River Statistics:
Boulder Creek is consistently fishing great from town almost all the way up the canyon, although you'll still find skinnier water up towards Castle Rock. These stretches of cooler weather we continue to have mean the runoff hasn't really kicked in full force yet on the creek. Once it does, stonefly nymphs are a favorite pattern, as are squirmy worms and flashier attractor nymphs like rainbow warriors and frenchies in relatively bigger sizes (#12-16). Even now, you can have some success fishing these sort of spring/summer bugs below Boulder Falls. The Chubby Chernobyl has been doing damage in pretty much all colors as always, as are stimulators, parachute adams, other assorted terrestrials like smaller hoppers and beetles, etc. Caddis are starting to be out in a major way, so caddis patterns like the graphic caddis, Z-wing, tungsten swing caddis, are a great bet right now on a dry-dropper rig (and don't forget about the elk hair caddis on top). Euro nymphers should be able to have a great time in the creek right now too as the waters are on the rise. If you're looking for a change-up from fishing dries and dry-droppers in the canyon, head down to the stuff out east with a small streamer. As long as the waters aren't complete chocolate milk after a rain event, you can get some nicer fish to chase a streamer.

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
