Advisory based on mercury and PCBs.
Lake Merced is comprised of two adjacent, discrete waterbodies (referred to as “North Lake” and “South Lake”). Because fish evaluated for this advisory were collected only from the north lake, this advisory applies only to North Lake.
Because of the possibility that catfish in the south lake have similarly elevated PCB concentrations as in North Lake, OEHHA recommends against consuming catfish from either lake. For other species in the south lake as well as species not evaluated from North Lake, please follow OEHHA’s statewide advisory for lakes and reservoirs without site-specific advice.
