The Middle Deschutes seems to have past Salmonfly season, but certainly is in the height of dry fly season with multiple hatches throughout the day and evening with PMD’s and PED’s and BWO’s and Caddis. I love a Purple Haze, Renegades, small Olive Stimulators, Light Cahill’s and Float & Fool’s. 
Soft Hackles and Perdigons and Caddis Pupa are the nymphs to focus on, and little Euro Streamers like a Brown Mini Gulp (Crayfish) will be smart options to tie on.
