Toxic algae closes San Francisco Bay Area swim lakes

Toxic algae blooms have closed two more lakes east of San Francisco.

The East Bay Times reports ( ) that Lake Temescal in Oakland and Quarry Lakes in Fremont are closed until tests show that concentrations of the blue-green algae have subsided to safe levels.

Both parks, Temescal and Quarry Lakes Regional Recreation areas, will remain open for hiking, picnicking, and other activities.

A third lake, Lake Anza in Tilden Regional Park in Berkeley, has been closed since August because of the algae.

The cyanobacterium, which occurs naturally, can cause gastrointestinal problems and allergic reactions in people and sickness and death among pets and wildlife. It has blossomed during the state's drought.

Toxic algae has shown up in more than 40 state lakes and waterways from Los Angeles to the northern reaches of California, the highest count in state history.
