1952 Map of Bouldin Island

USGS Topo · Published 1964

About this map

Bouldin Island and the surrounding reclaimed tracts form a complex deltaic landscape at the junction of the Mokelumne River and the San Joaquin River. This 1952 topographic survey details the extensive levee systems, siphons, and pump houses necessary to maintain these low-lying agricultural tracts, including Webb Tract and Venice Island. The vast expanse of Franks Tract stands out as a significant water body, reflecting the region's history of land subsidence and flooding. Navigation is a central theme, evidenced by the Stockton Deep Water Channel and markers like the Prisoners Point Bend Light. Small pockets of settlement and infrastructure are visible at Little Venice and the Venice-Mandeville School, serving the labor and families tied to the river-and-rail economy of the central California delta.
