Out of curiosity what nymphs are you fishing there? Are you using caddis larvae? Try small size 18-20 olive or bright green caddis larvae. If you are not using them now your catch rates will increase big time! Flip over rocks and you should see tons of rock worms. There have been many everytime I have been there. Also, that stream is a caddis factory with so many species of various colors and sizes. I like that place a lot. Maybe I will try to meet you there in the near future.
