Lake Oahe dominates the central landscape of this South Dakota region, where the boundaries of Corson, Dewey, and Walworth counties meet along the Missouri River reservoir. The terrain reflects the complex drainage patterns of the northern plains, defined by the winding paths of Le Compte Cr and Little Bear Cr as they cut through the upland breaks toward the water.
