Ditto to JDC - I mostly use scuds (size 12-20 - smaller on sunnier days and during midday). I typically use gray or brown, and tie some weight into them, below an indicator. San juan worms as well, in brown or red. Careful wading near the dam - if you hear a horn and see everyone else heading toward the bank, feel free to join them. I always carry very small dries (usually gnats, ants, adams and olive dunns in a 20 or 22), in case I see fish sipping off the top. Not a lot of people target fish taking dries, particularly around the outlets, but it's been very productive for me in the past - my largest Taney rainbow (a meager 23 inches, but thats good for me) was taken on a size 20 black ant near the dam.
If the water's up, give Lilley a holler - Friends and I have rented a jon boat from Lilley's in the past, and had a blast, though drifting powerbait, not flies. I know some folks drift small micro jigs along the bottom and under a float from boats, but I've never tried it.
