The Lower Deschutes has been exciting with the good steelhead run coming up this season. I am really optimistic for our October and November trips in the day stretch for steelhead! 
Right now most of those steelhead remain a long drive from Sisters, and are faint below Maupin to the Mack’s Canyon area and all the way to the Mouth of the Columbia River. A lot of friends have caught multiple steelhead this season already on swung flies! If the rain we are having this weekend creates runoff from the White River Glacier, keep an eye on that for a few days. Amy in Maupin at the Deschutes Canyon Fly Shop does an excellent report to keep tabs on that aspect of this game. 
Swinging Purple flies like a Street Walker, Freight Train and Berry’s Peacock & Purple is as good as anything. Green Butt Skunks are tradition on the Deschutes and must be in every fly box. If the water stains from the glacier, bump it up to an Intruder with some flash in the body for better results. In perfect water conditions swing and skate a Muddler. One cool trick with a Muddler is make your own steelhead leaders from Maxima using 25#, 15# and 10#. between the blood knots on the 15# section put on a Muddler or an Andersons Euphoria so it slides between the blood knots. One tip though, make sure you put that slider fly on the leader with the hook bend UP towards the fly line (not towards the point fly) because when it turns over on the water to begin swinging the hook point will be under the water instead of above it. 
For Trout on the Warm Springs to Trout Creek drift we’ve had good morning caddis hatches and dead/spent caddis dry fly fishing. By afternoon look in the eddies for spent mayflies and caddis, and even ants, beetles and midges. Some of the eddies hold brilliant surprises. 
It seems like the main hatches now are #16 Tan Caddis and #14 Pale Evening Duns. With that said, don’t forget #16 PMD and #20 BWO’s.
Nymphing is good with Berry’s PCP, Brown Perdigons, Girdle Bugs, TJ Hooker, Caddis Pupa including Tan #16 and Grey #18, Soft Hackle PT and Red Ass Soft Hackle, Guide Hares Ear, Micro Mayfly to match BWO and PMD’s and 2 Bit Hookers to match BWO’s and PMD’s.
