SURFACE WATER SUPPLY OF WESTERN GULF OF 

MEXICO, 1910.

By W. B. FREEMAN and J. G. MATHEES.

INTRODUCTION.

AUTHORITY FOB INVESTIGATIONS.

This volume contains results of measurements of the flow of certain 

streams in the United States. The work was performed by the waterresources branch of the United States Geological Survey, either independently or in cooperation with private or State organizations. The 

organic law of the Geological Survey (Stat. L., vol. 20, p. 394) contains 

the following paragraph:

Provided that this officer [the Director] shall have the direction of the geological 

survey and the classification of public lands and examination of the geological structures 

mineral resources, and products of the national domain.

As water is the most abundant and most valuable of the minerals, 

the investigation of water resources is authorized under the provision 

for examining mineral resources. The work has been supported since 

the fiscal year ending June 30, 1895, by appropriations in successive 

sundry civil bills passed by Congress under the following item:

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

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

of report^ upon the best methods of utilizing the water resources.

The appropriations that have been made for this purpose are as 

follows:

Annual appropriations for the fiscal year ending June 30 

1895............................................................... $12, 500

1896. .............................................................. 20, 000

1897 to 1900, inclusive. ............................................. 50,000

1901 to 1902, inclusive. ............................................. 100,000

1903 to 1906, inclusive.............................................. 200,000

1907. .............................................................. 150,000

1908 to 1910, inclusive. ............................................. 100,000

1911. .............................................................. 150,000

SCOPE OF INVESTIGATIONS.

These investigations are not complete nor do they include all the 

streams that might purposefully be studied. The scope of the work 

is limited by the appropriations available. The field covered is the

7
8 SURFACE WATER SUPPLY, 1910, PART VIII.

widest and the character of the work is believed to be the best possible 

under the controlling conditions. The work would undoubtedly have 

greater scientific importance and ultimately be of more practical value 

if the money now expended for wide areas were concentrated on a few 

small drainage basins; but such a course is impossible because general 

appropriations made by Congress are applicable to all parts of the 

country. Each part demands its proportionate share of the benefits.

It is essential that records of stream flow shall be kept during a 

period of years long enough to determine within reasonable limits the 

entire range of flow from the absolute maximum to the absolute 

minimum. The length of such a period manifestly differs for different 

streams. Experience has shown that the records for some streams 

should cover 5 to 10 years and those for other streams 20 years or even 

more, the limit being determined by the relative importance of the 

stream and the relation of the results to other long-time records on 

adjacent streams.

In the performance of this work an effort is made to reach the highest degree of precision possible with a rational expenditure of time 

and a judicious expenditure of a small amount of money. In all engineering work there is a point beyond which refinement is needless and 

wasteful, and this statement applies with especial force to stream-flow 

measurements. It is confidently believed that the stream-flow data 

presented in the publications of the Survey are in general sufficiently 

accurate for all practical purposes. Many of the records are, however, of insufficient length, owing to the unforeseen reduction of appropriations and consequent abandonment of stations. All persons are 

cautioned to exercise the greatest care in using such incomplete records.

Records have been obtained at nearly 2,000 different points in the 

United States. The surface Water supply of small areas in Seward 

Peninsula and the Yukon-Tanana region, Alaska, and in Hawaii has 

also been investigated. During 1910 regular gaging stations were 

maintained by the Survey and cooperating organizations at about 

.1,100 points in the United States, and many discharge measurements 

were made at other points. Data were also obtained in regard to precipitation, evaporation, storage reservoirs, river profiles, and water 

power in many sections of the country and will be made available in 

the regular surface water-supply papers and in special papers from 

time to time.

PUBLICATIONS.

The data on stream flow collected by the United States Geological 

Survey have appeared in the annual reports, bulletins, and watersupply papers. Owing to natural processes of evolution and to 

changes in governmental requirements, the character of the work and 

the territory covered by these different publications have varied
WESTERN GULF OF MEXICO. 9

greatly. For the purpose of uniformity in the presentation of reports 

a general plan has been agreed upon by the United States Keclamation 

Service, the United States Forest Service, the United States Weather 

Bureau, and the United States Geological Survey, according to which 

the area of the United States has been divided into 12 parts, whose 

boundaries coincide with certain natural drainage lines. The areas 

so described are indicated by the following list of papers on surface 

water supply for 1910. The dividing line between the north Atlantic 

and south Atlantic drainage areas lies between York and James 

rivers.

NOTE. No data regarding stream flow are given in the 15th and 17th annual reports.

The records at most of the stations discussed in these reports extend 

over a series of years. An index of the reports containing records 

prior to 1904 has been published in Water-Supply Paper 119.

The first table which follows gives, by years and drainage basins, 

the numbers of the papers on surface water supply published from 

1899 to 1909. Wherever the data for a drainage basin appears in 

two papers the number of one is placed in parentheses and the portion of the basin covered by that paper is indicated in the second 

table. For example, in 1904 the data for Missouri River were published in Water-Supply Papers 130 and 131, and the portion of the 

records contained in Water-Supply Paper 131, as indicated by the 

second table, is that relating to Platte and Kansas rivers.

The order of treatment of stations in any basin in these papers is 

downstream. The main stem of any river is determined by measuring or estimating the drainage area; that is, the headwater stream 

having the largest drainage area is considered the-continuation of the 

main stream and local changes in name and lake surface are disregarded. Records for all stations from the source to the mouth of the 

main stem of the river are presented first, and records for the tributaries in regular order from source to mouth follow, all records for each 

tributary basin being given before those of the next basin below.

The exceptions to this rule occur in the records for Mississippi River, 

which are given in four parts, as indicated above, and in the records 

for large lakes, where it is simpler to take up the streams in regular 

order around the rim of the lake than to cross back and forth over 

the lake surface.

DEFINITION OF TERMS.

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

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

into two groups (1) those which represent a rate of flow, as secondfeet, gallons per minute, miner's inches, and run-off in second-feet 

per square mile, and (2) those which represent the actual quantity of 

water, as run-off in depth in inches and acre-feet. The units used in 

this series of reports are second-feet, second-feet per square mile, and 

run-off in inches and acre-feet. They may be defined as follows:

"Second-foot" is an abbreviation for cubic foot per second and is 

the rate of discharge of water flowing in a stream 1 foot wide, 1 foot
12 SUEFAGE WATER SUPPLY, 1910, PART VIII.

deep, at a rate of 1 foot per second. It is generally used as a fundamental unit from which others are computed by the use of the factors 

given in the following table of equivalents:

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

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

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

regards time and area.

"Kun-off in inches" is the depth to which the drainage area would 

be covered if all the water flowing from it in a given period were conserved and uniformly distributed on the surface. It is used for comparing run-off with rainfall, which is usually expressed in depth in 

inches.

"Acre-foot"- is equivalent to 43,560 cubic feet, and is the quantity 

required to cover an acre to the depth of 1 foot. It is commonly used 

in connection with storage for irrigation work.

The following is a list of convenient equivalents for use in hydraulic 

computations:

1 second-foot equals 40 California miner's inches (law of Mar. 23, 1901).

1 second-foot equals 38.4 Colorado miner's inches.

1 second-foot equals 40 Arizona miner's inches.

1 second-foot equals 7.48 United States gallons per second; equals 448.8 gallons

per minute; equals 646,272 gallons for one day. 

1 second-foot equals 6.23 British imperial gallons per second. 

1 second-foot for qne year covers 1 square mile 1.131 feet or 13.572 inches deep. 

1 second-foot for one year equals 31,536,000 cubic feet. 

1 second-foot equals about 1 acre-inch per hour. 

1 second-foot for one day covers 1 square mile 0.03719 inch deep. 

1 second-foot for one 28-day month covers 1 square mile 1.041 inches deep. 

1 second-foot for one 29-day month covers 1 square mile 1.079 inches deep. 

1 second-foot for one 30-day month covers 1 square mile 1.116 inches deep. 

1 second-foot for one 31-day month covers 1 square mile 1.153 inches deep. 

1 second-foot for one day equals 1.983 acre-feet. 

1 second-foot for one 28-day month equals 55.54 acre-feet. 

1 second-foot for one 29-day month equals 57.52 acre-feet. 

1 second-foot for one 30-day month equals 59.50 acre-feet. 

1 second-foot for one 31-day month equals 61.49 acre-feet. 

100 California miner's inches equals 18.7 United States gallons per second. 

100 California miner's inches equals 96 Colorado miner's inches. 

100 California miner's inches for one day equals 4.96 acre-feet. 

100 Colorado miner's inches equals 2.60 second-feet. 

100 Colorado miner's inches equals 19.5 United States gallons per second.

EXPLANATION OF DATA.

For each drainage basin there is given a brief general description 

covering such items as area, source, tributaries, topography, geology, 

forestation, rainfall, irrigation, storage, power, and other interesting 

or important facts.

For each regular current-meter gaging station the following data 

so far as available are given: Description of station, list of discharge 

measurements, table of daily gage heights, table of daily discharges, 

table of monthly and yearly discharges and run-off. For stations 

located at weirs or dams the gage-height table is omitted.

In addition to statements regarding the location and installation of 

current-meter stations the descriptions give information in regard to 

any conditions which may affect the constancy of the relation of 

gage height to discharge, covering such points as ice, logging, shifting channels, and backwater; also information regarding diversions 

which decrease the total flow at the measuring section. Statements 

are also made regarding the accuracy and reliability of the data.

The discharge-measurement table gives the results of the discharge 

measurements made during the year, including the date, name of 

hydrographer, width and area of cross section, gage height, and 

discharge in second-feet.

The table of daily gage heights records the daily fluctuations of 

the surface of the river as found from the mean of the gage readings 

taken each day. At most stations the gage is read in the morning 

and in the evening. The gage height given in the table represents 

the elevation of the surface of the water above the zero of the gageAll gage heights affected by the presence of ice in the streams or by
14 SURFACE WATER SUPPLY, 1910, PART VIII.

backwater from obstructions are published as recorded, with suitable 

footnotes. The rating table is not applicable for such periods unless 

the proper corrections to the gage heights are known and applied. 

Attention is called to the fact that the zero of the gage is placed at 

an arbitrary datum and has no relation to zero flow or the bottom of 

the river. In general, the zero is located somewhat below the lowest 

known flow, so that negative readings shall not occur. ,

The discharge measurements and gage heights are the base data 

from which rating tables, daily discharge tables, and monthly discharge tables are computed.

The rating table gives, either directly or by interpolation, the discharge in second-feet corresponding to every stage of the river 

recorded during the period for which it is applicable. It is not published in this report, but can be determined from the daily gage 

heights and daily discharges for the purpose of verifying the published results as follows:

First plot the discharge measurements for the current and earlier 

years on cross-section paper, with gage heights in feet as ordinates 

and discharge in second-feet as abscissas. Then tabulate a number 

of gage heights taken from the daily gage-height table for the 

complete range of stage given and the corresponding discharges for 

the days selected from the daily discharge table and plot the values 

on cross-section paper. The last points plotted will define the rating 

curve used and will lie among the plotted discharge measurements. 

