AUTHORIZATION AND SCOPE OF WORK.

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

measurements of flow made on streams in the United States during 

the years ending September 30, 1919 and 1920.

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 in the arid West. Since the fiscal year ending 

June 30, 1895, successive sundry civil bills passed by Congress have 

carried the following item and appropriations:

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 beat methods of utilizing the water resources.

Annual appropriations for the fiscal years ending June SO, 1895-1921.

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 9.

Measurements of stream flow have been made at about 5,000 points 

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

l

Hawaiian Islands. In July, 1920, 1,350 gaging stations were being 

maintained by the Survey and the cooperating organizations. Many 

miscellaneous discharge measurements are made at other points. In 

connection with this work data were also collected in regard to precipitation^ evaporation, storage reservoirs, river profiles, and water 

power in many sections of the country and will be made available in 

water-supply papers from time to time.

DEFINITION OF TERMS.

The volume of water flowing in a stream the "run-off" or "discharge" is expressed in various terms, each'of which has become 

associated with a certain class of work. These terms may be divided 

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

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

water, as run-oS in inches, acre-feet, and millions of cubic feet. The 

principal terms used in this series of reports are seconZPfeet, secondfeet per square mile, and run-off in inches and acre-feet. They 

may be defined as follows:

"Second-feet" is an abbreviation for "cubic feet per second." A 

second-foot is the rate of discharge of water flowing in a channel of 

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

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

unit from which others are computed.

"Second-feet per square mile" is the average number of cubic feet 

of water flowing per second from each square mile of area drained, 

on the assumption that the run-off is distributed uniformly both as 

regards time and area.

"Run-off in inches" is the depth to which an area would be covered 

if all the water flowing from it in a given period were uniformly 

distributed on the surface. It is used for comparing run-off with 

rainfall, which is usually expressed in 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 conn.nfi.on use are here defined:

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

of gage height to discharge."

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

stream below the gage which determine the stage-discharge 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 to which the surface of the stream would 

fall if there were no flow.

EXPLANATION OF DATA.

The data presented in this report cover two years beginning October 

1, 1918, and ending September 30, 1920. At the beginning of January in most parts of the United States much of the precipitation in 

the preceding three months is stored as ground water in the form of 

snow or ice, or in ponds, lakes, and swamps, and this stored water 

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

September, on the other hand, the only stored water available for 

run-off is possibly a small quantity in the ground; therefore the runoff for the year beginning October 1 is practically all derived from 

precipitation within that year.

The base data collected at gaging stations consist of records of 

stage, measurements of discharge, and general information used to 

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 gage or from a water-stage recorder 

that gives a continuous record of the fluctuations. Measurements 

of discharge are made with a current meter. (See Pis. I, II.) The 

general methods are outlined in standard textbooks on the measurement of river discharge.

From the discharge measurements rating tables are prepared that 

give the discharge for any stage, and these rating tables, when applied 

to the gage heights, give the discharge from which the daily, monthly, 

and yearly mean discharge is determined.

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

this report comprise a description of the station, a table giving results 

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 heights and results of discharge measurements 

are published.

The description of the station gives, in addition to statements regarding location and equipment, information in regard to any conditions that may affect the constancy 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
4 SURFACE WATEK SUPPLY, -1919-1920, PAET V.

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

operating on the principle of the planimeter and containing as an 

essential element the rating curve of the.station.

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

gives the mean flow for the day when the mean gage height was 

highest. As the gage height is the mean for the day it does not indicate correctly the stage when the water surface was at crest height, 

and the corresponding discharge was consequently larger than given 

in the maximum column. Likewise, in the column headed "Minimum " the quantity given is the mean flow for the day when the mean 

gage height was lowest. The column headed "Mean" is the average 

flow in cubic feet per second during the month. On this average 

flow computations recorded in the remaining columns, which are 

defined on page 2, are based.

The deficiency table presented for some of the gaging stations shows 

the number of days in each year on which the mean daily discharge 

was less than the discharge given in the table. By subtraction the 

table gives the number of days each year that the mean daily discharge was between the discharges given in the table and, also by 

subtraction, the number of days that the mean daily discharge was 

equal to or greater than the discharge given. If one discharge rating 

table was used throughout the period covered by the deficiency table, 

gage heights that correspond to the discharges are also given.

ACCURACY OF FIEILD DATA AND COMPUTED RESULTS.

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

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

observation of stage, measurements of flow, and interpretation of 

records.

A paragraph in the description of the station gives information 

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

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

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

discharge.1

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 quantity of water flowing past the gage, but the figures 

showing discharge per square mile and depth of run-off in inches 

may be subject to gross errors caused by the (inclusion of large noni For a more detailed discussion of the accuracy of stream-flow data see Grover, N. C., and Hoyt, J. C.,

PUBLICATIONS, d

contributing 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" previously published by the Survey should be 

used with caution because of possible inherent but unknown sources 

of error.

Many gaging stations on streams in the irrigated sections of the 

United States are located 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. Where figures are given these can not be considered exact but as being the best information available.

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

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

estimates; the tables of daily discharge allow more detailed studies 

of the variation in flow. It should be borne in mind, however, that 

the observations in each succeeding year may be expected to throw 

new light on data previously published.

PUBLICATIONS.

Investigation .of water resources by the United States Geological 

Survey has consisted in large part of measurements of the volume of 

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

it has comprised also investigation of such closely allied subjects as 

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

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

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

appeared in the bulletins, professional papers, annual reports, and 

monographs.

The results of stream-flow measurements are now published annually in 12 parts, each part covering an area whose boundaries 

coincide with natural drainage features, as indicated below:

Part I. North Atlantic slope basins.

II. South Atlantic and eastern Gulf of Mexico basins.

III. Ohio River basin.

IV. St. Lawrence River basin.

V. Upper Mississippi River and Hudson Bay basins.

NOTE. No data regarding stream flow are given in the 15th and 17th annual reports.

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 1920. The data for any particular station" will, in general, be 

found in the reports covering the years during which the station was 

maintained. For example, data for Machias River at Whitneyville, 

Me., 1903 to 1920, are published in Water-Supply Papers 97, 124,

GAGING-STATION RECORDS.

HUDSON BAY DRAINAGE BASIN.

ST. MART RIVER NEAR BABB, MONT.

[Including diversion from Swifteurrent Creek.]

LOCATION. In SE. i sec. 27, T. 36 N., R. 14 W., 1,040 feet above headworks of St. 

Mary canal and 2 miles south of Babb, on Blackfeet Indian Reservation, in Glacier 

County.

DRAINAGE AEEA. 278 square miles (including area of Swifteurrent Creek above 

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

RECORDS AVAILABLE.- January 1, 1902, to September 30, 1920. Records for years 

1902 to 1917 containing revisions of previously published records are published in 

Water-Supply Paper 491.

GAGE. Chain gage on right bank used October 1, 1918, to May 14, 1919, August 23 to 

September 4, 1919, October 1 to December*?, 1919, and May 14 to September 30, 

1920. Stevens water-stage recorder on left bank, installed June 15, 1918, at 

same datum as chain gage, used May 15 to August 22, 1919. Auxiliary staff gage 

on right abutment of highway bridge, installed June 14, 1919, used September 

5-30, 1919, and December 16, 1919, to May 13, 1920. During winter of 1917 a 

temporary low-water gage was read, located at site of water-stage recorder. Observer, William Olson.

DISCHARGE MEASUREMENTS. Made from cable 560 feet below gage. In September, 

1909, the cable was moved from a point about 300 feet downstream. Low-water 

measurements are made by wading about 800 feet below gage.

CHANNEL AND CONTROL. Bed composed of gravel and cobble stones; practically 

permanent. Banks high and not subject to overflow. The concrete diversion 

dam for St. Mary canal, located 1,040 feet below gage, forms the control. The 

dam is provided with flashboard sluice gates near the canal headgates. Stagedischarge relation is permanent when the flashboards in the sluice gates remain at 

level of crest of dam and canal headgates are closed.
HUDSON BAY DRAINAGE BASIN. 11

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 5.83 feet at noon May 31 (discharge, 4,740 second-feet); minimum flow 

occurred during the period of maximum ice effect during months of February and 

March (daily discharge not determined).

Maximum stage recorded during year ending September 30, 1920, 5.31 feet 

June 17-19 (discharge, 4,010 second-feet); minimum discharge, 88 second-feet 

March 16-23 and March 29 to April 7 (gage height, 5.05 feet, auxiliary staff gage 

datum).

1902-1920: Maximum stage estimated 9.4 feet June 5, 1908 (discharge, 7,980 

second-feet); minimum stage recorded, 1.0 foot April 3-7, 1904 (discharge, 30 

second-feet).

ICE. Stage-discharge relation affected by ice during severe winters. 

DIVERSIONS. None. 

REGULATION. Flow is regulated by Sherbume Lake reservoir and natural storage in

St. Mary Lakes.

ACCURACY. Stage-discharge relation affected by ice and by operation of gates _of 

canal. Two fairly well defined rating curves used during 1919, applicable October 1 to April 26 and April 27 to September 4. Rating curve used during 1920, for 

open channel with gates closed, well defined for both chain gage and auxiliary 

staff gage. Chain gage read to hundredths once daily October 1, 1918, to May 14, 

1919, and August 23 to September 4, 1919, and to tenths once daily October lr 

to December 7, 1919, and May 14 to September 30, 1920. Mean daily gage 

heights May 15 to August 22,1919, ascertained from Stevens water-stage recorder. 

Auxiliary staff gage read to quarter-tenths once daily September 5-30, 1919, and 

December 16, 1919, to May 13, 1920. Daily discharge ascertained by applying 

daily gage height to rating table except for periods of ice effect and for other 

periods indicated in footnote to tables of daily discharge. Records good for 

periods of open water with canal gates closed; other records fair. 

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

Reclamation Service for the purpose of diverting water from St. Mary River into St. 

Mary canal, which carries the water across the divide into North Fork of Milk River. 

The water then flows in the channel of Milk River through Canada, and is finally 

used for irrigation in the Milk River Valley in Montana. The present capacity of the 

diversion canal is about 425 second-feet. A storage reservoir is provided on Swiftcurrent Creek by a dam at the outlet of Sherburne Lake. By means of a diversion 

channel connecting Swiftcurrent Creek and Lower St. Mary Lake, the run-off from 

Swiftcurrent Creek is made available for diversion through St. Mary canal.

ST. HART RIVER NEAR KIMBALL, ALBERTA.

LOCATION. In SW. J sec. 25, T. 1 N., R. 25 W. fourth meridian, 1 mile south and 1 

mile west of Kimball, Alberta, and 5 miles north of international boundary.

DRAINAGE AREA. 472 square miles (measured on topographic maps).

RECORDS AVAILABLE. January 1, 1913, to September 30, 1920. Erom September 1, 

1902, to December 31, 1912, records were obtained at a point half a mile north 

of the boundary line, and are published in the water-supply papers under the 

heading "St. Mary River near Cardston, Alberta," except in Water-Supply Paper 

491 in which they are published, with revisions, under the heading "St. Mary 

River at Cook's ranch, Alberta, near international boundary." A station was 

maintained by the Alberta Railway & Irrigation Co. at a point half a mile below 

the present station, from 1905 to 1908. It was taken over by the Irrigation 

Branch (now the Reclamation Service), Department of the Interior, Canada, 

in April, 1908, and operated until December 31,1912. The records for this period 

are published in Water-Supply Paper 491 under the heading "St. Mary River 

near Kimball, Alberta, near international boundary." The discharge at the 

three points is practically the same.
14 SUEFACE WATEE SUPPLY, 1919-1920, PAET V.

GAGE. Stevens water-stage recorder with a concrete well and shelter on right bank 

used during,open-water season. During winter a chain gage, attached to the 

highway bridge 3 miles below the station is used. A staff gage at cable from 

which measurements were made was used from October 1, 1917, to November 8, 

1917. Observer, J. M. Dunn.

DISCHARGE MEASUREMENTS. Made from a cable 1,200 feet above gage; low-water 

measurements made by wading near gage.

CHANNEL AND CONTROL. Bed of stream at gage and at control composed of boulders 

and sandstone ledges. Control is formed by an outcropping ledge of sandstone 

covered with boulders near left bank.

EXTREMES OP DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 6.13 feet at 11 a. m. May 30 (discharge, 4,380 secondfeet); minimum discharge, estimated 59 second-feet March 3 (stage-discharge 

relation affected by ice).

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 6.28 feet at 2 p. m. June 18 (discharge, 4,600 second-feet); minimum 

discharge, estimated 46 second-feet December 1 (stage-discharge relation affected 

by ice).

1902-1920: Maximum discharge, 18,000 second-feet, June 5, 1908, estimated 

from the crest stage at the station at Cook's ranch, Alberta, by comparison with 

record for station near Babb; minimum discharge, estimated 46 second-feet a 

December 1, 1919 (stage-discharge relation affected by ice).

ICE. Stage-discharge relation affected by ice during severe winters.

DIVERSIONS. The St. Mary canal, constructed by the United States Reclamation 

Service, diverts water from St. Mary River near Babb, Mont., to the North Fork 

of Milk River. Approximately 141,000 acre-feet were diverted during 1919 and 

about 72,000 acre-feet during 1920. The Alberta Railway & Irrigation Co.'s 

canal diverts water from St. Mary River about 2 miles below the station.

REGULATION. The flow of Swiftcurrent Creek is regulated by the Sherburne Lake 

reservoir.

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

control. Pour rating curves used during open-water periods are well defined; 

applicable October 1 to November 20, 1918, April 17, 1919, to October 20, 1919, 

April 22 to June 18,1920, and June 19 to September 30,1920. Daily gage heights 

obtained from Stevens water-stage recorder records by straight-line method 

October 1 to December 30, 1918, April 1 to October 23, 1919, April 22 to May 2, 

1920, May 4-6, 1920, and May 14 to September 30, 1920. Daily gage heights 

during periods January 1 to March 31, 1919, October 24, 1919, to April 21, 1920, 

and May 8-12, 1920, from observer's readings once daily to hundredths on chain 

gage at highway bridge 3 miles below water^stage recorder. Daily discharge 

ascertained by applying daily gage height to rating table except for periods indicated in footnote to tables of daily discharge. Records good.

COOPERATION. Station maintained in cooperation with the Reclamation Service, 

Department of the Interior, Canada.

* Only estimates 6f mean monthly flow are available for the winter periods from 1902 to 1912, ihelusiv , 

and a lower minimum discharge may have occurred during that time.

NOTE. For tables of monthly discharge of St. Mary canal at St. Mary crossing, see p. 23. 

ST. HART CANAL AT INTAKE, NEAR BABB, MONT.

LOCATION. In NW. J sec. 27, T. 36 N.,-R. 14 W., 600 feet below intake of canal and

2 miles south of Babb, on Blackfeet Indian Reservation, in Glacier County. 

RECORDS AVAILABLE. June 1, 1918, to August 31, 1920. 

GAGE. Gurley printing water-stage recorder in wooden shelter on right bank. Prior

to April 17,1919, a staff gage 300 feet above present gage was read. The two gages

were set to read the same but are not at the same datum on account of the slope

in canal between the two points. 

DISCHARGE MEASUREMENTS. Made from cable 10 feet above gage. Current is evenly

distributed throughout 'cross section and has a moderate velocity at all stages. 

CHANNEL AND CONTROL. Bed composed of gravel. Repairs to canal may cause slight

changes in stage-discharge relation. 

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September

30, 1919, 6.23 feet May 15 (discharge, 550 second-feet). 

Maximum stage recorded during year ending September 30, 1920, 7.04 feet

August 8 (discharge, 655 second-feet). 

1918-1920: Maximum stage recorded, 7.04 feet August 8, 1920 (discharge, 655

second-feet). 

ICE. Canal not operated during winter.
20 SURFACE WATER SUPPLY, 1919-1920, PART V.

ACCURACY. Stags-discharge relation changed during period June 2 to July S,

when channel was being repaired; permanent during other periods. Two rating 

curves used during 1919, the first, applicable April 18 to June 1, is fairly well 

defined between 130 and 552 second-feet, and the second, applicable July 9 to 

September 30, is well defined between 20 and 512 second-feet. Rating curve 

used during 1920 is well defined between 10 and 650 second-feet. Operation of 

water-stage recorder unsatisfactory during 1919; gage heights were obtained from 

observer's readings twice daily to hundredths on staff gage 300 feet upstream from 

recorder. Gage heights during periods June 25 to August 12, and August 25-31, 

1920, were obtained from Gurley printing water-stage recorder records; observer's 

readings once daily to hundredths on staff gage 300 feet upstream from recorder, 

used for other periods during 1920. Daily discharge, April 18 to June 1, 1919, ascertained by applying mean daily gage height to rating table; June 2 to July 8,1919, 

by indirect method for shifting control; Jun'e 25 to August 12, 1920, and August 

25-31,1920, by applying mean daily gage height from Gurley printing water-stage 

recorder to rating table, and during other periods in 1920 by applying observed 

daily gage height to rating table. Records prior to July 9,1919, are fair and thereafter during 1919 they are good. Records for 1920 are excellent.

COOPERATION. Station maintained in cooperation with Reclamation Service, Department of the Interior, Canada.

St. Mary canal diverts water from the west bank of St. Mary River near Babb, 

Mont., and discharges into the North Fork of Milk River. The water then flows in 

the natural channel of Milk River through Canada and is finally used for irrigation 

in the Milk River Valley east of Havre, Mont. Water may be returned to the St. 

Mary River at St. Mary crossing.

24 SURFACE WATER SUPPLY, 1919HL920, PART V.

ST. MARY CANAL AT HUDSON BAY DIVIDE, NEAR BROWNING, MONT.

LOCATION. In NE. £ sec. 5, T. 37 N., R. 11 W., on Hudson Bay Divide, 12 feet above 

first concrete drop in canal, on Blackfeet Indian Reservation, a quarter of a mile 

south of international boundary, and 30 miles north of Browning, in Glacier 

County.

RECORDS AVAILABLE. July 3, 1917, to August 31, 1920.

GAGE. Stevens water-stage recorder in wooden shelter on left bank used since June

29. 1920. The recorder was on right bank 40 feet above present site during 1919

and from May 25 to June 28, 1920. Prior to 1919 a staff gage at different datum

located at Douglas bridge 1 mile above was used. 

CHANNEL AND CONTROL. Canal has uniform section. At high stages the slope of

water surface changes slightly with the change in stage. Control is a V-shaped

notch in the concrete drop 12 feet below gage. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September

30. 1919, 6.20 feet at 7 p. m. May 15 (discharge, 416 second-feet).

Maximum stage recorded during year ending September 30, 1920, 5.92 feet at 

6 p. m. August 9 (discharge, 472 second-feet).

1917-1920: Maximum discharge recorded, 472 second-feet at 6 p. m. August 9, 

1920.

ICE. Canal not operated during winter.

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

October 24-26, 1919. Rating curve used during 1919 is fairly well defined for all 

stages. Two well-defined rating curves used during 1920, applicable respectively, 

May 26 to June 28 and June 29 to August 31. Mean daily gage height obtained by 

inspection from water-stage recorder graph. Daily discharge ascertained by 

applying mean daily gage height to rating table except for periods May 26-29, and 

September 22, 23, and 27-29, 1919, for which it was ascertained by hourly-discharge method and except for period October 24-26, 1919, when stage-discharge 

relation was affected by ice for which it was estimated. Records excellent.

COOPERATION. Station maintained in cooperation with Reclamation Service, Department of the Interior, Canada.

Discharge measurements of St. Mary canal at Hudson Bay divide, near Browning, Mont., 

during the years ending Sept. SO, 1919 and 1920.

SWIFTCURRENT CREEK AT MANY GLACIER, MONT.

LOCATION. In sec. 12, T. 35 N., R. 16 W., at outlet of McDermott Lake at Many Glacier, in Glacier National Park, 14 miles southwest of Babb, in Glacier County. 

DRAINAGE AREA. 31.4 square miles (measured on topographic map). 

RECORDS AVAILABLE. June 6, 1912, to September 30, 1920.
26 SURFACE WATER SUPPLY, 1919^-1920, PART V.

GAGE. Stevens continuous water-stage recorder installed June 15, 1918, in shelter 

built by park officials and Great Northern Railway, and referred to two staff gages, 

one inside well and one outside. Prior to May 23, 1916, a staff gage on the left 

bank opposite the present gage was read. May 23,1916, to June 15,1918, a vertical staff at same location as present gage was read. Gage read by A. Pullman and 

C. N. McGillis.

DISCHARGE MEASUREMENTS. Made by wading above crest of falls or 1,000 feet below 

at low stage. Since June 26,1920, high-water measurements made from cable 1,000 

feet below gage; prior to that date from highway bridge above power house. 

Section at bridge is poor.

CHANNEL AND CONTROL. Control is limestone outcrop at outlet of lake; shifts slightly. 

Just below control is a fall and a cataract.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30,1919,4.00 feet at 1 a; m. May 28 (discharge, 1,100 second-feet); minimum stage, 

1.40 feet January 14-16 (discharge, 23 second-feet).

Maximum stage recorded during year ending September 30, 1920, 3.86 feet at 

noon June 16 (discharge, 1,020 second-feet); minimum stage, 1.35 feet at 8.30 a. m. 

March 8 (discharge, 18.5 second-feet).

1912-1920: Maximum stage recorded, 4.75 feet June 17, 1916 (discharge, 1,550 

second-feet); minimum discharge, 8.7 second-feet April 1, 1913, by current-meter 

measurement (stage-discharge relation affected by ice).

ICE. Stage-discharge relation occasionally affected by ice.

DIVERSIONS. None.

REGULATION. None.

ACCURACT. Stage-discharge relation changed during 1919 and was affected by ice for 

a short period; permanent during 1920. Two rating curves used during 1919, one, 

applicable October 1 to May 28, is fairly well defined, and the other, applicable 

May 29 to September 30, is well defined. Rating curve used during 1920 is well 

defined between 60 second-feet and 400 second-feet and fairly well defined above 

400 second-feet. Gage heights obtained from Stevens water-stage recorder graph 

by straight-edge method October 1-9, October 20 to November 17,1918, April 16 to 

October 14,1919, May 26 to June 20, June 25 to August 16, and August 19 to September 20, 1920. Observer's readings once daily to hundredths used November 

18, 1918, to April 15, 1919, and mean of two readings daily to hundredths used 

October 15, 1919, to March 31, 1920. Daily discharge ascertained by applying 

mean daily gage height to rating table except for periods indicated in footnote to 

tables of daily discharge. Records fair October 1, 1918, to May 28, 1919; thereafter good.

gWEFTCTTRRENT CREEK AT SHERBURNE, MONT.

i.

LOCATION. In sec. 35, T. 36 N., R. 15 W., 800 feet below spillway of Sherburne Lake

;. > dam, in Glacier County.

DRAINAGE AREA. 64 square miles (measured on topographic map).

RECORDS AVAILABLE. July 1,1912, to September 30,1920.

GAGE. Staff gage on left bank about 800 feet below the spillway of Sh'erburne Lake

' dam, installed August 10,1920. From July 1,1912, to November 9,1914, a vertical staff gage was maintained on the left bank near outlet of lake and at a different datum from present gage. From November 10, 1914, to August 9, 1920, 

a staff gage on left bank about 300 feet below the spillway of Sherburne Lake dam 

was read. Observed by R. R. McComb and others.

DISCHARGE MEASUREMENTS. Made from cable 450 feet above gage or by wading.

CHANNEL AND CONTROL. An outcropping limedtpne ledge, somewhat broken and 

irregular, forms the control; subject to slight shifts.

EXTREMES 07 DISCHARGE. Maximum stage recorded during year ending September 

30,1919,5.90 feet May 29 and 30 (discharge, 950 second-feet); minimum discharge, 

practically no flow, occurred when gates in dam were closed.

Maximum stage recorded during year ending September 30, 1920, 7.45 feet 

August & (discharge, 1,490 second-feet); minimum discharge, practically no flow, 

occurred when gates in dam were closed!

1912-1920: Maximum stage recorded, 7.85 feet June 17, 1916 (discharge, 2,280 

second-feet); minimum discharge, practically no flow occurs when gates in dam 

are closed.
HUDSON BAY DRAINAGE BASIN.

ICE. Stage-discharge relation not seriously affected by ice. < * . . DIVERSIONS . N one.

