AUTHORIZATION AND SCOPE OF WORK

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

measurements of flow made on-; streams in the United States during 

the year ending September 30, 1922.

The data presented in these reports were collected by the United 

States Geological Survey under the following authority contained 

hi 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 hi 1886 in connection with special studies 

relating to irrigation hi the arid West. .Since the .fiscal year ending 

June 30, 1895, successive sundry civil biHs passed by Congress have 

carried the following item and appropriations: . r '

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 fesburces.

OF DATA ;. 

TheVdafca'JMresented in this report cover the year lyeginriing* Cfetober 1, 1921, attd 'ending September: 30, 1922, At the'^begiJlttijig of 

January in most parts of the United States much- of <the fMrecipita* 

tiOB! in the preceding three months is stored as ground* ^ater 'in* 1 the 

form of snow or ice, or in ponds, lakes, and swamps, and1 this stored 

water passes off in the streams during the spring. !breik-tfp. At the* 

end of "Septembery On the other hand, the only stored water available 

for- ran-off 'is possibly a small quantity in the ground; therefore the 

run-off 1 for' -the year beginning October 1 is practically all derived 

from precipitation within that 'Jtear . : ' , r i ; > ; - ( / : *

'The baMes: data' collected at ga'ging^ stations consist of records of 

stage,' measurements of discharge, and general information used to 

supplement the gage heights an!<$ discharge measurements in determining the daily flow. The records of 'stage are obtained-either from 

<lirect r.ea^ings on; a s^taff. gage or from a water-stage reporder,,tihat 

gives a continuous record of the fluctuations. Measurements o^f 

disdharge are made with -a current meter, (^fe H&Nli-'I!;) The 

general -metboids are outlined in 'standard textbopks on the measurefiient of' riTer discharge. ' : , ; ,

From the discharge measurements rating tables are prepared thftt 

give the discharge fof any stage. The application of the 'daily gage 

height to these rating tables gives the daily dischai^e from which 

the monthly 'and yearly meaa.-' discharge; is determinedt- > ' ' - ! ,- --' 

1 ' Tble data presented for each gaging 'stfttioi' in the-area: covered by 

this re|i6rt comprisei a description ;of the station, a table ^Mbag results 

of discharge measurements, ' a1 ttible showing the daily 'discharge of 

the stream? and-a ! table of mdnthly and yearly <fecharge ftnd'runnbff.

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

t&bles 'giving daily gage heights and results of: discharge 'measikre* 

mehtsr are published. ->"ii "" ' > '

The description of the station gives, in addition to statements 

regstrding iocfatioh and equipment, mformation in- regard to -any conditions that may affect the permanence of the sta^e-discharge i?ei&tionr 

covering stich subjects as the occurrence of icej^he use'of the^stnpeam 

fbt log 'driving, shifting of control, and the cause ;and effect of 

wa'ter; ; it fives' also 'hiformation as to diversions that 'decrease 

flow *at; the gage, artificial5 regulation, maximum' and m 

recorded stages, and* the twicuracy of the records* ; " ; , ;

secroljfd-fefet ^rtesponding to1 the mean of the gage heights read «ftch 

day. At stations ott1 streams subject to sudden or -rapid Carnal 

fiufctuation the: discharge obtained from the v *ofeing table and the 

me^an^^y g%g9 hei^bit may^.npt^be the (true :mean" discharge fOT'the 

day. If stich stations are equipped with water-stage reeordersi-ilhe
4 SURFACE WATER SUPPLY, 1922, PART VIII

mean daily discharge may be obtained by averaging discharge at 

regular, intervals during the day, or by using the discharge integrator, 

an instrument operating on the principle of the planimeter and con~ 

taining as an essential element the rating curve of the station.

In the table of monthly discharge th0 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 given in the maximum 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" is 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 

observation of stage, measurements of flow, and interpretation of 

records.

A paragraph in the, description of the station or footnotes adde,d 

to the tables 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.1

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

rating is probably accurate within 5 percent; "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 ,b^ 

subject to gross errors caused by the inclusion of large jnoncqn* r 

tributing districts in the measured drainage, area, by lack of infprr 

mation concerning water diverted for irrigation or other ,use,, or by 

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

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

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

probable. The computations are also omitted for stations on streamy 

draining areas in which the annual rainfall is less, than 20

All figures representing "second-feet per square mile" and "run-off 

'in inches" published by the survey in earlier reports should be used 

with caution because of possible inherent, sources of error not known 

to the survey..- - ' < 

Many gaging' stations on. streams-in the irrigated areas of the. 

United States are located above most of the Aversions 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 sati^fidd. 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 i$$a? of the 

flow at the station and should not be used for other than prehminary 

estimates; the tables of daily discharge allow mpre detailed studies 

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

the observations in each succeeding year may be expected to throw 

new light on data 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 investigations 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, buii some have 

appeared in the bulletins, professional papers, monographs, and 

annual reports.

The results of stream-flow measurements are now published annually in 12 parts, each part covering an area whose boundaries coincide 

with natural drainage features, as indicated below: i

14 SURFACE WATER SUPPLY, 1922, PART VIII

RECORDS AVAILABLE. October 1, 1920, to September 30,1922. Records of stage 

have been kept by United States Weather Bureau at Paddock viaduct since 

March 1, 1910.

GAGE. Gurley graph water-stage recorder, located in the old pump house of 

Fort Worth Power & Light Co.

DISCHARGE MEASUREMENTS. Made by wading, from highway bridge, 1,000 feet 

above gage, or from North Twelfth Street bridge, 2 miles below, gage.

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

below section. Right bank high, brushy, and not subject to overflow. Left 

bank low, with a protection levee, but subject to overflow at high stages. 

Bed composed of rock, gravel, and clay. Control is a concrete dam just 

below gage and is permanent.

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

recorder, 23.95 feet at 12.20 p. m. April 25 (discharge, 85,000 second-feet, 

determined as follows for Clear Fork of Trinity: By city of Fort Worth 

engineers by slope method using Kutter's formula. Average hydraulic 

factors from six cross sections between JMarys Creek and Frisco railroad 

bridge. A= 17,700 square feet; P=2,449 feet; R=7.2 feet; n=0.055; 

s=0.0015; v=4.2 feet per second; Q = 74,340 second-feet. Discharge for 

West Fork of Trinity River at Lake Worth dam determined by formula, 

Q=3.33 LH3/2, H=26 inches, Q=8,100 second-feet. Inflow between gage 

and points measured estimated a.t 2,500 second-feet.) Minimum stage, 

0.92 foot, December 6, determined by comparison with Weather Bureau 

gage and subject to error (discharge, 1.'4 second-feet).

1910-1922: Maximum stage that of April 25, 1922. (This is the highest 

stage at this point of which there is any authentic record). No flow during 

several periods of record.

ICE. -None during year. . ,. . ...

DIVERSIONS. The city of Fort Worth diverts for municipal use about 15 secondfeet from the storage reservoir on the West Fork, known as Lake Worth.

REGULATION. Flow is partly regulated by. the storage at Lake Worth, which has 

a capacity of about 30,000 acre-feet.

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

from 0 to 14,000 second-feet and extended to cover range of stage by use of 

one slope measurement at gage height of 23.95 feet (see footnote to discharge 

measurements). 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 use of planimeter, except 

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

TBINITY BIVEK AT D All AS, TEX.

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

below Texas & Pacific Railway bridge, one block fr<5m county courthouse 

one block upstream from union station, 3 miles by air line and 5 miles by 

river below confluence of Elm Fork and West Fork of Trinity River.

DKAINAGE ABE A. 5,920 square mites (measured on standard topographic maps; 

post-route maps; and topographic map of Texas, compiled in 1899 bjr 

Robert T. Hill, of the United States Geological Survey; scale, 1 inch=25 

miles).

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

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

September 30, 1922. Gage readings by United States Weather Bureau 

available since 1903.

GAGE. Chain gage attached to downstream handrail of Commerce Street 

viaduct; read by C. J. Anderson. From October 1, 1898, to December 31, 

1899, gage was at Turtle Creek pumping plant, 2 miles above present gage. 

Relation between gages not known.

DISCHABGE MEASUREMENTS. Made by wading, from upstream side of Commerce Street viaduct, or from "Millers Ferry" bridge about 6 miles downstream from gage.

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

and 600 feet below station. Right bank medium in height, composed of 

clay and gravel, wooded and subject to overflow, left bank high, fairly 

clean, and not subject to overflow except at extremely high stages. Bed 

is composed of clay and gravel and is fairly permanent. Low-water control 

is a 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, 

seldom occurs. ;

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 42.35 feet 

at 5.15 a. m. April 27 (discharge, 75,100 second-feet); minimum stage, 4.32 

feet at 4.30 p. m. September 8 (discharge, 19 second-feet).

1898-99; 1903-1906; 1921-22: Maximum stage that of April 27, 1922; 

minimum stage that of September 8, 1922.

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 1917-18 discharge was practically zero.

ICE. None reported during year.

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

of importance above.

REGULATION. Low-water flow is partly regulated by municipal dams oa.Wes't 

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

AccuRACY.-rrStage-discharge relation permanent. Rating curve well define*! 

from 20 to 75,000 second-feet. Gage read to hundredths twice d«$l#, 

except as follows: February 18 to 21, Weather Bureau gage-height recordte 

of one reading daily used; April 5, seven readings used; April 25, five 

ings used, April 26, 19 readings used; and April 27, seven readings 

Daily discharge determined by applying mean daily gage height to rating 

table. Records good. - ...

a small percentage of the total run-off during years of ordinary flow.

REGULATION. Flow regulated during extremely low stages by, 'city of Dallas 

reservoir at Carrolltpn.

ACCUBACY. Stage-discharge relation permanent, except when affected .bybackwater from Trinity River. Rating curve well defined below 1,100 

. second-feet, and fairly well defined from 6,200 to 16,000 second-feet. Nomeasurements between 1,100 and 6,200 second-feet, and this portion of 

rating may be slightly in error. Gage read to. hundredths twice daily and 

oftener during floods. Daily discharge determined by applying mean daily 

gage height to rating table, except as noted in footnote to daily-discharge 

table. Records fair. . :

United States Weather Bureau since August 9, 1900.

GAGE. Gurley graph water-stage recorder' installed March 29, 1918, on downstream side of pier df Southern Traction Co.'s bridge, 100 feet upstream 

from suspension bridge; Inspected by H. E. Isaacks. For history of gages 

, used prior to March 29, 1918, see Water-Supply Paper 508, page 12.

DISCHARGE MEASUREMENTS. Made from upstream side of first one-span highway bridge above gage or by wading.

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

clay, medium in height, have been improved by the city, and are overflowed at extremely high stages. Channel straight above and below for 

several thousand feet. Location of control not known.

