The Lower Deschutes trout action is good, our guides are seeing good morning nymphing action, extending to the afternoon and then seeing a slot of caddis, decent PMD’s, some straggler Pale Evening Duns and midges. In the afternoon look for bank feeders under overhanging trees and especially in eddies. In the evening dry fly risers will be in a lot of water types from riffles, runs and eddies. 
The fish seem to be looking for small black stonefly nymphs now. So a Girdle Bug with a Caddis Pupa dropper is a great combo. Flashback PT’s, Perdigons, Jigs, Copper John, 2 Bits and Split Case Emergers. Warm Springs to Maupin is all good.
