SURFACE WATER SUPPLY OF WESTERN GULF OF MEXICO BASINS, 1952

SCOPE OF WORK

This volume Is one of a series of 18 reports presenting measurements of stage, discharge, and content of streams, lakes, and reservoirs in the United States during the water 

year ending September 30, 1952. Since 1888, when the United States Geological Survey first 

studied streamflow in relation to problems of irrigation, similar measurements have been 

made at more than 12,600 gaging stations in the 48 States and at many others in the Territories of Alaska and Hawaii. On September 30, 1952, the Geological Survey and cooperating 

organizations were maintaining 6,700 gaging stations, including those in Alaska and Hawaii. 

Miscellaneous discharge measurements were made at many other points in the 1952 water year.

COOPERATION

Many State, municipal, and private organizations have cooperated with the Geol.ogical 

Survey in this work by either furnishing or helping to collect data. Organizations that 

supplied data are acknowledged in station descriptions, and organizations that assisted in 

the collection of data through cooperative agreements with the Survey are:

DIVISION OF WORK

The stream gaging was done by the Water Resources Division of the Geological Survey, 

Carl G. Paulsen, chief hydraulic engineer, under the direction of Joseph V. B. Wells, 

chief of the Surface Water Branch. The data for stations in the several States were collected and prepared for publication under the supervision of the district engineers at the 

offices listed below. The records were reviewed and the manuscript prepared for publication under the direction of B. J. Peterson, chief, Annual Reports Section.

records of discharge prior to publication, and other unpublished data concerning the 

gaging station records may usually be obtained from the district office.

DEFINITION OF TERMS AND ABBREVIATIONS

The terms of streamflow and other hydrologic data, as used in this report, are defined 

as follows:

Cubic foot per second (cfs) is the rate of discharge of a stream whose channel is 

1 square foot in cross-sectional area and whose average velocity is 1 foot per second.

Cubic feet per second per square mile (cfsm) is the average number of cubic feet of 

water flowing per second from each square mile of area drained, assuming that the runoff 

is distributed uniformly in time and area.

Runoff in Inches is the depth to which an area would be covered if all the water draining from it in a given period were uniformly distributed on its surface. The term is used 

for comparing runoff with rainfall, which is also usually expressed in inches.

Acre-foot is the quantity of water required to cover an acre to the depth of 1 foot 

and is equivalent to 43,560 cubic feet. The term is commonly used in relation to storage 

for irrigation.

Cfs-day is the volume of water represented by a flow of 1 cubic foot per second for 

24 hours. It is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallons, 

and represents a runoff of 0.0372 inch from 1 square mile.

Stage-discharge re.lation is the relation between gage height and the amount of water 

flowing in a channel, expressed as volume per unit of time.
EXPLANATION OF DATA 3

Control designates a feature downstream from the gage that determines the stage-discharge relation at the gage. This feature may be a natural constriction of the channel, 

a long reach of the channel, or an artificial structure.

Contents is the volume of water in a reservoir. Unless otherwise indicated, volume is 

compute! on the basis of a level pool and does not include banK storage.

The drainage area of a stream at a specified location is that area, measured in a horizontal plane, which is so enclosed by a topographic divide that direct surface runoff from 

precipitation normally would drain by gravity into the river above the specified point. 

Figures of drainage area given herein include all closed basins, or noncontributing areas, 

within the area unless otherwise noted.

DOWNSTREAM ORDER OF LISTING GAGING STATIONS

Beginning with the series of reports for the water year ending September 30, 1951, the 

order of listing gaging-station records was changed. In this report, in a downstream direction along the main stem all stations on a tributary entering above a main-stem station are listed before that station. If a tributary enters between two main-stem stations, 

it is listed between them. A similar order is followed in listing stations on first rank, 

second rank, and other ranks of tributaries. To indicate the rank of any tributary on 

which a gaging station is situated and the stream to which it is immediately tributary, 

each indention in the listing of gaging stations in the table of contents of this report 

represents one rank. This downstream order and system of indention show which gaging stations are on tributaries between any two stations on a main stem and the rank of the tributary on which each gaging station is situated.

The order of"listing used before the publication of the 1951 report listed first all 

stations on the main stem from headwaters toward mouth, then all stations on the uppermost 

tributary to the main stem from the tributary's source to mouth, and then all stations from 

source to mouth of the uppermost tributary to the tributary.

EXPLANATION OF DATA

The base data collected at gaging stations consist of records of stage and measurements 

of discharge. In addition, observations of factors affecting the stage-discharge relation, 

weather records, and other information are used to supplement base data in determining the 

daily flow. The records of stage are obtained either from direct readings on a nonrecording gage or from a water-stage recorder that gives a continuous record of fluctuations. 

Measurements of discharge are made with a current meter by the general methods adopted 

by the Geological Survey on the basis of experience in stream gaging since 1888. These 

methods are described in Water-Supply Paper 888 and are also outlined in standard textbooks 

on the measurement of stream discharge. Typical structures in use at gaging stations are 

shown in figure 1.

Rating tables giving the discharge for any stage are prepared from stage-discharge relation curves defined by discharge measurements. If extensions to the rating curves are 

necessary to define the extremes of discharge, they are made on the basis of indirect 

measurements of peak discharge (such as slope-area or contracted-opening measurements, 

computation of flow over dams or weirs, and by other methods), velocity-area studies, and 

logarithmic plotting. The application of the daily mean gage height to those rating tables

FIGURE 1. GAGING-STATION STRUCTURES.
EXPLANATION OF DATA 5

gives the daily mean discharge, from which the monthly and the yearly mean discharge are 

computed. If the stage-discharge relation is subject to change because of frequent or 

continual change in the physical features that form the control, the daily mean discharge 

is determined by the shifting-control method, in which correction factors based on individual discharge measurements and notes by engineers and observers are used in applying 

the gage heights to the rating tables. If the stage-discharge relation for a station is 

temporarily changed by the presence of aquatic growth or debris on the control, the daily 

mean discharge is computed by what is essentially the shifting-control method.

At some gaging stations the stage-discharge relation is affected: by backwater from 

reservoirs, tributary streams, or other sources. This necessitates the use of the slope 

method in which the slope or fall in a reach of the stream is a factor in determining 

discharge. Information requisite for determining the slope or fall is obtained by means 

of an auxiliary gage set at some distance from the base gage. At some stations the stagedischarge relation is affected by changing stage. If so, the rate of change of stage is 

used as a factor in the determination of discharge.

At most gaging stations in the northern part of the United States and at some in the 

mountainous regions of other parts the stage-discharge relation is affected by ice during 

the winter, and it becomes impossible to compute the discharge in the usual manner. Discharge for periods of ice effect is computed on the basis of the gage-height record and 

occasional winter discharge measurements, consideration being given to the available information on temperature and precipitation, notes by gage observers and engineers, and comparable records of discharge for other stations in the same or nearby basins. If the 

stage-discharge relation is affected by ice, this information is given in a note to the 

table. No mention is made of occasional days of ice effect if the degree of accuracy of 

daily records is not changed.

The data herein presented generally comprise a description of the station, a skeleton 

rating table, and a table showing the daily discharge and monthly and yearly discharge and 

runoff of the stream.

The description of the station gives the location, drainage area, records available, 

type and history of gages, average discharge, extremes of discharge, general remarks, and 

notations of revisions of the previously published record. The location of the gaging 

station and the drainage area are obtained from the most accurate maps available. River 

mileage, given under "Location" for some stations, is that determined and used by the Corps 

of Engineers unless otherwise noted. Under "Gage" are given the type of gage currently in 

use and the datum of the present gage above mean sea level, and a condensed history of the 

types of gages, locations, and datums of previous gages for which discharge records are 

generally equivalent to those at the present site. Under "Average discharge" is given the 

average discharge for the number of years indicated. It is not given for stations having 

fewer than five complete years of record or for stations where changes in water development during the period of record cause the figure to have little significance. Under 

"Extremes" are given the maximum discharge and gage height; the minimum discharge if. 

there Is.little or no regulation; the minimum dally discharge If there is extensive regulation (also the minimum discharge If useful); and the minimum gage height (unless it is 

of no Importance). Unless otherwise qualified, the maximum discharge corresponds to the 

crest-stage obtained by use of a water-stage recorder, a crest-stage Indicator, or a non-
6 SURFACE WATER SUPPLY, 1952, PART 8

recording gage read at the time of the crest. If the maximum gage height did not occur 

at the same time as the maximum discharge, it is given separately. Information pertaining 

to the accuracy of the records and conditions which affect the natural flow at the gaging 

station is given under "Remarks."

