LAKE ELSINORE, CA – AUGUST 25: In an aerial view, green water is seen during a harmful algal bloom (HAB) of blue-green algae, also known as Cyanobacteria, at Lake Elsinore on August 25, 2022 in Lake Elsinore, California. The city has closed the lake to all activities, including fishing, swimming and boating, due to the danger of serious illness or death in humans and animals. Fueled especially by drought and hot weather, California is experiencing some of the worst HAB outbreaks in the nation with an increase of more than 464 percent outbreaks in the past five years.
