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, 1922.

The data presented in these reports were collected by the United 

States Geological Survey under the following authority contained in 

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

Provided, That this officer [the Director] shall have the direction of the Geological Survey and the classification of public lands and examination of the 

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

The work was begun in 1888 in connection with special studies 

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

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

carried the following item and appropriations:

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

and for the investigation of underground currents and artesian wells, and for 

the preparation of reports upon the best methods of utilizing the water resources.

Annual appropriations for the fiscal years ending June SO, 1895-1928.

2 SURFACE WATER SUPPLY, 1922, PART XII A.

Measurements of stream flow have been made at about 5,480 

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

Hawaiian Islands. In July, 1922, 1,540 gaging stations were being 

maintained by the Survey and the cooperating organizations. Many 

miscellaneous discharge measurements were made at other points. 

In Connection with this work data were also collected in regard 

to precipitation, evaporation, storage reservoirs, river profiles, and 

water power in many sections of the country and will be made available in the water-supply papers from time to time.

DEFINITION OF TERMS.

The volume of water flowing in a stream the "run-off" or "discharge" is expressed in various terms, each of which has become 

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

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

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

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

The principal terms used in this series of reports are second-feet, 

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

may be defined as follows:

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

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

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

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

unit from which others are computed.

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

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

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

regards time and area.

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

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

distributed on the surface. It is used for comparing run-off with 

rainfall, which is usually expressed in inches.

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

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

The following terms not in common use are here defined:

"Stage-discharge relation," an abbreviation for the term "relation 

of gage height to discharge."

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

stream below the gage which determine the stage-discharge relation 

at the gage. It should be noted that the control may not be the 

same section or sections at all stages.

EXPLANATION OF DATA. 3

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

on the gage the gage height at which water ceases to flow over

the control.

EXPLANATION OF DATA.

The data presented in this report cover the year beginning October 

1, 1921, and ending September 30,1922. At the beginning 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 run-off 

for a 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 gage or from a water-stage recorder that 

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

of river discharge.

From the discharge measurements, rating tables are prepared that 

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

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

monthly, and yearly means of discharge are determined.

The data presented for each gaging station in the area covered by 

this report comprise a description of the station, a table giving records of discharge measurements, a table showing the daily discharge 

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

run-off.

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

tables giving daily gage height and records of discharge measurements 

are published.

The description of the station gives, in addition to statements 

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

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

for log driving, shifting of control, 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.

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

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

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

fluctuation the discharge obtained from the rating table and the 

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

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

the mean daily discharge is obtained by averaging discharge at 

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

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

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

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

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

indicate correctly the stage when the water surface was at crest 

height and the corresponding discharge was consequently larger than 

given in the maximum 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" is 

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

this average flow computations recorded in the remaining columns, 

which are defined on page 2 are. based.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS.

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

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

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

records.

A paragraph in the description of the station gives information 

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

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

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

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

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

the individual measurements with reference to the mean rating curve.

The monthly means for any station may represent with high 

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

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

information' concerning water diverted for irrigation or other use, 

or by inability to interpret the effect of artificial regulation of the 

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

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

appear probable. The computations are also omitted for stations

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

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

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

be used with caution because of possible inherent sources of error 

not known to the Survey.

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

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

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

to throw new light on data previously published.

PUBLICATIONS.

Investigation of water resources by the United States Geological 

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

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

it has comprised also 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 

coincide with natural drainage features, as indicated below:

Part I. North Atlantic slope basins.

II. South Atlantic slope and eastern Gulf of Mexico basins.

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 

1922. The data for any particular station will, as a rule, be found in

GAGING STATION RECORDS.

QUINAULT RIVER BASIN.

QUINAUIT RIVER AT QUINATJLT LAKE, WASH.

LOCATION. In sec. 25, T. 23 N., R. 10 W., at outlet of Quinault Lake, 4 miles 

southwest of Quinault and 33 miles north of Hoquiam, Grays Harbor County.

DRAINAGE AREA. 264 square miles (measured on PL I, U. S. Geol. Survey Prof. 

Paper 7).

RECORDS AVAILABLE. October 29, 1911, to December 21, 1922, when station 

was discontinued.

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.

DISCHARGE MEASUREMENTS. Made from cable 700 feet above gage.

CHANNEL AND CONTROL. Bed composed of boulders. Well-defined control 600 

feet below gage. Left bank high and wooded; not subject to overflow; right 

bank high, wooded, and subject to overflow above gage height about 20 feet.

EXTREMES OP DISCHARGE. Maximum stage recorded during period October 1, 

1921, to December 21, 1922, from water-stage recorder, 16.3 feet at 5 p. m. 

December 12, 1921 (discharge, 37,000 second-feet); minimum stage from 

recorder, 1.30 feet from 1 a. m. to 1 p. m. September 21 (discharge, 560 

second-feet).

1911-1922: Maximum stage recorded that of December 12, 1921; minimum stage recorded, 0.1 foot at 7 a. m. October 1, 1915 (discharge, 395 

second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. Flow regulated by natural storage in the lake.

ACCURACY. Stage-discharge relation permanent; affected by drift November 

24-26, 1921, and December 19-21, 1922. Rating curve well defined. 

Operation of water-stage recorder satisfactory. Discharge ascertained by 

. applying to rating table daily mean gage height obtained by inspecting gageheight graph or, for days of considerable variation in stage, by averaging 

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

27, 1901 (discharge, 23,800 second-feet); minimum discharge, 170 secondfeet October 18, 1897.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

RKGULATION. None.

ACCURACY. Stage-discharge relation changed October 28 and gradually over 

the periods December 10-12, December 30 to April 27, and May 3 to July 

13. Rating curve developed in 1922, well defined below 5,000 second-feet 

used as standard form of curve, to which changes in control, indicated 

by frequent discharge measurements, have been assumed to yield curves 

parallel. Shifting-control method used over periods of gradual change.
16 SURFACE WATER SUPPLY, 1922, PART XII A.

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 gage height obtained by inspecting gage-height graph, or for 

days of considerable fluctuation, by averaging results obtained by applying 

gage heights for shorter intervals. Records good.

COOPERATION. Gage-height record and some discharge measurements furnished 

by Northwestern Power & Manufacturing Co.

Discharge measurements of Elwha River at McDonald Bridge, near Port Angelesf 

Wash., during the year ending Sept. 30, 1922.

PUQET SOUND BASINS.

SKOKOMISH RIVER BASIN. 

NORTH FORE OF SKOKOMISH RIVER NEAR HOODSPORT, WASH.

LOCATION. In SW. ^ 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, 1922.

GAGE. Stevens water-stage recorder on left bank just below trail bridge; inspected by Phillip Abbey and O. A. Abelson. 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 OP DISCHARGE. Maximum stage recorded during year, from slightly 

damaged record of water stage, 16.7 feet at 5 p. m. December 12 (discharge, 

12,100 second-feet); minimum stage, from recorder, 0.87 foot at 1 p. m. 

September 21 (discharge, 125 second-feet).

1913-1922: Maximum stage estimated at 23.5 feet January 6, 1914, 

during part of day when recorder was not operating (discharge estimated 

at 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. Flow regulated by natural storage at Lake Cushman. .
18 SURFACE WATEE SUPPLY, 1922, PART XII A.

ACCURACY. Stage-discharge relation changed May 16, August 9, and September 

27. Rating curve used prior to May 16 well defined below 5,000 second-feet; 

curves used May 16 to September 27 fairly well defined and last curve poorly 

defined. 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 or for days when variation in stage was considerable by averaging 

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

excellent except for. extreme high water until May 15; good thereafter.

COOPERATION. Maintained in cooperation with the city of Tacoma.

NISQUALLY EIVER BASIN. 

NISQUAIIY RIVER NEAR IA GRANDE, WASH.

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

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

Pierce County.

DRAINAGE AREA. 287 square miles (measured on topographic map of Mount 

Rainier National Park, map of Rainier National Forest, edition of 1918, 

and PI. IV, U. S. Geol. Survey Water-Supply Paper 313).

