the following item and appropriations:

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

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

Annual appropriations for the fiscal years ending June SO, 1895-1914.

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

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

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

1911 to 1914, inclusive........................................... 150,000

In the execution of the work many private and State organizations 

have cooperated, either by furnishing data or by assisting financially 

in collecting the data. Acknowledgments for cooperation of the 

first kind are made in connection with the description of each station 

affected and of the second kind on pages 10 and 11.

Measurements of stream flow have been made at about 2,000 points 

in the TJ'nited States and also at many points in small areas in Seward 

Peninfula and the Yukon-Tanana region, Alaska, and in the Hawaiian 

Islands. During 1912 gaging stations were maintained by the

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

and many discharge measurements were made at other points. In 

connection with this work data were also collected in regard to 

precipitation, evaporation, storage reservoirs, river profiles, and 

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

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

PUBLICATIONS-

«

A report for each year has been prepared embodying the streamflow data collected during that year. An index to the reports containing stream-flow measurements prior to 1904 has been published 

as Water-Supply Paper 119. Circulars are also available giving 

complete lists of the gaging stations maintained by the Survey to 

date and a list of the reports relating to the water supply of the 

country.

Prior to 1901 gage heights and discharge measurements were 

published in water-supply papers or bulletins and .estimates of 

monthly discharge in annual reports; since 1901 both classes of 

data have been published in water-supply papers, and they are 

now being published in 12 parts, as shown in the following table:

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

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

to 1912. The data for any particular station will be found in the 

reports covering the years during which the station was maintained. 

For example, data for any station in the area covered by Part I 

are published in Water-Supply Papers 97, 124, 165, 201, 241, 261, 

281, 301, and 321, which contain records for the New England 

streams from 1903 to 1912. The year covered by the report is indicated at the head of the column in which the paper is listed.
6 SURFACE WATER SUPPLY, 1912, PART XII.

"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 the drainage 

area would be covered if all the water flowing from it in a given 

period were conserved and uniformly distributed on the surface. 

It is used for comparing run-off with rainfall, which is usually expressed in depth in inches.

An "acre-foot" is equivalent to 43,560 cubic feet and 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 work.

CONVENIENT EQUIVALENTS.

EXPLANATION OF DATA.

For each regular gaging station the following data are given so far as 

available: Description of the station, list of discharge measurements, 

table of daily gage heights, table of daily discharges, 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 equipment 

of gaging stations, the descriptions give information in regard to
8 SURFACE WATER SUPPLY, 1912, PART XH.

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 regarding the accuracy of the data.

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

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

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

given hi 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 hi 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. lu general, the zero is 

located somewhat below the lowest known flow, so that nggative readings shall not occur.

The discharge measurements and gage heights are the base data 

from which rating tables, daily discharge tables, and monthly discharge tables are computed.

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 by plotting gage heights in 

feet as ordinates and discharge hi second-feet as abscissas.

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

corresponding to the 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 pages 5-6, are based.

The base data presented in this report, unless otherwise stated in 

description of station, have been collected by the methods commonly 

used at current-meter gaging stations and described in standard textbooks.

ACCURACY OF FIELD DATA. 9

Plate I shows typical gaging stations. Plate II shows the current 

meter used in the work.

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 

curves 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 also 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
10 SURFACE WATEE SUPPLY, 1912, PART XH.

the variation in the flow by which the period of deficiency may be 

determined.

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.

During the year ending September 30, 1912, the work in Montana, Oregon, Idaho, and Washington has been done under cooperative agreements between the United States Geological Survey and 

the States.

The United States Reclamation Service, the OfiB.ce of Indian 

Affairs, the Forest Service, and the Weather Bureau also cooperated 

with the Survey hi the collection of records.

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.

In general, the cooperative agreements specify that the United 

States Geological Survey shall allot 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.

Special acknowledgments are due to A. W. Mahon, State engineer 

of Montana, to A. E. Robinson, State engineer of Idaho, to John H. 

Lewis, State engineer of Oregon, and to Henry Landes, State geologist of Washington, for the very efficient manner in which they 

represented their States in the cooperative investigations.
DIVISION OF WOEK. 11

Acknowledgments are also due to the engineers and employees of 

the United States Reclamation Service, the United States Forest 

Service, and the United States Office of Indian Affairs for assistance, 

suggestions, and the freest use of data gathered exclusively for them 

and paid for by them. Acknowledgments are also due to the Corps 

of Engineers, United States Army, and to the officers of the United 

States Weather Bureau for hydrographic and climatologic data.

below an overhanging chain gage on right bank about 150 feet below the ferry

cable; automatic gage set to datum of chain gage. 

