Potential Responses of Coho Salmon and Steelhead Downstream of Iron Gate Dam to No-Action and Dam- Removal Alternatives for the Klamath Basin

The intent of this report is to summarize the anticipated effects of fulfilling the terms of both the Klamath Hydropower Settlement Agreement as well as the Klamath Basin Restoration Agreement (i.e., dam removal paired with KBRA actions) on two species of anadromous salmonids: coho salmon (Oncorhynchus kisutch) and steelhead (O. mykiss), as compared with a “no action” alternative. This report will be made available to selected panels of fisheries experts to aid in the Secretarial Determination process. The analysis only addresses potential fish population responses within the Klamath mainstem and tributaries downstream of Iron Gate Dam.
