2017 Map of No Heart Creek SW

About this map

Lake Oahe dominates the landscape of this 2017 topographic study, marking the winding course of the Missouri River as it carves through the plains of South Dakota. The prominent peninsula known as Little Bend creates a massive loop in the waterway, illustrating the dramatic hydrography that defines the borders of Dewey, Stanley, and Sully Counties. This modern survey, compiled from National Hydrography Dataset and NAIP imagery, focuses on the vast water-to-land interface of the reservoir system. The lack of roads or settlements within this quadrant highlights the transition of this river valley into a managed waterway, where the intricate shoreline of Lake Oahe follows the submerged contours of the old river breaks.
