COLUMBIA BIVEE BASIN, 1921.

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, 1921.

The data presented in these reports were collected by the United 

States Geological Survey under authority implied in the organic law 

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

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

iogical Survey and the classification of public lands and examination of the 

geological structure, mineral resources,, and products of the national domain.

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

water supply for irrigation. Since the fiscal year ending June 30, 

1895, successive sundry civil bills passed by Congress have carried 

the followingitem' an*d 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

EXPLANATION OF DATA.

The datar presented in this report cover the year beginning October I, 1920, and ending September 30, 1921.: At the first of January, 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, and swamps, and this stored water 

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

September, on the other hand, the only stored Water available for 

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

precipitation within that year.

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

stage, measurements of discharge, and general information used to 

supplement the gage'heights and discharge measurements in determining the daily flow. The records of stage are obtained either 

from direct readings on a staff or chain gage or from a water-stage 

recorder that gives a continuous record of the fluctuations. Measurements of discharge are made with a current meter by the general 

methods outlined in standaf d textbooks on the measurement of river* 

Discharge. (See Pis. I and II.)

From the discharge measurements rating tables are prepared that 

give the discharge for any stage. The application of the daily gage 

heights to these rating tables gives the daily discharge from which 

the monthly and yearly mean discharge are computed.

The datli, presented for each gaging station in the area covered by 

this report comprise a description of 'the station, a table giving 

results of discharge measurements, a table showing the daily discharge, and a table of monthly and yearly discharge, and run-off.

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

tables giving daily gage heights and results of discharge measurements are published.

The description of the station gives, in addition to statements 

regarding location and equipment, information in regard to any 

conditions that may affect the permanence of the stage-rdischarge 

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

the stream for log driving, shifting of channel, and the cause and 

effect of backwater. It gives also information as to diversions that 

decrease the flow at the gage, artificial regulation, maximum and 

minimum recorded stages and the accuracy of the records.

Hie table, of daily discharge gives the discharge in second-feet 

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

stations on streams subject to sudden or rapid diurnal fluctuation

84390 24t WSP 532 2 ''
4 SURFACE WATER SUPPLY, 1921, PART XII A.

the discharge obtained from the rating table and the mean daily 

gage heights may not be the true mean discharge for the day. If 

such stations are equipped with water-stage recorders, the mean 

daily discharge may be obtained by weighting discharge for parts of 

the day or by use of the discharge integrator, an instrument operating on the principle of the planimeter and contrming as an essential 

element the rating curve of the station.

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

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

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

indicate correctly the stage >when the water surface was at crest 

height, and the corresponding discharge was consequently larger than 

that given in the column. Likewise, in the column headed "Minimum," the quantity given is the mean flow for the day when the 

mean gage height was lowest. The column headed "Mean" gives 

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

this average flow computations recorded, in the remaining columns, 

which are defined on pages 2 and 3, 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 observations of stage, measurements of flow, .and interpretation 

of records.

A paragraph in the description of the station or footnotes added 

to the tables gives information regarding the (1) permanence of the 

stage-discharge relation, (2) precision with which the discharge rating 

curve is defined, (3) refinement of gage readings, (4) frequency of 

gage readings, and (5) methods of applying daily gage heights to 

the rating table to obtain the daily discharge.

For the rating curves "well defined" indicates, in general, that the 

rating is probably accurate within 5 per cent; "fairly well defined/* 

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

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 gagej but the figures 

showing discharge per square mile and deptla of run-off in inches 

may be subject to gross errors caused by.including 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 effecjt of artificial regulation of the 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
5

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

"run-off in inches" published by the Survey in earlier reports should 

be used with caution because of possible inherent sources of error 

not known to the Survey. . ;

Many gaging stations on streams in the irrigated areas of the 

United States are located above most of the diversions from those, 

streams, and the discharge recorded does not show the water supply available for further development, as prior appropriations below 

the stations must first be satisfied. To give an idea of the amount 

of prior appropriations, a paragraph on diversions is presented in 

each station description. The figures given can not be considered 

exact but represent the best information available.

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

flow at the station and should not be used for other than preliminary 

estimates; the tables of daily discharge allow more detailed studies 

of the variation in flow. It should be borne in mind, however, that 

the observations in each succeeding year may be expected to throw 

new light on data previously published. , PUBLICATIONS.

Investigation of water resources by the Unite<d States Geological 

Survey has consisted in large part of measurements of the volume of 

flow of streams and studies of the conditions affecting that flow, but 

H has comprised also investigations of such closely allied subjects as 

irrigation, water storage, water powers, underground waters, and 

quality of waters. Most of the results of these investigations have 

been published in the series of water-supply papers, but some have 

appeared in the bulletins, professional papers, monographs, and annual reports. ' "'

The results of stream-flow measurements are now published annually in 12 parts, each part covering an area whose boundaries

The records at most of the stations discussed in these reports 

extend over a series of years, and miscellaneous measurements at 

many points other than regular gaging stations have been made 

each year. An index of the. reports containing records obtained 

prior to 1904 has been published in Water-Supply Paper 119.

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

1921. The data for any particular station will, as a rule, be found in 

the reports covering the years during which the station was maintained. For example, data for Machias River at Whitneyville, Maine, 

1903 to 1921, are published in Water-Supply Papers 97, 124, 165, 201, 

241, 261, 281, 301, 321, 351, 381, 401, 431, 451, 471, 501, and 521, 

which contain records for the New England streams from 1903 to 

1921. Results of miscellaneous measurements are published by 

drainage basins.

COOPERATION.

The work in Washington, Montana, and Idaho was carried on under cooperative agreements between the United States Geological 

Survey and the respective States.

Cooperation with the States is effected under contracts which are 

made between the Director of the United States Geological Survey 

and the State engineers or other officials and are authorized by 

legislative acts appropriating money.

During the first half of the climatic year the work in Washington 

was carried .on in cooperation with the Board of Geological Survey, 

composed of Louis F. Hart, governor and chairman of board; W. W. 

Shennan, State treasurer and secretary of board; Henry Suzzallo, 

president of the University of Washington; and E. 0. Holland, 

president of the State College. The board was represented in the 

cooperative investigations by Henry Landes, State geologist. A 

new administrative code became effective in Washington April 1, 

which transferred the functioning of the Board of Geological Survey 

to the Department of Conservation and Development, Dan A. 

Scott, director. During the last half of the climatic year cooperative relations with the new department were administered by Marvin Chase, supervisor of hydraulics.

Acknowledgments are due to C. S. Heidel, State engineer of 

Montana, and to W. G. Swendsen, commissioner of reclamation of 

Idaho, for the efficient manner in which they represented their 

States in the cooperative investigations.

Acknowledgments are also due to the United States Bureau of 

Reclamation, 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. The United States Weather Bureau furnished hydrographic 

and climatologic data used in discharge computation for a number of 

streams.

The Straits Power Co. cooperated in maintaining the stations on 

Soleduck River near Fairholm, Wash., and on Lyre River at Piedmont, Wash., the city of Tacoma cooperated in maintaining the 

stations on North Fork of Skokomish River near Hoodsport, Nisqually River near La Grande, East Creek near Elbe, Little Nisqually River near Alder, and Tacoma power conduit near La Grande, 

Wash., and the American Nitrogen Products Co. cooperated in 

maintaining the stations on Whitechuck River near Darrington and 

Suiattle Itiver below Lime Creek, near Darrington, Wash.

Acknowledgment is made in the description of gaging stations 

for gage-height records and discharge measurements furnished by 

cooperating parties.

Prof. Paper 7).

RECORDS AVAILABLE. October 29, 1911, to September 30, 1921.

GAGE. Stevens continuous water-stage recorder on left bank 350. feet below 

Olympic Highway crossing at outlet of Quinault Lake; installed September 

27, 1916, at different datum from previous gage; inspected by Fred Halbert.. 

For description of previous gages see Water-Supply Paper 512.

DISCHABGE MEASUREMENTS. Made from cable 700 feet above gage.

CHANNEL AND CONTKOL. Bed composed of boulders. Well-defined control 

600 feet below gage. Left bank high and wooded, and not subject to overflow; right bank high, wooded, and subject to overflow above gage, height 

about 20 feet.

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

recorder, 10.9 feet at 11 p. m. February 11 (discharge, 20,100 gecond-fe'et) ;. 

minimum stage, from recorder, 1.65 feet at 10.30 a. m. September 18 (discharge, 765 second-feet).

1911-1921: Maximum stage recorded, 16.3 feet at 8 a. m. January 6,. 

1914 (discharge, 32,500 second-feet); minimum stage recorded, 0.1 foot a't 

7 a, m. October 1, 1915 (discharge, 395 second-feet). / ,

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

DIVERSIONS. None.

REGULATION. Fjow regulated by natural storage in the lake.

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

Operation of water-stage recorder satisfactory except as* noted in footnoteto table of daily- discharge. Daily discharge ascertained by applying torating, table daily mean gage height obtained by inspecting recorder, graph1 

or, for days of considerable variation in stage, by averaging resume, phtai$e,d, 

by applying to rating table mean gage heights for shorter intervals. Records excellent.

wading.

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

to shift. One channel at all stages. Banks high and wooded.

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

recorder, 9.5 feet at 11.30 a.m. February 11 (discharge, 13,100 second-feet); 

minimum stage, from recorder, 0.88 foot September 17-18 (discharge, 140 

second-feet).

1918-1921: Maximum stage, from recorder, 11.7 feet at 6 a. m. December 

18, 1917 (discharge, 18,600 second-feet); minimum stage, from recorder, 0.48 

foot September 29 and October 2 and 3, 1918 (discharge, 58 second-feet).

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

below 8,000 second-feet. Operation of water-stage recorder satisfactory 

except as noted in footnote to table of daily discharge. Daily discharge 

ascertained by applying to rating table daily mean gage height determined 

by inspection of recorder graph or, for days of considerable variation in 

stage, by averaging results obtained by applying to fating table mean gage 

heights for shorter intervals. Records fair for periods of flat estimates; 

otherwise excellent.

PtTOET SOUND BASINS.

SKOKOMISH EIVEE BASIN. 

WORTH FORE OF SKOKOMISH RIVER NEAR HOODSPORT, WASH.

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

Service trail to South Fork of Skokomish River, 4 miles below Lake Cushman and 4 miles northwest of Hoodsport, Mason County.

DRAINAGE AREA. 91 square miles (measured on PL I, U. S. Geol. Survey Prof. 

Paper 7 and township plats).

RECORDS AVAILABLE. August 17, 1910, to September 22, 1911; February 1> 

1913, to September 30, 1921.

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

 inspected by Phillip Abbey. Fragmentary records, 1910-11, obtained from 

vertical staff 25 feet below bridge.

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

wading.

CHANNEL AND CONTROL. Channel curved above gage; straight below gage for 

200 feet. Banks high; not subject to overflow. .Control composed of rock 

and gravel; slightly shifting at extremely high stages.

EXTREMES OF DISCHARGE. Maximum stage during year, from slightly damaged 

record of water-stage recorder, 11.0 feet, probably on February 11 (discharge, 5,680 second-feet); minimum stage, from recorder, 1.23 feet September 17-18 (discharge, 176 second-feet).

1913-1921: 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, 0.77 foot September 28, 1918 (discharge, 89 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION,. Mow regulated by natural storage at Lake Cushman.

ACCURACY. Stage-discharge relation changed February 11-12. Two rating 

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

noted in footnote to table of daily discharge. Daily discharge ascertained, 

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

graph by inspection or, for days of considerable variation in stage, by averaging results obtained by applying to rating table mean gage heights, fo£ 

shorter intervals. Records excellent.

20 SURFACE WATEB SUPPLY, 1921,. PART XII A.

NISQUALLY RIVER BASIN. 

NISQITAIIY BIVER HEAR LA ORANDE, WASH.

LOCATION. In sec. 9, T. 15 N., R. 4 E., 1,200 feet below diversion dam of city 

of Tacoma's municipal power plant and 2^ miles southeast of La Grande, 

Pierce County.

DBAINAGE AEEA. 287 square miles (measured on topographic map of Rainier 

National Park, map of Rainier National Forest, edition of 1818, and Plate 

IV, Water-Supply Paper 313).

RECORDS AVAILABLE. October 1, 1919, to September 30, 1921; September 5f 

1906, to October 31, 1911, fragmentary records showing total flow.

GAGE. Stevens long-distance recorder on left bank 1,200 feet below dam; 

inspected by headgate attendants. Previous gages as follows: From September 5, 1906, to September 8, 1910, vertical staff in two sections on right 

bank near site of present gage; January 1, 1910, to December 31, 1911, 

vertical staff on right wall of canyon at power-house site.

