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

► 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.

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


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

► If your dead-drift adult generates no rises, try a little twitch. If that doesn't work, try skating your fly across the surface. This can be deadly in riffles, just below riffles, and along current seams.

► Often, the best plan for the October Caddis hatch is to dead-drift a pupa imitation along the bottom.

► 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. Another option is a Madam X with an orange-brown body. (On the other hand, I've used a yellow-bodies Madam X on small streams and did just fine.)


Size 16-18 , Deep Sparkle Pupa, Soft Hackle. Body: tan, green

Riffles, fast runs; just below these: indicator, tight line, shallow nymph


Bankwater near foilage: standard dry fly


Size 16-18 Soft Hackle, Diving Caddis. Body: tan, olive-brown; Wing: dark brown, black

Riffles, seams, backeddies below riffles: surface swing, shallow nymph, rising nymph

► These size 16-18 caddis are usually dark gray as adults. Adult patterns can be effective, but sometimes the most effective approach is a dark Soft Hackle presented on a surface swing, especially if you see concentrations of these caddis clinging just above the surface on the downstream side of rocks.


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 evening hatches.

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


► You may also find pale morning duns early in the month; look for evening activity.

► You may encounter Gray drakes. You can come close to matching them with a size 10-12 Parachute Adams.

► Size 16-18 tan, cinnamon, or brown dry flies will match most caddis. Hatches are heaviest in the upper river.


► While most of the steelhead are below Leaburg Dam, there can be significant numbers above Leaburg, between the Helfrich ramp and the lake. They can respond well to traditional tactics.
