This is a digital copy of a book that was preserved for generations on library shelves before it was carefully scanned by Google as part of a project 
to make the world's books discoverable online. 

It has survived long enough for the copyright to expire and the book to enter the public domain. A public domain book is one that was never subject 
to copyright or whose legal copyright term has expired. Whether a book is in the public domain may vary country to country. Public domain books 
are our gateways to the past, representing a wealth of history, culture and knowledge that's often difficult to discover. 

Marks, notations and other marginalia present in the original volume will appear in this file - a reminder of this book's long journey from the 
publisher to a library and finally to you. 

Usage guidelines 

Google is proud to partner with libraries to digitize public domain materials and make them widely accessible. Public domain books belong to the 
public and we are merely their custodians. Nevertheless, this work is expensive, so in order to keep providing this resource, we have taken steps to 
prevent abuse by commercial parties, including placing technical restrictions on automated querying. 

We also ask that you: 

+ Make non-commercial use of the files We designed Google Book Search for use by individuals, and we request that you use these files for 
personal, non-commercial purposes. 

+ Refrain from automated querying Do not send automated queries of any sort to Google's system: If you are conducting research on machine 
translation, optical character recognition or other areas where access to a large amount of text is helpful, please contact us. We encourage the 
use of public domain materials for these purposes and may be able to help. 

+ Maintain attribution The Google "watermark" you see on each file is essential for informing people about this project and helping them find 
additional materials through Google Book Search. Please do not remove it. 

+ Keep it legal Whatever your use, remember that you are responsible for ensuring that what you are doing is legal. Do not assume that just 
because we believe a book is in the public domain for users in the United States, that the work is also in the public domain for users in other 
countries. Whether a book is still in copyright varies from country to country, and we can't offer guidance on whether any specific use of 
any specific book is allowed. Please do not assume that a book's appearance in Google Book Search means it can be used in any manner 
anywhere in the world. Copyright infringement liability can be quite severe.

• For the purpose of uniftxrmity in the presentation of reports, a general plan has been anead upon by the 
United States Reclamation Service, the united States Forest Service, the United StatesWeather Bureau, 
sod the United States Geological Survey, according to which the area of the United States has been divided 
into 12 parts, whose boundaries coincide with natural drainage lines indica t ed by the parts of the report. 

Ite data presented in these reports were collected by the United 
States Geological Survey xmder authority implied in the organic law 
(20 Stat. L., p. 394), which contains the following paragraph: 

Provided, That this officer [the Director] shall have the direction of the geological 
survey and the classification of public lands and examination of the geological struc- 
ture, mineral resources, and products of the national domain. 

The work was begun in 1888 in connection with special studies of 
water supply for irrigation. 

Since the fiscal year ending Jxme 30, 1895, successive sundry civil 
bills passed by Congress have carried the following item and appro- 
priations: 

For gaging the streams and determining the water supply of the United States and 
for the investigation of imdeiground currents and artesian wells and for the prepara- 
tion of reports upon the hest methods of utilizing the water resources.

SURFACE WATEB SUPPLY, 1911, PART VI. 



In the execution of the work many private and State organizations 
have cooperated. Acknowledgments for such cooperation are made 
on pages 13-14, and also in connection with the description of each 
station affected by the cooperative work. 

PUBLICATIONS. 

Measurements of stream flow have been made at nearly 2,000 
points in the United States, and also at many points in small areas 
in Seward Peninsula and the Yukon-Tanana region, Alaska, and in 
the Hawaiian Islands. During 1911 gaging stations were maintained 
by the Survey and the cooperating organizations at about 1,500 points 
in the United States, and many discharge measurements were made 
at other points. In connection with this work data were also col- 
lected in regard to precipitation, evaporation, storage reservoirs, 
river profiles, and water power in many sections of the country, 
and will be made available in the regular surface water supply papers 
from time to time. A complete Ust of the gaging stations maintained 
by the Survey to and including 1910, and a list of the papers relating 
to the water supply of the country, have been pubUshed by the Survey 
as Water-supply Paper 280. An index to the reports containing 
stream-flow measurements prior to 1904 has been published as Water- 
Supply Paper 119. 

For each calendar year there has been prepared a report embody- 
ing the stream-flow data collected during that year, which has been 
published either as a part of the Annual Report of the Director, as a 
bulletin, or as a water-supply paper, as shown by the following table:

XoTK.— No data regarding stream flow are given in the 15th and 17th annual reports. 

The table which follows gives, by years and drainage basins, the 
numbers of the papers on surface water supply published from 1899 
to 1911. The data for any particular station will be found in the 
reports covering the years during which the station was maintained. 
For example, data for Machias River at Whitneyville, Me., 1903 to 
1911, are published b Water-Supply Papers 97, 124, 165, 201, 241, 
261, 281, and .301, which contain records for the New England 
streams from 1903 to 1911.

DEFINITION OF TERMS. 

The volume of water flowing in a stream — the "run-off" or "dis- 
charge'' — ^13 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 second- 
feet, gallons per minute, miner's inches, and discharge in second-feet 
per square mile, and (2) those which represent the actual quantity of 
water, as run-off in depth in inches and acre-feet. "The units used in 
this series of reports are second-feet, second-feet per square mile, run- 
off depth in inches and acre-feet. They may be defined as follows: 

"Second-foot" is an abbreviation for cubic foot per second and is 
the unit for the rate of discharge of water flowing in a stream 1 foot 
wide, 1 foot deep, at a rate of 1 foot per second. It is generally used 
as a fundamental unit from which others are computed by the use of 
the factors given in the following table of equivalents. 

'* Second-feet per square mile" is the average number of cubic feet 
of water flowing per second from each square mile of area drained, on 
the assumption that the run-off is distributed uniformly both as 
regards time and area. 

'* Run-off, depth in inches," is the depth to which the drainage area 
would be covered if all the water flowing from it in a given period 
were conserved and uniformly distributed on the surface. It is used 
for comparing run-off with rainfall, which is usually expressed in 
depth in inches. 

An ' ' acre-foot " is equivalent to 43,560 cubic feet Mid is the quantity 
required to cover an acre to the depth of 1 foot. The term is com- 
monly used in connection with storage for irrigation work.

EXPLANATION OF DATA. 

For each regular current-meter gaging station the following data, 
so far as available, are given: Description of the station, list of dis- 
charge measurements, table of daily gage heights, table of daily 
discharge, table of monthly and yearly discharges and run-oflF. For 
stations located at weirs or dams the gage-height table is omitted. 

In addition to statements regarding the location and installation 
of current-meter stations, the descriptions give information in regard 
to any conditions which may affect the constancy of the relation of 
gage height to discharge, covering such points as ice, logging, shift- 
ing channels, and backwater; also information regarding diversions 
which decrease the total flow at the measuring section. Statements 
are also made regarding the accuracy and rehability of the data. 

The table of daily gage heights records the daily fluctuations of the 
surface of the river as found from the mean of the gage readings taken 
each day, usually in the morning and in the evening. The gage 
height given in the table represents the elevation of the surface of 
the water above the zero of the gage. All gage heights affected by 
the presence of ice in the streams or by backwater from obstructions 
are published as recorded, with suitable footnotes. The rating table 
is not appUcable for such periods unless the proper corrections to the 
gage heights are known and applied. Attention is called to the fact

EXPLANATTON OP DATA. 15 

that the zero of the gage is placed at an arbitrary datum and has no 
relation to zero flow or the bottom of the river. In general, the zero 
is located somewhat below the lowest known flow, so that negative 
readings shall not occur. 

The discharge measurements and gage heights are the base data 
from which rating tables, daily discharge tables, and monthly dis- 
charge tables are computed. 

The rating table gives, either directly or by interpolation, the dig- 
charge in second-feet corresponding to every stage of the river recorded 
during the period for which it is applicable. It is not published in 
this report, but can be determined from the tables of daily gage 
heights and daily discharge as follows: 

First plot the discharge measurements for the current and earlier 
years on cross-section paper, with gage heights in feet as ordinates 
and discharge in second-feet as abscissas. Then tabulate a number 
of gage heights taken from the daily gage-height table for the com- 
plete range of stage given and the corresponding discharges for the 
days selected from the daily discharge table and plot the values on 
cross-section paper. The last points plotted will define the rating 
curve used and will lie among the plotted discharge measurements. 
After drawing the rating curve, a table can be developed by scaling 
off the dischai^e in second-feet for each tenth foot of gage height. 
These values should be so adjusted that the first differences shall 
always be increasing or constant, except for known backwater 
periods. 

The table of daily discharge gives the discharge in second-feet 
corresponding to the observed gage heights as determined from the 
rating tables. 

In the table of monthly discharge the column headed '* Maximum" 
gives the mean flow, as determined from the rating table, for the day 
when the mean gage height was highest. As the gage height is the 
mean for the day, it does not indicate correctly the stage when the 
water surface was at crest height, and the corresponding discharge 
was consequently larger than given in the maximum column. Like- 
wise, in the column of "Minimum" the quantity given is the mean 
flow for the day when the mean gage height was lowest. The col- 
umn headed ''Mean" is the average flow in cubic feet for each second 
during the month. On this the computations for the remaining 
colunms, which are defined on page 12, are based. 

The field methods used in the collection of the data presented in 
this series of reports are described in the introductory sections of 
Water-Supply Papers 261 to 272, inclusive, ''Surface water supply 
of the United States, 1909." Plates I and II show the average pre- 
cipitation and run-off in the United States as determined from the 
measurements of stream flow made by the Geological Survey and

records of rainfall collected by the Weatiier Bureau; Plate III shows 
typical gaging stations; Plate IV shows current meters ^ used in the 
work. 

ACCURACY AND RELIABIIiITT OF FTET»D DATA AND 
COMPARATIVE RESULTS. 

The accuracy of stream-flow data depends primarily on the natural 
conditions at the gaging station and on the methods and care with 
which the data are collected. Errors of the first group depend on 
the degree of permanency of channel and of permanency of the rela- 
tion between discharge and stage. 

Errors of the second class are due, first, to errors in observation of 
stage; second, to errors in measurements of flow; and, third, to errors 
due to misinterpretation of sti^ and flow data. 

In order to give engineers and others information regarding the 
probable accuracy of the computed results, footnotes are added to the 
daily discharge tables, stating the probable accuracy of the rating 
tables used, and an accuracy column is inserted in the monthly dis- 
charge table. For the rating tables 'Veil defined" indicates, in 
general, that the rating is probably accurate within 5 per cent; 
"fairly well defined," within 10 per cent; '^poorly defined" or "ap- 
proximate" 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, tlie 
probable reliability of the observer, and knowledge of local condi- 
tions. In this column A indicates that the mean monthly flow is 
probably accurate within 5 per cent; B, within 10 per cent; C, within 
16 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 dis- 
tricts or omitting estimates of water diverted for irrigation or other 
use, and they should therefore be considered as only approximate, 
particularly for periods of irrigation or of low water. For these 
errors it is as a rule not feasible to make adequate correction. 

