This web service is a subset for New York State of the <\/span>UGSS 3D Hydrography Program (3DHP)<\/span><\/a> with improvements started by New York State Geospatial Services. The most recent 2026 3DHP data was <\/span>downloaded<\/span><\/a> and data was reduced to data that intersected New York State. <\/span><\/p>

<\/p>

NYS Geospatial Services has begun improving data within 8 digit HUCs within the state. We prioritize areas to improved base around current plans for USGS 3DHP. Improvements within a HUC include reviewing all waterbodies to ensure they are still valid and spatially accurate. Where existing hydro-breaklines exist, we replace and/or add existing waterbodies with the newer geometry and append attributes were applicable. Currently the following HUCs have been updated: Hudson-Hoosic (02020003).<\/span><\/p>
