2012 Map of Holt

About this map

The San Joaquin River and Middle River wind through the complex delta lands west of Stockton, defining a landscape of low-lying islands and fertile tracts. This 2012 survey reveals the intricate network of waterways and levees essential to the region's agricultural character, featuring prominent landmarks like Vulcan Island and Acker Island. Local transport and commerce are anchored by the settlement of Holt and various water-access points such as Blackslough Landing and Eldorado Landing. The engineering of the Mokelumne Aqueduct cuts a straight path across the terrain, contrasting with the meandering natural sloughs. Genealogists and historians can trace the rural infrastructure of San Joaquin County, from the McDonald Island Ferry to small railroad-aligned sites like Gillis and Trull, which reflect the area's long-standing reliance on river-and-rail connectivity.
