LB,

Some wild fish will die, but not enough to be limiting. In the absence of significant ESA mortality, the usual legal guidance will set allocations, presumably along the lines of 50:50. Non-treaty allocation between sport and commercial would most likely be set according to respective political influence.

Freespool,

It isn't about what is or isn't absurd. Some people think that treaty fishing rights in the 20th and 21st centuries is absurd. It's about what's adjudicated unless the tribes assert otherwise, and the states do not object. If OR and WA are not objecting to treaty fishing downstream of Bonneville, it's probably because they have concluded that the tribes would prevail in adjudication. But it hasn't happened yet.

Todd,

Although improbable on the Columbia, it's technically possible.
