The Saint Vrain is yet another drainage where we're currently seeing higher-than-average flows for this time of year. Flows are changing daily, so calling the shop ahead of time is a good way to prepare for a day on either the North or South branches of the Saint Vrain. During colder streaks of weather, the fishing can be great as the clarity improves and fishing does accordingly. Dry droppers and nymph rigs can both be effective in the canyon, but don't look for dry fly eats to really pick back up again until flows drop back to around at least the 500 CFS range. In the canyon stretches, throwing a nymph rig with a larger attractor like a leech, stonefly such as a Pat's Rubber Legs or Girdle Bug, San Juan Worm, or caddis larva on point in the slower, deep boulder pools and walking-paced runs would be my rig of choice during runoff. On cloudier days, don't be shy of stripping a small streamer through these holding zones, as well. The North Saint Vrain at Wild Basin is also in play -- look for the water to be moving and up, but expect better clarity in this section. 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. On very warm days when the water is likely to be at its highest over the next few weeks, look for occasional sight fishing opportunities if fish are podded up in the flooded side waters.

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
