you might start by talkin' w/ the bait shops about where they've been catching them, on what, how deep. keep an eye on which side of the lake the wind's been blowin on for a few days, tends to attract them. get set up w/ some 2 hook walleye spinner crawler harnesses and some bottom bouncers, some crankbaits like shad raps and some snap-on weights for long lining, find main lake points and start trolling. if you can find main lake flats fish them especially at night. if the lake produces electricity, troll the outlets at night 50-70 feet down. troll rip rap at night during spawning time. good luck good eating.
