Seems like there were more returns to the Deep River site a few years ago. I don't know if anything is different besides the terminal return. I can't see how final rearing & release of Cowlitz stock in Willapa Bay would improve returns, even for a wipe out fishery. Well at least they wouldn't have to worry about unselective gillnets killing wild springers. That would be an upside. However the idea seems insidious to me.
