About this map

Turner Island dominates this section of the Central Valley, where the complex hydrology of the San Joaquin Valley is on full display. The landscape is defined by an intricate network of waterways designed for irrigation and flood management, including the Mariposa Bypass and San Joaquin River. These natural and engineered channels, such as the E Side Canal and Delta Canal, illustrate the region's total conversion into a high-intensity agricultural zone.

Surface drainage is managed through countless named sloughs and ditches, including Salt Slough, Deep Slough, and Sand Slough. Roads like Green House Rd and Dan McNamara Rd follow the rigid grid of section lines, reflecting the structured land divisions of the Public Land Survey System. The presence of features like Loop Ditch Number One and Pick Anderson Drain underscores the vital role of water engineering in maintaining the productivity of this Merced County terrain.