REGULATION. Flow regulated by gate operations. A record of gate operations has 

been obtained except during the period June 26 to September 30,1919, and flow 

for days during that period when there were sudden changes in gate openings may 

be considerably in error. i

ACCURACY. Stage-discharge relation changed October 17, 1918, and a landslide 

August 10, 1920, necessitated moving the gage 500 feet downstream; affected by 

ice for a short period during winter of 1918-19. Four rating curves used; the 

first, applicable October 1-17, 1918, is well defined between 60 and 1,200 secondfeet; the second, applicable October 18, 1918, to September 30, 1919, is fairly 

well defined throughout; the third, applicable October 1, 1919, to May 6, 1920, 

and August 5-9,1920, is fairly well defined between 30 and 550 second-feet; and 

the fourth, applicable August 10 to September 30,1920, is well defined between 

90 and 300 second-feet. Shifting-control method used May 7 to June 28 and 

July 15 to August 4, 1920. Gage read twice daily to hundredths in 1919 except 

during high water, when it was read to tenths, and once daily to half-tenths or 

quarter-tenths during 1920. Daily discharge ascertained by applying daily gage 

height to rating table except for periods for which shifting-control method was 

used and other periods indicated in footnote to tables of daily discharge. 

Records good during 1919 except for periods of regulated low flow, for which they 

are fair. Records during 1920 prior to August 10, fair; subsequent records good,

September 1, 1914, gage readings were obtained from a vertical staff attached to 

the breakwater for the center pier of Front Street bridge; this gage is still maintained and used by the Weather Bureau, but can not be read accurately without 

a field glass and has a less permanent control than the gage now used. At the same 

stage, after complete submergence of the dam, readings on the Front Street gag* 

are numerically about 10.4 feet greater than on the gage now used.

DISCHARGE MEASUREMENTS. Made from footbridge & few feet upstream from gag»

CHANNEL AND CONTROL.- Bed composed of clay and silt; nearly permanent. Con* 

trol is timber and steel crib dam, rock filled, below gage; has settled a few inches 

since construction. At extreme low stage the fall ove* the dam is about 5 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 2.7 feet March 22, April 5 and 7, and May 12 (discharge, 630 secondfeet); unmiimini discharge, estimated 29 second-feet February 12 (stage-discharge 

relation affected by ice).

Maximum stage recorded during year ending September 30, 1920, 13.5 feet at 

2 p. m. March 27 (discharge, 6,200 second-feet); minimum discharge, estimated 

55 second-feet December 5 (stage-discharge relation affected by ice).

1901-1920: Maximum stage recorded, 29.8 feet March 30,1907 (etage-dischaxgt 

relation affected by ice); maximum open-watet stage recorded, 17.34 feet July ll» 

1916 (discharge, 7,740 second-feet); minimum stage recorded, 1.0 foot February 

11,1918 (discharge not determined).
HUDSON BAY DKAIKAGE BASH*.

ICB. Stage-discharge relation cot seriously affected by ice.

DIVERSIONS. None.

REGULATION. No power plants or storage above station within 60 miles; storage 

not great enough to noticeably affect the discharge at station.

ACCURACY. Stage-discharge relation changed during 1919 owing to settling of the 

dam; affected by ice during 1919 and 1920. Two rating curves used, one, 

applicable October 1,1918, to April 30, 1919, is well defined between 60 and 

4,400 second-feet, the other, applicable March 1, 1919, to September 30, 1920, 

is well defined between 45 and 4,400 second-feet. Gage read to tenths once 

daily except during periods indicated in footnote to tables of daily discharge. 

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

for periods indicated in footnote to tables of daily discharge. Open-water 

records good; other records lair.

RED RIVER AT GRAND FORKS, N. DAK.

LOCATION. At Northern Pacific Railway bridge between Grand Forks, N. Dak., and 

East Grand Forks, Minn,, half a mile below mouth of Red Lake River, in Grand 

Forks County.

DRAINAGE AREA. 25,000 square miles.

RECORDS AVAILABLE. May 26,1901, to September 30,1920; gage-height records have 

been kept by the United States Engineer Corps since 1882 and a few discharge 

measurements were made by them in early years.

GAGE. Vertical staff gage with enameled face, attached to ice-breaker below center 

pier of Northern Pacific Railway bridge; installed by United States Weather 

Bureau during winter of 1916-17 beside old Geological Survey staff gage which 

was used prior to 1917, but at a datum 5 feet higher. The observer, H. L. Hayes, 

adds 5 feet to gage readings to reduce them to datum of old Geological Survey 

gage. Another vertical staff gage attached to the ice-breaker beside the enameled 

gage, and at the same datum, is used by the United States Engineer Corps. Prior 

to 1918, when the railway bridge was partially rebuilt, a chain gage, attached to 

the middle span of the bridge, was maintained for use in case the staff gages 

were destroyed. This chain gage has not been replaced since 1918.

DISCHARGE MEASUREMENTS. Made from Great Northern Railway bridge a quarter 

of a mile above gage.

CHANNEL AND CONTROL. Bed composed of clay and silt; shifts slightly.
SURFACE WATER SUPPLY, 101&-1900, PABT V.

OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 23.2 feet July 8 (discharge, 13,600 second-feet); minimum discharge, 

estimated 263 second-feet February 27 and 28 and March 1 (stage-discharge relation affected by ice).

Maximum discharge during year ending September 30, 192fo, estimated 30,3@0 

second-feet March 31 (sfage^ischarge relation* affected by ice)| minimum isciiarge; estimated 590 second-feet February 21 and 23 <stage-discnarge fetation 

affected by ice).

1882-1920: Maximum stage recorded, 50.2 feet April 10y 1897 (discharge, 43,000 

second-feet); minimum discharge, about 100 second-feet during early part of 

February, 1912 (stage-discharge relation affected by ice).

ICE. Stage-discharge relation seriously affected by ice. The ice cover is usually complete and smooth from late in November until about the beginning of April 

and the flow steady with few fluctuations; in determining flow during spring 

break-up, however, corrections amounting to several feet at times must be applied 

to gage heights before applying them to open-water rating table dwing to Backwater from ice jams.

DIVERSIONS. None.

REGULATION. No power plants above with sufficient storage to cause noticeable 

variations in the flow.

ACCURACY. Stage-discharge relation affected by ice and by slight shifts in control. 

One rating curve used during 1919 and 1920; well defined between 640 and 16,300 

second-feet. Gage read to tenths twice daily during 1919 and during open-water 

season of 1920 and usually twice a week during period of ice effect in 1920. Daily 

discharge ascertained by applying mean daily gage height to rating table 

except for periods indicated in footnote to tables of daily discharge. Openwater records good; winter records fair.

NOTE. Stage-discharge relation affected by ice Dec. 14,1918, to Apr. 4,1919, and Nov. 4,1919, to Mar. 

31,1920; discharge ascertained, for days when gage was read, by correcting mean daily gage height for 

backwater from ice and applying corrected gage height to rating table, and interpolating for days when 

gage was not read, except during period Jan. 1 to Feb. 29,1920, for which mean discharge was estimated 

as follows: Jan. 1-31,690 second-feet; Feb. 1-29,670 second-feet. During periods of ice effect the gage was 

not read on the following days: Jan. 17,18, Dee. 21,23-26,28,30.31,19W; Jan. 1,2, 4,6-9,11-16,18,20-23,

BOI8 DBS SIOUX RIVER NEAR TENNEY, MINK.

LOCATION. Near center of sec. 22, T. 130 N., R. 47 W., at Soo Railway bridge, 2 

miles east of Fairmount, N. Dak., 5 miles west of Tenney, Wilkin County, Minn., 

and 15 miles below outlet of Lake Traverse.

DRAINAGE AREA. 1,460 square miles.

RECORDS AVAILABLE. April 1 to September 6, 1919, and April 1 to September 30, 

1920. . i

GAGE. Vertical staff attached to face of eighth pile-pier from left end of railway 

bridge, used August 24 to September 30, 1920. Vertical staff attached to sixth 

pile-pier from left end of railway bridge, used April 1 to August 23,1920; at same 

datum as staff gage on eighth pile-pier. Vertical staff attached underneath right 

end of highway bridge half a mile above railway bridge, used April 1 to September 

6, 1919. Owing to change in slope of water surface, the gage at the highway 

bridge does not read the same as the gage at the railway bridge for other than low 

stages. Gage readers, B. W. Schouweiler, J. H. Bolton, and Math Schmit.

DISCHARGE MEASUREMENTS. Made from highway bridge hall a mile upstream from

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

plants which may, at low stages, materially affect stage-discharge relation. Shifts 

not likely to occur for normal velocities are not swift enough to erode channel.
HUDSON" BAY DRAINAGE BASI13V 41

EXTREMES OF DISCHARGE. Maximum stage recorded during period^April 1 to September 6, 1919, 4.1 feet August 4-6 (discharge, 77* second-feet); minimum stage, 

1.5 feet April 5 (discharge, 6 second-feet).

Maximum discharge recorded during period April 1 to September 30, 1920, 

214 second-feet April 2 and 3 (gage height, 5.0 feet); gage height June 11 and 12 

was 5.2 feet but stage-discharge relation was affected by obstructions in channel; 

minimum stage, 3.3 feet September 21-23 (discharge, 43 second-feet).

1919-20: Maximum discharge recorded during period occurred during 1920; 

minimum discharge occurred during 1919.

ICE. Station not operated during winter.

DIVERSIONS . None.

REGULATION. No reservoirs or power plants affect the flow: No large tributaries 

enter between outlet of Lake Traverse and the station and abrupt changes in 

stage are unusual. Extensive ditching and drainage work in the area above 

station within recent years, undoubtedly affects the distribution of flow.

ACCURACY. Stage-discharge relation affected, at low stages, by heavy growth of 

aquatic plants. Rating curve used during period of record in 1919, referred to 

gage at highway bridge, fairly well defined between 7 and 47 second-feet. Rating 

curve used during period of record in 1920, referred to gages at railway bridge, 

fairly well defined between 6 and 166 second-feet. All gages read to half-tenths 

once daily except on days indicated in footnote to tables of daily discharge. 

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

interpolating for days when gage was not read except for periods when flow was 

affected by growth of aquatic plants for which it was ascertained by applying to 

rating table the daily gage height corrected for backwater, the amount of which 

had been determined by discharge measurements, and interpolating for days 

when gage was not read. Records good except for periods when flow was affected 

by growth of aquatic plants for which they are fair.

COOPERATION. Station maintained during 1919 in cooperation with the Bureau of 

Public Roads, Department of Agriculture, and during 1920 in cooperation with 

the Department of Drainage and Waters, State of Minnesota.

Discharge measurements of Bois des Sioux River near Tenney, Minn., during tile years 

ending September 30,1919 and 1920.

HUDSON BAY DBAINAGE BASIN.

MUSTINKA RIVER ABOVE WHEAT ON, MINN.

LOCATION. On line between sees. 7 and 8, T. 127 N., R. 46 W., at steel-concrete 

highway bridge 1 mile upstream from Chicago, Milwaukee & St. Paul Railway 

bridge, 1J miles northeast of Wheaton, Traverse County, and 8 miles above Lake 

Traverse, into which the river discharges.

DRAINAGE AREA. 776 square miles. 3

RECORDS AVAILABLE. March 23 to September 30,1917, and June 25,1919, to September 30, 1920. June 7 to November 30, 1916, at point about 3J miles downstream.

GAGE. Chain gage attached to highway bridge; read by Vernon Heggen. An auxiliary staff gage, for use during floods, is attached to the Chicago, Milwaukee & St. 

Paul Railway bridge 1 mile downstream from chain gage.

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

or from steel highway bridge just below Chicago, Milwaukee & St. Paul Railway 

bridge; about 1J miles downstream from gage. Measuring section at gage poor 

onlbecount of angle of current; best section at steel highway bridge below the railway bridge. Flow of drainage ditch which carries water around gage must be 

included in all measurements made from bridge to which gage ia attached.

CHANNEL AND CONTROL. Bed composed of firm gravel overlain with thin deposits 

of clay and silt; practically permanent. Control not well defined. Slope of river 

from station to Lake Traverse is so slight that the stage-discharge relation may 

possibly be affected by changes of stage of the lake.

EXTREMES OP DISCHARGE. Maximum stage recorded during period June 25 to September 30, 1919, 7.37 feet June 25 (discharge, 559 second-feet); minimum stage, 

1.12 feet September 25 (discharge, 0.3 second-foot).

Maximum discharge during year ending September 30, 1920, 970 second-feet 

May 11 (gage height, 9.5 feet); gage height 11.02 feet March 24 (stage-discharge 

relation affected by ice); minimum stage recorded, 1.10 feet October 9 (discharge, 

0.2 second-foot).

1917; 1919-20: Maximum stage recorded during periods, 14.7 feet April 1, 1917 

(discharge, 2,340 second-feet); minimum stage, 1.10 feet October 9, 1919 (discharge, 0.2 second-foot).

ICE. Station not operated during winter.

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

in March, 1920. One rating curve used during 1919 and 1920; fairly well defined 

between 4 and 2,400 second-feet. Gage read to hundredths once daily. Daily 

discharge ascertained by applying daily gage height t6 rating table except for 

periods indicated in footnote to tables of daily discharge. Records good.

COOPERATION. Station operated during 1919 by Bureau of Public Roads, Department 

of Agriculture, and during 1920 in cooperation with the Department of Drainage 

and Waters, State of Minnesota.

LOCATION. At steel footbridge near Elk's House, 40 rods west of Northern Pacific Railway depot at Valley City, Barnes Gaunty.

DRAINAGE AREA. 4,300 square miles.

RECORDS AVAILABLE. March 24 to August 29,191% when station wag discontinued.

GAGE. Vertical staff attached to steel pier at south end of footbridge; read by K. C. 

Schmidt.

DISCHARGE MEASUREMENTS. Made from footbridge or by wading.

CHANNEL AND CONTROL. Bed composed of silt and fine clay. Control is a concrete 

dam about half a mile below gage. A broad-crested weir on the crest of the dam 

acts as control at low stages. The weir crest is 2 feet wide, 49 feet long, and at an 

elevation 1 foot below crest of dam; elevation of weir crest, referred to gage datum, 

6.38 feet. Submergence of the dam begins at stage about 8 feet, and at 10 feet 

submergence is practically complete.

EXTREMES op DISCHARGE. Maximum stage recorded during period, 14.9 feet April 

18 (discharge, 2,750 second-feet); minimum stage, 6.14 feet August 28 (discharge, 

3 second-feet).

ICE. Station operated for only a short period during winter.

REGULATION. No dams above have sufficient storage capacity to affect the flow for 

more than a single day.
HUDSON BAY DBAIFAGE BASIN. 47

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

defined between 3 and 2,800 second-feet. Gage read to tenths or hundredths once 

daily during periods of high water; .readings obtained irregularly during other 

periods. Daily discharge for days when gage was read, ascertained by applying 

daily gage height to rating table except for period March 24 to April 3, when stagedischarge relation was affected by ice, .for which it was ascertained by applying to 

rating table the daily gage height corrected for backwater from ice. Discharge 

interpolated for days when gage was not read. Records fair.

DEVILS LAKE NEAR DEVILS LAKE, N. DAK.

LOCATION. At biologic station of University of North Dakota, on shore of Creels Bay, 

6 miles southwest of city of Devils Lake, in Ramsey County.

DRAINAGE ABBA. The theoretical drainage area of the lake is about 3,710 square 

miles. In years of ordinary rainfall water reaches the lake from only a very 

small part of this area, for most of it drains into local depressions and small lakes, 

where it remains until lost by evaporation. By survey in 1883, the length of the 

lake was found to be 35 miles, and its area 115 square, miles. It was a continuous 

body of water then, but at present it is divided, by sand bars and roadways, into 

three separate large lakes and at least 8 smaller ones, the combined area of which 

is only about 52 square miles. In 1920 the elevation of the water surface of some 

of these lakes differed by 3 or 4 feet. At present, the greatest depth of water is 

about 20 feet.

RECORDS AVAILABLE. June 7, 1901, to September 30, 1920 (fragmentary). A few 

records were obtained in earlier years.

GAGE. Staff gage attached to pier at biologic station. Occasionally the gage is 

damaged or removed by ice during spring break-up, but is replaced by reference 

to several bench marks in the vicinity. Zero of gage, 1,416.2 feet above sea-level. 

Read occasionally by employees of the biologic station.

REGULATION. The lake has no outlet. The stage of the lake shows the relation 

between evaporation from the lake surface and the inflow from the surrounding 

country and gives an indication of whether the run-off has been affected by the 

settlement and cultivation of the land surface of the drainage area.

COOPERATION. Records furnished by North Dakota Biological Survey.

RED LAKE RIVER AT THIEF RIVER FALLS, MINN.

LOCATION. In sec. 33, T. 154 N., R. 43 W., a third of a mile below dam at Thief River 

Falls, Pennington County, and 1 mile below mouth of Thief River, which enters 

from right.

DRAINAGE AREA. 3,430 square miles.

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

GAGE. Inclined staff gage on right bank; read by Dedrick Knutson. During period 

April 2 to August 18, when it was impossible to install inclined gage on account 

of high stage of river, a series of temporary vertical staff gages was used.

DISCHARGE MEASUREMENTS. Made from cable 100 feet above gage.

CHANNEL AND CONTROL. Gravel and small boulders; practically permanent.

EXTREMES OF DISCHARGE. Maximum open-water stage recorded during year, 9.2 feet 

April 16 (discharge, 3,700 second-feet); minimum stage, 4.3 feet August 17 tod 

18 (discharge, 290 second-feet).

1909-1918: Maximum open-water stage recorded, 12.2 feet April 19-21, 1916 

(discharge, 7,040 second-feet); minimum discharge recorded, no flow, July 17 and 

August 27, 1911; caused by regulation.

ICE. Stage-discharge relation seriously affected by ice.

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

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

due to the 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 well defined between 20 and 5,600 second-feet. Gage read to half-tenths 

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

table except for period March 25 to April 9, when stage-discharge relation was 

affected by ice, for which it was ascertained by applying to rating table the daily 

gage height corrected for backwater from ice, and except for March 31 and July 23 

for which discharge was interpolated on account of lack of gage readings. Daily 

discharge for some days in error on account of fluctuations in stage caused by 

operation of lighting plant and mill just above gage. Open-water records for days 

of no fluctuation excellent; records for other periods fair.

COOPERATION. Station maintained in cooperation with the Department of Drainage 

and Waters, E. V. Willard, commissioner.

BED LAKE RIV5R AT CROOKSTON,

LOCATION. In see. 30, T. 160 N., R. 46 W., at new Sampson's Addition highway 

bridge in Orookston, Polk County, a quarter of a mile below dam and power house 

of Crookston Light, Water & Power Co.'s plant. No tributaries enter for several 

miles.
52 SUEFACE WATER SUPPLY, 1919-1920, PAET V.

DRAINAGE AREA. 5,320 square miles.

RECORDS AVAILABLE. May 19, 1901, to September 30, 1920.

GAGE. Barrett & Lawrence water-stage recorder, on right abutment of bridge; 

installed in September, 1911, replacing chain gage attached to bridge July 1, 

1909. Both gages at same datum. During 1920 the water-stage recorder was not 

operating and the chain gage was used. Prior to July 1, 1909, gage was on old 

Sampson's Addition bridge, about 300 feet farther upstream; this gage read the 

same as prerent one at ordinary stages. Observer in 1919, S. V. Holder; in 

1920, M. J. Dean.

DISCHARGE MEASUREMENTS. Made from steel highway bridge to which gage is 

attached.

CHANNEL AND CONTROL. One channel at all stages. Bed composed of silt, gravel, 

and small boulders; slightly shifting. Control not well defined.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 21.1 feet July 5 (discharge, about 14,700 second-feet); minimum openwater stage from water-stage recorder, 2.5 feet October 10 and 16 (discharge, 88 

second-feet).

Maximum open-water stage recorded during year ending September 30, 1920, 

10.8 feet April 16 (discharge, 5,230 second-feet); maximum discharge estimated 

10,100 second-feet March 25 (stage-discharge relation affected by ice); minimum 

stage recorded, 3.4 feet September 3 (discharge, 358 second-feet). Records 

fragmentary for this year and probably the true maximum and minimum were 

missed.

1901-1920: Maximum open-water stage recorded during period, 21.1 feet July 5, 

1919 (discharge, about 14,700 second-feet); minimum discharge recorded, 10 

second-feet by current-meter measurement made January 27, 1912. The flow 

is controlled to such an extent that the minimum recorded discharge has no 

bearing on the minimum natural flow.

ICE. Stage-discharge relation seriously affected by ice.

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

power plant immediately above station. The plant has little storage, so that the 

mean monthly flow should represent nearly the natural flow.

ACCURACY. Stage-discharge relation practically permanent. One rating curve 

used during 1919 and 1920; well denned at all stages. Operation of water-stage 

recorder fairly satisfactory during 1919; not operating during 1920, and chain gage 

was read to tenths once daily. Daily discharge during 1919, ascertained by applying to rating table mean daily gage height obtained l^y planimetering the waterstage recorder graph, and during 1920 by applying daily gage height to rating table 

except for periods indicated in footnote to tables of daily discharge. Openwater records during 1919, excellent; other records, fair.

RED LAKE SIVER FLOOD OF JULY, 19W.

Unusual floods occurred on Red Lake River at and above the gaging station at 

Crookston, Minn., during the first week of July, 1919, as a result of heavy rainstorms 

that extended over the whole drainage area.

The precipitation occurred on July 1, 2, and 3, although at most points the 

storm did not continue more than 48 hours and had ended by the morning of July 

3. The precipitation for the three days at each of the five United States Weather 

Bureau stations within the area ranged between 5.3 and 6.9 inches, and the total rainfall at each of the 13 nearest stations surrounding this area ranged for this period 

between 1.1 and 9 inches. From all these the isohyetal average for the drainage 

area of Red Lake River above Crookston during the three days is found to be 5.7 

inches. The ensuing floods on the river and its tributaries much surpassed any ever 

recorded in the summer since stream-gaging work was begun, and are said to be higher 

than any open-water floods since the country was first settled by white men 40 or 50 

years ago.

The drainage area of Red Lake River above the gaging station at Crookston, Minn., 

is 5,320 square miles. The gaging station is 30 miles above the month of the river, 

and the extreme low stage there is 2.2 feet. Continuous records during the flood were 

obtained, showing a rise from a stage of about 6 feet (discharge, 1,600 second-feet) 

on July 2 to a maximum height of 21.1 feet (discharge, 14,700 second-feet) on the 

afternoon of July 5; mean gage height for July 5, 20.8 feet. On July 6, 7, and 8 the 

mean gage height was 20,17.6, and 15.7 feet, respectively. Thereafter the stage fell 

gradually to a height of 6.5 feet (discharge, 1,950 second-feet) at the end of July.

The gaging station at Crookston has been maintained since May 19,1901, and since 

thtat date the maximum stage reached during the flood of 1919 has never been exceeded 

except on April 17,1916X when a stage of 21.8 feet was recorded, and on March 25,1920, 

when a gage height of 23.3 feet was reached. Before gage-height records were kept 

regularly, a height of 25.2 feet has been well authenticated for April 11 either of the 

year 1896 or 1897. On April 24,1904, a gage height of 20.3 feet occurred, and on April 

15,1906, 21 feet was recorded. However, all of these stages occurred at the time of 

the ice break-up, when the velocity of flow is considerably retarded by floating and 

jammed ice; hence it is doubtless true that the discharge of July 5,|1919,Swas greater 

than any which has ever before occurred within a 40-year period.

At Huot Bridge, 15 miles above Crookston, the highest stage since 1975 and prior to 

1920 occurred during the spring break-up of 1896 or 18^7, at which time the high-
HUDSON BAY DRAINAGE BASIN. 55

water elevation was permanently marked by residents; this high stage was in part 

caused by ice jams. But on March 24, 1920, an ice jam (after the breaking of which 

the water fell 6 feet in less than 12 hours) raised the water level about 2 feet above the 

high-water mark of 1896-97. The stage of July 4 or 5,1919, was said by residents to 

be next highest to the 1896-97 stage, it being 3.3 feet lower.

The only important tributaries of Red Lake River are Black, Clearwater, and Thief 

rivers. Black River enters about 23 miles, by river, above Crookston, and drains 

about 200 square miles. No record of its flow was obtained, but it is not thought to 

have been an important contributor to the flood.

The chief tributary is Clearwater River, which drains 1,310 square miles, and enters 

Red Lake River at Red Lake Falls, 25 miles above Crookston. A gaging station on 

Clearwater River was maintained at Red Lake Falls from 1909 to 1917. The extreme 

low stage is 1.6 feet. The rise at this station began at noon July 2, and on the afternoon 

of July 3 the maximum gage height, &.7 feet (discharge, 6,700 second-feet}, was reached. 

From this height there was a gradual fall to a stage of 6.9 feet at noon July 7, and to 

6.5 feet on the morning of July 8. Previous flood heights recorded are, 15 feet April 

6, 1913, and 8.9Jeet April 12, 1916, both of which are known to have occurred during 

the spring break-up, and are supposed to have been chiefly the result of ice jams 

reported by the observer at these times. Therefore the discharge of July 3, 1919, is 

assumed to be the greatest on record.

