SURFACE WATER SUPPLY OF WESTERN GULF OF MEXICO BASINS, 1947

SCOPE OP WORK

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

stage and flow made on streams, lakes, and reservoirs in the United States during the 

water year ending September 30, 1947. 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 11,100 gaging s-tations 

in the 48 States and also at many in the Territories of Alaska and Hawaii. In July 1947, 

5,810 gaging stations, including those in Hawaii, were being maintained by the Geological 

Survey and cooperating organizations. Miscellaneous discharge measurements were made 

during the water year at many other points.

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

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

kind is acknowledged in connection with the description of each station affected; cooperation of the second kind is acknowledged,. under the heading "Cooperation," in the introductory matter that precedes the gaging-station records in each volume. In the present 

volume, the section on cooperation of the second kind appears on page 13.

DEFINITION OP TERMS

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

herein are defined as follows:

"Second-feet" is an abbreviation for "cubic feet per second." A second-foot is the 

rate of discharge of 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 mile" is the average number of cubic feet of water flowing per 

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

"Seoond-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.

"Contents" is a term applied to the volume of water in a reservoir- It is computed on 

the basis of a level pool and does not include bank storage unless otherwise indicated.

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 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 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 in figure 1.

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

may 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 "shiftingcontrol" method, described above.

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

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. For those 

stations at which the stage-discharge relation is affected by ice, the days included in 

the periods of ice effect either are indicated in ths table by symbols referring to a 

footnote that states this fact or are given in a general note following the table. The 

days on which discharge measurements were made during or between periods of ice effect, 

shortly before the first period, or shortly after the last period are similarly indicated 

by a footnote.

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 as 

determined from the best available maps, and information in regard to diversions that 

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

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

number of years indicated. It is given only for stations for which there are 10 or more 

complete years of record. Under "Extremes" are given the maximum discharge and gage 

height; the minimum discharge if there is little or no regulation; the minimini daily 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 or a nonrecording gage read at the time of the crest. Likewise the minimum discharge 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 a station at which 

the'drainage area of the stream is less than 10 or more than 10,000 square miles or at 

which, on most days, the peak discharge exceeds the mean discharge by less than 10 percent

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 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 either once-daily readings of the gage, the mean of twice-daily readings, or 

the mean gage height determined from gage-height graphs based on gage readings. For 

periods of rapidly changing stage, the dally 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 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, 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.
SURFACE WATER SUPPLY, 1947, PART 8 5

ACCURACY OF FIELD DATA AND 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 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 accurate than the daily records.

Yield at some stations as indicated by monthly means may 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 or reservoirs 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 its inclusion is indicated. Even at those Stations 

where adjustments are made, in some instances large errors in computed yields may occur 

when relatively large negative adjustments are applied or when evaporation is large in 

comparison with the observed discharge. 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 most of the diversions from those streams, and therefore the discharge recorded 

does not show the water supply available for further development, as prior aopropriations 

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 mind 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 8. The data for any particular gaging 

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

The records at most of the stations discussed in these reports extend over a series of 

years. Miscellaneous measurements at many points other than regular gaging stations have 

been made each year and are published under "Miscellaneous discharge measurements" at the 

end of each report, 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 of 

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

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

Papers 871 to 884 (see table on p. 8), contains, for the area covered by that report, a 

sum-nary of yearly discharge at gaging stations at which 10 or more complete years of record 

have been collected. These summaries are available also as separate reprints.

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 selected areas in Texas, from 3 areas of less than 200 acres each near Waco 

and 5 areas of less than 30 acres each near Garland, beginning in 1938. These records are in the 

files of the Soil Conservation Service.

K. 1 K. Louisiana meridian, at bridge on State Highway 370, I? miles upstream from 

New Orleans, Texas & Mexico Railroad bridge, 1 mile downstream from bridge on State 

Highway 26, and l£ miles northwest of Crowley. Datum of gage is 2.17 feet below mean 

sea level (Louisiana Geodetic Survey bench mark).

