You'll still find some golden stoneflies in the upper part of the river this month. A few pale morning duns may be found as well. Both hatches are on the way out.

These hatches will be replaced by microcaddis, mahogany duns, flavs, and blue-winged olives. See Mahogany Duns for details and tips on mahogany duns.

Flavs are the small western green drake (Drunella flavilinea or Drunella coloradensis; the two species are hard to tell apart). They should show up around mid-month. Flavs are the smaller cousins of the big green drakes (Drunella grandis). Use the same patterns as for the big green drakes (Poxyback Green Drake for nymphs, Green Drake Cripple for duns) but in sizes 10-12. This hatch occurs from the canyon area (below Pine Rest campground) on downstream.

Expect to see blue-winged olives on the river this month. Use a size-18 Sparkle Dun, Baetis Cripple, or Parachute Baetis during the hatch, and a Pheasant Tail or gold-ribbed Hares Ear nymph when there is no hatch. If you hang around until evening, expect spinner falls of blue-winged olives; a size-18 Rusty Spinner should do the trick.

Some size 14-18 caddis can be expected near dusk, with the smaller caddis being dominant. Evening fly anglers should try a size-18 olive or gray X Caddis.

An overlooked hatch here is yellow sallies. They can hang around for most of September. A size 14-16 Parachute Caddis or equivalent, with an olive body, will imitate them. Some October caddis may be active by the end of the month.
