How do I know if there are fish where I'm fishing?

What size hooks are you using? It sounds like a good spot and there is likely stuff there. I would try small hooks in the #14 range with a small piece of worm and see what happens. I've caught shiners and chubs up to carp with this setup. Big fish will hit a small presentation, but the opposite is usually not true. I would also try near the bottom as opposed to top water, but snags do become a problem.
