SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS

IN WASHINGTON AND UPPER COLUMBIA

RIVER BASIN, 1918.

AUTHORIZATION AND SCOPE OF WORK.

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

measurements of streams in the United States during the year ending 

September 30, 1918.

The data presented in these reports were collected by the United 

States Geological Survey under the following authority contained in 

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

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

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

The work was begun in 1888 in connection with special studies 

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

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

carried the following item and appropriations:

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

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

Annual appropriations for the fiscal years ending June SO, 1895-1919.

2 STTEFAOE WAU^ SUPPLY, 1918, PART XH -A,

Measurements of stream flow have been made at about 4,510 

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

Hawaiian Islands. In July, 1918, 1,180 gaging stations were being* 

maintained by the Survey and the cooperating organizations. Many 

miscellaneous discharge measurements were made j&t other pointy 

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 water-supply papers from time to time.

DEFINITION OF TERMS,

The volume of water lowing in a stream ^km "run-*off" or "discharge" is expressed in various terms, eaeh of which has become 

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

into two groups (1) those that represent a rate of flow, as secondfeet, gallons per mimite, miner's inches, and discharge in second-fee* 

per square mile, and (2) those that represent -the actual quantity 

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

The principal terms used in this series of reports are second-fee^ 

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

may be defined as follows: . :-,

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

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

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

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

unit from which others are computed.

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

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

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

regards time and area.

"Run-off in inches" is the depth to which an area would be covered 

if all the water flowing from it in a given period were uniformly 

distributed on the surface. It is used for comparing EOE-pff with 

rainfall, which is usually expressed in inches.

An "acre-foot," equivalent to 43,560 cubic feet, is the quantity 

required to cover an acre to the depth of 1 foot. The term is commonly used in connection with storage ioi* irrigation.

The following terms not in common use are here defined:

"Stage-discharges relation," an abbreviation for the term "illation 

of gage height to discharge."

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

stream below the gage which tietefmine the stage-discharge 

at the gage. It should be noted that the control may &&* be the 

same section or sections at all stages.

EXPI^ANATION OF DATA.

The data presented in this report cover the year beginning October 

1,1017, and ending SeptemberSO, 1918. At the beginning of Jranuary 

. in most parts of the United States much of the precipitation in the 

preceding three months is stored as ground water, in the form of 

snow or ice, or in ponds, lakes, und swamps, and this- »tored water passes 

off in the streams during the spring break-up. At the end of September, on the other hand, the only stored water avaii&bfe for run-off fa 

possibly a small quantity i& he ground; therefore the run-off for a 

year beginning October l*is practically all derived from precipitation 

witnin that year.

The ba^e* data collected at gaging -stations consist of records of 

stage, measurements of discharge, and general information used to 

supplement the gage heights and discharge measurements in determining the 'daily flow. The records of stage a-te obtained ei^h^r from 

direct readings on a staff gage or from a watemstafe reorder &*t 

gives a continuous record of the fluctuations. Measurements of discharge are made with -a current meter. (See Pis. I, II.) The general methods are outlined in standard textbooks on the measurement 

of river discharge.

From the discharge measurements, rating tables are prepared that 

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

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

monthly, and yearly means of discharge are determined.

The data presented for each gaging station in the area covered %y 

this report comprise a description of the station, a table giving ree1- 

drds of discharge measurements, a table showing the daily discharge 

of the stream, and a table of monthly and yearly discharge and 

run-off.

If the base data are insufficient to determine the daily discharge, 

tables giving daily gage height and records of discharge measurements are published.

The description of the station gives, in addition %o statements 

regarding location and equipment, information in regard to any eon- 

. ditions that may affect the permanence of thest^ge-disehargereiatioii, 

covering tttch subjects as the occurrence of ice, Ae uae &£$&& stream 

fbr log driving, shifting of control, and the cause and effect of ;bacltWater; it gives also information as to diversions that decrease ^e 

flow at the gage; artificial regulation, maxintem and mmilatim re* 

corded stages, and the accuracy of the records.
4 SURFACE WATEK, SUPPLY- 1918, PAET XII A.

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

second-feet corresponding to the mean of the gage heights read each 

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

fluctuation the discharge obtained from the rating table and the 

mean daily gage height may not be the true mean discharge for 

the day. If such stations are equipped with water-stage recorders 

the mean daily discharge is obtained by averaging discharge at 

regular intervals during the day or by using the discharge integrator, 

an intrument operating on the principle of the planimeter and containing as an essential element the rating curve of the station.

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

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

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

indicate correctly the stage when the water surface was at crest 

height and the corresponding discharge was consequently larger than 

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

" Minimum' * the quantity given is the mean flow for the day when 

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

the average flow in cubic feet for each second during the month. On 

this average flow computations recorded in the remaining columns, 

which are defined on page 2 are based.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS.

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

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

of observation of stage, measurements of flow, and interpretation of 

records.

A paragraph in the description of the station gives information 

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

with which the discharge rating curve is denned, (3) refinement of 

gage readings, (4) frequency of gage readings, and (5) methods of 

applying daily gage height to the rating table to obtain the daily discharge. For the rating tables "well defined" indicates, hi general, 

that the rating is probably accurate within 5 per cent; "fairly well 

defined," within 10 per cent; "poorly defined," within 15 to 25 per 

cent. These notes are very general and are based on the plotting of 

the individual measurements with reference to the mean rating curve.

The monthly means for any station may represent with high 

accuracy the quantity of water flowing past the gage, but the figures showing discharge per square mile and depth in inches may 

be subject to gross errors caused by the inclusion of large noncontributing districts in the measured drainage area, by lack of 

information concerning water diverted for irrigation or other use, 

or by inability to interpret the effect of artificial regulation of the
ACCURACY OF FIELD DATA. 5

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

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

appear probable. The computations are also omitted for stations 

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

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

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

be used with caution because of possible inherent sources of error 

not known to the Survey.

The table of monthly discharge gives only a general idea of the 

flow at the station and should not be used for other than preliminary estimates; the table of daily discharge allows more detailed 

study of the variation in flow. It should be borne in mind, however, that the observations in each succeeding year may be expected 

to throw new light on data previously published.

CHANNEL AND CONTROL. Bed composed of bedrock and boulders; apparently permanent. No well-defined control. One channel at all stages. Banks high and 

wooded.

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

11.7 feet at 6 a. m. December 18 (discharge, 18,600 second-feet); minimumstage recorded, 0.48 foot at 8 a. m. September 29 (discharge, 58 second-feet).

ICE. None.

DIVERSIONS . None.

REGULATION . None.

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

8,000 second-feet; extended above. Operation of water-stage recorder satisfactory except as indicated in footnote to table of daily discharge. Daily discharge ascertained by applying to rating table mean daily gage height determined by inspecting recorder graph or, for days of considerable variation in 

stage, by averaging results obtained by applying mean gage heights for shorterintervals. Records excellent except for periods estimated for which they aregood.

COOPERATION. Station maintained in cooperation with Straits Power Co.

LYRE BIVER AT PIEDMONT, WASH.

LOCATION. In NE. i sec. 15, T. 30 N., R. 9 W., 1,300 feet below outlet of Crescent 

Lake and half a mile west oi Piedmont, in Clallam County.

DRAINAGE AREA. 49.5 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 1, 1917, to September 30, 1918.

GAGE. Stevens continuous water-stage recorder on right-bank; referred to inside and 

outside staff gages; inspected by T. F. Rixon.

DISCHARGE MEASUREMENTS. Made by wading or from cable 1,000 ieet above- gage.

-CHANNEL AND CONTROL. Channel composed of bedrock and boulders. Banks medium high and wooded. Control was a series of rapids over bedrock at and below 

gage, until September 25, when construction of railroad trestle 125 feet below 

gage was begun. Material dumped into the stream changed control, .at least 

temporarily.

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

5.91 feet at noon January 4 (discharge, 1,080 second-feet); minimum discharge, 

32 second-feet by meter measurement at noon September 29 (stage-discharge relation affected by backwater from construction of trestle below gage)i

ICE. None.

DIVERSIONS. None.

REGULATION. Flow is very uniform because of natural regulation in Crescent Lake.

ACCURACY. Stage-discharge relation permanent from November 30 to September* 24, 

after which there was backwater from construction of railroad trestle below gage. 

