The Macomb region in West Central Illinois is defined by the significant confluence of river systems and the late-century expansion of conservation lands. This 1989 U.S. Geological Survey compilation reveals a complex network of wetlands and backwaters along the Illinois River, where the Sanganois State Conservation Area and Chautauqua National Wildlife Refuge preserve vast stretches of aquatic habitat. The mapping of Lake Chautauqua and Anderson Lake highlights a landscape where human utility and natural preservation coexist, bounded by the active industrial corridors of the Burlington Northern RR.
