« For the purpose of uniformity in the presentation of reports, a general plan has been agreed upon by

the United States Reclamation 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 natural drainage lines indicated by the parts 

of the report.

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.

6 SUEPACE WATER SUPPLY, 1911, PART VIII.

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 1913, inclusive..................................... 150,000

In the execution of the work various private and State organizations have cooperated. Acknowledgment for such cooperation 

is made on page 13, and also in connection with the description of 

each station affected by the cooperative work.

PUBLICATIONS.

Measurements of stream flow have been made at nearly 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 1911 gaging stations were maintained 

by the Survey and the cooperating organizations at about 1,500 points 

in the United States, 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 surface water-supply papers 

from time to time. A complete list of the gaging stations maintained 

by the Survey to and including 1910 and a list of the papers relating 

to the water supply of the country has been published by the Survey 

as Water-Supply Paper 280. An index to the reports containing 

stream-flow measurements prior to 1904 has been published as WaterSupply Paper 119.

For each calendar year there has been prepared a report embodying 

the stream-flow data collected during that year, which has been published either as a part of the annual report of the Director, as a bulletin, or as a water-supply paper, as shown by the following table:

DEFINITION OF 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 mav be denned as follows:
WESTEBtf GULF OF MEXICO.

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

a measure of 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 

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

regards time and area.

"Run-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.

An "acre-foot" is equivalent to 43,560 cubic feet, and is the quantity of water required to cover an acre to the depth of 1 foot. 

The term is commonly used in connection with storage for irrigation

work.

CONVENIENT EQUIVALENTS.

EXPLANATION OF DATA.

For each regular current meter gaging station the following data 

are given: Description of the 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.
WESTEKN GTJLF OF MEXICO. 11

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 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, 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 

periods.

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

corresponding to the observed gage heights as determined from the 

rating tables.
12 SURFACE WATER SUPPLY, 1911, PART VIII.

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 headed "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 page 9, 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 

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

the United States, 1909."

Plates I and II show the average run-off and rainfall in the United 

States as determined from the measurements of stream flow made 

by the Geological Survey and records of rainfall collected by the 

Weather Bureau. Plate III shows typical gaging stations, indicating 

the method of suspending the current meter; Plate IV shows current 

meters 1 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 runoff 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 also 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 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 AND ACKNOWLEDGMENTS.

The work in Colorado was carried on in cooperation with C. W. 

Comstock, State engineer, who collected the field data on the stations 

on the Rio Grande and furnished the entire records at a number of 

other stations, as noted in connection with the station descriptions; 

and with the United States Forest Service, which provided the 

services of a hydrographer for measuring the streams in the national 

forests and also furnished the gage heights.

In New Mexico the work was carried on in cooperation with C. D. 

Miller, Territorial engineer, who paid the field expenses incurred for 

most of the New Mexico stations and also paid the gage observers. 

Cooperation with the Atchison, Topeka & Santa Fe Railway Co.
14 STJKFACE WATEK SUPPLY, 1911, PART VIII.

and with other private parties was arranged by the Territorial 

engineer.

The records for Pecos River at Dayton and Lakewood were furnished by the United States Reclamation Service.

Gage heights on the Rio Pueblo de Taos and the Rio Lucero were 

collected by the United States Indian Office.

The stations on the Rio Grande in Texas and Mexico have been 

maintained in cooperation with 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 in the Rio Grande basin were collected by the 

United States Geological Survey under the direction of W. B. Freeman, district engineer, who was assisted by G. A. Gray, E. O. Christiansen, J. B. Stewart, G. H. Russell, O. M. Wimmer, and H. B. Waha. 

Assistance in New Mexico was also rendered by R. L. Cooper and 

C. B. Digby, of the Territorial engineer's office.

With the exception of certain data furnished completely by the 

State of Colorado and the United States Reclamation Service, the 

computations and general review of the data were carried on under 

the direction of R. H. Bolster, hydraulic engineer, by G. K. Larrison, 

H. D. Padgett, A. H. Tuttle, H. J. Dean, and M. I. Walters.

The manuscript was edited by Mrs. B. D. Wood.

