I've done some digging on past threads about keeping trout in small ponds and I gather a well is probably necessary. My pond is about an 1/8 acre and the deepest point is about 8.5 ft deep. I've been using black dye and took bottom temps yesterday and it was 66.7 degrees while air temps were about 90. Is it at all possible to aerator this enough to make the pond inhabitable for trout year round? I was also looking at possibly constructing a pond chiller and putting in a water fall. I'm guessing that drilling a well and upgrading my aeration would be the best route. Does anyone with experience have recommendations?
