I fished that area yesterday with only drum and catfish to show. I was mainly trying out new electronics (Lowrance Elite 5 DSI). I know that it is discontinued but is in my price range. The shad were so thick as you said I would snag several. Lots of boats under the bridge so I fished mainly the creek channel edges on the main channel side. I am sure we have crossed paths around the Brown's Creek area as I fish that area a lot.
