About this map

Agricultural development and water management define this portion of Merced County within the San Joaquin De Santa Rita land grant. The landscape is dominated by an intricate network of irrigation and drainage infrastructure, featuring the San Joaquin River and Salt Slough alongside numerous man-made channels like the Miller Canal, Poso Canal, and Orchard Ditch. These waterways supported a cluster of significant ranching operations and recreational grounds in the mid-20th century.
