2018 Map of Almanor

About this map

The Almanor Peninsula and the western shores of Lake Almanor define this high-country landscape where the Lassen National Forest meets the Plumas National Forest. The settlement of Almanor and the community of Prattville serve as primary points of interest along the shoreline, while the isolated Longville sits further west near Soda Spring. The topography is shaped by the transition from the lake's edge to the deep drainage of the Butt Valley Reservoir, connected by the Butt Valley Tunnel and several prominent creeks including Butt Cr and Yellow Cr. A complex network of forest roads, such as Humboldt Rd and Humbug Rd, provides access to the interior, where the Red Rock site stands as a legacy of local mining activity. This geography highlights the late-20th-century development of leisure-oriented lakeside neighborhoods alongside established forest service management and hydroelectric infrastructure.
