AUTHORIZATION AND SCOPE OF WORK

This volume is one of a series of 14 reports presenting records of 

measurements of flow made on streams in the United States during 

the year ending September 30,1925.

The data presented in these reports were collected by the United 

States Geological Survey under the following authority contained in 

the organic law (20 Stat. L., p. 394):

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 

relating to irrigation. Since the fiscal year ending June 30, 1895, 

successive appropriation bills passed by Congress have carried the 

following items:

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.

In this work many private and State organizations have cooperated, either by furnishing records 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 10.

Measurements of stream flow have been made at about 5,120 

points in the United States and also at many points in Alaska and 

the Hawaiian Islands. In July, 1925, 1,710 gaging stations were

1
2 SURFACE WATEB SUPPLY, 1925, PAET V

being maintained by the Geological Survey »nd the cooperating 

organizations. Many miscellaneous discharge measurements are 

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 water-supply papers from time to time.

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 devided 

into two groups (1) those that represent a rate of flow, as second-feet, 

gallons per minute, miner's inches, and discharge in second-feet per 

square mile, and (2) those that represent the actual quantity of water, 

as run-off in inches, acre-feet, and millions of cubic feet. The principal terms used in this series of reports are second-feet, second-feet 

per square mile, run-off in inches, and acre-feet. They may be 

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 of 

rectangular cross section 1 foot wide and 1 foot deep at an average 

velocity of 1 foot per second. It is generally used as a fundamental 

unit from which others are computed.

"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.

The following terms not in common use are here defined:

" Stage-discharge relation "; an abbreviation for the term " relation 

of gage height to discharge."

"Control"; a term used to designate the section or sections of 

the stream channel below the gage which determine the stagedischarge relation at the gage. It should be noted that the control 

may not be the same section or sections at all stages.

The "point of zero flow " for a gaging station is that point on the 

gage the gage height at which water ceases to flow over the 

control.
SURFACE WATER SUPPLY, 1925, PART V 6

EXPLANATION OF DATA

The data presented in this report cover the year beginning October 1, 1924, and ending September 30, 1925. At the beginning of 

January in most parts of the United States much of the precipitation 

in the proceeding three months is stored in the form of snow or ice, 

or in ponds, lakes, and swamps, as ground water, and this stored 

water passes off in the streams during the spring break-up. At the 

end of September, on the other hand, the only stored water available 

for run-off is possibly a small quantity in the ground; therefore the 

run-off for the year beginning October 1 is practically all derived 

from precipitation within that year.

The base data collected at gaging stations consist of records of 

stage, measurements of discharge, and general information used to

FIGURE 1. Typical gaging station

supplement the gage heights and discharge measurements in determining the daily flow. The records of stage are obtained either from 

direct readings on a staff or chain 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. 

A typical gaging station, equipped with water-stage recorder and 

measuring cable and car, is shown in Figure 1.

From the discharge measurements rating tables are prepared that 

give the discharge for any stage. The application of the daily gage 

height to these rating tables gives the [daily discharge from which 

the monthly and yearly mean discharge is determined.

The data presented for each gaging station in the area covered by 

this report comprise a description of the station, a table giving records
4 SURFACE WATER SUPPLY, 1925, PART V

of discharge measurements, a table showing the daily discharge of 

the stream, and a table of monthly and yearly discharge and run-off.

If the base data are insufficient to determine the daily discharge, 

tables giving daily gage height and records of discharge measurements 

are published.

The description of the station gives, in addition to statements 

regarding location and equipment, information in regard to any 

condition that may affect the permanence of the stage-discharge 

relation, covering such subjects as the occurrence of ice, the use of 

the stream for log driving, shifting of control, and the cause and 

effect of backwater; it gives also information as to diversions that 

decrease the flow at the gage, artificial regulation, maximum and 

minimum recorded stages, and the accuracy of the records.

The table of daily discharge gives, in general, the discharge in 

second-feet corresponding to the mean of the gage heights read each 

day. At stations on streams subject to sudden or rapid diurnal 

fluctuation the discharge obtained from the rating table and mean 

daily gage height may not be the true mean discharge for the day. 

If such stations are equipped with water-stage recorders the mean 

daily discharge may be obtained by averaging discharge at regular 

intervals during the day or by using the discharge integrator, an 

instrument operating on the principle of the planimeter and containing as an essential element the rating curve of the station.

In the table of monthly discharge the column headed "Maximum" 

gives the mean flow 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 per second during the month. On this 

average flow computations recorded in the remaining columns, which 

are defined on page 2, are based.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily (1) on the 

permanence of the stage-discharge relation and (2) on the accuracy 

of observation of stage, measurements of flow, and interpretation of 

records.

A paragraph in the description of the station gives information 

regarding the (1) permanence of the stage-discharge relation, (2) precision with which the discharge rating curve is defined, (3) refinement 

of gage readings, (4) frequency of gage readings, and (5) methods of 

applying the daily gage height to the rating table to obtain the daily 

discharge.
PUBLICATIONS 5*

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," 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 monthly mean for any station may represent with high accuiacy 

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 J/ 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. All figures representing "second-feet per square mile" and "run-off in inches" 

published by the Geological Survey in earlier reports should be used 

with caution because of possible inherent but unknown sources of 

error.

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 

stations must first be satisfied. To give an idea of the amount of 

prior appropriations, a paragraph on diversions is presented in each 

station description. The figures given can not be considered exact 

but represent the best information available.

The table of monthly discharge gives only a general idea of the 

flow at the station and should not be used for other than preliminary 

estimates; the tables of daily discharge allow 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.

PUBLICATIONS

Investigation of water resources by the United States Geological 

Survey has consisted in large part of measurements of the volume 

of flow of streams and studies of the conditions affecting that flow, 

but it has comprised also investigation of such closely allied subjects 

as irrigation, water storage, water powers, underground waters, and 

quality of waters. Most of the results of these investigations have 

been published in the series of water-supply papers, but some have 

appeared in the bulletins, professional papers, monographs, and 

annual reports.

8 SURFACE WATER SUPPLY, 1925, PAET V

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

over a series of years, and miscellaneous measurements at many points 

other than regular gaging stations have been made each year. 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 1925. 

The data for any particular station will be found in the reports covering the years during which the station was maintained. For example,

GAGING-STATION RECORDS

HUDSON BAY DRAINAGE BASIN

ST. MARY RIVER NEAR BABE, MONT.

LOCATION. In SE. ^ sec. 27, T. 36 N., R. 14 W., above headworks of St. Mary

Canal and 1 mile east of Babb, Glacier County, on Blackfeet Indian

Reservation. 

DRAINAGE AREA. 278 square miles (includes area of Swiftcurrent Creek above

point of diversion into St. Mary Lake; measured on topographic maps). 

RECORDS AVAILABLE. April 9, 1902, to September 30, 1925, when station was

discontinued. 

GAGE. Stevens water-stage recorder on right bank 20 feet above diversion dam;

referenced to staff gage which records head over crest. Recorder inspected

and staff gage read by S. M. Funk.

DISCHARGE MEASUREMENTS. Made from cable 500 feet above dam. 

CHANNEL AND CONTROL. Channel practically^permanent. Banks high and not

subject to overflow. Concrete diversion works for St. Mary Canal form

the control. 

EXTREMES OF DISCHARGE. Maximum discharge recorded during year, 4,220

second-feet May 25 and 26 (includes discharge of canal); minimum stage,

0.48 foot March 18 (discharge, 179 second-feet).

1902-1925: Maximum stage estimated at 9.4 feet June 5, 1908 (discharge,

7,980 second-feet); minimum discharge, 30 second-feet April 3-7, 1904. 

ICE. Stage-discharge relation seriously affected by ice. 

DIVERSIONS. Intake for United States Bureau of Reclamation St. Mary Canal

situated at left end of diversion dam. Tables of daily and monthly

discharge include the discharge of this canal. 

46678 29 2
12 SURFACE WATER SUPPLY, 1925, PAET V

REGULATION. Natural storage in St. Mary Lake. Swiftcurrent Creek is 

diverted into St. Mary Lake, the flow being regulated by gate operations at 

Sherburne Lake Reservoir.

ACCURACY. Stage-discharge relation permanent except when affected by iceRating curve well defined between 300 and 3,500 second-feet. Mean daily 

gage height obtained from recorder graph October 1 to November 6, May 

4-24, and June 3 to September 30. Observer's readings to hundredths once 

daily used January 27, February 28, March 18 and 31, April 6 and 18, and 

May 25 to June 2. Daily discharge ascertained by applying mean daily 

gage height to rating table and adding flow in canal for days when the canal 

was in operation. Records good.

The diversion dam below the gaging station was constructed by the United 

States Bureau of Reclamation for the purpose of diverting water from St. Mary 

River into St. Mary Canal, which carries water across the divide into North 

Fork of Milk River. The water then flows in the channel of Milk River through 

Canada and is finally used for irrigation in the Milk River Valley in Montana. 

The present capacity of the diversion canal is about 850 second-feet. A storage 

reservoir is provided on Swiftcurrent Creek by a dam at the outlet of Sherburne 

Lake. By means of a diversion channel connecting Swiftcurrent Creek and 

Lower St. Mary Lake the run-off from Swiftcurrent Creek is made available for 

diversion through St. Mary Canal.

The following discharge measurements of flow over the diversion dam were 

made:

June 6, 1925: Gage height, 1.80 feet; discharge, 2,110 second-feet.

June 21, 1925: Gage height, 2.10 feet; discharge 2,900 second-feet.

Daily discharge, in second-feet, of St. Mary River near Babb, Mont., for the year 

ending September 80, 1925

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 8.9 feet June 

9 (discharge, 3,400 second-feet); minimum stage, 2.95 feet October 2 

(discharge, 8 second-feet).

1909-1918; 1920-1925: Maximum open-water stage recorded, 12.2 feet 

April 19-21, 1916 (discharge, 7,040 second-feet). Minimum discharge, no 

flow July 17 and August 27, 1911.

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. A short distance above station is a dam owned by Hanson & 

Barzen Milling Co. and city lighting plant. The variation in load on the 

turbines due to operation of lighting plant (at night) and of the mill (chiefly 

during the day) causes fluctuations in stage at gage.

ACCURACY. Stage-discharge relation fairly permanent except as affected by ice. 

Rating curve well defined above and poorly defined below 400 second-feet. 

Gage read to half-tenths once daily during summer and two or three times 

weekly during winter, but owing to regulation the gage reading at low stages 

may not accurately represent the mean daily gage height. Daily discharge 

ascertained by applying daily gage height to rating table. Open-water 

records at high stages, good; at medium and low stages, poor. Winter 

records poor.

The following discharge measurements were made: 

April 15, 1925: Gage height, 4.11 feet; discharge, 295 second-feet. 

June 18,1925: Gage height, 6.87 feet; discharge, 1,530 second-feet. 

August 21,1925: Gage height, 3.83 feet; discharge, 166 second-feet.

BED LAKE RIVEE AT CBOOKSTON, MINN.

LOCATION. In sec. 30, T. 150 N., R. 46 W., at Sampson's Addition highway 

bridge in Crookston, Polk County, a quarter of a mile below dam and 

power house of Crookston Light, Water & Power Co. No tributaries 

enter within several miles.

DRAINAGE AREA. 5,320 square miles.

RECORDS AVAILABLE. May 19, 1901, to September 30,^925.

GAGE. Chain gage attached to middle span of bridge; read by J. A. McLean. 

