About this map

The Sangamon River defines the southern boundary of this central Illinois landscape, where it meets the Mason Co and Menard Co line. North of the river, a sophisticated network of agricultural drainage channels, such as Biggs Ditch, Newton Ditch, and Tomlin Ditch, has been engineered to manage the low-lying prairie terrain. These artificial waterways cut through a region marked by natural features like Perry Slough and Wash Lake Slough, illustrating the long-term human effort to reclaim the land for farming.