RECORDS AVAILABLE. October 1, 1919, to September 30, 1922; September 5, 

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 head-gate 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 MEASUREMENTS. 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, 15.6 feet from 3.30 to 6 a. m. on December 12 (discharge, 19,200 

second-feet). Possibly no flow at gage for parts of several days in January, 

February, March, and September when entire flow was diverted into power 

conduit.

1920-1922: Maximum stage recorded, that of December 12, 1921. 

Possibly no flow at gage for parts of days when entire flow is diverted into 

power conduit.

ICE. Stage-discharge relation not affected by ice.

DIVERSION. 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.
20 SURFACE WATER SUPPLY, 1922, PAET XII A.

ACCURACY. Stage-discharge relation permanent; affected by silt washed from 

settling basin and behind dam as noted in footnote to table of daily discharge. Rating curve for normal control conditions well defined. Operation 

of water-stage recorder satisfactory. Daily discharge ascertained by use of 

discharge integrator except for extreme high water when discharge was determined by applying mean daily gage height to rating table or, for days of 

considerable variation in gage height, by averaging results obtained by 

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

extreme low water when amount of backwater effect is doubtful.

COOPERATION. Maintained in cooperation with city of Tacoma.

Discharge measurements of Nisqually River near La Grande, Wash., during the 

year ending Sept. 80, 1922.

August 6 to September 20, 1920, gage heights obtained from reference 

point in rock at site of present gage and same datum; September 30 to 

December 30, 1920, staff gage at same site but at datum 17.0 feet lower than 

that of present gage; January 1-27, 1921, staff gage at practically same site 

and at datum 0.22 foot lower than that of present gage; January 28 to 

April 19, 1921, staff gage at present site but at datum 0.12 foot lower than 

present gage. All gage readings referred to present datum.

DISCHARGE MEASUREMENTS. Made by wading or from cable.

CHANNEL AND CONTROL. One channel at all stages. Banks high; not subject 

to overflow. Control is riffle in heavy boulders 100 feet below gage. At 

extremely high stage, gage is on riffle.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 6.4 feet at midnight December 11 (discharge, 2,020 secondfeet); minimum stage recorded, 0.97 foot on August 9 and September 21 

(discharge, 8.5 second-feet).

1920-1922: Maximum stage recorded that of December 11, 1921; minimum discharge, 8.2 second-feet on September 16 and 17, 1921.

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

DIVERSION. None.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent; affected by ice January 18-21. 

Rating curve well defined below 1,500 second-feet. Operation of waterstage recorder satisfactory except as noted in footnote to table of daily 

discharge. Discharge ascertained by applying to rating table mean daily 

gage height obtained graphically from automatic record. Records excellent 

except for periods of missing gage-height record.

PUYALLUP RIVER BASIN. 

PUYALLUP RIVER NEAR ELECTRON, WASH.

LOCATION. In NE. M NW. M sec. 3, T. 16 N., R. 6 E., 1,000 feet above intake 

of Puget Sound Power & Light Co.'s flume, a quarter of a mile below 

Mowich River and 10 miles southeast of Electron, Pierce County.
PUYALLUP BIVER BASIN. 27

DRAINAGE AKBA. 91 square miles (measured on PI. IV, Water-Supply Paper 

313).

RECORDS AVAILABLE. January 1, 1909, to September 30, 1922.

<jAQB. :Friez water-stage recorder on left bank at gaging bridge 1,000 feet 

above intake; inspected by William Chambers. Datum lowered 1.00 foot on 

March 9, 1918.

DISCHARGE MEASUREMENTS. Made from gaging bridge at gage.

CHANNEL AND CONTROL. Channel straight for 150 feet above and below gage. 

Banks high and wooded. One channel at all stages. Bed composed of 

boulders and glacial debris; shifting.

EXTREMES OF DISCHARGE. Maximum stage recorded during year from waterstage recorder, 6.65 feet at 3 p. m. December 12 (discharge, 4,560 secondfeet); minimum stage, from recorder, 0.38 foot at 7 p. m. on March 17 

(discharge, 118 second-feet).

1909-1922: Maximum discharge estimated from partial gage height 

record December 18, 1917 (discharge, 4,800 second-feet); minimum discharge estimated at 112 second-feet on December 24, 1914, when stagedischarge relation was affected by ice.

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

DIVERSIONS. None above station.

REGULATION. None.

ACCURACY. Stage-discharge relation changed frequently during year; affected 

by ice January 19, 20, 30, 31, and February 1-4. Rating curve developed 

in 1922 and well defined below 2,000 second-feet has been used as standard 

form of curve for the year and changes in control indicated by frequent 

discharge measurements have been assumed to yield curves parallel to this. 

See footnote to table of daily discharge. 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 or, for days of considerable variation 

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

shorter intervals. Records good.

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

and made discharge measurements.

"LOCATION. On line between sec. 25, T. 20 N., R. 4 E., and sec. 3Q> T. 20 N., 

R. 5 E., at highway bridge 1 mile north of Alderton, Pierce County, and 1^ 

miles above Stuck River.

DRAINAGE AREA. 410 square miles (measured on PL IV, Water-Supply Paper 

313).

RECORDS AVAILABLE. November 20, 1914, to September 30, 1922.

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

Mrs. H. D. Foster. Vertical staff in two sections on downstream side of 

bridge pier on right bank used to January 15, 1920. Several temporary 

staff gages just below bridge used January 16 to December 14, 1920. Datum 

of gage lowered 1 foot August 5, 1918.

DISCHARGE MEASUREMENTS. Made from bridge at gage.

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, 11.5 feet at 

11 a. m. December 12 (discharge, 21,200 second-feet); minimum stage 

recorded, 0.73 foot September 30 (discharge, 495 second-feet).

1915-1922: Maximum stage recorded that of December 12, 1921; minimum 

discharge, 342 second-feet, October 10, 1919.

ICE. Stage-discharge relation slightly affected by ice for a few days during 

severe winters.

DIVERSION. None.

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

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

is small.

ACCURACY. Stage-discharge relation changed December 1 and gradually April 

1 to May 18, and June 2 to July 6. Rating curves fairly well defined. Gage 

read to hundredths once daily. Slight diurnal fluctuation. Daily discharge ascertained by applying daily gage height to rating table. Shiftingcontrol method used April 1 to May 18 and June 2 to July 6. 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. J4 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.
PUYALLUP BITBE PASIN. 31

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

Paper 313).

RECORDS AVAILABLE. May 1, 1914, to September 30, 1922.

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 OF DISCHARGE. Maximum stage recorded during year from waterstage recorder, 17.05 feet at 2 a. m. December 13 (discharge, 35,600 secondfeet); minimum stage recorded, 1.21 feet at 8 a. m. September 24 (discharge) 

1,160 second-feet); may have been lower on same and other days while 

intake was above water.

1914-1922: Maximum stage recorded, 34.15 feet at 4.45 p. m. December 

18, 1917 (discharge, 40,500 second-feet); minimum discharge, 726 secondfeet at 8 p. m. November 18j 1917.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Two hydroelectric plants, owned by the 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 into 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 frequently. Well defined rating 

curve developed during 1921 used as standard form of curve for this station 

and changes in control indicated by frequent discharge measurements 

have been assumed to yield curves parallel to this. Water below intake 

for several long periods. In general and except as noted in footnote to 

daily-discharge table, discharge below about 2,500 second-feet has been 

determined by increasing by 10 per cent results obtained by applying one 

early morning staff-gage reading to rating table after correcting for shift 

in accordance with results of discharge measurements; 10 per cent increase 

based upon diurnal fluctuation due to regulation of White River for power, 

as indicated on recorder graph for stages yielding slightly more than 2,500 

second-feet. Operation of water-stage recorder satisfactory when stage 

was above intake except as noted in footnote to table of daily discharge. 

Daily discharge, November 22 to December 22, and May 3 to July 17, 

ascertained by applying to rating table mean daily gage height obtained 

by inspecting recorder graph and corrected as to time and amount of shift 

in accordance with results of discharge measurements. Records good 

December and May to July; otherwise fair.