Zero of gage is 833.54 feet above sea level. *
HUDSON BAY DBAINAGE BASIN 25

DISCHAEGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of silt, gravel, and small boulders; 

control not well defined. One channel at all stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 13.5 feet 

June 9 (discharge, 7,550 second-feet); minimum discharge probably occurred 

during winter.

1901-1925: Maximum discharge recorded, 14,700 second-feet July 5, 1919; 

minimum discharge, 10 second-feet, by discharge measurement January 27, 

1912. The flow is controlled to such an extent that the minimum discharge 

has no bearing on minimum natural flow.

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. Diurnal fluctuation in stage, particularly during low water, is 

caused by operation of power plant immediately above station and by 

another plant 8 miles above. As the storage at these plants is small the 

mean monthly flow should represent nearly the natural flow.

ACCURACY. Stage-discharge relation not permanent; affected by ice and by 

shifting control. Rating curve well defined above 1,000 second-feet and 

poorly defined below. Gage read to tenths once daily. At low stages the 

mean daily gage height may be considerably in error on account of regulation. Records from July 16 to September 30 withheld from publication 

because recorded gage readings did not represent the mean daily gage height. 

Daily discharge ascertained by applying daily gage height to rating table. 

Open-water records fair for discharge above 1,000 second-feet; poor below. 

Winter records poor.

KAWISHIWI RIVER NEAR WINTON, MINN.

LOCATION. In lot 3, section 20, T. 63 N.,1 R. 11 W., at power plant of Minnesota 

Power & Light Co. just above Fall Lake and 3,000 feet below Garden Lake, 

near west line of Lake County, and 2^ miles east of Winton, St. Louis 

County.

DRAINAGE AREA. 1,200 square miles.

RECORDS AVAILABLE. June 21, 1905, to June 30, 1907; October 14, 1912, to 

September 30, 1919; and September 1, 1923, to September 30, 1925.

DISCHARGE. Discharge of turbines in second-feet corresponding to gate opening 

and head on wheels is determined for each hour during the day. From 

this data is computed the mean daily discharge through the plant. Water 

is seldom wasted over the dam, but when it is wasted the quantity is 

computed from theoretical formulas and added to the flow through the 

wheels.

EXTREMES OP DISCHARGE. Maximum mean daily discharge recorded during year 

ending September 30, 1924, 916 second-feet June 13; minimum discharge, 

no flow a number of times during year.

Maximum mean daily discharge recorded during year ending September 30, 

1925, 2,430 second-feet October 16; minimum discharge, no flow a number 

of times during year.

1905-1907, 1912-1919, and 1923-1925: Maximum discharge recorded, 

5,370 second-feet April 30 and May 7, 1916; minimum discharge, no flow a 

number of times in 1905, 1906, 1907, 1923, 1924, and 1925. Maximum and 

minimum discharge are the result of regulation.

REGULATION. Practically the entire discharge of the stream is controlled by 

reservoirs in the interest of power development.

ACCURACY. Computations of discharge through the wheels are based on a calibration made in December, 1924, by the salt-velocity method. Records 

good, except on rare occasions when water is wasted over the dam, for which 

the records are fair.

COOPERATION. Records furnished by Minnesota Power & Light Co.

UPPER MISSISSIPPI RIVER BASIN

MISSISSIPPI RIVER ABOVE SANDY RIVER, NEAR IIBBY, MINN.

LOCATION. In SE. J^ sec. 2, T. 50 N., R. 24 W., just above mouth of Libby 

Creek, 4 miles north of Libby post office, Aitkin County, and 4 miles above 

mouth of Sandy River.

DRAINAGE AREA. 4,560 square miles (revised).

RECORDS AVAILABLE. August 1 to September 30, 1925. From September 1, 

1895, to September 30, 1915, records were collected by the United States 

Engineer Corps at a station 4 miles downstream.

GAGE. Gurley water-stage recorder installed in a timber well and shelter on left 

bank; inspected by A. Buchholtz,

DISCHARGE MEASUREMENTS. Made from boat near gage.

CHANNEL AND CONTROL. Bed composed of s,and and silt; control not well defined; 

banks of medium height 'and will seldom be overflowed.

EXTREMES OF DISCHARGE. Maximum mean daily stage recorded, 22.13 feet September 19 (discharge, 2,170 second-feet); minimum mean daily stage recorded, 

18.90 feet August 2 (discharge, 660 second-feet).

REGULATION. The Itasca Paper Co. operates a power plant at Grand Rapids 

40 miles above the station, but the effect of regulation from this plant is 

very slight. Flow of river is controlled by three Government reservoirs at 

Lake Winnibigoshish, Leech Lake, and Pokegama Lake to increase lowwater open-season flow in the interests of navigation. The total capacity 

of these three reservoirs is 82 billion cubic feet.

ACCURACY. Rating curve fairly well defined. Operation of water-stage recorder 

satisfactory during the period. Daily discharge ascertained by applying to 

rating table, mean daily gage height determined by inspection of recorder 

graph. Records good.

MISSISSIPPI RIVER NEAR ROYA1TON, MINN.

LOCATION. In lot 2, sec. 20, T. 39 N,, R. 32 W., at power plant of Minnesota 

Power & Light Co., 5 miles northwest of Royalton, Morrison County, and 

5 miles below mouth of Swan River. Station was moved October 1, 1924, 

from highway bridge 3 miles downstream from present site. Drainage area 

practically the same at the two sites.

DRAINAGE AREA. 11,600 square miles.

RECORDS AVAILABLE. March 8, 1924, to September 30, 1925.

DISCHARGE. Discharge of the turbines in second-feet corresponding to the gate 

opening and head on the wheels is determined for each hour during the day. 

From this data is computed the mean daily discharge through the plant. 

The waste, when any, is computed from a calibration of the discharge 

through the Taintor gates at various openings and is added to the discharge 

through the wheels.
32 SURFACE WATER SUPPLY, 1925, PART V

EXTREMES OF DISCHARGE. Maximum mean daily discharge recorded during the 

year, 5,230 second-feet June 16, minimum mean daily discharge, 351 secondfeet January 4.

1924-1925: Maximum discharge recorded, .7,640 second-feet August 7, 

1924; minimum discharge that of 1925.

REGULATION. Considerable diurnal fluctuation is caused by operation of the 

power plant at which the station is situated and that of another plant at 

lattle Falls. The flow of the river is controlled by Government reservoirs 

on the upper river for the purpose of increasing the low-water open-season 

flow in the interests of navigation.

ACCURACY. Computation of discharge through plant based on manufacturer's 

rating of wheels. Computation of waste based on calibration of Taintor 

gates. Records good for low and medium stages; fair for high stages.

COOPERATION. Records of daily discharge furnished by Minnesota Power & 

Light Co.

MISSISSIPPI RIVER AT ELK RIVER, MHOT.

ILocATiON. In sec. 3, T. 121 N., R. 23 W., at highway bridge in Elk River, 

Sherburne County, 2,500 feet below mouth of Elk River.

DRAINAGE AREA. 14,500 square miles.

RECORDS AVAILABLE. July 22, 1915, to September 30, 1925.

 GAGE. Chain gage bolted to handrail of bridge on downstream side near right 

bank; read by W. H. Ebner.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

OHANNEL, AND CONTROL. Bed composed of sand and gravel; control not well 

denned. Banks high and not subject to overflow.

.EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.56 feet at 

7.25 a. m. June 14 (discharge, 6,280 second-feet); minimum discharge estimated because of ice, 867 second-feet January 3.

1915-1925: Maximum open-water stage recorded, 10.8 feet April 7, 1916 

(discharge, 27,000 second-feet); minimum discharge that of January 3,1925.

ICE. Stage-discharge relation seriously affected by ice.

.REGULATION. Nearest dam above station is at St. Cloud, 40 miles upstream. 

An observed systematic diurnal fluctuation at gage of about 0.1 foot is 

doubtless due to regulation at St. Cloud, but most of the effect of regulation 

is equalized before reaching station. The flow of the river is controlled by 

Government dams on the upper river for the purpose of increasing the lowwater open-season flow in the interests of navigation.

.ACCURACY. Stage-discharge relation permanent except as affected by ice. 

Rating curve well defined. Gage read to hundredths twice daily. Daily 

discharge ascertained by applying mean daily gage height to rating table 

except as explained in footnote to table of daily discharge. Open-water 

records excellent; winter records fair.

COOPERATION. Gage-height record furnished by United States Engineer Corps.

The following discharge measurement was made:

June 22,1925: Gage height, 4.08 feet; discharge, 4,720 second-feet.

UPPER MISSISSIPPI RIVER BASIN 35

MISSISSIPPI RIVER AT ST. PAUI, MINN.

LOCATION. At Chicago Great Western Railway bridge near foot of Robert 

Street, St. Paul, Ramsay County, 6 miles below mouth of Minnesota River.

DRAINAGE AEEA. 35,700 square miles.

RECOBDS AVAILABLE. March 22, 1887, to September 30, 1925. Observations of 

stage were begun in 1873 by United States Signal Service and continued by 

United States Weather Bureau. Many discharge measurements made prior 

to 1900 by United States Engineer Corps.

GAGE. Chain gage which had previously been situated on downstream handrail 

of the Chicago Great Western Railway bridge Was moved July 25, 1924, to 

handrail of temporary highway bridge at foot of Jackson Street, and set to 

same datum as formerly used; read by employee of United Spates Weather 

Bureau. On March 18, 1925, an Au water-stage recorder was installed in 

wooden well and shelter at upstream end of shear fence protecting left abutment of Chicago Great Western Railway bridge. Both gag«s referred to 

same datum.

DISCHARGE MEASUEEMENTS. Made from Wabasha Street Bridge 1,000 feet 

above gage.

CHANNEL AND CONTROL. Channel fairly permanent. Control not well defined. 

Some backwater has been caused during the year by obstructions in the 

river due to construction of the new Robert Street Bridge. Banks moderately high; not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.33 feet at 

1 p.m. June 20 (discharge, 16,800 second-feet); minimum stage recorded, 

 2.5 feet January 7 (discharge, 1,130 second-feet).

1887-1925: Maximum stage recorded, 18.0 feet April 6, 1897 (discharge, 

80,800 second-feet); highest known discharge occurred July 22, 1867, and 

amounted to 117,000 second-feet; minimum discharge, 1,060 second-feet 

February 4, 1895.

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. During low water, regulation of the flow through turbines at the 

Government dam just above the mouth of Minnesota River causes diurnal 

fluctuation of stage at St. Paul. Flow is regulated by Government reservoirs on the headwaters at Lake Winnibigoshish, Leech Lake, Pokegama 

Lake, Sandy Lake, Pine River, and Gull Lake to increase the low-water 

openrseason flow in the interests of navigation, but the effect of this regulation is very gradual at St. Paul.

ACCURACY. Stage-discharge relation fairly permanent during the year. Rating 

curve poorly defined. Gage readings to tenths once daily used October 1 

to March 17; recording-gage records used March 18 to September 30. 

Daily discharge ascertained by applying to rating table daily or mean daily 

gage height determined by inspection of recorder graph except as noted in 

footnote to daily-discharge table. Records prior to March 18, poor; after 

March 18, fair.

COOPERATION. Gage-height record October 1,1924, to March 17,1925, furnished 

by United States Weather Bureau.

