Month-by-month hatch timing, fly pattern recommendations, and current conditions for the Red River in northern New Mexico in 2026. A high-elevation Sangre de Cristo freestone stream with wild trout and consistent caddis and PMD hatches from May through October.
Red River Hatch Calendar — Quick Reference
The Red River flows south from its headwaters near the ski town of Red River through a steep canyon before joining the Rio Grande near the Taos Gorge. The upper sections around the town of Red River and downstream through the canyon hold wild rainbow, brown, and cutthroat trout. Much of the river corridor is within Carson National Forest with good public access.
The Red River is a small freestone mountain stream. It runs fast and clear through canyon sections, with pockets and plunge pools holding the most fish. Spring runoff can blow out the river into May in heavy snow years. By late May or June flows drop to fishable levels and the caddis hatches begin. The upper sections near town tend to be stocked; the canyon water below holds more wild fish.
Caddis are the primary surface event from May through August. PMDs emerge in June and July on the better sections. Trico spinners appear on the smoother runs in July and August. Fall brings BWO hatches and Autumn Caddis activity through September and October, extending the season into the aspens.
The canyon below the town is accessible on foot from various pullouts along NM-38. Some sections require short hikes to reach the better water away from the road. The river receives less traffic than the San Juan or Rio Grande Gorge and offers a quieter mountain trout fishing experience in a scenic northern New Mexico setting.

Hydropsyche sp.
Caddis are the most reliable hatch on the Red River from May through August. Evening emergences in the canyon sections bring fish up in the pockets and pool tails. An Elk Hair Caddis in size 14 to 16 covers most situations. Attractor patterns like a yellow Stimulator also work well in the faster pocket water where precise pattern matching is less critical.
Recommended: Elk Hair Caddis, Stimulator #14-16
Ephemerella infrequens
PMDs emerge on the Red River in June and July, overlapping with the caddis for the most productive surface fishing of the year. Afternoon emergences draw fish up in the smoother runs and pool tails. A Sparkle Dun in size 16 to 18 is the standard. The canyon sections below town see the most consistent PMD activity away from the stocked water.
Recommended: PMD Sparkle Dun, Comparadun #16-18
Baetis sp.
BWOs bookend the Red River season in April and October. Spring Baetis hatches in April arrive as snow is still possible at elevation, often on overcast afternoons. Fall BWO fishing in October coincides with peak aspen color in the Sangre de Cristo Mountains, making it one of the more scenic dry fly opportunities in northern New Mexico.
Recommended: Sparkle Dun, CDC Dun #18-22
Neophylax sp.
The Autumn Caddis hatch on the Red River in September and October closes out the season on a strong note. Large orange-bodied caddis emerge in the afternoons and fish respond well after a summer of smaller patterns. The cooler fall temperatures also improve trout activity in the canyon. An Orange Stimulator in size 12 to 14 is the right fly.
Recommended: Orange Stimulator, October Caddis #12-14
Common Questions
The Red River is a tributary of the Rio Grande in Taos County in northern New Mexico. It flows south from the town of Red River through a canyon in Carson National Forest before entering the Rio Grande Gorge. NM-38 follows the river through much of the canyon, providing good access to public water throughout the fishable stretch.
Yes. While sections near the town of Red River are stocked, the canyon sections downstream hold wild rainbow, brown, and cutthroat trout that reproduce naturally. Wild fish in the canyon tend to be in better condition than stocked fish near the town. The further downstream into the canyon you fish, the more likely you are to encounter wild trout.
Late May through June and September through October are the best windows on the Red River. Late spring brings the main caddis and PMD hatches once runoff subsides. Fall brings BWOs and Autumn Caddis alongside the turning aspens in the Sangre de Cristo Mountains. Midsummer can see lower flows, so early morning fishing is recommended to avoid warm afternoon water in exposed sections.
