About this map

Missouri River waters dominate this central South Dakota landscape as they pool into Lake Oahe. The 1968 survey reveals a massive hydrological transformation, where the rising reservoir meets the rugged breaklands of Walworth, Dewey, and Corson counties. The map is defined by the convergence of several major land jurisdictions, including the Standing Rock Indian Reservation and the Cheyenne River Indian Reservation.

Along the western shore, the small settlement of Ridgeland sits near the headwaters of Le Compte Creek. Tributaries like Blue Blanket Creek and Little Bear Creek cut through the high plains to meet the flooded valley. Local industry and recreation are noted through several Gravel Pits and a designated Picnic Area, while red dashed lines indicate the network of fences and field lines that defined the agricultural life of the Missouri breaks before further inundation.
