SURFACE WATER SUPPLY OF MISSOURI RIVER 

BASK, 1919-1920.

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 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 best methods of utilizing the water resources.

Annual appropriation 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 pages 13-15.

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 

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-off in inches, acre-feet, and millions of cubic feet. 

The principal terms used in this series of reports are second-feet, 

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

may be defined as follows:

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

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

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

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

unit from which others are computed.

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

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

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

regards time and area.

"Run-roff 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 com- i 

monly used in connection with storage for irrigation.

The following terms not in common use are here defined:

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

of gage height to discharge."

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

stream 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 given 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 OP DATA.

The data presented in this report cover the biennium 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 

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

from precipitation within that year.

The base data collected at gaging stations consist of records of 

stage, measurements of discharge, and general information used to 

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
12 SURFACE WATER SUPPLY, 1919-1920, PART VI.

day. If such stations are equipped with water-stage recorders the 

mean daily discharge may be obtained by averaging discharge at 

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

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

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

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

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

and the corresponding discharge was consequently larger than given 

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

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

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

flow computations recorded in the remain columns, which are 

defined on page 10, are based. *

ACCURACY OF FIELD DATA AND COMPUTED RESULTS.

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

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

observation of stage, measurements of flow, and interpretation of 

records.

A paragraph in the description of the station or footnotes added to 

the tables gives information regarding the (1) permanence of the stagedischarge 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 run-off in inches 

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

information concerning water diverted for irrigation or other use, 

or by inability to interpret the effect of artificial regulation of the 

flow of the river above the station. "Second-feet per square mile" 

and "Run-off in inches" are therefore not computed if such errors 

appear probable. The computations are also omitted for stations 

on streams draining areas in which the annual rainfall is less than

20 inches. All figures representing "second-feet per square mile" 

and "run-off in inches" previously published by the Survey should 

be used with caution because of possible inherent sources of error 

not known to the Survey.

Many gaging stations on streams in the irrigated sections of the 

United States are situated above most of the diversions from those 

streams, and the discharge recorded does not show the water supply 

available for further development, as prior appropriations below the 

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

prior appropriations, a paragraph on diversions is presented in each 

station description. The figures given can not be considered exact, 

but represent the best information available.

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

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

estimates; the tables of daily discharge allow more detailed studies 

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

the observations in each succeeding year may be expected to throw 

new light on data previously published.

COOPERATION.

Much of the work in Montana has been carried on under cooperative agreement with the United States Reclamation Service, the 

work being done by the Geological Survey and the expense borne by 

the Reclamation Service. The legislature of the State of Montana 

made an appropriation for stream-gaging work, which was expended 

by the State engineer, as provided in the act, in accordance with 

paragraph 3, section 2244, of the Revised Codes of 1907 of the State 

of Montana, which reads as follows:

The State engineer shall become conversant with the waterways of the State and the 

needs of the State as to irrigation matters, shall make, or cause to be made, measurements and calculations of the ordinary and flood discharge of streams, cooperating in 

this work as much as possible with the United States Geological Survey and the Montana Experiment Station; such measurements to be made on streams in order of their 

importance, provided that measurements already made, if deemed reliable, may be 

adopted.

This fund was expended largely on work in connection with the 

several Carey projects in Montana and in computing data on waterright filings and adjudications. A State hydrographer was employed 

who worked directly with the Geological Survey.

The expense of work on the Crow Reservation in Montana was 

borne by the office of Indian Affairs. Jacqueth-Gerharz Engineering 

Co., Great Falls, Mont., cooperated in maintaining the station on 

Crow Creek near Radersburg, Mont.

Officials of the Yellowstone National Park have furnished gage 

readings and paid for part of the expense of work done in the park.

All stations in Wyoming were maintained in cooperation with the 

State through Mr. F. C. Emerson, State engineer. The commissioner
14 SURFACE WATER SUPPLY, 1919-1920, PART VI.

of public lands, Mr. A. Baker, paid the gage observer on Clark Fork 

near Clark, Wyo.

The United States Reclamation Service paid for the maintenance 

of stations on North Platte River above Pathfinder, Wyo., Sage 

Creek above Pathfinder, Dinwoody Creek near Lenore, Wyo., and 

Bull Lake Creek near Lenore, Wyo., and also furnished complete 

records for certain stations as acknowledged in connection with 

descriptions of those stations.

The United States Forest Service furnished gage heights for Big 

Creek near Big Creek, Wyo., Middle Fork of Popo Agie River near 

Lander, Wyo., and Tongue River near Dayton, Wyo.

The Laramie Water Co. furnished gage heights and provided the 

transportation necessary to obtain data for the stations on Laramie 

River and Pioneer canal near Woods, Wyo. The Laramie Water Co. 

and the Wyoming Development Co. each paid half of the cost of 

installing the new gage and cable on Laramie River at Two Rivers, 

Wyo.

The Hawk Springs Development Co. furnished gage heights and 

provided transportation necessary^to obtain data for the station on 

Horse Creek near Lagrange, Wyo. The L. Z. Leiter estate, through 

J. C. Beebe, manager, furnished gage heights for Piney Creek at 

Ucross, and provided transportation to a number of stations in the 

vicinity. The Douglas Reservoirs Co. installed the station on La 

Prele Creek near Douglas, Wyo., furnished gage heights and some 

discharge measurements, and provided transportation to the station. 

Mr. Fred Firnekas, water commissioner, furnished data relating to 

diversion of water from the headwaters of Clear Creek. The Wyoming Irrigation Co. furnished the gage heights for Shell Creek at 

Shell, Wyo. The State engineer of Colorado paid the gage observer 

on Laramie River near Jelm, Wyo. The North Laramie Land Co. 

furnished gage heights for North Laramie River near Wheatland, 

Wyo.

In Colorado the State engineer, Mr. A. J. McCune, paid the gage 

observers at the stations on the South Platte at South Platte, and 

on the North Fork of the South Platte at South Platte. The city 

of Denver furnished records of South Platte River at the intake in 

Platte Canyon. The city engineer of Loveland furnished the field 

data for Big Thompson Creek near Drake, and provided transportation to the station when measurements were made. The city engineer of Boulder furnished the records for North Boulder Creek at 

Silver Lake. The Farmers Reservoir & Irrigation Co. reinstalled 

the station on Clear Creek near Golden and furnished the gage heights.

In South Dakota the State engineer paid the observer's salary at 

the station on Cheyenne River near Hot Springs.

The work in Iowa has been carried on under cooperative agreement 

with the State Highway Commission, with Mr. R. W. Clyde, drainage

engineer of the commission, in charge. His part-time salary and 

expenses and the observer's salary were paid by the State Highway 

Commission.

In Kansas the work was done in cooperation with the Kansas 

Water Commission, H. A. Rice, secretary, under terms of the water 

commission act of the legislature of 1917 (chapter 172, session laws 

of Kansas, 1917, p. 218). The cooperative agreement with the 

Kansas Water Commission was entered into May 11, 1917, for an 

investigation of the water resources of Kansas; district headquarters 

were established June 1, 1917, in the Federal building, Topeka, Kans. 

These investigations in Kansas were assisted through the cooperation 

of the United States Weather Bureau and several local organizations. 

The United States Weather Bureau cooperated in the maintenance 

of a long-distance water-stage recorder at the gaging station on 

Kansas River at Topeka. The receiving instrument, located in the 

Weather Bureau office, S. D. Flora, meteorologist in charge, formed 

an integral part of the Weather Bureau's flood forecast service for 

the Kansas Valley. Franklin County and the city of Ottawa, Kans., 

cooperated in the investigations in the Osage River basin by furnishing some of the materials used in the construction of the reinforced 

concrete well and shelter for the water-stage recorder at the gaging 

station on Osage River near Ottawa, Kans.; this station was completed in the fall of 1918.

DIVISION OF WORK.

Data for stations in the upper Missouri River basin in Montana 

and North Dakota were collected and prepared for publication under 

the direction of W. A. Lamb, district engineer, who was assisted by 

A. H. Tuttle, E. F. Chandler, R. F. Edwards, H. S. Price, and L. H. 

Hershner, and by G. H. Ellis, State hydrographer of Montana.

Data for the Missouri River drainage basin in Colorado and Wyoming were collected and prepared for publication under the direction 

of Robert Follansbee, district engineer, assisted by P. V. Hodges, 

J. B. Spiegel, and Miss Esther M. Dye. The field work in South 

Dakota was carried on under the supervision of Robert Follansbee.

Data for two stations in Yellowstone National Park were collected 

and prepared for publication under the direction of C. G. Paulsen, 

district engineer, assisted by T. R. Newell, E. C. Howard, A. G. 

Fiedler, L. L. Bryan, and Miss E. H. Haugse.

Data for stations in the Missouri River basin in Iowa were collected 

and prepared for publication under the direction of W. G. Hoyt, 

district engineer, assisted by E. D. Burchard and H. C. Beckman.

Data for stations in the Kansas and Osage River basins in Kansas 

were collected and prepared for publication by R. C. Rice, district 

engineer, assisted by A. K. Gowans, E. L. Grant, Miss Maude Ten 

Eyck, and Mrs. R. C. Rice.
16 SURFACE WATER SUPPLY, 1919-1920, PART VI.

GAGING STATION RECORDS.

MISSOURI RIVER PROPER. 

BEAVERHEAD RIVER AT BARRATTS, MONT.

LOCATION. In SW. | SW. i sec. 20, T. 8 S., R. 9 W., on highway bridge at point 

where highway crosses railroad and where both highway and railroad bridges 

cross river, 1 mile above Barratts, in Beaverhead County, 2 miles below mouth 

of Grasshopper Creek, and 10 miles southwest of Dillon.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. August 12, 1907, to September 30, 1920.

GAGE. Chain gage on downstream side of bridge; read by T. Masuno. Before 

June 22, 1908, a staff gage was used. Datum of chain gage same as that of staff 

gage.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Banks high, covered with brush, and not subject to overflow. Stream bed clean and rocky. Two channels at low and medium stages, 

caused by an old pier; sudden changes unlikely.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 2.30 feet April 28 (discharge, 938 second-feet); minimum-stage, 0.50 

foot July 28, 29, August 19-31, and September 1,10-17 (discharge, 106 second-feet). 

Maximum stage recorded during the year ending September 30, 1920, 2.69 

feet May 17 (discharge, 1,130 second-feet); minimum stage, 0.60 foot October 

1-9 (discharge, 135 second-feet).

1907-1920: Maximum stage recorded, 6.0 feet June 19 and 20, 1908 (discharge, 

3,640 second-feet); minimum stage recorded, 0.50 foot July 28, 29, August 19-31, 

September 1, 10-17, 1919 (discharge, 106 second-feet).

ICE. Observer did not report ice during the year, and comparison of gage heights 

with thermograph indicates that open-channel conditions prevailed throughout.

DIVERSIONS. Numerous diversions are made above the station. Water rights 

aggregating 85,866 inches of water are decreed from Lima on Red Rock Creek 

to a point 10 miles above Twin Bridges. The three largest canals diverting 

below the station are Canyon Creek canal, appropriating 6,000 inches; Union 

canal, appropriating 4,000 inches; and Beaverhead canal, diverting just north 

of Dillon, appropriating 5,000 inches. The Union Electric Co. of Dillon has 

a canal with a carrying capacity of 6,000 inches.

REGULATION. Operation of the dam used to store flood waters of Red Rock Creek 

near Monida has some effect on the flow at this station.

ACCURACY. Control shifted during May and June, 1920. Rating curve used October 

1, 1918, to May 2, 1920, well defined between 170 and 820 second-feet; curve 

used July 1 to September 30, 1920, well defined between 100 and 500 second-feet. 

Gage read to tenths twice daily. Daily discharge ascertained by applying mean 

daily gage height to rating table; shifting-control method used May 3 to June 

30, 1920.

MADISON RIVER BASIN. 

MADISON RIVER NEAR YEIXOWSTONE, MONT.

LOCATION. In sec. 5 (approximately), T. 14 S., R. 6 E. Montana meridian, 250 feet 

upstream from old footbridge at fording place of old Gallatin trail, just north of 

stage road to Yellowstone, in front of Riverside ranger station, and about 4 miles 

east of Yellowstone and west boundary of Yellowstone National Park. Gibbon 

and Firehole rivers unite to form the Madison 8 miles upstream.

DRAINAGE AREA. 410 square miles (measured on topographic maps).

RECORDS AVAILABLE. June 16, 1913, to September 30, 1920.

GAGE. Friez water-stage recorder installed October 20, 1918, on left bank. Prior to 

October 10, 1918, a vertical staff at different datum located on left bank 500 

feet below recording gage was used exclusively. On account of unfavorable 

conditions caused by ice and snow in the vicinity of the recording gage, the staff 

was used December 1, 1918, to May 27, 1919, and November 2, 1919, to June 4, 

1920. Read by park rangers from the Riverside ranger station.

DISCHARGE MEASUREMENTS. High-stage measurements made from cable one-third 

mile below gage, installed September 9, 1917. Previous to this date high-stage 

measurements made from old footbridge 250 feet upstream from gage. Medium 

and low stage measurements made by wading.

CHANNEL AND CONTROL. One channel at all stages. Bed of stream is gravel and 

boulders; somewhat rough; control at recorder and staff gage is different but is 

believed to be permanent. Aquatic growth is present during greater part of 

year and during summer affects the stage-discharge relation.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, from water-stage recorder, 4.35 feet at 11 a. m. May 29 (discharge, 1,110 

second-feet); minimum stage, 3.67 feet at 2 to 10 a. m. July 23 (discharge, 316 

second-feet).

Maximum stage recorded during year ending September 30, 1920, from waterstage recorder, 4.58 feet at noon June 9 (discharge, 1,510 second-feet); minimum 

stage, 1.19 feet January 11-15 and February 10 (discharge, 353 second-feet).

1913-1920: Maximum stage recorded, 2.64 feet (vertical staff) at 6 p. m. June 

10, 1917 (discharge, 1,950 second-feet); minimum stage, July 23, 1919.

ICE. Stage-discharge relation not seriously affected by ice. Temperature of water 

except during extremely cold weather kept above freezing point by numerous 

hot springs and geysers.

DIVERSIONS. None above station.

REGULATION . None.

ACCURACY. Stage-discharge relation practically permanent except for a slight change 

assumed to have occurred October 5,1918, and slight change at site of water-stage recorder which occurred during period when staff gage was used in winter of 1919-20.. 

For records obtained from staff gage a fairly well-defined rating curve was used 

October 1-4, 1918, and a curve well-defined between 350 and 1,500 second-feet 

was used October 10-19, 1918, December 1, 1918, to May 27, 1919, and November 

2, 1919, to June 4, 1920. For records obtained from water-stage recorder rating 

curves well defined between 350 and 800 second-feet were used October 20 to 

November 30, 1918, May 28 to November 1, 1919, and June 5 to September 30, 

1920. Operation of water-stage recorder fairly satisfactory. Staff gage read to 

quarter-tenths once daily; records believed to be reliable. Daily discharge 

ascertained by applying daily gage height to rating table. For period when waterstage recorder was operated the mean daily gage height was obtained by inspection 

of recorder graph. Shifting-control method used October 5-9, 1918. Records 

good for periods when water-stage recorder was in operation; fair for periods when 

records from staff gage were used.

1915-1920: Maximum stage, 4.87 feet at 2 p. m. May 15, 1917 (discharge, 948 

second-feet); minimum stage in 1920.

ICE. Stage-discharge relation affected by ice; gage not read during winter.

DIVERSIONS. Small ditch diverts in summer for water supply of Helena.

REGULATION. Small reservoir of water-supply system of Helena is above the station 

but operation of reservoir has probably little, if any, effect upon the flow past the 

gaging station.

ACCURACY. Stage-discharge relation slightly affected by moss in 1919. Rating 

curves well defined; shifting-control method used August 26 to September 30, 

1919. Operation of water-stage recorder satisfactory except as shown in footnote 

to table of daily discharge. Daily discharge ascertained by applying to rating 

table daily mean gage height obtained by inspection of recorder graph. Records 

good.

ACCURACY. Stage-discharge relation changed slightly during high water in June, 

1920; affected by ice. Rating curve used October 1, 1918, to June 15, 1920, well 

denned between 150 and 9,000 second-feet; curve used June 16 to September 30, 

1920, poorly defined. Gage read once daily to half-tenths. Daily discharge 

ascertained by applying daily gage height to rating table. Records poor for low

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 30, 1919, 5.38 feet at 7.30 p. m. May 29 (discharge, 2,030 second-feet); minimum stage, 2.02 feet September 6, 7, and 8 (discharge, 4.4 second-feet).

1920: Maximum stage recorded during year ending September 30, 1920, 5.48 

feet at 7.30 p. m. May 21 (discharge, 2,150 second-feet); minimum stage, 2.32 feet 

September 13 (discharge, 36 second-feet).

1907-1920: Maximum stage recorded., 8.15 feet June 9,1909 (discharge, 7,600 

second-feet); undoubtedly higher in June, 1908, but gage was washed out and no 

record obtained; minimum stage recorded in 1919.

ICE. Stage-discharge relation practically unaffected by ice.

DIVETRSIONS. Water diverted about 2 miles above gage by ditch which supplies 

about 100 acres on farm at the Holy Family Mission. From May 10 to September 21, 1919, 16,100 acre-feet were diverted, and during 1920, 11,430 acre-feet 

were diverted by United States Reclamation Service above station to irrigate 

lands in vicinity of Seville on Blackfeet Indian Reservation.

REGULATION. Flow regulated by operation of reservoir at Lower Two Medicine Lake.

ACCURACY. Stage-discharge relation changed during March and April, 1919. Rating 

curve used from October 1, 1918, to March 28, 1919, well defined between 60 and 

2,400 second-feet; curve used from April 17, 1919, to September 30, 1920, well defined below 1,000 second-feet; shifting-control method used March 29 to April 16, 

1920. Gage read to hundredths twice daily. Daily discharge ascertained by 

applying daily mean gage height to rating table. Records good.

was used.

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

CHANNEL AND CONTROL. Bed composed of gravel and boulders. Control at gravel

bar 200 feet downstream; shifting. Right bank subject to overflow at extremely

high water. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September

30,1919, 5.58 feet at 8 a. m. May 31 (discharge, 3,890 second-feet); minimum stage,

1.50 feet at 6 p. m. August 20 (discharge, 10 second-feet).

BIRCH CREEK AT SWIFT DAM, NEAR DTTPITSrER, MONT.

LOCATION. At Swift dam, on south boundary of Blackfeet Indian Reservation

Pondera County, 20 miles west of Dupuyer and 34 miles west of Valier. North

and South forks of Birch Creek unite in reservoir above station. 

DRAINAGE AREA. 75 square miles (revised; measured on topographic maps). 

RECORDS AVAILABLE. March 26, 1913, to September 30, 1920. 

GAGE. Vertical iron gage on right bank 800 feet below dam; read by B. P. Parisl.

Prior to July 11, 1915, a vertical wooden staff on right bank, one-fourth mile belo'v

dam was read except from June 5 to July 16, 1913, when temporary gage on left

bank immediately below dam was used to obtain high-water records. Overflow

from spillway is referred to same gage as water-surface elevation in reservoir. 

DISCHARGE MEASUREMENTS. Discharge through valves" measured from footbridge

300 feet above gage or by wading. 

CHANNEL AND CONTROL. Bed composed of coarse gravel and boulders; slightly shif ' -

ing. Control at riffle 100 feet downstream; shifts during high water. Spillway

channel is a rock cut headed by a concrete spillway lip. 

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September

30,1919, 3.83 feet from 7.45 a. m. to 1.30 p. m. June 11 (discharge, 850 second-feet);

minimum stage, 1.40 feet October 2, 1918 (discharge, 1.0 second-foot). 

Maximum stage recorded during year ending September 30,1920, June 16 (coirbined flow, 897 second-feet); minimum stage recorded, 1.40 feet January 2, ro

flow. 

1913-1920: Maximum discharge, 5,275 second-feet at 5 a. m. June 21, 1916; no

flow 6 p. m. January 2 to 6 a. m. January 3. Minimum flow is controlled an-*

maximum partly regulated by valves at dam. 

ICE. Stage-discharge relation affected by ice for short periods. 

DIVERSIONS. Two small ditches, known locally as Cote ditch and Jones ditch, divert

water just below dam and above gage.
MARIAS RIVER BASIN. 59

REGULATION. Dam is used to store flood and winter flow, and during dry periods 

will release no more water than can be handled by canal system of Valier-Montana 

Land & Water Co., in addition to amount required by prior rights. Capacity of 

reservoir is 30,000 acre-feet.

