Below Mud Mountain Dam the White River enters the greater Tacoma metropolitan area. It flows between the cities of Buckley and Enumclaw, after which it makes a large bend northwest and then southwest, essentially flowing around Lake Tapps. North of the lake, the White River flows through the Muckleshoot Indian Reservation. Below that, to the west of Lake Tapps, the White River enters a broad floodplain and flows past the city of Pacific before emptying into the Puyallup River at Sumner.
