Eric,I have to look at it as just natures way of thinning the herd,I do wish my ponds had 20 plus ft of depth instead as I dont think this situation would be going on. It is not a huge number and I dont think it will get out of hand.I never thought the chilling effect of "Winter Turnover" would be a killer. You normally hear anything over 18-20 ft in depth is a waste and Im starting to question that in a year like this. Last year I had ice on/off 4 times and the coldest I recorded the bottom water was 36 F and no kill that I was aware of.Every pond and every year is unique.
