Information: Flagstaff Lake used to be smaller until the Long Falls Dam impounded the Dead River in 1950,[1] enlarging the lake and turning it into a reservoir used for hydropower electricity production by regulating the flow of the Dead River into the Kennebec River. At the time, the river drive was still a primary means of delivering timber to the pulp mills downstream. Although improved highways and the trucking industry have replaced the river drive, water releases continue to serve hydroelectric power-generating plants downstream.
