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, 1951. Since 1888, when the United States Geological Survey first 

studied streamflow in relation to problems of irrigation, similar measurements have been 

made at more than 12,400 gaging stations in the 48 States and at many others in the Territories of Alaska and Hawaii. On September 30, 1951, the Geological Survey and cooperating 

organizations were maintaining 6,730 gaging stations, including those in Alaska and Hawaii. 

Miscellaneous discharge measurements were made at many other points in the 1951 water year.

COOPERATION

 teny State, municipal, and private organizations have cooperated with the Geological 

Survey in this work by either furnishing or helping to collect data. Organizations that 

supplied data are acknowledged in station descriptions, and organizations that assisted in 

the collection of data through cooperative agreements with the Survey are:

Texas: State Board of Water Engineers, consisting of H. A. Beckwith, chairman, A. 

P. Rollins, and J. S. Guleke; Red Bluff Water Power Control District; and Pecos River 

Commission, J. C. Wilson, commissioner.

Assistance in the form of funds or services was given by the Corps of Engineers, Department of the Army, in collecting records published herein for 83 gaging statior , of which 4 

were in Louisiana, 7 in New Mexico, and 72 in Texas.

Assistance was also furnished by the Office of Indian Affairs of the United States Department of the Interior in the operation of gaging stations on the Indian Pueblo lands in 

New Mexico, by the Pish and Wildlife Service, and the Bureau of Reclamation of the United

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.

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 stage-discharge 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.
EXPLANATION OF DATA 3

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 noneontributing areas, 

within the area unless otherwise noted.

NEW DOWNSTREAM ORDER OP LISTING GAGING STATIONS

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

order of listing gaging-station records has been 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 new 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

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 is used to supplement base data in determining the 

daily flow. The records of stage are obtained either from direct readings on a nonrecording gage or from a water-stage recorder that gives a continuous record of 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.

Rating tables giving the discharge for any stage are prepared from stage-discharge 

relation curves defined by discharge measurements. If extensions to the rating curves 

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

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

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

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

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 of stage is 

used as a factor in the determination of discharge.

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

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

the winter, 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 stream.

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 "Gage" are given the type of gage currently in 

use and the datum of the present gage above mean sea level, and a condensed history of the 

types of gages, locations, and datums of previous gages for which discharge records are 

generally equivalent to those at the present site. 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). 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 cr&st. 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."
6 SURFACE WATER SUPPLY, 1951, PART 8

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 report 

number, "W" means water-supply paper. 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 wh'ch 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.

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 daily mean gage 

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

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

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

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

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

discharge corresponding to 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 values for the maximum day and the minimum day for 

each month are underlined. If the value 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 values; 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"). Values for cubic feet per second per
ACCURACY OP FIELD DATA AND COMPUTED RESULTS 7

square mile and runoff, In Inches, are omitted If the drainage area Includes large noncontrlbutlng 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 values of maximum are the maximum 

dally discharges, not the momentary discharges when the water was at crest stage. Likewise, the mlnlmums In this summary are the minimum dally discharges.

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

most stations are listed below the table of dally 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 dally discharge Indicate periods when discharge was computed 

or estimated by unusual or sp^pial 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 dally 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 (1) the stability of the stagedischarge relation or, If the control Is unstable, the frequency of discharge measurements, 

and (2) the accuracy of observations of stage, measurements of 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 dally 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 dally 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, values 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.

255191 O - 53 - 2
SURFACE WATER SUPPLY, 1951, PART 8

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

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

Miscellaneous measurements at many points other than regular gaging stations have been 

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

of each report. The streams and points of measurement 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 Water-Supply Paper 119.

Each of the reports on the surface-water supply for the year 1939 (Water-Supply Paper 

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 Soil Conservation Service of the United States Department of Agriculture has been collecting 

records of runoff from 3 areas of less than 200 acres each near Waco, Tex., beginning in 1938. 

These records are in the files of the Soil Conservation Service.