October 15 to November 16, 1917, gage was referred to a datum differing an unknown amount from that used thereafter. Rating curves well denned below 

800 second-feet; extended above. Operation of water-stage recorder satisfactory 

except as indicated in footnote to table of daily discharge. Daily discharge aecer- 

, tained by applying to rating table mean daily gage height determined by inspecting recorder graph. Records excellent after December 22; good prior to that 

date except for estimated periods.

SKOKOMISH RIVER BASIN. 

NORTH FORK OF SKOKOMISH BITER NEAR HOODSPORT, WASH.

LOCATION. In SW. J sec. 5, T. 22 N., R. 4 W., at footbridge on Forest Service trail 

to South Fork of Skokomish River, 4 miles below Lake ushman and 4 miles 

northwest of Hoodsport, in Mason County.

DRAINAGE AREA. 91 square miles (measured on Plate I, Professional Paper 7).

RECORDS AVAILABLE. Aug. 17, 1910, to Sept. 22, 1911, fragmentary; February 1, 

1913, to September 30,1918.

GAGE. Stevens continuous water-stage recorder on left bank just below trail bridge; 

inspected by L. L. Dickmson and Phillip Abbey. Datum raised 5.0 feet September 2,1918. (Vertical staff 25 feet below bridge used 1910-11.)

DISCHARGE MEASUREMENTS. Made from cable about a mile above gage or by wading.

CHANNEL AND CONTROL. Composed of rock and gravel; slightly shifting. Banks 

high, not subject to overflow.

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

19.60 feet at 1 p.m. December 18 (discharge, 9,580 second-feet); minimum stage, 

from recorder, 0.77 foot September 28 (discharge, 89 second-feet).

1913-1918: Maximum stage estimated at 23.5 feet January 6, 1914, during part 

of day when recorder was not operating (discharge, estimated, 14,000 second-feet); 

minimum stage recorded in 1918.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. Flow subject to natural regulation at Lake Cushman.

ACCURACY. Stage-discharge relation changed December 18 during high water. 

Drift in stream resulting from forest fire on September 10 caused backwater during 

remainder of year. Rating curves prior to September 10 well defined; curve after 

that date poorly defined. Operation of water-stage recorder excellent except for 

periods indicated in footnote to table of daily discharge. Daily discharge ascertained by applying to rating table mean daily gage height determined by inspecting recorder graph or, for days of considerable variation in stage, by averaging 

results obtained by applying mean gage heights for shorter intervals. Records 

excellent except during period September 10 to 30 for which they are fair.

C OOPERATION . Station maintained in cooperation with city of Tacoma.

PTJTALLUP RIVER AT ALDERTON, WASH.

LOCATION. On township line between sec. 25, T. 20 N., R. 4 E., and sec. 30, T. 20 N., 

E. 5 E., at county bridge No. 78, 1 mile north of Alderton, Pierce County, and 

1J miles above Stuck River.

DRAINAGE AREA. 410 square miles (measured on drainage map published in WaterSupply Paper 313).

RECORDS AVAILABLE. November 20, 1914, to September 30, 1918.

GAGE. Vertical staff in two sections on downstream side of bridge pier on right bank; 

read by Mrs. C. E. Bearney and Mrs. H. D. Foster. Datum of gage lowered 1.00 

foot, August 5, 1918.

DISCHARGE MEASUREMENTS. Made from bridge at gage.

CHANNEL AND CONTROL. Bed composed of silt and gravel; shifting. No well-defined 

control. Right bank is overflowed at gage height about 8 feet; left bank high 

and not subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 12.6 feet at 8 p. m. 

December 18 (discharge, 19,300 second-feet); minimum stage recorded, 0.^3 foot 

at 1.30 p, m. November 17, and 8 a. m. November 19 (discharge, 409 second-feet). 

1915-1918: Maximum stage recorded, December 18, 1917; minimum stage recorded, 1.90 feet December 22 and 24, 1914, September 29-30 and October 12, 

1915 (discharge, 390 second-feet).

ICE. Stage-discharge relation not affected by ice during year.

DIVERSIONS. None.

REGULATION. Operation of the Puget Sound Traction, Light & Power Co.'s plant at 

Electron does not materially affect natural flow, as pondage utilized is small.

ACCURACY. Stage-discharge relation permanent until high water on December 18; 

shifting during remainder of year. Standard rating curve well defined below 

4,000 second-feet and fairly well defined above. Gage read to hundredths twice 

daily during November, July, August, and September, and once daily during 

remainder of year. Slight diurnal fluctuation. Daily discharge ascertained by 

applying daily mean gage height to rating table; shifting-control method used 

December 19 to September 30. Records good.

COOPERATION. Inter-County River Improvement Commission of King and Pierce 

counties furnished gage-height record and made some discharge measurements.

PUYALLTTP BIVER AT PUTALLTJP, WASH.

LOCATION. In sec. 21, T. 20 N., K. 4 E., 1,000 feet upstream from Puget Sound 

Electric Railway bridge, 1 mile north of Puyallup, Pierce County, and 2 miles 

below mouth of Stuck River.

DRAINAGE ABBA. 914 square miles (measured on drainage map published in WaterSupply Paper 313).

EEOOBDS AVAILABLE. May 1, 1914, to September 30, 1918.

GAGE. Stevens continuous water-stage recorder on right bank; inspected by engineers 

of Inter-County River Improvement Commission and of U. S. Geological Survey.

DISOHABGE MEASUBEMENTS. Made from highway bridge three-quarters of a mile 

above gage.

CHANNEL AND CONTBOL. Bed of stream composed of light alluvial silt; shifting at 

all stages. Control formed by section of stream bed extending some distance 

downstream.

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

34.15 feet at 4.45 p. m. December 18 (discharge, 40,500 second-feet); minimum 

stage, 17.36 feet at 8 p. m. November 18 (discharge, 726 second-feet). 

1914-1918: Maximum and minimum stages given above.

ICE. Stage-discharge relation not affected by ice.

DIVEBSIONS. Two hydroelectric plants, owned by Puget Sound Traction, Light & 

Power Co., divert water above station. Water for Electron plant is diverted from 

Puyallup River 10 miles above Electron into equalizing basin having capacity 

of 185 acre-feet; water used at this plant is returned directly to the river. Water 

for Dieringer plant is diverted from White River near Buckley into Lake Tapps 

(capacity, 51,000 acre-feet), and after use is discharged into Stuck River.

REGULATION. See "Diversions."

ACCURACY. Stage-discharge relation changed December 19 to March 10 and April 

20 to May 20; constant at other times. Rating curves well defined below 

30,000 second-feet. Operation of water-stage recorder satisfactory except as 

indicated in footnote to table of daily discharge. Daily discharge ascertained by 

applying to rating table mean daily gage height determined by inspecting recorder 

graph. For period of high water with marked range of stage during December, 

daily discharge was determined by averaging results obtained by applying mean
FUYAULUP EIVEE BASIN, 19

gage heights for shorter intervals. Shifting-control method used December 19 to 

March 10, and April 20 to May 20. Records good.

COOPERATION. Inter-County River Improvement Commission of King and Pierce 

counties furnished gage-height record and made some discharge measurements.

Discharge measurements of Puyallup River at Puyallup, Wash., during the year ending

Sept. SO, 1918.

WHITE BIVEB, AT BUCKLEY, WASH.

LOCATION. In SE. | sec. 34, T. 20 N., R. 6 E., at Northern Pacific Railway bridge

1 mile northeast of Buckley, Pierce County. 

DRAINAGE ABE A. 424 square miles (measured on Plate XI, Water-Supply Paper

313). 

RECORDS AV AH ABLE. April 22, 1899, to August 31, 1903 (gage-height record only

January 1,1902, to August 31, 1903); June 8, 1910, to December 31,1911; January

18, 1913, to September 30, 1918.

 GAGE. Stevens water-stage recorder on left bank 40 feet below railway bridge, installed January 9, 1917; inspected by O. E. Osgood. For description of previous 

gages see Water-Supply Paper 462.

DISCHARGE MEASUREMENTS. Made by wading or from railway bridge.

 CHANNEL AND CONTROL. Bed composed of small boulders and gravel; slightly shifting; gradient steep. No well-defined control. One channel at all stages. Right 

bank low and flat; left bank protected by concrete wing wall.

EXTREMES OP DISCHARGE. Maximum combined daily discharge of river and flume 

during year from water-stage recorder, 18,100 second-feet on December 18; minimum combined daily discharge during year, 349 second-feet November 19.

