COLUMBIA RIVER BASIN, 1926

AUTHORIZATION AND SCOPE OF WORK

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

measurements of flow made on streams in the United States during 

the year ending September 30, 1926.

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. Since the fiscal year ending June 30, 1895, 

successive appropriation bills passed by Congress have carrsd the 

following items:

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.

In the execution of the work many private and State organizations 

have cooperated either by furnishing records or by assisting in collecting data. Acknowledgments for cooperation of the first k'nd are 

made in connection with the description of each station affected; 

cooperation of the second kind is acknowledged on page 9.

Measurements of stream flow have been made at about 5,250 

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

the Hawaiian Islands. In July, 1926, 1,730 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 water-supply papers from time to time.

2 SURFACE WATER SUPPLY, 1926, PART XII A

DEFINITION OF TERMS j

v -The1 volume of Water flowing in a stream the "run-off" or "discharge" is expressed in various terms, each of which has become 

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

into two groups (1) those that represent a rate of flow, as second- 

,feet, 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 secord-feet, secondfeet per square mile, run-off in inches, acre-feet, and irillions of cubic 

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 mite" is the average number of cubic 

feet of water flowing per second from each square mile cf 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, h 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 channel below the gage which determines the stage-discharge 

relation at the gage. It should be noted that the cc^trol may not 

be the same section or sections at all stages.

The "point of zero flow" for a 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, 1925, and ending September 30, 1926. At th<? 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 brer,k-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
EXPLANATION OF DATA , 6

the run-off for the year beginning October 1 is practically all derived 

from precipitation witbin that year.

The base data collected at gaging stations consist of records of 

stage, measurements of discharge, and general information used to 

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

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

that gives a continuous record of the fluctuations. Measurements of 

discharge are made with a current meter. The general methods are 

outlined in standard textbooks on the measurement of river discharge. A typical gaging station, equipped with water-stage recorder 

and measuring cable and car, is shown in Figure 1,

FIGURE 1. Typical gaging station

From the discharge measurements rating tables are prepared that 

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

heights to these rating tables gives the discharge from which the 

monthly and yearly mean discharge is 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 condition 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
4 SURFACE WATER SUPPLY, 1926, PART XII A

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 means of the gage heights read each 

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

fluctuation the discharge obtained from the rating table and the 

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

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

mean daily discharge may be obtained by averaging discharge at 

regular intervals during the day or by use of 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 per second during the month. On this average flow are 

based computations recorded in the remaining columns, which are 

defined on page 2.

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 the (1) permanence of the stage-discharge relation, (2) precision with which the discharge rating curve is defined, (3) refinement 

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

applying daily gage 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 con-
 TjBLICATIONS O

cerning 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" published by the Geological Survey in earlier reports should be used with 

caution because of possible inherent but unknown sources of error.

Many gaging stations on streams in the irrigated areas of the United 

States are situated above most of the diversions from those streams, 

and the discharge recorded does not show the water supply available 

for further development, as prior appropriations below the stations 

must be satisfied first. To give an idea of the amount of prior appropriations, a paragraph on diversions is presented in each station 

description. The figures given can not be considered exact but 

represent the best information available.

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

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

estimates; the tables of daily discharge allow more detailed studies 

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

the observations in each succeeding year may be expected to throw 

new light on data previously published.

PUBLICATIONS

Investigation of water resources by the 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 investigation 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.

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 suppry published from 1899 to 

1926. The data for any particular station will be found in the 

reports covering the years during which the station was maintained. 

For example, data for Machias River at Whitneyville, Me., 1903 to 

1921, are published in Water-Supply Papers 97, 124,165, 201,241,261, 

281, 301, 321, 351, 381, 401, 431, 451, 471, 501, and 521, which contain records for the New England streams from 1903 to 1921. Pesults 

of miscellaneous measurements are published by drainage basins.

CHANNEL AND CONTROL. Banks high, not subject to overflow. Gradient steep. 

Control for low and medium stages is solid rock; for higl stage, solid rock 

an^d boulder riffle.

EXTREMES OF DISCHARGE. Maximum stage recorded durinf period May 19, 

1925, to September 30, 1926, 20.0 feet about 6.30 a. m. December 11 (discharge, 8,350 second-feet); minimum stage, 0.27 feet at 4.55 p. m. October 

23 and 8.50 a. m. October 24 (discharge, 80 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during high wMer December 11. 

Rating curves well defined. Staff gage read to hundredth s twice daily until 

November 6. Operation of water-stage recorder satisfactory, except as 

noted in footnote to table of daily discharge. Daily discharge prior to 

November 7 ascertained by applying to rating table m°.an of twice daily 

readings of staff gage, after that date by applying to ratine; table mean daily 

gage height obtained by inspecting gage-height graph or, for days of considerable variation in stage, by averaging discharge for shorter intervals. 

Records good.

COOPERATION. Many discharge measurements furnished by city of Aberdeen.

SKOKOMISH. RIVER BASIN 

NORTH FORK OF SKOKOMISH RIVER BELOW STAIRCASE RAPIDS, NEAB HOODSPORT, WASH.

LOCATION. in SW. % sec. 3, T. 23 N., R. 5 W., 300 feet belov Staircase Rapids, 

2 miles above Dry Creek, and 10J4 miles northwest of Hoodsport, Mason 

County.

DRAINAGE AREA. 60 square miles (measured on city of T~,coma's Cushman. 

power project map).

RECORDS AVAILABLE. July 30, 1924, to September 30, 1926.

GAGE. Stevens continuous water-stage recorder on right b-Mik, inspected byemployees of city of Tacoma.

CHANNEL AND CONTROL. Bed composed of gravel; control is well-defined riffle 

in gravel and angular boulders; will shift only during high stages. Gage 

height of zero flow, according to measurement made September 12, 1924,. 

gage height 0.2 foot ±0.1 foot.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.8 feet at 

4 a. m. December 11 (discharge, 4,250 second-feet); minimum stage, 1.25- 

feet from noon September 14 to 5 a. m. September 15 (discharge, 28 secondfeet).