Channel. Practically permanent. 

Discharge measurements. Made from ferry cable. 

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

open at control section below gage. Relation between gage height and discharge

little 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.

Discharge measurements of Clark Fork near Plains, Mont., in the year ending Sept. SO,

1912.

RACETRACK CREEK NEAR ANACONDA, MONT.

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

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

Records available. July 11 to October 31,1911; January 19 to September 30,1912.

Drainage area. 38 square miles.

Gage. Chain, fastened to posts on left bank, installed June 18, 1912. Previous 

to that date a vertical staff fastened to a tree and ledge rock on left bank, about 

300 feet downstream, was used. New gage is referred to different datum.

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

Discharge nfeasurements. Made by wading.

Winter flow. 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 good at new gage. Gage heights on old gage were 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.

Discharge measurements of Racetrack Creek near Anaconda, Mont., in 1912.

NOTE. Discharge, Oct. 1 to Dec. 31, determined from a rating curve well denned between 1,100 and 

8,000 second-feet and fairly well denned outside those limits. Discharge, Jan. 1 to Sept. 30,1912, determined 

from a rating curve well denned between 400 and 8,000 second-feet; above 1,880 second-feet it coincides 

with the previous curve. Mean discharge estimated at 400 second-feet Jan. 3-26. Discharge interpolated 

Sept. 8-12.

during April, 1912, affected the discharge relation.

Discharge measurements. Made by wading 200 feet below the bridge or, during 

very high water, from the bridge.

Winter flow. Seriously affected by ice.

Diversion. None.

Accuracy. Results fair.

NOTE. Discharge determined from two fairly well defined rating curves, one used before the construction 

of the pipe-line trestle in April, 1912, and the other afterwards.

PRIEST RIVER AT OUTLET OF PRIEST LAKE, AT COOLIN, IDAHO.

Location. In the SE. \ sec. 9, T. 59 N., R. 4 W., in Priest Lake, at Coolin, Idaho, 

about 2 miles from the outlet.

Records available. June 18 to September 8, 1911; March 2 to April 5, 1912 (fragmentary); July 13 to September 30, 1912.

Drainage area. 572 square miles.

Gage. Vertical staff, attached to piles at wharf at Coolin. The original gage used 

June 18, 1911, to April 5, 1912, had no determined relation to that used after 

July 12, 1912.

Channel. Channel at the outlet has rocky bed and high banks; probably permanent.

Winter flow. The lake is usually frozen over from January 1 to April 15.

Accuracy. It is proposed to determine the relation between the stage of the lake 

and the discharge at the outlet. The relation will probably be affected by ice 

and wind on the lake.

Cooperation. Gage-height record furnished by the United States Forest Service.

NOTE. Gage heights Dec. 22-26, 1911, probably affected by ice. All gage heights during 1912 were 

more or less affected by log jams. This effect is believed to have been very marked during the spring 

months and from Sept. 22-27,1912. Gage heights in January, February, and possibly part of March were 

probably also somewhat affected by ice.

NOTE. Discharge determined as follows: Oct. 1-14,1911. by indirect methods for shifting channels; Oct. 

15 to Dec. 21,1911, from a fairly well denned rating curve; Dec. 22-31,1911, estimated; May 1-15,1912, from 

a curve through the measurement made May 13; May 16-20, by shifting-channel methods; May 21 to Nov. 

20, from a fairly well defined curve, excepting the period Sept. 22-27, which was interpolated. No estimate 

attempted Jan. 14 to Apr. 30,1912, because of unknown effect of log jams and ice.

SNAKE EIVER 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, 1912.

Drainage area. Not measured.

Gage. Vertical staff on left bank.

Channel. Channel under the cable shifts, but the Anderson dam controls the relation 

of gage height to discharge. This relation has been affected at times by repair 

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

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

Winter now. Seriously affected by ice.

Regulation. Records affected by storage in Jackson Lake.

Diversions. A small ditch diverts around the station, but its maximum capacity ig 

probably not 20 second-feet.

Accuracy. Results good.

