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 4,000 cubic feet (110 m3) per second.[2] The Raging is a salmon-bearing river and supports one-fifth of the Snoqualmie River's chinook runs.[3]

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 149 cubic feet (4.2 m3) per second[4] and the drainage area is 32 square miles.[5]


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 7,000 acres, filling a large gap in the Mountains to Sound Greenway.[3]

Hiking and biking[edit]

The Preston-Snoqualmie Trail follows along the Raging River and Preston-Fall City Road for a 3½ mile stretch and continues toward Snoqualmie Falls.[6] 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.


The lower half of the Raging River from Preston to Fall City is 5 miles (8.0 km) long and has been rated as a class III+ (difficult) section for kayaking.[7]
