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, 1926.

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 the execution of the work many private and State organizations 

have cooperated, either by furnishing data or by assisting in collecting data. Acknowledgments for cooperation of the first kind are 

made in connection with the description of each station affected; 

cooperation of the second kind is acknowledged on page 10.

Measurements of stream flow have been made at about 5,250 

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

the Hawaiian Islands. In July, 1926,1,730 gaging stations were being 

maintained by the Geological Survey and the cooperating organiza-
2, SURFACE WATER SUPPLY, 1926, PART V

tions. Many miscellaneous discharge measurements were 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 water-supply papers from time to time.

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 divided 

into two groups (1) those that represent a rate of flow, as secondfeet, gallons per minute, miner's inches, and discharge in secondfeet 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, acre-feet, and millions 

of cubic 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 depth 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 natural section or sections 

of the stream channel below the gage which determines 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, 1926, PART V 3 

EXPLANATION OF DATA

The data presented in this report cover the year beginning October 

1,1925, and ending September 30,1926. At the beginning of January 

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

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

ponds, lakes, and swamps, or 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 hi the ground; therefore the runoff for the year beginning October 1 is practically all derived from 

precipitation within that year.

The base data collected at gaging stations consists of records of 

stage, measurements of discharge, and general information used to

FIGTJKE 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 computed.

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, 1926, 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 the 

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 

are based computations recorded in the remaining columns, which 

are defined on page 2.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

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

permanency 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 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 means for any station may represent with high 

accuracy the qusfatity of water flowing past the gage, but the figures 

showing discharge per square mile and run-off in inches may be 

subject to gross errors caused by the inclusion of large noncontributing districts in the measured drainage area, by lack of information 

concerning water diverted for irrigation or other use, or by inability 

to interpret the effect of artificial regulation of the flow of the river 

above the station. "Second-feet per square mile" and "run-off in 

inches" are therefore not computed if such errors appear probable. 

The computations are also omitted for stations on streams draining 

areas in which the annual rainfall is less than 20 inches. All figures 

representing "second-feet per square mile" and "run-off in inches" 

published in the earlier reports by the Geological Survey 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 tfee 

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, 1926, PART 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 

1926. The data for any particular station will be found in the 

reports covering the years during which the station was maintained. 

For example, data for Machias River at Whitneyville, Maine, 1903 to 

1921, are published in Water-Supply Papers 97, 124, 165, 201, 241, 

261, 281, 301, 321, 351, 381, 401, 431, 451, 471, 501, and 521, which 

contain records for the New England streams from 1903 to 1921. 

Results of miscellaneous measurements are published by drainage,

BOIS DES SIOUX RIVER HEAR TENNE7, MINN.

LOCATION, Near center of sec. 22, T. 130 N., R. 47 W., at Soo Railway bridge 

5 miles west of Tenney, Wilkin County, Minn., and 2 miles east of Fairmount, 

N. Dak.

DRAINAGE ABEA. 1,460 square miles.

RECORDS AVAILABLE. April 1, 1919 to September 30, 1926.

GAGE. Vertical staff gage attached to piling pier of the Soo railway bridge; 

read by Harry Voss.

DISCHARGE MEASUREMENTS. Made from highway bridge, from railway bridge, 

or by wading.

CHANNEL AND CONTROL. Bed composed of silt and fine clay, overgrown with 

weeds, which clog the channel by an amount varying with the season. No 

considerable shifts in channel likely because normal velocities are insufficient 

to erode.

EXTREMES OF DISCHARGE. Maximum discharge recorded during year, 32 secondfeet March 18 and 19; no flow during greater part of year.

1919-1926: Maximum discharge recorded 390 second-feet April 22, 1922; 

no flow during several long periods.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. None.

REGULATION. There are no reservoirs or power plants which affect the flow. 

The station is 15 miles below the outlet of Lake Traverse with no considerable tributaries entering between so that abrupt changes in discharge are 

unlikely. Very extensive ditching and drainage work in the tributary area 

during the past twenty years may affect the distribution of flow.

ACCURACY. Stage-discharge relation during March probably affected by ice and 

by shifting control. No discharge measurements made; 1923 rating used. 

Records poor. Report of no flow during rest of year is reliable.

During the years ending September 30, 1924 and 1925 the observer reported 

no flow during the entire climatic years. The report of no flow was confirmed 

by three visits made by the hydrographer during those years.

RED LAKE RIVER AT THIEF RIVER FALLS, MIHN.

LOCATION. In sec. 33, T. 154 N., R. 43 W., one-third mile below dam at Thief 

River Falls, Pemnington County, and 1 mile below mouth of Thief River.

DRAINAGE AREA. 3,430 square miles.

RECORDS AVAILABLE. July 1, 1909, to September 30, 1918, and March 25, 1920, 

to September 30, 1926.

GAGE. Inclined staff gage on right bank; read by Thomas Hastad.

DISCHARGE MEASUREMENTS. Made from cable near gage.

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

permanent.

EXTREMES OF DISCHARGE. Maximum open-water stage recorded during year, 

8.0 feet June 22 (discharge, 2,550 second-feet); minimum discharge, estimated 19 second-feet March 4 (stage-discharge relation affected by ice).

1909-1918; 1920-1926: Maximum open-water stage recorded, 12.2 feet 

April 19-21, 1916 (discharge, 7,040 second-feet); no flow July 17 and 

August 27, 1911.

ICE. Stage-discharge relation seriously affected by iee.

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

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

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

mill (chiefly during the day) causes fluctuations in stage at the gage.

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

Rating, curve fairly well defined. Gage read to half-tenths orce daily during 

summer ar-d 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 medium and high stages, good; at low 

stages, fair. Winter records poor.

No discharge measurements made at station during year.

BED LAKE RIVER AT CROOKSTOH, MZNff.

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

bridge in Crookston, Polk County, one-fourth 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, 1926.

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

Zero of, gage is 833.54 feet above sea level.

DISCHARGE MEASUREMENTS. Made from highway bridge at gage.

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

control not well defined. One channel at all stages.
HUDSON BAY DRAINAGE BASIJf

EXTEEMES OF DISCHARGE. Maximum stage recorded during year, lfi.3 feet 

March 24 (discharge, 6,500 second-feet); minimum discharge, 92 secondfeet measured by current meter on August 30.

1901-1926: Maximum discharge 14,700 second-feet July 5, 1919; minimum stage, 2.0 feet August 6-8, 1925 (discharge, 5 second-feet). Minimum 

discharge due to regulation.

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. Diurnal fluctuation in stage, particularly at low water, is caused 

by operation of power plant immediately above the station and by another 

plant 8 "miles upstream. Storage at these plants is small, so that mean 

monthly flow should represent nearly the natural flow.

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

winter and by aquatic growth during summer. Standard rating curve well 

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

gage height may be considerably in error on account of regulation. Daily 

discharge ascertained by applying daily gage height to rating table. Shiftingcontrol method applied June 27 to September 30 on account of aquatic 

growth in channel. Records fair except for periods of low water or ice effect, 

for which they are poor.

The following discharge measurements were made: 

October 30, 1925: Gage height, 3.34 feet; discharge, 352 second-feet. 

August 30, 1-926: Gage height, 3.61 feet; discharge, 92 second-feet. 

September 1, 1926: Gage height, 4.28 feet; discharge, 283 second-feet.

Daily discharge, in second-feet, of Red Lake River at Crookston, Minn., for the year 

ending September 30, 1926

KAWISHIWI BIVER REAR WINTON, MERIT.

LOCATION. In lot 3, sec. 20, T. 63 N., 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 ABEA. 1,200 square miles.

28 StJRFACE WATER SUPPLY, 1926, PART V

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

September 30, 1919; and September 1, 1923, to September 30, 1926.

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 OF DISCHARGE. Maximum mean daily discharge recorded during 

year, 3,010 second-feet October 6; minimum mean daily discharge, no flow 

on numerous days during the year.

1905-1907; 1912-1919; and 1923-1926: 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, 1925, and 1926. 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, when 

the records are fair.

COOPERATION. Records furnished by Minnesota Power & Light Co.

UPPER MISSISSIPPI RIVER BASIN

MISSISSIPPI BITER ABOVE SANDY BITER, NEAR 1IBBY, MINK.

LOCATION. In SE. % sec. 2, T. 50 N., R. 24 W., 4 miles north of Libby post 

office, Aitkin County, 4 miles above mouth of Sandy River, the outtet of 

Sandy Lake Reservoir. Libby Creek enters from left just below gage.

DBAINAGE AREA. 4,560 square miles.

