Sorry it didn't work out Waterloo. My place used to be a commercial trout operation (trout haven). The pond is about a third of an acre, and about 10' deep. Well water from two 1.5hp sand point pumps ran most of the summer. The well water would be sprayed into the air over the pond to keep the temp down and aerated. The pond will fill up to a weir, where it would spill out, thus maintaining a constant depth. There was a constant exchange with fresh cool aerated water. The trout did great all summer. I think the well water was about 58 deg. Well, this is all in the past. Can you imagine running well pumps all summer and the electric bill.
Today, we have LMB, BG, CC, FH's, and White Crappie. We run an aerator, and feed pellets. Oh, we have some leaches, bull frogs, garter snakes, box turtles, cattails, reeds, a little bit of algea, arrow head, pond lillies, to name a few species. All is well.
Waterloo, based upon the trout operation previously run in my pond, I would say you would need a whole lot more cool water from wells to keep trout from being stressed. The water also needs to be aerated in some fashion. Trout are a cold water species and that can't be changed. Again, sorry about the loss.
