Harmful Algal Bloom Notifications

Message from the Village of Dobbs Ferry Stormwater Management:

Harmful Algal Bloom Notifications

New waterbodies with harmful algal blooms have been added to the New York State Department of Environmental Conservations, (DEC), Harmful Algal Blooms Notifications webpage.

There are currently 18 waterbodies with blooms on the list.

KNOW  it.  AVOID  it.  REPORT  it.

Because waterbodies may have harmful algal blooms that have not been reported to the DEC, we recommend avoiding contact with floating mats, scum and discolored water.

Avoid and Report Suspected Blooms

Harmful algal blooms can look like:

  • White, blue or green spilled paint
  • Green streaks on the surface of the water
  • Green dots in the water or green globs on the surface of the water
  • Pea soup

To learn more about what harmful algal blooms look like, visit the DEC’s photo gallery of harmful algal blooms.

If you suspect you have seen a harmful algal bloom, or you, your family, or pet have been in contact with a harmful algal bloom, please follow the instructions for reporting a bloom to DEC.
