SURFACE WATER SUPPLY OF WESTERN GULF 

OF MEXICO BASINS, 1925

AUTHORIZATION AND SCOPE OF WORK

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

measurements of streams in the United States during the year ending 

September 30, 1925.

The data presented in these reports were collected by the United 

States Geological Survey under the following authority contained in 

the organic law (20 Stat. L., p. 394):

Provided, That this officer [the Director] shall have the direction of the Geological Survey and the classification of public lands and examination of the 

geological structure, mineral resources, and products of the national domain.

The work was begun in 1888 in connection with special studies 

relating to irrigation. Since the fiscal year ending June 30, 1895, 

successive appropriation bills passed by Congress have carried the 

following item:

For gaging the streams and determining the water supply of the United States, 

and for the investigation of underground currents and artesian wells, and for 

the preparation of reports upon the best methods of utilizing the water resources.

In this work many private and State organizations have cooperated, either by furnishing records or by assisting in their collection. 

Acknowledgments for cooperation of the first kind are made in connection with the description of each station affected; cooperation of 

the second kind is acknowledged on page 10.

Measurements of stream flow have been made at about 5,120 

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

the Hawaiian Islands. In July, 1925, 1,710 gaging stations were 

being maintained by the Geological Survey and the cooperating

organizations. Many miscellaneous discharge measurements were 

made at other points. In connection with this work data were also 

collected in regard to precipitation, evaporation, storage reservoirs, 

river profiles, and water power in many sections of the country arid, 

will be made available in water-supply papers from time to time.

DEFINITION OF TERMS

The volume of water flowing in a stream the "run-off"or "discharge" is expressed in various terms, each of which has become 

associated with work of a certain class. These terms may be divided 

into two groups (1) those that represent a rate of flow, as secondfeet, gallons per minute, miner's inches, and discharge in secondfeet per square mile, and (2) those that represent the actual quantity 

of water, as run-off in inches, acre-feet, and millions of cubic feet. 

The principal terms used in this series of reports are second-feet, 

second-feet per square mile, run-off in inches, and acre-feet. They 

may be defined as follows:

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

A second-foot is the rate of discharge of water flowing in a channel 

of rectangular cross section, 1 foot wide and 1 foot deep, at an average 

velocity of 1 foot per second. It is generally used as a fundamental 

unit from which others are computed.

"Second-feet per square mile" is the average number of cubic 

feet of water flowing per second from each square mile of area drained, 

on the assumption that the run-off is distributed uniformly both as 

regards time and area.

"Run-off in inches" is the depth to which an area would be covered if all the water flowing from it in a given period were uniformly 

distributed on the surface. It is used for comparing run-off with 

rainfall, which is usually expressed in depth in inches.

An "acre-foot," equivalent to 43,560 cubic feet, is the quantity 

required to cover an acre to the depth of 1 foot. The term is commonly used in connection with storage for irrigation.

The following terms not in common use are here defined:

"Stage-discharge relation," an abbreviation for the term "relation 

of gage height to discharge."

"Control," a term used to designate the section or sections of the 

stream below the gage which determine the stage-discharge relation 

at the gage. It should be noted that the control may not be the 

same section or sections at all stages.

The "point of zero flow" for a given gaging station is that point 

on the gage the gage height at which water ceases to flow over the 

control.
SURFACE WATER SUPPLY, 1925, PART VIII 3 

EXPLANATION OF DATA

The data presented in this report cover the year ending September 

30, 1925. At the beginning of January in most parts of the United 

States much of the precipitation in the preceding three months is 

stored in the form of snow or ice, in ponds, lakes, and swamps, or 

as ground water, and this stored water passes off in the streams 

during the spring break-up. At the end of September, on the other 

hand, the only stored water available for run-off is possibly a small 

quantity in the ground; therefore, the run-off for the year beginning 

October 1 is practically all derived from precipitation within that year.

The base data collected at gaging stations consist of records of 

stage, measurements of discharge, and general information used to

FIGUEE 1. Typical gaging station

supplement the gage heights and discharge measurements in determining the daily flow. The records of stage are obtained either from 

direct reading on a staff 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. 

A typical gaging station, equipped with water-stage recorder and 

measuring cable and car, is shown in Figure 1.

From the discharge measurements rating tables are prepared that 

give the discharge for any stage. The application of the daily gage 

heights to these rating tables gives the daily discharge from which 

the monthly and yearly mean discharge are computed.

The data presented for each gaging station in the area covered by 

this report comprise a description of the station, a table giving results 

of discharge measurements, a table showing the daily discharge, and 

a table of monthly and yearly discharge and run-off.
4 SURFACE WATER SUPPLY, 1925, PART VIII

If the base data are insufficient to determine the daily discharge, 

tables giving daily gage heights and results of discharge measurements are published.

The description of the station gives, in addition to statements 

regarding location and equipment, information in regard to any 

condition that may affect the permanence of the stage-discharge 

relation, covering such subjects as the occurrence of ice, the use of 

the stream for log driving, shifting of channel, and the cause and 

effect of backwater. It gives also information as to diversions that 

decrease the flow at the gage, artificial regulation, maximum and 

minimum recorded stages, and the accuracy of the records.

The table of daily discharge gives the discharge in second-feet 

corresponding to the mean of the gage heights read each day. At 

stations on streams subject to sudden or rapid diurnal fluctuation 

the discharge obtained from the rating table and the mean daily 

gage heights may not be the true mean discharge for the day. If 

such stations are equipped with water-stage recorders, the mean 

daily discharge may be obtained by averaging discharge for parts of 

the day or by use of the discharge integrator, an instrument operating 

on the principle of the planimeter and containing as an essential 

element the rating curve of the station.

In the table of monthly discharge the column headed "Maximum" 

gives the mean flow for the day when the mean gage height was 

highest. As the gage height is the mean for the day, it does not 

indicate correctly the stage when the water surface was at crest 

height, and the corresponding discharge was consequently larger 

than that given in the column. Likewise, in the column headed 

"Minimum," the quantity given is the mean flow for the day when 

the mean gage height was lowest. The column headed "Mean" 

gives the average flow in cubic feet for each second during the month. 

On this average flow computations recorded in the remaining columns 

which are defined on page 2 are based.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends, primarily, (1) on the 

permanence of the stage-discharge relation and (2) on the accuracy 

of observations of stage, measurements of flow, and interpretation of 

records.

A paragraph in the description of the station gives information 

regarding the (1) permanence of the stage-discharge relation, (2) precision with which the discharge rating curve is defined, (3) refinement 

of gage readings, (4) frequency of gage readings, and (5) methods of 

applying daily gage heights to the rating table to obtain the daily 

discharge.
PUBLICATIONS ' 5

For the rating curves "well defined" indicates, in general, that the 

rating is probably accurate within 5 per cent; "fairly well defined," 

within 10 per cent;" poorly defined," within 15 to 25 per cent. These 

notes are very general and are based on the plotting of the individual 

measurements with reference to the mean rating curve.

The monthly means for any station may represent with high 

accuracy the quantity of water flowing past the gage, but the figures 

showing discharge per square mile and run-off in inches may 

be subject to gross errors, caused by including large noncontributing districts in the measured drainage area, by lack of information concerning water diverted for irrigation or other use, or by 

inability to interpret the effect of artificial regulation of the flow of 

the river above the station. "Second-feet per square mile" and 

"run-off in inches" are therefore not computed if such errors appear 

probable, and are also omitted for stations on streams draining areas 

in which the annual rainfall is less than 20 inches. All figures representing "second-feet per square mile" and "run-off in inches" 

previously published by the Geological Survey should be used with 

caution because of possible unknown but inherent sources of error.

Many gaging stations on streams in the irrigated sections of the 

United States are located above most of the diversions from those 

streams, and the discharge recorded does not show the water supply 

available for further development,, as prior appropriations below the 

stations must first be satisfied. To give an idea of the amount of 

prior appropriations, a paragraph on diversions is presented in each 

station description. The figures given can not be considered exact, 

but represent the best information available.

The table of monthly discharge gives only a general idea of theflow at the station and should not be used for other than preliminary 

estimates. The tables of daily discharge allow more detailed studies 

of the variation in flow. It should be borne in mind, however, that 

the observations in each succeeding year may be expected to throw 

new light on records previously published.

PUBLICATIONS

Investigation of water resources by the United States Geological 

Survey has consisted in large part of measurements of the volume of 

flow of streams and studies of the conditions affecting that flow, but 

it has comprised also investigation of such closely allied subjects as 

irrigation, water storage, water powers, underground waters, and 

quality of waters. Most of the results of these investigations have 

been published in the series of water-supply papers, but some have 

appeared in the bulletins, professional papers, annual reports, and 

monographs.

Year

NOTE. No data regarding stream flow are given in the 15th and 17th Annual Reports.

The records at most of the stations discussed in these reports 

extend over a series of years, and miscellaneous measurements at 

many points other than regular gaging stations have been made 

each year. An index of the reports containing records obtained prior 

to 1904 has been published in Water-Supply Paper 119,
8 SURFACE WATER SUPPLY, 1925, PART VIII

The following table gives, by years and drainage basins, the numbers of the papers on surface-water supply published from 1899 to 

1923. The data for any particular station will be found in the reports covering the years during which the station was maintained. 

For example, data for Machias River at Whitneyville, Maine, 1903 

to 1921, are published in Water-Supply Papers 97, 124,165, 201, 241, 

261, 281, 301, 321, 351, 381, 401, 431,451, 471, 501, and 521, which 

contain records for the New England streams from 1903 to 1921. 

Results of miscellaneous measurements are published by drainage 

basins. '

TRINITY RIVER AT DALLAS, TEX.

LOCATION. At Commerce Street viaduct in Dallas, Dallas County, 800 feet 

below Texas & Pacific Railway bridge and 5 miles below confluence of Elm 

and West Forks of Trinity River.

DRAINAGE AREA. 6,000 square miles (measured on topographic maps and base 

map of Texas).

RECORDS AVAILABLE. October 1, 1898, to December 31, 1899 (discharge, not 

determined); July 1, 1903, to December 31, 1906; and October 1, 1920, to 

September 30, 1925. United States Weather Bureau gage-height record 

available since 1903.

GAGE. Chain gage attached to downstream handrail of Commerce Street viaduct; read by C. J. Anderson.

DISCHARGE MEASUREMENTS. Made by wading, from Commerce Street viaduct, 

or from "Miller's Ferry" bridge 6 miles below gage.

CHANNEL AND CONTROL. Channel practically straight for 1,000 feet above and 

600 feet below station. Right bank composed of clay and gravel, wooded, 

and subject to overflow; left bank not subject to overflow except at extremely 

high stages. Bed composed of clay and gravel; fairly permanent. Low-water 

control is gravel and clay shoal 300 feet below gage; high-water control not 

known. A lock and dam, 13 miles below gage, will back water at station 

to a gage height of 11.65 feet when wickets are closed. This, however, rarely 

occurs.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 34.17 feet at 

7.50 a. m. May 11 (discharge, 17,700 second-feet); minimum stage, 3.95 

feet at 7.45 a. m. August 22 (discharge, 7.5 second-feet).

1898-1899; 1903-1906; 1921-1925: Maximum stage recorded, 42.35 feet 

at 5.15 a. m. April 27, 1922 (discharge, 75,100 second-feet); minimum stage, 

4.27 feet at 4 p. m. September 11, 1924 (discharge, 6.8 second-feet).

Maximum flood on record from United States Weather Bureau records, 

52.6 feet at 6 p. m. May 26, 1908 (discharge, not determined). During 

drought of 1917-1918, discharge was practically zero. Low stages not 

comparable, owing to shifting of control.

DIVERSIONS. Only known diversions are for municipal uses. No irrigation of 

importance above.

REGULATION. Low-water flow is partly regulated by municipal dams on West 

Fork, 40 miles above, and on Elm Fork gage 6 miles above gage.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined. 

Gage read to hundredths twice daily. Daily discharge determined by applying mean daily gage height to rating table. Records good except for extremely 

low stages for which they are fair.

The following discharge measurements were made:

March 10, 1925: Gage height, 4.67 feet; discharge, 34.3 second-feet.

August 6, 1925: Gage height, 4.36 feet; discharge, 13.2 second-feet.

GAGE. Au continuous water-stage recorder attached to downstream side of 

left pier of Texas & Pacific Railway bridge. Prior to June 22 staff gage on 

right bank, 250 feet upstream from present location and set to different 

datum was used.

DISCHARGE MEASUREMENTS. Made from highway bridge, from railroad bridge, 

or by wading.

CHANNEL AND CONTROL. Channel straight for 300 feet above and below highway 

bridge. Bed at highway bridge composed of silt and is fairly permanent; 

bed at railroad bridge composed mostly of rock. Banks covered with small 

amount of brush, subject to overflow at extremely high stages. Control for 

all but extremely high stages is concrete dam 750 feet below gage; permanent. Railroad embankment below will probably be control for high stages.

LOCATION. At Grand Prairie-Duncanville highway bridge, 3^ miles southeast 

of Grand Prairie, Dallas County, and 5^ miles above confluence with West 

Fork of Trinity River.

DRAINAGE AREA. 267 square miles (measured on topographic maps and base 

map of Texas).

RECORDS AVAILABLE. March 5 to September 30, 1925.

GAGE. Stevens continuous water-stage recorder at upstream side of bridge on 

left bank; inspected by Geological Survey engineers.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

 CHANNEL AND CONTROL. Channel straight f,or 100 feet above and below gage. 

Bed of silt. Banks of earth; covered with timber; probably shifts; subject 

to overflow at high stages. One channel at low and intermediate stages 

and several at high stages. Levee 20 feet high 400 feet to right of bridge. 