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

WHITE EIVEE AT BUCKLEY, WASH.

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

bridge 1 mile northeast of Buckley, Pierce County.

DRAINAGE 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, 1922.

GAQE. 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, and after 

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

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

in South Channel, caused by flood on January 23, 1919; installed at railway 

bridge April 2, 1919, moved 700 feet upstream June 11, 1919. Gage read 

by O. E. Osgood.

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 OF DISCHARGE. Maximum combined daily discharge of river and 

flume, 11,500 second-feet December 12; minimum combined daily discharge, 410 second-feet January 18.

1899-1901; 1911; 1913-1922: 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 fVom determinations of combined flow of river and flume.
SURFACE WATER SUPPLY, 1922, PART XII A.

ACCTTBACY. Stage-discharge relation for main channel changed several times 

during year; radically with destruction by flood of city of Tacoma's 

pipe line protection November 30. Rating curve developed in 1921 and 

poorly defined has been used as standard form of curve October 1 to November 30, and curve developed in 1921-22, fairly well defined below 5,000 secondfeet, has been used as standard form for the period December 1 to September 

13. Changes in control indicated by frequent discharge measurements have 

been assumed to yield curves parallel to one or the other of these curves, 

depending upon whether shift occurred prior or subsequent to radical change 

on November 30. See footnote to table of daily discharge. A fairly welldefined curve has been used direct September 14-30. Stage-discharge relation for secondary channel changed October 1 to November 4 and on 

December 12. Rating curves poorly defined. Flow from river through this 

channel so slight as to be negligible except for the periods November 30 to 

December 2 and December 11-13.

Daily discharge is combined flow of two channels. That for main channel 

ascertained by applying to rating table mean daily gage height determined 

graphically from automatic gage-height record or for days of considerable 

variation in stage by applying mean gage heights for shorter intervals. 

Daily discharge for secondary channel ascertained by applying daily gage 

reading to rating table or for days for which gage-height record was doubtful 

by comparison with flow of main channel. Records of combined flow fair.

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

and made discharge measurements.

WHITE RIVER FLUME AT BUCKLEY, 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, 1922.

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 OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 6.05 feet from 7 to 9.30 a. m. May 1 (discharge, 1,780 secondfeet) . No flow in flume when headgates are closed for cleaning flume or on 

account of high water.

1913-1922: Maximum stage recorded, 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 head gates are closed.

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

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

ACCURACT. Stage-discharge relation changed continuously throughout the year. 

Slightly affected by ice January 29 to February 1. Rating curve developed 

in 1918 used as standard form of curve for this station and changes in control indicated by frequent discharge measurements have been assumed to 

yield curves parallel to this. Operation of water-stage recorder satisfactory. 

Daily discharge ascertained by shifting-control method. Records good.

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

and discharge measurements.

Flume diverts water from left bank of White River in the SE. % sec. 35, T. 

20 N., R. 6 E. Water is used for power development at Dieringer and then is 

discharged into Stuck River.

DTJWAMISH BIVER BASIN. 

CEDAR RIVER AT CEDAR FALLS, WASH.

LOCATION. In sec. 4, T. 22 N., R. 8 E., below Seattle municipal power plant at

Cedar Falls, King County, and 3^ miles above Taylor Creek. 

DEAINAGE AEEA. 83 square miles (measured on topographic maps). 

RECORDS AVAILABLE. April 9, 1914, to September 30, 1922.
38 SURFACE WATER SUPPLY, 1922, PART XII A.

GAGE. Stevens continuous water-stage recorder on right bank, 0.7 mile below 

power plant; installed April 8, 1914; inspected by E. C. and F. H. Hoffstrom.

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

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

extremely high water. Banks high. One channel at all stages. Stage of 

zero flow, according to measurements made September 25-26, 1922, at gage 

height 3.7 feet.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 10.52 feet at 10 p. m. December 12 (discharge, 4,500 secondfeet) ; minimum stage from recorder, 4.02 feet from 2 to 8 p. m. September 

20 (discharge, 1.4 second-feet). .

1914-1922: Maximum stage recorded, 11.4 feet at 9 a. m. December 19, 

1917 (discharge, 6,290 second-feat); minimum stage recorded, 3.32 feet at 4 

p. m. November 25, 1917 (discharge, zero).

ICE. Stage-discharge relation not affected by ice.

DIVERSION. Seattle municipal power plant diverts water directly from Cedar 

Lake through a pressure pipe and returns it to the river at the plant above 

the gage. Practically the entire flow at low water is carried through the 

plant.

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 slightly October 7, 14, and December 11-16. Rating curves used prior to December 10, fairly well denned; 

curve used since December 17, well denned. Operation of water-stage 

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

Daily discharge ascertained by use of discharge integrator. Shifting-control method used December 11-16. Records excellent.

COOPERATION. Gage-height record and some discharge measurements furnished 

by city of Seattle.

Discharge measurements of Cedar River at Cedar Falls, Wash., during the year

ending Sept. SO, 1922.

40 , SURFACE WATER SUPPLY, 1922, PART XII A.

CEDAR RIVER NEAR LANDSBIRG, WASH.

LOCATION. In sec. 17, T. 22 N., R. 7 E., 1% miles above intake of Seattle watersupply system at Landsberg, King County, 3 miles northeast of Ravensdale 

and 5 miles below Taylor Creek.

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

RECORDS AVAILABLE. April 30, 1914, to September 30, 1922; 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, 1917, about gage 

height 2.5 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 12.03 feet at 9 p. m. December 12 (discharge, 5,990 secondfeet); water below intake on September 20; stage and discharge not 

determined.

1914-1922: 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.

DIVERSION. None above the 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 December 12. Rating curve 

used prior to change well defined up to 1^500 second-feet; that used after 

change fairly well defined. Operation of water-stage recorder excellent 

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

ascertained by use of discharge integrator. Records excellent except for 

extremely high water, prior to December 12; good thereafter.

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

REGULATION. None.

ACCURACY. Stage-discharge relation changed with change in gages December 

12-20 and at high water May 17; not affected by ice. Rating curve used 

prior to first change well defined below 5,000 second-feet; latest curves poorly 

defined. Gage read to hundredths once daily; oftener during floods. Some 

diurnal fluctuation during summer. Daily discharge ascertained by applying 

daily gage height to rating table. Records good below 5,000 second-feet 

prior to December 11; fair thereafter.

48 SURFACE WATER SUPPLY, 1922, PART XII A.

MIDDLE FORE OF SNOQUALMIE RIVER NEAR NORTH 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,

DRAINAGE 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, 1922.

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 recorded during year, from waterstage recorder, 11.9 feet at 2 p. m. December 12 (discharge, 17,300 secondfeet); minimum stage, from recorder, 1.66 feet on August 29 or 30, when 

clock was stopped and only range of stage recorded (discharge, 215 secondfeet).

1907-1922: 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 of 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.

REGULATION. None.

ACCURACY. Stage-discharge relation changed December 12 and April 8. Rating 

curves used prior to first change well defined below 5,000 second-feet. Curveused December 12 to April 7 poorly defined. Latest curve well defined 

below 7,000 second-feet. Operation of water-stage recorder satisfactory 

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

ascertained by applying to rating table mean daily gage height determined 

graphically from automatically made record or, for days of considerablevariation 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 good October, November, and April to 

September; otherwise fair.

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

and made some discharge measurements.

DRAINAGE AREA. Approximately 102 square miles (measured on topographic 

and county maps).

RECORDS AVAILABLE. July 4, 1907, to September 30, 1922.

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

house; installed September 26, 1916; inspected by employees of Puget 

Sound Power & Light Co. For description of previous gages see WaterSupply 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. Left bank not subject to overflow; right bank 

fairly high, not subject to overflow except at extremely high stages. Stage 

of zero flow, according to measurements 'made August 2/5,, 1922, gage height 

0.0 ±0.3 foot.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 9.9 feet at 11 a. m. December 12 (discharge, 8,630 secondfeet); may have been as high or higher on December 11. Minimum stage 

recorded, 1.80 feet at 4 p. m. August 30 (discharge, 87 second-feet).

