Drainage area. 660 square miles.

Gage. Vertical staff nailed to bridge abutment. Originally gage was attached to 

left abutment; old gage and bench mark were destroyed in 1910. Readings 

after October 1, 1910, made from a gage attached to right abutment and having 

no determined relation to the earlier gage.

Channel. Sand and gravel. Probably permanent. One channel at all stages. 

Log driving formerly affected gage heights about two months in early summer, 

but no logs driven past station in 1911.

Discharge measurements. Made from bridge or by wading.

Winter flow. Severe ice conditions obtain for one or two months each winter.

Artificial control. Practically no diversion and no storage above station.

Accuracy. Results for 1910-11 good; those for previous years poor because of obstruction by logs and unfavorable conditions.

The following discharge measurement was made by E. A. Porter: 

March 22, 1911: Gage height, 3.80 feet; discharge, 1,190 second-feet.

WALLOWA EIVEE AT MINAM, OEEG.

Location. In sec. 29, T. 2 N., R. 41 E., 1,000 feet below the new county highway 

bridge at Minam and about the same distance below the mouth of Minam River; 

12 miles from Elgin and 9 miles below Wallowa Valley.

Records available. November 18, 1903, to September 28, 1907; November 16, 1908, 

to September 30, 1911.

Drainage area. 570 square miles.

Gage. Two sections on left bank at Bite of old highway bridge, which collapsed 

in October, 1905.

Channel. Clean gravel; practically permanent. Banks will not overflow; one channel at all stages.

Discharge measurements. Made from highway bridge.

Winter flow. Materially affected by ice and ice jams during severe winter weather.

Diversions. Many ditches divert from Wallowa River and its western tributaries 

for irrigation in the Wallowa Valley, above the station.

Accuracy. Results are good, except during ice periods and extreme high water; 

no measurements have been made at extreme high stages.

No discharge measurements were made during the year.

Daily gage height, in feet, of Wallowa River near Minam, Oreg., for the year ending Sept.

30, 1911.

NOTE. Discharge, excepfras noted below, determined from two fairly well defined rating curves, one 

applicable to gage heights for 1910, the other to heights for 1911. Discharge Jan. 1 to 7 estimated because 

of ice. Discharges interpolated for days in December and September for which gage heights are missing. 

Discharge estimated from hydrograph comparisons with record of stations at Grangeville and Kamftah for 

the following periods for which the gage height records are probably unreliable: Mar. 29 to 31, as given in 

table; Apr. 1 to 20, mean discharge 1,250 second-feet; Apr. 21 to 28, 2,400 second-feet; May 19 to 31, 2,700 

second-feet; June 1 to 8, 3,000 second-feet.

COLUMBIA EIVER BASIN. 459

UMATILLA RIVER AT YOAKUM, OREG.

Location. In sec. 2, T. 2 N., R. 30 E., at the Yoakum wagon bridge, 18 miles below

Pendleton and half a mile east of the Yoakum station on the Oregon-Washington

Railroad & Navigation Co.'s line.

Records available. May 5, 1903, to September 30, 1911. 

Drainage area. 1,200 square miles. 

Gage. Vertical staff spiked to right abutment of highway bridge; datum has remained

unchanged. 

Channel. Gravel; shifts in extreme floods. One channel at all stages. Left bank

overflows during extreme floods. Control composed of lava bowlders. 

Discharge measurements. Made from upstream side of highway bridge or at low

water by wading.

Winter now. River occasionally freezes for short periods. 

Artificial control. Summer flow affected by diversions for irrigation and by. the

release of stored water from the Furnish reservoir, 5 miles upstream. 

Accuracy. Results good; low-water records for 1911 uncertain on account of lack of

measurements.

Cooperation. Station maintained by the United States Reclamation Service. 

No discharge measurements made during the year.

Daily gage height, in feet, of Umatilla River at Yoakum, Or eg., for the year ending Sept.