1924-1926: Maximum stage recorded, 6.88 feet, probably some time February 2, 1925, while recorder was not operating (discharge, 4,400 second-feet); 

minimum flow that of September 14 and 15, 1926.
SKOKOMISH RIVER BASIN 25

'"CE. Stage-discharge relation slightly affected by ice during severe winters; 

discharge estimated from weather records.

T)IVEKSIONS. None.

REGULATION. None.

ACCUKACY. Stage-discharge relation practically permanent except as affected by 

trash on control September 1-30; not affected by ice. Rating curve fairly 

well denned. Operation of water-stage recorder satisfactory except that 

partial clogging of intake pipe during late summer caused water st^ge in 

well to lag behind, that in river. This caused slight uncertainty in daily 

records for periods of rapidly changing stage but probably had little or no 

effect on monthly mean discharge. Daily discharge ascertained by applying to rating table mean daily gage height obtained from recorder graph by 

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

discharge for shorter intervals. Records good.

SOUTH FORE OF SKOKOMISH RIVEB NEAR POTIATCH, WASH.

LOCATION. In NW. % sec. 22, T. 22 N., R. 5 W., at canyon head, 2 miles 

below Brown Creek and 1% miles west of Potlatch, Mascn County.

DRAINAGE AREA. 68 square miles (measured on map of Skokomish River 

watershed of city of Tacoma's Cushman power project).

RECORDS AVAILABLE. October 1, 1923, to September 30, 1926.

GAGE. Stevens continuous water-stage recorder on right bark, about 300 feet 

below canyon head; inspected by employees of city of Tacoma.

DISCHARGE MEASUREMENTS. Made from cable about 75 feet above gage or 

by wading.

CHANNEL AND CONTROL. Channel winding, bed composed of light gravel to 

heavy boulders. Banks high and not subject to overflow. Control varies 

with stage; for low water it is of light gravel, shifting; for medium and high 

stages, heavy boulder riffles, shifting at high stages only.

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

5 a. m. December 11 (discharge, 4,560 second-feet); minimum stage, 1.22 

feet from 1 to 10 a. m. September 15 (discharge, 38 second-feet).

1924-1926; Maximum stage recorded, 14.86 feet January 31, 1924 (discharge, from extension of rating curve, 9,950 second-feet); minimum discharge, that of September 15, 1926.

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

Flow estimated from gage height and weather records.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed for low water December 12; not 

affected by ice. Rating curves fairly well defined. Operation of waterstage recorder satisfactory. 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 discharge for intervals of the day. Records good.

30 SURFACE WATER SUPPLY, 1926, PART I'll A

NISQUALLY RIVER BASIN 

NISQTJALLY RIVEK NEAR IA GKANDE, WASH.

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

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

Pierce County.

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

National Park; map of Rainier National Forest, edition of 1918; and pi. 4, 

Water-Supply Paper 313).

RECORDS AVAILABLE. October 1, 1919, to September 30, 1926. September 5, 

1906, to October 31, 1911, fragmentary.

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

vertical staff on left bank at head of low-water control for use during periods 

of low water when silt interferes with normal stage-discharge relation. 

Also Stevens long-distance recorder on right side of Tacoma power conduit, 

750 feet below head gate, and a staff gage in pool behind diversion dam. 

Recorders inspected and gages read by head-gate attendants.

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

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

Considerable amount of glacial silt is deposited during summer, causing 

control to change temporarily.

EXTREMES OF DISCHARGE. Maximum combined daily discharge of river and 

Tacoma power conduit during year, 5,490 second-feet December 23; minimum combined daily discharge during year, 184-second-feet, November 5. 

1920-1926: Maximum combined daily discharge, 16,700 second-feet 

December 12, 1921; minimum combined daily discharge recorded November 

5, 1925.

ICE. Stage-discharge relation not affected by ice.

DIVERSION. City of Tacoma diverts water 1,200 feet above gage for development of power. Discharge is computed from determination of combined 

flow of river and power conduit.

ACCURACY. River and power conduit rated separately. StagiB-discharge relation 

for river station affected by silt on control and in channe1 during low water. 

Rating curves for normal control conditions well defined. Operation of 

water-stage recorders unsatisfactory for long periods. Automatically 

recorded gage heights supplemented by one daily reading on gage at control 

during low water and by 12 daily readings on staff gage behind diversion 

dam. Accuracy of power conduit records discussed o^ page 34. Daily 

discharge determined by combining results obtained for river and for power 

conduit. Records of combined flow good.

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

32 SURFACE WATER SUPPLY, 1926, PART XII A

LITTLE NISQUALLY RIVER NEAR AIDER, WASH.

LOCATION. In NW. % sec. 16, T. 15 N., R. 4 E., in Thurston County, 1,500 feet 

above mouth, 3,000 feet from diversion dam of city of Tacoma's power plant, 

and \% miles southwest of Alder, Pierce County.

DEAINAGE AREA. 28.5 square miles (measured on Forest Service map).

RECORDS AVAILABLE. August 1, 1920, to September 30, 1926.

GAGE. Stevens water-stage recorder on left bank; installed April 16, 1921; 

inspected by employees of city of Taccma.

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 in riffle.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.15 feet from 

5 to 7 a. m. December 23 (discharge, 975 second-feet); minimum stage, 

0.58 foot July 17 (discharge, 0.9 second-foot).

1920-1926: Maximum stage recorded 6.4 feet at 3 p. ir. January 7, 1923 

(discharge, 2,220 second-feet); minimum discharge, that of July 17, 1926.

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

estimated from discharge measurements, observer's notes, and weather 

records.

DIVERSIONS. None.

REGULATION. Effect of operation of flash dam above gage for flushing logs 

down river is noticeable at gage; amount of storage sir all. Duration of 

effect at gage only a few hours at extreme low water.

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

21, and December 23; not affected by ice. Logs in channel and on control 

caused uncertainty as to amounts of backwater present between dates of 

measurements. Rating curves used October 6 to December 22 poorly 

denned; that used December 23 to September 30 fairly well denned. Operation of water-stage recorder satisfactory except as noted in footnote to 

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

table mean daily gage height obtained from recorder graph by inspection; 

shifting-control method used October 1-5. Records fair.

