There is still no official cause for a fish kill at a South Knoxville pond, but it's likely that the extreme heat contributed to the deaths.
TWRA dispatchers say they have not been asked to investigate the kill.
However, TWRA water quality biologists say in cases like this one, the cause is often a dissolved oxygen issue common in extreme heat. It occurs frequently in ponds at golf courses where the bottom of the pond gets stirred up by people searching for golf balls. Algae flourishes in the heat in ponds. Algae produces oxygen during the day but uses oxygen at night and can suffocate fish.
