Coffeen Lake dominates this central Illinois landscape, its dendritic shoreline created by the flooding of East Fork and its tributaries including McDavid Branch. In the mid-1970s, the area reflects a transition toward heavy industrial utility, marked by the presence of a powerplant with a Powerplant Stack, Ash Disposal Ponds, and an extensive conveyor system. This energy infrastructure sits alongside established agricultural and extraction sites such as several Oil Wells and a claypit.