PUYALLUP EIVEE BASIN 39

PUYALLUP EIVEE AT PUYALIUP, WASH.

LOCATION. In NE. % sec. 20, T. 20 N., E. 4 E., 1 mile northwest of Pryallup, 

Pierce County, three-fourths mile above Clark Creek, and 3J^ mile? below 

mouth of Stuck River.

DRAINAGE AREA. 914 square miles (measured on pis. 4 and 11, Water-Supply 

Paper 313).

RECORDS AVAILABLE. May 1, 1914, to September 30, 1926.

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

1919; inspected by C. J. Phillips.

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, 9.40 feet at 

3.20 p. m. December 23 (discharge, 15,800 second-feet); minimum discharge,. 

982 second-feet at 8.45 a. m. October 20.

1914-1926: Maximum stage recorded, 34.15 feet 1 at 4.45 p. m. December 18, 1917 (discharge, 40,500 second-feet); minimum stage, 17.36 feet * 

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

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Two hydroelectric plants owned by the Puget Sound Power & 

Light Co. divert water above the 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, a tributary of Puyallup River 

above the gaging station.

REGULATION. See "diversions."

ACCURACY. Stage-discharge relation changed frequently. Well-definec1 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 define curves parallel to this. Operation of waterstage recorder satisfactory except as noted in footnote to table of dr.ily discharge. Daily discharge ascertained by applying to rating table mer.n daily 

gage height obtained by inspecting recorder graph and corrected as to time 

and amount of shift in accordance with results of discharge measur3ments_ 

Records good.

PUYALLUP RIVER BASIN 41 

WHITE RIVER AT BUCKIEY, WASH.

LOCATION. River gage in SE. }i sec. 34, T. 20 N., R. 6 E., at Northern Pacific 

Railway bridge; flume gage in sec. 35, T. 20 N., R. 6 E., on left side of White 

River, half a mile above Northern Pacific Railway crossing; both about a 

mile northeast of Buckley, Pierce County.

DRAINAGE AREA. 424 square miles (measured on pi. 11, Water-Supply Paper 313).

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

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

18, 1913, to September 30, 1926.

GAGE. Stevens 8-day water-stage recorder on left bank of river 40 feet below 

railway bridge at end of concrete wall protecting abutment of bridge; 

installed January 9, 1917; and Stevens long-distance recorder with transmitter 

at stilling well on right side of flume 800 feet below head gate and recorder in 

gate house, installed January 12, 1918. Recorders inspected by employees 

of Puget Sound Power & Light Co.

DISCHARGE MEASUREMENTS. Measurements of river made by wading or from 

railway bridge; measurements of flume made from footbridge 8 feet below 

flume gage.

CHANNEL AND CONTROL. River bed composed of small boulders and gravel; 

shifting. Gradient steep. One channel prior to flood of January 23, 1919; 

two channels after the flood. 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. Flume 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 combined daily discharge of river and 

flume, 5,430 second-feet December 23; minimum combined daily discharge, 

342 second-feet October 9.

1899-1901, 1911, and 1913-1926: Maximum daily discharge including 

flume, 18,100 second-feet December 18, 1917; minimum daily disci irge including flume, 342 second-feet October 9, 1926.

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

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

Combined discharge is computed from separate determinations of flow of 

river and flume.

ACCURACY/ River and flume rated separately. Stage-discharge relation of both 

river and flume changed continuously throughout year. Standard form of 

rating curves fairly well defined, and changes in control indicated by frequent 

discharge measurements have been assumed to yield curves parallel to standard forms. Operation of water-stage recorders satisfactory. Daily discharge 

determined by shifting-control method, combining results obtained for river 

and for flume. Records good.

COOPERATION. Complete records furnished by Puget Sound Power & Light Co.

March 24, 1901, to April 30, 1912, at intake of Seattle water-supply system, 

1% miles below present gage. Early records not exactly comparal^e 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 near 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.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 7.56 feet at 9 p. m. January 5 (discharge, 1,720 secondfeet) ; minimum discharge probably occurred sometime October 15-26, when 

stage was below intake to stilling well.

1914-1926: Maximum stage, from recorder, 13.55 feet at 10 p. m. December 29, 1917 (discharge, 7,500 second-feet); minimum discharge, 162 secoiidfeet at 1 a. m. October 15, 1914. Discharge may have been lower sometime 

October 15-26, 1925, when water was below intake to stilling well.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None above the station. (See Cedar River at Cedar Falls Wash.)

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 permanent. Rating curve well denned 

between 200 and 7,000 second-feet. Operation of water-stage recorder 

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

discharge ascertained by use of discharge integrator or by applying to rating 

table mean daily gage height determined from gage-height graph by inspection. Records excellent.

The following discharge measurements were made: 

October 2, 1926: Gage height, 4.39 feet; discharge, 234 second-feet. 

May 13, 1926: Gage height, 5.05 feet; discharge, 411 second-feet. 

August 30, 1926: Gage height, 4.28 feet; discharge, 203 second-feet.

HECORDS AVAILABLE. June 1 to September 30, 1926; May 1, 1898, to July 12, 

1899; January 1 to July 16, 1900; September 14, 1902, to July 31, 1904, 

at a station 300 feet below the mouth of South Fork. Mean montl ly records at present station are comparable with sum of flow shown by records 

of North, Middle, and South Forks of Snoqualmie River near North Bend, 

available August, 1907, to September 30, 1926.

 GAGE. Friez water-stage recorder on left bank one-eighth mile below Snoqualmie Falls; inspected by employees of Puget Sound Power & Light Co.

DISCHARGE MEASUREMENTS. Made from suspension bridge half a mile below 

gage.

 CHANNEL AND CONTROL. Channel is straight for some distance above and below

gage and is strewn with huge boulders, which with heavy boulder riffle act

as control. Banks high, not subject to overflow. 

EXTREMES OF DISCHARGE. Maximum stage recorded June 1 to September 30,

1926, 6.44 feet, at 3 a. m. September 22 (discharge, 5,220 second-feet);

minimum stage, 0.67 foot at 7.30 a. m. July 8 (discharge, 320 second-feet). 

