Our mission is to provide information for the sound use of Montana’s geological and water resources.
Our vision is to be Montana’s lead source of geologic and water information.
As a non-regulatory State agency within the Montana University System, we serve as Montana’s geologic survey, addressing topics ranging from earthquake monitoring and geologic mapping to energy development and groundwater. We are housed on the campus of Montana Technological University and maintain a fully staffed office in Billings.

Managed Aquifer Recharge in Montana: New publication and app
The MBMG recently published a screening study on the potential for managed aquifer recharge (MAR) in Montana. MAR is a method of intentionally recharging groundwater for later use, either through surface infiltration or by injecting water into the subsurface and recovering it during times of need. This study determines locations across the state that appear suitable for MAR surface infiltration methods based on the hydrogeology. Explore this study from the Web Application or the MBMG publication page.

The MBMG GIS Data Hub
The MBMG GIS Data Hub Site is our newly developed interactive web platform for everyone to explore our web maps and analytical web applications. The Hub Site will also provide the download links for GIS data of interest via individual web applications. Geology, geohazards, water resources, environmental studies, energy resources, and mineral resources GIS data is all available via the GIS Hub Site.