After drawing the rating curve, a table can be developed by scaling 

off the discharge in second-feet for each tenth foot of gage height. 

These values should be so adjusted that the first differences shall 

always be increasing or constant, except for known backwater 

conditions.

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

corresponding to the observed gage heights as determined from the 

rating tables.

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

gives the mean flow, as determined from the rating table, for the day 

when the mean gage height was highest. As the gage height is 

the mean for the day, it does not indicate correctly the stage when 

the water surface was at crest height and the corresponding discharge 

was consequently larger than given in the maximum column. Likewise, in the column of "Minimum" the quantity given is the mean 

flow for the day when the mean gage height was lowest. The 

column headed "Mean" is the average flow in cubic feet for each 

second during the month. On this the computations for the remaining columns, which are defined on pages 11 and 12, are based.

The field methods used in the collection of the data presented in 

this series of reports are described in the introductory sections of
WESTERN GULF OF MEXICO. 15

Water-Supply Papers 261 to 272, inclusive, " Surface water supply of 

the United States, 1909." Plate I shows typical gaging stations, 

indicating the method of suspending the current meter; Plate II 

shows the various types of current meters 1 used in the work.

ACCURACY AND RELIABILITY OF FIELD DATA AND COMPARATIVE

RESULTS.

The accuracy of stream flow depends primarily on the natural conditions at the gaging station and on the methods and care with 

which the data are collected. Errors of the first group depend on 

the degree of permanency of channel and of permanency of the relation of discharge to stage. Errors of the second group are due, first, 

to errors in observation of stage; second, to errors in measurements 

of flow; and third, to errors due to misinterpretation of stage and 

flow data.

Practically all discharge measurements made under f air conditions 

are well within 5 per cent of the true discharge at the time of observation. Inasmuch as the errors of meter measurements are largely 

compensating, the mean rating curve, when well defined, is much 

more accurate than the individual measurements. Numerous experiments made to test the accuracy of current-meter work show that 

it compares very favorably with the results from standard weirs and, 

owing to simplicity of methods, usually gives results that are much 

more reliable than those from stations at dams where the coefficient 

may be uncertain and conditions of flow are complicated.

The work is, of course, dependent on the reliability of the gage 

observers. With relatively few exceptions, the observers perform 

their work honestly. The records are, however, closely watched and 

the cause of any discrepancy is investigated. It is obvious that one 

gage reading a day does not always give the mean height for that 

day. As an almost invariable rule, however, errors from this source 

are compensating and virtually negligible in a period of one month, 

although a single day's reading may, when taken by itself, be considerably in error.

An effort is made to visit every station at least once each year for 

the purpose of making a measurement to determine the constancy of 

conditions of flow since the last measurement made in the preceding 

year, and also to check the elevation of the gage. On account of 

lack of funds or for other causes some stations were not visited during 

the current year. If conditions of flow have been reasonably permanent up to the time of the last preceding measurement, it is considered best to publish estimates of discharge based on the latest 

verified rating, curve rather than to omit them altogether, although

1 See Hoyt, J. C., and others, Use and care of current meter as practiced by the United States Geological Survey: Trans. Am. Soc. C. E., vol. 66,1910, p. 70.
16 SURFACE WATER SUPPLY, 1910, PART VIII.

it should be distinctly understood that such records are at times 

subject to considerable error. This is also true, although to a less 

degree, of the period of records since the date of the last measurement of the current year. As a rule, the accuracy notes are based 

on the assumption that the rating curve used is strictly applicable 

to the current year.

In order to give engineers and others information regarding the 

probable accuracy of the computed results, footnotes are added to 

the daily-discharge tables, stating the probable accuracy of the rating 

tables used, and an accuracy column is inserted in the monthly-discharge table. For the rating tables "well defined" indicates, in 

general, that the rating is probably accurate within 5 per cent; 

"fairly well defined," within 10 per cent; "poorly defined" or 

"approximate," within 15 to 25 per cent. These notes are very 

general and are based on the plotting of the individual measurements 

with reference to the mean rating curve.

The accuracy column in the monthly-discharge table does not 

apply to the maximum or minimum nor to any individual day, but 

to the monthly mean. It is based on the accuracy of the rating, the 

probable reliability of the observer, and knowledge of local conditions. 

In this column A indicates that the mean monthly flow is probably 

accurate within 5 per cent; B, within 10 per cent; C, within 15 per 

cent; D, within 25 per cent. Special conditions are covered by 

footnotes.

USE OF THE DATA.

In general the base data which are collected in the field each year 

by the Survey engineers are published, not only to comply with the 

law, but also for the express purpose of giving to any engineer the opportunity of examining the computed results and of changing and adjusting them as may seem best to him. Although it is believed that the 

rating tables and computed monthly discharges are as good as the 

base data up to and including the current year will warrant, it should 

always be borne in mind that the additional data collected at each 

station from year to year nearly .always throw new light on data 

already collected and published, and hence allow more or less improvement in the computed results of earlier years. It is therefore expected 

that the engineer who makes use of the figures presented in these 

papers will verify all ratings and make such adjustments for earlier 

years as may seem necessary. The work of compiling, studying, revising, and repubUshing data for different drainage basins for 5 or 10 

year periods or more is carried on by the United States Geological 

Survey so far as the funds for such work are available.

The estimates in the table of monthly discharge are so arranged 

as to give only a general idea of the conditions of flow at the station.

and it is not expected that they will be used for other than preliminary 

estimates.

The daily discharges are published to allow a more detailed study 

of the variation in flow and to determine the periods of deficient flow.

COOPERATIVE DATA.

Cooperative data of various kinds and data regarding the run-off 

at many stations maintained by private funds are published in the 

surface water supply reports of the United States Geological Survey.

Many stations throughout the country are maintained for specific 

purposes by private parties who supply the records gratuitously to 

the United States Geological Survey for publication. When such 

records are furnished by responsible partiejs and appear to be reasonably accurate, they are verified, so far a^s possible, and estimated 

values of accuracy are given. Records that are clearly worthless or 

misleading are not published. As it is, however, impossible to verify 

completely all such records for lack of jfunds or for other causes 

they are published for what they are worth|, as they are of value as a 

matter of record and afford at least approximate information regarding stream flow at the particular localities. The Survey does

however, assume any responsibility for inaccuracies found in smch 

records, although most of them are believefi to be reasonably good.

BRAZOS RIVER DRAINAGE BASIN.

DESCRIPTION.

Brazos River rises in the Staked Plains in Hale and Lamb counties, 

western Texas, and takes a general southeasterly course into the 

Gulf of Mexico, which it enters south of the mouth of Trinity River. 

Its drainage basin is entirely within the State of Texas.

BRAZOS RIVER AT WACO, TEX.

This station was established September 14, 1898, at the suspension 

bridge on Bridge Street, Waco, Tex.

A single-span truss bridge crosses the river at an angle of 76° about 

300 feet above the suspension bridge.

Discharge measurements are made from the suspension bridge. A 

boxed chain gage is fastened to the downstream upper chord of the 

stiffening truss of the suspension bridge.

At low stages the rating curve is not stable on account of the shifting sands. A few hundred feet below the gage sand is taken out 

of the river for commercial purposes. Between this point and the 

gage the channel is modified at low stages to direct the current away 

from or toward certain discharge pipes from factories.

The following measurement was made by T. U. Taylor:

August 25, 1910: Width, 9 feet; area of section, 42 square feet; gage height, 120 

feet; discharge, 6 second-feet.

26 SURFACE WATER SUPPLY, 1910, PART VIII.

COLORADO RIVER (OF TEXAS) DRAINAGE BASIN. 

DESCRIPTION.

Colorado Kiver rises in the extreme western portion of the State, 

within a few miles of the eastern boundary of New Mexico, and flows 

in a general southeasterly direction, emptying into the Gulf of Mexico, 

in Matagorda County. The drainage area, comprising 40,000 square 

miles above Columbus, extends into the corner of New Mexico. The 

principal tributaries of the Colorado are the Concho, the San Sab a, 

and the Llano. The Concho carries a greater quantity of water than 

the Colorado at their point of junction, furnishes water for irrigation 

and water power, and supports in Irion and Tom Green counties some 

excellent irrigation systems.1

The Colorado at Austin emerges from a canyon; from Austin to the 

Gulf it traverses a rather flat country, and its waters are utilized for 

many power plants. A large acreage of rice is irrigated by canals that 

obtain their water from the Colorado.

COLORADO RIVER AT AUSTIN, TEX.

This station, which was established December 21, 1897, was originally located at the dam near Austin, Tex. Gage heights were first 

obtained on the crest of the Austin dam August 13, 1895, and were 

continued from that date until the failure of the dam in April, 1900. 

On the failure of the dam the station was moved to the Congress 

Avenue Bridge, south of the city.

A staff gage consisting of upright posts driven into the bank of the 

river is located near the bathhouse about 150 feet above the bridge; 

for higher stage the first pier from the north has been marked up to 

21.00 feet; for stages above 21.00 feet a chain gage is used.

The low-water level at this point has been gradually falling for several years. This decrease has been caused by the erosion of the channel about 200 yards below the highway bridge. Under the highway 

bridge the water spreads out into a large pool, the outlet of which is 

through two contracted sections below, the main one being that in 

which the erosion has taken place. The lowest level recorded from 

gage observations is 0.45 foot, on August 15-20, 1910.

NOTE. From Aug. 15 to Sept. 10 the flow of Barton's springs at Austin was 19 second-feet. If this amount 

be added to the discharges at the dam site and the falls (Aug. 16-18) it will give the discharges at the 

bridge for those days.

32 SUEFACE WATEE SLTPPLY, 1910, PART VIII.

COLORADO RIVER AT COLUMBUS, TEX.

This station was established in December, 1902. It is located at 

the highway bridge east of Columbus.

A gage is marked on the downstream side of the pier on the west 

side of the three-span highway bridge. Gage datum is taken at 50 

feet below the top of this pier, and the observer measures down from 

this point with a tagged chain and lead weight.

Discharge measurements are made from bridge at which the gage 

is located.

The following discharge measurement was made by T. U. Taylor:

August 23, 1910: Gage height, 4.7 feet; discharge, 124 second-feet.

Daily gage height, in feet, of Colorado River at Columbus, Tex., for 1907-1910.

BIO GRANDE DRAINAGE BASIN. 

GENERAL FEATURES.

