Note: Some information in this metadata describes the DEPHUC 14 coverage instead of the DEPHUC 11 because DEPHUC 14 is more detailed. Most processes and procedures used are identical for both coverages.

2. NJGS Processing Notes for Dephuc14
12/22/99 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. The coverage was built as a polygon and line coverage.
12/28/99 The new coverage was edited to delete the USGS version of the NJ State boundary, then equivalent lines from the NJDEP State-boundary reference coverage (stateco) were added in their place. All node errors and label errors were edited, then the coverage was dissolved from a sub-huc14 level to the huc14 level.
12/30/99 The dephuc14 coverage was cleaned, then polygon labels from an earlier version were joined to the PAT in order to preserve NJPDES attributes for unchanged polygons. Watershed Management Area, Water Region, and new HUC codes were edited to reflect the revisions. Repeated PAT items were dropped.
01/03/00 The dephuc14 AAT was edited to add USGS and NJGS field items HUCDIV and LINTYPE respectively. HUCDIV is an item used to represent the HUC4, HUC6, HUC8, HUC11, and HUC14 boundary lines, with the lower HUC values taking precedence over higher values. LINTYPE denotes those lines taken from the NJ State boundary theme (LINTYPE 9).
01/26/00 Arc attributes were manually updated to reflect HUC and LINTYPE values. The coverage was then rebuilt.
02/04/00 Arcs were added and deleted from the coverage based on NJDPES review to correct HUC14 basin delineation.
02/10/00 ARCS were added to coverage based on NJPDES review and USGS agreement to correct HUC14 basin delineation. All HUCDIV arcs items and HUC14 polygon items updated and checked. The set of 212 NAD83 quadrangle tics for the State were added to dephuc14 to replace the set of four tics originally included in the coverage. The dephuc14 coverage was cleaned and duplicated as dephuc14bup.
03/17/00 Created two new HUC14 polygons by adding two new lines based on NJPDES review of proposed changes with the USGS. Recleaned the coverage.
03/20/00 Updated coverage polygon labels with NJPDES labels. Added HUC4, HUC6, HUC8, WREGION, WR-NAME, WMA_NAME and WMNAME items and updated them to DWM specifications.
03/27/00 Added a new HUC11 line to split offshore HUC11 02040302910 in order to add 02040302920. Updated HUCDIV lintypes for altered area. Update HUC14 d_swid codes for 4 polygons. Dissolved dephuc14 into dephuc11, added and updated .PAT items for WMA, WMA_NAME, WREGION, and WR_NAME.
9/11/00 Calculated total drainage area of each subwatershed. This includes area that drains to the subwatershed plus that of the subwatershed. Expressed area in acres and square miles. Added areas to coverage.