Low-water control is mud bar three-fourths of a mile below gage; fairly 

permanent; high-stage control is stretch of creek and timber on banks.

EXTREMES OF DISCHARGE. Maximum stage during period from water-stage 

recorder, 17.83 feet at 6 p. m. May 9 (discharge, about 3,300 second-feet); 

no flow March 5 to April 26, May 26 to September 12, and September 22-23.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Rating curve fairly well 

defined below 200 secoud-feet and poorly defined between 200 and 3,000 

second-feet. Operation of water-stage recorder satisfactory. Daily discharge 

determined by applying to rating table mean daily gage height obtained 

from recorder graph, averaging discharge for intervals of a day on days of 

considerable fluctuation, except at extremely low stages when shifting-control 

method was used. Records poor.

road, 1 mile below confluence with Denton Creek, and 1^ miles west of

Carrollton, Dallas County. 

DRAINAGE AREA. 2,540 square miles (measured on topographic maps and base

map of Texas).

RECORDS AVAILABLE. November 1, 1923, to September 30, 1925. 

GAGE. Vertical staffs attached to left wing wall of dam and to second pile

bent from left concrete pier of bridge; read by J. L. Coleman. 

DISCHARGE MEASUREMENTS. Made from highway bridge, by wading, from boat,.

or from St. Louis Southwestern Railway bridge, 1 mile below. 

CHANNEL AND CONTROL. Channel straight for 150 feet above and below gage.

Bed and banks are of loam and clean up to a stage of 5 feet, where there are

trees and brush on banks. Left bank is subject to overflow for 1 mile at a

stage of 8 feet. Control is a concrete dam up to a stage of about 8 feet;

permanent. Valves pass water through dam at extremely low stages. 

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 7.80 feet in

morning May 10 (discharge, 12,200 second-feet); no flow October 7-11,.

October 25 to November 20, January 27 to April 24, June 19 to August 13,,

and August 31, to September 16. (See "Accuracy.")

1924-25: Maximum stage recorded, 12.75 feet during morning of December

14, 1923 (discharge not determined); no flow during several periods. 

DIVERSIONS. None. 

REGULATION. Low flow completely regulated by Garza Dam, 20 miles above,.

and flow at high stages partly regulated by same. 

ACCURACY. Stage-discharge relation permanent. Rating curve well defined

below 2,000 second-feet and poorly denned above. Discharge represents

flow over dam only. Prior to August 9, during extremely low stages, valves.

in dam were leaking a small amount. Valves in dam were open from

March 9 to April 24 and from September 1-15. Gage read to hundredthstwice daily. Daily discharge determined by applying mean daily gage height

to rating table. Records fair.

The following discharge measurements were made:

January 14, 1925: Gage height, 0.17 foot; discharge, 4.29 second-feet.

August 8, 1925: Discharge, 0 second-foot.

ELM FORK OF TRINITY RIVER NEAR DALLAS, TEX.

LOCATION. At city of Dallas pumping plant and dam (known as Record Crossing 

plant), 2,800 feet above Rock Island Railroad bridge, 1.2 miles above confluence with West Fork, and 5 miles northwest of Dallas, Dallas County.

DRAINAGE AREA. 2,660 square miles (measured on topographic maps and base 

map of Texas).

RECORDS AVAILABLE. October 17, 1920, to September 30, 1925.

GAGE. Vertical staff attached to pump house; read by W. J. Selby.

DISCHARGE MEASUREMENTS. -Made from Record Crossing highway bridge, 200- 

feet below gage, from Rock Island Railroad bridge half a mile below or by 

wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel; shifting. Control 

is concrete dam; permanent. Left bank is wooded and not subject to over-* 

flow, except at extremely high stages; right bank wooded and subject to 

overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 16.0 feet at, 

4 p. m. May 10 (discharge not determined on account of backwater); no 

flow during several periods.

1920-1925: Maximum stage recorded, 20.20 feet at 10 a. m. April 27, 1922. 

(discharge not determined; backwater from Trinity River existed this day 

which affected gage height); no flow during several periods.
58 SURFACE WATER SUPPLY, 1925, PART VIII

DIVERSIONS. No diversions except for municipal use, the largest being at Record 

Crossing plant. The sum of all diversions is believed to be but a small percentage of the total run-off during years of ordinary flow.

REGULATION. Flow partly regulated by reservoir of city of Dallas at Carrollton, 

and Garza Dam above Carrollton.

ACCURACY. Stage-discharge relation probably permanent except during backwater periods. Rating curve well defined below 1,100 second-feet, poorly 

defined between 1,100 and 6,200 second-feet, and fairly well defined above. 

Gage read to hundredths twice daily and oftener during floods. Daily discharge determined by applying mean daily gage height to rating table, averaging discharge for intervals of a day on days of considerable fluctuation, 

except as noted in footnote to daily-discharge table. Records fair.

Station visited by Geological Survey engineers January 15, August 6, and September 4; no flow on these days.

DRAINAGE AREA. 760 square miles (measured on topographic maps, base map 

of Texas, and progressive military maps of United States Army).

RECORDS AVAILABLE. December 11, 1924, to February 11, 1925, when station 

was discontinued. **

GAGE. Chain gage attached to downstream guardrail of railroad bridge; read 

by Eddie Tigert.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Bed composed of silt; shifts. Channel straight above 

and curved below gage. Banks composed of silt; shift and subject to 

overflow. Control for low stages is mud bar just below gage; at medium 

stage control probably is dam 1 mile below gage; high-stage control indefinite.

DIVERSIONS. None of consequence.

RE GUL ATI ON . None.

ACCURACY. No rating curve developed. Gage read to hundredths twice daily. 

Discharge was estimated from two measurements, daily gage readings, 

and study of rainfall as follows: December 11-31, 20.8 acre-feet; January 

1-31, 30.7 acre-feet; February 1-11, 10.9 acre-feet.

The following discharge measurements were made:

December 11, 1924: Gage height, 1.67 feet; discharge, 0.40 second-foot.

January 29, 1925: Gage height, 1.19 feet; discharge, 0.48 second-foot.

RECORDS AVAILABLE. September 14, 1898, to December 31, 1011, and October 

1, 1914, to September 30, 1925. Record of stage has been obtained by 

United States Weather Bureau since August 9, 1900.

GAGE. Stevens continuous water-stage recorder attached to downstream side 

of Texas Electric Co.'s bridge. From May 6, 1922, to February 12, 1925, 

United States Weather Bureau gage on suspension bridge 100 feet downstream was used. Gages were installed at same datum but readings probably differ slightly because of difference in location.

DISCHARGE MEASUREMENTS. Made from first one-span highway bridge above 

gage or by wading.

CHANNEL AND CONTROL. Bed of sand and gravel; shifts. Banks are clay; 

subject to overflow at extremely high stages. Channel straight above and 

below for several thousand feet. Position of control not known.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage 

recorder, 21.1 feet at 8 a. m. May 9 (discharge, 55,200 second-feet); minimum discharge, about 24 second-feet March 27-30.

1898-1925: Maximum stage recorded, 39.7 feet December 3, 1913 (discharge not determined); no flow August 20-21, 1918, and probably several 

days in August, 1923.

DIVERSIONS. Records of the Board of Water Engineers for the State of Texas 

show that numerous small diversions are made above station for mining, 

irrigation, and municipal uses, but total probably does not appreciably 

affect flow except during low stages.

RE a UL ATI ON . None.

ACCURACY. Stage-discharge relation not permanent. Rating curve fairly 

well defined above 40 second-feet. Gage read to tenths once daily prior to 

February 12; operation of water-stage recorder satisfactory thereafter. 

Daily discharge determined by shifting-control method, averaging discharge 

for fractional parts of a day on days of considerable fluctuation, except as 

noted in footnote to daily-discharge table. Records October 1 to February 

12, poor; fair thereafter.

COOPERATION. Gage-height record from October 1 to February 12 furnished 

by United States Weather Bureau.

CLEAR FORK OF BRAZOS RIVER AT FORT GRIFFIN, TEX.

LOCATION. At highway bridge on Fort Griffin-Throckmorton road, 600 feet 

below mouth of Collins Creek and half a mile east of Fort Griffin, Shackleford County.

DRAINAGE ABEA. 3,970 square miles (measured on topographic maps and 

base map of Texas). *

RECORDS AVAILABLE. December 9, 1923, to September 30, 1925.

GAGE. Chain gage attached to downstream side of bridge; read by H. C. 

Herron.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNKL AND CONTROL. Channel straight for 200 feet above and 400 feet 

below gage. Bed composed of gravel; permanent. Banks of clay, underlain by a stratum of rock; sparsely wooded; fairly permanent. Left bank 

subject to overflow at a stage of 15 feet; right bank at a stage of 33 feet. 

At extremely high stages, bridge cannot be reached except by boat. Lowwater control is gravel shoal, 300 feet below gage; fairly permanent. Highwater control is probably channel and banks some distance below station.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 18.35 feet 

at 6.30 p. m. May 11 (discharge, 6,820 second-feet); minimum stage, 1.84 

leet at 6 p. m. April 8 (no flow; this is also point of zero flow).

1924-1925: Maximum and minimum stages same as those for 1925.

DIVERSIONS. Small amount diverted for municipal use. Amount not known.

REGULATION. Possibly slight regulatory effect at low stages by power plant 

at Stamford.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined. 

Gage read to hundredths twice daily. Daily discharge determined by 

applying mean daily gage height to rating table. Records fair.

CLEAR FORE OF BRAZOS RIVER NEAR ELIASVHLE, TEX.

LOCATION. At suspension highway bridge near southern Mne of Young County. 

2^4 miles northeast of Eliasville, 6 miles above mouth of stream.

DBAINAGE AREA. 5,740 square miles, revised (measured on topographic maps 

and base map of Texas).

RECORDS AVAILABLE. November 12, 1915, to April 30, 1920; December 8, 1923, 

to August 31, 1925, when station was discontinued.

GAGE. Chain gage attached to downstream handrail of bridge; staff gage at bridge 

from March 26 to August 31. Gages read by Fred Brooks.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed of sand and gravel; free from vegetation. Channel straight above and below station. One channel at all stages. Banks 

are wooded, composed of clay and sand, and are subject to overflow at a 

stage of 38 feet. Below 2-foot stage the control is gravel shoal, 800 feet below 

gage, and from 2 feet to 8 feet, it is a shoal 600 feet below gage. High-stage 

control not known. Both low-water controls subject to.shift. There is a 

possibility of backwater from Brazos River during high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during period, 22.0 feet 

at noon May 7 (discharge, 11,600 second-feet); no flow November 27, 28, 

March 7, 14, 24, April 4-9.

1916-1920; 1923-1925: Maximum stage recorded, 24.3 feet at 5 p. m. 

September 21, 1924 (discharge, 13,600 second-feet); no flow for extended 

periods.

DIVERSIONS. Records of Board of Water Engineers for the State of Texas show 

numerous small diversions above station which probably reduce flow conv siderably at low stages. Two diversions are made between station and confluence with Brazos River.

REGULATION. None of consequence except at extremely low stages.

ACCURACY. Stage-discharge relation not permanent. Rating curve well defined. 

Gage read to half-tenths twice daily from October 1 to March 25, but work 

of the observer not reliable. Gage read to hundredths twice daily thereafter. Daily discharge determined by shifting-control method or by comparison with flow at other stations, but daily-discharge records not sufficiently accurate for publication. Monthly records fair.

JJTTIE KIVEB HEAR LITHE RIVER, TEX^

LOCATION. At Missouri, Kansas & Texas Railway bridge, 150 feet west of 

Bartlett-Temple highway, 2 miles south of Little River, Bell County, and 

4J^ miles below confluence of Leon and Lampasas Rivers.

DRAINAGE AREA. 5,250 square miles (measured on topographic maps and base 

map of Texas).

RECORDS AVAILABLE. October §, 1923, to September 30, 1925.

GAGE. Chain gage attached to downstream,1 guardrail of middle span of railway 

bridge; read by A. J. Lanham.

DISCHAEGE MEASUREMENTS. Made from downstream side of railway bridge, 

from highway bridge, or by wading.
94 SURFACE WATER SUPPLY, 1925, PART VIII

CHANNEL AND CONTROL. Bed composed of mud and silt, overlying decomposed 

rock; shifts. Banks covered with brush and light timber; subject to overflow. 

Channel straight for 250 feet above and 150 feet below gage. Control is 

a small brushy island, 150 feet below gage, which divides the stream at low 

stages into two channels; shifts. This island is submerged at high1 stages, when 

the control is probably a stretch of the channel below the island and a riffle 

at the highway bridge. Trees and brush on banks and on island probably 

serve as incomplete control at intermediate and high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 22.2 feet at 7 

p. m. September 12 (discharge, 5,140 second-feet); minimum stage, 3.26 

feet at 2.50 p. m. August 12 (discharge, 8.9 second-feet).

1924-25: Maximum stage recorded, 37.0 feet at 8 a. m. December 13, 1923 

(discharge, 14,800 second-feet); minimum stage, that of August 12, 1925.

DIVERSIONS. Several small diversions above station; amount diverted not known.

REGULATION. Dam of Temple waterworks on Leon River may regulate flow at 

extremely low stages.

ACCURACY. Stage-discharge relation not permanent. Rating curve fairly well 

defined. Gage read to hundredths twice daily and oftener during floods. 

Daily discharge determined by shifting-control method. Records fair.

LITTLE RIVER AT CAMERON, TEX.

LOCATION. At McCowan Bridge, at Cameron-Rockdale highway crossing, 1 

mile above Gulf, Colorado & Santa Fe Railway bridge, 2 miles southeast 

of Cameron, and 6J^ miles below mouth of San Gabriel River,

DRAINAGE AREA. 7,030 square miles (measured on topographic maps, base map 

of Texas, and progressive military map of United States Army).

