1968 Map of Fort Yates NE

About this map

Lake Oahe dominates the landscape of this 1960s survey, marking a period of profound transformation along the Missouri River valley. The map documents the vast waters held by the Oahe Dam, with the normal pool elevation of 1608 feet defining a new shoreline across the Standing Rock Indian Reservation. This inundation fundamentally altered the geography of the river bottomlands, once home to traditional settlements and agriculture. In the southern portion of the quadrangle, the Winona Flats remain above the waterline, characterized by scattered Gravel Pits and section-line roads. The upland prairie to the east contains traces of earlier settlement patterns, including the Lutheran Cem and the winding course of Little Beaver Creek. The establishment of the Beaver Creek Public Use Area reflects the shift toward water-based recreation following the river's impoundment.