ACCURACY. Outlet channel: Stage-discharge relation shifted during high water in' 

1920. Rating curve used previous to shift, fairly well defined; curve used after 

shift, well defined. Gage read to hundredths twice daily, except when gate 

valves were changed, during which periods it was read from 3 to 6 times. Daily 

discharge through valves ascertained by applying daily mean gage height to 

rating table. Records good.

Spillway channel: Concrete lip of spillway affords permanent control but only 

one measurement has been referred to gage above this crest. Discharge is estimated by engineers of Valier-Montana Land & Water Co. from this measurement 

and from records of other stations on stream. Gage read to hundredths twice 

daily.

COOPERATION. All field data furnished by engineering department of Valier-Montana 

Land & Water Co.; computation of daily and monthly discharge made by United 

States Geological Survey.

years ending Sept. SO, 1919 and 1920.

62 SURFACE WATER SUPPLY, 1919-1920, PART VI.

BIRCH CREEK NEAR~DUPUYER, MONT.

LOCATION. In sec. 28, T. 29 N., R. 8 W., at Kepple'a ranch, half a mile above headgate of B canal of Valier-Montana Land & Water Co., 12 miles northwest of Dupuyer, Pondera County, and 20'miles above mouth of Dupuyer Creek.

DRAINAGE AREA. 110 square miles (revised from topographic maps).

RECORDS AVAILABLE. July 25, 1907, to September 30, 1920.

GAGE. Steel bar driven into bed of stream; also gage in well in bank at same section; 

read by Wade Starleigh.

DISCHARGE MEASUREMENTS. Made by wading or from cable a quarter of a mile 

above gage.

CHANNEL AND CONTROL. Bed composed of gravel. Control is gravel bar about 250 

feet below gage; shifting. Banks are subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 6.0 feet at 6 p. m. June 11 (discharge, 680 second-feet ; minimum stage 

3.02 feet at 8.30 a. m. April 12 (discharge, 5.4 second-feet).

Maximum stage recorded during year ending September 30, 1920, 6.26 feet 

June 15 (discharge, 838 second-feet); minimum discharge estimated, 5.0 secondfeet, January 14-17 and 21-24.

1907-1920: Maximum stage recorded, 10.0 feet June 21, 1916 (discharge estimated, 5,000 second-feet); minimum stage in 1920.

ICE. Discharge relation seriously affected by ice.

DIVERSIONS. Two or three small ditches divert above station.

REGULATION. Flow largely controlled by Swift dam at Birch Creek reservoir having 

capacity of 30,000 acre-feet, located 12 miles upstream.

ACCURACY. Stage-discharge relation shifted each year. Two well defined rating 

curves used during 1919; shifting-control method used from June 21-25. Three 

well defined rating curves used during 1920. Gage read to hundredths once 

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

Records good.

COOPERATION. Gage heights and discharge measurements furnished by engineering 

department of Valier-Montana Land & Water Co. Computations of daily and 

monthly discharge made by United States Geological Survey.

DUPUYER CREEK NEAR VALIER, MONT.

LOCATION. In NE. i NW. i sec. 33, T. 29 N., R. 6 W., at Cowell ranch, 1,000 feet 

above diversion dam at head of D canal from Dupuyer Creek to Lake Frances 

reservoir and outlet of B canal, which diverts water from Birch Creek to Dupuyer 

Creek, 6 miles below mouth of Sheep Creek, and 11 miles southwest of Valier, 

Pondera County, nearest railway point.

DRAINAGE AREA. 111 square miles (measured by Valier-Montana Land & Water Co.).

RECORDS AVAILABLE. July 17, 1912, to September 30, 1920.

GAGE. Vertical steel staff on right bank, 1,000 feet above diversion dam, used since 

June 23, 1916; read by Cecil Carey and others.

DISCHARGE MEASUREMENTS. Made by wading at low stages. High-water measurements made from cable 30 feet below gage or from bridge 5 miles below gage.

CHANNEL AND CONTROL. Bed of stream fine gravel; right bank high and steep; left 

slopes gradually and is overflowed only at flood stage. A bar or ledge that produces a riffle about 400 feet below the gage forms the control at certain stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 3.08 feet at 7.45 p. m. April 1 (discharge, 44 second-feet); no flow September 19.

Maximum stage recorded during the year ending September 30, 1920, 5.60 feet 

at 6 p. m. April 13 (estimated discharge, 1,130 second-feet); minimum discharge, 

0.2 second-foot, October 7.

1912-1920: Maximum stage recorded, 6.5 feet on June 21, 1916, determined by 

level from flood marks (discharge, 2,180 second-feet); no flow September 19, 1919.

ICE. Stage-discharge relation affected by ice. Winter flow computed from currentmeter measurements and observer's daily estimate.

DIVERSIONS. A number of small ditches divert water for irrigation from Dupuye' 

Creek and tributaries; many of the numerous water-right filings have been pe' 

fected by use.

REGULATION. None.
MARIAS RIVER BASEST. 65

ACCURACY. Stage-discharge relation changed during winter of 1919-20; affected by 

ice. Rating curve used for 1919, fairly well defined below 3 second-feet and well 

defined between 3 and 40 second-feet; curve used for 1920 fairly well defined 

between 20 and 280 second-feet. Gage read to hundredths daily (twice during 

periods of rapid change). Daily discharge ascertained by applying gage height 

to rating table; discharge for periods of ice effect determined from current-meter 

measurements and temperature records. Records good.

COOPERATION. Complete data furnished by the Valier-Montana Land & Water Co.

4.00 feet. From July 21 to September 30, 1919', staff gage on right bank 20 feet 

below bridge and at same datum as chain gage was read.

DISCHARGE MEASUREMENTS. Made from highway bridge or by waditig. > :

CHANNEL AND CONTROL. Bed of stream composed of fine gravel and sand; shifts 

frequently. No well-defined control. Banks are overflowed at high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 7.60 feet May 13 (discharge, 686 second-feet); minimum discharge recorded, 4.3 second-feet on March 22.

Maximum stage recorded during year ending September 30, 1920, 10.85 feet 

April 22 (discharge, 3,660 second-feet); minimum stage, 5.58 feet November 10 

(discharge, 10.5 second-feet).

MILK RIVER AT MALTA, MONT.

LOCATION. In NW. \ sec. 17, T. 30 N., R. 30 E., at old highway bridge at Malta, in 

Phillips County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. July 31, 1902, to September 30, 1920.

GAGE. Chain fastened to guardrail on downstream side of bridge; read by employees 

of the United States Reclamation Serviced The gage .has "been moved several 

times to different points on bridge, but datum was not changed.

DISCHARGE MEASURBIIENTS.-* Made from bridge or by wading.

CHANNEL ANI> CONTROL. Bed of stream composed of gravel. Partial control at 

gage at low watefc but the principal control is formed by a bar or- ridge that produces a riffle half a mile below the gage. Shifts during high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 30, 1919, 4.70 feet April 6 (discharge, 1,760 second-feet); minimum stage 

0.9ft foot July 17 (discharge, 5.6 second^feet).

Maximum stage recorded during year ending September 30, 1920, 11.18 feet 

at 4.30 p. in. Mafch 24 (discharge, 5,460 second-feet); minimum stage, 0.94 foot 

November 4 (discharge, 4.0 second-feet).

1962-1920: Maximum stage recorded, 20.17 feet at 8 a. m. March 27, 1918 (discharge, 11,500 second-feet); no flow during periods in 1904, 1905, 1906, and 1910.

ICE. Stage-discharge relation seriously affected by ice. Station discontinued during 

winter.

DIVERSIONS. Entire run-off from drainage basin above does not pass the station for 

seven irrigation canals used to irrigate about 25,000 acres of land, divert water 

from Milk River and its tributaries between Havre and Malta. The United 

States Reclamation Service has constructed a diversion dam at Dodson, about 

17 miles above the station, which will'eventually divert water to irrigate about 

108,000 acres in Milk River valley. East of Malta two canals are nearing completion, one on each side, the combined capacity being 1.000 second-feet.

REGULATION. Part of flood flow is diverted into Nelson reservoir and held for use in 

irrigation.
MILK KIVEE BASIN.

ACCURACY. Stage-discharge relation changed during winter; affected, by ice during 

winter. Well defined rating curves used as follows: October 1 to December 22, 

1918; March 30 to November 5, 1919, and March 22 to September 30,1920. Gage 

read once daily to hundredths except for period March 15 to April 15,1920, when 

two readings daily were obtained. Daily discharge ascertained by applying 

gage height to rating table. Records good.

MILK RIVER NEAR VANDALIA, MONT,

LOCATION. In sec. 7, T. 30 N., E. 37 E., at Vandalia dam of United States Eeclamation Service, 2 miles west of Vandalia, Valley County.

DRAINAGE AREA. Not measured.

BECORDS AVAILABLE. May 5, 1915, to September 30, 1920. Station maintained 

at Hinsdale, 8 miles upstream, from May 13, 1908, to September 30, 1914. Discharge nearly same at both points.

<*AGE. Inclined gage on downstream side ot right abutment, read during period 

when crest gates are lowered and sluice gates open; chain gage on upstream side 

of right abutment, with datum at crest of dam used for periods when crest gates 

are open and sluice gates and canal gates are closed. Both gages read throughout 

year by employees of United States Reclamation Service.

DISCHARGE MEASUREMENTS. Made from cable 400 feet below dam or by wading.

CHANNEL AND CONTROL. Gravel bar at lower end of large pool below dam is control 

at medium and low stages; shifting. Left bank subject to overflow at high water.

EXTREME'S OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 27.50 feet at 8 a, m. April 4 (discharge, 15,700 second-feet); minimum 

stage, 3.3 feet June 5 (gates closed, movable crest down; no flow).

Maximum stage recorded duting~year ending Selptembe* 30, 1920/ chaingage, 

3.70 feet at 8 a. m. March 28 (discharge, 9,850 second-feet); minimum stage, 

inclined gage, 3.7 feet October 16-31 (discharge, 3 second-feet).

1908-1920: Maximum stage 34.5 feet April 11, 1917 (discharge, 25,200 secondfeet); no flow August 9-13, 1910, and June .5, 1919.

ICE. Stage-discharge relation for inclined gage affected by ice.

DIVERSIONS. Numerous irrigation canals divert water from the main stream and from 

nearly all of its tributaries.

REGULATION. Flow partly regulated by operation of gates in diversion dam and by 

storage in Nelson reservoir.

ACCURACY. Stage-discharge relation shifting. Standard rating curve used during 

1919 well defined below 800 second-feet; applied indirectly, except from February 

10 to April 30. During 1920 two poorly defined curves were used for lower gage, 

and one curve well defined between 200 and 4,500 second-feet used for gage above 

dam; shifting-control method used October 1-31 and November 12-16, 1919.

COOK CANAL NEAR CHINOOK, MONT.

LOCATION. In N. J sec. 30, T. 33 N., R. 20 E., at railway trestle just south of road 

running parallel to Great Northern Railway 3 miles east of Chinook, Blaine County.

RECORDS AVAILABLE. April 10,1905, to September 30, 1919.

GAGE. Enamel face nailed to upstream side of left abutment of wooden railway 

trestle where canal turns south and goes under railway; established April 20,1919. 

Prior to this date gage was a vertical staff on left bank about 1,000 feet above 

point at which canal turns west and runs parallel with the road. Gage read by 

Mrs. Coryl Martin.

DISCHARGE MEASUREMENTS. Made by wading where canal passes under the Great 

Northern Railway.

CHANNEL AND CONTROL. Channel of earth. No well defined control. Weeds grow 

along the bottom, causing backwater. Canal infested with beavers whose dams 

are likely to cause backwater.

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

denned below 40 second-feet. Gage read to hundredths once daily. Daily discharge obtained by applying daily gage height to rating table. Records good.

Cook canal diverts water from Battle Creek half a mile above gage, to irrigate lands 

in Milk River valley on south side of river. Canal crosses Milk River in a flume. 

Water can be wasted into Milk River at this flume, which is about 2 miles below the 

gage. Little water is returned to the stream intentionally, but the flume often acts 

as throttle when too much water is turned in at the headgate.

DISCHARGE MEASUREMENTS. Made from gaging bridge at gage.

CHANNEL AND CONTROL. Bed composed'of earth. No well defined control except

at check weir 1J miles downstream. 

ACCURACY. Stage-discharge relation not permanent. Three fairly well-defined rating

curves used during 1919; one fairly well defined curve used during 1920. Gage

read to hundredths once daily. Daily discharge determined by applying gage

heights to rating tables directly. Records fair.

Agency ditch takes water from south bank of Milk River in sec. 32, T. 32 N., R. 

23 E., for irrigation of lands on Fort Belknap Indian Reservation. Water not required 

for irrigation can be wasted into White Bear Creek, about 12 miles below headgate.

1906-1907; 1912-1920: Maximum stage recorded, 18.40 feet June 9, 1906, determined by leveling from high-water marks (approximate discharge determined 

from extension of rating curve, 6,220 second-feet); minimum discharge, no flow 

for periods in nearly every year.

ICE. Stage-discharge relation affected by ice; records discontinued during winterDIVERSIONS. Normal summer flow appropriated for use during irrigation season.

REGULATION. None.

ACCURACY. Stage-discharge relation slightly shifting. Rating curve used during 

1919 well defined; curve used during 1920 well defined between 13 and 1,000 

second-feet. Gage read to half-tenths once daily except during rapidly changing 

stage when it is read twice. Daily discharge ascertained by applying gage height 

to rating table. Records good.

450 feet above Chittenden bridge, replacing Friez water-stage recorder at same 

site which had been used since October 11,1916. Vertical staff at about same 

datum, 900 feet above present site used September 13,1913, to October 11,1916. 

Original gage used June 21 to September 12, 1913, was of same type and at 

same site but set to datum 1.03 feet higher than later staff. Readings on original 

gage reduced to datum of later staff. Gage read by Lynn Snow, park ranger in 

1919, and by E. T. Scoyen in 1920.

DISCHARGE MEASUREMENTS. Made by wading at low stages at a gravel and boulder 

section 100 feet below former staff gage. High-stage measurements made from 

cable about one-fifth of a mile above new gage.

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

boulders. Control formed by upper portion of the Upper Yellowstone falls; 

practically permanent for long periods; a change occurred during winter of 1919-20.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 1.87 feet June 27 (discharge, 1,900 second-feet); minimum stage, 0.72 

foot September 6 (discharge, 664 second-feet). A less discharge probably occurred 

during period of no record.

Maximum stage recorded during year ending September 30, 1920, from waterstage recorder, 3.43 feet at 5 p. m. July 7 (discharge, 5,480 second-feet); minimum 

stage 1.26 feet September 30 (discharge, 1,310 second-feet). A less discharge 

probably occurred during period of no record.

1913-1920: Maximum "stage recorded, 4.50 feet at 3 p. m. June 27, 1918 (discharge, 8,550 second-feet); minimum stage, September 6, 1919.

ICE. Stage-discharge relation affected by ice; gage reading, discontinued during 

winter.

DIVERSIONS. None above station.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during period of no record in 1919-20. 

Rating curve used for 1919 well defined between 650 and 8,550 second-feet; curveused for 1920 welLdefined above 1,200 second-feet. Staff gage read to hundredths 

twice daily June 27 to July 26,1919; thereafter water-stage recorder was operated. 

Daily discharge ascertained by applying to rating table mean daily gage heights. 

For periods when water-stage recorder was operated, mean daily gage heights 

were obtained by inspection of recorder graph. Records good except those-for 

September, 1919, which are fair.

DISCHARGE MEASUREMENTS. Made from bridge at Glendive or from ferryboat 100 

feet below dam.

CHANNEL AND CONTROL. Dam forming the principal control is a rock-filled timbercrib structure on fale fowidatwn, completed January 29, 1M&; 760 feet long, 

crosses the stream at right angles to current, and raises low-water level about i 

feet; specially designed to resist the destructive effects of ice by approach on a 

slope of 3 to 1;^ downstream" face ia-ogee-shaped and protected by-a-heavy rock 

. apron.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 4.3 feet May 29-30 (discharge, 26,400 second-feet); minimum stage, 0.7 

foot July 17 to August 1 and August 19-25 (discharge, 2,270 second-feet).

Maximum stage recorded during year ending September 30, 1920, 8.7 feet June 

19, 20 (discharge, 89,700 second-feet); minimum stage, 1.1 feet October 1-5 (discharge, 3,660 second-feet).

1903-1920: Maximum stage recorded for open channel, 10.8 feet June 20, 1918 

(discharge, 126,000 second-feet); minimum stage in 1919.
164 SURFACE WATER SUPPLY, 1919-1920, PART VI.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Lower Yellowstone canal, which diverts water to irrigate 66,000 acres 

of land, heads at north abutment of dam. Of several diversions from main stream 

above station United States Reclamation Service Huntley project and Billings 

Carey Act project are the largest. There are also numerous diversions on tributaries.

REGULATION. Yellowstone Lake and Shoshone reservoir on Shoshone River in Wyoming form only important regulation above and control only small part of flood flow.

ACCUHACY. Stage-discharge relation pennanent except for periods when ice accumulated on crest of dam. Rating curve is well defined. Gage read to tenths twice 

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

Records good except during periods affected by ice, for which they are fair.

The following discharge measurement was made by W. A. Lamb: 

September 16,1919: Gage height, 1.22 feet; discharge, 4,220 second-feet.

t>aily discharge, in second-feet, of Yellowstone River at Intake, Mont., for the years ending

Sept. 30, 1919 and 1920.

YEI^LOWSTONE EJVER BASIN. 171

JSWEETGAASS CREEK BELOW MELVILLE, MONT. . - :

XOCATION. Near middle of south line of sec. 27, T. 4 N., R. 15 E., at Crum ranch, 

one-fourth mile above head of diversion canal of Big Timber Carey project and 6 

miles southeast of Melville, Sweet Grass County.

DRAINAGE ABE A. 137 square miles (measured on topographic maps).

HECORDS AVAILABLE. April 1, 1909, to November 10, 1916, and August 8, 1917, to 

September 30, 1920; May 4, 1907, to April 1, 1909, at Adam's ranch 2£ miles 

downstream.

<jAGE.7-Oy^eirhanguag chain gage on left bank about 100 feet west of Crum's house; 

read by Rttjth b. Crum. : . ' ' " '

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

above gage.

 CHANNEL AND CONTROL. Stream bed of clean gravel; bar producing riffle about 300 

feet around a bend below gage likely to shift. Eight bank low; subject to overflow during high stages; left bank is a cut bank at the gage and not overflowed 

at that point; may be subject to overflow about 200feet below gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 30, 1919, 3.01 feet at 8 a. m. May 30 (discharge, 512 second-feet); minimum 

stage, 1.12 feet August 16,17, and 18 (discharge, 8 second-feet).

Maximum stage recorded during year ending September 30, 1920, 3.72 feet at 

8 a. m. June 12 (discharge, 1,020 second-feet); minimum stage, 1.40 feet at 10 

a. m. April 27 (discharge, 31 second-feet).

1909-1920: Maximum stage recorded, 4.2 feet June 27, 1916, determined from 

high-water marks (discharge determined from extension of rating curve, 1,700 

second-feet); minimum stage recorded, 1.12 feet August 16, 17, and 18, 1919 

(discharge, 8 second-feet).

ICE. Stage-discharge relation seriously affected by ice; data insufficient to warrant 

estimates of flow.

DIVERSIONS. There are adjudicated rights from Sweetgrass Creek amounting to over 

500 second-feet, and numerous ditches divert water both above and below the station. The diversion canal of the Big Timber Carey project has a capacity of 600 

second-feet and diverts into two connecting storage reservoirs, one of 6,000 and 

the other of 12,000 acre-feet capacity.

REGULATION. None.

AcctrRAGT.-^tag^tescharge relation fairly permanent, during 1919; not peraaaHent 

during 1920. Rating curve used October 1, 1918, to September 30, 1919, fairly 

well defined; shifting-control method used for 1920. Gage read to hundredths 

twice daily until September 4,1920, after which it was read once daily. Daily 

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

Rating curves used as follows: October 1, 1918, to March 15, 1919, well defined; 

March 16 to June 15 and June 20 to September 30,1919, fairly well defined curves. 

Standard rating curve for 1920 fairly well defined; applied indirectly during year. 

Operation of water-stage recorder satisfactory except as shown in footnote. Daily 

discharge ascertained by applying to rating tables daily mean gage height obtained by inspection of recorder graph. Records for 1919 good except for periods 

of missing gage heights, for which they are fair; records-for 1920 fair.

