"Since the beginning of November, volunteers from the nonprofit group Alameda Creek Alliance which has worked to remove dams and install fish ladders since 1997 have recorded nearly a dozen specimens of Chinook Salmon. These sightings come just weeks after PG&E and the nonprofit CalTrout finished a $15 million project to remove a gas pipeline that was the last barrier impeding fish migration upstream."
"Fish ladder along the Alameda Creek on Wednesday, Nov. 26, 2025, in Fremont, Calif. The fish passage was completed in 2022 and provides watershed access that had been totally obstructed by the BART weir. (Aric Crabb/Bay Area News Group) It's just the beginning of this whole migration season, so I can't wait to see what else comes up through our project site, said Claire Buchanan, Bay Area regional director of CalTrout."
Adult Chinook salmon were observed ascending the 86 vertical feet needed to reach Alameda Creek in lower Niles Canyon for the first time in 70 years. Volunteers from Alameda Creek Alliance recorded nearly a dozen Chinook sightings since early November. PG&E and CalTrout completed a $15 million removal of a gas pipeline that had blocked upstream migration. Fish passage improvements including a 2022 fish ladder and prior dam removals and installations of fish ladders have restored watershed access. Conservationists link the salmon return to recent heavy rains and anticipate more migrations during the wet season.
