Good news: after reaching well above-average flows of around 600-700 CFS during the past couple of weeks, BC is showing signs of starting to trend downward in terms of flow. Things will obviously still be up and down as weather fluctuates, with stretches of hotter, sunny days likely bumping flows again, but with flows down around 400 CFS there is certainly a lot of fishable water in play above Boulder Falls. Shop guides have also had some fun stripping streamers like a leech, wooly bugger, sculpzilla, or single sparkle minnow, and other larger bugs through some of the deep pools through town where the stream gradient flattens out. In the canyon, expect to still find fish stacked in the walking-paced pools and side waters. In terms of bugs, BWO have still been around -- Iron Lotus, Pheasant Tails, and Micro Mays in #14-18 are great imitations for these guys. We are also starting to see some other members of the Mayfly family show themselves, such as PMDs and the occasional red quill. Other bugs that will be in play on BC this time of year include caddis, small grey/yellow/green stoneflies, larger stones, and of course worms. If you're fishing dry droppers or single dries instead of a nymph rig, big patterns on top such as a Chubby Chernobyl or bigger foam hopper pattern in #8-12 can be great as we start seeing more and more terrestrial insects moving around on warm days.

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
