The Huron River is a 130-mile-long (210 km) river in southeastern Michigan, rising out of the Huron Swamp in Springfield Township in northern Oakland County and flowing into Lake Erie, as it forms the boundary between present-day Wayne and Monroe counties. Thirteen parks, game areas, and recreation areas are associated with the river, which passes through the cities of Dexter, Ann Arbor, Ypsilanti, Belleville, Flat Rock and Rockwood that were developed along its banks.
The Huron River is a typical Southeast Michigan stream; mud banks, slow stream flow and a low gradient define this river. It runs through the following counties, in order from the headwaters to its mouth: Oakland, Livingston, Washtenaw, Wayne, and Monroe. There are 24 major tributaries totaling about 370 miles (600 km) in addition to the mainstream. The Huron River watershed drains 908 square miles (2,350 km). It is the only state-designated Country-Scenic Natural River in southeast Michigan. This includes 27.5 miles (44.3 km) of the mainstream, plus an additional 10.5 miles (16.9 km) of three tributaries.