RECORDS AVAILABLE. August 1, 1925, to September 30, 1926. From September 

1, 1895, to September 30, 1915, records were obtained by the United States 

Engineer Corps at a station 4 miles downstream, having practically the 

same drainage area.

GAGE. Gurley water-stage recorder on left bank; inspected by G. Buckholts,

DISCHARGE MEASUREMENTS. Made from boat in vicinity of gage.

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

Banks of medium height and will seldom be overflowed.

EXTREMES OF DISCHARGE. Maximum stage recorded during period, 22.40 feet 

October 3 (discharge, 2,320 second-feet); minimum stage, 18.20 feet August 

17 (discharge, 411 second-feet).

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

40 miles above station, but the regulation from this plant is very Blight. 

Three of the system of six reservoirs operated by the United States Government in the interests of navigation discharge into Mississippi River 

above the station. Total capacity of these reservoirs is 82 billion -cubic feet. 

Monthly discharge is affected by regulation, yearly discharge is probably 

nearly natural.

ACCURACY. Stage-discharge relation probably permanent during year. Rating 

curve fairly well defined. Operation of water-stage recorder satisfactory. 

Daily discharge ascertained by applying to rating table mean daily gage 

height obtained by inspection of recorder graph. Records fair.

The following discharge measurements were made:

October 8, 1925: Gage height, 21.61 feet; discharge, 1,960 second-feet.

September 5, 1926: Gage height, 19.25 feet; discharge, 805 second-feet.

miles below mouth of Swan River.

DBAINAGE ABBA. 11,600 square miles.

RECORDS AVAILABLE. March 8, 1924, to September 30, 1926.

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

opening and head is determined for each hour during the day and used to 

compute mean daily discharge through the plant. The waste is computed 

from a calibration of discharge through the Tain tor gates at various openings and added to the discharge through the wheels.

EXTREMES OP DISCHARGE. Maximum mean daily discharge recorded during 

year, 5,910 second-feet March 26; minimum mean daily discharge, 625 

second-feet January 2.

1924-1926: Maximum discharge recorded, 7,640 second-feet August 7, 

1924; minimum discharge, 351 second-feet January 4, 1925.

REGULATION. Considerable diurnal fluctuation is caused by operation of power 

plants. 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.

32 STOFACE WATEB SUPPLY, 1926, PART V

MISSISSIPPI RIVER AT ELK RIVEB, MUTN.

LOCATION. 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.

DBAINAGE ABEA. 14,500 square miles.

RECORDS AVAILABLE. July 22, 1915, to September 30, 1926.

GAGE. Chain gage bolted to downstream handrail of bridge near right bank; 

read by W. H. Ebner.

DISCHABGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTBOL. Bed composed of sand and gravel. Control poorly 

defined. Banks high and not subject to overflow.

EXTBEMES OP DISCHABGE. Maximum stage recorded during year, 6.72 feet at 

7.10 p. m. March 27 (discharge, 13,100 second-feet); minimum discharge, 

estimated 633 second-feet February 10. (Stage-discharge relation affected 

by ice.)

1915-1926: Maximum open-water stage recorded, 10.8 feet April 7, 1916 

(discharge, 27,000 second-feet); minimum discharge, that of February 10, 

1926.

Maximum discharge probably occurred on April 5, 1917, and has been 

estimated at about 34,000 second-feet from records of discharge at Coon 

Rapid* power plant.

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

is eliminated before reaching station. Flow of river is controlled by Government dams on the upper river for the purpose of increasing low-water 

open-season flow in the interests of navigation. Daily and monthly discharge 

somewhat affected by regulation, but yearly discharge represents very nearly 

the natural flow.

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:

August 30, 1926: Gage height, 2.80 feet; discharge, 2,230 second-feet.

Daily discharge, in second-feet, of Mississippi River at Elk River, Minn., for the 

year ending September 30, 1926

DRAINAGE AREA. 35,700 square miles.

RECORDS AVAILABLE. March 22, 1887, to September 30, 1926. Observation of 

stage was 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. Au water-stage recorder installed in a wooden well and shelter attached 

to upstream end of shear fence. Inspected by W. S. Olson.

DISCHARGE MEASUREMENTS. Made from downstream side of Wabasha Street 

Bridge or from Chicago Great Western Railway bridge.

CHANNEL AND CONTROL. Channel fairly permanent. Control not well defined. Dredging work for the improvement of navigation has lowered the 

low-water control about 2 feet in past 20 years.
34 SURFACE WATER SUPPLY, 1926, PART V

EXTBEMES OF DiscHABGE. Maximum stage recorded during year, 5.3 feet at 

1 a. m. March 28 (discharge, 14,500 second-feet); minimum stage, 2.3 

feet at noon November 29 (discharge, 1,730 second-feet).

1887-1926: Maximum stage recorded, 18.0 feet April 6, 1897 (discharge, 

80,800 second-feet); minimum discharge, 1,060 second-feet February 4, 1895. 

Greatest known discharge, 117,000 second-feet July 22, 1867.

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. During low water operation of Ford power plant at the Government high dam, just above mouth of Minnesota River, causes diurnal 

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

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

open-season 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 year except as 

affected by ice. Rating curve fairly well defined. Operation of waterstage recorder satisfactory during open-water periods. Daily discharge 

ascertained by applying to rating table mean daily gage height obtained by 

inspection of recorder graph. Records good.

MINNESOTA RIVER NEAR MONTEVIDEO, MINN.

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, 1926.

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

by Elizabeth Hendricks.

DISCHARGE MEASUREMENTS. Made from highway bridge.

CHANNEL AND CONTROL. Bed composed of heavy gravel and sand; fairly permanent. There is a slight riffle just below gage, but control section is poorly 

defined. Banks subject to overflow at a stage of 14 feet.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 6.50 feet at 

5.30 a. m. March 23 (discharge, 1,130 second-feet); minimum stage, 1.50 

feet July 28, 29, and 31 (discharge, 34 second-feet).

1909-1926: 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; discharge not determined 

during winter.

REGULATION. No regulation on Minnesota River above station. Regulation of 

Chippewa River at plant of Chippewa Milling Co., in Montevideo, causes 

slight fluctuation in stage of Minnesota River at gage.

ACCURACY. Stage-discharge relation probably fairly permanent during year. 

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

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

Records good.

The following discharge measurement was made:

August 28, 1926: Gage height, 3.77 feet; discharge, 380 second-feet.

MINNESOTA RIVER AT MANKATO, BONN.

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.

DBAINAGE ABEA. 14,600 square miles.

RECOBDS AVAILABLE.: March 15, 1922, to September 30, 1926, 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.

GAGE. Au water-stage recorder on left bank at downstream side of bridge; gage 

inspected by J. J. Pihale.

DISCHABGE MEASUREMENTS. Made from highway bridge.
UPPER MISSISSIPPI RIVER BASIN 37

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

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

poorly defined.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 8.8 feet at 

midnight March 22 (discharge, 4,880 second-feet); minimum stage, 3.20 

feet at 6 p. m. November 27 (discharge, 96 second-feet).

1903-1926: 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 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. Stage-discharge relation affected by ice; observations discontinued 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 the flow 

at Mankato station and produces considerable daily fluctuation at gage, 

amounting at times to more than a foot.

ACCURACY. Stage-discharge relation changed probably during ice period. 

Rating curve for 1925, which was assumed to be applicable, used October 1 

to January 11 and is fairly well defined. Curve used March 16 to September 

30 poorly defined. Operation of water-stage recorder satisfactory. Daily 

discharge ascertained by applying to rating table mean daily gage height 

obtained by inspection of recorder graph. Shifting-control method used 

July 1 to September 30. Records poor.

The following discharge measurement was made:

August 27, 1928: Gage height, 3.87 feet; discharge, 578 second-feet.-

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

during summer may cause a small amount of backwater. Left bank high 

and not subject to overflow; right bank of medium height and may be overflowed during extremely high water.

EXTREMES OF DISCHARGE. Maximum open-water stage recorded during year, 

2.2 feet April 17 and 18 (discharge, 2,030 second-feet); minimum discharge, 

estimated 541 second-feet November 26-28 (stage-discharge relation affected 

by ice).

1914-1926: Maximum stage recorded, 6.73 feet at 6.45 a. m. April 22, 

1916 (discharge, 8,480 second-feet); minimum stage, 0.22 foot several times 

during later half of August, 1925 (discharge, 518 second-feet).

ICE. Stage-discharge relation seriously affected by ice.

ACCURACY. Stage-discharge relation permanent during the year except as 

affected by ice. Rating curve fairly well defined. Ga?ge read to quartertenths twice daily. Daily discharge ascertained by applying mean daily 

gage height to rating table except as indicated in footnote to table of daily 

discharge. Records good.

