Finicky bass, in a creek, help!

[Backwater Charlie]

So, I've fished in this creek, I don't know, 2 years straight. I have used all kinds of lures, flukes, plastic worms, spinnerbaits, even poppers. Except for the 2" grub, which I hooked two fish with, NOTHING works! And even the grubs doesn't work anymore! Just that one fishing trip! It is around 12' deep at it's deepest point, and is filled with 10-12 inch bass, and they're have even been a 17" bass in they're but some bone head I know caught it and then took it home . But back to the fishing, I can see a few bass here and they're swimming every now and then, but they bite NO lures consistently. Anyone got any recommendations. Maybe some of those Rage Tail Shads? Or would that be a little too big for the area? The grub I used was a crayfish pattern so I am thinking they're feeding on crayfish. The creek is very clear by the way, it's water clarity is around 6'. They're are a few fallen trees in the water too.

If you need any more info about it just let me know.

So, what lure do you think I could catch these lock-jaw bass with?
