About this map

Lake Oahe dominates the northern landscape of this 1968 survey, showing the reservoir at its normal pool elevation of 1608 feet. Entirely contained within the Cheyenne River Indian Reservation, the terrain is defined by the winding course of the Moreau River and its numerous tributaries, including Hokshela Creek and No Mouth Cr. The small settlement of Moreau is situated near the riverbanks, anchored by the Ascension Ch, serving as a focal point for the local community during this era.

Evidence of early land use and resource extraction appears through several Gravel Pits scattered across the uplands. The complex drainage network of the East Fork and West Fork of Beaver Creek illustrates the intricate topography of the Missouri River breaks, where the land drops toward the flooded valley floor. This map captures the region's character shortly after the filling of the Oahe Dam altered the historical river landscape.
