Twenty five miles of river, 3,200 acres of water and 9,200 acres of forest await you on the Peshtigo River State Forest, the natural gem of Marinette County. Established in 2001, the property is Wisconsins newest state forest. It was purchased from the Wisconsin Public Service Corporation and includes The Peshtigo River which is a 136 mile long (219 km) tributary of Green Bay in the U.S. state of Wisconsin. A section of whitewater on the river called the Roaring Rapids is well known in the region. Further downstream there are two dams known as Caldron Falls Dam and High Falls Dam. The Potato Rapids Flowage, located 20 miles southeast of the main forest.
