The Stone has been fishing well. You can catch em nymphing, streamer fishing, or on dries. Lots of Baetis down around Livingston. If your nymphing, Pats or TJ's are good top flies along with a zebra midge, egg, rainbow warrior, squirmy worm or a perdigon. Larger articulated streamers have been getting some attention. Water levels remain low allowing for some good walk/wade fishing.
