SURFACE WATER SUPPLY OF MISSOURI RIVER

BASIN, 1927

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, 1927.

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 West. Since the fiscal year ending June 

30, 1895, successive appropriation bills passed by Congress have 

carried the following items:

For gaging the streams and determining the water supply of the United 

States, and for the investigation of underground currents and artesian wells, 

and for the preparation of reports upon the best methods of utilizing the water 

resources.

In the execution of the work many private and State organizations 

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

made in connection with the description of each station affected; 

cooperation of the second kind is acknowledged on page 10.

Measurements of stream flow have been made at about 5,330 

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

the Hawaiian Islands. In July, 1927, 1,750 gaging stations were 

being maintained by the Geological Survey and *the cooperating

2 SURFACE WATER SUPPLY, 1927, PART VI

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

be defined as follows:

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

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

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

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

unit from which others are computed.

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

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

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

regards time and area.

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

if all the water flowing from it in a given period were uniformly distributed on the surface. It is used for comparing run-off with rainfall, which is usually expressed in depth in inches.

An "acre-foot," equivalent to 43,560 cubic feet, is the quantity 

required to cover an acre to the depth of 1 foot. The term is commonly used in connection with storage for irrigation.

The following terms not in common use are here defined:

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

of gage height to discharge."

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

stream below the gage which determine the stage-discharge relation 

at the gage. It should be noted that the control may not be the 

same section or sections at all stages.

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

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

control.
SURFACE WATER SUPPLY, 1927, PART VI 3 

EXPLANATION OF DATA

The data presented in this report cover the year beginning October 

1, 1926, and ending September 30, 1927. At the beginning of January in most parts of the United States much of the precipitation in 

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

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

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

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

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

precipitation within that year.

The base data collected at gaging stations consist of records of 

stage, measurements of discharge, and general information used to 

supplement the gage heights and discharge measurements in deterFIGTJBE 1. Typical gaging station

mining the daily flow. The records of stage are obtained either 

from direct readings on a staff or chain gage or from a water-stage 

recorder that gives a continuous record of the fluctuations. Measurements of discharge are made with a current meter by the general 

methods outlined in standard textbooks on the measurement of river 

discharge. A typical gaging station, equipped with water-stage 

recorder and measuring cable and car, is shown in Figure 1.

From the discharge measurements rating tables are prepared that 

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

heights to these rating tables gives the daily discharge from which 

the monthly and yearly mean discharge is determined.

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

by this report comprise a description of the station, a table giving
4 SURFACE WATER SUPPLY, 1927, PART VI

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 condition that may affect the permanence of the stage-discharge relation, 

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

for log driving, shifting of control, and the cause and effect of backwater. It gives also information as to diversions that decrease the 

flow at the gage, artificial regulation, maximum and minimum 

recorded stages, and the accuracy of the records.

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

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

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

fluctuation the discharge obtained from the rating table and the 

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

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

the mean daily discharge may be obtained by averaging discharge at 

regular intervals during the day or by use of the discharge integrator, an instrument operating on the principle of the planimeter and 

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

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

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

highest.. As the gage height is the mean for the day it does not 

indicate correctly the stage when the water surface was at crest 

height and the corresponding discharge was consequently larger than 

given in the maximum column. Likewise, in the column headed 

"Minimum" the quantity given is the mean flow for the day when 

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

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

average flow are based computations recorded in the remaining 

columns, which are defined on page 2.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS.

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

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

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

records.

A paragraph in the description of the station gives information 

regarding the (1) permanence of the stage-discharge relation, (2) precision with which the discharge rating curve is defined, (3) refinement
PUBLICATIONS 5

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

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

discharge.

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. 

Those notes are very general and are based on the plotting of the 

individual measurements with reference to the mean rating curve.

The monthly means for any station may represent with high accuracy the quantity of water flowing past the gage, but the figures 

showing discharge per square mile and depth in inches may be subject 

to gross errors caused by the inclusion of large noncontributing 

districts in the measured drainage area, by lack of information concerning water diverted for irrigation or other use, or by inability to 

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

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

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

The computations are also omitted for stations on streams draining 

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

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

published by the Geological Survey in earlier reports should be used 

with caution because of possible inherent but unknown sources of error.

Many gaging stations on streams in the irrigated areas of the 

United States are situated above most of the diversions from those 

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

available for further development, as prior appropriations below the 

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

prior appropriations a paragraph on diversions is presented in each 

station description. The figures given can not be considered exact 

but represent the best information available.

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

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

estimates; the tables of daily discharge allow more detailed studies 

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

the observations in each succeeding year may be expected to throw 

new light on data previously published.

PUBLICATIONS

Investigation of water resources by the United States Geological 

Survey has consisted in large part of measurements of the volume 

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

but it has comprised also investigation of such closely allied subjects 

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

quality of waters. Most of the results of these investigations have
6 SURFACE WATER SUPPLY, 1927, PART VI

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

appeared in the bulletins, professional papers, monographs, and 

,annual reports.

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

with natural drainage features as indicated below.

JSTOTE. No data regarding stream flow are given in the Fifteenth and Seventeenth Annual Reports.

The records at most of the stations discussed in these reports 

extend over a series of years, and miscellaneous measurements at 

many points other than regular gaging stations have been made each 

year. An index of the reports containing records obtained prior to 

1904 has been published in Water-Supply Paper 119.

The following table gives, by years and drainage basins, the numbers of the papers on surface-water supply published from 1899 to 

1927. The data for any particular station will be found in the reports 

covering the years during which the station was maintained. For 

example, data for Machias River at Whitneyville, Me., 1903 to 1921, 

are published in Water-Supply Papers 97, 124, 165, 201, 241, 261, 

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

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

of miscellaneous measurements are published by drainage basins.

COOPERATION

In Montana, until March, 1927, part of the work has been carried 

on under cooperative agreement with the United States Bureau of 

Reclamation, the work being done by the Geological Survey and the 

expense borne by the Bureau of Reclamation. After March, 1927, 

the expense was borne by the Department of State. The legislature 

of Montana made an appropriation for stream-gaging work, which 

was expended 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 the 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 several 

Carey Act projects and irrigation districts in Montana. Financial 

assistance was also rendered by the Mineral Range Power Co.; the 

South Bench Irrigation District, Three Forks, Mont.; and the LibertyMontana Mines Co.

Officials of the Yellowstone National Park furnished observers for 

gaging stations hi the park and have paid for a part of the expense of 

the work.

In Wyoming the work was carried on in cooperation with the State 

through John A. Whiting, State engineer. Financial assistance was 

also rendered by the United States Bureau of Reclamation, the United 

States Indian Service, the Douglas Reservoirs Water Users' Association, and Mr. Fred Firnekas, water commissioner.

In Colorado the work was carried on in cooperation with the State 

engineer, Mr. M. C. Hinderlider. Financial assistance was also 

rendered by the city of Denver, the city of Loveland, the city engineer 

of Boulder, the Farmers Reservoir & Irrigation Co., and Mr. Barton 

M. Jones.

In South Dakota the work was carried on in cooperation with the 

United States Bureau of Reclamation.

In Kansas the work was done hi cooperation with the Kansas Water 

Commission, which was succeeded on February 11 by the Division of 

Water Resources, State Board of Agriculture, George S. Knapp, 

chief engineer.

The work in Missouri and at the station on the Missouri River at 

Leaven worth, Kans., was carried on hi cooperation with the Missouri 

Bureau of Geology and Mines, through H. A. Buehler, State geologist.
MISSOURI RIVER PROPER 11

Financial assistance was also rendered by the United States Weather 

Bureau, United States Army Engineers, Chicago Great Western 

Railroad, Missouri Hydro-Electric Power Co., Central Missouri 

Power & Water Co., and Springfield City Water Co.

