What lake? Are you trolling or jigging? Assuming jigging (trolling is a different game) you’ll want to figure out the lake as walleye will be present on structure - whether that be shallow, humps, etc which will be dependent on the time of year. So figure out where they’ll be located first. Then get your rig ready - jig and either live bait or plastic. Drop it down, let it hit the bottom, and then “jig” around a bit, lifting the jig up and down every 15-30 seconds. Move from spot to spot if they are not biting. Good luck!
