A possible sighting of Canada’s version of the Loch Ness monster at a lake in British Columbia has stirred up the legend of the sea creature long-rumored to reside there.

A man visiting British Columbia’s Lake Okanagan claims he filmed video of what could only be the elusive monster, known to locals as Ogopogo. The 30-second video shows two long ripples in the water in a seemingly deserted area of the lake.

“It was not going with the waves,” Richard Huls, who captured the scene on camera during a visit to a local winery, told the Vancouver Sun. “It was not a wave, obviously, just a darker color. The size and the fact that they were not parallel with the waves made me think it had to be something else.”

Ogopogo is the Canadian version of Scotland’s famous Loch Ness monster. The first recorded sighting of the alleged creature in Loch Ness was nearly 1,500 years ago when a giant beast is said to have leaped out of a lake near Inverness, Scotland, to eat a local farmer. Since then, the legend has taken on a life of its own through first-person accounts of those who claim to have seen it and in public imagination.

As with Loch Ness, the Ogopogo phenomenon dates back hundreds of years and is believed to have its origins in native Canadian Indian folklore with a creature called N’ha-a-itk. The locals would not cross the area of the lake where they thought the monster resided without an offering to feed the monster if attacked.

Ogopogo is most commonly described as a 40- to 50-foot-long sea serpent. There have reportedly been thousands of sightings of the monster through the years, including a marathon swimmer in 2000 who claimed he saw two large creatures in Ogopogo’s likeness swimming with him at times. The lake has been searched and no concrete evidence of the monster has turned up. Still, the legend of the lake monster lives on.
