2015 Map of De Grey

About this map

De Grey sits on the northern banks of the Missouri River in this 2015 study, overlooking the expansive waters of Lake Sharpe. The landscape is defined by the sharp transition from the elevated plains of central South Dakota down to the river valley, where drainage patterns like Chapelle Cr and South Chapelle Creek carve through the terrain. This map shows the rural infrastructure north of the river, with a grid of section roads including Dunbar Road and Chapelle Road connecting the high country to the riverfront. The inclusion of the Hughes and Stanley county boundary line as it follows the river channel provides a clear look at the political geography of this reach of the Missouri. Further south, SD-1806 follows the shoreline, serving as the primary corridor through this sparsely populated riverine environment.