BRAZOS RIVER BASIN.

BRAZOS RIVER AT WACO, TEX.

Location. Suspension Bridge on Bridge Street, Waco, Tex.

Records available. September 14, 1898, to December 31, 1911.

Drainage area. 30,800 square miles.

Gage. Chain; attached to downstream upper chord of stiffening truss of bridge. 

So far as known datum unchanged since establishment of station.

Channel. Bed is composed of sand, is free from vegetation, and shifts. Right bank 

of limestone; not inundated by floods; left bank is high but is overflowed at flood 

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

about 300 feet above the bridge. 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.

Discharge measurements. Made from suspension bridge.

Accuracy. The low-stage rating curve is unstable on account of the shifting Bands.

The following measurement was made by R. G. Tyler:

December 27, 1911: Gage height, 5.2 feet; discharge, 2,780 second-feet. This 

measurement does not agree with the 1907-1910 rating curve by a considerable 

difference, and hence estimates of discharge for 1911, which are based on this curve, 

are probably very poor.

COLORADO RIVER (OF TEXAS) BASIN. 

COLORADO RIVER AT AUSTIN, TEX.

Location. At the Congress Avenue Bridge, south of the city of Austin, to which 

point it was removed on the failure of the Austin dam in April, 1900.

Records available. December 21, 1897, to December 31, 1911.

Drainage area. 37,000 square miles.

Gage. A staff consisting of upright posts driven into the bed of the river near the 

bathhouse about 150 feet above the bridge. At stages not readable on the staff 

gage observations are made at the first pier (from the north) on the bridge which 

has been marked up to 21 feet; at stages above 21 feet the chain gage is used.

Channel. Bed of stream composed of sand and gravel; shifts slightly; current 

moderately rapid; neither bank has been overflowed since the dam was washed 

away. The low-water level at this point has been gradually falling for several 

years as a result of 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 channels below, the main one being 

that in which the erosion has taken place; the lowest level recorded was 0.45 

foot by gage August 13-20, 1910.

Discharge measurements. Made from the bridge. No measurements were made 

during 1911, and hence estimates of discharge are withheld.

Daily gage height, in feet, of Colorado River at Austin, Tex.,for 1911.

EVAPOBATION AT AUSTIN, TEX.

The rate of evaporation at Austin has been measured during 1911 at a station at 

the residence of H. B. Beck, adjoining Hyde Park. A cement pit 5 feet square and 

5 feet deep is kept practically full of water in which floats a galvanized pan, 30 inches 

long by 24^ inches wide, so that 1 gill of water will raise the level of the water 0.01 

inch over the surface of the pan. The pan is protected from waves and other disturbing influences by a border of floating planks. The results of the measurements 

are shown in the following table:

The total evaporation for the year amounted to 50.92 inches; rain fell on 58 days 

of the year. .

67443° WSP 308 13 2
18 SURFACE WATER SUPPLY, 1911, PART VIII.

COLORADO RIVER AT COLUMBUS, TEX.

Location. Highway bridge east of Columbus, Tex.

Records available. January 1, 1903, to December 31, 1911.

Drainage area. 40,000 square miles.

Gage. Marked on the downstream side of pier on the west side of the river. No 

change of datum so far as known.

Channel. Bed is composed of gravel and sand and is fairly permanent. At low 

stages the channel is unobstructed by piers, but at high stages the flow is 

obstructed by two piers. At extreme high stages the left bank is overflowed 

for several hundred feet under the trestle approach to the bridge.

Discharge measurements. Made from the bridge.

The following discharge measurement was made by R. G. Tyler: 

December, 1911: Gage height, 10 feet; discharge, 3,890 second-feet. This measurement plots about 30 per cent in excess of the 1907-1910 rating curve, and hence estimates of discharge for 1911 which.are based on this curve are probably very poor.

Daily gage height, in feet, of Colorado River at Columbus, Tex., for 1911.

20 SURFACE WATER SUPPLY, 1911, PART VIII.

BIO GRANDE BASIN.

SEEPAGE INVESTIGATIONS ON THE BIO GRANDE.

