The Northern California and Southern Oregon stock of Chinook have been hurting for quite a while. There has been a lot of work done on the Klamath River to return it to a better condition for the chinook. The Sacramento River and the Bay area is another area that needs attention, and it seems to be getting it. It's all part of the solution, but to solve the problem they need a broad multi-faceted approach that looks at ocean conditions along with the river conditions.
Back in 2009 they banned the retention of chinook up past Newport. It was reopened in 2010.
If the Northern Oregon/Columbia River chinook along with steelhead are to remain viable, ODF&W needs to take a serious look at banning commercial gillnetting on the Columbia. ODF&W has been incredibly stubborn about this.
