North/central along the Kankakee river near the Indiana border. Way back in the day it used to be the "Grand Kankakee Marsh". It's been mostly drained for nearly a century now but there are still quite a few sloughs and stands of flooded timber throughout the area. Even the drained areas in the flood plain (which is immense) start turning back into marsh pretty quickly after an extended rainfall. There's an interesting/cheesey B list documentary on the area called "The Everglades of the north"
