    "prose": "Boaters in northern British Columbia are being warned to stay away from a mysterious floating island that has reappeared on Williston Lake after drifting about 30 kilometres in two weeks. [^1]\n\nRocky Avery, a resident of British Columbia, spotted a large mass of green vegetation floating freely on Williston Lake while boating. [^2]\n\nSatellite imagery from the European Space Agency's Sentinel-2 satellite confirmed that the floating mass is a real object located in Williston Lake. [^3]\n\nLocal resident Rocky Avery posted videos on social media showing a large floating island covered in trees and vegetation moving across Lake Wabamun in British Columbia, Canada. [^4]\n\nA mysterious forested island approximately one hectare in size appeared in the Williston Reservoir in British Columbia, Canada, and was later confirmed to have moved and disappeared. [^5]\n\nBC Hydro spokesperson Bob Gammer said he initially thought reports of the island covered in trees and foliage on Williston Lake were a hoax, but satellite images confirmed its existence in mid-August. [^6]\n\nGammer said the island appears to be intact, is about 140 meters long and about 70 meters wide, and is naturally unstable, making it unsafe to climb onto or land a boat on. [^7]\n\nThe floating island, measuring about one hectare, disappeared and was then spotted again on Monday after travelling about 30 kilometres northwest on the reservoir. [^8]\n\nBarry officials noted that Williston Lake has reached full capacity for the first time in 14 years, and rising water levels likely tore a section of the vegetated shore loose. [^9]\n\nExperts describe the floating object as a giant raft of vegetation with interlocked roots rather than a traditional island. [^10]\n\nBC Hydro officials stated that record-high water levels, the first in 14 years, likely caused the island to form by freeing debris that was previously stuck along the shoreline. [^11]\n\nSatellite images from the Sentinel-2 system, operated by the European Space Agency, captured the green surface approximately 100 kilometers west of the W. A. C. Bennett Dam on July 21, 2026.