1907-1922: Maximum stage, determined by leveling to high-water mark, 

14.5 feet November 18, 1911 (discharge, 11,100 second-feet); water above 

gage November 18, 19, 23, 24, 29, and 30, 1909, and stage may have exceeded 

that reached in 1911. Minimum stage recorded, 1.0 foot September 26-28, 

1910 (discharge, 56 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent. Rating curve revised slightly 

January 1; well defined below 3,000 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 determined graphically from automatically made record, or, for days 

of considerable variation in stage, by averaging results obtained by applying mean gage heights for shorter intervals. Records excellent except for 

extremely high water and for periods when intake was clogged.

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

and made some discharge measurements.

SURFACE WATEE SUPPLY PART XII A.

SOUTH FORK OF SNOQUALMIE RIVEE 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 3J^ miles, by river, above mouth. 

DRAINAGE AREA. 84 square miles (measured on topographic maps). 

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

September 30, 1922. 

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

October 2, 1916; inspected by employees of Puget Sound Power & Light Co.

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

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

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

EXTREMES OP DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 10.8 feet at 2 p. m. December 12 (discharge, 6,780 secondfeet); minimum stage from recorder, 1.19 feet September 25 and 26 (discharge, 109 second-feet).

1907-1922: 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.

DIVERSION. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed at high water December 12 and 

May 5, and owing to removal by blasting of drift from control February 28 

to March 28. Rating curve used prior to December 12 well defined below 

3,000 second-feet; curves used December 12 to May 4 poorly defined; curve 

used May 5 to September 30 fairly well defined between 100 and 1,800 

second-feet. Operation of water-stage recorder satisfactory. Daily discharge ascertained by applying to rating table the mean daily gage height determined graphically from automatically made record 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 

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 results. Records good October, November, and May to 

September; otherwise fair.

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

and made some discharge measurements.

64 SURFACE WATER SUPPLY, 1922, PART XII A.

STILAGUAMISH RIVER BASIN. 

DEER CREEK AT OSO, WASH.

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

North Fork of Stilaguamish River, Snohomish County.

DRAINAGE AREA. 84 square miles (measured on topographic|maps).

RECORDS AVAILABLE. August 11, 1917, to September 30, 1922.

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.

DISCHARGE MEASUREMENTS. 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 from high-water marks 

in well, 11.7 feet on December 12 (discharge, 10,400 second-feet); minimum 

stage, from recorder, 0.70 foot August 8-10 (discharge, 45 second-feet).

1918-1922: Maximum stage recorded that of December 12, 1921; minimum discharge, 27 second-feet September 29 and 30, 1919.

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

DIVERSION. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed December 13; not affected by ice. 

Rating curve used prior to change well defined below 3,000 second-feet; 

that used subsequent to December 13 well defined below 2,000 second-feet. 

Operation of water-stage recorder satisfactory except as noted in footnoteto table of daily discharge. Clogged intake pipe interfered with correct 

registering of low-water gage heights for long periods as noted in footnote 

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

rating table mean daily gage height determined graphically from automatically made record or, for days of considerable variation in stage, by 

averaging results obtained by applying mean gage heights for shorter 

intervals. Records excellent October, November, and May to August; 

good for September; otherwise fair.

COOPERATION. Station maintained in cooperation with Western Power Co.

SKA6IT 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, 

three-fourths of a mile above Stetattle Creek, 1J^ miles below Thunder 

Creek, and 19 miles northeast of Marblemount, Skagit County.

DRAINAGE ABBA. 1,100 square miles. Area in United States measured on 

Washington National Forest map, 1922 edition. Area in British Columbia 

390 square miles.2

HECORDS AVAILABLE. December 6, 1913, to September 30, 1922, when records 

were discontinued.

 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. Prior to April 13, 1914, inclined staff at same site but at datum 

2.00 feet higher.

DISCHARGE MEASUREMENTS. Made from cable 50 feet below gage.

 CHANNEL AND CONTROL. 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, 14.1 feet at 7 p. m. December 12 (discharge, 58,000 second-feet); 

minimum stage recorded, 1.72 feet at noon February 24 (discharge, 704 

second-feet).

1913-1922': Maximum stage recorded that of December 12, 1921; minimum stage, from recorder, 1.64 feet from 4 p. m. November 11 to 9 p. m. 

November 12, 1919 (discharge, 665 second-feet).

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

basin indicates that a great flood occurred sometime prior to 1879. Highwater 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 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 slightly affected by ice during severe winters; 

discharge determined from observer's notes and weather records.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed at high water on December 12; 

affected by ice December 19-26 and January 26 to February 4. Rating 

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

that intake pipe to stilling well was clogged for long periods resulting in a 

lag between river and stilling well heights. 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 good.

COOPEEATION. Maintained in cooperation with city of Seattle.

RECORDS AVAILABLE. May 1, 1908, to December 31, 1919, and February 1« 

1921, to September ,30, 1922. Monthly mean discharge for period of missing 

records computed as described in footnote to tables of monthly discharge.

GAGE. Vertical staff on upstream draw guard of railway bridge, installed about 

May 1, 1908, read by E. J. Woods May 1, 1908, to September 26, 1916, 

and by W. H., Gale beginning February 1, 1921. From September 27, 1916, 

to September 2, 1919, chain gage on railway bridge, read by E. J. Woods, 

Temporary vertical staff, installed September 25, 1915, and used until 

September 26, 1916, whenever stage was below 37 feet. Temporary vertical staff Iocs i ed on downstream side of groups of piles, 50 feet above third 

concrete pier of railway bridge from left bank; at same datum as original 

vertical staff. Zero of gages set at elevation of extreme low water in Puget 

Sound. A staff gage on upstream shoreward side of highway bridge, 1,500 

feet above present gage and at different datum, was read September 28 to 

December 31, 1919.

DISCHARGE MEASUREMENTS. Made from highway bridge 1,500 feet above gage 

or from Northern Pacific Railway bridge at gage. Beatty's slough measured 

from highway bridge.

CHANNEL AND CONTROL. Gravel; shifts at high stages; banks not subject to 

overflow except during floods.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 30, 1922, 54.3 feet at 8 a. m. December 13 (discharge, 210,000 secondfeet); minimum stage recorded, 33.5 feet February 2-4 and March 30 (discharge, 4,680 second-feet).

1908-1922: Maximum stage recorded, 56.5 feet at 9 a. m. November 30, 

1909 (discharge, 220,000 second-feet); 4 maximum stage and discharge of flood 

of December, 1917, published in Water-Stfpply Paper 482, page 45, and 

Water-Supply Paper 512, page 85, found to be in error. More complete 

information and additional high-water marks indicate maximum stage was 

54.1 feet at 4 a. m. December 30, 1917 (discharge, 195,000 second-feet). 

Earlier floods are known to have occurred about as follows: 

Between 1805 and 1825, as estimated from Indian tradition, maximum 

stage 63.5 feet determined by comparison with stage at The Dalles where 

stage was known by a deposit of flood sand in a protected eddy (discharge, 

about 400,000 second-feet by comparison with flow at The Dalles).

About 1856, as indicated by the age of trees growing on a bar at an elevation lower than stage of this flood and at a point where high velocity and 

drift at that time cleared the bar of any trees that may have been growing, 

and probably December, 1856, as indicated by precipitation at Vancouver, 

Wash., maximum stage determined at several points near gage, by silt 

deposits in the bark of cedar trees and by stain on the bark of trees. Stage 

60.0 feet according to the records of early settlers and also according to later 

checks by a United States Geological Survey engineer (discharge, about 

300,000 second-feet by comparison with flow at The Dalles).

November 16, 1896, maximum stage determined from high-water marks,

54.8 feet (discharge, 185,000 second-feet).

November 19, 1897, maximum stage determined from high-water marks,

54.9 feet (discharge, 190,000 second-feet).