DISCHARGE MEASUBEMENTS. Made from cable 250 feet below gage or by wading.

CHANNEL AND CONTROL. Bed composed of bedrock and boulders. Banks high. 

A considerable amount of glacial silt is deposited during summer, causing 

control to change temporarily.

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

recorder, 12.8 feet December 30 (discharge, 11,800 second-feet). Probably 

no flow at gage for parts of several days in September when entire flow was 

diverted into power conduit.

 1920-21: Maximum stage recorded on December 30, 1920. Probably no 

flow at gage for parts of days when entire flow is diverted into power conduit.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. City of Tacoma diverts water 1,200 feet above gage for power 

purposes. Total monthly discharge is computed from determinations of 

combined flow of river and power conduit.

ACCURACY. Stage-discharge relation permanent except as affected by silt, flushed 

from conduit settling basin and,from behind dam, July 21 to September 30. 

Rating curve for normal control conditions well defined. Rating curves 

parallel to normal curve used for short periods July 21 to September 20, 

Shifting-control method used September 21-30. Operation of water-stage 

recorder satisfactory. Daily discharge ascertained by use of discharge 

integrator except for extremely high water, when discharge was.determined 

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

graph by inspection or, for days of considerable variation in stage, by 

averaging results obtained by applying to rating table mean gage heights for 

shorter intervals. Records excellent except those for August and September, 

which are subject to error owing to uncertain backwater effect of silt deposits.

PUYAIIUP RIVER AT ALDERTON, WASH.

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

R. 5 E., at highway bridge 1 mile north of Alderton, Pierqe County,-and 

1^4 miles above Stuck River.

DBAINAGE ABBA. ilO square miles (measured on PI. IV, Water-Supply Paper 

313).

RECORDS AVAILABLE, November 20, 1914, to September 30, 1921.

GAGE. Chain gage on highway bridge; installed December 15, 1920; read by 

Mrs. H. D. Foster and Miss Edith Johnson. Vertical staff in two sections 

on downstream side of bridge pier on right bank used prior to January 15, 

1920. Several temporary staff gages just below bridge used January 16 to 

December 14, 1920. Datum of gage lowered 1.00 foot August 5, 1918.

DISCHARGE MEASUREMENTS. Made from bridge at gage or, occasionally, from 

bridge 2}4 miles upstream.

CHANNEL AND CONTROL. Bed composed of silt and gravel; shifting. Right 

bank is overflowed at gage height about 9 feet; left bank high and not subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 7.58 feet at 

2 p. m. December 30 (discharge, 11,200 second-feet); minimum stage recorded, 0.70 foot September 16 (discharge, 460 second-feet).

1915-1921: Maximum stage recorded, 12.6 feet at 8 p. m. December 18, 

1917 (discharge, 19,300 second-feet); minimum discharge recorded, 342 secondfeet October 10, 1919,

ICE. Stage-discharge relation slightly affected by ice for short periods during 

severe winters.

DIVERSIONS. None.

REGULATION, The operation of Puget Sound Power & Light Co.'s plant at 

Electron does not materially affect natural flow as the pondage -utilized is 

small.

ACCURACT. Stage-discharge relation changed October 4 and December 29, 

and gradually December 30 to February 11. Three rating curves fairly 

well defined. Shifting-control method used December 30 to February 11. 

Gage read to half-tenths once daily October to December; to hundredth s 

once daily thereafter. Slight- diurnal fluctuation. Daily discharge ascer 

tained by applying daily gage height to rating table or by shifting-control 

method. Records good.

 COOPERATION. Gage-height record furnished by Inter-County River Improvement Commission of King and Pierce counties.

PUYAIIUP RIVER AT PUYAIIUP, WASH,

LOCATION. Since November 16, 1919, in NE. >| sec. 20, T. 20 N., R. 4 E., 

seven-eighths of a mile below Puget Sound Electric Co.'s railway bridge, 

1 mile northwest of Puyallup, Pierce County, three-fourths of a mile above 

Clark Creek, and 3J^ miles below mouth of Stuck River.

DRAINAGE AREA. 914 square miles (measured on Pis. IV and XI, Water-Supply 

Paper 313).

RECORDS AVAILABLE. May 1, 1914, to September 30, 1921.
PUGET SOUND BASINS. 31

GAGE. Stevens continuous water-stage recorder on left bank since December 3, 

1919. Previous gages as follows: May 1, 1914, to November 15, 1919, 

Stevens continuous water-stage recorder on right bank about 1% miles 

above present site and at different datum; July 24, 1918, to December 3, 

1919, Stevens continuous water-stage recorder on left bank about 400 feet 

above present location and at datum approximately 10 feet lower than 

present gage.

DISCHARGE MEASUREMENTS. Made from cable 50 feet below gage.

CHANNEL AND CONTROL. Stream bed composed of light 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, 13.60 feet at 12.30 p. m. December 30 (discharge, 24,900 secondfeet); minimum discharge as low as 1,320 second-feet on September 13 and 

14, and probably lower on same and other days when water surface was 

below stilling-well intake.

1914-1921: Maximum stage recorded, 34.15 feet at 4.45 p. m. December! 

18, 1917 (discharge, 40,500 second-feet); minimum stage recorded, 17.36 

feet at 8 p. m. November 18, 1917 (discharge, 726 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Two hydroelectric plants, owned by Puget Sound Power & Light 

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

from Puyallup River 10 miles above Electron, into an equalizing basin 

having a capacity of 185 acre-feet; water used at this plant is returned 

directly to the river. Water for the Dieringer plant is diverted from White 

River at 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 30, April 22, and continuously from June 2 to September 30. Standard rating curve well defined; 

used December 30 to April 22. Parallel curves used October 1 to December 

29 and April 23 to June 1. Shifting-control method used June 2 to September 30. Operation of water-stage recorder satisfactory except as noted 

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

applying to rating table mean daily gage height obtained by inspecting 

, recorder graph except for period for which shifting-control method was 

used, and exfeept for period August 19 to September 30 for which it was 

determined by applying a single daily staff gage reading, corrected for shifting control, to the rating table, the resulting discharge being corrected by 

a predetermined coefficient to reduce it to mean discharge for the day. 

Records good October to July except those estimated; others fair.

COOPERATION. Gage-height record furnished by Inter-County River Improvement Commission of King and Pierce counties.

PUQBT SOUND BASINS. 33 

WHITE RIVER AT BUOKLET, WASH.

LOCATION. In SE. M sec. 34, T. 20 N., Ri 6 E., at Northern Pacific, Railway 

bridge 1 mile northeast of Buckley, Pierce County.

DRAINAGE AREA. 424 square miles (measured on PI. XI, Water-Supply Paper 

313).

RECORDS AVAILABLE. April 22, 1899, to August 31, 1903 (gage-height record 

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

January 18, 1913, to September 30, 1921.

GAGE. Stevens eight-day water-stage recorder on left bank 40 feet below railway bridge at end of concrete wall protecting abutment of bridge; installed 

January 9, 1917; inspected by O. E. Osgood. Record from this gage supplemented during extremely low water April 25 to May 8, 1920, by measurements from a reference point on railway bridge to water surface, arid after 

May 9, 1920, by readings from chain gage installed at same reference point. 

For description of previous gages see Water-Supply Paper 462.

The high water on January 23, 1919, cut through the left bank, making a 

channel back of the water-stage recorder. In this channel a staff gage was 

installed at railway bridge April 2, 1919; moved 700 feet upstream June 11, 

1919. Gage read by O. E. Osgood and F. C. Rowland.

DISCHARGE MEASUREMENTS. Measurements of flow in both channels made by 

wading or from railway bridge.

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

gradient steep. One channel prior to flood of January 23,1919; two channels 

thereafter. Right bank of main channel low and flat; left bank protected 

by concrete wing wall. Various types of protection to under crossing of 

city of Tacoma's municipal water supply have also been factors in control 

for this station.

EXTREMES OP DISCHARGE. Maximum combined daily discharge of river and 

flume, 12,100 second-feet December 30; minimum combined daily discharge, 

456 second-feet September 16.

1899-1901; 1911; 1913-1921: Maximum daily discharge, including flume, 

18,100 second-feet December 18, 1917; minimum daily discharge, including 

flume, 349 second-feet November 19, 1917.

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 for main channel changed several times 

during year, the most radical change taking place when the city of Tacoma's 

pipe-line protection was destroyed by flood on February 10. Stage-discharge 

relation for secondary channel changed gradually January 1-14. Two 

standard rating curves used for main channel; the first, applicable October 1 

to February 10, well defined; the second, applicable February 10 to September 30, well defined below' 5,000 second-feet. Curves parallel to first standard curve were used October 1-5, October 5 to November 20, November 20 

to December 30, December 30 to January 5, and January 18 to February 10. 

Shifting-control method used January 6-17. The second standard curve 

was used direct -March 18 to September 15; parallel''curves used February 

10 to March 17 and September 16-26; shifting-control method used 

September 27-30. For the secondary channel, two poorly defined rating 

curves were used, applicable October 1 to January 1 and January 15 to 

August 26; no curve defined for period January 2-14. Water-stage recorder 

on main channel operated satisfactorily. Staff gage on secondary channel 

read to hundredths once or twice daily. Daily discharge for main channel 

ascertained by applying to rating table mean daily gage height determined 

from recorder graph by inspection or, for days of considerable variation in 

stage, by averaging results obtained by applying to rating table mean gage
34 SURFACE WATER SUPPLY, 1921, PART XII A.

heights for shorter intervals. Daily discharge for secondary channel ascertained by applying daily or mean daily gage height to rating table, except 

for many days for which gage readings are not an index of the mean discharge for the day owing to flume regulation, for. which discharge was 

ascertained by a comparison with flow in flume and main channel. Daily 

discharge in the table given below is the combined flow of the main and 

secondary channels. Records fair.

COOPERATION. Puget Sound River & Light Co. furnished gage-height record 

and discharge measurements.

WHITE RIVER FLUME AT BUGKLEY, WASH.

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

White River half a mile above Northern Pacific Railway crossing and 1 mile 

northeast of Buckley, Pierce County.

RECORDS AVAILABLE. January 18, 1913, to September 30, 1921,

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

well, on right side of flume 800 feet below headgate, and recorder in gatehouse; installed January 12, 1918; inspected by O. E. Osgood. Prior to 

January 12, 1918, Fuller water-stage recorder 800 feet below headgate.

DISCHARGE MEASUREMENTS. Made from footbridge 8 feet below 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 or DISCHARGE. Maximum stage during year, from water-stage 

recorder, 6.10 feet at 1.30 p. m. May 13 (discharge, 1,800 second-feet); no 

flow in flume when headgates are closed.

1913-1921: Maximum stage, from water-stage recorder, 6.20 feet at 4.30 

p. m. October 28, 1918 (discharge, 2,140 second-feet); no flow in flume when 

headgates are closed.

ICE. Stage-discharge relation affected by ice during severe winters.

REGULATION. Gates at intake are operated frequently to control flow.

ACCURACY. Stage-discharge relation permanent October to December; changed 

continuously thereafter; not affected by ice. Rating curve ftsed October 1 

to December 31, well defined. Shifting-control method used January 1 to 

September 30, with an arbitrary standard curve. Operation of water-stage 

recorder satisfactory. Daily discharge October to December ascertained by 

applying to rating table mean daily gage height obtained from recorder 

graph by inspection or, for days of considerable variation in stage, by 

averaging results obtained by applying to rating table mean gage heights for 

84390 24f WSP 532 4

shorter intervals. Daily discharge January 1 to September 30 ascertained 

by use of discharge integrator after adjusting gage-height graph in accordance 

with the method used for shifting control. Records excellent October to 

December; good for remainder of year.

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

and discharge measurements.

Flume diverts water from left bank of White River in SE. £ sec. 35, T. 20 N.,

CEDAR RIVER NEAR 1ASDSBERG, WASH.

LOCATION. In sec. 17, T. 22 N., R. 7 E., 1M miles above intake of Seattle 

water-supply system at Landsberg, King County, 3 miles northeast of 

Ravensdale, and 5 miles below Taylor Creek.

DRAINAGE AREA. 135 square miles (measured on topographic maps). .

RECORDS'AVAILABLE. April 30, 1914, to September 30, 1921; July 25, 1895, to 

September 30, 1898, at Clifford Bridge, 2 miles below present gage; March 

.24, 1901, to April 30, 1912, at intake of Seattle water-supply system, 1% 

miles below present gage. ' Early records not exactly comparable with those 

for present site because of small difference in drainage area.

