Best advice would be to fish it more than one night... sometimes there aren't many fish running through at a particular time... there are always fish in there somewhere though. The most effective method fo me has been jigging... you HAVE to have appropriate tackle though, a stout rod and a reel that can hold enough line to stop a strong fish in the current. 3-6 ounce jigs and put some time in listening to people and bouncing jigs, you'll find a few productive holes. If you're not into jigging... throwing bombers can be rewarding though usually on smaller fish.. and drifting eels around slack water can be excellent on the right night.
