Harmful Algae Bloom Advisories Expanded for Orange County at Lake Anna
ORANGE COUNTY, Va. – All portions of Pamunkey Branch, North Anna Branch, Lake Anna State Park Beach, as well as the Main Branch of Lake Anna from the “Splits” to the confluence of Pigeon Run above Route 208 in Orange, Louisa and Spotsylvania counties are experiencing a harmful algae bloom (HAB).
The public is advised to avoid contact with specific areas of the lake until algae concentrations return to acceptable levels.
Some harmful algae, called cyanobacteria, can cause skin rash and gastrointestinal illnesses, such as upset stomach, nausea, vomiting and diarrhea.
Samples results from collections on August 2 indicated that at eight locations in the North Anna, Pamunkey Branches, and at Lake Anna State Park, swimming advisories are necessary due to unsafe levels of cyanobacteria, which have the potential to produce toxins.
People and pets are advised to avoid swimming, windsurfing and stand-up-paddle-boarding, as well as other activities that pose a risk of ingesting water.
Activities such as boating may continue with proper precaution in advisory areas.
Follow-up monitoring above Route 208 on the lake is planned (weather permitting) for the first week of September.
