Featured Product: MODFLOW 6 -- USGS Modular Hydrologic Model

MODFLOW 6, the newest version of the world's most widely used groundwater modeling software, is now available for download from the USGS. Redesigned to improve user experience and accommodate future features, MODFLOW 6 introduces a model coupling framework to the program that, for more than 30 years, has been used by academics, private consultants, and government scientists to accurately, reliably, and efficiently simulate groundwater flow. This updated core version of MODFLOW was redesigned from the ground up to incorporate many of the new advances in groundwater modeling developed over the past decade. The MODFLOW 6 software and user guides are available for download.

Animation of Groundwater Watch Active Water Level Network, 30 days
legend

The USGS Active Groundwater Level Network includes about 20,000 wells that have been measured by the USGS or USGS cooperators at least once within the past 13 months. The animation shows a daily snapshot of water-level statistics in the network for August 2017. Credit: USGS. The image is in the public domain.

Field Photo

USGS collects groundwater data across the Nation. In order to provide consistent, high-quality, reliable data, we use standardized field methods and procedures. In this photo, hydrologists and hydrologic technicians from USGS Water Science Centers participated in an August 2017 class on USGS groundwater field methods. Kim Cesal of the USGS Washington Water Science Center is demonstrating proper site visit and groundwater-level measurement methods. Interested in learning more? USGS groundwater technical procedures and demonstration videos are available online.
