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, 1957. 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 13,750 gaging stations in the 48 States and at many others in 

the Territories of Alaska and Hawaii. On September 30, 1957, the Geological Survey and 

cooperating organizations were maintaining 7,030 gaging stations, including those in 

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

1957 water year. 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.

stations given in this report is on file in the district offices listed above. Provisional records of discharge prior to publication and other unpublished data concerning 

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 noncontributing areas, 

within the area unless otherwise noted.

WSP is used as an abbreviation 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 gaging-station 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

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 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 Wster-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 OF 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 basis 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 discharga and monthly and yearly discharge and 

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

and ends on September 30. A calendar of the water year 1957 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 and 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 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
6 SURFACE WATER SUPPLY, 1957, PART 8

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.

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
EXPLANATION OP DATA 7

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 published each year for all reservoirs for which records are published on 

a daily basis, but is not published for reservoirs for which only monthly data are given.

Discharge measurements and determinations of peak flows made at sites other than gaging

stations are listed at the end of each report.

At many gaging stations water samples are collected from the streams for the purpose

of making chemical analyses, computing dissolved solids, suspended sediment loads, and 

particle-size distribution, or measuring water temperatures. For most of these samples 

the results are published in an annual series of water-supply papers entitled "Quality 

of Surface Waters of the United States" which is issu*ed in four volumes. In this report

S03666 O - 59 * Z
8 SURFACE WATER SUPPLY, 1957, PART 8

under "Remarks" a reference is made to quality-of-water records collected at gaging stations on a regular basis and published in the quality-of-water reports. At many other 

gaging stations quality-of-water data are obtained at irregular intervals and published as 

"miscellaneous analyses" in quality-of-water reports; such records are not referred to in 

"Remarks" paragraph in this report. At many gaging stations water temperature is obtained 

also at the time a discharge measurement is made; such temperature readings are not reported in the quality-of-water annual reports.

ACCURACY OP 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 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 

for each of the 14 parts. Beginning with the reports for 1951, the records are published 

in 18 volumes, there being 2 volumes each for Parts 1, 2, 3, and 6. The boundaries of the 

various parts are indicated by the following list and the map in figure 2.

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.

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 on 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 130 to 310 acres, beginning In 1937, from 

4 areas of 3 to 1,110 acres, beginning In 1938, from 8 areas of 3 to 140 acres beginning In 1939 

(most of these records Incomplete from 1943 to about 1949); near Albuquerque, N. Mex., from 3 areas 

of 40 to 190 acres, beginning In 1939, and near Santa Rosa, N. Mex., from 1 area of 42,900 acres 

beginning In 1955.

HYDROLOGIC CONDITIONS ^

During the first six months of the 1957 water year, streamflow was deficient throughout 

the area covered by this report, with the exception of a small area in central Texas. 

This condition was a continuation of the drought that began in New Mexico about 1943 and 

spread across Texas by 1950. Monthly mean discharge was record-low at one or more longterm gaging stations in New Mexico and Texas every month from October to February.

In March flow increased in scattered areas, and in April floods occurred in east and 

central Texas, filling most reservoirs. Floods continued through May, with excessive 

streamflow throughout all of Texas except the extreme western part. The peak discharge 

of Sulphur Creek near Lampasas on May 12 was the highest since 1873, when the maximum 

known flood occurred. Although few peak flows were record-breaking, the floods of April 

to June in Texas were outstanding because of the very large area covered, the duration of 

high flow, and the large volume of runoff produced, ending the prolonged drought. A 

detailed report of these floods will be published as a chapter of WSP 1580.

Heavy runoff occurred in eastern Texas in August as a result of tropical hurricanes. 

Streamflow was excessive in most parts of New Mexico in August, due to almost daily rains, 

which were heavy in some localities. Moderate flooding occurred in some parts of Texas 

Sept. 22-27.

For three representative long-term gaging stations in the area covered by this report, 

a comparison of monthly and yearly mean discharges during the 1957 water year with the 

median discharges for the 25-year period 1921-45 is shown in figure 3 on the following

CALCASIEU RIVER BASIN

Calcasieu River near Oberlin, La.

Location. Lat 30°38'25", long 92°48'50", in NW^NE^ sec. 7, T. 5 S. , R. 4 W. , near right 

bank on downstream side of bridge on State Highway 26, 3 miles northwest of Oberlin and 

15 miles upstream from Whiskey Chitto Creek.

Drainage area. 753 sq mi.

Records available. August 1922 to January 1925, September 1938 to September 1957.

Gage.--Water-stage recorder. Datum of gage is 39.43 ft above mean sea level, datum of 

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

recorder at same site at datum about 2^ ft higher. September 1938 to Aug. 17, 1939, 

wire-weight gage at same site and datum.

Average discharge.--21 years (1922-24, 1938-57), 1,238 cfs (896,300 acre-ft per year).

Extremes. Maximum discharge during year, 6,870 cfs Dec. 25 (gage height, 15.96 ft); minimum, 30 cfs Oct. 17-19 (gage height, 2.72 ft).

1922-25, 1938-57: Maximum discharge, 72,800 cfs May 19, 1953 (gage height, 26.53 

ft); minimum, 30 cfs Sept. 28, 29, Oct. 17-19, 1956; minimum gage height, that of 

Oct. 17-19, 1956.

Flood in June 1886 reached a stage of between 22 and ?3 ft, present datum. 

Revisions.--Figures of maximum discharge for the water years 1923 and 1939 have been 

revised to 30,300 cfs Apr. 7, 1923 (gage height, 18.48 ft, datum then in use, or about 

21 ft, present datum) and 10,900 cfs Jan. 18, 1939 (gage height, 17.60 ft), superseding 

figures published in WSP 568 and 878, respectively.

Remarks. Records good. Paper mill at Elizabeth pumps about 11 cfs from wells which is 

later discharged into Mill Creek 20 miles above station. This discharge is continuous 

and fairly constant.

Revisions. Revised figures of discharge, in cubic feet per second, for the water year 

1923, superseding those published in WSP 568, are given herewith:

CA1CASIEU RIVER BASIN 31

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 

Whisky 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 1957 (discontinued).

f

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

929 (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 . 21 years (1922-24, 1938-57), 2,778 cfs (2,011,000 acre-ft per year).

Extremes. Maximum discharge during year, 24,300 cfs Dec. 25 (gage height, 18.52 ft); min- 

 ImumT 220 cfs Oct. 18-20 (gage height, 2.15 ft).

1922-25, 1938-57: Maximum discharge, 182,000 cfs May 19, 1953'(gage height, 32.00

ft); minimum, 136 cfs (regulated) Aug. 15, 1956; minimum gage height, 1.99 ft Aug. 17,

1951.

Remarks. Records good. Paper mill at Elizabeth pumps about 11 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.

West Pork Trinity River near Boyd, Tex.

Location. Lat 33°05'05", long 97°33'30", on right bank at downstream side of bridge on 

State Farm Road 730, 0.6 mile northeast of Boyd, Wise County, 3.5 miles downstream from 

Boggy Creek, and at mile 602.

Drainage area. 1,729 sq mi.

Records available. January 1947 to September 1957.

Gage. Water-stage recorder. Datum of gage is 660.57 ft above mean sea level, datum of 

1929. Prior to Dec. 14, 1954, at site 2.2 miles downstream at datum 5.48 ft lower.

Average discharge. 10 years, 230 cfs (166,500 acre-ft per year).

Extremes. Maximum discharge during year, 24,400 cfs Apr. 27 (gage height, 21.60 ft); no 

flow at times.

1947-57: Maximum discharge, that of Apr. 27, 1957; no flow at times.

Flood in April 1942 reached a stage of 20.6 ft, from information by State Highway 

Department. Flood in 1908 was highest since at least 1880 and reached a stage of about 

25 ft, from information by local residents.

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

Flow largely regulated by Bridgeport Reservoir since 1932 and Amon Carter Reservoir 

near Bowie, since May 1956, combined capacity, 292,000 acre-ft. Sustained flow during 

several periods is release from Bridgeport Reservoir, 21 miles upstream.

TRINITY RIVER BASIN 85

Eagle Mountain Reservoir above Port Worth, Tex.

Location. Lat 32°52>35", long 97°28'15", at right end of main dam on West Pork Trinity 

River, 3.0 miles downstream from Ash Creek, 4.1 miles downstream from Walnut Creek, 

14.6 miles northwest of Fort Worth, Tarrant County, and at mile 583.

Drainage area. 1,974 sq mi.

Records available.--February 1934 to September 1957 (prior to October 1950, monthly figures 

only).

Gage. Staff gage read once daily at 8 a.m. Datum of gage is at mean sea level, datum of 

T929. Prior to Feb. 24, 1943, staff gages at several sites within 1 mile of present 

site at present datum.

Extremes. Maximum contents observed during year, 292.200 acre-ft May 27 (elevation, 658.9 

ft); minimum observed, 57,690 acre-ft Nov. 19, 20 (elevation, 629.3 ft).

1934-57: Maximum contents observed, 333,500 acre-ft Apr. 26, 1942 (elevation, 659.9 

ft); minimum observed at monthly intervals since appreciable storage began, 9,320 acreft June 30, 1934.

Remarks.--Reservoir is formed by composite rolled-fill and hydraulic-fill earthen-type dam, 

containing a concrete service spillway with four 25-foot bays, three of which are 

equipped with vertical lift gates, and the other left open. There is an emergency 

spillway of natural ground. Dam completed Oct. 24, 1932, and storage began Feb. 28, 

1934. Dead storage is negligible. Reservoir used for flood control and to maintain 

level of Lake Worth from which city of Fort Worth derives its municipal supply. Figures 

given herein represent total contents. Capacity figures since Oct. 1, 1951, are based 

on redetermination of reservoir capacity during fall of 1952. Various features of dam

86 TRINITY RIVER BASIN

Clear Fork Trinity River near Aledo, Tex.

Location. Lat 32"38'25", long 97"33'50", on left bank 3 miles downstream from Turkey 

Creek, 3| miles upstream from bridge on U. S. Highway 377, 4 miles southeast of Aledo, 

Parker County, and 11.8 miles upstream from Benbrook Dam.

Drainage area. 246 sq mi.

Records available. August 1947 to September 1957.

Gage. Water-stage recorder. Datum of gage is 723.33 ft above mean sea level, datum of 

1929 (Corps of Engineers benchmark).

Average discharge. 10 years, 43.3 cfs (31,350 acre-ft per year).

Extremes. Maximum discharge during year, 34,000 cfs May 25 (gage height, 29.00 ft); no 

flow at times.

1947-57: Maximum discharge, that of May 25, 1957; no flow at times. 

Maximum stage known since 1858, about 34 ft between Apr. 25 and May 9, 1922, from 

information by local resident.

Remarks.--Records good. At the end of the year the flow from 68.8 sq mi above this station 

was partly controlled by 27 floodwater detention reservoirs with a total combined capacity of 22,620 acre-ft below the flood spillway crests, of which 19,260 acre-ft is floodwater detention capacity and 3,360 acre-ft is sediment storage capacity. Six of these 

reservoirs were constructed during the current year and have a total combined capacity 

below flood spillway crests of 6,179 acre-ft, of which 812 acre-ft is sediment pool 

capacity. The capacity in these reservoirs allocated to sediment storage will be used 

for conservation storage until eliminated by sedimentation. The Weatherford City Reservoir modifies runoff from 105 sq mi above the gaging station. The reservoir has a 

capacity of 19,470 acre-ft at elevation 896.0 ft (fixed glory hole outlet) and 35,180 

acre-ft at elevation 906.0 ft (emergency flood spillway).

flow Oct. 1-5.

1920-57: Maximum discharge, 85,000 cfs Apr. 25, 1922 (gage height, 23.95 ft, site 

then in use), by slope-area determination of peak flow by city engineer of Fort Worth; 

maximum gage height, 25.91 ft (site then in use) May 17, 1949 (discharge, 64,300 cfs); 

no flow at times.

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

been affected by levee construction, levee breaks, and channel rectification.

Remarks. Records good. Flow largely regulated by Bridgeport Reservoir since 1932 (see 

p. 82), Eagle Mountain Reservoir since 1934 (see p. 85), Benbrook Reservoir since 1952 

(see p. 87), and Lake Worth (capacity, 33,300 acre-ft). During year city of Fort 

Worth diverted 50,500 acre-ft of water from Lake Worth for municipal use and returned 

31,500 acre-ft of sewage effluent below station. Several small diversions above 

station.

92 TRINITY RIVER BASIN

Elm Fork Trinity River near Muenster, Tex.

Location. Lat 33 0 37', long 97°23', on left bank 80 ft upstream from bridge on Farm Road 

373, 2.5 miles south of Muenster, Cooke County, 2.5 miles downstream from Long Branch, 

and 6.5 miles upstream from Brushy Elm Creek.

Drainage area. 46.0 sq mi, of which 30.97 sq mi Is above flood-detention structures. 

Records available. October 1956 to September 1957.

Gage.--Water-stage recorder. Datum of gage is 890.33 ft above mean sea level, datum of 

1929 (Soil Conservation Service benchmark).

Extremes. Maximum discharge during year, 3,480 cfs Apr. 26 (gage height, 15.20 ft), from 

rating curve extended above 1,300 cfs; no flow at times.

Maximum stage known since at least 1900, about 23 ft in May 1935, from Information 

by local resident.

Remarks. Records good except for those above 1,500 and below 100 cfs, which are fair, and 

those for period of no gage-height record, which are poor. The flow from 30.97 sq mi 

above this station was partly controlled by 11 floodwater-detention reservoirs with a 

total combined capacity of 11,315 acre-ft below spillway crests, of which 9,834 acreft is floodwater detention capacity and 1,481 acre-ft is sediment storage capacity. 

The capacity in these reservoirs allocated to sediment storage will be used for conservation storage until eliminated by sedimentation. Station operated as part of Elm 

Fork Trinity River basin hydrologic cooperative program to evaluate rainfall-runoff 

relation, soil conservation practices, and the effects of flood-detention structures.

TRINITY RIVER BASIN 93

Elm Fork Trinity River near Sanger, Tex.

Location. Lat 33°23'25", long 97°05'10", on right bank on downstream side of pier of 

bridge on State Farm Highway 455, 4.1 miles downstream from Spring Creek, 5.0 miles 

upstream from Isle du Bois Creek, and 5.4 miles northeast of Sanger, Denton County.

Drainage area. 379 sq mi.

Records available.--April 1949 to September 1957.

Gage. Water-stage recorder. Datum of gage is 553.93 ft above mean sea level, datum of 

1929, Port Worth supplementary adjustment of 1942 (Corps of Engineers benchmark). 

Prior to May 7, 1955, at site 500 ft downstream at same datum.

