Reston Association issues all-clear after algae fades from Lakes Anne and Audubon

With a new month on the horizon, algae blooms at three lakes in Reston appear to be turning a leaf.

Warnings to avoid making contact with Lake Anne and Lake Audubon have been lifted after an algae bloom took over some parts of the lakes since mid-November.

A spokesperson for Reston Association, which manages the lakes, told FFXnow the decision was made after evidence of algae was no longer present.

Out of an abundance of caution, however, a warning for Lake Thoreau remains in place, according to Reston Association.

Blooms of algae emerged in Thoreau and Audubon early this fall and lingered as a result of the season’s warm weather, according to RA. Another bloom was spotted in Lake Anne on Nov. 16.

At that time, RA urged residents to avoid contact with the water, though the risk of incidental exposure risk is low during this time of the year.

Staff decided against treating the bloom, which would have disrupted oxygen levels in the lake, potentially harming fish and other wildlife.