An attempt to determine the gains and losses due to seepage on the Rio Grande, by 

measuring the river and all tributaries at various points between the State bridge near 

Lobatos, Colo., and San Marcial, N. Mex., was made by G. H. Russell, junior engineer. 

A series of measurements at different times had been planned, but as yet these 

additional measurements have not been made.

The work was begun at the State bridge near Lobatos, Colo., on March 7, and measurements were successively made down the river as far as San Marcial, N. Mex., the 

last measurement being made March 23.

The gage-height record shows a practically uniform stage of the river at Lobatos 

during this period, but a rise at Buckman, N. Mex., of 0.7 feet on March 11. This rise 

is thought to have been caused mostly by Chama River, which enters the Rio Grande 

a short distance above, but a part was undoubtedly due to melting of snow and a rain 

which occurred in the region around Taos about March 7. This rise, however, preceded th« measurements all the way down, and as the Buckman gage record shows the 

stage of the river to have been practically constant for the several days succeeding the 

rise during which measurements were made, it is thought that the condition of the 

river was fairly even throughout the period.

From the State line down to a point a few miles below Embudo the river flows 

through a box canyon which is cut in a lava formation and ranges in depth from 50 

feet at the State line to about 1,000 feet at Embudo. In this stretch the river is accessible at only a few places, as little water is contributed over the surface except by Red 

River, Rio Pueblo de Taos, and Embudo Creek. The water flowing at the heads of 

several other streams sinks soon after it reaches the sheet of lava that borders the 

river on either side and enters the river as seepage.

Between Embudo and Buckman the canyon widens out into a narrow valley in 

which some irrigation is carried on, and the river spreads out over a sandy bed and 

among islands.

From Buckman the river flows in a comparatively narrow channel through White 

Rocks Canyon to Cochiti. At Cochiti the valley opens again into a flat sandy plain, 

and thence practically to San Marcial the river spreads out over a broad bed and 

among sand bars. Along this stretch considerable irrigation is practiced.

The following tables show the results of the discharge measurements of the tributaries and of the Rio Grande at Lobatos, Dunn's ranch, Velarde, San Juan, Buckman, 

Cochiti, Bernalillo, Albuquerque, Belen, and San Marcial, including the record of 

daily gage heights taken from automatic gages at Lobatos and Buckman, for the 

period covered by the investigation.

At the Lobatos, the mouth of the Rio Hondo, San Juan, Buckman, Cochiti, and San 

Marcial, very good measurements of the Rio Grande were obtained. Conditions at 

the other measured sections were unfavorable and results are only fair.

It should be noted that the river loses little, if any, water by diversion or otherwise 

above Embudo, and that below Embudo more or less water is being diverted for 

irrigation; also, that in the lower stretch considerable loss from evaporation results 

from the spreading of the river over so much area and the openness of the valley.

The tables show an increase in seepage from Lobatos to San Juan, a decrease through 

the open valley from San Juan to Buckman, and an increase through White Rocks 

Canyon from Buckman to Cochiti and as far as Albuquerque. Below Albuquerque 

the increase from seepage lessens, and the lessening continues as far as San Marcial. 

The decrease in flow below Albuquerque is probably to a large extent due to evaporation, for at the time of the measurements very little water was being diverted for 

irrigation. Below Albuquerque the river probably receives little if any seepage 

water.

22 SURFACE WATER SUPPLY, 1911, PART VIII.

BIO GRANDE AT THIRTYMILE BRIDGE, NEAR CREEDE, COLO.

Location. In the Eio Grande National Forest, about 30 miles west of Creede, in 

sec. 13, T. 40 N., E. 4 W., half a mile downstream from the dam site of the Farmers' 

Union Irrigation Co.'s reservoir; 200 feet above mouth of big Squaw Creek.

Records available. June 18, 1909, to October 4, 1911.

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

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

5, 1911.

Channel. Somewhat shifting after high water.

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

when they are made by wading.

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

discontinued.

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

the records represent the natural run-off.

Accuracy. Although the channel shifts somewhat at this station, sufficient measurements have been made to afford a basis for reliable estimates.

