I checked thickness on a few lakes today and found up to 2.5″ of ice… but each of the lakes were still 5%-50% open water.
This crazy wind lately isnt letting everything freeze at the same time and there is going to be some significant ice thickness variation for a while.
When you feel you have found enough ice to fish, be SURE to take a chisel and picks along and constantly check the ice thickness! I predict in the next day or two where I was today is going to have 4″ of ice in some areas, and MAYBE a skim coat to 1.5″ in others (sploosh!).
All of this cold weather I think many people are going to assume the ice is uniform once they see people out… Hopefully not too many people take a swim.