HYDROLOGIC CONDITIONS

The water year 1951 was characterized by drought conditions over a large part of the 

Western Gulf of Mexico basins. At many gaging stations the annual discharge was the 

lowest during the period of record. There were no noteworthy floods In the area during 

the year. For two key stations in the area covered by this report, a comparison of 

monthly and annual mean discharges during the 1951 water year with the median discharge 

for the 25-year period 1921-45 Is shown In figure 3 on the following page.

Drainage area. 131 sq mi.

Records available. October 1938 to September 1951.

Gage. Water-stage recorder. Datum of gage is 14.84 ft above mean sea level, datum of 

T929 (Louisiana Geodetic Survey bench mark; levels by Corps of Engineers). Prior to 

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.--13 years, 267 cfs.

Extremes.--Maximum discharge during year, 2,210 cfs Feb. 2 (gage height, 16.10 ft); minimum, 0.1 cfs May 25, 26; minimum gage height, 0".90 ft May 26.

1938-51: Maximum discharge, 10,000 cfs July 7, 1946 (gage height, 21.15 ft); no 

flow May 7, 10-18, July 10, 1939, June 23-27, 30, July 1, 1948.

Remarks. Records good except those below 10 cfs and those for periods of no gage-height 

record or indefinite stage-discharge relation, which are fair. Station is above all 

known diversions for irrigation.

TTatum.

Extremes. 1949: Maximum discharge determined during period April to September, 820 cfs 

 Apr. i!2 (gage height, 11.51 ft), but may have been higher during period of no gage-, 

height record in July; minimum observed during period, 0.1 cfs May 13 (gage height, 

2.73 ft) but probably no flow occurred during period of no gage-height record in May 

and June.

1949-50: Maximum discharge during water year, 1,540 cfs Jan. 6 (gage height, 12.83 

ft); minimum, 0.1 cfs Nov. 25-28; minimum gage height, 2.72 ft Nov. 28.

ft, datum then in use, or about 23.5 ft, present datum), from rating curve extended 

above 40,000 cfs; maximum gage height, 24.7 ft Aug. 11, 1940 (discharge, 64,400 cfs); 

minimum discharge, that of Aug. 17, 1951.

Flood in 1913 reached a stage about 0.3 ft higher than that of Aug. 11, 1940.

Remarks . Records good. Paper mill at Elizabeth pumpa 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 the 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.

58 TRINITY RIVER BASIN

Clear Pork Trinity River at Port Worth, Tex.

Location. Lat 32°44', long. 97°21', near right bank on downstream side of right pier of 

orioge on Vickery Boulevard at Fort Forth, Tarrant County, 100 ft upstream from EastWest Expressway bridge, 310 ft (revised) downstream from Texas & Pacific Railway bridge, 

3 miles upstream from mouth, and 5 miles downstream from Marys Creek.

Drainage area. 526 sq mi.

Records available. March 1924 to September 1951.

Page. Water-stage recorder and concrete control. Datum of gage is 532.91 ft above mean 

sea level, datum of 1929. Prior to June 23, 1925, staff gage at site 338 ft upstream 

at datum 8.37 ft higher. June 23, 1925, to Dec. 7, 1938, water-stage recorder at site 

88 ft upstream at same datum.

Average discharge. 27 years, 116 cfs; median of yearly mean discharges, 82 cfs.

Extremes. Maximum discharge during year, 2,760 cfs June 3 (gage height, 5.93 ft); no flow 

ror many days.

1924-51: Maximum discharge, 107,000 cfs May 17, 1949 (gage height, 28.20 ft), from 

rating curve extended above 16,000 cfs on basis of contracted-opening determination of 

peak flow; no flow at times.

Maximum stage known since at least 1900, that of May 17, 1949. Flood of Apr. 25, 

1922, reached a stage of 27.5 ft, present datum (discharge, 74,300 cfs, by slope-area 

determination of peak flow, data by city engineer of Fort Worth).

