Its been a pretty rough winter this year. We have been iced over on the pond for quite a while now and for about a month the pond was snow covered. I am pretty stressed about the RES. Anybody have any thoughts about their survivability in the winter. I was told in new BOW that winter kill was pretty rare, but I am still a rook. The pond is very lightly stocked so I am thinking the oxygen reservoir should have been pretty large for the fish in it.
