California and Oregon- The Iron Gate, Copco No. 1, Copco No. 2 and J.C. Boyle dams, located on the Klamath River at the California and Oregon border, were built between 1903 and 1962 to provide hydroelectric power. Now they are being demolished at an estimated cost of $398 million. The Federal Energy Regulatory Commission (FERC) is reviewing Transfer and Surrender applications submitted by the Klamath River Renewal Corp. (KRRC). KRRC plans to take ownership of the dams from its current owner – PacifiCorp – then remove them, restore formerly inundated lands and implement required mitigation measures in compliance with all applicable regulations. The corporation has performed site assessments and engineering studies leading to the development of the Definite Plan for the Lower Klamath Project, filed with FERC on June 28, 2018. The 2,300-page plan provides comprehensive analysis and detail on project design, dam removal, reservoir restoration and other post-deconstruction activities.
The KRRC is securing the engineering and construction resources needed for dam removal and site restoration. KRRC will soon issue a request for qualifications (RFQ) for the dam removal design-build contract, followed by a request for proposals at the end of the year. The selected firm will operate under a progressive design-build delivery method. Pending regulatory approval, this massive project will take place in phases, beginning with site preparation in mid-2020 and deconstruction expected to begin in 2021.
