Say hello to a fishbelly sluice...

OLYMPICS: British Waterways (BW), working with contractors Volker Stevin, recently installed a ‘fishbelly’ sluice gate as part of the £20m Prescott Lock project. The work represents a major milestone towards the restoration of the waterways that criss-cross the Olympic site and will create a sophisticated new water control structure for the Lower Lea Valley.

The new, state-of-the-art lock will provide access to the Olympic development area for 350-tonne barges, which will transfer their cargos of aggregates onto lorries for transport to the budding Olympic facilities.

The end result will be to take hundreds of lorry journeys a week off already crowded local roads, in the process saving thousands of tonnes of CO2 as well as linking the Olympic Park into the Thames Gateway, creating a platform for a new Water City in the East of London.

The Prescott Lock and Water Control Structure, which is funded by BW, the Department for Transport, London Thames Gateway Development Corporation, the Olympic Delivery Authority (ODA) and Transport for London will, in part, re-establish an historic structure which previously existed at this location and maintained the water upstream on the Bow Back Rivers at a navigable depth.

The project will eventually see twin water control gates, a 62m x 8m tidal lock, a footbridge, a lock control building, fish pass and weir gates.

'This is an important step towards the long awaited restoration of the Bow Back Rivers,' said Mark Bensted, BW’s London director. 'Prescott Lock is an exciting project, using modern engineering techniques to reintroduce navigation to these waterways and support the sustainable regeneration of east London.'
