Digital Geodata Series
DGS02-5 Selected U.S. Geological Survey and N.J. Department of Environmental Protection Monitoring Networks
Abstract
Digital Geodata Series DGS02-5 is a collection of GIS shape files that show
the locations of selected surface- and ground-water monitoring networks in
New Jersey. The networks are maintained and operated individually or jointly
by the U.S. Geological Survey (USGS) and the N.J. Department of Environmental
Protection (NJDEP). This product does not provide any actual surface-water
or ground-water flow or quality data. The user must contact either the USGS
or NJDEP to obtain observed values.
The USGS maintains a more thorough description of the gages on its website
(http://nj.usgs.gov/).
As locations of additional networks become available in a GIS format they
will be added to this product. Currently available coverages are:
USGS continuous stream-flow gages
USGS stream low flow gages
USGS stream crest gages
USGS continuous tide gages
USGS tidal crest-stage gages
USGS surface-water-quality gages
NJGS/USGS Ambient Ground-Water-Quality Network (AGWQN)
USGS continuous stream-flow gages
The US Geological Survey maintains a network of gages across New Jersey that
continuously monitor stream flows. Funding for these gages comes from both
Federal and State monies. These data are transmitted to the USGS and made
available over the Internet
(http://nj.usgs.gov/).
This coverage provides the locations of these gages. As project needs and
funding levels change, gages may be added or deactivated, and deactivated
sites may be reactivated. The available shape file shows active and inactive
continuous stream gages as of spring 2002.
See the US Geological Survey's web site
(http://nj.usgs.gov/)
for streamflow data. Contact the USGS for more information on these
gages.

USGS stream low flow gages
The US Geological Survey monitors low streamflows at a number of sites across
New Jersey. Funding for these gages comes from both Federal and State
monies. These measurements are made primarily for project work so sites
become active for a few years and then are discontinued.
The data measured at the active sites are published annually as part of the
USGS' series of annual water-data reports.. Contact the USGS for more information
on these gages.

USGS stream crest gages
The US Geological Survey maintains a network of gages across New Jersey that
are periodically monitored to determine stream crest. Funding for these gages
comes from both Federal and State monies. These gages record only the
maximum stream crest between visits. This coverage provides the locations
of these gages. As project needs and funding levels change, gages may be
added or deactivated, and deactivated sites may be reactivated. The available
shape file shows active and inactive continuous stream crest gages as of
spring 2002.
The data measured at the active sites are published annually as part of the
USGS' series of annual water-data reports. Contact the USGS for more
information on these gages.

USGS continuous tide gages
The US Geological Survey maintains a network of gages across New Jersey that
continuously measure tidal levels. Funding for these gages comes from both
Federal and State monies. These data are transmitted to the USGS and
made available over the Internet
(http://nj.usgs.gov/).
This coverage provides the locations of these gages. As project needs and
funding levels change, gages may be added or deactivated, and deactivated
gages may be reactivated. The available shape file shows active and inactive
continuous tide gages as of spring 2002.
See the US Geological Survey's web site
(http://nj.usgs.gov/)
for tide data. Contact the USGS for more information on these gages.

USGS tidal crest-stage gages
The US Geological Survey maintains a network of gages across New Jersey that
are periodically monitored to determine tidal crest-stage. Funding for these
gages comes from both Federal and State monies. These gages record only
the maximum tide crest between visits. This coverage provides the locations
of these gages. As project needs and funding levels change, gages may be
added or deactivated, and deactivated sites may be reactivated. The available
shape file shows active and inactive tidal crest-stage gages as of spring
2002.
The data measured at the active sites are published annually as part of the
USGS' series of annual water-data reports.. Contact the USGS for more
information on these gages.

USGS surface-water-quality gages
The US Geological Survey maintains a network of gages across New Jersey at
which surface water quality is measured. Funding for these gages comes from
both Federal and State monies. This coverage provides the locations
of selected current and historical locations. As project needs and funding
levels change, gages may be added or deactivated, and deactivated sites may
be reactivated. The available shape file shows active and inactive gages
as of spring 2002.
The data measured at the active sites are published annually as part of the
USGS' series of annual water-data reports. Contact the USGS for more
information on these gages.

NJGS/USGS Ambient Ground-Water-Quality Network (AGWQN)
This data set is a GIS point coverage of the NJGS/USGS Ambient
Ground-Water-Quality Network (AGWQN) monitoring wells in New Jersey. This
network is maintained jointly by the New Jersey Geological Survey, NJDEP
and the United States Geolgical Survey. The AGWQN is designed to monitor
the quality of ground water at or near the water table throughout the State.
Shallow ground water is generally the first and most significantly affected
part of the ground-water system, and the quality of this water is directly
related to human activities at the land surface.
The AGWQN is a long-term monitoring network designed to assess the status
of shallow ground-water quality. This is accomplished by 1) examining the
concentrations of various constituents used as environmental indicators,
2) assessing water-quality trends by studying data collected on a 5-year
cycle, 3) investigating the effects of land use on shallow ground water,
4) identifying impacts from nonpoint sources of contamination, and 5) recognizing
from these data emerging or new environmental threats.
The network will consist of 150 shallow ground-water wells throughout New
Jersey within three land-use types. Sixty wells are, or will be, located,
in agricultural areas, 60 in urban/surburban areas, and 30 in undeveloped
areas within New Jersey's five water regions (WR's)- Northwest, Northeast,
Raritan, Lower Delaware, and Atlantic Coastal. Each year approximately 30
wells will be sampled in one or several of the five regions. The cycle of
sampling all 150 wells will be completed every 5 years.
This coverage shows the wells installed in the first three years of the study,
or about 60% of the eventual total. This coverage will be updated as additional
wells are installed.
The data measured at the active sites are published annually as part of the
USGS' series of annual water-data reports.