Previously published records of some stations have been found to be in error on the 

basis of data or information later obtained. Revisions of such records are usually published along with the current records in one of the annual reports. In order to make it 

easier to find such revised records, a paragraph headed "Revisions (water years)" has been 

added to the description of all stations for which revised records have been published. 

Listed therein are all the reports in which revisions have been published, each followed 

by the water years for which figures are revised in that report. In listing the report 

number, "W" means water-supply paper. In listing the water years only one number is 

given; for instance, 1933 stands for the water year October 1, 1932, to September 30, 

1933. If no daily, monthly, or annual figures of discharge are concerned in the revision, 

that fact is brought out by notations after the year dates as follows: "(M)" means that 

only the instantaneous maximum discharge was revised; "(m)" that only the instantaneous 

minimum was revised; and "(P)" that only peak discharges were revised. If the drainage 

area has been revised, the report in which the revised figure was first published is given. 

It should be noted that for all stations for which cubic feet per second per square mile 

and runoff, in inches, are published, a revision of the drainage area necessitates corresponding revision of all figures based on the drainage area. Revised figures of cubic feet 

per second per square mile and runoff, in inches, resulting from a revision of the drainage 

area only are usually not published in the annual series of reports.

Skeleton rating tables are published for all stations except those at which the daily 

discharge for the greater part of the open-water period was determined by the shiftingcontrol method, the slope method, or other special methods involving an equivalent adjustment to the gage height of more than one-tenth foot.

For stations equipped with water-stage recorders, except those on streams subject to 

sudden or rapid fluctuation, the daily table gives the discharge corresponding to the 

daily mean gage height. For stations subject to such fluctuation the daily mean gage 

height may not indicate the true daily mean discharge, which must be obtained by averaging 

the discharge for parts of the day or by using the discharge integrator, an instrument for 

obtaining the daily mean discharge from a continuous gage-height graph and containing, as 

an essential element, a curve representing the stage-discharge relation at the station. 

For stations equipped with nonrecording gages, the table of daily discharge gives the 

discharge corresponding to once-daily readings of the gage, or to the mean of twice-daily 

readings, or to the mean gage height determined from gage-height graphs based on gage 

readings. For periods of rapidly changing stage, the daily mean discharge is determined 

from gage-height graphs based on gage readings, the frequency of which is stated in the 

station description.

In the table of daily discharge, the values for the maximum day and the minimum day for 

each month are underlined. If the value is repeated, it is underlined only on the first 

day of its occurrence.
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 7

In the monthly summary below the daily table, the line headed "Total" gives the sum of 

the daily values; it is the total cfs-days for the month. The line headed "Mean" gives 

the average flow in cubic feet per second during the month. Runoff for the month may be 

expressed in cubic feet per second per square mile (line headed "Cfsm"), or in inches 

(line headed "In."), or in acre-feet (line headed "Ac-ft"). Values for cubic feet per 

second per square mile and runoff, in inches, are omitted if the drainage area includes 

large noncontributing areas, or if the average annual rainfall over the drainage basin is 

usually less than 20 inches.

In the yearly summary below the monthly summary, the values of maximum are the maximum 

daily discharges, not the momentary discharges when the water was at crest stage. Likewise, the minimums in this summary are the minimum daily discharges.

Peak discharges and the times of their occurrence and corresponding gage heights of 

most stations are listed below the table of daily and monthly discharge. All independent 

peaks above the selected base are given. The base discharge, which is given in parentheses, is selected so that an average of about three peaks a year will be presented. 

Peak discharges are not published for canals, ditches, drains, or for any stream for which 

the peaks are subject to substantial control by man.

Footnotes to the table of daily discharge indicate periods when discharge was computed 

or estimated by unusual or special methods during periods of no gage-height record and ice 

effect, or by other effects that reduce the degree of accuracy of the records. Days on 

which discharge measurements were made are indicated by asterisk and footnote unless they 

were made at frequent regular intervals, in which instance the general frequency of discharge measurements is given under "Remarks" in the station description.

For most gaging stations on lakes and reservoirs the data presented comprise a description of the station and a monthly summary table of stage and contents. For some reservoirs a table showing daily contents or stage is given. A skeleton table of capacity at 

given stages is usually given in the first report in which data for the reservoir are 

published, but it is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of streamflow data depends primarily on (1) the stability of the stagedischarge relation or, if the control is unstable, the frequency of discharge measurements, 

and (2) the accuracy of observations of stage, measurements of discharge, and interpretation of records.

The station description states the degree of accuracy of the records. "Excellent" indicates that, in general, the error in the daily records is believed to be less than 5 percent; "good," less than 10 percent; "fair," less than. 15 percent; and "poor," probably 

more than 15 percent. The records of monthly and yearly mean discharge and runoff are, in 

general, more nearly accurate than the daily records.

Runoff at some stations, as indicated by the monthly mean, may vary widely from natural 

runoff, owing to diversion, consumption, regulation by storage, increase or decrease in 

evaporation due to artificial causes, or to other factors. For such stations, values of 

cubic feet per second per square mile and runoff, in inches, are not published unless 

storage or diversion records are included to indicate the extent of the regulation or diversion, or unless satisfactory adjustments can be made for changes in contents of reser315407 O - 54 - 2
8 SURFACE WATER SUPPLY, 1952, PART 8

voirs or for other changes incident to use and control. Evaporation from a reservoir is 

not included in the adjustments for changes in reservoir contents, unless it is so stated. 

Even at those stations where adjustments are made, large errors in computed runoff may 

occur when relatively large negative adjustments are made or when evaporation is large in 

comparison with the observed discharge.

Many gaging stations on streams in the irrigated areas of the United States are situated above most of the diversions from those streams, and therefore the discharge recorded 

does not actually show the water supply available at the stations for further development, 

because water must first be supplied to existing irrigation systems.

The records at most of the stations discussed In these reports extend over many 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. The streams and points of measurement are listed in the same order as the 

streams and gaging stations in the body of the report. An index of the records obtained 

before 1904 has been published in Water-Supply Paper 119.

Each of the reports on the surface-water supply for the year 1939 (Water-Supply Paper 

878 for Western Gulf of Mexico basins) contains, for the area included in that report, a 

summary of yearly discharge at gaging stations at which 10 or more complete years of 

record had been collected. These summaries were reprinted separately.

Reports also have been published that are compilations of records for various areas, 

usually a single State or drainage basin. These reports contain records previously published (some of which may have been revised), as well as some records not contained in the 

annual series of water-supply papers. The following table lists reports of this type for 

Western Gulf of Mexico basins.

Note. In addition to the gaging stations listed above, the International Boundary & Water Commission collects and publishes records of discharge in floodways in the lower Rio Grande Valley and 

records of diversions from the Rio Grande for irrigation and municipal use.

The Soil Conservation Service of the United States Department of Agriculture has been collecting 

records of runoff from 3 areas of less than 200 acres each near Waco, Tex., beginning in 1938. 

These records are in the files of the Soil Conservation Service.

HYDROLOGIC CONDITIONS

Drought conditions persisted for long periods in the 1952 water year in the Western 

Gulf of Mexico basins except in the extreme western part of the area where drought conditions early in the water year were relieved by flows somewhat above normal for the remainder of the year. The drought was most persistent in central Texas although floods in 

September brought relief to a small part of this area. Floods in the Colorado and Guadalupe River basins in central Texas during September are described in Water-Supply Paper 

1260-A. For two key gaging stations in the area covered by this report, a comparison of 

the monthly and yearly mean discharge during the 1952 water year with the median discharge 

for the 25-year period 1921-45 is shown in figure 3 on the following page.

MERMENTAU RIVER BASIN 

Bayou des Cannes near Eunice, La.