Minimum stage recorded, 32.3 feet September 29-30 and October 10-11, 

1915 (discharge, 2,830 second-feet).5

ICE. Stage-discharge relation seldom affected by ice.

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

to 8 per cent at high stages. Amount determined at each visit and added 

to flow measured on main channel. Flow in Beatty's slough is included 

with the flow in the main channel in the records of this station.

REGULATION. None.

ACCURACY. Stage-discharge relation changes frequently. Previous rating 

curves found to be in error, primarily due to insufficient information regarding behavior of river during floods. Daily discharge from beginning of 

record revised in this report from rating curves based on slope determinations, high-water marks, and a mass of data obtained from old residents

75,000 second-feet and poor above that discharge, except for peak discharges 

of 1917 and 1921 which are fair.

THUWDEB GREEK WEAR MARB1EMOUWT, WASH.

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, 1922.

GAQE. 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 at 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 recorded during yeai from highwater marks in well, 15.5 feet about 4.30 p. m. December 12 (discharge, 

9,720 second-feet); minimum stage, from recorder, 2.88 feet from March 

14-17 (discharge, 71 second-feet). Discharge probably less in January and 

February when stage-discharge relation was affected by ice.

ACCURACY. Stage-discharge relation changed December 12; affected by ice 

December 20-29 and January 18 to February 13. Rating curves fairly 

well defined up to 2,000 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 heights 

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.

COOPERATION. Maintained in cooperation with city of Seattle.

CHANNEL AND CONTROL. Bed composed of gravel and boulders. Banks high; 

not subject to overflow. Low-water control about 150 feet below gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 14.65 feet at 4 p. m. December 12 (discharge, 23,000 secondfeet); minimum stage, from recorder, 2.49 feet from 11 a. m. to 1 p. m., 

February 5 (discharge, 193 second-feet).

1918-1922: Maximum stage recorded, that of December 12, 1921. Minimum stage recorded, from water-stage recorder, 2.12 feet at 3 a. m. October 

7, 1919 (discharge, 173 second-feet).

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

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed December 12; slightly affected 

by ice January 18-19. Rating curve used prior to change well defined below 

4,000 second-feet; latest curve fairly well defined. Intake partially clogged 

for an indefinite period during summer. Operation of water-stage recorder 

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

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

height determined graphically from automatically made record or, for 

days when there was considerable variation in stage, by averaging results 

obtained by applying mean gage heights for shorter intervals. Records 

good.

COOPERATION. Station maintained in cooperation with American Nitrogen 

Products Co.

BAKER RIVER BELOW ANDERSON CREEK, NEAR CONCRETE, WASH.

LOCATION. In SE. M sec. 30, T. 37 N., R. 9 E., Whatcom County, 350 feet below 

Anderson Creek, a quarter of a mile above Baker River ranger station, and 

11 miles above Concrete.

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

RECORDS AVAILABLE. September 10, 1910, to September 30, 1922.

GAGE. Stevens continuous water-stage recorder referred to inside staff gage, 

on left bank; installed September 24, 1915; inspected by Charles Bagnell. 

For description of previous gages see 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, subject to overflow at about 

11-foot stage.

EXTREMES OP DISCHARGE. Maximum stage recorded during year from waterstage recorder, 10.8 feet at 4 p. m. December 12 (discharge, 23,600 secondfeet) ; minimum stage, from recorder, 1.83 feet at 6 p. m. March 1 (discharge, 

390 second-feet).

1910-1922: 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 

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

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during flood of December 12. 

Rating curve used prior to change well defined between 700 and 10,000 

second-feet; that used after change fairly well defined below 3,000 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 determined graphically from automatically 

made record or, for a few days when range of stage was considerable, by 

averaging results obtained by applying mean gage heights for shorter 

intervals. Prior to December 12 records of discharge below 10,000 secondfeet excellent; good thereafter.

COOPERATION. Station maintained in cooperation with United States Forest 

Service.

UPPER COLUMBIA RIVER BASIN. 83 

COLUMBIA RIVER AT VERNITA, WASH.

LOCATION. In sec. 11, T. 13 N., R. 24 E., at Richmond ferry, half a mile north 

of Vernita and 6 miles below Priest Rapids, Benton County.

DRAINAGE AREA. 95,500 square miles. (Areas in the United States measured 

on topographic maps and on maps issued by United States Geological 

Survey, scale 1 :500,000. Areas in British Columbia measured on Department of the Interior railway-belt maps, scale 1:500,000; Department of 

Mines, West Kootenai sheet, scale 1:253,440; and Department of Lands 

map, scale 1:1,125,000.)

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, 1922; daily discharge ascertained from May 1, 1913, to 

September 30, 1922. 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 description of previous gages see 

Water-Supply 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 severey-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 mile below gage; apparently 

permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 28.8 feet, 

from June 15 to 18 (discharge, 424,000 second-feet); minimum stage recorded, 0.21 foot on March 1 (discharge, 27,200 second-feet; discharge 

estimated at 27,200 second-feet for February 28, while stage-discharge 

relation was affected by ice.

1913-1922: 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 14, 1919, when stage-discharge relation was affected by ice.

Maximum stage recorded at Wenatchee by United States Weather Bureau 

and Great Northern Railway Co., 58 feet, June 7, 1894 (estimated discharge 

by extending rating curve, 710,000 second-feet). The Chief of Engineers, 

United States Army,6 gives a crest elevation of the 1894 flood and an elevation of zero on the Weather Bureau gage from which it appears that the 

gage height was 59.8 feet (estimated discharge, 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.

DIVERSION. Some water diverted for irrigation.

REGULATION. None.

« U. S. Army Kept., 1895, pt. 5, p. 3542.
84 STJBFACE WATEB SUPPLY, 1922, PAET XII A.

ACCURACY. Stage-discharge relation permanent; affected by ice January 4 to 

February 19 and February 22-28. Gage read to hundredths twice daily. 

Daily discharge ascertained by applying mean daily gage heights to rating 

table. Records excellent except for periods of ice effect.

COOPERATION. Maintained in cooperation with the Washington Irrigation & 

Development Co.

KOOTENAI RIVER BASIN. 

KOOTENAI RIVER AT LIBBY, MONT.

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

Northern Railway station at Libby, Lincoln County.

DRAINAGE AREA. 11,000 square miles.

RECORDS AVAILABLE. October 13, 1910, to September 30, 1922.

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

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

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

prior to change reduced to new datum.

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 OP DISCHARGE. Maximum stage reported during year, 13.45 feet 

June 6 (discharge, 69,200 second-feet); minimum stage, January 17 (discharge measurement, 2,190 second-feet).

1910-1922: 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 seriously affected by ice.

DIVERSIONS. None of importance.

ACCURACY. Stage-discharge relation permanent except when affected by ice. 

Rating curve well defined 2,500 to 40,000 second-feet and fairly well defined 

above 40,000 second-feet. Gage usually read to hundredths once daily 

except Sunday. Daily discharge ascertained by applying daily gage height 

to rating table. Discharge interpolated for days of no gage reading. Records 

good.

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. 

Stage of zero flow determined September 29, 1922, gage height 1.9 feet.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 7.8 feet at 

7.30 a. m. June 4 (discharge, 5,010 second-feet); minimum discharge occurred 

during winter when stage-discharge relation was affected by ice.

1911-1916; 1919-1922: Maximum stage recorded, 11 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 

probably lower in December, 1919, and in January and February, 1922, 

when stage-discharge relation was affected by ice.

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

observer's notes and weather records.
88 SURFACE WATER SUPPLY, 1922, PART XII A.

ACCURACY. Stage-discharge relation permanent; affected by ice November 

20-26 and December 17 to March 11. Rating curves well denned below 

4,500 second-feet. Gage read to hundredths twice daily. Daily discharge 

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

good except for period when stage-discharge relation was affected by ice.

CLARK FORK NBAS PLAINS, MOOT.

LOCATION. On lot 7, sec. 7, T. 19 N., R. 26 W., at Cooper's ferry, 3 miles above 

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

DRAINAGE AREA. 19, 900 square miles.

