Angling tips

  • found near the surface just after ice goes out in spring, and deeper as the water warms up
  • in early spring, some feed aggressively before dark
  • in the summer, trout hit best in the morning when surface waters are calm
  • use spinners, spoons and plugs with a fly rod, or as summer trolling baits
  • use special deep-water tackle in summer – wire line, lead-core line, downriggers, diving planers
  • try jigging, or still-fishing with large, dead minnows in deep water in summer
  • ice fish with minnows, lake herring or jigs with spoons or bait attached
  • take fish under 10 pounds with a medium-action spinning outfit with 8-pound test line
  • trophy fish, common in northern waters, need stronger line

Common baits

  • spoons, plugs, jigs
  • large live minnows or dead bait