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

29, 1914; inspected by T. S. Beals.

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

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

formed by broad riffle about 1, 200 feet below gage; shifts at extremely high 

water. Logs may lodge on riffle. One channel at all stages. Stage of 

zero flow, according to measurements made August 27, 1916, about gage 

height 2.5 feet.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage recorded, 7.9 feet February 11-12 (discharge, 1,920 second-feet); minimum 

stage, from recorder, 4.52 feet on September 18 (discharge, 262 second-feet). 

1914-1921: Maximum stage, from recorder, 13.55 feet at 10 p. m. December 29, 1917 (discharge, 7,500 second-feet); minimum stage, from recorder, 4.35 feet at 1 a. m. October 15, 1914 (discharge, 162 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None above station.

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

Lake reservoir to accommodate requirements of Seattle municipal power 

plant.

ACCURACY. Stage-discharge relation changed May 10. Two rating curves 

well defined. Operation of water-stage recorder excellent. Daily discharge ascertained by use of discharge integrator. Records excellent except for period March to July for which, because of doubt as to rating applicable, records are considered good.

COOPERATION. Gage-height record furnished by city engineer of Seattle.

SNOHOMISH EIVEB BASIN. 

SOUTH FORK OF SKYKOJOSH RIVEB NEAR INDEX, WASH.

LOCATION. In NE. M sec. 29, T. 27 N., R. 10 E., 300 feet above Sunset Falls, 

2 miles southeast of Index and mouth of North Fork, Snohomish County.

DRAINAGE AREA. 351 square miles (measured on topographic and county maps).

RECORDS AVAILABLE. October 1, 1902, to September 30, 1905; April 26, 1911, 

to September 30, 1921.

GAGE. Stevens continuous water-stage recorder on right bank; installed September 14, 1920; inspected by F. C. Doolittle. Prior to September 14, 

1920, inclined and vertical staff gage at same site and datum. Location 

of gage unchanged since establishment. Datum raised 0.61 foot April 26, 

1911, and lowered 1.00 foot to same datum as present gage April 19, 1914.

DISCHARGE MEASUREMENTS. Made from cable 1 mile below gage, from bridge 

100 feet below gage, or by wading nearly 1 mile below gage.

CHANNEL AND CONTROL. Bed at measuring section composed of gravel and 

small boulders. Sunset Falls, 300 feet below gage, forms solid rock control. 

Stage-discharge relation changed by blasting at falls in July, 1914, and by1 

shifting of channel above falls during floods.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage recorder, 14.7-feet at 8 p. m. February 11 (discharge, 21,000 second-feet); 

minimum stage, from recorder, 1.37 foot at 2 a. m. September 18 (discharge, 

466 second-feet).

1902-1905; 1911-1921: Maximum stage recorded, 22.6 feet at 9 a. m. 

December 18,1917 (discharge, 47,000 second-feet); minimum stage recorded, 

0.54 foot September 30, 1915 (discharge, 262 secorid*f eet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent. Rating curve well defiled below 16,000 second-feet. Operation of water-stage recorder satisfactory 

except as noted in footnote to table of daily discharge. Daily discharge 

ascertained by applying to rating table mean daily gage height obtained 

from recorder graph by inspection or, for days of considerable variation in 

stage, by averaging results obtained by applying to rating table mean gage 

heights for shorter intervals. Records excellent.

COOPERATION. Gage-height records furnished by Stone & Webster Engineering 

Corporation.

SULTAN BIVEB NEAB SULTAN, WASH.

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

Sultan and mouth of river, Snohomish County.

DEAINAGE ABE A. Not measured.

RECORDS AVAILABLE. August 18, 1911, to September 30, 1921.

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

above Horseshoe Bend; inspected by employees of city of Everett. Prior 

to October 29, 1915, Lietz water-stage recorder at Camp Habecker 1% 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 during year, from water-stage 

recorder, 1^.4 feet 6 p. m. to 7 p. m. February 11 (discharge, 14,400 secondfeet); minimum stage recorded, 0.93 foot at 6 a. m. September 18 (discharge, 

106 second-feet).

1911-1921: Maximum stage recorded, 16.6 feet at about 9 a. m. December 

18,1917, determined from high-water mark in well (discharge, 20,600 secondfeet); minimum stage recorded, 0.28 foot August 24, 1920 (discharge, 54 

second-feet).

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

during very cold weather.

DIVERSIONS. City of Everett diverted about 3 second-feet above station for 

municipal water supply from July 1, 1918, to July 1, 1919, and about 7% 

second-feet thereafter (estimated at reservoir in Everett by the project 

engineer).

REGULATION. None.

ACCURACT. Stage-discharge relation permanent; not affected by ice. Rating 

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

as noted in footnote to table of daily discharge. Daily discharge, except as 

noted in footnote to table of daily discharge, ascertained by applying to 

rating table mean daily gage height obtained from recorder graph by inspection or, for days of considerable variation in stage, by averaging results 

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

January and February good, otherwise excellent.

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

MIDDLE FORK OF SWOQUAIMIE RIVER WEAR WORTH BEND, WASH.

LOCATION. In NE. ^ SE. ^ sec. 10, T. 23 N., R. 8 E., 1 mile southeast of North 

Bend, King County, and 2|^ miles above junction with North Fork.

DBAINAGE AREA. 184 square miles (measured on topographic and county maps).

RECORDS AVAILABLE. August 10, 1907, to February 29, 1908; August 25, 1908, 

to September 30, 1921.

GAGE. Stevens continuous water-stage recorder on left bank; installed August 

7, 1915; inspected by A. R. Neth. Prior to August 7, 1915, various gages at 

highway bridge 2^ miles below present site were used.

DISCHARGE MEASUREMENTS. Made by wading or from highway bridge at 

original station.

CHANNEL AND CONTROL. Bed composed of large boulders. Channel slightly 

curved above and below station. Control shifts at extremely high water 

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

according to measurements made September 11, 1919, gage height 0.7 foot

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

recorder, 9.2 feet at 5 a. m. December 30 (discharge, 11,800 second-feet); 

minimum stage, from recorder, 1.87 feet August 28 and 29 (discharge, 275 

second-feet).

1907-1921: Maximum stage, from recorder, 12.2 feet at 10 a. m. December 

18, 1917 (discharge, 18,300 second-feet); discharge may have been greater 

during floods in November, 1909, and November, 1910; minimum stage, from 

recorder, 1.50 feet at 1 p. m. September 30, 1915 (discharge, 146 second-feet)..

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

RE GTTLATION. None.

ACCURACY. Stage-discharge relation changed December 30 and February 10-11* 

Two rating curves used prior to February 11, well defined below 7,000 secondfeet; curve used February 11 to September 30, well defined below 5,000 

second-feet. Operation of water-stage recorder satisfactory except as noted 

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

applying to rating table mean daily gage height obtained from recorder 

graph by inspection 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 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 mean discharge. Records goodCOOPERATION. Puget Sound Power & Light Co. furnished gage-height record 

and made some discharge measurements.

mouth and 3}$ miles northeast of North Bend, King County.

DBAINAGE AREA. About 102 square miles (measured on topographic and county 

maps).

RECORDS AVAILABLE. July 4, 1907, to September 30, 1921.

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

house; installed September 26, 1916; inspected by A. R. Neth. For description of previous gages see Water-Supply Paper 512.

DISCHARGE MEASUREMENTS. Made by wading or from cable 200 yards above 

mouth.

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

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

fairly high and not subject to overflow except at extremely high stages. 

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

gage height 0.4 foot.

EXTREMES OK DISCHARGE. Maximum mean daily discharge during year; estimated 4,500 second-feet for December 30 and February 11; minimum 

stage recorded, 1.89 feet at noon August 31 (discharge, 112 second-feet).

1907-1921: 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

50 SURFACE WATER SUPPLY, 1821, PART XII A. t

SOUTH FORE OF SNOQUAIMIE BIVEB AT NORTH BEND, WASH,

LOCATION. In SE. ^ sec. 9, T. 23 N., R. 8 E., at Cooper ranch, half a mile

south of North Bend, King County, and 3^ miles, by river, above mouth. 

DKAINAGE ABE A. 84 square miles (measured on topographic maps). 

RECORDS AVAILABLE. July 21, 1907, to February 29, 1908, and June 26, 1908,

to September 30, 192i. 

GAGE. Friez water-stage recorder on left bank at Cooper ranch; installed

October 2, 1916; inspected by A. R. Neth. For description of previous

gages see Water-Supply Paper 512.

DISCHABGB MEASUREMENTS. Made by wading or from cable 150 feet below gage. 

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

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

recorder, 9.47 feet at 10 a. m. December 30 (discharge, 4,410 second-feet); 

minimum stage, from recorder, 1.79 feet at 3.15 p. m. September 17 (discharge, 128 second-feet).

1907-1921: 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 and 11, 1908 (discharge, 68 

second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed slightly December 30. Two 

rating curves well defined below 3,000 second-feet. Operation of waterstage recorder satisfactory except as noted in footnote to table of daily discharge. Daily discharge ascertained by applying to rating table mean daily 

gage height obtained from recorder graph by inspection or, for days of 

considerable variation in stage, by averaging results obtained by applying 

to rating table mean gage heights for shorter intervals. Partial clogging 

of intake pipe caused water stage in well to lag 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 mean discharge. Records good.

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

and made some discharge measurements.

LOCATION. In sec. 5, T. 32 N., E. 7 W., 1M miles above Oso and junction 

with North Fork of Stilaguamish River in Snohomish County.

DRAINAGE ABE A. 84 square miles (measured on topographic maps).

RECORDS AVAILABLE. August 11, 1917, to September 30, 1921.

GAGE. Stevens continuous water-stage recorder on left bank about 250 feet 

below mouth of 3-mile canyon; inspected by C. G. Bloxham. Datum 

lowered 0.50 foot July 24, 1920; gage heights prior to October 1, 1920, 

referred to original datum. *

DISCHARGE MEASUBEMENTS. Made by wading or from highway bridge at Oso.

CHANNEL AND CONTROL. Bed composed of boulders and gravel overlying bedrock. Banks high. One channel at all stages. Stage of zero flow, according to measurements made September 13, 1921, gage height 0.50 foot' 

±,0.25 foot.

EXTREMES OP DISCHARGE. Maximum stage during year probably occurred on 

February 11 when water-stage recorder was out of order; mean discharge 

for day estimated as 6,000 second-feet by hydrographic comparison with 

record for Sultan River. Minimum stage, from recorder, 0.89 foot August 

14-16 (discharge, 41 second-feet).

1918-1921: Maximum stage recorded, 10.05 feet December 18, 1917, from 

high-water mark in well (discharge, 9,300 second-feet); minimum stage, 

from water-stage recorder, 1.08 feet September 29 and 30, 1919 (discharge, 

27 second-feet).

ICE. Stage-discharge relation affected by ice during severe winters; flow estimated from discharge measurements, observer's notes, and weather records.

DIVERSIONS. None.

REGULATION. None.

Ac CUB ACT. Stage-discharge relation changed February 10-11; not affected by 

ice. Two rating curves well defined below 3,000 second-feet. Operation of 

water-stage recorder satisfactory except as noted in footnote to table of 

daily discharge, and except for period February to April when clogged intake pipe interfered with correct registering of low-water gage heights. 

Daily discharge ascertained by applying to rating table mean daily gage 

height obtained from recorder graph by inspection or, for days of considerable variation in stage, by averaging results obtained "by applying mean 

gage heights for shorter intervals. Records good February to April; others 

excellent except for periods when water-stage recorder was not operating.

COOPEBATION. Station maintained in cooperation with Western Power Co.

SKAGIT RIVER AT REFLECTOR BAR, NEAR MARBLEMOUNT, WASH.

LOCATION. In sec. 8, T. 37 N., R. 13 E. (unsurveyed), in Whatcom County, at 

Reflector Bar ranger station, 75 feet below mouth of Canyon Diablo, threefourths of a mile above Stetattle Creek, 1^4 miles below Thunder Creek, 

and 19 miles northeast of Marblemount, Skagit County.

DRAINAGE AREA. 1,100 square miles. Area ia United States measured on 

Washington National Forest map, edition of 1922. Area in British Columbia, 390 square miles.2

RECORDS AVAILABLE. December 6, 1913, to September 30, 1921.

GAGE. Stevens continuous water-stage recorder on right bank 75 feet below 

mouth of Canyon Diablo; installed April 13, 1914; inspected by F. E. Davis 

and employees of city of Seattle. Prior to April 13, 1914, inclined staff at 

same site but at datum 2 feet higher.

