M.F. Snoqualmie

First post here and let me say this website is an awesome resource!

Fished the Middle Fork of the Snoqualmie Friday evening for the first time. Drove in about 8 miles and found some nice water. I fished mostly dries: 14 Stimulator, 16 PMD, 16 Elk Hair Caddis, 18 Royal Coachmen. Got several rises from very small fish, but nothing great. I noticed a significant hatch about 8:00 -- very small lighter colored flies. What were they? Any more advice for this stream? Also, I ran across a few large deep holes -- any advice on nymphs?

Based on the time of the year, I would guess that they were yellow sallies, a type of stonefly that hatches out midsummer around here, typically in the evenings.

You can do pretty well with any of the standard patterns for stoneflies tied in a yellow body. I never imagined that there was a need for a true yellow in fly tying until I saw my first yellow sally hatch.

Not quite related, but just slightly... on yellow type flies:

I was on the So. Fork Snoq. this Sunday up at the picnic area (for those that don't know, off I-90 exit 42 Ashel Curits exit, go over the bridge, right turn go straight to picnic area). Worked upstream from lot about 1/4 mile. Water level is very low now, so no waders needed - just "rock hop" to good casting positions.

Since it was very early afternoon, 3 to 5pm timeframe, sun still high in the sky; I opted for a #14 yellow humpy (with Wolff style wings).

Excellent in the pocketwater, high floating, last well through several C&R's. Most fish are small in this area, 6" average, but I did get a nice 10" cutt who just waited in a seam for a meal.

I'd agree that the PED is a likely yellowish/cream colored mayfly that inhabits these waters also. However, I had to depart early and never got a time to fish the PED or caddis of dusk. I would recommend the Humpies in yellow, florescent green and red as attractors during the bright sun. The fish don't seem to care, as they are very oportunistic for a meal in the somewhat sterile westslope streams.
