Lake Oahe dominates the western landscape of this Missouri River region, creating a distinctive shoreline where the water meets the prairie drainages. The settlement of Cow Creek serves as a focal point near the southern reaches of the map, situated where several creeks converge. This area is defined by its transition from high plains to the inundated river valley, with numerous small waterways such as Okobojo Cr and Plum Cr carving through the terrain towards the reservoir.
