SURFACE WATER SUPPLY OF THE COLORADO RIVER BASIN, 1937

SCOPE OF WORK

This volume is one of a series of 14 reports presenting results of measurements of 

flow made on streams In the United States during the water year ending September 30, 1937. 

The work was begun In 1888 In connection with special studies- relating to Irrigation. 

Measurements of stream flow have been made at about 7,200 points In the United States 

and also at many points In Alaska and the Hawaiian Islands. In July 1937, 3,380 

gaging stations were being maintained by the Geological Survey and the cooperating 

organizations. Many miscellaneous discharge measurements were made at other points.

In the execution of the work many state and private organizations have cooperated, 

either by furnishing data or by assisting in collecting data. Acknowledgments for 

cooperation of the first kind are made in connection with the description of each station affected; cooperation of the second kind is acknowledged on page 8.

DEFINITION OF TERMS

The units in which stream-flow data are presented In this report and other terms used 

herein are defined as follows:

"Second-feet" Is an abbreviation for "cubic feet per second." A second-foot Is a 

rate of flow of 1 cubic foot per second, or the rate of discharge of water flowing in a 

channel when the cross-sectional area Is 1 square foot and the average velocity Is 1 

foot per second.

"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 an area would be covered If all the water 

flowing from It in a given period were uniformly distributed on Its surface. It Is used 

for comparing run-off with rainfall, which Is usually expressed in Inches.

An "acre-foot", equivalent to 43,560 cubic feet, 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.

"Second-foot-day" Is the volume of water represented by a flow of 1 second-foot for 

24 hours.

"Stage-discharge relation" Is an abbreviation for the term "relation of gage height to 

discharge."

"Control" is a term used to designate the natural section or reach of the channel or 

artificial structure below the gage which determines the stage-discharge relation at the 

gage.

EXPLANATION OF DATA

The base data collected at gaging stations consist of records of stage, measurements 

of discharge, and general Information used to supplement the gage heights and discharge 

measurements in determining the dally flow. The records of stage are obtained either

1
2 ACCURACY OF FIELD DATA AMD COMPUTED RESULTS

from direct readings on a nonrecording gage or from a water-stage recorder that gives a 

continuous record of the fluctuations. Measurements of discharge are made with a current 

meter by the general methods outlined In standard textbooks on the measurement of river 

discharge. Typical gaging stations, equipped with water-stage recorder and measuring 

cable and car, are shown on plate 1.

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

measurements. The application of the dally gage height to these rating tables gives the 

dally discharge from which the monthly and yearly mean discharge Is computed.

The data presented for each gaging station In the area covered by this report usually 

comprise a description of the station, a table showing the dally discharge of the stream, 

and a table of monthly and yearly discharge and run-off. Skeleton rating tables are published except for those stations whose dally discharge for the greater part of the year 

was determined by shifting-control method or by use of slope or other special methods.

The description of the station gives the type of gage, Its latitude and longitude 

determined from the best available maps, and Information In regard to diversions that 

decrease the flow at the gage, artificial regulation from pondage or storage, and the 

accuracy of the records. Under "Average discharge" Is given the average discharge for 

the number of years Indicated. It Is given only for stations for which there are 10 or 

more complete years of record. Information under "Extremes" gives the maximum discharge 

and gage height; the minimum discharge If there Is little or no regulation; the minimum 

dally discharge if there Is extensive regulation, and also the minimum discharge If useful; and the minimum gage height except when It Is of no Importance. Unless otherwise 

qualified, the maximum discharge corresponds to the crest stage obtained by use of a 

water-stage recorder or a nonrecording gage read at the time of the crest. Likewise the 

minimum represents the lowest discharge unless otherwise qualified.

The table of dally discharge gives, for stations equipped with nonrecording gages, 

the discharge in second-feet corresponding to once-daily or the mean of twice-daily readings of the gage. For stations equipped with water-stage recorders the table gives the 

discharge corresponding to the mean dally gage height except for stations on streams subject to sudden or rapid fluctuation. For stations subject to such fluctuation the mean 

dally gage height may not indicate the true mean dally discharge, which must be obtained 

by averaging the discharge for Intervals of the day or by using the discharge Integrator, 

an Instrument for obtaining the mean dally discharge from a continuous gage-height graph 

and containing as an essential element the rating curve of the station.

In the table of monthly discharge the column headed "Second-foot-days" gives the sum 

for each month of the discharge given In the table Of dally discharge. The column headed 

"Maximum" gives the maximum dally discharge and not the discharge when the water surface 

was at crest height. Likewise, In the column headed "Minimum" the quantity given Is the 

minimum dally discharge. The column headed "Mean" Is the average flow In cubic feet per 

second during the month.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily (1) on the permanency of the stagedischarge relation and (2) on the accuracy of observation of stage, measurements of flow, 

and Interpretation of records.

The station description gives a statement under Remarks In regard to the general 

accuracy of the records. "Excellent" Indicates that, In general, the dally records are

in error not more than 5 percent; "good", not more than 10 percent; "fair", not more 

than 15 percent; and. "poor", over 15 percent.

The monthly means for any station may represent with high accuracy the quantity of 

water flowing past the gage, but the figures showing discharge per square mile and depth 

in inches may be subject to gross errors caused by the inclusion of large noncontributing 

districts In the measured drainage area, by lack of information concerning water diverted 

for irrigation or other use, or by inability to interpret the effect of artificial regulation of the flow o£ the river above the station. "Second-feet per square mile 1' and 

"run-off in inches" are therefore not computed if such errors appear probable. The computations are also omitted for stations on streams draining areas in which the annual 

rainfall is less than 20 inches.

Many gaging stations on streams in the Irrigated areas of the United States are situated above most of the diversions from those streams, and the discharge recorded does not 

show the water supply available for further development, as prior appropriations below 

the station must first be satisfied.

