Well it is fall on the San Juan, the cotton woods are a bright yellow, and as usual the fishing is great. I have been having good success on gray and cream midges in the morning. After lunch chocolate baetis have been the best. I have caught some fish on gray and olive but most fish are looking for the darker mayflies. If dry fly fishing is your thing this is a great time of year. The midges have been clustering. For some reason they do this more in the fall than any other time of year and the fish know it. A midge cluster pattern will work well. You can also do well in the afternoon with blue winged olives. The mayflies have started and the fish are looking for them. You will do the best around 1:30pm anywhere from t-hole down.
Good luck, Chris