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

any engineer the means of examining and adjusting to his own needs 
the results of the computations. The table of monthly discharge is so 
arranged as to give only a general idea of the flow at the station and 
should not be used for other than preKminary estimates. The deter- 
minations 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 pre- 
sented in these papers should verify all ratings and make such 
adjustments for earlier years as may seem necessary. 

COOPERATION AND ASSISTANCE. 
MONTANA. 

Much of the work in Montana has been carried on under cooperative 
agreement with the United States Reclamation Service, the work 
being done by the Geological Survey and the expense borne by the 
Reclamation Service. 

The State of Montana also cooperated in the work, authority hav* 
ing been granted by the State legislature in 1911, which passed a 
bill appropriating $3,000 for 1911 and $3,000 for 1912, to be expended 
on the work of gapng streams, in accordance with paragraph 3, 
section 2244, of the Revised Codes of 1907 of the State of Montana, 
which reads bs follows: 

The State engineer shall become conversant with the waterways of the State and 
the needs of the State as to irrigation matters; shali make, or cause to be made, measure- 
ments 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 Mon- 
tana Exx>eriment Station; such measurements to be made on streams in order of their 
importance, provided that measurements already made, if deemed reliable, may be 
adopted. 

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

A number of stations in the western part of Montana were main- 
tained in cooperation with the Forest Service. 

Acknowledgments are due to the several Carey Land Act com- 
panies for salaries of gage observers paid during the year; to the 
United Missouri River Power Co., for records on Missouri River; to 
the Glass-Lindsay Land Co., for gage observers' salaries at several 
stations; and to George E. Baker, for gage heights and discharge 
measurements on Pipestone and Whitehall creeks. 

COLORADO. 

The work in Colorado was carried on in cooperation as follows: 
The United States Forest Service furnished the services of a 

hydrographer for measuring the streams on the national forests and 

also furnished the gage heights.

two stations on the Cache la Poudre. 

WYOMma. 

The work in Wyoming was carried on in cooperation as foUows : 

Mr. A. J. Parshall, State engineer, paid half the field expense of 
maintaining most of the Wyoming stations and also paid the gage 
observers. He also arranged for cooperation with a number of indi- 
viduals interested in the different records. 

The United States Forest Service furnished the services of a 
hydrographer during the latter part of the year for measuring the 
streams on the national forests and also furnished the gage heights. 

The United States Reclamation Service furnished the completed 
records on the North Platte at Pathfinder and Whalen and gage 
heights and gate openings on the Shoshone at Corbett dam. 

NEBRASKA. 

The work in Nebraska was carried on in cooperation with Mr. I). D. 
Price, State engineer, who furnished all the field data.

APPROPRIATION OP WATER. 

VABIATIOlf 8 m STATB WATEB LAWS. 

The water laws of the Western States differ so widely in their 
provisions that such terms as "water filing/' "appropriation," and 
"water right'' have no general application or meaning. The rights 
to water in these States rest in general, first, on the Constitution and 
statutes of the United States; second, on the respective State con- 
stitutions and the State statutes that have been enacted in accord- 
ance therewith; third, on tlie decisions of Federal and State courts 
in the interpretation of these various provisions of law and in their 
application to specific conditions; and, fourth, on the requirements 
of the State engineers and other officials charged with the adminis- 
tration of the State water laws. 

In addition, the right to convey water acioss public lands must 
be acquired in accordance with the provisions of the acts of Congress 
and the regulations of the Secretary of the Interior and the Secretary 
of Agriculture pursuant thereto. 

In this report each description of a gaging station in Colorado 
gives the number of second-feet of adjudicated diversions from the 
stream and its tributaries, to indicate as nearly as possible the extent 
to which appropriations have been recognized by the State courts. 
It does not follow, however, that this amount of water is actually 
diverted, as many of the older decrees called for amounts greatly in 
excess of those actually used; on the other hand, no account lias 
been taken of filings which have not yet been perfected and adjudi- 
cated. It is impossible from the State records to reach any conclu- 
sion as to the validity of these filings or as to the probability of their 
final perfection. 

CONSTmmOlTAL PROVISIONS. 

COLORADO. 

In comjnon with most of the other Western States, Colorado has 
discarded the common-law doctrine of riparian rights and has estab- 
lished a system based upon prior appropriation. The following are 
extracts from the State constitution relative to the use of water for 

irrigation: 

Article XVI. 

IRRIGATION. 

Sec. 5. The water of every natural stream not heretofore appropriated within the 
State of Colorado is hereby declared to be the property of the public; and the same is 
dedicated to the uae of the people of the State, subject to appropriation as hereinafter 
provided. 

Sbc. 6. The right to divert the unappropriated waters of any natural stream to 
beneficial usee shall never be denied. Priority of appropriation shall give the better 
right as between those using the water for the same purpose; but when the waters of 
any natural stream are not sufficient for the service of all those desiring the use of the

flame, those using the water for domestic purposes shall have the preference over those 
^claiming for any other purpose, and those using the water for agricultural purposes 
shall have preference over those using the same for manufacturing purposes. 

Sec. 7. AH persons and corporations shall have the right of way across public, 
private, and corporate lands for the construction of ditches, canals, and flumes for the 
purpose of conveying water for domestic purposes, for the irrigation of agricultural 
lands, and for mining and manufacturing piu^oscs, and for drainage, upon payment 
of just compensation . 

Sec. 8. The general assembly shall provide by law that the board of coimty com- 
missioners, in their respective counties, shall have power, when application is made 
to them by either party interested, to establish reasonable maximum rates to be chaiged 
for the use of water, whether furnished by individuals or corporations. 

WYOMING. 

In Wyoming, as in Colorado, the courts reject riparian rights and 
the principal of prior appropriation is established in the State. The 
provisions of the State constitution regarding the appropriation and 
use of water are as follows: 

Article I. 

Sec 31. Water being essential to industrial prosperity, of limited amount, and easy 
of diversion from its natural channels, its control must be in the State, which, in 
providing lor its iise, shall equally guard all the varied interests involved. 

Abticle VII T. 

□tBIGATION AND WATER RIGHTS. 

Sec. 1. l^e water o! all natural streams, springs, lakes, or other collection of still 
water within the boundaries of the State, are hereby declared to be the property of 
the State. 

Sec. 2. There shall be constituted a board of control, to be composed of the State 
engineer and superintendents of the water divisions, which shall under such regulat ions 
as may be prescribed by law, have the supervision of the waters of the State and of 
their appropriation, distribution, and diversion and of the various officers connected 
therewitii. Its decisions to be subject to review by the courts of the State. 

Sec. 3. Priority of appropriation for beneficial uses shall give the better right. No 
appropriation shall be denied except when such denial is demanded by the public 
interests. 

Sec 4. The legislating shall by law divide the State into four (4) water divisions 
and provide for the appointment of superintendents thereof. 

Sec 5. There shall be a State engineer who shall be appointe<l by the governor of 
the State and confirmed by the senate; he shall hold his office for the term of six (6) 
years or until his successor shall have been appointed and shall have qualified. He 
shall be president of the board of control and shall have general supervision of the 
waters of the State and of the officers connected with its distribution. No person 
shall be appointed to this position who has not such theoretical knowledge and such 
practical experience and skill as shall fit him for the position. * 

Article XIII. 

Sec. 5. Municipal corporations shall have the same right as individuals to acquire 
rights by prior appropriation and otherwise to the use of water for domestic and 
municipal purposes, and the legislature shall provide by law for the exercise upon 
the part of incorporated cities, towns, and villages of the right of eminent domain 
for the purpose of acquiring from prior appropriators upon the payment of just com- 
l)onsation, such water as may be necessary for the well being thereof and for domestic

APPROPRIATION OF WATER. 21 

MONTANA. 

The following provisioii in the Montana State constitution relates 
ta the use of the water in the State: 

[Art. 2, sec. 15.] The use of all water now appropriated, or that may hereafter be 
appropriated for sale, rental, distribution, or other beneficial use, and the right of way 
over the lands of others for all ditches, drains, flumes, canals, and aqueducts, nece:;- 
sarily used in connection therewith, as well as the sites for reservoirs necessary for 
coUecting and storing the same, shall be held to be a public use. 

NORTH DAKOTA. 

The sole provision of the State constitution of North Dakota rela- 
tive to the use of water is the following: 

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

SOUTH DAKOTA. 

This State has no constitutional provisions relative to tlie use of 
water. 

NEBRASKA. 

The State constitution of Nebraska makes no provision for the use 
of water in the State. 

ADMINISTBATION OF WATER LAWS. 
COLORADO. 

Appropriation of water in Colorado may be divided into two gen- 
eral classes: The direct appropriation, where the water is used as 
delivered from the head gates of the canal, and the appropriation for 
storage, where water from the river is not used at the time of diver- 
sion but is stored in reservoirs for future use. Appropriations of the 
second class are usually valid only during periods of high water when 
there is an excess of water over the ne«ds of the direct appropriators. 
In the construction of reservoirs it is necessary to obtain approval of 
plans by the proper county commissioners, in addition to obtaining, 
that of the State engineer, for all dams exceeding 10 feet in height. 
The entire construction of the reservoir is imder the supervision of 
the State engineer, who has authority to require material used and 
work of construction to be done to his satisfaction. In case of failure 
of a reservoir the owners are Uable for aU ensuing damages. 

The control of water by the State is vested in the State engineer, 
whose duty it is to supervise the diversion of water by the various 
appropriators in accordance with the decrees of the State courts. 
TTie State is divided into five irrigation divisions, each in charge of a 
division engineer, who is imder the direction of the State engineer. 
Each irrigation division is divided into a number of water districts, 
of which there are 70 for the entire State. For each water district 



Digitized by LjOOQ IC 



22 SUKFACE WATER SUPPLY, 1911, PART VI. 

there is appointed a water commissioner, whose duty it is, under Uio 
supervision of the division engineer, to divide the water in the 
natural streams among the several ditches taking water from the 
same, according to the rights of each. Whenever there is a scarcity 
of water he is empowered to shut down the head gates of those 
ditches whose priorities are of too recent date to entitle them to 
divert water. In the discharge of tliis duty he has the power of a 
constable. 

WYOMING. 

The constitution of the State of Wyoming creates the office of 
State engineer and divides the State into four principal water divi- 
sions, each under the control of a division superintendent. The 
State engineer and the division superintendents form a board of con- 
trol having supervision of the appropriation and distribution of the 
water, subject to court review. 

Rights to the use of water are begim by filing an application in 
the office of the State engineer. This application must be prepared 
m accordance with the State law and the requirements of the State 
engineer. When the application is in proper form a permit to divert 
the water and construct the works is issued. 

