The Connecticut River Watershed Partnership Act establishes a comprehensive, nonregulatory program aimed at restoring and protecting the vital 5-State Connecticut River Watershed region. Within 180 days of enactment, the Secretary of the Interior, acting through the U.S. Fish and Wildlife Service, must create this program to identify, prioritize, and implement restoration and protection activities through an inclusive, Watershed-wide strategy. The program's duties involve extensive consultation with Federal agencies, State Governors, Tribal governments, and various regional and nonprofit organizations, including stakeholders from environmental justice communities . Its core purposes include coordinating efforts among diverse entities, restoring fish and wildlife populations, improving water quality, and advancing nature-based solutions for community resilience. Key objectives also encompass supporting farmland conservation, promoting traditional Tribal ecological knowledge, enhancing public access to open spaces, and increasing scientific capacity for planning and research. The program seeks to engage the public, particularly environmental justice communities, through outreach and education to foster support for coordinated restoration efforts. In parallel, the bill establishes a voluntary Connecticut River Watershed Partnership grant program to provide competitive matching grants to eligible entities, including State, Tribal, and local governments, nonprofits, and higher education institutions. These grants will fund projects that align with the program's restoration and protection goals, with criteria ensuring equitable fund distribution. A significant provision of the grant program is its tiered cost-sharing structure: while the Federal share is generally 75%, projects serving environmental justice communities can receive a 90% Federal share, which may be waived to 100% if the recipient faces financial hardship. The Secretary may contract with organizations like the National Fish and Wildlife Foundation to administer these grants, and the bill authorizes appropriations for fiscal years 2026 through 2030, with at least 75% dedicated to the grant program and technical assistance.
