Klamath River Dam Removal

Four dams to come down by 2021

Long-term Goal

Recover Klamath River salmonid populations by removing 4 dams on the Klamath River (Iron Gate, Copco 1, Copco 2, and JC Boyle) and opening up fish passage to over 400 miles of potential spawning and rearing habitat.


The Klamath River, which flows through parts of Southern Oregon and Northern California, has four aging hydroelectric dams which have blocked salmon and steelhead fish from reaching more than 300 miles of potential spawning and rearing habitat. Removal of the river’s four dams – J.C. Boyle, Copco 1, Copco 2, and Iron Gate have been the subject of national attention for nearly two decades

Progress has been made towards the most significant dam removal effort in US history when the Klamath River Renewal Corporation (KRRC) filed its “Definite Plan for the Lower Klamath Project” with the Federal Regulatory Energy Commission (FERC).

The Definite Plan is a 2,300-page document that provides a comprehensive analysis and detail on project design, deconstruction, reservoir restoration, and other post-deconstruction activities. Additional topics covered include plans to: manage construction impacts, manage impacts to groundwater wells, perform flood-proofing, improve roads and bridges, provide recreation opportunities, replace the City of Yreka water line, protect aquatic resources, and provide for ongoing fish hatchery operations.

Dam removal is projected to improve water quality and revive flagging salmon and steelhead fisheries on this major river system. Removal additionally provides economic benefit to the region by creating local jobs and boosting tourism and recreation in the area. A study released by the US Geological Survey in 2017 demonstrated fish are eager to return to the upper reaches of watersheds after dam removal, even if the areas have been blocked for decades or more. The study showed that historic upstream habitat can be recolonized by fish in a matter of weeks after access is restored.

Restoration activities outlined in the Definite Plan will include improving habitat along the river. CalTrout has been active in the region and has, among other projects, partnered with ranchers along the Scott and Shasta Rivers – two Klamath River tributaries – to improve conditions for migratory fish that are likely to return to the system once the dams are removed.

CalTrout has been and continues to be deeply involved in the effort to identify a way forward in the Klamath Basin that respects the needs, rights and values of residents, Tribes, ranchers and farmers, and conservationists who are all invested in the future of this region.
