The St. Vrain is in full Spring fishing mode, more water, more bugs and more fish on the end of your line. The water has really opened up, and fish are feeding actively on nymphs, with a few heads breaking through the surface as well. A few people have come back saying they beat 'em up on a variety of flies, including Blue Poison Tungs, Rainbow Warriors, Iron Lotus', and RS2's. Towards midday, a strong hatch of midges and BWO's has made for a good dry fly bite, with Sprout Midges, Smokejumpers, Para Adams, Sparkle Dun and Para Extended Body BWO all being top producers. Think 5x tippet with the flows coming up, and look for the tail-end of runs and slower moving water to hold fish. If the water is off colored at all, don't hesitate to throw some meat as spring runoff can be a great time for streamer fishing. Scupzillas, Buggers, Sparkle Minnows and Bellyaches all are producers.The Vrain is a good bet for the angler with a few hours to kill, or anyone looking for a fun spot to beat the crowds and catch a few fish. Last but not least, don't count out the lower reaches of the river as low as Longmont, where the streamer bite can produce some larger than expected fish for the determined angler who fishes slow and thorough.

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.