EXTREMES OF DISCHARGE. Maximum stage recorded during the year, 35.9 feet 

at 2 a. m. May 10 (discharge, 122,000 second-feet); minimum discharge, 50 

second-feet at 11 a. m. March 23.

May 6 to September 30 when United States Weather Bureau record of dfie 

reading daily to tenths was used, except for May 10, 11, 12, and 23, when 

several readings were made. October 1 to May 5, mean daily gage heights 

obtained from recorder graph by inspection, or by use of pianimeter. Daily 

discharge determined by indirect method for shifting control, except as noted 

in footnote to daily discharge table. Records fair.

LOCATION. At Jones Bridge, 4 miles below Munson Shoals, 6 miles southwest of 

College Station, Brazos County, 19 miles above mouth of Yegua River, and 

30 miles above mouth of Navaseta River,

DRAINAGE ABEA. 35,400 square miles (measured on standard topographic maps; 

, post-route map; »nd topographic .map of; Texas, compiled in 1899 by Robert 

: T. Hill, of United States Geological Survey; scale, linch=25 miles).

BfccoBDs AVAILABLE- February 23, 1918, to September 30, 1922; ,

GAGE. Standard chain gage on upstream luandrail of bridge installed April 18, 

1922; read by Lamar McRae. Gage from February 23, 1918, to April 17, 

1922, was vertical staff in'two sections on>. fourth pie.r froin'right bank. 

Section 0 to 14 feet was attached to sheet' piling around footing- of pier. 

Section 14 to 52 feet was painted on same pier. . r

DISCHABGE MEASUREMENTS. Made from bridge to which gage is attjached.

CHANNEL AND CONTBOL. Bed composed of sand -and mud; shifting. Location 

of control not known. Banks high and free from vegetation. Right bank 

subject to overflow at extremely high stages (about 40 feet).

EXTBEMES OP DISCHABGB. Maximum stage rec'orded, during year, 49.0 feet 7 

a. m. April 6 to 7 a. m. April 7 (discharge, 121,000 second-feet); minimum 

stage, 5.6 feet March 21-24 (discharge, 380 second-feet, subject to error 

owing to inability of observer to read gage accurately). .

1918-1922: Maximum stage recorded, 53.0 feet, 1 to 3 a. m. September 12, 

1921 (discharge not determined); minimum stage, 3.75 feet September 4, 

1918 (discharge, 92, second-feet).

ICE. None reported during year. '"

DIVEBSIONS. No important diversions above or below station.

REGULATION. None. A lock and dam is being constructed by the War Department about 25 miles upstream, which may eventually regulate the flow during 

extremely low stages.

ACCUBACY. Stage-discharge relation not permanent. Rating curve well de-

, fined below 40,000 second-feet, and poorly defined fpm 40,000 to 114,000 

second-feet. Gage read to tenths twice daily. Daily discharge determined 

by indirect method for shifting control, except as noted in footnote to dailydischarge table. Records fair.

COLORADO RIVER AT BAI1IN01R, TEX.

LOCATION. At Hutehitts Avenue highway bridge, 800 feet below Gulf, Colorado 

& Santa Fe Railway bridge at Ballinger, Runnels County, 1 mile above 

mouth of Elm Creek.

DRAINAGE ABBA. 12,500 square,miles (revised; measured on standard topographic maps; post-route map; and topographic map of Texas, compiled 

in 1899 by Robert T. Hill, of United States Geological Survey; scale, 1 inch= 

25 miles).

RECORDS AVAILABLE. December 1,1, 1915, to September 30, 1922. Records 

of stage have been obtained by the United States Weather Bureau since 

July 1, 1903; current-^meter measurements were begun May 29, 1915.

GAGE. Chain gage attached to downstream handrail of bridge; read by A. J. 

Voelkel. Zero of gage-lowered 1 foot on May 4, 1921. ,'!

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by 

wading. , CHANNEL AND CONTROL, 'Banks consist of clay and gravel; medium height and 

wooded; subject to overflow at extremely high stages. Bed coniposed of 

hard clay, sand, and gravel; shifting. Control is shoal 1,000 feet below 

gage.; subject to change. . .

ICE. None reported during, year.. ' ;-

EXTREMES or DISCHARGE. Maximum stage recorded during year, 26.0 feet", 

during night of April 26 (discharge, about 28,000 second-feet, determined 

from extension of rating curve and subject to large error). No flow October 

r 1 to November 30, Mairch 7^-24, an4 April 18-23. .

1916-1922: Maximum stage recorded that of April 26, 1922; no flow 

during several periods. »

DIVERSIONS: During/low $tajfe$ a large part of the flow is diverted & few miles 

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

for the. State of Texas show that about 6,000: acjes1 have been declared irrip 

gated above the station.

REGTTLATION. None of consequence.

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

defined from 0 to 16,000 second-feet. Gage read to. Imndredths twice daily. 

Daily discharge determined by indirect method for shifting control, except 

from April 3 to August 9, when daily mean gage height was applied to 

rating table and as noted in footnote to daily-discharge table. Records 

poor. ,

COLORADO RIVER HEAR CHADWKJK, TIX.

LOCATION. At Gutf, Cotofadb &'Sahta f^s 'HattWay brttfee ow

Chadwick dam, 1 mile above mouth of Elliott Creek, 2 miles west of Chadwick, on line between San Saba and Lampasas counties, and 2^j miles 

 below mouth of San Saba River.
COLORADO RIVER BASIN 29

DRAINAGE ABBA. 26>400 square miles (measured on standard topographic 

maps; post-route map; and topographic map of Texas, compiled in 1899 by 

Robert T. Hill, of the United States Geological Survey; scale, 1 inch=25 

miles).

RECORDS AVAILABLE. October 21, 1915, to October 31, 1922, when station was 

discontinued.

GAGE. Vertical and inclined staff, in four sections on right bank, 75 feet upstream 

from railway bridged A high-water section is painted on second concrete 

pier from left abutment of railway bridge; read by A. G. Walker. For 

history of gages used prior to April 1, 1920, see Water-Supply Paper 508, 

page 28.

DISCHARGE MEASXJKEMENTS. Made either by wading or from railroad bridge 

at gage, or from Red Bluff highway bridge, 2J^ miles below gage.

CHANNEL AND CONTKOL. Bed composed of rock and gravel; shifts slightly. 

Channel straight above and below station for 1,000 feet. Left bank high, 

rocky, wooded, and not subject to overflow; right bank medium in height, 

wooded, composed of clay and gravel, and subject to overflow during extreme 

stages. Location of control not known, but current-meter measurements 

indicate that it shifts; affects stage-discharge relation at low stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 51.5 feet 

at 3 p. m. April 26 (discharge not determined); minimum stage, 0.70 foot 

November 20 and 21 (discharge, 45 second-feet)*

1916-1922: Maximum stage recorded that of April 26, 1922; "minimum 

stage, 0.16 foot August 22 and 23, 1918 (discharge, 1.5 second-feet).

ICE. None reported during year.

DIVEESIONS. No large irrigation works have been completed in drainage basin 

above station, but tracts ranging in size from 5. to 1,500 acres adjacent to 

the main river and tributaries are irrigated by diversions. A large part of 

the irrigated area is in Runnels, Brown, and Mills counties and along Concho 

and San Saba rivers. Several small dams have been constructed in the 

drainage basin above station. Chadwick dam half a mile above creates 

a small pond and serves only to divert to a water wheel that has not been 

operated for some time. Records of the Board of Water Engineers for the 

State of Texas show that about 30,000 acres have been declared irrigated 

above the station.

REGULATION. None of consequence, except possibly during extremely low 

stages.

ACCURACY. Stage-discharge relation not permanent for low stages, but not 

seriously affected during medium or high stages. Rating curve well defined below 80,000 second-feet. Gage ordinarily read daily to hundredths 

during low and medium stages, and to tenths during high stages, but observer's readings subject to error. One reading a day may not be/ true 

- index to discharge, owing to rapid fluctuations. Daily discharge determined 

by indirect method for shifting control during low stages and by applying 

gage heights to rating table for medium and high stages, except as noted in 

footnote to daily-discharge table. Records poor. v . . -'!

COLORADO RIVER BASIN 31 

COLORADO RIVER AT MARBLE FALLS, TEX.

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

Burnet County, 10 miles below mouth of Sandy Creek, 16 miles below 

mouth of Llano River, and 23 miles above mouth of Pedernales River.

DRAINAGE AREA. 32,200 square miles (measured on topographic and post- 

. route maps.)

RECORDS AVAILABLE. October 1, 1916, to September 30, 1022. Miscellaneous 

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

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

GAGE. United States Weather Bureau weight-and-tape gage on upstream side of 

bridge; read by M. M. Galloway.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of solid rock. Bank composed of 

rock, gravel, and clay; wooded, high, and not subject to overflow. Rapids 

just below gage serve as fairly permanent control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 22.3 feet at 

about 1 p. m. May 1 (discharge not determined); maximum stage, 1.10feet 

at 7.30 a. m. October 30 and 31, and 7.30 a. m. to 5.30 p. m. November 20; 

(discharge, 63 secotfd-feet, subject to error owing to influence of wind 

on tape).

1900-1922: Maximum stage,4 23.9 feet April 7, 1900 (discharge not 

determined); no flow August 7, 8, 11-25, 1918, caused by storing water 

above gage. .

ICE. None.

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

above station, but none has been developed. Numerous small diversions 

for irrigation and municipal uses are made above the 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 not permknent. Rating curve well 

defined from 0 to 4,000 second-feet and only fairly well defined above, owing 

to inability to read gage accurately, on account of surge and high velocities. 

Gage read to hundredths twice daily, though influence of wind on tape and 

surge of water at high stages may introduce some error. Daily discharge 

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

October 1 to April 3 when indirect method for shifting control was used 

and June 11 to July 19 when there was no record. Records good for low 

stages and poor for high stages.

The following discharge measurement was made by Ellsworth and Dudley: 

November 21, 1921: Gage height, 1.50 feet; discharge, 132 second-feet.

COLORADO RIVER AT AUSTIN, TEX,

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

half a mile below Shoal Creek and above mouth of Waller Creek, 1 mile 

below mouth of Barton Creek, and 3J^ miles below Austin dam.

DBAINAGE AKEA. 34,200 square miles (measured on standard topographic maps; 

post-route map; and topographic map of Texas compiled in 1899 by Robert 

T. Hill, of the United States Geological Survey; scale, 1 inch = 25 miles).
COLORADO EIVEE BASIN 33

RECOBDS AVAILABLE. February 15, 1898, to September 30, 1922. Records of 

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

1903. See footnote to monthly-discharge table.

GAGE. Stevens water-stage recorder installed April 26, 1918, on downstream 

side of pier of viaduct; inspected by engineers of United Slates Geological 

Survey. Record of depth of water on crest of dam, 3^ miles above Austin, 

was kept August 13, 1895, to April 7, 1900. Gage used February 15, 1898, 

to December 31,1911,wasa vertical staff attached to bathhouse on left bank of 

river 150 feet above Congress Avenue Bridge; during this peiiod high-stage 

readings were made by means of a gage painted on first pier from left end of 

bridge and a chain gage attached to bridge. From January 1, 1912, to 

June 18, 1915, the vertical gage of United States Weather Bureau was read. 

