SURFACE WATER SUPPLY OF WESTERN GULF OF MEXICO BASINS, 1942

SCOPE OF WORK

This volume is one of a series of 14 reports presenting results of measurements of 

stage and flow nade on streans, lakes, and reservoirs in the United States during the 

water year ending September 30, 1942. The work was begun in 1888 in connection with 

special studies relating to irrigation. Measurements of the flow of streams and of the 

stage and contents of lakes and reservoirs have been made at about 9,400 gaging stations 

in the United States and also at many gaging stations in Alaska and Hawaii. In July 1942, 

4,970 gaging stations were being maintained by the Geological Survey and cooperating organizations. Miscellaneous discharge measurements were made at many other points.

In the execution of the work nany State and private organizations have cooperated, 

either by furnishing data or by assisting in collecting data. Cooperation of the first 

kind is acknowledged in connection with the description of each station affected; cooperation of the second kind is acknowledged on page 12.

DEFINITION OF TERMS

The units in which stream-flow data are presented in this report and other terns 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 a stream whose channel is 1 square foot in cross-sectional area and 

whose average velocity is 1 foot per second.

"Second-feet per square nile" is the average number of cubic feet of water flowing per 

second from each square mile of area drained, on the assumption that the runoff is distributed uniformly both as regards time and area.

"Runoff in inches" is tine 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. It is used 

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

An "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 connection with 

storage for irrigation.

"Second-foot-day" is the volume of water represented by a flow of 1 second-foot 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 relation" is an abbreviation for the term "relation between gage 

height and discharge."

"Control" is a term used to designate a feature downstream from the gage that determines 

the stage-discharge relation at the gage. This feature may be a natural section, a reach 

of the channel, or an artificial structure.

2 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 records of stage and discharge 

measurements in determining the dally flow. The records of stajje are obtained either from 

direct readings on a nonrecording gage or fron 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 structures in use at gaging stations are shown on plate 1.

Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application of the daily mean gage height to these rating tables 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 dally 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. At times the stage-discharge relation for a station nay be 

temporarily changed by the presence of aquatic growth or debris on the control. For such 

times the daily mean discharge is computed by what is essentially the "shifting-control" 

method, described above.

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

reservoirs, tributary streams, or other sources, which necessitates the use of the "slope 

^method," in which the slope or fall in a reach of the stream is a factor in the determination of 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 stage-discharge relation is affected by changing stage, and for them 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, which makes it 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 stations in the same or nearby basins. The days 

included in the periods of ice effect and the days during the winter period on which discharge measurements were made are indicated in the table by symbols referring to footnotes 

or are given in a general note following the table.

For most of the gaging stations on streams in the area covered by this report the data 

presented comprise a description of the station, a table showing the daily discharge of 

the stream, and a table of monthly and yearly discharge and runoff. Skeleton rating 

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

greater part of the year was determined by the shifting-control method, the slope method, 

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

EXPLANATION OF DATA 3

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. Under "Extremes" are given the maximum discharge and gage 

height; the r.ilnimum discharge if there is little or no regulation; the ninimum daily discharge if there is extensive regulation lalso 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 or a nonrecording gage read at the time of tne crest. Likewise the minimum dis- - 

charge represents the lowest stage, unless otherwise qualified. Selected peak discharges 

with the times of their occurrence are given below the table of monthly discharge for some 

stations. This supplementary information is generally omitted for stations having drainage areas of less than 10 square miles or more than 10,000 square miles or if the peak 

discharges usually exceed the corresponding mean discharges for the day by less than 10 

percent.

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

discharge in second-feet corresponding to once-daily readings of the gage or the mean of 

twice-daily readings. For flashy floods the daily mean discharge is determined from 

gage-height graphs based on gage readings nade once or twice daily or oftener, as stated 

in the station description. For stations equipped with water-stage recorders, except those 

on streams subject to sudden or rapid fluctuation, the table gives the discharge corresponding to the dally 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.

In the table of monthly discharge the column headed "Second-foot-days" gives the sum 

for each month of the figures given in the table of daily discharge. The column headed 

"Maximum" gives the maximum daily discharge and not the momentary discharge when the 

water surface was at crest stage. Likewise, in the column headed "Minimum" the quantity 

given is the minimum daily discharge. The column headed "Mean" gives the average flow 

In cubic feet per second during the month.

