2021 Map of Calaveras Reservoir

About this map

The eastern edges of San Jose and Milpitas meet the rising slopes of the Diablo Range in this recent survey. Urban residential growth in Berryessa and the East Foothills transitions into a network of watershed lands and mountain peaks. Centered on the Calaveras Reservoir, the map traces the critical water infrastructure of the S Bay Aqueduct and the drainages of Arroyo Hondo and Calaveras Cr. Local history is anchored by Saint Johns Catholic Cem and the recreational geography of Alum Rock Canyon. High points like Monument Peak and Mt Allison define the horizon above the Calaveras Valley, illustrating the persistent divide between the dense Santa Clara Valley floor and the protected open spaces of the Los Buellis Hills.