DISCHARGE MEASUREMENTS. Made from cable 50 feet below gage.

CHANNEL AND CONTROL. Control is section of stream bed from 100 to 600 feet 

below gage. Length and location of control vary with stage. Bed composed of large boulders near right bank, gravel in center, and sand and rock 

near left bank; shifts during floods. One channel at all stages. Banks not 

subject to overflow.

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

recorder, 10.7 feet at 7 a. m. June 7 (discharge, 30,800 second-feet); minimum stage recorded, 2.20 feet at 10 p. m. February 6 (discharge, 1,180 

second-feet).

1913-1921: Maximum stage, from water-stage recorder, 12.0 feet at 6.30 

p. m. December 29, 1917 (discharge, 37,300 second-feet); minimum stage,, 

from recorder, 1.64 feet from 4 p. m. November 11 to 9 p. m. November 12, 

1919 (discharge, 665 second-feet). Discharge may have been as low or 

lower on December 12, 1919, when stage-discharge relation was affected by 

ice. ,

A field investigation and office study of flood data in Skagit River basin 

indicates that a great flood occurred some time prior to 1879. High-water 

marks and other evidence seem to prove that the river reached a stage of * 

about 20 feet at Reflector Bar (discharge, about 100,000 second-feet). The 

flood of November 29-30, 1909, reached a stage of about 15.0 feet at Reflector Bar (discharge, about 58,000 second-feet). The flood of November 

18-19, 1897, was about the same as the flood of December 29-30, 1917. 

The spring floods of 1862, 1880, and 1894 probably reached nearly to the 

stage of the floods of 1897 and 1917.

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

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed at high water on May 26; not 

affected by ice. Two rating curves well defined. Operation of waterstage recorder satisfactory except that intake pipe to stilling well was partly 

clogged resulting in a lag between stage in stilling well and in river. Daily 

discharge ascertained by applying to rating table mean daily gage height 

determined from recorder graph by inspection. Records good.

COOPERATION. Station maintained in cooperation with city of Seattle.

LOCATION. In Whatcom County, a quarter of a mile above junction with Skagit 

River, 3J^ miles from Reflector Bar ranger station, and 20 miles northeast 

of Marblemount, Skagit County.

DRAINAGE AREA. 111 square miles (measured on Washington National Forest 

map, edition of 1922).

RECORDS AVAILABLE. February 15, 1919, to September 30, 1921.

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

mouth; inspected by F. E. Davis.

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

wading.

CHANNEL AND CONTROL. Control at high stage is head of falls about 200 feet 

below gage; at low stage bed of stream between gage and falls, composed 

of gravel, forms control; shifting. One channel at all stages.

EXTREMES OF DISCHARGE. Maximum stage during period of record, from waterstage recorder, 10.1 feet at midnight September 11, 1920 (discharge, 4,380 

second-feet); minimum stage, from recorder, 2.97 feet, 10 a. m. to 11 a. m. 

November 12, 1919 (discharge, 84 second-feet).

ICE. Stage-discharge relation affected by ice during extremely cold weather; 

flow estimated by means of observer's notes, weather records, and results at 

near-by gaging stations.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed July 16, 1919, and June 7, 1921; 

affected by ice December 9-18, 1919. Rating curves fairly well defined. 

Operation of water-stage recorder satisfactory except as noted in footnote to 

table of daily discharge. Daily discharge ascertained by use of discharge 

integrator except for short intervals during which diurnal fluctuation was 

small, for which it was ascertained by applying to rating table mean daily 

gage height determined from recorder graph by inspection. Records good.

COOPERATION. Station maintained in cooperation with city of Seattle.

SOUTH FORK OF SAUK RIVER NEAR BARLOW PASS, WASH.

LOCATION. In NE. M sec. 27, T. 30 N., R. 11 E., 2% miles above junction 

with North Fork and 5 miles northeast of Barlow Pass, Snohomish CountyDRAINAGE AREA. 32.7 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 1, 1917, to February 8, 1921, and August 20 

to October 16, 1921, when station was discontinued.

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

Nicolai Aall.

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

CHANNEL AND CONTROL. Bed composed of boulders and gravel. One channel 

at all stages. Principal control 100 feet below gage.

EXTREMES OF DISCHARGE. Maximum stage during periods October 1, 1920, to 

February 8,1921, and August 20 to October 16,1921, from water-stage recorder, 

6.5 feet at 2.30 a. m. October 4,1920 (discharge, 3,140 second-feet); minimum 

stage from recorder, 2.07 feet December 26i27 (discharge, 43 second-feet). 

1918-1921: Maximum stage recorded, 9.1 feet at 1.30 a. m. December 

29, 1917 (discharge, 5,800 second-feet); minimum stage, from recorder, 1.86 

feet at 7 p. m. October 20, 1919 (discharge, 35 second-feet); may have been 

lower in December, 1919.

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

rating curve assumed applicable.

DIVERSIONS. None.

REGULATION. None.

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

curve fairly well denned between 100 and 2,000 second-feet; extended to 

extremely high stages by study of flood peak discharge at all gaging stations 

on Sauk and Skagit rivers. Operation of water-stage recorder satisfactory 

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

height determined from recorder graph by inspection or, for days of considerable variation in stage, by averaging results obtained by applying mean 

gage heights for shorter intervals. Records good.

COOPEBATION. Station maintained in cooperation with American Nitrogen* 

Products Co.

68 SURFACE WATER SUPPLY, 1921, PAKT XII A.

WHITECHUCK RIVER NEAR DARRINGTON, WASH.

LOCATION. In NW. M sec. 10, T. 31 N., R. 11 E., at 4.5-mile post, 4^ miles 

above junction with Sauk River and 11 miles southeast of Darrington* 

Snohomish County.

DKAINAGE ABEA. 75 square miles (measured on topographic maps).

RECOUPS AVAILABLE. October 19, 1919, to December 12, 1921, when station 

was discontinued. Records fragmentary.

GAGE. Stevens continuous water-stage recorder on l^ft bank; installed August 

19, 1919; inspected by N. A. and B. L. Aall and J. J. Gallivan.

DISCHABGE MEASUREMENTS. Made from cable 300 feet below gage or by wading 

near gage.

CHANNEL AND CONTBOL. Control is heavy boulder riffle just below gage; practically permanent. Banks high and wooded. One channel at all stages.

EXTREMES OF DISCHABGE. Maximum stage during period of record, from waterstage recorder, 6.4 feet about noon December 12, 1921, when recorder installation was damaged and record terminated (discharge, 4,540 sacond-feet); 

minimum Stage recorded, 0.9 foot sometime between November 4 and 14, 

1919, when recorder was not operating properly and for which period graph 

is not interpretable in regard to time (discharge, 111 second-feet); probably 

lower discharge in December, 1919, when recorder was not operating.

ICE. Stage-discharge relation not affected by ice during periods of record.

DIVEBSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed by fallen trees on control November 15, 1919; on September 15, 1920, the trees were washed from control and 

stage and discharge reverted to original relationship. Rating curves fairly 

well defined below 1,200 second-feet; extended above that point. Operation 

of water-stage recorder satisfactory except as noted in footnote to table of 

daily discharge. Daily discharge ascertained by applying to rating table 

.mean daily gage height obtained from recorder graph by inspection or, for 

days of considerable range in stage, by averaging results obtained by applying to rating table mean gage heights for shorter intervals. Records good 

except those for extremely high water and those estimated.

COOPERATION. Part of gage-height record furnished by American Nitrogen 

Products Co.

Water-Supply Paper 512.

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. Right bank high 

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

11-foot stage.

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

recorder, 9.7 feet midnight to 2 a. m. October 4 (discharge, 18,700 secondfeet) ; minimum stage, from recorder, 2.68 feet at 4 a. m. November 13 (discharge, 649 second-feet).

1910-1921: Maximum stage recorded, 13.7 feet at 12.30 p. m. December 

29, 1917 (discharge, 36,800 second-feet); minimum stage recorded, 1.21 feet 

December 15-16,1919 (discharge, 219 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

RE GULATION . None.

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

between 700 and 10,000 second-feet. Operation of water-stage recorder 

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

discharge ascertained by applying to rating table daily mean gage height determined from recorder graph by inspection or, for a few days when range 

of stage was considerable, by averaging results obtained by applying mean 

gage heights for shorter intervals. Records excellent except for extremely 

high stages.

COOPERATION. Station maintained in cooperation with United States Forest 

Service.

74 SURFACE WATER SUPPLY, 1921, PART XII A.

NOOKSACK EIVER BASIN. 

NOOKSACK HIVER AT EXCE1SIOB, WASH.

LOCATION. In sec. 31, T. 40 N., R. 8 E. (unsurveyed), at highway bridge 600 

feet below Nooksack Falls (Excelsior) power plant, half a mile below Wells 

Creek, and 6 miles east of Glacier, in Whatcom County.

DRAINAGE AREA. 96 square miles (measured on topographic maps).

RECORDS AVAILABLE. August 25, 1920, to September 30, 1921, when station 

was discontinued.

GAGE. Vertical staff in two sections on downstream end of right abutment; 

read by Mrs. H. E. Barnes.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of small boulders and gravel. Channel 

fairly straight for 600 feet above gage; curves below. Banks high and not 

subject to overflow. Riffle control, 100 feet below gage; likely to shift at 

extreme high water. Current swift.

EXTREMES OF DISCHARGE. Maximum stage recorded during period of record, 

5.4 feet at 3.45 p. m. October 4 (discharge, 4,650 second-feet); minimum 

stage recorded, 0.40 foot February 5-9 (discharge, 186 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. At extreme low water the entire flow above Nooksack Falls, 

half a mile aboVe gage, is diverted through the power plant and returned to 

river 600 feet above gage. Wells Creek, which enters river just below falls, 

is not diverted.

REGULATION. Pondage above diversion dam is too slight to affect flow appreciably.

ACCURACY. Stage-discharge relation changed October 4. Two rating curves 

fairly Well defined. Gage read to hundredths once daily. Daily discharge 

ascertained by applying daily gage height to rating table. Records good.

76 SURFACE WATEB SUPPLY, 1921, PAET XII A.

MIDDLE FORK OF NOOKSACK RIVER NEAR DEMING, WASH.

LOCATION. In NW. % sec. 13, T. 38 N., R. 5 E., at highway bridge just below 

mouth of Heisler's Creek, 5| miles southeast of Deming, Whatcom County, 

and 4 miles above mouth..

DRAINAGE ABBA. 72 square miles (measured on topographic maps).

RECORDS AVAILABLE. August 28, 1920, to September 30, 1921, when station 

was discontinued. October 10, 1910, to March 14, 1911, fragmentary gageheight record.

GAGE. Vertical staff in two sections, on downstream end of right abutment; 

read by F. F. Filbert. October 10, 1910, to March 14, 1911, vertical staff 

in two sections 75 feet below present gage.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of small boulders and sand. Gontro 

is small boulder riffle 150 feet below gage; sensitive for low stages.

EXTREMES OF DISCHARGE. Maximum mean daily discharge during period August 

28, 1920, to September 30, 1921, 7,500 second-feet on October 4; estimated 

by hydrographic comparison with records for Nooksack River at Excelsior 

and Baker River below Anderson Creek.. Minimum stage recorded, 1.22 

feet November 13 (discharge, 195 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed October 4, 1920, and gradually 

over the period June 28 to September 8, 1921. Standard rating curve 

fairly well defined; used August 28 to October 4, 1920. Two parallel 

curves used, applicable October 4, 1920, to June 27, 1921, and September 

9-30, 1921. Shifting-control method used June 28 to September 8, 1921. 

Gage read once a. day to hundredths four or five times a week; single reading daily during summer may not represent mean daily stage owing to diurnal 

fluctuation caused by glacial run-off. Daily discharge ascertained by 

applying daily gage height to rating table or, for days when gage was not 

read, by interpolating or estimating on basis of comparison with flow of 

near-by streams. Records fair.

RECORDS AVAILABLE. Flood heights only, at Wenatchee, 1894 to 1903; continuous gage-height record at Wenatchee, April 18, 1904, to December 31, 1916; 

at Beverly January 1-13, 1917; at Vernita, January 14, 1917, to September 

30, 1921; daily discharge ascertained from May 1, 1913, to September 30, 

1921. Gage-height record at Wenatchee published by United States 

Weather Bureau.

GAGE. Since March 25, 1918, vertical staff gage in eight sections, on right bank 

at ferry; read by J. P. Richmond. For history of previous gages see WaterSupply Paper 512. All gage readings at Vernita refer to same datum, 388.7 

feet above sea level. Gages at Wenatchee read by Weather Bureau observers.

