Greenwater River

The Greenwater River is a river in the U.S. state of Washington. Its watershed drains a portion of the Cascade Range east and northeast of Mount Rainier, including parts of the Norse Peak Wilderness. The Greenwater River flows into the White River at Greenwater, which eventually flows into Puget Sound via the Puyallup River. The Greenwater River defines part of the boundary between King and Pierce counties.
