LAKE COUNTY – Local health officials on Friday issued an environmental health advisory regarding the recent appearance of a type of blue-green algae.

During the past several days, Department of Health Services, Division of Environmental Health has received numerous inquiries regarding suspected raw sewage along the shores of Clear Lake near Austin Park, Clearlake Highlands and the inner harbor area of the City of Clearlake.

Upon initial investigation, the substance appears to be a blue-green algae species known as Aphanizomenon. The appearance of this form of algae easily can be mistaken as raw sewage.

According to the Lake County Water Resources Division of Public Works, recent weather and water conditions have been conducive to this type of algal growth.

Further analysis is in progress to confirm the exact species and to clarify any potential health impacts.

As a precaution, it is recommended that individuals of all ages and pets avoid swimming in or ingesting lake water in the affected areas.

Families should exercise caution in keeping children and pets away from the water.