DIVISION OF WORK

Data for stations hi the upper Missouri and Yellowstone River 

Basins in Montana were collected and prepared for publication under 

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

Tuttle, C. S. Heidel, and Mrs. G. Thompson.

Data for stations hi Yellowstone National Park were collected and 

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

engineer, assisted by Berkeley Johnson, F. M. Veatch, and Miss 

E. H. Haugse.

Data for stations hi Colorado and Wyoming were collected and 

prepared for publication under the direction of Robert Follansbee, 

district engineer, assisted by P. V. Hodges and Miss N. L. Esterly.

Data for stations hi Kansas were collected and prepared for publication by J. B. Spiegel, district engineer, assisted by R. H. Husted.

Data for stations hi Missouri and for the station on the Missouri 

River at Leavenworth, Kans., were collected and prepared for publication under the direction of H. C. Beckman, district engineer, 

assisted by V. L. Austin, A. L. Hill, and C. H. Jennings.

The records were reviewed and the manuscript assembled by

MISSOURI RIVEE BELOW HAUSEE LAKE DAM, NEAE HELENA, MONT.

LOCATION. In SW. % sec. 29, T. 12 N., R. 2 W., at Hauser Lake power plant, 

15 miles northeast of Helena, Lewis and Clark County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. December 27, 1922, to September 30, 1927.

EQUIPMENT. Stevens continuous water-stage recorder installed on operating 

platform of power plant and connected to a float in exciter tailrace. Elevation of zero of gage, 3,563.00 feet above mean sea level. Discharge measurements made from cable three-fourths mile below dam.

CHANNEL AND CONTROL. Channel composed of heavy boulders and gravel. 

Control is heavy gravel bar 1,200 feet below power house; not subject to 

shift.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 78.80 feet 

June 14, 15, and 18 (discharge, 33,300 second-feet); minimum, 65.55 feet 

at 3.40 p. m. February 20 (discharge, 570 second-feet).

1922-1927: Maximum stage recorded, that of June 14, 15, and 18, 1927; 

minimum, 65.40 feet at 7 p. m. September 14, 1924 (discharge, 500 secondfeet).

DIVERSIONS AND REGULATION. Numerous diversions from river and tributaries 

above gage and two pumping plants located on Hauser Lake. Operation 

of power plants above station controls low-water flow and partly regulates flow at higher stages. Storage in Hebgen Reservoir controls flow of 

Madison River.

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

ice. Rating curve well defined below 20,000 second-feet and fairly well 

defined above. One discharge measurement, at 33,200 second-feet, made 

during the year checks the curve. Operation of water-stage recorder 

satisfactory. Daily discharge ascertained by averaging discharge for 

intervals of a day and checked by discharge integrator. Records excellent.

COOPERATION. Complete records furnished by Montana Power Co. Data 

reduced to three significant figures for publication.

daily gage height to rating table or, for days of considerable fluctuation 

while recorder was in operation, by use of the discharge integrator, except 

for period of ice effect or of no record as indicated in footnote to table of 

daily discharge. Records good.

feet above St. Louis city datum and 713.53 feet above mean sea level. 

Discharge measurements made from downstream side of bridge.

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

bank high. Left bank is overflowed at stage of 52 feet. No well-defined 

control.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 49.3 feet 

May 17, 18, an,d June 29, 30 (discharge, 213,000 second-feet); minimum 

discharge, 9,200 second-feet December 21 and 22, when river was frozen.

1922-1927: Maximum discharge recorded, 241,000 second-feet July 7 and 

8, 1923; minimum, 3,450 second-feet (measured with current meter) December 22, 1924

The Army engineers report a maximum stage of 53.0 feet April 29 and 30, 

1881, and a low-water stage of 29.2 feet December 9 and 10, 1873, and 

January 6, 1874; these records corrected to datum of present gage.

DIVERSIONS AND REGULATION. None.

ACCURACY. Stage-discharge relation not permanent during year; seriously 

affected by ice during winter. Rating curve fairly well defined above 

15,000 second-feet by eight discharge measurements, three of which were 

made during the year. Gage re^id to tenths once daily. Daily discharge 

ascertained by shifting-control method until November 30 and by applying 

daily gage height to rating table after that date. Records fair except those 

for periods of ice effect, which are poor.

States Weather Bureau has obtained records of stage at Missouri, Kansas 

& Texas Railway bridge one-fourth mile upstream since 1873.

EQUIPMENT. Chain gage on bridge. Zero of gage is 562.71 feet above mean sea 

level. Discharge measurements made from downstream side of bridge.

CHANNEL AND CONTROL. Bed composed of sand and mud; shifting. Right 

bank high; left bank overflowed at stage of 24 feet. No well-defined control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 26.87 feet at 

9 a. m. April 23 (discharge, 381,000 second-feet); minimum discharge, 19,000 

second-feet December 21 and 22 when river was frozen.

1926-1927: Maximum stage recorded, that of April 23, 1927; minimum 

discharge, that of December 21 and 22, 1926.

On June 21, 1844, the river reached a stage of 35.9 feet, and on June 5, 

1903, a stage of 33.3 feet; stages determined from chiseled marks on stone 

monument near right end of bridge.

DIVERSIONS AND REGULATION. None.

ACCURACY. Stage-discharge relation not permanent during year; seriously 

affected by ice during winter. Rating curve fairly well defined above 25,000 

second-feet by 13 discharge measurements, 3 of which were made during the 

year. Gage read to hundredths once daily. Daily discharge ascertained by 

applying daily gage height to rating table December 5 to June 15; shifting-control method based upon two discharge measurements used remainder 

of year. Records fair except those for periods of ice effect, which are poor.

EQUIPMENT. Chain gage on bridge; installed July 17, 1927. Gage used prior 

to June 10, 1927, was Stevens continuous water-stage recorder in wooden 

shelter on left bank; lost during flood. Both gages set to same datum." 

Discharge measurements made from highway bridge or by wading.

CHANNEL AND CONTROL. Channel composed of heavy gravel and sand between 

large boulders. Control is riffle of same material 400 feet below gage; 

subject to change owing to movement of sand and gravel between boulders.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, determined

by levels from high-water mark, 14.0 feet June 10 (discharge not determined);

minimum, 1.55 feet at 4 p. m. November 17 (discharge, 326 second-feet).

1924-1927: Maximum stage recorded, that of June 10, 1927; minimum,

1.02 feet at 11.30 p. m. September 3, 1924 (discharge, 228 second-feet).

DIVERSIONS AND REGULATION. Several small diversions for irrigation above 

station. Operation of power plant above station causes some fluctuation 

in stage.

ACCURACY. Stage-discharge relation changed by flood of June 10. Two 

rating curves used during year; one applicable prior to November 23 is 

well defined between 300 and 5,000 second-feet by 13 discharge measurements 

well distributed along curve; the other, used since July 17, is well defined 

by five measurements between 750 and 8,000 second-feet. Five measurements, covering a range from 475 to 7,640 second-feet were made during 

the current year and check the curve closely. Operation of water-stage 

recorder not satisfactory. Chain gage read to hundredths or half-tenths 

once daily after July. 17. Daily discharge ascertained by applying daily 

or mean daily gage height to rating table. Records good but verjfragmentary.

MADISON RIVER BASIN

MADISON RIVER NEAR WEST YELLOWSTONE, MONT.

LOCATION. 250 feet upstream from old footbridge at ford on old Gallatin trail, 

just north of highway to West Yellowstone, and 4 miles east of West Yellowstone and west boundary of Yellowstone National Park. Gibbon and 

Firehole Rivers unite to form Madison River 9 miles upstream.

