Tuel Lane Lock on the Rochdale Canal in Sowerby Bridge is 20ft deep – meaning vessels using it are raised to more than the height of a double decker bus.
It is one of the few locks that boaters cannot operate themselves, and must be assisted by the lock-keeper.
It was built in 1996 as part of a restoration of the canal, and replaced two Victorian locks to enable the canal to tunnel beneath a road for a more efficient route.
Canal and River Trust volunteers carried out the dredging and clearance work.
