SURFACE WATER SUPPLY OF THE MISSOURI RIVER

BASIN, 1911.

By W. A. LAMB, W. B. FREEMAN, and EAYMOND KICHARDS.

AUTHOBITY FOB THE WORK.

This volume is Part VI of a series of 12 reports presenting results 

of measurements of flow made on certain streams in the United States 

during the calendar year 1911. The reports are listed in the following

o For the purpose of uniformity in the presentation of reports, a general plan has been agreed upon by the 

United States Reclamation Service, the United States Forest Service, the United States Weather Bureau, 

and the United States Geological Survey, according to which the area of the United States has been divided 

into 12 parts, whose boundaries coincide with natural drainage lines indicated by the parts of the report.

The data presented in these reports were collected by the United 

States Geological Survey under authority implied in the organic law 

(20 Stat. L., p. 394), which contains the following paragraph:

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 of 

water supply for irrigation.

Since the fiscal year ending June 30, 1895, successive sundry civil 

bills passed by Congress have carried the following item and appropriations :

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

for the investigation of underground currents and artesian wells and for the preparation of reports upon the best methods of utilizing the water resources. 

Annual appropriations for the fiscal year ending June 30

In the execution of the work many private and State organizations 

have cooperated. Acknowledgments for such cooperation are made 

on pages 13-14, and also in connection with the description of each 

station affected by the cooperative work.

PUBLICATIONS.

Measurements of stream flow have been made at nearly 2,000 

points in the United States, and also at many points in small areas 

in Seward Peninsula and the Yukon-Tanana region, Alaska, and in 

the Hawaiian Islands. During 1911 gaging stations were maintained 

by the Survey and the cooperating organizations at about 1,500 points 

in the United States, and many discharge measurements were made 

at other points. In connection with this work data were also collected in regard to precipitation, evaporation, storage reservoirs, 

river profiles, and water power in many sections of the country, 

and will be made available in the regular surface water supply papers 

from time to time. A complete list of the gaging stations maintained 

by the Survey to and including 1910, and a list of the papers relating 

to the water supply of the country, have been published by the Survey 

as Water-Supply Paper 280. An index to the reports containing 

stream-flow measurements prior to 1904 has been published as WaterSupply Pap er 119.

For each calendar year there has been prepared a report embodying the stream-flow data collected during that year, which has been 

published either as a part of the Annual Report of the Director, as a 

bulletin, or as a water-supply paper, as shown by the following table:

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 which represent a rate of flow, as secondfeet, gallons per minute, miner's inches, and discharge in second-feet 

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

water, as run-off in depth in inches and acre-feet. The units used in 

this series of reports are second-feet, second-feet per square mile, runoff depth in inches and acre-feet. They may be defined as follows:

"Second-foot" is an abbreviation for cubic foot per second and is 

the unit for the rate of discharge of water flowing in a stream 1 foot 

wide, 1 foot deep, at a rate of 1 foot per second. It is generally used 

as a fundamental unit from which others are computed by the use of 

the factors given in the following table of equivalents.

"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, depth in inches," is the depth to which the drainage area 

would be covered if all the water flowing from it in a given period 

were conserved and 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" is equivalent to 43,560 cubic feet and 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 work.

EXPLANATION OF DATA.

For each, regular current-meter gaging station the following data, 

so far as available, are given: Description of the station, list of discharge measurements, table of daily gage heights, table of daily 

discharge, table of monthly and yearly discharges and run-off. For 

stations located at weirs or dams the gage-height table is omitted.

In addition to statements regarding the location and installation 

of current-meter stations, the descriptions give information in regard 

to any conditions which may affect the constancy of the relation of 

gage height to discharge, covering such points as ice, logging, shifting channels, and backwater; also information regarding diversions 

which decrease the total flow at the measuring section. Statements 

are also made regarding the accuracy and reliability of the data.

The table of daily gage heights records the daily fluctuations of the 

surface of the river as found from the mean of the gage readings taken 

each day, usually in the morning and in the evening. The gage 

height given in the table represents the elevation of the surface of 

the water above the zero of the gage. All gage heights affected by 

the presence of ice in the streams or by backwater from obstructions 

are published as recorded, with suitable footnotes. The rating table 

is not applicable for such periods unless the proper corrections to the 

gage heights are known and applied. Attention is called to the fact

EXPLANATION OP DATA. 15

that the zero of the gage is placed at an arbitrary datum and has no 

relation to zero flow or the bottom of the river. In general, the zero 

is located somewhat below the lowest known flow, so that negative 

readings shall not occur.

The discharge measurements and gage heights are the base data 

from which rating tables, daily discharge tables, and monthly discharge tables are computed.

The rating table gives, either directly or by interpolation, the discharge in second-feet corresponding to every stage of the river recorded 

during the period for which it is applicable. It is not published in 

this report, but can be determined from the tables of daily gage 

heights and daily discharge as follows:

First plot the discharge measurements for the current and earlier 

years on cross-section paper, with gage heights in feet as ordinates 

and discharge in second-feet as abscissas. Then tabulate a number 

of gage heights taken from the daily gage-height table for the complete range of stage given and the corresponding discharges for the 

days selected from the daily discharge table and plot* the values on 

cross-section paper. The last points plotted will define the rating 

curve used and will lie among the plotted discharge measurements. 

After drawing the rating curve, a table can be developed by scaling 

off the discharge in second-feet for each tenth foot of gage height. 

These values should be so adjusted that the first differences shall 

always be increasing or constant, except for known backwater 

periods.

The table of daily discharge gives the discharge in second-feet 

corresponding to the observed gage heights as determined from the 

rating tables.

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

gives the mean flow, as determined from the rating table, 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 of "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 the computations for the remaining 

columns, which are denned on page 12, are based.

The field methods used in the collection of the data presented in 

this series of reports are described in the introductory sections of 

Water-Supply Papers 261 to 272, inclusive, "Surface water supply 

of the United States, 1909." Plates I and II show the average precipitation and run-off in the United States as determined from the

records of rainfall collected by the Weather Bureau; Plate III shows 

typical gaging stations; Plate IV shows current meters 1 used in the 

work.

ACCURACY AND RELIABILITY OF FIELD DATA AND 

COMPARATIVE RESULTS.

The accuracy of stream-flow data depends primarily on the natural 

conditions at the gaging station and on the methods and care with 

which the data are collected. Errors of the first group depend on 

the degree of permanency of channel and of permanency of the relation between discharge and stage.

Errors of the second class are due, first, to errors in observation of 

stage; second, to errors in measurements of flow; and, third, to errors 

due to misinterpretation of stage and flow data.

In order to give engineers and others information regarding the 

probable accuracy of the computed results, footnotes are added to the 

daily discharge tables, stating the probable accuracy of the rating 

tables used, and an accuracy column is inserted in the monthly discharge table. 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" or "approximate" 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 accuracy column in the monthly discharge table does not 

apply to the maximum or minimum nor to any individual day, but 

to the monthly mean. It is based on the accuracy of the rating, the 

probable reliability of the observer, and knowledge of local conditions. In this column A indicates that the mean monthly flow is 

probably accurate within 5 per cent; B, within 10 per cent; C, within 

15 per cent; D, within 25 per cent. Special conditions are covered 

by footnotes.

Even though the monthly means for any station may represent 

with a high degree of accuracy the quantity of water flowing past 

the gage, the figures showing discharge per square mile and depth of 

run-off in inches may be subject to gross errors which result from 

including in the measured drainage area large noncontributing districts or omitting estimates of water diverted for irrigation or other 

use, and they should therefore be considered as only approximate, 

particularly for periods of irrigation or of low Water. For these 

errors it is as a rule not feasible to make adequate correction.

In general the base data collected each year by the Survey engineers are published not only to comply with the law but to afford

any engineer the means of examining and adjusting to his own needs 

the results of the computations. The table of monthly discharge is so 

arranged as to give only a general idea of the flow at the station and 

should not be used for other than preliminary estimates. The determinations of daily discharge allow more detailed studies of the variation 

in flow by which the period of deficiency may be determined.

It should be borne in mind that the observations in each succeeding 

year may be expected to throw new light on data already collected 

and published, and the engineer who makes use of the figures presented in these papers should verify all ratings and make such 

adjustments for earlier years as may seem necessary.

COOPERATION AND ASSISTANCE. 

MONTANA.

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 State of Montana also cooperated in the work, authority having been granted by the State legislature in 1911, which passed a 

bill appropriating $3,000 for 1911 and $3,000 for 1912, to be expended 

on the work of gaging streams, 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.

Much of this fund has been expended on work in connection with 

Carey projects.

A number of stations in the western part of Montana were maintained in cooperation with the Forest Service.

Acknowledgments are due to the several Carey Land Act companies for salaries of gage observers paid during the year; to the

APPROPRIATION OF WATER.

VARIATIONS IN STATE WATER LAWS.

The water laws of -the Western States differ so widely in their 

provisions that such terms as "water filing/' "appropriation," and 

"water right" have no general application or meaning. The rights 

to water in these States rest in general, first, on the Constitution and 

statutes of the United States; second, on the respective State constitutions and the State statutes that have been enacted in accordance therewith; third, on the decisions of Federal and State courts 

in the interpretation of these various provisions of law and in their 

application to specific conditions; and, fourth, on the requirements 

of the State engineers and other officials charged with the administration of the State water laws.

In addition, the right to convey water across public lands must 

be acquired in accordance with the provisions of the acts of Congress 

and the regulations of the Secretary of the Interior and the Secretary 

of Agriculture pursuant thereto.

In this report each description of a gaging station in Colorado 

gives the number of second-feet of adjudicated diversions from the 

stream and its tributaries, to indicate as nearly as possible the extent 

to which appropriations have been recognized by the State courts. 

It does not follow, however, that this amount of water is actually 

diverted, as many of the older decrees called for amounts greatly in 

excess of those actually used; on the other hand, no account has 

been taken of filings which have not yet been perfected and adjudicated. It is impossible from the State records to reach any conclusion as to the validity of these filings or as to the probability of their 

final perfection.

CONSTITUTIONAL PROVISIONS.

COLORADO.

In common with most of the other Western States, Colorado has 

discarded the common-law doctrine of riparian rights and has established a system based upon prior appropriation. The following are 

extracts from the State constitution relative to the use of water for 

irrigation:

ARTICLE XVI.

IRRIGATION.

SEC. 5. The water of every natural stream not heretofore appropriated within the 

State of Colorado is hereby declared to be the property of the public; and the same is 

dedicated to the use of the people of the State, subject to appropriation as hereinafter 

provided.

SEC. 6. The right to divert the unappropriated waters of any natural stream to 

beneficial uses shall never be denied. Priority of appropriation shall give the better 

right as between those using the water for the same purpose; but when the waters of 

any natural stream are not sufficient for the service of all those desiring the use of the
20 SURFACE WATER SUPPLY, 1911, PART VI.

same, those using the water for domestic purposes shall have the preference over those 

claiming for any other purpose, and those using the water for agricultural purposes 

shall have preference over those using the same for manufacturing purposes.

SEC. 7. All persons and corporations shall have the right of way across public, 

private, and corporate lands for the construction of ditches, canals, and flumes for the 

purpose of conveying water for domestic purposes, for the irrigation of agricultural 

lands, and for mining and manufacturing purposes, and for drainage, upon payment 

of just compensation.

SEC. 8. The general assembly shall provide by law that the board of county commissioners, in their respective counties, shall have power, when application is made 

to them by either party interested, to establish reasonable maximum rates to be charged 

for the use of water, whether furnished by individuals or corporations.

WYOMING.

In Wyoming, as in Colorado, the courts reject riparian rights and 

the principal of prior appropriation is established in the State. The 

provisions of the State constitution regarding the appropriation and 

use of water are as follows:

ARTICLE I.

SEC. 31. Water being essential to industrial prosperity, of limited amount, and easy 

of diversion from its natural channels, its control must be in the State, which, in 

providing for its use, shall equally guard all the varied interests involved.

ARTICLE VIII.

IRRIGATION AND WATER RIGHTS.

SEC. 1. The water of all natural streams, springs, lakes, or other collection of still 

water within the boundaries of the State, are hereby declared to be the property of 

the State.

SEC. 2. There shall be constituted a board of control, to be composed of the State

engineer and superintendents of the water divisions, which shall under such regulations

as may be prescribed by law, have the supervision of the waters of the State and of

 their appropriation, distribution, and diversion and of the various officers connected

therewith. Its decisions to be subject to review by the courts of the State.

SEC. 3. Priority of appropriation for beneficial uses shall give the better right. No 

appropriation shall be denied except when such denial is demanded by the public 

interests.

SEC. 4. The legislature shall by law divide the State into four (4) water divisions 

and provide for the appointment of superintendents thereof.

SEC. 5. There shall be a State engineer who shall be appointed by the governor of 

the State and confirmed by the senate; he shall hold his office for the term of six (6) 

years or until his successor shall have been appointed and shall have qualified. He 

shall be president of the board of control and shall have general supervision of the 

waters of the State and of the officers connected with its distribution. No person 

shall be appointed to this position who has not such theoretical knowledge and such 

practical experience and skill as shall fit him for the position.

ARTICLE XIII.

SEC. 5. Municipal corporations shall have the same right as individuals to acquire 

rights by prior appropriation and otherwise to the use of water for domestic and 

municipal purposes, and the legislature shall provide by law for the exercise upon 

the part of incorporated cities, towns, and villages of the right of eminent domain 

for the purpose of acquiring from prior appropriators upon the payment of just compensation, such water as may be necessary'for the well being thereof and for domestic 

uses.
APPROPRIATION OP WATl^R. 21 

MONTANA.

The following provision in the Montana State constitution relates 

to the use of the water in the State:

[Art. 2, sec. 15.] The use of all water now appropriated, or that may hereafter be 

appropriated for sale, rental, distribution, or other beneficial use, and the right of way 

over the lands of others for all ditches, drains, flumes, qanals, and. aqueducts, necessarily used in connection therewith, as well as the sites for reservoirs necessary for 

collecting and storing the same, shall be held to be a public use.

NORTH DAKOTA.

The sole provision of the State constitution of North Dakota relative to the use of water is the following:

[Art. 17, sec. 210.] All flowing streams and natural water courses shall forever remain the property of the State for mining, irrigating, and manufacturing purposes.