Records available.- October 1942 to September 1947.

Extremes.- Maximum discharge during year, 10,200 second-feet Jan. 14; maximum gage height, 

is.au feet Jan. 15; minimum discharge not determined.

1942-47: Maximum discharge, 12,400 second-feet July 7, 1946; maximum gage height, 

20.89 feet July 8, 1942, no flow at times in most years.

Maximum stage known, 26.57 feet, in August 1940, from floodmarks indicated by local 

resident, result of hurricane flood accompanied by high tides.

Remarks.- Records fair above 300 second-feet and poor below. Gage read twice daily. Discharge above about 200 second-feet computed by using rate of change in stage as a 

factor. Large diversions below station for irrigation by pumping affect stage-discharge relation. Records include waste water- from rice fields above station that were 

irrigated from ground-water supplies.

Discharge, in second-feet, water year October 1946 to September 1947

reservoir) upstream from Mason Creek, 9.0 miles (6.4 miles by reservoir) upstream from 

reservoir outlet works. Datum of both gages is 0.3 foot below mean sea level, datum 

of 1929, Galveston-Houston supplementary adjustment and Houston supplementary adjustment of 1943.

Drainage area.- 150 square miles at outlet works; 105 square miles at upper gage. 

Records available.- August 1945 to September 1947.

Extremes.- Maximum gage height at dam during year, 81.57 feet Nov. 12, 13 (contents, 105 

acre-feet); maximum at upper gage, 97.0 feet Nov. 11.

1945-47: Maximum gage height at dam, 90.4 feet Aug. 30, 1945 (contents, 11,240 acrefeet); maximjm at upper gage, 98.6 feet Aug. 28, 1945.

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

feet in December 1935, from floodmark about 1,100 feet to right of and 1,100 feet downstream from upper gage.

Remarks.- Reservoir is formed by rolled-earth dam 72,844 feet long. Dam completed Feb. 3, 

I94b, 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, four of which are 

uncontrolled. The middle conduit is controlled by two vertical-lift steel gates and 

remains closed except during recession of large floods or during emergencies. Capacity, 

127,900 acre-feet between gage heights 75.0 feet (bottom of conduits) and 101.9 feet 

(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 feet or 

higher at dam.

Cooperation.- Capacity table furnished by Corps of Engineers.

Legation.- Mercury U-tube gage, lat. 32°52', long. 98"26", in powerhouse at dam on Brazos 

River, 2.6 miles upstream from Loving Creek and 11.3 miles southwest o. Graford, Palo 

Pinto County. Datum of gage is 0.10 foot above mean sea level, datum of 1929 (levels 

by Brazos River Conservation and Reclamation District).

Drainage area.- 22,550 square miles, of which 9,240 square miles is probably noncontributmg.

Records available.- March 1941 to September 1947.

Extremes.- Maximum contents observed during year, 709,500 acre-feet May 19 (gage height, 

yyy.a feet); minimum observed, 495,600 acre-feet Sept. 30 (gage height, 986.4 feet). 

1941-47: Maximum contents observed, 743,700 acre-feet Oct. 5, 1941 (gage height, 

1,001.0 feet); minimum observed, 378,900 acre-feet Feb. 18-27, 1944 (gage height, 977.3 

feet).

Remarks.- Reservoir is formed by reinforced concrete dam of flat slab deck, massive tattress type, with nine roof-weir (modified bear-trap) type gates, two bulkhead sections, 

and earthen dike section. Dam completed and storage began Mar. 21, 1941. Total capacity, 724,700 acre-feet (gage height, 1,000.0 feet, top of closed roof-weir gates). 

Usable capacity for power development, 698,900 acre-feet between gage heights 911.5 

feet (sill of powerhouse penstock) and 1,000.0 feet (top of closed roof-weir gates). 

Water below gage height 911.5 feet can be withdrawn through high-pressure outlet down

Cooperation.- Records of daily gage height and capacity table furnished by Brazos River 

conservation and Reclamation District.

