Woodberry Wetlands, managed by London Wildlife Trust, is an 11-hectare site between Harringay and Stoke Newington.
Today Sir David Attenborough joined London Wildlife Trust staff and volunteers on the press day mark the opening of the reservoir to the public for the first time in 200 years.
Sir David said access to the natural world was a "birthright" and should not be regarded as a luxury.
He added: "We are part of it and if we lose contact with the natural world, you lose contact with a great source of pleasure and delight which is your birthright."
The new wetlands reserve is based in and around the early 19th Century east reservoir. Both it and the New River which feeds it are still owned by Thames Water and are a part of London's daily water supply.
London Wildlife Trust said the site had more than 13,000sq metres of reed bed and 550sq metres of hedgerow, wildflower meadows and fruit trees to attract birds, bees, butterflies and other insects.
The Wetlands is open to the public both today and tomorrow. See our event listing for details.
Great set of pics, Hugh.
You can't get better than Sir David everything he touchs turns to gold. Great reportage Hugh
Hugh, many thanks for the report and the excellent photos. We're lucky to have such a wonderful amenity, almost on our doorstep.
Terrific photographic record of a milestone event - 'a picture (can) say more that a thousand ...'
Great pics! This afternoon, my wife and I took our two little 'uns, and my parents who were up for the day. Seems a very nice amenity, and when it's all bedded down it's going to be a very beautiful spot. Could do with a few more benches around the pathway though! One pity is that Thames Water didn't get the memo and do their bit by tidying up the New River Path leading up to the site.
I've already asked about benches and have been told that they will be placing more around the site in the coming weeks.
Yes, one of the staff (?) overheard a few people mentioning it, and interjected to say that it was her most received feedback of the day (other than general praise)!
They're traditionally had a problem with alcoholics congregating around benches which is really unpleasant for those on the 2nd floor who are effectively denied the amenity of their balconies on sunny days. Sounds like they've solved that problem, I wonder how?
