62-704: The River Beane is a short river in the county of Hertfordshire, England. A tributary of the River Lea , it rises to the south-west of Sandon in the hills northeast of Stevenage and joins the Lea at Hartham Common in Hertford . In medieval times there were a number of watermills along the course of the Beane. A few of the buildings and mill races survive. The Beane valley remains mainly rural in character. However, Hertfordshire's population increased substantially in
124-523: A distinctively bow-shaped, three-arched, bridge to be built over the River Lea ( The like of which had not been seen before ), at Bow, the first bridge over the lower Lea. The lower Lea was at that time a wide, tidal and unchannelled river, so the construction of the bridge allowed a far greater degree of social and economic integration between Essex on one side and Middlesex (including the City of London) on

Below Bow Locks the creek forms the boundary between
248-551: A major source of drinking water for London. An artificial waterway known as the New River , opened in 1613, abstracts clean water away from the upper stretch of the river near Hertford for drinking. The Lea's origin in the Chilterns contributes to the extreme hardness (high mineral content) of London tap water. The name of the River Lea was first recorded in the 9th century, although is believed to be much older. Spellings from
310-558: A new cut from Bow tidal gates to the Thames at Limehouse. Although only a little further to the west, access at Limehouse avoided the long loop around the Isle of Dogs for traffic heading towards London. The cut was to be opened on 2 July 1770, but failure of a side wall delayed the event until September and a bridge collapsed into it in December. Traffic began to switch to the new cut, which

The 2012 Olympics was focused in the Queen Elizabeth Olympic Park on the banks of the Lea, and its main Stadium, on an island between two branches of the river, is now home to West Ham United. The Lee Valley White Water Centre in Hertfordshire is another sporting legacy of the games. Various versions of the nursery rhyme London Bridge Is Falling Down make reference to Bow Bridge. The oldest known version could be that recalled by
434-654: Is also used in geology, archaeology, etc. to refer to the Lea Valley . The term River Lea is Cockney rhyming slang for tea. The line of the Lea, and its major tributary, the Stort, has long been used as a political boundary. In the Iron Age the Lea and Stort valleys formed a hotly contested frontier zone between the Catuvellauni to the west and the eastern Trinovantes . The two rivers are assumed to have been
496-680: Is derived). The River Lea flows through the old brewing and malting centre of Ware , and consequently transport by water was for many years a significant industry based there. Barley was transported into Ware, and malt out via the river, in particular to London. Bargemen born in Ware were given the "freedom of the River Thames" — avoiding the requirement of paying lock dues — as a result of their transport of fresh water and food to London during The Great Plague of 1665–66. A local legend says that dead bodies were brought out of London at that time via
558-827: Is in the East of England and Greater London . 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 river's significance as a major east–west barrier and boundary has tended to obscure its importance as north–south trade route. Below Hertford
620-525: Is much greater, and the communities on either side better integrated as a result. The source of the Lea is usually said to be at Well Head inside Waulud's Bank , a neolithic henge at Leagrave Common in Luton , Bedfordshire , although just downstream the river is joined by Houghton Brook , a stream that starts 2 miles (3 km) further west in Houghton Regis . After passing through Luton,
682-562: Is one of the oldest navigations in the country, but the creek is tidal, providing insufficient depth for navigation at low tide. Use of the river for navigation is recorded in documents dating from 1190 and it became the first river in Britain where improvements were authorised by an act of Parliament , the River Lee Navigation Act 1425 ( 3 Hen. 6 . c. 5). The River Lee Navigation Act 1571 ( 13 Eliz. 1 . c. 18) allowed

It seems to be derived from a Celtic (brythonic) root lug -meaning 'bright or light' which is also the derivation of a name for a deity, so the meaning may be 'bright river' or 'river dedicated to the god Lugus '. A simpler derivation may well be the Brythonic word cognate with

