SURFACE WATER SUPPLY OF MISSOURI RIYER BASIN

1913.

AUTHORIZATION AND SCOPE OP WORK.

This volume is one of a series of twelve reports presenting results o 

measurements of flow made on streams in the United States during 

1913. Six of the reports for 1913 contain data for the year ending 

September 30 and the other six for the calendar year, as indicated ir. 

the table on page 8.

The data presented in these reports were collected by the Unitec 

States Geological Survey under authority implied in the organi 

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

Provided, That this officer [the Director] shall have the direction of the geologica 

survey and the classification of public lands and examination of the geological struc 

ture, mineral resources, and products of the national domain.

The work was begun in 1888 in connection with special studies o] 

water supply for irrigation. Since the fiscal year ending June 30 

1895, successive sundry civil bills passed by Congress have carriec: 

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 th< 

preparation of reports upon the best methods of utilizing the water resources.

Annual appropriations for the fiscal years ending June 30, 1895-1914-

In the execution of the work many private and State organizations 

have cooperated, either by furnishing data or by assisting in collecting 

data. Acknowledgments for cooperation of the first kind are made 

in connection with the description of each station affected, and o: 

the second kind on page 17.

8 SURFACE WATER SUPPLY, 1913, PART VI.

Measurements of stream flow have been made at about 3,000 points 

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

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

Islands. In July, 1913, about 13,880 gaging stations were being 

maintained by the Survey and the cooperating organizations in the 

United States. Many miscellaneous discharge measurements are 

made at other points. In connection with this work data were 

also collected in regard to precipitation, evaporation, storage reservoirs, river profiles, and water power in many sections of the country 

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

time to time.

PUBLICATIONS.

A report has been prepared for each year embodying the streamflow 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 the gaging stations maintained by the Survey to date, 

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

Prior to 1901 gage heights and discharge measurements were published in water-supply papers or bulletins and estimates of monthly 

discharge in annual reports; since 1901 both classes of data have been 

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

in twelve parts, as shown in the following table:

DEFINITION OF TERMS.

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

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

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

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

of water, as run-off in depth in inches, acre-feet, and millions of cubic 

feet. The units used in this series of reports are second-foot, secondfeet per square mile, run-off in inches, acre-foot, and millions of cubic 

feet. They may be defined as follows:

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

is a unit for the rate of discharge of water flowing in a stream. A 

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

rectangular cross-section 1 foot wide and 1 foot deep at an average
12 SURFACE WATER SUPPLY, 1913, PART VI.

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

unit from which others are computed by the use of the factors given 

in the tables of convenient equivalents (pp. 12-14).

"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-on3 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.

"Millions of cubic-feet" is a unit used to express quantities of 

water stored in reservoirs, and is most frequently used in studies of 

flood control.

The following terms used in these reports are not in common use:

"Discharge relation" is an abbreviation for the term "relation of 

gage height to discharge."

"Control," "controlling section," and "point of control," are terms 

used to designate the section or sections of the stream below the 

gage which determines the discharge relation at the gage. It should 

be noted that the control may not be the same section at all stages.

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

on the gage the gage height to which the surface of the river 

would fall if there were no flow.

CONVENIENT EQUIVALENTS.

computations:

EXPLANATION OF DATA.

For each regular current-meter gaging station the following data 

are given: Description of the station, list of discharge measurements, 

table of daily gage height, table of daily discharge, table of monthly 

and yearly discharge and run-off. For stations at weirs or dams the 

gage-height table is usually omitted.

In addition to statements regarding the location and installation 

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

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

gage .freight 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 of the data.

The table of daily gage height shows 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, though at many 

stations only one reading is made each day. At a comparatively few 

stations automatic gages are used, some of which give a continuous 

record of river stage in the form of a hydrograph and others a record 

printed at regular intervals, from which the mean daily gage height 

can be computed. 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
EXPLANATION OF DATA. 15

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.

In the tables of daily gage height the use of zeros in the hundredths 

place indicates the limits of accuracy to which the gage was read and 

to which the mean daily gage height was computed. If a gage is read 

to tenths or half-tenths once a day or to tenths twice a day, no zeros 

appear in the hundredths place for any stage. If the gage is read to 

half-tenths twice a day or to quarter-tenths or hundredths, regardless of the number of readings a day, the gage heights are published 

to hundredths, and zeros appear in the hundredths place, below a 

certain limiting stage. This limiting stage is so selected that the 

average error in the mean daily discharge, resulting from not using 

the mean daily gage height to hundredths above that stage, shall not 

be greater than 2 per cent. For automatic gages the allowable 

average error of the daily discharge has been taken as 1 per cent,. 

The selection of the percentage is arbitrary, but it should be noted 

that the maximum error will in all cases be twice the average error. 

In like manner half-tenths are used from the hundredths limit to 

another higher limit, above which only tenths are used. It is the 

aim to have the gage height observations at each gaging station recorded to the degree of refinement required by the above method of 

use, but in practice it is found necessary, in order to avoid confusion 

in the gage observer's record, to have the observations for all stages 

recorded to the degree of refinement required for low stages, which 

usually necessitates readings to hundredths of a foot.

The discharge measurements and gage heights are the base data 

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

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

recorded during the period for which it is applicable. It is not published in this report, but can be determined from the tables of daily 

gage heights and daily discharge by plotting gage heights in feet as 

ordinates and discharge in second-feet as abscissas.

The table of daily discharge determined from the rating table gives 

the discharge in second-feet corresponding to the mean of the gage 

readings observed each day.

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

gives the mean flow, as determined from the rating table, for the 

day when the mean gage height was highest. As the gage height is 

the mean for the day, it does not indicate correctly the stage when the 

water surface was at crest height, and the corresponding discharge
16 SURFACE WATER SUPPLY, 1913, PART VI.

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 pages 11-12, are based.

The base data presented in this report, unless otherwise stated in 

description of station, have been collected by the methods commonly 

used at current-meter gaging stations and described in standard textbooks. (See Pis. I and II.)

ACCURACY OF FIELD DATA AND COMPUTED RESULTS.

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

of channel and of the relation between discharge and stage, and (2) 

on the accuracy of observation of stage, measurement of discharge 

and interpretation of data.

In order to give engineers and others information regarding the 

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

daily discharge tables, stating the probable accuracy of the rating, 

curves used, and an accuracy column is inserted in the monthly discharge table. For the rating curves "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, the number of gage readings per day, the range of the 

fluctuation in stage, 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. On 

this account the computations of "second-feet per square mile" and 

"run-off (depth in inches)" have not been made for stations draining 

areas having an annual rainfall of less than 20 inches, nor for those 

stations draining areas of over 20 inches of rainfall for which it is

believed that the computations would be uncertain and misleading 

because, of the presence of large noncontributing districts in the measured drainage area, of omitting estimates of water diverted for irrigation or other use, or of artificial control or unusual natural control 

of the flow of the river above the gaging station. All values of 

"second-feet per square mile" and "run-off (depth in inches)" previously published by the Survey should be used with extreme caution, and such values in this report should be used with care because 

of possible inherent sources of error not known to the Survey.

