Here is a list of other baits/lures that can be productive:
Sierra Slammers, Tasmanian Devil, Green or brown Marvel Flies , Trout Teasers, Panther Martin, NeedleFish, Rooster Tails, and Bite-On Fury Shad on Powerbait.
I would suggest using some type of added attractant. Pro-Cure, Bite-On, Lip Ripperz and Berkley all make excellent attractants, which are sold at the general store.
Here is a list of recommended flies:
Dry Flies: Adams, Female Adams, Cutter's Caddis, Elk Hair Caddis, Stimulators, Black/Red Ants, Sierra Bright Dot, Royal Coachman and Hoppers.
Streamers: Wooly Bugger (black, brown, olive, or green), Mutuka (black, brown, olive, or green), Hornberg, and Muddler Minnows.
Wet Flies(Nymphs): Prince Nymph, Flashback Pheasant Tail, Hare's Ear, Zebra Midge (red and black), Copper John (red and copper) and San Juan Worm (brown or red).
