Largest Dam Removal In US History Is Complete

The largest dam removal project in U.S. history has been completed with the demolition of four dams on the Klamath River, marking a significant victory for tribal nations on the Oregon-California border who have long fought to restore the river to its natural state. However, as CNN's Rachel Ramirez and the BBC's Lucy Sherriff both highlight, the restoration of salmon populations and surrounding ecosystems is 'only just beginning.' From the report: The removal of the four hydroelectric dams -- Iron Gate Dam, Copco Dams 1 and 2, and JC Boyle Dam -- allows the region's iconic salmon population to swim freely along the Klamath River and its tributaries, which the species have not been able to do for over a century since the dams were built. Mark Bransom, chief executive officer of the Klamath River Renewal Corporation, the nonprofit group created to oversee the project, said it was a 'celebratory moment,' as his staff members, conservationists, government officials and tribal members gathered and cheered on the bank of the river near where the largest of the dams, Iron Gate, once stood. The Yurok Tribe in Northern California are known as the 'salmon people.' To them, the salmon are sacred species that are central to their culture, diet and ceremonies. As the story goes, the spirit that created the salmon also created humans and without the fish, they would cease to exist. Amy Bowers-Cordalis, a member of and general counsel for the Yurok Tribe, said seeing those dams come down meant 'freedom' and the start of the river's 'healing process.'

The utility company PacifiCorps -- a subsidiary of Warren Buffet's Berkshire Hathaway Energy -- built the dams in the early to mid-1900s, without tribal consent, to generate electricity for parts of the growing West. But the dams severely disrupted the lifecycle of the salmon, blocking the fish from accessing their historic spawning grounds. Then there's the climate crisis: Warm water and drought-fueled water shortages in the Klamath River killed salmon eggs and young fish due to low oxygen and lack of food and allowed the spread of viruses. As for the reason the dams were constructed in the first place -- electricity -- removing them won't hurt the power supply much, experts say. Even at full capacity, all four dams produced less than 2% of PacifiCorp's energy, according to the Klamath River Renewal Corporation. Up next is ramping up restoration work. Bransom said they plan to put down nearly 16 billion seeds of almost 100 native species across 2,200-acres of land in the Klamath River Basin. And after more than a century, the fish can now swim freely. Yurok's Bowers-Cordalis said seeing the river reconnected is a form of giving their land back, which is really the 'ultimate reward.'