Average discharge . 8 years, 128 cfs (92,670 acre-ft per year).

Extremes.--Maximum discharge during year, 20,800 cfs Apr. 26 (gage height, 27.45 ft); minimum, 2.8 cfs Jan. 19.

1949-57: Maximum discharge, that of Apr. 26, 1957; no flow at times. 

Maximum stage known since at least 1903, about 30.7 ft in 1908, from information by 

local residents. Flood of May 18, 1935, reached a stage of 29.7 ft, from floodmarks.

Remarks. Records good. Flow for period Oct. 1, 1956, to Apr. 20, 1957, was largely water 

diverted by pumping from Red River by city of Dallas for municipal use. Records furished by city of Dallas show diversion of water by pumping from Red River into Elm Fork 

Trinity River was- 29,820 acre-ft. At the end of the year the flow from 39.9 sq mi 

above this station was partly controlled by 16 floodwater detention reservoirs with 

a total combined capacity of 14,090 acre-ft below the flood spillway crests, of which 

12,170 acre-ft is floodwater detention capacity and 1,920 acre-ft is sediment pool capacity. Six of these reservoirs were constructed during the current year and have 

a total combined capacity below flood spillway crests of 3,136 acre-ft, of which 

507 acre-ft is sediment pool capacity. The capacity in these reservoirs allocated to 

sediment storage will be used for conservation storage until eliminated by sedimentation. The first floodwater detention reservoir in this basin was completed in October 

1954.

TRINITY RIVER BASIN 105

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-J- miles downstream from confluence of 

West and Elm Forks 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 

IS03 to September 1957 (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 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 . 54 years (1903-57), 1,498 cfs (1,084,000 acre-ft per year).

Extremes.--Maximum discharge during year, 75.300 cfs May 26 (gage height, 41.72 ft); minimum, 30 cfs Oct. 2 (gage height, 11.83 ft); minimum daily, 36 cfs Oct. 2.

1903-57: 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, 1920-57, 

1.2 cfs July 4, 1953.

Maximum stage known since at least 1840, that of May 25, 1908, Flood in 1866 

reached about the same stage.

Remarks. Records good. Flow largely regulated by Bridgeport Reservoir since 1932 

(see p. 82), Eagle Mountain Reservoir since 1934 (see p. 85 ), Benbrook and Grapevine 

Reservoirs since 1952 (see p. 87. 101), Lake Dallas since 1928 (see p. 96 ), GarzaLittle Elm Reservoir since 1954 (see p. 98 ), and several smaller reservoirs, all of 

which have a combined capacity of 2,323,000 acre-ft (revised). During year city of 

Dallas diverted 127,192 acre-ft of water above station for municipal use (32,900 acreft was diverted by pumping from Red River into Elm Fork Trinity River) and returned 

63,770 acre-ft of sewage effluent below station, from information by city of Dallas. 

Sewage effluent from cities of Fort Worth, Arlington, and Grand Prairie enters above 

station. Other diversions above station.

TRINITY RIVER BASIN 107

East Pork Trinity River near McKinney, Tex.

Location. Lat 33°12' 15". long 96°35'41", on right bank at downstream side of bridge on 

State Highway 24, 1.2 miles northeast of McKinney, Collin County, 2.8 miles downstream 

from Honey Creek, 7.2 miles upstream from Wilson Creek, and 22.4 miles upstream from 

Lavon Dam.

Drainage area. 188 sq mi.

Records available.--August 1949 to September 1957.

Gage. Water-stage recorder and concrete control. Datum of gage is 511.69 ft above mean 

sea level, datum of 1929.

Average discharge. 8 years (1949-57), 92.6 cfs (67,040 acre-ft per year).

Extremes.--Maximum gage height during year, 17.18 ft Apr. 26 (discharge not determined); 

maximum discharge measured, 23,900 cfs May 26 (gage height, 16.65 ft); no flow Nov. 27.

1949-57: Maximum gage height, 17.23 ft June 11, 1950 (discharge uncertain, previously published figure found to be in error); maximum discharge measured, that of 

May 26, 1957; no flow at times.

Maximum stage known since at least 1913, about 21.0 ft in April 1942, from information by local residents.

Revisions . Figures of maximum discharge and supplemental peak discharges for the 

water years 1950 and 1951 published in WSP 1178 and 1212, respectively, have been found 

to be unreliable and should not be used. Maximum discharges uncertain.

Remarks. Records fair except those above 1,800 cfs. which are poor. Low flow maintained 

by sewage effluent from U. S. Government Hospital. Small diversions for irrigation 

above station. At end of year flow from 25.0 sq mi above this station was partly controlled by 15 floodwater-detention reservoirs with a total combined capacity of 10,350 

acre-ft below flood spillway crests, of which 7,530 acre-ft is floodwater detention 

capacity and 2,820 acre-ft is sediment storage capacity. Two of these reservoirs were 

constructed during the current year and have a total combined capacity below flood 

spillway crests of 1,307 acre'-ft, of which 368 acre-ft is sediment pool capacity. The 

capacity in these reservoirs allocated to sediment storage will be used for conservation storage until eliminated by sedimentation. The first floodwater-detention 

reservoir in this basin was completed in August 1951.

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

in the water year 1950, superseding figures published in WSP 1178, are given herewith:

Discharge measurement made on this day. 

Field estimate made on this day.
108 TRINITY RIVER BASIN

Sister Grove Creek near Princeton, Tex.

Location. Lat 33°12', long 96°29', on right bank at downstream side of highway bridge, 

1.4 miles northeast of Princeton, Collin County, 2.3 miles downstream from Stiff Creek, 

5 miles upstream from mouth, and 15 miles upstream from Lavon Dam.

Drainage area. 115 sq mi.

Records available. September 1949 to September 1957.

Gage.--Water-stage recorder. Datum of gage is 487.52 ft above mean sea level, unadjusted 

(Corps of Engineers benchmark).

Average discharge.--8 years, 55.4 cfs (40,110 acre-ft per year).

Extremes. Maximum discharge during year, 9,080 cfs Apr. 26 (gage height, 16.28 ft), from 

rating curve extended above 3,800 cfs by logarithmic plotting; no flow for long periods. 

1949-57: Maximum discharge, that of Apr. 26, 1957; no flow at times. 

Maximum stage known since at least 1865, about 22 ft In July 1913, from information 

by local residents.

Remarks. Records good below 4,000 cfs, and fair above, fexcept those for period May 13 to 

June 7, which are poor. At end of year flow from 13.0 sq mi above this station was 

partly controlled by five floodwater detention reservoirs (all completed during 1953 

water year) with a total combined capacity of 4,680 acre-ft below flood spillway crests, 

of which 3,780 acre-ft Is floodwater detention capacity and 900 acre-ft is sediment 

pool capacity. The capacity in these reservoirs allocated to sediment storage will be 

used for conservation storage until eliminated by sedimentation.

Revisions (water years). WSP 1392: 1950, 195l(P).

Remarks.-Records fair except those above 20,000 cfs, which are poor. Flow largely 

 regulated by Lavon Reservoir since September 1953 (see p. 109]. At end of year flow 

from 45.1 sq mi above this station and below station near Lavon was partly controlled 

by 17 floodwater-detention reservoirs with a total combined capacity of 15,340 acre-ft 

below the flood spillway crests, of which 12,820 acre-ft is floodwater detention capacity and 2,520 acre-ft sediment storage capacity. The capacity in these reservoirs 

allocated to sediment storage will be used for conservation storage until eliminated 

by sedimentation. The first flood-water-detention reservoir in this basin was completed 

in February 1955.

112 TRINITY RIVER BASIN

Trinity River near Rosser, Tex.

Location.--Lat 32°25'40", long 96°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 1957.

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

1929. 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. 18 years (1939-57), 2,809 cfs (2,034,000 acre-ft per year).

Extremes. Maximum discharge during year, 56.000 cfs May 29 (gage height, 38.00 ft); minimum, 100 cfs Oct. 9 (gage height, 3.16 ft).

1924, 1938-57: 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 same as that 

of Apr. 23 or 24, 1942).

Remarks. Records good except those above 35,000 cfs and those for period of no gage-height 

record, which are fair. Flow largely regulated by reservoirs above Dallas and after 

September 1953 by Lavon Reservoir on East Fork Trinity River (see p. 109). At end of 

year, the flow from 77.2 sq mi above this station and below stations Trinity River at 

Dallas and East Fork Trinity River near Lavon was partly controlled by 30 floodwaterdetention reservoirs with a total combined capacity of 26,840 acre-ft below spillway 

crests, of which 22,330 acre-ft is floodwater detention capacity and 4,510 acre-ft is 

sediment storage capacity. The capacity in these reservoirs allocated to sediment 

storage will be used for conservation storage until eliminated by sedimentation. The 

first of these floodwater-detention reservoirs was completed in August 1953. 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. Diversions above station for irrigation and municipal supplies. Records of chemical analyses and water temperatures for the water year 1957 are given in WSP 1522.

TRINITY RIVER BASIN 115

Richland Creek near Richland, Tex.

Location.--Lat 31°57', long 96°25', on left bank at downstream side of bridge on U. S. 

Highway 75, 750 ft downstream from Texas and New Orleans Railroad bridge, 1 mile north 

of Richland, Navarro County, and 3.5 miles downstream from Pin Oak Creek.

Drainage area. 737 sq mi.

Records available. December 1924 to February 1925 (discharge measurements and monthly runoff only), March 1939 to September 1957.

Gage. Water-stage recorder. Datum of gage is 299.12 ft above mean sea level, datum of 

1929, Fort Worth supplementary adjustment of 1942. Dec. 11, 1924, to Feb. 11, 1925, 

chain gage at site 750 ft upstream at same datum. Since June 8, 1955, supplementary 

water-stage recorder, used for flood flows, 3,900 ft to right of main-channel gage.

Average discharge.--18 years (1939-57), 389 cfs (281,600 acre-ft per year).

Extremes. Maximum discharge during year, 44,600 cfs Apr. 21 (gage height, 23.11 ft); no 

flow at times.

1939-57: Maximum discharge, 58,900 cfs May 12, 1948 (gage height, 24.16 ft); no 

flow at times.

Maximum stage known since at least 1899, 25.5 ft in December 1913, from information 

by Texas and New Orleans Railroad Co.

Remarks. Records good above 100 cfs and fair below except those for period of no gageheight record, which are poor. At end of year, flow from 11.4 sq mi above this station 

was partly controlled by six floodwater-detention reservoirs with a total combined 

capacity of 4,769 acre-ft below flood spillway crests, of which 3,863 acre-ft is floodwater detention capacity and 906 acre-ft is sediment storage capacity. The capacity in 

these reservoirs allocated to sediment storage will be used for conservation storage 

until eliminated by sedimentation. The first floodwater-detention reservoir in this 

basin was completed in October 1956.

Chambers Creek near Corsicana, Tex.

Location. Lat 32°06'30", long 96°22'15", on right bank at downstream side of bridge on 

State Highway 31, 500 ft upstream from St. Louis Southwestern Railway bridge, 6,000 ft 

upstream from city of Corsicana diversion dam, 6 miles east of Corsicana, Navarro 

County, and 17 miles upstream from Richland Creek.

Drainage area. 971 sq mi.

Records available. March 1939 to September 1957.

Gage.--Water-stage recorder and concrete control. Datum of gage is 294.26 ft above mean 

sea level, datum of 1929.

Average discharge.--18 years, 443 cfs (320,700 acre-ft per year).

Extremes. Maximum discharge during year, 23,200 cfs May 24 (gage height, 25.94 ft); no 

flow at times.

1939-57: Maximum discharge, 48,000 cfs May 3, 1944 (gage height, 27.19 ft); no flow 

at times.

Maximum stage known since at least 1913, about 27.5 ft in December 1913, from information by local residents.

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

Storage began in 1956 in South Prong Reservoir (capacity, 13,500 acre-ft) on South Prong 

Waxahachie Creek above this station. At end of year flow from 5.38 sq mi above this 

station was partly controlled by three floodwater-detention reservoirs with a total 

combined capacity of 2,015 acre-ft below spillway crests, of which 1,548 acre-ft is 

floodwater detention capacity and 467 acre-ft is sediment storage capacity. The 

capacity of these reservoirs allocated to sediment storage will be used for conservation storage until eliminated by sedimentation. The first of these floodwaterdetention reservoirs was completed in April 1957. Prom information furnished by city 

of Corsicana, the city diverted approximately 3,330 acre-ft during year for municipal 

supply from pool in which gage is located. Discharge given herein does not include 

that pumped by the city.

TRINITY RIVER BASIN 117

gage

Trinity River near Oakwood , Tex.

Location. Lat 31°38'50", long 95°47'20", on left bank at downstream side of bridge on 

U. S. Highways 79 and 84, 1| miles upstream from International-Great Northern Railroad 

bridge, 6 miles northeast of Oakwood, Leon County, and at mile 313.

Drainage area. 12,912 sq mi.

Records available. --October 1923 to September 1924 (monthly discharge only), October 1924 

to September 1957. Records for January 1905 to September 1923, published in WSP 850 

and 878, have been found unreliable and should not be used. Gage-height records collected in this vicinity since 1904 are contained in reports of the U. S. Weather Bureau.

Gage. Water-stage recorder. Datum of gage is 175.06 ft above mean sea level, datum of 

1929, Fort Worth supplementary adjustment of 1942. Prior to July 15, 1932, chain 

at site l| miles downstream at datum 1.06 ft lower. July 15, 1932, to Oct. 7, 1934 

chain gage at present site and datum.

Average discharge. --34 years (1923-57), 4,824 cfs (3,492,000 acre-ft per year).

Extremes . --Maximum discharge during year, 91,800 cfs Apr. 28 (gage height, 48.87 ft); minimum, 84 cfs Oct. 14, 15.

1923-57: Maximum discharge, 153,000 cfs Apr. 29, 1942 (gage height, 51.64 ft); minimum observed, 28 cfs Aug. 24, 1925 (formerly published minimum has been superseded).

Flood of June 4, 1908, reached a stage of about 52.2 ft, present site and datum, 

from information by U. S. Weather Bureau (discharge, about 164,000 cfs).

Revisions. The minimum daily discharge for the water year 1924, published in 

WSP 878, is considered to be in error owing to doubtful gage-height record, and should 

not be used .

Remarks. --Records good. Some regulation by reservoirs above Dallas and by Lavon Reservoir 

on East Fork Trinity River (since Sept. 14, 1953). At end of year flow from 187 sq mi 

above this station and below stations at Trinity River at Dallas and East Pork Trinity 

River near Lavon was partly controlled by 61 flood water-detent ion reservoirs with a 

total combined capacity of 71,910 acre-ft below flood spillway crests, of which 59,620 

acre-ft is floodwater detention capacity and 12,290 acre-ft is sediment storage capacity. 

