Links to the latest USGS ground-water modeling software, upgrades and bug corrections are posted on this page as soon as new codes become available from the code authors. The links found here will always provide the newest software from various sources.

Previous versions of codes and other USGS software may be found on the USGS Water Resources Applications Software Site maintained by the Hydrologic Analysis Software Support Program (HASS). New codes and revisions appear on the HASS site only after additional quality control. Codes on the current page may be linked to the HASS site when the newest version is available there.
