RIGS Fly Shops & Guide Service's Tip of the Week

Recent afternoon rain showers have continued to influence the San Miguel, with daily flow increases following precipitation before the river settles back down through the evening. Water clarity has been fluctuating with these rain events, so expect conditions to vary from day to day depending on how much moisture the drainage receives. The most consistent fishing has continued to be during the cooler morning hours. We recommend beginning your day on the lower river, then gradually working upstream as the morning progresses. This pattern has allowed anglers to stay ahead of warming water temperatures while taking advantage of fish that remain active longer in the upper reaches. Caddis continue to dominate the hatch, providing excellent opportunities for dry-dropper fishing through much of the morning. A buoyant caddis adult or Chubby Chernobyl paired with a caddis pupa or emerger has been the most productive setup. As surface activity slows into the afternoon, transitioning to a nymph rig has produced the best results. Small stonefly nymphs, caddis larvae, and bright mayfly attractor patterns continue to account for the majority of fish. If you're planning to stay late, keep a dry fly ready. Evening caddis activity has continued to bring trout back to the surface during the final hours of daylight, creating some excellent dry fly opportunities before dark. While daily rain showers may temporarily change flows and clarity, anglers who adjust to the conditions are continuing to find quality fishing throughout the San Miguel.

Description: About San Miguel River

The breathtaking SanMiguelRiver begins high in the mountains above Telluride, Colorado. From Telluride, the troutfishing runs for over 45 miles to the northwest where it eventually becomes a warmwater fishery. The San Miguel is a high gradient, freestone river with average depths between 1 and 3 feet. It has abundant pocket water with occasional pools and riffle-like runs. It holds five species of trout with rainbows and cutbows being pre-dominant. The rocky streambed lends itself to a plethora of bug life with cadddis flies being the most prevalent. There is a major stonefly hatch of pteronarcys which occurs when the river is high and muddy. Possibly due to this, stoneflly nymphs are a major player throughout trout season. Like the Dolores, the whitewater nature of the river makes it difficult to cue on hatches. There are abundant hatches of caddis, which generally occur during extreme high water, when it is too early to fish. Fishing occurs all year, but primetime is late June through October. Dry-dropper rigs work well most of the year. Top dry flies are Stimulators and most varieties of caddis flies. Schroeder hoppers are a must have as the sesaon progresses and the water drops. Double nymphing can be extremely effective in deeper pools and runs (it is difficult to find water over 6 feet deep). Stellar nypmhs are 20 inchers and Orvis tunghead stoneflies. Smaller nymphs include beadhead flashback pheasant tails, Barr's emergers and red and black zebra midges. Most of the 45 mile stretch of trout water is public so find any pull-off that you have to walk a little and expend some energy to get to the river and have some luck.