DISCHARGE MEASUREMENTS. Made from standard gaging car on ferry cable at 

Vernita or, when ice conditions are severe, from railroad bridge at Beverly.

CHANNEL AND CONTROL. Bed composed of gravel and boulders. High-water 

control, Coyote Rapids 6 or 7 miles below gage; low-water control, riffle 

noticeable at low stages, about three-fourths of a mile below gage; apparently permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 31.3 feet 

June 11 (discharge, 484,000 second-feet); Minimum stage recorded, 2.60 

feet at 8.30 a. m. February 11 (discharge, 41,200 second-feet).

1913-1921: Maximum stage recorded, 45.7 feet at Wenatchee, June 15 

and 16, 1913 (discharge, 528,000 second-feet); minimum discharge, 23,900 

second-feet (current-meter^ measurements) January 31, 1917, and December 

14j"I§i^, When ^itage-discnarge relation was affected by ice.

Maximum stage recorded at Wenatchee by United States Weather 

Bureau and Great Northern Railway Company, 58.0 feet June 7, 1894 

(discharge estimated, by extending rating curve, 710,000 second-feet). 

The Chief of Engineers, United States Army,8 gives a crest elevation of the 

1894 flood and an elevation of zero of the Weather Bureau gage, from which 

it appears that the gage height was 59.8 feet (discharge estimated, by extending rating curve, 740,000 second-feet).

ICE. Stage-discharge relation affected by ice except during mild winters. Flow 

estimated from gage-height record, discharge measurements, observer's 

notes, and weather records.

DIVERSIONS. Some water diverted for irrigation.

REGULATION. None.

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

curve well defined. Gage read to hundredths twice daily. Daily discharge 

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

excellent.

COOPERATION. Maintained in cooperation with Washington Irrigation and 

Co.

The following discharge measurement was made by R. B. Kilgore: 

February 23: Gage height, 5.50 feet; discharge, 63,200 second-feet.

LOCATION. In sec. 3, T. 30 N., R. 31 W,, at highway bridge opposite Great 

Northern Railway station at Libby, Lincoln County.

DRAINAGE ABBA. 11,000 square miles.

RECORDS AVAILABLE. October 13, 1910, to September 30, 1921.

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

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

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

to change reduced to new datum.

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

bridge, from ferry cable.

CHANNEL AND CONTROL. Channel broken by two piers! Bed of stream composed of small rocks; probably permanent. Current fairly swift and«uniformly distributed.

EXTREMES OF DISCHARGE. Maximum stage reported during years ending 

September 30, 1920 and 1921, 13.84 feet June 9, 1921 (discharge, 72,900 

second-feet); minimum stage, 1.88 feet November 14, 1920 (discharge, 2,300 

second-feet).

1910-1921: Maximum stage, 19.17 feet June 21, 1916 (discharge, 130,000 

second-feet); minimum stage, 1.4 feet February 7, 1914 (discharge, 1,480 

second-feet).

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. None of importance.

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

rating curve used during period; well defined between 2,500 and 40,000 

second-feet and fairly well defined above 40,000 second-feet; discharge 

measurements made during 1922 indicate that curve is applicable for 1921. 

Gage read to hundredths once daily except Sundays and holidays. Daily 

discharge ascertained by applying daily gage height to rating table except 

as noted in footnote to tables of daily discharge. Records good.

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

No discharge measurements were made at this station during the year.

Railway, Bonner County, 3^ miles below Round Prairie, and 12 miles 

above mouth.

DRAINAGE AREA. 717 square miles. (Area in United States measured on map 

issued by United States Geological Survey, scale 1:250,000; area in British 

Columbia measured on Cranbrook sheet, British Columbia map.)

RECORDS AVAILABLE. February 21, 1912, to September 30, 1916, and March 1, 

1919, to September 30, 1921, at present site; March 10, 1911, to February 

20, 1912, at railway bridge 1 mile downstream.

GAGE. Vertical staff and inclined staff on left bank, 150 feet west of Snyder 

ranger station; installed October 21, 1919; read by W. O. Blackman. For 

description of previous gages see Water-Supply Paper 512.

DISCHARGE MEASUREMENTS. Made by wading or from cable near gage. Highwater measurements formerly made from highway bridge a quarter of a 

mile downstream.

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

steep. Channel straight above and below gage. Banks high and not subject to overflow. Riffle control 500 feet below gage; shifting at high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 9.0 feet at 

7 a. m. May 26 (discharge, 7,230 second-feet); minimum stage recorded, 

2.98 feet September 8, 13, and 14 (discharge, 92 second-feet).

1911-1916, 1919-1921: Maximum stage recorded, 11.0 feet at 4 p. m. 

June 19, 1916 (discharge, 10,800 second-feet); minimum stage recorded, 

2.80 feet October 25 and 26, 1919 (discharge, 56 second-feet). Discharge

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

observer's notes and weather records.

ACCURACY. Stage-discharge relation changed May 25-26; not affected by ice.

Two rating curves fairly well defined below 3,000 second-feet. Gage read

to hundredths twice daily. Daily discharge ascertained by applying mean

daily gage height to rating table except as noted in footnote to table of

. daily discharge. Records good.

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

Plains, Sanders County, and 7 miles below mouth of Flathead River.

DRAINAGE ABBA. 19,900 square miles.

RECORDS AVAILABLE. October 28, 1910, to September 30, 1921.

GAGE. Barrett & Lawrence water-stage recorder, installed November 28, 1911, 

on right bank, 50 feet below an overhanging chain gage, 150 feet below site 

of old ferry; datum same as that of chain gage which was read prior to 

installation of water-stage recorder. Recorder inspected by A. L. Steiner.
90 SUKFACE WATER SUPPLY, 1921, PAET XII A.

DISCHARGE MEASUREMENTS. Made from cable installed April 26, 1917, at site 

of old ferry cable used prior to July 29, 1913. July 29, 1913, to April 25, 

1917, measurements were made from highway bridge at Plains, 3 miles 

below.

CHANNEL AND CONTROL. River deep and current only moderately swift even 

at flood stages. Banks high and not subject to overflow. Bed practically 

permanent. No well-defined control.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 16.0 feet at 

10 p. m. May 28 (discharge, 100,000 second-feet); minimum stage recorded, 

4.3 feet February 11 and September 16-18 (discharge, 7,010 second-feet). 

1910-1921: Maximum stage recorded, 17.9 feet June 5, 1913, and July 2, 

1916 (discharge, 115,000 second-feet); minimum stage recorded, 3.7 feet 

several times during October and November, 1919 (discharge, 4,890 secondfeet); lower flow probably occurred during whiter of 1919-20.

ICE. Stage-discharge relation seriously affected by ice at times.

DIVERSIONS. Numerous diversions for irrigation from headwaters of Clark 

Fork and tributaries to Flathead river.

for part of flow.

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

curve well defined below and fairly well defined above 60,000 second-feet. 

Mean daily gage height obtained from recorder graph by inspection. Daily 

discharge ascertained by applying mean daily gage height to rating table 

except for period June 12-19, when gage-height record was in error, for 

which it was ascertained by combining flow of Flathead River near Poison 

and Clark Fork at St. Regis. Records good.

No discharge measurements were made at this station during the year.

CLARK FORK AT NEWPORT, WASH.

LOCATION. In SW. M sec. 24, T. 56 N., E. 6 W. Boise meridian, in Bonner 

County, Idaho, one-eighth of a mile from Washington-Idaho State boundary 

at Newport, Pend Oreille County, Wash. Supplemental data obtained at 

Priest River, Idaho, and Metaline Falls, Wash.

DRAINAGE AREA. 24,200 square miles (area in United, States measured on 

maps issued by United States Geological Survey, scale 1:500,000; area of 

Flathead River basin in British Columbia measured on Department of 

Lands map, scale 1:1,125,000; area of Priest River basin in British.Columbia 

measured on Nelson sheet, British Columbia sheet maps, scale, 1:120,720). 

Drainage area at Priest River, Idaho, practfcally~samea's &t Newport; area 

at Metaline Falls, 25,100 square miles.

RECOEDS AVAILABLE. June 26, 1903, to September 30, 1921, as follows: Priest 

River, Idaho, June 26, 1903, to April 30, 1905; Newport, Wash., April 16, 

1904, to September 30, 1921, except during most of the winter months; and 

Metaline Falls, Wash., November 4, 1908, to September 4, 1910, January 1 to 

November 28,1911, and December 22, 1911, to September 30,1921. During 

periods when records were obtained simultaneously, computed results at 

the different locations were compared, and those shown to be the most 

reliable were chosen. Daily discharge records given below cover the period 

June 26, 1903, to November 30, 1912, and supersede records previously 

published in Water-Supply Papers 135 (p. 40), 178 (p. 15), 252 (p. 85), 

272 (p. 73), and 292 (p. 65). Monthly discharge only has been determined 

for the Newport station subsequent to November 30, 1912, but a continuous 

record of daily discharge is available for the Metaline Falls station.
T7PPEE COLUMBIA EIVEK BASIN. 93

GAGES. At Priest River., Idaho: Wire gage, anchored to a platform on right 

side of river, 1,000 feet west of Great Northern Railway station. Zero of 

gage at elevation 2,005.39 feet.4

At Newport, Wash.: Vertical staff in four sections on left side of river, 

attached to middle one of three docks formerly operated by Pend Oreille 

River Navigation Co. JJero of gage at elevation 2,031.98 feet.4 Since 

April 5, 1916, at ferry landing one-fourth of a mile upstream; datum 0.13 

foot higher to make readings comparable to those made on old gage.

At Metaline Falls, Wash.; Vertical and inclined staff gages at different 

locations and with varying datum (see description, Water-Supply Paper 

462, p. 70). "

DISCHARGE MEASUREMENTS. Made from ferries, boats, ice cover, or cable. 

Measurements at Metaline Falls reduced^by estimated inflow between 

Newport and measuring section. * ''

CHANNEL AND CONTROL. At Priest River, Idaho: Low-water control composed 

of heavy angular boulders in a stretch of the channel extending some distance downstream from gage; high-water control formed by Albany Falls, 

4% miles below gage; both controls permanent.

At Newport, Wash.: Low-water control, 1,600 feet below gage,, composed 

of sand and gravel in two channels separated by an island; rather unstable; 

permanent extreme high-water control formed by a narrow, rocky, and 

constricted channel at Box Canyon 53 miles below gage..

At Metaline Falls, Wash,: Permanent control for all stages forced by 

Metaline Falls the drop over which is 20 feet in a distance qf, ; 1,200 feet.

EXTREMES OF DISCHARGE. Maximum discharge during year, 109,000 secondfeet, June 14; minimum discharge, 9,060 second-feet, .September 28 and 29. 

1903-1921: Maximum discharge, 136,000 second-feet, June 15, 1913; 

minimum discharge, 2,200 second-feet, December 12, 1919.

Flood at Newport during June, 1894, reached a stage of 38^.9 feet, as 

determined independently from three separate high-water marks (discharge, 

217,000 second-feet, estimated by extending rating curve).

ICE. Stage-discharge relation at Priest River and Newport affected by ice for 

short periods during severe winters; not affected by ice at Metaline Falls.

DIVERSIONS. Numerous small diversions from upper tributaries for irrigation.

REGULATION. Flathead, Pend Oreille, and Priest lakes furnish natural but uncontrolled regulation.

ACCURACY. Stage-discharge relation permanent at Priest River, where records 

were obtained prior to April 30, 1905; no ice effect. Rating curve well 

defined throughout. Gage read to hundredths once daily. Daily discharge 

ascertained by applying daily gage height t6 rating table.

For the periods May 1, 1905; to November 30, l^, March 1 to October 

7,19071, 'March 1 to November 30,1908, March 1 to April'30, 1909, August 1, 

1910, to January 31, 1911, September JL-30, 1911, and Deceixibdr £ 1911, to 

November 30, 1912, daily discharge was determined from gage-height record 

obtained and rating curves developed at.Newport. Stage-discharge relation 

changed at high water on June 1,6, 1908, and may have changed several 

times fqr low and medium stages'but such charEges are indeterminate; 

affected by ice during January, 1912. Rating curve applicable prior to June 

16, 1908, developed by means of a relationship curve ^between Priest River 

and Newport gages, is well defined; curve used subsequent to June 16, 1908, 

developed by correcting discharge at MetaKne Falls for inflow, and. referring 

the result to simultaneous gage reading at Newport^ well defined. ;Gage 

redd to tenths once daily. Daily discharge ascertained by" applying daily 

gage height to rating table,, .except'for January, 1912, for whieh it was 

ascertained as explained below.

