Current Seam: How fish use this structure

A seam is a speed differential, not just a line on the surface

Two bodies of water with different speeds or directions meet, delivering food to the side where fish can hold more easily. The foam line on the surface is only a clue; the bottom seam may be in a different place. There are also boundaries within eddy backflows—don’t treat an entire slack-water pocket as a single point.

First observe drifting debris, then use the offset of your bait and line to confirm the target layer’s flow direction. Note the seam’s starting point, narrowest pinch, and where it fans out. Choose a segment you can pass through repeatedly, and avoid blindly casting only to the thickest foam.