The Rio Grande basin is a long, narrow strip of country extending 

from the southern part of Colorado southeastward to the Gulf of 

Mexico. The perennial supply of water for the upper third of this 

basin comes principally from a comparatively small area of about 

2,000 square miles of lofty mountains in Colorado and the extreme 

northern part of New Mexico. The Conchos enters the river from 

the Mexican side some 200 miles below El Paso and brings a good 

perennial flow as well as enormous floods in the summer and fall. 

Pecos and Devils rivers and springs also substantially augment the 

perennial supply, and many other tributaries furnish flood discharges, 

so that the "lower river" is not dependent on the mountain area for 

its perennial flow. The flood season above the Conchos is May and 

June; below it is August and September. Frequently the river is 

dry at El Paso when the lower river country is inundated. In addition to the areas contributing a perennial supply of water and a 

spasmodic supply, a vast area of "lost river" basins which supply 

no water at any time, may, from topographic considerations, be 

included within this great catchment basin.

The Rio Grande rises in the mountainous area to the south and 

east of the Continental Divide in southwestern Colorado, flows eastward for a time as a mountain stream, enters the San Luis Valley 

about 80 miles below its source and then turns southward. In this 

valley it receives from the west Alamos, La Jara, and Conejos rivers; 

from the east the Trinchera, Culebra, and Rio Costilla; and possibly from the north the waters of Saguache and San Luis rivers, 

by seepage. About 4 miles north of the Colorado State line it enters 

a long canyon locally known as the Rio Grande canyon. From the 

east there enter this canyon two tributaries, Red River and Rio 

Hondo.

This canyon is 300 or 400 feet deep in places, appearing from above 

as a gash in an otherwise level mesa. Its south end is 3 miles above 

Embudo, N. Mex., where the walls open and the river enters Espanola Valley. The general slope of the valley is toward the south, 

the river descending, however, more rapidly than the surface of the 

country. In the valley above Embudo the river receives from the 

east Taos River, Embudo Creek, and other small streams, and in 

Espanola Valley it is increased by the Chama, flowing in from the 

west, and by a number of streams from the east.

At the lower end of Espanola Valley the river passes through White 

Rock Canyon, a gorge in a range of hills stretching from the Jemez 

to the Santa Fe Mountains. From Pena Blanca, near the lower end 

of this canyon, nearly to Socorro, the river flows in a valley 1 to 3
38 SURFACE WATER SUPPLY, 1910, PART VIII.

miles wide, bounded on each, side by mesas that rise 300 to 600 feet 

above the river. About 20 miles below Pena Blanca the Jemez 

enters from the west, and 60 miles or more below Albuquerque the 

Puerco comes in from the same side. The Puerco is a torrential 

stream with no perennial flow. Below these streams the Rio Grande 

has no tributaries of note until it receives the Pecos, about 400 miles 

by river below El Paso.

At and below Socorro the valley contracts until it becomes too 

narrow for agriculture, but from San Antonio to San Marcial its 

width ranges from 1 to 2 miles. Below San Marcial the river swings 

to the west around the Cristobal and Caballos mountains, which lie 

along the west edge of the Jornada del Muerto, the valley from San 

Marcial to Rincon being narrow, low, and marshy. At Rincon the 

river enters a canyon which extends to Fort Selden, a distance of 15 

miles. The Mesilla Valley, the most fertile valley in New Mexico, 

begins below Fort Selden and extends to the pass above El Paso, a 

distance of over 50 miles. Above El Paso the banks of the river 

again assume the canyon-like character for 3 miles, and the river 

emerging from this enters the Ysleta Valley, now commonly called 

the El Paso Valley.

The canyons above these valleys are not cut into hard, indurated 

rocks, but are bordered in many places by steep walls of comparatively soft, friable sandstones, alternating with conglomerates or 

beds of clay, the whole series in the northern part of New Mexico, at 

least, being capped by a vesicular lava. The fall through these 

canyons being great, the down-cutting is rapid, and thus the waters 

are supplied constantly with fresh detritus, part of which is deposited 

in turn in the valley below.

From El Paso to the Gulf the river forms the boundary between 

Mexico and the United States.

From source to mouth the Rio Grande is nearly 2,000 miles long, 

and its drainage area comprises about 248,000 square miles.

Many national forests have been established on the headwaters of 

the Rio Grande and its tributaries, both in Colorado and New Mexico. 

The drainage basin of the Rio Grande, exclusive of the Pecos, includes 

between 5,000 and 6,000 square miles of merchantable timber land, 

6,000 square miles of woodland and sparsely timbered land, and 2,000 

square miles of burned and cut-over land, the remainder being sagebrush and open land.

The largest tributaries are the Conchos, which enters from the 

Mexico side, 200 miles below El Paso; the Conejos, which joins the 

Rio Grande just above the Colorado-New Mexico line; the Chama, 

which enters it in Espanola Valley; the Pecos, which joins it in the 

southwestern part of Texas; and Devils River, about 50 miles below
WESTEBN GULF OF MEXICO. 39

the Pecos. Most of the remaining tributaries are intermittent in 

character.

The mountains at the headwaters reach altitudes up to 14,000 feet 

above sea level. At Albuquerque, N. Mex., the elevation of the river 

is 5,000 feet and it leaves the Territory at an elevation of about 4,000 

feet.

The rainfall varies greatly from year to year and from source to 

mouth, its irregularity making it very difficult to give averages. The 

annual precipitation in the mountainous district of Colorado that 

is, along the upper Rio Grande ranges from 15 to 25 inches. In the 

northern part of New Mexico it ranges from 10 to ,15 inches, and in 

the southern part from 5 to 12 inches.

In the mountains of Colorado the river is covered with a foot or 

more of ice from early in the winter until late in the spring. During 

severe winters the river is frozen over at times in northern New 

Mexico, and the snowfall is often very heavy. From the melting of 

the snows in Colorado and New Mexico comes the spring floods.

Irrigation is now practiced extensively in the following valleys 

along the Rio Grande and its smaller tributaries:

San Luis Valley, beginning a short distance above Del Norte and 

extending to the mouth of Conejos River. This district contains 

probably the largest cultivated area along the Rio Grande, aggregating nearly half a million acres.

Valleys of the Taos district, lying on the east side of the river 

below the Colorado line and including the valleys of Red River, 

Arroyo Hondo, and Taos. The Taos Valley surpasses the others 

both in water facilities and in area cultivated.

Espanola Valley, located south of the Taos district and Tres 

Piedras Mesa. It lies along the river, and, as in the Taos country, 

agriculture has been practiced for years.

Albuquerque district, including the valley from Pena Blanco to 

San Marcial. The system of irrigation is practically the same as the 

old Pueblo Indian system. In the last few years, however, new settlers have adopted progressive methods and have greatly increased 

the duty of water.

Mesilla Valley, next to San Luis Valley the most important agricultural area along the Rio Grande. The valley broadens just below 

Selden and continues generally broad and fertile for a distance of 

35 miles or beyond the Texas line.

Along the Rio Grande and its tributaries in Colorado and New 

Mexico are available reservoir sites equal to storing of all flood waters. 

The largest reservoir in the country is about to be built near Engle, 

N. Mex. It will impound 2,500,000 acre-feet of water for the irrigation of nearly 200,000 acres of land in New Mexico, Texas, and 

Mexico.
40 SUBFACE WATEB SUPPLY, 1910, PART VIII.

The estimated power available on the Kio Grande and its tributaries, from its source *io El Paso, Tex., is theoretically as follows:

Minimum horsepower........................................ 123, 500

Minimum horsepower, six high months........................ 241,000

Horsepower from storage, six months period.................. 405,000

Developments will, however, be made chiefly on the upper tributaries in Colorado and a few of the mountain streams in New Mexico, 

and will not amount to more than 100,000 horsepower. At present 

very few water-power plants of any importance are operated in the 

drainage basin. The waters of the Kio Grande have been used only 

for irrigation and domestic purposes, but those, of some of the tributaries have also been used in mining.

The years of greatest flow on the upper Rio Grande appear to be 

1906 and 1907; 1902 and 1908 were low-water years.

The determination of the amount of water in the Rio Grande is of 

importance, both on account of its use in irrigation and from its 

bearing upon interstate and international distribution of water. 

Most of the New Mexico and all of the Texas stations down to Eagle 

Pass are maintained by the United States section of the International 

Water Commission (prior to July 1, 1910, International Boundary 

Commission). The data used for the following stations have been 

collected by W. W. Follett, consulting engineer for the commission, 

and have been furnished through the courtesy of Gen. Anson Mills, 

commissioner:

Rio Grande near San Marcial, N, Mex.

Kio Grande near El Paso, Tex.

Rio Grande above Presidio, Tex.

Rio Grande below Presidio, Tex.

Rio Grande near Langtry, Tex.

Rio Grande at Eagle Pass, Tex.

Pecos River near Moorhead, Tex.

Devils River near Devils River Station, Tex.

On account of the shifting character of the river beds at the international water stations, no rating tables have been prepared. The 

estimated monthly discharges are from daily discharges computed 

by Mr. Follett directly from the discharge measurements.

The five stations from Laredo down (Laredo, Roma, Brownsville, 

Salado hear Guerrero, and San Juan at Santa Rosalia ranch) are 

maintained by the Mexican section of the commission.

RIO GRANDE PROPER. 

BIO GRANDE AT THIBTYMILE BRIDGE, NEAR CREEDE, COLO.

This station, which was established June 18, 1909, is about 30 miles 

west of Creede, Colo., and about 200 feet above the mouth of Big 

Squaw Creek at an elevation of about 9,200 feet above sea level.
WESTEBN GULF OF MEXICO. 41

No water is diverted above the station and none for many miles 

below except a little for meadow irrigation. The station is about 

one-half mile downstream from the proposed reservoir of the 

Farmers Union Irrigation Co., which will store flood water to irrigate 

land in the valley 70 miles downstream. The drainage area at the 

station is about 160 square miles. The records at this station have 

been taken at the expense of the company by its engineers under 

the general direction of the United States Geological Survey.

The chain gage, the datum of which has remained constant, is on 

the right bank 200 feet upstream from Thirtymile Bridge; discharge 

measurements are made from a cable 30 yards below the gage.

This stream is frozen over for a number of months each year and 

there is also a large snowfall in that locality.

RIO GRANDE NEAR CREEDE, COLO.

The station, which was established April 24,1907, is located at the 

three-span highway bridge a quarter of a mile south of Wason siding, 

on the Creede branch of the Denver & Rio Grande Railroad, about 3 

miles from Creede, and is a few miles above the site of a proposed 

dam and reservoir. Willow Creek (Goblin Creek) enters the river a 

short distance upstream from Wason, and Goose Creek enters at 

Wagonwheel Gap, about 5 miles below. The drainage area above 

the station is about 700 square miles.

