February on the Bighorn rewards the angler who doesn't mind cold fingers. The river is fishing well and the crowds are nonexistent — just you, your guide, and miles of blue ribbon water.
Winter fishing on the Bighorn remains effective with trout lying deep. Key tactics include deep nymphing and slow streamers, focusing on stealth and depth due to cold conditions. Rainbows and browns are selective but catchable for the prepared angler.
Midges are emerging every day and are the most reliable dry fly opportunity of the winter months. On calm, warmer afternoons watch for subtle surface activity in the softer water — those moments are worth waiting for.
What's Working — February
Nymphs: Sowbug #16, Orange Scud #16, Zebra Midge #18-20, Black Zebra Midge #20, Top Secret Midge #20
Dries: CDC Midge on calm afternoons in softer water
Streamers: Olive Woolly Bugger #6, slow stripped near structure — not consistent but worth a few casts each morning
Target: Deep runs and slower buckets — mid-morning to afternoon is the best window as the water warms slightly
