Recent and Historical Ground Water Level Data

Recent and Historical Ground Water Level Data

Instructions

Data accessible on this page are a subset of DGS holdings and are updated quarterly (March, June, etc.). Click on the data link for the well of interest to download a comma delimited text file of all available water level data for that well. Hydrographs are available for a small subset of wells that have water level recorders. Click on the graph link for the well of interest to download a PDF file containing a hydrograph of daily mean water levels.

For most of the wells water levels were measured in monitoring or observation wells by staff members of the DGS and USGS. For a few wells water levels were measured by employees of consulting firms. Users should be aware that these data records have been checked by DGS staff, however they are subject to revision. If you have questions or require additional information about the wells or measurements, please contact the DGS through the address at the bottom of this page.

This table lists wells having 100 or more water level observations.

Table Heading Descriptions

  • DGSID - DGS well identifier.
  • Easting, Northing - Values are in UTM 1983 coordinates, rounded to the nearest meter.
  • Altitude - Values are in NGVD 1929 elevation of land surface in feet.
  • Screen Top, Screen Bottom - Depth to top and bottom of open or screen interval in ft below land surface.
