2021 Map of Madison NW

About this map

Lake Badus and the surrounding glacial prairie of the Coteau des Prairies plateau define the landscape of northwestern Lake County in this 2021 survey. The region is characterized by a high concentration of wetlands and water bodies, including Spring Lake in the north and the expansive Dry Lake to the south. Historically, the area near Lake Badus was a center for Swiss-German settlement, a heritage reflected by the location of Saint Ann's Cem along its eastern shore. Agricultural life is structured by a rigorous grid of section roads such as 453rd Ave and Co Hwy 10, while Battle Cr provides the primary natural drainage through this upland terrain. The map also delineates the shared borders with Kingsbury and Brookings counties, illustrating the rural connectivity and land management patterns of contemporary South Dakota.
