MOREAU — Swimming at Moreau Lake State Park was slated to resume at 10 a.m. Friday, weather permitting, according to a State Parks, Recreation and Historic Preservation spokesman.
Park officials closed the lake to swimmers on Tuesday, due to a potentially harmful algal bloom at the park, located on Old Saratoga Road.
The park remained closed on Wednesday and Thursday.
A post on the Friends of Moreau State Park's Facebook page on Wednesday stated, "Tests just released confirm the presence of Harmful Algae Bloom (HAB) in the water. Signs have been posted all around the park warning of no swimming for people and pets."
The water was tested daily, as a change in weather — rain, less humidity and lower temperatures — could impact the water quality, stated the Facebook post.
The post also said while swimming was not allowed at the park during the harmful algal bloom, boating and fishing were permitted.
According to information on the state Department of Environmental Conservation's website, most algae are harmless and naturally beneficial. But certain types of algae can grow quickly and form blooms, which can cover all or portions of a lake, the DEC said.
"Even large blooms are not necessarily harmful. However some species of algae can produce toxins that can be harmful to people and animals."
Last Saturday, a power outage forced the beach to close during morning hours. And in June, officials posted warnings about "swimmer's itch," caused by common lake water organisms.
The beach is located off Old Saratoga Road.
Updates will be posted to the state Parks, Recreation and Historic Preservation website, as well as on the Friends of Moreau State Park's Facebook page.
