A massive landslide has blocked the Chilcotin River in British Columbia, creating an imminent risk of flash floods and prompting the evacuation of dozens of properties. The landslide, which is approximately 30 meters deep and 600 meters long, has created a natural dam, causing water to back up and potentially breach the debris, threatening downstream areas. The blockage poses significant risks to local salmon populations, particularly sockeye and chinook, which are already struggling due to warmer river temperatures. Emergency officials have issued flood warnings and evacuation orders, affecting around 12 homes and 60 properties. The Tŝilhqot'in National Government and Cariboo Regional District are closely monitoring the situation, with updates expected as conditions evolve. The environmental impact on First Nations communities and local wildlife could be devastating if the natural dam fails.