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

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

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

the Reclamation Service. The Legislature of the State of Montana 

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

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

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

of Montana, which reads as follows:

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

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

this work as much as possible with the United States Geological Survey and the Montana 

' Experiment Station; such measurements to be made on streams in order of their importance, provided that measurements already made, if deemed reliable, maybe adopted.

This fund was expended largely on work in connection with the 

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

who worked directly with the Geological Survey.

The expense of work on the Crow Reservation in Montana, the 

Standing Rock Reservation in North and South Dakota, and the

Pine Ridge and Rosebud reservations in South Dakota was borne 

by the Office of Indian Affairs.

The work in Nebraska was carried on by the State engineer, Mr. D. 

D. Price, who paid all field expenses.

Other assistance in collecting records in the Missouri River basin is 

acknowledged in connection with the descriptions of the stations.'

DIVISION OF WOKK.

BEAVERHEAD RIVER AT BARRATTS, MONT.

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

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

Records available. August 12, 1907, to December 31, 1913. 

Drainage area. Not measured. 

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

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

chain gage the same as that of the staff gage.
MISSOURI RIVER PROPER.

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

Discharge measurements. Made from downstream side of the bridge.

Winter flow. Stream remains open during the winter months.

Diversions. Numerous diversions are made above -the station. Decreed water 

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

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

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

canal, appropriating 4,000 inches; and Beaverhead canal, diverted just north of 

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

canal with a carrying capacity of 6,000 inches.

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

the post office of Red Rock, below which it is called the Beaverhead. The principal 

tributaries to the Beaverhead above the station are Grasshopper Creek, 12 miles south 

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

NOTE. Discharge determined from a rating curve fairly well defined between 1,560 and 28,000 secondfeet. Discharges for the period Jan. 1 to Mar. 19 represent flow at Canyon Ferry, about 40 miles below 

Toston, and were furnished by Montana Power Co. No large tributaries enter between the two stations, and the flow at Canyon Ferry during this period ought not to exceed that at Toston by more than 

5 per cent.

NOTE. Estimates for the period Jan. 1 to Mar. 19 represent flow at Canyon Ferry, about 40 miles below 

Toston.

MISSOURI 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, 1913. 

Drainage area. 18,300 square miles. 

Gage. Standard chain gage attached to bridge. 

Control. Probably permanent except at extreme flood stages. 

Discharge measurements. Made from lower side of bridge. 

Winter flow. Affected by ice.

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

stations at Toston and Cascade.

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 being little used because of its high 

banks and great variation in flow and the difficulty of diversion.

NOTE. Bridge and gage destroyed by high water Apr.16,1913. On May 2, when the station was visited, 

it was found that the bench marks had been destroyed by a construction crew. A temporary staff gage 

was installed on the left abutment of the old bridge. The discharge measurement referred to this gage 

plotted 3.25 feet too low on the station gage height scale. The channel at this station being permanent, 

it was assumed that the temporary gage read 3.25 feet too low, and all readings made on this gage have 

been increased by that amount. The temporary gage was read May 2 to July 31, when the station was 

discontinued. Daily discharge was determined from the rating curve for 1910 to 1912 which was well defined for those years and for 1913 to April 15 and fairly well defined after April 15, on account of the method 

of correcting gage heights.

Boulder, Mont.

Records available. April 27 to December 31, 1913. 

Drainage area. Not measured. 

Gage. Staff gage fastened to a flume 2.5 feet upstream from crest of weir. Gage

heights give the head on the weir. 

Control. Flume. 

Discharge measurements. Flow measured by a sharp-crested weir 4.85 feet long

with end contractions. Discharge computed by Francis formula, correcting for

end contractions and velocity of approach. 

Winter flow. Affected by ice.

Regulation. No regulation or diversion above the station. 

Accuracy. Results should be good.

PRICKLY PEAR CREEK AT EAST HELENA, MONT.

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

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

tributaries entering Prickly Pear Creek above the station are McClellan and 

Lump Gulch creeks; Tenmile and Silver creeks come in below.

Records available. July 18, 1908, to July 31, 1913, when station was discontinued.

Drainage area. Not measured.
44 WATER STJPPLY, 1913, PABT vi.

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

unchanged.

Control. Rocky, clean, and nonshifting. 

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

or by wading just below the gage. 

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

greater part of the water being diverted below the station. 

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

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

LUMP GULCH CREEK NEAR CLANCY, MONT.

Location. In sec. 4, T. 8 N., R. 3 W., at the ranch of Charles 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 July 31,1913, when station was discontinued.

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 foot lower than that previously used. All gage heights for 1910 were reduced to new datum.

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

Discharge measurements. Made by wading.

Winter flow. Affected by ice.

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

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

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

appropriated.

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

NOTE. Accuracy for January, February, and March reduced because of possible effect of ice; accuracy 

for April, May, and June reduced on account of there being but one reading per day. When the snow is 

going off in the mountains this does not represent the mean flow: The results are probably low.

SUN RIVER AT FORT SHAW, MONT.

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

Records available. May 16, 1912, to December 31, 1913. A station on Sun River.

at Sun River, maintained previous to 1912, gave practically the same data. 

Drainage area. Not measured. 

Gage. Staff gage put in September 1,1913, on the right bank about 1,000 feet above

footbridge; gage heights beginning September 1, 1913, referred to that gage.

Previous to that date a standard chain gage fastened to the footbridge near the

right bank was used. 

Control. Probably permanent. 

Discharge measurements. At high and medium stages made from footbridge

below gage; at low stages made by wading. 

Winter flow. Affected by ice. 

Diversions. 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

Fort Shaw canal of the United States Reclamation Service takes out about 200

second-feet during the irrigation season.

Storage. Willow Creek reservoir has a capacity of 84,320 acre-feet. 

Accuracy. Conditions for obtaining accurate discharge data good; results for 1912

and 1913 only fair, owing to errors in the gage.

SUN BIVEB BASIN. 59

Drainage area. Not measured.

Gage. Standard chain on right bank near observer's house.

Control. Permanent.

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

above the gage.

Diversions. Adjudicated water rights above station amount to 36.2 second-feet 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 has also 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 RecLimation Service being diverted from Sun River below the 

mouth of Willow Greek.

Storage. Willow Creek dam, 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 the Sun River 

project.

Accuracy. Conditions for obtaining accurate discharge data are excellent.

MAEIAS BTVEB BASIN. 65

TWO MEDICINE RIVER AT FAMILY, MONT.

Location. In the NE. i 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, 1913.

Drainage area. 368 square miles.

Gage. Overhanging chain gage installed September 18, 1913, on left bank of stream 

directly back of the mission buildings. The datum of original gage, which was 

at same site as present gage, was lowered 0.95 foot July 21, 1908. The original 

chain gage and bench marks were destroyed by flood of June 2,1913, and on June 

10 a staff gage was installed at a different datum on the left bank about 125 feet 

above site of chain gage. On July 23 this staff gage was removed to location of 

the chain gage and was set to read 1.85 feet higher than staff gage installed June 

10. The present chain gage, installed September 18, was set to read 1.00 foot 

higher than the staff gage installed July 23 at same site.

Control. Gravel.

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

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

about 3 miles above the mission.