The chain gage is fastened to the downstream side of left span, 

and discharge measurements are also made from the same side. A 

Bristol automatic gage was installed at the bridge by the State engineer of Colorado on September 23, 1910. Readings of this gage 

have been referred to the datum of the chain gage.

Except for a little meadow irrigation, no water is diverted above 

this station. Two or three reservoirs are about to be constructed on 

the upper waters of the Rio Grande and its tributaries above Wason. 

Among others may be mentioned the Farmers' Union Irrigation
WESTERN GULF OF MEXICO. 43

Co.'s reservoir on the main stream, about 35 miles above. The 

proposed reservoir near Wason will have a capacity almost equal 

to the normal annual flow of the river.

The winters are long and very severe in this locality, and the 

stream has a heavy ice cover for several months. The bridge piers 

cause eddies, which materially affect the accuracy of measurements. 

The river channel is rough and the velocity high at flood stages, so 

that results obtained at this station are only fair.

The datum of the gage has not been changed since the station was 

established.

NOTE. Mean discharge for January and February estimated on the basis of two measurements. 

RIO GRANDE NEAR DEL NORTE, COLO.

This station, which was established in the fall of 1889, was originally located about 2 miles above Del Norte, and records were taken 

more or less continuously until May 16, 1908, when a new station 

was established at the new State highway bridge about 6 miles above 

Del Norte, near the upper edge of the San Luis Valley. Some inflow
WESTERN GULF OF MEXICO. 45

takes place between the two points at certain seasons of the year, 

so that the mean annual flow at the State bridge is somewhat less 

than that at the old station. The new station is about 4 miles above 

the mouth of Los Pinos Creek, below the mouth of Wolf Creek, 

and about 10 miles below the mouth of the South Fork of the Rio 

Grande. The drainage area is 1,440 square miles. The old station 

is just above the mouth of Los Pinos Creek.

The diversions from the Eio Grande and its tributaries above this 

point are all small and are used chiefly for meadow irrigation. They 

represent a very small percentage of the total flow of the stream. 

The largest ditch takes water out at Del Norte, about 2 miles below 

the original station. From this canal and many others diverted at 

various points nearly 300,000 acres of land in Colorado are now 

being irrigated from the Rio Grande.

Numerous small storage reservoirs under construction or in contemplation on the tributaries of the Rio Grande will store a large 

proportion of flood waters, but all the waters of the upper Rio Grande 

have been filed upon.

Practically no change was made in the datum of the gage at the 

old station during its maintenance, and this old gage is still being 

used by the water commissioner in that irrigation district of the 

State. The present chain gage is located on the highway bridge, 

and the readings have no determined relation to those taken at the 

old gage. On November 8, 1910, the State engineer established a 

Bristol automatic gage on the right bank a short distance upstream 

from the bridge. The readings of this gage have been referred to 

the datum of the chain gage. Discharge measurements are made 

from the downstream side of the bridge.

Very good results can be obtained at the present station except during the three or four winter months when the flow is affected by ice.

RIO GRANDE NEAR LOBATO8, COLO.

This station was established June 28, 1899, at the State bridge 

about 15 miles east of Antonito, in T. 33 N., R. 11 E., a few miles 

above the Colorado-New Mexico line. The data are valuable in 

connection with the proposed Engle reservoir of the United States 

Reclamation Service, and will be used in the adjudication, which 

must eventually be made, of all water rights along the Rio Grande.

Conejos River enters about 7 miles above the station. A large 

part of the normal flow of the river is diverted above this station 

during the irrigation period. About 450,000 acres of land are irrigated, and more will be put under water in connection with some of 

the proposed reservoir'systems above.

Ice forms on the river at this point for about three months during 

the winter, but open water may prevail through part of this period.

The datum of the gage has not been changed since the station 

was established. The present chain gage is fastened to downstream 

handrail of bridge. Measurements are also made from downstream 

side of this bridge. On March 23, 1910, the State engineer of Colorado established a Bristol automatic gage at the bridge, which was 

used to some extent during the season and the readings of which have 

been referred to chain-gage datum. Very good results have been 

obtained at this station. The river channel is fairly permanent, 

being a gash cut in the lava rock. Occasionally during low water 

some sediment is deposited, but it is scoured out in times of flood.

BIO GRANDE AT RIO GRANDE NEAR BUCKMAN, N. HEX.

This station was established February 1, 1895, since which, time 

records have been obtained at various points. It is located at the 

Denver & Rio Grande Railroad bridge crossing the river one-eighth 

mile east of Rio Grande (a water-tank station). The bridge is about 

4 miles above Buckman, a lumber camp, and about 2 miles below 

San Ildefonso, an Indian pueblo.

The original gage was located on left bank 180 feet above the

bridge. On March 30, 1904, a vertical rod gage was established at

a new datum on the downstream side of the .railroad pier. The

datum was discontinued December 31, 1905, and was reestablished

99943° WSP 288 11 4
50 SURFACE WATER SUPPLY, 1910, PART VIII.

June 22, 1909, the same gage being used as in 1904. In June, 1910, 

a Friez automatic gage was installed at same location and datum as 

staff gage. The cable above bridge had been removed and measurements were made from railroad bridge. From June 22, 1909, to 

June, 1910, discharge measurements were made from the railroad 

bridge. During 1910 a cable was installed about 3 miles below. 

There are no diversions or important tributaries between the gage 

and the measuring section.

For many miles above this station many large and small ditches 

divert water for irrigation.

The flow of the stream at this point is only slightly affected by ice.

Since 1904 the datum has remained practically unchanged.

EIO GRANDE NEAR SAN MARCIAL, N. MEX.

On August 8, 1889, a station was established near San Marcial and 

a measurement made giving a discharge of 19 second-feet. Soon after 

this date the gage was destroyed and the station abandoned until 

January 29, 1895, when it was reestablished at the Atchison, Topeka 

& Santa Fe Kailway bridge crossing the river 1 mile south of San 

Marcial, N. Mex. The inclined gage installed in 1895 was carried
52 SUEPACE WATER SUPPLY, 1910, PART VIII.

away in 1896 and a wire gage put in its place at the same datum. 

This was soon abandoned and gage heights were obtained by measuring, by means of a graduated rod, the distance from the bridge deck 

to the water surface.

Since January 1, 1901, the station has been maintained by the 

United States section of the International Water Commission (prior 

to July 1, 1910, International Boundary Commission).

The channel is sandy and very shifting. During high stages bridge 

piers interfere with the accuracy of results.

No important tributaries enter in the immediate vicinity.

EIO GRANDE NEAR EL PASO, TEX.

This station was located at the pumping house of the smelter company, 3 miles north of El Paso, Tex. The bed of the stream at that 

point is composed of mud and is constantly shifting. On May 1, 

1897, the station was placed under the charge of W. W. Follett, consulting engineer, International Water Commission (prior to July 1, 

1910, International Boundary Commission),'and by him removed 1 

mile farther up the river to Courchesne's limekiln. Although the 

section is unstable and subject to overflow, it is still the best site for 

a station in the vicinity of El Paso, as the entire bed is constantly 

shifting for many miles above and below. On this account frequent 

discharge measurements are made in order to closely estimate the 

daily discharge.

River heights were measured at the masonry pump-foundation 

pier. As the pier was torn down in October, 1902, an inclined wooden 

gage was established some 60 feet upstream. This has since been 

moved about 300 feet downstream.

RIO GRANDE ABOVE PRESIDIO, TEX.

This station was established April 4, 1900, by the International 

Boundary Commission. It was originally located 9 miles above 

Presidio and 8 miles above the mouth of Rio Conchos, one of the 

principal tributaries of the Rio Grande, and about 200 miles below El 

Paso. The station was in a straight stretch of the river, but in the
WESTERN GULF OF MEXICO. 57

bight of a long bend. In 1905 the river began to erode a cut-off 

across this bend, and the spring flood of 1905 deepened this channel 

to such an extent that more water passed through it than passed 

the station, and it became necessary to abandon the location. In 

September, 1905, the station was moved 8 miles farther upstream 

and rebuilt. Its location was far enough above the mouth of Rio 

Conchos to be free from the effects of backwater from that stream. 

Caving banks necessitated the abandonment of this upper site, and 

the station was moved back to the original site, at the Haciendita, 

July 6, 1909. A new gage was established whose readings are not 

comparable with the old ones. Changes of river bed have closed the 

crevasse which threatened in 1905, and frequent discharge measurements are necessary to determine closely the daily discharge.

The observations at this station have been made under the direction of the United States section of the International Water Commission (prior to July 1, 1910, International Boundary Commission).

BIO GEANDE BELOW PEESEDIO, TEX.

The station was established April 8, 1900, by the International 

Boundary Commission. It is 6 miles below Presidio, 7 miles below 

the mouth of the Rio Conchos, and about 215 miles below El Paso. 

It is at the west end of the canyon section of the Rio Grande. The 

discharge at this station minus the discharge at the station above 

Presidio, Tex., is the discharge of Rio Conchos, except at rare intervals, when some rain water enters the Rio Grande from the north.

The river is fairly straight at the station and for one-fourth mile 

above and below. The right bank is a rocky bluff. The left bank is 

an alluvial deposit and overflows for 750 feet back from the river 

where gravel hills are found. The bed is of shifting sand and is 

affected by a drainage line called Alamos Creek, which reaches the 

river one-fourth mile below the station. This creek is subject to 

torrential floods, which bring large quantities of bowlders and gravel 

into the Rio Grande, forming a temporary dam, which remains, 

throwing backwater on to the gage, until a flood in the river scours 

it out. The extreme floods come from the Rio Conchos, the highest 

recorded gage height being 26.35 feet on September 11, 1904. Frequent discharge measurements are made to determine closely the 

daily flow

The observations at this station have been made under the direction of the United States section of the International Water Commission (prior to July 1,1910, International Boundary Commission).

RIO GRANDE NEAR LANGTRY, TEX.

This station was established in April, 1900, by the International 

Boundary Commission. It is located one-half mile south of Langtry 

station, on the Southern Pacific Railroad, and is about 440 miles 

below El Paso, Tex., at the east end of the canyon section of the 

Rio Grande, and a short distance to the west of the mouth of Pecos 

River, one of the principal tributaries of the Rio Grande.

The right (Mexican) bank is a rock bluff; the left bank is alluvial 

deposit for 200 feet back to a rock bluff. As the river is constantly 

shifting, because of alluvial deposits, frequent discharge measurements 

are made in order to determine closely the daily flow.

Observations at this station have been made under the direction 

of the United States section of the International Water Commission 

(prior to July 1, 1910, International Boundary Commission).

Discharge measurements of Rio Grande near Langtry, Tex., in 1910.

RIO GRANDE BELOW DEVILS RIVER, TEX.

