Brook Trout


Colorful char species with worm-like vermiculations on the back and bright orange bellies in fall. Introduced to the Rockies and thriving in many cold streams and alpine lakes.

Where to Catch: Cool, clear creeks, beaver ponds, and high-elevation lakes; prefers shaded pools, undercut banks, and inlets/outlets with steady flow.

Best Time to Fish: Late spring through early fall when insect activity is high and water temps remain cool.

Season Activity
Spring (Mar–May) Good in late spring as ice recedes; small nymphs, leeches, and attractor dries in softer water.
Summer (Jun–Aug) Excellent; active surface feeders on caddis, mayflies, and terrestrials; dusk and dawn prime times.
Fall (Sep–Nov) Very good pre-spawn; bright colors; fish aggressively strike streamers and large attractors.
Winter (Dec–Feb) Limited; occasional ice fishing opportunities in stocked lakes with small jigs tipped with bait.

Peak Season: Late June–August.

Tackle & Tips
Lures: Small spinners (#0–#1), micro spoons, and 1–2″ minnow plugs.
Bait: Worms, salmon eggs, or artificial flies (check local bait regs).
Leaders: 4–6 lb fluorocarbon for stealth; lighter in clear, still waters.
Gear: 3–5 wt fly rods with floating lines; ultralight spinning gear for small creeks and ponds.
