2012 Map of Big Stone Lake SE

About this map

Big Stone Lake dominates the northeastern corner of this Grant County landscape, where the waters are punctuated by Goose Island and Manhattan Island. Along the shoreline, Camp Tepeetonka stands as a focal point for recreation and community gathering. The terrain is defined by its drainage patterns, most notably where the N Fork Whetstone River and S Fork Whetstone River converge to form the main channel of the Whetstone River. This 2012 survey illustrates the modern agricultural grid of the eastern South Dakota plains, with a highly organized network of section-line roads like 480th Ave and 145th St providing access to the expansive farmsteads between the river forks. The map provides a clear view of the hydrological interface between the river system and the glacial lake, highlighting the importance of these water resources to the regional identity.
