SURFACE WATER SUPPLY OF WESTERN GULF OF 

MEXICO BASINS, 1912.

By W. W. FOLLETT, ROBEKT FoLLANSBEE, and G. A. GRAY.

AUTHORIZATION AND SCOPE OF WORK.

This volume is one of a series of 12 reports presenting results of 

measurements of flow made on streams in the United States during 

the calendar year 1912.

The data presented in these reports were collected by the United 

States Geological Survey under authority implied in the organic law 

(20 Stat. L., p. 394), which 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 structure, mineral resources, and products of the national domain.

The work was begun in 1888 in connection with special studies of 

water supply for irrigation. Since the fiscal year ending June 30, 

1895, successive sundry civil bills passed by Congress have carried the 

following item and appropriations:

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

for the investigation of underground currents and artesian wells, and for the preparation of reports upon the best methods of utilizing the water resources. 

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 to 1914, inclusive................................... 150,000

In the execution of the work many private and States organizations 

have cooperated, either (a) by furnishing data or (b) by assisting in 

collecting the data. Acknowledgments for cooperation under class 

"a" are made in connection with the description of each station 

affected, and for class "b" on page 14.

SURFACE WATEE SUPPLY, 1912, PAET VTH.

Measurements of stream flow have been made at about 2,000 points 

in the United States and also at many points in small areas in Seward 

Peninsula and the Yukon-Tanana region, Alaska, and in the Hawaiian 

Islands. During 1912 gaging stations were maintained by the Survey 

and the cooperating organizations at about 1,500 points, and many 

discharge measurements were made at other points. In connection 

with this work data were also collected 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 water-supply papers from time to time.

PUBLICATIONS.

For each calendar year there has been prepared a report embodying 

the stream-flow data collected during that year. An index to the 

reports containing stream-flow measurements prior to 1904 has been 

published as Water-Supply Paper 119. Circulars are also available 

giving complete lists of the gaging stations maintained by the Survey 

to date, and a list of the reports relating to the water supply of the 

country.

Prior to 1902 gage heights and discharge measurements were published in water-supply papers or bulletins and estimates of monthly 

discharge in annual reports; since 1902 both classes of data have been 

published in water-supply papers and they are now being published 

in 12 parts, as shown in the following table:

DEFINITION OP TERMS.

The volume of water flowing in a stream the "run-off" or "discharge" is expressed in various 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 discharge 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, 

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 

unit for the rate of discharge of water flowing in a stream 1 foot wide, 

1 foot 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
10 SUKFACE WATER SUPPLY, 1912, PART VIII.

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

regards time and area.

"Run-off (depth 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 unifoxmly distributed on the surface. It is used 

for comparing run-off with rainfall, which is usually expressed in 

depth in inches.

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

required to cover an acre to the depth of 1 foot. The term is commonly used in connection with storage for irrigation work.

so far as available, are given: Description of the station, list of discharge measurements, table of daily gage heights, table of daily 

discharge, table of monthly and yearly discharges and run-off. For 

stations located at weirs or dams the gage-height table is usually 

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
12 SURFACE WATER SUPPLY, 1912, PART VIII.

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 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, usually 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 gage. All gage heights affected by the presence 

of ice in the streams or by 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 tables of daily 

gage heights and daily discharge by plotting gage heights in feet as 

ordinates and discharge in second-feet as abscissas.

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 computation for the remaining 

columns, which are defined on pages 9 and 10, are based.

The base data presented in this report, unless otherwise stated in 

the description of the stations, have been collected by the methods 

commonly used at current-meter gaging stations and described in 

standard textbooks. Plate I shows typical gaging stations. Plate II 

shows current meters used in the work.

ACCURACY AND RELIABILITY OF FIELD DATA AND 

COMPARATIVE RESULTS.

The accuracy of stream-flow data 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 between discharge and stage.

Errors of the second class 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.

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.

Even though the monthly means for any station may represent 

with a high degree of accuracy the quantity of water flowing past 

the gage, the figures showing discharge per square mile and depth of 

run-off in inches may be subject to gross errors which result from 

including in the measured drainage area large noncontributing districts or omitting estimates of water diverted for irrigation or other 

use, and they should therefore be considered as only approximate, 

particularly for periods of irrigation or of low water. For these 

errors it is as a rule not feasible to make adequate correction.

