    • Geospatial data for groundwater potentiometric-surface maps in northeastern Hamilton, southern Meigs, and northwestern Bradley Counties, Tennessee, fall 1992, spring and fall 1993, summer 2008, and spring 2009

    Metadata Updated: January 21, 2026

    This dataset includes a Microsoft Excel file, and a .csv and a .txt version of the Excel file, that contain location and groundwater-level data for wells open to the Valley and Ridge carbonate aquifer of Cambrian-Ordovician age in the area of Savannah and Gunstocker Creeks in northeastern Hamilton, southern Meigs, and northwestern Bradley Counties, Tennessee, for fall 1992, spring and fall 1993, summer 2008, and spring 2009 conditions. Potentiometric-surface contour data for the five measurement periods also are included as separate Earth Sciences Research Institute (ESRI) ArcGIS shapefiles. The data were collected as parts of studies conducted by the U.S. Geological Survey (USGS) in cooperation with the Chattanooga/Hamilton County Regional Planning Commission, the City of Chattanooga, Hamilton County, the Hamilton County Association of Utility Districts, and the Savannah Valley Utility District (SVUD). The well and water-level data also are available from the USGS National Water Information System (NWIS).
