A guy I used to know had a pond that extended under a deck of his house. It wasn't much more than 1/4 acre, and maybe ten feet deep. It was fed by a spring that I would estimate flowed at least about 100-200 gallons/minute at about 56-58 degrees F. He had several huge (to me) rainbow trout in there, maybe 10-15 pounds. Cool water, and flowing water, seems to be the key. He fed them trout pellets off the deck.
