This data set consists of geo-referenced digital data and associated attributes created in accordance with the "FGDC Proposal, Version 1.0 - Federal Standards For Delineation of Hydrologic Unit Boundaries 3/01/02" http://datagateway.nrcs.usda.gov/ Polygons are attributed with hydrologic unit codes for 4th level sub-basins, 5th level watersheds, 6th level subwatersheds, name, size, downstream hydrologic unit, type of watershed, non-contributing areas and flow modification. Arcs are attributed with the highest hydrologic unit code for each watershed, linesource and a metadata reference file Purpose: The Watershed and Subwatershed hydrologic unit boundaries provide a uniquely identified and uniform method of subdividing large drainage areas. The smaller sized 6th level sub-watersheds are useful for numerous application programs supported by a variety of local, State, and Federal Agencies. This data set is intended to be used as a tool for water-resource management and planning activities, particularly for site-specific and localized studies requiring a level of detail provided by large-scale map information. The dataset will be appended to a larger seamless nationally consistent geospatial database as other states complete their portion of the watershed boundary dataset.

Native_Data_Set_Environment: Microsoft Windows 2000 Version 5.1 (Build 2600) Service Pack 1; ESRI ArcCatalog 8.3.0.800 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: All HUC12 boundaries were visually compared to the elevation contours and water courses to ensure watershed boundaries followed ridges and grouped water courses into logical groupings. Logical_Consistency_Report: 100% of the attributes were visually verified using 24K digital raster graphics (DRG's). The accuracy of this data is dependent on the level of detail of the source material and the interpretation procedures for capturing that source. Completeness_Report: The current HUC14 coverage is a more detailed representation of the watersheds and should nest conformably within the HUC12 coverage. However, the current (2008) HUC12s were drawn based on less precise hydrography. The current HUC14s have numerous sliver problems and do not match exactly the HUC12 boundaries on the boundaries between watersheds. It is anticipated that in the near future a much more accurate elevational dataset will be prepared using LIDAR. This will lead to a much more accurate set of HUC14 watershed boundaries. Once this is completed new HUC12s will be created. For Completeness Report, guidelines state the following: All fields for all polygons in the .pat are attributed. Some polygons in the Ncontrb_a field might have a 0 value. All fields for the lines in the .aat are attributed. The lines adjacent to the universal polygon are attributed with a 0 for the hu_level. These cannot be attributed until the adjacent states complete their linework at which point the highest level of hydrologic unit can be determined. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The New Jersey WBD was produced using Digital Raster Graphics (DRG's) as the source map. Data completeness for DRG files reflects content of the source graphic and may therefore be reflected in the completeness and accuracy of the WBD. The map was digitized from USGS 1:24,000-scale digital raster graphic base maps, with an inherited error of +/- 40 feet according to the USGS National Map Accuracy Standards. It is estimated that any errors detected were less than 10%. It should also be noted that while general rules of hydrology were used (i.e. natural water flow is downhill), the locations of boundaries is still somewhat subjective as the 1:24,000-scale DRG's do not always provide enough information for identifying the location of the boundaries.