SOUTH DAKOTA.

This State has no constitutional provisions relative to the use of 

water.

NEBRASKA.

The State constitution of Nebraska makes Jio provision for the use 

of water in the State.

ADMINISTRATION OF WATE& LAWS. 

COLORADO.

Appropriation of water in Colorado may b^> divided into two general classes: The direct appropriation, wherp the water is used as 

delivered from the head gates of the canal, and the appropriation for 

storage, where water from the river is not used at the time of diversion but is stored in reservoirs for future use. Appropriations of the 

second class are usually valid only during periods of high water when 

there is an excess of water over the needs of the direct appropriators. 

In the construction of reservoirs it is necessary to obtain approval of 

plans by the proper county commissioners, in addition to obtaining 

that of the State engineer, for all dams exceeding 10"feet in height. 

The entire construction of the reservoir is ujader the supervision of 

the State engineer, who has authority to require material used and 

work of construction to be done to his satisfaction. In case of failure 

of a reservoir the owners are liable for all enduing damages.

The control of water by the State is veste$ in the State engineer, 

whose duty it is to supervise the diversion <?f water by the various 

appropriators in accordance with the decrees of the State courts. 

The State is divided into five irrigation divisions, each in charge of a 

division engineer, who is under the direction of the State engineer. 

Each irrigation division is divided into a number of water districts, 

of which there are 70 for the entire State. For each water district
22 SUEFACE WATEE SUPPLY, 1911, PART VI.

there is appointed a water commissioner, whose duty it is, under the 

supervision of the division engineer, to divide the water in the 

natural streams among the several ditches taking water from the 

same, according to the rights of each. Whenever there is a scarcity 

of water he is empowered to shut down the head gates of those 

ditches whose priorities are of too recent date to entitle them to 

divert water. In the discharge of this duty he has the power of a 

constable.

WYOMING.

The constitution of the State of Wyoming creates the office of 

State engineer and divides the State into four principal water divisions, each under the control of a division superintendent. The 

State engineer and the division superintendents form a board of control having supervision of the appropriation and distribution of the 

water, subject to court review.

Rights to the use of water are begun by filing an application in 

the office of the State engineer. This application must be prepared 

in accordance with the State law and the requirements of the State 

engineer. When the application is in proper form a permit to divert 

the water and construct the works is issued.

The distribution of the water in accordance with the respective 

rights of permittees is supervised by water commissioners, one having jurisdiction in each of a large number of water districts, into 

which the four principal divisions are divided. The acts of the commissioners of any district are subject to review by the higher administrative officials, and eventually by the courts.

MONTANA.

An appropriation of water in Montana is begun by the posting of 

a notice at the proposed point of diversion, a copy of which notice 

is filed with the county clerk and recorder of the county in which the 

water is to be diverted. There is no limitation as to the amount of 

water upon which any person may file, and many streams have single 

filings upon them for more than their entire flow. Eventually, however, each appropriator can acquire the right to use only such water 

as he has put to beneficial use. Questions arising as to the rights of 

appropriators are determined by court proceedings. The State engineer has no functions relative to the diversion or distribution of 

water, but the State courts may appoint commissioners to enforce 

decrees.

Under this system examination of a stream and a search of the decrees are required to determine the title to its waters.

NORTH DAKOTA.

General supervision of matters relating to the use of water is vested 

in the State engineer, who is particularly charged with the custody
APPROPRIATION OP WATJER. 23

of records and the survey of streams. The State is divided into four 

water divisions, each in charge of a commissioner, and each division 

may be further subdivided into districts, each having a water master. 

The water commissioners, together with the State engineer, constitute 

a board empowered to make general rules for the control of water.

Appropriations made prior to the present water law are adjudicated 

by the courts, one copy of the decree being filed in the office of the 

State engineer. Applications to appropriate^ water are filed with the 

State engineer, the procedure therefor being similar to that in 

Wyoming.

NEBRASKA.

Control of water for irrigation is vested in the State board of irrigation, highways, and drainage, which consists of the governor, 

attorney general, and commissioner of public lands. The State 

engineer is appointed by the board, and acts as its secretary. The 

State is divided into two water divisions, eac|h in charge of a superintendent. Within these divisions water districts, in charge of water 

commissioners, may be created as needed, 'fhe water commissioners 

control the distribution of water to the respective appropriators.

Applications to appropriate water for irrigation are made to the 

State board in accordance with the regulations. Upon approval the 

applicant may construct the necessary work^. A certificate is finally 

issued by the State board and recorded with the county clerk.

Storage reservoirs are subject to special provisions of law, and dams 

over 10 feet high must be authorized by the board.

IBBIGATION DISTBICTS.

With the growth of irrigation in Colorado it has become necessary 

to enact laws creating irrigation districts Whereby the owners of 

adjacent lands may organize for the purpose of jointly conveying 

water to irrigate these lands. When a majority of landowners in a 

district desire to irrigate their lands, they inay petition the county 

commissioners of the county in which the greatest acreage of land is 

located to organize an irrigation district. 4jr election is then held 

by the commissioners at which all the landowners in the proposed 

district are entitled to vote on the question of organization. If the 

result of the election favors it, the irrigation district is organized and 

a board of three directors elected. This board is empowered to enter 

into contracts for completing the necessary Structures to irrigate the 

lands, and to acquire rights of way, water rights, etc. Similar statutes 

have been enacted in Wyoming, Montana, and Nebraska.

THE CABEY ACT.

The act of August 18, 1894 (28 Stat., 372, 422), commonly known 

as the Carey Act, and amendments thereto, the purpose of which is 

to aid the public-land States in the reclamation of the desert lands
24 SURFACE WATER SUPPLY, 1911, PART VI.

therein and in the settlement, cultivation, and sale of such lands in 

small tracts to actual settlers, authorize 

(a) The temporary withdrawal of public lands from settlement or 

entry pending investigation and survey preliminary to the filing of 

an appEcation for segregation, such withdrawn lands to be restored 

to settlement and entry at the end of one year from the date of 

withdrawal in case application for segregation is not theretofore 

made.

(&) The segregation of public lands by the Secretary of the Interior, contracts between the United States and any beneficiary State, 

and the reclamation of such lands by beneficiary States within 10 

years from the approval of the State's application (subject to an 

extension of five years).

(c) The patenting to any beneficiary State of any tract of reclaimed 

land when satisfactory proof is made that an ample supply of water 

to reclaim it is actually furnished.

The usual procedure under the Carey Act is about as follows:

A corporation or individual applies to the State for the withdrawal 

of certain public lands proposed for irrigation. The State thereupon 

submits to the Interior Department an application for their withdrawal. On the approval of this application the State is allowed one 

year in which to investigate the project and prepare satisfactory 

plans for reclamation. The proposing company conducts the investigation and, if a project that is considered feasible is developed, 

makes application to the State for the segregation of the irrigable 

lands and offers to contract with the State for their reclamation. 

The State thereupon applies to the Interior Department for the 

segregation of the lands under the terms of the Carey Act and its 

amendments. If the plan of irrigation is found to be feasible, the 

irrigation company responsible, and the available water supply 

adequate, the lands are segregated and the contract for their reclamation is entered into between the United States and the State. 

When the irrigation works are completed to the satisfaction of the 

Government, patent is issued to tho State or to its assigns. The 

State receives payment for the lands from the settler, and the irrigation company, either directly or through the State, receives payment 

from each settler for his proportionate share of the irrigation works 

and water rights involved.

The Tenth General Assembly of Colorado, by an act approved 

March 15, 1895, accepted the conditions and grants of land to the 

State under the provisions of the Carey Act. The subsequent State 

laws stipulate that the selection, management, and disposal of such 

lands shall be vested in the State board of land commissioners. 

Before a project is approved the engineering features must be passed 

upon by the State engineer. Similar statutes have been enacted by 

Wyoming and Montana.

RED ROCK RIVER AT LIMA, MONT.

Location. Near the Gleed ranch, 1 mile east of Lima, Mont. Principal tributaries 

below the station, Sheep and Sage creeks.

Records available. August 14, 1907, to September 30, 1911.

Drainage area. Not measured.

Gage. Chain; installed October 27, 1908, at a point just above the cable and 300 

feet farther downstream than the old staff gage which it replaced; datum of chain 

gage not the same as that of the staff gage.

Channel. Probably permanent.

Discharge measurements. At ordinary and high-water stages made from a cable 

below the gage; at extremely low stages measurements made by wading just below 

the cable section.

Winter flow. River generally remains open the entire year, as a large spring discharges into the stream just above the gage.

Diversions. Three ditches, each carrying approximately 900 miner's inches, take 

water from Red Rock above the station. The flow of water above the station is 

all appropriated, but the rights are unadjudicated.

Storage. The dam of the reservoir storing the water of the Red Rock has been 

completed, but no canals have been built. The dam is of earth with concrete 

core, is 50 feet high, and will impound 90,000 acre-feet; its top elevation is 6,700 

feet; the dam is 16 miles above Lima, Mont., and 27 miles below lower Red Rock 

Lake.

Accuracy. In general, the results obtained at this station should be good.

BEAVERHEAD RIVER AT BARRATTS, MONT.

Location. One mile above Barratts and 2 miles southwest of Dillon, Mont., in the 

SW. i SW. i sec. 20, T. 8 S., R. 9 W.

Records available. August 12, 1907, to December 31, 1911.

Drainage area. Not measured.

Gage. A standard chain gage was installed on the downstream side of the bridge 

June 22, 1908, to replace the ordinary staff gage which had previously been used; 

datum of chain gage the same as that of the staff gage.

Channel. Should not shift; rocky at the measuring section.

Discharge measurements. Made from downstream side of the bridge.

Winter flow. Stream remains open during the winter months.

Diversions. Innumerable diversions are made above the station. Decreed water 

rights, aggregating 85,866 inches of water, are filed on from Lima on Red Rock 

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

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

canal, appropriating 4,000 inches; and Beaverhead canal, diverted 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.

Beaverhead River is called Red Rock River from its source in Red Rock Lakes 

to the post office of Red Rock, below which it is called the Beaverhead. The principal tributaries to the Beaverhead above the station are Grasshopper Creek, 12 miles 

south of Dillon; Horse Prairie Creek, 20 miles south; and Rattlesnake and Blacktail 

Deer creeks. Irrigation has probably been practiced in Beaverhead Valley longer 

than in any other valley in Montana, ditches constructed in the early seventies being 

still in operation.

36 SURFACE WATER SUPPLY, 1911, PART VI.

MISSOURI RIVER AT CASCADE, MONT.

Location. At the highway bridge, 100 yards from the Great Northern Railway, on

the east side of the town of Cascade, Mont. 

Records available. July 20, 1902, to December 31, 1911. 

Drainage area. 18,300 square miles.

Gage. Standard chain gage attached to the bridge; datum unchanged. 

Channel. Probably permanent except at extreme flood stages. 

Discharge measurements. Made from lower side of bridge. 

Winter flow. Affected by ice.

The most important tributaries between this station and the station at Toston, 

above, are Dearborn River, Little Prickly Pear Creek, and Prickly Pear Creek. 

Although irrigation is extensively practiced in the Missouri River valley, the water 

is taken from the tributary streams, the Missouri itself because of its high banks and 

great variation in flow and difficulty of diversion being little used.

PRICKLY PEAR CREEK AT EAST HELENA, MONT.

Location. In NE. \ sec. 36, T. 10 N., E. 3 E., at the point where the Northern 

Pacific Railway crosses the stream at East Helena, Mont. The only important 

tributaries entering Prickly Pear Creek above the station are McClellan and Lump 

Gulch creeks; Tenmile and Silver creeks come in below.
52 SURFACE WATER SUPPLY, 1911, PART VI.

Records available. July 18, 1908, to December 31, 1911.

Drainage area. Not measured.

Gage. Staff fastened to piling on the Northern Pacific Railway bridge; datum unchanged.

Channel. Rocky, clean, and nonshifting.

Discharge measurements. Made from a highway bridge near the railway bridge 

or by wading just below the gage.

Diversions. All the normal flow of Prickly Pear Creek is used for irrigation, the 

greater part of the water being diverted below the station.

Accuracy. The bed of the stream is so extremely rough that discharge measurements 

are difficult, even in low water. Fair results have, however, been obtained.

LUMP GULCH CREEK NEAR CLANCY, MONT.

Location. In sec. 4, T. 8 N., R. 3 W., at the ranch of Charles Zastron, 1 mile from 

Clancy, 15 miles from Helena, and half a mile above the junction of the creek 

with Prickly Pear Creek.

Records available. July 15, 1908, to December 31, 1911.

Drainage area. Not measured.
54 SUEFACE WATEE SUPPLY, 1911, PAET VI.

Gage. Staff; on left bank directly south of observer's house. A new gage was set 

October 12, 1910, at the original site but at a datum 1.0 foot lower than that previously used. All gage heights for 1910 were reduced to new datum.

Channel. Gravelly, unclean, and shifting.

Discharge measurements. Made by wading.

Winter flow. Affected by ice.

Diversions. The water of Lump Gulch Creek has been extensively used for placer 

mining. At present the creek furnishes some water for irrigation, but the valley 

is narrow and affords but little irrigable land. The normal flow of the stream is 

appropriated.

Accuracy. Data not entirely satisfactory; no flood records have been obtained.

datura of the gage was lowered 1 foot on October 21, 1910, and all gage heights 

for the year were consequently changed.

Channel. Permanent.

Discharge measurements. Made from cable just above gage or by wading.

Winter flow. Stream freezes over and gage-height observations are discontinued.

Diversions. None above the station.

Accuracy. Interpolations between gage readings are believed to be fairly accurate.

Channel. Permanent except in flood.

Discharge measurements. Made by wading- or from a cable.

Winter flow. Affected by ice.

Diversions. The entire flow of this stream reaches Dearborn River.

Accuracy. Interpolations between observed gage heights believed to be fairly accurate.

' Falls Creek affords opportunities for water power development above the station, as 

its fall is large.

Location. At the highway bridge at Sun River, Mont. The principal tributaries 

of Sun River all enter above the station; South Fork of Sun River, Willow Creek, 

and Simms Creek are the most important.

Records available. July 31, 1905, to December 31, 1911.

Drainage area. Not measured.

Gage. A staff nailed to piling on the left bank just above the bridge; datum unchanged.

