New PFAS fish consumption advisories for lakes and rivers in Dane, Rock counties

MADISON, Wis. — New PFAS fish consumption advisories for the Yahara Chain waters in Dane and Rock counties were issued Wednesday.

According to a news release from Wisconsin DNR, the advisories were based on results from fish sampling conducted in 2020.

The release said elevated levels of PFOS, a type of PFAS, were found in several fish species collected from lakes Monona, Kegonsa and Waubesa.

As a result, officials said the DNR and DHS have developed new advisories for the Yahara Chain waters from Wingra Creek, Starkweather Creek, Lake Monona, Lake Waubesa, Upper and Lower Mud Lakes, Lake Kegonsa and the Yahara River downstream to where it meets the Rock River.

Officials said the risk of health problems increases with the amount of contaminated fish a person eats.

The DNR and DHS recommend the consumption of one meal per month for crappie, largemouth bass, northern pike and walley; and one meal per week of bluegill, pumpkinseed and yellow perch.

A complete list of consumption advisories can be found on the DNR’s website.
