2015 Map of Piyas Lake

About this map

The Coteau des Prairies plateau, a vast glacially-formed upland, dominates the topography of this northeastern South Dakota landscape. Large, irregular water bodies including Piyas Lake and the Buffalo Lakes serve as primary geographical landmarks, with the county line between Marshall Co and Day Co bisecting the central terrain. The map details a strictly organized sectional grid of township roads such as 122nd St and 444th Ave, reflecting the systematic land survey of the Great Plains. Along the southern shores of the lake system, more localized routes like N Lakeview Dr, Chekapa Ln, and Dulyun Rd indicate areas of residential or recreational development near Chekapa Cr. This 2015 survey provides a modern view of the hydrologic and administrative boundaries that define the Enemy Swim District.