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

RECORDS AVAILABLE. June 16, 1913, to September 30, 1927.

EQUIPMENT. Friez water-stage recorder on left bank. Gage datum for recrrder 

raised 2.50 feet June 29,1926, but records were not based on present datum 

until October. 1, 1926. During winter periods, because of unfavorable 

conditions caused by severe ice and snow at recorder site, a vertical staff at 

different datum on left bank 500 feet below was used. Discharge measurements made from cable two-thirds mile below gage or by wading.

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

rough. One channel at all stages. Aquatic growth is present during greater 

part of year and at times causes backwater. Control practically permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 2.36 feet at 8 a. m. June 9 (discharge, 1,770 second-feet); 

minimum estimated discharge, 325 second-feet December 12-15.

1913-1927: Maximum stage recorded, 2.64 feet (old vertical staff) at 

6 p. m. June 10, 1917 (discharge, 1,950 second-feet); minimum, 1.1 feet 

(vertical staff) February 2, 1924 (discharge, 284 second-feet).

DIVERSIONS AND REGULATION. None.

ACCURACY. Stage-discharge relation changed within well-defined limits by moss 

growth during summer; affected slightly by ice for short periods in December 

and January. Rating curve for staff gage used December 11 to May 7 is 

well defined and was closely checked by discharge measurements in 1927; 

rating curves for recorder site used during remainder of the year are based 

on standard rating and six measurements ranging from 489 to 1,620 secondfeet made during June to September, 1927. Operation of water-stage 

recorder satisfactory October 1 to December 8 and May 14 to September 

30; during intervening period staff gage at lower site was read to hundredths about once a week. Daily discharge ascertained .by applying 

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

of daily discharge. For periods when water-stage recorder was operated, 

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

Records good October to December 8 and after June 10^ others fair.

SUN EIVEE AT FOET SHAW, MONT.

LOCATION. In SW. % sec. 1, T. 20 N., R. 2 W., at highway bridge at Fort Shaw,

Cascade County. 

DRAINAGE AREA. 1,475 square miles (measured by United States Bureau of

Reclamation). 

RECORDS AVAILABLE. May 16, 1912, to September 30, 1927. 'A station on

Sun River at Sun River, maintained July 31, 1905, to October 5, 1912, gave

results for practically the same drainage area. 

EQUIPMENT. Stevens continuous water-stage recorder in shelter on left bank

under highway bridge and chain gage on bridge. Discharge measurements

made from cable 500 feet below gage or by wading. 

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

occasionally. 

EXTRSMES OF DISCHARGE. Maximum stage recorded during year, 10.42 feet

at 6 p. m. June 9 (discharge, 10,400 second-feet); minimum, 3.91 feet at

11 a. m. April 21 (discharge, 219 second-feet).

1905-1927: Maximum stage recorded, 13.4 feet June 7, 1928 (discharge,

18,400 second-feet); minimum, 3.04 feet August 27, 1926 (discharge, 38

second-feet).
42 SURFACE WATER SUPPLY, 1927, PART VI

DIVERSIONS AND REGULATION. Willow Creek Reservoir has a capacity of 

16,640 acre-feet. There are adjudicated rights for diverting 248 secondfeet from Sun River direct and 664 second-feet from tributaries above 

this station. In addition there are the Fort Shaw and Pishkun Canals of 

the United States Bureau of Reclamation and a few small ditches constructed since the adjudication.

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

curve well defined between 35 and 400 second-feet and fairly well defined 

between 400 and 7,000 second-feet. Operation of water-stage recorder 

satisfactory except as indicated in footnote to table of daily discharge. 

Chain gage read to half-tenths at irregular intervals during periods when 

recorder was not operating. Five discharge measurements, covering a 

range, from 656 to 7,120 second-feet, were made during the current year. 

Daily discharge ascertained by applying mean daily gage height to rating 

table, using shifting-control method June 14 to August 21, except as noted 

in footnote to table of daily discharge. Records for medium and low stages 

good, others fair; winter records poor.

COOPERATION. United States Bureau of Reclamation furnished some gage 

readings.

MARIAS RIVER BASIN

MARIAS RIVER NEAR SHEIBY, MONT.

LOCATION. In sec. 20, T. 31 N., R. 2 W., at highway bridge 7 miles south of 

Shelby, Toole County.

DRAINAGE AREA. 2,610 square miles.

RECORDS AVAILABLE. April 4, 1902, to January 12, 1908; April 23, 1911, to. 

September 30 1922; March 26, 1923, to September 30, 1927.

EQUIPMENT. Stevens water-stage recorder on downstream side of pier on left, 

bank. Discharge measurements made from downstream side of highway 

bridge or by wading.

boundary, 30 miles north of Rudyard, Hill County, Mont., and 37 miles 

south of Many Berries, Alberta.

DRAINAGE AREA. 2,514 square miles (measured by engineers of Irrigation 

Branch, Department of the Interior, Canada).

RECORDS AVAILABLE. April 1, 1913, to September 30, 1927. From August 7, 

1909, to 1912, maintained by Irrigation Branch, Department of the Interior, 

Canada.

EQUIPMENT. Au water-stage recorder on left bank; installed October 13, 1926. 

Prior to that date a Stevens continuous water-stage recorder at same site 

was used. Elevation of zero of both gages, 2,698.92 feet above sea level. 

Discharge measurements made from cable or by wading.

CHANNEL AND CONTROL. A bar composed of heavy boulders, gravel, and sand 

makes*a decided riffle at medium and low stages; shifts frequently.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 10.16 feet at 

4.40 p. m. May 23 (discharge, roughly 12,000 second-feet); minimum, 0.58 

foot November 5 (discharge, 25.9 second-feet).

1909-1927: Maximum stage recorded, that of May 23, 1927; no flow 

August 3-17, 22, 23, 1914, February 1 to March 13, 1922,. and March 1-5, 

1923.

DIVERSIONS AND REGULATION. No diversions. Natural flow increased by 

approximately 53,200 acre-feet of water from St. Mary Canal during irrigation season of 1927.

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

observations discontinued during winter. Two standard rating curves used 

during year; the first, used during October, is well defined between 25 and 

750 second-feet; the other, used April 1 to September 30, is well defined 

between 20 and 2,000 second-feet, and extended above. Nineteen discharge 

measurements, covering a range from 26 to 2,440 second-feet, were made 

during the year. Operation of water-stage recorder fairly satisfactory. 

Daily discharge ascertained by applying mean daily gage height to rating 

table, using shifting-control method October 1-31, April 1 to May 10, June 9 

to July 5, July 14 to August 10, and September 10-30, except as noted in 

footnote to table of daily discharge. Records good below 2,000 second-feet 

and fair above.

YELLOWSTONE RIVER AT YELLOWSTONE LAEE OUTLET, YELLOWSTONE NATIONAL PARE

LOCATION. At Fishing Bridge, a quarter of a mile below outlet of Yellowstone

Lake and \% miles northeast of Lake Hotel.

DRAINAGE AREA. 1,010 square miles (measured on topographic maps). 

RECORDS AVAILABLE. December 3, 1922, to September 30, 1927, Gage-height

records only prior to October 1, 1925.
80 SURFACE WATER SUPPLY, 1927, PART VI

EQUIPMENT. Vertical staff near left bank attached to pile on upstream side of 

Fishing Bridge. Gage datum is 7,728.90 feet above mean sea level. Discharge measurements made from boat a short distance above gage.

CHANNEL AND CONTROL. Bed composed of gravel. Right bank subject to overflow above gage, but below gage the flow is well confined at all stages. A 

small island divides river into two channels for- a short distance below gage. 

