Water well logs are maintained in the MBMG’s Ground-Water Information Center (GWIC). The collection currently includes approximately 250,000 records (both in hard copy and digital formats) describing water-related resources (wells, boreholes, springs, etc.) in Montana. The paper collection is stored in the GWIC offices at the Bureau. The electronic data is stored on an SQL server and is available over the internet at http://mbmggwic.mtech.edu/. In addition to well log data, GWIC is also actively collecting and maintaining: 33,300 water-quality analyses from 14,700 sites, 2.3 million historic water-level records from 12,300 sites, as well as field-inventory and aquifer-test data.