1899-1903; 1910-1911; 1913-1918; maximum and minimum discharge same as 

above.

ICE. Stage discharge relation not affected by ice.

DIVERSIONS. White River flume diverts water from river half a mile above gage. 

Total monthly discharge is computed from determinations of combined flow of 

river and flume.

ACCURACY. Stage-discharge relation changed at high water on December 18. Rating 

curve used prior to the change fairly well defined throughout; rating curve used 

after the change well defined above 100 second-feet. Daily discharge ascertained 

by applying to rating table mean daily gage height obtained by inspecting gageheight graph or, for days of considerable fluctuation, by averaging results obtained 

by applying the gage heights for shorter intervals. Operation of water-stage 

recorder not satisfactory for several periods. See footnote to table of daily 

discharge. Records good above 100 second-feet except during periods when 

intake was clogged, for which they are fair; below 100 second-feet, poor.

 COOPERATION. Puget Sound Traction, Light & Power Co. furnished gage-height 

record and made some measurements.

WHITE RIVER FLUME AT BTTCEXEY, WASH.

LOCATION. In sec. 35, T. 20 N., R. 6 E., on left side of white River, 800 feet below 

intake, half a mile above Northern Pacific Railway crossing, and 1 mile northeast 

of Buckley, Pierce County.

RECORDS AVAILABLE. January 18, 1913, to September 30, 1918.

GAGE. Stevens long-distance water-stage recorder with transmitter at stilling well 

on right side of flume 800 feet below headgate, and recorder in gate house; installed January 12,1918; inspected by 0. E. Osgood. Prior to January 12, Fuller 

water-stage recorder at stilling well.

DISCHARGE MEASUREMENTS. Made from footbridge at gage.

CHANNEL AND CONTROL. Control formed by long section of flume bottom below gage. 

A rock spill a quarter of a mile below gage is partial control also. Stage-discharge 

relation affected by variable quantity of rocks which work their way from intake 

to rock spill.

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

6.15 feet at 8 a. m. June 7 (discharge, 2,000 second-feet); no flow in flume February 24, May 20-31, and June 1, and 20-28. 

1913-1918: Maximum stage in 1918; flume dry at various times.

ICE. Stage-discharge relation not affected by ice during year.

REGULATION. Gates at intake operated frequently to control flow.

ACCURACT. Stage-discharge relation affected by rocks washed into flume. Four 

well-defined rating curves used respectively, October 9 to December 19, December 20 to June 1, June 2 to September 22, and September 23 to 30. Shiftingcontrol method used October 1 to 8. Operation of water-stage recorder excellent. 

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

determined by inspecting recorder graph or, for days of considerable variation in 

stage, by averaging results obtained by applying mean gage heights for shorter 

intervals. Records excellent.

CEDAR RIVER AT CEDAR FALLS, WASH.

LOCATION. In sec. 4, T. 22 N., R. 8 E., below Seattle municipal power plant atCedar Falls, King County, and 3J miles above Taylor Creek.

DRAINAGE AREA. 83 square miles (measured on topographic maps).

RECORDS AVAILABLE. April 9, 1914, to September 30, 1918.

GAGE. Stevens continuous water-stage recorder on right bank installed April 8,- 

1914, 0.7 mile below power plant; inspected by G. H. Moore.

DISCHARGE MEASUREMENTS. Made from cable 90 feet below gage or by wading.

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

high water. No well-defined control. Banks high. One channel at all stages. 

Stage of zero flow, according to measurements made September 17, 1918, 3.0' 

feet ± 0.2 foot.

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

11.4 feet at 9 a. m. December 19 (discharge, 6,290 second-feet); minimum stagefrom recorder, 3.32 feet at 4 p. m. November 25 (discharge, 0). 

1914-1918: Maximum and minimum stages same as above.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Seattle municipal power plant diverts water direct from Cedar Lakethrough pressure pipe and returns it to river at plant. Practically entire low 

flow is carried through plant.

REGULATION. Flow partly controlled by storage and release of water in Cedar Lake 

reservoir to accommodate requirements of power plant.

ACCURACY. Stage-discharge relation changed December 13. Rating curves welldefined; one used prior to shift not checked by measurement during period. 

Operation of water-stage recorder satisfactory except for periods, December 24-28, 

and July 14-28. Daily discharge ascertained by use of discharge integrator except for periods of defective gage-height record and for periods December 13-23 

and December 29 to January 8, for which mean daily gage heights or mean gage 

heights for shorter intervals were applied to rating table. Records good October 

to December; excellent January to September.

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

by city engineer of Seattle.

reservoir to accommodate requirements of Seattle municipal power plant.

ACCURACY. Stage-discharge relation changed December 13. Rating curve used 

before change well defined; curve used after change well defined below 2,000 

second-feet, but above, based on one discharge measurement at Cedar Falls, and 

estimated intervening inflow. Operation of water-stage recorder satisfactory except as indicated in footnote to table of daily discharge. Daily discharge ascertained by use of discharge integrator except January 4-25 and September 12-16 

and as indicated in footnote to table of daily discharge. Records excellent 

except during periods when recorder was out of order, for which they are good.

STTLTAN RIVEa KEAB StTLTAN, WASH.

LOCATION. In sec. 8, T. 28 N., R. 8 E., at Horseshoe Bend, 4J miles north of Sultan 

and mouth of river, Snohomisli County.

DRAINAGE ABJSA. -Ntrt measured. ' , RECORDS AVAILABLE. August 18,1911, to September 30,1918.

GAGE. Stevens continuous water-stage recorder on left bank a quarter of a mile 

above Horseshoe Bend; inspected by city engineer of Everett. Prior to October 

29, 1915, Lietz water-stage recorder at Camp Habecker 1J miles upstream.

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

CHANNEL AND CONTROL. In .canyon; control formed by large rocks, boulders, and 

heavy gravel; not likely to change except at extremely high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 1&6 feet at about 

9 a. m. December 18 (from high-water mark in well; discharge, 20,600 secondfeet); miniTmiTTi stage from water-stage recorder, 0.61 foot at 7 p. m. September 

29 (discharge, 7? second-feet).

1911-1918: Maximum stage same as above; mininram stage recorded, 4.52 feet 

at Camp Habecker September 29,1915 (discharge, 71 second-feet).

ICE. Stage-discharge relation seldom affected by ice. Water in stilling well freezes 

during very cold weather. No ice during current year.

DIVERSION. None.

REGULATION. None.

ACCURACY. Stage-discharge relation affected by backwater from drift on control 

October 1 to December 13. Drift removed and stage-discharge relation changed 

on December 13 by high water. Rating curve for period October 1 to December 

13 well denned below and poorly defined above 500 second-feet; curve for remainder of year well defined throughout. Operation of water-stage recorder 

satisfactory except for periods indicated in footnote to table of daily discharge. 

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

determined by inspecting recorder graph er, for days of considerable variation in 

stage, by averaging results obtained by applying mean gage heights for shorter 

intervals. Records excellent except for a few days in November and December 

. when amount of backwater effect is uncertain.

COOPERATION. Gage-height record furnished by city engineer of Everett, Wash.

1915; inspected by E. H. Robinson. Prior to August 7,1915, gage was at highway 

bridge 2Jj miled below present site.

DISCHARGE MBASUEBMENTS. Made by wading or from highway bridge at original 

station. : CHANNEL AND CONTROL. Bed composed of large boulders. Control shilte at extremely 

high water. Left bank high; right bank low and heavily wooded. Stage of zero 

, flow, according to measurements made September, 15, 1918, at gage height 0.8 

±0.3 foot. 

EXTREMES op DISCHARGE. Maximum stage recorded during year, 12.16 feet at 10

at 1 p. m. September 30, 1915 (discharge, 146 second-feet).

ICE. Stage-discharge relation not affected by ice. / . DIVERSIONS. None.

REGTJLATION. None.

ACCURACY. Stage-discharge relation changed December 18. Rating curves well 

denned below 7,000 second-feet; extended above. Operation of water-stage 

recorder satisfactory except as indicated in footnote to table of daily discharge. 

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

determined by inspecting recorder graph or, for days of considerable variation 

in stage, by averaging results obtained by applying mean gage heights for shorter 

intervals. Records prior to high water in December, excellent; for periods 

when discharge was estimated, fair; for remainder of year good.

COOPERATION. Puget Sound Traction, Light & Power Co. furnished gage-height 

record and made some discharge measurements.

