The Manistique River is a 71.2-mile-long (114.6 km)river in the U.S. state of Michigan that winds southward through the central Upper Peninsula from its headwaters near Lake Superior to its mouth in Lake Michigan. It drains approximately 1,461 square miles (3,780 km2) of the Upper Peninsula, including most of Schoolcraft County and small portions of Alger County, Delta County, Luce County, and Mackinac County. The river rises at the outlet of Manistique Lake in the southwest corner of Luce County, and after flowing through the Seney National Wildlife Refuge, empties into Lake Michigan at Manistique, Michigan. M-77, a north-south highway, serves much of the Manistique River's drainage and crosses the river and its tributaries several times.
The drainage of the Manistique River is very flat and sandy. The river is not characterized by rapids or waterfalls. Instead, it wriggles along an alluvial bed of sand and silt eroded and redeposited by the river itself. The Manistique River's drainage was one of the last zones in Michigan to be clear cut, with old-growth timber being felled as late as the 1910s. The watershed was then abandoned or reverted to state and federal ownership. As of 2007[update], 93% of the drainage was forested, largely with second-growth trees such as aspen and birch. More than one-half, 58%, of the drainage was owned by the federal government or the state of Michigan. Governmental ownership units included the Seney National Wildlife Refuge, Hiawatha National Forest, and Lake Superior State Forest.