Winter flow. Affected by ice.

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

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

the Holy Family Mission. The United States Reclamation Service has under 

construction a project which will use about 200 second-feet of water for irrigating 

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

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

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

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

Accuracy. Results good except for winter months.

BADGER CREEK NEAR FAMILY, MONT.

Location. In the NE. J 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, 1913. 

Drainage area. 224 square miles.
68 SURFACE WATER SUPPLY, 1913, PART VI.

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.

Control. 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 good.

NOTE. Gage heights June 5 to July 16 read on upper gage, about one-fourth mile above regular g 

This upper gage was established June 5, because of the unsatisfactory overflow conditions at the res 

gage; but at low water the upper-gage section is very poor because it is wide and irregular, so the read 

could not be taken there except at medium and high stages.

and the other for the remainder of the year. The use of two curves is due to the fact that two gages are 

read and not to a change In channel. (See footnote to daily gage heights.) Discharge interpolated June 4.

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, 1913.

Drainage area. 186 square miles. (Revised from 155 square miles.)
74 SURFACE WATER SUPPLY, 1913, PART VI.

Gage. Chain gage and a Bristol automatic. 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 Bistol automatic gage was installed April 1, 1911, but 

the chain gage is still read daily.

Control. Shifts at high stages.

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

the gage; low-stage measurements 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,

NOTE. Discharge determined as follows: Apr. 7 to May 19 and June 26 to Nov. 27, from a rating curve 

well denned between 3 and 310 second-feet and fairly well defined at other stages; May 20 to June 18, from 

a fairly well denned rating curve; June 19-25, by indirect method for shifting channels; Apr. 1-6 and Nov. 

28-30, estimated. Discharge interpolated May 24-26. Discharge Aug. 11-15 estimated at 5.0 second-feet; 

Aug. 25-31 at zero flow; Sept. 1-30, at 0.2 second-foot; Oct. 1-4, at zero flow.

84 SURFACE WATER SUPPLY, 1913, PART VI.

TETON RIVER AT STRABANE, 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, 

post office.

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

to December 31, 1913.

Drainage area. 140 square miles.

Gage. Standard chain gage fastened to upstream side of bridge near" the center of 

the river, installed March 23, 1911; previous to that date several different gages 

and datums were used.

Control. Shifts at high stages; current swift. 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 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 of Teton River in the reservoir about 5 miles north of the gaging station. 

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

acre-feet by raising the top of the dam 20 feet. The reservoir will serve 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 difficult because 

of shifting channel.

Control. 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 waters 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 very good.

MUSSELSHELL BIVER BASIN. 101

MUSSELSHELL RIVER AT HARLOWTON, MONT.

Location. In sec. 26, T. 8 N., B. 15 E., at the highwaybridge 1 mile south of Harlowton. 

Records available. July 11,1907, to December 31,1913. A station was maintained

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

Drainage area. Not measured. 

Gages. Standard chain gage on the upstream side of the public highway bridge

installed May 24, 1909, at a datum 0.52 foot higher than that previously used.

All gage heights for 1909 were corrected to the new datum.

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

Discharge measurements. Made from bridge or by wading. 

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

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

A minimum discharge of 2 second-feet has been recorded during the Irrigation

season at this station.

MUSSELSHELL EIVEE BASIN". 107

AMERICAN FORK NEAR HARLOWTON, MONT.

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

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

Becords available. July 28, 1907, to December 31, 1911, and May 19, 1913, to 

December 31, 1913.

Gage. Chain fastened to upper rail of small wagon bridge.

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

Discharge measurements. Made from the bridge or by wading.

Winter flow. Affected by ice.

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

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

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

Accuracy. Open-season records good.

MILK RIVER BASIN. 117

MILK RIVER AT HAVRE, MONT.

Location. In the SE. £ SE. £ 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, 1913.

Drainage area. Not accurately determined.

Gage. Chain fastened to bridge rail on the downstream side.

Control. 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 section 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 partly 

constructed but no water has been diverted. There are no other important 

irrigation rights above Havre, but farther downstream are five large canal systems 

supplied directly from Milk River and irrigating about 22,000 acres. Preliminary 

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

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

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

to 125 second-feet, the priority of the other rights not being touched upon. 

Although no provision for storage has been made by the above claimants, the 

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

Reclamation Service in connection with its Milk River irrigation project now 

under construction.

Accuracy. Frequent discharge measurements are necessary to properly define the 

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

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

for several months.

MILK RIVER AT MALTA, MONT.

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

Malta, Mont.

Records available. July 31,1902, to December 31,1913. 

Drainage area. Not accurately determined. 

Gage. Chain fastened to handrail on downstream side of bridge. 

Control. Sandy; shifts during floods.
120 SUEFACE WATEE SUPPLY, 1913, PAET VI.

Discharge measurements. Made from bridge or by wading.

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

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

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

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

States Reclamation Service has 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 second-feet.

126 SURFACE WATER SUPPLY, 1913, PART VI.

BATTLE CREEK 1 NEAR CHINOOK, MONT.

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

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

Records available. April 22, 1905, to December 31, 1913.

Drainage area. Not measured.

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

Control. 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 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 Battle Creek. The aggregate appropriation for these canals is 78 second-feet. A number of diversions are made 

from this stream in Canada.,

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.

ROCK CREEK NEAR HINSDALE, MONT.

Location. In sec. 10, T. 31 N., R. 36 E., at Ottenstror's ranch, about 2 miles below 

the headgates of Rock Creek canal and 6 miles northeast of Hinsdale.

Records available. April 19, 1912, to December 31, 1913. 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.
MILK KIVEE BASIN. 129

Control! 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 good.

MILK EIVEE BASIN. 133

PEIVATE CANALS IN MILK RIVER VALLEY. 

GENERAL FEATURES.

Since 1905 a number of stations have been maintained on private 

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

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

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

Hill and Blame counties and are used to irrigate lands in the vivinity 

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 

backwater effects for long distances above. They are put up under 

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

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

establish the correct relation between gage height and discharge it 

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

Frequent discharge measurements are necessary to obtain reliable 

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

are made by wading.

PARADISE VALLEY CANAL NEAR CHINOOK, MONT.

Location. Near the headgate at Rudolph Friede's ranch; reached by driving along,

the south river road from Chinook.

NOTE. Discharge determined as follows: Previous to June 28, by indirect method for shifting channels; 

June 28 to July 28, from a rating curve fairly well defined between 4 and 12 second-feet, and poorly defined 

at other stages; after July 28 by indirect method for shifting channels. From Apr. 6 to May 15 the headgates 

were closed, but a small quantity of water was leaking through the headgates; this was estimated for the 

period Apr. 6-20 at 0.1 second-foot. From May 16-31, the flow came from waste water from the Cook canal 

for the periods May 16-18 and May 22-31 this was estimated at 0.1 seeond-foot. The canal headgates were 

opened May 31, at 1 p. m., and were closed Aug. 25. A very little water leaked through the headgates 

after this date.

NOTE. Discharge determined as follows: July 1-31, from a fairly well-defined rating curve; May and 

June, estimated from discharge measurements. Canal dry July 12-24. Head-gates opened May 27 and 

closed for the season July 28. Checks were put in the canal just below the gage and removed at frequent 

intervals during the irrigating season, causing sudden changes in the relation of gage height to discharge.