NORTH FORE OF SNOQtTALMEE RIVER NEAR NORTH BEND, WASH.

LOCATION. In NE. J sec. 26, T. 24 N., R. 8 EM at Gabriel ranch, 2| miles above 

mouth and 3J miles northeast of l^Torth Bend, King County.

DRAINAGE AREA. Approximately 102 square miles (measured on topographic and 

county maps).

RECORDS AVAILABLE. July 4, 1907, to September 30, 1918. All .records prior to 

October 1, 1915, published in Water-Supply Paper 412.

GAGE. Friez water-stage recorder on right bank 200 yards southeast of ranch house, 

installed September 26, 1916; inspected by E. H. Robinson. Previous gages as 

follows: July 21,1907, to September 2,1912, vertical 'staff at highway bridge oneeighth mile above mouth; September 2, 1912, to September 26, 1916, Fuller and 

Friez water-stage recorders at same site and datum.

DISCHARGE MEASUREMENTS. Made by wading or from cable 200 yatds above mouth.

OOANNEL AND CONTROL. Bed composed of boulders and gravel; shifting at extremely 

high stages. No well-defined control. Right bank not subject to overflow; 

left bank fairly high, not subject to overflow except at 'extremely high stages. 

Stage of zero flow, according to measurements made September 14, 1918, gage 

height -0.4 ±0.2 foot.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 10.80 feet at 7.30 

a. m. December 18 (discharge, 9,890 second-feet); minimum stage recorded, 

1.64 feet September 27 (discharge, 76 second-feet).

1907-1918: Maximum stage determined by leveling to high-water mark, 14.5 

feet November 18, 1911 (discharge, 11,100 second-feet); water above gage November 18,19, 23, 24, 29, and 30,1909, and stage may have exceeded that reached 

in 1911. Minimum stage recorded, 1.0 foot September 26-28, 1910 (discharge, 

56 second feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed December 18. Rating curves well 

defined below 4,000 second-feet; extended above. Operation of water-stage 

recorder excellent except as indicated in footnote to table of daily discharge. 

Daily discharge ascertained by applying to rating table the mean daily gage 

height determined by inspecting recorder graph or, for days of considerable

variation in stage, by averaging results obtained by applying mean .gage heights 

for shorter intervals. Partial clogging of intake pipe caused lag of water stage 

in well behind that in river. This caused slight uncertainty in daily records 

for periods of rapidly changing stage, but had little or no effect on monthly records. 

Records good.

COOPERATION. Puget Sound Traction, Light & Power Co. furnished gage-height 

record and made some discharge measurements.

SOUTH FORK OF SBOOTAXJUS WVEH. AT FORTH BBBTD, WASH.

LOCATION. la SE. i sec.' 9, T. 23 N., R. 8 E., at Cooper ranch, half a mile south of 

North Bend, King County, and 3£ miles above mouth.

DRAINAGE A»»A. 84 square miles (measured on topographic map).

EKCOKCW AVAHABUS. July 21,1907, to February 29, 191B8, and^Junfe 26,1908, to Septeniber 30,, 1918. All tecords prior t» October 1,1915, published In Water-Supply 

Paper 412.

GAGE. Friez water-stage recorder on left bank at Coope? ranch, installed October 2, 

1916; inspected by E. H. Robinson. Previous gages as follows: July 6,1907, to 

August 31,1912, vertical staff at Northern Pacific Railway bridge 2£ miles above 

mouth; September 1, 1912, to October 1, 1916, Fuller and Friez water-stage 

recorders at same site and datum.

DISCHABQE MEASUREMENTS. Made by wading or from cable 145 feet below gage.

CHANNEL AND CONTROL. Bed composed of gravel; shifting at extremely high stages. 

No well-defined control.

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

10.76 feet at 9 a. m. December 18 (discharge, 5,400 second-feet); minimum stage 

1.65 feet at 6 a. m. September 29 (discharge, 88 second-feet).

' 1907-1918: Maximum stage recorded, "Water over gage" November 3,4,19, 23, 

and 29,1909 (gage height and discharge not determined); minimum stage recorded 

0.70 foot October 10,11,1908 (discharge, 68 second-feet). ; 

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed December 18. Rating curves well defined below 3,000 second-feet; extended above. Operation of water-stage recorder 

satisfactory. Daily discharge ascertained by applying to rating table mean daily 

gage height determined by inspecting recorder graph or, for days of considerable 

variation in stage, by averaging results obtained by applying mean gage heights 

for shorter intervals. Partial clogging of intake pip;e after December 18, caused 

lag of water stage in well behind that in river. This caused slight uncertainty 

in daily records for periods of rapidly changing stage, but had little or no effect 

on monthly records. Records good.

SKAGIT RIVER AT REFLECTOR BAR, HEAR MARBLEMOTOT, WASH.

LOCATION. In sec. 8, T. 37 N., B. 13 E (unsurveyed) at Reflector Bar ranger station, 

just "below mouth of Canyon Diahlo, three-quarters of a mile above Stetattle 

Greek, 1J miles below Thunder Creek* and 23 mites (by trail) northeast of Marblemount, Whatcom County.

DRAINAGE ABBA. Not measured.

RECORDS AVAILABLE. December 6, 1913, to September 30, 1918.

GAGE. Stevens continuous water-stage recorder oa right hank, 75 feet below mouth 

of Canyon Diahlo, installed April 13, 1914; inspected by Thomas Thompson, 

F. E. Davis, Glee Davis, and Mrs. L. J. Davis. Prior to April IS, 1914, inclined 

staff at same site but at datum 2.00 feet higher.

DISCHARGE MEASUREMENTS. Made from cable 50 feet below gage.

CHANNEL AND CONTROL. Bed composed of gravel and boulders. Control 200 feet 

below gage composed of large boulders, gravel, and sand; may shift during floods. 

One channel at all stages. Banks not subject to overflow.

EXTREMES 01 DISCHARGE. Maximum stage during year from water-stage recorder, 

12.0 feet at 6.30 p. m. December 29 (discharge, 37,300 second-feet); minimum 

stage from recorder, 1.84 feet at 2 p. m. October 31 (digchajge, 786 second-feet), 

1913-1918: Maximum stage same as above; miniiftiim stage recorded, 1.74 feet 

from 1 to 10 a. m. January 28, 1915 (discharge, 70? second-feet). Hydrographic 

comparison with flow of Sauk River at Darrington, Baker River near Concrete, 

and Skagit River near Sedro Woolley, and study of weather records indicate that 

discharge may have been 700 second-feet January 12, 13, and 31, 1916.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. None.

70985 2& WSP 482 A ;
44 SURFACE WA331B SUPPLY, 1918, PABT XII A.

ACCURACY. StageKlischarge relation changed during flood on December 20. Rating 

curves well denned. Operation of water-stage recorder not entirely satisfactory, 

but good during critical periods. Gage-height record somewhat uncertain owing 

to partial clogging of intake pipe. Daily discharge ascertained by applying to 

rating table mean daily gage height determined by inspecting recorder graph. 

Records fair.

COOPERATION. Station maintained in cooperation with United States Forest Service 

and Skagit Power Co. until about July 1,1918, since which date the city engineer 

of Seattle has furnished gage-height record.

Discharge measurements of Skagit River at Reflector Bar, near Marblemount, Wash,,

three-fourths mile below intake of Beatty's Slough, 1$ miles souljh of Sedro Woolley 

Skagit County, 21 miles above mouth and 32 miles below Baker River.

DRAINAGE AKEA. 2,930 square miles (measured on General Land Office and British 

Columbia maps).

RECORDS AVAILABLE. May 1, 1908, to September 30, 1918.

GAGE. Chain gage on railway bridge, installed September 27,1916; read by E. J. 

Woods. Prior to September 27, 1916, vertical staff on upstream draw guard of 

railway bridge and temporary vertical staff, installed September 25, 1915, used 

when stage was below 37 feet, on downstream side of group of piles, 50 feet 

above third concrete pier of railway bridge from left bank; at same datum. Zero 

of gage set at elevation of extreme low water in Puget Sound.

DISCHARGE MEASUREMENTS. Made from highway bridge one-third mile above 

gage. Beatty's Slough measured from highway bridge.

CHANNEL AND CONTROL. Gravel; shifts at high stages. Banks not subject to overflow except during floods.