Record from June 18, 1915, to April 25, 1918, was obtained by means of 

Dexter water-stage recorder installed at end of viaduct. All gages at or 

near bridge have been referred to same datum. '

DISCHABGE MEASUBEMENTS. 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 of medium height, composed of clay and gravel 

clean, improved by city, and subject to overflow; left bank resembles right 

bank, except that it is high and nearly vertical in places. Bed clean and 

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

shoal 500 feet below gage; changes during high water and also during low 

water because of removal of sand for municipal use.

EXTBEMES OF DISCHABGE. Maximum stage from water-stage recorder, 22.6 feet 

at 11 p. m. May 1 (discharge, 120,000 second-feet); minimum stage, 0.42 foot 

at 5 p. m. March 22 (discharge, 135 second-feet).

1898-1922: Maximum stage recorded, 33.5 feet a few minutes after the 

failure of the 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 time of failure the depth of water over the crest 

of the dam was 11.07 feet, the computed discharge being 151,000 second-feet 

(a revision of previously published discharge). According to information 

obtainedv from persons living near Congress Avenue Bridge, the stage rose 

6.1 feet as a result of failure of dam. From this, the gage height corresponding to a discharge of 151,000 second-feet was 27.4 feet. According to 

Mr. W. P. Johnson, who was in charge of the power plant at the dam, the 

flood appeared to be practically at crest stage when the dam failed. Minimum stage, 0.18 foot at 6 p. m, August 18, 1918 (discharge, 13.0 secondfeet).

ICE. None during year.

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 the Austin 

dam, about 3J^ miles upstream. Neither sluice gates, crest gates, nor 

power plant at the dam were in operation during the years endiag September 

30, 1919-1922. Capacity of reservoir about 24,000 acre-feet.
34 SURFACE WATER SUPPLY, 1922, PART VIII

ACCURACY. Stage-discharge relation not perpaanent. -Numerous measurements; 

made throughout the year. Curve well defined for all stages. Operation of 

water-stage recorder satisfactory except for short breaks in record as noted 

in footnote to daily-discharge table. Mean daily gage height obtained from 

water-stage recorder chart by inspection or by use of planimeter. Daily 

discharge ascertained by indirect method for shiting control, except as noted 

in footnote to daily discharge table. Records'good.

From recent information it is thought that the discharge as published in 

Water-Supply Paper 408 for December 13-26, 1914, and February 9-17, 

1915, is too low. Discharge on those days probably exceeded 20 secondfeet. See also footnote to monthly-discharge table.

NOTE Discharge records prior to Jan. 1,1912, have been revised, as more information is now available 

than when first published- Discharge records from Jan. 1,1911, to Sept. 30,1914, not previously published 

have been computed from gage records furnished by the United States Weather Bureau, using tstiw 

curve based on discharge measurements made during 1910,1914, and 1915. All daily-discharge figures and 

some minimum monthly-discharge figures prior to Sept. 30, 1914, have been withheld because of probability of large errors, due to changes in stage-discharge relation and insufficient discharge measurements. 

Such figures published in earlier reports should be used with caution. Records herewith published prior 

to Sept. 30,1914, are considered fairly accurate, except during low stages when gross errors may be expected, 

particularly during the years 1906-J.909 and 1911-1914 when no discharge measurements were made, except 

a series of high-stage measurements in June, 1906. Monthly-discharge records from October, 1914, to 

September, 1921, are the same as those published In previous reports, and are considered reliable.

COIOEADO RIVER AT COIUMBUS, TEX. '

LOCATION. At county highway bridge half a block from county jail and 400 

feet below Galveston, Harrisburg & San Antonio Eailway bridge, in eastern 

edge of Columbus, Colorado County.

DKAINAGE AKEA. 37,000 square miles (measured on standard topographic maps; 

post-route map; and topographic map of Texas v compiled in 1899 by Robert 

T. Hill, of the United States Geological Survey; scale, 1 inch = 25 miles).

RECORDS AVAILABLE. August 2> 1902, to December 31,,1911> May 22, 1916, to 

September 30, 1922. Records of stage have been obtained by the United 

States Weather Bureau since, January 1, 1903 4 ,,

GAGE. Gurley graph water-stage recorder, inspected by J, H. Hastedt or L. 

Hastedt. From August 2, 1902, to December 16, 1907,, gage heights were 

obtained by measuring with a tagged chain and,lead weight from point on 

top of bridge pier to water surface. Mott tape-and-weigh^ gage on downstream handrail of bridge, property of the United States Weather Bureau, 

was read from December 17, 1907, to February 9, 1917, when regulation 

United States Geological Survey chain gage was installed and uged until 

April 30,19-19', when present G«rley water-stage, reqprder was installed., 

All gages referred to same datum.

DISCHARGE MEASUREMENTS. Made from upstream side of bridge or by wading.

CHANNEL AND CONTROL. Channel straight above and below station for 400 feet. 

Right bank composed of firm earth; high and not subject to overflow. 

Left bank of medium height; subject to overflow above a gage height of 3,4 

feet. Bed of stream clean and sandy; shifts. A sand and gravel section 350 

feet below gage may serve as low-water control; the stage-discharge relation 

during medium and high stages may be controlled by a bend in river below 

bridge.
COLORADO MVER BASIN

EXTREMES' or DISCHARGE. Maximum stage during year from water-stage recorder, 38.3 feet 3 p. m. May 5 (discharge, 79,500 second-feet, determined 

from extension of rating curve and subject to error); minimum stage, 5.49 

feet at 1 p. m. December 23 (discharge, 348 second-feet).

1902-1911; 1916-1922: Maximum stage recorded, that of May 5, 1922; 

minimum stage, 4.2 feet September 9 and 10, 1910 (discharge,.. 10 second- 

 feet). : ' ; ;../.

ICE. None reported during year:

DIVERSIONS. Considerable water is diverted for irrigation in the drainage basin 

above Austin,, but little w^ater is diverted between Austin ap|d Columbus. 

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

acres. Records of 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. Two rating curves used. 

One from October 1 to April 27 well defined below 55,000 second-feet, and 

one from April 28 to September 30, fairly well defined below 65,000 secondfeet.. Operation of water-stage recorder not satisfactory. Daily gage 

heights obtained from recorder chart by inspection or by planimeter, except 

as noted in footnote to daily-discharge table. Daily discharge ascertained 

by indirect method for shifting control, except April 28 to September 30, 

when mean daily gage heights were applied to rating table. Records poor.

COOPERATION. Record of gage heights furnished by United States Weather 

Bureau from August 20 to September 30.

M -v,, COLORADO RIVER AT WHARTOH, TEX.

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

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

DRAINAGE ABBA. 37,400 square miles (measured on standard topographic maps; 

post-route map; and topographic map of Texas, compiled in 1899 by Robert 

T. Hill, of the United States Geological Survey; scale, 1 inch=25 miles).

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

July 11 to August 4, 1918; and March 19, 1919, to September 30, 1922.

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

near left bank, installed March 19, 1919., Prior to March 19, 1919, vertical 

staff on right bank 75 feet below bridge. Zero of this gage 1.93 feet higher 

than zero of recorder. Temporary chain gage at same datum as recorder 

attached to downstream guardrail of same bridge from July 18 to October 

11, 1921.

DISCHARGE MEASUREMENTS. Made from highway or 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; shifting. Banks medium; 

in height, composed of clay, and subject to overflow during extreme 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 stages.

EXTREMES OP DISCHARGE. Ma'ximum stage recorded during year, 40.7 feet 

from 9 a. m. to 6 p. m. May 6 (discharge not determined); minimum stage, 

5.67 feet at 10 p. m. March 24 (discharge, 472 second-feet, ascertained from 

extension of rating curve and subject to error).

1916-1922: Maximum stage recorded during periods of record, that of 

May 6, 1922; minimum stage, 4.35 feet at 12.46 p. m. August 27, 1921 

(discharge, 45 second-feet ascertained from extension of rating curve and 

subject to error).

ICE. None reported..

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 diversion below Wharton. During periods of maximum demands, 

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

stage.

REGULATION. Flow at low and medium stages is regulated to some extent by 

storage in Lake Austin at Austin, Tex.

ACCURACY. Stage-discharge relation not permanent. Rating curve well defined from 500 to 15,000 second-feet, and fairly well defined to 30,000 secondfeet. Above this discharge, from extension of rating curve and subject to 

considerable error. See also "Channel and control." Operation of waterstage recorder from December 13 to September 30, satisfactory, except for 

short breaks in record as indicated ja footnote to daily-discharge table. 

From October 1 to December 12, recorder not working and staff gage read 

to hundredths once daily, and oftener during floods. December 18 to September 30 mean daily gage height determined from recorder graph by inspection 

or by planimeter. Daily discharge ascertained by indirect method for 

shifting control, except as noted in footnote to daily-discharge table. Records good except at extremely high and low stages.

NORTH CONCHO EIVEE AT SAN ANGEIO, TEX.

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

mile above confluence of North Concho and Sputh Concho- rivets.

DRAINAGE AREA, 1,520 square miles (revised; measured on post-route map and 

topographic map of Texas, compiled in 1899 by Robert T. Hill, of the United 

States Geological Survey; scale, 1 inch=25 miles)..

RECORDS AVAILABLE. October 27, 1915, to September 30, 1922.

GAGE. Steyens continuous water-stage recorder, attached to left side of web-of 

third pier of viaduct from left bank, installed September 1, 1920; inspected 

. by B. W. Wynn. Prior to this date vertical staff attached to same pier 

was used. Both recorder and staff gage referred to same datum, . DISCHARGE MEASUREMENTS. Made from second highway bridge upstream from 

gage or by wading 400 feet below.

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

covered in high-water channel with grass and moss; permanent. Channel 

straight for 800 feet above and 400 feet below gage. Banks are sloping", 

clean, composed of rock and clay, and not subject to overflow except during 

high floods. About 20 feet below gage and at downstream side of viaduct 

is a concrete dam about 4J^ 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->diseharge relation. Backwater 

probably occurs at this station when the Concho reaches a stage of 25 feet,

EXTREMES OP DISCHARGE. Maximum stage for the year from5 water-stage 

recorder, 19.3 feet at 7.30 p. m. April 26 (discharge, not determined. Backwater from Concho River probably existed during this stage); no flow 

October 1 to April 2, August 6 to September 18, and September 24-30.

1916-1922: Maximum stage recorded that of April 26, 1922; no flow for 

several periods during record.

ICE. None reported during year.

