Welcome to Everything Croton, a collection of all things Croton--our history, our homes, our issues, our businesses, our schools, our houses of worship--in short, EVERYTHING CROTON.

Hudson RiverNet: News from the Hudson River Estuary Management Program

Harmful algal blooms (HABs) are being reported on the Hudson River Estuary. HABs in freshwater (lakes, ponds, rivers, and streams) generally consist of visible patches of cyanobacteria, also known as blue-green algae, are microscopic organisms that can form dense blooms in surface waters and can accumulate on rocks and along shorelines. Cyanobacteria are naturally present in low numbers in most freshwater and marine systems. There are many types of non-toxic green algal blooms. View images of non-toxic algal blooms and harmful algal blooms on DEC's Harmful Algal Blooms website.

Avoiding HABs: People, pets and livestock should avoid contact with water that is discolored or has algal scums on the surface.  

Reporting HABs: We encourage anyone who notices a HAB to report it to the NY HABS online Suspicious Algal Bloom Report Form. If possible, attach digital photos of the suspected HAB in the web form.
