The proposal is simply to stop planting the Mckenzie and manage it for wild fish, including a bait ban (as it inevitably kills wild fish). As far as I know the guides Assn. is against this proposal (uncertain how it would affect their livelyhood) and it is supported by those who like to fish for wild fish.
I whole-heartedly support this proposal. I fished the Mckenzie for several hours a couple days ago, and caught 3 hatchery fish, all 9" or under. These fish (which I released) will not live to grow larger, most hatchery fish do not live more than 2-3 weeks in the wild (hence the frequent plantings). Prior to planting, before 1920, 3-4 and up to 6 pound Redside trout were common, and could be again. The Redside is adapted to live in the Mckenzie, planted fish are not.
This is not rocket science - we need only look to our neighbor Montana to find proven examples of management that works; for the fish, those who fish, and those who benefit directly and indirectly from the tourism dollars that a quality fishery brings.
There are only straw arguments against this idea. Some are rooted in a nostalgia for a time when we blissfully harvested our lands bounty without regard for consequences, some in a misplaced (or rhetorical) argument that somehow our children will miss some essential rite of passage if they are not allowed to kill planted trout in the Mckenzie. There are other, more kid friendly venues. Better, I think, that we teach our children responsible stewardship of our natural treasures.
For those who would insist on hatchery trout I have a simple solution - just hand them out, skip the part about putting them in the river where they harm our fishing, our local economy, and our wild fish.
