Reston Lakes Clear Of Algae Bloom, Reopen For Recreational Use: RA

RESTON, VA — Reston Association gave the "all clear" on Thursday regarding the algae boom that recently appeared in Lake Audubon and Lake Anne.

RA's watershed staff and its environmental contractor, AEC, began to monitor the lakes when Dolichospermum, a potentially harmful cyanobacteria was discovered last week. After an inspection on Wednesday, they each determined that both lakes were clear for recreational use.

"The bloom began after hot weather allowed cyanobacteria to thrive, which was then enhanced further by an influx of nutrients that came from a water main break that flowed into Snakeden Branch last week," said Peter Lusk, RA's chief operating officer on Thursday.

RA alerted the community last week to stay out of the lakes until the "all clear" was given to limit residents and their pets' exposure to the cyanobacteria.

While residents may now safely use Lake Audubon and Lake Anne for recreational use, swimming remains prohibited in all of the bodies of water RA manages.

The "all clear" should come as welcome news to the organizers of the 2023 Lake Anne Cardboard Boat Regatta, which is scheduled to take place rain or shine on Aug. 19.

Hosted by the Reston Museum, the annual outdoor event held at Lake Anne Plaza is an opportunity for teams of all ages to build and decorate cardboard boats and take them out on the water.

Activities get underway at 12 p.m., when all boats are on display on the plaza. People will be able to vote on their favorite boats until 2 p.m.. Then, from 2 p.m. to about 4 p.m., participants will take their human-powered cardboard vessels out on the water in timed heats.

Participants and spectators are encouraged to grab food from Nordic Knot, Kalypsos's Sports Tavern, Big Wonton, Lake Anne Brew House, Lake Anne Coffee House & Wine Bar, Jimmy's Old Town Tavern, Cafe Montemarte, and (before 12 p.m.) the Reston Farmer's Market.

FGM Architects, Robert E. Simon Jr. Children's Center, Kimley Horn, 123 Junk, and Greater Reston Living are the admiral, race station and presenting sponsors for this year's Lake Anne Cardboard Boat Regatta.
