A Mercer County lake has become the third lake in the state to be closed to swimming due to a dangerous algae bloom.

Swimming, boating and fishing are prohibited in Rosendale Lake at Mercer Meadows Park in Pennington due to the dangerous algae, according to the New Jersey Department of Environmental Protection.

The park remains open, and visitors are still allowed inside. But they are advised to avoid contact with the water. The algae can cause abdominal pain, vomiting, headaches, nausea, flu-like symptoms, and blistering around the mouth.

This is the same type of algae that is impacting Lake Hopatcong and Spruce Run Reservoir. Officials say that they do not have a timeline as to when the bodies of water will be safe.
