The f i e l d work inc iden ta l t o the d iv i s ion and
administrat ion of
the waters of the St . Mary and Milk Rivers i n Albrta,
Saskatchewan and
Montana was conducted during the i r r i g a t i o n season of
1963 by representa-
t i v e s of the United S t a t e s Geological Survey and the
Water Resources Branch
( ~ a n a d a ) . D r . L. 8. hopold , Chief Hydraulic Engineer,
United States Geological
Survey, as accredited o f f ice r of the United S ta tes , was
represented i n the

Montana. Mr. J. D.
McLeod, Chief Engineer, Water Resources Branch, Department of
Northern
Affa i r s and National Resources, ac t ing i n the capacity of
accredited

by Mr. R. D. by,
D i s t r i c t Engineer, Calgary, Alberta.
This repor t has been prepared j o in t l y by Mr. F. Stermitz
and Mr.

The waters of the two r i v e r s were. divided between the two
countries
i n accordance with the Order of the In te rna t iona l J o i n

during the i r r i ga t ion
season 1 A p r i l t o 31 October. The natural flow during the i

The forty-second annual in ternat ional survey of snow

1 May, 1963.
The survey provided advance information on the probable run-off

DIVISION OF WATER
St. W.v Wmr
The d iv i s ion of the waters of the St . Mary River was car r
ied out
i n accordance with the Order of the In te rna t iona l J o i n
t Commission dated
. , October 4, 1921. The d a i l y na tu r a l flow of the St .
Mary Rimr was determined i n
the following mamqer. Daily records were obtained a t St. M j r
Canal at
St . Mary Crossing near Babb, S t . Mary River a t Internat
ional Boundary,
Iake Sherburne a t Sherburne and an evaporation and prec ip i ta
t ion s t a t i o n
near Babb, Montana.
The na tura l flow of the St . Paary River a t the international
boundary
wne considered t o be the sum of the quan t i t i e s masured a
t St. Mary Canal
at St. Mary Crossing near Eabb, St. Mary River a t In te rna t
iona l Boundary
and addi t ion o f storage or subtraction of release corrected f
o r evaporation
a t Lake Sherburne . A one-day time l ag was applfed t o atored
and released quan t i t i es
from Iake Sherbunre t o synchronim the flow with flow quan t i t
i e s a t the
in te rna t iona l boundary.
The na tu ra l flow of the St. &y River having been
determined,
the d iv i s ion of its waters was car r ied out i n accordance
with the above
Order, as shown i n Tables 5 t o 8 inclusive,
During the i r r i g a t i o n season, 1 April t o 31 Ootober, f
i e l d
eng imer s of both countr ies made frequent computations of the
da i ly
natural flow of the r i v e r and each country 's share thereof
, i n order
t h a t any appropriat ion by the United S t a t e s i n excess
of t h e i r share
oould be adjusted by a subsequent de l ivery t o Can& of an
equivalent
amount a t the e a r l i e s t opportunity.
-
Regular interim reports on the progress of the division of
the
natural flow a t the international boundary w e d made t o
interested agencies
throughout the i r r iga t ion mason.
During the non-irrigation season, 1 November 1962 t o 31 PlIarch
1963,
no interim reports were made as the only United S t a b s use
during t h i s
period was etorage i n Lab Sherburne, where the contributing
drainage area
is about %percen t of the t o t a l area of the St. Mary River
drainage basin
i n the United States.
Storage i n Lake Sherburne was 15,500'acre-feet on 31 October
1962
and had increased t o 38,470 acre-feet by 31 March 1963 and t o
66,130 aom-
f ee t by 15 July 1963. On 31 October 1963 tla, storage was
6,400 . . . acre-feet. . .. ...
The St. Mary Canal was operated between 3 A p r i l and 23
September
and water was delivered t o the [Jorth Milk River f'rom 4 April
t o 1 October.
Seepage From the canal between the point of diversion and the
crossing
of the St. Mary River is assumed t o return to the r i v e r and
eventually be-
come available t o Canada. The discharge of 224,200 acre-feet
which passed
the gauging s ta t ion on the St. Pllary Canal a t St. Mary
Crossing near Babb .
between 3 Apri l and 23 September was considered t o be the
quantity diverted
k o m the St. Mary Rimr by the United States. A t o t a l of
219,200 acre-feet
was delivered t o the North Milk River a t Hhdaon Bay Divide
during the season,
fkom where, it was conveyed to i r r iga t ion projects i n
Montana v i a the Milk

