Washington State Department of Natural ResourcesThe NDMPL (Washington State Non-Department of Natural Resources Major Public Lands) data contains ownership parcels for Federal, State (excluding WA DNR), County and City lands within the State of Washington. It also includes Tribal administrative boundaries. The NDMPL data layer is a polygon dataset and does not contain arc attribute information for ownership boundaries. This data is not connected to WA DNR's Cadastre layers (these data include WADNR ownership, Public Land Survey System and other cadastral data). As updates are made to Cadastre layers, they may not be reflected in NDMPL.
