- ·Northern pike are ambush predators — target weed edges, fallen timber, and points with large spoons or swimbaits.
- ·Spring pike fishing (ice-out through June) can be outstanding as they move into shallow, warming bays to spawn.
- ·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.
