Klamath River Rebounds with Salmon Surge, Algae Decline After Dam Removal
18 Oct
Summary
- Salmon numbers surge, reaching 7,700 fish in 3 months after dam removal
- Water quality improves, with 100% of samples below public health limits for toxic algae
- Tribes celebrate river's revival, with fish returning to historic spawning grounds

As of October 18, 2025, the Klamath River in California is experiencing a remarkable ecological revival, just one year after the completion of the world's largest dam removal project. According to scientists, the river's health has begun to bounce back, with salmon swimming upstream in greater numbers than expected, and increased activity from bald eagles, bears, beavers, otters, and ospreys.
The data is staggering - in the three months following the removal of the final dam in October 2024, a remarkable 7,700 fish, primarily Chinook salmon, passed through the former dam site, averaging 588 fish per day. Researchers have also observed the first Chinook salmon ascending the Keno Dam fish ladder and leaving the fishway at the top of Link River Dam, entering Klamath Lake.
