2012 Map of Lake De Smet East

About this map

Lake De Smet and its surrounding water management systems anchor this high-plains landscape in Johnson County. The map details an extensive network of irrigation and drainage features, including the Lake Desmet Canal and the Redman Ditch, which trace the movement of water across the prairie to support local agriculture. Prominent landmarks such as Seney Point jut into the lake, while the Moore Reservoir provides further storage along Boxelder Creek. To the south, the Johnson County Airport serves as a modern transportation hub alongside Interstate 90. The drainage patterns of Clear Creek, Rock Creek, and Sand Creek reveal the natural topography that dictated early ranching routes, many of which are now preserved as rural roads like M&M Ranch Rd and Stage Trail Rd.
