Harmful Algal Blooms - HABs 2020

DEC’s harmful algal bloom (HABs) notification season has begun. HABs notifications will be updated through the fall using an online reporting and notification system dubbed NYHABS. The system includes an interactive map that shows reports of freshwater HABs, as well as a new public reporting system.

Instructions on how to use NYHABS are on DEC's HABs notification page.

Know it:  If you see a HAB, please use the reporting form to submit a report to NYHABS.

Avoid it:  Because waterbodies may have HABs that have not been reported to DEC, we recommend avoiding contact with floating mats, scums and discolored water.

Report it: If you, your family, or pet has been in contact with a HAB, please rinse with clean water and report any symptoms to your local health department.
