WATER SUPPLY OF ST. MARY AND MILK RIVERS,
1898-1917.
By B. E. Jones and R. J. Burley.
AUTHORIZATION OF WORK.
On January 12, 1918, the Secretary of the Interior suggested to the
International Joint Commission that the commission should arrange
for the compilation and publication of all stream-flow data collected
at both the international and national stations in the Milk and St.
Mary River basins, the data to be agreed upon by the United States
Geological Survey, represented by John C. Hoyt, hydrauhc engineer,
and the Irrigation Branch [now the Reclamation Service] of the
Department of the Interior, Canada, represented by E. F. Drake,
superintendent of irrigation, and to be published in the regular
reports of the commission.
The commission's favorable action on this suggestion was com-
municated to the Secretary of the Interior under date of February
18, 1918, by Mr. Whitehead Kluttz, the secretary of the commission,
who stated that a similar suggestion had been made by the Canadian
superintendent of irrigation.
Under the authority thus conferred on Messrs. Hoyt and Drake,
Mr. B. E. Jones, hydrauhc engineer of the United States Geological
Survey, was directed to compile the records collected in the United
States, and Mr. R. J. Burley, chief engineer, drainage division, of
the Canadian Reclamation Service, was directed to compile the
Canadian records.
SCOPE OF REPORT.
Hydrometric work in the area drained by St. Mary and Milk rivers
was begun in 1897, when the United States Geological Survey
established a station on Milk River at Chinook, Mont. In 1898 this
station was moved to Havre, Mont., about 20 miles upstream. In
Canada records were first collected at a station established by the
Alberta Railway & Irrigation Co. in 1905 on St. Mary River at
Kimball, Alta. Additional stations have been established from
time to time in both countries, and at the end of December, 1917,
recol'ds had been obtained at 79 gaging stations on the main streams
and their tributaries and at 4 1 stations on canals.

10 WATER SUPPLY OF ST. MARY AND MILK RIVERS, 1898-1917.
Most of the records here assem])ied appeal^ as originally published
in the reports of the Reclamation Service of Canada ^ and the United
States Geological Survey, but some have been revised to free them
from errors indicated by later data. The most notable need for
such revisions was m the older estimates of winter flow, many of
which, for stations on Milk E-iver, were based on inadequate data
and have therefore been omitted from the compilation. Tables of
daily discharge not heretofore published have been taken from the
original records.
DEFINITION OF TERMS.
The volume of water flowing in a stream — the '^run-off" or '^dis-
charge"— is expressed in various terms, each of which has become
associated with a certain class of work. These terms may be divided
into two groups — (1) those that represent the rate of flow, as second-
feet, gallons per minute, miner's inches, and discharge in second-feet
per square mile, and (2) those that represent the actual quantity of
water, as run-off in depth of inches, acre-feet, and millions of cubic
feet. The principal terms used in this report are second-feet, second-
feet per square mile, run-off in inches, and acre-feet. They may be
defined as foUows:
'^ Second-feet" is an abbreviation for ''cubic feet per second." A
second-foot is the rate of discharge of water flowing in a channel of
rectangular cross section 1 foot wide and 1 foot deep at an average
velocity of 1 foot per second. It is generally used as a fundamental
unit from which others are computed by the use of the factors given
in the tables of convenient 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.
"Eun-off (depth in inches)" is the depth to which an area would
be covered if all the water flowing from it in a given period were
uniformly distributed on the surface. It is used for comparing
run-off with rainfall, which is. usually expressed in depth in inches.
An "acre-foot," equivalent to 43,560 cubic feet, is the quantity
required to cover an acre to the depth of 1 foot. The term is com-
monly used in connection with storage for irrigation.
The following terms not in common use are here defined :
"Stage-discharge relation," an abbreviation for the term "relation
of gage height to discharge."
"Control," "controUing section," and "point of control," terms
used to designate the section or sections of the stream below the gage
which determine the stage-discharge relation at the gage. It should

be noted that the control may not be the same section or sections at
all stages.
, The '^ point of zero flow" for a given gaging station is that point
on the gage — the gage height — to which the surface of the river
would fall if there were no flow.
EXPLANATION OF DATA.
The base data collected at gaging stations consist of records of
stage, measurements of discharge, and general information used to
supplement the gage heights and discharge measurements in deter-
mining the daily flow. The records of stage are obtained either from
direct readings on a staff gage or from a water-stage recorder that,
gives a continuous record of the fluctuations. Measurements of dis-
charge are made with a current meter by the general methods out-
lined in standard textbooks on the measurement of river discharge.
From the discharge measurements rating tables are prepared that
give the discharge for any stage, and these rating tables, when ap-
plied to the gage heights, give the discharge from which the daily,
montlily, and jearlj mean discharge is determined.
The data presented for each gaging station in the area covered by
this report comprise a description of the station, a table giving results
of discharge measurements, a table shov/ing the daily discharge of
the stream, and a table of monthly and yearly discharge and run-off.
If the base data are insufficient to determine the dail}" discharge,
tables giving daily gage heights and results of discharge measure-
ments are published.
The description of the station gives, in addition to statements re-
garding location and equipment, information in regard to any con-
ditions that may affect the constancy of the stage-discharge relation,
covering such subjects as the occurrence of ice, the use of the or tr earn
for log driving, shifting of channel, and the cause and effect of back-
water; it gives also information as to diversions that decrease the flow
at the gage, artificial regulation, maximum and minimum recorded
stages, and the accuracy of the records.
The table of daily discharge in general gives the discharge in
second-feet corresponding to the mean of the gage heights read each
day. At stations on streams subject to sudden or rapid diurnal iTuc-
tuation the discharge obtained from the rating table and the mean
daily gage height may not be the true mean discharge for the day.
If such stations are equipped with water-stage recorders tlio mean
daily discharge may be obtained by weigliting discharge for parts of
the day.
In the table of monthly discharge the coUimii hejicied "Maximum"
gives the mean flow for tlie day when th(^ menu gage heiglit was
highest. Ab the gage height is the mean for the day it does not
12 WATEK SUPPLY OF ST. MARY AND MILK ER^ES, 1898-1917.
indicate correctly the stage when the water surface was at crest height
and the corresponding discharge was consequently larger than given
in the maximum column. Likewise, in the column headed ^'Mini-
mum" the quantity given is the mean flow for the day when the mean
gage height was lowest. The column headed '^Mean" is the average,
flow in cubic feet for each second during the month. On this average
flow computations recorded in the remaining columns, which are
defined on page 10, are based.
ACCURACY OF STREAM-FLOW DATA.^
By N. C. Grover and J. G. Hoyt.
DEGHEE OF ACCURACY REQUIRED.
The laws relating to many natural phenomena have been reduced,
to an exact science; those for many more are largely empirical and
are based on experiments and assumptions that only approximate the
truth. In the empirical class are included the laws of the science of
hydrology and especially of that branch of hydrology which relates
to the flow of water in open channels. It is possible, nevertheless^
by carefully considering the various factors, to reduce the incidental
errors so that resulting records will be sufficiently accurate for tha
purposes for which stream-flow data are required.
In most problems two degrees of accuracy must be considered-
first, that which is practicable or possible to obtain, and, second, that
which is desirable or necessary. The obtainable accuracy of stream-
flow data depends largely on the amount of money available for their
collection. The desirable accuracy depends on the proposed use of
the data.
Stream-flow records have three principal uses — first, in predicting
flow, generally in connection with the design of hydraulic works;
second, in the immediate operation of hydraulic works; and, third,
in studying conditions of past flow, usually in connection Vvdth the
adjustment of water rights. For the second and third uses data as
accurate as can be collected may be needed. In considering the
first use, however, it should be remembered that both the total flow
of a stream and its regimen change from year to year, and that the
conditions existing at any particular time may never recur. For
this use, therefore, reasonably accurate records that extend over a
considerable period are much more valuable than extremely accurate
data covering a short period.
Studies of the accuracy of stream -flow data serve to determine the
methods to be followed in their collection so that the records may
meet the requirements of the proposed uses. Notes on accuracy that
accompany stream-flow records should give, first, information by
J Republished from Contributions to the hydrology of the United States, 1916: U. S. Geol. Survey
Water-Supply Paper 400, pp. 53-59, 1916.
•WATEE SUPPLY OF ST. MAEY AND MILK EIVERS, 1898-1917. 13
which the technical man may study the records and judge their ac-
curacy, and, second, information by which both the general and the
technical user may judge the reliability of the records without mak-
ing a study. These two uses should be kept in mind in preparing the
data as well as the notes. Consideration of the accuracy of records to
be collected at any station should begin with the reconnaisance for
the site and continue through the selection, establishment, mainte-
nance, and operation of the station, the computation and interpreta-
tion of the data, and the preparation of the records for publication.
In other words, records should be collected with the desired degree
of accuracy in view instead of leaving it to be determined after the
field data are collected and estimates have been made.
In this discussion of accuracy it has been assumed that personal or
instrumental errors, both in field and office, are reduced to a negli-
gible amount. In order that this assumption may be true, however,
all operations connected with the work must be carefully conducted
and instruments must be kept in proper working order.
The conditions affecting accuracy may introduce errors that may
be consistently compensating, consistently cumulative, or alternately
compensating and cumulative. Therefore care must be taken to de-
termine the way in which the incidental errors affect the results.
CONDITIONS AFFECTING ACCURACY OF BECORDS OF DAILY
DISCHARGE.
The obtainable accuracy of records of daily discharge of a stream
depends on the following factors, information in regard to which
will determine the methods of operation and give a basis for evaluat-
ing the records after they are collected:
1. Permanence of the stage-discharge relation.
2. Precision with which the discharge rating curve is defined.
3. Refinement of gage readings.
4. Frequency of gage readings.
5. Methods of applying the daily gage heights to the rating table
to obtain the daily discharge.
Permanence of the stage-discharge relation. — The permanence of
the relation of discharge to stage as determined by the control is a
fundamental factor in the collection of records of daily discharge of
a stream. It may be disturbed either by a cliange in the control
itself or by conditions that counteract the effect of the control, such
as backwater from log or ice jams or floods in tributary streams
below the station. The general character of the control and the con-
ditions that may affect it are determined by inspection. The effec-
tiveness of the control, however, can be finally determined only by
plotting the results of discharge measurements. If sucli })lotting
does not define a smooth curve the inconsistenc}'^ is duo to poor
14 WATEE SUPPLY OF ST. MARY AI?fD MILK RIMERS, 1898-1917.
current-meter measurements of discharge, to instability of the con-
trol, or to disturbing influences. If the control is unstable the ac-
curacy of the record will depend on the number of the discharge
measurements and their distribution as to time and stage.
Errors due to lack of permanence of the stage-discharge relation
may be either compensating or cumulative, according to the physical
conditions affecting the nature and stability of the control.
Precision of the disch<irge rating curve. — The precision with which
the discharge ratmg curve is defined depends on the accuracy of
the discharge measurements, their distribution in range, and the per-
manence of the control. If the relation of the (discharge to stage
were permanent and truly defined by the rating curve and the dis-
charge measurements were absolutely accurate a series of measure-
ments for a station would plot on a smooth curve. Unfortunately,
such ideal conditions do not exist; therefore, a series of measure-
ments for a station will plot somewhat discordantly, and the rating
curve should be drawn among them in such a way as to represent aver-
age conditions. For permanent conditions of control combined with
a good measuring section the variations of individual measurements
from the mean curve should be compaTatively small and as likely
to be plus as minus. The probable error of a rating cm?ve may be
computed by the method of least squares and will be a factor in
determining the probable error of the estimates of daily discharge.
Errors in determinations of daily discharge resulting from errors
in the position of the rating curve will be cumulative for any stage,
but may be partly compensating if the curve used lies first on one side
and then on the other side of the true curve.
Refinement of gage readings.— RGG.n&DAent of gage readings affects
the accuracy of stream-flow data to a degree dependent on the
sensitiveness of the station, which in turn is determined by the size
and shape of the channel at the control in relation to the quantity
of discharge. The sensitiveness is indicated b}^ the magnitude of the
change in stage accompanying a given change in discharge. The
limiting requirements as to sensitiveness should be a change in stage,
that is readable on the gage used for a change of 1 per cent iii dis-
charge. In general the more sensitive the station the more accurate
the records that can be collected by ordinary methods and the less
refinement necessary in the gage readings.
Errors due to lack of refinement in reading will generally be com-
pensating, but they may be cumulative when the stage shows only
small fluctuations during a considerable period or when they are
due to systematic personal errors of the observer.
The degree of refinement in record of stage necessary to give a
sufliiciently accurate determination of discharge will vai*y inversely

with, the stage and is determined by the sensitiveness of the station
* as disclosed by a study of the discharge rating curve.
Gages are usually read to hundredths, quarter-tenths, half -tenths,
or tenths. The resulting absolute errors of observations in individual
readings are shown by the following table :

