Today, the Department of Water Resources (DWR) urges people to avoid physical contact with water at Castaic Lake in Los Angeles County until further notice due to the presence of blue-green algae. People should also avoid eating fish or shellfish from the lake. This week’s lab results show an increase in toxin levels. A danger advisory was put in place today, and remains in effect for the entire Castaic Lake, except Castaic Lagoon, until further notice. It is advised for people and pets to stay out of the water and avoid contact with algal scum in the water or on shore. Boating is allowed, but water-contact recreation and sporting activities are not considered safe due to potential adverse health effects.
