De three tunnels having total

On the south branch canal
in addition to the earth canal
there will be approximately 800

The water supply for the district
will be from the Yakima river and
from storage in lakes Kachess and
Keechelus on the headwaters OF the
river. These lakes are now being
converted into storage reservoirs
through the erection OF large stor-
age dams by the Reclamation serv-
ice Of the United States.
When completed the former will
have capacity Of l65,O 900 acre
feet and the latter 1900 acre
feet. The lakes are fed principal
ly by the melting snow in the
mountains near the summit Of the
Cascade range The depths Of
snowfall frequently aggregates IS
to 80 feet in one season. During
the periods OF high water in the
spring Of the year, the canal will
be supplied by the surplus waters
Of the Yakima river.
The headworks OF the Kittitas
Reclamation district canal. popu-
larly known as the high line canal,
will be located about one half mile
west of Easton and three miles be-
low the Lake Kachess reservoir.
Water will be diverted from the
Yakima river at an elevation of 2.
rs feet by a concrete dam $50
feet long and so feet high. From
this point the main canal follows
down the south side Of the river a
distance of twenty-six miles, where
it divides one branch crossing the
Yakima river to the north side.
and the other continuing around
the south side of the valley to Man
astash creek. The north branch
has total length of fifty miles,
and the south branch about four
teen miles, making a grand total
of ninety miles.
Of the total area under tho canal
of 81 900 acres, 10000 acres are
under the main canal between
Easton andthe Yakima river cross
ing; 81 900 acres under the north