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

Flood flow since August 1950 largely regulated by Benbrook Reservoir (capacity, 259,000 

acre-ft) located 10 miles upstream. During the year reservoir acted only as detention 

basin and no water was permanently stored. Texas & Pacific Railway Co. diverts small 

amount of water from pool in which gage is located. Records of chemical analyses and 

water temperatures for the water year 1951 are given in Water-Supply Paper 1199.

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 1951.

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

oT 1929, Galveston-Houston supplementary adjustment and Houston supplementary adjustment 

of 1943.

Extremes. Maximum gage height at dam during year, 78.7 ft Mar. 29, 30 (contents, 34 acre- 

 ft). Maximum at upper gage, 96.2 ft Mar. 28.

1945-51: 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, 98.1 

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 five concrete conduits, 

two of which are uncontrolled. The middle conduit is controlled by two vertical-lift 

steel gates; the two 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 flood pool). No constructed emergency spillways; runoff considerably 

in excess of designed capacity will be discharged around ends of dam. Gage heights and 

contents not published for floods that do not produce a gage height of 82.0 ft (top of 

outlet structure) or higher at dam.

of 1929, Houston supplementary adjustment of 1943. Prior to Nov. 26, 1949, staff gage 

at site 40 ft downstream at same datum.

Extremes. Maximum discharge during year, 936 cfs Sept. 14 (gage height, 12.66 ft); no 

now at times.

1944, 1946, 1947: Maximum discharge not determined; minimum observed, 1.0 cfs 

Oct. 31, 1944.

1948-51: Maximum discharge, 7,400 cfs Oct. 8, 1949 (gage height, 18.80 ft, from 

floodmark), from rating curve extended above 4,000 cfs by logarithmic plotting; no 

flow at times in 1950.

Maximum stage known in recent years, 19.9 ft July 14, 1939, present site and datum 

(adjusted from floodmark 2,600 ft to right and 250 ft downstream from gage, on basis 

of slope of flood of Oct. 8, 1949), from information by local residents.

120 BRAZOS RIVER BASIN

Brazos River at Waco, Tex.

Location. Lat 31°33'40", long. 97°07'45", on right bank at downstream side of pier of 

Washington Avenue Bridge in Waco, McLennan County, 2| miles downstream from Bosque 

River and at mile 404.

Drainage area.--28,500 sq mi, approximately, of which 9,240 sq mi is probably noncontriouting.

Records available.--September 1898 to September 1951 (January 1912 to September 1914, 

monthly records only, in Water-Supply Paper 850). Gage-height records collected in 

this vicinity since 1900 are contained in reports of United States Weather Bureau.

Gage. Water-stage recorder. Datum of gage is 356.80 ft above mean sea level, datum of

 T929, supplementary adjustment of 1942. Sept. 14, 1898, to Mar. 28, 1918, May 6, 1922, 

to Feb. 12, 1934, staff or chain gages at several sites within about 350 ft of present 

site and at same datum. Mar. 28, 1918, to May 5, 1922, Feb. 13, 1925, to Sept. 29, 1934, 

water-stage recorder at site about 300 ft downstream at same datum.

Average discharge. 53 years, 2,632 cfs.

Extremes. Maximum discharge during year, 18,300 cfs June 13 (gage height, 15.88 ft); mini-

 mum, 102 cfs Apr. 12.

1898-1951: Maximum discharge, 246,000 cfs Sept. 27, 1936 (gage height, 40.90 ft, 

levee on left bank was overtopped and broken by flood); minimum discharge for periods 

of daily record, 1898-1911, 1914-51, no flow Aug. 20, 21, 1918, and probably for several 

days in August 1923.

Maximum stage, 1854-97, 34.2 ft May 28, 1885. A stage of 39.7 was reached Dec. 3, 

1913, when levee on left bank was broken by flood, from information by United States 

Weather Bureau.

