Thanks to Mike Wallen of Bucks Bird Club for this news, written on 6th September:
For those not already aware there are significant developments at Willen and we are going to get some waders !!
The North lake has a problem with a valve on the sluice; to repair it they’ve had to dig down a way and have created a large breach to the lake. They have tried to dam it but the dam has collapsed.
So far the South lake has dropped by about half a metre and mud is developing around the edge! This is because the south lake is draining into the North lake in the south-east corner. However the water is leaving the North lake much quicker than it’s coming in, and 30% at least of the North lake area is now mud!! I’d estimate the water level there to be down well over a metre already.
This morning (6th) it has already attracted a Dunlin, then 2 x Black-tailed Godwit flew in, shortly afterwards another 2 x Black-tailed Godwit flew in.
Over the next week (and hopefully longer) this could be seriously good for waders.
