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.

The Tidelands claims line depicts areas now or formerly flowed at or below mean high tide. Since the mean high water line may change because of rises in sea level, the line does not represent the current mean high water line. Rather it depicts the mean high water line at the time of mapping and the historic mean high water line predating artificial alterations.

Tidelands Grid - tidegrid.zip (103 KB, 434 KB unzipped)

This dataset is a graphical representation of riparian tidelands grid for New Jersey's Atlantic Coast. It was automated at a scale of 1:24000. Coverage was partially attributed by IEP and the BGIA and Tidelands completed the coding and checked the codes.

Total Maximum Daily Loads (TMDLs) for Eutrophication Lakes - tmdl_lakes.zip (107 KB, 327 KB unzipped)

The pollutant of concern for the Eutrophic Lake TMDLs is phosphorus. Phosphorus is an essential nutrient for plants and algae, but is considered a pollutant when it stimulates excessive plant and algae growth. Overgrown vegetation and algae blooms in lakes can prevent recreational use for fishing and swimming. In severe cases, plant and algae die-off can deplete oxygen in the lake raising the potential for killing fish in the lake.

Total Maximum Daily Loads (TMDLs) for Fecal Streams - tmdl_streams.zip (275 KB, 930 KB unzipped)

The pollutant of concern for these Stream TMDLs is pathogens, the presence of which is indicated by elevated concentrations of fecal coliform bacteria.

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.

Watershed Management Areas - depwmas.zip (373 KB, 898 KB unzipped)

The depwmas data is a simplified version of the ARC/INFO 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.