Control is formed by a gravel and rock riffle below lower end of this island.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.3 feet June 

29, 30, and July 1 (discharge, 7,420 second-feet); minimum, 0.94 foot January 9 and 10 (discharge, 560 second-feet).

1922-1927: Maximum and minimum stages were recorded in 1927.

DIVERSIONS AND REGULATION. None.

ACCURACY. Stage-discharge relation permanent except for slight ice effect for 

short periods. Rating curve fairly well defined between 1,000 and 8,000 

second-feet; based on three discharge measurements made during 1928 at 

this station and by 23 measurements made during 1923 to 1927 at Canyon 

station, 13 miles below, after deducting estimated intervening inflow. Gage 

read to hundredths October 1 to June 8 and to half-tenths June 9 to September 30. After June 6 the gage was read daily; prior thereto, particularly 

during winter, when stages were fairly constant, there were periods when gage 

was not read regularly. Daily discharge determined by applying daily gage 

height to rating table except as noted in footnote to table of daily discharge. 

Records good except those for extremely high stages and for estimated 

periods, which .are fair.

COOPERATION. Gage-height record furnished by officials of Yellowstone Park.

NOTE. The gage-height record shows approximate stages in Yellowstone Lake, but owing to a small 

amount of fall between the main body of lake and gage, daily elevations derived from the gage below the 

outlet are slightly less than those obtained from the gage in Yellowstone Lake at the Lake Hotel. Gage 

heights for period July 10-20 were corrected on basis of graphic comparison with readings obtained at Lake 

Hotel, because original readings by observer were in error.

YELLOWSTONE RIVER NEAR CANYON HOTEL, YELLOWSTONE NATIONAL PARE

LOCATION. Half a mile upstream from Upper Falls and Canyon ranger station, 

1% miles south of Canyon Hotel, and 13 miles below outlet of Lake Yellowstone.

DRAINAGE AREA. 1,280 square miles (measured on topographic maps).
82 SURFACE WATER SUPPLY, 1927, PART VI

RECORDS AVAILABLE. June 21, 1913, to September 30, 1927.

EQUIPMENT. Stevens continuous water-stage recorder on left bank, 450 feet 

above Chittenden Bridge. Discharge measurements made from cable onefifth mile above gage.

CHANNEL AND CONTROL. Bed composed of gravel and boulders. One channel 

at all stages. Control formed by upper part of Upper Yellowstone Falls; 

permanent for long periods. /

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage 

recorder, 4.23 feet from 7 to 10 p. m. June 30 (discharge, 7,890 second-feet); 

minimum, 0.83 foot October 13 and 14 (discharge, 758 second-feet). Lower 

stage and discharge occurred during winter, when observations were discontinued,

1913-1927: Maximum stage recorded, 4.50 feet June 27, 1918 (discharge, 

8,550 second-feet); minimum, 0.72 foot September 6, 1919 (discharge, 

664 second-feet). Not actual minimum.

DIVERSIONS AND REGULATION. None.

ACCURACY. Stage-discharge relation permanent; observations discontinued during winter. Rating curve well defined between 1,000 and 8,000 secondfeet on basis of 17 discharge measurements made during 1925 to 1927, of 

which six measurements, ranging from 1,770 to 7,850 second-feet, were 

made during the year. Operation of water-stage recorder satisfactory 

except for two short periods. Daily discharge ascertained by applying to 

rating table mean daily gage height obtained by inspection of recorder graph, 

except as noted in footnote to table of daily discharge. Records excellent.

YELLOWSTONE RIVER BASIN 83

YELLOWSTONE RIVER AT CORWIN SPRINGS, MONT.

LOCATION. In NE. Y* sec. 30, T. 8 S., R. 8 E., at highway bridge in canyon at 

Corwin Springs, Park County, 8 miles north of Gardiner.

DRAINAGE AREA. 2,630 square miles.

RECORDS AVAILABLE. September 2, 1910, to September 30, 1927.

EQUIPMENT. Chain gage fastened to floor of highway bridge on downstream side 

near right bank. Discharge measurements made from downstream side of 

bridge.

CHANNEL AND CONTROL. Bed of stream composed of small rocks. Current 

swift at all stages; no definite control, but there has been no shift since station was established. Banks high and not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 10.0 feet at 

9 a. m. June 27 (discharge, 21,500 second-feet); minimum, 0.75 foot December 13 and 14 (discharge, 890 second-feet).

1910-1927: Maximum stage recorded, 11.5 feet June 14 and 15, 1918 

(discharge, from extension of rating curve, 26,500 second-feet); minimum 

discharge, estimated, 720 second-feet January 8-10, 1920.

DIVERSIONS AND REGULATION. No water diverted from Yellowstone River above 

station. Yellowstone Lake furnishes a natural but uncontrolled regulation.

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

by ice. Rating curve well defined between 1,000 and 18,300 second-feet; 

extended beyond these limits. No discharge measurements were made 

during the year. Gage read to hundredths once daily. Daily discharge 

ascertained by applying daily gage height to rating table except as indicated 

in footnote to table of daily discharge. Records good except those for estimated periods, which are fair.

YELLOWSTONE RIVER AT INTAKE, MONT.

LOCATION. In NW. % sec. 36, T. 18 N., R. 56 E., at Lower Yellowstone diversion 

dam at Intake, Dawson County, 18 miles below Glendive.

DRAINAGE AREA. 66,800 square miles (measured on base maps of Montana and 

Wyoming).

RECORDS AVAILABLE. January 1, 1911, to September 30, 1927. At Glendive, 

18 miles above, by War Department and Department of Agriculture, 1893 to 

1903, and by Geological Survey August 1, 1903, to December 31, 1910.

EQUIPMENT. Chain gage on left abutment of dam. Gage readings represent 

depth of water on crest of dam. 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 

timber-crib structure on pile foundation 700 feet long, crosses the stream at 

right angles to current, and raises low-water level about 4 feet; specially 

designed to resist the destructive effects of ice by approach on a slope of 3 to 

1; downstream face is ogee-shaped and protected by a heavy rock apron.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 9.4 feet July 

1 (discharge, 101,000 second-feet); minimum, 0.70 foot December 21 and 22 

(discharge, 3,010 second-feet).

1903-1927: Maximum stage recorded, 12.6 feet June 21, 1921 (discharge, 

159,000 second-feet); minimum, 0.2 foot December 6-8, 1922, and January 

6 and 7, 1923 (discharge, estimated because of ice, 1,200 second-feet).

DIVERSIONS AND REGULATION. The Lower Yellowstone Canal, which diverts 

water to irrigate 66,000 acres, heads at left abutment of dam. Of the several 

diversions from the main streams above station the United States Bureau of 

Reclamation Huntley project and the Billings Carey Act project are the 

largest. There are also numerous diversions from the tributaries. Yellowstone Lake and Shoshone Reservoir form the only important regulation and 

control only a small part of the flood flow.

ACCURACY. Stage-discharge relation probably permanent; slightly affected by 

ice. Rating curve well defined below 80,000 second-feet and fairly well 

above by fourteen discharge measurements made prior to 1927. No measurements made during the year. Gage read to half-tenths twice daily. Daily 

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

Records good.

TOWER CREEK AT TOWER FAILS, YELLOWSTONE RATIONAL FARE

LOCATION. A short distance above Tower Falls and bridge on highway leading 

to Camp Roosevelt, a quarter of a mile above junction of Tower Creek with 

Yellowstone River, and 2 miles southeast of Camp Roosevelt.

DRAINAGE AREA. 51 square miles (measured on topographic maps).

RECORDS AVAILABLE. September 2, 1922, to September 30, 1927.
86 SURFACE WATER SUPPLY, 1927, PART VI

EQUIPMENT. Vertical staff on right bank. Discharge measurements made 

from footbridge three-eighths mile above gage or by wading.

