California Trout (CalTrout) and Pacific Gas & Electric (PG&E) kicked off construction today on a project that will remove the last unnatural barrier to fish passage on mainstem Alameda Creek, the largest local tributary to the San Francisco Bay. … This project will open more than 20 miles of stream including quality spawning habitat in the upper watershed to Chinook salmon and steelhead with completion anticipated in winter 2025. … In 2022 and 2023, former barriers at the BART weir and inflatable bladder dams in Fremont, eight to ten miles upstream of where Alameda Creek enters the Bay, were made passable for fish due to newly constructed fish ladders by the Alameda County Water District and after years of advocacy by the Alameda Creek Alliance. The newly constructed fish ladders enabled Chinook salmon and steelhead to migrate through the lower creek into Niles Canyon and access parts of the upper Alameda Creek watershed for the first time in over fifty years. Soon, these fish will be able to consistently swim even further upstream.
