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!
