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 fie water year 

ending September 30, 1940. The work was begun In 1888 In connection with special studies 

relating to Irrigation. Measurements of the flow of streams and of the stage and contents 

of lakes and reservoirs have been made at about 8,800 gaging stations In the United States 

and also ato many gaging stations In Alaska and Hawaii. In July 1940, 4,760 gaging stations 

were being maintained by the Geological Survey and cooperating organizations. Miscellaneous discharge measurements were made at many 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. Cooperation of the first 

kind Is acknowledged 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 a stream whose channel is 1 square foot In cross-sectional area and 

whose 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 

draining 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" Is the quantity of water required to cover an acre to the depth of 1 

foot and Is equivalent to 43,560 cubic feet. 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 646,317 gallons and 

represents a run-off of 0.0372 Inch 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 a feature below the gage that defines the stagedischarge relation at the gage. This feature may be a natural section, a reach of the 

channel, or an artificial structure.

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 records of stage anc1 discharge

2 EXPLANATION OF DATA

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

direct readings on a nonrecordlng 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 structures in use at gaging stations are shown on plate 1.

Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application of the mean' dally gage height to these rating tables gives the 

mean dally discharge, from which the monthly and yearly mean discharge are computed.

For most of the gaging stations In the area covered by this report the data presented 

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 dally discharge for the greater part of the year 

was determined by the shifting-control method, the slope method, or other spaclal 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 ar<3 10 or more 

complete years of record. Under "Extremes" are given the maximum discharge and gage 

height; the minimum discharge if there Is little or no regulation; the minim-mi dally 

discharge if there is extensive regulation (also the minimum discharge If useful); and the 

minimum gage height (unless 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 discharge represents the lowest stage, 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 discharge 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 square 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 readings of the gage or the mean of 

twice-daily readings. For flashy floods the mean daily discharge is determined from gageheight graphs based on gage readings made once or twice daily or oftener, as stated In the 

station description. For stations equipped with water-stage recorders, except those on 

streams subject to sudden or rapid fluctuation, the table gives the dischargs corresponding to the mean daily gage height. For stations subject to such fluctuation 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 dally discharge from a continuous gage-height graph 

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

At some gaging stations the stage-discharge relation is affected by backwater from 

reservoirs, tributary streams, or other sources, which necessitates the use of the slope 

or fall In a reach of the stream as a factor in the determination of discharge. Information requisite for determining the slope or fall is obtained by means of an auxiliary

gage set at some distance from the base gage. The auxiliary gage, If one Is used, Is 

described under "Location." At some stations the stage-discharge relation Is affected by 

changing stage, and for them the rate of change of stage Is used as a factor In the determination of discharge.

At most gaging stations In the northern part of the United States and at some In the 

mountainous regions of other parts the stage-discharge relation is affected by ice during 

the winter, which makes It Impossible to compute the discharge in the usual manner. Discharge for periods of ice effect is computed on the basis of occasional winter discharge 

measurements and gage heights, consideration being given to the available information on 

temperature and precipitation, notes by gage observers and engineers, and comparable 

records of discharge for stations In the same or nearby basins. The days included in the 

periods of ice effect and the days during the winter period on which discharge measurements were made are indicated In the table by symbols referring to footnotes.

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 dally discharge. The 

column headed "Maximum" gives the maximum daily discharge and not the instantaneous discharge when the water surface was at crest stage. Likewise, In the column headed "Minimum" 

the quantity given is the minimum daily discharge. The column headed "Mean" gives the 

average flow in cubic feet per second during the month.

ACCURACY OF FIELD DATA AMD COMPUTED RESUITS

The accuracy of stream-flow data depends primarily on (1) the permanenc7 of the stagedischarge relation and (2) 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 or 

a higher percent.

Yield at some stations as indicated by monthly means may vary widely from natural yield, 

owing to diversion, consumption, regulation by storage, Increase or decrease 'in evaporation 

due to artificial causes, or other factors. For such stations figures of "second-feet per 

square mile" and "run-off in inches" are not published unless storage or d'.version records 

are Included indicating the extent of the regulation or diversion or unless satisfactory 

adjustments can be made for changes in contents of reservoirs or for other changes incident to use and control. Figures of second-feet per square mile and run-off in Inches 

are also omitted if the drainage area includes large noncontributing areas or if the 

average annual rainfall over the drainage area is less than 20 inches.

Many gaging stations on streams in the irrigated areas of fche United States are situated above most of the diversions from those streams, and therefore 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 rny be expected

to throw new light on data previously published, and that greater degrees of refinement 

In computations and records may be warranted with the Increase In data and the use of 

Improved equipment.

Note.- Reports containing records for years after 1901 are given in 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 1940. 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 for 1910 to 1920 for any station in the 

area covered by par"t 3 are published in Water-Supply Papers 283, 303, 323, 353, 403, 433, 

453, 473, 503, which contain records for the Ohio River Basin for those veers.

