Dave Harrell posted the picture of him holding the massive turtle at Eufaula Lake to the Oklahoma Department of Wildlife Conservation's Facebook page.
In the description, he said he was fishing for catfish on Sunday with a friend when he caught the big beast. He said he snagged it on a rod and reel and then pulled him to the boat for pictures.
After snapping a few memories, he released the big turtle back to the lake. He said in the post that it's the biggest one he's ever seen.
He posted the above picture to the ODWC's Facebook page where it's already been shared more than 4,000 times.
