was dismantled, and, under very difficult freighting conditions due to snow and weak ice, the two small generating units were brought to Island Falls, where they were permanently installed in 1933. During the period of operation this plant supplied 4,698,000 kWh of electrical energy for construction purposes, at an average cost of 4.35 cents per kilowatt-hour. Notes A dry season in 1929 resulted in low water level in 1930 and it became necessary to find additional sources of water in order to maintain the amount of power required for construction. The outlet of Barrier Lake was cut through, and its of water was lowered in order to furnish enough power to complete the construction at Island Falls. After construction, the outlet was replaced by a faced, rock-filled, timber-crib weir, thus restoring Barrier Lake to its former elevation. References Marshall, M.H.
