Was out at the local watershed and saw this.

Catfish

Yea that's a catfish

Nessie!

LOL...The thick blue fin looked like a blue cat but I swear that thing had yellow stripes.

Jaws

Chupacabra.......or just a cat.

LMAO!!!

I think it's a Carp man. I have seen this before too, and I chased it down with a pattle boat and saw a school of big carp swimming together.

It had a thick blue fin.

That was my first thought but the fin was the wrong color to be a carp.

It's a grass carp, they do that in the lakes and ponds around here all the time. I love it when they do that cause then I can sneak up close enough to fling an arrow at them. I've never seen a catfish cruise the surface close enough that their tail was out of the water and their mouth and whiskers not be out of the water too. That would also explain the blueish green color of the tail.

Imma fix me up some jugs to set out and see if that catches anything. And if not then imma fish the heck outta it to try to catch this monster. Hes gotta be hungry for something.

At the angle that fish appears to be swimming I would think a catfish's dorsal would be out of the water too since they can't lay it down. If that's the case setting juglines would be a waste of time.

That's a large grass carp. Got them in the lake I fish in. I didnt think carp had such dark fins either, but I paddled up on them the other day after being curious just like you, and in the clear water I could see them quite well before they spooked off.

Grass carp was my immediate thought. The tails on the big ones can turn a dark gray/blue color.
