and I think Doc nailed the other side of the coin. Now I moved toward flipping to Willapa Prime but honestly it would not make much difference other than to the hatcheries compliance with HSRG and then it is just a question how much effort. So the question around which is prime Naselle or Willapa is really about the hatcheries production & streams interaction and slightly improving Naselles chances of success. Either work I think.

To the question of how Willapa / North Prime helps Naselle. A contributing stream has a slightly lower requirement for straying and PNI than Primary. That is about it and the Naselle weir is prone to failure as posted before. That is about it in a nutshell.
