The Klamath River once supported the third-largest salmon run on the West Coast. Today, salmon and steelhead runs are a fraction of their historic abundance, with some near extinction. As a result, all Klamath Basin communities are suffering in some way, including Tribes, farmers, commercial fishermen and others. Learn more (PDF)
American Rivers has played a lead role in the effort to restore the Klamath River since 2000. Represented by AR staff and outside counsel Richard Roos-Collins of the Natural Heritage Institute we played an instrumental role in achieving the historic success of developing two settlement agreements, signed in Salem Oregon in February 2010, that create a path to the largest dam removal ever undertaken and the restoration of the Klamath River and several key tributaries. The agreements also settle many of the longstanding water allocation and other disputes in the Klamath Basin. The agreements will help restore the river and revive its ailing salmon and steelhead runs and aid fishing, tribal and farming communities. It will also help end decades-long disputes over river management in the basin.

What will a free-flowing Klamath River look like?
Using special computer modeling software, American Rivers has created 3-D photo-realistic visualizations that depict the Klamath River before, during, and after dam removal. We have extracted a series of movies and animations from the model landscape to help illustrate how the reservoirs will drain, how vegetation will return, and the Klamath River ecosystem will be restored.
