With the lake at record levels, there is about 27 billion gallons of water that need to be released from the lake before its down to "draw-down" level. I don't have my formula book handy, but 27 billion gallons sitting at 505 feet above sea level represents a LOT of potential energy. A quick google search
http://www.tsgc.utexas.edu/archive/d...rage/full.html indicates that a constant 30 megawatts per hour could be generated for 40 days. Too bad most of it cannot be harvested. Does anyone know how much electricity is actually generated along the water path from Winnipesaukee to the sea?
