The Fraser River is the longest river in British Columbia, stretching 1,375 km. It begins on the western side of the Rocky Mountains at Mount Robson Provincial Park, and ends in the Strait of Georgia at Vancouver.

In 1858, gold was discovered on sandbars south of Yale, setting off the Fraser River Gold rush.2
Floods are primarily caused by naturally occurring changes in the height of rivers, lakes and oceans. According to Public Safety Canada, floods are the most common natural hazard in the country and among the costliest. Historic floods have occurred across Canada, with many of the worst happening on major river systems that pass through populated areas. Scientists predict that flooding linked to the impacts of climate change will increase as the 21st century progresses, particularly in coastal areas of the country.
