HAB Data ViewerSatellite CyanoHAB Map | Pre-Labor Day Assessment 2018 | Archived Data
This map displays estimated amounts of cyanobacteria in large water bodies calculated from satellite imagery. The map includes approximately 250 waterbodies in California large enough to be detected by the satellite. It is designed as a screening level analysis tool. For example, if the satellite shows a potential bloom, this can prompt field verification and sampling to confirm the status of a potential cyanobacteria harmful algal bloom. Decisions for health advisory postings will be made based on results from water quality samples. No regulatory decisions, or signage postings, should occur based solely on information from the map. More information about freshwater harmful algal blooms can be found at: mywaterquality.ca.gov/habs
Important information about the satellite map:
- The map shows estimates of cyanobacterial abundance near the surface of a waterbody.
- The map does not show any information about toxin concentrations and public health advisories.
- The map shows data collected over a 10-day window and does not display real-time conditions at a waterbody.
- All data on the map are currently considered provisional.
