SURFACE WATER , SUPPLY OF THE MISSOURI RIVER

BASIN, 1912,

By W. A. LAMB, ROBERT FOLLANSBEE, and H. D. PADGETT.

AUTHORIZATION AND SCOPE OF WORK.

This volume is one of a series of 12 reports presenting results of 

measurements of flow made on certain streams in the United States 

during the calendar year 1912.

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 

1895................................................... $12,500

1896................................................... 20, 000

1897 to 1900,inclusive................................... 50,000

1901 to 1902,inclusive................................... 100,000

1903 to 1906,inclusive................................... 200,000

1907................................................... 150,000

1908 to 1910,inclusive................................... 100,000

1911 to 1913, inclusive...................................' 150,000

In the execution of this work many private and State organizations 

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

made in connection with the description of each station affected; 

cooperation of the second kind is acknowledged on page 18.

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

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

10 SURFACE WATER SUPPLY, 1912, PART VI.

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

the Hawaiian Islands. During 1912 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 water supply papers from 

time to time.

PUBLICATIONS.

A report has been prepared for each calendar year embodying the 

stream-flow data collected during that year. An index to the reports 

containing stream-flow measurements prior to 1904 has been published as Water-Supply Paper 119. Circulars are also available giving 

complete lists of gaging stations maintained by the Survey to date 

and a list of the reports relating to the water supply of the country.

Prior to 1902 gage heights and discharge measurements were published in water-supply papers or bulletins and estimates of monthly 

discharge in annual reports; since 1902 both classes of data have been 

published in water-supply papers, and they are now being published 

in 12 parts, as shown in the following table.

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 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 ofthe factors given in the following table of equivalents.
14 SUEFACE WATER SUPPLY, 1912, PAET VI.

"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.

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
16 SURFACE WATER SUPPLY, 1912, PAKT VI.

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 height 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 

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 

height 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

PRICE CURRENT METERS.
ACCURACY AND EELIABILITY OF DATA. 17

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 defined 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." Plate I shows typical gaging stations; 

Plate II 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 fating 

tables used, and an accuracy column is inserted in the monthlydischarge 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.

Work in the Missouri River basin in Montana was carried on in 

cooperation with the State, authority having been granted in 1911 by 

the State legislature, which passed a bill appropriating funds to be 

expended on the work of gaging streams in accordance with paragraph 3, section 2244, of the Eevised 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 already made, if deemed reliable, 

may be adopted.

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

Carey Act projects.

In Wyoming also the stream gaging work was carried on in cooperation with the State represented by Mr. A. J. Parshall, State 

engineer. Mr. Parshall also arranged for cooperation with a number 

of individuals interested in the records at various stations.

Other cooperation in the Missouri River basin is acknowledged in 

connection with each station affected.

BEAVEEHEAD EIVEE AT BAEEATTS, MONT.

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

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

Records available. August 12, 1907, to December 31,1912. 

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.
SURFACE WATEB SUPPLY) 1912, PART VI.

Diversions. A large number of 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.

Accuracy. Results good.

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

the poet 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.

MISSOURI RIVER AT TOSTON, MONT.

Location. In SW. \ sec. 23, T. 5 N., R. 2 E., at the highway bridge crossing Missouri 

River at Toston, Mont., about 25 miles below the union of Gallatin, Jefferson, 

and Madison rivers.

Records available. April 5, 1910, to December 31, 1912.

Drainage area. Not measured.

Gage. Standard chain gage attached to downstream side of bridge.

Channel. Rocky and permanent.

Discharge measurements. Made from cable just above bridge.

Winter flow. Affected by ice.

Accuracy. Only one measurement made in 1912, but results may be considered 

good, owing to permanency of channel.

The only important tributary between the gaging station and the headwater forks 

is Sixteenmile Creek.

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

July 10, 1912: Gage height, 4.57 feet; discharge, 6,640 second-feet.
26 SURFACE WATER SUPPLY, 1912, PART VI.

Daily gage height, in feet, of Missouri River at Toston, Mont., for 1912.

MISSOUEI RIVER AT CASCADE, MONT.

Location. In sec. 35, T 18 N., R 1 W., 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, 1912.

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 ffow. Affected by ice.

Storage. The Montana Power Co. has a large reservoir near Helena, between the 

stations at Toston and Cascade.

Accuracy. Results good.

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.

Discharge measurements of Missouri River at Cascade, Mont., in 1912.

BOULDER RIVER BASIN. 

MUSKRAT GREEK NEAR BOULDER, MONT.

Location. In sec. 6, T. 6 N., R. 3 W., 1,000 feet above Boulder Nursery, near Boulder,

Mont.

Records available. April 27 to December 31,1912. 

Drainage area. Not measured. 

Gage. Staff gage fastened to a flume above a weir. Gage heights give the head on

the weir.

Channel. Flume. 

Discharge measurements. The flow of the stream is measured by a weir, sharp

crested and with end contractions. The weir is 4.85 feet long. The gage is

located 2.5 feet upstream from the crest. The daily discharge was obtained be

use of Francis's formula for weir end contractions. The velocity of approach

is about 1 foot per second at a gage height of 0.3 foot. 

Winter flow. Affected by ice. 

Artificial control. There is no regulation or diversion above the station; the flow

of the stream is used for irrigation. 

Accuracy. Results should be very good.

Daily gage height, in feet, of Muskrat Creek near Boulder, Mont., far 1912.

GAXLATIN RIVEB BASIN. 

WEST GALLATIN RIVER NEAR SALESVILLE, MONT.

Location. On highway bridge 4 miles above Salesville, Mont., just below mouth of 

canyon. Above the station Spanish Cre,ek is the most important tributary.

Records available.^July 18,1895, to December 31,1905; August 9,1910, to December 31, 1912.

Drainage area. 860 square miles.

Gage. Standard chain, boxed and fastened near middle of bridge on upstream side; 

datum unchanged.

Channel. Bed of stream is of gravel and small bowlders, and will not shift.

Discharge measurements. Made from the lower side of the highway bridge.

Diversions. Irrigation is practiced extensively on this stream, and practically the 

entire low-water flow of the river is appropriated.

Accuracy. Results uncertain, as no open-water measurements were made during 

the year.

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

March 1, 1912: Gage height, 2.92 feet (ice present); discharge, 245 second-feet.

Daily gage height, in feet, of West Gallatin River near Saleaville, Mont., for 1912.

CROW CREEK BASIN.

CEOW CEEEK NEAE TOWNSEND, MONT.

Location. In the SE. \ sec. 5, T. 6 N., E. 1 W., about one-half mile from Eagle 

Creek ranger station on Eagle Creek, 1,000 feet above the mouth of Eagle Creek 

and 150 feet below the crossing.

Records available. Gage heights January 5, 1912 to December 31, 1912. A gaging 

station was established by the United States Geological Survey on this creek 

about 5 miles below this one April 1, 1901. There have never been any gage 

readings at the old station. The United States Geological Survey and many 

private companies have made miscellaneous measurements on this creek.

Drainage area. 33 square miles.

Gage. Vertical staff.

Channel. Gravel, irregular and possibly shifting.

Discharge measurements. Made by wading or from the bridge.

Winter flow. Seriously affected by ice.

Diversion. Above this point water is used for placer mining. Below, the entire 

normal flow is used for irrigation on the land adjoining the Missouri River and for 

placer work along this creek.

Artificial control. None.

Data inadequate for estimates of discharge.

The following discharge measurement was made by B. E. Jones:

January 5, 1912: Gage height, 1.25 feet (ice present); discharge, 6.8 second-feet.

Daily gage height, infect, of Crow Creek near Townsend, Mont., for 191t.

PRICKLY PEAR CREEK AT EAST HELENA, MONT.

Location. IB NE. J sec. 36, T. 10 N., B. 3 E., at the point where the Northern Pacific 

Bailway crosses the stream at East Helena, Mont. The only important tributaries entering Prickly Pear Creek above the station are McCMlan and Lump 

Gulch creeks; Tenmile and Silver creeks come in below.

Records available.-^July 18, 1908, to December 31, 1912.

Drainage Area. Not measured.

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

unchanged.

Channel. Bocky, 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 fpr 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 CLANCT, MONT.

Location. In sec. 4, T. 8 N., B. 3 W., at the ranch of Charles Zastrow, 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, 1912.

Drainage area. Not measured.

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 r>reviously used. All gage heights for 1910 were reduced to new datum.

Channel. Sandy, likely to be blocked by drift, and shifting.

Discharge measurements. Made by wading.

Winter flow. Affected by ice.

Diversions. The water in Lump Gulch Creek has been extensively used for piacer 

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.

TENMILE CKEEK NEAR HELENA, MONT.

Location. In SW. i SE. i sec. 22 T. 10 N., R. 4 W., opposite the Broadwater Hotel

near Helena, Mont.

Records available. July 8, 1908, to December 31, 1912. 

Drainage area. Not measured. 

Gage. Staff on right bank; datum unchanged. 

Channel. Shifts somewhat during flood stages. 

Discharge measurements. Made by wading. 

Winter flow. Affected by ice. 

Diversions. Part of the water supply for the city of Helena is taken from Tenmile

Creek above the station. Two irrigation ditches also take water from the creek

above the gage. The entire low-water flow is appropriated and used before it

reaches the mouth of the creek. 

Accuracy. At low and medium stages conditions favor accurate determination of

discharge.

NOTE. There was a considerable shift in the channel some time in the spring but not enough measurements were made to properly define it. For this reason no estimates have been made for the period previous to July 1. Daily discharge after July 1, was determmed from a feirly well-defined rating curve, 

based on one measurement in 1912 and two in 1913.

SUN RIVER BASIN. 

ADJUDICATED WATER HIGHTS.

Practically the entire unappropriated flow of Sun River and its 

tributaries has been filed on by the United States Reclamation 

Service for the irrigation of 276,000 acres of land on the Sun River 

project. Most of this water will be obtained from the storage of 

flood waters.

NORTH FORK OF NORTH FORK OF SUN RIVER NEAR AUGUSTA, MONT.

Location. In sec. 22, T. 22 N., R. 10 W., at Warm Springs, about 28 miles northwest 

of Augusta.

Records available. May 27, 1911, to September 30, 1912.

Drainage area. Not measured.

Gage. The gage consists of two staffs. The low-water gage is nailed to a post driven 

into the bed of the stream on the left bank. The high-water gage is nailed to a 

post on top of the bank. The low-water gage reads to 93.00 feet.

Channel. Practically permanent.

Discharge measurements. At high stages measurements are made from a cable

and at low stages by wading near the gage. 

-Winter flow. Affected by ice.

Diversions. There are no diversions or artificial control above this station.

Accuracy. Conditions for obtaining accurate discharge data are excellent, but results for 1911 are rather uncertain owing to lack of discharge measurements.

SUN RIVER AT FORT SHAW, MONT.

Location. In SW. i sec. 1, T. 20 N., R. 2 W., at Port Shaw, Mont.

Records available. May 16, 1912, to December 31, 1912. Previous to 1912 practically the same data were obtained on Sun River at Sun River.

Drainage area. Not measured.

Gage. A standard chain gage fastened to the footbridge near the right bank.

Channel. Permanent.

Discharge measurements. At high and medium stages measurements are made 

from the footbridge at the gage and at low stages by wading.

Winter flow. Affected by ice.

Diversions. There are adjudicated rights for diverting 248 second-feet from Sun 

River direct and 664 second-feet from tributaries above this station. In addition 

to this the Port Shaw United States Reclamation Service canal takes out about 

200 second-feet during the irrigation season.

Accuracy. Conditions for obtaining accurate discharge data are excellent, but the 

results for 1912 are only fair, due to errors in the gage.

SUN RIVER BASIN. 57

SUN RIVER AT SUN RIVER, MONT.

Location. In the NW. J NE. i sec. 34, T. 21N., B. 1W., 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 31,1912.

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. The Sun River canal, with an adjudicated water right of 63 secondfeet, takes out between this station and the one at Fort Shaw. (See station 

description for Sun River at Fort Shaw.)

