The average air temperature in RedSpruce's area is very probably lower than that of fishNYfun in NY. With warmer air temps more flow of cooler water becomes more imporatant for trout survival. In the northern areas, thick ice without open water in trout ponds becomes an important management consderation to prevent winter kill from too low of dissolved oxygen (DO).
Excellent Point Bill. I usually run a little air on an edge of the pond to keep some water open to prevent that. In fact i do that in all of the ponds I have fish in. (Drain and refill production ponds).
