2017 Map of No Heart Creek SE

About this map

Lake Oahe dominates this landscape along the border of Dewey and Sully counties, where the modern impoundment of the Missouri River has fundamentally altered the terrain. The shoreline is defined by deeply recessed inlets like Willow Creek Bay and smaller drainage features such as Fairbanks Cr and Splits Cr, which carve into the surrounding bluffs. The map reflects a sparsely populated area primarily structured by the Public Land Survey System, with township lines like t11n r29e and t10n r30e providing the primary geographic orientation. Away from the water, the terrain transitions into high-plains topography, accessible by limited infrastructure like 182nd St. This survey illustrates the relationship between the vast reservoir system and the remote rural townships that border it in the early twenty-first century.
