The water in the ponds and outdoor tanks never went over 88F. There were no

I don't recall just what my highest water temperature was, but it was
close to 90 here too. I kept air going and changed two water flow
inlets for more water friction. I also thinned the herd in June just
before the heat really set in. I lost two small koi about 4 inches
long that jumped out of a 160 gallon pond. Pretty sure it wasn't heat
related.
