In 2025, California buried a gas pipeline 20 feet below Alameda Creek and removed its final 8-foot barrier; that same week, Chinook salmon reached this part of the watershed for the first time since the 1950s
- Representative Image (AI-generated)A barrier that had blocked migratory fish for decades disappeared in California in 2025, and salmon soon followed the newly opened route.
- Crews relocated a Pacific Gas & Electric (PG&E) natural-gas pipeline and buried the new section about 20 feet below Alameda Creek near Sunol, then removed the concrete structure that had created an 8-foot drop in the creek.
- The work reopened more than 20 miles of upstream habitat, and that same week, biologists spotted two Chinook salmon beyond the former barrier, marking the first documented access to this part of the wate
