Kalamazoo River

The Kalamazoo River is a river in the U.S. state of Michigan. The river is 130 miles long from the junction of its North and South branches to its mouth at Lake Michigan, with a total length extending to 178 miles when one includes the South Branch. The river's watershed drains an area of approximately 2,020 square miles and drains portions of eight counties in southwest Michigan: Allegan, Barry, Eaton, Van Buren, Kalamazoo, Calhoun, Jackson, Hillsdale, Kent and Ottawa. The river has a median flow of 1,863 cubic feet per second at New Richmond, upstream from its mouth at Saugatuck.

The North and South Branches of the Kalamazoo River originate within a few miles of each other. The South Branch begins near North Adams in Moscow Township in northeastern Hillsdale County and flows north and west through Homer before joining the North Branch at the forks of the Kalamazoo in Albion. The North Branch begins near Farewell and Pine Hills lakes in southern Jackson County and flows north and west through Concord before reaching Albion in Calhoun County. It then flows through Kalamazoo and Allegan counties.
