The Cummins River is a tributary of the Columbia River that forms from the glacial meltwater of the Clemenceau Icefields. As the river flows down the western slope of the Continental Ranges, it forms a trio of spectacular waterfalls that cascade into and out of a pair of alpine lakes from which the park derives its name. The river continues down the valley before joining the southeastern arm of Kinbasket Reservoir.