.miles west of Chinook.

Records available. June 21, 1903, to December 31, 1913. 

Gages. The high water 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

NOTE. Station was visted Apr. 14, and it was found that the staff gage had been washed out. A temporary staff gage was put in at a section about 200 feet above the old gage, and this was replaced by a chain 

gage May 9. The datum is the same as that of the gage used during 1912, but the control and conditions of 

channel are different. On Oct. 5 the gage was moved to a new United States Reclamation Service camp 

several miles below the former site, the old camp being abandoned. Gage heights after Oct. 4 read at the 

new site.

150 SURFACE WATER SUPPLY, 1913, PART VI.

Gage. Vertical staff on left bank. 

Control. Rock. One channel at all stages.

Discharge measurements. Can be made by wading at certain stages. When too 

deep to be waded, can be made by measuring flow at Fishing bridge and adding 

the inflow.

Winter flow. Ice forms in the winter, but the falls remain open. 

Accuracy. Data insufficient for estimates of discharge. 

Cooperation. Gage heights and transportation are furnished by the Yellowstone

National Park.

Estimates withheld for additional measurements. 

The following discharge measurement was made by R. C. Pierce: 

September 12. Gage height, 2.31 feet; discharge, 2,160 second-feet.

Daily gage height, in feet, of Yellowstone River near Canyon station, Yellowstone National

Park, for 1913.

YELLOWSTONE RIVER AT HUNTLEY,. MONT.

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

below Huntley, Mont., 1 mile below Pryor Creek. Station replaces that formerly 

maintained at Junction.

Records available. October 1, 1907, to December 31, 1913. A station was maintained May 10, 1906, to December 31, 1907, at Junction, Mont., where the flow 

is practically the same as at Huntley.

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 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 EIVER AT INTAKE, MONT.

Location. At the Lower Yellowstone diversion dam at Intake in NW. J sec. 36, T. 

18 N., R. 56 E., 18 miles below Glendive, Mont.

Records available. January 1,1911, to December 31,1913. Records were obtained 

at Glendive, 18 miles above by the War Department and Department of Argiculture from 1893 to 1903, and by the Geological Survey from August 1, 1903, to 

December 31, 1910.

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.

NOTE. Discharge determined from a rating curve which is believed to be fairly well defined and which 

was obtained by a curve of gage height relation from the rating curve for the old station at Glendive. Mean 

discharge estimated as follows: Feb. 16 to 28 at 4,000 second-feet; Mar. 1 to 15 at 6,000 second-feet; Mar. 23 

to 31 at 15,000 second-feet; Apr. 1 to 10 at 25,000 second-feet.

Attention is called to the probability that the daily discharges published in Water-Supply Paper 326 for 

October to December, 1912, may be considerably in error because of the gage error found on Apr. 21,1914. 

Hydrograph comparisons indicate that this error probably existed after Oct. 18,1912. «

SWEETGRASS CREEK BELOW MELVILLE, MONT.

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

Lindsay Land Co.

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

April 1, 1909, to December 31, 1913.

Drainage area. 137 square miles (measured on topographic sheets).

Gage. Staff on left bank near observer's house.

Control. Bed composed of clean gravel; shifting.

Discharge measurements. Made by wading.

Winter flow. Affected by ice.

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

YELLOWSTONE BIVEE BASIN. 177

BIGHORN RIVER NEAR HARDEST, MONT.

Location. On the Grow Indian Reservation, in the SW. J sec. 13, T. 1 S., R. 33 E., 

at the bridge of the Chicago, Burlington & Quincy Railroad about half a mile 

above junction of Bighorn and Little Bighorn rivers, 2 miles from Hardin, Moat.

Records available. June 16,1904, to December 31,1913.

Drainage area. 20,700 square miles.

Gage. A chain attached to west span of railroad bridge was read up to October 11, 

1913. After that date a temporary staff gage, set to the datum of the chain gage but 

located 20 feet farther downstream, was read. The staff gage reads 0.07 lower 

than the chain, owing to its different location. Gage heights after October 1] 

have been corrected to chain-gage datum.

Control. Composed of gravel; free from vegetation.

Discharge measurements. Made from railroad bridge.

Winter flow. Affected by ice.

Diversions. Water is diverted a few miles above the station by a private irrigation 

company to irrigate land on west side of the river.

YELLOWSTONE RIVER BASIF. 179

SHOSHONE RIVER AT CORBETT DAM, WYO.

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

miles below Cody, Wyo.

Records available. April 20, 1908, to December 31, 1913.

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

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

this station and Cody, drains only about 25 square miles.

Gage. Forty feet upstream from 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 discharge over the crest was developed by W. A. Lamb from measurements at 

Cody, Wyo.: Q=3.50 BH1 -68 . The dam is of reinforced concrete, of the buttressed type, having on the upstream side a deck 2$ feet thick, sloping 1 to 1, and 

supported by buttresses 2 feet thick spaced 14 feet on centers; it raises the lowwater 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, regulates the flow.

Cooperation. Gage heights and discharge into Corbett tunnel furnished by United 

States Reclamation Service.

NOTE. Discharge determined by adding the flow through the tunnel to the flow over the crest of the dam. 

Record of daily discharge through the tunnels was furnished by the United States Reclamation Servtoe. 

The flow over the dam was obtained from a rating table computed by the formula S.SOBH1 .88 (see station 

description). Discharge Feb. 4-5 interpolated. Water was shut off at the Shoshone dam from 5.30 p. m. 

Feb. 15 to 2 a. m. Feb. 16, but the gage was read at such times so that this fact does not appear; proper 

allowance made in determining discharge Feb. 15 and 16. Discharge interpolated Nov. 5-9 and Dec. 2-18, 

as total flow was going through the sluice gates. These are the only periods during which the sluice gates 

were open.

LITTLE BIGHOEN EIVEE NEAR CROW AGENCY, MONT.

Location. On the Crow Indian Reservation at the Chicago, Burlington & Quincy 

Railroad bridge, 2 miles south of Crow Agency, Mont., in the W. J sec. 18, T. 2 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, 1913.
YELLOWSTONE EIVEE BASIN. 187

Drainage area. 1,190 square miles.

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 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.

Control. Permanent. Bed of the stream is coarse gravel and cobblestones. Current 

is broken by the piers of the bridge and 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. Crow Agency ditch diverts water between the station and the old 

station at Crow agency.

150 feet farther downstream on the left bank,"was used. Datum of chain gage is 

0.08 foot lower than tha't of staff gage. Control points also different.

Control. 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 flow. Affected by ice.

Accuracy. High-water measurements sufficient to define a rating curve for use in 

making estimates of daily discharge for 1912 and 1913 were obtained during 1914.

CANNONBALL RIVER BASIN. 

CANNONBALL RIVER NEAR STEVENSON, N. DAK.

Location. On the Standing Rock Indian Reservation, near 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 31,1913.
CANNONBALL RIVER BASIN. 197

Drainage area. 3,670 square miles.

Gages. Chain on projecting cantilever timber, on west side of river.

