Wader Lake project reaching new depths
A project designed to bring wetland wildlife and people closer together is reaching new depths out on WWT Washington’s reserve.
Wader Lake, one of our site’s best wildlife hotspots, has been the focus of desilting works for more than a year, with almost 1,000-tonnes of sediment removed to date – the equivalent of nine adult blue whales.
The long-term aim is to bring more bird species nearer to the hides overlooking the lake than ever before, by deepening areas for diving birds and creating milling space for small waders.
And while the developments may have looked dramatic – and very muddy! - at times, we’re already starting to reap some amazing rewards.
Reserve manager John Gowland, who is leading the project, said: “Wader Lake has been a focal point of our wild reserve since we opened in 1975, and is visited by thousands of birds each year.
“In that time, a huge amount of silt had built up and while it does have some benefits, we needed to remove it in order for visitors to experience nature in the way that we wanted.
“During the first phase last September, we removed the silt and dug deeper areas in front of Northumbrian Water hide, at the west end of the lake.
“Water is now retained much more effectively here, even during dry spells, and this, as well as the introduction of natural perching posts, has resulted in some fantastic wildlife highlights.
“We’ve had increased kingfisher sightings and more common tern, redshank and teal (above) regularly seen around the hide, something that was relatively uncommon before the project began.
“Then, just this week, 41 goosander (top of page) were noted roosting near the hide overnight, which is a new site record.”
In November this year, phase 2 of the project saw the middle of Wader Lake excavated to its original depth (above). This means it too can hold water for longer during dry spells and fish populations will become established going forward, supporting birds including grey heron, little egret and kingfisher.
The lower parts of the lake will also retain water better, allowing wading birds like lapwing and avocet to feed in the soft wet mud more during summer.
“The silt from this latest phase was rehomed along the bank of Wader Lake, to the left of Paddy Fleming hide”, added John.
“This has not only created a wider space in which the reserve team can carry out maintenance, but also provided extra habitat and milling space for smaller bird species such as red-listed lapwing.
“The initial works to the west of the lake have been a huge success and as we head into the winter, we are hopeful that visitors such as goosander and goldeneye and diving ducks such as tufted duck and possibly pochard will soon make use of the latest improvements too.”
