SCOPE OP WORK

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

water year ending September 30, 1955. Since 1888, when the United States Geologies 

vey first studied streamflow in relation to problems of irrigation, similar measurements 

have been made at more than 13,250 gaging stations in the 48 States and at many others in 

the Territories of Alaska and Hawaii. On September 30, 1955, the Geological Survey and 

cooperating organizations were maintaining 6,860 gaging stations, including those in 

Alaska and Hawaii. Discharge measurements only were made at many other points in the 

1955 water year, most of which are published at the end of this report. The name of each 

stream measured at points other than gaging stations is not listed in the index to this 

report. Only the major river basins in which measurements were made are listed under the 

item "Discharge measurements" in the index.

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

DEFINITION OF TERMS AND ABBREVIATIONS

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

as follows:

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

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

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

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

is distributed uniformly in time and area.

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

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

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

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

for irrigation.
EXPLANATION OF DATA 3

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

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

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

Stage-discharge relation Is the relation between gage height and the amount of water 

flowing In a channel, expressed as volume per unit of time.

Control designates a feature downstream from the gage that determines the stagedischarge relation at the gage. This feature may be a natural constriction of the 

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

Contents Is the volume of water in a reservoir. Unless otherwise Indicated, volume Is 

computed on the basis of a level pool and does not Include bank storage.

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

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

Figures of drainage area given herein Include all closed basins, or noncontrlbutlng areas, 

within the area unless otherwise noted.

WSP Is used as an abbrlvlatlon for "Water-Supply Paper" In references to previously 

published reports. -

DOWNSTREAM ORDER OF LISTING GAGING STATIONS

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

order of listing gaglng-statlon records was changed. In this report, In a downstream direction along the main stem all stations on a tributary entering above a main-stem station 

are listed before that station. If a tributary enters between two main-stem stations, it 

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

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

which a gaging station is situated and the stream to which It is Immediately tributary, 

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

represents one rank. This downstream order and system of indention show which gaging 

stations are on tributaries between any two stations on a main stem and the rank of the 

tributary on which each gaging station is situated.

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

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

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

from source to mouth of the uppermost tributary to the tributary.

EXPLANATION OF DATA

i 

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

of discharge. In addition, observations of factors affecting the stage-discharge relation, weather records, and other information are used to supplement base data in determining the daily flow. The re'cords of stage are. obtained either from direct readings on 

a nonrecordlng gage or from a water-stage recorder that gives a continuous record of fluctuations. Measurements of discharge are made with a current meter by the general methods 

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

These methods are described in Water-supply Paper 888 and are also outlined in standard 

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

stations are shown in figure 1.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

used as a factor in the determination of discharge.

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

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

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

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

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

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

daily records is not changed.

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

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

runoff of the streaml Records are published for the water year which begins on October 1 

and ends on September 30. A calendar of the water year 1955 is shown on page IV for the 

purpose of finding the day of the week for any date.

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

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

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

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

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

Corps of Engineers unless otherwise noted. Under "Records available" are given the periods 

for which there are published records generally equivalent to those at the present site. 

Under "Gage" are given the type of gage currently in use and the datum of the present gage
6 SURFACE WATER SUPPLY, 1955, PART 8

above mean sea level, and a condensed history of the types, locations, and daturas of previous gages used during the period of records available. Under "Average discharge" is 

given the average discharge for the number of years indicated. It is not given for stations having fewer than five complete years of record or for stations where changes in 

water development during the period of record cause the figure to have little significance. 

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

there is little or no regulation; the minimum daily discharge if there is extensive regulation (also the minimum discharge if useful); and the minimum gage height (unless it is 

of no Importance). In the first paragraph, the data given are for the complete current 

water year unless otherwise specified. In the second paragraph, the data given are for the 

periods of record within the calendar year dates in the heading (not necessarily those for 

the complete years indicated by the heading dates). Reliable information concerning major 

floods that have occurred outside the period of record are given in the third or last paragraph under "Extremes." Unless otherwise qualified, the maximum discharge corresponds to 

the crest stage obtained by use of a water-stage recorder, a crest-stage indicator, or a 

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

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

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

station is given under "Remarks."

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

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

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

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

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

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

years only one number is given; for instance, 1933 stands for the water year October 1, 

1932, to September 30, 1933. If no daily, monthly, or annual figures of discharge are 

concerned in the revision, that fact is brought out by notations after the year dates as 

follows: "(M)" means that only the instantaneous maximum discharge was revised; "(m)" 

that only the instantaneous minimum was revised; and "(P)" that only peak discharges were 

revised. If the drainage area has been revised, the report in which the revised figure 

was first published is given. It should be noted that for all stations for which cubic 

feet per second per square mile and runoff in inches are published, a revision of the 

drainage area necessitates corresponding revision of all figures based on the drainage 

area. Revised figures of cubic feet per second per square mile and runoff in inches resulting from a revision of the drainage area only are usually not published in the annual 

series of reports.

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

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

not published for stations on canals.
ACCURACY OP FIELD DATA AND COMPUTED RESULTS 7

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

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

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

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

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

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

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

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

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

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

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

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

station description.

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

for each month are underlined. If the figure is repeated, it is underlined only on the 

first day of its occurrence.

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

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

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

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

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

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

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

usually less than 20 inches.

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

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

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

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

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

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

the peaks are subject to substantial control by man.

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

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

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

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

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

For most gaging stations on lakes and reservoirs the data presented comprise a description of the station and a monthly summary table of stage and contents. For some reservoirs 

a table showing daily contents or stage is given. A skeleton table of capacity at given 

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

but it is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of streamflow data depends primarily on (l) the stability of the stagedischarge relation or, if the control is unstable, the frequency of discharge measure4Z4841 O -57 -Z ;
8 SURFACE WATER SUPPLY, 1955, PART 8

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

The station description states the degree of accuracy of the records. "Excellent" indicates that, in general, the error in the daily records is believed to be less than 

5 percent; "good," less than 10 percent; "fair," less than 15 percent; and "poor," probably more than 15 percent. The records of monthly and yearly mean discharge and runoff 

are, in general, more nearly accurate than the daily records.

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

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

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

cubic feet per second per square mile and runoff in inches are not published unless storage or diversion records are included to indicate the extent of the regulation or diversion, or unless satisfactory adjustments can be made for changes in contents of reservoirs 

or for other changes incident to use and control. Evaporation from a reservoir is not included in the adjustments for changes in reservoir contents, unless it is so stated. Even 

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

when relatively large negative adjustments are made or when evaporation is large in comparison with the observed discharge.

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

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

because water must first be supplied to existing irrigation systems.

PUBLICATIONS

To facilitate publication of the annual series of reports, the area of the United 

States is divided into 14 parts whose boundaries coincide with certain natural drainage 

lines. Formerly, the results of streamflow measurements were published in 14 volumes, one

The records at most of the stations discussed in these reports extend over many years. 

Discharge measurements at many points other than regular gaging stations have been made 

each year and are published at the end of each report. The streams and points of measurement are listed in the same order as the streams and gaging stations in the body of 

the report. An index of the records obtained before 1904 has been published in WaterSupply Paper 119.

Bach of the reports on the surface-water supply for the year 1939 (Water-Supply Paper
PUBLICATIONS 11

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

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

record had been collected. These summaries were reprinted separately.

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

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

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

for Western Gulf of Mexico basins.

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

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

The Agricultural Research Service of the United States Department of Agriculture has been collecting records of runoff near Waco, Tex., from 3 areas of less than 200 acres each beginning in 1938, 

from 2 areas of about 4 acres and 10 areas of 20 to 1,100 acres, from 1938-43 and 1946-55, and near 

Albuquerque, N. Mex., beginning in 1938, from 3 areas of less than 180 acres.

