Harmful Algal Blooms (HABs)
For current HAB conditions in California's Lakes, and to report HAB incidents in lakes you observe - visit the California Harmful Algal Bloom Portal, the central resource for HABs in our state. Be sure to view their improved HAB Incident Report Map, an interactive tool to view up-to-date and historical HAB incidents recorded across the state.
For additional information, see the EPA's comprehensive resource on Cyanobacterial Harmful Algal Blooms in Water. Which includes this 2019 Fact Sheet for a rundown of their guidelines for recreation.
