Gunnison Gorge NCA — Fishing Report for April 26, 2026

Quick Stats

Flow: 597 CFS | Trend: Stable | Fishability: Good | Weather: Showers and thunderstorms, high 56°F

The Bite

Today's weather is the story. Showers and thunderstorms are in the forecast through the afternoon, and while that sounds like a reason to stay home, the Gorge's canyon microclimate often turns overcast, unsettled days into some of the best dry fly fishing of the year. BWOs and midges thrive under low light and cloud cover — expect the hatch window to open somewhere between noon and 2 PM and potentially run long into the afternoon. If the rain holds off during that window, fish should be up and looking.

Skwala stoneflies are also worth your attention today. On warmer midday stretches — even with intermittent showers — these big early-season bugs can draw aggressive surface takes. They're one of the first large-insect dry fly opportunities of the spring, and Gorge fish aren't subtle about eating them. Keep an eye on the riffles and slower water along the canyon walls for any adult activity.

At 597 CFS, flows are stable and sitting right at the upper end of the ideal range. Crystal Dam's regulation has kept the transition smooth — this is not runoff water. It's fishable, though wading requires care in the deeper slots. A drift boat or raft covers far more water and puts you in position to chase the hatch as it moves through each run. With snowpack at just 12% of normal basin-wide, runoff this year is expected to be mild and short — the Gorge may stay in prime shape well into May, so this float season could be a long one.

What to Fish

• Skwala Dry #8-10 — Fish this on point during midday warmth; let it ride the seam naturally along the canyon walls and slower edges
• Parachute BWO #18-20 — Primary dry fly once the hatch fires; position below riffles and let it ride drag-free through rising fish
• RS2 (olive) #20 — Fished 16-20" below a Skwala or Chubby Chernobyl as a dropper; deadly during the BWO emergence
• Juju Baetis #20 — Alternate BWO dropper; slightly more profile than the RS2, good in moderate current
• Pat's Rubber Legs #4-6 — Anchor fly for a double-nymph rig in the deep runs; covers stonefly and attractor bases all day
• San Juan Worm (red or wine) #12-14 — Effective all day near the bottom, especially if rain muddies the edges

Tactics & Rigging

For the dry-dropper setup, rig a Skwala Dry or Chubby Chernobyl (tan) #8 on point — it's buoyant enough to carry a small beadhead — with an RS2 or Juju Baetis dropped 18-20" below on 5X fluorocarbon. This covers both the stonefly and BWO windows simultaneously and is the right call from late morning through the hatch. When the BWO emergence gets dense and fish are visibly rising, drop down to a straight Parachute BWO or Sparkle Dun on 5X or 6X and focus on drag-free presentations through the feeding lanes.

For nymphing the deep runs — especially early in the morning before the hatch — lead with a Pat's Rubber Legs on point and trail a Pheasant Tail or Black Stonefly Nymph 14-16" above on a tight-line or indicator rig. Fish the seams and deeper slots at the tail of pools where big browns hold. Wade anglers at Chukar Trail should work the water methodically and be in position below a riffle before noon — when the bugs start, you want to be ready, not scrambling.

Access & Logistics

Chukar Trail (the most accessible rim-to-river route) is a steep 1.5-mile hike — trail conditions may be slick today given the rain. Wear appropriate footwear and check BLM conditions before heading down. Float trips launching today should monitor afternoon thunderstorm timing closely; lightning in the canyon is a serious hazard. Day-use hiking does not require a permit, but overnight float camping does — book through recreation.gov. Always verify current regulations with CPW before fishing.

Stop by Gunnison River Guides or local Gunnison-area fly shops for flies, current intel, and to support the shops that keep this fishery healthy.

Looking Ahead

Showers are likely through Monday with another round possible Tuesday — the sustained cloud cover should keep BWO hatches firing consistently through the week. With snowpack well below normal, flows are expected to stay manageable through May, which could extend the prime float season longer than a typical year.
