“The Klamath River project will be the most significant dam removal and river restoration effort yet. Never before have four dams of this size been removed at once which inundate as many miles of habitat (4 square miles and 15 miles of river length), involving this magnitude of budget (approximately $397 million) and infrastructure.

But perhaps more important than the size of the dams is the amount of collaboration and the decades of hard work that have made this project possible. American Rivers has been fighting to remove the dams since 2000. And thanks to the combined efforts of the Karuk and Yurok tribes, irrigators, commercial fishing interests, conservationists, and many others, our goal of a free-flowing river is now within reach.”

Biggest dam removal ever! Klamath was largest salmon producer until dams interrupted reproduction cycles.
