Description:
Abstract:
The 14-digit hydrologic units (HUC14s) in New Jersey is a revision of the 2006 version of these units. This version corrects some boundaries to be consistent with a new hydrography coverage based on 1:2,400 aerial photographs (NJDEP, 2008). It also makes some changes to be more consistent with a new 12-digit hydrologic unit coverage (EPA, 2009). This editing process created 42 new HUC14s, deleted one inland HUC14 and five coastal HUC14s in the Delaware Bay, and changed over 100 boundaries. A report detailing these changes (Hoffman and Pallis, 2009) is available online . For programmatic reasons the 14-digit units are clipped to New Jersey's political boundary.
HUC14 hydrologic units were first published by Ellis and Price (1995) and made available as a shape file by the New Jersey Department of Environmental Protection soon afterword. Watershed boundaries were based on elevations and water courses from 1:24,000-scale (7.5-minute) USGS quadrangles. These were revised (NJDEP, 2006) by clipping the unit boundaries to the official NJ state boundary and addition of some additional identification information. Some boundaries were changed at that time to reflect errors found in the original coverage.
This product is an interim product and will be replaced once better elevational data are available. It is based on elevational data from quadrangle maps at a scale of 1:24,000. The hydrography is at 1:2,400. Once high-resolution LiDAR data (at 1:2,400 or better) become available for New Jersey the 14-digit hydrologic units will be redrawn and this interim coverage will be replaced.
EPA's 12-digit hydrologic system (USEPA, 2009) uses a numbering convention that is not entirely consistent with the 14-digit numbering system. For some HUC14s, the first 12 digits do not match the identification number of the 12-digit hydrologic unit it lies within. These discrepancies will be corrected when the HUC14s are next revised.
Purpose:
This coverage defines hydrologic units for New Jersey. It is designed to identify the area which drains to a point of interest. It can be used as a starting point to delineate a study area with a drainage basin boundary.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attributes were verified against various sources, including USGS huc14 coverage and NJPDES data.
Logical_Consistency_Report:
The dephuc14 has been reassembled from the USGS HUC14 coverage (which was based on 1:24,000 hydrography and elevational data), clipped to the NJ state boundary, and then revised based on a new 1:2,400 hydrography. This data is not field checked and has no guarantees as to its accuracy.
EPA's 12-digit hydrologic system (USEPA, 2009) uses a numbering convention that is not entirely consistent with the 14-digit numbering system. For some HUC14s, the first 12 digits do not match the identification number of the 12-digit hydrologic unit it lies within. These discrepancies will be corrected when the HUC14s are next revised.
Completeness_Report:
The project as originally designed has been completed for the entire state. The hydrologic unit boundaries are clipped to the NJ State political boundary. Thus those units that extend across the New Jersey-New York boundary are not accurately displayed.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
As part of the original processing (NJDEP, 2006) NJGS received sub-huc14 basins coverage from USGS-WRD in NAD27 UTM coordinates and began processing into Dephuc14 in NAD83 State Plane Feet coordinates. Projection resulted in a coverage that was shifted about 735 ft SSW in comparison to earlier coverages. The reason for, and origin of this shift is unknown. Therefore, the projected coverage was manually transformed using an affine transformation to best fit the correct line positions based on a comparison to earlier version of the dephuc14 coverage.

Process_Description:
14-digit hydrologic units that are revised from an earlier version (NJDEP, 2006). This revision process is based on more accurate hydrography (NJDEP, 2008) and a better delineation of drainage areas. This process created 42 new HUC14s, deleted one inland HUC14 and five in the Delaware Bay, and changed over 100 boundaries. A full description of these change is in Hoffman and Pallis (2009) available online at <http://www.njgeology.org/pricelst/tmemo/tm09-2.pdf>.
After all edits were made the areas were updated in the ArcGIS environment.