The table of monthly discharge gives a general idea of the flow at the station. The 

table of daily discharge allows more detailed studies of the variation In flow. It 

should be borne in mind, however, that the observations In each succeeding year may be 

expected to throw new light on data previously published, and that greater degrees of refinement in computations and records may be warranted with increased data and use of improved equipment.

The foregoing table gives, by years and drainage basins, the numbers of the papers on 

surface water supply published from 1899 to 1937. The data for any particular station 

will, in general, be found in the reports covering the years during which the station was 

maintained. For example, the data from 1910 to 1920 for any station in the area covered 

by part 3 are published in Water-supply Papers 283, 303, 323, 353, 383, 403, 433, 453, 

473, and 503, which contain records for the Ohio River Basin for those years.

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

years. Miscellaneous measurements at many points other than regular gaging stations have 

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

end of each report in the same relative order as the regular gaging stations. An index 

of the records obtained prior to 1904 has been published in Water-supply Paper 119.

From time to time reports have been published that are compilations of records for 

various areas, usually a single State or drainage basin. These reports contain records 

previously published (some of which have been revised), as well as some records not contained in the annual series of water-supply papers. The following table gives the 

numbers and titles of these reports, arranged in alphabetical order by States and 

drainage basins.

*Records for some earlier years published In water-supply papers of Geological Survey.

tRecords not published. Gage Is read only once a day and there Is considerable diurnal 

fluctuation owing to operation of the Shoshone power plant near Glenwood Springs.

^Records not published; their accuracy Is doubtful owing to variable control on account of diversion to Gunnlson Tunnel below station.

COOPERATION

The work In the several States was done under cooperative agreements as follows: In 

Arizona, with the office of the State water commissioner, Jesse 0. Wanslee, the Salt 

River Valley Water Users' Association (for certain stations In Salt River Basin), and 

the Metropolitan Water District of Southern California (for stations on Colorado River 

near Topock and near Parker); In Colorado, with the office of the State engineer, 11. C. 

Hlnderllder; In New Mexico, with the office of the State engineer, Thomas w. McClure; In 

Utah, with the office of the State engineer, T. H. Humpherys; In Wyoming, with the office 

of the State engineer, John D. Qulnn.

Assistance In collecting the records was rendered by the following organizations and 

corporations: In Arizona, by the Indian Service and the Gila River water commissioner, 

Charles A. Firth; in Colorado, by the Denver Board of Water Commissioners, the Bureau 

of Reclamation, and Uncompahgre Valley Water Users' Association; in New Mexico, by the 

Indian Service; in Utah, by the National Park Service, the Indian Service, and the Utah

Remarks.- Records excellent above 1,000 second-feet; good below, those of river for

 Jan7 6 to Mar. 2 computed on basis of gage heights, two discharge measurements, and 

weather records. Diversions for Irrigation above station. Combined flow of river 

and Redlands Power Canal minus about 25 second-feet diverted for Irrigation during 

irrigation season represents flow that enters Colorado River. Discharge fablps 

include flow of the power canal.

108 SAN JUAN RIVER BASIN

San Juan River at Shiprock:, N. Uex.

Location.- Water-stage recorder, lat. 36°47', long. 108°44', In about sec. 22, T. 30 N., 

R. IB ¥., 3 miles northwest of Shiprock and about 6 miles below mouth of Chaco River. 

On July 9, 1936, gage datum was lowered 1.54 feet.

Records available.- January to October 1911, October 1930 to September 1931 and October 

I9t5a to September 1937 In reports of Geological Survey; January to October 1911 and 

November 1915 to December 1931 In reports of State engineer.

Extremes.- Maximum discharge during year, 17,900 second-feet Apr. 16 (gage height, 7.98 

 feet),.from rating curve extended above 14,200 second-feet; minimum dally discharge,

84 second-feet Sept. 23.

1930-31, 1932-37: Maximum discharge, about 44,200 second-feet Sept. 28, 1935

(gage height, 9.44 feet, present datum, from high-water marks), from rating curve

extended about 20,000 second-feet; minimum daily discharge 10 second-feet (estimated).

July 2-7, 1934.

Stage of about 6.5 feet, former site and datum, occurred Aug. 11, 1929 (discharge,

about 80,000 second-feet). A greater discharge probably occurred Oct. 6, 1911, when

stage of 22.0 feet on old gage relation (relation to present datum unknown) was

recorded.

Remarks.- Records fair except those for Dec. 12-14, Jan. 4 to Feb. 18, which were computed on basis of weather records, two discharge measurements, and records for stations at Pagosa Springs and Farmington, wlilch are poor. Diversions for irrigation 

above station.

S., R. 19 E., 1,600 feet below Gypsum Wash, 1,800 feet above bridge, and 20 miles 

southwest of Bluff.

Drainage area.- 24,000 square miles.

Records available.- October 1914 to September 1917, March 1927 to September 1937.

Average discharge.- 12 years (1915-17, 1927-37), 2,879 second-feet.

Extremes.- Maximum discharge during year, about 23,000 second-feet Sept. 30 (gage height, 

17.6 feet, from high-water mark); minimum observed, 105 second-feet Aug. 29.

1915-17, 1927-37: Maximum discharge, about 70,000 second-feet Sept. 10, 1927 

(gage height, 32.0 feet); no flow July 3-13, 1934.

Flood of Oct. 6, 1911, which was greatest known at Shlprock, N. Mex., probably 

exceeded that of Sept. 10, 1927, at this station, but stage was not accurately 

determined.

Remarks.- Records good except those for period of ice effect Jan. 5 to Feb. 5 which 

were computed on basis of records for station at Shiprock, N. Mex., and weather 

records and are poor.
