The St. Vrain through town in Lyons and north up US 36 are worth a look right now, especially considering that other waters like the Big T tend to get more attention this time of year. Last I looked, the waters over by Lyons looked high but clear. If nymphing, try leading with something like a squirmy worm, small black leech, or bigger stone such as a Girdle Bug or Tungstone in #10-12. Drop to smaller, flashy stuff like rainbow warriors, blue poison tungs, copper johns, flashback PTs, etc., in #14-16. We're also getting toward the time of year when, with warming temps, the metabolism of these fish will be kicking into gear and they'll be willing to move a bit to eat a fly. We're not quite into the hopper and terrestrial bite yet, but it's still worth leading with one of these bugs if you're fishing a dry dropper in foamy back eddies and slow pools. Final hint: streamers can be a lot of fun up the north branch below the dam when the water is up.

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
