Full table →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.
- ·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.
