2005 Multi-party negotiations that ultimately lead to the Klamath Basin Restoration Agreement and the Klamath Hydroelectric Settlement Agreement begin in earnest.
2006 PacifiCorp’s license for Klamath Hydroelectric Project expires. The relicensing process continues; the company faces major costs to meet environmental standards required by federal regulators.
2006 Projected weak runs of Klamath River Chinook salmon force closure of the ocean salmon harvest from Monterey, California, to Southern Oregon.
2008 In January, Draft Klamath Basin Restoration Agreement released; provides for settlement of key water conflicts and calls for a major salmon restoration effort; also calls for separate agreement concerning the removal of the Klamath Hydroelectric Project dams.

2009 Draft Klamath Hydroelectric Settlement Agreement released.
2010 Final Klamath Basin Restoration Agreement and Klamath Hydroelectric Settlement Agreement signed. Implementation contingent on authorizing legislation, funding and environmental review.
2012 Final Klamath Dam removal EIS/EIR issued

To move the project forward, the states of California and Oregon, the Yurok Tribe, the Karuk Tribe, PacifiCorp and the Klamath River Renewal Corporation sign a memorandum of agreement that describes how the parties will implement the amended Klamath Hydroelectric Settlement Agreement, which sets the terms for the removal of the four Klamath River dams.
