Advisory based on mercury or PCBs
This is an update of the report issued in December 2012 for Lake Oroville. In 2013, the California Department of Fish and Wildlife changed the legal size for black bass to 12 inches or longer, instead of the previous slot limit of 12 to 15 inches. As a result, some bass that were legal to keep and consume in 2012 are now not legal to keep. The advisory and the report have been updated to reflect that only legal-sized fish have been used in the evaluation.