For staff and chain gages 2 per cent has been selected, more or less
arbitrarily, as the limit of allowable average error in a determination
of daily discharge due to errors in the determination of mean daily
gage height. The table indicates that the maximum error for any
ono day is twice the average error, so that the maximum error for
any one day may be 4 por cent. According to the law of probabilities
the average error in the determination of a monthly mean discharge
for fluctuating stages resulting from a 2 per cent average error in
the determination of mean daily discharge is about one-third of 1
per cent.
The refinement to which the records of mean daily gage height
must be used — whether to hundredths, half-tenths, or tenths — in
order to obtain this limit of accuracy in determinations of discharge
at any given stage will depend on the percentage of difference in dis-
charge for such least differences in gage readings at that stage, as
shown by the rating table.
In determining this refinement the engineer should proceed as
follows and enter the results in a table of the form given below, in
which the Potomac at Point of Rocks, which is read once daily to
hundredths, is used as an example.

The discharge rating table shows that the minimum discharge is
580 second-feet and occurs at gage height 0.4 foot. The difference
per tenth between gage heights 0.4 and 0.5 foot is 210 second-feet,
or 36.2 per cent of the minimum discharge.
The hmits of stage between which it is necessary to use mean daily
gage heights to hundredths, half-tenths, and tenths, respectively,
in order not to introduce an average error of over 2 per cent in the
determination of daily discharge are shown in the last three columns
and are determined by trial by testing values from the discharge
rating table at selected haK-foot intervals, as follows:
In testing at the 2-foot gage height for gage records to tenths the
difference between the discharge at 2.0 feet and that at 2.1 feet is
found to be 360 second-feet. The average error of a mean daily rec-
ord to tenths is one-fourth tenth. Therefore at gage height 2.0 feet
the average error for such record, expressed in second-feet, is -2^ = 90
second-feet, which is 1.8 per cent of 5,020 second-feet, the discharge
at the 2-foot stage. Therefore it is not necessary to use gage-height
records closer than 0.1 foot- above the 2-foot stage, as above this stage
the average error is less than 2 per cent, which is the allowable error.
A continuation of this analysis shows that in order to keep the
error in the determination of discharge resulting from lack of refine-
ment in gage readings below 2 per cent, the gage at Point of Eocks
should be used to hundredths below the 1-foot stage, to haK-tenths
between 1.0 foot and 2.0 feet, and to tenths above 2.0 feet.
For a record obtained with a water-stage recorder the same pro-
cedure is f ollov/ed except that the allowable error should be 1 per
cent.
For stations T^'ith shifting control the methods of analysis above
described can be used only in a general way.
In practice the limits of use of gage heights can be readily deter-
mined by the following rules:
Find the stage at which the difference in discharge per tenth is
8 per cent of the discharge at that stage. Gage heights above this
stage should be used to tenths.
Find the stage at which the difference in discharge per tenth is
16 per cent of the discharge at that stage. Gage heights below this
stage should be used to hundredths.
Gage heights between the two stages thus found should be used
to half-tenths.
Frequency of gage readings. — The frequency of gage readings is
an important factor in the accuracy of records of streams that are
subject to considerable daily fluctuation in stage. To obtain a gage
record so accurate that its use with the fating table wiU give the
true mean discharge for the day the number of readings should vary,
according to the nature of the fluctuations, from one or two daily to
a continuous record obtained by some form of water-stage recorder.
WATER SUPPLY OP ST. MARY AND MILK RIVERS^ 1898-1917. 17
To ascertain the frequency required it is necessary to compare the
daily discharge obtained from one gage reading daily or the mean of
two readings daily with that obtained from the mean of hourly gage
heights or by a discharge integrator.
Errors due to insufficient gage readings may be cumulative or com-
pensating, or alternately one and the other, according to the nature
of the fluctuations in stage.
Methods of applying the daily gage heights to the rating table, —
The method of applying daily gage heights to the rating table to
ascertain mean daily discharge is determined by the curvature of the
rating curve.
Theoretically, the mean daily discharge of a stream is the mean of
the discharge for every second during the day. In ordinary compu-
tation of daily flow, it is assumed that the rate of discharge through-
out the day varies so little or with such regularity that the daily dis-
charge may be determined by entering a rating table with a mean
daily gage height obtained either from a few observations or from a
continuous record made by a water-stage recorder. As discharge is in
general an increasing curvilinear function of gage height, the use
of a mean daily gage height with a rating table gives a result that
is always too small. The magnitude of this error, which wiU vary
with the curvature of the rating curve and with the daily range in
stage, will determine whether the daily discharge can be ascertained
directly by finding a mean daily gage height or indirectly by averag-
ing the discharge corresponding to gage heights for shorter inter-
vals. Hourly discharge is frequently used. As an ultimate limit the
absolute mean discharge for the day may be ascertained by a dis-
charge integrator, which operates much as a planimeter operates and
contains as an essential element the rating curve of the station. Such
an integrator has been devised by E. S. Fuller, formerly assistant
engineer, United States Geological Survey.
It is necessary, therefore, to study each gaging station, in order to
determine the length of the period that should be used in applying
the gage heights to the rating table. In such an investigation a
maximum allowable error of 1 per cent is assumed. The amount of
daily range in stage allowable for a given mean daily stage,^ in order
that errors due to curvature of the rating curve shall not exceed 1 per
cent, can be found graphically by constructing a chord to the rating
curve such that the horizontal distance, measured by the clischarge
scale, from its middle point to the curve equals 1 per cent of the dis-
charge at the gage height of the middle poitit. Tlio difference in
gage height at the ends of the chord will be the allowable daily
range.

18 WATER SUPPLY OF ST. MARY AND MILK RI^^RS, 1898-1917.
A table of such limits covering the range of stage, used with tables
of mean daily stage and range in stage, will indicate the days for
which the mean daily discharge can be found directly from the mean
daily gage height and those for which more frequent intervals are
necessary.
The errors resulting from the application of the gage height to the
rating table will in general be cumulative, and their magnitude will
vary with the method used in making the computations.
ACCTJIIACY OF MONTHLY OR YEARLY MEANS.
The foregoing discussion of accuracy relates only to determina-
tions of daily discharge. For many uses the mean flow for longer
periods may be sufficient. The monthly mean is in general use for
hydraulic studies. If errors resulting from all causes in the esti-
mates of daily discharge are compensating, the probable error in the
determination of mean monthly discharge will be much less than
the probable error of the individual determinations of daily dis-
charge. A careful analysis of the estimates of daily discharge and
monthly means computed from them shows that large errors m the
dady estimates may be so compensated that the errors in the monthly
means are small.
ST. MARY RIVER BASIN.
GENERAL FEATURES.
St. Mary River rises in northwestern Montana, on the eastern slope
of the Continental Divide (PL I), in a region of perpetual snow and
ice. The stream flows out of the Blackfeet Glacier, probably the
largest in the Rocky Mountains within the United States, and is
joined by at least a dozen lesser streams that unite within a short
distance of their sources. The combined waters flow into a lake
which is hemmed in by lofty mountains and is known as Upper St.
Mary Lake. A short stream through a narrow strip of land connects
this lake with Lower St. Mary Lake, the total length of the two being
22 miles.
The river and all its tributaries except Boundary Creek on the
west side and Rolph (Willow), Pinepound, and Pothole creeks on the
east side rise in the main range of the Rocky Mountains, where the
mean annual precipitation amounts to about 60 inches, and occurs
in greater part as snow. Although comparatively small, this moun-
tainous part of the basin furnishes practically all the water. The
stream is subject to great fluctuation during the summer, furnishes
water throughout the irrigation season, and maintains fairly constant
though low flow during the winter.
WATER SUPPLY OF ST. MARY AND MILK RIVERS^ 1898-1917. 19
Altitudes in the drainage basin in the United States range from
4,000 to 10,000 feet above sea level, and the fall of the river is com-
paratively rapid throughout its course, especially between the St.
Mary Lakes and the Alberta Railway & Irrigation Co.'s intake. The
elevation of the water level of the river at various points is shown by
the following table:

In the upper part of the stream valley below St. Mary Lakes the
banks on the west side of the river are, as a rule, gently sloping, but
on the east side cut banks of clay and sandstone occur at a number of
places as far down as the crossing of the United States Reclamation
Service siphon west of Spider Lake, where a valley extends eastward
into the drainage basin of Rolph or Willow Creek. Below this pomt,
almost to the intake of the Alberta Railway & Irrigation Co.'s canal,
the valley banks are high and in many places precipitous, especially
through T. 1 in Canada, but from this point to about the center of
T. 4 the valley is wider and the slope of the banks is much gentler
From here on the stream flows for some distance in a deep, narrow
canyon walled by almost perpendicular banks made up of clay with
layers of sandstone. Below the canyon, though the valley is wider,
there are numerous cut banks of clay and sandstone that effectually
preclude the possibility of diversion for irrigation. If reasonable
cost is a consideration, the diversion of water from this river for use
on the bench lands at any point much below the south boundary of the
Blood Indian Reserve appears to be impracticable.
From the Sfr. Mary Lakes to the canyon in T. 4 the bed of the stream
is composed of gravel and boulders and the banks are almost entirely
of sand and gravel. A bed of gravel and boulders is, iiukHnl, charac-
teristic of the stream, although there is more rock and the boulders are
larger in the lower reaches, where also the water is more turbid, prob-
ably because of material washed from the clay banks along this
portion of its course.
In the upper part of the stream, where the grade is high, there are
in places several channels separated by gravel banks, l)ut lower
down the stream appears to be confined to one channel and withiu
well-defined banks.
20 WATER SUPPLY OF ST. MARY AND MILK RIVERS,. 1898-1917.
The stream valley is practically unforested north of the mouth of
Swiftcurrent Creek, and though aspen, willow, and poplar grow
sparsely above this point, the growth is not sufficient to be com-
mercially valuable.
The principal tributaries of the St. Mary are Smftcurrent, Kennedy,
and Lee creeks.
Swiftcurrent Creek rises near the Continental Divide and is fed by
streams from Grinnell Glacier, Iceberg Lake, and several small,
unnamed lakes. The first lake worthy of note is McDermott, which
receives the drainage froin an area comprising 31 square miles, prac-
tically all mountainous. The stream flowing from McDermott Lake
passes by a fall and cataract about 80 feet high to the valley below,
which spreads out to a width of about a mile and has comparatively
little fall to the mouth of lower Sh'erburne Lake. A contraction of
the valley at this point forms the site of the Sherburne Lake dam
which, when completed, will back the water nearly to the foot of the
McDermott falls. The only important tributary between McDer-
mott Lake and the mouth of Sherburne Lake is Canyon Creek, the
drainage area of which at the gaging station near the mouth com^prises
7 square miles. Boulder Creek, the chief tributary of Swiftcurrent
Creek, enters about 3 miles above the mouth. On October 1, 1915,
Swiftcurrent Creek was diverted into Lower St. Mary Lake by a dam
at the point where it leaves the mountains, about 2 miles above its
former mouth.
Kennedy Creek, flowing into the St. Mary from the west, is in many
respects similar to Swiftcurrent Creek, and although smaller, adds
materially to the flow of the river. It rises in the mountains between
the head of Swiftcurrent Creek and Chief Mountain. Its catchment
area is small, but the run-off per square mile is large.
Lee Creek rises on the northern slope of Chief Mountain, crosses the
international boundary some distance west of the St. Mary, and
after flowing about 15 miles through Canadian territory joins the river
east of Cardston. Its flow is large during the spring and early summer
but decreases rapidly during the rest of the year, and through the
winter months it carries little more than enough water to supply the
domestic needs of the settlers along its banks and the municipal
requirements of the town of Cardston.
The tributaries on the east side of the river — Rolph or Willow Creek,
Pinepound Creek, and Pothole Creek — rising as they do in the foot-
hills or on the Milk River Ridge, are unimportant and can not be
depended on to supply even the domestic needs of the residents along
them.
Boundary Creek, rising in the foothills between Lee Creek and St.
Mary River and flowing in on the west side immediately south of the
boundary, is similar in all respects to the creeks last mentioned.

