Hatches are matched from Westfly's database of "standard" fly patterns.


Size 16-20 Pheasant Tail, Hares Ear. Brown, brown-olive

Moderate runs, just below riffles: indicator, tight line, rising nymph


Size 16-20 Sprout Midge, Film Critic, Hackle Stacker. Olive-brown body, gray wing

Flats, runs, backeddies: standard dry fly


Size 16-20 Sparkle Dun, Comparadun, Hairwing Dun. Olive-brown body, gray wing

Flats, runs, backeddies: standard dry fly


Size 16-20 Diving Caddis, Soft Hackle. Dark body

runs, slowish riffles: surface swing

► Nymphs can be productive before, during, and after a blue-wing hatch, and even when there is no hatch that day. The key is to make sure your imitation is drifting near the bottom. To achieve that goal, you may want to team your nymph with a heavy fly such as a Kaufmanns Stonefly or beadhead Prince. You might want to look at Jeff Morgan's article on Tiny Flies for thoughts on these small nymphs.

► Emergers, duns, and spinners tend to collect in backeddies and slow margins, and trout often just wait there for them to arrive.

► Cloudy, drippy weather stimulates the ubiquitous blue-winged olives. If it's sunny, look for them in areas where shadows fall on the water.


Riffles, moderate-fast runs: indicator, tight line, shallow nymph


Size 12-14 Green Drake Cripple, Film Critic, Hackle Stacker. Light olive body, dark wing

Runs below riffles and moderate-fast runs: standard dry fly


Size 12-14 Comparadun, Sparkle Dun, Green Drake Paradrake, Hairwing Dun. Light olive body, dark wing

Slow-moderate runs: standard dry fly

► This is the smaller cousin of the big green drakes (Drunella grandis) that everybody got so excited about in June.

► This hatch occurs from the canyon area (below Pine Rest campground) on downstream. Flavs should be present through the first week of the month, then they'll be gone.


Size 12-16 Quigley Cripple, Film Critic, Hackle Stacker. Red-brown body, gray wing

Bankwater, backeddies, slow runs: standard dry fly


Size 6-8 Stimulator, Madam X. Body: light orange; Wing: tan

Bankwater near foilage: standard dry fly


Size 6-8 Stimulator, Madam X. Body: light orange; Wing: tan

► About half an hour before dark the October caddis will be most active and trout most receptive to imitations.

► You need the 6X or 7X leader on this river, even with a big bushy fly. This rig is no fun to cast, but it fishes well.

► Adults can be matched with a size 8 Stimulator, but the traditional orange pattern is a bit bright. If you're tying, try a browner body and a darker wing.

► If trout refuse your dry fly, dead-drift a pupa imitation along the bottom.


Size 6-8 Kaufmanns Stonefly, Rubber Legs. Tan, yellow-tan

Riffles, moderate-fast runs; just below these: indicator, tight line

► Nymphs are important this month. Two-nymph rigs, with a golden stonefly nymph on the point and a smaller fly on a dropper, can be productive when no hatches are in progress.


Size 10-22 Chans Chironomid Pupa, Zebra Midge. Black, gray, olive, red, creams, browns


Size 10-22 Griffiths Gnat, Sprout Midge. Black, gray, olive, red, creams, browns

► Trout can be very picky about size and color of the pupa. You may need to swap flies several times to find the right combination. You can speed up this process by fishing two pupa at once and noting which one the trout show more interest in.

► Be prepared for midge hatches at any time of day.

► When trout are midging, a Sprout Midge or Griffiths Gnat can work well, but a pupa pattern is always a good choice.


► For the first two weeks of the month, pale morning duns may be seen from noon on.

► Another sub-surface fly choice for October is an Egg Fly. Kokanee move up from Lake Billy Chinook, and a roe imitation can catch trout when drifted behind the kokanee.

► In the evenings, expect some cinnamon-colored caddis as well as olive-bodied caddis.

► Olive stoneflies are still available. Size 14 patterns are needed.

► The Cinygmula mayfly is another October emerger on this river. Match this cream-yellow insect with a size 16-18 Sparkle Dun, Light Cahill, or similar fly.


► This is an absolutely gorgeous time of year to visit the Metolius. The vine maples are wearing their fall colors in the canyon area, the air is crisp, and trout are available to persistent and careful anglers.

► Bull trout are also moving up from the lake and into the river this month. Large streamers are needed, such as a Morrish Sculpin.
