The new and improved GCD Index is a fully interactive representation of the TAGD GCD database. It includes detailed information about the state’s groundwater conservation districts in an easy map viewer. You may select layers including aquifers and GMA boundaries, click around to identify GCDs in a given area, and even export data from the searchable table below the map. We hope you find this tool easy to use and a valuable addition to our website.