In general the base data collected each year by the Survey engineers are published not only to comply with the law but to afford 

any engineer the means of examining and adjusting to his own needs 

the results of the computations. The table of monthly discharge is 

so arranged as to give only a general idea of the flow at the station 

and should not be Used for other than preliminary estimates. The 

determinations of daily discharge allow more detailed studies of the
14 SURFACE WATER SUPPLY, 1912, PART VIII.

variation in flow by which the period of deficiency may be determined.

It should be borne in mind that the observations in each succeeding 

year may be expected to throw new light on data already collected 

and published, and the engineer who makes Use of the figures presented in these .papers should verify all ratings and make such 

adjustments for earlier years as may seem necessary.

COOPERATION.

Special acknowledgments are due for financial assistance rendered 

by the State engineers of Colorado and New Mexico.

Through the efforts of Mr. J. A. French, State engineer of New 

Mexico, a suboffice was established at Santa Fe, and work was 

actively resumed in that State.

The stations on the lower Rio Grande and tributaries have been 

maintained by the International Boundary Commission, Wilbur 

Keblinger, commissioner on the part of the United States; Senor 

Fernando Beltran y Puga, commissioner on the part of Mexico; and 

W. W. Follett, consulting engineer on the part of the United States.

DIVISION OF WORK.

The field data for the Rio Grande drainage basin in Colorado were 

collected under the direction of Robert Follansbee, district engineer, 

by H. B. Waha.

The work in New Mexico was under the general supervision of 

Robert Follansbee. Beginning with August, the work was in the 

direct charge of G. A. Gray, assistant engineer, who was assisted by 

F. O'Brien, A. S. Kirkpatrick, E. L. Redding, J. E. Powers, R. L. 

Cooper, and C. J. Emerson.

The ratings and estimates for Colorado stations were made, and 

the completed data prepared for publication, under the direction of 

Robert Follansbee, by Raymond Richards, assisted by R. H. Fletcher.

The New Mexico ratings and computations were made by G. A. 

Gray, assisted by H. J. Dean.

STATION RECORDS. 

RIO GRANDE AT THIRTYMILE BRIDGE, NEAR CREEDE, COLO.

Location. In the Rio Grande National Forest, about 30 miles southwest of Creede, in 

sec. 13, T. 40 N., R. 4 W.; a short distance above mouth of jSquaw Creek.

Records available. June 18,1909, to November 30,1912.

Drainage area. 163 square miles (measured from topographic sheets).

Gage. Chain gage, 200 feet upstream from Thirtymile Bridge; washed out October 

5, 1911. The flood of this date changed the mouth of Squaw Creek, making it 

enter above the gaging station. For that reason, when the records were resumed 

April 8,1912, a vertical staff gage was established a quarter of a mile above the old 

location and above the new mouth of Squaw Cr«ek. The relation between the 

gages was not determined.

Channel. Apparently permanent.
BIO GRANDE. 15

Discharge measurements. Made from car and cable except during low stages, 

when they are made by wading.

Winter flow. Ice causes backwater during the winter months and records are discontinued.

Diversions. So far as known, no water is diverted above the station.

Artificial control. A short distance above the station the San Luis Valley irrigation 

district is constructing a large reservoir which will materially modify the flow of 

theriver when completed. During the low water of 1912, the operation of the reservoir gates controlled the flow somewhat.

Accuracy. Owing to the high altitude at this point it is possible that at certain 

seasons of the year the alternate melting and freezing may cause considerable 

diurnal fluctuations. For this reason the mean daily gage height taken from 

morning and evening readings may not represent accurately the true mean for the 

day. With this exception, conditions are favorable for accurate results, and 

altogether the records are considered good.

Cooperation. Station maintained in cooperation with Mr. J. C. Ulrich, of the San 

Luis Valley irrigation district, by whom the field data were furnished.

Gage. An automatic recording gage, the property of the State engineer. It ia 

referred to the same datum as the chain gage used previously.

Channel. Practically permanent.

Discharge measurements. Made from bridge.

Winter flow. River frozen over during winter months; ice causes backwater at 

gage.