The distribution of the water in accordance with the respective 
rights of permittees is supervised by water conmiissioners, one hav- 
ing jurisdiction in each of a large number of water districts, into 
which the four principal divisions are divided. The acts of the com- 
missioners of any district are subject to review by the higher admin- 
istrative officials, and eventually by the courts. 

MONTANA. 

An appropriation of water in Montana is begun by the posting of 
a notice at the proposed point of diversion, a copy of which notice 
is filed with the county clerk and recorder of the county in which the 
water is to be diverted. There is no limitation as to the amount of 
water upon which any person may file, and many streams have single 
filings upon them for more than their entire flow. Eventually, how- 
ever, each appropriator can acquire the right to use only such water 
as he has put to beneficial use. Questions arising as to the rights of 
appropriators are determined by court proceedings. The State en- 
gineer has no functions relative to the diversion or distribution of 
water, but the State courts may appoint commissioners to enforce 
decrees. 

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

NORTH DAKOTA. 

General supervision of matters relating to the use of water is vested 
in the State engineer, who is particularly charged with the custody 



Digitized by LjOOQ IC 



APPBOPRIATION OF WATER. 23 

of records and the survey of streams. The State is divided into four 
water divisions, each in charge of a commissioner^ and each division 
may be further subdivided into districts, each having a water master. 
The water commissioners; together with the State engineer, constitute 
a board empowered to make general rules for the control of water. 

Appropriations made prior to the present water law are adjudicated 
by the courts, one copy of the decree being filed in the office of the 
State engineer. Applications to appropriate water are filed with the 
State engineer, the procedure therefor being similar to that in 
Wyoming. 

NEBRASKA. 

Control of water for irrigation is vested in the State board of irri- 
gation, highways, and drainage, which consists of the governor, 
attorney general, and commissioner of public lands. The State 
engineer is appointed by the board, and acts as its secretary. The 
State is divided into two water divisions, each in charge of a superin- 
tendent. Within these divisions water districts, in charge of water 
conimissioneTs, may be created as needed. The water commissioners 
control the distribution of water to the respective appropriators. 

Applications to appropriate water for irrigation are made to the 
State board in accordance with the regulations. Upon approval the 
applicant may construct the necessary works. A certificate is finally 
issued by the State board and recorded with the county clerk. 

Storage reservoirs are subject to special provisions of law, and dams 
over 10 feet high must be authorized by the board. 

IBBIGATION DI8TBICT8. 

With the growth of irrigation in Colorado it has become necessary 
to enact laws creating irrigation districts whereby the owners of 
adjacent lands may organize for the purpose of jointly conveying 
^ater to irrigate these lands. When a majority of landowners in a 
district desire to irrigate their lands, they may petition the county 
commissioners of the county in which the greatest acreage of land is 
located to organize an irrigation district. An election is then held 
by the commissioners at which all the landowners in the proposed 
district are entitled to vote on the question of organization. If the 
result of the election favors it, the irrigation district is organized and 
a board of three directors elected. This board is empowered to enter 
into contracts for completing the necessary structiu'es to irrigate the 
lands, and to acquire rights of way, water rights, etc. Similar statutes 
have been enacted in Wyoming, Montana, and Nebraska. 

TBJBt CABEY ACT. 

The act of August 18, 1894 (28 Stat., 372, 422), commonly known 
as the Carey Act, and amendments thereto, the purpose of which is 
to aid the public-land States in the reclamation of the desert lands 



Digitized by LjOOQ IC 



24 SURFACE WATER SUPPLY, 1911, PART VI, 

therein and in the settlement, cultivation, and sale of such lands in 
small tracts to actual settlers, authorize — 

(a) The temporary withdrawal of public lands from settlement or 
entry pending investigation and survey preliminary to the filing of 
an application for segregation, such withdrawn lands to be restored 
to settlement and entry at the end of one year from the date of 
withdrawal in case application for segregation is not theretofore 
made. 

(b) The segregation of public lands by the Secretary of the Inte- 
rior, contracts between the United States and any beneficiary State, 
and the reclamation of such lands by beneficiary States within 10 
years from the approval of the State's application (subject to an 
extension of five years). 

(c) The patenting to any beneficiary State of any tract of reclaimed 
land when satisfactory proof is made that an ample supply of water 
to reclaim it is actuaUy furnished. 

The usual procedure imder the Carey Act is about as follows: 
A corporation or individual applies to the State for the withdrawal 
of certain public lands proposed for irrigation. The State thereupon 
submits to the Interior Department an application for their with- 
drawal. On the approval of this application the State is allowed one 
year in which to investigate the project and prepare satisfactory 
plans for reclamation. The proposing company conducts the inves- 
tigation and, if a project that is considered feasible is developed, 
makes application to the State for the segregation of the irrigable 
lands and offers to contract witlx the State for their reclamation. 
The State thereupon applies to the Interior Department for the 
segregation of the lands under the terms of the Carey Act and its 
amendments. If the plan of irrigation is found to be feasible, the 
irrigation company responsible, and the available water supply 
adequate, the lands are segregated and the contract for their recla- 
mation is entered into between the United States and the State. 
When the irrigation works are completed to the satisfaction of the 
Government, patent is issued to tho State or to its assigns. The 
State receives payment for the lands from the settler, and the irriga- 
tion company, either directly or through the State, receives payment 
from each settler for his proportionate share of the irrigation works 
and water rights involved. 

The Tenth General Assembly of Colorado, by an act approved 
March 15, 1895, accepted the conditions and grants of land to the 
State under the provisions of the Carey Act. The subsequent State 
laws stipulate that the selection, management, and disposal of such 
lands shall be vested in the State board of land commissioners. 
Before a project is approved the engineering features must be passed 
upon by the State engineer. Similar statutes have been enacted by 
Wyoming and Montana.

RED ROCK RIVER AT LIMA, MONT. 

Location. — Near the deed ranch, 1 mile east of Lima, Mont. Principal tributaries 
below the station, Sheep and Sage creeks. 

Becords' available.— August 14, 1907, to September 30, 1911. 

Drainage area. — Not measured. 

Gage. — Chain; installed October 27, 1908, at a point just above the cable and 300 
feet farther downstream than the old sta£f gage which it replaced; datum of chain 
gage not the same as that of the staff gage. 

Channel. — ^Probably permanent. 

Diacharge measurements. — ^At ordinary and high-water stages made from a cable 
below the gage; at extremely low stages measurements made by wading just below 
the cable section. 

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

Diversions. — ^Three ditches, each carrying approximately 900 miner's inches, take 
water from Red Rock above the station. The flow of water above the station is 
all appropriated, but the rights are unadjudicated. 

Storage. — ^The dam of the reservoir storing the water of the Red Rock has been 
completed, but no canals have been built. The dam is of earth with concrete 
core, is 50 feet high, and will impound 90,000 acre-feet; its top elevation is 6,700 
feet; the dam is 16 miles above Lima, Mont., and 27 miles below lower Red Hock 
Lake. 

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

Discharge measurements of Red Rock River at Limn, Mont., 1911.

BEAVERHEAD RIVER AT BARRATTS, MONT. 

Location. — One mile above Barratte and 2 miles south west of Dillon, Mont., in the 
SW. i SW. i sec. 20, T. 8 S., R. 9 W. 

BecordB available.— August 12, 1907, to December 31, 1911. 

Drainage area. — Not measured. 

Gage. — ^A standard chain gage was installed on the downstream side of the bridge 
June 22, 1908, to replace the ordinary sta£f gage which had previously been used; 
datum of chain gage the same as that of the staff gage. 

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

Discharge measurements. — Made from downstream side of the bridge. 

Winter fiow. — Stream remains open during the winter months. 

Diversions. — Innumerable diversions are made above the station. Decreed water 
rights, aggregating 85,866 inches of water, are filed on from Lima on Red Rock 
River to a point 10 miles above Twin Bridges. The three largest canals diverted 
below the station are Canyon Creek canal, appropriating 6,000 inches; Union 
canal, appropriating 4,000 inches; and Beaverhead canal, diverted just north of 
Dillon, appropriating 5,000 inches. The Union Electric Co., of Dillon, has a 
canal with a carrying capacity of 6,000 inches. 

Beaverhead River is called Red Rock River from its source in Red Rock I>akes 
to the post office of Red Rock, below which it is called the Beaverhead. The prin- 
cipal tributaries to the Beaverhead above the station are Grasshopper Creek, 12 miles 
south of Dillon; Horse Prairie Creek, 20 miles south; and Rattlesnake and Blacktail 
Deer creeks. Irrigation has probably been practiced in Beaverhead Valley longer 
than in any other valley in Montana, ditches constructed in the early seventies being 
still in operation.

SUBFAOE WATEB SUPPLY, 1911, PABT VL 



MISSOURI BIVEB AT CASCADE; MONT. 

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

the east side of the town of Cascade, Mont. 
Becords available.—July 20, 1902, to December 31, 1911. 
Drainage area. — 18,300 square miles. 

Qage. — Standard chain gage attached to the bridge; datum unchanged. 
Channel. — Probably permanent except at extreme flood stages. 
Discharge meaauremente. — ^Made from lower side of bridge. 
Winter flow.— Affected by ice. 

The most important tributaries between this station and the station at Toston, 
above, are Dearborn River, Little Prickly Pear Creek, and Prickly Pear Creek. 
Although irrigation is extensively practiced in the Missouri River valley, the water 
is taken from the tributary streams, the Missouri itself because of its high banks and 
great variation in flow and difficulty of diversion being little used. 

Discharge measurements of Missouri River at Cascade, Mont., in 1911.

SUBPAOE WATER SUPPLY, 1»11, PABT VI. 



Oage.— Staff; on left bank directly south of observer's house. A new gage was set 
October 12, 1910, at the original site but at a datum 1.0 foot lower than that prev- 
iously used. All gage heights for 1910 were reduced to new datum. 

ChaaneL — Gravelly, unclean, and shifting. 

]>^acharge xneasurements.— Made by wading.

mining. At present the creek furnishes some water for irrigation, but the valley 
is naiTow and affords but little irrigable land. The normal flow of the stieam is 
appropriated. 

Accuracy. — ^Data not entirely satisfoctory; no flood records have been obtained.

FALLS CREEK HEAR CLEMOITS, MONT. 

Location. — ^At a point 1} miles above ClemonB, Mont., 500 feet above the mouth, of 
the creek. 

Records available. — May 4, 1908, to December 31, 1911; fragmentary because of ttie 
great distance the observer lives from the gage. 

Drainage area. — Not measured. 

Gage. — Staff; datum unchanged. 

Channel. — Permanent except in flood. 

Discharge measurements. — ^Made by wading or from a cable. 

Winter flow. — ^Affected by ice. 

