SURFACE WATER SUPPLY OF PACIFIC SLOPE 

BASINS IN WASHINGTON AND UPPER COLUMBIA RIVER BASIN, 1934

AUTHORIZATION AND SCOPE OF WORK

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

measurements of flow made on streams in the United States during 

the year ending September 30, 1934.

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 carried 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 data or by assisting in collecting 

data. Acknowledgments for cooperation of the first kind are made 

in connection with the description of each station affected; cooperation 

of the second kind is acknowledged on page 10.

Measurements of stream flow have been made at about 6,900 points 

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

Hawaiian Islands. In July 1934, 2,940 gaging stations were being 

maintained by the Geological Survey and the cooperating organiza1

tions. 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.

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 a certain class of work. 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 natural section or stretch 

of the channel or artificial structure below the gage, which determines 

the state-discharge relation at the gage.

EXPLANATION OF DATA

The data presented in this report cover the year beginning October 

1, 1933, and ending September 30, 1934. At the beginning of January in most parts of the United States much of the precipitation in 

the preceding 3 months is stored in the form of snow or ice, or in 

ponds, lakes, and swamps, or as underground water, and this stored
EXPLANATION OF DATA 6

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 the year beginning October 1 is practically all derived 

from precipitation within that year.

FIGURE 1. Typical river-measurement station, showing concrete well and house for water-stage recorder

and staff gages, cable, and car.

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 nonrecording gage, or from a water-stage recorder that 

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

in 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.
4 SURFACE WATER SUPPLY, 1934, PART 12-A

Rating tables giving the discharge for any stage are prepared from 

the discharge measurements. The application of the daily gage 

height to these rating tables gives the daily discharge from which 

the monthly and yearly mean discharge is computed.

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

this report usually comprise a description of the station, a table 

showing the daily discharge of the stream, and a table of monthly 

and yearly discharge and run-off.

The description of the station gives information in regard to the 

location and type of gage, diversions that decrease the flow at the 

gage, artificial regulation from pondage or storage, and the accuracy 

of the records. Under "Average discharge" is given the average 

discharge for the number of years indicated. It is given only for 

stations for which there are 10 or more complete years of record. 

Information under "Extremes" gives the maximum discharge and 

gage height; the minimum discharge, if there is little or no regulation; the minimum daily discharge, if there is extensive regulation, 

and also the minimum discharge, if useful; and also the minimum 

gage height except when it is of no importance. Unless otherwise 

qualified, the maximum discharge corresponds to the crest stage 

obtained by use of a water-stage recorder or a nonrecording gage read 

at the time of the crest. Likewise the minimum represents the lowest discharge unless otherwise qualified.

The table of daily discharge gives, for stations equipped with nonrecording gages, the discharge in second-feet corresponding to oncedaily or the mean of twice-daily readings of the gage. For stations 

equipped with water-stage recorders the table gives the discharge 

corresponding to the mean daily gage height except for stations on 

streams subject to sudden or rapid fluctuation. For stations subject 

to such fluctuation the mean daily gage height may not indicate the 

true mean daily discharge, which must be obtained by averaging 

the discharge for intervals of the day or by using the discharge 

integrator, an instrument for obtaining the mean daily discharge 

from a continuous gage-height graph and containing as an essential 

element the rating curve of the station.

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

gives the maximum daily discharge, and not the discharge when the 

water surface was at crest height. Likewise, in the column headed 

"Minimum" the quantity given is the minimum daily discharge. 

The column headed "Mean" is the average flow in cubic feet per 

second during the month.
SURFACE WATER SUPPLY, 1934, PART 12-A 5 

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.

The station description gives a statement in regard to the general 

accuracy of the records. "Excellent" indicates that, in general, the 

daily records are accurate within 5 percent; "good", within 10 percent; "fair", within 15 percent; and "poor", within 20 percent or 

more.

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 run-off 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.

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 first be satisfied.

The table of monthly discharge gives a general idea of the flow at 

the station. The table of daily discharge allows 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, and that greater degrees of 

refinement in computations and records may be warranted with 

increased data and use of improved equipment.

In order to permit greater refinement in analysis and comparison 

of records for adjacent stations, the following changes have been 

made in the computation procedure: (a) Mean monthly discharge 

above 1,000 second-feet and monthly run-off above 10,000 acre-feet 

are expressed to four significant figures instead of three significant 

figures as formerly; (b) monthly run-off in acre-feet is computed from 

the total second-foot-days for the month and not from the mean discharge for the month; (c) drainage areas above 1,000 square miles, if 

measured on topographic maps, or if otherwise warranted, are 

expressed to four significant figures instead of three as formerly. 