Diversions. There are no court decrees for diversions from the Rio Grande above 

this station, but for diversions of 39 second-feet from tributaries. There are no 

reservoirs on the river between this station and the one at Thirtymile Bridge, 

but a large one is being built on Clear Creek, which enters between.

Accuracy. Good.

Cooperation. During 1912, this station was maintained by the State engineer in 

cooperation with the United States Forebt Service.

NOTE. The above records have been changed slightly from the State engineer's records to conform with 

the computing rules of the U. S. Geological Survey.

BIO GRANDE NEAB DEL NOBTE, COLO.

Location. At highway bridge in about sec. 30, T. 40 N., R. 5 E., 6 miles west of 

Del Norte, a short distance below the mouth of West Creek. From October 11, 

1889, to November 30, 1906, a station was maintained about 4 miles below the 

present station and just above Los Pinos Creek. The flow at the two points is 

not directly comparable, as a number of small tributaries enter between.
BIO GBANDE. 19

Records available. May 16,1908, to November 30,1912.

Drainage area. 1,400 square miles (furnished by State engineer).

Gage. Automatic recording gage, the property of the State engineer. The gage

is referred to the same datum as was the chain gage installed May 16, 1908. 

Channel. Slightly shifting. 

Discharge measurements. Made from bridge. 

Winter flow. Elver is frozen over during the winter months. 

Diversions. There are court decrees for diversions of 101 second-feet from the Rio

Grande between the Creede station and Del Norte, and for diversions of 162

second-feet from intervening tributaries. 

Cooperation. Complete records furnished by the State engineer.

BIO GRANDE AT EMBTTDO, N. MEX.

Location. At Santa Barbara Tie & Pole Co.'s bridge, a few hundred feet below the 

Denver & Rio Grande Railroad eating house, at Embudo, just above the mouth of 

the Box Canyon near sec. 27, T. 23 N., R. 9 E. Santa Barbara Creek, the nearest 

tributary, joins the Rio Grande about 3 miles above the station.

Records available. January 1, 1889, to December 31, 1903; September 8 to December 31, 1912.

Drainage area. Approximately 10,100 square miles.
EIO GEANDE.

Gage. Automatic recording. From January 1, 1889, to December 31, 1903, an 

inclined staff gage was used about 1,500 feet above the present gage. On September 8, 1912, an automatic gage was installed which was referred to a new datum. 

Old records do not show a change in datum from 1889 to 1903.

Channel. Subject to a change during flood stages, but fairly permanent at low stages.

Discharge measurements. By wading at low stages and from a cable during flood 

and medium stages.

Winter flow. Very slight ice affect during the winter months.

Diversions. A large part of the natural run-off is diverted for irrigation above this 

point.

Accuracy. The daily estimates of discharge in 1912 can only be considered fair.

BIO GRANDE NEAR BTTCKMAN, N. HEX. 1

Location. At the Denver & Bio Grande Railroad bridge 4 miles above Buckman 

2 miles below the Indian village of San Ildefonso, in about sec. 18, T. 19 N., 

R. 8 E. The nearest stream is Tesuque Creek, which enters near San Ildefonso. 

There is an arroyo just above the station.

Records available. February 1, 1895, to December 31, 1905; June 23, 1909, to 

December 31, 1912.

Drainage area. Not measured.

Gage. Automatic recording; installed in June, 1910. The original gage was located 

on the left bank 180 feet above the bridge. On March 30, 1904, a vertical staff 

gage was established at a. new datum at the bridge. The same gage was used 

when the station was reestablished in 1909. The datum of the present gage is 

the same as that of the gage established in 1904.

Channel. Somewhat shifting.

Discharge measurements. Made from car and cable 3 miles below the gage. 

No diversions or important tributaries between the two points.

Winter flow. Only slightly affected by ice.

Diversions. For many miles above the station many large and small ditches divert 

water for irrigation.

Accuracy. Prior to the flood in October, 1911, conditions were favorable for accurate results, but the flood caused considerable change which was not fully covered by field work. Thus the estimates previous to May 1, 1912, can not be considered better than fair. The records for the last part of 1912 can be considered 

good.

BIO GBANDE NEAB SAN MABCIAL, N. MEX.

Location. At the Atchison, Topeka & Santa Fe Railway bridge 1 mile south of 

San Marcial, in sec. 19, T. 7 S., R. 1 W. No important tributaries enter in the 

immediate vicinity of the station.