Channel. Shifts at all stages.

Discharge measurements. Made from bridge or by wading.

Diversions. Practically the entire valley above this point is irrigated with water 

taken from the river.

FORD CREEK NEAR AUGUSTA, MONT.

Location. At the ranch of Joseph Ford, 16 miles west of Augusta, Mont. Ford Creek

unites with Smith Creek to form the South Fork of Sun River. Ford Creek has

no tributary.

Records available. April 11, 1906, to December 31, 1911. 

Drainage area. 18 square miles.

Gage. Staff, on the right bank near the observer's house; datum unchanged. 

Channel. Shifting; current swift. 

Discharge measurements. Made by wading. 

Winter flow. Little affected by ice. 

Diversions. One irrigation ditch, capacity about 15 sec.-ft., diverts water from the

creek above the gage. 

Accuracy. As conditions of flow are changeable, frequent discharge measurements

are necessary to properly define the rating curve.

MARIAS EIVEE BASIN. 

MARIAS RIVER NEAR SHELBY, MONT.

Location. At the highway bridge near James A. Johnson's ranch, 7 miles south of 

Shelby, Mont.

Records available. April 4, 1902, to June 30, 1906; March 21 to December 31, 1911.

Drainage area. 2,610 square miles.

Gages. A standard chain gage fastened to the up-stream guardrail of the bridge was 

read during 1905-6; a Bristol automatic and a staff gage were set when the 

station was reestablished in 1911. The new gages are at practically the same 

datum as the old gage.

Channel. Straight for 100 yards above and 200 yards below the station; right bank 

sandy, sloping, and liable to overflow; left bank high and protected by sheet 

piling and a plank wall. Bed composed of sand and gravel with some cobblestones. Liable to shift after freshets. Only one channel at all stages. Current 

is of moderate velocity and sets toward the left bank as it rounds a sharp curve 

some distance above.

Discharge measurements. Made from highway bridge, lower chord of which is 

about 15 feet above low water.

Winter flow. Affected by ice.

TWO MEDICINE RIVER AT FAMILY, MONT.

Location. In the NE. \ NE. \ sec. 2, T. 31 N., R. 9 W., at the Holy Family Mission, 

16 miles southeast of Browning, Mont., and about 6 miles above the mouth of 

Badger Creek, the nearest tributary.

Records available. April, 1907, to December 31, 1911.

Drainage area. 368 square miles.

Gage.-^Standard chain on the east bank of the stream directly back of the Mission 

buildings; datum of gage was lowered 0.95 foot July 21, 1908.

Channel! Gravel.

Discharge measurements. Low-water measurements made by wading at section 

near the gage; high-water measurements must be made from the old wagon bridge 

about 3 miles above the Mission.

Winter flow. Affected by ice.

Diversions and storage. Water is diverted at a point about 2 miles above the 

gage by a ditch which supplies water for about 100 acres of land on the farm at the 

Holy Family Mission. The United States Reclamation Service has under construction a project which will use about 200 second-feet of water for irrigating land 

north of the stream for the Blackfeet Indians. The water will be diverted near 

the mouth of Little Badger Creek, a small tributary entering from the south above 

the station. A storage reservoir will be built at Two Medicine Lake near the 

headwaters of the stream to augment the low-water flow.

Accuracy. Results at this station are good except during the winter months.

BADGER CREEK NEAR FAMILY, MONT.

Location. In the NE. \ sec. 19, T. 31 N., R. 8 W., near theroad crossing, 4 miles east

of Family, Mont.

Records available. April 20, 1907, to December 31, 1911. 

Drainage area. 224 square miles. 

Gage. Chain. The original staff gage established April 20, 1907, and bench marks

were washed out in-June, 1908, and a new gage was established July 22,1908,

about 400 feet farther upstream and at a different datum; as the bench mark was

also destroyed the relation between the two gages could not be determined. The

gage was again washed out on May 25, 1909, and was reset at a different datum

and 400 feet below the old Piegan Mission crossing. 

Channel. Two channels at both medium and low stages; at high stages the stream

flows in several channels. 

Discharge measurements. High-water measurements made from a cable 4 miles

above the gage; low-water measurements can be made by wading at the ford

above the gage. 

Diversions. The "United States Reclamation Service proposes to divert the natural

flow of Badger Creek to irrigate land in the eastern part of the Blackfeet Indian

Reservation north of Birch Creek. 

Accuracy. High-water measurements are only fair; low-water records are, however,

good.

BIRCH CREEK NEAR DtTPUYER, MONT.

Location. In sec. 28, T. 29 N., R. 8 W., at Shield's ranch, 12 miles northwest of

Dupuyer, Mont., and about 25 miles above the junction of Birch Creek with Two

Medicine River.

Records available. July 25, 1907, to December 31, 1911. 

Drainage area. 155 square miles. 

Gage. A temporary staff gage was put in July 23, 1908, about 200 feet below the site

of the original gage, which had been washed out by the high water of June, 1908.

The temporary gage was used until October 1,1908, when a permanent chain gage

was installed at a point about one-fourth mile farther upstream. 

Channel. Shifts at high stages. 

Discharge measurements. Made from a car and cable three-fourths mile below

the gage. At low stages measurements are made by wading just below the cable

section.

Winter flow. Affected by ice. 

Diversions. A number of ditches divert water for irrigation. The largest of these,

owned by the Conrad Investment Co., diverts water about half a mile below the

station.

DTJPUYER CREEK AT DUPTTYER. MONT.

Location. In SW. i SW. i sec. 10, T. 28 N., R. 7 W., at the highway bridge in the 

town of Dupuyer, Mont.

Records available. April 15, 1908, to December 31, 1911.

Drainage area. Not measured.

Gage. The original staff gage was nailed to the cribbing under the east end of the 

highway bridge. The gage was washed out July 28, 1909, and was replaced 

September 20, 1909, gage readings being reduced to the original datum. In the 

spring of 1909 a breakwater was constructed on the left (west) bank which deflected 

the water to the opposite site. A new gage was installed April 25, 1910, at the 

same site and the original datum, but owing to changes in the channel, the gage 

records for 1910 and 1911 are not directly comparable with those for earlier years.

Channel. Shifts at high stages.

Discharge measurements. Made from downstream side of highway bridge at 

high stages; low-stage measurements are made by wading.

Winter flow. Affected by ice.

Accuracy. Frequent measurements are necessary at this station to insure good results 

as conditions in the channel are unfavorable.

TETON RIVER AT STRABANE.i MONT.

Location. In the SE. £ NE. \ sec. 35, T. 25 N., R 7 W., 1 mile north of Feeble's 

ranch, 16 miles above Chouteau, Mont., at Strabane post office.

Records available. November 26, 1904, to December 31, 1906; January 16, 1908, 

to December 31, 1911.

Drainage area. 140 square miles.

Gage. The original gage was spiked to a post on the left bank about 40 feet above the 

bend of Kroff's irrigation ditch. On March 9,1905, it was moved by the observer 

to a point 250 feet upstream to avoid the effect of the dam erected at the head of 

the ditch below. On May 8, 1905, the gage was referred to the bench marks and 

it was found that the datum had been raised 0.7 foot in moving; the difference 

between the level of the water surface at the old site and that at the new was 0.20 

foot; on May 8, 1906, the gage was again moved 1J miles upstream to Mr. Bjornstad's ranch and set at an entirely different datum. The station was discontinued during 1907, and when it was reestablished in 1908 a standard chain gage 

was installed on the left bank. On March 23,1911, a new station was established 

one-half mile downstream from old gage.

Channel. Shifts at high stages; current swift.

Discharge measurements. At flood stages, made from cable one-fourth mile above 

the gage; at low stages, by wading at various sections.

Winter flow. Not affected by ice.

Diversions and storage. Practically no water is diverted above the station, but 

the ordinary flow below the station is appropriated and used for irrigation. An 

irrigation project now being constructed under the Carey Act will store the flood 

water of Teton River in the reservoir about 5 miles north of the gaging section. 

The capacity of the reservoir is 90,000 acre-feet, and it can be increased to 210,000 

acre-feet by raising the top of the dam 20 feet. The reservoir will serve 120,000 

acres of land on the north side of the river. The water will be diverted half a 

mile above the gage.

Accuracy. Accurate determination of discharge during high stages is difficult because 

of the shifting channel.

1 Station was described in earlier reports as "Teton River near Belleview, Mont." Post office was 

moved from Belleview to Strabane in 1910.

104 SURFACE WATER SUPPLY, 1911, PART VI.

NORTH FORK OF MTTSSELSHELL RIVER NEAR MARTEBTSDALE, MONT.

Location. In sec. 6, T. 8 N., R. 12 E., half a mile above the junction of the North

and South Forks, at the ranch of Martin J. Settle, 4 miles north of Martinsdale. 

Records available. May 10, 1907, to December 31, 1911. 

Drainage area. Not measured. 

Gage. Chain attached to left bank just above observer's private wagon bridge;

datum unchanged. 

Channel. Composed of gravel; may shift somewhat during high-water, as current is

swift.

Discharge measurements. Made from the private wagon bridge or by wading. 

Winter flow. Affected by ice. 

Storage. Under a Carey Act project the water of the North Fork, which is practically

all appropriated, will be stored at a point about 20 miles above the station and

used to irrigate land between Martinsdale and Harlowton. 

Accuracy. Records obtained during open season are very good.

106 SUKFACE WATER SUPPLY, 1911, PAET VI,

MUSSELSHELL RIVER AT HARLOWTON, MONT.

Location. In sec. 26, T. 8 N., B. 15 E., at the highway bridge 1 mile south of Harlowton. Takes place of station formerly maintained at Shawmut.

Records available. July 11, 1907, to December 31, 1911.

Drainage area. Not measured.

Gages. The original gage was destroyed in October, 1908; on April 10,1909, a temporary staff gage was installed which read 0.73 foot too high. On May 24, 1909, a 

standard chain gage was placed on the upstream side of the new public highway 

bridge at a datum 0.52 foot higher than the bench mark and the datum of the 

bench mark was raised 0.52 foot. All gage heights for 1909 were corrected to the 

new datum.

Channel. Bed of stream composed of sand and gravel; will probably shift in flood.

Discharge measurements. Made from bridge or by wading.

Diversions. A large part of the valley is irrigated and many small ditches take water 

from the Musselshell; practically the entire flow of the stream is appropriated. A 

minimum discharge of 2 second-feet is recorded during the irrigation season at 

this station.

AMERICAN FORK NEAR HARLOWTON, MONT.

Location. At the Shaw & Elliott ranch, 5 miles southeast of Harlowton, Mont., a 

few miles above the junction of the American Fork with the Musselshell.

Records available. July 28, 1907, to December 31, 1911.

Gage. Chain fastened to upper rail of small wagon bridge; datum'unchanged.

Channel. Bed composed of sand and clay; shifts only at extremely high stages.

Discharge measurements. Made from the bridge or by wading.

Winter flow. Affected by ice.

Storage. The basin of the American Fork affords some good storage sites and by 

holding back the spring flood waters, which are derived from the melting snow on 

the mountains, much more land can be put under irrigation.

Accuracy. Open season records good.

MILK RIVER BASIN. 

SOUTH FORK OF MILK RIVER NEAR BROWNING, MONT.

Location. At Richard Croff's ranch, about 40 miles northeast of Browning, Mont.,

and about 6 miles south of the Canadian boundary line. 

Records available. April 28, 1905, to December 31/1911. 

Drainage area. 283 square miles. 

Gage. Chain. During the high water of June, 1908, the gage was washed out and

was not replaced until July 31,1908, when the new chain gage was installed at the

original site and datum.
118 SUBFACE WATER SUPPLY, 1911, PAET VI.

Channel. Permanent.

Discharge measurements. Made from a cable installed at the time of the installation of the new gage.

Winter flow. Affected by ice.

Flood discharge. The river overflows its banks at gage height of 12 feet; highwater 

marks show that,the flood of June, 1908, reached a stage of 15.4 feet on the gage. 

The flood width was 850 feet and the cross section about 2,600 square feet.

Diversions. A number of small ditches divert water to irrigate meadow lands in the 

river bottom; a considerable amount of this water returns to the stream as seepage 

and waste. No storage is used above the station.

Accuracy. Records excellent except during, the winter months.

120 SURFACE WATER SUPPLY, 1911, PART VI.

MILK RIVER AT HAVRE, MONT.

Location. In SE. J SE. J sec. 5, T. 32 N., R. 16 E., at the highway bridge over Milk 

River at Havre, Mont.

Records available. May 15, 1898, to December 31, 1911.

Drainage area. About 7,300 square miles.

Gage. Chain fastened to bridge rail on the downstream side; datum unchanged.

Channel. Shifts.

Discharge measurements. Made from bridge or by wading.

Winter flow. From the last part of November to the first part of April the river at 

Havre is frozen entirely over and in portions of the cross sections it is usually 

frozen to the bottom.

Diversions. An irrigation company in southern Alberta, Can., has been granted an 

appropriation of 500 second-feet of the low-water flow and 1,500 second-feet of the 

high-water flow, and a canal of 330 second-feet capacity has been partially constructed but no water has been diverted. There are no othej important irrigation rights above Havre, but farther downstream are five large canal systems supplied directly from Milk River and irrigating about 22,000 acres. Preliminary 

steps toward the adjudication of the water rights of these various systems have 

been taken. A suit in behalf of the Fort Belknap Indians was decided in their 

. favor with the result that they were given a prior right over the other canals to 

125 second-feet, the priority of the other rights not being touched upon. Although no provision for storage has been made by the above claimants, the entire 

unappropriated flow of the stream has been filed upon by the United States 

Reclamation Service in connection with its Milk River irrigation project now 

under construction.

Accuracy. Frequent discharge measurements are necessary to properly define the 

rating curve, and even with these the estimates are subject to considerable error. 

In years of low precipitation the flow ceases entirely and the water stands in pools 

for several months.

MH-K RIVER AT MALTA, MONT.

Location. In the NW. J sec. 17, T. 30 N., R. 30 E., at the highway bridge at Malta, 

Mont.

Records available. July 31, 1902, to December 31, 1911.

Drainage area. About 14,000 square miles.

Gage. Chain fastened to handrail on downstream side of bridge; datum unchanged.

Channel. Sandy; shifts during floods.

