The Crooked River is still one of the hottest spots in Oregon to be fishing now. I don’t see this slowing down until really cold weather comes this winter. 
PMD hatches continue to impress us and add increasing numbers of Mahogany Duns and BWO’s to that and you’ll usually have afternoons filled with a lot of dry fly options. 
It won’t all be on the dry fly of course so think about matching the cycle of hatches and have #16-18 Brown Mayfly nymphs, #18-20 Olive or Black Mayfly nymphs and a lot of Midges, Scuds and Perdigons in your box. Our Tungsten Micro Mayfly Nymph selection is on point for this fishery
