I always get more strikes by facing into the current or crossing the current, as opposed to moving straight down with the flow. If I get a short hit or a solid hookup, I get GPS numbers on the spot. You’ll find that other fish can be near this original point of action, and once the bite does kick in, it goes off in short bursts. Keep hitting that section by repeatedly cross-trolling in wide, gradual back-and-forth arcs, or you can swing down-current and then move up-current through that section. Obviously, when the bite dies, troll to a new area.