Brazos River near Palo Pinto, Tex.

Location.- Water-stage recorder, lat. 32°51'45", long. 98°18'10", at bridge on Palo Pinto- 

(irarord highway, 300 feet downstream from Dark Valley Creek, 6| miles north of Palo 

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

gage is 831.23 feet above mean sea level, datum of 1929.

Drainage area.- 22,760 square miles, of which 9,240 square miles is probably noncontributing.

Records available.- November 1933 to September 1947. January 1924 to November 1933 at 

site near Mineral Wells.

Average discharge.- 13 years (1934-47), 1,253 second-feet.

Extremes (regulated).- Maximum discharge during year, 21,100 second-feet May 19 (gage

neignt, iu.4t> reet); minimum not determined, probably occurred during period of no gageheight record.

1933-47: Maximum discharge, 64,900 second-feet May 20, 1935, from rating curve extended above 32,000 second-feet; maximum gage height, 17.42 feet Oct. 17, 1942; no flow 

at times.

Maximum stage known was reached by flood of 1876, according to data of Corps of Engineers, and was several feet higher than any subsequent flood. A stage of about 24.0 

feet was reached in June 1930, from information by local residents.

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

Flow largely regulated by Possum Kingdom Reservoir (see p. 89) and several smaller 

reservoirs above Nugent in Clear Pork Basin, having a combined capacity of 831,000 acrefeet. Many small diversions above station for irrigation, municipal supply, and oilfield operation. Records of water analyses for water year 1947 are given in WaterSupply Paper 1102.

graph based on once-daily readings of outside gage by U. S. Weather Bureau.
94 BRAZOS RIVER BASIN

Brazos River near Marlin, Tex.

Location.- Wire-weight gage, lat. 31°17'20", long. 96°58'10", at bridge on State Highway 

lay, 1 mile upstream from Deer Creek and 4.5 miles southwest of Marlin, Falls County. 

Datum of gage is 312.15 feet above mean sea level, datum of 1929.

Drainage area.- 29,150 square miles, of which 9,240 square miles is probably noncontributing.

Records available.- October 1938 to September 1947.

Extremes.- Maximum discharge during year, 25,200 second-feet May 21 (gage height, 14.40 

I'eet, from graph based on gage readings); minimum observed, 320 second-fee-t (regulated) 

Sept. 24.

1938-47; Maximum discharge, 132,000 second-feet May 3, 1944 (gage height, 33.3 

feet, from floodmark); minimum not determined.

Maximum stage known, 35.8 feet Dec. 3 or 4, 1913, from information by local residents. Flood of Sept. 28, 1936, reached a stage of 35.2 feet.

Remarks.- Records good. Gage read twice daily, oftener during high stages. Flow partly 

regulated by reservoirs above Waco. Many small diversions above station for irrigation, municipal supply, and oil-field operation do not appreciably affect flow.

Discharge, in second-feet, water year October 1946 to September 1947

d Doubtful gage-height record; discharge computed on basis of records for stations near Marlln and 

near Hempstead.

f Computed on basis of partly estimated gage-height record.

Mote.- No gage-height record Jan. 1-13, June 5-11; discharge computed on basis of recorded range 

In stage, weather records, U. S. Weather Bureau gage-height record for Brazos River near Valley 

Junction, and records for stations near Marlln and near Hempstead.
BRAZOS RIVER BASIN

Brazos River near Hempstead, Tex.

Location.- Wire-weight gage, lat. 30°07'25", long. 96°11'00", at bridge on U. S. Highway 

290, 4,500 feet upstream from Texas & New Orleans Railroad bridge, 6.5 miles northwest 

of Hempstead, Waller County, and 8 miles upstream from Caney Creek. Datum of gage is 

118.07 feet above mean sea level, datum of 1929.

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

Records available.- October 1938 to September 1947. U. S. Weather Bureau has collected 

gage-neight records in this vicinity at intermittent periods since 1903.

