About Saginaw River and Bay AOC
The Saginaw River and Bay was designated as an Area of Concern under the 1987 Great Lakes Water Quality Agreement. Contaminated sediments, fish consumption advisories, degraded fisheries and loss of significant recreational values are the major reasons for this AOC designation. Saginaw Bay priorities include nonpoint pollution control, wetland and habitat restoration, and remediation of sediment contaminated with dioxin, PCBs and other organics.
The Saginaw Bay area, located in the east central portion of Michigan's Lower Peninsula, is a southwestern extension of Lake Huron. The boundaries of the Area of Concern includes the entire 22-mile length of the Saginaw River and all of Saginaw Bay out into its interface, with open Lake Huron at an imaginary line drawn between Au Sable Point and Point Aux Barques.

The Land Policy Institue participates in several water quality projects, some of which are funded by the Great Lakes Restoration Initiative. They also help local and regional stakeholders adopt new management strategies in the watershed.
MDEQ is primarily responsible for developing the remedial action plan. They also execute many of the restoration projects in the AOC.
The Partnership for Saginaw Bay Wathershed (PSBW) is a voluntary, membership-based coalition of public and non-governmental agencies, organizations and individuals committed to sustaining or restoring the ecology of the Saginaw Bay Watershed. The PSBW promotes comprehensive resource management and educational services by facilitating inter-governmental coordination and public involvement, formulating public policy recommendations, and undertaking various programs and projects to restore, protect and enhance Michigan's largest watershed.
