SYNOPSIS

releases from the Castilla plant would flow down Spanish Fork River to
Utah Lake, relieVing the obligation of Provo River to deliver water to
the lake. So far as practicable throughout the year releases from the
Castilla plant would be routed through existing power plants of the
Strawberry Valley project, thus providing a much needed firm water
supply for operation of these plants.

Provo River water replaced in Utah Lake by water from the Central
Utah project would be stored in the potential 65,000 acre-foot Bates
Reservoir on the Provo River ,and the potential 850 acre-foot Hobble Creek
Reservoir on a tributary of Round Valley Creek. The operation of these
reservoirs would be correlated with that of the Deer Creek Reservoir and
other existing reservoirs on the Provo River system to the mutual advan-
tage of present and potential water users. The Central Utah project
water from the Provo River would be used for irrigation, municipal, and
industrial purposes in the Heber-Francis-Wallsburg areas and in the
Provo-Salt Lake City region. A portion of this water would be conveyed
to lands in the western part of the Jordan River Valley through the
existing Provo Reservoir Canal and the potential West Valley Canal.
Another portion would be conveyed by the Provo Reservoir Canal and used
for irrigation and other purposes in the area from Provo to Lehi. The
remainder would be utilized for muniCipal, industrial, and other miscel-
laneous purposes in areas between Lehi and Salt Lake City. This water
would be conveyed from Provo River through the Salt Lake aqueduct, con-
structed by the Bureau of Reclamation l"S a part of the Provo River
project. Central utah project water conveyed in the aqueduct would be
regulated to meet fluctuating d€lllands in the potential 490 acre-foot
Front Reservoir located one-half mile south of the mouth of Big Cottonwood
Creek near Salt Lake City. AI!I an addition to use of the Salt Lake aqueduct,
a potential mine-drainage tunnel that would serve the important Park City-
Alta mining district also could be utilized for the delivery of Central
Utah project water in the Provo River to the Vicinity of Salt Lake City.
Use of the tunnel, however, is not included in present plans of the
Bureau of Reclamation. Existing irrigation distribution systems would be
rehabilitated and extended in the Heber and Walls burg areas.

Dams would be constructed where practicable to impound water for
recreational and fish and wildlife purposes, thus providing partial com-
pensation for damages to these purposes from the construction of some
other project features. Included would be a dam forming Round Knoll Lake
near Wallsburg, which would provide a constant water surface of 300 acres.
Fish hatcheries would be constructed to provide fish for stocking streams
as further compensation for damage resulting from the project.

A dike 6.7 miles long and 20 feet high would be constructed across
the mouth of Provo Bay, an ann of Utah Lake. Tl1e bay would then be
drained to reduce evaporation losses and to reclaim 9,340 acres of land
for irrigation farming. An irrigation supply for the area would be
