Visit NYHABS, DEC’s harmful algal bloom notification map, to view locations of current freshwater HABs in New York State. Each yellow dot on the map represents a HAB reported in the past two weeks. Click on a dot for more information, including the date it was reported, the waterbody name, and pictures. Click on the arrow at the bottom of the screen to view a list of reported HABs.
Know it. Avoid it. Report it.
If you see a HAB, please use the new reporting form to submit a report to NYHABS. Because waterbodies may have HABs that have not been reported to DEC, we recommend avoiding contact with floating mats, scums and discolored water.
If you, your family, or pet have been in contact with a HAB, please rinse with clean water and report any symptoms to your local health department.