UPPEE, MISSISSIPPI BIVEB BASIN

MINNESOTA BIVEB NEAR MONTEVIDEO, MTBTN. <

LOCATION. In sec. 17, T. 117 N., R. 40 W., at highway bridge 1 mile south of 

Montevideo, Chippewa County, 500 feet below mouth of Chippewa River.

DRAINAGE AREA. 6,300 square miles.

RECORDS AVAILABLE. July 22, 1909, to September 30, 1925.

GAGE. Chain gage attached to upstream handrail of bridge near left bank; 

read by Elizabeth Hendricks.

DISCHARGE MEASUREMENTS. Made from upstream side of bridge.

CHANNEL AND CONTROL. Bed composed of heavy gravel and sand; permanent. 

There is a slight riffle just below gage, but control section is not well 

defined. Banks will be overflowed at a stage of 14 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.05 feet 

June 26-28 (discharge, 1,300 second-feet); minimum stage recorded, 1.76 

feet at 6 p. m. August 29 (discharge, 49 second-feet).

1909-1925: Maximum stage recorded, about 18.85 feet June 25, 1919 

(discharge, about 22,000 second-feet); minimum discharge, 6.8 second-feet» 

measured by current meter February 9, 1912.

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. No regulation on Minnesota River above station. Regulation 

of Chippewa River at plant of Chippewa Milling Co. in Montevideo produces 

a slight fluctuation in stage of Minnesota River at gage.

ACCURACY. Stage-discharge relation permanent. Rating curve fairly well 

defined. Gage read to quarter-tenths twice daily. Daily discharge ascertained by applying mean daily gage height to rating table. Records good.

The following discharge measurement was made:

June 24, 1925: Gage height, 6.52 feet; discharge, 1,170 second-feet.

Daily discharge, in second-feel, of Minnesota River near Montevideo, Minn., for the 

year ending September SO, 1925

MINNESOTA RIVER AT MANKATO, MIWW.

LOCATION. In sec. 7, T. 108 N., R. 26 W., at Main Street highway bridge in 

Mankato, Blue Earth County, 2 miles below mouth of Blue Earth River.

DRAINAGE AREA. 14,600 square miles.

RECORDS AVAILABLE. March 15, 1922, to September 30, 1925, at present site; 

May 20, 1903, to October 19, 1921, at Sibley Park 2 miles upstream. 

Drainage area practically the same at the two sites.

GAQE. Chain gage on downstream side of bridge over center of left channel 

until November 30, 1924. On March 20, 1925, an Au water-stage recorder 

was installed near left abutment of bridge at same datum as chain gage. 

Chain gage read and recorder inspected by J. J. Pihale.

DISCHARGE MEASUREMENTS. Made from bridge to which gage is attached.

CHANNEL AND CONTROL. Bed composed of sand and light gravel; shifting 

during high stages. Banks moderately high and not subject to overflow. 

Control poorly defined.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 13.1 feet at 

5 a. m. June 17 (discharge, 8,640 second-feet); minimum stage, 3.3 feet at 

11 p. m. September 2 (discharge, 133 second-feet).

1903-1925: Maximum stage recorded, 21.2 feet at old site at Sibley Park 

June 26, 1908 (discharge, 43,800 second-feet); minimum discharge, 89 

second-feet August 31 to September 2, 1911.

The highest known stage of the river occurred in 1881 and is shown in 

Mankato by a well-marked line about 27 feet above zero of Sibley Park 

gage (discharge, estimated 65,000 second-feet).

ICE. No records available during winter.

REGULATION. Nearest dam on Minnesota River is at Minnesota Falls, 140 

miles upstream. A dam on Blue Earth River at Rapidan, a few miles above 

mouth, controls the flow of that river, which is about 20 per cent of that at 

the Mankato station, and produces considerable daily fluctuation at gage, 

amounting at times to more than 1 foot.

ACCURACY. Stage-discharge relation has probably been permanent during the 

year. Rating curve well defined between 96 and 4,620 second-feet; extended 

above. Chain gage read to tenths once daily during October and November, 1924. Operation of water-stage recorder satisfactory March 20 to 

September 30. Daily discharge ascertained by applying to rating table 

daily or mean daily gage height determined by inspection of recorder graph. 

Records for October and November, fair; March 20 to September 30, good.
UPPER MISSISSIPPI RIVEB BASIN

COOPERATION. Gage-height records October 1 to November 30 furnished by 

the United States Weather Bureau.

The following discharge measurement was made:

June 25, 1925: Gage height, 8.86 feet; discharge, 4,480 second-feet.

Daily discharge, in second-feet, of Minnesota River at Mankato, Minn., for the year

UPPER MISSISSIPPI RIVER BASIN 45

ST. CEOIX RIVER NEAR ST. CROIX FALLS, WIS.

'LOCATION. In sec. 18, T. 34 N., R. 18 W., at power plant of Northern States 

Power Co., on Wisconsin side of St. Croix River near St. Croix Falls, 

Polk County.

DBAINAGE ABBA. 5,930 square miles.

RECORDS AVAILABLE. January 1, 1910, to September 30, 1925. Discharge 

measurements for 1903 published in Water-Supply Paper 98, under St. Croix 

River near Taylors Falls, Minn. Records from January 10,1902, to December, 1909, published in "Report of water-resources investigation of Minnesota, 1909-1912" by Minnesota State Drainage Commission.

".DISCHARGE. Determinations of discharge based on kilowatt output of generators 

and exciters plus flow over spillway, considered as a weir.

^EXTREMES OF DISCHARGE. Maximum mean daily discharge recorded during 

year, 6,820 second-feet October 1; minimum mean daily discharge, 472 

second-feet February 8.

1902-1905; 1910-1925: Maximum discharge recorded, 35,800 second-feet 

March 26, 1920; minimum discharge, 75 second-feet July 17, 1910 (caused 

by regulation).

3R,EGtrLATioN. Low-water flow controlled by operation of gates of power plant. 

Nevers Dam, 10 miles above station, which was for some time in such poor 

condition that little regulation could be effected by it, was repaired September 25, 1924, and since that time has been used to regulate the flow at 

the St. Croix Falls power plant.

.ACCURACY. During June and July, 1925, a test of efficiency of the wheels at 

this plant was made by G. E. Laughland, hydraulic engineer for the 

Byllesby Engineering & Management Corporation, using the salt titration 

method. The discharge determined by this method was 5 per cent less than 

that given by the old calibration curves. No revision of the calibration 

curves was made when the records for the year ending September 30, 1925, 

were prepared. Records good.

 COOPERATION. Records furnished by the Northern States Power Co.

Daily discharge, in second-feet, of St. Croix River near St. Croix Falls, Wis., for the 

year ending September 80, 1925

APPLE RIVER NEAR SOMERSET, WIS.

LOCATION. In sec. 21, T. 31 N., R. 19 W., at power plant of Northern States 

Power Co., 3J^ miles below Somerset, St. Croix County, and 2 miles abovemouth.

DRAINAGE AREA. 550 square miles (measured on map issued by WisconsinGeological and Natural History Survey, edition of 1911).

RECORDS AVAILABLE. January, 1901, to September 30, 1925.

GAGE. Vertical staff gages are used in determining head on wheels.

DETERMINATION OF DISCHARGE. The discharge through plant is determined: 

from tables based on data collected in a series of tests, using a sharp-crested 

weir, made in September, 1920. Daily discharge of the turbines is computed from hourly observations of the kilowatt output and the number of 

wheels in operation. To this is added leakage through the average number 

of wheels idle each day, the sum giving the daily flow through power house. 

Water is seldom wasted over spillway of dam, but when it is wasted the 

quantity is computed from weir formula and added to flow through plant. 

Records do not include the constant leakage of 3 second-feet through gate 

and flashboards.

EXTREMES OF DISCHARGE. Maximum mean daily discharge during year, 598 

second-feet March 24; minimum mean daily discharge, 25 second-feetAugust 27. *

1904-1924: Maximum mean daily discharge recorded, 2,280 second-feet 

in June, 1905; minimum mean daily discharge, 20 second-feet June 26,1921.. 

Owing to regulation computed minimum discharge has no bearing on natural minimum flow.

REGULATION. There are a number of power plants above station. Thepondage of these plants is small, and though daily flow may be eontrolledto some extent, mean monthly flow probably represents nearly the natural 

flow.

COOPERATION. Records furnished by the Northern States Power Co.

No discharge measurements were made at the station during year.

50 SURFACE WATER SUPPLY, 1925, PART V

CHIPPEWA BITER AT BISHOPS BRIDGE, NEAR WINTER, WIS.

LOCATION. -In sec. 23, T. 39 N., R. 6 W., at highway bridge 3 miles downstream 

from Chippewa Reservoir dam and 4 miles by road northwest of Winter, 

Sawyer County.

DRAINAGE AREA. 775 square miles (measured on map issued by Wisconsin 

Geological and Natural History Survey, edition of 1911).

RECORDS AVAILABLE. February 23, 1912, to September 30, 1925.

GAGE. Chain gage fastened to bridge; read by Mrs. Ludvig Larson.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by 

wading.

CHANNEL AND CONTROL. Bed composed of gravel; free from vegetation; practically permanent. Control is head of rapids 1,000 feet below gage. One 

channel at all stages. Banks not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.20 feet 

February 14 (discharge, 1,680 second-feet); minimum stage, 3.25 feet April 

17-20 and May 1-5 (discharge, 14 second-feet). Both maximum and 

minimum stages are the result of regulation.

1912-1925: Maximum stage recorded, 9.56 feet April 22,1916 (discharge, 

6,940 second-feet); minimum stage recorded, that of 1925.

ICE. Stage-discharge relation not seriously affected by ice.

REGULATION. In April, 1923, the Chippewa Reservoir owned by the Northern 

States Power Co. was put into operation. This reservoir is situated just 

below the confluence of East and West Forks of Chippewa River 3 miles 

above station and has a capacity of 10 billion cubic feet. Operation of 

this reservoir regulates the entire flow of the stream at the station in the 

interest of power developments below. There is also a reservoir 16 miles 

above station with a capacity of 550 million cubic feet.

ACCURACY. Stage-discharge relation permanent; not affected by ice during 

year. Rating curve well defined above and fairly well defined below 200 

second-feet. Gage read to half-tenths twice daily. Daily discharge 

ascertained by applying mean daily gage height to rating table. Records 

excellent, except during low stages for which they are good.

The following discharge measurements were made:

October 8, 1924: Gage height, 3.64 feet; discharge, 48.0 second-feet.

April 27, 1925: Gage height, 3.44 feet; discharge, 25.7 second-feet.

Daily discharge, in second-feet, of Chippewa River at Bishops Bridge, near Winter,

CHIPPEWA EIVEE AT CHIPPEWA FALLS, WIS. 

XOCATION. In SE. 14 sec. 6, T. 28 N., R. 8 W., at highway bridge at Chippewa

Falls, Chippewa County, 2,500 feet below mouth of Duncan Creek. 

DRAINAGE AREA. 5,600 square miles. 

RECORDS AVAILABLE. June 22, 1888, to September 30, 1925.

 GAGE. Gurley water-stage recorder on web between caisson piers supporting

first right-hand span; inspected by F. N. Leslie. 

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

-CHANNEL AND CONTROL. Bed composed of heavy gravel; fairly permanent. 

Banks high and are seldom overflowed.

^EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.2 feet at 

10 a. m. June 15 (discharge, 20,800 second-feet); minimum mean daily 

discharge, 400 second-feet September 5.