DIVERSIONS. Records 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. '""!' 
SURFACE WAEEB SUPPLY, 1922, t*AET

ACCUBACY. Stage-discharge relation permanent, except during periods of backwater. Rating curve well defined below 125 second-feet, and extended to 

7,400 second-feet by use of formula, Q=CLH^, for broad-crested weirsr 

using a value of 2.20 for C and may be considerably in error. Operation of 

water-stage recorder satisfactory. Daily discharge determined by applying 

to rating table mean c^aily gage height obtained from recorder graph by 

inspection, or by use of planimeter, except as noted in footnote 'to daily 

. discharge table. Records good, except at extremely low or high stages, 

 when subject to large errors.

NOTE. Owing to incomplete record, discharge partly estimated Apr. 13-18, July 8,13,17-31, and Aug. 1. 

Discharge determined by averaging discharge for fractional parts of a day Apr. 3, 9, 10, 26, 29, May 3, 4, 

14-21, 29, June 3, 5, 6,17, 18, 21, 30, July 1-6, and Sept. 19-21. Discharge interpolated July 9-12. Stage 

beyond limits of rating curve and discharge not determined; backwater probably existed as follows; Apr. 

26, 7.2 feet, and Apr. 27,6.4 feet. Backwater probably existed, amount unknown, on Apr. 8,24,28, May 1 

and 2. No flow Get. 1 to Apr. 2, Aug. 6 to Sept. 18, and Sept. 24-30.

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

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

DRAINAGE ABBA. 4,780 square miles (revised; measured on st&ndard topographic maps; post-route map; and topographic map of Texas, compiled in 

1899 by Robert T. Hill, of the United States Geological Slarvey; scale, 1 

inch=25 miles). '

RECORDS AVAILABLE. September 17, 1915, to September 30, 192:2. : GAGE. Stevens continuous water-stage recorder; installed August 9, 1917, on 

right bank, 1,500 fe«t below an old ford; inspected by B; W. Wynn. Prior 

to August 9, 1917, a-Vertical staff, gage in several sections attached to trees 

on left bank was used^ Water-stage recorder and vertical staff gage referred, 

to same datum. <

DISCHARGE MEASUREMENTS. Made by wading or from cable near gage.

CHANNEL AND coNTRoi+^-Bed .composed of solid rock and gravel. Channel 

straight for 1,000 feet above and below station. Right bank high, rocky, 

wooded, and not subject to-overflow; left bank of medium height, composed 

of clay and gravel, covered with scattered growth of/trees, and subject to 

overflow at high stages. Rapids just below gage serve as control for medium 

and low stages, but affected by moss. Location of control for high stages 

not known. .

EXTREMES OF DISCHARGE. Maximum stage for the year determined by leveling, 

36.8 feet April 26 (clischarge, not determined); no flow November 29.

1915-1922: Maximum stage, that of April 26, 1922; no flow November 

29, 1922.

ICE. None recorded during year.

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

About a mile above mouth of South Concho River, a storage dam has been 

constructed by the San Angelo Light & Power Co. for waterworks. 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 the dam of the San Angelo Light & Power Co. has 

slight effect on flbw at station; no regulation of consequence on North 

Concho River.

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

below 800 second-feet; above, it was determined by JU/d method, based on 

one measurement on July 8, 1919, at discharge of 40,'500 second-feet and a 

stage of 26.6 feet, u'sirig Kutter's formula with the value of n=0.045 and 

may be considerably in error. Operation of water-stage recorder not 

satisfactory as shown in footnote to daily-discharge table. Daily discharge 

ascertained by applying to rating table mean daily gage height, obtained 

from recorder graph by inspection or for days of considerable fluctuation 

by use of planimeter, except as noted in footnote to daily-discharge ti^ble. 

Records fair.

CONCHO RIVER NEAR PAINT ROCK, TEX.

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

mile below mouth of Kickapoo Creek and 2 miles northwest of Paint Rock, 

Conoho County. , ,
C.O!jORADO BT7EB BASIN. '51

DRAINAGE AEEA:-7-S,7SO square miles (revised; measured on standard topographic 

maps; post-route jnap; and topographic map of Texas, compiled in 1899 

by Robert T. Hill, .of'the United States Geological Survey; scale, 1 mch=25 

. miles). ,, ,(

RECORDS AVAILABLE. September 20, 1915, to September 30, 1922.

GAGE.* Stevens continuous water-stage recorder attached to downstream end 

of middle railroad bridge pier was installed September 16, 1920; inspected by 

engineers of the United States Geological Survey and by .N. N. Skaggs. 

Prior to September 16, 1920, gage was vertical staff attached to same pier.

DISCHARGE MEASUREMENTS. -Made by wading or from downstream side of 

bridge.

CHANNEL AND CONTROL.' Bed composed of solid rock, smooth, clean, free from 

vegetation, and permanent. Channel straight for 500 feet above and below 

gage. Right bank 30 feet high, solid rock, clear*, and not subject to overflow; left bank of medium height, sloping, wooded, and subject to overflow 

during high water. Permanent control during low and medium stages at a 

shoal in solid rock, 400 feet below gage. ;

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 27.5 feet at 

11 a. m. April 27 (discharge, not determined);, no flow October 13-17, 

October 30 to November 13, and August 23 to September 18.

1915-1922: Maximum stage recorded, that of April 27, 1922. The maximum stage previously recorded was 13.5 feet at 7.30 a. m. June 10, 1919 

(discharge, 20,700 second-feet, revised in 1922); no flow during several 

periods of every year except 1920 and 1921.

ICE. None reported during year.

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

show that about 11,000 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.

REGULATIONS^ Ten storage dams of small capacity are. located between this 

station and San Angelo. An abandoned dam, 12 feet In height, known as 

Fourmile 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 affects the flow by storing water, except 

during extremely low stages.

AccuRACY.-'-Stage-disehaTge* relation permanent. Rating curve well defined 

below 6,000 second-feet and poorly denned to 19,000 second-feet. Operation 

of water-stage recorder not satisfactory as shown in footnote to dailydischarge table. Daily discharge ascertained by applying to rating table 

mean daily gage height obtained from recorder graph by inspection or by 

use of planimeter, except as noted in footnote to daily-discharge table. 

Records good, except for extremely high stages.

COLORADO RIVER BASIN

SAN SABA RIVER AT MBNABD, TBX.

LOCATION. At steel highway bridge in Menard, Menard County, 80 miles above 

mouth of stream.

DRAINAGE AREA. 1,140 square miles (measured on standard topographic maps; 

post-route map; and topographic map of Texas, compiled in 1899 by Robert 

T. Hill, of the United States Geological Survey; scale, 1 inch**25 miles).

RECORDS AVAILABLE. September 14, 1915, to September 30, 1922.

GAGE. Chain gage attached to floor on downstream side of highway bridge; 

read by B. B. Burke or Haskell Howell.

DISCHARGE MEASUREMENTS. Made by wading or from downstream side of 

bridge.

CHANNEL AND CONTROL. Channel straight 800 feet above and 100 feet below 

station; somewhat obstructed by reeds and grass; water flows through a 

series of shoals and ponds; right bank composed of gravel and clay, wooded, 

sloping, high, and not subject to overflow; left bank similar in material, 

wooded, low, and subject to overflow. A sand and gravel ford just below 

gage forms a control during low stages; shifts.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 12.4 feet at 

10.30 a. m. April 26 (discharge not determined. Observer reports higher 

stage during afternoon of April 26 and 27 but heights not known). Minimum 

stage, 1.62 feet March 16-18 and 21-26 (discharge, 1.6 second^eet). Gage 

heights not comparable, owing to shifting control.

1915-1922: Maximum stage recorded, 13.6 feet at 2.30 a. m. September 

16, 1915 (discharge not determined); no flow July 12-14, 19-31, August 

1-4, and 26-31, 1918.

ICE. None reported.

DIVERSIONS. Considerable land is irrigated with watdr diverted above station. 

Noyes canal on right side Qf river which serves a considerable area diverts a 

short distance above gage. Records of the Board of Water Engineers for the 

State of Texas show that about 4,300 acres have been declared irrigated by 

diversions above the station, and about 7,700 acres by diversions below the 

station.

REGULATION. Flow unregulated by storage or water-power plants but is largely 

controlled at low stages during irrigation season by diversion to Noyes 

canal.

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

defined from 0 to 250 second-feet. Gage read to hundredths twice daily. 

Daily discharge determined by indirect method for shifting control, except 

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

COLORADO RIVER BASIN 5j5 

SAN SABA RIVER NEAR SAN SABA, TEX.

LOCATION. 200 feet above Beveridge highway bridge, 1 mile below mouth of 

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

mouth of Richland Creek, and 4 miles above mouth of Simpson Creek.

DRAINAGE AREA. 3,040 square miles, revised (measured on standard topographic 

maps; post-route map; and topographic map of Texas, compiled in 1899 by 

Robert T. Hill, of the United States Geological Survey; scale, 1 inch ==25 

miles). .

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

11," 1915, to September 30, 1922. Miscellaneous discharge, measurements 

previous to 1904. '.

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

December 30, 1904, to December 31, 1906, gage heights were obtained by 

measuring with a tape from a reference point on the bridge to the water 

surface. Relation between datum used 1904-1906 and that of present gage 

is not known.

DISCHARGE MEASUREMENTS. Made by wading or from downstream side of 

bridge.

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

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

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

and gravel, wooded, sloping, medium in height, 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; control is free from vegetation and 

shifts.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, about 37.0 

feet on April 26 or 27, determined from flood marks on gage (discharge not 

determined); minimum stage, 1.30 feet at 6.15 p. m. March 22 and 5.40 p. m. 

March 24 (discharge, 25 second-feet).

1904-1906; 1915-1922: Maximum stage recorded, that of April 26 or 27, 

1922; no flow August 9 and 10,1918.

ICE. None reported.

DIVERSIONS. Considerable water is diverted from stream and tributaries above 

station. There are also diversions below the station but none in the vicinity 

of 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 by diversions below station.

REGULATION. None.

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

between 5 and 6,500 second-feet. Gage read to hundredths twice daily. 

Daily discharge determined by indirect method for shifting control. See 

also footnote to daily-discharge table. Records fair.

miles below station.

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

and below for 400 feet, with a series of pools and rapids. Left bank high, 

clean, and not subject to overflow; right bank low, 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 feet 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, 8.7 feet at 

6.45 p. m. April 3 (discharge not determined). (Observer reports highest 

stage occurred during night of May 2, stage unknown); minimum stage, 

0.96 foot from 4.20 p. m. September 8 to 6 p. m. September 9 and 5.35 

p. m. September 15 to 5.45 p. m. September 18 (discharge, 0.40 second-foot). 

1915-1922: Maximum stage recorded 18.00 feet during-night of September 

15, 1915 (discharge not determined); no flow during several periods.

ICE. None reported.

