Weekly AI Outlook as of 06/05/26
At 279 cfs and 64.9°F, the Rio Grande is running lean but fishable through both the Taos Box and Orilla Verde sections. No recent shop intel — outlook based on current conditions and seasonal patterns. Peak caddis activity should be strong in the 60+ degree water, with golden stones also active. The lower flows mean spookier fish and more technical presentations, but also concentrated trout in deeper pools and runs. Focus midday fishing when caddis are most active, and don't overlook nymph rigs in the morning before surface action picks up.
- Flow: 279 cfs — below typical June range but very fishable. Concentrate on deeper pools and channel edges where trout stage.
- Hatches: Peak caddis month with 64.9°F water temps. Golden stones also active. Elk Hair Caddis #14-16, Royal Stimulator key patterns.
- Water Temp: 64.9°F — ideal for both caddis emergence and golden stone activity. Trout metabolism ramped up for aggressive feeding.
- Best Window: Midday caddis emergence prime time. Morning nymph fishing before surface action, evening dry fly opportunities.

The Rio Grande through the Rio Grande Gorge in northern New Mexico runs through one of the most dramatic settings in the American Southwest — a deep volcanic canyon between Taos and the Colorado border. The fishery is challenging: hike-in access, technical wading, and a mix of wild brown trout, rainbows, and northern pike in some reaches. The Lower Box and Upper Box sections each demand a serious commitment but reward anglers with scenery and solitude unmatched in the region. Hatches center on caddis, BWO, and golden stones.
The Rio Grande Gorge through the Wild Rivers area is 800 feet deep — the deepest gorge in New Mexico — and the fly fishing access requires hiking down volcanic switchbacks that have turned away more anglers than they've welcomed.
January Outlook
January on the Rio Grande Gorge near Taos — winter conditions in the high desert canyon. The river flows through one of North America's most dramatic volcanic gorges at 7,000 feet elevation. Midge fishing in the lower Orilla Verde section is the winter option.
Productive Patterns
- Zebra Midge #22-24
- Pheasant Tail Nymph
- Scud (tan)
- WD-40
Tips
January in the Rio Grande Gorge is cold — temperatures can drop below zero at night. The Orilla Verde section (lower gorge) is accessible and wadeable at low winter flows. Midge fishing produces on mild days. The remote canyon scenery is extraordinary in winter conditions.
Water Notes
USGS 08313000. 400–800 cfs winter base. Water 38–46°F. Cold desert winter. High desert elevation — prepare for extreme cold.
February Outlook
February continues the Rio Grande's winter pattern. Low flows and cold water in the Taos Gorge. The Orilla Verde section is the most accessible. Mid-month warm spells can produce brief BWO activity.
Productive Patterns
- Midge Nymph
- Pheasant Tail
- Scud
- RS2 (mild days)
Tips
February on the Rio Grande is cold but fishable in the Orilla Verde. Watch for brief afternoon BWO activity on warm days. The canyon walls protect from wind — fishing in the gorge can be surprisingly comfortable.
Water Notes
400–700 cfs. Water 38–46°F. Winter low water. Good wading conditions but cold. Canyon walls provide wind protection.
March Outlook
March brings the Rio Grande's spring transition. BWO hatches begin in the Orilla Verde section. Snowmelt from the Sangre de Cristo and San Juan mountains begins to influence flows.
Productive Patterns
- Blue Winged Olive #18-20
- RS2
- Midge Nymph
- Hare's Ear
Tips
March on the Rio Grande is the beginning of the active season. BWO hatches begin on overcast afternoons. Flows can surge with early snowmelt — check USGS gauge before committing to the canyon. The Orilla Verde day-use area provides excellent access.
Water Notes
500–2,000 cfs. Water 42–50°F. Spring snowmelt beginning. BWO hatches on warm afternoons.
April Outlook
April marks the Rio Grande's spring runoff. High snowmelt flows from the mountains make the Taos Box unfloatable and wade fishing difficult. The lower Orilla Verde section fishes best at moderate flows.
Productive Patterns
- Streamer (high water)\
- Stonefly Nymph\
- Pheasant Tail\
- San Juan Worm
Tips
April runoff on the Rio Grande can be formidable — the Taos Box fills with dirty snowmelt water. The Orilla Verde section at the lower end of the gorge receives cleaner flow. Wait for late April when flows begin to moderate for the best conditions.
Water Notes
1,000–5,000 cfs. Water 42–52°F. Peak snowmelt runoff. Taos Box may be too high for float. Check USGS daily.
May Outlook
May is the prime Rio Grande season as runoff moderates. Caddis hatches begin in the gorge sections. The Taos Box float becomes accessible as flows drop. Wild brown and rainbow trout are aggressive after high water.
Productive Patterns
- Elk Hair Caddis
- Blue Winged Olive
- Stimulator (stonefly)
- Soft Hackle
Tips
May on the Rio Grande is excellent as the transition from runoff to prime conditions occurs. Monitor flows daily — the target range for the Taos Box float is 600-1,500 cfs. Below 600 cfs the upper gorge gets technical for rafts. The Orilla Verde section fishes well throughout May.
