Lots of things come to mind .......Is the species predominantly black ? It will always be important to seek out heavy cover and direct structure fishing will be the standard for success. I love remnant cedar on the channels of old river channels!!! Percy Priest comes to mind for me. The deepest fish I have ever caught was in 63 ft of water there and it was almost like bottom fishing in the ocean..... Fish after fish after fish........
Thanks,
