2015 Map of Lemmon Lake

About this map

Grand River National Grassland dominates this section of the Great Plains in Corson County, where the sprawling prairie meets a complex network of seasonal drainages. The landscape is defined by the winding course of the Grand River in the south and the namesake Lemmon Lake to the east. A grid of section roads, including Airport Rd, Lemmon Lake Rd, and Dewitt Rd, provides access across the open range and connects various parcels of public and private land. Numerous creeks like Thunder Hawk Cr, E Thunder Hawk Cr, and Dog Tooth Cr carve subtle coulees through the high plains, illustrating the hydrology of this northern South Dakota district before it reaches the Missouri River watershed.
