Lee Valley Reservoir Chain

The Chain separates the London Boroughs of Haringey and Enfield to the west, from Waltham Forest and Essex in the east. The corridor includes 13 reservoirs and two to three channels of the Lee, as well as marshes and parkland, up to a mile wide.

During World War I, the settlements on both sides of the Lea were badly hit by German Army and Navy airship raids. It is believed the crews mistook the Reservoir Chain for the Thames and released their bombs on what they took to be central London.{{Cite book |last=Castle |first=Ian |url=https://www.worldcat.org/oclc/166380089 |title=London 1914-17: the Zeppelin menace |date=2008 |publisher=Osprey Pub |isbn=978-1-84603-245-5 |location=Oxford, UK |oclc=166380089}}

The Boundary Commission treats the Thames and Lea as natural barriers within London. When reviewing the boundaries of London's parliamentary constituencies, it concludes that any constituency spanning either river would be artificial and not reflect local communities or identities. The 2018 review compromised on this, allowing a cross-Lea constituency further south, in the Lower Lea where the communities on each side are more integrated due to the greater quantity and quality of the road and rail links across the valley.2018 Boundary Commission proposals for parliamentary constituencies https://boundarycommissionforengland.independent.gov.uk/wp-content/uploads/2018/09/Final-recommendations-report.pdf

The corridor is part of the Metropolitan Green Belt, and its national and international significance for wildlife is reflected by SSSI, Ramsar and SPA designations.Walthamstow Wetlands SSSI details includes reference to other designations https://designatedsites.naturalengland.org.uk/SiteGeneralDetail.aspx?SiteCode=UK9012111&SiteName=&countyCode=&responsiblePerson=&unitId=&SeaArea=&IFCAArea= Lying between some of London's most densely populated areas, the Reservoir Chain and associated open land provide a highly valued ecological, landscape and recreational resource for the people of north and east London.

The Chingford Reservoirs are a Site of Special Scientific Interest (SSSI). The Walthamstow Reservoirs, with the exception of Banbury Reservoir, also form an SSSI.

The reservoirs are fed by the following waters:

• River Lee Diversion
• River Lee Flood Relief Channel
• New River
• The Thames-Lee Water Main{{Cite journal| doi = 10.1680/iicep.1962.05088| issn = 1753-7789| volume = 21| issue = 2| pages = 257–276| last1 = Cuthbert| first1 = E W| last2 = Wood| first2 = F| title = The Thames-Lee Water Main| journal = Proceedings of the Institution of Civil Engineers| accessdate = 2022-07-30| date = Feb 1962| url = https://www.icevirtuallibrary.com/doi/10.1680/iicep.1962.05088}}