The following discharge measurements were made:

December 23, 1925: Gage height, 1.40 feet; discharge, 630 second-feet (stagedischarge relation affected by ice).

February 9, 1926: Gage height, 2 feet; discharge, 622 second-feet (stagedischarge relation affected by ice).

July 14, 1926: Gage height, 0.75 foot; discharge, 860 second-feet.

ST. CROIX RIVER NEAR BUSH CITY, MINN.

LOCATION. In SW. % sec. 8, T. 37 N., R. 20 W., at Northern Pacific Railway 

bridge, 5 miles east of Rush City, Chicago County, and 10 miles below 

mouth of Snake River.

DBAINAGE AREA. 5,120 square miles.

RECORDS AVAILABLE. April 18, 1923, to September 30, 1926.

GAGE. Chain gage attached to downstream side of railroad bridge neat right 

end; read by Fred Heinrich.

DISCHARGE MEASUREMENTS. Made from upstream side of bridge.

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

Control poorly defined. Aquatic plants cause backwater during summer.

EXTREMES OF DISCHARGE. Maximum open-water stage recorded during year, 

4.5 feet September 20 and 21 (discharge, 5,660 second-feet); minimum 

discharge, estimated 820 second-feet several days during December, 

January, and March (stage-discharge relation affected by ice).

1923-1926: Maximum open-water stage recorded, 6.3 feet May 14 and 15, 

1924 (discharge, 13,700 second-feet); minimum discharge, 820 secondfeet August 26 and 27, 1925. A discharge of 820 second-feet was also 

estimated several times in December, 1925, and January and March, 1926.

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

growth of grass in channel. Rating curve fairly well defined between 

820 and 5,020 second-feet. Gage read to tenths twice daily. Daily 

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

' Shifting-control method used June 18 to September 30. Open-water 

records fair; winter records poor.

COOPERATION. Gage-height record furnished by Northern States Power Co.

The following discharge measurements were made:

February 2,1926: Gage height, 3.57 feet; discharge, 1,090 second-feet (stagedischarge relation affected by ice).

July 13, 1926: Gage height, 2.98 feet; discharge, 1,530 second-feet.

ST. CROIX RIVER NEAR ST. CROIX FAILS, 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.

DRAINAGE AREA. 5,930 square miles.
UPPER MISSISSIPPI RIVER BASIN 43

RECORDS AVAILABLE. January 1, 1910, to September 30, 1926. 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, 6,140 second-feet September 22; minimum mean daily discharge, 499 

second-feet December 13.

1902-1905; 1910-1926: Maximum discharge recorded, 35,800 secondfeet March 26, 1920; minimum discharge recorded, 75 second-feet July 17, 

1910 (caused by regulation).

REGULATION. Low-water flow controlled by operation of gates of power plant 

and by storage and release of water at Never's dam, 10 miles upstream.

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

plant was made by 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, which 

remained in use until December 31, 1925. New calibration curves, based 

on the the test made during June and July, 1925, were prepared, and were 

used for obtaining discharge beginning January 1, 1926. Records good.

COOPERATION. Records furnished by the Northern States Power Co.

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

year ending September SO, 1926

APPLE EIVER NEAR SOMERSET WIS.

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

Power Co., 3% miles below Somerset, St. Croix County, and 2 miles above 

mouth.

DBAINAGE AREA. 550 square miles (measured on map issued by Wisconsin 

Geological and Natural History Survey, edition of 1911).
46 SURFACE WATER SUPPLY, 1926, PART V

RECORDS AVAILABLE. January, 1901, to September 30, 1926.

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

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 aumber 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 so wasted the quantity 

is computed from weir formulas 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 recorded during year,, 

932 second-feet March 25; minimum mean daily discharge, 4Q second-feet 

July 16.

1904-1926: Maximum mean daily discharge recorded, 2,280 second-feetin 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. The pondageof these plants is small, and though daily flow may be controlled to someextent, mean monthly flow probably represents nearly the natural flow.

COOPERATION. Records furnished by Northern States Power Co.

No discharge measurements made at station during year.

channel at all stages. Banks not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 8.50 feei 

September 20-24 (discharge, 4,920 second-feet); minimum stage, 3.5 feet 

April ljO-12 (discharge, 33 second-feet). Both maximum and minimum 

stages are the result of regulation and have no bearing on the natural flow. 

1912-1926: Maximum stage recorded, 9.56 feet April 22, 1916 (discharge, 

6,940 second-feet); minimum stage, 3.25 feet April 17-20 and May 1-5,

Chippewa Eeservoir owned by Northern States Power Co. This reservoir 

is just below the confluence of East and West Forks of Chippewa Eiver 

3 miles above station and has a capacity of 10 billion cubic feet. There is 

also a reservoir 1*6 miles above station that has a capacity of 550 million 

cubic feet.

ICE. Stage-discharge relation seriously affected by ice during year.

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

Eating curve well defined above 200 second-feet and fairly well defined below. 

Gage read to half-tenths twice daily. Daily discharge ascertained by applying mean daily gage height to rating table. Open-water records for medium 

and high stages, excellent; for low stages, fair. Winter records poor.

The following discharge measurement was made:

June 18, 1026: Gage height, 3.63 feet; discharge, 57 second-feet.

third channel nearest east bank has a tendency to fill with sand deposited 

by Thornapple River. Flow except during extremely high stages is confined 

within the banks.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 11.9 feet at 

2.35 p. m. September 19 (discharge, 12,700 second-feet); minimum stage 

1.15 feet August 1-3 (discharge, 275 second-feet). The minimum discharge 

was caused by regulation.

ACCURACY. Stage-discharge relation shifted slightly during the year; affected 

by ice. Rating curve fairly well denned above 300 second-feet. Gage 

read to half-tenths once daily. Daily discharge ascertained by 'applying 

daily gage height to rating table except from April 11 to June 30, when 

shifting-control method was used. Records fair.

CHIPPEWA RIVER AT CHIPPEWA FALLS, WIS.

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

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

DRAINAGE AREA. 5,600 square miles.

HECOHDS AVAILABLE. June 22, 1888, to September 30, 1926.

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, 12.55 feet at 

10 a. m. September 20 (discharge, 46,400 second-feet); minimum stage, 

 0.92 foot at 7 a. m. March 15 (discharge, about 126 second-feet). Maximum and minimum stages taken from recorder graph.

1888-1926: 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
tTPPER MISSISSIPPI RIVER BASIN 51

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.

ACCTJKACY. Stage-discharge relation practically permanent; not affected by ice 

during year. Rating curve well defined above 2,000 second-feet and fairly 

well defined below. Operation of water-stage recorder satisfactory except 

as indicated in footnote to table of daily discharge. Daily discharge 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 making corrections so as to approximate the results obtained by 

averaging the hourly discharge. Records fair.

The following discharge measurement was made:

July 12, 1926: Gage height, 1.99 feet; discharge, 5,240 second-feet.

Daily discharge, in second-feet, of Chippewa River at Chippewa Falls, Wis., for the 

year ending September SO, 19%6

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.

DKAINAGE ABBA. 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, 1926.

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

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 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, 3.46 feet 

July 10 and 11 (discharge, 1,120 second-feet); minimum discharge, estimated 

150 second-feet March 25 (stage-discharge relation affected by ice).

1914-1926: Maximum stage recorded, 9.0 feet April 22 and 23, 1916 

(discharge, 5,430 second-feet); minimum stage, 0.25 foot September 18 and 

19, 1925 (discharge, 91 second-feet).

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. The Flambeau Reservoir dam situated on south line of sec. 34, 

T. 42 N., R. 2 E., 9 miles above gage, and having an estimated capacity of 

6,000,000,000 cubic feet was put into operation on March 16, 1926. This 

reservoir is owned by Chippewa & Flambeau Improvement Co. and operated by it in the interests of power development. The Flambeau Reservoir 

together with other smaller reservoirs having an aggregate'capacity of 1.16 

billion cubic feet regulate the entire flow at the station.

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. Openwater records good; winter records fair.

54 SURFACE WATER SUPPLY, 1926, PART V

FLAMBEAU EIVEE NEAB 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 Lady smith, 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, 1926. 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.

DETERMINATION OP DISCHARGE. Daily discharge computed from, hourly determinations of flow through each turbine based on kilowatt output, and theflow through waste gates and over spillway as computed* from hourly determinations based on theoretical formulas.

EXTREMES OP DISCHARGE. Maximum mean daily discharge recorded during' 

year, 8,860 second-feet September 19; minimum mean daily discharge, 323S 

second-feet November 23.

