Folks - thank you all for your feedback and Bill - that is a good point about the jaw. I was mostly determining they were flatheads based on the color and my assumption that all Bullheads were small so it had to be one of the big 3. Looks like I no longer need to worry about Flats eating all of our fish and now I need to shift my focus to seeing if any of these Bullheads will break a state record =) I may still reach out to the forum with questions as I'm removing old muck and leaves from my shoreline, working on making an area for bream beds, and I'm creating some fish habitats using various ideas (milkcrate structures for fry, pallet towers, rock piles, floating wetlands, etc) so that I can do my part to keep this body of water healthy.
Thanks,
LTL
