For 300 years, glacial runoff was the major water source for Kluane Lake, flowing in by way of the Slims River. But in May 2016, Kluane Lake levels dropped precipitously. The problem was a case of "river piracy" — incredibly rare, and hugely significant. The terminus or end of the Kaskawulsh glacier had receded enough that a glacial lake that fed the Slims River suddenly drained when the glacier outflow found a new direction to a new river.