CHANNEL AND CONTROL. Bed composed of lava rock, boulders, and gravel. 

One channel at all stages. Control formed by rock riffle 30 feet below gage; 

well defined and fairly permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 6.1 feet June 

22, 25, and 26 (discharge, 583 second-feet); minimum discharge, 17 secondfeet March 26-31. Probably not actual minimum.

1922-1927: Maximum stage recorded, 6.16 feet May 30, 1925 (discharge, 

642 second-feet); minimum, 3.38 feet May 6, 1924 (discharge, 13 second-feet).

DIVERSIONS AND REGULATION. None.

ACCURACY. Stage-discharge relation changed June 9 and 10; not affected by ice 

because of springs and snow cover. Rating curve used October 1 to June 8 

is well defined between 25 and 100 second-feet by thirteen discharge measurements made in 1925 and 1926; curve used after June 10 is well defined 

between 35 and 450 second-feet by eight measurements ranging from 35 to 

443 second-feet made during the year. Gage read to hundredths about once 

daily June 11 to September 10; at other times less frequently. Daily 

discharge determined by applying daily gage height to rating table except 

as indicated in footnote to table of daily discharge. Records after June 10 

good; others fair.

LAMAR RIVER NEAR TOWER FAILS RANGER STATION, YELLOWSTONE NATIONAL PAKE

LOCATION. Half a mile north of Cooke City road, three-fourths mile above 

junction with Yellowstone River, and 2 miles northeast of Tower Falls 

ranger station.

DRAINAGE AREA. 640 square miles (measured on topographic maps).

RECORDS AVAILABLE. September 2, 1922, to September 30, 1927.

EQUIPMENT. Au continuous water-stage recorder on left bank. Gage datum 

lowered 1.00 foot on July 29, 1927. Discharge measurements made from 

cable 50 feet below gage or by wading.

CHANNEL AND CONTROL. Bed composed of lava rock, boulderg, gravel, and sand. 

One channel at all stages. Control is formed by gravel and boulder riffle 

200 feet below gage; well defined and practically permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from highwater marks on gago, 8.62 feet May 17 (discharge, 13,100 second-feet); 

minimum discharge^ estimated 125 second-feet December 12-15, during 

ex'tremely cold period. Probably not actual minimum.

1922-1927: Maximum stage recorded, that of May 17, 1927; minimum, 

 0.08 foot April 20, 1924 (discharge, 104 second-feet). Lower stage and 

discharge have occurred during periods of no record.

DIVERSIONS AND REGULATION. None.

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

winter. Owing to difference in gage readings at certain stages between the 

outside and inside staff gages, two rating curves were used; the first, referred 

to outside staff, used January 6 to April 30, May 1-15, 21-25, 28-31, and 

June 1-4, is well defined between 150 and 9,000 second-feet; the second, 

referred to inside staff, was used during remainder of year and is well defined between 150 and 11,000 second-feet, based on nine discharge measurements made during 1925 to 1927, of which four measurements ranging from 

558 to 10,200 second-feet were made during the year. Operation of waterstage recorder satisfactory October 1 to December 31 and after June 5; staff 

gage read at irregular intervals during intervening period. Daily discharge 

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

except as indicated in footnote to table of daily discharge. Records October 

1 to December 5 and June 6 to September 30 excellent; others fair except 

those for estimated periods, which are poor.

GARDINER RIVER AT MAMMOTH HOTEL, YELLOWSTONE NATIONAL PARE

LOCATION. A quarter of a mile downstream from footbridge on trail crossing 

leading to Mount Everts, three-eighths mile below inflow from Mammoth 

Hot Springs, nine-tenths mile northeast of Mammoth Hotel, and 5 miles 

above junction with Yellowstone River.

DBAINAGE AREA. 201 square miles (measured on topographic map).
YELLOWSTONE RIVER BASIN 89

RECORDS AVAILABLE. September 3, 1922, to September 30, 1927.

EQUIPMENT. Au water-stage recorder on left bank; installed July 30, 1927. 

From June 10 to July 29, 1927, a vertical staff gage at present site and datum 

was used. Prior to June 10, 1927, gage was a vertical staff a quarter of a 

mile upstream at different datum from present gage. Discharge measurements made from footbridge a quarter of a mile upstream from present gage 

or by wading.

CHANNEL AND CONTROL. Bed composed of gravel and boulders. One channel 

at all stages. Control formed by stretch of the stream bed below gage.

EXTREMES OF DISCHARGE. Maximum discharge recorded during year, 1,540 

second-feet during early morning of June 12; minimum discharge, 62 

second-feet November 17 and April 11.

1922-1927: Maximum and minimum discharges recorded, same as for 1927. 

Lower flow may have occurred during extremely cold period December 17-26, 

1924, when gage was not read.

DlVERSJONS AND REGULATION. None.

ACCURACY. Stage-discharge relation changed May 1 and 17, below old gage 

site; permanent after June 9, at new gage site; not affected by ice, owing 

to warm springs above. Rating curves for old gage not well defined; rating 

curve for new gage, used after June 10, well denned between 100 and 1,800 

second-feet. Seven discharge measurements, covering a range from 162 to 

1,470 second-feet, were made during the year. Staff gage read to hundredths 

once daily October 1 to July 29, except during winter, when readings were 

not made regularly; thereafter operation of water-stage recorder was satisfactory. Daily discharge ascertained by applying daily or mean daily gage 

height to rating table, except as noted in footnote to table of daily discharge. 

Records fair prior to July 29; excellent thereafter.

LOCATION. In sec. 36, T. 43 N., R. 95 W., at highway bridge between Thermopolis and Hot Springs, Hot Springs County. Nearest tributary, Thermopolis Hot Springs, discharges 9 second-feet into Big Horn River a short 

distance downstream.

DRAINAGE AREA. 8,080 square miles (measured on base map of Wyoming).

R.ECORDS AVAILABLE. May 28, 1900, to December 31, 1905; June 30, 1910, 

to September 30, 1927.

EQUIPMENT. Chain gage on downstream handrail of concrete bridge. Discharge measurements made from 2-span highway bridge a third of a mile 

upstream.

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

Control for low and medium stages a short distance below; shifts at intervals. High-water control is formed by vertical walls of canyon entrance 

half a mile downstream. Banks high and not subject to overflow except 

during extreme flood stage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 9.7 feet at 

5.30 p. m. June 30 (discharge, 14,800 second-feet); minimum, 0.26 foot 

December 16 and 17 (discharge, 415 second-feet).

from Big Horn River above station. For diversions from Wind River see 

Wind River at Riverton. No regulation.

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

Rating curve well defined by 16 measurements between 600 and 12,000 

second-feet; extended beyond those limits. Nine measurements were 

made during the year. Gage read to quarter-tenths twice daily. Daily 

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

using shifting-control method August 25 to September 9. Records good.

at small rapids just below gage; slightly shifting at long intervals. Banks 

not subject to overflow.

EXTREMES OF DISCHAKGE. Maximum stage during year, from water-stage 

recorder, 7.23 feet at 8 a. m. June 29 (discharge, 3,340 second-feet); minimum discharge during winter.

1918-1927: Maximum discharge recorded, 3,990 second-feet at 2 p. m. 

June 16, 1918; minimum discharge, from current-meter measurement, 17.8 

second-feet February 1, 1919.

DIVERSIONS AND REGULATION.: Two ditches divert water above station for 

irrigation of 200 acres. Flow naturally regulated by Bull Lake, which has 

an area of 4 square miles.

