Chinook salmon were spotted swimming in Oregon's Chiloquin Basin for the first time in 100 years, following a historic dam removal and river restoration project. The return of these iconic fish represents the culmination of decades of environmental advocacy by Indigenous communities and conservationists.
In one of the most emotional ecological victories of 2025, chinook salmon were spotted swimming in Oregon's Chiloquin Basin for the first time in a century. The return of these magnificent fish to waters their ancestors once filled is the result of a historic dam removal and river restoration project that reconnected hundreds of miles of habitat.
For the Klamath Tribes, who have inhabited the region for millennia and consider the salmon a sacred part of their culture and identity, the moment was deeply moving. Tribal leaders and elders gathered along the riverbank to witness the first salmon making their way upstream — a sight that generations had been told they would never see again.
“The return of these magnificent fish to waters their ancestors once filled is the result of a historic dam removal and river restoration project that reconnected hundreds of miles of habitat.”
The dam removal project, one of the largest in US history, involved dismantling four hydroelectric dams on the Klamath River that had blocked salmon migration for over a century. The dams had devastated salmon populations, degraded water quality, and disrupted the river ecosystem that sustained both wildlife and Indigenous communities.
The effort to remove the dams took decades of advocacy, legal battles, and negotiations between tribal nations, environmental groups, farmers, and the dam's owners. The eventual agreement represented a landmark compromise, acknowledging that the ecological costs of the dams far outweighed their energy benefits.
Within months of the final dam's removal, the river began to transform. Water quality improved, native vegetation returned to formerly inundated areas, and — most dramatically — salmon began migrating to spawning grounds they hadn't reached in 100 years. Biologists set up monitoring stations and were thrilled to document healthy chinook salmon navigating the restored river channels.
"This proves that rivers can heal," said one biologist involved in the monitoring program. "When we remove the obstacles, nature responds with remarkable speed and resilience."
The Klamath dam removal serves as a powerful model for river restoration projects worldwide. With thousands of aging and obsolete dams across the globe, the success on the Klamath demonstrates that removing barriers to fish migration can rapidly restore ecosystems and reconnect communities with their natural heritage.
