Not looking for flathead hotspots… I’m wondering about where they are not. (Or not a lot.)
How come the upper Miss. isn’t known for flatheads? Upper St Croix?? Is there a difference in habitat? Sure, the northern stretches of these rivers are not as deep, but there are plenty of holes, bends, and logjams… plenty of baitfish to feed on.
Everyone fishes Pool 2 on down the line for flatheads. Yet Pool 1 has much of the same characteristics (depth, flow, species, lock & dam, etc.) and hardly anybody fishes for flathead there. Why?