The capacity in these reservoirs allocated to sediment storage will be used for conservation storage until eliminated by sedimentation. The first of these floodwaterdetention reservoirs was completed in August 1953.

datum of 1929.

Average discharge. 18 years, 5,949 cfs (4,307,000 acre-ft per year).

Extremes. Maximum discharge during year, 103,000 cfs May 1 (gage height, 47.55 ft); minimum, 90 cfs Oct. 19.

1939-57: Maximum discharge, 146,000 cfs May 1, 1942 (gage height, 48.58 ft); minimum observed, 87 cfs July 27, 1956.

Maximum stage known prior to construction of levees in 1916, about 45.0 ft in May 

1890 (discharge not determined), from information by local residents. Flood of June 9, 

1908, reached a stage of 44.3 ft, from floodmarks and from information by local residents. Flood of May 27, 1930, reached a stage of 46.7 ft, from floodmark (flow confined within levees).

Remarks. Records good. Some regulation by reservoirs above Dallas and by Lavon Reservoir 

on East Fork Trinity River since Sept. 14, 1953. Diversions above station for municipal supplies, industrial use, and irrigation.

130 SAN JACINTO RIVER BASIN

Gage 

of

Barker Reservoir near Addicks, Tex.

Location. Lat 29°46'05", long 95°38'45", at dam on Buffalo Bayou 45 ft upstream from 

reservoir outlet works, 1,160 ft upstream from Addicks-Howell County road, 1.1 miles 

south of Addicks, Harris County, and 1.2 miles upstream from South Mayde Creek. 

Upper gage, lat 29°43'10", long 95 C 44'00", on Buffalo Bayou, 2.8 miles west of Clodine, 

Port 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 1957.

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

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

Extremes. Maximum gage height at dam during year, 83.4 ft Mar. 18, 19 (contents, 

344 acre-ft); maximum at upper gage, 93.6 ft Mar. 18.

1945-57: 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 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 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.

Cooperation. Capacity table and gage-height record at dam furnished by Corps of Engineers.

Qage height and contents, at indicated time when flood runoff was partly stored in reservoir, 

during periods in March and April 1957

Maximum stage known, 89.9 ft in December 1935 at bridge on U. S. Highway 90, 2,700 

ft downstream from outlet works, from information by Corps of Engineers. This flood, 

from floodmarks, from information by local residents, reached a stage of 109.3 ft, 

0.2 mile downstream, and 0.1 mile to right of gage on South Mayde Creek; and a stage 

of 104.5 ft, 1,900 ft to left and 700 ft upstream from gage on Langham Creek.

Remarks. Reservoir is formed by rolled-fill earthen-type dam 61,166 ft long. Dam completed in the fall of 1948. 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 gates; the 2 outer conduits are controlled by single 

vertical-lift steel gates. All gates will remain closed except during recession of 

large floods or during emergencies. Capacity, 188,030 acre-ft between elevations 

73.0 ft (bottom of conduits) and 113.0 ft (top of design flood pool). No constructed 

emergency spillways; runoff considerably in excess of designed capacity will be discharged around ends of dam. Elevations and contents not published for floods that do 

not produce an elevation of 79.0 ft (top of outlet structure) or higher at dam.

Cooperation. Capacity table and elevation record at dam furnished by Corps of Engineers.

Elevation and contents, at Indicated time when flood runoff was partly stored In reservoir,

142 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 1957.

Gage.--Water-stage recorder. Datum of gage is 1.31 ft below mean sea level, datum of 1929.

Average discharge. 12 years (1945-57), 163 cfs (118,000 acre-ft per year).

Extremes. Maximum discharge during year, 10,600 cfs May 10 (gage height, 31.25 ft); minimum daily, 2.1 cfs Mar. 2.

1944-57: Maximum discharge, that of May 10, 1957; minimum daily, 0.3 cfs at times 

in 1955-56.

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 

stage of Brazos River at East Columbia and stage at this station. Peak of May 10, 1957, 

is result of overflow from Brazos River.

Remarks.--Records good. Diversions above station for irrigation. A large part of 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 Brazos River during 

periods of flood flow.

Revisions (water years).--WSP 1392: 1947.

BRAZOS RIVER BASIN 153

Clear Fork Brazos River at Nugent, Tex.

Location. Lat 32°41', long 99°40', on right bank 33 ft (revised) downstream from pier of 

county road bridge in Nugent, Jones County, and 4 miles upstream from Headman Creek.

Drainage area.--2,220 sq mi.

Records available. February 1924 to September 1957.

Gage. Water-stage recorder. Datum of gage is 1,531.91 ft above mean sea level (levels by 

Brazos River Authority). Prior to Dec. 12, 1933, staff gage at site 575 ft downstream 

at same datum.

Average discharge. 33 years, 138 cfs (99,910 acre-ft per year).

Extremes. Maximum discharge during year, 19,500 cfs May 26 (gage height, 24.17 ft); no 

flow at times.

1924-57: Maximum discharge observed, 47,000 cfs Sept. 8, 1932 (gage height, 27.05 

ft, site then in use), from rating curve extended above 25,000 cfs; no flow at times.

Maximum stage known, about 30.0 ft in 1876, from information by local residents. 

Floods in 1900 and May 1923 reached stages of about 24 and 24.5 ft, respectively, from 

information by local residents.

Remarks. Records good. Some regulation by reservoirs in Elm Creek basin (see p. 196) and 

Lakes Sweetwater and Trammel in Sweetwater Creek basin, which have a combined capacity 

of about 114,700 acre-ft. Diversions above station for municipal supply and oilfield 

operation materially affect low flow. During the year the city of Abilene diverted 

2,749 acre-ft of water into Fort Phantom Hill Reservoir from the river above station.

158 BRAZOS RIVER BASIN

Brazos River near Palo Pinto, Tex.

Location. Lat 32°51'45", long 98 "18'10", on right bank 35 ft upstream from bridge on Palo 

Pinto-Graford highway, 300 ft downstream from Dark Valley Creek, 6f 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 1957. Published as "near Mineral Wells" 

1924-33.

Gage. Water-stage recorder. Datum of gage is 831.23 ft above mean sea level, datum of

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

lower.

Average discharge . 33 years (1924-57), 1,806 cfs, revised (873,100 acre-ft per year).

Extremes. 1924-25: Maximum discharge during year, 45,200 cfs (revised) Sept. 13 (gage

 height, 15.6 ft, from graph based on gage readings); no flow Mar. 4 to Apr. 11.

1956-57: Maximum discharge during year, 85,400 cfs Apr. 29 (gage height, 28.87 ft); 

minimum daily, 14 cfs Oct. 26.

1924-57: Maximum discharge, 95,600 cfs June 16, 1930 (gage height, 30 ft, present 

gite and datum); no flow at times.

According to information received from the Corps of Engineers in 1936, the greatest 

flood known prior to that date occurred in 1876 and was several feet higher than any 

other flood occurring between 1876 and 1936.

Revisions. Figures of maximum discharge for the water years 1925 and 1929 have been 

revised to 45,200 cfs Sept. 13, 1925 (gage height, 15.6 ft, from graph based on gage 

readings) and 53,500 cfs Sept. 10, 1929 (gage height, 17.0 ft, from graph based on gage 

readings), superseding those published in WSP 608 and 688, respectively.

Remarks. Records good. Flow since 1941 largely regulated by Possum Kingdom Reservoir 

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

having a combined capacity of about 946,500 acre-ft. Many small diversions above 

Possum Kingdom Reservoir for irrigation, municipal supply and oilfield operation.

Revisions. Revised figures of discharge, in cubic feet per second, for the water years 

1924-25, 1929, and 1932-34, superseding those published in WSP 588, 608,688, 733, 

748, and 788, are given herewith. Complete table of daily discharge is given for the 

water year 1925, but only revised figures are given for other years. Daily discharges 

for period Nov. 16-30, 1933, supersede daily discharges previously published for the 

partial month of November for station near Palo Pinto.

160 BRAZOS RIVER BASIN

Palo Pinto Creek near Santo, Tex.

Location. Lat 32°38', long 98°11', on left bank 0.5 mile upstream from Texas and Pacific 

Railway bridge, 1.4 miles downstream from Big Sunday Creek, 2.6 miles northeast of 

Santo, Palo Pinto County, 2.8 miles upstream from Wusser Creek, and 7.0 miles upstream 

from mouth.

Drainage area. 567 sq mi.

Records available.--November 1924 to September 1925 (gage heights only), April 1951 to September 1957.

Gage. Water-stage recorder. Datum of gage is 762.63 ft above mean sea level, datum of 

1929. Nov. 20, 1924, to Sept. 30, 1925, combination inclined and vertical staff gage 

at present site and datum.

Average discharge. 6 years, 88.7 cfs (64,220 acre-ft per year).

Extremes. Maximum discharge during year, 45,100 cfs May 26 (gage height, 31.05 ft, from 

floodmark), from rating curve extended above 18,000 cfs on basis of slope-area determination of peak flow; no flow at times.

1951-57: Maximum discharge, that of May 26, 1957; no flow at times.

Maximum stages since at least 1880 occurred May 8, 1922, and May 26, 1957. Flood of 

May 8, 1922, reached about same stage as in 1957, from information by the Texas and 

Pacific Railway Co., but probably was slightly lower according to statements by local 

residents.

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

No large diversion above station.

BRAZOS RIVER BASIN 

3razos River near Glen Rose, Tex.

161

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 1957.

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

1929. 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 at same datum.

Average discharge.--34 years, 1,590 cfs, revised (1,151,000 acre-ft per year).

tremes. Maximum discharge during year, 87,400 cfs May 27 (gage height, 30.02 ft, from 

floodmark at regular gage, 33.89 ft at flood gage); minimum daily discharge, 12 cfs 

Oct. 6.

1923-57: Maximum discharge, 97,600 cfs May 18, 1935; maximum gage heights, those of 

May 27, 1957;. no flow at times prior to construction of Possum Kingdom Dam.

Maximum stage known prior to 1957, about 30.0 ft May 8 or 9, 1922, from information 

by local residents.

Revisions. The figures of maximum discharge for some water years have been revised, 

as shown in the following table. They supersede figures published in the water-supply 

papers indicated.

Remarks. Records good. Flow since 1941 largely regulated by Possum Kingdom Reservoir

(see p. 15?) except during major floods, and by several smaller reservoirs in Clear Pork 

and other basins, having a combined capacity of about 946,000 acre-ft. Many diversions 

above station for irrigation, municipal supply, and oilfield operation. Change in gageheight-discharge relationship due to construction of low-water bridge about 1945 just 

downstream from regular gage.

Revisions (water years). WSP 1058: 1932. Revised figures of discharge, in cubic feet per 

second, for high-water periods in the water years 1946, 1947, and 1949, superseding

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

At end of water year flow from 45.4 sq mi above this station was partly controlled by 

13 floodwater-detention reservoirs with total combined capacity of 15,150 acre-ft below 

flood spillway crest, of which 13,340 acre-ft is floodwater-detention capacity and 

1,810 acre-ft is sediment-storage capacity. Five of ttiese reservoirs were constructed 

during the current year and have a total combined capacity below flood spillway crests 

of 7,312 acre-ft, of which 832 acre-ft is sediment pool capacity. The capacity in 

these reservoirs allocated to sediment storage will be used for conservation storage 

until eliminated by sedimentation. Small diversions above station.

Revisions (water years) . WSP 788: 1924-26, 1928, 1930. WSP 1058: 1945(M). Revised

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 ml, approximately, of which 9,240 sq ml Is probably noncontributing.

Records available. September 1898 to September 1957 (January 1912 to September 1914 

monthly records only, published In WSP 850). Gage-height records collected In this 

vicinity since 1900 are contained In reports of U. S. Weather Bureau.

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

1929, supplementary adjustment of 1942. Sept. 14, 1898, to Mar. 28, 1918, and May 6, 

1922, to Feb. 12, 1934, staff or chain gages at several sites within about 350 ft of 

present site at same datum. May 28, 1918, to May 5, 1922, and Feb. 13, 1925, to 

Sept. 29, 1934, water-stage recorder at site about 300 ft downstream at same datum.

Average discharge. 59 years, 2,550 cfs, revised (1,846,000 acre-ft per year).

Extremes. Maximum and minimum discharges for the water years 1901-5, 1915, 1925-29, and 

1957, some of which have been revised, are contained In the following table. They 

supersede figures published In the water-supply papers Indicated.

1904, to Jan. 10, 1905.

1898-1957: Maximum discharge, 246,000 cfs Sept. 27, 1936 (gage height, 40.90 ft, 

levee on left bank was overtopped and broken by flood); minimum for periods of dally record, 1898-1911, 1914-57, no flow Aug. 20, 21, 1918, and probably for several days in 

August 1923.

Maximum stage 1854-97, 34.6 ft May 28, 1885. A stage of 39.7 ft was reached Dec. 3, 

1913, when levee on left bank was broken by flood, from information by U. S. Weather 

Bureau.

Remarks. Records fair. Flow regulated by Possum Kingdom and Whltney Reservoirs on Brazos 

River (see p. 157,165), several small reservoirs In Clear Fork and other basins (combined capacity, 221,800 acre-ft), and Lake Waco on Bosque River (capacity, 22,000 acreft); total combined capacity of all reservoirs, about 2,986,000 acre-ft (corrected), of 

which 1,630,500 acre-ft is flood-control storage in Whltney Reservoir. A siltatlon survey of Lake Waco by the Soil Conservation Service of the U. S. Department of Agriculture 

In December 1947 Indicates a 44.07 percent capacity loss from siltatlon since storage 

began in April 1930. Many small diversions above station for municipal supply, irrigation, and oilfield operation do not appreciably affect flow. The city of Waco discharged an average of about 10 cfs of sewage effluent 2-J- miles below gage.

Revisions (water years).- WSP 568: Drainage area. WSP 850 and WSP 878: 1899-1900, 1907-9 

(monthly and yearly summaries only). Revised figures of discharge for the water years 

1901-5, 1910, 1915, 1927-29, superseding those published in WSP 50, 66, 75, 84, 99, 132, 

174, 288, 408, 648, 668, 688, and 850, are given herein. Complete tables of dally discharges are given for the water years 1901-5, and 1915, but only revised discharges are 

given for other water years.

BRAZOS RIVER BASIN 181

San Gabriel River at Georgetown, Tex.

Location. Lat 30°39'10", long 97°39'20", on left bank 100 ft downstream from MissouriKansas-Texas Railroad bridge, l-J miles downstream from confluence of North and South 

Forks, and if miles northeast of Georgetown, Williamson County.

Drainage area.--415 sq mi.

Records available.--February 1924 to August 1925, July 1934 to September 1957.