Cooperation. Field data furnished through the courtesy of Mr. O. P. Pennock, 

of Creede.

BIO GRANDE NEAR CREEDE, COLO.

Location. In the Rio Grande National Forest, at highway bridge in sec. 6, T. 41 N., 

R. 1 E., one-fourth mile from Wason siding and 3 miles east of Creede. Nearest 

tributary, Willow or Goblin Creek, enters a short distance upstream.

Records available. April 24, 1907, to December 31, 1911.

Drainage area. 705 square miles.

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

referred to the same datum as the chain gage used previously.
SURFACE WATER SUPPLY, 1911, PART vm.

Channel. Practically permanent.

Discharge measurements. Made from bridge.

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

Diversions. Except for a little meadow irrigation no water is diverted above the

station. A number of irrigation reservoirs are being constructed above the

station; one a short distance above will have a capacity nearly equal to the normal

annual flow of the river. 

Accuracy. Good. 

Cooperation. During 1911 this station was maintained in cooperation with the

United States Forest Service and the State engineer.

30 SUKFACE WATEK SUPPLY, 1911, PAET VIII.

BIO GRANDE NEAR BTJCKMAN, N. MEX.1

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

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

R. 8E. 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, 1911.

Drainage area. Not measured.

Gage. Automatic recording gage 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 gage is the same as 

that of the original gage.

Channel. Shifting during high water, but fairly permanent at other times.

Discharge measurements. Made from car and cable 3 miles below the gage. No 

diversions or important tributaries between 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 conditions were favorable for accurate 

results, but the flood caused considerable change, which was not fully covered 

by field work. Thus the estimates for October to December can not be considered better than fair.

Cooperation. During 1911 station was maintained in cooperation with the Territorial engineer.

NOTE. Friez automatic gage removed Apr. 16 and replaced by a Barrett & Lawrence automatic gage 

May 4. Gage readings Apr. 22 and 29 refer to the staff gage attached to the float box. From Aug. 17 to 

Sept. 2 and Sept. 23 to Oct. 29, the automatic gage did not record satisfactorily. Gage heights Aug. 17 to 

Sept. 2 and Sept. 23 to Oct. 15 have been estimated from a hydrograph of the Bio Grande at Lobatos, with 

an additional allowance for tributary streams between Lobatos and Buckman. The crest gage height on 

Oct. 8 was 13.1 feet, as obtained from the automatic sheet.

RIO GRANDE NEAR SAN MARCIAL, N. HEX.

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

San Marcial, N. Mex. No important tributaries enter in the immediate vicinity 

of the station.

Records available. January 29,1895, to December 31,1911.

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

1896, and a wire gage 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 operated since 1901 by the United States section of the 

International Boundary Commission.

BIO GRANDE 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, 1911.

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 Conchos, at

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

Records available. April 8, 1900, to December 31, 1911. 

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 line 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
40 SUKFACE WATEtl SUPPLY, 1911, PAET VHL

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 feet 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.

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

International Boundary Commission.

Discharge measurements of Rio Grande below Presidio, Tex., in 1911.

WESTERN GULF OF MEXICO. 47

BIO GRANDE AT EAGLE PASS, TEX.

Location. Half a mile above the highway bridge at Eagle Pass and about 540 miles 

below El Paso, Tex.

Records available. April, 1900, to December 31, 1911.

Gage. A vertical rod bolted to a shale cliff read to stage 10.5 feet; an inclined rod 

spiked to posts set in the shale is used for stages above 10.5 feet.

Channel. The bed is sandy and shifting. At low water the depth is considerable 

and the current is slow. Right bank is an alluvial deposit and is inundated by 

floods for a distance of about 1,500 feet back from the stream; left bank is of shale 

and rises abruptly from the river to a height above flood stages.

Discharge measurements. Made from cable.

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

International Boundary Commission.

BIO GRANDE NEAR LAREDO, TEX.

Location. Two miles above Laredo and about 670 miles below El Paso.

