Welcome to the best FF'ing site on earth cal...try running some streamers down stream and across. keep hte rod tip low, pointing at the line, mend to keep it all straight between you and the sunk fly and hang on right when the fly swings across the river downstream from you..pause at the end of the swing and wait a couple of seconds then 'inch' the fly back to you for a few pulls then cast again. You might be surprised. Good luck !

Cheers,
