Geometry Type: esriGeometryPolyline

Description: Provide assessment summary details for all riverine waters identified within the 2024 305(b)/303(d) Water Quality Assessment Integrated Report. The Assessment Unit (AU) dataset was created from United States Geological Survey (USGS) National Hydrography Dataset (NHD) high-resolution 1:24,000 data extracted in September 2012. The NHD product was used by DEQ regional assessment staff to assign previously established assessment unit IDs based on predetermined up- and downstream extents and applicable Water Quality Standards. Some erroneous waters were removed and a few waters were updated using Virginia Base Mapping Program aerial photography from Virginia Geographic Information Network (VGIN), and recent NHD data where available.