HYDROLOGIC CONDITIONS

The water year 1955 was characterized by deficient runoff over most of area covered by 

this report except for Louisiana where runoff was well above median. Drought conditions 

that existed over much of the area were Interrupted by moderate to severe flooding in 

scattered areas during the water year. Outstanding floods occurred in the Pecos River 

basin in New Mexico during October; runoff at the key gaging station Bayou Nespique near 

Basile, La. was record-high for the month of February; high floods occurred in Louisiana 

during April and May from heavy rains that measured up to 12f inches on May 19-20; heavy 

flash floods occurred in New Mexico throughout July, August, and September, with Albuquerque receiving damaging floods July 27 and September 24; floods in several areas of Texas 

during September produced record-high flows on Nueces River at Laguna, Double Mountain, and 

Salt Porks Brazos River near Aspermont and at other gaging stations-some were the highest 

known in at least 55 years. For three key gaging stations, a comparison of the monthly 

and yearly mean discharges during the 1955 water year with the median for the 25-year 

period (1921-45) is shown in figure 3 on the following page.

Jan. 17, 1940, wire-weight gage at same site and datum. Auxiliary water-stage recorder 

1.8 miles downstream. Oct. 1, 1943, to Nov. 1, 1950, auxiliary staff gage at same site 

and datum.

Average discharge. 17 years, 262 cfs (189,700 acre-ft per year).

Extremes. Maximum discharge during year, 10,200 cfs Feb. 7 (gage height, 21.21 ft); no 

flow at times.

1938-55: Maximum discharge, 11,900 cfs May 20, 1953 (gage height, 22.36 ft); no 

flow at times in 1939, 1948, 1955.

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

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

24 CALCASIEU RIVER BASIN

Calcasieu River near Kinder, La.

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

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

Whiskey Chitto Creek and 4 miles west of Kinder.

Drainage area. 1,700 sq mi.

Records available.--August 1922 to January 1925, October 1938 to September 1955.

Sage. Water-stage recorder. Datum of gage is 11.95 ft above mean sea level, datum of 

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

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

1939, wire-weight gage at present site and datum.

Average discharge. 19 years (1922-24, 1938-55), 2,883 cfs (2,087,000 acre-ft per year).

Extremes. Maximum discharge during year, 40,100 cfs Feb. 8 (gage height, 20.80 ft); minimum, 211 cfs (regulated) Oct. 8 (gage height, 2.41 ft).

1922-25, 1938-55: Maximum discharge, 182,000 cfs May 19, 1953 (gage height, 32.00 

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

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

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

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

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

rice, part of which is below station. The maximum rate of withdrawal is about 100 cfs 

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

TRINITY RIVER BASIN 69

West Fork Trinity River at Fort Worth, Tex.

Location (revised) . Lat 32°46', long 97°20', on left bank 200 ft downstream from Clear 

Fork Trinity River, 950 ft upstream from Texas Electric Service Co.'s concrete dam, 

1,000 ft upstream from Paddock Viaduct (North Main Street) at Fort Worth, Tarrant 

County, and at mile 559.

Drainage area. 2,627 sq mi.

Records available. October 1920 to September 1955. Gage-height records collected in 

this vicinity since 1910 are contained in reports of U. S. Weather Bureau.

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

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

Geodetic Survey datum). Prior to Aug. 21, 1954, water-stage recorder at site 850 ft 

downstream at same datum.

Average discharge. 35 years, 420 cfs (304,100 acre-ft per year), unadjusted.

Extremes. Maximum discharge during year, 1,360 cfs May 19 (gage height, 3.32 ft); minimum daily, 0.7 cfs Aug. 2-4, Sept. 7. 8.

1920-55; Maximum discharge, 85,000 cfs Apr. 25, 1922 (gage height, 23.95 ft), by 

slope-area determination of peak flow by city engineer of Port Worth; maximum cage 

height, 25.91 ft May 17, 1949 (discharge, 64,300 cfs); no flow at times. 

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

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

Plow largely regulated by Bridgeport Reservoir since 1932 [see p. 60), Eagle Mountain 

Reservoir since 1934 (see p. 63), Benbrook Reservoir since 1952 (see p. 65), and Lake 

Worth (capacity, 33,300 acre-ft). During the year, the City of Fort Worth diverted 

50,780 acre-ft of water from Lake Worth for municipal use and returned 30,530 acre-ft 

of sewage effluent below station. Several small diversions above station.

Revisions.--WSP 1148: Drainage area. Revised figures of discharge, in cubic feet per 

second, for high-water period In the water year 1925, superseding those published in 

WSP 608, are given herewith:

Lake Dallas near Lake Dallas, Tex.

Location. Lat 33°07', long 96°59', in gatehouse at Garza Dam on Elm Pork Trinity River, 

1.6 miles upstream from Little Elm Creek and 2.0 miles southeast of town of Lake 

Dallas, Denton County.

Drainage area. 1,165 sq mi.

Records available. December 1928 to September 1955.

Gage. Water-stage recorder. Datum of gage is 0.08 ft above mean sea level, datum of 

1929. Prior to Jan. 6, 1943, staff gages at several sites in vicinity of present gage 

at same datum.

Extremes. Maximum contents during year, 128,000 acre-ft June 23 (gage height, 522.2 ft); 

minimum, 56,100 acre-ft Dec. 22-26 (gage height, 512.6 ft).

1928-55: Maximum contents not determined; maximum gage height, 534.0 ft Apr. 25, 

1942, from floodmarks (all gates were open during passing of crest through lake); 

minimum contents observed, 19,220 acre-ft Nov. 22, 1952 (gage height, 503.2 ft).

Remarks.--Reservoir is formed by earthen hydraulic-fill dam, consisting of 567 ft of 

concrete service spillway and 2 dikes. There are two emergency earthen spillways 

beyond right end of dam. Dam completed in November 1927 and storage began Feb. 16, 

1928. Capacity, 156,600 acre-ft (gage height, 525.0 ft. top of service spillway). 

Water can be withdrawn through one 18-inch outlet gate (gage height of bottom of gate, 

474.0 ft), four 48-inch outlet gates (gage height of bottom of gate, 463.0 ft), and 

one 6-inch gate (gage height of bottom of gate, 474.0 ft). Dead storage is negligible. 

Water is used by city of Dallas for municipal supply. Since Feb. lj 1954, the city of 

Dallas has at times operated 6 pumps (total capacity, about 120 cfs) to divert water 

from Red River into Lake Dallas. See record for Elm Fork Trinity River near Sanger 

(p. 71 ). Figures given herein represent total contents.

TRINITY RIVER BASIN

Trinity River at Dallas, Tex.

Location. Lat 32°47', long 96°48', on left bank on downstream side of left pier of Commerce Street viaduct at Dallas, Dallas County, 5^ miles downstream from confluence of 

West and Elm Porks, and at mile 500,

Drainage area. 6,120 sq mi. Records available. October 1898 to December 1899 (gage heights only, in WSP 28, 37), 

July 1903 to September 1955 (January 1907 to September 1920 monthly records only, in 

WSP 850). Gage-height records collected in this vicinity since 1903 are contained in 

reports of the U. S. Weather Bureau. Gage. Water-stage recorder. Datum of gage is 368.02 ft (corrected) above mean sea level,

"datum of 1929, supplementary adjustment of 1954. Oct. 1, 1898, to Dec. 31, 1899,

sliding pointer at site 2 miles upstream at different datum. July 1, 1903, to July 20, 

1930, chain gage at present site and datum. July 21, 1930, to Sept. 30, 1932, chain 

gage at site 6 miles downstream at datum 3.08 ft lower.

Average discharge. 52 years (1903-55), 1,480 cfs (1,071,000 acre-ft per year).