Location.--Lat 30°29'00", long. 92°29i25", in SW^SE^ see. 32, T. 6 S., R. 1 W. , Louisiana 

meridian, on left bank at downstream side of bridge on U. S. Highway 190, 3 miles 

downstream from New Orleans, Texas & Mexico Railway bridge and 4 miles west of Eunice.

Drainage area.--131 sq mi.

Records available.--October 1938 to September 1952.

Gage.--Water-stage recorder. Datum of gage is 14.84 ft above mean sea level, datum of 

1929 (Louisiana Geodetic Survey benchmark ; levels by Corps of Engineers). Prior to 

Jan. 17, 1940, wire-weight gage at same site and datum. Auxiliary water-stage recorder 1.8 miles downstream. Oct. 1, 1943, to Nov. 1, 1950, auxiliary staff gage at 

same site and datum.

Average discharge. 14 years, 259 cfs.

Extremes.--Maximum discharge during year, 2,460 cfs Feb. 4 (gage height, 16.43 ft); minimum, 2.3 cfs Jan. 20, 21; minimum gage height, 1.20 ft Oct. 22, 23, 25, Dec. 1.

1938-52: Maximum discharge, 10,000 cfs July 7, 1946 (gage height, 21.15 ft); no 

flow May 7, 10-18, July 10, 1939, June 23-27, 30, July 1, 1948.

Remarks. Records good except those below 10 cfs and those for periods of no auxiliary 

gage-height record, which are poor. Station is above all known diversions for irrigation.

Revisions.--The peak discharge for June 3, 1950 (11:30 p.m.) has been revised to 2,320 cfs.

Location. Lat 30°30'10", long. 92°54'55", in NW^SE^ sec. 30, T. 6 S., R. 5 W., on left 

bank on downstream side of bridge on U. S. Highway 190, 0.5 mile downstream from Whiskey 

Chitto Creek and 4 miles west of Kinder.

Drainage area. 1,700 sq mi.

Records available. August 1922 to January 1925, October 1938 to September 1952.

Gage. Water-stage recorder. Datum of gage is 12.02 ft above mean sea level, datum of 

1929 (Louisiana Geodetic Survey benchmark). August 1922 to January 1925, water-stage 

recorder at site 400 ft downstream at datum 1.77 ft lower. October 1938 to July 9, 1939, 

wire-weight gage at present site and datum.

Average discharge.--16 years (1922-24, 1938-52), 2,883 cfs.

Extremes. Maximum discharge during year, 30,900 cfs Apr. 28 (gage height, 19.53 ft); minimum, 243 cfs Sept. 10; minimum gage height, 2.45 ft Oct. 31.

1922-25, 1938-52: Maximum discharge, 68,000 cfs Dec. 23, 1923 (gage height, 21.69 

ft, datum then in use, or about 23.5 ft, present datum), from rating curve extended above 

40,000 cfs; maximum gage height, 24.7 ft Aug. 11, 1940 (discharge, 64,400 cfs); minimum 

discharge, 166 cfs Aug. 17, 1951 (gage height, 1.99 ft).

Flood in 1913 reached a stage about 0.3 ft higher than that of Aug. 11, 1940.

Remarks. Records good. Paper mill at Elizabeth pumps about 5 cfs from wells which is 

IsTEer discharged into Mill Creek 36 miles above station. This discharge is continuous 

and fairly constant. Water is diverted during period April to September at points just 

above station and 5 miles above station for the irrigation of about 7,500 acres of rice, 

part of which is below station. The maximum rate of withdrawal is about 100 cfs and this 

diversion results in marked regulation of the low-water flow.

TRINITY RIVER BASIN 63

Clear Pork Trinity River at Port Worth, Tex.

Location.--Lat 32°44', long. 97°31i, near right bank on downstream side of right pier of 

bridge on Vickery Boulevard at Port Worth, Tarrant County, 100 ft upstream from EastWest Expressway bridge, 310 ft downstream from Texas & Pacific Railway bridge, 3 miles 

upstream from mouth, and 5 miles downstream from Marys Creek.

Drainage area.--586 sq mi.

Records available.--March 1924 to September 1952.

Gage. Water-stage recorder and concrete control. Datum of gage is 532.91 ft above mean 

sea level, datum of 1929. Prior to June 23, 1925, staff gage at site 338 ft upstream 

at datum 8.37 ft higher. June 23, 1925, to Dec. 7, 1938, water-stage recorder at site 

88 ft upstream at present datum.

Average discharge.--28 years, 113 cfs; median of yearly mean discharges, 78 cfs.

Extremes.--Maximum discharge during year, 3,190 cfs May 18 (gage height, 6.32 ft); no flow

1924-52: Maximum discharge, 107,000 cfs May 17, 1949 (gage height, 28.20 ft), from 

rating curve extended above 16,000 cfs on basis of contracted-opening determination of 

peak flow; no flow at times.

Maximum stage known since at least 1900, that of May 17, 1949. Flood of Apr. 25, 

1922, reached a stage of 27.5 ft, present datum (discharge, 74,300 cfs, by slope-area 

determination of peak flow, data furnished by city engineer of Port Worth).

Remarks.--Records good except those for periods of no gage-height record, which are fair. 

Flood flow since August 1950 largely regulated by Benbrook Reservoir (capacity, 164,800 

acre-fti revised) located 10 miles upstream. During the year reservoir acted only as 

detention basin and no water was permanently stored. Texas & Pacific Railway Co. diverts small amount of water from pool in which gage is located. Records of chemical 

analyses and water temperatures for water year 1952 are given in Water-Supply Paper 

1252.

Revisions.--W 1148; Drainage area.

64 TRINITY RIVER BASIN

West Fork Trinity River at Fort Worth, Tex.

Location. Lat 32°46' , long. 97°20', on left bank in old pumphouse of Texas Electric

Service Co., 100 ft upstream from Texas Electric Service Go's concrete dam, 150 ft upstream from Paddock Viaduct (Main Street) at Fort Worth, Tarrant County, 0.2 mile downstream from Clear Pork, and at mile 559.

Drainage area.--2,627 sq mi.

Records available.--October 1920 to September 1952. Gage-height records collected in this 

vicinity since 1910 are contained in reports of United States Weather Bureau.

Gage. Water-stage recorder and concrete control. Datum of gage is 519.24 ft above mean 

sea level, datum of 1929 (Texas Reclamation Department benchmark based on Coast and 

Geodetic Survey datum).

Average discharge.--32 years, 457 cfs.

Extremes. Maximum discharge during year, 2,830 cfs May 18 (gage height, 4.52 ft); minimum, 

13 cfs July 23, Aug. 2 (gage height, 1.08 ft).

1920-52: Maximum discharge, 85,000 cfs Apr. 25, 1922 (gage height, 23.95 ft), by 

slope-area method, by city engineer of Fort Worth; maximum gage height, 25.91 ft May 17, 

1949 (discharge, 64,300 cfs); no flow at times.

Maximum stage known since at least 1900, that of May 17, 1949.

Remarks.--Records good except those for periods of no gage-height record, which are fair. 

Flow largely regulated by Bridgeport Reservoir since 1932 (see p. 57), Eagle Mountain 

Reservoir since 1934 (see p. 60), and by Lake Worth (capacity, 33,300 acre-ft). Benbrook Reservoir (capacity, 164,800 acre-ft) acted as detention reservoir during the 

year. During the year the city of Fort Worth diverted 47,200 acre-ft of water from 

Lake Worth for municipal use and returned 33,700 acre-ft of sewage effluent below 

station. Several small diversions above station.

Revisions.--W 1148: Drainage area.

Records available. October 1938 to September 1940 (gage heights, discharge measurements, 

and some records of daily discharge) , October 1940 to September 1952 (high-water records only). Gage-height records collected in this vicinity since 1903 are contained 

in reports of United States Weather Bureau.

Gage. Wire-weight gage read once daily. Datum of gage is 2.22 ft below mean sea level, 

datum of 1929. Prior to June 24, 1942, staff gage at same site and datum.

Extremes. Maximum discharge during year, 24,300 cfs Apr. 25 (gage height, 25.20 ft); minimum not determined (affected by tides); minimum gage height observed, 3.41 ft Sept. 16.

1938-52: Maximum discharge, 114,000 cfs May 12, 1942 (gage height, 29.38 ft); minimum not determined (affected by tides); minimum gage height observed, 2.5 ft Nov. 4, 

1939.

