Rapala has given you some great advice!
I'm no expert either but I'll jump in here, generally speaking walleye/sauger/saugeyes are group feeders and will hunt in packs so once you find them it's a mater of what they want to eat. They both are light sensitive and like current/current break areas, but most of all they are just like other fish they have to have forage present. Main forage for the most part are minnows, so anything that mimics them will catch them. Both also love night crawlers and leeches. If I had to go out on any given body of water with just two baits #1 would be jigs with twister tails or tube baits, #2 would be a worm harness tipped with a night crawler or leech. You can almost break the year down to two seasons, shallow gravel/hard bottom flats areas close to deep water during the cold weather low light conditions and deep water structure, points, rock piles, sunken islands and mid lake humps during warmer months with brighter conditions. The also like weeds if available and will be buried inside during bright days and use the edges during low light conditions. Main thing is they like cooler water, low light penetration and current and they are prolific feeders so once you find them they can be fairly easy to catch at times. Hope this helps
Good Luck in your search!
