Fly Fishing Red River

Fly fishing Red River – Below Fish Hatchery sends anglers into a dramatic canyon stretch where the Red River descends four to five miles from the state fish hatchery downstream to its confluence with the Rio Grande. This lower section of the Red River cuts through a steep, rocky gorge that grows progressively deeper and more remote as it approaches the Rio Grande, offering a markedly different character from the open meadow water upstream near Questa. Flows typically range from 20 to 100 CFS, creating a compact freestone stream that tumbles over boulders, cascades through chutes, and pauses in surprisingly deep plunge pools carved into the volcanic basalt walls of the canyon. The wade-only access and rugged terrain limit angling pressure, making this one of the more secluded trout fishing opportunities in the Taos area. Brown trout are the dominant species in this canyon stretch, thriving in the deeper pools, undercut ledges, and shaded lies that the gorge provides. Rainbows are well represented throughout the run, particularly in the riffles and faster pocket water, and cutbow hybrids add genetic diversity to the fishery. Fish sizes average 9 to 13 inches, but the lower canyon near the Rio Grande confluence holds some larger browns that benefit from the nutrient input and forage base of the bigger river system. Occasional fish in the 16- to 18-inch range reward anglers who probe the deepest pools and most technical lies with careful presentations. Hatch activity on this canyon stretch follows the general northern New Mexico pattern but benefits from the sheltered microclimate the gorge creates. Blue-Winged Olives hatch reliably from March through May and again from September through November, with sizes 18 to 22 producing the best results during overcast or drizzly conditions. Caddis emerge in good numbers from May through August, and an Elk Hair Caddis or Peacock Caddis in size 16 fished through the riffles is a consistent producer. Small golden stoneflies appear in June along the faster cascades, and midges provide year-round subsurface opportunities in sizes 20 to 24. The canyon walls create shade that moderates water temperatures during summer, often extending hatch windows later into the morning and earlier into the evening compared to more exposed water upstream. Nymph fishing is the most consistently productive approach on this stretch, given the depth and turbulence of many of the pools. Bead-head Pheasant Tails, Copper Johns, and Lightning Bugs in sizes 16 to 20 fished tight to the bottom through the plunge pools account for the majority of fish caught here. A two-nymph rig with a heavier point fly and a smaller dropper covers the water column efficiently. Tight-line and Euro-nymphing methods are particularly well suited to the canyon's pocket water, allowing anglers to maintain bottom contact through the short, fast drifts that characterize much of this reach. Small streamers such as Woolly Buggers, Slump Busters, and Conehead Sculpins in sizes 8 to 12 are effective for targeting the larger browns, especially during lower-light conditions early and late in the day. Seasonally, the Below Fish Hatchery stretch fishes best from late June through October once spring runoff subsides and the river drops to wadeable levels. Summer provides excellent dry-dropper fishing through the canyon, with morning caddis activity and afternoon terrestrial opportunities when hoppers and beetles blow into the gorge from the rim above. Fall is prime time for brown trout as spawning fish move into this section, and streamer fishing during October and November can produce the largest fish of the year. Winter fishing is possible but challenging due to limited daylight in the deep canyon and cold temperatures, though midday midge hatches still bring fish to the surface in the slower pools. Access requires some planning and physical effort. The upper end of this stretch is reached via the Red River State Fish Hatchery near Questa off NM-515, where a trail follows the river downstream into the canyon. The hike becomes progressively steeper and more rugged as the canyon deepens toward the Rio Grande confluence. Anglers should wear sturdy wading boots with good ankle support and carry sufficient water, as there is no shade relief on the rim trail during summer months. The drive from Albuquerque takes approximately three hours via I-25 north to NM-68 and NM-38. A New Mexico fishing license is required, and anglers should check current NMDGF regulations for any special rules on this section. The combination of canyon solitude, quality brown trout water, and technical wade fishing makes the Below Fish Hatchery stretch a rewarding destination for experienced anglers seeking adventure.
