Where is Allen Creek?

Allen Creek is a tributary to the Snohomish River Estuary, draining much of the Eastern portion of suburban and rural Marysville. It is home to several species of salmon and Bull Trout. The creek empties into Ebey Slough after passing through the Qwuloolt Estuary Restoration Project that was completed by the Tulalip Tribes in 2015.

What's the problem with Allen Creek?

As rural and suburban Snohomish County populations continue to rise, the Allen Creek watershed has lost much of its natural function. The creek is listed as an impaired stream by the Washington Department of Ecology for low dissolved oxygen levels. Much of the Allen Creek floodplain has become dominated by invasive plant species that don’t provide enough shade, which increases water temperatures. High water temperatures lead to low dissolved oxygen levels, which can be lethal for fish.

What's being done to help Allen Creek?

The Snohomish Conservation District has secured 2 grants from the Washington Department of Ecology to restore 22 acres of Allen Creek at Jennings Park in Marysville. These restoration projects will focus on planting the floodplain with native trees and shrubs that will replace the invasive plants and provide the much needed shade to the creek. In addition to the planting, the Snohomish Conservation District will also be hosting volunteer events, youth educational opportunities, and a septic workshop for landowners in the Allen Creek watershed.

Funding Available for More Tree Planting
