Colorado Fishing Report: Vail Valley and Beyond | October 26, 2026 Upper, Middle, and Lower Colorado River • Roaring Fork River • Eagle River
Fall fishing remains incredible across the Vail Valley and western Colorado. Recent rain has added a little water and shuffled clarity on several rivers, but our guides are finding excellent fishing with nymphs and streamers, along with some opportunities to cast dry flies to rising trout.
The Middle Colorado is our standout this week at a 9/10 rating, with productive nymphing and streamer fishing from Catamount to Dotsero. The Eagle is fishing great after a slight increase in flows, and the Roaring Fork is coming back into shape after muddy water from the Crystal River paused this fishery for a few days. Below Glenwood Springs, the Lower Colorado has cleared nicely and is offering good nymphing and exciting streamer action.
Summer crowds are gone, the scenery is beautiful, and there are plentiful, happy trout to keep your rod bent. We are not a seasonal fishery. Excellent fishing continues through fall and into winter, and some of our favorite days happen after most anglers have put their gear away for the season.
Brown trout are in their spawning season. Enjoy the fishing, but give spawning fish and their gravel beds plenty of space. You’ll find more on responsible fall fishing below.
Colorado River: Pumphouse to Catamount
Flow: 426 cfs at Pumphouse
Clarity: 3 feet
Fishing Quality: Unknown — no recent firsthand guide report
Our guides have been focusing on sections farther downstream over the past few weeks, so we do not have an up-to-date, firsthand fishing report for Pumphouse to Catamount.
Based on what is producing on the Middle Colorado, we would expect similar tactics to be a reasonable starting point here. That is an expectation, rather than a confirmed report from this stretch.
Start by looking for deeper runs, soft current seams, and drop-offs. Stonefly and worm patterns would be sensible nymph choices, while smaller streamers such as a Thin Mint or white Crystal Bugger are worth carrying.
Watch for midges, blue-winged olives, and any consistent surface feeding before switching to dry flies. Let the conditions you encounter determine your approach.
Suggested Starting Flies:
Pat’s Rubber Legs, coffee/black size 8
San Juan Worm, worm brown size 14
Rainbow Warrior size 20
Thin Mint size 8
Crystal Bugger, white size 8
Parachute Adams size 20 if trout are rising

Colorado River: Catamount to Dotsero
Flow: 696 cfs at Dotsero
Clarity: 2.5 feet
Fishing Quality: ⭐⭐⭐⭐⭐⭐⭐⭐⭐☆ 9/10
The Middle Colorado is fishing excellent and has been a focal point for our guides this past week. Both nymphing and streamer fishing have been producing, making this one of our favorite options for a fall float right now.
The Thin Mint has been the clear standout streamer, followed by a white Crystal Bugger. Cover banks, current seams, and structure, and pay attention to which presentation produces a response. Repeat the productive angle and retrieve as you work through similar water.
Nymphing has also been excellent, especially with patterns that offer trout a substantial, opportunistic meal. Pat’s Rubber Legs, Mud Hustler Craws, and worm patterns have been particularly good along drop-offs and through deeper runs. Adjust your weight and depth as the river changes so your flies stay in the feeding zone.
A few blue-winged olives and midges are still around, although they are much less prevalent than they were in September. Cloudy days are creating some dry-fly opportunities. When you encounter a pod of rising fish, a size 20 Parachute Adams has been a good all-around choice.
Main Hatches & Feeding Opportunities
Below the surface: Stonefly, crawfish, and worm patterns are leading the nymphing program.
Cloudy-day opportunities: Watch softer seams and quiet water for trout rising to midges and blue-winged olives.
Between rising fish: Nymphing and streamers remain productive ways to cover water.