RECORDS AVAILABLE. October 28, 1910, to September 30, 1922.

GAGE. Barratt & Lawrence water-stage recorder; inspected by A. L. Steiner.

DISCHARGE MEASUREMENTS. Made from cable.

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

flood stages. Banks high and are not overflowed. Bed is practically 

permanent. No well-defined control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 17.2 feet at 

11 a. m. June 9 (discharge, by indirect method, 114,000 second-feet); minimum flow, February 5-7 (stage-discharge relation affected by ice; discharge 

computed 4,890 second-feet).

1910-1922: Maximum stage recorded, 17.9 feet June 5, 1913, and July 2, 

1916 (discharge, 115,000 second-feet); minimum stage, during open water, 3.7 

feet several times during October and November, 1919 (discharge, 4,890 

second-feet); lower flow probably occurred during the ice periods.

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

DIVERSIONS. Numerous diversions are made for irrigation from the headwaters 

of Clark Fork and tributaries to Flathead River.

REGULATION. Flathead Lake furnishes a natural but uncontrolled regulation 

for part of flow.

ACCURACY. Stage-discharge relation not permanent; shifted June 17; affected 

by ice December 19 to March 18. Two rating curves used during year, one 

applicable October 1 to June 16 well defined below 60,000 second-feet and 

fairly well defined above, the other applicable June 17 to September 30 

is fairly well defined below 90,000 second-feet. Daily gage heights obtained 

by inspection of graph of Barrett & Lawrence gage. Daily discharge for 

open channel ascertained by applying mean daily gage height to rating 

table except June 6-16, when indirect method was used. Record for open 

water, good; others, fair.

from extended rating curve, lt)4 second-feet); minimum discharge, 0.6 

second-foot September 7, 1919.

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. United States Bureau of Reclamation Poison A canal diverts 

water between power house and gage.

UEGULATION. Operation of power plant materially affects flow, maximum 

effect is during low-water period.

ACCURACY. Stage-discharge relation affected by ice; otherwise practically 

permanent during year. Rating,, curve well defined between 2 and 30 

second-feet. Daily gage heights determined by straight-line method from 

graph of Stevens eight-day recorder October 1 to November 17, April 22 to 

June 24, and July 22 to September 30. Daily discharge ascertained by applying mean daily gage height to rating table and adding flow of canal or 

by reducing total kilowatt-hours for day to equivalent second-feet for 

24 hours. Records fair.

122 SURFACE WATER SUPPLY, 1922, PART XII A. 

SULLIVAN CREEK NEAR METAUKE FAILS, WAS!.

LOCATION. In sec. 30, T. 39 N., R. 44 E., one-eighth of a mile below Outlet 

Creek, half a mile below Sullivan Lake, and 4 miles east of Metaline Falls, 

Pend Oreille County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 16, 1912, to September 30, 1922.

GAGE. Inclined staff on left bank installed October 27, 1919; read by A. J. 

McDougall. Previous gages as follows: May 16, 1912, to September 20, 1917, 

vertical staff on right bank directly opposite present gage and at same datum; 

September 21, 1917, to May 17, 1919, vertical staff in four sections at site 

and datum of present gage. Temporary staff gage installed May 25, 1919, 

and read until October 26, 1919. Readings on temporary gage referred to 

datum of previous gage.

DISCHARGE MEASUREMENTS. Made by wading or from cable 40 feet below gage.

CHANNEL AND CONTROL. Bed composed of cobblestones and coarse gravel; 

shifting. Banks high and not subject to overflow. Gradient steep. Stage 

of zero flow according to measurements made October 2, 1920, gage height 

 0. 3 foot.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.82 feet at 

7.30 a. m. June 4 (discharge, 850 second-feet); minimum stage recorded, 0.80 

foot April 17-19 (discharge, 41 second-feet).

1912-1922: Maximum stage recorded, 4.2 feet June 2, 1913 (discharge, 

1,650 second-feet); minimum stage recorded, that of April 17-19, 1922.

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

winters.

DIVERSION. 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 permanent; not affected by ice. Rating 

curve fairly well defined, up to 1,500 second-feet. Gage read to hundredths 

once daily. Surge makes it difficult to read gage accurately. 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 SPOKANE, WASH.

LOCATION. In sec. 13, T. 25 N., R. 42 E., about opposite Coehrane 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 (revised; measured by engineers of Washington Water Power Co. on maps of Spokane River drainage basin, scale 

one-half inch to the mile, compiled from best available sources).

RECORDS AVAILABLE. April 1, 1891, to September 30, 1922.

GAGE. Stevens continuous water-stage recorder, on right bank set to mean 

sea-level datum, 1 mile below Monroe Street Bridge; installed May 9, 1921, 

and used since July 1, 1921. Approximate elevation of present gage datum 

1,700 feet above sea level.

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; set at different datum but to read same as previous gage. 

March 31, 1904, to March 1, 1907, a vertical staff at the Mission Street 

Bridge, 3.4 miles above present site. March 2, 1907, to July 23, 1911, 

combined inclined and vertical staff gage at Martha Street, 4 miles above 

present site. July 24, 1911, to July 30, 1915, several gages, set to mean 

sea-level datum, located 500 feet 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, 19J15, to June 30, 1921, Stevens 

continuous water-stage recorder, set to mean sea-level datum, at same 

location near Washington Water Power Co.*s steam plant. At time of 

each relocation simultaneous readings were obtained between the old and 

new gages so that the relation of stage at the different sites was established.

DISCHARGE MEASUREMENTS. Made from cable at gage.

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

at all stages. Control is well-defined riffle one-fourth of a mile below gage; 

should be permanent. Stage of zero flow estimated at gage height 14.5 

feet on October 7, 1922.

EXTREMES OP DISCHARGE. Maximum stage recorded during year from waterstage recorder, 25.3 feet at 2.30 a. m. on May 22 (discharge, 26,300 secondfeet); minimum stage from recorder, 17.37 feet at 12.45 p. m. August 13 

(discharge, 1,060 second-feet).

1891-1922: Maximum stage recorded, 12.42 feet May 31, 1894 (discharge, 

49,000 second-feet); minimum discharge, that of August 13, 1922.

ICE. Stage-discharge relation not affected by ice.

DIVERSION. 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. Stage-discharge relation at present site permanent. Rating curve 

well defined. Operation of water-stage recorder satisfactory. Daily discharge October 1 to June 21 ascertained by applying to rating table daily 

mean gage height determined from recorder graph by inspection; discharge 

integrator used June 22 to September 30. Records excellent.

COOPERATION. Gage-height record and some discharge measurements furnished 

by Washington Water Power Co.

SPOKANE EIVEE BASIN. 137

ST. JOE BIVEE AT CALDEB, 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 of Spokane River drainage basin compiled from 

all sources available).

RECORDS AVAILABLE. July 13, 1920, to September 30, 1922; April 14, 1911, to 

September 30, 1912, at station about 2% miles downstream.

GAGE. Stevens continuous water-stage recorder on right bank at ferry landing 

at Calder; installed December 22, 1920; inspected by C. P. Latham. Gage 

at former station April, 1911, to September 30, 1912, was vertical staff on 

right bank 2J^ miles below present site; July 13 to December 21, 1920, 

vertical staff gage at practically same site and datum as present gage. Present gage datum is 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, from waterstage recorder, 87.8 feet at 7 a. m. May 18 (discharge, 17,600 second-feet); 

minimum stage recorded from recorder, 79.00 feet at 2 a. m. November 20 

('discharge, 280 second-feet); discharge may have been lower during winter 

when stage-discharge relation was affected by ice.

1911-1912; 1920-1922: Maximum and"minimum stages occurred during 

climatic year 1922.

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

discharge measurements, observer's notes,* and weather records.

DIVERSIONS. None.

REGULATION. Flash dam at Marble Creek used to store water for flushing 

logs down river during low water. Water released at regular intervals 

during driving season. Operation of dam causes diurnal fluctuation at gage 

of about 1 foot. Duration of effect about 4 hours.

