The Crooked River is just darn good, mostly nymph fishing with PMD Nymphs but also Dry Fly fishing on PMD emergers, duns and spinners.
Midges and Caddis are certainly in the mix of other hatches that should/will create dry fly and nymph fishing opportunities.
If you are headed out there make sure you have a Tan 2 Bit Hooker and a PMD Split Case Nymph on the line! I’d euro that, but a NZ Wool Indy is a good way to approach that too. Water levels are awesome at 260 cfs and reservoir levels are holding up well. Generally not too smokey from day to day on the Crooked.
The Metolius itself has been in the smoke, but on and off and the AQI has generally been better there......
