State Dam Loan/Grant Funding Program  

New Hampshire has sources available to assist dam owners with repair, abandonment, or removal of dams.

New Hampshire’s Dam Maintenance Revolving Loan Fund was established in 2009 under state statute RSA 482 482:55-a. Some rules still need to be established, but the current balance of the Fund is still very small.  
Regarding funding for dam removals, the State of New Hampshire does not have a specific loan/grant program for dam removals.  However, one of the responsibilities of the River Restoration Coordinator, who is part of New Hampshire’s Dam Safety Program, is to assist dam owners in identifying potential funding sources, including state and federal resource agencies and non-governmental organizations, to offset the costs of dam removal.  Click here to find out more about New Hampshire’s River Restoration Program.