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 is given. A skeleton table of capacity at given stages Is 

usually given in the first report in which data for a station are published but Is omitted 

from succeeding reports.

TIKE BASIS

At 2 a.m. on February 9, 1942, as an emergency measure, the Nation shifted from 

standard time to "war time," and clock time in the several zones of the country was moved 

ahead 1 hour, or to 3 a.m. This made February 9 a 23-hour day. Time prior to 2 a.m.
4 TIME BASIS

February 9 as given herein refers to standard time; tine after 2 a.m. February 9 refers 

to war time. To convert war time to standard time, subtract 1 hour.

Records of daily discharge prior to February 9, 1942, published herein have been computed on the basis of standard time. Records subsequent to that date have been computed 

on the basis of war tis'e. The discharge given for February 9 is the nean for 23 hours. 

The mean discharge and runoff for the month of February have been computed from, the total 

second-foot-days for the nonth without adjustment for the fact that February 9 was a 

23-hour day. The snail error resulting from this procedure has been disregarded.

ACCURACY OF FIELD DATA AIID COMPUTED RESULTS

The accuracy of stream-flow data depends primarily on (1) the permanency 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 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 daily records are accurate within 

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

a higher percent. The records of monthly and yearly mean discharge and runoff are, in 

general, more accurate than the daily records.

Yield at some stations, as indicated by monthly means nay vary widely from natural yield, 

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

due to artificial causes, or other factors. For such stations figures of "second-feet per 

square mile" and "runoff in inches" are not published unless storage or diversion records 

are included indicating the extent of the regulation or diversion or unless satisfactory 

adjustments can be made for changes in contents of reservoirs or for other changes incident 

to use and control. Figures of second-feet per square mile and runoff in inches are also 

omitted if the drainage area includes large noncontributing areas or if the average annual 

rainfall over the drainage area is less than 20 inches.

Many gaging stations on streams in the irrigated areas of the United States are situated 

above nost of the diversions from those streams, and therefore 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 presents in summary the distribution of the flow past 

the station. The table of daily discharge affords opportunity for more detailed studies 

of the variation in flow. As further observations in each succeeding year may be expected 

to throw new light on data previously published, it should be borne in nind that such data 

are subject to revision in succeeding water-supply papers.

' Papers on surface water supply containing records from 1899 to date, grouped by years 

and drainage basins, are listed by number on page 7. 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, the data for 1910 to 1920 for any station in the 

area covered by part 3 are published In Water-Supply Papers 283, 303, 323, 353, 403, 433, 

453, 473, 503, which contain records for the Ohio River Basin for those years.

The records at most of the etatlons discussed In theee 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, the streams and points of measurement listed appearing In the same 

relative order as the streams and gaging stations In the body of the report. An Index or 

the records obtained prior to 1904 has been published In Water-Supply Paper 119.

Each of the reports on surface water supply for the year 1939, Issued as Water-Supply 

Papers 871 to 884 (see table on p. 7), contains a summary of yearly discharge at gaging 

stations In the area covered by that report. Gaging stations at which 10 or more complete years of record have been collected are represented. These summaries are available 

also as separate reprints.

From time to time reports 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 have been revised), as well as some records not contained in the annual series of water-supply papers. The following table gives the numbers and titles of these reports, arranged In alphabetical order by States and drainage 

basins.

Extremes.- Maximum gage height, 41.55 feet Apr. 22, just prior to levee breaks; maximum 

 discharge not determined but occurred Apr. 23 or 24 following numerous breaks in

levee system on both banks; minimum, 366 second-feet Aug. 9.

1924, 1938-42: Maximum gage height, that of Apr. 22, 1942; maximum discharge not

determined but occurred Apr. 23 or 24, 1942 following numerous breaks in levee system

on both banks; minimum, 34 second-feet Sept. 8-11, 1924.

Flood of May 1908 reached a stage of about 33.0 feet, present site and datum, from

information by Corps of Engineers, U. S. Army. (Discharge believed to have been

approximately same as that of April 23 or 2-i, 1942.) Levee system constructed in 1916. 

Remarks.- Records good except those for periods of no gage-height record or indefinite

stage-discharge relation, which are poor. No diversions above station except for

municipal supply. Flow partly regulated by reservoirs above Dallas.

Location.- Water-stage recorder, lat. 31°39', long. 95°47', at bridge on U. S. Highways 

79 and 84, 14 miles upstream from International-Great Northern Railroad bridge and 6 

miles northeast of Oakwood, Leon County. Datum of gage is 175.03 feet above mean sea 

level, datum of 1929.