1903-1906; 1914-1926: Maximum discharge recorded, 19,500 second-feet 

April 11, 1922; minimum discharge, 176 second-feet August 30, 1925. Theminimum discharge was caused by regulation.

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

station is located. The Chippewa & Flambeau Improvement Co. operate 

storage reservoirs on the headwaters having an effective capacity of 7.15» 

billion cubic feet. See "Regulation" in station description for Flambeau' 

River near Butternut. 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 i* based 

on a series of discharge measurements made by engineers of the Geological 

Survey in October, 1925. The computation of discharge through the turbinesis good. Computation of waste is poor. Records good except at high stages, 

for which they are fair.

COOPERATION. Power-house data furnished by Lake Superior District Power Co.

Daily discharge, in second-feet, of Flambeau River near La<$ysmithr Wis., for the 

year ending September 30, 1926

Geological and Natural History Survey, edition of 1911).

RECORDS AVAILABLE. July 16, 1914, to September 30, 1926, when station was 

discontinued.

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 the control. Banks high and not subject to overflow.

EXTREMES OP DISCHARGE. Maximum open-water stage recorded during year, 

8.0 feet at 8 a. m. August 22 (discharge, 4,560 second-feet; minimum discharge, estimated 40 second-feet January 27-30 (stage-discharge relation 

affected by ice).

1914-1926: 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.

ICE. Stage-discharge relation seriously affected by ice.

ACCURACY. Stage-discharge relation not permanent. Affected by ice and by 

shifting control. Rating curve fairly well defined. Gage read to quartertenths once daily. Daily discharge ascertained by applying daily gage 

height to rating table. Records at medium and high stages fair; low-water 

and winter records poor.

The following discharge measurements were made:

January 1, 1926: Gage height, 1.05 feet; discharge, 79 second-feet (stagedischarge relation affected by ice).

CHANNEL AND CONTROL. Bed at gage composed of heavy gravel. Left ( bank 

high and not subject to overflow; right bank of medium height and will be 

overflowed at flood stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.25 feet at 

midnight March 25 (discharge, 11,000 second-feet); minimum stage, 0.93 

foot May 9 (disch^ajrge, 88 second-feet).

1907-8, 1913-1923, 1925-1926: Maximum discharge, 14,000 second-feet 

March 26,1920; minimum stage, that of May 9,1926. Minimum discharge 

is due to regulation and does not represent the natural flow.
UPPER MISSISSIPPI RIVER BASIN

REGULATION. Considerable diurnal fluctuation at gage is caused by operation of 

power plants of Northern States Power Co. at Menomonie and Cedar Falls. 

(See also "Regulation" in station description for Red Cedar River at Colfax, 

Wis.)

ICE. Stage-discharge relation not affected by ice.

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

defined between 900 and 8,000 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. Records good.

62 SURFACE WATER SUPPLY, 1926, PART V

BLACK RIVER AT NEULSVIIIE, 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, enters l}{ 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, 1926.

GAGE. Chain gage on downstream side of bridge; read by A. Bissell.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by

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

head at rapids, a few hundred feet below gage. Banks high and rocky; 

water will not overflow banks at gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during period October 1, 

1925, to June 15, 1926, 12.0 feet at 7.30 a. m. April 11 (discharge, 10,400 

second-feet); minimum discharge, estimated 30 second-feet January 14 

(stage-dischaige relation affected by ice).

1905-1909; 1913-1926: Maximum stage recorded, 19.8 feet June 6, 1905 

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

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.

REGULATION. Several dams on Black River and its 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.

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

Rating curve well defined between 28 and 14,700 second-feet. Gage read 

to quarter-tenths twice daily. Daily discharge for open-water periods 

ascertained by applying mean daily gage height to rating table. Openwater records good except for estimated period June 16 to September 30, for 

which they are poor. Winter records poor.

The following discharge measurements were made:

January 1, 1926: Gage height, 3.48 feet; discharge, 42 second-feet (stage-discharge relation affected by ice).

February 8, 1926: Gage height, 4.22 feet; discharge, 57 second-feet (stage-discharge relation affected by ice).

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

is a rock riffle with a fall of 6 inches, which is apparently drowned out at a 

stage of about 2.2 feet as shown by 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, 5.85 feet at 

7 a. m. August 22 (discharge, 1,840 second-feet); minimum discharge, 

estimated 110 second-feet December 20 and January 24 (stage-discharge 

relation affected by ice).

1913-1926: Maximum stage recorded, 8.45 feet March 16, 1919 (discharge, 

-afoout 3,620 second-feet). Minimum discharge, estimated 90 second-feet 

January 6, 1924 (stage-discharge relation affected 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 the operation of power plants; especially at 

Neshonoc Dam, a few miles above station.

ACCURACY. Stage-discharge relation slightly shifting; affected by ice. Rating 

curve fairly well defined above 180 second-feet. Gage read to hundredths 

twice daily. Daily discharge for open-water periods ascertained by applying 

mean daily gage height to rating table. Open-water records fair; winter 

records poor.

The following discharge measurements were made:

January 2, 1926: Gage height, 2.46 feet; discharge, 197 second-feet (stagedischarge relation affected by ice).

July 9, 1926: Gage height, 1.40 feet; discharge, 198 second-feet.

Daily discharge, in second-feet, of La Crosse River near West Salem, Wis., for the

UPPER MISSISSIPPI RIVER BASIN

WISCONSIN RIVEK AT WHIRLPOOL RAPIDS, NEAR RHE8TELAKDBR, WE!.

LOCATION. 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.

DRAINAGE AREA. 1,160 square miles (measured on map issued by Wisconsin 

Geological and Natural History Survey, edition of 1911).

RECORDS AVAILABLE. September 15, 1915, to September 30, 1926, and December 1, 1905, to September 30, 1915, records were collected at a station 3 miles 

upstream.

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

Clarence Jewell.

DISCHARGE MASTTREMENTS. Made from cable 150 feet above gage.

CHANNEL 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.

EXTREMES OP DISCHARGE. Maximum discharge records during year, 4,490 

second-feet April 25; minimum discharge, 368 second-feet October 31.

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.

1915-1926: 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. Flow is regulated by 14 reservoirs 2 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 the flow at the station is not natural; -

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

Rating curve fairly well defined. Operation of water-stage recorder satisfactory during only 47 per cent of the year. Daily discharge for open-water 

periods when gage-height records are available ascertained by applying to 

rating table mean daily gage height determined by inspection of recorder 

graph; for remainder of year as explained in footnote to daily-discharge 

table. Records for periods when water-stage recorder was in operation 

are good; records for estimated periods are poor.

The following discharge measurement was made:

June 17, 1926: Gage height, 2.53 feet; discharge, 1,290 second-feet.

Daily discharge, in second-feet, of Wisconsin River at Whirlpool Rapids, near 

Rhinelander, Wis., for the year ending September SO, 1926

WISCONSIN BITES AT MERRILL, WIS.

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,

DKAINAQE AKEA. 2,630 square miles (measured on Wisconsin Geological and 

Natural History Survey map, edition of 1911).

RECORDS AVAILABLE. November 16, 1902, to September 30, 1926.

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.
EXTBBMES OF DiscHAEGE. Maximum stage recorded during year, 10,86 feet at 

6 a. m. August 21 (discharge, 17,400 second-feet); minimum discharge, 

estimated 420 second-feet at 6 a. m. February 8 (stage-discharge relation 

affected by ice).

1902-1926: 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,3 which are operated 

by 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 sis affected 

by ice. Rating curve well defined. Operation of water-stage recorder 

satisfactory. Daily discharge for open-water periods ascertained by applying to rating table mean daily gage height obtained from recorder graph 

by inspection. Open-water records good; winter records fair.

The following discharge measurements were made:

January 22, 1926: Gage height, 4.34 feet; discharge, 1,040 second-feet (stagedischarge relation affected by ice).

February 11, 1926: Gage height, 4.38 feet; discharge, 1,230 second-feet (stagedischarge relation affected by ice).

June 16, 1926: Gage height, 4.65 feet; discharge, 1,530 second-feet.

Daily discharge, in second-feet, of Wisconsin River at Merrill, Wis., for the year 

ending September 30,

WISCONSIN RIVER AT KNOWLTON, WIS.

LOCATION. In N. % sec. 29, T. 26 N., R. 7 E., 50 feet below left end of combination railroad-highway bridge of Chicago, Milwaukee & St. Paul Railway 

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

miles below mouth of Big Eau Pleine River.

DRAINAGE AREA. 1,360 square miles (measured on map issued by Wisconsin 

Geological and Natural History Survey, edition of 1911).