Gage.--Water-stage recorder and concrete control. Datum of gage is 643.24 ft above mean 

sea level, datum of 1929. Feb. 27, 1924, to Aug. 31, 1925, staff gage at site 1 mile 

upstream at different datum.

Average discharge.--23 years (1934-57), 130 cfs (94,120 acre-ft per year).

Extremes. Maximum discharge during year, 155,000 cfs Apr. 24 (gage height, 31.89 ft in 

gage well, 34.10 ft, from floodmarks), from rating curve extended above 24,000 cfs on 

basis of contracted-opening determination of peak flow; no flow Oct. 1, 2, 11-14.

1924-25, 1934-57: Maximum discharge, that of Apr. 24, 1957; no flow at times in 

1954-56.

Maximum stage since at least 1869, 36.1 ft (revised) Sept. 10, 1921, present site and 

datum (on basis of levels to floodmarks at sites 1 mile upstream and 1 mile downstream 

from gage, which show 1921 flood was 2.0 ft higher than that of 1957); discharge, 

160,000 cfs, by slope-area determination of peak flew.

Remarks.--Records fair. Several small diversions have some effect on low flow which is 

also regulated at times by gates in recreation dam 3,000 ft upstream.

194 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, Port Bend County, &| miles downstream from 

Gulf, Colorado and Santa Pe Railway bridge, and at mile 67.

Drainage area. 44,100 sq mi, approximately, of which 9,240 sq ml is probably noncontributing.

Records available. May 1949 to September 1957.

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

Houston supplementary adjustment of 1943.

Average discharge. 8 years, 4,139 cfs (2,997,000 acre-ft per year).

Extremes. Maximum elevation during year, 59.17 ft May 6, 7 (discharge not determined); 

minimum discharge, 166 cfs Jan. 13, 14.

1949-57: Maximum elevation, that of May 6, 7, 1957 (discharge not determined); 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. Prom 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 of 1913.

Remarks. Records fair. Plow regulated by reservoirs above Bryan. Considerable water 

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

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.

COLORADO RIVER BASIN

Location. Lat 31°27'10", long 100°24'40", on right bank 0.5 mile downstream from confluence of North Concho and South Concho Rivers and 1.8 miles southeast of San Angelo, Tom 

Green County.

Drainage area. 4,492 sq ml, of which 275 sq ml is probably noneontrlbut Ing.

Records available. September 1915 to September 1957.

Gage. Water-stage recorder. Datum of gage is 1,776.79 ft above mean sea level, datum of 

1929. Prior to Aug. 11, 1917, staff gage at same site and datum.

Average discharge. 42 years, 162 cfs, revised (117,300 acre-ft per year).

Extremes.--Maximum discharge during year, 106,000 cfs May 9 (gage height, 39.30 ft in gage

 well, 39.8 ft, from floodmarks); minimum daily, 0.1 cfs Mar. 9, 10, 12.

1915-57: Maximum discharge, 230,000 cfs Sept. 17, 1936 (gage height, 46.6 ft, from 

floodmarks), from rating curve extended above 51,000 cfs on basis of slope-area determinations at gage heights 42.6 and 46.6 ft; no flow at times in 1921, 1952-53.

Maximum stage known since 1854, 47.5 ft Aug. 6, 1906 (discharge, about 246,000 cfs), 

from information by local resident. Other large floods are known to have occurred in 

August 1882 and April 1900.

Remarks Records good except those for periods of fragmentary, or doubtful or no gageheight record, which are fair. Many diversions above station for irrigation and municipal supply. Maximum discharge for the year was not materially affected by regulation 

from reservoirs upstream. At times, low and medium flows are regulated by Lake Nasworthy on South Concho River (see p. 259). Since 1952 flow of North Concho River is 

largely regulated by San Angelo Reservoir (see p. 217).

COLORADO RIVER BASIN 221

Concho River near Paint Rook, Tex.

Location. Lat 31°31', long 99°55', near left bank on downstream side of pier of bridge 

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

Drainage area.--5,538 sq mi, of which 275 sq mi is probably noncontributing.

Records available. September 1915 to September 1957.

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 present datum and May 19, 1938, to Jan. 14, 1940, wire-weight gage at present site 

and datum.

Average discharge.--42 years, 218 cfs (157,800 acre-ft per year).

Extremes.--Maximum discharge during year, 79,300 cfs May 10 (gage height, 31.95 ft); minimum daily, 0.2 cfs at times.

1915-57: 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 determination 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 of no gage-height record, which are fair, 

and those for periods when the stage was below the crest of control dam, which are 

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

slightly regulated by Lake Nasworthy on South Concho River (see p. 259), and by San 

Angelo Reservoir on the North Concho River (see p. 217).

Revisions (water years). WSP 458: 1915-16. WSP 568: 1919-20. WSP 588: Drainage area.

floodmarks); no flow most of time.

Maximum stage known since at least 1890, 21.3 ft July 23, 1938 (discharge, 33,600 

cfs, by slope-area determination of peak flow). Flood in 1906 reached a stage of about 

21.0 ft, from information by local resident.

Remarks. Records fair. The flow from 19.9 sq mi above this station is partly controlled 

by 5 floodwater detention reservoirs with a total combined capacity of 5,810 acre-ft 

below the flood spillway crests, of which 5,200 acre-ft is floodwater detention capacity 

and 610 acre-ft is sediment storage capacity. The capacity in these reservoirs allocated to sediment storage will be used for conservation storage until eliminated by 

sedimentation. Station operated as part of the Deep Creek basin hydrologic cooperative 

program of the Geological Survey and Soil Conservation Service to evaluate rainfallrunoff relation, soil conservation practices, and the effects of flood-detention structures.

COLORADO RIVER BASIN 227

Herds Creek near Valera, Tex.

Location. Lat 31°50', long 99°33', on left bank about 7,500 ft downstream from Herds Creek 

Reservoir, 5.5 miles north of Valera, Coleman County, and 7.0 miles west of Coleman.

Drainage area. 53 sq mi, approximately.

Records available. April 1947 to September 1957.

Gage. Water-stage recorder. Datum of gage is 1,819.88 ft above mean sea level, datum of 

1929 (Corps of Engineers benchmark).

Average discharge.--10 years, 1.95 cfs (1,410 acre-ft per year).

Extremes. Maximum discharge during year, 878 cfs May 12 (gage height, 6.60 ft); no flow 

for long periods.

1947-57: Maximum discharge, 3,860 cfs Apr.30, 1956 (gage height, 14.73 ft, from 

rating curve extended above 1,900 cfs by logarithmic plotting); no flow at times each 

year.

Maximum stage known, 23.0 ft July 3, 1932, from information by local residents 

(discharge not determined). Flood in July or September 1900 reached a stage 3.7 ft 

higher than that of July 1932 at a site 12 miles downstream at Coleman, from information 

by local residents.

Remarks.--Records good. Flow largely regulated by Herds Creek Reservoir (see preceding 

page). At times runoff results from rainfall on area between reservoir and gage site.

COLORADO RIVER BASIN

Hords Creek at Coleman, Tex.

Location.--Lat 31°51', long 99°26', near right bank at downstream side of pier of bridge 

on U. S. Highways 84 and 283 and State Highway 206, 1 mile north of Coleman, Coleman 

County, 2.5 miles downstream from Batchelor Creek, and 12 miles downstream from Hords 

Creek Dam.

Drainage area. 107 sq mi, of which 48 sq mi is above Hords Creek Dam.

Records available. October 1940 to September 1957.

Gage. Water-stage recorder. Datum of gage is 1,676.83 ft above mean sea level, datum of 

1929, Fort Worth supplementary adjustment of 1942. Prior to May 23, 1946, staff gage at 

site 3,700 ft downstream at datum 6.38 ft lower.

Average discharge. 17 years, 9.69 cfs (7,020 acre-ft per year).

Extremes . 1955-5*6: Maximum discharge during water year, 25,100 cfs Apr. 30 (gage height, 

21.50 ft), from rating curve extended above 4,800 cfs on basis of slope-area determination at gage height 16.50 ft and contracted-opening determination of peak flow; no flow 

most of time.

1956-57: Maximum discharge during water year, 4,900 cfs May 23 (gage height, 11.95 

ft); no flow most of time.

1940-57: Maximum discharge, that of Apr. 30, 1956; no flow at times. 

Maximum stage known since at least 1876 occurred in June or September 1900, and 

reached a stage about 6.3 ft higher than that of Apr. 30, 1956, at a point near municipal light and power plant about 6,000 ft downstream from the present gage. Flood of 

July 3, 1932, reached a stage about 2.6 ft higher than that of Apr. 30, 1956, at the 

same downstream point. Data pertaining to stage of floods in 1900 and 1932 from information by local residents.

Remarks.--Records good. Since 1948 flow largely regulated by Hords Creek Reservoir (see 

p. 226), from which city of Coleman obtains part of its municipal water supply. Water 

was spilling or being released from Hords Creek Reservoir during periods Apr. 30 to 

May 5, 1956, and May 13 to June 4, 1957. Maximum discharge on Apr. 30, 1956, was not 

affected by spill or release from Hords Creek Reservoir. Maximum discharge on May 23, 

1957, was only slightly affected by flow released from Hords Creek Reservoir.

236 COLORADO RIVER BASIN

Brady Creek at Brady, Tex.

Location. Lat 31°08'15", long 99°19'55", on left bank just upstream from bridge on U. S. 

Highway 377 on North Bridge Street in Brady, McCullough County, 0.4 mile downstream 

from Live Oak Creek.

Drainage area. 575 sq mi.

Records available.--May 1939 to September 1957.

Gage. Water-stage recorder. Datum of gage is 1,646.50 ft above mean sea level, datum of 

1929. Prior to July 9, 1940, staff gage at site 3,600 ft upstream at datum 8.24 ft 

higher.

Average discharge . 18 years, 27.7 cfs (20,050 acre-ft per year).

Extremes.--Maximum discharge during year, 8,920 cfs May 12 (gage height, 13.96 ft); no 

flow for many days.

1939-57: Maximum discharge, 39,100 cfs Sept. 10, 1952 (gage height, 24.80 ft); no 

flow at times.

Maximum stage known since at least 1930, 29.1 ft July 23, 1938, present site and 

datum (discharge at site 5 miles downstream, 86,000 cfs by slope-area determination of 

peak flow). Flood on Oct. 6, 1930, reached a stage of 27.47 ft, present site and datum 

from information by local residents.

Revisions. Figures of maximum discharge for the water years 1941 and 1951 have 

been revised to 15,500 cfs Apr. 27, 1941 (gage height, 16.81 ft) and 13,200 cfs 

May 24, 1951 (gage height, 15.92 ft), superseding those published in WSP 928 and 1212, 

respectively.

Remarks. Records good above 5 cfs and fair below. City of Brady has permit to divert 

730 acre-ft per year for municipal use. At end of year, flow from 106 sq mi above 

this station was partly controlled by 18 floodwater detention reservoirs with a total 

combined capacity of 35,490 acre-ft below flood spillway crests, of which 33,400 acreft is floodwater detention capacity and 2,090 acre-ft is sediment storage capacity. 

Five of these reservoirs were constructed during the current year and have a total 

combined capacity below flood spillway crests of 12,950 acre-ft, of which 739 acre-ft 

is sediment pool capacity. The capacity in these reservoirs allocated to sediment 

storage will be used for conservation storage until eliminated by sedimentation.

Location.--Lat 31°13'05", long 98°33'50", on left bank at downstream side of pier of bridge 

on U. S. Highway 190, 5.2 miles downstream from San Saba River, 9.2 miles east of San 

Saba, San Saba County, and at mile 474.

Drainage area.--30,600 sq mi, approximately, of which 11,900 sq mi is probably noncontributing.

Records available.--October 1915 to October 1922 (published as "near Chadwick"), October 

1923 to December 1934 (published as "near Tow"), August 1930 to September 1957.

Gage.--Water-stage recorder. Datum of gage is 1,096.22 ft above mean sea level, datum of 

1929. October 1915 to October 1922 staff gage at site 1.2 miles upstream at datum 

1.92 ft higher. October 1923 to Apr. 16, 1925, chain gage and Apr. 17, 1925, to December 1934 (corrected) water-stage recorder, at site 44 miles downstream at different 

datum. Aug. 30, 1930, to Mar. 21, 1940, water-stage recorder and Mar. 21 to May 23, 

1940, staff gage, at site 2,230 ft downstream at same datum.

Average discharge.--39 years (1916-19, 1920-22, 1923-57), 1,475 cfs, revised (1,068,000 

acre-ft per year).

Extreme a.- -Maximum discharge during year, 66,200 cfs May 14 (gage height, 37.34 ft); minimum, 7.4 cfs Oct. 2, 3.

1915-22, 1923-57: Maximum discharge, 224,000 cfs July 23, 1938 (gage height, 63.2ft, 

present site, based on floodmarks at site then in use); no flow Aug. 27-31, 1954.

Maximum stage known during period 1878 to July 22, 1938, 58.4 ft Sept. 25, 1900 (discharge, 184,000 cfs), present site, from floodmarks at former site.

Remarks.--Records good. Diversions above station for irrigation, municipal use, and oilfield operation. Flow slightly regulated by 5 reservoirs in the Colorado and Concho 

Rivers and Oak Creek basins above Winchell, and by 2 reservoirs in the Pecan Bayou 

basin; combined capacity, 838,300 acre-ft. At the end of the year the flow from 138 sq mi 

above this station and below the Winchell station was partly controlled by 27 floodwater detention reservoirs with a total combined capacity of 44,960 acre-ft below the 

flood spillway crests, of which 41,780 acre-ft is floodwater detention capacity and 

3,180 acre-ft is sediment storage capacity. The capacity in these reservoirs allocated 

to sediment storage will be used for conservation storage until eliminated by sedimentation. The first of these floodwater detention reservoirs was completed in January 1952. 

Records of chemical analyses, water temperatures, and suspended sediment loads for the 

water year 1957 are given in WSP 1522.

248 COLORADO RIVER BASIN

Barton Springs at Austin, Tex.

Location. Lat 30°15'50", long 97°46'15" (revised). 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 1957 (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, 88.2 cfs Sept. 2.7; minimum measured, 

9.69 cfs Mar. 20. I

1894-1957: Maximum discharge measured, 166 cfs May 10, 1941; minimum measured, 

9.59 cfs Mar. 29, 1956.

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 the springs 

caused by the swimming pool at main spring being full has an appreciable effect on the 

flow of the springs.

COLORADO RIVER BASIN 

Waller Creek at 38th Street, Austin, Tex.

249

Location. Lat 30°17'49", long 96°43'36", on right bank 200 ft upstream from bridge at 

East 38th Street at Austin, Travis County, 1.1 miles upstream from West Branch of 

Waller Creek, and 3.3 miles upstream from Colorado River.

