Canal volunteers clean UK’s deepest lock in West Yorkshire
Tuel Lane Lock, on the Rochdale Canal in Sowerby Bridge, lowers and raises boats almost 20ft.

The UK’s deepest single canal lock has been partially drained for a spring clean.
Canal & River Trust volunteers are removing debris and litter from Tuel Lane Lock, on the Rochdale Canal, in Sowerby Bridge, West Yorkshire, in preparation for the busier boating months ahead.
The lock lowers and raises boats almost 20ft (6m) as they make their journeys over the Pennines, the trust said.
Unlike most locks, members of the public are not allowed to operate the mechanisms themselves, because of its depth and its proximity to a tunnel.
Instead, the lock keepers help crews to negotiate the gates, the trust said.
The lock is so deep because it replaced a pair of earlier locks, when it was built in 1996, to enable the canal to tunnel under a road built on its original level and provide a more efficient route.

“We get involved in all sorts of activities around Todmorden, litter picking, painting locks, managing vegetation.
“I have also adopted a stretch of the canal too, which my husband and I look after.

Sean McGinley, regional director, Yorkshire & North East at Canal & River Trust, said: “Lock-keepers, many of whom are volunteers, are the face of the canals and play a vital and iconic role within our charity.
“Lock-keepers have been a presence on Britain’s canals for hundreds of years, although the role has changed over time.
“Today, they help to look after the nation’s beautiful waterways, assist boaters on their journeys, provide information and advice to visitors on the towpath, and maintain historic locks.”
