Sometimes we
I agree in principle but we disagree in approach. I would be happy with starting...somewhere...Its not accurate in my view to say salmon behind these dams are gone. Salmon are very resilient and given their high fecundity and migratory capabilities - they could recolonize any habitat opened up. Steelhead maintain a resident life history and as soon as they had passage would resume an anadromous life cycle, so they would re-establish even more rapidly.
However, if we ignore the dams which have by far a greater impact on salmon and steelhead numbers in Idaho and only focus on dams downstream of Idaho's border (a preferred strategy for some of Idaho's politicians - and I don't mean this as a jab at you or others) - then any of the lower Columbia Dams have a substantially greater impact on Idaho's salmon than the lower Snake dams. Much higher predator concentrations on juvenile fish (avian and fish) and then add in sea lions feasting at Bonneville Dam...its difficult to provide quantitative estimates of the potential impact difference, but the bonus of targeting lower Columbia dams...you are now tackling dams that all 13 ESA listed stocks of salmon in the Columbia must navigate as opposed to the subset of 4 stocks that pass the Snake River dams.
The last part of your statement is true...when comparing lower Snake and lower Columbia dams, the Columbia dams produce much more hydropower benefits.
