2015 Map of Clifton Court Forebay

About this map

Clifton Court Forebay and the surrounding delta landscape define this region where the borders of San Joaquin, Contra Costa, and Alameda counties meet. The map documents an intricate network of water management infrastructure, including the Governor Edmund G Brown California Aqueduct, the Delta-Mendota Canal, and the Bethany Reservoir. These engineered waterways cut through a natural geography of islands and sloughs, such as Victoria Island, Union Island, and Italian Slough. In the southern portion of the map, the residential development of Mountain House is visible, showing a planned grid of streets like Great Valley Pky and De Anza Blvd. The transition from the flat delta lands to the rising foothills near Mountain House Creek provides a clear view of the area's topographical shift, while the presence of Byron Airport in the northwest marks a modern transportation hub.