Thief River enters Red Lake River at Thief River Falls, 50 miles above Crookston. 

A gaging station was maintained 4 miles above its mouth from 1909 to 1917, at which 

point the drainage area is 1,010 square miles. The extreme natural low stage at the 

station is 3.6 feet (discharge, about 1 second-foot). No daily records during the flood 

of 1919 were obtainable, but the stage of the river was found by a hydrographer, on 

the afternoon of July 8, to be at gage height 14.5 feet (discharge, 4,100 second-feet) 

and still rising slowly, but apparently near its maximum. From information obtained 

from the former gage reader, when the station was reestablished on April 1, 1920, it 

was ascertained that the river rose to a crest stage of about 16.3 feet (discharge, 4,900 

second-feet) on or about July 10.. A gage height of 14.5 feet, was reached on April 23, 

1916. On April 7,1913, the stage of the river rose to 14 feet, but this was caused in 

part by ice jams. No other recorded gage height approaches the height for July, 1919. 

The flood flow of Thief River was delayed at least four days, presumably in former 

lake basins, now drained, and hence reached the lower Red Lake River so long after 

the crest of the main flood that its damaging effect was practically negligible.

A station was. maintained from 1909 to 1918 on Red Lake River at Thief River Falls, 

below the entrance of Thief River; total drainage area, 3,430 square miles. The 

natural minimum stage there is 2.8 feet (discharge, 7 second-feet). Gage readings 

were obtained for several days during the flood of 1919. During the night of July 2 

there was an abrupt rise, to a gage height of 11.1 feet on the morning of July 3. On 

the morning of July 4 the gage height was 12.6 feet, the maximum, 12.7 feet (discharge, 

7,600 second-feet), occurring in the afternoon. On the morning of July 5 the stage 

was 12.5 feet, from which there was a gradual fall to 11.2 feet on the morning of July 8. 

The maximum stage recorded at this station is 15 feet April 16, 1916 (discharge, 

10,600 second-feet). No other heights above 10 feet have occurred at this station 

while it has been maintained, except on April 6,1916 (10.8 feet), and on April 10,1917 

(10.6 feet), both of which occurred during the spring break-up; hence the maximum 

discharge of the flood of July, 1919, was much greater than any other except that of 

April, 1916.

From the observed gage heights at Crookston for the week of highest stage, July 4 

to 10, inclusive, the total run-off for the seven days is found to be 145,000 acre-feet. 

This is, however, a total of only 0.5 inch per square mile of drainage area, which illue-
56 SURFACE WATEE SUPPLY, 1919^-1920, PART V.

trates how small a fraction of rainfall flows immediately off from level, undrained, or 

imperfectly drained swampy land such as this river flows through.

If it be assumed that the time of flow to Crookston from Red Lake Falls was about 

24 hours, and from Thief River Falls about 36 hours, the partial gage-height record at 

each of these points would indicate that about 55,000 acre-feet was contributed by 

Clearwater River, which is 0.8 inch per square mile of drainage area. About 80,000 

acre-feet reached Crookston from Thief River Falls during the week of highest stage, 

of which an estimated amount of 25,000 acre-feet was contributed by Thief River, 

although this estimate is doubtful on account of lack of continuous gage readings on 

Thief River. v

This flood caused no loss of life, although at Crookston much inconvenience and 

considerable injury resulted. It caused a very great loss to agricultural and grazing 

lands by overflow. The streams overflowed their banks at low places, submerging 

the crops long enough to cause total loss, and covering the vegetation in pasture lands 

with slime and mud so as to destroy all grazing that summer. However, the area 

injured by overflow from the rivers was very small as compared with that which suffered by the collecting of water on the lower fields from other fields a few inches or 

feet higher. On account of the small slope of the country and the infrequency of 

drainage ditches the water remained on the land several days, and destroyed its usefulness for that season.

THIEF RIVER NEAR THIEF RIVER FALLS, MINK.

LOCATION. In sec. 3, T. 154 N., R. 43 W., 1,000 feet above steel highway bridge, in 

Marshall County, 5 miles north of Thief River Falls, Pennington County, and 5 

miles above mouth of Thief River.

DRAINAGE AREA. 1,010 square miles.

RECORDS AVAILABLE. July 1,1909, to September 30,1917, and April 1 to September 

30, 1920.

GAGE. Chain gage installed August 19,1920, on cantilever timber fastened to a tree 

on right bank; read by Byron Yager. During p'eripd April 2 to August 18,1920, 

high stages prevented the installation of the chain gage and a series of temporary 

gages was used. An auxiliary staff gage is attached to left abutment of highway 

bridge, 1,000 feet below chain gage.

DISCHARGE MEASUREMENTS. Made from steel highway bridge 1,000 feet below gage 

or by wading near gage.

CHANNEL AND CONTROL. One channel at all stages. Bed composed of heavy gravel 

and boulders; practically permanent. Banks high and not subject to overflow.

EXTREMES OF DISCHARGE. Maximum discharge estimated, 1,780 second-feet April 

8 (stage-discharge relation affected by ice); minimum stage, 3.6 feet September 

10, 11, and 19-21 (discharge, 0.4 second-foot).

1909-1917; 1920: Maximum stage recorded, 14.5 feet April 23, 1916 (discharge, 

4,080 second-feet); practically no flow past the gage October 1, 1910, to March 

12,1911, August 2-13, 22-26,1911, September 1-3, 5-12,14-18,1911, and November 10, 1911, to March 26, 1912.

Flood of July, 1919, reached a stage of about 16.3 feet (discharge, about 4,900 

second-feet).

REGULATION. Dam at Thief River Falls, three-quarters of a mile below mouth of 

Thief River, backs up the water in Thief River for several miles, but the station 

is protected from influence of dam by rapids below.
HUDSON BAY DRAINAGE BASIN". 57

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

defined/ below 3,800 second-feet. Gage read to half-tenths once daily. Daily 

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

period April 1-9, when stage-discharge relation was affected by ice, for which it 

was ascertained by applying to rating table the daily gage height corrected for 

backwater from ice, and except for period April 25-26, for which it was interpolated on account of lack of gage readings. Open-water records excellent; winter 

records fair.

COOPERATION. Station maintained in cooperation with the Department of Drainage and Waters, E. V. Willard, commissioner.

PEMBINA RIVER AT NECHE, N. DAK,

LOCATION. At Great Northern Railway bridge a third of a mile above Great Northern 

Railway dam and two-thirds of a mile north of Neche, in Pembina County.

DRAINAGE AREA. 2,960 square miles (revised).

RECORDS AVAILABLE. May 1, 1903, to September 30, 1915, and April 1, 1919, to 

September 30, 1920.

GAGE. Vertical staff bolted to concrete abutment at north end of railway bridge; 

read by P. J. Horgan.

DISCHARGE MEASUREMENTS. Made from highway bridge 350 feet below railway 

bridge; at very low stages made by wading below Great Northern dam.

CHANNEL AND CONTROL. Bed composed of clay and silt. Control is loose-rock 

dam, a third of a mile below gage; shifts slightly.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 18.3 feet April 8 (stage-discharge relation affected by ice); maximum 

open-water stage, 15.1 feet April 15 (discharge, 2,430 second-feet); minimum 

discharge, estimated 4 second-feet April 1 and 2, because of ice.

Maximum discharge during year ending September 30, 1920, estimated 361 

second-feet April 19 and 20 (stage-discharge relation affected by ice); minimum 

stage recorded, 3.5 feet August 24 to September 20 (discharge, 10 second-feet).

1903-1915; 1919 and 1920: Maximum discharge recorded, 3,870 second-feet 

May 2, 1904 (gage height, 20.9 feet); a stage of 21.4 feet (discharge, 3, 850 secondfeet) was reached April 8, 1913; minimum stage recorded, 1.3 feet September 

15, 16, 18, 19, and 21-24, 1911 (discharge, 1.0 second-foot).

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. The water is raised at low stages from 1 to 2 feet at the gage by the 

loose rock dam about 3 feet high, a third of a mile below, constructed to give 

sufficient depth of water for the intake of Great Northern Railway water tank. 

There is considerable leakage through the dam, but no permanent determination 

of the effect of the dam can be made because it is liable to be somewhat disturbed 

at its crest,by ice run or spring floods in any year. There are no reservoirs or power 

plants that affect the flow.

ACCURACY. Stage-discharge relation changed slightly during winter of 1919-20. 

Rating curves used during periods April 1 to November 30, 1919, and March 26 

to September 30,1920, both well defined between 10 and 4,000 second-feet; curve 

used during the latter period is a revision below 425 second-feet of curve used 

during former period. Gage read to tenths once daily. Daily discharge ascertained by applying daily gage height to rating table except for periods indicated 

in footnote to tables of daily discharge. Open-water records good; winter records 

poor.

ROSEAU RIVER AT CARIBOU, MINN.

LOCATION. In sec. 34, T. 164 N., K. 45 W., at steel highway bridge in Caribou, Kittson County, 1 mile south of international boundary and 3 miles upstream from 

crossing of boundary line by river.

DRAINAGE AREA. 1,340 square miles.

RECORDS AVAILABLE. April 1 to October 6, 1917; April 12 to September 30, 1920.

GAGE. Chain gage fastened to downstream handrail of bridge, 60 feet from left abutment; read by James A. McKibbin.

DISCHARGE MEASUREMENTS. Made from highway bridge.

CHANNEL AND CONTROL. Channel is artificial, of trapezoidal cross-section, about 100 

feet wide and 10 feet deep. Bed composed of hardpan, with few scattered large 

boulders. Point of zero flow, bottom of channel, gage height about 3.0 feet.

EXTREMES OP DISCHARGE. Maximum stage recorded during period, 11.5 feet April 

15 (discharge, estimated 1,600 second-feet, because of ice); minimum stage, 3.15 

feet August 23 to September 1 and September 8-14 (discharge, 12 second-feet) 

1917 and 1920: Maximum stage recorded same as for 1920; minimum stage, 3.15 

feet September 10-12, 29, and 30, 1917 (discharge, about 4 second-feet).

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS . No diversions involving storage or loss of water. A small channel about 

3$ miles long was dredged some years ago from a point about 4 miles above the 

station to a point 1 mile below. At stage of about 6.0 feet water flows in this channel and must be measured and included in all measurements of the main channel.

REGULATION . None.

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

Rating curve, based on 7 discharge measurements and on computations using 

Kutter's formula, is fairly well defined throughout. Gage read to half-tenths 

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

table except for periods indicated in footnote to table of daily discharge. Records 

good.

COOPERATION. Station maintained in cooperation with the Department of Drainage 

and Waters, E. V. Willard, commissioner.

MOUSE BIVER AT MINOT, N. DAK.

LOCATION. At Anne Street footbridge, northeast of Great Northern Eailway roundhouse at Minot, in Ward County. 

DRAINAGE AREA. 8,400 square miles. 

EECORDS AVAILABLE. May 5,1903, to September 30,1920.
62 SURFACE WATER SUPPLY, 1919-1920, PART V.

GAGE. Temporary vertical staff gage on shore of river, 500 feet above Anne Street 

footbridge; installed by observer about April 1, 1919, when old Anne Street 

bridge was taken down and the staff gage on that bridge was destroyed; used 

October 1, 1918, to September 30, 1920. About March 10, 1920, a new vertical 

staff gage in two sections was installed on the piers of the new Anne Street bridge, 

but was read only once a week, the temporary gage being used through remainder 

of year. Gages read by Ephraim Cox. From 1903 until December, 1909, gage 

was a vertical staff located on a footbridge then existing about 20 rods above 

Anne Street. All gages referred to same datum.

DISCHARGE MEASUREMENTS. Made from Anne Street bridge, North Street bridge, 

South Sixth Street bridge, or by wading.

CHANNEL AND CONTROL. Bed composed of clay and silt; practically permanent. 

Control is timber and loose-rock dam 1 mile below gage at water tank of .Minneapolis, St. Paul & Sault Ste. Marie Railway. Dam is submerged at high stages, 

causing a reversal in the rating curve.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 15.0 feet April 18-20 (discharge, 1,860 second-feet); minimum stage, 

3.95 feet August 26-28 and September 1-3, 9, and 21-23 (discharge, 0.7 secondfoot).

Maximum stage recorded during year ending September 30,1920,17.1 feet May 

5 and 6 (discharge, 2,560 second-feet); minimum stage, 3.7 feet February 29 and 

March 6 (discharge, 0.4 second-foot).

1903-1920: Maximum stage recorded during period, 21.9 feet April 20, 1904 

(discharge, estimated 12,000 second-feet); minimum stage, 1.8 feet February 28, 

1913 (discharge, 0.1 second-foot).

ICE. Stage-discharge relation affected by ice.

^REGULATION. Dam about 5 feet high at Minneapolis, St. Paul & Sault Ste. Marie 

Railway tank, a mile below, raises water at gage about 5 feet at ordinary low stage. 

The dam being designed merely to give enough depth of water for the intake-pipe 

suction, has no sluices, but is not absolutely tight. When discharge is less than 

about 6 second-feet, the water level falls below crest of dam.

DIVERSIONS . None.

ACCURACY. Stage-discharge relation changed slightly during latter part of 1918; 

affected by ice during winters of 1919 and 1920; otherwise permanent. Two 

rating curves used, both well defined below 2,500 second-feet; applicable respectively, October 1 to November 30,1918, and December 1,1918, to September 

30, i920; curve used during latter period is a slight revision at the low-water end 

of curve used during former period. Gage read to half-tenths once daily during 

open-water periods, and to half-tenths once a week during ice-affected periods. 

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

for periods indicated in footnote to tables of daily discharge. Open-water records 

fair; winter records poor.

EVAPORATION AT UNIVERSITY, N. DAK.<

The evaporation gage at University, N. Dak., was established April 17, 1905, on a 

pool in a ravine called English Coulee, which runs through the campus of the University of North Dakota, immediately west of Grand Forks, N. Dak., and 2 miles west 

of the Minnesota boundary.

The coulee drains about 60 square miles of very level prairie. Except for brief 

freshets the flow in the coulee is small, varying from 1 second-foot or less to 20 secondfeet. In very dry weather the water lies in pools with scarcely any perceptible flow.

A heavy galvanized iron tank, 3 feet square and 18 inches deep, is placed in the 

center of an anchored raft, so that the water in the tank is at the same level as the 

water surface outside. The tank is filled nearly to the top, to a height precisely 

marked by the pointed tip of a vertical rod in the center of the tank. Once each 

day, after the change produced by evaporation or rainfall, the water level is restored 

to the original height, the precise amount of water transferred being measured with a 

cup of such size that one cupful of water is equivalent to 0.01 inch depth in the tank.

On the open prairie 40 rods distant is a standard rain gage. On days of rainfall the 

difference (which is usually small) between the quantity measured by the rain gage 

and the surplus in the tank is considered the evaporation for the day.

Observations were made usually about half an hour before sunset. The temperature of the water recorded is the temperature of the water in the tank. As the tank 

is made of metal, it has been found that at that time of day there is seldom a perceptible 

difference in temperature reading between the water within and without the tank. 

The temperature of the air as recorded is the mean of the readings of the standard 

self-recording maximum and the self-recording minimum thermometers for the 

preceding 24 hours.

The following table shows for each 10-day period during the years ending Septemjber 30,1919 and 1920, the gross evaporation, the total rainfall, and the mean temperatures for the 10 observations of the water and of the air.

< For complete description of this station and records of evaporation, rainfall, and temperature for 1905 

to 1908, see U. S. Geol. Survey Water-Supply Paper 245, pp. 64-67,1910.

NOTE. Station temporarily discontinued June 15,1920.

KAWISHIWI RIVER NEAR WINTON, MINN.

LOCATION. In sec. 20, T. 62 N., R. 11 W., in pond above lower dam of St. Croix 

Lumber Co. at Kawishiwi Falls, 500 feet above Fall Lake, 3,000 feet below 

Garden Lake, near west line of Lake County, and 2£ miles east of Winton, St. 

Louis County.

DRAINAGE AREA. 1,200 square miles.

RECORDS AVAILABLE. June 21,1905, to June 30, 1907; October 14,1912, to September 30, 1919, when station was discontinued.

GAGE. Stevens water-stage recorder installed the latter part of September, 1912, 

by the International Joint Commission in cooperation with the United States 

Geological Survey, at a point just above right end of dam. Well was attached 

to timbers, which were bolted to the vertical rock wall of right bank of river. 

Auxiliary staff gage was also attached to one of these timbers. The gage shelter 

was supported by timbers which were bolted to the horizontal portion of the rock 

wall above all possible high water. On May 27, 1913, the Stevens was replaced 

by a Friez water-stage recorder. During the high water of June, 1914, the well 

together with the float and weight were carried away by logs. At this time 

a concrete well was installed by the International Joint Commission a little 

below the dam and outside the river channel, and connected with pool above the 

dam by a pipe through the dam. The gage was repaired and again put in operation about July 1, 1914. Both water-stage recorders refer to the same datum. 

Attended by G. W. Byshe.

DISCHARGE MEASUREMENTS. Made from cable about 1,000 feet above gage.

CHANNEL AND CONTROL. At the gage the river flows through a small deep pool 

formed by a timber dam without openings, which constitutes the control of 

the gage, and is permanent unless dam is destroyed or alterations are made in the 

crest About 200 feet above dam is a decided fall. Banks high enough to 

prevent overflow in vicinity of gage. At measuring section bed of stream is composed of rock and boulders; rather rough. Current very swift except at low stages.
66 SURFACE WATER SUPPLY, 1919-1920, PART V.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.58 feet at 

11 a. m. April 30 (discharge, 2,500 second-feet); minimum stage, 0.35 foot September 22-30 (discharge, 30 second-feet).

1905-1907 and 1912-1919: Maximum stage recorded, 7.2 feet April 30 and 

May 7, 1916 (discharge, 5,370 second-feet); no flow, August 24, 25, 30, 31, and 

September 1, 1905, August 6 and 8, 1906, and April 23, 24, and 26, 1907; caused 

by regulation at outlet of Garden Lake.

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

REGTJIM.TION. St. Croix Lumbef Co. has a dam at outlet of Garden Lake for controlling the level of water in that lake, and for storing water to be used in driving 

logs over the stretch of rapids between Garden and Fall lakes. This dam is 

capable of holding the water in Garden Lake about 7 or 8 feet above its natural 

level at low water before water will flow over the gates. When the water in 

Garden Lake is held at a high stage, the elevation of water is considerably higher 

in Farm Lake, and it is understood that the elevation of the surface of White 

Iron Lake is somewhat affected by the stage of Garden Lake. During the log 

driving season, April to November, the water in Garden Lake is held to the 

elevation of top of gates practically all the time. In November some of the gates 

are opened so that the lake is drawn down to low-water stage, and remains so until 

spring. St. Croix Lumber Co. has a dam at outlet of Birch Lake, which controls 

its elevation, and is capable of holding the water about 5 feet above low water. 

This dam is left open during winter and until high water of the spring break-up 

has passed. It is than closed, and the lake held as high as possible during the summer. There are a number of low dams in Stony River used for sluicing logs off 

rapids, but these have no storage of importance back of them. Large volumes of 

water are allowed to pass through sluices of dam at outlet of Garden Lake for a 

few hours at a time, at irregular intervals, when desired to drive logs from Garden 

Lake to Fall Lake. At other times these gates are closed so that there is only a 

slight flow caused by leakage through dam. At other times some of the gates are 

partly opened to allow passage of sufficient water to prevent flow over crest of 

dam. During the year there was little log driving on rivers. 

ACCURACY. Stage-discharge relation permanent; not affected by ice or logs. Rating 

curve fairly well defined below 2,890 second-feet. Continuous gage record from 

recording gage during open-water period; weekly gage readings during winter. 

Daily discharge ascertained as follows: October 1 to 31 and April 23 to September 

30, obtained from water-stage recorder graph by means of discharge integrator; 

April 21 and 22 interpolated, on account of lack of gage readings; ten-day averages, 

November 1 to April 20, based on weekly gage readings. Records good for periods 

when water-stage recorder was operating; fair for other periods. Information 

as to operation of gates in dam at outlet of Garden Lake given in footnote to table 

of daily discharge.

No discharge measurements were made at this station during the year

UPFEB MISSISSIPPI BIVEB BASIN. 

MISSISSIPPI RIVER AT ELK RIVER, MINK.

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

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

DRAINAGE AREA. 14,500 square miles.

RECORDS AVAILABLE. July 22, 1915, to September 30, 1920.

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

read by Reynard Ebner.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

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

Banks high and not subject to overflow.

EXTREMES OK DISCHARGE. Maximum stage recorded during year ending September 

30,1919, 7.23 feet at 7.28 a. m. April 15 (discharge, 14,800 second-feet); minimum 

open-water stage recorded, 2.38 feet at 6.51 p. m. .October 15 (discharge, about 

1,890 second-feet); minimum discharge may have occurred during ice-affected 

period.

Maximum open-water stage recorded during year ending September 30, 1920, 

9.77 feet at 8 a. m. March 28 (discharge, 24,100 second-feet); minimum discharge, 

estimated 1,880 second-feet November 13 (stage-discharge relation affected by ice). 

1915-1920: Maximum open-water stage recorded during period, 10.8 feet April 

7, 1916 (discharge, 27,000 second-feet); maximum discharge probably occurred 

on or about April 5, 1917, and has been estimated at about 34,000 second-feet, 

from records of discharge at Coon Rapids power plant; minimum discharge 

estimated, 1,880 second-feet November 13, 1919 (stage-discharge relation affected 

by ice).

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. Nearest dam above station on the Mississippi is at St. Cloud, 40 miles 

upstream. An observed systematic diurnal fluctuation at gage of about 0.1 foot 

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

eliminated before reaching the 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.

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

curve well defined between 4,620 and 12,400 second-feet, and fairly well defined 

between 12,400 and 26,300 second-feet. Gage read to hundredths twice daily. 

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

except for periods indicated in footnote to tables of daily discharge. Open-water 

records excellent; winter records fair.

COOPERATION. Gage readings furnished by United States Engineer Corps.

MISSISSIPPI RIVER AT ST. PAUL, M1NN.

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

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

DRAINAGE ABBA. 35,700 square miles.

RECORDS AVAILABLE. March 22, 1887, to September 30, 1920. Observations of 

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

United States Weather Bureau. Many discharge measurements were made prior 

to 1900 by United States Engineer Corps.

GAGE. Chain gage installed May 9, 1913, on handrail, downstream side, of Chicago 

Great Western Railway bridge, near foot of Robert Street; read by United States 

Weather Bureau employees. From 1911 to May 9,1913, the gage was a vertical 

staff attached to a piling on left bank of river about 800 feet upstream from present 

gage. Prior to 1911 a vertical staff gage on Diamond Joe Line wharf, at foot of 

Jackson Street, about 400 feet below chain gage, was used. The datum of all 

three*gages is the same, allowance being made for the slight slope in river between 

them.
tTPPEB MISSISSIPPI BIVEE BASIK. 7i

EXTREMES ov DISCHARGE. Maximum stage recorded during year ending September 

30, 1918, 7.5 feet March 24 and 25 (discharge, 20,900 second-feet); minimum 

stage recorded, 1.0 foot September 30 (discharge, 2,630 second-feet).

Maximum stage recorded during year ending September 30, 1919, 13.8 feet 

April 22 (discharge, 54,500 second-feet); minimum stage recorded, 0.7 foot 

October 21 (discharge, 2,920 second-feet).

Maximum stage recorded during year ending September 30, 1920, 13.6 feet 

March 29 (discharge, 53,100 second-feet); minimum stage recorded, 0.4 foot 

November 14 (discharge, 4,220 second-feet).

1887-1920: Maximum stage recorded, 18.0 feet April 6,1897 (discharge, 80,800 

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

Highest known discharge occurred July 22, 1867, and amounted to 117,000 

second-feet.

DISCHARGE MEASUREMENTS. Up to 1915 made from Chicago, St. Paul, Minneapolis 

& Omaha Eailway bridge, 2 miles above station; in November, 1915, and April,

1916. measurements were made from Chicago Great. Western Railway bridge to 

which present gage is attached. Since 1916 measuftpftients have been made from 

Wabasha Street highway bridge, about 1,000 feet aodve station.

CHANNEL AND CONTROL. Channel somewhat shifting. Control not well defined. 

Banks moderately high; have not been overflowed in recent years.

ICE. Stage-discharge relation seriously affected by ice.

