A floating island appeared and disappeared on Williston Lake in British Columbia over the summer, sparking international attention after a viral video was posted by local resident Rocky Avery. The island, measuring 230 feet by 460 feet, was initially spotted about 60 miles west of the W.A.C. Bennett Dam and later went missing from satellite images before being rediscovered about 20 miles northwest of its original location. BC Hydro spokesperson Bob Gammer confirmed that floating islands can form on shorelines over years and detach in certain conditions, such as stormy weather or flooded shores. The island's reappearance has been monitored by BC Hydro through satellite images and eyewitness reports, with no animals spotted on the island but many species having crossed oceans and reached new continents using these natural rafts before.

Why this leaning score
This article does not take a side on a contested political
question, so it has no leaning score. That is an
answer rather than a gap: a match report or a rescue can be warmly
or critically written without being left or right, and scoring it
anyway is how approval of a subject gets recorded as a political
position.

An island that appeared to suddenly materialize, then vanish, on Williston Lake in British Columbia over the summer was rediscovered on the massive reservoir on Monday.

Once you’ve taken that all in, let’s ask the important question: How the heck did that happen?

The existence of the disappearing island—a floating mass of trees and vegetation that measures about 230 feet by 460 feet—sparked international attention last month after Rocky Avery, a local resident, posted a viral video of it that was sent to him by one of his boater friends, according to CBC News.
Bob Gammer, a spokesperson for BC Hydro, was initially suspicious that the video might be AI, but confirmed it was authentic after spotting the island drifting about 60 miles west of the W.A.C. Bennett Dam in satellite images taken on July 21.
uncertain
it → disappear → July
In satellite images from August 5th and circulated last week, it was no longer visible, sparking a search over the past few days that led to its rediscovery about 20 miles northwest of where it had previously been spotted.
asserted
it → circulate → rediscovery
“We had some earlier satellite imagery that confirmed that this wasn't just a hoax or some kind of AI thing, and that it really was real,” Gammer told 404 Media in a call.
asserted
Gammer → have → call
“Since then we've had more photos from people on their boats on the water sailing right up to this island, and additional satellite imagery that puts it all together to say that this is a real thing.
asserted
this → have → it
It’s a sizable island.”
asserted
It → ’ → ?
As it turns out, this isn’t a new phenomenon—though Gammer said it hasn’t been reported on Williston Lake before.
asserted
it → turn → Lake
Floating islands form on shorelines over many years, as natural rafts made of driftwood can allow plants and trees to grow above the water.
asserted
plants → float → water
These platforms can then detach in certain conditions, such as stormy weather or flooded shores, allowing them to meander into the water.
asserted
them → detach → water
Williston Lake is a reservoir created by the massive W.A.C. Bennett Dam, which stands more than 600 feet high.
asserted
which → create → Dam
Due to high snowpack and precipitation, the dam was opened in June and July, filling the reservoir for the first time in 14 years, according to Gammer.
uncertain
dam → open → Gammer
These high water levels, in addition to strong winds, likely dislodged the island, allowing it to float freely in the water.
asserted
it → dislodge → water
“This is all brand new to us,” Gammer said.
asserted
Gammer → say → us
“We've never seen anything like this on the reservoir.”
asserted
We → see → reservoir
BC Hydro is urging boaters to keep their distance and not to step on the island.
asserted
Hydro → urge → island
Despite its size, the forested mass is structurally flimsy and hazardous to walk on.
asserted
mass → walk → size
Other than birds, no animals have been spotted on the island.
asserted
animals → spot → island
However, animals have accidentally been swept away on these natural rafts; indeed, many species have crossed oceans and reached new continents this way.
asserted
species → sweep → continents
The island doesn’t pose any risk to the dam or vessels, and its journey around the lake is now being monitored by BC Hydro through satellite images and eyewitness reports.
asserted
journey → pose → images
This waterborne woodland may disintegrate over time, or become reattached to the shoreline.
uncertain
woodland → disintegrate → shoreline
If it survives until winter, it could be frozen into the ice and perhaps thaw out again in spring.
uncertain
it → survive → spring
“It's a break from everyday reality, and so it's really captured a lot of attention,” Gammer said.
asserted
Gammer → capture → attention
“There's a lot of media interest, and it's been great to be able to tell the story.
asserted
it → be → story
And who knows how long this will last?
asserted
this → know → ?
I mean, in terms of its news value, I'm sure it'll disappear within a few days.
asserted
it → mean → days
We'll be monitoring it, and if there's anything exciting about it, we may be able to tell that story too.”
uncertain
we → monitor → story
