National Marine Sanctuary: Wisconsin - Lake Michigan

Wisconsin – Lake Michigan is an 875 square mile area of Lake Michigan with waters extending from Port Washington to Two Rivers. The state of Wisconsin nominated this area as a national marine sanctuary through the Sanctuary Nomination Process with broad community support.

The area encompasses historic shipwrecks of national significance that merit the additional management authority of the National Marine Sanctuaries Act. The nominated area contains an extraordinary collection of 39 known shipwrecks, 15 of which are listed on the National Register of Historic Places.

Fourteen of the known shipwrecks are essentially intact and three vessels possess standing masts – a rarity in the Great Lakes. The area also includes Wisconsin's two oldest known shipwrecks. Archival and archaeological research indicates that the proposed sanctuary also includes 123 reported vessel losses.
