Great Lakes Gateways Network Act of 2025

The Great Lakes Gateways Network Act of 2025 creates a coordinated network of sites across the Great Lakes region to conserve, restore, and interpret natural, historical, and cultural resources. It authorizes the Secretary of the Interior (with EPA collaboration) to provide technical and financial assistance for linking these sites - such as parks, historic ports, and cultural landmarks - with trails, water routes, and educational connections. The bill establishes a grants program offering up to 50% federal funding for conservation projects, requiring non-federal matching funds (including in-kind contributions) and capping administrative costs at 10% of project totals. The program is funded at $6 million annually from 2026 through 2031 for state/local governments, nonprofits, and private groups.
