Toxic Algae Advisory for Black Lake

A toxic algae bloom in Black Lake means people and pets are advised to stay out of the water. Swimming or water-skiing in water with algae toxins or drinking it can lead to serious illness.

The county's Environmental Health Division has issued a Toxic Algae Advisory for Black Lake, and swimmers are advised to stay out of the water at Kenneydell Park until further notice. People who access Black Lake from boat ramps, private beaches or other access areas should also not swim, water ski, or allow their pets to swim in Black Lake until further notice.

Warning signs will be posted at public access points around Black Lake. The lake will be monitored weekly until the algae bloom is over and the advisory can be lifted.

While not all algae blooms are toxic, some algae can produce toxins that can harm the nervous system, the liver, the skin, and the stomach and intestines.

Experts from the county's Environmental Health Division also warn swimmers, water-skiers and boaters to be cautious around any waters with algae blooms. A few simple tips can help prevent illness from algae:

  • Avoid swimming, wading, wind surfing and water-skiing in waters where algae blooms are present.

  • Don't drink untreated surface water.

  • Clean any fish you catch thoroughly if you see algae blooms. Before eating, remove the internal organs, which may contain harmful algae toxins.

  • Keep pets and livestock out of waters with algae blooms.

  • Avoid areas of scum when boating and clean your boat thoroughly.
