Thanks guys. We've had some of that wind. Rarely is it more than slightly breezy here. 10 mph is something to really comment on. Rod, without measuring the temp profile of the whole column, do we safely assume the pond is not turning over twice per day, but that the surface water is going from 32 degrees up into the 50s and is more or less sitting on top of the major mass of pond water that's not fluctuating much at all? That would provide for a nearly constant refuge for the fishes.
