Completed in 1952 on the Clark Fork River, Cabinet Gorge
possesses the second-largest generating capacity of any of Avista's eight
hydroelectric developments. Constructed to help solve the critical Northwest
energy shortage of the late 1940s and early 1950s, the concrete arch dam
was completed only 21 months after its initial groundbreaking. A total of
1700 men and women worked 24 hours a day to excavate 785,000 cubic yards
of rock and pour 240,000 cubic yards of concrete!
Just off Highway 200, and located on a cliff directly overlooking the dam
and powerhouse, a landscaped viewpoint is open to the public during the
non-winter months. Although the dam and powerhouse are located in
northeastern Idaho, most of the reservoir lies in Montana. The area
surrounding the reservoir offers abundant camping and wildlife viewing
opportunities.
In cooperation with federal and state agencies such as the U.S. Forest
Service and Montana Fish, Wildlife, and Parks, Avista has developed many
recreational sites along the reservoir. In a joint 1985 effort with the
Bonneville Power Administration and the Idaho Department of Fish and Game,
Avista helped construct the Cabinet Gorge Fish Hatchery (which primarily
produces young Kokanee). Operated by Idaho Fish and Game, the hatchery is
located approximately one mile downstream of the dam, and is open for
public tours.
