Welcome to Rose Atoll National Wildlife Refuge
Rose Atoll is nearly square, with the ocean-side slopes about 1 mile in length. It is one of the smallest atolls in the world, consisting of two low sandy islets, Rose and Sand. Each is located on a coralline algal reef rim enclosing a lagoon. A single, natural pass with a minimum depth of 8 to 48 feet deep links the lagoon to the sea. The lagoon is a maximum of 1.2 miles wide and up to about 65 feet deep, and includes 1,575 acres. Rose and Sand Islands cover areas of about 14 and 7 acres respectively. The Refuge includes emergent lands and waters to the extreme low water line of the perimeter reef. Rose Atoll is part of the Territory of American Samoa and was established as a National Wildlife Refuge by cooperative agreement between the Government of American Samoa and the Bureau of Sport Fisheries and Wildlife (a predecessor of the U.S. Fish & Wildlife Service) on August 24, 1973.