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

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

above the station. During low stages such diversions materially reduce 

flow at the station.

REGULATION. No indication that flow at station is regulated.

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

below 120 second-feet. 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 for low 

and medium stages. <

COLORADO RIVER BASIN 59 

IIANO BITER NEAR JUNCTION, TBX.

LOCATION. 100 feet north of Kerrville-Junction road, a quarter of a mile northeast of Oliver's ranch house, 3 miles below confluence of North Llano and 

South Llano rivers, 3J^ miles east of Junction, Kimble County, and 4 miles 

above creek entering river from south.

DRAINAGE AREA. 1,700 square miles (measured on standard topographic maps; 

post-route map; and topographic map of Texas, compiled in 1899 by Robert 

T. Hill, of the United States Geological Survey; scale, 1 inch=25 miles).

RECORDS AVAILABLE. September 13, 1915, to September 30, 1922.

GAGE. Vertical staff, reading from 0 to 7.5 feet, attached to tree on right bank, 

and inclined staff graduated from 7.0 to 14.7 feet, and a vertical staff 14.6 

to 20.3 feet; the two latter sections are 100 feet upstream from low-water 

vertical staff; read by Sadie Oliver.

DISCHARGE MEASUREMENTS. Made by wading at Mason road crossing, a quarter 

of a mile above gage or from cable 400 feet above gage.

CHANNEL AND CONTROL. Bed composed of solid rock, clean, and permanent. 

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

of medium height, slightly wooded, and subject to overflow during high 

water; right bank clean, high, and not subject to overflow. One channel 

at all. stages, except during extreme floods, when a small part of the flow 

may follow a slough that leaves the river a short distance above the gage, 

passes to the south of Oliver's ranch house, and enters the main stream 

below the gage. Such conditions do not occur, however, at intervals more 

frequent than 10 to 15 years, and will not greatly affect records. Rock 

ledge 75 feet below gage, forming a fall of approximately 3 feet, serves as 

permanent control for low and medium stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during the year, 10.97 

feet at 9.30 a. m. April 3 (discharge not determined); minimum stage, 1.50 

feet at 2 p. m. October 30 and 31 (discharge, 52 second-feet).

1915-1922: Maximum stage recorded, 26.3 feet at 3 a. m. September 16, 

1915 (discharge not determined); minimum stage, 1.32 feet during August 

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

ICE. None reported.

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 1,300 acres below station. Diversions materially 

reduce flow at station during low stages.

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

at Junction.

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

from 24 to 250 second-feet. Any discharge above 250 second-feet is from 

extension of rating curve and subject to error. Gage read to hundredths 

once daily, but observer's work doubtful. Daily discharge ascertained by 

applying mean daily gage height to rating table, except as noted in footnote 

to daily-discharge table. Records good for low and medium stages.

compiled in 1899 by Robert T. Hill, of the United States Geological Survey ;

scale, 1 inch=25 miles).

RECORDS AVAILABLE. December 16, 1917, to September 30, 1922. 

GAGE. Vertical staff in two sections on left bank; read by Robert W. Faust. 

DISCHARGE MEASUREMENTS. Low-water measurements made by wading. No

high-water section available. 

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

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

low, wooded, and subject to overflow.

EXTREMES OP DISCHARGE. Maximum s,iage recorded during year, 6.9 feet ajt' 

,, 8 a. m. April 26 (discharge not determine^); minimum stage during period

of estimated discharge (discharge, probably about 25 second-feet).

62 SURFACE WATER SUPPLY, 1922, PART VIII

REGULATION. At Kerrville and Center Pointj dams are constructed and water 

used for mill purposes, but the effect of the regulation is slight except during 

low stages.

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

defined below 40 second-feet, well defined from 40 to 80 second-feet, and 

poorly defined from 80 to 270 second-feet. Gage read to hundredths once 

daily, but not regularly, and observer's work doubtful. One reading a day 

may not be true index to discharge at low periods, owing to storage and 

intermittent pumping above gage; and at high stages, owing to rapid fluctuations. Daily discharge ascertained by applying mean daily gage height to 

rating table, except as otherwise noted in footnote to daily-discharge table. 

Records poor.

T. Hill, of the United States Geological Survey; scale, 1 inch=25 miles). 

RECORDS AVAILABLE. March 13, 1898, to December 30, 1899; January 27, 1915, 

to September 30, 1922.
BASIl?

GAGE. SteveM .Tfeteivj&age recorder, attached to downstream side o£naiddle 

pier of highway bridge; inspected by engineers from Austin office. A vertical staff gage in three sections attached to- trees on left bank 200 feet below 

highway bridge, and one section on eatt side of left pier of highway bridge, 

was read from January 27, 1915, to September 28, 1917, when recorder was 

installed.. Gage used from March 13, 1898, to December 30, 1899, was an 

inclined staff, gage near the present highway bridge; relation between datum 

of inclined gage and of the vertical staff gage not known. During normal 

flow, levels show 0.08 foot fall between intake of recorder and vertical staff 

gage location. Vertical staff gage in well of, recorder set to read same as vertical staff downstream.

DISCHARGE MEASUREMENTS. Made from upstream side of bridge.

CHANNEL AND CONTROL. Bed composed of solid rock with pockets of coarse 

giavel. Banks, gravel, clay, and rock, slightly wooded, high, and not subject 

to overflow. Rock and gravel shoal just below gage serves as control; changes 

slightly.

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

7.95 feet at 11.50 a. m. April 27 (discharge, 6,190 second-feet); no flow for two 

hours on each of the following days, owing to regulation at dam under con? 

structionSOOfeetabove gage, August 2,4,10,18, September3,8,14,21, and28. 

1898-1899; 1915-1922: Maximum stage recorded, 28.6 feet at 3 a. m. 

September 10, 1921 (discharge, 56,600 second-feet, determined from extension of rating curve and subject to error); minimum stage, that of August 2, 

4, 10, 18, September 3, 8, 14, 21, and 28, 1922.

ICE. None.

DIVERSIONS. Some water diverted for irrigation above station in Kerr and 

Comal counties, and for water-power, water-works, and other municipal 

uses in Kerr, Kendall, and Comal counties; amount not known.

REGULATION. Flow at this point entirely regulated at times by operation of 

power plants on Comal River and by plant 300 feet above. See footnote to 

daily-discharge table.

ACCURACY. Stage-discharge relation not permanent, owing.to construction operations on dam near gage. Rating curve weJU. defined for all stages. Opera*- 

tion of water-stage recorder satisfactory, except for short breaks in record. 

Mean daily gage heights obtained from recorder graph by inspection or by use 

of planimeter. Daily discharge ascertained by indirect method for shifting

, , ^ ,;; GUADAIUPE RIVEE HEAR GONZALES, TBX.

LOCATION. =Just below daih of Gonzales Water Power Co., 1 mile above Guadaliipe Hgitway bridge; in Gonzales, Gonzales County, and 1% mlles'below 

mouth of San Marcos River. / *..,- -

DRAINAGE AREA. 3,620 square miles (measured on standard topographic maps; 

post-route map; and topographic map of Texas, compiled in 1899 by Robert 

T. Hill, of the United States Geological Survey; scale, 1 inch =*25 miles).

RECORDS AVAILABLE. July 1, 1915, to September 30, 1922. The United States 

Weather Bureau has obtained records from this gage at the power house of 

Gonzales Water Power Co. since September 1, 1904.

GAGE. United States Weather Bureau gage at tailrace of Gonzales Water 

Power Co.'s plant. From July 1, 1915, to September 30, 1920, vertical staff 

in three sections on right batfk, just below bridge a mile downstream, was' 

used. Curve showing relation between gage readings at the two sites has 

been developed. . DISCHARGE MEASUREMENTS. Made from cable one-fourth of a mile below bridge 

and \^i miles below gage or by wading near bridge. Measurements made 

from highway bridge above stage of 22 feet when banks are overflowed at 

cable section.

CHANNEL AND CONTROL. Bed composed of gravel and sand; channel above and 

below station straight for 500 feet. Dam and power house just above gage. 

Banks composed of gravel and clay; right bank medium height, wooded, 

and subject to overflow; left bank high and not subject to overflow except 

. at extremely high stages. At bridge, left bank protected by levee which 

does not overflow except during unusually high stages; right bank at bridge 

is overflowed at stage of about 27 feet. Control is rock and gravel shoal 

about 200 feet downstream from gage; shifts. At a stage of about 21.5 feet 

(discharge, 11,400 second-feet) water begins to enter an old channel, locally 

known as Cross Timbers, on right bank 1 mile above gage and returns to 

main channel below gage. Consequently, all records of. discharge greater 

than 11,400 second-feet do riot represent the total flow of the stream, but 

only that in the main 'channel.

EXTREMES OF DISCHARGE. Maximum stage during year, 33.3 feet, April § 

(discharge, 40,300 second-feet, determined from extension of rating curve 

and subject to error); minimum stage, 1.0 foot August 27, September 17, 

and 24 (discharge, 430 second-feet).

'1915-1922: Maximum stage from Weather Bureau records at Gonzales 

dam, 34,1 feet at 7,p..m, October 18, 1919 (discharge, 43,600 second-feet, 

determined from extension' of rating curve and subject to error); minimumstage, 0.02 foot at 5.30 p. m. October 20, 1918 (discharge, 155 second-feet).

ICE. None reported.

DIVERSIONS. Some water diverted above the station for irrigation and municipal 

uses, but the amount is small in comparison with the total run-off. As 

rainfall is nearly sufficient ior general farming, irrigation is intermittent and1 

it i& extremely difficult to estimate the amount of water used.

REGULATION. Flow at this point regulated somewhat by operation of water-? 

power plants. Power house of Gonzales Water Power Co. is just above gage.
68 SURFACE WATER SUPPLY, 1922, PART vni

ACCURACY. Stage-discharge relation fairly permanent. However, measurements are made 1 mile below, gage and, owing to operation of turbines at 

Gonzales dam, at which gage is located, there.may be discrepancies between 

the stage at the dam and discharge relation at the measuriftg .section. 

Rating, curve for main channel well defined from 400 to 10,000 second-feet, 

.and poorly defined from 10,000 to 28,000 second-feet. Above 11,400 feet, 

some water enters old channel on right bank about 1 mile above gag^e, locally 

known as Cross Timbers, and returns to main channel below gage. United 

States Weather Bureau gage readings made to nearest tenth once daily. One 

reading daily may not be true index to discharge, owing to operation of 

turbines just above gage, and to rapid fluctuations. Daily discharge ascertained by applying daily gage heights to rating table. Records poor.

COOPERATION. Gage heights furnished by United States Weather Bureau.

GUADALUPE RIVER BELOW CUERO, TEX.

. Three-fourths mile upstream from Heards Bridge on Arneckville 

road, 1 mile south of Dietze farmhouse, 2 miles below Clinton Bridge, 2% 

miles southeast of Cuero, Dewitt County, 4 miles below Schleicher Bridge, 

. and 8 miles below dam used for power development.