Drainage area. 2.31 sq mi.

Records available. April 1955 to September 1957.

Gage. Water-stage recorder and concrete control. Datum of gage is 555.44 ft above mean 

sea level, datum of 1929, Fort Worth supplementary adjustment of 1942.

Extremes. 1955: Maximum discharge during period April to September, 186 cfs May 18 

(gage height, 4.38 ft); no flow at times.

1955-56: Maximum discharge during water year, 108 cfs May 1 (gage height, 3.94 ft); 

no flow at times.

1956-57: Maximum discharge during water year, 596 cfs May 26 (gage height, 5.75 ft); 

no flow at times.

1955-57: Maximum discharge, that of May 26, 1957; no flow at times.

Remarks. Records good. Flow regulated by a small reservoir at St. Mary's Academy on 

West 41st Street, and a small swimming pool at the academy which is drained into the 

creek every week or two during the summer. Other swimming pools drain into the creek, 

causing rises which are not from rainfall.

Drainage area.--38,400 sq mi, approximately, of which 11,900 sq mi Is probably noncontrlbuting.

Records available.--February 1898 to September 1957. Gage-height records collected In 

this vicinity since 1903 are contained in reports of U. S. Weather Bureau.

Gage.--Water-stage recorder. Datum of gage is 407.28 ft above mean sea level, datum of 

1929. Prior to June 18, 1915, combination staff and chain gages in vicinity of Congress Avenue Bridge, 4.0 miles upstream at datum 14.6 ft higher. June 18, 1915, to 

Apr. 21, 1918, water-stage recorder (pressure type) In basement near left end of Congress Avenue Bridge at datum 14.6 ft higher. Apr. 26, 1918, to June 19, 1939, waterstage recorder at Congress Avenue Bridge at datum 14.6 ft higher.

Average discharge.--59 years, 2,491 cfs (1,803,000 acre-ft per year).

Extremes.--Maximum discharge during year, 40,800 cfs June 4 (gage height, 17.60 ft); minimum daily, 131 cfs Jan. 17.

1898-1957: Maximum discharge, 481,000 cfs June 15, 1935 (gage height, 45.0 ft, 

present site and datum, from floodmark); minimum, 13 cfs Aug. 18, 1918.

Maximum stage known since at least 1843, 46.0 ft July 7, 1869, present site and 

datum (adjusted to present site on basis of record for flood of June 15, 1935), determined from information concerning stage at former site furnished by Dean T. U. Taylor.

Remarks. Records good. Flow largely regulated by Buchanan Reservoir and Lake Travis (see 

p. 241,247), and other smaller reservoirs, having a combined capacity of 3,979,000 

acre-ft. About 36,000 acres irrigated above station. During year city of Austin diverted an average of about 43 cfs for municipal use above station and returned about 

20 cfs of treated sewage below station. Many other diversions above Buchanan Reservoir 

for irrigation, municipal supply, and oilfield operations. Records of chemical analyses and water temperatures for the water year 1957 are given in WSP 1522.

Revisions (water years).--WSP 528: 1900(M). WSP 1342: Drainage area.

Orleans Railroad bridge, 12 miles upstream from Jones Creek, and at mile 67.

Drainage area.--41,380 sq mi, approximately, of which 11,900 sq mi is probably noncontributing.

Records available.--July 1916 to September 1925, July and August 1938 (flood discharge 

measurements only), October 1938 to September 1957. June to November 1901 and May to 

September 1902, daily records published in U. S. Department of Agriculture, Office of 

Experiment Stations, Bulletin Nos. 119 and 133. Gage-height records, collected in this 

vicinity since 1935, are contained in reports of U. S. Weather Bureau.

Gage.--Wire-weight gage read twice daily. Datum of gage is 65.42 ft above mean sea level, 

d"atum of 1929. Prior to Mar. 19, 1919, staff gage and Mar. 19, 1919, to Sept. 30, 1925, 

water-stage recorder, at sifce about 700 ft upstream at different datum.

Average discharge.--24 years (1919-21, 1922-25, 1938-57), 2,792 cfs (2,021,000 acre-ft per 

year).

Extremes.--Maximum discharge during year, 54,200 cfs Apr. 30 (gage height, 28.90 ft); minimum daily, 85 cfs Dec. 8.

1919-25, 1938-57: Maximum discharge observed, 100,000 cfs July 3, 1940 (gage 

height, 35.99 ft); no flow Aug. 6, 1925 (result of pumping).

Maximum stage known, 38.9 ft Dec. 8, 1913, present datum, from information by local 

residents; below Wharton floodwater combined with floodwater of Brazos River. Flood of 

about July 12, 1869, reached about same height. Flood of June 20, 1935, reached a 

stage of 38.2 ft, present datum (discharge, 159,000 cfs, from rating curve extended 

above 145,000 cfs), furnished by U. S. Weather Bureau. Flood of July 30, 1938, reached 

a stage of 37.4 ft, present datum, observed by Geological Survey engineers (discharge, 

145,000 cfs) .

Remar.-cs.--Records good. Many diversions above station for irrigation, municipal supply, 

and oilfield operation. Regulation same as that for Colorado River at Austin. Records 

of chemical analyses and water temperatures for the water year 1957 are given in 

WSP 1522.

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

RevlslonsTwater years).--WSP 878: 1938(M). WSP 1342: Drainage area.

Capacity at top of 600-foot emergency spillway (gage height, 41.0 ft) not determined. 

There is no dead storage. Beginning 1955 figures of contents and the capacities shown 

herein have been adjusted for sedimentation. Siltation surveys made by the U. S. 

Department of Agriculture, Soil Conservation Service, in December 1938 and May 1953 

show that for the period March 1930 to December 1938, 1,191 acre-ft of silt was deposited, and from December 1938 to May 1953 an additional 1,023 acre-ft was deposited, 

making a total siltation of 2,214 acre-ft at gage height 32.2 ft. Water is used for 

San Angelo municipal supply.

GUADALUPE RIVER BASIN 269

Comal River at Hew Braunfels, Tex.

Location. Lat 29°42'05", long 98°07'10", on right bank 200 ft upstream from San Antonio 

Street viaduct in New Braunfels, Comal County, and 1.1 miles upstream from mouth.

Drainage area. 117 sq mi. Normal flow of river comes from springs, drainage area of 

stream not applicable.

Records available.--1882 to September 1957 (1882 to November 1927, discharge measurements 

only).

Gage. Water-stage recorder and concrete control since Oct. 1, 1955. Datum of gage is 

582.80 ft above mean sea level, datum of 1929.

Average discharge. 25 years (1932-57), 284 cfs (205,600 acre-ft per year).

Extremes.--Maximum discharge during year, 8,610 cfs May 27 (gage height, 17.45 ft), from 

rating curve extended above 600 cfs on basis of rating described below; minimum daily, 

11 cfs Oct. 3.

1927-57: Maximum discharge, 35,000 cfs Sept. 11, 1952 (gage height, 36.14 ft, from 

floodmark), from rating curve extended above 1,600 cfs on basis of slope-area determinations at gage heights 14.87 and 36.14 ft; minimum daily, 5.5 cfs June 7, 1956.

Maximum stage known since at least 1869, 37.65 ft Oct. 17, 1870, gage datum, from 

floodmark about half a mile downstream (probably some backwater from Guadalupe River).

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

fluctuations from steam powerplant half a mile upstream. Prior to June 7, 1956, entire 

flow of river from Comal Springs, about 1 mile upstream, except during periods of local 

rain. Comal powerplant released daily about 10.5 cfs of pumpage from well in Edwards 

limestone Oct. 1 to Jan. 30, and Aug. 1 to Sept. 30. During the remainder of water 

year, daily releases averaged less than 1 cfs. Comal springs did not flow from Oct. 1 

to about Nov. 3. Flow of river from Oct. 1 to about Nov. 3 consisted of releases from 

powerplant, runoff following local rains, seepage, and flow from small springs in 

vicinity of gage. Comal Springs emerge from the Edwards limestone in the Balcones 

fault zone.

Drainage area. 83.7 sq mi. Normal flow of river comes from springs, drainage area of 

stream not applicable.

Records available. May 1956 to September 1957. June 1915 to January 1916, March 1916 to 

September 1921, and May to September 1956 published as San Marcos River at San Marcos, 

records include some surface runoff. Periodic measurements of spring flow have been 

made at this location since Nov. 14, 1894, and published as miscellaneous measurements.

Gage. Water-stage recorder. Datum of gage is 536.82 ft above mean sea level, datum of 

1929. June 10, 1915, to Jan. 19, 1916, staff gage at site 1.2 miles upstream and 

Mar. 13, 1916, to Sept. 7, 1921, recording gage near present site, datum relations 

unknown.

Extremes. 1956: Maximum daily spring discharge during period May to September, 69 cfs 

May 27, 28; maximum gage height (flood runoff), 5.68 ft Aug. 31; minimum daily spring 

discharge, 46 cfs Aug. 15, 16.

1956-57: Maximum daily spring discharge during water year, 240 cfs Apr. 28 to May 2; 

maximum gage height (backwater from Blanco River), 25.62 ft Apr. 25; minimum daily 

spring discharge, 59 cfs Oct. 3, 4, 17.

Maximum stage known since at least 1913, 38.6 ft, present datum, Sept. 10, 1921 

(backwater from Blanco River).

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

days affected by local runoff, which are fair. Flow slightly regulated by millpond 

just above gage, and by utilities dam about l| miles upstream. Entire flow of river 

from San Marcos Springs, about ij miles upstream, except during periods of local runoff.

278 OUADALUPE RIVER BASIN

San Antonio River at San Antonio, Tex.

Location. Lat 29°24'35", long 98"89 I 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. 48 sq mi, approximately. Normal flow of river formerly came from springs 

but now comes largely from artesian wells; drainage area of stream not applicable.

Records available. January 1915 to November 1929, February 1939 to September 1957.

Ground-water discharge into river is discussed by Petit and George, Texas Board of Water 

Engineers Bulletin 5608, vol. 1 (1956, p. 45).

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. 38 years (1915-29, 1939-57), 57.1 cfs (41,340 acre-ft per year).

Extremes. Maximum discharge during year, 1,850 cfs May 27 (gage height, 9.23 ft), from 

rating curve extended above 580 cfs; minimum daily, 2.1 cfs Feb. 14.

1915-29, 1939-57: 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 because of 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 except those for period of no gage-height record, which are fair. 

Flood flow regulated by Olmos flood-control reservoir (capacity, 15,500 acre-ft) about 

8^ miles upstream. Dam completed in 1986. Normal flow of river formerly came from 

springs located about'8 miles upstream but now comes largely from artesian wella. 

Springs emerged from Edwards limestone in Balcones fault zone. Diurnal fluctuation 

caused by industrial pumping from wells (depleting the underground reservoir) above 

station.

Drainage area. 77.2 sq mi, of which 25.47 sq mi is above 7 flood-detention structures. 

Records available. August 1954 to September 1957.

Gage. Water-stage recorder. Datum of gage is 406.45 ft above mean sea level, datum of 

1929, supplementary adjustment of 1943.

Extremes.--Maximum discharge during year, 5,310 cfs Sept. 25 (gage height, 21.83 ft); no 

flow most of time.

1954-57: Maximum discharge, that of Sept. 25, 1957; no flow most of time. 

Maximum stage known since at least 1860, about 35 ft Sept. 29, 1946, from information by local residents.

Remarks. Records fair. Station operated as part of the Calaveras Creek hydrologic program to evaluate rainfall-runoff relation, soil conservation practices, and the effects 

of flood-detention structures. At the end of the year, the flow from 25.47 sq mi above 

this station was partly controlled by seven flo.odwater detention reservoirs with a 

total combined capacity of 9,570 acre-ft below the flood spillway crests, of which 

8,050 acre-ft is floodwater detention capacity and 1,520 acre-ft is sediment storage 

capacity. One of these reservoirs was constructed during current year and has a capacity below flood spillway crest of 2,450 acre-ft, of which 200 acre-ft is sediment pool 

capacity. The capacity in these reservoirs allocated to sediment storage will be used 

for conservation storage until eliminated by sedimentation.

Location. Lat 28°49', long 97°52', near center of span on downstream side of bridge on 

U. S. Highway 181, in northwest edge of Kenedy, Karnes County, 3-g- miles upstream from 

Dry Escondldo Creek and 85 miles upstream from mouth.

Drainage area. 82.2 sq ml, of which 36.5 sq ml Is above flood-detention structures. 

Records available. July 1954 to September 1957.

~Gage. Water-stage recorder. Datum of gage Is 246.40 ft above mean sea level, datum of 

Extremes. Maximum discharge during year, 2,160 cfs Sept. 23 (gage height, 18.45 ft); no 

flow most of time.

1954-57: Maximum discharge, 3,370 cfs Aug. 31, 1955 (gage height, 19.82 ft); no 

flow most of time.

Maximum stage known since at least 1887, 22.81 ft Aug. 29, 1946, from information by 

local residents.

Remarks. Records good. At end of year flow from 36.5 sq mi above this station was partly 

controlled by 10 floodwater detention reservoirs with a total combined capacity of 

13,870 acre-ft below flood spillway crests, of which 11,340 acre-ft Is floodwater 

detention capacity and 2,520 acre-ft Is sediment storage capacity. Three of these 

reservoirs were constructed during the current year and have a total combined capacity 

of 6,580 acre-ft, of which 589 acre-ft is sediment pool capacity. The capacity in 

these reservoirs allocated to sediment storage will be used for conservation storage 

until eliminated by sedimentation. Station operated as part of the Escondido Creek 

basin hydrologic cooperative program of the Geological Survey and Soil Conservation 

Service to evaluate rainfall-runoff relation, soil conservation practices, and to 

assist the Soil Conservation Service In evaluating the effect of flood-detention structures .

296 NUECES RIVER BASIN

Nueces River near Asherton, Tex.

Location. Lat 28°30', long 99°42!, on right bank just downstream from bridge on Farm to 

Market Road 190 between Asherton and Brundage, 1.2 miles downstream from El Moro Creek, 

5.5 miles northeast of Asherton, Dimmit County, and at mile 288.

Drainage area. 4,082 sq mi.

Records available. October 1939 to September 1957.

Gage.--Water-stage recorder. Datum of gage is 470.92 ft above mean sea level, datum of 

1929. Prior to Feb. 2, 1940, chain gage at same site and datum.

Average discharge. 18 years, 140 cfs (101,400 acre-ft per year).

Extremes. Maximum discharge during year, 7,750 cfs June 2 (gage height, 27.82 ft); no 

flow most of time.

1939-57: Maximum discharge, 24,000 cfs Sept. 2, 1944 (gage height, 30.40 ft); no 

flow at times.

