This legislation establishes the Connecticut River Watershed Partnership program, a nonregulatory initiative led by the Secretary of the Interior through the U.S. Fish and Wildlife Service. Its primary purpose is to coordinate and implement comprehensive restoration and protection activities throughout the 5-State Connecticut River Watershed. The program emphasizes collaboration among Federal, Tribal, State, local, and nonprofit entities, including significant consultation with environmental justice communities , to develop a Watershed-wide strategy. Key objectives include restoring fish and wildlife populations, enhancing habitat, improving water quality, and promoting nature-based solutions for resilience. The bill also creates a voluntary Connecticut River Watershed Partnership grant program , offering competitive matching grants to eligible entities such as governments, nonprofits, and higher education institutions. Projects serving environmental justice communities receive a higher federal cost share, up to 90 percent, with a potential waiver to 100 percent. The Secretary may partner with organizations like the National Fish and Wildlife Foundation to administer these grants, with at least 75 percent of appropriated funds dedicated to the grant program and technical assistance. Annual reports on implementation and funded projects are required, and appropriations are authorized for fiscal years 2026 through 2030.
