1953 Map of Calaveras Reservoir

USGS Topo · Published 1955

About this map

The hills of the Diablo Range dominate this mid-century survey, defined by the expansive Calaveras Reservoir and the deep drainage of Alameda Creek. In the southwest, the valley floor shows the early urban footprint of Berryessa and Alum Rock before the rapid suburban expansion that would eventually characterize the region. The landscape reflects a mix of ranching heritage and water management, with Pueblo Lands of San Jose and the Ex Mission San Jose boundary marking historical land grants. Significant water infrastructure is visible, including a Diversion Dam and Diversion Tunnel feeding the reservoir. Local education and recreation are represented by the Air Point Sch and the San Jose Country Club, while the rugged eastern terrain is carved by Arroyo Hondo and Arroyo de los Coches.
