1951 Map of Clear Lake Reservoir

About this map

Clear Lake Reservoir and its surrounding high-desert plateau dominate this 1951 survey, situated along the State Line of California and Oregon. The map documents a landscape defined by water management and ranching, where the Lost River enters from the north and various springs like Mammoth Sprs and Fiddlers Green sustain local holdings. This era shows the established presence of the Clear Lake National Wildlife Refuge and Modoc National Forest, protecting the habitat around Bird Island.
