The Middle Deschutes is great, the Stoneflies are out and I think we will see epic days and evenings coming up as soon as the weather get warm (or hot again) which is coming.
Until then, PMD’s and Pale Evening Duns as well as an Olive or Tan X Caddis and Corn Fed Caddis will cover a fair bit of the surface action you’d expect now.
I love Purple Haze and Renegades on the Middle D too. Add them in a #14 and 16 for the rest of the summer.
Euro Nymphing with a Brown Perdigon and a Jeff’s Improved B.A. Caddis Pupa will be very productive, and any nymphs that look like a PMD for the time being will be smart choices to tis on. PT’s, Brown Micro May or Tan 2 Bit Hookers are the best I can suggest.