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

the nearest dam in Minneapolis may cause 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 changed between September 12 and October 9,

1917. owing to dredging of channel beginning at a point about a third of a mile 

below gage*and terminating 3,000 feet farther downstream. Since the dredging 

was completed stage-discharge relation has been practically permanent except as 

affected by ice. Two rating curves used during 1918,1919, and 1920; one, applicable October 1,1917, to September 30, 1919, is fairly well defined, the other, a 

revision of the 1918 and 1919 curve between 6,830 and 42,000 second-feet, and 

applicable October 1,1919, to September 30,1920, is well defined between 6,000 

and 48,000 second-feet. Gage read to tenths once daily. Daily-discharge ascertained by applying daily gage height to rating table except during periods of ice 

effect, December 7, 1917, to March 17, 1918, December 11,1918, to March 14, 

1919, and December 2,1919, to March 8,1920, for which no estimates of discharge 

were ma4e. Records fair.

74 SURFACE WATER SUPPLY, 1919-192Qj PABT V.

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, and 500 feet below mouth of Chippewa River.

DRAINAGE AREA. 6,300 square miles.

RECORDS AVAILABLE. July 22, 1909, to September 30, 1920.

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

Esther Hendricks. Datum of gage lowered 2 feet September 16,1909, and 1 foot 

more July 29, 1910, to avoid negative readings. All gage heights referred to 

latest datum.

DISCHARGE MEASUREMENTS. Made from upstream side of bridge.

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

permanent. There is a slight rapids just below gage, but the control section 

is not well defined. The banks are of medium height, and will be overflowed 

at a stage of about 14 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 30, 1919, about 18.85 feet June 25 (discharge, about 22,000 second-feet); 

gage height furnished by A. F. Meyer, consulting engineer, Minneapolis, Minn.; 

minimum open-water stage, 1.82 feet October 5 (discharge, about 52 second-feet). 

Maximum stage recorded during year ending September 30, 1920, 15.05 feet 

July 13 (discharge, 8,930 second-feet); minimum stage recorded, 3.06 feet October 1 and 12 and November 5 (discharge, 207 second-feet).

1909-1920: Maximum stage recorded, about 18.85 feet June 25,1919 (discharge, 

about 22,000 second-feet); minimum discharge recorded, 6.8 second-feet February 9,1912, by current-meter measurement.

ICE. Stage-discharge relation seriously affected by ice.

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

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

slight fluctuation in stage of Minnesota River at gage.

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

ice December 21, 1918, to March 16, 1919, and November 24, 1919, to March 16, 

1920. One rating curve used; fairly well denned. Gage read to hundredths 

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

table except during periods of ice effect for which no discharge computations 

were made, and except for period June 23 to July 3,1919, when gage was not read 

because of flooded banks, for which period daily discharge was ascertained from 

field investigations and studies by Adolph F. Meyer, consulting engineer, 

Minneapolis, Minn. Records good for 1919; fair for 1920.

MINNESOTA RIVER NEAR MANKATO, MJNN.

LOCATION. In sec. 14, T. 108 N., E. 27 W., at Sibley Park, 2 miles above center of

Mankato, Blue Earth County, and 1,000 feet below mouth of Blue Earth River. 

DRAINAGE AREA. 14,600 square miles. 

RECORDS AVAILABLE. May 20, 1903, to September 30, 1920. 

GAGE. Chain gage on right bank of river, about 1,000 feet below mouth of Blue

Earth River; read by Clarence Staley, observer for United States Weather Bureau.

The gage support is a fairly .substantial cantilever structure, supported by two

heavy posts resting in concrete footings; settling somewhat; constructed and

maintained by the U. S. Engineer Corps. 

DISCHARGE MEASUREMENTS. Made from new concrete highway bridge in center

of Mankato 2 miles below gage, by wading a short distance below gage, or at

extreme high stages, by boat near gage. 

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

stages. Banks moderately high and not subject to overflow, except at stages

above gage height of 15 feet. Control not well denned. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September

30, 1918, 10.9 feet August 24 (discharge, 14,500 second-feet); minimum stage

recorded, 1.2 feet October 10, 11, 15-17, 25, 26, 31, November 1-3, 11-14, 20-24,

and December 4-10 (discharge, 420 second-feet). 

Maximum stage recorded during year ending September 30, 1919, 18.9 feet

June 21 (discharge, 35,800 second-feet); minimum stage recorded, 1.2 feet October

23-28 (discharge, 720 second-feet). 

Maximum stage recorded during year ending September 30, 1920, 12.0 feet

July 18 (discharge, 19,600 second-feet); minimum stage recorded, 1.2 feet October

22, 25, and 26 (discharge, 660 second-feet). 

1903-1920: Maximum stage recorded, 21.2 feet June 26, 1908. (discharge, 43,800

second-feet); minimum stage recorded, 0.5 foot August 31 to September 2,1911

(discharge, 89 second-feet). 

The highest known stage of this river occurred in 1881, and is shown in Mankato

by a well-marked line, about 27 feet above zero of present gage (discharge, estimated 65,000 second-feet).
UPPER MISSISSIPPI EIVEB BASIN. 77

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. The nearest dam on Minnesota River is at Minnesota Falls, 140 milea 

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

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

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

times to over 1 foot.

ACCURACY. Stage-discharge relation not permanent; affected by ice January 1 to 

March 18, 1918, December 11, 1918, to March 13, 1919, and December 5, 1919, 

to March 22, 1920. Two rating curves used, one from October 1, 1917, to March 

19,1918, and one from March 20,1918, to September 30,1920; both curves poorly 

defined. Gage read to tenths once daily. This gage reading does not represent 

accurately the mean daily stage on account of fluctuation caused by artificial 

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

table except for periods when stage-discharge relation was affected by ice for 

which no computations of discharge were made. Indirect method for shifting 

control used October 1, 1919, to September 30, 1920. Records probably poor.

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

Discharge measurements of Minnesota River near Mankato, Minn., during the years ending

Sept. SO, 1919 and 1920.

ST. CROIX RIVER AT SWISS, WIS. '

LOCATION. In sec. 33, T. 42 N., R. 15 W., at highway bridge near post office of Swiss, 

Burnett County, 2 miles above point where St. Croix River becomes boundary 

line between Wisconsin and Minnesota, and 10 miles northeast of Dan bury, 

Minn., on Minneapolis, St. Paul & Sault Ste. Marie Railway. Namakagon River 

enters from left 3| miles above station.

DRAINAGE AREA. 1,550 square miles (measured on map issued by Wisconsin Geological and Natural History Survey, edition of 1911: scale, 1 inch=6 miles).

RECORDS AVAILABLE. March 13, 1914, to September 30, 1920.

GAGE. Chain gage attached to downstream side of bridge May 16.1918; read by Capt. 

Richard Goldschmidt. Prior to that date a cast-iron staff gage bolted to concrete 

pier at left end of bridge was used. Both gages at same datum.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Bed composed of gravel; smooth. Growth of aquatic 

plants during summer may cause a small amount of backwater at gage. Left 

bank high and not subject to overflow; right bank of medium height and may possibly be overflowed during extremely high water.
80 SUKFACE WATER SUPPLY, 1919-1920, PAET V.

EXTREMES OF DISCHARGE. Maximum discharge recorded during year ending 

September 30, 1919, 3,330 second-feet April 11; minimum discharge, estimated 

740 second-feet February 2 (stage-discharge relation affected by ice).

Maximum discharge recorded during year ending September 30, 1920, 6,300 

second-feet at 6.30 p. m. July 2 (gage height, 5.55 feet); minimum discharge, 

estimated 710 second-feet January 23 (stage-discharge relation affected by ice).

1914-1920: Maximum stage recorded, 6.73 feet April 22, 1916 (discharge, 8,480 

second-feet); minimum discharge, estimated 700 second-feet February 2 and 6, 

. 1918 (stage-discharge relation affected by ice). 

ACCURACY. Stage-discharge relation not permanent; affected by ice December 1,

1918. to March 25, 1919, and November 28, 1919, to March 26, 1920. Two fairly 

well defined rating curves used; one applicable October 1, 1918, to March 25,

1919. and March 27 to September 30, 1920, and the other applicable March 26, 

1919, to March 26, 1920. Gage read to quarter-tenths twice daily. Daily discharge ascertained by applying mean daily gage height to rating table except 

for periods of ice effect for which it was ascertained by means of gage heights, 

discharge measurements, observer's notes,and weather records. Open-water 

records good; winter records fair.

UPPEE MISSISSIPPI BIVEB BASIN. 85

NAMAKAGON RIVER AT TREGO, WIS.

LOCATION. In sec. 35, T. 40 N., R. 12 W., at Chicago, St. Paul, Minneapolis & Omaha 

Railway bridge at Trego, Waehburn County, 20 miles above confluence of Namakagon and Totogatic rivers.

DRAINAGE AREA. 420 square miles (measured on map issued by Wisconsin Geological 

and Natural History Survey, edition of 1911; scale, 1 inch=6 miles).

RECORDS AVAILABLE. March 11, 1914, to September 30, 1920.

GAGE. Enameled staff fastened to retaining wall, left bank of river, just above railroad bridge; read by Patrick Lawton.

DISCHARGE MEASUREMENTS. Made from lower chords of railroad bridge or by wading.

CHANNEL AND CONTROL. Bed composed of coarse gravel; free from vegetation; practically permanent. Banks medium high and not subject to overflow. Small 

island downstream with rapids on either side forms the control.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 2.3 feet at 7.55 a. m. March 21 and 7.45 a. m. April 13 (discharge, 803 

second-feet); minimum discharge, estimated 265 second-feet March 7-12.

Maximum stage recorded during year ending September 30, 1920, 3.25 feet 

June 30 (discharge, 1,530 second-feet); minimum discharge, 317 second-feet January 

8, by current-meter measurement.

1914-1920: Maximum stage recorded, 3.25 feet June 30, 1920 (discharge, 1,530 

second-feet); minimum discharge, estimated 235 second-feet December 19,1916 

(stagerdischarge relation affected by ice).

ICE. Stage-discharge relation seriously affected by ice.

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

24,1918, to March 18,1919, and November 28,1919, to March 23,1920. One rating 

curve used; well defined between 330 and 1,330 second-feet. Gage read to quartertenths once daily, except during ice-affected periods when it was read every other 

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

except for periods during which stage-discharge relation was affected by ice, for 

which it was ascertained by means of gage heights, discharge measurements, 

observer's notes, and weather records, and except for days during open-water 

periods when gage was not read, for which it was interpolated. Open-water 

records excellent; winter records fair.

APPLE RIVER NEAR SOMERSET, WIS.

LOCATION. In sec. 21, T. 31 N., R. 19 W., at power plant of St. Croix Power Co., 2 

milea above mouth of river and 3£ miles below Somerset, St. Croix County.

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

and Natural History Survey, edition of 1911; scale, 1 inch = 6 miles).

RECORDS AVAILABLE. January, 1901, to September 30, 1920.

GAGE. Vertical staff gage; readings not used in determination of flow.

DISCHARGE. The discharge of the turbines in second-feet corresponding to the number of kilowatts is determined for each hour during day from a record of the number 

of wheels in operation and the load; the sum of these figures divided by 24 gives 

the average^discharge through the turbines. To this quantity is added the leakage 

through the average number of wheels idle each day, the sum giving 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 the flow 

through plant. There is a constant leakage through the gate and flashboards 

amounting to 3 second-feet. This quantity has not been taken into consideration 

in computing the records.

EXTREMES OP DISCHARGE. Maximum discharge recorded during year ending September 30, 1919, 1,120 second-feet April 12; minimum discharge, 90 second-feet 

January 26 and July 6.

Maximum discharge recorded during year ending September 30, 1920, 1,370 

second-feet March 26; minimum discharge, 110 second-feet August 19.

1904-1920: Maximum discharge recorded, 2,280 second-feet in June, 1905; 

minimum discharge, 38 second-feet May 10, 1910. Owing to regulation the 

minimum discharge has no bearing on the natural minimum flow. No records of 

maximum and minimum stages are available for the period 1901 to 1903.
UPPER MISSISSIPPI RIVER BASIH. 89

REGULATION. There are a number of power plants above the station, but their pondage is small, and though the daily flow may be controlled to some extent, the 

mean monthly flow probably corresponds closely to the natural flow.

ACCURACY. Prom 1901 to 1909 the discharge through the plant was determined from 

tables computed from data collected at tests on one of the turbines made at flume 

of Holyoke Water Power Co., Holyoke, Mass. In the summer of 1909 engineers 

of St. Croix Power Co. made tests on- the water flowing through all the wheels as 

actually installed, by means of a sharp-crested weir 710 inches long located about 

60 feet below power house. These tests gave results about 3 per cent larger than 

the Holyoke tests, and tables based on them have been used in determining the 

discharge through the plant from 1909 to date. In May, 1914, a series of currentmeter measurements were made by the Wisconsin Railroad Commission and 

United States Geological Survey, and a rating curve for the tailrace was developed. 

Twelve tests were then run with different wheels and loads. It was found that 

the discharge as determined by the current meter and the discharge as computed 

by the company agreed very closely, the percentage difference for the twelve 

tests ranging from 6.4 per cent to +1.8 per cent, with an average of 2.0 per 

cent; the discharge as determined by the company being 2 per cent less than that 

determined by current meter. During 1919 three current-meter measurements 

were made to check the accuracy, under present conditions, of the data obtained 

in June, 1914. These measurements showed that power-plant records were about 

. 5 per cent less than the measured discharge, due probably to increased leakage 

through the wheels. The records published below are the power-plant records 

increased by 5 per cent.

COOPERATION. Records furnished by St. Paul Gas Light Co., of St. Paul, Minn., D. W. 

Flowers, engineer.

No discharge measurements were made at this station during year ending September 30, 1920.

NOTE. Daily discharge, 1902 to 1914, not available. 

105708 28 7
92 SURFACE WATER SUPPLY, 1919-1980, PART V.

KDTNIKINNIC RIVER NEAR RIVER FALLS, WIS.

LOCATION. In sec. 18, T. 27, N., R. 19 W., at Clifton Hollow bridge, a quarter of a 

mile downstream from dam of Clifton Palls Power Co., 2 miles above mouth of 

river and 7 miles downstream from River Falls, Pierce County.

DRAINAGE AREA. 170 square miles (measured on map issued by Wisconsin Geological and Natural History Survey, edition of 1911; scale, 1 inch=6 miles).

RECORDS AVAILABLE. October 23, 1916, to September 30, 1920.

GAGE. Gurley water-stage recorder, with a wooden well and shelter fastened to 

downstream side of right-hand cushing bridge pier.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of rather heavy gravel and sand. Control 

ia head of small rapids 150 feet below gage; shifting.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 7.0 feet at 4 p. m. March 12 (discharge, about 3,560 second-feet); minimum stage, between 1.7 and 1.8 feet (discharge, about 15 second-feet); occurred 

several times following complete shutdown of power plant. The maximum 

stage is about normal, but the minimum stage is affected by regulation at 

power house.

Maximum stage during year ending September 30,1920, not known, on account 

of nonoperation of water-stage recorder; minimum stage recorded, 1.62 feet at 

5 a. m. August 30 (discharge, 11 second-feet).

1917-1920: Maximum stage recorded, 7.0 feet March 12,1919 (discharge, about 

3,560 second-feet); minimum stage, 1.62 feet at 5 a. m. August 30,1920 (discharge, 

11 second-feet).

ICE. Stage-discharge relation affected to some extent by ice.

REGULATION. Daily flow is regulated almost completely by Clifton Palls Power Co.'s 

dam just above station. There are three dams in River Palls, operations at which 

may also have some effect on the daily flow, but the storage at these dams is relatively small, and the monthly flow ia considered to be nearly the normal flow.

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

Owing to shifting control, discharge measurements made during 1919 and 1920 

do not define a smooth curve, and therefore a curve was drawn which averages 

the measurements; used October 1, 1918, to September 30, 1920; poorly defined 

throughout. Continuous gage-height record obtained by recording gage except 

during winter and certain other brief periods noted in footnote to tables of daily 

discharge. Daily discharge ascertained by use of discharge integrator except 

for periods indicated in footnote to tables of daily discharge. Records poor.

Railway bridge 1 mile east of Bruce, Rusk County. Thornapple River enters 

from left immediately above station and Flambeau River from left about 21 

miles below.

DRAINAGE AREA. 1,600 square miles (measured on map issued by Wisconsin Geo- 

, logical and Natural History Survey, edition of 1911; scale, 1 inch=6 miles).

RECORDS AVAILABLB, December 31, 1913, to September 30, 1920.

GAGE. Chain gage, attached to downstream side of Minneapolis, St. Paul & Sault Ste. 

MarielRailway bridge; read by H. C. Gardner.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Bed composed of sand and small gravel; free from vegetation; first and second channels from the west fairly permanent; third channel 

nearest east bank has a tendency to fill during low stages with sand worked in 

by Thornapple River. Flow, except during extreme high stages, is confined 

within the banks.

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

September 30,1919, 9.1 feet at 6 p. m. April 11 (discharge, 8,320 second-feet); 

minimum discharge, 460 second-feet February 11 (determined by current-meter 

measurement).

Maximum open-water stage recorded during year ending September 30, 1920, 

12.5 feet at 6j>. m. March 27 (discharge, 13,800 second-feet); minimum discharge, 

estimated 480 second-feet January 5 (stage-discharge relation affected by ice).

1914-1920: Maximum open-water stage recorded, 12.5 feet March 27, 1920 

(discharge, 13,800 second-feet); minimum stage, 1.15 feet, morning and afternoon 

reading, August 21,1918 (discharge, about 260 second-feet); caused by regulation.
SUEFACE WATER SUPPLY, 191£-19S», PAET V.

REGULATION. Flow regulated to some extent by reservoir on West Fork of Cbippewa 

River, in sec. 14, T. 41 N., R. 6 W. Reservoir has a capacity of 550 million cubic 

feet, and is used in connection with reservoirs on Upper Flambeau River, for 

purpose of regulating the flow of Chippewa River. No diurnal fluctuation is 

observed.

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

low stages and by ice during periods December 1, 1918, to March 24, 1919, and 

November 29, 1919, to March 26,1920. Gage read to quarter-tenths twice daily. 

Two rating curves, both fairly well defined, used during 1919 and 1920, applicable 

respectively, October 1, 1918, to September 30, 1919, and October 1, 1919, to 

September 30, 1920. Daily discharge ascertained by applying mean daily gage 

height to rating table except for periods during which stage-discharge relation 

was affected by ice, for which it was ascertained by means of gage heights, discharge measurements, observer's notes> and weather records, and except for 

periods March 25 to September 30, 1919, and July 1 to September 30, 1920, for 

which it was ascertained by the indirect method for shifting control. Openwater records fair; winter records subject to error.

CHIPP.EWA RIVER AT CHIPPEWA FALLS, W3S.

LOCATION. In SE. £ sec. 6, T. 28 N., R. 8 W., at highway bridge at Ohdppewa Falla, 

Chippewa County, 2,500 feet below mouth of Duncan Creek, which comes in 

from right.

DRAINAGE AREA. 5,600 square miles.

BECORDS AVAILABLE. June 22, 1888, to September 30, 1920. The station was originally established by Chippewa Lumber & Boom Co., which has kept a continuous 

record since 1889. Since 1904 United States Weather Bureau has obtained gage 

readings during the flood season of each year. On June 1,1906, the United States 

Geological Survey began making measurements and obtaining gage readings.

CTAGE. On July 27, 1916, a Gurley water-stage recorder was installed in place of a 

Friez water-stage recorder which had been in operation since January, 1914, on 

web between cushing. piers supporting first right-hand span, about 10 feet upstream from gage formerly used by United^ States Weather Bureau; gage referred 

to original datum.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

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

banks high and are seldom overflowed.
TJPPEB MISSISSIPPI RIVJ3K BASIN. 101

EXTREMES OP DISCHARGE. Maximum stage during year ending September 30, 1919, 

is not known, but probably occurred during period April 13-18, the discharge 

amounting to about 45,000 second-feet; minimum stage recorded, about 0.10 foot 

at 2 p. m. September 14 (discharge, 680 second-feet); caused by regulation at 

Wissota dam.

Maximum stage recorded during year ending September 30, 1920, 17.0 feet 

about 1 p. m. March 27 (discharge, 78,000 second-feet),; minimum stage, -0.15 

foot at 6 p. m. January 25 (discharge, estimated 374 second-feet); caused by 

regulation at Wissota dam.

1888-1920: Maximum stage recorded, 26.03 feet December 6, 1896 (discharge 

not determined on account of effect of ice jam); minimum discharge recorded, 

about 40 second-feet February 4, 1917 (caused by regulation at Wissota dam). 

A stage of 26.94 feet was reached September 10,1884; discharge not determined.

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. Flow past station controlled to considerable extent by operation of 

the gates at the Wissota power plant of Wisconsin, Minnesota Light & Power" 

Co., a short distance above gage. Large diurnal fluctuation.

ACCURACY. Stage-discharge relation changed during flood of latter part of March, 

1920; affected by ice December 29, 1918, January 1-10 and February 5-8, 1919, 

and December 11, 1919, to March 24, 1920. Rating curve used during 1919 and 

1920, prior to flood of March, 1920, well denned between 530 and 56,200 secondfeet; poorly defined below 530 second-feet. Discharge measurements made after 

the March flood indicate that the control had lowered 0.1 foot and a rating curve 

parallel to and 0.1 foot lower than the 1919 curve has been used since the March 

flood. Continuous gage-height record obtained from water-stage recorder except 

for periods noted in footnote to tables of daily discharge. Daily discharge ascertained by means of discharge integrator, except as indicated in footnote to tables 

of daily discharge. Open-water records for periods when water-stage recorder 

was operating, good; other,records fair.

104 SURFACE WATER SUPPLY, 1919-1920, PART V.

FLAMBEAU RIVER NEAR BUTTERNUT, W1S.

LOCATION. In NW. i SE. isec. 33, T. 41 N., R. 1 E., 6 miles southeast of Butternut, 

Ashland County, and 7 miles upstream from Park Falls.

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

and Natural History Survey, edition of 1911; scale, 1 inch=6 miles).

RECORDS AVAILABLE. July 30, 1914, to September 30, 1920.

GAGE. Chain gage supported by built-up cantilever, attached to posts set in right 

bank of river; installed May 26, 1916; read by Mrs. Samuel Holt, jr. Vertical 

staff gage at same site and datum was used from July 30, 1914, until taken out by 

ice in spring of 1916.

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

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

low and subject to overflow; right bank slopes back gradually to high-water 

mark. At cable site, 1,500 feet below gage, the bed is rocky and banks high. 

Control is at head of Schultz Rapids, 200 feet below cable and 1,700 feet below gage.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 6.2 feet at 9 a. m. July 7 (discharge, 2,840 second-feet); minimum 

stage recorded, 1.45 feet at 7 a. m. and 6 p. m. October 26 (discharge, 316 secondfeet).

Maximum stage recorded during year ending September 30, 1920, 6.38 feet 

June 12 (discharge, 3,000 second-feet); minimum stage recorded, 0.90 foot 

August 27 and 28 (discharge, 204 second-feet).

1914-1920: Maximum stage recorded, 9.0 feet April 22 and 23, 1916 (discharge, 

5,430 second-feet); minimum stage recorded, 0.90 foot August 27 and 28, 1920 

(discharge, 204 second-feet).

Lake, in sec. 9, T. 42 N., R. 5 E., with an allowable capacity of about 1$ billion 

cubic feet, is the largest.

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

2,0, 1918, to April 1, 1919, and December 14,1919, to March 26,1920. One rating 

curve used; well denned between 356 and 3,480 second-feet. Gage read to 

quarter-ttenths.twice daily during open-water period; and every tttfcuer &&%.'. during 

winter period. Daily discharge ascertained by applying mean daily gage height 

to rating table, except for periods during which stage-discharge relation was affected 

by ice, for which it was ascertained by means of gage heights, discharge measurements, observer's notes, and weather records, and except for days when 

gage was not read, for which it was interpolated. Open-water records good;>, 

winter records fair.

CHANNEL AND CONTROL. Bed composed of gravel and sand; free from vegetation; practically permanent. At gage section, channel is divided by a small sandy island; at 

cable section the river flows in one channel. Banks are medium high, wooded, and 

not subject to overflow. Control not well denned; formed by channel below gage.

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

September 30,1919,7.3 feet April 12 (discharge, 9,800 second-feet); minimum discharge, estimated 650 second-feet March 5 (stage-discharge relation affected by ice). 

Maximum discharge during year ending September 30, 1920, estimated 12,000 

second-feet, March 31; minimum stage recorded, 1.40 feet August 28-30, and 

September 7-9 (discharge, 500'second-feet).

1903-1906 and 1914-1920: Maximum discharge recorded, 17,400 second-feet 

April 23,1916; minimum discharge, 390 second-feet December 4,1904.

