The Metolius River– There was a guy in the shop today about an hour before closing that said he ran in to a ripping good Green Drake hatch about noon today. This is yet another report of Drakes coming off earlier than we would often expect them, and from people I trust to know what the hatch is and when it normally hatches. When Tina and I fished on Sunday we saw Drakes from 2 to 4 near the hatchery, and that is the time I would most expect them to be on the water. 
But like any hatch, they do what they do, so be ready to fish Drakes anytime from noon to about 5. You might even see spinners about 9 or 10 AM and to see a Green Drake Spinner Fall is quite lucky. 
PMD hatches are popping on all sections of the river, and can be expected on the surface also from noon to about 5. It gets harder in the fall with the shorter days to predict them past 5, but it is warmer than usual so maybe….
BWO’s are on the menu, more often later in the afternoon and into the evening. When Fall Weather returns (soon I’m sure) they will be one of the most important afternoon hatches in October and November. 
To round out the mayflies Mahogany Duns are in their prime hatch cycle now and ought to be around another 2 or 3 weeks. Did you know Mahogany Duns are close relatives to the Pale Morning Duns? Both in the Crawler Nymph family, as duns they share the Crawler family attributes of shape, especially head shape, but 3 tails are an easy way to identify the Mahogany Duns. One of the flies I really like to use on the Met during the Mahogany hatch is a Quill Gordon, but a fly called an Upright Rusty Spinner and a Grey or Purple Comparadun or Grey Sparkle Dun in a #16 are all a great match for this important Fall hatch. 
Caddis hatches are awesome now, and there are a lot of them out to be on the lookout for. #16 Tan Caddis seem to be the most important, but October Caddis and Micro Caddis (could not be more different) and good numbers of a caddis that splits the difference, the #14 grey caddis that have been important for quite a while. We see these caddis pretty much all year. 
Stoneflies are equally diverse in sizes and colors now, and while the Little Olive Stones are waning quick, I saw fish this week that were keyed on them really tight to the bank line. It’ll be over for these guys once the next cold front come through is my best prediction, but until then, keep fishing that Henryville. 
Goldenstone dries: use both a Clarks Stone and Norm Woods Special. These are worth fishing from Wizard Falls up through the Canyon and from the Gorge up the Riverside Campground. Even if the fly is taken for an Oct. Caddis, who cares! 
Kokanee in the river big time now. Strangely, a lot of them are really black. We are not sure why, but I have a message to the regional fish biologist to try to suss that out. I have seen them darken at the time they are about ready to get the fungus that breaks down their bodies to river nutrients. But these Koke’s are new arrivals and are already black. Some Green/Red/Green fish too. Many fish already spawning so Egg’s in the drift mean adding eggs to your nymph game. If any of you have insights to the black colored kokanee I’d love to hear it. 
Big Black Kokanee also mean big streamers. We got ’em and if Bull Trout are your jam stop in for our custom tied Black Articulated Streamer or the Red/Black Dolly Llama that we sell for these short, but special weeks we have Red Kokanee in the river. Now is that special time.
