They are eager to feed throughout the lake, but tend to concentrate around structure on points, flats and ledges off the river channels. A proven method for catching walleye here is trolling with spinners tipped with live bait, or trolling with long-billed, deep diving crankbaits. However casting live bait, jigs, worms and spoons also works well at times. When the lake freezes over in winter, ice fishing for walleye can be very productive. Use GPS to locate spots you normally fish during other times of the year.
