Back when the US/Canada (or Canada/US if you were on that side of the border) Treaty was proposed in the 80's, the WA Tribes were preparing was was called the "All-Citizen" lawsuit. In it, the 50:50 sharing would be between US citizens and the Tribes. AK refused to support the treaty if the Tribes proceeded with the suit as AK take of WA fish would count against the non-Indian share and that would essentially close a whole bunch of Chinook fishing either in AK or here.

Bill Wilkerson offered Co-Management if the Tribes would drop the suit. If memory serves, they got co-Management, did not totally drop the suit, but pulled it from pipeline. Perhaps to be reborn later.......... And, Wilk got his treaty.