Banks high and not subject to overflow except at extreme stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30,1919, 5.15 feet June 3 (discharge, 5,420 second-feet); minimum stage recorded, 

2.28 feet July 15-18 (discharge, 516 second-feet).

Maximum stage recorded during year ending September 30, 1920, 9.52 feet at 

9 a. m. March 16 (stage-discharge relation affected by ice, discharge not computed); open channel flow, maximum stage in open water, 8.21 feet June 18 

(discharge, 25,500 second-feet); minimum stage 2.48 feet November 28 (disr 

charge, 619 second-feet).

1904-1920: Maximum stage recorded, 9,8 feet'June 17, 1908 (discharge, 40,800 

second-feet); minitnuni stage recorded in 1919.

ICE. Stage-discharge relation affected by ice; discharge computed from discharge 

measurement, daily gage heights, temperature records, and observer's notes.

DIVERSIONS. Water diverted few miles above station by private irrigation company 

to irrigate land on west side of river. Water is also diverted from Shoshone 

River at Corbett dam, Wyo., by United States Reclamation Service, and many 

private ditches divert water from tributaries above station.

REGULATION. Shoshone reservoir above Cody controls flow of Shoshone River, an 

important tributary of the Big Horn.

ACCURACY. Stage-discharge relation shifting at intervals. Two well-defined rating 

curves used during 1919; curve used from March 22 to September 30, 1920, well 

defined between 1,200 and 24,000 second-feet. Gage read to hundredths once a 

day, with occasional readings twice daily. Daily discharge ascertained by .applying gage height to rating table. Records good except during periods affected by 

ice for which they are fair.

LOCATION. In sec. 12, T. 47 N., R. 88 W., 800 feet east of county bridge at Burke

ranch, 5 miles above Tensleep, Washakie County. Nearest tributary, Canyon

Creek, enters a quarter of a mile upstream. 

DRAINAGE AREA. 228 square miles (measured on base map of Wyoming; scale,

1:500,000). 

RECORDS AVAILABLE. September 21, 1910, to December 31, 1912; April 19, 1915, to

September 30, 1920.

GAGE. Stevens water-stage recorder installed May 11, 1918, at left bank 800 feet upstream from county bridge opposite vertical rock cliff, and referred to inclined

gage used previously; inspected by Miss Myrtle McCreery and Mrs. Zina McCreery.

Datum lowered 1.00 foot September 26, 1916.

DISCHARGE MEASUREMENTS. Made from cable 100 feet below gage or by wading. 

CHANNEL AND CONTROL. Channel composed of coarse gravel and small boulders.

Control located just below gage at rapids, which shifted slightly in 1920. Right

bank is vertical rock cliff; left bank subject to overflow at extreme high water. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September

30, 1919, 4.6 feet at 4 a. m. May 30 (discharge, 1,250 second-feet); minimum stage,

0.93 foot at 4 p. m. July 28 (discharge, 36 second-feet). 

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

recorder, 6.0 feet at 6 a. m. June 9 (discharge, 2,050 second-feet); minimum stage,

0.90 foot at 10 a. m. March 6 (discharge, 34 second-feet).

1910-1912; 1915-1920: Maximum stage recorded, 6.8 feet at 4 a. m. June 11,1918

(discharge, 2,360 second-feet); minimum stage in 1920. 

ICE. Stage-discharge relation not affected by ice. 

DIVERSIONS. Diversion of about 8 second-feet for power above station. Prior to

July 1, 1919, adjudicated diversions of 1.2 second-feet for irrigation above station

and 36 second-feet below. 

REGULATION. Diurnal fluctuation during spring, caused by alternate melting and

freezing of mountain snow.
196 SURFACE WATER SUPPLY, 1919-1920, PART VI.

ACCURACY. Stage-discharge relation shifted slightly during 1920. Two rating curves 

well defined, one used from October 1,^1918, to March 31, 1920, and the other from 

April 1 to September 30, 1920. Operation of water-stage recorder satisfactory, 

except as shown in footnote to daily-discharge table. Staff gage read to hundredths once daily October 1, 1918, to May 8, 1919, and July 8 to September 20, 

1919. Daily discharge ascertained by applying to rating table mean daily gage 

heights obtained by inspection of recorder graph and by applying the one daily 

gage height actually observed. Records excellent except for periods when recorder 

failed to operate, for which they are good.

198 SUKFACE WATEB SUPPLY, 191&-1920, PAET VI.

PMNTROCK CREEK NEAR BONANZA, WTO.

LOCATION. About sec. 19, T. 49 N., R. 90 W., at Paumer ranch, 1| miles above 

Bonanza, Big Horn County. No tributary between station and mouth, half a 

mile below.

DRAINAGE AREA. 398 square miles (measured on base map of Wyoming; scale, 

1:500,000).

RECORDS^ AVAILABLE July 28, 1910, to October 31, 1912; April 19, 1915, to September 30, 1920. - '

GAGE. Chain on right bank 300 feet below ranch; installed April 11, 1917, to replace 

staff gage at the same place and datum used since April 19,1915. Read by Mrs. 

William Paumer. From July 28, 1910, to October 31, 1912, chain located near 

house. No definite relation between gages at two locations, as high water changed 

channel between.

DISCHARGE MEASUREMENTS. Made from cable 65 feet below gage or by wading.

CHANNEL AND CONTROL. Bed composed of gravel. Control at rapids composed of 

small boulders 150 feet below gage; shifting. Right bank subject to overflow at 

stage of 2 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 3.4 feet at 8 a. m. May 20 (discharge, 1,060 second-feet); minimum stage, 

0.67 foot on July 27 (discharge, 0.7 second-foot).

Maximum stage recorded during year ending September 30, 1920, 4.6 feet at 

8 a. m. June 10 (discharge, 2,340 second-feet); minimum discharge probably 

occured during winter.

1910-1913; 1915-1920: Maximum stage recorded, 5.3 feet at 8 a. m. June 12, 

1918 (discharge, 3,390 second-feet); minimum stage in 1919.

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

during winter.

DIVERSIONS. Prior to July 1, 1919, adjudicated diversions of 68 second-feet from 

Paintrock Creek, all above station.

REGULATION. Diurnal fluctuation during spring, caused by alternate melting and 

freezing of mountain snow.

ACCURACY. Stage-discharge relation not permanent. Rating curve well defined 

below 600 second-feet; shifting-control method used October 1-12,1918, and June 

1 to September 30, 1920. Gage read to hundredths twice daily. Daily discharge 

ascertained by applying daily mean gage height to rating table. Records excellent except for periods of shifting control and when discharge is above 600 secondfeet, for which they are fair.

Greybull River above station and 221 second-feet below station.

REGULATION. None.

ACCURACY. Stage-discharge relation apparently permanent. Rating curves not 

well defined. Operation of water-stage recorder satisfactory. Daily discharge 

ascertained by applying to rating table daily mean gage height obtained by inspection of recorder graph. From July 18 to August 28 staff gage read to quartertenths twice daily. Records good.

RIVER HEAR ISHAWOOA, WYO.

LOCATION. In SW. i sec. 23, T. 51 N., R. 104 W., at Hartung's private bridge, If 

miles north of Ishawooa, Park County. Nearest tributary, Bull'Creek; enters 

1J miles downstream.

DRAINAGE AREA. 532 square miles (measured on base map of Wyoming; scale, 

1:500,000).

RECORDS AVAILABLE. May 7, 1915, to September 30, 1920.

GAGE. Vertical staff fastened to bridge piling; read by Albert Hartung. Prior to 

May 24,1918, gage half a mile upstream at Spaulding's ranch. Flow at two points 

comparable.

DISCHARGE MEASUREMENTS. Made from suspension bridge and by wading.

CHANNEL AND CONTROL. Bed of stream composed of coarse gravel; shifting during 

high water. No well-defined control. Banks not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 30, 1919, 4.1 feet at 6.30 a. m. May 28 (discharge, 2,870 second-feet); minimum discharge probably occurred during winter.

Maximum stage recorded during year ending September 30, 1920, 4.8 feet at 

6 a. m. June 17 (discharge, 3,690 second-feet); minimum discharge probably occurred during winter.

, 1915-1920: Maximum stage recorded, 7.0 feet at 6.45 a. m. June 14, 1918 (discharge, 7,740 second-feet); minimum discharge probably occurred during winter.

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

DIVERSIONS. Prior to July 1, 1919, adjudicated diversions of 31 second-feet from 

Shoshone River above station and 162 second-feet between it and Shoshone 

reservoir.

REGULATION. Diurnal fluctuation during spring, caused by alternate melting and 

freezing of mountain snow.

ACCURACY. Stage-discharge relation not permanent. Rating curve used from 

October 1,1918, to June 7,1920, fairly well defined; applied indirectly May 15 to 

September 30, 1919. Curve used June 8 to September 30, 1920, well defined; 

applied indirectly June 8-12, Gage read to bundredtbs twice daily. Daily 

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

SHOSHONE RIVER AT CORBETT DAM, WYO.

LOCATION. In NE. i sec. 7, T. 53 N., R. 100 W., at Corbett diversion dam, 8 miles 

below Cody, in Big Horn County.

DRAINAGE AEEA. Not measured at this station; drainage area above Cody is 1,400 

square miles. Sage Creek, the only important tributary that enters between 

this station and Cody, drains about 25 square miles.

RECORDS AVAILABLE. April 20, 1908, to September 30, 1920.

GAGE. Staff gage 40 feet upstream from the crest of the dam; readings represent height 

of water above crest. It is read once a day during the irrigation season and at 

irregular intervals during the winter by employees of the United States Reclamation Service.

DETERMINATION OP DISCHARGE. Discharge computed by considering the dam as a 

weir and the sluice gates as submerged orifices. The following formula for 

discharge over the crest was developed from measurements at Cody, Wyo.: 

Q=3.50 BH1 - 58.

CHANNEL AND CONTROL. The crest of the dam forms a permanent control. The 

dam is of reinforced concrete of the buttressed type, having on the upstream side 

a deck 2£ feet thick, sloping 1 to 1, and supported by buttresses 2 feet thick spaced 

14 feet on centers; it raises the low-water elevation of the river 10.2 feet; length 

between abutments, 400 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30,1919,1.18 feet June 9 (discharge, 1,820 second-feet; discharge through Corbett 

tunnel, 404 second-feet; total, 2,220 second-feet); minimum stage, 0.52 foot March 

1-10 (discharge, 498 second-feet; no flow through tunnel).

Maximum stage recorded during year ending September 30, 1920, 2.90 feet 

July 5 (discharge, 7,530 second-feet; discharge through Corbett tunnel 506 secondfeet; total, 8,036 second-feet); minimum stage recorded 0.53 foot January 1-29 

(discharge, 515 second-feet; no flow through Corbett tunnel).

1908-1920: Maximum stage recorded, 5.00 feet June 15, 1918 (total discharge, 

18,700 second-feet); no flow October 21 to November 19, 1909.

ICE. Stage-discharge relation not seriously affected by ice; open channel rating 

curve assumed applicable.

DIVERSIONS. Little water is diverted above this station.

REGULATION. Shoshone reservoir, having a capacity of 456,000 acre-feet, partly 

regulates the flow.
YEUX>WSTONE BIVER BASIN. 207

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

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

by applying gage height to rating table and adding the daily flow through tunnels. 

Records good.

The following discharge measurement was made by W. A. Lamb: 

August 24, 1918: Gage height, 0.97 foot; discharge, 1,580 second-feet.

Daily discharge, in second-feet, ofShoshone River, including tunnels, at Corbett dam, Wyo.t 

for the years ending Sept. SO, 1917-1920.

ROTTENGRASS CREEK NEAR ST. XAVIER, MONT.

LOCATION. In NW. \ sec. 6, T. 5 S., R. 23 E., one-fourth mile above crossing of Big 

Horn canal, on Crow Indian Reservation, 4 miles south of St. Xavier, in Big Horn 

County.

DRAINAGE ABBA. Not measured.

RECORDS AVAILABLE. September 9,1911, to September 30,1919.
YEULOWSTONE RIVER BASIN. 215

GAGE. Overhanging chain on left bank about one-fourth mile above crossing of Big

Horn canal; read by W. H. Ferguson April 1 to September 30 usually two or

three times a week. 

DISCHARGE MEASUREMENTS. Made from footbridge about 500 feet above gage or by

wading. 

CHANNEL AND CONTROL. Bed of stream gravel and silt; shifts. Banks above and

below gage high and steep; not subject to overflow below gage height 11 feet

(discharge about 400 second-feet). 

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

4.1 feet at 8 a. m. April 25 (discharge, 25 second-feet); stream reported dry August

22 to September 30. 

1911-1919: Maximum stage recorded, 11.3 feet March 30, 1917 (approximate

discharge 500 second-feet); minimum stage recorded, stream dry August 22 to

September 30,1919. 

ICE. No records during winter. 

DIVERSIONS. None. Waste water from Big Horn canal enters the creek just above

gage. This amount was estimated at 2.5 second-feet May 25. 

REGULATION. None. ;; 

ACCURACY. Stage-discharge relation permanent for period covered by gage readings.

Rating curve is fairly well defined between 4 and 12 second-feet. Gage read to

nearest tenth two or three times a week. Daily discharge ascertained for days of

gage readings by applying gage heights to rating table. For intervening days the

discharge has been interpolated; no flow after August 21. Records are poor,

owing to the insufficient number of gage readings.

LODGE GRASS CREEK AT LODGEGRASS, MONT.

LOCATION. In S. £ sec. 13, T. 6 S., R. 35 E., 600 feet above Chicago, Burlington & 

Quincy Railroad bridge and a quarter of a mile south of Lodgegrass, on Crow 

Indian Reservation, Big Horn County.

DRAINAGE AREA. Not measured.
YELLOWSTONE RIVER BASIN. 221

RECORDS AVAILABLE. March 24, 1916, to September 30, 1920, at present site; September 9, 1911, to December 28, 1915, at old site 6 miles above in SW. J sec. 29, 

T. 6 S., R. 35 E., one-quarter mile above Lodgegrass ditch.

GAGE. Wire on left bank; read by Edward Commock and C. A. Gardner.

DISCHARGE MEASUREMENTS. Made from railway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of gravel and boulders; shifting control at 

Sandstone lodge, overlain by boulders and gravel; affected by backwater from 

Little Horn River and by growth of moss.

EXTREMES, OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 2.20 feet May 25-26 (discharge^ GO second-feet); minimum discharge, 

no flow July 12 to September 30.

Maximum stage recorded during year ending September 30, 1920, 4.00 feet at 

5 p. m. March 23 (discharge, 525 second-feet); minimum stage 1.28 feet September 

1 (discharge, 0.9 second-feet).

1911-1920: Maximum stage, 7.0 feet June 13, 1915 (discharge, 695 second-feet); 

minimum discharge occurred in 1919.

ICE. Stage-discharge relation affected by ice; discharge not computed during winter.

.DIVERSIONS . Lodgegrass ditch diverts water for irrigation about 6 miles above present 

site. Old station was about one-fourth mile above headworks of this ditch; 

hence flow during irrigation season is not comparable to that at present site.

REGULATION . None.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve fairly 

well defined during 1919, but poorly defined during 1920; applied indirectly 

because of shifting control. Gage read once daily to tenths during 1919 and to 

quarter-tenths during 1920. Records poor for 1919 and fair for 1920.

miles downstream.

DRAINAGE AREA. 204 square miles (measured on topographic map).

RECORDS AVAILABLE. November 18,1918, to September 30, 1920.

GAGE. Stevens water-stage recorder at left bank 1,000 feet below headgate'of Highline 

canal; inspected by Hugh Watson. »

DISCHARGE MEASUREMENTS. Made from cable 100 feet downstream or by wading,

CHANNEL AND CONTROL. Bed composed of boulders and coarse gravel, well compacted; should be permanent. Control 200 feet downstream; shifts slightly 

during high water.

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

from water-stage recorder, 3.4 feet at 3 a. m. May 20 (discharge, 690 second-feet); 

minimum stage, 1.30 feet at 10 a. m. August 27 (discharge, 33 second-feet). 

Maximum stage during year ending September 30, 1920, 4.35 feet at midnight 

June 10 (discharge, 1,700 second-feet); minimum stage, 1.00 foot at 9 p. m. 

November 29 (discharge, 15 second-feet).

ICE. Stage-discharge relation slightly affected by ice for shorf periods.

DIVERSIONS. Only diversion above station is Highline canal. During 1920, 3,940 

acre-feet diverted between May 27 and September 30. Prior to July 1, 1919, 

adjudicated diversions of 166 second-feet below station.

ACCURACY. Stage-discharge relation shifted during high water in 1920; slightly 

affected by ice during winter. Rating curve used from November 18, 1918, to 

June 16, 1920, well defined below 1,100 second-feet. Curve used from June 27 

to September 30, 1920, fairly well defined; shifting-control method used June 

17-24. Operation of water-stage recorder satisfactory except for short periods as 

shown in footnote to daily-discharge table. Daily discharge ascertained by 

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

recorder graph. Records excellent except during June, 1920, for which they are 

good.

CLEAR CREEK NEAR BUFFALO, WYO.

LOCATION. In sec. 6, T. 50 N., R. 82 W., just above power house of Buffalo Manufacturing Co., 4 miles west of Buffalo, Johnson County.

DRAINAGE AREA. 120 square miles (measured on topographic map).

RECORDS AVAILABLE. June 16, 1917, to September 30, 1920. From May 2, 1896, 

to February 28, 1900, station maintained at measuring flume 1 mile upstream. 

Flow at two points comparable. From October 24, 1902, to December 31, 1904, 

and May 8, 1911, to June 11, 1912, station maintained at highway bridge in Buffalo. Flow not comparable as several ditches divert water between.

GAGE. Chain at left bank, 300 feet above power house; read by Miss Ruby Bell.

DISCHARGE MEASUREMENTS. Made from cable 50 feet upstream from gage or "by 

wading.

CHANNEL AND CONTROL. Bed composed of large boulders. Control at large boulders 

10 feet downstream which shift slightly at infrequent intervals. Banks not 

subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 30, 1919, 2.8 feet at 9 a. m. May 21 (discharge, 433 second-feet); minimum 

discharge occurred during winter.

Maximum stage recorded during year ending September 30, 1920, 3.9 feet at 

6 a. m. June 11 (discharge, 910 second-feet); minimum discharge occurred during 

winter.

1917-1920: Maximum stage recorded, 4.2 feet at 6.30 a. m. June 18, 1917 (discharge, 1,120 second-feet); minimum discharge occurred during winter.
YEULOWSTONE RIVER BASIN. 231

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

during winter.

DIVERSIONS. Pipe-line of Buffalo Mfg. Co. diverts water from Clear Creek, 1£ miles 

upstream. A separate record of flow through pipe line is kept and flow added to 

that at gaging station to give total flow of creek. Four Lakes and French Creek 

qanal, and North Fork and French Creek canal divert water fromi Clear Creek above 

the station. During 1919, 4,400 acre-feet were diverted between May 30 and 

September 30. During 1920, 2,700 acre-feet were diverted between June 5 and 

July 31.

- Prior to July 1, 1919, adjudicated decrees for diversions of 372 second-feet 

below station.

REGULATION. Alternate melting and freezing of mountain snow during spring of 

year causes diurnal fluctuations in flow. No artificial regulation.

ACCURACY. Stage-discharge relation not permanent. Rating curve used from 

October 1, 1918, to October 21, 1919, well defined; shifting-control method used 

June 1 to July 10. Curve used from March 14 to September 30,1920, well defined. 

Gage read to hundredths twice daily. Daily discharge ascertained by applying 

daily mean gage height to rating table. Records good.

LOCATION. In NW. J sec. 18, T. 53 N., R. 80 W., at highway bridge a quarter of a 

mile from Ucross, Sheridan County. No tributary between station and mouth, 

half a mile below.

DRAINAGE AREA. 253 square miles (measured on base map of Wyoming; scale, 

1:500,000).

RECORDS AVAILABLE. May 12, 1917, to September 30, 1920.

GAGE. Chain attached to highway bridge; read by Miss Alma Larson.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of silt and gravel which will shift. Control 50 feet downstream at riffle composed of compact gravel; shifting at long 

intervals. Banks not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 30, 1919, 3.2 feet at 8 a. m. May 21 (discharge, 460 second-feet); minimum 

stage recorded, 1.04 feet on July 8 (discharge, 1.2 second-feet).