Remarks. Records good. Flow largely regulated by Possum Kingdom Reservoir on Brazos 

River (see p.112), and several small reservoirs in Clear Fork Basin, and Lake Waco on 

Bosque River near Waco (capacity, 22,000 acre-ft). A siltation survey of Lake Waco by 

the Soil Conservation Service of the United States Department of Agriculture in December 1947 indicates a 44.07 percent capacity loss from siltation since storage began in 

April 1930. Many small diversions above station for municipal supply, irrigation, and 

oil-field operation do not appreciably affect flow.

Revisions (water years).--W 850 and W 878: (monthly and yearly summaries only, 1899-1905, 

1907-10).

122 BRAZOS RIVER BASIN

Leon River seepage investigation

A series of discharge measurements was made Mar. 13, 14, 1951, on the Leon River and 

its tributaries, from a point 3.7 miles southeast of Eastland, Tex., to the gaging station near Hasse, Tex., to determine seepage gains or losses between those points, a

138 BRAZOS RIVER BASIN

Brazos River near Juliff, Tex.

Location --Lat 29°26, long. 95°32', on left bank just downstream from South Texas Water

 Co', pumping plant, 3| miles west of Juliff, Fort Bend County, 5? miles downstream from 

Gulf, Colorado & Santa Fe Railway bridge, and at mile 67.

Drainage area. 44,130 sq mi, approximately, of which 9,240 sq mi is probably noncontributing.

Records available. May 1949 to September 1951.

Gage.--Two water-stage recorders. Datum of gage is at mean sea level, datum of 1929,

 Eouston supplementary adjustment of 1943.

Extremes. Maximum discharge during year, 10,300 cfs June 17 (gage height, 28.20 ft); no

 now at times due to pumping.

1949-51: Maximum discharge, 48,500 cfs Feb. 15, 1950; maximum gage height, 43.26 

ft Feb. 16, 1950; 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 

of July 1899 was probably exceeded only by flood of 1913.

Remarks.--Records good. Flow largely regulated by reservoirs above Waco. Considerable

 waTer diverted above station for irrigation and municipal supply. See records of 

American Canal Co.'s canal near Fulshear (p.135) and Richmond Irrigation Co.'s canal 

near Richmond (p.136). 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.

Remarks . Reservoir is formed by a rolled-fill earthen dam, 4,800 ft long; storage began 

in April 1949; dam completed in September 1949. Reservoir is operated by Texas Electric Service Co. for cooling purposes in operation of steam power plant. Colorado City 

diverts water for municipal supply (see table below).

Service spillway is of cloverleaf design, located 100 ft upstream from dam, having 

two uncontrolled openings 10 by 12 ft, designed to discharge a total of 5,000 cfs. An 

emergency spillway, 1,200 ft wide and designed to discharge 150,000 cfs directly into 

the Colorado River, is located 600 ft upstream and to left of dam. Capacity of reservoir, 37,700 acre-ft at elevation 2,073.7 ft (top of emergency spillway), 30,800 acreft at elevation 2,070.3 ft (top of service spillway), and 200 acre-ft dead storage at 

elevation 2,024.3 ft (bottom of service outlet conduit). Water for municipal supply 

can be withdrawn down to elevation 2,045 ft. Capacity curve prepared and furnished by 

Preese & Michols, consulting engineers.

gage heights -4.0 ft (bottom of two 36-in. gates) and 32.4 ft (top of collapsible 

flood gate). Figures of contents shown herein represent total contents of lake, and 

are unadjusted for siltation. A siltation survey made by the United States Department 

of Agriculture, Soil Conservation Service, indicates a 10 percent capacity loss from 

siltation in 8.2 years (1930-39). Water used for San Angelo municipal supply.

South Concho River at San Angelo, Tex.

Location. Lat 31°26'45", long. 100°25'30", near right bank on downstream side of pier of 

 Lone "Wolf Bridge on county road, 0.5 mile south of San Angelo, Tom Green County, 1 mile

upstream from confluence with North Concho River, and 7,470 ft downstream from bridge

on U. S. Highways 87 and 277.