1888-1925: Maximum stage recorded, 26.03 feet December 6, 1896; 

September 10, 1884, a stage of 26.94 feet was reached. The extreme high 

stages in 1884 and 1896 were probably caused in part by backwater from 

log jams and the volume of discharge was probably considerably less than 

the stage would indicate if the channel had been unobstructed. Exclusive 

of these floods, the maximum stage recorded was 17.0 feet March 27, 1920 

(discharge, 78,000 second-feet); minimum discharge recorded, about 40 

second-feet February 4, 1917. Minimum flow was caused by regulation.

ICE. Stage-discharge relation not seriously affected by ice.

REGULATION. Flow past station at low and medium stages controlled to a 

considerable extent by operation of Wissota power plant of the Northern 

States Power Co. This plant also causes large diurnal fluctuation. Owing to 

operation of storage reservoirs on Chippewa and Flambeau Rivers the flow 

at the station is not natural.

ACCURACY. Stage-discharge relation practically permanent. Rating curve well 

defined above and fairly well defined below 2,000 second-feet. Operation of 

water-stage recorder satisfactory except as noted in footnote to table of daily 

discharge. Mean daily discharge obtained by means of discharge integrator. 

Records at medium and high stages good; at low stages fair.

The following discharge measurements were made:

January 2^1925: Gage height, 2.00 feet (stage-discharge relation affected by 

ice); discharge, 4,400 second-feet.

January 30, 1925: Gage height, 1.68 feet; discharge, 4,300 second-feet. 

April 17, 1925: Gage height, 2.58 feet; discharge, 6,430 second-feet.

TJPPEB MISSISSIPPI RIVER BASIN

FLAMBEAU RIVER NEAR BUTTERNUT, WIS.

LOCATION. In lot 10, sec. 28, T. 41 N., R. 1 E., 6 miles southeast of Butternut, 

Ashland County, and 7 miles upstream from Park Falls.

DRAINAGE AREA. 660 square miles (measured on map issued by Wisconsin 

Geological and Natural History Survey, edition of 1911).

RECORDS AVAILABLE. July 30, 1914, to September 30, 1925.

GAGE. Chain gage supported by a built-up cantilever, attached to post set in 

right bank; read by Carl G. Elm.

DISCHARGE MEASUREMENTS. Made from cable 1,500 feet downstream from gage.

CHANNEL AND CONTROL. Bed at gage composed of mud and rock. Left bank 

is low and subject to overflow; right bank slopes back gradually to highwater mark. At cable site the bed is rock and banks are high. Control is 

at head of Schultz Rapids, 1,700 feet below gage; permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.06 feet 

April 25 (discharge, 940 second-feet); minimum stage, 0.25 foot September 

18 and 19 (discharge, 91 second-feet).

1914-1925: Maximum stage recorded, 9.0 feet April 22 and 23, 1916 

(discharge, 5,430 second-feet); minimum stage recorded that of September 

18 and 19, 1925.

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. Storage reservoirs, having an effective capacity of 1.15 billion 

cubic feet, are maintained by the Chippewa & Flambeau Improvement Co. 

on the headwaters of Flambeau River. A large reservoir was being con. 

structed during the year 9 miles above the gage, and although the minimum 

stage of September 18 and 19 may have been caused by a temporary holding 

of water at the dam the greater part of the low water in July, August, and 

September is believed to be natural flow.

ACCURACY. Stage-discharge relation permanent except as affected by ice. 

Rating curve well defined. Gage read to quarter-tenths once daily. Daily 

discharge ascertained by applying daily gage height to rating table except 

as indicated in footnote to table of daily discharge. Open-water records 

good; winter records fair.

FLAMBEAU RIVER NEAR IADYSMITH, WIS.

LOCATION. In sec. 35, T. 36 N., R. 5 W., at Big Falls power plant of Lake 

Superior District Power Co., 6 miles northeast of Tony and 12 miles northeast of Ladysmith, Rusk County.

DRAINAGE AREA. 1,910 square miles (measured on map issued by Wisconsin 

Geological and Natural History Survey, edition of 1911).

RECORDS AVAILABLE. October 1, 1923, to September 30, 1925. From January 

2, 1914, to September 30, 1923, at a station 8 miles below present site, and 

February 15, 1903, to December 2, 1906, at Ladysmith, 14 miles downstream.

DISCHARGE MEASUREMENTS. Made from boat or by wading.
T7PPEE MISSISSIPPI EIVEE BASIN 57

DETERMINATION OP IJISCHARGE. Daily discharge computed from hourly determinations of flow through each turbine based on kilowatt output, and the 

flow through waste gates and over spillway as computed from hourly determinations based on theoretical formulas.

EXTREMES OF DISCHARGE. Maximum mean daily discharge recorded during 

year, 3,390 second-feet April 25; minimum mean daily discharge, 176 secondfeet August 30.

1903-1906; 1914-1925; Maximum discharge recorded, 19,500 second-feet 

April 11, 1922; minimum discharge, that of 1925. The minimum discharge 

was caused by regulation.

REGULATION. Diurnal fluctuation is caused by operation of power plant at 

which station is situated. The Chippewa & Flambeau Improvement Co. 

operates storage reservoirs on the headwaters having an effective capacity 

of 1.15 billion cubic feet. Weekly fluctuations at station are caused by 

operation of power plants at Park Falls and storage reservoirs.

ACCURACY. Computation of discharge through turbines and waste gates is 

based on a series of discharge measurements made by engineers of the Survey in October, 1925. Records of discharge through turbines are good. 

Computation of waste is poor. Records good except at high stages, for 

which they are fair.

COOPERATION. Power-house data is furnished by the Lake Superior District 

Power Co.

60 SURFACE WATER SUPPLY, 1925, PART V

EAU CLAIRE RIVER NEAR AUGUSTA, WIS.

LOCATION. In sec. 12, T. 26 N., R. 6 E., at Trouble Water Bridge, 7 miles 

northeast of Augusta, Eau Claire County. South Fork of Eau Claire River 

enters 4 miles above station.

DRAINAGE AREA. 500 square miles (measured on map issued by Wisconsin 

Geological and Natural History Survey, edition of 1911).

RECORDS AVAILABLE. July 16, 1914, to September 30, 1925.

GAGE. Chain gage on downstream side of bridge; read by Albert Wagner.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed at bridge and above is sandy and shifting. A 

short distance below gage channel narrows, and a rock outcrop overlain 

with large boulders forms control. Banks high and not subject to overflow.

ICE. Stage-discharge relation seriously affected by ice.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.92 feet 

June 13 (discharge, 4,460 second-feet); minimum discharge, estimated 20 

second-feet February 16-18 and February 28 to March 3 (stage-discharge 

relation affected by ice).

1914-1925: Maximum open-water stage recorded, 12.0 feet at 9 a. m. 

March 27, 1920 (discharge, 8,720 second-feet); minimum discharge, 3.5 

second-feet January 27, 1918, from discharge measurement made through 

complete ice cover.

ACCURACY. Stage-discharge relation changed somewhat during summer. Rating curve fairly well defined. Gage read to quarter-tenths once daily. 

Daily discharge for the open-water periods ascertained by applying daily 

gage height to rating table, except from August 1 to September 30, when 

shifting-control method was used. Records fair.

BED CEDAR RIVEB NEAR COIFAX, WIS.

LOCATION. In sec. 27, T. 30 N., R. 11 W., at highway bridge 4J^j miles north of 

Coif ax, Dunn County. Trout Creek enters 3 3^ miles above station and 

Hay River enters 11 miles below.

DRAINAGE AREA. 1,100 square miles (measured on map issued by Wisconsin 

Geological and Natural History Survey, edition of 1911.

RECORDS AVAILABLE. March 19, 1914, to September 30, 1925.

GAGE. Chain gage attached to downstream side of bridge. On September 16, 

1925, a Friez water-stage recorder was installed in a wooden well and shelter 

150 feet above bridge. Chain gage read and recorder inspected by Oilman 

Loftsgaard.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.
62 SURFACE WATER SUPPLY, 1925, PART V

CHANNEL AND CONTROL. Bed composed of rock and gravel; small amount of 

grass growth during summer. Left bank high and not subject to overflow; 

right bank medium high and may be overflowed during extremely high 

water. Control poorly defined.

EXTREMES OF DISCHARGE. Maximum discharge recorded during year, 3,120 

second-feet, at 8.30 a. m. March 20; minimum stage, 0.90 foot August 29-31 

(discharge, 260 second-feet).

1914-1925: Maximum stage recorded, 6.95 feet at 8 a. m. March 26,1920 

(discharge, 7,610 second-feet); minimum open-water stage recorded, 0.61 

foot December 18,1921 (discharge, about 233 second-feet), apparently caused 

by temporary holding back of water by ice.

ICE. Stage-discharge relation affected by ice.

REGULATION. The following dams and reservoirs 2 are used to regulate the flow 

in Red Cedar River: Long Lake, Cedar Lake, Birch Lake, and Bear Lake; 

total capacity, 1,425 million cubic feet. Owing to operation of these 

reservoirs the flow at the station is not natural.

ACCURACY. Stage-discharge relation slightly affected by backwater from dam 

at Colfax and by growth of grass in channel. Rating curve well defined above 

500 second-feet and poorly defined below. Gage read to hundredths once 

daily until September 12; mean daily gage height obtained from recorder 

graph September 16-30. Daily discharge ascertained by applying daily or 

mean daily gage height to rating table except from July 1 to September 30, 

when shifting-control method was used, and as explained in footnote to 

daily-discharge table. Open-water records fair; winter records poor.

BLACK RIVER AT NEHISVHIE, WIS.

LOCATION. In sec. 15, T. 24 N., R. 2 W., at lower highway bridge in Neillsville, 

Clark County. O'Neill Creek enters from left 1 mile above gage, and 

Cunningham Creek, also from left, 1J^ miles below.

DRAINAGE AREA. 774 square miles (measured on map issued by Wisconsin Geological and Natural History Survey, edition of 1911).

RECORDS AVAILABLE. April 6,1905, to March 31,1909; December 11,1913, to 

September 30, 1925.

G^AGE. Chain gage on downstream side of bridge; read by A. Bissell.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by wading.

CHANNEL AND CONTROL. Bed composed of heavy gravel and rock. Control at 

head of rapids, a few hundred feet below gage. Banks high and rocky; not 

subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 8.45 feet at 4 

a. m. June 14 (discharge, 4,220 second-feet); minimum discharge, estimated 

15 second-feet January 2 (stage-discharge relation affected by ice).

1905-1909; 1913-1925: Maximum stage recorded, 19.8 feet June 6,1905 

(discharge, about 29,400 second-feet); minimum discharge, estimated 5 

second-feet during month of February, 1918, when stage-discharge relation 

was affected by ice.

The flood of October 6, 1911, probably exceeded 29,000 second-feet, 

although data are not available regarding stage at gage section during this 

flood.

I<f!E. Stage-discharge relation seriously affected by ice.

REGULATION. Several dams on Black River and tributaries upstream from 

Neillsville are used to create a head for developing power. Operation of 

these plants causes a slight diurnal fluctuation at gage, especially during 

winter when flow is at a minimum.

AJCCURACY. Stage-discharge relation permanent except as affected by ice. Rating curve well defined. Gage read to quarter-tenths twice daily. Daily 

discharge ascertained by applying mean daily gage height to rating table 

except as explained in footnote to table of daily discharge. Open-water 

records good except at extremely low stages, for which they are fair; winter 

records poor.