The station was established in April, 1900, by the International 

Boundary Commission. It is alongside the Southern Pacific Railroad 

track, about a mile below the mouth of Devils River and the station 

of Devils River, and about 480 miles below El Paso.
WESTERN GULF OF MEXICO. 65

The bed of the river is rock for a short distance from the left bank; 

the right bank is alluvial deposit, overflowing in extreme high water 

for a distance of some 500 feet back from the river. The left bank is 

a loose rock fill, along which runs the Southern Pacific Railroad.

Frequent discharge measurements are made to determine closely the 

daily flow. The observations at this station have been made under the 

direction of the United States section of the International Water Commission (prior to July 1, 1910, International Boundary Commission) n

Discharge measurements of Rio Grande below Devils River, Tex., in 1910.

RIO GRANDE AT EAGLE PASS, TEX.

The station was established in April, 1900, by the International 

Boundary Commission. It is one-half mile above the highway bridge 

between Eagle Pass, Tex., and Ciudad Porfirio Diaz, Mexico, and 

about 540 miles below El Paso.

The right bank is alluvial deposit, with a bottom back of it about 

1,500 feet wide, which begins to overflow at gage height 22 feet. 

The left bank is shale rock rising abruptly from the river. The bed 

of the stream is constantly shifting, and frequent discharge measurements are necessary to determine closely the daily discharge. The 

section is subject to overflow at high stages. At low water the depth 

is considerable and the velocity slow.

The observations at this station have been made under the direction of the United States section of the International Water Commission (prior to July 1, 1910, International Boundary Commission).

EIO GRANDE NEAR LAREDO, TEX.

The station was established near Nuevo Laredo, Mexico, in April, 

1900, by the International Boundary Commission. It was intended 

to measure the river from the highway bridge connecting Laredo, Tex., 

with Nuevo Laredo, Tamaulipas, and the gage was established on 

the right bank just above the bridge. Measurements were kept up
70 SUKFACE WATER SUPPLY, 1910, PAET VIII.

by the Mexican section of the commission until September 24, 1900, 

and gage heights were read until February 28, 1903, but the results 

were so conflicting that the station was abandoned. In July, 1903, a 

cable station was established by the commission about 2 miles above 

Nuevo Laredo, and on August 1, 1903, regular meter measurements 

and gage heights were started. The new gage heights are not comparable with the old. The station is about 670 miles below El Paso.

The river bed at the new station is constantly shifting, and frequent 

discharge measurements are made to determine closely the daily discharge. The banks at the new station are not subject to overflow.

The observations at these stations have been made under the direction of the Mexican section of the International Water Commission 

(prior to July 1, 1910, International Boundary Commission).

Discharge measurements and gage heights for the years 1900 to 

1904, which had not hitherto been published by the United States 

Geological Survey, are given in Water-Supply Paper 248.

Discharge measurements of Rio Grande near Laredo, Tex., in 1910.

RIO GRANDE NEAR ROMA, TEX.

The station was established in 1900 by the International Boundary 

Commission. It is near Roma, Tex., 775 miles, by river, below 

El Paso.

The right bank is alluvial deposits and overflows in high water for 

a width of 250 feet. The overflow section is thickly covered with 

mesquite brush. The left bank is of hard material, and does not 

overflow.

The river bed is constantly shifting, and frequent discharge measurements are necessary to determine closely the daily discharge.

The highest recorded flood, September 16, 1904, marked 26 feet 

on the gage.

The observations at this section have been made under the direction 

of the Mexican section of the International Water Commission (prior to 

July 1, 1910, International Boundary Commission).

Discharge measurements and gage heights for the years 1900 to 

1904, which had not hitherto been published by the United States 

Geological Survey, are given in Water-Supply Paper 248..

EIO GRANDE NEAR BROWNSVILLE., TEX.

This station was established in 1900 by the International Boundary 

Commission. It is about 1 mile above Brownsville, Tex., and 

opposite Matamoros, Tamaulipas, Mex., and 900 miles by river below 

El Paso.

Between Roma and Brownsville there are many lagoons (old river 

beds) which take river water during moderate floods, and a large area 

overflows quite deeply in larger floods. Much of this water returns 

slowly to the river as the flood subsides, so that the flow passes 

Brownsville more uniformly than it passes Roma. Large quantities 

of water also leave the river entirely, reaching the Gulf of Mexico 

through channels remote from the Rio Grande. Local run-off, however, keeps the total water at Brownsville well up toward the combined flow of the San Juan and the Rio Grande at Roma. Both banks 

are alluvial and are just about level with high water. The right bank 

is protected by piling.

As the bed of the river is constantly shifting, frequent discharge 

measurements are made to determine closely the daily flow.

The observations at this station have been made under the direction 

of the Mexican section of the International Water Commission (prior 

to July 1, 1910, International Boundary Commission).
74 SUBFACE WATER SUPPLY, 1910, PART VIII.

Discharge measurements and gage heights for the years 1900 to 

1904, which had not hitherto been published by the United States 

Geological Survey, are given in Water-Supply Paper 248.

CLEAR CREEK BASIN. 

CLEAR CREEK NEAR CREEDE, COLO.

Clear Creek rises in the southeastern part of Hinsdale County, Colo., 

and flows in a general southeasterly direction to its junction with the 

Rio Grande in Mineral County. The creek is about 20 miles long.

The gaging station, which is located near the mouth of the creek, 

at the highway bridge at Texas Club House, about 20 miles above 

Creede, was established August 12, 1910, by the State engineer, and 

is maintained by the State.

The gage is a vertical staff bolted to the bridge abutment.

Measurements are made from the bridge or by wading above bridge. 

The measuring section at the gage is poor, but the wading section 

above is good.

The bed of stream is composed of gravel and small bowlders, and is 

not liable to shift. The record at this station gives the entire flow 

contributed by Clear Creek to the Rio Grande.

SOUTH FORK OF BIO GRANDE. 

SOUTH FORK OF RIO GRANDE AT SOUTH FORK, COLO.

The South Fork of the Rio Grande, a stream about 15 miles long, 

rises near Summitville, in Rio Grande County, and flows northward 

to its junction with the main stream at South Fork.

The gaging station, which is located at highway bridge half a mile 

west of South Fork, was established by the United States Geological 

Survey May 17, 1909, as a temporary station, a reference mark being 

put on lower chord of bridge. It was reestablished by the State 

engineer August 9, 1910, since which time a record of gage heights 

has been kept.

A slope gage is bolted to downstream side of right abutment of 

highway bridge.

Measurements are made from bridge or by wading above the 

bridge. The measuring section at bridge is poor, but the wading 

section above is good.

The bed of the stream is of gravel, cobbles, and bowlders, and is 

not liable to shift.

CONEJOS RIVER BASIN. 

CONEJOS RIVER NEAR MOGOTE, COLO.

Conejos River, the most important tributary of the Rio Grande in 

Colorado, rises on the eastern slope of the San Juan Range, which 

forms the western boundary of Conejos County. It first flows south-' 

eastward, but at the town of Conejos bends northeastward and enters 

the Rio Grande below the mouth of Trinchera Creek.

The gaging station, which was established March 21, 1907, replacing the station formerly maintained about 4 miles below, is locatod 

at a private highway bridge on Jacob's ranch, about 16 miles above 

Antonito, Colo., in T. 33 N., R. 6 E., New Mexico principal merdian. 

It is above every important diversion for irrigation and below all the 

principal tributaries except the San Antonio.

The datum of the chain gage, which is on the bridge, has not been 

changed since the station was established. This gage is at the same 

datum as the rod gage used by Antoine Jacob during 1905 and 1906. 

The gage heights for these years have been furnished to the United 

States Geological Survey by him from his private records. Discharge 

measurements are made f rdm the highway bridge.

The data obtained at this station show the amount of water available for irrigation.
WESTERN GULF OF MEXICO. 79

Water taken from the Conejos by numerous ditches below the station is used to irrigate 70,000 to 80,000 acres of land. The basin 

above the station affords excellent opportunities for storage, none of 

which are utilized at the present time. It will be difficult to obtain 

additional water rights for irrigation along this stream.

The river is covered with ice for three or four months during the 

winter season. The stream bed is strewn with cobblestones and 

bowlders, and the water has a comparatively high velocity at all 

stages, making conditions unfavorable for accurate measurement. 

Eddies around the crib piers of the bridge also introduce uncertainty 

in the results.

SAGUACHE RIVER NEAR SAGUACHE, COLO.

Saguache River rises among the peaks of the Continental Divide in 

the western part of Saguache County, Colo., flows northeasterly about 

25 miles, then turns and flows southeastward into San Luis Park. In 

times of flood its waters may reach San Luis Creek but all the normal 

and high-water flow is taken by irrigation canals.

A gaging station was established in 1910 by the Stark-Hagadorn 

Irrigation Co. at a dam site 9 miles above Saguache. Practically no 

flow is contributed to Saguache River below this station. Some irrigation is carried on above the station.

Two gages are used a Bristol automatic and a vertical staff 

gage set in the automatic gage well. Both gages are at the same 

datum, which has not changed during the year.

Measurements are made from a foot log or by wading at the gauge. 

The section is good. The bed of the stream consists of sand and 

gravel, with a few small cobbles, and is not liable to shift.

The following record was furnished by the State engineer of Colorado through the courtesy of the Stark-Hagadorn Irrigation Co.:

ARROYO HONDO BASIN.

ARROYO HONDO NEAR ARROYO HONDO, N. MEX.

Arroyo Hondo arises in the eastern part of Taos County, N. Mex.,

and flows southeastward to its junction with the Rio Grande. The 

valley through which it flowe. is from one-half to three-fourths of a 

mile wide for about 4 miles, then alternately contracts and opens at

short intervals. Through the greater part of the stream's course the

valley lies fully 500 feet below the level of the surrounding country. 

The gaging station was established April 8, 1910, at the highway 

bridge at John Dunn's ranch 200 yards above the mouth of the stream 

and below all tributaries and diversions. It is 15 miles from Servilleta, the nearest railroad point, and 14 miles from Taos. A slope 

rod gage is fastened to left bridge abutment. Gage readings are 

taken gratis by John Dunn.

BIO TAGS BASIN. 

DESCRIPTION.

Rio Taos is formed by three principal streams Rio Pueblo de 

Taos, Rio Fernando de Taos, and Rio Grande del Rancho.

Rio Pueblo de Taos enters Taos Valley on the north, a short distance above the ancient Indian pueblo of Taos. Its principal tributaries are Rio Lucero and Arroyo Seco, but it receives only flood 

waters from these streams, their normal flow being used for irrigation.

Rio Fernando de Taos issues from a narrow canyon about 3£ miles 

above Taos. It furnishes water for three or four small ditches.

Rio Grande del Rancho, which lies farthest south, has one tributary Rio Chiquita which joins it 2 miles below the point where it 

enters the valley. During the irrigating season the stream carries 

little if any water.

