Updated at 3:40 p.m. — An algae bloom was spotted this morning in Lake Anne, joining blooms on Lake Thoreau and Lake Audubon, Reston Association says.
“At this time, Reston Association has determined that treatment of the blooms would not be beneficial, as a mass die-off of algae after treatment would cause a dip in otherwise healthy oxygen levels, therefore posing significant risk to fish and wildlife in the lake,” the organization said, advising residents and pets to avoid contact with the affected lakes.
