2014 Map of Dewey Flat

About this map

San Carlos Reservoir dominates the northern half of this landscape, its waters meeting the western flow of the Gila River. The settlement of Natches sits along the northern shore, while the eponymous Dewey Flat occupies the river terrace to the east. The terrain is defined by a series of deep drainages, including Hackberry Draw and Sycamore Gulch, which cut through the arid uplands south of the water. Infrastructure in this Graham County region is concentrated around Coolidge Dam Rd and various Bureau of Indian Affairs routes like Bia-555. Small water sources such as Sherman Spring are critical markers in this environment, illustrating the sparse but vital locations of surface water away from the primary river system.
