The Kankakee River defines the northern reaches of this landscape, marking the border between Jasper and Porter counties. This region is characterized by a complex network of man-made waterways designed to manage the wetlands of the Kankakee Basin, including Bass Ditch, Sands Ditch, and Luken Ditch. These drainage systems reflect a long history of engineering the land for agriculture, turning once-marshy terrain into the productive fields surrounding settlements like San Pierre and Tefft.