Maximum stage known, about 33 ft June 17, 1935, present site and datum (based on 

relation determined from levels to floodmarks of June 17, 1935, and Sept. 2, 1944, 

floods at farmhouse on left bank 0.8 mile upstream from gage).

NUECES RIVER BASIN 297

Nueces River at Cotulla, Tex.

Location. Lat 28°26', long 99°16', near left bank on downstream side of bridge on U. S. 

Highway 81, at Cotulla, La Salle County, a third of a mile upstream from InternationalGreat Northern Railroad bridge and at mile 236.

Drainage area. 5,260 sq mi.

Records available. July 1915 to June 1918, October 1923 to September 1957. Published as 

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

since 1922, are contained in reports of U. S. Weather Bureau.

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

datum 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, 1984, 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.--34 years (1923-57), 274 cfs (198,400 acre-ft per year).

Extremes. Maximum discharge during year, 12,000 cfs Apr. 22 (gage height, 18.3 ft); no 

flow for many days.

1923-57: 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 good. 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 the 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 U. S. Weather Bureau.

NUECES RIVER BASIN 899

Frio River at Conoan, Tex.

Ion. Lat 29°29', long 99°42', on left bank half a mile southeast of Concan Post 

ce, Uvalde County, and 15 miles upstream from Dry Frio River.

Drainage area. 405 sq mi.

Records available. October 1923 to September 1957.

Gage. Water-stage recorder. Datum of gage is 1,203.71 ft above mean sea level, datum of 

1929. Oct. 26, 1923, to July 28, 1924, staff gage at site 86 ft upstream at datum 

5.08 ft lower. July 29, 1924, to Oct. 31, 1930, combination staff and chain gage and 

Oct. 4, 1930, to May 18, 1939, water-stage recorder, at site 130 ft downstream at 

present datum.

Average discharge.--32 years (1924-29, 1930-57), 92.0 ofs, revised (66,610 acre-ft per 

year).

Extremes. Maximum discharge during year, 13,400 ofs Apr. 24 (gage height, 10.45 ft),

from rating curve extended above 1,300 cfs as explained below; no flow Oct. 1 to Jan. 6.

1923-57: Maximum discharge, 162,000 cfs July 1, 1932 (gage height, 34.44 ft, from 

floodmarks), from rating curve extended above 7,400 cfs on basis of slope-area determinations at gage heights 16.40 and 34.44 ft; no flow Aug. 5, 1956, to Jan. 6, 1957.

Maximum stage known since at least 1869, that of July 1, 1932.

Revisions. The figures of maximum discharge for some water years have been revised, 

as shown in the following table. They supersede figures published in the water-supply 

papers indicated.

Remarks. Records good except those for periods of indefinite stage-discharge relation, 

which are fair, and those for period of no gage-height record, which are poor. Part 

of flow of Frio River enters Edwards limestone in Balcones fault zone which crosses 

basin Just north of Uvalde and below station. Most of low flow enters this formation. 

Many small diversions for irrigation above station.

Extremes. Maximum discharge during year, about 8,000 cfs June 1 (gage height, about 

12.0 ft); no flow Oct. 1 to Dec. 17.

1952-57: Maximum discharge, 23,200 cfs Sept. 24, 1955 (gage height, 18.68 ft, from 

floodmarks), from rating curve extended above 700 cfs on basis of slope-area determinations at gage heights 14.12 and 26.0 ft (made at site 2.6 miles upstream); no flow at 

times.

Flood of June 14, 1935, reached a stage of 26.0 ft, from information by local resident (discharge at site 2.6 miles upstream, 64,700 cfs, by slope-area determination of 

peak flow).

Remarks. Records fair. Part of flow of Dry Frio River enters Edwards limestone in Balcones fault zone which crosses basin just north of Uvalde and below station. Most of 

low flow enters this formation. Small diversions above station.

NUECES RIVER BASIN 313

Nueces River near Three Rivers, Tex.

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

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

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

Drainage area. 15,600 sq mi.

Records available. July 1915 to September 1957. 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. 40 years (1915-18, 1920-57), 780 cfs (564,700 acre-ft per year).

Extremes.--Maximum discharge during year, 22 200 cfs May 3 (gage height, 39.20 ft); minimum, 1.0 cfs Oct. 6 (gage height, 1.24 ft).

1915-57: 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 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 8.5 cfs was discharged from 

several artesian wells into the Atascosa River upstream from this station to supplement 

the supply for the city of Corpus Christ!.

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

314 NUECES RIVER BASIN

Lake Corpus Christi near Mathis, Tex.

Location. Lat 28°02'52", long 97°52'16", 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 Patriclo County, and at mile 48.

Drainage area. 16,656 sq mi.

Records available. September 1948 to September 1957. 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.

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

aatum 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, 56,320 acre-ft Sept. 29 (gage height, 

76.88 ft); minimum observed, 17,950 acre-ft Sept. 21, 22 (gage height. 68.40 ft).

1948-57: 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 five 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 Christi. 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. Gage-height record furnished by city of Corpus Christi.

T929. Prior to May 16, 1908, staff gage at site 4 miles downstream at different datum. 

May 16, 1908, to Nov. 8, 1910, staff or chain gage on bridge at present site and datum.

Average discharge. 68 years (1889-1957), 930 cfs (673,300 acre-ft per year).

Extremes. Maximum discharge during year, 7,120 cfs July 27 (gage height, 5.24 ft); minimum daily, 74 cfs Nov. 16.

1889-1957: Maximum discharge, 18,000 cfs Oct. 5, 1911 (gage height, 6.80 ft), from 

rating curve extended above 6,000 cfs; minimum daily, 69 cfs Aug. 21, 1902.

Remarks. Records excellent except those for periods of ice effect or no gage-height 

record, which are fair. Discharge measurements generally made twice a month. Small 

diversions above station for irrigation. Flow regulated by three main reservoirs 

(total capacity, 122,900 acre-ft) and several smaller ones. Transmountain diversions 

to drainage area above station from Colorado River basin (see p. 331).

Extremes. Maximum discharge during year, 2,920 cfs June 10 and July 9; maximum gage 

height, 4.83 ft June 10; minimum daily discharge, 12 cfs Jan. 30.

1899-1900, 1903-57: Maximum discharge, 9,000 cfs Oct. 5, 1911 (gage height, 8.50 ft, 

from floodmarks, present site and datum), from rating curve extended above 3,000 cfs; 

minimum daily, that of Jan. 30, 1957.

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

wETch are fair, and those for period of indefinite stage-discharge relation, which are 

poor. Discharge measurements generally made three times a month. Diversions for irrigation of about 500 acres of hay meadows above station. Some regulation by Platoro 

Reservoir (see p. 339).

1914-20, 1924-57: Maximum discharge, 3,160 cfs May 12, 1941 (gage height, 5.77 ft, 

site and datum then in use), from rating curve extended above 1,600 cfs; minimum 

observed, 4.0 cfs Dec. 17, 1945 (discharge measurement), but may have been less during 

period of no gage-height record.

Remarks. Records good above 200 cfs and fair below 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.

RIO GRANDE BASIN 

Rio Grande de Ranches and Rio Chiquito seepage investigation

371

On July 16, 1957, a seepage study was made along Rio Grande de Ranches and its tributary Rio Chiquito in the general vicinity of Taos, N. Mex. Purpose of the investigation 

was to determine seepage gains or losses in the various reaches of the two streams. All 

known net diversions were measured, plus Arroyo Miranda, and concentrated wasteways as 

indicated in tabulation. Scattered surface waste from the many irrigated fields was not 

measured. There was no precipitation and streamflow conditions were relatively stable. 

For daily-discharge figures at regular gaging stations on Rio Pueblo de Taos (stream to 

which Rio Grande de Ranches is tributary), see index; for results of July 16 measurements 

of tributaries or distributaries to Rio Pueblo de Taos, see "Discharge measurements made 

at points other than gaging stations" (p. 522).

Revisions (water years) . WSP 358: 1900-1902. WSP 878: 1915-16. Figures of daily discharge as published in WSP 358 for Oct. 4 to Nov. 30, 1896, are considered to be in 

error owing to absence of sufficient and reliable gage-height data. Revised figures of 

discharge, in cubic feet per second, for the water years 1892-99, 1904, 1916, 1931-32, 

1939, 1944-45, and 1950, superseding figures published in WSP 358, 733, 878, 1008, 1038,

Average discharge. 44 years (1912-17, 1918-57), 604 cfs (437,300 acre-ft per year).

Extremes. 1912-13: Maximum gage height during water year, 4.95 ft June 11 (discharge not 

determined); minimum daily discharge not determined.

1956-57: Maximum discharge during water year, 4,280 cfs Aug. 7 (gage height, 

5.13 ft); minimum daily, 0.4 cfs Oct. 12, 13.

1930-57: Maximum discharge, 9,910 cfs May 14, 1941; no flow at times.

Revisions . Figures of maximum discharge for the water years 1929 and 1934 have been 

revised to 10,000 cfs Aug. 12, 1929 (gage height, 7.4 ft, from hydrographer's notes) 

and 1,600 cfs Apr. 13, 1934 (gage height, 3.33 ft), superseding figures published in 

WSP 842 and 763, respectively.

Remarks. Records fair November 1912 to September 1913 except those for periods of ice 

eTTect and doubtful or no gage-height record, which are poor. Records good for water 

year 1957 except those for periods of ic& effect, which are poor. Discharge measurements generally made 3 or 4 times a month. Diversions above station for irrigation of 

about 30,000 acres, a few hundred of which are below station. Plow partly regulated by 

El Vado Reservoir (see p. 483) 77 miles upstream. Records of water temperatures and 

suspended sediment loads for the water year 1957 are given in WSP 1522.

Revisions. Revised figures of discharge, in cubic feet per second, for the water years

 1913-15, 1934, and 1936, superseding those published in WSP 358, 388, 408, 763, and

808, are given herewith. Complete table of daily discharges is given for the water year

Rio Santa Cruz above Chimayo in 1930-31) in reports of State engineer.

Gage. Water-stage recorder. Concrete control since Jan. 3, 1954. Altitude of gage is 

b,460 ft (from topographic map). Prior to January 1930, staff gage at approximately 

same site at different datum. Sept. 1, 1930, to Aug. 12, 1932, water-stage recorder 

at site about 1 mile downstream at different datum. Aug. 13, 1932, to Oct. 29, 1934, 

water-stage recorder at site 35 ft upstream at datum 0.42 ft higher. Oct. 30, 1934, 

to Jan. 2, 1954, at datum 0.64 ft lower.

Average discharge . 41 years (1915-29, 1930-57), 31.7 cfs (22,950 acre-ft per year).

Extremes.--Maximum discharge during year, 152 cfs June 10 (gage height, 2.55 ft); minimum 

daily determined, 2.6 cfs Oct. 2, 9.

1931-57: Maximum discharge, 2,420 cfs Sept. 24, 1931 (gage height, 7.8 ft), from 

rating curve extended above 170 cfs by logarithmic plotting; minimum daily, 1.1 cfs 

Dec. 3, 1950.

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

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

c Published figure is not reliable and should not be used.

d Occurred sometime Oct. 6-8, 1911.

e From recorded range in stage.

1898-99, 1904-5, 1930-57: Maximum discharge determined, 22,500 cfs May 16, 1941; 

maximum gage height, 13.70 ft May 14, 1941; minimum daily discharge, 62 cfs July 12-14, 

1904.

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

Discharge measurements generally made four times a month. Flow partly regulated by 

El Vado Reservoir (see p, 483) 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 suspended sediment loads for the water year 1957 are given in WSP 1522.

Revisions. Revised figures of discharge, in cubic feet per second, for the water years 

1895-99, 1904-6, 1911-12, 1914, 1935, superseding those published in WSP 358, 388, and 

788 are given herein. Complete tables of daily discharge are given for the water years 

1898-99 and 1904-5, but only revised discharges are given for other water years.

Location. Lat 35°23'10", long 106°31'45", in NE£ sec. 5, T. 13 N., R. 4 E., on right bank 

three-quarters of a mile downstream from Jemez Canyon Dam, If miles upstream from mouth, 

and 6 miles north of Bernalillo.

Drainage area. 1,040 sq mi, approximately.

Records available.--March 1936 to January 1938, March 1943 to September 1957. Prior to 

October 1953, published as "near Bernalillo."

Gage.--Water-stage recorder. Datum of gage is 5,100.00 ft above mean sea level, datum of 

T929 (Corps of Engineers benchmark). Prior to Apr. 24, 1951, at site three-quarters of 

a mile upstream at datum 20.11 ft higher. Supplementary water-stage recorder at gates 

of Jemez Canyon Dam at datum 5,125.00 ft above mean sea level, datum of 1929 (Corps of 

Engineers benchmark) used at times since January 1953.

Average discharge.--15 years (1936-37, 1943-57), 44.1 cfs (31,930 acre-ft per year).

Extremes. Maximum discharge during year, 704 cfs May 9 (gage height, 8.52 ft); no flow at 

times.

1936-38, 1943-57: Maximum discharge, 16,300 cfs (revised) Aug. 29, 1943 (gage 

height, 5.62 ft, site and datum then In use), from rating curve extended above 3,000 

cfs by logarithmic plotting; no flow at times.

Revisions. The figures of maximum discharge for some water years have been revised, 

as shown In the following table. They supersede figures published In the water-supply 

papers indicated.

Remarks. Records poor. Discharge measurements generally made eight times a month when 

flow Is sufficient. Subsequent to October 1953. flow at this station can be completely 

regulated by Jemez Canyon Reservoir (see p. 483). 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 1957, are given in WSP 1522.

overflow; since that date, entire flow Is Included.

Gage. Water-stage recorder. There are 3 gages, 1 on a conveyance channel designed to 

carry 2,000 cfs, 5 miles downstream from heading, formerly San Francisco riverside 

drain, 1 on the floodway (former river channel which will now carry water when total 

flow exceeds about 1,700 cfs), and 1 on Bernardo Interior drain. Datum of conveyance 

channel gage Is 4,719.23 ft above mean sea level, adjustment of 1951. Prior to October 1952, main gage was on river channel (the present floodway gage) at datum 4,722.55 

ft above mean sea level, adjustment of 1951. Datum of Bernardo Interior drain supplementary recording gage Is 4,713.99 ft above mean sea level, datum of 1929, 1951 adjustment.

Average discharge . 17 years (1936-38, 1941-42, 1943-57), 1,124 cfs (813,700 acre-ft per 

year).

Extremes. Maximum dally discharge during year, 6,220 cfs Aug. 31; no flow Oct. 1-24. 

TS36-39, 1941-42, 1943-57: Maximum discharge not determined, probably occurred 

Apr. 25, 1942; maximum dally, 19,600 cfs Apr. 25, 1942; no flow at times.

