Blue Green Algae Blooms

Levels of blue-green algae may be high during summer in some local lakes and reservoirs. Avoid coming into direct contact with the algae or swallowing lake water. Keep a close eye on pets or small children, who may ingest water containing toxins produced by these algae.

Exposure to blue-green algae during swimming, wading, and water-skiing can lead to rashes, skin, eye irritation, and effects such as nausea, stomach aches, and tingling in fingers and toes. After you swim, wade or ski, be sure to shower with warm soapy water.
