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, 1927.

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 9.

Measurements of stream flow have been made at about 5f 330 

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

Hawaiian Islands. In July, 1927, 1,750 gaging stations were being 

maintained by the Geological Survey and the cooperating organiza1
2 SURFACE WATER SUPPLY, 1927, PART VIII

tions. Many miscellaneous discharge measurements are 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 "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, and run-off in inches, acre-feet, and millions of 

cubic 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 a 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 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, 1926, and ending September 30, 1927. 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 in ponds,
EXPLANATION OF DATA 3

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 ranoff 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 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

FIGUBE 1. Typical gaging station

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 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 stages, and the accuracy of the records. The
4 SURFACE WATER SUPPLY, 1927, PART VIII

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 oncedaily 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 

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.
PUBLICATIONS O

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 areas of the 

United States are situated above most of the diversions from thosestreams, and the discharge recorded does not show the water supplyavailable for further development, as prior appropriations below th$ 

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, 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 (James River to 

the Mississippi).

III. Ohio River Basin.

IV. St. Lawrence River Basin.

V. Upper Mississippi River and Hudson Bay Basins.

VI. Missouri River Basin.

VII. Lower Mississippi River Basin.

VIII. Western Gulf of Mexico basins.

I.. Colorado River Basin.

X. The Great Basin.

XI. Pacific slope basins in California. 

XII. North Pacific slope basins, in three parts:

A, Pacific slope basins in Washington and upper Columbia River

Basin.

B, Snake River Basin. 

C, Pacific slope basins in Oregon and lower Columbia River Basin.

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 dischage 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 1927. 

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 III are published in Water-Supply Papers 283, 303, 323, 353, 

383, 403, 433,453, 473, and in 503 which contain records for the Ohio 

River Basin for those years.

&4 SURFACE WATER SUPPLY, 1927, PART VIII 

SAN ANTONIO RIVER AT SAN ANTONIO, TEX.

XOCATION. Water-stage recorder at South Alamo Street Bridge in San Antonio, 

Bexar County. Zero of gage is 619.72 feet above mean sea level.

DRAINAGE AREA. 38 square miles.

RECORDS AVAILABLE. January, 1915, to September, 1927.

.EXTREMES. Maximum discharge during year, 845 second-feet June 14 (gage 

height, 5.18 feet); minimum, 7 second-feet April 3 (gage height, 1.03 feet). 

1915-1927: Maximum discharge by slope-area method, 15,300 secondfeet September 10, 1921 (gage height, 20.14 feet, from floodmarks); minimum 

5.1 second-feet July 12, 1925; city of San Antonio turned flow from well into 

river during summer of 1925 to keep river from going dry.

REMARKS. Records fair. Amount of water diverted above gage not known 

but believed to be small. Operation of mill just above gage causes sharp 

diurnal fluctuations. Normal flow of river comes from springs. Changes 

in mean daily stage during low flow are probably caused by pumping from 

deep wells for city water supply and for irrigation, thereby depleting underground reservoir which feeds river through springs.
