The Missouri River defines the central geography of this landscape, where the rising waters of Lake Sakakawea have created a complex shoreline of deep inlets and peninsulas. Several prominent water bodies, including Douglas Creek Bay, Berthold Bay, and Beulah Bay, demonstrate how the inundated valley has transformed the regional terrain. The map records the interface between McLean and Mercer Counties along the river's path, showing the submerged former course of the Missouri as it winds through the reservoir.
