RE:Native-bearing tribs of the Snoqualmie
I haven't run into as many as Juro, but have had the pleasure of acquainting myself with a few unclipped (wild?) summers both above and below the Raging and one large buck that munched my purple/pink rabbit matuka on a very cold snowy day in early February several years back.
In talking to other flyfishers, there seems to be consensus that there are still good #s of native fish in the Snoqualmie system. It doesn't get near the pressure the Sky or Skagit do in spring (for whatever reason), but it has good fly water and some suprisingly big fish.
