David H. DeJong‘s Diverting the Gila: The Pima Indians and the Florence-Casa Grande Project, 1916–1928, explores the complex web of tension, distrust, and political maneuvering to divide and divert the scarce waters of the Gila River. Residents of Florence, Casa Grande, and the Pima Reservation fought for vital access to water rights. As was often the case in the West, well-heeled, nontribal political interests manipulated the laws at the expense of the Indigenous community.
