Beach Water Testing:

To assess and assure water quality of Fond du Lac County owned and operated swimming beaches, Wolf Lake swimming area is tested during the swimming season for E.coli levels. A Beach advisory sign is posted whenever the level of E.coli exceeds 235 cfu/100 mL. A Beach closure sign is posted whenever the level of E.coli exceeds 1000 cfu/100ml.  Beach advisory sign is removed when water samples collected on two separate days are below 235 cfu/100ml. Elevated E.coli readings increase swimmers risk of developing gastrointestinal symptoms including nausea, vomiting, and diarrhea.
