I typically see the same type thing on my larger pond which is not spring fed. I currently have 4 inches of solid ice with 1.5 inches of thick slush-snow and 1 inch of regular snow on top. Yesterdays accumulation of heavy wet snow has caused water to move on top of the ice and make most of the snow water soaked. About in the center of the pond there is a round 10" to 14" open water hole. I assume this is where most of the water is moving out and on top of the ice. I have seen these clear, ice covered, round holes during previous years after they have frozen closed. Water movement through this present open hole has enlarged the hole size during the last 24 hrs. I am curious to see if all snow becomes water soaked before the open hole freezes solid during cold temps predicted for the next few days.
