About this map

Missouri River waters dominate this landscape, where the wide expanse of Lake Oahe defines the contemporary geography of the border between Dewey and Potter counties. The map illustrates a complex shoreline of inlets and points, most notably the prominent Dolphus Peninsula which extends into the reservoir from the east. This modern survey reflects the significant transformation of the Missouri valley since the mid-20th century dam projects, showing how the rising waters created features like Swift Bird Bay while submerging the original river banks. Land navigation is traced through local routes like Swift Bird and W Whitlock Rd, alongside the historical alignment of Old US Hwy-212. The presence of the Louis Badger Trl suggests the area's continued importance for local transit and shoreline access within this rural South Dakota corridor.