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

Accuracy. — ^Interpolations between observed gage heights believed to be fairly accu- 
rate. 

Falls Creek affords opportunities for water power development above the station, as 
its fall is large.

TWO MSDIOUTE BIVIB AT FAKILT, MOVT. 

Location.— In the NE. } NE. } sec. 2, T. 31 N., R. 9 W., at the Holy Family Miaeion, 
16 miles southeast of Browning, Mont., and about 6 miles above the mouth of 
Badger Creek, the nearest tributary. 

Becorda available.— April, 1907, to December 31, 1911. 

Drainage area. — 368 square miles. 

Gage.— Standard chain on the east bank of the stream directly back of the Mission 
buildings; datum of gage was lowered 0.95 foot July 21, 1908. 

Channel.— Gravel . 

Discharge measurements. — Low- water measurements made by wading at section 
near the gage; high- water measurements must be made from the old wagon bridge 
about 3 miles above the Mission. 

Winter flow.— Affected by ice. 

Diversions and storage.— Water is diverted at a point about 2 miles above the 
gage by a ditch which supplies water for about 100 acres of land on the farm at the 
Holy Family Mission. The United States Reclamation Service has under con- 
struction a project which will use about 200 second-feet of water for irrigating land 
north of the stream for the Blackfeet Indians. The water will be diverted near 
the mouth of Little Badger Creek, a small tributary entering from the south above 
the station. A storage reservoir will be built at Two Medicine Lake near the 
headwaters of the stream to augment the low-water flow. 

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

Drainage area.— 224 square miles. 
Gage.— Chain. The original'staf! 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 wadied out on May 25, 1909, and was reset at a different datum 

and 400 feet below the old Piegan Mission crossing. 
ChaaneL— Two chamiels at both medium and low stages; at high stages the stream 

flows in several channels. 
Biaeharge measurementa. — ^High-water measurements made from a cable 4 milee 

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

above the gage. 
Divenlons.— The United States I^clamation 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. 
Aocoracy. — High-water measurementa are only &ir; low-water records are, however, 

good.

DUPUYEB CRBXK AT DTTPirYBB. MOVT. 

Location.— In SW. i SW. i aec. 10, T. 28 N., R. 7 W., at the highway bridge in the 
town of Dupuyer, Mont. 

RecoTdfl available.— April 15, 1908, to December 31, 1911. 

Drainage area. — Not measured. 

Gage. — The original staff gage was nailed to the cribbing under the eaeit end of the 
highway bridge. The gage was washed out July 28, 1909, and was replaced 
September 20, 1909, gage readings being reduced to the original datum. In the 
Bprii^ of 1909 a breakwater was constructed on the left (west) bank which deflected 
the water to the opposite site. A new gage was installed April 25, 1910, at the 
same site and the original datum, but owing to changes in the channel, the gage 
records for 1910 and 1911 are not directly comparable with those for earlier years. 

Channel. — Shifts at high stages. 

Discharge meaaurements. — Made from downstream side of highway bridge at 
high stages; low-stage measurements are made by wading. 

Winter flow. — Affected by ice. 

Accuracy. — Frequent measurements are necessary at this station to insure good results 
as conditions in the channel are unfavorable.

TXTOV BZVZ& AT BT&ABAVS.i MONT. 

Location.^In the 8E. i NE. i eec. 35, T. 25 N., R 7 W., I mile north of Peeble's 
ranch, 16 miles above Chouteau, Mont., at Strabane poet office. 

Records available.— November 26, 1904, to December 31, 1906; January 16, 1908, 
to December 31, 1911. 

Draina^ area. — 140 equare miles. 

Qage. — ^The original gage was spiked to a post on the left bank about 40 feet above the 
bend of Kroff's irrigation ditch. On March 9, 1905, it was moved by the observer 
to a point 250 feet upstream to avoid the effect of the dam erected at the head of 
the ditch below. On May 8, 1905, the gage was referred to the bench marks and 
it wae found that the datum had been raised 0.7 foot in moving; the difference 
between the level of the water surface at the old site and that at the new was 0.20 
foot; on May 8, 1906, the gage was again moved 1) miles upstream to Mr. Bjom- 
stad's ranch and set at an entirely different datum. The station was discon- 
tinued during 1907, and when it was reestablished in 1908 a standard chain gage 
was installed on the left bank. On March 23, 1911, a new station was established 
one-half mile downstream from old gage. 

ChaaneL — Shifts at high stages; current swift. 

Diaeharge 2neaaurenienta.—At flood stages, made from cable one-fourth mile above 
the gage; at low stages, by wading at various sections. 

Winter flow. — ^Not affected by ice. 

Diveniozi8 and atorage. — PtacticaUy no water is diverted above the station, but 
the ordinary flow below the station is appropriated and used for irrigation. An 
irrigation project now being constructed under the Carey Act will store the flood 
water of Teton River in the reservoir about 5 miles north of the gaging section. 
The capacity of the reservoir is 90,000 acre-feet, and it can be increased to 210,000 
acre-feet by raising the top of the dam 20 feet. The reservoir will serve 120,000 
acres of land on the north side of the river. The water will be diverted hall a 
mile above the gage. 

Aocoracy. — ^Accurate determination of dischaige during high stages is difficult because 
of the shifting channel. 



iStatioa waa deacrfbed in earlier reporta aa "Teton Riyer near BeUeview, Mont." 
moved from BeUeview to Strabane in 1910.

BUEFAOB WATEB SUPPLY, 1911, PABT VI. 



KVB8XLBKBLL BIVX& AT HABLOWTOV, KOVT. 

Location.— In sec. 26, T. 8 N., R. 15 E., at the highway bridge 1 mile south of Har- 
lowton. Takes place of station formerly maintained at Shawmut. 

BecordB available.— July 11, 1907, to December 31, 1911. 

Drainage area. — Not measured. 

Oages.— The original gage was destroyed in October, 1908; on April 10, 1909, a tempo- 
rary staff gage was installed which read 0.73 foot too l^gh. On May 24, 1909, a 
standard chain gage was placed on the upstream side of the new public highway 
bridge at a datum 0.52 foot higher than the bench mark and the datum of the 
bench mark was raised 0.52 foot. All gage heights for 1909 were corrected to the 
new datum. 

ChanneL — ^Bed of stream composed of sand and gravel; will probably shift in flood. 

Discharge zneasurements. — Made from bridge or by wading. 

Diversions. — ^A large part of the valley is irrigated and many small ditches take water 
from the Musselshell; practically the entire flow of the stream is appropriated. A 
minimum discharge of 2 second-feet is recorded during the irrigation season at 
thb station. 

Discharge jMosfuremenU of Musselshell River at HarlowUm, Mont.y in 1911.

IiOcatioxi.^At the Shaw & Elliott ranch, 5 miles southeast of Hailowton, Mont., a 
few miles above the junction of the American Fork with the Musselshell. 

Becords available.— July 28, 1907, to December 31, 1911. 

Qa^e. — Chain fastened to upper rail of small wagon bridge; datum unchanged. 

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

Discharge zneasurementa. — ^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.

SURFACE WATER SUPPLY, 1911, PART VI. 



GhaaneL— Pennanent. 

Discharge measurements. — Made from a cable installed at the time of the installa- 
tion of the new gage. 

Winter flow.— Affected by ice. 

Flood discharge.— The river oveiflows its banks at gage height of 12 feet; hig^water 
marks show that the flood of June, 1908, reached a stage of 15.4 feet on the gage. 
The flood width was 850 feet and the cross section about 2,600 square feet. 

BivendoDS. — A number of small ditches divert water to irrigate meadow lands in the 
river bottom; a considerable amount of this water returns to the stream as seepage 
and waste. No storage is used above the station. 

Accuracy. — Records excellent except during the winter months.

SURFACE WATER SUPPLY, 1911, PART VI. 



MILK RZVS& AT HAVBJE, MOHT. 

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

BecordB available.— May 15, 1898, to December 31, 1911. 

Drainage area. — ^About 7,300 square miles. 

Gage. — Chain &stened to bridge rail on the downstream side; datum unchanged. 

Channel. — Shifts . 

Discharge measurements. — ^Made from bridge or by wading. 

Winter flow. — From the last part of November to the first part of April the river at 
Havre is frozen entirely over and in portions of the cross sections it is usuaUy 
frozen to the bottom. 

DiversionB. — ^An irrigation company in southern Alberta, Can., haa been granted an 
appropriation of 500 second-feet of the low-water flow and 1,500 second-feet of the 
high-water flow, and a canal of 330 second-feet capacity has been partially con- 
structed but no water has been diverted. There are no other important irriga- 
tion rights above Havre, but farther downstream are five laige canal systems sup- 
plied directly from Milk River and irrigating about 22,000 acres. Preliminary 
steps tow£rd 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. Al- 
though 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.

VO&TH FO&K OF MZLK BIVX& HXAB CHXHOOS. KOITT. 

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 of the North Fork with the main stream. 

Eecords available.— April 22, 1905, to December 31, 1911. 

Drainage area. — Not measured. 

(lage. — Chain on the left bank near the house of the observer. 

ChaoneL — Sandy and shifting. 

Dischargre meaaurementB. — ^Made by wading or at the cable near the gage. 

^Hnter flow. — Ice present; gage readings impracticable. • 

IHverBiona. — ^Three canals, which divert in the aggregate about 20 second-feet, take 
out above the station; several small pumping plants, which supply water for irri- 
gating the bottom land along the river valley, also operate above the station. 
Below the station the Matheson and Cook canals divert water for irrigating land in 
Milk River Valley near the mouth of the North Fork. The aggregate appropria- 
tion for these canals is 78 second-feet. 

Accuracy. — ^Results may be considered reliable as a fttir rating curve has been con- 
structed. 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.

SUKFAOB WATBB SUPPLY, 1911, PABT VI. 



Drainage area.^Not measured. 

Oage.—^taff . The gage was first established at bridge No. 455 of the Great Northern 
Railway, half a mile west of Ashfield ; it was moved to its present location, 2} miles 
forther upstream, December 31, 1903. 

OhanneL— The stream carries little water except at the times of the spring floods or 
heavy rains; during the summer months the channel is obstructed by a dense 
growth of weeds and willows, which have to be cleared out occasionally. At 
medium and high stages a second channel, known as Beaver Creek Overflow, 
receives the stream above the station, fills a depression to the west of the main 
channel, and reenters at a point some distance below the gage. 

DiBeharge measurementB. — ^Made from a cable or by wading. 

^Hnter flow.— Ice present during the winter months. 

Divendons.— Water is diverted from Beaver Creek by small ditches leading from the 
stream and by small pumping plants near the banks. 

