| Additional Information: | A 'site file' exists for this property. It contains additional information such as correspondence, newspaper clippings, or historical information. It is a public record and may be viewed in person at the Wisconsin Historical Society, State Historic Preservation Office. Photo Codes FCS 4/12, 4/13. The present lock, which is oriented on an WSW/ENE axis was built in 1878 to replace one of composite construction. The 144 by 35.6 foot lock chamber and wing walls are comprised of quarried limestone blocks, the sides of which are capped with quarried coping and a pipe railing. 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 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 adjacent 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 10.2 feet of lift as it moves crafts from the 622.50 feet above sea level upper pool to th 612.50 feet above sea level lower pool. It can be filled in three minutes and thirty-three seconds, while it can be discharged in two minutes and forty-four seconds. |
