Flows have bumped down quite significantly over the past few days. From over 300cfs to under 20cfs. This will dramatically improve the fishing for the next couple of days. Don't delay going up there as this low flow scenario in the spring is not bound to last. Dry-Dropper would be best. A little more of a delicate presentation with the lower flows will be important 5X is fine. Up top think foam or general attractors: Chubbies, Stimis, hoppers, hippie stompers, 409's and Amy's Ants #10-16. As far as droppers are concerned, rainbow warriors, frenchies, iron lotus, p-tails sizes 18-14. Blue winged olives will be the major food source for these fish in the lower flows. If you find yourself in a situation with consistently rising trout: try a #18-22 para adams, para extended body BWO, sparkle dun, or Best Dry Ever BWO. All of these would be great options to get some fish to come to the fly. Look for the deepest water as the fish will be congregated early in the day. As the weather warms, look for fish to move into feeding lanes and riffles. Keep an eye out for caddis in the evening. Getting more and more reports of people seeing caddis throughout the Walker Ranch Loop. Stripping a leech and covering water quickly can be lots of fun during the days following a major drop in flows. The fish tend to turn the feed bag on as the flow goes down and often compete for food, that means chasing streamers. Get up there while the manageable flows keep the fishing good! Conditions are changing daily so be sure to either check the flows or call the shop for the most up to date flow information.

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.