▲ccuracy. — ^Results are only fair, as the growth of weeds and willows in the channel 
makes the construction of a permanent rating curve difficult. DaUy discharge 
given for days with gage heights only; no monthly estimates have been made.

gage; low-water measurements are made by wading near the gage. 
Aocnracy. — ^Records poor. Lack of measurements in 1911 has prevented the making 

of estimates of daily and monthly discharge.

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 Coimty, these canals are located in 
Chouteau County and are used to irrigate lands in the vicinity of 
Harlem and Chinook. 

The canals are all built on small grades and in soil which is easily 
eroded. In many of them silt has been deposited, and nearly all of 
them contain a growth of weeds and moss. At low stages, the water 
is uniformly sluggish. In order to divert water into the laterals 
checks are erected in the main canals, and these checks often produce 
back-water effects for long distances above. They were put up imder 
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.

a Estimated. 
Note.— Means for periods Dec IB to 31, 1910, and March 1 to 7, 1911, estimated at 950 second-feet. 
TSLLOWSTOVB KTTEB AT XUHTLST, XOVT. 

Locatioii.—In the SW. i sec. 24, T. 2 N., R. 27 E., at the new steel highway bri^ 1 
mile below Huntley, Mont., 1 mile below Pryor Creek. Station replaces that 
formerly maintained at Junction. 

Becorda available.— October 1, 1907, to December 31, 1911. 

Drainage area. — 12,000 square miles. 

Oage.— Chain fastened to bridge rail; datum unchanged. 

Channel.— Shifts. 

Discharge meaaurements. — Made from downstream side of bridge. 

Winter flow. — River frozen entirely over in places during the winter, but during 
the coldest seasons open channels with floating ice are not of unconunon occur- 
rence. 

DiyendonB.— 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 di£ScuIty 
of diversion. 

Accuracy.— Conditions for obtaining accurate data at this station are only fair and 
many dischaige measurements are necessary to define a good rating curve.

TEIXOWSTOVE &IVXB AT LOWXR TSIXOWSTOVB DAM, AT XHTAKB, MOVT. 

Location. — At the Lower YellowBtone diversion dam, at Intake and 18 miles 
below Glendive, Mont. 

Becorda available. — ^Records by War Department and Department of Agriculture, 
1893 to 1903; August 1, 1903, to December 31, 1911, by United States Geological 
Survey. Records January 1 to December 31, 1911, from observations at the pres- 
ent station, which replaces the one formerly maintained at Glendive. 

Gage. — ^A chain gage on the north abutment of the dam. The gage readings show the 
depth of water on the crest of the dam. 

Winter flow.— Affected by ice. 

The dam. — ^The dam, a rock-filled timber-crib structure on a pUe foundation, was 
completed January 29, 1910. It is 700 feet long, crosses the stream at right angles 
to the current, and will raise the low-water level of the river about 4 feet. The 
dam is specially designed to resist the destructive effects of ice by having an 
approach on a slope of 3 to 1, and the downstream foce is ogee-shaped and pro- 
tected by a heavy rock apron. 

Diversiona. — ^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 dischaige 
measurements made at Glendive, a dischaige curve was constructed which is 
applicable to the gage heights of Lower Yellowstone dam, and should give fair 
results.

ranch buildings. When the station was established a secondary staff gage to be 
used during extreme high water was installed about 300 feet below the regular 
gage and at a different datum. The regular gage was undermined during the 
high water of June and July, 1908, and readings were discontinued August 19 of 
that year. The present gage, which is the old secondary gage, has been read since 
October 1, 1908. The gage heights on the new gage are not comparable with those 
read on the old gage. 

Channel. — Composed of rough gravel. 

Ducharge measorenientB. — ^Made by wading near gage at ordinary stages; at high 
stages made from footbridge. 

^^nter flow. — Stream freezes over during winter months. 

Diversions. — ^Two small ditches divert water above the station.

WUD RIVEK AT RIVEBTON, WTO. 

Location. — At highway bridge in sec. 2, T. 1 S., R. 4 E., three-fourths of a mile east 
of Riverton and three-fourths of a mile above its junction with Little Wind River. 

Becords available. — May 15 to November 11, 1911. From May 14, 1906, to Novem- 
ber 1, 1908, a station was maintained at Walker's ferry, about 1 mile above the 
present station. As no streams enter between, the records at the two points are 
comparable. 

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

Oage. — Chain gage. 

ChanneL— Shifting after high water. 

Discharge measurementB. — ^Made from bridge. 

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

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

Accuracy. — Conditions are fovorable for accurate results and the estimates should be 
reliable. 

Ck>operation. — Station maintained in cooperation with the State engineer.

SUBFACE WATER SUPPLY, 1911, PART VI. 



G&ge. — Chain gage. The original gage was located at the highway bridge. On June 

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

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

it was installed. 
Channel. — Practically permanent. 
Discharge measurements. — ^Made from the highway bridge during high water and 

by wading during low stages. 
Winter flow. — Ice causes backwater during the winter months and the records are 

discontinued. 
Diversions. — Prior to July 1, 1912, adjudicated diversions from Little Pope Agie 

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

second-feet. 
Accuracy. — As the station has not been completely rated no estimates of discharge 

have been made. 
Cooperation. — Station maintained in cooperation with the State engineer.

BHOSKOne BIVXB AT COBBXTT DAM, WYO. 

Location.->In the N£. \ sec. 7, T. 53 N., B. 100 W., at the Corbett diversion dam, 8 
miles below Cody, Wyo. 

Becorda available.— April 20, 1908, to October 25, 1911. 

Bxaina^fe area. — ^Not measured at this station; the drainage area above Cody is 
1,400 square miles. Sage Creek, the only important tributary that enters be- 
tween this station and Cody, drains only about 25 square miles. 

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

Detezminationa of dlacharge.— The discharge is computed by considering the 
dam as a weir and the sluice tunnel gates as submerged orifices. The dam is of 
reinforced concrete, of the buttressed type, having on the upstream side a deck 
2^ feet thick sloping 1 to 1 and supported by buttresses 2 feet thick spaced 14 
feet on centers; it raises the low-water elevation of the river 10.2 feet; the length 
between abutments is 400 feet. 

Cooperatdon. — Gage heights and gate openings furnished by the United States 
Redamation Service. 

The following dischaige measurement was made by B. E. Jones at the highway 
bridge at Cody: 
August 7, 1911: Gage height, 1.83 feet; discharge, 3,720 second-feet.

Draina^ area. — Not measured. 

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

ChaxmeL — ^Practically permanent; bed of 'stream is composed of gravel and cobble- 
stones. 

Discharge xneaanrexnents. — ^Made from the footbridge at high stages and by wad- 
ing at low stages. 

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

irrigation above the gage. About 7,500 acre-feet of water are stored in the moun- 
tains on the headwaters of the stream and diverted in the Little Goose Creek 
drainage area. There are also a number of smaller diversions into the Little 
Goose Creek drainage area after the stream leaves the mountains. The records 
at the station show the amount of water that is not used in the Big Goose drainage 
basin.

VO&TK FOKK 07 POWDUt BZVBm STSAB SATOU, WTO. 

Locataon. — ^At Jacob Afblter's ranch, on the county rood 4 miles north of Kaycee, Wyo. 

Records available.— May 11 to Dumber 31, 1911. 

Diajna^ area. — Not measured. 

Gkkge. — ^An overhanging diain gage on the left bank one-fourth mile above the high- 
way bridge. From May 11 to July 28, 1911, the gage was located 200 feet farther 
upstream and at a different datum. It was moved because it was within the 
influence of backwater from beaver dams. 

ChaxmeL — Practically permanent. The bed of the stream at the point of control 
below the gage is composed of permanent gravel and cobblestones, but at the gage 
it is composed of sand and gravel and is liable to shift during high stages. 

Discharge meaaurementa.— Made from the highway bridge one-fourth mile below 
the gage at high stages and by wading near the gage at low and medium stages. 

Winter flow. — Gage heights are affected by ice during the winter months. The 
channel water is frozen solid at times. 

Diverdona. — During the irrigation season the greater part of the flow of the stream is 
diverted above the station. 

Accnraoy.— Fair. Gage heights before July 28 were affected by backwater from a 
beaver dam below the gage. After July 28 the records are considered good.

CLEAB CSEEK NZAB BUFFALO. WTO. 

liOcation. — In the Bighorn National Forest, at Camp Comfort, in the SW. \ eec. 8, 
T. 50 N., R. 83 W., II miles west of Buffalo; three-fourths of a mile below the 
junction of the North and South forks. 

Beoords available.— October 22, to December 31, 1911. From May 1, 1896, to 
March 11, 1900, a station was maintained by the State engineer at a point 4 miles 
west of Buffalo, where a measuring flume was built. From October 24, 1902, to 
December 31, 1904, a station was maintained at Buffalo. The records at the two 
points are not directly comparable, as a number of irrigation ditches divert water 
between and a few intermittent tributaries enter. 

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

Qa^. — Vertical staff. 

Channel. — Data too meager to determine. 

DiBcharg^e meanirementa. — ^Made from bridge during high water and by wading 
at ordinary stages. 

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

Diveiaiona. — ^There are no diversions above the station and the records at this point 
represent the natural run-off. Below the station, however, there were adjudi- 
cated diversions amounting to 333 second-feet prior to July 1, 1912. 

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

Cooperation. — Station maintained in cooperation with the United States Forest 
Service. 
The following discharge measurement was made by H. B. Waha. 
October 22, 1911: Gage height, .90 feet; discharge, 26 second-feet.

HEAKT BIVEB HBAB BICKABBTOB. B. DAB. 

Location.— In or near sec. 21, T. 138 N., R. 92 W., about 11 xmlee south of Richardton, 
opposite the observer's house, which is 1 mile below the highway bridge at which 
the station was formerly maintained. 

BecordB available.— May 18, 1903* to September 30, 1911. 

Drainage area. — 1,250 square miles. 

Gage. — Readings in 1911, up to September 4, were obtained from a staff gage set in 
the margin of the chamiel at the ford about 30 rods above observer's house and 
about 1 mile below the highway bridge. This staff gage and the chain gage at the 
highway bridge were found to give identical readings untU about May 15, when 
slides into the river below the highway bridge caused the gage heights at highway 
bridge to be worthless. On September 4, 1911, an overhanging chain gage was 
installed opposite the observer's house, its zero being set so that a reading of 3.3 
on the rod gage 30 rods above is 23.3 on the chain gage. On account of a beaver 
dam below the gage, readings during October are uncertain. 

ChanneL — Not permanent. 

Discharge measurementB. — ^At high stages, made from bridge; at ordinary and low 
stages, by wading. 

Winter flow. — ^Affected by ice. 

Accuracy. — Sufficient high and medium stage measurements have not yet been 
made to define the upper part of the rating curve.

a New gage Sept. 3, 1911. 