Becords available. August 8, 1889, to December 31, 1912.

Gage. Inclined staff gage established January 29, 1895, and carried away by flood in 

1896. A wire gage was established in its place at the same datum. This was soon 

abandoned and gage heights have since been measured with a graduated rod from 

the bridge-deck to the water surface. The gage datum of the inclined staff and 

wire gages is still used.

Channel. Sandy and very shifting. A number of bridge piers interfere with the 

accuracy of discharge measurements but not with gage height fluctuations.

Discharge measurements. Made from the downstream side of bridge.

Cooperation. Station.maintained since 1901'by the American section of the International Boundary Commission.

Discharge measurements of Rio Grande near San Marcial, N. Mex., in 1912.

BIO GEANDE. 33

BIO OBANDE ABOVE PRESIDIO, TEX.

Location. At the Haciendita, 9 miles above Presidio. From April, 1900, to September, 1905, the station was located at a point 9 miles above Presidio, 8 miles 

above the mouth of Rio Conchos, and about 200 miles below El Paso. Owing to 

the formation of a cut-off around the station it was necessary to abandon this site 

and, in September, 1905, the station was moved to a point 8 miles farther upstream. The cut-off formed in 1905 having since been closed and caving banks 

necessitating the abandonment of the new station, it was moved back to its 

original site on July 6, 1909, with a different gage datum from that of the first 

station.

Records available. April 4, 1900, to December 31, 1912.

Gage. An inclined rod fastened to posts sunk in the ground. Datum changed in 

September, 1905, and on July 6, 1909.

Channel. The bed is sandy and shifting. Both banks are fairly permanent and 

are inundated by extreme floods.

Discharge measurements. Made from a cable.

Cooperation. Station established and operated by the United States section of the 

International Boundary Commission.

BIO GRANDE BELOW PRESIDIO, TEX.

Location. 6 miles below Presidio and 7 miles below the mouth of Rio Conches, at 

the west end of the canyon section of the Rio Grande.

Records available. April 8, 1900, to December 31, 1912.

Gage. Inclined rod bolted to posts sunk into the ground. An additional flood gage 

is nailed to a tree at the gravel hills.

Channel. The bed is of shifting sand and is affected by a drainage channel called 

Alamos Creek, which enters 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 onto the gage until a flood in the river scours it out. The right bank is a 

rock bluff. The left bank is an alluvial deposit and overflows above a stage of 

about 13 feefc for a distance of 750 feet back from the stream to gravel hills.

Discharge measurements. From cable for stream proper and from boat for flooded 

left bank.

Cooperationi Station established and operated by the United States section of the 

International Boundary Commission.

Discharge -measurements of Rio Grande beloiv Presidio, Tex., in 1912.

BIO GRANDE AT BROWNSVILLE, TEX.

Location. About a mile above Brownsville, Tex., opposite Matamoros,Tamaulipas, 

Mexico; about 900 miles below El Paso.

Records available. April 29, 1900, to December 31, 1912, except March and 

April, 1903.

Gage. Vertical rod, fastened to fender pile on right bank.

Channel. Bed is sandy and shifting; both banks are alluvial deposits and are inundated by extreme floods only; right bank is protected by piling.

Discharge measurements. Made from cable.

Cooperation. Station established and operated by the Mexican section of the 

International Boundary Commission.

Between Roma and Brownsville there are many lagoons (old river beds) into which 

the river water flows during moderate floods, and a large area is overflowed deeply 

by the higher 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 discharge at Brownsville well up toward the combined flow of the San Juan and the 

Rio Grande at Roma.

SOUTH FORK OF BIO GRANDE AT SOUTH FORK, COLO.

Location. At highway bridge half a mile west of South Fork station, in sec. 34, 

T. 40 N., R. 3 E. No tributaries between the station and the mouth and none 

for several miles above.

Records available. August 9, 1910, to November 30, 1912. Also a number of discharge measurements made in 1909 by the United States Geological Survey.

Drainage area. 216 square miles (furnished by State engineer).

Gage. Chain gage established May 12, 1912, at the site of the original staff gage, but 

referred to a different datum. The original gage was washed out by flood October 5, 1911, and was replaced by an inclined staff gage at the railroad bridge at 

different datum, October 16, 1911. This gage was read until May 12, 1912.

