About this map

Lake Oahe and the Missouri River dominate this modern topographic view of the South Dakota landscape, where the borders of Walworth, Corson, and Dewey counties converge. The terrain is defined by the winding course of the Missouri, which serves as a major geographical divider between the high plains and the expansive waters of the reservoir. The drainage patterns of the region are clearly marked by Little Bear Creek and Le Compte Creek, which feed into the main river system through eroded breaks in the shoreline. Modern infrastructure is limited to rural routes such as Walth Bay Road and Riverview Drive, which provide access to the waterfront. This map provides a clear record of the current shoreline and rural road network in a sparsely populated section of the state.
