Whitman Lake Hydroelectric Project

CLIENT:

City of Ketchikan

LOCATION:

Ketchikan, Alaska

ARCHITECT:

Hatch Associates Consultants, Inc.

DESCRIPTION: Phase one construction of the Whitman Lake Hydroelectric Project included temporary hatchery water supply bypass, access trail and laydown, powerhouse and tailrace structures, switchyard, powerhouse crane, hatchery head tank, intakes and valve house and pipelines from dam to powerhouse. A new 2,400 sf power house was constructed, and ½ mile of new pipe line for water supply to the power house.

Phase 2 is referred to as the Achilles Diversion. This includes a new access road and bridge up to Achilles Creek where a dam and reservoir will be built. New water lines will run from the dam and tie into lines from phase one. This will increase the water supply for generation at the existing powerhouse (built in phase 1).