* Not referred to II. S. Coast ami Geodetic Stitvey datum. Elevation of bench marks to'which gages 

were referred, obtained from II. S. Geol. Survey Bulletin 567. o *;
94 SUBFACE WATEK SUPPLY, 1921, PART XII A.

For the periods December 1, 1906, to February 28, 1907, October 8, 1907, 

to February 29, 1908, and January 1-31, 1912, for which gage-height records 

are not available or, if available, appear to be in error, meaa discharge 

was determined as follows: Mean discharge of Columbia River at The 

Dalles, Oreg., for each month during the period August, 1904, to April, 

1913, was reduced by the combined mean discharge for the corresponding 

month of Deschutes, John Day, Umatilla, Snake, Yakima, Wenatchee, 

Chelan, Methow, and Spokane rivers. Likewise, for the period May, 1913, 

to September, 1921, monthly mean discharge of Columbia River at Wenatchee or Vernita, Washington, was reduced by the combined mean discharge, for the corresponding month, of Wenatchee, Chelan, Methow, and 

Spokane rivers. The results,for the entire period August, 1904, to September, 

1921, determined by these'two processes, will be referred to hereinafter as 

discharge of "Columbia less tributaries." Computed monthly discharge of 

Clark Fork at Newport and at Metaline Falls was compared with monthly 

discharge of "Columbia less tributaries" to determine ratios for as many 

months of the entire period as possible, from which an average ratio for 

each month of the year was derived. Then mean monthly discharge for 

the periods named at the beginning of this paragraph were obtained by multiplying the mean monthly discharge of "Columbia less tributaries" by the 

 average ratio for the corresponding month.

For the periods November 1-30, 1908, March 1 to November 30, 1909, 

March 1 to August 31, 1910, January 1 to October 31, 1911, and October 1 

to November 30, 1912, simultaneous discharge was computed for the Newport and Metaline Falls stations. During these periods of simultaneous 

discharge two sets of monthly ratios, based on discharge of " Columbia less 

tributaries," had been computed and used in deriving the average ratio 

for each month of the year, as explained in the preceding paragraph. Those 

ratios which more nearly agreed with the average ratio for the corresponding 

month were accepted as an index of the -more accurate record. This com 

parison indicated that results'at the Metaline Falls station were the more 

accurate for the periods May 1 to November 30, 1909, March 1 to July 31, 

1910, February 1 to August 31, 1911, and October 1-31, 1911. Except 

for November 1-30, 1911, when the average of the simultaneous results was 

accepted as being correct, the discharge for the Newport station was judged 

to be the more accurate for the remaining months of the periods, mentioned 

at the beginning of this paragraph.

For the peripd December 1, 1912,, to September 30, 1921, except for 

winter months, simultaneous records are also available at Newport and 

Metaline Falls. The daily discharge, however, as previously published for 

Metaline Falls station is considered very reliable. The drainage area at 

Metaline Falls is only 3.7 per cent larger than at Newport and the difference 

in discharge, is probably less than 3 per cent. Therefore, daily discharge 

at Newport is not published here, but monthly discharge tables appear 

below. The rating curve used for the above period, giving discharge at 

Newport but referred to gage heights at Metaline Fall?, is well defined by 

numerous measurements made at Metaline Falls gaging station, the results 

of which have been published in previous water-supply papers. The discharge as published for these measurements was reduced, to correct for inflow, 

by three times the flow of Sullivan Creek and then plotted to Metaline 

Falls gage heights, The corrections for inflow, made in thi$ manner, represent an average of 2.2 per cent of the flow at Newport,

Records excellent, 1903 to 1905 and 1913 to 1921; good, 1906 and 1912; 

and fair, 1907 to 1911.

1912-1921: Maximum stage recorded, 4.2 feet June 2, 1913 (discharge, 

1,650 second-feet); minimum stage recorded, 1.10 feet on March 25, 1919 

(discharge, 46 second-feet).

ICE. Stage-discharge relation affected by ice only during extremely severe 

winters.

DIVERSIONS. Water is diverted from Sullivan Creek about 1 mile above station 

for storage in Sullivan Lake, but entire run-off of drainage basin passes gage.

REGULATION. Storage in Sullivan Lake is used by Inland Portland Cement Co. 

to increase low-water flow.

ACCURACY. Stage-discharge relation for medium and high stages changed 

June 8; not affected by ice. Rating curve used prior to change fairly well 

defined below 1,000 second-feet; curve used after change fairly well defined 

below 1,500 second-feet. Gage read to hundredths once daily; difficult to 

read gage accurately owing to surge. Daily discharge ascertained by 

applying daily gage height to rating table. Records good.

COOPERATION. Station maintained in cooperation with United States Forest 

Service and Inland Portland Cement Co.

SPOKANE RIVER AT POST FAL1S, IDAHO.

LOCATION. In sec. 4, T. 50 N., R. 5 W. Boise meridian, a quarter of a mile 

below power plant of Washington Water Power Co., three-fourths of a 

mile below intake of Spokane Valley Land & Water Co.'s canal, and 1 mile 

west of Post Falls, Kootenai County.

DRAINAGE AREA. 3,880 square miles (measured by engineers of Washington 

Water Power Co. on maps compiled from best information available).

RECORDS AVAILABLE. January 1, 1913, to September 30, 1921.

GAGE. Stevens continuous water-stage recorder since November 22, 1920; 

inspected by employees of Washington Water Power Co. Previous gage 

vertical staff in three sections on left bank; read by Nils Lindberg and 

Grant Merrill. Elevation of zero of gage, 2,000 feet above sea level.

DISCHARGE MEASUREMENTS. Made from cable 300 feet below gage.

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

during floods. One channel at all stages.

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

recorder, 74.30 feet, probably on May 21 (discharge, 25,900 second-feet); 

minimum stage, from recorder, 65.80 feet at 5.20 a. m. September 12 (discharge, 820 second-feet).

1911-1921: Maximum stage recorded, 79.20 feet at 7.30 a. m. May 18, 

1917 (discharge, 39,800 second-feet); minimum stage recorded on September 12, 1921.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Spokane Valley Land & Water Co.'s canal diverts water above 

gage for irrigation. Mean diversion during 1921, 68 second-feet. Storage 

in Coeur d'Alene Lake partly regulated by operation of gates in dam at 

Post Falls.

REGULATION. Varying load on power plant causes fluctuation in stage. Flow 

partly regulated by storage in Coeur d'Alene Lake.
UPPER COLUMBIA RIVER BASIN. 131

ACCURACY. Stage-discharge relation changed with change of gages on November 

22. Two rating curves well denned. Staff gage read to hundredths once 

daily until November 21; thereafter water-stage recorder operated satisfactorily except as noted in footnote to table of daily discharge. When 

discharge is less than 5,000 second-feet, stage is variable owing to changing 

load at power plant, and one gage reading daily may not indicate true mean 

stage. Daily discharge prior to November 22, ascertained by applying 

daily gage height to rating table; after November 21, by applying to rating 

table mean daily gage height determined from recorder graph by inspection or, for discharge below 10,000 second-feet, by use of discharge integrator. 

Records good prior to November 21; excellent thereafter.

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

Discharge measurements of Spokane River at Post Falls, Idaho, during the year

ending Sept. SO, 1921.

SPOKANE RIVER AT SPOKANE, WASH.

LOCATION. In sec. 13, T. 25 N., R. 42 E., about opposite Cochrane Street, 

Spokane, Spokane County, one-fourth of a mile above high railroad viaduct 

and 3 miles above Latah Creek.

DRAINAGE AREA. 4,350 square miles (measured by engineers of Washington 

Water Power Co. on maps compiled from best information available).

RECORDS AVAILABLE. April 1, 1891, to September 30, 1921.

GAGE. Stevens continuous water-stage recorder, referred to mean sea level as a 

datum, on right bank at Cochrane Street about 1 mile, below Monroe Street 

bridge; installed May 9, 1921, and used since July 1,1921. Gages previously 

used as follows: April 1, 1891, to October 24, 1896, vertical staff gage near 

head gates at Washington Water Power Co.'s dam above Spokane Falls, 1 

mile above present site; zero of this gage at same elevation as crest of dam. 

October 25, 1896, to July 8, 1903, two wire gages at Oregon Railroad & Navigation Co.'s bridge, .2.9 miles above present site. July 9, 1903, to April 9, 

1904, a wire gage on Olive Avenue Bridge, 2.7 miles above present site; at 

different datum but set to read same as previous gage. Manet 31, 1904r to 

March 1, 1907, vertical staff at Mission Street bridge, 3.4 miles above 

present site. March 2, 1907, to July 23, 1911, combined inclined and ver*

',, tical staff gage at Martha Street, 4.0 miles above present site. July 24,1911, 

to July 30, 1915, several gages, set to mean sea level datum, located 500 fe4t 

above Washington Water Power Co.'s steam plant, 3.8 miles above present 

site; Bristol water-stage recorder in operation for most of'this period. July 

31,1915, to June 30, 1921, Stevens continuous water-stage recorder, referred 

to mean sea level as a datum, at same location near Washington Water Power 

Co.'s steam plant. At time of each relocation simultaneous readings were 

obtained between old and new gages so that the relation of stage at the 

different sites was established.

DISCHARGE MEASUREMENTS. Made from cable at gage. Measurements, 1896 to 

1900, republished in this report were made from Oregon Railroad & Navigation Co.'s bridge, 2.9 miles upstream.

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

all stages. Control is well-defined riffle a quarter of a mile below gage; 

should be permanent. Stage of zero flow, estimated at gage height 14.5 feet, 

on October 7, 1922.
UPPEB COLUMBIA RIVER BASIN.. 13B

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 

1921, from water-stage recorder near steam plant, 79.8 feet May 21 and 22 

(discharge, 26,200 second-feet); minimum stage, from recorder at Cochrane 

Street, 17.64 feet at 7 a. m. July 21 (discharge, 1,310 second-feet).

1891-1921: Maximum stage recorded, 12.42 feet (on gage at dam above 

Spokane Falls) May 31, 1894 (discharge, 49,000 s second-feet); minimum 

stage recorded, 1.3 feet (Martha Street gage) September 28-30, 1905 (discharge, 1,240 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Water is diverted above station for irrigation by Spokane Valley 

Land & Water Co.

REGULATION. Flow partly regulated by storage in Coeur d'Alene Lake since 

July, 1906.

ACCURACY. During the year ending September 30,1921, stage-discharge relation 

changed with change of gages, June 30 to July 1. Rating curve used prior to 

change well defined; curve used after change fairly well defined. Operation 

of water-stage recorder satisfactory at both locations. Daily discharge 

October 1 to March 18 and for a few days in June ascertained by means of 

the discharge integrator; for remainder of year by applying to rating table 

mean daily gage height determined from recorder graph by inspection. 

Records excellent to June 30; good thereafter.

Discharge April 1, 1891, to March 31,1904, revised in this report, owing to 

(1) an error made in original computations covering the period prior to 

October 25,1896, (2) rating curve used originally did not average low-water 

measurements, and (3) soundings of the early measurements were inconsistent. Stage-discharge relation fairly permanent during period. Rating 

curves fairly well defined. Daily discharge ascertained by applying mean 

daily gage height to rating table. Prior to October 25, 1896, gage readings 

during the low-water season were corrected for regulation of gates at either 

end of dam and for operation of flashboards. The corrections applied are of 

doubtful accuracy, and publication of daily discharge is not considered 

justifiable., Records prior to October 25, 1896, poor; thereafter, good.

NOTE. Original discharge computations for measurements made during the period 1896 to 1900, revised 

owing to inconsistencies in soundings; in recomputing these measurements all soundings ,were corrected to 

a standard cross section. Qage heights shown for measurements made during period Oct. 6, 1920, to Sept. 

30, 1921, were read on gage at steam plant; for several of the measurements the gage at Cochrane Street 

was read, as follows: May 17, 24.98 feet; May 19, 25.20 feet; May 24, 25.11 feet; June 6, 23.63 feet; June 13, 

22.62 feet (first measurement) and 22.58 feet (second measurement); June 20, 20.43 feet; June 29,19.00 feet; 

July 19,17.96 feet (first measurement); Sept. 10,17.76 feet (first measurement); Sept. 12, 17.74 feet (second 

measurement); Sept. 30,17.87 feet (second measurement).

NOTE. Records in the above tables for the period April, 1891, to December, 1896, supersede records 

previously published in Water-Supply Paper 272, pp. 130-131. Records for the period October, 1896, to 

March,-1904, supersede records previously published in the eighteenth to twenty-second annual reports 

of the United States Geological Survey, and in water-supply papers 75, 85,100, and 135. Results for the 

period April to September, 1904, are the same as those published in Water-Supply Paper 135, p. 51, except 

that they have been reduced to three signiacant.figures.

