Forest City serves as the primary hub in this agricultural region of Central Illinois, where the landscape is defined by an extensive network of drainage infrastructure designed to manage the flat, low-lying terrain. The map reveals the critical importance of water management through named channels like Quiver Ditch, Roos Ditch, and Allens Grove Ditch, which crisscross the rural townships of Manito, Sherman, and Pennsylvania.
