Concerns about water temps/O2 saturation in a shallow, non aerated pond, re: TM? I've not measured either, but I am sure we see high 70s water temps?
Since the pond is near your house, I think the addition of aeration could be a great (and cost effective) benefit to your pond - especially if your pond is near the carrying capacity limit due to all of the carp and other trash fish.
You might search the archives and read a few of the good aeration threads.
