Find wood at Petenwell Flowage and you'll find fish. That's according to icefishing expert and author Tom Gruenwald, who considers Petenwell one of the state's best winter walleye fisheries. The 35-foot-deep reservoir is full of stumps and timber debris. "Use tip-ups and dangle a minnow; tip-ups outperform jigging ten to one," Gruenwald says. "If your tip-ups are getting caught on wood, you're in a good place. But pull them up fast when you get a bite." The walleye limit is five per day with a 15-inch minimum length. Gruenwald says some of the bigger walleyes will reach 10 pounds. From Wisconsin Rapids, take Highway 13 south to county roads surrounding Petenwell Flowage. There is lake access at Petenwell County Park on County Road Z. Contact: Wisconsin Department of Natural Resources (608-267-7517).