Drainage area.- 12,840 square miles.

Records available.- July 1932 to September 1942. October 1923 to July 1932 at site 14 

miles downstream. (Records for January 1905 to September 1923 published in Watersupply Papers 850 and 878. Figures below 500 second-feet in these publications and 

minimum yearly discharge for water year 1923-24 published in Water-supply Paper 878, 

have been found to be in error.) U. S. Weather Bureau has collected gage-heightrecords in this vicinity since 1904.

Average discharge.- 19 years (1923-42), 4,954 second-feet.

Extremes.- Maximum discharge during year, 153,000 second-feet Apr. 29 (gage height, 51.64 

feet): minimum, 423 second-feet Aug. 10, 11.

Drainage area.- 17,500 square miles.

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

 ana some records of daily discharge), October 1940 to September 1942. U. S. Weather 

Bureau has collected gage-height records in this vicinity since 1903.

Extremes.- Maximum discharge observed during-year, 114,000 second-feet May 12 (gage 

height, 29.38 feet, observed at site of wire-weight gage; 29.00 feet observed at 

staff gage, stage affected by draw-down at pier to which gage is attached); minimum 

discharge not determined (affected by tides); minimum gage height observed, 5.0 

feet Aug. 12.

1938-42: Maximum discharge observed, that of May 12, 1942; minimum discharge not 

determined (affected by tides); minimum gage height observed, 2.5 feet Nov. 4, 1939.

A stage of 28.6 feet was reached May 8-11, 1922 from observation by U. S. Weather 

Bureau at their chain gage on railroad bridge upstream and probably away from pier 

disturbances.

Remarks.- Records good. Discharge not computed below about 4,000 second-feet due to 

tides affecting stage-discharge relation. Gage read once daily.

Cooperation.- Gage readings furnished by U. S. Weather Bureau.

is 357.1 feet above r.ean sea level, datum of 1929.

Drainage area.- 23,500 square miles, of which 9,240 square miles is probably noncontributing.

Records available.- September 1C98 to September 1942. January 1912 to September 1914, 

(monthly records only) published in Water-Supply Paper 850. U. S. Weather Eureau has 

collected gage-height records in this vicinity since 1900.

Average discharge.- 44 years, 2,764 second-feet.

Extremes.- Maximum discharge during year, 126,000 second-feet Apr. 25 (gage height, 35.70 

feet); minimum not determined.

1898-1942: Maximum discharge, 246,000 second-feet Sept. 27, 1936 (gage height, 

40.90 feet, levee on left bank was overtopped and broken by flood); minimum discharge 

for periods of daily record, 1898-1911, 1914-42, no flow Aug. 20, 21, 1918, and probably for several days In August 1923.

A stage of 39.7 feet was reached Dec. 3, 1913, when levee on left bank was broken 

by flood, from information by U. S. Weather Eureau.

Remarks.- Records good. Many small diversions above station do not appreciably affect 

flow, except during low stages. Flow partly regulated by Possum Kingdom'Reservoir on 

Brazos River (see p. 68 ) and Lake Waco, on, the Eosque River near Waco (capacity, 

39,000 acre-feet).

Discharge, in second-feet, water year October 1941 to September 1942

290, 4,500 feet upstream from Texas £ Hew Orleans Railroad bridge, 6.5 niles northwest 

of Hesnpstead, Waller County, and 0 niles upstream fron Caney Creek. Datum of gage is 

118.07 feet above mean sea level, daturi of 1929.

Drainage area.- 42,670 square miles, of which 9,240 square niles is probably noncontributing.

Records available.- October 1938 to September 1942. U. S. Weather Bureau has collected 

tags-height records in this vicinity at intermittent periods since 1903.

Extremes.- Maximum discharge during year, 90,500 second-feet Apr. 29 (gage height, 37.52 

feet, from floodnark); minimum observed, 810 second-feet Apr. 6.

1932-42: Maximum discharge observed, 116,000 second-feet IJov. 30, 1940 (gage 

height, 44.04 feet); minimum, 254 second-feet IJov. a, 1939.

Maximum stage known, 56.1 feet Dec. 8, 1913 (revised), from data furnished by 

engineers of Texas & New Orleans Railroad, secured at its bridge 4,500 feet downstream.

