Executive Summary The Secretary of the Department of the Interior is required to decide if implementation of the Klamath Hydropower Settlement Agreement (KHSA) and Klamath Basin Restoration
Agreement (KBRA) (1) will advance restoration of the salmonid fisheries of the Klamath Basin; and 2) is in the public interest. Two alternative management scenarios before the Secretary of
the Interior must be addressed in the Secretarial Determination: (1) Conditions with dams, also referred to herein as the “Current Conditions”; and, (2) Conditions without dams and with the KBRA, also referred to herein as the “Proposed Action.” This expert panel (Panel) was convened to attempt to answer a provided list of specific questions that had been formulated to distinguish between the effects of the two alternatives (Current Conditions and the Proposed Action) on coho salmon (Oncorhynchus kisutch) and steelhead (Oncorhynchus mykiss). Coho salmon in the Klamath River Basin are included in the Southern Oregon/Northern California
Coast Evolutionary Significant Unit (SONCC ESU) and were federally listed as threatened under the Endangered Species Act on May 6, 1997 (62 FR 24588). Report summarizes process of the expert panel, findings, and notations of any limitations based on data gaps and other factors.
