Lake of Three Fires is temporarily closed for swimming.
A Missouri resident that recently swam in Lake of Three Fires has a confirmed infection from Naegleria fowleri, commonly known as the “brain-eating amoeba.” The Centers for Disease Control and Prevention and the Iowa Department of Health and Human Services are testing the lake to confirm whether or not the amoeba is present. The process will take several days and the beach will remain closed during that time.