30, 1911.

COLUMBIA RIVER BASIN. 461

UMATILLA RIVER NEAR UMATILLA, OREG.

Location. In sec. 21, T. 5 N., R. 28 E., 1£ miles above TTmatilla and the mouth 

of the river, near main line of Oregon-Washington Railroad & Navigation Co., 

one-fourth mile below diversion point of Oregon Land & Water Co.'s canal.

Records available. October 21, 1903, to September 30, 1911. Records show the 

total unappropriated flow of the river.

Drainage area. 2,130 square miles.

Gage. Inclined staff in two sections.

Channel. Solid rock without gravel or sand. One channel at all stages.

Discharge measurements. Made from cable and car.

Winter flow. Occasionally shore or floating ice; no material effect.

Diversions. Large part of total flow of river diverted for irrigation above station. 

The TTmatilla project feed canal also diverts water during the winter for storage 

in the Cold Springs reservoir. The low-wafer flow is return water from the 

Hermiston project.

Accuracy. Results excellent.

The following discharge measurement was made by Charles Leidl: 

September 20, 1911: Gage height, 2.40 feet; discharge, 73.8 second-feet.

Daily gage height, in feet, of Umatilla River near Umatilla, Or eg., for the year ending

Sept. 30, 1911.

DESCHUTES RIVER AT BENHAM FALLS, NEAR BEND, OREG.

Location. In the NE. \ sec. 16, T. 19 S., R. 11 E., about 250 yards above Benham 

Falls, and 14 miles above Bend; above the more important irrigation diversions 

from Deschutes River, and just below the dam site of the proposed Benham Falls 

reservoir.
COLUMBIA RIVER BASIN. 477

Records available. March 30,1909, to September 30,1911. Records at this station

are directly comparable with those at West's ranch, 7 miles upstream by river,

July 21, 1906, to February 203 1909. 

Drainage area. Indeterminate. 

Gage. Vertical staff driven into edge of stream on right bank. Maintenance of gage

datum at times somewhat uncertain. 

Channel. Sandy; may shift slightly. Considerable growth of weeds along the

right bank.

Discharge measurements. Made from car and cable. 

Winter flow. Not materially affected by ice. 

Diversions. The diversion of water by some small ditches that are taken out above

this station has no appreciable effect on discharge. 

Accuracy. Rating curve well denned. Some uncertainty as to effect of weeds. As

this record has been used as basis for all studies of the possibilities of power and

irrigation development on Deschutes River between West Fork and Crooked and

Metolius rivers, it has been extended by the aid of the records at Bend and West's

ranch from January 1, 1905, to September 30, 1911. 

Cooperation. Station maintained in cooperation with the Central Oregon Irrigation

Co.

COLUMBIA EIVEB BASIN. 481

CENTRAL OREGON CANAL NEAR BEND, OREG.

Location. In sec. 7, T. 18 S., R. 12 E. at a flume section 1 mile below the point

where the waters in the main diversion canal are divided between this canal and

the Pilot Butte canal; about 2 miles south from Bend, Oreg. 

Records available. May 11, 1905, to September 30, 1911. 

Gage. Vertical staff, consisting of a painted strip of galvanized iron nailed to the

inside of flume on right side. 

Channel. A plank flume of rectangular cross section provided with battened seams.

Flume rather unstable, but the rating appears not to change. 

Discharge measurements. Hade from yoke of flume at gage section. 

Winter flow. Canal operated almost continuously. The flow in winter is small in

volume. The fall through the section at the gage is sufficient to maintain open

channel at all times. 

Accuracy. Records accurate. Earlier records of discharge of over 100 second-feet

subject to revision on account of inaccurate method of measurement. 

Cooperation. Station maintained in cooperation with the Central Oregon Irrigation

Co.

The following discharge measurement was made by R. W. Davenport: 

May 17, 1911: Gage height, 2.40 feet; discharge, 200 second-feet.

