SUEFACE WATEE SUPPLY OF PACIFIC SLOPE 

BASINS IN WASHINGTON AND UPPEB COLUMBIA BIVEE BASIN, 1931

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, 1931.

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 3C, 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.

2 SURFACE WATER SUPPLY, 1931, PART 12 A

Measurements of stream flow have been made at about 6,270 points 

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

Hawaiian Islands. In July, 1931, 2,660 gaging stations were being 

maintained by the Geological Survey and the cooperating organizations. Many miscellaneous discharge measurements were made at 

other points. In connection with this work, data were 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 hi 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 hi this series of reports ere 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 ^Tere 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, r> the quantity 

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

The following terms not hi 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 stage-discharge relation at the gage.
SURFACE WATER SUPPLY, 1931, PART 12 A 6 

EXPLANATION OF DATA

The data presented in this report cover the year beginning^October 

1, 1930, and ending September 30, 1931. At the beginning of January in most parts of the United States much of the precipitation in 

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

ponds, lakes, and swamps, or as underground water, and this stored

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

and staff gages, cable, and car

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.

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

measurements of discharge and general information used to supple-
4 SURFACE WATER SUPPLY, 1931, PART 12 A

ment the gage heights and discharge measurements in determining the 

daily flow. The records of stage are obtained either from direct readings on a staff or chain gage or from a water-stage recorder that gives 

a continuous record of the fluctuations. Measurements of discharge 

are made with a current meter by the general methods outlined in 

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.

Rating tables giving the discharge for any stage are prepared from 

the discharge measurements. The application of the daily gage 

heights 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 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, in addition to statements 

jegarding location and type of gage, information as to diversions that 

decrease the flow at the gage, artificial regulation, maximum and minimum recorded discharges, and the accuracy of the records. The maximum discharge given under "Extremes" does not represent the crest 

discharge unless a water-stage recorder was in operation or unless a 

nonrecording gage was read at the time of the crest.

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

second-feet corresponding to the daily gage height, which may be a 

once-daily reading or the mean of twice-daily readings of a nonrecording gage or the mean daily gage height obtained from a water-stage 

recorder graph.

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 using the discharge integrator, an instrument 

for obtaining 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. On this average flow are based computations recorded in the remaining columns, which are defined on page 2.
PUBLICATIONS O 

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 records 

are accurate within 5 per cent; "good," within 10 per cent; "fair," 

within 15 per cent; and "poor," within 20 per cent or more.

The monthly means for any station may represent with hizh 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.

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.

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.

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 fow, but 

it has comprised also investigation of such closely allied subjects a& 

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 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 measurement?" at the end 

of each report in the same relative order as the regular gas£ng stations. 

An index of the reports containing records obtained pric* to 1904 has 

been published in Water-Supply Paper 119.

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

1931. The data for any particular station will, as a r'le, be found 

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

(gage height, 40.40 feet); minimum, 23,400 second-feet Jar. 13 (gage height, 

16.62 feet).

90 SURFACE WATER SUPPLY, 1931, PART 12 A

KOOTENAI EIVEK AT BONNERS FERRY, IDAHO

LOCATION. Wire gage in NE. % sec. 27, T. 62 N., R. 1 E., on highway bridge 

at Bonners Ferry. Prior to Jan. 2, 1931, chain gage at same site was used. 

Zero of gage is 1,743.005 feet above mean sea level, United States Coast and 

Geodetic Survey datum.

DKAINAGE AEEA. 13,000 square miles.

RECOBDS AVAILABLE. October, 1927, to September, 1931; May to October, 1904, 

at point three-quarters of a mile downstream. Gage heights collected by 

United States Weather Bureau May, 1904, to September, 1927.

EXTREMES. Maximum discharge during year, 49,400 second-feet May 17; 

maximum water-surface elevation, 1,762.36 feet May 18; minimum discharge, 

2,160 second-feet Jan. 1; minimum water-surface elevation, 1,741.20 feet 

Feb. 14, 15.

1927-1931: Maximum discharge, 82,800 second-feet May 25, 1928; 

maximum water-surface elevation, 1,772.78 feet May 28, 29, 1928; minimum 

discharge, 2,090 second-feet Dec. 10, 1929; minimum water-surface elevation, 1,741.14 feet Dec. 5, 1929.

Maximum elevation known, 1,777.2 feet in June, 1894.

REMARKS. Records of discharge good except for January and February, which 

are fair. Gage-height records reliable. Because backwater from Kootenai 

Lake made it impossible to rate the station by results of current-meter measurements, discharge was obtained by combining records collected on Kootenai River at Katka, Moyie River at Eileen, Cow Creek near Bonners Ferry, 

and a small amount of estimated inflow. No allowance w*s made for time 

interval below Katka, which varies from about two to five hours, depending 

upon the stage and slope of river. Record of daily discharge is closely 

checked by frequent discharge measurements made 1% miles downstream. 

No diversions or artificial regulation above station.

96 SURFACE WATER SUPPLY, 1931, PART 12 A

KOOTENAI RIVER AT PORT HILL, IDAHO

(International gaging station)

LOCATION. Water-stage recorder in SW. % sec. 8, T. 65 N., R. 1 W., 300 feet 

south of international boundary at Port Hill. Zero of gage is 1,700.00 feet 

above mean sea level, United States Coast and Geodeth Survey datum. 

To correct records to agree with datum of Geodetic Survey of Canada, 1928 

adjustment, 0.20 foot should be subtracted.

DRAINAGE AREA. 13,700 square miles.

RECORDS AVAILABLE. May to July, 1904; October, 1927, to September, 1931. 

Gage-height records collected by Dominion Water Power and Hydrometric 

Bureau, Department of the Interior, Canada, from October, 1924, to September, 1927, at same site.

EXTREMES. Maximum mean daily discharge during year, 52,000 second-feet 

May 17; maximum water-surface elevation, 1,754.48 feet May 18; minimum 

daily discharge, 2,240 second-feet Jan. 1; minimum water-surface elevation, 

1,739.65 feet Jan. 22.

1928-1931: Maximum discharge, 83,000 second-feet May 27, 28, 1928; 

maximum water-surface elevation, 1,763.32 feet May 30, 1928; minimum 

discharge, that of Jan. 1, 1931; minimum water-surface e^vation, 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 except those for period Nov. 4 to Dec. 1, which are fair. Discharge 

record includes flow of Boundary Creek and represents entire flow passing 

international boundary. Elevations affected by backwater from Kootenai 

Lake. Daily discharge record based on frequent discharge measurements 

at station referred to record of stage and slope, records of flow of river above 

effect of backwater from Kootenai Lake plus measured inflow from intervening tributaries with allowance for channel storage, and comparison with 

discharge measurements at Bonners Ferry and Copeland1 . This is one of 

the international gaging stations maintained by the United States under 

agreement with Canada.
