Dams and Chinook
And, Welch says he’s never really argued against freshwater travel being the problem for Chinook, until recently: “You know, it makes sense and all of us that are conservationists, you know, hunters or fishermen, are taught that from an early age. But where the challenges come is that the big drivers are happening in the ocean not so much in fresh water. And, we may be getting some kind of distorted policy decisions because of that lack of appreciation of what’s happening in the ocean.”
The study found the survival rate is similar for salmon traveling through all West Coast rivers, with and without dams, to a common destination, the Pacific Ocean.
