Cfm,
Now i think that you are going a little overboard. Didn't you infact say that some 55% of the fish are spilled into riffe and become land locked? Well than what is the problem with catching them? Will they spawn? Will they "jump" the dam and somehow make it to the ocean? The coho in the cowlitz are quite plentiful and even as of last year they had landlocked salmon status after December 31 i believe. I think that catching the coho smolt stocked or spawned in riffe will really have no bearing in the "lively hood" of the run! Correct?