CANNONBALL BIVEB BASIN. 
CAmOirBALL RIVER ITEAR STEVEXTSOIT, IT. DAK. 

liocatdon. — On the west side of the river near the south side of sec. 23, T. 133 N., R. 
82 W., at M. H. Burdick's house, immediately above the ford, about 1 mile south- 
east 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 aTailable.-June 10, 1903, to November 30, 1908; August 9 to December 31, 
1911. 

Drainage area.— 3,670 square miles. 

Oages. — Standard chain on projecting cantilever timber; a temporary rod gage on the 
left bank was used until the chain gage was ready. 

ChanneL — Bed of stream composed of gravel and stones, in places covered with eilt 
to the depth of 1 foot. At the rapids 600 feet below the gage the bed is of clean 
gravel and stones. During floods the silt may be washed away and later rede- 
posited at some points. 

IMscharge measurexnents. — ^At low and medium stages made by wading at the 
ford 15 rods below the gage or at the riffle 55 rods below; at medium and high stages 
measurements may be made by use of the car and cable at the old Stevenson 
station, about 1 mile farther downstream. The discharge is practically the same 
at the two points, except that a small draw, which enters midway between the 
gage and the cable on the north side, carries a small flow for a few hours after a 
rain. 

Winter flow.— Affected by ice.

Accuracy.— The gage heights obtained at this station are not of sufficient value to 
publish as the observer did not read the gage so long as there was no visible change 
in the flow, but recorded the same gage height day after day. However, he states 
that he kept close watch of the stream and that there was no perceptible change 
during the spring until the last of June, when it dropped suddenly about 0.2 in 
gage height, as he had recorded. The flow during the rest of the season after 
August 13, when a hydrographer visited the station, probably varied only slightly.

WHITE RIVEE BASIN. 



WHITB BZVB& inBAB ZHTBBIOB,, S. DAK. 



Location. — ^At the steel highway bridge near the southwest comer of sec. 7, T. 4 S.» 
R. 18 E., where the county line between Stanley and Pennington counties inter- 
sects White River, 3 miles southwest of Interior, S. Dak., a station on the Chicago, 
Milwaukee & St. Paul Railway. 

Records available.— June 24, 1904, to November 30, 1906, at old station in T. 3 S., 
R. 18 E.; August 24 to November 30, 1911. 

Drainage area. — 4,090 square miles. The area above the present site is about 15 
square miles less than the area above the station maintained during 1904-1906 
near Westover. 

Gage. — A vertical rod attached to the lower side of the first pier (nearest the shore) at 
the left end of the bridge, installed August 31, 1911, and supposed to read the same 
as the temporary rod gage which was placed August 24 on a tree on the left bank 
at the turn of tiie river near the southwest comer of NW. i sec. 17. 

GhanneL — ^Probably changes gradually; bed composed of sand and some quicksand; 
left bank steep and clean; ri^t bank gently sloping and clean; current, medium. 
At low stages all the water may pass under one span (67-foot); at the highest stage 
the water passes under two 67-foot spans and 120 feet of trestle approach, but prob- 
ably two-thirds of the flow passes under the two spans. 

Discharge meaaurenientB. — ^Made from the highway bridge.

NIOBBABA BIYER BASIN. 
HIOB&ABA BIVXB AT HIOBBABA, NZBR. 

Location. — ^At the Grovemment highway bridge spanning the main channel in the 
SE. i sec. 18, T. 32 N., R. 56 W., half a mile from the depot at Niobrara. The 
station is 1} miles above the mouth. No tributaries enter below. 

Records available.— August 19, 1910, to October 5, 1911. From May 11 to October 
25, 1902, a station was maintained at a highway bridge 1 mile southwest of Niobrara. 

Drainage area. — Not measured. 

Gtege.— Vertical staff. 

ChanneL— Shifting and within the influence of backwater from Missouri River. 

Discharge meaaurementB. — ^Made from bridge. 

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

Diversions. — ^Prior to September 1, 1912, there were approved diversions of 561 
second-feet for irrigation and 2,755 second-feet for power from Niobrara River 
above the station. There were also approved diversions of 180 second-feet for 
irrigation and 453 second-feet for power from tributaries entering above. In 
Wyoming there are adjudicated diversions of 24 second-feet from the Niobrara and 
tributaries. 

Accuracy. — Owing to the shifting channel and insufficient discharge measurements, 
no estimates of discharge have been made. 

Oooperation. — Station maintained in cooperation with the State engineer, by whom 
the field data are furnished.

BIG SIOUX BIVEB BASIN. 
BOOK BIVBB AT LXTTXXn, Mm. 

Locatioxi. — ^At the Bock Island Railroad bridge at Luveme, Minn., 3} miles above 
the mouth of Elk Greek. 

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

Draina^ area. — 440 square miles. 

Oa^. — ^Votical staff. 

ChanneL — Plobably permanent; small rapids just below gage; severe floods will cause 
a change. 

DiMhar^ xneaaureznents. — ^Made from the railroad bridge at flood stage, from the 
highway bridge at medium stage, and at a wading section in low water. 

Winter flow.— From December to March the river is frozen over at the station and 
measurements are made through the ice to determine the winter discharge. 

Artificial controL — ^The flow of the river is not artificially controlled above Luveme, 
ae there are no dams except a low rock dam a short distance above the station, 
which does not regulate the flow but simply raises the water level about 2 feet. 

Cooperation. — Station maintained in cooperation with the State Drainage Com- 
mission.

Note.— Relation of gage height to discharge affected by ice about Nov. 24 to Dec. 31. Daily di9cliar|t 
computed from a rating curve well defined between 16 and 346 seoond-feet (gage heights 1.6 and 4 feet). 
Discnarge Nov. 25 to Dec. 31 estimated, because of ice, lh>m observer's notes, dimatdogic records, and one 
disdiarge measurement; mean discharge Nov. 24 to 30 estimated 26 second-net, varying from about 30 to 
24 seoond-feet; mean disdiarge Dec 1 to 31 estimated 23 second-feet, varying from about 37 to 10 second-

PLATTE BIVEE BASIN. 
HO&TH PLATTE RIVmB AT SA&ATOOA, WTO. 

Location. — ^At hi^way bridge in Saratpga, 2 miles below the mouth of Spring Greek. 

BeeordB available.-June 9, 1903, to October 31, 1906; April 1 to December 17, 1909; 
April 27 to November 10, 1911. 

Drainage area. — 2,920 square miles. Measured from Land Office maps. 

Gage. — A chain gage was installed at the bridge in 1911. The original gage was a 
vertical staff located 100 yards beloy the bridge. The relation between the two 
gages has not been determined. 

Channel. — Practically permanent, except that tie drives may cause backwater for a 
few days. 

Discharge measurementB. — ^Made from bridge. 

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

Divezsiona. — Prior to July 1, 1912, there were adjudicated diversions of 86 second- 
feet, from the North Platte above Saratoga, in Wyoming, and 934 second-feet from 
tributaries entering above. In the Colorado portion of the drainage area there are 
adjudicated decrees for diversions of 3,060 second-feet from the headwaters of the 
North Platte. 

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

Cooperatioii. — Station maintained in cooperation with the State engineer.

VO&TK PULTTS BIVX& AT PATKYIVDZB, WTO. 

Location. — ^Half a mile Bouth of Pathfinder, 800 feet below the mouth of the canyon, 
in sec. 24, T. 29 N ., R. 84 W. The nearest tributary is Canyon Creek, which enters 
2 miles above. 

Beoords available.— May 9, 1905, to December 3, 1911. 

Brainag'e area. — ^About 12,000 square miles. 

Oage. — Chain gage; datum unchanged. 

ChanneL — Condition not known, as only final results are furnished. 

Discharge meaenrements. — ^Made from car and cable. 

WinteT flow. — Ice causes slight backwater for short periods. 

Controlled flow. — ^The Pathfinder dam, one-fourth mile above the station, forms a 
reservoir of 1,025,000 acre-fpet capacity. This reservoir materially changes the 
natural nm-off of the river, as is seen by a comparison with the records of inflow. 

DivezBioxxa. — ^Prior to July 1, 1912, there were adjudicated diversions of 58 second- 
feet from the North Platte between Samtoga and Pathfinder, and 1,550 second-feet 
from intervening tributaries. Near Whalen, 150 miles below, the water from the 
Pathfinder reservoir is diverted by the interstate canal and used to irrigate land 
in Nebraska and Wyoming. Further canals are contemplated by the Reclama- 
tion Service. 

Cooperatiozi. — Station maintained in cooperation with United States Reclamation 
Service, by which the records are furnished. 

The following discharge measurement was made by H. D. Comstock: 
May 25, 1911: Gage height, 3.40 feet; discharge, 1,640 second-feet.

VORTH PLATTX RXVZR AlTD ZHTXR8TATE CAJTAI. AT WHALEH, WYO. 

Location.— At the head of the Interstate canal at Whalen, in sec. 11, T. 26 N., R. 65 
W. The nearest important tributary is Cottonwood Canyon Creek, an intennittent 
stream which enters 1} miles below. 

Becords available.— May 1, 1909, to December 31, 1911. These records represent the 
dischaige passing the over&ll weir at Whalen and also the amoimt of water passing 
the head gates of the canal, which are located just above the Whalen weir. From 
June 14, 1900, to November 17, 1908, a station was maintained at Guernsey. The 
flow between the two points is very nearly comparable, as only a few intermittent 
tributaries enter between the two points. 

Drainage area. — Not measured. 

Oage. — ^To determine the flow over the weir a vertical staff is used, its zero being at 
the weir crest. The discharge is then computed by a weir formula. There are 
also four sluice gates in the dam, through which the discharge is computed . There 
is also a second gage in the river 75 feet downstream from the crest gage, having 
its zero 10.00 feet below that of the weir gage. This latter gage is only used in 
computing the dischaige through the gates when the openings are submerged. 
The discharge through the head gates of the canal is computed from the nine gate 
openings. There is a vertical staff located in the canal 1,000 feet below the head 
gates, which is used in computing the discharge when the head-gate openings are 
submerged. 

Discharge measurementB.— In order to check the coefficients used in the discharge 
computations, a car and cable have been erected 1 mile downstream. Sufficient 
measurements have not yet been made to complete the checking. 

Artificial control.— The discharge represents largely the effect of the Pathfinder 
reservoir which stores water for use in the Interstate canal. 

DiTersions.— Prior to July 1, 1912, there were adjudicated diversions from North 
Platte River of 319 second-feet between Pathfinder reservoir and the Wyoming- 
Nebraska line, exclusive of the diversion by the United States Reclamation 
Service. It is not known what percentage of these diversions is above the stations. 

Cooperation. — Station maintained by the United States Reclamation Service, by 
which the records are furnished.

Note. — Monthly discharge oompated by engineers of the United States Geological Survey from data 
famished by the IJnited States Redamatlon Service and published herewith. 

