Irrigation Plan.
The irrigation plan on the Boise
Propect provides for storage of water
III the Arrowrock Reservoir on Boise
river about 20 miles above Boise and
in the Deer Flat reservoir near Nam
pa and Caldwell Idaho; the diversion
of water from the Boise river by the
Boise river dam about miles above
Boise; the distribution of water on
the south side of Boise river through
the main canal leading from the dam
to the Deer Fiat reservoir and through
canals heading into the main canal
and the Deer Flat reservoir and into
the Boise river below the Boise river
diversion dam. The irrigation plan
also provides for the distribution of
water on the north side of the Boise
river to a small area of land east OF
BOISE through canal system head
ing into the river at the Boise river
diversion dam. The Boise river di-
version dam, the Deer Flat reservoir,
and the canal systems on the north
and south side of the Boise river are
now complete. About 10000 linear
feet OF the main canal have been con-
crete lined with a base width of 40
feet, and about $4,000 linear feet have
been enlarged to a base width of
~ feet. The remainder of the main
canal, which includes that portion
OF the main canal between Indian
creek and the Deer Flat reservoir.
remains as originally constructed
with base width of 40 feet in an
earth section.
Water Supply.
The source of water suDDly for
the Boise Project is the Boise river
which has drainage area of 26lO
square miles The maximum run-off
of record is 100000 acre-feet. the
minimum POO 900 acre-fect. win =
mean OF about 100000 acre-feet.
About $1,000 acres or approximately
one-thlrd of the new lands embraced
ny the Boise project lie below the
Deer Flat reservoir and have a com
Flete water supply throughout the ir
rlgatlon season, or between April IS
and October Is. The balance of the
land under the project lies above the
Deer Fiat reservoir and is dependent
on Nrrowrock storage for late water
for the present, therefore, these lands
only receive flood water and such late
water III rotation as can be secured
though exchange of Deer Flat res

formally opened and probably will not
