Toxic Blue-Green Algae Update: June 30, 2022 Toxic Blue-Green Algae Update: This algal bloom was first reported by persons in View Crest subdivision last Thursday, June 23. The Town of Delavan and the Delavan Lake Sanitary District responded immediately. Health Alert signage was posted at the Delavan Community Park, and other public launch and several private boat launches. We have since been in continuous contact with the WDNR, the state Dept. of Public Health, and the Walworth County Dept. of Health. Experts in the field of Harmful Algal Blooms have confirmed the presence of the Blue-Green algae. To date, there have not been any reports of illness related to this Health Alert, and the Town of Delavan will continue to monitor the situation closely and follow all guidance and directives that have been provided by the appropriate departments locally and at the state level. Due to the weather projections going forward into next week, it is expected that the conditions that supported this algal bloom last week may continue to be in place at least into next week; therefore, the Health Alert postings and the beach closure at the Community Park will remain in effect. Please continue to go to the Town of Delavan website for any updates. https://www.dhs.wisconsin.gov/publications/p01888.pdf