Control. At the rapids 600 feet below the gage the bed is of clean gravel and stones. 

Bed of stream composed of gravel and stones, in places covered with silt to the 

depth of 1 foot. During floods the silt may be washed away and later redeposited 

at some points.

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

GRAND RIVER BASIN. 201

GRAND RIVER NEAR WAKPALA, S. DAK.

Location. On the Standing Rock Indian Reservation, a new steel highway bridge, 

4 miles south of Wakpala, S. Dak., a station on Chicago, Milwaukee & St. Paul 

Railway, in or near sec. 8, T. 19 N., R. 29 E.

Records available. September 9,1911, to December 31, 1913.

Drainage area. 5,300 square miles.

Gage. Standard chain gage on foot guardrail at downstream side of highway bridge.

Control. Shifting; bed composed of soft silt or quicksand.

Discharge measurements. Made from highway bridge; at very low stages measurements may be made by wading at the ford 40 rods below the bridge.

Accuracy. Results poor, owing to infrequency of gage readings and measurementa 

and shifting character of the stream.

CHEYENNE RIVER BASIN. 

BELLE FOURCHE EIVER NEAR BELLEFOURCHE, S. DAK.

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

T. 8 N., R. 2 E., 1£ miles below Bellefourche.

Records available. May 10 to November 30, 1906; January 1, 1912, to December 

31, 1913. From May 26, 1903, to June 23, 1906, a station was maintained at the 

western edge of Bellefourche. 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.

Gage. An inclined staff situated 300 feet below the diversion dam shows the flow 

passing the diversion dam.

Cooperation. Station maintained and records furnished by United States Reclamation Service.

Daily discharge, in second-feet, of Belle Fourche River near Bellefourche, 8. Dak., for 1913.

WHITE BIVEB BASIN.

WHITE RIVER NEAR INTERIOR, S. DAK.

Location. On the Pine Ridge Indian Reservation, at steel highway bridge near 

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 Chicago, Milwaukee & St. Paul Railway.

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

R. 18 E.; August 24, 1911, to December 31, 1913.

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

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

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

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

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

of the river near southwest corner of NW. \ sec. 17.

Control. 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 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 highway bridge.

Winter flow. Relation of gage height to discharge probably affected by ice during 

January, February, March, and December.

Accuracy. Results fair.

WHITE RIVER NEAR WESTOVER, S. DAK.

Location. In sec. 32, T. 3 S., R. 29 E., on the Rosebud Indian Reservation at 

steel highway bridge near Westover about 12 miles south and slightly east from 

Murdo, S. Dak., a station on Chicago, Milwaukee & St. Paul Railway, and about 

1 mile below entrance of Little White River; about 40 rods above location of 

original station, established in 1911.

Records available. August 25, 1911, to December 31, 1913,

Drainage area. 7,850 square miles.

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

than zero of original gage installed in 1911. August 18,1913, a staff gage reading 

same as chain gage was fastened to downstream face of left abutment. This gage 

was installed in order to obtain more frequent and accurate readings.

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

Discharge measurements. Made from highway bridge.

Winter flow. Affected by ice.

LITTLE WHITE RIVER NEAR WESTOVER, S. DAK.

Location. At C. H. Kendall's ranch, on the Rosebud Indian Reservation, about 4 

miles south of Westover and about 2 miles above mouth of the stream.

Records available. June 26, 1912, to December 31, 1913.

Drainage area. 1,590 square miles.

Gage. Standard projecting timber chain gage installed September 18, 1913, about 

5 or 6 rods below the cable and on right bank. A staff gage about 10 rods below 

cable was used during 1913 prior to September 18. A staff gage about 30 rods 

below the cable was used during 1912. All gages have been referred to the same 

datum.

Control. Sandy and shifting.

Discharge measurements. Made from the cable or by wading.

Winter flow. Affected by ice.

Accuracy. Gage heights for 1913 considered more accurate than those for 1912, 

owing to better position of gages. As sufficient measurements were obtained to 

define a curve, results should be fair.

Discharge measurements of Little White River near Westover, S. Dak., in 1913.

NIOBRARA RIVER AT NIOBRARA, NEBR.

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

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

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

Records available. August 19,1910, to July 26,1913, when station was discontinued 

in favor of station near Lynch, Nebr. 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.

Control. Extremely shifting. Station is possibly within the influence of backwater 

from Missouri River.

Discharge measurements. Made from bridge.

Winter flow. 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 the fact that no discharge measurements 

were made during 1913, no estimates of discharge have been made,

Cooperation. Field data furnished by State engineer.

BIG SIOUX BIVEB BASIN. 

ROCK RIVER AT LTTVERNE, MINN.

Location. At Chicago, Rock Island & Pacific Railway bridge at Luverne, 3^ mile

above mouth of Elk Creek.

Becords available. August 23, 1911, to December 31, 1913. 

Drainage area. 440 square miles. 

Gage. Vertical staff gage.

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

Winter flow. Affected by ice; observations discontinued. 

Begulation. Low rock dam above gage does not regulate the flow, but raises water

level about 2 feet; discharge relation not affected thereby. 

Accuracy. Owing to the liability to shift, the records can not be considered better

than fair.

PLATTE BIVER BASIN.

NORTH PLATTE EIVER ABOVE PATHFINDER RESERVOIR, WYO.

Location. About 25 miles above Pathfinder dam, in sec. 27, T. 26 N., R. 84 W., 

three-fourths mile below mouth of Black Canyon, and 900 feet below mouth of 

Lost Creek, the nearest tributary. Backwater from Pathfinder reservoir reaches 

within 2J miles of station.

Records available. October 7 to December 4, 1913.

Drainage area. Approximately 8,700 square miles (measured from Land Office 

map).

Gage. Friez automatic gage.

Control. Should be permanent, as station is at the lower end of a pool 600 feet long 

and just above rapids.

Discharge measurements. Made from car and cable.

Winter flow. Ice causes backwater and records are discontinued.

Diversions. Prior to July 1, 1912, there were adjudicated diversions of 58 secondfeet from the North Platte between Saratoga and the station above Pathfinder, 

and diversions of 1,270 second-feet from intervening tributaries.

Accuracy. Conditions are excellent, and the base data, which are all that are available, are reliable.

Cooperation. Station maintained in cooperation with the United States Reclamation Service.

The following discharge measurement was made by R. H. Fleteher: 

October 12. Gage height, 1.17 feet; discharge, 505 second-feet.

Daily gage height, in feet, of North Platte River above Pathfinder reservoir, Wyo.,for 1913.

PLATTE EIVEE BASIN. 215

NORTH PLATTE RIVER AT PATHFINDER, WYO.

Location. One-third mile south of Pathfinder, one-fourth mile below Pathfinder 

dam, and 800 feet below the mouth of the canyon, in sec. 24, T. 29 N., R. 84 W. 

The nearest tributary, Canyon Creek, enters 2 miles above.

Records available. May 9, 1905, to December 31, 1913.

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

Gage. Chain gage.

Control. Permanent.

Discharge measurements. Made from car and cable.

Winter flow. Ice causes slight backwater for short periods.

