About this map

The Merced National Wildlife Refuge anchors this section of the San Joaquin Valley, a landscape defined by an intricate network of water management features and natural drainage patterns. The map highlights the agricultural and conservation character of the Central Valley, where natural waterways like Mariposa Slough, Chamberlain Slough, and Sand Slough meander alongside engineered systems such as the Sharon Lateral and Benedict Lateral.

Southwest of the refuge lies Turner Island, surrounded by the split channels of the slough system. The grid of rural roads, including Sandy Mush Rd and Headquarters Rd, reflects the organized land divisions typical of Merced County. This documentation of drainage features, from the Steiner Drain to Lateral Five, illustrates the ongoing effort to balance the hydrological needs of both protected wildlife habitats and the surrounding valley farms.
