Coteau des Prairies, a vast plateau extending across the eastern Dakotas, defines the rolling topography of this Codington County landscape. The area is characterized by its glacial hydrology, featuring terminal moraine lakes like Cottonwood Lake and the smaller Still Lake to the south. These water bodies are connected to a drainage network that includes the Big Sioux River, Soo Cr, and Mahoney Cr, illustrating the complex prairie pothole region of the Upper Midwest.
