Saginaw, river, 22 mi (35 km) long, formed by the confluence of eight branches, SE Mich. The river drains a large area of lower Michigan and flows into Saginaw Bay (c.60 mi/100 km long and 15–25 mi/24–40 km wide), an arm of Lake Huron. Bay City, a port, is located at the bayhead near the river's mouth, and Saginaw is located upstream. Coal, pig iron, salt, and oil are transported on the river.
