Layer: Line of equal potentiometric-surface altitude (contour interval 5 feet) (ID: 13)

Parent Layer: Potentiometric surface of the Lloyd & North Shore aquifers

Name: Line of equal potentiometric-surface altitude (contour interval 5 feet)

Display Field: CONTOUR

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: This data set consists of digital contours that represent the potentiometric-surface altitude of water in the Lloyd and contiguous North Shore aquifer beneath Long Island, New York. The U.S. Geological Survey constructed a potentiometric-surface altitude map using ground-water levels measured in the Lloyd and North Shore aquifers during the spring of 2013. Water-level data were collected from 66 wells to construct the contours at a map scale of 1:125,000. The potentiometric-surface altitude contours were digitized and compared to 1997, 2006, and 2010 potentiometric-surface altitude maps . The 5 foot contour interval ranges from -10 to 60 feet above the National Geodetic Vertical Datum of 1929. This geographic information systems (GIS) data set is a digital representation of the potentiometric-surface contours presented in sheet 3 of Scientific Investigations Map 3270.
