Raging River

The Raging River is a tributary of the 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 4000 ft3 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 and 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 149 ft3 per second and the drainage area is 32 square miles.

History
Until 2009, almost half of the Raging River basin was privately owned. In the spring of that year, the Washington Department of Natural Resources and King County partnered to purchase 7000 acre, filling a large gap in the Mountains to Sound Greenway.

Hiking and biking
The Preston-Snoqualmie Trail follows along the Raging River and Preston-Fall City Road for a 3½ mile stretch and continues toward Snoqualmie Falls. The trail is bike and dog friendly.

In the winter of 2012 the Washington Department of Natural Resources began a public planning activity to guide the development of recreation opportunities in the Snoqualmie Corridor, including specifically the Raging River State Forest.

Kayaking
The lower half of the Raging River from Preston to Fall City is 5 mi long and has been rated as a class III+ (difficult) section for kayaking.
