Rivers & Tributaries
Currently, DEQ does not analyze rivers and tributaries. Please follow our general advice for untested bodies of water for consumption guidance.
Advice for the General Population:
Since women beyond child-bearing age and men older than 15 years of age are at less risk for the effects of mercury, these groups may continue to eat a variety of fish, including predators, as part of a healthy diet unless specifically advised otherwise.
Advice for the Sensitive Population:
Women of child-bearing age and children up to the age of 15 should consume no more than 1 meal per week of predator fish. Predator fish include largemouth, smallmouth, spotted, white, striped, or hybrid bass, walleye, saugeye, and flathead catfish.
