About this map

Lake Sakakawea dominates the landscape of this 1960s survey, marking a transformative period for the Missouri River valley along the McLean and Mercer county line. The map captures the expansive waters of Nishu Bay and the shoreline management practices of the era, visible in the Nishu Public Use Area and the Beaver Creek State Game Management Area.

For family historians and local researchers, the presence of the Beaver Creek Cem near the southern shore provides a critical point of reference for pre-inundation geography. The terrain away from the reservoir is defined by drainages like Sixmile Creek and Buffalo Rock Coulee, while industrial activity is noted by a lone Gravel Pit. The map reflects a landscape in transition, balanced between the new reservoir economy and the traditional rural land patterns of central North Dakota.
