Winter Fly Fishing Report: Gunnison River's Black Canyon Insights

The canyon is settling into its autumn groove: light is low, water is cool and clear, and the trout have shifted out of high-summer routines into deeper runs and tighter seams. The walls of the canyon cast long shadows by noon, so choose your spots with care.
Wildfire smoke from the recent South Rim fire has put a haze over the rim, but the gorge itself remains open — still, check access before you roll in. National Park Service+1

Pro Rig of the Week

Use a 10′ 5× floating leader to a #16 Parachute Adams. Tie 18″ of 6× to a #20 Zebra Midge underneath. Start with the dry and drift it into tight seams. If fish stay deep, remove the dry and let the midge do the work — you’ve instantly converted to a stealth-nymph rig with minimal change. Short casts, subtle mends, and tight presentation to the seam edge are key in this canyon setting.

Top Flies for the Month

• Dry Fly: Parachute Adams #16 — for suspecting BWO activity in shaded runs.
• Nymph: Two Bit Hooker #18 — deep runs hold fish now; weight and drift matter.
• Streamer: Olive Sculpzilla #6 — when light fades and fish move into structure.

Tips Fly Fishing on the Gunnison (Black Canyon)

• Seasonal Tip: The canyon fish are transitioning into fall behavior — slower water, deeper shelves, and less surface activity. Adjust tactics accordingly.
• Dry Fly: Look for soft light along seams; the dry drift must be near slack water or eddy margins.
• Nymphing: Use weight; fish are deeper and in slower water. Long drifts through seams and tails will pay off.
• Streamer Fishing: Use when light is gone or cloud cover rolls in; target undercut banks and shelf drop-offs.

Access Points

1. East Portal Road — remote but high reward, float or hike-in for the real canyon experience. ⭐⭐⭐⭐⭐
2. Pleasure Park take-out — accessible, fewer steps in, good for wade/float transition. ⭐⭐⭐⭐☆
3. Gunnison Gorge trail access — more challenging, less crowd-ed, gives solitude in the canyon. ⭐⭐⭐☆☆

Local Regulations and Landowner Notes

Artificial flies or lures only; all rainbow trout are catch-and-release in the national park section. Be sure to respect posted signs and private land closures.