DRAINAGE ABBA. 5,020 square miles (measured on standard topographic maps; 

post-route map; and topographic map of Texas, compiled in 1899 by Robert 

''T. Hill, of the United States Geological Survey; scale, 1 inch =25 miles). 

RECORDS AVAILABLE. August 6, 1916, to September 30, 1922. (Fragmentary 

from May 29, 1919, to August 10, 1920). From December 26, 1902, to 

December 31, 1906^ and August 19, 1915, to August 6, 1916, a station was 

maintained at Schleicher Bridge, 4 miles above this point. Discharge at 

two sites practically the same.

GAGE. Stevens water-stage recorder on left bank; inspected by E. B. Dietze. 

DISCHARGE MEASUREMENTS. Made from cable 40 feet upstream from gage

or by wading near gage.

CHANNEL AND CONTROL. Channel straight above and below station for 1,000

feet. Bed composed of gravel and small pock; clean and shifts slightly.

Left bank composed of sand and dirt, covered with brush and open timber,

.. and is 20 feet high, but at stages above a gag£ height of 20 feet is overflowed,,

, the water submerging an area for one-four4fa mile back from river; right

 bank composed of sand and dirt, covered with brush and trees on sloping 

,. side and cultivated land on top; high, and not subject to overflow. Rock 

and gravel rapid 250 feet below gage serves as a control during low and 

medium stages; shifts slightly. 

EXTREMES OF DISCHARGE. Maximum stage during year from auxiliary gage,' 

; 26.5 feet at 7,40 p. m; April 7 (discharge, 36,000 second-feet); minimum"; 

stage, owing to regulation, probably about 0.80 foot for short time during! 

moiling of November 8 (discharge, 195 second-feet).

1916-1922: Maximum stage occurred about October 20, 1919, when 

recorder was not in operation, and reached a height of about 32.15 feet asf 

determined from flood marks on gage house (discharge, not determined) £f 

minimuin stage from water-stage recorder, approximately 0.58 foot from9 to 1O a. m. November 1, 1917 (discharge, 80 second-feet, determined from

 . .extension of rating curve and possibly slightly in error).

101120 25t WSP 548 -6
70 SURFACE WATER SUPPLY, 1922, PART VIII

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 permanent during the year. Curve well 

defined between 200 and 15,000 second-feet, and fairly well defined t» 

36,000 second-feet. Operation of water-stage recorder not satisfactory. 

Daily discharge ascertained by applying to rating table mean daily gage 

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

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

SAN MARCOS RIVER AT OTTINE, TEX.

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

County, 4 miles below mouth of Plum Creek, and 10 miles above confluence 

of San Marcos and Guadalupe rivers.

DRAINAGE AREA. Indeterminate.

EECORDS AVAILABLE. June 22, 1915, to September 30, 1922.

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

Kaine. Gage used from June 22 to October 12,1915, was a vertical staff under 

the highway bridge, but gage heights have been reduced to datum of succeeding gage by means of a curve showing relation between readings of the 

two gages. Gage used from October 13, 1915, to March 15, 1920, was 

vertical staff in four sections attached to trees on left bank about 400 feet 

above bridge.

DISCHABQE MEASUREMENTS. Made from downstream side of highway bridge 

or by wading at shoal 200 feet above bridge.

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

Banks high and wooded; right bank is overflowed at 2§«7 feet gage heighjt 

and left bank at 34.0 feet gage height. Channel straight above and below 

station for 150 feet. Low-stage control formed by shoal 150 feet below 

gage. During high stages in Guadalupe River backwater affects stagedischarge relation. ' 

EXTREMES OF DISCHARGE. Maximum stage recorded during year> 37.0 feet at 

6 p. m. .April 4 (discharge, not determined); minimum stage, 1.48 feet at 

10.30 a..na, July 17 (discharge, 10 second-feet, owing to.regulation at damf 

. short distance above gage). Minimum mean daily discharge February 11> 

March 13, 20, 21 (discharge, 132 second-feet).

1915-J922: Maximum stage recorded, 37.5 feet at 7.30 a. m. May 16, 

; 1920 (discharge not determined); minimum discharge, that of July 17^ 

1922. Stages not comparable, owing to shifting control and" changes in" 

datum of gages.

IcE.-^J^one reported.

^DIVERSIONS. -Small amounts of water are diverted above the station for ifrigar 

tibn; an4 municipal uses, but only a small part of the total run-off is used. 

Little, if an-"-, water is diverted below the station.
72 SURFACE WATER SUPPLY, 1922, PART VIII

REGULATION. Flow regulated by the operation of a small cotton gin a1 shotf 

distance above the station. The operation of several small water-power 

plants in the upper drainage basin near San Marcos and Martindale does 

not materially affect the flow at this station.

ACCURACY. Stage-discharge relation not permanent. Two rating curves used. 

One from October 1 to April 4 well defined from 150 to 15,000 second-feet 

and one from April 5 to September 30 well defined between 0 and 15,000 

second-feet. Gage read to hundredths twice daily, but mean of two readings daily may not be true mean, owing to power regulation above gage. 

Daily discharge ascertained by applying mean daily gage height to rating 

table, except October 1 to March 28 and September 5 to 30 when indirect 

method of shifting control was used. Records good.

SAN ANTONIO RIVER AT SAN ANTONIO, TEX.

LOCATION. At South Alamo Street Bridge in San Antonio, Bexar County, 4 

miles below San Antonio Springs, source of normal flow of river, and 1|^ 

miles above mouth of San Pedro Creek,

DRAINAGE AREA. Indeterminate.

RECORDS AVAILABLE. January 26, 1915, to September 30, 1922. Miscellaneous 

. discharge measurements were made from 1895 to 1906.

GAGE. Gurley graph water-stage recorder on right bank at downstream side of 

bridge. Gage used from January 26, 1915, to February 28, 1916, was vertical staff attached to downstream side of middle pier of Commerce Street 

Bridge. Gage used from February 29, 1916, to April 8, 1920, was vertical 

staff, attached to upstream side of second bend of Presa Street Bridge. -Relation of readings of different gages not determined. Discharge at various 

gages is probably not materially different.

DISCHARGE MEASUREMENTS. Made from upstream side of bridge or by wading.

CHANNEL AND CONTROL. Channel straight for.'. 100 feet below gage and curved 

above. Bed composed of sand, gravel, and silt. Control formed by gravel, 

bar; shifts.

EXTREME'S OF DISCHARGE. Maximum and minimum stages not 'determined, 

owing to work on bridge which interfered with operation of recorder.

1914-1922: Maximum stage recorded, 20.14 feet about 3 a, m. September 

10, 1921, determined from flood mark on gage (discharge, 15,300 secondfeet, determined by slope method, using value of 0.035 and 0.050 for "n" 

in Kutter's formula). Minimum stage, 0.58 foot on several days during 

November and December, 1918 (discharge, 7.0 second-feet),.

JCE. None reported. . ' ' "

DIVERSIONS. Quantity of Water diverted above gage not known but it is believed to be immaterial. Considerable land is irrigated from diversions 

below gage.

REGULATION. The operation of water wheels,,at the Guenther flour mill ju^t 

above the gage causes ifrequent bitt unimportant fluctuations in stage. - 
74 SURFACE WATER SUPPLY, 1922, PART VIII

ACCURACY. Stage-discharge relation not permanent. Two-rating curved used 

during year. One used from October 1 to January 28, and one from June 

10 to September 30; both fairly well defined for all stages during the year. 

Operation of, water-stage recorder not satisfactory as noted in footnote 

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

table mean daily gage height obtained from recorder charts by inspection or 

by use of planimeter, except that shifting-control method was used October 

, 6 to January 28 and as noted in footnote to daily-discharge table. Record^ fair.

. The normal flow of San Antonio River comes from springs within tjqte city 

limits, but two tributaries from the north furnish considerable run-off at'tiHX'0 

of heavy precipitation. Changes in stage during low flow are believed to be.d«e to 

pumping from deep wells for the city water supply and the use of artesian watfej 

'for irrigation in areas adjacent to the river, for it is thought that the wells draw 

from the underground reservoir that feeds the river by springs.

> SAN ANTONIO RIVER Af CALAVEBAS, TEX.

LOCATION. One-fourth mile s*outh of San Antonio & Aransas Pass Railway 

station in Calaveras, Wilson County, 1 mile below mouth of Calaveras Creek, 

and 10 miles below mouth of Medina River.

DRAINAGE AREA. 1,870 square miles (measured on topographic map of Texas, 

compiled in 1899 by Robert T. Hill, of the United States Geological Survey; 

scale, 1 inch =25 miles). " RECORDS AVAILABLE. March 12, 1918, to September 30, 1922i

GAGE. Vertical staff in five aections on left bank near old briek plant; read by 

I. M. Smith. ;

DISCHARGE MEASUREMENTS. :Made from highway bridge half a mile upstream 

from gage or by wading below gage.

CHANNEL AND CONTROL. Bed composed of sand and clay and free from vegetation; shifts. Channel straight above and below station for 150 feet. Left 

bank high, wooded,-and not subject to overflow; right bank steep, 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, 27.4 feet 

during night of May 3 (discharge, 7, 440 second-feet); minimum stage, 1.90 

feet September 3, 8, and 9 (discharge, 83 second-feet).

1918-1922: Maximum stage recorded, 42.0 feet at 4 a. m. September 11, 

1921 (discharge, not determined); minimum stage, 0,14 foot, at 8.30 a. m. 

September 14, 1918 (discharge, 15 second-feet)..

ICE. None reported.

DIVERSIONS. The Medina dam and reservoir, with a storage capacity of 254,060 

acfe-feet, is located on Medina River about 50 miles above its confluence 

with the San Antonio. The diversion works, having a capacity of 850 

second-feet, are 4 miles below the Medina dam. Probably about 5,000 acres 

were under irrigation in this project in 1922.

REGULATION. The ordinary flow may be slightly affected by storage and diver- 

. sions on Medina River.
76 SURFACE WATER SUPPLY, 1922, PART VIII

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

defined^ between 30 and 1,500 second-feet, and extended above this by use 

of A^/ d method with measurement No. 10 at a discharge of 11,000 secondfeet as a basis; subject to error. Gage read to hundredths twice daily and 

oftener during floods. Mean of two readings a day may not be true index 

to discharge, owing to rapidly changing stages. Daily discharge ascertained 

by indirect method for shifting control and partly estimated January 15-19. 

Records fair for low and medium stages and poor for high stages.

attached to wall of building No. 713 Commerce Street, on upstream side of 

bridge on left bank was used.

