About this map

Lake del Valle serves as a focal point for this section of Alameda County, its waters held by the Arroyo Valle and framed by Heron Bay. This modern topographic survey illustrates the extensive recreational infrastructure surrounding the reservoir, including sites like the Oak Point Picnic Area, Ardilla Group Camp, and the Punta Vaca Caravan Camp.

Infrastructure for water management is clearly marked by the subterranean path of the Hetch Hetchy Aqueduct as it traverses the terrain toward the Bay Area. To the east, the landscape rises into the ridges of the Diablo Range, home to the local landmark Mendenhall Springs and the nearby Mendenhall Ranch. The map also details the high points of the region, specifically Rose Peak and Discovery Peak in the southern reaches, providing a clear view of the drainage patterns of San Antonio Cr and Indian Cr.
