About this map

Turner Island and the surrounding Merced County wetlands dominate this landscape, characterized by an intricate network of irrigation and flood control systems. The San Joaquin River meanders through the southern half of the quadrangle, flanked by seasonal watercourses like Salt Slough and Poso Slough. Large-scale ranching operations are the primary footprint of human activity, including the sprawling Turner Ranch, McNamara Ranch, and Crane Ranch.

A complex hydraulic infrastructure supports this agricultural region, featuring the Mariposa Bypass, the East Side Canal, and numerous specialized channels such as Loop Ditch Number One and the Pick Anderson Drain. The eastern edge includes a portion of the Merced National Wildlife Refuge, where the Mariposa Slough provides a natural contrast to the engineered grid of the surrounding valley floor.
