About

The Iroquois is a slow, winding, lazy river, which in large part was by-passed by the settlers and developers who pushed progress into Indiana. The muddy waters flow approximately 94 miles through rich farmland which was once swampland and was untouched by pioneers until as late as 1850. Today the area has been extensively drained and the Iroquois flows through prairies and narrow woodlands passing a few cabins as it twists westward into Illinois. (Indiana DNR Canoeing Guide)
