The Gila River valley in the early 1960s was a corridor of agricultural intensity and early Arizona settlement, anchored by the Southern Pacific railroad. Along this route, towns like Thatcher, Pima, and Central are surrounded by a complex network of irrigation infrastructure, including the Smithville Canal, Dodge Canal, and Union Canal. These waterways supported the local economy, evidenced by the Cotton Gin at Cork and various pumping stations that drew from the river and artesian wells.