ICE. Stage-discharge relation seriously affected by large quantities of frazil ice which 

form on the falls and rapids above station and fill the channel for a distance of 

several miles from the gage to pond of paper company's dam at Ladysmith.

REGULATION. Chippewa & Flambeau Improvement Co. operates storage reservoirs 

on Rest Lake and smaller reservoirs on Manitowish and Turtle rivers and Bear 

Creek. These reservoirs have an effective capacity of 1.15 billion cubic feet. 

Weekly fluctuations at gage are caused by operation of power plants at Park 

Falls and storage reservoirs. No daily fluctuation has been observed.

ACCURACY. Stage-discharge relation changed during flood of latter part of March, 

1920; affected by ice November 24, 1918, to March 29, 1919, and November 13, 

1919, to March 28, 1920; affected by logs at times. One rating curve used; well 

defined between 770 and 17,000 second-feet, extended beyond these limits; this 

rating curve was used direct during periods October 1,1918, to November 12,1919, 

and June Ljto September 30,1920; indirect method for shifting control used April 

24 to May §1,1920. Gage read to quarter-tenths once daily except during winter 

and during periods April 23 to August 10,1920, when it was read every other day, 

and March 28 to April 22, 1920, when no gage readings were obtained on account 

of gage having been destroyed by flood of March 28. Daily discharge ascertained 

by applying daily gage height to rating table except as indicated in footnote to 

tables of daily discharge. Open-water records excellent prior to flood of March, 

1920, and fair subsequent to that time; winter records fair.

UPPEE MISSISSIPPI RIVER BASIN.

EAU CLAIRE RIVER NEAR AUGUSTA, WIS.

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

Augusta, Eau Claire County. South Fork of Eau Claire River enters from left 

4 miles above station.

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

and Natural History Survey, edition of 1911; scale, 1 inch=6 miles).

RECORDS AVAILABLE. July 16, 1914, to September 30, 1920.

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

Howe.

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

control about 500 feet downstream from bridge. *

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

short distance below gage the channel narrows and a rock outcrop overlain with 

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

Point of zero flow, September 28, 1920, gage height, -0.9 foot .± 0.1 foot.

ICE. Stage-discharge relation seriously affected by ice.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 8.95 feet June 25 (discharge, 5,520 second-feet); minimum discharge, 44 

second-feet February 7 (determined by current-meter measurement).

Maximum stage recorded during year ending September 30, 1920, 11.98 feet at 

9 a. m. March 27 (discharge, 8,720 second-feet); minimum stage recorded, 0.00 

foot September 29 and 30 (discharge, 46 second-feet).

1914-1920: Maximum open-water stage recorded, 11.98 feet March 27, 1920 

(discharge, 8,720 second-feet); minimum discharge, estimated 3.5 second-feet, 

January 27,1918, from discharge measurement made through complete ice cover.

ACCURACY. Stage-discharge relation changed during high water of March, 1920; 

affected by ice November 30, 1918, to March 19,1919, and November 27, 1919, to 

March 22, 1920. Rating curve used during 1919 and 1920 prior to March 22,1920, 

well defined throughout; curve used March 23 to September 30,1920, well defined 

below 275 second-feet and is same as previous curve above 2,010 second-feet. 

Gage read to quarter-tenths once daily except during winter when it was usually 

read twice a week. Daily discharge ascertained by applying daily gage height to 

rating table, except for periods indicated in footnote to tables of daily discharge. 

Open-water records, good; winter records poor for 1919, and fair for 1920.

1920; mean discharge during former period and daily discharge during latter period, ascertained by means 

of gage heights, discharge measurements, observer's notes, and weather records. Discharge interpolated, 

Apr. 2-4,1919, and June 15 and 16,1920, on account of lack of gage readings. Braced figures show mean discharge for periods indicated.

116 SURFACE WATER SUPPLY, 1919-19*20, PART V.

RED CEDAR RIVER NEAR COLFAX, WIS.

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

Dunn County. Hay River enters from right about 11 miles below station and 

Trout Creek, also from right, 3J miles above.

DRAINAGE AREA. 1,100 square miles (measured on map issued by Wisconsin Geological and Natural History Survey, edition of 1911; scale 1 inch=6 miles).

RECORDS AVAILABLE. March 19, 1914, to September 30, 1920.

GAGE. Chain gage attached to downstream side of bridge; read by Andrew Lundeguam.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge, to which gage 

is attached.

CHANNEL AND CONTROL. Bedcomposedof rock and gravel; small amount of grass growth 

during summer. Control not well defined. Left bank high and not subj ect to overflow; right bank medium high and may be overflowed during extreme high water.

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

September 30, 1919, 5.0 feet at 6 p. m. March 18 (discharge, 4,450 second-feet); 

minimum discharge, estimated 405 second-feet February 1-10 (stage-discharge 

relation affected by ice).

Maximum stage recorded during year ending September 30, 1920, 6.95 feet at 

8 a. m. March 26 (discharge, 7,610 second-feet); minimum discharge, estimated 

490 second-feet February 25 (stage-discharge relation affected by ice).

1914-1920: Maximum stage recorded, 6.95 feet March 26, 1920 (discharge, 

7,610 second-feet); minimum discharge recorded, 368 second-feet February 19, 

1918 (by current-meter measurement through complete ice cover).

REGULATION. 5 The following dams and reservoirs are used to regulate the flow of Red

' Cedar River. Owing to operationof these reservoirs, the flow at station is not natural.

a Revised figures based in part on more accurate determinations from recent surveys and in. part on 

the limiting ofthe allowable range of stage in the reservoirs by decisions of the Railroad Commission of 

Wisconsin-. Storage in Chetek Lake is used for regulating flow to the power plant at the outlet.

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

growth of aquatic grass from May to September. One curve used; well defined 

between 653 and 4,450 second-feet; extended beyond these limits and may be 

in error. Gage read to quarter-tenths twice daily except during winter, when it 

was read every other day. Daily discharge ascertained by applying daily gage 

height to rating table except as indicated in footnote to tables of daily discharge. 

Open-water records fair; winter records subject to considerable error.

UPPER MISSISSIPPI RIVER BASIN. 119

RED CEDAR RIVER AT CEDAR FALLS, WIS.

LOCATION. In sec. 6, T. 28 N., R. 12 W., at highway bridge near Cedar Falls, Dunn 

County, 4J miles above crossing of Chicago, St. Paul, Minneapolis & Omaha 

Railway.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 1, 1909, to September 30, 1920.

GAGE. Staff gage fastened to bridge pier; read by John G. Wood.

DISCHARGE MEASUREMENTS. No discharge measurements have been made at this 

station, which is maintained to determine fluctuation in stage.

CHANNEL AND CONTROL. Channel rough and rocky, straight, and free from vegetation. Banks high and not subject to overflow.

EXTREMES OF STAGE. Maximum stage recorded during year ending September 30, 

1919, 5.15 feet at 5 p. m. April 12; minimum stage, 0.75 foot September 21 and 28. 

Maximum stage recorded during year ending September 30, 1920, 7.2 feet 

March 25 and 26; minimum stage, 0.75 foot October 5, 19, 26, November 9, December 7, January 11, 18, February 1, 8, March 7, May 9, August 15, 22, and September 19 and 26.

1909-1920: Maximum stage recorded, 7.2 feet March 25 and 26, 1920; minimum 

stage, 0.0 foot March 11, 1917. Minimum stages are caused by closing gates and 

wheels at power plant above station.

HEGULATION. Operation of storage reservoirs in the headwaters of the river (see 

"Regulation" in station description for Red Cedar River near Colfax, Wis.), 

together with storage at power plant above gaging station, regulates the flow.

ACCURACY. No discharge measurements have been made but stage-discharge relation believed permanent. Gage read to half-tenths twice daily during 1919, and 

once daily during 1920. Considerable diurnal fluctuation is observed, so that 

mean daily gage height does not represent the average stage.

COOPERATION. Ga^e-height record furnished by Wisconsin & Minnesota Light & 

i Power Co.

Daily gage height, in feet, of Red Cedar River at Cedar Falls, Wis., for the years ending

Sept. SO, 1919 and 1920.

RED CEDAR RIVER AT MENOMONIE, WIS.

LOCATION. In sec. 21, T. 28 N., R. 13 W., 900 feet below power house of Wisconsin 

& Minnesota Light & Power Co., Menomonie, Dunn County, and 13 miles above 

confluence of Red Cedar and Chippewa rivers. Wilson Creek discharges from right 

into service reservoir just above station.

DRAINAGE AREA. 1,810 square miles, (measured on map issued by Wisconsin Geological and Natural History Survey, edition of 1911; scale, 1 inch=6 miles).

RECORDS AVAILABLE. June 17,1907, to September 3,1908; May 9,1913, to September 

30,1920.

GAGE. Barrett & Lawrence water-stage recorder with a wooden well and shelter; 

installed May 9, 1913, on right bank of river, 1 mile above site of old gage, which 

was attached to a highway bridge about 200 rods west of Chicago & Northwestern 

Railway station west of Menomonie; read from June 17, 1907, to September 3, 

1908. No relation between datums of the two gages. Gage inspected by E. 

Kausrud.

DISCHARGE MEASUREMENTS. Made from highway bridge 1 mile below gage.

CHANNEL AND CONTROL. Bed at gage composed of heavy gravel; bed at measuring 

section sandy and subject to shift. Left bank at gage high and not subject to 

overflow; right bank of medium height and is overflowed at flood stages; both banks 

high at measuring section and not subject to overflow.
UPPER MISSISSIPPI RIVER BASIN. 121

EXTREMES OF DISCHARGE. Maximum discharge during year ending September 30, 

1919, estimated 6,000 second-feet March 17 (water-stage recorder not operating 

satisfactorily); minimum stage, 2.02 feet at noon October 13 (discharge, 444 secondfeet).

Maximum discharge during year ending September 30, 1920, estimated 14,000 

second-feet March 26 (maximum gage height was about 8.0 feet; water-stage 

recorder not operating satisfactorily); minimum stage recorded, 1.90 feet at 6 p. m. 

September 26 and 5 p. m. September 27 (discharge, 330 second-feet).

1907-8 and 1913-1920: Maximum discharge, estimated 14,000 second-feet 

March 26,1920 (maximum gage height was about 8.0 feet; water-stage recorder 

not operating satisfactorily); minimum stage recorded, 0.50 foot November 8, 

1907 (discharge, 100 second-feet).

REGULATION. Considerable diurnal fluctuation in stage at gage is caused by operation of power plants of Wisconsin & Minnesota Light & Power Co. at Menomonie 

and Cedar Falls. (See "Regulation " in station description for Red Cedar River 

near Colfax, Wis.).

ICE. Stage-discharge relation not affected by ice owing to relatively warm water discharged from service reservoir.

ACCURACY. Stage-discharge relation changed during high water of March, 1919, but 

has been practically permanent since. Two rating5 curves used during 1919 and 

1920; one, applicable October 1,1918, to March 20,1919, well defined between 610 

and 1,910 second-feet and between 3,910 and 9,220 second-feet and extended outside these limits; the other, applicable March 21,1919, to September 30,1920, well' 

defined between 862 and 9,370 second-feet. Indirect method for shifting control1 

used May 15-20, 1919, with first of the above-mentioned rating curves as basis. 

Water-stage recorder operated satisfactorily except for brief periods. Daily dis>- 

charge ascertained by means of discharge integrator except as noted in footnote to 

tables of daily discharge. Records good except for periods during which gage 

was not in operation for which they may be subject to error.

10,000 second-feet March 17 (high water prevented reading gage); minimum 

discharge, estimated 120 second-feet February 10 (stage-discharge relation affected by ice).

1914-1919: Maximum stage recorded, 8.35 feet June 9, 1914 (discharge, 3,360 

second-feet); on March 17, 1919, the stage rose considerably above 9.5 feet (estimated discharge, 10,000 second-feet); minimum discharge, estimated 105 secondfeet February 4 and 5, 1918 (stage-discharge relation affected by ice).

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. No power plants above station have sufficient capacity to affect natural flow of river.

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

Shifting-channel method used during open-water periods throughout the year; 

basic rating curve, well defined between 240 and 1,650 second-feet. Gage read to 

hundredths twice daily except during winter, when it was read irregularly three 

or four times a week. Daily discharge ascertained by indirect method for shifting control'except as indicated in footnote to table of daily discharge. Records

BLACK RIVER AT NEILLSVILLE, 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, about 1J miles below.

DRAINAGE ABBA. 774 square miles (measured on map issued, by Wisconsin Geological and Natural History Survey, edition of 1911; scale, 1 inch=6 miles).

RECORDS AVAILABLE. April 6, 1905, to March. 31,1909; December 11, 1913, to September 30, 1920.

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

'Bissell.

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

vicinity of bridge.

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

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

overflowed at gage section.

.EXTREMES OF DISCHARGE. Maximum open-water stage recorded during year ending September 30,1919,11.4 feet at 6 a. m. June 24 (discharge, 8,980 second-feet); 

minimum discharge, estimated 30 second-feet February 7-12 (stage-discharge 

relation affected by ice).

Maximum stage recorded during year ending September 30, 1920, 15.2 feet at 

6 a. m. March 26 (discharge, 18,400 second-feet); minimum stage recorded, 1.90 

feet at 7 p. m. August 28 (discharge, about 26 second-feet).

1905-1909 and 1913-1920: Maximum stage recorded, 19.8 feet June 6, 1905 

(discharge, about 29,400 second-feet); minimum discharge probably somewhat 

less than 5 second-feet in February, 1918 (stage-discharge relation affected by ice). 

It is probable that the maximum discharge during flood of October 6, 1911, 

exceeded 29,000 second-feet, but no data are available regarding the stage at the 

gage section.
UPPEK MISSISSIPPI EIVEK BASIN. 12T

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 the 

flow is at a minimum.

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

ice. Rating curve used during 1919, fairly well denned between 40 and 14,000 

second-feet; curve used during 1920 is a revision of the 1919 curve above 11 feet 

(discharge, 8,300 second-feet) and is fairly well defined between 40 and 16,000 

second-feet. Gage read to hundredths twice daily. Stage-discharge relation 

affected by ice, November 30,1918, to March 16,1919, and November 27,1919, to 

March 20,1920. Daily discharge for these periods ascertained by applying to 

rating table mean daily gage height corrected for ice effect by means of discharge 

measurements, observer's notes, and weather records. Open-water records fair 

except for extreme low stages for which they are poor; winter records poor.

LA CROSSE RIVER HEAR WEST SALEM, WIS.

LOCATION. In sec. 32, T. 17 N., R. 6 W., at highway bridge 2 miles west of West 

Salem, La Crosse County, and 10 miles above mouth of river. Dutch Creek 

enters from right 6 miles above station.

DRAINAGE ABBA. 412 square miles (measured on map issued by Wisconsin Geological and Natural History Survey, edition of 1911; scale, 1 inch=6 miles).

RECORDS AVAILABLE. December 22, 1913, to September 30, 1920.

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

by Henry Schucht.

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

wading.

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

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

gage low, and subject to overflow at flood stages. Control for low stages is a 

rocky riffle with a fall of about 6 inches; is apparently drowned out at a stage 

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

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 30, 1919, 8.45 feet at 6 p. m. March 16 (discharge, about 3,620 second-feet); 

minimum stage, 1.05 feet at 6 p. m. July 20 (discharge, 135 second-feet).

Maximum stage recorded during year ending September 30, 1920, 6.65 feet at 

7 a. m. June 17 (discharge, about 2,390 second-feet); minimum discharge, estimated 100 second-feet January 4 (stage-discharge relation affected by ice).

1913-1920: Maximum stage recorded, 8.45 feet at 6 p. m. March 16, 1919 (discharge, about 3,620 second-feet); minimum discharge, estimated 100 second-feet 

January 4,1920 (stage-discharge relation affected by ice).

ICE. Stage-discharge relation seriously affected by ice.
130 SURFACE WATER SUPPLY, 1919HL920, PART V.

REGULATION. Diurnal fluctuation at gage amounting at low stages to from 0.10 to 

0.40 foot, is caused by operation of power plants, especially at Neshonock dam 

a few miles above station.

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

curve well defined between 175 and 1,300 second-feet and fairly well defined 

between 1,300 and 2,200 second-feet. Gage read to quarter-tenths twice daily. 

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

except for periods, December 24, 1918, to January 25, 1919, February 1-10, 

February 27 to March 13, 1919, and December 1, 1919, to March 23, 1920. during 

which stage-discharge relation was affected by ice, for which it was ascertained 

by applying to rating table mean daily gage height corrected for ice effect by 

means of discharge measurements, observer's notes, and weather records. Openwater records good except for low stages, for which they are fair; winter records fair.

UPPER IOWA RIVER NEAR DECORAH, IOWA.

LOCATION. At highway bridge in Freeport, 3 miles below Decorah, Winneshiek 

County, and 4 miles above upper power plant of Interstate Power Co. Nearest 

tributary, Trout Run, which enters from right, 1 mile above station.

DRAINAGE AREA. 560 square miles (measured on United States Geological Survey 

base map; scale, 1:500,000).

RECORDS AVAILABLE. August 27, 1913, to November 21, 1914, and May 12,1919, to 

September 30, 1920.

GAGE. Gurley water-stage recorder on left bank 500 feet above highway bridge, 

installed August 28, 1920. Chain gage attached to handrail of highway bridge 

used prior to that date. Water-stage recorder at datum 3.96 feet higher than 

datum of chain gage. Observer, Mrs. W. D. Gross.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL, AND CONTROL. Bed at chain gage section composed of sand and gravel; 

shifting. Gravel bar below highway bridge forms control for chain gage. Rock 

ledge forms control for water-stage recorder; probably permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded,during period May 12, 1919, 

to September 30, 1920, 11.05 feet at 5 a. m. September 10, 1919 (discharge, 6,220 

second-feet); minimum discharge, 101 second-feet September 17, 1919 (gage 

height, 2.80 feet).

1913-14 and 1919-20: Maximum stage recorded, 11.6 feet May 24, 1914 (dis- 

, charge, about 7,100 second-feet); minimum stage, 2.15 feet September 10 and 

13-16, 1913 (discharge, 37 second-feet).
UPPEB MISSISSIPPI EIVEB BASIN. 133

ICE. Stage-discharge relation affected by ice for short periods during extremely cold 

weather.

REGULATION. Operation of several mills in Decorah may cause slight diurnal fluctuation at gage.

ACCURACY. Stage-discharge relation probably permanent during period for both 

chain gage and water-stage recorder, except as affected by ice. Eating curve for 

chain gage, applicable May 12, 1919, to August 28, 1920, is well denned between 

1,600 and 14,000 second-feet, and fairly well defined between 100 and 1,600, 

second-feet. Rating curve for water-stage recorder, applicable August 29 to 

September 30, 1920, is well denned between 100 and 10,000 second-feet. Chain 

gage read to hundredths twice daily prior to August 28, 1920; mean gage heights 

from water-stage recorder graph thereafter. Daily discharge ascertained by 

applying mean daily gage height to rating table except for period, November 28, 

1919, to March 11,1920, during which stage-discharge relation was affected by ice, 

for which mean discharge was ascertained by applying to rating table mean daily 

gage height corrected for ice effect by means of observer's notes, weather records, 

and comparison with flow of Squaw Creek at Ames, Iowa. Open-water records 

good; winter records fair.

UPPER MISSISSIPPI RIVER BASIN. 135

WISCONSIN RIVER AT WHIRLPOOL RAPIDS, NEAR RHINELANDER, WIS.

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

mouth of outlet of Crescent Lake, which comes in from right, and B miles downstream from power station of Rhinelander Power Co., and 10 milea southwest of 

Rhinelander, Lincoln County.

DRAINAGE AKBA. 1,160 square miles (measured on map issued by Wisconsin Geological and Natural History Survey, edition of 1911; scale, 1 inch=6 miles).

RECORDS AVAILABLE. September 15, 1915, to September 30, 1920. December 1, 

1905, to September 30,1915, records were obtained at a station 3 miles upstream.

GAGE. Stevens continuous water-stage recorder in a wooden shelter on right bank; 

inspected by C. W. Jewell.

DISCHARGE MEASUREMENTS. Made from cable about 150 feet upstream from 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 downstream 

from gage; well denned and permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 4.28 feet at 10 p. m. April 13 (discharge, 3,200 second-feet); minimum 

stage not known.

Maximum stage recorded during year ending September 30, 1920, 5.2 feet at 

2 p. m. April 1 (discharge, 4,520 second-feet); minimum stage recorded, 1.4 feet 

at 6 a. m'. September 27 (discharge, 435 second-feet). It is quite probable that 

the maximum stage occurred during the latter part of March when recording gage 

was not in operation.

1905-1920: Maximum stage recorded, 5.61 feet April 22,1916 (discharge, 5,250 

second-feet); minimum discharge, practically no flow, at old station, during 

August and September, 1907, and June and July, 1908; minimum stage at present 

location, 0.65 foot July 7,1918 (discharge, 165 second-feet). Discharge at present 

location of station will probably never be zero. Minimum discharge caused, 

almost entirely by regulation.

REGULATION. Above the station are 14 reservoirs 6 which are operated by the Wisconsin Valley Improvement Co. for the purpose of regulating the flow in Wisconsin 

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

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

of these various storage reservoirs and the service reservoirs of three power plants 

on the river above, the flow at the station is not natural.

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

curve well denned between 212 and 5,410 second-feet. Operation of water-stage 

recorder satisfactory except as noted in footnote to tables of daily discharge. 

Daily discharge ascertained by means of discharge integrator except as indicated 

in footnote to tables of daily discharge. Open-water records, when water-stage 

recorder was in operation, excellent; records for other periods, poor. -

138 SURFACE WATER SUPPLY, 1919-1920, PART V.

WISCONSIN RIVER 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 Lighting Co. and half a mile 

below mouth of Prairie Elver, which comes in from left.

DRAINAGE AREA. 2,630 square miles.

RECORDS AVAILABLE. November 16, 1902, to September 30, 1920.

GAGE. Stevens water-stage recorder installed September 11, 1914; November 16, 

1902, to June 17,1903, staff gage; June 17,1903, to September 10,1914, chain gage 

attached to downstream side of highway bridge; datum same since June 17, 1903. 

Records prior to June 17,1903, questionable. Recorder inspected by 0. F. Lueck.

DISCHARGE MEASUREMENTS. Made from highway bridge a few feet upstream from 

recording gage.

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

Small island below gage and small rapids on either side probably constitute control. Banks fairly high and are seldom overflowed.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 9.51 feet at 9.30 p. m. April 11 (discharge, 12,900 second-feet); minimum stage recorded, 3.08 feet at 7 a. m. September 1 (discharge, about 490 

second-feet); minimum stage caused .by regulation.

Maximum stage recorded during year ending September 30, 1920, 11.42 feet at 

5 a. m. March 29 (discharge, 19,200 second-feet); minimum stage recorded, 3.84 

feet at 6.30 a. m. August 23 (discharge, 918 second-feet); minimum stage caused 

by regulation.

1902-1920: Maximum stage recorded, about 17.5 feet at 5 a. m. July 24, 1912 

(discharge, about 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 7 which are operated by Wisconsin Valley Improvement Co. for the purpose of regulating the flow in Wisconsin 

River. The aggregate capacity of these reservoirs is about 6f billion cubic feet. 

In addition to the above reservoirs there are on Wisconsin and Tomahawk rivers 

above the station eight dams operated for power.

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

Rating curve fairly well defined between 1,600 and 19,400 second-feet. Operation 

of water-stage recorder very satisfactory. Daily discharge ascertained by means 

of discharge integrator except for few days when water-stage" recorder was not 

operating properly, and except for periods, February 1 to March 21,1919, and December 1, 1919, to March 12, 1920, during which stage-discharge relation was 

affected by ice, for which it was ascertained by means of gage heights from waterstage recorder graph, discharge measurements, and weather records. Openwater records good; winter records fair.

141

LOCATION. In sec. 15, T. 21 N., R. 5 !j., li miles below Nekoosa, Wood County. 

Tenmile Creek enters from left 4 miles^ below station, and Big Roche a Cri Creek^. 

also from left, 38 miles below. j

DRAINAGE AREA. 5,500 square miles (measured on map issued by Wisconsin Geological and Natural History Survey, edition of 1911; scale, 1 inch =6 miles).

RECORDS AVAILABLE. May 21, 1914, to September 30, 1920.

GAGE. Stevens water-stage recorder, instjalled July 18, 1916, in wooden shelter on 

right bank; prior to that date Gurley \fater-stage recorder at same location. Gage 

attended by Henry Mans.

DISCHARGE MEASUREMENTS. Made from cable a short distance upstream from gage 

house.

CHANNEL AND CONTROL. Bed composed of gravel; clean; practically permanent. 