EXTREMES OF DISCHARGE. Maximum stage during year determined from highwater marks 54.9 feet at 4.30 a. m. December 30 (discharge, 151,000 second-feet); 

minimum stage recorded, 32.70 feet October 21 (discharge, 4,230 second-feet).

1908-1918: Maximum stage recorded same as above; discharge probably greater 

November 30,1909, rating curve not well defined; minimum stage recorded, 32.3 

feet September 29-30 and October 10-11, 1915 (discharge, 2,740 second-feet).

ICE. Stage-discharge relation seldom affected by ice.

DIVERSION. Beatty's Slough carries from 1.5 per cent of total flow at low stages to 8 

per cent at high stages. Amount determined at each visit and added to flow 

measured in main channel.

REGULATION. None.

ACCURACY. Stage-discharge relation changed December 19, January 3 to February 

7, June 8, and July 19 to August 8. Rating curves fairly well defined. Gage 

read once daily to hundredths. Practically no diurnal fluctuation. Daily discharge ascertained by applying daily gage height to rating table; shifting-control 

method used, January 3 to February 7 and July 19 to August 8. Records good.

channel at all stages. Principal control composed of boulders about 50 feet 

below gage; shifting.

EXTREMES OF DISCHARGE. Maximum stage during the year, as determined by 

leveling to high-water mark, 14.0 feet on December 29 (discharge, 11,000 secondfeet); minimum stage recorded, 1.00 foot, probably on October 20 (discharge, 

75 second-feet).

ICE. None.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed often during the fall of year and during 

flood of June 13, permanent for remainder of year. Eating curves well defined 

between 100 and 2,500 second-feet; extended to 11,000 second-feet by study of 

flood-peak discharge at all stations on Sauk and Skagit rivers. October 1 to 8, 

staff gage read twice daily to hundredths. Water-stage recorder in operation 

October 9 to December 22. Staff gage read three times daily to hundredths 

January 22 to September 30. Daily. discharge ascertained by applying mean

SAT7K RIVER ABOVE WHITECHUCK RIVER, NEAR BARRPTOTON, WASH.

LOCATION. In NW. J sec. 24, T. 31 N., R. 10 E., half a mile above Whitechuck 

River and 9J miles southeast of Darrington, Snohomish County.

DRAINAGE AREA. 152 square miles (measured on topographic maps).

RECORDS AVAILABLE. August 29 to November 17, 1910 (fragmentary). October 1, 

1917, to September 30,1918.

GAGE. Stevens continuous water-stage recorder on right bank; inspected by Nicolai 

Aall. Gage used in 1910 was inclined staff on left bank one-eighth mile above 

Whitechuck River.

DISCHARGE MEASUREMENTS. Made by wading or from cable 75 feet below gage.

CHANNEL AND CONTROL. Bed composed of gravel and boulders; shifting. Principal 

control about 150 feet below gage; shifted during high water. Banks high; not 

subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during the year, 13.3 feet at 

8 a. m. December 29 (discharge, 21,000 second-feet); minimum discharge estimated as 220 second-feet on September 25, when recorder was not in operation.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None. . REGULATION. None.

ACCURACY. Stage-discharge relation changed February 5 to 20. Rating curve used 

October 1 to February 4 well defined below 2,500 second-feet; extended to 21,000 

second-feet by form of later curve and by study of flood-peak discharge at all 

stations on Sauk and Skagit rivers. Rating curve used February 21 to September 

30, well defined below 4,000 second-feet. Operation of water-stage recorder 

satisfactory except as indicated in footnote to table of daily discharge. From 

March 25 to June 14 intake partly clogged. Daily discharge ascertained by 

applying to rating table mean daily gage height determined by inspecting recorder 

graph or, for days of considerable variation in stage, by averaging results obtained 

by applying mean gage heights for shorter intervals; shifting-control method 

used February 5 to 20. Records good except for periods estimated and days of 

extreme high water, for which they are fair.

COOPERATION. Station maintained in cooperation with American Nitrogen Products 

Co.

RECORDS AVAILABLE. June 15, 1914, to September 30, 1918.

GAGE. Vertical and inclined staff on left bank; installed January 7, 1918; read by 

Paul Schmidt. Previous gage, vertical staff at same site and datum; washed out 

December 17, 1917.

DISCHARGE MEASUREMENTS. Made by wading or from suspension bridge 700 feet 

below gage.

CHANNEL AND CONTROL. Bed composed of gravel and large boulders; shifting during 

high water. No well-defined control. Left bank at gage high and not subject 

to overflow; right bank flat and subject to overflow at extremely high stages. 

Stage of zero flow, estimated September 13, 1918, as 1.2 feet.

EXTREMES OF DISCHARGE. Maximum stage during year, determined by levels to highwater mark 15.0 feet at 9 a. m. December 29 (discharge, 36,000 second-feet); 

minimum stage recorded, 1.02 feet October 23 (discharge, 400 second-feet).

1914-1918: Maximum stage same as above; minimum stage recorded, 0.78 foot 

September 28-29, 1915 (discharge, 340 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during December floods. Rating curve 

used October 1 to December 17 well defined below 9,000 second-feet; curve used 

December 29 to September 30 well defined below 10,000 second-feet and extended 

to 50,000 second-feet by study of all known floods in the Skagit River basin. Gage 

read to hundredth^ once daily. Daily discharge ascertained by applying daily 

ga|[e height to rating table. Records excellent, except for periods estimated, for 

which they are fair.

SOUTH FORK OF SATJK RIVER NEAR BARLOW PASS, WASH.

LOCATION.-r-In NE. £ sec. 27, T. 30 N., R. 11E., 2| miles above confluence with North 

Fork and 5 miles northeast of Barlow Pass, Snohomish County,,

DRAINAGE AREA. 32.7 square miles (measured on topographic mapa).

RECORDS AVAILABLE. October 1,1917, to September 30,1918.

GAOE. Stevens continuous water-stage recorder, on right bank; inspected by Nicolai 

Aall.

DISCHARGE MEASUREMENTS. Made by wading near cable or from cable 75 feet below 

gage.

CHANNEL AND CONTROL. Bed composed of boulders and gravel. Principal control 

100 feet below gage; shifting during high water. One channel at all stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during the year 9.1 feet at 

1.30 a. m. December 29 (discharge, 5,800 second-feet); minimum discharge estimated 40 second-feet on September 25 when recorder was out of order.

ICE. Stage discharge relation not affected by ice.

DIVERSIONS . None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed December 29. Rating curve used 

October 1 to December 28, well defined below 200 second-feet, and fairly well 

defined to 2,000 second-feet; curve used December 29 to September 30 well defined below 1,500 second-feet; both curves extended to 5,800 second-feet by 

study of flood-peak discharge at all stations on Sauk and Skagit rivers. Operation 

of water-stage recorder satisfactory except for iour short periods indicated in 

footnote to table of daily discharge. Daily discharge ascertained by applying 

to rating table mean daily gage height determined by inspecting recorder graph 

or, for days of considerable variation in stage, by averaging results obtained by 

applying mean gage heights for shorter intervals. Records good October to 

December, excellent January to September.

COOPERATION. Station maintained in cooperation with American Nitrogen Products Co.

LOCATION. In SE. % sec. 30, T. 37 N., B, 9 E., 350 feet below Anderson Creek, a 

quarter of a mile above Baker River ranger station, ana 11 roilea above Concrete, 

Whatcom County.

DRAINAGE AREA. 184 square miles (measured on topographic maps).

HECORDS AVAILABLE. September 10, 1910, to September 30, 1918.

GAGB. Stevens continuous water-stage recorder, on left bank, installed September 

24,1915; inspected by G. C. Burch and W. L. Stilwell. Previous gages as follows: 

September 10 to November 19,1910, vertical staff at trail bridge one-eighth mile 

above Anderson Creek; readings reduced to datum of gage installed October 22,1910, 

by means of relation curve; October 22, 1910, to September 4, 1913, vertical and 

inclined staff gage on left bank, 30 feet above present gage; September 30, 1913, 

to September 23, 1915, one inclined and two vertical sections at practically the 

same site as the gages previously used but at different datum. Water-stage 

recorder referred to datum of staff gage last used, but slight change in location 

changed the rating.

DISCHARGE MEASUREMENTS. Made from cable 300 feet above gage.

CHANNEL AND CONTROL. Bed composed of boulders and gravel over bedrock; not 

likely to shift except during extremely high water. No well-defined control. 

