The Lower Deschutes is fishing well for trout on the day stretch from Warm Springs to Trout Creek, or walking in from Mecca or Dry Creek. I was talking to a few of the Lower Deschutes guides on the FFP team yesterday and they all said caddis. Caddis Pupa. Caddis Emergers. Caddis Adults. Caddis Egg Layers. Troy said he’s getting fish to eat Caddis dries in the morning, but by mid-afternoon it changes to pupa’s fished deep. Michael also has been having good success on PMD Nymphs like a Split Case and Micro Mayfly #16’s. Berry’s PCP was born on the Lower D and is the brainchild of one of our good friends Bruce Berry. It needs to be on your leader down here. I also wat to say how cool it is that Sequoia has begun to use her drift boat as a guide on the Lower Deschutes day stretch adding another place she offers trips. 
My good friend Chester is a Deschutes fanatic and he walks in from Mecca several evenings a week. I know he’s been finding success on Caddis & Pale Evening Duns, and has recently experienced a nice session with a PED Spinner Fall in an eddy a few days ago. Our #14 Winna Spinner is the fly for that. I would also throw some #16 Upright Rusty Spinners, Purple Haze #14-18 and Fin Fetcher Caddis #16 in your fly box for visible flies to use just before dark. 
Look for fish in the eddies to be rising, even in the afternoon. Don’t forget to fish in the shallow riffles as we often get too focused to the deeper runs for nymphs, but the spots that are shin deep can hold a lot of trout on the Lower D this time of year. It’s where the food is in a lot of cases. I’ll never forget lessons from Matt Klee and Dean Smith on shallow water here. Trout feed in shallow places if that is where the food is.
