For beginners I would go with mepps 00 agilia. If you have a bit more patience. Tie on a #8 eagle claw baitholder hook and attach 2 split shot about 14 to 16" above the hook. Attach pink/rubber floating powerbait to the hook. Throw this rig out upstream and let it bounce along the bottom in the current downstream.
When you feel several sharp taps/bites set the hook as hard as you can a reel like crazy.
Good Luck.