Re-narl:s.- Records fair. Gage read twice-daily, riore often during high water. Many small 

diversions above jage which do not appreciably affect flow except during low stages.

Discharge, in second-feet, water year October 1941 to September 1942

Records available.- October 1938 to September 1939 (gage heights only), October 1939 to 

September 1940 and February 1942 to September 1942 (gage heights, discharge measurements, and daily discharge above 3,000 second-feet), October 1940 to September 1941 

(discharge measurements only).

Extremes.- Maximum discharge observed during year, 71,000 second-feet tlay 1 (gage height, 

32.55 feet); minir/mm not determined (affected by tides).

1933-42: Maximum gage height observed, 34.12 feet, Dec. 5, 1940 (discharge not 

determined); minimum gage height, 1.54 feet Aug. 22, 1939 (affected by tides).

Maximum stage known, 35.3 feet on Dec. 11 or 12, 1913 (corrected); flood of 1899 

reached a stage 0.3 foot lower. Stages from information by local residents.

Remarks.- Records fair. Discharge for periods below 3,000 second-feet not piibllshed 

owing to effect from tides. Gage read twice dally, more often during high water. 

Considerable water diverted above station for irrigation and municipal supply.

Colorado River at Wharton, Tex.

Location.- Wire-weight gage, lat. 29 018'30", long. 96°06'15", on oridge on U. S. Highway 

96 in Wharton, Wharton County, 1,000 feet downstream from Texas & New Orleans Railroad bridge and 12 miles upstream from Jones Creek. Datum of gage is 65.42 feet 

above mean sea level, datum of 1929.

Drainage area.- 41,150 square miles, of which 11,800 square miles is probably noncontributing.

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

measurements only), October 1938 to September 1942. U. S. Weather Bureau has collected 

gage-height records in this vicinity since 1935.

Extremes.- Maximum discharge observed during year, 38,900 second-feet Apr. 9 (gage 

 height, 22.35 feet); minimum observed, 372 second-feet my 29 (affected by pumping). 

1919-25, 1938-42: Ifeximum discharge observed, 100,000 second-feet July 3, 1940

(gage height, 35.99 feet); no flow Aug. 6, 1925 (affected by pumping).

Maximum stage known, 38.9 feet, 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 above same height. Flood of June 20, 1935,

reached a stage of 38.2 feet, present datum (discharge, 159,000 second-feet, from

rating curve extended above 145,000 second-feet), furnished by U. S. Weather Bureau.

Flood of July 30, 1938, reached a stage of 37.4 feet, present datum, observed by

Geological Survey engineers (discharge, 145,000 second-feet).

Remarks.- Records fair. Gage read twice daily, more often during high water. Diversions 

above station for irrigation and municipal supply. Regulation sane as that for 

Colorado River at Austin. 

Cooperation.- Gage-height record collected in cooperation with the U. S. Weather Bureau.

Discharge, in second-feet, water year October 1941 to September 1948

Smlthville, Bastrop County. Datum of gage is 327.9 feet above mean sea level, datum of 

1929.

Drainage area.- 1.48 square miles (area above dam). 

Records available.- October 1939 to September 1942.

Extremes.- Maximum discharge during year, 670 second-feet Oct. 30 (no flow passed over 

spillway); maximum gage height, 21.34 feet Oct. 31; no flow at times.

1939-42: Maximum discharge, 1,870 second-feet June 30, 1940 (gage height, 24.82 

feet); maximum gage height, 24.96 feet June 30, 1940; no flow at times.

Remarks.- Records fair. They represent flow into Buescher Lake. No flow from area except 

during and immediately following precipitation. Discharge below gage height 22.27 feet 

(spillway crest) determined from change in contents in lake; that above gage height 

22.27 feet determined by algebraic summation of flow over spillway (computed from 

spillway curve) and change in contents in lake (computed from capacity curve and 

reduced to equivalent second-feet). There was no flow over spillway during year. 

No adjustments made for evaporation or seepage losses. Capacity of lake, 255 acrefeet. No diversions above station or from lake.

Discharge, in second-feet, water year October 1941 to September 1942

GUADALUPE RIVER BASIN 137

Comal River at New Brauniexu, Tex.

Location.- Water-stage recorder, lat. 29°42'05", long. 98°07'10", 200 feet upstream from 

San Antonio Street viaduct in New Braunfels, Comal County, and 1.1 miles upstream 

from mouth. Datum of gage is 582.80 feet above mean sea level, datum of 1929.

