The Indiana State Department of Health cautions Hoosiers of possible high levels of blue-green algae, also known as Cyanobacteria, at many of Indiana's reservoirs and lakes. Swimmers and boaters should be careful in all recreational waters during this time of the year. Precautionary measures include avoiding contact with visible algae and swallowing water while swimming. Take a bath or shower with warm, soapy water after coming in contact with untreated water in ponds and lakes, especially before preparing or consuming food. Pets and livestock should also not be allowed to swim in or drink untreated water from these sources. Exposure to a blue-green algae during recreational activities such as swimming, wading, and water-skiing may lead to rashes, skin, eye irritation, and other uncomfortable effects such as nausea, stomach aches, and tingling in fingers and toes. If you should experience any symptoms after water recreational activities, please contact your doctor.
These are the most recent cyanobacterial cell counts. For protection of human health, the World Health Organization uses a guideline level of greater than 100,000 cells/ml for a high risk health alert in recreational waters.
