Title:
Great Egg Harbor River Study Area - water-level map (wri914126wlmap)
Abstract:
The four geographic data layers cited here are from the original digital project files of the published hard copy report (Watt and Johnson, 1992) and contain the measured and interpreted water-level data for the unconfined-aquifer system of the Great Egg Harbor River study area. The geographic layers were developed at a scale of 1:24,000, and consist of; (1) the study area boundary (wri914126wlmap_bndry, polygon), (2) water-levels from wells (wri914126wlmap_gwpts, points), (3) water-levels from streams (wri914126wlmap_stmpts, points), and (4) an interpretive water-table contour map (wri914126wlmap_wlcont, lines). The study area encompasses parts of the New Jersey Counties of Atlantic, Camden, and Gloucester, and the entire Great Egg Harbor River basin. The horizontal datum of the data layers is NAD 83, and the vertical datum is NGVD 29. The sheet that contains the water-level information for the Great Egg Harbor River study area represents one part (sheet 2 of 5) of a comprehensive assessment of the hydrology of the unconfined aquifer system study (Watt and Johnson, 1992). The other four sheets of this report are not available in geographic data layer form, but they can be downloaded in PDF format from the complete original report cited herein. The other four sheets comprise information on (1) the hydrogeology and description of the study area, (2) stream discharge and climate data, (3) water quality, and (4) a detailed water-use and water-budget analysis. The digital data sets that support unconfined-aquifer water-levels and interpretations for the Great Egg Harbor River study area are derived from one of nine hard copy published reports which contain similar data and information across other areas of southern New Jersey. Digital data sets for the unconfined-aquifer water-level and interpretive portions from all nine reports are being simultaneously released, motivated by development of an interactive web-viewer tool that enables convenient online viewing of the information (http://nj.usgs.gov/special/web_mapper/). Eight of the nine published reports are from a comprehensive unconfined-aquifer study series; Great Egg Harbor River (Watt and Johnson, 1992), Toms River (Watt and others, 1994), Upper Maurice River (Lacombe and Rosman, 1995), Mullica River (Johnson and Watt, 1996), Salem River (Johnson and Charles, 1997), Maurice River (Charles and others, 2001), Rancocas Creek (Watt and others, 2002), and Atlantic Coastal (Gordon, 2004). The ninth report that contains unconfined-aquifer water-level data and an interpretation is from a comprehensive water-resource study in Cape May County (Spitz, 1998, Lacombe and Carleton, 2002).

Why was the data set created?

The water level information and interpretation presented here provides insight into the depth to water, altitude of the water table, gradient, and direction of groundwater flow within the unconfined aquifer system in the Great Egg Harbor River study area. This study was done in cooperation with the New Jersey Department of Environmental Protection for their purpose of developing information to serve as part of a scientific basis to address environmental, water-resource management and planning, water availability, water use, and water quality questions.
