The 25-minute film follows Dr. Younes Alila, a professor of forest hydrology at the University of British Columbia, as he investigates the links between clear-cut logging in the Kettle River watershed and extreme flooding in Grand Forks, B.C. With compelling field footage and scientific insight, The Narwhal presents a documentary that reveals how loss of forest cover has triggered a cycle of flooding, landslides and drought — transforming the landscape and endangering communities downstream.
