Fly Fishing Rio Chama

Fly fishing Rio Chama – Below Abiquiu Dam provides an accessible and productive tailwater experience along five to seven miles of designated Special Trout Water from Abiquiu Dam downstream to the US-84 bridge. This lower section of the Rio Chama flows through a picturesque high-desert landscape where red and cream-colored sandstone bluffs rise above cottonwood-lined banks, and the iconic Cerro Pedernal and Abiquiu formations that inspired Georgia O'Keeffe's paintings frame the valley. Dam-controlled releases from Abiquiu Reservoir maintain flows between 80 and 400 CFS, delivering cold, clear water that supports a quality trout fishery in an otherwise arid environment. The wade-only access and Special Trout Water designation with reduced bag limits help maintain a healthy population of catchable trout throughout this reach. Rainbow trout are the most abundant species in this section, benefiting from regular stocking supplemented by natural reproduction in the gravel-bottomed runs below the dam. Brown trout are present in lower numbers but tend to run larger, occupying the deeper pools, logjams, and shaded undercut banks along the corridor. Rainbows typically range from 10 to 15 inches, with fish to 18 inches available in the best holding water near the dam. Browns average 12 to 16 inches, with occasional fish exceeding 20 inches for anglers willing to target them with streamers and large nymphs during low-light conditions. The Special Trout Water regulations encourage catch-and-release practices that help these fish reach impressive sizes. The hatch calendar below Abiquiu Dam shares many characteristics with the upstream El Vado tailwater but operates on a slightly earlier schedule due to the lower elevation and warmer ambient temperatures. Midges are the most reliable year-round food source, with Zebra Midges, Mercury Midges, and Griffith's Gnats in sizes 20 to 24 essential for winter and early spring fishing. Blue-Winged Olives appear as early as late February in warm years and continue through May, with a strong fall resurgence from September through November. Caddis hatches build through May and peak in June and July, with tan and olive Elk Hair Caddis in sizes 14 to 18 producing explosive surface takes in the evening. Pale morning duns provide quality dry fly fishing from late May through July, and terrestrial patterns including hoppers, beetles, and ants are effective from July through September along the grassy banks and cottonwood-shaded runs. Nymph fishing is the bread-and-butter approach on this section and produces fish consistently throughout the year. A standard indicator rig with a two-fly nymph setup covering sizes 16 to 20 is the most popular method. Pheasant Tails, Hare's Ears, Flashback RS2s, and small Prince Nymphs are proven producers in the riffles and runs. San Juan Worms in red and brown are effective after rain events or flow increases when the river picks up color. Euro-nymphing techniques work exceptionally well in the faster pocket water and transitional runs where trout stack up below current breaks. Streamer fishing with Woolly Buggers, Zonkers, and small Clousers in sizes 6 to 10 swung through the deeper pools targets the resident browns and can produce the largest fish in this section, especially during overcast or rainy conditions. Seasonal patterns on this stretch reward anglers who time their visits carefully. Winter fishing from December through March is productive during midday midge hatches when water temperatures reach their daily peak, and the tailwater stays ice-free even during cold snaps. Spring from April through May brings the best BWO hatches and increasingly active fish as water temperatures climb. Summer fishing is excellent but anglers should target early morning and late evening sessions to avoid the intense high-desert sun, and flows can fluctuate significantly during irrigation season. Fall from September through November offers arguably the best overall fishing, with reliable hatches, comfortable weather, and brown trout becoming increasingly aggressive as they prepare to spawn. Access to the Below Abiquiu Dam section is straightforward. The upper end is reached via the road to Abiquiu Dam off US-84, with parking available near the base of the dam. US-84 parallels the river for much of this stretch, providing multiple pulloff access points along the corridor. The drive from Albuquerque takes approximately one hour and forty-five minutes northwest via US-84, making this one of the most accessible quality trout fisheries for Albuquerque-based anglers. A New Mexico fishing license is required, and Special Trout Water regulations apply with reduced bag limits and specific gear restrictions that anglers should review before fishing. The combination of reliable tailwater fishing, scenic high-desert beauty, and convenient access from Albuquerque makes the Below Abiquiu Dam section of the Rio Chama an outstanding year-round fly fishing destination.
