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


Nymph

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

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

Emerger

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

Flats, runs, backeddies: standard dry fly

Dun

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

Flats, runs, backeddies: standard dry fly

Spinner

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

runs, slowish riffles: surface swing

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

► You may find morning hatches and pick up some resident (smaller) trout on surface or emerger patterns. However, the big fish will be much more receptive to the small leeches and streamers.

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

► 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.

Pupa

Size 10-22 Chans Chironomid Pupa, Zebra 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.

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

Adult

Size 4-10 Madam X, Daves Hopper, Morrish Hopper. Tan/yellow, olive/yellow, green

Bankwater with grass: standard dry fly

Adult

Size 2-10 Woolly Bugger, Bunny Leech, Hale Bopp Leech, Possie Bugger. Black, browns, olives

Lakes; backwaters and slow sections of rivers: count-down-and-retrieve, slow retrieve, wind drift

► Use a small (size 10-12) Hale Bopp Leech, Woolly Bugger, or similar pattern in olive, brown, black, or burgundy. A jerky retrieve works best: after quartering your cast downstream, pull in a few inches of line, then stop for two seconds, then repeat. Use a full-sinking line.

Ant



Adult

Size 10-16 Parachute Ant, Ant. Black, brown, red-brown

Trout


► Set your expectations: this is not the prime time to fish the Williamson. While large fish are available, they are tough to catch in the upper section and are very wary. Most of the migratory rainbows will be above Chiloquin this month.

General


► It seems to me that this region cools down faster than any other part of Oregon, so an October cold snap can definitely slow the fishing. Don't wait too long to make a trip.
