The Office of Environmental Health and Hazard Assessment (OEHHA) has developed a Statewide Advisory for eating fish from California’s Lakes and Reservoirs. The advisory is based largely on the methylmercury content of the tissue of certain types of fish. Even though mercury and methylmercury are well below measurable levels in the water, over time trace amounts from atmospheric deposition and runoff bioaccumulate in fish. The Advisory provides guidance on consumption of fish taken from California’s lakes and reservoirs. Below is a Pictorial Advisory issued by OEHHA:

The California State Water Resources Control Board is developing a Statewide Mercury Control Program for addressing mercury in California’s lakes and reservoirs. Additional information on the State’s Program and data from the State’s water bodies can be found on the California Waterboards Website and the California Environmental Data Exchange Network.