RECORDS AVAILABLE. July 13, 1921, to September 30, 1926. 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.

DISCHARGE MEASUREMENTS. Made from boat, by wading, or from bridge at 

very high stages.

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

well defined; there is, however, a decided contraction of the 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, 18.6 feet at 

7 p. m. August 22 (discharge, 46,600 second-feet); minimum stage, 1.8 feet 

at 2 p. m. November 1 (discharge, 1,080 second-feet).

1921-1926: 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 

15, 1921 (discharge, about 670 second-feet).

REGULATION. No storage reservoirs discharge into Wisconsin River between 

Knowlton and Merrill. See "Regulation" in station description of Wisconsin River at Merrill (p. 69). Between Knowlton and Merrill are four 

dams operated for power.

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

above 1,600 second-feet and extended below. Operation of water-stage 

recorder satisfactory during the year. Daily discharge for open-water 

periods ascertained by applying to rating table mean daily gage height 

obtained from recorder graph by inspection. Open-water records good;, 

winter records poor.

The following discharge measurement was made:

September 16, 1926: Gage height, 9.15 feet; discharge, 17,100 second-feet.

LOCATION. In sec. 15, T. 21 N., R. 5 E., \% miles below Nekoosa, Wood County. 

Tenmile Creek enters 4 miles below station.

DRAINAGE AREA. 5,500 square miles (measured on map issued by Wisconsin 

Geological and Natural History Survey, edition of 1911).

RECORDS AVAILABLE. May 21, 1914, to September 30, 1926.

GAGE. Gurley water-stage recorder on right bank; inspected by Henry Mans.

DISCHARGE MEASUREMENTS. Made from cable just above gage.

CHANNEL AND CONTROL. Bed composed of gravel; clean, nearly permanent. 

Banks high and are rarely overflowed.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 15.08 feet at 

noon August 23 (discharge, 52,700 second-feet); minimum discharge, estimated 665 second-feet February 14 (stage-discharge relation affected by ice). 

1914-1926: Maximum stage recorded, 16.1 feet at 1 a. m. April 12, 1922 

(discharge, 61,000 second-feet); minimum discharge, estimated 400 secondfeet at 6 p. m. January 13, 1924 (stage-discharge relation affected by ice). 

Minimum flow is due to regulation.

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. No storage reservoirs discharge into Wisconsin River between 

Nekoosa and Merrill. See "Regulation" in station description of Wisconsin River at Merrill (p. 69). Between Nekoosa and Merrill are 12 dams 

operated for power.

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

Rating curve well defined. Operation of water-stage recorder satisfactory 

during the year. Daily discharge for open-water periods ascertained by 

applying to rating table mean daily gage height determined by inspection of 

recorder graph. Open-water records good; winter records fair.

WISCONSIN BIVEB AT MUSCODA, WIS.

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

station and Underwood Creek from left 4^ miles above.

DRAINAGE AREA. 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 4, 

1913, to September 30, 1926. Gage heights November 1, 1908, to December 31, 1912, published in United States Weather Bureau bulletin, "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 approximately 666.2 feet above sea level.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 8.28 feet at 

7 a. m. August 29 (discharge, 43,800 second-feet) j minimum discharge, estimated 3,130 second-feet March 8 (stage-discharge relation affected by ice). 

1903; 1914-1926: 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 United States Weather Bureau 4 on June 11, 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.

< Daily river stages, Pt. 10, p. 98, TJ. S. Dept. Agr.
74 SURFAC^

REGULATION. Considerable diurnal fluctuation has been observed at gage owing 

to operation of power plant at Prairie du Sac, 40 miles upstream. Owing 

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

natural.

ACCUBACY. Stage-discharge relation not permanent; affected by shifting control and by ice. Rating curve fairly well defined above 8,000 seeond-feet 

and poorly defined below. Gage read to hundredths twice daily. Daily discharge for open-water periods ascertained by applying mean daily gage 

height to rating table. Records poor.

The following discharge measurements were made:

January 14, 1926: Gage height, 2.38 feet; discharge, 4,090 second-feet (stagedischarge relation affected by ice).

May 21, 1926: Gage height, 2.86 feet; discharge, 9,540 second-feet. 

July 7, 1926: Gage height, 1.92 feet; discharge, 7,610 second-feet.

Daily discharge, in second-feet, of Wisconsin River at Muscoda, Wis., for the year 

ending September 30, 1926

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 AREA. 422 square miles.

RECORDS AVAILABLE. September 18, 1914, to September 30, 1926.

GAGE. A Stevens continuous water-stage recorder was installed October 6, 

1925, on right bank 8 feet downstream from slope gage which it replaces.

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.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.82 feet 

April 18 (discharge, 1,120 second-feet); minimum stage, 1.45 feet November 23 (discharge, 192 second-feet).

1914-1926: Maximum stage recorded, 6.9 feet April 24, 1916 (discharge, 

2,200 second-feet); minimum stage recorded, 1.09 feet August 28, 1925 

(discharge, 148 second-feet).

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. Squirrel and Minocqua Reservoirs,5 having a summer capacity 

of 443 million cubic feet and a winter capacity of 803 million 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 220 second-feet and extended 

below. Operation of water-stage recorder satisfactory October 7-20 and 

October 24 to July 27. Daily discharge for open-water periods ascertained 

by applying to rating table mean daily gage height obtained by inspection 

of recorder graph. Open-water records fair, except for estimated period 

July 28 to September 30, for which they are poor. Winter records poor.

The following discharge measurements were made: 

October 9, 1925: Gage height, 1.95 feet; discharge, 252 second-feet. 

January 23, 1926: Gage height, 2.46 feet; discharge,. %1& seeontisfeet (stagedischarge relation affected by ice). 

July 23, 1926: Gage height, 1.80 feet; discharge, 236 second-feet.

KICKAPOO RIVER AT GAYS MH1S, WIS.

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

dam and power plant of Interstate Power Co., in Gays Mills, Crawford 

County, 2 miles below mouth of Tainter Creek, and 25 miles above mouth 

of river.

DRAINAGE 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, 1926.

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

Atwood, Wylanta Haggerty, and J. M. Haggerty.

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 fairly high and not subject to overflow at ordinary 

high stages. No definite control.

EXTREMES OF DISCHARGES. Maximum stage recorded during year, 8.9 feet at 

6 a. m. August 24 (discharge, 2,100 second-feet); minimum discharge, 

estimated 195 second-feet several times during January and February 

(stage-discharge relation affected by ice).

1914-1926: 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 the 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 natural flow. During low stages a small diurnal fluctuation is 

observed at gage.
ACCTTBACY. Stage-discharge relation not permanent; affected by shifting control 

and by ice. Standard rating curve poorly defined. Gage read to hundredths 

once daily. Daily discharge ascertained by shifting-control method October 

1 to July 8, except during ice-affected periods. Rating applied directly 

July 9-31. For remainder of year discharge was obtained as explained in 

footnote to daily-discharge table. Records poor.

The following discharge measurements were made:

January 15, 1926: Gage height, 2.86 feet; discharge, >244 second-feet (stagedischarge relation affected by ice).

May 21, 192*: Gage height, 2.36 feet; discharge, 308 second-feet. 

July 8, 3926: Gage height. 1.85 feet: discharge. 256 second-feet.

Daily discharge, in second-feet, of Kickapoo River at Gays Mills, Wis., for the year 

ending September 30, 1926

NOTE. Stage-discharge relation affected by ice Dec. 19-23 and Dec. 26 to Feb. 15. Daily discharge 

based on gage heights corrected for effect of ice by means of one discharge measurement, observer's notes, 

and weather records. During August and September the channel was obstructed by piling and forms in 

connection with the construction of a new bridge immediately below the gage, and an estimated correction 

of 15 per cent has been applied to the discharge as taken from the rating table.

BOCK RIVER AT ITS DON, ILL.

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

DRAINAGE AREA. 9,010 square miles.

RECORDS AVAILABLE. November 24, 1914, to September 30, 1926.

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

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

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

permanent. Banks wooded.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 13.9 feet at 

7.30 a. m. February 27 (discharge, 26,600 second-feet); minimum stage, 4.41 

feet at 5 p. m. October 7 (discharge, 1,100 secoDd-feet).

1915-1926: 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, 39,500 secondfeet) ; minimum stage, 3.72 feet September 27, 1918 (discharge, 655 secondfeet; revised).

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

Canal probably averages about 100 second-feet.

HEGULATION. Flow past gage is regulated by power plants at Sterling and 

above. Mean of two daily readings of gage during low stage is probably 

somewhat less than true mean daily gage height due to such regulation.

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

good during open-water periods; poor for period of ice effect.