During WWI, parts of London on either side of the Lea were badly hit by German Army and Navy airship raids. It is believed the crews mistook the extensive reservoir chain for the Thames and released their bombs on what they took to be central London. The ecological, landscape and recreational importance of
868-620: The Congreve Rocket Factory on the site of Stratford Langthorne Abbey . Improvements were made to the river from 1424, with tolls being levied to compensate the landowners, and in 1571, there were riots after the extension of the River was promoted in a private bill presented to the House of Commons . By 1577, the first lock was established at Waltham Abbey and the river began to be actively managed for navigation. The New River
930-552: The London Boroughs of Newham and Tower Hamlets , in East London. The River Lea rises in the town of Luton in Bedfordshire , and flows to the east and then the south to reach the River Thames at Leamouth . The final 2.25 miles (3.62 km) are known as Bow Creek, and follow a meandering route across a low-lying area formerly called Bromley Marsh, but now occupied by gas works and trading estates. The river
992-588: The Middle Lea . During the Middle Ages , Temple Mills , Abbey Mills , Old Ford and Bow were the sites of water mills (mainly in ecclesiastic ownership) that supplied flour to the bakers of Stratforde-atte-Bow, and hence bread to the City. It was the channels created for these mills that caused the Bow Back Rivers to be cut through the former Roman stone causeway at Stratford (from which the name
1054-475: The Prescott Channel to maintain water levels on the Lea, within the park at a depth of 2 metres (7 ft). This allowed access to the site by 350–tonne barges with the aim that at least half of the material required for construction could be delivered or removed by water. In January 2024, the River Lea burst its banks as Hackney Wick residents tell of 'knee-high' flood water. Millfields Park on
1116-480: The Queen Elizabeth Olympic Park . In that park, and just to the south of it, the river's course splits, running almost entirely in man-made channels, the Bow Back Rivers . These channels were once much more numerous and originally created to power water mills including, at the southern end, the restored tidal mill called Three Mills . The area around the Bow Back Rivers subsequently became a thriving industrial zone. Around Bow Creek , major industry prevailed, including
1178-614: The River Lee Diversion . These reservoirs come to an end on the boundaries of the London Boroughs of Haringey and Hackney and form part of a broad undeveloped green space, a mile (800 m) wide in places, which extends deep into London. On Hackney's northern edge, the Lea shifts to a south-south-easterly direction, the reservoirs end, but the broad green corridor continues as the river passes through Walthamstow Marshes , Leyton Marshes , Hackney Marshes and
1240-490: The River Thames . The Lee Navigation was established by Acts of Parliament and only that spelling is used in this context. The Lee Valley Regional Park Authority also uses this spelling for leisure facilities. However, the spelling Lea is used for road names, locations and other infrastructure in the capital, such as Leamouth , Lea Bridge , the Lea Valley Walk and the Lea Valley lines (railway). This spelling
1302-534: The Thames Ironworks , Bromley-by-Bow Gasworks and West Ham Power Station . In the 1960s and 1970s, changing economic conditions led to a steep decline and deindustrialisation along this section of the Lea. The river was historically tidal as far north as Hackney Wick , but now the tide is held back by the Bow Locks between Bromley-by-Bow and West Ham. Although watercraft can follow the Lea down to

The creek gave access to Abbey Creek and the Channelsea River, which connected to the old course of the River Lea near Hackney Marshes . Most of this waterway has since been culverted. Water also entered
1550-403: The 1990s until about 2014 there was only seasonal flow. An indication of the scale of the decline in flow is that the section at Walkern was once big enough to power a watermill and to support watercress beds. The lower Beane is more robust and there has continued to be regular flow through Watton-at-Stone , Stapleford and Waterford until the confluence with the River Lea. However, overall
1612-454: The Lea at Hackney, is the reputed site of a victory of Aescwine of Essex over Octa of Kent in 527, which allowed Aescwine to become the first King of Essex . However, the historicity of these events and the very existence of Aescwine are disputed. Somewhere between 878 and 890, the Treaty of Alfred and Guthrum was drawn up that amongst other things used the course of the Lea to define

This work is thought to have included a new cut between Old Ford and Bow Locks, which is known as Bow River and, like Bow Creek, is not subject to tolls for those using it. During the great plague of 1665, bargemen on the river continued to supply food to the population of London and were granted permission to navigate
1736-466: The Lower Lea every month. Water extraction, for drinking water, farming and industry, has led to a reduction in river flow impacting wildlife and concentrating the pollutants present in the remaining river water. Projects such as that led by Thames21 installing reedbeds help to remove pollutants whilst oxygenating the water, as well as creating habitat for the likes of water voles and improving
1798-427: The Thames without having to ask a Thames Lighterman for assistance, in recognition of the risks they had taken. Because of the importance of the river for navigation, the engineer John Smeaton was asked to survey it and to suggest how it could be improved in 1765. He produced a report in 1766, which recommended replacing the flash locks with more modern pound locks , and more significantly for Bow Creek, making

