The CA HABs Portal is the central resource for HABs in the state of California. HABs can pose a health risk to people and animals, harm aquatic ecosystems, and limit the use of drinking and recreational waterbodies due to the toxins, odors, and scums or mats they can produce.
The Portal is an informational resource for the public and also functions as a tool to support coordination with statewide partners to address HABs. The content is developed by the California Cyanobacteria and HAB (CCHAB) Network and participating state agencies.
The content in this Portal focuses on freshwater and estuarine HABs.
For information on marine (coastal) HABs, including red tides, please refer to the California Harmful Algal Bloom Monitoring and Alert Program (CalHABMAP) and CDPH's Marine Biotoxin Monitoring Program webpages.
