Snake River
Fishing on the Snake is off the charts at the moment with trout rising to a variety of dry flies and taking nymphs and streamers with voracity on all reaches.  PMDs remain the primary fare for fish, but they are complemented by claassenia stoneflies, hecubas, caddis, mahogany duns, as well as grasshoppers and some BWOs and crane flies.  It is a literal smorgasbord for trout right now.  Dry fly fishing is where it is at right now.  Streamer fishing is excellent as well.  You do not have to rely on nymphs, but fishing them as either double rigs or droppers off of surface flies can yield some very good results.  The morning hours is producing very good action, but it pales in comparison to what the afternoon is offering.  We cannot say that there is any particular holding water to target the most.  The simple fact is that everything is producing.  However, tight pockets on banks and structure, as well as the extreme head of seams and riffle line produce best in the early hours.  After 12pm, everything lights up.

South Fork
Flows from Palisades have been coming down over the past week and currently stand at just over 7900 cfs.  Trout have been displaced but there is still good fishing on every reach with the vigilant strategies and tactics.  PMDs are evident everywhere as are mutant stones.  There is also a lot of grasshopper activity, especially in the lower canyon reach and the lower South fork below Byington.  Going subsurface with nymphs is the best route to go, but dry flies are working in a lot of water.  Deeper portions of riffles and seams are producing with double nymph rigs.  The current margins of the same water are also producing with large attractors, particularly in the late morning and afternoon hours.  Banks and structure are fishing well with double nymph rigs and can produce with dry-dropper rigs with tight presentations.  Action on smaller dry flies is occurring in mid to late afternoon on riffles and seams with PMD and caddis imitations.