Accuracy. Conditions at the measuring section have been very poor since the high 

water of 1907; at low stages good measurements can be made.

SOUTH FORK OF NORTH FORK OF SUN RIVER NEAR AUGUSTA, MONT.

Location. In sec. 27, T. 22 N., R. 10 W., at Warm Springs, about 28 miles northwest

of Augusta.

Records available. May 27, 1911, to September 30, 1912. 

Drainage area. Not measured. 

Gage. The gage is a staff nailed to a post about 10 feet out in the stream. It is

difficult to read accurately in high water on account of wave action. There is

also a high-water section reading from 5.00 to 10.00 feet and nailed to a tree on

the bank, but the water has never reached this stage. 

Channel. Rocky and practically permanent.
SUN KIVER BASIN. 59

Discharge measurements. Measurements are made from a cable at high and

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

Winter flow. Affected by ice.

Diversions. No diversions or storage above this station. 

Accuracy. Conditions for obtaining accurate discharge data are excellent.

Location. In the NE. J sec. 27, T. 27 N., R. 7 W., at the Clark Co. ranch, just below 

the mouth of Little Willow Creek, and about 7 miles northwest of Augusta.

Records available. June 8,1905, to May 14, 1911, and April 1, 1912, to December 

31,1912.

Drainage area. Not measured.

Grage. A standard chain on right bank near observer's house; datum unchanged.

Channel. Permanent.

Winter flow. No ice forms at this station, as a large spring enters the creek just above 

the gage.

Diversions. The adjudicated water rights above this station amount to 36.2 secondfeet from Willow Creek proper and 42.26 second-feet from tributaries. The 

United States Reclamation Service has an old right of 2.1 second-feet and also has 

filed on the total flow of the creek, subject to the above prior appropriations. No 

water is diverted from Willow Creek proper below the station, the amount used 

by the United States Reclamation Service being diverted from Sun River below 

the mouth of Willow Creek.

Storage. Willow Creek dam, located about 2 miles below the station, provides a 

reservoir with a capacity of 84,320 acre-feet for use on the Fort Shaw unit of Sun 

River project.

Accuracy. Conditions for obtaining accurate discharge data are excellent.

SOUTH FORK OF SUN RIVER AT AUGUSTA, MONT.

Location. In sec. 17, T. 20 N., R. 6 W., at the highway bridge on the road from

Augusta to Craig, Mont., about half a mile from Augusta. 

Records available. December 2, 1904, to December 31, 1912, except during frozen

periods.

Drainage area. Not measured. 

Gage. The original gage was spiked to the cribwork of the right abutment on the

downstream side of the bridge; a new gage was installed April 17, 1907, at a

different datum and was used during 1907 and 1908; records for 1909-1912 are

referred to the old gage. 

Channel. Shifting.
SUN BIVEB BASIN. 65

Discharge measurements. High-stage measurements are made from the bridge 

at the gage. Low-stage measurements are made by wading.

Winter flow. Affected by ice.

Diversions. Water is diverted to irrigate the valley lands both above and below the 

station. During dry seasons the entire summer flow is utilized. Adjudicated 

water rights above the station amount to 70.16 second-feet from South Fork of 

Sun River proper and 196.68 second-feet from tributaries. Below the station there 

are adjudicated rights amounting to 50.70 second-feet, all from South Fork of 

Sun River direct.

Accuracy. Results good.

FORD CREEK NEAR AUGUSTA, MONT.

Location. In the SE. £ sec. 31, T. 20 N., R. 8 W., at the ranch of Joseph Ford, 

16 miles west of Augusta, Mont. Ford Creek has no tributary.

Records available. April 11, 1906, to December 31, 1912, except during frozen 

periods.

Drainage area. 18 square miles.

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

Channel. Shifting; current swift.
SUN MVER BASIN. 67

Discharge measurements. Made by wading.

Winter flow. Little affected by ice.

Diversions. One irrigation ditch with an adjudicated right of 37.50 second-feet and 

an ordinary flow of about 5.0 second-feet diverts water from the creek above 

the gage. The total adjudicated rights on Ford Creek prior to the United States 

Reclamation Service filings amount to 46.40 second-feet. The Reclamation 

Service has filed on the total unappropriated flow of the creek.

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

are necessary to properly define the rating curve.

Location. In the SW. \ sec. 8, T. 20 N., R. 3 W., where the county road crosses the 

canal, about 6 miles above Simms, and 8J miles along the canal, below the headworks of the canal.

Records available. June 9, 1912, to August 17, 1912.

Gage. A vertical staff nailed to the bridge near the center of the canal.

Channel. Shifts slightly.

Discharge measurements. Measurements are made by wading near the gage.

Winter flow. None.

Diversions. During 1912 no water was taken from the canal for use above this station, 

the losses being due to leakage.

Accuracy. The results obtained should be fairly good.

STOST RIVER CANAL AT VATTGHN, MONT.

Location. In the SW. i sec. 13, T. 21 N., R. 1 E., at Vaughn. The station is just

above the point at which Sun Biver canal empties into Muddy Creek. 

Records available. July 1,1912, to August 31,1912. 

Gage. A vertical staff driven into the bed of the canal near the left bank. 

Channel. Permanent.
74 SURFACE WATER1 SUPPLY, 1912, PART VI.

Discharge measurements. Made by wading near the gage.

Winter flow. None.

Diversions. All water used is diverted above this station, the results here showing 

the amount of water wasted.

Accuracy. Conditions for obtaining accurate discharge data are excellent. The 

results for 1912, however, are only fair, as there were not enough discharge measurements to accurately define a rating curve.

MARIAS RIVER BASIN. 

MARIAS RIVER NEAR SHELBY, MONT.

Location. In sec. 20, T. 31 N., R. 2 W., 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; 1912. 

Drainage area. 2,610 square miles.
MAEIAS BIVER BASIN. 75

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.

Cooperation. Several measurements were furnished by the engineers of the ValierMontana Land & Water Co.

Accuracy. Results good.

TWO MEDICINE RIVER AT FAMILY, MONT.

Location. In the NE. J NE. J 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, 1912.

Drainage area. 368 square miles.

Gage. Standard chain on the left bank of the stream directly back of the Mission 

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

Channel. Gravel.
MAEIAS EIVEE BASIN. 77

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. i sec. 19, T. 31 N., R. 8 W., near the road crossing, 4 miles

east of Family, Mont.

Records available. April 20, 1907, to December 31, 1912. 

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 good.

OUT BANK GREEK AT CUT BANK, MONT.

Location. In the SW. £ SW. J sec. 1, T. 33 N., R. 6 W., half a mile west of Cut

Bank, at the Great Northern Railway bridge, 12 miles above the mouth of Two

Medicine River.

Records available. August 4, 1905, to December 31, 1912. 

Drainage area. 971 square miles. 

Gage. Original gage was an overhanging chain gage on the left bank. On August 31,

1911, a staff gage was installed at a new section 200 yards farther upstream and

has since been read. 

Channel. Gravel; shifts in flood. 

Discharge measurements. At high stages made from a cable 300 yards below

the gage; low-stage measurements made by wading. 

Winter flow. Affected by ice. 

Diversions. The intake of the Great Northern Railway's pumping station is located

50 feet below the gage; the average quantity pumped is about 14,000 gallons an

hour for 18 hours a day, equivalent to a continuous flow of 0.4 second-foot. 

Accuracy. Results as a whole are good.

BIRCH CREEK NEAR DUPUYER, 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, 1912.

Drainage area. 155 square miles.

G-age. 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. A Bristol automatic gage was installed April 1, 1911, but the chain gage is still read daily.

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.

Cooperation. Gage heights and discharge measurements were furnished by the 

engineers of the Valier-Montana Land & Water Co.

Accuracy. Owing to frequency of measurement during 1912 the results are considered good.

NOTE. The record obtained from the Bristol automatic gage was more or less unsatisfactory on account 

of the well silting up. The daily gage heights are based largely upon the daily readings of the chain gage. 

The relation of gage height to discharge was affected by ice Jan. l to Mar. 31 and Nov. 24 to Dec. 31. 

Jan. 4-12 the stream was frozen solid at the gage.

NOTE. The above drainage area was determined by the engineers of the Valier Carey Project, and 

supersedes the value 155 previously used.

DUPUYER CREEK AT DUPUYER, MONT.

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

town of Dupuyer, Mont.

Becords available. April 15, 1908, to December 31, 1912.

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 side. A new gage was installed April 25, 1910, at the same 

site as the original datum, but owing to changes in the channel the gage records 

for 1910-1912 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 but results for 1912 are considered 

good.

Cooperation. Gage heights and discharge measurements were furnished by the 

engineers of the Valier-Montana Land & Water Co.

DUPUYER CREEK NEAR VALIER, MONT.

Location. In NE. J NW. J sec. 33, T. 29 N., R. 6 W., about 11 miles northwest of 

Valier. It is about 1,000 feet above a large diversion dam at the head of the canal 

from Dupuyer Creek to Lake Francis reservoir. The Birch Creek canal enters 

Dupuyer Creek below the gaging station and above the diversion dam.

Becords available. July 17 to December 31, 1912.

Drainage area. Not measured.

Gage. A standard chain gage and a Bristol automatic at the same section.

Channel. Shifts slightly.

Discharge measurements. Made from a cable at high stages and by wading at 

medium and low stages.

Winter now. Affected by ice.

Diversions. There are numerous water appropriations recorded, but many of the 

rights have never been used.

Accuracy. Conditions for obtaining accurate discharge data are good.

Cooperation. Gage heights and most of the discharge measurements were furnished 

by the engineers of the Valier-Montana Land & Water Co.

TETON RIVER AT STRABANE, 1 MONT. .

Location. In the SE. \ NE. \ sec. 35, T. 25 N., R. 7 W., on the highway bridge half 

a mile north of Peeble's ranch, 16 miles above Chouteau, Mont., at Strabane poet. 

office.

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

to December 31, 1912.

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 1£ miles upstream 

to Mr. Bjomstad'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 half a mile downstream from the old gage. The gage is a standard chain 

fastened to the upstream side of the bridge near the center of the river.

Channel. Shifts at high stages; current swift. There are several channels at both 

low and high stages, but the main channel carries about 80 per cent of the flow 

at high stages and 85 per cent at low stages. The results show the total flow of 

all the channels.

Discharge measurements. At flood stages made from the bridge at 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 at Teton River in the reservoir about 5 miles north of the gaging section. 

The capacity of the reservoir ia 106,700 acre-feet and it can be inreased to 210,000 

acre-feet by raising the top of the dam 20 feet. The reservoir will serve 55,400 

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.

DEEP CREEK AT FRAZIER's RANCH, NEAR CHOUTEAU, MONT.

Location. Near the center of sec. 26, T. 23 N., R. 8 W., about 22 miles southwest of

Chouteau and above the mouth of Barrett Creek. 

Records available. May 25, 1912, to November 15, 1912. 

Drainage area. Not measured. 

Gage. An overhanging chain gage. 

Discharge measurements. Made by wading at a ford about 1,000 feet above the

Channel. The channel is rocky and nonshifting. 

Winter flo-w. Affected by ice. 

Diversions. None above the station.

Accuracy. Conditions for obtaining accurate discharge data are good, but the rating 

curve for 1912 is only fairly well defined by the measurements so far made.

WILLOW CREEK NEAR CHOU1EAU, MONT.

Location. In sec. 14, T. 23 N., R. 6 W., at McPhee's ranch, 12 miles southwest of

Chouteau, Mont.

Records available. April 2, 1912, to December 31, 1912. 

Drainage area. Not measured. 

Gage. Staff gage on left bank. Low-water section reads to 5.00 feet; high-water

section reads 5.00 to 9.00 feet. 

Channel. Fairly permanent. 

Discharge measurements. Made by wading at the gage except in extreme high

water, when they may be made from a bridge half a mile below the gage. 

