Pull out your magnifiers, knock the dust off your light tippet, and reach for your smallest hooks and finest thread—the “fisherman’s curse” has arrived. Tricos are here on the Eagle River, and for those of us fishing the Vail Valley, this is one of the most anticipated hatches of the season. All the jokes aside, the Trico hatch is a favorite for both anglers and trout alike. When it’s on, it puts fish in the net and creates some of the most technical—and rewarding—dry fly fishing you’ll find all year.
The past few days have been incredibly consistent, and the hatch is following a predictable rhythm with three distinct stages each morning. Early on, before the Tricos really get going, a very small dark baetis pattern can get things started. As the morning progresses and you begin to see the Trico migration over the water, it’s time to switch to an emerger. Then, once the adults fall spent and disappear from the surface, fishing a drowned spinner or low-riding adult becomes the most effective approach. It’s a game of observation and timing, and having one of our guides alongside to help read the water, identify the stage, and dial in fly selection can make all the difference. Fishing the Trico hatch is a lot like a long baseball season—if you’re batting .300, you’re doing just fine.
Fortunately, there’s more than just tiny bugs on the menu right now. From Avon down through Gypsum, the river is loaded with opportunity. Golden stoneflies have started moving, and their shucks are becoming more noticeable along exposed rocks and structure, signaling increased activity. The tail end of the PMDs and Yellow Sallys are still hanging around as well, giving trout a variety of food sources to key in on throughout the day.
And if you’re not a fan of tiny flies, the evening bite continues to deliver. Caddis activity in the afternoons and evenings around Vail and Avon remains strong, offering a chance to fish larger dries and enjoy more aggressive takes. It’s a perfect balance—technical mornings with Tricos, followed by more forgiving, high-action fishing later in the day.
This season has truly been something special. Between strong water levels, ideal temperatures, and consistent bug activity, it’s the kind of year guides and anglers hope for. Sitting here in Eagle, Colorado, listening to rain on the porch, it’s a relief to be talking about great fishing conditions rather than stressing over fish health during the heat of the day. It’s a reminder of how good things can be when everything lines up.
If you’re not fishing the Vail Valley this week, now is the time to change that. Whether you’re dialing in Tricos with one of our experienced guides or enjoying a relaxed evening caddis hatch, the Eagle River is fishing as well as it gets in late summer. Bring your small bugs, be ready for a challenge, laugh when a big brown trout puts you to the test on light tippet, and enjoy the river at its absolute finest.
