They'll have to have a certified weight by a state official in order to confirm, but either way, it's a monster! When I was a kid, I was in a boat with two of my friends and their dad as we left Fisher's Landing marina north of Yuma AZ, heading up the Colorado River to fish and were flagged down by an excited man in a small, but motored aluminum boat. When we pulled aside, he showed us a large Flathead that he'd just caught and was taking it to the marina to be weighed. Turns out is was 47 pounds, becoming the state record at that time. Later that day, at the marina, we boys all got to lift the record fish, but only the brother that was a year older managed to do it. That 47 pound record didn't hold for long as these non-native transplants exploded in size across the state. The largest my dad ever caught was 36 pounds and that was in a drainage canal in the Yuma Valley near my hometown of Somerton in the 80's.
Fishermen always talk about the one that got away but two anglers casting their lines in the Parker area over the weekend didn’t let a potentially record-breaking catch out of their grasp.