Records available. May, 1900, to December 31, 1911, except March 1 to July 31,

1903. Earlier records fragmentary. 

Gage. An inclined-rod fastened to posts and trees. Gage was originally located at

highway bridge at Laredo, Tex.; maintained April, 1900, to February 28, 1903.

Measurements were made at this point only from April to September 24, 1900.

Records at this location were poor, hence station was moved 2 miles upstream,

where it has been maintained since August 1, 1903. 

Channel. Bed is sandy and shifting; right bank is of alluvial deposit; left bank is

a shale bluff; both banks are above flood level. 

Discharge measurements. Made from cable. 

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

International Boundary Commission.

RIO GRANDE NEAR BROWNSVILLE, TEX.

Location. About a mile above Brownsville, Tex., and opposite Matamoros, Tamaulipas, Mexico; about 900 miles below El Paso.

Records available. April 29, 1900, to December 31, 1911, 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 fs 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.

Discharge measurements of Rio Grande near Brownsville, Tex., in 1911.

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 December 31, 1911. Also a number of 

discharge measurements made in 1909 by the United States Geological Survey,
54 SURFACE WATER SUPPLY, 1911, PART VIII.

Drainage area. 216 square miles (State engineer's report).

Gage. Inclined staff. The original gage was washed out by flood October 5, 1911,

and was replaced October 16 by a new gage at a different datum. 

Channel. Shifting during high water but fairly permanent at other times. 

Discharge measurements. Made from bridge. 

Winter flow. Ice causes backwater during the winter months. 

Diversions. Little if any water is diverted above the station, and therefore the

records represent the natural run-off. 

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

maintained.

Discharge measurements of South Fork of Rio Grande at South Fork, Colo., in 1911.

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 30, 1911, to December 31, 1911. 

Drainage area. 96 square miles (measured from Hayden's 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 Rio Alamosa

below the station and 410 second-feet from tributaries entering below. 

Accuracy. Owing to the short length of records the station has not been rated and

estimates of discharge are not available. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

CONE JO S RIVER NEAR MOGOTE, COLO.

Location. At Jacob's ranch, in sec. 15, T. 33 N., R. 6 E., 11 miles above Mogote. 

Nearest important tributary, Elk Creek, enters 5 miles above the station. From 

September 1, 1899, to March 31, 1900, and from April 17, 1903, to October 31, 

1905, a station was maintained 4 miles below the present one. The flow at the 

two points is very nearly comparable, as there are no important intervening 

tributaries.

Records available. March 21, 1907, to October 5, 1911.

Drainage area. Not measured,
WESTERN GULF OF MEXICO. 61

Gage. Chain; datum unchanged since its establishment in 1907. The gage was 

washed away by a flood on October 6, 1911, and has not been replaced, as the 

flood so shifted the channel that a new station will have to be selected.

Channel. Fairly permanent.

Discharge measurements. Made from bridge at station.

Winter flow. The river is frozen over during the winter months.

Diversions. There are no court decrees for diversions above, but below the station 

there are decrees for 3,476 second-feet from the Conejos and 1,355 second-feet 

from tributaries entering below.

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

be reliable.

Cooperation. Maintained in cooperation with the State engineer.

NOTE. Observer's gage heights do not agree with hydrographer's gage heights on days of measurements, 

and hence the entire record for 1911 is questionable and should be used with caution. Backwater from 

ice gorge Nov. 12 and 13.

BIO PUEBLO DE TAGS NEAB TAGS, N. MEX.

Location. Two miles above Taos Pueblo and 4J miles northeast of Taos at Glorieta 

Grove, near sec. 2, T. 25 N., R. 13 E. A number of intermittent tributaries enter 

above and below the station.

Becords available. December 19, 1910, to December 12, 1911. Records prior to 

December, 1910, fragmentary and not published.

Drainage area. Not measured.

Gage. An automatic recording gage installed by the United States Indian Service 

December 19, 1910. A vertical staff gage was installed first but was destroyed 

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

referred to 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.

Accuracy. The few discharge measurements indicate that there was not much 

shift during 1911, and therefore the estimates may be considered fairly good.

Cooperation. Station maintained in cooperation with the Territorial engineer, 

United States Indian Office, and United States Forest Service.

