Thanks, guys. The redhorse is similar, but not quite it (and thanks for the tip to look at other variations).
I found this site:
EFISH: The Virtual Aquarium of Virginia Tech
but couldn't even find it there. I wonder if it's a regional variation/strain of something. The vertical markings were prominent enough that you couldn't miss them, and all sizes of them.
Yeah, chubs are weird fish, especially the ones that get the bumps on their heads when they spawn -- the first time I caught one of them, I thought something was wrong with it.
