The removal of two dams blocking Northern California’s Eel River is one step closer to happening. On November 17, Pacific Gas and Electric Company (PG&E), the owner of the dams, released its initial draft plan for dismantling the Scott and Cape Horn dams and relinquishing its license for the 113-year-old Potter Valley Hydroelectric Project.
Crews spent October putting the final touches on the removal of the Copco No. 2 Dam on California’s Klamath River, removing the remaining diversion infrastructure, grading the river channel, and performing erosion control. Deconstruction of the dam structure was completed in September. This work prepares the river canyon for consistent river flows, something which the river canyon below the dam hasn’t seen in 98 years. Restored flows in this reach will provide new whitewater boating opportunities on a section of river that has been dewatered and inaccessible to the public. Only a handful of boaters have ever been able to experience this run.
One of the primary concerns when planning for dam removal is the impact of sediment transport on water quality, river health, and the communities that depend on healthy rivers.
