Thanks for the clear reply! I thought you had said that one windmill was working and a hole was open most of the winter. How do you assume all the fish are dead if you maintained a hole all winter, all be it a small one?

I guess we find out in a few weeks.

I'd love to see more pictures of your salamanders, leeches, crayfish and other critters and hope you find them to have survived somehow.

Otherwise, next year for sure!
