Officials from it "in a large stretch from Kingston to Norrie Point in Staatsburg."

After testing, officials confirmed it as Microcystis, which is a cyanobacteria that can produce harmful toxins.

"This is the largest cyanobacteria bloom we have seen in almost 40 years of monitoring the Hudson. Our scientists are working to understand possible causes. People and pets should avoid contact with impacted waters," Cary researchers told Hudson Valley Post.

The bloom is very dangerous for dogs, officials say.

Officials later confirmed more harmful algal blooms (HABs) in the Hudson River near Beacon, Hyde Park, Tivoli, and Hudson, as well as in the Wallkill River and Rondout Creek.

“The magnitude and extent of this cyanobacteria bloom is unprecedented, and concerning. While Microcystis is often observed in the Hudson, and sometimes produces blooms, this is by far the largest bloom we have observed,” Dr. Chris Solomon, a senior scientist and aquatic ecologist at Cary Institute, stated.

Report Algal Blooms

Officials want Hudson Valley residents to report algal bloom on the Hudson or other waterways to the NYS DEC’s Suspicious Algal Bloom Report or by email HABsInfo@dec.ny.gov.
