Thanks for the replies. I had never witnessed this before. Its interesting to me that even though the snow is very light, 12" is enough to cause this. Hopefully I can achieve some snow removal from the big pond later today, enough to ward off a fish kill.
Side note: Bill, my friend did mention that as he was clearing the ice, cracks were occuring. This must of been the avenue for the water seeping up "through" the ice. This is not pond related but a local mall, with a two tier parking area, had a section of the top tier collapse after the snow removal contractor piled too much snow in one area. Thankfully only a couple of cars were damaged and no one was hurt/killed.
