I’m not sure if you have seen the videos Roger, but there is actual proof of a sturgeon in Hagg, looks to be in the neighborhood of five to six feet. Right up on the dam, with panning shots of the surrounding area, enough to tell where it was shot. Several different people have seen it, and got still shots and at least two videos I have seen. It might be a solo fish, but they live a long time.
And for the purpose of clarity, bullheads ARE cats, just not channel cats. Same family, different species, like smallies and largemouth, for example. You weren’t wrong to call them cats.