WESTERN GULF OF MEXICO. 71

BIO LTTCERO NEAR TAGS, N. MEX.

Location. Just above the headgate of the Seco ditch at the mouth of the canyon 9 

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

the station.

Records available. December 17, 1910, to December 12, 1911, and fragmentary 

records from May to August, 1910.

Drainage area. Not measured.

Gage. An automatic recording gage, 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 slight backwater at gage during the winter months.

Diversions. No diversions above the station. Records represent the natural runoff. 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. Station maintained in cooperation with the Territorial engineer and 

the United States Forest Service.

SANTA PE CHEEK AT MONUMENT BOCK, NEAR SANTA PE, N. MEX.

Location. At Monument Rock, a large conspicuous bowlder 7 miles above Santa 

Fe, in sec. 30, T. 17 N., R. 11 E. No tributaries within several miles of the 

station. From June 1, 1907, to July 16, 1910, and March 8 to November 12, 

1911, a station was maintained at Santa Fe. Between the two stations there 

are no important tributaries, but the Santa Fe Water & Light Co. diverts water.

Becords available. August 29, 1910, to February 25, 1911.

Drainage area. Not measured.

Gage. Vertical staff.

Channel. Somewhat shifting.

Discharge measurements. Made from footbridge.

Winter flow. Ice causes backwater during the winter months.

Diversions. Little or no water is diverted above the station, and therefore the 

records represent closely the natural run-off.

Accuracy. Owing to the meager data, no estimates of discharge are made for 1911.

Cooperation. Station maintained in cooperation with the Territorial engineer.

A record of gage heights from February 5 to 25, 1911, showed an average stage of 

0.8 foot.

August 22, 1908. Since that time it has remained permanent. 

Channel. Shifting.

Discharge measurements. Made from bridge and by wading. 

Winter flow. Ice causes backwater during the winter months. 

Diversions. Water is diverted for the Santa Fe waterworks above the station

and one small irrigation ditch diverts just above. 

Accuracy. Owing to the lack of gage heights, no estimates of daily discharge have

been made.

NOTE. Gage heights affected by presence of ice Jan. 1 to 14 and Dec. 12 to 31; gage heights after May 

14 read from a gage three-fourths mUe downstream from the original gage. This gage is referred to a new 

datum.

PECOS EIVEE AT SANTA ROSA, N. MEX.

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

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

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

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

to a different datum.

Records available. February 1, 1910, to July 31, 1911.

Drainage area. 2,780 square miles (measured from 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.

Cooperation. Maintained in cooperation with the Territorial engineer.

PECOS RIVER NEAR DAYTON, N. MEX.

Location. Three miles east of Dayton, in sec. 13, T. 18 S., R. 26 E.; 100 feet 

below the mouth of Penasco River.

Becords available . March 24, 1905, to December 31, 1911.

Drainage area. Not measured. '

Gage. Vertical staff. The original gage 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. Station maintained in cooperation with the United States Reclamation Service, by which the field data are furnished.

GALLINAS RIVER NEA/l LAS VEGAS, N. HEX.

Location. At Las Vegas Hot Springe, 6 miles northwest of Las Vegas near sec. 1, 

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

Records available. August 13, 1903, to December 31, 1911.

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

Gage. Vertical staff 600 feet above the power house footbridge, 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.
WESTERN GULP OF MEXICO. 89

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 Aqua Pura Co., which furnishes 

Las Vegas and the Atchison, Topeka & 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.

Cooperation. Maintained in cooperation with the Territorial engineer.

BIO SAN JTJAN BASIN. 

BIO SAN JUAN NEAR SANTA ROSALIA RANCH, TAMAULIPAS, MEXICO.

Location. Near the Santa Rosalia ranch, 12 miles aboye 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, 1911 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 restored gage has not the same 

datum as the old. No flow is now 8.5 feet on the gage.

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

INTERIOR BASINS IN NEW MEXICO.

