timK Whenever the water is at or below 50F and the pond does not have lots of dead muck bottom layer I would not run the aeration. At 50F the wind can pretty well mix the pond. If you want to be on the safe side you could run the aerator in winter 1 hr per day. Plus as Theo said the water at 50F holds a lot more DO. At 50F DO consumption by bacteria, phytoplankton (nite) and other life forms is a lot slower and less per day compared to water above 65F-70F.
