NOTICE: This geometry of this dataset has been modified by Forsyth County GIS to match the geometry of the county's stream layer. The associated attribute information has not been modified. This ESRI GIS data set is based on the descriptive locations of the listed water bodies within the Year 2008 Integrated 305(b)/303(d) Report, however, it should not be considered as Georgia's approved list. While reasonable effort has been made to ensure this GIS data set accurately reflects the approved list, if discrepancies are found, the water body information in the .pdf documents mentioned below are to be considered official and supercede the GIS data set. On June 6th, 2008, the Georgia DNR Environmental Protection Division's Year 2008 Integrated 305(b)/303(d) Report (also referred to as Water Quality in Georgia 2006-2007) and lists were approved by the United States Environmental Protection Agency's (USEPA). The final and official, approved lists of water body classifications for Rivers/Streams, Lakes/Reservoirs, Coastal Streams, Coastal Beaches, and Sounds/Harbors can be found in .pdf format at https://www.gaepd.com/Documents/305b.html and in the compressed .zip with this GIS data set. This GIS data set represents the State of Georgia assessment of water quality and resulting Year 305(b)/303(d) list of waters prepared in response to Sections 305(b) and 303(d) of the Clean Water Act and in accordance with the USEPA implementing regulations and guidance. Assessed water bodies are classified as assessment pending, supporting or not supporting their designated uses according to a comparison of water quality monitoring results to water quality standards and other pertinent information. New for the Year 305(b)/303(d) list is the designation of Category Tier levels for each assessed water body. The USEPA is requiring Georgia to use these Category Tier levels beginning with year and subsequent 305(b)/303(d) reports to USEPA. Please refer to the .pdf file titled "Summary of Changes to the Format of Y2008 305(b)/303(d) List of Waters" at https://www.gaepd.com/Files_PDF/305b/Y2008_303d/Y2008_Summary_of_Formatting_Changes_List.pdf or in the compressed .zip with this GIS data set for more information about Tier levels. This GIS data set is an ESRI polyline shapefile representing Year 2008 305(b)/303(d) listed Rivers/Streams, Coastal Streams and Coastal Beaches segments at a scale of 1:100,000 in Geographic North American Datum 1983 (NAD83). The majority of the GIS data set is based on previous Georgia EPD GIS shapefiles for the 305(b)/303(d) List for the Years 2006, 2004, 2002 and 2000. Georgia's GIS data set for Year 2008 305(b)/303(d) list has been significantly expanded and improved over previous years GIS shapefiles. All new Rivers/Streams and Coastal Streams segments have been created using the National Hydrography Dataset(NHD) Medium Resolution geodatabase feature class. Beach segments were created by Georgia DNR Coastal Resource Division using aerial photography and color IR DOQQs. When using this GIS dataset, the polylines represent the beginning and end of a listed segment within the state of Georgia. The associated attribute table includes all fields and information within the 305(b)/303(d) list that corresponds to the GIS polyline in addition to USGS Hydrologic Unit Code (HUC) 8 and 10.
