Pond Boss Forums STOCKING A NEW POND Types of fish to choose how small can a fish pond be?

Sorry, I did not ask the question clearly enough. If I know the flow rate out of the pipe from an artesian well, can I approximate the maximum pond size (and shape) such that I could keep trout year round (small enough to keep the temp down midsummer)? I can figure out the flow rate mid summer as you suggested, but do not know what a "safe" maximum pond size might be. I understand that it is heat gain from the air minus heat loss from the input water and surrounding ground, but do not know a practical way to calculate the actual pond size.
