Both primary forks of the St. Vrain outside of Lyons are an awesome option right now, especially if you're looking to escape the high season crowds. The South St. Vrain along Highway 7 has been over performing in a big way, as it presents tons of fishable water and access, coupled with near-ideal water levels right now. Guides who've fished it recently have reported nice hatches of smaller caddis late in the day, along with plenty of yellow sallies and some drake mayflies. We've also seen a good number of larger stonefly nymphs in this system this season -- look for their casings to be pretty apparent on the rocks. If you're feeling inclined to nymph (sometimes a productive way to fish the Vrain when it's bright and sunny in the daytime), consider trying a smaller Girdle Bug/Rubberlegs-type stonefly nymph in a smaller size such as #10-12, or a yellow sally nymph like a Little Yellow Sloan or an Iron Sally. Yellow has been the hot color in here, with dry fly patterns such as a Stimulator and Elk Hair Caddis getting a lot of attention on top late in the day. 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 or caddis pupa 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. At Rocky Mountain Anglers, we are dedicated to providing all avid anglers with detailed and timely information about hatches, water, and weather conditions. So before you head out the door on your next fishing adventure, visit our web site to find valuable information that will prepare you for a successful trip. Have fun chasing after your next trophy trout and enjoy nature's beauty!The Rocky Mountain Anglers Crew
