Not an expert on this but Jason is giving sound advice.

I spoke with Mr. Lusk about this at Pondology in October and he said the minimum requirement for my 2 acre pond would be a well/pump that can handle at least 50 Gallons per minute, and running it 24/7 at a volume of at least 35 gallons a minute to keep ahead of evaporation during the summer. I'm in NW Oklahoma so temps would be lower than where you are. You should run it over rocks (or something) before it enters the pond as straight well water is not oxygenated.

There are many more people on the forum with much more expertise in this area. Hopefully you will get more advice from them.
