Sheboygan River

It is about 81 mi (130 km) long[1] and enters the lake at the city of Sheboygan.Along its course the river flows past the village of St.Cloud, the cities of Kiel and Sheboygan Falls, the village of Kohler and the city of Sheboygan, where it enters Lake Michigan.Because of past heavy manufacturing on the eastern portion of the river from companies such as Tecumseh Products in Sheboygan Falls, Kohler Company, and the predecessor companies of Wisconsin Public Service near Sheboygan's downtown, the riverbed has a high concentration of PCBs and other chemicals which make any form of swimming in the river east of Sheboygan Falls' western limits impossible, thus it has been a working Superfund site from the Sheboygan Falls Dam (approximately at Monroe Street in that city eastward) since June 1986.[4] Cautions on fishing and warnings about consumption of fish in the Sheboygan River east of the Falls Dam are also enforced by the Wisconsin Department of Natural Resources, and posted at all boat launches along Sheboygan's river frontage.