Bight bank high and rocky; left bank fairly high, wooded, subject to overflow at 

about 11-foot stage.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 13.7 feet at 

12.30 p. m. December 29 (discharge, 36,800 second-feet); minimum stage recorded 

2.43 feet at 4 p. m. March 13 (discharge, 502 second-feet).

1910-1918: Maximum stage same as above; minimum stage recorded, 2.6 feot 

February 27 and March 1, 1911 (discharge, 410 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed December 29. Eating curves well 

defined below 10,000 second-feet; extended above. Operation of water-stage 

recorder satisfactory except as indicated in footnote to table of daily discharge. 

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

determined by inspecting recorder graph, and for a few days during the year 

when there was considerable variation in stage by averaging results obtained by 

applying mean gage heights for shorter intervals. Records good except for 

September, for which they are poor.

GAGE. Chain gage on left span of highway bridge; prior to completion of bridge a 

temporary staff gage fastened to an old stump on the right bank at lower side of 

bridge. In February, 1913, gage datum lowered 2 feet; all readings prior to 

change reduced to new datum.

DISCHARGK MEASUREMENTS. Made from highway bridge; prior to erection of bridge 

from ferry cable.

CHANNEL AND CONTROL. Bed of stream composed of small rocks; permanent. No 

well-defined control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 14,27 feet at 5.30 

p. m. June 13 (discharge, 77,000 second-feet); minimum stage, 1.6ft feet December 

14 (discharge, 1,960 second-feet).

1910-1918: Maximum stage, 19.17 feet June 21, 1916 (discharge., 130,000 second-feet); minimum stage, 1.4 feet February 7, 1914 (discharge, 1,480 secondfeet). (Previously published as 1,690 second-feet.)

ICE. Stage-discharge relation may have been sh'ghtly affected by ice for short periods 

during winter but the open channel rating table has been applied.

DIVERSIONS. None of importance.

REGULATION . None.

ACCURACY. Stage-discharge relation unchanged since 1910 for open-water flow; 

slightly affected by ice. Rating curve well-defined between 3,400 and 25,000 

second-feet and fairly well defined above 25,000 second-feet. Gage 'read to 

hundredth* twice daily during May and June and once daily at other times. 

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

for open channel. Records good except for short periods during winter when 

there may have been slight ice effect on stage-discharge relation.

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

except December 29 to March 7, during which period it was removed on account 

of danger from high water. Staff gage read once daily thretighout the year; to 

half-tenths until May 3, and to hundredths thereafter. Daily discharge ascertained by applying to rating table mean daily gagenheight determined by 

inspecting recorder graph or, for days of considerable fluctuation by averaging 

discharge for shorter interval. Daily staff gage readings used December 29 to 

March 7. Eecords excellent.

DRAINAGE AREA. 5,690 square miles (measured on TJ. S. Geol. Survey maps; scale, 

1:500,000).

RECORDS AVAILABLE. November 5, 1912, to September 30, 1918,

GAGE. Stevens continuous water-stage recorder on left bank; gage datum 1,200 feet 

above mean sea level.

DISCHARGE MEASUREMENTS. Made from cable 50 feet below gage.

CHANNEL AND CONTROL. Bed composed of large boulders; shifting at high stages. 

No well-defined control. Banks high; one channel at all stages.

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

89.8 feet at 6 p. m. January 3 (discharge 39,400 second-feet); minimum mean 

daily discharge, 1,720 second-feet September 15; minimum discharge lower when 

water was below intake (elevation, 75.05 feet) for short periods on July 29, August 

4 and 31, and many days in September.

1912-1918: Maximum stage recorded, 90.32 feet at 8.30 p. m. May 18, 1917 

(discharge, 41,300 second-feet); minimum stage same as above, and for parts of 

days during low-water seasons.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Water is diverted by Spokane Valley Land & Water Co. for irrigation 

above station.

REGULATION. Flow affected considerably by power regulation at Little Falls and 

Long Lake, and slightly by power regulation at Ninemile, Spokane, and Post 

Falls. Low-water flow is affected by regulation of storage in Coeur d'Alene Lake.

ACCURACY. Stage-discharge relation changed January 6 during high water. Rating 

curves well defined. Operation of water-stage recorder satisfactory except as 

indicated in footnote to table of daily discharge. Daily discharge ascertained by 

means of discharge integrator except for periods when recorder was but of order, 

and for period December 29 to January 23, for which mean daily gage height 

determined by inspecting recorder graph was applied to rating table. Records 

excellent.

COOPERATION. Gage-height record furnished by Washington Water Power Co.

LOCATION. In sec. 18, T. 35 N., E. 25 E., half a mile below Conconully reservoir, 

Okanogan project of United States Reclamation Service, 2 miles south of Conconully and 14 miles above Okanogan, Okanogan County.

DRAINAGE AREA. 121 square miles; 164 square miles (revised measurement) at 

Jones ranch (measured on topographic maps).

RECORDS AVAILABLE. July 6,1910, to September 30,1918. Prom April 12,1.903, to 

March 31,1912, records were obtained at Jones ranch in sec. 31, T. 34 N., R. 26 Bi, 

about 3 miles above Okanogan.

GAGE. Vertical staff half a mile below reservoir indicates head on weir; Jread .by 

Alien Honey.

DISCHARGE MEASUREMENTS. Made from footbridge near gage.

CHANNEL AND CONTROL. 20-foot recatangular sharp-crested weir with two end contractions; prior to October 1,1912, a 20-foot Cippoletti weir.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 1.58 feet from 8.45 

p. m. June 12 to 11 p. m. June 13 (discharge, 143 second-feet); minimum stage 

recorded, 0.06 foot on numerous days during October to December (discharge, 

1.3 second-feet). 

1903-1918: Maximum stage recorded, 3.63 feet April 29, 1904 (discharge,.577 

second-feet). No flow 4 p. m. October 3 to 6 p. m. October 11,1910, when water 

was being stored in Salmon Lake and Conconully reservoirs. ......

ICE. Stage-discharge relation not affected by ice. . . DIVERSIONS. None. .

REGULATION. Flow controlled by storage in Salmon Lake reservoir (capacity, 2^600 

acre-feet) and Conconully reservoir (capacity, 13,000 acre-feet). Monthly.summaries of flow for 1912-1918 have been corrected for storage.

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

read to hundredths once daily and oftener when head was changed. Daily 

discharge ascertained by applying daily gage height to rating table or, for days 

when head was changed, by taking weighted mean of results obtained by applying 

to rating table gage heights for various periods of constant head. Records 

excellent.

COOPERATION. Gage-height record and storage determinations furnished by United 

States Reclamation Service.

Two independent discharge measurements were made on June 16 by L. D. Carson. 

During both measurements the gage height was 1.53 feet and discharge, 138 second-feet.

shifts at extremely high stages. No well-defined control. One channel at all 

stages. Right bank high and not subject to overflow; left bank not subject to 

overflow below gage height 12 feet. Stage of zero flow, according to measurements made October 1,1918, gage height 1.3 feet ±0.2 foot.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 9.98 feet at 8.30 

a. m. June 14 (discharge, 9,510 second-feet); minimum stage probably occurred 

during period in which stage-discharge relation was affected by ice.

1903-1918: Maximum stage recorded, 11.6 feet, May 11,1910 (discharge, 14,900 

second-feet). Minimum flow estimated at 230 second-feet January 3 and 4,1912, 

when stage-discharge relation was affected by ice.

ICE. Stage-discharge relation seriously affected by ice; flow estimated from discharge 

measurements, observer's notes, and weather records.

DIVERSIONS. Many-small ditches divert water for irrigation above station.

REGULATION. None,

ACCURACY. (1918) stage-discharge relation changed at high water June 13; affected 

by ice as indicated in footnote to table of daily discharge. Rating curves well 

defined. Gage read to hundredths twice daily. Daily discharge ascertained by 

applying mean daily gage height to rating table. Open-water records excellent, 

others fair.

NOTE. Records prior to Nov. 17,1913, revised since publication in previous water-supply papers, utogodischarge relation changed during high water May 1-5,1911; shifting-control method used May 1-5. Rating curve used prior to change fairly well defined; curve used after the change well denned. Stage-discharge 

relation affected by ice Jan. 1-5,1912, and Jan. 20-22, 25-31, Feb. 1-8,10,11, 13,1913; discharge estimated 

by comparison with record of flow at Dryden and by interpolation. Stage^discharge relation affected by 

logs on control Mar. 17 to May 24,1913; daily discharge ascertained from fairly well defined rating curve. 

