Crystal River at Redstone — Fishing Report for April 24, 2026
Quick Stats
Flow: 203 CFS | Trend: Stable | Fishability: Good | Weather: Mostly Sunny, High 64°F
The Bite
With a dry, low-snow year across the Colorado headwaters basin — snowpack sitting well below normal — the Crystal is running higher than you'd typically expect for late April, but not alarmingly so. At 203 CFS, flows are right at the edge of the ideal window and holding steady near the 10-day average, which suggests this isn't a spike — it's where the river wants to be right now. Wading will require attention, especially through faster pocket water, but the slower tailouts and inside bends are fully accessible and holding fish.
The sunny forecast today and tomorrow is the main wrinkle. BWOs need cloud cover to fire reliably, and with clear skies dominating the next 48 hours, don't count on a strong afternoon hatch. That said, midges will be active through the midday window — roughly 10 AM to 2 PM — and any passing cloud bank could trigger a brief Baetis flurry. Keep a dry box handy and watch the surface. The fish in this valley haven't seen much pressure since last fall, and they're not shy about eating with confidence when something comes off.
The better news arrives Sunday: showers and thunderstorms are in the forecast through the back half of the weekend, and that overcast, unsettled weather is exactly what the Crystal's BWO population needs to produce a real hatch. If you can fish Sunday or Monday, the dry fly window could be worth the wet jacket.
What to Fish
- Pat's Rubber Legs #10-12 — anchor fly, point position; gets the rig down fast in the fuller flows
- Pheasant Tail #18-20 — trailing 14–16" above the anchor; natural drift through mid-column
- RS2 (gray) #20 — swap in as a second dropper or replace the PT in slower, clearer tailouts
- Juju Baetis #20 — reach for this when cloud cover builds and fish start showing interest near the surface
- Griffith's Gnat #18-20 — midge dry option for midday surface activity in the slower flats
- Sparkle Dun BWO #18-20 — keep a few ready for any overcast window that develops
Tactics & Rigging
With flows on the fuller side, weight is your friend. Rig a Pat's Rubber Legs on point with a Pheasant Tail or RS2 trailing 14–16" above it on a 5X fluorocarbon tippet. Add enough split shot above the anchor to get the rig bouncing along the bottom quickly — you don't have time to sink in the faster runs. Focus on the inside seams of bends, the soft water behind mid-channel boulders, and the slower tailouts where fish can hold without burning energy. Let the rig ride the current naturally through these zones without mending too aggressively.
If cloud cover materializes in the afternoon, drop the nymph rig and tie on a Griffith's Gnat or Sparkle Dun on 6X fluorocarbon. The Crystal is intimate water — short casts, careful approaches, and drag-free presentations matter more than fly selection. Get low, move slowly upstream, and let the fly come to the fish rather than casting over them.
Access & Logistics
Highway 133 parallels the river throughout this stretch with consistent pulloffs — access is easy and the Avalanche Creek trailhead provides a good staging point for the upper section. At 203 CFS, the river is moving with purpose; scout your crossing points before committing. Crowds are essentially nonexistent here — one of the Crystal's best qualities in April.
Stop by Roaring Fork Anglers or Taylor Creek Fly Shop for flies, local intel, and to support the shops that keep these fisheries healthy.
Looking Ahead
Sunday's storm system is the event to watch — overcast skies and moisture through early next week should trigger the best BWO conditions of the spring on the Crystal. If flows stay manageable after the rain, next week could be exceptional dry fly fishing.
