    Metadata Updated: May 15, 2024

    The Office of Water Linked Data (OWLD) dataset stores EPA Water program information indexed to several National Hydrography Dataset frameworks. Indexing may be accomplished by catchment, reach or hydrologic unit referencing and includes a curated set of relevant program data attributes. OWLD is closely related to the NHD Event Data model with extensions added to cover catchment-based indexing.
