2012 Map of Wakpala SE

About this map

Lake Oahe dominates the eastern and northern reaches of this landscape, its complex, finger-like shoreline defining the boundary of Corson County. This 2012 survey captures the hydrology of the Missouri River reservoir system, where the rising waters have submerged the lower reaches of major tributaries. Both Snake Creek and Claymore Creek are shown as they transition from narrow prairie streams into broad, flooded inlets of the main reservoir. The map documents a sparsely populated region of South Dakota characterized by high-elevation contours and a minimal road network, reflecting the geographic isolation and specialized land use common to the lands surrounding the Oahe Dam project. Small seasonal watercourses like Snake Creek feed into the larger system, highlighting the drainage patterns of the northern plains.
