The presence of toxic algae has caused Campus Lake to close indefinitely.

People are advised to avoid skin contact with the water, as it can cause rashes. Animals swimming in the lake or drinking the water may contract illnesses that have the potential of being fatal, according to Friday’s press release. 

Kevin Bame, vice chancellor for administration and finance, said fishing and boating on the lake are temporarily banned. 

The algae, which caused the lake to close last fall, is naturally occurring and depletes the oxygen level of the water, a process that may cause organisms including fish and other animals in the water to die. 

Bame said the algae will dissipate, but the university has no prediction as to how long the lake will be closed. Meanwhile, warning signs are being posted around the lake.