The following discharge measurement was made: ^ 

June 9, 1926: Gage height, 5.20 feet; discharge, 2,180 second-feet.

UPPER MISSISSIPPI RIVER BASIN 93

SUGAR RIVER NEAR BEODHEAD, 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, 1926.

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, 5.3 feet at 

6 p. m. March 20 (discharge, 2,140 second-feet); minimum stage, 0.62 foot 

at 6 p. m. August 27 (discharge, 65 second-feet).

1914-1926: Maximum stage recorded, 11.4 feet September 13, 1915 

(discharge, about 13,000 second-feet); minimum discharge, about 47 secondfeet 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 ia 

believed that the monthly discharge represents the natural flow quite aeetrrately. The difference between morning and evening gage readings IB 

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 practically permanent during year. Rating curve well defined. Gage lead to quarter-tenths twice daily. Daily 

discharge for open-water periods ascertained by applying mean daily gage 

height to rating table. Records fair.

The following discharge measurements were made:

January 19, 1926: Gage height,. 2.07 feet; discharge, 198 second-feet (stagedischarge! relation affected by ice).

May 8, 1926: Gage height, 1.63 feet; discharge, 270 second-feet. 

September 11, 1926: Gage height, 1.41 feet; discharge, 226 second-feet.

Daily discharge, in second-feet, of Sugar River near Brodhead, Wis., for the year 

ending September SO, 1986

Right bank high and will not be overflowed; levee along left bank, which

broke during the flood of June, 1918. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 11.8 feet at

noon September 25 (discharge, 43,500 second-feet); minimum stage recorded,

 0.20 foot July 25-28 (discharge, 1,090 second-feet). 

1915-1926: Maximum stage recorded, 14.94 feet at 6 p. m. June 8, 1918

(discharge, 63,100 second-feet); minimum discharge, 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 probably fairly permanent during the year.

Rating curve fairly well defined. Gage read to half-tenths once daily.

Daily discharge for open-water periods obtained by applying daily gage height

to rating table. Records poor.

The following discharge measurement was made:

August 28, 1926: Gage height, 1.31 feet; discharge, 2,980 second-feet.

CEDAR RIVER AT CEDAR RAPIDS, IOWA

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

gf^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, 1926. 

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 OP DISCHARGE. Maximum stage recorded during year, 6.7 feet at

4.15 a. m. September 21 (discharge, 11,500 second-feet); minimum stage,

2.48 feet at 3 p. m. January 16 (discharge, 514 second-feet)

1903-1926: Maximum stage recorded, 17.2 feet April 1, 1912, and March

26, 1917 (discharge, 54,100 second-feet); minimum discharge, 190 second-feet

September 9, 1921.

Greatest known flood pr®bafoly occurred in June, 1851, when the maximum

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

ICE. Stage-discharge 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 fairly

satisfactory. Daily discharge for open-water periods ascertained by

applying to rating table mean daily gage height obtained by inspection of

recorder graph. Records good, except at extremely low stages and for

periods when stage-discharge relation was affected by ice, for which they are

fair.

The following discharge measurements were made:

May 4, 1926: Gage height, 3,38 feet; discharge, 1,620 second-feet.

July 29, 1926: Gage height, 2.81 feet; discharge, 890 second-feet.

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, 1926.

GAGE. Chain gage attached to downstream handrail of bridge 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 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 at low and medium stages; practically permanent. Riffle at dam 

causes a drop of about 3 feet at medium low stages. Backwater from Mississippi River probably will not occur oftener than once in 50 years.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 20.4 feet 

September 16 (discharge, 32,000 second-feet from discharge measurement); 

minimum stage, 1.7 feet at 7 a. m. June 10 (discharge, 137 second-feet).

1913; 1915-1926: Maximum stage recorded, that of September 16, as 

given above; minimum stage recorded, 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.

REGULATION. Natural discharge at extremely low stages is occasionally affected 

by operation of power plant at Oakland Mills, 26 miles upstream.

ACCURACY. Stage-discharge relation probably permanent during the year; 

affected by ice. Rating curve well defined. Gage read to half-tenths once 

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

gage height to rating table. Records fair.

The following discharge measurements were made: 

August 27, 1926: Gage height, 3.14 feet; discharge, 1,230 second-feet. 

September 9, 1926: Gage height, 17.88 feet; discharge, 22,500 second-feet. ' 

September 16,1926: 6 Gage height, 20.42 feet; discharge, 32,000 second-feet.

DES MOINES RIVER AT DES MOINES, 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 AREA. 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, 1926, at Walnut Street Bridge. May 27, 1905, to July 20, 

1906, at Interurban Bridge near Highland Park 5. miles upstream. United 

States Weather Bureau has maintained a station at or near present site 

since July 1, 1897.

GAGE. Friez water-stage recorder at second pier from east abutment of Walnut 

Street Bridge; installed January, 1912.

DISCHARGE MEASUREMENTS. Made from one of several bridges near gage.

CHANNEL AND CONTROL. A low timber dam constructed September, 1913, onefourth mile below gage, was partly destroyed in 1915 but still forms control 

at medium stages. Back fill around piers of Court Street Bridge, one block 

downstream, forms control at extremely low stages. Both may be drowned 

out depending on stage in Raccoon River. A new mouth to this river, 

dredged farther downstream in 1914, has somewhat relieved backwater 

conditions at gage.
UPPER MISSISSIPPI RIVER BASIN 115

EXTREMES OP DISCHARGE. Maximum mean daily discharge during year, 12,000 

second-feet, September 20; minimum stage, 0.25 foot at 8 a. m. July 27 

(discharge, 65 second-feet).

1915-1926: Maximum discharge, about 41,500 second-feet, June 7, 1918; 

brief periods of zero flow have occurred since construction of dam above

ICE. Stage-discharge relation not affected by ice since construction of dam 

above gage. Numerous bridges below gage occasionally cause ice jams for 

short periods.

REGULATION. Considerable diurnal fluctuations during low water is caused by 

operation of power plant above. Dam is practically drowned out at stage 

of 22 feet.

ACCURACY. Stage-discharge relation practically permanent except for periods 

of ice effect or backwater from Raccoon River. Rating curve well defined 

between 100 and 20,000 second-feet. Operation of water-stage recorder 

satisfactory. Mean daily gage height obtained by inspection of recorder 

graph. Daily discharge obtained by applying mean daily gage height torating table except as explained in footnote to table of daily discharge. 

Records good except for estimated periods, for which they are fair.

COOPERATION. Gage-height record furnished by United States Weather Bureau.

The following discharge measurement was made:

April 22, 1926: Gage height, 1.65 feet; discharge, 446 second-feet.

Daily discharge, in second-feet, of Des Moines River at Des Moines, Iowa, for the

(discharge, 35,300 second-feet); minimum stage, 1.2 feet Deeemfoer 7 and 

July 21 (discharge, 405 second-feet).

1917-1926: Maximum stage recorded, 16.5 feet June 11, 1917 (discharge, 58,700 second-feet); minimum discharge estimated less than 3501 

second-feet 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.

KEGULATION. Power plant located short distance above gage probably causessome diurnal fluctuation at low stages.

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

Gage, read to tenths once daily. Daily discharge for open-water periods 

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

records good; winter records fair.

DES MOIKES RIVER AT KEOSAUQUA, IOWA

LOCATION. In sec. 36, T. 69 N., R. 10 W., at county bridge in Keosauqua, Van

Buren County, one-fourth mile above old dam site and Government locks.

No important tributary enters Des Moines River for several miles up or

down stream.

DRAINAGE AREA. 13,900 square miles (measured on base map of Iowa). 

RECORDS AVAILABLE. May 29, 1903, to July 21, 1906; April 5 to December 31,

1910; August 3, 1911, to September 30, 1926. 

GAGE. Chain gage attached to upstream handrail of bridge; read by Frank

Schreckengast.

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

CHANNEL AND CONTROL. Channel shifts considerably at flood stages. Control

is a gravel riffle one-fourth mile below gage. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 11.55 feet at

7 a. m. September 15 (discharge, 34,800 second-feet); minimum stage, 0.10

foot several days in July and August (discharge, 570 second-feet).

1903-1906, 1910-1926: Maximum stage recorded, 27.85 feet June 1, 1903

(discharge, about 97,000 second-feet); minimum discharge, 160 second-feet

August 28 to September 6, 1911.

Flood of June 1, 1851, reached a stage of about 24 feet (discharge, about

80,000 second-feet).

ICE. Stage-discharge relation seriously affected by ice. 

ACCURACY. Stage-discharge relation for low stage changed, probably when

heavy ice went out in January. Rating curves fairly well defined above

and extended below 1,000 second-feet. Gage read to half-tenths once daily.

