Breaching dams to save Northwest orcas is contentious issue

TACOMA, Wash. (AP) Calls to breach four hydroelectric dams in Washington state have grown louder in recent months as the plight of critically endangered Northwest orcas has captured global attention.
Some argue the best way to get more salmon to the starving whales is to tear down four dams on the Lower Snake River, a tributary of the Columbia River, to help migrating fish.
But federal agencies and others have pushed back, saying the dams provide benefits to the region in low-cost hydropower, navigation and recreation.
Breaching the dams has long been contentious, but it's gained renewed attention as the orcas have hit the lowest numbers in more than three decades. The whales struggle from pollution, boat noise and lack of chinook salmon, which have been declining because of dams, habitat loss and overfishing. Just 74 animals remain in the small group.

(12 posts)Hi Judi,
I live very close to you, five minutes away from Puget Sound. I am astounded that there are only 74 animals left. I go to the beach on a daily basis in the summer and have seen the Orca but recently have only seen Minke whales. It is very sad.

(2,606 posts)be correct. Otherwise I'm not seeing how restoring habitat would not result in increased salmon.
Unless I'm wildly incorrect, I believe there were more salmon before the dams were built. The issue is that I doubt that the population would rebuild in time to help this resident pod of orcas.
While orcas range world wide, resident pods have not interbred with transient pods in over 100,000 years. They have their own distinct "language" and "culture". Resident pods only eat fish, while transients will attack other whales and other large marine mammals.
Preservation of the resident pods should be given a high priority. How would you approach preservation?

(23 posts)I don't understand. The damns that have been breached on the Olympic peninsula have already led to a return of salmon. Where do you get your information from? Your conjecture makes no sense.
Can the power from the damns be replaced with solar / tidal / wind power?
Please supply links, unless of course if you are a troll.
