You’ll have to wait before you take a dip at Nicolet Beach in Peninsula State Park. Lab results showing increased levels of E. coli bacteria on water near shore has caused the closure by the Wisconsin Department of Natural Resources on Wednesday. As levels above recreational water quality standards require either a swim advisory or a beach closure, you are encouraged to check the DNR’s website for updates on a beach’s status. Because bacteria levels can fluctuate over the 18-24 hour time period it takes for lab analyses to be done, the results in the online database may not reflect current levels.
