[“The return of the salmon comes less than two months after the end of the dam removals in California and Oregon, an effort that took decades of advocacy by the surrounding tribes—including the Yurok, Karuk, Shasta, Klamath and Hoopa Valley, among others—whose people have deep ties to the Chinook salmon.

Ron Reed, a Karuk tribe member and traditional fisherman, participated in the campaigns for dam removal, advocating that the river’s restoration would help salmon recover. He isn’t surprised the fish have returned so quickly to their ancestral waters, he tells the Los Angeles Times’ Ian James.

“The fact that the fish are going up above the dams now, to the most prolific spawning and rearing habitat in North America, it definitely shines a very bright light on the future,” Reed tells the Los Angeles Times. “Because with those dams in place, we were looking at extinction. We were looking at dead fish.”

In one poignant case, tens of thousands of Chinook salmon died off in the span of days in 2002, as the water quality in the dammed Klamath River deteriorated from the lack of flow. The dams, built between the early 1900s and 1962, also contributed to algae blooms and diseases, and they blocked the salmon’s annual migration.

The mass salmon deaths helped spark decades of advocacy from Klamath tribes and conservation groups. In November 2022, the Federal Energy Regulatory Commission approved the $500 million project. The first dam to be destroyed, Copco No. 2, came down in fall 2023. Beginning in January this year, the remaining three dams had their reservoirs drained and their infrastructure removed. For the first time in more than a century, the river flowed freely by the end of August.
