Yesterday we had a guy come back to the store who was wild eyed and excited and oh so appreciative of last weeks fly recommendations on the Metolius River Report. He beamed with his story of 9 trout landed on the caddis we recommended on the report. 
Last night I texted my friend and customer Bobo (he’s usually the guy on the rover searching the river for something he dropped, or limping back to the truck after falling over something HAHAHA) to see how he liked his new Korkers boots (he did) and he told me he’s been having good success on the Golden Stones in the Upper River. It’s a great time for Golden’s all month so make sure to fish a Clarks or Norm Woods over the next weeks! 
PMD’s are out all over the River from the Headwaters area to well below Bridge 99. It is a staple summer hatch and one you want to make sure your boxes are covered for the nymphs, emergers, cripples, duns and rusty spinners. 
Blue Wing Olives are a common hatch in August and get better throughout the month. Usually we see these little olive mayflies later afternoon and early evening and a #20 or even #22 is a good hook match for this hatch now. Same idea to have the nymphs, emergers, cripples, duns and spinners for the BWO’s. 
August is a great caddis hatch month and besides the #16 tan caddis that are common on nearly every western river and stream, look for #16 to 18 olive caddis (Iris, CDC and Hemingway) and any day now we will see an explosion of yellow micro caddis that are a #20 (maybe 18). The fish love this hatch, mostly because of how strong it is there is a lot to eat. 
Midges #20-22 and Yellow Sally’s #16 and a #14 Olive Haze are a few other dry flies to carry this week. 
This is a topic that comes up in the shop often enough I want to say something again about it here, in a river like the Metolius fluorocarbon tippet on the dry fly rig is not your friend. It sinks in the film and adds micro drag to the drift. Micro drag is a no good killer of what appears from your end to be a good presentation. From the trouts sightline, it stinks. Micro drag stinks. Use a nylon tippet on the dry flies in tricky currents like the Metolius. 
To note, I use fluorocarbon tippet for dries in lakes, and usually even use it on the Fall River. But the Met has currents designed by the Devil himself and it’s hard enough to get a good drift when everything is all perfect. 
When you nymph or streamer fish here, the fluorocarbon has advantages. Stronger test, better wet knot strength, more abrasion resistance and way more invisible. 
So when you are running nymphs like Caddis Pupa, Jig Napoleon, Frenchie, Walts Worm, Olive and Purple Perdigons, Zebra Midges, Micro Mayflies (PMD and BWO) 2 Bit Hookers, Golden Stones, Green Drake Jig Nymphs, Twenty Incher and Soft Hackle Pheasant Tail, utilize fluorocarbon tippets in 4x, 5x and 6x for the best results. 
There are some really nice Bull Trout in the River now and for the most part we’d chase them with a big streamer on the swing, possibly stripped too in some of the pools. Dead Drifting streamers under an indicator or on a tight line nymph rig is good in some quarters too. Read your waters and choose how to approach it by what you see and what you feel.
