Groundwater Database Reports

The TWDB's Groundwater Database (GWDB) is available for downloading in the following formats and updated monthly:

  1. Reports have been generated and broken out by county. There are 5 reports per county that combine the most often needed information from all of the database tables. The reports are the Records of Wells, Water Levels, Water Quality, Infrequent Constituent Water Quality and Cooperator Infrequent Constituent Water Quality. The reports are in .pdf format which can be viewed using Adobe Reader.
  2. The entire database in Microsoft Access 2007 format (.mdb) can be downloaded by clicking the file called "Zipped.mdb file of entire Groundwater Database" under the "All Counties Combined" heading.
  3. The entire database in comma delimited .txt files is available (for importing into your own database or spreadsheet) under the "All Counties Combined" heading. There are 8 .txt files for the 8 data tables available. The .txt files under the "Lookup Tables" heading should be downloaded as well.
  4. Comma delimited .txt files for the individual data tables are also split up by county. Download the .txt files under the county headings you need along with the .txt files under the "Lookup Tables" heading.
