1953 Map of Calaveras Reservoir

About this map

Calaveras Reservoir dominates the center of this landscape, its waters controlled by a Diversion Dam and a Diversion Tunnel leading from Alameda Creek. The map documents a pivotal moment in the Santa Clara Valley's transition, showing the agricultural grid of the Pueblo Lands of San Jose meeting the burgeoning residential development near Berryessa. While the eastern hills remain largely open ranch land divided by family holdings and Mexican land grants like Tularcitos (Higuerra), the southwestern corner reveals the early suburban footprint of Alum Rock. Cultural landmarks such as the San Jose Country Club and Alum Rock Park are clearly defined alongside rural infrastructure including the Air Point Sch and a scattered network of gravel pits and water tanks that supported the region's mid-century growth.
