Additional Information:Photo code: FCS 4/9. The present lock, which is oriented on an WSW/ENE axis was built in the 1850s. The 144 by 35.6 foot lock chamber is comprised of dry rubblestone and lined with timber planking, the sides of which are capped with concrete coping and a pipe railing. The lock's wingwalls, however, are built of quarried limestone blocks. Each of the four lock gates is constructed of squared wooden timbers that are laid horizontally atop one another and joined with structural ties. Adjacent to each gate is a concrete platform that contains a tripod. A vertical shaft extends the height of the tripod. A handle is fixed to the top of the shaft, while the bottom of the shaft contains a gear that drives a horizontally placed spar, the end of which is attached to a lock gate. (It is a horizontal rack and pinion system.) Depending on which way the handle is turned, the spar is either taken in, thus opening the lock gate, or it is pushed out, in which case the gate closes. The chamber is flooded by four butterfly valves that are set in the floor of the lock, immediately upstream from the structure. As the valves are opened, water passes down into a culvert with a 90 degree turn, which then directs it under the upstream sill and straight into the chamber. Each valve is adjusted by a geared mechanism that sits on the lock's coping. A metal shaft connects the valve to the adjusting mechanism, three of which are placed adjacant to each of the upstream corners of the lock. The chamber is discharged through six small butterfly valves found at the bottom of the two downstream gates. There are three valves per gate. These valves are operated by the levers atop each gate. The gates contain a cat-walk that facilitates moving from one side of the lock to the other. The lock provides 10.4 feet of lift as it moves crafts from the 612.50 feet above sea level upper pool to the 602.15 feet above sea level lower pool. It can be filled in three minutes and thirty-one seconds and discharged in two minutes and fifty-eight seconds.

The general date of construction is assumed because this locak retains the type of lock construction originally used in the 1859s. It has, nevertheless, been rehabilitated many times, a recent example of which was in 1950.