RECORDS AVAILABLE. November 1, 1916, to September 30, 1925.

GAGE. Chain gage attached to upstream handrail of bridge; read by Tracy 

Hobson.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of rock, boulders, sand, gravel, and 

clay; fairly permanent. Right bank of rock; subject to overflow at extremely 

high stages. Left bank of clay and gravel; slightly wooded; water flows 

through a draw at a stage of 27 feet and over road at a stage of 31.5 feet, 

A rough rock and gravel shoal 20 feet below gage serves as control for low 

and medium stages; may shift. During extremely high stages on Brazos 

River backwater may reach gage.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 14.2 feet in 

morning of September 14 (discharge, 4,290 second-feet); minimum stage, 

2.40 feet at 7.20 p. m. July 30 (discharge, 10 second-feet).

1917-1925: Maximum stage recorded, 49.5 feet at 2.30 p. m. September 

10, 1921 (discharge, 647,000 second-feet, determined by slope method, using 

value of 0.035 for "n" in Kutter's formula). Minimum discharge, 2.6 

second-feet at 7 a. m. September 3, 5, and 7, 1918.

DIVERSIONS. Numerous small diversions are made for irrigation and municipal 

uses, but such diversions have little effect on flow at station, except during 

extremely low stages. Records of the Board of Water Engineers for the 

State of Texas show that about 2,500 acres have been declared irrigated 

above station. No divers-ions of consequence below station. During time 

of low flow, water pumped by Cameron Power & Light Co. will affect flow 

at this station.

REGULATION. Slight effect by pumping for city of Cameron.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve 

well defined. Gage read to hundredths twice daily. Daily discharge determined by applying mean daily gage height to rating table, except as noted 

in footnote to daily-discharge table. Records good.

COLORADO RIVER BASIN 

COLORADO BITER AT COLORADO, TEX.

LOCATION. At lower steel highway bridge at Colorado, Mitchell County, 1*4 

miles below Texas & Pacific Railway bridge.

DRAINAGE AREA. 4,280 square miles, a large part of which is probably noncontributing (measured on base map of Texas).

RECORDS AVAILABLE. November 28, 1923, to August 31, 1925, when station 

was discontinued.

GAGE. Chain gage attached to upstream side of highway bridge; read by 

Paul Snively.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading. ,

CHANNEL AND CONTROL. Channel straight for half a mile above and below 

gage. Bed composed of sand and silt; shifts. Banks of sandy clay; covered 

with brush and light timber; subject to overflow at high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during period, 11.40 feet 

during night of April 24 (discharge, 5,180 second-feet determined from mean 

curve between two slope measurements and subject to error). No flow 

during several periods.

1924-1925: Maximum stage occurred in 1925. No flow during periods 

in 1924 and 1925.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve 

well defined below 850 second-feet and poorly defined above. Gage read to 

hundredths twice daily. Daily discharge determined by applying mean 

daily gage height to rating table, averaging discharge for intervals of a day 

on days of considerable fluctuation, or as noted in footnote to daily-discharge 

table; shifting control method used October 7 to May 8 and August 13-31. 

Records fair.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by 

wading.

CHANNEL AND CONTROL. Banks consist of clay and gravel, wooded, and 

subject to overflow at extremely high stages. Bed of hard clay, sand, 

gravel, and rock; shifting. Control is rock shoal, one-third mile below gage; 

permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 21.10 feet at 

11 a. m. April 27 (discharge, about 17,000 second-feet, determined from extension of rating curve); minimum discharge, 0.20 second-foot at 8.05 a. m. 

April 8.

1916-1925: Maximum stage recorded, 26.0 feet during night of Agril 26, 

1922 (discharge, about 28,000 second-feet, determined from extension of 

rating curve); no flow during several periods.

DIVERSIONS. During low stages, a large part of flow is diverted a few miles 

above station for irrigation. Records of the Board of Water Engineers for 

the State of Texas show that about 6,900 acres have been declared irrigated 

above station.

HEGULATION. None of consequence.

ACCURACY. Stage-discharge relation permanent. Rating curve fairly well 

defined below 1,000 second-feet and poorly defined from 1«,000 to 14,000 

second-feet and extended above. Gage read to hundredths twice daily. 

Daily discharge determined by applying mean daily gage height to rating 

table. Records for low stages good and for medium and high stages fair.

COLORADO RIVES NEAR TOW, TEX.

LOCATION. At highway bridge 1J^ miles northeast of Tow, Llano County, 2 

miles below mouth of Fall Creek and 6 miles northwest of Bluffton.

DRAINAGE AREA. 31,100 square miles, large part of which is probably noncontributing (measured on topographic maps and base map of Texas).

RECORDS AVAILABLE. October 26, 1923, to September 30, 1925.

GAGE. Au continuous water-stage recorder attached to downstream side of 

bridge pier. Prior to April 16, chain gage attached to upstream handrail 

of bridge; read by W. A. Farris.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Channel straight for 2 miles above and half a mile 

below gage. Bed of rock partly overlain with gravel and silt; fairly permanent. Banks covered with brush and light timber; subject to overflow only at 

extremely high stages. Control is rock ledge and boulder shoal, one-eighth 

mile below gage; permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 16.74 feet 

at 4 a. m. May 12 (discharge, 27,000 second-feet); minimum stage, 5.00 feet 

at 5 p. m. January 10 (discharge, 24 second-feet, determined from extension 

of rating curve and subject to slight error). 

1924-1925: Same as given above.

DIVERSIONS. Numerous small diversions in drainage basin above; amount not 

known.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined 

above 75 second-feet. Gage read to hundredths twice daily from October 1 

to April 16. Operation of water-stage recorder satisfactory thereafter. 

Daily discharge determined by applying to rating table mean daily gage 

height or for days of considerable fluctuation by averaging discharge for 

intervals of a day. Records good.

COLORADO RIVER BASIN 117 

COLORADO RIVER AT MARBLE FALLS, TEX.

LOCATION. At steel highway bridge, one-fourth mile south of Marble Falls, 

Burnet County, and 10 miles below mouth of Sandy Creek.

DRAINAGE AREA. 36,100 square miles, a part of which is probably noncontributing (measured on topographic maps and base map of Texas).

HECORDS AVAILABLE. October 1, 1916, to September 30, 1925. Miscellaneous 

discharge measurements were made in 1902. Records of stage have been 

obtained by United States Weather Bureau since January 1, 1908.

GAGE. Chain gage on upstream side of bridge; read by N. C. Galloway.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

 CHANNEL AND CONTROL. Bed composed of solid rock. Banks of rock, gravel, 

and clay; wooded and not subject to overflow. Rapids just below gage 

serve as fairly permanent control, except at times when sand and gravel 

collect.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 12.28 feet at 

6.25 p. m. May 30 (discharge not determined); minimum stage, 0.74 foot at 

6.40 p. m. July 30 (discharge, 74 second-feet; subject to error, owing to influence of wind on tape.

1900-1925: Maximum stage,1 23.9 feet April 7, 1900 (discharge, not determined) ; no flow August 7, 8, 11, and 25, 1918, caused by storing water above

DIVERSIONS. Several large projects have been proposed in drainage basin above 

station but none have been developed. Numerous small diversions for 

irrigation and municipal uses are made above station. Total amount diverted 

not known. Records of the Board of Water Engineers for the State of Texas 

show that approximately 36,000 acres have been declared irrigated by diversions above station. Little water is diverted between Marble Falls and' 

Austin.

REGULATION. None of importance, except possibly during extremely low stages.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined 

below 6,000 second-feet and poorly defined above, owing to the inability to 

read gage accurately on account of surge and inaccuracies in measurements 

due to high velocities and submerged drift. Gage read to hundredths twice 

daily, although influence of wind on long gage chain and surge of water at 

high stages probably introduce some error. Daily discharge above 6,000 

second-feet not of sufficient accuracy for publication. Daily discharge for 

periods published determined by applying mean daily gage height to rating 

table. Records for low stages fair and for intermediate stages poor.

The following discharge measurements were made:

January 9, 1925: Gage height, 1.85 feet; discharge, 367 second-feet.

April 20, 1925: Gage height, 1.26 feet; discharge, 172 second-feet.

COLORADO RIVER AT AUSTIN, TEX.

LOCATION. At Congress Avenue concrete viaduct in Austin, Travis County, 

half a mile below mouth of Shoal Creek, above mouth of Waller Creek, 

and 3J^ miles below Austin Dam.

DRAINAGE AKEA. 38,200 square miles, part of which is probably noncontributing (measured on topographic maps and base map of Texas).
COLORADO RIVER BASIN 119

RECORDS AVAILABLE. February 15, 1898, to September 30, 1925. Records of 

stage have been obtained by United States Weather Bureau since July 1, 

1903.

GAGE. Au 60-day water-stage recorder on downstream side of pier of viaduct; 

inspected by engineers of United States Geological Survey.

DISCHARGE MEASUREMENTS. Made by wading or from upstream side of 

Montopolis highway bridge, 4 miles below gage.

CHANNEL AND CONTROL. Channel straight for 1,000 feet above and 500 feet 

below gage. Right bank composed of clay and gravel and subject to overflow; left bank resembles right bank, except that it is not subject to overflow. 

Bed composed of rock, gravel, and sand; shifts. Control is gravel shoal 

500 feet below gage; shifts.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage recorder, 9.30 feet at 7.55 a. m. May 31 (discharge, 32,000 second-feet); minimum stage, 0.11 foot from 7 a. m. to 5 p. m. August 1 and from 8 p. m. 

August 1 to 6 a. m. August 2 (discharge, 88 second-feet).

1898-1925: Maximum stage recorded, 33.5 feet a few minutes after 

failure of dam which occurred at 11.30 a. m. April 7, 1900 (discharge, 236,000 

second-feet, determined from extension of rating curve and subject to considerable error). At the time of failure the depth of water over crest of 

dam was 11.07 feet, with a computed discharge of 151,000 second-feet. 

According to information obtained from people living near Congress Avenue 

Bridge, water rose 6.1 feet as a result of failure. Therefore, the gage height 

corresponding to a discharge of 151,000 second-feet was 27.4 feet. According to a statement by Mr. W. P. Johnson, who was in charge of power plant 

at dam, the flood appeared to be practically at its crest when the dam failed. 

Minimum discharge, 13 second-feet at 6 p. m. August 18, 1918.

DIVERSIONS. Records of the Board of Water Engineers for the State of Texas 

show that approximately 36,000 acres of land have been declared irrigated 

by diversions above the station. Most of the area irrigated is in the upper 

basin of the main stream and adjacent to large tributaries. Little water 

is diverted between Austin and Columbus.

REGULATION. Flow entirely regulated at times by operation at Austin Dam, 

about 33^} miles upstream. Sluice gates, crest gates, and power plant at 

the dam were not in operation during the years ending September 30, 

1919-1925. Capacity of reservoir about 24,000 acre-feet.

ACCURACY. Stage-discharge relation not permanent. Standard rating curves 

well defined. Operation of water-stage recorder satisfactory, except as 

noted in footnote to daily-discharge table. Daily discharge determined by 

shifting-control method, averaging discharge for intervals of a day on days 

of considerable fluctuation. Records good.

bank subject to overflow above a gage height of 34 feet. Bed of sand; shifts. 

A sand and gravel section 350 feet below gage may serve as low-water 

control. Stage-discharge relation during medium and high stages may be 

controlled by a bend in river below bridge.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage 

recorder, 19.64 feet at 8 a. m. May 14 (discharge, 21,100 second-feet); 

minimum discharge, 123 seeond-feet at 7.30 a. m. August 8.

1902-1911; 1916-1925: Maximum stage recorded, 38.3 feet May 5, 1922 

(discharge, 79,500 second-feet, determined from extension of rating curve 

and subject to error); minimum discharge, 10 second-feet September 9 

and 10, 1910.
122 SURFACE WATER SUPPLY, 1925, PAHS' VIII

DIVEESIONS. Considerable water is diverted for irrigation in drainage basin 

above Austin, but between Austin and Columbus, little water is diverted. 

The station is above the irrigated rice belt which comprises several thousand 

acres. Records for the Board of Water Engineers for the State of Texas 

show that about 36,000 acres have been declared irrigated above Austin.

REGULATION. Flow at Columbus during low stages partly controlled by storage 

at Lake Austin.

ACCURACY. Stage-discharge relation not permanent. Rating curve well defined. 

Operation of water-stage recorder not satisfactory owing to improper 

attendance. Daily discharge determined by shifting-control method, averaging discharge for intervals of a day, on days of considerable fluctuation. 

Records fair.

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

COLORADO RIVER AT WHART0W. TEX.

LOCATION. At highway bridge in western edge of Wharton, Wharton County, 

200 feet below Galveston, Harrisburg & San Antonio Railway bridge.

DRAINAGE AREA. 41,200 square miles, a large part of which is probably noncontributing (measured on topographic maps, base map of Texas/ and progressive military map of United States Army).

RECORDS AVAILABLE. July 12 to August 31, 1916; July 3 to August 18, 1917; 

July 11 to August 4, 1918; and April 19, 1919, to September 30, 1925, when 

station was discontinued.

GAGE. Gurley graph water-stage recorder attached to pier of highway bridge 

near left bank, inspected by A. F. Kaiser.

DISCHARGE MEASUREMENTS. Made from highway bridge, from railway bridge, 

or by wading.

