An $80 million river dredging, and habitat reclamation project was completed in 2013. A dredging, completed in 2013, cleared 400,000 cubic yards of sentiment including deepening the navigational channel and port to 15 feet.
The Sheboygan River was originally contaminated due to PCB use at a die-cast plant further up river. The lower 14 miles of the Sheboygan River has been cleared of PCB pollution. In addition, 34 acres along the river shore were restored to their natural habitation.
The Sheboygan River is still labeled a superfund site; however, has gone from an area of concern to an area in recovery.