Monthly discharge in second-feet per square mile and run-off in inches for year ending Sept. 30,1921, 

not published owing to regulation. Yearly figures represent the natural discharge and run-off quite closely.
142 SUBFACE WATER SUPPLY, 1921, PART XII A.

SPOEANE RIVER BELOW 1ITTIE FALLS, NEAR LONG LAKE, WASH.

LOCATION. In NW. M sec. 19, T. 27 N., R. 39 E., just above Chamokane Ferry, 

1^ miles below Little Falls power plant of Washington Water Power Co., 

4 miles below Chamokane Creek, and 5 miles below Long Lake, Lincoln 

County.

DRAINAGE: AREA. 6,380 square miles (measured by engineers of Washington 

Water Power Co. on map compiled from best information available.

RECORDS AVAILABLE. November 5, 1912, to September 20, 1921.

GAGE. Stevens continuous water-stage recorder on left bank; 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. Banks high; one channel at all stages. No noticeable riffle control 

below gage.

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

recorder, 87.0 feet at 9 p. m. May 21 (discharge, 29,300 second-feet). Minimum mean daily discharge, 1,870 second-feet on August 21 when intake to 

stilling well was closed; determined by means of a curve of relation between 

gage at station and tailrace gage at Little Falls power plant.

1912-1921: Maximum stage, from water-stage recorder, 90.32 feet at 

8.30 p. m. May 18, 1917 (discharge, 41,300 second-feet). Minimum mean 

daily discharge, 1,720 second-feet September 15, 1918; minimum discharge 

lower when water was below intake for parts of many days during lowwater seasons.

ICE. Stage-discharge relation not affected by ice.

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

irrigation above station.

REGULATIONS. 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 permanent. Rating curve well defined. 

Operation of water-stage recorder satisfactory except as noted in footnote 

to table of daily discharge. Daily discharge ascertained by use of discharge 

integrator, by applying to rating table mean daily gage height determined 

from recorder graph by inspection, or, during periods of faulty operation 

of recorder, by applying to rating table mean daily gage height determined 

from readings on gage in tailrace of Little Falls power plant, by means of 

curve of relation between that gage and station gage. Records excellent 

except for period July 11 to September 16, for which they are good.

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

furnished by Washington Water Power Co.

144 SUEFACE WATEB SUPPLY, 1921, PART,XII A.

ST. JOE RIVER AT CAXDEK, IDAHO.

LOCATION. In sec. 3, T. 45 N., R. 2 E. Boise meridian, at ferry 150 feet southwest of Chicago, Milwaukee & St. Paul Railway station at Calder, Shoshone 

County, 5 miles below Marble Creek, and 11 miles east of St. Joe.

DRAINAGE AREA. 1,080 square miles (measured by engineers of Washington 

Water Power Co. on map compiled from best information available).

RECORDS AVAILABLE. July 13, 1920, to September 30,1921. April 14,1911, to 

September 30, 1912, at station about 2J^ miles downstream

GAGE. Stevens continuous water-stage recorder on right bank at ferry landing; 

installed December 22,1920; inspected by C. P. Latham. July 13 to December 21, 1920, vertical staff gage at practically same site and at same datum. 

Elevation of gage datum about 2,100 feet above sea level.

DISCHARGE MEASUREMENTS. Made from cable or by wading.

CHANNEL AND CONTROL. Right bank high; not subject to overflow; left bank 

subject to overflow at high stages. Shifting gravel riffle 800 feet below gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 87.5 feet 4 

a. m. to 9 a. m. May 8 (discharge, 17,400 second-feet); minimum stage 

recorded, 79.41 feet at 5 p. m. August 28 (discharge, 390 second-feet).

1911-1912; 1920-1921: Maximum stage recorded on May 8, 1921; minimum stafee, 1.6 feet (old station) November 2, 1911 (discharge, 380 secondfeet).

ICE. Stage-discharge relation Seriously affected by ice at times.

DIVERSIONS. None.

REGULATION. Flash dam at Marble Creek used to store water for flushing logs 

down river during low water. Water released twice daily during summer 

and once daily in early autumn. Operation of dam causes diurnal fluctuation at gage of at least 1 foot. Duration of effect about 4 hours.

ACCURACY. Stage-discharge relation changed November 21; not affected by ice. 

Rating curve used prior to change, well defined below 2,000 second-feet; 

curve used subsequent to change, well defined. Staff gage read to tenths 

twice daily prior to installation of waters-stage recorder on December 22. 

Owing to incomplete intake of well and damaged staff gage, operation of 

water-stage recorder was not wholly satisfactory during several periods. 

Daily discharge ascertained by applying to rating table mean daily gage 

height obtained from staff-gage readings prior to December 22, and thereafter 

by inspection from recorder graph corrected to agree with staff-gage readings. 

Owing to slight regulation, the mean of two staff-gage readings daily prior 

to December 22 may not indicate true mean stage. Records fan*.

COOPERATION. Gage-height record and some discharge measurements furnished 

by Washington Water Power Co.

ending Sept. 80, 1921.

SPOKANE VALLEY LAND & WATER CO.'S CANAL AT POST FALLS, IDAHO.

LOCATION. In NE. ^ sec. 4, T. 50 N., R. 5 W. Boise meridian, on right bank 

of Spokane River 1,200 feet below canal head gates and half a mile west 

of Post Falls, Kootenai County.

RECORDS AVAILABLE. May 20, 1911, to September 30,1917; September 6, 1919 r 

to September 30, 1921.

GAGE. Vertical staff on left side of flume; read by Emil Johnson. Prior to April 

21,1915, a vertical staff at end of flume, about 1,200 feet below present gage.

DISCHARGE MEASUREMENTS. Made from crossties on top of flume or from footbridge across flume one-fourth of a mile below gage.

CHANNEL AND CONTROL. Flume and canal section below gage; shifts continually, owing to effect of gravel bar at end of flume and plant growth, and 

possibly to regulation of head gates of diversion ditches below gage.
ITPPEE COLUMBIA RIVEE BASIN. 151

EXTREMES OF DISCHARGE. Maximum discharge,. 157 second-feet June 10-20. 

No water in canal October 1-6 and April 25 to May 8.

1911-1917 and 1919-1921: Maximum stage recorded, 3.2 feet June 18-22, 

1911 (discharge, 170 seeond-feet); no water in canal during periods in 1911, 

1912, 1916, 1917, 1919, 1920, and 1921.

ICE. Stage-discharge relation not affected by ice.

ACCURACY. Stage-discharge relation changed continually throughout the year. 

Rating curve defined by measurements made in April 22 and 23, 1920, well 

defined between 10 and 160 second-feet, is used as standard curve. Gage 

read to hundredths once daily, which is considered adequate for determination of mean daily gage height, since two submerged orifices and wasteway 

above canal head gate are instrumental in causing gage height of canal to 

remain constant even though the stage of the river is subject to considerable daily fluctuation. Daily discharge ascertained by shifting-control 

method* Records fair December to April, during which period no measurements were made; otherwise good.

COOPERATION. Gage-height record furnished by Spokane Valley Land & Water 

Co. and some discharge measurements furnished by Washington Water 

Power Co.

Canal diverts water from right bank of Spokane River in SE. ^i sec. 3, T. 50 

N., R. 5 W. Boise meridian. Water is used for irrigation.

4 p. m. May 26 (discharge, 20,8pO second-feet); no flow past gage at 4 

p. m. December 5 (water being impounded behind new dam).

1911-1921: Maximum and minimum stages recorded during 1921.

ICH. Stage-discharge relation seriously affected by ice at times.

DIVERSIONS. Some water is diverted for irrigation from tributaries above the 

station. The principal diversion is made from the river above the gage by 

West Okanogan Irrigation District, and has increased from about 75 secondfeet to about 140 second-feet since irrigation season of 1916. For discharge 

measurement of West Okanogan flume see under "Miscellaneous discharge 

measurements," page 217.

REGULATION. None.

ACCURACY. Stage-discharge relation changed with change of gage location on 

January 31; not affected by ice. Rating curves well defined. Gages read 

to tenths or half-tenths twice daily. Daily discharge ascertained by applying 

mean daily gage height to rating table. Records excellent.

COOPERATION. Gage-height record furnished by Okanogan Valley Power Co.

CHELAE? RIVER AT CHEIAW, WASH.

LOCATION. In sec. 13, T. 27 N., R. 22 E., at lower bridge at Chelan, Chelan 

County, 800 feet below flashboard dam at outlet of Lake Chelan and 4 

miles northwest of Chelan Falls.

DRAINAGE AREA. 950 square miles (measured on topographic and Forest 

Service maps).

RECORDS AVAILABLE. November 1, 1903, to September 30, 1921.

GAGE. Vertical staff on fourth bent of left approach to lower bridge; read 

by H. E. and C. M. Farley.

DISCHARGE MEASUREMENTS. Made from upper bridge 1,000 feet above gage, 

from boat, or by wading.

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

extremely high water. Channel curved above gage, but practically straight 

below. Banks high; not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 12.3 feet 

June 8 (discharge, 11,600 second-feet); minimum stage recorded, 4.9 feet 

September 6, 9-12, 14-18, 20, 24 (discharge, 586 second-feet).

1903-1921: Maximum stage recorded on June 8, 1921; practically no 

flow for at least part of day on January 30, 1917, when outlet to lake was 

blocked solid with floating ice so that no water could flow over dam.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Several irrigation ditches divert from tributaries a very small 

proportion of the run-off.

REGULATION. Flashboard dam 800 feet above gage controls lake level at low 

water in the interest of navigation. Monthly summaries of flow have been 

corrected for storage.

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

below 10,000 second-feet. Gage read to hundredths twice daily during 

October and November; once daily thereafter. Daily discharge ascertained by applying mean daily gage height to rating table. Records excellent.

RECORDS AVAILABLE. April 25, 1908, to September 30, 192 L

GAGE. Stevens continuous water-stage recorder on left bank about 600 feet 

below Sunnyside diversion dam; installed August 17, 1915; inspected by 

H. J. Uanson, E. E. Anderson, and H. C. Beardsley. For description of 

previous gages see Water-Supply Paper 442.

DISCHARGE MEASUREMENTS. Made from cable 80 feet above gage or by wading.

CHANNEL AND CONTROL. Bed composed of solid rock, large boulders, and gravel. 

One channel at all stages. Control formed by diagonal riffle about 250 

feet below gage; may shift slightly during extremely high floods.
184 SURFACE WATEE SLTPPLY, 1921, PAKT XII A.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage recorder, 9.19 feet at 9.15 p. m. May 17 (discharge, 17,600 second-feet); 

minimum stage, from recorder, 1.38 feet at 2.30 p. m. September 18 (discharge, 45 second-feet).

1908-1921: Maximum stage recorded, 15.0 feet at 1 p. m. December 30, 

1917 (discharge, 52,900 Second-feet); practically no flow October 26, 1911, 

August 25 and 28, 1915, and September 14, 1918.

ICE. Stage-discharge relation slightly affected by ice during severe winters..

DIVERSIONS. Water diverted above gage for irrigation of about 250,000 acre®.

REGULATION. Flow partly regulated by diversions, and by storage and release 

of water at Keechelus, Kachess, Cle Elum, and Bumping reservoirs.

\CCTJRACY. Stage-discharge relation permanent; not affected by ice. Rating 

curve well defined; revised slightly for use during year. Water-stage recorder inspected twice daily. 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 to rating table mean 

gage heights for shorter intervals. Records excellent October to July; others 

good.

storage dam, one-fourth of a mile above mouth, and 2 miles northwest of 

Easton, Kittitas County.

DRAINAGE ABE A. 64 square miles (measured on topographic maps).

RECORDS AVAILABLE. November 20, 1903, to September 30, 1921.'

GAGE. Stevens water-stage recorder at highway bridge; installed August 15, 

1916; inspected by Fred Diener. Original staff gage on left bank a quarter 

of a mile below Kachess storage dam was replaced by water-stage recorder at 

same site and datum July 22, 1913.

DISCHARGE MEASUREMENTS. Made from cabbie 20 feet below site of old gage 

or by wading.

CHANNEL AND CONTROL. Bed composed of light gravel and sand; shifting 

frequently. One channel at all stages. Control formed by broad riffle 125 

feet below gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.17 feet at 

5 p. m. August 24 (discharge, 1,840 second-feet); practically no flow on days 

for which discharge is not shown in table of daily discharge.

