After Electron the river turns north and flows by the city of Orting, where it is joined by the Carbon River from the east. Like the Mowich, the Carbon River also originates at a glacier on Mount Rainier (the Carbon Glacier). The Puyallup continues its northernly course after Orting. At Sumner, the river is joined by the White River, another glacier-fed river. At the White River confluence, the Puyallup River turns northwest, flowing by the cities of Puyallup and Fife, and through the Puyallup Indian Reservation, before emptying into Commencement Bay at the Port of Tacoma, part of the city of Tacoma.
