Storsjöodjuret (Swedish pronunciation: [ˈstuːʂøːuˈjʉːrɛ], literally "The Great-Lake Monster") is a lake monster reported to live in the 300-foot-deep (91 m) lake Storsjön in Jämtland in the middle of Sweden. The lake monster was first reported in 1635 and is the only one of its kind in Sweden. When the only city located by Storsjön, Östersund, celebrated its 200 year anniversary in 1986 Storsjöodjuret along with its offspring and nest became protected by law, a law which was revoked in 2005.
