Its been ten years since I worked at the cowlitz hatchery but my recolection is the smolts only spend a week or two in the system before they were found at the lower columbia...and feeding was very minimal. If my memory is correct(can be a big if ) this is somthing pretty basic and this bunch is reaching pretty deep. I wonder if their motivation may be to get an injuction while they drag out a lawsuit they know they have little or no chance of winning. I mean their claim sounds logical but I was just a schmuck at the hatchery and if I know this it should be pretty common knowledge to the bioligists... I guess I agree with obsessed...
