On July 15, the Indiana Department of Natural Resources reported seeing blue-green algae in Lake Monroe areas near Fairfax and Paynetown state recreation areas.
Blue-green algae is often visible on the surface of the water in a large layer of its own. However, it can appear reddish-purple or brown and can sometimes occur beneath the surface, where it isn’t visible.
In its advisory alert, the DNR said algae levels can be higher in the summer, but it’s important for people to avoid direct contact with the algae and swallowing any of the water.
At this time, the DNR allows boating and swimming but alerts pet owners to avoid putting pets in water or allowing them to drink algae-filled lake water.
According to a Herald-Times article, “exposure to blue-green algae can cause rashes, irritation of the skin and eyes, nausea, stomachaches and tingling in fingers and toes.”
The publication also said that the algae produce toxins that can cause beaches in state areas to close if produced at high enough levels.
If any person is in contact with the water, they should bathe or shower with warm and soapy water, the alert said.