In their early days, Tottenham Hotspur played their games at Tottenham Marshes on the Middle Lea while Leyton Orient have had a number of home grounds in the Lower Lea Valley , with both having their current grounds within a mile of the river. West Ham United was established as the works team of the Thames Ironworks ,
2046-442: The area that year, ahead of the 2012 Olympic Games . The river is threatened by pollution, with sewage frequently discharged into the river as well as less common events causing major damage, such as an oil leak in 2018, or the toxic runoff from a warehouse fire in 2019. The sewage pollution, as well as that of fertiliser washed in from agricultural fields causes eutrophication , an excess of nutrients, which not only unbalances
2108-637: The border between the Danes and the English. In 894, a force of Danes sailed up the river to Hertford, and in about 895 they built a fortified camp, in the higher reaches of the Lea, about 20 miles (32.2 km) north of London. Alfred the Great saw an opportunity to defeat the Danes and dug a new channel to lower the level of the river, leaving the Danes stranded. In 1216, during the First Barons' War ,
2170-497: The boundaries of London's parliamentary constituencies, the Boundary Commission treats the Thames and Lea as London's major internal barriers. It will not allow a new or altered constituency that spans either river, viewing such a construct as artificial and not reflective of local communities or identities. They have compromised on this further south, on the lower Lea, where the quality and quantity of cross-river links

The whole of the Lea was subsequently used as the boundary between English-ruled territory to the west and the Danelaw , established in the late 9th century, to the east. From around the ninth or tenth century, and the establishment of counties in this part of England, the Lea-Stort line has formed
2294-547: The creek through the sluices of the tide mills at Three Mills . Ships were built at the Orchard House Yard , in the southern reaches at Leamouth , and launched in the creek where they could travel north along the River Lee Navigation or south to the River Thames . In 1810, an iron bridge was built spanning the creek – just south of the modern A13 bridge . The abutments have been reused for

Affinity Water was told to take less water from its pumping station near Aston, even though obtaining water from a less environmentally damaging source was difficult as the River Lea's catchment area as a whole is under pressure. There have been initiatives to improve the condition of lower stretches of the river, where there are issues regarding water quality and weirs. For example, where it passes through

In 1648 during the second English Civil War a Royalist force crossed the Thames from Greenwich and hoped to cross Bow Bridge, over the Lea and into Essex. After inconclusive clashes with the Tower Hamlets Militia and other Parliamentarian forces, an engagement known as
2542-473: The gates should be replaced by a conventional pound lock, but this was not carried out. However, in 1852 a lock was constructed, although the gates also remained in place. The lock was rebuilt and shortened in 1900, and a second lock constructed beside it in 1931. Higher floodgates and walls were added in 2000 to prevent the inundation of the Lee Navigation when the level of the tide in the creek exceeded

2604-452: The historic boundary between Essex to the east and Hertfordshire and Middlesex to the west. Within London the river is always used as a boundary between London Boroughs - which in turn inherit more ancient county and parish boundaries which also used the Lea as a boundary. Between 1889 and 1965, the lower Lea was the eastern boundary of the County of London with Essex . When reviewing
2666-559: The level in the navigation. Access from the creek to Bow Back Rivers was altered in the 1930s as part of an upgrade carried out to improve the waterways and to provide employment. The Prescott Channel was constructed to bypass the tide mills, and gave access from the creek to the Three Mills Wall River and the Waterworks River . The lock and sluice structure at the mouth of the new channel became disused in
2728-487: The marshes known as Wanstead Slip (now in Leyton). The route then continued through Essex to Colchester . At this time, the Lea was a wider river, and the tidal estuary stretched as far as Hackney Wick . Evidence has been found of a late Roman settlement at Old Ford, dating from the 4th and 5th centuries. In 1110, Matilda , wife of Henry I , reputedly took a tumble at the ford, on her way to Barking Abbey and ordered
2790-506: The modern Welsh "Li" pronounced "Lea" which means a flow or a current. Much of the middle Lea were historically known as 'Mereditch', the first element deriving from the Old English ‘gemaera’, meaning boundary. This was due to that section of the river’s role as the dividing line between territories, for instance separating Middlesex and Essex. By the 20th century 'Mereditch' had evolved to 'Mare Dyke' and referred to just one channel of
2852-486: The occasional seal . Some boat trippers reported observing on 5 August 2005 a Canada goose being pulled underwater very quickly. The London Wildlife Trust suggested that this was most likely caused by a pike . In 2011, Mike Wells claimed that he saw a "goose go vertically down" in the river. Again a pike or mink was suggested as most likely. Vice Magazine suggested that Wells' story may have been invented to publicise authorities' attempts to evict houseboats from
2914-480: The other than had been possible before. Lea Bridge , the second bridge over the lower Lea was built after 1757, to replace the pre-existing ferry. It connected Clapton to the west, and Leyton and Walthamstow to the east. The Iron Bridge carrying the Barking Road over the river to Canning Town was built in 1810. There are significantly more crossings over the more central Lower Lea , than there are over

