Description:

Abstract:: The depwmas data is a simplified version of dephuc14 data. The dephuc14 is NJDEP's version of the U.S. Geological Survey (USGS) hydrologic-unit-code basins that delineates the extent of the DEP watershed management regions and areas to be used for the statewide watershed initiative. Both the depwmas and dephuc14 data comprise the Watershed Base Maps for New Jersey. Also, both were created from the USGS HUC14 by replacing the state boundary included with the USGS version with the DEP state and county border data(stco). The data was produced to address data-processing problems arising from combining the USGS huc14 with NJDEP GIS data due to the use of conflicting state boundaries.
Purpose:: Polygon and line coverage of watershed regions and watershed management areas (WMAS) proposed by the NJDEP for watershed characterization and assessment. Includes an polygon item field for the names of the WMAS and line item filed for State and WMA boundaries.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: Depwmas was produced by reselecting and labeling arcs corresponding to the proposed NJDEP watershed management area and regions from the dephuc14 coverage. Polygon label were added and attributed accordingly.

Logical_Consistency_Report:

The dephuc14 and depwmas are polygon and line coverages reassembled from the USGS HUC14 coverage. The HUC14 hydrologic unit boundaries, not including the state boundary, were delineated by the USGS from 1:24000 scale (7.5 minute) USGS topoquads. These data have been checked and verified by the NJDEP. Refer to huc14 metadata for more information regarding the data source. The state boundary lines included in these coverages are from the NJDEP digital data set stco. Refer to stco metadata for the origin and accuracy of these lines.

Completeness_Report: Updated 200403

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: From the Horizontal Positional Accuracy Report for dephuc14, the parent coverage: 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 an 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_Step:

Process_Description:: This data layer and the data layer from which depwmas was derived (dephuc14) are polygon and line coverages reassembled from the USGS HUC14 coverage. The HUC14 hydrologic unit boundaries, not including the state boundary, were delineated by the USGS from 1:24000 scale (7.5 minute) USGS topoquads. These data have been checked and verified by the NJDEP. Please refer to huc14 metadata for more information regarding the data source. The state boundary lines included in these coverages are from the NJDEP digital data set stco. Please refer to stco metadata for the origin and accuracy of these lines.
Off of New Jersey's Atlantic Ocean boundary the WMA boundaries (for WMAs# 12, 13, 14, 15, and 16) are set at 3 statue miles where a statue mile is 5,280 feet. This is not equivalent to the New Jersey state boundary. New Jersey's state boundary on the Atlantic Coast is 3 geographical miles offshore where 1 geographical mile is 6,087 feet. This is established by the 1953 Federal Submerged Lands Act.
DATA AUTOMATION AND ACCURACY
Depwmas was produced by reselecting and labeling arcs corresponding to the proposed NJDEP watershed management area and regions from the dephuc14 coverage. Polygon labels were added and labeled accordingly.

Process_Date: 200403

Process_Step:

Process_Description:: The Division of Watershed Management, in working with the various local watershed partners determined that the issues in Bayonne and the portion of Jersey City which were located within WMA 7 had more in common with WMA 5 then WMA 7. Therefore, the boundaries of WMA 5 and 7 were adjusted to move Bayonne and the portions of Jersey City that were in WMA 7 to WMA 5.