Channel. Apparently permanent at the present location.

Discharge measurements. Made from bridge.

Winter flow. Ice causes backwater during the winter months.

Diversions. There are court decrees for diversions of 11 second-feet from South 

Fork above the station; none below.

Cooperation. Records furnished by the State engineer, by whom the station is 

maintained.

Discharge measurements of South Fork of Rio Grande at South Fork, Co to., in 1912.

54 SUBFACE WATER SUPPLY, 1912, PART VIII.

BIO ALAMOSA NEAR MONTE VISTA, COLO.

Location. In the Rio Grande National Forest, in sec. 2, T. 36 N., R. 5 E., 28 miles

southwest of Monte Vista; a short distance below the mouth of French Creek. 

Records available. September 29, 1911, to June 6, 1912. 

Drainage area. 91' square miles. (Determined from Forest Atlas.) 

Gage. Vertical staff. 

Channel. Data too few to be conclusive. 

Discharge measurements. Made from bridge 1 mile above gage during high

water and by wading at ordinary stages. 

Winter flow. No information available. 

Diversions. The station is above all diversions except a ditch and flume used

for hydraulic power at Terrace reservoir, which takes water half a mile above.

There are court decrees for diversions of 1,700 second-feet from Alamosa River

below the station. 

Accuracy. Conditions are favorable for fairly accurate results, and the estimates

are considered fair. 

Cooperation. Gage heights furnished by the United States Forest Service.

56 SURFACE WATER-SUPPLY, 1912, PART VIII.

BIO ALAMOSA NEAR LA JAB A, COLO.

Location. Just below the Terrace reservoir dam in sec. 14, T. 36 N., R. 6 E., and 

24 miles northwest of La Jara. There is no tributary within several miles.

Records available. April 18, 1909, to October 22, 1912.

Drainage area. 120 square miles (furnished by the State engineer).

Gage. Vertical staff located 1,000 feet below the dam.

Channel. Fairly permanent.

Artificial control. The Terrace reservoir has a total capacity of 17,000 acre-feet, of 

which 7,000 acre-feet were actually used during 1912. The reservoir eliminates 

daily fluctuations in stage and effects the high-water flow by reducing the crest 

somewhat and prolonging the high-water period. Since the records have been 

maintained the reservoir has had no effect on the low-water flow.

Diversions. There ara no court decrees for diversions above the station.

Cooperation. This station maintained by the San Luis Land & Irrigation Co. and 

the records furnished by Mr. John E. Field.

Daily discharge, in (fcond-feet, of Rio Alamo a near La Jara, Colo.,for 1909-1912.

SURFACE "WATER SUPPLY, 1912, PART 65

BIO HONDO NEAR ABBOYO HONDO, N. HEX.

Location. At highway bridge at Dunn's Hotel, 200 yards above the mouth of the 

stream, 1 mile west of Arroyo Hondo post office, near sec. 31, T. 27 N., B. 12 E. 

No tributary between station and mouth.

Records available. April 8, 1910, to December 31, 1912.

Drainage area. Not measured.

Gage. Vertical staff.

Channel. Shifting.

Discharge measurements. Made by wading at low stages and from a bridge at

Winter flow. Ice causes slight backwater during portions of the winter months. 

Diversions. None below but several diversions for irrigation are made above. 

Accuracy. Owing to the shifting character of the stream no estimates of discharge

were made the first part of 1912. The estimates during the last part of 1912 can

be considered good. 1 

Cooperation. -Gage heights furnished by the United States Reclamation Service.

before July 12, 1910. On October 12, 1910, a new gage was installed which 

was referred te a datum 0.27 foot lower than the original. The automatic gage 

was referred to the datum of the second gage.

Channel. Somewhat shifting, especially during high stages.

Discharge' measurements. Made by wading.

Winter flow. Ice causes backwater during the winter period.

.Diversions. None above station; several just below.

Accuracy. The estimates made in 1912 are fragmentary and can be considered 

only fair.

RIO LUCERO NEAR TAOS, N. HEX.

Location. Just above the head gate of the Seco ditch, at the mouth of the canyon, 

9 miles above Taos, in sec. 11, T. 26 N., R. 13 E. No important tributaries near 

the station.

