Toxic blue-green algae warning for Lake Del Valle: Park District
The East Bay Regional Park District’s Water Management Department has issued an advisory for toxic blue-green algae at Lake Del Valle in Livermore, Shadow Cliffs in Pleasanton, and other swimming areas around the East Bay. “Blue-Green Algae (also called cyanobacteria) are natural organisms that are present around the world in ocean and fresh water,” the park district reports on its website. “Certain conditions – low water levels, limited water circulation, increased temperature and light, among other factors – can cause blue-green algae to bloom and, in some cases, release toxins. Scientists do not know what causes the blue-green algae to become toxic. We do know that these blooms are increasing around the world.” Blue-green algae was first detected at an East Bay Regional park in 2014 and has been a constant threat ever since. In face, algae blooms and toxins have been observed at all major Park District water bodies.
