Theo, last time that I kept track, temps in all depths never exceeded 72f. My fish license only allows rainbows, brook, brown and artic char. I have experimented with bottom aeration intervals of 24/7 and also night time operation only or when air temps were lower than water temps. I'm sure local native species would survive, i.e. yellow perch as they are common in small shallow water bodies around here.
When my pond was dug it was 15 feet deep across the entire bottom, I have spoke to others with trout in my area, and the successfull ones are usually 25 feet deep.
Cecil, the wells here only produce about 5gpm. I had to drill a new one for my house a couple of years ago and that's the best gpm that I could get, it also cost $10,000 for 200 feet.
