Walleye tend to travel near the bottom in areas with some current but not too much current. So get your bait down to them such as jigs or minnows or both. Tipping your jig with live bait adds sent, taste and a bit of bulk. Walleye lightly suck in the bait, so be aware for light taps. If problem hooking walleye which seem to get parts of your minnows, add a stinger hook to the tail.
Hooking minnow through mouth and out top of head works good.
If you use leeches, hook them through the sucker and they will be lively all day. The bottom bouncer type weight rigs work good to keep bait down and out of trouble in rock. These cool season hotspots include dams, wingdams, underwater obstructions, irregular riprap banks, side pockets, banks eddies and any current breaks. Other good spots to fish are feeder streams during spring. If you try crankbaits in spring, use colors of silver and chartreuse.