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

curve used October 1 to February 28 is well defined by eight discharge 

measurements; curve used March 7 to September 30 is defined by two 

discharge measurements between 50 and 2,000 second-feet and extended 

beyond those limits. Operation of water-stage recorder satisfactory during 

open water; staff gage read once a week December 1 to March 31. Daily 

discharge ascertained by applying to rating table mean daily gage height 

obtained by inspection of recorder graph, except as indicated in footnote to 

table of daily discharge. Records good except those for estimated periods, 

which are fair.

junction with North Fork at Fort Washakie, Fremont County, on Wind 

River Diminished Reservation.

DRAINAGE AREA. 134 square miles (measured on base map of Wyoming).
YELLOWSTONE RIVER BASIN 105

RECORDS AVAILABLE. May 11, 1921, to September 30, 1927.

EQUIPMENT. Gurley 7-day water-stage recorder on right bank 500 feet above 

head gate of Ray ditch. Discharge measurements made from cable 300 

feet below gage.

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

Control poorly defined. Banks not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage 

recorder, 5.5 feet at noon June 28 (discharge, 1,670 second-feet); minimum 

stage during winter.

1921-1927: Maximum stage recorded, 7.59 feet at 2 p. m. July 9, 1926 

(discharge, estimated from slope and cross section, 5,220 second-feet); 

minimum discharge, 14 second-feet February 22, 1921.

DIVERSIONS AND REGULATION. A few small ditches divert water above station. 

Diurnal fluctuation during spring from alternate melting and freezing of 

mountain snow.

ACCURACY. Stage-discharge relation practically permanent; affected by ice, 

records discontinued during winter. Rating curve fairly well defined 

between 50 and 800 second-feet by four discharge measurements made 

during current year; extended beyond those limits. Operation of waterstage recorder fairly satisfactory. Daily discharge ascertained by applying 

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

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

good.

three-quarters of a mile downstream.

DRAINAGE AREA. 164 square miles (measured on topographic map).

RECORDS AVAILABLE. August 8, 1920, to January 10, 1927, when station was 

discontinued.

EQUIPMENT. Gurley water-stage recorder 1,000 feet upstream from bridge 

at State Fish Hatchery. Discharge measurements made from cable 300 

feet below gage or by wading.

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

25 feet downstream; shifts occasionally. Banks not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 1.69 feet 

at 5 p. m. October 27 (discharge, 117 second-feet); minimum stage probably 

occurred during winter.

1920-1927: Maximum stage recorded, 7.2 feet at 1 a. m. July 24, 1923 

(discharge, 4,960 second-feet); minimum, 0.29 foot from 10 a. m. to 1 p. m. 

February 17, 1921 (discharge, 14 second-feet).

.DIVERSIONS AND REGULATION. Station is above all diversions except that for 

Rhinehart ditch, which diverts water for irrigation of 12 acres. Below 

station are adjudicated diversions for irrigation of 4,700 acres. 

.ACCURACY. Stage-discharge relation permanent during year; affected by ice. 

Rating curve fairly well defined by nine discharge measurements, one of 

which was made August 8,1926, at a discharge of 115 second-feet, and another 

January 10, 1927, at a discharge of 33 second-feet. Operation of water-stage 

recorder fairly satisfactory October 1 to November 14; .gage read, once a 

week November 15 to January 10. Daily discharge ascertained by applying 

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

graph October 1 to November 14. Records good except during estimated 

periods, for which they are poor.

TONGUE RIVER NEAR DAYTON, WYO.

LOCATION. In SE. % sec. 2, T. 56 N., R. 87 W., above Highline ditch, at mouth 

of canyon, 3% miles southwest of Dayton, Sheridan County. Nearest 

tributary, Amsden Creek, enters \% miles downstream.

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

RECORDS AVAILABLE. October 24, 1911, to May 25, 1912 (fragmentary gageheight record); November 18, 1918, to September 30, 1927. From May 1 

to October 31, 1903, at Dayton.

EQUIPMENT. Stevens 7-day water-stage recorder on left bank, 1,000 feet below 

head gate of Highline Canal. Discharge measurements made from cable 100 

feet downstream or by wading.

 CHANNEL AND CONTROL. Bed composed of boulders and coarse gravel, well 

compacted. Control 200 feet downstream; shifts slightly at long intervals.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage 

recorder, 5.07 feet at 8.30 p. m. May 17 (discharge, 2,030 second-feet); 

minimum, 1.39 feet December 14 (discharge, 35 second-feet).

1918-1927-: Maximum stage recorded, 5.57 feet at 1 a. m. June 15, 1924 

(discharge, 2,460 second-feet); minimum, 1.00 foot at 9 p. m. November 29, 

1919 (discharge, 15 second-feet).

DIVERSIONS AND REGULATION. Only diversion above station is Highline Canal, 

which diverts about 3,500 acre-feet annually. Alternate melting and freezing of mountain snow during spring cause diurnal fluctuation.

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

Rating curve well defined between 60 and 1,300 second-feet and checked by 

a measurement made May 24 at a discharge of 637 second-feet. Operation 

of water-stage recorder satisfactory. Daily discharge ascertained by applying to rating table mean daily gage height obtained by inspection of recorder 

graph. Records excellent. "

CLEAR CREEK NEAR BUFFALO, WYO.

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

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

RECORDS AVAILABLE. June 16, 1917, to October 31, 1927, when station was discontinued. From June 1 to September 30, 1894, and from May 2, 1896, to 

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

Flow at two points comparable.

EQUIPMENT. Chain gage on left bank 300 feet above power house. 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; shifts slightly at intervals. Banks not subject 

to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during period, 4.78 feet at 

9.30 a. m. June 28 (discharge, 1,380 second-feet); minimum stage during 

winter.

1917-1927: Maximum stage recorded, that of June 28, 1927; minimum, 

0.66 foot at 7 a. m. March 26, 1922 (discharge, 2 second-feet exclusive of 

flow through pipe line, which was 4 second-feet).

DIVERSIONS AND REGULATION. Pipe line of Buffalo Northwest Electric Co. 

diverts water from Clear Creek 1% miles upstream; a separate record of flow 

through pipe line is kept. Four Lakes, French Creek Canal, and North Fork 

divert water from Clear Creek above station. During 1927, 10,200 acre-feet 

was diverted between June 10 and August 31. Alternate melting and 

freezing of mountain snow during spring of year cause diurnal fluctuation 

in flow.

ACCURACY. Stage-discharge relation practically permanent; affected by ice, 

observations discontinued during winter. Rating curve well defined by 

11 discharge measurements between 25 and 700 second-feet and checked by 

discharge measurement on May 22 at a discharge of 421 second-feet; extended 

beyond these limits. Gage read to quarter-tenths twice daily. Daily discharge ascertained by applying mean daily gage height to rating table. 

Records good.

 NORTH PIATTB RIVER ABOVE AND BELOW WHAUEK, WtO.

LOCATION. In sec. 11, T. 26 N., R. 65 W., at diversion dam at Whalen, Goshen 

County. Nearest large tributary, Cottonwood Canyon Creek;, an inter-, 

mittent stream, which enters 1% miles below.

DRAINAGE AREA. 16,300 square miles (measured on base map of Wyoming).

RECORDS AVAILABLE. May 1, 1909, to September 30, 1927. Records above 

Whalen represent discharge above dam, and those below Whalen quantity 

passing over dam. Difference between two records represents amount 

diverted by Interstate and Fort Laramie Canals.

EQUIPMENT. 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. Discharge through headgates of Interstate and Fort Laramie Canals is computed 

from gate openings.

DIVERSIONS AND REGULATION. Adjudicated diversions for irrigation of 38,000 

acres from North Platte River between Pathfinder and Whalen gaging station, exclusive of the diversions by the Bureau of Reclamation. Discharge 

represents chiefly effect of Pathfinder and Guernsey Reservoirs, which store 

water for use in Interstate and Fort Laramie Canals.