Maximum stage recorded during year ending September 30, 1920, 4.3 feet at 

6 a. m. June 10 (discharge, 1,140 second-feet); minimum stage recorded, 1.00 

foot at 8 p. m. July 30 (discharge, 1.0 second-foot).

1917-1920: Maximum stage recorded, 5.0 feet from high-water mark on morning of June 11, 1918 (discharge, 1,900 second-feet); minimum stage recorded in 

1920.

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

DIVERSIONS. Prior to July 1, 1919, adjudicated diversions of 61 second-feet from 

Piney Creek between Kearney and Ucross.

REGULATION. Headwaters are chain of small mountain lakes, the largest of which, 

Cloud Peak, is used as reservoir for irrigation. Alternate melting and freezing 

of mountain snow in spring of year causes some diurnal fluctuation.

ACCURACY. 1919: Stage-discharge relation permanent during year. Rating curve 

well defined. Gage read to half-tenths once or twice daily. Daily discharge 

ascertained by applying one daily gage height or the mean of two daily gage 

heights to the rating table. Records good except for days of missing gage heights, 

for which they are fair. 

Owing to unsatisfactory gage reading daily discharge for 1920 is not published.

LITTLE MISSOURI RIVER NEAR ALZADA, MONT.

LOCATION. Near southwest corner of T. 8 S., R. 60 E., at Walker ranch, 300 yards 

below site of proposed dam, 2 miles below mouth of Thompson Creek, and 4 miles 

below Alzada, Carter County.

DRAINAGE AREA. 780 square miles.

RECORDS AVAILABLE. June 18, 1911, to September 30, 1920.

GAGE. Chain on right bank; read by John Walker. Gage used during 1911, vertical 

staff on left bank, 150 feet downstream. Datum of chain gage 0.08 foot lower than 

that of staff gage.

DISCHARGE MEASUREMENETS. Made by wading or from cable.

CHANNEL AND CONTROL. Bed composed -of gravel. Control at gravel riffle a short 

distance downstream; slightly shifting.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30,1919, 7.70 feet at 7 a. m. July 30 (discharge, 1,360 second-feet); no flow June 12 

to July 4, July 14-29, and August 20 to September 30.

Maximum atage recorded during year ending September 30, 1920, 14.2 feet on 

March 22; stage-discharge relation affected by ice jams below the gage (discharge 

not computed); maximum stage, open channel, 9.1 feet May 12 (discharge, 1,740 

second-feet); no flow October 1-14.

1911-1920: Maximum stage recorded, 15.3 feet April 6, 1912 (discharge, 4,550 

second-feet); channel dry for several periods.

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. None.

REGULATION. None of importance. Some flood water in spring is stored in coulees 

on tributaries for use in irrigating small tracts.

ACCURACY. Stage-discharge relation slightly shifting. Rating curve used from 

October 1, 1918, to June 19, 1920, well defined aboye 80 second-feet, poorly defined below; curve used from June 20 to September 30,1920, fairly well defined; 

shifting-control method used July 9-14, August 11-20, 1919. Gage read to hundredths twice daily, and oftener during high stage. Daily discharge ascertained 

by applying daily mean gage height to rating table. Records for 1919 fair for 

high water and poor for low water; records for 1920 good.

The following discharge measurement was made by G. H. Ellison: 

July 9, 1920 Gage height, 2.29 feet; discharge, 22.8 second-feet.

HEABT RIVER BASIN.

HEART BIVER NEAR RICHARDTON, N. DAK.

LOCATION. In sec. 21, T. 138 N., R. 92 W., opposite residence of W. F. Church, 1 

mile below highway bridge and 11 miles south of Richardton, in Stark County.

DRAINAGE AREA. 1,250 square miles.

RECORDS AVAILABLE. May 18, 1903, to September 30, 1920.

GAGE. Chain on cantilever timber opposite observer's house on right bank of river. 

Auxiliary chain gage on highway bridge, used March 23 to April 1, 1920, because 

of damage to regular gage. The two gage datums are so related that readings at 

the bridge are approximately 20.0 feet less than on the gage regularly used. 

Read by W. F. Church.

DISCHARGE MEASUREMENTS. At. high stages from bridge; at ordinary low stages 

by wading.

102724 23 WSP 506 16
242 SURFACE WATER SUPPLY, 1919-1920, PART VI.

CHANNEL AND CONTROL. Channel fairly permanent, but control sometimes changed 

considerably for short periods in former years by the building of dams by beavers 

one-fourth mile below the^age.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 29.6 feet April 1 (discharge, 966 second-feet); no flow during several 

days in July, August, and September.

Maximum discharge recorded during year ending September 30, 1920, 1,500 

second-feet March 29; minimum stage 24.0 feet October 5 (discharge, 0.1 secondfoot).

1903-1920: Maximum stage recorded, 25.9 feet from gage at highway bridge 

June 10, 1906 (discharge, 8,020 second-feet); river reported standing in pools 

during periods in 1903, 1905, 1914, and 1919.

ICE. Stage-discharge relation seriously affected by ice; flow not determined during 

winter.

REGULATION AND DIVERSIONS. No storage or diversions appreciably affecting the 

discharge.

ACCURACY. Stage-discharge relation not permanent. Eating curve fairly well 

defined below 2,870 second-feet. Gage read once daily to half-tenths. Daily 

discharge ascertained by applying gage height to rating table. Records poor.

CHEYENNE RIVER BASIN.

CHEYENNE RIVER NEAR HOT SPRINGS. S. DAK.

LOCATION. In sec. 9, T. 9 S., R. 5 E., 1 mile above dam site of proposed Angostura 

irrigation project, 5 miles south of Cascade Springs, and 11 miles south of Hot 

Springs, Fall River County. Nearest tributary, Cascade Creek, enters 2£ miles 

above.

DaAJNAc*: AREA. 8,720 square miles (measured chiefly on base map of Wyoming; 

scale, 1 :500,000).

RECORDS AVAILABLE. September 11, 1914, to September 30, 1920, when station was 

discontinued. Station maintained at Edgemont June 19, 1903, to November 30, 

1906, but flow is not directly comparable, as number of small tributaries intervene.

GAGE. Inclined staff on right bank one-third of a mile below Noerenberg's fruit 

farm; read by Fred Noerenberg and H. L. Parrish. *

DISCHARGE MEASUREMENTS. Made from cable 75 feet below gage or by wading.

CHANNEL AND CONTROL. Bed composed of compacted gravel on which silt is deposited; shifts frequently. Principal control a short distance downstream; will 

shift during severe floods. Right bank subject to overflow for distance of 100 

feet at stage of 14 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30,1919, 8.8 feet at 10 a. m. July 5 (discharge, 10,300 second-feet); minimum discharge of 16 second-feet occurred January 3.

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

29.2 feet about 4 a. m. May 12 (discharge, estimated at 150,000 a second-feet); 

minimum discharge of 26 second-feet occurred November 18.

1914-1920: Maximum stage in 1920; minimum stage, 0.40 foot on September 6, 

1918 (discharge, 10 second-feet).

ICE. Spring water from Cascade Creek prevents formation of ice except for brief 

periods.

DIVERSIONS. Permits granted for diversions amounting to 93.4 second-feet from 

Cheyenne River above station and 43.4 second-feet from Cascade Creek.

REGULATION. None.

ACCURACY. Stage-discharge relation shifted at intervals. 'Standard rating curve 

used during 1919 well defined; applied indirectly for shifting control October 6 

to December 5, 1918. Curve used October 1, 1919, to May 11, 1920, well defined 

between 24 second-feet and 24,000 second-feet; curve used from May 14 to September 30 poorly defined. Gage read twice daily, to hundredths during 1919 

and to half-tenths during 1920. Records for 1919 good; for 1920 fair before high 

water, poor afterwards.

BELLE FOTTRCHE RIVER NEAR BELLE FOTJRCHE, S. DAK.

LOCATION. In sec. 2, T. 8 N., R. 2 E., at diversion dam of Belle Fourche irrigation 

project, 1J miles below Belle Fourche, in Butte County.

DRAINAGE AREA. 4,270 square miles.

RECORDS AVAILABLE. May 10 to November 30, 1906; January 1, 1912, to September 30, 1920. May 26, 1903, to June 23, 1906, for station at the west outskirts of 

Belle Fourche; the records at these points are not directly comparable, as Redwater River enters between the two stations and water is diverted from Belle 

Fourche River.

GAGES. Inclined staff 100 feet from crest of diversion dam, and a gage in canal. See 

" Computation of discharge."

COMPUTATION OF DISCHARGE. The following information was supplied by the United 

States Reclamation Service: The records of daily discharge represent the entire 

flow of the river at the diversion dam and have been corrected for water diverted 

through Inlet canal and passed through the sluice gates. The diversion dam acts 

as a weir; the crest is 400 feet long; the gage is about 100 feet from the crest and is 

read twice daily. Careful discharge measurements were made in the river above 

and below the dam before the coefficient was established, and the discharge rating 

table as originally computed has not been changed. The quantity diverted is 

determined at a gaging station maintained on Inlet canal, and the rating curve 

is checked by frequent discharge measurements. The sluice gates are seldom 

used and the flow through them is estimated.

DIVERSIONS. In that part of the drainage area in Wyoming prior to July 1, 1919, 

adjudicated diversions of 14 second-feet from Belle Fourche River and 258 

second-feet from tributaries. Below the station, authorized diversions of 3,102 

second-feet from Belle Fourche River.

ACCURACY. The U. S. Reclamation Service considers the records fair.

COOPERATION. Complete records furnished and stations maintained by U. S. Reclamation Service.

LITTLE SIOUX RIVER BASIN. 

LITTLE SIOUX RIVER AT CORRECTIONVILLE, IOWA.

LOCATION. In sec. 1, T. 88 N., R. 43 W. at Illinois Central Railroad bridge half a 

mile southwest of Correctionville, Woodbury County, and 54 miles above mouth.

DRAINAGE AREA. 2,190 square miles (measured by engineers of the Iowa Highway 

Commission from United States post-route map; scale, 1 inch=l mile).

RECORDS AVAILABLE. May 28, 1918, to September 30, 1920.

GAGE. Chain gage attached to upstream guardrail of center span of Illinois Ce'ntral 

Railroad bridge. Read to hundredths once daily by Edwin H. Worrell.

DISCHARGE MEASUREMENTS. At ordinary stage, made from downstream side of 

highway bridge one-fourth mile above gage. Flood measurements from downstream side of bridge to which gage is attached.

CHANNEL AND CONTROL. Stream bed, sand and clay; no well-defined control, both 

banks subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30,1919,19.57 feet at 9.15 p. m. June 12 (discharge, 20,700 second-feet); minimum 

stage, 2.16 feet at 4.15 p. m. October 25 (discharge, 69 second-feet).

Maximum stage recorded during year ending September 30, 1920, 17.32 feet 

at 8.50 a. m. March 13 (discharge estimated as 8,920 second-feet); minimum discharge somewhat less than 130 second-feet in February.

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. There is a small power development at Correctionville, but it is not 

thought that this has any appreciable effect on the stage.
LITTLE SIOUX RIVER BASIN. 249

ACCURACY. Stage-discharge relation changed during spring break-up in 1920; not 

permanent. Rating curve used before and after the change well defined between 

100 and 3,000 second-feet. Beyond this limit the rating is roughly approximate, 

owing to lack of discharge measurements. On account of the flat valley and 

meandering character of the river, the stage-discharge relation varies with the 

duration of a flood. Two high-water ratings have been used; one for flashy 

floods and the other for those of long duration. Gage read to hundredths once 

daily and oftener during periods of rapidly changing stage. Daily discharge 

ascertained by applying daily gage height to rating table except for period when 

stage-discharge relation was affected by ice when it was obtained by correcting 

daily gage heights for ice effects by means of a discharge measurement, observer's 

notes, weather records, and comparison with open-water station.

Open-water records good except for periods of high water, for which they are 

only fair. Winter records roughly approximate.

BOYER RIVER BASIN. 

BOYER BJVER AT LOGAN, IOWA.

LOCATION. In sec. 24, T. 79 N.f R. 43 W. at highway bridge south of Logan, Harrison 

County, 30 miles above mouth.

DRAINAGE AREA. 845 square miles (measured by engineers of the Iowa Highway 

Commission from United States post route map; scale, 1 inch = 1 mile).

RECORDS AVAILABLE. May 24,1918, to September 30,1920.

GAGE. Chain gage attached to upstream handrail of bridge; read by C. F. Peckenpough.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Channel is a dredged ditch with clay bottom and sides. 

Banks subjects to overflow during extreme floods. Control consists of the remains 

of an old grist-mill dam on a limestone ledge about 500 feet below the gage.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30,1919,17.83 feet at 11.30 a. m. April 23 (discharge, 6,790 second-feet); minimum 

stage 1.83 feet October 7 (discharge, 3 second-feet).

Maximum stage recorded during year ending September 30, 1920, 10.1 feet at 

6 p. m. August 20 (discharge, 2,610 second-feet); minimum stage, 1.96 feet at 

9 a. m. September 22 (estimated discharge, 44 second-feet).

1918-1920: Maximum stage recorded 17.9 feet at 11 a. m. June 5, 1918 (discharge estimated, 6,960 second-feet); no flow September 27-29,1918.
252 SURFACE WATER SUPPLY, 1919-1920,, PART VI.

ICE. During extreme cold weather the stage-discharge relation is affected by ice. 

The water at the control is very swift and seldom freezes.

ACCURACY. Stage-discharge relation affected by backwater when Missouri River is 

in flood stage. The rating was changed considerably in March, 1920, by the 

heavy ice carrying out some of the timbers in the remains of the old dam forming 

the control. Rating curve used prior to this change well defined between 30 and 

3,000 sacond-feet; curve used after the change, well denned between 100 and 

3,000 second-feet; extsnsions of both curves roughly approximate, owing to lack of 

discharge measurements. Gage read to hundredths once daily except for days 

of rapidly changing stage. Daily discharge ascertained by applying daily gage 

height to rating table except for period in which stage-discharge relation was 

affected by ice, for which it was obtained by correcting dajily gage height for ice 

effect on basis of one discharge measurement, observer's notes, weather records, 

and comparison with flow at open-water stations. Open-water records good; 

records for periods of ice effect roughly approximate.

1919 and 1920.

NORTH PLATTE RIVER AT PATHFINDER, WYO.

LOCATION. In sec. 24, T. 29 N., R. 84 W., a quarter of a mile below Pathfinder dam 

and one-third of a mile below old post office of Pathfinder, Natrona County. 

Nearest tributary, Canyon Creek, enters 2 onles above, in the reservoir.

DRAINAGE AREA. 10,700 square miles (measured on base map of Wyoming; scale, 

1:500,000).

RECORDS AVAILABLE. May 9, 1905, to September 30, 1920.

GAGE. Chain gage on left bank a quarter of a mile below Pathfinder dam; read by 

employee of United States Reclamation Service.

DISCHARGE MEASUREMENTS. Made from cable, 50 feet above gage.

EXTREMES OP DISCHARGE. No data.

WINTER FLOW. Practically cut off by storage in reservoir.

DIVERSIONS. Prior to July 1, 1919, adjudicated diversions of 383 second-feet from 

tributaries entering the North Platte between station above Pathfinder and this 

station. Near Whalen, 150 miles below, water from Pathfinder reservoir is diverted by Interstate canal and used to irrigate land in Wyoming and Nebraska.

REGULATION. Pathfinder dam forms reservoir of 1,070,000 acre-feet capacity, which 

materially changes natural run-off of river.

COOPERATION. Complete records furnished by United States Reclamation Service.

PLATTE EIVEE BASIN. 265

NORTH PLATTE RIVER ABOVE AND BELOW WHALEN, WYO.

LOCATION. In sec. 11, T. 26 N., R 65 W., at diversion dam at Whalen, Goshen County. 

Nearest important tributary is Cottonwood Canyon Creek, an intermittent stream 

which enters 1| miles below.

DRAINAGE AREA. 16,300 square miles (measured on base map of Wyoming; scale, 

1:500,000.)

RECORDS AVAILABLE. May 1, 1909, to September 30, 1920. Records above Whalen 

represent discharge above the diversion dam and those below Whalen, quantity 

passing over dam (overfall weir). Difference between two records represents 

amount diverted by Interstate and Fort Laramie canals.

GAGE. To determine flow over weir vertical staff is used, its zero being weir crest. 

The discharge is then computed by a weir formula. There are also four sluice 

gates in dam, through which discharge is computed. In river, 75 feet downstream 

from weir gage, is another with zero 10 feet lower. Second gage only used in computing discharge through gates when openings are submerged. Discharge through 

headgates of Interstate and Fort Laramie canals is computed from gate openings. 

Vertical staffs in canals below headgates are used in computing discharge when 

headgate openings are submerged.

DISCHARGE MEASUREMENTS. Made from cable 1 mile below weir, in order to check 

the coefficients used in discharge computations.

DIVERSIONS. Prior to July 1, 1919, adjudicated diversions from North Platte River 

of 429 second-feet between Pathfinder and the Whalen gaging station, exclusive 

of the diversion by the United States Reclamation Service. Between Whalen and 

the State line there are adjudicated diversions of 236 second-feet.

REGULATION. Discharge represents chiefly effect of Pathfinder reservoir which stores 

water for use in Interstate and Fort Laramie canals.

COOPERATION. Complete records furnished by United States Reclamation Service.

Daily discharge, in second-feet, of North Platte River above Whalen, Wyo., for the years 

endmg Sept. 30, 1919 and 1920.

BIG CREEK NEAR BIG CREEK, WYO.

LOCATION. In sec. 32, T. 13 N., R. 81 W., at Big Creek ranger station, 2 miles west 

of Big Creek post office, Carbon County. No important tributary within several 

miles.

DRAINAGE AREA. 123 square miles (measured on base maps of Wyoming and Colorado; 

scale, 1:500,000).

RECORDS AVAILABLE. May 7, 1911, to June 30, 1912; April 4, 1915, to September 30, 

1920. State engineer maintained station at this point during 1913 and 1914.

GAGE. Stevens water-stage recorder installed May 13, 1918, and referred to vertical 

staff on left bank 50 feet from ranger station, used previously; inspected by 

forest ranger. Datum of gage raised 0.90 foot September 1, 1919.

DISCHARGE MEASUREMENTS. Made from bridge a quarter of a mile below gage or by 

wading.

CHANNEL AND CONTROL. Bed composed of coarse gravel and small boulders. Control at gage which is on riffle; slightly shifting. Right bank subject to overflow 

at stage of 4.2 feet.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending Sept. 30, 

1919, 3.1 feet at 4 a.m. May 30 (discharge, 515 second-feet); minimum stage, 0.501 

foot from 5 to 8 a. m. September 17 (discharge, 10 second-feet).

Maximum stage recorded during year ending September 30, 1920, 3.15 feet at 

11 p.m. June 9 and 11 (discharge, 862 second-feet); minimum discharge probably 

occurred during winter.

1913-1920: Maximum discharge, 1,300 second-feet on June 23, 1917, from comparison with flow of Encampment River; minimum discharge, 5 second-feet 

at 8 a. m. September 2, 1915 (gage height, 1.10 feet.)

ICE. Stage-discharge relation seriously affected by ice: observations discontinued 

during winter.
PLATTE RIVER BASIN. 269

DIVERSIONS. Prior to July 1, 1919, no adjudicated diversions from Big Creek above 

station in Wyoming, but below, diversions amount to 100 second-feet. In Colorado, Independence ditch diverts from Big Lake to North Platte drainage basin 

approximately 80 second-feet, usually from June 10 to July 10 each year. Storage 

filing for 27,648 acre-feet in Big Lake which supplies Independence ditch.

REGULATION. Diurnal fluctuation during spring, caused by alternate melting and 

freezing of mountain snow.

ACCURACY. Stage-discharge relation shifted during high water in 1919. Well defined 

rating curves used as follows: October 1,1918, to June 14,1919; June 15 to August 

31; September 1, 1919, to September 30, 1920; shifting-control method used 

April 24 to June 14, 1919. Operation of water-stage recorder satisfactory except as 

shown in footnote to daily-discharge table. Daily discharge ascertained by applying to rating table daily mean gage height obtained by inspection of recorder graph. 

Records for 1919 good and for 1920 excellent, except for periods of no gage 

for which they are fair.

June 13, 1918 (discharge, 1,350 second-feet); minimum stage recorded, 1.18 feet 

April 1, 1915 (discharge, 6 second-feet).

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

winter.