Extremes. Maximum discharge during year, 6,010 cfs May 20; maximum gage height, 26.76 ft 

May 20; minimum discharge, 36 cfs Sept. 7 (gage height, 11.83 ft); minimum daily, 45 

cfs Sept. 7. 1903-55: Maximum discharge, 184,000 cfs May 25, 1908 (gage height, 52.6 ft), from 

rating curve extended above 109,000 cfs; minimum observed for periods 1903-6, 1920-55, 

1.2 cfs July 4, 1953. Maximum stage known since at least 1840, that of May 25, 1908. Flood in 1866 

reached about same stage. Remarks . Records good except those for period of rapidly changing stage, which are fair. 

Flow largely regulated by Bridgeport Reservoir since 1932 (see p. 60 ), Eagle Mountain 

Reservoir since 1934 (see p. 63 ), Benbrook and Grapevine Reservoirs since 1952 (see 

p. 65, 80 ), Lake Dallas since 1928 (see p. 74 ), Garza-Little Elm Reservoir since 

1954 (see p. 75), and several smaller reservoirs, all of which have a combined capacity of 2,128,000 acre-ft. During the year the city of Dallas diverted 77,000 acre-ft of 

water above the station for municipal use and returned 59,500 acre-ft of sewage effluent 

below station. Sewage effluent from the cities of Fort Worth, Arlington, and Grand 

Prairie enters above the station.

Revisions (water years). WSP 850: 1903-6 (,monthly and annual means). WSP 1148: Drainage area.

Rating table, water year 1954-55, except period when rate of change in stage was

a factor (gage height, in feet, and discharge, in cubic feet per second)

(Shifting-control method used June 17, 18, June 21 to Sept. 30)

Location.--Lat 32°25'40", long 96 0 27'50", on left bank at downstream side of left pier of 

bridge on State Highway 34, 2.5 miles south of Rosser, Kaufman County, 8.5 miles downstream from East Fork Trinity River, and at mile 451.

Drainage area.--8.162 sq mi.

Records available.--July 1924 to September 1925 (October 1924 to September 1925, gage 

heights only), November 1938 to September 1955.

. Water-stage recorder. Datum of gage is 302.65 ft above mean sea level, datum of 

'929. July 25, 1924, to Sept. 30, 1925, staff gage at abandoned lock and dam No. 7, 

1.7 miles upstream at datum 6.94 ft higher.

Average discharge.--16 years (1939-55), 2,780 cfs (2,013,000 acre-ft per year).

Extremes. Maximum discharge during year, 6,060 cfs May 21 (gage height, 21.09 ft); minimum, 116 cfs Oct. 19.

1924, 1938-55: Maximum discharge not determined, occurred Apr. 23 or 24, 1942, 

following numerous breaks in levee system on both banks; maximum gage height, 41.55 ft 

Apr. 22, 1942, just prior to levee breaks; maximum daily discharge, 133,000 cfs Apr. 23. 

1942; minimum, 34 cfs Sept. 8-11, 1924.

Flood in May 1908 reached a stage of about 33 ft, present site and datum, from information by Corps of Engineers (discharge believed to have been about the same as that 

of Apr. 23 or 24, 1942).

Remarks. Records good. Flow largely regulated by reservoirs above Dallas and after September 1953 by Lavon Reservoir on East Fork Trinity River (see p. 92). Levee system 

constructed in 1916. Cities of Fort Worth and Dallas diverted considerable water for 

municipal supply, of which about 60 percent is returned as sewage. Several small diversions on West Fork above Fort Worth. Records of chemical analyses and water temperatures for the water year 1955 are published in WSP 1402.

Bend County, 4.8 miles (2.7 miles by reservoir) upstream from Mason Creek, 9.0 miles 

(6.4 miles by reservoir) upstream from reservoir outlet works.

Drainage area. 150 sq mi at outlet works; 105 sq mi at upper gage. 

Records available. August 1945 to September 1955.

s. Water-stage recorders. Datum of both gages is 0.33 ft below mean sea level, datum 

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

Extremes. Maximum gage height at dam during year, 83.7 ft Feb. 8 (contents, 419 acre-ft); 

maximum at upper gage, 97.0 ft Feb. 6, 7.

1945-55: Maximum gage height at dam, 90.4 ft Aug. 30, 1945 (contents, 11,240 acreft); maximum at upper gage, 98.6 ft Aug. 28, 1945.

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

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

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

is operated for flood protection of city of Houston. It is a detention reservoir, with 

no provision for permanent storage. Outlet works consist of 5 concrete conduits, 2 of 

which are uncontrolled. The middle conduit is controlled by 2 vertical-lift steel 

gates; the 2 outer conduits are controlled by single vertical-lift steel gates. All 

gates remain closed except during recession of large floods or during emergencies. 

Capacity, 127,900 acre-ft between gage heights 75.0 ft (bottom of conduits) and 

101.9 ft (top of design flo'od pool). No constructed emergency spillways; runoff considerably in excess of designed capacity will be discharged around ends of dam. Gage 

heights and contents not published for floods that do not produce a gage height of 

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

irrigation season), April 1947 to September 1955.

B. Water-stage"1 recorder. Datum of gage is 29.93 ft above mean sea level, datum of 

T929, Houston supplementary adjustment of 1943. Prior to June 9, 1948, staff gage and 

June 9, 1948, to Apr. 22, 1952, water-stage recorder, at same site at datum 5.80 ft 

higher.

Extremes. Maximum discharge during year, 1,350 cfs Feb. 6 (gage height, 14.00 ft); no 

flow at times.

1947-55: Maximum discharge, 1,840 cfs Oct. 8, 1949 (gage height, 18.98 ft, present 

datum); no flow at times.

Maximum stage known since 1932, that of Oct. 8,'1949.

Revisions.--The maximum discharge for the water year 1947 has been revised to 710 

cfs Aug. 25, 1947 (gage height, 10.10 ft), superseding figure published in WSP 1088.

20 cfs, which are fair. Diversions for irrigation above station. Large area of rice 

land above station is irrigated with water from Brazos River. Low flow from April to 

October is largely drainage from irrigated lands.

Note. Discharges, in cubic feet per second, for some days in water years 1944 and 

1946, not previously published because stage exceeded limits of rating, have been computed on basis of later ratings and are given herewith:

124 OYSTER CREEK BASIN

Oyster Creek near Angleton, Tex.

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

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

Missouri Pacific Railroad bridge, 4^ miles downstream from another Missouri Pacific 

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

Records available. October 1944 to September 1955.

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

"1929.

Average discharge. 10 years (1945-55), 139 cfs (100,600 acre-ft per year).

Extremes. Maximum discharge during year, 532 cfs Feb. 7 (gage height, 16.12 ft); minimum 

daily, 0.3 cfs May 9, 10.

1944-55: Maximum discharge, 2,320 cfs Oct. 12, 1949 (gage height, 28.92 ft); minimum daily, that of May 9, 10, 1955.

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

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

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

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

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

Revisions. The maximum discharge for the water year 1947 has been revised to 1,790 

cfs Nov. 7, 1946 (gage height, 26.25 ft), superseding figure published in WSP 1088.

Remarks. Records good. Diversions above station for irrigation. A large part of the 

flow is water released from Harris Reservoir (capacity, 12,000 acre-ft), for industrial 

use below station. Harris Reservoir is supplied with water diverted from the Brazos 

River during periods of flood flow.

Revisions. Revised figures of discharge, in cubic feet per second, for high-water periods 

in the water year 1947, superseding those published in WSP 1088, are given herewith:

Remarks. Reservoir is formed by earth-fill dam with rock riprap face; dam completed and 

storage began in October 1938. Capacity, 69,550 acre-ft between gage heights 1.6 ft 

(sill of lowest outlet gate) and 54.0 ft (crest of spillway). Dead storage, 450 

acre-ft. Records given herein represent total contents. Water is used for municipal 

supply. Lake Abilene on Elm Creek, Lake Kirby on Cedar Creek, and Lake Lytle on 

Lytle Creek (combined capacity, 23,900 acre-ft) are smaller reservoirs above station 

in Elm Creek basin. During year city of Abilene diverted 10,250 acre-ft of water into 

reservoir by pumping from Clear Fork Brazos River at a site above station at Nugent. 