Winter flow. Affected by iee. Probably little flow. 

Diversions. There are several diversions above the station, mostly to water hay

MUSSELSHELL RIVER BASIN. 

NORTH FORK OF MUSSELSHELL RIVER NEAR MARTINSDALE, 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, 1912.

Drainage area. Not measured.

Gage. Chain on 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 flood water of the North Fork, the normal 

flow of 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.

MUSSELSHELL EIVER AT HARLOWTON, MONT.

Location. In sec. 26, T. 8 N., R. 15 E., at the highway bridge 1 mile south of 

Harlowton.

Records available. July 11,1907, to December 31,1912. A station was maintained 

at Shawmut from August 12, 1902, to June 30, 1907.

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.
104 SURFACE WATEE SUPPLY, 1912, PART VI.

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.

SOUTH FORK OF MUSSELSHELL RIVER NEAR MARTINSDALE, MONT.

Location. In the S. £ sec. 12, T. 8 N., R. 11 E., near the public highway, 1J miles

northeast of Martinsdale, near the blacksmith shop of the Martinsdale Sheep Co.,

at a point about 1£ miles above the original site, which was near the ranch of

M. J. Settle. 

Records available. June 19, 1907, to April 28, 1908 (old station); April 28, 1908,

to December 31, 1912. 

Drainage area. Not measured. 

Gage. Staff nailed to tree on the right bank; datum unchanged. The datum of this

gage bears no determined relation to the datum of the gage at the original station. 

Channel. Bed of stream is chiefly gravel and is clean and nonshifting. 

Discharge measurements. Made by wading near the gage or from a bridge 150

feet below.

Winter flow. Affected by ice. 

Diversions. Many small ditches take water from the creek and during the irrigating

season all the water is diverted. 

Accuracy. Open season records good.

MILK RIVER AT HAVRE, MONT.

Location. In SE. i SE. i 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, 1912.

Drainage area. Not accurately known.

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, Canada, 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 other important irrigation rights above Havre, but farther dowjistream 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.

MILK RIVER AT MALTA, MONT.

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

Malta, Mont.

Records available. July 31, 1902, to December 31, 1912.

Drainage area. Not accurately known.

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 now. 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 constructed a diversion dam at Dodson, about 17 miles 

above the station, which will eventually divert water for the irrigation of about 

108,000 acres of land in Milk River valley. East of Malta there are nearing completion two canals, one on each side, the combined discharge being 1,000 secondfeet.

well defined from 14 to 30 feet. Discharge, Apr. 5-17, estimated from the high-water mark, which was 

referred to the gage datum by leveling the date of the highest water having been observed by the hydrographer; also from a current meter measurement at Vandalia, 6 mOes below Hinsdale on Apr. 10. Dairy 

discharge estimated Aug. 9-12,14-20, and 22-29. Discharge estimated Nov. 17-30 at 250 second-feet.

NOETH FORK OF MILK EIVEE NEAR CHINOOK, MONT.

Location. In sec. 3, T. 33 N., R. 19 E., at a point about 4J 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, 1912.

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.

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,1 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 13, 1912.

Drainage area. Not measured.

Gage. Overhanging chain. 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, 2J 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 flow. 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 willows in the channel 

makes the construction of a permanent rating curve difficult.

BEAVEE CREEK OVERFLOW NEAR BOWDOIN, MONT.

Location. In the SW. J sec. 17, T. 30 N., R. 32 E., at John Turmell's ranch, 14 miles

from Malta, Mont. 

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

31, 1910; March 20, 1911, to November 9, 1912. The gage was washed out and

bench marks destroyed in the spring of 1912. Gage heights for 1912 are referred

to a new datum. 

Gage. Staff. 

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.

HOCK CREEK NEAR HINSDALE, MONT.

Location. In sec. 10, T. 31 N., R. 36 E., at Ottenstror's ranch, about 2 miles below the head gates of Rock Creek canal and 6 miles northeast of Hinsdale.

Records available. April 19, 1912, to December 31, 1912. From July 5, 1905, to 

December 31, 1907, data were obtained at a station 2 miles upstream, just below 

the diversion dam of the Rock Creek canal. The flow at these two points is 

practically the same.

Drainage area. Not measured.

Gage. Overhanging chain gage on the left bank.

Channel. Shifts slightly at high water.

Discharge measurements. Made by wading one-fourth mile below the gage at 

low and medium stages and from a bridge 2 miles below at high stages.

Winter flow. Affected by ice.

Diversions. There is no storage, but the normal summer flow is appropriated and 

used during the irrigation season.

Accuracy. Conditions for obtaining accurate discharge data are good.

a The maximum discharge during the flood of Apr. 1 to 10 was estimated from a cross section and slope 

of the stream at the highway bridge below the station, using Kutter's formula with "n" equal to ".030" 

for the main stream and ".040" for the overflow. This estimate was checked by applying the high-water 

mark at the station to the station-rating curve. Although no high-water measurements have been made, 

the general direction of the curve should give fair results. The discharge obtained was 10,000 second-feet. 

The old observer, Mr. Hulbert, estimated the flood of 1906 to have been 1 foot higher at the old station on 

Rock Creek than that of 1912.

FLOODS IN MILK RIVER BASIN, APRIL, 1912. 

CAUSES.

During the first 20 days of April, 1912, the streams in the Milk 

River basin were at an exceptionally high stage, which from Malta 

to the mouth of the river amounted to flood. Unlike previous floods 

of which there is record, this flood was caused wholly by the rapid 

melting of snow during a period of warm weather that came so 

early that the winter snows still lay on ground saturated by the 

excessive rainfall in the autumn of 1911 and probably frozen to a 

considerable depth; so that the whole run-off had to be carried by 

the surface channels. The precipitation during the winter was not 

heavy,'the total for December, 1911, and January, February, and 

March, 1912, amounting to 1.71 inches at Havre, 1.19 inches at Malta, 

and for January, February, and March, 1912, to 1.13 inches at Glasgow; but 1.23 inches of rain fell at Havre on April 11, 12, and 13, 

1.25 inches fell at Malta from April 11 to 14, and 0.90 inch at Glasgow 

on April 13. The rise in the streams caused by this rainfall was not, 

however, proportional to its amount. Above Havre the run-off was 

not excessive, partly because of lack of large tributaries and partly 

because there was less snow or the snow was less evenly distributed. 

From Havre to Malta the water was very high but did little damage, 

the river in most places remaining within its banks. Below Malta 

the river overflowed its banks most of the way to its mouth, causing 

considerable damage and flooding several towns, notably Glasgow. 

Saco was flooded by the waters of Beaver Creek. From Hinsdale 

down the river rose about as high as during the flood of June, 1906, 

but sustained the stage much longer, the mean for April, 1912, at 

Malta being 5,540 second-feet, as compared with 4,150 second-feet 

for June, 1906.

The streams of the flooded area are fairly well covered by the regular stations of the Geological Survey, and several miscellaneous

The estimated maximum discharge for June, 1906, and April, 1912, 

of streams in the Milk River Valley, with the drainage area of some 

of them, is shown by the following table. The estimates for the flood 

of June, 1906, as published in Water-Supply Paper 208, are given for 

comparison.

An attempt has been made to give an accurate rating to the estimates for 1912. A similar rating could not well be made for those 

estimates of 1906, but it should be borne in mind that the latter were 

made largely by applying Kutter's formula to flood cross sections 

and surface slopes, and such estimates are liable to large errors due to 

variation in the value assumed for "n."

NOTE. The estimates of maximum discharge for the flood of June, 1906, outside of the stations on Milk 

River at Havre and Malta, are based largely on flood cross sections and surface slope and should not be 

used except in connection with other data.

These tables indicate fairly well the source of the flood, its cause, 

and, in connection with the flood of June, 1906, give a very good 

basis for estimating future floods of the same character.

DETAILS BY BASINS.

The flood can best be studied by dividing the basin into four parts, 

(1) above Havre, (2) from Havre to Malta, (3) from Malta to Hinsdale, and (4) below Hinsdale.

Above Havre the flood was small and its duration was short. The 

maximum discharge came on April 3, which is earlier than at any 

other point of which record is available, except possibly Beaver 

Creek. Probably most of the water at Havre came from Sage Creek, 

a large tributary that enters just above Havre.

If the area above the Canadian line is deducted from the drainage 

area at Havre only 1,250 square miles remains as the area actually 

affected by the flood, or nearly the same as the area drained by North 

Fork of Milk River. The mean flow of the North Fork of Milk River 

is 1,340 second-feet, to be compared with 1,440 second-feet of the 

Milk at Havre.

Between Havre and Malta several large creeks enter Milk River, 

the total tributary area between the two stations being 5,650 square
132 SURFACE WATER SUPPLY, 1912, PAST VI.

miles. The maximum discharge at Malta came on April 14, but the 

stage was practically constant from April 5 to April 14. That it did 

not go higher is probably due partly to storage and partly to the fact 

that the.creeks coming from the south, such as Peoples Creek, Snake 

Creek, and Clear Creek, reached their maximum flow about April 2 

or 3, as did also Beaver Creek, whereas West Fork, like North Fork, 

was probably highest about April 8. Considerable water was also 

stored "between Havre and Malta, as is shown by the flow at Malta 

during the latter part of the flood.

If the flow of West Fork of Milk River is assumed equal to that of 

North Fork in the period from April 12 to 20, inclusive, the drainage 

area being nearly the same, the run-off from about half of area between Havre and Malta is accounted for. The other half of the 

drainage lies south of the river and probably contributed very little 

to the run-off after April 12. The rate of run-off may therefore be 

estimated at one-half that of North Fork and West.Fork. This 

assumption gives a discharge at Malta for nine days of about 1,300 

second-feet due to storage. The fact that practically all of this 

amount was stored previous to April 5, the day on which the river 

reached flood stage, probably accounts for the small discharge from 

the area between Havre and Malta for the first four days of April.

The drainage area between Malta and Hinsdale is not much larger 

than that between Havre and Malta, but both the maximum and 

mean discharge for the flood are nearly twice as great, probably 

because of the larger quantity of snow on the area. In this stretch 

three large tributaries Beaver, Rock, and Frenchman creeks 

enter within a short distance, giving opportunity for regulating flow 

by natural storage in the river channel. Beaver Creek, which comes 

from the south, reached its maximum stage at Hinsdale about April 

6, and on April 7 had receded only 0.6 foot. The maximum discharge was estimated very roughly at 4,630 second-feet from a 

measurement of the main channel on April 7 and a cross-section of 

the overflow. After April 7 Beaver Creek fell rapidly. In considering the records of the station near Saco it should be remembered that 

the discharge at the mouth of the creek includes also the water 

carried by Beaver Creek overflow and Larb Creek.

Rock Creek, like Beaver Creek, probably reached its maximum 

flow about April 6, and remained high for some time.

Frenchman Creek reached its maximum stage about April 18, but 

must have had a large discharge on April 6. No information is 

available concerning the other creeks that enter between Malta and 

Hinsdale, but they were probably at maximum stage about April 6. 

A fairly good check on the estimates is obtained by adding the total 

flow of these creeks to that of Milk River at Malta for April 5, and 

comparing the sum with the flow at Hinsdale. If the maximum
MILK BIVEE BASIN. 133

flow of Rock Creek is assumed as 10,000 second-feet, Beaver Creek 

at Hinsdale at 4,600 second-feet, Frenchman Creek and Whitewater 

Creek at 3,000 second-feet each, the total is 20,600 second-feet. 

For Cottonwood Creek and Little Cottonwood Creek no data are 

available except the estimates for June, 1906, which appear high. 

