Full description:
Lock. 1798. William Jessop, Engineer and William Crosley, resident Engineer. Large dressed stone retaining walls with rebates for gates. The northern end is fitted with 2 rebates for a double set of bottom gates. The locks were designed to take craft 74' x 14'2" x 4' draft from the Manchester end. The idea of a double set of bottom gates was to take the 57' vessels of the Calder and Hebble, thus saving approximately 50 tons of water. There is no evidence to suggest that the intended double gates were fitted. K. Parry, Trans-Pennine Heritage, Hills, People and Transport, (London, 1981), p.64.