Maximum stage known since at least 1903, that of May 12, 1942. Flood of May 8-11, 

1922, reached a stage of 28.6 ft, present datum, from observation by United States 

Weather Bureau at chain gage on railroad bridge upstream.

Remarks. Records fair. Discharge not computed below gage height 10 ft because tides 

affect the stage-discharge relation. Flow largely regulated by reservoirs above 

Dallas.

Cooperation. Gage-height record furnished by United States Weather Bureau. 

Revisions. W 1148: Drainage area.

Maximum stage known near site of upper gage prior to construction of reservoir, 98.1 

ft in December 1935, from floodmark about 1,100 ft to right of and 1,100 ft downstream 

from upper gage.

Remarks.--Reservoir is formed by rolled-fill earthen-type dam 72,844 ft long. Dam completed Feb. 3, 1946, but was first used for flood control in spring of 1945. Reservoir is operated for flood protection of city of Houston. It is a detention reservoir 

with no provision for permanent storage. Outlet works consist of five concrete conduits, two of which are uncontrolled. The middle conduit is controlled by two vertical-lift steel gates ; the two outer conduits are controlled by single vertical lift 

steel gates. All gates remain closed except during recession of large floods or during 

emergencies. Capacity, 127,900 acre-ft between gage heights 75.0 ft (bottom of conduits) and 101.9 ft (top of design flood pool). No constructed emergency spillways; 

runoff considerably in excess of designed capacity will be discharged around ends of 

dam. Gage heights and contents not published for floods that do not produce a gage 

height of 82.0 ft (top of outlet structure) or higher at dam.

Cooperation. Capacity table and gage-height record at dam furnished by Corps of Engineers.

1948-52: Maximum elevation at dam, 90.5 ft Oct. 8, 9, 1949; maximum at gage on 

South Mayde Creek, 106.8 ft Apr. 22, 1949, Apr. 12, 1952; maximum at gage on Langham 

Creek, 101.9 ft Oct. 8, 1949.

Maximum stage known, 89.9 ft in December 1935 at bridge on U. S. Highway 90, 2,700 

ft downstream from outlet works, from information by Corps of Engineers. This flood, 

from floodmarks, from information by local residents, reached a stage of 109.3 ft, 

0.2 mile downstream, and 0.1 mile to right of gage on South Mayde Creek; and a. stage 

of 104.5 ft, 1,900 ft to left and 700 ft upstream from gage on Langham Creek.

Remarks.--Reservoir is formed by rolled-fill earthen type dam 61,166 ft long. Dam completed In fall of 1948. Reservoir is operated for flood protection of city of Houston. 

It is a detention reservoir with no provision for permanent storage. Outlet works consist of five concrete conduits, two of which are uncontrolled. The middle conduit is 

controlled by two vertical lift gates; the two outer conduits are controlled by single 

vertical lift steel gates. All gates will remain closed except during recession of 

large floods or during emergencies. Capacity, 188,030 acre-ft between gage heights 

73.0 ft (bottom of conduits) and 113.0 ft (top of design flood pool). No constructed 

emergency spillways; runoff considerably in excess of designed capacity will be discharged around ends of dam. Elevations and contents not published for floods that do 

not produce an elevation of 79.0 ft (top of outlet structure) or higher at dam.

Cooperation.--Capacity table and gage-height record at dam furnished by Corps of Engineers.

Elevation and contents, at Indicated time when flood runoff was partially 

stored In reservoir, during period in April 1952

104 OYSTER CREEK BASIM 

Oyster Creek near Angleton, Tex.

Location. Lat 29°09'25", long. 95°28'35", near left bank on upstream side of bridge on 

State Highway 35, 2f miles west of Angleton, Brazoria County, 4.0 miles upstream from 

Missouri Pacific Railroad bridge, 4-| miles downstream from another Missouri Pacific 

Railroad bridge, and about 45 miles upstream from Gulf of Mexico.

Records available. October 1944 to September 1952.

Gage. Water-stage recorder. Datum of gage is 1.31 ft below mean sea level, datum of 1929.

Average discharge. 7 years (1945-52), 142 cfs.

Extremes. Maximum discharge during year, 753 cfs Apr. 24 (gage height, 18.46 ft); minimun, 

U2~~cTs Feb. 7.

1944-52: Maximum discharge, 2,320 cfs Oct. 12, 1949 (gage height, 28.92 ft); minimum, 3.2 cfs Mov. 21, 1948.

Flood of December 1913 reached a stage of about 32 ft, from information by State 

Highway Department; flood of Dec. 5, 1940, reached a stage of 30.7 ft, from levels to 

floodmark on bridge to which gage is attached. At extreme high stages the Brazos River 

overflows into Oyster Creek above this station, and there may be some relation between 

stage of Brazos River at East Columbia and stage at this station.

Remarks. Records fair. Diversions above station for irrigation. A large part of flow is

water released from Harris Reservoir for industrial use below station. Harris Reservoir

is supplied with water diverted from the Brazos River during periods of flood flow.

BRAZOS RIVER BASIN 

Brazos River near Palo Pinto, Tex.

113

Location. Lat 32°51'45", long. 98°18'10", on right bank 35 ft upstream from bridge on 

Palo Pinto-Graford highway, 300 ft downstream from Dark Valley Creek, 6| miles north 

of Palo Pinto, Palo Pinto County, 20 miles downstream from Possum Kingdom Dam, and at 

mile 667.

Drainage area. 22,760 sq mi, approximately,of which 9,240 sq mi is probably noncontributing.

Records available. January 1924 to September 1952. Published as "near Mineral Wells" 

1924-33.

Gage. Water-stage recorder. Datum of gage is 831.23 ft above mean sea level, datum of 

1929. Prior to Nov. 15, 1933, chain gage at site 19 miles downstream at different datum.

Average discharge. 88 years (1924-52), 1,165 cfs.

Extremes. Maximum discharge during year, 2,690 cfs June 26, Aug. 8-(gage height, 4.42 

rt); minimum, 14 cfs Sept. 9 (gage height, 0.02 ft).

1924-52: Maximum discharge, §5,600 cfs June 16, 1930 (gage height, 28.43 ft, site 

and datum then in use); no flow at times.

Maximum stage known was reached by flood of 1876, according to data by Corps of Engineers, and was several feet higher than any subsequent flood. Flood of June 1930 

reached a stage of about 24 ft, present site and datum, from information by local residents.

Remarks. Records good. Flow since 1941 largely regulated by Possum Kingdom Reservoir 

(see preceding page) and several smaller reservoirs above Nugent in Clear Fork basin, 

having a combined capacity of 830,000 acre-ft. Many small diversions above station 

for irrigation, municipal supply, and oil-field operation.

BRAZOS RIVER BASIN 121

Brazos River at Waco, Tex.

Location. Lat 31°33'40", long. 97°07 I 45", on right bank at downstream side of pier of

Washington Avenue Bridge in Waco, McLennan County, 2-| miles downstream from Bosque River 

and at mile 404.

Drainage area. 28,500 sq mi, approximately, of which 9,240 sq mi is probably noncontributing.

Records available. September 1898 to September 1952 (January 1912 to September 1914,

monthly records only, in Water-Supply Paper 850). Gage-height records collected in this 

vicinity since 1900 are contained in reports of United States Weather Bureau.

Gage. Water-stage recorder. Datum of gage is 356.80 ft above mean sea level, datum of 

1929, supplementary adjustment of 1942. Sept. 14, 1898, to Mar. 28, 1918, May 6, 1922, 

to Feb. 12, 1934, staff or chain gages at several sites within about 350 ft of present 

site and at same datum. Mar. 28, 1918, to May 5, 1922, Feb. 13, 1925, to Sept. 29, 

1934, water-stage recorder at site about 300 ft downstream at same datum.

Average discharge. 54 years, 2,593 cfs.

Extremes . Maximum discharge during year, 25,500 cfs May 25 (gage height, 18.13 ft); minimum, 42 cfs Sept. 27, 28.

