Bowfishing is perfectly legal on the chain. That is where I started. Did most of my fishing in ackermans channel and around grass lake. You will know when the carp are spawning around there. You can actually smell them. They start spawning in another month or so. Usually about the time when the water gets high after a few rains. And you can shoot plenty of fish without lights. Go out on really hot days and look for them around the middle of the channels and around the docks. The best ways is to get out right around sunrise and sunset and look for their backs sticking out of the water around the shorelines.
