Fishing Tips for Miller Lake lamprey

  • Use a light‑tackle setup and fish near the lake bottom where lampreys rest during the day.
  • Target during the spawning run in late spring; they become more active and come into shallower waters.
  • Use small live bait such as minnows or nightcrawlers; lampreys are attracted to movement and scent.
  • Fish quietly and use a slow, subtle retrieve; sudden splashes can scare them away.
