I doubt there is really anything that WA can or will do that will make a detectable impact on the whales.

It will take AK, BC, WA, OR, and CA working reasonably in concert to actually fix the problems that have driven the whales down.

The heavy lifting on habitat is probably from the Fraser south. The major fishery issues are from the Fraser north. But unless we deal with all the components, failure is the result.

One of the primary reasons for my pessimism is that. like salmon, there are a myriad of problems. This allows each problem-causer too say that "He's doing more damage, fix him not me". If we closed the ocean the whales still face the toxics and the Chinook poor FW habitat so fix those first.
