i posted yesterday. lake near me typical of lakes and ponds central and east of ct river - blown out. no ice- winds posting 30 to 40 mph. lots of white water.
I agree that the water is being cooled to near freezing throughout the water column in shallow lakes.They will probably lock right up when the wind dies. It cant happen soon enough for me. As an FYI, maximum density of water is at 39.2F.
I stand corrected, memory getting dim on detail issues. This makes sense as the thermal mass of water could not have formed 8" on Gardner overnight if the difference was only two degrees instead of 7 degrees.
I cautionary note, if you will be venturing onto flash frozen ice you will not be able to tell how thick the ice is and beware of spring water spots where the ice will be thinner. That day on Gardner lake the 8" ice was completely invisible. With full sunshine the experience was surreal. We were walking on glass, water absolutely clear, every detail on the bottom clear as we walked over deeper water. We chopped at the ice with a spud every 25 feet or so to confirm the ice was safe on the way out.
My nephew's son has become an avid fisherman, and I was going to take him and his friend ice fishing for the first time tommorrow before he goes back to college on Sunday. We cancelled till I don't know when. I think he would of liked it.
