How to fish it · for Lake Trout
When
Nymphing can work through most of the day.
Where
Cover mixed depths.
Method
Start with tight-line nymphs and adjust if fish rise or drift higher.
Kit
9 ft #4 rod, floating line, 12 ft tapered leader to 4–5 lb fluoro tippet.
Why this works
Excellent — water temperature is working for you, but insect activity is the limiting factor today.
Likely species
Mayflies
  • Iron BlueMost likely
    #16–18 · Dun
    Cold, grey day — the dun sits long. Good dry-fly water.
  • Large dark oliveAlso possible
    #14–16 · Emerger
    Dead-drift the emerger — it's sitting in the film.
  • Green drakeAlso possible
    #8–10 · Dun
    Duns are up — the Spent Gnat spinners fall at dusk.
  • Blue-winged oliveAlso possible
    #16–18 · Dun
    Duns are up; a sherry spinner fall may follow.
Caddisflies
  • GrannomMost likely
    #14–16 · Pupa
    Pupa first, then dries as the adults come off.
  • Satin sedgeAlso possible
    #12–14 · Egg-laying
    Skitter it at dusk — this one's fished, not dead-drifted.
