News Summary
A crucial $4.3 million grant from NOAA Fisheries has been awarded for the Sunol Valley Fish Passage Project, aimed at enhancing aquatic life in the Alameda Creek watershed. This project involves lowering a gas pipeline to remove barriers preventing native fish species, such as Chinook salmon and steelhead trout, from accessing upstream habitats. Scheduled for construction commencement in June 2025, this initiative marks the completion of the 16th fish passage project in the region, reflecting ongoing efforts to protect and revitalize the local ecosystem.
Funding Secured for Final Fish Passage Barrier Removal Project in Alameda Creek
A significant milestone has been achieved in the preservation of aquatic life with the recent announcement of a grant of $4.3 million for the Sunol Valley Fish Passage Project. This funding, awarded by NOAA Fisheries, a federal agency dedicated to the conservation of natural resources, is aimed at enhancing fish passage in the Alameda Creek watershed.
As part of this initiative, preparations are underway to lower a PG&E gas pipeline that currently stretches over Alameda Creek approximately 12 miles upstream from where the creek meets the bay. This undertaking marks the completion of the 16th fish passage project in the region over a span of 20 years.
The necessity for such projects arises from urban development in the lower 12 miles of Alameda Creek, which has created barriers that impede the movement of native aquatic species, specifically Chinook salmon and steelhead trout. These species have struggled to access upstream waters for spawning due to the challenges posed by urbanization.
History of Fish Passage Projects
Historically, previous efforts to improve fish passage have included the installation of fish ladders at the Fremont BART station weir and the establishment of inflatable bladder dams near Niles, managed by the Alameda County Water District (ACWD). The current project has been in development since approximately 2012, with significant progress made when California Trout (CalTrout) assumed leadership in July 2023, at which point the project was about 65% designed.
In its new role, CalTrout is managing collaboration among project partners and guiding the process of obtaining necessary permits. Anticipated construction will begin in June 2025 and continue through October of the same year.
Challenges and Proposed Solutions
The existing PG&E pipeline, which was constructed in 1963, currently poses a barrier for both salmon and lamprey due to its elevation and the presence of an erosion control apron. These structural elements complicate the fish’s ability to navigate through to more favorable upstream habitats. The revised plan proposes to sink the pipeline between 17 and 20 feet below creek level and to remove the erosion control apron entirely.
Funding for the pipeline relocation will largely come from PG&E, while the $4.3 million grant will cover costs related to revegetation and site regrading following the completion of construction work.
Ecological Importance of the Project
This restoration effort is seen as critical, as salmon and steelhead serve as key indicators of ecosystem health. Historically, the Alameda Creek watershed has supported substantial populations of these fish; however, current numbers are declining and face threats from both urban development and pollution.
The significance of restoring fish passage extends beyond the aquatic species; it plays a vital role in the overall ecological integrity of the region, affecting water quality and stream conditions. The restoration contributes to a larger initiative valued at $80 million, aimed at revitalizing the entire Alameda Creek watershed as managed by the ACWD.
As a crucial water supply source for millions residing in the Bay Area, ensuring the health of the Alameda Creek ecosystem is of paramount importance. The removal of fish passage barriers stands as a vital step toward preserving this vital waterway for future generations.
