Trent And Mersey Canal Derwent Mouth Lock

The Derwent Mouth Lock is a lock chamber, gates, and leat built in 1770 by engineer James Brindley, with minor later repairs. The lock features a red brick chamber with stone copings and both metal and wooden gates. The chamber is approximately 12 feet deep and has small metal bollards along either side, as well as 20th-century steps on the south side. The gates have wooden frames with metal plates attached, metal balance beams weighted with concrete, and iron handrails at the top. There are 20th-century concrete semi-circles with brick steps on either side. The eastern gates utilize barrel gearing for the paddles, while the western gates have rack and pinion mechanisms. There is an additional pair of rack and pinion mechanisms located further to the west, and to the north side, there is a wide stone leat. This lock was constructed as part of the Trent and Mersey Canal.