GENERAL FEATURES. 1

The southern portions of Arizona and New Mexico and the western part of Texas 

resemble the Great Basin in climate, and they contain a number of small interior 

basins [basins completely encircled by lines of water parting]. These are not so 

fully determined in extent as the Great Basin, but several of them may be approximately indicated. One of the largest lies between the Rio Grande and its eastern 

branch, the Pecos, extending from latitude 35° in central New Mexico to latitude 31° 

in western Texas. In its broadest part it is bounded on the west by the San Andreas 

and Organ Mountains, and on the east by the Sacramento and Guadalupe. Its area, 

of which two-thirds lies in New Mexico, is about 12,500 square miles. [In this area 

are Rio Tularosa and Rio La Luz.] Southwest of the Rio Grande, in Mexico, there 

is a larger tract of interior drainage, containing a number of saline lakes, and to one 

of these, Lake Guzman, the valley of the Mimbres River of New. Mexico descends. 

Other basins adjacent on either side to that of the Mimbres are believed to bear the 

same relation to Lake Guzman, sloping gently toward it but contributing no water 

unless during periods of rare and exceptional storm. Yet other basins without exterior 

drainage are contiguous to these, and unite to form in southwestern New Mexico an 

arm of the Mexican district of interior drainage, the area within New Mexico probably 

falling between 7,000 and 7,500 square miles.

RIO TULAROSA BASIN.

EIO TULAKOSA NEAR BENT, N. MEX.

Location. In sec. 28, T. 13 S., R. 12 E., 2 miles east of Bent. No important tributaries within several miles of the station. 

Records available. May 24, 1911, to December 31, 1911. 

Drainage area. Not measured. 

Gage. Vertical staff. 

Channel. Data too meager to determine. 

Discharge measurements. Made by wading.

i Extract from Gilbert, G. K., Lake Bonneville: Mon. U. S. Geol. Survey, vol. 1,1890, pp. 2-12, PI. II. 

This report is now out of print but may be consulted in the libraries of most of the larger cities.
WESTERN GULF OF MEXICO. 101

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

Diversions. A number of small ditches divert water for irrigation above the station. 

Accuracy. Owing to a lack of discharge measurements no estimates of flow can be

made. 

Cooperation. Station maintained in cooperation with the Territotial engineer and

the United States Forest Service.

The following discharge measurement was made by H. B. Waha: 

May 24, 1911: Gage height, 1.32 feet; discharge, 9.4 second-feet.

Daily gage height, in feet, of Rio Tularosa, near Bent, N. Mex.,for 1911.

BIO LA LTJZ BASIN. 

RIO LA LUZ NEAR LA LUZ, N. MEX.

Location. In the Alamo National Forest, 1 mile above La Luz, in sec. 30, T. 15 S., 

R. HE.; half a mile below the mouth of Rio Fresnal, the nearest tributary.

Records available. Fragmentary records August 13, 1910, to June 21, 1911.

Drainage area. Not measured.

Gage. Inclined staff. The original gage was washed out and a second gage established November 23, 1910, at a different datum.

Channel. Data too meager to determine.

Discharge measurements. Made by wading.

Winter flow. No data.

Diversions. There are no important diversions above the station, but several below. 

The records at the station represent closely the natural run-off.

Accuracy. Owing to the meagerness of the data no estimates of flow can be made.

Cooperation. Station was maintained in cooperation with the United States Forest 

Service and the Territorial engineer.

MIMBRES RIVER BASIN.

MIMBRES RIVER NEAR FAYWOOD, N. MEX.

Location. About 6 miles northeast of Faywood Hot Springs, and 10 miles from Faywood, a station on the Silver City branch of the Atchison, Topeka & Santa Fe 

Railway in sec. 7, T. 20 S., R. 10 W.

Records available. April 8, 1908, to December 31, 1911.

Drainage area. Approximately 450 square miles.

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

upstream from the Bite 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 3 feet lower 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 below the station, and 400 feet 

above is the dam site of the Rio Mimbres reservoir, which is designed to control 

the flood water for irrigation.

Accuracy. Owing to the shifting character of the stream and the few discharge 

measurements, no estimates of flow can be made.

Cooperation. Station maintained in cooperation with the Territorial engineer.
