- Spencer Island Wildlife Area Unit (wdfw.wa.gov)
The Spencer Island Unit is a flat, grassy intertidal complex ringed by mixed forest, located in the Snohomish River estuary. This unit offers waterfowl hunting, hiking, and wildlife viewing opportunities. A 1-mile, elevated trail is a special feature. The island is jointly-owned/managed by WDFW and the Snohomish County Parks and Recreation Department. In 2005, an act of nature breached a dike on the WDFW property on the northwest side of the island, restoring tidal influence to the area. WDFW and its partners are working together to continue restoration of the estuarine system.
