Early June is usually a damp and uncertain time for Oregon weather, especially on the west side of the Cascades, and particularly in the northern part of that sector. If it's time for Portland's Rose Festival, don't leave your raincoat at home. Stable, summery weather doesn't start until the fifth of July.

So be prepared for anything this month!

The salmonfly hatch should be in full-steam on the lower Deschutes, but just starting on a few other rivers. Most rivers that have salmonflies also have golden stoneflies , although there are exceptions. When both bugs are available, trout usually prefer the goldens, so be sure to carry size 6-8 patterns in golden stonefly colors as well as big size 4-6 orange salmonflies imitations.

If you find trout unreceptive to your salmonfly/golden stonefly offerings, try a submerged adult, such as the Titanic Stone , presented on a surface swing. For other details on fishing the salmonfly hatch, see Fishing the Salmonfly Hatch.

The big bugs aren't the only things going down the river this month. There are other hatches, and there are many times that trout will bypass a salmonfly and sip tiny PMDs or caddis instead.

Pale morning duns hatch in profusion on some rivers, and while trout get very selective on them, it's not a difficult hatch to match. Duns and emergers will both catch trout. Often, trout will switch from nymphs to emergers to duns, lingering longer on each stage than most anglers expect. A size 18 Parachute PMD or Sparkle Dun works just dandy when trout are on the rise. On very clear, slow streams you should switch to a CDC Cripple , PMD Cripple , or No Hackle with a pale yellow body. In this latter case you'll probably need to use a 6X or 7X tippet and a downstream presentation so the fly reaches the trout before the leader. No Hackles don't hold up very long; two or three fish, and the fly is too shredded to use any more, so the Cripples are preferred (by fly anglers, at least!).

Yellow quills (Epeorus mayflies) have a surprising habit: the dun generally emerges underwater. The dun then floats to the surface, where it dries its wings. In our area, trout prefer to take them while they're still underwater and shun the duns on top. Therefore a good fly choice is a yellow-bodied Soft Hackle in size 14 or 16 or a downwing wet fly. Some anglers confuse this hatch with the PMDs because they occur at the same season and both insects are yellow. The Epeorus, however, is bigger and has yellow wings, rather than smoky gray. Epeorus nymphs live in riffles, so duns (and trout) are usually found just downstream from a patch of whitewater.

Pale evening duns are members of the clinger group of mayflies, hence they are usually found hatching near riffly water. They have a yellow body that is a bit more intense in color than a PMD, and the wings are tan. Try a size 12-16 Light Cahill or yellow-bodied Sparkle Dun to match it.

Saddle-case caddis , spotted caddis , and green caddis are all June events, too.

Steelhead are starting to move into coastal streams that support summer-run fish, such as the Wilson and Siletz. They should soon reach fishable numbers. It's still too early to find many fish in the Deschutes and North Umpqua, which usually don't turn on until mid-July. The Hood River gets an early run of summer steelhead.

Callibaetis mayfly hatches will be common on many lakes this month. Hatches usually occur late-morning to mid-afternoon. For several hours before the hatch, trout will feed on swimming nymphs. Cast your fly and retrieve it very slowly--extremely slowly, incredibly slowly, half-an-inch-a-second slowly--using an intermediate line with a long leader. A Flashback Pheasant Tail , size 14, should work quite well. During the hatch use a Callibaetis Cripple , Sparkle Dun , or Comparadun and a floating line. If the wind is too strong for a surface fly, go back to the Pheasant Tail .

Trout will also be feeding on midges . Look for hatches at midday and in the evening, and carry midge pupa patterns in a variety of colors including tan, brown, black, and olive. The static midge tactic should work well most of the time. An adult midge pattern, such as a Griffiths Gnat , can work well, too. In my experience, the productivity of a Griffiths Gnat is in proportion to the elevation of the lake: the higher up the mountain I am, the better the Gnat works. I've never met anyone else who makes this claim, but I still believe it.

With warmer water, dragonfly and damselfly nymphs become active and are taken by trout and other fish. Dougs Damsels and Marabou Damsels work well for the latter.

It's hard to go wrong with a Woolly Bugger or Seal Bugger on a slow-sinking line, such as an intermediate or Type 2.