Banks are high and are seldom overflowed.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 10.6 feet at 7 a. m. June 27 (discharge, 26,900 second-feet); minimum: 

stage recorded, 0.71 foot at 8 p. m. October 6 and 8 p. m. September 2 (discharge, 

913 second-feet).

Maximum stage recorded during ye$r ending September 30, 1920, 15.1 feet at 

noon March 28 (discharge, 52,900 second-feet); minimum stage recorded, 0.6- 

foot at 12.30 p. m. September 7 (discharge, 1,010 second-feet).

6-9,1914, as determined by levels run io high-water marks after water had receded 

(discharge, about 54,000 second-feet); minimum stage recorded, 0.45 foot at 11 

a. m. November 7, 1915 (discharge, 595 second-feet); minimum flow is caused by 

regulation.

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. No storage reservoirs discharge into Wisconsin Eiver between Nekoosa 

and Merrill. See "Regulation" in station description of Wisconsin River at 

Merrill (p. 338). Between Nekoosa and Merrill are 12 dams operated for power.

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

Rating curve well defined between 1,450 and 52,000 second-feet. Operation 

of water-stage recorder satisfactory. Daily discharge ascertained by means of 

discharge integrator except for few short periods when operation of water-stage 

recorder was unsatisfactory, and except for periods December 23, 1918, to March 

31, 1919, and December 1, 1919, to M$rch 9, 1920, during which stage-discharge 

relation was affected by ice, for which mean discharge was ascertained by meana 

of weather records and comparison with flow of this river at Merrill, Wis. Openwater records excellent; winter recordb fair.

144 SURFACE WATER SUPPLY, 1919t-1920, PART V.

WISCONSIN RIVER 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; scale, 1 inch=6 miles.)

BECORDS AVAILABLE. December 20, 1902, to December 31, 1903; December 1, 1913, 

to September 30, 1920. 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 en upstream side of bridge; read by William 

Hessler. Elevation of zero of present gage about 12.62 feet above that of gage 

maintained December 20, 1902, to December 31, 1913; elevation of gage during 

period November, 1908, to December 31,1913, as read and published by United 

States Weather Bureau was approximately the same as that of present gage, 

sea-level elevation of which is about 666.2 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 7.98 feet at 5 p. m. April 16 (discharge, about 42,300 second-feet); 

minimum stage recorded, 0.96 foot at 5 p. m. October 14 (discharge, about 3,550 

second-feet); water apparently held in service reservoir of Prairie du Sac dam.

Maximum stage recorded during year ending September 30, 1920, 10.10 feet 

at 5 p. m. April 2 (discharge, 64,400 second-feet); minimum stage recorded, 0.44 

loot at 5 p. m. September 27 (discharge, 3,130 second-feet).

1903 and 1914-1920: Maximum stage recorded, 10.10 feet April 2, 1920 (discharge, 64,400 second-feet); minimum discharge, estimated 2,000 second-feet 

February 11, 1918 (stage-discharge relation affected by ice); water apparently 

held back in service reservoir of Prairie du Sac dam.

 According to records of United States. Weather Bureau 8 (see note under 

"Gage") on June 11, 1881, the river reached a stage of 11.1 feet, and during 

August, 1868, zero on gage; discharge not determined owing to probable changes 

in channel and datum of gage.

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

miles distant; since latter part of 1915 considerable diurnal fluctuation has been 

observed at gage. Owing to regulation by storage in the headwaters, the flow at 

this station is not natural.

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

rating-curves used during 1919 and 1920; one applicable October 1 to March 14, 

1919, fairly well defined between 3,810 and 15,900 second-feet and poorly defined 

outside these limits; the other used as basic curve for the indirect method for 

shifting channel and applicable March 15 to November 30, 1919, and March 23 

to September 30, 1920, fairly well defined between 5,200 and 45,000 second-feet. 

Gage read to hundredths twice daily. Daily discharge ascertained by applying 

mean daily gage height to rating table except as indicated in footnote to tables 

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

UPPER MISSISSIPPI EIVER BASIN. 14T

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, 

which comes in from right, and 8 miles ajjjwe mouth of river.

DRAINAGE AREA. 422 square miles.

RECORDS AVAILABLE. September 18, 1914, to September 30, 1920.

GAGE. Slope gage fastened to concrete posts on right bank of river, installed September 24, 1919; prior to that date, chain gage fastened to cantilever arm on right 

bank; both gages at same datum; read by Frank Sutherland.

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

CHANNEL AND CONTROL. Bed at gage and a short distance below composed of sand; 

may shift; bed at cable composed of heavy gravel. Control is formed by rapids 

about 2,000 feet below gage. When a head of 15 feet is maintained on Rice Lake 

storage dam, in sections 4 and 9, T. 35 N., R. 6 E., backwater will extend half 

way up the rapids, and may affect stage-discharge relation. The maximum head 

maintained during 1919 and 1920 at the reservoir was 14 feet and 9 inches during 

week ending November 29, 1919, which apparently caused no backwater at gage.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 30, 1919, 5.10 feet at 6.10 p. m. April 11 (discharge, 1,270 second feet); minimum stage recorded, 1.76 feet at 6.20 p. m. October 3 and 7.35 a. m. October 4 

(discharge, about 211 second-feet).

Maximum stage recorded during year ending September 30, 1920, 6.17 feet 

about noon March 30 (discharge, 1,770 second-feet); minimum stage recorded, 

1.37 feet at 6 a. m. and 6 p. m. August 28 (discharge, 165 second-feet).

1914-1920: Maximum stage recorded, 6.9 feet April 24, 1916 (discharge, 2,200 

second-feet); minimum discharge, 144 second-feet November 17,1915 (by currentmeter measurement).

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. The following reservoirs are maintained upstream from the station, 

for the purpose of regulating the flow of Wisconsin River:

Dams and reservoirs on Tomahawk River.

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

ice. Rating curve used, poorly defined below 350 second-feet and well defined 

above. Gage read to hundredths twice daily except during winter, when, in 

1919, it was read once a week, and in 1920, it was read only a few times. Daily 

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

for periods indicated in footnote to tables of daily discharge. Open-water records 

good except for low stages, for which they are fair; winter records poor.

154 SURFACE WATER SUPPLY, 191^-1920, PART V.

EAU CLAIRE RIVER AT KELLY, WIS.

LOCATION. In sec. 13, T. 28 N., R. 8 E., at highway bridge three-quarters of a mile 

northeast of Kelly, Marathon County, 1 mile above mouth of Big Sandy Creek, 

which enters from right, and 4| miles above mouth of river.

_ DRAINAGE AREA. 326 square miles (measured on map issued by Wisconsin Geological 

and Natural History Survey, edition of 1911; scale, 1 inch=6 miles).

RECORDS AVAILABLE. January 1, 1914, to September 30, 1920.

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

Woolsey and Merle Rossmiller.

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

CHANNEL AND CONTROL. Bed composed of heavy gravel and rock. Gage is in the 

rapids which form control. Banks medium high and not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 4.45 feet at 8 a. m. June 26 (discharge, 2,500 .second-feet); minimum 

discharge, 63 second-feet, by current-meter measurement March 4.

Maximum stage recorded during year ending September 30, 1920, 6.45 feet at 

8.30 a. m. March 26 (discharge, 5,020 second-feet); minimum discharge, estimated 

55 second-feet January 1, 2, 4, and 5, and March 6-9 (stage-discharge relation 

affected by ice.)

1914-1920: Maximum stage recorded, 6.45 feet March 26, 1920 (discharge, 5,020 

second-feet); minimum discharge, estimated 30 second-feet December 6, 1917 

(stage-discharge relation affected by ice).

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

curve well defined between 71 and 3,150 second-feet. Gage read to quarter-tenths 

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

to rating table, except for periods during which stage-discharge relation was 

affected by ice, for which it was ascertained by applying to rating table mean 

daily gage height corrected for ice effect by means of discharge measurements, 

observer's notes, and weather records, and except for days when gage was not 

read for which it was interpolated. Open-water records good; winter records fair.

BIG EAtT PLE1NE RIVER NEAR STRATFORD, WZS.

LOCATION. In sec. 13, T. 27 N., R. 3 E., at Weber Farm, 2 miles north of Stratford,, 

Marathon County, and 1 mile above Chicago & Northwestern Railway bridgeDill Creek enters from right 5 miles above station.

DRAINAGE AREA. 223 square miles (measured on map issued by Wisconsin, Geological 

,and Natural History Survey, edition of 1911; scale, 1 inch=6 miles).

RECORDS AVAILABLE. July 24, 1914, to September 30, 1920.

GAGE. Slope gage, reading from 1.0 to 15.6 feet, on right bank of river, and vertical 

staff gage, reading from 15 to 18 feet, at upper end of sloping gage; read by Christian 

Weber.

DISCHARGE MEASUREMENTS. Made from highway bridge 1 mile below gage or by 

wading about 1,000 feet below gage.

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

head of rapids 400 feet below gage. Both banks at gage are high and are over- 

. flowed only at stage of about 15 feet and above.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 8.7 feet at 6.30 a. m. August 7 (discharge, 5,330 second-feet); minimum 

stage, 1.34 feet October 3 (discharge, about 4 second-feet).

Maximum stage recorded during year ending September 30, 1920, 10.90 feet at 

4.30 p. m. November 10 (discharge, 8,630 second-feet); minimum stage, 1.25 feet 

at 7 p. m. August 28 and 7 a. m. August 29 (discharge, about 2.5 second-feet).

by levels run to high-water marks.

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

ice. Rating curve well defined between 47 .and 4,000 second-feet; poorly defined 

outside these limits. Gage read to hundredths twice daily. Daily discharge 

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

December 20,1918, to March 31, 1910, and December 28, 1919, to March 27, 1920, 

during which stage-discharge relation was affected by ice, for which the discharge 

was not determined. Records good except for low stages for which they are fair.

. PLOVER RIVER HEAR. STEVENS POINT, WIS.

LOCATION. In sec. 1, T. 24 N., E. 8 E., at Fast Waters highway bridge, 7 miles above 

mouth of river and 5 miles northeast of Stevens Point, Portage County.

DRAINAGE AREA. 136 square miles.

RECORDS AVAILABLE. January 5, 1914, to December 31, 1919, when station was 

discontinued.

GAGE. Vertical staff gage bolted to left abutment, downstream side of bridge; read 

 by M. E. Van Order.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

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

vegetation; permanent. At high stages both banks are overflowed around the 

bridge. Control not well defined but is probably small rapids below gage.

EXTREMES OP DISCHARGE. Maximum stage recorded during period October 1,1918, 

to December 31, 1919, 4.3 feet at 5 p. m. June 27, 1919 (discharge, 1, 230 secondfeet); minimum discharge probably somewhat less than 80 second-feet during 

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

1914-1919: Maximum stage recorded, 4.75 feet June 5, 1914 (discharge, about 

1,570 second-feet); minimum discharge, estimated 45second-feet, February 5-7, 

1917 (stage-discharge relation affected by ice).

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. Two dams above station are used in connection with grist mills, but 

as they have little pondage the flow at gage, except for brief periods, is nearly 

natural.

AOCURAQY. Stage-discharge relation practically permanent except as affected by ice. 

Rating curve fairly well defined between 82 and 410 second-feet; poorly defined 

outside these limits. Gage read to half-tenths twice daily. Daily discharge ascertained by applying mean daily gage height to rating table except for periods 

during which stage-discharge relation was affected by ice, for which it was ascertained by applying to rating table mean daily gage height corrected for ice effect 

by means of discharge measurements) observer's notes, and weather records. 

Open-water records fair except for extreme low stages;, for which they are subject to 

error on account of diurnal fluctuation at gage; winter records poor.

BARABOO RIVER NEAR BARABOO, WIS.

LOCATION. In sec. 33, T. 12 N., E. 7 E., at highway bridge 4 miles downstream 

from Baraboo, Sauk County, 3 miles below creek that rises near Devils Lake and 

comes in from right, and 15 miles above mouth of river.
SURFACE WATER SUPPLY, lM^-1920, PART V.

DRAINAGE AREA. 572 square miles (measured on map issued by Wisconsin Geological and Natural History Survey, edition of 1911; scale, 1 inch=6 miles).

RECORDS AVAILABLE. December 18, 1913, to September 30, 1920.

GAGE. Chain gage, attached to upstream side of bridge; read by Theodore Schneider.

DISCHARGE MEASUREMENTS. Ma.de from downstream side of highway bridge to 

which gage is attached.

CHANNEL AND CONTROL. Bed composed of sand and mud. Control not well defined. 

Water is confined to one channel except at flood stages when right bank is overflowed for a distance of 1,000 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919,15.02 feet at 4 p. m. March 19 (discharge, about 4,070 second-feet); minimum stage, 1.00 foot at 8 a. m. September 8 (discharge, about 86 second-feet). 

Maximum stage recorded during year ending September 30, 1920, 17.08 feet 

at 8 a. m. June 22 (discharge, 7,180 second-feet); minimum stage. 1.34 feet at 

8 a. m. July 25 (discharge, 97 second-feet).

1914-1920: Maximum stage recorded, about 17.5 feet March 26,1917 (discharge, 

about 7,900 second-feet)9 ; 'minimum stage, 0.71 foot July 26, 1916 (discharge, 76 

second-feet).

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. In the vicinity of Baraboo, 4 miles above station, there are four dama, 

and one at Reedsburg, 18 miles above station. Smaller plants are also operated 

on tributaries. The operation of these various plants causes diurnal fluctuation 

at gage of about 0.3 foot at low stages. Mean monthly discharge probably represents nearly the natural flow.

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

rating curves used; one, applicable October 1, 1918, to March 7, 1919, fairly well 

denned between 170 and 2,600 second-feet, the other, applicable March 8, 1919, 

to September 30, 1920, fairly well denned between 150 and 6,000 second-feet and 

was used as basic curve for the indirect method for shifting control during periods 

March 24 to November 27,1919, and March 16 to September 30, 1920. Gage read 

to hundredths twice daily. During periods when shifting-control method was 

not used daily discharge was ascertained by applying mean daily gage height to 

rating table except as indicated in footnote to tables of daily discharge. Records fair.

MISSISSIPPI EIVER BASIN,

KICEAPOO STVER AT GAYS MILLS, WIS.

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

Norwood Mill, in Gays Mills, Crawford County, 25 miles above mouth of river, 

and 2 miles below mouth of Tainter Creek, which enters from right.

DRAINAGE AREA. 629 square miles (measured en map issued by Wisconsin Geological 

and Natural History Survey, edition of 1911; scale, 1 inch=6 miles).

RECORDS AVAILABLE. December 25, 1913, to September 30> 1920. '.

GAGE. Chain gage fastened to downstream side of bridge; read by N. T. Norwood 

and Robert Atwood.

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

CHANNEL AND CONTROL. Bed composed of rock covered by a deposit of sand. Banks 

at gage section fairly high and not subject to overflow at ordinary high-water 

stages. Control is at head of small rapids about 300 feet below gage; not permanent; the plotting of discharge measurements indicates that at a stage of about 

2 feet on the gage, the control is changed to some point below, causing a reversal 

in the rating curve.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30,1919,11.9 feet at 5 p. m. March 17 (discharge, about 3,950 second-feet); minimum stage, 1.10 feet at 5.45 p. m. September 16 and 9 a. m. September 28 (discharge, about 172 second-feet).

Maximum stage recorded during year ending September 30, 1920, 10.5. feet.at 

5.45 a. m. June 18 (discharge, 3,200 second-feet); minimum discharge, estimated 

140 second-feet January 5 (stage-discharge relation affected by ice).

1914-1920: Maximum stage recorded, 15.05 feet March 24, 1917 (discharge, 

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

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

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. Mills at Gays Mills immediately above the station, at Soldiers Grove, 

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

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

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

poorly defined rating curve used during 1919 and 1920; curve was used by direct 

method October 1, 1918, to March 18, 1919, and as basic curve for the indirect 

method for shifting control, March 19 to November 30, 1919, and March 21 to 

September 30, 1920. Gage read to quarter-tenths twice daily. During periods 

when shifting-control method was not used, daily discharge was ascertained by 

applying mean daily gage height to rating table except for periods, November 27 

to December 8, 1918, December 26, 1918, to January 21, 1919, February 2-10, 

February 27 to March 7, 1919, and December 1, 1919, to March 20, 1920, during 

which stage-discharge relation was affected by ice, for which it was ascertained 

by applying to rating table mean daily gage height corrected for effect of ice 

by means of discharge measurements, observer'3 notes, and weather records. 

Records poor.

168 SURFACE WATER SUPPLY, 1919-1920, PART V.

TURKEY ,/.UVER AT GARBER, IOWA.

LOCATION. In sec. 36, T. 92 $ ., R. 4 W., at single-span highway bridge at Garber, 

Clayton County, 800 feet above mouth of Wayne Creek, which enters from right, 

and 1 mile below mouth of Volga Eiver, which enters from right.

DRAINAGE AREA. 1,530 square miles (measured on map issued by United States 

Geological Survey; scale 1 to 500,000).

RECORDS AVAILABLE. August 29, 1913, to November 30, 1916; May 14, 1919, to September 30, 1920.

GAGE. Chain gage attached to handrail on downstream side of bridge; read by E. 

J. Prolow.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand and mud; shifting. Low-water control is a gravel bar. Right bank high; left bank subject to overflow at extreme 

high water.

EXTREMES OF DISCHARGE. Maximum stage recorded during the year ending September 30, 1919, 16.47 feet at 7 a. m. June 4 (discharge, 13,100 second-feet); minimum stage, 3.50 feet August 30 to September 9 (discharge, 250 second-feet).

Maximum stage recorded during year ending September 30, 1920, 14.41 feet at 

8 a. m. March 12 (discharge, 10,500 second-feet); minimum stage, 3.61 feet at 6 

p. m. August 19 (discharge, 334 second-feet).

1913-1916; 1919 and 1920: Maximum stage recorded, 22.0 feet June 3, 1916 

(discharge, about 20,300 second-feet); minimum stage, 2.70 feet September 5 and 

7, 1913 (discharge, 100 second-feet).

The highest stage within the last 30 years probably occurred May 18, 1902, 

when a stage of about '23.7 feet referred to gage datum was reached, as indicated 

by high-water marks on A. F. Grafe's residence in Garber.

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

REGULATION. Operation of an electric light plant and grist mill at Elkader about 

15 miles upstream may cause slight diurnal fluctuation at gage.

ACCURACY. Stage-discharge relation changed several times during period of record. 

Four fairly well-defined rating curves used as follows: August 29, 1913, to January 

29,1914, and June 16, 1914, to August 5, 1915; January 30 to June 15, 1914; August 6, 1915, to June 4, 1916, and May 14, 1919, to September 30, 1920; June 5 to 

November 29, 1916. Gage read to quarter-tenths twice daily during 1913 and 

1914, and to hundredths once daily beginning March 31, 1915.- Daily discharge 

ascertained by applying mean daily or daily gage height to rating table except 

ior periods June 5 to September 10, 1919, and August 22 to September 30, 1920, 

for which it was ascertained by means of the indirect method for shifting control. 

Records subject to error on account of uncertainty in determining time of changes 

in stage-discharge relation, and also because of fact that'other changes may have 

occurred which are indeterminate on account of lack of discharge measurements.

1919 and 1920.

ROCK RIVER AT AFTON, WIS.

LOCATION. On line between sees. 22 and 27, T. 2 N., E. 12 E., at highway bridge in 

Afton, Eock County, 9 miles above Illinois State line. Bass Creek enters from 

right three-quarters of a mile below station.

DRAINAGE AREA. 3,190 square miles (measured on map issued by Wisconsin Geological and Natural History Survey, edition of 1911; scale, 1 inch = 6 miles).

EECORDS AVAILABLE. February 5, 1914, to September 30, 1920.

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

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

CHANNEL AND CONTROL. Bed composed of gravel and clean silt; practically permanent. Banks medium high and are not overflowed to any extent at flood stages. 

Control not well defined.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 4.7 feet at 5.45 p. m. April 23 (discharge, 3,340 second-feet); minimum 

stage, 0.38 foot at 4.50 p. m. August 31 (discharge, about 428 second-feet).

Maximum stage recorded during year ending September 30, 1920, 9.25 feet at 

4.30 p. m. April 1 (discharge, 10,000 second-feet); minimum stage, 0.58 foot at 

5 p. m. September 19 (discharge, 481 second-feet).

1914-1920: Maximum stage recorded, 10.51 feet at noon March 26, 1918 (discharge, 12,700 second-feet); minimum stage recorded, 0.38 foot August 31, 1919 

(discharge, about 428 second-feet).

ICE. Stage-discharge relation seriously affected by ice.

EEGULATION. Operation of power plants at Janesville and above causes fluctuations 

at the gage during low stages.
176 SURFACE WATER SUPPLY, 1919HL920, PAET V.

 ACCURACY. Stage-discharge relation permanent.. Rating curve well defined between 638 and 12,700 second-feet. Gage read to hundredths twice daily. Daily 

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

for periods during which stage-discharge relation was affected by ice, for which 

it was ascertained by applying to rating table mean daily gage height corrected 

for ice effect by means of discharge measurements, observer's notes, and weather 

records, and except for periods during which no gage readings were obtained for 

which mean discharge was ascertained by comparison with flow of Rock River 

at Indian Ford dam and at gaging station at P.ockford, 111. Op en-water records 

excellent, except for periods of extreme low water for which they are fair, and 

except for periods when no gage readings were obtained, for which they may be 

subject to error; winter records roughly approximate.

MISSISSIPPI RIVEB BASIN*

HOCK RIVER AT ROCKTORD, ILL.

LOCATION. In sec. 34, T. 44 N., R. 1 E., at highway bridge at Nelson Avenue, Rockford, Winnebago County, 1 mile below mouth of Kent Creek.

DRAINAGE AREA. 6,520 square miles.

RECORDS AVAILABLE. July 30,1914, to April 30,1919, when station was discontinued.

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

DISCHARGE MEASUREMENTS. Made from upstream side of bridge.

CHANNEL AND CONTROL. Bed composed of coarse gravel and rock; may shift during 

high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during period October 1, 1918,

to April 30, 1919, 11.3 feet at 7 a. m. March 19 (discharge, 24,600 second-feet);

minimum stage, 0.82 foot at 5.30 p. m. October 20 (discharge, 845 second-feet).

1914-1919: Maximum stage recorded, 13.0 feet March 30 and 31, 1916 (discharge

32,000 second-feet); minimum discharge recorded, 483 second-feet, August 9,1914.

REGULATION. Operation of power plant at dam 2 miles upstream in Rockford causes 

fluctuation at gage. During low stages water is stored at night for use in manufacturing plants during day.

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

ice during January. Rating curve fairly well defined. Gage read to hundredth^ 

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 for medium and high stages during open-water periods; probably somewhat 

too large for low stages on account of gage readings having been taken during 

day, when flow owing to regulation at dam, was somewhat greater than during 

night; winter records poor.

The following discharge measurement was made by H. C. Beckman: 

April 9, 1919: Gage height, 4.24 feet; discharge, 4,780 second-feet.

Daily discharge, in second-feet, of Rock River at Rockford, III., for the period Oct. 1, 1918,

to Apr. 30, 1919.

BOCK RIVER AT LYNDON, ILL.

LOCATION.: In sec. 21, T. 20 N.. R. 5 E,, at highway bridge known as Lyndon Bridge, 

in eastern part of Lyndon, Whiteside County, 10 miles above Rock Creek and*20 

miles below dam at Sterling.

DRAINAGE AREA. 9,010 square miles.

RECORDS AVAILABLE. November 24, 1914, to September 30, 1920.

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; practically permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 16.5 feet at 7 a. m. March 20 (discharge, 37.000 second-feet); minimum 

stage recorded, 4.05 feet at 7 a. m. October 7 and 6 p. m. October 10 (discharge, 732 

second-feet).

Maximum stage recorded during year ending September 30, 1920, 16.29 feet at 

7 a. m. March 27 (discharge, 36,200 second-feet); minimum stage recorded, 4.72 

feet at 8 a. m. August 1 (discharge, 1,360 second-feet).

1915-1920: Maximum stage recorded, 19.6 feet February 16, 1918 (discharge 

not1* determined1 because of backwater from ice); maximum open-water stage 

recorded, 17.0 feet March 28,1916 (discharge, 39,500 second-feet); minimum stage, 

3.72 feet September 27, 1918 (discharge, 536 second-feet).

DIVERSIONS. Water is diverted at Sterling dam to feed Illinois and Mississippi canal; 

probably averages about 100 second-feet.

REGULATION. Flow past gage is regulated by power plants in city of Sterling and 

above. Diurnal fluctuation is quite large at low stages.

