LaPlace and Lake City anchor this central Illinois landscape, where the flat agricultural plains of Moultrie and Piatt Counties are dissected by a network of drainage infrastructure and small waterways. The upper reaches of the Kaskaskia River wind through the eastern half of the quadrangle, joined by tributaries such as Stringtown Br and several man-made channels including Ditch Number 3 and Hammond Mutual Ditch. These features reflect the 19th and 20th-century efforts to manage the prairie’s hydrology for productive farming.