COOPERATION. Complete records furnished by United States Bureau of Reclamation.

NORTH FORE OF NORTH PIATTE RIVER NEAR WALDEN, COLO.

LOCATION. In sec. 29, T. 9 N., R. 80 W., at Norrell ranch, one-fourth mile above 

mouth and 7 miles west of Walden, Jackson County.

DRAINAGE ABE A. 168 square miles (measured on topographic map and special 

map in Bulletin 596).

RECORDS AVAILABLE. October 1, 1923, to September 30, 1927.

EQUIPMENT. Bristol float-type water-stage recorder on left bank opposite ranch 

house. Datum lowered 0.34 foot October 1, 1926. Discharge measurements made from cable just above recorder or by wading.

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

bar 150 feet below; shifts at infrequent intervals. Banks subject to overflow during high water.
134 SURFACE WATER SUPPLY, 1927, PART VI

EXTREMES OP DISCHARGE. Maximum stage during year, from water-stage 

recorder, 2.17 feet at 7 a. m. June 30 (discharge, 520 second-feet); minimum 

discharge probably occurred during winter.

1924-1927: Maximum stage recorded, 2.63 feet at 9 a. m. April 19, 1926 

(discharge, 694 second-feet); minimum discharge, 19 second-feet September 

16, 1924, and September 29 and 30, 1926.

DIVERSIONS AND REGULATION. Water diverted for irrigation of several hundred 

acres. Diurnal fluctuation during spring from alternate melting and freezing 

of mountain snow.

ACCURACY. Stage-discharge relation permanent during year; seriously affected 

by ice, observations discontinued during winter. Rating curve fairly well 

defined between 60 and 400 second-feet by three measurements made during 

year; extended parallel to previous curve beyond those limits. Operation 

of water-stage recorder satisfactory. Daily discharge ascertained by applying to rating table mean daily gage height obtained by inspection of recorder 

graph, using shifting-control method October 1 to November 13, except as 

indicated in footnote to table of daily discharge. Records good except those 

for estimated periods, which are fair.

Daily discharge, in second-feet, of North Fork of North Platte River near Walden, 

Colo., for the year ending September 30, 1927

LOCATION. In sec. 10, T. 8 N., R. 81 W., at highway bridge \% miles above 

mouth and 11 miles southwest of Walden, Jackson County. Nearest tributary, Beaver Creek, enters 1 mile above.

DRAINAGE AREA. 84 square miles (measured on topographic map and on geologic map in Bulletin 596).

RECORDS AVAILABLE. May 14, 1904, to October 31, 1905; October 1, 1923, to 

September 30, 1927.

EQUIPMENT. Bristol float-type water-stage recorder at left abutment of bridge. 

Discharge measurements made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of gravel. Control 50 feet below gage; 

shifts at intervals. Banks not subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage during year, from water-stage 

recorder, 3.52 feet at 9 a. m. June 19 (discharge, 628 second-feet); minimum 

discharge probably occurred during winter.

1904-5, 1923-1927: Maximum stage recorded, 3.73 feet at 6 a. m. 

June 15, 1924 (discharge, 790 second-feet); minimum, 1.02 feet (old datum) 

August 15, 1904 (discharge, 2 second-feet).

DIVERSIONS AND REGULATION. Water diverted for irrigation of several hundred 

acres. Diurnal fluctuation during spring from alternate melting and freezing 

of mountain snow.

ACCURACY. Stage-discharge relation not permanent; affected by ice, observations discontinued during winter. Rating curve used October 1 to June 19 

well defined by thirteen measurements and checked during year by measurement on May 25 at discharge of 137 second-feet. Curve used June 20 to 

September 30 fairly well defined between 40 and 600 second-feet by two 

measurements made during year. Operation of water-stage recorder satisfactory. Daily discharge ascertained by applying to rating tables mean 

daily gage height obtained by inspection of recorder graph, using shiftingcontrol method May 16-31 and June 12-19, except as indicated in footnote 

to table of daily discharge. Records fair.

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 practically permanent. Banks 

are not subject to overflow. Bed of canal composed of shale, which changes 

somewhat; principal control at concrete drop 1 mile downstream.

EXTREMES OF DISCHARGE. Laramie River: Maximum stage during year, from, 

water-stage recorder, 2.46 feet at 5 a. m. May 18 and 9 a. m. May 22 (discharge, 1,510 second-feet); minimum discharge during winter. Pioneer 

Canal: Maximum stage during year, 3.05 feet June 30 to July 7 (discharge, 

262 second-feet); minimum discharge, practically zero during winter. Combined maximum discharge, 1,560 second-feet May 22; minimum discharge 

during winter.

1912-1924, 1927: Combined maximum discharge, 5,060 second-feet June 

10, 1923; minimum discharge during winter.

DIVERSIONS AND REGULATION. Water diverted for irrigation of 700 acres from 

Laramie River between Jelm and Woods stations, exclusive of diversion by 

Pioneer Canal. No regulation, as pond above dam is too small to have any 

appreciable effect on flow. When canal head gates are closed, the discharge 

over dam increases.

ACCURACY. Laramie River: Stage-discharge relation practically permanent. 

Rating curve well defined by many measurements and checked during current 

year by a measurement May 3 at discharge of 385 second-feet. Operation 

of water-stage recorder fairly satisfactory. Daily discharge ascertained by 

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

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

Records good. Pioneer Canal: Stage-discharge relation shifts at intervals. 

Rating curve fairly well defined by seven discharge measurements, two of 

which were made during year. Water-stage recorder operated nine days in 

June; for remainder of period staff gage read at infrequent intervals. Daily 

discharge ascertained by applying mean gage height to rating table and 

interpolating for days of missing gage heights. Gage-height record so 

fragmentary that records are considered poor.

CLEAR CREEK NEAR GOLDEN, COLO.

LOCATION. In sec. 32, T. 3 S., R. 70 W., in canyon \% miles above Golden, 

Jefferson County. Only important tributary between station and mouth, 

Ralston Creek, enters 12 miles below.

DRAINAGE AREA. 392 square miles (measured on topographic map).

RECORDS AVAILABLE. May 4, 1919, to September 30, 1927. From December 

4, 1908, to December 31, 1909; June 8, 1911, to May 3, 1919, records available for station half a mile upstream where flow is practically the same.
PLATTE RIVER BASIN 153

EQUIPMENT. Bristol float-type water-stage recorder on left bank 200 feet 

upstream from Colorado & Southern Railway section house. Discharge 

measurements made from cable near gage or by wading.

CHANNEL AND CONTROL. Bed composed of coarse gravel and sand. Lowwater control at small rapids 100 feet downstream; shifting. Banks not 

subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.13 feet 

at 3 a. m. June 29 (discharge, 1,080 second-feet); minimum discharge 

during winter.

1909, 1911-1927: Maximum discharge recorded, 4,420 second-feet July 

31, 1921; minimum, 18 second-feet January 11, 1918, from current-meter 

measurement.

DIVERSIONS AND REGULATION. Only diversion above station is Golden ditch, 

which diverted 4,560 acre-feet during 1927. Alternate melting and freezing 

of mountain snow causes diurnal fluctuation during spring.

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

records discontinued during winter. Rating curves used October 1 to 

November 18 and March 28 to September 30 are both well defined between 

50 and 900 second-feet by eight discharge measurements, of which five 

were made during year. Operation of water-stage recorder satisfactory. 

Daily discharge ascertained by applying to rating table mean daily gage 

height obtained by inspection of recorder graph. Records good.

NORTH ST. VHAOT CREEK NEAR ALIENS PARE, COLO.