An undetermined amount of flood flow was diverted by gravity ditch from Deadman Creek 

into reservoir.

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

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

mile 667.

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

Records available. January 1924 to September 1955. Published as "near Mineral Wells" 

1924-33.

1929. Prior to Nov. 15, 1933, chain gage at site 19 miles downstream at datum 38.19 

ft lower.

Average discharge. 31 years (1924-55), 1,130 cfs (818,100 acre-ft per year).

Extremes. Maximum discharge during year, 51,800 cfs Sept. 27 (gage height, 20.53 ft); 

minimum daily, 12 cfs Feb. 10.

(see preceding page) and several smaller reservoirs in Clear Fork and other basins, 

having a combined capacity of about 915,000 acre-ft. Many small diversions above 

station for irrigation, municipal supply and oilfield operation.

BRAZOS RIVER BASIN 137

Brazos River near Glen Rose, Tex.

Location. Lat 32°15'40", long 97°41'50", on left bank 2 miles upstream from Paluxy Creek, 

2.4 miles downstream from bridge on U. S. Highway 67, 4 miles northeast of Glen Rose, 

Somervell County, and at mile 509.

Drainage area. 24,840 sq mi, approximately, of which 9,240 sq mi is probably noncontributing.

Records available. October 1923 to September 1955.

Gage.--Water-stage recorder. Datum of gage is 567.82 ft above mean sea level, datum of 

 T929. Prior to May 7, 1931, combination staff and inclined gage at site 300 ft downstream at same datum. Since Apr. 27, 1950, supplementary water-stage recorder as 

flood gage 2.4 miles upstream at bridge on U. S. Highway 67.

Average discharge. 32 years, 1,479 cfs (1,071,000 acre-ft per year).

Extremes. Maximum discharge during year, 42,300 cfs Sept. 30 (gage height, 19.74 ft); 

minimum daily, 8.5 cfs May 9.

1923-55: Maximum discharge, 97,600 cfs May 18, 1935 (gage height, 23.68 ft), from 

rating curve extended above 68,000 cfs; no flow at times prior to construction of Possum Kingdom Dam.

Maximum stage known, about 30.0 ft May 8 or 9, 1922, from information by local 

residents.

Remarks. Records good except those for periods of backwater, which are fair. Plow since 

1941 largely regulated by Possum Kingdom Reservoir (see p. 134), except during major 

floods, and by several smaller reservoirs in Clear Pork and other basins, having 

a combined capacity of about 924,000 acre-ft. Many small diversions above station for 

irrigation, municipal supply, and oilfield operation.

Revisions (water years). WSP 1058: 1932.

Corps of Engineers). Nov. 2, 1916, to Sept. 30, 1922, staff gage at site If miles upstream at different datum. Oct. 1, 1922, to Apr. 8, 1926, chain gage at McCowan Bridge 

30 ft downstream at same datum. Apr. 9, 1926, to Oct. 9, 1933, chain gage at bridge on 

U.S. Highway 77, 2,020 ft downstream at datum 1.58 ft lower.

Average discharge. 38 years (1917-55), 1,731 cfs (1,253,000 acre-ft per year).

Extremes.--Maximum discharge during year, 10,200 cfs May 21 (gage height, 26.15 ft); minimum, 4.5 cfs Oct. 27.

1916-55: Maximum discharge, 647,000 cfs Sept. 10, 1921 (gage height, 53.2 ft, present datum, from floodmark), from rating curve extended above 90,000 cfs on basis of 

slope-area determination of peak flow; minimum, 0,3 cfs Oct. 29, 30, 1952.

Maximum stage known, that of Sept. 10, 1921; flood in 1852 reached about the same 

stage. Flood in December 1913 reached a stage of 49.0 ft. Stages based on information 

by local resident.

Remarks. Records fair. Many small diversions for irrigation and municipal supply affect 

very low flows. Some regulation by Belton Reservoir on Leon River beginning Mar. 8, 

1954 (see p. 149). Slight regulation by pumping above station.

Revisions (water years). WSP 718: 1918-22.

Location. Lat 29°46'20", long 96°02'10", near center of span at right side of pier of 

bridge on U. S. Highway 90, 200 ft downstream from Missouri-Kansas-Texas Railroad 

bridge, 1.3 miles downstream from Irons Creek, 5.0 miles southeast of San Felipe Post 

Office, Austin County, and at mile 142.

Drainage area.--43.690 sq mi, approximately, of which 9,240 sq mi is probably noncontributing.

Records available.--December 1938 to September 1955 (gage heights only, October 1945 to 

September 1953).

Gage.--Water-stage recorder. Datum of gage is 79.32 ft above mean sea level, datum of 

1929. Prior to Apr. 17, 1940, chain gage at site 200 ft upstream at same datum.

Average discharge.--8 years (1939-45, 1953-55), 8,776 cfs (6,354,000 acre-ft per year).

Extremes.--Maximum discharge during year, 19,600 cfs May 23 (gage height, 16.91 ft); minimum daily, 250 cfs Dec. 12.

1938-55: Maximum discharge, 152,000 cfs Nov. 25, 1940 (gage height, 41.10 ft); minimum daily, that of Dec. 12, 1954.

Maximum stage known, 49.0 ft Dec. 9, 1913, from information by local resident.

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

regulated by reservoirs above Bryan (see Brazos River at Waco and near Bryan). Many 

small diversions above station for irrigation, municipal use, and oilfield operation.

Discharge, in cubic feet per second, water year October 1954 to September 1955

160 BRAZOS RIVER BASIN

Brazos River at Richmond, Tex.

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

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

New Orleans Railroad bridge and at mile 93.

Drainage area. 44,050 sq mi, approximately, of which 9,240 sq mi is probably noncontributing.

Records available.--January 1903 to June 1906 and October 1922 to September 1955 in reports 

of Geological Survey. Published as "at Rosenberg" October 1922 to September 1931 and 

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

1901 and June to September 1902 in U. S. Department of Agriculture, Office of Experiment 

Stations, Bulletins Hos. 119 and 133. Gage-height records collected in this vicinity 

since 1914 are contained in reports of U. S. Weather Bureau.

Gage. Water-stage recorder and wire-weight gage. Datum of gage is 40.94 ft above mean 

sea level, datum of 1929, Houston supplementary adjustment of 1943. June to November 

1901, June to September 1902, and January 1903 to June 1906, various types of nonrecording gages at railroad bridge 925 ft upstream at different datums. Oct. 1, 1922, 

to Sept. 30, 1931, chain gage at Rosenberg 7.6 miles upstream at datum about 4 ft higher.

Average discharge.--35 years (1903-5, 1922-55), 7,173 cfs (5,193,000 acre-ft per year).

Extremes.--Maximum discharge during year, 19,300 cfs May 23 (gage height, 12.76 ft); minimum daily, 281 cfs May 11.

1903-6, 1931-55: Maximum discharge, 117,000 cfs Nov. 28, 1940 (gage height, 38.40 

ft); minimum daily, 35 cfs Aug. 23, 1934.

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

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

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

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

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

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

Remarks.--Records good. Flow regulated by reservoirs above Bryan. Considerable water 

diverted above station for irrigation and municipal supply materially affect low flows. 

Records of chemical analyses and water temperatures for the water year 1955 are given 

in WSP 1402.

Revisions.--Figure of daily discharge for Dec. 1, 1932, published in WSP 748, is in error. 

The correct figure is 972 cfs.

Discharge, In cubic feet per second, water year October 1954 to September 1955

Houston supplementary adjustment of 1943.

