For those of you wondering about the pattern I posted about, here it is. Like most of the patterns I use now, it's simple to tie and very effective for this hatch. It is essentially a pheasant tail soft hackle.
Hook: #12 dry fly
Thread: Danville 6/0 Olive
Tail: Dark pheasant tail fibers
Abdomen: Dark pheasant tail ribbed with copper wire
Thorax: Medium austrailian oppossum tied very buggy/loose
Hackle: Brown speckled hen dyed olive
Fish it dead-drifted like a nymph, but fish it through the drift so it rises as your line tightens below you. Depending on the current speed, I will place a #4 or 6 split shot about 6 to 8 inches above it on the tippet.
Sharpen you hooks!
