The Huron River is a 14.9-mile-long (24.0 km) waterway in the north central Ohio in the United States. The watershed drains large portions of Erie County and Huron County, the northeast corners of Seneca County and Crawford County, and northern portions of Richland County. The mouth is on Lake Erie at the city of Huron. The main branch of the river is formed when the East and West branches merge near Milan. The East Branch, 31.8 miles (51.2 km) long, rises west of Fitchville and flows west to North Fairfield, where it bends north and flows through Peru and Norwalk before reaching Milan. The West Branch is 54.5 miles (87.7 km) long. It rises about 4 miles (6.4 km) south of Greenwich and four miles east of Shiloh, near the intersection of Gilger Road and Noble Road in northern Richland County's Blooming Grove Township.
