KLAMATH RIVER, Calif. -- Work has wrapped up on the world's largest dam removal project. The Klamath River Renewal Corporation announced today that the four hydroelectric dams in the Klamath River have been completely removed.

Indigenous tribal nations along the California-Oregon border have campaigned for decades to tear down four hydroelectric dams they say destroyed the river’s ecosystem and upended their way of life.

The largest dam removal project in U.S. history was completed Wednesday, marking a major victory for tribes in the region who fought for decades to free hundreds of miles of the Klamath River near the California- Oregon border.