1898-1899, 1900, 1902-1904, 1926: Maximum discharge, 24,400 second-feet

January 3, 1903; minimum discharge, that of July 8, 1926.

Records of the combined flow of three forks at and near North B^nd for

1907-1926 indicate that a discharge probably in excess of 32,000 second-feet

occurred December 12, 1921; discharge may have been greater in November,

1909, and November, 1911; probable minimum discharge for th<. same

period, 223 second-feet on October 23, 1925. 

ICE. Stage-discharge relation not affected by ice. 

DIVERSIONS. Entire low-water flow diverted through power plant but returned

to river above gage.
54 SURFACE WATER SUPPLY, 1926, PART XII A

REGULATION. Low dam at head of falls creates sufficient pondage to equalizediurnal fluctuation and to allow regulation to meet power demands during 

low-water period.

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

defined between 500 and 7,500 second-feet. Operation of water-stage 

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

Operation of power plant causes large fluctuation in flow. Daily discharge 

ascertained by averaging results obtained by applying mean gage heights 

for short intervals to rating table. Records good.

COOPERATION. Complete record furnished by Puget Sound Power & Light Co.

1918-1926: Maximum stage, from high-water mark in well, 11.7 fe^t December 12, 1921 (discharge, 10,400 second-feet); minimum stage, that of 

August 15-17, 1926.

~CE. Stage-discharge relation affected by ice during severe winters; flow 

estimated from discharge measurements, observer's notes, and weather 

records.

DIVERSIONS. None.

"?,E GULATI ON . None.

ACCURACY. Stage-discharge relation changed at high water October 26 and 

December 22-23; not affected by ice. Rating curve used prior to first 

change fairly well denned; curves used after October 26 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 by inspection o* gage 

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

discharge for intervals of the day. Records fair.

62 SURFACE WATER SUPPLY, 1926, PART XII A

SKAGIT RIVER NEAR MARBLEMOITNT, WASH.

LOCATION. In SE. }{ sec. 21, T. 37 N., R. 12 E., at city of Seattle power camp, 

Whatcom County, one-fourth mile above Newhalem Creek, 6J£ miles below 

Stetattle Creek, and 16 miles above Marblemount.

DRAINAGE AREA. 1,160 square miles. Area in Canada, 3?0 square miles; 2 

area in United States, 770 square miles, measured on Washington National 

Forest maps.

RECORDS AVAILABLE. December 21, 1908, to May 23, 1914; October 1, 1920, to 

September 30, 1926.

GAGE. Stevens water-stage recorder, installed June 5, 1923, on right bank 

about 300 feet below suspension footbridge and trail to Newhalem Creek 

power plant; inspected by F. E. Davis. Present gage datum 400 feet, 

United States Geological Survey datum.

DISCHARGE MEASUREMENTS. Made from suspension bridge and from measuring 

cable at gage.

CHANNEL AND CONTROL. Right bank high, not subject to overflow; left bank 

gently sloping and wooded, overflowed at extremely high stage. Channel 

straight for several hundred feet above and for long distance below gage. 

Control is gravel and boulder riffle; will shift at high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 85.68 feet at 

2 a. m. April 30 (discharge, 9,220 second-feet); minimum stage, from recorder, 

79.50 feet at 2 p. m. January 31 (discharge, 400 second-feet).

1908-1914, 1920-1926: Maximum stage recorded, 94.2 feet at 8 p. m. 

December 12, 1921 (discharge, 60,000 second-feet); minimum stage, that of 

January 31, 1926.

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

flow estimated from observer's notes and weather records.

DIVERSIONS. Seattle municipal power plant diverts water directly from river 

about 3 miles above the gage, through a pressure tunnel, and returns it to the 

river at the plant just above the gage. Entire low-water flow may be carried 

through the plant.

REGULATION. Daily flow partly controlled at very low water by storage and 

release Qf water at tunnel intake to accommodate requirements of power 

plant.

ACCURACY. Stage-discharge relation changed April 30; not affected by ice. 

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

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

determined by use of discharge integrator except for high water, when daily 

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

determined from recorder graph by inspection. Records excellent.

SKAGIT EIVER NEAR CONCRETE, WASH.

LOCATION. In sec. 16, T. 35 N., R. 8 E., at dalles 2 miles below mouth of 

Baker River and 2,4 rniles southwest of Concrete, Skagit County.

DRAINAGE AREA. 2,700 square miles. Area in United States, 2,310 square 

miles (measured on topographic maps and Washington National Forest 

map, edition of 1922). Area in British Columbia, 390 square mile?.3

8 White, A. V., Water powers of British Columbia, p. 483, Conservation Comm. Canada.
64 SURFACE WATER SUPPLY, 1926, PART I'll A

RECORDS AVAILABLE. September 15, 1924, to September 30, 1926. Flood 

peaks only as noted under "Extremes of discharge."

GAGE. Since December 10, 1924, Stevens continuous recorder in concrete house 

over stilling well, on right bank at the dalles. Gage datum, 163 feet above 

sea level.

DISCHARGE MEASUREMENTS. Made from cable three-fourths mile below gage.

CHANNEL AND CONTROL. Boulder riffle below canyon for low stages; rock canyon 

forming the dalles, for high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 13.6 feet at 

12.15 p. m. December 23 (discharge, 51,600 second-feet); minimum discharge probably occurred during the period October 1-24, 1925, when 

recorder was not operated and gates in Baker River Dam were closed for 

the first time; discharge not determined but probably less than 2,160 secondfeet.

1924-1926: Maximum stage recorded, 19.75 feet at 1 p.m. December 12, 

1924 (discharge, 92,500 second-feet); minimum discharge probably occurred 

during period October 1-24, 1925.

High-water marks at gage height 56.6 feet indicate a flood of 500,000 

second-feet about 1815. Records of other floods prior to establishment of 

station are given in Water-Supply Paper 612.

DIVERSIONS. Water is diverted for the operation of Seattle's municipal power 

plant in sec. 21, T. 37 N., R. 12 E., and at low stage the entire flow at that 

point may be carried through the plant. Water is also diverted from 

Baker River, a tributary, for the operation of the Puget Sound Power & 

Light Co.'s power plant at the mouth of Baker River, and at low stage 

the entire flow of Baker River may be carried through the plant. But at 

both plants water is returned to river, and all water passes through this 

station.

