There’s no swimming at Moreau Lake State Park.
The beach was closed for a second day on Wednesday due to concerns over algal blooms.
According to the park website, what was found in the water could be dangerous to humans.
Dog owners are also being told to keep their animals on land.
The beach will remain closed until the toxin levels are lower.
It's not clear how long that could take to happen.
