A densely wooded island surfaced unexpectedly on a lake in western Canada, measuring approximately 150 meters (500 feet) in length and 75 meters (250 feet) in width. This sudden emergence caught the attention of local residents and experts alike, as the landmass was absent from all maps and navigation charts.
A boater recorded a video of the island, showcasing nearly 100 trees swaying in the lake’s waves. Remarkably, within just a day, the island vanished.
Recently, the island reappeared, this time nearly 32 kilometers (20 miles) away from its initial site, prompting residents to question how such a sizable landform could simply disappear and reemerge in a different location.
This unusual phenomenon took place in Williston Lake, a long and narrow reservoir that was formed after the W.A.C. Bennett Dam inundated the area in the early 1970s. Covering nearly 1,700 square kilometers (650 square miles), it is the largest freshwater body in British Columbia.
Bob Gammer, a representative of BC Hydro, the provincial utility that manages the dam and reservoir, remarked on the astonishing nature of the island when he first viewed the footage. He noted that in today’s age of artificial intelligence, corroborating evidence, such as eyewitness accounts, is crucial for validation. Fortunately, such evidence quickly emerged.
Satellite images confirmed the existence of the island, which is adrift in the main section of the reservoir, approximately 96 kilometers (60 miles) west of the dam.
BC Hydro attributes the island’s formation to years of unchecked plant and tree growth on woody debris along the reservoir’s more sheltered areas.
Floating islands similar to this have been observed worldwide, such as Wisconsin’s renowned Forty Acre Bog. The larger floating island found on Lake Chippewa consists of a blend of peat, mud, roots, and trees.
Measuring around 12,000 square meters (14,000 square yards), the British Columbia island is teeming with life, including birds and small mammals inhabiting its diverse mix of coniferous and deciduous trees. Observers believe that the submerged root systems may conceal some of the best fishing spots in the lake.
Gammer compared the growth conditions to hydroponics, stating, “Well-nourished trees thriving on a decaying nutrient source with ample water could develop quite rapidly.” He added that the reservoir’s water level is currently at its highest in 14 years, owing to significant winter snowpack and steady summer rainfall, which have raised water levels in both the Peace River and the lake.
With the right environmental conditions, BC Hydro suggests that the trees on the island could thrive for years, although the exact age of the trees remains unknown. Local speculation suggests that these trees may be decades old.
Gammer emphasized the uniqueness of the situation, stating, “It’s not just a collection of small shrubs; this is an island with substantial trees, and it’s something that requires a shift in perspective. It’s truly extraordinary.”
Rocky Avery, a longtime local resident and friend of the boater who posted the video online to alert others about a potential hazard, expressed enthusiasm about the island, saying he would “totally jump on that island if given the chance.” He remarked that while the outer parts might be unstable, the large trees at the center could provide a solid footing.
Gammer, however, cautioned against boaters trying to set foot on the island. He noted that video footage shows the trees swaying on a “delicate, thin layer of logs,” labeling the situation as “very unsafe” and “extremely unstable.”
Avery’s social media updates on the island sparked considerable excitement and coincidentally referenced the recent political climate in Canada. Following stalled trade discussions, U.S. President Donald Trump suggested renaming Lake Ontario, an announcement that has drawn ire and ridicule from Canadians.
One commenter on Avery’s post quipped, “I’m surprised Trump hasn’t named [the island] and claimed it.”
