Hmm, I doubt if anyone actually knows, and the trout ain't telling.

But I suspect that it is by nose/lateral line. Even though the moving
water washes away scents, I suspect that the substrate continually
recharges the water with things that can be sensed by the fish.

I once lived downwind from a pulp and paper plant. Even though the
wind continually moved the odor away, it was always being recharged,
and was always there. I think the 'scents' in the water might be the
same.