ST. MARY RIVER NEAR BABB, MONT.
Location.— In Sec. 27, T. 36 N., R. 14 W., 1,040 feet above the headworks of St.
Mary canal and about 2 miles south of Babb, on Blackfeet Indian Reservation, in
Teton County. (See PI. II, A.)
Drainage area. — 278 square miles, including area of Swiftcurrent Creek above point
of diversion into Lower St. Mary Lake; prior to October 1, 1915, 177 square miles.
Records available. — April 9, 1902, to December 31, 1917. Records subsequent to
October 1, 1915, are comparable with those obtained at gaging station below
mouth of Swiftcurrent Creek pre^dous to that date. (See Regulation.)
Gage. — Chain gage on right bank; a temporary low-water gage about 30 feet out in
the stream is used during the winter months. Gages are read by employees of
the United States Reclamation Service.
Discharge measurements. — Alade from a cable 560 feet below the gage or by wading
about 800 feet below the gage. In September, 1909, the cable was moved from a
point 300 feet downstream.
Channel and control. — Original stream channel practically permanent. Banks
high and not subject to overflow. In 1916 construction work by the United
States Reclamation Service on the St. Mary canal diversion dam, 1,040 feet below
the gage, caused changes in the stage-discharge relation. This dam, which at
present forms the principal control, is provided with flashboard sluice gates, but
these are seldom changed. The St. Mary canal takes water from the left side of
the dam. A gaging station is maintained at the head of the canal to determine
the quantity of water diverted and discharge measurements show the effect of
these diversions on the stage-discharge relation.
Extremes of discharge. — Maximum stage during period covered by records esti-
mated at 9.4 feet June 5, 1908 (discharge, 7,980 second-feet); minimum stage
recorded, 1.0 foot April 3-7, 1904 (discharge, 20 second-feet).
Ice. — Stage-discharge relation may be affected by ice during January, February, and
March, but the effect is usually small.
Diversions. — ^About ,200 acres of hay land is irrigated by water diverted from
Swiftcurrent Creek above this station.
Regulation. — The flow of Swiftcurrent Creek, which is regulated to a small extent
by Sherburne Lake reservoir, was diverted into St. Mary River October 1, 1915.
Accuracy. — Stage-discharge relation affected by shifting of control at low water, by
placing or remo\dng flashboards on dam, and by diversions into the United States
Reclamation Service St. Mary canal. The effect of thcwse influences can be
closely determined from the discharge measurements and the observer's notes.
Records good.

^ OTE.— Mean discharge for January, February, March, and December, 1908, has been revised, as observer
read the gage in inches. Channel open part of February and March; determinations good. For January
the record is fair. Discharge Apr. 1-8, 1902, estimated.
Staj^'e-discharpe relation affected by ice and discharge estimated for following periods: Jan. 1 to Mar. 31
and Dec. 1-31, 1902; Dec. 11-31, 1903; Jan. 1-10 and Jan. 20 to Apr. 2, 1904; Jan. 1 to Mar. 1 and Nov. 26 to
Dec. 31, 1905; Jan. 1 to Feb. 19 and Mar. 11-25, 1906; Jan. 1 to Mar. 31, 1907; Jan. 1 to Mar. 31 and Nov. 2i;
WATER SUPPLY OF ST. MARY AND MILK RIVERS, 1898-191*7. 31
to Dec. 31, 1908; Jan. 1 to Mar. 12 and Dec. 25-31, 1910; Jan. 10 to Feb. 7 and Feb. 19 to Mar. 3, 1911; Jar.
1-5, 1912; Feb. 6-20, Dec. 1-19, 1913; Dec. 5, 1916, to Jan. 5, 1917; Jan. 21, 29-31; Feb. 1, 16-28; Mar. 1-11,
1917.
See table of monthly discharge for estimates of mean flow for full months.
Estimates of discharge for periods of less than one month, not shown on table of daily discharge, were as
follows: Mar. 1-12, 1910, 120 second-feet; Jan. 10 to Feb. 7, 1911, 100 second-feet; Feb. 19 to Mar. 3, 1911, 80
second-feet; Feb. 6-20, 1913, 75 second-feet; Dec. 1-19^ 1913, 140 second-feet. Daily and monthly discharge
recomputed Apr. 1, 1904 to May 31, 1905. The origmal estimate of mean discharge for March, 1907, was
revised by means of discharge measurements Mar. 20 and 30 of that year.
From Jan. 1 to some time in April, 1909, and Nov. 23 to Dec. 31 of the same year, stage-discharge relation
affected by ice, but no estimates were made except Nov. 23-30, when the open-channel rating curve was
used. Rough estimates of monthly means were based on weekly gage heights and open-channel rating
curve. These means are given in the table of mean monthly discharge but were not considered sufficiently
accurate to be included with the computed records for the year. The records for 1909 are, in general, un-
satisfactory, as they do not check the results obtained on Swiftcurrent Creek near Babb, nor those on St.
Mary River at Cook's ranch.
In the previously published records for 1911 the daily discharge for Feb. 14 was given as 4 second-feet,
with a note stating that this low stage was probably due to the water being held baok by the ice at the
outlet of St. Mary Lake at the time the gage-height observation was taken and that the discharge for the
day was probably considerably greater. The discharge for Feb. 14, 1911, therefore, has been estimated at
46 second-feet, which is the same as the discharge on Feb. 13 and 15.
Jan. 1 to Mar. 25, 1912, ice present in stream, but open-channel rating was assumed applicable except
Jan. 1-5, which was estimated.
Oct. 1, 1915, Swiftcurrent Creek was turned into St. Mary Lake above the gage. Discharge Nov. 1-10,
1915, estimated at 70 per cent of flow at Kimball. Dec. 20-31, 1915, estimated mean 145 second-feet, or
approximately CO per cent of flow at Kimball.
Jan. 1-18, 1916, mean flow estimated 90 second-feet from flow at Kimball.

Note.— Oct. 1, 1915, Swiftcurrent Creek was diverted into St. Mary Lake above this station, and the dis-
charge thereafter is not included in the above table because not comparable with the discharge previous to
that date. The median flow given was obtained by arranging the monthly means in their order of magni-
tude and taking the middle mean, or, if their number was even, the average of the two middle means. By
using daily discharge a somewhat lower median discharge would be obtained.
ST. MARY RIVER BELOW SWIFTCURRENT CREEK, AT BABB. MONT.
Location. — In sec. 15, T. 36 N., R. 14 W., about a mile below mouth of Swiftcurrent
Creek, at Babb, on Blackfeet Reservation, in Teton County.
Drainage area.— 298 square miles.
Records available.— July 14, 1901, to October 18, 1902; May 13, 1910, to September
30, 1915, when station was discontinued.
Gage. — Stevens water-stage recorder on right bank opposite Babb post office. From
July 14, 1901, to October 18, 1902, a staff gage on the left pier of a highway bridge
about 100 feet above the location of the water-stage recorder, and at a different
datum, was used; this gage was destroyed by the flood of June 5, 1908. From
May 13, 1910, to July 18, 1911, a staff gage was maintained on the left bank about
75 feet below the original gage and at a different datum ; a temporary chain gage
was used for low-water readings. From July 19, 1911, to April 21, 1915, an over-
hanging chain gage was maintained on the right bank at the same datum and
location as the water-stage recorder and at the same datum as the staff gage on left
bank, but on account of conditions in the channel the gages on opposite banks
did not read the same. Beginning January 1, 1913, separate gaging stations were
maintained on St. Mary River and Swiftcurrent Creek overflow, and the results
at the t^^'o stations were added to give the total flow of the river at Babb ; previous
to that date only the gage on St. Mary River was read, the discharge of the overflow
being included in discharge measurements. As the discharge of the overflow
was a small part of the total flow and varied with the flow of Swiftcurrent Creek,
ceasing entirely at low stages, only a small error resulted from this proi^odiiro.
DiscHAR(rE measure.ments. — Made from the cable 50 feet above gage or by wading.
Small overflow channel from Swiftcurrent Creek measured from a 'footbridge.
Channel and control. — Bed of stream composed-of gravel and cobblostoiu^s; shifts
slightly. A small overflow channel from S\\iftcurrent Creek enters about 100
feet below gage on left bank.
ExTRHMEH oi' DiwHAHOK. — Maximum stago recorded, 6.5 feet July 4, 1902 (discharge,
f),C)90 second-feet); minimum stage recorded, 3.48 feet March 15-25, 1912 (dis-
charge, M second-feet).

Note.— Dec. 29, 1910, and Mar. 15, 1911, ice at gage.
1911: July 19, new gage installed on bank opposite gage previously used and at new datum.
1914: Dec. 16, ice at gage but probably not enough to cause backwater.
Discharge measurements beginning Mar. 16, 1912, do not include the overflow from Swiftcurrent Creek,
which was computed separately; previous to that date the main river and overflow were combined in
measurements and computations.

Note. — 1901 : Determinations of daily discharge for November and December revised slightly by making
rating curve for 1901 agree with curve for 1902 below gage height 0.50 foot.
1902: Daily discharge for January, February, and March ascertained by appljdng open-channel rating
curve to observed gage heights; results may be somewhat high but the error is probably not great though
WATER SUPPLY OF ST. MARY AND MILK RIVERS; 1898-1917. 41
the discharge for February appears to be about 50 second-feet too large. Determinations of discharge Sept.
22 to Oct. 18, 1902, have been revised as original computations were based on incorrect gage readings.
1910, Dec. 24-31: Ice present at gage but open- water rating curve assumed applicable.
1911: Stage-discharge relation affected by ice Jan. 1 to Mar. 3 and Dec. 26-31; mean discharge Mar. 1-3
estimated at 95 second-feet and Dec. 26-31 at 65 second-feet. See table of monthly discharge for estimates
for January and February.
1912: Stage-discharge relation affected by ice Jan. 1 to Feb. 5; discharge estimated as follows — Jan. 1-12,
80 second-feet; Jan. 13 to Feb. 6, 110 second-feet.
1913: Stage-discharge relation affected by ice Feb. 6-24; discharge estimated at 150 second-feet.
1914: Stage-discharge relation affected by ice Jan. 1 to Feb. 28; discharge estimated. Daily discharge
also estimated for following periods, on account of unreliable gage readings due to disturbance of gage by
high water: May 2-7, June 8-16, June 22 to July 20, Aug. 1-16, Aug. 21 to Sept. 17, Oct. 8-15, 21-31, Nov.
1-6, 23-30, Dec. 1-9 and 24-26.
1915: Stage-discharge relation affected by ice Feb. 10-18; discharge estimated. Oct. 25, previously pub-
lished discharge believed to be high and has been revised by comparison with stations near Babb and
near Kimball.