ACCURACY. Stage-discharge relation changed May 18; affected by ice December 

21-25 and January 5 to March 20 and by logs August 11 to September 30. 

Rating curves fairly well defined below 800 second-feet; well defined above. 

Operation of water-stage recorder fairly satisfactory. Daily discharge ascertained by applying to rating table mean daily gage height obtained by inspection from gage-height graph corrected to agree with staff-gage readings. 

Records good above 800 second-feet; otherwise fair except for periods of 

ice and log effect.

COOPERATION. Gage-height record and some discharge measurements furnished by Washington Water Power Co.

Discharge measurements of St. Joe River at Calder, Idaho, during the year ending 

\ Sept. SO, 1922.

DRAINAGE AREA. 420 square miles (measured by engineers Washington Water 

Power Co. on map of Spokane River drainage basin compiled from all 

available sources).

RECORDS AVAILABLE. July 9, 1911, to October 31, 1912, and July 15, 1920, to 

September 30, 1922.

GAGE. Vertical and inclined staffs installed July 15, 1920, on left bank, read by 

Mrs. G. W. Jarmin. July 9, 1911, to October 31, 1912; vertical staff on 

right bank about half a mile downstream.

DISCHARGE MEASUREMENTS. Made by wading or from suspension footbridge 

at railway station.

CHANNEL AND CONTROL. Bed composed of gravel and small boulders. Channel straight for 500 feet below gage. Left bank high; not subject to overflow at gage. Right bank subject to overflow at high stages. Riffle control 

300 feet below gage; shifting at high stages. Stage of zero flow according to 

measurements made August 6 and September 22, 1920, gage height 58.1 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 62.6 feet 

on April 22 and May 5 (discharge, 2,780 second-feet); minimum discharge 

occurred during winter when stage-discharge relation was affected by ice and 

logs; certainly less than 40 second-feet.

1911-1912; 1920-1922: Maximum stage recorded, 66.5 feet at 6 a. m. 

March 18, 1921 (discharge, 8,660 second-feet); minimum discharge probably 

occurred during winter 1921-22.

ICE. Stage-discharge relation seriously affected by ice.

ACCURACY. Stage-discharge relation changed December 1; affected by ice and 

logs November 18, 19, 21-24, 26, 27, December 18 to Apiil 2; affected by 

logs on control June 15 to September 30. Rating eurve used prior to 

December 1, poorly defined; that used after December 1 fairly well defined. 

Gage read to hundredths once daily. Daily discharge ascertained by applying daily gage height to rating table. Records fair October and November; 

good April to June; otherwise poor.

142 SURFACE WATER SUPPLY, 1922. PART XII A.

SPOKANE VALLEY LAND & WATEB 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 gages and half a mile west of 

Post Falls, Kootenai County.

RECORDS AVAILABLE. May 20, 1911, to September 30, 1917; September 6, 1919, 

to September 30, 1922.

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 cross ties 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.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.2 feet 

July 2-21 (discharge, 157 second-feet); no water in canal December 18 

to April 14.

1911-1917 and 1919-1922: Maximum stage recorded, 3.2 feet June 18-22, 

1911 (discharge, 170 second-feet); no water in canal during periods in 

1911, 1912, 1916, 1917, 1919, 1920, 1921, and 1922.

ICE. Stage-discharge relation not affected by ice.

ACCURACY. Stage-discharge relation changed during period of no flow and 

gradually July 1 to September 23; affected by backwater from aquatic 

growth October 1 to December 17, and July 1 to September 30.

Rating curve developed from a series of measurements made during a 

two-day period in 1920 and well defined within limits of use; has been used 

as standard form of curve for this station and curves parallel to this have 

been assumed to result from changes at control indicated by discharge 

measurements. 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 in canal to remain constant, even though the stage of the river 

is subject to considerable daily fluctuation. Daily discharge October to 

June and September 23-30 ascertained by applying daily gage height, 

corrected for backwater, to rating table; shifting-control method used 

July 1 to September 22, 1922. Records 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. 

50 N., R. 5 W. Boise meridian. Water is used for irrigation.

subject to overflow at gage height 4.0 feet; left bank high; not subject to 

overflow. Stage of zero flow, gage height 0.4 foot.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 2.55 feet May 

4 (discharge, 189 second-feet); minimum stage recorded, 0.75 foot September 25 and 26 (discharge, 3.7 second-feet).

1911-1922: Maximum stage recorded, 4.9 feet April 5, 1919, determined 

from leveling to high-water mark (discharge, 483 second-feet); minimum 

stage recorded, that of September 25 and 26, 1922.

ICE. Stage-discharge relation seldom affected by ice.

DIVERSION. Nespelem canal diverts water for irrigation from a point above 

gage. See records for Nespelem canal.

RE GUL ATION. None.

ACCURACY. Stage-discharge relation permanent; affected by aquatic growth 

October 1-17 and June to September. Rating curve well defined. Gage 

read to hundredths once daily. Daily discharge ascertained by applying 

daily gage height to rating table, or by shifting-control method during 

periods when stage-discharge relation was affected by aquatic growth. 

Records below 10 second-feet good; otherwise excellent.

natural inflow to lake); practically no flow when gates in Keechelus reservoif 

dam are closed.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. Flow partly controlled by storage and release of water at Keechelus reservoir. Monthly discharge without storage determined from records 

of stage at reservoir.

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

Gage read twice daily to hundredths. Daily discharge ascertained by 

applying mean daily gage height to rating table. Records good.

174 SUBFACE WATER SWPPlrY, 1922, PART XII A.

KACHESS RIVEB HEAR EASTON, WASH.

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

storage dam, one-fourth of a mile above mouth and 2 miles northwest of 

Easton, Kittitas County.

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

RECORDS AVAILABLE. November 20, 1903, to September 30, 1922.

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 cable 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 discharge recorded during year, 6.17 feet 

on July 20 (discharge, 1,610 second-feet). Practically no flow when gates 

in dam are closed.

1904-1922: 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.

DIVERSION. 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 continuously'-during period gates 

were open; not affected by ice. Rating curve revised for 1922 has been used 

as standard form of curve for this station and changes in control indicated 

by discharge measurements are assumed to yield curves parallel to this. 

Water-stage recorder inspected daily except as noted in footnote to table 

of daily discharge and when gates are closed. Daily discharge for periods 

when gates were open ascertained by shifting-control method. When gates 

were closed leakage estimated from knowledge of governing conditions. 

Records good.

COOPERATION. Complete records furnished by United States Bureau of 

Reclamation.

of Cle Elum Lake, 4 miles northwest of Roslyn, Kittitas County, and 7J^ 

miles northwest of Cle Elum.

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

RECORDS AVAILABLE. October 10, 1903, to September 30, 1922.

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

crib dam; installed October 14, 1913; inspected by 3. G. Giddings. For 

description of previous gages see Water-Supply Paper 442.

DISCHARGE MEASUREMENTS. Made from cab\e about 350 feet below gage or 

by wading.

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

at high water. One channel at all stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 12.50 feet at 1 a. m. December 13 (discharge, 13,300 secondfeet); minimum stage, from recorder, 0.62 foot from 5 p. m. January 29 to 

4.35 p. m. February 2 (discharge, 39 second-feet).

1904-1922: Maximum stage recorded, 14.05 feet at 2 p. m. November 15, 

1906 (discharge, 18,700 second-feet); minimum stage recorded, zero at 6 p. m» 

September 28, 1914 (practically no flow).

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

from records of stage at reservoir.

ACCURACY. Stage-discharge relation changed gradually October 1-5, 31, and 

December 12. Rating curves used October 6-30 and December 12 to 

September 30 well defined; that used October 31 to December 11 fairly 

well defined. Operation of water-stage recorder satisfactory. Daily discharge ascertained by applying mean daily gage height to rating table. 

Shifting-control method used October 1-5. Records good October to 

December; excellent thereafter.

COOPERATION. Complete records furnished by United States Bureau of 

Reclamation.

