LOUISVILLE, Tenn. (WVLT) -- Environmental investigators are trying to figure out what caused thousands of fish to wash up on shore over the weekend in Blount County.
TWRA says people on Rivers Edge Road in Louisville started finding fish on Friday. Fish were not observed struggling as one would expect during a dissolve oxygen event, they just showed up dead. The fish could have died in a very restricted area and have been dispersed by wind and water currents.
"There's just so many factors that could have caused this. Environmental just doesn't seem to be one of those options," said Jim Negus, TWRA.
Negus estimates that between 2,000-4,000 fish were killed and as many as 15 species were affected.
Negus says the time period between when the fish started dying and his teams were call will make it difficult to figure out what happened.
"It's important to get to them while they are dying in order to take water samples of that event. Right now that water's probably passed through here," said Negus.
Negus says the fish stretch over a 2 mile are on the Little River. He says TDEC and TVA have both been called to help investigate.