REGULATION. At very low stage flow of upper river is partly controlled by storage 

and release of water at tunnel intake of Seattle's municipal power plant, to 

acc»mmodate plant requirements. Flow of Baker River, a tributary, is 

partly controlled by storage and release of 70,000 acre-feet of water in Baker 

River Reservoir to accommodate requirements of Pug^t Sound Power & 

Light Co.'s Baker River power plant.

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

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

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

integrator. Records excellent except those for October, which are fair.

UPPER COLUMBIA RIVER 71

COLUMBIA RIVER AT KETTLE FALLS, WASH.

LOCATION. In SW. }i sec. 23, T. 36 N., R. 37 E., 150 feet above ferry at Kettle 

Falls, Stevens County, 1% miles above mouth of Colville River, and 4}4 miles 

below mouth of Kettle River.

DRAINAGE AREA. 64,500 square miles. (Areas in United States measured on 

maps issued by United States Geological Survey. Areas in British Columbia 

measured on Department of the Interior railway-belt maps; Department of 

Mines, West Kootenai sheet; and Department of Lands map.)

RECORDS AVAILABLE. April 1, 1916, to September 30, 1926. Monthly discharge 

April, 1913, to March, 1916.

GAGE. Since June 5, 1921, several sets of vertical and inclined staff gages on 

left bank at Kettle Falls ferry, set first at arbitrary datum and later to mean 

sea-level datum; read by employees of Washington Water Power Co. An 

auxiliary low-water gage installed at mean sea-level datum on right or west 

bank January 25 and 26, 1924, was read in conjunction with gages on left 

bank when discharge fell below about 50,000 second-feet. All gage heights 

at the Kettle Falls Ferry have been reduced to mean sea-level datum.

DISCHARGE MEASUREMENTS. Made from cable at gage.

HHANNEL AND CONTROL. Left bank high; right bank is overflowed at extrernely 

high stages. Two channels at extremely low stage. Channel straight for half 

a mile above and 1 mile below gage. Bed composed of small boulders and 

gravel. Control consists of river channel below gage and Rickey Rapids, 

which is about 3 miles downstream from gage; permanent except at extremely 

high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 1,180.0 feet 

May 7 and 8 (discharge, 168,000 second-feet); minimum stage recorded, 

1,164.2 feet January 31 and February 3 and 4 (discharge, 21,000 second feet;. 

1913-1926: Maximum stage, 34.2 feet during night of June 14-15, 1913, as 

determined from well-defined high-water mark referred to United States 

Weather Bureau gage at Marcus (discharge, 468,000 second-feet); minimum 

discharge, 15,800 second-feet, result of current-meter measurements February 

16, 1923, when stage-discharge relation was affected by ice.

The United States Weather Bureau reports a maximum stage of 44.7 feet 

on the Marcus gage during the June flood of 1894 (probably June 7); discharge, 735,000 second-feet, estimated by extending rating curve.

."CE. Stage-discharge relation affected by ice during severe winters; flow estimated from gage-height record, discharge measurements, observer's notest 

and weather records.

DIVERSIONS. Considerable water diverted for irrigation above gage, but amount 

very small in proportion to flow past gage.

REGULATION. None, except the effect of natural storage in Upper and Lower 

Arrow, Kootenai, Flathead, Pend Oreille, Priest, and smaller lakes.

ACCURACY. Stage-discharge relation practically permanent, not affected by ice. 

Rating curve well defined below 500,000 second-feet. Gage read tc hundredths twice daily; morning and afternoon readings made by different 

persons. Daily discharge ascertained by applying mean daily gage height to 

rating table. Records excellent.

The following discharge measurements were made:

January 26, 1926: Gage height, 64.33 feet; discharge, 21,600 second-feet.

May 14, 1926: Gage height, 79.49 feet; discharge, 159,000 second-feet.

UPPER COLUMBIA RIVER

COITJMBIA RIVER AT VERNITA, WASH.

73

LOCATION. In sec. 11, T. 13 N., B. 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 United States measured on 

topographic and other maps issued by the United States Geological Survey. 

Areas in British Columbia measured on Department of the Inter or railwaybelt maps; Department of Mines, West Kootenai sheet; and Department of 

Lands map.)

RECORDS AVAILABLE. Flood heights only at Wenatchee, 1894-1903; continuous 

gage-height record at Wenatchee, April 18, 1904, to December ?1, 1916; at 

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

30, 1926. 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. Gage datum, 388.7 feet above sea level.

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

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

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

control is Coyote Rapids, 6 or 7 miles below gage; low-water control, rifl^e 

about three-fourths mile below gage; apparently permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 17.15 feet at 

6.30 p. m. May 8 (discharge, 197,000 second-feet); minimum stag^, 0.40 foot 

January 31 (discharge, 29,000 second-feet).

1913-1926: 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., 58.0 feet June 7, 1894 (estimated discharge, by extending rating curve, 710,060 second-feet). Th^ Chief of 

Engineers, United States Army, 4 gives a crest elevation of the flood of 1894 

and an elevation of zero on the Weather Bureau gage, from whicl 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.

DIVERSIONS. Some water diverted for irrigation.

REGULATION. None.

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

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

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

excellent.

CLARK FORK BASIN 

CLARE FORE NEAR PLAINS, MONT.

LOCATION. On lot 7, sec. 7, T. 19 N., R. 26 W., at Coopers Ferry, 3 miles above 

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

DRAINAGE AREA. 19,900 square miles.

RECORDS AVAILABLE. October 28, 1910, to September 30, 1926.

GAGE. Stevens continuous recorder, installed November 1, 1924; inspected by 

Mattie Monaghan.

DISCHARGE MEASUREMENTS. Made from cable about 500 feet above gage,

CHANNEL AND CONTROL. The river is deep, and the current is only moderately 

swift, even at flood stages. The banks are high and are not overflowed. The 

channel probably acts as control, as there is no defined control below gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 11.00 feet at 

11 p. m. May 6 (discharge, 47,800 second-feet); minimum stage, 3.97 feet at 

1.45 a. m. January 31 (discharge, 5,910 second-feet).

