USGS Topo · Published 1980About this map
Clinton Lake dominates this central Illinois landscape, its expansive waters and designated Heat Sink serving the massive Powerplant complex situated at the junction of Harp and De Witt townships. This late-1970s survey captures the region during a period of significant industrial and hydrological transformation, where the managed waters of the North Fork Salt Creek meet modern energy infrastructure.
