SNOHOMISH RIVER

The 'Snohomish River' is a Washington river formed by the confluence of the Skykomish and Snoqualmie rivers near Monroe. It flows northwest entering Port Gardner Bay which is part of the Puget Sound system between Everett and Marysville. The Pilchuck River is its main tributary and joins the river at Snohomish. The river system drains the west side of the Cascade Mountains from Snoqualmie Pass north to beyond Stevens Pass.
Measured at Monroe, the Snohomish River has an average annual flow of 9,500 ft³/s.^[3] In comparison, the Columbia River, Washington's largest river, has an average annual flow of 190,000 cubic feet per second, as measued at The Dalles, Oregon.^[4]
