I've put a sketch of my pond here. The current pond is in blue and the proposed new water is in green. I have approximate water depths written in and the aerator and fountain are in red designated with both and "A" and a "F".
Hopefully you can see what I'm talking about as far as creating a cold sink to store cold water. Not sure if it will work, if it doesn't I'll still have a bigger pond
By the way, I can't really remember the exact length and width as I have written in. I do know that I measured it at 1/10 acre when it was done. It's just a shade larger than that.
