I went yesterday and caught 8 browns on a small streamer. On any other stream I would refer to what I caught as 2 fish and 6 dinks, but on the GP there are no dinks. They all count. Water was up, but was but not too high.
Had an ok day last saturday with snow falling and a really good day the week before in pouring rain w/ dries. The right fly to have would have been a #22 Blue Winged Olive, but a tiny griffiths gnat (w/ no peacock herl) or a tiny parachute adams seemed to work. I don't like nymphing there, but other people swear by it. For the last several years, I haven't really fished there much outside of December and March.
