2018 Map of Turner Ranch

About this map

Turner Island and the surrounding basin of the San Joaquin Valley define this landscape, where complex water management systems dominate the terrain. A dense network of man-made and natural waterways, including the San Joaquin River, Salt Slough, and Mariposa Slough, illustrates the intricate irrigation and drainage efforts required to support the local agricultural economy. Features like the Loop Ditch Number One, Siphon Ditch, and Delta Canal crisscross the region, serving the eponymous Turner Ranch and neighboring parcels. To the east, the Merced National Wildlife Refuge provides a significant preserved wetland environment amidst the grid of rural roads such as Sandy Mush Rd and Nickel Rd. This survey captures the specialized infrastructure of the Central Valley just before the 2020s, showing how local drainage like the Pick Anderson Drain and various lateral canals manage the river's flow through the valley floor.
