50 lb flathead pool 14

i went camping this weekend on pool 14 and i went to one of the wingdams to cast crankbaits for bass or walleye before dark i planned on doing catfishing later but when this fish hit my lure it took me two hours two get it in and a mile down river i only had 8lb test it did what ever it wanted. so after i caught i was catfished out and i never even went catfishin lol. i photoed and released i will try to post pic later this week this thing was a tank unreal by far my biggest fish
