Maumee River Habitat Restoration at Penn 7

Penn 7: The restoration of a former confined disposal facility in the heart of Toledo provides quality habitat for area fish and wildlife and improves water quality.



The 59-acre Penn 7 project site is located in Toledo, Ohio, on the lower Maumee River near its mouth into Lake Erie. The site was previously a confined disposal facility that accepted sediment dredged from the Maumee River shipping channel in the late 1960s-early 1970s. Penn 7 sits along a section of the Maumee River where shorelines are predominantly lined with metal walls and where floodplain wetland habitat is almost non-existent.



Due to the high amount of urban development along the lower Maumee River, much of the original fish and wildlife habitat has been lost. This restoration project will:

  • Provide quality spawning and nursery space for over 40 species of Lake Erie fish;
  • Provide quality habitat for native birds, amphibians, reptiles, mammals, and river bottom communities;
  • Provide important migratory stopover space for many bird species; and
  • Improve water quality and the overall environmental health of this area.



  • Improve and maintain approximately 59 acres of terrestrial and aquatic habitat to address a Beneficial Use Impairment (BUI) in the Maumee Area of Concern through the creation/restoration of:
    • 5 acres of submerged and emergent wetlands
    • 5 acres of coastal wetlands/open water habitat
    • 20+ acres of upland habitat;
  • Reduce suspended sediments/nutrient concentrations of stormwater that flows into the restored habitat to improve water quality; and
  • Control invasive plant species while promoting native species.



  • To connect the upstream portion of the site with the Maumee River, a water control structure will be installed within the existing dike.
  • To allow river water to flow to and through the new wetland habitat, sediment will be excavated and recontoured in the upstream portion of the site.
  • A channel will be excavated to connect the new upstream wetland to the existing downstream embayment where habitat enhancements will be installed.
  • To protect/enhance the embayment, a dike with a water control and fish passage structure will be installed between it and the Maumee River.





This project is funded by a Great Lakes Restoration Initiative award that is supported by the National Oceanic & Atmospheric Administration and the Great Lakes Commission Regional Partnership through a subcontract to the City of Toledo. The engaged project management team also includes Ohio EPA and ODNR Division of Wildlife.

The Maumee AOC Committee works toward fishable and swimmable waters in the Maumee Area of Concern and delisting the beneficial use impairments. The Committee is working towards all major restoration projects being completed by 2025, through collaboration of partners and volunteer opportunities by its facilitating organization, Partners for Clean Streams. The committee is made up of representatives from various organizations, citizens, businesses and non-government agencies to build long term solutions to the area’s water quality issues.