Discharge measurements. Made from bridge or by wading.

Winter flow. More or less ice present during winter months.

Diversions. The-entire run-off from the drainage area above does not pass the station, 

for between Havre and Malta seven irrigation canals, which irrigate about 25,000 

acres of land, divert water from Milk River and its tributaries. The United States 

Reclamation Service has under construction a diversion dam at Dodson about 17 

miles above the station, which will divert water for the irrigation of about 108,000 

acres of land in Milk River valley. East of Malta there are two canals, one on 

each side, the combined discharge being 1,000 second-feet.

NORTH FORK OF MILK RIVER NEAR CHINOOK, MONT.

Location. Tn sec. 3, T. 33 N., R. 19 E., at a point about 4£ miles north of Chinook, 

Mont., about 7 miles above the junction of the North Fork with the main stream.

Records available. April 22, 1905, to December 31, 1911.

Drainage area. Not measured.

Gage. Chain on the left bank near the house of the observer.

Channel. Sandy and shifting.

Discharge measurements. Made by wading or at the cable near the gage.

Winter flow. Ice present; gage readings impracticable.

Diversions. Three canals, which divert in the aggregate about 20 second-feet, take 

out above the station; several small pumping plants, which supply water for irrigating the bottom land along the river valley, also operate above the station. 

Below the station the Matheson and Cook canals divert water for irrigating land in 

Milk River Valley near the mouth of the North Fork. The aggregate appropriation for these canals is 78 second-feet.

Accuracy. Results may be considered reliable as a fair rating curve has been constructed. The greater part of the run-off occurs during floods caused by heavy 

rains in the spring and early summer. In the fall the channel is often dry.

BEAVER CREEK NEAR SACO.i MONT.

Location. In sec. 35, T. 31 N., R. 32 E., at Craig's ranch, 3 miles south of Ashfield,

Mont., near Saco, the nearest post office, and about 18 miles from Malta. 

Records available. July 5, 1903, to November 4, 1911.

1 Station described in earlier reports as "Beaver Creek near Ashfield, Mont," 

8173° WSP 306 14 9
130 STJEFACE WATEE SUPPLY, 1911, PAET VI.

Drainage area. Not measured.

Gage. Staff. The gage was first established at bridge No. 455 of the Great Northern 

Railway, half a mile west of Ashfield; it was moved to its present location, 2£ miles 

farther upstream, December 31, 1903.

Channel. The stream carries little water except at the times of the spring floods or 

heavy rains; during the summer months the channel is obstructed by a dense 

growth of weeds and willows, which have to be cleared out occasionally. At 

medium and high stages a second channel, known as Beaver Creek Overflow, 

receives the stream above the station, fills a depression to the west of the main 

channel, and reenters at a point some distance below the gage.

Discharge measurements. Made from a cable or by wading.

Winter now. Ice present during the winter months.

Diversions. Water is diverted from Beaver Creek by small ditches leading from the 

stream and by small pumping plants near the banks.

Accuracy. Results are only fair, as the growth of weeds and willowa in the channel 

the construction of a permanent rating curve difficult. Daily discharge 

for days with gage heights only; no monthly estimates have been made.

BEAVER CREEK OVERFLOW NEAR BOWDOIN, MONT.

Location. In the SW. J sec. 17, T. 30 N., R. 32 E., at John TurmelPs ranch, 14 miles

from Malta, Mont. 

Records available. June 29,1903, to August 30, 1906; May 2,1908, to December 31,

1910; March 20 to November 11, 1911. 

Gage. Staff; datum unchanged. 

Channel. Water flows in this channel only when Beaver Creek is high; during the

remainder of the season the water is standing in pools and fluctuations in water

level are due wholly to local rains and to evaporation. 

Discharge measurements. At flood stages made at a bridge half a mile below the

gage; low-water measurements are made by wading near the gage. 

Accuracy. Records poor. Lack of measurements in 1911 has prevented the making

of estimates of daily and monthly discharge.

PRIVATE CANALS IN MILK RIVER VALLEY. 

GENERAL FEATURES.

Since 1905 a number of stations have been maintained on private 

canals in Milk River valley for the purpose of ascertaining the extent 

of private water rights. With the exception of Rock Creek Canal, 

which is near Hinsdale, in Valley County, these canals are located in 

Chouteau County and are used to irrigate lands in the vicinity of 

Harlem and Chinook.

The canals are all built on small grades and in soil which is easily 

eroded. In many of them silt has been deposited, and nearly all of 

them contain a growth of weeds and moss. At low stages the' water 

is uniformly sluggish. In order to divert water into the laterals 

checks are erected in the main canals, and these checks often produce 

back-water effects for long distances above. They were put up under 

a great variety of conditions, and as a result velocities are found to 

differ widely at the same gage height during the season. In order to 

establish the correct relation between gage height and discharge it 

is necessary to make several rating curves for the same canal station. 

Frequent discharge measurements are necessary to obtain reliable 

results. Staff gages are located on all canals and most measurements 

are made by wading.

PARADISE VALLEY CANAL NEAR CHINOOK, MONT.

YELLOWSTONE RIVER AT HTTNTLEY, MONT.

Location. In the SW. i sec. 24, T. 2 N., R. 27 E., at the new steel highway bridge 1 

mile below Huntley, Mont., 1 mile below Pry or Creek. Station replaces that 

formerly maintained at Junction.

Records available. October 1, 1907, to December 31, 1911.

Drainage area. 12,000 square miles.

Gage. Chain fastened to bridge rail; datum unchanged.

Channel. Shifts .

Discharge measurements. Made from downstream side of bridge.

Winter flow. River frozen entirely over in places during the winter, but during 

the coldest seasons open channels with floating ice are not of uncommon occurDiversions. The Huntley canal, built by the United States Reclamation Service, 

takes water from the river about 2 miles above the gaging station; its normal 

capacity is 400 second-feet, and it supplies the water for 29,000 acres of land. 

Near Laurel are the headgates of the Billings Land & Irrigation Co. 's canal, which 

carries about 305 second-feet and irrigates 28,000 acres. Many small ditches take 

water from the tributaries of the Yellowstone, but few from the stream itself, 

owing to the variation of the stage of the water surface and consequent difficulty 

of diversion.

Accuracy. Conditions for obtaining accurate data at this station are only fair and 

many discharge measurements are necessary to define a good rating curve.

YELLOWSTONE RIVER AT LOWER YELLOWSTONE DAM, AT INTAKE, MONT.

Location. At the Lower Yellowstone diversion dam, at Intake and 18 miles 

below Glendive, Mont.

Records available.-^Records by War Department and Department of Agriculture, 

1893 to 1903; August 1, 1903, to December 31, 1911, by United States Geological 

Survey. Records January 1 to December 31, 1911, from observations at the present station, which replaces the one formerly maintained at Glendive.

Gage. A chain gage on the north abutment of the dam. The gage readings show the 

depth of water on the crest of the dam.

Winter flow. Affected by ice.

The dam. The dam, a rock-filled timber-crib structure on a pile foundation, was 

completed January 29, 1910. It is 700 feet long, crosses the stream at right angles 

to the current, and will raise the low-water level of the river about 4 feet. The 

dam is specially designed to resist the destructive effects of ice by having an 

approach on a slope of 3 to 1, and the downstream face is ogee-shaped and protected by a heavy rock apron.

Diversions. The Lower Yellowstone canal, which diverts water to irrigate 66,000 

acres of land, has its headworks at the north abutment.

Accuracy. A curve showing relation of gage heights at Glendive and at Lower 

Yellowstone dam was constructed. Using this curve of relation and discharge 

measurements made at Glendive, a discharge curve was constructed which is 

applicable to the gage heights of Lower Yellowstone dam, and should give fair 

results.

NORTH FORK OF BIG TIMBER CREEK WEAR BIG TIMBER, MONT.

Location. In the SE. £ SE. £ Bee. 26, T. 3 N., K. 13 E., 1 mile above the Tintinger

ranch, 15 miles northwest of Big Timber, Mont., just above the junction with the

South Fork.

Records available. May 6, 1907, to December 31, 1911. 

Drainage area. 40 square miles. 

Gage. Staff on left bank; datum unchanged.

Channel. Bed composed of bowlders and coarse gravel; probably permanent. 

Discharge measurements. Made by wading. 

Winter flow. Affected by ice. 

Diversions. Several ditches above the station divert water to irrigate approximately

300 acres of land; a large ditch appropriating 50,000 inches of water (including

both forks) heads just below the gage. The water rights of Big Timber Creek

have never been adjudicated. 

Storage. Two lakes at the head of the North Fork offer excellent reservoir sites.

It is proposed to utilize the flow of the North Fork in connection with a project

under the Carey Act. 

Accuracy. Results obtained during the open season good.

YELLOWSTONE BIVEB BASIN. 165

SWEETGKASS CREEK ABOVE MELVILLE, MONT.

Location. In the SW. i sec. 24, T. 5 N., R. 12 E., at 0. M. Rein's ranch, 17 miles 

northwest of Melville and 35 miles from Big Timber, at the site of a reservoir proposed under the Carey Act.

Records available. May 5, 1907, to September 30, 1911.

Drainage area. 47 square miles (total for stream).

Gage. A staff nailed to lower side (right bank) of a footbridge directly behind the 

ranch buildings. When the station was established a secondary staff gage to be 

used during extreme high water was installed about 300 feet below the regular 

gage and at a different datum. The regular gage was undermined during the 

high water of June and July, 1908, and readings were discontinued August 19 of 

that year. The present gage, which is the old secondary gage, has been read since 

October 1,1908. The gage heights on the new gage are not comparable with those 

read on the old gage.

Channel. Composed of rough gravel.

Discharge measurements. Made by wading near gage at ordinary stages; at high 

stages made from footbridge.

Winter flow. Stream freezes over during winter months.

Diversions. Two small ditches divert water above the station.

SWEETGRASS CREEK BELOW MELVILLE, MONT.

Location. At McAllister's ranch, just above the head of the canal owned by the 

Glass-Lindsay Land Co.

Records available. May 4, 1907 (at Adam's ranch site), to April 1,1909; new site 

April 1, 1909, to August 31, 1911.

Drainage area. Total for stream, 47 square miles.

Gage. Staff, on left bank near observer's house; the original gage was located 2J 

miles below the headgat^ of the Glass-Lindsay Land Co.'s canal, 9 miles below 

Melville and 20 miles from Big Timber. The present gage was installed April 1, 

1909, when the old station was discontinued.

Channel. Bed composed of clean gravel; nonshifting.

Discharge measurements. Made by wading.

Winter flow. Affected by ice.

Diversions and storage. Many diversions are made from this stream. All the 

low-water flow is appropriated, 550 second-feet being held by adjudicated rights. 

The Glass-Lindsay canal will carry 575 second-feet and irrigate 30,000 acres; the 

canal will divert water into two storage reservoirs with capacities of 12,000 and 

6,000 feet, respectively, which will be filled from the spring run-off.

Accuracy. Records good.

WIND RIVER AT RIVERTON, WYO.

Location. At highway bridge in sec. 2, T. 1 S., R. 4 E., three-fourths of a mile east 

of Riverton and three-fourths of a mile above its junction with Little Wind River.

Records available. May 15 to November 11, 1911. From May 14, 1906, to November 1, 1908, a station was maintained at Walker's ferry, about 1 mile above the 

present station. As no streams enter between, the records at the two points are 

comparable.

Drainage area. 2,090 square miles (measured from Land Office map).

Gage. Chain gage.

Channel. Shifting after high water.

Discharge measurements. Made from bridge.

Winter flow. Ice causes backwater during the winter months.

Diversions. Prior to July 1, 1912, there were adjudicated diversions of 34 secondfeet from Wind River above the station, and of 91 second-feet from tributaries 

entering above.

Accuracy. Conditions are favorable for accurate results and the estimates should be 

reliable.

Cooperation. Station maintained in cooperation with the State engineer.

LITTLE WIND RIVER BELOW ARAPAHOE, WTO.

Location. At highway bridge in sec. 23,T.1S.,E.3E., one-half mile below Arapahoe. 

. Popo Agie River enters 200 yards above. Little Wind River enters Wind River 

6 miles below, and between the station and mouth Beaver Creek enters.

Records available. May 11, 1906, to November 27, 1909; May 14 to November 11, 

1911.

Drainage area. Not measured.

Gage. Vertical staff; datum unchanged since it was originally placed in 1906. From 

June 19 to July 19, 1911, a temporary gage was used whose datum was 2.95 feet 

higher. This was replaced on the latter date by a gage reading to the original 

datum. All readings are referred to the original datum.

Channel. Slightly shifting.

Discharge measurements. Made from highway bridge.

Winter flow. The river is frozen over during the winter months and the records are 

discontinued.

Diversions. Prior to July 1, 1912, there were adjudicated diversions of 4.3 secondfeet from Little Wind River and diversions of 563 second-feet from the Popo Agie 

and tributaries.

Accuracy. Although there is a slight shift, frequent measurements have defined this, 

and the estimates should be reliable. ,

Cooperation. Station maintained in cooperation with the State engineer.

POPO AGIE RIVER NEAR LANDER, WYO.

Location. On the Middle Fork, in the Yellowstone National Forest, at the ranger

station in sec. 24, T. 32 N., R. 101W. The nearest tributary enters several miles

below.

Records available. April 1 to November 9, 1911. 

Drainage area. Not measured. 

Gage. Staff gage used until June 17, 1911, when it was washed out by high water.

A new staff gage was installed reading 7.86 feet higher than the original gage.

All readings have been referred to the latter gage. 

Channel. Apparently permanent. 

Discharge measurements. Made by wading.
YELLOWSTONE RIVER BASIN. 191

Winter flow. Ice causes backwater during the winter months and the records are

discontinued. 

Diversions. Appropriations amounting to 164 second-feet have been adjudicated

on this stream prior to July 1, 1912. Very nearly all of this water is diverted

below the station. 

Accuracy. Owing to a lack of high-water measurements, no estimates of discharge

have been made. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

LITTLE POPO AGIE RIVER AT HUDSON, WYO.

Location. A short distance below the highway bridge three-eighths of a mile southwest of Hudson. No tributary between the station and the mouth of the river. 

Records available. August 26, 1907, to December 31, 1909; June 19 to November

' 11, 1911. 