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

Rating curve well denned between 700 and 25,000 second-feet; fairly well denned 

beyond those limits. Gage read to hundredths twice daily. Daily discharge 

ascertained by applying mean daily gage height to rating table except as indicated 

in footnote to tables of daily discharge. Open-water records good for medium 

stages, and fair for high and low stages; winter records poor.

PECATONICA RIVER AT DILL, WIS.

LOCATION. In sec. 6, T. 1 N., K. 6 E., at Illinois Central Railroad bridge at Dill 

(Ramona post office), Green County, 1 mile*below junction of East and West 

branches of Pecatonica River and 9 miles above Illinois State line.

DRAINAGE AREA. 959 square miles (measured on map issued by Wisconsin Geological 

and Natural History Survey, edition of 1911; scale, 1 inch=6 miles).

RECORDS AVAILABLE. February 9, 1914, to September 30, 1919, when station was 

discontinued.

GAGE. Chain gage fastened to downstream side of bridge; read by S. A. Frank. 

Prior to August 2,1916, vertical staff gage on left abutment.

DISCHARGE MEASUREMENTS. At low and medium stages made from downstream 

side of highway bridge about 400 feet above gage; during extremely high water 

considerable water overflows to left of highway bridge and measurements are made 

from railroad bridge to which gage is attached.

CHANNEL AND CONTROL. Bed composed of sand and mud; shifting. Banks medium 

high, and are overflowed at flood stages. Except during extreme flood stages all 

the water passes' under the railroad bridge to which the gage is fastened. There 

, is little fall in the river below the gage and no well-defined control.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 13.7 feet about 

noon March 17 (discharge, about 6,770 second-feet); minimum stage, 0.56 foot 

at 5 p. m. November 25 (discharge, about 166 second-feet).

1914-1919: Maximum stage recorded, 19.1 feet Mirch 27, 1916, determined 

from flood marks by leveling (discharge, about 13,100 second-feet); minimum 

stage, 0.56 foot November 25, 1918 (discharge, about 166 second-feet). '

ICE .-^Stage-discharge relation affected by ice.
UPPER MISSISSIPPI JEUVER BASIJf. 183

tion of dams at Argyle, on East Branch of Pecatonica River, 

and at Darlington, on West Branch of Pecatonica River, cause little if any diurnal 

fluctuation at gage.

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

curves used, both poorly denned; one, applicable October 1 to March 11, was used 

directly, the other, applicable March 12 to September 30,was used directly except 

during periods March 12-20 and August 1 to September 30, during which indirect 

method for shifting channel was used. Daily discharge ascertained by applying 

mean daily.gage height to rating table except for periods during which indirect 

method for shifting .channel was used and except for periods during which stagedischarge relation was affected by ice, for which it was ascertained by applying to 

rating table mean daily gage height.corrected for ice effect by means of observer's 

notes and weather records. Open-water records fair; winter records subject to 

error.

UPPER MISSISSIPPI KIVER BASIF. 185

PECATONICA RIVER AT FREEPORT, ILL.

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

a mile east of Illinois Central Railroad station at Freeport, Stephenson County, 

and 2 miles above mouth of Yellow Creek.

DRAINAGE AREA. 1,330 square miles.

RECORDS AVAILABLE. September 11,1914, to September 30,1920.

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

DISCHARGE MEASUREMENTS. Made from upstream side of bridge.

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

bank of medium height and is overflowed during high water; at stages above 

about 16.0 feet part of the flow passes over left bank and through East Freeport.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30,1919,17.6 feet at 4.30 p. m. March 16 (discharge, 10, OOd second-feet); minimum 

stage, 2.9 feet at 5.30 p.m. November 24 (discharge, 222 second-feet).

Maximum stage recorded during year ending September 30, 1920, 15.5 feet 

at 5 p. m. March 16 (discharge, 5,380 second-feet); minimum stage, 4.28 feet at 

7 a. m. September 20 (discharge, 425 second-feet).

1914-1919: Maximum stage recorded, 19.4 feet March 28, 1916 (discharge, 

17,000 second-feet); minimum discharge, 200 second-feet at 5 p. m. December 

14, 1917.

ICE. Stage-discharge relation affected by ice.

REGULATION. Operations at dam and power plant three-quarters of a mile upstream 

regulate flow past gage; only slight diurnal fluctuation is noticeable.

ACCURACY. Stage-discharge relation changed March 22, 1919, and again on May 

2,1919; seriously affected by ice. Three rating curves used during 1919 and 1920, 

all of which are revisions of old rating curve at low or medium stages; first curve, 

applicable October 1-18,1918, and March 23 to May 2,1919, is fairly well defined 

throughout; second curve, applicable, October 19, 1918, to March 22, 1919, is 

well defined between 552 and 6,260 second-feet; third curve, applicable May 

3, 1919, to September 30, 1920, is 'well defined between 350 and 7,000 secondfeet and fairly well defined outside these limits. Gage read to hundredths twice 

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

table except for periods December 22, 1918, to January 20, 1919, February 7-10, 

1919, March 1-10, 1919, and December 1, 1919, to March 10, 1920, during which 

stage-discharge relation was affected by ice, for which mean discharge was ascertained by means of gage heights, observer's notes, and weather records. Open 

water records good for medium and high stages, fair for low stages; winter records 

poor.

No discharge measurements were made at this station during year ending September 

30,1920.

Eight bank of medium height; seldom overflowed; left bank at gage is overflowed at stage of approximately 6.8 feet on gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 8.7 feet at 8.30 a. m. March 17 (discharge, about 6,380 second-feet); 

minimum discharge, about 60 second-feet at 6.30 p. m. September 7 (gage height, 

0.90 foot).

Maximum stage recorded during year ending September 30, 1920, 6.35 feet at 

8.30 a. m. October 6 (discharge, 2,520 second-feet); minimum discharge estimated 125 second-feet January 4 (stage-discharge relation affected by ice).

1914-1920: Maximum stage recorded, 11.4 feet September 13, 1915 (discharge, 

about 13,000 second-fee,!); minimum stage recorded, 0.7 foot at 5 a. m. September 

8, 1918.(discharge, determined,from extension of rating curve, about 54 secondfeet); water was undoubtedly being held at dam at Brodhjead.

188 SURFACE WATER SUPPLY, 1919-1920, PART V.

REGULATION. Operation of a power plant at Brodhead, 2 miles above station causes 

slight fluctuation at gage during low water, but the pondage is small and monthly 

discharge represents very nearly the natural flow. There are two plants farther 

upstream, but their operation probably has no effect on discharge at the gage.

ACCURACY. Stage-discharge relations changed rduring , high .water of March, 1919; 

seriously affected by ice. Rating curve used October 1,1918, to March 21, 1919, 

fairly well defined between 108 and 4,500 second-feet; curve used March 22,1919, 

to September 30, 1920, fairly well defined between 80 and 510 second-feet, poorly 

defined outside these limits. Gage read to quarter-tenths twice daily. Daily 

discharge z ..certained by applying mean daily gage height to rating table except 

for period March 14-21,1919, when indirect method for shifting channel was used, 

and except for periods, January 2-19, February 4-12, March 1-8,1919, and November 28,1919, to March 10,1920, during which stage-discharge relation was affected 

by ice, for which daily discharge was ascertained by applying to rating table mean 

daily gage height corrected for ice effect by means of discharge measurements, 

observer's notes, and weather records. Open-water records fair; winter records 

poor for 1919 and fair for 1920.

LOCATION. In sec. 23, T. 84 N., R. 18 W., at Third Avenue Mghway bridge, 1 mile 

north of Marshalltown, Marshall County, and 1 mile below site of old gaging 

station. Asher Creek enters from left 1 mile above station, Burnett Creek from 

Feft 1 mile below, and Linn Creek from right 2**aile& below.

DRAINAGE ABEA. 1,380 square miles (measured on map issued by United Stages 

Geological Survey; scale, 1 to 500,000).

REcombs AVAILABLE. May 21,~1916, to (September 30, 1920, February.23, J^OS, to 

August 8,1903, from old site 1 mile above present station.

GAGE. Chain gage attached to downstream handrail of bridge, 60 feet from right 

pier; read by B. S. Beehrle.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand; subject to shift. Banks subject to, 

overflow, the left bank at stages above 13 feet.

EXTREMES OP DISCHARGE. Maximum stage recorded during the year ending September 3d, 1919,12.74 feet at 12.10 p. m. March 17 (discharge, 7,030 second-feet); 

minimum stage, 2.00 feet at 12.30 p. m. September 13 (discharge, 80 second-feet). 

Maximum stage recorded during year ending September 30, 1920, 12.35 feet 

October 6 (discharge, 6,450 second-feet); minimum discharge, estimated 130 

second-feet February 19, 21, 26, and 27 (stage-discharge relation affected by ice). 

1915-1920: Maximum stage recorded, 17.74 feet June 4, 1918 (discharge, 42,000 

second-feet); minimum stage, 1.86 feet November 24, 1917 (discharge, about.2 

second-feet).

ICE. Stage-discharge relation affected by ice for short periods during extremely cold 

weather.

REGULATION. Operation of a power plant at Eldora about 25 miles upstream causes 

slight diurnal fluctuation at gage during periods of low water.

ACCURACY. Stage-discharge relation practically permanent for medium and high 

stages; changed for low stages during ice break-up in March,, 1920; seriously 

affected by ice. Rating curve used October 1, 1918, to March 5, 1920, well 

defined throughout; curve used March 6 to September 30,1920, is a revision of 

former curve at low-water end and is well defined throughout. Gage read to hundredthsonce daily or oftener during floods, except August 22 to November 5,1919, 

when bridge was being repaired, during which period observations were discontinued from August 22 to September 7, and readings were obtained from a temporary gage September 8 to November 5. Daily discharge ascertained by applying daily gage height to rating table except as indicated in footnote to tables of 

daily discharge. Open-water records good; winter records fair.

Geological Survey; scale, 1 to 500,000). 

EECORDS AVAILABLE. October 30, 1913, to September 30, 1920; June 1, 1903, to

July 21, 1906, from gaging station three-quarters of a mile upstream. 

GAGE. Chain gage attached to upstream handrail of bridge about 40 feet from left

pier of first span from left bank; read by Albert postal. 

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

a boat about 1,000 feet downstream from bridge. 

CHANNEL AND CONTROL. Bed composed of sand; shifting. Eight bank high and

not subject to overflow; left bank subject to overflow at ordinary high stages under

a pile trestle approach to the bridge and at extreme high stages beyond left end

of the approach also.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 11.6 feet at 9.40 a. m. May 7 (discharge, 12,800 second-feet); minimum 

stage; 0.38 foot at 1.30 p. m. September 13 (discharge, 79 second-feet).

Maximum stage recorded during year ending September 30, 1920, 9.3 feet 

March 17 and 18 (discharge, 8,130 second-feet); minimum stage, 0.60 foot August 

17 (discharge, 280 second-feet).

1903-1806 and 1913-1920: Maximum stage recorded, 19.4& feet June 7, 1918 

(discharge, 36,200 second-feet); minimum discharge about 10 second-feet December 26, 1916.

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

periods of ice effect.

REGULATION. Considerable diurnal fluctuation is caused at low stages, owing to 

operation of power plant above station.

ACCURACY. Stage-discharge relation changed during flood of early October, 1919; 

affected by ice. Two well defined rating curves used; one is applicable 

October 1,1918, to September 30, 1919, and the other, which is a revision of the 

former curve below gage height 8.6 feet (discharge, 7,080 second-feet) is applicable October 1,1919, to September 30, 1920. Gage read to hundredths once 

daily except during frozen periods, January 1-21. 1919, and December 16, 1919, 

to January 29,1920. Daily discharge ascertained by applying daily gage height 

to rating table except as indicated in footnote to tables of daily discharge. 

Open-water records good except for low-water periods during which considerable diurnal fluctuation occurred, for which they are fair; winter records fair.

station at Wapello, Louisa County, and 20 miles above mouth of river. No important tributaries enter near station.

DRAINAGE AKEA. At gaging station, 12,480 square miles; at mouth, 12,600 square 

. miles (measured on map issued by United States Geological Survey; scale, 1 to 

500^)00).

RECORDS AVAILABLE. February 26, 1915, to September 30, 1920.

GAGE. Chain gage attached to highway bridge near center of first span from right 

abutment; read by C. W. Warren.

DISCHARGE MEASUREMENTS. Made from bridge to whicl| gage is attached.

CHANNEL AND CONTROL. Bed composed of sand and gravel; shifts slightly. Right 

bank high and not subject to overflow. .Levee along left bank broke in June, 

1918, causing flooding of considerable cultivated land.
UPPER MISSISSIPPI RIVER BASIN. 197

EXTREMES op DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 10.83 feet at 1 a. m. March 23 (discharge, 38,100 second-feet); minimum 

stage, -0.15 foot August 29 (discharge, 620 second-feet).

Maximum stage recorded during year ending September 30, 1920, 9.7 feet at 

7 a. m. March 29 (discharge, 32,200 second-feet); minimum discharge, estimated 

1,800 second-feet January 29-31 (stage-discharge relation affected by ice).

1915-1920: Maximum stage recorded, 14.94 feet June 8, 1918 (discharge, 63,100 

second-feet); minimum discharge, about 400 second-feet December 15-17, 1916 

(stage-discharge relation, affected by ice). 

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

ICE. Stage-discharge relation seriously affected by ice.

ACCURACY. Stage-discharge relation practically permanent during 1919 and to March 

31, 1920, except as affected by ice; from April 1 to September 30, 1920, a gradual 

shift was taking place. One well defined rating curve used during 1919 and 1920; 

used direct October 1, 1918, to March 31, 1920, and as basic curve for shifting 

channel method April 1 to September 30,1920. Gage read to hundredths once 

daily except during winter. Daily discharge ascertained by applying daily gage 

height to rating table except as indicated in footnote to tables of daily discharge 

and except for period during which indirect method for shifting channel was 

used. Open-water records excellent for 1919 and good for 1920; winter records 

fair.

CEDAB. RIVER AT JAHESVILLE, IOWA.

LOCATION. In sec. 35, T. 91 N., R. 14 W., at highway bridge in Janesville, Bremer 

County, a quarter of a mile above old gaging station and 3 miles above junction 

with Shellrock Elver.

DRAINAGE AREA. 1,660 square mfleB (measured on map issued by United i&tates 

Geological Survey; scale, 1 to 500,000).

RECORDS AVAILABLE. April 27, 1905, to September 30, 1906; May 26, 1915, to September 30, 1920.

GAGE. Chain gage attached to downstream handrail of center span of highway 

bridge, installed July 26, 1919. Prior to that date a chain gage attached to 

Illinois Central Railroad bridge, a quarter of a mile downstream, was used. 

Gage read by Mrs. Lydia Matz and Miss Lizzie Ulrich.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel. Ruins of an old grist 

mill dam forms control; probably permanent.
200 SURFACE WATER SUPPLY, 191£~1920, PART V.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 8.6 feet April 11 and 12 (discharge, 6,700 second-feet); minimum stage, 

1.72 feet at 7.40 a. m. September 2 (discharge, 161 second-feet).

Maximum stage recorded during year ending September 30, 1920, 7.27 feet at 

5.40 -pi m. March 28.(discharge, about 7,560 second-feet); minimum stage, 1.60 

feet, July 23 to 27 (discharge, about 118 second-feet).

1905-6 and 1915-1920: Maximum discharge recorded, 22,600 second-feet March 

28, 1906; minimum discharge recorded, 100 second-feet November 3, 1915.

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

during winter.

REGULATION. Slight diurnal fluctuation at low stages is caused by operation of power 

plant at Waverly, 9 miles above station.

ACCURACY. Stage-discharge relation practically permanent for both locations of gage. 

Rating curve for old gage location, used March 26 to July 21, 1919, is fairly well 

defined; curve for new gage location, used after July 21, 1919, is well denned 

between 200 and 2,000 second-feet; extended beyond these limits and may be in 

error. Gage read to hundredths once daily except during winter and periods 

noted in footnote to tables of daily discharge. Daily discharge ascertained by 

applying daily gage height to rating table except as indicated in footnote to tables 

of daily discharge. Records good for low and medium stages during 1920; fair 

for 1919 and for high stages in 1920.

CEDAR RIVER AT CEDAR RAPIDS, IOWA.

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

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

DRAINAGE AREA. At gaging station, 6,640 square miles; at junction with IowaRiver, 7,930 square miles (measured on map issued by United States Geological

Survey; scale, 1 to 500,000).

RECORDS AVAILABLE. February 14, 1903, to September 30, 1920. 

GAGE. Gurley water-stage recorder on right bank, in rear of plant of Iowa Windmill

& Pump Co.; installed August 20, 1920. Prior to that date an inclined staff

gage at same location and same datum was used. Elevation of zero of both gages

from Northwestern Railroad levels, 723.03 feet above sea level. Observer, R. S.

Toogood. 

DISCHARGE MEASUREMENTS. Made usually from upstream side of Eighth Avenue

bridge. 

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

practically permanent. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September

30, 1919, 11.4 feet March 20 (discharge, 29,700 second-feet); minimum stage, 2.9

feet September 16 and 17 (discharge, 775 second-feet). 

Maximum stage recorded during year ending September 30, 1920, 7.5 feet

March 30 (discharge, 14,400 second-feet); minimum discharge, estimated 550

second-feet February 4 and 7 (stage-discharge relation affected by ice). 

1902-1920: Maximum stage recorded, 17.2 feet April 1, 1912, and March 26,

1917 (discharge, 54,100 second-feet); minimum discharge probably somewhat

less than 400 second-feet during latter part of December, 1916 (stage-discharge

relation affected by ice).

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

stage was about 20 feet (discharge, about 65,000 second-feet).
tTPPEE MISSISSIPPI RIVER 208

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

swift current and the proximity of the power plant keeps measuring section open 

during mild winters.

REGULATION. Since 1917, operation of power plant half a mile above gage has 

caused marked diurnal fluctuation during periods of low water. There is no dam 

below gage which might cause backwater.

ACCURACY. Stage-discharge relation practically permanent except as effected by ice. 

Rating curve well deftaed abote 1,00Q s^ce»d*-fffet. <3$ge read tp tenths onc$ 

daily prior to August 20, 1920; since that date a continuous record has been 

obtained from the water-stage recorder. Daily discharge prior to August 20, 1920, 

ascertained by applying daily gage height to rating table, except lor period, 

November 28, 19^.9, to March 16, 1920, during which, stage-discharge relation was 

affected by ice, for which it w$s ascertained by applying to rating table daily gage 

height corrected for ice effect by means of discharge measurements, observer'? 

notes, and weather records; subsequent to August 20, 1920, daily discharge was 

ascertained by use of discharge integrator. Records excellent except for periods 

of low water prior to installation of water-stage, recprder, and except for period ol 

ice effect, for which they are fair.

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

SHELLROCK RIVER NEAR OLARKSVILLE, IOWA.

LOCATION. In T. 92 N., R. 16 W., at highway bridge 1J miles northwest of Clarksville, Butler County, and 25 miles above junction with Cedar River. No large 

tributaries enter for several miles above or below.

DRAINAGE AREA. 1,660 square miles at station; 2,680 square miles at junction with 

Cedar River (measured on map issued by United States Geological Survey; scale, 

1 to 500,000).

RECOUPS AVAILABLE. May 28, 1915, to September 30, 1920,

GAGE. Chain gage attached to handrail on upstream side of bridge, 75 feet from 

right abutment; read by Mrs. H. H. Sherburne.

DISCHABGE MEASTJEEMENTS. Made from upstream side of bridge to which gage is 

attached or by wading.

CHANNEL AND CONTROL. Bed composed of rock and sand; probably permanent. 

Right bank high and not subject to overflow; left bank probably subject to overflow at extreme high stage.
206 SU-KFACE WATER SUPPLY, 1919-1920, PART V.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 10.49 feet at 11.10 a. m. March 16 (discharge, 9,510 second-feet); minimum stage, 1.09 feet September 23 and 24 (discharge, 138 second-feet).

Maximum stage recorded during year ending September 30, 1920, 6.5 feet at 

7.15 a. m. May 23 (discharge, 4,310 second-feet); minimum discharge recorded, 

114 second-feet January 7, by current-meter measurement.

1915-1920: Maximum discharge recorded, 12,200 second-feet June 2, 1916; 

minimum discharge, estimated 100 second-feet December 10-13, 1916.

In April, 1907, a stage of about 16.5 feet was reached (discharge, about 19,000 

second-feet).

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

REGULATION. Operation of power plant at Greene, 10 miles upstream, may cause

slight diurnal fluctuation at low stages.

ACCURACY. Stage-discharge relation changed during high water of March, 1919. 

Rating curve used October 1, 1918, to March 16, 1919, well defined between 200 

and 10,000 second-feet; curve used March 17, 1919, to September 30, 1920, well 

defined between 125 and 10,000 second-feet; extended beyond these limits and 

may be in error. Gage read to hundredths once daily. Daily discharge ascertained by applying daily gage height to rating table except for days of no gage 

reading for which it was ascertained by estimation or interpolation and except 

for days of sudden fluctuation in stage for which it was ascertained by integrating 

hydrographs of stage drawn by means of several extra gage readings. Records 

good except for February, 1919, for which they may be in error, owing to effect 

of ice.

SKUNK RIVER AT AUGUSTA, IOWA.

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

Augusta post office, Des Moines County, and 12.2 miles from mouth of Skunk 

River where it empties into pond of Mississippi River Power Co., 32. 2 miles 

above dam at Keokuk, Iowa.

DRAINAGE ABEA. At gaging station 4,290 square miles; at mouth 4,350 square miles 

(measured on map issued by United States Geological Survey; scale, 1 to 500,000).

RECORDS AVAILABLE. October 1 to November 15, 1913; May 27,1915, to September 

30, 1920.

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

abutment; read once daily by L. E. Williamson. Zero of chain gage 528.55 feet 

above mean sea level, Memphis datum. Staff gage attached to downstream left 

side of middle pier, used by engineers of the Hydraulic Engineering Co. of Maine 

during 1913; taken out by ice in spring of 1914. Datum of staff gage approximately 

0.73 foot higher than datum of chain gage.

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

wading.

CHANNEL AND CONTROL. Bed composed of sand; shifting. Right bank high and is 

not overflowed; left bank is overflowed at extreme high stages. Remains of old 

mill dam 600 feet below gage forms control; permanent. The fall over the dam is 

about 3 ieet at medium low stages. Backwater from Mississippi River occurs 

once in about 50 years.
UPPER MISSISSIPPI RIVER BASI2S". 213

KEGULATION. Natural discharge at Augusta occasionally affected at extreme low 

stages, by storage of water at Oakland Mills, 30 miles upstream.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 15.25 feet at 3 p. m. May 4 (discharge, 21,600 second-feet); minimum 

stage, 1.29 feet September 8 (discharge, 26 second-feet, by current-meter measurement); minimum caused by artificial regulation.

Maximum stage recorded during year ending September 30, 1920,16.25 feet at 

7 a. m. April 21 (discharge, 24,500 second-feet); minimum stage, 2.03 feet August 

27 and September 2 (discharge, 244 seconfl-feet).

1913; 1915-1920: Maximum discharge recorded, 30,800 second-feet March 28, 

1916; minimum stage, 1.29 feet September 8, 1919 (discharge, 26 second-feet, by 

current-meter measurement).

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

June 1, 1903. Natural minimum discharge at this station, probably 25 secondfeet or less.

ICE. Stage-discharge relation seriously affected by ice.

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

rating curve used during period; well defined between 20 and 35,000 second-feet. 

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

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

discharge. Open-water records excellent except for periods of low stage January 

24, 1916, to July 17, 1919, for which they are only fair on account of uncertain 

error in gage readings caused by use of corroded iron chain; winter records good.

GAGE. Vertical staff gage attached to middle pile of left bent of bridge; read by E. D. 

Burchard.

DISCHARGE MEASUREMENTS. Made from Chicago & Northwestern Railroad bridge at 

extreme high stages; at other stages from footbridge to which gage is attached or 

by wading.

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

water. Left bank high; right bank subject to overflow at stages above 7 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during period May 27, 19J9, to 

September 30, 1920, 8.51 feet at 7.20 p. m. October 4, 1919 (discharge, 2,21<? 

second-feet); minimum discharge, no flow, August 28 to September 17, 1919.

Maximum stage in recent years, about 14.5 feet June 4,1918 (discharge, about 

6,900 second-feet). The creek is dry for a short period nearly every summer.

BsjSi-^ Stage-discharge relation, seriously affected by- iee.

