1955 Map of San Vicente Reservoir

About this map

San Vicente Reservoir dominates the center of this 1950s landscape, its jagged shoreline and Spillway 650 illustrating mid-century water management in San Diego County. The infrastructure is further detailed by the San Diego Aqueduct Tunnel, which cuts through the highlands south of Iron Mtn. The map reveals a transition from ranching to suburban and military utility, as the Camp Elliott Naval Reservation occupies the southwest corner and the Barona Indian Reservation borders the eastern edge. Small communities and named ranch lands like Eucalyptus Hills, Muth Valley, and Goodan Ranch provide key reference points for local history. Several quarries and a Gaging Sta reflect the industrial and hydrological development of the era, while named peaks and canyons like Vallecitos and Beeler Canyon provide the topographic context for these developments.
