Not using hatchery supplementation might have a chance if all the marine mixed stock fisheries would be closed so that the Elwha and other streams with dams removed could recover. But, we will keep killing those fish in the ocean. Take away the hatchery fish and more of the wilds will be taken in the ocean. It's simple math.

When I was involved in the Elwha recovery I tried to suggest that a myriad of methods be tried. Maybe the traditional methods with Chinook as we already had an ongoing program. Leave steelhead, sockeye, and pinks alone and see what natural recovery does. Flood the system with fry/eggs taken from all sorts of neighboring socks of coho (3 years) and chum (4 years) to put in a tone of genes and the let God sort them out. I got moved to another position too after.
