right now good bet is to head out ninja early and tie on a big foam stonefly imitation - any fly shop around here will have them, though I'd bet the supplies are running low. stalk up banks with a slow flow and deep water and you will get some vicious takes. when I mean early though, I mean 4am.
it'll be good for another week or so, maybe more, on the golden stonefly hatch. best action 4am till 9 or so, sometimes later. overcast days action was all day, like yesterday.
for nymphing look for choppy water riffles against the main hard river current. The waves will look like little diamond shapes. That's seriously trouty water when u find it.
Enjoy the Bow!