Remarks. Records fair. Records represent total discharge of the river, and are a suramation of discharge In river channel (now called floodway), conveyance channel, and 

Bernardo Interior drain, but do not Include flow In a drain (gaged since July 1954) 

and a small canal on left side of floodway. Diversions for Irrigation of about 740,000 

acres abo/e station. Records of chemical analyses, water temperatures, and sediment 

loads for the water year 1957 are given In WSP 1522.

Discharge, in cubic feet per second, water year October 1956 to September 1957

RIO GRANDE BASIN 415

Bluewater Creek near Bluewater, N. Mex.

Location. Lat 35°17'50", long 108"01'40", In W^SWi sec. 5, T. 12 N., R. 11 W., on left

 bank 3| miles (revised) northwest of Bluewater Village and 8 miles downstream from Bluewater Dam.

Drainage area. 235 sq mi. 

Records available.--July 1912 (corrected) to December 1914 and October 1930 to September

 1957 In reports of Geological Survey. July 1912 to June 1919 and April 1921 to December 1931 in reports of State engineer. 

Gage (revised).--Water-stage recorder. Altitude of gage is 6,720 ft (by barometer). Prior

 to Mar. 4, 1918, at site 113 ft upstream at different datums. Mar. 4, 1918, to Mar. 17, 

1939, at site 83 ft upstream; Mar. 4, 1918, to June 28, 1919 (destroyed by flood) at 

datum 1.92 ft higher, Apr. 6, 1921, to Mar. 17, 1939, at datum 1.57 ft higher.

Average discharge . 29 years (1912-14, 1930-57), 10.6 cfs (7,670 acre-ft per year).

Extremes.--1913-14: Maximum discharge recorded during water year, 347 cfs July 26 (gage

 height, 4.7 ft); no flow at times.

1956-57: Maximum discharge during water year, 524 cfs July 26 (gage height, 5.48 ft); 

no flow at times. ,

1912-14, 1930-57: Maximum discharge, 1,210 cfs July 23, 1954 (gage height, 7.28 ft); 

no flow at times.

Revisions.--The maximum discharge for the water year 1945 has been revised to 136 cfs 

Aug 19, 1945 (gage height, 3.96 ft) and date of the maximum discharge for the water 

year 1943 is corrected to Aug. 28, 1943, superseding figures published in WSP 978 and 

1038. The figure of maximum discharge for July 22, 1912, published in WSP 408, has been 

found to be unreliable and should not be used. 

Remarks. Records fair except those for periods of ice effect, which are poor. Discharge

 measurements generally made twice a month. Flow regulated by Bluewater Lake (capacity

46,000 acre-ft). 

Revisions --Revised figures of discharge, in cubic feet per second, for the water years

 1912-15, and 1931, superseding those published in WSP 358, 388, 408, and 733, are given 

herein. Complete table of daily discharges are given for the water year 1914, but only 

revised discharges are given for other water years. Figures of daily discharge for 

July 20-23, 1912, published in WSP 358 have been found to be unreliable and should not 

be used.

Drainage area. l, OOP sq ml, approximately.

Records available . October to December 1912 (fragmentary), January 1913 to September 1914 

(gage heights and discharge measurements only March to May, July to September 1914), 

and April 1949 to September 1957 in reports of Geological Survey. October 1912 to 

December 1926 (monthly figures only for calendar year 1925) in reports of State engineer.

Gage. Water-stage recorder. Datum of gage is 6,468.34 ft above mean sea level (levels 

by Corps of Engineers). Oct. 30, 1912, to Apr. 23, 1915, staff gage, Apr. 24, 1915, 

to Dec. 5, 1917, chain gage, and Dec. 6, 1917, to Dec. 31, 1926, staff gage, at nearby 

sites at different datums.

Average discharge . 19 years (1914-25, 1949-57), 6.33 cfs (4,580 acre-ft per year).

Extremes . --Maximum discharge during year, 685 cfs Aug. 29 (gage height, 4.59 ft); no flow 

for long periods.

1912-26, 1949-57: 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 fair except those for periods of no gage-height record, which are poor. 

Discharge measurements generally made twice a month. Flow regulated by Bluewater Lake 

(capacity, 46,000 acre-ft, original survey). Diversions and ground-water withdrawals 

for irrigation of about 4,500 acres above station.

Revisions. WSP 1212: Drainage area. Revised figures of discharge, in cubic feet per 

second, for the water years 1913-14, superseding those published in WSP 358 and 388,

Location. Lat 34°58'00", long 107 010'10", in NE£ sec. 32, T. 9 N., R. 3 W., on left bank 

0.6 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 1957. Prior to October J.955, published as San 

Jose River at Correo.

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

sea level, unadjusted.

Average discharge. 14 years, 13.3 cfs (9,630 acre-ft per year).

Extremes. Maximum discharge during year, 4,910 cfs July 26 (gage height, 9.37 ft); no 

flow for much of year.

1943-57: Maximum discharge, 7,150 cfs Aug. 11, 1955 (gage height, 11.1 ft); 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 fair except those for periods of no gage-height repord, which are poor. 

Discharge measurements generally made three times a month. Flow partly regulated by 

Bluewater Lake (capacity, 46,000 aere-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).

420 RIO GRANDE BASIN 

Rio Puerco at Rio Puerco, N. Mex.

Location. Lat 34°47'35", long 106°59'20", in NW£ sec. 31, T. 7 N., R. 1 W., in San 

Clemente Grant, on downstream end of pier nearest left abutment of Atchison, Topeka 

and Santa Fe Railway bridge, 7 miles downstream from San Jose River.

Drainage area. 5,160 sq mi, approximately.

Records available. September 1910 to December 1912 (records fragmentary, gage heights 

only), March 1934 to September 1957 in reports of Geological Survey. January 1915 to 

December 1925, September 1926 to December 1927 in reports of State engineer. Records 

for January 1913 to December 1914, published in WSP 358, 388, and 408, have been found 

to be unreliable and should not be used.

gage. Water-stage recorder and concrete control. Datum of gage is 5,008.49 ft above 

mean sea level, datum of 1929.

Average discharge. 30 years (1915-17, 1919-20, 1921-24, 1926-27, 1934-57), 71.6 cfs 

(51,840 acre-ft per year).

Extremes. Maximum discharge during year, 7,480 cfs Aug. 25 (gage height, 4.64 ft); no 

flow at times..

1934-57: Maximum discharge, 28,000 cfs Aug. 21, 1935 (gage height, 7.24 ft), by 

computation of peak flow over dam; no flow at times.

Flood of Sept. 23, 1929, indicated a discharge of approximately 40,000 cfs. A 

higher discharge possibly occurred Oct. 4, 1913, at a recorded stage of about 9.7 ft.

Remarks. Records fair except those for periods of no gage-height record and those below 

5 cfs, which are poor. Discharge measurements generally made four times a month, but 

more often during high-flow and less during low-flow periods. Diversions for irrigation 

of about 12,300 acres above station (includes 4,500 acres irrigated wholly or partly 

from wells).

Rev is ions.--Rev is ed figures of discharge, in cubic feet per second, for the water years 

1941 and 1944, superseding those published in WSP 928 and 1008, are given herewith:

Drainage area.--5,860 sq mi, approximately.

Records available.--September 1910 to August 1914 (published as "near La Joya", discharge 

measurements only), November 1939 to September 1957. Fragmentary gage-height record 

and footnotes concerning no flow, for the period September 1910 to August 1914 published 

in WSP 358 and 388, have been found to be in error and should not be used.

Gage. Water-stage recorder. Datum of gage is 4,725.44 ft above mean sea level, 1951 adjustment. September 1910 to August 1914, at site 1-| miles downstream at different 

datum.

Average discharge. 17 years (1940-57), 59.8 cfs (43,290 acre-ft per year).

Extremes.--Maximum discharge during year, 5,680 cfs Aug. 7 (gage height, 11.25 ft); no flow 

for extended periods.

1939-57: Maximum discharge, 18,800 cfs Sept. 23, 1941, from rating curve extended 

above 7,800 cfs by logarithmic plotting; maximum gage height, 13.8 ft Aug. 12, 1955; no 

flow for extended periods.

1929.

Average discharge.--10 years, 14.5 cfs (10,500 acre-ft per year).

Extremes.--Maximum discharge during year, 7,100 cfs Aug. 24 (gage height, 12.15 ft), from 

rating curve extended above 2,000 cfs by logarithmic plotting; no flow for long periods. 

1947-57: Maximum discharge, 16,600 cfs Sept. 25, 1954 (gage height, 12.80 ft), from 

rating curve extended above 2,000 cfs by logarithmic plotting; no flow for long periods. 

Revisions. Figures of maximum discharge for the water years 1948 and 1949 have been 

revised to 1,830 cfs Sept. 26, 1948 (gage height, 10.7 ft) and 4,050 cfs July 13, 1949 

(gage height, 11.19 ft), superseding figures published in WSP 1118 and 1148, respectively.

Remarks.--Records poor. Discharge measurements made frequently during known periods of 

flow. Diversions for irrigation of about 100 acres above station. Records of water 

temperatures and sediment loads for the water year 1957 are given in WSP 1522.

Revisions. Revised figures of discharge, in cubic feet per second, for the water years 

1948-49, and 1955, superseding those published in WSP 1118, 1148, and 1392, are given

RIO GRANDE BASIN 431

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

Location. Lat 33°44', long 106°55', in sec. 36, T. 63., 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 June 1957 (discontinued). Prior to October 1955, 

published as Conveyance channel (Rio Grande) below heading, near San Marcial.

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 period, 1,450 cfs June 28; minimum daily, 

" °2~9 cfs Oct 1

1953-57:' Maximum discharge, 1,670 cfs Sept. 28, 1954 (gage height, 5.42 ft); no 

flow at times.

Remarks.--Records fair. Discharge measurements generally made twice a week. 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 earthern 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. 433). Daily discharge 

computed by subtracting daily mean discharge of San Antonio Riverside 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). Records of water 

temperatures and sediment loads for the water year 1956 are given in WSP 1522.

432 RIO GRANDE BASIN

Rio Grande at San Marcial, N. Mex.

Location. Lat 33°40'50", long 106°59'15", in Pedro Armendaris Grant 33, on pier of Atchison, Topeka and Santa Fe Railway bridge, 1.1 miles downstream from former site of San 

Marcial, Socorro County, and 18J miles southwest of San Antonio.

Drainage area.--27.700 sq mi, approximately (includes 2,940 sq mi in closed basin in San 

Luis Valley, Colo. ).

Records available.--January 1895 to September 1957 in reports of Geological Survey. January 1931 to September 1949 in Water Bulletins of International Boundary Commission.

RIO GRANDE BASIN 433

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, 25 miles northeast of Truth or Consequences (formerly Hot Springs) Sierra 

County.

Records available. December 1953 to June 1957 (discontinued). Prior to October 1954, 

published as Conveyance channel at mouth of Nogal Canyon, near Truth of Consequences .

Gage.--Water-stage recorder. Datum of gage is 4,402.20 ft above mean sea level, datum of 

1929 (levels by Bureau of Reclamation). Prior to October 1955, at datum 3.00 ft 

higher.

Extremes.--Maximum discharge during period, 1,610 cfs June 29; maximum gage height, 6.86ft 

May 15; minimum daily, 10 cfs Oct. 20-25.

1954-57: Maximum discharge, 1,770 cfs July 29, 1955; maximum gage height, that of 

May 15, 1957; minimum daily, 9 cfs Sept. 29, 1956.

Remarks. Records good. Measurements made 5 to 10 times a month. When there is no flow 

in the floodway channel, the entire Rio Grande flow passes this station. 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 earthern 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.

RIO GRANDE BASIN 441 

Gallinas River at Montezuma, N. Mex.

Location. Lat 35°39'15", long 105°16'30", in Las Vegas Grant, near center of span on 

downstream side of highway bridge, half a mile downstream from Montezuma, San Miguel 

County, and 5 miles northwest of Las Vegas.

Drainage area. 87 sq mi, approximately.

Records available. August 1903 to December 1914 (prior to October 1904, gage heights only) 

and October 1930 to September 1957 in reports of Geological Survey. October 1904 to 

December 1931 in reports of State engineer (prior to 1930, published as "near Las Vegas").

Gage. Water-stage recorder. Altitude of gage is 6,675 ft (from topographic map). Prior 

to Mar. 24, 1926, staff gage at same site and datum.

Average discharge. 50 years (1905-11, 1913-57), 19.0 cfs (13,760 acre-ft per year).

Extremes. Maximum discharge during year, 9,140 cfs Aug. 4 (gage height, 11.8 ft, from 

floodmarks), from rating curve extended above 450 cfs on basis of slope-area determination of peak flow; no flow for several days.

1930-57: Maximum discharge, that of Aug. 4, 1957; no flow Oct. 4-9, 1934, July 27- 

29, 1956, several days in 1956-57.

A very destructive flood, probably the greatest known, occurred Sept. 29, 30, 1904.

Remarks. Records good above 1 cfs and fair below, except those for period of no gageheight record, which are fair. Plow partly regulated at low flows by small reservoirs 

owned by Public Service Co. of New Mexico. Diversions for irrigation of about 15 acres 

above station and for Las Vegas city water supply.

Revisions (water years). WSP 1178: 1942.

Average discharge. 21 years (1913-16, 1918-25, 1926-37), 264 cfs (prior to completion of 

Alamogordo Dam). 20 years (1937-57), 224 cfs (162,200 acre-ft per year).

Extremes. Maximum daily discharge during year, 1,380 cfs Sept. 18-21 (gage height, 

3.30 ft); no flow for several days.

1930-57: Maximum discharge, 42,800 cfs Sept. 1, 1942, by computation of flow over 

spillway and through outlet gates of Alamogordo Dam by Bureau of Reclamation; maximum 

gage height, 13.58 ft Sept. 22, 1941, from floodmark; no flow at times.

Remarks. Records good. Discharge measurements generally made two or more times a month. 

Diversion for irrigation of about 17,500 acres above station. Flow regulated by Alamogordo Reservoir [see p. 484). Records of chemical analyses for the water year 1957 

are given in WSP 1522.

Revisions. Revised figures of discharge, in cubic feet per second, for the water year 

1932, superseding those published in WSP 733, are given herewith:

456 RIO GRANDE BASIN

Cottonwood Creek near Lake Arthur, N. Mex.

Location. Lat 32°55'00", long 104 t> 22'00", in SW£SE± sec. 15, T. 16 S., R. 26 E. , on right 

bank l| miles upstream from mouth and 6 miles south of town of Lake Arthur.

Drainage area. 199 sq mi (contributing area).

Records available (revised) . March 1932 to September 1957. All figures of discharge above 

150 cfs prior to June 1937; daily discharges Sept. 24-30, 1932, June 13, 14, Sept. 5, 

1935, and May 29, 1937, are unreliable and should not be used.

