CHILOQUIN, Ore. - The Klamath Tribes today filed a lawsuit against the Bureau of Reclamation in federal district court in Medford, Oregon, over Reclamation’s ongoing violations of the Endangered Species Act in its operation of the Klamath Project. C’waam (Lost River sucker) and Koptu (shortnose sucker), two critically endangered fish of vital spiritual and cultural importance to the Tribes, are being pushed to the very brink of extinction by Reclamation’s violation of one of our country’s bedrock environmental laws.
