2018 Map of Calaveras Reservoir

About this map

Calaveras Reservoir lies at the heart of this landscape, situated within the Calaveras Valley and fed by the Alameda Cr via the Alameda Diversion Tunnel. The terrain is defined by the sharp rise of the Diablo Range, including prominent heights such as Mt Allison and Monument Peak. Along the western edge, the urban expansion of San Jose, Milpitas, and Fremont meets the rising terrain of the East Foothills. This boundary between the dense residential street grids of Berryessa and the undeveloped highlands is marked by landmarks like the Saint Johns Catholic Cem and the steep walls of Alum Rock Canyon. These upland areas are crossed by numerous paths, such as the Sierra Vista Trail and Ridge Trail, reflecting a transition from suburban development to managed watershed and wilderness.
