Angling tips

  • found near overhanging trees, submerged wood, rocky points and shoals
  • inland-lake brook trout are most active during spring and fall
  • river brook trout stay in cold pools at the base of falls and rapids through the summer, spread out during the spring and fall
  • worms and other natural baits are preferred during high-water periods
  • use a flyrod and flies as water temperature rises, and trout move from deep pools into riffles in search of insects
  • use a light-action 7-foot rod and a spinning reel holding 4 to 8-pound test

Common baits

  • small minnow-imitating plugs
  • spoons, jigs, spinners
  • artificial flies
  • worms, minnows, leeches, insects
