Plum Island is an island in Lake Michigan in the southern part of the town of Washington in Door County, off the tip of the Door Peninsula in the U.S. state of Wisconsin.[1] The uninhabited island has a land area of 1.179 square kilometres (0.455 sq mi) or 117.87 hectares (291.3 acres). Carp Lake is located on the northwestern side. During years when Lake Michigan's water levels are high, it is a lagoon of Lake Michigan, but it gets cut off as a separate lake during low-water years.[2]
The island is a bird sanctuary under control of the United States Fish and Wildlife Service and part of the Green Bay National Wildlife Refuge since 2007,[3] and is open to the public for recreational purposes.[4] The island also holds the unmanned Plum Island Range Lights and now-closed Plum Island Lifesaving Station.
