Over the course of a few days in the spring of 2016 the flow of the river was changed.[4] Where the meltwater of the Kaskawulsh Glacier had been draining in two directions, now it was all draining into the south-flowing Kaskawulsh River, and further on into the Gulf of Alaska, drastically reducing the size of the Slims.[5] Researchers suggested the change in flow could be due to manmade climate change; this was the first time manmade climate change was implicated in the reorganization of a river.[6][7]