Average discharge.--6 years, 2,765 cfs (2,002,000 acre-ft per year).

Extremes. Maximum discharge during year, 19,100 cfs May 24; maximum gage height, 32.42 

ft Feb. 8; no flow May 8-11 due to pumping.

1949-55: Maximum discharge, 76,300 cfs May 19, 1953; maximum gage height, 55.49 ft 

May 20, 1953; no flow at times due to pumping.

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

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

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

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

in July 1899 was probably exceeded only by the flood in 1913.

Remarks. Records good. Flow regulated by reservoirs above Bryan. Considerable water 

diverted above station for irrigation and municipal supply. The Briscoe Irrigation Co. 

and the South Texas Water Co. have permits to divert a maximum of 600 and 400 cfs, 

respectively, above station for irrigation, industrial, and municipal supply.

174 COLORADO RIVER BASIN

Colorado River at Balllnger, Tex.

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

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

Creek and at mile 659.

Drainage area. 16 .840 sq mi, approximately, of which 11,600 sq mi is probably noncontributing.

Records available. June 1907 to September 1955 (June 1907 to November 1915 monthly records only, published in WSP 850). Gage-height records collected in this vicinity from 

1903-29 are contained in reports of U. S. Weather Bureau.

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

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

within 1 mile of present site at various daturas.

Average discharge. 48 years, 373 cfs (270,000 acre-ft per year).

Extremes. Maximum discharge during year not determined, occurred May 19; maximum gage 

height, 21.50 ft May 19, (backwater from Elm Creek); no flow at times.

1907-55: Maximum discharge, 75,400 cfs Sept. 18, 1936 (gage height, 28.6 ft); no 

flow at times.

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

datum, from information by local residents. Flood of Aug. 6, 1906, reached a stage of 

about 32.0 ft, present site and datum, from floodmarks (backwater from Elm Creek).

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

from Elm Creek, which are poor. Small diversions above station for irrigation affect 

low flow. Flow slightly regulated by Lake Colorado City (see p. 170), and since July 

1952 by Lake J. B. Thomas (capacity, 204,000 acre-ft).

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

on U. S. Highway 83, 0.2 mile north of Paint Rock, Concho County, and 2 miles downstream from Kickapoo Creek.

Drainage area. 5.538 sq mi, of which 275 sq mi is probably noncontributing. 

Records available. September 1915 to September 1955.

Gage. Water-stage recorder with masonry dam as control. Datum of gage is 1,574.43 ft 

above mean sea level, datum of 1929. Prior to Sept. 16, 1920, staff gage, and 

Sept. 17, 1920, to Sept. 17, 1936, water-stage recorder, at site 1.4 miles upstream 

at datum 13.16 ft higher. Oct. 2, 1936, to May 18, 1938, staff gage at site 1,000 ft 

downstream at same datum. May 19, 1938, to Jan. 14, 1940, wire-weight gage at same 

site and datum.

Average discharge. 40 years, 213 cfs (154,200 acre-ft per year).

Extremes. Maximum discharge during year, 24,100 cfs May 17 (gage height, 22.75 ft)- no 

flow at times.

1915-55: Maximum discharge, 301,000 cfs Sept. 17, 1936 (gage height, 43.4 ft from 

floodmarks), from rating curve extended above 85,000 cfs on basis of slope-area determinations at gage heights 35.8 and 43.4 ft; no flow at times.

Flood in August 1882 reached a stage of about 39.9 ft and flood in August 1906 

reached a stage of 39.5 ft, from information by local resident.

Remarks. Records good except those for periods when stage was below Crest of dam, which 

are poor. Many diversions above station for irrigation and municipal supply. Flow 

slightly regulated by Lake Nasworthy on South Coneho River (see p. 180), and by San 

Angelo Reservoir on North Concho River (see p. 183).

County, 6 miles downstream from Salt Creek, and 10 miles downstream from Brownwood 

Reservoir.

Drainage area. 1,614 sq mi.

Records available. May 1917 to June 1918, October 1923 to September 1955.

Gage. Water-stage recorder above spillway of city dam. Datum of gage is 1,318.58 ft 

above mean sea level, datum of 1929. May 25 to June 4, 1917, staff gage at dam 2,000 

ft downstream at datum 2.45 ft lower. June 8, 1917, to June 30, 1918, and Oct. 16, 

1923, to July 10, 1929, staff gage at site 1,300 ft downstream at different daturas.

Average discharge. 30 years (1924-28, 1929-55), 161 cfs (116,600 acre-ft per year).

Extremes. Maximum discharge during year, 7,240 cfs Sept. 23 (gage height, 7.77 ft); minimum, 0.1 cfs at times.

1917-18, 1923-55: Maximum discharge, 52,700 cfs Oct. 14, 1930 (gage height, 16.92 

ft), from rating curve extended above 38,000 cfs- no flow at times.

Maximum stage known, 21.7 ft in September 1900, from information by Gulf, Colorado 

and Santa Pe Railway Co. Flood of July 3, 1932, probably the greatest known, reached 

a discharge of about 235,000 cfs as it entered Brownwood Reservoir (computed from rate 

of change of contents in reservoir; data furnished by engineers of Brown County Water 

Improvement District No. 1).

Remarks. Records good. Plow largely regulated by Brownwood Reservoir (see p. 199). Diversion at Brownwood Reservoir, 10 miles upstream (see records for Brown County Water

("levels by Lower Colorado River Authority) .

Extremes . Maximum contents observed during year, 1,006,000 acre-ft May 21 (gage height, 

1,020.6 ft); minimum observed, 735,000 acre-ft May 8 (gage height, 1,008.0 ft).

1937-55: Maximum contents observed, 1,006,000 acre-ft May 15, 1954, May 21, 1955; 

minimum after filling of reservoir in July 1938, 340,800 acre-ft Sept. 8-10, 1952 (gage 

height, 983.4 ft).

Remarks. --Reservoir is formed by 2 reinforced concrete multiple-arch sections, 3 banks of 

taintor gates, and a 1,088-foot reinforced concrete spillway section. Dam completed 

and storage began May 20, 1937. Total capacity, 992,000 acre-ft (gage height, 1,020.0 

ft, top of spillway section). Usable capacity for power development, 955,000 acre-ft 

between gage height 937.0 ft (sill of powerhouse penstock) and 1,020.0 ft (top of 

spillway section). Water below gage height 937.0 ft can be withdrawn through two 

5-foot Bunger gates (emergency) down to gage height of 890.0 ft. Figures given herein 

represent total contents. Water used for power development and irrigation of rice on 

several districts below Columbus.

Barton Springs at Austin, Tex.

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

Creek for a distance of 1,000 ft in Zilker Park at Austin, Travis County. The main 

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

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

from mouth of Barton Creek.

Records available.--November 1894 to September 1955 (discharge measurements only). Summary of all discharge measurements prior to October 1937 is contained in WSP 850. 

Daily discharge record of Barton Creek at Austin, published for period April 1917 to 

September 1918, closely represents the flow of Barton Springs.

Extremes.--Maximum discharge measured during year, 22.0 cfs Nov. 17; minimum measured, 

13.8 cfs Aug. 30.

1894-1955: Maximum discharge measured, 166 cfs May 10, 1941; minimum measured, 

10.9 cfs Jan. 20, 1952.

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

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

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

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

by swimming pool at main spring being full has an appreciable effect on flow of springs.

GUADALUPE RIVER BASIN 233

San Antonio River at San Antonio, Tex.

Location. Lat 29°24 I 35", long 98°29'40", on right bank at downstream side of South Alamo 

Street Bridge, in San Antonio, Bexar County, 2.1 miles upstream from San Pedro Creek.

Drainage area. 42 sq mi, approximately. Normal flow of river comes from springs; drainage

area of stream not applicable.