1898-1952: Maximum discharge, 246,000 cfs Sept. 27, 1936 (gage height, 40.90 ft, 

levee on left bank was overtopped and broken by flood); minimum discharge for periods of 

daily records, 1898-1911, 1914-52, no flow Aug. 20, 21, 1918, and probably for several 

days in August 1923.

Maximum stage, 1854-97, 34.2 ft May 28, 1885. A stage of 39.7 ft was reached Dec. 3, 

1913, when levee on left bank was broken by flood, from information by United States 

Weather Bureau.

Remarks. Records good. Flow largely regulated by Possum Kingdom and Whitney Reservoirs 

on Brazos River (see pp. 112,117), and several small reservoirs in Clear Fork basin, 

and Lake Waco on Bosque River near Waco (capacity, 22,000 acre-ft). A siltation survey 

of Lake Waco by the Soil Conservation Service of the United States Department of Agriculture in December 1947 indicates a 44.07 percent capacity loss from siltation since 

storage began in April 1930. Many small diversions above station for municipal supply, 

irrigation, and oil-field operation do not appreciably affect flow.

Revisions (water years). W 850: (monthly and yearly summaries only, 1899-1905, 1907-10).

River, 5 miles downstream from Texas and New Orleans Railroad bridge, 9 miles southwest of Bryan, Brazos County, and at mile 285.

Drainage area.--38 .430 sq mi, approximately, of which 9,240 sq mi is probably noncontributing.

Records available.--February 1918 to September 1952, in reports of Geological Survey. 

August 1899 to December 1902, in United States Department of Agriculture, Office of 

Experiment Stations, Bulletins Nos. 104, 119, and 133. Prior to September 1925, published as Brazos River near College Station.

Gage. Water-stage recorder. Datum of gage is 192.33 ft above mean sea level, datum of 

T929. Feb. 23, 1918, to Sept. 17, 1925, staff or chain gage at site 7? miles downstream 

at different datum. Sept. 11, 1925, to Oct. 24, 1932, chain gage at site 3,000 ft upstream at same datum.

Average discharge.--33 years (1918-25, 1926-52), 5,587 cfs.

Extremes . Maximum discharge during year, 33,500 cfs May 26 (gage height, 19.24 ft); minimum, 131 cfs Sept. 30.

1925-52: Maximum gage height, 46.1 ft May 20, 1930, present site and datum (discharge not determined); minimum discharge, 87 cfs Aug. 24, 1934.

Maximum stage 1899-1917, about 54.0 ft Dec. 5, 1913, present site and datum.

Remarks. Records good. Flow largely regulated by reservoirs above Waco (see Brazos River 

at Waco). Many small diversions above station for irrigation, municipal supply, and oilfield operation do not appreciably affect flow.

136 BRAZOS RIVER BASIN

Brazos River at Richmond, Tex.

Location.--Lat 29°35', long. 95°45', near right bank on downstream side of pier of bridge 

on U. S. Highway 59 in Richmond, Fort Bend County, 925 ft downstream from Texas & New 

Orleans Railroad bridge and at mile 93.

Drainage area.--44.050 sq mi, approximately, of which 9,240 sq mi is probably noncontributing.

Records available.--January 1903 to June 1906 and October 1922 to September 1952 in reports of Geological Survey. Published as "at Rosenberg" October 1922 to September 1931 

and equivalent except for diversion by Richmond Irrigation Go's canal. June to November 

1901 and June to September 1902 in United States Department of Agriculture, Office of 

Experiment Stations, Bulletins Nos. 119 and 133. Gage-height records collected in this 

vicinity since 1914 are contained in reports of United States Weather Bureau.

Gage. Water-stage recorder and wire-weight gage. Datum of gage is 40.84 ft above mean 

sea level, datum of 1929. June to November 1901, June to September 1902, and January 

1903 to June 1906, various types of nonrecording gages at railroad bridge 925 ft upstream at different daturas. Oct. 1, 1922, to Sept. 30, 1931, chain gage at Rosenberg 

7.6 miles upstream at datum about 4 ft higher.

Average discharge.--32 years (1903-5, 1922-52), 7,564 cfs.

Extremes. Maximum discharge during year, 34,400 cfs May 28 (gage height, 15.75 ft); minimum, 139 cfs Aug. 1.

1903-6, 1931-52: Maximum discharge, 117,000 cfs Nov. 28, 1940 (gage height, 38.40 

ft); minimum, 33 cfs Aug. 23, 24, 1934.

Maximum stage known since at least 1884, 48.2 ft Dec. 10, 1913, present datum, from 

floodmarks on right bank 1,000 ft upstream from gage. From information by Southern 

Pacific Railroad other floods at railroad bridge, present datum, are as follows: May 

1884, stage 43.7 ft; June 13, 1885, stage 44.7 ft; July 1899, stage 45.6 ft; May 2, 

1915, stage 43.3 ft; May 9, 1922, stage 40.9 ft. Flood of June 6, 1929, reached a 

stage of 40.6 ft, present site and datum, from floodmarks (discharge, 120,000 cfs).

Remarks. Records good. Flow largely regulated by reservoirs above Waco. Considerable 

water diverted above station for irrigation and municipal supply. See records of 

American Canal Co.'s canal near Fulshear (see p. 134) and Richmond Irrigation Co.'s 

canal near Richmond (see preceding page). Records of chemical analyses and water 

temperatures for water year 1952 are given in Water-Supply Paper 1252.

Location. Lat 29°26', long. 95°32', on left bank just downstream from South Texas Water 

Co. pumping plant, 3| miles west of Juliff, Fort Bend County, 65 miles downstream from 

Gulf, Colorado and Santa Pe Railway bridge, and at mile 67.

Drainage area.--44.130 sq mi, approximately, of which 9,240 sq mi is probably noncontributing.

Records available . May 1949 to September 1952.

Gage. Two water-stage recorders. Datum of gage is at mean sea level, datum of 1929, 

Houston supplementary adjustment of 1943.

Extremes. Maximum discharge during year, 32,100 cfs May 28 (gage height, 39.02 ft); no 

flow at times due to pumping.

1949-52: Maximum discharge, 48,500 cfs Feb. 15, 1950; maximum gage height, 43.26ft 

Feb. 16, 1950; no flow at times due to pumping.

Maximum stage known since at least 1884, 64.0 ft about Dec. 11, 1913, present datum, 

from floodmark 4 miles to left of gage, from information by local resident. From same 

source and at same site and datum, other floods as follows: About May 10, 1922, stage 

61.0 ft; about June 7, 1929, stage 61.0 ft; about Nov. 29, 1940, stage 61.5 ft. Flood 

of July 1899 was probably exceeded only by flood of 1913.

Remarks. Records good. Flow largely regulated by reservoirs above Waco. Considerable 

water diverted above station for irrigation and municipal supply. See record of American Canal CQ'S canal near Fulshear (p. 134) and Richmond Irrigation Co.'s canal near 

Richmond (p. 135). The Briscoe Irrigation Co. and the South Texas Water o. have permits to divert a maximum of 600 and 400 cfs, respectively, above station for irrigation, 

industrial and municipal supply.

146 COLORADO RIVER BASIN 

Colorado River at Ballinger, Tex.

Location.--Lat 31°43'50", long. 99°56'25", near left bank on downstream side of pier of 

bridge on U. S. Highway 83 in Ballinger, Runnels County, 2,000 ft upstream from Elm 

Creek and at mile 659.

Drainage area. 16.840 sq mi, approximately, of which 11,600 sq mi is probably noncontributing.

Records available. June 1907 to September 1952 (June 1907 to November 1915, monthly

records only in Water-Supply Paper 850). Gage-height records collected in this vicinity from 1903-29 are contained in reports of United States Weather Bureau.

Gage.--Water-stage recorder. Datura of gage is 1,593.74 ft above mean sea level, datum of 

1929. Prior to Nov. 29, 1930, staff, chain, or Mott gages at several sites upstream 

within 1 mile of present site at various daturas.

Average discharge. 45 years, 382 cfs.

Extremes.--Maximum discharge during year, 7,700 cfs June 1 (gage height, 8.92 ft); maximum 

gage height, 9.20 ft Sept. 10 (backwater from Elm Creek); no flow at times.

1907-52: Maximum discharge, 75,400 cfs Sept. 18, 1936 (gage height, 28.6 ft); no 

flow at times.