Regulation. The Pathfinder dam 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 records of inflow. These latter are based on evaporation losses, 

change of stage in the reservoir, and the outflow.

Diversions. Prior to July 1, 1912, there were adjudicated diversions of 279 secondfeet from tributaries entering the North Platte between the station above Pathfinder and this station. 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.

Cooperation. Records furnished by United States Reclamation Service.

Discharge measurements of North Platte River at Pathfinder, Wyo., in 1913.

NORTH PLATTE RIVER AND INTERSTATE CANAL AT WHALEN, WYO.

Location. At 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, 1913. These records represent

the discharge passing the overfall weir at Whalen and also amount of water passing

the headgates of the canal, which are located just above Whalen weir.
218 SUEPACE WATER SUPPLY, 1913, PART vi.

Drainage area. Not measured.

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

the weir crest. The discharge is then computed by a weir formula. There are 

also four sluice gates in the dam, through which the discharge is computed. In 

'the river, 75 feet downstream from the crest gage, is a second gage, with zero 10 

feet below that of the weir gage. The second gage is only used in computing the 

discharge through the gates when the openings are submerged. The discharge 

through the headgates of the canal is computed from the nine gate openings. A 

vertical staff located in the canal, 1,000 feet below the headgates, is used in computing the discharge when the headgate 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.

Regulation. The discharge represents chiefly 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 Wyoming-Nebraska line, exclusive of the diversion by United States Reclamation 

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

stations.

Cooperation. Records furnished by United States Reclamation Service.

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

for 1913.

PLATTE EIVEE BASIN. 221

NORTH PLATTE RIVER NEAR MITCHELL, NEBR.

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 that enters just below the station.

Records available. June 3,1901, to June 30,19i3. From May 29,1897, to October 

31, 1900, a station was maintained near Gehring. Though no tributaries enter 

between the two points, the records are not directly comparable during the irrigation season, as water is diverted for irrigation.

Drainage area. 24,400 square miles.

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

Control. Shifting since 1911.

Discharge measurements. Made from bridge.

Winter flow. River frozen over; observations discontinued.

Regulation. The Pathfinder reservoir of 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 to 75 second-feet from intervening tributaries.

Accuracy. No discharge measurements made during 1912; one measurement made 

in 1913 showed old rating curve no longer applicable; estimates of discharg^ not 

prepared.

Cooperation. The field data furnished by State engineer.

The following discharge measurement was made by Boden and Cass: 

April 8, 1913. Gage height, 2.95 feet; discharge, 2,850 second-feet.

Daily gage height, in feet, of North Platte River near Mitchell, Nebr.,for 1913.

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 records interrupted until October 15, 1910, when present 

gage, reading to a different datum, was placed in position.

PLATTE EIVEE NEAE COLUMBUS, NEBR.

, Location. At Meridian Bridge, 3 miles south of Columbus, OB line between sec. 36, 

T. 17 N., R. 1 W., and sec. 31, T. 17 N., R. 1 E., about 10 miles below mouth of 

Prairie Creek, and 5 miles above mouth of Loup River.

Records available. June 4, 1895, to December 31, 1913.

Drainage area. 56,900 square miles.

Gage. 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.

Control. Extremely shifting; at this point the river flows in the channels known as 

the main, middle, and south channels. The gage is in main channel.
224 SURFACE WATER SUPPLY, 1913, PART VI.

Discharge measurements. Made from bridges spanniBg each channel.

Winter flow. River freezes over; observations 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 

junction of the two branches and Columbus, and this diversion, together with the 

evaporation from the wide shallow channels, frequently causes the flow to cease 

at this point during the late summer and fall.

Accuracy. Results for 1913 should be fair.

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

the field data were furnished.

Nov. 23, from a well-defined rating curve; Nov. 24-28, from a curve based on one measurement. Discharge interpolated for days for which gage heights are missing. Observer records zero flow during July, 

August, and September. However, a discharge measurement of July 2 gives 40 second-feet, and there 

may have been a slight flow until July 10, when hydrographer found stream dry.

LAEAMIE RIVER NEAR JELM., WYO.

Location. At Boswell's ranch, in sec. 15, T. 12 N., R. 77 W., 4 miles south of Jelm 

post office, one-fourth mile below Colorado-Wyoming line.

Records available. May 7, 1911, to November 30, 1913. From June 22, 1904, to 

October 31, 1905, a station was maintained at Decker's ranch, one-half mile south 

of State line. The records at the two stations are practically comparable, as there 

are no tributaries nor diversions of any consequence between.

Drainage area. 365 square miles (Clason's 1911 sectional map of Colorado).

Gage. In 1911 an automatic recording gage was installed by the State engineer of 

Colorado. This is referred to same datum as the vertical staff used at first.

Control. Practically permanent.
PLATTE EIVEE BASIN. 235

Discharge measurements. Made from bridge at ordinary stages; low-water

measurements made by wading.

Winter flow. Ice causes backwater during winter months; records 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; estimates should be

excellent. 

Cooperation. Complete records furnished by State engineer of Colorado.

238 STTKFACE WATER SUPPLY, 1913, PAET VI.

SOUTH FOEK OF SOUTH PLATTE BIVER AT LAKE GEOKGE, COLO.

Location. At highway bridge in sec. 19, T. 12 S., R. 71 W., one-fourth mile below 

Lake George, in Pike national forest, about 2 miles above mouth of Caylor Gulch; 

no tributary between outlet of lake and the station.

Records available. October 22, 1910, to December 31, 1913.

Drainage area. Not measured.

Gage. Automatic recording gage installed in 1911, reading to the same datum as the 

original staff gage.

Control. A 2-foot timber-crib dam 50 feet below the gage.

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.

Regulation. The discharge at the station is controlled naturally to some extent 

by the dam at the outlet of Lake George. The lake has an area of one-half square 

mile and is used as an ice pond. It is controlled to a greater extent by Antero 

reservoir, located 45 miles upstream.

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

South Fork above Lake George. Besides these, Antero reservoir has a decree for 

storage of 85,600 acre-feet from the South Fork and tributaries. The Antero 

water all passes the Lake George station, as it is finally diverted from the South 

Platte. There are decrees for diversions of 1,926 second-feet from tributaries above 

Lake George.

Accuracy. Conditions favorable for accurate results; estimates.considered reliable.

Cooperation. Station maintained in cooperation with United States Forest Service 

and the State engineer.

SOUTH PLATTE EIVEE AT SOUTH PLATTE, COLO.

Location. In sec. 25, T. 7 S., R. 70 W., in Pike National Forest, three-quarters of a 

mile east of South Platte, about 300 feet below junction of North and South forks. 

No tributary enters between forks and station or for several miles below.

Records available. March 28, 1902, to December 31, 1913. 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 records from 1895 to 1898 were taken under direction 

of the Denver Power & Irrigation Co.

Drainage area. 2,610 square miles (measured from Hayden atlas).

Gage. An automatic recording gage installed by the State engineer March 14, 1910. 

From March 28, 1902, to May 7, 1905, the gage was at the highway bridge. On 

the latter date it was moved to its present site, 150 feet below. It is probable 

that the new gage read to a somewhat different datum. The recording gage is 

referred to datum of gage established in 1905.