1910-1926: Maximum stage recorded, 17.9 feet June 5, 1913, and July 2, 

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

during October and November, 1919 (discharge, 4,890 second-feet); lower 

flow may have occurred during the ice period.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Numerous diversions are made for irrigation from the headwaters 

of Clark Fork and tributaries to Flathead River.

REGULATION. Flathead Lake furnishes natural but uncontroHed regulation for 

part of flow.

ACCURACY. Stage-discharge relation permanent during year. Rating curve well 

denned between 5,000 and 100,000 second-feet. Gage heights from recorder 

graph October 1 to November 1 and January 8 to July 20; staff gage read 

once a week November 1 to January 7 and August 1 to September 30. Daily 

discharge ascertained by applying mean daily gage height to rating table 

except for periods as indicated in footnote to daily-discharge table. Records 

for period covered by recorder good; others fair.

The following discharge measurements were made:

January 8, 1926: Gage height, 4.20 feet; discharge, 6,500 se?ond-feet.

July 27, 1926: Gage height, 4.79 feet; discharge, 9,120 second-feet.

falls; installed December 10, 1916; read by Willis Pugh and Earl Phillips.

DISCHARGE MEASUREMENTS. Made from cable at gage. Flow of SuT'van Creek 

added to flow measured at cable.

CHANNEL AND CONTROL. Banks high and not subject to overflow. Sensitive 

and practically permanent control formed by Metaline Falls, the drop over 

which is 20 feet in a distance of 1,200 feet. Elevation of water surface at 

medium low stage, 1,970 feet above sea level.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 19.9 feet May 

11 (discharge, 50,400 second-feet); minimum stage, 2.34 feet August 28 

(discharge, 8,090 second-feet).

1912-1926: Maximum stage recorded, 41.2 feet June 16, 1913 (discharge, 

139,000 second-feet); minimum stage, 2.4 feet December 12, 1919 (discharge, 2,500 second-feet).

Maximum stage at Newport (900 square miles less drainage area) independently determined from three separate high-water marks left by the 

flood of June, 1894, 38.9 feet (discharge, 217,000 second-feet, estimated by 

extending rating curve).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Numerous small diversions from upper tributaries for irrigation.

REGULATION. None.

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

defined above 7,000 second-feet. Gage read to hundredths once daily. No 

diurnal fluctuation. Daily discharge ascertained by applying daily gage 

height to rating table. Records excellent.

second-feet May 4 (gage height, 3.75 feet); minimum stage recorded, 0.03 foot 

at frequently recurring intervals November 18-20 (discharge, 133 secondfeet).

1911-1926: Maximum stage recorded, 6.83 feet at 1.30 p. m. May 20, 1917 

(discharge, 7,290 second-feet); minimum stage recorded, that of November 

18-20, 1926.

ICE. Forms on lake and occasionally in river just below outlet. Stage-discharge 

relation not affected by ice except possibly for short periods when ice running 

out of lake jams on rocks at control.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation practically permanent; affected by logs 

March 24 to September 30 and amount of backwater due to logs uncertain 

over long periods. 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 to rating table mean daily gage 

height determined from recorder graph by inspection and corrected for estimated amounts of backwater. Records excellent October to March; fair 

thereafter.

LOCATION. In sec. 26, T. 49 N., R. 1 E. Boise meridian, in Shoshone County,

\Yz miles above Cataldo and 3 miles below junction of North and South

Forks. 

DRAINAGE AKEA. 1,220 square miles (measured by engineers of Wasl ington

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

best information available). 

RECORDS AVAILABLE. April 25, 1911, to December 31, 1912; July 29, 1920, to

September 30, 1926.
98 SURFACE WATER SUPPLY, 1926, PART XII A

GAGE. Stevens continuous water-stage recorder on left bark 1% miles above 

Cataldo; installed October 11, 1925; inspected by employees of Washington 

Water Power Co. Prior to October 11, 1925, an inclined staff gage on right 

bank opposite present site was used. Approximate elevation of gage datum, 

2,100 feet above sea level.

DISCHARGE MEASUREMENTS. Made from cable about 50 feel above gage or by 

wading 800 feet above.

CHANNEL AND CONTROL. Channel straight for 500 feet above and 1,500 feet 

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

bank is overflowed at gage height about 50 feet. Low-water control is 

boulder and gravel riffle about 1,500 feet below gage; high-water control 

indeterminate, probably long stretch of river channel.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 45.3 feet at 2.30 

p. m. April 19 (discharge, 11,000 second-feet); mininaun stage, 37.30 feet 

August 10 and 11 (discharge, 252 second-feet).

1911-1912, 1920-1926: Maximum stage recorded, 51.3 feet from highwater mark on February 5, 1925 (discharge, 27,600 second-feet); minimum 

stage, 37.0 feet August 27, 1923 (discharge, 215 second-feet). Discharge 

probably lower in December, 1922, while gage was not being read.

COEITE D'ALENE LAKE AT COEUR D'ALEWE, IDAHO

LOCATION. In SW. }{ sec. 13, T. 50 N., R. 4 W., at Johnson Wharf, 800 feet 

southeast of railroad station at Coeur d'Alene, Kootenai County.

DRAINAGE AREA. 3,750 square miles (measured by Washington Wate- Power 

Co. on map of Spokane River Basin compiled from best data avafable).
100 EURFACE WATER SUPPLY, 1926, PART XII A

RECORDS AVAILABLE. February 15, 1905, to September 30, 1926; April 26, 1903, 

to February 14, 1905, at St. Joe Boom Co.'s gage at mouth of St. Joe River.

GAGE. Stevens continuous water-stage recorder at wharf; inspected by employees of Washington Water Power Co. The original gage installed by 

the Geological Survey February 11, 1905, was referred to the Geological 

Survey bench mark in the southeast corner of the Merriam Building, at 

the corner of Sherman and Fourth Streets, Coeur d'Alene, Idaho. This 

bench mark is firmly set in a substantial building which ha? not been moved. 

