Ball Mountain Flooding
Ball Mountain Dam before the flooding in this May 2023 photo. Ball Mountain Lake has a permanent pool with a depth of 25 feet that covers 20 acres. From mid-May to mid-October, this pool is kept at a depth of 65 feet, enlarging the pool area to 75 acres, to increase the seasonal recreational opportunities. Ball Mountain Lake can store up to 17.8 billion gallons of water for flood control purposes. Holding that much water would have the reservoir pool cover 810 acres and extend 6.5 miles upstream through Londonderry. During this storm, at their peaks, the seven #USACE dams along the Connecticut River Basin in Vermont and New Hampshire were collectively storing and holding back 60 BILLION gallons of storm water. This is equivalent to 91,000 Olympic-sized swimming pools!

    The Pawcatuck River Coastal Storm Risk Management Feasibility Study

       This proposed plan is presented  to facilitate public involvement in the review and commenting on the remedy selection process for the Nantucket Memorial Airport (NMA) Formerly Used Defense Site (FUDS.) 
        The Army Corps of Engineers is proposing a No Action under the Comprehensive Environmental Response, Compensation, and Liability Act for the Munitions Response Site-1, Project Number D01MA049901 at NMA located on Nantucket Island, MA.  The proposal was prepared using the Guide to Preparing Superfund Proposed Plans, Records of Decision, and Other Remedy Selection Decision Documents (USEPA, 1999).
        The final decision for NMA Site-1 site will be made after reviewing and considering all information submitted during the public comment period. The proposed decision may be modified based on new information or public comments. The public is encouraged to review and comment on the proposed plan.
        The FUDS program addresses the potential explosives safety, health, and environmental issues resulting from past munitions use at former defense sites under the Department of Defense (DoD) Military Munitions Response Program, established by the U.S. Congress under the Defense Environmental Restoration Program.  
        FUDS only applies to properties that transferred from DoD before October 17, 1986 and the first priority of USACE is the protection of human health, safety, and the environment. 
        The Army is the executive agent for the FUDS Program, and USACE is the lead agency for investigation/reporting and remedial decision-making at this munitions site with regulatory support provided by the Massachusetts Department of Environmental Protection (MassDEP).
