LB,

Allocation would be based on the forecasted return to coterminous US waters, same as they are now I presume.

Fish traps at Bonneville would not completely solve problems. Some number of hatchery fish need to be made available to the treaty fishery, and others need to go to non-treaty recreational in the mid-C, Snake, and terminal areas, and differing percentages of hatchery fish need to return as brood to their respective hatcheries of origin. I expect that even with the best of calculations and allocations some excess hatchery fish would still end up on natural spawning beds. However, the amount of control would be much greater than under current conditions. Near perfect would be having the treaty fish also harvested from traps at Bonneville and McNary.

That could work so well that ESA fish might even have a chance at recovery with the dams remaining in place.
