600 acres without a sufficient water |
supply.
Works for South Side Boise Di,i.
slOn-lt was finally decided to utilize |
the New York canal by eularging and |
extending it and making it the main |
canal on the south side of the Boise |
valley. This main canal will divert |
water from the Boise river eight miles |
above Boise, near the mouth of the
canyon. Its course from this point
will run southwesterly to Indian
creek, a distance of 26 miles. The
major portion of its discharge will be
dropped into Indian creek, down
which it will flow for a distance of
about nine miles to point about four
miles southeast to Nampa At this
point 1t will be diverted in a canal and
conducted to the Deer Flat reservoir
a distance of about IA miles. This
canal has capacity of 1900 second
feet from the point of diversion to the
reservoir. 1t has been constructed,
however, with view to enlarging 1t
at some future time to capacity of
200 second feet, which will provide
for filling the reservoir in the shortest
possible time, as we'll as provide for
the irrigation of all the lands lying
below its level. The capal is now
practically completed and will be
ready for full use next season. A di-
vertng dam in the Boise river at the
head of the canal is now nearing COM
pletion. This dam has cost more than
$250,000 and is of solid masonry with
timber apron. 1t is $50 feet long
between abutmentS and the crest is
eight feet above the bottom grade Of
the canal, and will raise the surface
81 feet above present low water. Con-
siderable power could readily be de-
veloped at this point, which could be
used for pumping water on to higher
lands or for municipal or other pur-
poses.
Deer Flat ReseryOir-One of the
most remarkable features of the work
in this division Is the Deer Flat res
ervoir. 1t contains an area Of $3.50
acres and has total capacity of 1885,
900 acre feet. 1t was necessary to
construct two dams; one, the upper
embankment, having maximum
height of CTS feet and total length
of 400 feet; the other, the lower EN-
bankment, having a maximum height
of AIS feet and a length of 1900 feet
The reservoir will have a minimum
depth of 60 feet at the upper en-
bankment and 33 feet at the lower
Each of these entertainments contain
about 100000 cubic yards of eartl
and gravel. The lower one was bull
by contract and finished last January
the upper one is under construction
by the reclamation service and will b.
completed. About 100000 acres o
bench lands are tributary to this res
ervoir. Water can be delivered t
about 10000 acres on the first bottor
of the lower Boise valley in additio
to this area.
Construction of Distributing SysteI
The works which have thus far bee
, constructed cost nearly $2.00O,oO'
: which is considerably more than wa
originally allotted to this project.
