1944 Map of Potrero

About this map

Potrero serves as the focal point of this 1940s topography, situated in a valley south of the Cleveland National Forest. The map documents a critical infrastructure network for San Diego's water supply, dominated by the reservoir at Barrett Lake and the Barrett Dam, alongside Lake Morena to the east. Along the southern border, the international boundary with Mexico is clearly marked, featuring the border crossing at Tecate and its Custom House. The transit corridor is defined by the San Diego & Arizona Eastern railroad, which follows Campo Creek through Canyon City. Local civic life is anchored by rural institutions like the Potrero Sch and Barrett Sch, while family-named landmarks such as the McAlmond Ranch and Stokes Valley suggest the ranching character of the landscape during the war years.