Note.— 1901-1902 and 1910 to Sept. 30, 1915, discharge obtained from records of St. Mary River below
Swiltcurrent Creek at Babb. On Oct. 1, 1915, Swiftcurrent Creek was diverted into St. Mary Lake, and
from that date on the records on St. Mary River near Babb were used. The run-off at the two points is
nearly identical, Duck Creek being the only tributary between. In computing means for the period of
record the means for the three partial months were considered the means for full months. The median
flow given was obtained by arranging the monthly means in their order of magnitude and taking tho
middle mean, or, if their number was even, the average of the two middle means. By using daily dis-
charge a somewhat lower median discharge would be obtained.
ST. MARY RIVER AT COOK'S RANCH, ALT A., NEAR INTERNATIONAL BOUNDARY.
LocATiox. — In SE. ^ sec. 6. T. 1 N., R. 25 W. fourth meridian, at Cook's ranch,
half a mile north of the international boundary, about a mile below the mouth
of Boundary Creek, and 17 miles southeast of Cardston, Alta., Canada.
Drainage area. — 452 square miles.
Records available. — September 4, 1902, to December 31, 1912. The station was
then moved to a point near Kimball, about 8 miles downstream, and a joint
intei'iiational station was established. The discharge at the two points is prac-
tically the same.
Gage. — An overhanging chain gage fastened to a tree on the left bank, a quarter of
a mile below Cook's house. From September 4, 1902, to June, 1908, an over-
hanging gage about one-fourth mile upstream was read; this gage was washed out
by the flood in June, 1908, and replaced July 27, 1908, at the new site.
Discharge measurements. — Made from a cable one-fourth mile above gage.
Channel and control. — Bed of stream is composed of gravel of medium size.
Rapids just below gage; current swift at practically all stages. The banks not
subject to overflow except during extreme floods, but the left bank is gently
sloping, so that the stream is probably 200 to 300 feet wider at high than at low
stages.
Extremes of discharge. — Maximum stage recorded, 12.75 feet June 5, 1908 (dis-
charge, estimated by comparison with record for station near Babb, 18.000 second -
feet); minimum stage recorded November 19, 1904 (discharge by current-myter
measurement 96 second-feet). Lower stages probably occurred during the
winter months for which records of daily discharge are uot available. (See
hydrograph, PI. III.)
Ice. — Stage-discharge relation seriously affected by ice during winter montha.
Diverson. — None during the period of this record.
Regulation. — None.
44 WATER SUPPLY OF ST. MARY AND MILK RIVERS, 1898-1917.
Accuracy. — Stage-discharge relation not permanent; affected by shifting control and
ice. Records for 1909 do not agree with records obtained by Canada at Kimball,
being from 10 to 37 per cent lower. They also appear low when compared with
combined flow of St. Mary River above Swiftcurrent Creek and Swiftcurrent
Creek; but current-meter measurements by W. A. Lamb made at Kimball, Alta.,
are much lower than the results obtained by Canada. Records at all four stations
for 1909 should be used with caution. Records for October, November, and
December, 1903, and June to November, 1904, appear low when compared .with
the combined flow of St. Mary River above Swiftcurrent Creek and Swiftcurrent
Creek. It is impossible to determine where the error lies, but as it is not very
great it was thought best to base computations of the run-off at each station on
the data obtained at that station. Considered as a whole the record is fair.

5 to Apr. 10, 1904; Jan. 1 to Mar. 4, and Dec. 1-31, 1905; Jan. 1 to Mar. 31, 1906, 1907, and 1908; Dec. 9-31, 1908,
Jan. 1 to Apr. 22, and Nov. 21 to Dec. 31, 1909; Jan. 1 to Mar. 13, 1910; Jan. 1 to Mar. 31, Nov. 10-16. and
Dec. 16-31, 1911; Jan. Ito Apr. 2, and Dec. 12-31, 1912; discharge estimated for these periods as follows:
Mar. 1-4, 1905, 171 second-feet; Mar. 1-13, 1910, 180 second-feet; Dec. 12-31, 1912, 210 second-feet. Discharge

Dec. 9-31, 1909. For estimates of flow for other periods see tables of daily and monthly discharge.
Determination originally pubUshed for Dec. 1-31, 1902, and Jan. 1 to Apr. 12, 1903, obtained by applying
an open-channel ratine table; these results have been discarded and the mean monthly discharge estimated
from the records of flow of St. Mary River above Swiftcurrent Creek and Swiftcurrent Creek near Babb.
The mean flow Apr. 1-12, 1903, was estimated at 200 second-feet. Jan. 1 to Feb. 4, 1904, and Dec. 9-31,
1906, ice present at gage, but open-channel rating curve assumed applicable.
Jime 1. 1904, to Apr. 30, 1905, daily discharge recomputed.
Dec. 14-31, 1907, gage heights missing and daily discharge estimated. Gage and cable washed out by
high water June 5, and replaced July 27, 1908; determinations of discharge for this period based on results
at Babb. No gage heights reported Apr. 28-30, Aug. 1 to Sept. 17, and Sept. 26 to Oct. 13, 1909; estimates
for these periods not made.

ice and discharge estimated and for periods for which the published discharge has been revised. Published
monthly mean May, 1903, revised slightly to correct for error in addition.
WATER SUPPLY OF ST. MARY AND MILK RIVERS, 1898-1917. 53
ST. MARY RIVER NEAR KIMBALL, ALT A., NEAR INTERNATIONAL BOUNDARY.
Location. — In the SW. ^sec. 25, T. 1, R. 25 W. fourth meridian, about 1 mile south-
west of Kimball post office, 1 mile southwest of the head gates and dam of the
Alberta Railway & Irrigation Co.'s canal, and 14 miles southeast of Cardston,
Alta. (See PL II, B.)
Drainage area. — 472 square miles.
Records available. — April 13, 1908, to December 31, 1917.
History. — Station was originally established in 1905, by the Alberta Railway & Irri-
gation Co., in the SW. i sec. 25, T. 1, R. 25 W. of the fourth meridian, about half
a mile above the company's head gates. It was taken over by the Irrigation
Branch, Department of the Interior, Canada, in April, 1908."
Owing to lack of sufficient measurements and to the great changes in the channel
and control caused by the flood of June, 1908, it has been found impossible to
determine the discharge of the stream previous to June 21, 1908, although the gage
heights are available for the intervening period.
The United States Geological Survey maintained a station on the St. Mary a
short distance north of the international boundary, for which records of flow are
available from 1902 to 1912 and are included in this report under the heading "St.
Mary River at Cook's ranch, near international boundary."
In 1912 it was decided to combine these stations, provide the best possible
equipment, and maintain and operate them jointly. A site was selected and a
concrete gage house, equipped with a Stevens continuous water-stage recorder,
was installed. This new station was used until the fall of 1916, when the forma-
tion of gravel bars made it necessary to remove the equipment to a new site
about half a mile farther up stream. A new cable station was erected above the
new gage house and measurements have been made from it during the season of
1917.
Gage. — Stevens water-stage recorder in frame shelter over concrete well, with vertical
staff gages inside and outside well; winter readings obtained from a chain gage
attached to a traffic bridge in SW. I sec, 1, T. 2, R. 25 W. fourth meridian.
From 1908 to 1912 gage used was a staff in the NE. i sec. 25, T. 1, R. 25 W.
fourth meridian ; from 1913 to 1916 the water stage recorder was in the NW. i sec.
25, T. 1, R. 25 W. fourth meridian. Observer for all gages, J. M. Dunn.
Discharge measurements. — Open- water measurements made from cable 1,500 feet
above gage ; winter measurements made from traffic bridge to which chain gage
is attached.
Channel and control. — Banks high and rocky; not subject to overflow. Bed com-
posed of gravel and rock. Control formed by a ledge of rock immediately below
gage shelter; at high stages a gravel bar forms part of the control. Stage dis-
charge relation permanent at low stages; likely to shift somewhat at flood stages.
Extremes of discharge. — 1908-1917: Maximum stage recorded, 11+ feet June 5,
1908 (discharge not determined); stage of 7.80 feet recorded June 22, 1916 (dis-
charge, 8,620 second-feet); minimum stage, 5.42 feet February 5, 1914 (discharge,
70 second-feet). (See hydrograph, PI. IV.)
Ice. — Stage-discharge relation affected by ice during winter.
Diversions. — Water is diverted by the United States Reclamation Ser\'ice at a point
near Babb, Mont., from St. Mary River to the North Branch of Milk River for the
irrigation of lands in the lower Milk River valley and by the Alberta Railway- &
Irrigation Co. at Kimball, 1^ miles below the station.
Regulation. — The United States Reclamation Service has under construction a largo
reservoir on the headwaters of Smftcurrent Creek, but as no water has yet been
stored the stream-flow records have not been affected.
Accuracy. — Stream bed and control shifted slowly butsleadil\- at site used from 1908
to 1912 and also at site of automatic gago and cable installed in 1913 for use of tlio
M WATER SUPPLY OF ST. MARY AND MILK RIVERS, 1898-1917.
United States and Canada. Stage-discharge relation at new site selected for gage
and cables in 1916 permanent at low stages in 1917 but slightly shifting at higher
stages. Rating curves well defined between 220 and 4,840 second-feet. Open-
water discharge determined by applying mean daily gage height to rating tables;
winter discharge determined from hydrograph prepared from discharge measure-
ments and by comparison of maximum and minimum temperatures and gage-
height graphs.
Records good.

Note.— Table summarizes stream-flow data for St. Mary River where it crosses international boundary
prepared from records obtained by the United States at gaging station formerly maintained near the
boundary, from records obtained by the Canadian Government at gaging station formerly maintained near
Kimball, Alta. , and from recent records obtained at the station jointly maintained near Kimball by repre-
sentatives of the two Governments.
During the year 1917 water was diverted from St. Mary River at a point about half a mile below the
outlet of Lower St. Mary Lake by the United States Reclamation Service St. Mary canal. This water,
less the quantity lost by seepage, was delivered to the North Fork of Milk River. A large proportion of the
seepage waters returned to St. Mary River, either above the station near the international boundary or
by way of Rolph (Willow) Creek at a point between that station and the one near Lethbridge. The' fol-
lowing table shows the water diverted from the St. Mary River drainage by the United States Reclama-
tion Service St. Mary canal, exclusive of seepage losses from the canal:

ST. MARY RIVER NEAR LETHBRIDGE, ALTA.i
Location, — In the NE. | sec. 26, T. 7, R. 22 W. fourth meridian, 8 miles southwest
of the city of Lethbridge and 4 miles above confluence with Oldman River.
Drainage area. — 1,394 square miles.
Records available. — October 13, 1911, to December 31, 1917.
Gage. — Stevens continuous water-stage recorder installed June 8, 1916; prior to that
date a vertical staff graduated to hundredths of a foot; winter readings still
obtained from the vertical staff. Staff gage read by W. D. Whitney.
Discharge measurements. — Made from cable 1,680 feet downstream from gage.
Channel and control. — Bed composed of coarse gravel. Right bank low and sub-
ject to overflow at flood stages; left bank high and not subject to overflow.
Control is a large gravel bar and is likely to shift during floods.
Extremes of discharge. — 1911-1917: Maximum stage recorded, 3.91 feet June 22,
1916 (discharge, 8,964 second-feet); minimum stage recorded, 0.15 foot, October
_ 5, 1913 (discharge, 46 second-feet). (See hydrograph, PI. V.)
Ice. — Stage-discharge relation affected by ice during winter season.
Diversions. — The United States Reclamation Service and the Alberta Railway &
Irrigation Co. divert water from the river for irrigation above this station.
Accuracy.^ — Stage-discharge relation permanent during open-water periods 1916 and
1917; fairly permanent 1911 to 1914; control shifted in 1915. Staff gage read
daily to hundredths 1911 to June 7, 1916, and during winter periods. Operation
of water-stage recorder not completely satisfactory throughout op en- water season
of 1917, as shown by breaks in record. Daily discharge for open- water periods
obtained by appljdng mean daily gage height to rating table; discharge for periods
in which record was broken obtained by comparison with records obtained from
stations on St. Mary River near international boundary; winter discharge ascer-
tained from hydrograph based on daily gage heights, discharge measurements,
and records of temperature. Records fair.

