This bill, titled the Regional Great Lakes Partnership Act of 2026, seeks to formally recognize the Great Lakes Commission as a Regional Great Lakes Partnership . It achieves this by amending a specific section of the James M. Inhofe National Defense Authorization Act for Fiscal Year 2023. The amendment adds the Great Lakes Commission to a list of designated partnerships, thereby integrating it into a broader framework for regional collaboration. The Commission, established under the Great Lakes Basin Compact, includes the states of Illinois, Indiana, Michigan, Minnesota, Wisconsin, New York, Ohio, and Pennsylvania. This designation is intended to strengthen the Commission's role and capabilities in addressing issues pertinent to the Great Lakes region.