Drainage area.- 94 square miles. Ordinary flow of river comes from springs; drainage 

area of stream not applicable.

Records available.- December L927 to September 1942.

Average discharge.- 10 years (1932-42), 332 second-feet.

Extremes.- Maximum gage height during year, 13.14 feet, Sept. 8 (affected by backwater 

from Guadalupe River; discharge not determined); minimum, 221 second-feet (regulated) 

May 18; minimum daily, 304 second-feet May 23.

1927-42: Maximum gage height, 30.71 feet June 15, 1935, from floodmarks (affected 

by backwater from Guadalupe River; discharge not determined); minimum discharge, about 

142 second-feet (regulated) Dec. 11, 1928 (gage height, 2.12 feet); minimum daily, 245 

second-feet July 17, 20, 1939.

Maximum stage known, 35.4 feet December 1913, from floodmarks (probably some backwater from Guadalupe River).

Remarks.- Records good except those for periods of no gage-height record or backwater 

effect, which are poor. Flow partly regulated by steam power plant half a mile above 

station. Entire flow of river from Comal Springs, about 1 mile upstream, except during periods of local rain. Springs emerge from the Edwards limestone in the Balcones 

fault zone.

Records available.- October 1923 to September 1942.

Average' discharge.- 19 years, 158 second-feet.

Extremes.- Maximum discharge during year, 19,600 second-feet Oct. 24 (gage height, 12.40 

feet); minimum, 23 second-feet Aug. 13-16, 27-30.

1923-42: Maximum discharge, 222,000 second-feet July 13, 1939 (gage height,' 26.40 

feet), from rating curve extended above 40,000 second-feet on basis of float measurement (110,000 second-feet) and slope-area determination (213,000 second-feet): minimum, 

7.8 second-feet Nov. 3-15, 18, 1934,

Flood of Sept. 21, 1923 reached a stage of 26.5 feet (discharge, 226,000 second-feet,

Records available.- October 1923 to September 1942. July 1915 to June 1918 at site 4

 miles upstream. 1914-17 and since 1922 (gage heights only) in reports of U. S. 

' Weather Bureau.

Average discharge.- 19 years, 328 second-feet.

Extremes.- Maximum discharge observed during year, 10,200 second-feet Sept. 8 (gage

 height, 17.40 feet); no flow June 28 to July 2, Aug. 1-29.

1923-42: Maximum discharge, 82,600 second-feet June 18, 1935 (gage height, 32.4 

feet, from floodmarks), by slope-area method; no flow at times.

Remarks.- Records Rood. Part of the flow of Nueces River and its tributaries enters the

 KMwards limestone in the Balcones fault zone which crosses the basin Just north of 

the Uvalde. At low stages most of the headwater flow enters this formation. Lowwater flow partly regulated by small storage reservoirs above station; most of it is 

diverted above station by pumping. Gage read once daily.

Cooperation.- Gage-height record furnished by U. S. Weather Bureau.

Interval, 10 feet; the U. S. Soil Conservation Service In connection with a slltation 

survey, determined the capacity in 1942 to be 43,400 acre-feet, which survey also 

determined the original capacity to be 54,000 acre-feet, indicating a loss of 10,600 

acre-feet by siltation). Part of the flow of the Nueces River and Its tributaries 

enters the Edwards limestone in the Balcones fault zone which crosses the basin Just 

north of Uvalde in an east-west course. At low stages most of the headwater flow 

enters this formation. About 5,000 acres irrigated from river above station and 

about 12,000 acres Jointly from river and wells.

Frio River at Calllham, Tex.

Location.- Water-stage recorder and concrete control, lat. 28°29'30", long. 98°20'45", at 

bridge on Calliham-Whitsett highway, 1 mile north of Calliham, McMullen County, and 

9.7 miles downstream from San Miguel Creek. Datum of gage is 153.47 feet above mean 

sea level.

Drainage area.- 5,491 square miles.

Records available.- October 1924 to April 1926, April 1932 to September 1942.

Average discharge.- 11 years (1924-25, 1932-42), 329 second-feet.

Extremes.- Ifeximum discharge during year, 23,700 second-feet July 7 (gage height, 32.00 

feet); minimum, 3.4 second-feet June 22.

