Some awfully good arguments both for and against dams. And I agree with both. I think Todd gets my vote, however, for his statement that there is no excuse for dams without fish passage. I live close to the Elwha River, which is a supreme example of lack of forethought when it came to putting in dams. You probably all are familiar with its story....if not, a quick search will tell it all. A HUGE king salmon species now extinct. Like Todd said.....no excuse.
