River in Michigan

The river is an important shipping route for Mid Michigan, passing through the cities of Saginaw and Bay City. It is one of Michigan's few inland navigable rivers.

From the 18th century, fur traders and trappers rendezvoused at a post at the mouth or traveled along the river and its tributaries to trade with the Ojibwe tribes of the region for European and American manufactured goods. As towns developed along the river, it supported additional travel inland, as well as powering the operation of sawmills and later factories. The first lighthouse was completed in 1841, and a pair of lighthouses were built in range configuration in 1876. They were converted to electricity in 1915.

According to Saginaw Future, the river carries 4.6 million tons of commerce annually. Other industries developed, with both General Motors and Dow Chemical Company basing major operations from the early 20th century at sites along the river.