CHANNEL AND CONTROL. Channel straight above and below station for a few 

hundred feet. Bed composed of sand and clay; subject to shift. Banks 

composed of clay; subject to overflow during extremely high stages. At a 

gage height of 34 feet, water enters a channel above station known as Caney 

Creek and flows thence to Gulf of Mexico. The Colorado River raft, several 

miles below station, probably serves as control for all but extremely low

EXTREMES OF DISCHARGE. Maximum stage from water-stage recorder, 22.35 

feet at 11 a. m. May 15 (discharge, 22,100 second-feet); no flow at 7 p. m. 

August 6 (determined from poor gage-height record and poorly-defined curve 

and subject to considerable error).

1916-1925: Maximum stage recorded, 40.7 feet from 9 a. m. to 6 p. m. 

May 6, 1922 (discharge not determined); no flow August 6, 1925.

DIVERSIONS/ Station is in area of rice irrigation, roughly estimated to cover 

about 75,000 acres, about one-third of which is irrigated by diversions from 

Colorado River between Columbus and Wharton, and the remaining twothirds by diversions below Wharton. During periods of maximum demands, 

practically the entire flow is diverted, unless the river is above ordinary* 

stage.

RfcGtrLAf KJN. Flow at low and medium stages is regulated to soaw exteflt by 

storage in Lake Austin at Austin.

17686 29 9
124 SURFACE WATER SUPPLY, 1925, PART VIII

ACCTJKACY. Stage-discharge relation permanent. Rating curve well defined 

above 40 second-feet. Operation of water-stage recorder satisfactory except 

for short breaks in record. Record August 1-11 subject to error on account 

of poor gage-height record. Daily discharge determined by applying to 

rating table mean daily gage height obtained from recorder graph by inspection or by use of planimeter, averaging discharge for intervals of a day on 

days of considerable.fluctuation. Records prior to August 1 fair; poor thereafter.

gage congested with brush and debris and fairly clear below. One channel 

at all «&ig«s. Banks covered with light timber and brush; jpibjeet to overflow. Channel winding above gage and straight for 1,000 feet below. Low 

and medium stage control formed by rock shoal 700 feet below gage. Brush 

located in channel below control may act as incomplete control when shoals 

are submerged. High-stage control indefinite.

EXTREMES OF DISCHARGE. -Maximum stage recorded during period, 15.5 feet 

during morning April 24 (discharge, 5,180 second-feet, determined by slope 

method and subject to considerable error) ; no flow during several periods, 

1924-25: Same as given above.

COLOEADO EIVEE BASIN 129

NOETH CONCHO RIVER NEAR CARLSBAD, TEX.

LOCATION. Just above State Sanitorium Dam, 1% miles below mouth of Live 

Oak Creek and 2 miles above Carlsbad, Tom Green County.

DRAINAGE AREA. 1,530 square miles (measured on base map of Texas).

RECORDS AVAILABLE. March 27, 1924, to September 30, 1925.

GAGE. Stevens continuous water-stage recorder attached to left side of dam; 

inspected by Geological Survey engineers. Prior to February 4, 1925, 

vertical staff; on- Ufa btok' near^State pump station, just above dam; read 

by T. E. Heskew.

DISCHARGE MEASUREMENTS. Made from cable 200 feet above gage or by wading.

CHANNEL AND CONTROL. Bed composed of rock, overlain in places with gravel 

and silt with large pecan trees along edge of stream. Channel straight for 

600 feet above and 400 feet below gage. Banks covered with brush and 

trees, and subject to overflow at extremely high stages. At about gage 

height of 12.5 feet and discharge of 25,000 second-feet, water runs over 

crest of banks on both sides of stream into draws which do not drain back 

into river but form lakes. Control is concrete dam just below gage; permanent. There is a notch iii crest of dam as a part of a fish ladder, and 

during very dry periods this notch is closed. Point of zero flow with notch 

open, 1.67 feet; with notch closed, 2.21 feet.

EXTREMES of DISCHARGE. Maximum stage during year from water-stage 

recorder, 14.45 feet at 1.10 p. m. May 30 (discharge, 35,600 second-feet, 

determined from extension of rating curve and subject to considerable 

error); no flow April 21-22.

1924-25: Maximum stage that of May 30, 1925; no flow during several 

periods.

DIVERSIONS. Several pumps in the drainage above which are reported to have 

a combined capacity of 40 second-feet; amount of water actually diverted 

not known, but flow materially affected at low stages.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent. Rating curve fairly well 

defined below 3,000 second-feet and extended through- one discharge measurement made by slope method. Gage read to hundredths once daily 

January 1 to February 3, btlt work of observer net satisfactory. Operation of 

water-stage recorder satisfactory February 4 to September 30. Daily 

discharge determined by applying mean daily gage height to rating table, 

averaging discharge for intervals of a day on days of considerable fluctuation, except as noted in footnote to daily-discharge table. Records 

prior to February 3, poor; fair thereafter.

COirCHO BIVS31 AT SAW ANCffllO, T1X.

LOCATION. At county concrete viaduct in San Angelo, Tom Green County, 1

mile above confluence with South Concho River. 

DRAINAGE AREA. 1,806 square miles (measured on topographic maps and

base map of Texas).

RSCORBB AVMLABtE. ^-October 27, 1$15, to Septembet 30-, 1925. 

GrAGte. StevSns continuous y!%te,r-;stage recorder attached to left side of web

of 'third pier of viaduct from left bank; inspected by Geological Survey

DISCHARGE <JlEA&tiREM8NTs. Made from second highway bridge up'stfeaaa 

from gage or by wttding.

CHANNEL AND CONTROL. Bed composed of solid rock which is to some extent, 

covered in high-water channel with grass and motes; permanent, Channel 

straight for 800 feet above and 400 feet below gage. Banks of rock and 

clay; subject to overflow during high floods. About 20 feet below gage 

and at downstream side of viaduct is a concrete dam, about 4^! feet high, 

which before the Viaduct was constructed served as part of low-water 

crossing. This dam forms an artificial control and insures a permanent 

stage-discharge relation. Portion of this dam removed temporarily September 10-30. Backwater probably occurs at this station when Ooncho 

River reaches a stage of 25 feet.

EXTREMES OF DISCHARGE. Maximum stage from water-stage recorder, 18.70 

feet at 11.30 p. m. May 30 (discharge not determined); no flow during 

several periods.

1916-1925: Maximum stage recorded, 19.3 feet at 7.30 p. m. April 26, 

1922 (discharge not determined; backwater from Concho River probably 

existed); no flow for several periods.

DivBRSiON&.-^-Reeords of the Board of Water Engineers for the State of Texas 

show that about 600. acres have been declared irrigated by diversions from 

North Concho River, all above station.

REGULATION. None of consequence.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined 

below 1,100 second-feet, poorly defined between 1,100 and 14,000 secondfeet, and extended above. Operation of water-stage recorder satisfactory 

' Until September 10, when part of control dam was removed. Daily discharge determined by applying to rating table mean daily gage height 

obtained from recorder graph by inspection, averaging discharge for intervals 

of a day on days of considerable fluctuation. Records fair.

CONCHO RIVER NEAR SAN ANGEIO, TEX.

LOCATION. Half a mile below confluence of North Concho and South Concho 

Rivers, 1% miles southeast of San Angelo, Tom Green County.

DRAINAGE AREA. 4,490 square miles (measured on topographic maps and base 

map of Texas).

RECORDS AVAILABLE. September 17, 1915, to September 30, 1925. '

GAGE. Stevens continuous water-stage recorder on right bank, 1,500 feet below 

an old ford; inspected by Geological Survey engineers.

DISCHARGE MEASUREMENTS. Made by wading or from cable 1,500 feet above 

gage.

CHANNEL AND CONTROL. Bed of solid rock and gravel. Channel straight for 

1,000 feet above and below station. Right bank wooded, rocky, and 

not subject to overflow. Left bank of clay and gravel, covered with scattered trees, and subject to overflow at high stages. Rapids just below gage 

serve as control for medium and low stages, but affected by moss; position 

of control for high stages not known.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage 

recorder, 31.2 feet at 2.30 a. m. May 31 (discharge, 78,400 second-feet, 

determined from extension of rating curve and subject to error); minimum 

stage, 0.46 foot from 11 a. m. July 26 to 3 a. m. July 29 (discharge, 2.0 

second-feet).

1915-1925: Maximum stage recorded, 36.8 feet April 26, 1922 (discharge, 

139,000 second-feet, determined from extension of rating curve and subject 

to considerable error); no flow November 29, 1921.

DIVERSIONS. Flow at low stage materially affected by diversions above station. 

About a mile above mouth of South Concho River there is a storage dam. 

Records of the- Board of Water Engineers for the State of Texas show that 

about 11,000 acres have been declared irrigated by water diverted above 

the station, and about 3,500 acres by diversions below station.

REGULATION. Storage at dam 1 mile above mouth of South Concho River has 

slight effect on flow at station. No regulation of consequence on North 

Concho River.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined 

below 1,000 second-feet, fairly well defined from 1,000 to 22,000 secondfeet, and poorly defined from 22,000 to 44,000 second-feet. Operation of 

water-stage recorder satisfactory. Daily discharge determined by applying 

to rating table mean daily gage height ascertained from recorder graph by 

inspection or by use of planimeter, averaging discharge for intervals of a 

day on days of considerable fluctuation. Records for low stages, good; 

for high stages, fair.

COITCHO RIVER NEAR PAINT BOCK, TEX.

LOCATION: -At Concho, San Saba & Llano Valley Railroad bridge, a quarter of 

a mile below mouth of Kickapoa Creek, 1H miles above highway bridge, and 

2 miles northwest of Paint Rock, Concho County.

DRAINAGE AREA. 5,530 square miles (measured on topographic maps and base 

map of Texas),

RECORDS AVAILABLE. September 20, 1915, to September 30, 1925.
COLORADO RIVES BASIN 135

GAGE. Stevene continuous water-stage recorder attached to dowiastream end of 

middle railroad bridge pier; inspected by engineers of Geological Survey.

DISCHARGE MEASUREMENTS. Made by wading, from railroad bridge, or from 

highway feridge below.

CHANNEL AND CONTROL. Bed composed of solid rock; smooth and permanent. 

Channel straight for 500 feet above and below gage. Right b»nk is of solid 

rock and not subject to overflow; left bank wooded and subject to overflow 

during high water. Permanent control during low and meeUum stages is 

a solid-rock shoal, 400 feet below gage.

EXTREMES oj DISCHARGE. Maximum stage daring year froea water-stage 

recorcTSr, 20.15 feet at 5 p. m. May 31 (discharge not determined); no flow 

April 6-8, 12, 13, and 24.

1915-1925: Maximum stage recorded, 27.5 feet at 11 a. m. April 27, 1922 

(discharge not determined); .no flow during several periods of every year«xcept 

1920 and 1921,

DIVERSIONS. Records of the Board of Water Engineers for the State of Texas 

show that about 11 $00 acres have been declared irrigated by diversions from 

Concho River, practically all of which are above station. Flow during low 

stages is materially affected by diversions.

REGULATION. Ten storage dams of small capacity are .located between this station and San Angelo. An abandoned dam 12 feet in height, known as " Fowr 

Mile Dam," is 4 miles below San Angelo, and a small dam 8 feet in height 

has been constructed for storage on Sims ranch just above station. None of 

the dams appreciably affect the flow by storing water, except dwring extremely 

low stages.

ACCURACY. Stage-discharge relation not permanent. Rating curve well defined 

below 6,000 second-feet, poorly denned between 6,000 and 19,000 secondfeet, and extended above. Operation of water-stage recorder satisfactory. 

Daily discharge determined by applying to rating table mean daily gage 

height determined from recorder graph by inspection or by use of planimeter, 

averaging discharge for intervals of a day on days of «ongideiable fluctuation; 

shifting-control method used December 4 to April 28. Records for low and 

medium stages, good; for high stages, poor.

140 SURFACE WATER SUPPLY, 1925, PART VIII 

PECAN BAYOU AT BROWNWOOD, TEX.

LOCATION. At city pumping plant of Brownwood, 800 feet above lower dam, 

three-eighths mile above Brownwood-Comanche highway bridge, 1 mile 

north of Brownwood, Brown County, and 2 miles above mouth of Adams 

Branch.

DRAINAGE AREA. 1,610 square miles (measured on topographic maps and base 

map of Texas).

RECORDS AVAILABLE. May 24, 1917, to June 30, 1918, and October 17, 1923, to 

September.30,,1925.

GAGE. Combined inclined and vertical staff gage attached to trees on right 

bank, at rear and upstream end of city pumping plant; read by C. N. Da vis.

DISCHARGE MEASUREMENTS. Made from highway bridge three-eighths mile 

below gage, from cable at gage, or by wading.

CHANNEL AND CONTROL. Bed composed of mud and clay. Channel straight 

above and below station. Banks wooded and subject to overflow during 

extremely high stages. At a stage of about 12 feet there is flow through 

sloughs to right and left which leave the bayou above gage and return below 

gage. City dam, 800 feet below gage, serves as control for stages when 

flow is confined within banks; dam has opening of 140 feet. When banks 

are submerged, water spreads over wide area and control not known.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 71.5 feet 

at 6.30 p. m. May 10 (discharge, 7,470 second-feet); no flow during several 

periods.

1917-1918; 1924-1925: Maximum stage recorded, 9.90 feet at 1 p. m. 

May 14, 1924 (discharge, 12,100 second-feet, determined from extension of 

rating curve and subject to error); no flow for several periods.

DIVERSIONS. Records of the Board of Water Engineers for the State of Texas 

show 590 acres declared irrigated above station. City of Brownwood pumps 

water just below station. Two small pumps below control dam, but amount 

of water diverted not known.

