We would like to clarify some misinformation that is being circulated. The beaches at Petenwell, Castle Rock, and Arrowhead Lakes are NOT closed related to Blue-Green Algae. The report that is being circulated in recent days is from last year. For current information always be sure to check this page as well as the Adams County Health Department Website.