No divis ion of the flow of Milk River a t 'Eastern Crossing was
made
i n 1963. Except f o r a few s d l unmeasured diversions above
the eastern
crossing of the internat ional boundarg, the en t i r e natural
flow of the
Milk River a t t h a t point was delivered t o the United
Statee,
The United S ta tes Geological Survey began streamflow record
col lect ion
i n 1961 on the South Fork Milk River near Babb to a s s i s t i
n studying the
u t i l i z a t i o n of waters i n the K l k River Basin within
the Blackfeet 1ndian
Reservation. This s t a t i on was designated a s in te rna t
iona l i n 1963.
Some concern has been expressed i n Canada as the result of
prolonged
periods of inadequate supply f o r stockwatering along the Milk
River above
the mouth of the North Milk River.
No flow was recorded from the 7 August t o 31 October, with
the
exception of small flows on the 25 and 26 August, i n the Milk
River a t
the western crossing of the in te rna t iona l boundarg.
A report t o the Internat ional Jo in t Commission has been
prepared
by the United S ta t e s Geological Survey on the Ut i l i za t
ion of Water8 i n
the Milk River Basin within t h e Blackfeet Reservation,
Montana.
Stream gauging s ta t ions within the area were operated joint
ly by
the United S ta t e s and Canada during the 1963 season,

Gastern Tributaries of Milk River
Minor Diversions: l&timates for a number of small diversions
from
the eastern t r ibutar ies of PIZiUr River i n Saskatchewan were
provided by
the Water Rights Division of the Province of Saskatchewan and
are based
on reports from the individual licensed i r r iga tors . These
estimates are
not used i n the Indge Creek division computations i n Table 2,
except as
an adjustment t o the t o t a l s fo r tile season. The
estimated quant i t ies
reported t o date for 1963 are detailed i n the Appendix t o t h
i s report.
M m Creek8 The computed natural flow of Lodge Creek a t the
inter-
national boundary f o r the period 1 k c h t o 31 Octobar 1963
was 11,560
acre-feet of whioh each country was en t i t l ed t o f i f t y
percent (5,780).
%The de ta i l s of t h i s divis ion are summarized i n Table
2, and shown i n
Tabb 9.
A t o t a l of 6,080 asre-feet was recorded a t the
international boundary,
which is 105 per cent of the United Sta tes share.
Battle Creek: The computed natural flow of Batth Creek a t
the
Snternational boundary f o r the period 1 March t o 31 October
1963 was
8,040 acre-feet of which each country was en t i t l ed t o f i
f t y p e r cent
(4,020). The details of t h i s division are3 summarilred i n
Table 2, and
shown i n Table 10.
A t o t a l of 4,700 acre-feet was recorded a t the internat
ional
boundary, whieh is 117 per cent of the United Sta tes share.
Miecellaasous meaemments were made on Battle Creek during
the
season. It is hoped t h a t a fur ther and more comprehensive se
r i e s of
measurements in future years mag provide some def in i te
figures fo r
computing channel lossea and return flow.
-
Frenchnan River: The computed natural flow of the Frenchman
River a t
the international boundary fo r the period 1 March t o 31
October 1963 was
46,800 ncre-feet of which each country was ent i t led t o f i f
t y per cent
(23,400). The d e t a i l s of t h i s division are summarized i
n Tnbb 2 And
shown i n Table 11,
A t o t a l of 33,880 acre-feet.was recorded a t the internat
ional boundary
which i s 145 per cent of the United States share,
The natural f l o w of the Frenchman River a t the internat
ional boundary
was computed using a nine-day time l a g f o r Cypress Lake
storage and diver-
sion, sevenday time lag fo r Eastend Reservoir storage and
diversion, and
a th reeday time l a g fo r Val Marie storage and diversion, to
synchronize
the flow wi th flow quanti t ies a t the international
boundary,
During 1963 a channel lo s s study was implemented on the
Frenchman River,
Measurements were taken a t a p p r a b a t e l y t h i r t y a
f f e r e n t s ta t ions on the
Frenchman River and i t s t r ibu ta r i e s during June,
September and October,
Due t o web weather the resu l t s of the three ser ies of
measurements carried
out t h i s year were inconclusive, but it w a s f e l t t ha t
several more s e r i e s
during 1964 and i n future years may help i n computing channel
losses a t
low flows,
An Appendix, submitted with t h i s report under separate
cover,
contains the resul t of discharge measurements, summary of
monthly dis-
charge and the da i ly gauge height and discharge data for 60
