Lake Oahe dominates this mid-1980s landscape, its sprawling waters filling the Missouri River valley and creating a complex shoreline of deep inlets like Buffalo Bay and Swift Bird Bay. The map captures the transition of the Missouri into a massive reservoir system, affecting the geography of the Standing Rock Indian Reservation and Cheyenne River Indian Reservation. High ground is defined by distinctive landmarks such as Dog Butte and Laundreaux Butte, while the drainage of the Moreau River and Little Moreau River snakes through the western plains.
