About this map

Bouldin Island and the surrounding reclaimed tracts of the California Delta are depicted here following mid-century surveying, showing a landscape defined by an intricate network of levees, siphons, and pump houses. The map illustrates the specialized water management required for agriculture and transit in the San Joaquin and Sacramento river systems, featuring the industrial Stockton Deep Water Channel alongside recreational waters like Franks Tract State Recreation Area.

Local life is anchored at the Venice-Mandeville School and small residential clusters like the Trailer Park on Andrus Island. Navigational markers such as the Prisoners Point Bend Light and various beacons emphasize the delta's importance as a maritime corridor. The presence of numerous named sloughs, including Potato Slough and Sand Mound Slough, highlights the complex hydrology where three counties — Sacramento, Contra Costa, and San Joaquin — meet among the shifting channels and shoals.
