Here at Lake Cumberland we put out lights and them come to the lights at about 5:00 am. The thread fin shad are the ones you ususally get from this .The shad are drawn to the light and you can throw on them. I can put a light out at a boat slip in the marina and usually have plenty of bait for several fishermen! If we want alewives we have to go out into deeper water and put out a light and let our net sink to around 65 feet. You also have to get up alot earlier to get the alewives! I don't know if this will help you at that lake, but thought I'd just throw it out there. Good luck!
