The Fate of a Lake After a Dramatic Mining Disaster

by Sarah Stanley 9 September 202212 October 2022

Researchers tracked long-term sediment dynamics in Canada’s Quesnel Lake following the 2014 failure of a dam that spilled record-breaking amounts of contaminated mining waste.

A boy in a striped t-shirt and shorts steers a long, narrow, and shallow boat with a long pole across a shallow body of water. The boat is laden with rocks. In the background is a marshland with a small group of people and a few tents, and beyond that are forests and mountains. One patch of forest on the right side of the mountains has been stripped bare by a past landslide.
