The State Land Inventory System is a collaborative effort with participation from all land-owning State of Oregon agencies. The layer is the most current published statewide dataset for State of Oregon land ownership. The State Land Inventory System tracks land that has been assigned a tax lot by county assessor's offices and also tracks State mineral (subsurface) ownership. The data does not include public rights of way (highways, roads and streets) or waterbodies which have not been assigned a tax lot by a county assessor. While efforts have been made to ensure the accuracy of the data, the managing agency for any individual parcel should be contacted to verify land ownership and boundaries. The originating deed(s) will need to be referenced to ascertain whether there are any reservations or exceptions that affect ownership rights. The data is known to have gaps and inconsistencies. Reach out to the maintenance contact to correct data errors.

For questions about the layer contact the Oregon Department of State Lands Ownership Specialist at ownership@dsl.oregon.gov.
