You can drift fish the flats up close to Culp Island with fresh cut shad if you can find them, they are hard for me to find on Ray Roberts, but if you can't catch any shad or bluegill, you can catch a lot of channel cats drifting out there with shrimp,
Just about anyplace you can find a flat with water that runs 14' - 35' will probably have some fish on it, You might try behind the dam to see if you can catch some shad, I went last week and didn't catch any, but they might be there now!!!
Good Luck to Ya!!!
