Mysterious island emerges then disappears in…
An enormous tree-covered island mysteriously emerged in a distant Canadian reservoir before vanishing from sight just weeks later.
The weird floating landmass was noticed in British Columbia’s Williston Reservoir — a sprawling man-made lake north of Mackenzie — earlier this month, according to CBC.
Local Rocky Avery said pictures and video of the island had been taken by a boater and later shared with him before he posted them on social media, where they rapidly went viral.

“It was a pretty amazing sight to see, never seen anything like that in my 40 years in this country,” Avery told the outlet.
“There was a big fishing derby coming up, so I wanted to make sure everybody was aware of what was going on. And I wanted BC Hydro to know too that it was out there, just in case it was floating down their way.”

BC Hydro — a government-owned utility company that generates and delivers clean hydroelectric energy to most of British Columbia — initially questioned whether or not the mysterious island was real.
Spokesman Bob Gammer said he was skeptical about the unusual sighting because advances in generative AI have made it more and more troublesome to decide whether or not photographs posted online are genuine.
“It’s certainly something we’ve not heard of before,” Gammer said. “And with not very many people reporting it, it was difficult to locate.”
Even government-owned utility company BC Hydro initially questioned whether or not the mysterious island was real.
Satellite imagery dated July 21 finally confirmed the island was real and floating in the main physique of the reservoir west of Finlay Bay, about 60 miles west of the WAC Bennett Dam.
The island was estimated to be about 230 ft extensive and 460 ft long, masking roughly 105,000 sq. ft, practically the dimensions of two NFL soccer fields.
But by Aug. 5, the big landmass had vanished from satellite tv for pc imagery.

“We’ve been taking more updated snapshots and we can’t see the object anymore. So it’s disappeared now,” Gammer told CBC. “It doesn’t mean it’s gone to the bottom of the reservoir. It may have returned to a more sheltered area along the shoreline.”
Officials have a idea about how the runaway island emerged in the first place.
Gammer explained driftwood might have accrued along the shoreline over a number of years, with plants and trees finally taking root in the decomposing particles and creating a floating landmass.
The reservoir has been unusually full this yr following high winter snowpacks and regular summer season rain.
BC Hydro was compelled to open the WAC Bennett Dam’s spillways in June and July to release water.
“We haven’t had a full reservoir in 14 years,” Gammer said. “We can’t pinpoint the origin of this floating island [but that’s] one explanation that seems reasonable.”
Avery added that the unusually high water has also washed out shoreline sand dunes fashionable with quad bikers while dragging more trees and particles into the reservoir than normal.
“There’s areas we would never even drive a boat on before, and now we’re going up over top of it,” he said.
BC Hydro doesn’t anticipate the island to trigger any operational issues but is monitoring the reservoir in case the mysterious landmass resurfaces.
Williston Reservoir was created behind the WAC Bennett Dam in 1968 and is the seventh-largest reservoir in the world.