Water Notes
500–2,500 cfs. Water 48–58°F. Runoff moderating. Excellent conditions in the second half of May. Taos Box float opening as flows drop.
June Outlook
June is the Rio Grande's prime month. Flows are at ideal levels for both the Taos Box float and the Orilla Verde wade sections. Caddis hatches dominate and the wild brown and rainbow trout are aggressive.
Productive Patterns
- Elk Hair Caddis #14-16
- Royal Stimulator
- Parachute Adams
- Soft Hackle Wet
Tips
June on the Rio Grande is outstanding. The Taos Box float at 400-800 cfs is world-class — dramatic basalt canyon walls, excellent wild trout, and one of the most scenic float trips in North America. Book a guide for the Taos Box first time. The Orilla Verde provides excellent wade access.
Water Notes
400–1,500 cfs. Water 52–60°F. Outstanding summer conditions. Prime month for the Taos Box float trip.
July Outlook
July continues excellent Rio Grande fishing. Summer monsoon season begins in late July — afternoon thunderstorms can spike flows temporarily. Morning fishing is most reliable before afternoon storm development.
Productive Patterns
- Elk Hair Caddis
- Hopper #8-12
- Ant #16-18
- PMD #16-18
Tips
July on the Rio Grande is excellent — terrestrial season begins and the high desert canyons produce good hoppers and ant activity along the cliff edges. Fish the morning hours before afternoon monsoon development. The Orilla Verde is excellent for wade fishing.
Water Notes
300–1,500 cfs. Water 54–62°F. Summer monsoon season beginning. Morning fishing best. Afternoon thunderstorms possible.
August Outlook
August monsoon season on the Rio Grande. Afternoon thunderstorms can muddy flows temporarily. Morning fishing is essential. The Orilla Verde section recovers quickly after storms due to the canyon substrate.
Productive Patterns
- Hopper
- Ant #18
- Elk Hair Caddis (morning)
- Bead Head Stonefly
Tips
August mornings on the Rio Grande before the monsoon development are excellent — hoppers along the canyon edge and caddis in the riffles. The fish are in their summer lies. Avoid the canyon during lightning storms.
Water Notes
300–2,000 cfs. Highly variable due to monsoon. Water 56–64°F. Morning fishing essential. Afternoon storms produce temporary spikes.
September Outlook
Fall transition on the Rio Grande. The monsoon season ends and stable fall conditions return. Excellent caddis and BWO fishing in the Orilla Verde and lower Taos Box sections. Pre-spawn brown trout become aggressive.
Productive Patterns
- Blue Winged Olive #18-20
- Elk Hair Caddis
- Streamer
- PMD #16
Tips
September on the Rio Grande is outstanding — stable conditions return after the monsoon and the fish are aggressive. Pre-spawn brown trout in the deeper canyon pools respond to streamers. BWO hatches on overcast afternoons are excellent.
Water Notes
300–1,000 cfs. Water 52–60°F. Outstanding fall conditions. Stable flows returning after monsoon season.
October Outlook
October is one of the Rio Grande's finest months. Pre-spawn brown trout are aggressive and the cottonwood trees along the river corridor are brilliant gold. BWO hatches on cool afternoons produce consistent surface action.
Productive Patterns
- Blue Winged Olive
- Streamer (olive/sculpin)
- Elk Hair Caddis
- Pheasant Tail
Tips
October on the Rio Grande is exceptional — the combination of aggressive pre-spawn brown trout, reliable BWO hatches, and spectacular fall colors along the canyon makes this one of the finest October fisheries in the Southwest. The Orilla Verde is beautiful in fall.
Water Notes
300–800 cfs. Water 48–56°F. Outstanding fall conditions. Cottonwood gold in the canyon. Trophy brown trout season.
November Outlook
November on the Rio Grande brings late fall conditions to the gorge. Post-spawn brown trout feed aggressively. Midge fishing returns as the season transitions toward winter. The BLM Orilla Verde area provides excellent late season access.
Productive Patterns
- Blue Winged Olive
- Midge Nymph
- Pheasant Tail
- Scud
Tips
November on the Rio Grande is excellent and solitary — few anglers visit the gorge in late fall. Post-spawn fish are aggressive and the canyon scenery is stark and beautiful. Midge and small nymph fishing produces consistently.
Water Notes
400–800 cfs. Cooling 42–50°F. Late fall canyon conditions. Excellent late season opportunity.
December Outlook
December returns the Rio Grande Gorge to winter conditions. The cold desert canyon is dramatic in winter — snow on the canyon rim, clear cold water below. Midge fishing for wild brown and rainbow trout in one of North America's most spectacular settings.
Productive Patterns
- Zebra Midge #22-24
- RS2
- Pheasant Tail
- Scud
Tips
December on the Rio Grande is for the dedicated — cold canyon temperatures, short days, but stunning scenery and surprisingly active fish in the cold tailwater sections. The Orilla Verde is the best winter access point.
Water Notes
400–700 cfs. Water 36–44°F. Winter canyon conditions. Cold but fishable for dedicated winter anglers.
