You need to find docks or pontoons that are close to the river channel banks, then seek out the darkest part of the dock, especially those that are 15-30 foot deep. Are u using colored line? If not you need to invest in some, that the best thing since sliced bread for dock shooting. Learn to watch your line, most all bites you will not feel, you will only see your line twitch, or jump, then set the hook. Make sure you are using a 1/24 or 1/32 oz jig head.