Dutch Creek enters from right 6 miles above station.

DRAINAGE AREA. 412 square miles (measured on map issued by Wisconsin 

Geological and Natural History Survey, edition of 1911).

KISCORDS AVAILABLE. December 22, 1913, to September 30, 1925.

GAGE. Chain gage attached to concrete guardrail on upstream side of bridge; 

read by J. R. Carlson.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of heavy gravel and rock; free from 

vegetation. Right bank high and not subject to overflow; left bank above 

the gage low and subject to overflow at flood stages. Control for low 

stages is a rocky riffle with a fall of 6 inches, which is apparently drowned 

out at a stage of about 2.2 feet, causing a reversal in the rating curve. 

Control is filled in with silt which leaks through dam above, causing a 

shifting control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.22 feet at 7 

a. m. June 15 (discharge, 2,080 second-feet); minimum stage, 0.97 foot at 

6 p. m. May 24 (discharge, 110 second-feet).

1913-1925; Maximum stage recorded, 8.45 feet March 16, 1919 (discharge, about 3,620 second-feet); minimum discharge, estimated 90 secondfeet January 6, 1924 (stage-discharge relation affecte'd by ice).

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. Diurnal fluctuation at gage, amounting at low stages to from 

0.10 to 0.40 foot, is caused by operation of power plants, especially at 

Neshonoc Dam, a few miles above station.

CCURACY. Stage-discharge relation changed slightly during year. Rating 

curve well defined above 200 second-feet. Gage read to hundredths twice 

daily. Daily discharge ascertained by applying mean daily gage height to 

rating table except from March 12 to September 30, when shifting-control 

method was used. Open-water records fair; winter records poor.

UPPER MISSISSIPPI RIVER BASIN

WISCCKSDT 1I7EB AT WHIRIPOOL RAPIDS, NEAB RHINEIAHDEB, WIS.

71

. In sec. 4, T. 35 N., R. 8 E., at head of Whirlpool Rapids, 1 mile below 

outlet of Crescent Lake, 3 miles below dam and power plant of Wisconsin 

Valley Electric Co., and 10 miles southwest of Rhinelander, Oneida County.

!)HAINAGE AEEA. 1,160 square miles (measured on map issued by Wisconsin 

Geological and Natural History Survey, edition of 1911).

HECORDS AVAILABLE. September 15, 1915, to September 30, 1925. December 

1,1905, to September 30, 1915, records were collected at a station 3 miles 

upstream.

JAGE. Stevens continuous water-stage recorder on right bank; inspected by 

Clarence Jewell.

DISCHARGE MEASUREMENTS. Made from cable 150 feet above gage. 

'HANNEL AND CONTROL. Bed composed of heavy gravel and rock. Banks 

medium high and not subject to overflow. Control is head of rapids, 100 

feet below gage; well defined and permanent.

IXTREMES OF DISCHARGE. Maximum discharge recorded during year, 2,720 

second-feet (estimated from gage height at Hat Rapids); minimum stage 

0.80 foot at 4 a. m. September 30 (discharge, 212 second-feet).

1905-1915: Maximum discharge recorded, 4,890 second-feet August 11 ( 

1912; minimum discharge, no flow August 4 and September 15, 1907, and 

June 21 and July 5,1908.

1915-1925: Maximum stage recorded, 5.61 feet at 10 p. m. April 22, 1916 

(discharge, 5,250 second-feet); minimum stage, 0.65 foot at 8 p. m. July 7, 

1918 (discharge, 165 second-feet).

'. REGULATION. Blow is regulated by 14 reservoirs s and 3 power plants above the 

station. The aggregate capacity of reservoirs is 2.8 billion cubic feet during 

summer and 3.6 billion cubic feet during winter. Owing to operation of 

these storage reservoirs and power plants flow at the station is not natural.

ACCURACY. Stage-discharge relation permanent except as affected by ice and 

by growth of grass and moss on control. Rating curve well defined. 

Operation of water-stage recorder satisfactory during 87 per cent of openwater periods. Daily discharge for periods when water-stage recorder was 

in operation ascertained by applying to rating table mean daily gage height 

determined by inspection of recorder graph and for days of considerable 

fluctuation in stage by applying a correction that will approximate the 

results obtained by averaging hourly discharge. Shifting-control method 

used August 1 to September 30. Discharge for periods of no gage-height 

record obtained as indicated in footnote to daily-discharge table. Records 

good for periods whea water-stage recorder was in operation; other records 

poor.

28-30, May 21-23, 27-30, June 9-12,15-18, July 6-11, and Aug. 30-31; discharge ascertained by applying 

gage heights at Hat Rapids, 3 miles upstream, to a rating curve defined by three discharge measurements 

and extended by plotting discharge at Whirlpool Rapids, when available, against gage readings for the 

same days at Hat Rapids.

TIPPER MISSISSIPPI RIVER BASIN

WISCONSIN RIVEE AT MEBBTLL, WIS.

73

LOCATION. At highway bridge at east end of Merrill, Lincoln County, 1,000 feet 

below power house of Merrill plant of Wisconsin Valley Electric Co. and 

half a mile below mouth of Prairie River.

DRAINAGE AREA. 2,630 square miles (measured on Wisconsin Geological and 

Natural History Survey map, edition of 1911).

RECORDS AVAILABLE. November 16, 1902, to September 30, 1925.

GAGE. Gurley water-stage recorder on left bank; inspected by Otto F. Lueck.

DISCHARGE MEASUREMENTS. Made from bridge just above gage.

CHANNEL AND CONTROL. Bed composed of heavy gravel and rock; nearly 

permanent. Riffles on both sides of small island below gage probably 

constitute control. Banks fairly high and are seldom overflowed.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.60 feet at 

11 a. m. June 17 (discharge, 7,370 second-feet); minimum stage, 3.0 feet at 

2 a. m. July 26 (discharge, 440 second-feet), caused by regulation.

1902-1925: Maximum stage recorded, about 17.5 feet at 5 a. m. July 24, 

1912 (discharge, 45,000 second-feet); minimum stage, 2.45 feet September 

26, 1908 (discharge, about 90 second-feet).

REGULATION. Above the gaging station are 17 reservoirs,4 which are operated 

by the Wisconsin Valley Improvement Co. for the purpose of regulating 

flow in Wisconsin River. The aggregate capacity of these reservoirs is about 

6.25 billion cubic feet. In addition to the above reservoirs, there are on 

Wisconsin and Tomahawk Rivers above the station eight dams operated 

for power.

ACCURACY. Stage-discharge relation practically permanent except as affected 

by ice. Rating curve well defined above 1,000 second-feet. Operation of 

water-stage recorder satisfactory. Daily discharge determined by means 

of discharge integrator. Open-water records excellent; winter records 

good.

Railway and on State trunk highway No. 73 at Knowlton, Marathon County, 

1^4 miles below mouth of Big Eau Pleine River.

DRAINAGE AREA. 4,360 square miles (measured on map issued by Wisconsin 

Geological and Natural History Survey, edition of 1911).

RECOBDS AVAILABLE. July 13, 1921, to September 30, 1925. Gage heights 

May 1,1915, to July 12, 1921, published by United States Weather Bureau.

GAGE. Gurley water-stage recorder on left bank; inspected by W. T. Guenther.
UPPER MISSISSIPPI RIVER BASIN 75

DISCHARGE MEASXJBEMENTS. Made from downstream side of bridge, from boat, 

or by wading.

CHANNEL AND CONTBOL. Bed composed of sand and light gravel. Control not 

well defined; there is, however, a decided contraction of channel at an island 

2,500 feet below gage. Right bank high and is seldom overflowed; left 

bank of medium height and is overflowed at extreme flood stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 8.72 feet at 

8 a. m. July 14 (discharge, about 14,100 second-feet); minimum stage, 1.25 

feet at 5 p. m. August 23 (discharge, 795 second-feet).

1921-1925: Maximum stage recorded, 19.5 feet at 10 p. m. April 10,1922 

(discharge, 49,800 second-feet); minimum stage, 1.0 foot at 2 a. m. August 

16, 1921 (discharge, about 670 second-feet; revised).

I)IEGITLATION. No storage reservoirs discharge into Wisconsin River between 

Knowlton and Merrill. See " Regulation " in station description of Wisconsin River at Merrill (p. 73). Between Knowlton and Merrill are four 

dams operated for power.

ACCUBACY, Stage-discharge relation permanent. Rating curve well defined 

between 1,600 and 6,600 second-feet and fairly well defined above 6,600 

second-feet. Operation of water-stage recorder satisfactory during 81 per 

cent of open-water period. Daily discharge ascertained by applying to 

rating table mean daily gage height determined by inspection of recorder 

graph except as indicated in footnote to table of daily discharge. Open 

water records good except for periods when operation of water-stage recorder 

was unsatisfactory, for which they are fair. Winter estimates poor.

WISCONSIN RIVER AT MTTSCODA, WIS.

LOCATION. In sec. 1, T. 8 N., R. 1 W., at highway bridge 1 mile north of Mugcoda, Grant County. Eagle Mill Creek enters from right half a mile below 

station, and Underwood Creek enters from left 4}i miles above.

DRAINAGE ABEA. 10,300 square miles (measured on map issued by Wisconsin 

Geological and Natural History Survey, edition of 1911).

RECORDS AVAILABLE. December 21, 1902, to December 31, 1903; December 1, 

1913, to September 30, 1925. Gage heights November 1,1908, to December 

31,1912, published in United States Weather Bureau Daily River Stages, 

parts 9, 10, and 11.

GAGE. Chain gage fastened to handrail on upstream side of bridge; read by 

Bud Rice. Zero of gage is about 666.2 feet above sea level.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.00 feet at 7 

a. m. June 22 (discharge, 25,100 second-feet); minimum discharge, estimated 

3,200 second-feet January 21 (stage-discharge relation affected by ice).

1903; 1914-1925: Maximum stage recorded, 10.60 feet at 7 a. m. April 16, 

1922 (discharge, 72,100 second-feet); minimum discharge, estimated 1,600 

second-feet December 20, 1921 (stage-discharge relation affected by ice).

According to records of the United States Weather Bureau,5 on June 11 1 

1881, the river reached a stage of 11.1 feet, and during August, 1868, zero 

on gage; discharge not computed owing to changes in channel and datum 

of gage.

REGULATION. Nearest power plant above station is at Prairie du Sac, 40 mile» 

distant; considerable diurnal fluctuation has been observed at gage. Owing 

to regulation by storage in headwaters, the flow at this station is not natural.

ACCURACY. Stage-discharge relation not permanent; affected by shifting control and by ice. Rating curve fairly well defined above and poorly defined 

below 8,000 second-feet. Gage read to hundredths twice daily. Daily dis* 

charge ascertained by applying mean daily gage height to rating table 

except March 12 to September 30, when shifting-control method was used. 

Records poor.

* U. S. Dept. Agr. Daily River Stages, pt. 10, p. 98.

80 SURFACE WATER SUPPLY, 1925, PART V

TOMAHAWK RIVER NEAR BRADLEY, WIS.

LOCATION. In sec. 16, T. 36 N., R. 6 E., 2 miles west of Cassion, 4 miles north 

of Bradley, Oneida County, 4 miles downstream from mouth of Bearskin 

Creek, and 8 miles above mouth of river.

DRAINAGE ABBA. 422 square miles.