Maximum stage since at least 1882, about 36 ft in 1884, present site and datum, from 

information by local residents. Flood of Aug. 6, 1906, reached a stage of about 32.0 

ft, present site and datum, from floodmarks (backwater from Elm Creek).

Remarks. Records good except those for period of no gage-height record and those for the 

periods of backwater effect from Elm Creek, which are fair. Small diversions above 

station for irrigation affect low flow. Plow slightly regulated by Lake Colorado City 

(see p. 143), and since July 1952 by Lake J. B. Thomas (capacity, 204,000 acre-ft).

Revisions (water years). W 850: 1916-17. W 1118: Drainage area.

minimum contents since lake filled, 594 acre-ft Oct. 14, 1936 (gage height, 12.6 ft).

Remarks.--Lake is formed by 5,480-foot dam containing a 3,780-foot earthen section, two 

emergency spillways, 300 and 600 ft in length, and a concrete service spillway having 

a bank of fifteen 25-foot taintor gates and one collapsible floodgate. Dam completed 

and storage began Mar. 28, 1930. Total and usable capacity, 14,040 acre-ft between 

gage heights -4.0 ft (bottom of two 36-inch gates) and 32.4 ft (top of collapsible 

floodgate). Figures of contents shown herein represent total contents of lake and are 

unadjusted for siltation. A siltation survey made by the United States Department of 

Agriculture, Soil Conservation Service, indicates a 10 percent capacity loss from 

siltation in 8.2 years (1930-39). Water used for San Angelo municipal supply.

176 COLORADO RIVER BASIN

Barton Springs at Austin, Tex.

Location. Lat 30°16', long. 97°46'. Springs Issue from channel and along banks of Barton 

Creek for a distance of 1,000 ft In Zllker Park at Austin, Travls County. The main 

spring Is near right bank of creek 500 ft upstream from concrete dam forming swimming 

pool, 1,800 ft upstream from bridge at entrance to Zilker Park, and 0.6 mile upstream 

from mouth of Barton Creek.

Records available. November 1894 to September 1952 (discharge measurements only). Summary of all dTscharge measurements prior to October 1937 is contained in Water-Supply 

Paper 850. Daily discharge record of Barton Creek at Austin published for period 

April 1917 to September 1918, closely represents the flow of Barton Springs. *

Extremes. Maximum discharge measured during year, 46.6 cfs Sept. 25; minimum measured, 

11.2 cfs Feb. 11.

1894-1952: Maximum discharge measured, 166 cfs May 10, 1941; minimum measured, that 

of Feb. 11, 1952.

Remarks. Discharge measurements represent total flow of springs including Old Mill Spring 

which is on right bank and about 1,000 ft downstream from main spring. Springs emerge 

from Edwards limestone in Balcones fault zone and respond to rainfall on Edwards 

Plateau. Water used for recreational purposes. The additional head on the springs 

caused by the swimming pool at main spring being full has an appreciable effect on the 

flow of the springs.

(see pp. 170,175), and other smaller reservoirs having a combined capacity of 3,940,000 

acre-ft (revised). About 36,000 acres irrigated above station. During year city of 

Austin diverted an average of about 34 cfs above station for municipal use and returned 

about 16 cfs of treated sewage below station. Records of chemical analyses and water 

temperatures for the water year 1952 are given in Water-Supply Paper 1252.

Colorado River at Wharton, Tex.

Location. Lat 29°18'30", long. 96°06'15", near center of span at downstream side of 

bridge on U. S. Highway 59 In Wharton, Wharton County, 1,000 ft downstream from Texas 

& New Orleans Railroad bridge, 12 miles upstream from Jones Creek, and at mile 67.

Drainage area. 41.150 sq ml, approximately, of which 11,900 sq ml Is probably noncontrlbutlng.

Records available. July 1916 to September 1925, July and August 1938 (flood discharge 

measurements only), October 1938 to September 1952. June to November 1901 and May to 

September 1902, dally records published In United States Department of Agriculture, 

Office of Experiment Stations, Bulletin Nos. 119 and 133. Gage-height records collected in this vicinity since 1935 are contained in reports of United States Weather Bureau.

Gage. Wire-weight gage read twice daily. Datum of gage is 65.42 ft above mean sea level, 

datum of 1929. Prior to Mar. 19, 1919, staff gage and Mar. 19, 1919, to Sept. 30, 

1925, water-stage .recorder at site about 700 ft upstream at different datum.

Average discharge. 19 years (1919-21, 1922-25, 1938-52), 2,980 cfs.

Extremes.--Maximum discharge during year, 17,400 cfs May 29 (gage height, 12.95 ft, from 

graph based on gage readings); minimum, 36 cfs June 8.

1919-25, 1938-52: Maximum discharge observed, 100,000 cfs July 3, 1940 (gage height, 

35.99 ft); no flow Aug. 6, 1925 (result of pumping).

Maximum stage known, 38.9 ft, present datum, Dec. 8, 1913, from information by local 

residents; below Wharton floodwater combined with floodwater of Brazos River. Flood of 

about July 12, 1869, reached about same height. Flood of June 20, 1935, reached a 

stage of 38.2 ft, present datum (discharge, 159,000 cfs, from rating curve extended 

above 145,000 cfs), furnished by United States Weather Bureau. Flood of July 30, 1938, 

reached a stage of 37.4 ft, present datum, observed by Geological Survey engineers (discharge, 145,000 cfs).

Remarks. Records good except those for periods of no gage-height record, which are fair. 

Diversions above station for irrigation and municipal supply. Regulation same as that 

for Colorado River at Austin. Records of chemical analyses and water temperatures for 

the water year 1952 are given in Water-Supply Paper 1252.

Cooperation. Gage-height record collected in cooperation with United States Weather 

Bureau.

Records available. January 1915 to November 1929, February 1939 to September 1952. Estlmated monthly ground-water discharge contained in Water-Supply Paper 773-B and Texas 

Board of Water Engineers Report for Bexar County dated May 1947.

e. Water-stage recorder. Datum of gage is 612.26 ft above mean sea level, datum of 

929. Jan. 26, 1915, to Feb. 27, 1916, staff gage at site 2.2 miles upstream at different datum. Feb. 28, 1916, to Apr. 7, 1920, staff gage at site 1.9 miles upstream 

at different datum. Apr. 8, 1920, to Nov. 16, 1929, water-stage recorder at same site 

and datum.

Average discharge. 27 years (1915-29, 1939-52), 64.6 cfs.

Extremes. Maximum discharge during year, 363 cfs Sept. 18 (gage height, 3.47 ft); minimum, 5.1 cfs Feb. 21; minimum daily, 12 cfs Mar. 8.

1915-29, 1939-52: Maximum discharge, 15,300 cfs Sept. 10, 1921 (gage height, 20.14 

ft, from floodmark), from rating curve extended above 2,000 cfs by slope-area determination of peak flow; no flow at times because of regulation.

Maximum stage known since at least 1819, that of Sept. 10, 1911; flood of July 5, 

1819, equaled or exceeded that of Sept. 10, 1921.

Remarks. Records good. Flood flow regulated by Olmos flood-control reservoir (capacity, 

15,500 acre-ft) about 8| miles upstream. Dam completed in 1926. Normal flovr of river 

formerly came from springs located about 8 miles upstream but now comes largely from 

artesian wells. Springs emerged from Edwards limestone in Balcones fault zone. Diurnal 

fluctuation caused by Industrial pumping from wells (depleting the underground reservoir) above station.

NUECES RIVER BASIN 209

Nueces River at Cotulla, Tex.

Location.--Lat 28°26', long. 99°16', near left bank on downstream side of bridge on

 U. S. Highway 81, at Cotulla, La Salle County, a third of a mile upstream from International-Great Northern Railroad bridge and at mile 236. 

Drainage area.--5,260 sq mi. 

Records available.--July 1915 to June 1918, October 1923 to September 1952. Published

 as "near Cotulla" 1915-18. Gage-height records collected in this vicinity, 1914-17

and since 1922, are contained in reports of United States Weather Bureau. 

