Lineage | This polyline file contains the potentiometric contours of two aquifers: the Jordan aquifer, and the combined St. Lawrence, Franconia, and Ironton-Galesville aquifers. Static water elevations from driller's logs in the County Well Index (CWI) and water level measurements by DNR hydrologists during water sampling were combined to create the contour files. The potentiometric contours were initially created using ANUDEM software (Hutchinson, 1996). Hand drawn modifications were done by the DNR Hydrogeologist to incorporate topographic and flowpath information into the contour model. |

Entity and Attribute Overview | |
Entity and Attribute Detailed Citation HTML Table (Not Available) | potsfcln.dbf | | | | CONTOUR | Elevation in feet above mean sea level of the potentiometric surface contour of an aquifer. Contour interval is 25 feet. | | CONFIDENCE | "poor" refers to contour segments where line is uncertain due to inadequate data. "good" refers to a segment that is reliable based on adequate data. | | AQUIFER | Aquifer to which a given potentiometric surface contour belongs. The aquifers are identified as either "Jordan" or "St. Lawrence, Franconia, and Ironton-Galesville". |