Documents from 1588 suggest that the gates opened automatically when the incoming tide reached a level with the river above them. Another rebuilding took place in 1721, again by the tide mill owners, and with the City of London appointing a surveyor to oversee the work. Smeaton, in 1766, suggested that
3038-524: The restoration of the upper Beane which was discussed was to use recycled water from sewage treatment works. For decades sewage from the Stevenage area has bypassed the river, being pumped down the Beane valley to Rye Meads near Hertford for treatment and eventual discharge into the River Stort . However, the water could theoretically have been discharged into the Beane if treated further upstream. In
3100-540: The river and its surrounding areas change significantly. Around Hertford, the Lea is joined by a number of major tributaries: the Mimram , Beane , Rib , Ash , and then the Stort . This extra volume of water has created a broad flood plain with sometimes steep hills on either side. The river passes through this valley in several channels, which are a result of both human intervention and natural causes. The increased flow made
3162-468: The river and its surrounding land has been recognised through inclusion in a number of parks and by several planning policy designations. Much of the river lies within the Lee Valley Park . Some of the land surrounding the river has been designated as Metropolitan Green Belt or Metropolitan Open Land in order to prevent further urbanisation. The river contains fish and other wildlife such as

In the Roman era , Old Ford , as the name suggests, was the most downstream crossing point of the River Lea. This was part of a pre-Roman route that followed the modern Oxford Street , Old Street , through Bethnal Green to Old Ford and then across a causeway through
3286-494: The river between Chingford and Enfield . The channel was replaced by parts of the Lee Valley Reservoir Chain in the mid 20th century. The River Lea is the major component in a number of place-names, including Leagrave , the suburb of Luton where the source of the river is located, and of Luton and Leyton : both mean "farmstead on the River Lea" . The spelling Lea predominates west (upstream) of Hertford , but both spellings ( Lea and Lee ) are used from Hertford to

The extensive level of waterborne trade led the historian John Stow , writing in 1603, to describe the Lea as “this pleasant and useful river”. The riverside has hosted a number of major armaments manufacturers, such as the Waltham Abbey Royal Gunpowder Mills , the Royal Small Arms Factory at Enfield Lock (which is now a housing development known as Enfield Island Village ) and
3410-488: The river has performed badly in assessments by the Environment Agency of flow level. The state of the upper Beane resulted in calls for the river's restoration. The management plan for the river includes the objective that there is adequate flow along the length of the river to support a ‘good status’ chalk stream ecology (as defined by the European Union 's Water Framework Directive ). One possible approach to
3472-483: The river has since medieval times had alterations made to make it more navigable for boats between the Thames and eastern Hertfordshire and Essex , known as the Lee Navigation . This stimulated much industry along its banks. The navigable River Stort , the main tributary, joins it at Hoddesdon . While the lower Lea remains somewhat polluted, its upper stretch and tributaries, classified as chalk streams , are

The Stort, the most important tributary of the Lea, joins a short distance from Hertford at Feildes Weir , and is itself navigable as far upstream as Bishops Stortford . The Hertford East railway line passes along the west side of the Lea's flood plain, from Hertford to Tottenham, improving

In the case of the Beane, a licence was given to abstract water near Aston for Stevenage's water supply. The river has since been adversely affected by over-exploitation of the chalk aquifer in its upper reaches. The photo shows a dry section south of Walkern where from
