A difficult site to check nowadays since the sludge beds were discontinued. The habitat is still very good even though it's overgrown including marsh and a phragmites bed - you just can't see anything. !
A big plus was the filter beds with anything up to 400 (impossible to count)!! House Martins and 100+ Swallows and c50 Swifts. They were all massing around the beds, an amazing site which was probably due to the overcast and muggy conditions and mist and drizzle on higher ground and loads of insects hatching. No Sand Martins found.
Chiff-chaff and Blackcap around and 100+ Carrion Crows on and around the filter beds and 1 Grey Heron and a pair of Grey Wagtails on the river.
