SURFACE WATER SUPPLY OF THE COLORADO RIVER BASIN, 1938

SCOPE OF WORK

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

and flow made on streams, lakes, and reservoirs In the United States during the water year 

ending September 30, 1938. The work was begun In 1888 In connection with special studies 

relating to Irrigation. Measurements of stream flow have been made at about 7,800 points 

In the United States and also at many points In Alaska and the Hawaiian Islands. In July 

1938, 3,830 gaging stations were being maintained by the Geological Survey and 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 9.

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 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 of water 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. It Is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 645,317 gallons and 

represents a run-off of 0.0372 Inches from one square mile.

"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

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 EXPLANATION OF DATA

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 daily gage height to these rating tables gives tlie 

daily discharge, from which the monthly and yearly mean discharge are 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 daily 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 daily discharge for the greater part of the year 

was determined by the shifting-control method, the slope method, or other special methods.

The description of the station gives the type of gage, its latitude ard 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 meximum discharge 

and gage height; the minimum discharge if there is little or no regulation; the minimum 

daily 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 peak discharge 

for the year with the time of its occurrence is given below the table of monthly discharge 

for some stations. Selected lower peaks are also given if the peak disciarge exceeded the 

mean discharge for that day by more than 10 percent. This supplementary information is 

generally not given for stations having drainage areas of less than 10 souare miles or 

more than 10,000 square miles.

The table of daily 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 flashy floods the mean daily discharge is determined from gage-height 

graphs based on gage readings made once or twice dally or oftener, as sts.ted in the station description. For stations equipped with water-stage recorders the table gives the 

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

daily gage height may not indicate the true mean daily 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 daily discharge from a continuous gs.ge-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 figures for that month given in the table of daily discharge. The 

column headed "Maximum" gives the maximum daily discharge and not the discharge when the 

water surface was at crest height. Likewise, in the column headed "Minlirum". the quantity 

given Is the minimum daily discharge. The column headed "Mean" is the average flow in

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 in regard to the general accuracy of the 

records. "Excellent" indicates that, in general, the daily records are accurate within 

5 percent; "good", within 10 percent; "fair", within 15 percent; and "poor", within 20 

percent or more.

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 of the river above the station. "Second-feet per square mile" 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 whic1! the annual 

rainfall is less than 20 inches.

Many gaging stations on streams in the irrigated areas of the United Spates are situated above most of the diversions from those streams, so that 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.

Note.- The reports that contain records after 1901 are given In the table on page 6.

The table on the following page gives, by years and drainage basins, the numbers of 

the papers on surface water supply published from 1899 to 1938. 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, 523, 353, 403, 

433, 453, 473, and 503, which contain records for thb 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, the streams and puints of measurement listed appearing in the same 

relative order as the streams and gaging stations in the body of the report. An index of 

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

COOPERATION

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

Arizona (except for Virgin River at Littlefleld), with the office of the State water 

commissioner, Jesse C. Wanslee, the Salt River Valley Water Users' Association (for certain stations In Salt River Basin), the Metropolitan Water District of Southern 

California (for certain stations on Williams River and on Colorado River below Boulder 

Dam), and the Arizona Water Conservation District (for Kassayampa River at Box dam site, 

near Wlckenburg); In Colorado, with the office of the State engineer, M. C. Hlnderllder; 

In New Mexico, with the office of the State engineer, Thomas M. McClure, and the New 

Mexico Interstate Stream Commission, Thomas M. McClure, secretary; in Utah, with the

office of the State engineer, T. H. Humpherys; and in Wyoming, with the office of the 

State engineer, John D. Qulnn.

Assistance In collecting the records was rendered by the following: In Arizona, by 

the Gila River water commissioner, Charles A. Firth, appointed by the United States 

District Court; In Colorado, by the Denver Board oC Water Commissioners, the Bureau of 

Reclamation, and the Uncompahgre Valley Water Users' Association; In Tfow Mexico, by the 

Indian Service; in Utah, by the National Park Service, the Bureau of Reclamation, the 

Indian Service, and the Utah Power & Light Co.; and In Wyoming, by the United States 

Weather Bureau.

Funds for the construction, repair, and improvement of gaging stations were allocated 

to the Geological Survey by the Federal Emergency Administration of Public Works.

DIVISION OF WORK

Data for stations in the several States were collected and prepared for publication 

under the supervision of the district engineers, as follows: In Arizona (except for 

Virgin River at Littlefleld) and for all stations on Colorado River below the ArizonaUtah State line, W. E. Dlcklnson, succeeded In April 1938 by J. H. Gardlner; In Colorado

Grand Junction vrater supply and 17 miles east of Whitewater.

Drainage area.- 55.0 square miles.

Records available.- October 1317 to September 1921 and October 1933 to September 1938 in 

reports of Geological Survey. October 1917 to September 1921 and August 1922 to 

September 1938 in reports of State engineer.

Average discharge (including flow diverted by pipe line above station).- 20 years, 41.4 

second-feet.

Extremes (combined flow).- Maximum discharge during year, 992 second-feet May 28; minimum daily discharge, 5.7 second-feet Apr. 1.

1917-21, 1922-38: Maximum discharge, 1,630 second-feet June 6, 1921 (gage height, 

4.5 feet, former site and datum); minimum daily discharge that of Apr. 1, 1938.

Remarks.- Records excellent except those for period of ice effect, Dec. 19 to Feb. 1, 

FeBT~5-14, 18-26, which were computed on basis of two discharge measurements and 

weather records and are good. Figures of diverted flow for Grand Junction water 

supply (obtained from several readings made each day on Cippoletti weir) are furnished 

by State engineer and added to monthly discharge to give total flew of stream. Records 

of combined flow excellent. Regulation by a few small reservoirs above station.
