where i live there is about 9 lakes connected together. They are old rock quareys.  It is really deep and there are alot of bass, but are hard to catch.  what are some good lures that will work best.

deep diving cranks and t-rigged worms and jigs w/ crawdad trailer and slow rolling a spinnerbait

I dont kno if its the way you are suppose to but i have fished a rock quarey and what i did was fish the huge ledges with spinnerbaits and rat-l-traps hope this helps.

try jigging?

If the water is clear you might want to use natural colors/patterns

You might give spoons a try!!!

spoons and jigs.  try steep ledges, and look for unussual contour or structure on the bottom that would likely hold fish
