Many lure or bait works at the whirlpool. As long as you can bring your presentation get down close to the bottom without getting snagged. Here are some lures I had used with success.
1. 3/4 oz Jig heads with black, white or pink grub
2. Heavy small spoon
3. Crank baits, Rattler.
3. Streamers
4. Spinners
5, Roe. Power Minnow. Live minnow
6. mini bucktails.
6. Kwikfish
If the water is too clear, 6+ ft visibility, it is tougher to fish it. Normally best from twilight till 10am in the morning.
Slow down one's presentaiton , the slower the better.
