Your gonna want a lure that is used for what is a called a search bait. It's a bait that you can cover a lot of area with in order to try and locate fish. A good bait to try is Rapala's X-Rap in a natural bait fish color. You can reel it down to any depth you want and it suspends there. It goes down about a foot for every second of reeling. Try a size #10 for a search bait and a size #8 as a follow up if you start getting hits.

I like to throw a Smithwick Rogue. The trick is getting it to perfectly suspend. I don't want the bait to float or sink. I put lead stickers on them to acheive neautral bouyancy. The X-rap is alright, but the eyes come out and I've had several break on fish. Use a color to match the baitfish on your lake. Can't go wrong with black and silver it seems.

I would use a Gary Yamamoto Senko worm without a weight. I like darker colors with black being my favorite. With out a weight these worms will fall very slowly and have somewhat of a wiggle to them. I started fishing them about 5 years ago and i have yet to find anything that fishes like they do. Downsides are that they are expensive and they tear easily.

Senko baits are great this time of year, I also am a big fan of chrome rattletraps. I have had great success this time of year with these baits

In Michigan we occasionally catch them through the ice, with suckers.