November 24, 1909; minimum discharge, 202 second-feet at 5 p. m. November 20, 1917, and September 23, 1918.

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

DIVERSIONS. Above all important diversions except Selah Valley and Tietorr 

canals. Diversion through canals added to mean monthly flow to determine natural flow past gage.

REGULATION. Flow partly controlled by storage and release of water atJBurnping Lake. See record for Bumping Lake and table of monthly discharge for 

Bumping River near Nile, Wash.

ACCURACY. Stage-discharge relation changed December 12; slightly affected by 

ice for very few days in January and February. Possibly affectedfduring 

periods of low stage by backwater from wing dam at intake of Wapatox 

canal until after December 12. Effect of backwater probably slight. 

Rating curves well defined. Water-stage recorder inspected daily. Daily 

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

Records good October to February; excellent thereafter.

COOPERATION. Maintained by United States Bureau of Reclamation in cooperation with Pacific Power & Light Co. United States Bureau of Reclamation made discharge measurements and computed discharge.

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

during the year ending Sept. 30, 1922.

~The run-off without ;Storage<and estimated jiataral»dfeeharge*sliGwn in the ;foregoing table 

represent natural yield as nearly as may be computed from stream-flow records. They do not take into 

account depletion due to irrigation above the gaging station amounting to perhaps 6,000 acre-feet a year 

and unmeasured waste above the gaging station on Selah Valley canal which reaches the river below the 

river gaging station. Accordingly the actual natural yield is larger than shown.

LOCATION. A quarter of a mile below spillway of Bumping Lake dam, half a 

mile below outlet conduit through storage dam, H^J 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, 1908; April 27, 190&,"to September 

30, 1922.

GAGE. Stevens water-stage recorder installed June 17, 1913; inspected by J. H. 

Nelson daily. Since June 17, 1913, vertical staff on left bankf one-fourth 

mile below spillway of storage dam*; reconstructed -at- same site and datum 

April 27, 1915. For "description ofprevious gages«e 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 betow gage. Stage 

of zero flow, gage height about 0.3 foot.

EXTREMES OF DISCHARGE. Maximum stage recorded during year froafl waterstage recorder, 4.43 feet at 7 a. m. June 9 (discharge, 1,270 second-feet) ; 

minimum stage from recorder, 1.43 feet at 3.35 p!. m. May 13 (discharge/ 

22 second-feet).

1906 and 1909-1922: 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.

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

curve fairly well defined. Water-stage recorder inspected daily. Daily 

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

for a few days when range in stage was considerable; by averaging result® 

obtained by applying mean gage height for shorter intervals. Records 

fair.

COOPERATION. Complete records furnished by United States Bureau of 

Reclamation.

184 SURFACE WATER SUPPLY, 1922, PART XII A.

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

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

canal, 15 miles above mouth, and 16 miles southwest of Naches, Yakima 

County.

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

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

record); July 5, 1907, to September 30, 1922.

GAGE. Stevens continuous water-stage recorder on right bank about 1,000 feet 

below intake Of Tieton canal; inspected by G. G. Willis. Friez water-stage 

recorder at same site used July 8, 1911, to October 13,1918. For description 

of previous gages see Water-Supply Paper 442.

DISCHARGE MEASUREMENTS. Made from cable about 5QO feet below gage or by 

wading.

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

at high water; gradient steep. One channel at all stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year from waterstage recorder, 8.15 feet at 1.20 a. m. December 13 (discharge, 6,150 secondfeet); minimum stage from recorder, 1.77 feet at 9.20 p. m. August 6 (discharge, 12.5 second-feet).

1907-1922: Maximum stage recorded, that of December 13, 1921; minimum stage from water-stage recorder, 1.55 feet at 6.30 p. m. August 26, 

1920 (discharge, 5 second-feet).

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

DIVERSION. 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 fluctuations during irrigation seasons.

ACCURACY. Stage-discharge relation permanent; slightly affected by ice for 

very few days in January and February. Rating curve well defined. Operation of water-stage recorder satisfactory, except as noted in footnote to 

table of daily discharge. Daily discharge ascertained by applying mean 

daily gage height to rating table. Records fair January and February; 

otherwise good.

COOPERATION. Complete record furnished by United States Bureau of Reclamation.

Discharge measurements of Tieton River at headworks of Tieton canal, near Naches,

highway bridge, 3^ miles southeast of Fort Simcoe, Yakima County, and 5 

miles southwest of White Swan.

DRAINAGE AREA. 124 square miles (measured on PI. I, Water-Supply Paper 369).

RECORDS AVAILABLE. February 27, 1909, to September 30, 1922.

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

ranch house; installed August 19, 1915; inspected by A. B. Morrison. 

Previous gages as follows: February 27,1909, to July 22,1913, chain gage 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 baijk 

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. Banks 

covered with brush; subject to overflow at extremely high water.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 3.70 feet at 6 a. m. May 18 (discharge, 532 second-feet); 

minimum stage from recorder, 0.96 foot at 9 p. m. August 25 (discharge, 2.6 

second-feet).

1909-1922: Maximum discharge recorded, 1,650 second-feet at noon 

May 4, 1916; minimum stage recorded, that of August 25, 1922.

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

records, discharge measurements, observer's notes, and weather records.

DIVERSIONS. Toppenish feeder canal was in operation during entire year. 

Mean daily diversion ranged from 0.4 second-foot to 22 second-feet. 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 in proposed.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent for year; affected by ice November 18-25, January 2-31, February 1-6, and February 28 to March 4. 

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

Daily discharge ascertained by applying to rating table mean daily gage 

height determined by inspection from recorder graph. Records excellent 

except for extremely low water and for periods during which stage-discharge 

relation was affected by ice.

COOPERATION. Gage-height record and some discharge measurements furnished by United States Indian Service.

YAKIMA EIVBE BASIN". 19T

SATUS CREEK BELOW DRY CREEK, NEAR TOPPENISH, WASH:

LOCATION. In sec. 24, T. 9 N., R. 19 E., at dam site 1 mile below mouth of Dry 

Creek and 9 miles southwest of Toppenish, Yakima County.

DRAINAGE AREA. 427 square miles (measured on topographic maps and map of 

Yakima Indian Reservation).

RECORDS AVAILABLE. June 22, 1913, to September 30, 1922.

GAGE. Stevens continuous water-stage recorder on left bank; inspected by H. E. 

and F. L. Larimore and R. S. Skillin.

DISCHARGE MEASUREMENTS. Made from cable or by wading.

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

EXTEEMES OF DISCHARGE. Maximum discharge during year occurred on December 1, when water-stage recorder was not operating; stage and discharge not 

determined. Minimum stage from water-stage recorder, 1.25 feet on September 14-22 (discharge, 9 second-feet).

1913-1922: Maximum stage recorded, 9.15 feet December 22, 1915, fromhigh-water mark in well (discharge, 3,870 second-feet); minimum stagerecorded, 0.28 foot at 10 p. m. August 28 and 4 a. m. August 30, 1915 (discharge, 6.6 second-feet).

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

record, observer's notes, and weather records.

DIVERSIONS. Entire flow of Satus Creek above Lazy Creek is diverted for irrigation during July and August; records for low water in summer show 

run-off of Lazy and Dry creeks and seepage return from upper Satus.

REGULATION. None.

ACCURACY. Stage-discharge relation changed December 1; affected by drift on 

control October 1-24; by ice November 20-24 and January 1 to February 10_ 

Rating curve used prior to change fairly well defined; latest curve well 

defined up to 750 second-feet. Operation of water-stage recorder unsatisfactory through several periods, as indicated in footnote to table of dailydischarge. Daily discharge ascertained by applying to rating table mean 

daily gage height determined from recorder graph by inspection or, for a few 

days when variation in stage was considerable, by averaging results obtained 

by applying mean gage heights for shorter intervals. Shifting-control method 

used October 1-24. Records good except during breaks in gage-height 

record and periods of ice effect.

COOPEEATION. Some measurements and a portion of gage-height record furnished 

by United States Indian Service.
