The Middle Deschutes is down to summer flows at 90 cfs today. March Brown hatches started last weekend and fishing is good on these meaty mayflies.
I won’t be surprised to see the 1st PMD and Pale Evening Dun hatches coming any day now too.
Caddis are certainly important and on the Middle D an X Caddis (Tan #14-16, Olive #16), a Corn Fed Caddis #14-16 and Iris Caddis #16 are great flies for there.
The Euro Nymph game is strong in there now, use smaller Brown and Olive Perdigons, 2 Bits, Frenchies and a myriad of patterns that can look like a March Brown, Including PT Soft Hackle.
Access includes all the Bend “town runs”, Sawyer park, Riley Ranch Park, Tumalo State Park, Eagle Crest, Cline Falls State Park, Tetherow Crossing, Lower Bridge, Steelhead Falls area and I am sure many other little secret getaways.
