Water is high in the park drainages, but there are some great times to be had on small streamers and shorter nymph rigs up here right now. Many fish will tuck down deep and take refuge in the moraine cutbacks during runoff season, but you'll also find good numbers of fish stacking up and holding in the side eddies and flooded backwaters. Take a "fish the edges" and structure approach, looking for water with that magic combination of depth and slower, walking-paced current speed. Dry-dropper rigs with squirmy worms or small leeches under stimulators and chubby chernobyls have been really producing on Glacier Creek. These fish are hungry as the bugs really start popping in spring, and will pounce on a flashy bug like a Rainbow Warrior in #14-16 or a Tungsten Swing Caddis in #14-18. Even with flows up, remember that these are wild fish and are wary of their surroundings -- particularly the bigger ones. These fish will definitely not be too picky when it comes to what they eat, but the water is not huge so don't expect to catch a bunch romping around everywhere. Fish it with a conscience! Give the shop a call with any questions regarding access or where to fish.

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.
