Aquatic Pesticides 2007 - aquapest.zip (0.13 MB, 2.64 MB unzipped)
The 2007 Aquatic Pesticides Sites List for New Jersey are those sites that were permitted through the NJDEP Pesticide Control Program for aquatic pesticide use
in the waterbodies of the state. Site location names are provided by pesticide applicators, and may differ from state/county/municipality recognized names. Point
locations do not indicate area of pesticide usage, only indicate the waterbody/aquatic site where treatment was permitted. Sites with multiple waterbodies under
one permit have just one point location, usually at the waterbody closest to the outlet/receiving water source. There were a total of 1108 permit applications
submitted to the department in 2007, however only 1080 sites are included in this dataset. Thirteen applications were withdrawn or denied, 11 were special local
needs permits for natural bottom swimming pools, and 4 permits were for right-of-way maintenance and could not be expressed by a single point. These sites were
intentionally removed. If there are questions about specific sites please refer to listed responsible NJDEP contacts. This data was compiled and manipulated for

"poor", "fair", "good" or "excellent".
Golf Courses (Statewide) - njgolf.zip (615 KB, 1495 KB unzipped)
This data represents the fairway, green and tee areas of all the golf courses in New
Jersey. It was created by selecting all recreation polygons from the 1995/97 NJDEP land
use/land cover (LU/LC) file. There are 256 courses identified and 553 polygons (Many
courses show as discontinuous polygons because fairways/green/tee zones are separated
by tracts of wetland, forest or other land covers. The purpose of the file is to determine
course acreage to assist in estimating the amount of pesticide, fertilizer, and herbicide
used on an annual basis. Therefore substantial (1 acre or more) tracts of forest or
wetlands are not included in a course's polygons, although these areas may be owned by
the Golf Course.
Head of Tide (hot) - hot.zip (30 KB, 121 KB unzipped)
This is a graphical representation of the head of tide (hot) points for
watercourses of New Jersey. This includes the tributaries of these watercourses as well.

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 (2.53 MB, 5.51 MB unzipped)
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.
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
Watersheds (Watersheds by name - DEPHUC11) - dephuc11.zip (995 KB, 2441 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.
