The DNR is investigating a fish kill in Fayette County.
Their staff spent Wednesday in West Union working to track down the cause. The fish kill was reported earlier that morning, but residents say they first saw dead fish on Tuesday afternoon.
The DNR started finding dead brown trout below a storm water drain that flows into Otter Creek. The fish kill extended at least a mile downstream. It appears to have affected only the naturally reproducing trout, not other fish species which were swimming around in the creek. The DNR says trout are more sensitive to temperature changes and chemicals.
DNR field tests did not point to a definitive cause of death. The investigation is ongoing.
