Every bass carries the same lateral-line hardware; the smallmouth puts it to a distinctive job: reading moving water. River smallmouth live by it — holding in the cushion behind a boulder, feeling the pressure seam where fast water shears past slack, and picking up the low-frequency struggle of a crawfish or shiner tumbling in flow they cannot yet see. That is lateral-line work, and it is why a river smallmouth can strike accurately in churned, foamy current.
In lakes the same machinery reads wind-driven current. A day of steady wind pushes real flow over points, reefs, and gravel bars; the lateral line tells a smallmouth which side of the structure the water — and therefore the drifting, disoriented forage — is moving across. This is the mechanism behind the oldest smallmouth rule there is: fish the wind-blown side. Calm, slick days flip the logic — with no current to read, the fish lean back on pure eyesight and get harder to fool.
One note on the division of labor: even at point-blank range the lateral line still helps guide the final strike, but a smallmouth typically arrives on target by eye first — the lateral line tells it where to hold and that something edible is coming; the eyes close the deal. A bait that both moves water and looks right beats one that only does one of the two.

FAQ
In river current, do smallmouth feed by sight or by feel?
Both, in a division of labor. The lateral line reads the current itself — pressure seams behind boulders, the vibration of prey struggling in flow — and tells the fish where to hold and that something edible is coming. The eyes then take over for the interception: river smallmouth typically tip out of a seam and strike what they have visually confirmed. Practically, that means a bait that both moves water (paddle tail, blade, crayfish kick) and looks right will beat one that only does one of the two.
