The Rock River carves a winding path through this northern Illinois and southern Wisconsin borderland, serving as the central geographic feature for the growing communities of South Beloit, Rockton, and Roscoe. The river's confluence with the Pecatonica River and the smaller Turtle Creek defines the local hydrology, creating landmarks like Boney Island and supporting newer residential developments such as Riverdale and South Bluff Homes.
