DEAL REVIVES PLAN FOR BIGGEST U.S. DAM DEMOLITION

An agreement announced paves the way for the largest dam demolition in US history, a project that promises to reopen hundreds of miles of waterway along the Oregon-California border to salmon that are critical to tribes but have dwindled to almost nothing in recent years, Gillian Flaccus reported for the Associated Press (AP).

If approved, the deal would revive plans to remove four massive hydroelectric dams on the lower Klamath River, creating the foundation for the most ambitious salmon restoration effort in history. The project on California’s second-largest river would be at the vanguard of a trend toward dam demolitions in the US as the structures age and become less economically viable amid growing environmental concerns about the health of native fish. Removed would be the four southernmost dams in a string of six constructed in southern Oregon and far Northern California beginning in 1918. They were built solely for power generation. They are not used for irrigation and not managed for flood control. The lowest dam on the river, the Iron Gate, has no “fish ladder,” or concrete chutes that fish can pass through. More than 1,720 dams have been dismantled around the US since 2012, according to American Rivers, and 26 states undertook dam removal projects in 2019 alone. The Klamath River project would be the largest such project by far if it proceeds.


The dams blocked blocked hundreds of miles of potential fish habitat and spawning grounds, and fish populations have dropped precipitously in recent years. Salmon are at the heart of the culture, beliefs and diet of a half-dozen regional tribes, including the Yurok and Karuk — both parties to the agreement — and they have suffered deeply from that loss. Coho salmon from the Klamath River are listed as threatened under federal and California law, and their population in the river has fallen anywhere from 52% to 95%. Spring chinook salmon, once the Klamath Basin’s largest run, has dwindled by 98%. Fall chinook, the last to persist in any significant numbers, have been so meager in the past few years that the Yurok canceled fishing for the first time in the tribe’s memory. In 2017, they bought fish at a grocery store for their annual salmon festival.


The new plan makes Oregon and California equal partners in the demolition with the nonprofit entity called the Klamath River Renewal Corp. It adds another $45 million to the project’s $450 million budget to ease those concerns. Oregon, California and the utility PacifiCorp, which operates the hydroelectric dams and is owned by billionaire Warren Buffett’s company Berkshire Hathaway, will each provide one-third of the additional funds. The Federal Energy Regulatory Commission must approve the deal. If accepted, it would allow PacifiCorp and Berkshire Hathaway to walk away from aging dams that are more of an albatross than a profit-generator, while addressing regulators’ concerns. Oregon, California and the nonprofit would jointly take over the hydroelectric license from PacifiCorp while the nonprofit will oversee the work. Buffett said the reworked deal solves a “very complex challenge.” He added: “I recognize the importance of Klamath dam removal and river restoration for tribal people in the Klamath Basin. We appreciate and respect our tribal partners for their collaboration in forging an agreement that delivers an exceptional outcome for the river, as well as future generations.”
