Jeff,
Since no guides have weighed in, here's my advice. First, if you really want to catch walleye, hire a local guide for a 1/2 day trip. They know the best lakes and locations based on the time of year and conditions of the day.

If you decide to go it alone, here's the general keys: 1) Fish very early (just at sunup) or very late (a few hours prior to sunset to as late as you feel comfortable). If you fish at night, dress for bugs and bring bug repellant. Also some flashlights for baiting and tying on jigs 2) Use "walleye fathead" minnows and 1/16 oz jigs (light green color is my favorite) on 6 lb mono. Keep the minnows alive and fresh by placing a frozen plastic bottle of water in your bait bucket to keep the water cold. Crawlers are next best alternative if you don't want to deal with minnows. Work your jig along the bottom, the walleye will hit it on the drop. If you feel any resistance as you lift your rod, wait a few seconds then give a quick little hookset 3) Fish rock humps and weed edges. Fishing in submerged weed edges along shorelines and pockets of weeds on mid-lake humps are typical walleye summer spots. Tops of mid lake rock humps will generally hold some fish too. You'll need good electronics or GPS to find the humps and rocks. You can buy lake maps on-line or at local bait shops 4) Try Long Lake or Island Lake as Planting Ground has been (IMO) poor for walleye this year. 5) Pick an overcast, breezy day - especially if you fish during the day. These days are better for walleye and not so good for other watersports, so it gives you something to do on an otherwise poor day and the fish won't be spooked by all the boat traffic.

I hope you can catch your first walleye, but this is a bad time of year to try for them! Good luck and please post a reply with your results!
