1961 Map of Calaveras Reservoir

USGS Topo · Published 1965

About this map

The Calaveras Reservoir dominates the northern terrain of this 1961 field-checked survey, illustrating the complex water management infrastructure of the Diablo Range. Fed by Arroyo Honda and Calaveras Creek, the reservoir is supported by a Filtration Plant and proximity to the Calaveras Test Site. Further south, the landscape transitions from the steep grades of Oak Ridge and Poverty Ridge into the growing suburban and agricultural outskirts of San Jose and Milpitas. This era shows the early expansion of neighborhoods like Berryessa and Alum Rock, where the city grid begins to climb the foothills of the Los Buellis Hills. Civil and social infrastructure is well-marked, including the San Jose Hospital, Spring Valley Golf Club, and local education centers such as Air Point Sch and Piedmont Sch. Extensive public land use is evident in the detailed mapping of Alum Rock Park and the historic Pueblo Lands of San Jose.