296 SURFACE WATER SUPPLY, 1912, PART XII.

SNAKE RIVER AT MILNER, IDAHO.

Location. In sec. 29, T. 10 S., E. 21 E. Boise meridian, about 300 yards below the

dam at Milner.

Records available. May 10, 1909, to September 30, 1912. 

Drainage area. Not measured. 

Gage. Staff in two sections; lower section inclined, upper vertical. During extreme

low water a temporary station is maintained about 300 feet below the regular

station.

Channel. Lava rock; practically permanent. 

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

planks at the temporary gage. 

Winter flow. Not materially affected by ice.

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 5^ miles above the mouth of the river.

Records available. September 1, 1909, to September 30, 1912; 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.
SNAKE EIVEE BASIN. 309

Gage. Inclined staff on left bank reading from 334 to 354.8 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 of a 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. Eating curve well defined between 20,000 and 240,000 second-feet.'

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

The following discharge measurement was made by Charles Leidl: 

February 24, 1912: Gage height, 38.6 feet; discharge, 47,000 second-feet.

Daily gage height, in feet, of Snake River near Burbank, Wash., for the year ending Sept.

30, 1912.

FORT HALL LOWER CANAL NEAR BLACKFOOT, IDAHO.

Location. In sec. 15, T. 3 S., R. 35 E. Boise meridian, about half a mile below the

head gates and 2J miles southeast of Blackfoot. 

Records available. May 15 to September 30, 1912. 

Gage. Bristol automatic gage referred to a vertical staff gage. 

Channel. Concrete-lined rating flume. Growth of moss and weeds in canal below

rating flume affects the relation of gage height to discharge, and necessitates

frequent measurements.

Discharge measurements. Made from a suspension footbridge a* the gage. 

Accuracy. Results fair.

bank 100 feet below the present gage at different datum. All 1912 readings 

reduced to the datum of the present gage.

Channel. Coarse gravel; practically permanent.

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

Winter flow. Seriously affected by ice; gage height observations suspended during 

the frozen season.

Diversions. Station is above all important diversions. Two small ditches divert 

occasionally between the gage and the cable but their maximum capacity is not 

over 5 second-feet. "

BIG LOST RIVER NEAR MACKAY, IDAHO.

Location. In sec. 18, T. 7 N., R. 24 E. Boise meridian, near the Oleson suspension 

bridge, about three-fourths of a mile below the intake of Sharp ditch, 1J miles 

below the Mackay dam, and 2J miles above Mackay.

Records available. November 12, 1903, to September 1, 1906; May 12 to September 30, 1912.

Drainage area. Not measured.

Gage. Vertical staff on left bank about 50 feet above Oleson's bridge since June 6, 

1912. Between May 12 and June 5, 1912, gages were maintained on each of the 

two channels of the river above Sharp ditch. Records at these two gages gave 

the total flow at the Mackay dam. After June 5 the total flow at the Mackay 

dam is shown by combining the record on Sharp ditch with that on the river 

below the ditch.
328 SURFACE WATER SUPPLY, 1912, PART XH.

Channel. Cobblestones and small bowlders; practically permanent.

Discharge measurements. Made from a cable about 600 feet below the gage,

from the suspension bridge, and by wading. 

Accuracy. Results good.

Location. In sec. 13, T. 15 S., R. 21 E. Boise meridian, about 200 feet above the

upper dam site on Goose Creek, 5 miles above Trapper Creek, and about 10 miles

south of Oakley.

Records available. April 29,1911, to September 30, 1912. 

Drainage area. Not measured. 

Gage. Friez automatic gage referred to vertical staff. On July 30, 1912, conditions

were changed by a flood and after August 22, 1912, records were obtained from

a new gage about 200 feet upstream and at a new datum. The automatic gage

was moved to the new location. 

Channel. Fairly permanent until dtJbris was washed in from a gully below on July

30, 1912. The channel at the new station is rocky and should be permanent. 

Discharge measurements. Made from a cable at the old gage location, or by

wading when stage will permit. 

Winter flow. Affected by ice. 

Accuracy. Results fair. 

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

Water Co.

412 SURFACE WATER SUPPLY, 1912, PART XH?.

OWYHEE CANAL NEAR OWYHEE, OREG.