Daily gage height, in feet, of Central Oregon canal near Bend, Oreg., for the year ending

Sept. 30, 1911.

COLUMBIA EIVEE BASIN. 489

DESCHUTES RIVER AT MOODY, NEAR BIGGS, OREG.

Location. In the SE. \ sec. 26, T. 2 N., E. 15 E., 1 mile below Moody railroad station, 

li miles above the bridge of the Oregon-Washington Eailroad & Navigation Co., 

about 5 miles southwest of Biggs, Oreg., and 1J mijes above the mouth of the river.

Records available. July 7, 1906, to September 30, 1911; October 19, 1897, to 

December 31,1899, for a station near Moro, 10 miles above the mouth of the river, 

in the NE. i sec. 5, T. 1 S., E. 16 E. Eecords for 1908 and 1910 soiriewhat fragmentary.

Drainage area. About 9,180 square miles.

Gage. Staff in two sections the lower inclined, the upper vertical. At Moro station, 

gage was an inclined staff.

Discharge measurements. Made from a cable about 450 feet above the gage. At 

Moro station made from the "free bridge," 3 miles below the gage.

Diversions. Summer discharge at this station has been progressively reduced since 

about 1904 or 1905 by diversions from the upper river. Some of this water returns, 

but the net reduction during midsummer is now probably 10 or 15 per cent.

Accuracy. Eating curve excellent. Eecords good except for periods during which 

the gage-height record is fragmentary and for which discharge has been estimated 

from studies of*the records.

Cooperation. Gage heights furnished by M. A. Moody, The Dalles, Oreg.

No discharge measurements made during the year.

Daily gage height, in feet, of Deschutes River at Moody, near Biggs,-Oreg., for the year

ending Sept. 30, 1911.

TUMALO CREEK NEAR BEND, OREG.

Location. In the SE. \ sec. 23, T. 17 S., R. 11 E.,half a mile below highway bridge

on Bend-Sisters road, "4 miles above mouth. 

Records available. October 6, 1906, to February 23, 1911 (fragmentary). This

station is maintained in winter months to insure a year-long record on the stream

The upper station is somewhat isolated and sometimes inaccessible in winter. 

Drainage area. 57 square miles. 

Gage. Vertical staff, nailed to overhanging stump, since November, 1910; previous

records at different site. 

Channel. Rocks and gravel; not liable to shift greatly.
502 StrEPACE WATlB SUPPLY, 1911, PAR5? Xfi.

Discharge measurements. At ordinary stages made by wading near the gage; at 

flood stages, from the highway bridge, half a mile above gage.

Winter flow. Gage heights have been considerably affected during extreme cold 

weather.

Diversions. All the water of this stream diverted above station during the irrigation season, making it dry except for seepage return.

Accuracy. An accurate open-channel curve has been developed, applicable except 

during extreme high water.

The following discharge measurement was made by B. W. Davenport: 

November 15, 1910: Gage height, 1.44 feet; discharge, 77 second-feet.

Daily gage height, infect, and discharge, in second-feet, of Tumalo Creek near Send, Oreg., 

for the year ending Sept. SO, 1911.

SQUAW CEEEK NEAR SISTERS, OREG.

Location. In sec. 30, T. 15 S., B. 10 E., about 4 miles above Sisters and above all

diversions except McAllister's ditch. 

Records available. July 1, 1906, to September 30, 1911. 

Drainage area. 63 square miles. 

Gage. Vertical staff. 

Channel. Gravel and rock; practically permanent. Backwater from a changeable

dam reaches the gage and introduces changes in the rating curve. 

Discharge measurements. Made from a foot log just above the gage.
COLTJMBIA RIVER BASIN. 5oa

Winter flow. Ice tends to jam above the dam, and during extreme cold weather 

the effect is very marked.

Diversions. McAllister's ditch heads above this station and its flow is added to 

get the total. The low-water flow of the stream is all diverted by several irrigation ditches below the station.

