I fished for Walleye in Canada several times.
It was in a Shallow lake though. Some depths to 50 feet but we normall fished for them where we could cast to the shallows and retrive slowly to the deep.
We used 1/4 Oz white lead head jigs, with a big Red and white Eyeball on the Head.
Put a white curly tail grub squeezed up onto the hook. Bite off the head of the White Grub to shorten it a bit.
Make it grub around along the bottom like a feeding Fish or a pile worm.
The other guy who did well used a small spinner/jig called a Road Runner. He had all Chartruse Bodies.
If your gonna drift, you have to keep that bait moving to attract any fish.
You'll catch Crappie and Bass with that big grub. Check your reg's.