Drainage area.--2,687 sq mi, of which 152 sq mi is probably noncontributing. 

Records available. October 1931 to September 1951.

Gage.--Water-stage recorder above San Angelo waterworks concrete dam. Datum of gage is 

T,802.94 ft above mean sea level, datum of 1929.

Average discharge. 20 years, 122 cfs.

Extremes. Maximum discharge during year, 92 cfs Aug. 12 (gage height, 2.43 ft); no flow

1931-51: Maximum discharge, 111,000 cfs Sept. 17, 1936 (gage height, 23.4 ft, of 

which about 2.4 ft was caused by backwater from North Concho River), by slope-area 

method; no flow at times.

Maximum stage known since at least 1854, 29.7 ft Aug. 6, 1906 (not affected by backwater), from information by local residents.

Remarks.--Records good except those for Dec. 23 to Jan. 28, which are poor. Diversions 

above station for irrigation and fish hatcheries. The city of San Angelo diverted 9,910 

acre-ft just above control for municipal use during current water year. Flow largely 

regulated by Lake Nasworthy (see preceding page).

cfs Feb. 26, 1918.

Remarks. Discharge mt-asurements 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 Edwards 

Plateau. Water used for recreational purposes.

GUADALUPE RIVER BASIN 199

San Antonio River at San Antonio, Tex.

Location. Lat 29°24'35", 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, 

age area of stream not applicable.

Normal flow of river comes from springs; drainRecords available. January 1915 to November 1929, February 1939 to September 1951. Estimated monthly ground-water discharge contained in Water-Supply Paper 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. Apr. 8, 1920, to Nov. 16, 1929, water-stage recorder at same site 

and datum.

Average discharge. 26 years (1915-29, 1939-51), 66.3 cfs.

Extremes. Maximum discharge during year, 1,800 cfs June 3 (gage height, 8.22 ft); minimum, 2.1 cfs Jan. 4; minimum daily, 12 cfs Jan. 4.

1915-29, 1939-51: 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 parts of occasional days.

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, 

It),500 acre-ft) about 8^ 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.

 "near (Jotulla" 1915-18. Gage-height records collected in this vicinity, 1914-17 and 

since 1922, are contained in reports of United States Weather Bureau.

Gage. Wire-weight gage read once daily. Datum of gage is 368.08 ft above mean sea level,

 3atum of 1929. July 1, 1915, to June 13, 1918, staff gage at Hargus Dam, 4 miles upstream at different datum; Oct. 31, 1923, to Aug. 3, 1924, staff gage at approximate 

site of present gage at datum 7.28 ft higher; Aug. 4, 1924, to Nov. 19, 1934, staff gage 

at site 5,000 ft downstream at datum 8.42 ft higher; Nov. 20, 1934, to July 15, 1938, 

water-stage recorder at present site and datum.

Average discharge.--28 years (1923-51), 297 cfs.

Extremes. Maximum discharge during year not determined; maximum gage height observed,

 ly.b'U ft May 30; no flow at times.

1923-51: Maximum discharge, 82,600 cfs June 18, 1935 (gage height, 32.4 ft, from 

floodmarks), from rating curve extended above 41,000 cfs on basis of slope-area determination of peak flow; no flow at times.

Maximum stage known since at least 1899, that of June 18, 1935. Flood of June 19, 

1899, reached a stage of 29.7 ft, from information by local residents.

Remarks.--Records poor. Part of flow of Nueces River and its headwater tributaries enters

 .Edwards limestone in Balcones fault zone which crosses basin Just north of Uvalde. At 

low stages most of headwater flow enters this formation. Low flow slightly regulated 

by small storage reservoirs above station; most of it is diverted above station by 

pumping.

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

218 NUECES RIVER BASIN

Atascosa River at Whitsett, Tex.

