IMO Fish have to feed regardless so I think it may just change the areas you should target. High and low water levels make it easier to target fish. The in between stages can make it more work. I still have a lot to learn though plus I don't target cats very often. I would imagine flooded shorelines next to fast current in high water are prime spots to find cats foraging/hunting. Shallow or summer pool levels deep holes with highly oxygenated water and next to a flat might be good for flatheads. Most of the channel cats seem to sit in the channel in moderate current. :lol: Again, I never target cats and only started river fishing around 4 years ago so I could be way off. Hopefully some others will add their two cents.
