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 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 the second kind is acknowledged on page 10.
2 SURFACE WATER SUPPLY, 1931, PART 8

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 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 time to time.

DEFINITION OF TERMS

The volume of water flowing in a stream the "rira*ofi:" or "discharge "~-4s 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-oif in inches, and acre-feet. They may be 

defined as follows:

"Second-feet" is an abbreviation for "cubic feet per second." -4 

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 

vejocity 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-oif 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 

tequired to cover an acre to the depth of 1 foot. The term k commonly iised 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 streteh 

of the channel or artificial structure below the gage which determines 

the stage-discharge relation-at the gage. "
SUBl'ACE WATER SUPPLY, 1931, PART 8 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 ifl 

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 

direct readings on a staff or chain gage or from a water-«tag& opecorder 

that gives a eoatamous record of the fluctuations. Measurements of 

discharge are made with a current meter by the general methods 

outlined in standard textbdoks on the measurement of river discharge. 

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

measuring cable and carr is shown in figure 1.

Rating tables giving the dfecjbu-rge for any stage; are |Srepared frdm 

the discharge measurements. The^appHc&tioii of the daily gage 

heights to these rating tables gives the dailf* discharge from which 

the monthly and yearly mean discharge is exanpBtecl.

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

this report comprise & description of the station,, a table showing the 

daily discharge of th$ staeeam, 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 discharges, and the accuracy of the records. The 

maximum discharge given under "Extremes'1 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 o* 

from graphs based on gage readings made once daily or oftener.

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

secoBtd^feet corresponding to the daily gage height, which may foe ,a 

onee daily reading or the mean of twice daily readings of a nonrft* 

cording gage, or the mean daily gage height obtained from, a waterstage recorder graph, s

. At stations on streams subject to sudden or rapid diurnal fluotua-* 

tion, the discharge obtained from the rating table and the mean dailygage height may not be the true mean discharge for the day. If such
4 SURFACE WATER SUPPLY, 1931, PART 8

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.

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

and staff gages, cable, and car

In the table of monthly discharge the column headed "Maximum" 

gives the maximum daily discharge and not the discharge whem the 

water surface was at crest height. Likewise, in the column headed 

 * Mmimum'' 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 %* 

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 hi 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, li&t 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 bejow 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, tmt 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 on the next page.

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 

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 

1931. 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, which contain records for 

the Ohio River Basin for those years.

COLORADO BIVEE BASIN

' SOUTH OONCHO BTOR AT OHRISTOVAI, TEX.

LOCATION. Water-stage recorder at Panhandle & Santa Fe Railway bridge in 

Christoval, Tom Green County. Zero of gage is 2,010.2 feet above mean 

sea level (railroad datum).

DRAINAGE AREA. 434 square miles.

RECORDS AVAILABLE. February, 1930, to September, 1931.

EXTREMES. Maximum stage during period February to September, 1930, 13.7 

feet June 15 (discharge not determined); minimum discharge, 2.8 second-feet 

Sept. 27-28 (gage height, 0.73 foot).

Maximum stage during year ending Sept. 30, 1931, 20.20 feet Oct. 13 (discharge not determined); minimum discharge, 3.0 second-feet Oct. 4 (gage 

height, 0.74 foot).

Flood of Aug. 6, 1906, reached a stage of about 20.0 feet; but discharge 

was probably greater than flood of Oct. 13, 1930, because railroad dump 

did not confine flow in 1906.

REMARKS. Records good. Diversions for irrigation above station.