Location. In sec. 6, T. 21 S., R. 46 E. Williamette meridian, at Wilson's ranch, 2J 

miles below the head gates of the canal, 5 miles above Owyhee, about 6 miles 

above the Owyhee River bridge, and about 15 miles southwest of Nyssa.

Records available. May to October, 1904; May to September, 1905; October 5, 

1911, to September 30, 1912.

Gage. Inclined staff on right bank at the wagon bridge. The gage used during 

1904-5 was on left bank about a quarter of a mile upstream from present gage.

Channel. Smooth dirt section; shifting at high stages.

Diversions. Two wasteways return surplus water to the river between the gage in 

the canal and the station on Owyhee River. One of these is about a quarter of a 

mile below the present gage. Two small ditches with a combined capacity 

probably not exceeding 3 second-feet divert from the main canal above the present 

station.

Discharge measurements. From the bridge or by wading.

Winter flow. Canal freezes occasionally, but the discharge is generally small during 

the frozen season.

Accuracy. Results fair except during frozen season.

MALHEUR RITER AT RIYERSIDE, OREG. 1

Location. In sec. 22, T. 23 S., R. 37 E., at the county highway bridge about 1,000 

feet below South Fork and half a mile west of Riverside post office.

Records available. January 16, 1909, to September 30, 1912 (fragmentary).

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

defined on available maps.

Gage. Chain gage on downstream side of bridge.

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 irrigation on ranches.

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

somewhat uncertain because of lack of discharge measurements.

POWDER RIVER NEAR NORTH POWDER, OREG.

Location. In the NW. i 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 June 30,1912. 

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.

above this point for irrigation. 

Accuracy. Results good during open season.

The following discharge measurement was made by F. B. Storey: 

August 29, 1912: Gage height, 1.49 feet; discharge, 38.7 second-feet.

WALLOWA LAKE NEAR JOSEPH, OREG.

Location. In sec. 5, T. 3 S., R. 45 E., near outlet of Wallowa Lake, about 1 mile 

above Joseph.

Records available. July 15, 1905, to July 28, 19.06; January 13 to September 30, 

1912.

Lake area. 1,470 acres.

Gage. Vertical staff spiked to shore side of pile supporting boathouse, some distance 

above the dam at the outlet. The gage used in 1905-6 was placed on upstream 

side of the dam at the outlet. Its datum was the floor of the sluiceway. No 

determined relation between the gage used in 1905-6 and that used in 1912.

Storage. Wallowa Lake reservoir is operated for the benefit of four ditches which 

divert between the lake and Joseph. The reservoir is allowed to remain practically empty during the winter and is filled during the flood run-off in May and 

June and emptied during August and September. The usual variation in level 

has been about 6.5 feet.

WALLOWA RIVER AT JOSEPH, OREG.

Location. In sec. 5, T. 3 S., R. 45 E., about 300 feet below tie controlling dam at 

the outlet of Wallowa Lake, 50 feet above footbridge, about half a mile above 

Joseph; above the head gates of four irrigation ditches, the first of which takes 

out 125 feet below the gage.

Records available. November 12, 1903, to September 30, 1912.

Drainage area. 52 square miles.

Gage. Vertical staff bolted to a large bowlder on right bank.

Channel. Bed composed of bowlders; will not shift; banks seldom overflow; current 

swift and velocities uneven across section.

Discharge measurements. Made from footbridge or by wading.

Winter flow. Unaffected by ice on account of proximity to lake outlet.

Artificial control. About 10,000 acre-feet of storage developed in Wallowa Lake; 

additional development possible. Beginning with October, 1911, the monthly 

estimates have been corrected for storage.

Accuracy. Results good.

Discharge measurements of Wallowa River at Joseph, Oreg., during the year ending Sept.

WALLOWA KIVEK AT MINAM, OKEG.

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 Minain 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, 1912. 

Drainage area. 570 square miles. 

Gage. Two sections on left bank at site 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. 

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.

COLUMBIA RIVER AT THE DALLES, OREG.

Location. In sec. 34, T. 2 N., R. 13 E., 2,000 feet below the ferry at The Dalles, 

about 18 miles below Deschutes River, and above Hood and Klickitat rivers.

Records available. 1892-1912 with a few breaks. Gage readings at Cascade Locks, 

20 miles below The Dalles, used to extend record back to 1879.

Drainage area. 237,000 square miles.

