Lake Mendota County Park Beach open

Public Health Madison & Dane County tested bacteria levels and checked for algae blooms on 7/8/2024. The results were acceptable. The shallow near-shore temperature was (temp) 74°F. Even though the results were acceptable at the time of monitoring, algae levels can change quickly depending on waves and wind. Always take a look at water conditions before you enter the water and avoid contact with algae blooms.
