My garden pond yesterday
Judging by the amount of traffic on the blog, people are worried about their ponds freezing up.
My main message is – don’t worry too much!
I’ll post some detailed guidance later.
In the meantime, the (terrible) picture below probably goes some way to explaining why ponds can be fine in the cold.
The green areas below the ice are a mixture of mosses growing underwater and algae on the bottom of the pond. Both are probably producing oxygen, which is probably what's keeping levels high beneath the ice.

I have a large pond and, probably due to the extended freeze, has a large number of dead frogs, newts and dragonfly larvae. There is no sign of trauma or disease, just lots of bodies which is sad.

Could you be the same Dave Horstead who lodged with Frank and me at Latchmere Rd in Battersea. Would love to hear from you if this is so. I dont have the same problem with pond though, as we live in Australia now.
