One of the toughest bites walleye anglers face is immediately after a weather front passes. That’s right now when the weather is ice cold. This cold weather makes walleye sink in the depths and hug tight to the bottom. The key is to concentrate on the deep holes in the river. The more defined structure helps these sluggish fish hang without using too much energy. Use some heavier trolling sinkers to slow down the presentation. The longer you hang in front of the walleye’s face the more likely you’ll get a strike.