The drainage area for these two creeks is small, so that if the discharge was very high it could not have lasted long, as the mean discharge of 5,000 second-feet may be assumed for these two creeks 

on April 6. Adding the flow at Malta on April 5 gives a total of 

34,500 second-feet to be accounted for at Hinsdale. The discharge 

at Hinsdale was 24,200 second-feet, leaving 10,000 second-feet to be 

accounted for by storage or deducted from the estimates. Milk 

River at Hinsdale rose from 9,000 second-feet on April 4 to 24,200 

second-feet on April 6, so that a large part of the total storage was 

consumed in two days. The amount of this storage can be estimated 

from the flow during the period of falling stage from April 14 to 21, 

inclusive. Assuming Rock Creek to have been discharging 4,000, 

3,000, 2,000, and 1,500 second-feet on April 14 to 17, estimating 

Frenchman Creek at 3,000 second-feet per day, taking Beaver Creek 

overflow at twice the flow of Beaver Creek for the three days for 

which gage heights are missing, and estimating the combined flow of 

the remaining tributaries, including Cottonwood, Whitewater, and 

Larb creeks at 2,000 second-feet per day, which is probably high, 

there still remains a total of 30,000 second-feet at Hinsdale coming 

from storage. As the upper end of the river, at Malta, was already at 

flood stage on April 5, it is probable that only about two-thirds of 

this storage was available. The loss of 10,000 second-feet on April 

5 and 6 is thus accounted for and makes a fairly good check on the 

estimates for the tributary creeks.

Data on which to base estimates of flow below Hinsdale are meager 

and are practically all presented in the table of maximum discharges. 

The tributary creeks are shorter than those in the sections above, 

anql the river id wide and winding, affording a large amount of 

storage.

FUTURE FLOODS.

The records of the flood of 1912, combined with those of the flood 

of June, 1906, afford a good basis for prediction of the effects of 

future floods. During April, 1912, the creeks to the south reached 

a flood stage a few days earlier than those from the north, and it 

appears reasonable to assume that this condition is normal to floods 

caused by melting snows. It also appears reasonable to assume that, 

although heavier rains than those of June, 1906, may occur, they 

will be sufficiently greater to cause a much larger flood. Floods 

due to rains usually find the river at a low stage and are regulated
134 SURFACE WATER SUPPLY, 1912, PART VI.

by storage in the river channel, but excessive rains similar to those 

of June, 1906, might occur with the river still at maximum stage, as 

from April 6 to 20, causing a second flood on top of the first. Even 

in this event a rise of a few feet would result only in additional 

storage through the long, winding course of the river, so that the 

maximum height would be only a few feet greater and the maximum 

discharge in proportion, and the river could probably carry the excess 

without very great damage. At Hinsdale, however, where three 

large tributaries enter within a distance so short that room for storage 

is lacking, the menace of damage from floods is more serious. Floods 

due to rainfall over the areas drained by these three tributaries, 

coming just after a flood similar to that of April, 1912, when the river 

was still near a maximum stage, would pile up the water in the 

neighborhood of Hinsdale, possibly doubling the discharge recorded 

at that point in April, 1912, but this excessive high water would 

not reach very far downstream before the increased storage would 

take the peak of the flood, and at Glasgow and below the rise would 

probably not greatly exceed that of the floods of 1906 and 1912, the 

high water simply lasting over a longer period. Such an excessive 

flood, however, though possible, is very unlikely, and probably 

would not occur more than once in a hundred years.

on Milk River and its tributaries made during the flood of April, 1912:

PRIVATE CANALS IN MILK KIVEK 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 

Hill and Blaine counties 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.

curve; June 16 to Aug. 13, by indirect method for shifting channels; Aug. 28 to Sept. 30, from a poorly 

defined -rating curve. Discharge interpolated Aug. 14-27 and 29-31. Practically no flow after Sept. 30. 

The flow in March is probably due to the high water in the river overflowing into the canal.

NOTE. Water was turned into the canal May 25 but no gage height observations were made until July 1. 

The mean flow from May 25 to June 24 inclusive is estimated at 40 second-feet per day.

The flashboards at the head of laterals below the gage were changed July 25. The gage height of the 

observer was made before this change was made, thus accounting for the difference between the observer's 

and hydrographer's readings.

The changes in gage height after July 25 are due to changes in the flashboards in the canal below the gage.

The canal was closed for the season on Aug. 9.

Daily discharge determined from a poorly denned rating curve.

Discharge estimated June 26 to 30 and July 26 to Aug. 9. Total for the period June 25 to Aug. 9 is 2,030 

acre-feet. Accuracy about "C."

FORT BELKNAP CANAL NEAR CHINOOK, MONT.

Location. In the SE. | sec. 20, T. 33 N., R. 18 E., at the highway bridge, about 

500 feet below the headgates of the canal, 8 miles west of Chinook.

Records available. June 21, 1903, to December 31, 1912.

Gages. The highwater of June, 1908, washed out both the bridge and the gage; a 

new gage was installed June 27,1908, at a different datum within a few feet of the 

site of the old gage; a new bridge was built about one-fourth mile upstream from 

the site of the old one.

Discharge measurements. Made by wading at a section about 300 feet below the

LITTLE PORCUPINE CREEK BASIN. 

LITTLE PORCUPINE CREEK AT FRAZER, MONT.

Location. In SE. | NE. J sec. 28, T. 27 N., R. 44 E., above the intake of the reservoir, about 1£ miles above the site of the station maintained from 1908 to 1910 

and about one-half mile north of Frazer.

Records available. July 13, 1908, to September 30, 1910, at the original station; 

April 14, 1911, to December 31, 1912, at present site.

Drainage area. Not measured.

Gage. Staff; and about 2 miles farther upstream than that originally used.

Channel. Shifting. On the date on which the station was reestablished in 1911 the 

channel was dry at the new gage but the stream was discharging 0.3 second-foot 

at the old gage, the water coming from springs near the gage.

Discharge measurements. Made by wading.

Accuracy. Results are only fair.

NOTE. Daily discharge determined from a well defined rating curve. Discharge interpolated for days 

for which gage heights are missing.

A measurement was made on Apr. 12, at a gage height of 8.05 at the old station at Obershaw's ranch and 

the discharge was found to be 3,380 second-feet. Using the old rating curve for Obershaw's in connection 

with this measurement and the maximum gage height of 12 feet at Obershaw's a maximum discharge of 

10,000 second-feet is obtained.

YELLOWSTONE EIVEE AT HUNTLEY, MONT.

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

1 mile below Huntley, Mont., 1 mile below Pryor Creek.

Records available. October 1, 1907, to December 31, 1912. A station was maintained May 10, 1906, to December 31, 1907, at Junction, Mont., where the flow 

is practically the same as at Huntley.
YELLOWSTOHE RIVER BASIN. 151

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 occurrence.

Diversions. 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 INTAKE, MONT.

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

Glendive, Mont.

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

1893 to 1903; August 1, 1903, to December 31, 1912, by United States Geological 

Survey. Records January 1 to December 31, 1912, from observations at the 

present station, which replaces the one formerly maintained at Glendive.
YELLOWSTONE RIVER BASIN. 153

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 raises 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.

Daily gage height, in feet, of Yellowstone River at Intake, Mont., for 1912.

NOTE. Gage heights after Oct. 18 are somewhat doubtful, owing to the fact that on April 21,1914, 

the gage was found to be reading 0.7 foot low. Hydrographs indicate that gage was reading correctly 

up to Oct. 18,1912, and that after that time it was probably in error. No correction has been made of 

observations in 1912.

SWEETGEASS CEEEK ABOVE MELVILLE, MONT.

Location. In the SW. J sec. 24, T. 5 N., R. 12 E., at C. 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.

Becords available. May 5, 1907, to December 31, 1912.

Drainage area. 69 square miles.

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'e ranch, just above the head of the canal owned by the

GlaBB-Lindeay Land Co. 

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

April 1,1909, to December 31,1912.
YBLLOWSTONE RIVER BASIN. 163

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

miles below the headgate 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.

WOODBINE CEEEK NEAE NYE, MONT.

Location. In the SE. J sec. 32, T. 5 S., E. 15 E., 7 miles south of Nye, Mont., 

approximately a quarter of a mile from the junction of this creek and the Stillwater 

River.

Records available. Two measurements in 1911, one in 1912, and scattering gage 

heights for 1912.

Gage. Sloping staff.

Channel. Large rocks; very rough.

Discharge measurements. Made by wading.

Winter flow. Affected by ice.

Diversion. None.

Data insufficient for estimates of discharge.

Measurements are made at this station to determine the amount of water available 

for power. In the first mile from its mouth the creek has a fall of 900 feet, and there 

is at present an application for development of its power.

The following discharge measurement was made by J. C. Beebe:

January 16, 1912: Gage height, 2.35 feet; discharge, 4.6 second-feet. Ice present 

in stream at gage.

Daily gage height, in feet, of Woodbine Creek near Nye, Mont., for 1912.

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 the mouth of Little Wind River.

Records available. May 15, 1911, to October 31, 1912. 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 and discharge measurements are made to determine the approximate flow.

Diversions. Prior to July 1,1912, there were adjudicated diversions of 34 second-feet 

from Wind River above the station and of 91 second-feet from tributaries entering 

above.

Accuracy. Although the channel shifted after the high water of 1912, sufficient 

discharge measurements have been obtained to make the estimates reliable.

HOESE CEEEK AT DUBOIS, WYO.

Loeation. At Dubois, in sec. 7, T. 41 N., R. 106 W., 100 yards above the mouth and

1£ miles below the entrance of Piney Creek. 

Records available. August 4, 1910, to June 30, 1912. 

Drainage area. Not measured. 

Gage. Vertical staff.
YELLOWSTONE EIVEE BASIN. 185

Channel. Data too meager to determine.

Discharge measurements. Made from bridge at the station during high water 

and by wading at ordinary stages.

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

discontinued. 

Diversions. Prior to July 1, 1912, there were adjudicated diversions of 14 secondfeet from Horse Creek above 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 WIND BIVER ABOVE ARAPAHOE, WTO.

Location. At railroad bridge in sec. 23, T. 1 S., K. 3 E., opposite the Indian subagency, one-fourth mile above Arapahoe and one-fourth mile above the mouth 

of Popo Agie River.

Becords available. May 14, 1911, to October 31, 1912. From May 11, 1906, to 

December 17, 1909, a station was maintained a short distance above the present 

one. The flow at the two points is comparable.

Drainage area. Not measured.

Gage. Chain gage reading approximately 1.6 feet higher than the gage at the former 

station.

Channel. Somewhat shifting after high water.

Discharge measurements. Made from railroad bridge.

Winter flow. Ice causes backwater during the winter months and discharge measurements are made to determine the approximate flow.

Diversions. Prior to July 1, 1912, there was an adjudicated diversion of 4.3 secondfeet from Little Wind Elver.

Accuracy. Although the channel shifted somewhat after the high water of 1912, 

sufficient discharge measurements have been made to make the estimates reliable.

LITTLE WIND RIVER BELOW ARAPAHOE, WYO.

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

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

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

Records available. May 11,1906, to November 27, 1909; May 14, 1911, to October 

31, 1912.

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. Shifting slightly from year to year.

Discharge measurements. Made from highway bridge.

Winter now. The river is frozen over during the winter months and discharge 

measurements are made to determine the approximate flow.

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 its tributaries.

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

this, and the estimates should be reliable.

« Estimated from two discharge measurements and climatologic data.

POPO AGIE EIVEK NEAR LANDEK, WYO.

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

station in sec. 24, T. 32 N., R. 101 W., about 6 miles southwest of Lander. The 

nearest tributary enters several miles below.

Records available. April 1, 19U, to June 30, 1912.

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 higher than the original gage. ' 

All readings have been referred to the latter gage.

Channel. Apparently permanent.

Discharge measurements. Made by wading.

Winter flow. Ice causes backwater during the winter months and the observations 

are discontinued.

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

from the Middle Fork prior to July 1,1912. Very nearly all of this water is diverted 

below the station.

Accuracy. Conditions are favorable for accurate results except that the discharge 

above 300 second-feet may be somewhat in error, owing to a lack of high-water 

measurements. Results for 1912 are somewhat uncertain, as no discharge measurements were made during 1912.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

Daily discharge, in second-feet, ofPopo Agie River near Lander, Wyo.,for 1911.

