First year for me watching a pond thru the winter. For those folks that may have never seen thick ice on a pond with aeration, the water level where the aerator sits is in the bottom of a big ice bowl with sides sloping up to the actual pond level. The bowl just keeps getting deeper and the aerator hole just keeps getting smaller as the ice thickens even more. Probably have a good 16 inches now.
Bill, if that's what it looks like then I think you are loosing water from your pond.............
