I would expect to start catching blacks all over Blood in around 3'-5' of water close to deeper water right up tight to chunk rock banks. Seems like once water hits 54 degrees you can smoke em like that, lots of fun too. Try the smallest cork you can get away with a 1/16 oz jig, purple and char works best for me. Run the jig about 18-30" under the cork and jig it back to the boat. My kids LOVE fishing like this.
