1928 Map of Corcoran

About this map

Agricultural development and water management define the landscape around Corcoran during the mid-1920s. This survey, conducted by S.B.O'Hara, reveals a meticulously gridded interior of the San Joaquin Valley where the Atchison Topeka and Santa Fe railroad cuts a sharp diagonal through a complex web of irrigation infrastructure. The map documents the northern reaches of the former Tulare Lake bed, evidenced by the Kings Lake Shore and the Kings Lake Tulare Water Co Canal, indicating how local water resources were diverted to support burgeoning settlements like South Corcoran and Turnbull. Small rural social centers are visible at Riverdale School and Tenseure School, while the course of the Tule River and various branches of Cross Creek reveal the natural drainage patterns that once dominated this region before extensive canalization. The transition from natural waterways to an engineered environment is clear through the many named ditches such as Sweet Canal and the West Corcoran Ditch.
