A WQMP is used in conjunction with the Statewide WQM Plan, which together constitute the Continuing Planning Process conducted pursuant to the WQPA, the Water Pollution Control Act, N.J.S.A. 58:10A-1 et seq., and N.J.S.A. 13:1D-1 et seq., and as required by Sections 303(e) and 208 of the Federal Clean Water Act (33 U.S.C. 1251 et seq.) to make consistency determinations under the Water Quality Management (WQM) Planning rules, N.J.A.C. 7:15.

Water Quality Stations (Existing) - ewqpoi.zip (39 KB, 181 KB unzipped)

This data represents sampling points for the EWQ (Existing Water Quality) project at NJDEP. The EWQ Network was designed to provide supplemental data for water quality for the entire state.

Water Supply Planning Areas - wsplarea23.zip (399 KB, 959 KB unzipped)

This data provides a spatial delineation of the 23 Water Supply Planning Areas as depicted in the New Jersey Statewide Water Supply Plan (NJSWSP). The NJDEP's Office of Natural Resource Restoration uses the data to spatially reference ground water contaminant plumes at contaminated sites, in-order to determine if a contaminant plume is within a "Surplus" or "Deficit" water supply planning area. This information is used in ground water injury calculations.

Waterbodies (Lakes & Ponds) - njwaterbody.zip (13.8 MB, 32.0 MB unzipped)

The data was created by extracting water polygons which represented lakes and ponds from the 2002 land use/land cover (LU/LC) layer from NJ DEP's geographical information systems (GIS) database.

Waterbodies (Rivers, Bays & Oceans) - njarea.zip (25.3 MB, 93.3 MB unzipped)

The data was created by extracting water polygons which represented Rivers, Bays and Oceans from the 2002 land use/land cover (LU/LC) layer from NJ DEP's geographical information systems (GIS) database.

Watershed Management Areas - depwmas.zip (.43 MB, .87 MB unzipped)

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.

Watersheds (Subwatersheds by name - DEPHUC14) - dephuc14.zip (2210 KB, 5595 KB unzipped)

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.

Watersheds (Subwatersheds by name - DEPHUC12) - dephuc12_boundary.zip (3.66 MB, 4.88 MB unzipped)

This data set is a digital hydrologic unit boundary layer (clipped at New Jersey political boundaries) to the Subwatershed (12-digit) 6th level for the State of New Jersey. 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

Well Program Atlas Sheet Grid - atlasgrid.zip (12.08 MB, 41.23 MB unzipped)

This grid is based on an old map series called the New Jersey Atlas Sheets and on a reference system based on them called the New Jersey Rectangular Coordinate System. The grid system developed as the ATLAS_GRID does not exist on the atlas sheets but is based on latitide and longitude grids included on the sheets.

Wind Turbine Siting Map (Large Scale) - windturbinesiting.zip (9.73 MB, 15.41 MB unzipped)

ADVISORY: This layer depicts land areas in the coastal zone where large scale wind turbines are unacceptable due to the operational impacts of turbines on birds and bats.

Upper Wetlands Boundary/Upper Wetlands Limit - uwb_uwl.zip (3.04 MB, 9.36 MB unzipped)

Upper Wetlands Boundary/Upper Wetlands Limit data layer is composed of two wetlands limit lines mapped in two separate NJDEP mapping programs.
