2012 Map of Bouldin Island

About this map

Bouldin Island and the surrounding labyrinth of the California Delta are defined by a complex network of levees, reclaimed land, and waterways in this early 21st-century survey. The landscape is a patchwork of large islands such as Venice Island and Mandeville Island, separated by managed channels including Venice Cut and Holland Cut. This geography illustrates the intensive water management required to maintain these agricultural tracts below the water level of the San Joaquin River and Mokelumne River. Small hubs of activity like Central Landing and the Venice Ferry crossing provide the primary points of access in an area otherwise dominated by field patterns and sloughs. Named reaches like Webb Reach and Mandeville Reach highlight the importance of these waterways as navigable corridors for the region's river-based transport and irrigation systems.