DIVERSIONS. Prior to July 1, 1919, adjudicated diversions of 4.3 second-feet from 

French Creek; part above station not known.

REGULATION. Alternate melting and freezing of mountain snow caused diurnal 

fluctuation during spring of year; no artificial regulation.

ACCURACY. Stage-discharge relation shifted slightly during 1919. Rating curve 

used from April 30 to May 22, 1919, well defined; applied indirectly from March 

30 to April 29. Curve used from May 13 to June 4, 1919, and from June 2 to September 30, 1920, well defined. Curve used from June 15, 1919, to June 1, 1920, 

well defined. Gage read to half-tenths during 1919 and to hundredths during 

1920, twice daily. Daily discharge ascertained by applying daily mean gage 

height to rating table. Records good, except for periods of missing gage heights, 

for which they are fair.

LA PRELE CHEEK NEAR DOUGLAS, WYO.

LOCATION. In sec. 6, T. 31 N., R. 73 W., just above high-water line of La Prele 

reservoir, 16 miles southwest of Douglas, Converse County. Nearest tributary, 

an unnamed stream 1 mile above.

DRAINAGE AREA. 136 square miles (measured on base map of Wyoming; scale, 

1:500,000).

RECORDS AVAILABLE. August 25, 1919, to September 30, 1920.

GAGE. Gurley watei-stage recorder on right bank; inspected by Wayne Kennedy.

DISCHARGE MEASUREMENTS. Made from cable 50 feet below gage or by wading.

CHANNEL AND CONTROL. Bed composed of well-compacted sand and gravel, apparently permanent. Low-water control, concrete slab 1£ feet wide near cable; 

high-water control 150 feet downstream at rapids which should be permanent. 

Banks subject to overflow at stage of 6 feet, but entire flow passes under cable.

EXTREMES OP DISCHARGE. Maximum stage during year from high-water mark of 

May il, 11.4 feet (discharge from extension of rating curve, 1,220 second-feet); 

minimum stage, 3.29 feet on October 2 (discharge, 0.4 second-foot).

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Prior to July 1, 1919, there were adjudicated diversions of 42 secondfeet from La Prele Creek above station, and 36 second-feet below.

REGULATION. None.

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

Operation of water-stage recorder satisfactory except for short periods, as shown 

in footnote to daily-discharge table. Daily discharge ascertained by applying 

to rating table daily mean gage height obtained by inspection of recorder graph. 

Records good.

COOPERATION. Field data furnished by Douglas Reservoirs Co. Check measurements made by United States Geological Survey.

LARAMIE RIVER NEAR GLENDEVEY, GOLD.

LOCATION. In SW. J sec. 25, T. 10 N., R. 76 W., at highway bridge 3 miles east of 

Glendevey, Larimer County. Nearest tributary, Nunn Creek, enters just above 

station.

DRAINAGE AREA. 101 square miles (measured on topographic map).

RECORDS AVAILABLE. June 24, 1904, to October 31, 1905; August 18, 1910, to September 30,1920. (Records for 1914, 1915, 1917, 1918, published only by State 

, engineer.)

GAGE. Bristol float-type water-stage recorder installed April 26, 1919, at right bridge 

abutment to replace Bristol pressure gage used previously; inspected by E. L. 

Farnham.

DISCHARGE MEASUREMENTS. Made from four-span bridge or by wading.

CHANNEL AND CONTROL. Bed composed of boulders and sand. Control is boulder 

riffle just below bridge; practically permanent.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1920, 

from water-stage recorder, 4.6 feet at 9 p. m. June 8 (discharge, 1,180 second-feet). 

Minimum discharge occurred during winter.

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

DIVERSIONS. Court decrees for diversion of 49 second-feet from Laramie River and 

545 second-feet from tributaries entering above. Of the latter amount 400 secondfeet represent diversions into Cache la Poudre basin. In addition, there is a conditional decree for an amount not exceeding 1,235 second-feet for diversion 

through Laramie-Poudre tunnel. During 1919 a total of 21,000 acre-feet were 

diverted into Cache la Poudre basin, and during 1920, 26,548 acre-feet.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined. Operation of water-stage recorder not satisfactory during 1919; satisfactory during 

1920. Daily discharge ascertained by applying to rating table daily mean gage 

height obtained by inspection of recorder graph. Records poor for 1919, excellent 

for 1920.

PLATTE KIVER BASIN. 299

LARAMIE RIVER NEAR JELM, WYO.

LOCATION. In sec. 15, T. 12 N., R. 77 W., at highway bridge at Boswell ranch, a 

quarter of a mile below Colorado-Wyoming line and 4 miles south of old Jelm, 

Albany County. Stuck Creek enters 1 mile upstream.

DRAINAGE AREA. 297 square miles 1 (measured on topographic maps).

RECORDS AVAILABLE. May 7, 1911, to September 30, 1920. From June 22, 1904, to 

October 31, 1905, station maintained at Decker ranch, half a mile south of State 

line. Records at two stations are comparable, as there are no tributaries or diversions of any account between them.

GAGE. Friez water-stage recorder installed April 26, 1919, on downstream side of 

center pier, and referred to same datum as staff gage at right abutment used 

previously; inspected by Mrs. C. D. Oviatt.

DISCHARGE MEASUREMENTS. Made from two-span bridge or by wading.

CHANNEL OR CONTROL. Bed composed of gravel. Control a short distance downstream; practically permanent. Left bank is overflowed at gage height 3.0 feet; 

flow passes through three well-defined high-water channels.

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

from water-stage recorder, 2.65 feet from 4 to 6 a. m. May 26 (discharge, 780 secondfeet) ; minimum discharge occurred during winter.

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

4.2 feet at noon June 8 (discharge, 3,840 second-feet); minimum discharge occurred 

during winter.

1904-1905, 1911-1920: Maximum stage in 1920; minimum discharge occurred 

during winter.

ICE. Stage-discharge relation seriously affected by ice; observation discontinued 

during winter.

DIVERSIONS. Between station near Glendevey and this station there are court 

decrees for diversion of 292 second-feet from Laramie River and 329 second-feet 

from intervening tributaries.

JlEGULATiON. Diurnal fluctuation during spring caused by alternate melting and 

freezing of mountain snow.

-ACCURACY. Stage-discharge relation practically permanent; shifted slightly during 

high water in 1920. Rating curve well defined; applied indirectly for shifting 

control May 21 to June 24, 1920. Operation of water-stage recorder fairly satisfactory, except as shown in footnote. Daily discharge ascertained by applying 

to rating table daily mean gage height as obtained by inspection of recorder graph. 

Records good, except for periods of no gage heights, for which they are fair.

 COOPERATION. Station maintained in cooperation with State engineer of Colorado.

LARAMIE RIVER AND PIONEER CANAL NEAR WOODS, WYO.

LOCATION. In sec. 36, T. 14 N., R. 77 W., at diversion dam for Pioneer canal, 2 miles 

above Woods post office, Albany County. Nearest important tributary, Fox 

Creek, enters 3 miles above.

DRAINAGE AREA. 409 square miles (measured on base map of Wyoming; scale, 

1:500,000).
PLATTE RIVER BASIN. 301

RECORDS AVAILABLE. April 16, 1912, to September 30, 1920. From July 1, 1890, 

to June 30, 1892, April 12, 1896, to September 30, 1900, and May 7 to November 

11,1911, a station was maintained at Woods Landing in sec. 11, T. 13 N., R. 77 W. 

Records not directly comparable, as Fox Creek enters between, and a few small 

ditches divert water.

GAGE. Bristol float type water-stage recorder installed May 8,1920, to replace Bristol 

pressure gage, whose datum is crest of dam; inspected by employee of Laramie 

Water Co. Gage was moved September 23,1915, to upper wing wall of headgates, 

and although actually above canal intake it still indicates flow over dam, as it is 

in pool formed by diversion dam. Gage originally at left end of dam just below 

Pioneer canal headgates. Chain in Pioneer canal is at Johnson bridge, 1$ miles 

below intake; read by employee of Laramie Water Co.

DISCHARGE MEASUREMENTS. Made from cable 2,000 feet above dam. Measurements 

of Pioneer canal made at Johnson bridge, and this quantity is subtracted from 

flow at cable to determine flow at diversion dam.

CHANNEL AND CONTROL. Channel at gage is pool formed by concrete diversion dam 

2 feet high. Control is dam itself and is permanent. Banks are high and not 

subject to overflow. Bed of canal composed of shale which changes somewhat; 

control at concrete drop, 1 mile downstream.

EXTREMES OP DISCHARGE. 1919: (Laramie River) maximum stage during year from 

water-stage recorder, 1.5 feet from noon to 4 p. m. May 23 and 24 (discharge, 720 

second-feet); minimum discharge September 28 estimated at 4 second-feet.

(Pioneer canal) maximum stage recorded, 2.28 feet May 27-29 (discharge, 148 

second-feet); minimum discharge, 0, except for small amount of leakage through

1920: (Laramie River) maximum stage during year, 3.35 feet at 3 p. m. June 

9 (discharge, 2,320 second-feet); minimum stage, 0.06 foot August 19 (discharge, 9 

second-feet).

(Pioneer canal) maximum stage recorded, 4.6 feet May 29 (discharge, 595 

second-feet); minimum stage, canal dry except for small amount of leakage 

through headgates.

1912-1920: Maximum stage during period, 4.4 feet from 8 a. m. to noon June 

23, 1917 (river discharge, 3,310 second-feet; combined discharge, 3,820 secondfeet); combined minimum discharge occurred during winter. (Pioneer canal) 

maximum stage recorded, 5.8 feet June 19, 1917 (discharge, 818 second-feet); 

minimum discharge, 0, except small amount of leakage through headgates.

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

DIVERSIONS. By decree of district court dated December 27, 1912, adjudicated 

diversions of approximately 10 second-feet from Laramie River between the 

State line and Pioneer dam, exclusive of the Pioneer canal, which has decrees 

for 282 second-feet.

REGULATION. None, as pond above dam is too small to have any appreciable effect 

on flow. Whenever canal headgates are closed discharge over dam increases.

ACCURACY. Laramie River: Stage-discharge relation practically permanent; operation of canal headgate has slight effect on gage. Operation of water-stage recorder 

satisfactory except as shown in footnote to daily-discharge table. Daily discharge 

ascertained by applying to rating table daily mean gage height obtained by inspection of recorder graph. Records good for 1919 and excellent for 1920.

Pioneer canal: Stage-discharge relation slightly shifting. Rating curve well 

defined; applied indirectly June 6-15, 1919. Gage read to hundredths once 

daily during 1919 and from May 24 to June 24, 1920; remainder of 1920 gage read 

at irregular intervals. Records good for 1919 and fair for 1920.

PLATTE RIVER BASIN. 305

LAKAMIE RIVER AT TWO RIVERS, WYO.

LOCATION. In sec. 5, T. 17 N., R. 74 W., at highway bridge at Two Rivers, Albany 

County. Nearest tributary, Little Laramie River, enters a quarter of mile below.

DRAINAGE AREA. 1,290 square miles (measured on base map of Wyoming; scale, 

1:500,000).

RECORDS AVAILABLE^ May 6, 1911, to October 31, 1912; October 1, 1913, to September 30, 1920. Station maintained by State engineer during 1913 and 1914.

GAGE. Friez water-stage recorder on left bank installed May 2, 1920, 45 feet downstream from bridge and site of Bristol gage used from 1915 to 1919; inspected by 

J. A. Doherty. Datum unchanged since 1915. Gage used in 1912 was referred 

to datum 0.74 foot lower. Gage on left bank 400 feet above bridge used during 

1913 and 1914.

DISCHARGE MEASUREMENTS. Made from cable 350 feet upstream from gage.

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

narrow limits. No well-defined control. Banks are high and not subject to 

overflow.

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

not given as gage did not operate during period of high water; minimum stagey 

0.68 foot Aug. 29 to Sept. 2 (discharge, 2 second-feet).

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

recorder, 5.75 feet for several hours on June 12 (discharge, 1,980 second-feet); 

minimum discharge probably occurred during winter.

1911-1920: Maximum stage recorded during period, 6.4 feet June 22, 1917 

(discharge, 2,600 second-feet); minimum discharge, zero, September 22 to 25,1911.

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

during winter.

DIVERSIONS. By decree of district court dated December 27, 1912, adjudicated 

diversions of 414 second-feet from Laramie River between this station and station 

near Woods.

REGULATION. Operation of ditches above station affects low-water flow.

ACCURACY. Stage-discharge relation shifted slightly during 1919. Rating curve 

used during 1919 well defined; applied indirectly for shifting control during 

high water; curve used during 1920 well defined. Staff gage read three times 

a week during greater part of 1919; operation of water-stage recorder satisfactory 

during 1920. Daily discharge ascertained by applying to rating table daily 

mean gage height obtained from inspection of recorder graph. Records fair for 

1919 and excellent for 1920.

LITTLE LARAMIE RIVER AT TWO RIVERS, WYO.

LOCATION. On line between sees. 5 and 6, T. 17 N., R. 74 W., at highway bridge

half a mile south of Two Rivers, Albany County. No tributary between station

and mouth, half a mile below. 

DRAINAGE AREA. 310 square miles (measured on base map of Wyoming; scale,

1:500,000).

RECORDS AVAILABLE. May 6, 1911, to October 31, 1912; October 1, 1913, to September 30, 1920. State engineer maintained station at this point during 1913. 

GAGE. Bristol water-stage recorder at bridge; inspected by Mrs. J. A. Doherty.

Gage used during 1913 and 1914 was 400 feet downstream and referred to different

datum.

DISCHARGE MEASUREMENTS. Made from bridge or by wading. 

CHANNEL AND CONTROL. Bed composed of sand and gravel; slightly shifting. No

well defined control. Banks not subject to overflow, except during extreme

high water. 

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

not given, as gage did not operate during period of highest water; stream practically dry after July 15. 

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

recorder, 5.7 feet at 3 p. m. June 11 (discharge, 1,280 second-feet); minimum stage,

1.75 feet September 23 (discharge, 4 second-feet).

1911-1920: Maximum discharge recorded, 1,740 second-feet on January 4,1914;

minimum discharge, zero, as river frequently becomes dry in the fall, owing to

diversion for irrigation above. 

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

during the winter. 

DIVERSIONS. Prior to July 1,1919, adjudicated diversions from Little Laramie River

of 422 second-feet between station near Filmore and this station; none below

station. t 

REGULATION . None.' 

ACCURACY. Stage-discharge relation shifted slightly. Rating curve used during

1919 well defined; applied indirectly for shifting control Oct. 1-16, 1918; curve

used during 1920 well denned; applied indirectly August 21 to September 30.

Operation of water-stage recorder not satisfactory. Daily discharge ascertained

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

of recorder graph. Records fair.

No well-defined control. Banks not subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 2.95 feet at 7.30 a. m. August 1 (discharge, 140 second-feet); minimum 

stage, 0.98 foot at 7.15 p. m. July 27 (discharge, 2.2 second-feet).

Maximum stage recorded during year ending September 30, 1920, 3.7 feet at 

4 p. m. May 7 (discharge, 227 second-feet); minimum discharge, 1.2 second-feet 

December 11 and 12, when stage-discharge relation was affected by ice.

1911-1920: Maximum stage recorded, 4.5 feet at 8 a. m. September 4, 1915 

(discharge, 350 second-feet); minimum discharge, zero, for several days during 

1913.

ICE. Stage-discharge relation slightly affected by ice.

DIVERSIONS. Prior to July 1, 1919, adjudicated diversions from Chugwater Creek 

of 73 second-feet above station and 98 second-feet below.

REGULATION. None.

ACCURACY. Stage-discharge relation shifted during 1919. Rating curve used October 1, 1918, to April 23, 1919, and curve used April 24, 1919, to September 30, 

1920, well denned below 100 second-feet; shifting-control method used February 21 

to March 24, April 11-13, and September 6-30, 1919. Discharge ascertained by 

applying daily mean gage height to rating table. Records good except for periods 

of shifting control and of missing gage heights, for which they are fair.

HORSE CREEK NEAR LAGRANGE, WYO.

LOCATION. In SW. \ SW. \ sec. 34, T. 20 N., R. 61W., 2 miles southeast of Wye-Cross

ranch and 1J miles northwest of Lagrange, Goshen County. Nearest tributary,

Bear Creek, enters 2 miles below. 

DRAINAGE AREA. 683 square miles (measured on base map of Wyoming; scale,

1:500,000). 

RECORDS AVAILABLE. November 1, 1915, to April 4, 1920. From December 1, 1911,

to December 31, 1912, fragmentary records are available at a point 1J miles downstream.

GAGE. Gurley water-stage recorder on left bank; inspected by 0. E. Miller. 

DISCHARGE MEASUREMENTS. Made from footbridge near gage or by wading. 

CHANNEL AND CONTROL. Bed composed of coarse gravel which may shift. Control

just below station at small rapids which shift between narrow limits. 

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

from water-stage recorder, 1.56 feet at 8 a. m. April 18 (discharge, 65 second-feet);

minimum stage, 0.77 foot June 8-9, 12 (discharge, 10 second-feet). 

1920: Data too few. 

1915-1919: Maximum stage recorded, 3.3 feet at 9 p. m. June 22,1918 (discharge,

366 second-feet); minimum stage, 0.75 foot at 10.30 p. m. July 12,1916 (discharge,

5.5 second-feet). 

ICE. Stage-discharge relation not seriously affected by ice except during short

periods; snow blowing in creek frequently blocks it temporarily. 

DIVERSIONS. Prior to July 1, 1919, adjudicated diversions of 1,176 Becond-feet from

Horse Creek above station, and 84 Becond-feet below. 

REGULATION. None.
PLATTE BIVEB BASIN. 317

ACCURACY. Stage-discharge relation shifted slightly during 1920; affected by snow 

and ice for short periods. Rating curve well defined; applied indirectly for shifting control January 2 to March 15, 1920. Operation of water-stage recorder satisfactory. Daily discharge ascertained by applying to rating table daily mean gage 

height obtained from inspection of recorder graph. Records good except during 

period of missing gage heights, for which they are fair.

SOUTH PLATTE RIVER AT SOUTH FLATTE, COLO.

LOCATION. In sec. 25, T. 7 S., R. 70 W., 375 feet below point where North Fork of 

South Platte enters at South Platte, Jefferson County.

DRAINAGE AREA. 2,610 square miles (measured on map in Hayden's atlas).

RECORDS AVAILABLE, March 28, 1902, to September 30, 1920. Records at Platte 

Canyon and at Deansbury, a few miles below, extend back to 1887, with the 

exception of 1893 and 1894. Earlier records, 1887-1892, were taken by State 

engineer, and records from 1895 to 1896 were taken under direction of Denver 

Power & Irrigation Co.

GAGE. Stevens water-stage recorder on right bank installed April 4. 1919, to replace 

Bristol water-stage recorder used since March 14, 1910; inspected by Mrs. Mata 

Wallbrecht. From March 28, 1902, to May 7, 1905, gage was at highway bridge, 

150 feet upstream; moved to present site at latter date and datum raised 0.80 foot 

higher.

DISCHARGE MEASUREMENTS. Made from cable near gage or by wading.

CHANNEL AND CONTROL. Bed composed of coarse sand and fine gravel; shifts. Control 35 feet downstream at well-defined rapids; shifts considerably at times. 

Banks high and not subject to overflow.

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

from water-stage recorder, 5.1 feet at 11 p. m. August 1 (discharge, 1,850 secondfeet); minimum discharge occurred during winter.

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

recorder, 1,390-second-feet at 8 a. m. June 14 and 9 a. m. June 16 (gage height, 

4.6 feet); minimum discharge occurred during winter.

1888-1892; 1895-1900; 1902-1920: Maximum gage height recorded, 7.65 feet 

(present datum) at 11 a. m. June 2,1914 (discharge, 3,200 second-feet); minimum 

discharge occurred during winter.

ICE. Stage-discharge relation seriously affected by ice.

ACCURACY. Stage-discharge relation shifting at intervals. Rating curve used from 

October 1 to December 3, 1918, and curve used August 1 to November 30, 1919, 

and August 1 to September 30, 1920, well defined; applied indirectly for shifting 

control April 1 to July 31, 1919, and March 16 to July 31, 1920. Daily discharge 

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

inspection of recorder graph. Records good.

LOCATION. In sec. 2, T. 5 NM R. 71W., at old highway bridge No. 7 in Big Thompson

Canyon, 200 yards below Loveland dam and 1$ miles east of Drake, Larimer

County. Nearest tributary, North Fork, enters at Drake. 

