Louie-
If you are not a fly tosser you can try the 'ol clear bobber and fly trick.
I use a 4lb outfit with a 4lb flouro leader. On your main line string a small clear bobber and terminate to a barrel swivel. Past the barrel swivel use a ~18" 4lb flouro leader to a size 16 or 18 dry fly (or nymph depending on season).
If you end up in the valley, there is a climbing and tackle shop in Yosemite village. There was this swedish lady that knew her sheet and was a good source for what was on the hatch. Check the local reg's because most of the valley is now C & R only.
My most productive flys were the mosquito and the royal coachman.
It took me YEARS to figure that place out. You now owe me a fish report....with pics
Good luck kiddo.
