Mysterious floating island spotted on Canadian lake

A strange green mass covered with healthy trees has appeared on Williston Lake in Canada, drawing attention online and leaving its exact origins unclear.

Rockey Avery, a British Columbia resident and boating enthusiast, posted video of the floating “island.” Technically, it appears closer to a raft than an island, with trees and other plants growing on what looks like a floating base of driftwood.

BC Hydro spokesperson Bob Gamer initially viewed the reports with caution because the sighting had not been widely reported. “That’s certainly something we’ve never heard of before. And because it wasn’t reported by a large number of people, it was difficult to locate,” Gamer told the CBC.

A review of freely available Sentinel-2 satellite data from the European Space Agency found a small island-like green patch on July 21, 2026. It was about 100 kilometres west of the W.A.C. Bennett Dam. The patch did not appear in images from previous days, and its location afterward was unclear.

Avery said on Aug. 31 that the island had been found again, this time in the Ospika River, which flows into Williston Lake. He and his friends plan to film it from below the water next time. Gamer suggested the mass may have formed along the shore over several years before breaking free when reservoir levels reached a record high. BC Hydro released water from the dam in June and July after the reservoir reached full capacity for the first time in 14 years.
