Klamath Dam Removal Overview Report for the Secretary of the Interior: An Assessment of Science and Technical Information

This Overview Report and numerous technical reports were developed for the Secretarial Determination by scientists and engineers from Federal agencies working within the Department of the Interior (DOI), the Department of Commerce (DOC), the U.S. Department of Agriculture (USDA), and the U.S. Environmental Protection Agency (USEPA). These agencies worked collaboratively with state agencies from California and Oregon through nine sub-teams of the Technical Management Team (TMT) covering broad topical areas of the Secretarial Determination process. The TMT developed and carried out scientific, engineering, and other technical studies to fill information gaps and address the four questions which inform the Klamath Secretarial Determination identified in the KHSA. These questions are: (1) Would dam removal and KBRA implementation advance salmonid fisheries and other fisheries in the Klamath Basin; (2) What would dam removal entail, what mitigation measures may be needed, and what would these actions cost; (3) What are the major potential risks and uncertainties associated with dam removal; and (4) Would dam removal and implementation of the KBRA be in the public interest?