AccuRACY.-^-Stage-diseharge relation changed below gage height 2.9 feet (discharge, 

230 second-feet) by ice jam of March, 1920; seriously affected by ice. Two well 

defined rating curves used, one applicable May 27, 1919, to March 12, 1$2Q, and 

the other, a revision of the former curve, applicable March 13 to September 30, 

1920. Gage read to hundredths twice daily, or oftener during high water. Daily 

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

as indicated in footnote to tables of daily discharge. Open-water records exc.ellen.fi; 

winter records good.

DES MOINES RIVER AT OTTUMWA, IOWA.

LOCATION. At Market Street bridge, Ottumwa, Wapello County. No large tributary

within several miles up or down stream. 

DRAINAGE AREA. 13,200 square miles (measured on map issued by United States

Geological Survey; scale 1 to 500,000). 

RECORDS AVAILABLE. March 28, 1917, to September 30, 1920. Fragmentary bighwater observations were obtained 1902 to 1916. 

GAGE. Chain gage attached to downstream handrail of bridge; read by Henry Eilers.

Staff gage painted on northeast face of north pier used prior to August 2, 1917. x
MISSISSIPPI BIVER 227

. Made irom Vine Street bridge, j&out 1,500Je«t below 

gage or by wading.

CHANNEL AND CONTROL, Channel forms control; practically permanent 

EXTREMES OF PISC&MIOE. Maximum stage recorded during year ending September

80. X919, 14,2 feet May 7 (discharge, 43,200 second-feet); minimum stage, 1.40 

feet October 9 and 10 and September 15-18 (discharge, 525 second-feft).

Maximum sto^o recorded during year finding SepJe#Jbe| 3$, 3^20^ 12.3 Jpet 

March 26 (discharge, S4,700 second-feet); minimum «rt»ge, 2,2 feet October30 

(discharge, 1,460 second-feet); minimum flew probably occurred during winter.

1917-1920: Maximum stage recorded, 16.& feet June 1J, 1917 (discharge, 58,700' 

second-feet); minimum stage, 1.2 feet, to surface of ice, on several days during 

December 1917 (discharge, estimated somewhat less t&aa $30 second-feet).

Maximum discharge since 1850 and probably in the last century occurred May

81. 1903, and exceeded 100,000 second-feet.

ICE. Stage-discharge relation affected by ice during extremely cold weather; observations are discontinued when serious ice conditions prevail.

REGULATION. Operation of power plant a short distance above gage probably causes 

some diurnal fluctuation at low stages.

ACCURACY. Stage-discharge relation changed during break-up of ice i# March, 1910; 

slightly affected by ice in 1910, and seriously affected by ice ia 1920. Two fairly 

well defined rating curves used, applicable respectively, October 1, 1918, to 

December 2, 1919, and March 13 to September 30, 1920. Gage read to tenths 

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

table except for periods indicated in footnote to tables of daily discharge. Openwater records good; winter records fair,

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

ILLINOIS RIVER AT MORRIS, ILL.

LOCATION. In sec. 9, T. 33 N., R. 7 E. third principal meridian, alt 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.

RECORJ&S AVAILABLE. October 1, 1919, to September 30, 1920. January 1, 1903, to 

December 14, 1904, records were obtained at a station near Minooka.

jjtAOE. Chain gage attached to highway bridge; installed March 1, 1916, by United 

States Weather Bureau; read by employee of United States Weather Bureau.

I A staff gage at practically the same site and datum was read once daily under

j the direction of United States Engineer Corps, December 10,1899, to November 

30,1900, and April 20, 1903, to December 11,1904.

DISCHARGE MEASUREMENTS. Made from highway bridge.

CHANNEL AND CONTROL. Bed composed of sand. Dam at Marseilles, 16 miles below 

gage, forms control; permanent.

EXTREMES OF DISCHARGE --Maximum stage recorded during year, 17.8 feet April 21 

(discharge, 48,000 second-feet); minimum stage, 5.2 feet August 9 (discharge, 7,600 

second-feet). 

A discharge of 67,800 second-feet was recorded at station near Minooka on

I March 26, 1904; the stage at Morris at 7 a. m. on that date was 20.45 feet.

^.EfiULATioN. Flow at this station includes the water diverted from Lake Michigan 

through the Chicago Drainage canal. Operation of power plants at Ldckport 

and Joliet causes a considerable diurnal fluctuation at low and medium stages.

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

ice. Rating curve well defined between 10,000 and 30,000 second-feet and fairly 

well defined beyond these limits. Gage read to tenths once daily. Daily discharge ascertained by applying daily gage height to rating table except for period 

December 10 to March 5, during which stage-discharge relation was affected by 

ice, for which it was ascertained by comparison with combined flow at stations on 

Des Plaines River at Joliet and Kankakee River at Custer Park. Records fair. 

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

the present gage was reached.

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 except as affected by ice. 

Rating curve well defined between 10,000 and 50,000 second-feet and fairly well 

defined beyond these limits. Gage read to half-tenths once daily. Daily discharge ascertained by applying daily gage height to rating table except for 

periods, January 1-31, 1919, and December ll,j 1919, to .March 5, 1920, during 

which stage-discharge relation was affected by ice, for which it was ascertained by 

means of gage heights and comparison with flow at adjacent stations. Openwater records good; winter records poor.

ACCURACY. Stage-discharge relation changed following the high water of April and 

May, 1920; slightly affected by ice during 1919; seriously affected by ice during 

1920. Two rating curves used, both fairly well defined below, 2,500 seeond-feet 

and poorly defined above that point; applicable respectively, October 1, 1918, 

to May 31, 1920, and June 1 to September 30, 1920. Gage read to hundredths 

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

table except for periods January 1-20,1919, and December 10, 1919, to March 

11, 1920, during which stage-discharge relation was affected by ice for which it 

was ascertained by means of gage heights, observer's notes, and weather records. 

Indirect method for shifting control used June 1-30, 1920, Open-water records 

fair except for high stages for which they are subject to error; winter records poor.

No discharge measurements were made at this station during year ending September 

30, 1920.

NOTE. No overflow daring 1917. No record of overflow was obtained during 1920, although, overflow probably occurred on about 15 days during March.

\ 

ACCURACY. Stage-discharge relation permanent except as affected by ice during 1920.

Bating curve well defined below 5,500 second-feet; extended above that point. 

*Gage read to half-tenths or hundredths once daily. Daily discharge ascertained 

by applying daily gage height to rating table except fordays when gage was- not react 

for which it was interpolated, and except for period December 5-, 1919, to Maceh 3. 

1920, during which stage-discharge relation was affected by ice, for, whichmeaa discharge was ascertained by means of gage heights, observer/8 notes, and weatherrecords. Open-water records-good except those- for v*ry low stages which arefaiej 

winter records fair.

Published results for discharge ia second-feet per square mile and run-off in 

inches for months in which high stages occurred during the period oi 19-15 to. 191& 

are incorrect, owing to fact that overflow- into Chicago Drainage- caaal was. not 

considered in making: tfce ©omp*rtations. Se# under '' Diversions.''

No discharge measurements were made at this station during-the year ending September 30, 1920.

UPPER MISSISSIPPI BJVEB BASI3ST.

BJVEB AT ALGQWIUpr, ILL.

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

Street bridge in Algonquin, McHenry County, 100 feet above Public Service Co. 'a

daia, and 500 feet above Crystal Lake outlet. 

EECOKBS AVAILABLE. October 1, 1915, to September 30, 1920. 

DRAINAGE AREA. 1,340 square miles (measured on map issued by United States

Geological Survey; scale, 1 to 500,000). 

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

Pedersen. 

CHANNEL AND CONTROL. Control is a concrete dam about 100 feet below gage; repaired during August, 1919; practically permanent. 

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

dam. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September

30, 1919, 4.0 feet at 5.30 p. m. March 21 (discharge, 4,800 second-feet); minimum

discharge, 117 second-feet August 22. 

Maximum stage recorded during year ending September 30, 1920, 4.2 feet at 7

a. m. and 6 p. m. March 30 (discharge, 5,050 second-feet); minimum stage, 1.02

feet June 13 (discharge, 215 second-fee*). 

1916-1920: Maximum stage recorded, 5.3 feet March 31, 1916 (discharge, 7,12d

second-feet) ; minimum stage, 0.59 foot August 31, 1918 (discharge, 67 secondrfeet). 

REGULATION. Water is diverted at dam below gage to operate a grist mill, which run*

on an average of about 4 hours a day, except Sundays, during September to March.

inclusive, and one day a week during the remainder of year. Effect of operation

is appreciable at gage at low stages only and mill headgates are closed when gage

readings or discharge measurements are made. 

ACCURACY. Stage-discharge relation changed by repairs to dam during August, 1919;

temporarily changed during repairs to mill during later part of July, 1919; not

affected by ice. Three fairly well defined rating curves used, applicable respectively, October 1, 1918, to July 14, 1919; July 15 to August 3, 1919, and August 18,

1919, to September 36, 1920. Gage read to hundreidths twice daily. Daily digcharge ascertained by applying daily gage height to rating table except as indicated in footnote to tables of daily discharge. Records good except those obtained during repairs to mill and dam, which are fair.

No discharge measurements were made at this station during year ending Septenv 

bar 30, 1920.

REGULATION. Slight diurnal fluctuation is caused by operation of power plants at 

and above Aurora.

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

curve well defined above and fairly well defined below 1,000 second-feet. Gage 

read to hundredths twice daily. Daily discharge ascertained by applying mean 

daily gage height to rating table except for periods January 2-24, February 8-12, 

1919, and December 10, 1919, to March 3, 1920, during which stage-discharge 

relation, was affected by ice, for which mean discharge was ascertained by means 

of gage heights, observer's notes, and weather records. Open-water records good; 

winter records poor.

No discharge measurements were made at this station during year ending September 

SO, 1920.

LOCATION. In sec. 1, T. 30 N., R. 3 E. third principal meridian, at highway bridge,

known as bridge No. 3, 1£ miles south of Streator, La Salle County, and 100 feet

below Santa Fe Railway bridge. 

DRAINAGE AREA. 1,080 square miles. 

RECORDS AVAILABLE. July 27,1914, to September 30, 1920. 

GAGE. Chain gage attached to highway bridge; read by Floyd Leslie. 

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

CHANNEL AND CONTROL. Bed composed of gravel and rocks; probably permanent. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September

30,1919, 12.95 feet at 4 p. m. March 17 (discharge, 6,830 second-feet); minimum

discharge, 0.1 second-foot August 11, 12, 15, and 16. 

Maximum stage recorded during year ending September 30, 1920, 22.9 feet at

noon April 20 (discharge, 16,500 second-feet); minimum discharge, no flow,

August 25-28 and September 16-30. 

1914-1920: Maximum stage recorded, 22.9 feet April 20,1920 (discharge, 16,500

second-feet); minimum discharge, no flow, August 25-28 and September 16-30,

1920. 

ACCURACY. Stage-discharge relation changed after high water of April and May,

1920; seriously affected by ice. Two rating curves used, both fairly well defined

below 12,000 second-feet, applicable respectively, October 1, 1918, to May 31,

1920, and June 1 to September 30, 1920. Gage read to hundredths once daily.

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

as indicated in footnote to tables of daily discharge. Records good except for 

> periods of extremely low water and periods of ice effect, for which they are poor.

No discharge measurements were made at this station during year ending September 30, 1920.

SPOON RIVER AT SEVILLE, ILL.

LOCATION. In sec. 24, T. 6 N., R. 1 E. fourth principal meridian, at Toledo, Peoria 

& Western Railway bridge, a quarter of a mile east of railway station at Seville, 

Pulton County.

DRAINAGE AREA. 1,600 square 'miles.

RECORDS AVAILABLE. July 24, 1914, to September 30, 1920.

XJAGE. Chain gage attached to bridge; read by R. M. Boales.

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

Measurements made during rapidly changing stages are corrected for change in 

stage by method described in Water-Supply Paper 375.

CHANNEL AND CONTROL. A loose rock dam, aPbout 2 miles downstream from gage, 

used to create a reservoir for the pumping station of the Toledo, Peoria & Western 

Railway, forms control for medium stages; iat other stages control is composed of 

sand and clay and fa somewhat shifting. Dam was removed August, 1918, ant 

replaced August,
UPPBS MISSISSIPPI BIVEB BASIK,

EXT&BKKS OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 17.4 feet June 4 (discharge, 9,600 second-feet); minimum discharge, 

42 second-feet September 13 (determined by current-meter measurement).

Maximum stage recorded during year ending September 30, 1920, 19.4 feet 

March 12 (discharge not determined because of backwater from ice); maximum 

jpen-water stage recorded, 18.7 feet April 22 (discharge, 11,000 second-feet)', 

minimum stage, 2.36 feet September 6 and 10 (discharge, 27 second-feet).

1914-1920: Maximum'stage recorded, 26.0 feet January 23, 1916 (discharge not 

determined because of backwater from ice); maximum open-water stage recorded, 

23.0 feet January 24, 1916 (discharge, 17,800 second-feet); minimum stage, 1.35 

feet July 31 and August 27-29, 1914 (discharge, 3.8 second-feet).

ACCURACY. Stage-discharge relation changed slightly by high water of January, 

1916, September, 1917, and May, 1920, and also by removal and rebuilding of 

dam 2 miles downstream during period noted above (see under "Channel and 

control"); seriously affected by ice. Four rating curves used, all fairly well 

defined below 10,000 second-feet, applicable, respectively, July 24, 1914, to 

January 20, 1916, and September 11, 1917, to August 25, 1918, and August J.6, 

1919, to May 31,1920; January 21,1916, to September 10,1917; August 26,1918, to 

August 15,1919; June 1 to September 30,1920. Gage read to quarter-tenths once 

daily prior to September 30, 1915, and thereafter to hundredths once daily. 

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

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

winter records poor.

No discharge measurements were made at this station during the year ending September 30, 1920.

LOCATION. In southeast corner of SW. i sec. 9, T. 16 N., R. 4 W. third principal 

meridian, at Wabash Railroad bridge a quarter of a mile west of Riverton, Sangamon County, and 2£ miles below mouth of South Fork.

DRAINAGE AEEA. 2,560 square miles.

RECORDS AVAILABLE. February 13, 1908, to December 31, 1912; August 7, 1914, to 

September 30,1920.

&A.GE. Chain gage attached to bridge; read by J. J. Washburn.

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

CHANNEL AND CONTROL. Control composed of fine gravel; shifting. Measuring 

section is at a pool.

EXTREMES of DISCHARGE. Maximum stage recorded during year ending September 30, 1939, 23.37 feet at 4.30 p. m. June 29 (discharge, 11,100 second-feet); 

minimum stage, 7.42 feet at 4.30 p. in. September 16 (discharge, 90 second-feet). 

Maximum stage recorded during year ending September 30, 1920, 25.07 feet 

May 14 (discharge, 14,200 second-feet); minimum stage, 7.09 feet August 7 (discharge, 12 second-feet).

1908-1912 and 1914-1920: Maximum stage recorded, 27.8 feet February 3, 

1916 (discharge, 20,800 second-feet); minimum stage, 6.9 feet October 3-16, 

1914 (discharge, 3 second-feet).

Flood of 1883, reached a stage of about 32 feet on the present gage, and that of 

1875 is said to have been one-half foot lower (discharge not determined).

ACCURACY. Stage-discharge relation changed during high water of latter part of 

June, 1919, and again the latter part of March, 1920; affected by ice during winter 

1919-20. Three rating curves used; the first and second applicable respectively, 

October 1, 1918, to June 30, 1919, and July 1, 1919, to March 28, 1920, are both 

fairly well defined above 30 second-feet and poorly defined below that point; 

the third, applicable March 29 to September 30, 1920, is fairly well defined between 30 and 4,000 second-feet, poorly defined below 30 second-feet, and extended 

above 4,000 second-feet on basis of shape of previous curve. Gage read to hundredths once daily. Daily discharge ascertained by applying daily gage height 

to rating table except as indicated in footnote to tables of daily discharge. Openwater records good; winter records poor.

SAJTGAMON RIVER NEAR OAKFORD, ILL.

LOCATION. In sec. 6, T. 19 N., R. 7 W. third principal meridian, at highway bridge 3 

miles northeast of Oakford, Menard County, 2J miles above Chicago, Peoria & 

St. Louis Railway bridge, and 1£ miles above mouth of Crane Creek.

DRAINAGE AREA. 5,000 square miles.

RECORDS AVAILABLE. October 26, 1909, to June 30, 1911; December 10, 1911, to 

March 31, 1912; and August 25, 1914, to June 11, 1919, when station was discontinued.

GAGE. Chain gage attached to bridge; read by Henry Chesser.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Bed composed of sand and fine gravel; shifting. The river 

for some distance above and below station has been dredged and straightened, 

thus increasing the slope considerably and disturbing the regimen of flow.

EXTREMES OF DISCHARGE. Maximum stage recorded during period, 13.15 feet at 4.30 

p. m. March 21 (discharge, 11,900 second-feet); minimum stage, 1.25 feet at 4.30 

p. m. October 20 (discharge, 173 second-feet).

.' 1909-1912 and 1914-1919: Maximum discharge recorded, 33,300 second-feet 

June 8 and 9,1917 (determined from extension of rating curve); minimum discharge recorded, 85 second-feet August 30 and 31, November 28, and December 

2, 1914.

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

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

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

as indicated in footnote to tables of daily discharge. Open-water records good; 

winter records poor.

trPPER MISSISSIPPI EIVSJR BASIN. 271

SOUTH FOAK 07 SANOAMON RIVER AT POWER PLANT, WEAK TAYLORVHJUE, BUL.

LOCATION. In sec. 14, T. 13 N., E. 3 W., at Chicago & Illinois Midland Railroad 

bridge, 6 miles northwest of Taylorville, Christian County, 500 feet east of power 

plant of Central Illinois Public Service Co., 5 miles below mouth of Bear Creek, 

and 8 miles below station formerly maintained at Wabash Railroad bridge,

DBATNAGB ABBA. 510 square miles (measured on map issued by United States 

Geological Survey; scale, 1 to 500,000).

UNCORDS AVAILABLE. May 18, 1917, to September 30, 1920.

<JAGE. Chain gage attached to bridge; read by employees of Central Illinois Public 

Service Co.

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

CHANNEL AND CONTROL. Bed composed of soft mud; likely to shift.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30,1919,16.11 feet June 26 and 27 (discharge, 2,150 second-feet); minimum stage,, 

3.37 feet September 11,12, and 14 (discharge, 1.0 second-foot).

Maximum stage recorded during year ending September 30, 1920, 19.5 feet 

May 19 (discharge, 4,800 second-feet); minimum stage, 3.40 feet August 11 and 12 

and September 26 (discharge, 3.0 second-feet).

1917-1920: Maximum stage recorded, 26.6 feet June 6, 1917 (discharge, 10,400 

second-feet); minimum stage, 3.37 feet September 11,12, and 14,1919 (discharge, 

1.0 second-foot); discharge during latter part of January, 1918, probably somewhat 

less than 1,0 second-foot.

A stage of about 27.3 feet on present gage is said to have been reached January 

31, 1916 (discharge, 11,300 second-feet).

DIVERSIONS. On an average, about half a second-foot- of water is used for boiler 

feed and other purposes at the power plant.

ACCURACY. Low-water stage-discharge relation changed slightly during August, 1919, 

and May, 1920; high-water stage-discharge relation changed considerably during 

fall of 1919 on account of replacing pile-trestle approach to railway bridge with 

through girder spans, and by clearing at approaches. Stage-discharge relation 

seriously affected by ice for short periods during winter and by a log and drift jam 

below gage during period February to May, 1920. Three fairly well defined 

rating curves used, applicable respectively, October 1, 1918, to August 19,1919; 

September 20 to December 31, 1919; January 1 to September 30, 1920. Gage 

read to hundredths once daily. Daily discharge ascertained by applying daily 

gage height to rating table except as indicated in footnote to tables of daily discharge. Open-water records fair except for period during which log and drift 

jam occurred for which they are poor; winter records poor.

SURFACE WATER SUPPLY, 1919^-19aQ, PABT V.

KASKASKtA RIVER AT NEW ATHENS, ILL.

LOCATION. In W. J NE. i sec. 28, T. 2 S., R. 7 W. third principal meridian, at Illinois 

Central Railroad bridge 600 feet north of railroad station at New Athens, St. 

Glair County, 1 mile below mouth of Silver Creek, and 3 miles above mouth of 

Lively Creek.

DRAINAGE AREA. 5,220 square miles.

UECORDS AVAILABLE. January 23, 1907, to December 31, 1912; June 22, 1914, to 

September 30,1920. Gage height of river was taken on Wednesday and Thursday 

mornings from January 23, 1907, to October 28, 1909, by C. J. von Roth Roffy 

for the New Athens Journal, in which they are published. These heights have 

been reduced to the present datum; maximum error probably not more than 0.4 

foot, decreasing with increase of stage. Record is authentic.

 GAGE. Chain gage attached to bridge, installed November 1, 1909; read by Henry 

Hoffman.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge to which gage is 

attached or from highway bridge about 500 feet downstream.

OHANNEL AND ^CONTROL. Bed composed of sand and gravel; may shift.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 24.0 feet at noon June 10 (stage-discharge relation affected by backwater 

from Mississippi River); maximum discharge, 12,700 second-feet March 25 and 26; 

minimum stage recorded, 2.85 feet September 16-20 (discharge, 162 second-feet). 

Maximum stage recorded during year ending September 30, 1920, 27.6 feet at 

noon November 1 (discharge, 28,000 second-feet); minimum stage, 2.89 feet 

October 23 (discharge, 172 second-feet).

1907-1912; 1914-1920: Maximum stage recorded, 35.7 feet August 26, 1915 

(discharge, 63,100 second-feet); minimum stage, 2.08 feet August 10, 1914 (discharge, 102 second-feet).

ACCURACY. Stage-discharge relation changed during high water of November, 1919, 

and again during high water of March, 1920; not seriously affected by ice during 

winter; affected by backwater from Mississippi River at various times. Three 

poorly defined rating curves used, applicable respectively, October 1, 1918, to 

November 17, 1919, November 18, 1919, to March 15, 1920, and March 16 to 

September 30, 1920. Indirect method for shifting control used November 2-17, 

1919, and March 16-29, 1920. Gage read to hundredths once daily. Daily discharge ascertained by applying daily gage height to rating table except as indicated 

in footnote to tables of daily discharge. Records poor.

AootritACY. Stage-discharge relation changed during high tratw ol December, IMS, 

and again during March, 1926; not affected by ice! Eating curve used October 

1, 1918, to Marci 20, 1920, poorly denned below 260 second-feet, and fairly well 

defined above that point; curve used March 21 to September 30, 1920, fairly well 

defined throughout. Gage read to hundr«dths once daily. Daily discharge 

ascertained by applying daily gage height to rating table except jfof days when 

gage was not read for which it was ascertained by interpolation. Records fair.

UPPER MISSISSIPPI EIVEB BASIN. 281

BIG MUDDY BITER AT MURPHYSBORO, ILL.

LOCATION. In SW. £ sec. 8, T. 9 S., R. 2 W., at lower highway bridge on South 

Twentieth Street, Murphysboro, Jackson County, a quarter of a mile below mouth 

of Louis Creek.

DRAINAGE AREA. 2,170 square miles.

RECORDS AVAILABLE. December 6,1916, to September 30, 1920. »

GAGE. Chain gage attached to bridge; read by Clarence Jacobs.

CHANNEL AND CONTROL. Bed composed of heavy clay; likely to shift.

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

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 28.05 feet at 5 p. m. December 19 (discharge, 10,900 second-feet); minimum stage, 1.57 feet August 11-13 (discharge, 3.0 second-feet).'

Maximum stage recorded during year ending September 30, 1920, 34.0 feet at 

7 a. m. November 5 (discharge not determined because of backwater from Missis* 

sippi River); maximum stage recorded during periods of no backwater effect,. 

24.0 feet March 13 (discharge, 8,690 second-feet); minimum stage, 1.80 feet October 

6 and 7 (discharge, 14 second-feet).

1917-1920: Maximum discharge recorded, 15,600 second-feet January 10, 1917;

minimum stage recorded, 1.57 feet August 11-13,1919 (discharge, 3.0 second-feet).

The highest known stage of this river occurred about February 2, 1916, when a

height of 39.6 feet on the present gage was reached (discharge, from extension of

rating curve, 28,000 second-feet).

ACCURACY. Stage-discharge relation changed slightly during high water of June and 

July, 1920; affected by backwater from Mississippi River whenever height on 

United States Weather Bureau gage at Chester, 111., is above about 10 feet; not 

affected by ice. One rating curve, fairly well defined between 5 and 12,000- 

second-feet, used; indirect method for shifting control used August 12 to September 30, 1920. Gage read to hundredths once daily. Daily discharge ascertained 

by applying daily gage height to rating table except as indicated in footnote to 

tables of daily discharge. Records fair.