DRAINAGE AREA. 274 square miles (measured on topographic maps). 

RECORDS AVAILABLE. September 18, 1917, to September 30, 1920. 

GAGE. Bristol pressure gage attached to left bridge abutment; inspected by eHQ.-

ployee of city of Loveland. ,, 

DISCHARGE MEASUREMENTS. Made from single-span bridge. 

CHANNEL AND CONTROL. Channel is-pool ia which several feet of silt are deposited

and scoured out. Control is 50 feet downstream at rapids of compact gravel;

shifting at intervals. 

EXTREMES OF DISCHARGE. Maximum discharge during year ending September 30,

1919, from high-water mark, 9.5 feet at 6 p. m. July 31 (discharge not computed);

minimum discharge occurred during winter. 

Maximum stage during year ending September 30, 1920, 4.5 feet at 5 a. m,

June 9 (discharge, 1,600 second-feet); minimum discharge occuared during waiter. 

JOE. Stage-discharge relation seriously affected by ice. Winter measurements made

at section half a mile upstream. 

DIVERSIONS. Court decrees for diversions of 23 second-feet from river above station

and 2,277 second-feet below, ateo decrees for storage of 81,000 acre-feet beloir

station.
PLATTE KWER 329

. Alternate melting and freezing of mountain snow during spring causes 

diurnal fluctuation of discharge. Ne artificial regulation.

ACCURACY. Stage-discharge relation not permanent. Rating curves used March 1& 

to Jafy 31 and A«gust 1 to December 31,1919, fairly well defined below 300 secondfeet. Standard rating curve used during 1920 fairly well defined; applied indi- 

, rectly for shifting control during greater part of year. Operation of water-stage 

recorder satisfactory except as explained in footnote to table of daily discharge. 

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

obtained by inspection of recordergraph. Records fair.

COOPERATION. Field data furnished by city of Loveland. Check, measurements 

made by tTnited States Geological Survey.

NISHNABOTNA RIVER BASIN. 

WEST NISHNABOTNA RIVER AT WHITE CLOUD, IOWA.

IX)CATION. In sec. 2, T. 71 N., R. 41 W. at highway bridge, in White Cloud, Mills 

County, near crossing of Chicago, Burlington & Quincy Railroad and Wabash 

Railway, 3 miles above mouth of Silver Creek and 4 miles southeast of Malvern.

DIIAINAGE AREA. 950 square miles (measured by engineers of the Iowa State Highway Commission on United States postrroute map).

BIICO.RDS AVAILABLE. May 23, 1918, to September 30,1920.

GAGE. Chain gage attached to downstream handrail of highway bridge; read by 

Charles N. Hammack.

DISCHARGE MEASUREMENTS. Made from downstream side of Wabash Railway bridge.

CHANNEL AND CONTROL. Bed of stream composed of sand and gravel; banks subject 

to overflow. Control not well defined.

EXTREMES OP DISCHARGE. Maximum stage discharge during year ending September 

30, 1919, 7,500 second-feet October 28; minimum stage recorded 2.96 feet September 15-18 (discharge, 9 second-feet).

Maximum stage recorded during the year ending September 30,1920, 18.0 feet 

at 5.30 p. m., April 19 (estimated discharge, 12,000 second-feet); minimum discharge about 95 second-feet February 2. 

1918-1920: Maximum discharge occurred in 1920; minimum discharge in 1919.

ICE. Stage-discharge relation may be slightly affected by ice during periods of 

extreme cold weather.

REGULATION. The grist mill 200 feet above the gage may affect the stage when in 

operation. The mill dam was partly destroyed during the spring of 1919 and 

repairs were
332 SURFACE WATER SUPPLY, 1919-1920, PART VI.

ACCURACY. Stage-discharge relation changed during high water in April, 1919, and 

during heavy ice jam in March, 1920; ajso affected by dredging in channel September 25 to October 26 and November 3-24,1918. Rating curve used May 23 to 

November 3. New rating 1918 fairly well defined between 10 and 2,000 secondfeet; curve used November 25, 1918, to April 23, 1919, net well defined; curve 

used April 24, 1919, to March 13, 1920, well defined between 40 and 4,000 secondfeet; curve used March 13 to September 30, 1920, well defined between 150 and 

3,000 second-feet; extensions of curves approximate due to lack of discharge 

measurements. Gage read twice daily to hundredths. Daily discharge ascertained by applying mean daily gage height to rating table; indirect method used 

September 25 to October 26, and November 3-24, 1918. Open-water records for 

1918 and 1919, fair; for 1920, good; winter records may be affected by ice for short 

periods.

NODAWAY RIVER BASIN. 

NODAWAY RIVER AT CLARINDA, IOWA.

LOCATION. In sec. 32, T. 69 N., R. 36 W., at Fred C. Brummet highway bridge, just 

east of Clarinda, Page County, and 7 miles above mouth of East Nodaway River. 

AREA. 770 square miles (measured by engineers of the Iowa Highway 

Commission from United States post-route map; scale, 1 inch=l mile). 

RiicoRDS AVAILABLE. May 17, 1918, to September 30, 1920.

!. Chain gage attached to upstream handrail of middle span of bridge; read by 

W.'S. Grimes.

MEASUREMENTS. At medium and high stages measurements made from 

the downstream side of the bridge. Low-water measurements made by wading 

just above bridge.

CBANNEL AND CONTROL. Dredged channel with sand and clay bottom. Loam 

banks subject to overflow at 14-foot stage. No well defined control.

OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 11.25 feet April 11 (discharge, estimated, 6,060 second-feet); minimum

1.30 feet August 25 (discharge practically zero).

DISCHARGE

EXTREMES
338 SUBFACE WATER SUPPLY, 1919-1920, PART VI.

Maximum stage recorded during year ending September 30, 1920, 11.24 feet at" 

12.15 p. m. May 12 (discharge, estimated, 6,050 second-feet); minimum stage 

recorded 1.50 feet at 3 p. m. July 29 (discharge, 5 second-feet).

1918-1920: Maximum and minimum stages occurred in 1919. l

ICE. Stage-discharge relation affected by ice for short periods during extreme cold 

weather.

REGULATION. The city of Clarinda installed a new water-supply system during the 

summer of 1919 and now pumps the water supply from the river a few hundred 

feet above the gage.

Dredging operations at the mouth of West Nodaway River during August and 

September, 1920, may have materially affected the daily discharge.

ACCURACY. Stage-discharge relation may shift considerably owing-to rapid widening 

of the dredged channel and to flooding of the valley below after periods of highwater. Rating curve fairly well defined between 100 and 1,100 second-feet 

despite marked changes in channel section. Low-water rating only fair owing 

to shifting character of bottom of channel. High water rating roughly approximate, as stage-discharge relation varies with the duration of flood stage. Gage 

read to hundredths once daily and twice daily during periods of rapidly changing 

stage. Daily discharge ascertained by applying daily gage height ;to rating 

table. Record since March 20,1920, good except for days of high water. Records 

previous to that date are in doubt owing to unreliability of gage reader.

WEST NODAWAY RIVER AT VILLISCA, IOWA.

LOCATION. In sec. 28, T. 71 N., R. 36 W., at Chicago, Burlington & Quincy Railroad 

bridge (Clarinda branch) half a mile west of Villisca, Montgomery County, and 

1 mile above junction with Middle Nodaway River.

DRAINAGE AREA. 350 square miles (measured by engineers of the Iowa State Highway Commission from United States post-route map; scale, 1 inch = 1 mile).

RECORDS AVAILABLE. May 20, 1918, to September 30, 1920.

GAGE. Chain gage attached to upstream guardrail of bridge; read by J. S. Dunn.

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

CHANNEL AND CONTROL. Bed composed of sand and mud; no well-defined control. 

Banks were overflowed frequently prior to dredging of new channel.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30,1919,16.40 feet April 23 (discharge, 3,780 second-feet); minimum stage recorded, 

1.51 feet October 9, 12, and 14 (discharge, about 1 second-foot).

Maximum stage recorded during year ending September 30, 192ft, 11.70 feet 

at 7.20 a. m. July 12 (discharge, 1,330 second-feet); minimum stage recorded 1.70- 

feet at 7.20 a. m. September 29 (discharge, 7 second feet).

1918-1920: Maximum stage occurred in 1919; minimum stage 1.51 feet several 

times in September and October, 1918 (discharge, about 1 second-foot).

ICE. Stage-discharge relation affected by ice during periods of extreme cold weather.

ACCURACY. Stage-discharge relation uncertain* after April 21, 1919, owing to dredging operations; affected by ice. Rating curve used- May 20, 1918, to April 20, 

1919, well defined between 10 and 2,000 second-feet; curve used February 9 to 

September 30, 1920, fairly well defined between 5 and 500 second-feet; poorly 

defined outside these limits. Shifting-control method used April 21, 1919, to 

February 8, 1920. Gage read to hundredths once daily. Dqily discharge ascertained by applying daily gage height to rating table except for periods affected 

by ice or dredging operations for which it was obtained by correcting daily gage 

height by means of discharge measurement, observer's notes, and Weather records. 

Open-water records May 20, 1918, to April 21, 1919, and February 9 to September 

30, 1920, fair; records April 22, 1919, to February 8, 1920, roughly approximate.

DIVERSIONS. Some irrigation diversions from Republican River in western Nebraska.

ACCURACY. Stage-discharge relation fairly permanent except during periods of high 

water and ice. Rating curves used as follows: August 27 to September 19, 1919, 

and May 14 to September 30, 1920, fairly well denned between 100 and 1,600 

second-feet; September 20, 1919, to May 13, 1920, fairly well defined below 1,600 

second-feet. Rating curves have been extended above these limits for high stages. 

Gage section painted on pier read to tenths and low-water section on left bank 

read to hundredths twice daily during open-water period and daily to water 

surface during ice period. Daily discharge ascertained by applying mean daily 

gage height to rating table except for periods when stage-discharge relation was 

affected by ice. Mean discharge for these periods based on observer's notes and 

weather records. Open-water records fair except for extremely high stages, for 

which the rating curves are poorly denned; winter records subject to considerable 

error.

KANSAS RIVER BASIN. 347

REPUBLICAN RIVER AT WAKEFIELD, KANS.

XOCATION. In NE. \ sec. 5, T. 10 S., R. 4 E., at highway bridge 1,000 feet north of 

Union Pacific Railroad station at Wakefield, Clay County. No important 

tributaries enter between this point and the mouth near Junction City, 16 miles 

(air line) downstream, where Republican and Smoky Hill rivers unite to form 

Kansas River.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. June 21, 1917, to September 30, 1920.

 GAGE. Chain gage bolted to upstream guard timber of highway bridge in center of 

middle span; read by S. R. Winsor. A vertical staff, graduated from 13.55 to 

20.3 feet, spiked to a large cottonwood tree on right bank 25 feet downstream 

from bridge, used during high stages.

DISCHARGE MEASUREMENTS. Made from downst/eam side of highway bridge or by 

wading.

 CHANNEL AND CONTROL. Bed is sandy, shifting, and clear of vegetation; stagedischarge relation, however, has not been affected. River is confined within 

fairly high banks; bankful stage is about 11 feet. Left bank is overflowed at 

high stages and river spreads out over .valley floor to a width of 2 or 3 miles. Right 

bank at gage is high and not subject to overflow. Channel bends slightly about 

a quarter of a mile upstream, and is straight for a long distance downstream 

from the gage. A sand bar formed under the bridge at chain gage during the 

summer of 1920 and prevented observer from obtaining readings to water surface 

July 20 and August 3-9, 1920.

EXTREMES OF DISCHARGE. Maximum stage recorded during years ending September 30,1919 and 1920,11.05 feet at 6.30 p. m. June 10,1919 (discharge, 18,200 

second-feet); minimum stage, 2.0 feet at 8.30 a. m. September 17, 1919 (discharge, 

80 second-feet).

1917-1920: Maximum stage recorded, same as given above; minimum stage, 

1.6 feet at 7 p. m. September 12, 1917 (discharge, 40 second-feet).

During the flood of June, 1915, the river rose to within a few feet of the bridge 

floor, which is approximately at gage height 22£ feet, and the entire valley was 

flooded.

ICE. Stage-discharge relation affected by ice.

REGULATION. Flow is affected by regulation of a dam at Clay Center.

ACCURACY. Stage-discharge .relation permanent; rating curve well defined. Gage 

read to quarter-tenths twice daily during open-water periods and once daily to 

surface, except as noted, during ice periods. Daily discharge ascertained by 

applying mean daily gage height to rating table, except for periods when stagedischarge relation was affected by ice. Observer's notes and weather record 

followed as basis of computing mean discharge for these periods and determinations compared with other records in the Kansas River basin. Discharge estimated August 3-9, 1920, from observer's notes, as sand bar under chain gage 

prevented readings to water surface. Records for open water excellent; winter 

records subject to error.

KANSAS RIVER AT OGDEN, EASTS.

LOCATION. In SE. \ sec. 12, T. 11 S., R. 6 E., at highway bridge three-fourths mile 

southeast of Ogden, Riley County. Sevenmile Creek enters from north onefourth mile upstream; Clark Creek enters from south 2 miles upstream. Smoky 

Hill and Republican rivers unite near Junction City, 6 miles by direct line (10* 

miles by river) upstream, to form Kansas River. Camp Funston is at Ogden 

Flats, along Kansas River, 1J miles upstream.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. June 19, 1917, to September 30, 1920.

GAGE. Chain gage bolted to upstream handrail of highway bridge in center of first 

span from right bank (south span); read by Arthur Estes. On April 22, 1919, a 

vertical staff, graduated from 21.0 to 29.8 feet, for use during high stages, was 

spiked to the north side of an aspen on west side of road to highway bridge 220s 

feet south of bridge.

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

wading.

CHANNEL AND CONTROL. Bed composed of sand; control somewhat shifting. A 

stone jetty on right bank about 50 feet downstream from bridge partially controls 

flow at low stage. There are old bridge members in the channel below the bridge,, 

the remains of an old bridge that was washed out. Bankful stage occurs at about 

stage of 18 feet and both banks are overflowed considerably at flood stage. Drift 

that had been gradually collecting about the first pier from the left (north) bank, 

increased rapidly after the high water in March, 1919, and ionned an effective 

barrier to flow in the north channel.
KANSAS RIVER BASIN. 351

EXTREMES OF DISCHARGE. Maximum stage recorded during years ending September 

30,1919 and 1920,15.85 feet at 1.40 p. m. March 16,1919 (discharge, 25,300 secondfeet); minimum stage, 4.55 feet at 7.20 a. m. October 7, 1918 (discharge, 475 

second-feet).

1917-1920: Maximum stage recorded, same as given above; minimum stage 

recorded during open-water period, 4.4 feet at 5.30 p. m. October 23, 1917, and 

3.8 feet at 7.15 p. m. August 2, 1917 (discharge, 230 second-feet).

ICE. Stage-discharge relation affected by ice. Maximum ice thickness recorded for 

winter 1918-19, 9 inches January 5,1919; for winter 1919-20, 6 inches December 

13, 1919.

REGULATION. Flow affected somewhat by mill and power regulation on the tributaries of Kansas Elver.

ACCURACY. Stage-discharge relation changes during high stages, necessitating frequent changes in rating curves. Eating curves used as follows: October 1, 1917, 

to March 15, 1919, well denned below 2,400 second-feet and fairly well denned 

above 2,400 second-feet: March 16 to June 12 and July 27 to September 30, 1919, 

fairly well denned below 16,000 second-feet, with curve extended to cover higheststages; June 13 to July 26, 1919, indirect method for shifting control; October 1,

1919. to April 13, 1920, poorly denned; April 14 to June 29, 1920, fairly well denned; June 30 to August 2,1920, indirect method for shifting control; August 3-20,.

1920. poorly denned; August 21 to September 30,1920, poorly denned. Gage read 

to quarter-tenths twice daily during open-water periods, and once daily to water' 

surface, except as noted, during ice periods. Daily discharge ascertained by 

applying mean daily gage height to rating table except for periods when stagedischarge was affected by ice. Mean discharge for these periods based on 

notes and weather records and determinations compared with other records in 

Kansas Eiver basin-. Open-water records for year ending September 30, 1919, 

good except for extreme high stages which are fair; open-water records October,, 

1919, to February, 1920, fair; March to June, 1920, good; July, fair; August and 

September, good; winter record subject to error.

KANSAS RIVER AT WAMEGO, KANS.

LOCATION. In SE. \ sec. 9, T. 10 S., R. 10 E., at highway bridge on Main Street, 

Wamego, Pottawatomie County. Antelope Creek enters from south, 3 miles 

upstream, and Vermilion River enters from north, 7 miles downstream.

DRAINAGE AREA. 53,200 square miles (authority, United States, feather Bureau).

RECORDS AVAILABLE. January 1, 1919, to September 30, 1920. Complete United 

States Weather Bureau gage-height record for this station covers the following 

periods: June 15 to July 31, 1914; January 1 to August 25, 1915; January 1 to July 

31, 1916-1918; January 1, 1919, to September 30, 1920. 1

GAGE. United States Weather Bureau chain gage, bolted to downstream side of 

second span of highway bridge, center of span. On August 20, 1919, the old 

chain gage was replaced by a new chain gage for the Weather Bureau by engineer^ 

of the United States Geological Survey. No change in gage datum. Gage read 

by Frank B. Axtell during 1919 and by B. A. Larson beginning January 1, 1920.

DISCHARGE MEASUREMENTS. Current-meter measurements at this station by United 

States Geological Survey began in 1919; made from downstream side of highway 

bridge and referenced to United States Weather Bureau chain gage.

CHANNEL AND CONTROL. Bed composed of sand, somewhat shifting. Channel is 

wide and nearly straight in vicinity of gage. A wooded island about one-fourth 

mile upstream divides the flow in the approach channel, and affects the distribi|- 

tion of velocities past the highway bridge, especially at low and medium stages. 

At low stages, practically the entire flow is confined to the right channel past thje

1 See U. S. Dept. Agr. Weather Bureau, Daily river stages at river gagestations on the principal xiver& 

of the United States, published annually.
KANSAS BIVEE BASIN. 355

island and passes the highway bridge in several channels at varying angles. The 

stone piers of the six-span highway bridge affect the measured velocities, especially 

at high stages. Both banks are high; bankful stage about 15 feet. Eight bank 

is overflowed at extreme high stages.

EXTREMES OF STAGE. United States Weather Bureau record, 1914-1920: Maximum 

stage recorded, 20.3 feet, June 20, 1915; minimum stage recorded, 1.5 feet, February 22,1918.

EXTREMES OF DISCHARGE. Maximum stage recorded during years ending September 

30,1919 and 1920,14.6 feet at 7 a. m. June 12,1919 (discharge, 43,000 second-feet); 

minimum discharge, 84(1 second-feet August 9, 1920.

ICE. Stage-discharge relation affected by ice.

REGULATION. Flow is affected by power regulation on tributaries upstream.

ACCURACY. Stage-discharge relation fairly permanent. Observed velocities of 

current-meter measurements at low and medium stages in 1919 and 1920 were 

corrected for varying angles of flow observed at time of measurement (see " Channel and control"). The! exact position of the rating curves developed, especially 

for low stages, depends largely upon the correctness of the velocity coefficients 

use<l. Rating curves u|sed as follows: January 23 to September 30, 1919, well 

denned between 1,300 ajnd 30,000 second-feet; October 1, 1019, to September 30, 

1920, well denned abo^e 1,500 second-feet.

Gage read to tenths once daily prior to June 1, 1919; twice daily after that date 

and occasionally to half-tenths beginning August 20, 1919. Daily discharge 

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

of ice effect. Estimate^ of flow during ice period, December 4 to 27, 1919, 

based on observer's notes and weather records and by comparison of records of 

other stations in Kansas River basin.

Records January to & larch, 1919, fair; April to August, 1919, good; September 

to November, 1919, January and February, 1920, fair; March to September, 1920, 

good; winter records suoject to considerable error.

KANSAS RIVER AT TOPEKA, KANS.

LOCATION. Midway between Topeka Sand Co.'s sand dip and Fowler's sand dip, 

between foot of Topeka Avenue and Harrison Street, 300 feet downstream from 

Chicago, Rock Island & Pacific Railway Co.'s bridge and 1,900 feet upstream from 

Melan arch highway bridge on Kansas Avenue, Topeka, Shawnee County. Reinforced-concrete well and shelter for water-stage recorder is in high-water portion 

of channel on right bank, 50 feet north of concrete levee. Soldier Creek enters 

1J miles downstream.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 24 to August 31, 1904, and June 12, 1917, to September 

30, 1920.