YELLOWSTONE RIVER BASIN. 189

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, 1911, to October 31, 1912.

Drainage area: Approximately 360 square miles.

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

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

datum, but 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 

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

Accuracy. Conditions are favorable for .accurate results and the estimates are considered reliable.

NOTE. Daily discharge determined as follows: Apr. 8 to Aug. 7 from a rating curve fairly well defined 

above and poorly defined below a discharge of 75 second-feet; Aug. 8 to Oct. 1, by shifting channel methods, 

and Oct. 2 to Oct. 31 from a rating curve fairly well defined for discharges from 115 to 170 second-feet. The 

change in the rating curve Aug. 8 to Oct. 1 was comparatively slight and parallel, so that the results obtained by shifting channel method are fairly good.

YELLOWSTONE EIVEE BASIN. 201

SHOSHONE RIVER AT OORBETT DAM, WYO.

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

8 miles below Cody, Wyo.

Becords available. April 20,1908, to December 31, 1912.

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 gates as submerged orifices. The following formula 

for discharges over the crest was developed by W. A. Lamb from measurements 

at Cody, Wyo.: Q=3.50 bh1 - 58 . 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.

Diversions and storage. Little water is diverted above this station, but the Shoshone Reservoir with a capacity of 456,000 acre-feet controls the flow.

Cooperation. Gage height and discharge into Corbett tunnel furnished by the 

United States Reclamation Service.

Accuracy. Results should be fair.

Daily gage height, in feet, of Shoshone River at Corbett dam, Wyo., for 1912.

LITTLE BIGHORN RIVER NEAR CROW AGENCY, MONT.

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

Crow Agency, Mont., in W. J sec. 18, T. 3 S., R. 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, 1912.

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.

Accuracy. Results good.

TONGUE RIVER BASIN. 

TONGUE RIVER NEAR DAYTON, WYO.

Location. At the edge of the Bighorn National Forest, in the NE. \ sec. 11, T. 56 N.,

R. 87 W., 3 miles southwest of Dayton, 3f miles below the mouth of Sheep Creek. 

Records available. October 24, 1911, to May 25, 1912. From May 3 to October 31,

1903, a station was maintained at Dayton.

Drainage area. 214 square miles (measured from topographic sheets). 

Gage. Vertical staff. 

Channel. Apparently permanent. 

Discharge measurements. Made from highway bridge 2 miles below station

during high water and by wading at the gage at ordinary stages. 

Winter flow. Ice causes some backwater during the winter months. 

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.

GOOSE CREEK AT SHERIDAN, WYO.

Location. Above the mouth of Little Goose Creek, at the footbridge in city park at

Sheridan, Wyo. 

Records available. From April 10, 1896, to August 1, 1897, and from May 14, 1911,

to October 31, 1912. 

Drainage area. Not measured. 

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

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

Badge, below the mouth of Little Goose Creek.
TONGUE RIVER BASIN. 215

Channel. Slightly shifting; 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 ancl 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 Goose Creek drainage 

basin above the mouth of Little Goose Creek.

Accuracy. Results fair.

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 Big Goose Creek at Sheridan, Wyo.

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

1912.

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.
TONGUE EIVEB BASIN. 217

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

Discharge measurements. Made from the downstream tside 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 obtained are good.

CLEAR CREEK NEAR BUFFALO, WYO.

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

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

junction of the North and South Forks.

Records available. October 22, 1911, to June 28, 1912. 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.
POWDER EIVEE BASIN. 221

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. Prior to July 1,1912, there were adjudicated diversions from Clear Creek of 333 second-feet below the station.

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.

LITTLE MISSOURI RIVER BASIN. 

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.

Records available. April 30,1904, to November 30,1906; June 18,1911, to December 31, 1912. Estimates of daily discharge for 1912 can not be made until sufficient high-water measurements are obtained to define a rating curve.

Drainage area. About 780 square miles.

Gage. An overhanging chain gage on the right bank. During 1911 a vertical staff 

gage 150 feet farther downstream on the left bank was used. The chain-gage 

datum is 0.08 foot lower than that of the staff gage. They also have different 

points of control.

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 

from a cable.

Winter now. Affected by ice.

« The mean of five float velocities using a coefficient of .85 was 2.34 feet per second, while the velocity 

computed by Kutter's formula was 2.18 feet per second. The mean of these was used to compute discharge, 

using the cross section of Oct. 30, 1912. The Little Missouri at Alzada, above Thompson Czeek, carried . 

410 second-feet, as measured by current meter on April 17.

HEART RIVER BASIN. 

HEART RIVER NEAR RICHARDTON, 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 December 31, 1912.

Drainage area. 1,250 square miles.

Gage. Overhanging chain gage installed September 4, 1911, 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. This overhanging chain gage was destroyed by the flood 

of March 27,1912, and on April 1 a temporary staff gage was installed at observer's 

house and was used until May 6, when a new chain gage was installed. All gage 

readings for 1912 have been referred to the chain gage installed on May 6.

Channel. Not permanent.

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

low stages, by wading.

Winter flow. Affected by ice.

Accuracy. Results fair.

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 9,1911, to December 31, 1912.

Drainage area. 3,670 square miles.

Gage. Standard chain on projecting cantilever timber.

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.
230 SURFACE WATER SUPPLY, 1912, PART VI.

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 flow. Affected by ice.

CHEYENNE RIVER BASIN. 

BELLE FOUECHE RIVEE NEAE BELLE FOUECHE, S. DAK.

Location. At the diversion dam of the Belle Fourche irrigation project, in sec. 2, 

T. 8 N., R. 2 E., li miles below Belle Fourche.

Records available. May 10, 1906, to November 30, 1906; January 1 to December 

31, 1912. Records of flow which did not account for certain diverted water which 

returned to the river below the station were maintained during 1910 and 1911, 

but have not been published.0 From May 26,1903, to June 23,1906, a station was 

maintained at the western edge of Belle Fourche. The records at the two points 

are not directly comparable, as Redwater River enters between and water is 

diverted from Belle Fourche River.

Drainage area. 4,270 square miles.

Gages. An inclined staff 300 feet below the diversion dam.

Cooperation. This station is maintained by the United States Reclamation Service, 

by whom the records are furnished.

o Records for 1912 show entire flow of river, total discharge being obtained from measurements of Inlet 

Canal, Belle Fourche River at diversion dam, and from records of stored water in Belle Fourche Reservoir.

SURFACE WATER SUPPLY, 1912, PART VI. 237

WHITE RIVER BASIN. 

WHITE RIVER NEAR INTERIOR, S. DAK.

Location. At the steel highway bridgenear 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, 1911, to December 31, 1912.

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.

Winter flow. Probably affected by ice.

Accuracy. Results fair after July 1.

WHITE RIVER BASIN. 239

WHITE RIVER AT WE STOVER, S. DAK.

Location. Until April 7, 1912, near the east side of sec. 32, T. 3 S., R. 29 E., 12 

miles south and slightly east from Murdo, S. Dak., a station on the Chicago, Milwaukee & St. Paul Railway; about 1 mile below entrance of Little White River; 

on and after April 8, at steel highway bridge about 40 rods above the old station.

Records available. August 25, 1911, to December 31, 1912.

Drainage area. Not measured.

Gage. Standard chain gage on steel highway bridge. Zero of gage is 2.0 feet higher 

than zero of original gage installed in 1911.

Channel. Composed of sand and silt; likely to scour and fill at flood stages.

Discharge measurements. Made from highway bridge.

Winter flow. Affected by ice.

Accuracy. Results poor owing to infrequency of gage heights and measurements 

and to the shifting character of channel.

NIOBRARA RIVER AT NIOBRARA, NEBR. '<

Location. At the Government highway bridge spanning the main channel inSE. -j

sec. 18, T. 32 N., R. 56 W., half a mile from the depot at Niobrara, 1J miles above

the mouth. No tributaries enter below. 

Records available. August 19, 1910, to December 23, 1912. From May 11, 1902,

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. Extremely shifting. Possibly within the influence of backwater from

Missouri River.

37228° WSP 326 14 16
242 SURFACE WATER SUPPLY, 1912, PAET VI.

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 are 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.

Location. At the Rock Island Railroad bridge at Luverne, Minn. Nearest tributary, Elk Creek, enters about 3 miles south of Luverne, Miun.

Records available. August 23, 1911, to December 31, 1912.

Gage. Vertical staff gage; datum unchanged.

Channel. Shifting at high stages; probably permanent at low stages.

Winter flow. Winter estimates 1911-12 have been based on observer's reports, 

climatologic data, and comparisons of flow of streams in drainage basins to the 

north and east.

Artificial control. No dams above the station used for power development.

Accuracy. Discharge curve is not well defined; records can not be considered 

better than fair.

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, 1909, to December

17, 1909; April 27, 1911, to October 31, 1912. 

Drainage area. 2,920 square miles (measured from Land Office map).
PLATTE RIVER BASIN. 245

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 the tie drives may cause backwater 

for a few days.

Discharge measurements. Made from bridge.

Winter flow. Ice causes backwater during the winter months and discharge measurements are made to determine the approximate flow.

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 basin there 

are adjudicated decrees for diversions of 3,060 second-feet from the headwaters 

of the North Platte, of which 121 second-feet are for diversion to Cocke la Pondre 

River.

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

reliable.

NORTH PLATTE RIVER AT PATHFINDER,, WYO.

Location. One-third mile south of Pathfinder and 800 feet below the mouth of the 

canyon, in sec. 24, T. 29 N., R. 84 W. The nearest tributary is Canyon Creek, 

which enters 2 miles above.

Records available. May 9, 1905, to December 31, 1912.

Drainage area. About 12,000 square miles. (Measured from Land Office map.)

Gage. Chain gage; datum unchanged.

Channel. Condition not known, as only final results are furnished.
PLATTE EIVEB BASIN. 247

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 diversions of 

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 and records furnished by United States Reclamation Service.

NOTE. The above records have been changed slightly from the records furnished by the United States 

Reclamation Service to conform with the computing rules of the United States Geological Survey.

NOKTH PLATTE KIVEK AT GUERNSEY, WYO.

Location. At the highway bridge, three-quarters of a mile west of Guernsey. The 

station is 6 miles above the Whalen diversion dam of the United States Reclamation Service. No important tributary between the two points.

Records available. June 14, 1900, to November 17, 1908; February 12 to October 

31, 1912.

Drainage area. 16,200 square miles.
250 SURFACE WATER SUPPLY, 1912, PART VI.

Gage. The gage was originally located at the highway bridge, but in 1902 it was 

moved to the railroad bridge 300 feet above. The datum of this gage was lowered 

10 feet June 13, 1908. When the station was reestablished in 1912 the gage was 

located at the highway bridge. The datum of the present gage is 0.24 foot lower 

than that of the original gage.

Channel. Shifting; frequent discharge measurements necessary.

Winter flow. Ice causes backwater during the winter months and discharge measurements are made to determine the approximate flow.

Controlled flow. The flow of North Platte River is controlled by the Pathfinder 

dam of the United States Reclamation Service. (See Pathfinder records.)

Diversions. Between this station and that at Whalen there are only a few minor diversions for irrigation, so the records at the two points are very nearly comparable.1

Accuracy. Although the channel is shifting, sufficient discharge measurements 

have been obtained to make the estimates of flow fairly reliable.

NORTH PLATTE 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. Nearest important tributary is Cottonwood Canyon Creek, an intermittent

stream which enters 1J miles below. 

Records available. May 1, 1909, to December 31, 1912. 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. 

Drainage area. Not measured.
252 SURFACE WATER SUPPLY, 1912, PART VI.

Gage. To determine the flow over the weir a vertical staff is used, with its zero 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 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 headgates, 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.

Controlled flow. 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 the Pathfinder reservoir and the WyomingNebraska line, exclusive of the diversion by the United States Reclamatipn 

Service. It is not known what percentage of these diversions is above the 

stations.

Cooperation. Station maintained and records furnished by the United States 

Reclamation Service.