Gage.--Wire-weight gage read once daily. Datum of gage is 368.08 ft above mean sea

 level, datum of 1929. July 1, 1915, to June 13, 1918, staff gage at Hargus Dam, 

4 miles upstream at different datum; Oct. 31, 1923, to Aug. 3, 1924, staff gage at 

approximate site of present gage at datum 7.28 ft higher; Aug. 4, 1924, to Nov. 19, 

1934, staff gage at site 5,000 ft downstream at datum 8.42 ft higher; Nov. 20, 1934, 

to July 15, 1938, water-stage recorder at present site and datum.

Average discharge.--39 years (1923-52), 288 cfs.

Extremes.--Maximum discharge during year, 2,130 cfs May 31 (gage height, 12.14 ft); no 

flow at times.

1983-52: Maximum discharge, 82,600 cfs June 18, 1935 (gage height, 32.4 ft, from 

floodmarks), from rating curve extended above 41,000 cfs on basis of slope-area determination of peak flow; no flow at times.

Maximum stage known since 1899, that of June 18, 1935. Flood of June 19, 1899, 

reached a stage of 29.7 ft, from information by local residents.

Remarks.--Records good. Part of flow of Nueces River and its headwater tributaries 

enters Edwards limestone in Balcones fault zone which crosses basin just north of 

Uvalde. At low stages most of headwater flow enters this formation. Low flow 

slightly regulated by small storage reservoirs above station; most of it is diverted 

above station by pumping.

Cooperation. Gage-height record furnished by United States Weather Bureau.

315407 O - 54 - 15
216 NUECES RIVER BASIN

Atascosa River at Whitsett, Tex.

Location. Lat 28°37'20", long. 98°17'05", on right bank 1,600 ft upstream from bridge on 

Whitsett-Calliham county road, 0.9 mile west of Whitsett, Live Oak County, and 4 miles 

downstream from La Parita Creek.

Drainage area. 1.171 sq mi.

Records available. September 1924 to May 1926, May 1932 to September 1952.

Gage. Water-stage recorder and artificial control. Datum of gage is 159.04 ft above mean 

sea level, datum of 1929. Prior to May 8, 1926, chain gage at bridge 1,600 ft downstream at datum 1.38 ft higher.

Average discharge. 21 years (1924-25, 1932-52), 140 cfs.

Extremes.--Maximum discharge during year, 4,000 cfs Sept. 10 (gage height, 22.96 ft); minimum, 0.5 cfs July 12.

1924-26, 193S-52: Maximum discharge, 39,300 cfs July 7, 1942 (gage height, 38.3 ft, 

from floodmark), from rating curve extended above 12,000 cfs on basis of slope-area 

determination at gage height 38.0 ft; no flow at times. 

Maximum stage known, that of July 7, 1942.

Remarks.--Records good except those for period of no gage-height record, which are fair. 

A considerable part of low flow during much of year resulted from flow of several artesian wells near Campbellton, which were drilled by the Lower Nueces River Water Supply 

District and turned into the river to supplement the supply for the city of Corpus 

Christ!.

NUECES RIVER BASIN 217

Nueces River near Three Rivers, Tex.

Location. Lat 28°26'10", long. 98 0 11'10", on left bank 100 ft downstream from San Antonio, 

Uvalde & Gulf (Missouri Pacific) Railroad bridge, half a mile downstream from Frio River, 

2 miles south of Three Rivers, Live Oak County, and at mile 103.

Drainage area. 15,600 sq mi.

Records available. July 1915 to September 1952. United States Weather Bureau has collected 

gage-height records in this vicinity since 1922.

Gage. Water-stage recorder and concrete control. Datum of gage is 101.16 ft above mean 

sea level, datum of 1929. Prior to Apr. 5, 1932, staff gage at railroad bridge 100 ft 

upstream at same datum.

Average discharge. 35 years (1915-18, 1920-52), 794 cfs.

Extremes. Maximum discharge during year, 5,570 cfs May 29 (gage height, 22.51 ft); no flow 

Aug. 12-16.

1915-52: Maximum discharge observed, 85,000 cfs Sept. 18, 1919 (gage height, 46.0 

ft), from rating curve extended above 55,000 cfs; no flow at times. 

Maximum stage known, that of Sept. 18, 1919.

Remarks.--Records good. Part of flow of Nueces and Frio Rivers and their headwater tribu tar les enters Edwards limestone in Balcones fault zone which crosses basin just north 

of Uvalde. At low stages, most of headwater flow enters this formation. Diversions 

above station for irrigation. During, year some water from several artesian wells near 

Campbellton, which were drilled by the Lower Nueces River Water Supply District, was 

turned into the Atascosa River to supplement the supply for the city of Corpus Christ!. 

Records of chemical analyses, water temperatures, and suspended sediment loads for the 

water year 1952 are given in Water-Supply Paper 1252.

Revisions (water years). W 548: 1920, 1921.

218 NUECES RIVER BASIN

Atascosa, Frio, and Nueces Rivers seepage Investigation

During January and April 1951, three series of discharge measurements were made on the 

Atascosa, Frio, and Nueces Rivers, Tex. The purpose was to determine seepage gains or 

losses along the river, and losses in transmission of water from artesian wells near 

Campbellton to the head of Lake Corpus Christ! near Mathis. The channels of the Atascosa, 

Frio, and Nueces Rivers were used to transport the water. The Atascosa River is tributary 

to the Frio River and the Frio River Is tributary to the Nueces River which flows into 

Lake Corpus Christ! .

During the period Jan. 23-26, 1951, prior to drilling of artesian well at Campbellton, 

a seepage investigation of a reconnaissance nature was made from a point near Poteet to 

the head of Lake Corpus Christ!. At this time measurements were made only at those points 

on main stream and tributaries which were easily accessible.

During period Apr. 19 to May 1, 1951, two series of measurements were made from Campbellton to head of Lake Corpus Christi. The first of these was made with one artesian 

well flowing into the river. All inflow and diversions were measured throughout the 

reach. The second was made of river and tributary flow after the artesian well was cut 

off. Additional measurements were made at miles 87.4, 96.4, and 103.8 as It was suspected 

that some well water was still present when the first ones were made (see table).

For complete report on transmission of well water from Campbellton to Lake Corpus 

Christi see Geological Survey Open File Release No. 42, October 1951, Austin, Texas (SW).

220 NUECES RIVER BASIN

Lake Corpus Christ! near Mathis, Tex.

Location. Lat 28°03', long. 97°52', near left end of Mathis Dam on Nueces River, threequarters of a mile upstream from bridge on U. S. Highway 96, 4 miles southwest of Mathis, 

San Patricio County, and at mile 48.

Drainage area. 16,656 sq mi.

Records available . September 1948 to September T.952. The Soil Conservation Service, 

United states Department of Agriculture, in cooperation with Texas Board of Water 

Engineers, has collected fragmentary gage-height records in connection with sedimentation studies since February 1942.

Gage. Wire-weight gage read once daily. Datum of gage is 0.52 ft above mean sea level, 

datum of 1929. Prior to Sept. 10, 1948, a painted gage at same datum on left side of 

first buttress wall of left taintor gate was probably used.

Extremes. Maximum contents observed during year, 44,500 acre-ft May 30, 31 (gage height, 

75.00 ft); minimum observed, 27,850 acre-ft Sept. 11 (gage height, 71.54 ft).

1948-52: Maximum contents observed, 57,000 acre-ft Apr. 30, 1949 (gage height, 

77.05 ft); minimum observed, 14,740 acre-ft May 5, 1951 (gage height, 67.10 ft).

Remarks. Reservoir is formed by a rolled-fill earthen-type dam containing an unregulated 

concrete service spillway 1,048 ft long, and five taintor gates, each 35 ft wide. Dam 

completed and storage began July 24, 1934. Capacity, 39,400 acre-ft at gage height 74 

ft (top of taintor gates and service spillway). Dead storage is negligible. Reservoir 

used for municipal supply for city of Corpus Christ!. Water for city is released 

through sluice gate at gage height 43 ft. Figures given herein represent total storage. 

A siltation survey made by the Soil Conservation Service, United States Department of 

Agriculture, found original capacity of the reservoir to have been 54,000 acre-ft, and 

capacity as of March 1942 as 43,400 acre-ft at spillway crest. A resurvey by that 

agency completed Mar. 31, 1948, found capacity to be 39,400 acre-ft at spillway crest.

