SUEFACE WATER SUPPLY OF PACIFIC SLOPE 

BASINS IN WASHINGTON AND UPPEB COLUMBIA EIVEE BASIN, 1928

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, 1928.

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 resov^ces.

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 9.

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

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

Hawaiian Islands. In July, 1928, 1,830 gaging stations were being

l
2 SURFACE WATER SUPPLY, 1928, PART XII-A

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 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, acre-feet, and millions 

of cubic feet. They may be denned as follows:

"Second-feet" is an abbreviation for "cubic feel 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 givei period were 

uniformly distributed on the surface. It is used for comparing 

run-off with rainfall, which is usually expressed in incHs.

An "acre-foot," equivalent to 43,560 cubic feet, is 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 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 stage-discharge relation at the gage.

EXPLANATION OF DATA

The data presented in this report cover the year beginning October 

1, 1927, and ending September 30, 1928. At the beginning of January in most parts of the United States much of the p ^ecipitation in 

the preceding three months is stored in the form of snow or ice, or in
EXPLANATION OF DATA O

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

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

end of September, on the other hand, the only stored water available 

for run-off is possibly a small quantity in the ground; therefore the 

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

from precipitation within that year.

The base data collected at gaging stations consist of records of 

stage, measurements of discharge, and general information used to 

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

FIGURE l. Typical gaging station

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.

From the discharge measurements rating tables are prepared that 

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

heights to these rating tables gives the daily discharge from which 

the monthly and yearly mean discharge is computed.

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

this report comprise a description of the station and a table showing 

the daily discharge of the stream and the monthly and yearly discharge and run-off.

The description of the station gives, in addition to statements 

regarding location and type of gage, 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
4 SUEFACE WATER SUPPLY, 1928, PART XII-A

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 waterstage 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.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily on the permanency of the stage-discharge relation and 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. ExceEent 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 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.

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

at the station. The table of daily discharge allows more detailed
PUBLICATIONS O

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 froir 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 Gee logical 

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 investigation« have 

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

appeared in the bulletins, professional papers, monograph"- 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 m^asurejnents" 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 Pap^r 119.

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

1928. The data for any particular station will, as a rule, be found 

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

area covered by Part III 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.

1916 by J. H. Cave by leveling to two high-water marks.

REMARKS. Records of elevations are reliable. Discharge records rre fair. 

River partly frozen over December 8 to March 5. Owing to backwater 

from Kootenai Lake, making it impossible to rate the station by results 

of current-meter measurements, the discharge was obtained by combining 

the records collected on Kootenai River at Katka, Moyie River at Eileen, 

and Cow Creek near Bonners Ferry, including a small amount of estimated 

unmeasured intervening inflow. No allowance was made for time interval 

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

the stage and slope of river. No diversions or artificial regulation above 

station.

UPPER COLUMBIA RIVER BASIN 95

COEUR D'AIENE LAKE AT COEUR D'ALEKE, IDAHO

LOCATION. Water-stage recorder in SW. >4 sec. 13, T. 50 N,, R. 4 W., at Johnson

Wharf, Coeur d'Alene. 

DRAINAGE ABEA. 3,750 square miles. 

RECORDS AVAILABLE. February, 1905, to September 30, 1928; April, 1903, to

February, 1905, at mouth of St. Joe River.

EXTREMES. Maximum stage during year, 32.05 feet May 14; minimum, 23.29 

feet March 3.

1903-1928: Maximum stage, 36.00 feet January 3, 1918; minimum, 19.9 

feet October 10-12, 1904, September 24, 25, 1905, and October 14 to November 3, 1906.

Maximum stage known, 37.6 feet (from high-water marks) May 31, 1894. 

REMARKS. Records excellent. Elevation of lake surface regulated by Taintor 

gates and bear-trap dam at Post Falls. Original gage installed by Geological 

Survey February 11, 1905, was referred to Geological Survey bench mark in 

southeast corner of Merriam Building, at Sherman and Fourth Streets, 

Coeur d'Alene. The bench mark is firmly set in a substantial building, which 

has not been moved, and therefore the elevation of the bench mark should 

be the same now as when it was set. Levels referred to the bench mark, 

however, have sometimes been misinterpreted because ..various adjustments 

in level nets have resulted in changing its accepted elevation. These 

accepted elevations are as follows:

Original, as published in U. S. Geol. Survey Twenty-first Fee' 

Ann. Kept., pt. 1, p. 518____------_______. 2, 157. 404

Second, as published in U. S. Geol. Survey BuU. 487,

p. 24, and Bull. 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 Paper 272 and 

subsequent water-supply papers (including this one), refer to the original 

accepted elevation of the bench mark (2,157.404 feet); to obtain mean sealevel elevation corresponding to the original elevation of the bench mark, 

add 2,100 feet to published stages. Gage-height record furnished by Washington Water Power Co.

Daily gage height, in feet, 1927-28
