Sacramento River and Northern Delta

Advisory based on mercury, PBDEs, or PCBs.

This advisory is for the Sacramento River from just below Shasta Lake to where it joins the San Joaquin River in Pittsburg, and for creeks, sloughs, and other water bodies in the Delta north of Highway 12. The Sacramento River and Northern Delta posters and supporting documents were revised in November 2022 to include the updated advice for American Shad, Chinook (King) Salmon, Steelhead Trout, Striped Bass, and White Sturgeon, based on the Advisory for Fish that Migrate.

NOTE: Crayfish advice was removed while OEHHA evaluates other contaminants in this species that may affect advice.
