Great Lakes Geographic Information System U.S. Environmental Protection Agency 20061213 Ann Arbor, MI Great Lakes Information Network (GLIN) http://gis.glin.net/ogc/services.php#lmb_rad303d_area_epa River segments, lakes, and estuaries designated under Section 303(d) of the Clean Water Act. Each State will establish Total Maximum Daily Loads (TMDLs) for these waters. Most Current 303(d) Waterbodies coded onto NHD Waterbody reaches (region.rch) to create Waterbody Shapefiles. To be used to identify the spatial extent of waters listed under §303(d). These waters can be linked to the Most Current §303(d) information stored in the EPA TMDL Tracking System for query and display. The ENTITY_ID field in the waterbody shapefile can be linked to the LIST_ID in the EPA's TMDL tracking system. This join has already been completed in these 303d files. For a complete rendition of the 303d waterbodies the point, line and area shapefiles all need to be combined.

Research Triangle Institute (RTI), under contract with EPA, georeferenced (or indexed) states' impaired waters to the National Hydrography Dataset (NHD). EPA would like each state to have the opportunity to review the indexing work. Reviewers are asked to assess the accuracy of WQS reach indexing (georeferencing) efforts. More specifically, reviewers are asked to evaluate whether designated uses are assigned to the appropriate reaches and to assess the accuracy of the locational information.
