When completed in 1766, Langley Edwards' Grand Sluice consisted of three channels each 17 feet (5.2 m) wide, fitted with pointed gates on both sides, and a lock adjacent to the north bank, which could be used as an additional flood relief channel if required. The lock was originally very small, but was lengthened to its current 41 by 12 feet (12 by 3.7 m) in 1881. The pointed doors on the non-tidal side of the sluice were replaced by steel guillotine gates between 1979 and 1982.[1]
