About Ontonagon River
The Ontonagon River is a river flowing to Lake Superior on the western Upper Peninsula of Michigan in the United States. The main stem of the river is 25 miles long and is formed by a confluence of several longer branches, portions of which have been collectively designated as a National Wild and Scenic River.