REGULATION. Flow at station regulated during normal flow by storage reservoir 

and pumping plants above. The city of Brownwood has a dam 2 miles above 

station to impound water for municipal use. Water is released from this 

reservoir when the supply is short in the pond at the gage from which the 

city supply is pumped. Backwater from the lower dam extends to upper 

dam. No regulation of consequence from irrigation above station.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined 

below 4,000 second-feet and poorly defined above. Gage read to hundredths twice daily and oftener during floods. Mean daily discharge determined by applying mean daily gage height to rating table, averaging discharge for intervals of a day on days of considerable fluctuation. Records 

good.

The following discharge measurements were made: 

November 10*, 1924: Gage height, 0.18 foot; discharge, 0 second-foot. 

May 19, 1925: Gage height, 1.07 feet; discharge, 19.2 second-feet. 

September 10, 1925: Discharge, 0 second-foot.

China Creek, 2 miles northwest of San Saba, San Saba County, and 3 miles 

below mouth of Richland Creek.

DRAINAGE ABEA. 3J04Q square miles (measured on topographic maps arid base 

map of Texas).

RECORDS AVAILABLE. December 30, 1904, to December 31, 1906; September 11, 

1915, to September 30, 1925. Miscellaneous discharge measurements 

previous to 1904.

GAGE. Vertical and inclined staff on right bank; read by G. M. Pool.

DISCHARGE MEASUREMENTS. Made by wading or from highway bridge.

CHANNEL AND CONTROL. Channel straight for 100 feet above and below station. 

Bed composed of rock and gravel; shifts. Left bank of gravel and clay, 

wooded, and not subject to overflow; right bank of clay and gravel, wooded, 

and subject to overflow during high water. A shoal at a ford about 75 feet 

below gage serves as control during medium and low stages; shifts.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 15.0 feet 

during night of May 11 and August 27 (discharge, 4,660 second-feet); 

minimum stage, 0.56 foot at 7.30 p. m. July 25 (discharge, 0.6 second-foot). 

1904-1906; 1915-1925: Maximum stage recorded, about 37.0 feet April 

26 or 27, 1922, determined from floodmarks on gage (discharge, not determined); no flow August 9 and 10, 1918.

DIVERSIONS. Considerable water is diverted from stream and tributaries above 

station. There are also diversions below station but none near station. 

Flood water from Brady Creek at Brady is stored for municipal uses; capacity 

of reservoir not known, but probably small. Records of the Board of Water 

Engineers for the State of Texas show that about 9,300 acres have been 

declared irrigated by diversions above station and about 2,700 acres bydiversions below station.

HEGULATIOK. None.

ACCURACY. Stage-discharge relation not permanent. Rating curve well 

defined. Gage read to hundredths twice daily. Daily discharge determined by applying mean daily gage height to rating table. Shifting-control 

method used October 1-16. Records good.

Bear Creek, 2^ miles above North Llano highway bridge, ftttd 3 mile* 

northwest of Junction, Kimble County.

DRAINAGE AREA. -914 square miles (measured on topographic Maps and base 

map of Texas).

RECORDS AVAILABLE. September 14, 1915, to September 30, 1925.

GAGE. Au continuous water-stage recorder on left bank; installed August 1, 

1925; inspected by Gilford Evans. Prior to that, chain gage on left bank; 

read by W. M. Keen.

DISCHARGE; MEASUREMENTS. Made by wading or from highway bridge> 2% 

miles below station.

CHANNEL AND CONTROL. Bed composed of solid rock. Channel straight above 

and beiow for 400 feet, with a series of pools and rapids. Left bank not 

subject to overflow. Right bank wooded and subject to overflow during 

high stages. One channel at all stages. Current sluggish at gage during 

low and medium stages. A solid-rock ledge of approximately 2-foot vertical 

fall at site of old dam serves as permanent control for medium and low 

stages, except.slight effect from accumulation of moss during low stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 19.03 fe6t 

at 6 a. m. May 29 (discharge, 32,600 second-feet, determined by slope 

method and subject to error); minimum discharge, 11 second-feet April 

24-26, August 21-31, September 1-11, and 23.

1915-1925: Maximum stage recorded, 23 feet about midnight April 24, 

1923 (discharge, 43,100 second-feet, determined from extension of rating 

curve and subject to considerable error); no flow during several periods.

DIVERSIONS.- Records of the Board of Water Engineers for the State of TexAS 

show that about 1,200 acres have been declared irrigated by diversion 

above station. During low stages such diversions materially reduce flow at 

station.

REGULATION* No indication that flow at station is regulated.

ACCURACY. Stage-discharge relation not permanent. Rating curve well 

defined below 1,400 second-feet and extended above through two slope 

measurements. From October 1 to July 31, gage read to hundredths 

twice daily and operation of water-stage recorder satisfactory thereafter. 

Daily discharge determined by applying mean daily gage height to rating 

table, averaging discharge fo? intervals of a day on days of eonsiderable 

fluctuation; shifting-control method used May 30 to September 30. Records 

below discharge of 1,400 second-feet, good; poor, above.

ILANO RIVER NEAR JUNCTION, TEX.

LOCATION. 100 feet north of Kerrville-Junction road, 3 miles below confluence 

of North Llano and South Llano Rivers, and 3J^ miles east of Junction, 

Kimble County.

DRAINAGE AREA. 1,760 square miles (measured on topographic maps and base 

map of Texas). -

RECORDS AVAILABLE. September 13, 1915, to September 30, 1925.

GAGE. Au continuous water-stage recorder on right bank; inspected by Gilford 

Evans. Prior to August 14 combination vertical and inclined staff were 

used; read by Bonnie Oliver.

DISCHARGE MEASUREMENTS. Made by wading or from cable 400 feet above gage.

CHANNEL AND CONTROL. Bed composed of solid rock; permanent. Channel 

straight for 700 feet above and 350 feet below gage. Left bank slightly 

wooded and subject to overflow during high water; right bank not subject to 

overflow. One channel at all stages, except above a stage of 11.3 when a 

small part of flow may follow a slough that leaves the river a short distance 

above gage and enters the main stream below gage. Control for low and 

medium stages is a rock ledge 75 feet below gage, having a fall of about 

3 feet; permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 23.3 feet 

May 29, determined by leveling to floodmarks (discharge, 76,900 secondfeet, determined from extension of rating curve); minimum stage, 1.58 feet 

April 22-26 (discharge, 74 second-feet).

1915-1925: Maximum stage recorded, 26.3 feet at 3 a. m. September 16, 

1915 (discharge, 98,800 second-feet, determined from extension of rating 

curve and subject to considerable error); minimum stage, 1.32 feet during 

August 23-28, 1918 (discharge, 13 second-feet).
Disc,

COLORADO RIVER BASIN 149

DIVERSIONS. Records of! the Board of Water Engineers for the State of Texas 

show that about 2,500 acres have been declared irrigated by diversions above 

station and about 1,&00 acres below station. Diversions materially reduce 

flow at station during low stages.

REGULATION. Slight regulation by water-power plant on South Llano River 

at junction. I

ACCURACY. Stage-discharge relation not permanent. Standard rating curve 

well defined below 1,700 sejcond-feet and extended above through .two slope 

measurements; extension subject to considerable error. Gage read to hundredths once daily flrom October 1 to August 14, and operation of waterstage recorder satisfactory thereafter. One reading daily may not be true 

index to mean daily! discharge during medium and high stages owing to 

rapid fluctuations. l)aily discharge determined by shifting-control method 

October 1 to November 30 and August 14 to September 30; for remainder 

of year by applying jnean daily gage height to rating table. Records prior 

to August 14, fair; good thereafter.

COLORADO RIVER BASIN

BARTON SPRINGS AT AUSTIN, TEX.

157

LOCATION. Barton Springs issue from channel of Barton Creek, 1,600 feet above 

Austin-Bee Cave highway bridge, half a mile above confluence with ColoradoRiver, and half a mile southwest of Austin, Travis County.

RECORDS AVAILABLE. October 1, 1918, to September 30, 1925. Daily record of 

flow of Barton Creek, which closely approximates flow of Barton Springs, as 

the ordinary flow of the creek is from the springs, has been published from 

April 25, 1917, to September 30, 1918. Miscellaneous discharge measurements of Barton Creek made from 1894 to 1906 and during 1916 and 1917.

DISCHARGE MEASUREMENTS. Made by wading Barton Creek above and below 

the springs in order to determine the flow of springs as indicated in table 

below.

LITTLE WALNUT CREEK NEAR AUSTIN, TEX.

VTION. At Austin-Manor highway bridge, 13^ miles above confluence with 

Walnut Creek and 43^ miles northeast of Austin, Travis County.

DRAINAGE AREA. 12 square miles (measured on topographic maps).

RECORDS AVAILABLE. April 25, 1924, to September 30, 1925.

GAGE. Gurley 8-day water-stage recorder attached to downstream side of first 

concrete pier from right bank; inspected by Geological Survey engineers.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of clay; shifts. Channel winding above 

gage and straight for 150 feet below. Banks of gravel and clay; high; steep; 

shift. Control of clay, 150 feet below gage; shifts.

EXTREMES OP DISCHARGE. Maximum stage during year from water-stage 

recorder, 3.25 feet at 9 p. m. May 7 (discharge, 815 second-feet); no flow 

during several periods.

1924-1925: Maximum stage recorded, 4.90 feet during night of September 

21, 1924 (discharge not determined); no flow for several periods in 1925.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined 

below 15 second-feet, poorly defined from 15 to 53 second-feet, and extended 

above this on basis of measurements made during 1926. Operation of waterstage recorder satisfactory except for breaks in record as indicated in footnote 

to daily-discharge table. Daily discharge determined by applying to rating 

table mean daily gage height ascertained from recorder graph by inspection 

or by use of planimeter, averaging discharge for intervals of a day on days of 

considerable fluctuation. Records for low stages, fair; for high stages, poor.

COLORADO RIVER BASIN

ONION CREEK HEAR DEL VAIIE, TEX.

159

Williamson Creek and 2J^ miles southwest of Del Valle, Travis County.

DBAINAGE AREA. 337 square miles (measured on topographic maps and base 

map of Texas).

RECORDS AVAILABLE. May 15, 1924, to September 30, 1925.

GAGE. Vertical staff attached to rock 250 feet above low-water concrete bridge; 

read by C. T. Sundberg.

DifJCHARGE MEASUREMENTS. Made by wading, from low-water concrete bridge, 

or from highway bridge 2 miles downstream.

CHANNEL AND CONTROL. Bed composed of solid rock with some gravel. 

Channel straight for 500 feet above and 200 feet below gage. One channel 

at all stages. Right bank of rock and clay; fairly clean to a stage of 8 feet 

and above this point is covered with grass, light brush, and small trees; 

permanent; subject to overflow at extremely high stages. Left bank is 

ledge rock; clean up to a stage of 8 feet and above this point is covered with 

fairly heavy growth of brush and small trees; permanent; not subject to 

overflow. Control is formed by rock and gravel rapids and low-water 

concrete bridge, 250 feet below gage.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 5.90 feet at 

9.25 a. m. September 12 (discharge, 254 second-feet); no flow during several 

periods.

1924-1925: Maximum stage recorded, 10.05 feet at 8 a. m. June 22, 1924 

(discharge, 8,240 second-feet, determined from extension of rating curve 

subject to considerable error); no flow several periods in 1925.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Rating curves fairly well 

defined below 1,000 second-feet and poorly defined above. Gage read to 

hundredths twice daily, but during rapidly changing stage mean of two 

readings daily may not be true index to mean daily discharge. Daily discharge 

determined by applying mean daily gage height to rating table, averaging 

discharge for intervals of a day on days of considerable fluctuation. Dailydischarge records not sufficiently accurate to warrant publication. Monthly 

discharge fair.

recorder was not in operation, and reached a height of about 32.2 feet as 

determined from floodmarks on gage house (discharge not determined); 

minimum stage recorded, approximately 0.58 foot from 9 to 10 a. m. 

November 1, 1917 (discharge, 80 second-feet, determined from extension 

of rating curve; possibly slightly in error).

A stage of 37.6 feet was reached November 4, 1913.

DIVERSIONS. There are numerous small diversions above station for irrigation 

and municipal uses, but flow is probably not materially affected thereby, 

except possibly during extremely low stages.

REGULATION. Flow partly regulated during low and medium stages by operation 

of water-power plants upstream, chiefly by a plant about 8 miles above.

ACCURACY. Stage-discharge relation not permanent. Rating curve well defined. 

Operation of water-stage recorder satisfactory, except for breaks in record 

as indicated in footnote to daily-discharge table. Daily discharge determined 

by shifting-control method, averaging discharge for intervals of a day for 

days of considerable fluctuation. Records good.

SAW MAEOOS BIVER AT OTTOTE, TEX.

LOCATION. At highway bridge one-fourth mile southwest of Ottine, Gonzales 

County, and 4 miles below mouth of Plum Creek.

DRAINAGE AREA. Indeterminate. .

RECORDS AVAILABLE. June 22, 1915, to September 30, 1925.

GAGE. Stevens continuous water-stage recorder on right bank just below pier 

installed March 27, 1925. Chain gage attached to upstream handrail of 

bridge used prior to that date; read by W. C. Meek.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand, clay, and gravel; shifts. 

Banks wooded. Right bank subject to overflow at gage height of 28.7 feet 

and left bank at 34.0 feet. Channel straight above and below station for 

150 feet. Low-stage control is a shoal 150 feet below gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, about 9.5 

feet, determined from silt marks in well April29 (discharge, 1,480 second-feet). 

Owing to regulation no flow at noon March 31.

1915-1925. Maximum stage recorded, 37.5 feet at 7.30 a.m. May 16, 

1920 (discharge, 45,600 second-feet); no flow at 6.30 p. m. July 29, 1923, 

and at noon March 31, 1925.

