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 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 tile second kind is acknowledged on page 10.

Measurements of stream flow have been made at about 6,070 

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

1
& SURFACE WATER SUPPLY, 1930, PART 8

Hawaiian Islands. In July, 1930, 2,430 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 also collected 

in regard to precipitation, evaporation, storage reservoirs, river prb> 

files, 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, secondfeet 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 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 beginning of January 

in most parts of the United States much of the precipitation in the
EXPLANATION OF DATA '3

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

ponds, lakes,, and swamps, or as underground water, and thk 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 j 

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

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 i 

stage, measurements of discharge, and general information used to! 

supplement the gage heights and discharge measurements hi 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 i 

outlined in standard textbooks on the measurement of river discharge, i 

A typical gaging station, equipped with water-stage recorder and \ 

measuring cable and car, is shown in Figure 1. j

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 j 

the monthly and yearly mean discharge is determined.

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" represents the 

crest discharge determined from records of stage by water-stage 

recorders, or in case of nonrecording gages it is determined from flood 

marks or from graphs based on gage readings made once daily ori 

oftener. j

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 nonre- j 

cording gage, or the mean daily gage height obtained from a water-1 

stage recorder graph. I

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 j 

intervals during, the day or by using the discharge integrator, an in-|
4 SUEFACB WATBB SUPPLY, 1930, PABT 8

strument for obtaining mean daily discharge from a continuous gageheight graph and containing as an essential element the rating curve 

of the station. At nonrecording-gage stations the mean daily discharge during flashy floods is determined from gage-height graphs 

based on gage readings made once daily or of tener.

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

and staff gages, cable, and oar

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 5 

ACCURACY OF FIEM) DATA AND COMPUTED BESULTS

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," 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 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 sections 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 

station 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, 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 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