RECORDS AVAILABLE. September 18, 1914, to September 30,1925.

GAGE. Slope gage fastened to concrete posts on right bank; read by H. F. 

Hemmings.

DISCHARGE MEASUREMENTS. Made from cable half a mile below gage.

CHANNEL AND CONTROL. Bed at gage and a short distance below, sandy and 

likely to shift. Control is formed by rapids 2,000 feet below gage. Bed 

at cable section heavy gravel. When a head of 15 feet is maintained in 

Rice Lake storage dam, in sees. 4 and 9, T. 35 N., R. 6 E., backwater will 

extend halfway up the rapids and may affect stage-discharge relation 

slightly. Maximum head maintained during year was considerably less 

than 15 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.65 feet 

April 25 and 26 (discharge, 697 second-feet); minimum stage, 1.09 feet 

August 28 (discharge, 148 second-feet).

1914-1925: Maximum stage recorded, 6.9 feet April 24, 1916 (discharge, 

2,200 second-feet); minimum stage, that of August 28 1925. A better 

extension of the low-water part of the rating curve indicates that the minimum discharge for July 1 and August 9, 1921, is 172 second-feet, instead of 

132 second-feet as previously published.

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. Squirrel and Minocqua Reservoirs, 6 having a summer capacity 

of 443,000,000 cubic feet and a winter capacity of 803,000,000 cubic feet, are 

maintained above station for the purpose of regulating the flow of Wisconsin River.

ACCURACY. Stage-discharge relation probably permanent except as affected by 

ice. Rating curve fairly well defined above and extended below 220 secondfeet. Gage read to hundredths once daily. Daily discharge ascertained by 

applying mean daily gage height to rating table except as indicated in footnote to table of daily discharge. Open-water records for medium and high 

stages, fair; low-water and winter records, poor.

BIG EAU PIEINE BITER NEAR STRATFORD, WIS.

LOCATION. In sec. 13, T. 27 N., R. 3 E., at highway bridge at a place locally 

known as Weber farm, 2 miles north of Stratford, Marathon County, and 

1 mile above Chicago & Northwestern Railway bridge. Dill Creek enters 

from right 5 miles above station.

DRAINAGE AREA. 223 square miles (measured on map issued by Wisconsin Geological and Natural History Survey, edition of 1911).

RECORDS AVAILABLE. July 24, 1914, to December 31, 1925, when station was 

discontinued.

GAGE. Vertical staff gage on right bank; read by John Weber.

DISCHARGE MEASUREMENTS. Made by wading or from highway bridge half a 

mile below gage.

CHANNEL AND CONTROL. Bed composed of heavy gravel and rock. Control at 

head of rapids 100 feet below gage. Banks at gage are high but are overflowed at stage of 15 feet.
UPPER MISSISSIPPI BIVEE BASIN 87

EXTRBMBB OP DISCHARGE. Maximum stage recorded during period October 1, 

1924, to December 31, 1925, 6.30 feet at 5 p. m. June 17 (discharge, 2,410 

second-feet); minimum discharge, about 2 second-feet August 22-29.

1914-1925: Maximum stage recorded, 10.9 feet at 4.30 p. m. November 

10, 1919 (discharge, 8,630 second-feet); minimum discharge, that of August 

22-29, 1925. The flood of June, 1914, reached a stage of 20.7 feet as determined by levels run to high-water marks.

ACCURACY. Stage-discharge relation practically permanent except at low stages 

and as affected by ice. Rating curve well defined above and poorly defined 

below 100 second-feet. Gage read to hundredths twice daily. Daily 

discharge obtained by applying mean daily gage height to rating table. 

Records good for high and medium stages and poor for discharge below 100 

second-feet.

The following discharge measurements were made: 

May 5, 1925: Gage height, 1.87 feet; discharge, 26.9 second-feet. 

May 5, 1925: Gage height, 1.87 feet; discharge, 27.1 second-feet. 

June 24, 1925: Gage height, 2.00 feet; discharge, 39.0 second-feet.

KICKAPOO RIVER AT GAYS MILLS, WIS.

LOCATION. In sec. 28, T. 10 N., R. 4 W., at highway bridge immediately below 

Norwood Mill, in Gays Mills, Crawford County, 2 miles below mouth of 

Tainter Creek, and 25 miles above mou^n of river.

DBAINAGE AREA. 629 square miles (measured on map issued by Wisconsin 

Geological and Natural History Survey, edition of 1911).

RECORDS AVAILABLE. December 25, 1913, to September 30, 1925.

GAGE. Chain gage fastened to downstream side of bridge; read by George 

Atwood.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by 

wading.

CHANNEL AND CONTROL. Channel composed of rock covered by a.deposit of 

sand and silt; banks at gage section fairly high and not subject to overflow 

at ordinary high stages. No definite control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 9.02 feet at 

6.20 p. m. June 15 (discharge, 2,480 second-feet); minimum stage, 1.42 

feet at 5.45 p. m. June 8 (discharge, 186 second-feet).

1914-1925: Maximum stage recorded, 15.05 feet March 24,1917 (discharge,, 

about 6,300 second-feet); minimum discharge, about 100 second-feet during 

the later part of January, 1915 (stage-discharge relation affected by ice).

ICE. Stage-discharge relation affected by ice.

REGULATION. Mills at Gays Mills immediately above station, at -Soldiers 

Grove 7 miles upstream, and at several points above Soldiers Grove use comparatively little storage, so that recorded flow past station represents nearly 

the natural flow. During low stages a small diurnal fluctuation is observed 

at gage.

ACCURACY. Stage-discharge relation not permanent; affected by shifting control 

and by ice. Gage read to half-tenths twice daily. Standard rating curve 

poorly defined. Daily discharge ascertained by shifting control method 

except from October 1 to December 10 when mean daily gage height was. 

applied to rating table. Open-water records fair; winter records poor.

ROCK EIVEE AT IYNDON, III.

LOCATION. In sec. 21, T. 20 N., R. 5 E., at highway bridge in Lyndon, Whiteside County, 10 miles above Rock Creek.

DRAINAGE AKEA. 9,010 square miles.

RECOKDS AVAILABLE. November 24, 1914, to September 30, 1925.

GAGE. Chain gage attached to bridge; read by George Cady.

DISCHAKGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTBOL. Bed composed of gravel and boulders; practically 

permanent. Banks wooded.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 17.7 feet at 

5 p. m. February 24 (discharge estimated on account of backwater from 

ice, 39,000 second-feet); minimum stage, 4.00 feet at 5 p. m. September 2 

(discharge, 790 second-feet).

1915-1925: Maximum stage recorded, 19.6 feet February 16, 1918 (discharge not determined because of backwater from ice). Maximum openwater stage recorded, 17.0 feet March 28, 1916 (discharge, 39,SOP secondfeet); minimum stage, 3.72 feet September 27, 1918 (discharge, 655 secondfeet; revision of figure previously published).

DIVERSIONS. Water diverted at Sterling Dam to feed Illinois & Mississippi 

Canal probably averages about 100 second-feet.

REGULATION. Flow past gage is regulated by power plants at and above Sterling. Owing to such regulation mean of two daily readings of gage during 

low stages is probably somewhat less than true mean daily gage height.

ACCURACY. Stage-discharge relation practically permanent except as affected 

by ice. Rating curve well defined. Gage read to hundredths twice daily. 

Diurnal fluctuation at gage rather large during low stages. Daily dischargeascertained by applying mean daily gage height to rating table, except asshown in footnote to table of daily discharge. Open-water records good 

except for extremely low stages, for which they are fair. Winter records 

and records for periods of missing gage height are poor.

The following discharge measurements were made:

April 14, 1925: Gage height, 6.09 feet; discharge, 3,560 second-feet.

September 9, 1925: Gage height, 4.17 feet; discharge, 892 second-feet.

PECATONICA EIVEK AT FREEPORT, HI.

LOCATION. In sec. 32, T. 27 N., R. 8 E., at highway bridge on Hancock Avenue,

Freeport, Stephenson County, 2 miles above mouth of Yellow Creek. 

DRAINAGE AREA. 1,330 square miles. 

RECORDS AVAILABLE. September 11, 1914, to September 30, 1925.
UPPER MISSISSIPPI EIVEE, BASIN 97

GAGE. Chain gage attached to upstream side of bridge; read by W. C. Krueger.

DISCHARGE MEASUREMENTS. Made from upstream side of bridge.

CHANNEL AND CONTROL. Bed composed of sand and silt; somewhat shifting. 

Left bank of medium height and at stages above 17 feet part of flow passes 

over left bank and through East Freeport.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 14.28 feet at 

8 a. m. February 24 (discharge, 4,180 second-feet); minimum stage, 3.40 

feet at 5 p. m. May 25 (discharge, 288 second-feet).

1914-1925: Maximum stage recorded, 19.4 feet March 28, 1916 (discharge, 17,000 second-feet); minimum discharge, 200 second-feet December 

14, 1917.

ICE. Stage-discharge relation affected by ice.

REGULATION. A dam and power plant three-fourths mile upstream regulates 

flow past gage. Only slight diurnal fluctuation is noticeable.

ACCURACY. Stage-discharge relation changed materially during year, probably 

in February, also slightly in June. Rating curves fairly well defined. Gage 

read to hundredths twice daily. Daily discharge ascertained by applying 

mean daily gage height to rating tables except for period of ice effect and 

February 10-20, when shifting-control method was used. Owing to uncertainty of date of shift records October 1 to March 31 may be poor. Records 

April 1 to September 30 are good.

The following discharge measurements were made:

April 15, 1925: Gage height, 4.41 feet; discharge, 453 second-feet.

September 10, 1925: Gage height, 4.00 feet; discharge, 348 second-feet,

SUGAR RIVER NEAR BRODHEAD, WIS.

LOCATION. In sec. 26, T. 2 N., R. 9 E., at highway bridge 2 miles southwest of 

Brodhead, Green County, 2 miles above Jordan Creek, 4 miles below Little 

Jordan Creek, and 12 miles above Illinois State line.

DRAINAGE AREA. 529 square miles (measured on map issued by Wisconsin 

Geological and Natural History Survey, edition of 1911).

RECORDS AVAILABLE. February 7, 1914, to September 30, 1925.

GAGE. Chain gage attached to upstream side of bridge; read by Arthur 

Christenson.

DISCHARGE MEASUREMENTS. Made from upstream side of bridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel; not permanent. 

Control poorly denned. Right bank of medium height and is seldom overflowed; left bank at gage overflowed at stage of 6.8 feet.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 5.40 feet at 

8 a. m. February 10 (discharge, 2,150 second-feet); minimum stage, 0.75 

foot at 5 p. m. September 20 (discharge, 71 second-feet).

1914-1925: Maximum stage recorded, 11.4 feet September 13, 1915 (discharge, about 13,000 second-feet); minimum discharge, about 47 second-feet 

August 26, 1923.

REGULATION. A power plant at Brodhead, 2 miles above station, causes slight 

fluctuation of stage during low water, but the pondage is small, and it is 

believed that the monthly discharge represents the natural flow quite accurately. The difference between morning and evening gage readings is seldom 

more than 0.2 foot. There are two power plants farther upstream, but they 

probably have no effect on the discharge at the gage.

ACCURACY. Stage-discharge relation not permanent; affected by ice and by 

shifting control. Standard rating curve fairly well defined. Gage read to 

quarter-tenths twice daily. Daily discharge ascertained by shifting-control 

method. Records fair.

