The Upper Deschutes float from Wickiup down has been producing some nice catches of quality browns. This is trickier fishing than the appearance would give as it looks so flat and placid. The currents are moving at a good pace, and there is a lot of conflicting currents, so with a dry fly you need a good drag free float, and often very near logs that want to grab your fly, or suck it, plus your tippet underneath it. Damn those logs, but that’s where a lot of the fish are. 
With streamers pound the banks and logs and strip, strip, strip. 
We get 30 user days to guide up there and it’s open until 9/30, and it’s 100% fishing from the boat. A good option for the summer if you want to try it. 
Caddis and PMD’s are the main hatches. It’s been a few years back but I remember a float we did there on the 4th of July and having a good mid morning PMD hatch and the fish were eating a Patriot very nicely. Do you know that fly? It’s a variant of a Royal Wulff but has a pearl tag and hot pink body instead of peacock and red. I’ve had success with it during PMD hatches in many places for whatever reason.
