Savanna Portage State Park is a state park of Minnesota, USA, established in 1961 to preserve the historic Savanna Portage, a difficult 6-mile (9.7 km) trail connecting the watersheds of the Mississippi River and Lake Superior. The park contains a drainage divide separating the West Savanna River, which drains to the Mississippi River and the Gulf of Mexico, from the East Savanna River, which flows in an opposite direction to the Saint Louis River, Lake Superior and the Great Lakes, and the Saint Lawrence River to the Atlantic Ocean.