Drainage area. Approximately 360 square miles.
192 SURFACE WATER SUPPLY, 1911, PART VI.

Gage. Chain gage. The original gage was located at the highway bridge. On June

13, 1908, a chain^gage was installed at the present site, at a somewhat different

datum, but was set to read the same as the original gage for the stage at which

it was installed.

Channel. Practically permanent. 

Discharge measurements. Made from the highway bridge during high water and

by wading during low stages. 

Winter flow. Ice causes backwater during the winter months and the records are

discontinued. 

Diversions. Prior to July 1, 1912, adjudicated diversions from Little Popo Agie

River above the station amounted to 49 second-feet and from the tributaries 20

second-feet. 

Accuracy. As the station has not been completely rated no estimates of discharge

have been made. 

Cooperation. Station maintained in cooperation with the State engineer.

LITTLE BIGHORN RIVER NEAR CROW AGENCY, MONT.

Location. At the Chicago, Burlington & Quincy Kailroad bridge 2 miles south of 

Crow Agency, Mont., in W. | sec. 18, T. 3 S., E. 35 E., about 14 miles above the 

junction -with Bighorn River.

Records available. March 24,1905, to June 30,1906; September 7,1911, to December 31, 1911.

Gage. Vertical staff attached to downstream end of a pile bridge pier. The records 

from March 24, 1905, to June 30, 1906, were obtained from a standard chain gage 

attached to the upstream side of the railroad bridge at Crow Agency, about 2 miles 

farther downstream. No tributaries enter between these two points.

Channel. Permanent, broken by the piers of the bridge. Bed of the stream is coarse 

gravel and cobblestones. Current is sluggish at the gage.

Discharge measurements. Made from downstream side of the bridge; low-water 

measurements are made by wading at the ford about 75 feet above the bridge.

Winter flow. Affected by ice, which forms at the control below the bridge.

Diversion. None.

SHOSHONE RIVER AT CORBETT DAM, WYO.

Location. In the NE. J sec. 7, T. 53 N., R. 100 W., at the Corbett diversion dam, 8 

miles below Cody, Wyo.

Records available. April 20, 1908, to October 25, 1911.

Drainage area. Not measured at this station; the drainage area above Cody is 

1,400 square miles. Sage Creek, the only important tributary that enters between this station and Cody, drains only about 25 square miles.

Gage. Forty feet above the crest of the dam; readings represent height of water 

above crest.*

Determinations of discharge. The discharge is computed by considering the 

dam as a weir and the sluice tunnel gates as submerged orifices. The dam is of 

reinforced concrete, of the buttressed type, having on the upstream side a deck 

2J 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; the length 

between abutments is 400 feet.

Cooperation. Gage heights and gate openings furnished by the United States 

Reclamation Service.

The following discharge measurement was made by B. E. Jones at the highway 

bridge at Cody: 

August 7, 1911: Gage height, 1.83 feet; discharge, 3,720 second-feet.

Diversions. The only diversion above the station is a log flume which heads 15 miles 

above. One hundred feet below the station is the intake for the Highline Community ditch. Prior to July 1, 1912, there were adjudicated diversions from 

Tongue River amounting to 213 second-feet in Wyoming.

Accuracy. Owing to a lack of discharge measurements no estimates of flow have been 

made.

Cooperation. Station is maintained in cooperation with the United States Forest 

Service.

The following discharge measurement was made by H. B. Waha: 

October 24, 1911: Gage height, 1.50 feet; discharge, 63 second-feet.

GOOSE CREEK AT SHERIDAN, WYO.

Location. At footbridge in city park at Sheridan, Wyo.

Records available. From April 10, 1896, to August 1, 1897, and from May 14 to 

December 31, 1911.

Drainage area. Not measured.

Gage. Vertical staff attached to under pier of the footbridge. The gage readings 

from April 10, 1896, to August, 1897, were made from a gage at the Fifth Avenue 

Bridge, below the mouth of Little Goose Creek.

Channel. Practically permanent; bed of stream is composed of gravel and cobblestones.

Discharge measurements. Made from the footbridge at high stages and by wading at low stages.

Winter flow. Gage heights during winter months are affected by ice at the gage.

Diversion. During the irrigation season the greater part of the flow is diverted for 

irrigation above the gage. About 7,500 acre-feet of water are stored in the mountains on the headwaters of the stream and diverted in the Little Goose Creek 

drainage area. There are also a number of smaller diversions into the Little 

Goose Creek drainage area after the stream leaves the mountains. The records 

at the station show the amount of water that is not used in the Big Goose drainage 

basin.

LITTLE GOOSE CREEK AT SHERIDAN, WYO.

Location. At the footbridge about 200 yards above the point where the stream

parallels the Chicago, Burlington & Quincy Railroad and about one-fourth mile

above the junction with Goose Creek at Sheridan, Wyo.

Records available. May 1, 1896, to August 1, 1897; May 14 to December 31, 1911. 

Gage. A staff attached to the downstream end of the right abutment of the footbridge.

The gage read from May 1, 1896, to August 1, 1897, was at the Broadway Bridge,

600 feet below the site of the present gage.

Channel. Liable to shift; bed of stream is composed of sand and gravel. 

Discharge measurements. Made from the downstream side of the footbridge;

low-water measurements are made by wading. 

Winter flow. Stream freezes solid at the control below gage. 

Diversions. During the irrigation season, from May to September, the greater part

of the stream is diverted for irrigation above the station. The records at this

point show the amount of water that is not being used for irrigation. 

Accuracy. Results for 1911 are believed to be good. The shifting character of the

channel may affect future results.

NORTH FORK OF POWDER RIVER NEAR KAYCEE, W7O.

Location. At Jacob Affalter's ranch, on the county road 4 miles north of Kaycee, Wyo.

Records available. May 11 to December 31, 1911.

Drainage area. Not measured.

Gage. An overhanging chain gage on the left bank one-fourth mile above the highway bridge. From May 11 to July 28, 1911, the gage was located 200 feet farther 

upstream and at a different datum. It was moved because it was within the 

influence of backwater from beaver dams.

Channel. Practically permanent. The bed of the stream at the point of control 

below the gage is composed of permanent gravel and cobblestones, but at the gage 

it is composed of sand and gravel and is liable to shift during high stages.

Discharge measurements. Made from the highway bridge one-fourth mile below 

the gage at high stages and by wading near the gage at low and medium stages.

Winter flow. Gage heights are affected by ice during the winter months. The 

channel water is frozen solid at times.

Diversions. During the irrigation season the greater part of the flow of the stream is 

diverted above the station.

Accuracy. Fair. Gage heights before July 28 were affected by backwater from a 

beaver dam below the gage. After July 28 the records are considered good.

CLEAR CREEK NEAR BUFFALO, WYO.

Location.- In the Bighorn National Forest, at Camp Comfort, in the SW. J sec. 8, 

T. 50 N., R. 83 W., 11 miles west of Buffalo; three-fourths of a mile below the 

junction of the North and South forks.

Records available. October 22, to December 31, 1911. From May 1, 1896, to 

March 11, 1900, a station was maintained by the State engineer at a point 4 miles 

west of Buffalo, where a measuring flume was built. From October 24, 1902, to 

December 31, 1904, a station was maintained at Buffalo. The records at the two 

points are not directly comparable, as a number of irrigation ditches divert water 

between and a few intermittent tributaries enter.

Drainage area. 110 square miles (measured from topographic sheets.)

Gage. Vertical staff.

Channel. Data too meager to determine.

Discharge measurements. Made from bridge during high water and by wading 

at ordinary stages.

Winter flow. Ice causes backwater during the winter months.

Diversions. There are no diversions above the station and the records at this point 

represent the natural run-off. Below the station, however, there were adjudicated diversions amounting to 333 second-feet prior to July 1, 1912.

Accuracy. Owing to a lack of discharge measurements no estimates of flow have been 

made.

Cooperation. Station maintained in cooperation with the United States Forest

Service.

The following discharge measurement was made by H. B. Waha. 

October 22, 1911: Gage height, .90 feet; discharge, 26 second-feet.

Daily gage height, in feet, of Clear Creek near Buffalo, Wyo., for 1911.

LITTLE MISSOURI RIVER NEAR ALZADA, MONT.

Location. At Walker's ranch, 2 miles below the mouth of Thompson Creek, near 

the southwest corner of T. 8 N., R. 60 E., 300 yards below a proposed dam site and 

4 miles below Alzada, Mont. Alzada is most conveniently reached by stage or by 

automobile from Belle Fourche, S. Dak.

Records available. April 30, 1904, to November 30, 1906; June 18 to December 31, 

1911.

Drainage area. About 780 square miles.

Gage. Vertical staff on left bank.

Channel. May shift during high water. Stream, sluggish; banks cut 5 to 15 feet in 

the sandy soil.

Discharge measurements. At ordinary stages made by wading; at flood stages 

must be measured by making one measurement of the Little Missouri from the 

bridge at Alzada and one of Thompson Creek from the bridge 2 miles above its 

mouth, and adding the results.

Winter flow. Probably affected by ice.

The following discharge measurement waa made by Mahon and Heidel: 

June 18, 1911: Gage height, 0.6 foot; discharge estimated, 1.5 second-feet.

Daily gage height, in feet, of Little Missouri River near Alzada, Mont., for 1911.

HEART EIVEE BASIN. 227

HEAET EIVEE BASIN. 

HEART RIVER NEAR HI CHARD TON, N. DAK.

Location. In or near sec. 21, T. 138 N., R. 92 W., about 11 miles south of Richardton, 

opposite the observer's house, which is 1 mile below the highway bridge at which 

the station was formerly maintained.

Records available. May 18, 1903, to September 30, 1911.

Drainage area. 1,250 square miles.

Gage. Readings in 1911, up to September 4, were obtained from a staff gage set in 

the margin of the channel at the ford about 30 rods above observer's house and 

about 1 mile below the highway bridge. This staff gage and the chain gage at the 

highway bridge were found to give identical readings until about May 15, when 

slides into the river below the highway bridge caused the gage heights at highway 

bridge to be worthless. On September 4, 1911, an overhanging chain gage was 

installed opposite the observer's house, its zero being set so that a reading of 3.3 

on the rod gage 30 rods above is 23.3 on the chain gage. On account of a beaver 

dam below the gage, readings during October are uncertain.

Channel. Not permanent.

Discharge measurements. At high stages, made from bridge; at ordinary and low 

stages, by wading.

Winter flow. Affected by ice.

Accuracy. Sufficient high and medium stage measurements have not yet been 

made to define the upper part of the rating curve.

CANNONBALL RIVER BASIN. 

CANNONBALL RIVER NEAR STEVENSON, N. DAK.

Location. On the west side of the river near the south side of sec. 23, T. 133 N., R. 

82 W., at M. H. Burdick's house, immediately above the ford, about 1 mile southeast of the Stevenson schoolhouse and about 5 miles above Timmer, N. Dak. 

This station is about 1 mile above the gage at the old Stevenson station, at which 

observations are still occasionally made.

Records available. June 10,1903, to November 30,1908; August 9 to December 31, 

1911.

Drainage area. 3,670 square miles.

Gages. Standard chain on projecting cantilever timber; a temporary rod gage on the 

left bank was used until the chain gage was ready.

Channel. Bed of stream composed of gravel and stones, in places covered with silt 

to the depth of 1 foot. At the rapids 600 feet below the gage the bed is of clean 

gravel and stones. During floods the silt may be washed away and later redeposited at some points.

Discharge measurements. At low and medium stages made by wading at the 

ford 15 rods below the gage or at the riffle 55 rods below; at medium and high stages 

measurements may be made by use of the car and cable at the old Stevenson 

station, about 1 mile farther downstream. The discharge is practically the same 

at the two points, except that a small draw, which enters midway between the 

gage and the cable on the north side, carries a small flow for a few hours after a 

rain.

Winter now. Affected by ice.

GEAND EIVEE BASIN. 

NORTH BRANCH OF GRAND RIVER AT HALEY, N. DAK.

Location. About 20 rods south of the post office at Haley, N. Dak., near the northeast corner of sec. 36, T. 129 N., R. 100 W.

Records available. May 17, 1908, to December 31, 1911.

Drainage area. 500 square miles.

Gage. Staff.

Channel. Bed of stream composed of gravel and silt.

Discharge measurements. At high stages made from car and cable 200 feet below 

gage; at low stages by wading. 

Winter flow. Affected by ice.

Accuracy. The gage heights obtained at this station are not of sufficient value to 

publish as the observer did not read the gage so long as there was no visible change 

in the flow, but recorded the same gage height day after day. However, he states 

that he kept close watch of the stream and that there was no perceptible change 

during the spring until the last of June, when it dropped suddenly about 0.2 in 

gage height, as he had recorded. The flow during the rest of the season after 

August 13, when a hydrographer visited the station, probably varied only slightly.

WHITE RIVER BASIN. 

WHITE RIVER NEAR INTERIOR, S. DAK.

Location. At the steel highway bridge near the southwest corner of sec. 7, T. 4 S., 

R. 18 E., where the county line between Stanley and Pennington counties intersects White River, 3 miles southwest of Interior, S. Dak., a station on the Chicago, 

Milwaukee & St. Paul Railway.

Records available. June 24, 1904, to November 30, 1906, at old station in T. 3 S., 

R. 18 E.; August 24 to November 30, 1911.

Drainage area. 4,090 square miles. The area above the present site is about 15 

square miles less than the area above the station maintained during 1904-1906 

near Westover.

Gage. A vertical rod attached to the lower side of the first pier (nearest the shore) at 

the left end of the bridge, installed August 31,1911, and supposed to read the same 

as the temporary rod gage which was placed August 24 on a tree on the left bank 

at the turn of the river near the southwest corner of NW. J sec. 17.

Channel. Probably changes gradually; bed composed of sand and some quicksand; 

left bank steep and clean; right bank gently sloping and clean; current, medium. 

At low stages all the water may pass under one span (67-foot); at the highest stage 

the water passes under two 67-foot spans and 120 feet of trestle approach, but probably two-thirds of the flow passes under the two spans.

Discharge measurements. Made from the highway bridge.

NIOBRARA RIVER BASIN. 

NIOBRARA RIVER AT NIOBRARA, NEBR.