ICE. Stage-discharge relation affected by ice; observations discontinued during

winter. 

REGULATION. Operation of a power plant at Eldora causes slight diurnal

fluctuation during low water. 

ACCURACY. Stage-discharge relation changed during winter. Rating curves

fairly well defined throughout. Gage read to hundredths twice daily. Daily

discharge ascertained by applying mean daily gage height to rating table.

5.10 feet at 6 p. m. June 21 (discharge, 12,500 second-feet); minimum stage

recorded 0.65 foot September 3 (discharge, 700 second-feet).

1915-1925: Maximum stage recorded, 14.94 feet at 6 p. m. June 8, 1918

(discharge, 63,100 second-feet); minimum discharge recorded, about 400

second-feet December 15-17, 1916.

The flood of June, 1892, was probably much higher than the flood of 1918. 

ICE. Stage-discharge relation affected by ice. 

ACCURACY. Stage-discharge relation fairly permanent. Rating curve fairly well

defined. Gage read to half-tenths once daily. Daily discharge obtained by

applying daily gage height to rating table. Open-water records good; winter

records fair.

The following discharge measurements were made:

April 17, 1925: Gage height, 1.13 feet; discharge, 2,330 second-feet.

September 4, 1925: Gage height, 0.44 foot; discharge, 912 second-feet.

CEDAR RIVER AT CEDAR RAPIDS, IOWA

LOCATION. In sec. 28, T. 83 N., R. 7 W., in central part of Cedar Rapids, Linn 

County, 1,000 feet above Eighth Avenue Bridge and half a mile below dam.

DRAINAGE AREA. 6,640 square miles (measured on base map of Iowa).

RECORDS AVAILABLE. February 14, 1903, to September 30, 1925.

GAGE. Gurley water-stage recorder; inspected by R. S. Toogood. Elevation 

of zero of gage, from Northwestern Railroad levels, 723.03 feet above sea 

level.

DISCHARGE MEASUREMENTS. Made from upstream side of Eighth Avenue 

Bridge.

CHANNEL AND CONTROL. Bed composed of rock and gravel, free from vegetation 

and practically permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.00 feet at 

9 a. m. June 18 (discharge, 12,800 second-feet); minimum stage, 2.44 feet at 

3 p. m. September 12 (discharge, 522 second-feet).

1903-1925: Maximum stage recorded, 17.2 feet April 1, 1912, and March 

26, 1917 (discharge, 54,100 second-feet); minimum discharge, 190 secondfeet September 9, 1921.

Greatest known flood probably occurred in June, 1851, when the maximum 

stage was about 20 feet (discharge, about 65,000 second-feet).

ICE. Stage-dischaige relation affected by ice during extremely cold weather. 

The swift current and proximity to power plant keeps the river open at 

other times.

REGULATION. Power plant half a mile above gage causes marked diurnal fluctuation during all periods of low water.

ACCURACY. Stage-discharge relation practically permanent. Rating curve well 

defined above 800 second-feet. Operation of water-stage recorder satisfactory. Daily discharge ascertained by applying to rating table mean daily 

gage height obtained by inspection of recorder graph except as explained in 

footnote to table of daily discharge. Records good, except for periods when 

stage-discharge relation was affected by ice, for which they are fair.

The following discharge measurement was made: 

May 8, 1925: Gage height, 3,31 feet; discharge, 1,570 second-feet.

114 SURFACE WATEE SUPPLY, 1925, PART V

SKUNK RIVER AT AUGUSTA, IOWA

LOCATION. In sec. 26, T. 69 N., R. 4 W., at highway bridge one-third mile from 

Augusta post office, Des Moines County, and 12.2 miles above mouth.

DRAINAGE AREA. 4,290 square miles (measured on base map of Iowa).

RECORDS AVAILABLE. September 30 to November 15, 1913; May 27, 1915, to 

September 30, 1925.

GAGE. Chain gage attached to downstream handrail of bridge about 95 feet 

from left abutment; read by J. A. Schroder. Zero of gage is at elevation 

528.55 feet, Memphis datum.

DISCHARGE MEASUREMENTS. Made from bridge to which gage is attached or 

by wading.

CHANNEL AND CONTROL. Bed of stream sandy and subject to change. Right 

bank high and will not be overflowed; left bank will be overflowed only at 

extremely high stages. Remains of old milldam 600 feet below gage forms 

control; practically permanent. Riffle at dam causes a drop of abotit 3 feet 

at medium low stages. Backwater from Mississippi River probably will 

not occ r oftener than once in 50 years.

EXTREMES OP DISCHARGE. Maximum discharge recorded during year, estimated 

12,000 second-feet February 24 (stage-discharge relation affected by ice); 

minimum stage recorded, 1.45 feet 9 a. m. September 10 (discharge, 62 

second-feet).

1913; 1915-1925: Maximum stage recorded, 18.0 feet March 28, 1916 (discharge, 30,800 second-feet); minimum stage, 1.29 feet September 8, 1919 

(discharge, 26 second-feet by current-meter measurement).

A stage of about 21 feet (discharge, 45,000 second-feet) was reached on 

or about June 1, 1903.

ICE. Stage-discharge relation affected by ice.

REGULATION. Natural discharge at extremely low stages is affected by operation of power plant at Oakland Mills, 26 miles upstream.

ACCURACY. Stage-discharge relation permanent during the year. Rating curve 

well defined. Gage read to half-tenths once daily. Daily discharge ascertained by applying daily gage height to rating table. Open-water records 

good; winter records fair.

The following discharge measurements were made: 

October 24, 1924: Gage height, 2.38 feet; discharge, 437 second-feet. 

February 5, 1925: Gage height, 3.50 feet (stage-discharge relation affected by 

ice); discharge, 1,240 second-feet.

UPPER MISSISSIPPI RIVER BASIN 119

DBS MOINES RIVER NEAR BOONE, IOWA

LOCATION. In sec. 13, T. 84 N., R. 27 W., at highway bridge near the Boone 

waterworks, 2 miles northwest of Boone, Boone County, and 2 miles above 

Bluff Creek.

DRAINAGE AREA. 5,490 square miles at site used since October 9, 1924 (measured on base maps of Iowa and Minnesota).

HECORDS AVAILABLE. April 1, 1920, to September 30, 1925. At site of old gage 

3^2 miles downstream at Chicago & Northwestern Railway crossing, scattered records of stage have been maintained by the United States Weather 

Bureau from 1905 to 1917.

GAGE. Chain gage attached to upstream side of concrete bridge 200 feet from 

left end. Read by employee of Boone waterworks plant. Gage was moved 

from Centerville bridge in September, 1924, and placed in present location, 

nearly 1 mile farther downstream, on October 9, 1924.

DISCHARGE MEASUREMENTS. Made from bridge to which gage is attached or by 

wading.

 CHANNEL AND CONTROL. Control not well defined. Bed consists of gravel and 

sand and is fairly permanent. An island divides the stream below bridge at 

high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 8.72 feet at 

7 a. m. June 18 (discharge, 4,280 second-feet); minimum stage, 2.48 feet at 

3.30 p. m. September 6 (discharge, 43 second-feet).

1920-1925: Maximum stage recorded, 13.39 feet at 6.30 a. m. July 11, 

1920 (discharge, 16,900 second-feet); minimum discharge that of September 

v6, 1925, as given above.

Highest stage since 1907, 20.54 feet probably occurred on June 6, 1918 

(discharge, about 32,000 second-feet). The above stages refer to datum of 

:gage at site 1 mile upstream.

ICE. Stage-discharge relation affected by ice. Observations discontinued during winter.

REGULATION. The city power plant at Fort Dodge causes some diurnal fluctuation during periods of extremely low water.

ACCURACY. Stage-discharge relation fairly permanent. Rating curve well defined 

between 50 and 11,000 second-feet. Gage read to hundredths twice daily 

and frequently during days of rapidly changing stage. Daily discharge 

ascertained by applying daily gage height to rating table, excpt as indicated 

in footnote to daily-discharge table. Records good.

UPPER MISSISSIPPI EIVEE BASIN 121

DBS MOIWES RIVER AT DBS MOIWES, IOWA

LOCATION. In sec. 2, T. 78 N., R. 24 W., at Walnut Street Bridge in Des Moines, 

Polk County, one-fourth mile below dam of Des Moines Electric Co. and 

one-third mile above mouth of Raccoon River.

DRAINAGE ABE A. 6,180 square miles (measured on base maps of Iowa and 

Minnesota).

RECORDS AVAILABLE. October 1, 1902, to August 3, 1903; October 1, 1914, to 

September 30, 1925, at Walnut Street Bridge. May 27, 1905, to July 20, 

1906, at Interurban Bridge near Highland Park 5 miles upstream. The 

United States Weather Bureau has maintained a station at or near the 

present site since July 1, 1897.

GAGE. Friez water-stage recorder at second pier from east abutment of Walnut Street Bridge; installed January, 1912. Zero of gage is 774.74 feet 

above sea level.

DISCHARGE MEASUREMENTS. Made from one of several bridges near gage.

CHANNEL AND CONTROL. The back fill around the piers of Court Street Bridge, 

one block downstream, forms control for extremely low stages. The remains 

of a low timber dam one-quarter mile below gage form the control during 

medium stages. Both may be drowned out during high stages in Raccoon 

River.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.31 feet at 

9 p.m. June 18 (discharge, 4,920 second-feet); minimum stage, 0.50 foot at 

6 p.m. September 19 (discharge, 95 second-feet).

1915-1925: Maximum discharge, about 41,500 second-feet, June 7, 1918; 

brief periods of zero flow have occurred since construction of dam abov;

ICE. Stage-discharge relation occasionally affected by ice or by ice jams at

bridges below gage. 

REGULATION. Considerable diurnal fluctuation during low water is caused by

operation of power plant at dam one-fourth mile above gage. 

ACCURACY. Stage-discharge relation probably permanent during year. Rating

curve fairly well defined. Operation of water-stage recorder satisfactory.

Mean daily discharge ascertained by applying to rating table mean daily

gage height obtained by inspection of recorder graph. Records fair. 

COOPERATION. Gage-height record furnished by United States Weather Bureau.

The following discharge measurements were made:

June 17, 1925: Gage height, 4.96 feet; discharge, 3,720 second-feet.

September 15, 1925: Gage height, 0.66 foot; discharge, 122 second-feet.

DES MOINES EIVEE AT OTTUMWA, IOWA

LOCATION. At Market Street Bridge, Ottumwa, Wapello County. No large 

tributary within several miles.

DRAINAGE ABBA. 13,200 square miles (measured on base maps of Iowa and 

Minnesota).

RECORDS AVAILABLE. March 28, 1917, to September 30, 1925.

GAGE. Chain gage attached to downstream handrail of bridge.

DISCHARGE MEASUREMENTS. Made from Vine Street Bridge, 1,500 feet below 

gage.

CHANNEL AND CONTROL. Channel fairly permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded, 6.7 feet at 7 a. m. June 

16 (discharge, 13,900 second-feet); minimum discharge probably occurred 

during winter.

1917-1925: Maximum stage recorded, 16.5 feet June 11, 1917 (discharge, 

58,700 second-feet). Minimum discharge estimated less than 350 secondfeet several days during December, 1917.

Maximum discharge since 1850, and probably in the last century, occurred 

on May 31, 1903, and is estimated at 100,000 second-feet.

ICE. Stage-discharge relation affected by ice.