Accordingly the elevation of the bench mark should be. the same now as 

when it was set. Levels referred to the bench mark, hovever, have sometimes been misinterpreted because various adjustments in level nets have 

resulted in changing its accepted elevation. These accepted elevations are

as follows:

Feet

Original, as published in U. S. Geological Survey Twentyfirst Annual Report, pt. 1, p. 518___-_________ 2, 157. 404 

Second, as published in U. S. Geological Survey Bulletins

487, p. 24, and 567, p. 79--..-------.-------------.-- 2, 157. 909

Third, as determined by adjustment to fit the U. S. Coast

and Geodetic Survey precise-level net__-__------_-_-_-_ 2, 154. 509

Coeur d'Alene Lake stages published in Water-Supply P^.per 272 and subsequent water-supply papers (including this one) refer to the original accepted 

elevations of the bench mark that is, 2,157.404 feet; to obtain mean 

sea-level elevation corresponding to the third accepted elevation of the 

bench mark, add 2,097.105 feet to published stages.

EXTREMES OF STAGE. Maximum stage recorded during year, from water-stage 

recorder, 28.49 feet April 23; minimum stage, 22.17 feet at 1 p. m. November 27.

1903-1926; Maximum stage recorded, 36.00 feet at 6.15 p. m. January 3, 

1918; minimum stage, 19.9 feet October 10-1.2, 1904, September 24-25, 

1905, and October 14 to November 3, 1906.

The maximum stage known to early settlers, 37.6 feet as determined 

from high-water marks, occurred May 31, 1894.

DIVERSIONS. None.

REGULATION. Considerable storage is used by the Washington Water Power 

Co. Flow is regulated by Taintor gates and bear-trap d<Mn at Post Falls.

ACCURACY. Daily mean gage heights have been determined by inspection from 

gage-height graph. Records excellent.

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

RECORDS AVAILABLE. July 13, 1920, to September 30, 1926; April 14, 1911, to

September 30, 1912, at station about 1% miles farther downstream. 

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

landing at Calder; installed December 22, 1920; inspected by Z. D. Turner.

Elevation of gage datum about 2,100 feet above sea level.
SPOKANE RIVER BASIN 107

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

CHANNEL AND CONTROL. Right bank high, not subject to overflow; left bank 

subject to overflow at high stages. Control is shifting gravel riffle 800 feet 

below gage.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 85.97 feet at 

1 p. m. April 19 (discharge, 11,500 second-feet); minimum stage, 7C.07 feet 

from 1 to 5 a. m. November 28 (discharge, 240 second-feet).

1911-12, 1920-1926: Maximum stage recorded, 87.8 feet at 7 a. m. May 

18, 1922 (discharge, 17,600 second-feet). Discharge may have been greater 

on February 2 or 3, 1925, when recorder was not operating and stagedischarge relation was affected by ice. Minimum stage, 78.67 feet at 9.30 

a. m. and from 11 a. m. to 12 m. November 25, 1922 (discharge, 194 secondfeet). Discharge probably less in December, 1922, when stage-d^charge 

; relation was affected by ice.

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

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

DIVERSIONS. 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 four hours.

ACCURACY. Stage-discharge relation changed gradually October 1 to December 

24 and on July 20 and August 31; affected by ice January 1 4, 8-15, and 

20-31. Rating curves fairly well defined. Operation of water-stage 

recorder satisfactory. Daily discharge March 20 to September 30 ascertained by use of discharge integrator; for remainder of year by applying to 

rating table mean daily gage height determined from gage-height g-aph by 

inspection; shifting-control method u&ed October 1 to December 24. 

Records good.

COOPERATION. Gage-height record and some discharge measurements furnished 

by Washington Water Power Co.

LOCATION. In sec. 20, T. 45 N., R. 2 W. Boise meridian, 1,000 feet below Lotus 

station on Elk River branch of Chicago, Milwaukee, St. Paul & Pacific 

Railway and 9 miles above St. Maries and mouth of river, Benewat County.

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

Power Co. on map of Spokane River Basin compiled from best data availRECOEDS AVAILABLE. July 9, 1911, to October 31, 1912, and July 15, 1920, to 

September 30, 1926.

GAGE. Since October 1, 1922, vertical and inclined staff on left bank; read by 

Mrs. Naoma Carter.

DISCHAEGE MEASUREMENTS. Made by wading near gage or from suspension 

footbridge at railway station.

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

straight for 200 feet below gage. Left bank high, not subject to overflow; 

right bank is overflowed at high stages. Control is riffle 150 feet below 

gage; shifting at high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 5.46 feet 

February 8 (discharge, 2,800 second-feet); minimum discharge rot determined but probably occurred during winter, while stage-discharge relation 

was affected by ice.

1911-1912, 1920-1926: Maximum stage recorded, 66.5 feet at 6 a. m. 

March 18, 1921 (discharge, 8,660 second-feet); discharge may have been 

greater sometimes January 31 to February 3, 1925. Minimum discharge 

probably occurred during winter of 1922-23, when stage-discharge relation 

was affected by ice and logs (probably less than 30 second-feet).

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

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

ACCURACY. Stage-discharge relation changed frequently during year, owing to 

shifting of logs OB control; affected by ice November 24-30 and January 1 

to February 5. Rating curves fairly well defined. Gage read to hundredths 

once daily. Daily discharge ascertained by applying daily gage height to 

rating table; shifting-control method used March 3 to April 1, April 9-20, 

April 23-29, and May 16-18. Records fair except for periods represented 

by flat estimates of discharge, which are poor.

COOPERATION. Gage-height record and some discharge measurements furnished

NOTE. Add 2,200 feet to obtain mean sea-level elevations (U. S. Coast and Geodetic Survey dftum). 

SPOKANE VAIIEY FARMS CO.'S CANAI AT POST FAIIS, IDAHO

LOCATION. In NE. J4 sec. 4, T. 50 N., R. 5 W. Boise meridian, on right bank of 

Spokane River 1,200 feet below canal head gates and half a mHe west of Post 

Falls, Kootenai County.

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

to September 30, 1926.

 GAGE. Vertical staff 011 left side of flume; read by K. K. Scott and J. J. Sheaham.

DISCHARGE MEASUREMENTS. Made from crossties 011 top of flume.

