This slide will be most destructive to sockeye, as they are so brood-line focused. Assuming iy is not fixed for this year's adults, that brood-cycle gets blown away. There will be some slop from age 3 and 5, if it gets fixed for 2020.

On the other hand, because of multiple age at return the Chinook, chum, and steelhead above that site can recover faster.
