Mud bottom and 12-18 FOW near an inlet that goes to about 4-6FOW near spring.
Here at least, they head into shallows to spawn, lil narrow inflows and reeds.
I use a small buckshot rattle spoon tipped with frozen shiner heads. That's all I ever use. Even mid winter
I've noticed though, a specific technique that works well for me, and finding it was due to electronics.
The lure brings in fish, no doubt about it. You'll catch a few fishing it normally. But dropping the lure to bottom, rest, then rip it up 2 or 3 feet produces a frenzy of bites
That rip up is sometimes a true rip, sometimes it's a little slower
But almost all the bites come of the chase up
