Ross Island, River island in Willamette River, Portland, Oregon, US.
Four interconnected islands covering 400 acres in the Willamette River create a natural division with Holgate Slough on the east side.
The island underwent extensive sand and gravel mining operations between 1926 and 2001, resulting in excavation of two-thirds of its terrain.
The island bears the name of Oregon pioneer Sherry Ross and contains natural areas that support 50 bird species including eagles and herons.
Access to the island requires participation in organized volunteer work parties through Portland Parks & Recreation and community partners.
A lagoon formed by an artificial levee connects Ross Island to Hardtack Island, created in 1926 for dredging operations.