Accuracy. Records for 1910-11 are good; those for previous years are subject to 

considerable error.

McALLISTER'S DITCH NEAR SISTERS,

Location. About 100 yards below intake, in the SW. £ sec. 30, T. 15 S., R. 10 E.,

above first spillway. 

Records available. May 2 to November 22, 1909; June 29, 1910, to September 30,

1911.

Gage. Vertical staff in side of ditch. 

Channel. Earth section of canal.

Discharge measurements. From crosspiece of waste gate or by wading. 

Winter flow. Water shut off in freezing weather. 

Accuracy. Results 1909-1911 are subject to much uncertainty because of infrequent

measurements and changes in conditions. Gage heights also were liable to be

affected by changes in the wasteway just below the station.

Discharge measurements of Me Allister's ditch near Sisters, Oreg., in the year ending Sept.

NOTE. Discharge determined from a poorly defined rating curve. These discharges have been added 

to those at Squaw Creek station to give total flow. Discharge estimated Dec. 19 to 28; ditch frozen over. 

Water turned out of ditch Jan. 15 to March 8.
COLtrMBIA RiVER BASIN. 507

CROOKED RIVER NEAR POST, ORECL

Location. In sec. 7, T. 17 S., E. 21 E., 12 miles above Post, and half a mile below

mouth, of North Fork of Crooked Eiver, at a point locally known as Stewart's

Grade, just below dam site of proposed reservoir. 

Records available. November 9, 1909, to August 27, 1911. 

Drainage area. 1,390 square miles. 

Gage. Combination vertical staff and inclined staff. Vertical staff read at low water;

datum lowered 1 foot October 22, 1909; all gage heights for 1909 reduced to new

datum.

Channel. Eocks and bowlders; probably permanent.

Discharge measurements. Made from cable and car at gage section;, very poor. 

Winter flow. Stream freezes and water sometimes flows over ice; gage height

affected for two or three months each winter. Estimates of discharge during such

periods have generally been made by comparison with records of Prineville

station. 

Diversions. A considerable and unknown amount of water is diverted for irrigation

above the station. 

Accuracy. Eesults only fair on account of unfavorable conditions.

WHITE RIVER NEAR TYGH VALLEY, OREG.

Location. In sec. 10, T. 4 S., iff 13 E., 1 mile south of Tygh Valley, 1 mile above 

mouth of Tygh Creek, and 4 miles above the White River Falls development of 

Pacific Power & Light Co.

Records available. June 18 to September 30, 1911.
COLUMBIA RIVER BASIN. 519

Drainage area. Not measured.

Gage. Vertical staff on lower corner of left pier of highway bridge.

Channel. Gravel and sand; shifting. White River carries a heavy load of glacial

sediment at times.

Discharge measurements. Made from lower side of highway bridge. 

Winter flow. Affected by ice; ice jams occasionally form during extremely cold

weather. 

Diversions. Probably no diversion from White River above the station, although

diversion of water for irrigation lands south of lower White River is probably

feasible. 

Accuracy. Results good during low water, but somewhat uncertain at other times,

as not enough measurements have been made to determine possible shifts.

NOTE. Discharge determined from two fairlywell defined rating curves. Discharge figures for Oct. 1 

to Dec. 31, 1910, supersede those published in Water-Supply Paper 292, p. 557. Some water was diverted by the Eugene power canal from Februaiy to May, but the amount was probably a very small 

percentage of the total flow of the river.

entirely on the accuracy of the gage heights, which represent only approximately the daily mean on account of fluctuations caused by the operation of 

the power plant above.

Cooperation. Gage-height record furnished by N. L. S. Lauryy, of Estacada, Oreg.

The following discharge measurement was made by R. W. Davenport: 

September 12,1911: Gage height, 3.95 feet; discharge, 1,100 second-feet.

i Incorrectly published as 668 square miles in 1909 and 1910 reports.