Records available . January 1915 to November 1929, February 1939 to September 1955. Estimated monthly ground-water discharge contained in WSP 773-B and Texas Board of Water 

Engineers Report for Bexar County dated May 1947.

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

1929. Jan. 26, 1915, to Feb. 27, 1916, staff gage at site 2.2 miles upstream at different datum. Feb. 28, 1916, to Apr. 7, 1920, staff gage at site 1.9 miles upstream at 

different datum.

Average discharge. 30 years (1915-29, 1939-55), 59.5 cfs (43,080 acre-ft per year).

Extremes . Maximum discharge during year, 810 cfs Feb. 4 (gage height, 5.23 ft); minimum 

 daily, 0.6 cfs Mar. 30.

1915-29, 1939-55: Maximum discharge, 15,300 cfs Sept. 10, 1921 (gage height, 20.14 

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

Maximum stage known since at least 1819, that of Sept. 10, 1921; flood of July 5, 

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

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

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

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

artesian wells. Springs emerged from Edwards limestone in Balcones fault zone. Diurnal fluctuation caused by industrial pumping from wells (depleting the underground 

reservoir) above station.

in cubic feet per second) 

(Shifting-control method used Mar. 11-31)

GUADALUPE RIVER BASIN 237

Medina River near San Antonio, Tex.

Location. Lat 29°15', long 98°28', near left bank on downstream side of pier of bridge 

on U. S. Highway 281, 5.2 miles upstream from mouth and 9 miles south of San Antonio, 

Bexar County.

Drainage area. 1.225 sq mi (587 sq mi is above dam forming Medina Lake).

Records available. October 1929 to December 1930, July 1939 to September 1955. October 

1929 to December 1930. records below about 50 cfs in connection with seepage investigation (published as at Losoya").

Gage. Water-stage recorder. Datum of gage is 439.0 ft above mean sea level (levels by 

Corps of Engineers). October 1929 to December 1930, staff gage at Losoya, 1.5 miles 

downstream, at different datum.

Average discharge. 16 years (1939-55), 93.8 cfs (67,910 acre-ft per year).

Extremes. Maximum discharge during year, 1,200 cfs Feb. 6 (gage height, 11.35 ft); minimum daily, 4.8 cfs July 19, 20.

1939-55: Maximum discharge, 31,800 cfs Aug. 29, 1946; maximum gage height, 41.57 

ft Sept. 27, 1946 (backwater from San Antonio River); minimum daily discharge, 4.3 cfs 

Sept. 4, 5, 1952.

Maximum stage known, about 55 ft sometime prior to construction of Medina Dam in 

1913, from information by State Highway Department.

Remarks. Records good. Flow slightly regulated by Medina Lake (see p. 235), 60 miles upstream, and diversion dam reservoir (capacity, 4,500 acre-ft). Although the irrigation 

district has a permit to divert 300,000 acre-ft of water to irrigate 150,000 acres of 

land, there was little water available for irrigation during current year due to severe 

drought. A considerable part of the low flow is sewage from San Antonio which is released from Mitchell Lake, and waste water from Kelly Field which enters via Leon Creek.

262 NUECES RIVER BASIN

Nueces River near Three Rivers, Tex.

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

Dvalde & Gulf (Missouri Pacific) Railroad bridge, half a mile downstream from Prlo 

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

Drainage area. 15,600 sq ml.

Records available. July 1915 to September 1955. U.S. Weather Bureau has collected gageheight records In this vicinity since 1922.

Gage. Water-stage recorder and concrete control. Datum of gage Is 101.13 ft above mean 

sea level, datum of 1929, Houston supplementary adjustment of 1943. Prior to Apr. 5, 

1932, staff gage at railroad bridge 100 ft upstream at same datum.

Average discharge. 38 years (1915-18, 1920-55), 766 cfs (554,600 acre-ft per year).

Extremes.--Maximum discharge during year, 2,890 cfs May 14 (gage height, 14.31 ft); no 

flow July 7-11.

1915-55: Maximum discharge observed, 85,000 cfs Sept. 18, 1919 (gage height, 46.0 

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

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

Remarks. Records excellent. Part of flow of Nueces and Frlo Rivers and their headwater 

tributaries enters Edwards limestone In Balcones fault zone which crosses basin Just 

north of Uvalde. At low stages most of headwater flow enters this formation. Diversions above station for Irrigation. Records of the Lower Nueces River Water Supply 

District Indicate that during the water year an average of about 10 cfs was discharged 

from several artesian wells Into the Atascosa River upstream from this station to supplement the supply for the city of Corpus Chrlstl.

Revisions (water years). WSP 548: 1920-21.

NUECES RIVER BASIN 263

Lake Corpus Christ! near Mathis, Tex.

Location. Lat 28°02'52", long 97 C52'16" (revised), near left end of Mathis Dam on Nueces 

River, three-quarters of a mile upstream from bridge on U. S. Highway 96, 4 miles southwest of Mathis, San Patricio County, and at mile 48.

Drainage area. 16.656 sq mi.

Records available. September 1948 to September 1955. The Soil Conservation Service, 

U. S. Department of Agriculture, in cooperation with Texas Board of Water Engineers, 

has collected fragmentary gage-height records in connection with sedimentation studies 

since February 1942.

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

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

first buttress wall of left taintor gate was probably used.

Extremes. Maximum contents observed during year, 41,440 acre-ft May 22-24, June 3-6,

Sept. 13-15; maximum gage height, 74.45 ft June 5, 6; minimum contents observed, 20,160 

acre-ft May 10, 12, 13; minimum gage height, 69.15 ft May 12.

1948-55: Maximum contents observed, 57,000 acre-ft Apr. 30, 1949 (gage height, 

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

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

concrete service spillway 1,048 ft long, and 5 taintor gates, each 35 ft wide. Dam 

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

74 ft (top of taintor gates and service spillway). Dead storage is negligible. Reservoir used for municipal supply for city of Corpus Christ!. Water for city is released 

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

A siltation survey made by the Soil Conservation Service, U. S. Department of Agriculture, found the original capacity of the reservoir to have been 54,000 acre-ft, and 

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

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

crest.

Cooperation. Capacity curve furnished by Soil Conservation Service, U. S. Department of 

Agriculture. Records of daily gage heights furnished by city of Corpus Christ!.

Rio Grande at Otowi Bridge, near San Ildefonso, N. Mex.

Location. Lat 35°52'25", long 106 0 08'35", near right bank on downstream side of pier of 

former railway bridge, 400 ft downstream from bridge on State Highway 4, if miles southwest of San Ildefonso Pueblo, 2-| miles downstream from Pojoaque River (formerly known 

as Rio Pojoaque), and 7 miles west of Pojoaque.

Drainage area. 14.300 sq mi, approximately (includes 2,940 sq mi in closed basin in northem part of San Luis Valley, Colo.).

Records available. February 1895 to December 1905, June 1909 to December 1914, and October 

1930 to September 1955 in reports of Geological Survey. February 1895 to December 1905 

and June 1909 to December 1931 in reports of State engineer. In early reports this record was published as Rio Grande at Water Tank, as "at Rio Grande," and "near Buckman."

e_. Water-stage recorder. Datum of gage is 5,488.48 ft above mean sea level, datum of 

1929. Prior to May 19, 1904, and July 25 to Oct. I, 1904, staff gage at site 180 ft upstream at datum 2.02 ft lower. May 19 to July 24, 1904, Oct. 2, 1904, to Dec. 31, 1905, 

and June 23, 1909, to May 31, 1910, staff or chain gage at same site and datum.

Average discharge. 52 years (1895-1905, 1909-14, 1915-16, 1919-55), 1,627 cfs (1,178,000 

aere-ft per year).

Extremes. Maximum discharge during year, 5,140 cfs Aug. 21 (gage height, 6.28 ft); minimum daily, 220 cfs Sept. 23.

