Abstract:
The water-table contour map (wri964195wlmap_wlcont, lines) is an interpretation based on water-level measurements that were made specifically for the Salem River study. Measurement sites consisted of strategically selected well and stream and surface water (lakes, ponds) locations. The shape of the water table is controlled principally by topography; therefore the water table contour interpretation tends to be a subdued reflection of the topography. This data layer is the same as that of the ground water-level contour interpretation presented in Johnson and Charles (1997), figure 2-1. The study area includes the entire basins of Salem River, Raccoon Creek, Oldmans Creek, Alloway Creek, and Stow Creek, and parts of the New Jersey counties of Cumberland, Gloucester, and Salem. The horizontal datum of the water-table contour map layer is NAD 83, and the vertical datum is NGVD 29. The water-table contour map is one of four data layers used to present the water-level information for the Salem 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 (wri964195wlmap_bndry, polygon), (2) water-levels from wells (wri964195wlmap_gwpts, points), (3) water-levels from streams (wri964195wlmap_stmpts, points), and (4) an interpretive water-table contour map (wri964195wlmap_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 Salem 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 Salem 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-table contour map for the Salem River study area consists of interpreted lines of equal water-table altitude, based on water levels measured in wells and streams. 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.
