Access: Gray area.
Wisconsin holds the bed of the Great Lakes below the ordinary high-water mark in public trust, so removing historic artifacts from the submerged lakebed is restricted and generally not permitted without state authorization; the townsite banks, beaches above the line, and uplands are usually privately owned and require the landowner's permission; state law also protects archaeological sites and unmarked burials.
