Locks

Locks. . The locks at the Weighlock are designed in the same manner as a standard lock. However, the basic function between a traditional lock and a weighlock differ. In a traditional lock, flooding the chamber was a simple function of gravity. The locks create a pool on both the upper and lower ends of the lock. A series of small "Sluice Gates" were set in the bottom of each gate. In a traditional lock, the upper pool being higher than the lower pool allowed gravity to flush water. To empty the lock, water was flushed through the lower pool's sluice gates back into the canal. , The weighlock worked slightly differently. Unlike a traditional lock, the weighlock does not create a pool on either side. Rather, it is set to the main channel side wall of the lock. In a traditional lock, the upper pool is always higher than the lower pool allowing gravity to flush water. In a weighlock the pools are even so a sluice gate was set into the wall of the stone chamber itself. Gravity was then used to flush water through a culvert into a local creek.
