Connecticut River Watershed Partnership Act

This bill establishes the Connecticut River Watershed Partnership program (Section 3) to coordinate restoration and protection efforts across the 5-state watershed (Connecticut, Maine, Massachusetts, New Hampshire, Vermont). It creates a competitive grant program (Section 4) providing up to 90% federal funding for eligible entities - including states, tribes, nonprofits, and local groups - to carry out projects that improve water quality, restore habitats, and support environmental justice communities. The program requires the Secretary of the Interior to collaborate with Tribal governments, state agencies, and conservation organizations to develop a unified strategy. It mandates annual reporting to Congress and prioritizes projects advancing nature-based solutions, public access, and equitable outcomes in communities facing environmental health risks.