DIVERSIONS. Small amounts of water are diverted above station for irrigation 

and municipal uses, but only a small part of total.run-off is used. Little 

water, if any, is diverted below station.

REGULATION. Flow regulated by operation of small cotton gin a short distance 

above station. Operation of several small water-power plants in upper 

drainage basin near San Marcos and Martindale does not materially affect 

flow at this station.

ACCURACY. Stage-discharge relation not permanent. Rating curve well defined. 

Gage read to hundredths twice daily from October 1 to March 27. Operation of water-stage recorder satisfactory thereafter. Mean of two readings 

daily may not be true index to discharge owing to power regulation. Daily 

discharge determined by shifting-control method, averaging discharge for 

intervals of a day on days of considerable fluctuation, except discharge estimated or partly estimated April 29-30, May 1, June 17,26, and 27. Records 

fair.

SAN ANTONIO RIVER AT SAN ANTONIO, TEX.

LOCATION. At South Alamo Street B|ridge in San Antonio, Bexar County, 4

miles below San Antonio Springs, the source of normal flow of river, and 1%

miles above mouth of San Pedro Creek. 

DRAINAGE AEEA. Indeterminate. 

RECOEDS AVAILABLE. January 26, 1915, to September 30, 1925. Miscellaneous

discharge measurements were made from 1895 to 1906. 

GAGE. Gurley graph water-stage recorder on right bank at downstream side of

bridge; attended by employees of city of San Antonio. 

DISCHAEGE MEASUEEMENTS. Made from bridge or by wading. 

CHANNEL AND CONTROL. Channel is straight for 100 feet below gage and curved

above. Bed composed of sand, gravel, and silt. Control formed by gravel

bar; shifts. 

EXTREMES OF DISCHAEGE. Maximum stage during year from water-stage

recorder, 4.50 feet at 4 p. m. May 10 (discharge, 641 second-feet); minimum

discharge, 5.1 second-feet at 10 a. m. July 12.

1914-1925: Maximum stage recorded, 20.14 feet at 3 a. m. September 10,

1921, determined from floodmarks on gage (discharge, 15,300 second-feet,

determined by slope method, using value of 0.035 and 0.050 for "n" in

Kutter's formula). Minimum discharge, 5.1 second-feet at 10 a. m. July 12,

1925. City of San Antonio turned flow from well into river in summer of

1925 to keep it from going dry.
GTJADALTJPE RIVER BASIN 173

DIVERSIONS. Quantity of water diverted above gage not known but is probably 

immaterial. Considerable land is irrigated from diversions below gage.

REGULATION. Operation of water wheels at Guenther flour mills, just above 

gage, causes sharp fluctuations in stage.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve 

fairly well defined. Operation of water-stage recorder not satisfactory. 

Daily discharge determined by shifting-control method, averaging discharge 

for intervals of a day on days of rapid fluctuations, or as noted in footnote 

to daily-discharge table. Records good.

The normal flow of San Antonio River comes from springs within city limits, 

tout two tributaries from north furnish considerable run-off at times of heavy 

precipitation. Changes in mean daily stage during low flow are believed to be 

due to pumping from deep wells for the city water supply and the use of artesian 

"water for irrigation in areas adjacent to the river, for it is thought that the wells 

draw from the underground reservoir that feeds river by springs.

SAN ANTONIO RIVER AT CAIAVEEAS, TEX.

LOCATION. One-fourth mile south of San Antonio & Aransas Pass Kailway 

station in Calaveras, Wilson County, and 1 mile below mouth of Calaveras 

Creek.

DRAINAGE AREA. 1,780 square miles (measured on topographic maps, progressive military maps of United States Army, and base map of Texas).

EECORDS AVAILABLE. March 12, 1918, to August 31, 1925, when station wasdiscontinued.

GAGE. Vertical staff on left bank near old brick plant; read by I. M. Smith 

or E. H. Moore.

DISCHARGE MEASUREMENTS. Made from highway bridge half a mile above gage 

or by wading.

CHANNEL AND CONTROL. Bed of sand and clay; shifts. Channel straight for 

150 feet above and below station. Left bank wooded and not subject to 

overflow; right bank wooded and subject to overflow only at extremely 

high stages. Old bricks piled into channel form a semipermanent low-water 

control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 11.97 feet at 

8 a. m. December 3 (discharge, 1,600 second-feet); minimum discharge, 

48 second-feet August 21 and 22.

1918-1925: Maximum stage recorded, 42.0 feet at 4 a. m. September 11, 

1921 (discharge not determined); minimum discharge, 15 second-feet at 8.30' 

a. m. September 14, 1918.

DIVERSIONS. Medina Dam and Eeservoir, with a storage capacity of 254,000 

acre-feet, is on Medina Eiver about 50 miles above its confluence with San 

Antonio Eiver. Four miles below Medina Dam are diversion works, with a 

capacity of 850 second-feet. There were probably about 5,000 acres under 

irrigation in this project in 1922.

EEGTTLATION. The ordinary flow may be slightly affected by storage and diversions on Medina Eiver.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve 

well defined between 30 and 1,500 second-feet and extended above by means 

of AVd method based on measurement made at a discharge of 11,000 secondfeet and subject to error. Gage read to hundredths twice daily, but mean of 

two readings daily may not be true index to discharge, owing to rapid fluctuations. Daily discharge determined by shifting-control method. Eecords 

poor.

GTTADALTTPE RIVER BASIN 179

SAW PEDEO CREEK AT SAW AWTOWIO, TEX.

LOCATION. At south end of Missouri, Kansas & Texas Railway culvert, 200 feet 

south of Arsenal Street crossing, 1 mile above mouth of Salsamora and 

Martinez Creeks, 2 miles below San Pedro Springs, its source, and 2^ miles 

above confluence with San Antonio River.

DRAINAGE AREA. Indeterminate.

RECORDS AVAILABLE. July 20, 1916, to September 30, 1925.

GAGE. Gurley 7-day water-stage recorder; inspected by engineers of city of 

San Antonio.

DISCHARGE MEASUREMENTS. Made by wading or from bridge in vicinity.

CHANNEL AND CONTROL. Bed and banks composed of smooth concrete; permanent. Low-stage control is a 4 by 4 inch timber bolted across bed of flume. 

Channel straight above and below station.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage 

recorder, 4.8 feet at 1.45 p. m. May 10 (discharge, 680 second-feet, determined 

from extension of rating curve and subject to error); minimum stage, 0.35 

foot for short period October 6-9 (discharge, 0.90 second-foot).

1916-1925: Maximum stage recorded, 8.6 feet at 11.30 p. m. September 9, 

1921, when backwater from Alizan Creek existed (discharge not determined)! 

minimum stage, 1.30 feet December 10 and 11, 1918 (discharge, 0.7 secondfoot).

DIVERSIONS. None.

REGULATION. Flow partly regulated by small dam at swimming pool in San 

Pedro Park, a few miles above.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve 

well defined below 200 second-feet and extended above by means of Kutter's 

formula, with a value for "n" of 0.014 at a 6-foot gage height. Operation of 

water-stage recorder not satisfactory as shown by breaks in record. Daily 

discharge determined by shifting-control method, averaging discharge for 

intervals of a day on days of considerable fluctuation, or as noted in footnote 

to daily-discharge table. Records good.

Entire flow of San Pedro Creek, except during times of heavy precipitation, is 

furnished by San Pedro Springs, and flow at this station is believed to be that 

which reaches San Antonio River. Martinez and Salsamora Creeks carry 

no water except during heavy local rains and have been known to be dry for 

several years at a time.

thickly wooded with small trees and brush, and does not overflow; left bank 

of sand, gravel, and rock, sparsely covered with small trees, and begins to 

overflow at a stage of 9 feet. Low-water control, up to a stage of about 1.2 

feet, consists of a concrete weir, 100 feet below gage. Weir is about 1.5 

feet high for a width of 95 feet with abutments 4 feet higher than crest. A 

rock riffie 600 feet below gage serves as control for medium stages.

^EXTREMES OP DISCHARGE. Maximum stage recorded during year, 12.42 feet at 

10 p. m. May 28 (discharge, 8,640 second-feet, determined from extension 

of rating curve and subject to considerable error); minimum stage, 0.56 foot 

August 29 (discharge, 2.7 second-feet, determined from extension of rating 

curve and subject to error).

1922-1925: Maximum stage recorded, 15.36 feet at 1 p. m. April 25, 1923 

(discharge not determined); minimum stage that of August 29, 1925.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve 

well defined below 300 second-feet and extended to 1,500 second-feet by means 

of formula Q= C L h 3/2, using coefficient for C derived from meter measurements at station and extended to 6,100 second-feet through three float 

measurements. Operation of water-stage recorder satisfactory. Daily 

discharge determined by shifting-control method, averaging- discharge for 

intervals of a day on days of considerable fluctuation. Records for low stages 

good and for high stages poor.

MEDINA CANAL NEAR RIOMEDINA, TEX.

LOCATION. Just above upper end of flume No. 1 on Medina Valley Irrigation 

Co.'s main canal, one-third mile below head of canal and 6 miles northwest 

of Riomedina, Medina County.

RECORDS AVAILABLE. March 30, 1922, to September 30, 1925. Station maintained during irrigation seasons of 1920 and 1921 by United States Department of Agriculture in cooperation with Texas Board of Water Engineers 

for seepage studies.

GAGE. Gurley graph water-stage recorder with inside and outside staff gages; 

inspected by J. B. Milam.

DISCHARGE MEASUREMENTS. Made by wading orfrom foot plank just above gage.

CHANNEL AND CONTROL. Metal flume and concrete-lined canal; permanent.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage 

recorder, 2.03 feet June 5 and 6 (discharge, 128 second-feet); no flow 

December 3-9, January 11, 12, and August 17 to September 30.

1922-1925: Maximum discharge recorded, 128 second-feet June 26, 1923, 

and June 5 and 6, 1925. No 'flow for several periods.

DIVERSIONS. Above all diversions from canal.

REGULATION. Flow controlled by head gates. Canal ordinarily carries a small 

flow during nonirrigation season for domestic and stock water uses.

ACCURACY. Stage-discharge relation permanent. Rating curve fairly well 

defined. Operation of water-stage recorder satisfactory. Daily discharge 

determined by applying to rating table mean daily gage height determined 

from recorder graph by inspection or by use of planimeter, averaging discharge for intervals of a day on days of considerable fluctuation. Records good.

Canal diverts from right bank of Medina River, 

near Lacoste and Natalia.

SURFACE WATER SUPPLY, 1925, PART VIII 189

NUECES RIVER BASIN

NtJECES RIVEE AT IAGUNA, TEX.

LOCATION. 1 mile northwest of Laguna, Uvalde County, 2.6 miles above LagunaUvalde road crossing, and 7^4 miles below mouth of Montell Creek.

DKAINAGE AREA. 764 square miles (measured on topographic maps, base map 

of Texas, and progressive military maps of United States Army.

RECORDS AVAILABLE. October 25, 1923, to September 30, 1925.

GAGE. Stevens water-stage recorder on right bank; inspected by J. W. Bones. 

Prior to January 25, 1925, combined vertical and inclined staff on right 

bank, 2 miles downstream; read by Lilly Secrest.

DISCHARGE MEASUREMENTS. Made from cable or by wading.

CHANNEL AND CONTROL. Channel straight for 500 feet above and 2,400 feet 

below gage. Bed composed of rock; permanent. Right bank of rock, 

clean, permanent, and not subject to overflow; left bank of rock, gravel, 

and earth, covered with trees and brush, 1,000 feet of it subject to overflow 

at extremely high stages. Control is rock and gravel shoal 800 feet below 

gage; fairly permanent. Prior to January 25, 1925, at extremely low 

stages large part of flow probably went through gravel bar on left bank.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage recorder, 12.0 feet at 1 a. m. May 30 (discharge, 15,600 second-feet); minimum 

stage, 0.43 foot October 1-3 (discharge, 12 second-feet).

1924-1925: Maximum stage that of May 30, 1925; minimum discharge, 

8.9 second-feet September 9-11, 1924.

By levels to distinct drift line, the flood of September 21, 1923, reached a 

stage of 23.23 feet. The flood of 1913 reached about the same stage. 

Floods in 1903 reached a slightly higher stage.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation probably permanent. Rating curves 

fairly well defined. Gage read to hundredths twice daily prior to January 25 

and operation of water-stage recorder satisfactory thereafter, except as 

shown by breaks in record. Daily discharge determined by applying mean 

daily gage height to rating table. Prior to January 25, it is believed that 

part of low-water flow passed through large gravel bar at station and was 

not measured. Records prior to January 26, fair; good, thereafter.

NUECES RIVER NEAR CINONIA, TEX.

LOCATION. Just below suspension bridge near Oswald ranch, 2 miles east of 

Cinonia, Zavalla County, and 8 miles northeast of Crystal City.

DRAINAGE AREA. 2,150 square miles (measured on topographic maps, progressive military maps of United States Army, and base map of Texas).

RECORDS AVAILABLE. July 5, 1915, to September 30, 1925, when station was 

discontinued.

GAGE. Vertical staff on right bank, 200 feet below highway bridge; read by 

J. W. Lowe or R. Johnson.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by wading.
NUECES RIVER BASIN 191

CHANNEL AND CONTROL. Bed of clay and gravel. Banks wooded; subject to 

overflow at extremely high stages. Channel straight above and below 

station. An artificial concrete control was completed at site of gage on September 23, 1917; point of zero flow, 0.85 foot.

EXTREMES OF DISCHARGE. Maximum stage recorded during year by leveling to 

floodmarks about 50 feet 2 to 9 a. m. May 31 (discharge not determined); 

minimum stage, 1.14 feet May 28 (discharge, 2.2 second-feet).

