1986 Map of Onida

About this map

Lake Oahe dominates this central South Dakota landscape, where the waters of the Missouri River meet the Cheyenne River. The western portion of the sheet is defined by the Cheyenne River Indian Reservation Boundary, while the eastern plains are characterized by a grid-like organization of agricultural land and small rail-centered settlements. The Chicago and North Western railroad provides a vital lifeline to the town of Onida, the regional hub, and nearby Agar. Away from the water, the terrain includes distinctive landmarks such as Mission Ridge and Medicine Butte. Multiple recreation and game production sites, including the Sutton State Game Production Area and Okobojo Creek Recreation Area, line the irregular shores of the lake, illustrating the 1980s-era emphasis on public land management and water-based geography.
