Outagamie County Parks Department is closing Plamann Lake for the season to prevent the spread of COVID-19.
Park officials say unlike many public swimming pools, Plamann Lake is untreated and its capacity to contain microorganisms is uncertain.
"We don't know how the virus reacts in freshwater, and our lake is not chlorinated," Dieck added. "Our inflatable water features have numerous common touch points that staff cannot sanitize frequently enough. Given that social distancing is recommended, we can't safely perform in-service staff training, since it requires hands-on rescue training."