Location.--Lat 28 0 37'20", long 980 17'05", on right bank 1,600 ft upstream from bridge on

 Whitsett-Calliham county road, 0.9 mile west of Whitsett, Live Oak County, and 4 miles 

downstream from La Parita Creek.

Drainage area. 1,171 sq mi.

Records available.--September 1924 to May 1926, May 1932 to September 1951.

Gage. Water-stage recorder and artificial control. Datum of gage is 159.04 ft above

 mean sea level, datum of 1929. Prior to May 8, 1926, chain gage at bridge 1,600 ft

downstream at datum 1 38 ft higher.

Average discharge.--20 years (1924-25, 1932-51), 144 cfs.

Extremes. Maximum discharge during year, 6,060 cfs Sept. 14 (gage height, 25.49 ft); min-

 linum, 0.2 cfs Nov. 4, July 30 to Aug. 6.

1924-26, 1932-51: Maximum discharge, 39,300 cfs July 7, 1942 (gage height, 38.3 ft, 

from floodmark), from rating curve extended above 12,000 cfs on basis of slope-area 

determination at gage height 38.0 ft; no flow at times.

Maximum stage known, that of July 7, 1942.

Remarks.--Records good. A considerable part of the flow during the period June 25 to

 Sept. 10 resulted from the flow of several artesian wells near Campbellton, which were 

drilled by the Lower Nueces River Water Supply District and turned into the river to 

supplement the supply for the city of Corpus Christ!. See unpublished report, "Investigations of Seepage Gains and Losses in Atascosa, Frio, and Nueces Rivers from Poteet, 

Tex-. to Mikeska, Tex. during January, April, August, and September 1951, on file in 

Washington, D. C. and Austin, Tex. offices of Geological Survey.

NUECES RIVER BASIN 219

Nueces River near Three Rivers, Tex.

Location. Lat 28°26'10", long. gSTL'lO". on left bank 100 ft downstream from San An-

 tonio, Uvalde & Gulf (Missouri Pacific) Railroad bridge, half a mile downstream from 

Prio River, and 2 miles south of Three Rivers, Live Oak County.

Drainage area. 15,600 sq ml.

Records available. July 1915 to September 1951. United States Weather Bureau has collect' 

ed gage-height record* in this vicinity since 1922.

Gage. Water-stage recorder and concrete control. Datum of gage is 101.16 ft above mean

 sea level, datum of 1929. Prior to Apr. 5, 1932, staff gage at railroad bridge 100 ft 

upstream at same datum.

Average discharge. 34 years (1915-18, 1920-51), 811 cfs.

Extremes. Maximum discharge during year, 18,800 cfs Sept. 15 (gage height, 37.20 ft); no 

now at times.

1915-51: 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 good. Part of flow of Nueces and Frio Rivers and their headwater trib-

 utaries 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 chemical analyses, water temperatures, and 

sediment loads for the water year 1951 are given in Water-Supply Paper 1199.

Revisions (water years). W 548: 1920, 1921.

220 NUECES RIVER BASIN

Lake Corpus Christ! near Mathis, Tex.

Location. Lat 28°03', long. 97°52', near left end of Lake Corpus Christ! Dam on Nueces 

Kiver, three-quarters of a mile upstream from bridge on U. S. Highway 96 and 4 miles 

southwest of Mathis, San Patrlclo County.

Drainage area. 16,656 sq ml.

Records available. September 1948 to September 1951. The Soil Conservation Service,

United states 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.

Gage. Wire-weight gage read once dally. Datum of gage Is 0.52 ft above mean sea level, 

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

first buttress wall of left talntor gate was probably used.

Extremes. Maximum contents observed during year, 52,920 acre-ft Sept. 17, 18 (gage 

 height, 76.45 ft); minimum observed, 14,740 acre-ft May 5 (gage height, 67.10 ft).

