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, 1930.

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 caried 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, ard 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 Irind are 

made in connection with the description of each station effected; 

cooperation of the second kind is acknowledged on page 10.

Measurements of stream flow have been made at about 6,07 0 points 

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

Hawaiian Islands. In July, 1930, 2,430 gaging stations we^e being 

maintained by the Geological Survey and the cooperating o^ganiza1

tions. 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 million"' 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 rim-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 irches.

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 stage-discharge relation at the gage.

EXPLANATION OF DATA

The data presented in this report cover the year beginning October 

1, 1929, and ending September 30, 1930. At the bamming 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
EXPLANATION OF DATA d

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

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

and staff gages, cable, and car

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.
4 SURFACE WATER SUPPLY, 1930, PART 12 A

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, 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, information as to diversions that 

decrease the flow at the gage, artificial regulation, maximum and minimum recorded discharge, 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.

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. " 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.
PUBLICATIONS 5

The monthly means for any station may represent with higl accuracy the quantity of water flowing past the gage, but the figures showing discharge per square mile and run-off in inches may be Fubject 

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 f ow at 

the station. The table of daily discharge allows more detailed studies 

of the variation in flow. It should be borne in mind, howeve^*, 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 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, monograph^1 , 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 1. North Atlantic slope basing (St. John River to York River).

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

to the Mississippi).

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

over a series of years. Miscellaneous measurements at man7 points 

other than regular gaging stations have been made each year and are
8 SURFACE WATER SUPPLY, 1930, PART 12 A.

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 

1930. 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, r^hich contain 

records for the Ohio River Basin for those years.

PUGET SOUND BASIN'S 73

SKAGIT RIVER NEAR CONCRETE, WASH.

LOCATION. Water-stage recorder in sec. 16, T. 35 N., R. 8 E., at dalles 2 miles 

below Baker River and 2J4 miles southwest of Concrete. Zero of gage 163 

feet above mean sea level.

DRAINAGE AREA. 2,700 square miles, of which 390 square miles is in Canada.

RECORDS AVAILABLE. September, 1924, to September, 1930.

EXTREMES. Maximum discharge during year, 32,200 second-feet Jun? 7 (gage 

height, 10.01 feet); minimum discharge not determined because of faulty 

gage-height record.

1924-1930: Maximum discharge, 95,500 second-feet Jan. 12, 1928 (gage 

height, 20.2 feet); minimum probably less than 2,160 second-fe?t during 

period Oct. 1-24, 1925, when recorder was not operating and gates in Baker 

River Dam were closed for first time.

High-water marks at gage height 56.6 feet indicate flood of 500,000 secondfeet about 1815. Records of other floods prior to establishment of station are 

given in Water-Supply Paper 612.

REMARKS. Records excellent except those for periods when discharge is represented by braced figures, which were estimated. Water diverted for operation of power plants upstream is returned to river above station. At low 

stages flow partly controlled by storage and release of water at power plants on 

Baker River and on upper Skagit River.

92 SURFACE WATEB SUPPLY, 1930, PART 12 A

KOOTEffAI EIVEE AT BOHITIBS FEBBT, IDAHO

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

at Bonners Ferry. Prior to Nov. 25, 1929, staff gage at same bridge site 

but near opposite bank was used. Gage readings adjusted to elevation 

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

DRAINAGE AREA. 13,000 square miles.

RECORDS AVAILABLE. October, 1927, to September, 1930; May to October, 

1904, at point three-fourths mile downstream. Gage he;?hts collected by 

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

EXTREMES. Maximum discharge during year, 59,200 second-feet June 2; maximum water-surface elevation, 1,764.96 feet June 2; minimum discharge, 

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

Dec. 5.

1927-1930: Maximum discharge, 82,800 second-feet Mey 25,1928; maximum water-surface elevation, 1,772.78 feet May 28, 29, 1928; minimum 

discharge and water-surface elevation occurred in 1930. 

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

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

which are fair. Gage-height records reliable. River partly frozen over 

Jan. 7 to Feb. 18. Because backwater from Kootenai Lake made it 

impossible to rate station by resilts of current-meter measurements, discharge was obtained by combining records collected on Footenai River at 

Katka, Moyie River at Eileen, Cow Creek near Bonners Ferry, and a 

small amount of estimated unmeasured intervening inflow. No allowance 

made for time interval below Katka, which varies from about two to five 

hours, depending upon stage and slope of river. No diversions or artificial 

regulation above station.
