About Cedar River Watershed

The Cedar River Watershed is a critical protected area supplying clean drinking water to the Seattle metropolitan region, offering limited public access for hiking and nature study amid old-growth forests and pristine river corridors.

Wilderness Landscape & Natural Heritage

The Cedar River Watershed encompasses approximately 90,000 acres of forested land located southeast of Seattle in Washington State. Managed primarily by Seattle Public Utilities, the watershed is a vital natural resource that provides over 70% of the water for more than 1.4 million residents in the Seattle metropolitan area. The area is characterized by dense coniferous forests, including Douglas fir, western hemlock, and western red cedar, combined with riparian ecosystems along the Cedar River and its tributaries. The terrain is rugged with steep slopes, waterfalls, and deep river valleys. The watershed also serves as key habitat for wildlife such as black bears, cougars, Roosevelt elk, and numerous bird species. Historically, the watershed has been protected from extensive development or logging since the early 20th century, primarily to maintain water quality. Recreational opportunities here are limited and regulated to minimize human impact, featuring a few hiking trails like the popular 4.3-mile Long Trail and the Cedar River Trail, which provide scenic views of old-growth forest and river canyons. Visitors can enjoy wildlife viewing, photography, and quiet forest walks. Access is restricted during some seasons to protect spawning salmon and safeguard water quality. The area holds ecological significance due to its intact forest ecosystems and its role in regional water supply, making it a vital natural preserve with a balance between conservation and limited public access.
