1989 Map of San Carlos Reservoir

About this map

San Carlos Reservoir dominates the landscape of the San Carlos Indian Reservation in this detailed survey of the high desert terrain. The impounded waters of the Gila River reach into various canyons and draws, such as Cottonwood Canyon and Chittakow Draw, while the Coolidge Dam Road traces the southern rim. Of particular interest to historians is the Old Indian Treaty Boundary cutting across the southwestern corner near Mount Geronimo and Rockhouse Mountain. The map records essential water sources in this arid environment, including Wire Corral Spring, Cottonwood Spring, and several named wells like Starlight Well and Gunter Well. Landmarks like Old San Carlos Point and Flatiron Mesa provide topographical orientation for the desert landscape before the 1990s.
