Class I Flatrock River, IN

The Flatrock River originates in the rich farmland of Henry County and flows approximately eighty-eight miles before joining the Driftwood River to form the East Fork of White River at Columbus, Indiana. Once lined with mills producing essential materials for Hoosier settlers, the river now flows quietly, primarily through farmland with an almost constant narrow wooded strip paralleling the river (Indiana DNR Canoeing Guide).
