The season of anticipation is over! That means the big stoneflies are out and flying in the Warm River to Ashton Reservoir section of the river.  Fish are still taking nymphs, but some are keying on egg-laying adults and will tend more to do so in the upcoming days. Look for the big bugs to be out soon below Ashton Dam, and depending on weather, look for a progression of their emergence on the river above Warm River.  Rubberleg patterns as well as any traditional large stonefly nymph pattern will work well, but as time goes by and fish key on more available adults, there is a huge array of effective dry patterns. All you must do is find that big, hungry trout and throw him or her any one of these!  All this being said,don’t forget that some fish may prefer caddis life cycle patterns.