1930-55: Maximum discharge, 22,500 cfs May 16, 1941; maximum gage height, 13.70 ft 

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

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

State engineer for May 23, 1920.

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

which are poor. Discharge measurements generally made four times a month. Flow partly 

regulated by El Vado Reservoir (see p. 417) on Rio Chama which contributes about 40 percent of total flow. Diversions above station for irrigation of about 600,000 acres in 

Colorado and 75,000 acres in New Mexico. Records of chemical analyses, water temperatures, and sediment loads for the water year 1955 are given in WSP 1402.

Extremes. Maximum discharge during year, 1,020 cfs July 29; maximum gage height, 9.70 ft 

July 22; no flow at times.

1936-38, 1943-55: Maximum discharge, 15,300 cfs Oct. 18, 1944, from rating curve 

extended above 3,000 cfs by logarithmic plotting; maximum gage height, 5.62 ft Aug. 29, 

1943, site and datum then in use; no flow at times.

Remarks.--Records fair prior to Mar. 14, poor thereafter. Discharge measurements generally made eight times a month. Subsequent to October 1953, flow of this station can 

be completely regulated by Jemez Canyon Reservoir (see p. 417). However, reservoir 

is designed essentially for desilting and flood control rather than storage. Diversions for irrigation of about 3,000 acres above station. Records of water temperatures 

and sediment loads for the water year 1955 are given in WSP 1402.

Revisions (water years).--WSP 1178: 1949. WSP 1212: 1950.

b~y Corps of Engineers). October 1912 to December 1914 staff gage, January 1915 to 

Dec. 5, 1917, chain gage, and Dec. 6, 1917, to December 1926, staff gage, at same 

site at different datums.

Average discharge. 17 years (1914-25, 1949-55), 6.81 cfs (4,930 acre-ft per year).

Extremes . Maximum discharge during year, 224 cfs Aug. 11 (gage height, 3.20 ft); no 

now for long periods.

1912-26, 1949-55: Maximum discharge recorded, 1,760 cfs Aug. 28, 1952 (gage 

height, 5.35 ft, from rating curve extended above 300 cfs on basis of velocity area 

studies); no flow for long periods.

Remarks. Records good except those above 200 cfs, and those below 1 cfs, which are 

fair. Discharge measurements generally made twice a month. Flow regulated by 

Bluewater-Toltec Reservoir (capacity, 46,000 acre-ft). Diversions and ground-water 

withdrawals for irrigation of about 4,500 acres above station.

Drainage area. 2.610 sq mi, approximately. 

Records available. April 1943 to September 1955.

Gage. Water-stage recorder and concrete control. Datum of gage is 5,474.88 ft above mean 

sea level, unadjusted.

Average discharge. 12 years, 11.9 cfs (8,620 acre-ft per year).

Extremes. Maximum discharge during year, 7,150 cfs Aug. 11 (gage height, 11.1 ft); no 

flow for much of year.

1943-55: Maximum discharge, 8,010 cfs May 26, 1944; from rating curve extended 

above 1,700 cfs by logarithmic plotting; maximum gage height, 11.1'ft Aug. 11, 1955; no 

flow for long periods.

A stage of 15.4 ft (based on drift marks found near gage in 1950) probably occurred 

in flood of August 1929.

Remarks. Records good. Discharge measurements generally made three times a month. Plow 

partly regulated by Bluewater Reservoir (capacity, 46,000 acre-ft) and three small 

reservoirs below. Diversion for irrigation of about 8,600 acres above station 

(includes about 4,500 acres irrigated wholly or partly from ground-water sources). 

Records of water temperatures and sediment loads for the water year 1955 are given in 

WSP 1402.

on right bank 1 mile upstream from outlet to Rio Grande conveyance channel, 5 miles 

northeast of San Marcial, and 12 miles south of San Antonio.

Records available. March 1948 to September 1955.

Gage. Water-stage recorder and wooden control. Datum of gage is 4,489.12 ft above sea

ievel, datum of 1929.

Extremes. 1948-55: Maximum daily discharge, 180 cfs May 11, 1950; minimum daily, 1.0 cfs

 Nov. 12, 1953.

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

represents seepage from river and waste from wildlife refuge. Diversions for irrigation of a few hundred acres above station.

368 RIO GRANDE BASIN

Rio Grande conveyance channel below heading near San Marcial, N. Mex.

Location. Lat 33°44>, long 106°55', in sec. 36, T. 6 S., R. 1 W., on left bank 1,250 ft 

downstream from heading structure, 6 miles upstream from San Marcial, and 13.4 miles 

southwest of San Antonio, Socorro County.

Records available.--November 1953 to September 1955.

Gage. Water-stage recorder. Datum of gage is 4,475.42 ft above mean sea level (Bureau of 

Reclamation benchmark).

Extremes. Maximum daily discharge during year, 1,500 cfs July 29; no flow for several 

days.

1953-55: Maximum discharge, 1,670 cfs Sept. 28, 1954 (gage height, 5.42 ft); no 

flow at times.

Remarks. Records fair. Discharge measurements are generally made twice a week depending 

on rate of flow. Records of water temperatures and sediment loads for the water year 

1955 are given in WSP 1402. Discharge in the conveyance channel represents entire flow 

of Rio Grande below about 2,000 cfs, plus one small drain (1 to 2 cfs). Flows above 

2,000 cfs will bypass or breach earthen plug to main river channel (now called "floodway"). Conveyance channel is gated and was designed as a water salvage and ground-water 

intercept canal through the wide wooded valley; it is also gaged at the mouth of Nogal 

Canyon (see p. 370). Daily discharge for water year 1955 computed by subtracting daily 

mean discharge of San Antonio reverside drain near San Marcial from that of a supplementary gage on conveyance channel at Tiffany, 3.3 miles downstream. Records at 

another supplementary gage below San Marcial Lake are included in the total flow of Rio 

Grande at San Marcial (see following page).

370 RIO GRANDE BASIN

Rio Grande conveyance channel at mouth of Nogal Canyon, near Truth 

or Consequences, N. Mex.

Location. Lat 33°29', long 107°07", on downstream side of bridge about opposite mouth of 

Nogal Canyon and 25 miles northeast of Truth or Consequences (formerly Hot Springs) 

Sierra County.

Records available. November 1953 to September 1955.

Gage.--Water-stage recorder. Datum of gage Is 4,405.20 ft above mean sea level, datum of 

1929 (levels by Bureau of Reclamation).

Extremes. Maximum discharge during year, 1,770 cfs July 29 (gage height, 6.50 ft)- minimum dally, 14 cfs July 14.

1954-55: Maximum discharge, that of July 29 1955; minimum dally, 11 cfs July 15-21,

Remarks. Records good. Discharge measurements generally made 5 to 10 times a month.

Discharge in the conveyance channel represents flow of Rio Grande below about 2,000 cfs. 

The main river channel (now called "floodway") carries flow when gate-controlled Intake 

to conveyance channel is exceeded or when earthen plug Is breached or bypassed; It may 

also carry spring flow, leakage through continuous levee, or runoff from left bank 

caused by Infrequent local storms. Records are studied to assist In substantiating the 

objective of reducing losses caused by dispersed and meandering passage through several 

miles of bottom-land vegetation In the main channel.

Discharge, in cubic feet per second, water year October 1954 to September 1955

390 RIO GRANDE BASIN

Peoos River near Lake Arthur, N. Mex.

Location (revised) . Lat 32°59'18", long 104°19'20", in SW^NE^ see. 27, T. 15 S., R. 26 

E., on left bank 850 ft upstream from county bridge, 2? miles east of Lake Arthur, 

10 miles upstream from Cottonwood Creek, and 11 miles northeast of Artesia.

Drainage area. 14,760 sq mi, approximately (contributing area). 

Records available. August 1938 to September 1955.

