Regarding Maplewood Historic Park.
The West Troy Weighlock Building, 1850-1915, a Greek-revival structure, was one of several
Until 1850 most freight cargoes were measured by the displacement theory, but the West Troy hydraulic type worked with scales rather than displacement. After a boat entered the lock the lock doors were closed, and then the water was drained out allowing the boat to come to rest on a wooden cradle. Certain rods transferred the boat's weight along a series of levers to the beam of the scales inside the Weighlock building. The Weight Master moved a center balancing weight along the beam which determined the weight of the loaded boat. The weighlock became obsolete after in the late 1800's because the state abolished tolls in order to compete with the railroads.
The first West Troy Weighlock of the Clinton's Ditch era was one of the first three weighlocks built, being erected in 1824. In 1834 this lock was completely rebuilt and overhead a "frame building was erected, with proper offices for the collector, weight-master, and inspector: The old scales, however, were reused. Designed for vessels weight only thirty to forty tons, they were clearly soon inadequate. Amazingly, they continued in use until the Weighlock was once again rebuilt, this time on a site further to the north and away from the crowded Upper Watervliet Sidecut.