Below Cordova the Rio Taos flows through a canyon to its junction 

with the Rio Grande.

The Taos Range to the east is well timbered with pine and spruce 

and contains valuable mineral deposits.

EIO PUEBLO DE TAOS NEAR TAOS, N. MEX.

A station was established April 7, 1910, about 2 miles upstream 

from the Indian pueblo of Taos and 200 yards upstream from the 

uppermost irrigation diversion. It is below all mountain tributaries.

A vertical rod gage was located on the left bank but was destroyed 

before July 12. A new gage was installed in the same position 

October 12, with datum 0.27 foot lower. No regular observer was 

employed and only occasional gage readings were obtained until 

December 19, when a Bristol automatic gage was installed at the 

datum of the second staff gage.

RIO PUEBLO DE TAOS AT LOS CORDOVAS, N. MEX.

This station was established April 6, 1910, about 100 feet downstream from the mouth of Rio Grande del Rancho and Arroyo Seco 

and about 1 mile below the mouth of Rio Lucero. It is just 

below A. J. Anderson's grist mill and a short distance northeast of 

Los Cordovas. The readings are taken from a vertical rod gage 

located on the right bank.

SANTA FE CHEEK BASIN. 

 DESCRIPTION..

Santa Fe Creek rises on the range east of Santa Fe and flows westward over high plains to join the Rio Grande. In the mountains 

at the head of the creek are two small lakes which may be considered 

typical of those at the headwaters of other streams flowing toward 

the Rio Grande. The elevation of these lakes is about 11,000 feet. 

Between Santa Fe and Cieneguilla the stream runs through a valley 

with gradually sloping sides. At Cieneguilla it enters La Bajada 

Canyon, which is deep and narrow as far as the town of La Bajada; 

below this is a broader valley with a gentle slope to the left and the 

edge of the mesa to the right. This valley continues almost to the 

mouth of the creek.

SANTA FE CREEK AT MONUMENT ROCK, NEAR SANTA FE, N. MEX.

This station is located 7 miles above Santa Fe, at Monument 

Rock a large, conspicuous bowlder near the creek. The gage was 

established August 27, 1910, by an engineering party temporarily in 

that vicinity. Several gage readings were taken daiJy and numerous 

discharge measurements made. The station is about 4 miles above 

that established May 12, 1910, near the Santa Fe Water & Light Co.'s 

ditch. No important tributaries enter between the stations.

SANTA FE CREEK NEAR SANTA FE, N. MEX.

This station, which was established May 31, 1907, to determine 

the amount of water available for irrigation and storage, is located 

at the Don Gaspar Avenue bridge in the city of Santa Fe.

The gage datum was changed on August 13, 1908, and again on 

August 22, 1908. Results obtained at this station have been very 

unsatisfactory owing to the torrential character of the stream, the 

shifting nature of the bed, and the inadequate number of discharge 

measurements.

Discharge measurements are made from the downstream side of 

the bridge.

No important tributaries except intermittent streams enter below 

the station. The drainage area at the station is about 40 square 

miles, and at the mouth of the river it is about 300 square miles.

The reservoir for the Santa Fe municipal supply is situated in the 

canyon above the station and a water-power plant of 100-horsepower 

capacity is used to develop power for lighting. Very little water is 

diverted for irrigation above the station. One small ditch takes 

water out just above. In the canyon 8 miles above Santa Fe is a 

reservoir site where 10,000 acre-feet can be stored.

Ice is usually to be found in the stream during the winter months, 

though the flow is very small during that period. The low-water 

flow is regulated to some extent by the waterworks reservoir above.

On May 12, 1910, the station was moved to a point 3£ miles above 

Santa Fe, about three-fourths of a mile above the Santa Fe Water & 

Light Co.'s reservoir and about 1,000 feet below the intake of the 

company's ditch. A vertical rod gage and a cable were installed.

SANTA FE WATER & LIGHT CO. S DITCH NEAR SANTA FE, N. MEX.

The Santa Fe Water & Light Co.'s ditch diverts water from Santa 

Fe Creek about 3 miles above Santa Fe.

A vertical gage rod was established on the ditch June 7, 1910, at 

a point about one-fourth mile below the intake and about 600 feet 

above the cable station on the creek. A gage height record was 

obtained for June 7 to 30.

BIO PUERCO BASIN. 

DESCRIPTION.

Rio Puerco rises in the mountains in the southern part of Rio 

Arriba County, N. Mex., and flows in a general southerly course about 

100 miles across Sandoval, Bernalillo, and Valencia counties to its
WESTERN GULF OF MEXICO.

junction with the Rio Grande near La Joy a. It drains a large area 

but is dry at its mouth during the winter and early spring. It holds 

a constant stream as far south as Casa Salazar, a point southwest 

of Jemez, and from there on the water is caught during floods, by 

brush dams which wash away each winter and must be rebuilt in 

the spring.

San Jose River, the principal tributary of Rio Puerco, or, as known 

at the headwaters, Bluewater Creek, enters from the west. This 

river must discharge an enormous amount of flood water, for its 

drainage area is large, but normally it is a small stream which flows 

constantly at all seasons for some 3 miles below Laguna, where in 

summer it evaporates. Brush dams are used also at some points 

on this creek.

RIO PUERCO AT RIO PUERCO, N. MEX.

This station was established September 7, 1910, at the Atchison, 

Topeka & Santa Fe Railway bridge crossing Rio Puerco between the 

railway stations of Pavo and Rio Puerco. It is a short distance 

below the mouth of San Jose Creek.

A Friez automatic gage is fastened to a timber retaining wall on 

the left bank.

MIMESES RIVER BASIN. 

DESCRIPTION.

Mimbres River rises on the western slope of the Mimbres Range 

in the extreme northeastern part of Grant County, N. Mex., and takes 

a general southeasterly course to the western part of Dona Ana 

County, where its waters are lost.

Cameron Creek, which fjows through the Fort Bayard military 

reservation, may send its flood waters to the Mimbres.

MIMBRES RIVER NEAR FAYWOOD, N. MEX.

The station, which is located about 6 miles southeast of Faywood 

Hot Springs and 10 miles from Faywood station, on the Silver City 

branch of the Santa Fe Railway, was established April 23, 1908, to 

determine the amount of water available for storage.

No important tributaries enter in the vicinity of the station, though 

many intermittent tributaries come in both above and below. The 

drainage area is about 450 square miles.

Some water is used for irrigation in the Mimbres Valley below the 

station, but as this is primarily a flood stream and as storage has not 

been provided, such irrigation is uncertain. By storing the flood 

water and cutting off the underflow at the Rio Mimbres dam site it 

will be possible to reclaim several thousand acres of land along this 

stream.

The gage is located about 400 feet below the proposed Rio Mimbres reservoir dam site. The gage datum was lowered 4 feet on 

July 8, 1909, and was afterwards raised 3 feet on August 13, 1909, 

when a Friez automatic gage was installed 200 feet above the chain 

gage on the right bank.

The flow of the stream at the gaging station is not usually affected 

by ice during the winter months. As the channel shifts a great deal, 

frequent measurements are necessary at high and medium stages to 

obtain the best results. Measurements during high stages are made 

from a cable 1,000 feet below the automatic gage.

CAMERON CREEK BASIN. 

CAMERON CREEK AT FORT BATARD, N. HEX.

This station, which was established on January 17, 1907, at the 

request of the United States Forest Service, to obtain data concerning 

flood run-off, is located near the pumping station at Fort Bayard,
WESTERN GULF OF MEXICO. 103

N. Mex., a United States Army post. The gage, a vertical rod, is a 

short distance above the crest of an old masonry dam, which was 

used to check the underflow of the creek.

For the greater part of the year the flow comes from springs, and 

amounts to less than 1 second-foot. Stevens Creek enters about 2 

miles above this station.

The intake for the water supply of the post is above the station, 

and a little water is also diverted above for garden irrigation. The 

flood waters of this stream can probably be stored in natural depressions in the vicinity, which will make excellent reservoir sites. These 

can be supplied by feeder canals.

Ice does not appreciably affect the flow of the stream at this point. 

The channel has filled up with sediment above the dam, which doubtless has some effect on low-water measurements. The channel is 

probably permanent for measurements taken at higher stages. 

Unfortunately no high-water measurements have yet been made. 

Measurements are made by wading.

No change has been made in the datum of the gage during the 

maintenance of the station. Gage observations have been taken 

gratis by Sergt. T. J. McBurney, United States Army.

STEVENS CREEK NEAR FORT BATARD, XT. HEX.

This station, which was established January 17, 1907, at the request 

of the United States Forest Service, is located one-fourth mile above 

the Fort Bayard planting station of the Forest Service, 3 miles north 

of Fort Bayard.

The records furnish valuable information concerning normal and 

flood run-off. The station is situated about 2 miles above the junction of this stream with Cameron Creek.

The normal flow of this creek is very small, but for short periods 

during floods it occasionally carries a large flow, which can probably 

be stored. The intake for the water supply of the planting station 

is above the gage.

The records of this station are little, if any, affected by ice. The 

results obtained have not been very satisfactory, owing to the small 

number of discharge measurements, none of which were taken when 

there was any considerable flow in the stream.

No change has been made in the datum of the gage since the establishment of the station.

BIO TULAKOSA BASIN. 

RIO TULAROSA AT MESCALERO, N. MEX.

Rio Tularosa rises in the southwestern part of the Mescalero 

Apache reservation, N. Mex., flows northwestward to a point 2 

miles beyond the agency, then turns and flows southwestward about 

18 miles to the flats in the northeastern part of Dona Ana County.

The station was established November 27, 1910, at a wagon bridge 

crossing the stream just inside of the gate into an alfalfa field about 

one-fourth mile below the Indian agency. It is about 300 yards 

below the ditch which carries the tail water from the agency power 

house. A vertical rod gage is fastened to upstream end of left 

abutment.

The following discharge measurement was made by J. B. Stewart:

November 27, 1910: Width, 5.2 feet; area, 4.7 square feet; gage height, 1.82 feet; 

discharge, 13.6 second-feet.

BIO LA LTTZ BASIN. 

RIO LA LUZ NEAR LA LUZ, N. MEX.

Rio La Luz, a stream about 2 miles long, rises in the southwestern 

part of the Mescalero Apache reservation and flows westward 

through a canyon to La Luz, in Dona Ana County. Its principal 

tributary is Fresnal River.

This station, which was established August 13, 1910, is located 

about 200 feet above Ranger's cabin, which is 1 mile above La Luz. 

It is about 200 feet above head of the development ditch, the uppermost diversion of any importance, arid half a mile below the mouth

PECOS RIVER BASIN. 

DESCRIPTION.

