Fishing Tips

  • ·Musky fishing is best in early morning and evening. Work weedlines and structural transitions with large bucktails or soft swimbaits.
  • ·Wisconsin musky season typically opens the first Saturday in May. The fall bite (September–October) is peak for trophy fish.
  • ·Walleye feed most actively at dawn and dusk. Jig along deep structural breaks or troll crankbaits along weedlines at 6–8 ft depth.
  • ·Night fishing under a full moon can produce excellent walleye results from late June through August.
  • ·Largemouth bass relate to shallow structure. Work topwater lures at dawn in summer, then switch to soft plastics rigged weedless around lily pads and fallen wood.
  • ·Bluegill and crappie stack up in 8–15 ft of water near weedlines. Small jigs tipped with a waxworm are hard to beat.
  • ·Panfish are often excellent for kids and beginners — look for them around any dock or submerged brush piles.