Discharge interpolated for days when gage was not read. Revised records good prior to shift in May, 

1911, and for months during which stage-discharge relation was affected by ice or logs on control; excellent 

for remainder of period.

station on Chicago, Milwaukee & St. Paul Railway, 3| miles northwest of Martin, 

and 9£ miles northwest of Easton, Kittitas County.

DEAINAGE AEEA. 55 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 18 to November 14, 1903; January 28, 1904, to September 30, 1918.

GAGE. Inclined staff gage in paved section on left side of outlet works, installed 

December 2, 1916; read by A. L. Flint. Previous gage vertical staff just above 

cable, 1J miles below dam, installed May 4, 1915. For description of former 

gages see Water-Supply Paper 442.

DISCHARGE MEASUREMENTS. Made from cable 1} miles below dam or by wading.

CHANNEL AND CONTROL. Bed composed of gravel; shifts at high stages. Logs and 

brush sometimes lodge on riffle control below gage and cause backwater, affecting 

stage-discharge relation.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 9.2 feet August 9 

to 16 (discharge, 1,840 second-feet); minimum stage, no flow October 8 to November 6, and December 10-16, when reservoir gates were closed.

1904-1918: Maximum discharge, 7,370 second-feet at 10.45 a. m. March 26, 1915, 

when temporary crib dam was washed out (gage destroyed; discharge computed 

from hourly gage readings of lake surface and estimated natural inflow to lake); 

practically no flow when gates in Keechelus reservoir dam are closed.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.
YAKIMA filVER BASIN. 129

REGULATION. Flow partly controlled by storage and release of water at Keechelus 

reservoir. Monthly discharge without storage determined from records of stage 

at reservoir.

ACCURACY. Stage-discharge relation not permament. Rating curves for period Octo-

 ber 1 to December 31, fairly well defined except for extreme low water; curves

for remainder of year well defined. Gage read to hundredths twice daily. Daily

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

Records good.

COOPERATION. United States Reclamation Service furnished field data and ratiaag 

tables.

previous gages see Water-Supply Paper 442.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of gravel and cobblestones; somewhat shifting. One channel at all stages. Control at low water formed by broad riffle 

about 1,200 feet below gage; at high water by a section of stream bed extending 

about one-fourth mile below gage; shifting during high water.

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

11.0 feet at 12.30 a. m. December 30 (discharge, 19,900 second-feet); miniTrnTm 

stage, from recorder, 1.47 feet November 7 (discharge, 286 second-feet).

1.11 feet at 6 p. m. September 30, 1915 (discharge, 192 second-feet).

ICE. Stage-discharge relation not affected by ice during current year.

DIVERSIONS. None.

REGULATION. Flow partly regulated by storage and release of water at Keechelus, 

Kachess, and Cle Elum reservoirs. Monthly discharge" without storage determined from records of stage at reservoirs.

ACCURACY. Stage-discharge relation changing October 1 to December 30; permanent 

thereafter. Rating curves fairly well defined prior to December 30; curve for 

" remainder of year well defined. Water-stage recorder inspected and staff gage 

read twice daily. Operation satisfactory. Daily discharge ascertained by applying to rating table daily gage height ascertained by inspection of recorder graph;

KACHESS RIVER NEAR EASTON, WASH.

LOCATION. In sec. 3, T. 20 N., R. 13 E., three-fourths mile below Kachess storage 

dam, a quarter of a mile above mouth, and 2 miles northwest of Easton, Kittitas 

County.

DRAINAGE AREA. 64 square miles (measured on topographic maps).

RECORDS AVAILABLE. November 20,1903, to September 30,1918.

GAGE. Stevens continuous water-stage recorder at highway bridge, installed August 

15, 1916; inspected by I. Pennington and Fred Diener; original staff gage on 

left bank a quarter of a mile below Kachess storage dam was replaced by waterstage recorder at same site and datum July 22, 1913.

DISCHARGE MEASUREMENTS. Made from cable 20 feet below site of old gage or by 

wading.
YAKIMA BIVER BASIN. 139

CHANNEL AND CONTROL. Bed at old station composed of light gravel and sand; 

shifting frequently. Control formed by broad riffle 125 feet below gage; shifting. 

, High water in Yakima River causes backwater at gage at infrequent intervals.

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

6.38 feet at 8 p. m. September 6 (discharge, 1,290 second-feet). Practically no 

flow November 13 to January 2 and January 27 to April 10.

1904-1918: Maximum stage recorded, 8.0 feet at 8.30 a. m. November 16, 1906 

(discharge; l,760 l second-feet). Practically no flow when gates in dam are 

closed.

ICE. Stage-discharge relation not affected by ice during current year.

DIVERSIONS. None.

REGULATION. Flow controlled by storage and release &f water in Kachess Lake 

reservoir. Monthly discharge, without storage, determined from records of 

stage of reservoir.

ACCURACY. Stage-discharge relation affected by backwater from Yakima River 

January 2-27, April 16-25, May 27 to June 30, and July 31 to September 4 when 

water was being released from Keechelus reservoir and gates were closed at 

Kachess reservoir. Rating curve for normal conditions fairly well defined; 

backwater curve fairly well defined between 500 and 1,200 second-feet and 

poorly defined below. Water-stage recorder inspected once daily; operation 

satisfactory. Daily discharge ascertained by applying mean daily gage height 

to rating table or, for days of considerable variation in stage, by averaging results 

obtained by applying mean gage heights for shorter intervals. Records fair.

COOPERATION. United States Reclamation Service furnished field data and rating 

tables.

Elum Lake, 4 miles northwest of Roslyn, Kitrtitas County, and 7£ mites northwest 

of Cle Elum.

DRAINAGE AREA. 202 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 10, 1903, to September'30, 1918.

GAGE. Stevens continuous water-stage recorder on left bank 800 feet below temporary 

crib dam, installed October 14, 1913; inspected by J. G. Giddings. For description of previous gages see Water-Supply Paper 442.

DISCHARGE MEASUREMENTS. Made from cable about 350 feet below gage 'or by 

wading.

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

high water. No well-defined control. One channel at all stages.

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

13.42 feet, 11 p. m. December 29 to 1 a. m. December 30 (discharge, 14,800 secondfeet); minimum stage recorded, 0.29 foot at 2 p. m. October 31 (discharge, 12 

second-feet).

1904-1918: Maximum stage recorded, 14.05 feet at 2 p. m. November 15, 1906 

(discharge, 18,700 second-feet); minimum stage recorded, zero at 6 p. m. September 28, 1914 (discharge practically zero).

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

DIVERSIONS. None.

REGULATION. Flow partly controlled by storage and release of water at Cle Elum 

Lake reservoir. Monthly discharge without storage determined from records 

of stage at reservoir.

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

4,500 second-feet. Water-stage recorder inspected twice daily. Daily discharge 

ascertained by applying to rating table mean daily gage height determined 

from inspection of recorder graph or for days of considerable variation in stage 

by averaging results obtained by applying mean gage heights for shorter intervals. 

Records excellent except for extremely high water.

COOPERATION. United States Reclamation Service made current-meter measurements and computed discharge.

NACHES RIVER BELOW TIETON RIVER, NEAR NACHES, WASH.

LOCATION. In sec. 35, T. 15 N., ft. 16 E., 600 feet below Tieton River, 500 feet above 

intake of Wapatox power canal, and 5 miles northwest of Naches, Yakima 

County.

DRAINAGE AREA. 942 square miles (measured on topographic maps and drainage 

map published in Water-Supply Paper 369).
144 SURFACE WATER SUPPLY, 1918, PART XII A.

RECORDS AVAILABLE. August 4 to October 28, 1905; March 16, 1909, to October 31,

1912; May 10 to September 30, 1915; April 13, 1916, to September 30, 1918. 

GAGE. Stevens continuous water-stage recorder on left bank, referred to same datum 

as previous gage; installed December 7, 1916; inspected by N. E. Wray, David 

Rasmusson, A. C. Saunders, and Paul Mitchel. Previous gages as follows: 

August 4 to October 28, 1905, vertical staff nailed to stump on left bank at 

nearly same site as present gage but at different datum; March 16, 1909, to 

December 7, 1916, inclined and vertical staff gage on left bank in two sections 

8 feet above cable; April 3, 1916, vertical staff installed to supplement inclined 

and vertical sections.

