The Red River is a cold-water tailwater that holds trout year-round

The Red River flows north from the Sangre de Cristo Mountains and enters the Rio Grande just below Taos. It is a tailwater — cold water released from a dam upstream — which means it stays fishable through the heat of summer and holds trout when other New Mexico streams warm up. The river runs through a narrow canyon with steep banks, and the best access is along the main road that parallels the water for about 15 miles from the dam down to the confluence.

The Red River is known for consistent brown trout and rainbow trout populations. The upper sections near the dam are narrower and faster, with pocket water and small pools. The middle and lower sections widen slightly and hold deeper runs. Water temperature stays in the 50s and 60s Fahrenheit most of the year, which is cold enough to keep trout active even in July and August.

Key Takeaways

  • The Red River is a tailwater below a dam, so water temperature and flow are controlled and the river stays cold year-round.
  • Access is easiest along the main road that runs the length of the river, with several pullouts and parking areas between the dam and Taos.
  • Small nymphs and dry flies work best; the river is narrow and technical, so light tippet and accurate casting matter more than distance.
  • New Mexico fishing licenses are required, and the Red River has a daily bag limit of two trout per day with a 12-inch minimum length.

Where to Access the Red River

The main access point is at the dam itself, where a parking area sits at the top of the canyon. From there, the river road (Forest Road 487) runs downstream and provides pullouts roughly every mile or so. Most of these are small — room for two or three vehicles — so arrive early on weekends. The road is paved for the first few miles, then becomes gravel but remains passable in a standard vehicle year-round.

The lower sections near Taos are accessible from the town itself. The Red River flows through a public area just north of Taos, and several informal pullouts line the road as it approaches the confluence with the Rio Grande. This section is easier to reach and often less crowded than the upper canyon, though the water is slightly warmer and the trout are more selective.

What Flies and Tackle Work Best

The Red River is a nymph river. Small dark nymphs in sizes 16 to 20 — pheasant tails, hare's ears, and small stonefly patterns — catch most of the trout. Fish them under a strike indicator in the deeper runs and pocket water. The water is clear and the trout are wary, so use 5X or 6X tippet and keep your line off the water as much as possible.

Dry fly fishing works in early morning and late evening, especially in spring and fall. Small caddis patterns (sizes 16 to 18) and mayfly imitations bring rises in the slower sections. The river is narrow enough that you can often sight-fish to individual trout, which means a 9-foot rod and accurate casting are more valuable than a longer rod. A 3-weight or 4-weight fly rod is ideal; anything heavier will feel clumsy in the tight canyon.

Seasons and Water Conditions

Spring runoff (April through June) raises the water level and makes the river harder to fish, though it is still possible with larger nymphs and heavier indicators. Summer (July through September) is the most reliable season — water is cold and stable, and the river is fishable every day. Fall (October through November) brings lower water and selective trout, but also some of the best dry fly fishing of the year.

Winter (December through March) is cold but the river does not freeze solid. Water flow is lower and more predictable than in spring. Trout are less active but still feed, and you can catch fish on small nymphs if you fish slowly and deliberately. Check current conditions with the Bureau of Land Management office in Taos or with local fly shops before you go, because dam releases can change water level quickly.

Regulations and Licensing

You need a New Mexico fishing license to fish the Red River. Licenses are available online through the New Mexico Department of Game and Fish website, at sporting goods stores in Taos, or at the BLM office. A one-day license costs less than a full-year license if you are just passing through.

The Red River has a daily bag limit of two trout per day with a 12-inch minimum length. Catch-and-release fishing is common and encouraged, especially in the upper canyon where trout are smaller and more numerous. No special permits are required; the standard state license covers all public water on the Red River.

Nearby Services and Lodging

The town of Red River sits about 40 minutes north of Taos and offers lodging, restaurants, and fly shops. The Red River Chamber of Commerce website lists hotels and vacation rentals. Several fly shops in Taos and Red River sell local flies, rent equipment, and offer guided trips if you want a local to show you the water.

Camping is available at several Forest Service campgrounds along the river road, including Elephant Rock and Fawn Lakes. These fill quickly on weekends in summer, so arrive early or book ahead. The nearest larger town with full services is Taos, about 30 minutes south.

Common Mistakes and How to Avoid Them

The most common mistake is fishing too fast. The Red River is small and the trout are spooky. Slow down, watch the water, and cast to specific fish rather than covering water. Many anglers also use tippet that is too heavy; 5X or 6X is standard here, and 7X works in low water and bright sun.

Another mistake is arriving without a plan for where to fish. The canyon is long and the pullouts are small. Pick a section — upper canyon for technical nymph fishing, middle section for a mix of nymphs and dries, lower section for easier access — and fish that section thoroughly rather than driving the whole road looking for the "best" spot.

Frequently Asked Questions

Can I fish the Red River in winter?

Yes. The river does not freeze solid and trout feed year-round. Winter fishing is slower and requires patience, but it is a good option if you are in Taos during the cold months. Water is lower and clearer, which means smaller flies and lighter tippet.

Do I need a guide to fish the Red River?

No, but a guide is helpful if you have never fished a tailwater or if you want to learn the specific techniques that work here. Local fly shops in Taos and Red River offer half-day and full-day trips at standard rates. Walk-up fishing is also productive if you fish slowly and carefully.

What is the best time of year to fish the Red River?

Summer (July through September) is most reliable because water temperature is stable and the river is fishable every day. Fall (October through November) offers the best dry fly fishing. Spring runoff makes the river difficult but not impossible. Winter is slowest but still productive for patient anglers.

How far is the Red River from Taos?

The lower sections near the confluence are about 20 minutes north of Taos. The dam and upper canyon are about 45 minutes to an hour north. The main road runs the full length of the river, so you can fish different sections depending on how far you want to drive.

What size trout can I expect to catch?

Most trout on the Red River are 8 to 14 inches. Fish over 16 inches are less common but do occur, especially in the deeper runs of the middle and lower sections. The upper canyon near the dam holds more small trout and is better for learning the water and practicing technique.
