Mysterious floating island suddenly vanishes from massive lake
Imagine spotting what looks like a tree-covered island the size of nearly two football fields floating across a lake. Then imagine checking back a few weeks later and finding that it has seemingly disappeared.
That is what happened at British Columbia's Williston Reservoir, where a bizarre floating island emerged earlier this summer before vanishing from satellite images. Was the island even real or was someone messing around with AI, perhaps? Read on for answers.
The floating island was actually real
Photos and videos of the strange landmass began circulating online after a boater spotted it in Williston Reservoir, a massive man-made lake in northern British Columbia. The sighting quickly went viral, but BC Hydro was not immediately convinced.
Thanks to the rise of generative AI, an unusual photo on social media is no longer automatic proof that something actually happened. Officials initially struggled to verify the reports because so few people had spotted the island.
Fortunately, satellite imagery came to the rescue. Images captured on July 21 confirmed that the island was very real and floating in the reservoir's main body. And this was not some tiny patch of weeds. The landmass measured an estimated 230 feet wide and 460 feet long, covering approximately 105,000 square feet. That's nearly the size of two NFL football fields floating around a lake.
Where did an entire floating island come from?
The leading theory among officials is that years of driftwood may have accumulated along the reservoir's shoreline. Over time, plants and trees took root in the decomposing mass of wood and debris, eventually creating a gigantic floating island.
Think of it as nature accidentally building an extremely large raft and then adding a forest.
This year's unusually high water levels may have finally set the whole thing loose. Williston Reservoir hasn't been this full in 14 years, thanks to heavy winter snowpacks and consistent summer rainfall. BC Hydro was even forced to open the spillways at the nearby W.A.C. Bennett Dam in June and July to release excess water. All that extra water may have helped turn a stationary pile of driftwood into a free-roaming island.
Then it disappeared
By August 5, officials could no longer find the floating island in updated satellite imagery. It was gone. Vanished. Apparently deleted from the map. But officials don't believe the island necessarily sank to the bottom of the reservoir.
The more likely explanation is that it drifted into a sheltered area near the shoreline, where satellite images couldn't easily distinguish it from the surrounding landscape. So somewhere out there, there could still be a 105,000-square-foot island hanging out where nobody can see it.
Nothing to worry about
For now, BC Hydro does not believe the floating forest poses a threat to the reservoir or the nearby hydroelectric infrastructure. But officials are keeping an eye on the situation in case the runaway island decides to make another appearance.