Drainage basins are delineated from 1:24,000-scale (7.5-minute) USGS quadrangles. The delineations have been developed for general purpose use by USGS District staff over the past 20 years. Arc and polygon attributes have been included in the coverage with basin names and ranks of divides, and 14-digit hydrologic unit codes. The New Jersey state boundary as originally defined in the USGS source coverage does not match that used by the NJDEP. Therefore the coverage was edited by the NJ Geological Survey to remove the USGS state boundary and insert the NJDEP state boundary, thus resolving most potential clipping errors. During the process of creating the HCU12s a number of errors were revealed in the HUC14 boundary dataset. These HUC14 errors are in the process of being corrected and an updated GIS coverage is anticipated to be ready in 2009. Process_Step: Process_Description: The NJ-WBD dataset was created via on-screen (heads-up) digitizing methods by contractors employed by the Environmental Protection Agency Region3 office using digital raster graphics (DRG's) as base maps. Following the development guidelines identified in the Federal Standards for Delineation of Hydrologic Unit Boundaries (V2.0, October 1, 2004), Subbasins (8-digit units) were subdivided into 40,000 - 250,000 acre sized Watersheds (10-digit units) and 10,000 - 40,000 acre sized Subwatersheds (12-digit units). If a hydrologic unit fell above or below these acreage levels, it was evaluated to determine its need for inclusion in the dataset. Hydrologic units above the threshold level were normally a frontal or coastal area identifying a mixture of upland and open water drainage, or simply an open-water hydrologic unit. In few instances, an upland hydrologic unit was maintained at an acreage total below 10,000 acres for subwatersheds. This was acc! eptable if no other practical or logical subdivision of that hydrologic unit was apparent or if merging the smaller hydrologic unit with a neighboring hydrologic unit would negatively influence (one of) the dataset's objectives of identifying uniquely named hydrologic units. Process_Date: 2008 Process_Step: Process_Description: Hydrologic units from Pennsylvania, New York and Delaware were used to edgematch watershed boundaries. Process_Date: 2008 Process_Step: Process_Description: The NJ-WBD dataset was submitted to the NJ-DEP (summary reports and review methodology exercised by NJ) Process_Date: 2008 Process_Step: Process_Description: Data projected to NJ State Plane Feet, NAD83. After the NJ-DEP reviewed this dataset, it was returned to the EPA R3 office where edits were made prior to the dataset being submitted for final review by coordinators for the National Watershed Boundary Delineation Project.

Attribute_Definition_Source: Federal Standards for Delineation of Hydrologic Unit Boundaries Attribute_Domain_Values: Unrepresentable_Domain: unique Overview_Description: Entity_and_Attribute_Overview: This is a description of attributes by field from the Federal Standards for Delineation of Hydrologic Unit Boundaries 1) Polygon attributes Huc_8 : Eight Digit Hydrologic Unit Code A unique 8-digit code from the USGS map series "Hydrologic Unit Maps". The same number was used in every record that pertains to a subwatershed that resides within the same 8-digit sub-basin.Numbers were assigned in an upstream to downstream fashion. Where no downstream/upstream relationship could be determined numbers were assigned in a clockwise fashion. Huc_10: Ten Digit Hydrologic Unit Code This field provides a unique 10-digit code for each watershed. This same number was used in every record that pertains to a subwatershed that resides within the same 10-digit watershed. Numbers were assigned in an upstream to downstream fashion. Where no downstream/upstream relationship could be determined numbers were assigned in a clockwise fashion. Huc_12: Twelve Digit Hydrologic Unit Code This field provides a unique 12-digit code for each subwatershed. Numbers were assigned in an upstream to downstream fashion. Where no downstream/upstream relationship could be determined numbers were assigned in a clockwise fashion. Acres: Acres Area of subwatershed including non-contributing areas calculated to acres as a whole number, no decimals. The "Acres" field was calculated from the "Area" field. States: States The "States" field includes the names of all state(s) that the subwatershed falls within. The 2-digit postal abbreviation in upper case and in alphabetical order was used, separated with a comma. Ncontrb_a: Non-Contributing Area Drainage areas that do not flow toward the outlet of any hydrologic unit are considered non-contributing. If a non-contributing area is on the boundary between two or more hydrologic units, the non-contributing area is associated with the hydrologic unit adjacent to the low point on the boundary. This attribute should be the total of the non-contributing areas within a hydrologic unit calculated in acres. Hu_10_ds: Fifth Level Downstream Hydrologic Unit Code This field has the 10-digit code of the 5th level hydrologic unit that is receiving the majority of the flow from the watershed that the 6th level HU falls within. Outlets created by ditching or other artificial drainage were not considered for this field. If an HU flows into an ocean or the Gulf of Mexico, this field was populated with "OCEAN" and if a HU flows into one of the Great Lakes the term "LAKE" was used. If a HU flows across international borders, "CANADA" or "MEXICO" was used depending on which country the HU drains into. If an HU is a closed basin, then the term "CLOSED BASIN"was used. Hu_10_name: Fifth Level Hydrologic Unit Name This field used officially recognized names only.
