Snohomish Basin Geographic Response Plan
The Washington Department of Ecology is updating the Snohomish Basin (formerly WRIA 7) Geographic Response Plan (GRP). An important part of the update process is hearing from the people who live, work, and play in the GRP area. To facilitate this, a public comment period will be open from September 14 to October 14, 2022.
The Snohomish Basin, also called Water Resource Inventory Area 7 (WRIA 7), consists of three main river systems and numerous tributaries. The headwaters of the Skykomish River and Snoqualmie River form in the mountains of the Cascade Range. These rivers flow west and converge to form the Snohomish River in the floodplains of the Snohomish Basin. The Basin drains 1,900 square miles from the west crest of the Cascade Range to Puget Sound near Everett, Washington. There are 2,718 miles of rivers and stream in the Basin. It is the second largest basin draining into Puget Sound. The Snohomish Basin includes the northeastern portion of King County and the south-central portion of Snohomish County. The Basin is located north and east of the Seattle metropolitan area. The North Central Puget Sound GRP neighbors the Snohomish Basin GRP to the west and north.
