I've fished an inlet that sounds similar to this, there was a hatchery at the head of the inlet and the kings would stack up before spawning, if you hit a tide change early in the morning you "might" get them to take herring otherwise the only thing else that seemed to work were plugs and spoons, namely, a tomic 169 (any color as long as it had a white body with a green stripe) or Superior spoons (chrome and brass) either of these trolled fast, about the only thing that consistantly worked for me. good luck.
