This Regional Water Table Surface Contours Upper Glacial Drift Lower Peninsula is a generalized water table surface created by using the existing Wellogic water well database as of March 2021 and using just wells screened in the upper portion of the glacial drift. The elevation of the reported static water level (SWL field) reported on the well logs was calculated by subtracting it from the elevation at each well which was based on a 10-meter DEM. The data also incorporated the elevations of the Great Lakes Shorelines and the elevation of hydraulically appropriate surface water bodies (NHD Plus) that appear to be connected to the regional aquifer system and not perched above the regional water table surface. Contours were derived at a 10 feet contour interval. The original data was mapped for the entire lower peninsula. This Kent County data was clipped out of the peninsula data.The fields found in this dataset are:Field NameDescriptionIdUnique integer in long integer formatContourGroundwater elevation value (feet above mean sea level) in double precision formatContour1Groundwater elevation value (feet above mean sea level) in long integer formatINDEXValues in long integer format that allow different index contours to be flagged, labeled, queried, and/or symbolized.INDEX10Values in long integer format that allow different index contours to be flagged, labeled, queried, and/or symbolized.INDEX5Values in long integer format that allow different index contours to be flagged, labeled, queried, and/or symbolized.Shape_LengthLength of line in feet in double precision formatThis data is used in the North Kent Study Area Data Summary Web App (Item Details).