VO&TK PLATTB BIVUl VZAB MXTCKBLL, NZBK. 

Location. — ^At highway bridge 1 mile south of Mitchell, on line between sees. 27 and 

28, T. 23 N ., R. 56 W. The nearest tributary is Spottedtail Creek, an intermittent 

stream entering just below the station . The only important tributary between the 

station and the Wyoming line is Horse Creek. 
KecorcUi aTaUable.-^June 3, 1901, to December 23, 1911. From May 29, 1897, to 

October 31, 1900, a station was maintained near Gehring. Although no tributaries 

enter between the two points, the records are not directly comparable during the 

irrigation season, as water is diverted for irrigation. 
Draina^ area. — 24,400 square miles. 

Oage. — Chain gage; datum lowered 1 .00 foot on May 3, 1902, to avoid negative readings. 
Channel. — ^Very slightly shifting. 
Diflchari^ meaaurementB.— Made from bridge. 
Winter flow. — ^The river is frozen over during the winter months and records are 

discontinued. 
Artiflclal control. — ^The Pathfinder reservoir of the United States Reclamation 

Service controls the flow at this station to a certain extent. 
Diversioiia.— Prior to September 1, 1912, there were approved diversions of 2,188 

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

Mitchell, and 75 second-feet from intervening tributaries. 
Accuracy. — Conditions are fovorable for accurate results and the estimates should be 

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

the field data are furnished.

VOBTH PLATTX RIVER AT VORTH PLATTX, HBBR. 

Location. — ^At highway bridge half a mile north of North Platte, in sec. 28, T. 14 N., 

R. 30 W., 1 mile below mouth of Scout Creek and 4J miles above the junction with 

the South Platte. 
Records available.— February 25, 1895, to December 23, 1911. 
Drainage area. — ^28,500 square miles. 
aage.— A staff gage installed October 15, 1910. From October 5, 1894, to May 31, 

1910, the gage was a vertical staff at the railroad bridge 2 miles east of North Platte. 

On March 25, 1910, the station was moved 2 miles upstream to its present site and 

a chain gage reading to a different datum was installed. This gage was stolen 

July 1, 1910, and the records interrupted until October 15, 1910, when the present 

gage reading to a different datum was placed in position. 
Channel. — Very shifting. 

Diacharge xneaaurementa. — ^Made from highway bridge. 
Winter flow. — ^The river frequently freezes to the bottom during the winter, as it is 

very shallow. 
Diversiona. — Prior to September 1, 1912, there were approved diversions of 3,626 

second-feet from the North Platte between Mitchell and North Platte, and 927 

second-feet from intervening tributaries. 
Accuracy. — Owing to the very shifting channel the estimates have been obtained by 

the indirect method and can be considered only fair. 
Cooperation. — Station maintained in cooperation with the State engineer, by whom 

the field data were furnished.

Discharge estimated at 2,500 second-feet Dec. 24 to 31. 

PLATTE BIVX& VSAB COLXTMBITS, BBBB. 

Location. — ^At Meridian bridge 3 miles south of ColumbuB on line between sec. 36, 
T. 17 N., R. 1 W., and sec. 31, T. 17 N., R. 1 £., about 10 miles below the mouth 
of Prairie Creek and 5 miles above the mouth of Loup River. 

BeeoidB available.— June 4, 1895, to December 31, 1911. 

Draina^ area. — 56,900 square miles. 

Gage. — ^A chain gage installed July 25, 1910. The bridge and the original gage pre- 
viously 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. 

Chaxmel. — Extremely shifting; at this point the river flows in the channels known as 
the main, middle, and south channels. The gage is located in the main channel. 

I>i8ehaxge xneaanrementa. — ^Made from bridges spanning each channel. 

Winter flow. — ^The river freezes over during the winter and records are discontinued. 

Direnioiia. — Prior to September 1, 1912, there were approved diversions of 4,888 
second-feet for irrigation and 1,500 second-feet for power from Platte River 
between the junction of the two branches and Columbus, and this diversion, 
together with the evaporation from the wide shallow channels, frequently causes 
the flow to cease at this point during the late summer and fall. 

Aecozaey. — ^The extremely shifting channel makes it impossible to make estimates 
of daily discharge without almost weekly discharge measurements, as the gage 
heights are little if any index of the flow. 

Cooperation. — Station maintained in cooperation with the State engineer, by whom 
the field data were furnished.

ChamiaL — ^A abort dutance below the etatioii is a low divenion dam which may cause 
backwater whenever additional brush or drift collects on its crest. 

I>iBchaxgB measurementB.— Made from car and cable. 

Winter flow. — ^Ice causes backwater during the winter months, and the records are 
discontinued. 

BxrezBloiiis. — ^Three large irrigation ditches divert water at a point 1 mile above the 
station. The smelter company has a pipe line which diverts water above the sta- 
tion, but as the tailrace of the power plant which the pipe line supplies is located 
just above the station, the amount diverted passes the gage. Water is also diverted 
below the station. Prior to July 1, 1912, there were adjudicated diversions from 
Encampment River amounting to 61 second-feet and from tributaries entering 
above 31 second-feet. 

Aoearacy. — ^The lodging of debris on the point of control makes the conditions some- 
what uncertain, and therefore the estimates of flow can not be considered better 
than fair or possibly good. 

Cooperation. — Station maintained in cooperation with the State engineer.

AOCK CREEK NEA& ABLnrOTOH, WTO. 

Location.— At highway bridge in eec. 25, T. 19 N., R. 79 W., 1} miles upstream from 
Arlington post office; 1 mile below the mouth of Overiand Greek, the nearest 
tributary. 

Becords available. — ^April 22 to November 4, 1911. 

Draina^ area. — 70 square miles (measured from Forest Service Atlas). 

Gage. — ^Vertical staff. 

Channel. — Shifting. 

Discharge measurements. — ^Made from bridge. 

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

Diversions. — One small ditch diverts water above the station for irrigation. 

Accuracy. — As the channel shifts the estimates have been obtained by the indirect 
method and can be considered only fair except for those months when the meas- 
urements indicated no shift, when they are probably good. 

Cooperation. — Station maintained in cooperation with the State engineer and the 
Rock Creek Conservation Co.

SXTBFAOE WATBB SUPPLY, 1911, PABT VI. 



ULRAMJE BIVBR AT WOODS LAITDZirO, WTO. 

Location. — ^At highway bridge at Woods Landingi in sec. 11, T. 13 N., R. 77 W., a 
short distance below the mouth of Wood Creek, the nearest tributary. 

Records available.— May 7 to November 11, 1911. During 1889, 1890, and 1891 a 
station was maintained at Woods Landing by the State engineer, and the results 
were published in his reports. From April 12, 1896, to September 30, 1900, a 
station was maintained at a point 400 feet above the present site, and as no streanis 
intervene nor ditches divert water the records at the two points are comparable. 

Draina^s^ area. — Not measured. 

Gage. — ^Vertical staff; no determined relation between present gage and gagee used 
prior to 1900. 

Channel. — A short distance below the bridge there is a diversion dam which is the 
control point for the station. As this dam is not permanent conditions are some- 
what changeable. 

Discharge nxeasurenxents. — ^Made from bridge during high stages and by wading 
at ordinary stages . 

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

Diversions. — ^Practically no water is diverted between the stations near John and 
Woods Landing. 

Cooperation. — During 1911 station was maintained in cooperation with the State 
engineer.

SURFACE WATER SUPPLY, 19U, PART VI. 



SOUTH FORK OF SOtTTR PLATTX &ZVBK AT ULKM OXOROX. COLO. 

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

Lake Geoige, in the Pike National Foreet, about 2 miles above the mouth of Cay- 

lor Gulch; no tributary between the outlet of the lake and the station. 
Records available.— October 22, 1910, to December 31, 1911. 
Draina^ area. — Not measured. 
Oage. — ^Automatic recording gage installed in 1911, reading to the same datum as 

the original staff gage. 
Ghaxmel. — Conditions in the channel will remain unchanged as long as the control 

for the station— a 2-foot timber-crib dam 50 feet below the gage — remains perma- 
nent. 
Disohax;^ measurements. — UsAe 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. 
Artiflcial control. — ^The discharge at the station is controlled naturally to some 

extent by the regulating effect of Lake George, which has an area of one-half 

square mile. 
Diversions. — ^There are court decrees for diversions of 1,076 second-feet from the South 

Fork above this station and for diversions of 1,816 second-feet from tributaries 

entering above. 
Accuracy. — ^As the station has not been completely rated, no estimates of discharge 

have been made. 
Cooperation. — Station maintained in cooperation with United States Forest Service 

and the State engineer of Colorado.

the State engineer, and the records from 1895 to 1898 were taken under the direc- 
tion of the Denver Power & Irrigation Co. 

Drainage area. — 2,610 square miles. 

Gage.— An automatic recording gage, installed by the State engineer March 14, 1910. 
From March 28, 1902, to May 7, 1905, the gage was at the highway bridge. On the 
latter date it was moved to its present site, 150 feet below. It is probable that the 
new gage read to a somewhat different datum. The recording gage is referred to 
the datum of the gage established in 1905.' 

Ohaimel.-— Shifting. 

Discharge measurements. — ^Made from car and cable during high water, and by 
wading at low stages. 

^C^ter flow. — ^Ice causes backwater during a portion of the winter months and 
measurements are made to determine the flow. 

Artifldal control.— The flow is controlled to a certain extent by the Cheesman 
reservoir which is on the South Fork about 20 miles above the forks.

SOUTK FLATTE RZVXR AT DSWBR. COLO. 

Location. — ^At the Sixteenth Street viaduct in Denver; 500 feet below mouth of 
Cherry Creek. 

Records available.— May 7, 1895, to December 31, 1911. 

Drainage area. — 3,840 square miles. 

Gkkge. — ^Automatic recording gage installed August 12, 1909. The original gage was 
located at the Twenty-third Street viaduct. In July, 1895, a new gage was 
installed at the Fifteenth Street bridge. In August, 1898, an inclined staff gage 
was placed on the opposite side of the river, but referred to the same datum. 
This gage was destroyed by high water in June, 1900, and for the remainder of the 
year the gage installed in July, 1895, was used. This gage was stolen, and a new 
one was placed between the Fifteenth Avenue and Sixteenth Avenue bridges 
May 15, 1901, reading to the same datum. This gage also was stolen and was 
replaced on June 10, 1903, by a vertical staff near the same place and having the 
same datum. The automatic gage is referred to practically the same datum as 
the preceding verticalstaff. 

Channel.— Shifting. 

DiBcharge measurements.— Made from the Fifteenth Street bridge during high 
water and by wading at low-water stages. 

Winter flow.— The flow at this point is seldom affected by ice. 