Some of the records in the series of reports for 1934 have been computed in accordance with the modified procedure.
6 SURFACE WATER SUPPLY, 1934, PART 12-A

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 ar6 now published annually in 12 parts, each part covering an area whose boundaries coincide 

with natural drainage features as indicated below:

Part 1. North Atlantic slope basins (St. John River to York River).

2. South Atlantic slope and eastern Gulf of Mexico basins (James River 

to Mississippi River).

3. Ohio River Basin.

4. St. Lawrence River Basin.

5. Hudson Bay and upper Mississippi River Basins.

6. Missouri River Basin.

7. Lower Mississippi River Basin.

8. Western Gulf of Mexico basins.

9. Colorado River Basin.

10. The Great Basin.

The records at most of the .stations discussed in these reports 

extend over a series of years. Miscellaneous measurements at many 

points other than regular gaging stations have been made each year 

and are published under "Miscellaneous discharge measurements" at 

the end of each report in the same relative order as the regular gaging 

stations. 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 

1934. The data for any particular station will, as a rule, be found 

in the reports covering the years during which the station was maintained. For example, data from 1910 to 1920 for any station in the 

area covered by part 3 are published in Water-Supply Papers 283, 

303, 323, 353, 383, 403, 433, 453, 473, and 503, which contain records 

for the Ohio River Basin for those years.

COOPERATION

The work was done under cooperative agreements with the several 

States as follows: In Idaho with the Department of Reclamation, 

R. W. Faris, commissioner; in Montana with the office of the State 

engineer, J. S. James; in Washington with the Department of Conservation and Development, E. F. Banker, director, and C. J. 

Bartholet, supervisor of hydraulics, Division of Water Resources; with 

the cities of Aberdeen, Everett, Seattle, and Tacoma; with King and 

Pierce Counties, through the Intercounty River Improvement Commission; with Skagit and Whatcom Counties; and with Wenatchee 

Reclamation District.

Acknowledgment of financial assistance in collecting records published herein is due also to the United States Department of State, 

United States Bureau of Reclamation, United States Forest Service, 

and United States Indian Service.

Full cooperation exists between this organization and the Dominion 

Water Power and Hydrometric Bureau, Department of the Interior, 

Canada. On waters adjacent to the international boundary certain 

stations are maintained jointly by the United States and Canada 

under the terms of the Boundary Waters Treaty of 1909, and 

others are maintained under a subsequent agreement between the 

two governments. The records from all these stations are obtained 

in such a manner as to be equally acceptable and available in either 

country. These stations are herein designated "international gaging 

stations."

Assistance in collecting the records was also rendered by the following municipalities, corporations, and individuals: In Idaho by the 

Washington Water Power Co.; in Montana by the Rocky Mountain 

Power Co.; in Washington by the Chelan Copper Mining Co., Chelan 

Electric Co., Columbia Basin Commission, Grays Harbor Railway & 

Light Co., Hugh L. Cooper Co., The Northwestern Power & Light 

Co., Washington Electric Co., West Coast Power Co., The Puget 

Sound Power & Light Co., The Washington Water Power Co., and 

the Western Washington Electric Light & Power Co.

DIVISION OF WORK

The data for stations in the several States were collected and prepared for publication under supervision of district engineers as follows: 

In Idaho (except Clark Fork at Priest River) and fqr Clark Fork near 

Heron, Mont., Flathead River at Trail Creek, Mont., and Kootenai 

River stations at Newgate, British Columbia, and Rexford, Mont., 

T. R. Newell; in Montana, except those noted above, W. A. Lamb; 

in Washington and for Clark Fork at Priest River, Idaho, G. L. 

Parker.

camp, 3£ miles upstream rrom Bonners Ferry, and 4 miles downstream rrom Moyie River. 

Prior to Aug. 23, 1934, staff gage with same datum and same location was used. 

Zero of gage is 1,754.08 reet above mean sea level, U. S. Coast and Geodetic Survey 

datum.

Records available.- October 1927 to September 1934. From April 1925 to September 1927 

records were collected by Dominion Water Power and Hydrometric Bureau, Department 

of Interior, Canada.

