ENVIRONMENTAL IMPACT STATEMENT

DIAMOND FORK POWER SYSTEM,
BONNEVILLE UNIT,
CENTRAL UTAH PROJECT

Prepared by:
Upper Colorado Region
Bureau of Reclamation
U.S. Department of the Interior

In cooperation with:
U.S. Department of Agriculture
Forest Service

Western Area Power
Administration

This Environmental Impact Statement (EIS) analyzes the environmental
impacts of alternatives being considered to deliver increased amounts
of water from the enlarged Strawberry Reservoir through the Diamond
Fork drainage in north-central Utah for hydroelectric power generation
and for agricultural and municipal and industrial purposes for both
the Municipal and Industrial System and the Irrigation and Drainage
System of the Bonneville Unit. Alternatives assessed include Fifth
Water Pumped Storage Alternative (the recommended plan); Sixth Water
Flow Through Alternative; Sixth Water Pumped Storage Alternative; the
1964 Definite Plan Report Alternative; and the No Power Alternative.
Depending on the plan selected, hydroelectric power generation could
amount to about 1,147 megawatts. The key issues raised in the scoping
process and discussed in the EIS relate to water and electrical energy
requirements J road and transmission alinements, recreation and tourism
and increased opportunities for stream and flat-water fishing, construc-
tion impacts on fish and wildlife, flood damage and erosion, and payment
for acquisition of property. A loss of existing wildlife habitat on
project lands would occur through a combination of reservoir inundation
and construction and operation of project features, primarily roads.
Wildlife mitigation plans are included as a part of all alternatives to
offset the loss of the wildlife values associated with this habitat.

This EIS is intended to serve environmental review requirements in
compliance with the Clean Water Act of 1977 (Public Law 95-217); Execu-
tive Order 11988, Floodplain Management; and Executive Order 11990,
Protection of Wetlands. The statement is also intended to fulfill
requirements for exemption from Section 404 of Public Law 95-217.