Gage. Two gages at The Dalles: The Government or Brooks gage used by the 

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 lock 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 6 feet lower. Elevation of datum 

of Brooks gage, 45.6 feet.

Channel. Rocky and permanent 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.

CENTRAL OREGON CANAL NEAR BEND, OREG.

Location. In sec. 7, T. 18 S., E. 12 E., at a flume section half a 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.
564 SUEFACE WATER SUPPLY, 1912, PAET XII.

Records available. May 11, 1905, to September 30, 1912.

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

inside of flume on right side. 

Channel. A p^ank flume of rectangular cross section with battened seams. Flume

rather unstable but the rating appears not to change. 

Discharge measurements. Made 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 of the gage is sufficient to maintain open

channel at all times. 

Accuracy. Results good. 

Cooperation. Gage-height record furnished by the Central Oregon Irrigation Co.

Discharge measurements of Central Oregon canal near Bend, Or eg., in the year ending

Sept. SO, 1912.

DESCHUTES RIVER AT OLINE FALLS, OREG.

Location. In sec. 13, T. 15 S., R. 12 E., 1J miles southwest of Cline Falls, about

4 miles west of Redmond, and 12 miles below Laidlaw. 

Records available. February 15, 1910, to March 4,1911; February 20 to September

30, 1912. 

Drainage area. Not measured.
570 SURFACE WATER SUPPLY, 3912, PART XII.

Gage. Vertical staff on right bank.

Channel. Sand, gravel, and bowlders; some moss grows on the bottom; somewnat

shifting. 

Discharge measurements. Made from a boat which is operated on a tight wire

stretched across the stream near the gage. 

Winter flow. Not materially affected by ice. 

Diversions. Flow affected by diversions as at Bend and Laidlaw stations. The

decrease in discharge between the two stations is evidently due to seepage of

water into the river bed. 

Accuracy. Results good. 

Cooperation. Gage-height record furnished by I. L. Harader.

LOWER COLUMBIA RIVER BASIN. 575

DESCHUTES RIVER AT MOODY, NEAR BIGGS, OREG.

Location. In the SE. £ sec. 26, T. 2 N., R. 15 E., opposite Moody railroad station, 

1J miles above the bridge of the Oregon-Washington Railroad & Navigation 

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

of the river.

Records available. July 7, 1906, to September 30, 1912; October 19, 1897, to December 31, 1899, for a station near Moro, 10 miles above the mouth of the river, 

in the NE. £ sec. 5, T. 1 S., R. 16 E. Records for 1908 and 1910 somewhat fragmentary.

Drainage area. About 9,180 square miles.

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

station gage was an inclined staff.

Channel. Rock and heavy gravel; slightly shifting during floods.

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 in midsummer is now probably 10 or 15 per cent.

Accuracy. Results good.

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

No discharge measurements made during the year.

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

ending Sept. 30, 1912.

SQUAW CREEK NEAR SISTERS, OREG.

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

diversions except McAllister's ditch.

Records available.-^July 1, 1906, to September 30, 1912.

Drainage area. 63 square miles.

Gage. Vertical staff.

Channel. Gravel and rock. 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.

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. Results good.

MCALLISTEK'S DITCH NEAR SISTERS, OREG.

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

below first spillway.

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

1912.

Gage. Since March. 23, 1912, gage-height observations made by measuring depth 

of water over a plug set at the level of the crest Qf a weir. Prior to 1912 a vertical staff gage in the side of the ditch above the first spillway.

Channel. Control consists of the sharp crest of a 5-foot Cippoletti weir.

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

Winter flow. Water shut off in freezing weather.

Accuracy. Results good.

The following discharge measurement was made by J. E. Stewart: 

August 13,1912: Gage height, 1.34 feet, old gage; 0.48 foot on weir gage; discharge

5.64 second-feet.

Location. In see. 10, T. 4 S., R. 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 18,1911, to September 30,1912. 

Drainage area. Not measured.

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

Channel. Gravel and sand; shifting; White Elver 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 of lands south of lower White River is probably

feasible. 

Accuracy. Results good.

falls which is sometimes obstructed by logs, causing backwater.

Discharge measurements. Made from cable 100 feet below gage.
LOWEE COLUMBIA EIVER BASIN. 631

Regulation. Flow affected at times by operation of splash dam 10 miles upstream. 

Diversions. A few ditches divert for irrigation in Trout Lake Valley.
