Jigging spoons work great for walleye.  Fish them deep in the same places you would jig for walleye and jig these spoons up with an erratic jig and fall retrieve.  Walleye will usually hit these baits on the fall, so be ready after you jig the bait.  With jigging spoons, that erratic snap jigging technique is usually the best way to catch walleye on them.  Some anglers do tip their jigging spoons with live bait as well.

Trolling spoons will work well, although, most walleye anglers prefer to use spinner rigs and crankbaits.  You can have a lot of success if you can get the spoons to the correct depths that the walleye are feeding at.  Some anglers will combine bottom bouncers will spoons to make sure they get their spoons near the bottom.  You can also troll spoons at different depths throughout the water column for suspended walleye.  The most successful anglers will have several fishing rods out with spoons at various depths so they can target suspended walleye as well as fish on the bottom.  Trolling speeds can vary from 1.8 to 3 mph, however, most anglers would probably be somewhere in the middle.  When the walleye are active, you can troll a little bit faster and expect to catch some nice fish.  When the walleye are finicky, you need to slow it down and keep your baits as close to the fish as possible.
