Portage River (Jackson County, Michigan)

The Portage River in Jackson County, Michigan, is a small river that is part of the Grand River watershed. It is primarily located within the eastern portion of Jackson County. The river's source is a chain of lakes and wetlands, including Portage Lake, from which it derives its name.

The Portage River generally flows north and east, eventually emptying into the Grand River. The river's course meanders through a landscape consisting of agricultural land, forested areas, and residential developments. Its flow rate is typically moderate, influenced by rainfall and seasonal variations.

The river's water quality is impacted by agricultural runoff and residential development, issues common to many waterways in southern Michigan. Efforts are underway by local conservation groups and government agencies to monitor and improve water quality through best management practices in agriculture and stormwater management initiatives.
