“…An existing border waters GIS layer was used as a starting point to perform additional NHDPlus navigation procedures to ensure the selection of appropriate immediate border water flowlines in the current version of the NHDPlus used in the RAD. The NHD upstream and downstream navigation procedures (Cooter et al 2000;Spoerri et al 2000;Ilieve et al 2001) have been incorporated in a series of NHD tools that can be downloaded along with complete documentation from the USGS NHD website (USGS 2009c). The NHDPlus also incorporates most of the names from the USGS Geographic Names Information System (GNIS), a database that holds the federally recognized named water features and defines the location of these features by state, county, USGS topographic map, and geographic coordinates (USGS 2009d).…”

A 1988 survey, funded by the US Environmental Protection Agency (EPA) and conducted by the American Fisheries Society, identified the need to standardize the approaches for evaluating risks and developing fish consumption advisories that are comparable across different jurisdictions. A major tool for evaluating the progress in developing such nationally consistent information is EPA's web-based National Listing of Fish Advisories (NLFA) database, which has archived fish advisory information since 1993. The NLFA comprises both a database and Geographic Information System mapping components that are implemented using the National Hydrography Dataset (NHD). EPA and the US Geological Survey have developed an enhanced NHD product (NHDPlus) that is applied to define an interstate waters framework for the conterminous USA. This NHDPlus-based framework provides an efficient watershed-oriented approach for identifying interstate advisories from NLFA. We provide summaries of (1) the degree of consistency documented for inland waters where states have issued advisories for shared interstate NHD reaches and (2) the patterns for interstate advisories organized according to the ecoregions developed for EPA's Wadeable Streams Assessment. Approaches are also discussed for addressing interstate consistency issues for fish advisories in coastal waters making use of the NHDPlus combined with other nationally consistent frameworks, such as the 12-digit hydrologic unit code subwatersheds in the Watershed Boundary Dataset. Probability survey methods are recommended as a way to promote increased interjurisdictional consistency in the development of the monitoring and risk assessment conclusions reflected in NLFA, as well as in other EPA water quality-based programs.

The US Environmental Protection Agency's (EPA's) Total Maximum Daily Loads (TMDL) program promotes nationally consistent approaches for documenting the progress in restoring impaired waters. EPA's TMDL program provides tracking systems comprising both database and geographic information systems (GIS) mapping components. The GIS mapping is implemented using the National Hydrography Dataset (NHD). The EPA and the US Geological Survey have developed an enhanced NHD product (NHDPlus) that is applied in this study to define an interstate waters framework for the conterminous United States. This NHDPlus-based framework provides an efficient watershed-oriented approach for selecting interstate waters. Greater consistency in approaches for interstate waters is essential for providing improved techniques for integrated assessment and management programs. Improved analysis tools for interstate waters are clearly important from a federal perspective. Insights based on tools for federal interstate waters are also of interest for state water quality agencies when they deal with complicated interjurisdictional challenges that can require leveraging support from a wide range of stakeholders. Summaries are provided on the degree of consistency documented for inland waters where states have provided TMDL listing GIS information for shared interstate NHD reaches, and summaries are provided on the patterns for interstate assessments organized according to the ecoregions developed for EPA's Wadeable Streams Assessment. The relevance of this interstate waters framework in leveraging the TMDL program to provide enhanced support for watershed oriented management approaches is also explored.
