The Middle Deschutes is a great place to spend the morning and early afternoon or head out after work and fish until dusk. 
You’ll find a diverse set of hatches that could vary by river mile and area you choose. Tan Caddis are quite ubiquitous through the areas from Bend to Billy Chinook. Pale Evening Duns and PMD’s will be too. BWO’s might be more isolated but just like what I said on the Metolius report, the evening shade hatch is a real deal, and you need to look for these tiny mayflies in the summer too. I think a lot of us forget about BWO’s in the summer and think of them as Fall/Winter/Spring hatches, but that is not the case and they can be the frustrating hatch you can’t decipher because you either don’t notice them, or you didn’t expect them. 
Of course the nymph fishing, especially with a tight line mono-rig (euro) is going to be awesome.
