July 25, 2024 — For the first time since 1918, an astonishing 420 miles of salmon habitat in the Klamath River watershed in California and Oregon will be fully connected by September. This results from the world’s largest dam removal effort, the Klamath River Renewal Project. The amount of habitat opened up on the Klamath is equivalent to the distance between Portland, Maine, and Philadelphia-a journey through seven states.
PacifiCorp, the previous owner, agreed to remove the aging dams after they determined removal would be less expensive than upgrading to current environmental standards. The dams had been used for power generation, not water storage. The Copco No. 2 Dam on the Klamath was removed last year. The deconstruction of the Iron Gate, Copco No. 1, and JC Boyle dams is underway and running ahead of schedule.
“I think in September, we may have some Chinook salmon and steelhead moseying upstream and checking things out for the first time in over 60 years,” says Bob Pagliuco, NOAA marine habitat resource specialist. “Based on what I’ve seen and what I know these fish can do, I think they will start occupying these habitats immediately. There won’t be any great numbers at first, but within several generations-10 to 15 years-new populations will be established.”
There’s more good news for Klamath salmon and steelhead. NOAA’s Office of Habitat Conservation recommends an $18 million award to the Yurok Tribe to restore and reconnect cold-water tributaries that will open to migratory fish after dam removal. Another roughly $1.9 million award is recommended to the Oregon Department of Fish and Wildlife to begin evaluating options for improving fish passage at Keno Dam. The Keno Dam sits upstream of the dams currently being removed. Nearly 350 miles of additional salmon habitat lie upstream. Both awards are funded through the Bipartisan Infrastructure Law and Inflation Reduction Act.
“The Yurok people are extremely happy to be witnessing the beginning of the Klamath River’s rebirth,” says Yurok Tribe Fisheries Department Director Barry McCovey. “The dams caused a tremendous amount of damage to the Klamath over the last century. Through the decommissioning project and holistic restoration, we are confident that we will see the Klamath’s salmon, steelhead, and Pacific lamprey runs recover.”
