Stonebridge Lock

Stonebridge Lock is a paired lock on the River Lee Navigation – a canalized river – in the London Borough of Haringey, located in the Lee Valley Regional Park. Like other locks as far as Ponder’s End Lock, it is large enough to take barges of up to 130 tons. The primary lock has been upgraded to mechanical operation, but the secondary lock is operated manually. The lock is situated between the Lockwood Reservoir on the Walthamstow side and Tottenham Marshes on the Tottenham side. The lock can now be reached by a network of pedestrian paths, or by car, with foot and cycle access via the towpath that forms part of the Lea Valley Walk. Under the ownership of Lee Valley Regional Park Authority, Tottenham Marshes is being managed for people and wildlife. Trees, shrubs, rough grassland and waterways combine to make an important wildlife area.

In conjunction with British Waterways and Halcrow acting as project and construction managers, the facilities building at Stonebridge Lock was erected as part of the regeneration of the navigation canal and the marshes. It is sited adjacent the canal and the lock keeper’s cottage and encompasses toilet and changing provisions, a classroom and canoe store available to public, canal habitants and travelers, and for use by local schools.
