According to an update from the City of Janesville, the Lions Beach most recent water quality test showed elevated bacteria levels (613 ppm/100 mL) of E. coli in the swimming area. These results require the Recreation Division to post a water quality advisory notice. They do not, however, direct the beach to be closed.
Water quality standards state that any test result between 0-250 ppm is safe for swimming. Test results between 250-1,000 ppm are safe for swimming but require public notice. Any test result greater than 1,000 ppm mandates the swimming area to be closed pending further testing.
The Recreation Division will remove water quality advisory signs when the one-day result of sampling following the excess is below the established criteria. If you have questions, call the Recreation Division at (608) 755-3030.
