The 303(d) Listed Impaired Waters program system provides impaired water data and impaired water features reflecting 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. Note the CWA Section 303(d) list of impaired waters does not represent waters that are impaired but have an EPA-approved TMDL established, impaired waters for which other pollution control mechanisms are in place and expected to attain water quality standards, or waters impaired as a result of pollution and is not caused by a pollutant; therefore, the "Impaired Waters" layers do not represent all impaired waters reported in a state's...
The dataset represents hydrological features, extracted from the NHDPlus NHDWaterbody shapefile, that intersect a 1 mile interior coastline buffer along the Gulf of Mexico and Atlantic Ocean coasts within our study area, from Texas to New Jersey. The NHDPlus NHDWaterbody shapefile describes NHD polygonal features of types: Playa, Ice Mass, LakePond, Reservoir, SwampMarsh, and Estuary. NHDPlus is a complex, nationwide dataset features that can be accessed here (last checked 06/16/10): http://www.horizon-systems.com/nhdplus/ . Its original metadata is included below. The NHDPlus Version 1.0 is an integrated suite of application-ready geospatial data sets that incorporate many of the best features of the National...
The dataset represents hydrological features, extracted from the NHDPlus NHDArea shapefile, that intersect a 1 mile interior coastline buffer along the Gulf of Mexico and Atlantic Ocean coasts within our study area, from Texas to New Jersey. The NHDPlus NHDArea shapefile describes NHD polygonal features of types: Area to be Submerged, BayInlet, Bridge, CanalDitch, DamWeir, Flume, Foreshore, Hazard Zone, Lock Chamber, Inundation Area, Rapids, SeaOcean, Special Use Zone, Spillway, StreamRiver, Submerged Stream, Wash, Water IntakeOutflow, and Area of Complex Channels.

This is the flowline feature in the NHD plus dataset for region 18. For full attribute definition, consult the NHD plus user guide. TNC joined the attributes from the tbl_nhd_flowlineattributesflow table in the geodatabase to get all of the relevant attributes. The NHDPlus Version 1.0 is an integrated suite of application-ready geospatial data sets that incorporate many of the best features of the National Hydrography Dataset (NHD) and the National Elevation Dataset (NED). The NHDPlus includes a stream network (based on the 1:100,000-scale NHD), improved networking, naming, and "value-added attributes" (VAA's). NHDPlus also includes elevation-derived catchments (drainage areas) produced using a drainage enforcement...
This is the flowline feature in the NHD plus dataset for region 18 with just the streams and rivers designated as perrenial. For full attribute definition, consult the NHD plus user guide.