72 WATER SUPPLY OF ST. MARY AiTD MILK RIVERS^ 189-8-1917.
STATIONS ON TRIBUTARIES.
SWIFTCTJRRENT CREES: AT MANY GLACIER, MONT.
Location. — In sec. 12, T. 35 N., R. 16 W., at outlet of McDermott Lake, at Many
Glacier, in Glacier National Park, about 14 miles southwest of Babb, in Teton
County. (See PL VI, A.)
Drainage area. — 31.4 square miles (measured on Glacier National Park topo-
graphic map).
Records available. — ^June 6, 1912, to December 31, 1917.
Gage. — Vertical staff on shore of lake about 75 feet from right end of outlet; prior to
May 22, 1916, a staff gage on lake shore near left end of outlet.
Discharge measurements. — Made by wading at outlet of lake or below the falls;
high- water measurements made from highway bridge above power house ; section
at bridge is very poor. From 1912 to 1914 high-water measurements were made
from a cable at outlet of lake.
Channel and control. — Limestone outcrop at outlet of lake; just below the control
is a cataract. (See PI. VI, A.) Movement of a few small boulders scattered over
the control is the only cause of change in rating curve.
Extremes of discharge. — Maximum stage recorded, 4.75 feet June 17, 1916 (dis-
charge, 1,530 second-feet); minimum discharge recorded, 8.7 second-feet April 1,
1913, by current meter measurement. The gage read 1.30 feet, but the stage-
discharge relation was affected by ice.
IcE. — Stage-discharge relation very little affected by ice.
Diversions. — None.
Regulation. — None.
Accuracy. — Stage-discharge relation permanent except during an occasional period
of high water when gravel and small boulders may lodge on control. Daily
discharge ascertained by applying mean daily gage height to rating table.
Records considered good.

Note. — Average not computed if the monthly mean was not available for five years of more. Means
for periods of 16 days or over assumed mean for the month. Means for less than 16 days not included when
computing average and median values. The totals in acre-feet were not averaged' because the records
covered different periods in different years. The medians given were obtained by arranging the monthly
means in their order of magnitude arid taking the middle mean, or, if the number was even, the average
Of the two middle means. By using daily discharge a somewhat lower median discharge would be
obtained.
WATER SUPPLY OF ST. MARY AND MILK RIVERS;, 1898-1917. 77
SWIFTCURRENT CREEK BELOW SHERBURNE LAKE DAM, MONT.,
Location. — In sec. 35, T. 36 N., R. 15 W., near outlet of Lower Sherburne Lake, in
Teton County. (See PL VI, B.)
Drainage area. — 64 square miles (measured on topographic map of Glacier National
Park.) . •
Records available. — July 1, 1912, to December 31, 1917.
Gage. — Staff gage on left bank about 300 feet below the spillway of Sherburne Lake
dam; read by employees of the United States Reclamation Service. From July 1
1912, to November 9, 1914, a vertical staff gage was maintained on the left bank
near the outlet of the lake, and at a datum different from that of the present gage.
Discharge measurements. — Made by wading or from cable 50 feet below gage.
Channel and control. — An outcropping limestone ledge, somewhat broken and
irregular, forms the control, and is subject to small changes. A landslide caused
by the building of the dam has forced out the left bank a foot or so into the river
channel.
Extremes op discharge. — Maximum stage recorded, 7.85 feet June 17, 1916 (dis-
charge, 2,280 second-feet); minimum stage, no flow December 22-28, 1917, owing
to storage in reservoir above.
Ice. — Stage-discharge relation not seriously affected by ice.
Diversions. — None.
Regulation. — The natural flow of the stream was affected from 1915-1917, by placing
and removing flashboards on the temporary dam built at the outlet of the lake in
connection with the construction of the Sherburne Lake storage dam.
Accuracy. — Stage-discharge relation not permanent, owing to small movements of
the gravel at the control during high water. A landslide, first noticed in 1917, has
changed the control. Discharge measurements indicate the time and amount of
the effect on the rating curve. Flow partly regulated by operation of gates.
Records good.

Note. — Average not computed if the monthly mean was not available for 5 years or more. The totals
in acre-feet were not averaged because the records covered different periods in different years . The median
flow given was obtained by arranging the monthly means in their order of magnitude and taking the middle
mean, or, if their number was even, the average of the two middle means. By using daily discharge a
somewhat lower median discharge v/ould be obtained.

Location. — In sec. 34, T. 37 N., R. 14 W., 50 feet above the road from Babb, Mont.;
to Cardston, Alta., Canada, and about 2 miles north of Babb.
Drainage area.— 50 square miles (measured on topographic maps).
Records available. — Some discharge measurements in 1903-1912, and monthly
estimates based on discharge measurements and scattered gage readings for June,
July, August, and September, 1905.
Discharge measurements. — Made from cable.
Channel and control. — Bed composed of boulders; would shift only during floods.
Diversions. — None.
Regulation. — None.
Accuracy. — Estimates of mean discharge for June, July, August, and September,
1905, given in a footnote to the table of daily gage heights, are based on a few
scattered gage-height observations and several discharge measurements. As this
stream is fed by melting snow its flow is fairly constant and the estimates are fair.

ROLPH CREEK NEAR KIMBALL, ALTA.
Location.— In SE. \ sec. 21, T. 2, R. 24 W. fourth meridian.
Drainage area. — 74 square miles.
Records available. — May 17, 1911, to October 31, 1916. Gage-height observa-
tions April 4 to July 31, 1917.
Gage. — Vertical staff; read by J. M,. Dunn.
Channel. — Sand, gravel, and stone. Control likely to shift.
Discharge measurements. — Made by wading.
Ice. — Observations discontinued during winter months.
Accuracy. — Stage-discharge relation not permanent. Gage ^ead to hundredths
daily. Daily discharge obtained by applying daily gage height to rating table.
Records poor. As the only discharge measurement made in 1917 shows that the
cross section was very much eniatged in the spring of 1917, daily discharge for
that year could not be computed.

Right bank subject to overflow; left bank high and not subject to overflow.
Extremes or discharge. — 1913-1917: Maximum stage recorded. 4.10 feet June 29,
1916 (discharge, 913 second-feet); minimum stage recorded, 3.10 feet February
21, 1914 (discharge, 5.2 second-feet).

120 WATEE SUPPLY OF ST. MARY AND MILK RIVERS, 1898-1917.
POTHOLE CREEK NEAR MAGRATH (LOWER STATION), ALTA.
Location. — In NE. J sec. 1, T. 6, R. 22 W. fourth meridian, 3 miles northeast of Ma-
grath, 4 miles below spillway of the Alberta Railway & Irrigation Go's, canal.
Drainage area. — Not computed, as part of the flow past this station is waste water
from the Alberta Railway & Irrigation Co.'s canal.
Records available. — April 28, 1914, to October 31, 1917.
Gage. — Chain gage on left bank, read by John Brown.
Discharge measurements. — Made by wading or from cable.
Channel and control. — Bed, composed of sand; constantly shifting. Banks low
and subject to overflow. Control likely to shift.
Extremes of discharge. — 1914-1917. Maximum stage recorded, 4.50 feet June 28,
1916 (discharge, 1,300 second-feet); minimum stage recorded, zero, October
10 to 14 and 22 to 31, 1914.
Ice. — Observations discontinued during winter season.
Accuracy. — Stage-discharge relation not permanent. Owing to unstable nature of
control and stream bed rating curves are very poorly defined. Gage read daily to
hundredths. Daily discharge obtained by applying daily gage heights to rating
tables and applying corrections for periods of shifting control. Record poor.

FIDLER BROTHERS' DITCH AT BOTJNDARY CREEK, ALTA.
Location. — In the SE. ^ sec. 19, T. 1, R. 26 W. fourth meridian, at Boundary Creek
post office, 15 miles southwest of Cardston, Alta.
Records available. — September 13, 1911 to July 13, 1914, and July 10 to 17, 1917.
Gage. — Vertical staff driven in bed of ditch; read by James Fidler.
Discharge measurements. — Made near gage.
Channel and control. — Permanent.
Water diverted from July 10 to July 17, 1917. As no measurements were obtained
it is impossible to systematize daily discharges. From the mean gage height, slope, and
cross-section flow is estimated as 0.77 second-foot, or 12 acre-feet for period.

ALBERTA RAILWAY «fe IRRIGATION CO.'S CANAL AT KIMBALL, ALTA.
Location.— In SE. \ sec. 30, T. 1 , R. 25 W. fourth meridian, at the village of Kimball,
12 miles from railway station at Cardston, 200 yards below Alberta Railway &
Irrigation Co.'s dam on St. Mary River, Station replaces one in the SE. \ sec.
21, T. 2, R. 24 W. fourth meridian, on the flume G miles down the canal from the
head gates. (See PL VIII.)
Records available, — During irrigation seasons, May 1, 1910, to October 21, 1917,
Gage. — Inclined staff set in concrete lining of canal at control, (hige road daily
by W. D. Willgrass to August 1 ; from that date by William Nicolls.
Discharge measurements. — Made from suspension bridge.
Channel and control. — Bed and control composed of loose gravel, which is likely
to shirt. High gravel banks, lined with concrete for few feet at section.
126 WATER SUPPLY OF ST. MARY Al^lJ MILK RI^^RS, 1898-1917.
Extremes of discharge. — 1910-1917: Maximum stage recorded, 53 inches at flume
No. 1 June 20, 1910 (discharge, 858 second-feet); minimum stage recorded, 0.55
foot October 17, 1911 (discharge, 18 second-feet).
Regulation. — Discharge controlled by head gates 500 feet above station.
Accuracy. — Stage-discharge relation practically permanent at the concrete measuring
section at present in use or at the former station at the flume. Slight change in
control at present station probably due to shift of gravel below measuring station.
Gage readings apparently too few for close determination of mean daily discharge.
Records fair.

134 WATEB SUPPLY OF ST. MAPvY AND MILK KIVERS, 18&8-1917.
ALBERTA RAILWAY & IRRIGATION. CO.'S CANAL AT SPRING COITLEE, ALTA.
Location. — In the NW. i sec. 28, T. 4, R. 23 W., fourth meridian, at Spring Coulee,
about half a mile east of the railway station. (See PI. IX.)
Records available. — Irrigation seasons May 1, 1914, to October 19, 1917.
Gage. — ^Vertical staff set in bed of canal near left bank; read by F. H. Kelley.
Discharge measurements. — Made from a cable 150 feet above gage.
Channel and control. — Bed composed of sand, clay, and small stones. High clay
banks; not subject to overflow, but likely to cave in and change control during
and after high stages.
Extremes of discharge. — 1914r-1917: Maximum stage recorded, 4.75 feet, July 1,
1914 (discharge, 638 second-feet); minimum stage recorded, 2.09 feet, July 4, 6,
and 7, 1916 (discharge, 36 second-feet).
Regulation. — Flow controlled by head gates at Kimball and by waste gates, by
which water can be emptied into Pinepound creek, about a mile above gage at
Spring Coulee.
Accuracy. — Stage-discharge relation not permanent; affected by shifting of bed and
caving banks. Gage read to hundredths daily. A few inaccuracies in observa-
tions appear to have occurred during 1917. Daily discharge determined by apply-
ing daily gage heights to rating table, and by shifting-control method. Records
fair.

