The water levels in Shepherdsville were at their highest on Sunday, WLKY reported.

Fegett estimated that the catfish weighed close to 40 pounds, but Watkins said it was more than 50 pounds and possibly as much as 60.
"That scale we had wasn't no good," Watkins told WDRB. "We had a 50-pound digital scale from Walmart, but it just -- it maxed out. It wouldn't go no higher."
We’ll never know for sure. Fegett said Watkins let the catfish go.
The fish had been tied to Watkins’ porch, WDRB reported, but there had never been plans for a fish fry.
"We don't eat none of them big ones," Watkins told WDRB.
Meanwhile, Watkins’ daughter, Heather Watkins Colvin, posted photos of her father’s home, ruefully noting that it “Doesn’t look like we’ll be getting in Dad’s pool anytime soon.”
