The Middle Deschutes has no confirmed Salmonfly hatch yet, but my feeling is if you were down near Steelhead Falls this weekend you’re going to see the 1st of the juicy bugs, at least hanging on the stream side vegetation. By this time next week it should be in full swing.
What is happening is PMD and Pale Evening Dun Mayflies (depending on time of day) in the afternoon and evening, and quite a few tan caddis that a #14 or 16 X Caddis or Elk Hair Caddis or Corn Fed does the trick to match when that hatch is on.
Renegades, smaller Stimulators and Purple Haze are fun attractors that get the job done on the Middle D and of course there are brilliant moments of nymphing and using small streamers either on a tight line leader set up or stripped on a floater or even a light sink tip.