REGULATION. Power plant short distance above gage probably produces some 

diurnal fluctuation at low stages.

ACCURACY. Stage-discharge relation fairly permanent. Rating curve well 

defined. Gage read to tenths once daily. Daily discharge ascertained by 

applying daily gage height to rating table except as explained in footnote 

to table of daily discharge. Open-water records good except for extremely 

low stages for which they are fair. Winter records fair.

COOPERATION. Gage-height record furnished by United States Weather Bureau.

The following discharge measurement was made:

September 24, 1925: Gage height, 1.30 feet; discharge, 458 second-feet.

UPPER MISSISSIPPI BIVEE BASIN 141

DISCHARGE MEASUREMENTS. Made from Cass Street Bridge.

CHANNEL AND CONTROL. Channel excavated in solid rock, with a concrete wall 

on either side; permanent.

EXTREMES OF DISCHARGE. Maximum mean daily discharge during days of record 

for year, estimated 9,850 second-feet October 1; minimum mean daily 

discharge, 6,850 second-feet December 26.

1914-1925: Maximum mean daily discharge during days of record, 18,400 

second-feet March 18, 1919; minimum mean daily discharge, 5,420 secondfeet April 25, 1915.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Water is diverted to Illinois fr Michigan Canal at Dam No. 1 

100 feet above gage.

REGULATION. Flow past gage is largely regulated by operation of power plant 

of Chicago Sanitary District at Lockport, which utilizes flow of Chicago 

Drainage Canal and, to a lesser extent, by operation of Economy Light & 

Power Co.'s plant, 100 feet above gage.

ACCURACY. Stage-discharge relation permanent; not affected by ice. Rating 

curve well defined. Operation of water-stage recorder satisfactory except 

as noted in table of daily discharge. Daily discharge ascertained by use of 

discharge integrator. Records excellent, except for a few short periods 

when recording gage was not operating, for which they are fair.

The following discharge measurements of the Illinois & Michigan Canal were 

made:

June 4, 1925: Discharge, 217 second-feet. 

September 4, 1925: Discharge, 316 second-feet.

ILLINOIS RIVER AT MORRIS, ILL.

LOCATION. In sec. 9, T. 33 N., R. 7 E. third principal meridian, at highway 

bridge in Morris, Grundy County, 7 miles below station formerly maintained 

near Minooka and 10 miles below mouth of Kankakee River.

DRAINAGE AREA. Indeterminate.

RECORDS AVAILABLE. October 1, 1919, to September 30, 1925; January 1, 1903, 

to December 13, 1904, for station near Minooka. Daily readings were 

obtained at present site by United States Engineer Corps December 10, 

1899, to November 30, 1900, and April 20, 1903, to December 11, 1904.

GAGE. Chain gage attached to bridge; read by employee of United States 

Weather Bureau.

DISCHARGE MEASUREMENTS. Made from highway bridge.

CHANNEL AND CONTROL. Bed composed of sand and gravel. Right bank high; 

left bank is overflowed at extremely high stages. Control probably a few 

miles below gage.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 11.7 feet 

March 22 (discharge, 23,600 second-feet); minimum stage, 5.3 feet September 21 (discharge, 7,800 second-feet).

1919-1925: Maximum stage recorded, 20.1 feet April 12, 1922 (discharge, 

60,600 second-feet); minimum stage, 5.2 feet August 9, 1920 (discharge, 

7,600 second-feet).

A discharge of 67,800 second-feet occurred at 8 a. m. March 26, 1904, at 

station near Minooka.

ICE. Stage-discharge relation affected by ice.

REGULATION. Flow at this station includes the flow from Chicago Drainage 

Canal. Operation of power plants at Lockport and Joliet above gage causes 

a considerable diurnal fluctuation at low and medium stages.

ACCURACY. Stage-discharge relation probably permanent during year. Rating 

curve well defined. Gage read to tenths once daily. Daily discharge ascertained by applying daily gage height to rating table. Records good for 

medium and high stages; fair for low stages.

COOPERATION. Gage-height record furnished by United States Weather Bureau.

No discharge measurements were made at this station during the year.

high stages, is composed of mud and may shift. Dam at Copperas Creek 

probably forms control for lowest stages; permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 16.5 feet 

March 26 (discharge, 24,000 second-feet); minimum stage, 9.5 feet September 5, 6, and 9 (discharge, 9,300 second-feet).

1903-1906: Maximum discharge recorded, 57,600 second-feet March 28 

and 29, 1904; minimum discharge recorded, 6,170 second-feet July 18-20, 

1906.

1910-1925: Maximum stage recorded, 24.80 feet April 15-17, 1922 (discharge, 56,700 second-feet); minimum discharge, somewhat less than 7,250 

second-feet occurred during period December 11, 1916, to January 10,1917- 

The highest known flood occurred in 1844, when a stage of about 26.6 

feet on the present gage was reached.

ICE. Stage-discharge relation affected by ice.

REGULATION. Flow at this station includes water diverted from Lake Michigan 

through the Chicago Drainage Canal. No diurnal fluctuation is noticeable.

ACCURACY. Stage-discharge relation practically permanent during year, except 

as slightly affected by ice. Rating curve well defined. Gage read to halftenths once daily. Daily discharge ascertained by applying daily gage 

height to rating table. Open-water records good; records for ice-affected

ILLINOIS RIVER AT BEARDSTOWST.ILL.

LOCATION. In sec. 15, T. 18 N., R. 12 W., at highway bridge on State Street 

Beardstown, Cass County, 9^£ miles below mouth of Sangamon River.

DRAINAGE AREA. 23,445 square miles (since January 17, 1900. the natural runoff has been increased by diversion from Lake Michigan through the Chicago 

Drainage Canal).

RECORDS AVAILABLE. October 1, 1920, to September 30, 1925.

GAGE. Vertical staff gage attached to pile on inside of cribbing about 40 feet 

above center span of bridge.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.
UPPER MISSISSIPPI RIVER BASIN 147

CHANNEL AND CONTROL. Bed composed of sand and mud; except at very high 

stages, control is formed by LaGrange Dam, 11 miles downstream; probably 

permanent. The stage at Beardstown is slightly affected in occasional 

seasons of high water by backwater from Mississippi River, and occasionally 

by backwater from Crooked Creek, which enters 5 miles below Beardstown.

EXTKEMES OF DISCHARGE. Maximum stage recorded during year, 15.4 feet 

March 28 and 29 (discharge, 38,600 second-feet); minimum stage, 7.7 feet 

September 10-12 (discharge, 9,620 second-feet).

1920-1925: Maximum stage recorded, 25.1 feet April 20, 1922 (discharge, 

93,100 second-feet; revision of figure previously published); minimum stage, 

7.7 feet December 19-22, 1922, and September 10-12, 1925 (discharge, 

9,620 second-feet).

Maximum stage since 1844 occurred in 1922. On April 4, 1904, discharge 

was determined by United States Engineer Corps as 115,000 second-feet 

(gage height, 20.0 feet).

ICE. Stage-discharge relation slightly affected by ice in some years.

REGULATION. The flow at this station includes the flow of the Chicago Drainage 

Canal.

ACCURACT. Stage-discharge relation permanent except as affected by ice. Rating curve well defined. Gage read to tenths once daily. Daily discharge 

determined by applying daily gage height to rating table. Records good.

COOPERATION. Gage-height record furnished by United States Weather Bureau.

No discharge measurements were made during the year.

Daily discharge, in second-feet, of Illinois River at Beardstown, III., for the years 

ending September 30, 1922 and 1925

KANKAKEE RIVER AT OUSTER PARK, ILL.

LOCATION. In sec. 19., T. 32 N., R. 10 E., at Wabash Railroad bridge in Custer 

Park, Will County, one-quarter mile above Horse Creek and 18 miles below 

dam and power plant at Kankakee.

DRAINAGE AREA. 4,870 square miles.

RECORDS AVAILABLE. November 6, 1914, to September 30, 1925.

GAGE. Chain gage attached to bridge; read by J. H. Swords to November 30 

and by F. A. Anderson thereafter.

DISCHARGE MEASUREMENTS. Made from upstream side of bridge.

CHANNEL AND CONTROL. Solid rock strewn with boulders and gravel; right half 

of channel deep with fissures in bed; left half shallow; affected by vegetation during summer.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 10.45 feet 

March 21 (discharge, 13,800 second-feet); minimum stage, 5.00 feet at 4 

p. m. September 19 (discharge, 385 second-feet).

1914-1925: Maximum stage recorded, 15.05 feet April 11,1922 (discharge, 

31,200 second-feet); minimum stage, 4.09 feet November 15, 1914 (discharge, 250 second-feet).

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. Operation of power plant at Kankakee causes slight fluctuation 

at gage.

ACCURACY. Stage-discharge relation changed during year by growth of vegetation in channel. Rating curves fairly well defined. Gage read to hundredths 

twice daily. Daily discharge ascertained by applying mean daily gage 

height to rating tables, except for periods October 16-25, May 6-15, and 

June 15 to September 30, when indirect method for shifting control was 

used. Records good except for ice period for which they are poor.

The following discharge measurements were made: 

April 7, 1925: Gage height, 6.55 feet; discharge, 2,820 second-feet. 

August 28, 1925: Gage height, 5.29 feet (stage-discharge relation affected by 

growth of grass in channel); discharge, 494 second-feet.

Sundays during September to March, inclusive, and one day a week during 

remainder of year. Effect of operation of mill on gage height is appreciable 

only at low stages and gage is usually read when mill is not running.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined. 

Gage read to hundredths twice daily. Daily discharge ascertained by 

applying mean daily gage height to rating table except as explained in footnote to table of daily discharge. Records good except for estimated period 

July 11-31, for which they are poor.

28,900 second-feet); minimum stage, 1.35 feet July 31 and August 27-29, 

1914 (discharge, 3.8 second-feet).

High water of September, 1911, reached a height of about 25.8 feet on 

present gage; flood of 1883, when there was backwater from ice, reached a 

stage of about 33.0 feet on the present gage.

ICE. Stage-discharge relation affected by ice.

ACCURACY. Stage-discharge relation changed probably in February. Rating 

curves fairly well defined. Gage read to hundredths once daily. Daily 

discharge ascertained by applying daily gage height to rating table. Records 

good except during period of ice effect, for which they are poor.

The following discharge measurement was made:

December 3, 1924: Gage height, 3.96 feet (stage-discharge relation affected by 

ice); discharge, 169 second-feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 17.15 feet

March 17 (discharge, 3,410 second-feet); minimum discharge, 0.9 foot

December 1 and 2.

1917-1925: Maximum discharge recorded, 11,800 second-feet March 15,

1922; minimum discharge, no flow, August 29 and October 6-23, 1922. 

A stage of about 27.3 feet on present gage is said to have been reached

January 31, 1916 (discharge, 11,300 second-feet). 

ICE. Stage-discharge relation not affected by ice. 

DIVERSIONS. An average of about 0.5 second-foot is used for boiler feed and

other purposes at power plant just above gage. 

ACCURACY. Stage-discharge relation changed probably during March. Hating

curves fairly well defined. Gage read to half-tenths once daily. Daily

discharge ascertained by applying daily gage height to rating tables

Records good for medium and high stages; poor for low stages.

The following discharge measurement was made:

April 24, 1925: Gage height, 6.47 feet; discharge, 99.1 second-feet.

Daily discharge, in second-feet, of South Fork of Sangamon River at power plant
