A small algae bloom has taken over some parts of Lake Audubon.

Reston Association is asking members to avoid contact with the water, which could contain algae that is “potentially harmful.” Pet owners should also make sure their pets avoid ingesting or coming into contact with the water.

The association has no immediate plans to treat the algae, which frequently makes appearances at the lake at the end of the summer.

“Forecasted rain and cooler temperatures will improve the conditions of the lake,” according to RA.

Although algae blooms are common, a major algae bloom at Lake Thoreau has raised concerns about overall lake management and environmental health. RA plans to host a special meeting about the bloom at Lake Thoreau later this month.