1948-51: Maximum contents observed, 57,000 acre-ft Apr. 30, 1949 (gage height, 77.05 

ft); minimum observed, that of May 5, 1951-.

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

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

complete and storage began July 24, 1934. Capacity, 39,400 acre-ft at gage height 74 

ft (top of talntor 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, United States Department of 

Agriculture, found original capacity of the reservoir to have been 54,000 acre-ft, and 

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

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

Coop aration. Capacity curve furnished by the" Soil Conservation Service, United States 

apartment of Agriculture. Gage-height record furnished by city of Corpus Christ!.

Principal diversions from Costilla Creek, N. Mex. and Colo.

Records of discharge are collected at nine gaging stations on four diversions from 

Costilla Creek. Each of these stations is equipped with a water-stage recorder and a 

Parshall flume. Water diverted is used for irrigation in the Sangre de Cristo Grant,in 

New Mexico and Colorado below the gaging station near Costilla. Records are collected 

during irrigation seasons only. Discharge measurements generally made twice a month 

except during winter period.

fo Oct. 4, 1933, at railroad bridge 2 miles downstream at different datum. Oct. 4, 

1933, to Mar. 1, 1942, at site 150 ft upstream at datum 0.22 ft higher.

Average discharge.--37 years (1913-17, 1918-51), 646 cfs.

Extremes. Maximum discharge during year, 1,410 cfs Feb. 11 (gage height, 3.51 ft); no flow 

Aug. 19, Sept. 16-18, 25.

1930-51: Maximum discharge, 9,910 cfs May 14, 1941; maximum gage height, 8.33 ft, 

present datum, May 16, 1941; no flow at times.

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

which are poor. Discharge measurements generally made twice a month. Diversions above 

station for irrigation of about 30,000 acres, a few hundred of which are below station. 

Flow regulated by El Vado Reservoir (see p. 370 ). Records of sediment loads for the 

water year 1951 are given in Water-Supply Paper 1199.

Rio Grande near Bernardo, N. Mex.

Location.--Lat 34°25'00", long. 106°47'50", in wiNW^ sec. 12, T. 2 N., R. 1 E. (projectedi

 at bridge on U. S. Highway 60, 2£ miles east of Bernardo and 3^ miles upstream from Rio 

Puerco.

Drainage area. 19,230 sq mi, approximately (includes 2,940 sq mi in closed basin in 

nortnern part of San Luis Valley, Colo.).

Records available. June 1936 to January 1939, October 1941 to September 1951.

Gage. Water-stage recorder. Datum of gage is 4,723.95 ft above mean sea level, datum of

 T929. Supplementary recording gages at different datums on San Francisco riverside 

drain and Bernardo interior drain used when these channels carry river water.

Average discharge. 11 years (1936-38, 1941-42, 1943-51), 1,351 cfs.

Extremes.--Maximum daily discharge during year, 1,630 cfs Feb. 15; no flow at times.

 1336-39, 1941-51: Maximum discharge not determined, probably occurred Apr. 25, 

1942; maximum daily discharge, 19,600 cfs Apr. 25, 1942; maximum gage height, 6.90 ft 

Apr. 25, 1942; no flow at times in 1951.

Remarks. Records good above 300 cfs and fair below except those for periods of no gage-

 neignt record, which are poor. Records represent total discharge of river and are a 

summation of the discharge in the channels that carry river water. Except for Aug. 22, 

the entire river discharge for this year passed through the San Francisco riverside 

drain. Discharge measurements generally made once or twice a week. Diversions for 

irrigation of about 740,000 acres above station. Records of sediment loads for the 

water year 1951 are given in Water-Supply Paper 1199.

Discharge, In cubic feet per second, water year October 1950 to September 1951

Location (revised).--Lat 35°35 T 40", long. 107°11'20", in NE^ sec. 30, T. 16 N., R. 3 W., 

a quarter or a mile upstream from mouth, 4? miles northwest of Guadalupe, and 5? miles 

southwest of Cabezon.

