Harmful Algal Blooms

Harmful algal blooms (HABs), also known as red tides, are currently impacting the Oakland Estuary, Lake Merritt and the Alameda City shoreline. Per the California Water Control Board’s guidance, it is highly recommended that people and their pets stay out of the water until the blooms dissipate. Contact with the algae blooms can cause skin irritation and burning eyes in humans and can cause more dangerous effects on dogs.
