Regular monitoring of groundwater levels can assist in the early detection and understanding of factors affecting groundwater availability, including drought and impacts from land use change.  The GLWQD Monitoring Well Network is designed to provide long-term trend data of groundwater levels over time.  There are 57 active monitoring wells in the network which covers the entire Gallatin Valley. Currently, the wells are checked quarterly.  All data collected from the monitoring well network is entered into the Montana Bureau of Mines and Geology (MBMG) Ground Water Information Center (GWIC) database.  This database is easily accessible and contains a wealth of information on groundwater resources throughout the state of Montana.

For more information on the GLWQD Groundwater Monitoring Program, contact the GLWQD hydrogeologist at (406) 582-3148.