Location. At the Government highway bridge spanning the main channel in the 

SE. i sec. 18, T. 32 N., R. 56 W., half a mile from the depot at Niobrara. The 

station is 1J miles above the mouth. No tributaries enter below.

Records available. August 19, 1910, to October 5, 1911. From May 11 to October 

25,1902, a station was maintained at a highway bridge 1 mile southwest of Niobrara.

Drainage area. Not measured.

Gage. Vertical staff.

Channel. Shifting and within the influence of backwater from Missouri River.

Discharge measurements. Made from bridge.

Winter flow. During the winter months ice causes backwater for short periods.

Diversions. Prior to September 1, 1912, there were approved diversions of 561 

second-feet for irrigation and 2,755 second-feet for power from Niobrara River 

above the station. There were also approved diversions of 180 second-feet for 

irrigation and 453 second-feet for power from tributaries entering above. In 

Wyoming there are adjudicated diversions of 24 second-feet from the Niobrara and 

tributaries.

Accuracy. Owing to the shifting channel and insufficient discharge measurements, 

no estimates of discharge have been made.

Cooperation. Station maintained in cooperation with the State engineer, by whom 

the field data are furnished.

BIG SIOUX RIVER BASIN. 

ROCK RIVER AT LUVERNE, MINN.

Location. At the Rock Island Railroad bridge at Luverne, Minn., 3J miles above

the mouth of Elk Creek.

Becords available. August 23, 1911, to December 31, 1911. 

Drainage area. 440 square miles. 

Gage. Vertical staff. 

Channel. Probably permanent; small rapids just below gage: severe floods will cause

Discharge measurements. Made from the railroad bridge at flood stage, from the 

highway bridge at medium stage, and at a wading section in low water.

Winter flow. From December to March the river is frozen over at the station and 

measurements are made through the ice to determine the winter discharge.

Artificial control. The flow of the river is not artificially controlled above Luverne, 

aa there are no dams except a low rock dam a short distance above the station, 

which does not regulate the flow but simply raises the water level about 2 feet.

Cooperation. Station maintained in cooperation with the State Drainage Commission.

PLATTE RIVER BASIN. 

NORTH PLATTE RIVER AT SARATOGA, WYO.

Location. At highway bridge in Saratoga, 2 miles below the mouth of Spring Creek,

Records available. June 9,1903, to October 31, 1906; April 1 to December 17, 1909; 

April 27 to November 10, 1911.

Drainage area. 2,920 square miles. Measured from Land Office maps.

Gage. A chain gage was installed at the bridge in 1911. The original gage was a 

vertical staff located 100 yards below the bridge. The relation between the two 

gages has not been determined.

Channel. Practically permanent, except that tie drives may cause backwater for a 

few days.

Discharge measurements. Made from bridge.

Winter flow. Ice causes backwater during the winter months, and the records are 

discontinued.

Diversions. Prior to July 1, 1912, there were adjudicated diversions of 86 secondfeet, from the North Platte above Saratoga, in Wyoming, and 934 second-feet from 

tributaries entering above. In the Colorado portion of the drainage area there are 

adjudicated decrees for diversions of 3,060 second-feet from the headwaters of the 

North Platte.

Accuracy. Conditions are favorable for accurate results and the estimates should be 

reliable.

Cooperation. Station maintained in cooperation with the State engineer.

Channel. Condition not known, as only final results are furnished.

Discharge measurements. Made from car and cable.

Winter flow. Ice causes slight backwater for short periods.

Controlled flow. The Pathfinder dam, one-fourth mile above the station, forms a 

reservoir of 1,025,000 acre-feet capacity. This reservoir materially changes the 

natural run-off of the river, as is seen by a comparison with the records of inflow.

Diversions. Prior to July 1, 1912, there were adjudicated diversions of 58 secondfeet from the North Platte between Saratoga and Pathfinder, and 1,550 second-feet 

from intervening tributaries. Near Whalen, 150 miles below, the water from the 

Pathfinder reservoir is diverted by the interstate canal and used to irrigate land 

in Nebraska and Wyoming. Further canals are contemplated by the Reclamation Service.

Cooperation. Station maintained in cooperation with United States Reclamation 

Service, by which the records are furnished.

The following discharge measurement was made by H. D. Comstock: 

May 25, 1911: Gage height, 3.40 feet; discharge, 1,640 second-feet.
238 SUKFACE WATEE SUPPLY, 1911, PAET VI.

Daily gage height, in feet, of North Platte River at Pathfinder, Wyo.,for 1911.

NORTH PX.ATTE RIVER AND INTERSTATE CANAL AT WHALEN, WYO.

Location. At the head of the Interstate canal at Whalen, in sec. 11, T. 26 N., R. 65 

W. The nearest important tributary is Cottonwood Canyon Creek, an intermittent 

stream which enters 1J miles below.

Records available. May 1,1909, to December 31,1911. These records represent the 

discharge passing the overfall weir at Whalen and also the amount of water passing 

the head gates of the canal, which are located just above the Whalen weir. From 

June 14,1900, to November 17,1908, a station was maintained at Guernsey. The 

flow between the two points is very nearly comparable, as only a few intermittent 

tributaries enter between the two points.

Drainage area. Not measured.

Gage. To determine the flow over the weir a vertical staff is used, its zero being at 

the weir crest. The discharge is then computed by a weir formula. There are 

also four sluice gates in the dam, through which the discharge is computed. There 

is also a second gage in the river 75 feet downstream from the crest gage, having 

its zero 10.00 feet below that of the weir gage. This latter gage is only used in 

computing the discharge through the gates when the openings are submerged. 

The discharge through the head gates of the canal is computed from the nine gate 

openings. There is a vertical staff located in the canal 1,000 feet below the head 

gates, which is used in computing the discharge when the head-gate openings are 

submerged.

Discharge measurements. In order to check the coefficients used in the discharge 

computations, a car and cable have been erected 1 mile downstream. Sufficient 

measurements have not yet been made to complete the checking.

Artificial control. The discharge represents largely the effect of the Pathfinder 

reservoir which stores water for use in the Interstate canal.

Diversions. Prior to July 1, 1912, there were adjudicated diversions from North 

Platte River of 319 second-feet between Pathfinder reservoir and the WyomingNebraska line, exclusive of the diversion by the United States Reclamation 

Service. It is not known what percentage of these diversions is above the stations.

Cooperation. Station maintained by the United States Reclamation Service, by 

which the records are furnished.

NORTH PLATTE RIVER NEAR MITCHELL, ITEBR.

Location. At highway bridge 1 mile south of Mitchell, on line between sees. 27 and

28, T. 23 N., R. 56 W. The nearest tributary is Spottedtail Creek, an intermittent

stream entering just below the station. The only important tributary between the

station and the Wyoming line is Horse Creek. 

Records available. June 3, 1901, to December 23, 1911. From May 29, 1897, to

October 31,1900, a station was maintained near Gehring. Although no tributaries

enter between the two points, the records are not directly comparable during the

irrigation season, as water is diverted for irrigation. 

Drainage area. 24,400 square miles.

Gage. Chain gage; datum lowered 1.00 foot on May 3,1902, to avoid negative readings. 

Channel. Very slightly shifting. 

Discharge measurements. Made from bridge. 

Winter flow. The river is frozen over during the winter months and records are

discontinued. 

Artificial control. The Pathfinder reservoir of the United States Reclamation

Service controls the flow at this station to a certain extent. 

Diversions. Prior to September 1, 1912, there were approved diversions of 2,188

second-feet from the North Platte between the Wyoming-Nebraska line and

Mitchell, and 75 second-feet from intervening tributaries. 

Accuracy. Conditions are favorable for accurate results and the estimates should be

reliable. 

Cooperation. Station maintained in cooperation with the State engineer, by whom

the field data are furnished.

NORTH PLATTE RIVER AT NORTH PLATTE, BTEBR.

Location. At highway bridge half a mile north of North Platte, in sec. 28, T. 14 N.,

R. 30 W., 1 mile below mouth of Scout Creek and 4J miles above the junction with

the South Platte.

Records available. February 25, 1895, to December 23, 1911. 

Drainage area. 28,500 square miles. 

Gage. A staff gage installed October 15, 1910. From October 5, 1894, to May 31,

1910, the gage was a vertical staff at the railroad bridge 2 miles east of North Platte.

On March 25, 1910, the station was moved 2 miles upstream to its present site and

a chain gage reading to a different datum was installed. This gage was stolen

July 1,1910, and the records interrupted until October 15, 1910, when the present

gage reading to a different datum was placed in position. 

Channel. Very shifting.

Discharge measurements. Made from highway bridge. 

Winter flow. The river frequently freezes to the bottom during the winter, as it is

very shallow. 

Diversions. Prior to September 1, 1912, there were approved diversions of 3,626

second-feet from the North Platte between Mitchell and North Platte, and 927

second-feet from intervening tributaries. 

Accuracy. Owing to the very shifting channel the estimates have been obtained by

the indirect method and can be considered only fair. 

Cooperation. Station maintained in cooperation with the State engineer, by whom

the field data were furnished.

PLATTE RIVER NEAR COLUMBUS, NEBR.

Location. At Meridian bridge 3 miles south of Columbus on line between sec. 36, 

T. 17 N., R. 1 W., and sec. 31, T. 17 N., R. 1 E., about 10 miles below the mouth 

of Prairie Creek and 5 miles above the mouth of Loup River.

Records available. June 4, 1895, to December 31, 1911.

Drainage area. 56,900 square miles.

Gage. A chain gage installed July 25, 1910. The bridge and the original gage previously used were washed out early in 1910. The new gage is at the same point as 

the old, but its datum is possibly slightly different. The datum of the original 

gage was unchanged up to the time of its destruction.

Channel. Extremely shifting; at this point the river flows in the channels known as 

the main, middle, and south channels. The gage is located in the main channel.

Discharge measurements. Made from bridges spanning each channel.

Winter flow. The river freezes over during the winter and records are discontinued.

Diversions. Prior to September 1, 1912, there were approved diversions of 4,888 

second-feet for irrigation and 1,500 second-feet for power from Platte River 

between the junction of the two branches and Columbus, and this diversion, 

together with the evaporation from the wide shallow channels, frequently causes 

the flow to cease at this point during the late summer and fall.

Accuracy. The extremely shifting channel makes it impossible to make estimates 

of daily discharge without almost weekly discharge measurements, as the gage 

heights are little if any index of the flow.

Cooperation. Station maintained in cooperation with the State engineer, by whom 

the field data were furnished.

junction with the South Fork, 6 miles below. This station is in the Cheyenne 

National Forest.

Records available. Fragmentary records, June 21 to September 24, 1911.

Drainage area. Not measured.

Gage. Vertical staff.

Channel. Data too meager to determine condition.

Discharge measurements. Made by wading.

Winter flow. No information.

Diversions. No water is diverted above the station, and therefore the records represent the natural run-off.
PLATTE EIVEB BASIN. 251

Accuracy. Owing to insufficient data no estimates of flow can be made. 

Cooperation. Station maintained in cooperation with the State engineer.

The following discharge measurement was made by R. H. Fletcher: 

June 21,1911: Gage height, 1.90 feet; discharge, 72 second-feet.

Drainage area. Fifty-seven square miles (measured from Forest atlas).

Gage. Vertical staff.

Channel. Somewhat shifting. 

Discharge measurements. Made by wading.

Diversions. No water is diverted above the station, and therefore the records represent the natural flow. Prior to July 1, 1912, there were adjudicated diversions 

for 3 second-feet below the station. From North French Creek there is an adjudicated diversion of 4 second-feet.

Accuracy. Conditions are favorable for good results, and the estimates should be 

reliable.

ENCAMPMENT RIVER AT ENCAMPMENT, WYO.

Location. At the lower end of the smelter grounds at Encampment, in sec. 6, T. 14 

N., R. 83 W. The nearest tributary is the North Fork, which enters 1 mile above.

Records available. May 2 to November 10, 1911.

Drainage area. 235 square miles (measured from topographic sheets and King's 

Atlas).

Gage. Chain gage type.
PLATTE KIVEB BASIN. 255

Channel. A short distance below the station is a low diversion dam which may cause 

backwater whenever additional brush x>r drift collects on its crest.

Discharge measurements. Made from car and cable.

Winter flow. Ice causes backwater during the winter months, and the records are 

discontinued.

Diversions. Three large irrigation ditches divert water at a p0int 1 mile above the 

station. The smelter company has a pipe line which divert^ water above the station, but as the tailrace of the power plant which the pipe line supplies is located 

just above the station, the amount diverted passes the gage. Water is also diverted 

below the station. Prior to July 1, 1912, there were adjudicated diversions from 

Encampment River amounting to 61 second-feet and from tributaries entering 

above 31 second-feet.

Accuracy. The lodging of de*bris on the point of control makes the conditions somewhat uncertain, and therefore the estimates of flow can not be considered better 

than fair or possibly good.

Cooperation. Station maintained in cooperation with the State engineer.

COW CREEK NEAR SARATOGA, WYO.

Location. At highway bridge in sec. 36, T. 16 N., R. 84 W., and 9 miles south of 

Saratoga. There are no tributaries between the station and the mouth, 4 miles 

below. Calf Creek enters about 2 miles above.

Records available. May 3, 1911, to October 31, 1911.

Drainage area. Not measured.

Gage. Vertical staff.

Channel. Shifting.

Discharge measurements. Made from bridge during high water, and by wading 

at ordinary stages.
PLATTE EIVEE BASIN 257

Winter flow. Ice causes backwater during the wintor months and the records are

discontinued. 

Diversions. Prior to July 1, 1912, there were adjudicated diversions from Cow

Creek of 84 second-feet and from its tributaries, 27 second-feet, nearly all above

the station. 

Accuracy. Owing to the shifting channel the estimates have been obtained by the

indirect method and can only be considered fair. 

Cooperation. Station maintained in cooperation with the State engineer.

SPRING CREEK NEAR SARATOGA, WYO.

Location. At highway bridge, in sec. 23, T. 17 N , B. 84 W., and 2 miles southwest

of Saratoga. There is no tributary between the station and the mouth, three -

fourths of a mile below.

Records available. May 3 to October 31, 1911. 

Drainage area. Not measured. 

Gage. Vertical staff. 

Channel. Somewhat shifting. 

Discharge measurements. Made from bridge during high water and by wading

at ordinary stages.

