The aeration was the key in keeping the trout alive, the pond depth was key in keeping some water cool enough for them. Without the aeration the O2 levels in the deeper water would not be high enough to support the trout, or any other fish for that matter if you measured the O2 levels at the bottom. I have a YSI ODO with a 10 meter probe.
In a pond that was 10' deep max, trout stayed alive in 79°F-80°F water due to the bottom aeration and the surface agitator pushing the O2 levels to saturation or higher. Unfortunately the water temp climbed even higher and they didn't make it. (@ 80°F the O2 was still 7.7 mg/l)
