I was wondering the same thing. The WDFW webpage says "quota reached' for both MA 9 and MA 10, but is that accurate, or was it just 'season ended' in MA 10? WDFW reported only half of the quota caught a week prior to the end of the season and I didn't see very many fish being caught in the last week around Jeff Head/Shilshole. I would have preferred an extended MA 10 season over a 2 fish increase in the last week.

Relatedly, if you've ever seen the historical Ballard lock fish counts for Chinook, it's pretty clear that the tribes do a fantastic job of closing down the Chinook season in MA 10 a couple weeks (or earlier if quota met) before the Lake Washington Chinook return to the locks in healthy numbers. Would be nice to see an increased emphasis on carving out effective seasons (as opposed to just 'opportunity') in MA 10 in the coming years. 'Opportunity' is good for tackle stores and boat sellers. Effective seasons are good for families.
