1929 Map of Porterville

About this map

Agricultural development in the San Joaquin Valley is defined here by an intricate web of irrigation works branching off the Tule River. The landscape is etched with named waterways like Porter Slough and Dead Horse Slough, alongside a systematic grid of ditches including the Hunsaker Ditch, Stockton Ditch, and Fine Ditch. These water systems supported a growing network of small rural school districts, with sites like Welcome Sch, Alta Robles Sch, and Olive Sch serving scattered farmsteads.
