RunnGun,

The answer is that you don't get it in the Puyallup and Green with all that diking and flood control. Even before the recent nose dive in ocean survival these were marginal populations just barely making escapement (or slightly less, which is why they've been closed to fishing since the 90s). Those numbers weren't plentiful. They were just enough to allow CNR fishing, and have since become too low even for that.