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

height to rating table. Records fair, except at low stages, for which they

are poor.

The following discharge measurements were made: 

August 23, 1926: Gage height, 0.70 foot; discharge, 1,440 second-feet. 

August 26, 1926: Gage height, 0.90 foot; discharge, 1,820 second-feet. 

September 16, 1926: Gage height, 9.58 feet; discharge, 26,400 second-feet.

RACCOON EIVER AT VAN METER, IOWA

LOCATION. In SW. # sec. 22, T. 78 N., R. 27 W., at highway bridge one-third 

mile from railroad station, Van Meter, Dallas County, 1 mile below junction 

of North and South Raccoon Rivers, and 30 miles above junction of Raccoon 

and Des Moines Rivers.
UPPER MISSISSIPPI RIVER BASIN 121

DRAINAGE AREA. 3,410 square miles (measured on base map of Iowa).

RECORDS AVAILABLE. April 25, 1915, to September 30, 1926.

GAGE. Gurley 7-day water-stage recorder installed May 31, 1923; inspected by 

Cal Smith.

DISCHARGE MEASUBBMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel; subject to changeRiver divided into two channels at low-and medium stages by an islandRight bank high; left bank subject to overflow at a stage of 13 feet. Atextremely high stage this overflow extends for several hundred feet beyondleft end of bridge.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 18.96 feet at 

3 p. m. September 20 (discharge, 40,000 second-feet); minimum stage 

during open-water periods, 1.75 feet at 5 p. m. August 6 (discharge, 65- 

second-feet).

1915-1924: Maximum stage recorded, 17.5 feet June 7, 1917 (discharge,, 

31,800 second-feet); minimum stage, 1.56 feet, October 22, 1918 (discharge,, 

estimated 28 second-feet).

ICE. Stage-discharge relation affected by ice.

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

fairly well defined between limits of stage applied. Operation of water 

stage recorder not entirely satisfactory owing to silting of stilling well and 

instrumental troubles. Daily discharge ascertained by applying to rating 

table mean daily gage height determined by inspection of recorder graph or, 

for days having considerable fluctuation in stage, by averaging discharge for 

intervals of the day except for periods given in footnote to table of daily 

discharge. Records fair.

SUGAR CREEK NEAR KEOKUK, IOWA

LOCATION. In sec. 7, T. 65 N., R. 5 W., at single-span highway bridge 6 miles 

northwest of Keokuk, Lee County, on road to Argyle, and Z/z l miles above 

mouth.

DRAINAGE AREA. 113 square miles (measured on county topographic map).

RECORDS AVAILABLE. March 29, 1922, to September 30, 1926.

GAGE. Gurley 7-day water-stage recorder attached to right abutment of bridge; 

installed June 25, 1923; read by Mrs. J. B. Williams.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand; shifting. Left bank is overflowed at high stages. A heavy timber and riprap construction 100 feet 

below gage acts as low-water control; permanent. Elevation of lowest part 

of control, 1.01 feet, referred to gage datum. There is slight leakage through 

control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 10.58 feet at 

8.30 a. m. September 16 (discharge, 3,040 second-feet); minimum stage, 

1.23 feet June 9 (discharge, 0.5 second-foot).

1922-1926: Maximum stage recorded, that of September 16, 1926; 

creek dry at various times.
UPPER MISSISSIPPI RIVER BASIN 123

Maximum known stage, about 20.6 feet June 9, 1905 (discharge, about 

15,000 second-feet). This flood was caused by the same historic storm 

which passed over the adjoining drainage area of Devils Creek and caused 

the destructive flood in that stream.

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

winter. Rating curve well defined below 300 second-feet and fairly well 

defined above. Daily discharge October 1-17 and April 17 to September 

30, when operation of water-stage recorder was satisfactory, ascertained by 

applying to rating table mean daily gage height determined from recorder 

graph or, for days of large fluctuation in stage, by averaging discharge for 

intervals of day; daily discharge November 6-30, February 20 to March 4, 

March 6, and April 15 determined from one daily reading of staff gage. 

Records good for periods when gage operated.

DES PIAINES RIVER AT JOLIET, III,

LOCATION. In NE. % sec. 9, T. 35 N., R. 10 E., at Jackson Street Bridge, Joliet, 

Will County, 1,200 feet upstream from Cass Street Bridge.

DRAINAGE AREA. Indeterminate.

RECORDS AVAILABLE. December 3, 1914, to September 30, 1926; at Cass Street 

Bridge September 5 to December 19, 1914.

GAGE. Gurley 7-day water-stage recorder; inspected by H. A. McCann. Zero 

of gage is 524.31 feet above sea level.

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 year, 15,000 

second-feet April 11; minimum mean daily discharge, 5,240 second-feet 

November 1.

1914-1926: Maximum mean daily discharge during days of record, 18,400 

second-feet, March 18, 1919; minimum mean daily discharge, 5,240 secondfeet, November 1, 1925.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Water is diverted to Illinois & 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 applying 

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

graph. Records excellent, except for periods when water-stage recorder 

was not in operation, for which they are poor.

No discharge measurements were made at this station during the year.

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, 1926; Jamiary 1, 1903, 

to December 13, 1904, for the 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. Zero of gage is 478.97 feet above mean sea level.

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.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 16.4 feet 

April 11 (discharge, 41,000 second-feet); minimum stage, 5.1 feet November 2 (discharge, 7,400 second-feet).

1919-1926: Maximum stage recorded, 20.1 feet April 12, 1922 (discharge, 

60,600 second-feet); minimum stage occurred on November 2, 1925.

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.
136 SURFACE WATER SUPPLY, 1926, PART V

REGULATION. Flow at this station includes the flow from Chicago Drainage 

Canal. Operation of power plants at Lockport and Joliet above gage 

causes slight diurnal fluctuations at low and medium stages.

ACCTJBACY. 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.

COOPEKATION. Gage-height record furnished by United States Weather Bureau.

No discharge measurements were made at this station during the year.

LOCATION. In sec. 2, T. 8 N., R. 8 E., at foot of Grant Street, Peoria, Peoria 

County, 3% miles above station formerly maintained at Peoria & Pekin 

Union Railroad bridge, -antJ; '4j£ miles above mouth of Kickapoo Creek.

DRAINAGE AKEA. Indeterminate.

RECORDS AVAILABLE. March 8, 1910, to September 30, 1926; March 10, 1903, 

to July 21, 1906, for station at Peoria & Pekin Union Railroad bridge.

CAGE. Vertical staff gage attached to wooden pile; read by employee of United 

States Engineer Corps. Zero of gage is 428.92 feet above mean sea level.

DISCHARGE MEASUREMENTS. Made from downstream side of Lower Free Bridge, 

2 miles below gage.

CHANNEL AND CONTROL. Bed of river, which forms control for medium and 

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, 21.6 feet 

September 30 (discharge, 41,500 second-feet); minimum stage, 9.8 feet 

October 11 (discharge, 9,750 second-feet).

1903-1906: Maximum discharge recorded, 57,600 second-feet March 28 

and 29, 1904; minimum discharge, 6,170 second-feet July 18-20, 1906.

1910-1926: 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 

periods fair.

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

The following discharge measurement was made:

April 20, 1926: Gage height, 19.40 feet; discharge, 31,700 second-feet.

ILLINOIS RIVER AT BEAEDSTOWN, ILL.

LOCATION. In sec. 15, T. 18 N., R. 12 W., at highway bridge on State Street, 

Beardstown, Cass County, 9^ miles below the mouth of Sangamon River.

DRAINAGE AREA. 23,445 square miles (since January 17, 1900, the natural 

run-off has been increased by diversion from Lake Michigan through the 

Chicago Drainage Canal).

RECORDS AVAILABLE. October 1, 1920, to September 30, 1926.

GAGE. Vertical staff gage attached to pile on inside of cribbing 40 feet above 

center span of bridge. Zero of gage is 420.33 feet above mean sea level.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Bed composed of sand and mud. Except at very high 

stages control is formed by LaGrange Dam about 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.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 22.2 feet 

September 18-20 (discharge, 71,200 second-feet); minimum stage, 8.3 feet 

October 20 to November 6 (discharge 11,800 second-feet).

1920-1926: Maximum stage recorded, 25.1 feet April 20, 1922 (discharge, 

93,100 second-feet); 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.

