Geography and Course
The journey of the Pine River begins in Wheatland Township, situated in southeast Mecosta County. From its source, the river follows a winding path through several counties in Michigan's Lower Peninsula.
Initially flowing southeast, the river enters southwest Isabella County before turning south through northeast Montcalm County and Gratiot County. Upon reaching Gratiot County, the river shifts its direction toward the northeast, passing through the cities of Alma and St. Louis.
The river eventually enters Midland County, where it reaches its mouth. It joins the Chippewa River approximately two miles before the Chippewa itself merges with the Tittabawassee River on the west side of the city of Midland.

Environmental History
The Pine River has faced significant environmental challenges due to industrial activity. Specifically, the river was contaminated by the Michigan Chemical Corporation, which later became the Velsicol Chemical Corporation, located in St. Louis. Because of this pollution, the waterway has been the focus of extensive and ongoing clean-up efforts to restore its ecological health.
