If you’re talking about dead drifting lures, sometimes that works with sluggos or surface plugs drifted On a slack line without drag In a river or in current. This works at night when baitfish May be resting inactive but swept along by the tide.
Another effective method is casting across or slightly down current and letting a lure (bucktail, darter, swimmer,...) swing down and across with the current. Sinking lures like bucktails will start to rise when they reach the point directly downstream from you. That’s where the majority of strikes will often come.
If you’re talking about fly fishing, do the same.
