SURFACE WATER SUPPLY OF WESTERN GULF OF MEXICO BASINS, 1936

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 water year ending September 30; 1936. 

The work was begun In 1888 In connection with special studies relating to Irrigation. 

Measurements of stream flow have been made at about 7,200 points in the United States 

and also at many points In Alaska and the Hawaiian Islands. In July 1936, 3,160 gaging 

stations were being maintained by the Geological Survey and the cooperating organizations. Many miscellaneous discharge measurements were made at other points.

In the execution of the work many State and private 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 14.

DEFINITION OF TERMS

The units in which stream-flow data are presented in this report and other terms used 

herein are 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 when the cross-sectional area Is 1 square 

foot and the average velocity Is 1 foot per second.

"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.

"Second-foot-day" is the volume of water represented by a flow of 1 second-foot for 

24 hours.

"Stage-discharge relation" Is an abbreviation for the term "relation of gage height to 

discharge."

"Control" Is a term used to designate the natural section or reach of the channel or 

artificial structure below the gage which determines the stage-discharge relation at the 

gage.

EXPLANATION OF DATA

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

7
8 ACCURACY OF FIELD DATA AND COMPUTED RESULTS

from direct readings on a nonrecordlng 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. Typical gaging stations, equipped with water-stage recorder and measuring 

cable and car, are shown on plate 1.

Rating tables giving the discharge for any stage are prepared from the discharge 

measurements. The application of the dally gage height to these rating tables gives the 

dally 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 usually 

comprise a description of the station, a table showing the dally discharge of the stream, 

and a table of monthly and yearly discharge and run-off. Skeleton rating tables are published except for those stations whose dally discharge for the greater part of the year 

was determined by shifting-control method or by use of slope or other special methods.

The description of the station gives the type of gage, Its latitude and longitude 

determined from the best available maps, and Information In regard to diversions that 

decrease the flow at the gage, artificial regulation from pondage or storage, and the 

accuracy of the records. Under "Average discharge" is given the average discharge for 

the number of years indicated. It Is given only for stations for which there are 10 or 

more complete years of record. Information under "Extremes" gives the maximum discharge 

and gage height; the minimum discharge If there is little or no regulation; the minimum 

daily discharge if there Is extensive regulation, and also the minimum discharge If useful; and the minimum gage height except when It Is of no Importance. Unless otherwise 

qualified, the .maximum discharge corresponds to the crest stage obtained by use of a 

water-stage recorder or a nonrecordlng gage read at the time of the crest. Likewise the 

minimum represents the lowest discharge unless otherwise qualified.

The table of dally discharge gives, for stations equipped with nonrecordlng gages, 

the discharge In second-feet corresponding to once-daily or the mean of twice-daily readIngs of the gage. For stations equipped with water-stage recorders the table gives the 

discharge corresponding to the mean daily gage height except for stations on streams subject to sudden or rapid fluctuation. For stations subject to such fluctuation the mean 

dally gage height may not Indicate the true mean dally discharge, which must be obtained 

by averaging the discharge for intervals of the day or by using the discharge Integrator, 

an Instrument for obtaining the mean dally 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 "Second-foot-days" gives the sum 

for each month of the discharge given In the table of daily 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.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily (1) on the permanency of the stagedischarge 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, In general, the dally records are accurate within

5 percent; "good", within 10 percent; "fair", within 15 percent; and "poor", within 20 

percent 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 depth 

in inches may be subject to gross errors caused by the inclusion of large noncontrlbutlng 

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.

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 station must first be satisfied.

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, and that greater degrees of refinement in computations and records may be warranted with increased data and use of improved equipment.

Note.- The reports which contain records after 1901 are given In the table on page 12.
PUBLICATIONS n

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 1936. The data for any particular station 

will, In general, 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. Special papers 

containing compilation of records previously published and also records not contained In 

the annual series of water-supply papers have been published for some States and drainage 

basins. For example, stream-flow records for the New-Kanawha River Basin In part 3 from 

1895 to 1920 are contained In water-supply Paper 536.

Drainage area.- 2,687 square miles, of which about 152 square miles is probably noncontributing.

Records available.- October 1931 to September 1936.

Extremes.- Maximum discharge during year, 111,000 second-feet Sept. 17 (gage height, 23.4

 feet, 2.4 feet backwater caused by North Concho River) (slope-area determination); no 

flow at times.

1931-36: Maximum discharge, that of Sept. 17, 1936; no flow at times. 

Maximum stage known, 29.7 feet, no backwater affect, Aug. 6, 1906.

Remarks.- Records good except those below 50 second-feet and those above 12,000 second-

 feet, which are poor, and those partly estimated for Oct. 1-6 and Nov. 12-23, which are 

computed on basis of gate openings at Nasworthy dam and are fair. Stage affected by 

backwater from North Concho River Sept. 17, 18, 26, and 27 and discharge computed on 

basis of flow over Nasworthy Dam. Diversions above station for irrigation and municipal 

and power uses. Flow partly regulated, by reservoirs (total capacity, about 11,000 acrefeet) above station, the largest of which is Lake Nasworthy (capacity, 10,500 acrefeet), 6.5 miles upstream.

Discharge, In second-feet, water year October 1935 to September 1936

COLORADO RIVER BASIN 71

North Concho River near Carlsbad, Tex.

Location.- Water-stage recorder (destroyed by flood of Sept. 26), lat. 31°36', long.

 l60u40', Just above State Sanatorium Dam and 2 miles above Carlsbad, Tom Green County. 

Zero of gage is 2,000.8 feet above mean sea level.

Drainage area.- 1,529 square miles, of which about 123 square miles is probably noncontributing.

Records available.- March 1924 to September 1936. 

Average discharge.- 12 years, 71.9 second-feet.

Extremes.- Maximum discharge during year, by slope area method, about 94,600 second-feet

 gept. 26 (gage height, 16.0 feet, from highest floodmarks ever known); no flow June 

24 to July 6.

1924-36: Maximum discharge, that of sept. 26, 1936; no flow at times.

Remarks.- Records good except those above 5,000 second-feet, which are poor. Daily dis-

 charge for Sept. 19-30 determined from a graph drawn on basis of occasional gage 

readings and elevation of flood peaks. Diversions by pumping above station affect 

low-water flow (pump capacity, 40 second-feet). Low-water flow partly regulated by 

small reservoir above gage.

Discharge, in second-feet, water year October 1935 to September 1936

Average discharge.- 21 years, 237 second-feet.

Extremes.- Maximum discharge during year, 158,000 second-feet Sept. 16 (gage height,

 32.2 feet, from floodmarks), from rating curve extended above 40,000 second-feet 

on basis of four slope-area discharge measurements; minimum, 48 second-feet Sept. 

6-8, 12-14.

1915-36: Maximum discharge, by slope-area method, 319,000 second-feet June 14, 

1935 (gage height, 43,3 feet, from floodmarks); minimum, 13 second-feet Aug. 23- 

28, 1918 (gage height, 1.32 feet).

Remarks.- Records good except those above 40,000 second-feet and those for Sept. 15-17,

 computed from fragmentary gage-height record, which are poor. About 2,500 acres 

above and 1,300 acres below station have been declared irrigated. Diversions 

slightly reduce low-water flow. Slight regulation by water-power plant on South 

Llano River.
