About this map

Agricultural development in the Central Valley is defined by an intricate network of irrigation infrastructure in this late 1920s survey. The landscape is dominated by a grid of canals and ditches designed to manage water flow across the flat terrain, including the Last Chance Ditch, New Deal Canal, and Chamberlain Ditch. These man-made waterways interact with natural drainage patterns like Mussel Slough and Lone Oak Slough, reflecting the massive engineering efforts required to sustain farming in Kings County.