Extremes.- Maximum discharge during year, 57,000 second-feet Jan. 20; maximum gage height, 

lib.73 feet Jan. 20; minimum discharge observed, 720 second-feet Sept. 28.

1938-47: Maximum discharge, 116,000 second-feet Nov. 30, 1940 (gage height, 44.04 

feet); minimum, 254 second-feet Nov. 8, 1939. *

Maximum stage known, 56.1 feet Dec. 8, 1913, from data by engineers of Texas & New 

Orleans Railroad, obtained at bridge 4,500 feet downstream.

Remarks.- Records fair. Gage read twice daily, oftener during high stages. Flow partly 

regulated by reservoirs above Waco. Many small diversions above station for irrigation, 

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

Discharge, in second-feet, water year October 1946 to September 1947

records in this vicinity from 1903 to 1929.

Average discharge.- 40 years, 405 second-feet.

Extremes.- Maximum discharge during year, 21,200 second-feet May 12 (gage height, 17.92 

feet); minimum, 1.7 second-feet May 8, Aug. 14, 15.

1907-47: Maximum discharge, 75,400 second-feet Sept. 18, 1936 (gage height, 28.6 

feet); no flow at times.

Maximum stage known, about 36.0 feet sometime in 1884, present site and datum, 

from information by local residents. A stage of about 32.0 feet occurred Aug. 6, 1906, 

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

Remarks.- Records good. Small diversions above station for irrigation affect low flow.

Discharge, in second-feet, water year October 1946 to September 194?

measurements only), October 1938 to September 1947. June to November 1901, daily 

records published in U. S. Department of Agriculture, Office of Experiment Stations, 

Bulletin No. 119. U. S. Weather Bureau has collected gage-height records in this 

vicinity since 1935.

Average discharge.- 14 years (1919-21, 1922-25, 1938-47), 3,562 second-feet.

extremes.- Maximum discharge during year, 27,300 second-feet Nov. 6 (gage height, 16.98 

feet, from graph based on gage readings); minimum observed, 725 second-feet (regulated) 

May 9.

1919-25, 1938-47: Maximum discharge observed, 100,000 second-feet July 3, 1940 

(gage height, 35.99 feet); no flow Aug. 6, 1925 (result of 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 about 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 good. Gage read twice daily. Diversions above station for irrigation 

ana municipal supply. Regulation same as that for Colorado River at Austin. Records 

of water analyses for water year 1947 are given in Water-Supply Paper 1102.

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

Discharge, in second-feet, water year October 1946 to September 1947

Lake Nasworthy near San Angelo, Tex.

Location.- Water-stage recorder, lat. 31°23'15", long. 100°28'40", 250 feet upstream from 

Nasworthy Dam on South Concho River, half a mile downstream from Middle Concho River, 

and 6 miles southwest of San Angelo, Tom Green County. Datum of gage is 1,840.0 feet 

above mean sea level, datum of 1929.

Drainage area.- 2,659 square miles, of which 152 square miles is probably noncontributing.

Records available^- March 1930 to September 1947.

Extremes.- Maximum contents during year, 10,740 acre-feet Dec. 11 (gage height, 30.15 

TeeTTT minimum, 3,550 acre-feet Sept. 30 (gage height, 22.73 feet).

1930-47: Maximum contents, 26,900 acre-feet Sept. 15, 1936 (gage height, 38.36 

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

12.6 feet).

Remarks.- Lake is formed by 4,900-foot earthen dam (contains 2 emergency spillways, 300 

an3~800 feet in length) and 438-foot concrete service spillway, with a bank of 15 

taintor gates. Dam completed and storage began Mar. 28, 1930. Total capacity, 10,740 

acre-feet (gage height, 30.2 feet top of taintor gates). Usable capacity, 10,740 acrefeet between gage heights -4.0 feet (revised) (bottom of two 36-inch gates) and 30.2 

feet (top of taintor gates). Figures of contents shown herein represent total contents 

of lake, and are unadjusted for slltation. A siltatlon survey made bythe Soil Conservation Service of the U. S. Department of Agriculture indicates a 10 percent capacity loss from siltation in 8.2 years (1930-39). Water used for San Angelo municipal 

supply.

