National waterways charity Canal & River Trust is aiming to complete its works at the Welsh Harp Brent Reservoir by the middle of April, and then allow it to re-fill with water.
The Welsh Harp Brent Reservoir was built in 1835 to supply water to the Grand Union Canal. As well as being a place for sailing, watersports and walking, the reservoir is protected as a Site of Special Scientific Interest (SSSI) for the rich diversity of wildlife found on site, including water birds and 16 protected plant species.
Ros Daniels, the Canal & River Trust’s London & South East director, explains: “The Welsh Harp Brent Reservoir is one of London’s most significant urban wild spaces and provides a much valued area of green open space for people and wildlife.
“To carry out our essential maintenance works at the reservoir, we’ve had to drain around 1,000 mega litres of water, enough to fill 400 Olympic-sized swimming pools. We’ve rescued around 100,000 fish and our volunteers and contractors have removed over 1,000 bags rubbish, as well as dustbins, tyres, e-bikes, scooters, safes, clothing and suitcases.
“Over the winter months, we’ve also been carrying out a series of environmental improvements at the Welsh Harp, including creating new nesting areas in the reed beds for wetland birds, willow coppicing and removing silt from one of the ponds. Once the reservoir has refilled with water, with the support of the Welsh Harp Conservation Group, we plan to install 13 new island habitats for common terns, one of the species of water bird that lives on the reservoir.”
“Unfortunately the succession of winter storms and high rainfall levels we’ve experience over the winter have caused us significant delay. We’ve worked closely with Natural England to develop a plan to minimise the impact of this delay on the nesting birds that rely on the reservoir. We’ve installed visual bird scarers, including holographic tape and decoy birds of prey, to discourage birds from nesting until the reservoir has refilled. We expect this to happen by the end of May, but it depends on how much rain we get.”
The reservoir remains open to the public throughout the works, but signs are in place warning visitors not to walk on the reservoir’s drained area and mud for their own safety.
