Abstract:
The water-level from streams data (wri014246wlmap_gwpts, points) includes stream and surface water (lakes, ponds) level measurements that were made specifically for the Cape May 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 Spitz (1998), and Lacombe and Carleton (2002). The study area includes part of Tuckahoe River Basin, and includes but is not limited to the entire basins of Tarkiln Brook, Mill Creek, Fishing Creek, Dias Creek, Bidwell Creek, Goshen Creek, Dennis Creek, Sluice Creek, East Creek, and West Creek, and all of Cape May County, New Jersey, and parts of the New Jersey Counties of Atlantic and Cumberland. 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 Cape May study area. The four geographic data layers were developed at a scale of 1:24,000, and consist of; (1) the study area boundary (wri014246wlmap_bndry, polygon), (2) water-levels from wells (wri014246wlmap_gwpts, points), (3) water-levels from streams (wri014246wlmap_stmpts, points), and (4) an interpretive water-table contour map (wri014246wlmap_wlcont, lines). The water-level information for the unconfined aquifer system in the Cape May study area presented here is drawn from two reports of much larger scope, that include an assessment of the hydrogeologic framework, groundwater flow, availability of water supplies and salt-water intrusion. The information from the rest of the original reports are not available in geographic data layer form, but can be downloaded as PDF's of the complete original reports cited herein. The digital data sets that support unconfined-aquifer water-levels and interpretations for the Cape May 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 is this report which contains unconfined-aquifer water-level data and an interpretation from a comprehensive water-resource study in Cape May County (Spitz, 1998, Lacombe and Carleton, 2002).
Purpose:
The water-levels from streams data for the Cape May 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.
