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

► If you take a close look at the mature BWO nymphs this month, you'll see that most of them have two light colored bands on the abdomen. That's why I recommend the Gold Ribbed Hares Ear over the Pheasant Tail at this time of year.

► These will become more important as the month progresses.


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

Bankwater, backeddies, slow runs: standard dry fly


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

Bankwater, backeddies, slow runs: standard dry fly

► Mahogany duns (genus Paraleptophelbia) create trout feeding activity in quiet bankwater because that's where the nymphs migrate before hatching. If you see trout languidly rising in slow water near the riverbank this month, you're probably witnessing a mahogany dun hatch.

► DON'T cast blindly. In this quiet water you'll spook the fish. Instead, watch the rises and pick a single trout. Use a downstream presentation so the fly reaches the fish before the leader and line.


Size 12-18 Soft Hackle, , Deep Sparkle Pupa. Body: tan, green; Shroud: tan

Riffles, runs, just below riffles: surface swing, shallow nymph


Size 12-18 Goddard Caddis, X Caddis, Parachute Caddis, Elk Hair Caddis. Body: brown, green, dark gray; Wing: tan, brown


Size 12-18 Diving Caddis, Soft Hackle. Body: brown; Wing: black

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

► Evenings may see hatches of caddis. Carry size 18-20 patterns.

► Small caddis pupa patterns drifted subsurface may produce trout for you late in the day.

► Caddis larva patterns (cased and uncased) in size 14 are an option. Drift them near the bottom.

► A few tan caddis should be expected.


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

► Adult imitations such as a Griffiths Gnat work, but it might be a good idea to carry some size-16 Renegades. Renegades look like two midges locked in amorous embrace, so trout--no romantics--figure it's a two-for-one real meal deal.


Size 6-16 Scud. Olive, tan, olive-pink, olive-orange

► Carry pink patterns or olive with orange.

► Scuds are light-shy, so cloudy days, mornings, and evenings are best


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

Bankwater with grass: standard dry fly


► Size 20 (and smaller) black nymphs are also a good choice.

► Cooler weather usually makes September a good rebound month on the Crooked.

► Expect heavy weed growth, especially in the slow-current areas.

► You might find that your nymphs will work better if they have a bit of flash. Try teaming a nymph such as a Lightning Bug with a pink or orange Scud, or just fish the Scud alone.

► If your nymph is too close to the bottom you'll be picking up algae, moss, and whitefish. So be near the bottom, but not on it.
