Kay,
If it helps ya sleep better this weekend, I have been getting phone calls and emails from people everyday since the beginning of march about fish kills. This was definitely the worst year ever in Central Illinois. Here is the kicker though, usually winter fish kills in ponds are catfish and bass, but this year most of them are actually bluegill fish kills and the bluegill are still dying daily from fungus and disease from winter stress.

Your pond will bounce back faster than you can imagine and you can do a few things like transplant some larger sized bluegill to get things rolling even faster.