Records available. December 17, 1910, to December 31, 1912, and fragmentary 

records from May to August, 1910.

Drainage area. 17 square miles.

Gage. Automatic recording; installed by the United States .Indian Service December 17, 1910, referred to the datum of vertical staff gage originally installed.

Channel. Somewhat shifting.

Discharge measurements. Made by wading.

Winter flow. Ice causes backwater at gage during the winter months.

Diversions. No diversions above the station. Records represent the natural run-off. 

Below the station water is diverted for irrigation.

Accuracy. Although the channel is somewhat shifting, it is probable that the estimates may be considered fair.

Cooperation. Gage-height record furnished by United States Forest Service and 

United States Indian Service.

PECOS RIVER BASIN. 

PECOS RIVER NEAR COWI.ES, N. MEX.

Location. At highway bridge in about Bee. 28, T. 18 N., R. 12 E., three-fourths 

mile below the old Cowles post office, 5 miles below the present Cowles post 

office, midway between Esperito Santo and Mora Creeks, about half a mile below 

the mouth of Willow Creek.

Records available. March 9, 1910, to December 31,1912.

Drainage area. Not measured.

Gage. Automatic recording. A gage of the Bristol type was installed June 5, 

1912, in place of a Friez automatic gage. These gages were referred to the same 

datum.
PECOS EIVEE BASIN. 85

Channel. Fairly permanent except during high water, when it may shift slightly.

Discharge measurements. Made from bridge during high water and by wading 

at ordinary stages.

Winter flow. Ice causes backwater during a portion of the winter months.

Accuracy. Conditions are favorable for accurate results, and the record should be 

reliable. The estimates previous to July 31, 1912, can be considered good, 

but on account of doubtful gage.heights estimates were not made after that date.

PECOS KIVER NEAR ANTON CHICO, N. HEX.

Location. About 1 mile below the settlement of Tecolotito, near see. 31, T. 12 N.

R. 17 E., about 3 miles northwest of Anton Chico, 1J miles below the mouth of

Tecolote Creek.

Records available. April 28, 1910, to December 31, 1912. 

Drainage area. Not measured. 

Gage. Automatic recording gage, which was moved three-fourths mile downstream

on May 15, 1911, and referred to a new datum. 

Channel. Apparently permanent. 

Discharge measurements. Made from car and cable during high water and by

wading at ordinary stages.

Winter flow. Ice causes backwater at times during the winter months. 

Accuracy. Owing to the character of the stream, the 1912 estimates can be considered

only fair. 

Cooperation. Gage heights furnished by V. K. Jones, Las Vegas, N. Mex.

PEOOS RIVER AT SANTA ROSA, N. MEX.

Location. At highway bridge at Santa Rosa, 1 mile above the mouth of Eio Agua 

Negra Chiquita, 6 miles above Canyon Pintada, in sec. 11, T. 8 N., E. 21 E. 

From May 5,1903, to December 31,1906, a station was maintained near the present 

one by the United States Reclamation Service, but the gage heights were referred 

to a different datum.

Records available. February 1,1910, to July 31,1911, and September 21 to December 31, 1912.

Drainage area. 2,780 square miles (measured on land-office map).

Gage. Chain gage.

Channel. Very shifting.

Discharge measurements. Made from bridge during high water and by wading at 

ordinary stages.

Winter flow. Practically no ice at this station.

Accuracy. Owing to the shifting character of the stream the estimates can not be 

considered better than fair.

PEOOS RIVER NEAR DAYTON, N. MEX.

Location. Three miles east of Dayton, in sec. 13, T. 18 S., R. 26 E., half a mile 

above the mouth of Penasco River.

Records available. March 24, 1905, to December 31, 1912.

Drainage area. Not measured.

Gage. Vertical staff. The original gage, which was located 100 feet below the mouth 

of Penasco River, was washed out September 6, 1905, and was relocated September 7, 1905, half a mile upstream. Datum unchanged since then.

Channel. Shifting during high water.

Discharge measurements. Made from car and cable.

Winter flow. Ice has little effect on the relation of gage height to discharge.

Diversions. The station is about 10 miles above the dam at the outlet of Lake 

McMillan, one of the reservoirs in the United States Reclamation Service Carlsbad project which will irrigate about 20,000 acres in the vicinity of Carlsbad.