LOCATION. In SW. % sec. 14, T. 3 N., R. 73 W., a short distance above bridge 

on main road from Aliens Park to Estes Park and 2)£ miles north of Aliens 

Park, Boulder County. Copeland Lake outlet enters a few hundred yards 

upstream.

DRAINAGE AREA. 33 square miles (measured on topographic map).

RECORDS AVAILABLE. October 23, 1925, to September 30, 1927.

EQUIPMENT. Bristol float-type wate"r-stage recorder on left bank a short distance 

below bridge. Discharge measurements made from single-span bridge or 

by wading; during winter discharge measured by weir placed in creek near by.

CHANNEL AND CONTROL. Bed composed of gravel. Control 60 feet downstream; slightly shifting. Banks not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage 

recorder, 2.7 feet at 1 a. m. June 28 (discharge, 407 second-feet); minimum 

discharge recorded, 6.0 second-feet March 22.

1925-1927: Maximum stage recorded, 3.05 feet from 8 to 10 p. m. June 8, 

1926 (discharge, 488 second-feet); minimum discharge, that of March 22, 

1927.

DIVERSIONS AND REGULATION. Practically no diversions above station. Diurnal fluctuation caused by alternate melting and freezing of mountain snow 

during spring.

ACCURACY. Stage-discharge relation slightly shifting; weir used during winter 

kept free from ice. Standard rating curve used October 1 to November 15 

and April 17 to September 30 is well defined between 15 and 400 second-feet 

by 17 discharge measurements, 9 of which were made during year. Rating 

table used January 10 to April 16 was computed from weir table and is 

only fairly accurate because of leakage. Operation of water-stage recorder 

satisfactory during periods of open water. Height of water over weir measured to tenths of an inch twice daily during winter. Daily discharge ascertained by applying mean daily gage height to rating table except for periods 

October 1 to November 15 and April 17 to July 31, when shifting-control 

method was used, and except as indicated in footnote to table of daily discharge. Records good except those for periods of missing gage heights, 

which are fair.

MIDDLE ST. VRAIN CREEK NEAR ALIENS PARK, COLO.

LOCATION. In NW. % sec. 3, T. 2 N., R. 72 W., at Middle Fork ranch, 9 miles 

southeast of Aliens Park, Boulder County. Nearest tributary, Cave Creek, 

enters 2 miles upstream.

DRAINAGE AREA. 28 square miles (measured on topographic maps).

RECORDS AVAILABLE. April 26, 1926, to September 30, 1927.

EQUIPMENT. Bristol float-type water-stage recorder on left bank 30 feet below 

private bridge at ranch. Discharge measurements made from single-span 

bridge or by wading.

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

gravel bar 30 feet downstream; slightly shifting.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage 

recorder, 2.3 feet at 8 p. m. June 28 (discharge, 194 second-feet); minimum 

discharge, 3.9 second-feet January 13.

1926-27: Maximum stage recorded, 2.65 feet at 9 p. m. June 6, 1926 

(discharge, 322 second-feet); minimum discharge, that of January 13, 1927.

DIVERSIONS AND REGULATION. Practically no diversion above station. Diurnal 

fluctuation caused by alternate melting and freezing of mountain snow 

during spring.

ACCURACY. Stage-discharge relation slightly shifting; weir used during winter 

kept free from ice. Rating curve used October 1 to November 20 and 

April 17 to September 30 fairly well denned between 10 and 200 second-feet 

by 17 discharge measurements, 9 of which were made during current year. 

Rating table used January 12 to April 16 was computed from weir table, 

allowing for velocity of approach. Operation of water-stage recorder 

satisfactory during open water. Height of water over weir measured to 

tenths of an inch twice daily. Daily discharge ascertained by applying 

mean gage height to rating table except period May 15 to September 30 

when shifting-control method was used, and except as indicated in footnote 

to table of daily discharge. Records good.

feet September 3, 1926 (discharge, from extension of rating curve, 18,200 

second-feet); minimum discharge, 6 second-feet June 1 and July 26, 1925.

DIVERSIONS AND REGULATION. None.

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

winter. Rating curve used until April 20 fairly well defined by 11 discharge 

measurements; curve used after that date fairly well defined by 14 discharge 

measurements, 2 of which, at 15 and 217 second-feet, were made during 

the year. Gage read to hundredths once daily during low stages and twice 

daily during high stages. Daily discharge ascertained by applying mean 

daily gage height to rating table; shifting-control method used October 4 to 

February 5, based upon discharge measurement made December 3. Records 

good except those for periods of ice effect, which are poor.

PLATTE RIVER BASIN (IOWA-MISSOURI)

PIATTE RIVER AT AGENCY, MO.

LOCATION. In NE. % sec. 29, T. 56 N., R. 34 W., at highway bridge in Agency, 

Buchanan County, 600 feet below Atchison Topeka & Santa Fe Railway 

bridge and 8 miles below Third Fork.

DRAINAGE AREA. 1,790 square miles (measured on United States soil-survey 

maps and base maps of Missouri and Iowa).

RECORDS AVAILABLE. May 22, 1924, to September 30, 1927.

EQUIPMENT. Chain gage on bridge. Discharge measurements made from highway or railway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of rock and mud. Banks are overflowed at stage of 24 feet. Control is a series of rocky riffles 500 feet below 

gage; practically permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 22.22 feet at 

noon October 7 (discharge, 14,500 second-feet); minimum, 1.70 feet at 6 p. m. 

September 17 (discharge, 24 second-feet).

1924-1927: Maximum stage recorded, 26.83 feet at 6 p. m. September 18, 

1926 (discharge, 22,600 second-feet); minimum, that of September 17, 1927. 

Flood of July, 1915, reached a stage of 31.4 feet, determined by levels to 

chiseled high-water mark on bridge.

DIVERSIONS AND REGULATION. None.

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

affected by ice. Rating curve well denned below and fairly well denned 

above 2,000 second-feet by 27 discharge measurements. Three of the measurements, covering a range from 33 to 283 second-feet, were made during 

the year and check the curve closely. Gage read to hundredths twice daily. 

Daily discharge ascertained by applying mean daily gage height to rating 

table. Records good except those for periods of ice effect, which are poor.

BLACKWATER KIVER AT BLUE LICK, HO.

LOCATION. On line between sees. 27 and 34, T. 49 N., R. 21 W., at bridge on 

State highway No. 65 three-fourths mile below Finney Creek and 1 mile 

south of Blue Lick, Saline County.

DRAINAGE AREA. 1,120 square miles (measured on topographic maps).

RECORDS AVAILABLE. June 22, 1922, to September 30, 1927.

EQUIPMENT. Chain gage on bridge. Discharge measurements made from 

bridge or by wading.

CHANNEL AND CONTROL. Bed composed of hardpan and silt; shifting. Right 

bank high; left bank overflowed at stage of 30 feet. Control is gravel bar 

300 feet below gage; practically permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 32.01 feet 

at 11.10 a. m. March 22 (discharge, 17,400 second-feet); minimum, 1.63 

feet at 11.30 a. m. September 29 (discharge, 1 second-foot).

1922-1927: Maximum stage recorded, that of March 22, 1927; minimum 

discharge, 0.6 second-foot June 12 and September 1, 1925.

DIVERSIONS AND REGULATION. None.

ACCURACY. Stage-discharge relation changed during high water March 22; 

affected by ice during winter. Rating curve fairly well defined by 15 discharge measurements, five of which, between 12 and 16,900 second-feet, 

were made during the year. Gage read to hundredths once daily except 

Sundays and holidays. Daily discharge ascertained by shifting-control 

method based on one discharge measurement until March 21 and by applying 

daily gage height to rating table after that date. Records fair except 

those for periods of ice effect, which are poor.
