New York ( CNN ) -- Beachgoers are being warned to stay out of the water this weekend at four popular beaches around New York City after raw sewage from a Manhattan plant spilled into the Hudson River , authorities said . Health advisories also have been issued for portions of the Hudson River , the East River , the Harlem River and the Kill Van Kull , cautioning people against participating in water-related activities such as canoeing , kayaking and swimming , according to the New York City Department of Health .

The sewage spill was stopped Friday night , and two of the engines damaged by the fire have been brought back online , the department said . The health advisories were issued for South Beach , Midland Beach and Cedar Grove Beach on Staten Island , and Sea Gate in Brooklyn , according to the release .
