Fish the Bighorn River
Spring (March – May)
- Why Fish It? The trout are hungry after winter and are actively feeding.
- Conditions: Water temperatures rise, leading to increased insect activity.
- Hatches: Blue-winged olives (BWOs), midges, and early-season caddis.
- Tips: Use smaller nymphs and emergers to mimic early-season insects.
Summer (June – August)
- Why Fish It? Warmer weather, abundant hatches, and dry fly action.
- Conditions: Stable flows and clear water make for excellent sight fishing.
- Hatches: PMDs (Pale Morning Duns), caddis, yellow sallies, and terrestrials (hoppers, ants, beetles).
- Tips: Early mornings and evenings are prime times due to heat during mid-day.
Fall (September – November)
- Why Fish It? Less crowded waters, aggressive trout preparing for winter.
- Conditions: Cooler temperatures, stunning autumn scenery.
- Hatches: BWOs, mahogany duns, and streamer action.
- Tips: Streamer fishing can be excellent for targeting trophy browns.
Winter (December – February)
- Why Fish It? Solitude on the river and a chance at large, unpressured trout.
- Conditions: Cold temperatures and lower water levels.
- Hatches: Midges and occasional winter BWOs.
- Tips: Focus on slower, deeper pools with nymphs and small streamers.
