- karaterobot 4y agoWell, certainly not the same salmon. But I'm asking about the water quality. I'm not asking about the effect of dams on salmon, or even of the effect of poor water quality on salmon (which would be obvious). I'm only asking about the mechanisms by which dams change the quality of water.
