Just guessing Clear Lake or Hamilton
42 plus from northern Indiana that was picked up last Sunday. Notice the regenerated scales centered between the dorsal and anal fin. I see that a lot on northerns.
If you fish for them shortly after they spawn they look like they have been in a war. They beat the crap out of each other when spawning and I would bet that is why you see so many with regenerated scales. I have caught some ugly looking fish with battle scars in the spring time.