Dove Creek near Knickerbocker, Tex.

Location.- Water-stage recorder, lat. 31°12', long. 100°41', in Irion County, upstream

 from Knickerbocker-Rawls ranch road crossing, a quarter of a mile downstream from 

Stilson diversion dam, three-quarters of a mile upstream from Kepler Creek, 2 miles 

downstream from Dove Creek Spring, and about 7 miles southwest of Knickerbocker, 

Tom Green County.

Records available.- November 1944 to September 1947.

Extremes.- Maximum gage height during year not determined; no flow at times.

 1955-47: Maximum gage height, 7.08 feet July 6, 1945 (discharge not determined); 

no flow at times.

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

 poor. As the primary purpose of this station is to measure low or spring flow, discharge 'fill not be computed for flows greater than about 15 second-feet. Diversions 

for irrigation above station.

Remarks.- Records good. Records given herein represent flow into Buescher Lake. No 

runoff except during and immediately following precipitation. Discharge below gage 

height 22.27 feet (spillway crest) determined from change in contents of lake; that 

above gage height 22.27 feet determined by algebraic summation of flow over spillway 

(computed from spillway curve) and change in contents of 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 

acre-feet. No diversions above station or from lake.

182 NUECES RIVER BASIN

Nueces River near Ma this,- Tex.

Location.- Water-stage recorder, lat. 28°02', long. 97°52', at bridge on U. S. Highway 

69, 200 feet downstream from Texas & New Orleans Railroad bridge, 0.8 mile downstream 

from Lake Corpus Christ! Dam, and 4 miles southwest of Mathls, San Patricio County. 

Datum of gage is 27.53 feet above mean sea level, datum of 1929.

Drainage area.- 16,660 square miles.

Records available.- August 1939 to September 1947.

Extremes.- Maximum discharge during year, 33.700 second-feet Oct. 16 (gage height, 32.92 

rest); minimum, 59 second-feet (regulated) Apr. 24, 25.

1939-47: Maximum discharge, 49,400 second-feet July 12, 1942 (gage height, 37.38 

feet); minimum, 3.7 second-feet (regulated) Aug. 15, 1940; minimum daily, 6.8 secondfeet (regulated) Aug. 15, 1940.

Maximum stage known, 39.9 feet in September 1919 at railroad bridge 200 feet upstream, from floodmark identified by Texas & New Orleans Railroad engineers.

Remarks - Records fair. Flow regulated by Lake Corpus Christ! Reservoir. (Original capacity at spillway crest, about 64,000 acre-feet, as determined by Texas State Board of 

Water Engineers, computed from Geological Survey advance topographic sheets, scale 

1:48,000, contour interval, 10 feet; the U. S. Soil Conservation Service, in connection 

with a siltation survey, determined capacity in 1942 to be 43,400 acre-feet, which survey also determined original capacity to be 54,000 acre-feet, indicating a loss of 

10,600 acre-feet by siltation.) 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. About 5,000 

acres irrigated from river above station, and about 12,000 acres jointly from river and 

wells above station.

Discharge, in seccnd-feet, water year October 1946 to September 1947

Leona River seepage investigations

A series of five discharge measurements was made on Leona River and tributaries, Texas. 

The series was made in March between the old Uvalde-Pearsall road bridge, 1.7 southeast of 

Dvalde, Uvalde County, and Kincaid Camp, 9.5 miles southeast of Dvalde. Measurements were 

made to establish relation between flow of river and water table in the river valley. See 

report of Texas Board of Water Engineers (p. 9), "Relationship of Ground Water to the Discharge of the Leona River in Uvalde and Zavalla Counties, Tex." - April 1947. Investigation was made during a constant stage and determinations represent natural conditions. 