1915-1925: Maximum stage recorded that of May 31, 1925. No flow 

during several periods of record. i

According to local residents, the greatest flood on record occurred in 1913, 

when river reached a stage of about 53.2 feet by present gage datum. 

DIVERSIONS. Considerable water diverted above station for irrigation; amount

not known. 

REGULATION. None.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined 

below 700 second-feet and extended above. Gage read to hundredths twice 

daily. Daily discharge determined by applying mean daily gage height to 

rating table. Records good.

Backwater from a dam 40 feet high, about 20,miles below station, extends within 

2 miles of station when reservoir is full. A large part of flow of river is known to 

seep into bed near Uvalde and return to surface just above station. The condition of the underground water may have an effect on this return water and 

thus help to equalize flow.

The following discharge measurements were made:

February 24, 1925: Gage height, 1.42 feet; discharge, 11.3 second-feet.

June 11, 1925: Gage height, 4.13 feet; discharge, 182 second-feet.

Daily discharge, in second-feet, of Nueces River near Cinonia, Tex., for the year 

ending September SO, 1925

NUECES RIVER AT COTU1LA, TEX.

LOCATION. 100 feet above Farmer Dam, half a mile below International-Great 

Northern Railroad bridge, 1.9 miles, by road, from post office at Cotulla, 

La Salle County, and 3 miles below mouth of Salt Creek.

DRAINAGE AREA. 5,260 square miles (measured on topographic maps, progressive military maps of United States Army, and base map of Texas).

RECORDS AVAILABLE. October 31, 1923, to September 30, 1925.

GAGE. Vertical staff on left bank; read by Kathleen Lind.

DISCHARGE MEASUREMENTS. Made from highway bridge 1 mile upstream or 

from railroad bridge.

CHANNEL AND CONTROL. Bed composed of sand and silt. Channel straight for 

1 mile above and below gage. Right bank of earth, covered with rushes and 

cat-tails, and at a stage of 3.5 feet is subject to overflow; left bank of earth, 

wooded, and subject to overflow at extremely high stages. Low-water 

control is a concrete and rock dam, 100 feet below gage. No vegetation on 

control proper, but much of the dam is only a few inches high and there is 

much aquatic growth just above dam which may affect stage-discharge 

relation. This control probably submerged at a stage of about 2 feet. At 

about a 4-foot gage height, another dam farther downstream probably 

serves as control and this dam is probably submerged at a stage of 6 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 14.89 feet 

from 10 a. m. to 1 p. m. June 3 (discharge, 49,500 second-feet); no flow 

during several periods.

1924-1925: Maximum stage that of June 3, 1925; no flow for several 

periods.

DIVERSIONS. Most of low-water flow is diverted by pumping from storage 

reservoirs above; amount not known.

REGULATION. Low-water flow regulated by storage reservoirs above.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined. 

Gage read to hundredths twice daily and oftener during flood periods. 

Daily discharge determined by applying mean daily gage height to rating 

table. Records fair.

GAGE. Vertical staff attached to pipe-line support of old pump house; read 

by John W. Cunningham.
196 SURFACE WATER SUPPLY, 1925, PART VIII

DISCHARGE MEASUREMENTS. Made by wading at backwater or from cable 125 

feet below gage.

CHANNEL AND CONTROL. Bed composed of clay and gravel. Channel straight 

above and below station. Left bank wooded and bordered by levee constructed to prevent overflow; right bank wooded and not subject to overflow. Breakwater dam, which is loose rock fill half a mile below, serves as 

control. It leaks badly and is subject to change during floods. Flood 

damage is repaired by dumping loose rock on crest.

EXTREMES OF STAGE. Maximum stage recorded during year, 9.20 feet at 8 

a. m. June 16; minimum stage, 0.20 foot at 4 p. m. November 7.

1915-1925: During September, 1919, the river reached a stage of about 

12 feet, as determined from floodmarks on gage. This was not only the 

highest stage reached during period covered by records but probably 

exceeds any that occurred for many years prior to the establishment of 

this station. Discharge indeterminate because of lowlands on left bank 

overflowing for a width of several miles. ,No flow August 23-28, 1918.

DIVERSIONS. Considerable water taken from river for irrigation immediately 

above station, and river water is also used for irrigation throughout drainage above. City of Corpus Christi pumps water just below gage for municipal supply. They reported a consumption of 922 acre-feet during 1918.

REGULATION. None of consequence^

ACCURACY. Stage-discharge relation not permanent because of leakage through 

and repair to breakwater dam. Rating curve poorly defined. Gage read to 

hundredths twice daily. Daily discharge not computed because of changing 

control and insufficient discharge measurements. Records poor. 

No discharge measurements were made at this station since 1919.

at all stages. Channel straight for half a mile above and below gage. Right 

bank wooded, permanent, and not subject to overflow. Left bank permanent and not subject to overflow. Low-water control is gravel riffle, 150 

feet below staff gage; will probably shift during floods and during dry season 

weeds and grass grow on control. High-stage control is narrow section in 

river, 500 feet downstream from low-water control. Stage of change of 

control not known.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.30 feet May 

11 (discharge not determined). No flow for several periods.

1924-25: Maximum stage occurred in 1925. No flow during large part of 

1924 and 1925.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent. Rating curve poorly defined 

below 135 second-feet. Gage read to hundredths twice daily. Daily discharge determined by applying mean daily gage height to rating table. 

Records fair.

The station was visited December 2, 1924, by J. W. Bones, and no flow recorded.

CHANNEL AND CONTROL. Bed composed of rock, sand, and gravel. Channel 

curved above and below station, but straight at gage for 150 feet. Banks 

wooded and subject to overflow at extremely high stages. A concrete dam, 

50 feet below gage, serves as control during low and medium stages; position 

of high-water control not known. Point of zero flow, gage height 0.07 foot, 

except when affected by moss on control.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 3.34 feet at 

8 a. m. May 12 (discharge, 874 second-feet); no flow for several periods.

1915-1925: Maximum stage recorded, 18.5 feet September 18, 1919 (discharge, 34,400 second-feet determined from extension of curves and subject 

to error); no flow during several periods of each year.

DIVERSIONS. Small areas are irrigated by diversions in headwaters, but available 

information does not show that water is taken from stream immediately 

above station.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined. 

Gage read to hundredths twice daily. Daily discharge determined by applying mean daily gage height to rating table. Records good.

The following discharge measurements were made:

December 3,1924: Gage height, 0.13 foot; discharge estimated, 1.0 second-feet.

June 29, 1925: Discharge, 0 second-foot.

LOCATION. Half a mile below mouth of San Miguel Creek, 1 mile north of 

Calliham, McMullen County, and 12 miles west of Three Rivers.

DRAINAGE AREA. 5,450 square miles (measured on topographic maps, progressive military maps of United States Army, and base map of Texas).

RECORDS AVAILABLE. October 1, 1924, to September 30, 1925.

GAGE. Vertical staff in three sections on right bank attached to trees; read 

by J. C. Scroggins.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Channel straight for 700 feet above and 800 feet 

below gage. Bed composed of sandy clay; shifts. Right bank wooded, 

sodded, and not subject to overflow; left bank wooded, sodded, and at high 

stages is subject to overflow for 400 feet. Control is concrete dip, 100 feet 

below gage. There are five pipes under the slab to carry the low flow. 

Pipes clog and affect stage-discharge relation.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 16.1 feet at 

10.50 a. m. March 22 (discharge, 4,140 second-feet); no flow for several 

periods.

DIVERSIONS. Some water diverted above; amount not known.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Rating curve well defined. 

Gage read to hundredths twice daily but gage-height record doubtful. 

Daily discharge determined by applying mean daily gage height to rating 

table. Shifting-control method used August 3-12 and September 1-30. 

Discharge estimated for several periods. Daily discharge not sufficiently 

accurate for publication. Records poor.

BIO GRANDE AT LANGTBY, TEX.

LOCATION. At east end of canyon section, half a mile from Langtry, Val Verde 

County, and 13 miles above mouth of Pecos River.

DBAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 1, 1900, to October 15, 1914; December 1, 1919, 

to March 31, 1920; January 20, 1924, to September 30, 1925.

GAGE. Vertical and inclined staff on right bank; read by H. T. Dodd.

DISCHARGE MEASUREMENTS. Made from cable 500 feet below gage or by wading.

CHANNEL AND CONTROL. Channel straight for 1 mile above and one-fourth 

mile below station. One channel at all stages. Bed consists of sand and 

gravel; fairly permanent. Right bank of rock, permanent, and not subject 

to overflow. Left bank of rock overlain with sand and not subject to overflow. Control is sand, gravel, and boulder riffle, 1,000 feet below gage; 

probably shifts at high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 18.0 feet at 

8 a. m. May 29 (discharge, 50,000 second-feet, determined from extension 

of rating curve and subject to considerable error); minimum stage, 1.2 

feet from 8 a. m. April 22 to 8 a. m. April 25 and 5 p. m. May 6 to 5 p. m. 

May 8 (discharge, 995 second-feet).

1900-1914; 1919-1920; 1924-1925: Maximum stage recorded, 34.25 

feet September 13, 1904 (discharge, 132,000 second-feet); minimum discharge, 270 second-feet May 8 to 13, 1904. A float measurement by W. H. 

Dodd on September 16, 1919, at a stage of 46.9 feet, present gage datum 

(by levels to point shown by W. H. Dodd) showed discharge of 152,000 

second-feet. A stage of 56.9 feet, present gage datum, was reached about 

June 18, 1922; determined by leveling to floodmark made by W. H. Dodd.

DIVERSIONS. Considerable water is diverted in Colorado, New Mexico, Texas, 

and Mexico; amount not known. Records of the Board of Water Engineers 

for the State of Texas show that about 180,000 acres were irrigated in 1920 

by diversions below station, practically all of which is in Hidalgo and Cameron 

Counties.

REGULATION. Flow partly regulated by storage at Elephant Butte Dam, 120 

miles above El Paso, and on Mexican tributaries.

ACCURACY. Stage-discharge relation not permanent. Rating curves used 

from October 1 to May 27 well defined below 3,000 second-feet and poorly 

defined above, and one used from May 28 to September 30, is well defined below 

34,000 second-feet and extended above. Gage read to tenths or half-tenths 

twice daily, and oftener during floods. Daily discharge determined by 

applying mean daily gage height to rating table. Records good.

RIO GRANDE HEAR BROWNSVILLE, TEX.

LOCATION. Opposite Matamoros, Tamaulipas, Mexico, half a mile above international railroad bridge and 1 mile above Brownsville, Cameron County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 29, 1900, to March 31, 1914 (discharge not computed); October 1, 1922, to September 30, 1925.

GAGE. Stevens continuous water-stage recorder.

DISCHARGE MEASUREMENTS. Made from cable near gage.
BIO GEA.NDE BASIN 225

CHANNEL AND CONTROL. Bed of sand; shifting. Channel straight for 500 feet 

above and 2,000 feet below station. Both banks of sand and clay; subject 

to overflow at extremely high stages. Control consists of sand; shifts.

EXTREMES OF DISCHARGE. Maximum mean daily discharge, 26,700 secondfeet September 12; minimum mean daily discharge, 225 second-feet May 30. 

1923-1925: Same as given above.

DIVERSIONS. Considerable water diverted in Colorado, New Mexico, Texas, 

and Mexico; amount not known.

Between Roma and Brownsville there are many lagoons (old river channels) that take river water during moderate floods, and a large area is overflowed deeply in large floods. Much of this water returns slowly to the 

river as the floods subside, thus making the flow more uniform at Brownsville than at Roma. During extremely high stages, large quantities also 

leave the river entirely, reaching the Gulf of Mexico by other channels.

REGULATION. Flow partly regulated by storage at Elephant Butte Dam, 120 

miles above El Paso.

COOPERATION. Records furnished by the Mexican section of International 

Boundary Commission.

Discharge measurements of Rio Grande near Brownsville, Tex., during the year 

ending September SO, 1925

PECOS RIVER HEAR MALAGA, N. HEX.

LOCATION. In sec. 18 or 19, T. 24 S., R. 29 E., 3J^ miles southeast of Malaga,

Eddy County, 4J^ miles below mouth of Black River. 

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 1, 1920, to September 30, 1925. 

GAGE. Stevens 8-day water-stage recorder on right bank; inspected by

W. F. Gerlach,

DISCHARGE MEASUREMENTS. Made from cable or by wading. 

CHANNEL AND CONTROL. Bed composed of solid rock covered with sand; shifts.

Right bank solid rock and steep; left bank sand and high. Control is rock

ledge overlain with sand, 500 feet below gage; shifts. 

EXTREMES OP DISCHARGE. Maximum mean daily discharge during year, 10,300

second-feet August 10; minimum mean daily stage, 3.24 feet July 28-29

(discharge, 32 second-feet, determined from extension of rating curve and

subject to error).

1920-1925: Maximum stage recorded, 12.85 feet at 1 a. m. June 8, 1921

(discharge, 22,000 second-feet, determined from extension of rating curve

and subject to error); minimum discharge, that of July 28-29, 1925.

In September, 1919, the river reached a stage of 26.4 feet (discharge not

determined).
EIO GRAJSDE BASIN 233

DIVEESIONS. The Carlsbad project of the United States Bureau of Eeclam ation 

with reservoirs having a capacity of 58,500 acre-feet, diverts a large part of 

' the natural run-off above Carlsbad, N. Mex. During season of irrigation 

considerable water is returned to the stream by seepage from lands near 

Carlsbad. In addition to water used by the Carlsbad project, some diversions 

are made for irrigation in the basin above the storage reservoirs of the Carlsbad project.