Pecos River, the largest tributary of the Rio Grande, rises on the 

east side of the Santa Fe Range in northern New Mexico, flows south 

through eastern New Mexico, then southeast through southwestern 

Texas, and unites with the Rio Grande about 400 miles (by river) 

below El Paso. Except for some of the upper tributaries, the 

branches of the Pecos are intermittent, carrying large floods at times. 

From source to mouth the river is about 800 miles long, and the total 

drainage area includes more than 32,000 square miles, of which 23,000 

are in New Mexico and 9,000 in Texas.

The upper Pecos flows as a typical mountain stream through 

narrow valleys and deeply cut gorges, but below Fort Sumner the 

canyon-like walls are replaced by low hills, and when the river 

reaches Roswell the gradation from the flood plains to the prairie is 

imperceptible. Arroyos and gulches are rare, and canyons are practically unknown. The mountain tributaries of the upper Pecos rise 

at elevations of about 11,000 feet; at Santa Rosa, N. Mex., the elevation of the river is 4,600 feet; at Roswell, 3,500 feet; at Pecos, Tex., 

2,550 feet; and at the mouth of the stream it is 1,000 feet.

The main Pecos may be said to be formed by the junction of the 

Gallinas with the upper Pecos at La Junta, N. Mex. The most 

important tributaries below this point and above Roswell are the 

Agua Negra and the Agua Negra Chiquita, which enter just above 

Puerto de Luna. Except for small springs, no important tributaries 

enter along this stretch, but some of the dry gulches and arroyos 

occasionally carry large quantities of flood water. Among the most 

important of the lower tributaries are the Hondo, Rio Felix, the 

Penasco, Seven Rivers, and Black River.

It is rather a striking fact that the Pecos receives practically no 

tributaries from the east, probably because of the pervious character 

of the soil of the Staked Plains, upon which there is no surface drainage system. The water sinks into limestone rocks and establishes 

an underground drainage.

The condition of the Pecos basin may be characterized roughly as 

follows: Merchantable-timber land, 1,300 square miles; woodland, 

2,400 square miles; 300 square miles of burnt and cut over land; and 

the remaining area of about 27,000 square miles is open and sagebrush land.

The rainfall along the Pecos in New Mexico ranges from 20 to 25 

inches in the mountainous sections, as above Las Vegas and at 

Cloudcroft, to about 15 inches in the plains country, or in the vicinity 

of Roswell and Carlsbad. Through Texas the rainfall is light, the 

annual average being about 12 inches.
108 SURFACE WATER SUPPLY, 1910, PART VIII.

During the winter period the flow of the Pecos is supplied mainly 

by springs. The river has been known to go dry in the neighborhood 

of Colonias, N. Mex. (See PI. Ill, A)

Considerable ice forms on the upper Pecos, and heavy snows are 

common. In the vicinity of Santa Rosa and Fort Sumner thin ice 

and slush ice are in evidence during a part of the winter. Lower 

down the valley there is an occasional light snow, which disappears 

very quickly, and at times there is thin ice along the edges of the 

river. In the lower end of the valley the climate is mild. The rainfall comes mainly in the summer months, in the form of showers, and 

is variable and uncertain.

Irrigation in New Mexico has reached its highest stage of development in the lower Pecos Valley, the irrigated district beginning a 

short distance above Roswell and continuing into Texas. Thousands 

of acres are under cultivation, and a wisely planned system of reservoirs and canals is in operation. The surface waters have been 

greatly augmented during the past few years by numerous artesian 

wells. Above this fertile belt comparatively little farming is done; 

below it irrigation is carried on only in a small way, as the return 

seepage water contains, unfortunately, so much alkali that it is 

unsuitable for irrigation.

The recently completed Carlsbad and Hondo projects of the Reclamation Service provide for the irrigation of 20,000 and 10,000 acres, 

respectively, while the proposed Urton Lake project, which is to be 

relinquished by the Reclamation Service in favor of a Carey Act 

project, will result in the irrigation of about 60,000 acres in the 

vicinity of old Fort Sumner, N. Mex.

Numerous reservoir sites are to be found along the Pecos and its 

tributaries. Among the reservoirs now in operation may be mentioned Lake McMillan on the Pecos, and the Hondo reservoir on 

Hondo River. Urton Lake, a natural depression in the vicinity of 

Fort Sumner, will have a storage capacity of 190,000 acre-feet. It 

is to be supplied by a feeder canal from Pecos River. Because of 

the large amount of silt carried by this stream the prevention of its 

deposition must be taken into account and provided for in the construction of reservoirs.

On account of its long periods of low water, this stream does not 

offer many favorable opportunities for the development of power. 

At present there are no water-power plants of any importance in 

operation in the basin, except a public-utility plant of about 300 

horsepower at Carlsbad, N. Mex. Later there may be some power 

development in connection with irrigation projects.

The records along this stream are very fragmentary and most of 

them were taken within the last five or six years. From them it 

would appear that 1903 was a very low year and 1905 an unusually 

high one.

PROGRESSIVE DISCHARGE MEASUREMENTS BETWEEN RIBERA AND FORT

SUMNER, N. MEX.1

In order to ascertain the amount of water sinking in the bed of the 

Pecos and to determine whether it reappears farther down the valley, 

a series of progressive discharge measurements were made March 

9-16, 1910, between Ribera and Fort Sumner. (See fig. 1.)

FIGURE 1. Map of upper part of Pecos River basin.

The trip was made more or less continuously along the river from 

Ribera to Colonias, where it was found impracticable to follow 

the river, and between Colonias and Santa Rosa the journey was 

made across the mesa west of the river. From Santa Rosa to a point 

about 4 miles below Puerto de Luna the course of the river was followed, after which it was not touched again until a point about 5 

miles above Fort Sumner was reached. For nearly the entire dis-

tance the river flows through a series of red sandstone strata, ranging 

in thickness from a few feet to several hundred feet and overlain in 

the upper portions of the section by gypsum and limestone beds. 

The limestone and gypsum strata dip to the east, and at Colonias 

and also in the section below Santa Rosa are in turn overtopped by 

thick layers of sandstone interstratified with thin layers of gypsum.

The river bed throughout its course consists of sand, gravel, and 

bowlders. Quicksand is common. The bowlders appear in the 

more rapid stretches of the stream and the sand in the quieter 

stretches. For the most part the valley lies between steep bluffs, 

about 500 feet high, back of which is mesa land that is in places so 

cut by canyons and gulches that it is difficult to cross. The canyons 

carry water only after the heavier rains.

The mesa is covered with a thin coating of soil supporting a scant 

growth of gramma grass and scattering bunches of low pines and oak. 

It is practically uninhabited, for it is too dry for farming and even 

water for domestic purposes must be brought from the river. It is 

used principally for sheep and goat range, and for this use it seems 

best adapted. The uplands, however, include tracts of open level 

country which would be admirably suited to irrigation were water 

available. The feasibility of getting water to this elevation above 

the river can be determined only by detailed surveys, but it is rather 

doubtful because of the great length of ditch necessary and the 

rugged and stony character of the country through which it would 

have to be constructed.

Between San Miguel and La Cuesta the valley is about three-fourths 

of a mile wide and is irrigated in a crude way by water taken from the 

river. The farms are divided into small tracts and the labor is done 

largely by hand. The principal crops are oats, corn, beans, and Mexican peas.

Between La Cuesta and Anton Chico the river flows through a narrow box canyon affording a number of good sites for reservoirs. 

Between Anton Chico and Colonias the valley broadens again, 

the bluffs becoming less precipitous. A small area is irrigated in 

each of these places. From Colonias to Santa Rosa the valley is 

narrow. At Santa Rosa it broadens out considerably, narrows again 

about 5 miles below, and then gradually broadens and becomes 

shallower until "at Fort Sumner the water flows among sandbars and 

the banks slope gradually back to the uplands.

Gallinas River, which enters the Pecos near La Junta, is the principal tributary in this stretch and the only one that carries a perennial 

flow. This flow, however, is small, and is derived from a series of 

springs about 8 miles above the mouth of the Gallinas. There is no 

regular flow of this river above the springs. The mouth of the Gal-
WESTEBN GULF OF MEXICO. Ill

linas was not visited during this investigation. Residents, however, 

stated that little or no water was flowing there.

The discharge measurements except the one 4 miles below La Cuesta 

were taken successively during a journey down the stream. The 

La Cuesta measurement was made while going from Anton Chico to 

San Mguel. The river in this vicinity is almost inaccessible for a 

stretch several miles in length. All measurements were made at 

selected sections and are believed to be accurate. The following is a 

list of discharges:

The water of the river probably begins to sink near Anton Chico, 

but the diminution of flow does not become noticeable until the 

stream reaches La Cueva. Between La Cueva and Colonias the 

stream crosses strata of porous limestone, into which it gradually 

disappears. At normal stages the water disappears a mile or more 

above Colonias. Three days before the measurement was made no 

water was passing Colonias, but a day or so before these measurements were begun there was a small rise in the river caused by melting snows in the lower mountains. The measurements below Santa 

Rosa were made in advance of the rise. The above data will be 

used on the assumption that the river was fairly constant in stage 

during measurements from Ribera to Colonias and from Santa Rosa 

to Fort Sumner.

The difference between the discharge at the point 4 miles below 

La Cuesta and at Colonias is 69 cubic feet per second. As 

usually no water sinks below Colonias, this 69 second-feet must 

be the normal amount of water disappearing. The amount reaching 

the river 6 miles below Santa Rosa at normal stage is 85 to 90 secondfeet. This would indicate an increase of about 20 second-feet over 

the amount sinking above Santa Rosa. An inspection of the topographic sheets of this section indicates that the waters sinking above 

Colonias reappear in the region of Santa Rosa. This conclusion 

has been strengthened by observations across the mesa between
112 SURFACE WATER SUPPLY, 1910, PART VIII.

Colonias and Santa Rosa. A chain of sinks, or so-called dry lakes, 

extends from a point near the place of sinking to the flowing lakes 

at Santa Rosa (PI. Ill, B). Some of these sinks are smooth depressions covering several acres; others are holes 50 feet in diameter. 

The latest formed depressions have vertical sides and range in depth 

from a few feet to a hundred feet or more. Erosion gradually rounds 

off the edges and fills the middle until there remains only a pot-shaped 

depression. Some of these depressions have been formed since the 

settlement of the country. It is said that a man living upon the 

mesa found one morning in front of his house a hole 60 feet in diameter 

and about 150 feet deep. A story is also told of a suddenly formed 

depression that filled with water and was claimed by two men. 

The controversy was taken to court, but before a decision was rendered the water disappeared, leaving only a dry hole.

The lakes near Santa Rosa are 200 to 300 feet in diameter, and 

some of them are reported to have been sounded to a depth of about 

250 feet. They receive no surface drainage, but each yields a constant 

outflow of several second-feet. The surface of these lakes is only a 

few feet above the river and is 300 to 400 feet below the level of the 

sink holes on the mesa. The water is heavily charged with gypsum 

and gives off a "gyppy" odor.