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 points 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.

RECORDS OF DISCHARGE COLLECTED BY AGENCIES OTHER THAN THE GEOLOGICAL SURVEY

During the period October 1939 to September 1940 the Soil Conservation Service, United 

States Department of Agriculture, has collected records of discharge from areas as 

follows:

In the vicinity of Hastings, Nebr., from 6,045 acres consisting of 21 areas; 1 of 

3,470 acres, 1 of 2,040 acres, 1 of 481 acres, and 18 of about 3 acres eech. These 

records are in the files of the Soil Conservation Service and are not contained in the 

publications of the Geological Survey.

In the vicinity of Clarinda, Iowa, from 5 areas of less than 5 acres each.

In the vicinity of Bethany, Mo., from 8 areas of less than 10 acres erch.

COOPERATION

The work in the several States was done under cooperative agreements v-lth the organizations listed below:

Colorado: Office of the State engineer, M. C. HInderlider. 

Iowa: Iowa Geological Survey, Dr. A. C. Trowbridge, director; Uriversity of 

Iowa Institute of Hydraulic Research, Prof. E. W. Lane, associate director, and 

Francis M. Dawson, dean of College of Engineering; and the State Conservation 

Commission, M. L. Hutton, director.

Financial assistance was furnished by the Corps of Engineers, U. S. Army, In the operation of 87 gaging stations, 2 of which were In Colorado, 11 In Iowa, 18 In Kansas, 13 

In Missouri, 12 In Montana, 4 in Nebraska, 7 in North Dakota, 16 in South Dakota, and 4 

in Wyoming.

Financial assistance was also furnished by the Soil Conservation Service of the- United 

States Department of Agriculture; the Weather Bureau of the United States Department of 

Commerce; the Fish and Wildlife Service, and the Office of Indian Affairs of tte United 

States Department of the Interior; and the United States Department of State.

Assistance in collecting records was rendered also by the following municipelities, 

organizations, corporations, and individuals:

Full cooperation exists between the Geological Survey of the United States Department 

of the Interior and the Dominion Water and Power Bureau, Department of Mines and Resources, 

Canada. On waters adjacent to the international boundary certain stations are maintained 

Jointly by the United States and Canada under the terms of the Boundary Waters Treaty of 

1909, and others are maintained under a subsequent agreement between the two Governments. 

The records from all these stations are obtained in such a manner as to be equally acceptable and available in either country. These stations are herein designated "international gaging stations."

DIVISION OF WORK

The stream-gaging work was conducted by the water resources branch of the Geological 

Survey, Glenn L. Parker, chief hydraulic engineer, Carl G. Paulsen, assistant chief 

hydraulic engineer, and Rudolph G. Kasel, chief of the division of surface waters. The 

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

under the supervision of the district engineers as follows: In Colorado, Robert Follansbee, 

the work being done in collaboration with M. C. Hinderlider, State engineer, and L. T. 

Burgess, State chief hydrographer; in Iowa (except for Tarkio River at Blanchard and

Records available.- February 1934 to September 1940.

Extremes.- Maximum discharge during year, 13,800 second-feet June 3 (gage 1-elght, 6.38 

feet); minimum, 1,440 second-feet about Dec. 28 (gage height, 2.07 feet).

1934-40: Maximum discharge, 37,500 second-feet June 25, 1938, from rating curve 

extended above 24,000 second-feet; maximum gage height recorded, 14.49 feet Mar. 16, 

1935, while ice was breaking; minimum discharge, 1,120 second-feet July 8, 1936 (gage 

height, 1.92 feet).

Remarks.- Records good except those for periods when observer's readings were used, which 

are fair and those for period of ice effect, which are poor. Many diversions from 

tributaries. Flow partly regulated by reservoirs. Considerable fluctuation at medium 

and low stages caused by power plants above station.

LITTLE SIOUX RIVER BASIN 

Spirit Lake at Orleans, Iowa

227

Location.- Float gage in pipe well, lat. 43°27', long. 95°06', in sec. 27, T. 100 N., R. 

36 W., at State fish hatchery at Orleans. Datum of gage is 90.00 feet above Iowa Lake 

Survey datum and 1,387.25 feet above mean sea level (general adjustment of 1929).

Records available.- May 1933 to September 1940.

Extremes.- Maximum gage height observed during year, 10.78 feet June 7; minimum observed, 

 9.42 feet Sept. 21, 23. ,

1933-39: Maximum gage height observed, 11.80 feet May 26, 1939; minimum observed, 

6.75 feet Oct. 20, 1935.

Remarks.- Gage heights influenced by changes in direction and velocity of wind. No discharge from lake during year. During period Apr. 18 to May 14, water was being pumped 

from lake through main to which gage well is attached, this caused drawdown in well as 

indicated by levels run to lake surface on May 3. A correction of 0.14 foot was added 

to gage heights during this period.
