About this map

Lake Oahe dominates this late-1960s landscape, representing a significant era of hydrological change in the Missouri River Basin. The reservoir's Normal Pool Elevation 1608 redraws the geography where the Cannonball River meets the Missouri River. Within the Standing Rock Indian Reservation, the settlement of Cannon Ball is detailed with its sewage disposal pond and the Cannon Ball Memorial Congregational Cem nearby.

Evidence of earlier transportation and land use is preserved through an Old Railroad Grade running parallel to the western shoreline. The terrain features distinctive Missouri River breaks, highlighted by landmarks like Coal Butte and Twin Buttes. Conservation efforts are visible at the Sunburst Lake National Wildlife Refuge, while the county boundaries of Morton, Emmons, and Sioux converge within the inundated river valley.