Extremes.- Maximum water-surface elevation recorded during year, 1,774.68 reet Apr. 28; 

maximum probably occurred Apr, 29, when gage was not read; minimum, 1,757.44 reet 

Sept. 30.

1927-34: Maximum recorded waters-surface elevation, 1,776.58 feet June 18, 1933; 

minimum, 1,756.20 feet Dec, 3, 1931 (also estimated for Jan. 1, 1931).

Remarks.- Records good October to Aug. 22; excellent thereafter. Gage read once daily 

October to Aug. 22 and may not take account of diurnal fluctuations. No record on 

days ror which no elevation is shown. Elevations afrected by backwater from Kootenai 

Lake.

Hote.- Add 1,700.00 feet to obtain elevations above mean sea level, U. S, Coast and Geodetic 

Survey datum.
KOOTENAI RIVER BASIN 75

Kootenal River at Bonners Ferry, Idaho

Location.- Wire gage in NEi sec. 27. T. 62 N., R. IE., on highway bridge at Bonners 

Ferry. Zero of gage Is 1,743.005 feet above mean sea level, U. s. Coast and Geo- detic Survey datum.

Drainage area.- 13,000 square miles.

Records available.- October 1927 to September 1934. May to October 1904 at point threequarters or a mile downstream. Gage-height records collected bv U. S. Weather 

Bureau May 1904 to September 1927.

Extremes.- Maximum discharge during year, 89,400 second-feet Apr. 29: maximum watersurrace elevation, 1,773.04 feet Apr. 29; minimum dally discharge, 4,620 secondfeet Sept. 30; minimum water-surface elevation, 1,743.92 feet Sept. SO

1927-34: Maximum discharge, 99,800 second-feet June 18, 1933; maximum watersurface elevation, 1,774.96 feet June 19, 1933; minimum discharge, 1,930 secondfeet Feb. 10, 1933; minimum water-surface elevation. 1,741.14 feet Dec. 5 1929

Maximum elevation known, 1,777.2 feet In June 1694.

.Remarks.- Records of discharge good. Gage-height records excellent. Discharge records 

comparable to those heretofore published were obtained by application of discharge 

measurements made li miles downstream to gage heights at Boom camp or by slope 

method computation when affected by backwater, using slope between station and waterstage recorder 8,700 feet upstream. No artificial regulation or diversions above station.

KOOTENAI RIVER BASIN 8

Kootenai River at Port Hill, Idaho 

(International gaging station)

Location.- Water-stage recorder in SWi sec. 8, T. 65 N., R. 1 W., 300 feet south of

 TnTernatlonal boundary at Port Hill. Zero of gage is 1,700.00 feet above mean 

sea level, U. S. Coast and Geodetic Survey datum, and 1,699.80 feet above mean 

sea level, datum of Geodetic Survey of Canada, adjustment of 1928.

Drainage area.- 13,700 square miles.

Records available.- May to July 1904, October 1927 to September 1934. Gage-height

 records collected by Dominion Water Power and Hydrometrlc Bureau, Department of 

Interior, Canada, from October 1924 to September 1927 at same site.

Extremes.- Maximum mean daily discharge during year, 89,300 second-feet Apr. 29;

maximum water-surface elevation, 1,761.97 feet June 1; minimum mean daily discharge, 4,840 second-feet Sept. 30; minimum water-surface elevation, 1,741.92 

feet Sept. 30.

1928-34: Maximum discharge, 93,200 second-feet June 19, 1933; maximum watersurface elevation, 1,763.92 feet June 20, 1933; minimum discharge, 2,060 secondfeet Feb. 10, 1933; minimum water-surface elevation, 1,739.32 feet Jan. 28, 1930. 

Maximum elevation known, 1,772.7 feet June 1894.

Remarks.- Discharge records good. Records of water-surface elevations excellent. Discharge record includes flow of Boundary Creek and represents entire flow passing 

international boundary. Elevations affected by backwater from Kootenai Lake. 

Daily discharge record obtained by adding tributary inflow to discharge's near 

Copeland. Breach In the dike of the Reclamation Farm remained open during year, 

allowing part of the river flow and part of normal tributary Inflow to pass the 

international boundary at that point during April, May, June, and July. List of 

discharge measurements of flow In the regular channel and reversed flow entering 

mouth of Boundary Creek are shown for the 4 month period. This station is one 

of the international gaging stations maintained by the United States under agreement with Canada.
