They're back.

Mum, dad and the five babes are all safely back.
I have to say the newly cleaned water looks as brackish as it ever did, and I swear I can see a tide-mark on the white swans. However, they don't appear to be any worse for wear, and if anything, seem more tolerant of the ducks who are now allowed to share the pond.

All we need now is for the sun to come out.
