The N and S St. Vrain forks continue to fish very well on dries and dry droppers. We've also been hearing good things about the Vrain right through town in Lyons. The town stuff is definitely a different experience from being up in either canyon, but some of the bigger fish in the system can hold in those pools. Recent trips to the South St. Vrain have seen an impressive number of yellow sallies hanging around, along with some drakes and of course caddis. A small #14 parachute hopper can bring a ton of fish to the surface in here, especially on cloudier days or during the lower light hours of roughly 4-7 PM, as can other dries such as #16-18 black beetles and ants and small elk hair caddis or parachute adams in the same size range. As always, in waters like the St. Vrain that are easily accessible from roads like 7 and 36, try hoofing it a bit away from the water closest to your chosen pull-off. It can be amazing what a difference just a quarter mile of walking, or a short scramble down a rocky slope, can make in terms of finding less-pressured water. The North Saint Vrain at Wild Basin has also reportedly been some great brookie fishing lately. A dry dropper setup with a #12-14 Elk Hair Caddis, Stimulator or beetle on top dropping to a #14-16 soft hackle pheasant tail, caddis pupa, or micro may is generally a good bet in the pocket water up here. The higher up you get on his arm of the Vrain in RMNP, the more chance you have at picking up some Cutthroat trout in the mix with the Brookies and occasional browns.

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.
