White River

The White River is a glacially-borne river system that originates on the northeast face of Mount Rainier. The river appears white during summer when it carries a suspended load of fine sediments from glacial melting known as glacial flour.

The King County portion of the White River flows between the Cities of Enumclaw and Buckley, then through the Muckleshoot Indian Reservation and then along the Cities of Auburn, Algona and Pacific, leaving King County near the City of Sumner to feed the Puyallup River, which enters Puget Sound at Commencement Bay in Tacoma. The White River channel forms a portion of the boundary line between King County and Pierce County from the confluence with the Greenwater River.

Mud Mountain Dam has had a significant effect on flooding in the White River since its completion in 1948. Puget Sound Energy's diversion of flows since 1912 for hydropower generation through Lake Tapps also has had an effect on the river flow.

Industrial and residential land uses are common along the downstream portion of the basin. The lower 11 river miles of the White River, are lined by revetments and levees in a section that was channelized in the early 1900s through the Inter-County River Improvement Agreement. On the Muckleshoot Indian Tribe Reservation and upstream, the river flows through the White River canyon, a deep and generally undeveloped valley along the King and Pierce county line. Above the dam, the watershed is largely undeveloped.
