About this map

The Sacramento-San Joaquin River Delta landscape is defined by the winding course of the Old River and Middle River, where a network of levees and sloughs separates expansive agricultural tracts like Woodward Island and Bacon Island. This 2021 survey shows the modern residential growth of Discovery Bay to the west, a waterfront community characterized by its extensive canal systems and bays such as Lido Bay and Cabrillo Bay.

Infrastructure is central to this region's function, highlighted by the industrial line of the Mokelumne Aqueduct crossing from Bixler through Orwood. The map captures the meeting of maritime and land transport, from the quiet waters of Latham Slough to the rural roads of the Holland Tract Rd. Smaller landmarks like the Las Serpientes Airport near Werner offer specific points of interest for local historians studying the transit patterns of Contra Costa and San Joaquin counties.
