About this map

Bouldin Island and the intricate Sacramento-San Joaquin River Delta define this 1908 survey, capturing a landscape of levees and reclaimed marshland tracts. Navigable water serves as the primary artery for commerce and transport, evidenced by waterfront sites like Central Landing and Blakes Landing. The presence of an Old Cannery along the South Fork Mokelumne River points to the region's early industrial reliance on river-based exports.

Water management is the central theme of the terrain, with numerous sloughs like Potato Slough, Criminal Slough, and Whisky Slough weaving between major landmasses such as Mandeville Island and Venice Island. Engineers of the era utilized a network of pumping plants to maintain the viability of the Franks Tract and Webb Tract, revealing the ongoing struggle to master the delta's complex hydrology before many modern flood control measures were established.
