History

The border between Wisconsin and Michigan was originally defined as "the most usual ship channel" into Green Bay from Lake Michigan but commercial routes existed both to the north and south of the island which led to a border dispute. In 1936, the U.S. Supreme Court decision Wisconsin v. Michigan found that Plum and three other islands were part of Wisconsin.