Diversions. Prior to July 1, 1912, there were adjudicated diversions of 5 second-feet 

 from Spring Creek, 85 second-feet from North Spring Creek, and 104 second-feet

from South Spring Creek. These diversions are all above the station. 

Accuracy. Owing to the somewhat shifting channel the estimates of discharge can

not be considered better than fair or possibly good. 

Cooperation. Station maintained in cooperation with the State engineer.

ROCK CREEK NEAR ARLINGTON, WYO.

Location. At highway bridge in sec. 25, T. 19 N., R. 79 W., 1| miles upstream from 

Arlington post office; 1 mile below the mouth of Overland Creek, the nearest 

tributary.

Records available. April 22 to November 4, 1911.'

Drainage area. 70 square miles (measured from Forest Service Atlas).

Gage. Vertical staff.

Channel. Shifting.

Discharge measurements. Made from bridge.

Winter flow. Ice causes backwater during the winter months and the records are 

discontinued.

Diversions. One small ditch diverts water above the station for irrigation.

Accuracy. As the channel shifts the estimates have been obtained by the indirect 

method and can be considered only fair except for those months when the measurements indicated no shift, when they are probably good.

Cooperation. Station maintained in cooperation with the State engineer and the 

Rock Creek Conservation Co.

BOXELDER CREEK NEAR CAREYHURST, WYO.

Location. At highway bridge in sec. 7, T. 33 N., R. 73 W., 1 mile south of Careyhurst. No tributary between the station and the mouth, 1 mile below. The 

nearest tributary is a small stream about 2 miles above.

Records available. May 17 to October 31, 1911. 

Drainage area. Not measured.

Gage. Vertical staff.

Channel. Data too meager to determine.

Discharge measurements. Made from bridge.

Diversions. Prior to July 1, 1912, there were adjudicated diversions from Boxelder 

Creek of 51 second-feet, and from the tributaries, 46 second-feet. All these diversions are above the station.

Accuracy. As only three discharge measurements have been made the estimates of 

flow can be considered only fair.

Cooperation. Station maintained in cooperation with the State engineer.

LARAMIE RIVER AT GLENDEVEY, COLO.

Location. At highway bridge one-eighth mile west of Glendevey in sec. 36, T. 10 N., 

R. 76 W., in the Medicine Bow National Forest; Mclntyre Creek enters a short 

distance below and Spring Creek above.

Records available. June 24,1904, to October 31,1905; August 18, 1910, to November 30, 1911.

Drainage area. 102 square miles * (measured from Clason's 1911 sectional map of 

Colorado).

Gage. Automatic gage installed by the State engineer November 17, 1910, replaced 

vertical staff previously used. The datum of the gages has remained constant.

Channel. Permanent.

Discharge measurements. Made from cable at bridge during high water and by 

wading at ordinary stages.

Winter now. Ice causes backwater during the winter months.

Diversions. There are court decrees for diversions of 65 second-feet from Laramie 

River above the station and for 749 second-feet from tributaries entering above. 

Of this latter amount 688 second-feet are for diversion into the Cache La Poudre 

basin.

i Revised since previous reports.
270 SURFACE WATER SUPPLY, 1911, PART VI.

Accuracy. Conditions are favorable for excellent results, and the estimates should 

be reliable.

Cooperation. Since its reestablishment the station has been maintained in cooperation with the State engineer and the United States Forest Service.

LARAMIE RIVER NEAR JELM, WYO.

Location. At highway bridge in sec. 15, T. 12 N., R. 77 W., 4 miles south of Jelm 

post office, one-fourth mile below the Colorado-Wyoming line.

Records available. May 7 to November 30,1911. From June 22, 1904, to October 

31, 1905, a station was maintained at Decker's ranch, half *a mile south of the 

State line. The records at the two stations are practically comparable as there 

are no tributaries nor diversions of any amount between.

Drainage area. 365 square miles (Clason's 1911 sectional map of Colorado).

Gage. In 1911 an automatic recording gage was installed by the State engineer of 

Colorado. This is referred to the same datum as the vertical staff used at first.

Channel. Practically permanent.

Discharge measurements. Made from bridge.
272 SURFACE WATER SUPPLY, 1M1, PART VI.

Winter flow. Ice causes backwater during the winter months and the records are 

discontinued.

Diversions. Between this station and that at Glendevey, Colo., there are court 

decrees for diversions of 236 second-feet from Laramie River and 204 second-feet 

from intervening tributaries. These diversions are all in Colorado.

Accuracy. Conditions are favorable for accurate results, and the estimates should be 

excellent.

Cooperation. Station maintained in cooperation with the State engineers of Colorado and Wyoming.

LARAMIE RIVER AT WOODS LANDING, WYO.

Location. At highway bridge at Woods Landing, in sec. 11, T. 13 N., R. 77 W., a 

short distance below the mouth of Wood Creek, the nearest tributary.

Records available. May 7 to November 11, 1911. During 1889, 1890, and 1891 a 

station was maintained at Woods Landing by the State engineer, and the results 

were published in his reports. From April 12, 1896, to September 30, 1900, a 

station was maintained at a point 400 feet above the present site, and as no streams 

intervene nor ditches divert water the records at the two points are comparable.

Drainage area. Not measured.

Gage. Vertical staff; no determined relation between present gage and gages used 

prior to 1900.

Channel. A short distance below the bridge there is a diversion dam which is the 

control point for the station. As this dam is not permanent conditions are somewhat changeable.

Discharge measurements. Made from bridge during high stages and by wading 

at ordinary stages.

Winter flow. Ice causes backwater during the winter months and the records are 

discontinued.

Diversions. Practically no water is diverted between the stations near Jelm and 

Woods Landing.

Cooperation. During 1911 station was maintained in cooperation with the State 

engineer.

NOTE. Ice caused backwater NOT}. 20 to Dec. 31, and it is probable that gage heights were affected by 

ice during January, February, and itfarch; approximate thickness of ice during December, 0.3 foot.

Erroneously called the South Fork in 1910 report.
284 SUKPACE WATER SUPPLY, 1911, PAET VI.

SOUTH FORK OF SOUTH PLATTE RIVER AT LAKE GEORGE, COLO.

Location. At highway bridge in sec. 19, T. 12 S., R. 71 W., one-fourth mile below

Lake George, in the Pike National Forest, about 2 miles above the mouth of Caylor Gulch; no tributary between the outlet of the lake and the station. 

Records available. October 22, 1910, to December 31, 1911. 

Drainage area. Not measured. 

Gage. Automatic recording gage installed in 1911, reading to the same datum as

the original staff gage. 

Channel. Conditions in the channel will remain unchanged as long as the control

for the station a 2-foot timber-crib dam 50 feet below the gage remains permanent. 

Discharge measurements. Made from bridge during high water and by wading at

ordinary stages. 

Winter flow. Ice causes backwater during the winter months and measurements

are made to determine the flow. 

Artificial control. The discharge at the station is controlled naturally to some

extent by the regulating effect of Lake George, which has an area of one-half

square mile. 

Diversions. There are court decrees for diversions of 1,076 second-feet from the South

Fork above this station and for diversions of 1,816 second-feet from tributaries

entering above. 

Accuracy. As the station has not been completely rated, no estimates of discharge

have been made. 

Cooperation. Station maintained in cooperation with United States Forest Service

and the State engineer of Colorado.

SOUTH FORK OF SOUTH PLATTE RIVER AT SOUTH PLATTE, COLO.

Location. In sec. 25, T. 7 S,, R. 70 W., in the Pike National Forest, half a mile east 

of South Platte, 600 feet above junction with the North Fork.

Records available. May 8j 1905, to December 31, 1911.

Drainage area. 2,160 squajre miles.

Gage. Inclined staff; datunj unchanged.

Channel. Somewhat shifting.

Discharge measurements. Made from car and cable during highwater and by 

wading at ordinary stages.

Winter flow. Ice causes backwater during the winter months and measurements 

are made to determine the flow.

Artificial control. The floto is controlled to a certain extent by the Cheeseman 

reservoir, 20 miles upstream, which has a capacity of 79,000 acre-feet. No very 

important tributaries enter between the reservoir and this station.

Diversions. There are no c<?urt decrees for diversions from the South Fork between 

this station and the one at Lake George; but decrees for diversion of 1,400 secondfeet from intervening tributaries.

Accuracy. Although the channel is somewhat shifting, sufficient discharge measure, 

ments have been made to enable reliable estimates of discharge to be made.

Cooperation. Station maintained in cooperation with the State engineer.

NOTE. Monthly estimates for this station for 1910, as published in Water Supply Paper 286, are in error, 

and the revised values are published herewith.

SOUTH PLATTE RIVER AT SOUTH PLATTE, COLO.

Location. In sec. 25, T. 7 S., R. 70 W., in the Pike National Forest, three-fourths of 

a mile east of South Platte; about 300 feet below junction of the North and South 

forks; no tributary between the forks and the station, and none for several miles 

below.

Records available. March 28, 1902, to December 31, 1911. Records at Platte 

Canyon and at Deansbury, a few miles below, extend back to 1887 with the exception of the years 1893 and 1894. The earlier records, 1887-1892, were taken by 

the State engineer, and the records from 1895 to 1898 were taken under the direction of the Denver Power & Irrigation Co.

Drainage area. 2,610 square miles.

Gage. An automatic recording gage, installed by the State engineer March 14,1910. 

From March 28,1902, to May 7,1905, the gage was at the highway bridge. On the 

latter date it was moved to its present site, 150 feet below. It is probable that the 

new gage read to a somewhat different datum. The recording gage is referred to 

the datum of the gage established in 1905.

Channel. Shifting.

Discharge measurements. Made from car and cable during high water, and by 

wading at low stages.

Winter flow. Ice causes backwater during a portion of the winter months and 

measurements are made to determine the flow.

Artificial control. The flow is controlled to a certain extent by the Cheesman 

reservoir which is on the South Fork about 20 miles above the forks.
PLATTE RIVER BASIN". 289

Diversions. No water is diverted between this station and that on the South Fork 

at South Platte nor between this station and that on the North Fork at Cassells.

Accuracy. Although the channel is shifting, sufficient discharge measurements have 

been obtained to enable fair estimates of discharge to be made.

Cooperation. Station maintained in cooperation with the State engineer.

NOTE. Monthly estimates for this station, for 1910, as published in Water Supply Paper 

error, and therefore the revised estimates are published herewith.
292 SURFACE WATER SUPPLY, 1911, PART VI.

SOUTH FLATTE RIVER AT DENVER, COLO.

Location. At the Sixteenth Street viaduct in Denver; 500 feet below mouth of 

Cherry Creek.

Records available. May 7, 1895, to December 31, 1911.

Drainage area. 3,840 square miles.

Gage. Automatic recording gage installed August 12, 1909. The original gage was 

located at the Twenty-third Street viaduct. In July, 1895, a new gage was 

installed at the Fifteenth Street bridge. In August, 1898, aft inclined staff gage 

was placed on the opposite side of the river, but referred to the same datum. 

This gage was destroyed by high, water in June, 1900, and for the remainder of the 

year the gage installed in July, 1895, was used. This gage was stolen, and a new 

one was placed between the Fifteenth Avenue and Sixteenth Avenue bridges 

May 15, 1901, reading to the same datum. This gage also was stolen and was 

replaced on June 10, 1903, by a vertical staff near the same place and having the 

same datum. The automatic gage is referred to practically the same datum as 

the preceding vertical staff.

Channel. Shifting.

Discharge measurements. Made from the Fifteenth Street bridge during high 

water and by wading at low-water stages.

Winter flow. The flow at this point is seldom affected by ice.

Diversions. Between this station and the one at South Platte there are court decrees 

for diversion from South Platte River of 2,226 second-feet and from intervening 

tributaries of 1,466 second-feet.

Cooperation. Since 1907 station has been maintained by the State engineer, by 

whom the records are furnished.

Records available. April 27,1901, to October 31,1903; March 1,1905, to December 

31, 1911.

Drainage area. 9,500 square miles.

Gage. A chain gage, placed in the fall of 1906 in each of the two channels in which 

the river flows. These gages were referred to a datum slightly different from that 

of the original gage, but have remained permanent since. The original gage, a 

vertical staff, was used until June 14, 1906, when the observer moved it 20 feet 

south. This gage was placed 0.30 foot too high, and all readings were corrected 

by that amount until the chain gages were placed in position.

Channel. Shifting.

Discharge measurements. Made from the bridge during high water and by wading at ordinary stages.

Winter flow. Ice causes slight backwater for a few days during the winter.

Diversions. Between this station and Denver there are court decrees for diversions 

of 3,764 second-feet from the South Platte, and 17,000 second-feet from intervening tributaries, besides numerous flood-water decrees.

Accuracy. Although the channel is shifting, sufficient discharge measurements have 

been obtained to enable estimates of flow to be made which may be regarded as 

reliable.

Cooperation. Station maintained in cooperation with the State engineer.

Discharge measurements of South Platte River near Kersey, Colo., in 1911.

NOTE. These estimates represent the combined flow of both channels.

SOUTH PLATTE RIVER AT JTTLESBURG, COLO.

Location. At highway bridge 1 mile south of Julesburg, about sec. 33, T. 12 N., R.

44 W. No important tributaries between the station and the Colorado-Nebraska

State line, 1 mile distant. All the tributaries for 100 miles or more above the

station are intermittent. 

Records available. April 2,1902, to November 16,1906; May 12,1908, to December

31,1911. 

Drainage area. 20,600 square miles.
298 SUKFACE WATEB SUPPLY, 1911, PAET VI.

Gage. When the station was reestablished in 1908 a gage was placed in each of the 

two main channels; both gages read practically the same as the original gage on 

the lower bridge 2,000 feet below the present site. The datum of the gages has 

remained unchanged.

Channel. Shifting.

Discharge measurements. Made from the pile bridge during high water, and by 

wading at low-water stages.

Winter flow. Ice causes backwater during the winter months and measurements 

are made to determine the flow.

Diversions. Between Kersey and Julesburg there are court decrees for diversions 

of 5,316 second-feet from the South Platte, and diversions of 1,240 second-feet 

from intervening tributaries including Lodgepole Creek in Wyoming and Nebraska 

and Crow Creek in Wyoming, besides numerous flood decrees. Between the State 

line and the mouth diversions of 206 second-feet from the South Platte have been 

granted in Nebraska.