Daily discharge, in second-feet, of North Platte River and Interstate canal at Whalen,

Wyo., for 1912.

254 SURFACE WATEB SUPPLY, 1912, PAET VI.

NORTH PLATTE RIVER AT HENRY, NEBR.

Location. At Henry post office, on the west line of sec. 3, T. 23 N., E. 58 W., within 

a half mile of the Nebraska-Wyoming line.

Records available. May 11 to September 17, 1912.

Drainage area. Not measured.

Gage. There are three separate channels and a vertical staff is placed in each. 

First two gages are set at the same datum; the gage in the third channel is set 1 

foot lower to avoid negative readings. The gage heights given are readings from 

the second channel gage.

Channel. Shifting; frequent measurements required.

Discharge measurements. Made from the bridge.

Winter flow. No data.

Diversions. Prior to September 1, 1912, there was an approved diversion of 220 

second-feet from the North Platte between the Wyoming-Nebraska State line and 

this station.

Accuracy. The estimates of daily discharge are based almost directly on the discharge measurements, which have been made at intervals of a few days.

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

the field data are furnished.

Discharge measurements of North Platte River at Henry, Nebr., in 1912.

NORTH PLATTE EIVEE NEAE MITCHELL, NEBE.

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.

Records available. June 3, 1901, to December 28, 1912. 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.
256 SURFACE WATER SUPPLY, 1912, PART VI.

Drainage area. 24,400 square miles.

Gage. Chain gage; datum lowered 1.00 foot on May 3, 1902, to avoid negative

readings.

Channel. shifting since 1911. 

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 1,968

second-feet from North Platte River between this station and Henry, and diversions of 75 second-feet from intervening tributaries. 

Accuracy. No discharge measurements were made during 1912, and the estimates

for that year are withheld until the rating is checked by further measurements. 

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

the field data are furnished.

Daily gage height, in feet, of North Platte River at Mitchell, Nebr.,for 1912.

PLATTE RIVER BASIN. 257

NORTH PLATTE RIVER AT SCOTTSBLUFF, NEBR.

Location. At the wagon bridge connecting Scottsbluff with Gehring, on the line 

between sees. 25 and 26, T. 22 N., R. 55 W. No important tributary within several 

miles.

Records available. June I to December 7, 1912.

Drainage area. Not measured.

Gage. Vertical staff.

Channel. Shifting; frequent measurements required.

Discharge measurements. Made from bridge.

Winter flow. No data.

Diversions. Prior to September 1, 1912, there were approved diversions of 171 

second-feet from the North Platte between this station and Mitchell and 4 secondfeet from intervening tributaries.

Accuracy. The estimates of discharge are based almost directly on the discharge 

measurements, which were made at intervals of a few days.

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

whom the field data are furnished.

NORTH PLATTE RIVER AT NORTH PLATTE, NEBR.

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 4£ miles above the junction 

with the South Platte.

Records available. February 25, 1895, to December 31, 1912.

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 3,455 

second-feet from the North Platte between this station and Scottsbluff and diversions of 923 second-feet from intervening tributaries.
PLATTE BJVER BASI3ST. 259

Accuracy. Owing to the very shifting channel the estimates have been obtained by 

the indirect method and can be considered only approximate.

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 20, 1912.

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.
PLATTE RIVER BASIN. 261

Channel. Extremely shifting; at this point the river flows in three channels known 

as the main, middle, and south channels. The gage is located in the main channel.

Discharge measurements. Made from bridge 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 aind Columbus. The large quantity of 

water diverted and the evaporation from the wide shallow channels frequently 

cause the flow to cease at this point during the late summer and fall.

Accuracy. Owing to the extremely 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, by whom 

the field data were furnished.

Discharge measurements of Platte River near Columbus, Nebr., in 1912.

PLATTE EIVER NEAR LESHARA, NEBR.

Location. At Mghway bridge, 2 miles southeast of Leshara, about sec. 34, T. 16 N., 

R. 9 E., 7 miles above the mouth of Otoe Creek.

Records available. May 19, 1911, to December 31, 1912.

Drainage area. Not measured.

Gage. Chain; datum unchanged.

Channel. Extremely shifting.

Discharge measurements. Made from the highway bridge. During 1912 discharge measurements were made from the railroad bridge near Valley.
PLATTE MV1B BASIN. 263

Winter flow. Data too meager to determine.

Diversions. Prior to September 1, 1912, there were approved diversions.of 2,500

second-feet for power and irrigation and 4,000 second-feet for power from Platte

River between the mouth of Loup River and this station. Below Leshara there

were approved diversions of 2,500 second-feet for power. 

Accuracy. Owing to the extremely shifting channel the estimates have been obtained

by the indirect method and can only be considered fair. 

Cooperation. Station maintained by the State engineer, by whom the field data

are furnished.

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, 1911, to October 31, 1912.

Drainage area. 235 square miles (measured from topographic sheets and King's 

Atlas).

Gage. Chain-gage type. June 6, 1912, the gage was moved 175 feet upstream. 

Although set to the original datum the present gage reads approximately 1 foot 

higher, due to the slope of the river.

Channel. A short distance below the original section is a low diversion dam which 

caused backwater whenever brush or drift collected on its crest. The present 

location is above the influence of the dam.

Discharge measurements. Made from car and cable.

Winter flow. Ice causes backwater during the winter months.

Diversions. Three large irrigation ditches divert water at a point 1 mile above the 

station. The smelter company has a pipe line which diverts water above the 

station, but as the tailrace of the power plant, which the pipe line supplies, is 

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 the station 31 second-feet.

Accuracy. The lodging of debris on the point of control makes the conditions at the 

original location somewhat uncertain, but at the present location conditions are 

favorable for accurate results.

COW CREEK NEAR SARATOGA, WYO.

Location. At highway bridge in sec. 36, T. 16 N., R. 84 W., 9 miles south of Saratoga.

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, 1912. 

Drainage area. Not measured. 

Gage. Vertical staff.

Channel. During 1912 there was no apparent shift in the channel. 

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

at ordinary stages. 

Winter flow. Ice causes backwater during the winter months and the observations

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. As there was no apparent shift in the channel during 1912 the estimates

are considered fairly reliable.

SPRING CREEK NEAR SARATOGA, WYO.

Location. At highway bridge about sec. 23, T. 17 N., R. 84 W. 5 and 2 miles southwest of Saratoga. No tributary between the station and the mouth, three-fourths 

of a mile below.

Records available. May 3, 1911, to October 31, 1912. ,
272 SURFACE WATER SUPPLY, 1912, PAET VI.

Drainage area. Not measured.

Gage. Vertical staff.

Channel. Somewhat shifting.

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

at ordinary stages.

Winter flow. Ice causes backwater during the winter months and discharge measurements are made to determine the approximate flow.

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.

Drainage area. Not measured.

Gage. Vertical staff.

Channel. Apparently permanent.

Discharge measurements. Made from private bridge.

Winter flow. Ice causes backwater during the winter months and discharge measurements are made to determine the approximate flow.

MEDICINE BOW RIVER NEAR MEDICINE BOW, WYO.

Location. At Johnson's ranch, in sec. 7, T. 20 N., B. 79 W., 14 miles southwest of 

Medicine Bow. The nearest tributary enters 3 miles below.

Records available. June 4, 1911, to November 30, 1912.

Drainage area. Not measured.

Gage. Vertical staff.

Channel. Shifting after high water.

Discharge measurements. Made from bridge and by wading.

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

discontinued.

Diversions. Prior to July 1, 1912, there were adjudicated diversions from Medicine 

Bow River of 230 second-feet, most of which are above the station.

Accuracy. Although there was a shift in the channel after the high water of 1912, 

sufficient discharge measurements have been made to make the estimates reliable, 

with the exception of the estimates from June 3 to July 14, during which dates 

the change occurred. These latter estimates may be 10 per cent or more in error.

Cooperation. Station maintained in cooperation with Johnson & Oownberg.

ROCK CREEK NEAR ROCK RIVER, WYO.

Location. At Phelan's ranch, in sec. 6, T. 20 N., R. 76 W., 1 mile southeast of Rock 

River. No important tributary between the station and the mouth, several 

miles below.

Records available. March 25, 1911, to November 17, 1912.

Drainage area. Not measured.

Gage. Vertical staff. In July, 1912, an automatic recording gage referred to the 

same datum was installed by the Rock Creek Conservation Co.

Channel. Shifting.

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

wading at ordinary stages.

Winter flow. Ice causes backwater during the winter months and discharge measurements are made to determine the approximate flow.

Diversions. Prior to July 1, 1912, there were adjudicated diversions from Rock 

Creek of 232 second-feet and from tributaries 73 second-feet, chiefly above the 

station.

Accuracy. As the channel shifts, the estimates have been obtained by the indirect 

method and can be considered only fair.

Cooperation. Station maintained in cooperation with the Rock Creek Conservation Co.

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, 1911, to November 30, 1912. From June 22, 1904, to 

October 31, 1905, a station was maintained at Decker's ranch, one-half 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 gage is referred to the same datum as the vertical staff used at 

first.

Channel. Practically permanent.

Discharge measurements. Made from bridge.

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 engineer of Colorado, 

by whom the data have been furnished as published.

NOTE. The above records have been changed slightly from the records of the State engineer to conform 

with the computing rules of the U.S. Geological Survey.

LARAMIE RIVER AND PIONEER CANAL NEAR WOODS, WYO.

Location. At the diversion dam for the Pioneer canal, in sec. 36, T. 14 N., R. 77 W.,

2 miles above Woods post office. The nearest important tributary is Fox Creek,

which enters 3 miles above. 

Records available. April 16 to December 31, 1912. From 1895 to 1900 and from

May 7 to November 11, 1911, a station was maintained at Woods Landing, in sec.

11, T. 13 N., R. 77 W. The records are not directly comparable, as Fox Creek

enters between and a few small ditches divert water. 

Drainage area. 438 square miles (measured from Hayden's Atlas). 

Gage. Vertical staff whose datum is the crest of the dam. This gage shows the water

passing over the dam. There is also a chain gage in the Pioneer ditch which

shows the water diverted. The sum of these two records is the total flow of

Laramie River above the Pioneer diversion. 

Channel. Practically permanent, as the concrete diversion dam is the contol.

Permanent in the canal. 

Discharge measurements. Made by wading during ordinary and low stages.

High- water measurements made at Woods Land, 5 miles above, and the intervening diversions measured. 

Winter flow. No data. 

Diversions. Prior to July 1, 1912, there were adjudicated diversions of 17 secondfeet, exclusive of the Pioneer canal, between this station and the one near Jelm,

which is almost on the Wyoming-Colorado line. 

Accuracy. Sufficient discharge measurements have been obtained to make the

estimates of flow reliable. 

Cooperation. This station is maintained in cooperation with the Laramie Water Co.,

by whom the greater portion of the field data are furnished . Check measurements

have been made by the United States Geological Survey.

LARAMIE RIVER AT TWO RIVERS, WYO.

Location. At highway bridge at Two Rivers post office, in sec. 5, T. 17 N., R. 74 W.

The nearest tributary is Little Laramie River, which enters one-fourth mile below

the station.

Records available. May 6, 1911, to October 31, 1912. 

Drainage area. 1,210 square miles (measured from King's Atlas). 

Gage. Vertical staff. 

Channel. Slightly shifting.

Discharge measurements. Made from the 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 from Laramie

River of approximately 350 seond-feet between this station and the one near

Woods. 

Accuracy. Although the channel is somewhat shifting, sufficient measurements

have been made to produce reliable results.

PLATTE RIVER BASIN. 291

LARAMIE RIVER NEAR WHEATLAND, WYO.

Location. At the Wheeler ranch, in sec. 35, T. 25 N., R. 69 W., 10 miles northwest 

of Wheatland. The nearest tributary is Sibylee Creek, which enters half a mile 

below.

Records available. April 13 to November 9, 1912.

Drainage area. Not measured.

Gage. Vertical staff.