Distances along river measured on tracings from aerial photographs and D. S. Department 

of Agriculture soil-survey map.

Principal diversions from Rio Lucero, N. Mex.

Records of discharge are collected for five ditches that divert water from the Rio 

Lucero below gagirfg station on that stream near Arroyo Seco. Each of these ditches is 

equipped with a water-stage recorder for collecting gage-height records. Water diverted 

by these ditches is used for irrigation in the valley of the Rio Lucero below the gaging 

station near Arroyo Seco.

270 RIO GRANDE BASIN

Principal diversions from Nambe Creek, H. Mex.

Records of discharge are collected for 11 ditches that divert water from Nambe Creek 

between Nambe diversion dam, 2? miles upstream from Nambe, and confluence with Rio Tesuque. 

Each of these ditches is equipped with a water-stage recorder for collecting gage-height 

records and each one, except Las Joyas, with a Parshall flume. Water diverted by these 

ditches is used for irrigation in the valley of Nambe Creek, except that diverted by Jacona 

ditch, which is used for irrigation on the left bank of Rio Pojoaque below Rio Tesuque.

Nambe Canal diverts from right bank in SE£ sec. 24, T. 19 N., R. 9 E., 1,000 feet upstream 

rrom gaging station on Nambe Creek near Nambe. Records available, May 1932 to September 

1947 (except winter periods for water years 1942-46).

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 gate except as noted herein. 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 (daily discharge figures for 

the earlier records). Gage-height records collected in cooperation with Red Bluff Water 

Power Control District, Pecos, Tex.

Comanahe Springs at Fort Stockton, Tex.

Location.- Water-stage recorder, lat. 30°53', long. 102°52', on outlet canal of Pecos 

Ooonty Water Improvement District No. 1, in eastern outskirts of Port Stockton, Pecos 

County, a quarter of a mile upstream from bridge on U. S. Highway 290 and 0.5 mile 

downstream from head of springs. Datum of gage is 2,922.8 feet above mean sea level, 

datum of 1929.

Records available.- February 1941 to September 1947. 1899, 1904, 1919, 1922, 1924-25, 

Jtyaa-41 (occasional discharge measurements published as miscellaneous measurements).

Extremes.- Maximum daily discharge during year, 45 second-feet Feb. 25 to Mar. 11; mlnImum daily, 39 second-feet Sept. 13-30.

1941-47: Maximum daily discharge, 54 second-feet Jan. 30, 1942; minimum daily, 39 

second-feet Aug. 12 to Sect. 21, 1945, Sept. 13-30, 1947.

Maximum discharge measured prior to 1941, 66 second-feet June 23, 1899; minimum 

measured, 38.7 second-feet July 14, 1936.

Remarks.- Records good. Discharge represents total flow of springs exclusive of surface 

runoff from precipitation. Spring flow fluctuates slowly; aquatic growth changes 

stage-discharge relation frequently; daily discharge determined from hydrograph based 

on discharge measurements. About 6,000 acres of land irrigated below station.

Discharge, in second-feet, water year October 1946 to September 1947

Peak discharge.- Oct. 8 (7:30 p.m.) 6,140 sec.-ft.; May 15 (5:00 a.m.) 5,310 sec.-ft. 

Las Moras Springs at Brackettville, Tex.

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

Rinney County, a quarter of a mile upstream from bridge on Brackettville-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 discharge 

measurements), September 1938 to September 1947 (discharge measurements only).

Extremes - 1895-1947: Maximum discharge measured, 60 second-feet (by Prof. T. U. Taylor) 

June 30, 1899; minimum measured, 5.7 second-feet July 21, 1945.

Remarks.- Discharge measurements represent total flow of springs. Springs issue from

limestone in Balcones fault zone and respond to rainfall on Edwards Plateau. Elevation 

of spring pool is regulated by outlet gate which materially affects discharge. City of 

Brackettville diverts water from spring pool for domestic and recreational uses.