CHANNEL AND CONTROL. Flume and canal section below gage; shifts at all 

stages 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.

6 The elevation 2,233.13 feet, previously published, was based upon information obtained by use of a 

ibench mark which had been disturbed and its published elevation, which has been recently rev'sed.
112 SURFACE WATER SUPPLY, 1926, PART XII A

EXTREMES OF DISCHARGE. Maximum discharge, 259 second-feet May 23-26; 

canal dry during nonirrigation season.

1911-1917, 1919-1926: Maximum discharge, 259 second-feet July 23-28, 

1925, and May 23-26, 1926; no water in canal during nonirrigation periods.

ICE. Stage-discharge relation not affected by ice.

ACCURACY. Stage-discharge relation changed gradually May 22 to July 22. 

Rating curves fairly well defined. Gage read to hundredths once daily, 

which is considered adequate for determination of mean daily gage height, 

as two submerged orifices and wasteway above canal head gates are instrumental in causing gage height in canal to remain constant, even though the 

stage of the river is subject to considerable daily fluctuation. Gage at head 

of flume read March 17 to April 21. Daily discharge ascertained by applying gage height to rating table; shifting-control method used May 22 to July 

22. Records for March and April fair; others good.

COOPERATION. Gage-height record furnished. by Spokane Valley Farms Co. 

and some measurements furnished by Washington Water Power Co.

Canal diverts water from right bank of Spokane River in SE. % sec. 3, T. 50 

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

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

feet above intake of Wapatox Canal, and 5 miles northwest of Naches, 

Yakima County.

DRAINAGE AREA. 942 square miles (revised; measured on topographic maps 

and PL I, Water-Supply Paper 369).

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

31, 1912; May 10 to September 30, 1915; April 13, 1916, to September 30, 

1926.

GAGE. Stevens continuous water-stage recorder on left bank; installed December 7, 1916; inspected by R. D. PowelL

DISCHARGE MEASUREMENTS. Made from cable at gage.

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

shifts at extremely high water. One channel except at extremely high 

stages.

EXTREMES OF DISCHARGE. Maximum stage during year, 5.02 feet at 11 p. m. 

April 18 (discharge, 3,190 second-feet); minimum stage, 1.32 feet at 3 a. m. 

September 30 (discharge, 107 second-feet).

1905, 1909-1926: Maximum stage recorded, 8.9 feet at 8 a. m. November 

24, 1909 (discharge, 18,800 second-feet); minimum stage, 1.10 feet from 

7 a. m. September 23 to noon September 24, 1924 (discharge, 57 secondfeet).

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

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

notes, and weather records.

DIVERSIONS. Above all important diversions except Selah Valley and Tieton 

Canals.

REGULATION. Flow partly controlled by storage and release of water at Bumping Lake and at Tieton Reservoir. See records for Bumping Lake and 

Bumping River near Nile, Tieton River and reservoir at Tieton Dam, 

and Tieton Canal near Naches, Wash.
138 SURFACE WATER SUPPLY, 1926, PART XII A

ACCURACY. Stage-discharge relation practically permanent; not affected by 

ice. Possibly slightly affected during periods of low stage by backwater 

from Taintor gates at intake of Wapatox Canal. Rating curve well defined. 

Water-stage recorder inspected daily. Daily discharge ascertained by applying mean daily gage height to rating table. Records good.

COOPERATION. Maintained by the United States Bureau of Reclamation in 

cooperation with Pacific Power & Light Co. Record? for publication 

furnished by Bureau of Reclamation.

NOTE. The run-off without storage and estimated natural discharge shown in the foregoing table represents natural yield as nearly as may be computed from stream-flow records. They do not take in*o 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 theriver gaging.station. Accordinglythe actual natural yield is larger than shown.

BUMPING LAKE NEAR NILE, WASH.

LOCATION. At storage dam in outlet, 12 miles above American River and 19 

miles west of Nile, Yakima County.

DRAINAGE AREA. 68 square miles (measured on topographic maps).

RECORDS AVAILABLE. April 27 to November 22, 1909; November 3, 1910, to 

September 30, 1926.

GAGE. Stages below elevation 3,399 feet obtained by measuring from reference 

point to surface of water since January 6, 1923; vertical staff on gate tower 

used for all stages above elevation 3,399 feet; read by J. H. Nelson. Datum 

of gage is mean sea level.

EXTREMES OP STORAGE. Maximum stage recorded during year, 3,430.29 feet at 

5.10 p. m. May 4 (storage, 39,480 acre-feet); minimum stage, 3,392.95 feet 

September 13-16 (storage, 2,510 acre-feet).

1911-1926: Maximum stage recorded, 3,430.55 feet from 7.05 a. m. June 

21 to 4.50 p. m. June 22, 1925 (storage, 39,840 acre-feet); minimum stage,

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

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

Tieton Canal, 15 miles above mouth, and 16 miles southwest of Naches, 

Yakima County.

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

RECORDS AVAILABLE. April 17 to September 17, 1906 (fragmentary gageheight record); July 5, 1907, to September 30, 1926.

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

intake of Tieton Canal; inspected by Willis Taylor and Jack Bronell.

DISCHARGE MEASUREMENTS. Made from cable about 500 feet below gag^ 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 OF DISCHARGE. Maximum stage recorded during year, 4.86 feet at 

8 a. in. May 14 (discharge, 1,690 second-feet); no flow from 6.30 p. m. 

March 27 to 6.30 a. m. March 28.

1907-1926: Maximum stage recorded, 8.15 feet at 1.20 a. m. December 

13, 1921 (discharge, 6,150 second-feet); no flow from 6.30 p. m. March 27 

to 6.30 a. m. March 28, 1926.

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

DIVERSIONS. Tieton Canal has diverted water above gage since 1910. Diversions through canal added to mean monthly discharge to determine monthly 

flow past gage.

REGULATION. Flow regulated by storage and release of water at Tieton Reservoir, about 7 miles above gage. Monthly discharge corrected for storage 

determined from records of stage at reservoir.

ACCURACY. Stage-discharge relation practically permanent; not affected by 

ice. Rating curve fairly well defined; revised slightly for use after April 1. 

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 good.

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