Water Resource Inventory Area 7 Geographic Response Plan (WRIA7-GRP)

Skykomish River

WRIA 7 is located north and east of the Seattle metropolitan area. The watershed is 1,978 square miles in size. Population density is greatest in the western portion of the planning area near the Puget Sound. The major cities within this area are Everett and North Bend. Smaller cities include Arlington, Carnation, Duvall, Granite Falls, Gold Bar, Index, Lake Stevens, Marysville, Monroe, Mukilteo, Sammamish, Skykomish, Snohomish, and Sultan.

Although this GRP encompasses the Snohomish River and its two major tributaries (the Snoqualmie and Skykomish Rivers), response strategies have only been developed for the Snohomish and Skykomish Rivers. Response strategies for the Snoqualmie River will be developed at a later date.

Interim Updates

In between plan updates, GRP strategies are tested during drills and actual spill events. The results of these tests may require changes to certain response strategies, notification strategies, staging areas, or boat launch locations. Eventually, these changes will be fully incorporated into the plan. Until that time, please use the updated strategy and information sheets below in lieu of that provided for similarly numbered locations in the published plan.

No interim updates currently available
