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.
City Mill River is part of the Bow Back Rivers in London, England. It formerly fed City Mill, used for the production of chemicals in the late nineteenth and early twentieth centuries. In the 1930s, the mill was removed and the river was isolated from the tides by the construction of locks at both ends. City Mill Lock, at the southern end, has been refurbished and reopened in 2010.

Aike Beck or the Lockington Navigation was a stream in the East Riding of Yorkshire, England, which was constructed as a navigation in the late 18th century, and ceased to function as such in the 1850s. The water supply came from Bryan Mills Beck and Scorborough Beck, but in 1988, these were diverted to feed into Arram Beck, and most of the channel was filled in with material from the flood banks.
Ponders End is the southeasternmost part of Enfield, north London, centred on the Hertford Road. Situated to the west of the River Lee Navigation, it became industrialised through the 19th century, similar to the Lea Valley in neighbouring Edmonton and Brimsdown, with manufacturing giving way to warehousing in the late-20th century. The area consists heavily of social housing, with streets also lined with 19th and early-20th century suburban terraced housing.

It begins at the Middlesex Filter Beds Weir, below Lea Bridge, and is situated in the (modern) London Borough of Hackney.
