SURFACE WATER SUPPLY OF THE COLORADO RIVER BASIN, 1955

SCOPE OF WORK

This volume Is one or a series of 14 reports presenting results of measurements of flow 

made on streams in the United States during the year ending September 30, 1935. The work 

was begun in 1888 in connection with special studies relating to irrigation. In the execution of the work, measurements of stream flow have been made at about 7,020 points in the 

United States and also at many points in Alaska and the Hawaiian Islands. In July 1935, 

3,020 gaging stations were being maintained by the Geological Survey and the cooperating 

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

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 v/hen 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 the 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

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 oi stage are obtained either 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.

8 ACCURACY OF FIELD DATA AND COMPUTED RESULTS

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 front the discharge 

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

daily 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 information in regard to the location and type of 

gage, 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 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 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 daily 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 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 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'1 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 daily 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 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 wlilch 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 dally 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.

In order to permit greater refinement in analysis and comparison of records for adjacent stations, the following changes in computation procedure were followed in preparing 

some of the records published in the series of reports for 1934 and all the records for 

1935: (a) Mean monthly discharge above 1,000 second-feet and monthly run-off above 10,000 

acre-feet are expressed to four significant figures instead of three significant figures, 

as formerly; (b) monthly run-off in acre-feet is computed from the total second-foot-days 

for the month and not from the mean discharge for the month; (c) drainage areas above 

1,000 square miles, if measured on topographic maps, or if otherwise warranted, are expressed to four significant figures Instead of three as formerly.

PUBLICATIONS

The results of stream-flow measurements are now published annually in 14 parts (parts 

12, 13, and 14 were formerly 12-A, 12-B, and 12-C), each part covering an area whose

Hote.- The reports which contain records after 1901 are given In the table on page 12.

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 reports containing records obtained prior to 1904 has been published in Water-Supply 

Paper 119.

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

surface-water supply published from 1899 to 1935. 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, 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. Special papers 

containing oonpllatlon of records previously published and also records not contained in 

the annual series of water-supply papers have been published for some States and drainage 

basins. For example, stream-flow records for the New-Kanawha River Basin In part 3 from 

1895 to 1920 are contained in Water-Supply Paper 536.
