WATFORD GRAND UNION CANAL SP56NE 5/283 Flight of 7 locks and side ponds

- II

Staircase of 4 locks; as part of flight of 7 locks. Early C19, refurbished 1902 (datestones). Retaining walls blue brick with stone coping. Wing walls at top of flight blue brick. Wooden gates, balance beams in steel to some locks. C20 footbridges. The paddle gear is probably 1902 but may incorporate some earlier work. The gear is notable as being still connected to the paddle by wooden rods, mostly replaced elsewhere by metal rods (note from A.T. Conder, Curator, Waterways Museum, Stoke Bruerne). West of the locks is a group of side ponds for conservation of water. The Grand Union Canal was authorised by Act of Parliament in 1810, the Watford section was opened in 1814. (A.H. Faulkner, The Grand Junction Canal, 1972, p.187-8 and p.197).