Cooperation. Capacity curve furnished by the Soil Conservation Service, United States 

Department of Agriculture. Gage height record furnished by city of Corpus Christ!.

Location.--Lat 28°02' , long. 97°52' , on left bank 6 ft downstream from pier of bridge on 

U. S. Highway 59, 200 ft downstream from Texas & New Orleans Railroad bridge, 0.8 mile 

downstream from Lake Corpus Christi Dam, and 4 miles southwest of Mathis, San Patricio 

County, and at mile 47.

Drainage area. 16,660 sq mi.

Records available. August 1939 to September 1952.

Gage. Water-stage recorder. Datum of gage is 27.53 ft above mean sea level, datum of 

~T929.

Average discharge. 13 years, 899 cfs.

Extremes. Maximum discharge during year, 4,600 cfs May 30 (gage height, 17.45 ft); minimum, 17 cfs Oct. 17.

1939-52: Maximum discharge, 49,400 cfs July 12, 1942 (gage height, 37.38 ft); minimum, 3.7 cfs Aug. 15, 1940; minimum daily, 6.8 cfs Aug. 15, 1940.

Maximum stage known, 39.9 ft in September 1919 (from floodmark) at railroad bridge, 

200 ft upstream, from information by Texas & New Orleans Railroad.

Remarks. Records good. Plow largely regulated by Lake Corpus Christi (see preceding 

page). Diversions above station for irrigation. Water for municipal and industrial 

use at Corpus Christi is released from Lake Corpus Christi above gage and is diverted 

from river at Calallen 36 miles downstream. Records of chemical analyses and water 

temperatures for the water year 1952 are given in Water-Supply Paper 1252.

~T"929. Prior to Apr. 7, 1915, staff or chain gage and Apr. 7, 1915, to Nov. 5, 1935, 

water-stage recorder at railroad and highway bridge in Alamosa half a mile to 2 miles 

downstream at different datums. Nov. 6, 1935, to June 30, 1942, water-stage recorder 

at present site at datum 1.00 ft higher.

Average discharge. 40 years (1912-52), 306 cfs.

Extremes.--Maximum discharge during year, 2,820 cfs June 14 (gage height, ?..63 ft); minimum 

daily, 7.0 cfs Nov. 2.

1912-52: Maximum discharge, 14,000 cfs July 1, 1927; maximum gage height, 10.62 ft 

June 20, 1949; minimum daily discharge, 1.0 cfs May 19, 1950.

Remarks. Records fair except those for periods of ice effect or no gage-height record, 

which are poor. Natural flow of stream affected by transmountain diversions, storage 

reservoirs, ground-water withdrawals and diversions for irrigation, and return flow from 

irrigated areas.

Revisions. W 928: Drainage area.

Rating tables, water year 1951-52, except periods of ice effect (gage height, in

feet, and discharge, in cubic feet per second)

Rio Santa Cruz above Chiraayo in 1930-31) in reports of State engineer.

Gage. Water-stage recorder. Altitude of gage is 6,960 ft (from topographic map). Prior 

to January 1930, staff gage at approximately same site at different datum. Sept. 1, 

1930, to Aug. 12, 1932, at site 1 mile downstream at different datum. Aug. 13, 1932, 

to Oct. 29, 1934, at site 35 ft upstream at datum 1.06 ft higher.

Average discharge.--36 years (1915-29, 1930-52), 33.2 cfs.

Extremes.--Maximum discharge during year. 198 cfs June 10 (gage height, 2.67 ft); maximum 

gage height, 3,00 ft Dec. 22 (ice jam); minimum daily discharge, 4 cfs Nov. 16, Dec. 21.

1931-52: Maximum discharge, 2,610 cfs Sept. 24, 1931 (gage height, 8.20 ft, datum 

then in use), from rating curve extended above 170 cfs by logarithmic plotting; minimum 

daily, 1.1 cfs Dec. 3, 1950.

Remarks. Records good except those for periods of ice effect or no gage-height record, 

which are poor. Discharge measurements generally made twice a month except during 

winter period. Diversions for irrigation of about 1,000 acres above station.

Records available.--February 1895 to December 1905, June 1909 to December 1914, and October 1930 to September 1952 in reports of Geological Survey. February 1895 to December 

1905 and June 1909 to December 1931 in reports of State engineer. In early reports 

this record was published as Rio Grande at Water Tank, "at Rio Grande," and "near 

Buckman."

Gage. Water-stage recorder. Datum of gage is 5,488,48 ft above mean sea level, datum of 

1929. Prior to Mar. 4, 1904, staff gage at site 180 ft upstream at datum 2.02 ft higher. 

Mar. 4 to Oct. 29, 1904, staff gage and Oct. 29, 1904, to Dec. 31, 1905, chain gage at 

same site and datum.

Average discharge.--49 years (1895-1905, 1909-14, 1915-16, 1919-52), 1,687 cfs.

Extremes. Maximum discharge during year, 9,700 cfs May 9 (gage height, 8.75 ft); minimum 

daily, 195 cfs Oct. 1, 2.

1930-52: Maximum discharge, 22,500 cfs May 16, 1941; maximum gage height, 13.70 ft 

May 14, 1941; minimum dally discharge, 128 cfs June 21, 1934.

A daily discharge of 28,800 cfs (gage height, 13.60 ft) was published in reports of 

State engineer for May 23, 1920.

Remarks. Records good. Discharge measurements generally made four times a month. Flow 

partly regulated by El Vado Reservoir (see p. 365) on Rio Chama which contributes 

about 40 percent of total flow. Diversions above station for irrigation of about 

600,000 acres in Colorado and 75,000 acres in New Mexico. Records of chemical analyses, 

water temperatures, and sediment loads for water year 1952 are given in Water-Supply 

Paper 1252.

Location. Lat 35°35'40", long. 107°11'20", in NE£ sec. 30, T. 16 N. , R. 3 W. , on left 

bank a quarter of a mile upstream from mouth, 4| miles northwest of Guadalupe, and 5? 

miles southwest of Cabezon.

Drainage area. 1.390 sq mi, approximately.

Records available. November 1943 to September 1952.

Gage. Water-stage recorder and concrete control. Altitude of gage is 5,895 ft (by barometer) .

Average discharge. 9 years (1943-52), 17.2 cfs.

Extremes. Maximum discharge during year, 3,600 cfs July 7, 28 (gage height, 6.5 ft), from 

rating curve extended above 2,900 cfs on basis of slope-area determinations at gage 

heights 9.6 and 12.8 ft; no flow at times.

1943-52: Maximum discharge, 12,700 cfs July 21, 1944, from rating curve extended 

above 2,500 cfs by logarithmic plotting; maximum gage height, 14.0 ft July 31, 1951; no 

flow at times.

Remarks. Records fair except those below 10 cfs and for periods of no gage-height record, 

which are poor. Discharge measurements generally made three times a month, but more 

frequently during periods of high flow than low-flow periods. Diversions for irrigation 

of about 100 acres above station. Records of sediment loads for the water year 1952 

are given in Water-Supply Paper 1252.

December 1931 in reports of State engineer (prior to 1930 published as "near Las Vegas").

Gage. Water-stage recorder. Altitude of gage is 6,675 ft (from topographic map). Prior 

Uo Mar. 24, 1926, staff gage.

Average discharge. 45 years (1905-11, 1913-52), 20.5 cfs.

Extremes. Maximum discharge during year, 815 cfs Sept. 12 (gage height, 5.54 ft); minimum 

daily, 0.4 cfs at times October to January.

1930-52: Maximum discharge, 6,020 cfs Sept. 3, 1942 (gage height, 7.75 ft), from 

rating curve extended above 1,000 cfs by logarithmic plotting; no flow Oct. 4-9, 1934. 

A very destructive flood, probably the greatest known, occurred Sept. 29, 30, 1904.

Remarks. Records good except those less than 1 cfs and for Aug. 21 to Sept. 7, which are 

fair. Discharge measurements generally made twice a month. Plow partly regulated at 

low flows by small reservoirs owned by Public Service Co. of New Mexico. Diversions 

for irrigation of about 15 acres above station and for Las Vegas city water supply.

Revisions (water years). W 1178: 1942.
