Barrett Lake dominates this mid-century survey of the Cleveland National Forest, serving as a central hub for the region's complex water management infrastructure. The map details the critical San Diego City Conduit and San Diego City Tunnel systems, which trace the movement of water south from the Barrett Dam spillway. The landscape is defined by rugged peaks like Lawson Peak and Mother Grundy Peak, while the valleys are dotted with established homesteads and operations including Eichenlaub Ranch, Walker Ranch, and Bratton Ranch. Small-scale water retention is evidenced by the Henry Jr Dam and Mary Jo Dam to the northeast. Transportation through this backcountry relies on a network of named routes such as Japatul Road and the Deerhorn Grade, providing access to remote locations like the Barrett Honor Camp.