GAGES. Gurley long-distance water-stage recorder used beginning October 2, 1918; 

outside staff gage read by E. F. Charlton, William Happe, and beginning July 1, 

1920, by H. N. Richardson. For history of previous gages see Water-Supply 

Paper 476.

DISCHARGE MEASUREMENTS. Made from downstream side of Sardou Avenue highway 

bridge, about 1 mile downstream from site of water-stage recorder, for low and 

medium stages! and from Brickyard highway bridge, 3 miles upstream from gage, 

for high stages. Velocity observations made at Sardou Avenue highway bridge 

are corrected for angle by coefficients determined at time of measurement.

CHANNEL AND CONTROL. Bed composed of sand and silt. The Melan bridge acts as a 

partial control for the stage-discharge relations at all stages, and other bridges in this 

vicinity undoubtedly influence the stage-discharge relation at high stages. Both 

banks have levees protecting Topeka, and the stream is confined within these 

at all stages. Bankful stage occurs at about stage of 21 feet. During January 

and February, 1918, considerable piling was removed from under the Melan 

bridge by the North Topeka Drainage district and South Side Levee district 

No. 6, for the purpose of increasing the scouring effect and carrying capacity of 

the river channel during high-water periods.

EXTREMES OP DISCHARGE. Maximum stage recorded during years ending September 

30,1919 and 1920, 20.0 feet at midnight, March 16, 1919 (discharge, 68,000 second-
ANSAS 359

feet); minimum stage recorded, 3.25 feet at 7.20 a. m. October 10, 1918 (discharge, 

740 second-feet).

1917-1920: Maximum ^tage recorded, same as given above; minimum stage 

recorded, 3.15 feet at 7,30 a. m. September 28,191$ (discharge, 705 second-feet).

ICE. Stage-discharge relatiorj seriously affected by ice. The activities of the sand 

companies in the vicinityl of the gage tend to keep the channel partly open during 

the winter except in extrjemely cold weather. Maximum ice thickness recorded 

during winter of 1918-19, |14 inches, January 7, 1919; during winter of 1919-20, 12 

inches, December 17, 1919.

REGULATION. None.

ACCURACY. Stage-discharge Relation fairly permanent. Rating curves used as follows: October 1, 1918, to December 23, 1918, fairly well defined; January 20 to 

November 29,1919, well defined above 1,000 second-feet, fairly well defined below 

this limit; February 5 to September 30, 1920, well defined. Staff, gage read to 

quarter-tenths twice daLy during open-water periods and once daily to water 

surface during ice periods. Long distance water-stage recorder records graphically half-tenth foot charges in stage. The intake pipe at times became clogged 

with fine silt, especially during 1919, that impaired the reliability of the graphic 

records. Additional intakes provided with clean-out devices were installed 

during 1919 to remedy tiis. The observer's gage record afforded a close check 

on the graphic record, which was of great value in recording rapidly rising and 

falling stages. Daily discharge ascertained-by applying mean daily gage height 

to rating table except for periods of ice effect for which mean discharge was 

determined from observer's notes, weather records, and by general comparison of 

records of other stations in Kansas River basin. For a few days, as noted in 1920, 

when stage changed very rapidly, the mean daily discharge was ascertained by 

applying hourly gage heights to rating table. Open-water records good; winter 

records fair.

GENERAL. On September 30, 1918, the United States Weather Bureau discontinued 

readings from their chain gage at Melan bridge, which had been in use since 

August 1,1904, and desigr ated the Geological Survey gage as their official river gage 

at Topeka for flood forecast service. The receiver of the long-distance waterstage recorder is in the Weather Bureau office, 1 mile distant. The sender at the 

gaging station operates the receiver electrically by means of a leased telephone 

line. The records from this long-distance water-stage recorder are used by the 

Weather Bureau in connection with its flood forecast service for Kansas Valley. 

The Weather Bureau cl lain gage was removed from Melan bridge March 11,1919. 

Comparison of the readings from the Weather Bureau chain gage with corresponding readings from Abater-stage recorder showed that the two gages read practically the same at low &nd medium stages, although they were not set to the 

same datum.

KANSAS RIVER AT BONNER SPRINGS, XANS.

LOCATION. In NW. \ sec. 32, T. 11 S., R. 23 E., at highway bridge at Bonner Springs, 

Wyandotte County. Wolf Creek enters from north just above Atchison, Topeka, 

& Santa Fe Railway bridge half a mile upstream. Kansas River joins Missouri 

River at Kansas City, 18 miles downstream. Station is above backwater influence 

of Missouri River.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. July 8, 1917, to September 30, 1920.

GAGE. Chain gage on upstream handrail of highway bridge in center of second span 

from left bank, read by B. L. Rehm except September 16, 1919, to August 2, 

1920, when it was read by J. T. Wright.

DISCHARGE MEASUREMENTS. Made from downstream side of highway bridge.

CHANNEL AND CONTROL. Bed composed of sand, somewhat shifting; flow confined 

to one channel up to bankful stage. Left bank is high and fairly steep; right 

bank is subject to overflow at stage of about 18 feet. An earth levee protects the 

right bank from excessive overflow. The river passes under the Atchison, 

Topeka & Santa Fe Railway bridge and pile trestle on right bank at a slight 

angle but straightens out half way between this bridge and the highway bridge 

and is normal to the highway bridge and for some distance downstream. Considerable drift lodged around the third pier of the highway bridge from left bank 

during the high water in March, 1939. This grew to an obstruction of large size 

with each succeeding rise. The drift was removed during the last of June, 1919. 

It caused considerable scouring of channel around bridge pier and impaired the 

accuracy of discharge measurements made during this period.
KANSAS MVEB BASIN. 363

EXTREMES OF DISCHARGE. Maximum stage recorded during years ending September 

30, 1919 and 1920, 22.2 feet at 5.30 p. m. March 17, 1919 (discharge, 109,000 

second-feet); minimum stage recorded, 3.2 feet at 8 a. m. October 1, 1918 (discharge, 860 second-feet).

1917-1920: Maximum stage recorded, same as given above; minimum stage 

recorded, 3.15 feet at 6 p. m. September 30, 1918 (discharge, 805 second-feet).

ICE. Stage-discharge relation affected by ice.

REGULATION.- Flow is affected somewhat by regulation of dam of Boweisock Mills 

& Power Co. at Lawrence.

ACCURACY. Stage-discharge relation practically permanent. Eating curve used 

October 1, 1918, to September 30, 1919, fairly well denned between 1,000 and 

70,000 second-feet; curve used October 1, 1919, to September 30, 1920, well 

denned. Gage read to quarter-tenths twice daily during open-water periods 

and once daily to water surface, except as noted, during ice periods. Daily 

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

for periods of ice effect for which it was determined from observer's notes, weather 

records, and by general comparison of records of other stations in Kansas River 

basin. Open-water records good except for extreme high stages for which they 

are fair; winter records subject to error.

SHORT HILL RIVER AT ELLSWORTH, KANS.

LOCATION. In SE. i sec. 20, T. 15 S., B. 8 W., at Pioneer Memorial highway bridge 

at Ellsworth, Ellsworth County. Turkey Creek enters from south 2 miles upstream; Oxide Creek enters from south 2 miles downstream.

DRAINAGE AREA. 7,980 square miles.

RECORDS AVAILABLE. April 17, 1895, to October 31, 1905, and July 23, 1918, to 

September 30, 1920.

GAGE. rChain gage fastened to upstream concrete handrail in center span of reinforced concrete arch bridge, read by E. A. Forkner. Staff gage in two sections,, 

fastened to pier of old highway bridge on south bank, used from 1895 to 1905; set 

at different datum.

DISCHARGE MEASUREMENTS. Made from downstream side of highway bridge or bjr 

wading.

CHANNEL AND CONTROL. Bed composed of sand, shifting. Channel is straight in 

vicinity of gage, left bank high. Right bank low and is overflowed at high stage. 

Bank-full stage at gage-height about 20 feet. A sand dip began operations in 

May, 1920, about 200 feet downstream from gage. During the summer it was 

relocated a short distance below the highway bridge. The operation of this sand 

dip probably affected the stage-discharge relation at medium stage. A water 

main across the.river just below the highway bridge acts as the control for lowstages.
KANSAS RIVER BASIN. 367

EXTREMES OP DISCHARGE. Maximum stage recorded during years ending Spetember 

30, 1919 and 1920, 11.4 feet at 7.30 a. m. May 5 (discharge, 6,320 second-feet); 

minimum stage, 1.8 feet August 3-6, 1920 (discharge, 8 second-feet).

1895-1905; 1918-1920: Maximum stage recorded, 16.55 feet (gage at old highway bridge) July 5,1895 (discharge, 21,000 second-feet); minimum stage recorded, 

0.5 foot, August 4-7, 1901 (discharge, 5 second-feet).

ICE. Stage-discharge relation seriously affected by ice. Maximum ice thickness 

recorded during winter of 1918-19, 12 inches, January 8-11, 1919; during winter 

of 1919-20, 6J inches, December 15, 1919.

REGULATION. None.

ACCURACY. Stage-discharge relation fairly permanent. Rating curves used as 

follows: October 1, 1918, to September 30, 1919, well defined between 100 and 

1,400 second-feet, poorly defined below and above these limits; October 1, 1919, 

to July 18, 1920, well defined; July, 1920, to September 30, 1920, fairly well 

defined. No high-water measurements have been made since station was reestablished. Rating curve for 1919 has been extended to cover high stages by 

comparison with stage-discharge relation defined by measurements made during 

1899-1903 at this location. Chain gage read to quarter-tenths .twice daily during 

open-water season and once daily to water surface during winter periods. Daily 

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

for periods when stage-discharge relation was affected by ice. Mean discharge 

for these periods based on observer's notes and weather conditions. Records for 

open water October, 1918, to February, 1919, May, August, and September, 1919, 

fair; March, April, June, and July, 1919, good; October, November, 1919, March 

to June, 1920, good; July to September, 1920, fair; winter records roughly approximate. Daily discharge from December, 1919, to February, 1920, determined 

from open-water rating, and may be subject to error owing to backwater caused 

by ice for which no information is available.

SMOKY HILL RIVER NEAR ABILENE, EANS.

LOCATION. In SE. i sec. 23, T. 13 S., R. 1 E., at highway bridge at Sand Springs, 

4 miles west of Abilene, Dickinson County. Holland Creek enters from south 

3 miles downstream. Station is 5 miles in a direct line (9 miles by river) below 

mouth of Solomon River.

DRAINAGE AREA. 18,700 square miles (authority, U. S. Weather Bureau).

RECORDS AVAILABLE. United States Geological Survey: June 18, 1918, to September 

30, 1920. U. S. Weather Bureau: November 22, 1904, to June 18, 1918. 1

GAGE. U. S. Weather Bureau chain gage, fastened to downstream handrail of highway bridge 56 feet from left abutment. Gage installed July 6, 1917, by Montrose 

W. Hayes, meteorologist, United States Weather Bureau by levels from benchmarks; replaced gages previously used at this station. On September 4, 1919, 

the United States Geological Survey painted a vertical staff gage, graduated 

from 17 to 25.3 feet on concrete reservoir at Pand Springs, 250 feet upstream from 

chain gage, southwest of pump house; a second high- water section, 26.9 to 30 feet, 

was painted on northwest corner of pump house ; both sections set by levels from 

benchmark. Gage read by T. W. Sherman until September 30, 1919, by Mrs. 

R. A. Grubbs beginning October 1, 1919.

DISCHARGE MEASUREMENTS. Made from downstream side of highway bridge.

CHANNEL AND CONTROL. Sand and silt. Control fairly permanent during 1919, 

not permanent during 1920. Channel for a long distance up and downstream 

from the gage is of uniform cross section and nearly straight with well-distributed 

velocity. Bankful stage at gage height about 22 feet. Both banks are overflowed 

at extreme high stages, the right bank for a considerable distance. Overflow 

on the left bank is controlled largely by railroad embankments that parallel 

the river for some distance. Until 1920 the Riverside Light, Power & Ga& Co.'s

1 See U. S. Dept. Agr. Weather Bureau, " Daily river stages at river gage stations on the principal rivers 

of the United States," published annually.
KANSAS RIVES,

dam south of Abilene, about 10 miles dWnstreaai from gage, 

within a mile of Sand Springs and, it was further stated by officials of the company, th£,t in the history of the dam backwater had never reached as far as Sand 

Springs. Certain changes in the maintenance of the dam made during 1920 

appear to have materially affected the stage-discharge relation for this station, 

necessitating several changes in rating as developed from discharge measurements,

EXTREMES OF DISCHARGE. Maximum stage recorded during years ending September 

30, 1919 and 1920, 21.3 feet at 6 p. m., June 14, 1919 (discharge, 12,800 secondfeet); minimum stage, 0.05 foot, December 13, 1918 (discharge, 77 second-feet). 

1918-1920: Maximum and minimum stages recorded, same as given above. 

1904-1918: United States Weather Bureau record: Maximum stage, recorded, 

24.0 feetf June 11, 1903 (discharge, not determined); minimum stage recorded, 

 0.5 foot, July 12, 1911, and other dates (discharge, not determined). Highwater raaik, 28.4 feet, May 29,1903, notch cut in root on south side of cottonwood 

tree by observer, on south side of Golden Belt highway, directly across pump 

house; determined by levels from benchmarks by M. W. Hayes, meteorologist, 

United States Weather Bureau in 1917. (A high-water mark of 27.3 feet for this 

date has been given by United States Weather Bureau in several issues of " Daily 

river stages.")

ICE. Stage-discharge relation affected by ice. Sand Springs, which furnish the 

water-supply for Abilene, flow into the river a short distance upstream from gage 

and tend to keep river open at gage except during severe weather.

REGULATION, Flow is affected by regulation of mill dams on Smoky Hill River 

and its principal tributaries upstream.

ACCURACY. Stage-discharge relation fairly permanent during year ending September 

30, 1919, not permanent after about April 14, 1920 (see "Channel and control"). 

Rating curves and special computations used as follows: October 1,1918, to December 31,1919, well defined between 200 and 1,500 second-feet, and between 2,500 

and 8,000 second-feet; poorly defined below 200 second-feet; above 8,000 secondfeet curve developed from study of high-water measurement made June 13,1919, 

and area and velocity curves; January 1 to April 14, 1920, poorly defined; April 

15 to May 27, 1920, fairly well defined; May 28 to July 18, 1920, indirect method 

for shifting control used; July 19 to August 27, fairly well defined between 100 

and 1,000 second-feet; August 28 to September 30, 1920, poorly defined. Chain 

gage read to quarter-tenths twice daily. Daily discharge ascertained by applying 

mean daily gage height to rating table except when stage-discharge relation .was 

affected by ice. Mean discharge for these periods based on observer's notes and 

weather records and by comparison with other records on streams in Smoky Hifl 

River basin. Records for open-water periods during 1919, good; during 1920, 

fair; winter records roughly approximate.

SALINE RIVER AT TESCOTT, KAHS.

LOCATION. In SE. i sec. 16, T. 12 S., R. 5 W., at highway bridge, one-quarter 

mile downstream from remains., of an old dam, half a mile south of Tescott, 

Ottawa County. Table Rock Creek enters from south 4 miles upstream. Dry 

Creek enters from north half a mile downstream. Saline River is tributary to 

Smoky Hill River, 24 miles in a direct line downstream.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 3, 1919, to September 30, 1920.

GAGE. Chain gage bolted to downstream handrail of highway bridge; read by W. A. 

Scidmore.

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

wading.

CHANNEL AND CONTROL. Bed composed of sand and silt, probably shifting. Channel 

is fairly straight in vicinity of gage; both banks are steep and heavily wooded: 

one channel for all stages. Bank-full stage about 25 feet. At extreme high 

stages river overflows right bank some distance upstream from gage.

EXTREMES OP DISCHARGE. Maximum stage recorded during period of records, 16.4 

feet at 6 p. m. September 23,1919 (discharge, 2,250 second-feet); minimum stage, 

1.6 feet at 9.30 a. m. September 25, 1920 (discharge, 5 second-feet).

ICE. Stage-discharge relation affected by ice.

REGULATION. Flow is affected by regulation of mills upstream at Shady Bend and 

Lincoln.

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

denned between 8 and 1,500 second-feet; extended above 1,500 second-feet. 

Gage read to half-tenths twice daily until June 23, 1920, once daily thereafter. 

Daily discharge ascertained by applying mean daily gage height to rating table, 

except when stage-discharge relation was affected by ice or backwater. Mean 

discharge for these periods based on observer's notes and weather records and OE 

comparison with other records on streams in Smoky Hill River basin. Open-
KANSAS EJVBE BASIN. S75

water Records good, except December, 1919, January and February, 1920, which 

are fair> Determinations of discharge for these months subject to considerable

error ojring to incomplete notes regarding ice.

SOUTH FORK OF SOLOMON RIVER AT ALTON, KANS.

LOCATION. In SW. £ sec. 12, T. 7 S., R. 15 W., 1,000 feet downstream from remains 

of an old mill dam, three-fourths mile south of Alton, Osborne County.

DRAINAGE AEEA. Not measured.

RECORDS AVAILABLE. August 31, 1919, to September 30, 1920.

GAGE. Staff gage painted on downstream cylinder bridge pier on north side of second 

span frorn left bank, with low-water section fastened to form work at base of 

same pie^; high-water section, graduated from 13.0 to 23.0 feet, painted on downstream side of left bridge abutment. Gage read by James K. Thompson.

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

wading.

CHANNEL ANp CONTROL. Bed composed of sand; control probably shifting for low 

stages. Two channels at low stages; one for medium and high stages. Banks 

are steepj in the vicinity of the gage and are not overflowed. Right bank is 

wooded. Bankful stage about 21 feet. Meandering stretch of stream some distance downstream from gage, where banks are lower, forms the control for high 

stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during period of records, 19.5 

feet (crest) at 3 a. m. September 19, 1919 (discharge, 9,340 second-feet, based on 

extension of rating curve); minimum stage, 0.55 foot, August 3, 1920 (discharge*, 

1 second-foot).

ICE. Stage-discharge relation affected by ice. Maximum ice thickness recorded 

winter 1919-20, 10 inches, December 13, 1919.

REGULATION.- None at present.

ACCURACY. Stage-discharge relation for low stages changed considerably after the 

high wat^r in September, 1919; fairly permanent since then. Rating curve used 

August 31, 1919, to September 19, 1919, poorly defined, extended for high stages; 

curve used September 20, 1919, to September 30, 1920, well defined below 250 

second-fefet, fairly well defined between 250 and 2,500 second-feet. Gage read to 

quarter-tenths twice daily during open-water periods; once daily to water surface, 

except as; noted, during winter. Daily discharge ascertained by applying mean 

daily gage height to rating table except when stage-discharge relation was affected 

by ice. Mean discharge for these periods based on observer's notes and weather 

records and on comparison with records for North Fork of Solomon River at Kirwin, Kans. Open-water records for September, 1919, poor; October and November,

1919. fair; December, 1919, poor; January to March, 1920, fair; April to September,

1920. good. Records when stage-discharge relation was affected by ice, roughly 

approximate.

SOLOMON RIVER NEAR BENNINGTON, KANS.

LOCATION. In SW. J sec. 28, T. 11 S., R. 3 W., at Darling Point highway bridge, 2 

miles north and 3J miles west from Bennington, Ottawa County, and 5 miles southeast of Minneapolis. Salt Creek enters from west 1J miles upstream.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 1, 1917, to June 23, 1919, when station was discontinued; record continued at Niles (p. 382).

GAGE. Vertical staff painted on downstream cylinder pier of highway bridge on 

right bank, with vertical staff, fastened to same pier, for low stages.

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

wading.

CHANNEL AND CONTROL. Sand and silt, somewhat shifting. Channel is narrow and 

winding, with steep banks, heavily wooded. One channel except at extreme 

high stage, when overflow occurs through a draw 500 feet west of the bridge. 

Stream is at a slight angle to bridge. Bankful stage about gage height 25 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during period, 22.0 feet at noon 

June 15, 1919 (discharge, not determined; see record for Solomon River at Nilea)j 

minimum stage recorded during period, 1.55 feet at 5.40 p. m. October 23, 1918. 

(discharge, 23 second-feet).

1917-1919: Maximum stage recorded, same as given above; minimum stage, 

recorded, 1.35 feet November 22, 1917 (discharge, 14 second-feet).

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. Flow noticeably affected by regulation of mill dams upstream on SoK 

omon River and the North and South forks; the nearest mill dam is at Minneapolis.

