MOREAU — The Moreau Lake beach has once again been closed because of an algal bloom, according to the state Department of Parks, Recreation and Historic Preservation.
"We do water quality inspections every day," Parks Department spokesman Dan Keefe said. "There was a visible bloom expected yesterday."
The beach was closed in July for the same reason.
According to the National Ocean Service, harmful algal blooms occur when colonies of algae -- simple photosynthetic organisms that live in the sea and freshwater -- grow out of control while producing toxic or harmful effects on people, fish, shellfish, marine mammals and birds.
Human illnesses caused by the blooms, the service says, can be fatal in rare cases.
Keefe said additional water tests will be conducted once the algae is "no longer visible," and updates will be posted online.
