Swimming in Dane County Lakes
One of the great assets of the Madison and Dane County area is the many beaches located throughout Dane County. Public Health Madison & Dane County monitors all public beaches during the swimming season, Memorial Day through Labor Day, to assure safe water quality and minimize public health risks from water-borne pathogens and toxins.
In order to keep yourself healthy while swimming, observe the warning or closing signs concerning possible contamination. Occasionally, particularly after heavy rain or flooding, illness causing microorganisms, such as bacteria, viruses, protozoa and blue-green algae may be present in the water.
