Pecatonica River

The Pecatonica river flows down from Wisconsin, through Freeport, and then into the Rock River. It is a very remote river, primarily surrounded by woods and farmland. There are few towns neighboring the river.

The Pecatonica river flows about 2 MPH, with a gradient of less than 1 foot per mile.
