About this map

Lake Oahe dominates this central South Dakota landscape, where the Missouri River's impoundment creates a complex, branching shoreline along the boundary of Dewey Co and Stanley County. The terrain is defined by a series of drainages including Fishgut Cr, Sage Cr, and Paradis Cr, which carve through the plains toward the reservoir. These seasonal watercourses dictate the local geography, leading into distinctive landforms such as Fine Weather Draw. In the southern reaches, the elevation levels out into broad areas known as Kid Rich Flats and Little Flats. Transportation is sparse, relying on Bureau of Indian Affairs routes like Bia-802 and Bia-803, reflecting the rural character of this region within the Cheyenne River Reservation area during the early twenty-first century.
