Fishing Tips

  • ·Trout hold in the deepest, coolest water during summer. Early morning stillwater fishing or bottom rigs near spring seeps is productive.
  • ·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.
