Flows are trending downward overall on the Collie right now since the more off-color flows due to the infusion of moisture earlier in October. Smaller bugs and streamers have been the ticket, with the peach and yellow-colored egg bite reportedly being really kicked in up around the Pumphouse to Radium stretch. Productive bugs on the nymph rig have included smaller Girdle Bugs, Sparkle Wing RS2s, Flashback PTs, Mercury Black Beauties, Purple/BWO JuJu Baetis, Copper-Ribbed Foamback RS2s, Drowned Tricos, etc. A recent float trip on the lower CO down toward Glenwood Springs also found some excellent mid-afternoon dry fly action as fish sipped #18-20 Extended Body BWO dries in side eddies. Our guides have had some awesome outings in the area above and below Parshall recently, both on the Colorado and on the Williams Fork. Crowds have been bordering on a little crazy at times on the beautiful fall weekend days, so definitely try to get out on the Willy's during the week if you can. Streamers have been the favorite overall tactic for us, with best results when temps are cool and light is low (cloud cover/early and late) -- no surprise there. Be sure you're pinning your streamer tight to the banks and along structure and are giving it at least a second or two to get down into the danger zone before putting action into it. White is rarely a bad choice when you're tying on a streamer at the Collie, but definitely switch it up and throw some olives, purples, blacks, etc., at them if you're not getting follows. Sometimes the old adage of "dark day, dark streamer" seems to really hold true.

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
