I second the worms. Definately troll - but use worms if you want faster action.

This lake also fly fishes well. Black or olive wooly buggers have worked best for me.

Vary your speed and depth to see what's working best. Somestime fast is what gets them, other times drifting with the wind is all you need.

Good luck and post a report.

I'm heading there tomorrow morning so I'll let you know how i do.