Channel. Fairly permanent, as the control point is rapids a short distance below.

Discharge measurements. Made by wading, except during high water, when 

measurements are made from the bridge, 100 yards downstream.

Winter flow. Ice causes backwater during the winter months.

Diversions. The greater part of the flow of Laramie River is diverted above the 

station for irrigation. Prior to July 1, 1912, there were adjudicated diversions of 

1,273 second-feet from Laramie River, nearly all above the station.

Accuracy. Conditions are favorable for fairly accurate results and the estimates 

should be reliable, except that the discharge above 70 second-feet may be somewhat in error, owing to a lack of high-water measurements.

Cooperation. This station is maintained in cooperation with the Goldsborough Co.

LITTLE LARAMIE RIVER NEAR FILMORE, WYO.

Location. At May's ranch, in sec. 9, T. 15 N., E. 77 W., 1J miles south of Filmore 

post office, 4 miles below the junction of the North, Middle, and South forks, 8 

miles above the mouth of Mill Creek, the nearest tributary below.

Records available. May 14, 1911, to October 31, 1912.

Drainage area. Not measured.

Gage. Vertical staff.

Channel. Somewhat shifting.
PLATTE BIVEE BASIN. 293

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

at ordinary stages.

Winter flow. No data.

Diversions. Prior to July 1, 1912, there were adjudicated diversions of 450 secondfeet from the Little Laramie, both above and below the station.

Accuracy. Owing to the shifting character of the channelj the estimates of flow have 

been obtained by the indirect method and can be considered only fair.

Records available. May 1, 1911, to October 31,1912.

Drainage area. 421 square miles (measured from King's atlas).

Gage. Vertical staff.

Channel. Shifting during 1911 but apparently permanent during 1912.

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

at ordinary stages.

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

discontinued.

Diversions. Prior to July 1, 1912, there were adjudicated diversions from Little 

Laramie Eiver of 451 second-feet and from the tributaries 326 second-feet. 

These diversions are all above the station.

Accuracy. Conditions are favorable for accurate results and the estimates are considered reliable.

SIBYLEE CREEK NEAR WHEATLAND, WYO.

Location. In sec. 35, T. 25 N., E. 69 W., 10 miles west of Wheatland and half a mile 

above the mouth of the creek. No tributary within several miles.

Records available. May 23 to November 4, 1912.

Drainage area. Not measured.

Gage. Vertical staff 150 feet above the highway bridge.

Channel. Shifting. There is considerable fall between the station and the mouth, 

so there ia no backwater effect from Laramie Eiver.

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

at ordinary stages.

Winter flow. No data.

Diversions. Most of the water ia diverted above the station for irrigation. Prior to 

July 1, 1912, there were adjudicated diversions of 56 second-feet from Sibylee 

Creek and 62 from tributaries, all above the station. During the latter part of 

the irrigation season in 1912 the water was turned back into the river, as the 

ditches were out of repair.

Accuracy. Owing to the shifting channel no estimates of flow have been made.

Cooperation. Station maintained in cooperation with the Goldsborough Co.

NORTH LAEAMIE EIVEE NEAE WHEATLAND, WYO.

Location. At Wilson's ranch, in sec. 6, T. 25 N., R. 69 W., Sixth principal meridian, 

15 miles above the mouth and about 19 miles northwest of Wheatland. The 

station is 1 mile below the headgate of the North Laramie Land Co.'s ditch.

Records available. February 15 to December 31, 1912.

Drainage area. Not measured.

Gage. Vertical staff.

Channel. Apparently permanent.

Discharge measurements. Made by wading.

Winter flow. Ice causes backwater during the winter months and discharge measurements are made to determine the approximate flow.

Diversions. Water is diverted at a number of points above and below the station.

Accuracy. Owing to a lack of high-water measurements the estimates for discharge 

above 50 second-feet can only be considered fair; below that point they should 

be reliable.

Cooperation. Station maintained in cooperation with Mr. J. A. Whiting, of the 

North Laramie Land Co.

NORTH LARAMIE RIVER AT UVA, WYO.

Location. At highway bridge, in sec. 20, T. 25 N., R. 67 W., one-fourth mile west

of Uva, 800 feet above the mouth. 

Records available. May 21,1911, to October 31, 1912. 

Drainage area. Not measured. 

Gage. Vertical staff.
aoo SURFACE WATEE SUPPLY, 1912, PABT VI.

Channel. It is probable that the station is within the influence of backwater from 

Laramie River during high water. This is the only section on the lower river 

where an observer can be obtained.

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

at ordinary stages.

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

discontinued.

Diversions. Prior to July 1, 1912, there were adjudicated diversions from North 

Laramie of 59 second-feet and from the tributaries 70 second-feet. These diversions are all above the station.

Accuracy. The station has not been completely rated and no estimates of flow have 

been made.

PLATTE RIVEE BASIN. 301

CHUGWATEE CEEEK AT CHUGWATEB, WYO.

Location. At highway bridge in sec. 31, T. 21 N., R. 66 W., one-half mile from 

Chugwater. No important tributaries within several miles of the station.

Records available. May 22, 1911, to November 6, 1912.

Drainage area. Not measured.

Gage. Vertical staff, which was moved upstream February 6, 1912. All 1912 gage 

heights are referred to the present gage.

Channel. Reasonably permanent control for the original station was formed by a 

low diversion dam about 300 feet below the gage. February 6, 1912, the station 

was moved 300 feet upstream to be out of the influence of this dam.

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

at ordinary stages.

Winter flow. Ice causes backwater during the winter months and discharge measurements are made to determine the flow.

Diversions. Prior to July 1,1912, there were adjudicated diversions from Chugwater 

Creek of 178 second-feet and from the tributaries entering above the station 72 

seond-feet.

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

reliable.

Cooperation. Station maintained in cooperation with the Swan Land & Cattle Co./ 

which furnished many of the discharge measurements.

NOTE. Relation of gage height to discharge Jan. 1 to Mar. 23 affected by ice. 

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 September 30, 1912.

Drainage area. Not measured.

Gage. Automatic recording gage installed by State Engineer 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. There was no change during 1912.

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.
PLATTE BJVER BASIN. 307

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. It is also controlled by the antero reservoir located 45 miles 

upstream.

Diversions. There are court decrees for diversions of 1,076 second-feet from the 

South Fork above this station and the diversions of 1,926 second-feet from tributaries entering above.

Accuracy. Conditions are favorable for accurate results and the estimates are considered reliable.

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, and 600 feet above junction with the North Fork.

Records available. May 8, 1905, to December 1, 1912.

Drainage area. 2,160 square miles.

Gage. Inclined staff; datum unchanged.

Cnannel. Shifting, requiring frequent measurements.

Discharge measurements. Made from car and cable 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 flow is controlled to a certain extent by the Cheesman 

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 court 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 shifting, sufficient discharge measurements 

have been made to enable fair estimates of discharge to be made.

Cooperation. Station maintained in cooperation with the State engineer.

SOUTH PLATTE RIVER AT SOUTH PLATTE, COLO.

Location. In sec. 25, T. 7 S., R. 70 W., in the Pike National Forest, at 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 November 30, 1912. 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. (Measured from Hayden's Atlas.)

Gage. An automatic recording gage installed by the State engineer on 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.
312 SURFACE WATER SUPPLY, 1912, PART VI.

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. 

Diversions. No water is diverted between this station and that on the South Fork

at South Platte, there are court decrees for diversions of 20 second-feet from the

North Fork 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 reliable estimates of discharge to be made. 

Cooperation. Station maintained in cooperation with the State engineer.

314 SUEPACE WATER SUPPLY, 1912, PART VI.

SOUTH PLATTE 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 November 30, 1912.

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, an 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 

placed between the Fifteenth 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. The dam of the Farmers and Gardeners ditch, located below 

the station, was washed out July 18, 1912, which materially changed the channel.

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 diversions 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.

NOTE. The above records have been changed slightly from the records of the State engineer to conform 

with the computing rules of the United States Geological Survey.

SOUTH PLATTE EIVER NEAR KERSEY, COLO.

Location. At highway bridge in sec. 9, T. 5 N., R. 64 W., 1| miles north of Kereey, 

2 miles below the entrance of Lone Tree Creek, an intermittent stream, and 3 

miles below the mouth of Cache la Poudre River.

Records available. April 27,1901, to October 31,1903; March 1,1905, to December 

31, 1912.

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 floodwater 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.

NOTE. These estimates are the combined flow of the two channels.

SOUTH PLATTE RIVER AT JULESBURG, COLO.

Location. At highway bridge, about sec. 33, T. 12 N., R. 44 W., 1 mile south of 

Julesburg. No important tributaries between the station and the ColoradoNebraska 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 November 30, 1912.

Drainage area. 20,600 square miles.

Gage. When the station was reestablished in 1908 it was located at the new highway 

bridge, 2,000 feet upstream from the original station. The datum of the chain 

gage has remained unchanged since 1908.

Channel. Extremely shifting at times, requiring frequent measurements.

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 Nebraska and Wyoming 

and Crow Creek in Wyoming. There are also numerous floodwater decrees. 

Between the State line and the mouth, diversions of 206 second-feet from the 

South Platte have been granted in Nebraska.

Accuracy. Although the channel is shifting, sufficient measurements have been 

made to give fair discharge estimates prior to the high water in August, 1912. 

After that date the estimates are only approximate.

Cooperation. During 1912 this station was maintained in cooperation with the 

State engineer.

TARRYALL CREEK NEAR HAYMAN, COLO.

Location. At McLaughlin's ranch, in sec. 23, T. 11 S., R. 72 W., 6 miles northeast

of Hayman post office, in the Pike National Forest. Nearest tributary is a small

stream entering from the north just below. 

Records available. October 23, 1910, to June 30, 1912. 

Drainage area. Not measured. 

Gage. Vertical staff. 

Channel. Apparently permanent. 

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

wading at ordinary stages.

Winter flow. Ice causes backwater during the winter months. 

Diversions. There are court decrees for diversions of 205 second-feet from Tarryall

Creek between this station and the one near Jefferson. 

Accuracy. Owing to the meager gage heights daily discharge 'is only given for the

days when the gage was read. Results are considered fairly reliable. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

The following estimate of discharge was made by H. B. Waha: 

January 17, 1912: Estimate, 0.5 second-foot.

Daily gage height, in feet, and discharge, in second-feet, of Tarryall Creek near Hayman,

Records available. October 17, 1910, to July 11, 1912. 

Drainage area. Not measured. 

Gage. Vertical staff, which was lowered 0.66 foot. All readings have been referred

to the latter datum. 

Channel. Shifting. 

Discharge measurements. Made from the bridge at high water and by wading at

ordinary stages.

Winter flow. Ice causes backwater during the winter months. 

Diversions. There are court decrees for diversions from Jefferson Creek of 167

second-feet above the station and 21 second-feet below. There is a decree of 546

second-feet diversion from Jefferson Lake. 

Accuracy. Data insufficient for estimates of discharge. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

The following estimate of discharge was made by H. B. Waha: 

April 5, 1912: Estimate, 2 second-feet.

NORTH FORK OF SOUTH 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 6, 1912.

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 court decrees for diversions of 5.5 second-feet from the North 

Fork above the station, and a decree for diversions of 24 second-feet from tributaries above.

Accuracy. Owing to the high altitude of this station, alternate melting and freezing 

are likely to cause considerable diurnal fluctuations at certain seasons of the year, 

and the mean daily gage height based on one gage reading may be considerably 

in error. This, together with the scattering gage heights and shifting channel, 

makes the estimates at this station only fair.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

NORTH FORK OF SOUTH PLATTE RIVER AT CASSELLS, COLO.

Location. At Cassells, in sec. 11, T. 7 S., R. 74 W., in 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 3, 1912.

Drainage area. 128 square miles (measured from Forest Atlas).

Gage. Chain gage, which replaced a vertical staff reading to the same datum.

Channel. Somewhat 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 except for 2 second-feet from tributaries.

