Major Hatches for October

Importance by half-month
 Super    Major    Minor    Slight    None

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.

► 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.

Nymph

Size 12-16 Hares Ear, Pheasant Tail. Dark brown, olive brown

Slow-moderate runs, bankwater: indicator, tight line, shallow nymph

Emerger

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

Bankwater, backeddies, slow runs: standard dry fly

Dun

Size 12-16 Comparadun, Sparkle Dun, Hairwing Dun. Red-brown body, gray wing

Bankwater, backeddies, slow runs: standard dry fly

► These mayflies migrate to slow water before emerging, and hatches usually take place in the slow margins of the river. Trout are in no hurry to sip the duns, and rises are usually lazy, head-and-tail affairs. Because the action is in quiet water, your approach and casts need to be stealthy. The best strategy is to wait until you see a rise, then cast to that trout. Blind casting usually just puts the fish down. Let your cast settle gently on the water and avoid lining the trout. You may need a downstream presentation.

Pupa

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

Adult

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.

Adult

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

Bankwater with grass: standard dry fly

Adult

Size 2-8 Muddler, Woolly Bugger, Clouser Minnow, Possie Bugger. Browns, olives, silver, greens

Lakes; rivers over gravel and cobble, undercut banks: count-down-and-retrieve, slow retrieve, wind drift, deep swing

► When fishing the slackwater pools when there is no hatch, try an intermediate line and a streamer pattern, such as a Morrish Sculpin, Woolly Bugger, or Clouser Minnow; focus on deeper water near rocks.

 

October Tips

Trout


► Don't be put off by the murky quality of the water.

► The flows should drop as the irrigation season comes to an end.

► Look for brown trout in the slackwater pools, and rainbows in the riffly areas.