Drainage area. 1,390 sq mi, approximately.

Records available. November 1943 to September 1951.

Gage.--Water-stage recorder and concrete control. Altitude of gage is 5,895 ft.

Average discharge.--8 years (1943-51), 17.8 cfs.

Extremes. Maximum discharge during year, 11,100 cfs July 31 (gage height, 14.0 ft), from 

rating curve extended above 2,800 cfs on basis of slope-area determinations at gage 

heights 9.6 and 12.8 ft; no flow at times.

1943-51: Maximum discharge, 12,700 cfs July 21, 1944, from rating curve extended 

above 2,500 cfs by logarithmic plotting; maximum gage height, that of July 31, 1951; 

no flow at times.

Remarks. Records fair above 10 cfs, poor below. Discharge measurements generally made 

three times a month, but more frequently during periods of high flow. Diversions for 

irrigation of about 100 acres above station. Records of water temperatures and sediment loads for the water year 1951 are given in Water-Supply Paper 1199.

Location. Lat 34°58'00", long. 107°10'10", in NE£ sec. 32, T. 9 N. , R. 3 W., on left bank 

u.t> mile upstream from U. S. Highway 66, 0.7 mile northeast of Correo, and 13 miles upstream from mouth.

Drainage area. 2,610 sq mi, approximately. 

Records available. April 1943 to September 1951.

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

sea level, unadjusted.

Average discharge. 8 years, 8.24 cfs.

Extremes, Maximum discharge during year, 988 cfs Aug. 25 (gage height, 3.50 ft); no flow 

iL or much of year.

1943-51: Maximum discharge, 8,010 cfs May 26, 1944 (gage height, 9.20 ft), from 

rating curve extended above 1,700 cfs by logarithmic plotting; no flow for long periods.

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

during the flood of August 1929.

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

Discharge measurements generally made three times a month. Plow 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 sediment loads for the water 

year 1951 are given in Water-Supply Paper 1199.

Rating table, water year 195O-51, except periods of no gage-height record (gage

height, in feet, and discharge, in cubic feet per second)

(Shifting-control method used Aug. 29 to Sept. 9)

 center of span on downstream side of bridge on U. S. Highway 70, at Hondo, half a mile 

upstream from confluence with Rio Ruidoso.

Drainage area. 306 sq mi (contributing area). 

Records available. October 1930 to September 1951.

Gage.--Water-stage recorder and concrete control. Altitude of gage is 5,109 ft (from

 TJtate topographic map). Prior to Feb. 4, 1933, at site a quarter of a mile upstream 

at different datum. October 10, 1931, datum lowered 0.23 ft.

Average discharge. 21 years, 11.4 cfs.

Extremes.--Maximum discharge during year, 2,130 cfs July 31 (gage height, 7.90 ft); no

 flow at times.

1930-51: Maximum discharge, 11,000 cfs Sept. 28 or 29, 1941 (gage height, 20.92 ft, 

from floodmark), from rating curve extended above 220 cfs on basis of slope-area determination at gage height 19.0 ft; no flow at times.

Revisions. The maximum discharge and gage height for water year 1950 have been revised to 4.S30 cfs July 6 (gage height, 13.66 ft), superseding figures published in 

Water-Supply Paper 1178.

Remarks. Records good except those for periods of ice effect and those above 100 cfs,

 which are poor. Low flow regulated by Bonito reservoir. Diversions for irrigation of 

about 1,700 acres above station.

Revisions.--Revised figures of discharge for the water year 1950, superseding those pub-

 lished in Water-Supply Paper 1178, are given herein.

Rating tables, Oct. 1, 1949, to Sept. 30, 1951, except period of Ice effect (gage

height, In feet, and discharge, In cubic feet per second)

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

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

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

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

2 miles of canal head gate except as noted herein. Water diverted by these canals is used 

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

Stations prior to 1941 were published separately (daily discharge figures for the earlier 

records).
