An island that appears and disappears, moving through the water as if it were “alive.” No, it’s not about artificial intelligence, but about a natural phenomenon as mysterious as it is fascinating, observed in Williston Lake, an artificial reservoir of about 1,800 square kilometers in British Columbia, Canada.

The floating island, covered with trees and vegetation that appear to be in good condition, has been seen moving around at various points in the reservoir. Its dimensions are extraordinary: about 140 meters long and 70 meters wide, or approximately 10 thousand square meters.

The first footage was recorded in early August by several people boating in the area and quickly spread on social media. One of them was local resident Rocky Avery, who, after receiving information from a boater, contacted BC Hydro, the company responsible for managing the lake and WAC Bennett Dam.

At first, the company was skeptical about the reports. The reason was simple: in an era when images created by artificial intelligence are increasingly reliable, it was hard to believe that such an island could really exist.

But satellite images confirmed the phenomenon. BC Hydro analyzed images from Sentinel-2, a joint mission of the European Space Agency and the European Commission. According to the data, on July 21, before the photos spread on social media, a new land surface had appeared west of Finlay Bay, about 100 kilometers from the dam.

On August 5, it was no longer in that position, indicating that the mass had moved within the reservoir. Then, according to an update published by Avery, the island reappeared near the Ospika area.

The scientific explanation is less mysterious. Such floating formations, covered in vegetation, have also been documented in large artificial reservoirs in North America, Africa, and other regions.

They are created when rising water levels detach parts of the land and vegetation from the shores. In the case of Lake Williston, the situation is related to the fact that this year the reservoir reached maximum capacity for the first time in 14 years.

The rise in water levels has lifted the mass that has accumulated over the years along the shores, where trees and plants had taken root. Detached from the land, this mass has begun to float and move under the influence of the wind.

BC Hydro is not currently reporting any specific risks to navigation or dam infrastructure. However, to better understand what lies beneath this “living” island, an underwater expedition is expected to take place in the coming days.
