Yes, I caught it and I suspect it was due to one of the reasons Wayne pointed out. I won't speculate on which one though.
What were you using?
My grandparents had a friend, Injun Joe. He was Maidu, and this was in the 60's before it became incorrect politically. Joe, he ran a D8 Cat, and worked on the Auburn Dam. This is outside of Sacramento, on the American river. This project was halted for various reasons back in the late 70's.
In order to work on various parts of the dam site, they would re-channel the American River. They'd dig the diversion channel, and then when the river flowed that way, they would work in and around the original channel. When they did this, they would fill in the pools in the old channel.
When they filled in the pools, they would have some of the most amazingly stupendously shockingly HUGE catfish flopping around in the mud. I saw a couple of them when I was 12 or 13. He'd bring them home and have them for dinner. For a week

I have never seen such huge catfish since(the ones you caught are pretty big though).
How many people fish with a D8 Cat

This was before power-bait; I think he taped a worm to the front blade of that Cat
Sad thing is, shut down the dam project, and the place is just a construction mess.
