USGS Topo · Published 1979About this map
Lake Almanor and the surrounding timberlands of the Lassen National Forest define this 1970s landscape in Plumas County. The map details a sophisticated hydroelectric system, tracing a tunnel and penstock from the lake down to a powerhouse at the head of Butt Valley Reservoir. Small settlements like Prattville and Almanor sit along the southwestern shore, while historic transportation routes like Humboldt Road and Humbug Road cut through the heavy forest cover.
