It would take oversight with balls. The idea is that the Tribes would get first call on some level of harvest since they are owed actual, real fish and not paper fish.
What will likely happen is the State will simply abandon steelhead and then salmon and then crab to the tribes in order to allow continued growth and habitat destruction. That, and to continue the flow of campaign funds.
Oversight by whom? Clearly the State has no control/authority over the Tribes and the Federal Gov't seems to have forgotten that it entered into the treaties on behalf of its citizens at the time. It would be nice if they (the Feds) grew a set and ensured that the tribal Governments adhered to the terms of the Treaties and subsequent Federal Court rulings.
Sorry to be such a naysayer but I seriously doubt that any of the individual tribes will relinquish any of their actual or perceived treaty rights.
In fact, just look at how the Suquamish Tribe has delayed the Point No Point ramp development for over a year by merely objecting to the issuance of a Corps of Engineers permit on the basis that usage would adversely impact the Tribe's ability to exercise its treaty rights. No details, just the assertion is enough for the Corps to withhold the permit.
