OEHHA has finalized a fish advisory concerning elevated levels of mercury in fish in Clear Lake, Cache Creek and Bear Creek (Lake, Yolo and Colusa counties). This region has an abundance of naturally occurring mercury as a result of both natural processes and mining activity and some of the mercury has worked its way into the fish.
Fish are nutritious and good for you to eat.
- Fish are an excellent source of protein and most are low in saturated fats.
- Fish contain omega-3 fatty acids that can reduce your risk for heart disease and improve how the brain develops in unborn babies and children.
- But some fish you catch may take in toxic chemicals from the water in which they live and the food they eat.
- Some of these chemicals build up in the fish - and in you - over time.
- Check our Fish Advisories for help on how to pick the best fish for you and your family.

OEHHA has finalized a fish advisory concerning elevated levels of mercury in fish in Tomales Bay in Marin County. “With the exception of sharks, fish caught in Tomales Bay can be part of a healthy, balanced diet. But the public – and particularly women of childbearing age and children – should monitor and limit their fish consumption to avoid excessive exposure to mercury,” OEHHA Director Dr. Joan Denton said.
Fish are still recommended as part of a healthy, balanced diet. But anglers and their families – especially women of childbearing age and children – should be aware of the presence of mercury in fish from Lake Natoma and the lower American River, and follow our guidelines for safe consumption.
This draft advisory updates and replaces a 1987 state fish advisory for Clear Lake, and expands the advisory to include Bear Creek and Cache Creek. The draft advisory recommends that no one should eat any fish or shellfish from Bear Creek, and limits fish consumption in other areas.
