Abstract:
The water-levels from streams data (wri914126wlmap_stmpts, points) includes stream and surface water (lakes, ponds) level measurements that were made specifically for the Great Egg Harbor River study, using a set of strategically selected locations that, along with water-levels from wells, provided control for construction of an interpretive water-table contour map. Water-level measurements were selected where a culvert, bridge, or concrete berm provided ready accessibility and a reference point, and especially where there was a lack of other water-level control points. In upstream areas, an effort was made to bracket measurement points between a dry point and a flowing point, thus indicating a stream interval in which start-of-flow can be inferred. All stream and surface-water-level measurement sites were entered into the project database. This data layer is the same as the stream-water-level data and interpretation presented in Watt and Johnson (1992), figure 2.1. The study area encompasses all of Great Egg Harbor River basin and parts of the New Jersey Counties of Atlantic, Camden, and Gloucester. The horizontal datum of the water-levels from streams data layer is NAD 83, and the vertical datum is NGVD 29. The water-levels from streams data is one of four data layers used to present the water-level information for the Great Egg Harbor River study area. The four geographic data 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 water-level information represents one part (sheet 2 of 5) of a comprehensive assessment of the hydrology of the unconfined aquifer system in the Great Egg Harbor River study area. 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 (Lacombe and Carleton, 2002).
Purpose:
The water-levels from streams data for the Great Egg Harbor River study includes stream and surface water levels, and related site information that were compiled, along with water levels measured in wells, to construct a water-table contour map. The water-table contour map can be used to provide an interpretive assessment of depth to water, water-table altitude, water-table gradients, and the direction of groundwater flow within the unconfined aquifer system. The study was performed in cooperation with the New Jersey Department of Environmental Protection for their purpose of developing a scientific basis to help address environmental, water-resource management and planning, water availability, water use, and water quality questions.
