About Clinton River AOC

The Clinton River, located just north of Detroit in southeastern Michigan, flows 80 miles from its source to Lake St. Clair near the city of Mt. Clemens.  It became an Area of Concern under the Great Lakes Water Quality Agreement of 1987.

The area was considered highly degraded because of:

  • conventional pollutants including high fecal coliform bacteria and nutrients
  • high total dissolved solids
  • sediment contamination caused by heavy metals, PCBs, oil and grease
  • impacted biota

The areas of concern include the entire Clinton River watershed as well as a portion of Lake St. Clair immediately downstream.
