SAN MIGUEL RIVER

Last Update: September 11, 2025


The San Miguel River with its near endless public access (25+ miles) from its headwaters near Telluride, heading northwest to its confluence with the Dolores, beckons walk wade anglers to explore one of Colorado's last freestone (undammed) trout streams. Only 30 minutes from Ridgway, the San Miguel is a dry fly fishing paradise. With numerous insect hatches, you will find stoneflies, caddis, pale morning dun, blue winged olives and midges on your angling adventure. San Miguel anglers encounter steady river gradient, coupled with great stream clarity, abundant pocket water and some nice deep buckets and pools.

Happening Now
The San Miguel continues to fish exceptionally well through both the morning and afternoon hours. Recent afternoon rains have helped stabilize flows, and water temperatures remain in an ideal range. Deep dry-dropper rigs are leading the way, consistently delivering flies into the strike zone. Swinging small streamers and soft hackles has also been highly productive at current flows. On slower days, patience and persistence are paying off. Caddis activity is strong, and anglers are beginning to see scattered PMDs in the afternoons. While fish are showing less interest in large foam hoppers, downsizing to smaller patterns has been the key to steady surface action. This trend of quality dry-fly fishing should hold well into the fall season. Looking ahead, cooler weather and additional rainfall are in the forecast, which should further improve water conditions. October Caddis will soon begin to emerge, marking the seasonal transition and adding to the already robust hatch activity. With flows gradually receding and insect life on the rise, the San Miguel is primed for some of the best fishing of the year in the weeks to come.

TIPS FOR

THE SAN MIGUEL RIVER

While Summer and Fall are the best seasons to target fly fishing the San Miguel River, don’t discount early Spring for getting a line wet. Winter fly fishing near Telluride is best discovered at lower elevation rivers like the Uncompahgre or Lower Gunnison. “Keep moving” is the motto on the San Miguel River. With over 25 miles to pick from and quick access to multiple stops, don’t walk up on other groups or try to compete for water. Instead, explore alternate locations not to overfish any one section.

Weather on the San Miguel should not be discounted. Don’t forget you are in Colorado above 7000 feet, and weather changes quickly in high-elevation canyons like the San Miguel. So be prepared for potential flash floods and sudden shifts in temperature and weather. Consider moving upstream to locate clear water above tributaries brining in off-colored water.

Fly Fishing Gear & Equipment for the San Miguel River:

  • 3 weight to 5 weight, 7’6” to 11’ moderate action Fly Rods with WF floating fly lines are ideal for high sticking pockets or presenting drag free drifts in fast riffle water or controlled drifts near tight vegetated banks.
  • 6x to 5x leader & tippets will cover most situations. Consider shorter length leaders to turn over small attractor dry flies with a dropper in tight quarters, or slightly longer leaders to present small dry flies with improved accuracy and drag free drifts.
  • Core dry flies for match the hatch, small attractor flies, small jigged nymphs and plenty of terrestrials are essential in the San Miguel. Visit the Fly Shop for a curated selection of proven and successful fly patterns ideal for the specific drainage and time of year you are visiting.
  • Small poly yarn indicators for the occasional deep pool, and dry fly flotant or dry shake for combating turbid waters. *Don’t forget your net for proper catch and release fish handling.
  • Backcountry essentials like a quality rain jacket, day pack, bug spray, and plenty of packable food and water for a full day of exploration.