Control. Practically permanent during 1913.

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.

Regulation. The flow is controlled to a certain extent by the Cheesman reservoir, 

which is situated on the South Fork about 20 miles above forks and has a capacity 

of approximately 80,000 acre-feet.

Diversions. No water js diverted between this station and that on the North Fork 

at South Platte. Between the station on the South Fork near Lake George and 

South Platte the Cheesman reservoir has a court decree for 80,000 acre-feet for 

municipal purposes. This water all passes the gaging station, as it is diverted 

from the South Platte farther downstream. There are decrees for diversions of 

1,400 second-feet from intervening tributaries and a reservoir decree for 46,000 

acre-feet.

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

Cooperation. Station maintained in cooperation with the State engineer.

Co. at Platte Canyon, decreased 1.4 per cent on account of the difference in drainage area.

SOUTH PLATTE RIVER AT DENVER, COLO.

Location. At the Sixteenth Street viaduct in Denver, 500 feet below mouth of 

Cherry Creek.

Becords available. May 7, 1895, to November 30, 1913.

Drainage area. 3,840 square miles.

Gage. Automatic recording gage installed August 12, 1909, and moved 100 feet 

upstream in April, 1913. 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 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 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.

Control. Shifting.

Discharge measurements. Made from the Fifteenth Street bridge during high 

water and by wading at low-water stages.

Winter flow. 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. Records since 1907 furnished by State engineer; considered only 

approximate for 1913. » » _. ,

SOUTH PLATTE RIVER NEAR KERSEY, COLO.

Location. At highway bridge in sec. 9, T. 5 N., R. 64 W., If miles north of Kersey, 

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

below mouth of Cache la Poudre River.

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

30, 1913.

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.

Control. Shifting.

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

wading at ordinary stages.

Winter flow. Ice causes slight backwater for a few days during the winter.

Diversions. Between this station and Denver there are court decrees for diversions 

of 3,764 second-feet from the South Platte and 17,000 second-feet from intervening 

tributaries, besides numerous flood-water decrees.

Accuracy. Measurements during 1913 inadequate for estimates of discharge; only 

base data available.

Cooperation. Records furnished by State engineer.

246 SURFACE WATER SUPPLY, 1913, PART VI.

SOUTH PLATTE RIVER AT JULESBURG, COLO.

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

R. 44 W. No important tributaries between station and Colorado-Nebraska State 

line, 1 mile distant. All tributaries for 100 miles or more above station are 

intermittent.

Records available. April 2, 1902, to November 16,1906; May 12,1908, to November 28, 1913.

Drainage area. 20,600 square miles.

Gage. When station was reestablished in 1908 it was located at new highway bridge, 

2,000 feet upstream from the original station. The datum of chain gage has 

remained unchanged since 1908.

Control. Shifting; frequent measurements required.

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

wading at low-water stages.

Winter flow. Ice causes backwater during winter months.

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 flood-water decrees. 

Between State line and the mouth diversions of 206 second-feet from the South 

Platte have been granted in Nebraska.

Accuracy. Sufficient measurements were not secured during 1913 to allow estimates 

to be made, and only base data are available.

Cooperation. Records for 1913 furnished by State engineer

Discharge measurements of South Platte River at Julesburg, Colo., in 1913.

NQTE. Gage moved 100 feet south on July 24; referred to correct datum. Old gage found to read 0.03 

feet high.

TARRYALL CREEK NEAR JEFFERSON, COLO.

Location. At Bobbins ranch, in sec. 6, T. 9 S., R. 74 W., about 10 miles southeast 

of Jefferson. Rock Creek enters half a mile below station.

Records available. June 27,1912, to December 4,1913. From October 18,1910, to 

June 28, 1911, a station was maintained within a quarter of a mile of this point, 

but the relation between the two gages is not known.

Drainage area. Not measured.

Gage. Vertical staff.

Control. Practically permanent.

Discharge measurements. Made by wading.

Winter flow. Ice causes severe backwater during winter months; records discontinued.

Diversions. There are court decrees for diversions of 314 second-feet from Tarryall 

Creek above the station and 220 second-feet below. The Tarryall Canal & Reservoir Co. has a provisional decree for storage of 68,000 acre-feet from Tarryall and 

tributaries above the station and a decree for a supply diversion amounting to 

450 second-feet. This diversion has not yet been made. The Boreas ditch diverts 

a small amount of water from headwaters of Blue River to Tarryall Creek at its 

headwaters. There are decrees for diversions of 926 second-feet from tributaries 

entering above the station.
248 SURFACE WATER SUPPLY, 1913, PAET VI.

Accuracy. Owing to the high altitude of the drainage basin (9,500 to 13,000 feet), 

alternate melting and freezing cause considerable diurnal fluctuations during the 

high-water period, and the mean daily gage based on morning and evening 

readings, as well as the maximum stage for the 24 hours, maybe somewhat in 

error. For that reason the estimates can not be considered better than good. 

Rating curve excellent.

Cooperation. Station maintained in cooperation with the Tarryall Canal & Reservoir Co.

NOETH FORK OF SOUTH PLATTE RIVER AT GRANT, COLO.

Location. At Grant post office, in sec. 9, T. 7 S., B. 74 W., in the Pike National

Forest, 250 feet above the mouth of Geneva Creek. 

Records available. July 18,1910, to December 31, 1913. 

Drainage area. 51 square miles (measured from Forest atlas). 

Gage. Vertical staff whose datum has remained unchanged. 

Control. Permanent during 1913. No backwater from Geneva Creek. 

Discharge measurements. Made from footbridge and by wading.
250 SURFACE WATQBE SUPPLY, 1913, PART VI.

Winter flow. Ice causes backwater during the winter months; measurements made 

to determine flow.

Diversions. There are court decrees for diversions of 5.5 second-feet from the North 

Fork above the station and diversions of 24 second-feet from tributaries entering 

above.

Accuracy. Owing to the high altitude of this station, considerable diurnal fluctuations at certain seasons of the year are likely to be caused by alternate melting 

and freezing, and the mean daily gage height based on one gage reading prior to 

October 1, 1913, may be considerably in error. This fact, together with the 

scattering gage heights, makes estimates at this station only fair during high-water 

period. Beginning October 1 the gage was read morning and evening and records 

for the last part of the year are good.

Cooperation. Station maintained in cooperation with United States Forest Service 

and State engineer.

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 November 30, 1913.

Drainage area. 128 square miles (measured from Forest atlas).

Gage. Chain gage, which replaced a vertical staff reading to same datum. On May 

23, 1913, the gage was moved 185 feet downstream and set to read the same as at 

the original site. Although the gage itself is below the headgates of the Cassell 

ditch in the present location, the measurements were all made above and, therefore, the flow represents that above the ditch, as the diversion is too small to have 

any appreciable effect on the gage heights.
SURFACE WATER SUPPLY, I9l3, PAR* Vf.

Control. Permanent at new site.

Discharge measurements. Made from bridge.

Winter flow. Ice causes backwater during winter months.

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, considerable diurnal fluctuations are likely to be caused at certain seasons of the year by alternate melting 

and freezing, and the mean daily gage height based on night and morning readings 

may be somewhat in error. For this reason the estimates can not be considered 

better than good. Rating curve excellent.

