The Raging River is a modest tributary to the much larger Snoqualmie River in western Washington State in the United States. It is located in the western foothills of the Cascade Mountains in east central King County, Washington. It gets its name from the large amount of water it sometimes carries. The record discharge at the gaging station is over 4000ft3 per second. The Raging is a salmon-bearing river and supports one-fifth of the Snoqualmie River's chinook runs.The river begins in the valley formed by Rattlesnake Ridge to the east Taylor Mountain to the west in the Raging River State Forest, managed by the Washington Department of Natural Resources. It flows northwest crossing State Route 18 and then continues north past Tiger Mountain, crossing Interstate 90 near Preston, Washington and joining the Snoqualmie River near Fall City, Washington. The Raging River watershed is part of the larger Puget Sound drainage basin. The average annual flow in the river is 149ft3 per second and the drainage area is 32 square miles.