DISCHARGE MEASUREMENTS. Made from cable at gage.

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

shifts at extremely high water. Control at riffle, 200 feef downstream, shifting 

during high water. One channel except at extremely high stages when a small 

overflow channel at right bank carries water.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 12.7 feet at 4 a. m. 

December 30 (discharge, 16,800 second-feet); minimum stage recorded, 1.62 feet 

at 5 p. m. November 20, and 1.67 feet September 23 (discharge, 202 second-feet). 

1905, 1909-1918: Maximum stage recorded, 8.9 feet at 8 a. m. November 24, 

1909 (discharge, 18,800 second-feet); minimum stage same as above. t 

ICE. Stage-discharge relation not affected by ice during current year. 

DIVERSIONS. Above all important diversions except Selah Valley and Tieton canals. 

REGULATION. Flow partly controlled by storage and release of water at Bumping 

Lake. See record for Bumping Lake and table of monthly discharge for Bumping River near Nile, Wash.

ACCURACY. Stage-discharge relation changed December 29 and June 10; possibly 

affected during periods of low stage by backwater from wing dam extended across 

the river for the purpose of regulating head on Wapatox canal intake. No definite information on effect of backwater, but probably slight. Rating curves well 

defined below 8,000second-feet; extended above. Water-stage recorder in operation October 1 to December 1, December 14 to February 12, April 2 to September 

9, and September 20 to 30, and inspected three times daily during these periods. 

Staff gage read three times daily at other times. Gage-height record fairly reliable. Daily discharge ascertained by applying mean daily gage height to rating 

table. Records good except for periods of extreme low and high water, for which 

they are fair.

COOPERATION. Maintained by United States Reclamation Service in cooperation 

with Pacific Power & Light Co. United States Reclamation Service made discharge measurements and computed discharge.

Discharge measurements of Naches River below Tieton River, near Naches, Wash., during 

the year ending Sept. 30, 1918.

DISCHARGE MEASUREMENTS. Made from cable about 40 feet below gage or by wading.;
YAKIMA RIVER BASIN. 147

CHANNEL AND CONTROL. Bed composed of large angular rocks and gravel; shifts at.

extremely high water. Riffle control.60 feet below gage; shifting during high

water. Stage of zero flow, about gage height 0.6 foot. 

EXTREMES op DISCHARGE. Maximum stage recorded during year, 9.33 feet at 5 p. m._

December 29 (discharge, 5,180 second-feet); minimum stage recorded, 0.96 foot,

gates in outlet conduit are closed. 

ICE. Stage-discharge relation not affected by ice. 

DIVERSIONS. None. 

REGULATION. Flow partly controlled by storage and release of water at Bumping

Lake reservoir. Monthly discharge without storage determined from records of

stage at reservoir. 

ACCURACY. Stage-discharge relation changed at high water of December 29. Curves

used before and after change well defined below 1,500 second-feet. Daily die--

charge ascertained by applying mean daily gage-height to rating table f or, for

days of considerable variation in stage, by averaging results obtained by applying

mean gage heights for shorter intervals. Records good below 100 second-feet and

excellent above. 

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

No discharge measurements were made during the year.

TIETON RIVER AT HEADWORKS OF TIETON CANAL, NEAR NACHES, WASH.

LOCATION. In sec. 30, T. 14 N., R. 15 E. (unsurveyed), below intake of Tieton canal,

15 miles above mouth, and 16 miles southwest of Naches, Yakima County. 

DRAINAGE AREA. 240 square miles (measured on topographic maps). 

RECORDS AVAILABLE. April 17 to September 17, 1906 (fragmentary gage-height

record); July 5, 1907, to September 30, 1918. 

GAGE. Friez water-stage recorder on right bank about 1,000 feet below intake of

Tieton canal; inspected by employees of United States Reclamation Service.

For description of previous gages see Water-Supply Paper 442. 

DISCHARGE MEAsuREMENTS.^-Made from cable about 500 feet below gage or by

wading. 

CHANNEL AND CONTROL. Bed composed of gravel and boulders; shifts slightly at

high water; gradient steep. No well-defined control. One channel at all stages 

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

4.97 feet at 6.30 p. m. June 13 (discharge, 1,720 second-feet); minimum stage

recorded 1.68 feet at 10 a. m. August 28 (discharge, 8 second-feet).

1907-1918: Maximum stage recorded 7.15 feet at 4 a. m. November 24, 1909

(discharge about 5,400 second-feet); minimum stage same as above. 

ICE. Record discontinued during winter. 

DIVERSIONS. Tieton canal has diverted water above the gage since 1910. Diversions

through canal added to mean monthly flow to determine natural monthly discharge. . 

REGULATION. Flow slightly regulated by storage and release of water at Clear Creek

reservoir about 15 miles above gage. Purpose of regulation to obviate diurnal

fluctuation during irrigation season. 

ACCURACY. Stage-discharge relation for low water changed slightly during winter;

permanent during period of records. Rating curve well defined. Water-stage

recorder inspected twice daily. Daily discharge ascertained by applying mean

daily gage height to rating table. Records excellent. 

COOPERATION. United States Reclamation Service furnished field data.

DRAINAGE AREA. 69 square miles (measured on topographic maps).

RECORDS AVAILABLE. August 26, 1907, to September 30, 1918.

GAGE. Stevens eight-day water-stage recorder on left bank, about 300 feet southeast of ranch house, installed April 14,1918; inspected by F. B. Hill. Previous 

gages as follows: August 26, 1907, to April 1, 1913, and August 20, 1915, to September 5, 1916, vertical staff at same site and datum as present gage; April 2, 

1913, to August 19, 1915, and September 6,1916, to September 30, 1917, Stevens 

continuous water-stage recorder at same site and datum.

DISCHARGE MEASUREMENTS. Made from gaging bridge 40 feet below gage or bywading.

CHANNEL AND CONTROL. Bed composed of gravel and boulders. Concrete control 

50 feet below gage installed in November, 1915, slightly shifting. Stage of zero 

flow at time of construction of control, gage height 1.45 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.13 feet at 9 p. m_ 

June 10 (discharge, 275 second-feet); minimum stage recorded, 1.76 feet during 

October (discharge, 17 second-feet); actual minimum probably occurred in the 

winter period of no record.

1907-1918: Maximum stage recorded, 4.60 feet at 9 a. m. June 18, 1916 (discharge, 728 second-feet); minimum stage recorded 1.60 feet at noon November 12^ 

1916 (discharge, 7 second-feet).

ICE. Stage-discharge relation seriously affected by ice. Record discontinued during 

winter.

YAKIMA BIVEB BASIN. 161

RESBfcVATION DRAIN AT ALFALFA, WASH.

LOCATION. In sec. 29, T. 10 N., JR.. 21E., at highway bridge a quarter of a mile southeast of Alfalfa, Yakima County, about 2 miles above mouth of drain.

RECORDS AVAILABLE. December 5,1912, to September 30,1918; miscellaneous measurements 1911 aad 1912.

GAGE. Vertical itaff on right bank under highway bridge; read by Miss Nellie Ide.

DISCHARGE MEASUREMENTS. Made from footbridge 1,000 feet below gage.

CHANNEL AND CONTROL. Bed composed of gravel; shifting. No well-defined control.

EXTREMES OF DISCHARGE. Maximum stage during year, 8.2 feet on January 2, from 

high-water mark (discharge, estimated 1,500 second-feet); minimum stage recorded, 2.92 feet October 16 and 17 (discharge, 214 second-feet).

1913-1918: Maximum stage same as above; minimum stage recorded, 1.8 feet. 

July 3, August 12, 15-31, September 1-14, 19, 1915 (discharge, 145 second-feet).

ICE. Ice does not form at this station.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed several times during the year. Five 

rating curves, all parallel to a standard curve developed in previous years, and 

shifting-control method were used. Curves well defined below 500 second-feet. 

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

daily gage height to rating table. Records excellent except for the high water 

early in January; daily discharge December 31 to January 2 is rough estimate 

only.

COOPERATION. Most of discharge measurements made by United States Office of 

Indian Affairs.

Reservation drain carries the return water from irrigation by the reservation canals 

and the underflow of Toppenish Valley. During the low-water period practically 

the whole flow of Toppenish Creek is carried into this channel by seepage.
