The deconstruction of Copco No. 2, the smallest of the four hydroelectric dams being removed from the Klamath River, is underway. This week, crews removed the gates, walkway, and two of the five bays down to the spillway. This work was done to direct waters around the dam, rather than over it, allowing construction crews to do work through the summer months.
“While this is just the first step, it certainly is an exciting moment,” said Mark Bransom, CEO of the Klamath River Renewal Corporation (KRRC). “Crews are making fast progress in these early stages of the project, and we are on track with our removal timeline.”
Crews placed around 10 feet of rock on either side of the dam in order to reach the gates and bays for deconstruction. Much of the Copco No. 2 infrastructure remains in place below this rock surface. Deconstruction of this dam will continue through the summer, with final decommissioning and complete removal occurring sometime in September.
“We are pleased that we were able to make so much progress this week,” noted Dan Petersen, Kiewit’s Project Manager overseeing the removal of Copco No. 2 “But removing Copco No. 2 is still not a done deal. We expect to officially wrap up this phase of the dam removal project sometime in September.”
The other three dams, Iron Gate, Copco No. 1, and JC Boyle are expected to be removed next year, beginning with the drawdown of the reservoirs in January of 2024. Their incremental deconstruction will continue throughout the year, with construction activities expected to conclude sometime in late 2024.
The Klamath River Renewal Corporation (KRRC) is a private, independent nonprofit 501(c)(3) organization formed in 2016 by 23 signatories of the amended Klamath Hydroelectric Settlement Agreement, or KHSA. KRRC is part of a cooperative effort to re-establish the natural vitality of the Klamath River so that it can support all communities in the Klamath Basin. Signatories, which include the States of California and Oregon, local governments, Tribal nations, dam owner PacifiCorp, irrigators, and several conservation and fishing groups, appointed KRRC to take ownership and oversee removal of four hydroelectric dams on the river.

Robert Lusardi is the California Trout/UC Davis Wild and Coldwater Fish Researcher focused on establishing the basis for long-term science specific to California Trout’s wild and coldwater fish initiatives. His work bridges the widening gap between academic science and applied conservation policy, ensuring that rapidly developing science informs conservation projects throughout California. Dr. Lusardi resides at the UC Davis Center for Watershed Sciences and works closely with Dr. Peter Moyle on numerous projects to help inform California Trout conservation policy. His recent research interests include Coho salmon on the Shasta River, the ecology of volcanic spring-fed rivers, inland trout conservation and management, and policy implications of trap and haul programs for anadromous fishes in California.
Patrick Samuel is the Conservation Program Coordinator for California Trout, a position he has held for almost two years, where he coordinates special research projects for California Trout, including the State of the Salmonids report. Prior to joining CalTrout, he worked with the Fisheries Leadership & Sustainability Forum, a non-profit that supports the eight federal regional fishery management councils around the country. Patrick got his start in fisheries as an undergraduate intern with NOAA Fisheries Protected Resources Division in Sacramento, and in his first field job as a crew member of the California Department of Fish & Wildlife’s Wild and Heritage Trout Program.

Hallelujah!!!
Cal Fish and Game fought unsuccessfully to block Iron Gate back in I believe the 1930’s I read the files as a young newly hired Fish and Game lawyer in 1988. It may take a hundred years to return the river to a viable salmon stream but the project is finally underway… Thanks for the coverage!!! s/ Hal Thomas Retired DFG Attorney
