The Prescott Channel was built in 1930–35 as part of a flood relief scheme for the River Lee Navigation in the East End of London, England, and was named after Sir William Prescott, the then chairman of the Lee Conservancy Board.〔(''Notes and News'' ) (April 2007) (Greater London Industrial Archaeology Society)〕 Rubble from the demolished Euston Arch was used in 1962 to improve the channel,〔''Euston Arch found at bottom of river'', ''The Times'' (4 June 1994).〕〔(''Where are the remains of the arch?'' ) (Euston Arch Trust) accessed 16 July 2008〕 which forms part of the Bow Back Rivers. ==Details== Three Mills Lock is a lock in the channel to allow passage of freight for the London 2012 Olympics by a process of canalisation (with the result of stopping the tidal flow) on the channel and the River Lee northwards. It was constructed between March 2007〔( ''East End rivers set for upgrade'' ) (BBC News)〕 and June 2009.〔("Waterway revived as Olympic route" ), BBC News 5 June 2009〕 The project was credited with offering additional benefits:- "As well as helping barges carrying construction materials and recyclables between Stratford and the River Thames, the lock will also create new opportunities for leisure boats, water taxis, trip boats and floating restaurants." A major benefit for British Waterways was the increased value of the land which it holds in areas no longer subject to flooding,〔(【引用サイトリンク】title=Prescott Channel Water Control Structure Project Explanatory Statement )〕 which it was expected would exceed the cost of the project. The lock is 62 metres long, 8 metres wide and 2.4 metres deep, and can hold two 350 tonne barges (other locks on the Lower Lee limited barges to about 120 tonnes).〔 It was designed by Tony Gee and Partners and built by Volker Stevin.〔British Waterways press release: (New lock provides sustainable legacy for London )〕 On 2 June 2008, work on the channel brought up a ''Hermann'' Second World War time bomb. Residents were evacuated, tube and rail services were disrupted, and flights from London City Airport were curtailed during the emergency. The 67-year-old, booby-trapped bomb was finally made safe, after five days, in a controlled explosion that threw 400 tonnes of sand into the air. Major Matt Davies, of the Army Bomb disposal unit said "If it had gone off in wartime there would have been large fragments up to a mile away which could have destroyed buildings and sewers". He added "This is the biggest unexploded bomb we have found in central London."〔(''"Hermann" the German bomb says farewell with a bang—after 67 years'' ) (East London Advertiser, 6 June 2008) accessed 9 June 2008〕 In 2009, again as part of the project to build the lock, 29 stones from the Euston Arch were raised from the river bed and presented to the Euston Arch Trust. One stone had already been salvaged in 1994 by Dan Cruickshank, as part of a BBC Television programme called 'One Foot in the Past'.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Prescott Channel」の詳細全文を読む スポンサード リンク
