About this map

The agricultural heart of the San Joaquin Valley is meticulously detailed in this survey by S.B.O'Hara, showing the region in the late 1920s. Centered on Corcoran, the map reveals a landscape defined by an intensive irrigation network, featuring the Sweet Canal, Dairy Avenue Canal, and numerous ditches like the West Corcoran Ditch. This infrastructure highlights the transformation of the arid basin into a productive farming hub. The Atchison Topeka and Santa Fe railroad cuts diagonally across the grid, serving as the primary artery for moving the valley's produce.
