Best Methods/Flies if McCloud Is Turbid?

[Troutsource]

May be fishing the McCloud in the next few weeks. If it's blown with silt, one option is to fish elsewhere. But if I do fish there at higher turbidity, what is the best method? Bigger flies swung or drifted slowly? Heavy flash? Work the edges? Power Bait (joke)? Or does it matter? Thanks in advance.

When Googling I found several consistent pieces of advice:
1. If fishing in the middle, get on the bottom at eye-level for the fish
2. Fish the edges where there is more sunlight and fish can even spot dries on the surface. They'll feel more secure than usual on the edges due to turbidity.

...but inconsistent advice as well:
1. Fish bright colored flies, and flies with flash -- easier for the fish to see.
2. Fish dark colored flies, because they'll stand out better against the "bright" silty water.
