RICHMOND, Va. (WFXR) – The public has been advised by the Virginia Department of Health (VDH) to avoid portions of Lake Anna due to reports of harmful algae blooms.
These areas include the Upper and Middle Pamunkey Branches, as well as the Upper North Anna Branch of Lake Anna.
Algae blooms often occur when warm water and nutrients combine to make conditions favorable for algae growth. VDH says, while most algae species are harmless, some species may cause issues to wildlife, the environment, and people.
Some harmful algae, called cyanobacteria, can cause skin rash and gastrointestinal illnesses, such as upset stomach, nausea, vomiting and diarrhea.
The VDH is asking people to avoid contact with any area of the lake where water is green or an advisory sign is posted.