MILK RIVER DRAINAGE BASIN.
GENERAL FEATURES.
Milk River heads from springs scattered through the rolHng foot-
hills on the east side of the St. Mary lakes and river. This tract of
hilly country is shown on the United States Government maps as
St. Mary E,idge and forms part of the divide between waters flowing
to Hudson Bay and those flowing to the Gulf of Mexico through the
Missouri and Mississippi. (See PL I.)
The catchment area of Milk River is very large, extending through
about 2 degrees of latitude, but as its basin is for the most part cut
off from mountainous areas the river does not receive a constant sup-
ply of water from permanent bodies of snow and ice and its volume
is subject to sudden fluctuations due largely to precipitation.
The river is formed by three principal branches — the South, Mid-
dle, and North forks. South Fork, considered the continuation of
the main stream, is joined by the Middle Fork and flows north-
easterly, crossing the international boundary in range 20. The North
Fork, w^hich also flows northeasterly, crosses the international bound-
ary in R. 23 W., fourth meridian, very nearly in longitude 113° W.,
19 miles w^est of the crossing of the South Fork. -In Canada the
WATER SUPPLY OF ST. MARY AND MILK RIVERS, 1898-1917. 141
North Fork continues its northeasterly direction to a point nearly 14
miles due north of the boundary, where it turns sharply south and
joins the South Fork hear the middle of T. 2, E, 18. From the junc-
tion of these forks the river flows easterly on a course generally paral-
lel to the international boundary, which it finally crosses close to the
east boundary of E. 5 W., fourth meridian, 90 miles east of the cross-
ing of the South Fork. At no place is the main stream more than
11 miles north of the international boundary, and the average dis-
tance is about 7 miles.
From its final crossing, in E. 5, the river flows southeastward to
Havre, Mont., a point near the junction of the main line and Great
Falls branch of the Great Northern Eailway. Thence the general
direction is easterly, bearing gradually to the south. The distance
from the final crossing of the boundary to the junction of the Milk
with the Missouri is, by general course, about 245 miles, and the dis-
tance of that junction due south of the international boundary is
very nearly 70 miles. The length of the stream flowing in Canada
from the North Fork crossing to the final crossing is, following the
sinuosities, 216 miles, and from the South Fork crossing about 177
miles.
Along the North and South forks there are no flats of magnitude
and the banks are in .most places comparatively low but steep and
the valleys narrow.
From the junction of the main branches to Pendant d' Oreille, in
sec. 21, T. 2, E. 8, the river valley is as a rule narrow and treeless
and slopes are comparatively gentle; but below Pendant d'Oreille,
as far down as the mouth of Lost Eiver, the banks are very high and
steep and the area back of the river is composed principally of bad
lands. The valley itself is narrow, wooded, and deeply cut by freshet
channels from the clay and sandstone formation above. The bed of
the river along this stretch is quicksand and shifts greatly at high
stages.
From the mouth of Lost Eiver to Havre the river banks and bed
resemble those of the stretch last mentioned, though the bad lands
arc less pronounced and the banks are lower and less steep. The
valley is somewhat wider, but the land is very poor, the vegetation
scant, and forests are lacking.
Below Havre, however, the hills are lower, the slopes are gentle,
and the vaUcy itself, which here ranges in width from a mile to 4
miles, contains some first-class agricultural land which, under irriga-
tion, gives very good growths of alfalfa, garden stuff, and cereals;
and from Havre to the mouth of the river there is a consick^rablo
growth of trees, such as large poplars and wiUows.
The river bed remains unchanged and is composed of (luicksand
with occasional gravelly rapids. The fall is small, the current is
142 WATER SUPPLY OF ST. MARY AND MILK RIVERS, 1898-1917.
sluggish at low water, and in most places the banks are likelj^ to be
overflowed in flood water.
The area between Chinook and Malta, where the average width of
the valley is about 3 miles, is in general composed of very flat land,
and the soil ranges from sandy loam to ''gumbo," which under irriga-
tion yields good crops. From Malta around the big bend to a point
northeast of Saco the valley is again narrow, and though wider than
that above Havre, resembles that stretch of stream in some respects.
Below this point the valley widens out and some very fine flats border
the river on each side clear to its mouth.
Mlk Kiver in Montana is fed by numerous tributaries from both
north and south between Havre and the mouth, those on the north
rising between the Cypress Hills, Old-Man-on-his-Back Plateau,
Boundar}^ Plateau, and Wood Mountain, and those from the south
rising in the Sweetgrass Hills, Bear Paws, and Little Rocky Moun-
tains. In its course through Canada the stream receives a few small
and unimportant tributaries that rise in the Sweetgrass Hills, but
practically all the area immediately north of the river is drained into
Pakowki Lake.
The area drained by Milk River might be expected to present a
great variety of topographic conditions and in a sense it does, for the
range in elevation is between about 1,900 and 7,000 feet above sea
level. The greater part of this whole area, however, might be ap-
propriately described as roUing prairie and foothill country. The
outstanding topographic limits of the basin are the foothills of the
Rocky Mountains in the Blackfeet Reserve, the Milk River Ridge,
which extends northeastward from them into Canada, the Cypress
Hills and Wood Mountain on the north, and the Sweetgrass Hills,
the Bear Paw, and Little Rocky Mountains on the south. Between
these limits can be found almost all varieties of prairie country,
from level plains to steep, broken, clay cliffs, bare of vegetation; but
as a whole the area is extremelv roUinsr and is broken bv numerous

channels that carry much water during the freshet season but are
dry for 10 or 11 months a year. Springs are numerous but small and
have little effect on the flow in the main drainage channels.
Two remarkable depressions occur in what might otherwise be con-
sidered a part of the catchment area of Milk River — one in Tps. 3, 4,
5, and 6, Rs. 4 to 21 W. fourth meridian, and the other in the large
tract east of Battle Creek and south of Frenchman River. The first
depression, forming the drainage basin of Pakowki Lake, is at its
lowest point 27 feet lower than the bed of Milk River to the south;
the second, lying between the banks of Frenchman River on the north
and east and the Boundary and Old-Man-on-liis-Back plateaus on
the south and west, is a large shallow basin full of small lakes and
sloughs that have no outlets to the adjacent stream channels.

GAGING- STATION RECORDS.
STATIONS ON MAIN STREAM.
SOUTH FORK OF MILK RIVER NEAR IKTERNATIONAL BOTINDARY.
LocATiox. — In SW. I sec. 29, T. 37 N., R. 9 W., at Richard Croff' s ranch, just above
Kennedy Coulee, in Teton County, about 30 miles northeast of Brooming, and 5
miles south of the international boundary.
Drainage area. — 288 square miles (measured on topographic map).
Records available. — April 28, 1905, to December 31, 1917.
Gage. — Stevens continuous water-stage recorder on the left bank, above the mouth
of Kennedy Coulee and about 500 feet from Richard Croff 's ranch house; prior
to October 13, 1917, the station was on left bank, 400 feet farther upstream. April
28 to May 8, 1905, a staff gsige was read ; May 8, 1905, to April 13, 1913, overhanging
chain gage. April 13, 1913, to December 31, 1917, Stevens continuous water-
stage recorder supplemented by readings by the observer on an overhanging
chain gage.
Discharge measurements. — Made from cable 300 feet above gage or by wading.
Channel and control. — Bed composed of clay and small boulders. Growth of
aquatic plants affects stage-discharge relation at low stages during summer.
Banks high and not subject to overflow except during extreme floods.
Extremes of discharge. — ^^Vlaximum stage recorded, 15.4 feet June 6, 1908, deter-
mined from high -water marks; flood width, 850 feet; flood cross-section, about
2,600 square feet ; minijnum stage recorded, 2.9 feet August 18-20, 1906 (discharge,
1 second -foot).
Ice. — Ice period extends from November to April. During mild winters the stage-
discharge relation may be affected by ice for short periods only. Records for
such periods are based on discharge measurements, temj>erature records, observer's
notes, and hydrographic comparison with flow of other streams.
Diversions.— None.
Regulatio.v. — None.
Accuracy. — Stage-discharge relation affected by ice and by shifting control; changes
covered by numerous discharge measurements. Gage-height records good since
installation of water-stage recorder. Records beginning with 1913 are good;
those previous to that year are fair.
Cooperation. — Beginning with 1913 station maintained under a cooperative agree-
ment between the Reclamation Service, Department of the Interior, Canada, the
United States Reclamation Service, and the United States Geological Survey.

Note. — Means for periods less than a full month but exceeding 15 days were considered means for the
month in finding average and median flow. Averages were not computed for January and February, as
the period of record was considered too short. The totals in acre-feet were not averaged because the rec-
ords covered different periods in different 5^ears.
Figures showing maximum and minimum are for full months. The median flow was obtained by ar-
ranging the monthly means in then* order of magnitude and taking the middle mean, or, if their number
was even, the average of the two middle means. By using daily discharge a somewhat lower median
discharge would be obtained.

Channel and control. — Bed of stream composed of quicksand and gravel; clean
and shifting. Right bank high, clean, and subject to overflow at extremely
high water only: left bank low. Two channels at very low water. Control not
permanent.
Extremes of discharge. — 1909-1917: Maximum stage recorded, 8.50 feet Feb-
ruary 17, 1916 (discharge, 3,467 second-feet); minimum stage, 1.75 feet February
9, 1914 (discharge, 1.0 second-foot). (See hydrograph, PL XI.)
Ice. — Stage-discharge relation affected by ice during winter season.
Regulation. — Flow at this station was affected in 1917 by diversion of water from
St, Mary River to Milk River by the United States Reclamation Service.
Accuracy. — Stage-discharge relation not permanent. Gage read to hundredths
daily. Daily discharge for open-water periods obtained by applying daily gage
height to rating table; winter discharge ascertained from hydrograph based on
daily gage heights, discharge measurements, and records of temperature. Records
fair.

MILK RIVER AT EASTERN CROSSING OF INTERNATIONAL BOUNDARY, MONTANA.
Location. — In NE. I sec .6, T. 37 N., R. 9 E. Montana principal meridian, at inter-
national boundary, 30 miles north of Rudyard, Hill County, Mont., and 37 milea
south of Manyberries, AJta., the nearest railway stations. (See PL X, B.)
Drainage area. — 2,514 square miles (measured by engineers, Reclamation Service,
Department of the Interior, Canada).
Records available. — April 1, 1913, to December 31, 1917. From August 7, 1909,
to April 1, 1913, station was maintained 1,000 feet upstream by Reclamation
Service, Department of the Interior, Canada.
Gage. — Gurley printing gage installed September 18, 1917, on right (south) bank, and
referred to two staff gages, one inside in well, and one outside in trench. The
station maintained by Canada from August 7, 1909, to April, 1913, was equipped
with a staff gage and cable and was 1,000 feet upstream. Kennedy Coulee, a small
dry coulee, is tributary between the two locations. This was made a joint inter-
national station on April 1, 1913, when a staff gage was installed on the left (north)
bank 200 feet below the present gage. This gage was used until August 13, 1913.
Gages previously used as follows: April 1 to August 13, 1913, staff gage on left (north)
bank, 200 feet below present gage; August 13, 1913, to March 22, 1917, Gurley print-
ing gage referred to staff gage in river 10 feet below gage house; April 9 to June 13,
1917, several temporary gages were used, but all readings have been referred to the
staff gage at the site of the one used August 13, 1913, to March 22, 1917; June 14 to
September 18, 1917, readings on a staff gage at present site. Zero of gage on north
bank was 2,696.58 feet sea level; that of present gage on south bank is 2,698.92
feet sea level. Staff gages read and automatic gages attended to by Frank Galloway.
Discharge measurements. — Made from cable or by wading 100 feet below cable.
Channel and control. — A bar composed of heavy boulders, gravel, and sand makes
a decided riffle at medium and low stages, and shifts frequently.
Extremes of discharge. — Maximum stage recorded, 9.60 feet April 9, 1917 (dis-
charge, 4,860 second-feet); channel reported dry August 3-17, 22, 23, 1914. (See
hydrograph, PI. XII.)
Ice. — Stage-discharge relation seriously affected by ice during winter months. Short
periods of open channel conditions may occur during floods.
Diversions. — A few small diversions on the headwaters and tributaries.
Regulation. — T^ow-water flow materially increased by water from ITuited States
Reclamation Service St. Mary canal during July, August, and Septomhor, 1917.
Accuracy. — Stage-discharge relation not permanent. Frecjuont ditscharge measure-
ments indicate shifts. Cfage height-recx^rd is good. Discharge records good.

