from 1990 to 1999
 dgs01-2zip (98KB)
N.J. Geological Survey Digital Geodata Series DGS01-2 is a collection of
ten relational data files in a dBASE IV format that document fresh-water
withdrawals in New Jersey by county, HUC11 and HUC14 watersheds, watershed
management areas, and water regions. Data are compiled for calender
year 1999 and for the ten-year period from 1990 to 1999. They are being
made available in a digital format to facilitate water-supply planning and
watershed management in New Jersey. These data summarize fresh-water withdrawal
activities for commercial, industrial, and agricultural users who can produce
more than 100,000 gallons of water a day, and therefore are regulated by
the N.J. Department of Environmental Protection (NJDEP) Bureau of Water
Allocation. The dBASE files are designed to be used in conjunction with a
set of geographic information systems (GIS) polygon coverages available from
the NJDEP GIS. Each file
contains data on withdrawal volumes, sources, and uses and a data field used
for joining these information to the correlative GIS coverages. Metadata
files are included that document each data file using the Federal Geographic
Data Committee metadata standard.
Data are reported for water source and how the water is used, but not where
the water is used. Information on water transfers, discharge activities,
saline-water withdrawals and both depletive and consumptive uses are not
included. More information on the compilation and interpretation of these
data is available from the N.J.Geological Survey Open-File Report OFR 00-1;
New Jersey Water Withdrawals 1990-1996, available from the
NJDEP Maps and
Publications Sales Office.
