US regulators to vote on largest dam demolition in history

PORTLAND, Ore. (AP) — The largest dam demolition and river restoration plan in the world could be close to reality Thursday as U.S. regulators vote on a plan to remove four aging hydro-electric structures, reopening hundreds of miles of California river habitat to imperiled salmon.

The vote by the Federal Energy Regulatory Commission on the lower Klamath River dams is the last major regulatory hurdle and the biggest milestone facing a $500 million demolition proposal championed by Native American tribes and environmentalists for years.

Approval of the application to surrender the dams' operating license is the bedrock of the most ambitious salmon restoration plan in history, and if approved the parties overseeing the project will accept license transfer and could begin dam removal as early as this summer. More than 300 miles (482.80 kilometers) of salmon habitat in the Klamath River and its tributaries would benefit, said Amy Souers Kober, spokeswoman for American Rivers, which monitors dam removals and advocates for river restoration.

“This is an incredibly important milestone,” she said. “This project really carries important lessons for rivers and the conservation movement, and the most important lesson is the leadership of the tribes. It’s because of the tribes that these dams will come out and the river be will restored.”

The vote comes at a critical moment when human-caused climate change is hammering the Western United States with prolonged drought, said Tom Kiernan, president of American Rivers. He said allowing California's second-largest river to flow naturally, and its flood plains and wetlands to function normally, would mitigate those impacts.

“The best way of managing increasing floods and droughts is to allow the river system to be healthy and do its...