WATER SUPPLY OF ST. MARY AITD MILK RIVERS, 1898-1917. 193
MILK RIVER AT HAVRE, MONT.
Location.— In SW. i SW. i sec. 4, T. 32 N., R. 16 E., at highway bridge over Milk
River at Ha\Te, in Hill County.
Drainage area. — Not measured.
Records available. — May 15, 1898, to December 31, 1917.
Gage. — Chain gage fastened to doAvnstream rail of bridge. Owing to the foiTaation
of sand bars in the river, it has often been necessary to move gage from one end of
the bridge to the other, but the datum has not been changed.
Discharge measurements. — Made from highway bridge or by wading.
Channel and control. — Bed of stream composed of fine gravel and sand, shifting
frequently. Both banks are overflowed at high stages.
Extremes of discharge. — Maximum stage recorded, 17.2 feet March 12, 1916 (dis-
charge not known); minimum stage recorded, channel reported dry July 16-18,
1898; August 16-20, 1904; July 25, August 18-26, 1905; November 16 to December
31, 1906; July 28 to September 14, 1910; July 29 to August 22, 1914. (See hydro-
graphs, Pis. XIII-XIV.)
Ice. — During the winter months the stream is completely frozen and the discharge is
too small to determine except by discharge measurements. Periods of warm
weather may cause sudden floods due to melting snow. At such times the open
channel rating curve is applicable, except when an ice gorge forms below the
gage.
Diversions. — ^A few small diversions on the headwaters and tributaries.
Regulation. — During 1917 the St. Mary canal was in operation, and a total of 33,600
acre-feet was added to Mlk River flow.
Accuracy. — The United States Weather Bureau also maintained a station at this
point and the gage is read by their observer or one of his sons. Frequent changes
in the sand bars forming the control render a large number of discharge measure-
ments necessary each year to insure good results. If one or two measurements
are made each month the records are good; if fewer measurements are made the
records are fair to poor.

Note.— 1898: Discharge estimated as follows: Nov. 20-30, 100 second-feet; Dec. 1-4, 113 second-feet.
1899: Records originally published for January omitted from compilation because based on insufficient
data. Only scattering gage heights reported June 1 to Aug. 31 and Nov. 6-30.
1900: Nov. 16 to Dec. 16and Dec. 23-31, river frozen; gage heights not reported.
1901 : Mar. 11-31, stage-discharge relation assumed unaffected by ice; as originalljr published the mean foi
this period was estimated at 600 second-feet; mean flow Mar. 1-10 was probably twice as great as from Mar.
11-31, but stage-discharge relation was affected by ice gorge and accurate estimates can not be made. Nov.
7 and Nov. 22-30, stage-discharge relation aflected by ice; mean discharge estimated at 80 second-feet.
WATER SUPPLY OF ST. MARY A]!i5'D MILK RIVERS, 1898-1917. 207
1902: Records originally published for January, November, and December omitted from compilation
because based on insufficient data. Open-channel rating curve assumed applicable Feb. 19 to Nov. 1, 1902.
1903: Records Jan. 1 to Mar. 31 and Nov. 13 to Dec. 31 omitted from compilation; base data inadequate.
Discharge Apr. 1-4, 1903, estimated.
1904: Records Jan. 1 to Mar. 31 and Dec. 1-31 omitted from compilation; base data inadequate.
1905: Records for January and Febiniary omitted from compilation; base data inadequate. Daily dis-
charge Mar. 1-31 determined by applying open-channel rating curve to gage heights; results obtained in
this way are consistent with those obtained at Malta. Channel dry Aug. 15 to Dec. 31.
1906: Practically no flow Nov. 16 to Dec. 31.
1907: Records for February and December omitted from compilation; base data inadequate. Stage-
discharge relation affected by ice Mar. 1-20; discharge estimated at 400 second-feet.
1908: Stage-discharge relation affected by ice Mar. 1-15, Nov. 13-16, and Nov. 25-30; discharge estimated.
Gage heights not reported Mar. 27 to Apr. 2; discharge estimated.
1910: Records for January, February, and December omitted from compilation; base data inadequate.
Mar. 1, discharge estimated. Channel di'y July 28 to Sept. 14.
1911: Records for December omitted from compilation; base data inadequate. Mar. 1-8 and 14-17,
discharge estimated. Nov. 8-30, mean discharge estimated at 75 second-feet.
1913: Accuracy of gage-height observations for September and of the determinations of discharge based
thereon are questionable.
1914: Channel dry July 29 to Aug. 22.
1915: Shifting-control method used to determine daily discharge from May to November 11. Discharge
measurements were made frequently, but the results are 10 to 20 per cent lower than they should be to
make them consistent with those obtained at stations above. Gage not read; discharge interpolated Nov
12-21. Discharge Nov. 23-30 estimated at 50 second-feet.
1916: Chinook winds and ice jams in February and March caused the river to rise rapidly, a stage of 15.9
feet being reached Feb. 21-22 and 17.2 feet Mar. 12, Flow not computed Nov. 11 to Dec. 31. Gage read
alx)ut three times a week. Shifting-control method used to determine daily discharge Apr. 24 to May 3
and May 26 to July 3.
1917: Jan. 1 to Mar. 27, gage read about three times a week; flow not computed. Gage not read July 1-12,
discharge estimated at 370 second-feet by comparison with record of flow of Milk River at eastern crossing.

Note.— 1898: Mean discharge for December, originally published, has been discarded because it was
obtained by applying open-channel rating curve. The minimum temperature in this locality in November
was —14°, and in December it was —15°. This temperature would cause considerable ice to form in the
river at the gage.
1899: Monthly means for May, June, July, August, and November, recomputed by interpolating between
gage readings. Published records did not give weight to the time between readings. See footnote to daily
discharge for published monthly means omitted based because on insufficient data.
1901: Meanm,onthly discharge for November estimated from daily discharge Nov. 1-21.

t Estimated natural flow.
Note. — Means for periods less than a full month but exceeding 15 days were considered means for the
month in finding average and median flow. The median flow given was obtained by arranging the
monthly means in their order of magnitude and taking the middle mean; or, if the number was even, the
average of the two middle means. By using daily discharge a considerably lower median discharge would
be obtained. The total yearly flow in acre-feet has been averaged because in general the period of record
covers the open-water season and the flow during months for which records are missing was usually small.
Mean flow for July. August, and September, 1917, obtained by subtracting the water diverted to Milk
River by United States Reclamation SerAJ^ice St. Mary canal, A loss of 25 per cent was assumed between
the outlet of the canal and Havre, and 8 days was assumed as the period of transit between the two points.
MILK RIVER AT CHINOOK, MONT.
Location, — In sec. 34, T. 33 N., R. 19 E., at the wagon bridge over Milk River 1
mile south of Chinook, Mont.
Drainage area. — Not measured.

25 to October 23, 1897,
DiscHAGE measurements, — Made from highway bridge or by wading.
Channel and control, — Bed is composed of sand; shifts frequently.
Extremes of stage. — Maximum stage recorded, 8.95 feet June 17, 1897; minimum
stage recorded 0.5 foot August 27, 1897,
Ice, — Ice not present during the period of record.
Diversions, — Fort Belknap canal, the capacity of which is about 100 second-feet,
diverts water from Milk River above tliis station.
Regulation. — None,

Note. — Station was moved to Havre, Mont., in 1898.
MILK RIVER AT MALTA, MONT.
Location.— In NW. ^ sec. 17, T. 30 N, R. 30 E., at old highway bridge at Malta,
in Phillips County.
Drainage area. — Not measured.
Records available. — July 31, 1902, to December 31, 1917. ,
Gage. — Chain fastened to guard rail on downstream side of bridge; read by employees
of the United States Reclamation Service. The gage has been moved several
times to different points on bridge, but datum was not changed.
Discharge measurements. — Made from bridge or by wading,
Channel and control. — Bed of stream composed of gravel; permanent except for
slight shifts at low stages. Partial control at gage at low water, but the principal
control is formed by a bar or ridge that produces a riffle half a mile below the gage.
Extremes of discharge. — Maximum stage recorded, 19.75 feet April 10, 1917
(discharge, 11,200 second-feet); minimum stage recorded, channel reported dry
August 13 to November 10, 1904; April 24 to May 8, and August 30 to end of
year, 1905; April 10, 27-29, May 1, 4-23, 1906; July 16 to December 8, 1910. (See
hydrographs. Pie. XVI-XVII.)
Ice. — Stage-discharge relation is affected by ice during winter months. Generally
the flow is low from December to the spring break-up, which comes in March
or April. Warm periods during the winter may cause sudden rises. When this
happens, the open channel rating curve can be applied except when there are
ice jams below.
Diversions. — Entire run-off from drainage basin above does not pass the station,
for a large number of irrigation canals divert water from Milk River and its tribu-
taries between Havre and Malta. The United States Reclamation Service has
constructed a diversion dam (PI. XV) at Dodson, about 17 miles above the
station. The Dodson South canal, heading at this point, has a capacity of 900
second-feet, and the Dodson North canal a capacity of 200 second-feet.

Regulation. — Part of flood flow is diverted into Nelson reservoir and held for use
in irrigation.
Accuracy. — Stage-discharge relation permanent except for slight shifts of control
at low stages and during winter season. Gage read twice daily to hundredths.
Open-water records excellent; winter records considered fair.

226 WATER SUPPLY OF ST. MAEY AND MILK RIVERS^ 1898-1917.
MILE RIVER AT HINSDALE, MONT.
Location.— In the NE, i SW. i sec. 33, T. 31 N., R. 36 E., at highway bridge over
Milk River about a mile from Hinsdale, a point 46 miles above junction of Milk
River with the Missouri.
Drainage area.. — Not.measured.
Records available. — May 13, 1908, to November 13, 1914. On account of back-
water the station was moved to Vandalia dam, about 8 miles downstream, in
1915, the flow at this point being practically the same as at Hinsdale.
Gage. — Chain fastened to upstream side of highway bridge.
Channel and control. — Bed of stream is gravel with a deposit of mud along the
banks. Banks are high and are overflowed only during extreme floods. Water
at the gage is deep and sluggish at low stages, due to a gravel bar 1 mile below,
which forms the control.
Discharge measurements. — Made from bridge or by wading.
Extremes of discharge. — 1908-1914: Maximum stage recorded, April 6, 1912,
discharge estimated at 24,200 second-feet; river reported dry August 9-13, 1910.
(See hydrograph, PI. XVIII.)
Ice. — Stream usually frozen entirely across and to a considerable depth from late
iin November until the first of April,
Diversions. — No water is diverted between station at Malta and that at Hinsdale.
Above Malta numerous canals divert water from the main stream and nearly all
the tributaries.
I
Regulation. — Some return water from irrigation increases the low-water flow during
summer months. •
Accuracy. — Stage-discharge relation permanent except during floods. Records good. \

Note. — 1908: Sept. 1 to Nov. 18, daily discharge as originally published believed to be in error due to
errors in gage readings; as it is impossible to determine the correction to gage readings for this period, the
record has been omitted from the compilation.
1910: Nov, 13-30, mean discharge estimated 2.5 second-feet.
1911: Mar. 1-20, mean discharge estimated 300 second-feet.
1912: daily discharge Apr. 5-17, estimated from the high-water mark which was referred to gage datum
by leveling; also from a current meter measurement at Vandalia, 6 miles below Hinsdale, on Apr. 10,
the date of the highest water having been observed by the hydrographer. Aug. 9-12, 14-20, and 22-29, dis-
charge estimated. Mean discharge Nov. 17-30, estimated at 250 second-feet.
1913: July 10-19, discharge estimated at 380 second-feet.
1914: Apr. 1-3, discharge estimated at 1,100 second-feet; May 30 to Jime 6, discharge interpolated.

