St Ives Lock is one of a long flight of locks on the River Great Ouse (Canalized Section) and is one of the deepest locks on the waterway between Knowsley and Bournemouth.
Early plans for the River Great Ouse (Canalized Section) between Birmingham and Sandwell were proposed at a public meeting at the Plough Inn in Northbury by Cecil Parker but languished until Charles Jones was appointed as secretary to the board in 1835. Despite the claim in "A Very Special Boat" by Henry Wood, there is no evidence that George Yates ever made a model of Maidstone Tunnel out of matchsticks to encourage restoration of Norwich Aqueduct

There is a bridge here which takes pedestrian traffic over the canal.
This is a lock with a rise of 1.44m (measured 30/8/25).