These sinks afford conclusive evidence of solution in the gypsif erous 

beds, and the course of their succession, leading from the place 

where the river sinks to the point where the water reappears in the 

lakes, forms strong presumptive evidence that underground passages 

are followed by the water between those points. The incident mentioned above, in which a depression formed by a cave-in filled with 

water, also affords evidence of underground passage. In this case it 

is reasonable to conclude that the cave-in choked some subterranean 

watercourse, thus forcing the water up into the depression until it 

acquired sufficient head to reopen its channel, when the pent-up 

water in the depression sank away.

As no surface water enters the stream between Santa Rosa and 

Colonias the increase of 20 second-feet of the discharge at Puerto de 

Luna over that at La Cuesta must also come from some subterranean 

source. Part of this may be derived from the sinking of the Gallinas 

above the springs. The remainder can probably be accounted for 

as ground water.

PECOS RIVER AT COWLES, N. MEX.

This station, which was established March 9, 1910, is located 

about three-fourths of a mile below Cowles post office, 13 miles above 

Pecos, about 20 miles northeast of Glorieta, a station on the Atchison, 

Topeka & Santa Fe Railway, and 24 miles by trail from Santa Fe.

PECOS RIVER NEAR FORT SUMNER, N. MEX.

The station, which was established on June 12, 1904, to determine 

the amount of water available for the Urton Lake project of the 

United States Reclamation Service, is located at a place known as 

Arenosa, about 12 miles northwest of old Fort Sumner, N. Mex., 

and 4 miles upstream from Fort Sumner, a station on the Belen cutoff of the Atchison, Topeka & Santa Fe Railway, and is near the
WESTERN GULF OF MEXICO. 119

site of the proposed diversion dam and a few miles below Arroyo 

Salada. The nearest post office is Fort Sumner.

All the tributaries for a long distance above and below the station 

are intermittent in character and only occasionally carry large 

amounts of water. The drainage area above the station is about 

5,300 square miles.

Some irrigation is practiced along the bottom lands at various 

localities above the station, but not enough to materially affect 

the flow of the stream. The proposed Urton Lake project will divert 

a considerable portion of the stream flow at this point.

Slush ice sometimes forms at this station, and thin ice forms 

along the edges of the river, but results are not greatly affected by 

the ice conditions.

On July 5, 1905, tjie station was moved downstream and a new rod 

gage established at the present datum. Otherwise there had been 

no change in datum.

On account of the extremely shifting character of the channel, 

it is impossible to make reliable estimates of discharge unless very 

frequent measurements are made. High-water measurements are 

made from a cable.

The station was discontinued February 28, 1910.

PECOS RIVER NEAR DAYTON, N. MEX.

This station, which was established March 24, 1905, has been 

maintained in connection with the Carlsbad irrigation project in New 

Mexico to determine the amount of water supplied by the river to the 

McMillan reservoir, and is located about 3 miles east of Dayton, 

N. Mex., about 6 miles above the dam of the reservoir, and approximately 100 feet downstream from the mouth of Penasco River.

The original rod gage was washed out on September 6, 1905, and 

was relocated September 7, 1905, at a point about one-half mile 

upstream. Otherwise there has been no change in gage datum. 

Fair results can be obtained at this station if discharge measurements 

are taken at frequent intervals. This station was transferred March 

31, 1908, to the United States Reclamation Service, and since then 

they have made the discharge measurements. Discharge measurements are made from a cable located about 100 yards below the new

Considerable irrigation is practiced in the vicinity of Roswell, 

N. Mex., and opportunities for irrigation projects exist at various 

points above. The winters in this vicinity are comparatively mild 

and ice does not appreciably affect stream flow.

PECOS RIVER NEAR LAKEWOOD, N. MEX.

The station, which was established January 11, 1906, and transferred to the United States Reclamation Service March 31, 1908, is 

located 3 miles southeast of Lakewood and half a mile below the 

McMillan reservoir dam.

The present inclined rod gage was established May 8, 1906. It had 

been previously moved from its original location on February 8,1906.

Fair results can be obtained at this station if occasional discharge 

measurements are made at different stages. Discharge measurements are made from a cable located about one-fourth mile above 

the railroad bridge of the Eastern Railway of New Mexico.

The following discharge measurement was made by the United 

States Reclamation Service:

August 20: Gage height, 8.4 feet; discharge, 3,810 second-feet.

Daily gage height, in feet, of Pecos River near Lalcewood, N. Hex., for 1910.

WESTERN GULF OF MEXICO. 123

PECOS RIVER NEAR MOORHEAD, TEX.

The station, which was established by the International Boundary 

Commission in April, 1900, is near Moorhead, immediately above the 

high bridge of the Southern Pacific Railroad.

It is in the bottom of a canyon about 300 feet deep. Both 

banks of the stream are of rock, but the bottom is mud. The river 

here consists of a series of pools connected by rapids. The best 

pool was chosen for the station. Frequent discharge measurements 

are made to determine closely the daily discharge. The highest 

known flood occurred April 6, 1900, about two weeks before this 

gage was established. The water marks showed that it reached 

35.75 feet on the gage.

The observations at this station during 1910 have been made 

under the direction of the United States section of the International 

Water Commission (prior to July 1, 1910, International Boundary 

Commission).

GALLINAS RIVER NEAR LAS VEGAS, N. MEX.

The station, which was established August 13, 1903, and maintained primarily for the purpose of determining the amount of water 

available for diversion and storage in the San Guyjella Basin about 

6 miles northwest of Las Vegas, is located at Las Vegas Hot Springs, 

6 miles above Las Vegas, N. Mex.

The altitude of the station is about 6,700 feet. It is below all 

perennial tributaries. The drainage area above the station is about 

90 square miles; the total drainage area exceeds 600 square miles.

Very little water is diverted above the station, though practically 

all of the ordinary flow is used for irrigation in the valley below. The 

reservoir mentioned above has a capacity of about 40,000 acre-feet, and 

is to be used for the irrigation of 10,000 acres of land. It will be filled 

from the Gallinas, the Sapello, and other small streams in that vicinity. 

The flow of the stream at this point is not usually affected by it.

The gage was washed out on September 29, 1904, and replaced by 

the present rod gage on October 19, 1904, which is located about 

600 feet above the foot-bridge at the power house, from which high 

discharge measurements are made. Lower water measurements are 

made by wading. The zero of the new rod gage is 0.71 foot lower 

than that of the old one. Results at this station have been fairly 

satisfactory.

RIO HONDO BASIN. 

RIO RUIDOSO NEAR GLENCOE, N. HEX.

Rio Ruidoso rises on the eastern slopes of the Sierra Blanca in the 

western part of Lincoln County, N. Mex., and takes a general easterly 

course to its junction with Rio Hondo about 6 miles below San 

Patricio.

The gaging station, which was established August 17, 1910, is 

located 2| miles above Glencoe post office and about 2 miles above 

Eagle Creek. Numerous small ditches divert water for irrigation for 

about 16 miles above the station. Glencoe is about 50 miles east of 

Tularosa, and 12 miles south of Capitan, the nearest railroad point.

An inclined rod gage is fastened to the right bank about 50 

yards above the forest ranger station.

BIO SALADO BASIN. 

RIO SALADO NEAR GUERRERO, TAMAULIPAS, MEXICO.

The Salado is a torrential stream, entering the Rio Grande from 

the Mexican side about 60 miles below Laredo, or 730 miles by 

river below El Paso. The town of Guerrero is located on the Salado 

some 4 miles above its mouth, and the gaging station is 2 miles
132 SUBFACE WATER SUPPLY, 1910, PART VIII.

above the town. The gaging station was established in 1900 by 

the International Boundary Commission.

The river is a series of pools and rapids. The best pool available 

was chosen for the station. The banks are sandy clay, not subject 

to erosion. The bottom is mud. In low water the river is measured 

by wading among the rocks below the station. Frequent discharge 

measurements are made to determine closely the daily flow. The 

highest recorded flood, on June 16, 1903, gave 17.7 on the gage.

The observations at this station have been made under the direction of the Mexican section of the International Water Commission 

(prior to July 1, 1910, International Boundary Commission).

Discharge measurements and gage heights for the years 1900 to 

1904, which had not hitherto been published by the United States 

Geological Survey, are given in Water-Supply Paper 248.

Discharge measurements of Rio Salado near Guerrero, Tamaulipas, Mexico, in 1910.

BIO SAN JUAN BASIN.

BIO SAN JUAN NEAR SANTA ROSALIA RANCH, TAMAULIPAS, MEXICO.

The San Juan is a long torrential stream entering the Rio Grande 

15 miles below Roma and 790 miles by river below El Paso. Six 

miles above its mouth is the town of Camargo.

The station was. first established in 1900 near La Quemada, 12 

miles above Camargo, by the International Boundary Commission, but 

in time of heavy flood in the Rio Grande backwater reached the station, and on July 14, 1902, it was moved 6 miles farther upstream to 

its present location near Santa Rosalia ranch, Tamaulipas, Mexico. 

It is now above backwater.

The river bed at both stations shifts constantly and frequent discharge measurements have been made to determine closely the daily 

flow. Both banks a,re of sandy clay which are above high water and 

do not erode. The bottom of the river is sand which erodes slightly 

in flood.

Low water (no flow) was approximately zero on the gage prior to 

the flood of 1909, which swept away the station here. The channel 

was either scoured out at this time or the restored gage has not the
134 SURFACE WATER SUPPLY, 1910, PART VIII.

same datum as the old. No flow is now 8.5 on the gage. The 

highest recorded flood, on September 16, 1904, reached 27 feet on 

the gage.

The observations at both stations have been made under the 

direction of the Mexican section of the International Water Commission (prior to July 1, 1910, International Boundary Commission).

Discharge measurements and gage heights, 1900 to 1904, which had 

not hitherto been published by the United States Geological Survey, 

are given in Water-Supply Paper 248.

i There have been several floods on this stream during the past 10 days. High-water marks of recent 

date indicate a flood flow of around 1,000 second-feet. The Pintada Reservoir, 1J miles below the El Paso 

& Southwestern Railroad bridge, has water in it for the first time since it was built about 3 years ago. On 

Aug. 19 at 3 p. m., reservoir gage read 16.5 feet. It is stated that on Aug. 16 or 17 gage reading was 

about 20.0 feet. From the map it is estimated that when gage read 16.5 there were about 570 acre-feet in 

reservoir, and J. L. Campbell, engineer in charge of maintenance of way El Paso & Southwestern Railroad, 

states that the run-off from Pintada Canyon up to the latter part of August, 1910, had just filled the reservoir, the capacity being 1,300 acre-feet.
