2012 Map of Moreau NW

About this map

Lake Oahe dominates the northern and southern margins of this Corson County landscape, illustrating the vast reach of the Missouri River's reservoir system into the drainage basins of north-central South Dakota. This 2012 survey captures a transition zone where the high prairie is dissected by numerous seasonal watercourses, including Timber Cr and Le Beau Cr, which carve through the terrain toward the main body of the lake. The road network is sparse, defined primarily by local routes like Co HWY-14 and Co HWY-12, reflecting the low-density settlement pattern characteristic of the region. The map provides a clear view of how topographic features such as Chicken Cr and Deadman Cr influence the placement of rural infrastructure and agricultural boundaries in this expansive riverine environment.
