Absolutely, there is.
I'm not aware of really successful chinook salmon hatchery programs. Maybe I'm simply unaware. The Whitehorse dam was built 75 years ago. It's up for relicensing.
There's a similar dam on the Mayo River, which is an important chinook spawning river. The Mayo dam has absolutely extirpated all of the salmon that used to spawn above it, which I understand was quite a few, according to the Na-Cho Nyak Dun. There was no fish ladder built 75 years ago and no allowance for out-migrating. Of course, if the fish can't get up, they don't need to come back down.
I think there are definitely ways to improve those facilities. Hopefully, as part of the dam relicensing, that will happen. Is it going to be the panacea? I don't think so, but it can certainly help. My view of the world is that at this point we have to do everything we can to save the salmon, because they are disappearing before our eyes.
