Maumee AOC

 

The Maumee Area of Concern, located in northwest Ohio, encompasses a portion of the Lower Maumee River watershed that includes almost 23 miles of the mainstem of the Maumee River, as well as 11 additional independent waterways that flow into the Maumee River, Maumee Bay or Lake Erie. The AOC includes 787 square miles of watersheds, 45 miles of Lake Erie shoreline and over 1,930 miles of streams. 

The Maumee Area of Concern is among the largest of Great Lakes Areas of Concern by area. The past industrial uses of the river resulted in conditions and areas that need to be remediated and restored for sediment contamination, degraded fish and wildlife health and impaired recreational uses within the AOC. 

The Maumee Area of Concern has ten of 14 beneficial use impairments to address as it moved towards delisting. Through the partnership of the local Advisory Committee and numerous local, state and federal partners, the Maumee AOC has established management actions to address the remaining BUIs and have many projects underway. A notable achievement is the completion of the Ottawa River sediment remediation project in 2010. As of December 2020, the Maumee AOC had identified all of its Management Actions and removed one of its ten BUIs.
