Update, December 22nd: The archived HABs notices for 2023 show that HABs were reported as present in Prospect Park Lake from May 25th through October 27th.
Still, the New York Department of Environmental Conservation emphasizes that
"HABs may occur on waterbodies throughout the year, although fewer blooms occur as water and air temperatures decrease. DEC recommends avoiding contact with floating mats, scums and discolored water at any time."

The New York State Department of Environmental Conservation and the New York State Department of Health have announced
the start of the 2023 online New York Harmful Algal Bloom System
(NYHABS) interactive map. Click OK to view the map.
DEC is asking the public and trained algal
bloom samplers to send reports of HABs with photos electronically via a simple, mobile phone-friendly form.
Once evaluated by DEC and DOH, reports are posted to the NYHABS page, providing easy access to inform the public about HAB locations in New York.
Most algae blooms are harmless. However, exposure to toxins and other substances from certain HABs can make people and animals sick.
HABs have been monitored closely across New York State since 2012.
DEC’s Division of Water recently published an analysis of HABs titled: “Detections of cyanobacteria harmful algal blooms (cyanoHABs) in New York State, United States (2012–2020).”
HABs present several management challenges, and this study and other
research help advance the understanding of HABs to inform sound,
scientifically driven, decision-making to protect public health and the
environment.
When it comes to HABs, DEC encourages New Yorkers to:
- Know It – HABs vary in appearance from scattered green dots in the water to long, linear green streaks, pea soup, or spilled green paint to blue-green or white coloration.
- Avoid It – People, pets, and livestock should avoid contact with water that is discolored or has algal scums on the surface.
- Report It –The public should report a suspected HAB through the NYHABs online reporting form available on DEC’s website. Report health concerns related to HABs to DOH at harmfulalgae@health.ny.gov, or contact your local health department.
For more information about HABs, visit DEC’s Harmful Algal Blooms (HABs) webpage.
You can download the HABs brochure and program guide, which includes
information and links to resources regarding bloom prevention,
management, and control.
