Once you have located the edge and fish, the next step is to entice them to bite. Your bait presentation will depend upon the specific edge that you have selected. If the walleyes are directly below and concentrated on a physical edge you can backtroll a livebait rig, jig, or a bottom bouncer rig, keeping the bait among the fish you see on the depthfinder. If you find the fish strung out along the edge, keep the bait moving and they will bite. If they're clumped up in one spot, hover over them and vertically jig them.
Rocks also attract fish, try rocky shorelines.
Rock piles, humps or where rocks and weeds meet or are intermixed, work it over thoroughly with a jig or live bait presentation. Try to determine where fish are holding. Constant bottom contact is essential even though it increases the potential for snags. Use a small jig head with a wide hook gap to deliver the bait in wavy conditions. Leeches are an outstanding rock bait because they can take the pounding.