1904-1921: Maximum discharge, 2,240 second-feet (computed from gate 

opening) August 27, 1920; practically no flow when gates in dam are closed.

ICE. Stage-discharge relation affected by ice at times.

DIVERSIONS. None.

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

reservoir. Monthly discharge, without storage, determined from records 

of stage of reservoir.

ACCURACY. Stage-discharge relation changed frequently during year; not 

affected by ice. Standard rating curve fairly well defined; was used 

May 1-13. Parallel curves used October 1 to February 8, February 9 to 

April 30, May 14 to June 17, June 18 to July 31, August 1-10, 11-24, 

August 25 to September 9, and September 12-30. Gage read to hundreths 

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

.rating table except for September 10 and 11 for which it was ascertained 

by shifting-control method. Records fair.

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

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

County.

DRAINAGE AREA. 942 square miles (measured on topographic maps and Plate I, 

Water-Supply Paper 369).
UPPER COLUMBIA EIVEE BASEST. 193

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-, 

1921.

GAGE. Stevens continuous water-stage recorder on left bank; installed December 7, 1916; inspected by S. T. Asberry. 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 in two sections on left bank, 8' 

feet above cable; April 3, 1916, vertical staff installed to supplement in- 

, clined 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. One channel except at extremely high

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

recorder, 8.46 feet at 1 a. m. June 8 (discharge, 9,800 second-feet); minimum stage, from recorder, 2.21 feet at 8 p. m. September 16 (discharge, 

450 second-feet).

1905; 1909-1921: Maximum stage recorded, 8.9 feet at 8 a. m. November 

24, 1909 (discharge, 18,800 second-feet); minimum stage recorded, 1.62 

feet at 5 p. m. November 20, 1917, and 1.67 feet September 23, 1918 (discharge, 232 second-feet).

ICE. Stage-discharge relation seriously affected by ice during severe winters.

DIVERSIONS. Above all important diversions except Selah Valley and Tieton 

canals. Record of the amount of water diverted by these canals is obtained; 

for Selah Valley canal mean monthly discharge only is published as shown 

in the monthly discharge table below; for discharge of Tieton canal see 

page 200.

REGULATION. Plow 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 practically permanent; possibly slightly 

affected during low stages'by backwater from wing dam at intake of Wapatox 

canal. Rating curve well defined; revised above 4,000 second-feet for use 

during year. Water-stage recorder inspected daily. Daily discharge ascertained by applying daily mean gage height to rating table; daily mean gage 

height estimated for April 21 and 22, July 28 and 29, August 28, and September 7, owing to slight backwater effect from wing dam at intake of 

Wapatox canal, as indicated by graph from water-stage recorder. Records 

excellent October to July; others good.

COOPERATION. Station maintained by United States Bureau of Reclamation in 

cooperation with Pacific Power & Light Co. Bureau of Reclamation made 

discharge measurements and computed discharge.

NOTE. The monthly discharge, corrected for storage and diversions, as shown in the above tabte represent the natural yield as nearly as may be computed from stream-flow records. No account Is taken of 

depletion due to irrigation above gaging station, amounting to perhaps 6,000 acre-feet a year, and unmeasured waste above gaging station on Selah Valley canal, which reaches the river below the river 

gaging station. Accordingly the actual natural yield is larger than shown.

196 SURFACE WATEE SUPPLY, 1921, PART XII A.

BUMPING RIVER NEAR NILE, WASH.

LOCATION. A quarter of a mile below spillway of Bumping Lake dam, half a 

mile below outlet conduit through storage dam, llj^ miles above American 

River, and 19 miles west of Nile, Yakima County.

DRAINAGE AREA. 68 square miles (measured on topographic maps).

RECORDS AVAILABLE. June 13 to July 31, 1906; April 27, 1909, to September 

30, 1921.

GAGE. Stevens water-stage recorder; installed June 17, 1913; inspected by 

J. H. Nelson. Since June 17, 1913, vertical staff on left bank, one-fourth of 

a mile below spillway of storage dam; reconstructed at same site and datum 

April 27, 1915. For description of previous gages, see Water-Supply paper 

442.

DISCHARGE MEASUREMENTS. Made from cable about 40 feet below gage or 

by wading.

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

shifts at extremely high water. Riffle control 60 feet below gage. Stage 

of zero flow, gage height about 0.6 foot.

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

recorder, 5.22 feet at 8.30 p. m. June 7 (discharge, 1,890 second-feet); 

minimum stage, from recorder, 1.27 feet at 2.30 p. m. December 13 (discharge, 16 second-feet).

1906 and 1909-1921: Maximum stage recorded, 9.33 feet at 5 p. m. 

December 29, 1917 (discharge, 5,180 second-feet); practically no flow when 

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. r

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

curve fairly well defined; revised for use after October 5. Water-stage 

recorder inspected daily. Daily discharge ascertained by applying daily 

mean gage height to rating table or, for a few days when range in stage was 

considerable, by averaging results obtained by applying to rating table 

mean gage heights for shorter intervals. Records fair.

COOPERATION. Complete record furnished by United States Bureau of Reclamation.

Discharge measurements of Bumping River near Nile, Wash., during the year

ending Sept. SO, 1921.

canal, 15 miles above mouth, and 16 miles southwest of Naches, Yakima 

County.

DKAINAOE ABE A. 240 square miles (measured on topographic maps).

RECORDS AVAILABLE. April 17 to September 17, 1906 (fragmentary gageheight record); July 5t 1907, to September 30, 1921.

GAGE. Stevens continuous water-stage recorder on right bank about 1,000 feet 

below intake of Tieton canal; inspected by G. G. Willis. Priez water-stage 

recorder at same site used July 8, 1911, to 1918. For description of previous 

gages see Water-Supply Paper 442.

DISCHARGE MEASUREMENTS. Made from cable about 500 feet below gage or 

by wading.
198 SURFACE WATER SUPPLY, 1921, PART XII A.

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

at high water. One channel at all stages; gradient steep.

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

recorder, 5.68 feet at 9 a. m. June 7 (discharge, 2,580 second-feet); minimum 

stage, from recorder, 1.77 feet August 27 (discharge, 12.5 second-feet).

5 second-feet).

ICE. Stage-discharge relation affected by ice during severe winters.

DIVERSIONS. Tieton canal has diverted water above 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 permanent; not affected by ice. Rating 

curve well defined. Operation of water-stage recorder satisfactory. Daily 

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

Records good.

LOCATION. In see. 26, T. 10 N., R. 16 E., at Olney ranch, 1J^ miles below highway 

bridge, 3J^ miles southeast of Fort Simcoe, Yakima County, and 5 miles 

southwest of White Swan.

DRAINAGE AREA. 124 square miles (measured on PL I, Water-Supply Paper 

369).

RECORDS AVAILABLE. February 27, 1909, to September 30, 1921.

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

ranch house; installed August 19, 1915; inspected by J. P. McCafferty and 

A. B. Morrison. Previous gages as follows: February 27, 1909, to July 22, 

1913, on left bank a quarter of a mile above site of present gage; July 23, 

1913, to August 18, 1915, vertical staff attached to cottonwood -tree on right 

bank 150 feet above site of present gage.

DISCHARGE MEASUREMENTS. Made from cable or by wading.

CHANNEL AND CONTROL. Bed composed of gravel and small boulders. Concrete control constructed in September, 1916, is gradually being washed 

away. Banks covered with brush; subject to overflow at extremely high 

water.

EXTREMES OF DISCHARGE. Maximum stage during ye&r, from water-stage 

recorder, 4.85 feet at 4 p. m. December^ 30 (discharge, 1,070 second-feet); 

minimum stage, from recorder, 1.11 feet at 10.30 p. m. July 22 (discharge, 

4.2 second-feet).

1909-1921: Maximum discharge recorded, 1,650 second-feet at noon 

May 4,1916; minimum stage recorded, 1.14 feet August 15 and September 18, 

1920 (discharge, 3.0 second;-feet).

Ic®. Stage-discharge relation affected by ice at times.

DIVERSIONS. Toppenish Feeder canal operated since April 1, 1921, diverted a 

maximum of about 25 second-feet during the season. In addition to new 

acreage, this canal fulfills irrigation requirements formerly taken care of by 

Nicol and Abe Lincoln ditches, which have been abandoned. Diversion 

through canal added to mean monthly flow to determine natural monthly 

flow past gage. Diversion of spring run-off into reservoir on Simcoe Creek 

for use in irrigating Indian lands is proposed.

REGULATION. None.

ACCURACY. Stage-discharge relation changed gradually October 1-22, abruptly 

on February 10, and at crest of spring flood April 22; not affected by ice. 

Standard rating curve used prior to April 22, fairly well defined; curve used 

thereafter, well defined. Parallel curves used October 23 to February 10 and 

February 10 to March 18. Operation of water-stage recorder fairly satisfactory except as noted in footnote to table of daily discharge. Daily discharge ascertained by applying to rating table mean daily gage height 

determined by inspection from recorder graph. Shifting-control method 

used October 1-22. Records fair October to April: good thereafter.

NOTB. Water-stage recorder not operating Oct. 1-27, and Nov. 19-26; discharge ascertained by interpolating between discharge from occasional staff gage readings or by comparison with flow of Satus Greek. 

Braced figures show mean discharge for periods indicated. Observer estimated that about 25 second-feet 

wasted down Abe Lincoln ditch on Nov. 18,19, 20, and 21, about SO second-feet for a few hours on Dec. 30, 

and about 15 second-feet on Feb. 11 and in addition 20 second-feet passed down a draw above gage, and about 

30 second-feet passed around gage on Mar. 19; not included in above table.

SIMCOE CHEEK BELOW SPRING CREEK, NEAR FORT SIMCOE, WASH.

LOCATION In sec. 34, T. 11 N., R. 16 E., at site of proposed reservoir, 4 miles 

northeast of Fort Simcoe, Yakima County.

DRAINAGE AREA. 77 square miles (measured on PL I, Water-Supply Paper 

369).

RECORDS AVAILABLE. November 20, 1915, to September 30, 1921. For a 

station just above Spring Creek, February 28, 1909, to November 20, 1915.

GAGE. Stevens continuous water-stage recorder on left bank just below Spring 

Creek; installed November 20, 1915; inspected by Ivan Hartzell, J. P. 

McCafferty, and A.'B. Morrison. Previous gages as follows: Prior to 

March 24, 1910, a chain gage 100 yards above Spring Creek; March 24, 

1910, to November 20, 1915, staff gage at same site and datum.

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

Several overflow channels were created during high water of December 30, 

1920, and since that date discharge measurement at medium and high 

stages include measured flow in these channels.

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

16 feet below gage. Right bank high; left bank overflows at medium stage.

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

recorder, 4.15 feet at 1.30 p. m. February 13 (discharge, 296 second-feet); 

minimum discharge, probably less than 0.1 second-foot during periods 

October 1-8 and 11-20.

1916-1921: Maximum stage recorded, 6.14 feet at 5 p. m. 

February 10, 1916 (discharge, 731 second-feet); minimum discharge probably occurred in October, 1920.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Considerable water is diverted above station for irrigation. 

Since about April, 1920, Simcoe Creek flume has diverted from 0.25 secondfoot to 5 second-feet from a point just above Spring Creek. Monthly discharge has been corrected for estimated diversion through flume.

REGijiiATioN. None.

ACCURACY. Stage-discharge relation changed during flood of December 30, 

1920, when headworks of Simcoe Creek flume were washed out and several 

new, channels were formed which carried a large percentage of the water 

around gage during period December 30 to June 10. Rating curve used 

prior to change fairly well defined; curve used after change fairly well 

defined between 10 and 150 second-feet. Operation of water-stage recorder 

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

Daily discharge ascertained by applying to rating table mean daily gage 

height determined from recorder graph by inspection. Records fair June 

to August; otherwise poor.

June 10-15 (discharge, 624 second-feet); minimum stage recorded, 3.02 

feet April 9 (discharge, 196 second-feet).

1913-1921: Maximum stage recorded, 8.2 feet on January 2, 1918, 

from high-water mark (discharge, estimated 1,500 second-feet); minimum 

stage recorded, 1.8 feet July 3, August 12, 15-31, September 1-14, 19, 

1915 (discharge, 145 second-feet).

ICE. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed gradually October 1 to February 

13. Standard rating curve fairly well defined. Gage read to quartertenths once daily. Daily discharge ascertained by applying daily gage 

height to rating table. Shifting-control method used October 1 to February 

13. Records good.

COOPERATION. Some discharge measurements made by United States Office 

of Indian Affairs.
