Scott City and Illmo stand as the primary urban centers at the edge of the Big Swamp in this modern topographic record. The landscape is defined by extensive water management systems, including the massive Castor River Diversion Channel and the Dutchtown Ditch, which redirect flow through the Black Land Bottom. These engineering works transformed the alluvial terrain north of the undulating hills that house the rural community of New Hamburg.