DISCHARGE MEASUREMENTS. Made by wading near gage 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 OP DISCHARGE. Maximum stage during year from water-stage recorder, .5.25 feet at 9.10 p. m. May 2 (discharge, 788 second-feet, determined from an extension by use of Kutter's formula and subject to error); 

minimum stage, 0.44 foot at 8 p. m. April 12 (discharge, 4.8 second-feet).

1916-1922: Maximum stage recorded, 8,6 ifeet at 11.30 p. m. September 9, 1921, when backwater from Alazap Creek existed (discharge, not 

determined); minimum stage, 1.30 feet, December 10-11, 1918 (discharge, 

0.7 second-foot).

ICE. None reportedDIVERSIONS. '-None. . ',

REGULATION. Partly regulated by dam at swimming pool at San Pedro Springs.
78 STJEFACE WATEB SUPPLY, 1922,'^ART VIII

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

from 7 to 11 second-feet; poorly defined from 11 to 200 second-feet, and extended above by means of Kutter's formula with a value of n of 0.014 at 

gage height 6.0. feet. Daily discharge ascertained by applying to rating 

table mean daily gage height obtained from recorder chart by inspection or 

by use of planimeter. Records good.

Entire flow of San Pedro Creek, except during times of heavy precipitation, 

is. furnished by Sari Pedro Springs, and the flow at this station is believed to be 

 that which reaches San Antonio River. Martinez and Salsamora creeks carry 

tto water except during heavy local rains and have been known to be dry for 

several years at a time.

NUECES RIVER BASIN 

NUECES BIVEB NEAR CINONIA, TEX.

LOCATION! Just below suspension bridge near Oswald ranch, 2 miles east of 

Cinonia, Zavalla County, 8 miles northeast of Crystal City, and 20 miles, 

above dam on Winter Garden ranch.

DRAINAGE AREA. 2,060 square miles (measured on- standard topographic; 

maps; post-route map; and topographic map of Texas, compiled in l&9t^ 

by Robert T. Hill, of the United States Geological Survey; scale, 1 inch=25 

miles).

RECORDS AVAILABLE. July 5, 1915, to September 30, 1922.

GAGE. Vertical staff in six sections installed May 6, 1918, on right bank, 20O 

feet below, highway bridge; read by C. C. Oswald. From July 5, 1915, to 

September 23, 1917, gage used was vertical staff in seven sections on right 

and left banks. September 24, 1917, to May 5, 1918, Dexter water-stage 

recorder near concrete control. All gages set at same datum and at approximately the same location.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by: 

wading on crest of concrete control.

CHANNEL AND CONTROL. Bed composed of elay and gravel; free from vegetation; subject to shift prior to September 23, 1917. Banks high and wooded 

and ndt subject to overflow, except during extremely high water. Channel 

straight above and below station. An artificial concrete control was completed at the site of the gage on September 23, 1917; point of zero flow, 

0.85 foot.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 23.94 feefe 

at 7 p. m. June 13 (discharge, 3,530 second-feet, determined from extension 

of rating curve and subject to error); minimum stage, 1.16 feet from 7 a. ni» 

October 1 to 7 a. m. October 13 (discharge, 2.6 second-feet).

1915-1922: Maximum stage recorded, 49.1 feet September 23, 1919, 

determined by leveling from flood marks (discharge not determined). According to local residents, the greatest flood on record occurred in 1913y 

when the river reached a stage of about.,53 feet ,by present gage datum. 

No flow during several periods of record.

ICE. None reported. . ,

DIVERSIONS. Considerable water diverted above*station for irrigation; amount 

not known.

REGULATION. None.
19TJECES BIVBE BASIN

ACCURACY. Stage-discharge relation permanent. Cufcve well defined below 

700 second-feet, and extended above by means of area-velocity curves. 

Gage read to hundredths twice daily. Daily discharge determined by 

applying mean daily gage heights to rating table. Records for low and 

medium. stage,s good, and for high stages fair.

Backwater from a dam 40 feet high, about 20 miles below station, extends 

within 2 miles of-station when reservoir is lull. A large part of-the flow of the 

river is known to seep into the bed just below Uvalde and return .to./the surface 

just above the station. The condition of the underground wateiMfiay have a» 

effect on this return water and thus help to equalize the flow. : , 

The following discharge measurement was made by Dudley, and West: 

October 5, 1921: Gage height, 1.18 feet; discharge, 2.67 second-feet. .

Daily discharge, in second-feet, of Nueces River near Cinonia, Tex., for the year

NUECES EIVER AT CAIALIEN, TEX.

LocATiOEf. At old pump house for city of Corpus Christi, half a mile northwest 

of Calallen, Nueces County, 18 miles west of Corpus Christi, 8 miles above 

Nueqes Bay, and half a mile above edge of tidewater and breakwater dam.

DRAINAGE AB^A. r!6,700 square miles (measured op post-route map and topographic map of Texas, compiled in 1899 by Robert T. Hill, of the United 

States Geological Survey; scale, 1 inch ==25 miles).

RECORDS AVAILABLE. August 12, 1915, to September 30, 1922.

GAGE. "-Vertical staff attached to pipe-line support of old pump house; read by

: John' W. Cunningh^m.

DISCHARGE MijAStrREMEUTs.- ;Made by wading at the; backwater or from cable 

125 feet below gage.

ELI AND CONTROL. Be<J composed of clay and gravel. Channel straight 

above and below station. Left bank wooded, low, and bordered by levee 

constructed to prevent overflow; right bank wooded, medium in height, 

and not subject to overflow. The breakwater dam, which is a loose rock fill 

half & mile below, serves as control. It leaks badly arid is subject to change 

during floods. Flood damage is repaired by dumping loose rock on the crest.
SUKPACE WATER SUPPLY, 1922, PART VIII

EXTREMES or'STAGE. Maximum stage recorded, 9.60 feet at 8 a. m. May 9 ti> 

8 a. m. May 10; minimum stage, 1.20 feet, 4 p. m. November 1 to 4 p. m. 

November 2, and 8 a. m. November 8 to 4 p. m. November 12, and 4 p. m. 

September 12 to 4 p. m. September 16.

1915-1922: During September, 1919, the river reached a stage of about 

12 feetj as determined from flood marks on the gage. This was not only the 

highest stage reached during,the 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 being: 

overflowed for a width of several miles. No flow August 23-28, 1918.

ICE. None reported.

DrvEBSioNs. Considerable water taken from river for irrigation immediately 

above station, and river water is also used for irrigation throughout the; 

drainage above. The city of Corpus Christi pumps water just below the 

gage for municipal supply. They reported a consumption of 922 acre-feetduring 1918.

REGULATION. None of consequence.

ACCURACY. Stage-discharge relation not permanent because of leakage through 

and repair to the breakwater dam. Rating curve is poorly defined. Gage 

read to hundredths twice daily. Daily discharge not computed because'of 

changing control and insufficient discharge measurements. Records poorNo discharge measurements were made at this station during the years 1920r

1921, and 1922.

covered by frequent discharge measurements. Two rating curves used 

One used from October 1 to June 30 well defined from 80 to 500 second-feet, 

and one used from July 1 to September 30 well defined from 30 to 600 secondfeet; both extended parallel to previous curve to cover range of stage for the 

year. Mean daily gage height determined from recorder graph. Daily 

discharge determined by applying mean daily gage height to rating table 

except for October 21 to February 26, May 11 to June 30, and July 15 to 

August 31, when shifting-control method was used. Records good.

RECORDS AVAILABLE. May 28, 1903, to March 31, 1908; May 13, 1914, to 

September 30, 1922.

GAGE. Stevens eight-day water-stage recorder, attached to downstream end of 

middle bridge pier, installed June 1, 1920j inspected by J. R. Yates. Gage 

used from May 28, 1903, to October, 1904, was inclined staff gage at the 

present site. From October, 1904, to March 31, 1908, vertical staff gage at 

the same site used, and from May 18, 1914, to June 1, 1920, gage was vertical 

staff, attached to upstream side of middle pier of bridge.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTKOL. Bed composed of gravel and rock; but considerable 

changes have taken place, due to sand deposits. Banks of medium height; 

not .subject to overflow. Location of control not known.

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

1.60 feet at 6.30 p. m. October 14 (discharge, 590 second-feet); minimum 

stage, 0.57 foot at 7 p. m. August 22 (discharge, 73 second-feet).

1903-1908; 1914-1922: Maximum stage recorded, about 21.0 feet August 

7, 1916 (discharge, 85,700 second-feet 5); minimum discharge, 30 second-feet 

September 30, 1918.

ICE. None reported.

DIVERSIONS. Large quantities of water are stored a few miles above station at 

Lakes McMillan and Avalon by the United States Bureau of Reclamation 

for irrigating land near Carlsbad. Water is also diverted for irrigation in 

valleys adjacent to river above Lake McMillan. Capacity of storage 

reservoirs in connection with the Carlsbad project, 58,500 acre-feet. Considerable water seeps into the river between the .storage reservoirs and the 

gaging station, the quantity depending on the amount being used for irriga-, 

tion between the two points.

Discharge at Avalon dam; reported by engineers of the United States Bureau of Reclamation.
RIO GBANDE BASIN 95

REGULATION. Flow at this point completely controlled' by storage reservoirs 

of the Carlsbad project, except during extreme floods.

PECOS RIVER NEAR MALAGA, ft. MEX.

LOCATION. In sec. 18 or 19, T. 24 S., R. 29 E., 3J^ miles southeast of Malaga, 

Eddy County, and 4J4, miles below mouth of Black River.

DRAINAGE ABBA. Not measured.

RECORDS AVAILABLE. May 1, 1920, to September 30, 1922.

GAGE. Stevens seven-day water-stage recorder installed on right bank with 

staff gage attached to still well; inspected by W. F. Gerlach.

DISCHARGE MEASUREMENTS. Made from cable or by wading near gage.

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 by sand, 500 feet below gage; shifts.

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

recorder, 7.0 feet at 2 a. m. April 25 (discharge, 1,790 second-feet); minimum 

stage, 3.40 feet at 6 p. m. June 25 (discharge, 53 second-feet, determined 

from extension of rating curve and subject to error).

1920-1922: Maximum stage from water-stage recorder, 12.85 feet at,l 

a. m. June 8 (discharge, 22,000 second-feet, determined from extension of 

. curve and subject to error); minimum stage that of June 25, 1922.

In September, 1919, the river reached a stage of 26.4 feet (discharge not 

determined.)

ICE. None reported.

DiVERSioNs.r The Carlsbad project of the United States Bureau of Reclamation, with reservoirs of 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 the stream by seepage from lands in 

the vicinity of Carlsbad. In addition to the water used by the Carlsbad 

project, some diversions are made for irrigation in the basin above the 

storage reservoirs of the Carlsbad project.

REGULATION. The operation of the 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.
BIO GBANDE BASIN 97

ACCTTBACT. Stage-discharge relation not permanent. Two rating curves used. 