Gage (revised). Water-stage recorder and concrete control. Datum of gage is 3,316.3 ft 

above mean sea level (river-profile survey). Prior to Aug. 30, 1938, at site 75 ft 

downstream at different datum prior to Mar. 29, 1935; at datum 1.36 ft lower Mar. 29, 

1935, to Sept. 30, 1936, and at datum 2.10 ft lower Oct. 1, 1936, to Aug. 29, 1938. 

Aug. 30, 1938, to May 22, 1948, at present site at datum 1.54 ft lower.

Average discharge (revised) . 23 years (1932-34, 1935-36, 1937-57), 7.09 cfs (5,130 acre-ft 

per year).

Extremes. Maximum discharge during year, 38 cfs June 1 (gage height, 4.11 ft); minimum 

daily, 0.1 cfs for many days.

1932-57: Maximum discharge uncertain, occurred June 13, 1935 (previously published 

figure is in error); maximum gage height, 12.0 ft May 30, 1937, present datum, from 

floodmarks (backwater from Pecos River); no flow at times.

Revisions. The maximum discharges for the water years 1932 , 1935, 1937, published in 

WSP 733, 788, 828, and 842, are considered to be in error, owing to absence of sufficient data to extend the rating curves and should not be used. Date of maximum discharge of 1941 occurred on May 23 instead of May 24. The maximum discharge for the 

water year 1944 has been revised to 60 cfs June 29, 1944 (gage height, 4.67 ft), superseding figure published in WSP 1008.

Remarks. Records good. Discharge measurements made twice a month. Diversions above 

station for irrigation of about 4,500 acres.

Revisions..--Figures of daily discharge for Sept. 24-30, 1932, June 13, 14, Sept. 5, 1935, 

May 29, 1937, and figures of daily discharge above 150 cfs prior to June 1937 are considered to be in error owing to absence of sufficient data to extend the high-water 

rating curves and conclusive comparisons. These records should not be used. See also 

Records available. Figure of acre-feet published in WSP 763 for October 1933 is in 

error and should be 507 instead of 307.

Peak discharge (base, 20 cfs, revised). June 1 (8 a.m.) 38 cfs (4.11 ft).

Note.--Ho gage-height record Aug. 27 to Sept. 19, Sept. 28-30; discharge estimated on basis of 

trend of flow and recorded range In stage.
RIO GRANDE BASIN 457 

Pecos River near Artesia, N. Mex.

Location. Lat 32°50'25" (revised), long 104°19'25", in NW^NW^ 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)

,^f- fvallable (revised). September 1905 to September 1925 and October 1931 to February 

19d6 (published as near Dayton ), February to September 1936 and May 1937 to September 

1957 in reports of Geological Survey. Records from March to August 1905, are not equivalent due to tributary inflow. Records for Aug. 22-31, 1934 (monthly figure usable? and 

October 1936 to April 1937, published in WSP 763 and 828 respectively, have been found 

unreliable and should not be used. September 1905 to December 1931 in report of State 

engineer.

Gage.--Water-stage recorder. Datum 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 §\ miles downstream at different datum. Feb. 21, 1936, to Apr. 4, 

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

Average discharge.--20 years 1937-57), 318 cfs (230,200 acre-ft per year).

Extremes.--Maximum discharge during year, 3,640 cfs May 31 (gage height, 12.33 ft); no 

flow July 4-10.

1905-57: Maximum gage height, 17.4 ft Sept. 30, 1932 (previously published maximum 

gage height not the maximum), site and datum then in use (discharge not determined). 

Flood of May 30, 1937, reached a gage height of 14.7 ft, site and datum then in use 

(discharge, 51,500 cfs, by slope-area determination of peak flow about 15 miles upstream); flood of Sept. 25, 1941, reached a gage height of 13.32 ft, present site and 

datum (discharge may have equaled that of May 30, 1937); no flow at times in 1934, 1946- 

47, 1953-54, 1957.

Revisions. Figures of maximum discharge for the water years 1917 and 1918 have been 

revised to 6,220 cfs Aug. 20, 1917 (gage height, 10.50 ft) and 6,270 cfs Aug. 10, 1918 

(gage height, 10.87 ft), superseding figures published in WSP 458 and 478, respectively.

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

Discharge measurements generally made two or more times a month. Flow partly regulated 

by Alamogordo Reservoir (see p. 484). Diversions and ground-water withdrawals for irrigation of about 128,000 acres above station. Discharge represents inflow to Lake 

McMillan, which stores water for irrigation of about 25,000 acres of Carlsbad project.

Revisions (water years) . Revised figures of discharge, in cubic feet per second, for the 

water years 1913, 1915, 1920, 1923, and 1932-36, superseding figures published in 

WSP 358, 408, 508, 568, 763, 788, and 808 are given herewith. Figures of daily discharge Aug. 22-31, 1934, and October 1936 to April 1937, published in WSP 763 and 828 

have been found to be unreliable and should not be used. See also Records available.

Pecos River seepage investigation

During the water year 1957, four series of discharge measurements were made on the 

Pecos River and tributaries in New Mexico between the gaging stations "near Acme" and 

"near Artesia" to determine gains or losses. Figures of gains or losses in table below 

are for individual reaches between measuring sites on mainstream. The series of measurements were made Oct. 17, Jan. 2, Mar. 4, and June 19, at times when streamflow was nearly 

constant and unaffected by any recent precipitation or other climatalogical factors. Measurements were made of all diversions from and tributaries to the Pecos River in the reach. 

Tributaries or diversions not listed were dry. Some measurements were made and furnished 

by engineers from the office of the New Mexico State Engineer.

Similar series of discharge measurements were made in 1955 and 1956 and published as 

"Pecos River seepage investigation." Prior to 1955, they were listed under "Miscellaneous 

discharge measurements" and are available on request to the district office in Santa Pe, 

N. Mex.

In addition, records of chemical analyses are published in water-supply papers, "Quality of Surface Waters of the United States."

"Reclamation benchmark). Prior to Mar. 23, 1955, at site 3 miles downstream at datum 

9.83 ft lower.

Average discharge. 7 years, 138 cfs (99,910 acre-ft per year).

Extremes. --Maximum daily discharge during year, 1,110 cfs Aug. 2 (maximum gage height, 

5.72 ft June 1 ) ; no flow June 27 to July 10, Sept. 8-20.

1950-57: Maximum daily discharge, 2,600 cfs Oct. 10, 1954; no flow at times in 

1951-54, 1956-57.

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

Discharge measurements made two or more times a month. Flow partly regulated by 

Alamogordo Reservoir (see p. 484). Diversions and ground-water withdrawals above 

station irrigate about 147,000 acres. Above about 1,500 cfs flow will begin bypassing 

station and, depending on magnitude and duration of flow, may reach Lake McMillan.

478 RIO GRANDE BASIN

Phantom Lake Spring near Toyahvale, Tex.

Location. Lat 30°56', long 103°51', on left bank of outlet canal 375 ft below source of 

spring, 4.0 miles southwest of Toyahvale, Reeves County, and 8.0 miles southwest of 

Balmorhea.

Records available. December 1931 to December 1933, October 1948 to September 1957.

Gage. Water-stage recorder and Parshall flume. Datum of gage is 3,472.69 ft above mean 

 sea level (Bureau of Reclamation benchmark). Dec. 21, 1931, to Dec. 31, 1933, waterstage recorder at site 425 ft downstream at datum 3.05 ft higher.

Average discharge. 10 years (1932-33, 1948-57), 14.3 cfs (10,350 acre-ft per year).

Extremes.--Maximum daily discharge during year, 12 cfs at times; minimum daily, 10 cfs 

Jan. 5 to Feb. 28, Sept. 5-16.

1931-33, 1948-57: Maximum daily discharge, 114 cfs Oct. 2, 3, 1932; minimum daily, 

that of Jan. 5 to Feb. 28, Sept. 5-16, 1957.

Remarks. Records good. Discharge represents total flow of spring. Spring flow fluctuates slowly; check gates below gage affect stage-discharge relation frequently; daily 

discharge determined from hydrograph based on discharge measurements. Water used for 

irrigation in vicinity of Toyahvale and Balmorhea. Record low flow measured on Jan. 5 

to Feb. 28, and Sept. 5-16, 1957, probably represents direct effect of the drought. 

There has been no significant development of ground water from wells in the vicinity of 

the spring and the low flow appears to be the result of reduction of recharge to the 

contributing ground-water reservoir during the present drought.

RIO GRANDE BASIN 479

San Solomon Springs at Toyahvale, Tex.

Location. Lat 30°56', long 103"47', on left bank of South Canal at Toyahvale, Reeves 

County, 540 ft downstream from spring pool.

Records available.--October 1931 to December 1933, March 1941 to September 1957.

Gage.--Water-stage recorder and sharp-crested weir. Datum of gage is 3,311.02 ft above 

mean sea level, datura of 1929. Prior to Nov. 18, 1931, at site about 0.6 mile downstream.

Average discharge.--18 years (1931-33, 1941-57), 35.0 cfs (25,340 acre-ft per year).

Extremes. Maximum daily discharge during year, 33 cfs Aug. 2; minimum daily, 27 cfs 

Jan. 1-31.

1931-33, 1941-57: Maximum daily discharge, 71 cfs Oct. 7-9, 1932, Oct. 26-30, 1941; 

minimum daily, 27 cfs Jan. 1-31, 1957.

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

Discharge represents total flow of springs and is determined by combining flows in 

South Canal and two additional outlets (flow measured periodically), Middle and North 

Canals. Flow into each canal regulated by operation of headgates. Water used for 

irrigation in vicinity of Balmorhea. There has been no significant development of 

ground water from wells in the vicinity of the spring and the low flow appears to be 

the result of reduction of recharge to the contributing ground-water reservoir during 

the present drought.

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 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 481

Comanohe Springs at Fort Stookton, Tex.

Location. Lat 30°53', long 102°52 I , 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 availableT February 1941 to September 1957.

Gage. Water-stage recorder and concrete control. Datum of gage is 2,922.82 ft above mean 

sea level, datum of 1929.

Average discharge. 16 years, 31.2 cfs (22,590 acre-ft per year).

Extremes.--Maximum daily discharge during year, 20 cfs Feb. 25 to Mar. 7; no flow for many 

Says.

1941-57: Maximum daily discharge, 56 cfs June 4, 1955 (affected by surface water 

released from flood-control reservoir); no flow at times in 1955, 1956, and 1957.

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

withdrawal 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. During 

periods Oct. 19-22, Feb. 7-11, May 18, 19, 31, June 1-11, Sept. 11, 12, a total of 

320 acre-ft of water was released from reservoir above springs and flowed past the gage 

and is not included in records given herein. Water used to irrigate about 6,000 acres 

of land below the station.

San Vicente Arroyo at Silver City, N. Mex.

Location. Lat 32°46'15", long 108°16'30", in NWiSE^ sec. 3, T. 18 S., R. 14 W. (proJected) , on left bank in Silver City, just upstream from Bullard Street, about 300 ft 

upstream from bridge at Broadway Street and about 1 ,800 ft downstream from confluence 

of Silva Creek and Pinos Altos Creek.

Drainage area. 26.5 sq mi.

Records available. --August 1953 to September 1957.

Gage. Water-stage recorder. Altitude of gage is 5,845 ft (from topographic map).

Extremes . --Maximum discharge during year, 2,920 cfs Aug. 30 (gage height, 8.53 ft), by 

slope-conveyance method; no flow most of time.

1953-57: Maximum discharge, that of Aug. 30, 1957; no flow for many days each year.

A destructive flood (discharge probably exceeded 10,000 cfs) occurred July 12, 1895, 

and began the erosion of Main Street to create the channel currently known as San 

Vicente Arroyo.

Remarks . Records fair except those for period of indefinite stage -discharge relation, 

which are poor. Discharge measurements or observations of no flow generally made 2 or 

3 times a month and more often during periods of flow.

Discharge, in cubic feet per second, water year October 1956 to September 1957

and 5.5 miles upstream from mouth.

Drainage area.--180 sq mi (revised), approximately.

Records available. April 1910 to December 1911 (gage heights and discharge measurements 

only), January 1912 to December 1928 (discontinued). Monthly discharge only for some 

periods and yearly mean discharge only after March 1923, published in WSP 1312. Formerly published as Rio Colorado below Questa.

Gage.--Staff gage read twice daily. Altitude of gage is 7,210 ft (from river-profile 

map). Prior to Oct. 1, 1914, staff gage at site 150 ft. upstream at lower datum.

Extremes.--Maximum discharge observed during period October 1914 to August 1915, 524 cfs

Drainage area. 305 sq mi.

Records available.--October 1930 to September 1955 (discontinued) in reports of Geological 

Survey. October 1923 to December 1931 in reports of State engineer.

Gage.--Water-stage recorder. Datum of gage is 5,849.54 ft above mean sea level, datum of 

1929. Prior to Nov. 30, 1938, at site about 1 mile upstream at different datums. 

Nov. 30, 1938, to Aug. 1, 1941, at site about three-quarters of a mile upstream at datum 

about 69.0 ft higher.

Average discharge.--32 years (1923-55), 83.4 cfs (60,380 acre-ft per year).

Extremes.--1930-55: Maximum discharge determined, 2,180 cfs Aug. 22, 1946 (gage height, 

7.00 ft); minimum daily, 0.2 cfs June 27, 1950, July 8, 22, Aug. 17, 1951.

Revisions. The maximum discharges for the water years 1931-33, 1935, 1937-38, 1941, 

published in WSP 733, 748, 788, 828, 858, and 928 are considered to be in error, owing 

to absence of sufficient information for extending the rating to the stages encountered, 

and should not be used.

The maximum discharge for the water year 1947 has been revised to 1,210 cfs Aug. 31, 

1947 (gage height, 5.94 ft), superseding figure published in WSP 1088.

Remarks. Diversions above station for irrigation of about 6,500 acres, a small part of 

which is below gage.

Revisions. Revised figures of discharge, in cubic feet per second, for the water years 

1931-32 and 1941, superseding those published in WSP 733, and 928, are given herein. 

Figures of daily discharge for July 6-25, 1932, published in WSP 733, are considered to 

be in error and cannot be corrected owing to unreliable gage heights and uncertain stagedischarge relation. The peak discharges for July 14, Sept. 2,4, 1938, May 14, 1941, 

published in WSP 858 and 928,are considered to be in error, owing to the absence of 

sufficient information for extending the rating to the stage encountered and should not 

be used.

2 discharge measurements, and weather records.
DISCHARGE MEASUREMENTS AT POINTS OTHER THAN QAQING STATIONS 515

Measurements of streamflow made at points other than regular gaging stations in the area 

covered by this report 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
