If you see a HAB, avoid and report it.
Keep kids and pets away!

- We need pictures of the bloom, location of bloom*, and date and time when pictures were taken.
- *GPS coordinates are highly preferable but approximate address and nearby landmarks will also do.
- A trained HABs Harrier will respond, and take a sample for analysis if needed.
To see where on the lake HABs have been spotted:
Check out the following map provided by the Community Science Institute:

We would like to share with you the Cayuga Lake Watershed Network’s new HABs Video PSA. The 4-minute video was made by Carly Siege, our Communications Staff, to help inform the public of the threat of HABs, as well as how to spot them and how to report them.

HABs may be short-lived (appear and disappear in hours) or long-lasting (persist for several weeks). The lakes that are “always” on the list may be blooms in multiple locations or have a persistent bloom. These lakes may be more susceptible to HABs based on high nutrient levels in the water or because of the lake’s physical or land use characteristics. Some lakes are regularly posted on the notifications page as a result of persistent blooms and active surveillance.
The HABs notification page is updated every Friday, late spring through fall. Sometimes there may be a short lag between when a bloom appears (or disappears) and when the lake is listed (or delisted) on the webpage. Listings are moved to the HABs Archive page when a bloom is reported to be no longer visible or no new information was available to update the listing for three consecutive weeks.
Swimmers and recreational users should remember that health and safety cannot be assured outside of designated swimming areas- for more swimming information, visit DEC’s swimming webpage.

Harmful algal blooms, or HABs, occur when colonies of algae — simple plants that live in the water — grow out of control and produce toxic or harmful effects on people, fish and other aquatic organisms, mammals, and birds.
