Do you fish in the Columbia Slough?Graphic is a simplified map of the Columbia Slough

Eating fish is good for you and is an excellent source of protein. However, fish in the Columbia Slough may contain contaminants such as polychlorinated biphenyls (PCBs) and pesticides that are harmful to eat. Contaminated fish do not look or act sick.

Limit what you eat

Graphic says Eat only 2 fillets per monthIn 2019, the Oregon Health Authority (OHA) updated its fish advisory for resident fish from the Columbia Slough (from Kelley Point Park to Blue and Fairview lakes). Resident fish are those that live their whole lives in the slough and are exposed to contaminants in the sediments throughout their lifetime. As a result, they have higher amounts of contaminants in them.

For nearly all resident fish, OHA recommends eating ONLY ONE fillet meal each month for all fish caught in the slough. See here for exception.