Diversions. — Between this station and the one at South Platte there are court decrees 
for diversion from South Platte River of 2,226 second-feet and from intervening 
tributaries of 1,466 second-feet. 

Cooperation. — Since 1907 station has been maintained by the State engineer, by 
whom the records are furnished.

SOUTK PLATTE &ZVXR HSAB KKBSEY, COLO. 

Locatloii.— At highway bridge in sec. 9, T. 5 N., R. 64 W., If miles north of Kersey, 
2 miles below the entrance of Lone Tree Creek, an intermittent stream, and 3 
miles below the mouth of Cache la Poudre River. 

Becorda available.— April 27, 1901, to October 31, 1903; March 1, 1905, to December 
31, 1911. 

Draina^ area. — ^9,500 square miles. 

Oag^.—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 difierent from that 
of the original gage, but have remained permanent since. The original gage, a 
vertical staff, was used imtil Jime 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. 

Chaimel.— Shifting. 

Discharge meaaurements.— Made from the bridge during high water and by wad- 
ing at ordinary stages. 

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

Divendona.— 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 interven- 
ing tributaries, besides numerous flood-water decrees. 

Accuracy.— Although the channel is shifting, sufficient diachaige measurements have 
been obtained to enable estimates of flow to be made which may be regarded as 
reliable. 

Oooperation. — Station maintained in cooperation with the State engineer. 

Discharge measwremenU of South Platte River near Kersey, Colo., in 1911.

SURFACE WATEB SUPPLY, 19U, PABT VI. 



Oage.—When the station was reestabliflhed in 1908 a gage was placed in each of the 
two main channels; both gages read practically the same as the original gage on 
the lower bridge 2,000 feet below the present site. The datum of the gages has 
remained unchanged. 

ChaimeL— Shifting. 

Diflchar^ measurementa. — ^Made from the pile bridge during high water, and hy 
wading at low-water stages. 

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

Divendons.— Between Kersey and Julesbuig 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 Greek in Wyoming and Nebraska 
and Grow Greek in Wyoming, besides numerous flood decrees. Between the State 
line and the mouth diversions of 206 second-feet from the South Platte have been 
granted in Nebraska. 

Aoouraoy. — Although the channel ia shifting, sufficient measurements have been 
made to give fairly reliable discharge estimates. 

Cooperation. — During 1911 this station was maintained in cooperation with the State 
engineer.

VOBTK 70BX OF SOITTH VLATTX &ZVXB AT OBAVT, OOLO. 

liocatioii.— At Grant poet office, in sec. 9, T. 7 S., R. 74 W., in the Pike NatLonal 
Forest, 250 feet above the mouth of Geneva Greek. 

Records available.— July 18, 1910, to December 31, 1911. 

Drajna^ area.— 61 square miles (measured from Forest Atlas). 

Gage.— Vertical staff. 

ChazineL — Shifting. 

Discharge measurexnents. — ^Made from footbridge and by wading. 

'^^nter flow. — ^Ice causes backwater during the winter months and measurements 
are made to determine the flow. 

Diversiona. — ^There are no court decrees for diversions from the North Fork above 
the station, but there is a decree for a diversion of 8 second-feet from a tributary. 

Accuracy. — ^Though the channel is somewhat shifting, sufficient measurements were 
obtained to make the estimates reliable. The diurnal fluctuations at this station 
are so great that the mean of two daily readings does not represent the mean dis- 
charge, especially in the spring, when the creek is melting during day and freez- 
ing during night. 

Cooperation. — Statitm maintained in cooperation with the United Stales Forest 
Service.

Aoeuracy. — ^Although the channel is shifting, sufficient measurements have been 
obtained to make the estimates of diachaxge reliable. The diurnal fluctuations 
due to melting during the day and freezing at night are so great at this station 
during the spring and, to a less extent, in the fall, that the mean of two dailygage 
readings does not properly represent the mean stage. 

Cooperation. — Station maintained in cooperation with the United States Forest 
Service and the State engineer.

1911. 

Drainage area. — ^Not measured. 

Qage. — ^Vertical staff; datum unchanged. 

Channel — Unstable, as the flow is frequently affected by backwater from beaver 
dams. 

Discharge measttrementa. — ^Made by wading. 

^i^ter flow. — ^Ice causes backwater during the winter months. 

Diveraiona. — ^No water is diverted above the station, and therefore the records repre- 
sent the natural run-off.

aSHXVA CBXXK AT SITIXXVAirS RAVOH, HXAE aRAVT, COLO. 

Location.— In Pike NationAl Forest in sec. 29, T. 6 S., R. 74 W., 4 miles above Grant, 
at Sullivan's ranch; 40 feet below the mouth of Threemile Creek. 

Records available.-- July 6, 1908, to November 3, 1911. 

Drainage area.— 66 square miles (measured from Forest atlas). 

&age. — ^Vertical staff; datum unchanged. 

Channel. — ^Fairly permanent except during high water. 

Diacharge xneasurexnentB. — Made by wading. 

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

Divendona. — ^There are no court decrees for diversion of water above this station, and 
therefore the records probably represent the natural run-off. 

Accuracy. — Conditions are favorable for good results, and the estimates of diachai^re 
should be reliable. The stream is, however, subject to sharp diurnal fluctuation?, 
especially in the spring and, to a less extent, in the fall, caused by melting during 
the day and freezing at night, so that the mean gage height derived from two daily 
readings may not represent the true stage. 

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

NOTE.— Discharge Apr. 1 to 14 estimated at 6 seoond-feet per day. Nov. 10 to 30 at 7 seoond-feet. 

CLEAR CREEK AT ZDABO BPRZHOfl, COLO. 

Location.— At Idaho Springs, in sec. 36, T. 3 S., R. 73 W., half a mile below mouth 
of Chicago Creek and a quarter of a mile above entrance of Soda Creek and Vir- 
ginia Canyon. "h 

Becords available.— October 8, 1910, to December 31, 1911. 

I>rainag6 area. — 239 square miles (measured from Forest Atlas). 

Qage.— A staff gage placed March 23, 1911 , a short distance upstream from the original 
staff gage, which was used until that date. The new gage was referred to a datum 
0.2 foot lower than the original. All readings have been referred to the latter 
gage. 

Channel. — Slightly shifting. 

Discharge meaBurenients. — Made by wading. 

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

DivendonB.— There are no court decrees for diversions above the station, but the 
records do not represent the natural flow at all times, as water is diverted from 
Eraser River, in the Grand Basin, into Clear Creek by means of a tunnel and 
canal entering the West Fork. This diversion has a court decree for 53 second- 
feet. 

Accuracy. — Conditions are favorable for fairly accurate results. 

Artiflcial control. — ^The operation of two power plants some 12 miles above the sta- 
tion causes a daily fluctuation of 0.10 foot or more at the gage during the low- water 
period. 

Cooperation. — Station maintained in cooperation with the XTnited States Forwt 
Service.

chiefly by the State engineer. The records at the two points are not directly 
comparable, as some water is diverted for irrigation between. From 1902 to 1906 
the records for the lower station were published only in the reports of the State 
engineer.

Location. — At highway bridge in sec. 35, T. 1 S., R. 73 W., 1 mile west of RollinB* 
ville, in the Pike National Forest. The nearest important tributary, Jennie 
Creek, enters 3 miles above. 

Becords available. — September 10, 1910, to December 31, 1911. 

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

Disoharge measurementa. — Made from bridge during high water and by wading 
at ordinary stages. 

Winter flow. — ^Ice causes backwater during the winter months. 

Diversions. — ^There are no court decrees for diversions above the station, and there- 
fore it is probable that the records represent the natural run-off. 

Accuracy. — Conditions are favorable for fairly accurate results and the estimates of 
discharge should be reliable. 

Cooperation. — Station is maintained in cooperation with the United States Forec$t 
Service.

1904, when it was washed out. A second gage was installed at that time, which 
was referred to a different datum. In the spring of 1909 a third gage was installed, 
which was referred to a third datum. 

Chaanel.— Practically permanent except during extreme flood stages. 

Diacharge measurements. — Made from bridge. 

Winter flow.— Ice causes backwater during a portion of the winter months, and 
measurements are made to determine the discharge. 

Diversions.— There is a court decree for a diversion of 198 second-feet from Big 
Thompson Creek above the station. Below, there are decrees for diversioDfl of 
2,624 second-feet from Big Thompson Creek, and flood-water diversions of 24,800 
acre-feet. 

Oooperation. — ^From 1888 to 1890 and subsequent to 1903 this station has been main- 
tained by the State engineer, by whom the records are furnished.

OAOKE LA POXrD&X BIVXK ITBJJl XLXKOUI, OOLO. 

Location. — ^At the lower bridge at Fry's ranch in the southern part of T. 9 N., R. 73 

W.y 7 miles southwest of Elkhom post office. 
Eecords available.— January 6, 1909, to December 31, 1911. 
Draina^ area.— 250 square miles (measured from King's Atlas). 
Oage. — Chain gage; datum unchanged. 
ChanneL — ^Fairly permanent. 
Biflchazige measurements.— Made from bridge. 

Winter flow. — Ice causes backwater during the winter months and frequent meas- 
urements are made to determine the discharge. 
Diversions. — There are no divenions from the Cache la Poudre above the station, 

but the flow is increased by a diversion from Laramie River by the Skyline ditch 

which has a court decree for 400 second-feet. 
Artiflciai oontrol. — The flow is controlled to a certain extent by the reservoir at 

Chambers Lake, which is operated in the interest of irrigation diversions below.

LOTJP &XVEB AT COLTTMBUS, HEBB. 

Location. — At highway bridge in see. 25, X. 17 N., R. 1 W., at ColumbuB, Nebr. 
No tributaries between the station and the mouth of the river 3 miles below. 

BecordB available.— October 13, 1894, to December 31, 1911. 

Drainage area.— 13,500 square miles. 

Gage. — A chain gage installed at the highway bridge Jime 24, 1904, and set to read 
the same as the original vertical staff gage, which was located 1^ miles above the 
bridge and was used from October 13, 1894, to that date. Owing to the slope of 
the river, however, the datum of the chain gage is 8.56 feet lower than that of the 
upper gage.

GhAzineL— Extremely shifting. 

Diflcliazge measurements.— Made from bi^way bridge. 

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

Divendons.— Prior to September 1, 1912, there were approved diversions of 1,7W 
second-feet for irrigation and 4,700 second-feet for i>ower from Loup River above 
the station. There were also approved diversions of 2,046 second-feet for irriga- 
tion and 3,130 second-feet for power, from tributaries entering above. 

Aocoracy.— The extremely shifting channel makes it impossible to make estimates 
of daily discharge without almost weekly measurements, as the gage heights 
afford only an approximate indication of ttte flow. 

CkM>peration. — During 1911 the station was maintained in cooperation with the State 
engineer, by whom the field data were furnished.
