    The dry-dock at Lock 47 was constructed about 1852 by Thomas J. Hassett (Mastrangelo1987:10). It was used to repair canal boats. Located on the berm side of the bypass flume, the dry-dock ran parallel to both the lock and the flume. It had battered dry-laid stone sidewalls, with stop-plank slots at the lower end. The width of the dock at the top was 26 feet and 21 feet at the bottom. It was 103 feet long with an upper wall of a roughly-coursed limestone.
    Current Condition
    The dry-dock is now little more than a wide ditch. Little evidence of the side walls exist and it is filled with vegetation and silted in. There remains some stonework at the lower end.
