Mill Creek feeds the 1,400-acre Cagles Mill Lake, and the beautiful Cataract Falls, inside Lieber State Recreation Area. Consisting of two sets of waterfalls, about one mile apart, on Mill Creek. They are the largest waterfall by volume in the state and resulted from two pre-glacial bedrock ridges buried beneath ancient lake sediments of the Illinoisan glacial period.
Fast-forward a couple million years, and in the 1700s the area was populated by Native Americans of the Miami, Shawnee and Potawatomi bands.