REGULATION. Operation of the water-power plant of 300-horsepower capacity 

above station, just below Carlsbad, It. Mex., owned and operated by Carlsbad Electric Light & Power Co., does not materially regulate flow at gage. 

The flow is, however, regulated to a large extent by waters stored in the reservoirs of the Carlsbad project. In the season of irrigation the effect of the 

regulation is decreased by return seepage water, but during the winter the 

flow depends on water released at the reservoirs.

ACCUEACY. Stage-discharge relation not permanent. Rating curve well defined 

above 100 second-feet. Operation of water-stage recorder satisfactory. Daily 

discharge determined by shifting-control method, averaging discharge for 

fractional parts of a day on days of considerable fluctuation. Records good.

COOPERATION. Records furnished by United States Bureau of Reclamation.

PECOS BIVEB NEAR AH6B&ES, TEK.

LOCATION. In T. 26 S., R. 29 E., just below Pecos Valley Railroad bridge crossing Delaware Creek at its mouth, 2 miles nortk of New Mexico-Texas 

State line, 8^£ miles northwest of Angeles, Reeves County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 27, 1914, to September 30, 1925.

GAGE. Stevens continuous water-stage recorder, at first outcropping of rock on 

right bank 600 feet below railroad bridge and mouth of Delaware Creek; 

inspected by Geological Survey engineers.

DISCHARGE MEASUREMENTS. Made by wading or from cable half a mile downstream.

CHANNEL AND CONTROL. Bed and banks composed of sand, gravel, and rock; 

banks not subject to overflow. Control formed by & series ©f rapids 200 feet 

below gage; shifts.

EXTREMES OP DISCHARGE. Maximum stage during year from water-stage recorder, 8.53 fee* at 10 a. m. August 10 (discharge, 12,700 second-feet, determined from extension of curve and subject to error). Minimum discharge, 

45 second-feet July 4 and 5.

1914-1925: Maximum stage recorded, 21.5 feet at 10 a. m. August 8,1916, 

measured by leveling from floodmarks (discharge not determined); mintmum discharge that of July 4 and 5, 1925.

ICE. Stage-discharge relation not seriously affected by ioe; open channel rating assumed applicable.

DIVERSIONS. The Carlsbad project of the United States Bureau of Reclamation, 

with reservoirs having a capacity of 58,500 acrerfeet, diverts a large part of 

the natural run-off above Carlsbad, N. Mex. During the season of irrigation 

considerable water is returned to the stream by seepage from lands near 

Carlsbad. In addition to the water used by the Carlsbad project some diversions are made for irrigation in the basin above the storage reservoir of the 

project.

REGULATION. Operation of a water-power plant of 300-horsepower capacity 

above station, just below Carlsbad, N. Mex., owned and operated by Carlsbad Electric Light & Power Co., does not materially regulate flow at gage. 

The flow is, however, regulated to a large extent by waters stored in the 

reservoirs of the Carlsbad project. In the season of irrigation, the effect of 

the regulation is decreased by return seepage waters, but during the winter, 

the flow depends on water released at the reservoirs.
RIO GRANDE BAJ3IN 235

ACCURACY. Stage-discharge relation not permanent. Standard rating curves 

well denned. Operation of water-stage recorder not satisfactory. Daily 

discharge determined by shifting-control method, averaging discharge for 

intervals of day on days of considerable fluctuation. Records fair.

20 second-feet July 25.

1922-1925: Same as given above.

DIVERSIONS. The Carlsbad project of the United States Bureau of Reclamation, 

which has reservoirs having a capacity of 58,500 acre-feet, diverts a large 

part of the natural run-off above Carlsbad, N. Mex. During the season 

of irrigation, considerable water is returned to stream by seepage from lands 

near Carlsbad. In addition to the water used by the Carlsbad project, 

some diversions are made for irrigation in the basin above the storage 

reservoir of the Carlsbad project.

REGULATION. Operation of a water-power plant of 300-horsepower capacity 

above station, just below Carlsbad, N. Mex., owned and operated by Carlsbad Electric Light & Power Co., does not materially regulate the flow at 

gage. The flow is, however, regulated to a large extent by waters stored in 

the reservoirs of the Carlsbad project. In the season of irrigation, the effect 

of the regulation is decreased by return seepage waters, but during the winter 

the flow depends on water released at the reservoirs.

ACCURACY. Stage-discharge relation not permanent. Rating curve well defined 

below 1,000 second-feet, fairly well defined between 1,000 and 4,500 secondfeet, and extended above. Gage read to hundredths once daily except 

Sundays. Daily discharge determined by shifting-control method. Discharge for approximately every seventh day interpolated. Records fair.

2S8 SURFACE WATER SUPPLY, 1925, PART VIII

PECOS SITES ABOVE BARSTOW, TEX.

LOCATION. 100 feet below dam and diversion of Barstow Canal (Ward County 

Irrigation District No. 1), and 10 miles northwest of Barstoiw, Ward County^

DBAINAGE AREA. Not measured.

RECORDS AVAILABLE. February 1, 1916, to May 11, 1921; March 22, 1922, toSeptember 30, 1925.

GAGE. Stevens continuous water-stage recorder on left bank; inspected by 

Geological Survey engineers. Gage used 1916-1921 was at & site 4 miles 

upstream.

DISCHARGE MEASUREMENTS. Made by wading, from cable near gage, or from 

Texas & Pacific Railway bridge near Pecos.

CHANNEL AND CONTROL. Channel straight for several hundred feet above and

below station. Bed composed of rock; permanent. Banks of silt and sand;

shift; subject to overflow at extremely high stages. Low-water control is

.. rock ledge, 150 feet below gage; permanent. Point of zero flow is 1.27

feet.

EXTREMES OP DISCHARGE. Maximum stage during year from water-stage 

recorder, 9.53 feet at 8.30 a. m. August 13 (discharge, 4,720 second-feet, 

determined from extension of rating curve and subject to considerable 

error); minimum stage, 1.39 feet April 23 (discharge, 0.3 second-foot).

1916-1925: Maximum stage recorded, 12.1 feet (by datum of former 

location) at 6 a. m. August 10, 1916 (discharge not determined); minimum 

discharge, 0.2 second-foot April 27-29, June 25 to July 10, July 13-20, 

and July 24 to August 21, 1923,

DIVERSIONS. In addition to water diverted in New Mexico by the Carlsbad 

project, the three principal diversions in Texas are the Farmers Independent, 

Cedarvale (formerly Biggs), and Barstow Canala. Small amounts diverted 

by Boxley and Porterville irrigation systems. According to records of the 

Board of Water Engineers for the State of Texas, these projects have declared 

a total of 17,500 acres irrigated.

REGULATION. Flow during low and medium stages regulated by storage reservoir on Carlsbad project in New Mexico and by diversion dams in Texas. 

Flood flow partly regulated by reservoirs on Carlsbad project.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined 

below 1,000 second-feet, fairly well defined between 1,000 and 3,500 secondfeet, and extended above. Operation of water-stage recorder not satisfactory. 

Daily discharge determined by applying to rating table mean daily gage 

height obtained from recorder graph by inspection or by averaging discharge 

for intervals of a day except as noted in footnote to daily-discharge table. 

Records fair.

Peeos River, 1J^ miles above present Grandfalls-Fort 

crossing at iron bridge, 2 miles below diversion dam for lowcaiial of Imperial Irrigation Co., 3 miles south of Grandfaljs, 

and 4J^ miles above diversion dam of Zimmerman project, 

Ndt measured.
240 SURFACE WATER SUPPLY, 1925, PART VIII

RECORDS AVAILABLE. November 6, 1915, to September 30, 1925. At iron 

bridge 1^ miles downstream from November 6, 1915, to August 3, 1917. 

Discharge at both points believed to be comparable.

GAGE. Stevens water-stage recorder on downstream side of old bridge pier 

near left bank; inspected by engineers of Geological Survey.

DISCHARGE MEASUREMENTS. Made by wading, from cable 50 feet above, or 

from iron bridge.

CHANNEL AND CONTROL. Bed rough, solid rock, and permanent, except for 

small deposits of sand and gravel. Channel straight for 100 feet above and 

below station. One channel below gage height of 8 feet; above this stage banks, 

which are of dirt and wooded, subject to overflow. Rock ledge extending 

diagonally across stream just below gage serves as low-water control; shifts, 

owing to clogging of crevices.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage 

recorder, 5.50 feet at 9 a. m. August 16 (discharge, 2,920 second-feet); 

minimum stage, 0.25 foot for several periods (discharge, 0.5 second-foot). 

1915-1925: Maximum stage recorded, 9.6 feet from 2 to 6 a. m. September 

25, 1919 (discharge, 13,000 second-feet); minimum discharge, 0.5 second-foot 

for several periods in 1925.

DIVERSIONS. Station is 2 miles below diversion of low-line (silt-line) canal of 

the Imperial Irrigation Co., 18^ miles below diversion for the Imperial 

Reservoir (17,000 acre-foot capacity), 25^ miles below diversion for Ward 

County Water Improvement District No. 2 (of which the old Grandfalls 

project is a part), and 4^ miles above diversion for Zimmerman project. 

Available data show that tracts aggregating approximately 143,000 acres 

are irrigable between station and lower limits of Carlsbad project of the 

United States Bureau of Reclamation. Records of the Board of Water 

Engineers for the State of Texas show that about 58,000 acres were declared 

irrigated in Texas above the station. The effect of diversions is somewhat 

counterbalanced by water returned to stream by seepage. The only important diversion below station is that for the Zimmerman project, which has 

declared an irrigated area of 2,005 acres.

REGULATION. Slight regulatory effect caused by operation of storage reservoirs 

on Carlsbad project.

ACCURACY. Stage-discharge relation not permanent. Rating curves well 

denned. Operation of water-stage recorder unsatisfactory during the later 

part of the year on account of improper attendance. Daily discharge 

determined by applying to rating table mean daily gage height determined 

from recorder graph by inspection or by use of planimeter, averaging discharge for intervals of a day on days of considerable fluctuation. Records 

fair.

PECOS RIVER NEAR SHEFFIELD, TEX.

LOCATION. At highway bridge on Fort Stockton-Ozona road^ miles east of

Sheffield, Pecos County. 

DRAINAGE AREA. Not measured. 

RECORDS AVAILABLE. October 10, 1921, to April 30, 1925, whea station was discontinued. 

GAGE. Chain gage attached to upstream side of bridge; road by Kyle Smith or

Leland Smith.

DISCHARGE MEASUREMENTS. Made from bridge or by wading. 

CHANNEL AND CONTROL. Bed of silt, sand, and gravel; shifts. Right bank

not subject to overflow; taft baak subject to overflow during extremely

high stages.

EXTREMES OF DISCHARGE. 1921-1925: Maximum stage recorded, 640 feet at 

> 8.30 a. m. October 20, 1923 (discharge, 2,460 second-feet). Minimum discharge, 15 second-feet at 6 p. m. August 15, 1923. 

DIVERSIONS. Station fo below all diversions. During much of the time, practically the only flow past the station is waste and seepage water from irrigated area above. 

REGULATION. Flow partly regulated by storage and diversion dam in New

Mexico and Texas. 

ACCURACY. Stage-discharge relation not permanent. Owing to badly shifting

control and poor gage-height record discharge is estimated from measurements

and by comparison with flow at other stations, and monthly discharge only

is considered sufficiently accurate to publish. Records fair.

PECOS RIVER NEAR COMSTOCE, TEX.

LOCATION.8 Pecos high bridge of Galveston, Harrisburg & San Antonio Railway, 12 miles northwest of Comstock,Val Verde. County, 5^4 miles above 

confluence with Rio Grande, and below all tributaries.

DRAINAGE ABBA. Not measured.

RECORDS AVAILABLE. May 1, 1900, to September 30, 1925. Also gage heights 

for 1898.

GAGE. Vertical staff attached to downstream side of bridge pier on left bank; 

read by J. R. Hutchins.

DISCHARGE MEASUREMENTS. Made from cable 1,000 feet above bridge.

CHANNEL AND CONTROL. Banks and bed composed of rock and gravel; water 

flows through a series of rapids and pools in a canyon about 300 feet deep. 

Banks not subject to overflow. Stage-discharge relation at low stages 

changes slightly.

EXTREMES OF DISCHARGE. Maximum stage during year, 23.6 feet at 1.30 a. m. 

May 28 (discharge, 65,000 second-feet, determined from extension of rating 

curve and subject to considerable error); minimum discharge, 134 secondfeet May 26.

1900-1925: Maximum stage recorded, 35.75 feet April 6, 1900 (discharge 

not determined); minimum discharge, 106 second-feet July 29 to August 1, 

1918.

DIVERSIONS. Considerable water is diverted and stored above station for 

irrigation. Lakes McMillan and Avalon of the Carlsbad project of the 

United States Bureau of Reclamation, with a combined capacity of 58,500 

acre-feet, are on Pecos River a few miles above Carlsbad, N. Mex. In addition to the water stored in New Mexico, water from Pecos River is used to 

irrigate large areas of land near Barstow and Grandfalls, Tex. No diversions 

below station. Return waters tend to equalize-effects1 of diversions in lower 

part of drainage basin.

REGULATION. Flow partly controlled by storage and diversions for irrigation 

above station. No water-power plants of any consequence operated in the 

drainage basin, except a public-utility plant of about 300 horsepower near 

Carlsbad, N. Mex.

ACCURACY. Stage-discharge relation not permanent. Rating curve well defined 

below 12,000 second-feet, poorly defined between 12,000 and 38,000 secondfeet, and extended above. Gage read to hundredths twice daily and oftener 

during floods. Daily discharge determined by shifting-control method. 

Records good.
