months. This will make avail
able large blocks Of secondary
energy during the irrigation sea-
son from the potential Columbia
River power developments. Three
potential irrigation projects, one
with two large units, would uti-
lie this secondary power to irrl-
gate lands along the Columbia by
pumping from the river.
The Horse Heaven Unit OF the
Umatilla Rapids Project would
involve irrigation of about 49,
200 acres of new land in Wash
ington, lying adjacent to the river
west of the proposed McNary
DAM. The area would be served
by pumping.
The Cold Springs Unit of the
Umatilla Rapids Project, consist
ing of approximately SO, 700 acres
in Oregon lying near the Column
bia, east of the Hermiston and
Stanfield Irrigation Districts, also
would be served by pumping from
the McNary Reservoir.
Water would be pumped from
the reservoir above Arlington
Dam to irrigate 1850 acres of
benchlands in the Arlington Prof.
ect in Oregon, lying east of Alkili
Canyon and west of Willow Creek
and Eight Mile Canyon. The
Roosevelt Project, consisting of
$500 acres in the vicinity of
Roosevelt, Washington, would be
irrigated by pumping from the
reservoir behind John Day Rapids
Dam.
Power installations proposed on
the main stem would include The
Qalles, 659,OOO kilowatts; John
Day Rapids, 100000; Arlington,
100000; and McNary Dam, &C.,
600.
Walla Walla River Basin.-In
the. Walla Walla River Basin, con-
struction of two storage dams in
the Milton-Freewater Project
would provide supplemental water
for $4,000 acres and a full sup
ply to $500 acres of new land.
Through construction of Wicker
sham and Blue Creek storage
projects on Mill Creek, tributary
of the Walla Walla River, 1900
acres of inadequately irrigated
land could be served through the
Walla Walla Project.
The Dayton Project on the
Touchet River, a tributary of the
Wa1la Walla, would be provided
with supplemental water supply
for 5000 acres and a full supply
for $500 acres, through construc-
ton of a reservoir on the East
Fork, four miles above Dayton,
Washington.
Umatilla River Basin. - The
leading development proposed in
the Umatilla River Basin is the
Pendleton Project, which would
involve the irrigation of 24,2OO
acres of benchlands in two units.
one east and the other northwest
OF the city of Pendleton. A reser-
voir of $1,000 acre-feet capacity
on Ryan Creek on the Umatilla
River would be used partly for
irrigation storage and partly for
flood control.
John Day River Basin-The
water resources of the John Day
basin afford opportunities for
large irrigation developments.
Proposals include the irrigation
of 233, 500 acres of new land and
the provision of supplemental
water for 23,100 acres now irri-
gated.
The need for supplemental ir-
rigation water for 1920 acres on
the main stream can be met by
storage at the Hall Hill Reservoir
near Prairie City. Fox Gorge
Reservoir would provide supple
mental water for 500 acres of Cot
fonwood creek near Monument,
and Magcon Lake Reservoir would
supply supplemental water for
500 acres on Cottonwood Creek
near Monument, and Magoon
Lake Reservoir would supply sup
ienental water to 400 acres of
Land irrigated from Beach Creek
near Mount Vernon.
