Not winning any environmental plaudits, GOP presidential hopeful George W. Bush yesterday announced his opposition to breaching four dams on the Snake River to help save endangered salmon runs. As he kicked off a campaign swing through the Northwest, Bush said, “I think it’s very important for us to protect the fish, but I think we can do so in a way that doesn’t cause the dams to have to be breached. I understand how significant the dams are.” The Army Corps of Engineers is expected to complete a study next year on whether breaching is the best way to help the salmon.
