After wednesdays storm dropped about 12" of snow in our area, I spent some time yesterday renewing my vows with my snowblower and started clearing the BG pond. Time was limited but I managed to get a 10'x80' patch cleared.

Today, the cleared patch is now covered with water, which has iced over somewhat due to the cold temps. I have never seen this happen before. Puzzled as to how this happened, a guy at work provided the answer. After clearing a 20'x100' patch of ice, he watched in amazement as water started percolating up through the ice!!

Have any of you ever had this happen?? I'd like to clear my other pond tomorrow, for fish survival and ice skating but I'm not sure about the safety factor. Both ponds have 9" of clear ice.
