The Ground Water Assessment Program was established by the Montana Legislature (85-2-901 et seq.) in 1991 to improve the understanding of Montana's groundwater resources by collecting, interpreting, and disseminating essential groundwater information. This information is vital for making science-based management decisions.
There are three program components:
An interagency Steering Committee selects study areas, coordinates groundwater research among state, federal, and local government units, and oversees Assessment Program progress.
Tracking Montana's Groundwater
The Ground Water Monitoring Program collects quarterly water-level measurements from 900 strategically located wells across the state.
Provides a direct measure of the health of Montana aquifers.
Tracks how aquifers respond to seasonal, climatic, developmental, or land-use factors.
Mapping Montana's Aquifers
The Characterization Program maps and assesses aquifers within specific areas as prioritized by the Ground Water Assessment Steering Committee.
To date, more than 8,000 wells have been visited and about 3,000 groundwater samples have been collected. These data have been used to compile 64 maps and reports that describe aquifer productivity, groundwater flow systems, and groundwater quality.
Storing and delivering Montana's Groundwater Information
The Ground Water Information Center (GWIC) is Montana's groundwater information repository.
The web site (http://mbmggwic.mtech.edu/) provides online access to water-well logs, hydrographs, maps of groundwater flow systems, and water quality reports describing groundwater conditions across the state, as well as a variety of field, chemical, and physical data.
