About this map

Grand River meanders across this South Dakota landscape, defining the topography of the Rock Creek District. This 2012 survey illustrates the high-prairie hydrology of Corson County, where numerous seasonal and permanent waterways converge. The river receives significant flow from southern tributaries including Firesteel Cr, while northern drainages like Hump Cr and White Shirt Cr carve distinct paths through the northern elevations. To the west, Soldier Cr adds to the complex drainage network that has historically shaped the agricultural and ranching potential of this region. The map reveals the relationship between the natural watercourse of the Grand River and the local road infrastructure that navigates these prairie creek beds.
