New video footage shows what a local man believes to be a sea serpent in British Colombia's Okanagan Lake.
Richard Huls shot the video while visiting a winery and, along with other people in the area, believes it to be the Ogopogo - Canada's version of the Loch Ness Monster.
He told the Vancouver Sun: 'It was not a wave obviously, just a darker colour. The size and the fact that they were not parallel with the waves made me think it had to be something else.
'It proves something is down there. Whether it's Ogopogo or not is a different story, but there is something at least down there.'
There have been around 1,000 alleged sightings of Ogopogo since 1860, but many have been dismissed as animals, like otters, or floating inanimate objects, like logs.
Benjamin Radford, from the Skeptical Inquirer science magazine, said he's not convinced, telling the Daily Mail: 'There are no humps, nor head, nor form – only two long, darkish, more or less straight forms that appear to be a few dozen feet long.
'Perhaps not coincidentally, Lake Okanagan has tens of thousands of logs harvested by the timber industry floating just under the lake's surface.'
