I looked on line a bit more and came up with a couple of thoughts-

if there was a lot of runoff due to rain, it is possible that toxic
stuff got washed intot he pond. Probably not likely, but a thought.
With the insects etc also effected, I have to wonder if someone was
doing aerial spraying of pesticides before the storm. Again, seems
pretty far fetched unless you saw the crop dusting planes before the

A large influx of rain may have rapidly lowered the temperature in a
small pond, which may have been enough to kill the fish.

Alternately, a large rain fall may have caused de-stratification of a
deeper pond, which can cause de-oxygenated water to mix with more
oxygenated water, reducing the overall oxygen level, killing the fish.
