A quick bottle trapping session in the water found a couple of Water Boatmen, a few diving beetles as yet unidentified, a newt and a shed load of leeches. The newt I quickly released without photo, hopefully not too much the worse for wear. The water boatmen seem to have expired. Maybe they are quite delicate beasts despite their size. I have a couple of the diving beetles for determination and a couple of leeches out of ghoulish curiosity. I hoped they could be identified but this may take more capability than I have access to at the moment. Let's see.
I was amazed to find anything given the water looks like some kind of white ghastly chemical soup
