About this map

Lake Oahe Missouri River dominates this landscape on the border of Sioux and Emmons counties, illustrating the controlled inundation of the Missouri River Basin during the late 1960s. The map reveals the expansive Winona Flats along the western shoreline, part of the Standing Rock Indian Reservation. This area shows the impact of mid-century water management on the local terrain, with vast sections of the river valley transformed into a massive reservoir.
