Swan River (Michigan)
 The Swan River is a 17.3-mile-long (27.8 km) river in Presque Isle County Michigan. It originates in a swamp south of Belknap and east of Hawks. It flows generally northeast between the Trout River and Little Trout River watersheds. The river enters the small Swan Lake just southeast of Calcite limestone quarry before reaching its mouth in Lake Huron in a small bay between Adams Points and Quarry Point. The river is not navigable but provides a salmon habitat.
