AUTHORIZATION AND SCQPB 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, 1929.

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 tin 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 

folio wing items:

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

and for the investigation of underground currents and artesian weMs, 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 arsisting in 

collecting data. Acknowledgments for jjooperation of the first kind 

are made in connection with the description of each statior affected; 

cooperation of the second kind is acknowledged on page 10.

Measurements of stream flow have been made at about 5,830 

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

the Hawaiian Islands. In July, 1929, 2,240 gaging stations were 

being maintained by the Geological Survey and the cooperating 

organizations. Many miscellaneous discharge measurements were
2 SURFACE WATER SUPPLY, 1929, PART XII A

made at other points. In connection with this work cfata 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 tim°, 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 cul^c feet. The 

principal terms used in this series of reports are second-feet, secondfeet per square mile, run-off in inches, and acre-feet. They may be 

defined as follows: t

"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 vould 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 sect'on 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, 1928, and ending September 30, 1929. 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 fora of snow or 

ice, or in ponds, lakes, and swamps, or as underground v^ater and this
EXPLANATION OP DATA 6

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

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

and stafi gages, cable, and car

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

direct readings on a staff gage or 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.
4 SURFACE WATER SUPPLY, 1929, PART XII A

From the discharge measurements rating tables are prepared that 

give the discharge for any stage. 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 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 

regarding location and type of gage, inform? tion as to diversions that 

decrease the flow at the gags, artificial regulation, maximum and 

minimum recorded stages, 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 a t 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.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

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

permanency 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
PUBLICATIONS O

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

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

The monthly means for any station may represent with hi<rh accuracy the quantity of water flowing past the gage, but th«s 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 "rin-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 th^ 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 located above most of the diversions from those 

streams, and the discharge recorded does not show the wate** supply 

available for further development, as prior appropriations telow 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 flow, but 

it has comprised also investigations of such closely allied subjects as 

irrigation, water storage, water powers, underground waM^rs, and 

quality of waters. Most of the results of these investigations have 

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

appeared in the bulletins, professional papers, monographs, and annual 

reports.

The results of stream-flow measurements are now published annually in 12 parts, each part covering an area whose boundaries coincide 

with natural drainage features, as indicated below:

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

II. South Atlantic slope and eastern Gulf of Mexico basins (Jame* River to 

	the Mississippi.)

III. Ohio River Basin.

IV. St. Lawrence River Basin.

V. Hudson Bay and upper Mississippi River Basins.

VI. Missouri River Basin.

VII. Lower Mississippi River Basin.

VIII. Western Gulf of Mexico basins.

The records at most of the stations discussed in these reports extend over a series of years. Miscellaneous measurements f.t many 

points other than regular gaging stations have been made er.ch year
8 SURFACE WATER SUPPLY, 1929, PART XII A

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 Pape*119.

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

1929. 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 for 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.

UPPER COLUMBIA RIVER BASIN 81

COLUMBIA RIVER AT KETTLE FALLS, WASH.

LOCATION. Staff gage in SW. % sec. 23, T. 36 N., R. 37 E., at Kettle Falls, IK 

miles above mouth of Colville River. Gage set to mean sea level datum.

DRAINAGE AREA. 64,500 square miles.

RECORDS AVAILABLE. April, 1913, to September, 1929.

EXTREMES. Maximum discharge during year, 313,000 second-feet Jun^ 16 and 

17 (gage height, 1,188.1 feet); minimum estimated at 17,200 second-feet on 

Jan. 30 and 31.

1913-1929: Maximum discharge, 468,000 second-feet June 14 and 15, 

1913 (gage height, 34.2 feet, from high-water mark referred to United States 

Weather Bureau gage at Marcus); minimum, 15,800 second-feet, result of 

cunent-meter measurement, Feb. 16, 1923.

Maximum stage and discharge for the 1894 flood as previously published 

appear to be unduly large in the light of new information obtained from 

several sources, which indicates that the maximum discharge was about 

700,000 second-feet.

REMARKS. Records excellent except those for period Jan. 22 to Feb- 28, and 

July 3 and Aug. 4, which were estimated. Numerous diversions above gage 

for irrigation, but amount very small in proportion to flow past gage. No 

regulation except natural storage in numerous lakes above gage.

92 SURFACE WATER SUPPLY, 1929, PART XII A

EOOTENAI BITER AT BONNEES FERRY, IDAHO

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

Bonners Ferry. Gage readings adjusted to mean sea level elevation, 

United States Coast and Geodetic Survey datum.

DRAINAGE AREA. 13,000 square miles.

HECORDS AVAILABLE. October, 1927, to September, 1929. Gage heights collected 

by the United States Weather Bureau are available fronr May, 1904, to 

September, 1927. Records were also collected from May to October, 1904, 

by the Geological Survey at a point three-fourths of a mile downstream.

EXTREMES. Maximum discharge during year, 62,700 second-feet May 25; 

maximum water-surface elevation, 1,766.36 feet June 4; minimum discharge, 

2,590 second-feet Jan. 26-31; minimum water-surface elevation, 1,741.89 

feet Mar. 26.

1927-1929: Maximum discharge, 82,800 second-feet May 25, 1928;

maximum water-surface elevation, 1,772.78 feet May 2? and 29, 1928;

minimum discharge and minimum water-surface elevation occurred in 1929.

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

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

REMARKS. Records of elevations are reliable except those for Dec. 4 to Feb. 

13, which may be in error, owing to datum uncertainties. D'^charge records 

are good. River partly frozen over Dec. 4 to Mar. 25. Because backwater 

from Koofcenai Lake made it impossible to rate the station by results of 

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

records collected on Kootenai River ab Katka, Moyie Piver at Efieen, 

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

intervening inflow. No allowance was made for time internal below Katka, 

which varies from about 2 to 5 hours, depending upon the stage and slope 

of river. No diversions or artificial regulation above station. Results of 

several discharge measurements furnished by Dominion Water Power and 

Hydrometric Bureau, Department of the Interior, Canada.