Gage. Water-stage recorder and rock control. Datum of gage is 3,327.07 ft above mean 

sea level, datum of 1929.

Average discharge. 17 years, 331 cfs (239,600 acre-ft per year).

Extremes.--Maximum discharge during year, 26,700 cfs Oct. 7 (gage height, 20.60 ft); minimum daily, 1.8 cfs Sept. 2.

1938-55: Maximum discharge, 49,600 cfs Sept. 24, 1941 (gage height, 21.90 ft), 

from rating curve extended above 16,100 cfs on basis of slope-area determinations at 

gage height 21.77 ft and logarithmic plotting; no flow Aug. 21, 22, 1947, July 17, 

1953, July 29 to Aug. 1, Aug. 6, 7, 1954.

Flood of May 30, 1937, reached a stage of 21.77 ft (discharge, 51,500 cfs, by 

slope-area determination of peak flow), but may have been exceeded by floods of 1904 

and 1919.

Remarks. Records good except those for Oct. 7-11, Apr. 24 to May 8, and Sept. 26-30, 

which are fair. Discharge measurements made two or more times a month. Flow partly 

regulated by Alamogordo Reservoir 150 miles above station (see p. 418). Diversions 

and ground-water withdrawals for irrigation of about 98,500 acres above station.

Rating tables, water year 1954-55, except Oct. 7-12 (gage height, in feet, 

and discharge, in cubic feet per second)

Pecos River near Artesia, N. Mex.

Location. Lat 32°50'05", long 104°19'25", in w|HW^ sec. 18, T. 17 S., R. 27 E., near 

left bank on downstream end of bridge pier on State Highway 83, 4.3 miles east of 

Artesia, 7.0 miles north of mouth of Rio Penasco, and 17 miles north of McMillan Dam.

Drainage area. 15,300 sq mi, approximately (contributing area).

Records available . March 1905 to September 1925, October 1931 to February 1936 (published 

as "near Dayton"), and February 1936 to September 1955 in reports of Geological Survey. 

March 1905 to December 1931 in reports of State engineer.

Gage.--Water-stage recorder. Datura of gage is 3,291.05 ft (Bureau of Reclamation benchmark). Prior to Aug. 27, 1914, staff gage, and Aug. 27, 1914, to Feb. 21, 1936, waterstage recorder, at site 6j miles downstream at different datura. Feb. 21, 1936, to 

Apr. 4, 1941, water-stage recorder at site 600 ft downstream from present site at different datum.

Average discharge.--19 years (1936-55), 363 cfs (262,800 acre-ft per year).

Extremes. Maximum discharge during year, 25,200 cfs Oct. 8 (gage height, 13.76 ft); minimum daily, 3.6 cfs Sept. 1,3.

1905-55: Maximum gage height, 15.9 ft Sept. 18, 1919, site and datum then in use 

(discharge not determined). Flood of May 30, 1937, reached a gage height of 14.7 ft 

(discharge, 51,500 cfs, by slope-area method); no flow Aug. 17-24, 1934, Aug. 14-25, 

1946, Aug. 1-22, 1947, July 3-17, 1953, July 14 to Aug. 1, Aug. 5-7, 1954.

Remarks. Records good. Discharge measurements made 2 or more times a month. Flow partly 

regulated by Alamogordo Reservoir (see p. 418). Diversions and ground-water withdrawals 

for irrigation of about 128,000 acres above station. Discharge represents inflow to 

Lake McMillan, which is part of the storage system for the irrigation of about 25,000 

acres of Carlsbad project. Records of chemical analyses, water temperatures, and 

sediment loads for the water year 1955 are published in WSP 1402.

Rating tables, water year 1954-55 except Oct. 7-11, July 21, Sept. 26-28 (gage height,

Pecos River seepage investigation

During the water year 1954-55, several series of discharge measurements were made on 

the Pecos River and tributaries in New Mexico. The purpose was to determine seepage 

gains or losses. Three separate reaches of the Pecos River were measured, as described 

in the paragraphs below.

Two series of discharge measurements were made during the periods Dec. 14-16, 1954, 

and May 17, 18, 1955, on the Pecos River and tributaries, beginning at a point about 

8 miles below the Anton Chico, N. Mex., gaging station and ending about 4 miles below the 

Santa Rosa, N. Mex., gaging station, at the request of the Ground Water Branch to determine seepage gains or losses. The series of measurements Dec. 14-16 was made during 

a period of constant low flow; the series May 17, 18 was made during the spring runoff.

A double series of discharge measurements was made Jan. 5, 6, 1955, on the Pecos River 

and its tributaries beginning at the gaging station near Acme, N. Mex., and ending at the 

gaging station near Artesia, N. Mex., to determine seepage gains or losses. The investigation was conducted at a time of low and relatively stable flow and no diversions other 

than the Hagerman Canal were noted. One series was made starting at the upper end and 

working downstream and the other was made starting from the lower end and working upstream. Similar series of discharge measurements have been made in previous years and 

published under "Miscellaneous discharge measurements" in annual water-supply papers. 

Results of measurements are available on request to the district office in Sante Fe, 

N. Mex.

Several series of discharge measurements were made in February 1955 in the vicinity of 

Carlsbad, N. Mex., to determine gains or losses in the Pecos River. Two series were made 

at a time when Tansil Lake was empty to determine the inflow in the Carlsbad Springs area. 

The first, on Feb. 7, was made 21 days after the lake was drained, and the second, on 

Feb. 17, the day before the gates ih Tansil Dam were closed and the lake filled. A series 

of discharge measurements was made below Tansil Dam Feb. 21, 22, before the lake had 

filled and spill began. Harroun Canal was diverting all of flow of the Pecos River at 

that point, and can be considered as Pecos River discharge.

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

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

2 miles of canal headgate except as noted herein. Water diverted by these canals is 

used for irrigation of lands on both sides of Pecos River in Reeves, Ward, and Pecos 

Counties. Stations prior to 1941 were published separately (daily discharge figures for 

the earlier records).

RIO GRANDE BASIN 415

Comanche Springs at Fort Stockton, Tex.

Location. Lat 30°53', long 102°52', on left bank of outlet canal of Pecos County Water 

Improvement District No. 1, in eastern outskirts of Fort Stockton, Pecos County, 0.2 

mile upstream from bridge on U. S. Highway 290 and 0.5 mile downstream from head of 

springs.

Records available.--February 1941 to September 1955.

3.--W 

F929.

Gage.--Water-stage recorder. Datum of gage is 2,922.82 ft above mean sea level, datum of

Average discharge. 14 years, 34.5 cfs (24,980 acre-ft per year).

Extremes. 1941-55: Maximum daily discharge, that of June 4, 1955; minimum daily, that of 

June 26 to July 21, Aug. 3 to Sept. 30, 1955.

Remarks.--Records fair. Since about 1950, flow of springs greatly reduced at times by 

withdrawals from underground reservoir by irrigation wells. Beginning 1954 flow supplemented after rains by surface water released, directly and by underground leakage, 

from small flood-control reservoir located several hundred feet above springs. Water 

used to irrigate about 6,000 acres of land below station.

DISCHARGE MEASUREMENTS AT POINTS OTHER THAN GAGING STATIONS 429

Measurements of streamflow in the Western Gulf of Mexico basins made at points other 

than regular gaging stations are given in the following table. Most of these measurements 

were made during periods of base flow when streamflow is primarily from ground-water 

storage. Measurements believed to have been made under base-flow conditions are identified by an asterisk (*) to the left of the discharge figure. These measurements when 

correlated with the simultaneous discharge of a nearby stream where continuous records 

are available will give a picture of the low-flow potentiality of stream. The column 

headed "Measured previously" shows the water years in which measurements were made at 

the same, or practically the same, site.

Determinations of peak flow at points other than regular gaging stations are given in 

a separate table on page 433.