ACCURACY. Discharge for a given stage is dependent on slope which varies during 

high-water periods. Rating curves for different slopes are fairly well defined by discharge measurements between 10,700 and 94,000 second-feet 

and for slopes between 0.000010 and 0.000066. Gage read to tenths once 

daily. Daily discharge March 1 to June 30 and September 1-30 determined 

by applying daily gage height to rating curve for slope occurring on that day 

as indicated by stages at Beardstown and LaGrange. Daily discharge 

October 1 to February 28 and July 1 to August 31 determined by applying 

daily gage heights to rating table based on average slope. Records fair.

COOPERATION. Gage-height record furnished by United States Weather Bureau.

The following discharge measurements were made:

October 31, 1925: Gage height, 8.35 feet; discharge, 11,900 second-feet. 

September 17, 1926: Gage height, 22.11 feet; discharge, 69,100 sectond-feet 

(stage-discharge relation slightly affected by backwater from Crooked Creek).

FOX RIVER AT ALGONQUIN, ILL.

LOCATION. In NW. % sec. 34, T. 43 N., R. 8 E. third principal meridian, at 

Chicago Street Bridge in Algonquin, McHenry County, 100 feet above 

Public Service Co.'s dam and 300 feet above Crystal Lake outlet.

RECORDS AVAILABLE.- October 1, 1915, to Septeno&er"30y 1926.

DRAINAGE AREA. 1,340 square miles (measured on base map of Illinois).

GAGE. Staff gage attached to concrete abutment of bridge; read by Edward 

Pedersen to May 29 and by John Filip beginning July 1. Zero of gage is 

729.75 feet above mean sea level.

CHANNEL AND CONTROL. Control is a concrete dam 100 feet below gage; permanent since August, 1919.

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

EXTREMES OP DISCHARGE. Maximum and minimum stages during year not 

obtained.

1916-1926: Maximum stage recorded, 5.3 fdet Maich 31, 1916 (discharge, 

7,120 second-feet); minimum stage, 0.59 foot August 31, 1918 (discharge, 

67 second-feet).

ICE. Stage-discharge relation not affected by ice.

REGULATION. Operation of gristmin at dam below gage was discontinued and 

mill torn down in March, 1926. Stage is occasionally affected during lowwater periods by operation of flashboards on dam 16 miles above gage which 

controls elevation of water surface in Pistakee Lake.

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 from July 1 to September 30. 

Mean monthly discharge October 1 to June 30, estimated, because of doubtful 

gage readings; by comparison with records for Fox River at Dayton, and 

with records for Des Plaines, Pecatonica, and Little Calumet Rivers. Records 

from October 1 to June 30 are poor; records July 1 to September 30'are good.

The following discharge measurements were made:

April 30, 1926: Gage height, 2.08 feet; discharge, 1,340 second-feet.

June 29, 1926: Gage:height, 1.36.feet; discharge, 435 second-feet.

FOX RIVER AT DAYTON, III.

LOCATION. In sec. 29, T. 34 N., R. 4 E., at plant of North Counties Hydroelectric Co., in Dayton, La Salle County, 3 miles below station formerly 

maintained at Wedron, and 6 miles above mouth of river.

DRAINAGE AREA. 2,570 square miles.

RECORDS AVAILABLE. April 13, 1925, to September 30, 1926. From November 

5, 1914, to February 8, 1925, records were obtained at a station at Wedron, 

having a drainage area of 2,500 square miles.

GAGE. Float gages in head and tail race are used for determining head on wheels 

and flow over spillway.

EXTREMES OF DISCHARGE. Maximum mean daily discharge during period of 

record, 11,500 second-feet September 24, 1926; minimum mean daily discharge, 168 second-feet June 22, 1925.
150 SURFACE WATER SUPPLY, 1926, PART V

ACCUBACY. Gages read to tenths hourly. Except during flood periods entire 

flow passes through wheels. Daily discharge through plant is computed from 

mean head, electrical output, and curve of plant efficiency based on manufacturer's ratings. To the discharge through plant is added daily discharge 

over dam as computed'from mean daily head on dam crest, using weir coefficients estimated from data in Water-Supply Paper 200. Records are fair.

COOPEBATION. Power-house data furnished by North Counties Hydroelectric 

Co.

timber growing on banks above low-water stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 16.1 feet 

September 24 (discharge, 9,400 second-feet); minimum stage, 1.30 feet 

October 1-4 and 9 (discharge, 3.3 second-feet).

1914-1926: Maximum stage recorded, 22.9 feet April 20, 1920 (discharge, 

16,500 second-feet); minimum discharge, no flow, August 25-28, September 

16-30, 1920, August 24-27, and September 3 and 4, 1923.

ICE. Stage-discharge relation affected by ice.

ACCURACY. Stage-discharge relation permanent since gage was moved on September 24, 1925. Rating curve well defined by six discharge measurements. 

Gage read to hundredths once daily. Daily discharge for open-water 

periods ascertained by applying daily gage height to rating table. Openwater records good; records during period of ice effect, poor.

The following discharge measurements were made:

April 14, 1926: Gage height, 7.74 feet; discharge, 2,140 second-feet.

July 15, 1926: Gage height, 2.22 feet; discharge, 101 second-feet.

CROOKED CREEK AT RIPIEY, III.

LOCATION. In sec. 33, T. 1 N., R. 2 W., at highway bridge one-fourth mile east

of Ripley, Brown County.

DBAINAGE AREA. 1,310 square miles (measured on base of map of Illinois). 

RECORDS AVAILABLE. March 12, 1921, to September 30, 1926. 

GAGE. Chain gage attached to downstream side of bridge; read by Mrs. John

Hess. Gage was moved to a new bridge about 200 feet downstream from old

location July 28, 1926; datum unchanged.
160 SURFACE WATER SUPPLY, 1926, PART V

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Bed composed of soft mud and clay. Banks high 

and are wooded above medium stage. Control poorly defined; somewhat 

shifting. Illinois River, when at high stage, causes backwater at the station.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 21.5 feet 

June 17 (discharge, 8,850 second-feet); minimum stage, 3.11 feet October 

15 (discharge, 67 second-feet).

1921-1925: Maximum stage recorded 25.0 feet July 25, 1924 (discharge, 

12,500 second-feet); minimum discharge, 9 second-feet September 8 and 9, 

1922.

Old high-watermark, date unknown, is at a stage of about 26.0 feet on gage.

ICE. Stage-discharge relation affected by ice.

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

fairly well defined. Gage read to hundredths once daily. Daily discharge 

ascertained by applying daily gage height to rating table except for periods 

when there was backwater from Illinois River. Records good except for 

periods when discharge was estimated owing to ice effect, missing gage heights, 

or backwater from Illinois River, for which they are poor.

The following discharge measurements were made: 

October 31, 1925: Gage height, 3.25 feet; discharge, 86 second-feet. 

July 28, 1926: Gage height, 3.23 feet; discharge, 87 second-feet. 

September 7, 1926: Gage height, 14.22 feet; discharge, 3,460 second-feet 

(stage-discharge relation affected by backwater from Illinois River).

3 miles northwest of Kane, Greene County.

DRAINAGE AREA. 865 square miles (measured on base map of Illinois).

RECORDS AVAILABLE. March 11, 1921, to September 30, 1926.

GAGE. Vertical staff used prior to July 29, 1926. On July 29, 1926, chain gage 

was installed on bridge and gage datum lowered 3.00 feet. Gage heights 

in this report referred to new datum. Gage read by Claude Linn.

DISCHARGE MEASUREMENTS. Made from bridge or by wading; during high water 

also at bridges over flood channels one-fourth mile south and one-eighth 

mile north of main channel.

CHANNEL AND CONTROL. New channel dredged in summer of 1923 decreased 

the length and increased the slope of the stream. Bed composed of heavy 

clay in dredged channel.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 19.8 feet 

September 5 (discharge, 11,700 second-feet); minimum stage, 2.46 feet 

August 10, 13, and 14 (discharge, 7 second-feet).

1921-1926: Maximum stage recorded, 24.6 feet March 15, 1922 (discharge, 15,000 second-feet); minimum discharge, 1 second-foot September 

29, October 3, 5, and 15, 1922.

High water of 1915 reached a stage of 29.5 feet on present gage.

ICE. Stage-discharge relation slightly affected by ice.

ACCURACY. Stage-discharge relation changed slightly during April. Rating 

curve used October 1 to April 30 well defined between 40 and 300 secondfeet and fairly well defined beyond these limits; rating curve used May 1 

to September 30 fairly well defined. Gage read to hundredths once daily. 

Low-water section of gage washed out February 13; gage heights for low 

stages February 13 to July 28 estimated by observer. Daily discharge 

ascertained by applying daily gage height to rating tables. Records good 

for medium stages and fair for high and low stages. Discharge below 300 

second-feet is poor for the period February 13 to July 28.