Parachute Adams — #20
CRO guide Brian Hilbert pro tip:
“Be patient with your nymphs, if you don’t hit a fish in a spot adjust your depth and weight before changing flies. This time of year trout are looking to take advantage of easy meals so if you’re not getting eats, it’s likely because your flies aren’t finding the fish.”
Colorado River: Below Glenwood Springs
Flow: 1,470 cfs at Glenwood Springs
Clarity: 2 feet
Fishing Quality: ⭐⭐⭐⭐⭐⭐⭐☆☆☆ 7/10
The Lower Colorado was affected by muddy water coming through the Roaring Fork from the Crystal River, but it has cleared nicely. Streamer fishing remains excellent on cloudy days and is still producing on clear, sunny days.
Black/silver Kreelex, olive/white Barely Legal, and black Sex Dungeon patterns have been strong choices. Yellow Sex Dungeons are also worth having in the box.
Mix up your retrieve, but our guides have been getting their best results with fast, sporadic movement. Quarter your cast upstream, place the fly close to the bank, and swim it downstream alongside the bank and structure. This presentation has been producing more reaction eats than a traditional down-and-across approach.
Manage your slack so you can stay connected to the fly as it moves toward you. A good cast only helps if you can make the streamer swim and feel the eat.
Nymphing is also good. Cranefly larvae, crawfish, and worms have been excellent point flies, while egg patterns and small midge pupae have been productive behind them.
One of our guides’ go-to combinations this month has been a cream size 6 Philly Cheese Cranefly, an orange size 18 Nuke Egg, and a red size 20 Day Saver Midge. Adjust the rig’s depth and weight to match each run.
Best Streamers
Kreelex — black/silver
Barely Legal — olive/white
Sex Dungeon — black or yellow
Best Nymphs
CRO guide Matt Fletcher pro tip:
“Quarter your streamer cast upstream and get the fly swimming along the bank. Stay connected with your line, then use quick, irregular strips to create that swimming motion. Pay attention to the retrieve that produces, and repeat it on the next good bank.”
Roaring Fork River
Flow: 679 cfs at Glenwood Springs
Clarity: 1.5–2 feet
Fishing Quality: ⭐⭐⭐⭐⭐⭐⭐⭐◐☆ 8.5/10
The Roaring Fork blew out last Thursday, October 22, when muddy water entered from the Crystal River. It is just coming back into shape today, October 26.
Before the blowout, fishing was exceptionally good. As clarity continues to improve, we expect the Fork to return to that productive pattern. The 8.5/10 outlook reflects the strong fishing before the blowout and improving conditions, rather than a claim that every stretch has fully recovered.
Stoneflies, worms, and small baetis patterns were doing much of the work. A size 8 Pat’s Rubber Legs or Twenty Incher Stone provide a larger offering, while a size 14 San Juan Worm and size 22 Hilbert’s Day Saver May BWO round out a productive selection.
Start in softer current lanes, deeper runs, and seams where trout can feed without fighting the strongest flow. As the day proceeds, target faster riffles and drop offs where trout will concentrate to feed.
A little remaining color can make a larger stonefly or worm a useful lead fly. Keep the small baetis pattern in the mix as visibility improves.

Additional Stonefly Option
Twenty Incher — #8
CRO guide Matt Weldon pro tip:
“As the Fork clears, start with a stonefly or worm and a small baetis behind it. Work the softer seams thoroughly and adjust your depth as you move between runs. Check your flies for debris constantly so each drift starts clean.”
Eagle River
Flow: 143 cfs at Gypsum
Clarity: 2.5 feet
Fishing Quality: ⭐⭐⭐⭐⭐⭐⭐⭐☆☆ 8/10
The Eagle is fishing great. Recent rain has increased flows slightly, and opportunistic food sources have been producing especially well. Worms, cranefly larvae, and leeches are strong choices for a lead fly. Fish them through soft water, along drop-offs, and into deeper pools where trout can hold comfortably and intercept food.
Midges and blue-winged olives are still hanging around, and Hilbert’s Chocolate Sexi Top May in size 20 has been excellent. Keep it ready when fish are feeding on smaller insects.
Egg patterns are also working well, with orange shades are producing best. An orange size 18 Nuke Egg is a good choice, but presentation and location matter: fish feeding water away from redds, and leave actively spawning trout alone.
Spend time working the slower seams and changes in depth. A careful drift through a productive pool is often more valuable than rushing to the next spot.
Best Nymphs & Emergers
CRO guide Sam Kinney pro tip:
“Concentrate on the soft water and the drop into each deeper pool. Start with a cranefly, worm, or leech, then pair it with an orange egg or small insect pattern. Adjust your weight before changing the whole rig, a good drift at the right depth can make the difference.”
Fish Welfare: Respect the Brown Trout Spawn
Fall brings beautiful brown trout and an important responsibility for everyone spending time on the river.
Brown trout spawn in the fall, creating gravel nests called redds. These often appear as lighter, freshly cleaned patches among darker gravel in shallow water. Give these areas a wide berth, whether or not fish are visible.
Leave actively spawning trout alone. Avoid casting to fish paired over clean gravel, digging nests, or repeatedly holding on a spawning bed. There is plenty of productive fishing elsewhere.
Watch your footing. Never walk across redds or drag an anchor through spawning gravel. Eggs remain in the gravel after adults leave, so an empty-looking bed still deserves protection.
Choose your water thoughtfully. Focus on deeper pools, established runs, and feeding lanes away from spawning areas. Using an egg pattern does not change that responsibility.
Handle every trout carefully. Use a rubber-mesh net, wet your hands, keep fish in the water while preparing for a photo, and minimize air exposure. Support fish gently, avoid squeezing their bellies, and release them promptly.
At CRO, a great day includes taking care of the fishery that makes it possible. Enjoy the fall bite, give spawning fish their space, and help protect the next generation of trout.
