In August 2010, NJDEP completed the statewide attribute transfer of the USGS 1:24000 high-resolution National Hydrography
Dataset (NHD) to the 2002 Waterbody and Stream Network data layers. This data is a subset of the complete NHD geodatabase
and includes only features within New Jersey borders. The NHDWaterbody2002 layer combines NHDArea and NHDWaterbody feature
classes. The NHDStreams2002 includes only the NHDFlowline feature class for New Jersey. This stream data layer replaces the
previous version as of January 2011. It is provided here in ESRI 9.2 File Geodatabase format with the geometric network,
which can be used with the Utility Network Analyst toolbar.
NJDEP/BGIS is committed to the Stewardship and maintenance of the USGS National Hydrography Dataset. Periodic edits by NJDEP
and surrounding states are conducted and may not be included in this layer. For the most current data visit the USGS NHD website
http://nhd.usgs.gov/data.html and download the
complete dataset by subbasin using the NHDViewer.
This data contains NHD compliant attributes including COMIDs and REACHCODEs. GNIS_ID, GNIS_NAME, FTYPE, and FCODE attributes are NHD
compliant and were transferred from the NHD data layers. Officially recognized stream names have a GNIS_ID. All "unnamed tributaries"
flowing into a named watercourse have the "tributary" extension. Sources of names include Surface Water Quality Standards layer, USGS NHDgeo NHDFlowline feature class, and earlier Hydrography layers. Discrepancies exist between these layers as well as published USGS topographic maps. These will be evaluated and corrected in later versions.
The shape files are for display and query only