Accuracy. Owing to the shifting character of the stream, the estimates can not be 

considered better than fair.

Cooperation. Gage heights and discharge measurements furnished by the United 

States Reclamation Service.

GALLINAS EIVEE NEAE LAS VEGAS, N. MEX.

Location. At Las Vegas Hot Springs, 6 miles northwest of Las Vegas, about sec. 1,

T. 16 N., R. 15 E. No tributaries between the station and Las Vegas, nor for

several miles above.

Records available. August 13, 1903, to May 31, 1912; December 1 to 31, 1912. 

Drainage area. 89 square miles (measured on topographic sheets). 

Gage. Vertical staff GOO.feet above the power-house foot bridge, installed to replace

the original gage, which was washed out September 29,1904; datum of new gage,

0.71 foot lower than that of the original gage. 

Channel. Somewhat shifting during high water. 

-Discharge measurements. Made from the footbridge during high water and by

wading at ordinary stages. 

Winter flow. Gage heights unaffected by ice as channel is kept open by the hot

springs. 

Diversions. A short distance above the station is a timber dam which forms a

pond from which ice is cut, but this dam does not control the flow in any way.

A small amount of water is diverted at this point by the Agua Pura Co., which

furnishes Las Vegas and the Santa Fe Railway with water. A mile below the

station is a dam which diverts the flood flow of the Gallinas to the San Guyjilla

basin. The fall of the river is so heavy that the gaging station is above the

influence of this dam. 

Accuracy. Although the river is somewhat shifting at this station, it is believed

that the estimates of discharge may be considered fair.

BIO SAN JUAN BASIN. 

RIO SAN JUAN NEAE SANTA ROSALIA RANCH, TAMAULIPAS, MEXICO.

Location. Near the Santa Rosalia ranch, 12 miles above the original station established in 1900 near La Quemada, 18 miles above Camargo, and 24 miles above the 

confluence of the Rio San Juan and the Rio Grande, which is about 15 miles 

below Roma, Tex.; removed to present site July 14, 1902, to obviate effect of 

backwater from the Rio. Grande during floods.

Records available. October, 1900, to December 31, 1912, except March and 

April, 1903.

Gage. An inclined rod spiked to posts and a tree.

Channel. The bed is sandy and shifts slightly in floods. Both banks are above 

flood level, are composed of sandy clay, and do not erode.

Discharge measurements. Made from cable.

Zero flow. Low water (no flow) was approximately zero on the gage prior to the 

flood of 1909, which swept away the station. The datum of the restored gage was 

8.5 feet above that of the original gage, but the datum was lowered about 10.5 

feet on May 25,1912.

Cooperation. Station installed and operated by the Mexican section of the International Boundary Commission.

INTERIOR BASINS IN NEW MEXICO.

MIMBEES EIVEE BASIN. 

MIMBRES RIVER NEAR FAYWOOD, IT. HEX.

Location. About 6 miles northeast of Faywood Hot Springs, in sec. 7, T. 20 S.,

B. 10 W., 10 miles from Faywood, a station on the Silver City branch of the

Atchison, Topeka & Santa Fe Railway. 

Records available. April 8, 1908, to December 31, 1912. 

Drainage area. Approximately 450 square miles. 

Gage. An automatic recording gage installed August 13, 1909, at a point 200 feet

upstream from the site of the chain gage originally installed. The chain-gage

datum was lowered 4 feet on July 8, 1909, and the datum of the recording gage is

about 3 feet higher than the new datum of the chain gage. 

Channel. Very shifting. 

Discharge measurements. Made from car and cable during high water and by

wading at other times.

Winter flow. Practically no backwater from ice at this point. 

Diversions. Some water is diverted for irrigation above and below the station; 400

feet above is the dam site of the Rio Mimbree reservoir, which is designed to

control the flood water for irrigation. 

Accuracy. The estimates made in 1912 can be considered fair.

Winter flow. Ice does not appreciably affect the flow at this station. 

Diversions. The intake for the Army post water supply is above the station and a

small amount of water is also diverted for garden irrigation. 

Accuracy. Owing to the shifting character of the stream and a lack of high-water

discharge measurements, no estimates of flow can be made. 

Cooperation. Gage heights furnished by Sergt. T. J. McBurney.
