2015 Map of Clear Lake North

About this map

Coteau des Prairies defines the rolling topography of this Deuel County landscape, where glacial depressions have formed a dense cluster of water bodies. The settlement of Altamont sits in the northern half of the quadrangle, while the city of Clear Lake anchors the southern edge near its namesake Clear Lake. This 2015 survey illustrates a rural South Dakota environment shaped by modern infrastructure, including the Clear Lake Municipal Airport and a strictly defined grid of range roads like 475th Ave and 180th St. Water is the dominant geographic feature, ranging from the large expanse of Lake Alice in the northeast to the interconnected chain of North Coteau Lake, East Coteau Lake, and South Coteau Lake in the west. These lakes, alongside smaller basins like Ketchum Lake and Lake Sutton, suggest a landscape where land use is dictated by the natural drainage of Monighan Cr.