Cooperation. Gage heights furnished by State engineer.

NORTH FOEK OF SOUTH PLATTE EIVEE AT SOUTH PLATTE, COLO.

Location. One-third mile above South Platte. No tributary between station and

mouth. 

Records available. January 4, 1909, to September 30, 1910; April 1 to December

31, 1913.

Drainage area. 449 square miles (measured from Hayden atlas). 

Gage. Inclined staff. 

Control. Somewhat shifting.
254 SURFACE WATEE SUPPLY, 1913, PAET VI.

Discharge measurements. Made from car and cable during high and medium 

stages and by wading at low stages.

Winter flow. Ice causes backwater; discharge measurements made to determine 

winter flow.

Diversions. There are court decrees for diversions of 20 second-feet from North 

Fork between Cassells and South Platte and 60 second-feet from intervening tributaries. There are also a number of small ice and fish ponds which divert small 

amounts of water at various times.

Accuracy. Mean daily gage heights based on one observation and may be somewhat 

in error; estimates therefore can not be considered better than good.

Cooperation. Gage heights furnished by State engineer.

GENEVA CREEK AT GRANT, COLO.

Location. In the Pike National Forest, at highway 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 31, 1913. From July 5, 

1908, to November 3, 1911, a station was maintained at Sullivan's ranch, 3 miles 

above Grant. Except during the spring run-off, the flow at the two points ia 

practically the same.

Drainage area. 74 square miles (measured from Forest atlas).

Gage. Vertical staff.
256 STJBFACE WATER SUPPLY, 1913, PART VI.

Channel. Practically permanent during 1913.

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

at ordinary stages.

Winter flow. Ice causes backwater during the winter months; discharge measurements made to determine 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 acre-feet 

from Geneva and Kerby creeks.

Accuracy. Owing to the high altitude of this station considerable diurnal fluctuations are likely to be caused at certain seasons of the year by alternate melting 

and freezing; and the mean daily gage height based on morning and evening 

readings, together with the maximum gage height for the 24 hours; may be somewhat in error. For this reason the estimates can not be considered better than 

good.

Cooperation. Gage heights furnished by the State engineer.

relation to datum of original gage.

Control. Permanent during 1913.

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, considerable diurnal fluctuations are likely to be caused at certain seasons of the year by 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 and can be considered only fair.

Cooperation. Station maintained in cooperation with United States Forest Service

Discharge measurements of Scott Gomer Creek near Grant, Colo., in 1913.

Location. At Orodell station, in sec. 27, T. 1 N., R. 71 W., just below mouth of 

Fourmile Creek.

Records available. March 18, 1907, to December 31, 1913. From May 14, 1895, 

to December 20, 1909, a station was maintained about 1 mile below 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 lower station were published only in reports of the State engineer.

Drainage area. 108 square miles (State engineer's report).

Gage. Automatic recording gage owned by Colorado Power Co.

Control. Character not known, as only computed records are furnished.

Discharge measurements. Made from car and cable.

Winter flo-w. Ice causes backwater during the winter months; discharge measurements made to determine 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 

Colorado Power Co., by which records are furnished.

SOUTH BOULDER CREEK NEAR ROLLINSVILLE, COLO.

Location. At highway bridge in sec. 35, T. 1 S., R. 73 W., 1 mile west of Rollinsville 

in Pike National Forest. The nearest important tributary, Jennie Creek, enters 4 

miles above.

Records available. September 10, 1910, to December 31, 1913.

Drainage area. 39 square miles (measured from topographic sheets).

Gage. Vertical staff.

Control. Fairly permanent.

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

at ordinary stages.

Winter flow. Ice causes backwater.

Diversions. No court decrees for diversions above station; records probably represent the natural run-off.

Accuracy. Owing to the high altitude of the station, considerable diurnal fluctuation 

is likely to be caused at certain seasons by alternate melting and free zing, and 

the mean daily gage height based on one reading may be considerably in error. 

For this reason the estimates can not be considered better than fair.

Cooperation. Station maintained in cooperation with United States Forest Service.

Discharge measurements of South Boulder Creek near Rollinsville, Colo., in 1913.

Control. Character not known; only completed records furnished.

Discharge measurements. Made from car and cable.

Winter flow. Ice causes backwater during winter months and measurements are 

made to determine flow.

Diversions. There is a court decree for a diversion of 57 second-feet from Cache la 

Poudre River above station and decrees for diversions of 526 second-feet from tributaries entering above, including Wyoming diversions. Below 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 and 121 second-feet from headwaters 

of North Platte River to headwaters of Cache la Poudre through Chambers Lake. 

During 1913 a total of 15,220 acre-feet were diverted from the Laramie and 3,750 

acre-feet from the North Platte. From North Fork of Grand River there are 

decrees for a diversion of 525 second feet to headwaters of Cache la Poudre River. 

During 1913, 12,200 acre-feet were diverted.

Cooperation. From 1884 to 1901 the records were collected by Prof. L. G. Carpenter, 

of the Colorado State Agricultural College. Since 1910 records have been furnished by the State engineer, by whom the station is maintained.

LOUP RIVER AT COLUMBUS, NEBR.

Location. At railroad bridge in sec. 23, T. 17 N., R. 1W., at Columbus. No tributaries between station and mouth of the river, 3 miles below.

Records available. October 13,1894, to December 31,1913.

Drainage area. 13,500 square miles.

Gage. Vertical staff gage established at Union Pacific Hallway bridge November 23, 

1913. The original gage was a vertical staff situated a short distance above railroad 

bridge and was used from October 13, 1894, to June 24, 1904. On that date a 

chain gage was established on highway bridge, 1J miles downstream. The chain 

gage was set to read the same as original staff gage, but owing to the slope of the 

river the datum of the chain gage was 8.56 feet lower. The chain gage was used 

until November 21,1913.

Control. Extremely shifting.

Discharge measurements. Made from highway bridge and later from railroad 

bridge.

Winter flow. Ice causes backwater during winter months; observations 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 Paver above 

station. There were also approved diversions of 2,046 second-feet for irrigation 

and 3,130 second-feet for power from tributaries entering above.

Accuracy. Though the channel is extremely shifting, sufficient measurements have 

been made to insure fair estimates of discharge.

Cooperation. Field data for 1913 furnished by the State engineer.

. Discharge measurements of Loup River near Columbus, Nebr., in 1918.

282 StTEFACE WATER SUPPLY, 1913, PART VI.

Winter now. Ice causes backwater for only a short time during winter months. 

Regulation. The dam of the Fairbury roller mills, 2 miles above, may control the

flow to a certain extent during low-water season, causing a daily fluctuation.

The gage is read once each day. 

Diversions. Prior to September 1, 1912, there were approved diversions of 180

second-feet from the Little Blue above Fairbury, but none from the intervening

tributaries. There was no diversion from Little Blue Eiver below Fairbury. 

Accuracy. Estimates made by indirect method for shifting channels; considered

fair or possibly good. 

Cooperation. Field data furnished by State engineer.

Discharge measurements of Little Blue River near Fairbury, Nebr., in 1913.