Accuracy. Allhough the channel is shifting, sufficient measurements have been 

made to give fairly reliable discharge estimates.

Cooperation. During 1911 this station was maintained in cooperation with the State 

engineer.

PLATTE KIVEE BASIN, 305

NORTH FORK OF SOTJTH PLATTE RIVER AT GRANT, COLO.

Location. At Grant post office, in sec. 9, T. 7 S., R. 74 W., in the Pike National 

Forest, 250 feet above the mouth of Geneva Creek.

Records available. July 18, 1910, to December 31, 1911.

Drainage area. 51 square miles (measured from Forest Atlas).

Gage. Vertical staff.

Channel. Shifting.

Discharge measurements. Made from footbridge and by wading.

Winter flow. Ice causes backwater during the winter months and measurements 

are made to determine the flow.

Diversions. There are no court decrees for diversions from the North Fork above 

the station, but there is a decree for a diversion of 8 second-feet from a tributary.

Accuracy. Though the channel is somewhat shifting, sufficient measurements were 

obtained to make the estimates reliable. The diurnal fluctuations at this station 

are so great that the mean of two daily readings does not represent the mean discharge, especially in the spring, when the creek is melting during day and freezing during night.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

NORTH FORK OF SOTJTH PLATTE RIVER AT CASSELLS, COLO.

Location. At Cassells, in sec. 11, T. 7 S., E. 74 W., in the Pike National Forest.

The nearest tributary is a small stream entering from the south, a short distance

below.

Records available. July 4, 1908, to December 31, 1911. 

Drainage area. 128 square miles (measured from topographic sheets and Forest

Gage. Chain gage which replaced a vertical staff reading to the same datum.

Channel. Shifting.

Discharge measurements. Made from bridge.

Winter flow. Ice causes backwater during the winter months and measurements

are made to determine the flow. 

Diversions. There are no court decrees for diversions between this station and that

at Grant.
PLATTE BIVEE BASIN. 307

Accuracy. Although the channel is shifting, sufficient measurements have been 

obtained to make the estimates of discharge reliable. The diurnal fluctuations 

due to melting during the day and freezing at night are so great at this station 

during the spring and, to a less extent, in the fall, that the mean of .two dailygage 

readings does not properly represent the mean stage.

Cooperation. Station maintained in cooperation with the United States Forest 

Service and the State engineer.

above Grant.

Records available. Fragmentary records from August 17, 1909, to September 2, 

1911.

Drainage area. Not measured. v

Gage. Vertical staff; datum unchanged.

Channel. Unstable, as the flow is frequently affected by backwater from beaver 

dams.

Discharge measurements. Made by wading.

Winter flow. Ice causes backwater during the winter months.

Diversions. No water is diverted above the station, and therefore the records represent the natural run-off.

Accuracy. Data insufficient for estimates of discharge.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

GENEVA CREEK AT SULLIVAN'S RANCH, NEAR GRANT, COLO.

'Location. In Pike National Forest in sec. 29, T. 6 S., E. 74 W., 4 miles above Grant, 

at Sullivan's ranch; 40 feet below the mouth of Threemile Creek.

Records available. July 5, 1908, to November 3, 1911.

Drainage area. 66 square miles (measured from Forest atlas).

Gage. Vertical staff; datum unchanged.

Channel. Fairly permanent except during high water.

Discharge measurements. Made by wading.

Winter flow. Ice causes backwater during the winter months.

Diversions. There are no court decrees for diversion of water above this station, and 

therefore the records probably represent the natural run-off.

Accuracy. Conditions are favorable for good results, and the estimates of discharge 

should be reliable. The stream is, however, subject to sharp diurnal fluctuations, 

especially in the spring and, to a less extent, in the fall, caused by melting during 

the day and freezing at night, so that the mean gage height derived from two daily 

readings may not represent the true stage.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

SCOTT GOMER CHEEK 1 NEAR GRANT, COLO.

Location. Near Sullivan's ranch, in sec. 19, T. 6 S., R. 74 W., in the Pike National 

Forest, about 5 miles above Grant, one-fourth mile above mouth of creek. No 

tributary enters between mouth and station.

Records available. Fragmentary records August 16, 1909, to December 31,1911.

Drainage area. 21 square miles (measured from topographic sheet).

Gage. Vertical staff, moved to its present location, 2f miles below original site, 

September 4, 1909. Datum unchanged in new location, but has no determined 

relation to datum of original gage.

Channel. Slightly shifting.

Discharge measurements. Made by wading.

Winter flow. Ice causes backwater during the winter months.

Diversions. There are no court decrees for diversions above this station, and therefore the records probably represent the natural run-off.

Accuracy. Conditions are favorable for fairly accurate results and the estimates of 

flow should be reliable.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

CLEAR CREEK AT IDAHO SPRINGS, COLO.

Location. At Idaho Springs, in sec.-36, T. 3 S., R. 73 W., half a mile below mouth 

of Chicago Creek and a quarter of a mile above entrance of Soda Creek and Virginia Canyon.

Records available. October 8, 1910, to December 31, 1911.

Drainage area. 239 square miles (measured from Forest Atlas).

Gage. A staff gage placed March 23,1911, a short distance upstream from the original 

staff gage, which was used until that date. The new gage was referred to a datum 

0.2 foot lower than the original. All readings have been referred to the latter

Channel. Slightly shifting.

Discharge measurements. Made by wading.

Winter flow. Ice causes backwater during the winter months.

Diversions. There are no court decrees for diversions above the station, but the 

records do not represent the natural flow at all times, as water is diverted from 

Fraser River, in the Grand Basin, into Clear Creek by means of a tunnel and 

canal entering the West Fork. This diversion has a court decree for 53 secondfeet.

Accuracy. Conditions are favorable for fairly accurate results.

Artificial control. The operation of two power plants some 12 miles above the station causes a daily fluctuation of 0.10 foot or more at the gage during the low-water 

period.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

318 SUBFACE WATER SUPPLY, 1911, PAET VI.

CLEAR CREEK AT FORKSCREEK, COLO.

Location. At Forkscreek, a few hundred feet below the mouth of North Clear Creek,

Records available. May 29, 1899, to December 31, 1911.

Drainage area. 345 square miles.

Gage. A chain gage was installed June 3,1907, 50 feet upstream from first site. The

original gage had been moved 30 feet upstream on July 19, 1905, but set to read

the same as before. The chain gage was also referred to the same datum. 

Channel. Very shifting.

Discharge measurements. Made from footbridge and by wading. 

Winter flow. Ice causes backwater during the winter months and measurements are

made to determine the flow. 

Diversions. There are no court decrees for diversions between Idaho Springs and

Forkscreek. Below there are decrees for diversions of 1,668 second-feet from

Clear Creek. 

Artificial control. The natural flow is regulated to some extent by storage in various

ponds and reservoirs above. 

Accuracy. Estimates have been made by the indirect method for shifting channels

and can be considered in general only fair although the 1911 estimates have

been rated as good. 

Cooperation. Station maintained in cooperation with the State engineer.

BOULDER CREEK AT ORODELL, COLO.

Location. At Orodell station in sec. 27, T. 1 N., R. 71 W.; just below mouth of 

Fourmile Creek.

Records available. March 18, 1907, to November 30, 1911. From May 14,1895, to 

December 20, 1909, a station was maintained about 1 mile below the present site, 

chiefly by the State engineer. The records at the two points are not directly 

comparable, as some water is diverted for irrigation between. From 1902 to 1906 

the records for the lower station were published only in the reports of the State 

engineer.

8173° WSP 306 14 21
322 SURFACE WATER SUPPLY, 1911, PART VI.

Drainage area. 108 square miles (State engineer's report).

Gage. Automatic recording gage installed by the Central Colorado Power Co.

Channel. Not known, as only the computed records are furnished.

Discharge measurements. Made from car and cable.

Winter flow. Ice causes backwater during the winter months and during that

period discharge measurements are made to determine the flow. 

Diversions. There are no diversions from Boulder Creek above the station but there

are court decrees for diversions of 165 second-feet from tributaries entering above.

Below the station there are decrees for diversions of 2,871 second-feet from Boulder

Creek. 

Cooperation. Station maintained by the State engineer in cooperation with the

Central Colorado Power Co., by which the records are furnished.

324 SUBFACE WATER SUPPLY, 1911, PART VI.

SOUTH BOULDER CREEK NEAR ROLLINSVILLE, COLO.

Location. At highway bridge in sec. 35, T. 1 S., E. 73 W., 1 mile west of Eollinsville, in the Pike National Forest. The nearest important tributary, Jennie 

Creek, enters 3 miles above.

Records available. September 10, 1910, to December 31, 1911.

Drainage area. 39 square miles (measured from topographic sheets).

Gage. Vertical staff.

Channel. Fairly permanent.

Discharge measurements. Made from bridge during high water and by wading 

at ordinary stages.

Winter flow. Ice causes backwater during the winter months.

Diversions. There are no court decrees for diversions above the station, and therefore it is probable that the records represent the natural fun-off.

Accuracy. Conditions are favorable for fairly accurate results and the estimates of 

discharge should be reliable.

Cooperation. Station is maintained in cooperation with the United States Forest 

Service.

CACHE LA POTTDRE RIVER NEAR ELKHORN, COLO.

Location. At the lower bridge at Fry's ranch in the southern part of T. 9 N., R. 73

W., 7 miles southwest of Elkhorn post office. 

Records available. January 6, 1909, to December 31, 1911. 

Drainage area. 250 square miles (measured from King's Atlas). 

Gage. Chain gage; datum unchanged. . 

Channel. Fairly permanent. 

Discharge measurements. Made from bridge.

Winter flow. Ice causes backwater during the winter months and frequent measurements are made to determine the discharge. 

Diversions. There are no diversions from the Cache la Poudre above the station,

but the flow is increased by a diversion from Laramie River by the Skyline ditch

which has a court decree for 400 second-feet. 

Artificial control. The flow is controlled to a certain extent by the reservoir at

Chambers Lake, which is operated in the interest of irrigation diversions below. 

Accuracy. As the estimates of discharge are based on very frequent discharge

measurements they should be excellent. 

Cooperation. Station maintained in cooperation with private persons through Mr.

George B. McFadden, of Denver.

Discharge measurements of Cache la Poudre River near Elkhorn, Colo., in 1911.

LOUP RIVER AT COLUMBUS, NEBR.

Location. At highway bridge in sec. 25, T. 17 N., R.~ 1 W., at Columbus, Nebr. 

No tributaries between the station and the mouth of the river 3 miles below.

Records available. October 13, 1894, to December 31, 1911.

Drainage area. 13,500 square miles.

Gage. A chain gage installed at the highway bridge June 24, 1904, and set to read 

the same as the original vertical staff gage, which was located 1J miles above the 

bridge and was used from October 13, 1894, to that date. Owing to the slope of 

the river, however, the datum of the chain gage is 8.56 feet lower than that of the 

upper gage.
PLATT1 EIVEK BASIN. 337

Channel. Extremely shifting.

Discharge measurements. Made from highway bridge.

Winter flow. Ice causes backwater during the winter months and observations are 

discontinued.

Diversions. Prior to September 1, 1912, there were approved diversions of 1,764 

second-feet for irrigation and 4,700 second-feet for power from Loup River above 

the station. There were also approved diversions of 2,046 second-feet for irrigation and 3,130 second-feet for power, from tributaries entering above.

Accuracy. The extremely shifting channel makes it impossible to make estimates 

of daily discharge without almost weekly measurements, as the gage heights 

afford only an approximate indication of the flow.

Cooperation. During 1911 the station was maintained in cooperation with the State 

'engineer, by whom the field data were furnished.

KANSAS KIVEK BASIN. 

REPUBLIC ANplIVER AT BOSTWICK, NEBR.

Location. At highway bridge about 1 mile southwest of Bostwick, on the line 

between sees. 22 and 23 in T. 1 N., E. 8 W. Nearest tributary a small intermittent stream which enters a short distance below.

Records available. June 6, 1904, to December 31, 1911. From June 20, 1896, to 

November 30, 1903, a station was maintained at Superior, 10 miles downstream. 

As there are no important tributaries nor diversions between, the records at the 

two points are very nearly comparable.
340 SUEPACE WATEE SUPPLY, 1911, PAET VI.

Drainage area. 23,300 square miles.

Gage. Chain gage; datum unchanged.

Channel. Shifting at intervals.

Discharge measurements. Made from bridge.

Winter flow. Ice causes backwater during the winter months and during that 

period the observations are discontinued.

Diversions. Prior to September 1, 1912, there were approved diversions of 862 

second-feet for irrigation and 150 second-feet for power from Republican River 

above the Bostwick station.

Accuracy. During 1911 the channel did not shift to any great extent and the estimates of discharge should be reliable.

Cooperation. During 1911 this station was maintained in cooperation with the 

State engineer, by whom the field data were furnished.

LITTLE BLUE RIVER NEAR FAIRBTTRY, NEBR.

Location. At highway bridge in sec..26, T. 2 N., R. 2 E., 1J miles south of Fairbury. Nearest tributary a small stream entering half a mile above.

Records available. May 23, 1908, to December 31, 1911.

Drainage area. Not measured.

Gage. Chain gage; datum unchanged.

Channel. Shifting.

Discharge measurements. Made from bridge.

Winter flow. Ice causes backwater for only a short time during the winter monthsArtificial control. The dam of the Fairbury Roller Mills, located 2 miles above, 

may control the flow to a certain extent during the low-water season, causing a 

daily fluctuation. The gage is read once each day.

Diversions. Prior to September 1, 1912, there were approved diversions of 180 

second-feet for power from the Little Blue above Fairbury. There were none 

below.

Accuracy. Estimates have been made by indirect method for shifting channels, and 

can be considered only fair.

Cooperation. Station maintained in cooperation with the State engineer, by whom 

the field data are furnished.

MISCELLANEOUS MEASUREMENTS. 349

The following measurements of streams and ditches along North 

Platte River from the Wyoming State line to Kearney, Nebr., were 

made by R. H. Fletcher from September 15 to October 12, 1911. 

The capacity of the ditches was determined by Kutter's formulas, 

values of N=0.020 to 0.030, values of 8=0.0005 to 0.002. For 

ditches that were dry the value of S was determined by levels taken 

to high-water marks in ditches.
