BZ -- as I'm sure you know, winter started a little early and with snow this past fall. That often is a recipe for disaster in our ponds. When ice goes on early and cloudy, like this year, and then snow covers the ice, we often are in for trouble. However, this winter was mild for most of the months, and the snow cover cleared pretty well. Then, after a mostly mild winter, we had a cool March, and extended our ice season. Ice-out didn�t occur until the end of March/beginning of April. So, I was quite relieved when we had no winterkills in our area ponds that we manage.
