Ross Island is only open to the public through volunteer work parties.
At this time, access to the site is limited to individuals or small groups that volunteer on PP&R projects or those organized by our community partners: Bird Alliance of Oregon, Willamette Riverkeeper, and Urban Greenspaces Institute. When PP&R completes a habitat management plan for the site, it will also include access options. For now, the best way to see the island is by boat or from the Springwater on the Willamette and South Waterfront. Numerous paddle trips are offered by our community partners throughout the year.

Park history
Ross Island occupies the middle of the Willamette River in southwest Portland. Most of it is owned by Ross Island Sand and Gravel, a company that has mined river gravel there since the 1920s. On October 31, 2007, Dr. R. B. Pamplin, Jr. donated 44.83 upland acres, not including the lagoon shoreline edge, to the City of Portland.
Ross Island is part of the Holgate Channel and Oaks Bottom Wildlife Refuge complex. The complex makes up a significant regional fish and wildlife habitat and is one of the most scenic reaches of the lower Willamette River. It has been designated an Important Bird Area by the Oregon Bird Alliance because of it use by both migratory and resident birds. There is a bald eagle nest on the City’s parcel and a small Great Blue Heron rookery on the island’s northern tip, property owned by the Port of Portland.
Assessment dates are copied from the public Parks Amenities layer. Old dates mean this source does not publish a newer assessment for that asset, not that we have confirmed no newer internal inspection exists. PP&R does not publish itemized repair costs, so this ledger shows needs without dollar figures.
Public data does not currently flag repair candidates for this park. Additional PP&R maintenance exports can be added without changing the page structure.

The public asset layer includes `PictureID` and `Hyper_pic`, but those values point to PP&R internal file-share paths, not public image URLs. Asset-level inspection photos need a PP&R export or public ArcGIS attachments before this app can render them.