MILK RIVER NEAR VANDALIA, MONT.
Location. — In sec. 7, T. 30 N., R. 37 E., at Vandalia dam of United States Reclama-
tion Service, 2 miles west of Vandalia in Valley County. (See PI. XIX.)
Drainage area. — Not measured.
Records available. — May 5, 1915, to December 31, 1917. Station maintained at
Hinsdale, 8 miles upstream, from May 13, 1908, to November 13, 1914. Discharge
nearly same at both points.
Gage. — Sloping gage painted on concrete of right abutment downstream side of dam.
Read twice daily to tenths by employees of United States Roclaniation SerN-icw
it is diflicult to read gage closer than the nearest tenth as water conung through
sluice gate and over dam (>auses waves at gage.
232 WATER SUPPLY OP ST. MARY AND MILK RIVERS, 1898-191*7.
Discharge measurements, — ^Made from the bridge over crest of dam, from highway
bridge at Vandalia about 2 miles downstream, or by wading.
Channel and control. — ^Water surface at gage in large pool below dam is con-
trolled by gravel bar at medium and low stages. This bar is drowned out at
high stages. Both banks high; left is overflowed at high stages.
Extremes of discharge. — Maximum stage recorded, 34.5 feet April 11, 1917 (dis-
charge, 25,200 second-feet); channel reported dry August 9-13, 1910. (See hy-
drograph, PI. XX.)
Ice. — Stage-discharge relation affected by ice during winter season except for periods
of high water. The flow during the winter is fairly constant and can be estimated
from* the flow at Malta or from a few discharge measurements and daily gage
heights.
Diversions. — Numerous canals divert water for irrigation from main stream and
nearly all tributaries.
Regulation. — Flow partly regulated by the diversion dam at station and by storage
in Nelson reservoir.
Accuracy. — Stage-discharge relation not permanent; seriously affected by ice and
by shifting control. Daily gage heights are mean of two readings daily to nearest
tenth. Readings on the gage are difficult to make when gates are open and when
flow over crest is large; this condition may introduce errors. An automatic crest
on the dam keeps the water level above the dam fairly constant. It takes an
appreciable change in water surface above the dam to overcome the inertia in
these gates and so raise or lower them. As a result at low stages they tend to
remain fixed and so give a fairly constant discharge below. Gage heights subject
to error at medium and high stages when flow over crest of dam or through sluice
gates causes wave action on gage.

Note. — 1915: Discharge May 6, estimated; sluice gate was opened to allow a larger discharge for current-
meter measurement on this date, and was then closed. Flashboards put on dam Aug. 24. Daily dischaj-ge
estimated Nov. 20 to Dec. 2, on account of ice.
1916: Discharge Feb. 23 to Apr. 5 not computed because stage-discharge relation was affected by back-
water from ice, brush, and trees. Dee. 21-31, stage-discharge relation affected by ice; mean discharge
estimated 114 second-feet.
1917: Apr. 1-9, daily discharge estimated from discharge measurement Apr. 3.

Note. — Means for periods less than a full month but exceeding 15 days were considered means for the
month in finding average and median flow. The median flow given was obtained by arranging the monthly
means in their order of magnitude and taking the middle mean, or, if their nurhber was even, the average
of the two middle means. By using daily discharge a considerably lower median discharge would bo
obtained. The total yearly flow in acre-feet has been averagedj because in general the period of record
covers the open-water season, and the flow during months for wluch records are missing was usually small.
STATIONS ON TRIBUTARIES.
NORTH FORK OF MILK RIVER NEAR BROWNING, MONT.
Location. — In sec. 16, T. 37 N., R. 11 W., at Alexander Dubray's ranch, 35 miles north
of Browning and about 2 miles south of the Canadian boundary line, on the
Blackfeet Indian Reservation in Teton County.
Records available. — May 8, 1911, to July 6, 1912. *
Drainage area. — Not measured.
Gage. — Staff gage nailed to a post on right bank.
Channel and control. — Bed of steam composed of small gravel. Controlis a wide
gravel bar, and is likely to sliift at medium and high stages. Banks low; subject
to overflow during floods.
DiscHARdE MKAsuuKMiONTrt. — JVIado by wading at convoiiicMt socliouH near the gage.
Ice. — .Stream freezes over during the winter; winter gage heights have no value.
236 WATER SUPPLY OF ST. MARY AND MILK RIVERS, 1896-1917.
•
Accuracy. — Stage-discharge relation not permanent. Discharge measurements cover
only a small range in stage . Hydrographic comparison with records obtained at the
Canadian station at Peter's ranch for 1911 and 1912 indicates (1) that the observer
at Dubray's ranch, reading to tenths only, does not record small changes in stage,
(2) that the flow at Dubray's ranch is consistently lower than at Peter's ranch by
a considerable amount, and (3) that the records for August and September, 1911,
are of doubtful accuracy, owing to questionable gage readings. Records fair.

NORTH FORK OF MILK RIVER NEAR INTERNATIONAL BOUNDARY.i
Location. — In the NE. \ sec. 11, T. 1, R. 23 W. fourth meridian, about 15 miles
(by road) southeast of Kimball, Alta., 5 miles below spillway of the United States
Reclamation Service St. Mary canal, and about 2 miles north of the international
boundary. (See PI. XXI.)
Drainage area. — 101 square miles (measured on topographic maps).
Records available. — July 21, 1909, to December 31, 1917. From July 21, 1909,
to December 31, 1912, the station was about 2 miles farther downstream, in the
NE. \ sec. 13, T. 1, R. 23 W. fourth meridian, and was maintained by the Recla-
mation Service, Department of the Interior, . Canada.
Gage. — Stevens water-stage recorder on left bank, 1913-1917; vertical staff used 1909
to 1912 and for winter readings to 1916; chain gage installed in September, 1916,
was used for winter readings and as a check on water-stage recorder. Observer,
Charles Barnett.
Discharge measurements. — Made by wading, from footbridge 700 feet below gage,
or from cable 800 feet below gage.
Channel and control. — Bed of stream at gage and principal control formed of
clay and small boulders; slightly shifting. Banks low and subject to overflow at
flood stages. Control likely to shift during high water.
Extremes of discharge.— 1909-1917: Maximum stage recorded, 4.86 feet June 23,
1911 (discharge, 555 second-feet); a stage of 3.9 feet July 27, 28, 1909, gave a
discharge of 591 second-feet; minimum stage recorded, 1.97 feet December 7, 1915;
minimum discharge recorded, 5 second-feet February 12, 1916 (stage, 3.45 feet).
Ice. — Stage-discharge relation affected by ice.
Diversions. — None.
Regulation. — During July, August, and September, 1917, the flow was verj'- largely
regulated by the quantity of water turned into this stream from the United States
Reclamation Service St. Mary canal. This condition mil continue, as it is
expected that the canal will be permanently in use.
Accuracy. — Stage-discharge relation fairly permanent up to 191G; during 1916 and
1917 changed during high stages and by water from the United States Reclamation
Service St. Mary canal. Open-water discharge computed by applying mean
daily gage height to rating table and applying corrections for periods of shifting
control; winter discharge determined from hydrographs based on discharge meas-
urements, records of maximum and minimum temperature, and gage-lieight
graphs. Records fair.
CooPEiiATiON. — Station maintained jointly by the United States Geological Survey
and the Reclamation Ser\'ice, Department of the Interior, Canada.
» station formerly called "North Fork of Milk Rivor r\mr Kimball, Alta.," in reports published by the
United States Government and "North Branch of Milk River at Peters' ranch" in Canadian reports.

252 WATEE SUPPLY OF ST. MAKY AND MILK EIVERS, 1898-1917.
DEER CREEK AT DICKINSON'S RANCH, ALTA.
Location, — In SW. J sec. 15, T. 1, R. 12, W. fourth meridian.
Drainage area, — 7 square miles.
Records available. — Incomplete records of open water flow. May 26, 1911, to
November 7, 1911, and May 3, 1915, to October 31, 1915. Miscellaneous dis-
charge measurements in 1912, 1913, 1914, and 1916. (See pp. 561-570.)
Gage. — Vertical staff; read in 1915 by H. E. Sammons.
Discharge measurements. — Made by wading; at high stages could be made from
traffic bridge 200 feet above gage.
Channel and control. — Bed gravel with sand covering stones. Banks low, and
subject to overflow; right bank covered with brush; left bank clean and covered
with sand and gravel. Channel about 40 feet wide; in ordinary stages stream
is 6 to 10 feet wide. One channel at all stages. Stage-discharge relation is sub-
ject to great change in high water but apparently constant in low water.
Extremes of discharge. — 1911 and 1915: Maximum stage recorded, 3 feet, June
24, 1911 (discharge, 127 second-feet); minimum stage recorded, 1.58 feet, June
18, 1911 (discharge, 0.40 second-foot).
Diversions. — There are several diversions for irrigation below this station.
Accuracy. — Stage-discharge relation not permanent in 1915. Gage read once daily
to hundredths. Two rating curves made because of shifting control, but 14
measurements were made and rating curves are well defined between gage
heights 1.60 feet and 2 feet. Daily discharge determined directly from curves.
Records for period good.

268 WATER SUPPLY OF ST. MARY AND MILK RIVERS, 18£>8-1917.
LODGE CREEK NEAR CHINOOK, MONT.
Location. — In sec. 26, T. 33 N., R. 19 E., at highway bridge half a mile east of
Chinook, Mont., in Blaine County. July 1, 1907, to April 16, 1908, station was
in sec. 15 or 16, T. 33 N., R. 19 E., at the Rainholt ranch, 2 miles upstream.
(See PI. XXI.)
Drainage area, — Not measured.
Records available. — April 9, 1906, to June 30, 1908.
Gage. — ^The original gage was an inclined staff 170 feet above the bridge. An exten-
sion consisting of a vertical rod reading from 14 to 19 feet was installed April 25,
1906. On June 27, 1906, a chain gage was installed on the upstream side of the
highway bridge. On July 1, 1907, a new gage was installed at the Rainholt
ranch of the Empire Cattle Co., 2 miles upstream; this gage was used July 1, 1907^
to April 16, 1908, when readings were resumed at the highway bridge.
Discharge measurements. — Made from highway bridge or by wading.
Channel and control. — Bed composed of gravel and mud; likely to shift. Back-
water from Milk River affected stage-discharge relation during floods on Milk
River.
Ice. — Stream freezes over during winter months but there is practically no flow.
Diversions. — West Fork ditch diverts about 4 miles north of Chinook. The first
diversion was made in 1898. There are also other small diversions both in Canada
and the United States. Water from Fort Belknap canal is at times wasted into
the creek below the Rainholt ranch but above the highway bridge.
Regulation. — None.
Accuracy. — Stage-discharge relation not permanent; affected by backwater at high
stages in Milk River. Records fair.
