The Montreal Gazette reported the 30-year-old woman was standing on a rock when she slipped and lost her balance, falling into Dorwin Falls, north of Montreal, at 2:30 p.m. today.
According to CTV News, the woman had only dipped her feet in the Ouareau River during the photo shoot, but her wedding dress became soaked with water, dragging her down.
She then slipped and was carried away by the current, they said.
The photographer and another witness tried to save her, according to police, but the dress was too heavy and they couldn’t pull her out of the water.
“I tried to save her. I tried, I tried, I tried,” the distraught photographer, Louis Pagakis, told CTV News.
He said the woman, who had been married in June, wanted some extra photos taken for her wedding album.
He said it was her idea to shoot some photos in the water.
The photographer and his assistant were taken to hospital suffering shock.
The woman's body was found by a rescue team of divers several hours later, the newspaper reported.
“The people who fall at that spot usually perish. It doesn't give you a chance, " said Sergeant Ronald McInnis from Surete Quebec.
USA Today reported the groom was not at the photo shoot at the time of the incident, explained McInnis, adding that the two witnesses who saw the woman fall were extremely distressed.
McInnes said that the forested waterfalls are about 60 feet tall at their highest point and that the current "is very violent, it's very rocky."
