LODA, Ill. (WCIA) – The results are in what what could have, and what did not, cause a massive fish kill in Lake Iroquois.
The epa tested the water for pesticides and other runoff.
However, the results showed that’s not what did it.
The field inspector believes it was lake turnover that killed the fish.
That happens when the sediments at the bottom of the lake decrease the oxygen levels in the water, so the fish couldn’t breathe.
It’s a process that can happen periodically.