Accuracy. Owing to the high altitude of this station, alternate melting and freezing 

are likely to cause considerable diurnal fluctuations at certain seasons of the year, 

and the mean daily gage height based on night and morning readings may be 

somewhat in error. This, together with the somewhat shifting channel, makes 

the records only good.

Cooperation. Station maintained in cooperation with the State engineer.

GENEVA CREEK AT GRANT, COLO.

Location. In the Pike National Forest, at high way bridge in sec. 9, T. 7 S., R. 74 W., 

at Grant post office, 300 feet above the mouth of creek.

Records available. November 3, 1911, to December 6, 1912. From July 5, 1908, 

to November 3, 1911, a station was maintained at Sullivan's ranch, 3 miles above 

Grant. There are no tributaries between.

Drainage area. 74 square miles (measured from Fcrest atlas).

Gage. Vertical staff.

Channel. Somewhat shifting after high water.

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

at ordinary stages.

Winter flow. Ice causes backwater during the winter months, and discharge measurements are made to determine the approximate flow.

Diversions. There is a court decree for a diversion of 1 second-foot from Geneva 

Creek above the station, and a temporary reservoir decree for 1,480 acres from 

Geneva and Kerby creeks.

Accuracy. Owing to the high altitude of this station there are liable to be considerable diurnal fluctuations at certain seasons «of the year, due to alternate melting 

and freezing, and the mean daily gage height based on one gage reading may be 

considerably in error. This, together with the scattering gage heights, makes the 

estimates only fair.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

NOTE. Relation of gage height to discharge Jan. 1 to Mar. 11 and Nov. 24 to Dec. 6 affected by ice. 

Prior to high water in 1912 gage was attached to trees standing on the bank, but high water washed away 

bank leaving trees standing unsupported in stream. Gage heights, therefore, for period June to August 

are not published, being unreliable. On Sept. 12 a new vertical staff gage was securely braced to bank a 

few feet distant.

SCOTT GOMER CREEK * 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 3, 1912.

Drainage area. 21 square miles (measured from topographic sheet).

Gage. Vertical staff, moved to its present location, 2| miles below original site, 

September 4, 1909. Datum unchanged in new location, but has no determined 

relation to datum of original gage.

Channel. Shifting after high water.

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. Owing to the high altitude of this station there are liable to be considerable diurnal fluctuations at certain seasons of the year, due to alternate melting 

and freezing, and the mean daily gage height based on one gage height may be 

considerably in error. As there are so few gage heights, estimates have been 

made only for the days when the gage was read.

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., one-half mile below mouth 

of Chicago Creek, and one-fourth mile above entrance of Soda Creek and Virginia 

Canyon.

Records available. October 8, 1910, to September 27, 1912.

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 second-feet. 

During 1912 about 500 acre-feet were diverted.

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 lower 

_ water period.

Accuracy. Owing to the high altitude of this station, considerable diurnal fluctuations are likely to be caused at certain seasons of the year by the alternate melting 

and freezing, and the mean daily gage height based on one reading may be considerably in error. This, together with the shifting channel, makes the records 

only fair, or possibly good.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

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 November 4, 1912.

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, requiring frequent discharge measurements.

Discharge measurements. Made from footbridge and by wading. 

37228° WSP 326 14 22
338 SUBFACE WATER SUPPLY, 1912, PAET VI.

Winter flow. Ice causes backwater during the winter months and measurements

are made to determine the flow. 

Diversions. There are 110 court decrees for diversions between Idaho Springs and

Forkscreek. 

Artificial control. The natural flow is regulated to some extent by storage in various

ponds and reservoirs above. 

Accuracy. Owing to the very shifting channel the estimates have been obtained

by the indirect method and can only be considered approximate. The station

was discontinued, as the station near Golden gives much better results. 

Cooperation. Station maintained in cooperation with the State engineer.

NOTE. Discharge determined as follows: Mar. 25 to May 21, from a fairly well-defined curve; May 22 to 

June 18, by indirect method for shifting channels; June 19 to Oct. 31, from a poorly defined curve. Discharge interpolated for days on which gage was not read. Mean discharge January, February, and 

March estimated on basis of actual discharge measurements and open-water flow of latter part of March.

340 SURFACE WATER SUPPLY, 1912, PAET VI.

CLEAR CREEK NEAE GOLDEN, COLO.

Location. About 2 miles above Golden, in sec. 6, T. 4 S., R. 70 W., and a short 

distance below the headgate of the Golden ditch. The only tributary of importance between the station and the mouth is Ralston Creek, which enters about 12 

miles below.

Records available. December 4, 1908, to December 31,1909; June 8 to September 

24, 1911; January 1 to December 31, 1912.

Drainage area. Approximately 380 square miles.

Gage. Automatic recording gage, whose datum has remained unchanged.

Channel. Slightly shifting.

Discharge measurements. Made from car and cable located near the gage.

Winter flow. Ice causes backwater during the winter months, but discharge measurements are made to determine the approximate winter flow.

Diversions. Between Forkscreek and the station near Golden there is a court decree 

for a diversion of 26 second-feet by the Golden ditch. From March 5 to October 

22,1912, the ditch diverted water at an average rate of 18.3 second-feet, diverting 

a total amount of 4;I?0 second-feet. This does not represent the entire amount 

in the flume at the station as there is a waterway below Clear Creek station and 

above the measuring flume in the ditch. Below the Golden station there are 

decrees for diversions of 1,642 second-feet.

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

reliable.

Cooperation. Station maintained in cooperation with the Denver Reservoir Irrigation Co.

The following discharge measurements of the Golden ditch were made in the flume 

above the gaging station on Clear Creek, near Golden, Colo.:

NOTE. The above records have been changed slightly from the records of the State engineer to conform 

with the computing rules of the United States- Geological Survey.

BOULDER CREEK AT ORODELL, COLO.

Location. At Orodell station, in sec. 27, T. 1 N., R. 71 W., just below mouth of 

Fourmile Creek.

Becords available. March 18, 1907, to November 30, 1912. From May 14, 1895, 

to December, 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.
PLATTE RIVER BASIN. 345

Drainage area. 108 square miles. (From 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 whom the records are furnished.

Discharge measurements of Boulder Creek at Orodell, Colo., in 191%.

NOTE. The above records have been changed slightly from the records of the State engineer to conform 

with the computing rules of the United States Geological Survey.

SOUTH BOULDER CREEK NEAR EOLLINSVILLE, COLO.

Location. At highway bridge in sec. 35,-T. 1S., R. 73 W., 1 mile west of Rollinsville

in the Pike National Forest. The nearest important tributary, Jennie Creek,

enters 4 miles above.

Records available. September 10, 1910, to November 17, 1912. 

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 threfore

it is probable that the records represent the natural run-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.

SOUTH BOULDER CREEK AT ELDORADO SPRINGS, COLO. 1

Location. At the mouth of canyon at Eldorado Springs, in sec. 30, T. 1 S., R. 70 W., 

3 miles southwest of Marshall. No important tributaries within several miles.

Records available. May 15, 1895, to September 30, 1901; July 1, 1904, to November 30, 1912.

Drainage area. 125 square miles (measured from Eighteenth Annual Report, pt. 

4, and topographic sheets).

Gage. Vertical staff; datum unchanged.

Channel. Not'known, as only the computed estimates are received.

Discharge measurements. Made by wading.

Winter flow. Ice causes backwater during the winter months and measurements 

 are made to determine the flow.

Diversions. There are court decrees for diversions of 137 second-feet above the 

station and 1,658 second-feet below. There are also a number of flood-water 

decrees.

Cooperation. Since 1904 the station has been maintained by the State engineer, by 

whom the records are furnished. The records for 1904-1908 were published only 

in the reports of the State engineer.

NOTE. The above records have been changed slightly from the State engineer's records to conform with 

the computing rules of the U. S. Geological Survey. These estimates include the flow of Community 

canal.

CACHE LA POUDEE RIVER AT MOUTH OF CANYON, NEAR FORT COLLINS,

COLO.

Location. In sec. 15, T. 8 N., R. 70 W., 3 miles below the intake of the Fort Collins 

waterworks, and 12 miles above Fort Collins; one-half mile above the mouth of 

Lewstone Creek.

Records available. March 15, 1884, to October 15, 1901; February 3, 1910, to 

November 30, 1912.

Drainage area. 1,060 square miles.

Gage. An automatic recording gage installed November 30,1909; datum unchanged. 

No informationlivailable concerning the gage used from 1884 to 1901.

Channel. Practically permanent.

Discharge measurements. Made from car and cable.

Winter flow. Ice causes backwater during the winter months and measurements 

are made to determine the flow.

Diversions. There is a court decree for a diversion of 57 second-feet from Cache la 

Poudre River above the station and decrees for diversions of 526 second-feet from 

tributaries entering above, including Wyoming diversions. Below the station 

there are decrees for diversions of 3,105 second-feet from the,river. In addition 

there are a number of decrees for flood-water diversions. There are also decrees 

for diversions of 688 second-feet from Laramie River, 121 second-feet from the 

headwaters of North Platte River and 525 second-feet from the headwaters of 

North Fork of Grand River to the headwaters of the Cache la Poudre.

Cooperation. From 1884 to 1901 the records were maintained by Prof. L. G. Carpenter, of the Colorado State Agricultural College. Since 1910 the records have 

been furnished by the State engineer, by whom the station is maintained.

NOTE. The above records have been changed slightly "from the State engineer's records to conform 

with the computing rules of the United States Geological Survey.

LOUP RIVER AT COLUMBUS, NEBR.

Location. At highway bridge in eec. 25, T. 17 N., R. 1 W., at Columbus, No

tributaries between the station and the mouth of the river, 3 milea below.

Records available. October 13, 1894, to November 30, 1912.

Drainage area. 13,500 square milea.

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 ia 8.56 feet lower than that 

of the upper gage.

Channel. Extremely shifting.

Discharge measurements. Made from 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 are 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 the estimates of discharge only 

approximate.

Cooperation. During 1912 the station was maintained in cooperation with the State 

engineer, by whom the field data were furnished.

KANSAS RIVER BASIN. 

REPUBLICAN EIVEK 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., R. 8 W. Nearest tributary a small intermittent stream which enters a short distance below. 

Records available. June 6, 1904, to December 31, 1912. 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. 

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. Owing to the shifting channel the estimates can not be considered better

than fair or possibly good. 

Cooperation. During 1912 this station was maintained in cooperation with the State

engineer, by whom the field data were furnished.

BIG BLUE RIVER AT BEATRICE, NEBR.

Location. At Sixth Street bridge at Beatrice, Nebr. Nearest tributary a small

stream entering from the north a mile or more below. 

Records available. October 15, 1910, to December 31, 1912. Records of gage

heights have been kept by the United States Weather Bureau from January 1 to

July 31 of each year since June 1, 1905.

Drainage area. 3,363 square miles (United States Weather Bureau). 

Gage. Chain gage, which is owned by the United States Weather Bureau. 

Channel. Shifting.

Discharge measurements. Made from bridge.

Winter flow. Ice causes some backwater during a portion of the winter months. 

Flood discharge. The highest recorded stage was 25.6 feet above the present gage

datum and occurred May 29, 1903. 

Diversions. Prior to September 1, 1912, there were approved diversions of 841

second-feet for power from the Big Blue above Beatrice. Below the station the

approved diversions'amount to 500 second-feet for power. 

Accuracy. Owing to the 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 are furnished.

LITTLE BLUE RIVER NEAR FAIRBURY, NEBR.

Location. At highway bridge in sec. 26, T. 2 N., R. 2 E., 1J miles south of Fairbury.

Nearest tributary is a small stream entering half a mile above. 

Records available. May 23, 1908, to December 31, 1912. 

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 months. 

Artificial 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 no approved diversions from the

Little Blue between Blue Bluff and Fairbury nor from the intervening tributaries.

There was no diversion from Little Blue below Fairbury. 

Accuracy. Estimates have been made by indirect method for shifting channels and
