River Statistics:
The St. Vrain has been fishing well on both the north and south branches, as well as down farther through town in Lyons. Flows can be touch-and-go this time of year, with water often coming down heavy in May and June, especially in the south branch. A dry dropper rig is almost always appropriate on the St. Vrain, with go-to classics like the stimulator, humpy, para adams, and elk hair caddis always doing damage. If the water is high and off-color, try a bigger attractor like a chubby chernobyl up top. Short-ish nymph rigs can always work well in here too, especially during spring flows when the water is high and cold. Leeches, flashy stonefly patterns like the tungstone, pat's rubber legs, micro stone, etc., can all do well sub-surface. During cold streaks when we get better water clarity, size down and try flies like the frenchie, micro may, pheasant tail, rainbow warrior, psycho prince, etc., in #14-18 sizes. The north branch of the St. Vrain can often fish more like a tailwater, with fish at times preferring smaller flies like baetis and midge patterns, even in the spring. Sometimes leading with a flashy nymph or worm and then trailing down to a more realistic bug can be a great move when nymphing on the St. Vrain in the springtime. Whatever your approach ends up being, enjoy hitting some of our most local waters and get out there on the St. Vrain!

The Ultimate Fly Fishing Report
Casting a fly in a tranquil mountain stream, feeling the tug on the line, and holding a beautiful rainbow trout makes us feel alive and intensely connected with nature. Fly fishing is our way of life and we are blessed with hundreds of nearby rivers and streams just a short distance away from Boulder. From the swift spring waters of the Clear Creek to the meandering bends of the South Platte, it's critical to consider fishing conditions in advance and prepare accordingly. We rely on our experienced guides who venture into the wild to let us know which rivers favor fly fishing, where fish are biting, and which fly patterns are most effective. Planning a successful fishing trip also requires knowledge of stream flows at various river points and an accurate weather forecast for a given destination.