One used from October 1 to December 31 is well defined from 140 to 300 

second-feet, and one used from January 1 to September 30 is well defined 

from 100 tp 400 second-feet; both curves extended parallel! to previous 

 curves to cover range of stage. * Operation of water-stage recorder satisfactory. Daily discharge determined by applying to rating table mean 

daily gage height obtained from recorder graph by inspection, by planimeter, or by averaging gage heights for fractional parts of a day, except &s 

noted in footnote to daily-discharge table. Records good.

COOPEBATION. Daily-discharge record furnished by United States Bureau of 

Reclamation.

PECOS BX7EB NEAR A3GELES, TEX.

LOCATION. In T. 26 S., R. 29 E., just below Pecos Valley Railroad bridge crossing Delaware Creek at its mouth, 2 miles north of New Mexico-Texas State 

line, 2^i miles southeast of Red Bluff, Eddy County, N. Mex., and 8H miles 

northwest of Angeles, Reeves County, Tex.

DRAINAGE ABEA. 'Not measured.

RECORDS AVAILABLE. May 27, 1914, to September 3(f, 1922.

GAGE. Stevens continuous, water-stage recorder, at first outcropping of rock oa 

right bank about 600 feet below railroad bridge and mouth of Delaware 

Creek; inspected by United States 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 a series of rapids 200 feet 

below gage; shifts.

EXTREMES OP DISCHARGE. Maximum stage during year from water-stage recorder, 5.62 feet at 11.30 a. m. April 25 (discharge, 9,200 second-feet, determined from extension of rating curve and subject to slight error); minimum 

stage, 0.01 foot 10 a. m. to 4 p. m. June 26 (discharge, 97 second-feet, determined from extension of rating curve and subject to slight error).

1914-1922: Maximum stage recorded, 21.5 feet at 10 a. m. August 8, 1916, 

measured by leveling from flood marks (discharge not determined); minimum discharge, 80 second-feet February 27, 1919.

ICE. Stage-discharge relation not seriously affected by ice.; open channel rating 

assumed applicable.

DIVERSIONS. The Carlsbad project of the United States Bureau of Reclamation, 

the reservoirs of which have a total 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 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 Carlsbad project.

REGULATION. The 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., docs not materially regulate flow at gage. 

The flow is, however, regulated to a large extent by water 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.
RIO GBANBE BASIN 99

ACCURACY. Stage-discharge relation not permanent. Bating curve well denned 

for all stages. Operation of water-stage recorder not satisfactory. Mean 

daily gage height obtained from recorder chart by inspection or by use of 

planimeter. Daily discharge ascertained by indirect method for shifting 

control, or as noted in footnote to daily-discharge table. Records fair.

Irrigation District No. 1), 4 miles below former location, and 10 miles northwest of Barstow, Ward County, Tex.

DBAINAGB AKEA. Not measured.

RECORDS AVAILABLE. February 1, 1916, to May '11, 1921, and March 22 toSeptember 30, 1922.

GAGE. Gurley eight-day water-stage recorder on left bank; attended by R. G. 

Hamilton or United States Geological Survey engineers. From February 

1, 1916, to May 11, 1921, gage was Stevens continuous water-stage recorder, 

located 4 miles upstream. Relation between gages not known.

DISCHARGE MEASTTBEMENTS. Measurements made by wading, from cable near 

gage, or from Texas Pacific Railroad 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, 

clean, steep. Left bank is high and not subject to overflow. Right bank 

high and subject to overflow at extremely high stages. Low-water control 

is rock ledge, 150 feet below gage; permanent. Point of zero flow about 

1.3 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year from waterstage recorder, 7.90 feet at 9 a. m. April 26 (discharge, 1,900 second-feet, 

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

stage, 1.40 feet August 27 to September 4 (discharge, 0.30 second-feet, due 

to regulation just above present location).

1915-1922: Maximum stage from water-stage recorder, 12.1 feet (by 

datum of former location) at 6 a. m. August 10, 1916 (discharge not determined) ; minimum stage, that of August 27 to September 4, 1922.

DIVERSION. In addition to water diverted in New Mexico by the Carlsbad 

project, the three principal diversions in Texas are the Farmers Independent, 

Cedar vale (formerly Biggs), and Barstow canals. Small amount 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.

ACCUBACY. Stage-discharge relation permanent for the period. Rating curve 

well defined from 0 to 200 second-feet and1 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 use of planimeter, except as noted in footnote to 

daily-discharge table. Records fair.

104 SUBFAGE WATER SUPPLY, 1923, PAET VIII 

PECOS RIVER NEAR GRANDFAIJS, TEX.

LOCATION. At site of old highway bridge where Grandfalls-Fort Stockton road 

formerly crossed Pecos River, 1J^ miles upstream from present GrandfallsFort Stockton road crossing at Iron Bridge, 2 miles below diversion dam for 

the low-line (silt-line) canal of Imperial Irrigation Co., 3 miles south of 

Grandfalls, Ward County, 4J^ miles, above diversion dam of Zimmerman 

project, and 21 miles south of Monahans.

DRAINAGE AKEA. Not measured.

RECORDS AVAILABLE. November 6, 1915, to September 30, 1922. Records 

were taken at Iron Bridge, IJ^s miles downstream, from November 6,1915, to 

August 3, 1917. Discharge at both points believed to be the same.

GAGE. Stevens water-stage recorder installed August 9, 1917, on downstream 

side of old bridge pier near left waters edge; inspected by A. J. Adcock, and 

an engineer from the United States Geological Survey office. Prior to 

August 3, 1917, a Stevens water-stage recorder at Iron Bridge. Backwater 

from Zimmerman dam compelled the relocation of the station.

DISCHARGE MEASUREMENTS. Made by wading near gage, from cable 50 feet 

above gage, or, during extremely high stages, at Iron Bridge.

CHANNEL AND CONTROL. Bed of stream clean, smooth, solid roek, and permanent, except 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, both banks, which are dirt and wooded, subject to overflow. 

Rock ledge extending diagonally across stream just below gage serves as lowwater control.

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

recorder, 3.55 feet at 12.15 p. m. April 27 (discharge, 1,310 second-feet); 

minimum stage, 0.30 foot at 7 p. m. March 17 (discharge, 2.0 second-feet).

1915-1922: Maximum stage from water-stage recorder, 9.6 feet from 

2 to 6 a. m. September 25, 1919 (discharge, 13,000 second-feet). Minimum 

discharge less than 0.7 second-foot April 17, 1916.

ICE. None reported.

DIVERSIONS. Station is 2 miles below diversion of low-line (silt-line) canal of 

the Imperial Irrigation Co., 18J^ miles below diversion for the Imperial 

reservoir (17,000 acre-feet capacity), 25 J^ miles below diversion for Ward 

County Water Improvement District No. 2 (of which the old Grandfalls 

project is a part), and 4J^ 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 total number of acres declared irrigated in 

Texas above station to be1 about 58,000. The effect of diversion is somewhat counterbalanced by water returned to stream by seepage. The only 

diversion of importance below the 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 permanent for the year. Rating curve well 

defined from 2 to 15,000 second feet. Operation of water-stage recorder not 

satisfactory. Daily discharge determined by applying to rating table mean 

daily gage heights obtained from recorder graph by inspection or by use of 

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

fair.

PECOS RIVER HEAR SHEFFIELD, TEX.

LOCATION. At highway bridge on Fort Stockton-Ozona road, 3% miles east 

of Sheffield, Pecos County, 41 miles west of Ozona, 60 miles downstream 

from Buena Vista, and 76 miles east of Fort Stockton.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 10, 1921, to September 30, 1922.

GAGE. Chain gage attached to upstream side of bridge. Auxiliary staff gage1 

attached to pier near left bank; read by R. C. St. Clair, H. B. Smith, or 

Kyle Smith.

DISCHARGE MEASUREMENTS. Made from bridge or from wading near bridge.

CHANNEL AND CONTROL. Composed of silt, sand, and gravel; shifts. Right 

bank is not overflowed; left bank is overflowed during extremely high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during period of record 

4.95 feet at 9 a. m. Mar. 25 (discharge, 1,820 second-feet, determined from 

extension of rating curve and subject to error); minimum stage, 1.84 feet 

from 7 a. m. to 6 p. m., September 17 (discharge, 28 second-feet, determined 

from extension of rating curve and subject to error).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Station is below all diversions. During much of the time practically the only flow past the station is waste and seepage water from the 

irrigated area above.

REGULATION. Flow partly regulated by storage and diversion dams in New 

Mexico and Texas.

ACCURACT. Stage-discharge relation not permanent. Curve fairly well defined 

from 100 to 700 second-feet, and extended above and below this to cover 

the range of stage. Gage read twice daily to hundredths, October 10 to 

February 10 and June 18 to September 30, and once daily to hundredths 

the remainder of the time, when read. Daily discharge determined by 

indirect method for shifting control, except as noted in footnote to dailydischarge table. Records fair.

SURFACE WATER SUPPLY, 1922, PART VIII

PECOS KIVEE NEAK COMSTOCK, TEX.

LOCATION. At Pecos High Bridge of Galveston, Harrisburg & San Antonio 

Railway Co., 11 miles west of Comstock, Val Verde County, 18 miles east of 

Langtry, and 14 miles by stream above confluence with Rio Grande; below 

all tributaries.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 1, 1900, to September 30, 1922. (Also gage heights 

for 1898.)

GAGE. Vertical staff attached to downstream side of bridge pier on left bank; 

read by W. A. Clare.

DISCHARGE MEASUREMENTS. Made from cable 1,000 feet above bridge.

CHANNEL AND CONTROL. Banks and stream bed composed of rock and gravel j 

water flows through a series of rapids and pools in a canyon approximately 

300 feet deep; banks not subject to overflow. Stage-discharge relation at 

low stages changes slightly.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 27.16 feet at 

noon June 18 (discharge not determined); minimum stage, 0.30 foot 8 a. m. 

to 5 p. m. September 6 (discharge, 220 second-feet).

1900-1922: Maximum stage recorded, 35.75 feet April 6, 1900 (discharge 

not determined); minimum discharge recorded, 106 second-feet July 29 to 

August 1, 1918.

ICE. None reported.

DIVERSIONS. Considerable water is diverted and stored above the station for 

irrigation. Lakes McMillan and Avalon of the Carlsbad project of the 

United States Bureau of Reclamation which have a combined capacity of 

58,500 acre-feet, are located on Peeps River a few miles above Carlsbad, 

N. Mex. In addition to the water stored in New Mexico, water from 

Pepos River is used to irrigate large areas of land near Barstow and Grandfalls, Tex. There are no diversions below the station. .Return waters tend 

to equalize effects 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 permanent during year. Rating curve 

well defined from 260 to 13,000 second-feet and fairly well defined to 40,000 

second-feet. Gage read to hundredths twice daily, but observer's work 

doubtful. Daily discharge determined by applying mean daily gage height 

to rating table. Records fair.
