I also have a 60 acre lake and was told it was a waste of money to air rate it. Would need to turn all the water to do any good. Large lakes hold more DO due to not all the water has fish in it. So it is a storage bank of DO. But if you have a lot of wood chips or plants rotting that also takes up a lot of oxygen. Having just a small open hole in the ice could attract a lot of geese, could produce a lot of nitrogen and have weed problems the following year. I am not an expert so maybe someone with experience will correct me if I am wrong.
Also if 1 hole in the ice would attack some fish I sure would like to know and welcome to the forum there is a lot to be learned from the people here.
