1978 Map of Bouldin Island

USGS Topo · Published 1993

About this map

The Mokelumne River and San Joaquin River converge in this intricate delta landscape, where land is defined by a complex network of sloughs, cuts, and reaches. This 1978 survey highlights the reclaimed island tracts that form the heart of the California Delta, including Bouldin Island, Webb Tract, and Mandeville Island. The reliance on water management is evident through numerous Pumping Stations and Tide Gages scattered across the low-lying terrain.
