The River Lea is in South East England. It originates in Bedfordshire, in the Chiltern Hills, and flows southeast through Hertfordshire, along the Essex border and into Greater London, to meet the River Thames at Bow Creek. It is one of the largest rivers in London and the easternmost major tributary of the Thames.
The Limehouse Cut is a largely straight, broad canal in the East End of London which links the lower reaches of the Lee Navigation to the River Thames. Opening on 17 September 1770, and widened for two-way traffic by 1777, it is the oldest canal in the London area. Although short, it has a diverse social and industrial history. Formerly discharging directly into the Thames, since 1968 it has done so indirectly by a connection through Limehouse Basin.
The Hertford Union Canal or Duckett's Cut, just over 1 mile (1.6 km) long, connects the Regent's Canal to the Lee Navigation in the London Borough of Tower Hamlets in East London. It was opened in 1830 but quickly proved to be a commercial failure. It was acquired by the Regents Canal Company in 1857, and became part of the Grand Union Canal in 1927.
The Lee Navigation is a canalised river incorporating the River Lea. It flows from Hertford Castle Weir to the River Thames at Bow Creek; its first lock is Hertford Lock and its last Bow Locks.
Bow Back Rivers or Stratford Back Rivers is a complex of waterways between Bow and Stratford in east London, England, which connect the River Lea to the River Thames. Starting in the twelfth century, works were carried out to drain Stratford Marshes and several of the waterways were constructed to power watermills. Bow Creek provided the final outfall to the Thames, and the other channels were called Abbey Creek, Channelsea River, City Mill River, Prescott Channel, Pudding Mill River, Saint Thomas Creek, Three Mills Back River, Three Mills Wall River and Waterworks River.
The Stort Navigation is the canalised section of the River Stort running 22 kilometres (14 mi) from the town of Bishop's Stortford, Hertfordshire, downstream to its confluence with the Lee Navigation at Feildes Weir near Rye House, Hoddesdon, Hertfordshire.
Enfield Lock is an area in the London Borough of Enfield, north London. It is approximately located east of the Hertford Road between Turkey Street and the Holmesdale Tunnel overpass, and extends to the River Lee Navigation, including the Enfield Island Village. The locality gains its name from the lock on the River Lee Navigation. Today's Enfield Lock was rebuilt in 1922. The area forms part of the Lee Valley Park and the Enfield Lock Conservation Area. On its eastern boundary Enfield Lock has marshland formerly used as a testing site between the Royal Small Arms Factory and the Gunpowder Mills, beyond this is the village of Sewardstone and the Epping forest boundary. To the south is Brimsdown, the north Waltham Cross and to the west Bullsmoor and Freezywater. Enfield Lock forms part of the London boundary.
The London Borough of Tower Hamlets, in spite of being close to the centre of London and perhaps retaining the idea of it being the docklands area, has over 100 areas of parks and open spaces within its boundaries. These range from the huge to small gardens and squares. In common with all the London boroughs, these green spaces provide "lungs" for the leisure pursuits of the inhabitants.
Old Ford is an area in the London Borough of Tower Hamlets that is named after the natural ford which provided a crossing of the River Lea.
This article contains a complete list of locks and weirs on the River Lea/River Lee Navigation from Hertford downstream.
The Lea Valley Walk is a 50-mile (80 km) long-distance path located between Leagrave, the source of the River Lea near Luton, and the Thames, at Limehouse Basin, Limehouse, east London. From its source much of the walk is rural. At Hertford the path follows the towpath of the River Lee Navigation, and it becomes increasingly urbanised as it approaches London. The walk was opened in 1993 and is waymarked throughout using a swan logo.
Old Ford Lock is a paired lock and weir on the River Lee Navigation, in the London Borough of Tower Hamlets, England. It is at Fish Island in Old Ford and takes its name from the natural ford which used to cross the River Lea.
Pickett's Lock is a lock on the River Lee Navigation in the London Borough of Enfield, England and is located near Edmonton, London. It gives its name to the surrounding area of Picketts Lock. In common with other locks as far upstream as Ponder's End Lock it is large enough to take barges of up to 130 tons. However it has not been upgraded to power operation and so it must be manually operated. It has gate paddles but these do not have gate baffles to mitigate the rush of water into the lock.
Stonebridge Lock (No16) is a paired lock on the River Lee Navigation in the London Borough of Haringey, England and is located near Tottenham, London. 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.
Rammey Marsh Lock is a lock on the River Lee Navigation at Enfield, London, England. The area adjacent to the lock is known as Rammey Marsh and close to the River Lee Flood Relief Channel.
Hardmead Lock (No3) is a lock on the River Lee Navigation at Great Amwell close to the town of Ware.
Ware Lock (No2) is a lock on the River Lee Navigation at Ware. The lock stands adjacent to Ware Weir and is the only lock on the Navigation to be operated and maintained by the Environment Agency.
Old Ford is a place within the London Borough of Tower Hamlets. A number of artificial waterways cross the district.
The Hackney Cut is an artificial channel of the Lee Navigation built in England in 1769 by the River Lea Trustees to straighten and improve the Navigation. It begins at the Middlesex Filter Beds Weir, below Lea Bridge, and is situated in the (modern) London Borough of Hackney. When built it contained two pound locks and a half-lock, but was rebuilt to handle larger barges in the 1850s, and now only Old Ford Lock, which is actually a duplicated pair, remains.