ACCURACY. Stage-discharge relation was fairly permanent until high water of May,. 

1919, when it appears to have changed. Rating curve used to May 14, 1919, 

fairly well denned below 2,100 second-feet, extended to cover high stages. Dailydischarges beginning May 15, 1919, are given with records for Solomon River at 

Niles. Gage read to quarter-tenths twice daily during open-water season, oftenerduring extreme high-water periods, and once daily to water surface during iceperiods. Daily discharge ascertained by applying mean daily gage height to.

charge ifor these periods based on observer's notes and weather records and by 

comparison with records for other stations in upper Kansas River basin. Records 

for open-water periods good, except for October, 1918, and May, 1919, for which 

they are fair; winter records subject to error.

SOLOMON BITER AT NItES, KAKS.

LOCATION. In NW. J sec. 31, T. 12 S., R. 1 W., at highway bridge three-fourths mile

west of Niles, Ottawa County. Station is 7 miles upstream in a direct line (15

miles by river) from confluence with Smoky Hill River. 

DRAINAGE AREA. Not measured. 

RECORDS AVAILABLE. May 6, 1897, to November 30, 1903, and May 15, 1919, to

September 30, 1920. October 1, 1917, to June 23, 1919, records were collected

near Bennington, Kaiis. 

GAGE. Chain gage bolted to downstream handrail of new highway bridge; read by

Miss Mamie Kenison. Wire gage, used from 1897-1903, spiked to floor of old

highway bridge; set at a different gage datum. >
KANSAS -MVEB BASIN. 383

DISCHARGE MEASUREMENTS. Made from downstream side of highway bridge..

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

One chanjnel except at extreme high stages, when river overflows right bank some 

distance ^ipstream and flows through a draw west of the bridge. Channel immediately upstream from bridge is fairly straight, downstream it curves to east, 

consequently current is not normal to bridge, especially at low and medium stages. 

Velocity observations are corrected by angle coefficients observed at time of measurement. Both banks are fairly high and heavily wooded in the vicinity of the 

gage, the trees and branches forming obstructions to free flow at high stages. 

When flood stages occur on Smoky Hill River and Solomon River is also at high 

stage, thq stage-discharge relation at this station is affected by backwater. Bankful stage occurs at about 22 feet.

EXTREMES oF DISCHARGE. Maximum stage recorded during years ending Septem* 

ber 30,1919 and 1920, 25.25 feet (creet) at 7.30 p. m. September 26,1919 (discharge, 

10,200 second-feet); minimum stage, 0.45 foot at 7 p. m. September 17, 1919 

(discharge, 86 second-feet).

1897-1903: Maximum stage recorded, 33.8 feet, June 3, 1903 (discharge, 10,600 

second-feet); minimum stage recorded, 3.7 feet in July and August, 1901 (discharge, 7 second-feet).

ICE. Stage-discharge relation affected by ice. Maximum ice thickness recorded 

during winter 1919-20, 3£ inches, December 9, 1919.

REGULATION. Blow noticeably affected by regulation of mill and power dams upstream, the nearest dam being near Bennington.

ACCURACY. $tage-discharge relation fairly permanent. Rating curves used as follows: May 15 to June 5, and June 12 to October 1, 1919, April 14 to July 30, and 

September 2-30,1920, fairly well defined below 8,000 second-feet; June 6-11,1919, 

well defined; October 2,1919, to April 13,1920, and July 31 to September 1,1920, 

curves poorly defined. Gage read to quarter-tenths twice daily during openwater periods, once daily to water surface, except as noted, during winter period. 

Daily discharge ascertained by applying mean daily gage height to rating table except when stage-discharge relation was affected by ice. Mean discharge for these 

periods based on observer's notes and weather records and on comparison with 

records of other stations in Smoky Hill River basin.

Recordjs for medium and low stages, May to September, 1919, April to July, and 

September, good; October, 1919, to March, 1920 {open water only), August, 1920, 

fair. Records for high stages, fair.. Records when stage-discharge relation was 

affected by ice, roughly approximate.

The accuracy of the discharge measurements made during the high stages of 

June and September, 1919, was impaired by the interference of the wooded banks 

with velocity of flow.

GAGE. Chain gage bolted to handrail of highway bridge. Three vertical high-water 

staff gages established as follows: Section No. 1, graduated from 14.0 to 19.0 feet, 

fastened to cottonwood tree on left bank, 170 feet north and 100 feet west of chain 

gage; section No. 2, 17.0 to 22.0 feet, fastened to cottonwood tree near road on 

right bank, 400 feet south and 50 feet westof chain gage; section No. 3,22.0 to 27.0 

feet, fastened to elm tree on right bank, 470 feet south and 150 feet east of chain 

gage. Gage read by Dan W. Fisk.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand and silt, control shifting. Stream 

confined to a small channel with fairly high banks, lined with trees and undergrowth. Bankful stage about 13 feet. During high stages, left bank is overflowed first, then the right bank, and highway bridge is inaccessible. The channel 

at high stages is obstructed by trees and undergrowth, making it impossible to 

obtain accurate and reliable hydrometric data except for low and medium stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during period of records, 22.5 

feet (crest) at 5 p. m. September 18, 1919 (discharge, 15,500 second-feet, based 

on extension of rating curve); minimum discharge, 3 second-feet, July 25,1920. 

High water in June, 1915, according to Mr. Dan W. Fisk of Kirwin, was about 2 

feet above handrail of newly completed highway bridge; corresponds to stag© 

of 27 feet (discharge, not determined).

ICE. Stage-discharge relation affected by ice. Maximum ice thickness during 

winter 1919-20, 4 inches, December 13-15, 1919.
KANSAS BT7EB BASIN. 387:

. Flow is affected by regulation of mill dam half a mile upstream. 

ACCURACY. Stage-discharge relation not permanent. Eating curve used August 

30 to October 9, 1919, fairly well defined below 6,000 second-feet and extended 

above that point; curves used October 10,1919, to August 5,1920, August 6-29, 

and August 30 to September 30, 1920uall poorly defined. Gage read to quartertenths twice daily during open-water periods and once daily to water surface 

during ice periods. Daily discharge ascertained by applying mean daily gage 

height to rating table except when stage-discharge relation was affected by ice. 

Mean discharge for this period based on observer's notes and weather record. 

Open-water records September, 1919, to February, 1920, fair; March to June, 

1920, good, July to September, 1920, fair. Records for period when stagedischarge relation was affected by ice, roughly approximate.

The high water of September 18, 1918, was occasioned by a rain of from 3 to 7 

inches over most of the drainage basin west of Kirwin. The observer's record is 

as follows:

a Falling stage. 6 Crest.

Observer stated the rise appeared to have a double crest, one caused by discharge 

from Boinr Creek and the other from the North Fork. First crest, stage .of about 

20 feet, occurred September 18 before 8 a. m. when observation was made. Stage 

fell to about 17 feet during the morning and again rose to crest height of 22.5 

feet at 3 p. m. The observer stated that the double crest usually occurred 

during high water, the first usually from Bow Creek.

of Hull, Marshall County. Elk Creek enters from east 4 miles upstream. Deer 

and Horseshoe creeks enter from west 2 and 3 miles respectively downstream.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. August 24, 1919, to September 30, 1920.

GAGE. Slightly inclined staff gage, reading from 2.0 to 26.1 feet, fastened to masonry 

pier on right bank. A high-water staff gage, reading from 26.0 to 32.0 feet, is 

spiked to elm tree 75 feet west of gage, 40 feet north of the highway. Gage read by 

Janies Pribyl.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Bed is gravel, control fairly permanent between high stages. 

Riffle about half a mile downstream forms the control for low and medium stages. 

Channel is straight in the vicinity of gage, with fairly high,, wooded banks. Bankful stage, about 22 feet. One channel at all stages except for flood stages, when

' left bank is overflowed considerably. Station is above backwater influence from 

dam at Marysville, about 7 miles downstream.

EXTREMES OP DISCHARGE. Maximum stage recorded during period of records, 16.4 

feet at 6.15 p. m. September 28,1919 (discharge, 11,300 second-feet from extension 

of rating curve); minimum discharge, about 85 second-feet September 27, 1920, 

from extension of rating curve. High-water mark, May, 1903, spike driven 

horizontally into elm tree on north side of road on right bank near high-water 

staff gage, referenced by observer, corresponds to a stage of 31.7 feet (discharge, 

not determined).

ICE. Stage-discharge relation affected by ice. Maximum ice thickness recordedduring winter 1919-20, 4J inches, December 2, 1919.

REGULATION. Flow.affected by regulation of power plants upstream, the nearest 

being at Oketo, about 5 miles upstream.

ACCURACY. Stage-discharge relation changed materially after June 27,1920. Rating 

curve used August 23,1919, to June 27,1920, fairly well defined between 200 and 

400 second-feet; curve used June 28 to September 30,1920, well denned between 

200 and 600 second-feet; curves extended above these limits to cover high stages. 

Gage read to half-tenths twice daily during open-water periods and once daily to 

water surface from December, 1919, to March, 1920. Daily discharge ascertained by applying mean daily gage height to rating table except when stagedischarge relation was affected by ice or backwater. Mean discharge for these 

periods based on observer's notes and weather records and on comparison with 

records on Big Blue River at Randolph. Discharge February 6-17, 1920, when 

stage-discharge was affected by backwater from ice gorge, based on low-water comparison with flow at Randolph. Open-water records September, 1919, to June, 

1920, fair; August, 1919, and July to September, 1920, good. Winter records 

roughly, approximate.

downstream end for use during extreme high stages. On August 22, 1919, a 

second high-water gage, graduated from 29.0 to 33.5 feet, was painted on vertical 

face of concrete support formerly used for oil tank, «a right bank, 500 feet west 

of chain gage.

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

wading.

CHANNEL AND CONTROL. Sand and gravel, control fairly permanent between highwater periods. Both banks are fairly high but subject to overflow at extreme 

stages. Bankful stage about 20 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during years ending September 30, 1919 and 1920, 20.95 feet at 10.30 a. m. June 11, 1919 (discharge, 22,300 

second^feet); minimum stage recorded, 2.2 feet at 7.40 p. m. September 15, 1919 

(discharge, 280 second-feet).

1918*1920: Maximum and minimum stages recorded, same as given above. 

1897-1912: Maximum stages recorded, 31.7 feet May 31, 1903, and 30.95 feet 

June 7, 1908 (discharge, not determined), (From data furnished by Mr. John 

Nord, of Randolph, reduced to datum of U. S. Geological Survey gage by levels 

of August 21 and 22, 1919. See table given below.) -

ICE. Stage-discharge relation affected by ice. Maximum ice thickness recorded 

during winter 1918-19, 6 inches, January 2 to 12, 1919; for winter 1919-20, 10 

inches, December 16-25, 1919.

REGULATION. Flow is affected by regulation of power plant at Blue Rapids.

Known locally as "Blue River.'
394 SURFACE WATEK SUPPLY, 1919-1920, PAET VI.

ACCURACY. Stage-discharge relation changed considerably during the high water of 

April, 1919. Before and since then, it has been fairly permanent. Bating curve 

used October 1, 1918, to April 10, 1919, fairly well denned; curve used April 11, 

1919, to September 30, 1920, well defined between 400 and 6,000 second-feet, 

poorly defined above this limit. Gage read to quarter^tenths twice daily. Daily 

discharge ascertained by applying mean daily gage height to rating table, except 

when stage-discharge relation was affected by ice. Mean discharge for these 

periods based on observer's notes and weather records and by comparison with 

records for other stations in the Kansas River valley. Records for open-water 

periods, October, 1918, to March, 1919, May, July, August, October, 1919, to 

September,' 1920, good; April, June, and September, 1919, fair; winter records 

subject to error. ".'. '..."". 

Data on high-water stages of Big Blue River at Randolph, Kans., during 1897 to

1912, have been^furnished by Mr. John Nord, of Randolph, who referred his readings

.to two reference marks as follows:

Reference mark No. 1: Cross on top of tie, Union Pacific Railroad bridge one-fourth

mile north of Randolph; elevation, 25 feet, 2 inches above his assumed datum (28.76

feet, U. S. Geological Survey gage datum). 

Reference mark No. 2: Horizontal cut in limestone wall of stone house west of

Union Pacific Railroad and south of Union Pacific Railroad bridge; elevation 38

feet 1 inch above his assumed datum (41.66 feet, U. S. Geological Survey gage datum). 

Mr. Nord's readings have been reduced to datum of U. S. Geological Survey gage

at Randolph by levels of August 21 and 22, 1919.

GRAND RIVER BASIN. 

THOMPSON RIVER AT DAV1S CITY, IOWA.

LOCATION. In sec. 35, T. 68 N., E. 26 W., at highway bridge in Davis City, Decatur 

County, 22 miles below mouth of Long Creek.

DRAINAGE AREA. 660 square miles. (Measured by engineers of the Iowa Highway 

Commission from U. S. post-route map.)

EECORDS AVAILABLE. May 14,1918, to September 30, 1920.

GAGE. Chain gage attached to downstream handrail of bridge; read by W. L. Severe.

DISCHARGE MEASUREMENTS. Low-water measurements made by wading about 1,000 

feet downstream from gage; medium stages measured from highway bridge; 

high stages measured from Chicago, Burlington & Quincy Railroad bridge 500 

feet downstream. v

CHANNEL AND CONTROL. Left bank is overflowed during floods. Low-water, control is the rock-nil dam at Chicago, Burlington & Quincy pumping station 300 

feet below gage. The remains of an old grist-mill dam 100 feet farther downstream 

formed the control at medium stages until it was carried out by heavy ice February 9,1920. The channel has a gravel bottom, the banks are well protected with 

a heavy growth of willows, and the control section is fairly permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30,1919,18.52 feet at 6.15 p. m. June 4 (discharge, 12,500 second-feet); minimum 

discharge, about 1 second-foot October 15 and 16.

Maximum stage recorded during the year ending September 30,1920,15.20 feet, 

at 6 p. m. March 24 (discharge, 6,570 second-feet); minimum discharge somewhat less than 10 second-feet in January.
398 SURFACE WATER SUPPLY, 1919-1920, PART VI.

1918-1920: Maximum stage recorded, 18.52 feet March 24, 1919 (discharge, 

12,500 second-feet); minimum discharge, about 1 second-foot, September 18-24, 

27-29, October 15 and 16, 1918. A stage of 22.8 feet referred to present gage was 

reached on August 8, 1885, according to distinct high-water mark.

ICE. Stage-discharge relation affected by ice.

ACCUEACY. Stage-discharge relation probably permanent for high stages; subject to 

change for low stages owing to changes in rock-fill dam, which constitutes the lowwater control. Gage read once daily to hundredths and twice daily during periods of rapidly changing stage. Daily discharge ascertained by applying daily 

gage height to rating table, except during winter when stage-discharge relation 

was affected by ice and the discharge was estimated by observer's notes, Weather 

- records, and comparison with records of flow at other stations. Open-water 

records good; winter records roughly approximate.

OS AGE (MABAIS DES CYGNES) RIVER BASIN. 

OSAGE RIVER HEAR OTTAWA, KANS.'

LOCATION. In NW. i sec. 6, T. 17 S., B. 20 E., at highway bridge on East Seventh 

Street, 1J miles southeast of Ottawa, Franklin County. Skunk Creek enters from 

west three-fourths mile upstream; Bock Creek enters from west 1 mile downstream; 

an old dam west of Main Street highway bridge is If miles upstream; Eightmile 

Creek enters from north 2f miles upstream; and waterworks dam of city of Ottawa 

is 3| miles upstream. '

DRAINAGE AREA. Not measured.

BECORDS AVAILABLE. October 27, 1918, to September 30, 1920. August 26,1902, 

to October 31,1905, records were obtained at Main Street Bridge at Ottawa.

GAGE. Stevens water-stage recorder on left bank, 100 feet upstream from highway 

bridge, inspected by G. C. Fitch (until February 3, 1920), Charles Lewis (February 20 to.September 3, 1920), and J. M. Lewis (since September 11, 1920). An 

auxiliary staff gage, in several sections, was installed May 10-12, 1&20, ttieeeighths mile upstream from the recording gage at a known difference in datum as 

ascertained by levels. Gage used by engineers of U. S. Geological Survey to obtain slope data in connection with current-meter measurements of discharge.

i Officially called " Osage River" in accordance with decision of United States Geographic Board, dated 

August 10,1897. The name "Marais des Cygnes River" was adopted by the Kansas State legislature df 

1919 (Session laws of 1919, eh. 322, p. 449).
OSAGE (MABAIS DBS OYGNES) BIVEE BASES". 401

DISCHARGE MEASUREMENTS. Made from downstream side of highway bridge or bywading.

CHANNEL AND CONTROL. Stream bed composed of shale; permanent. One channel 

except at extreme high stages when river overflows both banks. Channel is 

straight for a considerable distance upstream and downstream from the gage with 

steep, heavily wooded banks that form obstructions to free flow at high stages. 

The banks in the immediate vicinity of the gage have been cleared by property 

owners since the establishment of the station in order to improve measuring conditions at high stages. Bankful stage about 27 feet. The stream is subject to 

rapid variation in stage owing to heavy rains west of Ottawa. Point of zero flow, 

about gage height 1.15 feet, determined from measurements made July 31,1919, 

and March 20, 1920, and from inspection of rating curve.

EXTREMES OP DISCHARGE. Maximum stage during years ending September 80,1919 

and 1920, 25.9 feet at 2 a. m. September 14, 1920 (discharge, 11,600 second-feet); 

no flow June 27 and 28,1920.

During the flood of July, 1909, according to statements made by persons living 

in the vicinity of East Seventh Street bridge to engineers of the TJ. S. Geological 

Survey when the water-stage recorder installation was under construction during 

October, 1918, the river rose to a foot above the handrail, which is at gage height 

36.9 feet, making the highest known stage~approximately "38 f^et (discharge, not 

determined); the entire valley was flooded.

ICE. Stage-discharge relation affected by ice. Maximum ice thickness recorded, 

during winter 1918-19, 5 inches, January 3,1919; during winter 1919-20, 9 inches, 

December 19,1919 (practically frozen to bottom of channel as stream was at low 

stage).

REGULATION. Low-water flow is regulated by dams upstream (see "Diversions").

LIVERSIONS. The natural low-water- flow of the river is stored at the waterworks 

dam about 3£ miles upstream for water supply for city of Ottawa. A low temporary dam at Sheldon's Bridge, 4 miles west of Ottawa, held an auxiliary supply 

during the summer of 1918, when an acute water shortage was experienced. The 

drought in this river basin was not broken until the first part of November, 1918, 

after the gaging station was established. A new permanent storage dam 3$ miles 

upstream from the city's present dam is now under construction which is designed 

to increase, the available storage for Ottawa in the event of future droughts.

ACCURACY. Stage-discharge relation permanent; rating curve well defined. Currentmeter measurements made during periods of rapidly fluctuating stage were corrected to constant stage by method developed by the U. S. Geological Survey 

for correcting river discharge for changing stage.1 Determinations of slope were 

obtained September 13-16, 1920, by means of the auxiliary gage three-eighths 

mile upstream. Water-stage recorder checked weekly or oftener by observer's 

readings of outside and inside staff gages to hundredths. Operation of waterstage recorder was satisfactory except April 17, May 13, 14, 19, 1919, and short 

periods during April, May, August, and September, 1920, when clock troubles 

occurred. Mean daily gage height determined either from inspection of graph 

from water-stage recorder or by averaging the hourly gage heights when the fluctuations in stage were rapid. Gage-height record to open water surface during 

the ice periods. During January, 1919, ice went out with a gradual thaw. During 

the greater part of December, 1919, and January, 1920, the shallow channel was 

practically frozen solid; ice went out gradually the later part of January, 1920. 

Gage heights from water-stage recorder for this period omitted. Daily discharge 

ascertained by applying mean daily gage height to rating table, except when

402 SURFACE WATER SUPPLY, 1919-1920, PART VI.

stage-discharge relation was affected by ice or as noted for periods of rapidly 

fluctuating stage. Mean discharge for ice periods based on observer's notes, 

weather records, and inspection of water-stage recorder graph. Mean discharge 

for days when stage changed rapidly obtained by averaging hourly discharge 

corresponding to hourly gage heights. Discharge for periods when water-stage 

recorder was not in operation based on close inspection of fragments of graph and 

rainfall records for Ottawa and Quenemo. Open-water records for medium stages 

generally excellent; for extreme low and high stages, good. Winter records and 

estimated periods, roughly approximate.