1924-26, 1932-42: Fkximum discharge, 109,000 second-feet July 6, 1932 (gage height, 

39.20 feet, from floodmarks), by slope-area method; no flow at times.

Remarks.- Records good. Part of the flow of the Ffio River and its tributaries enters 

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

Uvalde in an east-west course. At low stages all of the headwater flow, with few exceptions, enters this formation. Diversions for irrigation above station.

Discharge, in second-feet, water year October 1941 to September 1942

Sabinal River seepage investigation

A series of discharge measurements was nade on each day May 8, 18, and Aug. 5, 1942 on 

the Sabinal River and tributaries in Texas, in reaches 9.5 and 17.5 niles in length between points below Utopia and a point 6.0 niles north of Sabinal, Uvalde County. The ' 

investigations were nade during periods of constant stage of the river except as noted, and 

the determinations of gain or loss represent normal conditions.

RIO GRANDE BASIN 249

Pecos River near Artesla, N. Hex.

Location.- Water-stage recorder, lat. 32°50'10", long. 1040 19'30", In WsWWi sec. 18, T. 

 17 S., R. 27 E., at bridge on Artesla-Lovlngton highway, 4.2 miles east of Artesla, 

6.5 miles north of mouth of Rio Penasco, and 16.5 miles north of McMlllan Dam.

Drainage area.- 15,300 square miles (contributing area).

Records available.- March 1905 to September 1925 and October 1931 to February 1936

(published as Pecos River near Dayton), and February 1936 to September 1942 lr report 

of Geological Survey. March 1905 to December 1931 In reports of State engineer.

Extremes.- Maximum discharge during year, 25,500 second-feet Oct. 2, from rating curve 

extended above 10,600 second-feet by slope-area method and logarithmic plotting; 

maximum gage height, 12.43 feet Sept.. 4; minimum dally discharge, 70 second-feet 

Aug. 8.

1905-42: Maximum gage height, 15.9 feet Sept. 18, 1919, site and datum then in 

use (discharge not determined). Flood of May 30, 1937 reached a discharge of 51,500 

second-feet (gage height, 14.7 feet), by slope-area method; no flow Aug. 17-24, 1934.

Remarks.- Records fair. Diversions above station for irrigation. Flow partly regulated 

by Alaciogordo Reservoir (see p.185). Discharge represents inflow to Lake McMillan, 

which stores water for irrigation of about 25,000 acres of Carlsbad project.

Cooperation.- Gage-height record collected in cooperation with Bureau of Reclamation.

Discharge, in second-feet, water year October 1941 to bepiemoer 1948

Principal diversions from Pecos River between Red Bluff Reservoir and Imperial, Tex.

Records of discharge are collected for eight canals that divert water from Pecos 

River between Red Bluff Reservoir and Imperial, Tex. Each of these canals is equipped 

with a water-stage recorder for collecting gage-height records. All stations are located 

within 2 miles of canal head Rate except as noted herein. Two stations were relocated 

during year; latitude and longitude herein are for latest locations. Water diverted by 

these canals Is used for Irrigation of lands on both sides of Pecos River In Reeves, 

Ward, and Pecos Counties. Stations prior to 1941 were published separately (dally discharge figures for the earlier records). Gage-height records collected In cooperation 

with Red Bluff Water Power Control District, Pecos, Tex.

Las Mbras Springs at Brackettville, Tex.

Location.- Staff gage, lat. 29 C 18', long. 100°25', in spring pool at Brackettville, 

Klnney County, about a quarter of a mile upstream from bridge on Brackettvilie-Fort 

Clark road. Datum of gage is 1,095.0 feet above mean sea level (Texas Highway Department bench mark).

Records available.- December 1895 to August 1938 (occasional miscellaneous aiscnarge 

measurements), September 1938 to September 1942 (discharge measurements only).

Extremes.- 1895-1942: Maximum discharge measured, 60 second-feet (by Prof. T. U. Taylor) 

June 30, 1899; minimum measured, 5.8 second-feet July 30, 1928.

Remarks.- Discharge measurements represent total flow of springs. Flow of springs

emerges from limestone outcrop in Ealcones fault zone and responds to local rainfall on 

Edwards Plateau. Elevation of pool regulated by outlet gate and discharge is affected 

to large extent. City of Brackettville and U. S. Army (about 1 second-foot, for Fort 

Clark) divert water irom pool for domestic and recreational uses.
