When trying to imitate baitfish on a river or stream, it is important to remember that bass, and river fish in general, are almost always faced the opposite direction of the current. This is due to the fact that bass often face upstream and let the current carry weak or injured baitfish down to them. In order to get your lure in front of the bass, it is important to cast upstream and let the current carry your lure down so that its action looks more natural.
